BONE DISEASE:OSTEOPOROSIS

Bone is a dynamic body tissue which get calcified and strength our body ,give exact shape ,posture which is impossible without it. Bones are living tissue which keep on remolding whole life (bone formation and destruction) in older age the process of destruction of bone(by osteoclast cells) is more the formation(by osteoblast cells) that's why in old age bone are weak and prone to fracture. Simply how much you stronger your bone in young age(before 30) that will delay destruction. Osteoporosis is define as reduced bone density, which causes a micro-architectural deterioration of bone tissue and lead to an increased risk of fractures. More the bone density stronger bone you have.  Most common associated with postmenopausal women. Other causes as follow.




CAUSES OF OSTEOPOROSIS 
DRUGS
Some of drugs work for body but with side effects (as every good thing have bad thing with it).
Corticosteroids is important cause of osteoporosis depend on duration and dose of therapy. Practically there is no safe dose of corticosteroids but if dose (prednison) exceed 7.5mg daily for 3 months the risks dramatically increase, key impact on osteoblast (bone forming cell) which is inhibited by this.Other agents are GnRH, sedative, anticonvulsion, alcohol excess, heparin.




ENDOCRINE DISEASES
There are multiple endocrine problem causes osteoporosis some of them are Hypogonadism, cushing's syndrome, hyperparathyroidism (destroy the bone and extract the calcium out of it) , hyperthyroidism.




INFLAMMATORY DISEASE
Inflammation is not good for health as well as our bone chronic inflammation lead to the destruction of bone and risk of osteoporosis is develop i-e Rheumatoid arthritis, ankylosing spondylitis.




 GASTROINTESTINAL DISEASE
Malabsorption the problem is with your absortion mechine so less amount of calcium absorped lead to osteoporosis, chronic liver disease.




MISCELLANEOUS
Some cancer and infection may cause osteoporosis but less in number. Myeloma,HIV infection....
CLINICAL FEATURE
You may not feel that your bone is weak until fracture occurs, asymptomatic until fracture occurs, back pain, often episode of minimal trauma may occurs.




DEXA SCAN
If you feel some kind of weakness go for dexa scane (dual energy X-ray absorptiometry) at lumber spine and hip. If T-score value is less then or equal to -2.5 you have it(osteoporosis).




LIFESTYLE MODIFICATION
Aim is to reduce the fracture. Cessation smoking right now, dietary calcium intake is helpful, regular bone stress exercises, Here moderate amount of alcohol intake is good, Vitamin D, protein diet, reducing harmful substance, minerals.




DRUGS
Consult to doctor for proper treatment normally bisphosphonates is the main stay.

DENGUE

D engue has emerged since in 1950s as worldwide problem by first recognition of dengue hemorrhagic fever during endemic in Thailand and Philippine. Dengue effect as many as 400 million people are infected each year, more then one-third of world's population living in dengue risk affected areas. An estimate tells 500,000 people with sever dengue require hospitalization  each year large proportion of whom are children  and 2.5% of effected dies. Real culprit is dengue virus carried by mosquitoes; which is leading cause of death in tropics and subtropics rarely occur in United states but endemic in Rico ,Puerto, Latin America, Southeast Asia and Pacific island.   SEROTYPES Four closely related to each other is DEN-1, DEN-2, DEN-3 ,DEN-4 .Recovery from each serotype provide lifelong immunity against that particular serotype. TRANSMISSION Aedes aegypti female mosquito is a primary vector for dengue. Lives in urban and breed in container made by humans it is a day...

ASTHMA

Advancing of industrialization improvement of status and life style gave birth to the disease which is not much fatal in past and prognosis is good but now due to disturbance of environment by variety of pathogen which are responsible for production of disease while inhaling  that air.The pathogen due to environmental factors influence upon then make them more resistance and stronger against us.Today open minded life people love to chose the sedentary life style and great value to appetite that is why obesity is common in developed countries; obesity is mother of diseases this will influence approx all the diseases asthma is one of them. Asthma affect 300 million people world-wide. Asthma is develop due to continuous inhalation of expose allergen(any substance induce our body immunity). Asthma is  under the heading of obstructive diseases  Extrinsic Asthma(this is due to expose allergen to body) Intrinsic asthma(family history of asthma) SIGN AND SYMPTOM First not...
