Successful Treatment of Cerebral Aspergillosis with Liposomal Amphotericin B and Minimal Invasive Surgery in a Patient Who Received Renal Transplant 10 Year Ago / 대한신장학회잡지

Aspergillosis involving central nervous system is a rare but life-threatening complication in renal transplant recipients. Its mortality rate approaches almost 100% in spite of various therapeutic regimens. We here report a case of successful treatment of brain aspergillosis with liposomal amphotericin B and endoscopic surgery. A 58-year- old renal transplant recipient admitted due to headache which was developed 5 months ago. He received renal transplant 10 years ago. After admission, brain MRI revealed brain abscess on frontal lobe and this was treated with antibiotics and amphotericin B. On 20 th hospital day, endoscopic surgery via intranasal approach was performed and pathologic finding was consistent with aspergillosis. During treatment, his graft function was progressively deteriorated(serum creatinine level 2.27 mg/dL 4.1 mg/dL) and amphoterinc B was replaced with ambisome. Thereafter, renal function was improved(serum creatinine 2.0 mg/dL on 46 th hospital day). Second operation was performed on 50 th hospital day to remove remnant pathologic lesion, and ambisome was continously adminstered. The brain MRI which was performed on 70 th hospital day showed much improvement. He was discharged with oral antifungal drug(itraconazole). Our case demonstrates the successful treatment of brain aspergillosis with medial treatment and minimal invasive surgery.

Successful Control of Double Tarchycardia Using Radiofrequency Catheter Ablation

A healthy 55-year-old man was referred for investigation of palpitations. During an episode of palpitation, the ECG documented two types of tachycardia with differing morphologies. One was a narrow QRS complex tachycardia with a heart rate of 140 beats/min. The other was wide QRS complex tachycardia with a heart rate of 210 beats/min. Transformation from one tachycardia to the other occurred spontaneously. Electrophysiological studies revealed two inducible tachycardia, which were shown to represent atrioventricular nodal reentrant tachycardia (AVNRT) and idiopathic left ventricular tachycardia. Radiofrequency catheter ablation of the slow atrioventricular nodal pathway resulted in alleviation of AVNRT. Following the ablation of AVNRT, the wide QRS complex tachycardia was induced during ventricular pacing. The mapping showed that the origin of the ventricular tachycardia was the mid-inferior wall of the left ventricle. Radiofrequency catheter ablation of the ventricular tachycardia resulted in mitigation cure of the idioventricular left ventricular tachycardia.

A Case of Infected Hepatic Cyst in a Patient with Adult Polycystic Kidney Disease / 대한신장학회잡지

Hepatic cysts are the most common extrarenal manifestations of adult polycystic kidney disease, but the hepatic cyst infection in a patient with polycystic kidney disease is rare. The infection may remain localized or may be followed by acute cholangitis or septicemia. The best management for infected hepatic cyst is drainage in combination with antibiotic therapy. We experienced a case of infected hepatic cyst in a patient with polycystic kidney disease in a 46-year-old man receiving hemodialysis. He presented with fever and abdominal pain and was found to have an infected liver cyst. Treatment with antibiotics and percutaneous drainage of the cyst resulted in clinical improvement. Thus, we report a case of infected hepatic cyst in a patient with polycystic kidney disease with review of the literature.

Protein Losing Enteropathy in a Patient with Henoch-Sch nlein Purpura: Successful Treatment with Steroid / 대한신장학회잡지

Although gastrointestinal manifestations are very common in patients with Henoch-Sch nlein purpura, protein losing enteropathy is a rare complication. We here report a case of protein losing enteropathy in a patient with Henoch-Sch nlein purpura. A 52-year old woman presented with lower abdominal pain, purpura and edema on lower extremity. Serum albumin was 1.9g/dL and 24 hour urine protein was 4.7g/ day. Skin and kidney biopsy revealed leukocytoclastic vasculitis and mesangial proliferative glomerulonephritis consistent with Henoch-Sch nlein purpura, respectively. Colonoscopy showed diffuse mucosal erosion at right colon. 99mTc-human serum albumin scintigraphy and fecal alpha-1-antitrypsin clearance confirmed protein losing enteropathy. The protein losing enteropathy improved with steroid treatment.
