Two patients with acute appendicitis are discussed. On histologic examination both were found to have tuberculosis associated with pyogenic infection. Subsequent investigations failed to reveal tuberculous lesions elsewhere in the body. Both patients have responded well to appendectomy and antituberculous drug therapy.

A case of intrauterine blood passing into the abdominal cavity and resulting in a clinical picture similar to acute appendicitis is presented. To our knowledge, hematometra presenting in this manner has not been reported in the medical literature. Some disease processes which more commonly mimic acute appendicitis include nonspecific mesenteric adenitis, gynecologic disorders, diverticulitis, and urinary tract infection. Unusual diseases presenting in this manner include splenic torsion, infarcted omentum, ileocecal tuberculosis, and duodenal hematoma.

The treatment of acute leukemia in childhood has been increasingly successful. Infectious complications are the major cause of morbidity and mortality among these patients receiving aggressive chemotherapy. In particular, neutropenic enterocolitis or typhlitis has had a reported mortality of 50% to 100%. The authors reviewed a series of 77 previously untreated patients with acute myelogenous leukemia begun on treatment from March 1976 to June 1984 to better define the characteristics of typhlitis and its optimum management. Twenty-five patients had episodes of typhlitis, characterized by fever, abdominal pain, and tenderness, occurring during periods of neutropenia. Ten of these patients had watery diarrhea as a major additional symptom, and nine patients had a significant episode of gastrointestinal bleeding. In seven instances, blood culture results were positive, all for intestinal flora. The episodes of typhlitis occurred most frequently during the induction therapy (19 patients). Five patients experienced typhlitis during maintenance therapy, and one patient had acute appendicitis. Two patients had typhlitis during their reinduction therapy, and of note, one had had abdominal symptoms during her initial induction. All patients were treated initially with broad-spectrum antibiotics and bowel rest. Four criteria have been used for surgical intervention: (1) persistent gastrointestinal bleeding after resolution of neutropenia and thrombocytopenia and correction of clotting abnormalities; (2) evidence of free intraperitoneal perforation; (3) clinical deterioration requiring support with vasopressors, or large volumes of fluid, suggesting uncontrolled sepsis; and (4) development of symptoms of an intra-abdominal process, in the absence of neutropenia, which would normally require surgery. Using these criteria, five patients required surgical intervention for typhlitis or its sequelae and one for acute appendicitis. There was one perioperative death resulting from miliary tuberculosis. Among the 21 patients managed medically, there was 1 death resulting from typhlitis in a patient in whom surgery was deferred because of her multiple failures to enter remission.

A case of acute segmental inflammation of the terminal ileum in a female patient, who presented with signs and symptoms of acute appendicitis is reported. She had an associated bilateral pulmonary tuberculosis. The role of Mycobacterium tuberculosis in the etiology of the segmental ileal disease, and the relationship of the acute disease of the ileum to Crohn's disease is discussed. Henoch's purpura whose intestinal manifestations may mimic acute regional ileitis is discussed in the differential diagnosis.

Both of tuberculous mesenteric lymphadenitis and tuberculous peritonitis are now rather rare in parallel with the decrease of the incidence of tuberculosis as a whole. Here, we report a case of tuberculous mesenteric lymphadenitis complicated with tuberculous peritonitis. A 28-year-old man was admitted to our hospital with pulmonary tuberculosis. Antituberculous chemotherapy was started and his chest X-ray findings were improved. After 11 weeks of the treatment, high fever of 39.0 degrees C developed suddenly and he complained right lower abdominal pain. During laparotomy performed on suspicion of acute appendicitis, swelling of mesenteric lymph-nodes, numerous miliary tubercles on mesentery and turbid ascites were noticed. Diagnoses of tuberculous mesenteric lymphadenitis and tuberculous peritonitis were confirmed by bacteriological and histological examinations of lymph-nodes and tubercles. Ileocecal resection was performed and clinical course after the surgery was favourable.

For studying abdominal tuberculosis (TB) in Ahmadi, files off all patients admitted to our hospital with abdominal TB over 15 years (1981-1996) were reviewed. Nineteen patients are reported here. Young adults were predominant in our study. The non-Arab Asians were the most frequently affected group in relation to their population in Ahmadi, and Kuwaitis were the least frequently affected group. Abdominal pain, sweating, anorexia and fever were the most frequent presenting symptoms. Ascites and intestinal obstruction were the most frequent clinical presentations. Two patients presented with acute appendicitis and one patient had tuberculous pancreatitis. Abdominal lymph nodes, peritoneum, ileum and and caecum were the most frequently affected abdominal structures. We found laparoscopy very helpful in diagnosis of abdominal TB and we recommend it as the diagnostic method of choice. All our patients responded well to antituberculous chemotherapy. It should be kept in mind that abdominal TB still affects the indigenous and expatriate population of Kuwait.

Autoantibodies specific to the cytoplasmic components of neutrophils and monocytes are associated with vasculitis and other idiopathic inflammatory disorders. In this study, using enzyme-linked immunosorbent assay (ELISA) and immunofluorescence assays, sera from patients with acute and chronic infection were examined for the presence of anti-neutrophil and anti-monocyte antibodies: cystic fibrosis (n = 23), acute appendicitis (n = 22), tuberculosis (n = 26), acute gastroenteritis (n = 38), bronchiectasis (n = 9) and chronic granulomatous disease (n = 6). Sera from patients with Wegener's granulomatosis (n = 14), rheumatoid factor positive (n = 15) and healthy volunteers (n = 20) were used as positive and negative controls. In patients with chronic infection, using an ELISA assay, antibodies reactive with neutrophil or monocyte components (% reacting with monocyte components in parenthesis) were found in: 70% (39%) of patients with cystic fibrosis, 4% (38%) of patients with tuberculosis, 0% (33%) of patients with bronchiectasis and 0% (17%) of patients with chronic granulomatous disease. When these sera were examined using an immunofluorescence assay, all of the positive samples were found to react with the cytoplasmic component of neutrophils or monocytes. In patients with acute infection no antibodies (either IgG or IgM) were detected against neutrophils or monocytes. These findings imply that antibodies directed against neutrophil cytoplasmic components are predominantly associated with chronic pyogenic infection and antibodies specific to monocyte cytoplasmic components are predominantly associated with chronic granulomatous infection. This mirrors the findings in idiopathic inflammatory disease where anti-monocyte antibodies are associated with granulomatous disorders such as sarcoidosis, and anti-neutrophil antibodies are associated with neutrophilic disorders such as ulcerative colitis. These results suggest that chronic stimulation of phagocytes by infectious agents may result in the generation of a humoral response against phagocyte cytoplasmic components. This furthers our understanding of humoral immune responses against phagocytic cell components during infection.

The anaphylatoxin derived from the fifth component of the human complement system (C5a) mediates its effects by binding to a single high-affinity receptor (C5aR/CD88), the expression of which has been traditionally thought to be restricted to granulocytes, monocytes, macrophages (Mphi), and cell lines of myeloid origin. Recent immunohistochemical data suggested that human bronchial and alveolar cells express C5aR as well. To reexamine the tissue distribution of human C5aR expression, transcription of the C5aR gene was investigated in normal and pathologically affected human lung (bronchopneumonia, tuberculosis), large intestine (acute appendicitis, Crohn's disease), and skin (pyogenic granuloma, lichen planus) using in situ hybridization. In contrast to previous evidence, C5aR mRNA could not be detected in pulmonary or intestinal epithelial cells, whereas keratinocytes in inflamed but not in normal skin revealed detectable levels of C5aR transcripts. Additionally, it could be documented that only migrating Mphi express C5aR mRNA, whereas sessile Mphi in normal tissues and epithelioid/multinucleated Mphi found in granulomatous lesions do not. Because C5a has been demonstrated to upregulate the expression of interleukin (IL)-6 in human monocytes, we also studied IL-6 gene transcription in parallel to the C5aR. IL-6 mRNA was detectable in many tissue Mphi. Surprisingly, a tight co-expression of C5aR and IL-6 mRNA was observed in keratinocytes from lesions of pyogenic granuloma and lichen planus. These results point to an as yet unknown role for C5a in the pathogenesis of skin disorders beyond its well-defined function as a chemoattractant and activator of leukocytes.

An unexpected inflammatory cecal mass of uncertain etiology encountered during surgery for presumed appendicitis poses a dilemma to the surgeon when deciding the appropriate operative management. A retrospective study was performed to review the pathology and surgical management of this condition. Among 3224 patients who had emergency surgery for a diagnosis of acute appendicitis between January 1990 and December 1997, a group of 52 patients (1.6%) underwent either ileocecal resection or right hemicolectomy for an inflammatory cecal mass of uncertain etiology. The final pathologic diagnosis was cecal diverticulitis in 26 patients (50%), appendiceal phlegmon or abscess in 21 patients (40%), cecal carcinoma in 3 patients (6%), tuberculosis in 1 patient (2%) and schistosomiasis in another patient (2%). Altogether 34 patients underwent ileocecal resection, and 18 patients underwent right hemicolectomy, including the 3 patients with cecal carcinoma. Ileocecal resection was associated with a shorter mean operative time (144 vs. 201 minutes; p < 0.001), a lower morbidity rate (3% vs. 22%; p = 0.043), and a shortened mean postoperative hospital stay (6.8 vs. 11.2 days; p = 0. 011) than right hemicolectomy. There was no mortality in either group. In conclusion, most inflammatory cecal masses are due to benign pathologies and could be managed safely and sufficiently with ileocecal resection. Careful intraoperative assessment including examination of the resected specimen is essential to exclude malignancy, which would require right hemicolectomy.
