Scedosporium apiospermum chorioretinitis

PURPOSE: A case of a 24-year-old immunocompetent woman who developed unilateral Scedosporium apiospermum chorioretinitis and diffuse cervical lymphadenitis 10 years after facial steroid injection is described. METHODS: The patient was initially treated for the misdiagnosis of tuberculous lymphadenitis. Contemporaneous to the enlargement of her lymph nodes, she experienced gradual loss of vision in her left eye. She subsequently underwent lymph node biopsy. RESULTS: Histopathologic sections stained with Grocott's methenamine silver showed branched septate hyphae and cultures on Sabouraud's agar yielded Scedosporium apiospermum. The patient received oral itraconazole 200 mg twice daily. Lymphadenitis regressed within a year and chorioretinitis scarred within two years. CONCLUSION: Scedosporium apiospermum may cause isolated chorioretinitis in an immunocompetent individual years after local surgery or trauma and result in significant visual morbidity. Treatment may require prolonged use of systemic itraconazole.     

A comparison of four disability scales for Turkish patients with neck pain.

OBJECTIVE: The Neck Disability Index, the Northwick Park Pain Questionnaire, the Copenhagen Neck Functional Disability Scale and the Neck Pain and Disability Scale are widely used scales for assessing neck pain or disability. The aim of this study was to determine the most suitable scale for Turkish patients with neck pain. METHODS: All scales were translated into Turkish, administered to 102 patients with neck pain, then compared with regard to their construct validity, reliability, responsiveness, acceptability and usefulness. RESULTS: The scales were similar in their high validity, reliability standards and sensitivity to change, but differed in their acceptability and usefulness. The item about driving in the Neck Disability Index and the Northwick Park Pain Questionnaire was omitted by 69.6% of patients for reasons other than a neck problem. CONCLUSION: All scales were reliable, valid and sensitive instruments, with similar psychometric properties. The scale that most adequately reflects the patient should be chosen.     

Portomesenteric venous gas: imaging findings with an emphasis on sonography.

OBJECTIVE: Portomesenteric venous gas is a rare condition with an unclear pathogenesis. Most studies in the medical literature mention computed tomography (CT) as the primary imaging tool for this entity. The objective of this study was to outline the advantages and disadvantages of sonography in the evaluation of patients with portomesenteric venous gas. METHODS: We describe 7 patients (3 female and 4 male; age range, 47-83 years) with portomesenteric venous gas. Both CT and sonographic examinations were performed in each patient. Our patient population consisted of 2 patients with superior mesenteric artery occlusion, 3 with ischemia of the colon, small bowel, or both, 1 with gastric ulcer perforation, and 1 with ischemic bowel disease presumably secondary to complications of continuous ambulatory peritoneal dialysis. RESULTS: Portal venous gas was observed in all 7 patients with sonography and in 6 patients with CT. Computed tomography was unable to show gas in the portal venous system in 1 patient. Sonography showed patchy hepatic gas accumulation (likely within small peripheral portal vein branches) with no correlative findings on CT. Computed tomography showed important associated findings, including pneumatosis intestinalis. CONCLUSIONS: In cases with portomesenteric gas, CT is the preferred modality for showing the underlying etiology. However, with its real-time imaging capability, sonography may also be a very valuable imaging modality in the evaluation of this entity.     

Multicenter evaluation of AYC.2.2 agar for the isolation of mycobacteria from clinical samples

PurposeThe aim of this multicenter study is to evaluate AYC.2.2 agar for the isolation of mycobacteria from clinical samples.MethodsTotally 5559 media were tested in 7 centers. AYC.2.2 agar media for the study were prepared by C1 and sent to other centers under appropriate conditions. Other media except AYC.2.2 agar were purchased commercially.The media were subjected to routine laboratory operations in the center where they were sent. After the samples received for routine processing (in all centers, samples were processed with the same method (NALC-NaOH)), they were cultivated on routine media and AYC.2.2 agar afterward.ResultsC1: Average growth time was determined as 12.74±3.74 days with MGIT 960 system; 24.42±4.75 days with LJ and 24.37±4.96 days with AYC.2.2 agar. C2: Average growth time was determined as 18.25±9.32 days with TK-Medium, 28.73±7.44 days with LJ, and 31.72±6.35 days with AYC.2.2 agar. C3: Average growth time was determined as 20.48±7.24 days with Ogawa medium, 20.74±7.12 days with LJ, and 20.26±7.43 days with AYC.2.2 agar. C4: Average growth time was determined as 15.27±6.37 days with MGIT 960 system, 22.14±9.1 days with LJ, and 22±8.45 days with AYC.2.2 agar. C5: Average growth time was determined as 13±4.24 days with MGIT 960 system, 32.16±6.23 days with LJ, and 33±5.73 days with AYC.2.2 agar. C6: Average growth time was determined as 9±3.11 days with MGIT 960 system, 18.68±5.32 days with LJ, and 18.34±4.63 days AYC.2.2 agar. C7: Average growth time was determined as 14.74±7.65 with MGIT 960 system, 26.01±8.21 days with LJ, and 26.24±7.88 days with AYC.2.2 agar.ConclusionsIn conclusion, similar results were obtained with LJ and Ogawa media and AYC.2.2 agar. Furthermore, more studies should be conducted for isolation of M. tuberculosis and performing antibiotic susceptibility tests using AYC.2.2 agar before it can be used as a routine media in the laboratories.     

Screening of Tissue Transglutaminase Antibody in Healthy Blood Donors for Celiac Disease Screening in the Turkish Population

Celiac disease (CD) is a disease having the characteristic pathology of the mucosa of the small intestine. The prevalence of CD in the Turkish population has not been investigated previously. The present study was designed to determine the prevalence of CD in healthy blood donors. Serum samples of 2000 healthy blood donors presenting to Hacettepe University Faculty of Medicine Hospital Blood Bank were tested for tissue transglutaminase (tTG) IgA and IgG antibodies with enzyme-linked immunosorbent assay (ELISA; Euroimmune, Germany). The histopathological findings for the cases with positive serology were evaluated. The distribution of sex was 95.7% male, and 4.3% female. The mean age was 33 +/- 9. Among 2000 donors, 23 (1.15%) were positive for tTG IgA antibody and 3 (0.15%) were positive for tTG IgG antibody. None of the samples was positive for both antibodies. Serum total IgA was measured in two cases with only tTG IgG positivity and was found to be low in one case. Twelve subjects positive for tTG agreed to endoscopy and biopsy. Histopathological examination revealed changes classified as Marsh III-II in one, Marsh II in two, Marsh I in seven, and Marsh 0 in two donors. This was the first study conducted to determine the prevalence of tTG positivity in the Turkish population. The tTG antibody positivity prevalence in healthy blood donors was as high as 1.3%. This study shows that the prevalence of CD in the Turkish population is relatively high in comparison to that in the Western world.     

Antifungal Activity of Propolis Against Yeasts Isolated From Blood Culture: In Vitro Evaluation

Background: Due to the failure of available antifungal agents in the treatment of candidemia and the toxic activities of these drugs, a lot of researches are being conducted to develop new nontoxic and effective antifungal agents for optimal control of fungal pathogens. The aim of this study is to evaluate the in vitro antifungal activity of propolis against yeasts isolated from the blood cultures of intensive care unit patients. Methods: Seventy‐six strains were included in this study. The in vitro antifungal activity of propolis, fluconazole (FLU), and itraconazole (ITR) was investigated by the microdilution broth methods (CLSI guidelines M27‐A3 for yeast). The propolis sample was collected from Kayseri, Turkey. Results: Of the 76 isolates, 33 were identified as Candida albicans while 37 were C. parapsilosis, three were C. tropicalis, and three were identified as C. glabrata. The geometric mean range for MIC (μg/ml) with regard to all isolates was 0.077 to 3 μg/ml for FLU and ITR, and 0.375 to 0.70 μg/ml for propolis. It was shown that propolis had significant antifungal activity against all Candida strains and the MIC range of propolis was determined as 0185 to 3 μg/ml. Conclusion: This study demonstrated that propolis had significant antifungal activity against yeasts isolated from blood culture compared with FLU and ITR. The propolis MIC in azole‐resistant strains such as C. glabrata was found lower than the FLU MIC.
