Evaluation of normal variants of circle of Willis at MRI

Background: Anatomy of circle of Willis (COW) shows extensive variations in different individuals and signifies the causation and presentation of clinical disease. The present study aims to evaluate the different anatomical variations of the Circle of Willis (COW) in general population, using magnetic resonance (MR) 3D-time of flight angiography and to correlate the observations with age and gender characteristics.Methods: This observational clinical study was conducted January 2013 to March 2014 in 503patients who were referred for MRI – Brain. MRI (Philips 1.5 Tesla magnet) with routine brain sequences along with 3D –TOF MRA was done in all patients. The anatomical variants of the anterior and posterior components of the COW were studied. The complete COW was assessed and the diameters of all the components were measured. The correlation between the vessel diameters in relations to age and gender were evaluated.Results: The mean age group of study participants was 42 years. Male dominance was seen among participants (57.1%). The complete configuration of the circle was seen in 31.6% of population. Most common anterior variant is type A (normal anterior configuration) with a prevalence of 52.9% and posterior variant is type K with a prevalence of 32.9%. Average diameters of the proximal vessels supplying the COW were larger in the older age subjects (centripetal vessels, the right and left ICA s and BA). Statistically significant differences between the mean vessel diameters between males and females were seen in the ICA-RT, ICA-LT, and PCOA-LT.Conclusions: The present study showed great variability of the anatomy of the COW in asymptomatic person. Various variants of COW can be picked up by MRA which is safer and non-invasive when compared with CTA / DSA. Knowledge of these variations would help in planning surgical procedures as well as preventing unwanted interventions.

Aim: Foramen mentale is the anatomical formation in which the vein and nerve package feeds and provides sensory innervation to the chin and lower anterior lip area. During implant surgery and osteotomy operations, it is important to know the anatomical morphometric characteristics because of mental nerve damage. This study aims to determine whether mental foramen differ depending on age and gender. Method: 100 patients (50 females-50 males) who applied to neu faculty of dentistry and received kıbt for various reasons between 2020-2021 were included in the study. spss program was used for statistical analysis. a p value of <0.05 was considered significant. Results: The mean superoinferior diameter of the right and left mental foramen was 3.20 mm and 3.21 mm, respectively. The mean values were 3.12 mm and 3.18 mm for right and left mental foramen, respectively. It was found that the right and left mental foramen are located between the 1st and 2nd premolars. Anteroposterior and superoinferior diameters of the right and left foramen do not differ according to the localization of the mental foramen (p> 0.05). It was found that the parameters except the superoinferior diameter of the right mental foramen did not show a statistically significant difference according to gender (p> 0.05). It was found that the right mental foramen superoinferior diameter of males was statistically higher than females. (p <0.01). It was found that the anterosuperior and superoinferior diameters of the mental foramen did not vary according to age (p> 0.05). Conclusion: According to the result we obtained from this study, it was determined that the superoinferior diameter of the mental foramen was higher in men. This result will guide for those working in the field of anatomy, oral maxillofacial surgeons and oral maxillofacial radiologists.

Objectives: The objective of our study was to examine the changes in the inclination and Alsberg angles of the femur in terms of age and gender. Methods: The present study was conducted on X-Ray images of 208 healthy individuals (103 males and 105 females) admitted to Bolu Abant Izzet Baysal University, Orthopedics and Traumatology Clinics. Both genders were separated into 3 different age groups. Statistical analyses were made to determine the difference between the gender and age groups. Results: The mean inclination angle of the femur was 132.88±7.08º on the right-side and 130.27±7.81º on the left. The mean Alsberg angle of the femur was 42.07±7.04º on the right-side and 41.43±7.03º on the left. The inclination angle was significantly higher in males than females on both sides and was significantly lower in 41–60 age group. The Alsberg angle was also significantly higher in males than females in 21–40 age group. Conclusion: The Alsberg angle is positively related with inclination angle, and subject to change by age. Knowing how IA and AA will be affected by age and gender and knowing the relation between these two angles will help to take a more accurate approach while evaluating and managing the follow up of a patient undergoing total hip arthroplasty, reconstructive surgery or planning physical theraphy.

Symptomatic Stenosis

Foetal-type posterior circle of Willis is a common anatomical variation with a variable degree of vessel asymmetry. In patients with this abnormality, carotid endarterectomy (CEA) may create cerebral hypo-perfusion intraoperatively, and this may be underestimated under general anaesthesia. There is currently no evidence that anatomical variations in the circle of Willis represent an independent risk factor for stroke. Moreover, there is a paucity of data on treating patients with such anatomical variations and co-existing ICA stenosis. We present a case of CEA under local anaesthesia (LA) in a 52-year-old female patient with symptomatic stenosis of the right ICA and coexistent foetal-type posterior circle of Willis. There were no post-operative complications and she was discharged free from symptoms. She was seen again 3 months later and was free from complications. This case higlights that LA should be strongly considered to enable better intra-operative neurological monitoring in the event of foetal-type posterior circle of Willis.

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.

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.

Diagnostic And Prognostic Value

Background and aims The etiology and pathophysiology of coronary artery ectasia (CAE) has not been fully elucidated. A rapid rise in plasma copeptin has been observed in cardiovascular diseases, stroke, sepsis, and shock. This increase has diagnostic and prognostic value. The aim of this study was to investigate whether copeptin has a relationship with CAE. Methods This observational prospective study was carried out between October 2012 and March 2013 in the cardiology catheter laboratory with the inclusion of 44 subjects with a diagnosis of CAE and 44 age- and gender-matched individuals with normal coronary arteries. Blood samples obtained from the patients were stored at −70 °C until analysis and copeptin levels in sera were measured by ELISA. Results This study comprised 88 study participants, among whom 44 were patients meeting ectasia criteria [mean age: 58.0 ± 11.5 years; 59% (n = 26) male], and 44 were control subjects with angiographically normal coronary anatomy [mean age: 49.2 ± 10.1 years; 30% (n = 13) male]. Copeptin levels were similar between the groups (p > 0.05). In addition, there was no correlation between copeptin levels and CAE. Conclusion In this study, it is examined that copeptin levels were not elevated in CAE patients.

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.

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.
