Treatment of two postoperative endophthalmitis cases due to <Emphasis Type="Italic">Aspergillus flavus</Emphasis> and <Emphasis Type="Italic">Scopulariopsis</Emphasis> spp. with local and systemic antifungal therapy

Background  

Endophthalmitis is the inflammatory response to invasion of the eye with bacteria or fungi. The incidence of endophthalmitis after cataract surgery varies between 0.072–0.13 percent. Treatment of endophthalmitis with fungal etiology is difficult.     

The distribution of HLA-DRB alleles in ulcerative colitis patients in Turkey

Recently described distinct associations of HLA class II genes with ulcerative colitis (UC) suggest a genetic heterogeneity for disease susceptibility. In this study, HLA-DRB alleles of UC patients (n = 59) from Turkey were investigated and compared with healthy controls (n = 244). Using molecular genotyping by polymerase chain reaction (PCR) and sequence-specific oligonucleotide hybridization, we have shown a positive association of UC patients with the HLA-DRB1*1502 allele (10/59 vs. 16/244; P = 0.02; OR: 2.9) and a negative association with the DRB1*13 allele (7/59 vs. 64/244; P = 0.03; OR: 0.38) compared to controls. HLA-DRB1*0701 was significantly increased in perinuclear antineutrophil cytoplasmic antibody (pANCA)-positive UC patients compared to pANCA-negative patients (8/32 vs. 0/27; P = 0.005), whereas DRB1*1502 was observed more frequently in pANCA-negative patients (8/27 vs. 2/32; P = 0.03). These results extended the reported positive association of DRB1*1502 with UC to another population and supported the genetic susceptibility associated with HLA genes for disease development.     

Molecular analysis of HLA-DRB1, -DQA1 and -DQB1 polymorphism in Turkey

We report the evaluation of MHC class II polymorphism in the population of Turkey. HLA-DRB1, -DQA1 and -DQB1 have been investigated by polymerase chain reaction and sequence-specific oligonucleotide probe hybridisations (PCR/SSO) and sequence-specific priming (SSP) in 250 randomly selected healthy individuals. We also report the allelic distribution of these genes. The most frequent alleles detected were DRB1*1101 (0.104), *0301 (0.092), *0701 (0.090), DQA1*0501 (0.334), *0102 (0.164) and *03 (0.148) and DQB1*0301 (0.256), *02 (0.164), *0302 (0.128). The frequent 'putative' three-locus haplotypes carry the most frequent alleles at these loci. The most frequently detected class II "haplotypes" are DRB1*1101 DQA1*0501 DQB1*0301 (0.100), DRB1*0301 DQA1*0501 DQB1*02 (0.092) and DRB1*0701 DQA1*0201 DQB1*02 (0.072). The distribution of alleles and 'putative' haplotypes has shown common features with other Mediterranean populations. The results extend the HLA map to another Mediterranean country and provide a database for further HLA-disease association studies and transplantation applications.     

Laryngopyocele: signs on computed tomography

A laryngocele is an air-filled dilation of the saccule of the larynx. An infected laryngocele is called a laryngopyocele. Our experience with a case of laryngopyocele with signs on computed tomography before and after antibiotic therapy is presented since laryngopyocele is more unusual.

Eosinophilic colitis in a patient with advanced transitional cell carcinoma of the bladder: a paraneoplastic syndrome?

Eosinophilia associated with tumors is extremely rare. The exact underlying pathogenetic mechanisms are not well understood; limited data have been reported about granulocyte colony-stimulating factor and interleukin-5 in the development of eosinophilia. We report a patient with marked eosinophilia, leukocytosis, and eosinophilic colitis presenting with bloody stool. The subsequent diagnosis was advanced high-grade transitional cell carcinoma of the bladder. Leukocyte count, eosinophil count, and colonoscopic findings returned to normal after surgical removal of the tumor. To our knowledge, eosinophilic colonic infiltration as a manifestation of transitional cell bladder carcinoma has not been previously reported.

Body Composition Analysis of Patients on Waiting List for Cadaveric Renal Transplantation: A Comparison of Hemodialysis and Peritoneal Dialysis Patients

BackgroundBioelectrical impedance analysis is a simple, noninvasive method of assessing body composition. Dialysis modality and selection of buffer type may have an impact on body composition. The aim of our study was to compare body compositions of patients from the waiting list for cadaveric renal transplantation according to the dialysis modality.MethodsWe examined a total of 152 (110 hemodialysis [HD] and 42 continuous ambulatory peritoneal dialysis [CAPD]) patients. Demographic data were collected from patient charts. The last 6 months routine laboratory evaluations including hemoglobin, serum creatinine, intact parathyroid hormone, albumin, C reactive protein, calcium, phosphorus were collected. Body compositions were measured using the Tanita BC-420MA Body Composition Analyzer (Tanita, Tokyo, Japan). We made a subanalysis of the CAPD group according to buffer choices as follows: lactate-buffered (n = 16) and bicarbonate/lactate–buffered (n = 26) solution users.ResultsThe body weight (P = .022), body mass index (BMI; 25.8 ± 4.7 vs 23.4 ± 4.9 kg/m², P = .009), muscle mass (P = .01), fat-free mass (P = .013), and visceral fat ratio (9.5 ± 5.4 vs 7.3 ± 4.1 %, P = .022) were significantly higher in the CAPD group. Total body water of CAPD patients were also higher (P = .003), but total body water ratios of HD and CAPD groups were similar. Fat and fat-free mass ratios of patient groups were also similar. Comparing CAPD subgroups we observed that patients using bicarbonate/lactate–buffered solutions had higher body weights (P = .038), BMI (27.1 ± 5 vs 23.7 ± 3.5 kg/m², P = .018) values, and visceral fat ratios (8.0 ± 5.2 vs 4.6 ± 2.5 %, P = .023). These patients also tend to have higher fat mass without statistical significance (P = .074). Fat, muscle, and fat-free mass total body water ratios of peritoneal dialysis subgroups were similar.ConclusionWe believe that body composition analysis should be used as a complementary method for assessing nutritional status of PD and CAPD patients as body weight or BMI measurements do not reflect fat, muscle masses, and visceral fat ratios in these patients. Stable, well nourished CAPD patients should be closely observed and be encouraged to increase daily exercise and/or decrease calorie intake from other sources to decrease risks associated with abdominal obesity.
