Hypercalcemia is a well-known manifestation of paraneoplastic syndromes associated with a variety of malignancies. However, colon cancer has only rarely been associated with hypercalcemia of malignancy. We present the case of a patient with recurrent adenosquamous carcinoma of the ascending colon found to have hypercalcemia. The patient is a 76-year-old white woman who initially presented with colon cancer in the cecum and underwent a right hemicolectomy. All lymph nodes and surgical margins were free of tumor. Pathological examination at that time revealed adenosquamous carcinoma of the colon. Eight months later she complained of dizziness, anorexia, and constipation and was found to have a calcium level of 13.6 mg/dL. CT scan revealed a mass measuring 10.5 to 12.7 cm in the right hepatic lobe, and a bone scan was normal. Her intact parathyroid hormone (PTH) level was 6 pg/mL (normal 12-72) and her PTH-related protein (PTHrP) level was 25.7 pmol/L (normal <1.3). She then underwent a hepatic resection. The serum PTH, calcium, and PTHrP levels normalized after resection. Hypercalcemia of malignancy in colon cancer is rare and has an association with adenosquamous histology. The hypercalcemia is attributed to PTHrP, and here we demonstrate this in the serum and tumor specimens. The effects of PTHrP are shown to be short-lived postoperatively. We find only 14 other cases in the literature of hypercalcemia related to a colonic neoplasm, and this is the only patient reported to be surviving. The diagnosis of a paraneoplastic syndrome mediated via PTHrP should be considered when hypercalcemia is encountered in the setting of metastatic colon carcinoma.

This is the first clinical report of a case of pneumonia caused by Nocardia nova in Japan. A 52 year-old woman who had received steroids and cyclophosphamide for six years because of polymyositis was admitted to our hospital for further examination. On admission she had a mild cough, and her chest radiography and computed tomography revealed bilateral multiple nodules, some of which were cavitated. She developed a cough productive of yellow sputum and fever up to 38 degrees C. Examination of the sputum revealed a gram-positive branched organism and sputum cultures repeatedly grew Nocardia species. The isolate was identified as Nocardia nova later. Clinical recovery was obtained readily upon treatment with imipenem and trimethoprim methoxazole, though the latter drug was discontinued because of nausea and anorexia. This drug was therefore replaced with oral minocycline, which proved to be ineffective clinically although susceptibility testing of the drug showed positive sensitivity. Minocycline was replaced with clarithromycin, after which chest radiography and computed tomography showed almost total resolution of the infiltrates. Clarithromycin may be an alternative oral agent to sulfonamides or minocycline when these agents are ineffective or not tolerated.

A 76-year-old female had been followed in our hospital for dissecting aneurysm, cardiac failure, and cerebral infarction. Inguinal lymphadenopathy, anorexia, and weight loss were noted in June 1998. The histopathologic diagnosis of the biopsied lymph node was diffuse pleomorphic type non-Hodgkin's lymphoma with T-cellular phenotype, and the patient was referred to our department. She had human T-lymphotropic virus type I seropositivity, and PCR of the pX lesion disclosed a monoclonal band. She was ultimately diagnosed as having adult T-cell leukemia/lymphoma (ATL/L, stage IV). Since she had many severe complications, she was given low-dose etoposide (LD-ETP, 50 mg/day). Atypical cells disappeared from the blood, and lymphadenopathy regressed. No major adverse reaction was observed after LD-ETP. She continued to receive intermittent LD-ETP, but she developed pneumonia in June 2000, and died in August 2000. Autopsy disclosed no residual lymphomatous lesions. These findings suggest that LD-ETP is a well tolerable and effective treatment in patients with ATL/L even if there are severe complications.

Castleman's disease is a rare B-cell lymphoproliferative disorder of unknown etiology. In this report we describe a 54-year-old woman with a 10-year history of asymptomatic bilateral, multiple cervical lymph node enlargements. She was not evaluated by lymph node biopsy during this period. She had been well until four months previously. The patient presented with multiple enlarged lymph nodes and systemic symptoms including fever, sweats, weight loss, and anorexia. Two lymph nodes were biopsied, yielding a diagnosis of multicentric Castleman's disease (MCCD) of mixed hyaline-vascular and plasma cell type histology. Serologic studies revealed the simultaneous presence of an acute Epstein-Barr virus (EBV) infection. She experienced an aggressive clinical course with a fatal outcome.

A 26-year-old Thai woman who has lived in Hong Kong for the past 3 years presented with a 2-month history of feverishness, intermittent epigastric discomfort, anorexia, and weight loss. She had had per rectal bleeding for 10 days. Colonoscopy on two separate occasions revealed multiple ulcerations involving the entire colon, with rectal sparing. Histological examination of the two sets of colonic biopsies that were obtained during colonoscopy suggested Crohn's disease. There was no response to mesalazine and metronidazole, but the patient responded promptly to a therapeutic trial of antituberculous drugs. Cultures from the first set of colonic biopsies were negative for acid-fast bacilli, but 8 weeks after the second colonoscopy, cultures from the second set of biopsies yielded Mycobacterium tuberculosis. This case illustrates that the diagnosis of colonic tuberculosis requires a high index of suspicion. In cases where the information available does not reveal a definite differentiation between colonic tuberculosis and Crohn's disease, corticosteroids should be withheld. The administration of corticosteroids to a patient with colonic tuberculosis may have disastrous results, and a therapeutic trial of antituberculous drugs should be considered instead.

We report a case of myeloid/NK cell precursor acute leukemia, which was successfully treated with allogeneic peripheral blood stem cell transplantation (allo PBSCT). A 31-year-old woman was admitted to our hospital with general fatigue, anorexia and leukocytosis. Bone marrow aspiration showed infiltration of many atypical blasts. She was diagnosed as having myeloid/NK cell precursor acute leukemia by morphological and immunohistochemical analysis. Complete remission was achieved by induction chemotherapy, but as myeloid/NK cell precursor acute leukemia is reported to have an extremely poor prognosis due to frequent relapse, the patient underwent allo PBSCT from her HLA-identical father, together with a myeloablative conditioning regimen. She suffered several transplantation-related complications including acute graft versus host disease (grade II) and ischemic enterocolitis associated with thrombotic microangiopathy, but these were overcome by supportive therapy. She was discharged on day 168 after allo PBSCT, and so far there has been no evidence of relapse during a follow-up period of 15 months.

Acute liver disease was diagnosed in three pregnant patients: two 30-year-old women had a 'haemolysis, elevated liver enzymes, low platelets' (HELLP) syndrome and acute fatty liver of pregnancy, respectively, and a 20-year-old woman had acute liver failure due to acute hepatitis B. The first two patients had a caesarean section, the third one delivered her child, which died spontaneously shortly after birth at a gestational age of 23 weeks. She was then treated by liver transplantation. All three patients left the hospital in good condition. Liver diseases in pregnancy may be pregnancy-related, e.g. the HELLP syndrome and acute fatty liver of pregnancy, but they may also be coincidental phenomena, e.g. viral hepatitis. The HELLP syndrome is often associated with pre-eclampsia, and presents with epigastric pain and thrombocytopenia with haemolysis. Acute fatty liver disease and acute liver failure due to hepatitis present with liver insufficiency characterised by anorexia, nausea, coagulopathy, hypoglycaemia and elevated serum ammonia levels. Management depends on the diagnosis and the gestational age; pregnancy complicated by acute fatty liver disease should be terminated while pregnancy complicated by the HELLP syndrome early in pregnancy may be maintained to improve the outcome of the foetus. In acute liver failure due to viral hepatitis, termination of pregnancy alone does not affect the disease.

The patient was a 55-year-old woman who had unresectable advanced gastric cancer with celiac lymph node metastases and invasion of pancreas. The lesions were considered surgically incurable, so she was placed on neoadjuvant chemotherapy consisting of TS-1 and low-dose CDDP, for a total of 3 courses of TS-1 (100 mg/day, 12 weeks) and 2 courses of low-dose CDDP (10 mg/day, 100 mg). The only side effect of this chemotherapy was light anorexia, and the patient maintained a good QOL. After chemotherapy, the tumor had decreased partially in size, but there was little change in the abdominal lymph node metastases. She was considered to have little response and underwent palliative distal gastrectomy, because of the incomplete dissection of abdominal lymph node metastases. After the operation, she was treated with 2 courses of TS-1 100 mg/day (3 weeks administration and 2 weeks rest) and CDDP 70 mg or 50 mg/body (day 8). She had grade 3 anorexia. After discharge, she was treated by combined therapy of TS-1 100 mg/day (2 weeks administration and 2 weeks rest) and TXL 60 mg/body (day 1, 8, 15). After 2 courses of TS-1/TXL therapy, the abdominal lymph node metastases had decreased in size and the tumor markers were reduced remarkably: CEA 146.1-->26.9 ng/ml, and CA19-9,351.5-->210.6 U/ml. The patient received 5 courses of TS-1/TXL therapy, and she had no trouble with side effects. She maintained a good QOL. TS-1/TXL therapy was associated with few adverse events in hospital visits, and thought to be an effective adjuvant chemotherapy against advanced gastric cancer.

A 5-year-old female developed, after a 7-month period of fever, anorexia, weight loss, and a transitory cutaneous erythematous eruption, a severe acute transverse myelopathy, with a partial recovery of motor and sensory function. She had positive antinuclear and antidouble-stranded DNA antibodies but no antiphospholipid antibodies. Six months later she had massive proteinuria and restarted treatment with steroids and cyclophosphamide. Our patient is one of the youngest reported with lupus myelopathy. We discuss the clinical presentation, the magnetic resonance imaging findings, and other relevant laboratory studies of this rare but serious complication of systemic lupus erythematosus.

A 52-year-old woman was admitted because of epigastralgia, anorexia and recently increased vomiting, 2 years after silastic ring vertical gastroplasty. On gastroscopy, a tumor mass was visualized in the pouch near the "neo-pylorus". Biopsies confirmed adenocarcinoma. She underwent total gastrectomy, and has no evidence of recurrence at 1 year. The literature on gastric carcinoma after gastroplasty is reviewed.
