Total anomalous pulmonary venous return(connection) is a congenital heart disease. Especially, the reports of the patients with double connections of all pulmonary veins were rare. An infant who underwent operation for total anomalous pulmonary venous return had double drainge of all pulmonary veins to both left vertical vein and anomalous descending vein. This second lesion was not diagnosed preoperatively, but in operative field. Operative treatments were performed by ligation of left vertical vein and central pulmonary vein-to-left atrium anastomosis without ligation of the descending anomalous vein. For these less common variants fo total anomalous pulmonary venous return,a more detailed and precise understanding of morphology can facilitate accurate surgical repair. And also, early detection of the disease is an another issue for a good prognosis.

Clear cell sarcoma (CCS), also called malignant melanoma of soft parts, is a rare malignant soft tissue tumor and is often associated with tendons or aponeuroses. Most of CCS involve extremities, especially lower extremities, but a tumor occurring in the trunk is rare. We report an extremely rare case of CCS originated in the upper thoracic back muscle. To our knowledge, this case is the second report of CCS of the back muscle.

Korean Journal of Spine 2008;5(1):36-38
A spinal synovial cyst is an uncommon lesion associated with degenerative spinal arthropathy. It can cause radicular symptoms and may masquerade clinically as other, more common entities. A 50-year-old female presented with an intraspinal synovial cyst at the L5-S1 level manifesting as lower back pain and right leg pain. The patient's clinical symptoms improved after surgical management. Intraspinal synovial cyst should be considered in the differential diagnosis of the patients presenting with acute radicular symptoms.

PURPOSE: To investigate the localization and functional lateralization of the supplementary motor area (SMA) in motor activation tests in comparison to that of the primary motor area. MATERIALS AND METHODS: Seven healthy volunteers obtained echoplanar imaging blood oxygen level dependent technique. This study was carried on 1.5T Siemens Magneton Vision system with the standard head coil. Parameters of EPI were followed as ; TR/TE; 1.0/66.0 msec. flip angle : 90degree, field of view : 22cmx22cm, matrix : 128x128, slice number/slice thickness/gap : 10/4mm/0.8mm with fat suppression technique. Motor task as finger opposition in each hand consisted of 3 sets of alternative rest and activation periods. Postprocessing were done on Stimulate 5.0 by using cross-correlation statistics. To compare the functional lateralization of the SMA in the right and left hand tests, each examination was evaluation for the percent change of signal intensity and the number of activated voxels both in the SMA and in the primary motor area. Hemispheric asymmetry was defined as difference of summation of the activated yokels between each hemisphere. RESULTS: Percent change of signal intensity in the SMA (2.49-3.06%) is lower than that of primary motor area(4.4-7.23%). Percent change of signal intensity including activated voxels were observed almost equally in the right and left SMA. As for summation of activated voxels primary motor area had significant difference between each hemisphere but not did the SMA. CONCLUSION: Preferred contralateral dominant hemisphere and hemispheric asymmetry were detected in the primary motor area but not in the SMA.

Epidermolytic keratosis palmaris is a rare disease which shows clinical findings of Unna Thost keratoderma and histopathologic of epidermolytic hyperkeratosis. We report herein a case of epidermolytic keratosis palmaris et plantaris in a 16-month-old female baby. Light microscopy shows marked hyperkeratosis, large irregular keratohyalin granules, and large clear spaces in the granular and upper spinous layers. Eletron microscopic findings shows that the clear spaces are areas of cytoplasm filled with a fibrillar material and cellular organelles. Abnormal clumping of tonofilament and keratohyalin is also present.

Journal of the Korean Cleft Palate-Craniofacial Association 2002;3(2):185-189
An upward slant of palpebral fissure is usually said and believed to be a hallmark of Mongolian race. The slant of palpebral fissure is very important in the evaluation and treatment of patients with congenital deformities. And these statistical values of slant of palpebral fissures are very helpful in case of traumatic or congenital lateral canthal deformities and upper face lift or forehead lift. The normal values of slant of palpebral fissures are variable according to races, sex and ages. Even if upward slant of palpebral fissure are one of characteristic features of Koreans, there are a few articles concerning them in Korea yet, unfortunately. So, we have inevitably utilized the Caucasian or Japanese statistical data. Authors measured the slant of palpebral fissure in Koreans, and statistically analyzed them in 996 individuals including 468 males and 528 females. The mean values of slant of palpebral fissure was 8.5+/-2.0degreein males and 8.8+/-2.5degreein females. The mean values of slant of palpebral fissure was greater in female than male. However, there was no statistical difference between males and females. The slant of palpebral fissure reached the peak level at childhood and teenagers in a great portion. After the peak level, the changing pattern of slant of palpebral fissure was decreasing gradually. In summary, we consider 8.65degreeas normal standard value of slant of palpebral fissure when performing lateral canthal surgery in Koreans.

METHODS: We investigated and compared the epidemiologic characteristics of the E. cloacae isolation in the period of outbreak (April-June, 1998) with those in the control period (January-March, 1998). To identify the risk factors for E. cloacae sepsis, we retrospectively conducted a chart review for the patients who had E. cloacae sepsis during the period of outbreak. On the basis of these results, environmental culture was performed hospital wide. RESULTS: Ten clinical isolates E. cloacae were recovered from the blood of ten patients from April to June. 1998. Seven out of 10 patients recieved ERCP procedure just before E. cloacae sepsis. Hence, we performed surveillance study in the endoscopy room before and after the procedure. The survey showed that distilled water which was used for washing the endoscopy was contaminated with E. cloacae, which was suspected to be the common source of this outbreak. Therefore, we changed distilled water into sterilized distilled water on washing the endoscopy. After this correction was performed, the incidence of ERCP-associated E. cloacae sepsis declined markedly (P<0.011). CONCLUSION: We investigated an outbreak of ERCP-related E. cloacae sepsis and the outbreak was successfully controlled by removing the source of infection.

OBJECTIVE: Although the prevalence of pulmonary tuberculosis has decreased progressively after the national control program for tuberculosis began, nowadays the number of MDRTB is increasing seriously. MDRTB tends to be poor responsive to current antituberculosis regimens. It is mainly due to poor compliance, high rate of side reaction of secondary drugs, and limitation in number of available drugs. The purpose of present study is to evaluate the clinical features of pulmonary tuberculosis patients admitted in one national tuberculosis hospital and to expose the problems pertaining to current remedies, to increase the treatment efficacy for pulmonary tuberculosis including MDRTB in the end. METHOD: Retrospective analysis of 336 pulmonary tuberculosis patients admitted in National Masan Tuberculosis Hospital was done. Contents of analysis were patients profile, the first diagnosed time and medical institutes, family history, residence, previous treatment history, chief complaints at the time of admission, lesion site on chest X-ray film, combined deseases, side reaction to antibuberculosis drugs, used drugs before admission and the results of drug sensitivity test. RESULTS: The ratio between male and female was 4:1. Age showed relatively even distribution from 3rd to 6 th decades. 64.6% of the patients was diagnosed at public health center. Weight loss was the most common complaint at admission. Bilateral lesions on chest X-ray films were 59.8%. 1 30patients had combined desease, of which DM was the most common(37.7%). 95patients had family history, of which parents were the most common(41.7%). According to the time of first diagnosis, 31 patients were diagnosed before 1980, and after then the number of patients was increased by degrees Residence overwhelmed in pusan and gyung-nam province. 258 patients got previous treatment history, of which 112 patients(43.4%) had more than 3 times and only 133 patients(51.6%) got regular medication. 97 patients used more than other 3 drugs in addition to INH, EMB, RFP and PZA before admission. 154 patients were informed with the results of drug sensitivity test. of which 77 patients had resistance to more than 5 drugs. Gastrointestinal problem was the most common in side reaction to drugs. CONCLUSION: In the case of weigt loss of unknown cause, tuberculosis should be suspected. In first treatment, sufficient and satisfactory explanation for tuberculosis is necessary and treatment period should not be stict to 6 month-short term therapy. In retreatment, new drugs should not be added to used drugs enen though drug sensitivity restlts show sensitivity to some of them. Proper time for surgical intervention should not be delayed.
