Any strenuous muscular exercise may trigger rhabdomyolysis. We report an episode of clinically manifested exertional rhabdomyolysis due to stationary cycling, commonly known as spinning. Reports of spinning-related rhabdomyolysis are rare in the English literature, and the current case appears to be the first such case reported in South Korea. A previously healthy 21-year-old Asian woman presented with severe thigh pain and reddish-brown urinary discoloration 24–48 hours after attending a spinning class at a local gymnasium. Paired with key laboratory findings, her symptoms were suggestive of rhabdomyolysis. She required hospital admission to sustain renal function through fluid resuscitation therapy and fluid balance monitoring. Because exertional rhabdomyolysis may occur in any unfit but otherwise healthy individual who indulges in stationary cycling, the potential health risks of this activity must be considered.

A Case of Hypothyroid Myopathy Found in Periodic Health Examination.
Young Gyu Cho, Hye Ryoung Song, Jae Heon Kang
J Korean Acad Fam Med 2008;29(8):612-616.   Published online August 10, 2008
Myalgia, muscle weakness, muscle cramping, muscular rigidity and elevated levels of serum creatinine kinase (CK) are very common in patients with hypothyroidism. However, these symptoms are not clinically serious in most cases and are not found in primary care. So far, 5 Cases with hypothyroid myopathy have been reported in the Korean literature. However, it is not reported that this case has been found in primary care or in periodic health examination. We report a case of hypothyroid myopathy that was presented with exercise-induced myalgia. This case was diagnosed as hypothyroid myopathy through abnormal thyroid function test and elevated levels of serum CK and myoglobin in periodic health examination. Muscle symptoms and laboratory abnormality were improved only with thyroid hormone replacement therapy. (J Korean Acad Fam Med 2008;29:612-616)

Predictors of High Peak Serum CK Levels in Doxylamine Intoxication.
Hea Jung Shin, Sung Kyung Lee, Kyoung Kon Kim, Kyung Hee Cho, Yong Joon Kang, Hee Chul Kang, Bang Bu Youn

Background
: Because doxylamine succinate (DS) is an over-the-counter medicine, it can be obtained easily and is frequently used in suicidal attempts. Patients usually recover without serious complications, but occasionally rhabdomyolysis and even death can occur in DS intoxication. In this study, the authors tried to find out the independent predictors of high peak serum CK levels, i.e. probable rhabdomyolysis in DS intoxication.

Methods : The medical records of 41 patients who visited a hospital for DS intoxication from January 1, 2002 to April 30, 2003, were reviewed retrospectively.

Results : In the group of DS only, initial occult blood of urine (P=0.003), initial WBC count (P=0.003) and confusion (P= 0.007) were the best predictors of the peak serum CK level (r2=0.724). In the group of DS with other drugs intoxication, initial creatinine level (P=0.003) and initial occult blood of urine (P=0.007) were the best predictors of the peak serum CK level (r2=0.784). In the cases of rhabdomyolysis patients, the time taken for the CK level to be increased over 1,000 IU/L was 1.9±0.6 days.

Conclusion : In DS only intoxication, occult blood in initial urine analysis, initial high WBC count and confusion can be thought of as useful clinical predictors for high peak serum CK level case. In DS with other drugs intoxication, initial creatinine level and initial occult blood of urine can be considered as the best predictors. More than 2 days will be needed for the observation of serious complications in DS intoxication.
