Olecranon Osteomyelitis due to Actinomyces meyeri: Report of a Culture-Proven Case / 감염과화학요법

Actinomyces meyeri is a Gram positive, strict anaerobic bacterium, which was first described by Meyer in 1911. Primary actinomycotic osteomyelitis is rare and primarily affects the cervicofacial region, including mandible. We present an unusual case of osteomyelitis of a long bone combined with myoabscess due to A. meyeri. A 70-year-old man was admitted for pain and pus discharge of the right elbow. Twenty-five days before admission, he had hit his elbow against a table. MRI of the elbow showed a partial tear of the distal triceps tendon and myositis. He underwent open debridement and partial bone resection for the osteomyelitis of the olecranon. Biopsy showed no sulfur granules, but acute and chronic osteomyelitis. The excised tissue grew A. meyeri and Peptoniphilus asaccharolyticus. Intravenous ceftriaxone was administered and switched to oral amoxicillin. Infection of the extremities of actinomycosis often poses diagnostic difficulties, but it should not be neglected even when the characteristic pathologic findings are not present.

Wernicke Encephalopathy after Endoscopic Necrosectomy in Acute Necrotizing Pancreatitis with WOPN: A Case Report / 대한췌담도학회지

Infected walled-off pancreatic necrosis (WOPN) is dangerous complication of acute pancreatitis. Open necrosectomy and post-operative irrigation of necrotic cavity have been conventional treatment for infected pancreatic necrosis, however, recently minimally invasive techniques such as endoscopic necrosectomy has been regarded as preferred treatment method for infected WOPN. Endoscopic necrosectomy provides a targeted approach with a reduction in the systemic inflammatory response and avoidance of wound complications. Non alcohol related Wernicke encephalopathy is rare disease caused by thiamine deficiency due to intravenous feeding, and presented an encephalopathy, oculomotor dysfunction, gait ataxia. We report herein a case of Wernicke encephalopathy after successful endoscopic necrosectomy for infected WOPN.

Ramsay Hunt Syndrome in a Patient Infected with Human Immunodeficiency Virus / 대한내과학회지

Ramsay Hunt syndrome is caused by reactivation of the varicella zoster virus in the geniculate ganglion of the sensory branch in the face and ears. It is characterized by peripheral facial palsy, ear pain, and vesicles in the auditory canal and auricle. We report on a first case of Ramsay Hunt syndrome in a patient with human immunodeficiency virus in Korea. The patient, a 40-year-old male, first presented with otalgia and ear fullness. On admission, he had right facial palsy of the peripheral type, otorrhea, headache, limited tongue movement, and right auricle vesicular eruptions. He had positive human immunodeficiency virus antibody and Western blot tests. His CD4 T cell count was 281/microL. The patient was treated with valacyclovir and steroid with highly active antiretroviral therapy. His symptoms and facial palsy improved with treatment.
