An elderly woman with an acute abdomen due to a perforated peptic ulcer is discussed to illustrate the problem of atypical presentation of illness in the elderly. The importance of not dismissing non-specific symptoms and signs such as confusion, restlessness, abdominal distention and non-localising abdominal tenderness in the elderly, is highlighted. In addition, the useful radiological features of pneumoperitoneum are described. The need for functional assessment and rehabilitation are emphasised as important components in the practice of geriatric medicine.

The appendicitis is the commonest cause of an acute abdomen in children older 1 year of age. Only 5% of children with appendicitis are younger than 2 years of age. There is a familial preponderance. The younger the child the faster the symptoms of the disease are increasing in intensity. The symptoms starts with unspecific periumbilical or epigastric pain, followed by nausea, vomiting and restlessness at night. Finally the pain moves to the position of the appendix. The position of the appendix shows a high variation in children thus the pain characteristic is not uniform. Laboratory tests are not reliable but ultrasonography is recommended to exclude other diseases and to try to confirm the diagnoses. With the technique of "Graded compression Sonography" the rate of non identified appendicitis has been reduced under 5%. Laparoscopy is another option. Its use just for diagnostic purposes is limited but is recommended widely for primary therapeutic treatment with laparoscopic performed appendectomy. Laparoscopy has a special advantage against conventional appendectomy in the diagnostic of recurrent unspecific abdominal pain in children and in cases with interval appendectomy. Finally in pseudoappendicitis and pseudoperitonitis in children with immunvasculitis and other extraabdominal diseases. Letality of the acute appendicitis is zero.

Visceral pain is caused by either distension or contraction of the visceral muscular wall or obstruction of hollow gastrointestinal organs. Unlike the somatic pain due to peritonitis, visceral pain is diffuse, epigastric, periumbilical and is often accompanied by nausea, vomiting and restlessness. We demonstrate the significance of visceral pain in the differential diagnosis of the acute abdomen presenting five cases of appendicitis and cholecystitis. A correct early diagnosis of the acute abdomen while signs of local peritonitis are still absent (appendicitis in atypical location, recurrent acute appendicitis, spontaneous reopening of an occlusion) is facilitated by the awareness for the characteristics and symptoms of visceral pain, and therefore careful taking of the patient's history. A history lacking visceral pain on the other hand represents an important clue for the diagnosis of other conditions (gynecological, diverticulititis, etc.) with acute pelvic peritonitis.

Bowel problems occur in 27% to 62% of patients with spinal cord injuries (SCI), most commonly constipation, distention, abdominal pain, rectal bleeding, hemorrhoids, bowel accidents, and autonomic hyperreflexia. The acute abdomen, with a mortality of 9.5%, does not present with rigidity or absent bowel sounds but rather with dull/poorly-localized pain, vomiting, or restlessness, with tenderness, fever, and leukocytosis in up to 50% of patients. Fecal impaction may present with anorexia and nausea. Methods used for bowel care include laxatives, anal massage, manual evacuation, and enemas. Randomized, double-blind studies demonstrated the effectiveness of neostigmine, which increases cholinergic tone, combined with glycopyrrolate, an anticholinergic agent with minimal activity in the colon that reduces extracolonic side-effects. Improved bowel function occurs with anterior sacral root stimulators which may be combined with an S2 to S4 posterior sacral rhizotomy which interrupts the reflex arc by cutting the posterior roots carrying the spasticity-causing sensory nerves. For severe constipation, a colostomy reduces time for bowel care, providing a clean environment so decubitus ulcers may heal. Gallstones occur in 17% to 31% of patients, and acalculous cholecystitis in 3.7% of patients with acute SCI. A high index of suspicion is needed to properly diagnose bowel problems in SCI.
