Diagnosis and Prevention of Tuberculosis

-
Tuberculosis is a dreaded disease in third world countries. It is considered disease of poverty. The disease generally occurs due to close contact with the infected person and the droplets causing infection. Tuberculosis of the lungs, known as Pulmonary Tuberculosis is most common. There is generally a history of tuberculosis in the family. The child suffers from low grade and sometimes high grade fever. There is history of weight loss for months. The fever also continues for months, and does not respond to general antibiotics. There is a continuous dry cough though it is not too severe. Sometimes, you can feel lymph glands like nodules. These lymph glands are matted, hard and rubbery. They may also occur in the axilla.

According to Dr. Mubina Agboatwalla-A Child Specialist in Karachi, X-Ray of chest is quite diagnostic in this regard. The physician by looking at the X-Ray can make a clinical diagnosis of tuberculosis. In addition, the ESR is raised. Another diagnostic test is Mantoux Test. This is skin test which is read after 72 hours.  A red induration of more than 10 mm is diagnostic.  Treatment should be started immediately. The total duration of the treatment is 6-8 months. For the initial 2 months, three drugs are given followed by two more drugs. The important thing is to undergo regular treatment without any gaps. This is known as Direct Observation Treatment Strategy (DOTS). The medicines generally cause nausea, anorexia and weakness. The child may pass orange colored urine. Symptoms start to subside after 1 month. Patients tend to stop treatment which is wrong as relapse takes place. Treatment should be completed. Prevention is very important. BCG vaccinations should be given to babies soon after birth which provides protection against tuberculosis.

  Q. Do children develop kidney stones ? If yes then what are the symptoms and how can they be treated. A. Yes children as young as one year can develop kidney stones. Generally the stones are small and are found either in the renal pelvis or ureter. As they move down the ureter they can cause severe shooting pain in the back or in the flanks. This generally occurs when the child does not drink enough water. Atleast 8 glasses of water should be taken. Renal colic happens specially in the summer months. The urine may contain small quantities of red blood cells. It may or may not be accompanied by a urine infection. The pain is extremely severe and a shooting type of pain. There may be associated vomiting. Plenty of water should be given to flush out the stones. In rare cases laser surgery can be done. Website - https://www.drmubinaagboatwalla.com/
