Backgrounds and Objectives: In the length-dependent axonal polyneuropathy like diabetic polyneuropathy (DPN), the distal part of the longer axons are affected earlier. In cases of minimal distal axonal changes, nerve conduction studies (NCS) are frequently normal. If sural nerve is affected in the early stage of DPN, supportive parameters to detect the early axonal degeneration may be helpful. We investigated whether the sural/ulnar SNAP amplitude ratio (SUAR) may be a more sensitive indicator than sural amplitude alone in the diagnosis of early diabetic polyneuropathy. Methods: We analyzed medical records and electrophysiological studies of 141 patients with DM and 30 healthy subjects. The patients with early stage of DPN were defined as those having symptoms of neuropathy and normal NCS findings among the patients with DM. We compared SUAR between 57 patients with early stage of DPN and 71 agematched control subjects. Results: Fifty seven patients had an average SUAR of 0.8, compared to that of 1.1 in the 71 normal controls. The SUAR of less than 0.9 was supplementary predictor of axonal polyneuropathy, with the best balance of sensitivity and specificity (70%). The SUAR did not vary significantly with age, height or duration of DM. Conclusions: We conclude that the SUAR is a useful electrodiagnostic indicator to detect early stage of DPN.

목적: 주관절 전지환 성형술의 최근 수술 결과와 합병증에 대하여 문헌을 토대로 기술하고자 한다. 대상 및 방법: 주관절 전치환술의 적응증은 다른 수술 방법으로 관절 기능의 회복이 불가능한 류마토이드 관절염, 외상후 관절염, 관절 강직, 종양 제거 후 상태, 그리고 고령의 원위 상완골 분쇄 골절 등이 있다. 합병증으로는 가장 심각한 합병증인 감염을 비롯하여 삽입물 이완, 삽입물 골절, 삽입물 주위 골절, 척골 신경병증, 이소성 골화, 상완 삼두근 손상, 탈구를 포함한 불안정, bushing의 마모 등이 있다. 결과 및 결론: 재치환술을 기준으로 한 주관절 치환술의 수명은 10년을 기준으로 85% 정도인 것으로 알려져 있다. 염증성 관절염이 가장 예후가 좋으며 외상후 관절염의 이완율이 비교적 높다. 합병증은 다른 관절의 치환술에 비해 많이 발생하는 경향이 있으며 특히 심부 감염은 3~5% 정도로 높은 편이다. 주관절 치환술은 재건술로 관절 기능을 회복할 가능성이 없는 활동력이 높지 않은 환자에 대해 신중하고 적절하게 시행한다면 만족스러운 기능 회복을 기대할 수 있다.

Objectives: This study examined the natural history of symptomatic patients who did or did not display abnormal results on nerve conduction studies (NCS). Methods: Forty hundred fifty adults were selected among a total of 578 residents who participated in the health examination in a rural Korean district. A symptom questionnaire and NCS were used to diagnose ulnar neuropathy at the elbow (UNE). There were 6.4% of the subjects with UNE, 5.1 % of the subjects showed symptoms without a NCS, and 84.2% of the subjects who were asymptomatic. One year later, 20 symptomatic limbs with an abnormality on the ulnar NCS and 22 symptomatic limbs without any abnormality in the ulnar NCS were enrolled in a follow-up study. The natural history of UNE was evaluated by examining the changes in the clinical and electrodiagnostic examinations. Results: The 1-year follow-up of the enrolled limbs found that for the symptomatic limbs with an abnormality on the NCS, the degree of severe of the clinical grade changed from 20% to 10%. In contrast, for the symptomatic limbs that were without any abnormality in the NCS, the change of the severe degree of the clinical grade was from 0% to 18.2%. Also, for the electrodiagnostic change, only symptomatic limbs without NCS abnormalities showed significant changes in motor latency, amplitude and conduction velocity at the 1-year follow-up. Conclusions: The 1-year follow-up study revealed symptomatic limbs that were without any abnormality on the ulnar NCS were more likely to progress than the symptomatic limbs with an abnormality on the ulnar NCS.

Purpose: Soft tissue chondroma is a rare benign tumor, found mainly on the palm and sole and grows slowly. Typically, mature hyaline cartilage is the dominant pathological feature. There are reports that assert soft tissue chondromas to be a cause of median nerve entrapment syndrome. However, this is the first case report showing soft tissue chondroma to be a cause of simultaneous median and ulnar neuropathy. Methods: A 62 year-old woman presented with chief complaints of numbness and hypoesthesia of her right palm for 4 to 5 years, and a palpable mass on her right palm that had been increasing in size slowly for 3 years. Physical examination revealed a firm, mobile, non-tender and about $3{\times}3\;cm^2$ sized mass in the center of the right palm. Electromyography showed entrapment neuropathy of the median and ulnar nerve. Ultrasonography showed an approximately $5.7\;cm^2$ mass below the flexor tendon of ring finger. Upon surgical excision, a $3{\times}3\;cm^2$ mass attached to the flexor digitorum profundus of ring finger and redness and hypertrophy of both the median and ulnar nerve were discovered. Mass excision was performed gently and the specimen was referred for histopathologic study. Mass excision resulted in median and ulnar nerve release. Results: The pathology report confirmed the mass to be a soft tissue chondroma with mature hyaline cartilage. The patient exhibited post-operative improvement of her symptoms and did not show any complications. Conclusion: This is the first case report showing soft tissue chondroma to be a cause of simultaneous median and ulnar neuropathy.
