A Case of Hyperglycemic Hyperosmolar Syndrome in a Patient with Central Diabetes Insipidus and Type 2 Diabetes Mellitus / 대한내과학회지

Diabetes insipidus is a disorder caused by complete or partial deficiency or unresponsiveness to antidiuretic hormone. Both diabetes mellitus and diabetes insipidus are well-known causes of polyuria and polydipsia. Although Wolfram Syndrome, which is characterized by the concurrence of diabetes mellitus and diabetes insipidus along with optic atrophy and ataxia, is frequently reported, the concurrence of diabetes insipidus and type 2 diabetes mellitus without optic atrophy and deafness is rare. We report a 31-year-old woman presenting with hyperglycemic hyperosmolar syndrome caused by type 2 diabetes mellitus complicated with concurrent central diabetes insipidus.

A Case of Acute Emphysematous Pancreatitis / 대한내과학회지

Emphysematous infections of the abdomen are potentially life-threatening conditions that require aggressive medical and surgical management. Emphysematous pancreatitis is an uncommon disease that presents as acute pancreatitis with intra-parenchymal gas at the time of diagnosis. Traditionally, emphysematous pancreatitis is an indication for surgical intervention. However, a few cases of emphysematous pancreatitis, managed successfully without surgical debridement have been reported. We present a case of emphysematous pancreatitis managed medically without surgical debridement in a 56-year-old male.

Gender Differences in Susceptibility to Smoking among Patients with Lung Cancer

BACKGROUND/AIMS: To determine whether female smokers are more or less susceptible to the detrimental pulmonary-function effects of smoking when compared to male smokers among patients with lung cancer. METHODS: Pack-years and pulmonary function indices were compared between 1,594 men and women with lung cancer ifferences in individual susceptibility to smoking were estimated using a susceptibility index formula. RESULTS: Of the patients, 959 (92.8%) men and 74 (7.2%) women were current smokers. Common histological types of lung cancer were squamous cell carcinoma, adenocarcinoma, and small cell carcinoma, among others. Women had a lower number of pack-years, forced expiratory volume in 1 second (FEV1, liters), forced vital capacity (FVC, liters), and total lung capacity (TLC, liters) compared to those of men (25.0 +/- 19.2 vs. 42.9 +/- 21.7 for pack-years; 1.4 +/- 0.5 vs. 2.0 +/- 0.6 for FEV1; 3.0 +/- 0.7 vs. 2.0 +/- 0.6 for FVC; 4.5 +/- 0.8 vs. 5.7 +/- 1.0 for TLC; all p < 0.001). The susceptibility index for women was significantly higher compared to that of men (1.1 +/- 4.1 vs. 0.7 +/- 1.1; p = 0.001). A significant inverse association was shown between the susceptibility index and TLC and FVC (r = -0.200 for TLC, -0.273 for FVC; all p < 0.001). CONCLUSIONS: The results suggest that the detrimental effects of smoking on pulmonary function are greater in women, as compared to those in men, among patients with lung cancer.
