Adrenal and pituitary incidentalomas in a case of Cushing's syndrome.

Cushing's syndrome is a pathological condition where surgery may be lifesaving. The proper diagnosis depends upon the hormonal pattern of the patient, various dynamic tests and imagistic investigations. We report a case of a patient with Cushing's syndrome, with bilateral adrenal tumors and a pituitary microadenoma.

Perioperative management difficulties in parathyroidectomy for primary versus secondary and tertiary hyperparathyroidism.

Background: In patients with hyperparathyroidism, parathyroidectomy is the only curative therapy. Anaesthetic management differs function of etiology (primary vs. secondary or tertiary hyperparathyroidism) and surgical technique (minimally invasive or classic parathyroidectomy).

Virilising Sertoli-Leydig cell tumour associated with thyroid papillary carcinoma: case report and general considerations.

We present a case of a Sertoli-Leydig cell tumour manifested with progressive hirsutism, frontal alopecia and secondary amenorrhea in a 46-years-old female, evolving for 6 years until presentation. Serum testosterone level was 8.01 ng/ml and gonadotropic hormones were LH 8.

Pheochromocytoma--from endocrinologist to surgeon.

We report the case an asymptomatic patient who underwent left adrenalectomy for a incidentally discovered large, cystic adrenal tumor. The patient presented no hypertension before or during the intervention. The hystopatological exam revealed a pheochromocytoma, with signs suggesting malignancy.

Electroretinography and temporal aspects in macular dystrophy.

In a family with cone-rod dystrophy of autosomal recess inheritance, the diagnosis was established by characteristic abnormalities of the ERG, which demonstrates cone responses reduced in amplitude and delayed in implicit time, and rod delayed implicit time in two sisters with macular degeneration. The abnormalities of the implicit time are seen also in two other sisters of the propositi, who are clinically normal. The hypothesis that they are only capable to transmit the gene defect to their offspring is advanced.

Retinal involvement in a case of nephronophthisis associated with liver fibrosis Senior-Boichis syndrome.

Electroretinographic and electroencephalographic studies were conducted in a 12-year-old boy with nephronophthisis, chronic hepatic fibrosis, mental retardation and tapetoretinal degeneration (Senior-Boichis syndrome). Markedly reduced ERG amplitudes and flat oscillatory potentials were found in the proband. Delayed scotopic implicit time and reduced amplitudes of the beta-wave were found in the mother's ERG.

The effects of acetazolamide on the human electroretinogram.

The effects of acetazolamied on the cerebral circulation and metabolism was previously shown to be due to a raised PCO2 in brain tissue. The effects of the drug on the human electroretinogram (ERG) are investigated in fifteen human volunteer subjects. A significant increase in the b-wave was found.

Temporal aspects of electroretinography in patients with myotonic dystrophy.

Electroretinographic records of eight patients with myotonic dystrophy (Steinert's) in ganzfeld and single-flash stimulation showed a decrease of the b-wave amplitude and a delayed scotopic implicit time.

["Implicit time". Practical and theoretical aspects].

52 normal subjects were studied as control for our "Ganzfeld" method of E.R.G.
