Evaluation of Patient's Knowledge of Prevention and Treatment of Burn Injuries

Background

Burn injuries are amongst the most devastating causes of trauma worldwide. Preventive measures can be of great value in decreasing burn incidents. Increasing the knowledge and education of patients is a crucial step in this process.

Methods

In this prospective cross-sectional study, we evaluated 82 patients with burn injuries who were divided into two groups randomly during the 2018 to 2019 at Shahid Motahari Hospital, Tehran, Iran. The first group received an e-Book, and the second group a paperback booklet to read before visiting their primary care. Besides, both groups received a questionnaire on their knowledge of burn injuries and prevention before and after the visit. The e-Book and paperback booklet included basic information about burn injuries and preventive measures. We compared the questionnaire results in both groups before and after reading the e-book and booklet using a paired t-test analysis.

Results

There was a significant improvement in self-reported knowledge of burn prevention (P < 0.05; CI: 95%). Subjects receiving the eBook performed significantly had better post-survey (P < .01, 95% CI), despite equivalent pre-survey scores compared to those receiving the booklet.

Conclusion

Increased use of interactive educational modalities, such as an e-book, can benefit patients with knowledge of their disease and improve the quality of care. These modalities may increase compliance with the physician's recommendations regarding their disease states and treatments.

Determination of Serum Levels of Interleukin-6, Interleukin-8, Interleukin-10, and Tumor Necrosis-Alpha and their Relationship With The Total Body Surface Area in Children

There are few studies on the inflammatory processes and the role of cytokines involved in pediatric burn injuries. The present study aims to measure the serum levels of cytokines and their relationship with the degree of burn injury in children. Within the 48 hours of hospitalization, the serum samples were obtained to measure inflammatory cytokines (interleukin-6, interleukin-8, interleukin-10 [IL-6, IL-8, and IL-10] and tumor necrosis factor-alpha [TNF-α]). The level of all of these cytokine factors was assessed by enzyme-linked immunosorbent assay technique. The mean levels of IL-6, IL-8, IL-10, and TNF-α was 18.15 ± 4.77 pg/ml, 59.54 ± 4.59 pg/ml, 8.41 ± 2.09 pg/ml, and 1.48 ± 0.15 pg/ml, respectively, which were higher than the normal range designated for the healthy pediatrics age group. The levels of TNF-α were higher in patients with sepsis (P = .03) and deceased patients (P = .001). There was a statistically significant difference in the levels of IL-8 in patients with second- (.001) and third-degree (.001) burn injuries in comparison to the first-degree burn injuries, and the level of IL-8 was statistically significantly higher in patients with electrical burn injuries in comparison to scald burn injuries (.01). IL-10 was statistically significantly higher in patients with contact burn injuries in comparison to scald (.001) and flame (.03) burn injuries. Cytokine levels in pediatric burn patients increased after severe burn injuries. There was a significant correlation between the levels of IL-8 and the degree of burn injuries.

Evaluation of Electrical Burn Injuries in Iran: A 7 year retrospective study

Electrical burn injuries can cause devastating and debilitating morbidities and impairments for patients. This cross-sectional descriptive study was performed on electrical burn patients hospitalized from 2014 to 2019 to evaluate electrical burn injuries' epidemiology and characteristics. A total number of 726 patients with the mean age of 31.17 years were evaluated for electrical burn injuries. Mean total burn surface area (TBSA) was 16.61 ± 12.56. Most victims were male (696 cases, 95.7%); and most patients did not have a constant job (n = 458, 63%). Most affected burn sites were hands (28.6%) and upper limbs (27.8%). A total number of 89 (12.2%) patients suffered amputations with the hand fingers (64 cases) as the most common site. Low voltage injuries were more common (n = 649 , 89%). Most incidents happened at the workplace (n =459 , 63%). Comparison of patients with high voltage and low voltage injuries showed significant correlations and statistical difference between these 2 groups regarding TBSA, mean hospital stays, escharectomy, fasciotomy, amputations, debridement, fracture and mortality rate (P = 0.001). Our observation revealed that electrical burn injuries are still significant causes of morbidity and mortality among trauma patients. In contrast to previous studies, low voltage injuries were more common than high voltage ones. We propose improvements in the manufacturing of electrical appliances; paying attention to safety measures will reduce thenumber of incidents. Moreover, training and education play important roles in reducing the number of incidents and mortality rates.

Candidemia in pediatric burn patients: Risk factors and outcomes in a retrospective cohort study

Background and Purpose :

Despite advances in burn care and management, infections are still a major contributor to morbidity and mortality rates in patients with burn injuries. Regarding this, the present study was conducted to investigate the prevalence and importance of candidemia in pediatric burn patients.

Materials and Methods:

Blood samples were collected from the patients and cultured in an automated blood culture system. Candida species were identified using specific culture media. The relationship between candidemia and possible risk factors was evaluated and compared to a control group.

Results:

A total of 71 patients with the mean age of 4.52±3.63 years were included in the study. Blood cultures showed candidemia in 19 (27%) patients. Based on the results, C. albicans was the most common fungus among patients with and without candidemia. The results of statistical analysis also showed that candidemia was significantly correlated with total body surface area (TBSA), mechanical ventilation, duration of total parenteral nutrition, length of intensive care unit (ICU) stay, presence of neutropenia, and R-Baux score (all P≤0.001). In this regard, TBSA, length of ICU stay, R-Baux score, and Candida score were identified as the determinant factors for mortality due to candidemia.

Conclusion:

Candidemia increases the mortality and morbidity rates associated with burn injuries. Prompt diagnostic and prevention measures can reduce the unfortunate outcomes via controlling the possible risk factors.

Adapting Personal Therapies Using a Mobile Application for Tinnitus Rehabilitation: A Preliminary Study

OBJECTIVES

To develop a smartphone application providing sound therapy and cognitive behavioral therapy (CBT) for treating tinnitus and performing a proof-of-concept pilot study evaluating its potential efficacy.

METHODS

An interactive smartphone application available on iOS and Android platforms was developed, which provided an 8-week tinnitus-specific CBT and personalized and frequency-matched sound therapy. Included patients presented to our tertiary clinic between 2017 and 2018, while those waitlisted were regarded as controls. Three surveys were administrated: Tinnitus Handicap Inventory (THI), Generalized Anxiety Disorder 7-item (GAD-7), and Perceived Stress Scale (PSS).

RESULTS

A total of 30 patients enrolled in this study consisting of 20 treatment and 10 control patients and mean age was 55.4 ± 11.6 years. Treatment and control patients had similar age, sex, and pre-enrolment GAD and PSS (all P > .05). Baseline THI scores were also similar between treatment and control cohorts (50.1 ± 21.9 vs 62.0 ± 20.7; P = .15). After 8 weeks, though changes in GAD and PSS scores were similar (P > .05), the treatment group reported a significantly greater improvement in THI scores (17.7 ± 15.8 vs 5.3 ± 10.5, P = .04).

CONCLUSIONS

This pilot study demonstrated potentially promising efficacy of a smartphone-based CBT and sound therapy platform for treating tinnitus and encourages future randomized controlled trials on this treatment modality.

Efficacy of Multi-Modal Migraine Prophylaxis Therapy on Hyperacusis Patients

OBJECTIVES

To evaluate the efficacy of a multi-modal migraine prophylaxis therapy for patients with hyperacusis.

METHODS

In a prospective cohort, patients with hyperacusis were treated with a multi-modal step-wise migraine prophylactic regimen (nortriptyline, verapamil, topiramate, or a combination thereof) as well as lifestyle and dietary modifications. Pre- and post-treatment average loudness discomfort level (LDL), hyperacusis discomfort level measured by a visual analogue scale (VAS), and scores on the modified Khalfa questionnaire for severity of hyperacusis were compared.

RESULTS

Twenty-two of the 25 patients (88%) reported subjective resolution of their symptoms following treatment. Post-treatment audiograms showed significant improvement in average LDL from 81.3 ± 3.2 dB to 86.4 ± 2.6 dB (P < .001), indicating increased sound tolerability. The VAS discomfort level also showed significant improvement from a pre-treatment average of 7.7 ± 1.1 to 3.7 ± 1.6 post-treatment (P < .001). There was also significant improvement in the average total score on modified Khalfa questionnaire (32.2 ± 3.6 vs 22.0 ± 5.7, P < .001).

CONCLUSIONS

The majority of patients with hyperacusis demonstrated symptomatic improvement from migraine prophylaxis therapy, as indicated by self-reported and audiometric measures. Our findings indicate that, for some patients, hyperacusis may share a pathophysiologic basis with migraine disorder and may be successfully managed with multimodal migraine prophylaxis therapy.

The Effect of Mentha Pulegium on Healing of Burn Wound Injuries in Rat

BACKGROUND

Burn is one of the most common injuries and the 4th common cause of trauma globally. This study was designed to evaluate the effect of the Mentha pulegium extract on second degree burn injuries in rats assessing histopathologic and macroscopic.

METHODS

M. Pulegium extract dressings was used as a treatment to deep dermal contact burns in rats, compared with two control groups of vaseline dressing and simple dressing by normal saline. After creating second-degree burn on the dorsum of rats, the treatments were applied for 15 min in three groups. Wound dressings were performed on days 1, 3, 7, 14 and 21^st and at the same time macroscopic assessment was performed using a digital camera and software processing of photos. Pathologic evaluation of skin specimens was undertaken on days 1, 3,7, 14 and 21^st. Wound healing parameters such as epithelialization, angiogenesis, granulation tissue formation, inflammatory cells were compared between these 3 groups.

RESULTS

Application of M. Pulegium extract on second degree burn wounds significantly decreased burn surface area and increased fibroblasts in comparison to simple dressing. There was not any statistically significant relationship between M. Pulegium extract treated group and vaseline treated or simple dressing groups on other wound healing parameters.

CONCLUSION

This study delineated that M. Pulegium extract had a positive effect on healing process of second degree burns.

Evaluating Quality of Life in Patients With Meniere’s Disease Treated as Migraine

Objective:

To evaluate the change in quality of life (QOL) of patients with Meniere’s disease (MD) after treatment with migraine prophylaxis therapy.

Methods:

Patients with definite MD were given the Meniere’s Disease Outcomes Questionnaire–Retrospective (MDOQ-R) after migraine prophylactic therapy to assess QOL. Changes in physical, emotional, and social parameters affected by MD were calculated, along with a global pre- and posttreatment QOL scores.

Results:

The MDOQ-R was given to 27 consecutive patients with definite MD. Patients who had at least an 18-month follow-up were included, resulting in 25 questionnaires. The mean change in QOL score was 25 ± 16 (range, –3 to 55), P = .02. Quality of life was improved in 23 (92%) of the respondents in every metric measured, unchanged in 1 (4%), and poorer in 1 (4%) of patients after migraine prophylaxis treatment.

Conclusions:

Majority of MD patients who had all failed diuretic therapy responded positively to medications used for migraine prophylaxis, as indicated by a significant improvement in QOL. This study may further suggest a correlation between the pathophysiologic basis of disease in MD and vestibular migraine. Patients with MD may be successfully managed with medications intended to treat migraine.

An Analysis of the Open Payment Database in Neurotology

Since the introduction of the Sunshine Act in 2010 and Open Payments Database (OPD) in 2013, a significant amount of data has been collected on physicians and the payments received through ties with pharmaceutical and medical device companies. To date, a study within the field of otology and neurotology using data from the 2015 OPD has not been conducted. As such, we assessed the validity and accuracy of OPD information for otologists and neurotologists (O&Ns). Of the 126 physicians listed as O&Ns in the OPD, 25 were actually general otolaryngologists, and 1 was a cardiologist. In addition, 88 O&Ns were misclassified by the OPD as general otolaryngologists. A total of 1156 payments, summing $1,966,204, were made to O&Ns as a whole, with 646, 507, and 3 payments classified as general, research, and ownership/investment interests, respectively. Analysis of OPD data for O&Ns demonstrates a significant financial relationship between O&N physicians and industry, as well as noteworthy inaccuracies in the OPD that likely affect other subspecialties.

Migraine-Related Aural Fullness: A Potential Clinical Entity

In this case series, we set out to describe the clinical entity of isolated, prolonged aural fullness (AF) and its relationship with migraine. Patients with isolated, persistent AF for 6 months or more were included with all possible etiologies ruled out. Migraine dietary and lifestyle changes and medical migraine prophylactic therapy were prescribed to all. Eleven patients were included (mean age, 52 years). Six (54%) patients fulfilled International Headache Society criteria for migraine with or without aura. Changes in perceived sensation of AF using the visual analog scale and quality of life questionnaires resulted in a statically significant improvement ( P < .001, 95% confidence interval [CI], 4.7 to 6.72, and P < .001, 95% CI, -5.3 to -2.7, respectively). As such, an improvement of isolated, prolonged AF with migraine lifestyle changes and prophylactic treatment may suggest an etiological association between migraine and prolonged aural fullness.

Tympanic Membrane and Ossicular-Sparing Modified Lateral Temporal Bone Resection

A modified lateral temporal bone resection (mLTBR) is a unique technique that spares the tympanic membrane (TM) and ossicles in select patients with squamous cell carcinoma (SCCa). The records of 5 patients with SCCa of the temporal bone with negative frozen-section biopsy at the tympanic annulus were reviewed. The mean follow-up time for the patients was 29.2 months. One patient received postoperative radiation due to cervical nodal extracapsular spread. All patients were recurrence free as of the most recent follow-up (range, 8-50 months). Postoperative audiometry demonstrated an average conductive hearing loss of 9 dB (range, 0-17 dB). The mLTBR with sparing of the TM can be an effective alternative to the traditional lateral temporal bone resection (LTBR) with better hearing results for patients with SCCa involving the bony external auditory canal. In the short term, oncologic results of mLTBR appear equivalent to the LTBR. However, long-term follow-up is needed for >5-year outcomes.

CyberKnife for Treatment of Vestibular Schwannoma: A Meta-analysis

Objectives (1) Perform a meta-analysis of the available data on the outcomes of CyberKnife radiosurgery for treatment of vestibular schwannomas (VSs) in the published English-language literature and (2) evaluate the collective outcomes of CyberKnife treatment with respect to tumor control and hearing preservation. Data Sources A thorough literature search of published English-language articles was performed in the PubMed, Ovid, and Cochrane databases. Review Methods A database search was conducted with the keywords "CyberKnife" and "vestibular schwannoma" or "acoustic neuroma." A total of 25 papers were found and reviewed. Data were extracted for patient demographics, number of patients with neurofibromatosis type 2, pretreatment hearing status, tumor size, margin dose, and follow-up duration. The primary outcome variables evaluated were tumor control and hearing preservation. Results After careful review of the published articles, 11 papers reported data on outcomes of CyberKnife treatment for VS and were included in the analysis, comprising 800 patients studied during 1998 to 2012. The reported mean tumor volume ranged from 0.02 to 19.8 cm³, and the follow-up duration ranged from 6 to 120 months. Margin dose varied from 14 to 25 Gy. The collective mean tumor control rate was 96.3% (95% CI: 94.0%-98.5%). The collective hearing preservation rate was 79.1% (95% CI: 71.0%-87.3%) in 427 patients with measurable hearing. Conclusion Clinical data on outcomes of CyberKnife radiosurgery for treatment of VSs are sparse and primarily limited to single-institution analyses, with considerable variation in tumor volume and follow-up time. This meta-analysis not only provides an in-depth analysis of available data in the literature but also reviews reported outcomes and complications.

Use of interactive iBooks for patient education in otology

INTRODUCTION

Physicians in the ambulatory setting face challenges in adequately educating patients in a brief office encounter.

OBJECTIVE

To evaluate the efficacy of an iPad-based interactive educational module (iBook) in various otologic pathologies.

METHODS

Patients presenting with symptoms of tinnitus, dizziness, hearing loss, or cochlear implant evaluation were included. In total, 44 patients received the iBook and 22 patients served as controls. Prior to viewing the iBook, patients completed a pre-survey to assess baseline knowledge. After viewing the iBook, patients completed a post-survey to assess changes in perception and knowledge of their disease. Results were compared to that of the control group who did not receive iBook supplementation prior to being seen by the physician.

RESULTS

Paired t-test analysis showed significant improvements (p<0.01) in both self-reported perception and concrete understanding in various concepts when compared to pre-iBook results. This was further compared to the control group, which showed a significant gain in factual knowledge (p=0.02).

CONCLUSION

Patients who viewed the iBook, personalized to their diagnosis, displayed significantly improved understanding of their condition. Increased use of interactive educational modalities, such as the iBook, can be of benefit to an otologic practice in improving patient education and satisfaction.

Dosimetric Analysis of Neural and Vascular Structures in Skull Base Tumors Treated with Stereotactic Radiosurgery

Objective To examine the relationship between the prescribed target dose and the dose to healthy neurovascular structures in patients with vestibular schwannomas treated with stereotactic radiosurgery (SRS). Study Design Case series with chart review. Setting SRS center from 2011 to 2013. Subjects Twenty patients with vestibular schwannomas treated at the center from 2011 to 2013. Methods Twenty patients with vestibular schwannomas were included. The average radiation dose delivered to healthy neurovascular structures (eg, carotid artery, basilar artery, facial nerve, trigeminal nerve, and cochlea) was analyzed. Results Twenty patients with vestibular schwannomas who were treated with fused computed tomography/magnetic resonance imaging-guided SRS were included in the study. The prescribed dose ranged from 10.58 to 17.40 Gy over 1 to 3 hypofractions to cover 95% of the target tumor volume. The mean dose to the carotid artery was 5.66 Gy (95% confidence interval [CI], 4.53-6.80 Gy), anterior inferior cerebellar artery was 8.70 Gy (95% CI, 4.54-12.86 Gy), intratemporal facial nerve was 3.76 Gy (95% CI, 3.04-4.08 Gy), trigeminal nerve was 5.21 Gy (95% CI, 3.31-7.11 Gy), and the cochlea was 8.70 Gy (95% CI, 7.81-9.59 Gy). Conclusions SRS for certain vestibular schwannomas can expose the anterior inferior cerebellar artery (AICA) and carotid artery to radiation doses that can potentially initiate atherosclerotic processes. The higher doses to the AICA and carotid artery correlated with increasing tumor volume. The dose delivered to other structures such as the cochlea and intratemporal facial nerve appears to be lower and much less likely to cause immediate complications when shielded.

Wrong-Site Surgery in California, 2007-2014

Objective The implementation of a universal surgical safety protocol in 2004 was intended to minimize the prevalence of wrong-site surgery (WSS). However, complete elimination of WSS in the operating room continues to be a challenge. The purpose of this study is to evaluate the prevalence and etiology of WSS in the state of California. Study Design A retrospective study of all WSS reports investigated by the California Department of Public Health between 2007 and 2014. Methods Prevalence of overall and specialty-specific WSS, causative factors, and recommendations on further improvement are discussed. Results A total of 95 cases resulted in incident reports to the California Department of Public Health and were included in our study. The most common errors were operating on the wrong side of the patient's body (n = 60, 62%), performing the wrong procedure (n = 21, 21%), operating on the wrong body part (n = 12, 12%), and operating on the wrong patient (n = 2, 2%). WSS was most prevalent in orthopedic surgery (n = 33, 35%), followed by general surgery (n = 26, 27%) and neurosurgery (n = 16, 17%). All 3 otolaryngology WSS cases in California are associated with the ear. Conclusion WSS continues to surface despite national efforts to decrease its prevalence. Future research could establish best practices to avoid these "never events" in otolaryngology and other surgical specialties.

Smartphone-Enabled Otoscopy in Neurotology/Otology

Objective

A smartphone-enabled otoscope (SEO) can capture tympanic membrane (TM) images. We sought to compare a SEO to microscopic otoscopy in the detection and evaluation of TM pathology in an otology/neurotology practice.

Study Design

Prospective single-site study in adults presenting over a 3-month period.

Setting

Neurotology clinic within a tertiary care academic medical center.

Subjects and Methods

Following consent, 57 patients underwent a medical and microscopic ear examination. Afterward, clinicians photographed bilateral TMs using a SEO. A second “blinded” neurotologist received a SEO-acquired image of each TM and a brief patient history. Our primary end point was identification of TM pathology (or lack thereof) and the blinded neurotologists’ corresponding diagnosis. Secondary end points included patient-reported SEO comfort levels.

Results

A single SEO-acquired TM image and brief patient history resulted in correct diagnosis of 96% (23/24) of normal TMs and identification of 100% (33/33) of microscope-confirmed abnormal TMs. When pathology was identified by the “blinded” physician, the diagnosis was identical to that made by the primary treating physician 82% (27/33) of the time. On patient surveys, 93% (53/57) of patients felt “very comfortable” with SEO utilization, and 88% (50/57) reported viewing acquired images was “very useful” in understanding their condition.

Conclusion

A SEO is 96% specific in identifying normal TMs and 100% sensitive in identifying pathology. Its 97% positive predictive value and small false-positive rate makes it a useful screening tool. Furthermore, patients are receptive to this technology and felt comfortable with its utilization in a health care or possible telemedicine setting.

Management of mal de debarquement syndrome as vestibular migraines

OBJECTIVE

Mal de debarquement syndrome (MdDS) is a balance disorder that typically starts after an extended exposure to passive motion, such as a boat or plane ride. Management is typically supportive (e.g. physical therapy), and symptoms that persist beyond 6 months have been described as unlikely to remit. This study was conducted to evaluate the response of patients with MdDS to management with migraine prophylaxis, including lifestyle changes and medical therapy.

STUDY DESIGN

Prospective review.

SETTING

Ambulatory setting at a tertiary care medical center.

METHODS

Clinical history, detailed questionnaires, and audiograms were used to diagnose patients with MdDS. Those patients with the diagnosis of the MdDS were placed on our institutional vestibular migraine management protocol. Treatment response was assessed with a quality-of-life (QOL) survey and visual analog scale.

RESULTS

Fifteen patients were diagnosed with MdDS, with a predominance of females (73%) and a mean age of 50 ± 13 years. Eleven patients (73%) responded well to management with a vestibular migraine protocol, which included lifestyle changes, as well as pharmacotherapy with verapamil, nortriptyline, topiramate, or a combination thereof. In comparison, a retrospective control group of 17 patients demonstrated a lower rate of improvement when treated with vestibular rehabilitation and physical therapy.

CONCLUSION

Management of MdDS as vestibular migraine can improve patients' symptoms and increase the QOL. Nearly all the patients suffering from MdDS had a personal or family history of migraine headaches or had signs or symptoms suggestive of atypical migraine.

Auricular Split-Thickness Skin Graft for Ear Canal Coverage

Split-thickness skin graft (STSG) continues to be the preferred means of external auditory canal (EAC) reconstruction. We thus sought to describe our experience using skin from the posterior aspect of the auricle (SPAA) as a donor site in EAC reconstruction. Grafts were, on average, 5 × 10 mm in size and obtained with a No. 10 blade after tumescence injection. The cases of 39 patients who underwent 41 procedures were retrospectively reviewed. Of the 38 patients with both 3- and 6-month follow-ups, no postoperative stenosis or bony exposure occurred. STSG from the SPAA can be a good option in EAC reconstruction. Total EAC/tympanic membrane coverage can be obtained with STSG from the SPAA.

A Historical Recount: Discovering Menière's Disease and Its Association With Migraine Headaches

OBJECTIVES

In evaluating the historical context of the first description of Menière's disease, its association with migraine headaches is compelling. We have outlined the events and observations of Prosper Menière, which led him to establish a link between migraine headaches and his eponymous disease.

STUDY DESIGN

Prosper Menière's original French writings were translated by our group and used to recount his observations and thoughts. Miles Atkinson's English translations were used as a reference. Additional otological texts of the era were also reviewed as it relates to Menière's disease.

METHODS

Prosper Menière wrote a series of four articles 1 year before his death. In one of these articles, he makes references to migraine headaches on several occasions. These original writings were analyzed, and the physical findings he described were interpreted based on their relation to migraine headaches.

RESULTS

The passages in his published articles provide historical insight into Menière's observations. His writings describe in detail symptoms of migraine headaches uniquely evident in his patient population. Through his observations, he recognized that in addition to exhibiting symptoms of tinnitus, hearing loss and vertigo his patients also suffered from migraine headaches.

CONCLUSIONS

Although his colleagues discounted Menière's theory concerning migraine headaches, he continued to make deductive inferences and publish his findings, leading to the association of migraine headaches and Menière's disease. Today, this association continues to be debated, adding to Prosper Menière's legacy.

Autologous Cricoid Cartilage as a Graft for Airway Reconstruction in an Emergent Technique - A Case Report

INTRODUCTION

Laryngotracheal stenosis can be caused after traumatic injuries to the neck from the subglottic larynx to the trachea. Patients with laryngotracheal stenosis often need a tracheotomy and occasionally may become tracheotomy dependent. Different procedures have been described for the management of these lesions. Management options include techniques of endoscopic dilation, laser resection, laryngo-fissure, and an innovative array of plastic reconstructions with or without the use of stents.

CASE REPORT

This paper presents airway reconstruction in a young patient with severe subglottic stenosis due to a blunt trauma to the neck, who was treated using particles of an autologous fractured cricoid cartilage as the source for airway augmentation. An incision was made in the anterior midline of the cricoid lamina and deepened through the scar tissue to the posterior cricoid lamina. Then two lateral incisions (right & left) were made in the cricoid lamina and fractured cartilage particles and the scar tissue were removed via these two lateral incisions. The mucosal lining at the right and left of the midline incision, after debulking, were sutured to a lateral position. Thereafter three cartilage particles were used to reconstruct the anterior cricoid lamina and augment the lumen.

CONCLUSION

It is worth to mention that an autologus cartilage graft can be used for certain cases with traumatic airway stenosis. Further follow up and more patients are needed to approve this method of reconstructive surgery in emergent situations.

Serum 25-Hydroxyvitamin D Levels in Pediatric Burn Patients

Background

Previous studies have implicated the important and active role of vitamin D in the immune system.

Objectives

The aim of this study was to evaluate serum levels of 25-hydroxyvitamin D in children with burn injuries.

Materials and Methods

In this cross-sectional study, 118 patients with various degrees of burn injuries were enrolled. A checklist consisting of demographic data, total body surface area (TBSA) affected by burn, degree of burn, serum level of 25(OH)D, total protein, albumin, electrolytes, and parathyroid hormone was recorded for each patient.

Results

Sixty-eight (57.6%) males and 50 (42.4%) females with a mean age of 4.04 years (SD = 3.04) were evaluated. The mean level of 25(OH)D was 14.58 ng/mL (SD = 6.94). Levels of 25(OH)D in four (3.39%) cases were higher than 30 ng/mL, while 95 (81.35%) cases had levels lower than 20 ng/mL, and 19 (16.10%) cases had levels of 21 - 30 ng/mL. The level of 25(OH)D was below recommended levels in 96.61% of cases, while 81.34% had vitamin D deficiency and 16.1% had insufficiency. We found a significant correlation between vitamin 25(OH)D and total protein, albumin, and total and ionized calcium (P < 0.001). There was also a significant negative correlation between 25(OH)D and TBSA affected by burn (P = 0.001).

Conclusions

The levels of 25(OH)D in children suffering from severe burns were low. Supplementation might be useful in patients with very low levels of serum vitamin D.

Congenital anomalies of the incudostapedial joint

OBJECTIVE

To describe congenital anomalies of the incudostapedial joint (ISJ) and to discuss the possible unique embryogenesis of the ISJ based on the two anomalies that were encountered.

SETTING

Tertiary care medical center.

SUBJECTS AND METHODS

Retrospective review of the medical records of all patients with ISJ anomalies.

RESULTS

Four patients presented with congenital hearing loss. Upon further workup, we observed a preserved incudostapedial joint (ISJ) with deficiencies of the incus and stapes in three cases. Our fourth case demonstrated the inverse pattern of the congenital anomalies in which the ISJ was missing with an intact proximal incus and stapes crura. Three patients opted for surgical intervention with improvement in hearing. One case preferred hearing amplification over surgery.

CONCLUSION

Isolated ISJ malformations are uncommon potential causes of congenital conductive hearing loss. Although numerous patterns of ossicular anomalies have been reported in the literature, our case series is the first to demonstrate both the absence of the ISJ in one patient and the presence of the ISJ in the presence of missing stapes crura and incus body in other patients. Though limited by the small number of cases, the inverse relationship of the single case compared to the three other cases, suggests a possible independent embryological development pathway for the ISJ. Therefore, an embryological explanation of the defects should be considered. Additionally, surgical intervention can improve hearing outcomes for patients with isolated ISJ anomalies.

Loudness and acoustic parameters of popular children's toys

OBJECTIVE

This project was conducted to evaluate the loudness and acoustic parameters of toys designed for children. In addition, we investigated whether occluding the toys' speaker with tape would result in a significant loudness reduction; thereby potentially reducing the risk of noise induced hearing loss.

METHODS

Twenty-six toys were selected after an initial screening at two national retailers. Noise amplitudes at 0.25, 0.5, 1, 2, 4, and 8kHz were measured using a digital sound level meter at a distance of 0 and 30cm. The toys' speakers were then occluded using adhesive tape and the same acoustic parameters were re-measured.

RESULTS

Mean maximum noise amplitude of the toys at 0cm and 30cm was 104dBA (range, 97-125dBA) and 76dBA (range, 67-86dBA), respectively. Mean maximum noise amplitude after occlusion at 0cm and 30cm distances was 88dBA (range, 73-110dBA) and 66dBA (range, 55-82dBA), respectively, with a p-value <0.001.

CONCLUSIONS

Proper use of the loudest toys at a distant of 30cm between the speaker and the child's ear will likely not pose a risk of noise-induced hearing loss. However, since most toys are used at closer distances, use of adhesive tape is recommended as an effective modification to decrease the risk of hearing loss.

Prevalence of beta lactamase producing species of pseudomonas and acinetobacter in pediatric burn patients

Burn wound infection is a major cause of morbidity and mortality in burn victims. Pseudomonas and Acinetobacter species are among the most common organisms complicating burn wounds. Presence of extended spectrum ß-lactamase (ESBL) and metallo-ß-lactamase (MBL) genes plays an important role in spreading ß-lactam resistant strains of these organisms and is a serious condition in the treatment of the affected patients. As a result, we aimed to determine the prevalence of SHV, TEM, PER and VIM ß-lactamases in Pseudomonas and Acinetobacter species isolates from burn wound swabs of children with burn injury. In this descriptive observational study, 107 Pseudomonas and Acinetobacter isolates collected from burn patients were subjected to PCR assay. Using PCR method and DNA sequencing, the existence of SHV-, TEM-, PER- and VIM-type ß-lactamase encoding genes were determined. Out of the 107 Pseudomonas and Acinetobacter isolates, 66 (77.6%) were ESBL positive, 26.2% were positive for SHV gene, 37.4% were positive for TEM gene, 14% were positive for PER gene and 15.9% of them harbored VIM gene. More than half of the Pseudomonas and Acinetobacter strains in our pediatric burn unit harbor ß-lactamase encoding genes that make them resistant to a wide range of ß-lactam antibiotics. Consequently, it is suggested to choose an appropriate antibiotic regimen based on the antibiogram pattern of the strains.

Effect of Heparin on Post-Operative Adhesion in Flexor Tendon Surgery of the Hand

Flexor tendon laceration is a common hand injury. Timely and correct diagnosis of this defect is an important factor for restoring hand function. Post-operative adhesion is a frequent problem after tendon repair and its prevention is difficult in some types of tendon lacerations. There have been some controversial studies on the positive effect of some materials and substances on prevention of these adhesions. This study aims to evaluate effects of the Heparin in postoperative tendon adhesions. In this clinical trial, 100 patients with laceration of flexor tendons in zone II of the hand were enrolled. The patients were randomly divided into two groups. In the first group, 0.5 cc Heparin (5000 IU/cc) was injected into each tendon ends before tendon repair. In the control group, repair was carried out without any heparin injection. After 3 months the total active range of motion (TAROM), mean extension gap (MEG) and mean flexion gap (MFG) were measured and compared between these two groups. The TAROM and MEGs were not significantly different between two groups; but MFGs were significantly better in Heparin treated group (P < 0.02). However rupture rate was significantly higher in heparin treated group (P = 0.003). Heparin may improve the tendons function and reduce the postoperative adhesions in zone II of the hand; however there is a significant risk of tendon rupture.

Migraine features in patients with Meniere's disease

OBJECTIVES/HYPOTHESIS

To better understand the features of migraine in Meniere's disease (MD).

STUDY DESIGN

Retrospective review of prospectively obtained surveys in an outpatient clinic of a tertiary medical center.

METHODS

Detailed questionnaires on headaches and dizziness were given to consecutive patients presenting with dizziness. The responses were verified by the clinician with the patient. The data, in addition to the clinical history and audiogram, were used to diagnose patients with migraine headaches and MD using criteria set by the International Headache Society (IHS) and the American Academy of Otolaryngology-Head and Neck Surgery, respectively. The prevalence of migraine-like symptoms in those patients with MD, who did not fit the diagnostic criteria for migraine, was evaluated.

RESULTS

Thirty-seven patients with definite MD were included. There was a predominance of females (female/male:26/11). Mean age of patients was 52 ± 14 years. Nineteen patients (51%) had migraine headaches. Fifteen patients fulfilled the criteria for definite vestibular migraine. Of those who did not fulfill the IHS migraine criteria, a majority had characteristics such as a family history of migraine, visual motion sensitivity, or lifelong motion sickness that were highly suggestive of a migraine disorder.

CONCLUSIONS

A majority of patients with MD have migraine headaches as defined by the IHS. Sensitivity to visual motion, light and sound, head motion, smells, weather changes, or medication was present in 95% of all patients with definite MD and 82% of non-IHS migraine MD patients. This may suggest that MD may be an atypical variant of migraine.

Vestibular Schwannoma Excision in Sporadic versus Neurofibromatosis Type 2 Populations

OBJECTIVE

To understand the differences in characteristics of neurofibromatosis type 2 (NF2) and sporadic patients with surgically excised vestibular schwannomas in the state of California.

STUDY DESIGN

Cross-sectional.

SETTING, SUBJECTS, AND METHODS

The records of all patients who underwent vestibular schwannoma excision between 1997 and 2011 were extracted from the California Hospital Inpatient Discharge Databases (CHIDD). NF2 cases were identified using ICD-9-CM diagnosis code 237.72, neurofibromatosis, type 2. All other cases were recoded as sporadic. Trends in total number and population-adjusted rates (per 1 million California residents) of surgery, demographics, hospital case volume, state of residency, complications, length of stay, total charges, expected source of payment, and disposition were examined.

RESULTS

Vestibular schwannoma (VS) excision was performed on 7017 patients, of which 464 patients (6.6%) had NF2. The population-adjusted surgery rate declined from 11.8 to 6.2 (P < .001) for sporadic cases and from 0.3 to 0.2 (P = .01) for NF2 cases over the study period. NF2 was associated with younger age (mean, 32.9 vs 51.3), higher rate of other complications (8.8% vs 4.4%) and facial nerve complications (32.3% vs 16.8%), higher total charges (median $70,106 vs $46,395), longer stay (median 5 vs 4), and high volume hospitals (80.4% vs 48.8%) (all P < .001).

CONCLUSION

The surgery rates for vestibular schwannoma excision for both sporadic and NF2 patients have declined, but the decline is more prominent for sporadic cases. NF2 patients tend to be younger and have a longer hospitalization and possibly higher corresponding hospital charges compared to patients with sporadic VS.

Effect of green tea on the second degree burn wounds in rats

Background:

Various studies indicate that the green tea has anti-inflammatory and anti-oxidative properties. Moreover, a few studies have been carried out that demonstrate beneficial effects of green tea on burned patients.

Materials and Methods:

In this study, green tea, Vaseline, and silver sulfadiazine dressings were used as first-aid treatment to deep dermal contact burns in rats, compared with a control of nothing. After creating second-degree burn on the dorsum of rats, the treatments were applied for 15 min in four groups. Wound dressing changes were daily. Macroscopic study was performed on days 1, 3, 7, and 14 by using a digital camera and software processing of photos. Microscopic examination was done by pathologic evaluation of skin specimens on day 14.

Results:

We observed that green tea usage significantly decreased burn size in comparison to the control group (P = 0.004).

Conclusion:

Green tea is effective on healing process of second degree burn wounds.

Inflammatory pseudotumour of the temporomandibular joint

Head and neck inflammatory pseudotumors (IPs) are rare, idiopathic, non-neoplastic lesions that most commonly affect the orbit, but may involve other areas such as the larynx, oropharynx, paranasal sinuses, and meninges. We report the case of a 55-year-old man who presented with progressive left-sided hearing loss, aural fullness, and otalgia. Computed tomography and magnetic resonance imaging (MRI) detected a soft-tissue mass in the left temporomandibular joint (TMJ). Histopathologic examination showed overlying squamous epithelium with hyperkeratosis, parakeratosis, subepithelial fibrosis, and chronic inflammatory infiltrate, which were consistent with an IP. Radiologic images and MRI indicated an ill-defined soft tissue involving the roof and posterior aspect of the TMJ, extending into the anterior external auditory canal. Our case was treated with a 2-week course of high dose prednisone (1 mg/kg) and a 2-week taper with resolution of symptoms. Two years after treatment, the patient shows no evidence of recurrence on MRI.

Electrical burn injury: a five-year survey of 682 patients

Background:

Electrical burn is less prevalent in comparison to other forms of burn injuries, however this type of injury is considered as one of the most devastating due to high morbidity and mortality. Understanding the epidemiologic pattern of electrical burns helps determine the contributing factors leading to this type of injury.

Objectives:

Epidemiologic studies on electrical burn are scarce in Iran. This study was conducted to evaluate electrical burn injury at our center.

Materials and Methods:

Demographic data, etiology, burn percentage and other measures related to electrical burn injury of 682 electrical burn patients treated from 2007 to 2011 were collected and analyzed.

Results:

We assessed 682 electrical burn patients (~10.8% of all burn patients); the mean age was 29.4 years and 97.8% were males. The mean hospital stay was 18.5 days and the mean burn extent was 14.43%. Severe morbidities caused 17 (2.5%) deaths. Amputation was performed in 162 cases. The most common amputation site was the fingers (35%). Most victims were workers and employees and 68.5% of electrical burns occurred at their workplace; 72% of electrical burns were due to high voltage electrical current (more than 1000 V). There was a correlation between voltage and amputation (P = 0.001) and also between voltage and fasciotomy (P = 0.033), but there was no correlation between voltage and mortality (P = 0.131)

Conclusions:

Electrical burn injuries are still amongst the highest accident-related morbidities and mortalities. Educating the population about the dangers and hazards associated with improper use of electrical devices and instruments is imperative.

Radiosurgical Trends for Treatment of Vestibular Schwannomas in the United States

Objectives:

(1) Analyze the recent trends in radiosurgery for vestibular schwannomas (VS). (2) Determine the number of VS treated with radiosurgery since 1990 in the United States.

Methods:

Large databases were obtained by contacting the manufacturers of the 2 main radiosurgical machines used to treat VS in the United States. Analysis of de-identified data from Leksell Gamma Knife reporting was carried out to investigate the treatment trends for VS. The main variable investigated was the number of VS treated by radiosurgery in the United States. Extrapolations were made to the available data to estimate the trends of radiosurgical treatment.

Results:

The number of VS treated by radiosurgery has been increasing. In the US, radiosurgery for treatment of VS was approximately 150 to 200 per year from 1991 to 1993. However, VS cases treated by radiosurgery were approximately 1520 and 1490 in 2011 and 2012, respectively. This indicates an approximate average annual rate of increase of about 4.7% (SD: 8.6%). Currently, treatment of VS accounts for 8.4% of all head and neck radiosurgical procedures in the United States. Since 1991, the approximate number of patients undergoing radiosurgery for VS is 16,000 in the United States and 70,000 worldwide.

Conclusions:

The current study shows a possible changing trend in the management of VS. Our findings support the conclusion of other studies that suggest a growing number of patients are opting to receive radiosurgical treatment. Additionally, the data highlights the growing population of VS treated with radiosurgery.

Transcanal Micro-osteotome Technique for Excision of Exostoses

Objectives:

This study was conducted to evaluate the outcomes and complications of transcanal excision of exostoses using micro-osteotomes without a post-auricular incision or the use of the drill.

Methods:

A retrospective chart review of patients undergoing exostoses excision by the senior author from January 2007 to January 2014 was carried out. All patients underwent surgical removal of the exostoses using a 1 or 2 mm micro-osteotome. Patients were followed postoperatively and complications were evaluated.

Results:

One-hundred-thirty-eight ears in 106 patients were treated for exostosis. Average age of patients was 43 ± 16 year old. Of these, 99 were males (93%) and 7 were females (7%). A majority of the patients had 90% to 100% obstruction of the ear canal. Complete ear canal healing was seen in 80% of patients by 3 weeks. All but one patient had healed by 6 weeks postoperatively. There were 9 (6.5%) slit tympanic membrane perforations that all healed. One patient had an anterior canal mobilization which required Xeroform packing for 3 weeks for stabilization. There was no postoperative vertigo, facial paresis, conductive/sensorineural hearing loss, soft tissue stenoses, and no skin grafting was required.

Conclusions:

A transcanal approach using micro-osteotomes for removing exostoses is feasible. The transcanal approach afforded shorter healing times than the post-auricular approach as reported in the literature. Patients with 100% obstruction can have this procedure performed with no significant increase in morbidity.

Colonization of Mycoplasma hominis and Ureaplasma urealyticum in pregnant women and their transmission to offspring

BACKGROUND AND OBJECTIVES

Mycoplasma hominis and Ureaplasma urealyticum are important opportunistic pathogens that cause urogenital infections and accelerated newborn delivery in pregnant women. Moreover genital mycoplasmas have been implicated in different neonatal diseases such as pneumonia, sepsis and meningitis. This study was conducted to find out the prevalence and transmission rate of these two organisms in pregnant women and their neonates.

MATERIALS AND METHODS

Nasotracheal and pharyngeal specimens of 165 newborns hospitalized at Neonatal Intensive Care Unit (NICU) of Rasoul Akram Hospital (during 2010 - 2011) were assessed by PCR to detect M. hominis and U. urealyticum. Moreover, PCR of vaginal specimens from their mothers were obtained to determine the prevalence of these organisms in pregnant women and rate of transmission to their newborns. Data were analyzed using SPSS software.

RESULTS

Totally, the results of PCR were positive in 33 newborns (20%). Vaginal colonization among the mothers was found to be 15% (25/165) for U. urealyticum and 15% (25/165) for M. hominis. The transmission rate to their infants was 72% and 60% for U. urealyticum and M. hominis, respectively.

CONCLUSION

These data indicate that vertical transmission of mycoplasma and ureaplasma are prevalent in newborns. Since these organisms cause serious infections in neonates, it would be better to perform screening tests in pregnant women before the delivery in order to prevent transmission to neonates and consequent infections and morbidities among them.

Mortality and morbidity of fireworks-related burns on the annual last wednesday of the year festival (charshanbeh soori) in iran: an 11-year study

BACKGROUND

Management of firework-related injuries is costly for the patient, society, and government.

OBJECTIVES

Evaluating effective factors yielding to such injuries may lead to better management of patients and decreased costs and morbidities.

PATIENTS AND MATERIALS

This retrospective cross-sectional study was performed on burn patients referred to Shahid Motahari Burns Hospital on Charshanbeh Soori day festival during the period extending from March 2000 to March 2011 (11 days in an 11-year period). Demographic data, causes of burn injury, severity, and affected body parts were recorded. Data were analyzed using SPSS version 16.

RESULTS

There were164 patients in the study with a mean age of 18.34 ± 9.31 years; 87% (145/164) were male. Homemade grenades were the most frequent cause of injury. Hand injury was reported in 56% (92/164) of the cases. Amputation was executed in 7 (4.3%) cases, and 6 (3.7%) patients died due to severe burn injuries and facial damage.

CONCLUSIONS

Fireworks- related injuries during Charshanbeh Soori ceremony causes significant morbidities and damage to different body parts (especially upper limbs and face), and some of these injuries will lead to life time disabilities, amputations, and even death. As most of the injured patients are young teenagers and children, special consideration must be taken into account to prevent long term morbidities.

Serum immunoglobulin levels in pediatric burn patients

Infections remain the leading cause of death in burn patients. Immune responses play an important role in patient's defense mechanism against infection and decreasing morbidity and mortality associated with burn. Our goal was to determine serum immunoglobulin levels in pediatric burn patients in order to understand role of humoral immune defense in these patients. During this analytic cross sectional study from January 2011 to February 2012, all patients with burn and younger than 6 years old that were referred to Shahid Motahari burn and reconstruction center were enrolled. Patients had no inhalation injury or sepsis. Immunoglobulin levels were measured once on 3-5 days after burn. The burn size in 12 patients (24%) was less than 30%, in 30 patients (60%) were between 30% and 50% and in the remained 8 patients (16%) were more than 50%. In 45 patients (90%) depth and severity of burn were 2nd degree (superficial and deep) and in the remaining 5 patients (10%), it was 3rd or 4th degree. In 28 (56%), 1 (2%), 3 (6%), 35 (70%), 48 (96%), 19 (38%) and 6 (12%) patients IgG, IgM, IgA, IgG1, IgG2, IgG3 and IgG4 were lower than normal values, respectively. No significant correlation was seen between burn size (TBSA) and value of immunoglobulin (P>0.05). Although the drop in the serum concentration of immunoglobulins is irrespective to the burn size, more severe burn is associated with more decrease in the serum levels of IgA, IgM, IgG and its subclasses. However, further studies are needed to provide complementary data on this issue.

The anticipation and inheritance pattern of c.487A>G mutation in the GJB2 gene

Mutations in the GJB2 gene are the most common causes of hereditary hearing loss. This study reveals some facts about the inheritance pattern of M163V in the GJB2 gene. This study was performed on two different families with non-syndromic hearing loss. We screened the GJB2 coding region with direct sequencing. There was a substitution of A to G in exon 2 at nucleotide 487 (M163V). This mutation was heterozygous in fathers and children while mothers were normal. Fathers of both families showed late onset hearing impairment, but there was early onset hearing loss in the children, which was more severe compared to the fathers. M163V has been reported as an unknown heterozygous mutation that leads to failure of the homotypic junctional channel formation. Another mutation in this codon is M163L, with an autosomal dominant inheritance, which impairs trafficking through the plasma membrane, resulting in cell death. Assessment of the familial pedigree has revealed anticipation in phenotype and autosomal dominant inheritance. These data in addition to the high conservation of methionine residue in mammalian species suggest that M163V is inherited with an autosomal dominant pattern. Therefore, the risk of inheritance will increase. Genetic counselors and otologists should prioritize the evaluation and prevention of this disorder in patients.

Evaluation of diagnostic values of photodynamic diagnosis in identifying the dermal and mucosal squamous cell carcinoma

OBJECTIVES

We conducted a study to determine and compare the efficacy of pathology and photodynamic studies in establishing diagnosis of malignant dermal and mucosal lesions.

METHODS AND PATIENTS

This descriptive cross-sectional study was performed on 40 patients suspected of SCC (squamous cell carcinoma). First, in PDD (photodynamic diagnosis) photosensitizing agent was applied to the lesion, and after 4-5h the fluorescence spectrum was detected by laser radiation. Based on fluorescence intensity, normal area was differentiated from malignant area. Also, biopsy samples from these suspected areas were sent to pathology simultaneously. Data were analyzed with SPSS v.16. The distribution of nominal variables was compared using the Chi-square test. Diagnostic index for photodynamic diagnosis were calculated. A two-sided p-value<0.05 was considered to be statistically significant.

RESULTS

In 27 cases (90%), results of pathology and photodynamic studies similarly showed malignancy. In 8 cases (80%), results of pathology and photodynamic studies similarly showed non-malignant lesion. But in five cases (12.5%) the results of pathology and photodynamic studies were not the same. This difference was not statistically significant showed by the Chi-square test analysis (p-value>0.05). A sensitivity of 90%, specificity of 80%, accuracy of 87.5%, positive predictive value (PPV) of 93%, negative predictive value (NPV) of 72%, positive likelihood ratio (PLR) of 4.5, negative likelihood ratio(NLR) of 0.125 were found in diagnosing SCC for photodynamic studies.

CONCLUSION

Photodynamic diagnosis is a useful non-invasive initial step in the diagnostic work-up of patients with suspected malignant lesions (SCC). In this work we have studied 40 SCC suspicious patients using PDD method and successfully carried out 27 cases as malignant all of which were matching with pathologic results. This outcome can prove both accuracy and reliability of PDD method for detecting SCC lesions on head and neck regions. Also PDD can fully demarcate the lesion peripheries less invasively as well as preserving much more time and effort. Although PDD method is a bit more expensive that biopsy and pathology but great advantages can easily cover this issue. We recommend PDD as a useful easy technique to visualize and detect the extension of the tumor preoperatively.

Effect of shift work on patient-doctor relationship in emergency department

BACKGROUND

This study aimed to find effect of shift work on patient-doctor relationship in Emergency Department.

METHODS

In a prospective cross-sectional study, 352 patients (mean age of 44 ± 17 years, 131 females and 221 males) referred to the emergency department of Rasoul-Akram hospital were enrolled in the study. The patient-doctor relationship questionnaire (PDRQ) was asked to be filled by patients. The questionnaires contained 9 items and the appropriateness of the statements was simplified to a scale of 1 (not at all) through 5 (totally).

RESULTS

Comparing three shift works, the highest PDRQ score was for morning (27.1 ± 5.5) and the lowest value was for afternoon shift (23.8 ± 5.3). PDRQ score for night shift was 25.1 ± 6.9 (p = 0.002).

CONCLUSIONS

The results of this study encouraged that patients' satisfaction of relationship with doctors was the lowest in the afternoon and it may be better to implement some strategies to reduce residents' workloads and increase quality of works in the afternoon shifts.
