The Authors describe a rare case of Yersinia Enterocolitica (Y.E.) infection in a child affected by thalassemia. The onset of the disease was that of an acute enteritis with diarrhea, fever, vomiting and abdominal pain which subsequently evolved in a picture consistent with an acute appendicitis. Laparotomy was then performed and showed a marked suppurative mesenterial lymphadenitis with mild appendicular inflammation and Y.E. infection was suspected. Culture from lymphonodes confirmed the presence of Y.E. sensitive to tobramicin and CTM. The use of these chemiotherapic agents has been followed by a rapid clinical improvement. Our recent experience could suggest some practical considerations: 1) Culture of Y.E. should be routinely performed in all children affected by acute gastroenteritis and particularly in those, above 5 years of age, in which the infection can simulate acute appendicitis. 2) Special attention should be carried out in children affected by thalassemia who can easily present more serious disease often complicated by septicemia. 3) Therapy depends on the form and severity of the disease and should be always guided by in vitro sensitivity test because of the possibility of resistence of Y.E. against the most frequently used antibiotics in septicemia.

49 children younger than 3 years old and treated for acute appendicitis were investigated retrospectively. The symptoms of this age group are general and diarrhea is not uncommon. Examination of the urine including microscopy should always be performed. The white cell count in peripheral blood is of doubtful value in diagnosing acute appendicitis. A roentgenographic examination of the abdomen was helpful in 78% of the patients studied. The correct diagnosis was delayed in 43% of the cases and this extended the observation time by 2.9 +/- 2.4 days. The appendix was perforated in 79%, complications occurred in 18% and there was no mortality. A high degree of alertness seems essential for the early diagnosis of acute appendicitis in this age group.

Pharmacokinetic, bacteriological and clinical studies were performed in pediatrics on tazobactam/piperacillin (TAZ/PIPC), a combined drug of a new beta-lactamase inhibitor tazobactam and piperacillin at a ratio of 1:4. 1. Serum levels and urinary excretions of TAZ, PIPC and desethyl piperacillin (DEt-PIPC), a metabolite of PIPC, after one shot intravenous administration of 50 mg/kg of TAZ/PIPC to two children (6-7 years old) were investigated. The serum TAZ level at 0.08 hour was 50.8-51.0 micrograms/ml after administration. Then TAZ concentrations gradually decreased with half-lives of 0.38-0.45 hour, and reached 1.0-1.4 micrograms/ml after 2 hours and was not detected after 3 hours and 6 hours. Serum PIPC levels at 0.08 hour was 167.0-231.0 micrograms/ml after administration. Then PIPC concentrations gradually decreased with half-lives of 0.41-0.55 hour, and reached 1.2-2.4 micrograms/ml after 3 hours and was not detected after 6 hours. DEt-PIPC was detected slightly in serum. A ratio of TAZ to PIPC was about 1 to 4 in serum at each time. Urinary recovery rates of TAZ in the first 6 hours after administration of TAZ/PIPC were 33.5-90.1% and those of PIPC were 41.9-77.8% and those of DEt-PIPC were 1.5-2.8%. 2. TAZ/PIPC was administered to 27 pediatric patients (their ages ranged between 2 months and 11 years old) with various infections, and clinical and bacteriological effects and adverse reactions were investigated. Single doses were 26.2-55.6 mg/kg, frequencies of administration were 3-4 times a day, and durations of administration were 3 1/3-7 1/3 days, and total dosages were 4.5-33.75 g. Clinical effects were evaluable in 26 cases. Responses were rated as "good" in acute purulent tonsillitis 1 case and acute purulent otitis media 1 case, as "excellent" in acute sinusitis 1 case, as "excellent" in 2 and "good" in 1 out of 3 cases of acute bronchitis, as "excellent" in 13 and "good" 2 out of 15 cases of acute pneumonia, as "excellent" in acute urinary tract infection 2 cases and as "excellent" in acute enteritis in 1 case, acute appendicitis in 1 case and lymphadentis in 1 case. In all cases, the results were rated as "good" or "excellent". Antimicrobial effects against a total of 10 strains identified or assumed to be pathogenic bacteria were evaluated. The 10 strains of bacteria included 4 strains of Streptococcus pneumoniae, 3 strains of Haemophilus influenzae (2 strains beta-lactamase producing), 2 strains of beta-lactamase producing Moraxella catarrhalis, 1 strain of beta-lactamase producing Morganella morganii. All the bacteria listed here were judged to have been eradicated. Adverse reaction was observed in 1 case with mild diarrhea. As abnormal changes in laboratory data, leucocytopenia in 1 case, elevation of GOT. GPT in 2 cases and eosinophilia in 1 case were observed. On the basis of the findings, TAZ/PIPC was considered to be effective and safe in the treatment of pediatric infections.

The assessment and diagnosis of abdominal pain in childhood continues to be a clinical challenge. We audited the presenting symptoms and signs in a consecutive series of 447 children presenting to a paediatric surgical unit in an attempt to quantify the value of particular symptoms and signs in differentiating acute appendicitis (AA) from non-specific abdominal pain (NSAP). The onset of pain in the centre of the abdomen and radiation of pain was not sufficient to differentiate between NSAP and AA. Progression of pain, nausea, vomiting, anorexia and diarrhoea were significantly more common in children with AA (P < 0.01). Similarly, facial flushing, tachycardia (pulse > 100 beats/min), guarding and rebound tenderness were significantly more common in children with AA (P < 0.001). Knowledge of this quantitative data could help clinicians adjust the weighting given to the presence of a particular symptom or sign in children with acute abdominal pain.

A case of a young male operated on for acute appendicitis due to a carcinoid of the base is reported. Since the tumor was infiltrating the resection margin of the appendix, the patient was later treated with a right hemicolectomy. Carcinoid tumor is unusual, but can be encountered several times during the career of a surgeon (1/200-300 appendicectomy). The tumor is more frequent in women (2-4:1), located at the tip of the appendix (62-78%) and has a diameter less than 1 cm in 70-95% of cases. It is more frequently diagnosed incidentally after an operation for acute appendicitis and occasionally during other procedures (colectomy, cholecystectomy, salpingectomy). Liver metastases are rare (< 2%), related to the dimension of the primitive tumor (21-100% when > 2 cm) and can cause a "carcinoid syndrome": flush, diarrhea bronchoconstriction, cardiac valve disease. Diagnosis is made by the pathologist and staging by conventional radiologic procedures (TAC, US), dosage of neuroendocrine mediators such as 24 hours urinary 5-HIAA. Nowadays 111In-octreotide scintigraphy (SRS) has an 86% sensitivity to detect the carcinoid and is useful for staging and for planning a surgical intervention. Simple appendectomy is adequate treatment for appendiceal carcinoids less than 1 cm in diameter. Adequate treatment for tumors greater than 2 cm is right hemicolectomy. A point of controversy is what to do for tumors in the 1 to 2 cm range. It seems that appendectomy alone is sufficient except in those cases when mesoappendiceal invasion is identified. When surgical margins after appendectomy are not free of tumor, additional surgery seems warranted. Carcinoid tumor of the appendix has a good prognosis with a 5-year-survival rate, of 85.9-100%. When liver metastases are encountered octreotide can relieve symptoms and sometimes the progression of the disease.

By 1996, the median survival of patients with cystic fibrosis (CF) in North America had increased to 31 years. With the markedly improved life expectancy, many CF patients are now adults. There is an associated increased risk of certain colonic disorders, and the emergence of other previously unrecognized disorders, in adult CF patients. The distal intestinal obstruction syndrome (DIOS), which is more common in older patients, is a frequent cause of abdominal pain. Intussusception may complicate DIOS; other differential diagnoses include appendiceal disease, volvolus, Crohn's disease, fibrosing colonopathy and colonic carcinoma. The diagnosis of acute appendicitis, although uncommon in patients with CF, is often delayed, and appendiceal abscess is a frequent complication. The prevalence of Crohn's disease in CF has been shown to be 17 times that of the general population. Right-sided microscopic colitis is a recently recognized entity in CF of uncertain clinical significance. Fibrosing colonopathy has been confined mostly to children with CF, attributed to the use of high strength pancreatic enzyme supplements, but it has been reported in three adults. Nine cases of carcinoma of the large intestine have been reported worldwide, associated with an apparent excess risk of digestive tract cancers in CF. Despite high carrier rates of Clostridium difficile in patients with CF, pseudomembranous colitis is distinctly rare, but severe cases complicated by toxic megacolon have been reported. In these patients, watery diarrhea is often absent. Adult CF patients with refractory or unexplained intestinal symptoms merit thorough investigations.

A 12-year-old girl presented with lower abdominal pain, nonbilious vomiting, and a severe secretory diarrhea. Infectious and noninfectious etiologies were ruled out, and she was found to have perforated acute appendicitis. It is essential to consider acute appendicitis in the differential diagnosis for secretory diarrhea and abdominal pain in the pediatric population.

Dientamoeba fragilis is a non-enteroinvasive, protozoan parasite of the human large intestine with a worldwide prevalence. Considered for years to be a non-pathogenic organism, more recent studies suggest that up to 25% of adult hosts and up to 90% of infested children may manifest clinical disease. D. fragilis infestation has been implicated in chronic gastrointestinal syndromes characterized by protean complaints such as post-prandial abdominal pain, chronic diarrhea, flatulence, fatigue, anorexia, and weight loss. Rarely, D. fragilis infestation is the etiology of acute abdominal pain, mimicking a surgical abdomen. A case report is presented that details a patient with a 1-month history of vague abdominal complaints who presented to the Emergency Department with an apparent episode of acute appendicitis.

The clinical picture of regional enteritis was reviewed in 98 cases collected from five hospitals in the City of Edmonton. There was no apparent racial prevalence, although only one case was reported among Indians and Eskimos. More than one-half had their onset between the ages of 11 and 30 years. Men were more commonly affected than women. The onset in 44 patients was acute and closely mimicked acute appendicitis. Twenty-eight patients had had abdominal surgery prior to the onset of symptoms. Major symptoms were abdominal pain, diarrhea and weight loss. Abdominal tenderness, fever and abdominal mass were the most consistent physical signs. The most valuable diagnostic procedure was radiological examination of the bowel. Complications were largely confined to the gastrointestinal tract. In the majority of cases, surgery was the ultimate form of therapy.
