Bilateral trapped lung with concomitant Wermer's syndrome and cutis laxa.

We report a rare occurrence of trapped lung associated with Wermer's syndrome and cutis laxa. A 25-year-old man with bilateral trapped lung presented with respiratory distress. Additional investigation revealed adenoma of the parathyroid and hypophysis, a neuroendocrine abdominal tumor, and cutis laxa. Successful treatment of the respiratory symptoms was achieved through a median sternotomy with bilateral decortication, and excision of the bilateral fibrous pleural bands and bullae on the right upper lobe. Octreotide therapy was initiated and a percutaneous ultrasound-guided alcohol injection to the parathyroid adenoma was done. The patient has gynecomastia, acromegaly, and kyphoscoliosis. The patient remains well at 19 months after treatment.

Subclinical hypothyroidism is characterized by increased QT interval dispersion among women.

OBJECTIVE: Increased QT interval dispersion (QTd) is an electrocardiographic parameter shown to be associated with malignant ventricular arrhythmias and sudden death, and QT dispersion corrected for heart rate (QTc) has emerged as a potentially important predictor of cardiac death. Increased QTd has been detected to be directly related to thyroid-stimulating hormone (TSH) levels in overt hypothyroidism, however not much is known about subclinical hypothyroidism (SH). This study was conducted to investigate the QTc in SH and determine the changes following normalization of TSH levels with L-thyroxine. SUBJECTS AND METHODS: Fifty-eight women with naive SH due to Hashimoto's thyroiditis, mean age 39.37 +/- 10.43 years, and 54 age-, sex- and weight-matched controls with normal TSH were included after exclusion of any factor that might interfere with cardiac conductibility. Electrocardiographic measurements were performed with a magnifier and Bazett's formula was used to calculate QTc. The patients were separated into two groups regarding basal TSH levels (subgroup A: 5 > TSH > 10 mIU/l, n = 36; subgroup B: TSH > 10 mIU/l, n = 22). L-Thyroxine 1-2 microg/kg/day was administered to subgroup B. RESULTS: Mean QTc interval of the study group was significantly longer than that of the control group (100 +/- 30 vs. 76 +/- 30 ms, p = 0.000). It was also longer in subgroup A (5 > TSH > 10 mIU/l, n = 36) and subgroup B (p = 0.001, p = 0.000, respectively). In subgroup B, following normalization of serum TSH, mean post-treatment QTc measurement was similar to that of the control group (75 +/- 40 vs. 76 +/- 30 ms, p > 0.05). CONCLUSION: We detected prolonged QTc among SH cases. Prolongation remained significant for the whole group as well as the two subgroups. The differences in QTc were corrected when TSH levels of >10 mIU/l returned to normal.
