The results of treatment in patients, in whom biliary calculous disease and inflammatory and cystic diseases of abdominal organs were diagnosed simultaneously, were analyzed. Main aspects of diagnosis and prognostication of efficacy of simultant operations conduction, technical rules of surgical interventions were presented. In such patients there were elaborated indications for performance of simultant completely laparoscopic and laparoscopic combined operations.

Retrospective case series from Thailand have reported the presence of intra-abdominal abscesses in around half of patients with melioidosis, a much higher rate than our clinical experience would suggest. We performed a prospective, observational study of 230 adult patients with culture-confirmed melioidosis in which all patients underwent abdominal ultrasound. One or more abscesses were detected in the liver and/or spleen in 77 (33%) cases. These were often multiple (70%, 31/44 in hepatic abscesses and 88%, 50/57 in splenic abscesses) and clinically silent (27% of cases with abscesses presenting with abdominal pain). The mortality rate at 4 weeks post-discharge was lower in patients who were abscess-positive vs abscess-negative (10%, 8/77 vs 20%, 31/153)., (Copyright © 2012 Royal Society of Tropical Medicine and Hygiene.

From January 2005 to January 2010, 668 consecutive patients with lymphoproliferative disease were retrospectively identified. Hepatic infiltration was present at initial staging in patients with non-Hodgkin's lymphoma [12 of 364=3.3%; age median=45; male:female (M:F)=10:2] but also Hodgkin's disease (5 of 41=12.2%; age median=19; M:F=0:5) and multiple myeloma (3 of 162=1.8%; age median=60; M:F=2:1). There were no cases of hepatic infiltration in 101 patients with leukemia. There are typical radiological patterns of hepatic involvement in lymphoproliferative disease with typical lesions characteristics., (Copyright © 2012 Elsevier Inc. All rights reserved.)

Nosocomial fungal infection increases gradually and has become the leading pathogen at National Taiwan University Hospital since 1993. From January 1995 through May 2002, hepatosplenic fungal infection (HSF) was diagnosed in 37 (7.4%) of the 500 adult patients with acute leukemia who received chemotherapy at this hospital. There was no significant difference in the incidence of HSF between the patients with acute myeloid leukemia and those with acute lymphoblastic leukemia, or between the patients treated with high-dose chemotherapy and those with conventional or low-dose chemotherapy. Candida tropicalis was the leading pathogen, followed by Candida albicans. The computed tomography scan showed multiple hypodense lesions in the liver (89%), spleen (70%), and kidney (27%). Eighteen patients were initially treated with fluconazole and 19 with amphotericin B. Nineteen patients received the planned chemotherapy after the diagnosis of HSF. Among them, eight patients underwent hematopoietic stem cell transplantation and seven patients survived more than 100 days post-transplantation; none of these patients had relapse of prior HSF. Twenty-three patients (62%) died during a median follow up of 10 months, but only seven died due to HSF. In conclusion, a substantial percentage of patients with acute leukemia acquired HSF after chemotherapy and carried high mortality. However, HSF itself is not a contraindication for subsequent chemotherapy and hematopoietic stem cell transplantation.

To outline the characteristics and define appropriate management of chronic hepatosplenic suppurative brucellosis (CHSB), 905 patients with brucellosis were analyzed. Sixteen episodes of CHSB (14 in the liver and 2 in the spleen) were found in 15 patients. Six patients had had previous remote brucellosis. Twelve patients presented with systemic symptoms, and 12 with local symptoms. Cultures of blood samples yielded negative results in all cases except 1, and the results of cultures of pus specimens were positive for Brucella melitensis in only 2 cases. All patients showed calcium deposits surrounded by a hypodense area on computed tomography. Patients often had low titers of agglutinating antibody. In patients who were receiving conservative management, early response was successful in 50% and late response was successful in 33.3%. In the patients who underwent surgery and concomitant antibiotic therapy, early and late response was successful in 100%. Thus, CHSB mainly represents a local reactivation of previous brucellosis. Its diagnosis may be difficult to establish and surgery may be required to cure many patients.

The objective of this study was to epidemiologically describe potential infectious agents among rural people in the Republic of Yemen. This would aid clinicians in designing empirical therapy and public health officials in planning disease prevention. We sought to examine evidence for the geographical distribution of pathogens causing human hepatic and splenic disease among villagers and domestic animals living in three remote areas with differing altitudes. In June 1992, a cross-sectional survey was conducted at three survey sites of differing altitudes: 3080, 1440 and 250 m above sea level. Questionnaires, parasitic and serological tests were administered to 627 human volunteers. Additionally 317 domestic animals were studied. Malaria, schistosomiasis, and hepatitis B and C infections were found to be likely causes of human hepatic or splenic disease. Additionally, evidence of human and animal infections with the agents of brucellosis and Q fever was found: IgG antibodies against hepatitis E virus were discovered in two (2.0%) of the 100 volunteers. The prevalence of markers for human and animal disease was often lowest at the village of highest elevation, suggesting that increasing altitude, as a surrogate or a true independent risk factor, was protective against infection with the agents studied.

Hepatosplenic candidiasis (HSC) is an increasingly recognized complication of treatment with chemotherapeutic agents. The true incidence of HSC is not known, but most experts agree that there has been an increase in its occurrence during the past 15 years, and most of them attribute this rise to the use of more intensive chemotherapeutic regimens in the treatment of hematologic malignancies, especially, acute leukemia. The most recognizable risk factor predisposing for this complication is prolonged neutropenia. The diagnosis of HS requires high clinical suspicion and expertise in the interpretation of the histopathologic and radiologic data. Most importantly, treatment of the condition requires prolonged administration of antifungal drugs and continuous monitoring using combination of clinical, laboratory and radiologic tests in order to ascertain eradication of the infection. In this minireview I will present a summary of the data available in the literature in combination with our prospective experience in the investigation of HSC.

We studied the incidence among, risk factors for, and survival of adult patients with acute leukemia and hepatosplenic candidiasis during the period 1980 to 1993. Of 562 adult patients with acute leukemia, 38 (6.8%) had hepatosplenic candidiasis. The incidence of infection increased fivefold during the study period. The incidence was higher among patients with acute lymphatic leukemia (11.3%) than among those with acute myeloid leukemia (5.1%) (P = .01). The median survival was 9.5 months, and by the end of follow-up, 74% of patients had died. Patients whose leukemia was in remission before the last cytotoxic treatment preceding hepatosplenic candidiasis survived longer than did patients with newly diagnosed or refractory or relapsed leukemia (P = .0065). Eleven patients died within 3 months after the diagnosis of the infection: 7 of 16 with newly diagnosed leukemia, 4 of 10 with refractory or relapsed leukemia, and 0 of 12 with leukemia in remission (P = .028). In all of the patients who died within 3 months, infection was found at autopsy. In conclusion, the incidence of hepatosplenic candidiasis has significantly increased since 1980, and the outcome for patients with this infection is related to the stage of leukemia.

Hepatic dysfunction frequently develops in patients infected with the human immunodeficiency virus (HIV). This retrospective study was undertaken to determine the laparoscopic and histologic findings in a group of HIV-seropositive patients with or without the acquired immune deficiency syndrome (AIDS). Fifty-four patients, 44 with AIDS and 10 HIV-positive, underwent laparoscopic examination and visually guided biopsies for the assessment of clinical or biochemical evidence of liver injury. Significant abnormalities were detected in 31/44 (70%) AIDS patients and 3/10 (30%) HIV-positive patients. Overall, specific laparoscopic findings were described in 25/54 (46%). The most common findings were peritoneal involvement, massive intra-abdominal adhesions, focal lesions of the liver or spleen, and diffuse nodularity of the liver; these were usually related to opportunistic infections or neoplasms such as non-Hodgkin's lymphomas and Kaposi's sarcoma. No procedure-related deaths occurred. Laparoscopy is a safe and accurate method to detect underlying disease in a selected population of HIV-seropositive patients.
