Subcutaneous Lipoma Mimicking Irreducible Inguinal Hernia

Inguinal or groin region is an area of diagnostic mysteries. It is usually associated with a painless or painful swellings. Swellings in this area can be congenital or acquired, acute or chronic, single or multiple, soft to hard, mobile to immobile and appear suddenly or gradually. Commonest swelling in this region is a  simple direct or indirect inguinal hernia in children and adults with a positive cough impulse. The next common lump is a femoral hernia, hydrocoele, sebaceous cyst or an enlarged reactive or malignant lymph node. Other uncommon Differential diagnosis includes ectopic testes, funiculitis, femoral artery aneurysm, pseudoaneurysm, hidradenitis, epididymitis, varicocele and abscess. Subcutaneous lipoma is a rare condition which can mimic a diagnosis of irreducible indirect inguinal hernia and other diagnostic problems for the attending physicians. We present a case of groin lipoma mimicking irreducible right sided indirect inguinal hernia in young healthy man

Graphene-Based Plasmonic Metamaterial Perfect Absorber for Biosensing Applications

Graphene as a mono-atomic sheet has recently grabbed attention as a material with enormous properties. It has also been examined for enhancing absorbance in the current plasmonic structure. This has led to an increment in the sensitivity of the plasmonic sensors. In this paper, we present theoretical investigation of the novel graphene-based plasmonic metamaterial perfect absorber for biosensing applications. The simulation study performs the analysis of the novel plasmonic metamaterial absorber structure by adding coatings of graphene sheets. Each sheet of graphene enhances absorbance of the structure. In this study, we demonstrate three layers of graphene sheets lead to perfect absorbance (100%) for multiple bands in the visible and near-infrared regions. Furthermore, we also computed the sensitivity of the graphene-based proposed structure by varying the refractive index (RI) of the sensing region from 1.33–1.36 with RI change of 0.01. Proposed fabrication steps for realization of the device are also discussed
