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.

PILES


BRIEF IDEA ABOUT PILES (Hemorrhoids)

What is piles ?
 
Dilatation of radicles of rectal veins within the anal canal is called piles.The medical term for piles is hemorrhoids.Compared to arteries veins are weak due to thin walls and hence any backpressure in the veins can make them tortuous.There are three rectal veins namely superior, middle and inferior rectal veins.Any obstructions or increase of pressure in these veins can predispose piles.

Depending upon the situation there are two types of piles.

1) External piles.         2) Internal piles.

1) External piles:-

This type of piles is seen outside the anal opening and is covered by skin.It is black or brown in colour.This type of piles is very painful due to rich nerve supply in this area.

2) Internal piles:-

It is inside the anal canal and internal to the anal orifice.It is covered by mucous membrane and is red or purple in colour.These piles are painless.

Some times internal and external piles occure in same individual.

Factors responsible for piles:--

1) This is a familial disease.

2) Piles is seen only in animals maintain an erect posture. This is due to congestion in the rectal veins due to the effect of gravity.

3) It is common in individuals having chronic constipation.Those who have a habit of visiting the toilet due to frequent urge for stool may develop piles in future.

4) Piles is common in those who take excess of chicken, prawns, spicy food ect.Those who take vegetables and fibrous food are rarely affected.

5) Some ladies get piles during pregnancy due to compression of rectal veins by the uterus.

6) Cancerous lesions in the rectum can obstruct blood flow and result in piles.

Signs and symptoms of piles:--

1) Pain:-

Pain is common in external piles which will be worse while straining at stool.

2) Bleeding:-

Bleeding comes in splashes while pressing for stool.Bleeding may be profuse in some cases.

3) Protruding mass:-

In external piles the swelling can be felt around the anal orifice.In case of internal piles initially it can not be felt.When the disease progresses the piles protrude during stool and will go inside automatically.When the condition becomes worse the protruded piles will not go back in to the anus.

4) In some cases there will be discharge of mucus with itching around the anal orifice.

Complications of piles:--

1,Infection: The infection can spread to deep veins resulting in septicaemia.
2,Fibrosis: Here the piles become fibrosed with hardening of anal orifice.
3,Thrombosis: Here the blood inside the piles will form clots and can obstruct blood flow.
4,Gangrene: Here the tissues in the piles and nearby skin die due to lack of blood supply.
5,Suppuration: When the piles suppurate it can produce abscess with discharge of pus.

Treatment of piles:--

Initially it is treated on the basis of symptoms.Constipation should be treated.If there is anaemia iron should be give.Homoeopathic medicines can give good results. If medicinal treatment is not giving any result the following can be tried.

1) The thrombosed external pile is excised under local anaesthesia.

2) Sclerosant injection therapy can reduce the size of piles.

3) Rubber band ligation around the neck of piles is useful in some cases.

4) Cryosurgery is very effective.

5) Anal dilatation can reduce constipation and pain.

6) Haemorrhoidectomy is the surgical removal of piles.


How to prevent piles?

1) Eat plenty of fruits and vegetables.

2) Take fibrous food.

3) Avoid excess intake of meat,prawns,crabs ect.

4) Keep a regular timing for food.

6) Drink sufficient quantity of water.

7) Keep a regularity in bowel habits.

8) Take treatment for constipation.
