Analysis of workplace health and safety, job stress, interpersonal conflict, and turnover intention: a comparative study in the health sector.

BACKGROUND: This study aims to examine the relationship between workplace health, job stress, turnover intention and interpersonal conflict in the health sector. It also seeks to unravel how the public and private working environment, and demographic variables affect those four variables. PARTICIPANTS AND PROCEDURE: A cross-sectional survey design was used for this study. The respondents were selected based on simple random sampling. Out of 1000 questionnaires administered, 708 were returned (432 from public hospitals and 276 from private hospitals) and used. Correlation, multiple regression, and ANOVA analysis were used to determine the relationship and impact between the variables. RESULTS: The findings revealed negative and significant relationships between workplace health and safety and stress, turnover intention and interpersonal conflict. Additionally, some results reflected the significant positive relationship between stress, turnover intention and interpersonal conflict. Finally, turnover intention, job stress, education level and number of duties accounted for 30% of the variation in workplace health and safety. CONCLUSIONS: Managers within the healthcare sector of Turkey should acknowledge that workers who do not feel healthy and safe in work environments develop high stress, turnover intention, and conflict with other colleagues.

Factors influencing insulin usage among type 2 diabetes mellitus patients: A study in Turkish primary care.

BACKGROUND: DM (diabetes mellitus) patients with poorly regulated blood glucose levels are at risk of increased morbidity and mortality. There are different factors that cause resistance to the initiation of insulin therapy such as beliefs and perceptions concerning diabetes and its treatment and the nature and consequences of insulin therapy. OBJECTIVES: We aimed to explore the reasons for this reluctance and how these obstacles could be overcome so that DM patients who require insulin could initiate therapy. METHODS: This was a cross-sectional, descriptive study of diabetic patients with glycated haemoglobin A1c (HbA1C) levels above 7.0%, who were followed-up at a primary care and endocrinology outpatient clinic. RESULTS: Ninety-four patients (57.4% females, 42.6% males) were recruited for this study. Most patients (57.4%) considered that insulin was a drug of last resort. Among all patients, 34.1% thought that insulin lowered blood glucose levels to an extreme degree and 14.9% disagreed. The patients thought that self-injection was hard (27.6%), required someone else to administer the injection (27.6%), insulin injection was painful (33.0%). 59.6% of all patients believed that their religion did not restrict the use of insulin, 52.1% stated that their family physicians had sufficiently informed them. CONCLUSION: Our most significant finding is that a lack of adequate information relating to insulin appears to be the major factor behind DM patients' refusal of insulin treatment. The fact that patients consider insulin treatment as a final solution to DM could be related to resistance to the initiation of insulin therapy. [Box: see text].

The effects of nosocomial rotavirus gastroenteritis on the length of hospital stay and cost.

INTRODUCTION: In this study, the goal was to evaluate the impact of nosocomial rotavirus gastroenteritis in pediatric patients by determining the incidence of nosocomial rotavirus gastroenteritis, the resulting duration of hospital stay, and direct cost. To our knowledge, this is the first study in Turkey that evaluates the impact of pediatric nosocomial rotavirus gastroenteritis on duration of hospital stay and calculates the direct cost. METHODOLOGY: Forty-nine patients who were diagnosed with nosocomial rotavirus gastroenteritis and hospitalized were included in the study. Nosocomial infection rates, organ systems affected by the nosocomial infections, and patients who had nosocomial rotavirus gastroenteritis were identified. A direct cost analysis of patients who were diagnosed with nosocomial rotavirus gastroenteritis was performed using copies of the invoices for the hospital bills. RESULTS: During the study period, there were 49 cases of nosocomial rotavirus gastroenteritis. The length of hospitalization was extended, on average, by more than 6.3 days in cases of nosocomial rotavirus gastroenteritis. The cost of hospitalization for patients with nosocomial rotavirus gastroenteritis was on average 1,554 ± 2,067 US dollars, compared to a cost of only 244 ± 103 US dollars for patients who did not have nosocomial rotavirus gastroenteritis. This difference in cost was statistically significant (p < 0.05). CONCLUSIONS: Nosocomial rotavirus gastroenteritis is important because it significantly prolongs hospital stay and increases the social and economic burden of the hospitalization. Nosocomial rotavirus gastroenteritis can be reduced with prevention measures such as handwashing, isolation, and cohorting.

Relationship between hepcidin levels and periodic limb movement disorder in patients with obstructive sleep apnea syndrome.

PURPOSE: This study was aimed to assess potential correlations between periodic leg movement (PLM) index, hepcidin levels, and iron status in patients with obstructive sleep apnea syndrome (OSAS). METHODS: Forty-four newly diagnosed OSAS patients and 49 non-apneic controls were enrolled in this study. All patients underwent polysomnographic evaluation. The hepcidin, iron, ferritin, total iron binding capacity, and C-reactive protein levels were measured. RESULTS: The mean age was 47.4 ± 7.2 years (18-68) in the OSAS group and 44.9 ± 11.1 years (23-65) in the control group. There were no differences in age, gender, and smoking between OSAS patients and controls. Mean apnea-hypopnea index (AHI) was 25.1 events/h. Mean serum hepcidin levels were significantly higher in OSAS subjects (725.9 ng/ml) than in control subjects (646.0 ng/ml) (p < 0.001). Serum iron levels were significantly lower in the OSAS and PLM disorder groups than in control subjects (p < 0.001). Serum hepcidin levels were significantly correlated with AHI (r = 0.453) and PLM index (r = 0.114). Serum iron levels were significantly negatively correlated with AHI (r = -0.169) and PLM index (r = -0.180). CONCLUSIONS: In our study, the level of hepcidin was increased in patients with OSAS. Our study indicates that levels of hepcidin correlate with the AHI and PLM index severity of OSAS.

A microbiological assessment of the oral hygiene of 24-72-month-old kindergarten children and disinfection of their toothbrushes.

BACKGROUND: The objective of this study is to assess the index of decayed, missing and filled teeth (DMF-T), habit of brushing teeth, and the microbiological agents accumulating on the children's toothbrushes for 4 weeks and response of these agents to disinfection via a chlorhexidine solution, then compare those results with the education and income levels of the children's parents. METHOD: Included in the study were 187 children (96 in the control group and 91 in the experiment group - chlorhexidine) chosen randomly from 600 kindergarten children whose ages ranged from 24 months to 72 months. The children selected had not taken any antibiotics, antimicotics for three months and dental treatments during this trial. The distribution of these children to the groups was also done randomly. After performing a survey for the education, occupation, and income status of the parents, the children were examined and the number of decayed teeth was recorded. The children were given toothbrushes, toothpaste (with fluroide), and the solutions (including distilled water and chlorhexidine) for four weeks under the condition that toothbrushes were returned at the end of each week. The 14 different microbiological agents observed as a result of the assessment of the samples taken in the first week were also included in the assessments of the samples taken over the four-week period. RESULTS: The decrease in the DMF-T index was found to be meaningful according to the differences in education, income, and occupation status of the parents. Of all the samples taken from the toothbrushes, the bacteria with the greatest rate of reproduction included Streptococcus mutans, Escherichia Coli, Pseudomonas aeuroginosa, Enterococcus spp, Staphylococcus epidermidis and Candida albicans. Except for Candida albicans, the other microorganisms taken as samples from the toothbrushes reproduced less overall. In the group using the solution with chlorhexidine, a meaningful decrease in bacterial reproduction was discovered compared to the control group. CONCLUSION: The findings of this study show that the education, occupation, and socioeconomic situations of the parents should be considered when discussing children's oral and dental health. Moreover, the study shows that disinfection of toothbrushes in order to prevent reinfection and contamination oral flora with the bacteria again is important in terms of preventive medicine and family-children health.

The value of inflammatory parameters in the prognosis of malignant mesothelioma.

OBJECTIVE: This study investigated the relationship between potential prognostic parameters that may be associated with increased inflammation and survival in patients with malignant mesothelioma (MM). METHODS: This retrospective study assessed potential prognostic parameters measured at the time of MM diagnosis. Data on asbestos exposure, histopathological subtype of MM and laboratory parameters were collected. RESULTS: In 155 patients with MM (90 male), mean survival time was 13.9 months. In univariate analysis, age ≥ 60 years and neutrophil-to-lymphocyte ratio (NLR) ≥ 3 were associated with significantly shortened median survival times. In multivariate analysis, nonepithelial subtype, red cell distribution width (RDW) ≥ 20% and NLR ≥ 3 were associated with significantly shortened median survival times. Mortality rate was increased 2.77-, 1.67- and 1.52-fold in patients with RDW ≥ 20%, NLR ≥ 3 and nonepithelial subtype, respectively. Nonepithelial subtype, white blood cell count ≥ 11 200 µl and platelet-to-lymphocyte ratio ≥ 300 at baseline were associated with a heightened NLR value. CONCLUSIONS: The NLR and RDW were significant predictive factors for MM prognosis.

Effects of enuresis nocturna on parents of affected children: case-control study.

BACKGROUND: Enuresis nocturna (EN) is a chronic medical disorder that may cause a parent to question their parenting ability and contribute to an inability to perform the parental role. The aim of the study was to investigate the effects of EN on the relationship between parents, and the effect of mood changes in the couples on the children. METHODS: Forty children with EN (group 1) were enrolled in the study, and 44 consecutive healthy children (group 2) were randomly selected from the same school. The clinical diagnosis for the patient group was based on a careful history. Spielberg's State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), and Dyadic Adjustment Scale (DAS) were applied to all parents, and the answers were recorded. RESULTS: STAI scores differed between the mothers in the two groups in terms of trait anxiety, while significant differences between the fathers in terms of both state and trait anxiety were observed. The BDI scores were similar between the two groups. The scores of dyadic consensus were lower in the mothers, while the affectional expression scores were lower in the EN study group fathers compared with controls. The total DAS scores were significantly lower in the parents of the children with EN. CONCLUSION: The parents of children with EN seem to experience increased levels of anxiety. Their desire to continue the marital relationship, the overall quality of their marital relationship and their comfort as a family may also be negatively affected by having a child with EN.

Occupational skin diseases in automotive industry workers.

CONTEXT: Studies on occupational skin diseases in workers of the automotive industry are few. AIM: To investigate the prevalence of occupational skin diseases in workers of the automotive industry. MATERIALS AND METHODS: Between September and December 2011, a total of 405 workers from the automotive repair industry in Diyarbakir were interviewed. They were active workers in the repair industry who had been employed for at least six months. Business owners, sellers of spare parts and accounting officers were not included. The employees were examined at their workplaces and the working conditions were observed. Detailed dermatological examination was performed. RESULTS: The mean age of the 405 workers who participated in the study was 27.7 ± 10.3. The mean working time of employees was 13.3 ± 10.4 years. All of the employees were male. Dermatological diseases were not detected in 144 out of 405 workers (35.6%) and at least one condition was diagnosed in 261 (64.4%). The most frequent diagnosis was callus, hyperkeratosis, clavus (27.7%), followed by nail changes (16.8%) and superficial mycoses (12.1%). Contact dermatitis was seen at a rate of 5.9%. DISCUSSION: Traumatic lesions such as hyperkeratotic lesions and nail changes were found most frequently. Traumatic lesions were common among individuals who did not use gloves. Most nail changes were localized leuconychia, a finding not reported in the studies on automotive industry workers. In accordance with the literature, irritant contact dermatitis was observed in patients with a history of atopy and who had been working for a long time. CONCLUSION: Occupational skin diseases comprise an important field in dermatology, deserving much attention. Further studies on occupational dermatology are necessary.

Evaluation of risk factors affecting hospital-acquired infections in the neurosurgery intensive care unit.

The aim of the present study was to identify nosocomial infections (NIs), and their associated risk factors, in patients treated in the neurosurgery intensive care unit (NICU) of our hospital. Patients determined to have NIs between January 2008 and December 2012 were included in the study. Each patient's age, gender, microbiological culture results, underlying conditions, type of NIs, device utilization, total parenteral nutrition, reason for hospitalization, Glasgow score, and treatment were recorded and evaluated using statistical analysis. Risk factors for NIs were analyzed with a logistic regression model. During the five-year period, 60 NI episodes were detected in 56 out of 1643 patients. The mean age of the patient population was 33.3 (1-79) years. Of the patients, 22 were female and 34 were male. The overall incidence rate (NIs/100) and incidence density (NIs /1000 days of stay) of NIs were 3.65% and 6.5/1000 patient days, respectively. Regardless of the year of surveillance, the three most commonly detected NIs were bloodstream infection, shunt infection, and ventilator-associated pneumonia. No statistically significant difference was detected between infected and uninfected patients in terms of sex, age, blood transfusions, or mannitol and steroid use (p ≥ 0.05). In the present study, Glasgow scores, the frequency of prior usage of broad-spectrum antibiotics, and NICU stay durations were significantly higher among patients with infections (p < 0.001). Univariate analysis demonstrated that a low Glasgow score, re-operation, and use of mechanical ventilation were risk factors for NIs. We identified low Glasgow coma scores, long hospital stay duration, use of wide spectrum antibiotics, mechanical ventilation, total parenteral nutrition, and re-operation as risk factors for NIs.

Critical evaluation of antimicrobial use--a Turkish university hospital example.

INTRODUCTION: Antimicrobials are being used unnecessarily for different reasons. The aims of this study were: assessment of the quality of antimicrobial use and determination of the factors related to correct use. METHOD: Antimicrobial practice at Dicle University Hospital (DUH) was evaluated with a point prevalence approach. Using a standardized data collection form, the patients' data (clinic, epidemiology, laboratory and antimicrobial use) was collected. Possible influential factors on antimicrobial use were examined. RESULTS: In the surveillance study 1,350 inpatients were evaluated; 461 (34.1%) of them were using antimicrobials for treatment and 187 (13.9%) for prophylaxis. Antimicrobial indication was found in 355 of 461 patients (77.0%), and the number of antimicrobials was 1.8 per patient in the treatment group. The most common reason for antimicrobial use was community-acquired infection (57.9%). Pneumonia (20.4%), skin and soft tissue infections (9.11%) and urinary tract infections (7.9%) were the most common infectious diseases. Positive culture results were available for 39 patients (8.5.0%) when antimicrobial treatment started. All steps of antimicrobial use were found appropriate in 243 patients (52.7%). In multivariate analyses, clinical manifestation of infection at the beginning (p <0.001), presence of leukocyte counting (p <0.001) and prescription by an infectious disease specialist were found significantly positive factors for wholly appropriate antimicrobial use. Hospitalization with a diagnosis other than infection was found a significantly negative factor for appropriate antimicrobial use (p=0.001). CONCLUSION: The quality of antimicrobial use could be improved with better clinical and laboratory diagnosis and consultation with infectious diseases specialists.

Relationship of cognitive performance with prolidase and oxidative stress in Alzheimer disease.

Glutamate excitotoxicity and oxidative stress are held responsible for the pathogenesis of Alzheimer's disease (AD). Prolidase is known to have a crucial part in the recycling of proline for collagen synthesis. Elevated proline levels have been shown to increase glutamate concentration. To our knowledge, prolidase activity in AD has not yet been studied. In this study, we aimed to reveal the relationship of AD with oxidative stress and collagen turnover by comparing AD patients and healthy control group with regard to total antioxidant status (TAS), total oxidant status (TOS), and prolidase levels. Fifty patients (mean age, 72.5 ± 8.9 years) diagnosed with AD and a control group comprised of 39 healthy individuals (mean age, 69.1 ± 7.1 years) were compared relative to serum TAS, TOS, and prolidase levels. The relationship of cognitive performance with prolidase, TAS, and TOS was evaluated by Mini mental state examination (MMSE). Alzheimer's disease group demonstrated statistically significantly higher prolidase and TOS levels as compared to the control group (p = 0.01, p = 0.018, respectively). Total antioxidant status level was significantly lower in the dementia group than in the control group (p = 0.032). MMSE manifested a negative correlation with prolidase and TOS levels (p = 0.001, r = -0.33; p = 0.002, r = -0.32, respectively), while displaying a positive correlation with TAS levels (p = 0.002, r = 0.32). In conclusion, elevated prolidase and TOS levels along with reduced TAS concentrations suggest that oxidative stress and collagen breakdown are involved in the cognitive impairment in AD.

Amblyopia and refractive errors among school-aged children with low socioeconomic status in southeastern Turkey.

PURPOSE: To investigate the prevalence of refractive errors and other eye diseases, incidence and types of amblyopia in school-aged children, and their relation to gender, age, parental education, and socioeconomic factors. METHODS: A total of 21,062 children 6 to 14 years old were screened. The examination included visual acuity measurements and ocular motility evaluation. Autorefraction under cycloplegia and examination of the external eye, anterior segment, media, and fundus were performed. RESULTS: There were 11,118 females and 9,944 males. The average age was 10.56 ± 3.59 years. When all of the children were evaluated, 3.2% had myopia and 5.9% had hyperopia. Astigmatism 0.50 D or greater was present in 14.3% of children. Myopia was associated with older age, female gender, and higher parental education. Hyperopia was inversely proportional with older age. Spectacles were needed in 4,476 (22.7%) children with refractive errors, and 10.6% of children were unaware of their spectacle needs. Amblyopia was detected in 2.6% of all children. The most common causes of amblyopia were anisometropia (1.2%) and strabismus (0.9%). CONCLUSION: Visual impairment is a common disorder in school-aged children. Eye health screening programs are beneficial in early detection and proper treatment of refractive errors.

Prevalence of enuresis nocturna among a group of primary school children living in Diyarbakir.

OBJECTIVE: In this study, the prevalence of enuresis nocturna (EN) was investigated among primary school children living in Diyarbakir. MATERIAL AND METHODS: Five primary schools in the center of Diyarbakir and a village primary school were selected randomly. Four thousand and five hundred self-administered questionnaires were distributed to parents; 4300 were returned, and 4203 of these questionnaires were included in this study. RESULTS: Of the children participating in the study, 52.2% of them were boys and 47.8% of them were girls. The mean age of the children was 8.66±1.61 (6-15) years, and the mean number of siblings was 4.03±2.06 (0-13). The prevalence of nocturnal enuresis was determined to be 25.9% (1087) among 4203 children, and it was more common in boys than in girls (27.8 and 23.7%, respectively). The rate of a positive family history in the nocturnal enuresis, and nonenuretic groups were 64.8, and 35.2%, respectively. The average number of siblings in the enuretic, and nonenuretic groups were 4.49±2.65, and 3.87±2.57, respectively Socioeconomic level of the families of enuretic children was worse than that of nonenuretic children. Enuretic children had episodes of bedwetting (92.3%) during night hours or both day and night (8.7 %).The number of bed wetting incidents per week was 4.1±2.2. A minority (5.7%) of the families believed that the condition resolved without any treatment. CONCLUSION: Family history, a low socioeconomic level and an increased number of children were factors that increased the frequency of enuresis nocturna in our region.

Pilonidal sinus disease: risk factors for postoperative complications and recurrence.

The aim of this study is to analyze the risk factors for complications and recurrence in pilonidal sinus disease. The prospective study consisted of 144 patients with pilonidal sinus disease who were operated on at Dicle University Medical Faculty, Department of General Surgery, between February 2008 and December 2010. Patients receiving the Limberg flap totaled 106 (73.6%), while 38 (26.4%) had primary closure. Postoperative complications developed in 42 subjects (29.2%), and recurrence occurred in 19 (13.2%). The Limberg flap method was statistically considered as a risk factor for postoperative complications (P  =  0.039). Regarding recurrence, family tendency (P  =  0.011), sinus number (P  =  0.005), cavity diameter (P  =  0.002), and primary closure (P  =  0.001) were found to be risk factors. Postoperative complication rate is higher in the Limberg flap method than primary closure method. The risk of recurrence is related to family tendency, sinus number, cavity diameter and anesthesia type and is also higher in primary closure.

Prevalence and risk factors of epilepsy among school children in eastern Turkey.

Epilepsy is a serious chronic brain disorder of childhood. We performed a cross-sectional prevalence study, determined the prevalence of childhood epilepsy, and identified the significance of certain risk factors for epilepsy among 1625 primary-school students aged 6-14 years, living in the center of Kars province. A questionnaire was prepared according to the definitions and principles of the Commission on Epidemiology and Prognosis, International League Against Epilepsy. Twenty-two children were diagnosed as epileptic. The point prevalence of active epilepsy in males was 4.9/1000, and in females 12.4/1000, representing a total of 8.6/1000. The cumulative prevalence in males was 11.0/1000, and 16.1/1000 in females, representing a total of 13.5/1000. Febrile convulsions, family history of epilepsy, serious maternal illness during pregnancy, a history of head trauma, antenatal/postnatal problems, and a history of neonatal jaundice were statistically significantly related to the development of epilepsy.

Course anomalies of extracranial internal carotid artery and their relationship with pharyngeal wall: an evaluation with multislice CT.

PURPOSE: The goal of our study was to measure the prevalence of anomalies in the extracranial segment of internal carotid artery (ICA), to measure the carotid-pharyngeal distance (CPD). METHODS: Computed tomography (CT) angiography images of 607 patients were retrospectively examined. The course anomaly and CPD were obtained at different image plane. The patients were divided into four groups according to their age. RESULTS: The incidence of course anomaly in ICA was shown to be 60.3 %. Prevalence of course anomaly showed an increase with age (p < 0.001). Women had more ICAs with a course anomaly than men (p < 0.001). Mean CPD among all ICAs was found to be 11.13 mm. When CPD values were compared between the groups, group 1 and group 2 did not have a significant difference, however, there was a significant difference between other groups (p < 0.05). The CPD significantly decreased with age (p < 0.001). In ICAs that showed a straight course, the mean CPD was 13.0 mm, while in ICAs that showed course anomaly, the mean CPD was determined to be 9.49, showing a significant difference (p < 0.05). CONCLUSION: In conclusion, the number of ICAs that show a course anomaly increases with age, while the CPD decreases. The CPD is decreased in groups that show anomalies. The detection of a decreased CPD before surgery may lower the chance of a perioperative hemorrhage due to artery damage during pharyngeal procedures. Hence, while reporting neck CT angiographies, it may be valuable to also report the presence of ICA anomalies and CPD.

Percutaneous Endoscopic Gastrostomy: Mortality and Risk Factors for Survival.

BACKGROUND: The present study evaluated long-term risk factors for survival in patients who have undergone Percutaneous endoscopic Gastrostomy, as well as morbidity and mortality rates. METHODS: The retrospective study included 44 patients who underwent placement of a percutaneous endoscopic gastrostomy tube at various departments at Dicle University Medical Faculty between April 2008-September 2010. RESULTS: The study evaluated 23 women (52.3%) and 21 men (47.7%), with a median age of 50 ± 20 (17 - 87) years. Median time for Percutaneous endoscopic Gastrostomy placement was 23 ± 8.3 (5 - 45) minutes per patient. Total morbidity was 15.9%, including wound infection (4), tube occlusion (1), peristomal leakage (1), and abdominal wall bleeding (1). Short-term complications were not associated with albumin level (P = 0.312).The median hospital stay was 49.34 ± 60.99 (1 - 314) days. The mean follow-up period was 13.07 ± 13.12 (1 - 41) months. The above-normal level of albumin was found to be effective on survival (P = 0.024). Mortality occurred in 18 (40.9%) patients during the follow-up. CONCLUSIONS: Percutaneous endoscopic Gastrostomy is both safe and effective in that it does not require surgical operation and it can be performed under surface anesthesia. The serum albumin level with patients who have undergone percutaneous endoscopic gastrostomyis an effective factor for survival.

Relationships between respiratory function disorders and serum copper levels in copper mineworkers.

The aim of this study was to investigate the respiratory function disorders that could be related to dust exposure during the production of copper mine in copper mineworkers (CMWs). The study included 75 male CMWs (mean age, 32.0 ± 7.1 years, 58.6% smokers) and 75 male age- and smoking status-matched healthy control subjects. Serum Cu level was significantly higher in the CMW group (0.80 ± 0.62 µg/ml) than the control group (0.60 ± 0.39 µg/ml) (p = 0.017). Significant negative correlations were found between serum Cu level and forced expiratory volume in first second (r = -0.600; p < 0.001) and between serum Cu level and forced vital capacity (r = -0.593; p = <0.001) in CMWs. Serum Cu level was significantly higher in the restrictive type pulmonary function disorders group (1.36 ± 0.62 µg/ml) than obstructive type (0.90 ± 0.55 µg/ml) and normal pulmonary function pattern group (0.53 ± 0.43 µg/ml) (p < 0.001). Patients with radiological parenchymal abnormalities had significantly higher serum copper levels than those without abnormalities (1.53 ± 0.52 vs. 0.71 ± 0.52 µg/ml, respectively; p = 0.002). In conclusion, result of the study has shown a negative association between pulmonary functions disorders and radiological abnormalities and serum Cu levels in CMWs.

Deep neck space infections: a retrospective review of 173 cases.

PURPOSE: The purpose of this study is to review our recent experience with deep neck infections and emphasize the importance of radiologic evaluation and appropriate treatment selection in those patients. MATERIALS AND METHODS: The records of 173 patients treated for deep neck infection at the Department of Otolaryngology and Head and Neck Surgery of Dicle University Hospital during the period from 2003 to 2010 were retrospectively reviewed. Their demography, symptoms, etiology, seasonal distribution, bacteriology, radiology, site of deep neck infection, durations of the hospital admission and hospital stay, treatment, complications, and outcomes were evaluated. The findings were compared to those in the available literature. RESULTS: Dental infection was the most common cause of deep neck infection (48.6%). Peritonsillar infections (19.7%) and tuberculosis (6.9%) were the other most common cause. Pain, odynophagia, dysphagia, and fever were the most common presenting symptoms. Radiologic evaluation was performed on almost all of the patients (98.3%) to identify the location, extent, and character (cellulitis or abscesses) of the infections. Computed tomography was performed in 85.3% of patients. The most common involved site was the submandibular space (26.1%). In 29.5% of cases, the infection involved more than one space. All the patients were taken to intravenous antibiotic therapy. Surgical intervention was required in 95 patients (59.5%), whereas 78 patients (40.5%) were treated with intravenous antibiotic therapy alone. Life-threatening complications were developed in 13.8% of cases; 170 patients (98.3%) were discharged in stable condition. CONCLUSION: Despite the wide use of antibiotics, deep neck space infections are commonly seen. Today, complications of deep neck infections are often life threatening. Although surgical drainage remains the main method of treating deep neck abscesses, conservative medical treatment are effective in selective cases.

An intervention study for viral hepatitis. Peer-led health education among high school students.

OBJECTIVE: To check the effectiveness of peer-led education in improving the knowledge, attitudes, and behavior of high school students regarding viral hepatitis (VH). METHODS: This study was conducted at 29 high schools in Erzurum city center, Turkey between February and May 2007. The study design is a prospective before-and-after intervention trial. In this study, 2930 students from 29 different schools were included. A total of 559 volunteer students were trained as peer educators. These students applied a standard education to their peers. RESULTS: The total knowledge scores of peer educators before was 7.99 ± 2.73, and 13.91 ± 3.85 after peer-training (p=0.000). The total knowledge scores of other students increased from 7.27 ± 2.85 to 11.20 ± 4.21 (p=0.000). There was an increase in all correct answers to the knowledge questions after the intervention (p=0.000). Response to the questions exploring attitude of students towards people infected with hepatitis virus significantly changed after the training (p=0.002). There was also a significant positive change in the behaviors after the intervention (p=0.000). CONCLUSION: The significant increase in the knowledge of students trained by their peers proves this method is effective to be utilized in the prevention strategies regarding VH infections. Further studies with long term follow-up would be useful to demonstrate the long term value of peer education.
