Study 120 intravenous drug users admitted liver disease clinic and HIV clinic from April to July 2002, the results showed that reasons of 14.2% were routine examinations, the rest were fever, HIV-related conditions or symptoms of liver diseases or gastrointestinal diseases. 57% patients had transaminase level of >100 IU/l. Severe hepatocellular necrosis was remarkable in patients went to liver disease clinic. Important co-infection in 54 patients went to liver disease clinic was HIV-HBV-HVC. Intravenous drug users can be co-infected with many different viruses with severe hepatocellular necrosis, so they need appropriate treatments

Mycobacterium marinum is an uncommon cause of skin and soft-tissue infection. The diagnosis of M. marinum infection is often delayed when only a conventional tissue culture method is used. PCR-restriction fragment length polymorphism (RFLP) analysis using the novel region of the rpoB gene is now available for the rapid identification of Mycobacteria. We report a case of hand infection caused by M. marinum that was identified by PCR-RFLP analysis. The PCR-RFLP assay is a specific and rapid method for the identification of Mycobacteria that facilitates the early diagnosis of non-tuberculous Mycobacterium infection.

Non-tubecrulosis mycobacterium infections were increasingly reported either pulmonary or extrapulmonary in the past decades. In Taiwan, we noticed several reports about the soft tissue infections caused by rapid growing mycobacterium such as Mycobacterium abscessus, Mycobacterium chelonae, on newspaper, magazines, or the multimedia. Most of them occurred after a plastic surgery, and medical or non-medical procedures. Here, we reported two cases of these infections following medical procedures. We also discussed common features and the clinical course of the disease, the characteristics of the infected site, and the treatment strategy. The literatures were also reviewed, and the necessity of the treatment guidelines was discussed.

Few recent reports have indicated that Mycobacterium massiliense causes various infections including respiratory infection. However, there is scarce information on the clinical significance, natural history of the infection, and therapeutic strategy. This report describes a case of an immunocompetent old man infected by M. massiliense that causes acute respiratory failure. In light of the general courses of non-tuberculous mycobacterium infections, rapid progression and fatality are very rare and odd. In addition, we discuss the biological and pathological properties of M. massiliense with the review of cases reported previously including our fatal one.

The nucleotide-oligomerization domain (NOD) is an important molecule involved in host defense against bacterial infection. To study the role of NODs in the host response to Mycobacterium leprae, we measured the mRNA levels of NODs and related genes in infected mouse tissues. The mRNA expression of NOD1, NOD2, caspase-1 and ASC was increased in mouse footpads. Whereas NOD2 expression in macrophages was increased at 2 and 24 h post-infection with M. leprae, there was no expression of NOD1 at these time points. An increase in caspase-1 expression was observed at 2 h and continued at 24 h. However, the expression of ASC was increased only at the early time point. The expression of caspase-1 is regulated by NOD2-dependent pathway in established HEK 293. Our results suggest NOD2, rather than NOD1, may be associated with the host response to M. leprae and that caspase-1 activation is essential for the host response.

Managing chronic cough is diagnostically challenging especially in primary care. This case report highlights the difficulties experienced in approaching a case of chronic cough from a primary care perspective. The discussion also involves the clinical significance and treatment dilemma of M. fortuitum chelonae complex that was isolated from the sputum cultures of an elderly woman who presented with chronic cough for more than a year.

Mycobacterium marinum (M. marinum) is a nontuberculosis mycobacterium that is normally associated with cutaneous lesions. Most cases occur after an individual has suffered minor trauma in association with contaminated fresh or salt water. In immunocompromised patients, M. marinum can cause osteomyelitis, synovitis and/or disseminated infection, which can be mistaken for rheumatoid arthritis (RA) or remitting seronegative symmetrical synovitis with pitting edema (RS3PE). Therefore, precise history taking and specimen culture are very important for early diagnosis and appropriate treatment. We report an unusual case of septic polyarthritis due to M. marinum that was diagnosed by culture and improved with antibiotic therapy.

Non-tuberculous mycobacteria (NTM) are being recognized increasingly as the causative agents of opportunistic infections in humans. This study investigated the epidemiologic trends of NTM recovery from various clinical specimens in 2 Korean tertiary-care hospitals. We reviewed the laboratory records of patient samples cultured for mycobacteria between 2009 and 2015 at 2 tertiary-care hospitals in Korea. The medical records for patients with positive NTM samples were also reviewed. During the study period, 144,540 specimens were cultured for mycobacteria. The proportion of NTM-positive samples increased from 23.3% in 2009 to 48.2% in 2015. The 2 most frequently isolated NTM were Mycobacterium intracellulare (38.3%) and M. avium (23.1%). The number of clinically significant diseases caused by NTM in inpatients and outpatients increased from 6.8 to 12.9 per 100,000 patients over the same period. The rates of recovery of NTM from clinical specimens and the number of patients with NTM infections increased significantly (P < 0.001, testing for trend) between 2009 and 2015.
