This study aimed to determine the normal size of the male external genital organs and anogenital distance in human fetuses during the fetal period through the anatomic morphometric method. The study was performed on 104 spontaneously aborted human male fetuses aged between 10 and 39 weeks of gestation. Fetuses were divided into groups according to gestational weeks, months, and trimesters. Parameters belonging to the male external genital organs were measured, including penile length and width, transverse scrotal diameter, anterior–posterior scrotal diameter, the distance from the anterior and posterior aspect of the penis to the center of the anus, and the anogenital distance. The mean of each parameter was computed by gestational weeks, months, and trimester groups, and data were presented as mean ± standard deviation. The mean of each parameter increased with gestational age, and statistically significant differences were observed between trimester groups. A high correlation was also determined between gestational age and the parameters measured.

PurposeThe aim of this study was to investigate the morphometric development of the extraocular muscles in the fetal period and to create a modified Tillaux spiral.MethodsWe dissected 157 fetal eyes (82 right eyes, 75 left eyes) obtained from 79 fetuses (46 boys, 33 girls) between 13 and 40 weeks of gestation. The tendon widths of the extraocular muscles and the distances of the tendon attachment sites to the limbus were measured. Tillaux's modified spiral was created.ResultsIn addition to the rectus muscles, we added tendon widths and tendon–limbus distances of the upper (SO) and lower (IO) obliques to the modified Tillaux spiral. When tendon widths were compared between genders, no statistically significant difference was observed. When tendon widths were compared between the sides, it was determined that SO was more in the left eye, whereas other extraocular muscles were more in the right eye. There was no statistically significant difference between genders when the distances of tendon attachment sites to the limbus were compared. There was no statistically significant difference in SO and IO values between the sides. There was a statistically significant difference in the rectus muscles and this difference was found to be higher in the right eye.ConclusionWe think that the findings obtained will contribute to disciplines such as fetopathology, obstetrics, ophthalmology and plastic surgery and to future studies on this subject.

The aim of this study was to evaluate the autonomic function in patients with essential tremor (ET). Thirty-one adult patients with ET and 26 healthy controls were enrolled in the study. The electrophysiological evaluations of the autonomic nervous system function were performed by sympathetic skin response (SSR) and R–R interval variation (RRIV) tests. The mean latency of SSR in ET patients was significantly delayed compared with the controls ( P  = 0.01). The mean amplitude of sympathetic skin response was significantly lower in ET patients in comparison to the controls ( P  = 0.001). No differences were found in mean RRIV values in both group subjects. Sympathetic dysfunction may occur in patients with ET. This may be easily demonstrated by SSR tests.
