A statistical analysis was undertaken of 1158 children admitted to a surgical ward for the management of acute abdominal pain. Over two-thirds (40%) of the children had non-specific abdominal pain while 29.7% had appendicitis. The remainder were found to have had urinary tract infections (11.7%), constipation (7.5%), gastroenteritis (5.8%) or intussusception (5.3%). A stepwise discriminant analysis of the data collected during their evaluation was performed, using the BMDP statistical software package. Demographic and clinical features, as well as the results of ancillary investigations, were included in the data. The programme generated a classification function of a sub-set of 18 variables which best discriminated among the diagnostic groups. The coefficients of the classification functions were then combined with the rank order of selection of the variables to derive a scoring method for predicting the diagnosis. The results of urine culture were excluded since these would be unavailable during early clinical assessment. The scores for the diagnostic groups fell within the following ranges:-1-23 Non-specific abdominal pain; 20-48 appendicitis; 35-84 Gastroenteritis; 75-88 Constipation and 89-140 Intussusception. It is suggested that this scoring method be evaluated by a prospective study to test its validity.

Many patients with acquired immune deficiency syndrome (AIDS) and abdominal pain are evaluated by the surgeon, and the majority have gastroenteritis, which can be treated with specific antimicrobials. There are some, however, who need more extensive investigation or who have an intra-abdominal infective process that requires surgical treatment. The one and a half decades of experience with human immunodeficiency virus (HIV) and AIDS has defined the role of the surgeon in treating patients with HIV. Major infective processes that may require surgical involvement include cytomegalovirus infection of the intestinal tract; appendicitis, which may be due to opportunistic infections; spontaneous bacterial peritonitis; cholecystitis; and obstructive jaundice with underlying sclerosis of the biliary tree. Early diagnosis and prompt surgical treatment are critical in the management of HIV-infected patients. For example, cytomegalovirus affecting the gastrointestinal tract may lead to perforation with the development of generalized fecal peritonitis; the clinical presentation of acute appendicitis in HIV patients may not include the usual rise in white blood cell count; and bacterial peritonitis in patients with AIDS may be caused by opportunistic pathogens or, as in the classical case, a single gram-negative bacillus or pneumococcus. This review article focuses on intra-abdominal infections in patients with HIV and AIDS.

A retrospective case series was conducted at a teaching hospital with an emergency department (ED) census of 100,000 patients per year to identify the incidence of, and factors associated with, the misdiagnosis of appendicitis in nonpregnant women aged 15 to 45 years. There were 174 nonpregnant women identified with a pathologic diagnosis of appendicitis. Clinical features were then compared between patients misdiagnosed (seen in prior 10 days and given an incorrect diagnosis) and those who were initially diagnosed correctly. The results showed that 33% of the women with appendicitis were initially misdiagnosed. The most common misdiagnoses included pelvic inflammatory disease, gastroenteritis, and urinary infections. Misdiagnosed women more frequently exhibited diffuse and bilateral lower abdominal pain and tenderness, cervical motion, and right adnexal tenderness. Misdiagnosed women also had a lower incidence of right lower quadrant pain and tenderness, and peritoneal signs. In addition, misdiagnosis was associated with an increased incidence of perforation, abscess formation, and an increase in the total length of hospitalization. In conclusion, the incidence of misdiagnosis of appendicitis in women of childbearing age is high. Women who are misdiagnosed have less typical symptoms and physical findings and more frequent abnormal pelvic findings than those who are diagnosed correctly. Emergency physicians should be aware that atypical signs and symptoms are associated with misdiagnosed appendicitis in nonpregnant women of childbearing age.

In this case-control study, we investigated the role of Cryptosporidium in gastroenteritis in children < 6 years old. Six hundred fresh stool specimens were examined for various pathogenic parasites, bacteria, and rotaviruses. Wet-mount preparations, formaline-ether concentrations, and Sheather's floatation techniques were used to recover the parasite oocysts. Permanent stained slides using acid-fast stain and trichrome stains were prepared. Of 300 children with gastroenteritis symptoms, 20 (6.7%) had Cryptosporidium oocysts; seven of the 20 had concomitant infections so they were excluded from the counts. This infection rate is significantly different (Z = 2; p < 0.05) from that found in the control group (1.7%) of children who reported no symptoms. The most frequent symptoms reported beside diarrhea were abdominal pain, cramps, anorexia, nausea, vomiting, and fatigue. Contaminated drinking water is suspected to be the source of infection; other possible factors are discussed.

In a paediatric surgical practice over a 10 year period, 59 children presenting with left sided abdominal pain, acute or chronic, were investigated and followed up to identify the cause. Only two were found to have an identifiable surgically significant cause, one being hydronephrosis and the other being congenital uterine abnormality. Other causes suspected were Mittelschmerz, faecal retention or gastroenteritis, functional, abdominal migraine and allergy. Two boys developed torsion of the testis within 2 years of an episode of left sided abdominal pain. This is considered significant and the examination of boys with left sided abdominal pain should include careful scrutiny of the testis and assessment of its disposition with the boy standing. In both sexes investigation should focus initially on the urinary tract.

To identify differences between correctly diagnosed appendicitis and misdiagnosed cases that resulted in litigation between 1982 and 1989 retrospective review of malpractice claims was conducted. A total of emergency department (ED) charts at the time of the initial ED visit were reviewed and compared with 66 concurrent controls. Missed cases appeared less acutely ill, had fewer complaints of right lower quadrant pain, received fewer rectal examinations, received intramuscular (IM) narcotic pain medication for undiagnosed abdominal pain or symptoms, and more often received an ED discharge diagnosis of gastroenteritis. Misdiagnosed patients had a 91% incidence of ruptured appendix, more extensive surgical procedures, and more postoperative complications. Data were analyzed using the Pearson's chi 2 Test, Mann-Whitney U Test, and stepwise discriminant analysis. Significance was defined as P < or = .05. Misdiagnosis of acute appendicitis is more likely to occur with patients who present atypically, are not thoroughly examined (as indexed by documentation of a rectal examination), are given IM narcotic pain medication and then discharged from the ED, are diagnosed as having gastroenteritis (despite the absence of the typical diagnostic criteria), and with patients who do not receive appropriate discharge or follow-up instructions.

Non-typhoid salmonellosis remains a common infective illness. We studied 77 consecutively admitted children aged 1 month to 15 years in order to determine frequency of antecedents, the strain of the isolated organisms, clinical findings, frequency of complications and the adequacy of management. The presentation and severity of the illness were compared between younger than two and older children. Salmonella typhimurium was isolated in 65% of the cases. Two thirds of the tested strains were multiresistant to antibiotics. Non-typhoid salmonellosis usually occurred in the form of acute gastroenteritis: in only 4% of the cases it presented as pyrexia of unknown origin without gastrointestinal symptoms. 30% of the cases had been exposed to one or more antimicrobial agents within four weeks before the date of their stool culture. Only 30% had been breast fed. Previously diagnosed cow's milk protein intolerance resulted to be present in 14% of the less than two years old children (p < 0.02). Abdominal pain and headache were found more frequently in older children (p < 0.02). Protein C reactive values were significantly higher in this age group (p < 0.05). 25% of the children were mildly or moderately dehydrated. Hypernatremia was uncommon. 31% of the cases were treated with antibiotics: the antimicrobial treated children presented diarrhoea for longer period (p < 0.05) and they remained admitted for longer time (p < 0.00).(ABSTRACT TRUNCATED AT 250 WORDS)

We report the clinical characteristics of three adult patients with a chronic gastroenteritis (more than 10 days duration) due to Plesiomonas shigelloides. The three patients presented previously an underlying disease; a chronic liver disease (alcoholic and viral) and a cancer disease. Although the immunosuppressed condition of the patients, the diarrhea was moderate with 6-12 movements/day; the feces were liquid with mucose and blood. No one patient presented fever but all of them had important abdominal pain. Two patients were treated with cotrimoxazole and ciprofloxacin because of their underlying disease. We review the clinical characteristics of chronic diarrhea caused by P. shigelloides in adult patients, and the possibility that this microorganism would be considered a true enteropathogen.

Blastocystis hominis is now gaining acceptance as an agent of human intestinal disease. A case-control study of the cause of gastroenteritis in children less than 6 years old was conducted. A total of 500 stool specimens were examined by wet mount preparation, formalin-ether concentration, Sheather's sugar flotation technique, and permanent stains when necessary. B. hominis was found in 63 (25%) of 250 stool specimens of the cases examined; 38 (15%) of these specimens contained this parasite alone. The appearance of severe symptoms was associated with increased numbers of the parasite in the diarrheic specimens (more than five parasites per field at a magnification of x 400). The most common symptoms were abdominal pain, recurrent diarrhea, cramps, anorexia, and fatigue. Contaminated water was suspected to be the major source of infection, since several cases were associated with Giardia infection. These findings support the concept of B. hominis pathogenicity in children with gastroenteritis.

The purpose of this study is to evaluate the prevalence of free peritoneal fluid in children with abdominal pain, identify conditions associated with this finding, and determine the ability of ultrasonography to detect associated abnormalities. Two hundred and fifty children with acute abdominal pain and a reference group of 50 asymptomatic children were evaluated for the presence of free peritoneal fluid. Free peritoneal fluid was noted in 72 (29%) symptomatic and three (6%) asymptomatic children. A specific diagnosis was established in 39 (54%) symptomatic children. The discharge diagnosis in the remaining 33 (46%) children was abdominal pain or gastroenteritis of unknown origin. Ultrasonography suggested the correct diagnosis in 29 out of 39 (74%) symptomatic children in whom a specific diagnosis was established at the time of discharge from the hospital. The presence of free peritoneal fluid detected by an ultrasonographic examination in children who have abdominal pain represents a nonspecific finding. Fluid is noted in association with a variety of abdominal and pelvic disorders. In approximately one half of symptomatic children with free peritoneal fluid, the final diagnosis is abdominal pain or gastroenteritis of unknown etiology. In the remainder, ultrasonography aids in the determination of a specific diagnosis.
