Four out of 24 patients presenting as an emergency with acute non-specific abdominal pain showed serological evidence of infection with Yersinia pseudotuberculosis. Two out of 13 patients presenting with acute appendicitis during the same period also had evidence of Yersinia infection. Viral infection was present in only 1 patient in each group. Since it is rare to find antibodies to yersinia in healthy individuals, it seems likely that yersinia is a cause of some cases of non-specific abdominal pain. Viral infection does not appear to be an important aetiological factor in patients over 12 years of age.

Out of a total of 3347 patients operated on for acute appendicitis 125 were found to be infected with Yersinia enterocolitica. Histological examination revealed a catarrhal-purulent inflammation or a phlegmonous-gangrenous inflammation in 58,6%. This detection of Yersinia enterocolitica does not justify the omission to perform appendectomy, because true appendicitis cannot be ruled out.

An infection with Yersinia strains may develop with the picture of acute appendicitis. Laparotomy will then not reveal an acutely inflamed appendix, but will often show mesenteric lymphadenitis or acute terminal ileitis. These conditions have been observed in four patients. The differential diagnostic possibilities are discussed. It is pointed out that acute terminal ileitis is practically never transformed into chronic terminal ileitis (Crohn's disease).

Crohn's disease of the appendix is an uncommon process that is more frequent in young people. The most common preoperative diagnosis is acute appendicitis. At exploratory laparotomy the appendix is enlarged and malignancy may be suspected. The differential diagnosis may be difficult. Serologic tests and cultures should be performed to exclude Yersinia infections. Appendicectomy is a safe procedure when the disease is limited to the appendix. The postoperative course is usually uncomplicated with a low rate of complications and recurrence. Although it may be a different process than Crohn's disease and the recurrence rate is low, it is suggested that all the patients should be followed-up so that recurrences may be recognized and treated as early as possible. A new case is presented after two years of follow-up without recurrence.

Twenty-four patients with homozygous beta-thalassaemia who had been splenectomised and currently on treatment were studied retrospectively. They were divided into two groups. Group A: who had splenectomy prior to commencement of any regular blood transfusion. The mean haemoglobin for this group rose from 5.5 gm/dl pre-splenectomy to 7.7 gm/dl post splenectomy (p < 0.001). Group B: who were on regular blood transfusion when they had their splenectomy and the mean blood transfusion requirement dropped from 317 ml/kg/yr to 230 ml/kg/yr of packed red cells following splenectomy (p < 0.001). Three patients who were on regular blood transfusion and desferrioxamine developed Yersinia enterocolitica infection. They presented with fever and signs of an acute abdomen. At laparotomy, 2 of the patients had acute appendicitis. All 3 appendices grew Yersinia enterocolitica and one patient also had a Yersinia enterocolitica septicaemia. If a patient develops fever and enteritis, desferrioxamine should be stopped temporarily and cotrimoxazole started as prophylaxis against systemic Yersiniosis. No cases of pneumoccocal sepsis was reported.

An acute disorder of the lower abdomen requires early clarification, whether or not it is of gynaecological or surgical origin. With non-gynaecological affections, beside diverticulitis, Crohn's disease, perforations, bowel obstructions, yersiniosis, vascular diseases (acute embolism, thrombosis or dissection), urological disorders or hernias, acute appendicitis has firstly to be considered. The systematic use of the different diagnostic instruments is discussed.

The discovery of a tumour mass of the appendix, in an acute or chronic context, raises the problem of its benign or malignant, inflammatory or infectious nature. We report five cases of patients operated by the same surgical team between June 1991 and September 1996, who presented macroscopically and histologically with unusual appendicular pseudotumours: appendicular diverticulosis (n = 1), Crohn's disease localized to the appendix (n = 2), yersiniosis (n = 1), actinomycosis (n = 1). The preoperative diagnosis was acute appendicitis (n = 2) or tumour (n = 3). The postoperative course was uneventful in every case, and specific medical treatment was prescribed in two cases (yersiniosis and actinomycosis). These differential diagnoses must be considered in all appendicular diseases, but they are extremely difficult to confirm preoperatively.

Seventy (70) appendiceal specimens and 80 ice-cream samples were analysed to detect Yersinia enterocolitica using three different media. Both Y. enterocolitica and Citrobacter freundii were recovered in appendiceal specimens (17.1% and 8.6%) and ice-cream (26.25% and 18.75%) respectively. Thioglycollate medium was more selective and productive in isolating Yersinia. Y. enterocolitica was the major causative agent of acute appendicitis (11/25, 44%). It was sensitive to chloramphenicol, gentamicin, tetracycline and trimethoprim- sulfamethoxazole.

Background: During the past decade, very little has been published on the relationships between Yersinia enterocolitica, acute terminal ileitis (ATI), and Crohn's disease, possibly due to a decrease in Yersinia infections and, consequently, in ATI. Methods: Fifty-three patients admitted to Herlev University Hospital during the period 1976-1998 were diagnosed as having ATI while undergoing surgery for suspected acute appendicitis. The patients were followed up, and both Yersinia titers and the development of Crohn's disease were registered. Results: Forty-four patients (83%) were tested for Yersinia, 17 of whom (39%; 95% confidence limits, 24-55%) were positive. The incidence of yersiniosis in ATI decreased significantly during the observation period (P<0.05), whereas the incidence of ATI itself was unchanged. Thirteen of the 53 patients (25%; 95% confidence limits, 14-38%) had, in addition to ATI, an inflamed appendix. Three patients developed Crohn's disease during a median observation period of 13 years (cumulative risk 6.1%). None of them had yersiniosis. Conclusions: The incidence of ATI remained stable during the observation period, even though the number of Yersinia infections decreased. This may have been due to an increase in gastrointestinal infections caused by other enteric pathogens. In accordance with previous findings, ATI patients who developed Crohn's disease did not have yersiniosis. Thus, it is still of prognostic value to test patients with ATI for Yersinia and perhaps for other enteric pathogens as well.

Mesenteric adenitis is a self-limited condition characterized by fever, localized right lower quadrant abdominal pain, and frequent leukocytosis, making it difficult to differentiate from appendicitis. We report a case of mesenteric adenitis in an 8-year-old boy who presented at the emergency department with right lower quadrant abdominal pain, diarrhea, and fever up to 40 degrees C. Acute appendicitis was initially suspected, but further abdominal ultrasound and contrast enhanced computed tomography studies showed a normal appendix with marked mesenteric adenopathy. Symptomatic treatment was given and pain and fever subsided 2 days later. Follow-up sonography showed resolution of adenopathy, confirming the diagnosis of mesenteric adenitis. The admission stool cultures grew Salmonella enterica serovar Enteritidis (S. Enteritidis). Unlike previous reports in western countries where Yersinia species prevails and was thought to be self-limited, S. Enteritidis carries potential risk for serious systemic complications, such as meningitis or septic arthritis. The isolation of this unusual microbiological species thus has both therapeutic and epidemiological implications for mesenteric adenitis in Taiwan.
