Health and Medical Care Tips
A laser is a device that emits light (electromagnetic radiation) through a process called stimulated emission. The term laser is an acronym for light amplification by stimulated emission of radiation.
Lasers techniques use a high intensity light to destroy or cut through the tissues.
There are a variety of lasers used in destruction of skin lesions [Read more...]
Distention of abdomen can be due to an underlying disease or due to accumulation of fat. Normal abdomen distention needs to be differentiated from that due to disease.
Generalized distension occurs in ascites, obesity and patients with excessive flatus. Localized distension occurs with individual visceromegaly and with neoplasms.
Here are the differentiating points. [Read more...]
Cryosurgery or cryotherapy is the application of extreme cold to destroy abnormal or diseased tissue. The term comes from the Greek words cryo which means icy coldand surgery meaning hand work.
Cryosurgery is used to treat a number of diseases and disorders, especially a variety of benign and malignant skin conditions. Skin lesions such as warts, molluscum contagiosum, cutaneous tags, seborrhoeic keratosis, adenoma sebaceum, epidermal and vascular nevi etc. can also be destroyed by freezing.
The commonly used for this purpose are
For smaller lesions carbon dioxide snow is to be compressed in the form of a thin pencil which should be pressed on the lesion. For larger lesions, carbon dioxide snow can be mixed with acetone to form carbon dioxide slush which is painted on the lesion with a brush. [Read more...]
In a patient with an abdominal disorder, the following points must be asked whilst taking the history and noted on examination.
History
History is of paramount importance in clinical examination. It enables you to narrow your examination to a region and also guides you about the likelihood of particular disorder. Following points should be asked in patient of abdominal complaints. These points cover whole abdomen in general and can be individualized depending upon the complaint. [Read more...]
This disease was previously called non-bullous variety of ichthyosiform erythroderma. It is inherited as an autosomal recessive way. Thus consanguine marriages as between close relative, are more likely to result in manifestation of the disease even though other members of the family may be normal. (see Figure)
Usually the affected child shows a diffuse erythema and scaling which is more prominent in the flexural aspects of the joints such as the cubital and the popliteal fossae.
The skin looks shiny and shows fine wrinkles when pressed between the thumb and the index finger. The disease does not show any relationship with the seasons, but becomes less prominent as the age advances.
Treatment
Hyperkeratosis of the palms and soles is called keratoderma. It may occur in association with ichthyosiform dermatoses, or there may be no other associated abnormality.
The hyperkeratosis may involve the entire surface of the palms and soles when it is called diffuse keratoderma or it may occur only in small punctuate areas when it is called punctuate keratoderma.
Sometimes it occurs only in localized areas when it is called localized keratoderma. Diffuse palmo-plantar keratoderma is inherited in two ways.
The autosomal dominant type, also called tylosis remains limited to the palmar and plantar aspects of hands and feet and maybe associated with fissures, while the autosomal recessive type, called Mal de Meleda, tends to extend onto the dorsal aspects of the hands and feet and is usually associated with a variable degree of erythema.
There are several other diseases and syndromes which may be associated with palmo-plantar keratoderma.
Treatment
The treatment in all these cases consists of removing the thick masses of hyperkeratosis and keeping the skin soft and supple. Sodium bicarbonate soaks followed by local applications of keratolytic agents such as five to tern percent salicylic acid in petrolatum or 40 percent urea in glycerine may help.
Bandage of the palms and soles during the night after a liberal application of the keratolytic agent may provide additional help in softening the keratotic masses. In very severe cases, occlusive dressings with polyethylene sheets over keratolytic agents can be sued.
After the initial improvement, applications of keratolytic agents will have to be continued to prevent accumulation of the thick keratotic layers again.
There could be endless ways to get injured but mainly the trauma can be divided into five main categories depending on mechanism of injury.
Critics say wider use of memory stimulants may lead to addiction
Healthy people should have the right to boost their brains with pills, like those prescribed for hyperactive kids or memory-impaired older folks, several scientists contend in a provocative commentary.
College students are already illegally taking prescription stimulants like Ritalin to help them study, and demand for such drugs is likely to grow elsewhere, they say. “We should welcome new methods of improving our brain function,” and doing it with pills is no more morally objectionable than eating right or getting a good night’s sleep, these experts wrote in an opinion piece published online Sunday by the journal Nature.

This is the only method available so far, for permanent removal of supernumerary hairs. A variety of apparatuses are available for this purpose and some of these are combined with the apparatus used for other electro-surgical procedures.
The main purpose of electrolysis is to destroy the hair bulb and its dermal papilla. This can be achieved by means of an apparatus which uses direct current (DC) and causes ionization and accumulation of sodium ions at the negative pole i.e. the needle electrode.
Sodium ions react with water and produce sodium hydroxide which destroys the tissue. This procedure is painless and the hydrogen gas liberated simultaneously can be seen bubbling through the hair follicle.
The process is slow and it may take 30-60 seconds for each hair. In the other method, electro-coagulation or electro-desiccation may be used to produce heat and destruction of the hair bulb. One may use a high current for a short period or a low current for a longer period. [Read more...]
Open fracture of leg bone with baring of tibia
Injury is a global public health problem and the dominant cause of death and disability of the young and active people, particularly
in industrialized countries. Injury is the seventh cause of death worldwide , and the number one cause of death in the young. This data belongs to US as records from our country are not available.
Injury is an unwanted side effect of industrialization. We all are so used to vehicles. Automobiles form an integral part of our surrounding. Automobile accidents are leading cause of death and disability in industrialized countries. It is projected that road traffic fatalities will rise to the third leading global cause of death by the year 2020.
The problem is very big. Much larger than I or you can fathom.
