Gingival enlargement in acromegaly.

In this study, we investigated gingival enlargement in patients with acromegaly as a component of the disease. Eleven patients (5 males, 6 females) were evaluated. Diagnosis was confirmed with typical clinical features and laboratory. Oral examinations were carried out by the same periodontist. During the examination, plaque index, gingival index, probing pocket depths, and gingival enlargement values were evaluated. Duration of the disease was between 0.2 and 13 yr. Seven patients had pituitary macroadenomas and four had microadenomas during their initial diagnosis. Only one patient was newly diagnosed. The other patients had previously undergone surgery. Gingival enlargement was found in eight patients. Seven patients with gingival enlargement also had prognathism, and one patient had prognathism associated with gingival enlargement. These findings demonstrate that acromegaly that results in overgrowth in various organs should be considered one of the causes of gingival enlargement.

Relationship between electroneurographic changes and serum ubiquitin levels in patients with type 2 diabetes.

OBJECTIVE: The aim of the present study was to investigate any relationship between serum ubiquitin levels and electroneurographic changes in peripheral nerves for patients with type 2 diabetes. RESEARCH DESIGN AND METHODS: The study involved 34 patients (19 men, 15 women; mean age 46 +/- 13 years) with type 2 diabetes. Serum ubiquitin values were measured by sandwich enzyme-linked immunosorbent assay Measurement of nerve conduction velocity (NCV) was performed on three motor (median, tibial, and peroneal) and three sensory (median, ulnar, and sural) nerves. The value of motor compound muscle action potential (CMAP) was obtained from the sum of median, tibial, and peroneal motor nerve amplitudes, and sensory compound nerve action potential (CNAP) was computed as the sum of median and ulnar sensory nerve amplitudes. RESULTS: Patients with diabetes were divided into three groups: group 1 (n = 8) had normal electroneurography results, group 2 (n = 8) had slowed NCV, and group 3 (n = 18) had low values of motor CMAP and/or sensory CNAP as well as slowed NCV. Mean ubiquitin level in group 3 (20.4 +/- 2.9 ng/dl) was significantly higher than that in group 1 (11.2 +/- 1.1 ng/dl, t = 11.5, P < 0.0001) and group 2 (13.2 +/- 2.7 ng/dl, t = 5.9, P < 0.0001). Serum ubiquitin levels were inversely correlated with motor CMAP (r = -0.68) and sensory CNAP (r = -0.61) values. CONCLUSIONS: The results of this study indicate that there could be a relationship between the diminished amplitudes of axons of the peripheral nerve and the increase in serum ubiquitin levels in patients with type 2 diabetes. Further studies are required to confirm this relationship.

Thyroid abnormalities in lithium-treated patients with bipolar affective disorder.

The thyroid functions of 42 subjects with bipolar affective disorder receiving regular lithium therapy were analysed and their thyroid glands were examined by ultrasonography. Following the receipt of lithium therapy (duration 4-156 months), three subjects displayed subclinical hypothyroidism (7.1%), three subclinical hyperthyroidism (7.1%) and one hyperthyroidism (2.4%). Moreover, goitre was detected in 16 (38.1%) subjects. An increase in the conversion of free thyroxine (T4) to free tri-iodothyrosine (T3), which is an indication of mild thyroid dysfunction, was identified in 20 (47.6%) subjects, and was mostly seen in male subjects under 40 years of age and in those having weight gain. In conclusion, some thyroid dysfunctions were observed in the patients treated with lithium.

A hydatid cyst of the thyroid gland.

Echinococcosis, although eradicated in many countries, is still widespread in communities in which agriculture is dominant, and cystic hydatidosis is a significant public health problem in regions where echinococcosis is endemic. Hydatid cysts may be found in almost any part of the body, but most often in the liver and lungs. Other organs affected occasionally include the brain, muscle, kidney, bone, heart and pancreas. This report documents a rare case with a cystic nodule in the thyroid detected by ultrasonography. The patient was a 40-year-old woman with an euthyroid multinodular goitre. Ultrasonography revealed a cystic nodule, and the ultrasonic appearance of the cyst liquid showed multiple echoes, suggesting that the nodule could be a hydatid cyst. Bilateral subtotal thyroidectomy was performed. Postoperative examination of the nodule showed it to be a solitary primary thyroid hydatid cyst.

The effects of high haematocrit levels on glucose metabolism disorders.

There has been only limited research investigating the possible association between raised haematocrit levels, glucose intolerance and type 2 diabetes. In the present study, we explored the association between high haematocrit levels and impaired glucose tolerance by performing oral glucose tolerance tests in 46 patients with chronic obstructive pulmonary disease and no previous history of diabetes mellitus or glucose intolerance. A glucose metabolism disorder was observed in 12 (26%) patients (type 2 diabetes in six patients and impaired glucose tolerance in a further six). There was a significant association between high haematocrit levels and the presence of a glucose metabolism disorder, which was independent of other risk factors. High haematocrit levels may be an independent risk factor for type 2 diabetes and impaired glucose tolerance.
