INTRODUCTION: Preterm infants are commonly treated by non-invasive ventilation (NIV) and nasal continuous positive airway pressure (CPAP), which are associated with fewer complications than nasotracheal intubation. In preterm infants with a cleft lip and palate, this method of respiratory management is difficult or impossible to perform because of air leakage through the cleft defect. CASE: We report a male infant who was born at 29 weeks of gestation with a left complete unilateral cleft lip and palate...

Terminal hip flexion contributes to increased strain in peripheral nerves at the level of the hip joint. The effects of hip abduction and femoral version on sciatic nerve biomechanics are not well understood. A decrease in sciatic nerve strain will be observed during terminal hip flexion and hip abduction, independent of femoral version. Six un-embalmed human cadavers were utilized. Three Differential Variable Reluctance Transducers (DVRTs) sensors were placed on the sciatic nerve while the leg was flexed to 70° with a combination of - 10°, 0°, 20° and 40° adduction/abduction...

The article gives our own experience in the determination and study of additional laboratory criteria (total lipids, cholesterol, maximum and area chemiluminescence, antioxidant activity) at the local level (in bile) in patients with bile duct obstruction of malignant etiology. Constellation of metabolic disorders allowed to propose an original method for determining the lithogenicity of bile (integral indicator of lithogenicity). The obtained data made it possible to justify the need to assess the degree of metabolic disturbances in bile, on the basis of which it is possible to predict the risk of lithogenesis and the duration of stent operation, which in turn helped optimize the algorithm for choosing the method of bile ducts decompression aimed at preventing early obturation of endoprostheses...

This narrative review article aims to examine current evidence of knee innervation in order to develop a technique of targeting pure sensory innervation of the knee joint without compromising motor function. A literature review of knee innervation was performed to gain an anatomic understanding of terminal sensory branches of the relevant target nerves (femoral, obturator, sciatic, and lateral femoral cutaneous). Pure sensory block of the knee joint is challenging due to important contributions from the muscular innervation close to the joint and the variability of nerves afferents contained within and around the adductor canal...

BACKGROUND: Oronasal/antral communication, loss of teeth and/or tooth-supporting bone, and facial contour deformity may occur as a consequence of maxillectomy for cancer. As a result, speaking, chewing, swallowing, and appearance are variably affected. The restoration is focused on rebuilding the oronasal wall, using either flaps (local or free) for primary closure, either prosthetic obturator. Postoperative radiotherapy surely postpones every dental procedure aimed to set fixed devices, often makes it difficult and risky, even unfeasible...
