Sexual maturation in Turkish girls.

Ages of attainment of successive puberty stages of the breast, public hair and axillary hair and of menarche were established in a cross-sectional study of 1468 Turkish school girls in Istanbul. The subjects were grouped into four socioeconomic classes. Onset of secondary sexual characteristics and of menarche in the highest socioeconomic class were early as compared to other population groups. Mean ages of attainment for the initial stage of breast, pubic hair and axillary hair development were 9.8, 10.4 and 10.8 years respectively in this group. Mean menarcheal age was 12.36 +/- 0.01 years. All stages of breast, pubic hair and axillary hair and also menarche consistently occurred later in the lower socioeconomic classes as compared with the higher. The time intervals from onset to completion of secondary sexual characteristics were comparable to those reported for European girls for pubic and axillary hair development, but relatively longer for the development of the breast. They differed little between the socioeconomic classes.

Sexual maturation in Turkish boys.

Ages of onset and attainment of various stages of secondary sexual characters were assessed from cross-sectional data on 1530 city schoolboys in Istanbul, Turkey. The subjects were grouped into four socio-economic classes. Ages of onset of pubic hair (11.80 years), axillary hair (13.15 years), facial hair (14.45 years) and laryngeal development (13.37 years) were relatively early in the highest socioeconomic class and agreed with recent values reported for European boys. In lower socioeconomic classes there was a relative delay of onset and attainment of the subsequent stages of secondary sexual characters. Acne was encountered in a significant proportion of the boys and increased in frequency with age. Socioeconomic level had no effect on its frequency. Gynaecomastia, unilateral in nearly half of the instances, was encountered in 7.0 per cent of the subjects. The frequency of gynaecomastia was lower in class 1 boys.

Spinal cord compression due to Brucella granuloma.

Central Nervous System (CNS) involvement during the course of Brucella infection is a rare clinical condition. In this article, a patient with a progressive paraparesis syndrome with spasticity, who was treated by medical methods and surgical intervention is analysed. This patient suffered from spinal cord compression in the thoracal region caused by a Brucella granuloma. The patient had no evidence of systemic Brucella infection.

Amitraz poisoning in children: retrospective analysis of 21 cases.

The clinical and laboratory findings of 21 children with amitraz poisoning were evaluated retrospectively. Poisoning route, signs and symptoms of poisoning, duration of hospitalization and outcome were recorded. The mean age was 3.5 +/- 1.9 years and the ratio of males to females was 1.63. In all cases poisoning was via the oral route. The time from ingestion to onset of symptoms was 30-180 min. Drowsiness (100%) and loss of consciousness (100%) were the most common clinical findings, followed by vomiting (61.9%). Hypotension was observed in 66.7% of cases, bradycardia in 61.9%, respiratory depression in 42.9%, hypothermia in 9.3%, and 14.3% had generalized seizures responsive to diazepam. Hyperglycaemia and glycosuria were detected in 47.6% and 38.1% of cases, respectively. Minimally elevated transaminases and alkaline phosphatase levels were detected in 23.8% of cases. All patients recovered completely and were discharged within 1.0-5.2 days (mean, 2.1 +/- 1.1).

Pelvic ultrasound measurements in normal girls: relation to puberty and sex hormone concentration.

Pelvic ultrasonography was performed on 75 normal girls. Values were obtained for uterine length, fundal/cervical ratio (FCR), ovarian volume and sex hormones. The resultant data were grouped according to age and pubertal stage (Tanner). For uterine length, FCR and ovarian volume, the data were positively skewed, and the variance increased with age and pubertal stage (p < 0.001). The uterus underwent a regular increase in size and the corpus gradually became larger than the cervix. Uterine length, right ovary volume, FCR and hormones (serum estradiol, follicle-stimulating hormone and luteinizing hormone) showed a correlation with the Tanner score (p < 0.001). Although the correlations were significant, the best correlation was between pubertal stage and serum estradiol level.

Serum ferritin and hemoglobin levels of mothers and their newborns.

In this study, hemoglobin, serum ferritin, serum transferrin, transferrin saturation, serum iron and total iron-binding capacity were measured in venous blood taken from 52 primiparous mothers approximately one hour before delivery and in cord blood from their newborns after birth. The mean maternal serum ferritin level was 12.9 +/- 8.9 ng/ml. This value was lower than that of healthy women. The mean serum ferritin level of cord blood was 103.0 +/- 54.1 ng/ml. While we found no correlation between maternal and cord blood hemoglobin values, we observed a significant positive correlation between serum ferritin values in maternal and cord blood. Only the serum ferritin levels of mothers whose iron stores had been depleted were significantly reflected in their babies' levels (p < 0.001). There was no statistically significant difference in other parameters (p > 0.05). It is concluded that serum ferritin levels, which are affected earlier than hemoglobin levels, should be measured for the diagnosis of occult iron deficiency.
