  • Toxoplasma gondii is an obligate intracellular protozoan that is distributed worldwide. Recently, several tests for avidity of Toxoplasma IgG antibodies have been introduced to help discriminate between recently acquired and distant infections. The study was conducted in Jawaharlal Nehru Medical College and Hospital, India from February 2011 to September 2012. Serum specimens were subjected to Toxoplasma IgM ELISA and IgG avidity ELISA test. Out of 48 patients with abortions, 17 (35.4%) were positive for IgM ELISA, and 8 (16.6%) had low IgG avidity antibodies. Out of 48 patients with other obstetric problems, 23 (47.9%) were positive for IgM ELISA, and 17 (35.4%) had low IgG avidity antibodies. Combining both groups on avidity test, only 25 of 40 (62.5 %) IgM-positive women had low-avidity IgG antibodies suggesting a recent T. gondii infection in these women. More importantly, 15 (37.5%) of the IgM-positive women had high-avidity antibodies suggesting that the infection was acquired before gestation The relation of IgM seropositivity with the following risk factors was not found to be statistically significant; contact with cats (0.13), non-vegetarian food habits (0.05), and low socio-economic status (0.49). While, for IgG avidity ELISA, only contact with cats (0.01) was significantly associated with seropositivity. All other risk factors have P-values of >0.05 (not significant). IgG avidity test when used in combination with IgM test was a valuable assay for diagnosis of ongoing or recently acquired T. gondii infection in India.

  • Oral hairy leukoplakia occurs on the lateral surface of the tongue that clinically as an asymptomatic white lesion. It is mainly found in patient with human immunodeficiency virus infection. However, it rarely outbreak immunosuppressed patients after organ transplantation, or the patients taking steroids or immunosuppressants. It is the result of proliferating Epstein-Barr virus in the oral epithelium. Most of human immunodeficiency virus infected patients with oral hairy leukoplakia are highly contagious and possible to progress acquired immunodeficiency syndrome. Therefore, the early diagnosis of oral hairy leukoplakia is very important. Taking a thorough history and human immunodeficiency virus screening test is highly recommended in case oral hairy leukoplakia is detected. In this case, a 29-year-old man presented with whitish lesion on lateral border of tongue is diagnosed as oral hairy leukoplakia and human immunodeficiency virus infection.

  • Achromobacter xylosoxidans is a gram-negative bacterium that can oxidize xylose. It is commonly found in contaminated soil and water but does not normally infect immunocompetent humans. We report a case of a cavitary lung lesion associated with community-acquired A. xylosoxidans infection, which mimicked pulmonary tuberculosis or lung cancer in an immunocompetent man. The patient was hospitalized due to hemoptysis, and chest computed tomography (CT) revealed a cavitary lesion in the superior segment of the left lower lobe. We performed bronchoscopy and bronchial washing, and subsequent bacterial cultures excluded pulmonary tuberculosis and identified A. xylosoxidans. We performed antibiotic sensitivity testing and treated the patient with a 6-week course of amoxicillin/clavulanate. After 2 months, follow-up chest CT revealed complete resolution of the cavitary lesion.

  • Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired immune-mediated polyneuropathy. Corticosteroids, intravenous immunoglobulin (IVIG) and plasmapheresis have been reported to be effective treatment. Rarely, CIDP can occur in the patients with HIV infection. The clinical features and electrophysiological findings of CIDP are known to be similar in patients with and without HIV infection. We report a 30-year-old male with HIV infection associated CIDP who improved after the administration of intravenous immunoglobulin and long term oral prednisone.

  • Methicillin resistant Staphylococcus aureus (MRSA) is one of the most common nosocomial pathogens. Many hospitals are facing the problems which they have to use expensive antibiotics and suffer from long term hospital study of patients due to MRSA. This study is to survey MRSA nasal colonization of patients and doctors, and to investigate the mode of transmission of MRSA by pulsed field gel electrophoresis (PFGE) and then use these data to prevent further spread of cross infection and reduce nosocomial infection. Subjects of this study were 201 patients with MRSA infection at an university hospital in Busan from Sept. 1997 to Aug. 1998. Bacterial genotypes of MRSA strains isolated from nares and wound of patients (14 cases) and nares of doctors (8 cases) were analyzed by PFGE. Nasal cultures of 20 I patients for detecting nasal colonization of MRSA were performed and incidence rate of nasal colonization was 40% (80/201). Among 201 patients MRSA were acquired from hospital in 140 (70%) patients and were acquired from community 61 (30%) patients. Among 14 pairs of MRSA from colonized or infected sites and anterior nares, DNA patterns of 10 pairs (71.4%) were equal. 86% (12/14) MRSA strains isolated from patients and 12.5% (1/8) MRSA strains isolated from doctors show same pattern. DNA patterns were changed in some doctors after nasal oint. Treatment. It could be inferred that the most sources of MRSA in hospital are the endemically existing MRSA. Therefore, we believe that it would be necessary to control MRSA nasal colonization of the patients and the related medical teams to reduce the medical cost and to improve the efficacy of medical cares.

  • It is uncommon for a palatal fistula to be detected in individuals who have not undergone surgery, and only sporadic cases have been reported. It is even more difficult to find cases of acquired palatal fistula in patients with submucous or incomplete cleft palate. Herein, we present 2 rare cases of this phenomenon. Case 1 was a patient with submucous cleft palate who acquired a palatal fistula after suffering from oral candidiasis at the age of 5 months. Case 2 was a patient with incomplete cleft palate who spontaneously, without trauma or infection, presented with a palatal fistula at the age of 9 months.

  • Increasing incidence of pleural infection has been reported worldwide in recent decades. The pathogens responsible for pleural infection are changing and differ from those in community acquired pneumonia. The main treatments for pleural infection are antibiotics and drainage of infected pleural fluid. The efficacy of intrapleural fibrinolytics remains unclear, although a recent randomized control study showed that the novel combination of tissue plasminogen activator and deoxyribonuclease had improved clinical outcomes. Surgical drainage is a critical treatment in patient with progression of sepsis and failure in tube drainage.
