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

Recent innovations in the treatment of schizophrenia reflect a growing trend towards
community-based care. Malaysia had in the past few years attempted to deinstitutionalise mental patients
in the mental hospitals. Therefore it is important to conduct research to compare the two groups of
schizophrenia patients (community-based patients against chronic hospitalised patients) to ascertain if
deinstitutionalisation has been beneficial. The main objective of the study was to compare levels of
depression and function in community-based patients against chronic hospitalised patients as depression
is prevalent among schizophrenia patients. This study was cross sectional in nature where data was
collected from 51 inpatients in Hospital Bahagia Ulu Kinta (HBUK) and 23 community-based patients.
Calgary Depression Scale for Schizophrenia (CDSS) and Global Assessment of Functioning scale
(GAF) were the assessment tools used. Community-based patients were found to have significantly
lower scores in the CDSS scale (1.96) as compared to chronic hospitalised patients (4.04); p < 0.01).
They also showed higher functional capability between community-based and hospitalised patients
respectively (74.04 vs 57.92) respectively. (p < 0.001). Community services appeared to be more
effective than long stay in-patient services in preventing depression and promoting better functional
levels.

Objectives: Dhat syndrome is a cultural bound syndrome in which affected individuals have morbid pre-occupation with semen loss in their urine and its impact on the body. Previous studies have explored the symptomatology and perception regarding seminal discharge of such patients while there is lacked of literature on the assessment by quacks and practitioner of alternative and complementary practitioners (ACMP). Therefore, in addition to objectives of previous studies, this study explores the reprehensibility of such practitioners as they may not be giving correct advice to such patients.
Methods: For duration of three months, this mixed method study was conducted in Rohilkhand Medical College campus; individuals were approached both in and outside the Psychiatric Outpatient Department using purposive sampling procedure. ICD-10 diagnostic criterion was used to include affected individual in the study sample. Subsequently, a semi-structured questionnaire to document their socio-demographic data and symptomatology was used. Further, previous consultation to quack, ACMPs and allopathic practitioners other than psychiatrist and advice given to the patient by them was obtained via in-depth interview. The quantitative data was analyzed through proportions whereas qualitative data via thematic analysis.
Results: There were 38 out of 110 with Dhat syndrome. Invariably, they complained of undue concern regarding debilitating effects of seminal discharge and harmful for the body. A total 21.1% had prior consultation to ACMPs and attributing it to masturbation and hot weather. Surprisingly, allopathic practitioners consulted gave incorrect advices.
Conclusion: Dhat syndrome affects individuals irrespective of their social and education background. Sex education among the masses and emphasis for awareness of this syndrome among ACMPs and allopathic practitioners other than psychiatrist is necessary to reduce this cultural bound syndrome.

The effect of methanolic extract of cashewnut (Anacardium occidentale) shell extract was seen on conidial germination of Erysiphe pisi and powdery mildew development in pea (Pisum sativum). Maximum conidial germination inhibition of E. pisi on glass slides was observed at 300 ppm. Similar effect on floated pea leaves was observed after 48 h at the same concentration. Conidial germination on intact untreated pea leaves was also assessed on II and IV nodal leaves while IV and II nodal leaves were treated with the extract and vice versa. There was tremendous reduction in conidial germination on all the nodal leaves. The disease intensity of pea powdery mildew was significantly reduced by methanolic extract of cashewnut shells. Maximum reduction was observed with 200 ppm where 39% disease intensity was recorded in comparison to 96.53% in the control. The phenolic acid content of pea leaves following treatments with this extract varied and no definite pattern was observed. Out of several phenolic compounds, namely, gallic, ferulic, chlorogenic, and cinnamic acids, only gallic acid was found to be present consistently in all the treatments with varied amounts.

5.Olecranon Osteotomy Approach for Complex AO-13C Fractures of Distal Humerus: A Prospective Analysis of 24 Cases
Malaysian Orthopaedic Journal 2019;13(1):30-35
Introduction: Olecranon osteotomy is well described approach for complex intra-articular distal humeral fractures. In this study, we investigated the usefulness and complications of olecranon osteotomy approach for such fractures. We hypothesise that outcome is comparable in young adults and middle age group and also functional outcome is independent of fracture subtype following surgical fixation. Materials and Methods: Between December 2012 and September 2015, twenty-four adult patients (male: 15, female: 9) having mean age of 41.4 years with closed intra-articular fracture (AO-13C) were surgically managed using olecranon osteotomy approach and were followed-up for a mean of 28.5 months (range: 22-35 months). Functional outcome was measured using Mayo Elbow Performance Score (MEPS) and complications were observed. Statistical analysis was done using Student t-test and Kruskal Wallis test. Results: All fractures united by the end of three months. Mean elbow flexion achieved was 123°, mean extension lag was 9° and mean active arc of motion was 114°. Mean MEPS was 87 (excellent: 8, good: 14, fair: 1 and poor: 1). Post-operative transient ulnar nerve palsy was noted in two cases, heterotopic ossification (HO) was in one case, infection in two cases, implant prominence in five and elbow stiffness in three cases. Motion arc was higher in young adults and MEPS was comparable in both age group. Functional outcome was also dependent on fracture subtype. Conclusion: The olecranon osteotomy approach for distal humerus fractures had good functional outcome with fewer complications. Joint congruity and fixation could easily be assessed intraoperatively.

INTRODUCTIONMorbidity and mortality from malignant diseases are usually the result of metastasis. The bone is the third most common site of metastasis.
METHODSThis is a retrospective study of patients with metastatic bone disease who were referred to the Orthopaedic Department of University Malaya Medical Centre, Malaysia, between January 2004 and October 2009.
RESULTSA total of 151 patients (51.0% men, 49.0% women) had metastatic bone disease, with the highest incidence at the age range of 50-59 years. The commonest primary cancer was breast (23.3%), followed by lung (21.2%), prostate (9.3%), thyroid (7.3%) and renal cell carcinoma (5.3%); unknown primary cancer was 6.6%. There was long bone involvement in 52.7% of cases, axial bone in 44.5%, and both long and axial bones in 2.8%. The majority (90.1%) were symptomatic, with pain as the commonest symptom. 106 (70.2%) patients had pathological fractures. Neurological deficit was reported in 90.7% of patients, with 41.1% having extraskeletal metastases. 67.8% of the lesions were osteolytic, 24.3% were sclerotic, and 7.9%, mixed. Palliative and therapeutic interventions were undertaken for 62.0% of patients. The mean survival times were: breast 21.0; thyroid 20.7; prostate 20.3; lung 16.0; and unknown primary cancer 32.6 months.
CONCLUSIONIn our study, breast and lung cancers were the commonest primary cancers in metastatic bone disease. Most patients had more than one site of involvement, pain at presentation and pathological fractures. Surgery is beneficial to relieve pain and improve function and neurology. Duration of survival depends on the type of primary cancer and whether systemic metastasis is present.

Powdery mildews on over 40 plants in Bangalore were screened during July-December of 2003~2008. Isolates from mycoparasitised Oidium caesalpiniacearum of Bauhinia purpurea comprised Lasiodiplodia theobromae, in addition to Ampelomyces quisqualis. Koch's postulates were satisfied to establish the mycoparasitism of L. theobromae. This is the first report that L. theobromae acts as a mycoparasite of a powdery mildew.

Current selection guideline for CRT uses broad QRS duration (>120 ms) as a marker for ventricular
dyssynchrony. However, more recent data supports mechanical marker specifically measured
by Tissue Doppler Imaging (TDI) as a better criterion to predict response to CRT. Sixty seven
patients with significant left ventricular dysfunction (EF less than 40%) and narrow QRS complex
were prospectively enrolled. They underwent Tissue Doppler Imaging (TDI) study to evaluate
intraventricular mechanical dyssynchrony. Dyssynchrony index which is defined as standard
deviation of time to peak systolic velocity in twelve ventricular segments was measured. A value
greater than 32.6 is taken to reflect significant ventricular dyssynchrony. Overall 38 patients
(56.7%) demonstrated significant dyssynchrony. There was no significant correlation between QRS
duration and the Ts-SD-12 (r = 0.14, p = 0.11). Ventricular mechanical dyssynchrony is common
in patients with normal QRS duration. Therefore, QRS duration alone will miss a substantial
proportion of suitable patients for CRT and therefore deny them this adjunct therapy. We propose
echocardiographic parameters, specifically TDI, to be included in patient selection criteria for CRT.

Management of maxillofacial trauma includes primary care, in which diagnosis and management of dentoalveolar injury play a vital role. Due to the impact sustained during a maxillofacial injury (whether direct or indirect), dentoalveolar injuries can occur, leading to fracture and displacement of teeth and associated alveolar bone into the surrounding soft tissues and associated structures, such as the maxillary sinus, nasal cavity, upper respiratory tract, tracheobronchial tree, or gastrointestinal tract. Undiagnosed displaced teeth may cause complications such as airway obstruction. This paper reports a case of displaced teeth in the nasal cavity and gastrointestinal tract and highlights the management protocol for displaced teeth secondary to maxillofacial trauma.
