A case of a HIV-positive patient hospitalized with acute abdomen secondary to infection by cytomegalovirus (CMV), is presented. Infection by CMV is frequent in HIV-positive patients, with a relevant intestinal affection. However, its presentation as acute abdomen is more rare, although it has to be considered given that the demonstration of the presence of CMV and its potential pathogenic power have important therapeutic connotations. Currently, the use of diagnostic techniques based in specific monoclonal antibodies and DNA hybridization methods increases the diagnostic sensitivity of the traditional methods based on histological demonstration of the cytopathic effect and/or viral cultives.

Infection with the roundworm Ascaris lumbricoides is common in children and may mimic an acute abdomen. The cases of two pediatric patients who presented to the emergency department with signs and symptoms of a surgical abdomen are presented to highlight the presentation of this infection. Both cases were diagnosed by physical examination and radiographs and were treated successfully without surgical intervention. These cases illustrate the need for heightened awareness by the emergency physician of ascariasis in the differential diagnosis of acute abdomen.

Infection, hemorrhage and adult respiratory distress syndrome (ARDS) are pulmonary complications occurring after remission induction therapy for acute leukemia. The aim of this study was to analyze the incidence of these causes by serial roentgenogram, clinical, microbiological and laboratory tests in 21 patients (pts) with relapsed acute leukemia (18 X myeloid, 3 X lymphoblastic), an AML-pt (acute myeloid leukemia) suffering from secondary leukemia, and three pts with primary refractory leukemia following treatment with intermediate (IM) and high-dose cytosine arabinoside (HD-Ara C), in combination with amsacrine (AMSA)(n = 19), etoposide (VP 16) (n = 5) or Mitoxantrone (n = 1). Eleven out of 25 pts developed pulmonary complications, one of them with massive hemoptysis and roentgenographic signs of pulmonary bleeding, one suffering from protracted shock after a tumor lysis syndrome, two pts showing symptoms of a cardiogenic pulmonary edema complicating severe Candida pneumonia in one case and legionnaires' disease in the other. Seven of the eleven pts had a non-cardiogenic pulmonary edema with respiratory failure 1-14 days after cessation of induction or consolidation therapy. In six of the seven, there were no signs of cardiogenic, infectious or metabolic reasons, including fluid overload, for the pulmonary edema, one had as a contributing factor a Candida infection of the lung. Three of the seven patients recovered, four died (two following IM and two after HD-Ara C). Other adverse side effects, clearly attributable to HD-Ara C, included delirious state (n = 3), generalized erythema (n = 3), acute pancreatitis (n = 2), acute abdomen (n = 1) and conjunctivitis in almost all patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Clostridium difficile causes a broad spectrum of enteric diseases in humans, ranging from mild antibiotic-associated diarrhoea to more severe pseudomembranous colitis. The authors report four cases of life-threatening pseudomembranous colitis with haemodynamic changes. Infection due to Clostridium difficile should be kept in mind whenever a patient undergoing antibiotic therapy develops a symptomatology of an acute abdomen.

We report an outbreak of Clostridium difficile-associated disease (CDAD) in a large Dublin hospital. From January to June 1995, inclusive, 139 patients were affected; the mean age of cases was 68.8 +/- 19 years. Clinical information is available for 73 cases identified during the first four months of the outbreak. The majority of patients presented with abrupt onset of watery diarrhoea; however, 19.2% presented with an unexplained pyrexia following a course of antimicrobial therapy and 5.5% presented with a surgical acute abdomen. Twenty patients (27.4%) experienced relapsing disease and seven (9.6%) patients died. Seventy-six percent of cases received a cephalosporin prior to the onset of disease, the highest relative risks occurring with third-generation agents; however, 9.6% of patients affected had not been exposed to antimicrobial therapy in the preceding eight weeks. Pyrolysis mass spectrometry identified two clusters of isolates, representing two strains of C. difficile. There was marked spatial clustering of these strains, with each confined to a separate area of the hospital. Infection control measures and an antibiotic policy were introduced. Throughout the outbreak period the use of the most frequently used cephalosporin in the hospital increased; this was accompanied paradoxically by a reduction in the number of new cases of CDAD.

A peritonitis caused by an ascending infection is a rare complication postpartum. A 37-year-old woman presented with a secondary peritonitis due to Streptococcus pneumoniae. The patient had given birth to a healthy boy 4 weeks before and showed no symptoms of a bronchitis on admission. An operation was performed after the patient developed an acute abdomen, showing a diffuse peritonitis. High vaginal swabs and blood cultures taken on admission were positive for S. pneumoniae as well as the specimen taken during the operation. Thus we concluded that this was a case of an ascending infection. After antibiotic therapy with penicillin the patient could be discharged 8 days after the operation.

Infection with Ascaris lumbricoides is common in tropical and subtropical regions of the world. Prevalence of ascariasis is related to poverty, poor hygiene and poor fecal sanitation. This helminth usually lives harmlessly in small intestine but can also cause intestinal obstruction or perforation peritonitis which is common in childhood. Ascaris can also migrate through ampulla of vater to produce cholangitis, pancreatitis,cholecystitis and rarely hepatic abscess. Ascaris induced hepatic abscess can sometimes present with acute abdomen (like acute pyogenic abscess). We present a young adult with Ascaris induces hepatic abscess who presented and a case of acute abdomen in emergency department.

The aim of this study was to describe the features in the presentation and management of acute abdomen (AA) in patients with human immunodeficiency virus (HIV). We reviewed the medical records of 97 HIV patients who presented with AA and were seen in 2006-2011 at Cayetano Heredia National Hospital in Lima, Peru. 1.6% of immunosuppressed patients underwent surgery. Appendectomy was the most common surgical procedure (33.3%). Morbidity was 28.1% and postoperative mortality was 9.4%. Infection by mycobacterium tuberculosis was the most common cause of acute abdominal pain, at 26.8%. Data suggest that an early surgical decision for cases of AA in HIV patients may prevent significant morbidity and mortality.
