The authors presented a case of gastroschisis with a pedunculated gallbladder embedded in hepatic tissue. The patient was born after fullterm gestation. Due to extensive abdominal wall defect, she succumbed 3 days after birth. There was a pedunculated mass measuring 2.5x1.5x1.5 cm between the liver and distended stomach without any attachment to the liver. The pedicle of the mass was connected to the common bile duct. Cut surface revealed that the mass was an accessory hepatic lobe encircling the gallbladder. The histologic feature of both accessory liver and gallbladder was markedly altered probably due to vascular obstruction. We could find only a single similar case in literlature. That case was associated with Beckwith syndrome and ours was associated with large atrial spetal defect, large patent ductus arteriosus, accessory spleen as well as gastroschisis. The common feature of abdominal wall defect might be a predisposing factor.

We examined the p53 protein overexpression and evaluated its correlation with pathobiological variables, including: (1) patient age, sex, tumor size, histological type and grade, invasion depth, vascular invasion, perineural invasion and lymph node status; (2) the Ki-67 labeling index in 100 gastric carcinomas; and (3) the DNA ploidy pattern, S phase fraction (SPF), and the proliferation index (PI) in 84 cases using flow cytometry. The positive rate of p53 staining was 48% and the p53 immunoreactivity was independent of variable clinicopathologic factors. No correlation was made between the Ki-67 labeling index with p53 immunostaining and DNA ploidy parameters. Aneuploidy rate was slightly higher in the p53 positive group (55.6%) than the p53 negative group (44.4%)(p=0.097). The mean values of SPF and PI were significantly higher in the p53 protein positive group. Aneuploidy was more often observed in the intestinal type (p=0.038), advanced gastric carcinoma (p=0.015) and lymph node positive group(p=0.039). The above results suggest that although the p53 protein overexpression has no significant correlation with pathological factors and the Ki-67 labeling index, it may play an important role in tumor cell proliferation. Since p53 protein overexpression was slightly higher in the aneuploidy group showing significant correlation with poor prognostic parameters, it is thought that re-evaluation of the p53 mutation by molecular biological study is needed.

In Korea, slipped capital femoral epiphysis is a rare disease. In which the capital femoral epiphysis migrate posteriorly and inferiorly against the neck portion. Sometimes it should be differentiated from other conditions that separate the femoral capital epiphysis. We have experienced a rare case of separation of capital femoral epiphysis due to an osteosarcoma in the proximal femoral metaphysis in the 15 years of old girl.

Since the introduction of Holdsworth's new classification on fracture-dislocations of spine with particular emphasis on the role of posterior ligmaent complex, operative reduction and spinal fusion is considered to be an established procedure in treating unstable injuries of the thoracolumbar spine.By stabilizing unstable fractures,nursing, and rehabilitation become much easier. Among the various methods and devices, Harrington instrumentation and posterior spinal fusion have been used and found to be acceptable in our series. Twenty five consecutive patients with unstable fractures and fracture-dislocations' of thoracolumbar spine were treated by open reduction and spinal fusion with Harrington rod fixation at the Department of Orthopedic Surgery, Kang Nam General Hospital Public Corporation from the period of 1982 to 1985. The following results were obtained from analysis of the cases. l. Among 25 cases, 15 (60%) were due to flexion-rotation violence, 5 pure flexion,3 vertical compression, 1 shear fracture respectively. 2. Among 16 cases with neurologic deficit, 15 cases showed considerabel improvement after surgery. 3. Most of the cases showed satisfactory bony fusion, and average postoperative kyphotic angle was 14.4 after 3 months. 4. Although no particular external fixation was adopted, permitting mobility in bed, postoperative correction was relatively well maintained.

BACKGROUND/AIMS: We compared the accuracy in the diagnosis of hepatic masses such as hepatocellular carcinoma (HCC), metastasis and hemangioma using enhancing pattern alone with using additional findings, and determined whether the additional findings could improve the diagnostic accuracy. METHODS/MATERIALS: Triphasic spiral CT images were retrospectively analyzed in 83 cases of hepatic lesions,' 40 HCC, 21 metastases, and 22 hemangiomas. Three observers made the diagnosis first by the enhancement pattern of the mass alone, and then, by the whole information. The diagnosis of a lesion was considered correct if the lesion was correctly categorized by at least two observers. Diagnostic accuracies of two sessions were compared with McNemar test. RESULTS: Using enhancing patterns alone, 31/40 HCC (78%), 8/21 metastases (38%), 21/22 hemangiomas (95%) were correctly diagnosed. The frequency of correct diagnosis was significantly improved when all images with additional findings were used: 36/40 (90%) HCC, 20/21 (95%) metastases, 22/22 (100%) hemangiomas (P=0.00006). Metastasis showed most prominent and statistically significant improvement in the diagnostic accuracy (P=0.0004). The number of correct diagnoses for HCC increased without statistical significance (P=0.17). However, the images with additional findings did not significantly contribute to the diagnosis of hemangiomas. The additional finidngs those led to correct diagnosis of metastases were multiple mass (7 cases), coexistence of primary malignancy (6 cases), and metastasis to other organ (1 case). The findings of liver cirrhosis were helpful to diagnose HCC correctly in 5 cases. CONCLUSION: The enhancing pattems of tumors were important in the diagnosis of hepatic masses in spiral CT. However, the additional finidngs were also helpful for the diagnosis of hepatic masses especially for the masses with atypical enhancement pattern. In metastases, the additional findings such as multiple masses or detection of primary malignant focus were useful to diagnose correctly.

Among cystic tumors arising in the pancreas, microcystic adenoma is relatively uncommon; it is usually benign, and is comprised of cysts that vary in size from microscopic to 2cm in diameter. It has recently been reported to be associated with other pancreatic tumors with malignant potential; in particular, microcystic adenoma with coexistent islet cell tumor has been reported in von Hippel-Lindau disease. We report a case of microcystic adenoma of the pancreas associated with coexistent surgically-proven islet cell tumor. On spiral CT, the islet cell tumor was seen as a highly enhanced inhomogeneous solid mass in the pancreatic head, and microcystic adenoma as numerous small cysts throughout the pancreas.

Objectives : A diverse range of adverse effects has been linked to the application of antidepressants for the treatment of depressive disorder. Recently, evidence has been emerging of the adverse metabolic effects of antidepressants. This study investigated the effects of antidepressants on plasma glucose and other factors in the fat and muscle tissue relating to metabolism. METHODS : Long-Evans-Tokushima-Ostuka (LETO) rats were used to evaluate the effects of different antidepressants. Amitriptyline, fluoxetine, and mirtazapine were administered to each of three subgroups for 4 weeks, between 11 and 15 weeks old, while a fourth subgroup was administered no antidepressant during the same period. Changes of weight and daily intake were monitored. Tissues and blood were collected at 15 weeks. RESULTS : The fluoxetine subgroup showed lower weight gain and lower food efficacy ratio than did the other subgroups. Blood glucose and other circulating factors showed no significant differences among groups, except for the leptin levels of the fluoxetine subgroup. However, the amitriptyline and mirtazapine subgroups showed similar patterns in the response of mRNA expression of peroxisome proliferator-activated receptors gamma cofactor-1 and uncoupling protein-1, 2, 3. CONCLUSION : These results could indicate possible differences in metabolic response based on the kind of antidepressant used.

BACKGROUND AND PURPOSE: Recent randomized clinical trials (RCTs) have demonstrated benefits of endovascular recanalization therapy (ERT) contrary to earlier trials. We aimed to estimate the benefits of ERT added to standard therapy in acute ischemic stroke. METHODS: From a literature search of RCTs testing ERT, we performed a meta-analysis to estimate an overall efficacy and safety of ERT for all trials, stent-retriever trials, and RCTs comparing ERT and intravenous tissue plasminogen activator (IV-TPA). RESULTS: We identified 15 relevant RCTs including 2,899 patients. For all trials, ERT was associated with increased good outcomes (odds ratio [OR] 1.79; 95% confidence interval [CI] 1.34, 2.40; P<0.001) compared to the control. ERT also increased no or minimal disability outcomes, good neurological recovery, good activity of daily living, and recanalization. ERT did not significantly increase symptomatic intracranial hemorrhage (SICH) (OR 1.19; 95% CI 0.83, 1.69; P=0.345) or death (OR 0.87; 95% CI 0.71, 1.05; P=0.151). In contrast, ERT significantly reduced extreme disability or death (OR 0.77; 95% CI 0.61, 0.97; P=0.025). Restricting to five stent-retriever trials comparing ERT plus IV-TPA vs. IV-TPA alone, the benefit was even greater for good outcome (OR 2.39; 95% CI 1.88, 3.04; P<0.001) and extreme disability or death (OR 0.57; 95% CI 0.41, 0.78; P=0.001). Restricting to eight RCTs comparing ERT (plus IV-TPA in six trials) with IV-TPA alone showed similar efficacy and safety. CONCLUSIONS: This updated meta-analysis shows that ERT substantially improves clinical outcomes and reduces extreme disability or death without significantly increasing SICH compared to standard therapy.

A Case of disseminated cryptococcosis in a 5-year old girl is reported. Although twenty four pediatric cases of cryptococcosis were reported in Korea for the past 15years, this case's clinical picture is interesting and make diagnostic difficulties from miliary tuberculosis. She was transferred from a local clinic under the impression of miliary tuberculosis with chest X-ray showing miliary shadows. Mantoux test showed strong positive. She was not vaccinated BCG and had a history of contact with tuberculous patient for a month. Cough, fever and abdominal pain were persisted in spite of antituberculous medications(INH & RMP). CSF examination revealed cryptococcus cyst. Facial skin lesions which looked like Moluscum contagiosum at first became to be umbilicated and disseminated. It was diagtococcal lesions with little inflammatory response. In spite of treatment with 5-FC and Amphotericin B, her general condition became worse and died of respiratory failure. A brief review of the literature was done.

Coronary arteriovenous fistula (CAF) is most common form of hemodynamically significant coronary anomaly. CAF combined with atrial septal defect (ASD), however, constitutes an uncommon subgroup of CAF. We present a case of congenital CAF combined with secondum ASD, which are manifested by congestive heart failure. These anomalies were identified by transthoracic echocardiography and coronary angiography respectively. These ASD and CAF were closed by operation successfully without any complication.
