The thoracic and lumbar spine fractures were usually combined with neurological deficit. But the prognostic factors in degree of neurological damage and process of the recovery are controversial. The purpose of this study is to evaluate the factors affected neurological injury and the recovery. The 31 cases who had been performed surgical interventions due to traumatic thoracic or lumbar spine fractures with the neurological deficits were studied according to the radiographic findings of the spinal columns and neurological changes of the injured cord and/or the roots. The duration of mean follow-up was 32.6 months, and all cases were evaluated by motor index score and Frankel grade. Total cases were divided into complete paralytic (N=8) and partial paralytic(N=23) group. In incomplete paraplegia group, the neurological recovery rate was better than complete group(P < 0.001) and neurological recovery period was shorter than complete group (P=0.005). The neurologic deficits according to the Frankel grade were higher in Chance fracture, flexion-distraction and translation (complete paraplegia: 4/7 cases, 57.1%) than unstable bursting fracture (complete paraplegia: 4/24 cases, 16.7%)(P=0.031). The recovery rate of Chance fracture, flexion-distraction and translation were worse than unstable bursting fracture (0.001). The fracture which occurred in T5-11 showed higher incidence of complete paraplegia(75%) compared with that of the T12-L1(30.8%) & L2-4(7.1%)(p=0.021). The neurological recovery in motor index score in L2-4 was higher than T5-11 or T12-L1(P=0.0017). There was no correlation in kyphotic deformity and anterior body height loss between complete and incomplete paraplegia groups. But the A-P diameter of compromised neural canal showed significant difference between complete and incomplete paraplegia group(P=0.027)

BACKGROUND: Diagnosis of paucibacillary leprosy is difficult owing to lack of sensitive diagnostic tools. Recently, several investigators have studied the use of polymerase chain reaction(PCR) to detect Mycobacterium leprae. Using nested-PCR the sensitivity and specificity of DNA amplification is considerably improved. OBJECTIVE: The purpose of investigation is to assess the efficacy to nested-PCR which is applied to formalin-fixed, paraffin-embedded biopsies material of patients with leprosy. METHODS: Biopsy samples were taken from patients with lepromatous(11 patients) and tuberculoid (10 patients) leprosy, fixed in formalin, and embedded in paraffin. The DNA from samples was extracted and amplified through 25 cycles by using the outside pairs of primer(L1 and L2). The second amplification was allowed to proceed through 15 cycles using inside pairs of primer(L3 and L4). RESULTS: All twenty one samples showed 347-base-pair products. To confirm that the 347-bp product did correspond to the expected portion of the M. leprae groEL gene, the amplified product was digested with Pst I. Pst I digestion yielded 254-and 93-bp fragments, as predicted from the sequence of the M. leprae gene. The sensitivity was that a single organism was identified by nested-PCR. CONCLUSION: The nested-PCR is sensitive, specific, and simple diagnostic tool for leprosy.

Castleman disease is a relatively rare disease of differential diagnostic interest in patients with lymphadenophathy. The etiology and pathogenesis of the Castleman disease are still not elucidated and the MRI findings of disease has not yet been reported. Two patients with Castleman disease studied by MRI are presented: one case presented with a localized anterior mediastinal mass and the other case, with a neck mass. The lesions were characterized by relatively high signal intensities on both T1 and T2 weighted images in both cases, and significant degree of enhancement was seen in the cervical Castleman disease.

Inadvertent application of ionizing radiation, a valuable tool in diagnostic radiology and radiotherapy, results in injury and death of adjacent normal cells, inducing gene mutations or even producing latent cancers. Captopril, an angiotensin I converting enzyme (ACE) inhibitor, has been reported to prevent the structural and functional changes in variable organs, such as lung and kidney, from radiation injury in different experimental animal models. An experiment was carried out to elucidate the radiation-induced histomorphologic changes of small intestine, especially jejunum, and to determine whether captopril can reduce or prevent the radiation-induced injuries in jejunum. Twenty-six healthy Sprague-Dawley rats were used. Experimental group (n=24) was divided into two large groups: the first one (n=16) was treated with two different single dose (9 Gy, 17 Gy) irradiation only and was sacrificed at 12 hours and at 8 weeks following irradiation; the second one (n=8) received captopril 500 mg/l per oral continuously after same doses of irradiation and was sacrificed at 8 weeks. The control group (n=2) was maintained on a stock diet in a same period of experimental group and sacrificed coincidentally. On light and electron microscopy, the 9 Gy and 17 Gy 12 hours groups revealed frequent apoptosis and necrosis but extremely decreased mitotic figures of the crypt cells. However, the 9 Gy and 17 Gy 8 weeks groups and the combined irradiation with captopril groups showed extremely reduced apoptosis and necrosis with increased mitotic figures. There was good correlation between experimental groups in apoptotic count and mitotic count (p<0.05). In the 9 Gy and 17 Gy 12 hours groups, the mucosal surface was focally or diffusely fragmented and the villi were slightly to moderately distorted. Collagen deposition was very mild and confined to the lower portion of the lamina propria. The 9 Gy and 17 Gy 8 weeks groups showed more severe mucosal surface fragmentation even with foci of erosion, short and distorted villi, and more intense collagen deposition. In contrast, the combined irradiation with captopril groups revealed complete regeneration of the mucosal surface epithelium and absent collagen deposition. These findings suggest that the acute radiation injuries to small intestine occur principally in the mucosal crypt cells. Captopril, the ACE inhibitor, might provide a useful intervention in the radiation injuries of intestinal mucosa.

In order to investigate the factors influencing QOL and life satisfaction of the physically disabled, the author interviewed, by using structuralized questionnaire, 440 individuals among the physically disabled who were participated in Health Examination from April to July, 1997. The questionnaire consisted of the general characteristics(sex, age, marital status, family number, etc), the Reintegration to Normal Living Index(RNLI) to assess QOL, and the single item of five-likert scale to evaluate life satisfaction. The means of RNLI were 16.2+/-4.8 in total score, 12.2+/-3.4 in daily functioning and 4.0+/-2.1 in perception of self. The respondents were less reintegrated toward social activities and relationships than impairments or disabilities. While the satisfied group was 47.3%, the dissatisfied group was 52.7%. As the results of multiple regression and logistic regression analysis, the significant predictors of QOL were age, education, job, grade of disability and subjective health status. The life satisfaction were related to economic status, job and subjective health status. To improve QOL and life satisfaction of the physically disabled, it is important that we improve their basic socioeconomic status by getting a job through rehabilitation education and induce them to have positive self-assessment by extending the opportunity of social participation.
