Double fixation autograft technique for neglected patellar tendon rupture in a low resource setting: A 24 month follow up.

Introduction And Importance: Neglected patellar tendon rupture is a rare but disabling condition, often considered as a developing-country entity, due to late diagnosis or inadequate initial management. The therapeutic approach is complex, requiring surgical reconstruction. Several techniques have been described, including the use of autografts, allografts or synthetic materials.

Linear dielectric spectroscopy of a polymer network stabilizing a ferroelectric liquid crystal.

In this study, the linear dielectric characterization of a ferroelectric liquid crystal (FLC) stabilized by an anisotropic polymer network (PSFLC) was investigated. The liquid crystal employed in the PSFLC composites exhibited the chiral smectic C phase (SmC*), with a short helical pitch, a high tilt angle, and a high degree of spontaneous polarization. Dielectric spectroscopy was preceded by polarizing optical microscopy, as well as structural and electro-optical studies on pure FLC and PSFLC composites at different polymer concentrations.

Bennett Dislocation Fracture Combined With a Trapezium Fracture and Advantages of Iselin K-Wire Fixation: A Case Report.

The combination of a trapezium fracture and a Bennett fracture-dislocation is rare in hand trauma, posing both diagnostic and therapeutic challenges. Anatomical reduction and stabilization of the thumb metacarpophalangeal (MCP) joint, along with optimal management, are key to achieving a good outcome. We present the case of a 20-year-old motorcyclist with this lesion, treated with closed reduction using the Iselin K-wire fixation.

Mature Teratoma of Posterior Mediastinum in a Newborn: A Case Report.

Teratomas are germ cell tumors that can appear in different parts of the body, most often in the ovaries or testes. Treatment depends on whether the tumor is mature or immature: mature teratomas are usually removed surgically, while immature ones often require chemotherapy as well. Teratomas located in the mediastinum, particularly in the back part (posterior mediastinum), are rare.

Hydranencephaly in a Newborn: A Case Report and a Review of the Literature.

Hydranencephaly (HE) is a severe and isolated malformation affecting the cerebral mantle. In this condition, the cerebral hemispheres are entirely or almost entirely absent, replaced by a membranous sac filled with cerebrospinal fluid, while the midbrain is usually preserved. Although HE is a relatively rare brain disorder, the differential diagnosis must include conditions such as severe hydrocephalus, porencephalic cysts, and alobar holoprosencephaly.
