Examining the validity of pressure ulcer risk assessment scales: developing and using illustrated patient simulations to collect the data

A comparison of two different oral contraceptives in patients with severe primary dysmenorrhoea

Pain relief of two different oral contraceptive pills (OCPs) in severe primary dysmenorrhoea (PD) was compared. Sixty-six nulliparous patients with severe PD requiring contraception were evaluated. Group 1 comprised 33 healthy controls. Patients with severe PD were divided into two groups. Patients in Group 2 were administered oestradiol valerate/dienogest and patients in Group 3 were administered ethinylestradiol/drospirenone. Doppler indices of both uterine arteries (left and right) including systolic/diastolicrates (S/D), pulsatility index (PI) and resistance index (RI) were measured, and a visual analogue scale (VAS) was applied to patients before treatment. VAS scores and Doppler indices were repeated after 3 months of OCP treatment and the changes in values were compared. The demographic and clinical characteristics of the patients were similar. The mean value of RI was significantly lower after therapy in Groups 2 and 3 in the right and left uterine arteries (p = .001 and p = .039, respectively). The clinical trial number was NCT03124524. Impact Statement What is already known on this subject: OCPs are the most appropriate treatment option for PD. There is no clear data about OCP containing dienogest for treatment in PD. Dienogest has been reported to be highly effective in the treatment of endometriosis and is also recommended as first-line therapy for pelvic pain-associated endometriosis. What the results of this study add: In this study, although there was no superiority in pain relief between the treatment groups, lower VAS scores and lower RI values of uterine arteries were seen after treatment. Both OCPs relieve pain in severe PD. There was no serious adverse effect in the patients. What the implications are of these findings for clinical practice and/or further research: Estradiol valerate/dienogest, which is a routinely prescribed drug for heavy menstrual bleeding in women who desire oral contraception, is as effective as ethinylestradiol/drospirenone in pain relief.

Effectiveness of self-management program on arthritis symptoms among older women: A randomized controlled trial study

We aimed to determine the effectiveness of a self-management program amongst older women with rheumatoid arthritis. The intervention group (n = 40) received a six-week arthritis self-management program. Assessments were recorded prior to and after the program using a demographic questionnaire, Visual Analogue Scale, Arthritis Self-Efficacy Scale, and self- reported questions regarding mobility. Significant improvements in self-efficacy for functional ability and pain management were found in the intervention group compared to those before the intervention and the control group. Our trial indicates that the program used in conjunction with exercise interventions for aged patients may lead to benefits perceived self-efficacy.

A Chinese medicine warm compress (Wen Jing Zhi Tong Fang), combined with WHO 3-step analgesic ladder treatment for cancer pain relief: A comparative randomized trial

INTRODUCTION

This study aimed to assess the effectiveness of Chinese medicine warm compress (CMWC) on back meridians in relieving cancer pain, reducing adjuvant analgesic doses and adverse reactions, and improving the quality of life (QOL).

METHODS

A total of 62 patients (age range 39-82 years) diagnosed with a malignant tumor and suffering from cancer-related pain were randomly divided into a treatment group (group A) and a control group (group B) (n = 31 for each). The patients in both groups were administered appropriate drugs for 2 cycles of 7-day treatments according to the World Health Organization (WHO) 3-step ladder for cancer pain relief in adults. In addition, a CMWC was given to patients in group A. Pain relief was assessed using the visual analogue scale (VAS) at various time points before and after interventions in each group. Alteration of analgesic doses, adverse reactions, performance status (PS), and QOL were evaluated and any differences between groups A and B evaluated.

RESULTS

VAS scores at various time points after treatment were significantly decreased compared with the baseline level in group A. Overall response rate was significantly improved in group A compared with group B (70.97% vs 29.03%, P < .001). Significant differences in clinical pain relief efficacy in various locations were found in group A after treatment vs before treatment (P < .05). Adjuvant analgesic doses were significantly changed in the control group compared to the treatment group after 1 cycle of 7-day treatment (22.58% vs 12.90%, P = .023). QOL were improved more in group A than in group B (3.00 ± 4.23 vs -2.06 ± 2.38, P < .001). Significantly reduced adverse reactions were observed after treatment of group A compared with group B in terms of the overall incidence (3.23% vs 80.65%, P < .05) or incidence of constipation (3.23% vs 77.42%, P < .05).

CONCLUSIONS

The application of CMWC on back meridians combined with WHO 3-step analgesic ladder treatment was effective in relieving cancer-related pain with reduced doses, less adverse reactions, and improved QOL.

Preoperative position splint versus skin traction in patients with hip fracture: An experimental study

AIM

The aim of the study was to compare the effects of a preoperative position splint and skin traction on pain, comfort, complications, and satisfaction with the treatment and care for patients with hip fracture.

METHOD

This randomized trial was conducted with a total of 68 patients with hip fracture in a tertiary care hospital in Turkey. Preoperatively, a position splint was applied to the patients in the intervention group (n = 34) and skin traction was applied to patients (n = 34) in the control group. Outcomes studied were pain, comfort, satisfaction and complications.

RESULTS

Mann-Whitney U Test showed a significant difference between the position splint group and skin traction group regarding pain severity after the application (p < .05). A significant difference was demonstrated between the two groups concerning comfort levels after the application (p < .05). The position splint group was significantly more satisfied with the treatment and care than the control group in the later period after the application (p < .05). The number of preoperative complications in the position splint group was significantly fewer than that of the skin traction group in the preoperative period (p < .05).

CONCLUSION

Preoperative position splint application in patients with hip fracture relieved pain and complications and increased comfort and satisfaction with treatment and care.

Extended-Release Injectable Naltrexone (XR-NTX) With Intensive Psychosocial Therapy for Amphetamine-Dependent Persons Seeking Treatment: A Placebo-Controlled Trial

OBJECTIVE

Explore the efficacy of extended-release injectable naltrexone (XR-NTX) for preventing relapse to amphetamine use.

METHOD

Clinical trial of 100 amphetamine-dependent, treatment-seeking patients who were randomized to 6 monthly 380 mg doses of XR-NTX or matching placebo before entering intensive outpatient after varying lengths of inpatient treatment in Reykjavik, Iceland. Weekly urine drug tests, retention, and standardized instruments assessed efficacy.

RESULTS

Of 169 approached, 100 were randomized. Although amphetamine dependence was the main reason for seeking treatment, three-quarters or more of participants had 1 or more other substance dependencies. Of 51 randomized to XR-NTX, 20 received 4 or more injections; of 49 assigned to placebo, 26 received 4 or more injections. Of the planned 2400 weekly urine drug tests, 1247 were collected (52%); 4% of these were positive for amphetamine, 8% for benzodiazepine, 7% for marijuana, 1% for cocaine, and 1% for opioid. XR-NTX had no effect on amphetamine-positive tests, retention, or other outcomes. Those providing half or more of their tests attended more weeks of treatment than those providing less than half of their tests (m = 10.76 vs 3.31; t (92) = 5.91, P < 0.0001), and 92 participants provided at least 1 test.

CONCLUSIONS

Adding XR-NTX to the usual combination of inpatient and intensive outpatient treatment did not reduce amphetamine use. The low prevalence of substance use among collected urine samples, and the association between collected samples and weeks in treatment, was consistent with other studies showing that staying in treatment is associated with better outcomes.

A Clinical Study on Comparative Evaluation of the Effectiveness of Carbamazepine and Combination of Carbamazepine with Baclofen or Capsaicin in the Management of Trigeminal Neuralgia

Background:

Trigeminal neuralgia (TN) is characterized by recurrent attacks of lancinating pain in the trigeminal nerve distribution. Various medicinal and surgical procedures have been utilized for the treatment of TN. Over the time, several drugs other than carbamazepine have been used but none of them have shown satisfying results.

Objective:

The objective of the study is to evaluate the effectiveness of carbamazepine and combination of carbamazepine with baclofen or capsaicin in the management of TN.

Materials and Methods:

A total of 45 patients diagnosed with TN were randomly divided into three groups. The patients were prescribed carbamazepine in Group 1, carbamazepine and baclofen in Group 2, and carbamazepine and capsaicin in Group 3. All the patients were followed on the 7^th day, 15^th day, and 1-month period to evaluate the response to the drugs. Data were subjected to statistics.

Results:

The results are composed of a total of 45 patients (15 in each group). The mean visual analogue scale scores were calculated for each group at day 0, 7^th day, 15^th day, and 30 days, and it was found that there was statistically significant reduction of pain (P < 0.001) in all the three groups at different intervals. At day 7, comparative percentage reduction of pain in both groups was not statistically significant. At 15-days and 30 days, percentage change in pain reduction in Group 1 was 42.3% and 48.0% respectively and in Group 2 it was found to be 60.3% and 83.4%, respectively. The reduction in pain percentage was found to be statistically significant. Similarly, Group 1 was compared to Group 3, significant reduction of pain was found for carbamazepine-capsaicin combination at 30-day interval but the comparative reduction of pain at 7^th day and 15^th day was not statistically significant.

Conclusion:

Carbamazepine in combination with baclofen is more efficient and effective in reducing pain in TN patients, followed by carbamazepine-capsaicin combination compared to carbamazepine alone.

Outcomes of operative and nonoperative treatment of 3- and 4-part proximal humeral fractures in elderly: a 10-year retrospective cohort study

Purpose

Despite a rising incidence in proximal humeral fractures, there is still no evidence for the best treatment option, especially for elderly patients. The aim of this retrospective cohort study was to evaluate health-related quality of life (HRQoL), functional outcome, pain and social participation in elderly patients, after operative and nonoperative treatment of displaced 3- and 4-part proximal humeral fractures.

Methods

150 patients aged ≥ 65, treated for a displaced 3- or 4-part proximal humeral fracture between 2004 and 2014, were invited to participate. Eventually 91 patients (61%) participated, of which 32 non-operatively treated patients were matched to 32 of the 59 operatively treated patients by propensity score matching. The EQ-5D, DASH, VAS for pain and WHODAS 2.0 Participation in Society domain were administered. Complications and reinterventions were registered.

Results

No significant difference was found between the two treatment groups in HRQoL (p = 0.43), function (p = 0.78) and pain (p = 0.19). A trend toward better social participation in the operative group (p = 0.09) was found. More complications and reinterventions occurred in the operative group than the nonoperative group, with 9 versus 5 complications (p = 0.37) and 8 versus 2 reinterventions (p = 0.08).

Conclusions

In this study, we found no evidence of a difference in HRQoL, functional outcome or pain 1–10 years after operative or nonoperative treatment in patients of 65 and older with a displaced 3- or 4-part humeral fracture. Operatively treated patients showed a trend toward better social participation but also higher reintervention rates.

No significant correlation between the intensity of static stretching and subject's perception of pain

[Purpose] The purpose of this study was to determine whether the intensity of static stretching measured quantitatively is related to subjects’ perception of pain. [Subjects and Methods] Sixty-eight participants were recruited. Static stretching was performed once for 30 seconds while maintaining the knee at 0° flexion and was continued to the point where pain was recognized. The intensity of stretching exerted by the practitioner was quantitatively measured by using a handheld dynamometer (HHD). A subject’s pain scaled on one’s perception was measured by using the visual analog scale (VAS). [Results] No significant correlation was found between the intensity of stretching and the VAS score representing the subject’s pain scaled on one’s perception. In this study, the most frequent VAS score was 7, and the mean VAS score was 5.57 ± 1.77. The stretching intensity measured by using a HHD ranged from 28.4 to 133.0 N (mean, 72.04 ± 22.37 N). [Conclusion] This study showed that the intensity of stretching quantitatively measured by using HHD did not correlate with the degree of pain reported by the subjects. Therefore, subjective responses cannot guarantee a consistent application of intensity.

Theoretical Perspectives of Hospitalized Older Patients and Their Health-Related Problems and Quality of Care: Systematic Literature Review

Introduction:

The proportion of aged people is growing worldwide. Older persons are affected by a number of physical, psychological and social factors that influence their health and quality of life. These factors are usually multiple and are often masked by sensory and cognitive impairments.

Purpose:

The purpose of this study was to examine the available literature emphasizing older persons’ care, care-related problems, and older persons’ quality of healthcare. Also, the paper aimed at exploring the future direction of research needs.

Results:

Good quality older patients’ care involves safety, professional interventions, recognition and management of physical and emotional wellbeing. Care of older patients requires addressing the aging process itself, the expected decrease in functionality, and diminished cognitive ability. Little statistical data were found to address the quality of hospitalized elderly patients in particular as well as study on healthcare facilities and nursing homes. Literature does not provide much guidance to the effectiveness of care strategies.

Conclusion:

The results assert that elderly health care is a priority. However, health care systems are not specific about elderly patients’ needs, leading to low quality of elderly care. There is a need to use an integrated model of care to improve the quality of life and quality of care provided to hospitalized older patients.

Usability Test of Exercise Games Designed for Rehabilitation of Elderly Patients After Hip Replacement Surgery: Pilot Study

BACKGROUND

Patients who receive rehabilitation after hip replacement surgery are shown to have increased muscle strength and better functional performance. However, traditional physiotherapy is often tedious and leads to poor adherence. Exercise games, provide ways for increasing the engagement of elderly patients and increase the uptake of rehabilitation exercises.

OBJECTIVE

The objective of this study was to evaluate Fietsgame (Dutch for cycling game), which translates existing rehabilitation exercises into fun exercise games. The system connects exercise games with a patient's personal record and a therapist interface by an Internet of Things server. Thus, both the patient and physiotherapist can monitor the patient's medical status.

METHODS

This paper describes a pilot study that evaluates the usability of the Fietsgame. The study was conducted in a rehabilitation center with 9 participants, including 2 physiotherapists and 7 patients. The patients were asked to play 6 exercise games, each lasting about 5 min, under the guidance of a physiotherapist. The mean age of the patients was 74.57 years (standard deviation [SD] 8.28); all the patients were in the recovery process after hip surgery. Surveys were developed to quantitatively measure the usability factors, including presence, enjoyment, pain, exertion, and technology acceptance. Comments on advantages and suggested improvements of our game system provided by the physiotherapists and patients were summarized and their implications were discussed.

RESULTS

The results showed that after successfully playing the games, 75% to 100% of the patients experienced high levels of enjoyment in all the games except the squats game. Patients reported the highest level of exertion in squats when compared with other exercise games. Lunges resulted in the highest dropout rate (43%) due to interference with the Kinect v2 from support chairs. All the patients (100%) found the game system useful and easy to use, felt that it would be a useful tool in their further rehabilitation, and expressed that they would like to use the game in the future. The therapists indicated that the exercise games highly meet the criteria of motor rehabilitation, and they intend to continue using the game as part of their rehabilitation treatment of patients. Comments from the patients and physiotherapists suggest that real-time corrective feedback when patients perform the exercises wrongly and a more personalized user interface with options for increasing or decreasing cognitive load are needed.

CONCLUSIONS

The results suggest that Fietsgame can be used as an alternative tool to traditional motor rehabilitation for patients with hip surgery. Lunges and squats are found to be more beneficial for patients who have relatively better balance skills. A follow-up randomized controlled study will be conducted to test the effectiveness of the Fietsgame to investigate how motivating it is over a longer period of time.

A matched-pair comparison of inlay and onlay trochlear designs for patellofemoral arthroplasty: no differences in clinical outcome but less progression of osteoarthritis with inlay designs

PURPOSE

To compare clinical and radiographic results after isolated patellofemoral arthroplasty (PFA) using either a second-generation inlay or onlay trochlear design. The hypothesis was that an inlay design will produce better clinical results and less progression of tibiofemoral osteoarthritis (OA) compared to an onlay design.

METHODS

Fifteen consecutive patients undergoing isolated PFA with an onlay design trochlear component (Journey™ PFJ, Smith & Nephew) were matched with 15 patients after isolated PFA with an inlay design trochlear component (HemiCAP^® Wave, Arthrosurface). Matching criteria were age, gender, body mass index, and follow-up period. An independent observer evaluated patients prospectively, whereas data were compared retrospectively. Clinical outcome was assessed using WOMAC, Lysholm score, and pain VAS. Kellgren-Lawrence grading was used to assess progression of tibiofemoral OA.

RESULTS

Conversion to total knee arthroplasty was necessary in one patient within each group, leaving 14 patients per group for final evaluation. The mean follow-up was 26 months in the inlay group and 25 months in the onlay group (n.s.). Both groups displayed significant improvements of all clinical scores (p < 0.05). No significant differences were found between the two groups with regard to the clinical outcome and reoperation rate. No significant progression of tibiofemoral OA was observed in the inlay group, whereas 53 % of the onlay group showed progression of medial and/or lateral tibiofemoral OA (p = 0.009).

CONCLUSION

Isolated PFA using either a second-generation inlay or onlay trochlear component significantly improves functional outcome scores and pain. The theoretical advantages of an inlay design did not result in better clinical outcome scores; however, progression of tibiofemoral OA was significantly less common in patients with an inlay trochlear component. This implant design may therefore improve long-term results and survival rates after isolated PFA.

Fatigue in Younger and Older Drivers: Effectiveness of an Alertness-Maintaining Task

OBJECTIVE

The aim of this study was to examine the effects of an alertness-maintaining task (AMT) in older, fatigued drivers.

BACKGROUND

Fatigue during driving increases crash risk, and previous research suggests that alertness and driving in younger adults may be improved using a secondary AMT during boring, fatigue-eliciting drives. However, the potential impact of an AMT on driving has not been investigated in older drivers whose ability to complete dual tasks has been shown to decline and therefore may be negatively affected with an AMT in driving.

METHOD

Younger ( n = 29) and older drivers ( n = 39) participated in a 50-minute simulated drive designed to induce fatigue, followed by four 10-minute sessions alternating between driving with and without an AMT.

RESULTS

Younger drivers were significantly more affected by fatigue on driving performance than were older drivers but benefitted significantly from the AMT. Older drivers did not demonstrate increased driver errors with fatigue, and driving did not deteriorate significantly during participation in the AMT condition, although their speed was significantly more variable with the AMT.

CONCLUSION

Consistent with earlier research, an AMT applied during fatiguing driving is effective in improving alertness and reducing driving errors in younger drivers. Importantly, older drivers were relatively unaffected by fatigue, and use of an AMT did not detrimentally affect their driving performance.

APPLICATION

These results support the potential use of an AMT as a new automotive technology to improve fatigue and promote driver safety, though the benefits of such technology may differ between different age groups.

The Gaps between Knowing and Doing in Hearing Aid Fitting Management

Evidence based practice has become an important aspect in many healthcare provisions to improve patient outcomes. Investigating the gaps between knowing and doing in audiology practice will provide future directions for successful service delivery. The purpose of this study was to explore "know-do" gaps related to professional awareness and attitude in hearing aid fitting management (HAFM) by analyzing data of a questionnaire. It consisted of 22 questions focusing on 11 HAFM components. Each component had two sub-questions involving levels of the importance and practice for HAFM. Respondents answered each question based on subjective judgments for their own hearing aid fitting services with a Visual Analogue Scale. A total of 51 responses from hearing care professionals were collected and the scores for knowing and doing were compared. The results showed overall high scores in doing and knowing responses; however, there were significant "know-do" gaps demonstrating higher knowing scores than doing scores across all HAFM components. The largest "know-do" gaps were observed in three components mostly implemented during follow-up sessions which indicate the need to improve their corresponding services and practical guidelines emphasizing the follow-up services.

Effectiveness and safety of moxibustion treatment for non-specific lower back pain: protocol for a systematic review

INTRODUCTION

Many patients experience acute lower back pain that becomes chronic pain. The proportion of patients using complementary and alternative medicine to treat lower back is increasing. Even though several moxibustion clinical trials for lower back pain have been conducted, the effectiveness and safety of moxibustion intervention is controversial. The purpose of this study protocol for a systematic review is to evaluate the effectiveness and safety of moxibustion treatment for non-specific lower back pain patients.

METHODS AND ANALYSIS

We will conduct an electronic search of several databases from their inception to May 2017, including Embase, PubMed, Cochrane Central Register of Controlled Trial, Allied and Complementary Medicine Database, Wanfang Database, Chongqing VIP Chinese Science and Technology Periodical Database, China National Knowledge Infrastructure Database, Korean Medical Database, Korean Studies Information Service System, National Discovery for Science Leaders, Oriental Medicine Advanced Searching Integrated System, the Korea Institute of Science and Technology, and KoreaMed. Randomised controlled trials investigating any type of moxibustion treatment will be included. The primary outcome will be pain intensity and functional status/disability due to lower back pain. The secondary outcome will be a global measurement of recovery or improvement, work-related outcomes, radiographic improvement of structure, quality of life, and adverse events (presence or absence). Risk ratio or mean differences with a 95% confidence interval will be used to show the effect of moxibustion therapy when it is possible to conduct a meta-analysis.

ETHICS AND DISSEMINATION

This review will be published in a peer-reviewed journal and will be presented at an international academic conference for dissemination. Our results will provide current evidence of the effectiveness and safety of moxibustion treatment in non-specific lower back pain patients, and thus will be beneficial to patients, practitioners, and policymakers.

Health-related quality of life after open-wedge high tibial osteotomy

PURPOSE

(1) To monitor longitudinal changes in health-related quality of life (HRQOL), pain, knee function, and return to work (RtW) following high tibial osteotomy (HTO) for medial compartment osteoarthritis (OA), and (2) to investigate the influences of psychopathological comorbidities on preoperative impairment and post-operative course.

METHODS

Sixty-four patients were prospectively followed for 24 months after HTO to determine HRQOL, pain, functional outcome, and RtW. Psychopathological comorbidities (e.g. depression) were determined preoperatively. Patients with no psychological distress (ND) were compared to patients with psychological distress (PD) in order to investigate the influence of psychopathological comorbidities on outcome.

RESULTS

There was a significant increase in HRQOL and decrease in pain from 6 month follow-up on. Functional outcomes increased significantly from 12 month follow-up on. In general, there was a steady state of outcomes from 6- to 12-month follow-up on. At final follow-up, 90 % returned to their previous occupation without limitations. Mental component summary (MCS) and functional outcome showed a positive correlation with RtW, while depression had a negative one. A significantly inferior outcome of group PD versus ND was observed at baseline and early follow-up. RtW was significantly prolonged in group PD (8.9 ± 7.6 vs. 3.9 ± 3 months; p < 0.001). At final follow-up, both groups presented with comparable outcomes.

CONCLUSION

HTO for medial compartment OA significantly improves HRQOL, pain, and knee function. Time to RtW is high and critically depends on PD. Further, extend of preoperative impairments, an initially inferior course, and inferior MCS outcome was influenced by PD. However, otherwise no significant differences were observed between groups PD and ND at final follow-up.

[Patellofemoral arthroplasty]

OBJECTIVE

Isolated resurfacing of the trochlea using an inlay prosthesis without changing the complex kinematics of the patellofemoral joint.

INDICATIONS

Symptomatic, isolated patellofemoral osteoarthritis or isolated osteochondral lesions, failed conservative and cartilage regeneration procedures. No or concurrently corrected ligament instability, tibiofemoral and patellofemoral malalignment.

CONTRAINDICATIONS

Symptomatic patellofemoral osteoarthritis, inflammatory joint disease, chondrocalcinosis, chronic pain syndromes, active infections or knee ankylosis.

SURGICAL TECHNIQUE

Following a medial arthrotomy, coronal and sagittal curvatures of the trochlea are measured. Based on these measurements, corresponding surface reamers create an implant bed by removing damaged cartilage of the trochlea. A central fixation screw is placed to the desired depth and the inlay prosthesis is tapped carefully onto it. Final placement of the prosthesis is targeted slightly recessed to the surrounding joint surface.

POSTOPERATIVE MANAGEMENT

Free passive range of motion exercises of the knee joint are recommended starting on postoperative day 1. Depending on symptoms (e.g., pain and joint effusion), partial weight-bearing of 20 kg is allowed during postoperative weeks 1 and 2, which is increased by 20 kg/week thereafter.

RESULTS

In a prospective study of 29 patients (mean age: 42 years) treated with inlay arthroplasty, 2‑year follow-up results showed significant improvements (p < 0.05) in WOMAC, IKDC and VAS (pain) scores when compared to baseline. Compared to onlay PF arthroplasty modern inlay prosthetic placement showed a better preservation of the tibiofemoral joint without progression of tibiofemoral degeneration. This may be due to possible avoidance of patellofemoral overstuffing using a more physiological placement of the inlay prosthesis.

Patient-centered Microsurgical Management of Gingival Recession using Coronally Advanced Flap with Either Platelet-rich Fibrin or Connective Tissue Graft: A Comparative Analysis

Purpose:

To evaluate autologous platelet-rich fibrin (PRF) and autogenous connective tissue graft (CTG) in gingival recession defects in conjunction with coronally advanced flap (CAF) using a microsurgical technique.

Materials and Methods:

Forty-five Class I and II recession defects were randomly equally (n = 15) divided into three groups: Group I sites treated with CAF with PRF, Group II sites treated with CAF with CTG, and Group III sites treated with CAF alone using microsurgical approach. Parameters recorded were vertical gingival recession (VGR) and horizontal gingival recession (HGR), % complete root coverage (CRC), patient comfort score (PCS), patient esthetic score (PES), and hypersensitivity score (HS) at 10 days, 3 months, and 6 months.

Results:

CAF surgery alone and in combination with PRF or CTG are effective procedures to cover denuded roots with mean VGR values of 1.26 ± 0.70 mm (74.4%), 1.26 ± 0.59 mm (58%), and 1.06 ± 0.79 mm (53.3%) for Groups I, II, and III, respectively. In terms of CRC achieved at 6 months, results showed that 100% CRC was obtained in 60% sites of Group I, 20% sites of Group II, and 27% sites of Group III. Patient response and acceptance for surgical treatment modality in terms of PCS and PES were highest for Group I (PRF and CAF) followed by Group III and Group II, and there was decrease in HS for Group I (PRF and CAF) while no significant changes in HS were observed for Group II and Group III. At the end of 6 months follow-up, there was a significant increase in gingival thickness measurements using transgingival probing in Group II, whereas nonsignificant changes were observed in Group I and Group III.

Conclusions:

A long-term multicenter randomized controlled clinical study may be necessary to evaluate the clinical outcome for autologous PRF in comparison to CTG and CAF alone.

Morphine versus methylprednisolone or aminophylline for relieving dyspnea in patients with advanced cancer in China: a retrospective study

Context

Dyspnea is one of the most common and distressing symptoms that occurs in terminal cancer patients. However, there are no existing treatment guidelines for this condition in China.

Objective

This single-center, retrospective, observational study aimed to compare the efficacy of using morphine, methylprednisolone, or aminophylline to relieve the symptom of breathlessness in patients with advanced malignant tumors and to investigate the safety of these regimens during the treatment of dyspnea.

Methods

Between August 2011 and January 2015 we retrospectively reviewed the medical records of 343 terminally ill cancer patients with dyspnea who received morphine, methylprednisolone, or aminophylline. The therapeutic effect of each treatment by means of visual analogue scale (VAS) scores was assessed and compared. Statistical methods included Chi square and analysis of variance tests. Differences were considered significant when P < 0.05.

Results

VAS scores after treatment were (16.82 ± 10.89), (25.72 ± 15.03), and (31.95 ± 16.00) points in the morphine, methylprednisolone, and aminophylline group, respectively. These differences were found to be significantly different (P < 0.05). The effectiveness ratings were 86.44, 62.16, and 49.12%, respectively (P < 0.05).

Conclusions

We found that morphine subcutaneous injection for advanced cancer patients with dyspnea was safe and typically more effective than methylprednisolone or aminophylline. Therefore, morphine treatment could significantly improve the quality of life in terminal cancer patients with short life expectancies who are experiencing shortness of breath.

Ranges of motion after reverse shoulder arthroplasty improve significantly the first year after surgery in patients with rheumatoid arthritis

OBJECTIVES

To evaluate the trajectory of the change in range of motion after reverse shoulder joint replacement during 3-year follow-up among patients with rheumatoid arthritis.

METHODS

Retrospective cohort longitudinal study of 76 shoulder replacements performed in a university clinic. The range of shoulder motion was assessed by a physiotherapist using a manual goniometer with 5-degree precision before the surgery and 1, 3, 6, 12, and 36 months postoperatively.

RESULTS

The shapes of the regression curves suggest that the improvement or decline observed in joint motion was happening mostly during the first year after surgery. After 1 year, the trajectories become flat and they remained unchanged until the end of follow-up.

CONCLUSIONS

After shoulder joint replacement, the range of shoulder motion showed substantial changes during the first year only. This should be taken into account when scheduling control visits, planning rehabilitation, and predicting the use of community services after the surgery.

Five-year experience with the adjustable transobturator male system for the treatment of male stress urinary incontinence: a single-center evaluation

BACKGROUND

We report on our 5-year experience with the adjustable transobturator male system (ATOMS^®, A.M.I., Feldkirch, Austria).

METHODS

Between 10-2009 and 10-2014, 54 patients received an ATOMS. The mean follow-up of this retrospective observational trial was 27.5 ± 18.4 (2.3-59) months. Within each follow-up, the following were evaluated: micturition protocol, 24-h pad count, uroflowmetry and residual volume. Statistical analysis was performed with SigmaPlot^® 11.0, p < 0.05 considered as significant.

RESULTS

Stress urinary incontinence (SUI) I°, II° and III° was seen in 1 (1.9 %), 16 (29.6 %) and 37 patients (68.5 %), respectively. In summary, 48.1 % of the patients became "dry" (0-"safty pad"/day), while 29.6 % achieved at least an "improvement" of about more than 50 % (1-2 pads/day), which corresponds to an overall success rate of 77.7 %. The mean number of pads/day decreased from 7.7 to 1.6. Regarding the initial degree of SUI, patients with mild or moderate incontinence had a significantly better outcome (p = 0.002, 95 % CI 0.9066 to 2.760). Postoperative complications were scaled according to the Clavien classification, in which we have seen 4 grade I-, 1 grade IIIa- and 9 grade IIIb-complications (overall 25.9 %). The evaluation of quality of life by ICIQ-SF showed a significant improvement (p = 0.0001, 95 % CI -14.56 to -11.75).

CONCLUSION

The treatment of male SUI using the ATOMS incontinence system achieved the best results in patients with mild and moderate incontinence. For severe incontinent patients, the system represents an efficient alternative.

A clinical trial comparing Lanconone® with ibuprofen for rapid relief in acute joint pain

BACKGROUND

To study the effect of Lanconone® (1000 mg) on acute pain on exertion as compared to the standard of care, Ibuprofen (400 mg).

METHOD

The study recruited 72 subjects diagnosed with mild to moderate knee joint pain on exertion. Subjects with Pain Visual Analogue Scale of more than 40 mm were included. Uphill walking was provided as the stressor using Naughton's protocol on a treadmill. The subjects walked for 10 minutes continuously followed by a rest period and baseline pain score for index knee joint was recorded. Subjects were administered a single dose of Lanconone® (1000 mg)/Ibuprofen (400 mg). Thereafter the same stressor was provided at 0.5, 1, 2, 3, 4, and 6 hours, subsequently, pain scores were recorded on a visual analogue scale. Double stopwatch method was used to evaluate the onset of pain relief and time taken to meaningful pain relief.

RESULT

Both Lanconone® and Ibuprofen showed the first perceived pain relief at 65.31 ± 35.57 mins as compared to 60.82 ± 32.56 mins respectively. The mean time taken to experience meaningful pain relief in Lanconone® group was 196.59 ± 70.85 mins compared to 167.13 ± 71.41 mins amongst Ibuprofen group. The meaningful pain relief continued for 6 hours.

CONCLUSION

The current study successfully demonstrated rapid pain-relieving potential of Lanconone® which was comparable to Ibuprofen. No adverse event related to the interventions was reported in the study.

Effect of dexamethasone in low volume supraclavicular brachial plexus block: A double-blinded randomized clinical study

BACKGROUND AND AIMS

With the use of ultrasound, a minimal effective volume of 20 ml has been described for supraclavicular brachial plexus block. However achieving a long duration of analgesia with this minimal volume remains a challenge. We aimed to determine the effect of dexamethasone on onset and duration of analgesia in low volume supraclavicular brachial plexus block.

MATERIAL AND METHODS

Sixty patients were randomly divided into two groups of 30 each. Group C received saline (2 ml) + 20 ml of 0.5% bupivacaine and Group D received dexamethasone (8 mg) + 20 ml of 0.5% bupivacaine in supraclavicular brachial plexus block. Hemodynamic variables and visual analog scale (VAS) score were noted at regular intervals until 450 min. The onset and duration of sensory and motor block were measured. The incidence of "Halo" around brachial plexus was observed. Student's t-test and Chi-square test were used for statistical analysis.

RESULTS

The onset of sensory and motor block was significantly earlier in dexamethasone group (10.36 ± 1.99 and 12 ± 1.64) minutes compared to control group (12.9 ± 2.23 and 18.03 ± 2.41) minutes. The duration of sensory and motor block was significantly prolonged in dexamethasone group (366 ± 28.11 and 337.33 ± 28.75) minutes compared to control group (242.66 ± 26.38 and 213 ± 26.80) minutes. The VAS score was significantly lower in dexamethasone group after 210 min. "Halo" was present around the brachial plexus in all patients in both the groups.

CONCLUSION

Dexamethasone addition significantly increases the duration of analgesia in patients receiving low volume supraclavicular brachial plexus block. No significant side-effects were seen in patients receiving dexamethasone as an adjunct.

Promising Option for Treatment of Striae Alba: Fractionated Microneedle Radiofrequency in Combination with Fractional Carbon Dioxide Laser

Background. A consistent treatment has not been proposed for treatment of Striae Alba (SA). The present study was designed to compare the fractionated microneedle radiofrequency (FMR) alone and in combination with fractional carbon dioxide laser (FMR + CO₂) in the treatment of SA. Methods. Forty-eight pairs of SA from six patients were selected. Right or left SAs were randomly assigned to one of the treatment groups. The surface area of the SA before and after treatment and clinical improvement using a four-point scale were measured at the baseline, after one and three months. Results. The mean age of the patients was 30.17 ± 5.19 years. The mean difference of the surface area between pre- and posttreatment in the FMR + CO₂ group was significantly higher than that in the FMR group (p = 0.003). Clinical improvement scales showed significantly higher improvement in the FMR + CO₂ group than in the FMR group in the first and second follow-up (p = 0.002 and 0.004, resp.). There were no major persistence side-effects in both groups. Conclusions. The results showed that FMR + CO₂ laser was more effective than FMR alone in the treatment of SA.

The Role of Ideal Angles, Ratios, and Divine Proportions in Aesthetic Evaluation of Adolescents

OBJECTIVES

The aim of our study was to investigate whether the parameters of ideal angles, ratios, and divine proportions that have been previously mentioned in the literature influence the aesthetic evaluation of Turkish adolescents.

MATERIALS AND METHODS

A total of sixty patients (30 males and 30 females) were enrolled in this study. Ages of the subjects ranged from 9 to 17. Pre-treatment extra-oral photographs were taken to evaluate facial aesthetics. Two distinct panels consisting of 50 orthodontists and 50 laypersons were created for scoring the photographs of the patients. Scoring was performed using the VAS scale. Twenty-seven ratios and 19 divine proportions were measured in frontal photographs, and 26 angles were measured in profile photographs.

RESULTS

Pearson correlation was used to determine the relationship between the photograph analysis measurements and VAS scores, and then regression analyses were performed to disclose to what extent significant values may warrant the term beauty.

CONCLUSION

As a result of our investigations, none of the golden proportions was associated with facial aesthetics according to both orthodontists and laypersons. According to other angles and ratios that were measured, it was determined that orthodontists noticed the sagittal position of the lower jaw, the distance between the eyes and length of the face, whereas laypersons noticed only the distance between the eyes and length of the face.

Nurse teacher candidates learned to use social media during the international teacher training course

The purpose of this study was to describe the nurse teacher candidates' learning outcomes and experiences in social media during the international nurse teacher training course, Empowering learning environments in nursing education, Intensive Program (EleneIP). The pre-post research design was used. The data was collected before and after the course, with the questionnaire consisting of structured and open questions. Altogether, 24 nurse teacher candidates from four different European countries participated in the course and this study. The results showed that the knowledge of using social media applications increased during the course from 5.2 (range 1-9) to 8.1 (range 4-10), and their skills increased from 4.5 (range 1-8) to 7.6 (range 4-10).The main topics learnt during the course were divided in two categories: subjects of the course and teaching and learning methods. The students' experiences concerning the EleneIP course were positive in both categories. The international group created during EleneIP course also allowed the students to achieve another important aim, learning from a collaborative group the importance and possibilities of different learning environments, considering the cultural and social characteristics of each country participating in it.

Patient-centered evaluation of microsurgical management of gingival recession using coronally advanced flap with platelet-rich fibrin or amnion membrane: A comparative analysis

OBJECTIVE

To evaluate the efficacy of coronally advanced flap (CAF) procedure under microsurgical approach for the management of Miller's Class I and II gingival recession defects with the use of either platelet-rich fibrin (PRF) or amnion membrane (AM) in comparison to CAF alone.

MATERIALS AND METHODS

A total of 45 sites with Miller's Class I or II gingival recession defect were randomly distributed for: Experimental Group I (CAF with PRF) sites (n = 15) which were treated with the microsurgical approach using CAF along with PRF; experimental Group II (CAF with AM) sites (n = 15) were treated with the microsurgical approach using CAF along with AM; control Group III (CAF alone) sites (n = 15) were treated with the microsurgical approach using CAF alone. Vertical gingival recession (VGR), horizontal gingival recession (HGR), gingival thickness (GT) (using transgingival probing [TGP] and ultrasonography [USG]) and patients' response and acceptance were documented at baseline, 3 months and 6 months after surgical interventions.

RESULTS

CAF alone and in combination with PRF or AM, were effective techniques for root coverage with average VGR values of 1.47 ± 0.92 mm (56%), 0.67 ± 1.23 mm (36%) and 0.60 ± 1.06 mm (33%) in Group I (CAF with PRF), Group II (CAF with AM), and Group III (CAF alone), respectively. Complete coverage (100%) was obtained in 33.3% sites of Group I (CAF with PRF), 26.6% sites of Group II (CAF with AM) and 13.3% in Group III (CAF alone). Patients' response and acceptance for surgical treatment modality in terms of patient esthetic score and decrease in hypersensitivity score was highest for Group I (CAF with PRF), whereas patient comfort score was highest for Group II (CAF with AM). At 6 months follow-up, significant increase in GT measurements (using TGP and USG) in Group I (CAF with PRF), whereas, nonsignificant increase for Group II (CAF with AM) and no change or decrease for Group III (CAF alone) as compared to baseline was observed.

CONCLUSION

The present study observed enhancement in root coverage when PRF or AM are used in conjunction with CAF as compared to CAF alone. These results are based on 6-month follow-up. Therefore, the long-term evaluation may be necessary to appreciate the clinical effect of autologous PRF and AM.

Comparative Efficacy of Amoxicillin/Clavulanic Acid and Levofloxacin in the Reduction of Postsurgical Sequelae After Third Molar Surgery: A Randomized, Double-Blind, Clinical Trial in a Nigerian University Teaching Hospital

Background:

The most common sequelae after surgical removal of mandibular third molar are pain, trismus, swelling, and dysphagia. However, these symptoms can also signal the onset of surgical site infection and alveoli osteitis. The aim of this study was to evaluate the efficacy of prophylactic amoxicillin/clavulanic acid and levofloxacin and preemptive therapy of amoxicillin/clavulanic acid in the reduction of postinflammatory complications, surgical site infection, and alveolar osteitis following the third molar surgery.

Patients and Methods:

A total of 135 patients were randomized into three equal groups: Group A (preemptive therapy of amoxicillin/clavulanic acid) with preoperative dose of 875/125 mg amoxicillin/clavulanic acid followed by 500/125 mg amoxicillin/clavulanic acid 12 hourly for 5 days, Group B (amoxicillin/clavulanic acid prophylaxis) with a single preoperative dose of amoxicillin/clavulanic acid 875/125 mg tablets, and Group C (levofloxacin prophylaxis) with a single preoperative dose of levofloxacin 1000 mg tablets. All patients had ostectomy using surgical handpiece and burs and received same analgesics (tabs ibuprofen 400 mg 8 hourly for 3 days).

Results:

No case of surgical site infection or alveoli osteitis was recorded in the study groups. There were no statistically significant differences between the treatment groups with regard to pain, mouth opening, postoperative facial dimension, and body temperature.

Conclusion:

Amoxicillin/clavulanic acid as a single preoperative bolus should be adequate for the prevention of postoperative wound infection and alveoli osteitis following the third molar extraction as there is no need for an extension of the antibiotic. Moreover, levofloxacin can be utilized as prophylaxis in patients undergoing mandibular third molar extraction if such patients are allergic to penicillins.

Placebo by Proxy--the Influence of Parental Anxiety and Expectancy on Postoperative Morbidities in Children

BACKGROUND

Placebo effects emerging from expectancies of relatives, also known as placebo by proxy, is a rather unexplored field. In this study, we assume a correlation between parental anxiety/expectancy and postoperative morbidities in children. Accordingly, a reduction of parental anxiety is expected to enhance the effect of treatment.

METHODS

From October 2012 to June 2013, parents of 282 children completed a self-report closed-ended questionnaire embedded in a main RCT at three ambulatory care centers.

RESULTS

There were no significant associations between parental expectancy or anxiety and children experiencing vomiting and pain.

CONCLUSION

The present study is the first to investigate placebo by proxy in acupuncture treatment for children. The findings were not able to demonstrate any placebo effect by proxy. Unknown confounders and limitations of methods may have contributed to the negative findings. Thus, the findings must be read with precaution, as the possibility of a type II error cannot be excluded.

Prospective evaluation of a new plate fixator for valgus-producing medial open-wedge high tibial osteotomy

PURPOSE

The purpose of this study was to prospectively evaluate the clinical, radiographic, and sports-related outcome at 24 months after valgus-producing medial open-wedge high tibial osteotomy (owHTO) using a 2nd generation peek-carbon composite plate.

METHODS

Between 2010 and 2011, the 2nd generation PEEKPower HTO-Plate(®) was used for medial owHTO in 28 consecutive patients (19 men, 9 women; mean age ± SD: 45 ± 11 years; mean varus deviation ± SD: 4° ± 2°). All of the patients had an osteotomy gap height of ≤12 mm without bone grafting. Visual analog scale (VAS) for pain, WOMAC score, and Lysholm score were evaluated preoperatively and at 12 and 24 months postoperatively. Sports-related outcomes included the Tegner scale, and a self-designed questionnaire preoperatively and 24 months postoperatively. Fixation stability of the implant was evaluated radiographically in two planes by comparing the medial proximal tibial angle (MPTA) and tibial slope 2 days after medial owHTO (baseline measurements) and after implant removal (follow-up measurements). Complications were recorded during the whole study period.

RESULTS

Compared to preoperative conditions, VAS, WOMAC, and Lysholm scores improved significantly (p < 0.05) at the 12- and 24-month follow-up. No significant differences were found between the 12- and 24-month follow-up. After 24 months, the sports frequency increased significantly (p < 0.05). No significant differences between baseline and follow-up measurements for the MPTA and tibial slope were observed. Total complication rate was 4 %, with one patient developing non-union.

CONCLUSION

In the clinical practice, the 2nd generation PEEKPower HTO-Plate(®) is a safe and efficient implant for medial owHTO without bone grafting in patients with an osteotomy gap of ≤12 mm.

Evaluation of Patients' Satisfaction after Class III Orthognathic Surgery

BACKGROUND

Well-planned orthognathic surgery improves psychological health, aesthetics and function of patients.

AIM

The present study aimed to investigate patients' satisfaction after orthognathic surgery by means of a satisfaction questionnaire before and after surgery.

MATERIALS AND METHODS

A total of 29 patients was selected (17 women and 12 men), with a mean age of 28 years, randomly selected from a private clinic at Araçatuba - São Paulo by two investigators. Anamnesis and clinical examination were performed. Subjects with facial deformities submitted to orthodontic treatment before and after orthognathic surgery with a minimum post-surgery period of 6 months, answered a satisfaction questionnaire composed of 10 questions regarding dental and facial aesthetics. In this study, the maximum satisfaction score was 10.

RESULTS

Regarding aesthetics, two satisfaction parameters were investigated: dental and facial. For all indices, the average satisfaction was up to score 7.

CONCLUSION

According to the results, it can be concluded that orthognathic surgery has been an effective treatment for dentofacial deformities, aesthetics and functional problems, what was verified by pre and postoperative questionnaire application.

[Patellofemoral arthroplasty: indication, technique and results]

BACKGROUND

Although patellofemoral arthroplasty has been used for more than 30 years, it is still a challenging subject in orthopedics. The reason for this are the complex kinematics of the patellofemoral joint which are influenced by dynamic and static factors. New implant concepts that incorporate multiple coronal and sagittal curvatures and surface controlled inlay implantation show a positive direction in modern patellofemoral arthroplasty.

OBJECTIVES

The purpose of this work is the review of the literature on patellofemoral arthroplasty and the presentation of our own experience.

METHODS

We present indications and surgical techniques of patellofemoral arthroplasty as well as the most important aspects of preoperative evaluation. The patellofemoral joint can be reconstructed using either an inlay or an onlay prosthesis. Both arthroplasty concepts are discussed. Additional pathologies like chronic patellofemoral instabilities due to dysplasia, valgus/varus or rotational malalignment, and soft-tissue alterations are addressed with concomitant procedures.

RESULTS

Both inlay and onlay arthroplasty have demonstrated good functional outcome scores in patients with patellofemoral osteoarthritis. Patients with patellofemoral instability and/or trochlear dysplasia may benefit more from patellofemoral arthroplasty than patients with primary osteoarthritis because not only pain but also secondary pathologies are addressed.

CONCLUSION

Patellofemoral arthroplasty is an effective and safe procedure if the indication criteria are respected and the specific surgical technique is used. However, comparative results on current inlay and onlay prostheses have not been published in the literature to date.

Self Management Behaviors in Rheumatoid Arthritis Patients and Associated Factors in Tehran 2013

INTRODUCTION

Rheumatoid Arthritis (RA) is a systemic, autoimmune and inflammatory disease with an unknown etiology that is associated with progressive joint degeneration, limitation of physical activity and disability. The aim of the study was to evaluate self-management behaviors and their associated factors in RA patients.

MATERIAL & METHOD

This cross-sectional study was performed in 2013 on185 patients in Iran. Data were selected through convenient sampling. The collected data included demographic variables, disease related variables, Arthritis Impact Measurement Scale 2 (AIMS-2SF), and Self-Management Behaviors (SMB). Data were analyzed by SPSS17 using Spearman correlation and logistic regression test.

RESULT

In this study drug management, regular follow-up, and food supplement were used as the most frequently applied SMB and aquatic exercise, diet, massage therapy, and relaxation were the least common SMBs. Age, education, health status, occupation, marital status, sex, DAS28 (Disease Activity Score 28 joints), and PGA (Physician Global Assessment) were significantly related with SMB.

CONCLUSION

The result of the study highlight the influence of demographic variables, health status, and disease related data on SMB. Thus, more studies are required to find factors influencing SMB in order to improve SMB.

A matched-pair comparison of two different locking plates for valgus-producing medial open-wedge high tibial osteotomy: peek-carbon composite plate versus titanium plate

PURPOSE

The first purpose of this study was to compare the clinical and radiographic outcome of two different locking plates used for valgus-producing medial open-wedge high tibial osteotomy (HTO). The second purpose was to histologically evaluate peek-carbon wear for biocompatibility.

METHODS

Twenty-six consecutive patients undergoing open-wedge HTO using the first-generation PEEKPower HTO-Plate® (Group I) were matched with 26 patients after open-wedge HTO with the TomoFix™ plate (Group II). Clinical scores (visual analogue scale for pain, WOMAC, Lysholm score) were obtained preoperatively and at a minimum follow-up of 24 months postoperatively. Fixation stability was evaluated radiographically by comparing the medial proximal tibial angle (MPTA) and tibial slope 2 days after open-wedge HTO and after implant removal. Tissue samples of Group I were collected at the time of implant removal for histologic evaluation.

RESULTS

Implant-related complications occurred in 15 % (n = 4) of Group I and 0 % of Group II. Out of them, 3 implant replacements were excluded from statistical analyses. After a final median follow-up of 25 months (range 24-31), the clinical scores in both groups showed significant improvements compared to preoperatively (visual analogue scale, WOMAC, Lysholm score; p < 0.001), without significant group differences (visual analogue scale, n.s.; WOMAC, n.s.; Lysholm score, n.s.). No significant differences between baseline and follow-up measurements for MPTA and tibial slope were observed within each group (MPTA: Gr. I, n.s.; Gr. II, n.s.; tibial slope: Gr. I, n.s.; Gr. II, n.s.) or between the two groups (MPTA, n.s.; tibial slope, n.s.). In histologic samples, CF PEEK abrasion did not induce inflammation or tissue necrosis.

CONCLUSION

The first-generation PEEKPower HTO-Plate® provided a higher rate of implant-related complications compared to the TomoFix™ plate at a minimum follow-up of 24 months after valgus-producing open-wedge HTO. Therefore, it is not recommended to use the first-generation PEEKPower HTO-Plate® in the clinical practice.

Prospective evaluation of anatomic patellofemoral inlay resurfacing: clinical, radiographic, and sports-related results after 24 months

PURPOSE

To prospectively evaluate the clinical, radiographic, and sports-related outcomes at 24 months after isolated and combined patellofemoral inlay resurfacing (PFIR).

METHODS

Between 2009 and 2010, 29 consecutive patients with patellofemoral osteoarthritis (OA) were treated with the HemiCAP(®) Wave Patellofemoral Resurfacing System (Arthrosurface, Franklin, MA, USA). Based on preoperative findings, patients were divided into two groups: group I, isolated PFIR (n = 20); and group II, combined PFIR with concomitant procedures to address patellofemoral instability, patellofemoral malalignment, and tibiofemoral malalignment (n = 9). Patients were evaluated preoperatively and at 24 months postoperatively. Clinical outcomes included WOMAC, subjective IKDC, Pain VAS, Tegner activity score, and a self-designed sports questionnaire. Kellgren-Lawrence grading was used to assess progression of tibiofemoral OA. The Caton-Deschamps Index was used to assess differences in patellar height.

RESULTS

Twenty-seven patients (93 %) were available for 24-month follow-up. Eighty-one per cent of the patients were either satisfied or very satisfied with the overall outcome. Significant improvements in the WOMAC, subjective IKDC, and Pain VAS were seen in the overall patient cohort and in both subgroups. The median Tegner score and sports frequency showed a significant increase in the overall patient cohort and in group II. The number of sports disciplines increased significantly in both subgroups. No significant progression of tibiofemoral OA or changes in patellar height were observed.

CONCLUSION

Patellofemoral inlay resurfacing is an effective and safe procedure in patients with symptomatic patellofemoral OA. Significant improvements in functional scores and sports activity were found after both isolated and combined procedures.

A study of promethazine hydrochloride and pentazocine intramuscular sedation along with 2 % lidocaine hydrochloride and adrenaline and comparison to placebo along with 2 % lidocaine hydrochloride and adrenaline for surgical extraction of mandibular third molar

BACKGROUND AND OBJECTIVES

The main objective is to study and compare the sedative and analgesic effects of intramuscular injection fortwin-phenergan along with local anesthetic and normal saline placebo along with local anesthetics in mandibular third molar surgery. We also assessed and compared the postoperative experience of the patient in relation to the pain intensity, time to first analgesic taken and total number of analgesics consumed over a period of 48 h in the two groups.

MATERIALS AND METHODS

Patients who came to the Department of Oral and Maxillofacial Surgery, The Regional Dental College; with complaints regarding mandibular third molar were chosen for the treatment. Patients were evaluated using Corah Dental Anxiety Scale (CDAS) and those patients having a score of CDAS 13 and above were selected. Sixty patients were selected out of which 30 patients formed group 1 and another 30 patients group 2. The patients were randomly divided with flip method into group 1 (study group) and or group 2 (controlled group).

RESULTS

Our study results showed that the operating conditions for both the groups at the end of surgery were similar without significant difference. Most of the surgical procedures were graded as excellent and good in both the groups except that difficulty was encountered in two patients from group 1 and one from group 2.

CONCLUSION

It could be concluded that particular drugs do not have much influence on the surgical procedure in our study, but it was found that patients from group 1 were more cooperative as compared to group 2 when difficulty was encountered during the surgical procedure.

Foot orthoses in children with juvenile idiopathic arthritis: a randomised controlled trial

INTRODUCTION

There is limited evidence supporting the podiatric treatment of children with juvenile idiopathic arthritis (JIA). This multicentre randomised controlled trial aimed to determine whether preformed foot orthoses (FOs) impacted on pain and quality of life (QoL) in children with JIA.

METHODS

Eligible children were randomised to receive either 'fitted' FOs with customised chair-side corrections or 'control' FOs made without corrections. Changes in pain and QoL were measured using a visual analogue scale and Paediatric Quality of Life questionnaire, respectively. JIA children were assessed at baseline, 3 months and 6 months.

RESULTS

60 children were recruited. 179 out of a possible 180 assessments (99.4%) were completed. A statistically significant greater difference in pain reduction (baseline - 6 months) was seen between the two groups favouring fitted FOs (p=0.029). The reduction in pain in the fitted FOs group was clinically important (8 mm). Significant differences in QoL favouring fitted FOs were also identified as measured by the children and independently by their parents/carers.

CONCLUSIONS

Fitted FOs may reduce pain and improve QoL in selected children with JIA.

Evaluating the impact of an integrated multidisciplinary head & neck competency-based anatomy & radiology teaching approach in radiation oncology: a prospective cohort study

BACKGROUND

Modern radiation oncology demands a thorough understanding of gross and cross-sectional anatomy for diagnostic and therapeutic applications. Complex anatomic sites present challenges for learners and are not well-addressed in traditional postgraduate curricula. A multidisciplinary team (MDT) based head-and-neck gross and radiologic anatomy program for radiation oncology trainees was developed, piloted, and empirically assessed for efficacy and learning outcomes.

METHODS

Four site-specific MDT head-and-neck seminars were implemented, each involving a MDT delivering didactic and case-based instruction, supplemented by cadaveric presentations. There was no dedicated contouring instruction. Pre- and post-testing were performed to assess knowledge, and ability to apply knowledge to the clinical setting as defined by accuracy of contouring. Paired analyses of knowledge pretests and posttests were performed by Wilcoxon matched-pair signed-rank test.

RESULTS

Fifteen post-graduate trainees participated. A statistically significant (p < 0.001) mean absolute improvement of 4.6 points (17.03%) was observed between knowledge pretest and posttest scores. Contouring accuracy was analyzed quantitatively by comparing spatial overlap of participants' pretest and posttest contours with a gold standard through the dice similarity coefficient. A statistically significant improvement in contouring accuracy was observed for 3 out of 20 anatomical structures. Qualitative and quantitative feedback revealed that participants were more confident at contouring and were enthusiastic towards the seminars.

CONCLUSIONS

MDT seminars were associated with improved knowledge scores and resident satisfaction; however, increased gross and cross-sectional anatomic knowledge did not translate into improvements in contouring accuracy. Further research should evaluate the impact of hands-on contouring sessions in addition to dedicated instructional sessions to develop competencies.

Interpretation for scales of measurement linking with abstract algebra

THE STEVENS CLASSIFICATION OF LEVELS OF MEASUREMENT INVOLVES FOUR TYPES OF SCALE: "Nominal", "Ordinal", "Interval" and "Ratio". This classification has been used widely in medical fields and has accomplished an important role in composition and interpretation of scale. With this classification, levels of measurements appear organized and validated. However, a group theory-like systematization beckons as an alternative because of its logical consistency and unexceptional applicability in the natural sciences but which may offer great advantages in clinical medicine. According to this viewpoint, the Stevens classification is reformulated within an abstract algebra-like scheme; 'Abelian modulo additive group' for "Ordinal scale" accompanied with 'zero', 'Abelian additive group' for "Interval scale", and 'field' for "Ratio scale". Furthermore, a vector-like display arranges a mixture of schemes describing the assessment of patient states. With this vector-like notation, data-mining and data-set combination is possible on a higher abstract structure level based upon a hierarchical-cluster form. Using simple examples, we show that operations acting on the corresponding mixed schemes of this display allow for a sophisticated means of classifying, updating, monitoring, and prognosis, where better data mining/data usage and efficacy is expected.
