Hand carriage of Candida occurs at lesser rates in hospital personnel who use antimicrobial hand disinfectant.

BACKGROUND: The hands of hospital personnel are considered to be important for colonization and infection of patients with Candida spp. The aim of this study was to evaluate the effectiveness of different hand disinfectants in reducing the carriage of Candida species on the hands of hospital personnel. METHODS: A controlled study was conducted at Duzce University School of Medicine Hospital. Eighty hospital personnel were included in the trial. Subjects were divided into 4 groups according to hand hygiene procedures: group 1, hand rubbing with alcohol-based solution; group 2, hand washing with 4% chlorhexidine gluconate; group 3, hand washing with 7.5% povidone-iodine; group 4, hand washing with plain soap and water. The hands of all participants were tested by culture with the broth wash technique. RESULTS: Hand carriage of Candida spp. was lower in the 4% chlorhexidine gluconate group (10.5%, p = 0.006), in the 7.5% povidone-iodine group (18.7%, p = 0.043), and in the alcohol-based hand rub group (21.1%, p = 0.048) compared to the group washing hands with plain soap and water (50%). CONCLUSIONS: The use of hand disinfectant containing antimicrobial agents is more effective than hand washing with water and soap in reducing carriage of Candida on the hands of hospital personnel. It is recommended that hospital personnel use an antimicrobial hand disinfectant in units where there is a high risk of Candida infection.

Effects of cruroraphy and laparoscopic Nissen fundoplication procedures on pulmonary function tests in gastroesophageal reflux patients.

Gastroesophageal reflux disease plays a role in the etiology of asthma, chronic bronchitis, aspiration pneumonia, bronchiectasis and interstitial lung fibrosis by affecting the upper respiratory system. To investigate the changes in pulmonary function tests in patients who underwent cruroraphy and laparoscopic Nissen fundoplication for gastroesophageal reflux disease. Between January and October of 2012, cruroraphy and laparoscopic Nissen fundoplication have been carried out on 40 patients with gastroesophageal reflux disease in the Department of General Surgery, Faculty of Medicine, Duzce University. Patients had pulmonary function tests were measured preoperatively and on postoperative day 20. Increases in forced vital capacity, forced expiratory volume in 1 second/forced vital capacity and forced expiratory flow between 25-75% of vital capacity were observed postoperatively in all patients and these increases were found to be statistically significant (p=0.001). Change in the forced expiratory volume in 1 second was not statistically significant (p=0.182). We conclude that treatment of reflux in early stages by surgical procedures could prevent development of chronic lung disease by safeguarding the pulmonary system functions.

[Investigation of the effects of probiotic bacteria on bacterial translocation that developed during diagnostic laparoscopy: an experimental study]. / Tanisal Amaçla Uygulanan Laparoskopi Sirasinda Olusan Bakteriyel Translokasyona Probiyotik Bakterilerin Etkilerinin Arastirilmasi: Deneysel Bir Çalisma.

Probiotics which are non-pathogenic live microorganisms ingested along with food or as dietary supplements, are thought to be beneficial to the host by supporting the microbial balance in digestive system. Various studies suggest that the effects of probiotics on the intestinal mucosa and immunity are protective against bacterial translocation. We aimed to investigate bacterial translocation related to the amount of CO2 insufflation given during laparoscopy and the effect of probiotic bacteria in an experimental peritonitis model. In this study 60 Wistar rats were used in six groups consisting of 10 rats. Group 1, 3 and 5 consisted of the rats that were fed without probiotics, while the rats in Group 2, 4, and 6 were fed with water containing 5 x 108 cfu/ml probiotic bacteria complex (Bifidobacterium lactis, Lactobacillus bulgaricus, Streptococcus thermophilus) for 15 days. To generate experimental peritonitis, 2 x 107 cfu/ml Escherichia coli ATCC 25922 was inoculated intraperitoneally to all of the rats. Thereafter, laparoscopy was applied in all groups. Application in Group 1 and Group 2 was without CO2; Group 3 and Group 4 with 14 mmHg CO2 insufflation, and Group 5 and Group 6 with 20 mmHg CO2 insufflation. Blood samples were taken in 2nd, 4th, and 6th hours. Mesenteric lymph node, liver and spleen samples were taken at 6th hour when the rats were sacrificed and then these were evaluated microbiologically with qualitative and quantitative methods. Bacterial translocation and bacteremia were found in the rats that were undergone experimental peritonitis during laparoscopy. All positive tissue and blood cultures yielded E.coli. The highest level of bacterial translocation was found to be in mesenteric lymph nodes (in 3/10, 6/10 and 10/10 in groups 1, 3 and 5 fed without probiotics, respectively; in 2/10, 3/10 and 4/10 in groups 2, 4 and 6 fed with probiotics, respectively). The bacterial translocation rates were found to be related to the increased CO2 insufflation. It was found that probiotic bacteria were more effective for decreasing bacterial translocation rates and bacteremia in the groups that were given high CO2 pressure during laparoscopy. It was also found that these results were correlated with bacterial translocation per gram of tissue. As an example, the quantitative bacterial growth values detected in mesenteric lymph node were 5.4 ± 2.9 x 103, 10.6 ± 3.3 x 103 and 21.5 ± 12.4 x 103 cfu/g in groups 1, 3 and 5, fed without probiotics, respectively; and 2.0 ± 1.3 x 103, 3.8 ± 1.9 x 103 and 9.0 ± 3.1 x 103 cfu/g in groups 2, 4 and 6, fed with probiotics, respectively. Our data emphasized that probiotic bacteria may be used as prophylactic agents for the prevention of bacterial translocation during laparoscopy, however comprehensive and clinical studies are needed to support these experimental results.

Primary echinococcus cyst of the thyroid: a case report.

Echinococcosis, although eradicated in many countries, is still widespread in communities where agriculture is dominant. Cystic hydatidosis is a significant public health problem in the regions with endemic echinococcosis. The hydatid cysts tend to form in the liver or lung, but may also be found in other organs of the body such as brain, heart, and bone, while thyroid gland involvement is rather rare. A 25 year old male presented with solitaire goiter. Laboratory tests and thyroid profile proved normal. Surgical exploration revealed hydatid cyst in the left lobe of the thyroid gland. Examination of the nodule showed it to be a solitary primary thyroid hydatid cyst.

Changing patterns of hepatitis A and E sero-prevalences in children after the 1999 earthquakes in Duzce, Turkey.

AIM: Hepatitis A and E are enteric viral diseases that are characteristically found in developing countries. Sero-epidemiological data about both infections showed higher prevalence rates soon after the 1999 earthquakes in Duzce, Turkey. The aim of the present study was to evaluate the data 4 years after the earthquakes. METHODS: The study group included 589 children (72.3% boys) who were between the ages of 6 months and 17 years (mean age 11.5 years). The children were separated into three groups: Group 1 (ages 6 months to 5.9 years), Group 2 (ages 6.0-12.9 years) and Group 3 (ages 13.0-17.0 years). Serum anti-hepatitis A virus IgG and anti-hepatitis E virus IgG were determined using commercial enzyme-linked immunosorbent assay kits. The data were tested for statistical significance with the chi(2)-test. RESULTS: The sero-prevalence rates of hepatitis A and E were 63.8% and 0.3%, respectively. The sero-prevalence rates of both hepatitis A and E increased with age, and there was no significant difference between the genders. Hepatitis A infection was associated with socio-economic condition, crowded living environment, and education level of the family (P < 0.01). CONCLUSIONS: Hepatitis A infection is still common, whereas hepatitis E infection appears to be relatively rare in paediatric age groups in Duzce, Turkey.
