A 58 year old Chinese male, one week after arriving in Canada from Hong Kong, presented with
acute abdominal pain
and diarrhoea which was rapidly followed by Escherichia coli infection causing septicaemia and meningitis. His past history revealed bronchial asthma for 15 years treated with steroids. At laparotomy, 7 days after the onset of symptoms, he was found to have extensive haemorrhagic infarction of the small bowel and right colon. Examination of the fibrosed mesenteric vessels revealed numerous filariform larvae of Strongyloides stercoralis, within the walls, and in all layers of bowel wall. The role of the parasite in the production of obliterative arteritis in this fatal case of haemorrhagic enteropathy is discussed. Clinical strongyloidiasis, in uncomplicated cases, varies from mild to severe with
gastroenteritis
, nausea, colicky abdominal pain, electrolyte imbalance and symptoms of malabsorption syndrome (MARCIAL-ROJAS, 1971). In malnourished individuals and patients with debilitating infections, either newly acquired or asymptomatic latent infection with S. stercoralis can assume severe dimensions (BROWN and PERNA, 1958; HUGHTON and HORN, 1959). Similarly, in patients on steroid (CRUZ et al., 1966; WILLIS and MWOKOLO, 1966; NEEFE et al., 1973) and immunosuppressive therapy for lymphomatous diseases or deficient in immune response (ROGERS and NELSON, 1966; RIVERA et al., 1970), systemic strongyloidiasis is often fatal. The increased frequency of auto-infection in such patients with a breached immune barrier is, however, unclear. Further complications of this infection due to severe enterocolitis result in sepsis, bacteraemia and meningitis (BROWN and PERNA, 1958; HUGHTON and HORN, 1959). This paper presents a fatal case of S. stercoralis infection which illustrates an uncommon if not unique, mechanism in its production of haemorrhagic enteropathy leading to sepsis and death.

Acute abdominal pain
(AAP) is one of the most frequent causes of admission to an emergency department of a childrens' hospital. The diagnosis viewed with the most apprehension is acute appendicitis. We present the results of a prospective study on the evaluation of the clinical and paraclinical symptoms generally observed in an AAP, and discuss the benefit of a diagnostic score for acute appendicitis. Twenty-five different diagnoses were observed, the 5 most frequent being: "non specific" (34.2%), constipation (16%), otorhinolaryngological infection (11.6%),
gastroenteritis
(10.7%) and acute appendicitis (10.5%). The study of 12 symptoms showed an elevated sensitivity for each one (92-50%), but a low positive predictive value (72-12%). Rigid adhesion to a diagnostic score would have led to unnecessary medical examination.

An epidemic of
gastroenteritis
in a teaching hospital affected 57 patients and 69 staff over a 26-day period. The index case was a patient admitted with
acute abdominal pain
and diarrhea two days prior to the outbreak. The epidemic curve indicated person-to-person transmission. The incubation period, duration and types of symptoms were typical of Norwalk gastroenteritis, and Norwalk-like virus particles, serologically different from the prototype Norwalk virus strain, were observed in 17 of 20 fecal specimens examined by immune-electron microscopy.

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.

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.

The purpose of this study was to determine the frequency with which general pediatricians perform a rectal examination on children with a complaint of
acute abdominal pain
and to determine factors associated with performing a rectal examination. Children were eligible for the study if they were 2 to 12 years of age and presented to the clinic or emergency department of a municipal teaching hospital with a complaint of abdominal pain of less than or equal to three days' duration. Measured variables included demographic characteristics and presenting signs and symptoms. For each patient, a clinical reviewer (1) assigned a final diagnosis, (2) determined whether a rectal examination had been performed, and (3) assessed the clinical contribution of the rectal examination findings. For 1,140 children presenting for a nonscheduled visit with
acute abdominal pain
, a rectal examination was performed on 4.9% (56/1,140). Using multiple logistic regression, children were more likely to have a rectal examination performed if they had abdominal tenderness (odds ratio [OR] = 3.3 and 95% confidence interval [CI], 1.8 to 6.0), a history of constipation (OR = 6.0 and 95% CI, 2.3 to 15.3), or a history of rectal bleeding (OR = 9.1 and 95% CI, 2.9 to 29). Children were less likely to have had a rectal examination performed if they presented with associated symptoms of cough (OR = 0.32 and 95% CI, 0.14 to 0.74), headache (OR = 0.15 and 95% CI, 0.05 to 0.46), or sore throat (OR = 0.28 and 95% CI, 0.08 to 0.91). The final diagnoses of 12 children who had clinically contributory findings on rectal examination included: constipation (5),
gastroenteritis
(3), appendicitis (2), abdominal adhesions (1), and abdominal pain of unclear etiology (1). General pediatricians infrequently perform a rectal examination on children who present with a complaint of
acute abdominal pain
. Clinical factors affect the likelihood of whether a rectal examination is performed.

Abdominal pain is among the most frequent ailments reported in the office setting and can account for up to 40% of ailments in the ambulatory practice. Also, it is in the top three symptoms of patients presenting to emergency departments (ED) and accounts for 5-10% of all ED primary presenting ailments. There are several common sources for
acute abdominal pain
and many for subacute and chronic abdominal pain. This article explores the history-taking, initial evaluation, and examination of the patient presenting with
acute abdominal pain
. The goal of this article is to help differentiate one source of pain from another. Discussion of acute cholecystitis, pancreatitis, appendicitis, ectopic pregnancy, diverticulitis, gastritis, and
gastroenteritis
are undertaken. Additionally, there is discussion of common laboratory studies, diagnostic studies, and treatment of the patient with the above entities.

In evaluating the accuracy of diagnostic tests there are many situations where the true disease status can be one of multiple disorders. For example, when paediatric patients suffer
acute abdominal pain
, the underlying diagnosis could be appendicitis, intestinal obstruction,
gastroenteritis
, urinary tract infection, etc. In this paper we describe a format for collecting data for the case of multiple truth states. This new format allows one to make pairwise comparisons of the diagnostic accuracy between all of the different truth states. We propose a summary measure of accuracy which is a weighted average of the pairwise estimates of accuracy. Estimators are derived for the variance and covariance of the estimated summary accuracy. The small sample properties of the estimators are evaluated in a Monte Carlo simulation study. The new data collection format and summary measure were used in a paediatric
acute abdominal pain
study; data from this study are used to illustrate the methods.

Acute abdominal pain
in children presents a diagnostic dilemma. Although many cases of
acute abdominal pain
are benign, some require rapid diagnosis and treatment to minimize morbidity. Numerous disorders can cause abdominal pain. The most common medical cause is
gastroenteritis
, and the most common surgical cause is appendicitis. In most instances, abdominal pain can be diagnosed through the history and physical examination. Age is a key factor in evaluating the cause; the incidence and symptoms of different conditions vary greatly over the pediatric age spectrum. In the acute surgical abdomen, pain generally precedes vomiting, while the reverse is true in medical conditions. Diarrhea often is associated with
gastroenteritis
or food poisoning. Appendicitis should be suspected in any child with pain in the right lower quadrant. Signs that suggest an acute surgical abdomen include involuntary guarding or rigidity, marked abdominal distention, marked abdominal tenderness, and rebound abdominal tenderness. If the diagnosis is not clear after the initial evaluation, repeated physical examination by the same physician often is useful. Selected imaging studies also might be helpful. Surgical consultation is necessary if a surgical cause is suspected or the cause is not obvious after a thorough evaluation.

Throughout the 1960s and 1970s, pigbel (enteritis necroticans) was the most common cause of death in children over the age of 1 year in hospitals in the highlands of Papua New Guinea (PNG). There has been recent widespread perception that after the successful vaccination program in the 1980s the disease virtually disappeared. A new vaccine is now available, but disease burden information is conflicting: despite almost no pigbel being reported from major hospitals there have been many reports of the disease from outlying health centres. This study aimed to provide information on the disease burden of pigbel in PNG, so that appropriate vaccine policy decisions could be made. We conducted a 12-month prospective study of all cases of acute abdomen in children presenting to 38 health facilities, 29 health centres and 9 hospitals in the highlands. Children were eligible for inclusion if they were aged 1-12 years and had abdominal pain of less than 2 weeks' duration. A standardized case definition of pigbel was used to distinguish cases of
acute abdominal pain
very likely to be due to pigbel from cases very likely to be accounted for by other diagnoses (such as
gastroenteritis
, typhoid, dysentery, intussusception, urinary tract infection and others). A total of 119 cases of acute abdomen were reported from 17 of the 38 health facilities involved. Of these 119 cases 11 met the criteria for pigbel and a further 8 were probable cases. There were 4 deaths among the 119 children with acute abdomen: 2 from definite pigbel, 1 from probable pigbel and the other due to complications of measles. In 2002 pigbel was the cause of between 9% and 16% of presentations with
acute abdominal pain
in children in the PNG highlands. The overall disease burden of pigbel was relatively small (19 definite or probable cases and 3 deaths in 12 months). However, there was substantial geographical clustering of cases: more than 50% of the definite cases occurred in children living within three electorates on the Western Highlands-Enga provincial border, no more than 40 km from each other. This study will be useful in planning pigbel vaccine policy and future surveillance.
