A Case of Peritonitis Due to Achromobacter xylosoxidans subsp. xylosoxidans in a Patient Undergoing Continuous Ambulatory Peritoneal Dialysis (CAPD) / 대한신장학회지

Bacterial peritonitis is a well-recognized complication of continuous ambulatory peritoneal dialysis (CAPD) in patients with end-stage renal failure. Achromobacter xylosoxidans subsp. xylosoxidans is a catalase and oxidase positive, motile, nonfermentative and gram-negative rod bacterium that is a rare pathogen in humans and has rarely been reported as an opportunistic human pathogen. We present a case of peritonitis due to unusual pathogens, Achromobacter xylosoxidans subsp. xylosoxidans. A 49-year-old diabetic man undergoing CAPD for 90 days developed the first peritonitis due to Achromobacter xylosoxidans subsp. xylosoxidans. A. xylosoxidans was detected from a culture of peritoneal fluid. Susceptible antibiotic treatment was provided.

A Case of Medullary Thyroid Carcinoma in which the Skin Metastasis was Concurrently Present and Response Occurred to Chemotherapy / Journal of the Korean Cancer Association, 대한암학회지

Medullary thyroid carcinoma accounts for 3% of all thyroid gland malignancies. It commonly metastasizes to liver, lung, and bone. It rarely metastasizes to skin, and only a few such cases have been documented. Cutaneous metastasis suggests a poor prognosis, with a mean survival of 7.5-19 months. The most effective treatment for skin metastasis is complete surgical removal of all local and regional lesions. The response to systemic chemotherapy is typically poor. We report a case of medullary thyroid carcinoma with cutaneous metastases, which responded to chemotherapy.

Coincidental Congenital Absence of the Posterior Arch of the Atlas and the Unilateral Lumbosacral Articular Process: A Case Report / 대한정형외과학회잡지

We encountered a case of coincidental congenital complete absence of the posterior arch of the atlas and the unilateral lumbosacral articular process. A 21-year-old man presented with pain in the lower back and right buttock. The patient was a swimming coach. On plain radiography, computerized tomography and magnetic resonance imaging, the congenital absence of the unilateral lumbosacral articular process was noted. Six months later, the patient developed severe neck pain and suboccipital headaches without neurological signs. On plain radiography and computerized tomography, the congenital complete absence of the posterior arch of the atlas was noted. Magnetic resonance imaging showed no abnormal signs originating from the posterior spinal cord. There was no segmental instability. For this case, the lower back pain and neck pain were managed by conservative treatment. To the best of our knowledge, this is the first case of a coincidental congenital complete absence of the posterior arch of the atlas and the unilateral lumbosacral articular process.

A Case of Chronic Active Hepatitis Developed in Patient with Psoriasis after Long-term Methotrexate Treatment / 대한간학회지

Methotrexate (MTX) has been widely used in the treatment of psoriasis and rheumatoid arthritis. But prolonged use of MTX can induce hepatic fibrosis and even cirrhosis. To date, in Korea, there have been very few reports on hepatotoxicity due to MTX, and no report on biopsy-proven chronic active hapatitis. We report one patient who developed chronic acitve hepatitis while taking long-term daily dose of MTX(10mg per day) for psoriasis for a prolonged period.
