The theme for this year's world health day is depression, with a slogan- Depression: Let's Talk. Depression is aptly chosen as this year's theme because it is taking pandemic proportions in today's competitive world. More and more young generations are diagnosed as having depressions every day attributing to failures in relationships, academics, careers, finances and many other seemingly inconsequential reasons. As per the WHO's definition of health, health is a state of complete physical, mental and social well-being but not merely the absence of disease or infirmity. Yes, a person may seem well from others' perspective but he may be having troublesome issues within himself. He may not feel healthy mentally. Some unknown fear, apathy, anxiety may be lurking in his psyche and he may not know to whom he should consult. It is a global necessity that every one of us understands the fact that nobody is immune to mental illness and we should not attach a stigma t...

B.P. Koirala Institute of Health Sciences (BPKIHS) is a tertiary health care center and referral center in eastern development region. Thousands of patients come here every day seeking outpatient medical care. It also has got a 700-bedded inpatient ward and the largest (in terms of manpower) emergency unit in the nation.

Q. Discuss the types of calcification. The mineralisation of body tissues with calcium is a normal physiological process in tissues like bones and teeth, termed as physiological calcification. However, sometimes the visceral tissues and other soft tissues may also get calcified in many diseased states, which is called pathological calcification. In addition to the calcium salts, smaller amounts of iron, magnesium and other minerals may also be deposited. Pathological calcification can be broadly classified into two types: Dystrophic Calcification and Metastatic Calcification. Dystrophic calcification: When the deposition takes place in dead or dying tissues, then it is termed as dystrophic calcification. The serum calcium levels are normal and the calcium metabolism is not deranged. Though hypercalcemia is not a prerequisite for dystrophic calcification, hypercalcemia can exacerbate it. It is seen in areas of tissue necrosis of any type. It is almost always present in the ather...
