Vascular graft infection by Staphylococcus aureus: efficacy of cefazolin, teicoplanin and vancomycin prophylaxis protocols in a rat model.

OBJECTIVES: Prophylactic efficiencies of cefazolin, teicoplanin and vancomycin in a dacron graft infection model caused by methicillin-susceptible (MSSA) or -resistant Staphylococcus aureus (MRSA) were investigated. DESIGN: Prospective, randomized, controlled animal study. MATERIALS AND METHODS: Infections were established subcutaneously in the back of rats by implantation of Dacron prostheses followed by topical inoculation onto grafts of MSSA or MRSA. Experimental groups were as follows: Uncontaminated group (control), MSSA- or MRSA-contaminated and untreated groups, MSSA- or MRSA-contaminated groups treated with cefazolin, teicoplanin or vancomycin by one of three regimens (one day, two days, or three days regimen). Grafts were removed 7 days after the implantation and evaluated by using sonication and quantitative blood agar culture. RESULTS: Contaminated groups demonstrated graft infections. Cefazolin, teicoplanin and vancomycin profoundly prevented the graft infections in MSSA- or MRSA-contaminated groups. For each antibiotic regimen, the most effective prevention was achieved by the drugs given as three days regimen. For MSSA and MRSA, the order of the effectiveness was as follows: teicoplanin>vancomycin>cefazolin. CONCLUSION: As a prophylactic agent, teicoplanin seems to be more effective than vancomycin and cefazolin against vascular graft infections caused by MSSA and MRSA in rats.     

Mortality from asthma in children and young adults in Louisiana.

BACKGROUND: Asthma mortality rates have been increasing despite our improved understanding of the pathophysiology of asthma and advanced methods of treatment. Although there are many national studies of asthma mortality rates, few studies have concentrated on subnational regions such as individual states. OBJECTIVES: We sought to determine the trends in asthma mortality in children and young adults during the last 15 years in Louisiana. METHODS: Asthma mortality data were acquired from the Louisiana State Center for Health Statistics for the years 1983 through 1997. All asthma deaths coded International Classification of Disease, Ninth Revision 493 were included in the data set along with year, sex, and rate characteristics. State population estimates obtained from the United States Bureau of Census for three 5-year periods (1983 to 1987, 1988 to 1992, and 1993 to 1997) were used to calculate crude and adjusted mortality rates. These time periods were compared with one another and with the period 1983 to 1987, which was used as a baseline. RESULTS: For all residents, the mortality rate increased from 0.41 deaths per 100,000 persons during the 1983 to 1987 time period to 0.49 and 0.63 deaths per 100,000 persons during 1988 to 1992 and 1993 to 1997 time periods, respectively. Mortality rates have increased in both the white and non-white populations over the 15-year study period, with the most pronounced increases among the non-white population. CONCLUSION: Asthma mortality rates in Louisiana have increased, particularly among the non-white population, over the last 15 years, although the results are not statistically significant. When compared with other states, asthma mortality in Louisiana is lower than in the northeast and central north states.     

Causes of increased renal medullary echogenicity in Turkish children

The primary disorders of 50 children with increased renal medullary echogenicity on renal ultrasound were studied; 28 girls and 22 boys aged from 1 month to 16 years were classified into four groups based on underlying disease and ultrasound findings. Group 1 was composed of 17 patients with distal renal tubular acidosis (34%); intense echoes throughout the pyramid were predominant. Group 2 consisted of 14 patients with vitamin D toxicity (28%) and an intense echogenic rim around the pyramids. Group 3 included 10 patients with different types of tubulopathies. A slight hyperechogenic rim around the sides and tip of the medullary pyramids was detected. Group 4 was made up of 9 patients with rare underlying conditions. Abdominal X-rays detected medullary calcinosis in only 12 (24%) of the total 50 patients. Ultrasonography appears to be an important tool in the early diagnosis of increased renal medullary echogenicity and medullary nephrocalcinosis.     

Hereditary pancreatitis: Report of a family from Turkey

Chronic pancreatitis is a rare disease in children and is usually secondary to underlying diseases such as hereditary pancreatitis, cystic fibrosis, hyperlipidemia, prolonged malnutrition, gallstones or anomalies of the biliary-pancreatic duct system. Hereditary pancreatitis is a common cause of chronic pancreatitis in children but is often unrecognized until months or years later. We report here a family with hereditary pancreatitis in which four members are affected.     

Trauma-related oral lesions; Angina bullosa haemorrhagica: a rare case presentation

Angina bullosa haemorrhgica is a relatively uncommon condition characterized by blood-filled subepithelial lesions in the oral mucosa that is idiopathic and not caused by a systemic disease or a hemostatic abnormality. Middle-aged and elderly patients are usually affected and lesions heal spontaneously without scarring. A rapidly expanding hemorrhagic blister in the oropharynx can induce upper airway obstruction, so recognizing the lesion as soon as possible is essential. Because of its rarity, we wanted to highlight a 42-year-old male patient who presented with hemorrhagic bullae associated with insignificant local trauma in the oral mucosa and to emphasize that Angina bullosa haemorrhagica is a rare but recognizable lesion that clinicians should be aware of.     

The effect of education given to type 2 diabetic individuals on diabetes self-management and self-efficacy: Randomized controlled trial

AimThis study used a randomized controlled trial design and was carried out to examine the effect of education on diabetes self-management and self-efficacy in patients with type 2 diabetes.MethodsThe study was carried out between July 2016–March 2017. Data were collected using information form, Diabetes Self-Management Questionnaire (DSMQ), self-efficacy scale for patients with type 2 diabetes (DSS).The individuals in the experimental group were given education. Both groups were reminded about the control time of their metabolic values on the phone in the 3rd and 6th months.ResultsThe average age of the individuals was 59.91 ± 8.93 (n = 78), 62.8% (n = 49) were female, 92.3% (n = 72), were married, 42.3% (n = 33) were high school graduates and their diabetes duration was 7.05 ± 3.9. There was a statistically significant difference in the 6th month metabolic values in the experimental group compared to the control group. When diabetes self-management and self-efficacy were examined, a statistically significant difference was found in the experimental group compared to the control group at 3rd and 6th months (p < 0.05, p < 0.01).ConclusionIn this study, a significant increase in diabetes self-management and self-efficacy and a significant decrease in metabolic values were observed as a result of education and phone reminders given to individuals with type 2 diabetes.     

Causes of acute poisoning in adults: a retrospective study, in a hospital in Istanbul, Turkey

Aim  

Acute poisoning is one of the major topics in emergency medicine practices. Despite the recent developments in toxicology, technological advances and changing lifestyles reveal new factors, and poisoning cases remain to be a problem. All poisonings should be considered serious and independent from their clinical presentation at the time of admission. Identifying the cause and prompt initiation of treatment is life-saving. Causes of poisoning vary between countries and different regions of the same country. In the present study, cases admitted to the Emergency Department of Internal Medicine at Haseki Training and Research Hospital were evaluated and causes of acute poisoning were investigated.
