Fractures of the capitellum humeri are rare and the recommendations for treatment vary. It can involve a significant portion of the articular surface, rendering the elbow joint unstable. In this situation, it is desirable to reduce and internally fix the capitellar fragment, because this restores the articular surface and augments joint stability. We experienced two cases of capitellar fractures which one case was spontaneously anatomical reduced and the other case was treated by open reduction. In one case the capitellar fragment was spontaneous reduced to a stable position although it was noticed radiographically as an unstable displaced fracture preoperatively. The other case was treated by open reduction and internal fixation with 3.5mm, small, AO, cannulated screw and K-wire. Both cases are reported here with references.

From July 1997, Authors have reconstructed the posterior cruciate ligament(PCL) deficient knees with two graft tendons; an autogenous bone-patellar tendon-bone (BPTB) and a semitendinosus tendon. At Femoral side, the two graft tendons were fixed through the two tunnels which were made at the site of foot print of PCL. The original site of anterolateral bundle of the PCL was reconstructe(I with the autogenous BPTB and the original site of posteromedial bundle with the semitendinosus tendon. At tibial side, the two graft tendons were fixed by modified inlay technique; the BPTB was fixed with a cancellous screw and the semitendinosus tendon with staples. Seven cases were followed up more than six months and authors evaluated the results with the KT-1000TM arthrometer and the posterior stress radiographs by Telos stress dcvice and compared the resu]t of injured knee with the uninjured side of each patient. The results of manual maximal displacement test with arthrometer were less than 4 mm in six patients and 8 rnm in one patient at last follow up. The average distance of posterior displacement on stress radiographs was 10.3 mm preoperatively and 2.7 mm at final follow up period. Six of the seven patients had a good stability on posterior stress radiographs compared with the uninjured side. One patient had posterior knee insta- bility on stress radiographs due to loosening of the grafted tendon and retightening of the grafted tendon was performed through the posterior approach to the proximal tibia. The original idea of femoral dual tunnel method in PCL reconstructiori is to reconstruct the PCL more anatomically and the modified tibial inlay technique can solve the problern of graft tendon abrasion at the posterior opening of the tibial tunnel in transtibial tunnel method and retightening of the loose grafted tendon is simple than the other methods of PCL reconstruction. Authors expect that this combined femoral dual tun- nel and modified tibial inlay method may improve the quality of the outcome of the arthroscopic PCL reconstruction.

OBJECTIVES: Electroconvulsive therapy (ECT) is the important treatment method which has a good effect on refractory depression, schizophrenia at acute stage, patients with suicidal ideation. Although ECT results in better effects and less adverse effects in acute stage of illnesses as compared with pharmacotherapy, clinical implications are decreasing. Thus, authors surveyed a view of Korean psychiatrists about ECT to find whether there are prejudices and/or misconceptions for ECT. METHODS: Authors made survey questionaire for the attitudes of ECT, based on the APA task force 14, a clinical study in Korea, Hermann et al's report, and questioned Korean psychiatrists on their opinions for ECT through the internet E-mail, who are the members of Korean Neuropsychiatric Association (KNPA) serving in hospitals with psychiatric inpatient units. RESULTS: 122 psychiatrists answered to survey questionnaire. 89.4% have positive attitude about ECT. They thought that ECT has relatively safe and potent therapeutic effects, and less adverse effects. The rate of psychiatrists who have been no experience to perform ECT was 13.9% (n=16). Interestingly all of them had been trained serve in university hospitals now. The rate of psychiatrists who had experienced practicing ECT past but, not experienced within 2 years recently was 48.7% (n=56). While psychiatrists who have been no experience of ECT were more worried about adverse effects, doctors who experienced practicing ECT thought preferably the aspect of safety and potent effects of ECT. Psychiatrists who prefer psychotherapy were more likely to concern about adverse effect of ECT, but there were no differences in other aspects when compared with others. Most psychiatrists participated in this survey had positive attitudes about application of ECT to geriatric patients, but negative at child&adolescent patients. CONCLUSION: Authors recognized that many Korean psychiatrists agreed with performing ECT, and expected good results, but in reality, it is difficult to expect for them to perform ECT. Several factors may be associated for that: the changes in trend of psychiatric treatment, production of novel psychotropic drugs, researches trends which pharmacotherapy is prevailing in the fields of psychiatry, and problems of education, that is, lack of standard educational curriculums and systemic training course at residency for ECT.

OBJECTIVES: Patients with poor insight are commonly observed among schizophrenics and they show poor drug compliance and prognosis. This study aimed at examining the characteristics of psychopathology in patients with schizophrenia who have no insight. Understanding the features of inner psychopathology in schizophrenic patients with poor insight, we assumed, could lead to insight-promoting clues. METHODS: The subjects consisted of 69 patients with schizophrenia diagnosed by DSM-IV criteria. For identifying insight level in the patients, Scale to Assess Unawareness of Mental Disorder(SUMD) was applied. After subjects were divided into two groups depending upon insight level, psychopathological differences were evaluated by Kyung Hee-Frankfruter Beschwerde Fragebogen(K-FBF), which was known as one of the subjective psychological tests for the schizophrenics. RESULTS: There was no significant differences in demographic variables, duration of illness, and dose of medication between two groups. However, significantly high rate of involuntary admission and tendency of high frequency of admission were revealed in schizophrenic patients with poor insight. And, also poor insight group showed significantly high scores in the factors of sensorimotor disorder(subscales of psychomotor disorder, perceptual disorder and blocking symptoms included) and in language-cognitive disorder factor(subscales of language disorder and cognitive floating included) compared with patients who have insight. CONCLUSION: We was assumed that lack of insight in schizophrenics could include one of the symptoms based on neuropsychological or neurobiological abnormalities in brain. Moreover, it was revealed that patients with poor insight evaluated themselves as having more serious psychopathologies than patients who had insight. It has been already known that schizophrenic patients who lack in insight are reluctant to taking psychiatric care and lack in awareness of their illness. However, this study suggests that their inner psychopathology associated with insight can be understood with the use of subjective psychological test, i.e. K-FBF. For understanding the schizophrenic patients who lack in insight, not only checking the insight but also applying the subjective test such as K-FBF seems to be helpful.

BACKGROUND: Inducible heat shock protein 70s (iHSP70) are expressed by stressful stimuli that result in protein denaturation, and are thought to assist in the maintenance of cellular integrity and viability. In addition, iHSP70 is known to be a sensitive marker of neuronal injury. To my best knowledge, no previous studies have been documented on iHSP70 induction by nociceptive impulse transmission through peripheral nerves not by direct neural damage. The purpose of this study was to examine the hypothesis that iHSP70 can be expressed in the nervous system, which is related to the dental nociceptive pathway, by tooth pulp inflammation. METHODS: The pulp of rat mandibular molars was exposed. Animals were sacrificed at 1, 4, and 7 days after pulpal exposure, and the pulps were evaluated histologically. Also, iHSP70 levels were examined in the Gasserian ganglion (GG) and the trigeminal sensory nucleus (TSN). RESULTS: At 4 days after pulpal exposure, iHSP70 was significantly more expressed in the ipsilateral GG than in the contralateral GG. In the histological study, inflammation was found in the entire pulp tissue at 4 days. There were no significant differences in iHSP70 levels between the ipsilateral TSN and the contralateral TSN. Also, there were no significant differences in iHSP70 expression of GG and TSN between both sides at 1 and 7 days after pulpal exposure. CONCLUSIONS: These results suggest that iHSP70 can be expressed in the GG at 4 days after pulpal exposure by nociceptive impulses due to pulpal inflammation.

The multifactorial hypothesis is proposed as a working hypothesis which encompass both the genetic and environmental factors known to participate in the etiology of congenital heart malformations. So, it is believed that avoidance of suspected environmental factors in early pregnancy is the most certain preventive measure of congenital heart malformations. This study has been undertaken in order to find the possible environmental risk factors for congenital heart malformations in Korea. A total of 114 mothers of first graders of the elementary schools with congenital heart malformations confirmed through the screening program in Kyonggi Province from 1992 to 1995 were included as cases. And 206 mothers of healthy students matched by sex and elementary schools comprised the control group. Environmental risk factors including drug use during the first trimester of pregnancy, and other confounders were collected by telephone interview using standardized questionnaires by well trained interviewers. The result of multivariate logistic regression analysis showed that congenital heart malformation were associated with family history of congenital heart malformations(OR=2.94, 95% CI: 1.08, 7.96), the order of birth(OR=0.49, 95% CI: 0.31, 0.79). And the coffee consumption over 14 cups/week during early pregnancy showed marginal significance(OR=3.52, 95%CI: 0.98, 12.62). The mother's age at the subject birth and father's smoking at home were significant in linear trend test(p<0.05). It is recommended that the genetic counselling and the avoidance of known environmental risk factors in early pregnancy were needed to prevent congenital heart malformations.

Clinics in Orthopedic Surgery 2019;11(3):344-351
BACKGROUND: Although secondary cervicothoracic scoliosis frequently occurs in patients with congenital muscular torticollis (CMT), the relationship between scoliosis and CMT has not been evaluated. This study aims to evaluate the effects of surgical release of sternocleidomastoid (SCM) muscle on secondary cervicothoracic scoliosis in patients with CMT and determine factors affecting the improvement of scoliosis after surgical release of SCM muscle. METHODS: Eighty-seven of the 106 patients, confirmed as having secondary cervicothoracic scoliosis with CMT with a minimum 1-year follow-up, were included in this study. Preoperative and last follow-up radiologic outcomes were assessed for the cervicomandibular angle (CMA), Cobb angle of the cervicothoracic scoliosis, and direction of convexity in the scoliosis curve. Patients were divided into two groups to assess the improvement of Cobb angle according to residual growth potential; age ≤ 15 years and > 15 years. The improvement of Cobb angle after surgical release was compared in the two groups. Correlation analysis and multivariable regression analysis were performed to determine the factors affecting the improvement of scoliosis. RESULTS: All the radiologic parameters, such as the Cobb angle and CMA, improved significantly after surgical release (p < 0.001). The improvement of Cobb angle was significantly higher in age ≤ 15 years than in age > 15 years (p < 0.001). The improvement of Cobb angle was significantly correlated with age (r = −0.474, p < 0.001) and the preoperative Cobb angle (r = 0.221, p = 0.036). In multivariable regression analysis, age and preoperative Cobb angle were shown to be predisposing factors affecting the improvement of scoliosis. CONCLUSIONS: The results showed that SCM release can be a beneficial treatment for secondary cervicothoracic scoliosis. The improvement of scoliosis was greater when the SCM release was performed before the patient reached the end of growth.

Pulmonary gangrene is a rare complication of severe pulmonary infection in which a pulmonary segment or lobe is sloughed. It is a part of a spectrum of disease in which lung tissue is devitalized(such as necrotizing pneumonia, pulmonary abscess), but apart from them, pulmonary gangrene has mo re extensive area of necrosis and thrombosis of large vessels plays a prominent role in the pathogenesis. We experienced a case of pulmonary gangrene in 71 year old female obstructive pneumonia patient with non-small cell lung carcinoma. She complained high fever, chill and despite treatment with antibiotics, pneumonia progressed to empyema. At that time chest radiograph showed a large cavity including sloughed lung tissue, freely moving to dependent position at both lateral decubitus view. RML and RLL were resected and compression of pulmonary vessels by enlarged lymph nodes was observed. Defervescence was obtained immediate postoperative period and the patient was discharged after infection control with antibiotics, chest tube drainage. The perivascular ly mph nodes dissected during lobectomy were proved to be reactive hyperplasias. We speculated that the carcinoma caused obstructive pneumonia, in turn, resulted in reactive hyperplasia of the draining lymph nodes surrounding the large vessels and finally the lung tissues supplied by them necrotized and sloughed.
