Background: Due to the lack of a standard case definifion and the diffuculty in estabilishing a definitive diagnsos, TB in children needs increasing attention by physicians caring for pediatric patients. Tuberculous meningitis (TBM) is the most serious form of extrapulmonary tuberculosis that is associated with significant morbidity and mortality rate in the pediatric age group, especially in infants. This descriptive study was conducted in an University hospital, at the South of Turkey, from May 1999 to May 2019. Methods: The hospital records of 26 TBM infant that was diagnosed at our hospital were retrospectively evaluated. The epidemiological findings (age, gender, family history of TB, tuberculin skin test results, status of BCG scaring), stage of TBM at admission and clinical, laboratory and radiological features were collected. Results: Of the 26 infants, 61.5% were male and mean age of the patients was 7,65±2,6 (range, 3-12 months). The history of close contact with an infected adult was encountered in 73.1% (19 infant) of the cases. Only 69.2% of the patients (18 case) had a BCG scar. The prodromal stage (period between the onset of symptoms to hospital admission) ranged from 4 days to 180 days (39±51.3). 2 cases were defined as stage I, 10 cases as stage II and 14 cases as stage III TBM. Only two patients were initially positive for PPD test. While no neurological findings were found in 2 patients (diagnosed as stage I), neurologic findings at the time of admission included increased intracranial pressure; alteration in consciousness (92.3%), seizures (88.4%), vomiting (61.5%) cranial nerve palsy (23%), irritability 19.2%, hemiplegia 15.3% and meningeal signs (7%, only 2 patients). The presence of hepatomegaly 26.9 % and/or splenomegaly 11.5 % and/or extrapulmonary lymphadenopathy 3.8 % in nearly half of the cases suggested that totally 42,2% of cases had disseminated of tuberculosis. On admission, 46.1% of the patients were noted to have hyponatremia. Microbiologic confirmation was established in eleven (42.3%) of the 26 infant. A positive CSF culture for Mtb and/or smear for AFB and/or PCR was obtained in only 5 (19.2%) patients, whereas 3 of the cases had accompaining gastric aspirate examination positivity. Pulmonary consolidation in 14 (53.8%) patients, miliary patern in 10 (41.6%) and pulmonary hilar lymphadenopathy in only 5 (20.8%) patients. 23 (88.4 %) had hydrocephalus, 15 (57.6 %) infarction, 10 (38.4 %) basilar meningitis and 9 (34.6%) tuberculomas. Empiric anti-tuberculosis treatment was instituted in all, at a median of 3 days (range 1-15 days) following admission. 8 (30.7%) died, 3 (11.5%) recovered completely, and 15 (57.6%) recovered with sequelae. 12 case (2 died) of the infants had required ventriculoperitoneal shunting. Conclusion: As early diagnosis and specific treatment appears to prevent serious complications and reduce mortality, a high index of suspicion among pediatricians is especially required in an infant with an atypical picture suggestive of tuberculosis infection.

We evaluated the incidence rate of culture-positive central nervous system tuberculosis (CNS TB) in France in 2007 and its time trend between 1990 and 2007. We used a capture–recapture analysis by using data recorded in 2007 by the mandatory notification system and the national network of the National Reference Centre (NRC). The 2007 sensitivity of the NRC was 79·4%. The previous sensitivity for 2000 (75·6%) and that for 2007 yielded a pooled estimate of 77·4% (95% confidence interval 64·8–88·0), which was used to extrapolate the number of culture-positive CNS TB cases from those reported in four surveys (1990, 1995, 2000, 2007). The extrapolated number of culture-positive CNS TB cases fell from 90 to 35 between 1990 and 2007, and the extrapolated incidence rates fell from 1·6 to 0·55 cases/million (P < 0·001). This favourable trend should be closely monitored following the change of the BCG vaccination policy in 2007. [ABSTRACT FROM AUTHOR]

Background: Central nervous system tuberculosis remains a prevalent problem in developing countries. Also, this disease has been an important problem in developed countries due to the increased incidence of acquired immunodeficiency syndrome. Tuberculosis of the central nervous system is seen in 10% of immunocompetent patients with primary tuberculosis. Case Report: We report two patients with tuberculoma in the central nervous system. The first case had a lesion located in the medulla oblongata, and the second case had a lesion in the medulla spinalis between the 5th cervical and 1st thoracic vertebral level. Both of these patients underwent surgery. Conclusion: CNS tuberculomas may not always show typical magnetic resonance imaging (MRI) signs, but when a neurosurgeon encounters a brown- yellow rubber-like lesion that is easily extirpated from the glial tissue, tuberculoma should be considered; anti-tuberculous and corticosteroid therapy should be initiated as soon as possible to prevent meningitis and the immune-mediated destructive effects of tuberculosis on the CNS. Whether or not anti-tuberculous therapy is continued can be decided upon by following definitive pathologic diagnosis. [ABSTRACT FROM AUTHOR]
