RESUMO

BACKGROUND: The World Health Organization has set ambitious targets for the global elimination of tuberculosis. However, these targets will not be achieved at the current rate of progress. METHODS: We performed a cluster-randomized, controlled trial in Ca Mau Province, Vietnam, to evaluate the effectiveness of active community-wide screening, as compared with standard passive case detection alone, for reducing the prevalence of tuberculosis. Persons 15 years of age or older who resided in 60 intervention clusters (subcommunes) were screened for pulmonary tuberculosis, regardless of symptoms, annually for 3 years, beginning in 2014, by means of rapid nucleic acid amplification testing of spontaneously expectorated sputum samples. Active screening was not performed in the 60 control clusters in the first 3 years. The primary outcome, measured in the fourth year, was the prevalence of microbiologically confirmed pulmonary tuberculosis among persons 15 years of age or older. The secondary outcome was the prevalence of tuberculosis infection, as assessed by an interferon gamma release assay in the fourth year, among children born in 2012. RESULTS: In the fourth-year prevalence survey, we tested 42,150 participants in the intervention group and 41,680 participants in the control group. A total of 53 participants in the intervention group (126 per 100,000 population) and 94 participants in the control group (226 per 100,000) had pulmonary tuberculosis, as confirmed by a positive nucleic acid amplification test for Mycobacterium tuberculosis (prevalence ratio, 0.56; 95% confidence interval [CI], 0.40 to 0.78; P<0.001). The prevalence of tuberculosis infection in children born in 2012 was 3.3% in the intervention group and 2.6% in the control group (prevalence ratio, 1.29; 95% CI, 0.70 to 2.36; P = 0.42). CONCLUSIONS: Three years of community-wide screening in persons 15 years of age or older who resided in Ca Mau Province, Vietnam, resulted in a lower prevalence of pulmonary tuberculosis in the fourth year than standard passive case detection alone.

RESUMO

Introduction: Breast cancer is one of the most common cancers and cause of death among women globally. Mortality due to breast cancer was higher in lower (LMICs) and middle-income countries than high income countries (HICs) mostly due to lack of timely detection and treatment. There was limited evidence related to breast cancer screening practice among women in Eastern Ethiopia. Therefore, the aim of this study was to assess breast cancer screening practice and its associated factors among women in this area. Methods: A community based descriptive cross-sectional study design was conducted among 422 randomly selected women in Kersa district, Eastern Ethiopia using systematic sampling. Data were collected using pretested interviewer administered questionnaire. Logistic regression was used to analyse the association between the dependent and independent variables. Results: The overall breast cancer screening practice among women was 6.9%. Women with the age of 26 years and above were 2.3 times more likely to have breast cancer screening practice as compared to women with age of 20-25 years (AOR=2.3; 95% CI: 1.4, 3.7), and women who had good knowledge on breast cancer risk factors were 3.4 times more likely to had breast cancer screening as compared to their counterpart (AOR=3.4; 95% CI: 1.3, 9.4). The women who had ever heard about breast cancer screening were 2.8 times more likely to have breast cancer screening as compared to those who had never heard about breast cancer screening (AOR=2.8; 95% CI: 1.2, 6.5). Conclusion: The overall breast cancer screening practice was very low among women in the study area. Age and women's knowledge towards breast cancer risk factors and breast cancer screening information were identified as important factors for breast cancer screening practice.

RESUMO

Introduction: While HIV care among tuberculosis (TB) patients is successfully implemented and monitored, it is not routinely reported among "presumptive TB patients without TB". The present study describes the ascertainment of HIV status and receipt of antiretroviral therapy (ART) and the associated factors among presumptive TB patients (with and without TB) in 35 public health facilities of Masvingo district of Zimbabwe from January to June 2017. Methods: This was an analysis of secondary programme data. We performed log binomial regression to calculate adjusted relative risks (aRR) and 95% confidence intervals (CI). Results: Of 1369 presumptive TB patients, 1181 (86%) were ascertained for HIV status (98% among those subsequently diagnosed with TB, 83% among non-TB). Of them, 748 (63%) were HIV positive, more among TB patients (69%) than those without TB (61%). Among HIV-positive patients, 475 (64%) received ART, significantly higher among TB patients (78%) compared to those without TB (57%). Patients without TB were significantly more likely to have non-ascertained for HIV status (aRR=2.4, 95% CI=1.4-5.0) and not receiving ART (aRR=1.8, 95% CI=1.6-2.0), compared to those with TB. Conclusion: We found high rates of HIV status ascertainment among presumptive TB patients. But, ART uptake was poor among "presumptive TB patients without TB", despite implementation of "test and treat" strategy in Zimbabwe. The programme should step up the monitoring of HIV status and ART receipt among presumptive TB patients, by introducing an indicator in the quarterly reports of the national TB programme.

RESUMO

The association between deafness and visual disorders is frequent. These disorders range from simple refractive disorder to severe disease that can lead to disability. Hence the interest of early screening. This study aims to highlight the importance of multidisciplinary management and of the need for ophthalmological examination in each deaf child. We conducted a prospective monocentric data collection from medical records of 200 children followed for hypoacousia from January 2014 to January 2015. Each child underwent complete ophthalmological examination, ENT examination and clinical examination. Data from 155 medical records were collected. Ocular involvement was found in 47 patients, reflecting a rate of 30.4%. Bilateral involvement was found in 45 patients. The main syndromic causes were: Usher syndrome (8 casess), Waardenbourg syndrome (5 cases), Alport syndrome (3 cases), Wolfram syndrome (2 cases), Goldenhar syndrome (3 cases), Cogan syndrome (3 cases), Franceschetti-Kleinsyndrome (1 case), Charge syndrome(1 case), otomandibular syndrome (1 case), Stickler syndrome(1 case), Alström syndrome (1 case), Refsum disease (1 case), Susac syndrome (1 case) and KID Syndrome (1 case). Screening for ocular involvement allowed to shorten the average length of cochlear implantation from 9 months to 3 months. There are numerous ocular and auditory involvements because of the embryological and cellular similarities of these two organs, including the retina and the inner ear. The diagnosis of these involvements is facilitated by the presence of facial dysmorphism; on the other hand, diagnosis is difficult when there are visual and auditory sensorineural involvements. Early diagnosis of ocular and auditory involvements allows for best psychomotor development and optimal social inclusion. Therefore multidisciplinary management is necessary to allow for the best psychomotor, orthophonic and visual rehabilitation.

RESUMO

BACKGROUND AND STUDY AIMS: Hepatitis C virus (HCV) infection often causes asymptomatic disease and patients are frequently diagnosed at an advanced stage. Oral direct acting antivirals (DAAs) are successful in treating HCV with high sustained virologic response (SVR) and excellent tolerability. The aim of this study is to evaluate cost-effectiveness of a broad screening strategy proposing screening to all undiagnosed members of a population (comprehensive HCV screening), in the general adult population, emergency department (ED) attendees, men who have sex with men (MSM) and people who inject drugs (PWID). PATIENTS AND METHODS: We populated a theoretical model with Belgian data. A decision tree model simulating HCV screening and diagnosis was combined with a Markov state transition model simulating treatment. There was one screening round per year during five years. In the ED population only one screening round was considered. RESULTS: The model calculated that more HCV patients could be detected and treated with comprehensive screening compared to the current situation. Incremental cost per incremental quality adjusted life years (QALY) gained was lower than 10.000€/QALY for one and for five screening rounds in the general population (5.139 and 5.200 respectively), in ED attendees (one screening round 5.967), in MSMs (4.292 and 4.302 respectively) and in PWIDs (3.504 and 3.524 respectively). CONCLUSION: A broad screening strategy combined with treatment is likely to be a cost-effective strategy to detect and treat HCV infected patients and diminish the HCV burden in Belgium.

RESUMO

We aimed to determine the accuracy and failure of OAK device, an automated screening, for the assessment of fall risk in a prospective cohort of healthy adults aged over 65 years. The algorithm for fall risk assessment of the centers for disease control and prevention (CDC) was used as reference standard. Of the 183 individuals recruited, the CDC algorithm classified 80 as being at moderate/high risk and 103 at low risk of falling. OAK device failure incidence was 4.9% (confidence interval [CI] upper limit 7.7%), below the preset threshold for futility-early termination of the study (i.e., not above 15%). The OAK device showed a sensitivity of 84% and a specificity of 67% (receiver operating characteristic [ROC] area 82%; 95% confidence interval [CI] 76-88%), not reaching the preplanned target sensitivity (not lower than 85%). Diagnostic accuracy was not far from the sensitivity levels similar to those obtained with other fall risk assessment. However, some limitations can be considered.ClinicalTrials.gov identifier: NCT02655796.

RESUMO

OBJECTIVE: To estimate benefits and harms of different colorectal cancer screening strategies, stratified by (baseline) 15-year colorectal cancer risk. DESIGN: Microsimulation modelling study using MIcrosimulation SCreening ANalysis-Colon (MISCAN-Colon). SETTING: A parallel guideline committee (BMJ Rapid Recommendations) defined the time frame and screening interventions, including selection of outcome measures. POPULATION: Norwegian men and women aged 50-79 years with varying 15-year colorectal cancer risk (1-7%). COMPARISONS: Four screening strategies were compared with no screening: biennial or annual faecal immunochemical test (FIT) or single sigmoidoscopy or colonoscopy at 100% adherence. MAIN OUTCOME MEASURES: Colorectal cancer mortality and incidence, burdens, and harms over 15 years of follow-up. The certainty of the evidence was assessed using the GRADE approach. RESULTS: Over 15 years of follow-up, screening individuals aged 50-79 at 3% risk of colorectal cancer with annual FIT or single colonoscopy reduced colorectal cancer mortality by 6 per 1000 individuals. Single sigmoidoscopy and biennial FIT reduced it by 5 per 1000 individuals. Colonoscopy, sigmoidoscopy, and annual FIT reduced colorectal cancer incidence by 10, 8, and 4 per 1000 individuals, respectively. The estimated incidence reduction for biennial FIT was 1 per 1000 individuals. Serious harms were estimated to be between 3 per 1000 (biennial FIT) and 5 per 1000 individuals (colonoscopy); harms increased with older age. The absolute benefits of screening increased with increasing colorectal cancer risk, while harms were less affected by baseline risk. Results were sensitive to the setting defined by the guideline panel. Because of uncertainty associated with modelling assumptions, we applied a GRADE rating of low certainty evidence to all estimates. CONCLUSIONS: Over a 15 year period, all screening strategies may reduce colorectal cancer mortality to a similar extent. Colonoscopy and sigmoidoscopy may also reduce colorectal cancer incidence, while FIT shows a smaller incidence reduction. Harms are rare and of similar magnitude for all screening strategies.

RESUMO

OBJECTIVE: To determine the utility of the screener and opioid assessment for patients with pain-revised (SOAPP-R) for patients with cancer-related pain. DESIGN: The authors performed a retrospective analysis of cancer patients screened with the SOAPP-R. Opiate abuse was determined using a combination of urine drug screens and analysis of patients' electronic medical records. SETTING/PATIENTS: Patients who were seen at a palliative care clinic presenting with pain or needing an opioid prescription at an academic medical center with any type of cancer were screened using the SOAPP-R (N = 69). OUTCOME MEASURES: Aberrant opioid-related behavior was determined using a combination of provider notes and urine drug screens. RESULTS: A positive SOAPP-R score (⩾18) was observed in 27 participants (39.1 percent). The sensitivity and specificity of the SOAPP-R in the study population was 0.75 and 0.80, respectively. CONCLUSIONS: The SOAPP-R, in its current form, may have value in screening patients with cancer for substance abuse. Incorporation of the screening tool in palliative and oncology settings may help reduce opioid abuse in cancer patients.

RESUMO

CLINICAL QUESTION: Recent 15-year updates of sigmoidoscopy screening trials provide new evidence on the effectiveness of colorectal cancer screening. Prompted by the new evidence, we asked: "Does colorectal cancer screening make an important difference to health outcomes in individuals initiating screening at age 50 to 79? And which screening option is best?" CURRENT PRACTICE: Numerous guidelines recommend screening, but vary on recommended test, age and screening frequency. This guideline looks at the evidence and makes recommendations on screening for four screening options: faecal immunochemical test (FIT) every year, FIT every two years, a single sigmoidoscopy, or a single colonoscopy. RECOMMENDATIONS: These recommendations apply to adults aged 50-79 years with no prior screening, no symptoms of colorectal cancer, and a life expectancy of at least 15 years. For individuals with an estimated 15-year colorectal cancer risk below 3%, we suggest no screening (weak recommendation). For individuals with an estimated 15-year risk above 3%, we suggest screening with one of the four screening options: FIT every year, FIT every two years, a single sigmoidoscopy, or a single colonoscopy (weak recommendation). With our guidance we publish the linked research, a graphic of the absolute harms and benefits, a clear description of how we reached our value judgments, and linked decision aids. HOW THIS GUIDELINE WAS CREATED: A guideline panel including patients, clinicians, content experts and methodologists produced these recommendations using GRADE and in adherence with standards for trustworthy guidelines. A linked systematic review of colorectal cancer screening trials and microsimulation modelling were performed to inform the panel of 15-year screening benefits and harms. The panel also reviewed each screening option's practical issues and burdens. Based on their own experience, the panel estimated the magnitude of benefit typical members of the population would value to opt for screening and used the benefit thresholds to inform their recommendations. THE EVIDENCE: Overall there was substantial uncertainty (low certainty evidence) regarding the 15-year benefits, burdens and harms of screening. Best estimates suggested that all four screening options resulted in similar colorectal cancer mortality reductions. FIT every two years may have little or no effect on cancer incidence over 15 years, while FIT every year, sigmoidoscopy, and colonoscopy may reduce cancer incidence, although for FIT the incidence reduction is small compared with sigmoidoscopy and colonoscopy. Screening related serious gastrointestinal and cardiovascular adverse events are rare. The magnitude of the benefits is dependent on the individual risk, while harms and burdens are less strongly associated with cancer risk. UNDERSTANDING THE RECOMMENDATION: Based on benefits, harms, and burdens of screening, the panel inferred that most informed individuals with a 15-year risk of colorectal cancer of 3% or higher are likely to choose screening, and most individuals with a risk of below 3% are likely to decline screening. Given varying values and preferences, optimal care will require shared decision making.

RESUMO

A 2014 report evaluating accuracy of serologic testing for transfusion-transmissible viruses at African blood center laboratories found sensitivities of 92%, 87%, and 90% for detecting infections with human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV), respectively (1). Following substantial investments in national blood transfusion service (NBTS) laboratories, in 2017 investigators tested proficiency at 84 blood center laboratories (29 NBTS and 55 non-NBTS) in seven African countries. A blinded panel of 25 plasma samples was shipped to each participating laboratory for testing with their usual protocols based on rapid diagnostic tests (RDTs) (2) and third and fourth generation enzyme immunoassays (EIA-3 and EIA-4). Sensitivity and specificity were estimated using separate regression models that clustered assays by laboratory and adjusted for assay type and NBTS laboratory status. Mean specificities were ≥95% for all three viruses; however, mean sensitivities were 97% for HIV-positive, 76% for HBV-positive, and 80% for HCV-positive samples. Testing sensitivities for all viruses were high when EIA-3 assays were used (≥97%). Lower sensitivities for HBV-positive samples and HCV-positive samples were associated with assay types other than EIA-3, used primarily by non-NBTS laboratories. Proficiency for HIV testing has improved following international investments, but proficiency remains suboptimal for HBV and HCV testing. In sub-Saharan African blood centers, the quality of rapid tests used for HBV and HCV screening needs to be improved or their use discouraged in favor of EIA-3 tests.

RESUMO

Human papillomavirus (HPV) infection is a crucial health problem and caused substantial malignancy diseases among female worldwide. We aim to investigate the distribution of HPV subtype and the status of cervical cancer and precancerous lesions caused by HPV infection in North China Plain population. A total of 61,870 samples of outpatients and inpatients from January 2015 to May 2017 at the Affiliated Hospital of Jining Medical University were collected. All of the samples were tested by rapid flow-through hybridization HPV genotyping. Approximately 17,280 of the cases tested positive for HPV, indicating an infection rate of 27.9%. Approximately 7009 cases were compared to the results of cytological diagnosis. The top five HPV genotypes were HPV-16 (4.5%), HPV-52 (2.9%), HPV-58 (2.8%), HPV-53 (1.9%), and HPV-81 (1.9%). The youngest age group (age < 20 years) showed the highest infection rate (59.9%), and then decreased with age. As the degree of cervical lesions worsened gradually, the rate of high-risk HPV infection increased, such as 24.3% (322/1324) in the Cervicitis, 31.30% (560/1785) in the CINI, 54.1% (568/1050) in the CINII, 80.1% (693/865) in the CIN III, and 99.5% (428/430) in the cervical cancer group. These findings were significantly different from the 9.7% (155/1555) observed in the normal medical examination group (P < .05). This is the first study to demonstrate the characteristics of HPV and the association with cervical lesions in North China Plain population.

RESUMO

Children bear a substantial burden of suffering when it comes to tuberculosis. Ironically, they are often left out of the scientific and public health advances that have led to important improvements in tuberculosis diagnosis, treatment, and prevention over the past decade. This Series paper describes some of the challenges and controversies in paediatric tuberculosis, including the epidemiology and treatment of tuberculosis in children. Two areas in which substantial challenges and controversies exist (ie, diagnosis and prevention) are explored in more detail. This Series paper also offers possible solutions for including children in all efforts to end tuberculosis, with a focus on ensuring that the proper financial and human resources are in place to best serve children exposed to, infected with, and sick from all forms of tuberculosis.

RESUMO

Introduction: high risk HPV is the perpetrator of cervical cancer disease, however screening and vaccination is not included in cervical cancer prevention program within public hospitals in Kenya. This descriptive study assessed the association of specific microbial STI and socio-demographic characteristics and practices with cervical cytomorphologic presentations in regards to pre cervical cancer grades amongst health seeking patients attending the reproductive health clinic of Nakuru County referral hospital, a public hospital under newly devolved health services governance. Methods: a total of 142 patients (AGC/AIS, n=8; HSIL, n=59; LSIL, n=35; controls, n=40) whose median age ranged between 20-70 years were purposively sampled. A structured questionnaire with closed and open ended entries was administered and STI screening including Pap smear examination for cytomorphological profiling done according to revised 2014 Bethesda classification. Associations were established using chi-square and multivariate logistic regression model to determine prediction of cervical atypia manifestations. Results: a majority of the study participants had only primary education or no education in AGC/AIS (63%) and HSIL (73%) relative to LSIL (49%) and controls (53%) (P=0.017). Koilocyte rates were higher in AGC/AIS (25%), HSIL (52%) and LSIL (77%) compared controls (12.5%) (P<0.0001). ASCUS predominated in HSIL (61%) and LSIL (86%), while almost all AGC/AIS had AGCUS (88%). HR HPV 16/18 infection rates were higher in AGC/AIS (100%), HSIL (80%) and LSIL (83%) relative to controls (10%) (P<0.0001), and was associated with higher risk of having AGC/AIS (OR, 2.0; 95% CI, 1.940-1.947; P<0.0001); HSIL, (OR, 36.3; 95% CI, 9.5-139.5; P<0.0001); and LSIL (OR, 50.1; 95% CI, 12.0-209.0; P<0.0001). Conclusion: altogether, pre-cervical cancer in Kenyan women is characterized by koilocytosis and ASCUS probably from the high rates of HPV 16/18 infections. Promoting cancer education and screening for high risk HPV infections and pre-cancerous lesions will improve women's reproductive health.

RESUMO

Introduction: Persistent high-risk HPV (hrHPV) infection is higher among women living with HIV/AIDS thus increasing their risk for cervical cancer. We evaluated the virological and immunological correlates of cervical dysplasia in HIV-infected women. Methods: A cohort of 220 consenting women attending the antiretroviral clinic of the Federal Medical Centre, Keffi, Nigeria was tested for cervical human papilloma virus (HPV) infection using PCR. The prevalent HPV genotypes were determined by DNA sequencing. CD4+T count and type specific HPV was correlated with cervical cytology. Descriptive and inferential statistical analysis of the data was done using the statistical package for social sciences (SPSS) version 20 (SPSS Inc, Illinois, USA) for analysis after validation. Results: Overall HPV prevalence was 54.1% while the hrHPV prevalence was 35.9%. Premalignant and malignant lesions were observed among participants with CD4+T counts between 200-300/mm3. A statistically significant association was observed between cervical premalignant lesions and CD4+ count (X2=24.747, P value=0.001) as well as hrHPV infections (X2=46.800, P<0.001). Conclusion: Risk stratification with HPV screening among HIV-infected women will help in early case management of cervical precancerous lesions.

RESUMO

Introduction: Cancer is a public health problem that affect women more than men. The aim of the study was to describe the epidemiological and histopathological features of gynecological malignancies in the city of Yaoundé, Cameroon. Methods: This was a descriptive cross-sectional study of histologically proven gynecological cancers over a 10-year period (2008-2017) in the Gynecology and Pathological Anatomy Departments of the University Teaching Hospital of Yaoundé. Results: A total of 682 cancers were identified among which, 342 gynecological cancers, for an overall frequency of 50.1% and an annual frequency of 34.2 cases on average. There was a trend suggesting an increase annual frequency over time. The cervix was the most frequent location with 182 cases (53.2%); followed by breast with 96 cases (28.1%); endometrium with 33 cases (9.7%) and ovaries 15 cases (4.4%). These patients were on average 51.9±13.7 years old, mostly housewives (56.8%), married (60.4%), multiparous (61.3%) and referred (62.6%). Histopathologically, cervical cancer was predominantly squamous cell carcinoma (86.8%), invasive (80.9%) and well differentiated (45.5%). For breast cancers, the majority were ductal carcinomas (78.1%), invasive (92%), and histological grade SBR II (50.6%). The most common histopathological types of endometrial and ovarian cancer were adenocarcinoma (72.2%) and serous cystadenocarcinoma (46.7%), respectively. Conclusion: Gynecological cancers are common. Screening is expected to increase at 30 years for cervical cancer and start at age 40 with mammography for breast cancer.

RESUMO

INTRODUCTION: An analysis of the impact of health promotion efforts as part of the Polish Universal Neonatal Hearing Screening Program demonstrated diagnostic efficacy. The health promotion efforts had been efficiently implemented via a proper execution of this long-term Program by the Great Orchestra for Christmas Charity (WOSP) foundation. OBJECTIVE: The aim of the study was to demonstrate the impact of health promotion efforts by public benefit organizations by analyzing the WOSP foundation's involvement in the Program in Poland during 2003-2015. MATERIAL AND METHODS: Statistical data for 2003-2015 were obtained from the database of the Department of Otolaryngology and Laryngeal Oncology at Poznan University of Medical Sciences. The analyzed data included the rates of hearing-impairment detection (phase 1), diagnosis (phase 2), and treatment (phase 3) in the newborns included in the Program, as well as the documentation of expenditures based on WOSP's foundation annual financial reports. RESULTS: A total of 4,672,704 newborns were screened from 2003-2015, which amounted to approximately 360,000 screened patients per year. During the analyzed 12 years of the Program, the mean proportion of children who underwent screening was 96.1%, with an observable, gradual increase in the number of children undergoing diagnostic assessments (phase 2) for a suspected hearing impairment, with the largest amount of money having been allocated to the Program implementation and expended in its early stages. The total cost of financing the Program by the year 2015 was 51,841,712 PLN. CONCLUSIONS: The Polish Universal Neonatal Hearing Screening Program resulted in an improvement in the quality in the screening test, ensured more thorough diagnostics, and shortened the time needed to implement the appropriate treatment.

RESUMO

BACKGROUND AND AIM: Colorectal cancer (CRC) screening can effectively reduce cancer-associated mortality. In Germany, individuals over the age of 50 or 55 have access to CRC screening services. However, utilization rates are persistently low, particular in the male population. This observational study investigates the effect of standard versus gender-specific invitation letters on utilization of CRC screening services. METHODS: We analyzed utilization rates of individuals who were insured by a large health insurance fund in Bavaria, Germany. Persons who became eligible for CRC screening received a standard (2013-2014) or a gender-specific invitation letter (2015-2016). We compared utilization rates within 6 months after receipt of the invitation letter using billing codes of the health insurance fund. RESULTS: Invitation letters were sent to 49 535 individuals, of which 48.8 % were gender-specific. The overall utilization rate did not differ between recipients of the standard versus gender-specific invitation letter (11.6 % vs 11.1 %; RR: 0.97 [0.92-1.02], p = 0.19). However, uptake of screening colonoscopy was significantly higher among recipients of gender-specific invitations (2.9 % vs 3.5 %; RR: 1.21 [1.04-1.39], p = 0.01), whereas utilization of fecal occult blood tests declined (10.4 % vs 9.7 %; RR: 0.93 [0.88-0.99], p = 0.016). CONCLUSIONS: Gender-specific design of invitation letters can modify the patients' preference for specific CRC screening services and increase the acceptance of screening colonoscopy.

RESUMO

BACKGROUND: In Germany, colorectal cancer (CRC) screening includes a fecal blood test or colonoscopy, but not a sigmoidoscopy, which has been shown to reduce CRC incidences and mortality. Our aim was to compile physicians' experiences with sigmoidoscopy and their assessments of this procedure being an additional, possible screening method for early CRC detection. METHODS: At the end of 2015, gastroenterologists and internists in Lower Saxony and North Rhine-Westphalia who regularly perform screening colonoscopies in outpatient care were contacted per mail. Standardized telephone interviews consisting of 17 questions and lasting 10-15 minutes were conducted. RESULTS: Nearly two-thirds (56/87) of the respondents reject sigmoidoscopy as an acceptable early detection method. Compared to colonoscopy, key features of the sigmoidoscopy include more favorable patient-related aspects, while procedural aspects, except sedation, clearly rate in favor of the colonoscopy. In the instance that colonoscopy is rejected, 75 % of the physicians consider a sigmoidoscopy to be a possible alternative. CONCLUSIONS: The survey provides important practical insights into outpatient sigmoidoscopy. A majority of the physicians does not support evidence-based sigmoidoscopy for CRC screening. However, individuals who reject a colonoscopy are, in line with the current guideline, identified as a target group for a screening sigmoidoscopy. The benefit from an additionally offered sigmoidoscopy in CRC screening should be further analyzed with special consideration given to the preferences of insurees within the German healthcare system.

RESUMO

BACKGROUND: Ophthalmic pathologies may further complicate the sensory input of patients with congenital hearing loss; however, data on children with coexisting impairment of vision and hearing is outdated, from before universal implementation of hearing screening programs. OBJECTIVES: To examine the different ophthalmic pathologies among children with congenital sensorineural hearing loss (SNHL) before or after the introduction of a universal newborn hearing screening program (UNHSP). METHODS: Retrospective cohort study was conducted of 91 children diagnosed with congenital SNHL between 2005 and 2016 in a tertiary pediatric hospital. All patients completed an ophthalmologic examination, including assessment of visual acuity, refraction, ocular motility, slit lamp examination, and indirect funduscopy. Radiological assessment and genetic analysis were offered to all caregivers. RESULTS: Average age at diagnosis was 4.1 years. Nineteen children (21%) were diagnosed with an ophthalmic condition, of which the most common were refractive pathologies. Diagnosis of an ophthalmic pathology was twice as likely in the pre-UNHSP era (14 children, 27%) compared to the post-UNHSP era (5 children, 13%). Out of 91 children, 57 (63%) underwent a computed tomography scan and/or magnetic resonance imaging. Imaging was positive for structural abnormalities in 23 children (40%). There was no correlation between imaging and ophthalmic conditions. Genetic analysis was performed in 67 patients (74%). CONCLUSIONS: The ophthalmic assessment of babies and children with congenital SNHL may yield in significant numbers of children with concomitant ophthalmic pathologies. Implementation of a UNHSP allows early diagnosis and treatment of coexisting ophthalmic and hearing conditions.
