Intramedullary craniovertebral junction tuberculoma: an uncommon location of a common disease

Central nervous system involvement is observed in no more than 10% of patients with systemic tuberculosis. Although CNS tuberculosis is not rare in endemic countries, such as India, intramedullary tuberculosis is not commonly reported. In this study, we report a case of a 40-year-old female who presented with a six-year history of insidious onset, gradually progressive, asymmetric quadriparesis. She was diagnosed with intramedullary tuberculoma at the craniovertebral junction and showed significant clinico-radiological improvement with medical management alone. To the best of our knowledge, this report describes the first case of intramedullary tuberculoma at the craniovertebral junction to be reported. With the increased availability of MRI in developing countries, it is now possible for clinicians to diagnose this condition without performing a biopsy. It is important for the clinicians in developed countries to be highly suspicious of intramedullary tuberculoma, as there has been a resurgence of CNS tuberculosis due to the emergence of the HIV pandemic

Synthesis of New VO(II), Co(II), Ni(II) and Cu(II) Complexes with Isatin-3-Chloro-4-Floroaniline and 2-Pyridinecarboxylidene-4-Aminoantipyrine and their Antimicrobial Studies

The complexes of tailor made ligands with life essential metal ions may be an emerging area to answer the problems of multi drug resistance. The coordination complexes of VO(II), Co(II), Ni(II) and Cu(II) with the Schiff bases derived from isatin with 3-chloro-4-floroaniline and 2-pyridinecarboxaldehyde with 4-aminoantipyrine have been synthesized by conventional as well as microwave methods. These compounds have been characterized by elemental analysis, molar conductance, electronic spectra, FT-IR, FAB mass and magnetic susceptibility measurements. FAB mass data show degradation of complexes. Both the ligands behave as bidentate and tridentate coordinating through O and N donor. The complexes exhibit coordination number 4, 5 or 6. The Schiff base and metal complexes show a good activity against the bacteria; Staphylococcus aureus, Escherichia coli and Streptococcus fecalis and fungi Aspergillus niger, Trichoderma polysporum, Candida albicans and Aspergillus flavus. The antimicrobial results also indicate that the metal complexes are better antimicrobial agents as compared to the Schiff bases. The minimum inhibitory concentrations of the metal complexes were found in the range 10~40 microg/mL.
