ABSTRACT
The aim of this study was to analyze the prevalence of transmigrated canines in a Spanish population by evaluating their clinical and radiological characteristics. The descriptive observational study obtained 6840 orthopantomographs from all patients seeking dental care in the years 2017-21 via the Patient Reception Service and Dentistry Service at the Faculty of Dentistry at the Complutense University of Madrid and the Central Hospital of the Red Cross of Madrid (Spain). In total, 52 patients presented transmigrated canines, establishing a prevalence of 0.76%. This sample comprised 28 women and 24 men. Whenever a transmigrated canine was identified, a CBCT scan was obtained and used to evaluate the clinical and radiological variables associated with canine transmigration. The predominant side of the transmigration was the left (57.69%) compared to the right side (42.30%). The position of the canine, in order of frequency, according to the Mupparapu classification, corresponded to type IV (42.30%), type II (36.53%), type I (15.38%), and type V (5.76%), with no type III transmigrations found. Clinical manifestations were only recorded in 17.30% of cases, and 11.53% of the radiological findings showed the presence of tooth cysts that were confirmed by histopathological studies. Other impactions, in addition to the transmigrated canine, were found in five patients (9.61%), with the majority being the presence of third molars.
ABSTRACT
(1) Objectives: The aim is to measure the influence of different intraoral (crowding and molar inclination) and extraoral (surface material and ambient light) conditions on the efficacy and efficiency of intraoral scanning. (2) Methods: In a controlled in vitro experimental study, the samples were divided into six groups showing two types of intraoral conditions-lower incisor crowding (groups 1-3) and lower molar mesial tipping (groups 4-6). Each modified model was replicated using three types of materials with different light-absorption properties (n = 18 models). Each sample was scanned 30 times at light intensities of 0.0, 1800, or 3600 l×, yielding 3240 scans. Scanning efficiency (digital acquisition; scanning chair-time; and scanning failures) and scanning efficacy (undetected volume) were assessed using virtual superimpositions and Mecano Equate software. The intra- and interobserver error and reliability of the method were calculated and data analyses were performed using the t-test, paired t-test, and one-way analysis of variance (p < 0.05). (3) Results: Digital acquisition was influenced by the degree of crowding and molar inclination (p < 0.05). The scanning surface material affected the efficacy and efficiency, which were lower with a calcium sulfate hemihydrate A modified compound scanning surface (p < 0.05). Higher intensities of ambient light in the scanning room were associated with reduced scanning efficacy (p < 0.05). Moreover, the scanner showed greater amounts of undetected volume as the degrees of crowding and mesial tipping of the lower second molar increased over 25°, with mean error values of 0.97 mm3 and 1.12 mm3, respectively. (4) Conclusions: For scanning procedures employing digital acquisition, differences in the degrees of crowding and mesial tipping of the lower second molar, scanning surface material, and external light source intensity influence the efficacy and efficiency of the scanning procedures, scanning chair-time, scanning failures, and undetected volume.
ABSTRACT
BACKGROUND: Surveys report low frequencies of sexual history (SH) obtained in primary care. Sexually transmitted infections incidence can be reduced with timely screening. It is important to determine whether providers obtain thorough SH and to identify needs for improvement. AIM: To evaluate the frequency and depth of SH taking in primary care. METHODS: In this cross-sectional cohort study, 1,017 primary care visits were reviewed (1,017 adult patients, female 55.26%). 417 patients were seen by male providers and 600 patients were seen by female providers. Multivariate ordered and logit models were deployed. MAIN OUTCOME MEASURES: The primary outcome measures included SH taking rates and completeness based on the 5 P model as described by the Centers for Disease Control and Prevention. RESULTS: All components of SH were explored in 1.08% of visits. Partial SH was obtained in 33.92% of visits. No SH was taken in the majority of visits (65%). SH was more likely to be taken from female patients than from male patients (P < .001), and was less likely to be obtained from older patients as compared to younger individuals (P < .001). There was no significant difference in SH taking between male and female providers (P = .753). The provider title and the level of training were found to be independent predictors of SH taking (P < .001). CLINICAL IMPLICATIONS: The results of this study highlight an unmet need for more comprehensive and consistent SH taking amongst providers, particularly in high-risk settings, so that SH can be used as a valuable tool in preventive care. STRENGTHS & LIMITATIONS: To the best of our knowledge, this is the largest study to date examining SH taking in the primary care setting. Limitations include the retrospective study design, lack of generalizability to other hospitals, and inconsistencies in available data. CONCLUSION: The SH taking rates in primary care clinics are globally low with a variation depending on the provider position or level of training, provider gender, and patient age.

Cancer is the first cause of death by disease in childhood globally. The most frequent types of cancers in children and adolescents are leukemias, followed by brain and central nervous system tumors and lymphomas. The recovery rate of cancer in children is around 80% in developed countries and up to 30% in developing countries. Some of the main causes of complications in children and adolescents with cancer are respiratory viral infections, mainly in bone marrow-transplanted patients. Respiratory viruses have been detected in the bronchoalveolar lavage or nasal wash specimens from cancer patients with or without respiratory illness symptoms. Human metapneumovirus (HMPV) is within the ten most common viruses that are encountered in samples from pediatric patients with underlying oncology conditions. In most of cases, HMPV is found as the only viral agent, but co-infection with other viruses or with bacterial agents has also been reported. The discrepancies between the most prevalent viral agents may be due to the different populations studied or the range of viral agents tested. Some of the cases of infection with HMPV in cancer patients have been fatal, especially in those who have received a hematopoietic stem cell transplant. This review seeks to show a general view of the participation of HMPV in respiratory illness as a complication of cancer in childhood and adolescence.
ABSTRACT
La diastematomielia es una anomalía del desarrollo del tubo neural, caracterizada por una división sagital de la médula espinal. Los síntomas son variados y puede cursar con dolor, trastornos de la marcha, escoliosis, deformidad de los pies, alteraciones del control de esfínteres, estigmas cutáneos, aumento de la tensión muscular e hidrocefalia, entre otros. En ocasiones es asintomática. Se presenta un caso clínico de un varón de 24 años, que sufre caída desde 4 m de altura y sufre fractura en columna lumbar L2 (AOSpine A3, N0), con diastematomielia en L1 de tipo I como hallazgo incidental y hemivértebra en T12. Se manejó con estabilización con tornillos pediculares con buena evolución. El manejo de estos pacientes debe ser individualizado. Los tornillos pediculares ofrecen resultados satisfactorios con bajo riesgo de lesión neurológica. Nivel de evidencia clínica Nivel IV.
Diastematomyelia is an abnormality of the development of the neural tube, and is characterised by a sagittal division of the spinal cord. is the symptoms vary and may include pain, gait disorders, scoliosis, deformity of the feet, changes in sphincter control, skin stigmas, increased muscle tension, and hydrocephalus, among others. It is occasionally asymptomatic. The case is reported of a 24-year-old male, suffering a 4-metre fall and a lumbar spine fracture L2 (AOSpine A3, N0), with L1 type I diastematomyelia as an incidental finding and hemivertebra in T12. It was managed with stabilisation with pedicle screws, with a good outcome. The management of these patients must be individualised, the pedicle screws offer satisfactory results with low risk of neurological damage.
