High leucocytosis interferes with colorimetric measurement of Haemoglobin
Hemoglobin estimation of a solution or a blood sample is commonly done in most cases by cyanmethhemoglobin method. But a less familiar method, which is also a photoelectric colorimetric methed,1developed by us, is followed in some areas of Bangladesh. The later method is a acid-hematin method and has found to have similar accuracy and stability. Unlike cyanmethhemoglobin method, it is very cheap and has a advantage that no biohazardous chemical have been used here2. Interestingly, during the development of the new method with a comparison to cyanmethhemoglobin method, it is observed that in both methods prepared fluid mixed with blood of high WBC count showed optical density resulting hemoglobin level that didn’t correspond with clinical condition of the patient. That means higher hemoglobin level was observed in a clinically anemic patient whose WBC count is very high e.g. in case leukemia. Moreover the blood mixed fluid, which is clear in other cases, was found to be hazy in these cases. To get rid from the problem we centrifuge the fluid and the clear supernatant fluid was used to measure the optical density and then the actual level of hemoglobin could be estimated which corresponded well with clinical condition of the patient. The deposit, after centrifugation, was examined under microscope and found plenty intact WBC. In normal cases, the deposits also shown WBC but were in very small number. Roughly it was estimated that hemoglobin level was increased by 1.2 to 1.4 gram% for 105WBC/cumm of blood. So, during estimation of hemoglobin in patient with very high WBC count (e.g leukemia) optical density should be taken from the supernatant fluid after centrifugation for few minutes (more than 3 minutes is satisfactory) of the prepared fluid.
Cyanmethaemoglobin method is followed in many countries for the last few decades, though potassium cyanide, which is used in this method, carries potential health hazard. Besides this, the limitation regarding high WBC count should be always considered. It can be easily proved in any laboratory by estimating hemoglobin of a patient having very high WBC count e.g. leukemia, by measuring absorbance before and after centrifuging the measuring fluid.

Why malarial parasite usually not found in peripheral blood
It is a common problem that malarial parasite is usually not found in peripheral blood in most suspected cases of malaria. The causes of this failure are many. It is important that there are many causes of febrile illnesses coming with shivering and going off with sweating like in malaria.
Among these:
1) Misdiagnosis: It is documented-
a.Tuberculosis, particularly extra pulmonary cases may be confused with malaria because of its single rise of temperature at the evening time. Particularly in younger patients the bout of fever may be so heightened that it starts with shivering and goes with sweating. In tuberculosis history is longer, weight loss and anorexia almost present in all cases but headache is rare which is common in malaria.
b. UTI (urinary tract infection)- fever in UTI case usually appears with shivering and goes with sweating but it occurs in multiple times in a day. There should be no symptoms of burning or frequency micturition when it affects the upper part of urinary tract. In this case (upper UTI) lower abdominal or back pain is common. Simple routine urine examination excludes the diagnosis.
c. Viral infection:- Viral infection is the commonest cause of febrile illnesses. Its onset is usually acute, seasonal and similar history of other members or neighbours. Most people in our country uses few doses of paracetamol before seeking advice from physician. Physician finds history of shivering and sweating in these cases but it is due to effect of paracetamol. When the action of paracetamol goes off fever comes again with shivering and when it acts fever goes with sweating.
d. Meningitis : It is a case of medical emergency. High rise of fever with headache is must so can be confused with malaria.
2. Use of some anibiotics can also prevent appearence MP in peripheral blood- like fluoroquinolones (e.g, ciprofloxacin), cotrimoxazole, tetracycline etc.
3. Collection of blood: After excluding the above causes of fever if diagnosis goes in favour of malaria, still malarial parasite may not be found in peripheral blood due to
a. Blood examined at early stage of malarial infection - Particularly in first week of illness number of infected RBC may be so low that MP can not be seen even after searching for longer period.
b. Time of collection- This is very critical that when blood should be collected for MP. Many physicians advice to collect blood at the height of temperature. But this is a wrong idea. Fever in malaria synchronizes with rupture of infected RBC releasing hemozoin, a febrile toxin. So at the height of temperature there should not be any intact infected RBC containing MP for demonstration in peripheral blood unless double cycles or multiple cycles on malarial infection are running which also not very rare. So, blood should be collected 1 to 2 hours or more before the onset of fever. When a fever goes off blood should to be collected at least 10 hours after an attack of fever because, this time is needed to develop a ring form of malarial parasite inside red cells.

Resurgent of Vector borne Diseases- In context to Bangladesh :Some Suggestions
In context to Bangladesh, India can be major source of those new types of diseases like dengue. In India, dengue has been epidemic for several years. Although dengue fever was documented in Bangladesh from the mid-1960s to the mid-1990s, but an outbreak of dengue haemorrhagic fever has not been previously reported.But in 2000, through mid November 5,575 hospitalized dengue cases were reported to the Ministry of Health in Bangladesh, with a case-fatality rate of 1.61 %.
Ades mosquito, the vector of this disease, can not fly more than 100 meters from its residence. So, there is no way to move this vector from air port to populating area of Dhaka, where dengue outbreak started first in Bangladesh. Moreover, the air way communications from Bangladesh to India have been established many years before liberation but there was no dengue outbreak during this period. So, there is very little chance of transmitting the disease by this route. Moreover, under the WHO International Health Regulation (IHR), all international airports and seaports are kept free from all types of mosquitoes for a distance of 400 meters around the perimeter of the ports.8 But it is possible that, the infected mosquito can travel via bus or train under their seats, in between luggage and transmit the disease to other populating area nearby the stoppage. The time of emergence of dengue outbreak in Bangladesh that occurred first in Dhaka coincides with period after the introduction of bus communication between Dhaka and Kolkata. So it will be logical to claim that the infected vectors can easily migrate to Dhaka via bus from India. Now, the recent introduction of railway communication can exacerbate the condition or import of new diseases agents like Japanese B encephalitis, chikangunya which are known to prevalent in many areas of India. So, it should be an urgent matter to prevent such migration of vectors through vehicles like bus or train.
The measures those can be taken to limit vectors migration could be as follows:
1) Before starting, the train or bus should make free from any vectors by using effective insecticides before the passengers take their seats.
2) The international train or bus should not be used for domestic purposes.
3) The stoppages for train or bus in both countries should be sufficiently away from localities and the area should be carefully monitored for vectors.
4) Traveler's quarantine should be strictly maintained. Our government should be aware of the factor of migration of infected vectors urgently. If it is ignored, it will be not so late when even a lay man will bother for uncommon diseases like Japanese B encephalitis, chikangunya or other uncommon vector borne diseases as like as dengue today.
The recent outbreake of swaine flu in Bangladesh is a great concern which was first introduced in Dhaka by a infected passenger came from USA through air-port. I think it was not so difficult to prevent entry of such pandemic disease in our country through airport if sufficient measures were taken to quarantine the suspected patient coming from outside of the country.

Health care: Allergy-"CONTACT DERMATITIS"
suggests the cause. It is manifested by chronic eczematous lesion with intense itching in skin of hands or foots or any site of body that remain contact with abnoxious materials for prolong period.
Pic: Contact dermatitis with rubber
It is usually due to contact of our skin to many substance like cosmetics, many metals commonly nickel in watch belt or eye glass frame, plastics, rubber, different dyes specially hair dye, dye used in cloths, spray as aerosol etc.
Even some sorts of light can also be harm full specially for eye causing chronic watering or itching which decrease upon exposure to day light after coming from the indoor.
Here is a case report of watering from eyes of a boy of 12 years. The boy was suffering from watering and itching of both eyes for the last 2 years. Ophthalmologist prescribed him symptomatic treatment with local steroids and antihistamines but problem persisted when drugs discontinued. The family was known to me from the childhood of the boy when there was no ocular problem. During taking history I observed that the onset of the disease coincide with their changing of residence in their new house 2 years before and the patient admitted that his symptoms aggravated when he stayed at home and decreased when he became out his house. So, I became assure that the allergic agent was in side his house. I advised him to change his bed to another room when he felt better than when he was in his old room and advised him to shift his used materials from his old room to new place gradually in 2 to 3 days. Ultimately the culprit was identified that it was his table cloth which was a plastic oil cloth of bright yellowish green colour. As soon as it was removed his room he got cured from the symptoms.
It is important that, any affected person who acquired the disease for the last few weeks or months, should think first of any articles including new bed seat, pillow cover or other dress or any household objects those have being used for last few months or period which coincide with the onset of his or her disease.

Health care: Allergy- how can we prevent it
Allergy is called in medical term, hypersensitivity. We are exposed day to day to many substances like chemicals in the form of cosmetic, household paints, essences or colour materials in our foods or drinks, artificial leather in our shoes, plastic materials used in different objects including toys, plastic or metal belt in watch and so many foreign ( not present in our body)materials which are needed in daily life and different organisms including bacteria, viruses, fungus or parasites.
Allergy most commonly affect the nose, eyes, skin, and lungs. These disorders include atopic dermatitis, contact dermatitis, urticaria Different people show allergy to different substances. One person reacts to a particular substance whether other person do not show any reaction to the same substance.
Few people in a particular family may show allergy, these are called atopic person.
