facial reconstruction is one of the most challenging problems faced by a reconstructive surgeon. we present a case of complex facial reconstruction with a composite trauma to the nose resulting in near total loss of skin and lining along with complete loss of left eyebrow with exposed frontal bone and partial loss of the left eyelid. we combined a temporoparietal fascial flap for reconstruction...
Background and Aims: There is not sufficient knowledge about the relationship between smoking and vertical bone loss in periodontal diseases. There are also important evidences which propose harmful effects of smoking on periodontal tissues including alveolar bone. The purpose of this study was to assess the relationship between smoking and prevalence and severity of vertical bone defects.Mater...
Objectives The first cause of tooth loss in developed countries is periodontitis. Chronic periodontitis is the most common form of periodontitis and it is characterized by loss of periodontal attachment, destruction of alveolar bone and eventual loss of teeth. Atorvastatin is a statin drug used for the treatment of high cholesterol. Statins can stop the inflammatory proc...
bone mass loss is one of the commonest menopause symptoms, resulting from cessation of estrogen production. compounds which have estrogen – like biological activity similar to “isoflavones” present in plants especially soy, may reduce bone loss in postmenopausal women, because as they are similar in structure to estrogens. this study, therefore, was undertaken to assess the effect of soy protei...
Background: The trabecular bone changes in the tibia of C3H/HeN mice were measured 12 weeks after whole body irradiation with various doses of fast neutrons (0-2.4 Gy) or 137Cs-generated gamma-rays (0-6 Gy). Materials and Methods: Serum calcium, phosphorus, estradiol concentration and alkaline phosphatase activity were measured. Tibiae were anal...
conclusions in contrast to the findings in humans and certain other species, glucocorticoid administration caused anabolic effect on the cortical bone of tibia diaphysis bone in rats. results glucocorticoid-treated rats showed weight loss and considerable mortality (21%). the biomechanical properties (maximum force) of glucocorticoid-treated rats in groups 4 (62 ± 2.9), 6 (63 ± 5.1), and 7 (60 ...
Abstract Background: The aim of this study was to examine the effect of isometric training on prevention of bone density reduction of limbs during an immobilization period. Methods: In this quasi-experimental study, 60 men with fractures of the femoral bone, needing at least one month immobilization period, were selected and randomly assigned in control and experimental groups, the latter u...
Introduction: Osteoporosis is a disease in skeletal system that is recognized by a lack of bone density and degeneration of bone tissue and can lead to increase the risk of bone fracture or even death. So, this study was conducted to determine the prevalence of decreased bone density in people with common risk factors referred to Al-Zahra Educational-Medical Center in Isfahan City years 2018-20...
Bone loss after spinal cord injury leads to increased fragility of bone and subsequent risk for low-trauma fractures in the sublesional parts of the body. Although in such injuries upper limbs are normally innervated, bone loss may occur in the upper extremities. The present study was designed to determine the systemic effects of spinal cord injury on the fracture healing of upper limbs in rabb...
