It is prudent to advise all women of child-bearing age to avoid getting pregnant until TB treatment is completed. Aminoglycosides (STM, capreomycin, amikacin) should be used with caution in pregnancy, because they may cause deafness in the unborn child. The attending physician must weigh the benefits of treating the mother against the potential harm to the baby, and good outcomes have been reported in children whose mothers were treated with aminoglycosides. Experience in Peru shows that treatment for MDR-TB is not a reason to recommend termination of pregnancy, and that good outcomes are possible. Kidney disease
People with kidney failure have a 10 to 30-fold increase in risk of getting TB. People with kidney disease who are being given immunosuppressive medications or are being considered for transplant should be considered for treatment of latent tuberculosis if appropriate. Aminoglycosides (STM, capreomycin and amikacin) should be avoided in patients with mild to severe kidney problems because of the increased risk of damage to the kidneys. If the use of aminoglycosides cannot be avoided (e.g., in treating drug-resistant TB) then serum levels must be closely monitored and the patient warned to report any side-effects (deafness in particular). If a person has end-stage kidney disease and has no useful remaining kidney function, then aminoglycosides can be used, but only if drug levels can be easily measured (often only amikacin levels can be measured). In mild kidney impairment, no change needs to be made in dosing any of the other drugs routinely used in the treatment of TB.
Infection of the cysts in this region can compress trachea, causing respiratory problems, or it can compress the oesophagus, causing dysphagia, and irritating the sternocleidomastoid muscle, causing torticollis. Third and fourth branchial cleft cysts are rare, usually consisting of 2% of all branchial arch abnormalities, located below the second branchial arch. They usually have sinus tracts that start from the anterior neck at the thyroid gland until pyriform sinus posteriorly. If infected, it can cause acute infectious thyroiditis in children and if enlarge rapidly, can cause tracheal compression in children. Treatment
Conservative (i.e. no treatment), or surgical excision. With surgical excision, recurrence is common, usually due to incomplete excision. Often, the tracts of the cyst will pass near important structures, such as the internal jugular vein, carotid artery, or facial nerve, making complete excision impractical due to the high risk of complications.
