RESUMEN
Pseudoepitheliomatous hyperplasia is a benign condition that may be caused by prolonged inflammation, chronic infection, and/or neoplastic conditions of the mucous membranes or skin. Due to its histological resemblance to well-differentiated squamous cell carcinoma, pseudoepitheliomatous hyperplasia may occasionally be misdiagnosed as squamous cell carcinoma. The importance of pseudoepitheliomatous hyperplasia is that it is a self-limited condition that must be distinguished from squamous cell carcinoma before invasive treatment. We report here on a rare case of esophageal pseudoepitheliomatous hyperplasia in a 67-year-old Korean woman with a lye-induced esophageal stricture. Although esophageal pseudoepitheliomatous hyperplasia is infrequently encountered, pseudoepitheliomatous hyperplasia should be considered in the differential diagnosis of esophageal lesions.

Immunoglobulin A (IgA) nephropathy associated with cirrhosis is the most common form of secondary IgA nephropathy (IgAN). Cirrhosis-related IgAN is usually clinically silent with a rare occurrence of gross hematuria, unlike in cases of idiopathic IgAN. Especially, acute tubular necrosis (ATN) associated with gross hematuria is very rare in cirrhosis-related IgAN, although acute renal failure is a frequently reported complication in advanced cirrhosis. Herein, we report an unusual case of ATN requiring renal replacement therapy, associated with gross hematuria in a patient with nonalcoholic, hepatitis B virus-associated cirrhosis. Results of a histopathological analysis revealed obstruction of the lumen of renal tubules by red blood cell casts, a marked tubular necrosis, and IgA deposition in the mesangium. The patient's renal function and gross hematuria were clearly improved after lamivudine treatment.

BACKGROUND: Measurement of peak expiratory flow rate (PEFR) in a follow-up examination for a chronic airway disease is useful because it has the advantages of being a simple measurement and can be repeated during examination. The aim of this study was to examine the annual decrease of PEFR in asthma and chronic obstructive pulmonary disease (COPD) patients and to confirm the factors which influence this decrease. METHODS: From May, 2003 to September, 2010, the annual decrease of PEFR was obtained from asthma and COPD patients attending an outpatient pulmonary clinic. PEFR was measured using a Mini-Wright peak flow meter (Clement Clarke International Ltd. UK), and we conducted an analysis of factors that influence the change of PEFR and its average values. RESULTS: The results showed an annual decrease of 1.70+/-12.86 L/min the asthmatic patients and an annual decrease of 10.3+/-7.32 L/min in the COPD patients. Age and FEV1 were the predictive factors influencing change in asthma, and FEV1 and smoking were the predictive factors influencing change in COPD. CONCLUSION: We confirmed the annual decreasing PEFR in patients with chronic airway disease and identified factors that work in conjunction with FEV1 to influence the change.

Dermatomyositis (DM) is rare systemic inflammatory disease with typical skin manifestations and muscular involvement. Various skin lesions can accompany this disease, such as Gottron's sign, Heliotrope rash, mechanic's hands, V sign and shawl sign. Scleredema is a very rare skin manifestation in DM. We report a case of DM in a 63-year-old woman, who had scleredema on her thighs. A diagnosis of DM was established by clinical manifestation, elevated muscle enzyme levels, electromyogram measures, and muscle biopsy findings. She was successfully treated with the immunosuppressants methotrexate, cyclosporine, and steroids (low dose).

Cefepime-induced nonconvulsive status epilepticus (NCSE) in end-stage renal disease (ESRD) patients receiving hemodialysis has only rarely been reported. Here we report a case of cefepime-induced NCSE presenting as coma in a patient with ESRD on hemodialysis. A 73-year-old man, who had been receiving maintenance hemodialysis, developed aphasia and coma during cefepime therapy for epidural abscess. Emergent eletroencephalography (EEG) revealed evidence of NCSE. The abnormal EEG findings were resolved and comatose mentality was completely recovered after cessation of cefepime and administration of anticonvulsive drugs. Cefepime-induced NCSE should be considered if neurological symptoms including comatose mentality develops during cefepime therapy in a patient with renal failure.
