Qualitative evaluation of reasons for healthcare professionals being unvaccinated against COVID-19.

Background and Aim: The importance of immunization has increased even more during the pandemic. This study aimed to evaluate the reasons for healthcare professionals not being vaccinated against COVID-19 and to develop solutions for the causes. Subject and Methods: This qualitative study was carried out with in-depth interviews between July 2021 and October 2021, with 32 healthcare professionals and five key people who had never been vaccinated against COVID-19. Results: The most common reasons that healthcare professionals were not vaccinated against COVID-19 were concerns about vaccine side effects, believing that the vaccine is not effective, distrust of the vaccine content and COVID-19 treatment methods, the rapid production of the vaccine, the fact that the vaccine is produced with a new technology, thinking that the vaccine is not the definitive solution, seeing themselves as healthy and young, and the belief that they would have a mild case of the disease and recover. The main themes were COVID-19 vaccine-related reasons, individual reasons/group effects, contextual reasons, and vaccination-related general issues. The main sub-themes were vaccine production, distrust, risk perception, policies and infodemic. Conclusion: It has been seen that the uncertainty, infodemic, and insecurity that emerged especially during the pandemic period are related to each other. As knowledge and awareness about the disease increase, there is an increase in risk perception. For this reason, social information studies should be increased and physicians should be enabled to use media tools more effectively.

Impact of Health Workers' Choice of COVID-19 Vaccine Booster on Immunization Levels in Istanbul, Turkey.

BACKGROUND: There are limited data regarding short- and medium-term IgG antibody levels after the CoronaVac and BNT162b2 vaccines. This study aimed to investigate the antibody responses of health workers who initially received two doses of CoronaVac one month apart followed by a booster dose of either CoronaVac or BNT162b2, as well as determine whether either vaccine provided superior results. METHODS: This research represents the second phase of a mixed-methods vaccine cohort study and was conducted between July 2021 and February 2022. The participants (n = 117) were interviewed in person and blood samples were collected before and at 1 and 6 months after the booster vaccination. RESULTS: BNT162b2 was found to have greater immunogenic potential than CoronaVac (p < 0.001). Health workers without chronic disease exhibited statistically significant increases in antibody levels after both vaccines (p < 0.001), whereas only BNT162b2 caused a significant increase in antibody levels in participants with chronic disease (p < 0.001). Samples obtained before and at 1 and 6 months after the booster vaccination revealed no age- or sex-based differences in IgG-inducing potential for either vaccine (p > 0.05). Antibody levels were comparable in both vaccine groups before the booster regardless of COVID-19 history (p > 0.05); however, antibody levels were significantly higher after the BNT162b2 booster at 1 month (<0.001) and at 6 months, except among participants who had a positive history of COVID-19 infection (p < 0.001). CONCLUSIONS: Our results suggest that even a single booster dose of BNT162b2 after initial vaccination with CoronaVac provides a protective advantage against COVID-19, especially for risk groups such as health workers and those with chronic diseases.

Assessment of Anxiety, Depression and Work-Related Strain Levels of Healthcare Professionals Working in Operating Rooms and Intensive Care Units During the COVID-19 Outbreak.

OBJECTIVE: The purpose of the study was to determine the levels of work-related strain, anxiety, and depression in health professionals working in operating rooms and intensive care units who deal with the diagnosis, treatment, and care of coronavirus disease 19 patients. METHODS: The population of the study consisted of 320 healthcare professionals working in the operating room and intensive care units. After providing detailed information about the study to the participants, a questionnaire consisting of 21 questions including sociodemographic infor- mation and working life characteristics, 14 questions from the Hospital Anxiety and Depression Scale, and 18 questions from the Work-Related Strain Inventory (WRSI) were administered under supervision. RESULTS: In total, 58.8% of the participants were working in intensive care units, and 41.2% of the participants were in the operating room. The scores obtained from Work-Related Strain Inventory were found to be statistically significantly high in those who wanted to choose a differ- ent profession, those who were on duty during the coronavirus disease 19 pandemic process, those whose spouses followed coronavirus disease 19 patients during the pandemic, those who encountered a suspicious situation and had a coronavirus disease 19 test, those who had difficulty in accessing personal protective equipment, and those who thought that their lives were in danger during the pandemic process. Participants with anxiety risk according to Hospital Anxiety and Depression Scale-Anxiety subscale and depression risk according to Hospital Anxiety and Depression Scale-Depression subscale were found to be 153 (47.8%) and 300 (93.8%), respectively. CONCLUSIONS: It was found that Work-Related Strain Inventory and anxiety-depression rates were significantly high in both the operating room and intensive care unit workers who actively provided healthcare services to patients diagnosed with coronavirus disease 19.

Violence towards workers in hospital emergency services and in emergency medical care units in Samsun: an epidemiological study.

BACKGROUND: The aim of this study was to determine the frequency of exposure to some form of violence during the previous 12 months and the State-Trait Anxiety levels of emergency medical care (EMC) and emergency service (ES) workers in Samsun. METHODS: A cross-sectional study was conducted in all EMC (5) units and ES (4) in Samsun, between April 1 and April 30, 2004. A self-administered questionnaire was sent to all of the workers (n=320). RESULTS: Of the workers, 280 (87.5%) completed the survey. A total of 202 (72.1%) participants reported that they had witnessed some form of violence. ES workers (75.9%) were more often exposed to violence than EMC workers (62.3%) (c2=5.08, p<0.05). The multivariate analysis demonstrated that age, gender and anxiety regarding repetition of exposure to violence were related with higher state anxiety point, while anxiety regarding repetition of exposure to violence was related with higher trait anxiety point. CONCLUSION: This evidence clearly indicates that violence in ES and EMC units is a common concern. The necessary framework for the reduction and elimination of violence in the workplace should be provided.

The Prevalence of Suicidal Ideation in Adolescents and Associated Risk Factors: An Example from Turkey.

INTRODUCTION: Identifying risk factors is important in intervening in suicide, which is a preventable cause of death in adolescents. The aim of the present study was to evaluate the prevalence of suicidal ideation and risk factors for suicidal thought in high school students aged 15-18 years. METHODS: The data were obtained from questionnaire forms administered to 2438 high school students aged 15-18 years. Risk factors that might be associated with suicidal thought were identified using logistic regression analysis. RESULTS: The prevalence of suicidal ideation in adolescents in the last 12 months was 17.9%. Being female [OR 1.95, (CI 95% 1.47-2.59)], use of alcohol [OR 2.44, (CI 95% 1.63-3.68)] and addictive drugs [OR 1.78, (CI 95% 1.07-2.97)], being in physical fights [OR 1.76, (CI 95% 1.34-2.32)], having no close friends [OR 2.17, (CI 95% 1.34-3.52)], bullying(victimization) [OR 1.99, (CI 95% 1.43-2.77)], and other psychosocial distress were significant risk factors in the development of suicidal ideation. CONCLUSIONS: Solutions for decreasing risky behaviors for health, particularly the use of alcohol and addictive drugs, prevention of violence between peers, and strengthening of social relationships, must be developed.

Diagnosing carpal tunnel syndrome with Doppler ultrasonography: a comparison of ultrasonographic measurements and electrophysiological severity.

INTRODUCTION: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. Diagnosis is based on clinical history, physical examination, and electrophysiological studies. Imaging techniques are performed for difficult-to-diagnose cases because they provide information about the morphology of the median nerve. More recently, it has been shown that Doppler ultrasonography can detect increased intraneural blood flow in CTS. The aim of our study is to evaluate the relationship between the severity of CTS, hypervascularization, and cross-sectional area (CSA) to determine the diagnostic value of Doppler ultrasonography. PATIENTS AND METHODS: The study group comprised 125 wrists of 75 patients who had been diagnosed with CTS, both clinically and electrophysiologically. The control group comprised 100 wrists of 50 healthy volunteers. Wrists were classified into five stages of CTS severity based on electrophysiologic studies. A radiologist examined the wrists blindly with grayscale images and Doppler ultrasonography to assess CSA and hypervascularization. RESULTS: A total of 121 wrists were included. There were 28 wrists with minimal CTS severity stage, 36 with mild, 36 with moderate, and 21 with severe. The sensitivity and specificity of CSA and hypervascularization in detecting CTS was 90.9, 94.0, 93.4, and 90.0%, respectively. There was a significant correlation between CTS severity and hypervascularization (p < 0.005) for all stages. CONCLUSION: Our study shows that Doppler ultrasonography results strongly correlate with CTS severity. Hence, this is a useful method for diagnosing CTS and estimating its severity.

Emergency service use by older people in Samsun, Turkey.

During the first 50 years of the 21st century, the world population aged 65 and older is expected to triple. Proper care of the older patient is one of the major priorities of many health care systems. In this descriptive study, patients treated and transported by 112 Emergency Help and Rescue Service in Samsun Province during the year 2004 were surveyed through review of command center records. All patients who were 65 years of age and older were included in the study. Collected data included patient sex and age, number of patients accessing emergency medical service (EMS) per hours of the day and per season, clinical diagnosis, and patient outcomes. In all, 2210 patients aged 65 years and older were identified; this group accounted for 24.5% of all records reviewed (n=9015). The rate of EMS use was highest in those older than 65 years of age (26 of 1000/y). Similar associations of ambulance transportation with older age and off-hour presentation were noted, as was increased usage during colder months of the year. Cardiovascular, neurologic, and respiratory problems were the 3 most frequent reasons for use of EMS. In almost three fourths of cases, outcome was recorded as transport to the hospital. Data presented here highlight the need for continued monitoring of EMS usage patterns so that planners will be prepared to accommodate the needs of the increasingly aging population.

Survey of general practitioners' knowledge about Helicobacter pylori infection.

BACKGROUND: Helicobacter pylori, occurring throughout the world and causing gastroduodenal diseases, is one of the most common chronic bacterial agents in humans. The purpose of this study was to measure the general practitioners' (GPs) knowledge and practices pertaining to H. pylori infection. METHODS: A cross-sectional type questionnaire survey was conducted in all of 19 primary health care centres (PHCC) in Samsun, Turkey, between November 1 and December 31, 2003. The questionnaire was sent to 124 GPs and 109 (87.9 %) of those filled in. They were requested to answer the questions on the knowledge, sources of medical information, diagnostic tests and treatment to H. pylori. RESULTS: Medical journals were the most frequently used source of information on H. pylori, being cited by 86 (78.9%) of GPs. Ninety-two (84.4%) of the GPs reported having used one or more tests and 17 (15.6%) never used any test for the diagnosis of H. pylori infection. Only 9.8% had used stool antigen test for diagnosis. GPs reported that they would prescribe symptomatic treatment without ordering diagnostic tests for 29 (26.6%). 54.1% of the GPs explain that they sent patients with H. pylori infection to a specialist, and most used a triple drug regimen containing a PPI. Treatment duration varies between 7 to 28 days. 80.7 of the GPs treat patients for 14 days. CONCLUSION: GPs may not have enough knowledge about the importance of stool antigen test or possibility of usage of this test. GPs have not sufficient knowledge about the difference between symptomatic and asymptomatic individuals. It is thought that GPs preferred to treat the patients with suspected ulcer empirically or to send them to a specialist because of the limited diagnostic conditions. The efforts to educate the GPs about the algorithms regarding the management of H. pylori infection during post-graduation period should be improved in PHCCs.

Obstetric outcomes of adolescent pregnancies in Turkey.

Pregnancy in adolescence has been and continues to be a problem in public health. The purpose of this study was to investigate obstetric outcomes of adolescent pregnancies in Samsun, Turkey. A cross-sectional study was conducted between January 1 and December 31, 2004, at 3 hospitals in Samsun, Turkey. Of the 10,100 women who gave birth during this period, 357 (3.5%) were 18 years of age or younger; these patients were included in the study. Participants with a history of any chronic disease were excluded. Data were provided as median values (min- max) and percentages. In this study, the rate of birth for females 18 years or younger was found to be 35 per 1000. The median age of participants was 18 (14-18) years. The prevalence of cesarean section was calculated at 55.7%. Prevalences of low-birthweight infants, preterm delivery, and eclampsia/preeclampsia were recorded as 44 (12.3%), 34 (9.5%), and 30 (8.4%) cases, respectively. Although the stillbirth rate was determined to be 1.7%, no congenital deformity was noted in infants, and none of the mothers died. The cephalopelvic disproportion rate was 5.9%, and only 2 adolescents experienced abruptio placentae. To reduce the occurrence of adolescent childbearing, pregnancy intentions must be assessed in multiple ways. Information/education may provide benefit to those female adolescents with inconsistent pregnancy intentions.

What Is the Audiological Evaluation Time for those Aged 0-5 Years and Older?

OBJECTIVE: The purpose of this study was to determine the time taken to perform audiological evaluation under routine clinical test conditions. We also aimed to investigate relevant variables and reasons for increases in test time. MATERIALS AND METHODS: The total test times of 300 patients were recorded and calculated using an "Audiological Evaluation Time Calculation Form." Behavioral and objective test times were determined and calculated separately. The patients were divided into groups on the basis of age, educational status, cooperation, and coordination in order to determine the effects of these factors on the test time. RESULTS: The mean time for behavioral tests was 41.85 min for children below the age of 6 years and 36.2 min for those above that age. The times for transient evoked otoacoustic emission, distortion product otoacoustic emission, automated auditory brainstem response, and auditory brainstem response tests were 6.4/4.3 min, 4.8/6.9 min, 14.4 min, and 48.0/47.5 min, respectively, for the two age groups. The shortest total test times were obtained from the 15-29 age group, high school/university levels, and patients who cooperated. Conversely, the longest total test times were found in 6-14 age group, those with no literacy, and who hardly cooperated. CONCLUSION: Although audiological evaluation methods have well-defined international standards, numerous factors, including patient conditions, clinician experience, and equipment, may have an adverse effect on test times. Determining the optimum patient number in one working day can help reduce workload and work stress and prevent possible errors of diagnosis/treatment. It will also help determine staff numbers needed in audiology clinics.

Antibiotic prescribing and urinary tract infection.

The aim of this study was to evaluate the diagnostic and therapeutic approach to urinary tract infections (UTIs) by primary care physicians, in Samsun, Turkey. Data were obtained from the records of 2083 visits at eight primary care areas. Trained research students were stationed on site at each of the eight primary care centres between 1 June, 1999 and 1 July, 1999. Patients who had acute cystitis, recurrent UTIs, acute pyelonephritis and acute urethritis were included in the study. A total of 2083 office visits were recorded and 419 (20.1%) of the patients had UTIs and acute urethritis. Antibiotics were prescribed for 94.7% of the patients with UTIs and urethritis. Some 74% of prescriptions were consistent with current recommendation, but only 41% of the antibiotic prescriptions were rational according to dosage, dosage interval and duration of therapy. Urinary antiseptic agents were prescribed to 75% of patients with UTIs. These data indicate that polypharmacy is widespread in our region; primary care physicians need to review their knowledge about the diagnosis and treatment of UTIs and acute urethritis.

Primary care physicians' approach to diagnosis and treatment of hepatitis B and hepatitis C patients.

BACKGROUND: Infections caused by hepatitis B virus (HBV) and hepatitis C virus (HCV) are considered to be important health problems worldwide. The purpose of this study was to measure the general practitioners (GPs)' basic knowledge on HBV and HCV risk factors in determining their practice about this subject. METHODS: A cross-sectional type questionnaire survey was carried out at all of 32 primary healthcare centers (PHCCs) in Samsun, Turkey, between March 1 and April 31, 2002. The questionnaires were sent to 160 GPs and 129 (80.6%) of them answered the questionnaires. Knowledge, role responsibility, self-efficacy and attitudes and beliefs regarding to viral hepatitis B and hepatitis C were asked. RESULTS: Most of the GPs had adequate knowledge about transmission of HBV and HCV and also about risk factors for transmission of viruses. Most of the GPs (83.7%) were aware of recommendations for approach to a baby, born from HBsAg positive mother. They have limited facilities in diagnosis of viral hepatitis. Of the participants, 108 (83.7%) expressed that they could not diagnose HBV infections and 126 (97.7%) of them stated that they could not make the diagnoses of HCV infection in their local healthcare centers. The knowledge about treatment of chronic viral hepatitis B (21.8%) and C patients (17.8%) with elevated ALT is not sufficient. CONCLUSION: GPs' knowledge about risks of viral hepatitis was adequate in this study. They were not able to diagnose and follow up of these infections at PHCCs because of limited knowledge about chronic viral hepatitis and diagnostic facilities. GPs should be informed about current advice in diagnosis and treatment of chronic of HBV and HCV infections.

A geographic information system-based analysis of ambulance station coverage area in Samsun, Turkey.

INTRODUCTION: The location of ambulance stations are of great importance, as location is a determining factor of whether ambulances are able to respond to emergency calls within the critical period. The aim of the present study was to determine whether the ambulance stations in the provincial centre of Samsun, Turkey, were able to cover their entire operational area within 10 mins of receiving an emergency call. METHODS: This study was based on emergency calls received by the emergency medical services of the study area. Detailed address data from the calls was used to produce thematic maps using the geographic information system (GIS). Buffer analysis was used to determine the adequacy of the stations' locations in relation to the time taken to respond to the emergency calls. RESULTS: In the study area, there were a total of 11,506 emergency ambulance calls made in 2009, which revealed a call density of 0.7 calls per ha and 23.8 calls per 1,000 population. A total of 75.8% of the calls were made due to medical reasons, while 11.6% were related to traffic accidents. The GIS-based investigation revealed that the 10-min coverage areas for the four ambulance stations in the provincial centre of Samsun served 76.9% of the area and 97.9% of its population. Of the 10,380 calls for which detailed address data were available, 99.2% were within the stations' 10-min coverage areas. CONCLUSION: According to the buffer analysis, the ambulance stations in the provincial centre of Samsun are able to reach 97.9% of the population within the critical 10-min response time. This study demonstrates that GIS is an indispensable tool for processing and analysing spatial data, which can in turn aid decision-making in the field of geographical epidemiology and public health.

Prevalence of juvenile fibromyalgia syndrome in an urban population of Turkish adolescents: impact on depressive symptoms, quality of life and school performance.

BACKGROUND: Juvenile Fibromyalgia Syndrome (JFMS) is a chronic health condition characterized by widespread musculoskeletal pain and multiple tender points (TP). The objective of this study was to determine the prevalence of JFMS in the urban population of Samsun and to determine the impact of JFMS on depression symptoms, school performance and quality of life (QOL). METHODS: A cross-sectional study was conducted in 1109 children (mean age (14.8 ± 2.0) years old). A questionnaire was applied to the children and a medical examination including TP was performed. Yunus and Masi's criteria were used for diagnosis of JFMS. The children with JFMS were compared with an age and sex matched non-JFMS group. Depression was assessed with Children's Depression Inventory (CDI) and QOL was evaluated with Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). RESULTS: Sixty-one (5.5%) (13 boys and 48 girls) of 1109 children met the diagnostic criteria of JFMS. While PedsQL scores of children with JFMS were lower than the non-JFMS group for physical, emotional, social, school functioning and total score (P = 0.001), CDI total score was higher in the JFMS group than in the non-JFMS group (P = 0.001). The JFMS group reported more school absences (P = 0.001) and the average school grade was lower in the JFMS group than in the non-JFMS group (P = 0.03). CONCLUSION: The prevalence of JFMS is high in school age children. Since JFMS is a common problem of childhood, early diagnosis and identification of the disorder and more comprehensive and successful treatment approaches with appropriate psychological assistance may prevent more complex and severe problems in adulthood.

A survey of cross-infection control procedures: knowledge and attitudes of Turkish dentists.

OBJECTIVES: The objective of this study was to investigate the knowledge, attitudes and behavior of Turkish dentists in Samsun City regarding cross-infection control. MATERIAL AND METHODS: A questionnaire was designed to obtain information about procedures used for the prevention of cross-infection in dental practices and determine the attitudes and perceptions of respondent dental practitioners to their procedures. The study population included all dentists in the city of Samsun, Turkey, in April 2005 (n=184). The questionnaire collected data on sociodemographic characteristics, knowledge and practice of infection control procedures, sterilization, wearing of gloves, mask, use of rubber dam, method of storing instruments and disposal methods of contaminated material, etc. Questionnaire data was entered into a computer and analyzed by SPSS statistical software. RESULTS: From the 184 dentists to whom the questionnaires were submitted, 135 participated in the study (overall response rate of 73.36%). As much as 74.10% dentists expressed concern about the risk of cross-infection from patients to themselves and their dental assistants. Forty-three percent of the participants were able to define 'cross-infection' correctly. The greatest majority of the respondents (95.60%) stated that all patients have to be considered as infectious and universal precautions must apply to all of them. The overall responses to the questionnaire showed that the dentists had moderate knowledge of infection control procedures. CONCLUSIONS: Improved compliance with recommended infection control procedures is required for all dentists evaluated in the present survey. Continuing education programs and short-time courses about cross-infection and infection control procedures are suitable to improve the knowledge of dentists.

Establishment of interdisciplinary child protection teams in Turkey 2002-2006: identifying the strongest link can make a difference!

OBJECTIVES: The University of Iowa Child Protection Program collaborated with Turkish professionals to develop a training program on child abuse and neglect during 2002-2006 with the goals of increasing professional awareness and number of multidisciplinary teams (MDT), regional collaborations, and assessed cases. This paper summarizes the 5-year outcome. METHODS: A team of instructors evaluated needs and held training activities in Turkey annually, and provided consultation when needed. Descriptive analysis was done via Excel and SPSS software. RESULTS: Eighteen training activities were held with 3,570 attendees. Over the study period, the number of MDTs increased from 4 to 14. The MDTs got involved in organizing training activities in their institutions and communities. The number of medical curriculum lectures taught by MDTs to medical students/residents, conferences organized by the MDTs, and lectures to non-medical professional audiences increased significantly (R(2)=91.4%, 83.8%, and 69.2%, respectively). The number of abuse cases assessed by the MDTs increased by five times compared to pre-training period. CONCLUSIONS: A culturally competent training program had a positive impact on professional attitudes and behaviors toward recognition and management of child abuse and neglect in Turkey. The need to partner with policy makers to revise current law in favor of a greater human services orientation became clear. PRACTICE IMPLICATIONS: Pioneers in developing countries may benefit from collaborating with culturally competent instructors from countries with more developed child protection systems to develop training programs so that professional development can improve recognition and management of child abuse and neglect.

Left ventricular aneurysm in the scope of gated perfusion SPECT: accuracy of detection and ejection fraction calculation.

PURPOSE: The objective of this trial was to investigate the capacity of gated perfusion SPECT (GPS) to detect left ventricular aneurysm (ANV) by comparing QGS and 4D-MSPECT (4DM) algorithms with radionuclide ventriculography (RVG). Secondarily, the comparison of GPS ejection fraction (EF) measurements with those of contrast left ventriculography (LVG) and RVG was aimed. METHODS: Twenty-five patients with ANV confirmed by LVG were studied. The patients underwent RVG and rest Tc-99m-tetrofosmin GPS 1 week after LVG. A 9-segment model was used both in RVG and GPS evaluation. Aneurysm was defined by scoring the wall motion (WM) and phase analysis in RVG; perfusion, wall thickening and WM in GPS. RESULTS: The detection rate of ANV was 96%, 84% and 52% for RVG, QGS and 4DM, respectively. The LVG mean EF (43.52% +/- 16.93%) was significantly higher (P < 0.01) than those of RVG (29.40% +/- 10.90), QGS (30.04% +/- 13.25%) and 4DM (34.92% +/- 13.01%). Moderate to high EF correlation values were obtained between LVG and GPS (r = 0.71-0.79) and GPS-RVG (r = 0.69). There was no significant EF difference between the radionuclide methods except between 4DM-EF and RVG-EF (5.52%, P < 0.05). Wide Bland-Altman limits were observed between the radionuclide methods in EF comparisons (range: 30.5-38.5%). CONCLUSION: GPS seems to have a role in the non-invasive investigation of ANV. QGS-GPS proved to be more reliable (84%) than 4DM-GPS (52%) in the ANV detection. The localization and the extent of the aneurysm itself as well as perfusion and function of adjacent segments may affect aneurysm diagnosis by means of GPS. RVG, QGS-GPS and 4DM-GPS seem not to be interchangeable for routine EF calculation in ANV patients.

A comparative evaluation of health related quality of life and depression in patients with fibromyalgia syndrome and rheumatoid arthritis.

The aim of this study was to compare health related quality of life (HRQoL) and assess functional and psychological status in rheumatoid arthritis (RA), fibromyalgia syndrome (FS) patients and controls (each 30 subjects). Demographic characteristics, pain and sleep disturbance by Visual Analog Scale, depression by Beck Depression Inventory (BDI), disease impact by fibromyalgia impact questionnaire, DAS-28, and HRQoL by SF-36 were gathered. The FS group scored significantly worser than the RA group with respect to physical role, social functioning and bodily pain subscales of SF-36. The scores of all SF-36 subscales were significantly lower in FS and RA patients than controls except mental health score. All of the subscales of SF-36 were negatively correlated with BDI scores in FS patients. In RA group, the DAS-28 scores were inversely correlated with all of SF-36 subscales. In conclusion, presence of comorbid depression must be taken into account when determining HRQoL in FS and RA. Essentials improving the HRQoL are management of depression in FS and control of disease activity in RA.

Effects of pars plana vitrectomy on retrobulbar haemodynamics in diabetic retinopathy.

BACKGROUND: The purpose of the present study was to determine the effects of pars plana vitrectomy on retrobulbar haemodynamics in patients with proliferative diabetic retinopathy (PDR). METHODS: Colour Doppler imaging was used for measurement of blood flow velocities and resistive index of the ophthalmic artery (OA), posterior ciliary arteries (PCA) and central retinal artery (CRA) in 14 eyes of 14 patients with PDR before pars plana vitrectomy and at the 1 and 6 months after operation. The patients were also treated by laser photocoagulation before or during surgery. Twenty age- and sex-matched healthy subjects were used as control group. RESULTS: Mean peak systolic velocity and the end diastolic velocity of the CRA in the patients with PDR were lower and the mean resistive index was higher than in those of the control group (P < 0.05). The mean end diastolic velocity of OA in the patients was lower and the mean resistive index was higher than in the control group (P < 0.05). The peak systolic velocity of the OA and the end diastolic velocity of the CRA were significantly increased (P = 0.043 and P = 0.018, respectively) and the mean resistive index of the CRA was significantly decreased after pars plana vitrectomy (P = 0.043). No significant changes were detected among preoperative and postoperative values of peak systolic velocity, end diastolic velocity, and resistive index of the PCA and the mean velocity of the central retinal vein (P > 0.05). CONCLUSIONS: The blood flow velocities of OA and CRA are decreased but the resistive index is increased significantly in patients with PDR. Pars plana vitrectomy in patients with PDR may decrease resistive index and improve blood flow in the CRA.
