EFFECT OF ALCOHOL ON THE MEMBRANES.
The parts which first suffer from alcohol are those expansions of the body which the anatomists call the membranes. "The skin is a membranous envelope. Through the whole of the alimentary surface, from the lips downward, and through the bronchial passages to their minutest ramifications, extends the mucous membrane. The lungs, the heart, the liver, the kidneys are folded in delicate membranes, which can be stripped easily from these parts. If you take a portion of bone, you will find it easy to strip off from it a membranous sheath or covering; if you examine a joint, you will find both the head and the socket lined with membranes. The whole of the intestines are enveloped in a fine membrane called peritoneum . All the muscles are enveloped in membranes, and the fasciculi, or bundles and fibres of muscles, have their membranous sheathing. The brain and spinal cord are enveloped in three membranes; one nearest to themselves, a pure vascular structure, a network of blood-vessels; another, a thin serous structure; a third, a strong fibrous structure. The eyeball is a structure of colloidal humors and membranes, and of nothing else. To complete the description, the minute structures of the vital organs are enrolled in membranous matter."
These membranes are the filters of the body. "In their absence there could be no building of structure, no solidification of tissue, nor organic mechanism. Passive themselves, they, nevertheless, separate all structures into their respective positions and adaptations."
Membranous deteriorations.
-------------------------
In order to make perfectly clear to your mind the action and use of these membranous expansions, and the way in which alcohol deteriorates them, and obstructs their work, we quote again from Dr. Richardson:
"The animal receives from the vegetable world and from the earth the food and drink it requires for its sustenance and motion. It receives colloidal food for its muscles: combustible food for its motion; water for the solution of its various parts; salt for constructive and other physical purposes. These have all to be arranged in the body; and they are arranged by means of the membranous envelopes. Through these membranes nothing can pass that is not, for the time, in a state of aqueous solution, like water or soluble salts. Water passes freely through them, salts pass freely through them, but the constructive matter of the active parts that is colloidal does not pass; it is retained in them until it is chemically decomposed into the soluble type of matter. When we take for our food a portion of animal flesh, it is first resolved, in digestion, into a soluble fluid before it can be absorbed; in the blood it is resolved into the fluid colloidal condition; in the solids it is laid down within the membranes into new structure, and when it has played its part, it is digested again, if I may so say, into a crystalloidal soluble substance, ready to be carried away and replaced by addition of new matter, then it is dialysed or passed through, the membranes into the blood, and is disposed of in the excretions.
"See, then, what an all-important part these membranous structures play in the animal life. Upon their integrity all the silent work of the building up of the body depends. If these membranes are rendered too porous, and let out the colloidal fluids of the blood the albumen, for example the body so circumstanced, dies; dies as if it were slowly bled to death. If, on the contrary, they become condensed or thickened, or loaded with foreign material, then they fail to allow the natural fluids to pass through them. They fail to dialyse, and the result is, either an accumulation of the fluid in a closed cavity, or contraction of the substance inclosed within the membrane, or dryness of membrane in surfaces that ought to be freely lubricated and kept apart. In old age we see the effects of modification of membrane naturally induced; we see the fixed joint, the shrunken and feeble muscle, the dimmed eye, the deaf ear, the enfeebled nervous function.
"It may possibly seem, at first sight, that I am leading immediately away from the subject of the secondary action of alcohol. It is not so. I am leading directly to it. Upon all these membranous structures alcohol exerts a direct perversion of action. It produces in them a thickening, a shrinking and an inactivity that reduces their functional power. That they may work rapidly and equally, they require to be at all times charged with water to saturation. If, into contact with them, any agent is brought that deprives them of water, then is their work interfered with; they cease to separate the saline constituents properly; and, if the evil that is thus started, be allowed to continue, they contract upon their contained matter in whatever organ it may be situated, and condense it.
"In brief, under the prolonged influence of alcohol those changes which take place from it in the blood corpuscles, extend to the other organic parts, involving them in structural deteriorations, which are always dangerous, and are often ultimately fatal."
FOOD POISONING
Introduction:
Food poisoning is an acute gastroenteritis caused by the consumption of a food material or a drink which contains the pathogenic micro organism or their toxins or poisonous chemicals.Food poisoning is common in hostels,hotels,communal feedings, and festivel seasons.
A group of persons will be affected with same type of symptoms ,and they give a history of consumption of a common food before few hours.
Types of food poisoning
1) Bacterial food poisoning:
Here the micro organisms called bacteria are responsible.The food material may contain the pathogenic bacteriae or their toxin and will be ingested along with the food.
2) Non bacterial food poisoning:
Due to the presence of toxic chemicals like fertilizers,insectisides,heavy metals and ect.
Since bacterial food poisoning is common it is discussed here.
Bacterial food poisoning:
All bacteria are not harmful.There are some pathogenic bacteria which secrete toxins and cause clinical manifestations.These organisms enter the human body through food articles or drinks.
How food poisoning occures:
1) Presence of bacteria in the water.
2) The raw materials for the food may contain toxins.
3) Premises where the food is prepared may contain micro organisms or toxins.
4) Food handlers may have some infectious diseases.
5) Some animals like dogs,rats may contaminate the food.
6) If prepared food is kept in the room temperature for a long time and heated again can make a chance for food poisoning.
7) Purposely some body mixing toxins in the food.
Some common bacterial food poisonings.
1) Salmonella food poisoning:
There are three different varieties of salmonella bacteria.(salmonella typhimurium,salmonella cholera suis,salmonella enteritidis) These bacteria are present in milk, milk products and eggs. Symptoms of this food poisoning include nausea, vomiting and diarrhoea. Fever is also common.
2) Botulism:
This is the dangerous type of food poisoning caused by clostridium botulinum. The spores of these organisms are seen in the soil and enters the human body through pickles and canned fish ect.Compared to other food poisonings here vomiting and diarrhoea are rare Mainly the nervous system is affected.The symptoms starts with double vision,numbness with weakness.Later there will be paralysis with cardiac and respiratory failure ending in death.
3) Staphylococcal food poisoning:
It is caused by staphylo coccus aureus. These organisms usually cause skin troubles like boils and eruptions.It causes mastitis in cow.Through the milk and milk products it enders and causes gastroenteritis.There will be vomiting,abdominal cramps with diarrhoea.
4) Closteridium food poisoning:
This is caused by closteridium perfringens.They are present in stool,soil and water. They enter the body through,meat,meat dishes and egg ect.If food articles are cooked and kept in room temperature for a long time and heated again before eating can result this food poisoning.Symptoms include vomiting ,diarrhoea and abdominal cramps.
5) Bacillus cereus:
The spores of these organisms can survive cooking and causes enteritis. Diarrhoea and vomiting is common in this infection.
How to investigate food poisoning?
1) Examine each and every person affected.
2) Water sample should be tested.
3) Kitchen, store room and food samples should be examined.
4) The cook and food handlers should be questioned and examined.
5) Samples of vomitus and stool of all victims should be tested to identify the bacteria.
How to prevent food poisoning:-
1) Only purified water should be used.
2) Hygiene should be maintained by all persons keeping contact with food.
3) Workers should use masks, cap and gloves during cooking and serving.
4) Sick individuals should not come in contact with food materials.
5) Kitchen and premises should be neat and clean.
5) Vessels should be washed with soap and hot water.
6) Should not keep the prepared food for a long time in room temperature.
7) All food materials should be kept in closed containers.
8) Animals like dog, cat, rat ect should not come in contact with food materials.
9) Vegetables should be washed before cooking.
10) Meat should be fresh and should be purchased from recognised slaughter house.
HERNIA
Introduction
Hernia is an abnormal protrusion of internal organs through an abnormal opening in the wall of the cavity.A combination of increased pressure inside the body with weakness in the wall is responsible for this condition.In this condition internal organs or parts of organs are protruded out forming a swelling which will increase the size with coughing and lifting weight,and while passing stool and urine.In lying down position the swelling goes inside except in strangulated and irreducible hernia.
Causes:-
1, Weakness in the body wall:--
a) Congenital weakness.
b) Acquired weakness due to injuries,wasting of muscles,suppurative lesions in the wall and presence of weak natural openings,obesity,lack of exercise,repeated pregnancy.
c) Surgical operation with improper suturing or sepsis of operated site.
2) Increased pressure inside the body.
a) Chronic constipation.
b) Recurrent cough.
c) Weight lifting.
d) Stricture of urethra.
Common sites for hernia:--
Hernia can occure anywhere in the body.However there are some common sites for hernia.Due to the presence of hard bony covering chest wall is normally not affected.Hernia in the lower back is also rare due to spine and back muscles and tough ligaments and sheeths.The common site for hernia is abdominal wall.Compared to other parts the abdominal wall is weak due to the presence of some natural orifices.There are some areas wherein the abdominal muscles are weaker and thin and all these factors make a chance for herniation.The common sites for hernia are following.
a) Inguinal hernia:
Here the abdominal contents protrude through the inguinal canal (passage in the lower abdominal wall just above the inguinal ligament.It is seen on either side).This type is common in males.Initially the swelling comes only while straining and goes back while lying down. Later the large portion of intestine may come out which may not go back easily.
b) Femoral hernia:
This type of hernia is more in females.Here the abdominal contents pass through the femoral canal which is seen just below the junction between the thigh and lower abdominal wall(Inside the femoral triangle).The contents pass downwards and comes out through saphenous opening in the thigh and forms a swelling under the skin.
c) Umbilical hernia:
This is common in children.The umbilicus is the weaker part of the abdomen.The contents of the abdomen may protrude as a bulb like swelling while crying and defecating.
d) Incisional hernia:
These hernias are seen in operated sites. Due to improper suturing or sepsis the operated site becomes weak resulting in hernia.
e) Epigastric hernia:
Here the hearniation occures in the epigastrium. It is a rare type.
f) Lumbar hernia:
Here the hernia appear in the lumbar area on either side of the lumbar spine(in the lumbar triangle).This is also a rare type.
g) Obturator hernia:
This is a rare type of hernia. Here the contents pass through obturator foramen in the pelvic bone.
Complications of hernia:--
1) Strangulation:
If the hernial orifice is narrow the abdominal contents may not go back easily, and later the blood flow to the herniated tissues may be blocked due to constricition.This can cause death of protruded intestine.
2) Intestinal obstruction:
This occures when the whole portion of the intestine is protruded in to the hernial sac. The narrow hernial orifice will block the passage of bowels.
3) Infection and peritonitis:
If there is strangulation with death of a portion of intestine there will be spread of infection to the abdomen resulting in peritonitis.
Treatment of hernia:--
Initial treatment: In the initial stages of hernia the following steps may be useful
1) Use of hernia belt:
Special types of hernia belts are available for each type of heania.This will prevent the protrusion and will reduce pain.
2) Constipation,recurrent cough,urinary obstruction ect should be treated.
3) Fat reduction will increase the strength of abdominal wall.
4) Abdominal exercises to increase the muscle tone.
5) Take plenty of leafy vegetables, fruits and fibrous diet for easy bowel movements.
6) Try other systems like Homoeopathy,Herbal medicine and ect
If no relief by the above steps consult a general surgeon for surgical management.
Surgical treatment.
The following operations are done depending up on the type and nature of hernia.
1) Hertniotomy : In this operation the contents of hernial sac is pushed in to the abdomen and neck of the sac is ligated with transfixion ligature and the sac is cut off.
2) Herniorrhaphy: Here along with herniotomy the posterior wall is repaired.
3) Hernioplasty: This operation is done if herniotomy is not possible due to wide neck of the sac.Here the repair is done with the healp of non absorbable materials like tantalum gauze,polypropylene mesh or stainless steel mesh.
