In a controlled, prospective study the following five criteria were used for the diagnosis and management of acute appendicitis: abdominal pain; vomiting; right lower quadrant tenderness; low grade fever (< or = 38.8 degrees C); and polymorphonuclear leucocytosis (TC > or = 10,000 with polymorphs > or = 75%). The aim of the study was to reduce the negative appendicectomy rate. If four out of five or five out of five criteria were present on admission, appendicectomy was carried out. On the other hand, if three out of five criteria were present on admission, the patient was subjected to active inpatient observation until either the development of the fourth criterion, when appendicectomy was performed, or until the patient recovered and the condition did not progress beyond the third criterion. Generalised peritonitis due to a perforated appendix was excluded from the study. Over a 1-year period, 58 patients (M:F = 45:13) were entered into the study. Appendicectomy was carried out in 46 (80%) of patients; of these, 32 patients (70%) were operated on soon after admission. The remaining 14 (30%) were operated on after a period of inpatient observation decided the development of the fourth criterion. A total of 12 patients (12/58 = 20%) did not undergo operation. The control group consisted of 59 patients upon whom appendicectomy was carried out by another surgical unit over the same 1-year period. The negative appendicectomy rate in the trial group was 6.5% (3/46), whereas in the control group it was 17% (10/59) (P < 0.05). We conclude that the use of a simple scoring system can significantly reduce the negative appendicectomy rate.

The diagnosis of acute appendicitis can be difficult. Barium enemas, computed tomography (CT) scans, ultrasound examinations and Indium scans are used to aid in making the diagnosis with varying degrees of success. This blinded, prospective study reports the use of a Technetium 99-m Hexamethylpropyleneamineoxide (HMPAO) labelled white blood cell scan in 30 patients with suspected appendicitis. Autologous white blood counts from 25 cc of whole blood labelled with Tc-99 HMPAO were reinjected into patients. Abdominal imaging was performed at a half hour postinjection and repeated at 2 to 4 hours postinjection. A positive study showed an increased isotope uptake in the right lower quadrant. Nineteen patients had histologically proven appendicitis. Three of these patients were excluded because they were operated on before scan completion. Thirteen of the remaining 16 patients with appendicitis had positive studies (false negative rate = 19%). All patients without appendicitis had either negative scans or scans that detected other intra-abdominal diseases, such as diverticulitis, tubo-ovarian abscess, or small bowel infarction (false positive rate = 0%). Overall, this Tc-99 HMPAO study had a sensitivity of 81 per cent, a specificity of 100 per cent and an overall accuracy of 89 per cent. The 4-hour Tc-99 HMPAO WBC scan is a useful, noninvasive test for confirming the clinical diagnosis of acute appendicitis, but it may prove more valuable as a diagnostic study to rule out appendicitis in patients that have abdominal pain of unclear etiology.

A 45 year old man with personal history of B-Lactamic antibiotics allergy and one episode of hemochezia was admitted to hospital because of abdominal pain in the lower right quadrant and nausea, and diagnosed of acute appendicitis. At laparotomy he was found to have histological evidence of transmural eosinophilic enteritis in the terminal ileon and ascitis. After an intestinal resection a full evaluation was performed.

Of 6,099 children treated for malignancy, 16 (ages 3.5 to 18 years) developed acute appendicitis between 1962 and 1989. Fourteen had leukemia (ALL 10, AML 4). One each had rhabdomyosarcoma and Ewing's sarcoma. Active malignancy at diagnosis was noted in 10, 4 of whom had severe neutropenia (absolute neutrophil count less than 500/mm3). Of all the leukemics (2,794/6,099), abdominal pain during induction was a frequent complaint. The incidence of appendicitis, however, was low (0.5%). Nine of the 16 patients presented classically, facilitating prompt diagnosis and treatment. Six diagnoses were delayed. Three of these patients presented atypically with vague, nonlocalized pain, abdominal distention, lack of abdominal guarding, fever, dehydration, diarrhea, and unusual symptoms such as upper gastrointestinal bleeding. In each of these 6 patients the appendix was ruptured. Delays led to complications and deaths. Three patients required perioperative transfusions to treat excessive bleeding and two patients with ruptured appendicitis developed wound abscesses. Two patients died; in one, ruptured appendix was diagnosed only at autopsy. The other patient died of uncontrolled sepsis. Typhlitis occurring during induction chemotherapy may present similarly and is the main differential diagnosis. Typhlitis will usually improve with medical treatment alone. Nausea and vomiting (13/16), right lower quadrant pain (13/16), guarding (14/16), tachycardia (12/16), fever (10/16), and rebound tenderness (10/16) were the most frequent signs and symptoms of appendicitis. Persistent localized abdominal pain and guarding, lack of improvement with medical treatment, clinical deterioration, and the development of a mass were our indications for laparotomy. Despite major improvements in therapy, there is still a 37.5% error rate in our ability to accurately diagnose appendicitis in pediatric cancer patients.

108 consecutive patients presenting with suspected acute appendicitis were studied prospectively. To improve clinical performance, 19 clinical criteria were evaluated. For cases with unclear diagnostic situations laparoscopy was performed. With 10 of the above mentioned criteria the score published by de Dombal, which can reach a maximal value of 7 points, was calculated. For data processing the rate of negative appendectomies as well as the de Dombal score were used. 61 appendectomies with 7 (11.5%) perforations, 48 (78.7%) acute inflammations and 6 (9.8%) normal appendices have been performed. 39 (36.1%) patients with non-specific abdominal pain were observed for 3 +/- 2 days before discharge, while 7 (11.5%) had another surgical disease. In the appendectomized patients the score was 4.3 +/- 1.1 with perforation, 4.4 +/- 1.0 with acute inflammation and 3.8 +/- 1.3 with a normal appendix (p = ns). The score for non-specific abdominal pain in patients not undergoing surgery was significantly lower (2.2 +/- 1.2; p less than 0.01). Patients with other surgical diseases had a score of 3.1 +/- 1.1 with no significant difference from patients who had undergone appendectomy or from those with non-specific abdominal pain. Laparoscopy was performed in 16 (14.8%) patients. 9 patients had appendicitis, 4 non-specific abdominal pain and 3 another surgical disease. Improved clinical examination significantly (p less than 0.05) reduced negative appendectomies from 20.3% to 9.8% without a rise in the rate of perforation due to prolonged observation. The 6 patients with negative appendectomy could not be identified even by improved clinical examination.

An 8-year-old girl presented with the clinical features of acute appendicitis. The removed appendix was normal but the abdominal pain persisted. There were no urinary symptoms and bacteriological examination of the urine was negative. An ultrasound scan showed an intravesical tumor that was subsequently excised. Histology showed a grade 1 transitional cell papillary bladder carcinoma of low grade malignancy. All previously reported cases have presented with urinary tract symptoms, usually hematuria.

Primary pneumococcal peritonitis is an uncommon condition 1st identified in 1885. It occurs when peritoneal inflammation is present in the absence of an intraabdominal source of infection. In the preantibiotic era, the condition accounted for 2% of childhood abdominal emergencies largely among girls aged 2-10 years. Mortality was 42-100%, with death sometimes occurring within 48 hours of the onset of symptoms. This condition now present in female adults, is associated with IUD use, and is comparatively common in India. Consideration should therefore be given to the existence of primary pneumococcal peritonitis when diagnosing and managing abdominal emergencies. The pneumococcus may enter the peritoneal cavity via the female genital tract, blood, or through transmural spread from the gastrointestinal tract. No evidence supports a relationship between type of IUD and/or length of time in place, and the onset of peritonitis. Given pneumococcus' commensal existence in the upper respiratory tract, urogenital sex may facilitate its entrance to the peritoneal cavity through the female genital tract. Abdominal pain, diarrhea, and vomiting generally present, while the patient may also be pyrexial and dehydrated. In diagnosing this condition, the practitioner may confuse it with acute appendicitis, pelvic inflammatory disease, or gastroenteritis if in the early stages of peritonitis. Diagnosis is often confirmed only thorough laparotomy, but abdominal paracentesis and/or abdominal ultrasound may also be employed as diagnostic aids. Laparotomy and a regime of antibiotics is the preferred treatment. 2 case studies are discussed.

In this series, nine pregnant patients had appendectomy. Seven patients had acute appendicitis; pyuria and symptoms suggesting urinary tract infection delayed diagnosis in one whose appendix perforated. Abdominal pain and nausea with or without vomiting were presenting symptoms in all of the patients. Tenderness in the right lower quadrant was present in six. Eight patients, including two with a normal appendix, had leukocytosis with a left shift. There was no fetal or maternal loss. In addition, I reviewed more than 900 other cases of appendectomy during pregnancy, as reported in the literature since 1960. Among 713 previously reported cases of confirmed appendicitis, rupture had occurred in 25%. There were five maternal deaths, all in the group of patients with perforation. Perinatal mortality was 4.8% among patients with acute inflammation only and 19.4% in those with perforative appendicitis. The diagnosis rests on clinical acumen, and prompt surgical intervention is the key to good outcome.

The results of prospectively determined scoring system for the diagnosis of appendicitis (sex, age, duration of symptoms, contracture, hyperleucocytosis) are reported. Between 1984 and 1989, 492 patients with suspected appendicitis were examined. Among the 208 operated patients, 169 had acute appendicitis (81.25 percent). Diagnosis of the abdominal pain was established in one of 3 patients without appendicitis (105/323; non operated patients or operated patients with normal appendix). Eighty-five percent of the non operated patients and 92 percent of the patients operated on with normal appendix have been followed (mean follow-up 26 months). Ten percent of the non operated patients (24/237) have been operated on during follow up; 13.9 percent of the operated patients with normal appendix (5/36) and 22.8 percent of the non operated patients (54/237) still complained of persistent right lower quadrant pain (no significative difference). In conclusion, a clinical scoring system is of help in suspected acute appendicitis. This attitude requires the cooperation of the general practitioner and must be well explained to families of patients.

Between 1982 and 1989, 78 children with diarrhoea-associated haemolytic uraemic syndrome (HUS) were referred to this hospital. Most presented with abdominal pain, bloody diarrhoea and vomiting. Seven had severe gastrointestinal involvement, four of whom required resection for bowel perforation or necrosis. One also developed an oesophageal stricture, a previously unreported complication of HUS. These seven children had a high incidence of other complications including hypertension, and cerebral and pancreatic involvement. One died from severe cerebral involvement, one has a residual neurological deficit and one has residual renal impairment. Severe gastrointestinal involvement did not significantly affect the long-term outcome. Simple haematological indices helped predict severe gut involvement. Four of the 78 children had undergone appendicectomy before the diagnosis of HUS was made. The operative findings were in no case typical of primary acute appendicitis, although histological examination did confirm inflammation of the appendix in two patients. Diagnosis is difficult in early disease, but increased awareness may help prevent unnecessary appendicectomy.
