The role of the resistive index in Hashimoto's thyroiditis: a Sonographic pilot study in children

OBJECTIVE: The role of Doppler ultrasonography in the diagnosis of diffuse thyroid diseases is not well established. In particular, Doppler ultrasonography findings in children with Hashimoto's thyroiditis are very limited. We examined gray-scale and Doppler ultrasound findings in Hashimoto's thyroiditis in children in an attempt to understand the feasibility of future prospective controlled studies. MATERIALS AND METHODS: Twenty-one children with newly diagnosed Hashimoto's thyroiditis were recruited in the study. The patients were euthyroid or had subclinical hypothyroidism at the time of the ultrasonography examination. According to the color Doppler scale developed by Schulz et al., thyroid glands were classified into four patterns based on visual scoring and the mean resistive index (RI), which was calculated via measurements from both lobes, and these results were compared with gray-scale findings. RESULTS: The mean RI value, calculated as the mean of the RI values of both lobes obtained from each patient, was found to be 0.57 ± 0.05 (range 0.48-0.67) cm/sn. The distribution of thyroid classifications was as follows: Pattern 0, n = 7; Pattern I, n = 6; Pattern II, n = 4; and Pattern III ("thyroid inferno"), n = 4. The mean RI values in patients with normal or near-normal gray-scale findings (n = 10) and patients with more substantial gray-scale changes (n = 11) were not significantly different and were lower than the values in normal children previously presented in the literature. CONCLUSION: The results indicated that the RI may be more sensitive than other ultrasound parameters for the diagnosis of Hashimoto's thyroiditis

IS TESTICULAR MICROLITHIASIS A REALLY INNOCENT CONDITION? ITS EFFECTS ON ONCOLOGICAL OUTCOMES OF GERM CELL TESTICULAR CANCER: AN OBSERVATIONAL STUDY

OBJECTIVES: Although it is a well known condition that presence of testicular microlithiasis (TM) with the co-occurrence of specific risk factors such as history of previous germ cell testicular cancer (GCTC), infertility, undescended testes or atrophic testes have high risks for GCTC development,TM is still a controversial topic. Its effects on oncological outcomes have still not been investigated in detail. In this study, we aimed to evaluate whether the presence of TM has an effect on GCTC prognosis and oncological outcomes

The mean RI values in patients with normal or near-normal gray-scale findings (n = 10) and patients with more substantial gray-scale changes (n = 11) were not significantly different and were lower than the values in normal children previously presented in the literature.

Intra-Familial Incidence and Characteristics of Hot Water Epilepsy

Objective: To assess the clinical features of several members of the same family diagnosed with both hot water epilepsy (HWE) and cerebral lesions. Methods: Age at onset and types of seizure, precipitating factors, EEG findings, and neuroimages were evaluated. Results: The family consisted of' six generations, including one consanguineous parent. Of eight family members diagnosed with epilepsy, seven suffered from HWE. Age at onset of seizures ranged within childhood. Seven patients with HWE experienced complex partial seizures, with or without secondary generalization; one experienced simple partial seizures as well as complex partial seizures. Three patients experienced spontaneous seizures as well as HWE. Interictal EEG revealed abnormalities in two patients. Magnetic resonance imaging revealed cerebral lesions in one patient, probably attributable to ischemic changes. Magnetic resonance images were consistent with findings of ischemic gliosis in two patients, and either demyelinating or ischemic gliosis in one patient. Conclusions: Descriptions of HWE families with different ethnic backgrounds may permit more definite conclusions regarding the mechanisms epileptogenesis, and the genetic defects that underlie this disease

Effects of testicular dysgenesis syndrome components on testicular germ cell tumor prognosis and oncological outcomes

Purpose: To evaluate whether components of Testicular Dysgenesis Syndrome (TDS) affect testicular germ cell tumor (TGCT) prognosis and oncological outcomes. According to the hypothesis called TDS; undescended testis, hypospadias, testicular cancer and spermatogenic disorders share the same risk factors and have a combined fetal origin. Materials and Methods:We retrospectively evaluated the stages and oncological outcomes of 69 patients who underwent radical orchiectomy between January 2010 and December 2014 due to TGCT in our department. The presence of undescended testis, hypospadias and semen parameters disorders were recorded according to anamnesis of patients. Results: Among 69 patients with TGCT, only 16 (23.1 %) had TDS. Significantly higher rate of TDS (36.1 % vs. 9.1 %) was observed at the advanced stages of TGCT(p=0.008). In the TDS group, the rates of local recurrence (50 % vs. 11.3%, p<0.001), distant metastasis (93.6% vs. 3.8%, p<0.001) and cancer-spesific mortality (87.5% vs. 3.8%, p<0.001) were found significantly higher than those without TDS. The predicted time for recurrence-free survival (13.70 +/- 5.13 vs. 100.96 +/- 2.83 months, p<0.001) metastasis-free survival (13.12 +/- 4.21 vs. 102.79 +/- 2.21 months, p <0.001) and cancer-specific survival (13.68 +/- 5.38 vs. 102.80 +/- 2.19 months, p<0.001) were also statistically lower in this group. Conclusions: According to our preliminary results, there is an apparent relationship between TDS and tumor prognosis. Even if the components of TDS alone did not contain poor prognostic features for TGCT, the presence of TDS was found as the most important independent predictive factor for oncological outcomes in both seminomas and nonseminomas as well as all patients with TGCT
