Human otoacariasis:Demographic and clinical outcomes in patients with ear-canal ticks and a review of literature

Introduction:Otoacariasis is a rare infestation of the ear canal,which affects the quality of life especially in rural areas.Different types of ticks and mites may cause otoacariasis.Although treatment of otoacariasis is simple,diseases transmitted through ticks and mites should be considered during diagnosis and treatment.Both local and systemic signs and symptoms of such diseases should be followed up.A literature review was conducted in PubMed using the following terms: 'otoacariasis,' 'ticks,' 'mites,' and 'outer ear canal infestations.' Demographic,radiologic,and treatment options were discussed.Treatment hints and pitfalls were also discussed with the literature review.Conclusion:In this paper,we describe otoacariasis in humans and discuss the appropriate interventions.

Is the Use of Frozen Section Indispensable in the Surgical Treatment of Endometrial Hyperplasia?

Objective: To evaluate the reliability and accuracy of frozen section (FS) compared with final pathology and to determine whether they should be obligatory in every patient with atypical endometrial hyperplasia (AEH). Methods: We retrospectively assessed the medical records of 192 patients whose endometrial biopsy results were endometrial hyperplasia and underwent hysterectomy at our center. Results: Twenty-two (11.4%) of the 192 patients in our study had concurrent endometrial carcinoma (EC). Of these, 21 (95.5%) were EC and 1 (4.5%) was non-endome- trioid. Of the 140 patients with AEH, 20 (14.3%) had concurrent EC. Overall, 157 patients had FS. Two (1%) patients’ EC was higher than grade 1B and needed lymphadenectomy. The positive and negative predictive value, specifity and sensitivity of FS were found to be 77.8%, 95.7%, 97% and 70%, respectively. Conclusion: Patients who have AEH without high-risk comorbidities do not have to be referred to oncology centers and can undergo hysterectomy in community hospitals without FS.

Protective effect of pomegranate juice on retinal oxidative stress in streptozotocin-induced diabetic rats

AIM： To investigate the effect of pomegranate juice（PJ） intake on overall oxidation status in retinas of diabetic rats.METHODS： Twenty-seven rats were divided into four groups as control（CO）, diabetic（DM）, control treated with PJ（CO-PJ）, and diabetic treated with PJ（DM-PJ）.The retina tissues were used to determine 8-hydroxy-2＇-deoxyguanosine（8 OHd G）, malondialdehyde（MDA）, reduced glutathione（GSH） levels, and the enzyme activities of superoxide dismutase（SOD） and glutathione peroxidase（GSH-Px）. RESULTS： The levels of 8 OHdG and MDA were significantly increased in the retina of DM group compared to CO group（P=0.001, P〈0.001 respectively）. Both 8 OHd G and MDA levels were decreased in PJ-DM group compared to DM group（P=0.004, P〈0.001 respectively）. The activities of antioxidant enzymes GSH, SOD, and GDH-Px were significantly decreased in the retina of DM group compared to CO group（P≤0.01）. GSH and GSH-Px activities were higher in PJ-DM group compared with DM group（P=0.010, P=0.042, respectively） but SOD activity was not statistically different（P=0.938）. CONCLUSION： PJ intake is found to be effective in decreasing oxidative end products, and in increasing the activities of antioxidant enzymes in diabetic retinas of rats, which suggests it may be effective against oxidative stress in diabetic retinas.

Posterior Dislocation of the Hip in a 4-Year-Old Boy

Traumatic hip dislocations occur in children below 15 years old. Just as in adults, posterior hip dislocations are 10 times more common than anterior hip dislocations. Traumatic hip dislocation in pediatric

Effect of early atopic sensitization in children aged 0–2 years on the development of asthma symptoms at 9–11 years of age

Background Personal genetic predisposition and early life environmental factors are important for the development of childhood asthma.We aimed to search whether egg,milk and mite sensitizations at 0–2 years old are risk factors for asthma symptoms at 9–11 years old.Methods A total of 210 wheezer children who had specific immunoglobulin(Ig)E in 2010–2012 were included in the study(followed by pediatric allergy).Patients were divided into non-atopic(group 1,n=157)and atopic patients[groups 2–7,n=53(5 patients were in both group 4 and group 5)]based on sensitizations.Using the International Study of Asthma and Allergy in Childhood questionnaire,current wheeze(CW,2nd question),exercise wheezing(EW,7th question),and dry cough(DC,8th question)were surveyed.Also,parental allergies,eczema at 0–2 years,current eosinophil percentage and total IgE were recorded.Results Eczema was observed as an important risk factor[CW:odds ratio(OR)=2.83,95%confidence interval(CI)=1.54–5.23,P≤0.001;EW:OR=2.71,95%CI=1.33–5.54,P=0.006;DC:OR=3.03,95%CI=1.47–6.25,P=0.003],whereas having no atopic sensitization at 0–2-year-old(group 1)was found as a significant protective factor for asthma at 9–11 years old(CW:OR=0.32,95%CI=0.15–0.70,P=0.004;EW:OR=0.21,95%CI 0.10–0.44,P≤0.001;DC:OR=0.25,95%CI=0.10–0.59,P=0.002).Conclusion Early personal eczema is a significant risk factor for the development of asthma symptoms at 9–11 years old,whereas not having an allergic sensitization at 0–2 years old(group 1)is an important protective factor.
