Gastrointestinal tuberculosis is defined as infection of the peritoneum, hollow or solid abdominal organs, and abdominal lymphatics with Mycobacterium tuberculosis organisms. Gastrointestinal tuberculosis is relatively rare in the United States and is the sixth most common extrapulmonary location. Populations at risk include immigrants to the United States, the homeless, prisoners, residents of long-term care facilities, and the immunocompromised. The peritoneum and the ileocecal region are the most likely sites of infection and are involved in the majority of cases by hematogenous spread or through swallowing of infected sputum from primary pulmonary tuberculosis. Pulmonary tuberculosis is apparent in less than half of patients. Patients usually present with abdominal pain, weight loss, fever, anorexia, change in bowel habits, nausea, and vomiting. The diagnosis is often delayed and is usually made through a combination of radiologic, endoscopic, microbiologic, histologic, and molecular techniques. Antimicrobial treatment is the same as for pulmonary tuberculosis. Surgery is occasionally required.

A 66-year old female suffering from rheumatoid arthritis was treated with methotrexate and intra-articular steroid injections. She had gone through pulmonary tuberculosis at the age of 2 years, also, surgery had been performed 2 years ago because of perforated sigmoid diverticulitis. The patient now presented with episodes of abdominal pain and diarrhea as well as occasional night sweats. Laboratory investigation (normal BSR, CRP and white blood cell counts) did not indicate the presence of an inflammatory process, such as reoccurrence of diverticulitis. However, leukocyturia was repetitively found in this patient with the conventional urine culture yielding no significant bacterial growth. Further urine investigation did not indicate infection with Chlamydia trachomatis or Neisseria gonorrhoeae. Ziehl Neelson stains of morning urinary samples did not show acid-fast rods, however, Mycobacterium tuberculosis was finally isolated by culture. Thus, urogenital tuberculosis was finally diagnosed in this patient. Infection, hematogenic dissemination, and spontaneous remission of pulmonary tuberculosis had occurred more than 60 years ago. After a long latent period, reactivation of tuberculosis happened during drug-induced immunosuppression. The patient was successfully treated with an anti-tuberculosis triple-drug therapy during 2 months followed by a double-drug therapy during 4 months.

The antitumor necrosis factor, infliximab, has been recently shown to be effective in refractory sarcoidosis including the intestinal form of this disease. We have tried this therapy in a 55-year-old woman under immunosuppressive therapy for longstanding sarcoidosis presenting with abdominal pain apparently caused by a colonic localization of the disease. The latter diagnosis was based, as recommended, on the presence of nonnecrotizing granulomas in mucosal biopsies, the presence of systemic disease, and the careful exclusion of other granulomatous diseases, including tuberculosis. After the first IV infusion (10 mg/kg BW), she quickly improved, but the wellbeing lasted approximately 4 weeks. She then received another dose of infliximab, but she soon developed low-grade fever and weakness and shortly succumbed of miliary tuberculosis. Likely, infliximab precipitated a pre-existing mycobacterial infection of the intestine. Given the likelihood of underdiagnosing intestinal tuberculosis--and the risks associated with infliximab treatment--this case suggests that this drug should be used with extreme caution, if at all, when a diagnosis of colonic sarcoidosis is suspected.

Cases of disseminated Mycobacterium avium infections in dogs are rare because it appears that the species is innately resistant to infection. A 2-year-old, castrated, 5 kg Shih Tzu-Poodle-cross developed anemia, abdominal pain, lethargy, and splenomegaly. Histological examination of surgically removed spleen indicated marked granulomatous splenitis with myriad intracytoplasmic acid-fast bacterial rods. Ultrastructural examination revealed the presence of 3-4-microm-long mycobacteria in phagolysosomes of epithelioid macrophages. Tissue extract of lightly fixed spleen was positive for M. avium 16S ribosomal RNA and negative for M. tuberculosis complex IS6110 DNA by polymerase chain reaction testing. Anemia was associated with the presence of mycobacteria-infected macrophages in bone marrow. The animal's condition deteriorated, and euthanasia was performed after a clinical course of 2 months. The principal morphological findings at necropsy were severe diffuse granulomatous hepatitis, enteric lymphadenomegaly, and segmental granulomatous enteritis with intralesional mycobacteria present. Mycobacterium avium was cultured from enteric lymph nodes sampled at necropsy. The source of infection was not established but was presumed to be environmental with an enteric portal of entry.

Portal vein thrombosis (PVT) seems rare among HIV infected patients. Even though, the report of such cases is of great interest because it may help to determine the factors of occurrence. We describe cases of PVT in 4 HIV-infected men, aged 32 - 64. Two of them were co-infected with hepatitis C virus (HCV). The four patients had a history of disseminated mycobacterial infection (one case of tuberculosis, 3 cases of mycobacterium avium complex infection) with abdominal lymphadenitis. Despite HAART, their immunodeficiency was profound (CD4: 65 to 216/mm(3)). At the time of diagnosis, two patients were treated with protease-inhibitor containing regimen: indinavir (one case), ritonavir-saquinavir (one case). PVT was revealed by haematemesis (one case), abdominal pain (ome case), anasarca (2 cases). In three patients, the diagnosis of PVT was confirmed by imagery (echo-doppler or angio- RMI), and for the last patient, PVT was found during the transjugular intrahepatic portosystemic shunt setup. A low level of C protein was diagnosed in one case. Cirrhosis was not found in HIV-HCV co-infected patients. Two patients died early after diagnosis, one patient died 3 years after the onset of symptoms. Various factors may cause the development of a PVT in HIV infected patient. Serious immunodeficiency, opportunistic infections such as tuberculosis and mycobacterium avium complex related infection with abdominal lymphadenitis can further the development of PVT. Protease-inhibitor might have facilitated the process. Due to the severe prognosis of advanced cases, early evocation of diagnosis is needed.

Abdominal tuberculosis (TB) is a rare manifestation, which can be overlooked on long-lasting and non-specific findings unless a high index of suspicion is maintained. The purpose of the present study was to investigate the diagnostic features of 39 patients hospitalized with tuberculous peritonitis (TBP) in Dicle University Hospital, Turkey between January 1994 and August 2003. Twenty-two patients were male; patient age ranged between 1 and 59 years (mean: 16.2 +/- 14.4 years). There were 21 patients (54%) under 15 years of age. Thirteen children had a history of familial TB and seven adults had prior history of TB. Six (29%) of 21 pediatric cases had bacille Calmette-Guerin (BCG) scars and results of 5-tuberculin units (TU) tuberculin test were positive in seven children (18%). Of all cases, the most common presenting findings were abdominal pain (95%), ascites (92%) and abdominal distention (82%). Five of the patients had accompanying pulmonary TB, and six patients (15%) had intestinal TB who were admitted to emergency service with acute abdomen, of whom three (8%) had perforation and three (8%) had ileus. Histopathologically 20 cases (51%) were proven on abdominal ultrasonography, and computed tomography revealed most commonly ascites and thickening of peritoneum. No microbiologic evidence was obtained except three positive culture results for Mycobacterium tuberculosis. As a result, TBP should be considered for diagnosis, in patients with non-specific symptoms of abdominal pain, wasting, fever, loss of appetite, abdominal distension and even symptoms of acute abdomen, because early diagnosis and effective treatment will decrease morbidity and mortality.

We reviewed empyema management at our center since video-assisted thoracoscopic surgery (VATS) was introduced. Between 1991 and 2003, 58 patients (34 male, 24 female) ages 1 day to 17 years (median, 6 years) were identified. The median interval from the onset of symptoms to presentation was 7 days; 31% of patients received inpatient care at another hospital, and 24% were from northern communities, including the Arctic. Symptoms included fever (100%), cough (66%), shortness of breath (46%), chest pain (38%), and abdominal pain (17%). Most patients (96%) had pneumonia. The most common organisms were Streptococcus pneumoniae (22%), group A streptococcus (8%), and Mycobacterium tuberculosis (3%). No organisms were identified in 31% of patients. One empyema was trauma-related and one was due to complications of esophageal stricturoplasty. All patients received intravenous antibiotics (median, 17 days). Three patients had thoracentesis, 17 had chest tubes, 3 had thoracentesis and chest tubes, 26 had VATS, 6 had thoracotomy, and 3 had minithoracotomy. Median operative times were 86 minutes for VATS, 90 minutes for thoracotomy, and 75 minutes for minithoracotomy. Median total length of stay (LOS) was 15 days for VATS, 20.5 days for thoracotomy, and 21 days for minithoracotomy. The median preoperative LOS was longer for thoracotomy (10 days) than for VATS (5 days) or minithoracotomy (1 day). The median postoperative LOS was 14 days for VATS, 9.5 days for thoracotomy, and 8 days for minithoracotomy. Our experience shows that VATS is a safe and effective approach to managing children with empyema. The shorter preoperative LOS for VATS is likely due to earlier surgical referral and intervention using less invasive surgical procedures.

Invasive amoebiasis is rarely seen in human immunodeficiency virus (HIV)-infected individuals, even in endemic areas. By contrast, cytomegalovirus (CMV) disease is recognized as a major clinical problem in acquired immunodeficiency syndrome patients. A 34-year-old HIV-infected man with amoeba colitis, disseminated Mycobacterium avian complex and CMV infection with cecum perforation, presented with the initial symptoms of fever, shortness of breath and painful sensation when swallowing. He was treated with fluconazole, trimethoprim-sulfamethoxazole and hydrocortisone under the impression of esophageal candidiasis and Pneumocystis jiroveci pneumonia. However, diarrhea and abdominal pain developed on day 6 of hospitalization. Invasive amoebiasis and CMV colitis was diagnosed after examination of colon pathological specimens. Emergent laparotomy was performed. Right hemicolectomy with double barrel ileostomy and colostomy was done due to perforation of the cecum. Iodoquinol was given, followed by metronidazole 14 days afterwards. He underwent closure of double barrel ileostomy and colostomy 5 months later. This case illustrates the diagnostic challenge of caring for acquired immunodeficiency syndrome persons with multiple illnesses and medication use. CMV infection, amoebic colitis and possibly corticosteroid may have played a role in colon perforation in our patient.

The immune reconstitution syndrome caused by nontuberculous mycobacterial (NTM) infection is reported in 9 of 153 HIV-infected children 2 to 26 weeks after initiation of antiretroviral therapy. The clinical syndrome included fever and dyspnea (2 children), fever and abdominal pain (3), subcutaneous nodules or suppurative lymphadenitis (4). The causative species were Mycobacterium avium (4), Mycobacterium scrofulaceum (3), Mycobacterium kansasii (1) and Mycobacterium simiae (1).

A 47-year-old man from Armenia presented at the emergency department with abdominal pain. He had had a kidney transplant 2 years earlier for renal failure caused by amyloidosis that was secondary to familial Mediterranean fever. He was also known to have chronic hepatitis B with persistent viraemia. He had not received any prophylactic anti-tuberculosis treatment due to impaired liver function, but an extensive work-up was performed prior to transplant, including chest radiography, a Mantoux tuberculin skin test and cultures from 3 consecutive fasting gastric lavage samples, which were all negative for active or latent tuberculosis infection. The patient had presented at the emergency department repeatedly with abdominal pain that was attributed to the familial Mediterranean fever. During his last visit his complaints were accompanied by vomiting, coughing, night sweats and weight loss. He was diagnosed with an intestinal perforation with faecal peritonitis and underwent several laparotomies to treat the faecal peritonitis. Histopathological examination of resected bowel tissue revealed granulomatous inflammation, and acid-fast bacilli were seen with appropriate staining. Later, cultures appeared to be positive for normally sensitive Mycobacterium tuberculosis. The patient died as a result of the disseminated tuberculosis. In immunocompromised patients, tuberculosis often has an atypical course and an increased chance of dissemination that may be difficult to recognize.
