Case Reports
Effects of growth hormone reduction in a patient with polycystic ovary syndrome complicated with acromegaly.
We report a rare case of polycystic ovary syndrome (PCOS) complicated with acromegaly due to a growth hormone (GH)-producing pituitary adenoma. Complete removal of the pituitary adenoma successfully reduced circulating levels of GH and insulin-like growth factor (IGF)-1, which, in turn, resulted in the amelioration of gonadal dysfunction, hyperandrogenism, lutenizing hormone hypersecretion, and severe insulin resistance. This clinical complication suggests that activation of systemic GH-IGF-1 axis is potentially involved in the development of PCOS.

We describe herein a case of thyroid storm with hypoglycemia and lactic acidosis-a rare complication of thyroid storm. The patient was a 50-year-old Japanese woman who suffered cardiopulmonary arrest an hour after hospitalization. ⋯ Thus, if atypical thyroid storm presents with normothermic hypoglycemia, and lactic acidosis, we believe it is necessary to consider a diagnosis of thyroid storm earlier, because this condition requires emergency treatment. Moreover, it is very important to apply standard principles in the treatment of atypical cases of thyroid storm.

It is well known that late-onset hypogonadism in males can cause a variety of symptoms, and the differential diagnosis is relatively difficult, including psychological disorders, stress, and mood disturbances. The level of serum cortisol can be measured to reflect a patient's level of stress. Salivary hormones facilitate the evaluation of physiological hormonal actions based on free hormone assay. ⋯ Salivary testosterone levels negatively correlate with age, regardless of the time of saliva collection (r=0.64, p<0.05). However, there is no relationship between salivary cortisol and age (r=0033, p>0.05). LC-MS/MS allows rapid, simultaneous, sensitive, and accurate quantification of testosterone and cortisol in saliva for the diagnosis late-onset hypogonadism or other hormone related disease.

The prevalence and titer of glutamic acid decarboxylase antibody (GADAb) in type 1 diabetes mellitus (T1DM) has been reported to be higher in patients with autoimmune thyroid diseases (AITD) than those without them. However, we have no data about the influence of GADAb on AITD. We therefore studied the clinical characteristics of Graves' disease (GD) with GADAb in order to clarify the influence of GADAb on GD. ⋯ Moreover, the rate of remission in the diabetic patients was no different from that of 21 control patients without diabetes followed for more than 7 years (5 in 14 vs 7 in 21). These data suggested that GADAb-positive patients are unlikely to go into remission with antithyroid agents. Therefore, definitive therapies might be preferable for the initial treatment of GADAb-positive patients.
