A case of ischemic colitis in ascending colon mimicking colon cancer / 대한내과학회지

Ischemic colitis is recognized as the most common vascular disorder of the intestines in the elderly. Correct diagnosis is usually made after the ischemic episide is over and ischemic colitis is frequently misdiagnosed. A case is presented in which an initial diagnosis of appendicitis was made. On operation, a tumor like mass was found in ascending colon. Pathological examination revealed ischemic colitis. We report a case of ischemic colitis in ascending colon mimicking colon cancer.

A case of cervical lymphadenitis by toxoplasmosis / 대한내과학회지

Toxoplasma lymphadenitis is the most common clinical manifestation of toxoplasmosis in an immunocompetent host. The cervical lymph nodes are the most commonly involved, whereas systemic manifestations are rare. The most common clinical presentations are asymptomatic or subclinical, with fever, maculopapular rash, and general malaise. In immunocompromised patients, the presentations may be devastating with disseminated disease resulting in encephalitis, myocarditis, and pneumonia. We are reporting a case of toxoplasma lymphadenitis in an immunocompetent host diagnosed by histologic and serologic evaluation.

A case of small intestinal obstruction due to phytobezoar, revealed after operation in elderly / 대한내과학회지

The major causes of small bowel obstruction are postoperative adhesion, hernia, intussusception and malignancies. However, in cases of uncommon causes of small bowel obstruction, surgeons are in a dilemma because the preoperative diagnosis and making a decision to operate are frequently difficult and delayed. Phytobezoars are unusual cause of small bowel obstruction. They are mostly due to ingestion of stringent immature fruits following gastric surgery. They are usually formed in stomach and do not migrate to the other intestinal tract, but can lead to the serious complication of acute small bowel obstruction. We are reporting a case of acute small bowel obstruction due to phytobezoar about 2x2x3 cm3 size in a 90 year old female.

A Case of Polymyos itis Associated with Liver Cirrhosis

Polymyositis is uncommon connective tissue disease of autoimmune etiology in which the skeletal muscle is damaged by a inflammatory process dominated by lymphocytic infiltration. Polymyositis has been associated with several viral infections, and a spectrum of immune-related diseases may occur with hepatitis C virus(HCV) infection. However, no association between polymyositis and HCV infection has been reported previously. We report a case of polymyositis combined with liver cirrhosis who had evidence of HCV infection.

Outcome of Early Diagnos is and Hemodialys is in Acute Renal Failure due to Metformin-associated Lactic Acidosis in Elderly Type 2 Diabetes Mellitus Patient

Metformin is a biguanide oral hypoglycemic agent commonly used in the treatment of diabetes mellitus. Metfofmin is excreated largely by the kidney and binds only negligibly to plasma proteins. Toxicity is usually seen when metformin is prescribed to patients with renal insufficiency. Lactic acidosis in diabetics on metformin therapy is rare but still associated with poor prognosis. For an early diagnosis, clinical symptoms of intoxication should be well known by physicians and patients. First-line therapy for correction of lactic acidosis and effective elimination of metformin is bicarbonate hemodialysis. We report a case of acute renal failure due to metformin-associated lactic acidosis in elderly type 2 diabetes mellitus patient and she was successfully treated by hemodialysis with bicarbonate buffer.

A Case of Paroxymal Ventricular Tachycardia Improved due to Electrical Defibrillation was done Repeatedly in Patient with Ce rebral Infarction

Paroxymal ventricular tachycardia occurs most frequently during the first several months following myocardial infarction, although the risk of arrhythmia development continues for many years. Underlying disease was coronary artery disease, dilated or hypertrophic cardiomyopathy, valvular heart disease, myocarditis, and idiopathic. Idiopathic ventricular tachycardia may be the most common type in Korea and usually originates from either right ventricular outflow tract or left ventricular septum. For the emergency treatment of sustained, hemodynamically stable ventricular tachycardia, antiarrhythmic drugs are the therapy of choice(choice of therapy). Mostly class I antiarrhythmic drugs, such as lidocaine, are preferred. In hemodynamically unstable ventricular tachycardia, electrical defibrillation should be applied, in case of recurrences, followed by pharmacological treatment with class I antiarrhythmic drugs or amiodarone. We report a case of paroxymal ventricular tachycardia improved due to(by) electrical defibrillation was done repeaedly in patient with cerebral infarction.

A case of localized fibrous tumor of the pleura presenting with hypoglycemia / 대한내과학회지

Localized fibrous tumor of the pleura is rare, slowly growing, benign tumor. Most of these tumors clinically behave asymptomatically, although tumor-associated hypoglycemia occurs in a few cases and lead to hypoglycemic coma. Laboratory investigations show elevation of IGF-II with a 2-3 times higher effect on the blood glucose level than insulin. Surgical resection of the tumor is recommended. We report on the case of a 81-year-old man, who complained of hypoglycemic episodes. Diagnostic evaluation showed a fibrous tumor of pleura attached to the right diaphragm.
