Severe osteomalacia in a patient with idiopathic chronic pancreatitis.

We report a 30-year-old woman who was confined to a wheelchair because of severe myopathy. She was first seen by a neurologist because of a convulsive syndrome of unknown etiology when she was nine. She was started on anticonvulsive drugs but the drug was stopped when her serum calcium level was found to be very low. She had a history from childhood of steatorrhea and abdominal pain after a fatty meal and became vegetarian at age five years. She worked in a hospital as a nurse and at home her living room received no direct sunlight. As a result of these conditions osteomalacia progressed. We believe an awareness of chronic pancreatitis (CP) during childhood could have prevented the consequences of the disease in this case.

Value of petrosal sinus sampling: coexisting acromegaly, empty sella and meningioma.

Simultaneous occurrence of an intracranial meningioma and a growth hormone (GH)-producing pituitary adenoma is exceedingly rare, as is coexistence of an empty sella and acromegaly. We report all these rare entities in the same patient. We evaluated the role of inferior petrosal sinus sampling for lateralisation of an adenoma in this patient.

Concomitant association of thyroid sarcoidosis and Graves' disease.

OBJECTIVE: Graves' disease (GD) with sarcoid involvement of the thyroid gland has rarely been reported. METHOD: We report a case of GD with thyroid sarcoidosis in a 28-year-old woman. Thyroid function was assessed by triiodothyronine (T(3)), thyroxine (T(4)), thyroid-stimulating hormone (TSH) and TSH receptor antibodies (TSH-R Ab). Thyroid scintigraphy, ultrasound and fine-needle aspiration biopsy were performed. The patient underwent surgery. RESULT: The patient had a nodular goiter. Serum T(3), T(4) and TSH-R Ab levels were elevated with suppressed TSH level. Scintigraphy showed diffuse activity as seen in GD, and ultrasound revealed that parenchyma was heterogenous. Sarcoidosis was discovered on routine chest X-ray. Although no sarcoid involvement was found on specimen, the thyroid gland showed non-caseating granulomas on histology. CONCLUSION: Since sarcoid involvement of the thyroid gland can cause hypofunction, we report the uncommon infiltration of sarcoidosis with hyperthyroidism.

Sunlight exposure and vitamin D deficiency in Turkish women.

Vitamin D is an essential steroid involved in bone metabolism, cell growth, differentiation, and regulation of the minerals in the body. The main sources of this vital vitamin are adequate diet and photosynthesis in the skin. The aim of this study was to investigate the efficiency of vitamin D synthesis in 48 premenopausal women (14-44 years) in relation to three different types of dressing in summer. Women in the first group (Group I) dressed in a style which exposed the usual areas of the skin to sunlight; women in the second group (Group II wore traditional clothing with the skin of the hands and face uncovered, while the third group (Group III) dressed in traditional Islamic style, covering the whole body including hands and face. Serum 25OHD levels of Group I, Group II, and Group III were 56+/-41.3 nmol/l, 31.9+/-24.4 nmol/l, 9+/-5.7 nmol/l, respectively (Group I vs Group III, p<0.001; Group II vs Group III, p<0,03; Group I vs Group II, p>0.05). Vitamin D levels were low in 44 percent of the Group I and 60% of the Group II, which suggested that sun exposure of skin areas of hands and face may partially provide vitamin D synthesis, but may not be enough to eliminate vitamin D deficiency. All the patients in group III had vitamin D levels below normal. This study emphasizes the necessity of vitamin D fortification of food even in a sunny country where some people may not be exposed to sunlight because of inappropriate clothing or an indoor-life.

The effect of methimazole on the oxidant and antioxidant system in patients with hyperthyroidism.

The present study was designed to evaluate the changes in the plasma lipid peroxidation and antioxidant system in 15 adult volunteer patients in hyperthyroid and euthyroid states. In these patients, plasma concentrations of lipid peroxides were decreased and, ascorbic acid and vitamin E levels were significantly increased in euthyroid status in comparison to hyperthyroid status. A significant increase in the plasma GPx activity (P < 0.01) and a decrease in GST (P < 0.001) was observed after euthyroidism was sustained with methimazole therapy. In conclusion, hyperthyroidism tends to enhance lipid peroxide content and an increase in GST and decreases in GPx, vitamin E and ascorbic acid levels accompany to this change in the plasma. The achievement of euthyroidism led an improvement in these parameters.

Scintigraphic varieties in Hashimoto's thyroiditis and comparison with ultrasonography.

The scintigraphic findings in Hashimoto's thyroiditis are highly variable and can mimic any thyroid abnormality. In this study, we compared the scintigraphic findings with ultrasonography in 48 patients with Hashimoto's thyroiditis. Thyroid scintigrams revealed diffuse hyperplasia in 12 patients, multinodular goiter in 20 patients and a solitary nodule in 16 patients (toxic adenoma, n = 1; hypoactive nodule, n = 4; hyperactive nodule with no suppression, n = 3; normoactive nodule, n = 8). Ultrasonography revealed diffuse hyperplasia in 19 patients, multinodular goiter in 20 patients and a solitary nodule in 9 patients. The thyroid scan and ultrasonography revealed the same findings of diffuse hyperplasia in 12 patients and multinodular goiter in 20 patients. Of the 16 patients with a solitary nodule on scintigraphy, only 9 showed the same finding on ultrasonography, with the other 7 showing diffuse hyperplasia. The difference in nodularity between thyroid scanning (74.9%) and sonography (60.4%) has been attributed to pseudonodularity in Hashimoto's thyroiditis. In conclusion, our results confirmed that Hashimoto's thyroiditis can mimic any thyroid abnormality, including diffuse hyperplasia, nodular goiter and multinodular goiter on scintigraphy. Therefore, scintigraphy, ultrasonography and serum thyroid hormone estimation alone may not be helpful for the final diagnosis of Hashimoto's disease. To eliminate unnecessary surgical intervention, all patients should be evaluated by means of physical examination and thyroid autoantibodies, in addition to a thyroid scan, ultrasonography, serum thyroid hormones and fine-needle aspiration biopsy when necessary.

Propylthiouracil-induced cutaneous vasculitis.

Cutaneous reactions to propylthiouracil and methimazole occur in 3%-5% of adults. Generalized maculopapular and papular purpuric eruptions are perhaps the most common thionamide-induced reactions. We report 3 patients who developed cutaneous vasculitis which is a rare and serious side-effect during antithyroid drug therapy. The observation of cutaneous vasculitis during administration of propylthiouracil suggested that clinical awareness of this complication should be of considerable importance.

Association of Fallot Tetralogy with Carney's complex.

The Carney complex is an inherited, autosomal disease of multicentric tumors in many organs. Some components of Carney's complex are cardiac myxoma, spotty pigmentation, and endocrine overactivity. Primary pigmented nodular adrenocortical dysplasia (PPNAD) is an exceedingly rare cause of Cushing's syndrome in infants, children, and young adults. PPNAD occurs sporadically or as part of a familial syndrome called Carney's complex. Up to our knowledge, the association of Fallot Tetralogy with Carney's complex has not been previously reported. We presented, a 20-year-old woman, who had been operated for Fallot Tetralogy at the age of 3 years, had Carney's complex, i.e. left atrial myxoma, two facial spotty pigmented areas, and PPNAD.
