&NA;A 41‐year‐old black woman with a history of well‐controlled, insulin‐dependent diabetes mellitus was in her usual state of relatively good health when she had acute onset of right upper quadrant and epigastric abdominal pain, nausea, and vomiting. Physical examination and laboratory evaluation revealed gastrointestinal hemorrhage, decreased mental status, and acidemia, and emergency exploratory laparotomy elucidated ischemic bowel, of which 90 cm was resected. Postoperatively, the patient had cardiac arrest and could not be resuscitated. Autopsy was remarkable for mesenteric venous thrombosis and pylethrombosis, with ischemic necrosis of bowel and passive hyperemia. The arterial side of the cardiovascular system was relatively unaffected. Although arterial vascular complications of diabetes mellitus are well known, venous complications are less well described.

摘要:

&NA;Major congenital anomalies occur in approximately 4% of the newborn population. Although this risk is apparently the same for in vitro fertilization (IVF) pregnancies, couples having assisted reproduction therapy should receive appropriate genetic counseling, because coincidental maloccurrences are often erroneously linked to the technology. We report a case of newborn esophageal atresia with tracheoesophageal fistula occurring in an IVF pregnancy. Physicians are encouraged to educate all prospective parents regarding the rate of congenital anomalies in the general population so that they have realistic expectations concerning newborn outcome.

摘要:

&NA;Carbohydrate antigen 19‐9 (CA 19‐9) has been used as a serum tumor marker for adenocarcinoma of the upper gastrointestinal tract, particularly primary adenocarcinoma of the pancreas. This tumor marker has also been used to differentiate benign from malignant diseases of the pancreas. However, significant elevations of CA 19‐9 levels in the absence of pancreatic malignancy have also been reported. This case illustrates a marked elevation of CA 19‐9 due to an infectious process in a patient with a pancreatic mass suggestive of malignancy.

摘要:

&NA;Acquired amegakaryocytic thrombocytopenia is a rare disorder characterized by severe thrombocytopenia and selective, marked decrease or absence of megakaryocytes. Although immunosuppressive therapy (prednisone and/or antithymocyte globulin) has been shown to induce remissions in a subset of patients, most patients do not respond, and progression to aplastic anemia occurs in some cases. We report a case of acquired amegakaryocytic thrombocytopenia which, despite aggressive immunosuppressive treatment, rapidly progressed to aplastic anemia. Clinical, laboratory, and immunologic features of our patient's case are described and compared to those of the previously reported six cases that progressed from amegakaryocytic thrombocytopenia to aplastic anemia.
