A 29-year-old woman presented to the emergency department with exhaustion, fatigue, and abdominal pain. She reported having received a diagnosis of bulimia nervosa 10 years before. On examination, she had a marked pallor and was severely malnourished. Laboratory analysis revealed a dramatically low hemoglobin level of 1.7 g/dL (ref: 11.5-15.8 g/dL). Serum iron was quantified as 1.4 micromol/L (ref: 7-26 micromol/L), ferritin as 5 ng/mL (ref: 10-120 ng/mL), and the level of serum transferrin as 212 mg/dL (ref: 200-360 mg/dL). A duodenal biopsy revealed villous atrophy in the mucosal layer indicative for celiac disease. This diagnosis was confirmed by serum levels of endomysial antibodies, tissue transglutaminase antibody, and antigliadin antibodies. The newly diagnosed gluten-sensitive enteropathy is likely to be in part responsible for the severe symptoms reported. The extent of hemoglobin decline in combination with an astonishing lack of critical symptoms seen in this patient is a rarity. We conclude that anorectic patients with severe anemia and malnutrition should be evaluated for the presence of additional somatic conditions.

Acute splenic sequestration crisis (ASSC) is a potentially life-threatening complication and one of the leading causes of death in children with sickle cell disease. It is rarely reported in adults with hemoglobin S-C disease and its natural history in these patients has not been well studied. We describe here the clinicopathological features of ASSC in nine adults with hemoglobin S-C disease treated between 1972 and 2000 and followed for a mean period of 9 years (range 0-21 years). ASSC was characterized by acute left upper quadrant abdominal pain, splenomegaly, fever, and a rapid decrease in hematocrit with active erythropoiesis. The hemoglobin decreased by a mean of 4.8 g/dl from the steady state value (range 3.0 to 6.7 g/dl) during ASSC. Two patients failed to respond to transfusion of packed erythrocytes and required urgent splenectomy. There was one fatality-a 76-year-old woman, who died 36 h after admission. There was no recurrence of ASSC in five patients followed for 2, 3, 16, 18, and 21 years, respectively. ASSC in adults is a serious and occasionally, fatal complication of hemoglobin S-C disease. Patients with hemoglobin S-C disease may remain at risk of ASSC into their eighth decade.

The antibiotics, metronidazole and ciprofloxacin, are the first-line treatment for pouchitis. Patients who do not respond to antibiotics or conventional medications represent a major challenge to therapy. In this report, we have described a successful treatment of severe refractory pouchitis with a novel agent, rebamipide, known to promote epithelial cell regeneration and angiogenesis. A 27-year-old male with ileo-anal pouch surgery presented with worsening anal pain, diarrhea, and abdominal pain. The patient was diagnosed to have pouchitis and was given metronidazole together with betamethasone enema (3.95 mg/dose). However, despite this intensive therapy, the patient did not improve. On endoscopy, ulceration and inflammation were seen in the ileal pouch together with contact bleeding and mucous discharge. The patient was treated with rebamipide enema (150 mg/dose) twice a day for 8 wk without additional drug therapy. Two weeks after the rebamipide therapy, stool frequency started to decrease and fecal hemoglobin became negative at the 4th wk. At the end of the therapy, endoscopy revealed that ulcers in the ileal pouch had healed with no obvious inflammation. The effect of rebamipide enema was dramatic and was maintained throughout the 11-mo follow-up. The patient continued to be in remission. No adverse effects were observed during the treatment or the follow-up period. The sustained response seen in this case with severe and refractory pouchitis indicates that agents, which promote epithelial cell growth, angiogenesis and mucosal tissue regeneration, are potential therapeutic agents for the treatment of refractory colorectal lesions.

Chronic constipation that is unresponsive to laxative treatment is a severe illness, but children unresponsive to laxatives have been successfully treated with an elimination diet. We report the first cases of refractory chronic constipation caused by food hypersensitivity in adults. Four patients with refractory constipation who were unresponsive to high doses of laxatives were put on an oligo-antigenic diet and underwent successive double-blind, placebo-controlled, food challenges (DBPFC). Routine laboratory tests, immunological assays, colonoscopy, esophago-gastroduodenoscopy and rectal and duodenal histology were performed. While on an elimination diet, bowel habits normalized in all patients and a DBPFC challenge triggered the reappearance of constipation. In comparison with another 13 patients with refractory constipation unresponsive to the elimination diet, observed over the same period, the patients with food-hypersensitivity-related constipation had the following characteristics: longer duration of illness (p < 0.03), lower body mass index (p < 0.03), higher frequency of self-reported food intolerance (p < 0.01), higher frequency of nocturnal abdominal pain and anal itching (p < 0.01). In patients with food hypersensitivity, hemoglobin concentrations and peripheral leukocytes were lower than those in controls (p < 0.03). The duodenal and rectal mucosa histology showed lymphocyte and eosinophil infiltration, and the duodenal villi were flattened in two cases. In adult patients, refractory chronic constipation may be caused by food hypersensitivity and an elimination diet is effective in these subjects.

Only scarce data are available on chronic copper poisoning in general toxicology literature. This paper reports four patients with chronic copper poisoning and one patient with acute poisoning. The cases with chronic poisoning in our study consisted of four members of a farmer family presenting to the emergency department (ED) with malaise, weakness, abdominal pain, headache, dizziness, tightness in the chest, leg and back pain, accompanied by significant anemia (hemoglobin [Hb]: 8.7 - 9.5 g/dl). They were hospitalized and investigated thoroughly, although there were no other findings or clues enlightening the etiology of anemia. The anemia was attributed to chronic copper exposure acquired from vegetables containing copper. The diagnosis was established by ruling out other possible etiologies and history coupled with laboratory findings. The patients were discharged with the recommendation on diet to avoid consumption of pesticide-treated vegetables. Their Hb values were between 10 and 11.4 g/dl on the 15th day, and between 12 and 14 g/dl after two months. Their symptoms had also resolved completely in two months. The patient with acute intoxication (5th case) had ingested copper oxychloride with suicidal intent. He was admitted with anuria and hemolytic anemia. After being hospitalized for fifteen days, he was diagnosed with chronic renal failure and was scheduled for a dialysis program. Acute poisoning is more deliberate, while chronic exposure may result in atypical findings. In conclusion, physicians working in primary care and EDs should consider copper poisoning in patients presenting with anemia, abdominal pain, headache, tightness in the chest, and leg and back pain.

Hepatic adenomas are benign liver tumors found mostly in young women with a history of oral contraceptive usage. They commonly present with abdominal pain from the tumor mass effect, bleeding, or rupture. We report a case of a young woman with a giant hepatic adenoma presenting with chronic iron deficiency anemia, requiring repeated blood transfusion. The mass was an incidental finding with typical features of a hepatic adenoma. Resection was performed and the hemoglobin remained stable up to the present fourth year of follow-up. This is an unusual presentation for which an association is investigated here. There was no evidence of intra-tumoral bleed but reverse-transcribed real-time PCR revealed higher tumor hepcidin RNA expression. Chronic iron deficiency anemia can be an initial presenting problem in patients with hepatic adenomas. Its cause may be multifactorial but the role of hepcidin-mediated anemia needs further evaluation in future cases.

We report the case of a 48-year-old man with neurofibromatosis presenting with sudden-onset abdominal pain, profound hypotension, and a drop in hemoglobin. CT scan demonstrated a massive hematoma within the right lobe of the liver with rupture into the peritoneal cavity. Angiography demonstrated diffuse abnormalities of the hepatic circulation with fusifom, ectatic, and stenotic segments. Acute extravasation from a peripheral branch of the right hepatic artery was identified and successfully embolized with subsequent hemodynamic stabilization of the patient. To the best of our knowledge this is the first case report of this kind in a patient with type I neurofibromatosis.

Renal medullary carcinoma (RMC) is an aggressive neoplasm occurring almost exclusively in adolescents and young adults with sickle cell (SC) hemoglobinopathies, usually sickle cell trait (SCT) or hemoglobin SC disease. The most common presentations are hematuria and flank or abdominal pain. It is a highly malignant tumor, and responses to chemotherapy are rare and transient resulting in a dismal prognosis. A high level of suspicion is necessary when evaluating at risk patients presenting with hematuria or flank pain, as currently it appears that only early diagnosis could potentially alter the outcome of this disease. We report a case of RMC in a young male patient with SCT, who presented to the emergency department with low back pain and microscopic hematuria, clinically mimicking acute obstructing urolithiasis. Our case emphasizes the need to consider alternate diagnoses when evaluating computed tomography scans for acute flank pain.

Perivascular epithelioid cell tumor (PEComa) is defined as a very rare mesenchymal tumor of histologically and immuno-histochemically distinctive perivascular epithelioid cells. PEComa in the colon is very rare, with only a few reported cases so far. Because of its rarity, the clinical features and biological behavior of PEComa in the colon have yet to be established. A 16-year-old female patient with PEComa in the transverse colon was referred to our hospital for rectal bleeding. Laboratory data showed a hemoglobin level of 6.6 g/dL, WBC of 8,800/mm(3), and platelet count of 191,000/mm(3). Colonoscopy, barium enema, and abdominal computed tomography revealed a 2-cm, smooth-surfaced, round tumor with focal ulceration in the proximal transverse colon. The patient complained of abdominal pain one day after endoscopic polypectomy. She underwent a segmental resection for a perforated transverse colon. Immunohistochemically, the tumor cells showed strong diffuse positivity for HMB-45 while they were negative for c-kit, smooth muscle actin, cytokeratin, S-100, vimentin, desmin, chromogranin, synaptophysin, EMA, and CD-34. The diagnosis of PEComa was based on histological and immunohistochemical staining. The patient did not receive any adjuvant therapy and was discharged on postoperative day 11 without complications. Whole-body fluorine-18 fluorodeoxyglucose fusion positron emission tomography performed 2 months after surgery showed no signs of recurrence or metastasis. There was also no recurrence or metastasis at 24 months' follow-up.

We describe the first patient with hereditary spherocytosis (HS) known to have developed splenic infarction following infectious mononucleosis (IM). An 18-year-old Japanese man was referred to our hospital in November 2004 because of continuous fever and icterus. He had undergone cholecystectomy at the age of 14 years. On patient admission in November 2004, a physical examination showed marked hepatosplenomegaly, icterus, and jaundice. He had a white blood cell count of 14.9 x 10(9)/L with 9.5% atypical lymphocytes, a red blood cell count of 2.93 x 10(12)/L, and a hemoglobin concentration of 7.8 g/dL. Microspherocytes were observed in the patient's peripheral blood smear, and immunoglobulin M antibody to Epstein-Barr virus (EBV) viral capsid antigen was detected. The patient's diagnosis was HS with IM. On day 4 of admission, the patient complained of severe abdominal pain. Abdominal computed tomography scanning revealed findings of splenic infarction. Two months after the occurrence of splenic infarction, a splenectomy was performed. A pathohistologic examination of the resected spleen revealed no evidence of thrombosis or arterial occlusion. We assume that the cause of splenic infarction was insufficient blood flow to oxygenate the entire spleen during the acute enlargement of the spleen.
