A case series of percutaneous tension band wiring technique for fixation of fractures of olecranon and patella

There are several advantages in the treatment of fractures by means of closed reduction. Percutaneous fixation is a type of biological fixation. The aim and objectives of this study are to demonstrate the technique of percutaneous tension band wiring in cases of transverse, non- comminuted olecranon and patella fractures and to decrease the soft tissue dissection, blood loss, chances of infection and to ensure speedy mobilization using the innovative percutaneous fixation technique. This retrospective study includes ten patients of olecranon and ten patients of patella operated by the same surgeon. All patients were operated with percutaneous tension band wiring for olecranon and patella. There were six males and four females with olecranon fractures. There were seven males and three females who suffered patella fractures. The average duration of surgery was 55 minutes and average follow up was 24±6 weeks. The suture removal was done at 2 weeks. All patients had full range of movements at six weeks with significantly improved DASH score and Oxford knee score. None of the patients had any complications. Percutaneous fixation decreases the chances of bleeding secondary to unnecessary soft tissue dissection, thereby decreasing the post-operative morbidity. It also, convincingly, decreases the chances of post-operative infection and promotes early mobilization. Closed reduction with percutaneous fixation is believed to be an innovative, safe, reliable and efficient method of managing these difficult fractures

{5-Methyl-1-[8-(trifluoro­meth­yl)quinolin-4-yl]-1H-1,2,3-triazol-4-yl}(morpholino)methanone

In the title mol­ecule, C18H16F3N5O2, the dihedral angle between the pyridine ring and the fused benzene ring is 4.50 (10)°. The triazole ring makes dihedral angles of 54.48 (12) and 57.91 (11)° with the pyridine and benzene rings, respectively. The morpholine ring atoms are disordered over two positions; the site-occupancy factors are ca 0.53 and 0.47. Inter­molecular C—H⋯F hydrogen bonding is found in the crystal structure. Furthermore, C—H⋯O and C—H⋯N intra­molecular contacts are also present

Surveillance of drug-resistant tuberculosis in the state of Gujarat, India

BACKGROUND: Limited information about the prevalence of drug-resistant tuberculosis (TB) has been reported from India, the country with the world’s highest burden of TB. We conducted a representative state-wide survey in the state of Gujarat (2005 population: 56 million). METHODS: Mycobacterium tuberculosis isolates from a representative sample of new and previously treated smear-positive pulmonary TB (PTB) cases were subjected to drug susceptibility testing (DST) against fi rst-line drugs at a World Health Organization supranational reference laboratory. Isolates found to have at least both isoniazid (INH) and rifampicin (RMP) resistance (i.e., multidrugresistant TB [MDR-TB]) were subjected to second-line DST. RESULTS: Of 1571 isolates from new patients, 1236 (78.7%) were susceptible to all fi rst-line drugs, 173 (11%) had any INH resistance and MDR-TB was found in 37 (2.4%, 95%CI 1.6–3.1). Of 1047 isolates from previously treated patients, 564 (54%) were susceptible to all fi rst-line drugs, 387 (37%) had any INH resistance and MDR-TB was found in 182 (17.4%, 95%CI 15.0–19.7%). Among 216 MDR-TB isolates, 52 (24%) were ofl oxacin (OFX) resistant; seven cases of extensively drug-resistant TB (XDR-TB) were found, all of whom were previously treated cases. CONCLUSION: MDR-TB prevalence remains low among new TB patients in Gujarat, but is more common among previously treated patients. Among MDR-TB isolates, the alarmingly high prevalence of OFX resistance may threaten the success of the expanding efforts to treat and control MDR-TB

Synthetic Strategies and Parameters Involved in the Synthesis of Oligodeoxyribonucleotides According to the Phosphoramidite Method

The phosphoramidite approach has had a major impact on the synthesis of oligonucleotides. This unit describes parameters that affect the performance of this method for preparing oligodeoxyribonucleotides, as well as a number of compatible strategies. Milestones that led to the discovery of the approach are chronologically reported. Alternate strategies are also described to underscore the versatility by which these synthons can be obtained. Mechanisms of deoxyribonucleoside phosphoramidite activation, factors affecting condensation, and deprotection strategies are discussed.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/143633/1/cpnc0303.pd
