In surgery, deep-seated fungal infection is not rare. In our institute, fungal infection was analyzed during postoperative periods. As pathogen, fungus was the second frequent pathogen after the operations for esophageal cancer and gastric cancer, and the third pathogen after hepatobiliopancreatic cancer and colon cancer. Furthermore, fungus was found more frequently pathogen from distant infection than that from local foci. Especially in CV catheter sepsis, fungus was main pathogen (60 %). In order to inhibit CV catheter sepsis, nutrition support team (NST) has been induced in our institute for prevention of external pathway of fungus. After NST, the frequency of CV catheter sepsis decreased from 12 % to 3.6 %, and the isolated frequency of fungus in catheter sepsis patients also decreased from 84 % to 16 %, respectively. It demonstrates that the activity of NST successfully prevents the external pathway of fungus in CV catheter indwelling patients. However, internal pathway (fungal translocation) still remains, and that issue has to be overcome. Molecular biological technique was applied for diagnosis of fungemia. PCR-RFLPs was performed by using specific primer of 18s rRNA in V4 region. Clinical samples were applied for PCR-RFLPs, and antifungal therapy was performed according as the results of PCR-RFLPs. It indicated that molecular biological technique was useful for diagnosis of fungemia.

A Phase I dose escalation trial of i.v. administered recombinant human interleukin 12 (rhIL-12) was performed to determine its toxicity, maximum tolerated dose (MTD), pharmacokinetics, and biological and potential antineoplastic effects. Cohorts of four to six patients with advanced cancer, Karnofsky performance >/=70%, and normal organ function received escalating doses (3-1000 ng/kg/day) of rhIL-12 (Genetics Institute, Inc.) by bolus i.v. injection once as an inpatient and then, after a 2-week rest period, once daily for five days every 3 weeks as an outpatient. Therapy was withheld for grade 3 toxicity (grade 4 hyperbilirubinemia or neutropenia), and dose escalation was halted if three of six patients experienced a dose-limiting toxicity (DLT). After establishment of the MTD, eight more patients were enrolled to further assess the safety, pharmacokinetics, and immunobiology of this dose. Forty patients were enrolled, including 20 with renal cancer, 12 with melanoma, and 5 with colon cancer; 25 patients had received prior systemic therapy. Common toxicities included fever/chills, fatigue, nausea, vomiting, and headache. Fever was first observed at the 3 ng/kg dose level, typically occurred 8-12 h after rhIL-12 administration, and was incompletely suppressed with nonsteroidal anti-inflammatory drugs. Routine laboratory changes included anemia, neutropenia, lymphopenia, hyperglycemia, thrombocytopenia, and hypoalbuminemia. DLTs included oral stomatitis and liver function test abnormalities, predominantly elevated transaminases, which occurred in three of four patients at the 1000 ng/kg dose level. The 500 ng/kg dose level was determined to be the MTD. This dose, administered by this schedule, was associated with asymptomatic hepatic function test abnormalities in three patients and an onstudy death due to Clostridia perfringens septicemia but was otherwise well tolerated by the 14 patients treated in the dose escalation and safety phases. The T1/2 elimination of rhIL-12 was calculated to be 5.3-9.6 h. Biological effects included dose-dependent increases in circulating IFN-gamma, which exhibited attenuation with subsequent cycles. Serum neopterin rose in a reproducible fashion regardless of dose or cycle. Tumor necrosis factor alpha was not detected by ELISA. One of 40 patients developed a low titer antibody to rhIL-12. Lymphopenia was observed at all dose levels, with recovery occurring within several days of completing treatment without rebound lymphocytosis. There was one partial response (renal cell cancer) and one transient complete response (melanoma), both in previously untreated patients. Four additional patients received all proposed treatment without disease progression. rhIL-12 administered according to this schedule is biologically and clinically active at doses tolerable by most patients in an outpatient setting. Nonetheless, additional Phase I studies examining different schedules and the mechanisms of the specific DLTs are indicated before proceeding to Phase II testing.

Neutropenia is the dose-limiting toxicity of docetaxel in children. This Phase I trial was designed to determine the maximum tolerated dose, the dose-limiting toxicities, and the incidence and severity of other toxicities of docetaxel with filgrastim (G-CSF) support in children with refractory solid tumors. Docetaxel was administered as an i.v. infusion for 1 h every 21 days with a starting dose of 150 mg/m2 and an escalation to 185 mg/m2 and 235 mg/m2 in subsequent patient cohorts. G-CSF (5 microg/kg/day) was administered s.c., starting 48 h after docetaxel and continuing until the post-nadir neutrophil count reached 10,000/microl. Seventeen patients received 27 courses of docetaxel with G-CSF support. Generalized erythematous desquamating skin rash and myalgias were dose-limiting at 235 mg/m2. Localized and generalized rashes were seen at all of the three dose levels. Neutropenia (median nadir, 95/1microl) occurred at all of the dose levels but was brief in duration and not dose-limiting. Thrombocytopenia was minimal (median platelet count nadir, 139,000/microl), and the severity of neutropenia and thrombocytopenia did not seem to be related to the docetaxel dose. Other docetaxel-related toxicities included hemorrhage (associated with mucositis), sepsis, hypersensitivity reaction, transient elevation of liver enzymes, stomatitis, back pain, asthenia, and neuropathy. One minor response was observed in a patient with colon cancer. The maximum tolerated dose of docetaxel with G-CSF support in children is 185 mg/m2, which is 50% higher than the maximum tolerated dose of docetaxel alone in children and 85 % higher than the recommended adult dose.

To determine the clinical usefulness of the autopsy in elderly patients, we studied a total of 231 autopsies performed during 1986 and 1995 at Jikeikai hospital. Autopsies were done after 231 of 609 deaths (38%). The autopsy rate in our hospital fell from 63% in 1986 to 17% in 1995. Most primary causes of deaths as established by clinicians before autopsy were pulmonary, neoplastic, and cardiovascular diseases. The probability of a major unexpected finding at autopsy was higher in acute pneumonia, acute myocardial infarction, and cerebrovascular disease. No primary pathological cause of death was established by pathologists at autopsy in 13 cases (The clinical diagnoses in those patients were acute pneumonia in 5 patients, acute myocardial infarction in 2 patients, sepsis in 2 patients, bronchiale asthma, cerebral infarction, uremia, gastrointestinal bleeding each in 1 patient.) The mean age of these 13 patients was higher by 5 years than the age of the group as a whole. This indicate that elderly patients have many complications and that these deaths were caused by many small changes that were not be detected at autopsy. Latent cancer was found in 23 cases (12%): thyroid and colon cancer in 6 patients each, gastric cancer in 4, prostate cancer in 3, ovarian cancer in 2, and other cancers (renal, uterine, lung, urethral, pancreatis and liver) each 1 in patient.

INTRODUCTION: Mucositis induced by antineoplastic drugs is an important, dose-limiting, and costly side effect of cancer therapy. The ulcerative lesions produced by mucotoxic chemoradiotherapy are painful, restrict oral intake and, importantly, act as sites of secondary infection and portals of entry for the endogenous oral flora. The overall frequency of mucositis varies and is influenced by the patient's diagnosis, age, level of oral health, and type, dose, and frequency of drug administration. Some degree of mucositis occurs in approximately 40% of patients who receive cancer chemotherapy. Approximately one-half of those individuals develop lesions of such severity as to require modification of their cancer treatment and/or parenteral analgesia. The condition's incidence is consistently higher among patients undergoing conditioning therapy for bone marrow/peripheral blood progenitor cell transplantation, continuous infusion therapy for breast and colon cancer, and therapy for tumors of the head and neck associating concomitant chemotherapy and radiotherapy. Among patients in the high-risk protocols, severe mucositis occurs with a frequency in excess of 60%. Concomitant with mucositis is often a chemotherapy-induced myelosuppression. The neutropenia that results puts the patient with oral mucositis at significant risk for systemic infection. Patients with mucositis and neutropenia have a relative risk of septicemia that is greater than four times that of individuals without mucositis. The morbidity of all mucositis can be profound. It is estimated that approximately 15% of patients treated with radical radiotherapy to the oral cavity and oral pharynx will require hospitalization for treatment-related complication. In addition, severe oral mucositis may interfere with the ability to deliver the intended course of therapy, leading to significant interruptions in treatment, and possibly impacting on local tumor control and patient survival. It is also not unusual for mucositis to necessitate delays in cancer chemotherapy particularly with those agents that are known to be mucotoxic, including 5-fluorouracil with or without folinic acid, methotrexate, doxorubicin, etoposide, melphalan, cytosine arabinoside and cyclophosphamide. In addition to its impact on a patient's treatment course, on quality of life, and morbidity and mortality, mucositis can also have a significant economic cost. This is particularly true in the autologous and allogeneic bone marrow transplant settings for hematologic malignancies, where the length of hospital stay may be prolonged due to severe mucositis.

IL-1beta stimulation of cultured epithelial cells induces the degradation of IkappaBalpha and the consequent nuclear translocation of NF-lambdaB, a critical proinflammatory transcription factor in the mucosal host immune response. The role of reactive oxygen intermediates, serine protease activity, and tyrosine kinase activity in the activation of NF-kappaB is weakly conserved across various cell lineages and has not been defined in human enterocytes, a major target of oxidant stress in sepsis, thermal injury, and hemorrhagic shock. We report here that in Caco-2BBe cells, a transformed human colon cancer cell line with features of small intestinal epithelial cells in culture, exposure to oxidant stress (hydrogen peroxide 1-10 mM) did not induce NF-kappaB activation. Similarly, scavenging of free radicals and oxidants by pyrrolidine dithiocarbamate and dimethyl sulfoxide did not block IL-1beta-induced IkappaBalpha degradation and NF-kappaB activation. Genistein, a nonspecific tyrosine kinase inhibitor, also had no effect on IL-1beta-mediated effects on NF-kappaB. Serine protease inhibition by tosyl-lysine-chloromethylketone and tosyl-phenylalanine-chloromethylketone inhibited IkappaBalpha degradation and NF-kappaB activation stimulated by IL-1beta. Our data highlight the strong divergence between epithelial and mononuclear cells in the signal transduction pathways relating IL-1beta stimulation and NF-kappaB nuclear translocation.

Meningitis due to Streptococcus bovis is rare. Only 14 cases having been reported in the English literature. All patients (including the patient described) had an underlying disease or were treated by pharmacological agents that predisposed the patient to the infection. Most were treated by monotherapy with penicillin G (or amoxicillin) and recovered. We describe a 74-year-old woman who had splenectomy as treatment for hairy cell leukemia 6 months before hospitalization for meningitis and sepsis by S. bovis type II. She was successfully treated with intravenous amoxicillin. There was neither evidence of endocarditis nor carcinoma of the colon. Although the association between S. bovis meningitis and endocarditis or carcinoma of the gastrointestinal tract is not well established, we recommend a full work-up for GI malignancy and endocarditis in every patient with S. bovis meningitis.

We report a patient known to have an enterovesical fistula who presented severe acute metabolic acidosis during an episode of urinary retention. The enterovesical fistula which had been intermittently symptomatic for 4 years, had developed after several intestinal surgical procedures and related intraperitoneal sepsis following resection of colon cancer 21 years previously. The patient who had a total colectomy and ileostomy, was admitted for hip replacement with the routine placement of a Foley bladder catheter. Three weeks post-operatively, the patient developed acute urinary retention following removal of the urinary catheter. The output from his ileostomy was immediately markedly increased, presumably from bladder urine diverted into the intestines through the enterovesical fistula. Within a few days he presented a normal anion gap metabolic acidosis with raised urea and stable creatinine; his clinical status deteriorated markedly with profound obtundation. These metabolic abnormalities were readily corrected by re-insertion of the Foley catheter with restoration of normal urine flow and immediate corresponding fall in the ileostomy output. Radiographic studies showed the presence of the enterovesical fistula originating from the jejunum. This is the first report of acute metabolic acidosis in association with an enterovesical fistula; the severe metabolic disturbances were triggered by the development of urinary retention resulting in the diversion of urine into the small bowel through the fistula.

Extra-arterial dislocation of a catheter is one of the complications with hepatic arterial infusion chemotherapy. The authors report a case of sepsis related to catheter tip dislocation to the duodenal bulb. A 69-year-old man underwent sigmoidectomy for sigmoid colon cancer and partial hepatectomy for synchronous metastasis to the liver. We performed hepatic arterial catheterization via the femoral artery, and the patient underwent prophylactic hepatic arterial infusion chemotherapy with 5-FU. Thirty months later, computed tomography during arteriography (CTA) using a port system revealed the dislocation of catheter tip to the duodenal bulb. He showed no symptoms, so we kept him under observation. Sepsis occurred because of the dislocated catheter 39 months later. After removal of the catheter, the symptoms of sepsis disappeared.

Peritoneovenous shunt placement has been reported as a treatment of refractory ascites by general surgeons, but without a clearly established role. The authors successfully inserted shunts under ultrasonographic and fluoroscopic guidance in 12 patients who had symptomatic refractory ascites (nine men, three women; mean maintenance duration, 88.5 d). Nine patients had advanced liver cirrhosis (five with superimposed hepatoma). Other patients had stomach cancer, colon cancer, and complicated polycystic kidney disease. The mortality rate was 83%. Causes of death included bleeding from preexisting varices, sepsis, hepatic failure, rupture of hepatoma, and disseminated intravascular coagulation. The authors describe the feasibility, technical details, and short-term results of percutaneous peritoneovenous shunt placement.
