대퇴 간부 골절에서 골수강 내 금속정 삽입술은 널리 사용되는 방법으로 교합나사의 삽입은 경피하에 삽입하며 특히 원위부는 가이드 없이 삽입하게 된다. 교합나사에 의한 혈관에 대한 합병증은 드물게 생기며 원위부 교합나사에 의해 발생한 지연성 가성 동맥류(delayed pseudoaneurysm)에 대해서는 아직 국내에서 보고된 바가 없었다. 이에 저자들은 지연성 가성 동맥류 2예를 경험하여 문헌고찰과 함께 보고하는 바이다. Interlocked intramedullary nailing is widely accepted for treatment of closed femoral shaft fractures. An interlocking screw is inserted percutaneously, and especially the distal screw is inserted without use of a guide. Vascular complications associated with an interlocking screw in intramedullary nailing are rare. No case of delayed pseudoaneurysm caused by a distal interlocking screw has yet been reported in Korea. We present two cases of delayed pseudoaneurysm caused by a distal interlocking screw several months after intramedullary nailing.

N/A Objective: We studied the efficacy of the power spectral and nonspectral analysis and its diurnal variations for the early detection of the diabetic autonomic neuropathy. Method: The spectral and nonspectral analysis of 24hour-Holter monitoring were done for both diabetic neuropathy patients and controls. We also made a comparative analysis of the diurnal variations between the patient and control groups by means of hourly power spectral analysis. Result: 1) The power spectral density of the diabetic neuropathy patients was below than that of the normal controls (P<0.05) (Table 2, Fig. 1). 2) The nonspectral analysis of the diabetic neuropathy patients was below than that of the normal controls except for the mean RR intervals (P<0.05) (Table 3). 3) Every hour-power spectral analysis showed a diurnal variation of day time (06:00 to 16:00) decrease in high frequency area of the normal controls. On the contrary, there was a disappearance of the diurnal variation in patient group. Conclusion: The power spectral and nonspectral analyses after 24hour-Holter monitoring and its diurnal variation in the diabetic patients are considered as good means of the early detection of autonomic neuropathy, but further study of its diagnostic value will be needed.

Everybody knows that toads are not eatable because of their toxins. But water toads are very similar to frogs morphologically, so fried water toads are eaten by some people on occasion. It has been studied that the granular glands of the toads secrete toxins known as digoxin-like immunoreactive substances (DIJS) such as bufogenins and bufotoxins. DLIS have cross-reactivity with microparticle enzyme immunoassay for the quantitative measurement of digoxin. We report a case of DLIS poisoning in 56-year-old male patient who showed vomiting, syncope, and marked bradyarrhythmia with block (heart rate down to 29 beats per minute) after ingestion of the fried water toads (Bufo stejnegeri Schmidt).
