Hepatitis E virus seroepidemiology and its change during 1 year in primary school students in Ankara, Turkey.

The Hepatitis E virus (HEV) is widespread throughout the world. The purpose of this study was to evaluate the time-related change of antibody levels against Hepatitis E in primary school children. In this cross sectional study, the samples of 515 students were examined at two times. The mean age of the students was 7(6-13) years. The seroprevalences of anti-HEV were 1.7% and 2.1% at the first and second visits respectively. There was no statistically significant differences between anti-HEV seropositivity and the parents' education and employment status (p >0.05). This serosurvey shows that there is not a high prevalence of enterically transmitted viral hepatitis in Ankara, Turkey, which is a situation similar to developed countries.

Evaluation of Achilles tendon thickening in type 2 diabetes mellitus.

AIM: To investigate the effect of diabetes mellitus on the Achilles tendon, which may contribute to the long-term complications in the foot-ankle complex and to investigate the factors relating to its thickening. METHODS: The study group included 55 patients (26 female and 29 male) with type 2 DM, while the control group included 34 non-diabetic people (13 female and 21 male). We matched the female and male DM patients with their respective control groups in terms of age, BMI, height and body weight. Clinical and biochemical tests, as well as ultrasonographic evaluations of the internal carotid artery and the Achilles tendon, were carried out to evaluate the complications of diabetes mellitus, and to compare the Achilles tendon thickness (ATT) between the study and the control groups. RESULTS: In the female groups the Achilles tendon was significantly thicker in the diabetic patients than in their healthy controls (p<0.001). However, no difference was found in the ATT between the male diabetic patients and their male controls (p=0.74). The ATT correlated with the body mass index (BMI) (r=0.47, p=0.015) and body weight in diabetic female group (r=0.56, p=0.003). We also observed that the ATT values were higher in male DM patients with retinopathy (p=0.034) or neuropathy (p=0.019) compared to the male DM patients without these complications. CONCLUSIONS: The ATT in type 2 female diabetic patients was found to be higher than their non-diabetic controls, but no significant difference could be found between type 2 diabetic male patients and their non-diabetic controls by US. Our results might indicate a possible impact of diabetes on the ATT depending upon gender, but other mechanisms may also contribute to thickening of Achilles tendon.

The influence of BCG immunisation on tuberculin reactivity and booster effect in adults in a country with a high prevalence of tuberculosis.

The relationship of age and previous BCG vaccination with tuberculin skin test (TST) reactivity was investigated to assess the interpretation of TST results in the adult population of Turkey, where there is a high prevalence of tuberculosis and a routine BCG vaccination programme. The influences of age and BCG vaccine status on booster reaction were also evaluated. TST was applied (5 tuberculin units of purified protein derivative intradermally) to two healthy adult groups, namely 98 medical students and 187 elderly people in a retirement home. The TST was considered positive if an induration > or = 10 mm in diameter was produced. Subjects (41 elderly people and 39 students) with a reaction < 10 mm in diameter were retested 1 week later. There was no significant difference between the students (59.1%) and elderly subjects (58.8%) with respect to positive TST response. No influence of BCG scars on TST reactivity was observed in either group. The booster effect was seen more commonly in the elderly, but the presence of a BCG scar did not influence the booster effect in either group. It was concluded that a positive TST response and booster reaction in adults in high-prevalence countries may be caused by latent tuberculosis rather than previous vaccination.

A study on the prevalence of accessory auricle anomaly in Turkey.

OBJECTIVE: Accessory auricular anomaly is a small elevation of skin containing a bar of elastic cartilage localized most commonly just anterior to the tragus or ascending crus of the helix. The anomaly may exist isolated or may be associated with other congenital anomalies of the first arch. The purpose in this study is to detect prevalence of accessory auricle in Turkey and find out whether it is associated with other craniofacial anomalies or hearing loss. METHODS: The study was performed on 850 children from the age of 7 to 9 during a screening program in primary schools. Complete otolaryngologic examination and acoustic reflectometry measurements were performed on all the children. Full physical examination, tympanometric and audiometric evaluation and EEG measurements were added to the cases with accessory auricle anomaly. RESULTS: Among 850 children examined, four had accessory auricle anomaly and prevalence of the anomaly was calculated as 0.47% (95% confidence interval (CI), 0.13-1.20%). Children were developmentally normal, and no other congenital craniofacial or systemic anomaly was detected in any of the cases. Further, tympanometric, audiometric evaluations and EEG tests were in normal limits. CONCLUSIONS: In this study, the prevalence rate of the condition was calculated as 0.47%. Although one study from China reported this prevalence as 0.22%, the difference between the reported prevalances was not statistically significant. Further, although external ear anomalies may present together with cranifacial anomalies and neurologic disorders like epilepsy, neuromotor retardation and EEG disorders, in our cases, mental and motor development was normal and epilepsy history or abnormal EEG patterns do not exist. On the other hand, no hearing loss was found to be associated with accessory auricles.

Gastrointestinal quality of life in patients with symptomatic or asymptomatic cholelithiasis before and after laparoscopic cholecystectomy.

BACKGROUND: There is an ongoing need, from both the medical and the economic perspective, for a more accurate definition of the influence of symptomatic or asymptomatic gallstone disease on gastrointestinal symptomatology, as well as on the health of the individual in general. METHODS: Using the Gastrointestinal Quality of Life Index (GIQLI), 37 symptomatic and 30 asymptomatic gallstone patients were evaluated at admission to the hospital and again 4 months after undergoing an uneventful laparoscopic cholecystectomy (LC). RESULTS: Postoperatively, significant increases in the total GIQLI score were noted in both the symptomatic group (113.42 +/- 21.9 vs 80.32 +/- 19.1 preoperatively; p < 0.05) and the asymptomatic group (96.37 +/- 14.26 vs 113.30 +/- 15.22; p < 0.05). For the subgroups of items, the core symptoms and the physical, psychological, and disease-specific items improved significantly in both groups in the postoperative period (p < 0.05 for all comparisons), but only the symptomatic group achieved a significant improvement in the subgroup of social items (p < 0.05). Negative correlations were found in both the symptomatic and asymptomatic groups between the preoperative GIQLI scores and the improvement seen after LC (r = -0.70 and r = -0.49, respectively). CONCLUSION: Gallstone disease has a profoundly negative impact on quality of life, especially in symptomatic patients with a history of biliary colic attacks and/or the complications of the disease. Although the condition is not equally distressing for the asymptomatic group of patients without such a history, uncomplicated LC improves the quality of life significantly in both groups. Gallstone patients with lower GIQLI scores are more likely to benefit from LC.

Differential diagnosis of solid breast lesions: contribution of Doppler studies to mammography and gray scale imaging.

OBJECTIVE: To assess the role of Doppler sonography when used in conjunction with mammography and gray scale sonography in differentiating solid breast lesions and to find out whether lesion size is a limiting factor for Doppler evaluation. METHODS: One hundred twelve lesions (70 malignant and 42 benign) detected with mammography and sonography were prospectively examined with color, power, and pulsed Doppler sonography. Vascularity was analyzed morphologically (vessel location, form, and color tone) and semiquantitatively (by spectral indices) to determine the valuable diagnostic flow characteristics. The lesions were classified by 2 observers as benign or malignant on the basis of each diagnostic technique (namely, a combination of mammography and gray scale sonography, presence or absence of blood flow, morphologic flow analysis, and spectral flow analysis). The results were compared with the histologic diagnosis in 105 lesions and with the clinical and radiologic diagnosis after at least 2 years of follow-up in 7 lesions. RESULTS: The sensitivity and specificity of the mammography-gray scale sonography combination were 98.6% and 76.2%, respectively. Neither morphologic nor spectral Doppler analysis proved to be successful on its own, however, information obtained from investigated morphologic and spectral flow features increased the specificity of mammography and gray scale sonography for lesions 10 mm and smaller (from 88.9% to 100%) and those larger than 10 mm (from 70% to 96.6%). CONCLUSIONS: Our data show that Doppler sonography is a beneficial adjunct to mammography and gray scale sonography for solid breast lesions 10 mm and smaller and those larger than 10 mm.

Tetanus immunization in pregnant women: evaluation of maternal tetanus vaccination status and factors affecting rate of vaccination coverage.

The objectives of this study were to determine the tetanus vaccination status for pregnant women, and to examine the effects of various factors on tetanus toxoid (TT) vaccination coverage during pregnancy in reproductive-age women. Four-hundred and ninety-three postpartum women who had live births at a hospital in Ankara were interviewed and information was collected on the mothers' sociodemographic characteristics, TT vaccination history, and prenatal care during the pregnancy studied. The rates for no vaccination, one-dose vaccination, and two-dose vaccination were 53.3%, 18.9%, and 27.8%, respectively. The vaccinated women (with at least one dose) were significantly younger, of lower parity, and had attended more prenatal care visits than the unvaccinated women. Of the women who attended at least one prenatal care check-up, only about half were vaccinated. Significantly more rural women were vaccinated against tetanus than urban women. Current vaccination rates with TT during pregnancy were found to be well below universal levels. Turkey needs to launch effective mass media campaigns that target urban and suburban populations, and inform and motivate women to request vaccination against tetanus.

Prevalence of stress urinary incontinence in both sexes at or after age 15 years: a cross-sectional study.

PURPOSE: We determine the prevalence of stress urinary incontinence among males and females at or after age 15 years in an education and research health district. MATERIALS AND METHODS: During a personal interview questionnaires were given to a total of 2,053 people at or after age 15 years in an education and research health district near Ankara, Turkey. In addition to the particular questions about stress incontinence, the medical history, including congenital or acquired diseases of clinical significance, operations and details relevant to positive findings were obtained. Groups with or without stress incontinence were compared in regard to age and sex, and parity in women. Subgroups that emerged as to the presence of nocturia and/or urgency incontinence were examined in regard to systemic diseases, operations, congenital anomalies and regular medications. RESULTS: A total of 229 people (11.1%) had stress incontinence, with a female predominance of 20.8% versus 1.0% (p <0.05). People 65 years old or older experienced stress incontinence 6.24 times more than those in the 15 to 24-year age group. In contrast, females had increasing stress incontinence prevalence by age as noted by relevant odds ratios. Stress incontinence prevalences among women in the 35 to 44 and 45 to 54-year age groups were about 39 and 35 times higher than those of men in the corresponding age groups. As expected the incontinence prevalences increased with the number of births in women. Nocturia was absent in 50.2% of all subjects, whereas 26.7% reported nocturia at all times and 23.0% had nocturia sometimes. Persistent nocturia was present in 21.1% of males and 32.1% of females. Persistent nocturia and urgency were apparently greater in patients with systemic diseases and/or those who had undergone surgery. Urgency incontinence was present in 9.7% of the entire population with a distinct female predominance of 16.3% versus 2.7%. CONCLUSIONS: Stress incontinence occurred in both sexes at or after age 15 years with a female predominance. The prevalence of stress incontinence increases with age and parity in women. Urgency and nocturia are more prevalent in people with systemic diseases and those who have undergone previous pelvic or neurosurgical operations.

Tetanus immunization in pregnant women. Serum levels of antitetanus antibodies at time of delivery.

The objective of this study was to determine the tetanus immunity status of pregnant women at the time of delivery according to tetanus toxoid (TT) vaccination coverage during their most pregnancy. The serum anti-tetanus antibody levels of 493 mothers who had live births at a hospital in Ankara were determined by enzyme-linked immunosorbent assay (ELISA). Protected women were defined as those with serum antibody levels > or = 0.6 IU/ml. Overall, 69.0% of mothers had protective tetanus antibody titers at the time of delivery. The rates of protection for mothers who had received no vaccination, one TT dose, or two TT doses during pregnancy were 46.4, 93.5, and 95.6%, respectively. Vaccinating every pregnant woman with at least one dose of TT would be an affordable and effective way to protect against neonatal tetanus, and would be a step toward eliminating the deaths that continue to occur due to this preventable disease in Turkey.

Alterations in cardiac flow parameters in patients with polycystic ovarian syndrome.

The aim of this study was to examine the echocardiographic profiles of patients with polycystic ovarian syndrome (PCOS). Serum concentrations of follicle stimulating hormone, luteinizing hormone, androstenedione, free testosterone, prolactin, DHEA-SO(4) and 17-OH-progesterone, lipid profile (high and low density lipoproteins, triglyceride and total cholesterol) and basal and total insulin after a glucose tolerance test were measured in 35 patients with PCOS and 35 healthy controls matched for body mass index. Doppler, two dimensional M mode echocardiography was performed for the following indices: isovolumetric relaxation time (IVRT), E wave duration time (EVT), A wave duration time (AVT), E wave deceleration time (DT), peak early diastolic flow velocity (PEV), peak late diastolic flow velocity (PAV), E wave velocity time integral (FVI-E), A wave velocity time integral (FVI-A), atrial filling fraction (AFF), ejection fraction (EF), pre-ejection time (PEP), ejection time (ET) and aortic flow velocity time integral (FVI). Androstenedione, free testosterone, low density lipoproteins and cholesterol concentrations were significantly higher in patients with PCOS. There was no difference in basal and total insulin concentrations. IVRT, AVT, FVI-A, AFF, and PEP were higher in patients with PCOS, while PEV, FVI-E, EF, ET, EVT and EVT/AVT were higher in the control group. There was a positive correlation between basal insulin values and IVRT, and between total insulin values and EF. These changes are consistent with a non-restrictive type of diastolic dysfunction and left ventricular stiffness. PCOS may lead to diastolic dysfunction via hyperinsulinaemia and male type dyslipidaemia.

[A new modification of the neovagina reconstruction with peritoneum technique]. / Eine neue Modifikation bei der im Peritoneum verwendeten Neovagina-Bildungstechnik.

There are several surgical methods designed to construct a vagina when it is congenitally absent. Davidov has described a technique for correcting this condition, using the pelvic peritoneum to line the vaginal space. We performed new modifications to prevent disadvantages of this technique. An operative vagina was constructed in eight patients with vaginal agenesis, the vaginal surface were covered, using parietal peritoneum flaps with abdominovaginal approach. One year later, we found that four of them had an anatomically and functionally sufficient vagina. The remaining four patients can't be controlled yet, because not enough time has passed after the operation.

[Carcinoma of a Davydov neovagina]. / Karzinom in einer Davydov-Neovagina.

Congenital absence of vagina is a very rare anomaly and treatment is surgical. As this anomaly is a rare condition, carcinoma arising in the neovagina is also rare. Optimal treatment of this malignancy has not yet been determined. A carcinoma in the Davydov neovagina is reported upon with a review of the literature.
