Total Hip Replacement is well documented and widely used procedure for painful arthritic hip in past two decades and each year still seems to be increased in numher of total hip replacement. And recently, there is a few reports of follow-up study on total hip arthroplasty in our country. The aim of this study was to present the clinical material which was performed on 27 hips of 21 patients who were treated at Dept. of Orthopedic Surgery. College of Medicine, Chungnam university from jan, 1979 to Jan. 1982. The longest follow up was 4 years, shortest was 8 months, average time was 2 years and 8months The results were obtained as follow; 1. The age incidence ranged from 26 to 69 years old, and average were 47 years old. 2. There were 17 males (81%) and 4 females (19%). 3, The causes of hip disease were mostly avascular necrosis of the femoral head (67%). 4, The most commonly used prosthesis were Muller type with trochanteric ostcotomy approaches. 5. Several complications were found: perforation of acetabulum with bone cenent in pelvis, postperative pneumonia wire breakage and painful bursitis around the trochanteric area which was on osteotomy sites. 6. Postoperative functional evaluation was evaluated by method of d'Aubigne and Postel, and improved from 10.0 scores to 15.8 scores. Relief of the pain is the most effect of the total hip replacement in this study, But case are not enough to more detail evaluation, especially, the problem of loosening of stem, acetabular cup wearing and heterotopic bone formation after total hip replacement.

Klebsiella pneumoniae is an unusual cause of brain abscess. Among the few cases of Klebsiella pneumoniae brain abscess that have been reported, most were associated with another underlying primary focus of infection. Endogenous endophthalmitis caused by Klebsiella pneumoniae is an infrequent but often devastating septic metastatic infection. We report a rare case of Klebsiella pneumoniae brain abscess and endophthalmitis after acute epiglottitis.

Reconstruction of calvarial bone defects from congenital anomaly or from bone loss due to traumatic or neoplastic processes remains a significant problem in craniofacial surgery and neurosurgery. To facilitate bone regeneration, there have been many trials such as autologous bone graft or allograft, and the addition of demineralized bone matrix and matrix-derived growth factor. Guided bone regeneration is one of the methods to accelerate bone healing for calvarial bone defects especially in children. Pericranium is one of the most usable structure in bone regeneration. It protects the dura and sinus, and provides mechanical connection between bone fragments. It supplies blood to bone cortex and osteoprogenitor cells and enhances bone regeneration. For maximal effect of pericranium in bone regeneration, authors used pericranium as a flap for covering calvarial defects in surgeries of 11 craniosynostosis patients and achieved satisfactory results: The bone regeneration of original cranial defect in one year after operation was 74.6%(+/-8.5%). This pericranial flap would be made more effectively by individual dissection after subgaleal dissection rather than subperiosteal dissection. In this article, we reviewed the role of pericranium and reported its usefulness as a flap in surgery of craniosynostosis to maximize bone regeneration.

BCG (Bacillus Calmette-Guerin), which produces resistance to tuberculosis infection, is a vaccine containing live, attenuated Mycobacterium bovis. It induces specific and nonspecific dermatologic complications. The specific reactions include scrofuloderma-like, lupus vulgaris-like, lichen nitidus-like, lymphadenitis and tuberculid. We report a case of papular tuberculid, which was presented as 3-5mm sized erythematous papules on the extremities and face, and BCGitis had developed around the vaccination site after BCG vaccination. Histopathologic examination of the papule and lymph node showed granuloma, consisting of epithelioid cells and lymphocytes.

OBJECTIVES: An ecofriendly alternative to chemical pesticides is bio-pesticides, which are derived from natural sources. The interest in bio-pesticides is based on the disadvantages associated with chemical pesticides. METHODS: We conducted acute toxicity assessments of camphor, a major component of bio-pesticides, by using Daphnia magna (D. magna) as well as assessed the morphological abnormalities that occurred in Danio rerio (D. rerio) embryos. RESULTS: The median effective concentration of camphor on D. magna after 48 hours was 395.0 muM, and the median lethal concentration on D. rerio embryos after 96 hours was 838.6 muM. The no observed effect concentration and predicted no effect concentration of camphor on D. magna, which was more sensitive than D. rerio, were calculated as 55.2 muM and 3.95 muM, respectively. Morphological abnormalities in D. rerio embryos exposed to camphor increased over time. Coagulation, delayed hatching, yolk sac edema, pericardial edema, and pigmentation of embryos mainly appeared between 24 and 48 hours. Further, symptoms of scoliosis and head edema occurred after 72 hours. In addition, bent tails, ocular defects and collapsed symptoms of fertilized embryonic tissue were observed after 96 hours. CONCLUSIONS: The camphor toxicity results suggest that continuous observations on the ecosystem are necessary to monitor toxicity in areas where biological pesticides containing camphor are sprayed.

Hyperreflexic bladder is a disease manifested in patients with spinal cord lesions above the sacral segment. The treatments for hyperreflexic bladder are medical therapy, interruption of innervation, argumentation cystoplasty, etc. We treated four hyperreflexic bladder patients with 12% a phenol injection into the subarachnoid space for sacral nerve block. Before treatment the average bladder capacity was about 100 ml, and there was one case of autonomic dysreflexia. After the subarachnoid block the average bladder capacity increased above 300 ml and maximal intravesical pressure decreased below 30cmH2O, autonomic dysreflexia disappeared in one patient. The decreased bladder compliance after nerve block was managed by repetitive bladder overdistention. We suggest that subarachnoid block is easier and more effective than sacral nerve block individually, and is a treatment for hyperreflexic bladder refractory to medical therapy.

BACKGROUND: Studies on herpes zoster have been extensively reported in Korea. However, few reports have dealt with herpes zoster in children and adolescents. OBJECTIVE: The purpose of this study was to investigate the epidemiological features and clinical characteristics of herpes zoster in children and adolescents. METHODS: During a 10-year period (2005~2014), 95 herpes zoster patients, aged 18 years and younger, were evaluated in regard to the annual, monthly, and seasonal incidences; the age distribution; and the gender ratio. The children and adolescents with herpes zoster were further assessed on the accompanying symptoms, dermatomal distribution, associated diseases, treatments, and complications. RESULTS: Among all the patients with herpes zoster, 2.41% were children and adolescents. The highest incidence was in summer (35.8%). The age group of 10 to 14 years had the highest incidence (40.0%). The male to female ratio was 1.4:1. The common accompanying symptoms were pain (77.9%) and pruritus (22.1%). The most common dermatomal distribution was the thoracic dermatome (50.5%), followed by the cervical (21.1%), the trigeminal (16.8%), the lumbar (7.4%) and the sacral (4.2%) dermatomes. Associated diseases including atopic dermatitis, bronchial asthma, allergic rhinitis, chronic sinusitis, and epilepsy were observed in 23.2%. There was no case with immunosuppression. The most common complication was secondary bacterial infection (5.2%), followed by herpes zoster ophthalmicus or herpes zoster generalisatus (4.2%), Ramsay Hunt syndrome (2.1%), meningitis and recurrent herpes zoster (1.1%). No patient developed postherpetic neuralgia. CONCLUSION: Herpes zoster is rare and relatively mild in healthy immunocompetent children and adolescents. Pruritus was observed in some pediatric patients, but there was no occurrence of postherpetic neuralgia.

PURPOSE: Medical students' values figure prominently in their choice of medical specialty; yet, little research has been performed on this topic. The purpose of this study was to analyze the differences in values according to medical students' individual characteristics (medical educational system, gender, and grade) and preferred medical specialty. METHODS: A total of 905 medical students participated in the study; 426 were graduate-entry medical students (GEMS), and 479 were undergraduate medical students (UMS). Further, 561 were male and 316 were female; 356 were in year 1, 219 were in year 2, 230 were in year 3, and 100 were in year 4. Students completed the Physician Values in Practice Scale (PVIPS). The PVIPS comprises six dimensions: autonomy, management, prestige, service, lifestyle, and scholarly pursuits. The data were analyzed by t-test and analysis of variance. RESULTS: GEMS had higher scores for service, management, and scholarly pursuits than UMS. Males had higher scores for prestige, lifestyle, and management, whereas female scored higher on service and scholarly pursuits. Higher grade was associated with increased scores for prestige, lifestyle, and management. The differences in lifestyle and scholarly pursuits were significant between preferred specialties. Students in support specialties scored significantly higher on lifestyle. With regard to scholarly pursuits, basic science specialties scored significantly higher than other specialties. CONCLUSION: There were significant differences in PVIPS according to individual characteristics and preferred medical specialty. This result could be useful in developing a medical specialty choice program for medical students.
