Management of upper and lower molars that are displaced into the neighbouring spaces

Our aim was to describe our experience of retrieval of accidental displacements of upper and lower molars into neighbouring anatomical spaces. Thirteen patients were evaluated retrospectively in terms of age, sex, affected side, jaw (mandible or maxilla), surgeon's experience, whether the extracted teeth had erupted, which portion of the tooth or teeth was displaced, the anatomical space into which the fragment was displaced, postoperative complaints, timing of the retrieval, type of anaesthesia, and surgical approach. There were no significant differences in sex, affected side, which part of the tooth was displaced, whether the extracted teeth had erupted, type of anaesthesia, or timing of retrieval. We conclude that this condition should be treated, although follow-up alone may be an option. The intraoral lingual pouch approach for complications of mandibular third molars and the intraoral Caldwell-Luc operation for those in the maxilla could be successful options for retrieval.

The effect of education on gender perception and gender role attitudes: An experimental studyToplumsal cinsiyet algısı ve toplumsal cinsiyet rollerine eğitimin etkisi: Deneysel bir çalışma. ACTA ACUST UNITED AC 2017. [DOI: 10.14687/jhs.v14i1.4354]

Sex has been the most important criteria when categorizing and differentiating individuals. While the concept of sex is used to describe the biological side of being a man or woman, the concept of gender refers to the expectations and meanings formed by the society and culture. In this respect, passive roles are thought suitable for women in the social life while men have more active roles. Socialization agents, such as family, media, peer groups and education are playing an active role in transferring the codes related to gender roles. The aim of this research is to test the effectiveness of gender education on the attitudes towards gender perception and gender roles. In accordance with this purpose, an experimental study was designed as a part of the protocol called “Providing Gender Equality, Strengthening Institutional Capacity while Fighting with Violence Against Women, Enhancing Cooperation and Coordination” which was conducted between the Ministry of Turkish National Defense and the Ministry of Family and Social Policies. And an education (Gender Equality and Fighting with Violence Against Women) was given to the research group consisting of 23 participants. In order to collect data, we used Gender Perception Scale and Gender Role Attitude Scale. As a result of the study, firstly the education given to the participants raised their score of gender perceptions and attitudes towards gender roles significantly. It also increased the mean score of men much more than that of women. And after the training, the initial difference between the mean scores of men and women almost disappeared. It was seen that the training increased the final test mean scores of married individuals significantly. After the training, the mean scores of both women and men increased. ÖzetBireyleri, kategorilere ayırmak ve farklılaştırmak için kullanılan ölçütlerden en önemlisi cinsiyet olmuştur. Cinsiyet (sex) kavramı, kadın ya da erkek olmanın biyolojik yönünü ifade etmekte iken, toplumsal cinsiyet (gender) terimi, toplumun ve kültürün yüklediği anlamlara ve beklentilere atıfta bulunmaktadır. Toplumsal hayatta kadınlara pasif, edilgen roller uygun görülürken; erkeklere aktif, etken roller atfedilmektedir. Aile, medya, arkadaş grubu ve eğitim gibi toplumsallaşma ajanları ise toplumsal cinsiyet rollerine ilişkin kodların aktarılmasında etkin bir rol almaktadır. Bu araştırma ile her geçen gün artan toplumsal cinsiyet eşitsizliği ve ayrımcılığını önleme yönünde politikalara öncü olmak için verilen eğitimlerin, toplumsal cinsiyet algısına ve toplumsal cinsiyet rollerine ilişkin tutumlar üzerindeki etkinliğinin sınanması amaçlanmıştır. Bu amaç doğrultusunda Millî Savunma Bakanlığı ile Aile ve Sosyal Politikalar Bakanlığı arasında yapılan “Toplumsal Cinsiyet Eşitliğinin Sağlanması ve Kadına Yönelik Şiddetle Mücadelede Kurumsal Kapasitenin Güçlendirilmesi, İşbirliği ve Eşgüdümün Artırılmasına Dair Protokol” kapsamında verilen “Toplumsal Cinsiyet Eşitliği ve Kadına Yönelik Şiddetle Mücadele Eğitici Eğitimi ”ne katılan 23 katılımcı araştırma grubuna dâhil edilerek deneysel bir çalışma yürütülmüştür. Verilerin toplanmasında Toplumsal Cinsiyet Algısı (TCA) ve Toplumsal Cinsiyet Rolleri Tutum (TCRT) ölçekleri kullanılmıştır. Araştırmanın sonucunda ilk olarak çalışma grubuna verilen eğitimin katılımcıların toplumsal cinsiyet algılarında ve toplumsal cinsiyet rollerine ilişkin tutumların ortalamalarında anlamlı derecede yükseltmiştir. İkinci olarak, çalışma grubuna verilen eğitim, erkeklerin ortalamalarını çok daha fazla arttırmış ve eğitim sonucunda kadın ve erkeklerin ortalamaları birbirine son derece yaklaşmıştır. Bunun yanı sıra verilen eğitim evli bireylerin son test ortalamalarını çok daha fazla arttırdığı görülmüştür. Son olarak verilen eğitim sonrasında hem kadınların hem de erkeklerin ortalamaları yükselmiştir.

Abstract P6-16-01: The importance of loco-regional tumor burden and surgery on survival in patients with de novo stage IV breast cancer; post-hoc analyses of protocol MF07-01

Background: The MF07-01 trial is a multicenter phase III randomized controlled trial of treatment naive stage IV BC patients comparing loco-regional surgery (LRS) followed by appropriate systemic therapy (ST) versus ST alone.

Aims: To evaluate the importance of loco-regional tumor burden and surgery on overall survival rate in patients with de novo stage IV breast cancer.

Methods: At initial diagnosis patients were randomized 1:1 to LRS group or ST group. The surgery was a lumpectomy (L) or mastectomy (M) and sentinel lymph node biopsy (SLNB) ± axillary lymph node dissection (ALND). After surgery all patients received systemic treatment + endocrine treatment (ET) and Trastuzumab based on pathology results. The demographic, pathologic, and clinical characteristics of the patients were recorded.

Results:274 patients were accrued; 138 in the LRS group and 136 in the ST group. The groups were comparable regarding age, BMI, HER2 neu, tumor type and size, histologic grade, and bone and visceral metastasis (all p>0.05). In the LRS group 36 patients (26%) had L+ALND, 92 patients (67%) had M+ALND and 10 patients (7%) had M+SLNB, respectively.

The axillary positivity rate was 89.1%. There were 76 (55%) deaths in the LRS group and 101 (74%) in the ST group during the median 40 (20-51) month follow-up. Overall survival (OS) was 34% higher in the LRS group compared to the ST group (HR: 0.66, 95%CI 0.49-0.88: p = 0.005).

Overall survival rate was higher in LN (+) (p=0.01), tumor size<5cm (p<0.0001), and high histologic grade (HG III, p<0.008) patients who underwent axillary surgery than ST group ; OS rate was with a marginal significant level in patients without axillary involvement (pN0) in the LRS group compared with ST group (p=0.05).

Conclusion: In this subgroup analysis, we observed that patients with high grade tumor, without skin or chest wall involvement and positive axilla who underwent surgery for primary breast tumor and axilla had better overall survival than ST in de novo stage IV breast. These results can be considered in clinical research design for stratification.

SPARCS and Pelli-Robson contrast sensitivity testing in normal controls and patients with cataract

PurposeTo determine the ability of the newly developed internet-based Spaeth/Richman Contrast Sensitivity (SPARCS) test to assess contrast sensitivity centrally and peripherally in cataract subjects and controls, in comparison with the Pelli-Robson (PR) test.MethodsIn this prospective cross-sectional study, cataract subjects and age-matched normal controls were evaluated using the SPARCS and PR tests. Contrast sensitivity testing was performed in each eye twice in a standardized testing environment in randomized order. SPARCS scores were obtained for central, right upper (RUQ), right lower (RLQ), left upper (LUQ), and left lower quadrants (LLQ). PR scores were obtained for central contrast sensitivity. PR and SPARCS scores in cataract subjects were compared with controls. Intraclass correlation coefficients (ICC) and Bland Altman analysis were used to determine test-retest reliability and correlation.ResultsA total of 162 eyes from 84 subjects were analyzed: 43 eyes from 23 cataract subjects, and 119 eyes from 61 controls. The mean scores for SPARCS centrally were 13.4 and 14.5 in the cataract and control groups, respectively (P=0.001). PR mean scores were 1.31 and 1.45 in cataract and control groups, respectively (P<0.001). ICC values for test-retest reliability for cataract subjects were 0.75 for PR and 0.61 for the SPARCS total. There was acceptable agreement between the ability of PR and SPARCS to detect the effect of cataract on central contrast sensitivity.ConclusionsBoth SPARCS and PR demonstrate a significant influence of cataract on contrast sensitivity. SPARCS offers the advantage of determining contrast sensitivity peripherally and centrally, without being influenced by literacy.

Polymicrobial Infection of the Cornea Due to Contact Lens Wear

A 38-year-old male presented with pain and redness in his left eye. He had a history of wearing contact lenses. His ophthalmic examination revealed a large corneal ulcer with surrounding infiltrate. Cultures were isolated from the contact lenses, lens solutions, storage cases, and conjunctivae of both eyes and also corneal scrapings of the left eye. Fortified vancomycin and amikacin drops were started hourly. Culture results of conjunctivae of each eye and left cornea were positive for Pseudomonas aeruginosa; cultures from the contact lenses, lens solution and storage case of both eyes revealed Pseudomonas aeruginosa and Alcaligenes xylosoxidans. Polymerase chain reaction of the corneal scraping was positive for Acanthameoba. The topical antibiotics were changed with ones that both bacteria were sensitive to and anti-amoebic therapy was added. The patient had two recurrences following initial presentation despite intensive therapy. Keratitis occurred due to multiple pathogens; the relapsing course despite adequate therapy is potentially associated with this polymicrobial etiology.

The Impact of Visual Field Clusters on Performance-based Measures and Vision-Related Quality of Life in Patients With Glaucoma

PURPOSE

To investigate how visual field (VF) clusters affect performance-based measures of the ability to perform activities of daily living and subjective measures of vision-related quality of life (QoL) in patients with glaucoma.

DESIGN

Prospective, cross-sectional study.

METHODS

setting: Institutional - Wills Eye Hospital.

STUDY POPULATION

322 eyes of 161 patients with moderate-stage glaucoma.

OBSERVATION

VF tests were conducted using the Humphrey 24-2 Swedish Interactive Thresholding Algorithm standard perimeter. The VFs of each patient were divided into 5 clusters: nasal, temporal, central, paracentral, and peripheral. The score for each cluster was the averaged total deviation scores of all tested points within the cluster. Each cluster score was correlated with performance-based measures of visual function and subjective assessment of vision-related QoL.

MAIN OUTCOME MEASURES

The Compressed Assessment of Ability Related to Vision, the National Eye Institute Visual Functioning Questionnaire 25 (NEI VFQ-25), and the Modified Glaucoma Symptom Scale.

RESULTS

The central VF cluster in the better eye was positively correlated with all Compressed Assessment of Ability Related to Vision (performance-based measure) subscales. The strongest correlation for the better eye was between the central VF cluster and total Compressed Assessment of Ability Related to Vision score (0.39, P < .001). The inferior VF hemisphere in both eyes was positively correlated with most Compressed Assessment of Ability Related to Vision subscales. Central VF clusters in the better eye were positively correlated with a majority of the NEI VFQ-25 subscales. There were no significant correlations between VF clusters and Modified Glaucoma Symptom Scale subscales.

CONCLUSIONS

Scores of central VF defects in the better eye and inferior hemisphere defects in both eyes were positively correlated with performance-based measures of the ability to perform activities of daily living. Glaucoma patients with central defects in the better eye were more likely to have reduced scores on assessments of vision-related QoL.

The SPARCS: a novel assessment of contrast sensitivity and its reliability in patients with corrected refractive error

PURPOSE

To explore the reliability of the Spaeth/Richman Contrast Sensitivity (SPARCS) test and to assess the contrast sensitivity (CS) distribution among subjects with various refractive errors.

METHODS

Cross-sectional study. Ninety-three individuals (182 eyes) with varying amounts of refractive error were included in this study and divided into six groups according to their spherical equivalent. CS was evaluated using Pelli-Robson (PR) and SPARCS assessments. Each eye was tested twice with both measurements. Outcomes included the correlations of PR and SPARCS scores, the test-retest agreement of the two measurements and the limits of agreement between tests of CS measurements. The distribution of CS among the six groups was compared.

RESULTS

Pearson correlation analysis showed statistically significant correlations between SPARCS and PR scores (p<0.001). Reliability analysis showed that SPARCS had better test-retest agreement than PR, with SPARCS exhibiting a higher intraclass coefficient (ICC=0.635). Bland-Altman plots showed that the mean difference of measurements was close to 0 for both CS measurements. Among the six refractive groups, there were no significant differences in CS scores with either measurement.

CONCLUSIONS

SPARCS appears to be a reliable assessment for CS. The difference in CS among myopes, emmetropes and hyperopes wearing their habitual correction was statistically insignificant in this study.

Aspergillus terreus infection in a sutureless self-sealing incision made during cataract surgery

Here, we describe a case of keratitis caused by Aspergillus terreus in an 80-year-old immunocompetent woman 1 month after uneventful cataract surgery. The patient presented with decreased visual acuity (20/50) and severe pain in her right eye. Examination revealed a 3.5 × 4.5 mm white-colored deep stromal infiltration located on the temporal corneal tunnel incision. Corneal scraping samples were obtained for cytological and culture examinations. The cinnamon-brown colonies consisting of a dense felt of conidiophores were identified as A. terreus using molecular data. Using CLSI M38-A2 microdilution method, minimum inhibitory concentration values of amphotericin B, itraconazole, voriconazole, and posaconazole were determined to be 2, 1, 0.25, and 1 μg/ml, respectively, and minimum effective concentration values of caspofungin and anidulafungin were ≤0.03 and ≤0.03, respectively, at 48 h for the A. terreus strain. Antifungal therapy was started as topical 1 % voriconazole drops hourly and 5 % natamycin ointment five times a day; however, corneal infection and melting progressed despite the ongoing intensive treatment and visual acuity dropped to the 20/200 level at the end of the first week. Amniotic membrane transplantation was performed to promote corneal healing. Topical medication was tapered and discontinued within 2 months based on the clinical features. The ulcer healed with scarring and vascularization, and visual acuity improved to 20/50. In conclusion, A. terreus is a very uncommon cause of mycotic keratitis and is especially rare after cataract surgery. We suggest that early and accurate diagnosis and appropriate treatment of A. terreus keratitis may have a major impact on preventing severe disease complications.

Umbilical cord blood serum therapy for the management of persistent corneal epithelial defects

AIM

To evaluate the role of umbilical cord blood serum (CBS) therapy in cases with persistent corneal epithelial defects (PED).

METHODS

Sixteen eyes of 14 patients with PED who were resistant to conventional treatment were treated with 20% umbilical cord serum eye drops. Patients were followed-up weekly until epithelization was complete. The collected data included the grade of corneal lesion (Grade I: epithelial defect+superficial vascularization, Grade II: epithelial defect+stromal edema, Grade III: corneal ulcer+stromal melting), the size of epithelial defect (pretreatment, 7(th), 14(th) and 21(st) days of treatment), and follow-up time was evaluated retrospectively.

RESULTS

The mean size of epithelial defect on two perpendicular axes was 5.2×4.6-mm(2) (range: 2.5-8×2.2-9 mm(2)). Mean duration of treatment was 8.3±5wk. CBS therapy was effective in 12 eyes (75%) and ineffective in 4 eyes (25%). The epithelial defects in 4 ineffective eyes were healed with amniotic membrane transplantation and tarsorrhaphy. The rate of complete healing was 12.5% by 7d, 25% by 14d, and 75% by 21d. The healing time was prolonged in Grade III eyes in comparison to eyes in Grade I or Grade II.

CONCLUSION

The results of the current study indicated the safety effectiveness of CBS drops in the management of PED. The grade of disease seems have a role on the healing time.

Is retinopathy of prematurity decreasing?--comparison of two different periods in the same NICU

Retinopathy of prematurity is a retinal vascular disorder seen frequently in very premature infants, and is associated with poor clinical outcomes. The aim of the present study was to assess the association between the incidence of retinopathy of prematurity and mechanical ventilation, oxygen therapy, gestational age, and antenatal steroids in extremely low birth weight infants as well as to retrospectively analyze changes in the incidence and risk factors of retinopathy of prematurity over two study periods.

Human placental macrophages (Hofbauer cells) in severe preeclampsia complicated by HELLP syndrome: immunohistochemistry of chorionic villi

OBJECTIVE

To evaluate Hofbauer cells in the placentas of women diagnosed with HELLP syndrome.

STUDY DESIGN

The present study compared 20 patients with HELLP syndrome and 20 control patients with respect to demographics, hematological parameters and the presence of Hofbauer cells in placental samples. CD-68 antibody was used for immunohistochemical examination. The total number and size of Hofbauer cells were measured in the placental villi, and the proportion of Hofbauer cells relative to the vascular structure was also compared between groups.

RESULT

The patient and control groups were similar according to baseline obstetric characteristics. White blood cell counts in patients with HELLP syndrome and the control group were 15,139 +/- 4,169 and 10,806 +/- 2,888, respectively, and were significantly increased among patients with HELLP syndrome (p < 0.001). Hofbauer cell numbers in the placental villi of patients with HELLP syndrome were significantly elevated in comparison to normotensive controls (p = 0.046). The proportion of Hofbauer cells in the placental villi according to proximity to the vascular structure were 3.85 +/- 1.66 in the HELLP group and 1.75 +/- 1.12 in controls (p < 0.001). Sizes of the Hofbauer cells were not statistically different between groups.

CONCLUSION

Increased Hofbauer cells may be associated with increased inflammation or may have an adaptive mechanism at the fetal site of the placenta in patients with HELLP syndrome.

Surgical rehabilitation following ocular chemical injury

PURPOSE

The purpose of this study is to evaluate the management of limbal stem cell deficiency (LSCD) secondary to chemical ocular burns.

MATERIALS AND METHODS

The charts of 48 eyes of 40 patients with grade 2 or higher chemical injury were evaluated retrospectively. Subjects with follow-up longer than 1 year were included. Medical treatment, surgical correction of abnormalities of ocular adnexial structures, limbal stem cell transplantation from patient's fellow eye, from living relatives or from cadaveric donor, amniotic membrane transplantation, conjunctival epitheliectomy, chelation with ethylenediaminetetraacetic acid and penetrating keratoplasty were the treatment modalities. Outcome measures were ocular surface stability and corrected distance visual acuity (CDVA). Failure was defined as the appearance of persistent epithelial defect (nonhealing epithelial defect for more than 2 weeks) with progressive corneal conjunctivalization/vascularization and thinning, and also progression of conjunctivalization to the central 6 mm of the cornea in eyes with subsequent keratoplasty.

RESULTS

The mean age of 31 male and 9 female patients were 32.32 ± 12.6 years. LSCD was bilateral in 8 cases. The mean follow-up was 77.2 ± 35.1 months. The presentations were in acute phase in 37.5%, in subacute phase in 32.5% and in chronic phase in 30% of the patients. Only 13 of 48 (27.1%) eyes obtained sufficient ocular surface stability through medical treatment; however, only 5 of these eyes achieved CDVA of less than 0.7 logMAR. Limbal stem cell transplantation was performed in 26 eyes as conjunctival limbal autograft, living-related conjunctival limbal allograft and keratolimbal allograft or as a combination of these transplantations. At the last visit, 30 eyes (62.5%) had an intact and stable ocular surface. Clear cornea was achieved in 11 (78.6%) of 14 eyes with grade 2 injury, in 9 (60%) of 15 eyes with grade 3 injury, in 5 (50%) of 10 eyes with grade 4 injury, in 1 (16.6%) of 6 eyes with grade 5 injury and in 1 (33.3%) of 3 eyes with grade 6 injury. The CDVA that was 1.66 ± 0.99 logMAR initially improved to 0.87 ± 0.85 logMAR at the last visit (p < 0.001).

CONCLUSION

While patients with low-grade chemical injury seem to benefit quite well from the medical treatment, amniotic membrane transplantation, limbal graft transplantation and subsequent keratoplasty; patients with severe injuries seem to be more prone to failure after all of the available treatment modalities.

Topical anesthetic eye drops abuse: are we aware of the danger?

OBJECTIVE

To investigate the clinical results of topical anesthetic drug (TAD) abuse and to evaluate the results in terms of preventive medicine and public health.

METHODS

Patients who had been followed in a cornea unit between March 2009 and November 2011 for TAD abuse keratopathy were included in the study. The demographics, duration of TAD use, symptoms, ocular findings, treatment modalities, visual acuities, complications and accompanying psychiatric problems data were obtained from medical records.

RESULTS

Twelve eyes of 8 patients (3 females and 5 males) were evaluated retrospectively. One of the patients was provided the drug with a primary care pratitioner's prescription and for the other 7 patients, it was available from pharmacies without prescription. According to their clinical history, 4 patients were suffering from exposure to welding flash with a corneal foreign body, 2 from lagophthalmus-related keratopathy, 1 from traumatic corneal abrasion, and 1 from exposure to silica dust at work. The mean duration of TAD usage was 14.8 ± 7.78 days. Slit-lamp examination revealed corneal epithelial defect in all eyes, stromal opacity in 11 eyes and ring-shaped infiltrates in 8 eyes.

CONCLUSION

Uncontrolled overuse of TAD can lead to serious ocular morbidities. Similarity of the clinical signs of this abuse to those of infectious keratitis together with the fact practitioners and managers to take measures to prevent the ready supply of these drugs from pharmacies and to raise public awareness with education programs.
