Epidemiological Significance

SUMMARYRates of acquisition and loss of Brugia malayi microfilaraemia were estimated using the parasitological data of a cohort of population in Shertallai, South India. The rate of acquisition of microfilaraemia was found to be dependent on age but not gender. The decline in the rate of acquisition of microfilaraemia in adults above 35 years could be due to the development of acquired immunity. The mean reproductive lifespan for the periodic Brugia malayi adult female worm was estimated to be 34 years and it was independent of host age and gender. The age-specific estimated proportion of population at risk (microfilaria carriers who lost their microfilaria in course of time) of developing lymphoedema approximately mirrored the observed age specific prevalence of lymphoedema in the study-population. On an average, 99% of population at risk developed manifestations of disease. The estimated population at risk of developing disease in different endemic areas is compared and its epidemiological significance is discussed.

Introduction: Proximal humerus fractures (PHF) constitute the majority of the most common osteoporotic fractures. Bone density measurements can affect treatment methods and outcomes. This study was aimed to investigate the effect of osteoporosis values, measured from direct radiographs, on fracture type, surgical outcomes. Methods: 248 patients over 50 years of age who presented to Mersin City Hospital between 2017 and 2020 with proximal humeral fractures were retrospectively evaluated. The age and gender of the patients and the fracture types were evaluated according to the AO classification system from the direct radiographs obtained at the time of admission were recorded. The Tingart cortical thickness and deltoid tuberosity index (DTI) measurements were used to assess osteoporosis status in all patients. Postoperative and follow-up radiographs of 45 patients, treated with fixed-angle proximal humeral locking plate, were evaluated for radiographic results and their correlations with osteoporosis measurements were examined. Results: According to the demographic characteristics of the patients, 171 patients were female and 77 patients were male (F/M: 3/1), and mean age was 69.2 ± 11.66 (50-95). Considering the bone quality parameters in all patients, the mean Tingart value was 5.8 ± 1.6 mm and the mean DTI was 1.43 ± 0.17, where there was a correlation between the Tingart value and DTI (r = 0.810 and p < 0.001). Although there was a statistically significant relationship between the osteoporosis parameters and age and gender (p < 0.001 and p = 0.023, respectively), main AO fracture types were not related to osteoporosis (p < 0.05). In the operated group (n = 48, 19%), 19 patients (42%) showed poor outcomes, which were not associated with age and osteoporosis parameters. Conclusion: This study was concluded that osteoporosis parameters differ between genders and age groups in patients with PHF, however osteoporosis is not the main factor affecting the fracture type and surgical outcomes.

The size of criminal populations is unknown, and policy decisions are typically based only on the number of offenses and offenders that come to the attention of the criminal justice system. However, the size of criminal populations may follow different trends than what is observed in official data. We use a regression-adjusted capture–recapture model to estimate the number of people at risk of arrest for offenses involving amphetamine-type stimulants (ATS) from arrests and rearrests occurring in Quebec, Canada, controlling for year of first arrest, age, and gender. The 4,989 individuals arrested were the visible part of an estimated 42,541 [36,936, 48,145] individuals otherwise at risk of arrest (12%). Additional results show that trends in criminal populations and risks of arrest vary across offense type and drug classifications.

ABSTRACT Objectives The purpose of the study was to analyze the frequency and distribution of gingival lesions in MR Ambedkar Dental College, Bengaluru. Materials and methods The material included the biopsies of all localized reactive hyperplastic lesions (LRHL) of the gingiva stored in the department's database (1995-2011). The lesions were analyzed according to their location and the patient's age and gender. The findings were compared with other published studies on reactive lesions. Results A total of 260 reactive lesion biopsies were accessed. focal fibrous hyperplasia (FFH) was the most common (38.5%), followed by pyogenic granuloma (PG) (34.6%), peripheral ossifying fibroma (POF) (17.7%) and peripheral giant cell granuloma (PGCG) (9.2%). The mean age of the patients was 33 years, with a range varying from 9 to 80 years. The LRHL occurred more commonly in females except focal fibrous hyperplasia, which showed male predilection. PG and POF were more common in the maxilla and FFH as well as PGCG were more common in the mandible. Conclusion This study indicates some differences in age and gender distribution as well as in location between the different lesions. The results of this study differ from those of other studies and the data presented here can be used as a guide for further multicenter studies. How to cite this article Ramu S, Rodrigues C.

The Relationship

Aim. The aim of the present study was to examine the relationship between articular eminence inclination, height, and thickness of the roof of the glenoid fossa (RGF) according to age and gender and to assess condyle morphology including incidental findings of osseous characteristics associated with osteoarthritis (OA) of the temporomandibular joint (TMJ) using cone beam computed tomography (CBCT).Materials and Methods. CBCT images of 105 patients were evaluated retrospectively. For articular eminence inclination and height, axial views on which the condylar processes were seen with their widest mediolateral extent being used as a reference view for secondary reconstruction. Condyle morphology was categorized both in the sagittal and coronal plane.Results. The mean values of eminence inclination and height of males were higher than those of females (P<0.05). There were significant differences in the RGF thickness in relation to sagittal condyle morphology. Among the group of OA, the mean value of the RGF thickness for “OA-osteophyte” group was the highest (1.59 mm), whereas the lowest RGF values were seen in the “OA-flattening.”Conclusion. The sagittal osteoarthritic changes may have an effect on RGF thickness by mechanical stimulation and changed stress distribution. Gender has a significant effect on eminence height (Eh) and inclination.

Objective: Intelligence profile with age and gender differentials analysis and identification of a battery of subscales of intelligence are important for clinical management of ASD problems among children as well as in facilitating placement for remedial and educational services. Hence, this study aims to explore the intelligence quotient (IQ) profile among children with ASD and identify the most important subscales that predict the IQ. Method: The study is based on data collected through an exploratory study of 100 children aged between 3 and 13 years, who were referred to the department of child health and development in a tertiary hospital in Oman between June 2016 - June 2019. Results: Among the participants of this study, 79% were males, resulting in a male: female ratio of 4:1. The mean of full-scale IQ was found to be 68.58±18. The mean of non-verbal IQ (73.5±17.5) was significantly higher than the mean of verbal IQ (65.46±17.6). More than half (61%) of the children were observed to have mild to moderate impairment in IQ level. Conclusion: Age and gender showed no significant association with intelligence level. Regression analysis identified non-verbal fluid reasoning, non-verbal visual-spatial processing, non-verbal working memory and verbal knowledge as the significant predictors of total IQ. The significant dimensions of verbal and non-verbal IQ identified in this study can be used to evaluate difficult cases.   Keywords: Autism, Oman, Intellectual profile, prediction

Purpose: to assess specificities of course of the long­QT syndrome in children before and after implantation of cardioverter­defibrillator (ICD), and optimization of indications to ICD­therapy.Materials and methods. We included in this study 48 children with long­QT syndrome from 44 unrelated families (28 boys and 20 girls), who underwent ICD implantation at the mean age 11.8±3.8 years. Mean duration of follow­up after implantation was 5.2±2.8 years. Data from these children were compared with those from 59 children of comparable age and gender with long­QT syndrome from 46 unrelated families receiving antiarrhythmic therapy (β­adrenoblockers). We assessed clinical and electrocardiographic characteristics of the disease obtained at initial visit and their dynamics thereafter.Results. Children with long­QT syndrome and ICD were mainly probands with interval QT longer than 500 ms, recurrent syncope and often history of sudden cardiac arrest requiring high doses of β­adrenoblockers for control of ventricular tachyarrhythmias.Conclusion. ICD implantation is an effective and safe method both of primary and secondary prevention of sudden cardiac death in children with long­QT syndrome.

The Impact

AbstractThere is a great deal of literature on contributing environmental factors of soundscape, the perception of the acoustic environment by humans in context. Yet the impact of some contextual and person-related factors is largely unknown. From the questionnaire, adapted from ISO12913-2 and the WHO-5 well-being index, three questions arose: are there differences in Pleasantness and Eventfulness of soundscape among different acoustic environments; are high levels of psychological well-being associated with increased Pleasantness and Eventfulness ratings; and is soundscape Pleasantness and Eventfulness consistent among different age and gender groups? The sample comprised 1180 individual questionnaires, 621 females (52.6%), 532 males (45.1%), mean age 34.95 years ± 15.62, collected from eleven urban locations. Hierarchical clustering analysis was done on the mean of each sound source question for each survey location resulting in three clusters of locations based on sound source composition: Natural-dominant, Traffic-dominant and Mixed-sources. A Kruskal-Wallis was conducted to compare the mean Pleasantness and Eventfulness scores of the three clusters, demonstrating that the soundscape assessment was significantly different depending on sound source composition. Multiple linear regression models were used to analyse the relationship between psychological well-being, age, and gender with soundscape Pleasantness and Eventfulness. Our results indicated first that the positive psychological state was associated with Pleasantness in the all-locations and mixed-sources clusters, and with Eventfulness in the traffic-dominant cluster. Secondly, while age was linked to Pleasantness in all clusters it was merely associated with the Eventfulness in the all-locations cluster. Lastly, gender was associated with Pleasantness only in the all-locations cluster. These findings offer empirical grounds for developing theories of the contextual factors on soundscape.

OBJECTIVE: To evaluate change of the maxillary sinus volume according to patient age and gender by using a 3-dimensional (3-D) reconstruction of computed tomography images. STUDY DESIGN AND SETTING: One hundred seventy-three people (totaling 238 maxillary sinuses) who had undergone paranasal sinus CT scan between December 2000 and November 2003 and had no evidence of inflammation or hypoplasia in the CT finding and had no specific history of paranasal sinus surgery or maxillofacial trauma were retrospectively analyzed. The 3-D reconstruction images were obtained by using a surface-rendering technique (Vworks; CybeMed, Seoul, Korea) on a personal computer. The mean volume of maxillary sinus was evaluated according to patient chronologic age and gender. The ratio of the maximum horizontal and half-horizontal extension for the estimation of the morphological change of maxillary sinus and the degree of descent of the sinus below the nasal floor were evaluated in the 3-D image. RESULTS: The development of the maxillary sinus continued until the 3rd decade in males and until the 2nd decade in females. The mean maxillary sinus volume in early adults was 24,043 mm 3 (males) and 15,859.5 mm 3 (females). There was a significance difference in the sinus volume ( P < 0.05) according to gender, and there was a significant difference in the maxillary sinus volume according to age before it reached maximum. After its maximum growth period, however, there was no significant difference in the volume change of maxillary sinus and the descent below the nasal floor between two adjacent groups. CONCLUSIONS: The growth of the maxillary sinus continues until the 3rd decade in males and the 2nd decade in females. Therefore, a maxillary sinus operation affecting the bony structures before these ages might affect the development of the sinus and needs to be performed carefully
