It is important to exclude tuberculosis prior to preventive therapy, but this can be difficult in patients with symptomatic human immunodeficiency virus (HIV) disease. Patients with clinically advanced HIV disease were screened for active tuberculosis using a symptom questionnaire, measured weight loss, chest radiography, sputum microscopy and culture prior to receiving tuberculosis preventive therapy. Tuberculosis was diagnosed in 11 of 129 patients screened. A simple screening instrument of two or more of the symptoms measured weight loss, cough, night sweats or fever, had a sensitivity of 100% and specificity of 88.1%, and positive and negative predictive values of 44% and 100%, respectively.

Tuberculosis (TB) is one of the oldest known diseases and has claimed more lives than any other Today, about one-third of the world's population is infected with TB. In 2003, 1,379 cases of new, active and relapsed TB were reported in Canada. TB is caused by Mycobacterium tuberculosis. Only 10 per cent of infected individuals will develop active TB. Pulmonary TB can be spread by an infectious person through the aerosolization of droplets when coughing, talking, spitting, sneezing or singing. Symptoms of pulmonary TB are a cough with or without sputum production lasting at least three weeks, chest pain, hemoptysis, fever, night sweats, weight loss, lack of appetite, chills and weakness. Extrapulmonary TB is generally not associated with person-to-person spread. Common sites include the throat, lymph nodes, abdomen, intestines, long bones of the legs, spine, kidneys, bladder, skin, eyes and meninges. The risk factors for TB infection and disease include close contact with an active pulmonary TB case, HIV infection or AIDS, inactive disease not adequately treated, low income, underlying medical condition, homelessness, alcoholism, injection drug use, aboriginal background or occupation in health care. Risk settings include travel or residence in an endemic area or work or residence in a correctional facility, shelter, rooming house, residential facility, hospital or long-term care facility. Nurses need to advocate for the prompt diagnosis and isolation of suspected and confirmed TB cases. Knowing when to institute such measures as isolation in a negative pressure room, using respirator masks and limiting interpersonal contacts is vital to the nursing care of TB patients. In addition, the role of the public health department needs to be understood; for example, all jurisdictions have legislated requirements for reporting new positive TB skin tests to public health.

Tuberculosis (TB) is often mistaken for community-acquired pneumonia (CAP). To avoid missing the diagnosis, we recommend that any CAP patient with upper lobe infiltrate, cavitation, miliary pattern, hemoptysis or >1 month of any of cough, fever, malaise,weakness, night sweats, or significant weight loss, should have sputa submitted for Mycobacterium tuberculosis smear and culture. Any CAP patient failing or relapsing after empiric therapy should be investigated for TB. In the presence of HIV with low CD4 count (< or = 200 cells/mL), the presentation may be atypical, and therefore sputa should be submitted for M tuberculosis. Any HIV patient, regardless of CD4 count, with a known history of positive tuberculin skin test, previous TB, or recent exposure to TB, who presents with CAP, should be investigated for TB.

The medical and imaging data of a 59 year old male is reported. The patient presented with cough, fever, night sweats and weight loss, for which a final diagnosis of multivisceral tuberculosis (with peritoneal involvement and mycotic aneurysm) was made, by means of CT, MRI and laparoscopic findings. This disease is uncommon in developed countries with subjects lacking the usual risk factors. Because delayed treatment may be lethal, especially with such serious vascular complication, the authors review the value and limitations of CT and MRI along with the suggestive features.

A 48-year-old white woman was admitted to the hospital with low-grade fever, night sweats, fatigue, nonproductive cough with dyspnea, bilateral knee pain, and swelling that progressed slowly over 6 weeks. She was a 30-pack-year smoker, and had received outpatient antibiotic therapy with clarithromycin and then cephalexin without improvement. The admission chest radiograph showed bilateral interstitial infiltrates, and an effusion was seen on knee radiographs. She was treated with levofloxacin, cefepime, and methylprednisolone with some improvement, but fevers persisted up to 104 degrees F/40 degrees C. She also developed multiple painful skin nodules (Figure 1) and an enlarging painful tongue ulcer (Figure 2). Her bilateral knee swelling and pain also worsened, and a bone scan showed increased activity. Skin biopsy showed acute and chronic inflammation with an abscess that contained "yeast" (Figure 3). Fungal culture from the skin lesion and joint fluid aspirate grew Blastomyces dermatitidis. Urine antigen and blood antigen enzyme-linked immunoassays for B. dermatitidis were positive. The patient was started on a 6-month course of itraconazole oral solution with slow resolution of her joint inflammation and skin lesions over the next several weeks.

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.

The global social, political and health emergency presented by the human immunodeficiency virus and the acquired immune-deficiency syndrome (HIV/AIDS) has also once again propelled tuberculosis (TB) into a global public health emergency. The examples I will use to show how activism and social mobilisation can assist in overcoming TB are primarily from my home country, South Africa. Despite significant differences in health systems, culture, politics and history, there are lessons that could be used to advocate for TB prevention, diagnosis, treatment and care globally. Our country experiences globally significant HIV and TB epidemics. I will return to the epidemiology of TB-HIV and the crisis of illness and death. Early in April 2005, one of my closest friends, Ronald Louw, a professor of law at the University of KwaZulu-Natal, a human rights lawyer and activist for more than 25 years, suffered a persistent fever and cough. While on sabbatical, he was taking care of his mother who had been diagnosed with cancer. He assumed his illness was stress-related and went to a doctor who diagnosed bronchitis. After 4 weeks' treatment with antibiotics, his illness was worse-he had a raging fever, night sweats and was becoming disoriented. He requested an HIV test. Within 24 hours Ronald Louw knew that he had been infected with HIV. His mother died on the same day. He also knew within 24 hours that his CD4 count was below 100. They could not diagnose his lung disease and concluded that it was Pneumocystis carinii pneumonia. Four weeks later his doctors diagnosed TB through a lung biopsy. Ronald Louw had been desperately sick under medical care with TB and HIV for more than 8 weeks. He died 3 days after receiving a definitive TB diagnosis, and a week after treatment for presumptive TB had commenced.

In this study, the aim was to investigate the performance of number-II Dispensary of Tuberculous Control (DTC) in Gaziantep in 2004. The patients diagnosed to have tuberculosis between 2004 January 1st and 2004 December 31st were included. The patients registries were evaluated retrospectively. The mean age of the patients was 28.92+/-14.43 years (ranged between 1-68), 70.5% of the cases were male, and 72.5% of the cases were between 15-44 years old. Forty-two (82.3%) of the cases had the diagnosis of lung tuberculosis. 47% of them did not have any health insurance. The symptoms detected in the patients were cough, night sweats, sputum and hemoptysis respectively. There was no symptom registry in ten patients (19.6%). Sputum analysis to detect acid-fast bacilli (AFB) was done in 18 patients (19.6%). AFB was perfomed in 3.9% of the patients following two-months of therapy, and in 1.9% of the patients at the end of the therapy. Diagnostic tuberculous culture was performed in only one patient (1.9%). There was no tuberculous culture performed neither at the second month nor at the end of the therapy course. AFB was found to be positive in direct or concentrated sputum samples in eight (44.4%) of the patients. All the patients were evaluated with radiographies. The eritrocyte sedimentation rate was measured in 33.3%, 9.8%, and 15.6% of the patients before the therapy, at the end of the two months of therapy, and at the end of the therapy, respectively. The diagnosis was established with radiology clinical findings in 34 patients (66.6%). Directly observed therapy was performed in one patient (1.9%). The cure rate among smear positive patients was 12.5%, and the 100% of the patients were completed the therapy. There exists many problems with tuberculosis "warfare" and we believe the solution lies in DOTS.

This is a metastatic spread of squamous cell lung carcinoma to lungs, liver, lymph node, bone and subcutanous region as multiple abscess-like lesions. A fifty-five years old man admitted to the out-patient clinic with fever, cough, hemopthysis, night sweats, chest pain, abdominal pain and weight loss. In a short period of time abcess like lesions developed in his lungs, liver, lymph node, bone and subcutanous region. Though the clinical presentation is suggestive for an infectious condition, no success to antimicrobial treatment and negative results of microbiological studies have arised a need to further investigations. Histopathological studies of the abscess wall ultimately gave the definitive diagnosis as metastatic squamous cell carcinoma. We believe that case report is interesting because of the uncommon metastatic lesions masquerading the abscesses and also wide-spread multiple distant invasions of a squamous cell lung carcinoma in a short time period.

The patient, an 18-year-old girl, was found to have strong positive purified protein derivative of tuberculin (PPD) test and calcified focus in her liver 2 years ago. She denied fever, cough, sputum, weight loss, night sweats, fatigue, and anorexia. After admission, physical examination, laboratory tests, CXR, abdominal CT, colonoscopy and gynecological examination were all normal except for the liver lesions. Percutaneous needle biopsy was performed under sonographic guidance and pathological examination showed caseous granuloma. She was diagnosed as primary liver tuberculosis and the lesions decreased after 2 months' therapy of isoniazid, rifampicin and ethambutol. Primary liver tuberculosis could be asymptomatic and manifested as calcified focus; percutaneous needle biopsy and pathological examination is helpful for the diagnosis. The asymptomatic liver lesions are still an indication for anti-tuberculosis therapy.
