Background: Arthrogryposis Multiplex congenita is a
rare disorder, characterized by multiple joint deformities
i.e. multiple congenital contractures, with shapelessly
cylindrical limbs and absent skin creases.
Club foot can be the only obvious deformity of this
widespread disorder.
Objective: To assess the most frequent recurrent
deformity after extensive soft-tissue release operations for
arthrogrypotic club foot and its appropriate treatment
regarding combined tendon transfer and bony operations.
Methods: A retrospective study of 14 patients with
arthrogrypotic club foot (28 feet), had been operated on by
multiple soft tissue and bony operations and followed in a
period between January (1993) till February (1999).
Both clinical assessment including goniometer use to
measure the recurrent deformity, and radiological
assessment, was used in this study.
Results: In this series, 4 patients (7 feet) had recurrent
deformity, 3 patients
(5 feet) out of these 4 had recurrent forefoot adduction, 2
of them had bilateral affection. The 4th patient had
bilateral recurrent varus heel.
Conclusion: The main problem in arthrogrypotic club
foot is the liability for recurrence. The most frequent
recurrent deformity was forefoot adduction. Combined
tendon transfer and bony operations can correct the
deformity once performed at the same cession forefoot
adduction. All required 2nd operation, in the 1st 3 patient
combined Evan’s (calcaneocuboid wedge-excision) and
tibialis anterior transfer operations were performed.
Talectomy was performed on one foot in the 4th patient,
combined with capsulectomy of the calcaneocuboid joint,
while triple arthrodesis don on the other foot
Nuclear medicine is important for both diagnosis and treatment. The most common treatment for diseases is radiation therapy used against cancer. The radiation intensity of the treatment is often less than its ability to cause damage, so radiation must be carefully controlled. The interactions of alpha particle with matter were studied and the stopping powers of alpha particle with ovary tissue were calculated using Beth-Bloch equation, Zeigler’s formula and SRIM Software also the range and Liner Energy Transfer (LET) and ovary thickness as well as dose and dose equivalent for this particle were calculated by using Matlab language for (0.01-200) MeV alpha energy.
Thermal performance of closed wet cooling tower has been investigated experimentally and theoretically
in this work. The theoretical model based on heat and mass transfer equations and heat and mass transfer balance equations which are established for steady state case. A new small indirect cooling tower was used for conducting experiments. The cooling capacity of cooling tower is 1 kW for an inlet water temperature of 38oC, a water mass velocity 2.3 kg/m2.s and an air wet bulb temperature of 26oC. This study investigates the relationship between saturation efficiency, cooling capacity and coefficient of performance of closed wet cooling tower versus different operating parameters such wet-bulb temperature, variable air-spray water fl
This research aims to examine the relationship between learning organization and behavior of work teams. The variable of the learning organization took four dimensions depending on the study (sudhartna & Li, 2004): Common cultural values , communication, knowledge transfer and the characteristics of workers. The behavior of teams was identified on the basis of realizing of the respondents of their organization to work as a team where the research relied concepts applied in the study (Hakim , 2005) , and chose to research the case of a service organization for the study and relied on four dimensions of coordination , cooperation , sharing of information , the performance of the team, and was a curriculum approach and des
