Clinical implications in orbital and pterional flap surgeries as well as radioimaging studies to determine topographical prevalence and characterization of meningo-orbital foramen in orbits of the Indian population / Implicaciones clínicas en cirugías de colgajo orbitario y pterional, así como estudios de radioimagen para determinar la prevalencia topográfica y la caracterización del foramen meningoorbitario en órbitas de la población india

SUMMARY: The pear-shaped bony orbit connects with intracranial cavity via foramina's and fissures. The Meningo-orbital Foramen (MOF) is usually present in greater wing of sphenoid close to lateral edge of Superior orbital fissure. It provides a route for an anastomosis between the orbital branch of the middle meningeal artery (MMA) and recurrent meningeal branch of Ophthalmic Artery (OA) and hence, risk of damage during surgeries can occur. To verify occurrence and location, with morphology of MOF in dry orbits and the impending clinical hazards in surgeries pertaining to the orbit, document and analysis it to determine a standardized guideline. The presence for MOF was studied in 446 dry orbits with its location from the supra orbital margin (SOM), front zygomatic suture (FZS), the lateral tubercle of Whitnall (WT)and the lateral end of superior orbital fissure (SOF) along with its patency, laterality and number of foramina's present. Nylon probes, long divider/pins, compass and Vernier callipers was used to check the patency and various parameters. The study noted the percentage prevalence of MOF as 69 % with communication with middle cranial fossa (MCF) being 76 % of 69 % and the average distance from SOM, FZS, WT and lateral end of SOF being 35.58 mm, 24.9 mm, 26.6 mm and 0.92 mm. On comparison with various population studies, certain similarities and differences with regards to different parameters were noted. Prevalence of MOF was mostly unilateral and showed multiple foramina, that can act as channels for arteries, a variant of MMA or OA, that supply orbital structures or tumour growths. Thus, awareness of this variation is of prime importance to ophthalmologists and neurosurgeons as well as interventional radiologists, in preventing haemorrhagic condition which could further raise the difficulties in operative procedures and surgical outcomes.

RESUMEN: La órbita ósea en forma de pera se conecta con la cavidad intracraneal a través de forámenes y fisuras. El foramen meningoorbitario (MOF) suele estar presente en el ala mayor del esfenoides cerca del margen lateral de la fisura orbitaria superior. Proporciona una ruta para una anastomosis entre la rama orbitaria de la arteria meníngea media (MMA) y la rama meníngea recurrente de la arteria oftálmica (OA) y, por lo tanto, puede ocurrir riesgo de daño durante las cirugías. Para verificar la ocurrencia y ubicación, con la morfología de MOF en órbitas secas y los peligros clínicos inminentes en cirugías de la órbita, documentarlo y analizarlo para determinar una pauta estandarizada. Se estudió la presencia de MOF en 446 órbitas secas desde el margen supraorbitario (MOS), sutura cigomática frontal (FZS), el tubér- culo lateral de Whitnall (WT) y el extremo lateral de la fisura orbitaria superior (SOF) junto con su permeabilidad, lateralidad y número de forámenes presentes. Se utilizaron sondas de nailon, divisores / pasadores largos, brújula y calibradores Vernier para comprobar la permeabilidad. En el estudio se pudo observar que la prevalencia porcentual de MOF era del 69 %, siendo la comunica- ción con la fosa craneal media (MCF) del 76 % del 69 % y la distancia promedio desde SOM, FZS, WT y el extremo lateral de SOF era de 35,58 mm, 24,9 mm, 26,6 mm y 0,92 mm. En comparación con varios estudios de población, se observaron ciertas similitudes y diferencias con respecto a diferentes parámetros. La prevalencia de MOF fue mayoritariamente unilateral y mostró múltiples forámenes, que pueden actuar como canales para las arterias, una variante de MMA u OA, que irrigan estructuras orbitarias o crecimientos tumorales. Por lo tanto, la conciencia de esta variación es de primordial importancia para los oftalmólogos y neurocirujanos, así como para los radiólogos intervencionistas, en la prevención de una enfermedad hemorrágica que podría aumentar aún más las dificultades en los procedimientos y los resultados quirúrgicos.

Age wise distribution of coronary artery disease risk factors.

Background: Coronary Artery Disease (CAD) is the leading cause of death in most industrialised countries (about one-third of all deaths) and somewhat low incidence is observed in the developing countries. Aims & Objective: To study age wise distribution of Coronary Artery Disease risk factors. Material and Methods: The data for this study was collected from Baroda Heart Institute & Research Centre (BHIRC). The total 208 patients were considered for study of CAD. Results: The majority of our patients were from age group of 60-69 years i.e. 67 (32.21%) and only 10 patients (4.32%) were in the age group of ≥80 years. Amongst all patients, 93.27% were lacking exercise, 39.42% were hypertensive, 28.85% were obese, 27.88% diabetic, 10.58% had family history of CAD and 5.28% were smokers. Conclusion: It is essential to identify CAD risk factors amongst the Indians to tackle the problem. So this study would be of great help in this direction.

Ultrasonic measurement splenic size of normal & comparison with various medical disorders involving spleen in paediatric Indian population.

Intorduction:The present study was conducted in the departments of Anatomy, Radiology and Paediatrics at a General Public Charitable Hospital, Mumbai. Method: The study group consisted of 160 children of both sexes, who were referred to the Radiology department for ultrasonography. Out of these 160 chidren, 80 underwent sonography for abdominal and/or pelvic problems unrelated to the spleen and 80 children were suffering from medical disorders related to spleen i.e. 55 patients of thalassemia major, 13 patients of malaria, 9 patients of typhoid and 3 patients of portal hypertension. The splenic length was measured by using a commercially available real time ultrasound system with a TOSHIBA ECOCEE USG SYSTEM particularly by using the convex probe. Result: In the present study in abnormal spleen group, there is a strong correlation between weight and splenic size, and between age and splenic size, there is a partial correlation between height and the splenic size. In all the children with clinically obvious splenomegaly, the splenic length exceeded at least 2 cm than the normal splenic length at that particular age.Conclusion : This study shall stand as a good reference to Radiologists, Paediatricians, Haematologists and Physicians in an undiagnosed and complicated cases and will also helpful to determine the mode of treatment in thalassemia major with splenomegaly.
