CHIEF will be among the largest Eastern Asian armed forces cohort, in which physical status was strictly evaluated to follow up the hospitalization events for severe illness.

Objective: To characterize the course of therapy in a large cohort of Chinese patients with thyrotoxic periodic paralysis (TPP), a reversible electrolyte emergency fraught with therapeutic challenges. Design and methods: In this prospective interventional study, 78 patients with TPP (75 males and three females with an age range of 16-48 years) were consecutively enrolled over a 6-year period. Intravenous KCl at a rate of 10 mmol/h was administered until muscle strength recovered. Serum potassium (K C ) and phosphorus concentrations were measured hourly during the paralytic attack and for 6 h after recovery. Results: The serum potassium (K C ) on attack was 2.1G0.2 mmol/l. The dose of KCl administered to restore muscle strength was 63G32 mmol, and peak serum K C concentration after recovery was 5.3G0.5 mmol/l. A paradoxical fall in serum K C concentration O0.1 mmol/l difference between presentation and treatment nadir was observed in approximately one-fourth of TPP patients (nZ20). These patients had significantly higher serum-free thyroxine concentration, systolic blood pressure, and heart rate on presentation, as well as serum phosphate concentration on recovery. They not only needed much more KCl supplementation (104G34 vs 48G19 mmol, P!0.001), but also had significantly more severe rebound hyperkalemia (5.8G0.5 vs 5.1G0.4 mmol/l, P!0.001) on recovery than those who did not have paradoxical hypokalemia. There was a positive correlation between the dose of KCl administered and the difference between peak and nadir serum K C (D K C ) (rZ0.68, P!0.001). Conclusions: TPP patients who do not develop paradoxical hypokalemia need a smaller KCl dose to achieve recovery, whereas those who develop paradoxical hypokalemia have more severe hyperthyroidism and hyperadrenergic activity and may require blockage of intracellular K C shift to prevent rebound hyperkalemia.

Diabetes is a serious global health problem. Large-scale genome-wide association studies identified loci for type 2 diabetes mellitus (T2DM), including adiponectin (ADIPOQ) gene and transcription factor 7-like 2 (TCF7L2), but few studies clarified the effect of genetic polymorphisms of ADIPOQ and TCF7L2 on risk of T2DM. We attempted to elucidate association between T2DM and polymorphic variations of both in Taiwan's Chinese Han population, with our retrospective case-control study genotyping single nucleotide polymorphisms (SNPs) in ADIPOQ and TCF7L2 genes both in 149 T2DM patients and in 139 healthy controls from Taiwan. Statistical analysis gauged association of these polymorphisms with risk of T2DM to show ADIPOQ rs1501299 polymorphism variations strongly correlated with T2DM risk (P = 0.042), with rs2241766 polymorphism being not associated with T2DM (P = 0.967). However, both polymorphisms rs7903146 and rs12255372 of TCF7L2 were rarely detected in Taiwanese people. This study avers that ADIPOQ rs1501299 polymorphism contributes to risk of T2DM in the Taiwanese population.

Hypokalemic paralysis is a rare presentation of Fanconi syndrome (FS) caused by Sjögren Syndrome (SS). We describe a 39-year-old man who manifested flaccid paralysis of 4 limbs. Laboratory investigations showed profound hypokalemia (1.6 mmol/L) with renal K wasting, hyperchloremic metabolic acidosis with positive urine anion gap, hypophosphatemia with hyperphosphaturia, hypouricemia with hyperuricosuria, normoglycemic glycosuria, and abnormal serum creatinine concentration 2.2 mg/dL. A thorough survey for the cause of FS revealed that he had xerophthalmia and xerostomia accompanied by high anti-Ro antibody, positive Schirmer test, and delayed saliva excretion on sialoscintigraphy, confirming the diagnosis of SS. Potassium citrate, active vitamin D3, and high phosphate diet for his FS coupled with mycophenolate mofetil for SS resolved clinical symptoms and ameliorated renal function. Early recognition of HP due to the underlying SS-related FS with prompt therapy not only could terminate potentially life-threatening hypokalemia, but also improve renal outcome.

1. Military recruits frequently succumb to exertional heat stroke during intensive training. Since widespread endothelial injury is often associated with exertional heat stroke, the relationship between changes in three circulating endothelial cell markers (angiotensin-converting enzyme, von Willebrand factor antigen and thrombomodulin) and exertional heat stroke was studied. 2. Twelve recruits who had succumbed to exertional heat stroke during basic physical training (5000 m running) were included in the study. Another 10 age-matched healthy subjects who had gone through the same physical training regimen were selected as controls. 3. Blood was withdrawn on admission and on discharge for analyses of angiotensin-converting enzyme, von Willebrand factor antigen and thrombomodulin. Other physiological parameters and biochemical analyses reflecting renal and liver functions were also recorded. 4. Our results indicated that these subjects with exertional heat stroke exhibited impaired liver function as revealed by the significant elevation of both serum glutamic oxaloacetic transaminase (P < 0.05) and serum glutamic pyruvic transaminase (P < 0.05) as compared with normal healthy control subjects. Unfortunately, these values remained mostly somewhat elevated on discharge, although serum glutamic oxaloacetic transaminase was reduced dramatically. Indices of kidney functions, including creatinine clearance and uric acid and phosphorus secretion, were not significantly different from those observed in healthy controls. 5. Circulating angiotensin-converting enzyme activities in exertional heat stroke patients on admission were significantly lower than in normal subjects (10.68 +/- 2.15 versus 21.21 +/- 3.18 nmol hippuric acid min-1 ml-1, P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
