ABSTRACT
PURPOSE: The aim of this study is to evaluate the prevalence of anxiety disorders, its correlation with sociodemographic characteristics, its comorbidities with other psychiatric disorders and its predictors in school-aged children. METHODS: This study is part of a representative, multi-centered national study that is planned by the Turkish Association of Child and Adolescent Mental Health to evaluate the prevalence of psychopathology among elementary school students in Turkey between the years 2014-2015. Children are screened via Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version. Impairment is assessed by a 3-point Likert type scale independently by the parent and the teacher. The final sample included 5842 children with the mean age of 8.7 years. RESULTS: The prevalence of any anxiety disorder without considering impairment is 16.7% and considering impairment is 5.2% in children according to our study. We found significant differences for comorbid Attention Deficit Hyperactivity Disorder, Disruptive Behavior Disorder, Mood Disorders, Tic Disorders, Obsessive Compulsive Disorder, Enuresis Nocturna, Encopresis, and Intellectual Disability. Having a history of paternal physical disorder, living in the regions of Marmara, Mediterranean and Black Sea were found to be the main predictors of having childhood anxiety disorders according to the logistic regression analysis. CONCLUSION: Better understanding of childhood anxiety disorders, comorbid conditions and predictors will result in earlier diagnosis and more appropriate treatment.

OBJECTIVE: Some studies suggest that serum sodium level may decrease at a greater degree in complicated acute appendicitis (CA) because of the increased severity of inflammation. This study aimed to determine the predictive value of some inflammatory markers and hyponatremia in differentiating CA from uncomplicated acute appendicitis (UCA). PATIENTS AND METHODS: In this retrospective cohort study, the data of patients who underwent urgent appendectomy in Department of General Surgery, Eskisehir Osmangazi University from January 01, 2016 to January 01, 2021, were analyzed. Patients were divided according to appendicitis type, UCA and CA. RESULTS: In this study, 10.2% (n = 79) of 772 acute appendicitis cases were CA. Multiple logistic regression analysis revealed that high age (p = 0.001), male sex (p = 0.014), high leukocyte count (p = 0.045), low lymphocyte count (p = 0.023) and hyponatremia (p <0.001) were independently associated with CA. Patients with hyponatremia (sodium level ≤134 mEq/L) had 3.050-fold higher risk for CA than patients with normal sodium level (odds ratio: 3.050, 95% confidence interval: 1.668-5.576). The results of the ROC analysis performed to assess the role of sodium level in detecting CA showed a sensitivity of 27.8% and a specificity of 92.1% (cut-off: 133.5 meq/L) (p = 0.001; area under the curve: 0.612 [0.539-0.684]). CONCLUSIONS: Clinicians should be aware of the higher likelihood of CA occurrence in patients with appendicitis in whom hyponatremia, leukocytosis, or lymphopenia is detected in the laboratory examination.

OBJECTIVE: This study aimed to investigate the effect of surgical incision on the auricle position in patients undergoing canal wall down mastoidectomy to treat chronic otitis media. METHODS: Thirty-four patients who had undergone canal wall down mastoidectomy with a post-auricular incision approach were included in the study. Patients who had a previous auricle deformity, who underwent limited mastoidectomy surgery or mastoid obliteration, or who were younger than 18 years of age were excluded. The distances of the upper and middle parts of the auricle to the mastoid were measured. RESULTS: Measurements in the first post-operative year were found to be 13.15 ± 3.59 mm in the upper region and 16.29 ± 5.00 mm in the middle region. It was observed that the auricle was approaching the mastoid area in both regions. CONCLUSION: In patients undergoing radical mastoidectomy, the distance between the auricle and the mastoid may decrease, leading to narrowing of the auriculo-cephalic angle.

OBJECTIVE: Too much screen time is a common and severe threat to child health and excessive screen exposure exists in the early childhood population in Turkey. We aimed to investigate the associations between excessive screen time and psychosocial well-being in a sample of Turkish preschool children. METHODS: Mothers and their healthy children aged 2-5 years who applied to general pediatric outpatient clinics for well-child examinations were enrolled in this descriptive cross-sectional study. Children with a daily screen time of less than 1 h (low) or more than or equal to 4 h (excessive) were included. Psychosocial well-being was assessed using the parent version of the Strengths and Difficulties Questionnaire. RESULTS: In all, 220 mother-child pairs participated in this study. Emotional symptoms, conduct problems, peer relationship problems, and total difficulties scores were significantly higher in the children with excessive screen time (p<0.05), while the hyperactivity-inattention and prosocial scores were not different between the low and excessive screen time groups (p>0.05). After adjusting for potential confounders, the children with excessive screen time had significantly increased odds ratios for having conduct and peer relationship problems (OR [95% CI]: 2.62 [1.11-6.19], p = 0.028 and 2.57 [1.25-5.26], p = 0.010, respectively). CONCLUSION: Turkish preschool children with excessive screen time were significantly more likely to have poor psychosocial well-being. Preschool children with behavioral problems should be evaluated for excessive screen time.

Proprotein convertase 1/3 (PC 1/3) deficiency is a rare, autosomal recessive disorder caused by mutations in the PCSK1 gene. The disease is characterized by early-onset chronic diarrhea/malabsorption, followed by severe obesity and hormonal deficiencies such as hypocortisolism, hypothyroidism, diabetes insipidus, hypogonadism, growth deficiency, and diabetes mellitus. Ewing's sarcoma is a rare tumor, usually of small dimensions of neuroectodermal origin that is difficult to distinguish pathologically from a primitive neuroectodermal tumor. A 22-year-old female patient with PC 1/3 deficiency was admitted to our clinic with recurrent urinary tract infections. Magnetic resonance imaging (MRI) revealed an 11x12 cm pelvic mass displacing the uterus. A core-needle biopsy was performed on the pelvic mass. As a result of the pathological evaluation, it was diagnosed with pelvic Ewing's sarcoma. The patient was started on the VAC-IE chemotherapy protocol. We report a case of pelvic Ewing's sarcoma in a patient with PC 1/3 deficiency. Further research is needed to assess malignancy risk in metabolic disorders including very rare disorders like PC 1/3 deficiency.
ABSTRACT
OBJECTIVE: This study evaluated the functional results of the superior pedicled composite multi-fractured osteoperiosteal flap technique. This method is a novel technique for the reconstruction of the external auditory canal. The study also examined the effect of the superior pedicled composite multi-fractured osteoperiosteal flap technique on patients' disease-related quality of life. METHOD: A total of 37 patients who underwent the superior pedicled composite multi-fractured osteoperiosteal flap technique were enrolled in the study. Their functional hearing results and disease-related quality of life scores were evaluated. RESULTS: A significant improvement was observed in the patients' hearing scores at the post-operative sixth month relative to the pre-operative period, and the patients' disease-related quality of life increased significantly. CONCLUSION: The superior pedicled composite multi-fractured osteoperiosteal flap method can be safely used, especially in patients undergoing retrograde mastoidectomy because of limited cholesteatoma. This method contributes to improving patients' hearing levels and disease-related quality of life.
ABSTRACT
BACKGROUND: Cholesteatoma-related bone destruction is the cause of many complications due to chronic otitis media. This study aimed to evaluate osteoclastic activity in cholesteatoma-related bone destruction using tartrate-resistant acid phosphatase 5b, an enzyme specific to osteoclastic activity. METHOD: Seventy-two patients diagnosed with chronic otitis media were included in this study and were divided into two groups: with and without bone destruction. The blood serum and tissue tartrate-resistant acid phosphatase 5b levels from both groups were compared. RESULTS: There were no significant differences in the level of serum enzymes between both groups. However, in tissue samples, tartrate-resistant acid phosphatase 5b levels were significantly lower in the bone destruction group than the group without bone destruction. CONCLUSION: This study determined that the level of tartrate-resistant acid phosphatase 5b, a specific enzyme for osteoclastic activity in cholesteatoma-related bone destruction, is locally decreased. This data suggests that osteoclastic activity may decrease in cholesteatoma-related bone destruction. However, further experimental and clinical studies are required to clarify this highly complex mechanism.

The superficial location of critical structures, including tendons, nerves and vessels, in the volar surface of the wrist makes them vulnerable to penetrating trauma. Extensive injuries to these structures are described as "spaghetti wrist". The main objective of this study was to report functional outcome in spaghetti-wrist injuries. The records of patients presenting to our clinic with extensive volar wrist injuries between January 2016 and January 2019 were reviewed retrospectively. Age, gender, comorbidities, date of injury, injury mechanism, affected hand and transected structures were noted. Tendon function, opposition, intrinsic hand function, deformity and sensitivity were evaluated following the Noaman report. The Michigan Hand Outcomes Questionnaire (MHOQ) was used to evaluate hand-specific outcomes. Twenty patients were included. Mean age was 32.7 years (range, 18-47 years). Mean follow-up was 21.9 months (range, 12-50 months). Mean number of injured structures was 11.9 (range, 10-16 structures) per patient. Physiotherapy duration had an effect on postoperative outcome in all six MHOQ domains (r = 0.821, p = 0.00001). However, no significant difference in overall hand function was found according to the number of injured structures (r = -0.105, p = 0.661). Precise initial evaluation, meticulous surgical treatment within 24 h and early physical therapy are essential after spaghetti-wrist injury. Good functional results are associated with prolonged physical therapy, but not with the number of structures injured.

BACKGROUND: The Southern Karaman sheep, which is very fertile in terms of meat and milk production and is often preferred in livestock raising, is known as a domestic sheep breed. The Hasak sheep is a breed formed by the triple crossbreeding of the German Black-headed, Hampshire and Akkaraman breeds. Arterial feeding of the forelimb is provided by arteria axillaris, a continuation of arteria subclavia. In this study, it was aimed to examine the forelimb arteries in Southern Karaman and Hasak sheep breeds. MATERIALS AND METHODS: Totally, 8 Southern Karaman and 8 Hasak sheep were obtained from Konya Bahri Dagdas International Agricultural Institute. The sheep were anesthetised with xylazine and ketamine and extravasated by cutting the arteria carotis communis in the neck area of the sheep. The forelimbs of the sheep separated from the body were fixed in 10% formaldehyde solution and then dissections were made and the course and branching of the arteries were examined. RESULTS: It was determined that the arteria brachialis was divided into two main branches as distal arteria brachialis and proximal arteria subscapularis at the articulatio humeri level of the arteria axillary. Arteria mediana, which is a continuation of arteria brachialis, was also examined in different parts of antebrachium and ended by splitting into branches. CONCLUSIONS: According to the findings of the Southern Karaman and Hasak sheep breeds, it was determined that the forelimb arteries had some anatomical differences but were similar in structure to many sheep breeds.

BACKGROUND: The interdigital glands of sheep perform various functions including those pertaining to sexual behaviours. Morphological and histological structure of the gland demonstrates differences among species. The aim of this study is to examine the morphological and histological structure of Hasak and Hasmer sheep's interdigital glands and to determine the differences with other sheep breeds. MATERIALS AND METHODS: For this research, we selected 7 Hasak and 7 Hasmer female sheep. After scarification, the feet were obtained and used for anatomical and histological examinations. For the histological examination, the interdigital gland tissues were stained with Crossman modified triple, periodic acid Schiff (PAS) and Alcian blue (AB) staining. RESULTS: The morphometric analysis results, mean values of weight, body length, body diameter, flexura, ductus length, ductus diameter, were observed as 0.80 mm, 14.61 mm, 5.98 mm, 5.62 mm, 26.58 mm, and 3.25 mm, respectively in Hasak and 0.8 mm, 15.46 mm, 6.37 mm, 5.70 mm, 24.52 mm, and 3.52 mm in Hasmer sheep. The histochemical staining revealed that the apocrine secretion of this gland was PAS positive and AB negative. CONCLUSIONS: The weight, body length, body diameter, flexura, ductus length and ductus diameter in the forefoot's interdigital glands of both Hasak and Hasmer sheep were higher in a statistically significant manner than those of the hindfeet's glands.

The "crumple zone" hypothesis suggests that the paranasal sinuses protect the brain as a zone to distribute and absorb energy after trauma to the head. We investigated the relation between the size of the frontal sinus and mortality in patients with cranial trauma. All patients with head trauma admitted to the ICU between 1 January 2016 and 20 December 2017 were reviewed retrospectively. They were divided into two groups (according to their outcome) : died and survived. The volumes of the frontal sinuses and other trauma-related variables were assessed on computed tomographs (CT) on admission. Admission CT of 33 patients (24 male, and nine female, aged between 18-92 years, mean 43) were obtained. Male patients had significantly larger frontal sinuses than female (10.24 compared with 6.6cm3). Larger sinuses were significantly associated with a worse outcome (p=0.005). The size of the frontal sinus correlates with mortality after cranial trauma. Our findings do not confirm the "crumple zone" hypothesis, and suggest that the larger the sinus, the greater the risk of death. To our knowledge this is a new finding that warrants further validation.

The aim of this study was to compare the intra and inter genetic variability and population structure of 7 indigenous chicken breeds of the Veneto region, through a novel panel of 64 SNP, each located in an exonic region and mostly on different chromosomes. A total of 753 blood samples from 7 local chicken breeds (Ermellinata di Rovigo, Millefiori di Lonigo, Polverara, Pepòi, Robusta Lionata, Robusta Maculata, and Padovana) was collected and analyzed. Two strains of Polverara (Nera and Bianca) and Padovana (Dorata and Camosciata) were included in the study. The observed heterozygosity ranged from 0.124 (Pèpoi) to 0.244 (Ermellinata di Rovigo), and the expected heterozygosity varied from 0.132 (Millefiori di Lonigo) to 0.300 (Ermellinata di Rovigo). Global FIS results (0.114) indicated a low-medium inbreeding effect, with values ranging from 0.008 (Millefiori di Lonigo) to 0.223 (Ermellinata di Rovigo). Pairwise FST values (0.167) for all populations ranged from 0.020 (Polverara Nera and Polverara Bianca) to 0.193 (Robusta Lionata and Polverara Nera), indicating that the studied breeds were genetically highly differentiated. The software STRUCTURE was used to detect the presence of population substructures, and the most probable number of clusters (K) of the 10 chicken populations was at K = 8. The affiliation was successful in all Veneto chicken breeds. The present SNP marker results, compared with previous data obtained using microsatellites, provided a reliable estimate of genetic diversity within and between the studied breeds, and demonstrated the utility of the proposed panel as a rapid, efficient, and cost-effective tool for periodical monitoring of the genetic variability among poultry populations. In addition, the present SNP panel could represent a resource for a systematic approach with relevant impact on breeding program decisions and could turn out to be a reliable tool for genetic traceability of indigenous chicken meat. Adoption of a periodical monitoring system of genetic diversity is a fundamental tool in conservation actions and should increase the value of typical and niche products.

OBJECTIVE: The Bethesda classification was introduced in 2008 to provide standardisation in the evaluation of thyroid fine needle aspiration cytology (FNAC). We compared the diagnostic value of pre-Bethesda and Bethesda classification systems in the differentiation of benign and malignant thyroid nodules. METHODS: Medical records of patients who underwent a thyroidectomy between June 2007 and June 2014 were reviewed retrospectively. Nodules evaluated with FNAC before March 2010 were classified as pre-Bethesda (non-diagnostic, benign, indeterminate, suspicious for malignancy and malignant), and those evaluated after March 2010 were considered Bethesda (non-diagnostic, benign, atypia of undetermined significance/follicular lesion of undetermined significance, follicular neoplasia/suspicious for follicular neoplasia, suspicious for malignancy and malignant). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of the two classification systems were calculated. RESULTS: There were 1810 nodules in the pre-Bethesda and 5115 nodules in the Bethesda group. The non-diagnostic rate was significantly higher, and benign and suspicious for malignancy rates were lower in Bethesda compared with the pre-Bethesda group (P<.001 for each). When benign cytology was considered negative, and indeterminate, follicular neoplasia/suspicious for follicular neoplasia, suspicious for malignancy and malignant cytologies were considered positive, results for pre-Bethesda and Bethesda were as follows: sensitivity, 78.9% and 78.5%; specificity, 86.6% and 97.0%; PPV, 42.8% and 72.6%; NPV, 97% and 97.8%; and accuracy, 85.7% and 95.3%, respectively. CONCLUSIONS: Among operated nodules, percentages of benign and suspicious for malignancy cytologies decreased, and percentages of non-diagnostic and uncertain cytologies increased with the implementation of Bethesda. The diagnostic value of FNAC seems to have increased with the use of Bethesda classification.

PURPOSE: The incidence of thyroid cancer is increased in elderly patients. It tends to be larger and have more aggressive characteristics in these patients. Our aim was to compare features of thyroid carcinoma in geriatric and non-geriatric patients. METHODS: In total, 933 patients with thyroid cancer were retrospectively reviewed. Thyroid functions, ultrasonography features of malignant nodules, cytological and histopathological findings and the rates of recurrence and persistence were compared in patients ≥65 and <65 years old. RESULTS: There were 153 malignant foci in 109 (11.7%) patients ≥65 and 1185 malignant foci in 824 (88.3%) patients <65 years old. Mean nodule diameter was significantly higher in geriatric patients (p = 0.008). Most of the ultrasonographical features of malignant nodules were similar in two groups. Hypoechoic halo was observed in 16.4 and 28.6% of malignant nodules in geriatric and non-geriatric group, respectively (p = 0.034). There was no significant difference in cytological diagnosis. Histopathologically, tumor diameter, rates of microcarcinomas and incidentality were similar. Of all cancer types, 88.8% in geriatric and 93.9% in non-geriatric group were papillary thyroid cancer (p = 0.028). Hurthle cell cancer constituted 3.9 and 1.1% of carcinomas in geriatric and non-geriatric patients, respectively (p = 0.015); 2.0 and 0.2% of tumors in geriatric and non-geriatric group were anaplastic, respectively (p = 0.012). Capsular and vascular invasion, extrathyroidal extension, persistence and recurrence rates were similar. CONCLUSIONS: Rates of anaplastic cancer and Hurthle cell cancer which is known to have worser prognosis among other differentiated thyroid cancers are increased in geriatric ages. Cytological evaluation of thyroid nodules should strongly be considered due to increased tendency for aggressive tumor types in these patients.

BACKGROUND: A fine needle aspiration biopsy (FNAB) is the most valuable diagnostic procedure for pre-operative discrimination of benign and malignant nodules. The Bethesda System for Reporting Thyroid Cytopathology provides standardised reporting and cytomorphological criteria in aspiration smears. The aim of the present study was to determine malignancy rates in nodules with different cytology results and evaluate the diagnostic value of Bethesda for variants of papillary thyroid carcinoma (PTC). MATERIALS AND METHODS: A retrospective analysis of 2534 cases with 5784 thyroid nodules, who underwent FNAB followed by surgery, were included in this study. FNAB was performed with ultrasonography guidance. Cytological diagnoses were classified as: non-diagnostic (ND), benign, atypia of undetermined significance/follicular lesions of undetermined significance (AUS/FLUS), follicular neoplasm/suspicious for follicular neoplasm (FN/SFN), suspicious for malignancy (SUS) and malignant. Histopathological diagnoses were classified into four groups: benign, PTC, follicular thyroid cancer and other types of thyroid cancer (including medullary thyroid cancer, undifferentiated thyroid cancer and thyroid tumours of uncertain malignant potential). Cases with PTC were further divided into four categories: conventional variant, follicular variant, aggressive variants (tall cell, diffuse sclerosing and columnar variant) and other variants (oncocytic, solid/trabecular and warthin-like variants). FNAB results were compared with histopathological results. RESULTS: Malignancy rates were 6.3%, 3.2%, 20.7%, 33.3%, 74.2% and 95.6% in the nodules with ND, benign, AUS/FLUS, FN/SFN, SUS and malignant cytology results, respectively. Pre-operative cytology was malignant or SUS in 56.6% of conventional, 24.3% of follicular, 92% of aggressive and 41.7% of other variants of histopathologically confirmed PTC. The difference between the groups was significant (P < 0.001). CONCLUSION: The Bethesda classification is a reliable indicator of malignancy in nodules with different cytology results and seems to be very effective in predicting the malignancy for the nodules diagnosed with aggressive variant PTC on the final histological examination.

Mass gatherings pooling people from different parts of the world-the largest of which is to Mecca, Saudi Arabia, for Hajj-may impose risks for acquisition and dissemination of infectious diseases. A substantial number of pilgrims to Hajj and Umrah are Turkish citizens (456,000 in 2014) but data are lacking on scale of the problem. We did a retrospective cross-sectional multicenter study in Turkey to explore the range of infections among inpatients who had recently returned from the Arabian Peninsula. Our inclusion criteria were patients who had acquired an infection during their trip to an Arabian Peninsula country, or who became symptomatic within 1 week of their return. The data were collected retrospectively for January 1, 2013 and March 1, 2015. 185 Turkish patients were recruited to the study across 15 referral centers with travel associated infectious diseases after returning from Arabian Peninsula countries (predominantly Saudi Arabia 163 [88.1 %] for religious purposes 162 [87.5 %]). Seventy four (40.0 %) of them were ≥ 65 years old with numerous comorbidities including diabetes (24.3 %) and COPD (14.1 %). The most common clinical diagnosis was respiratory tract infections (169 [91.5 %]), followed by diarrheal diseases (13 [7 %]), and there was one case of MERS-CoV. Patients spent a median of 5 (3-7) days as hospital inpatients and overall mortality was 1.1 %. Returning travellers from the Arabian Peninsula present as inpatients with a broad range of infectious diseases similar to common community acquired infections frequently seen in daily medical practices in Turkey.

Ovarian cancer is the most common cause of gynecologic cancer death. Both morphologically and immunohistochemically, metastatic mucinous tumors are the best mimickers of mucinous ovarian tumors; its pathogenesis still remains a mystery. PAX2 and PAX8 immunohisyochemistries are useful for differentiating numerous primary tumour types from metastatic ones. There are few studies in literature about PAX expressions in mucinous and seromucinous tumors. None of these are takes into account the histologic type (whether it is seromucinous or mucinous) or the metastatic origin. With this purpose hematoxylin and eosine slides of ovarian mucinous and seromucinous tumors were re-evaluated and one block was chosen for each case. The study included 76 ovarian mucinous and seromucinous tumors of the ovary reported in Hacettepe University department of pathology between 2000 and 2013. Tissue microarray (TMA) was designed from the chosen blocks, PAX2, PAX8, CDX2 immunostains was preformed to the TMA slides. As a result, most of the metastatic cases were negative for PAX2 (91.2 %) and PAX8 (86.3 %), many were diffusely and strongly positive for CDX2 (68.2 %). Seromucinous tumors were devoid of CDX2 expression; but all cases (except one) displayed strong and diffuse positivity with PAX8. In other words differing from mucinous tumors, seromucinous tumors show strong PAX8 positivity-similar to serous tumors. This study shows that PAX8 and CDX2 could be useful in differentiating primary mucinous from metastatic tumor. Furthermore unlike the homogeneity in seromucinous tumors for PAX8 and CDX2 mucinous tumors shows heterogeneity with different expression patterns.

Postpartum osteoporosis (PPO) is a rare disease associated with pregnancy and lactation period. Here, we report severe PPO and multiple vertebral compression fractures in two patients treated with enoxaparin--low-molecular-weight heparin (LMWH)--throughout their pregnancy. A 34-year-old woman who has delivered her second baby 3 months ago presented with severe low-back pain. She was treated with enoxaparin 40 mg/day for 8 months during her pregnancy. Dual-energy X-ray absorptiometry (DEXA) showed low T- and Z-scores in lumbar (L) vertebras. In magnetic resonance imaging (MRI), severe height losses in thoracic (T) 12, L1, and L2 vertebras were detected. She was diagnosed to have severe PPO and multiple vertebral compression fractures and was prescribed risedronate 35 mg/week, calcium, and vitamin D. The other patient was a 36-year-old woman diagnosed with PPO and vertebral fractures at the third week postpartum. She was also treated with enoxaparin 60 mg/day during her pregnancy. Severe osteoporosis in L vertebras and height losses indicative for compression fractures in T5-8, T11-12, and L2-5 vertebras were detected by DEXA and MRI, respectively. She was treated with calcitonin 200 U/day, calcium, and vitamin D. These findings suggest that vertebral compression fractures and PPO may be one of the causes of severe back pain in postpartum patients. Treatment with LMWH during pregnancy might be considered as a new risk factor for this rare condition.
