Malignant fibrous histiocytoma metastatic to adrenal gland: a case report.

We report on a rare case of a 63-year-old male with malignant fibrous histiocytoma (MFH) metastatic to the right adrenal gland, first diagnosed with fine needle aspiration (FNA) biopsy. The cytological and immunocytochemical study indicated a malignant neoplasm of mesenchymal origin with characteristics of MFH. The patient was then operated on and the pathological and immunohistochemical findings confirmed the cytological diagnosis. FNA becomes more widely useful for the diagnosis of non-palpable masses. It is worth noting that the fluid-based thin-layer "Thin Prep" method provides the possibility to apply immunocytochemical stainings in FNA cytologic material, especially in cases where the material is inadequate.

Bone mineral density of patients with thalassemia major: four-year follow-up.

The purpose of this study was to evaluate the bone mineral density (BMD) of 50 patients aged 9-28 years, with thalassemia major and to assess the alterations of bone density in a 4-year follow-up study. They were measured with a DPX densitometer at the lumbar spine and femur area and divided into three groups: preadolescents, adolescents, and adults. All patients received calcium and vitamin D supplements, and 8 of the 50 received hormone replacement therapy (HRT). All patients had a significantly lower BMD compared with healthy subjects. Mean values of lumbar BMD of the three groups were 1.3, 2, and 3 standard deviations (SDs) lower than those of healthy subjects of the same age. All adolescent patients with normal gonadal function and those who received HRT showed an increase in BMD during the period of the study. Adult patients also showed an increase in bone density as long as the treatment lasted. However, adolescent and adult patients who had hypogonadotropic hypogonadism but could not get therapy showed a decrease in bone density. BMD of patients with thalassemia major shows a good index of bone status which should be evaluated, especially for the determination and follow-up of therapy.

Growth hormone, oestradiol, progesterone and testosterone concentrations in follicular fluid after ovarian stimulation with various regimes for assisted reproduction.

Follicular fluid samples and oocytes were obtained from 75 women (87 cycles), who participated in an assisted conception programme. Determinations of the concentration of oestradiol, progesterone, testosterone and growth hormone were performed in all follicular fluid samples. Patients were stimulated with the following regimes: group A (24 cycles, 94 samples), human menopausal gonadotrophin (HMG) (three ampoules/day) and human chorionic gonadotrophin (HCG); group B (23 cycles, 53 samples), HMG/HCG with prednisolone (7.5 mg/day) after cycle programming with oral contraceptives; group C (40 cycles, 60 samples), buserelin with HMG/HCG. Oestradiol concentrations (mean +/- SEM) were significantly higher (P < 0.05) in group A (320.1 +/- 27.3 ng/ml) and those of growth hormone in both groups A and C (3.8 +/- 0.2 and 3.2 +/- 0.15 ng/ml, respectively), as compared to the other groups, whereas progesterone and testosterone concentrations were similar in all groups. The mean concentrations of oestradiol, progesterone, testosterone and growth hormone were significantly higher (P < 0.01) in follicular fluid with oocytes of intermediate maturity than with mature oocytes (382.5 ng/ml, 7847.5 ng/ml, 1704.5 ng/dl and 3.7 ng/ml versus 217.8 ng/ml, 5488.4 ng/ml, 1313.6 ng/dl and 2.7 ng/ml, respectively). On the other hand, only oestradiol concentrations were significantly higher in follicular fluid of fertilized compared to non-fertilized oocytes. Concentrations of the other hormones analysed, except growth hormone, were similar in follicular fluid from pregnant and non-pregnant women after assisted reproduction. Growth hormone, on the other hand, was significantly lower (P < 0.05) in follicular fluid from pregnant compared to non-pregnant women (2.8 versus 3.5 ng/ml).(ABSTRACT TRUNCATED AT 250 WORDS)
