22 cases of primary involvement of the appendix in Crohn's disease are reported in the literature. During the last 3 years we observed 4 cases. In three patients typical clinical signs of acute appendicitis were present. One case was found occasionally. The follow-up was 5-30 months. During this time none of our patients showed symptoms of granulomatous enterocolitis in other regions of the bowel. Reviewing the literature 3 of 26 patients (11.5%) showed lesions typical for Crohn's disease elsewhere in the intestine 3-48 months after appendectomy. But two cases had a follow-up of 5 years which time is considered indispensable before one can admit that the disease is really limited to the appendix.

Amebic abscess of the liver has protean manifestations that often resemble causes of an acute surgical abdomen. Patients presenting at University of California, Los Angeles Hospital with acute abdominal injuries who underwent exploratory laparotomy and subsequently were found to have an amebic hepatic abscess were studied. There are various clinical symptoms of amebic hepatic abscess as well as problems of differentiating this pathologic entity from an acute surgical abdomen. Most patients with amebic hepatic abscess that mimics an acute abdomen present as acute cholecystitis or acute appendicitis. All patients recovered uneventfully once the diagnosis was made and appropriate therapy instituted. The salient features of the history, physical examination and laboratory data that can identify the amebic abscess were analyzed. The key to correct diagnosis is cognizance of the condition.

A 42-year-old Thai man from central Thailand came to Ramathibodi Hospital with the complaint of abdominal pain. Physical examination revealed localized tenderness in the right lower quadrant. The clinical impression was acute appendicitis and an operation was performed, revealing a large mass in the cecum. A right hemicolectomy was done for what was thought to be a carcinoma of the colon. The resected colon showed subserosal thickening on the antimesenteric side of the ascending colon with a constricted area at the middle portion. An immature adult Gnathostoma spinigerum was identified in the thickened subserosa of the cecum. Microscopic examination of the involved bowel showed a heavy infiltration of eosinophils, fibroblasts and histiocytes, and mild to moderate edema. The findings were consistent with eosinophilic granuloma of the gastrointestinal tract, and the presence of the parasite in the affected bowel suggested that it was the etiologic agent.

Acute appendicitis is a well known clinical entity, but many physicians are unwilling to accept appendicitis as a chronic or recurrent illness. Of 225 patients undergoing appendectomy, sixteen (7 per cent) had findings suggestive of chronic, recurrent, or subacute appendicitis. Four patients had chronic abdominal pain and histologic findings of chronic inflammation. Nine patients had previous episodes similar to that which resulted in appendectomy. All had acute suppurative appendicitis pathologically. Three patients had only one episode of abdominal pain, but had pathologic evidence of subacute inflammation. Because this study was retrospective, we suspect that the true incidence of recurrent appendicitis is significantly greater, as reported by others. Indications for operation must be strict, for unless there are specific signs and symptoms of appendiceal disease, appendectomy will often be of no benefit.

It is possible to estimate the category and volume of lost liquid in patients who have become acutely depleted of body fluids by measuring the haematocrit and plasma protein concentration in venous blood samples. Three recent examples of different categories of loss are presented: plasma loss in pancreatitis, extracellular fluid (saline) loss in paralytic ileus, and mixed plasma and extracellular fluid loss in peritonitis complicating acute appendicitis. Goood clinical results were achieved by infusion of appropriate volumes of either plasma or saline so as to restore the haematocrit and plasma protein concentration to their presumptive basal values.

The gas-filled appendix is an uncommon roentgenographic sign that has been considered to be virtually diagnostic of acute appendicitis when the appendix is positioned caudad to the cecum in the right lower quadrant of the abdomen. Three patients had gas in the appendix in the absence of acute appendicitis. This diagnostic sign is therefore not specific for appendicitis. Regardless of its location, the appendix may contain gas despite the absence of intrinsic disease.

The cases of five children with acute leukemia complicated by appendicitis were reviewed. All but one child had typical signs and symptoms of acute appendicitis, though four children were receiving prednisone. All five children underwent appendectomy, and all survived the immediate postoperative period. One child had a spontaneous remission following appendectomy. Two of three children in relapse suffered serious postoperative complications. Our experience supports the surgical management of appendicitis in acute leukemia.

Two cases are reported of Crohn's disease localized to the appendix and manifested as acute appendicitis; after appendectomy a fistula developed. In none of 18 patients with Crohn's disease reported by other authors, where the appendix was the primary site, did a fistula develop postoperatively. When the appendix is the primary site of Crohn's disease the presence of mild inflammation of adjacent organs such as the terminal ileum may be mistakenly attributed to ordinary appendicitis. If, at exploratory laparotomy performed on a tentative diagnosis of appendicitis, Crohn's disease is suspected in the adjacent intestine, it is proposed that appendectomy should be followed by at least 10 days of total parenteral nutrition to minimize the risk of a fistula developing.

A 59-year-old man who underwent successful aortofemoral bypass had acute appendicitis at an indeterminate time in the postoperative period. Thirteen months later, a pulsatile groin mass developed. After a complicated course, it was found that infection from appendicitis had extended to the body of the graft. This unusual cause of graft infection reaffirms the importance of careful closure of the retroperitoneum over an aortic anastomosis and suggests a relationship of other intra-abdominal inflammatory processes to graft infection.

Fifty patients with biopsy-proven glomerulonephritis and 100 sex- and age-matched controls (50 patients each with non-glomerular renal disease or acute appendicitis) were asked by questionnaire and a telephone interview whether they had been exposed to organic solvents. The questioning and the evaluation of the exposure, if any, was made without knowing the diagnosis of the interviewee. Fifty per cent of the patients with glomerulonephritis reported more than slight exposure, but only 20% of the controls. Exposure to organic solvents may often play a role in the causation of glomerulonephritis.
