RESUMEN
OBJECTIVE: Studies addressing small and diminutive polyps and their potential of harboring advanced histologic features (AH) are scarce in Hispanics. We aimed to determine the prevalence of AH in a cohort of Hispanics. METHODS: A retrospective review of medical records of patients who had a colonoscopy from 2005 through 2010. The data collected included demographics, indications, history (personal/family) of colon cancer and/or polyps, and polyp histology. Polyps with high-grade dysplasia, prominent villous component, adenocarcinoma or serrated were classified as having AH. RESULTS: The population comprised 1884 patients, and 3835 polyps were evaluated; 63.3% were diminutive (1-5 mm), 22.7% small (6-9 mm), and 13.9% large (≥10 mm). The prevalence of AH for small and diminutive polyps were 4.9% and 1.1%, respectively. Of the polyps with AH, 11.9% were diminutive and 19.6% small. Small polyps were 5.04 times more likely to harbor AH than were diminutive polyps. Distal rather than proximal polyps were more likely to harbor AH. Furthermore, AH was >7 times more common in small (6-9 mm) polyps identified during diagnostic or surveillance colonoscopies compared to screening colonoscopies. CONCLUSION: The prevalence of AH was significantly associated with size, location (distal), and procedure indication. Although diminutive polyps (<6 mm) were less likely to harbor AH, the risk for non-Hispanics was higher than previously reported. The "resect and discard" strategy for polyps ≤ 1 cm should be used with caution in ethnically diverse cohorts, as the risk for AH may be higher in Hispanics than in non-Hispanic Whites.

Progressive retinal atrophy (PRA) is a term used in veterinary medicine to describe inherited and progressive retinal diseases characterized by progressive retinal degeneration and loss of vision. In the Golden Retriever (GR) breed, the mutations associated with PRA have an autosomal recessive inheritance pattern. This study aimed to verify the allele frequencies of PRA1, PRA2, and PRA-prcd in the GR breed in Brazil. A total of 121 GR DNA samples (n = 66 females and n = 55 males) were analyzed. All animals assessed in this study were identified as wild-type (121/121 animals; 100%) for PRA1 and PRA2 mutations; therefore, no carrier or homozygous animals were identified in this population. For the PRA-prcd mutation, 118 animals (118/121 animals; 97.52%) were wild-type. Three animals were genotyped as heterozygous for PRA-prcd (3/121 animals; 2.47%), demonstrating that this mutation is still present in some bloodlines and animals in Brazil, even with a rare prevalence. Five animals (5/121 animals, 4.2%) had a previous eye disease, which was diagnosed by a veterinarian as entropion (2 animals), keratoconjunctivitis sicca (1 animal), corneal ulcer (1 animal), and bilateral blindness (1 animal). This dog with bilateral blindness was identified as wild type homozygous for three mutations assessed in this study; therefore, blindness was not associated with the investigated mutations. In addition, the vast majority (98.3%) of Brazilian breeders assessed in this study were unaware of these mutations as a cause of blindness in the Golden Retriever. Therefore, the present study will serve to disseminate knowledge about PRA and its genetic etiologies, as well as to support future studies with other Brazilian GR populations.
RESUMEN
Introduction Chlamydia trachomatis (CT) has been related to fallopian tube damage and infertility. Its prevalence in the population that attend public services is known; however, there is scant data on this factor in private infertility clinics. The objective of this study is to verify the prevalence of CT among women attending a private in vitro fertilization (IVF) reference clinic in southern Brazil. Methods This is a cross-sectional study carried out between January 1, 2019, and August 30, 2021, at an IVF private clinic in southern Brazil. Infertile women between 18 and 50 years old, who provided a morning urinary sample for reverse transcription-polymerase chain reaction (RT-PCR) test for CT analysis, were included in the study. The variables studied included the patient's age, body mass index (BMI), duration of infertility, type of infertility, indication for IVF, and detection or not of CT in the urine. Results The prevalence of CT was 10.84% (22 out of 203; 95% CI: 7.27-15.87). Patients with secondary infertility were older and had more ovarian and tubal factors compared to cases of primary infertility. The tubal factor was the most prevalent (27.3% in women with primary infertility and 35.8% in those with secondary). Time of infertility and BMI were similar between groups. Our results are derived from a single private IVF clinic which reduces the external validity. Conclusion The prevalence of 10.84% of CT in this population raises the importance of screening for sexually transmitted infections for proper treatment and to achieve better IVF outcomes.
RESUMEN
Objectives. Lower back pain (LBP) is a common health problem worldwide, affecting an increasing number of individuals. Military firefighters (MFFs) face high levels of physical and psychological demands and are commonly exposed to different occupational risk factors. This study aimed to estimate the prevalence of chronic lower back pain (CLBP) in Brazilian enlisted MFFs. Methods. This cross-sectional study was carried out at the Military Firefighters Department of the Brazilian Federal District (Corpo de Bombeiros Militar do Distrito Federal [CBMDF]). The estimated sample size was 608 MFFs. Results. Of the 623 participants, 575 valid and complete questionnaires were analyzed. A total of 183 participants reported CLBP, indicating a point prevalence of 31.8% (95% confidence interval [CI] [28.2, 35.4]). The prevalence of acute and subacute LBP was 9.2% (95% CI [7.1, 11.9]), and 59% (95% CI [54.9, 62.9]) reported no back pain. CLBP was more common among men aged 40-49 years, who were insufficiently active and overweight. Conclusion. Around one-third of the study population reported CLPB. Prevalence estimates of CLPB were greater among men and those between 40 and 49 years old. Our data support the need for programs to prevent and treat CLBP among firefighters.

INTRODUCTION: There is conflicting data on how thoracic kyphosis changes throughout adulthood. We evaluated mid and lower thoracic kyphosis (MTK) in various age groups and the influence of age, sex and coronal curve (CC) on MTK. MATERIAL AND METHODS: We studied 1323 patients 15-80 years-old (54.4% females) previously evaluated with chest radiographs. We established three groups: patients 15-40 (group 1); 41-60 (group 2) and 61-80 years old (group 3). MTK (T5-T12) and CC were measured using Cobb's method. We established differences in MTK between groups using ANOVA with Bonferroni correction. We performed a correlation analysis of MTK with age and CC, and a linear regression analysis to determine if age, sex and CC independently predicted MTK. RESULTS: MTK increased with older age: mean MTK group 1 = 23.4°; group 2 = 27.9° and group 3 = 34.4°, p < 0.01. The increase in MTK was observed in both genders. Scoliosis was more common in females (15.4%) than in males (6.7%), p < 0.01. MTK was correlated with age (r = 0.4; p < 0.01) and slightly correlated with CC (r = 0.07, p < 0.01). MTK was larger in females than in males (29.1° vs. 27.6°, p < 0.01). Age (ß-coefficient = 0.26) and CC (ß-coefficient = 0.14), but not sex, independently influenced MTK in the regression analysis. CONCLUSION: MTK increases with advancing age during adulthood in both genders; CC, but not sex, was an independent predictor of MTK.

Background: Despite current policies of salt iodination, iodine deficiency is still a global public health problem, especially in women. So far, conflicting evidence has been suggested for the prevalence of iodine deficiency in Brazil. Objective: To estimate the prevalence of iodine deficiency and associated factors in women of childbearing age in Brazil. Methods: A systematic review was conducted using databases (PubMed, LILACS, WHO, Scopus, and Capes' dissertation and thesis), from inception to May 2020. Meta-analyses of proportions were performed using the variance inverse for the fixed model. Reporting and methodological quality were assessed using the Joanna Briggs Institute tool to prevalence studies. Results: Our review identified seven studies published between 2002 e 2017, including 1354 participants, especially pregnant women. All studies presented at least one quality limitation, mainly regarding the sampling method (i.e., convenience) and small sample size. The prevalence of iodine deficiency ranged among studies from 16% to 62%. In contrast, the meta-analysis identified a mean prevalence of 40% (95% confidence interval, CI 37%-43%) for pregnant women and 13% (95% CI 4%-24%) for non-pregnant women. Cumulative meta-analysis suggests a tendency of higher iodine deficiency prevalence from 2018 in pregnant women. Conclusions: Although this systematic review identified studies with poor methodological and reporting quality, a high prevalence of iodine deficiency was identified in pregnant women, reinforcing the importance of national nutritional policies for monitoring iodine status in this population. Future studies should consider random probabilistic sampling, appropriate sample size, and pre-defined subgroup analysis to adequately inform the prevalence of iodine deficiency and associated factors in women of childbearing age and support health policies
Antecedentes: A pesar de las políticas actuales de yodación de la sal, la deficiencia de yodo sigue siendo un problema de salud pública mundial, especialmente en las mujeres. Hasta ahora, se han sugerido pruebas contradictorias sobre la prevalencia de la deficiencia de yodo en Brasil. Objetivo: Estimar la prevalencia de deficiencia de yodo y factores asociados en mujeres en edad fértil, en Brasil. Métodos: Se realizó una revisión sistemática, buscando en PubMed, LILACS, OMS, Scopus y la base de datos de disertaciones y tesis de Capes desde el inicio hasta mayo de 2020. Se realizaron metanálisis de proporciones utilizando la variancia inversa para el modelo fijo. La calidad de información y metodológica se evaluó utilizando la herramienta del Institute Joanna Briggs para estudios de prevalencia. Resultados: Nuestra revisión identificó siete estudios publicados entre 2002 y 2017, incluyendo 1354 participantes, especialmente mujeres embarazadas. Todos los estudios presentaron al menos una limitación de calidad, principalmente con respecto al método de muestreo (es decir, la conveniencia) y el pequeño tamaño de la muestra. La prevalencia de la deficiencia de yodo varió entre los estudios del 16% y el 62%, mientras que el metanálisis identificó una prevalencia media del 40% (intervalo de confianza del 95%, IC 37%-43%) para las mujeres embarazadas y del 13% (IC del 95% 4%-24%) para mujeres no embarazadas. El metanálisis acumulativo sugiere una tendencia a una mayor prevalencia de deficiencia de yodo a partir de 2018 en mujeres embarazadas. Conclusiones: Si bien esta revisión sistemática identificó estudios con mala calidad metodológica y de reporte, se identificó una alta prevalencia de deficiencia de yodo en mujeres embarazadas, lo que refuerza la importancia de las políticas nutricionales nacionales para monitorear el estado de yodo en esta población. Los estudios futuros deben considerar el muestreo probabilístico aleatorio, el tamaño de muestra apropiado y el análisis de subgrupos predefinidos para informar adecuadamente la prevalencia de la deficiencia de yodo y los factores asociados en mujeres en edad fértil y para respaldar las políticas de salud

Objective: To estimate the prevalence of low-prognosis patients according to the POSEIDON criteria using real-world data. Design: Multicenter population-based cohort study. Settings: Fertility clinics in Brazil, Turkey, and Vietnam. Patients: Infertile women undergoing assisted reproductive technology using standard ovarian stimulation with exogenous gonadotropins. Interventions: None. Main outcome measures: Per-period prevalence rates of POSEIDON patients (overall, stratified by POSEIDON groups and by study center) and the effect of covariates on the probability that a patient be classified as "POSEIDON". Results: A total of 13,146 patients were included. POSEIDON patients represented 43.0% (95% confidence interval [CI] 42.0-43.7) of the studied population, and the prevalence rates varied across study centers (range: 38.6-55.7%). The overall prevalence rates by POSEIDON groups were 44.2% (group 1; 95% CI 42.6-45.9), 36.1% (group 2; 95% CI 34.6-37.7), 5.2% (group 3; 95% CI 4.5-6.0), and 14.4% (group 4; 95% CI: 13.3-15.6). In general, POSEIDON patients were older, had a higher body mass index (BMI), lower ovarian reserve markers, and a higher frequency of female factor as the primary treatment indication than non-POSEIDON patients. The former required larger doses of gonadotropin for ovarian stimulation, despite achieving a 2.5 times lower number of retrieved oocytes than non-POSEIDON patients. Logistic regression analyses revealed that female age, BMI, ovarian reserve, and a female infertility factor were relevant predictors of the POSEIDON condition. Conclusions: The estimated prevalence of POSEIDON patients in the general population undergoing ART is significant. These patients differ in clinical characteristics compared with non-POSEIDON patients. The POSEIDON condition is associated with female age, ovarian reserve, BMI, and female infertility. Efforts in terms of diagnosis, counseling, and treatment are needed to reduce the prevalence of low-prognosis patients.

Glanzmann's thrombasthenia (GT) is an autosomal recessive inherited disorder characterized by changes in platelet aggregation, leading to hemorrhage and epistaxis. To date, two independent mutations have been described in horses and associated with this disorder, a point mutation (c.122G > C) and a 10-base-pair deletion (g.1456_1466del) in the Integrin subunit alpha2ß gene (ITGA2B) of horses of different breeds (Quarter Horse, Thoroughbred, Oldenburg, and Peruvian Paso). ITGA2B codifies the αIIb subunit of the αIIbß3 integrin, also termed platelet fibrinogen receptor. Horses with GT have been diagnosed in the USA, Canada, Japan, and Australia. However, there are no studies on the prevalence of GT in horses. The aim of this study is to evaluate the prevalence of the mutations responsible for GT in horses in Brazil. A total of 1053 DNA samples of clinically healthy Quarter Horse (n = 679) and Warmblood horses (n = 374) were used. DNA fragments were amplified by PCR and sequenced. The genotype of each animal was analyzed and compared to the nucleotide sequence of the ITGA2B gene found on GenBankTM. There were no carriers in the analyzed samples, that is, all animals tested were wild type. Therefore, under the conditions in which this study was carried out, it can be inferred that GT seems to be extremely rare in the population of Quarter Horses and Warmbloods in Brazil, although it is not possible to affirm that there are no horses carrying mutated alleles in Brazil.
RESUMEN
Introducción: La diabetes mellitus tipo 1 (DM1) es la enfermedad crónica más frecuente en la edad pediátrica. La educación del niño con DM1 es fundamental para un adecuado control de la enfermedad. Las lipohipertrofias son una de las complicaciones más frecuentes que se producen por el tratamiento con insulina. Estas son consideradas problemas de colaboración y, por lo tanto, es labor de la enfermera controlar su aparición e intervenir para minimizar sus consecuencias. Objetivo: Determinar las características de las lipohipertrofias en niños diagnosticados con diabetes mellitus tipo 1. Métodos: Estudio descriptivo transversal mediante muestreo por conveniencia. Se evaluó la presencia, localización y tamaño de las lipohipertrofias y la relación de la persona que administra la insulina con el régimen de tratamiento. Se estudiaron pacientes de edades comprendidas entre 2 y 18 años que tuviesen, al menos, 3 meses de tratamiento insulínico. Se calculó el tamaño de la muestra mediante estimación de la proporción. Resultados: La prevalencia de lipohipertrofias fue del 44,5 por ciento. Sin embargo, entre los niños estudiados que se encontraban en tratamiento con múltiples dosis de insulina, el porcentaje se elevó a 53,8 por ciento. Los análogos de acción rápida eran inyectados principalmente en abdomen y brazo, los de acción lenta en glúteo y muslo. Los lugares con más lipohipertrofias eran muslos (superando el 50 por ciento), seguido de brazos y abdomen. Conclusiones: Se detectaron diferencias significativas en la aparición de lipohipertrofias entre los niños que portan bomba de insulina y los que utilizan un régimen de múltiples dosis de insulina. Por lo tanto, se podría recomendar la utilización de bomba de insulina o de catéteres de infusión subcutánea (i-Port ®) para la disminución de estas(AU)
Introduction: Type 1 diabetes mellitus (T1DM) is the most common chronic disease in the pediatric age. In order to obtain a positive control of this illness, the T1DM child education is basic. Lipohypertrophies are one of the most frequent difficulties that appear as a consequence of the insulin treatment. When this happen, is nurse's responsibility to monitor the appearance of lipohypertrophies and to try to reduce their consequences. Objectives: Establish the prevalence of lipohypertrophy in children with T1DM performed at the Pediatric Endocrinology Unit of the Hospital Universitario La Paz. Methods: To analyze lipohypertrophy it has been performed a descriptive study. The method used for the sampling was for convenience. Appearance, location and size of lipohypertrophies were evaluated. This has been related with person who administers the insulin and the treatment regimen. Results: Lipohypertrophy prevalence in the sample represented a 44.5 percent, however, between patients which were in a treatment with multiple daily injections this was 53.8 percent. Quick action analogues were mainly injected in abdomen and arms, slow action analogues were aministered in buttocks and leg. Legs were the part of the body with the most lipohypertrophies concentration (exceeded 50 percent), follow by arms and abdomen. Conclusions: Meaningful differences are shown in the appearance of lipohypertrophies between children in treatment with continuous subcutaneous insulin infusion and those that use a multiple daily injections treatment. Therefore, we concluded considering the possibility to recommend the use of continuous subcutaneous insulin infusion or indwelling catheters (i-Port ®) in order to decrease lipohypertrophies(AU)

Abstract Objectives: this study intends to estimate the rates, associated factors and trends of selfreported abortion rates in the northeast of Brazil. Methods: series of population-based surveys realized in Ceará, northeast of Brazil, one of the poorest states in the country. A sample of about 27,000 women of reproductive age was used. Abortion was assessed according to women´s information and rates were calculated using official population estimates. The trends and the association among socioeconomic and reproductive factors were studied using regressive models. Results: a trend for reduction in rates was identified. For induced abortion, the determinants were: not having a partner, condom in the last sexual intercourse, first child up to 25years old (AOR= 5.21; ACI: 2.9 - 9.34) and having less than 13years old at first sexual intercourse (AOR= 5.88; ACI: 3.29 - 10.51). For spontaneous abortion were: having studied less than 8 years, knowledge and use of morning-after pill (AOR= 26.44; ACI: 17.9 - 39.05) and not having any children (AOR= 3.43). Conclusions: rates may have been low due to self-reporting. Young age and knowledge about contraceptive methods were associated to both kinds of abortion, while education level along with spontaneous and marital status with induced. Programs to reduce abortion rates should focus on single younger women with low education.
Resumo Objetivos: este estudo objetiva estimar as taxas, fatores associados e tendência das taxas de aborto no Nordeste do Brasil. Métodos: série de estudos transversais realizada no Ceará, um dos estados mais pobres do país. Uma amostra de cerca de 27000 mulheres em idade reprodutiva foi utilizada. A ocorrência de aborto foi aferida através de informação dada pela participante e taxas foram calculadas usando estimativas populacionais oficiais. As tendências e associações entre fatores socioeconômicos e reprodutivos foram estudadas através de modelos regressivos. Resultados: foi identificada tendência de redução nas taxas de abortamento. Para aborto induzido, os determinantes foram não ter um parceiro fixo, ter utilizado camisinha na última relação sexual, ter tido o primeiro filho com menos de 25 anos (AOR= 5,21; ACI: 2,9 - 9,34), e ter tido a primeira relação com menos de 13 anos (AOR= 5,88; ACI: 3,29 - 10,51). Para o espontâneo, ter estudado menos de oito anos, conhecimento sobre a pílula do dia seguinte (AOR= 26,44; ACI: 17,9 - 39,05), e não ter filhos (AOR= 3,43). Conclusões: as taxas podem ser subestimadas por serem auto relatadas. Estar na adolescência e ter conhecimento sobre métodos contraceptivos foram associados aos dois tipos de aborto, enquanto nível educacional com o espontâneo e estado conjugal com induzido. Programas para reduzir taxas de abortamento deveriam focar em mulheres solteiras e com baixa educação.

AIMS: To assess the prevalence of fecal incontinence (FI) and associated factors in older adults. METHODS: The prevalence and factors associated with FI in older adults were studied by means the SABE study (Health, Well-being, and Aging). A group of 1,345 subjects were interviewed during the third wave of the SABE study performed in Sao Paulo, in 2010. The study included 64.3% females; the mean age of the participants was 70.4 years. The dependent variable was the positive answer for the question "In the last 12 months, have you ever lost control of bowel movements or stools?". Descriptive analysis and hierarchical logistic regression were performed. The independent variables were as follows: (a) demographics: gender, age and (b) clinical characteristics: self-reported chronic diseases, presence of cognitive and/or functional decline, depression and urinary incontinence symptoms, and nutritional status. RESULTS: The overall prevalence of FI was 11,7%, being 8.3% and 13.2% for males and females respectively. Among male subjects, the presence of malnutrition was associated with FI and thus presented a high relative risk index for its occurrence. Among female subjects, age group 70-74 years and some self-reported diseases or conditions such as mild depression, heart disease, urinary incontinence, and polypharmacy were associated with FI. For the first time in literature, polypharmacy appeared as an associated factor for FI for female older adults. CONCLUSIONS: The prevalence of FI in older adults was 11.7% and was mainly associated with advanced age and presence of heart disease, symptoms of depression, polypharmacy and urinary incontinence and malnutrition.

PURPOSE: The prevalence of spondylolysis reported from radiograph-based studies has been questioned in recent computed tomography (CT)-based studies in adults; however, no new data are available in pediatric patients. Spina bifida occulta (SBO), which has been associated to spondylolysis, may be increasing its prevalence, according to recent studies in adults in the last decades, but without new data in pediatric patients. We aimed to determine the prevalence of spondylolysis and SBO in pediatric patients using abdomen and pelvis CT as a screening tool. METHODS: We studied 228 patients 4-15 years old (107 males), who were evaluated with abdomen and pelvis CT scans for reasons not related to the spine. The entire lumbo-sacral spine was evaluated to detect the presence of spondylolysis and SBO. We compared the prevalence of spondylolysis in patients with and without SBO. A logistic regression analysis was performed to determine the effect of age and sex as independent predictors of spondylolysis and SBO. RESULTS: The prevalence of spondylolysis was 3.5 % (1.1-5.9 %); 2/8 patients presented with olisthesis, both with grade I slip. The prevalence of SBO was 41.2 % (34.8-59.2 %) (94 patients). Spondylolysis was not more frequent in patients with SBO than in patients without SBO. Male sex and decreasing age independently predicted the presence of SBO, but not of spondylolysis. CONCLUSION: We observed a 3.5 % prevalence of spondylolysis and a 41.2 % prevalence of SBO. SBO was significantly more frequent in males and younger patients.

PURPOSE: Several studies using magnetic resonance imaging (MRI) to evaluate the lumbar spine in adults have shown a large prevalence of degenerative changes in asymptomatic subjects; however, studies in pediatric patients are scarce. Those studies have suggested a lower rate of degenerative findings in adolescents than in adults, but the actual prevalence of MRI findings in the pediatric population has not yet been determined. We aimed to determine the prevalence of degenerative changes in the lumbar spine of pediatric patients using abdominal and pelvic MRI as the screening tool. METHODS: We studied 103 patients (mean age 6.6 years) who were evaluated with abdominal and pelvic MRI for indications that were not spine related. The entire lumbo-sacral spine was evaluated to detect the presence of disc degeneration (DD), disc displacement, anular rupture with high-intensity zone (HIZ) and Modic changes. RESULTS: In our population, 10.7 % [4.9-16.5] had at least one disc classified as Pfirrmann 2, and no patients presented discs classified as Pfirrmann 3, 4 or 5; patients exhibiting discs classified as Pfirrmann 2 were significantly older than patients who had only Pfirrmann 1 discs. The prevalence of disc bulging was 1 % [0-2.9]. No patients presented disc herniation (including protrusion or extrusions); additionally, no patients exhibited HIZ or Modic changes. CONCLUSIONS: Incidental findings related to DD are very uncommon at this early age, in contrast to findings described in adults or later in adolescence.

The objective of this study was to determine the prevalence of impacted maxillary canines and analyze variables associated with its retention in panoramic radiographs. Manual and Retrospective observational study of 16,835 records. A sample of 1,353 panoramic radiographs was obtained. The variables measured were canine angle, distance from the canine apex to occlusal plane, vertical and horizontal canine location. For reliable measurement an intra class Fleiss and Cohen correlation coefficient was used (0.997). Prevalence was 2.3%. 31 subjects had one or both retained canines. Average age 10.77±2.45, 61.3% were women. 64.5% presented unilateral retaining of which the largest percentage was left. A total of 41 retained canines were observed. Distance to occlusal plane 19 mm on average. In relation to the vertical location the highest percentage (48.7%) was found in the apical third. Regarding the horizontal location the highest percentage (77.6%) was found in sectors 1, 2 and 3. When analyzing the canine angle it was found that 83% measured 31 degrees or more. Radicular resorption was observed in 2 lateral incisors. The prevalence found is similar to that reported in the international literature. It occurred more frequently in women and left unilateral both not statistically significant.
El objetivo de este trabajo fue determinar la prevalencia de dientes caninos maxilares retenidos y analizar variables asociadas a su retención, en radiografías panorámicas. Se realizó un estudio observacional retrospectivo y manual de 16.835 fichas. Se obtuvo una muestra de 1.353 radiografías panorámicas. Las variables medidas fueron ángulo del canino, distancia de la cúspide del canino al plano oclusal, localización vertical y horizontal del canino. Para la fiabilidad de las mediciones se usó el coeficiente de correlación intraclase de Fleiss & Cohen (0,997). La prevalencia fue 2,3%. Treinta y un sujetos presentaron 1 o ambos caninos retenidos. La edad promedio fue 10,77±2,45, y el 61,3% fueron mujeres. El 64,5% presentó retención unilateral, principalmente del lado izquierdo. Se observó un total de 41 caninos retenidos. La distancia al plano oclusal en promedio fue 19 mm. En relación a la localización vertical, el mayor porcentaje (48,7%) se encontró en el tercio apical. Respecto a la localización horizontal, el mayor porcentaje (77,6%) se encontró en los sectores 1, 2 y 3. Al analizar el ángulo canino, se encontró que 83% midió 31 o más. Se observó reabsorción radicular de dos incisivos laterales. La prevalencia encontrada es similar a la reportada en la literatura internacional. La retención se presentó con mayor frecuencia en mujeres y de manera unilateral en el lado izquierdo, pero en ambos casos no es significativa.

Tourette syndrome (TS) and tic disorders represent events of familiar magnitude characterized by involuntary movements and/or vocalization. To determine the prevalence of TS/tic disorders we studied a sample of 762 subjects (388 M, 374 F), between 1992 and 1997, age 6 to 43 years old, taken out of a population of 10,155 subjects (4,918 M, 5,237 F; age: 3-56 years old). A structured 4-item questionnaire, direct interview (multistaged), >1 yr follow-up, were used. 9,565 subjects (4,614 M, 4,951 F) sent back the questionnaires, 3,354 of these (1,671 M, 1,683 F) with positive answers to tics. 42 subjects (31 M, 11 F, age: 7-21 years old, mean: 11 years old) met the DSM-III-R criteria. The total minimal prevalence of TS is 0.43%, with a 3:1 ratio male/female. The minimal prevalence of chronic tic disorder is 2.27%. The total minimal prevalence for tic disorders at all is 2.91%. No special education students participation.
Síndrome de Tourette e transtornos de tiques representam eventos de magnitude familiar caracterizados por movimentos involuntários e/ou vocalização. Para determinar a prevalência de TS/transtornos de tiques, estudamos uma amostra de 762 indivíduos (286 M, 376 F), entre 1992 e 1997, de 6 a 43 anos de idade, retirados de uma população de 10.155 indivíduos (4.918 M, 5.237 F, idade: 3-56 anos). Questionário de avaliação inicial (4 itens), entrevista direta, follow-up >1 ano, foram utilizados. 9.565 indivíduos (4.614 M, 4.951 F) retornaram seus questionários, 3.354 (1.671 M, 1.683 F), com respostas positivas para tiques. 42 sujeitos (idade 31 M, 11 F, 7-21 anos, média: 11 anos) preencheram os critérios diagnósticos do DSM-III-R. A prevalência total mínima para TS é de 0,43% (3 M:1 F), e para transtornos de tiques crônicos é de 2,27%. A prevalência total mínima para transtornos dos tiques é 2,91%. Nenhuma participação de estudantes de classe especial.

Introducción: Los médicos tienen mayores tasas de suicidio en comparación con la población general. Este riesgo tiende a incrementarse incluso a partir del inicio de la formación de pregrado en medicina. Existen pocos estudios que evalúen la frecuencia de conductas suicidas en estudiantes de pregrado de medicina, especialmente en Latinoamérica. Objetivo: Determinar la prevalencia de vida y factores asociados con la ideación suicida e intentos suicidas en una muestra de estudiantes de medicina de Bucaramanga, Colombia. Materiales y métodos: Se condujo un estudio observacional analítico de corte transversal, para determinar la prevalencia de vida de ideación suicida e intentos suicidas, en una muestra no probabilística de estudiantes de medicina matriculados en las 3 facultades de medicina de Bucaramanga. El cuestionario autoaplicado fue respondido de forma voluntaria y anónima por los participantes. Las versiones validadas de las escalas CES-D y CAGE fueron utilizadas para evaluar síntomas depresivos y uso problemático de alcohol, respectivamente. Se generó un modelo multivariado de regresión logística, con el fin de ajustar los estimadores de las variables asociadas con el desenlace «ideación suicida alguna vez en la vida¼. Resultados: La muestra de estudio estuvo formada por 963 estudiantes. El 57% (n = 549) de los participantes fueron mujeres. El promedio de edad fue de 20,3 años (DE 2,3 años). En relación con la prevalencia de ideación suicida, el 15,7% (n = 149) de los estudiantes informó haber tenido por lo menos un episodio de ideación suicida serio a lo largo de la vida. El 5% (n = 47) señaló haber realizado por lo menos un intento suicida. El 13,9% (n = 131) de los estudiantes informó haber ingerido antidepresivos durante su entrenamiento médico. Las variables asociadas con la ideación suicida en el modelo de regresión logística fueron: síntomas depresivos clínicamente significativos (OR: 6,9; IC 95%: 4,54-10,4), historia de consumo de sustancias psicoactivas ilícitas (OR: 2,8; IC 95%: 1,6-4,8) y percepción del regular o mal rendimiento académico durante el último año (OR: 2,2; IC 95%: 1,38-3,63). El modelo de regresión logística clasificó correctamente al 85% de los sujetos con antecedente de ideación suicida. Conclusión: La ideación suicida es un fenómeno de frecuente ocurrencia en estudiantes de medicina. Es necesario que las facultades de medicina establezcan programas de detección e intervención temprana que permitan disminuir la probabilidad de ocurrencia de desenlaces negativos.
Introduction: It is well documented that physicians have higher rates of suicide than the general population. This risk tends to increase even from the beginning of undergraduate training in medicine. There are few studies evaluating the frequency of suicidal behaviors in undergraduate medical students, particularly in Latin America. Objective: To determine the lifetime prevalence and the variables associated with suicidal ideation and suicide attempts in a sample of medical students from the city of Bucaramanga, Colombia. Materials and methods: An analytical cross-sectional observational study was conducted to determine the lifetime prevalence of suicidal ideation and suicide attempts in a nonrandom sample of medical students enrolled in three medical schools in Bucaramanga. A self-administered questionnaire was voluntarily and anonymously answered by the participants. Validated versions of the CES-D and CAGE scales were used to assess the presence of depressive symptoms and problematic alcohol use, respectively. A multivariate logistic regression model was generated in order to adjust the estimates of variables associated with the outcome «suicidal ideation in life¼. Results: The study sample consisted of 963 medical students, of which 57% (n = 549) of the participants were women. The average age was 20.3 years (SD = 2.3 years). Having had at least one episode of serious suicidal ideation in their lifetime was reported by 15.7% (n = 149) of the students, with 5% (n = 47) of the students reported having made at least one suicide attempt. Having taken antidepressants during their medical training was reported by 13.9% (n = 131) of the students. The variables associated with the presence of suicidal ideation in the logistic regression model were: clinically significant depressive symptoms (OR: 6.9, 95% CI; 4.54-10.4), history of illicit psychoactive substance use (OR 2.8, 95% CI; 1.6-4.8), and perception of poor academic performance over the past year (OR: 2.2, 95% CI; 1.4-3.6). The logistic regression model correctly classified 85% of the subjects with a history of suicidal ideation. Conclusion: Suicidal ideation is a frequently occurring phenomenon in medical students. Medical schools need to establish screening procedures for early detection and intervention of students with emotional distress and suicide risk.

RESUMEN
As características do trabalho na Estratégia Saúde da Família (ESF) são complexas e ainda há poucos estudos que abordam a temática. OBJETIVO: descrever características sociodemográficas e do trabalho e a prevalência de Distúrbios Psíquicos Menores (DPM) e de positivos ao teste CAGE (abuso no consumo de álcool) entre médicos, enfermeiros e cirurgiões-dentistas da ESF de Feira de Santana, Bahia. METODOLOGIA: estudo epidemiológico de corte transversal que utilizou questionário padronizado, não identificado, para descrever: o perfil sociodemográfico; as características do trabalho na ESF; a saúde mental e o uso abusivo de bebidas alcoólicas utilizando o Self Reporting Questionnaire (SRQ-20) e o Teste CAGE,. Os dados foram analisados no Statistical Package for Social Scince (SPSS). RESULTADOS: Entre os 152 respondentes, que correspondem a uma taxa de resposta de 86,4%, a prevalência de DPM foi de 16,0%. Entre os médicos, foi de 17,4%; entre os enfermeiros, de 15,5%; e 15,2% entre os cirurgiões-dentistas. Quanto ao uso abusivo de bebida alcoólica, os médicos apresentaram prevalência de 5,0% e os cirurgiões-dentistas de 7,7%. Os resultados apontaram o predomínio do sexo feminino, de adultos jovens, casados, com vínculo cooperativado, carga horária semanal elevada e mais de um vínculo empregatício. CONCLUSÃO: A prevalência de DPM e de positivos ao teste CAGE observada na população estudada foi menor do que a encontrada em outros estudos.
To date, few studies have looked into the complex aspects of work at the Family Health Strategy (FHS). OBJECTIVE: To describe sociodemographics, work aspects, Minor Psychiatric Disorders (MPD), and CAGE positivity (alcoholism) among physicians, nurses and dentists working with FHS in Feira de Santana (Bahia, Brazil). METHODS: Cross-sectional study using standard questionnaires (SRQ-20 and CAGE) to collect anonymous information on the sociodemographic profile, work aspects, mental health, and alcohol consumption. Data were analyzed with SPSS. RESULTS: Based on 152 respondees (response rate: 86.4%), the overall prevalence of MPD was 16.0% (physicians=17.4%, nurses=15.5%, dentists=15.2%). The prevalence of alcoholism was 5.0% among physicians and 7.7% among dentists. The characteristics "female", "young adult", "married", "affiliated to a cooperative", "long work week" and "more than one job" predominated in this population. CONCLUSION: the prevalence of MPD and CAGE positivity was smaller in our sample than in other similar studies.
