Anatomical Variations of Corona Mortis in the Anterior Intrapelvic Approach: A Cadaveric Study.

Corona mortis (CMOR) is an anastomotic channel either arterial, venous or both connecting the obturator and external iliac systems excluding aberrant channels in the retropubic space. The goal of this study is to illustrate the type of CMOR via the Anterior Intrapelvic approach (AIP) which has not been studied in tandem. This descriptive observational study was performed in the Department of Anatomy, All India Institute of Medical Sciences, Jodhpur, Rajasthan, India from January 2018 to December 2020. It is a potential culprit for significant haemorrhage in scenarios of pelvic trauma or when sectioned accidentally, augmenting difficult haemostasis behind the superior pubic ramus. Previously reported to be exclusively arterial, the venous variant has now emerged as the more frequent anastomosis. AIP was performed on 31 adult human cadavers of 62 hemipelvises to record variations and statistical analysis of retropubic anastomosis with respect to gender, weight groups and side distribution was done. Corona Mortis was observed in 50(80.6%) hemipelvises. To ramify, venous CMOR and arterial CMOR were exclusively encountered in 25(40.3%) and 10(16.10%) hemipelvises respectively. Males recorded a higher prevalence of CMOR. Despite being a frequent anastomotic variant, it is a rare entity in textbooks. CMOR can potentially alter patient outcome and have serious implications in pelvic surgeries via AIP owing to its easier accessibility. Besides, venous CMOR being more common, a venous bleed is inherently more arduous to manage in the pelvis. A larger calibre, less frequent aberrant channel could also prove to be lethal in its injury. Hence, cadaveric simulation of the technique is paramount to master the technique and to mitigate catastrophic vascular events.

A rare case of persistent pupillary membrane associated with high myopia and amblyopia.

PURPOSE: To present the management of a rare case of persistent pupillary membrane (PPM) associated with high myopia and amblyopia. CASE: A 12-year-old boy presented with progressive diminution of vision in the right eye since childhood. Examination (OD) showed several fine strands of iris attached to the collarette and to the anterior lens capsule with a clump of iris pigment adherent over it. Some of these strands even wrinkled on pupillary contraction. The patient was also examined on slit-lamp.The patient was operated for lens extraction with PCIOL implantation. RESULTS: The patient regained useful vision after surgery. CONCLUSION: This is a rare case of persistent pupillary membrane associated with high axial myopia.

An unusual complex odontoma.

Odontoma, complex type is an agglomerate of all the dental tissues that are characterized by normal histodifferentiation but abnormal morphodifferentiation producing little or no resemblance to normal tooth form. They are usually asymptomatic but often associated with eruption disturbances. An interesting case of unusually large complex odontoma that was associated with pain and an impacted as well as missing molar is reported.

A report on a rare case of Kearns Sayre-like syndrome.

PURPOSE: To report the presentation of a rare case of Kearns-Sayre-like syndrome (KSS) CASE: A 14-year-old boy presented with progressive drooping of both upper eyelids for 10 years. Past history of right sided hemi-plegia and left facial nerve palsy was present. Examination (OU) showed total external ophthalmoplegia, ptosis and pigmentary retinopathy. The patient also had a short stature (height 121.9 cm) for his age.
