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.

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.

Singapore medical journal 2012;53(6):e114-6
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.

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.

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.

PURPOSE: Conventional instruments are known to result in high numbers of outliers in restoring femoral component rotation primarily due to fixed degree of external rotation resection relative to the posterior condylar line (PCL). Outliers can be reduced by determining the patient specific posterior condylar angle (PCA) preoperatively or intraoperatively. There is a paucity of methods that can be used during surgery for determining the PCA. We propose two simple, real-time methods to determine the PCA and hence to measure the axial anatomical variation during surgery. MATERIALS AND METHODS: The study was conducted using axial computed tomography (CT) scans of the knees of 26 patients. The commercial software K-PACS and our proposed two methods (trigonometric and protractor) were used to measure the angle between the transepicondylar axis and PCL, i.e., PCA. Statistical comparison between the mean angles obtained by K-PACS and our methods were done. RESULTS: The three methods resulted in similar PCAs. The mean PCA measured by the three methods were similar. The mean PCA value measured by the K-PACS, trigonometric method and protractor method was 6.27degrees (range, 0degrees to 12degrees), 6.23degrees (range, 0degrees to 11.11degrees) and 6.31degrees (range, 0degrees to 12degrees), respectively. There were significant correlations between the K-PACS measured PCA and trigonometrically or protractor measured PCA. CONCLUSIONS: Our novel, simple, easily reproducible, real-time and radiation-free PCA measurement methods obviate the need for preoperative CT scan for identification of patient specific PCA.

The Journal of Korean Knee Society 2017;29(1):39-44
PURPOSE: Cadaveric studies have shown that deficiency of the posterior horn of the medial meniscus (PHMM) increases strain on the anterior cruciate ligament (ACL) graft. However, its influence on the clinical and radiological outcome after ACL reconstruction is less discussed and hence evaluated in this study. MATERIALS AND METHODS: This study included 77 cases of ACL reconstruction with a minimum 18-month follow-up. Of the 77 cases, 41 patients with intact menisci were compared clinically and radiologically with 36 patients with an injury to the PHMM that required various grades of meniscectomy. The knees were evaluated using subjective International Knee Documentation Committee (IKDC) score and Orthopadische Arbeitsgruppe Knie (OAK) score. RESULTS: Cases with intact menisci showed better stability (p=0.004) at an average of 44.51 months after surgery. No significant differences were noted in the overall OAK score, subjective IKDC score, and functional OAK score (p=0.082, p=0.526, and p=0.363, respectively). The incidence of radiological osteoarthrosis was significantly higher in the posterior horn deficient knees (p=0.022). CONCLUSIONS: The tendency toward relatively higher objective instability and increased incidence of osteoarthrosis in the group with absent posterior horn reinforces its importance as a secondary stabiliser of the knee.

10.Successful delayed-interval delivery in the presence of clinical chorioamnionitis in the leading twin: A report of two cases
Shobini Sukumaran ; Devendra Kanagalingam
The Medical Journal of Malaysia 2019;74(1):85-86
We present two cases of diamniotic, dichorionic twin
pregnancies in which after the loss of the first foetus in the
setting of clinical chorioamnionitis, both pregnancies were
successfully managed by delayed-interval delivery. A fourstage protocol including aspects of management in this
specific setting is proposed. We consider the importance of
a selection process when managing conservatively,
measures to promote latency and decisions regarding
delivery of the foetuses. Whilst we report successful case
studies of conservative management with delayed-interval
delivery, we support a cautious approach and understand
that in the setting of clinical chorioamnionitis of the
remaining foetus, delivery is necessary.
