The majority of injections intended to be intramuscular are actually delivered into fat in the area of thebuttock in most of the patients having a thick gluteal fat layer. Injections of some drugs can cause tissuenecrosis that ensues in scar formation and often in dystrophic calcifiation giving rise to ring-like densities inantero-posterior radiographs of the pelvis. We studied the incidence and characteristics of calcifications in thebuttocks frequently noted in pelvic radiographs and whether they have any relationship with thickness anddistribution pattern of the fat layer in the buttocks. Pelvic radiograms of 220 consecutive patients (110 malesand 110 females) with the age ranging from 16 to 76 years(average 39) were reviewed. The area of buttock was divided arbitrarily into four quadrants by the vertical line crossing the center of the head of each femur and thehorizontal line connecting the summit of each femoral head, and the upper outer quadrant was further divided into four quadrants(Fig. 1). We measured the thickness of the extraperitoneal fat layer at the level where it cross theiliac crest bilaterally. The results were as follows; 1. Thirty out of 220 cases(14%) showed calcifications in thebuttock. 2. Calcifications in the buttock were much more frequent in female than in male (p<0.01). 3. Theincidence of calcifications increased with age(P<0.01) and with increase in fat layer thickness(P<0.01). 4,Calcifications in the buttock were mostly located at the upper outer quadrant of the buttock (78%). 5. Inconclusion, we assume that calcifications in the buttock are result of fat necrosis after injection into fatinstead of muscle.

We reviewed the computed tomography (CT) of 32 patients with upper lobe collapse to assess the significance of small atypically redistributed pleural effusion (ARPE) in distinguishing the bronchogenic carcinoma (BC) form tuberculosis (TB). Upper lobe collapse was caused by BC in 21 and by TB in 11 of the 32 patients. Small ARPE was Present in 14 of 21 patients with BC and two of the 11 patients with TB, Among 16 patients with small ARPE, CT showd mediastinal invasion in 11 (69%) patients and mediastinal lymphadenopathyn 6 (38%). Our results suggest that small ARPE associated with upper lobe collapse can be used a an auxiliary sign in the differential diagnosis between BC and TB.

OBJECTIVE: Despite the fact that facial emotion recognition (FER) tasks using Western faces should be applied with caution to non-Western participants or patients, there are few psychometrically sound and validated FER tasks featuring Easterners' facial expressions for emotions. Thus, we aimed to develop and establish the psychometric properties of the Korean Facial Emotion Identification Task (K-FEIT) and the Korean Facial Emotion Discrimination Task (K-FEDT) for individuals with schizophrenia. METHODS: The K-FEIT and K-FEDT were administered to 42 Korean individuals with schizophrenia to evaluate their psychometric properties. To test the convergent and divergent validities, the Social Behavior Sequencing Task (SBST) and hinting task were administered as social-cognitive measures, and the Trail Making Test (TMT)-A and -B were administered as neurocognitive measures. RESULTS: Average accuracy on the K-FEIT and K-FEDT were 63% and 74%, respectively, and internal consistencies of the K-FEIT and K-FEDT were 0.82 and 0.95, respectively. The K-FEIT and K-FEDT were significantly correlated with SBST and Hinting Task, but not with TMT-A and B. CONCLUSION: Following replication studies in a larger sample, the K-FEIT and K-FEDT are expected to facilitate future studies targeting facial emotion recognition in schizophrenia in Korea. Limitations and directions for future research are discussed.

Since the entity of postmastectomy lymphangiosarcoma was first reported by Stewart and Traves in 1948, postmastectomy lymphangiosarcoma has become a well recognized, uncommon malignant tumor which occurs in the upper extremity following mastectomy for mammary carcinoma. The postmastectomy lymphangiosarcoma occurred at an average age of 63.9 years and at an average of 10 years and 3 months following mastectomy. The lymphangiosarcoma raised from blood and lymphatic vessel. The histologic appearance has been observed edematous dermis and dilated lymphatics lining with malignant cells. Most authors recommend radical amputation for treatment, either shoulder disarticulation or forequarter amputation. Other modalities of treatment including radiotherapy were considered as ineffective. The present report provides a case of the regression of postmastectomy lymphangiosarcoma with chronic lymphedima by external irradiation. Radiation therapy was used as primary therapy. Total tumor dose of 6500 cgy in 9 weeks was delivered using 6 MV x-ray and 8 MeV electron.

OBJECTIVE: Childhood trauma is recognized as an important risk factor in suicidal ideation, however it is not fully understood how the different types of childhood maltreatment influence suicidal ideation nor what variables mediate the relationship between childhood trauma and suicidal ideation. This study examined the path from childhood trauma to suicidal ideation, including potential mediators. METHODS: A sample of 211 healthy adults completed the Childhood Trauma Questionnaire (CTQ), Beck scale for Suicidal Ideation (BSI), Functional Social Support Questionnaire (FSSQ) and Hospital Anxiety and Depression Scale (HADS). Path analysis was used to investigate the relationship among study variables. RESULTS: Of the several types of childhood maltreatment we considered, only childhood sexual abuse directly predicted suicidal ideation (β=0.215, p=0.001). Childhood physical abuse (β=0.049, 95% confidence interval: 0.011–0.109) and childhood emotional abuse (β=0.042, 95% confidence interval: 0.001–0.107) indirectly predicted suicidal ideation through their association with anxiety. Childhood neglect indirectly predicted suicidal ideation through association with perceived social support (β=0.085, 95% confidence interval: 0.041–0.154). CONCLUSION: Our results confirmed that childhood sexual abuse is a strong predictor of suicidal ideation. Perceived social support mediated the relationship between suicidal ideation and neglect. Anxiety fully mediated the relationship between suicidal ideation and both physical abuse and emotional abuse. Interventions to reduce suicidal ideation among survivors of childhood trauma should focus on anxiety symptoms and attempt to increase their social support.

Adult intussusception is a rare condition, unlike in children. Ihere is an identifiable bowel lesion as a leading point in most of cases. Retrospectively we reviewed 22 patients with adult intussusception, and analyzed CT scans of 13 patients during the last 5 years. Twenty of the 22 patients had various causes of intussusception and 7 patients were associated with primary malignancy, 5 patients with benign tumor, and 4 patients with adhesive band. CT scans of 13 cases all showed characteristic target appearance or sausage-like soft tissue mass within the bowel, suggesting intussusception. In eleven of the 13 patients(84.6%) an intussuscepting mass was identified on CT scan as the lead point. Specific diagnosis for the cause of intussusception could be made by CT in four of 13 cases (three lipomas and one mucocele). In conclusion, CT is useful not only for the diagnosis but also for the evaluation of the leading causes of intussusception. Especially, CT could determined the exact cause of intussusception in cases of lipoma and mucocele.

It was already reported in else where that a standard linear accelerator, with only slight modification can function in a manner similar to Leksell's Gamma unit device in the treatment of inoperable deep seated intracranial lesions. Using collimated narrow beams, a localization system and special computer programs for precise patient positioning and a high concentration of irradiation dose within the lesions, eleven patients with AVMs and brain tumor have now been treated since 1988. The 6 MeV linear accelerator and Hitchcock stereotactic frame was used of the all procedures. In 10 of the 11 patients, no side effects occurred. The first 7 patients, who could be observed 3 months or longer have been studied radiologically and clinically. In 6 patients marked decrease in contrast enhancement and sometimes dramatic clinical improvement was achieved. In one case a marked increase of the surrounding brain edema occurred 7days after radiosurgery, who was operated on. The radiantion dose was based on the volume, location and radiosensitivity of the lesion which ranged 15-40 Gy.
