MAPS: a microarray project system for gene expression experiment information and data validation.

SUMMARY: MAPS is a MicroArray Project System for management and interpretation of microarray gene expression experiment information and data. Microarray project information is organized to track experiments and results that are: (1) validated by performing analysis on stored replicate gene expression data; and (2) queried according to the biological classifications of genes deposited on microarray chips.

A pancreatic intraductal papillary mucinous tumor causing recurrent acute pancreatitis at the onset of menstrual periods.

The unusual case of a young woman with pancreatitis recurring at onset of her menstrual periods is reported. The patient was diagnosed with pancreatic intraductal papillary mucinous tumor (IPMT). The temporal relation of clinical exacerbation of pancreatitis to the menstrual cycle is suggestive of a hormonal-mediated mechanism. The hypothesis of a possible role of progesterone receptors was dismissed with verification of the absence of progesterone and estrogen receptors in the neoplastic tissue. The possible role of activin A or inhibin A in our patient's clinical picture is theorized.

A case report of ascariasis of the common bile duct in a patient who had undergone cholecystectomy.

This is a case report of ascariasis of the common bile duct in a 65-year-old man from Colombia who had undergone prior cholecystectomy. The patient presented with postprandial epigastric pain and a 20-lb weight loss. The laboratory findings were remarkable for peripheral blood eosinophilia. The ultrasound finding was suggestive of periampullary or pancreatic neoplasm. He underwent endoscopic retrograde cholangiopancreatography with endoscopic extraction of a motile, live worm identified as Ascaris lumbricoides. Roundworm infestation should always be suspected in immigrants from endemic areas who present with hepatobiliary symptoms.

Posttransplantation lymphoproliferative disorder in the knee.

Lymphoproliferative disorders with primary presentation in a joint are extremely rare. Posttransplantation lymphoproliferative disorders are commonly extranodal at presentation but rarely involve joint structures. The authors describe a fatal case of posttransplantation lymphoproliferative disorder presenting in the knee of a 39-year-old woman who had undergone renal transplantation many years before.
