Background To evaluate the diagnostic value of median sensory nerve conduction study in early phase of diabetic neuropathy. Methods The onset latency, duration, peak amplitude, and area of sensory nerve action potential (SNAP) of median nerve stimulated at wrist and elbow, respectively on 20 normal adults and 20 diabetic patients who revealed normal findings in conventional electrodiagnostic procedure were checked and compared. Results 1) The onset latency, peak amplitude, and area of SNAP stimulated at wrist of diabetic patients were significantly different than those of control group (p<0.05). 2) The conduction velocity, peak amplitude, and area of SNAP stimulated at elbow of diabetic patients were significantly different than those of control group (p<0.05). 3) The amplitude of SNAP stimulated at elbow on diabetic patient was most accurate parameter and next, the amplitude of median sensory nerve action potential stimulated at wrist. Conclusion The amplitude of median sensory nerve action potential stimulated at elbow are good quantitative indices of diabetic neuropathy who revealed normal findings in conventional electrodiagnostic procedure with positive neurologic symptom and physical examination.

Background:To provide useful information on the choice of adequate drugs in the treatment of urinary tract infection (UTI) in spinal cord injury patients. Materials and Methods:The subjects were 34 spinal cord injured patients who were registered in Busan Spinal Cord Disabled Person Society and 111 patients with spinal cord injury who were admitted in 4 university hospitals in Busan between January 2004 and December 2005. We collected the patient's urine in July 2006 and performed comprehensive chart reviews of these patients. We studied the incidence of UTI, commonly cultured organisms, antimicrobial sensitivities, voiding methods and follow-up. Results:The incidence of UTI was 48.3% of 145 patients. The most common causative organism of UTI was Escherichia coli (27.1%), followed by Pseudomonas aeruginosa (22.9%) and Klebsiella pneumoniae (8.3%). Antimicrobial sensitivities of imipenem, amikacin and ceftazidime to Escherichia coli were respectively 100%, 92.3%, 80.8%. The sensitivities of Pseudomonas to the same agents were 63.6%, 31.8 %, 45.5% respectively. Ciprofloxacin showed decreased sensitivities of 38.5%, 31.8% respectively for Escherichia coli and Pseudomonas aeruginosa. Conclusion:Our results implied decreasing susceptibility of ciprofloxacin, so it can be recommended to restrict the use of ciprofloxacin as a primary empirical antibiotic for UTI of spinal cord injured patients. Causative organisms of UTI are becoming more diverse. Also the incidence and antimicrobial sensitivities are changing as well. Therefore continuous observation with the appropriate treatment is needed. 목 적:척수손상 환자에서 요로감염의 흔한 원인균과 항생제 감수성을 조사하여 요로감염의 예방과 치료에 도움을 주고자 한다. 재료 및 방법:부산 척수장애 협회에 등록된 환자 중 이번 연구 참여에 동의한 34명에 대해 2006년 7월에 직접 방문하여 증상, 투약, 배뇨방법, 정기적인 외래 진료 유무 등에 관한 설문조사와 채뇨를 시행하였으며, 부산지역 4개 대학병원에서 2004년 1월부터 2005년 12월까지 요배양 및 항생제 감수성 검사를 시행한 적이 있는 척수손상 환자 111명의 의무 기록을 통해 배뇨방법, 정기적인 외래 진료 유무, 요로감염의 원인 균종 및 항생제 감수성을 조사하였다. 결 과:척수손상 환자의 요로감염 유병률은 48.3%로 나타났으며, 원인균주는 Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae 순으로 검출되었다. 그리고 항생제 감수성 검사에서 imipenem을 제외할 경우 Escherichia coli와 Klebsiella pneumoniae에서는 amikacin이, Pseudomonas aeruginosa에서는 ceftazidime이 가장 높게 분석되었고, ciprofloxacin에 대한 감수성은 감소하는 경향을 보였다. 결 론:요로감염에 대한 일차선택 약제로 감수성이 낮은 ciprofloxacin의 사용은 제한하는 것이 이번 연구의 결과와 부합할 것으로 판단되며, 요로감염의 원인균은 시간이 지날수록 다양해지고, 빈도 및 항생제 감수성 또한 변하므로 향후 지속적인 감시와 그에 따른 대처가 필요할 것으로 생각한다.

Objectives: To investigate the effects of Computerized Neuropsychologic Test (CNT) on cognitive function and daily life performance in subacute post-stroke patients with cognitive impairment. Methods: Korean Mini-Mentals State Examination (K-MMSE), Korean version of Modified Barthel Index (K-MBI) were investigated in 125 subacute post-stroke patients with cognitive impairment. We analyzed K-MMSE and K-MBI which were conducted 63 patients who had received CNT and 62 patient who had not received CNT from baseline to 8 weeks follow-up. In the experimental group, initial K-MMSE and K-MBI were conducted 13.3 ± 6.8 weeks after the onset of stroke and their age was 63.4 ± 13.3. In the control group, initial K-MMSE and K-MBI were conducted 13.2 ± 7.7 weeks after the onset of stroke and their age was 65.1 ± 11.6 Results: The 8 weeks follow-up total K-MMSE score and total K-MBI score of experimental group were significantly higher than control group ( P < 0.05). In K-MMSE subsection, orientation, judgement, recall, language & visual reconstruction were significantly higher in experimental group than control group ( P < 0.05). In K-MBI subsection, personal hygiene, bathing self, toilet, dressing, ambulation, chair/bed transfer were significantly higher in experimental group than control group ( P < 0.05). The change of total K-MMSE score of experimental group was significantly correlated with change of total K-MBI score ( P < 0.05), but control group was not ( P > 0.05). In K-MMSE subsection, change of orientation, registration, language and visual reconstruction were correlated with total K-MBI s core after CNT. Especially, the experimental group, total K-MBI score of the left hemisphere damage group was significantly higher than the right hemisphere damage group ( P < 0.05). Conclusions: This study shows that CNT is effective on subacute post-stroke patients with cognitive impairment. Improvement of cognitive function can expect a positive outcome on daily life performance, in particular, it can be expected to improve the prognosis of patients with stroke, the left hemisphere lesions.

경피적 전기신경자극 부위가 H-반사에 미치는 영향 및 실험 오차

Background: This study was designed to research the influence of H-reflex according to applying site of TENS and experimental bias. Materials and Methods: The H-reflexes were recorded in 40 normal healthy subjects by a standardized method of Braddom and Johnson. Two examiners measured H-reflex of each same subject. After TENS of 100Hz was applied for 15 minutes, and H-reflex were measured before and immediately after stimulation of TENS at popliteal fossa. H-reflex was measured to reveal change of each examiner bias by same time and method in next day. 30 healthy subject were measured before and after stimulate of TENS by same standardized method to investigate change of H-reflex according to applying site of TENS. Statistical analysis was done with paired t-test and student t-test of SPSS for window(version 10.0). Result: 1) H-latency showed no inter-examiner bias, but H-amplitude showed intra-examiner bias on repeated test. These results suggest that H-latency can be used as a experimental value, but not H-amplitude. 2) H-latency after TENS therapy on popliteal fossa, soleus muscle, and lumbar area increased can be used as a useful experimental value, but the value of H-amplitude is questionable. 2. The effects of H-reflex on TENS therapy, prolonged H-latency after TENS therapy regardless of stimulus site, may be due to the effect of conduction block on nerve system.

Objective: To determine the time period and factors inhibiting recovery of orthostatic hypotension during head up tilt with ischemic stroke patients.Method: Fourty two ischemic stroke patients with orthostatic hypotension were included. Blood pressure and heart rate were taken after resting in the supine position for 10 minutes and again after standing for one minute every week. Age, gender, body mass index, laboratory findings, diabetes mellitus, anti-hypertensive use, side of involved hemisphere and K-MBI were obtained.Results: The numbers of orthostatic hypotension patients were significantly decreased at 3rd week. Non recovering group until 3rd week were older in age and had higher plasma creatinine level. On the other hand, body mass index and K-MBI were lower than the group without orthostatic hypotention. Multivariate analysis revealed that age, body mass index, anti-hypertensive medication were independently associated factors for resistant orthostatic hypotension during head up tilt.Conclusion: For 7 weeks, especially at 3rd week, the numbers of orthostatic hypotension patients significantly decreased. Age, BMI, and antihypertensive medication were inhibitiing factors for recovery of orthostatic hypotension.

Objective: To identify the risk factors for secondary lymphedema after breast cancer surgery. Lymphedema, a sequelae of breast cancer therapy, changes functional abilities and may affect a patient's psychosocial adjustment and overall quality of life. It is generally underreported and undertreated. Method: Six hundred two patients who had undergone breast cancer surgery between January 2000 and December 2005 were examined. The circumferences of the upper extremities were measured and lymphedema was defined as difference of greater than 2cm between the affected and normal arms. The effects of age, body mass index, diabetes, hypertension, side of tumor, sugery method, radiotherapy, chemotherapy, TNM stage, involvement of axillary lymph nodes, menopausal state and laboratory findings on the development lymphedema were investigated and analyzed by t-test, chi-square test and multiple logistic regression analysis. Results: 121 out of 602 patients had lymphedema. Those patients with lymphedema had a higher body mass index. Univariate analysis indicated an increased occurrence of lymphedema due to those with body mass index, radiotherapy, T2 stage, N3 stage and axillary lymph node invasion. Multivariate analysis revealed that body mass index and radiotherapy were independently associated factors for lymphedema after breast cancer surgery. Conclusion: The patients who had radiotherapy or BMI greater than 25 must be considered as potential candidates to have lymphedema after breast cancer surgery. Therefore, these patients should be informed during the follow-up period about this morbidity, the preventive measure, and the treatment.

정호중,조태준,최인호,정진엽,유원준,박문석,배정연 대한정형외과학회 2010 Clinics in Orthopedic Surgery Vol.2 No.2

Background: The hemiepiphyseal stapling has both positive and negative effects on effective leg length. The purpose of this study was to analyze change in effective leg length after angular correction by hemiepiphyseal stapling, and to validate in clinical cases. Methods: Mathematical analysis of a hemiepiphyseal stapling model was conducted. The induced formula was validated in 6 cases fulfilling the assumptions of the model. Anatomical parameters involved in this formula were measured in additional 21 cases undergoing hemiepiphyseal stapling or hemiepiphysiodesis. Results: Effective leg length increased or decreased according to three parameters in this model: 1) limb length distal to the operated physis (L), 2) width of the operated physis (d), and 3) the amount of angular deformity to be corrected (θ). Actual change in effective leg length of 6 cases similar to this model coincided with the predicted change at least in its direction. L/d ratio was 4.82 ± 0.51. Conclusions: Considering the narrow range of the L/d ratio, hemiepiphyseal stapling is likely to decrease effective leg length if the amount of angular correction is less than 10°, whereas to increase it if the amount of angular correction is larger than 16°. This should be taken into consideration when selecting the surgical method for angular deformity correction in skeletally immature patients
