Pediatric Salmonella enterocolitis in a teaching hospital in Taitung: A four-year analysis.

In order to understand the childhood Salmonella enterocolitis in Taitung, we retrospectively collected the patients with the diagnosis of acute enterocolitis who were admitted to the pediatric wards of Taitung branch of Mackay Memorial Hospital from January 1, 1995 to December 31, 1998. Salmonella enterocolitis accounted for 16.8% of the total cases of acute enterocolitis. The mean age of the patients was 14.6 +/- 14.1 months old. Seventy-nine patients were male and 78 patients were female. Eighty-two patients lived in the urban area and 75 patients lived in the suburbs. The mean duration from onset of illness to admission was 2.6 +/- 1.9 days. The mean duration of hospitalization was 6.6 +/- 4.8 days. The peak incidence was in August and September. The most common clinical manifestations were fever (74.5%) and blood stool (46.5%). In 157 patients, Salmonella serogroup B was isolated from stool in 115 patients. The rate of bacteremia was 4.5%. Serogroup D accounted for 28.6% of the bacteremia. Two patients developed meningitis and one patient had osteomyelitis. Of 88 patients examined for rotavirus, 12 had positive results. There was neither bowel perforation nor mortality recorded in our study.

[Acute necrotizing enterocolitis during a prolonged treatment with neuroleptics].

A 32-year old man treated for several years with phenothiazine for chronic psychosis developed acute necrotizing colitis. The causal relationship with neuroleptics was reinforced by the absence of any other treatment and by histological findings including extensive mucosal necrosis without stenotic lesion and without mesenteric vessels alteration. The patient required emergency total colectomy and was discharged after 7 weeks of hospitalisation in the intensive care unit.

Neutropenic enterocolitis in acute leukemia: diagnostic and therapeutic dilemma.

The main purpose of this report is to focus on the importance of an accurate etiologic diagnosis of gastrointestinal complications during chemotherapy for acute myeloid leukemia, taking into account that a syndrome characterized by bowel wall thickening associated with diarrhea and abdominal pain may have etiologies different from neutropenic enterocolitis (NE) and in such a case necessitate a different treatment approach. We describe a case of a 46-year-old woman affected by acute myeloid leukemia presenting the onset of a syndrome with clinical features of NE. Supportive therapy for NE was instituted, but during treatment the patient presented a life-threatening gastrointestinal bleeding and was submitted in emergency to hemicolectomy. Following surgery, the patient recovered completely and she is currently alive in complete remission after receiving allogeneic bone marrow transplantation. Histological examination of the surgical specimens showed that the acute abdominal syndrome was related to massive infiltration of the bowel by leukemia cells. A correct baseline evaluation and a prompt diagnosis of the complication may help in making the therapeutic decision, which in our case led necessarily to a surgical procedure, because the bleeding was due to post-chemotherapy necrosis of the leukemic infiltrating tissue. A close collaboration between the hematologist and the surgeon may provide guidelines for behavior in such cases, giving these patients the possibility of survival and the opportunity to carry on the treatment planned for the primary disease.

Shigella enterocolitis and acute renal failure.

Although acute renal failure secondary to infections is relatively common in adult patients, uremia requiring dialysis has not previously been reported in an adult patient with shigella enterocolitis. Our patient, infected with S flexneri, had severe renal failure without any evidence of sepsis, rhabdomyolysis, or the hemolytic-uremic syndrome. Antibiotic therapy with trimethoprim-sulfamethoxazole appeared to play a role in his eventual recovery.

[Protective effects of glutamine and elemental diet in acute actinic enterocolitis: histological evaluation].

Radiotherapy plays nowadays an important role in malignancies treatment. However, collateral effects and severe complications owing to cellular damage of peritumoral tissues may occur. Different nutritional resources have been recently indicated to achieve intestinal protection during cancer irradiation. PURPOSE--The aim of this study was to set the role of glutamine and elemental diets in acute actinic enteritis prevention. METHOD--Sixty-five adult male Wistar rats with average weight of 200g were maintained in individual metabolic cages; daily body weight and food ingestion were carefully monitored. The animals were randomized into three groups and fed isocaloric and isonitrogenous diets: 1) CRt-polymeric-casein diet; 2) GRt-polymeric-casein diet supplemented with 2% glutamine and 3) ERt-elemental diet supplemented with 2% glutamine. After an adaptation period (seven days), all rats received abdominal radiation in five daily doses of 300cGy. Four days after the rats were operated on to resect the small intestine and colon for histological evaluation. RESULTS--Small intestine histological data in ERt and GRt rats were better than CRt rats, by preserving mucosal cellularity and increasing mitosis number and villi length. Simultaneously, ERt group had greater number of rats with normal villus-crypt relation than CRt or GRt groups. Large intestine histological data showed that the average crypts length in ERt and GRt rats were greater than in CRt ones. CONCLUSION--Glutamine-supplemented polymeric or elemental diets given to rats before, during and after abdominal radiotherapy showed protective effects against radiation injury, by supporting mucosal structure and recovery.

Neutropenic enterocolitis in acute myeloid leukemia.

In this report we focus on the importance of an accurate diagnosis of gastrointestinal complications during chemotherapy for acute myeloid leukemia. The leukemic infiltrtion of the digestive system may cause mucosal ulcers which can lead to bleeding or perforation. The immune system deficiency in this cohort of patients may result in necrotic enterocolitis (leukemic typhlitis), perianal inflammation, abscesses, and peritonitis. We describe a 37-year old male who presented in June 2004 with 2-month history of fever, weakness and sore throat, treated with antibiotic therapy. Physical examination demonstrated palor. The peripheral blood count at admittance was as follow: Hemoglobin 87 g/l, WBC 63 x 10(9)/l, and platelets 56 x 10(9)/l. The peripheral blood differential count showed: myeloblasts 4%, polymorphonuclear neutrophils (PMN) 20%, monocytes 60%, lymphocytes 16%. The diagnosis of acute myeloid leukemia (AML) was confirmed by bone marrow aspirate, which presented an almost total infiltration by monocytoid blasts, AML type M5 according to FAB classification. Immunophenotypic evaluation by flow cytometry showed that the blast cells reacted with antibodies to CD33, CD13, CD14, CD64, CD15, cytogenetics showed normal karyotype. Induction treatment consisting of cytarabine 2 x 200 mg intravenously in push on days 1-8, vepeside 200 mg i.v. on days 1-5, adriblastine 90 mgon days 1,3 and 5. On day 15 of chemotherapy the patient got fever 38.5 degrees C, abdominal pain and diarrhea (10 stools daily). Broad-spectrum antibiotic therapy with ceftriaxone and amikacin was promptly instituted but condition worsened, abdominal pain extended to all abdomen while the fever and diarrhea persisted. Ultrasonography on day 18 documented bowel wall thickness of colic tract, part of duodenum and jejunum. Owing to suspicion of neutropenic enterocolitis, antibiotic therapy intensified with teicoplanin, fluconazole, metronidazole and pipril. Patient was neutropenic and thrombocytopenic, although daily platelet transfusion from a single donor were given. We started with granulocyte colony stimulating factor (G-CSF) 5 g/kg, which was adiminstered for 7 days. After 7 days neutrophil value reached 1 x 10(9)/l, but fever persisted, abdominal distension and diarrhea progressively improved. The fever peristed and central venous catheter was removed on day 30. After removal of the catheter the patient was getting better: the fever disappeared. The blood count showed Hb 91 g/l, WBC 3,4 x 10(9)/l, platelet 114 x 10(9)/l and normal leukocyte differential count. We emphesize the importance of collaboration between the hematologist and the surgeon in monitoring gastrointestinal complications during and after chemotherapy for acute leukemias and value of abdominal ultrasonography evaluation.

Efficacy and safety of oral cefixime therapy in common infectious diseases in children.

Twenty-nine children, including 20 boys and 9 girls, were enrolled in an open trial of oral cefixime therapy for common pediatric infectious diseases. Patients aged between 0.5 month and 12 years with a mean +/- standard deviation of 2.3 +/- 2.8 years. The diagnoses included 10 of acute otitis media, 2 of purulent rhinitis, 4 of acute enterocolitis, and 13 of urinary tract infection. Most children received 6-12 mg/kg/day of cefixime granules, orally twice daily for more than five days. All 10 cases (100%) of acute otitis media and 2 cases of purulent rhinitis were either cured, or improved by oral cefixime treatment. None of them was microbiologically evaluable. Four cases (100%) of acute enterocolitis, 3 due to Salmonella group B, one due to Shigella flexneri, were also successfully treated with bacteria eradication. However, the cure rate of 13 cases of urinary tract infection was only 85% (11/13). Seven Escherichia coli and 4 Proteus mirabilis infections were eradicated, whereas one each of Enterobacter cloacae and Klebsiella pneumoniae infections did not respond to treatment; these two cases had a complicated course. The overall cure and improvement rate was 93%. Although five patients had transient episodes of mild diarrhea, no significant adverse reaction was observed. In summary, oral cefixime given twice daily was effective and safe in the treatment of a variety of common infectious diseases in pediatric patients.

[Acute necrotizing enterocolitis in an adult--a clinical study].

The authors retrospectively reviewed 24 cases of necrotizing enterocolitis, in which the diagnosis was made or confirmed intraoperatively. This article points to the complex pathophysiology and preoperative diagnostic difficulties of necrotizing enterocolitis due to its clinical heterogeneity and lack of specificity of the laboratory findings. Given all these preoperative problems quite too often the best operatory moment is los and despite the somehow simple intraoperative diagnosis and the modern, well established surgical principles: resection of the necrotic segment with secondary reanastomosis (whenever possible), the post-therapeutic mortality rate remains disappointingly high (70.8%).
