RESUMEN
Ischemic colitis is the most common form of intestinal ischemia. Although there are a variety of causes, the most common mechanism is acute, self-limited compromise in intestinal blood flow. Most cases of ischemic colitis are transient and resolve spontaneously, but right colon involvement is associated with poor outcome. Colonoscopy is the gold standard for the identification of colonic ischemia; however, very rarely, colonoscopy itself may induce ischemic colitis in patients with underlying predisposing factors, such as connective tissue disorders. We experienced a case of ischemic colitis of the right colon, following colonoscopy in a patient without risk factors.

Sparganosis is a rare parasitic disease caused by the migrating plerocercoid larva of tapeworms in the genus Spirometra. The most frequent clinical manifestation of human sparganosis is a subcutaneous nodule resembling neoplastic disease. Since the disease is relatively uncommon, even in endemic areas, sparganosis is rarely considered in the differential diagnosis of skin lesions. We experienced a case of sparganosis mimicking a skin metastasis in a patient with metastatic stomach cancer and made the diagnosis after an excisional tissue biopsy.

Esophageal submucosal dissection is a rare condition, resulting in the separation of the submucosa and muscle layer by mucosal laceration and bleeding. Possible causes are external trauma, foreign body entrapment, endoscopic instrumentation and even spontaneous dissection. Typical endoscopic findings show a false lumen from the torn mucosa and a muscle layer in the false lumen. Esophagography shows a "double barrelled" appearance. A dissection can be resolved with conservative management. We experienced a case of a submucosal dissection of the esophagus with perforation, an unusual complication of conscious sedation endoscopy.

Porphyria cutanea tarda (PCT) is a disease characterized by an early appearance of severe photosensitivity with an increase in urinary uroporphyrin excretion and other porphyrins, high isocoproporphyrin fecal levels and an accumulation of protoporphyrin in erythrocyte. This disease has been known to be caused by a dramatic decrease in the activity of the uroporphyrinogen decarboxylase. Multiple infectious and environmental factors may contribute to PCT by influencing oxidative stress in the hepatocytes. We report here on a case of porphyria cutanea tarda that presented with jaundice and photosensitivity.

With the increasing proportion of elderly and diabetic dialysis patients, permanent dual lumen catheters are becoming popular. One of the most frequent causes for the failure of hemodialysis in CRF patients with the tunneled cuffed catheter is the catheter dysfunction. It is thought to be due to encasement of the catheter by fibrin sleeve or fibrin sheath, kinking or malposition of the catheter. Catheter dysfunction due to fibrin sheath formation could sometimes be managed by reversal of arterial and venous lines, urokinase lock or infusion, and catheter exchange. Recently percutaneous fibrin sheath stripping (PFSS) became another modality of salvaging failing tunneled cuffed catheter before attempting catheter exchange. There was no report of applying PFSS to salvage the permanent dual lumen catheter in Korea. Authors recently experienced a case of successful application of PFSS to extend the life of catheter in a CRF patients as a last resort after failure of repeated urokinase trials. It is thought that PFSS is a simple and effective procedure which extends the longevity of permanent dual lumen catheter.

Calcium channel blockers are used to treat hypertension. Unwanted side effects associated with calcium channel blockers are facial flushing, headache, palpitation, dizziness, peripheral edema, constipation, indigestion, nausea, gingival hyperplasia, facial edema and fatigue. Gingival hyperplasia is a rare adverse effect of calcium channel blockers. Calcium channel blockers are known to contribute to gingival hyperplasia. Among all calcium-channel blockers, the prevalence of gingival hyperplasia is highest with nifedipine. Amlodipine is used extensively for the management of hypertension. Several cases have been published since 1994 indicating that amlodipine may also promote gingival hyperplasia. Amlodpine-induced gingival hyperplasia has not reported yet in Korea. We report a case of gingival hyperplasia caused by amlodipine.

Left pulmonary artery agenesis, accompanied by a coronary arterial fistula, is a very rare anomaly. Although unilateral pulmonary artery agenesis is associated with other cardiovascular defects, like as ventricular septal defect, patent ductus arteriosus, and tetralogy of fallot, this anomaly, accompanied by a coronary arterial fistula, has not yet been reported. Most patients with no associated cardiac anomalies have only minor, or absent, symptoms, and survive to adulthood, but some patients may suffer from recurrent respiratory infections and hemoptysis. The vessel to the affected lung in many of the proved cases has been described as arising from either the bronchial artery or the aortic arch. The blood supply from the coronary artery to the affected lung has never been reported. Recently, a case of left pulmonary artery agenesis, accompanied with a coronary arterial fistula was experienced, which was diagnosed by coronary angiography and a chest CT, which is presented, with the review of relevant literature.
