Forty mycobacterial strains comprising clinical Indian isolates of Mycobacterium tuberculosis (28 field isolates +1H37 Rv) and Mycobacterium bovis (10 field isolates +1 AN5) were subjected to restriction fragment length polymorphism analysis (RFLP) using IS6110 and IS1081 probes. Most of these strains originated from dairy cattle herd and human patients from Indian Veterinary research Institute (IVRI) campus isolated from the period of 1986 to 2000. Our study showed presence of 8 copies of IS6110 in most of the M.tuberculosis (96.6%) strains irrespective of their origin with the exception of one M.tuberculosis strain with presence of an extra copy (3.4%). All M.bovis strains showed a single copy of IS6110 on the characteristic 1.9kb restriction fragment. RFLP analysis with IS1081 invariably showed the presence of 5 copies in all isolates of M.bovis and M.tuberculosis at the same chromosomal location. Similarity of IS6110 RFLP fingerprints of M.tuberculosis strains from animals and human suggested the possibility of dissemination of single M.tuberculosis strain among animals as well as human. It was not possible to discriminate within the isolates of either M.tuberculosis or M.bovis, when IS1081 was used as target sequence. The IS6110 RFLP is a valuable tool for disclosing transmission chain of M. tuberculosis and M. bovis among humans as well as animals

Objective: The present report embodies detailed diagnostic features of five important Red listed Swertia species for easy and authentic identification along with HPTLC fingerprinting using the c-glucoxanthone mangiferin as a biomarker. The key objectives of this study were to reduce indiscriminate harvesting of different Swertia species from its natural habitat and the development of a reliable kit based on HPTLC fingerprinting to reduce adulteration in commercial trade. Methods:Chromatography was performed on Silica gel 60 F254 TLC plates with ethyl acetate-glacial acetic acid-formic acid- water- 100:11.0:11.0:26 as mobile phase. Densitometric measurement was performed at λ=254 nm. The method was found to be simple, reliable, precise and convenient for routine analysis. Results: Although mangiferin was detected in substantial amount from all populations of Swertia chirata irrespective of their geographical locations and to a lesser degree in Swertia nervosa, the biomarker was totally absent in Swertia bimaculata, Swertia dilatata and Swertiapaniculata. Conclusions:Floral morphology can be effectively used for the construction of an easy identification tool that can be utilized at the field level to screen out Swertia chirata from other closely related species that flower at the same time along with Swertia chirata. High Performance TLC using mangiferin as a biomarker can be utilized for quality screening and checking adulteration among different species and populations of Swertia.

Cervical stenosis is a challenging condition that often recurs despite intervention. Multiple therapeutic options have been described, but a clearly effective and reliable treatment method has yet to be identified. Patients with recurrent stenosis are at risk of developing severe complications such as chronic pelvic pain and infertility. We describe a case of congenital cervical stenosis with secondary haematometra in which repeated cervical dilatation, hysteroscopic canalisation and administration of medications to retard endometrial development were unsuccessful in relieving the obstruction and preventing re-accumulation of menstrual blood. Total hysterectomy was eventually mandated by spontaneous rupture of the haematometra.

Background: Unsafe injection practice can transmit various blood borne infections. The aim of this study was to assess the knowledge and practice of injection safety among injection providers, to obtain information about disposal of injectable devices, and to compare the knowledge and practices of urban and rural injection providers. Methods: The study was conducted with injection providers working at primary health care facilities within Kaski district, Nepal. Ninety-six health care workers from 69 primary health care facilities were studied and 132 injection events observed. A semi-structured checklist was used for observing injection practice and a questionnaire for the survey. Respondents were interviewed to complete the questionnaire and obtain possible explanations for certain observed behaviors. Results: All injection providers knew of at least one pathogen transmitted through use/re-use of unsterile syringes. Proportion of injection providers naming hepatitis/jaundice as one of the diseases transmitted by unsafe injection practice was significantly higher in urban (75.6%) than in rural (39.2%) area. However, compared to urban respondents (13.3%), a significantly higher proportion of rural respondents (37.3%) named Hepatitis B specifically as one of the diseases transmitted. Median (inter-quartile range) number of therapeutic injection and injectable vaccine administered per day by the injection providers were 2 (1) and 1 (1), respectively. Two handed recapping by injection providers was significantly higher in urban area (33.3%) than in rural areas (21.6%). Most providers were not aware of the post exposure prophylaxis guideline. Conclusion: The knowledge of the injection providers about safe injection practice was acceptable. The use of safe injection practice by providers in urban and rural health care facilities was almost similar. The deficiencies noted in the practice must be addressed.

Migration of coils during endovascular procedures is a rare, but well-known complication. We are reporting two cases of successfully retrieving migrated coil using detachable intracranial stent. In both of our cases there was distal migration of coil during the intracranial aneurysm coiling procedure. The Solitaire® AB stent (Covidien, Irvine, CA, USA) was used to retrieve those coils. The stent was passed distal to the migrated coil using standard technique. It was then partially deployed and gradually withdrawn along with the entangled coil. Coil retrieval using the fully retrievable intracranial stent is a very simple, safe and easily available alternative for retrieval of distally migrated coil.

Triceps rupture is the least common among all tendon injuries. The usual mechanism of injury is a fall on an outstretched hand, although direct contact injuries have also been reported to cause this injury. The diagnosis of acute triceps tendon rupture may be missed, which can result in prolonged disability and delayed operative management. We presented three cases of acute triceps tendon rupture each at different site showing the spectrum of injury to the muscle and mechanism of injury and management were also discussed.

PURPOSESoft tissue healing is of paramount importance in distal tibial fractures for a successful outcome. There is an increasing trend of using anterolateral plate due to an adequate soft tissue cover on ante- rolateral distal tibia. The aim of this study was to evaluate the results and complications of minimally invasive anterolateral locking plate in distal tibial fractures.
METHODSThis is a retrospective study of 42 patients with distal tibial fractures treated with minimally invasive anterolateral tibial plating. This study evaluates the bone and soft tissue healing along with emphasis on complications related to bone and soft tissue healing.
RESULTSFull weight bearing was allowed in mean time period of 4.95 months (3-12 months). A major local complication of a wound which required revision surgery was seen in one case. Minor complications were identified in 9 cases which comprised 4 cases of marginal necrosis of the surgical wound, 1 case of superficial infection, 1 case of sensory disturbance over the anterolateral foot, 1 case of muscle hernia and 2 cases of delayed union. Mean distance between the posterolateral and anterolateral incision was 5.7 cm (4.5-8 cm).
CONCLUSIONThe minimally invasive distal tibial fixation with anterolateral plating is a safe method of stabilization. Distance between anterolateral and posterolateral incision can be placed less than 7 cm apart depending on fracture pattern with proper surgical timing and technique.

Fall from height is a common cause of unintentional injuries in children and accounts for 6% of all trauma-related childhood deaths, usually from head injury. We report a case of a 2-year-old child with multiple fractures of the bilateral lower limbs due to this reason. A child fell from a height of around 15 feet after toppling from a balcony. He developed multiple fractures involving the right femoral shaft, right distal femoral epiphysis (Salter Harris type 2), right distal metaphysis of the tibia and fibula, and undisplaced Salter Harris type 2 epiphyseal injury of the left distal tibia. There were no head, abdominal or spinal injuries. The patient was taken into emergency operation theatre after initial management which consisted of intravenous fluids, blood transfusion, and splintage of both lower limbs. Fracture of the femoral shaft was treated by closed reduction and fixation using two titanium elastic nails. Distal femoral physeal injury required open reduction and fixation with K wires. Distal tibia fractures were closely reduced and managed nonoperatively in both the lower limbs. All the fractures united in four weeks. At the last follow-up, the child had no disability and was able to perform daily activities comfortably. We also proposed the unique mechanism of injury in this report.

INTRODUCTIONIn the United Kingdom, caesarean section (CS) rates have increased from 9% of deliveries in 1980 to 21% in 2001. A similar increase in CS rates has been seen in many developed countries. This is beyond the World Health Organisation's (WHO's) recommended level of 15%. This is a worrying trend as the risks of placenta previa, placenta accreta, hysterectomies, bladder and bowel injuries are increased with subsequent CS. We aim to ascertain the commonest indications for CS in a tertiary hospital and make recommendations to decrease future CS rates.
MATERIALS AND METHODSThis retrospective analysis compares the 5 most common indications for CS in 1999 and 2009. CS rates in the 2 study periods are tabulated and analysed as well.
RESULTSIn the first study period between January and December 1999, there were 2048 deliveries of which 365 were via CS. In the second study period of a decade later from January to December 2009, there were 1572 deliveries of which 531 were via CS. This gives an increase in CS rate from 17.8% in 1999 to 34% in 2009. The main indications for CS in 1999 were: cephalopelvic disproportion (18.6%), breech (14.2%), non-reassuring fetal status (11.8%), 1 previous CS (11.2%) and pregnancy-induced hypertension/pre-eclampsia/eclampsia (6.6%). The main indications for CS in 2009 were: 1 previous CS (18.1%), non-reassuring fetal status (12.2%), cephalopelvic disproportion (10.5%), 2 or more previous CS (7.9%) and breech (7.7%).
CONCLUSIONThere is a significant increase in CS rates over the last decade with an increased percentage of CS done because of a previous CS. This is associated with increased risk of complications as well. Recommendations are suggested with the view to decrease future CS rates.

Nutrient recovery from source-separated human urine has attracted interest as it is rich in nitrogen and phosphorus that can be utilized as fertilizer.However,urine also contains pharmaceuticals,steroid hormones,etc.and their removal is crucial as they have detrimental effects on the environment and human health.The current study focuses on investigating the degradation of pharmaceuticals using a double-chamber microbial fuel cell (MFC).Urine was spiked with four pharmaceuticals (trimethoprim,lamivudine,levofloxacin,and estrone) at a concentration of 2 μg/mL.The MFC was operated for 7 months in batch mode with this spiked urine as feed.The degradation efficiency of the MFC was studied,for which a selective liquid chromatography-tandem mass-spectrometric method was developed for the quantitation of compounds used in the spiking experiments and was validated with a lower limit of quantification of 0.39 ng/mL.The maximum removal rate achieved was 96%± 2%.The degradation mechanism involved processes like sorption and anoxic biodegradation.The voltage curve obtained showed that the presence of pharmaceuticals had an initial negative impact on power generation along with increased organic content;however,after the reactor acclimatization,increased power output was achieved with maximum organics removal at 30 h of retention time.This work opens a new perspective for the anoxic biodegradation of pharmaceuticals and can be useful in future bioremediation studies.
