Gastric Perforation Caused by Primary Gastric Diffuse Large B Cell Lymphoma / 대한소화기학회지

Spontaneous gastric perforation is a rare complication of gastric lymphoma that is potentially life threatening since it can progress to sepsis and multi-organ failure. Morbidity also increases due to prolonged hospitalization and delay in initiating chemotherapy. Therefore prompt diagnosis and appropriate treatment is critical to improve prognosis. A 64-year-old man presented to the emergency department with severe abdominal pain. Chest X-ray showed free air below the right diaphragm. Abdominal CT scan also demonstrated free air in the peritoneal cavity with large wall defect in the lesser curvature of gastric lower body. Therefore, the patient underwent emergency operation and primary closure was done. Pathologic specimen obtained during surgery was compatible to diffuse large B cell lymphoma. Fifteen days after primary closure, the patient received subtotal gastrectomy and chemotherapy was initiated after recovery. Patient is currently being followed-up at outpatient department without any particular complications. Herein, we report a rare case of gastric lymphoma that initially presented as peritonitis because of spontaneous gastric perforation.

3 Cases of Portal Vein Thrombosis in Hepatocellular Carcinoma and Liver Cirrhosis Treated with Anticoagulation

The reported prevalence of PVT is in the range of 0.6-15.8% in patient with liver cirrhosis or portal hypertension. If the patient has hepatocellular carcinoma, thrombus is likely to be malignant thrombus. Malignancy, frequently of hepatic origin, is responsible for 21-24% of over all cases. The overall mortality rate of chronic PVT has been reported to be less than 10%, but is increased to 26% when associated with hepatocellular carcinoma and cirrhosis. However, no treatment guideline has been established on anticoagulant therapy for PVT in patients with concomitant hepatocellular carcinoma and cirrhosis. Because actually it is not easy to distinguish between malignant thrombus and benign thrombus in clinical aspect, PVT in hepatocellular carcinoma are still debatable whether or not treatment when it diagnosed. We present 3 cases of portal vein thrombosis successfully treated with anticoagulation in hepatocellular carcinoma and liver cirrhosis, and we include a literature review.

The AIMS65 Score Is a Useful Predictor of Mortality in Patients with Nonvariceal Upper Gastrointestinal Bleeding: Urgent Endoscopy in Patients with High AIMS65 Scores

BACKGROUND/AIMS: To validate the AIMS65 score for predicting mortality of patients with nonvariceal upper gastrointestinal bleeding and to evaluate the effectiveness of urgent ( or =2) were allocated to either the urgent or non-urgent endoscopic procedure group. In-hospital mortality, success of endoscopic procedure, recurrence of bleeding, admission period, and dose of transfusion were compared between groups. RESULTS: A total of 634 patients were analyzed. The AIMS65 score successfully predicted mortality (AUROC=0.943; 95% confidence interval [CI], 0.876 to 0.99) and was superior to the Rockall score (AUROC=0.856; 95% CI, 0.743 to 0.969) in predicting mortality. The group with high AIMS65 score included 200 patients. The urgent endoscopic procedure group had reduced hospitalization periods (p<0.05) CONCLUSIONS: AIMS65 score may be useful in predicting mortality in patients with nonvariceal upper gastrointestinal bleeding. Urgent endoscopic procedures in patients with high scores may be related to reduced hospitalization periods.

Late Postoperative Anterograde Jejunojejunal Intussusception after Total Gastrectomy with Loop Esophagojejunostomy

Anterograde jejunojejunal intussusception after total gastrectomy is a very rare postoperative complication. We report a 54-year-old man with a history of total gastrectomy, uncut Roux-en-Y gastric bypass, and Braun's jejunojejunal anastomosis. An upper gastrointestinal endoscopy revealed a bulky, reddish mass in the efferent loop with congestion, edema, and mucosal bleeding. An emergency computed tomography showed a target-like multilayered wall thickening in the afferent loop and a lamellar structure arranged in a concentric circle. Surgical exploration revealed an anterograde intussusception of the afferent proximal jejunum adjacent to the jejunojejunostomy site. This is a very uncommon occurrence because most intussusceptions after total gastrectomy are of the retrograde type. Moreover, anterograde jejunojejunal intussusception tends to occur in the early postoperative period. We report a case of late postoperative anterograde jejunojejunal intussusception after total gastrectomy with Braun's jejunojejunal anastomosis in a 54-year-old Korean man and review the related literature.

A Case of Psoas Abscess Caused by Candida glabrata / 감염과화학요법

Infections due to Candida species are becoming more frequent in several patient population and settings. The proportion of non-albicans Candida spp. causing candidemia has increased during the recent decades. Especially, fungaemia due to Candida glabrata has reduced susceptibility to azoles. We report a case of iliopsoas abscess caused by Candida glabrata. A 51-year-old male diabetic patient was admitted with fever and both hip joint pain. Abdominal CT scan revealed huge left iliopsoas intramuscular abscess and left perinephric abscess. The abscess was drained percutaneously. Cultures of the pus were positive for Candida glabrata. The patient's condition improved after abscess drainage and was discharged with oral antifungal agent.

A Case of Acute Human Immunodeficiency Virus Syndrome Manifesting as Seizure / 감염과화학요법

Acute human immunodeficiency virus (HIV) syndrome is defined as transient symptomatic illness associated with high-titer HIV replication and an expansive immunologic response to the invading pathogen. Seizure and epilepsy are not rare among the HIV-infected patients. Major causes of HIV-related seizure are focal brain lesion, meningitis, metabolic derangement, and no identified causes other than HIV itself. Generally, seizure in HIV infected patients develops during the advanced stages of the disease; decreased immunity and increased chances of developing opportunistic infection in the central nervous system (CNS) predispose them to have seizures attacks. We report a case of acute HIV syndrome which presented as new-onset seizure. Since no evidence of focal brain lesion or any opportunistic infection could be found, the most probable cause of seizure could be attributed to acute HIV syndrome. The patient got better after taking anti-epileptic drug and there have been no further recurrence of episodes so far.

A case of aortic thromboembolism and fresh nephrotic syndrome / 대한내과학회지

Nephrotic syndrome has frequently been associated with complications of thrombosis. Hypercoagulability is known as the principal contributing factor in the pathophysiologic mechanism, but the precise mechanism is unclear. Venous thrombosis is frequently recognized, but arterial thrombosis is rare, especially in the abdominal aorta. Most cases of arterial thrombosis present with acute ischemic symptoms and develop into a relapsing phase of nephrotic syndrome. The mainstream treatment for all abdominal aortic thrombosis patients is an emergency thrombectomy and thrombolytic therapy. We report on a 63-year-old male patient who was referred for malignant hypertension. The patient had no symptoms of claudication or peripheral ischemia. We diagnosed nephrotic syndrome using the laboratory data and detected a thrombosis involving the abdominal aortic, left renal and both iliac arteries. Because the patient had a single functioning kidney, we did not perform a kidney biopsy. We consider that the hypercoagulability state in nephrotic syndrome was caused by the abdominal aorta and peripheral arterial thrombosis. The patient's symptoms improved after anticoagulation and conservative therapy.

Allopurinol-induced agranulocytosis in a patient on peritoneal dialysis / 대한내과학회지

Agranulocytosis is a rare, but sometimes dangerous, adverse reaction to allopurinol. We report the unusual case of a 43-year-old man with agranulocytosis, who received allopurinol while undergoing peritoneal dialysis. The bone marrow biopsy indicated that the agranulocytosis was drug-induced. After ceasing all drugs, isolating the patient, and administering granulocyte colony-stimulating factor (G-CSF), the leukocyte count returned to normal. A relationship between allopurinol therapy and agranulocytosis was presumed.

A case of severe metabolic acidosis after orthotopic neobladder replacement / 대한내과학회지

Following a radical cystectomy to treat bladder cancer, the ureters can be implanted in a short loop of ileum, which serves as an orthotopic bladder replacement. However, several investigators have reported the frequent development of a normal anion gap metabolic acidosis and electrolyte disturbance in these patients. The colon segments secrete sodium and bicarbonate ions and reabsorb ammonium, hydrogen, and chloride ions when exposed to urine, causing metabolic acidosis. In most cases, the acid-base disorder is not very troublesome. The metabolic acidosis can usually be corrected by administering sodium bicarbonate. We experienced a case of severe metabolic acidosis associated with urinary diversion that improved with continuous renal replacement therapy (CRRT).
