The prevalence of back pain during childhood is 50%; in 22% of these cases, a specific diagnosis can be found. Osteoid osteoma is a rare benign tumor that occursonly in 20% of cases and involves the spine. The aim of this report is to explain an atypical case of lumbar osteoid osteoma with significant neurologic deficit at a very young age. A five-year-old boy was presented with refractory pain...

Polycentric knees are frequently used in transfemoral prostheses because they provide added stability in stance phase and relative ankle dorsiflexion in swing phase. Despite this relative ankle dorsiflexion, patients still complain of inadequate toe clearance even with polycentric knees. We hypothesize that active ankle dorsiflexion via a knee-ankle coupling provides more toe clearance than pro...

Evaluation of residual stress in the weld toe region is of critical importance. In this paper, the residual stress distribution both near the surface and in depth around the weld toe was investigated using neutron diffraction, complemented with X-ray diffraction. Measurements were done on a 1300 MPa yield strength steel welded using a Low Transformation Temperature (LTT) consumable. Near surfac...

Thirty-four patients wtih fibrodysplasia (syn., myositis) ossificans progressiva are described. Marked delay in diagnosis was usual, but all had characteristic skeletal malformations and ectopic ossification. The clinical features included: four types of malformation of the big toe, reduction defects of all digits, deafness, baldness of the scalp, and mental retardation. Progression of disabili...

To evaluate whether the clinical pattern of gout differed between elderly women and men a retrospective study was performed in all women (22) and men (18) in our rheumatological clinics who developed gout after the age of 60. The diagnosis was made after a mean of 2.6 years of joint complaints in women and after 1.2 years in men. In about half the patients complaints started in more than one jo...

First cousins, related through their mothers, showed a pattern of craniofacial, brain, and limb anomalies consistent with the acrocallosal syndrome. Both patients had a defect of the corpus callosum, macrocephaly with a protruding forehead and occiput, hypertelorism, non-horizontal palpebral fissures, a small nose, notched ear lobes, and postaxial polydactyly of the hands. The boy, in addition,...

A Hindu male, aged 17 years, came to us for an investigation regarding his albuminuria. Past history.?Four years ago the patient had an acute attack of pain with redness and inflammation of the metatarso-phalangeal articulation of the big toe of the left foot; this was diagnosed as gout. He had two more similar attacks which affected the metatarso-phalangeal articulations of both the feet. Duri...

Despite a clear somatotopic organization of the motor cortex, a movement can be learned with one extremity and performed with another. This suggests that there exists a limb-independent coding for movements. To dissociate brain regions coding for movement parameters from those relevant to the chosen effector, subjects wrote their signature with their dominant index finger and ipsilateral big to...

MATERIALS AND METHODS: Between 2014 and 2016, thenar fascial flaps and nail bed grafts were used in five patients. All the patients had full-thickness nail bed defects due to machines or door jamming incidents, and the sizes of the defects were more than half of the whole nail bed. We designed the flaps as general thenar flaps, performed suprafascial dissection, and elevated the dermal flaps pr...

an experiment was conducted using 640 day-old sexed commercial broiler chicks (ross 308 strain) from 10 to 49 days of age. the experimental design was a completely randomized factorial one. the experimental units (pens) contained 20 chicks each and were allotted at random to 4 dietary treatments × two sexes with 4 replicates per treatment. four dietary treatments were formulated based on corn a...
