Recent basic and clinical studies demonstrate a major role for neural plasticity in the etiology and treatment of depression and stress-related illness. The neural plasticity is reflected both in the birth of new cell in the adult brain (neurogenesis) and the death of genetically healthy cells(apoptosis) in the response to the individual's interaction with the environment. The neural plasticity includes adaptations of intracellular signal transduction pathway and gene expression, as well as alterations in neuronal morphology and cell survival. At the cellular level, repeated stress causes shortening and debranching of dendrite in the CA3 region of hippocampus and suppress neurogenesis of dentate gyrus granule neurons. At the molecular level, both form of structural remodeling appear to be mediated by glucocorticoed hormone working in concert with glutamate and N-methyl-D-aspartate(NMDA) receptor, along with transmitters such as serotonin and GABA-benzodiazepine system. In addition, the decreased expression and reduced level of brain-derived neurotrophic factor(BDNF) could contribute the atrophy and decreased function of stress-vulnerable hippocampal neurons. It is also suggested that atrophy and death of neurons in the hippocampus, as well as prefrontal cortex and possibly other regions, could contribute to the pathophysiology of depression. Antidepressant treatment could oppose these adverse cellular effects, which may be regarded as a loss of neural plasticity, by blocking or reversing the atrophy of hippocampal neurons and by increasing cell survival and function via up-regulation of cyclic adenosine monophosphate response element-binding proteins(CREB) and BDNF. In this article, the molecular and cellular mechanisms that underlie stress, depression, and action of antidepressant are precisely discussed.

Quetiapine is an atypical antipsychotic drug with a benign side effect profile. However, recent studies have reported that thyroid dysfunction is associated with quetiapine treatment. The authors report a patient with DSM-IV bipolar I disorder who developed subclinical hypothyroidism during quetiapine treatment. The patient showed no significant clinical symptoms, but only abnormal thyroid function test findings including antithyroglobulin antibody. The abnormal thyroid function test findings were normalized after discontinuation of quetiapine. The subclinical hypothyroidism developed during quetiapine treatment may be associated with autoimmune process.

Femoral neck fracture has given marked attention to the orthopaedic surgeon due to complications, such as avascular necrosis of femoral head, non-union and degenerative arthritis, moveover common in older age group since early part of the 20th century. It is one of disabling and unsolved problems, so various techniques and implants were introduced and applied. Percutaneous Knowles pinning is one of simple, safe and reasonably effective method in treating femoral neck fracture, provided it is performed correctly. Nineteen cases of femoral neck fracture treated with precutaneous Knowles pinning at the Department of Orthopaedic Surgery, National Medical Center were analyzed and following result were obtained. l. Among the 19 cases, 13 cases were female and 6 cases were male, and high incidence was noted in older age group. 2. The amout of bleeding during operation was less than 100ml and the operative time was less than one and half hour under the local anesthesia in majority. 3. Good result was obtained in the group of operation less than 3 days after initial injury compared to more than 3 days group. 4. There was high complication rate in poor group than acceptable group according to Garden alignment index and we could predict the end result by aid of alignment index. 5. There was no cast immobilization in case of stable reduction, good fixation and good Rapport. 6. Bony union was established within 4.7 months in non-displaced fracture and 7.3 months in displaced fracture in average. 7. There were 1 case of avascular necrosis. 3 cases of non-union and 2 cases of degenerative osteoarthritis and poor results were correlated with Garden stage.

Neuroleptic malignant syndrome(NMS) is an uncommon but potentially fatal idiosyncratic reaction to neuroleptics, characterized by muscular rigidity, fever, autonomic dysfunction, and altered consciousness. The major theories to explain NMS is central dopaminergic blockade, but it is unclear. Risperidone is a new antipsychotic drug, a benzisoxazole derivative that blocks dopamine D2 receptor and serotonin type 2 receptor. The comparatively greater serotonin-blocking activity is believed to give risperidone the specific property of not causing any more extrapyramidal side effects than conventional antipsychotics at the optimal dose of 4-8mg/day. It is postulated that risperidone is unlikely to cause NMS. Here, we report a case of risperidone induced neuroleptic malignant syndrome.

In 1961, Salter had devised the innominate osteotomy in treating C.D.H, which has been one of the most popular methods in these days. 14 hips with 12 patients who have been admitted and received Salters innominate osteotomy in the department of orthopaedic surgery, National Medical Center, from Feb. 1974 to Dec. 1976, were evaluated as for the results. Clinical analysis and follow-up study were carried out in 14 hips with C.D.H. and the following results were obtained. The mean age of the cases was 34 months, and sex preponderance of female to male was 11: 1. The ratio of left to right was not significantly different. 2 cases of complication out of 12 cases was found; redislocation and subluxaiton respectively. The age of first detection of C.D.H., was surprisingly late around 18 months old. In addition, approximately 12 months has elapsed between the first detection of C.D.H. and the first consultation to doctor. Assesment of the result was carried out by Severine and Macays method respectively; Radiological evaluation was as followings: (Severine) Excellent: 4, Good: 8, Fair: 1, Poor: 1. Clineal evaluation was as followings: (Macay) Excellent: 4, Good: 7, Fair: 1, Poor; 1, Failure: 1.

Sixty amputees who had traumatic amputations due to industrial accidents were examined on their phantom limb and phantom pain phenomena and the following results were obtained. 1. Fifty-three (93%) of sixty amputees experienced phantom limb and twenty-four (40%) experienced phantom pain. The incidence of phantom pain in the lower limb amputation (59%) is greater than that of upper limb amputation (29%). 2. Amputees with asthenic body status gave higher incidence (56%) of phantom pain than those with muscular body status (20%). None of amputees with obese body status experienced phantom pain. 3. The sensation of strong current and cramping were most predominant sensations in the phantom pain. 4. Twenty-eight (93%) of thirty amputees had experienced painless phantom limb longer than four months. 5. Six (55%) of eleven upper limb amputees with phantom pain experienced pain sensation at the tips of fingers and nine (69%) of thirteen lower limb amputees with phantom pain experienced pain at the great toe. 6. Fifty-three (88%) of sixty amputees experienced telescoping of the lost limb and twenty-three (38%) of sixty amputees experienced jerking movement of the stump. 7. In fifty-four (90%) of sixty amputees, trigger zones triggering pain in the phantom limb were found in the healthy part of the body. 8. Twenty-two (40%) of fifty-five male amputees experienced burning sensation in the phantom limb associated with urination, defecation or ejaculation. 9. Cold temperature was predominant, aggrevating factor of the phantom pain. Fitting prosthesis and alcohol intake were predominant, relieving factor of the phantom pain.

PURPOSE: Leptin is a highly hydrophobic 16-kDa protein encoded by the ob gene which is expre- ssed in adipocytes and participates in the regulation of food intake and energy expenditure. The aims of the present study were to examine the comparison of leptin levels between type I diabetes mellitus (DM) patients who received exogenous insulin therapy and healthy children, and to find out correlating factors with leptin level in type I DM. METHODS: The study was conducted on 34 patients with type I DM and 29 healthy children. Body weight, height, leptin level and body fat percent were measured in both groups. The glycosylated hemoglobin value, C-peptide, insulin level and serum cholesterol were also measured in type I DM. RESULTS: There was no statistically significant difference in mean age, sex distribution and body mass index between the experimental groups, but body fat percent in type I DM was significantly lower than that of healthy children. The mean leptin levels in male (9.4+/-6.3ng/mL) and female (17.8+/-10.2ng/mL) type I DM were significantly higher than in male(6.3+/-5.7ng/mL) and female (10.2+/-0.9ng/mL) healthy children (male : P=0.045, female : P=0.005). Serum leptin levels were strongly correlated with the body fat percent (Pearson coefficient) (r=0.712). CONCLUSION: Serum leptin level in type I DM strongly correlated with the body fat percent. Despite lowered body fat percent in type I DM, the leptin level was significantly higher than values in healthy children. The mean leptin level in type I DM were significantly higher than value in healthy children, but body fat percent of type I DM was lower than value in healthy children who were adjusted for sex, age and body mass index.

In 1974, bipolar endoprosthesis was first introduced by Bateman & Giliberty. It has theoretical advantages including minimizing acetabular wear, possible reduction of incidence of stem loosening, lessening of dislocation and easy revision procedure. Various methods for the treatment of fracture of the femur neck have been developed & performed, but it is still called “the unsolved fracture” in certain situation. But the role of it as primary treatment of fracture of the femur neck continues to be controversial. Current clinical results encourage its continued use and expansion of indication. Authors reviewed and analysed 21 cases of bicentric endoprosthesis and 1 case of Giliberty endoprosthesis those have been operated at the Department of Orthopaedic Surgery, National Medical Center from 1981 to 1983. Following results were obtained, l. According to disorder distribution, 14 cases were neglected fracture of femur neck, 2 old fracture, 1 idiopathic femoral head necrosis and 2 avascular necrosis & 1 non-union complicated by femoral neck fracture. 2. Among 20 cases, 8 cases were operated within 1/2 1 month after injury and 6 cases within 1 3months 3. Harris lateral appmach was used in 16 cases (80%) and Modified Gibson approach in 4 cases (20%). There were no significant differences in morbidity during operation and postoperative complication. 4. We used femoral stems those head diameter was 22 and 32mm(Charnley & Miiller type) and head pieces those diameter was 48-51 mm in male and 44–48 mm in Ifemale. 5. 3 cases were stiff in inner bearing without acetabular erosion. 6. In 6 cases more than 2 years followup 1 degree CE angle of Wiberg was increased in 2 cases of youngage respectively without associated hip joint pain. 7. Although inclination of head piece was vertical in 8 cases, fracture and dislocation were not found. 8. The circumference of head piece and opposite femoral head was measured and compared. There were 12 cases (mean 12.6 mm) that of head piece larger than opposite femoral head and 3 cases smaller than opposite femoral head. 9. There was 4 cases of complication (3 patients) and still no reoperation and revision converted to T.H.R. 10. With regard to average 18 months of follow-up, 7 cases of 81–90 Harris hip-rating score, 6 of 91–100, 4 of 71–80 and 3 of 61–70.
