BACKGROUND Nail involvement is common in psoriasis patients and is often associated with severe disease. Patients with nail psoriasis experience pain, functional impairment and social stigma, with significant restriction of daily activities and quality of life. However, nail psoriasis often goes untreated, as many physicians believe it is difficult to treat, despite the availability of effectiv...

Tail biting trellis codes and block concatenated codes are discussed from random coding arguments. An error exponent and decoding complexity for tail biting random trellis codes are shown. Then we propose a block concatenated code constructed by a tail biting trellis inner code and derive an error exponent and decoding complexity for the proposed code. The results obtained by the proposed code ...

BACKGROUND Knee or tibiotalocalcaneal arthrodesis is a salvage procedure, often with unacceptable rates of nonunion. Basic science of fracture healing suggests that compression across a fusion site may decrease nonunion. A novel ratcheting arthrodesis nail designed to improve dynamic compression is mechanically tested in comparison to existing nails. METHODS A novel ratcheting nail was design...

Melanonychia, or melanin-derived brown-to-black nail pigmentation, is a diagnostic challenge for clinicians. The most serious disease of the nail unit, melanoma, primarily presents with melanonychia. However, melanonychia most often occurs as a result of benign etiologies such as nail matrix melanocytic activation, nail matrix melanocytic hyperplasia, and nail invasion by melanin-producing path...

Full article available online at Healio.com/Orthopedics. Search: 20140225-52 Chronic anterior knee pain is the most common complication after tibial nail insertion. Its etiology remains unknown, and multifactorial sources have been suggested. The authors believe that nail prominence and the insertion point of the nail are important in the development of anterior knee pain. The purpose of this r...

Central nervous system organization of masticatory muscles determines the magnitude of joint and muscle forces. Validated computer-assisted models of neuromuscular organization during biting were used to determine organization in individuals with and without temporomandibular disorders (TMD). Ninety-one individuals (47 women, 44 men) were assigned to one of four diagnostic groups based on the p...

This article presents new intramedullary (IM) nail design for femur diaphyseal fractures osteosynthesis. Biomechanical comparison of the two IM nails (standard locking and new developed) was conducted. Femur medullary canal architectonics was studied with the help of computer tomography (CT) data. Three-dimensional (3D) models of the femur, its transverse fracture, standard locking nail and new...

The study of host-parasite relationships involving vector-borne parasites requires understanding interactions between parasites and vectors. The capacity of haemosporidians to infect insects has clear evolutionary consequences for the transmission of diseases. Here, we investigated (i) the associations between blood parasites, biting midges and birds and (ii) the potential specificity between b...

Identification of biting lice species on the infected domestic chickens and their distribution on different body regions were studied at El-Beheira Governorate. Results showed two main species of biting lice on infected chickens; the chicken body lice, Menacanthus cornutus and the shaft lice, Menopon gallinae. Statistical analysis showed significance differences in the numbers of biting lice in...

Fingernail biting is a habit that is developed by numerous people, especially children and teenagers. Many clinicians believe that the habit of fingernail biting stems from nervousness or anxiety. Students, especially students with disabilities, can be easily distracted from instruction, can become the target of negative peer attention, and can get socially ostracized by habit problems such as ...
