Impact of BMW Segregation Training Program on Hospital Infection Control in a South Indian Hospital

This study aimed to investigate anaerobic co-digestion of palm oil mill effluent (POME) with cassava peels (CP) and cabbage waste (CW) for biomethane production. The anaerobic digestion (AD) in 10L capacity bioreactors loaded separately with three different ratios (3L/ 520g, 3L/ 600g and 3L/ 680g) of POME/CP, POME/CW and POME only (control) was operated under ambient temperature (25 - 36?C) and pH range of 6.5 - 8.5 for 45 days. Standard methods were adopted in the characterization of the bioreactor feeds and microbiological study. The biomethane content of the biogas was determined using Gas Chromatography (GC). The results showed the presence of Escherichia coli, Staphylococcus, Pseudomonas sp, Bacillus sp Salmonella sp among others. Fungal isolates identified include Saccharomyces, Aspergillus, Rhizopus, Penicillum, and Geotrichum species. The mean cumulative biogas yield recorded in bioreactors charged with POME/ CP 520g, POME/ CP 600g, POME/ CP 680g and POME/CW 520g, POME/CW 600g, POME/CW 680g were 7.08, 5.18, 9.06, 9.13, 9.28 and 8.33 dm3, respectively, whereas POME alone (control) was 4.64 dm3. The best performance in biogas yield was exhibited by POME/CW 600g (9.28dm3), and the highest percentage biomethane content (68.80%). Analysis of variance (ANOVA) revealed a significant difference (P ? 0.05) in biogas yield in all the treatments compared to control (POME alone) except in POME/CP 3L: 520g and POME/CP 3L: 600g. The results have shown that biogas production and biomethane content could be efficiently improved via co-digestion process, depending on the substrates used as feedstock.

Recurrent oral submucous fibrosis with nil mouth opening surgical management and reconstruction with bilateral nasolabial flap: A case report and review of literature

Oral submucous fibrosis [OSF] is a premalignant condition characterized by inflammation and progressive fibrosis of submucosal tissue, resulting in trismus. It is associated with chewing of areca nut in betel quid. Mortality rate is significant because it transforms into oral squamous cell carcinoma at a rate of 2.3%–7.6%. The aim of this article is to share our experience in managing a case of recurrent oral submucous fibrosis with nil mouth opening by surgical excision, coronoidotomy, and reconstruction of buccal defect using bilateral inferiorly based nasolabial flap, followed by active oral physiotherapy. The patient had reached an acceptable mouth opening with no further recurrence. The patient was observed closely for any malignant transformation. Surgical excision of bands and coronoidotomy followed by reconstruction with nasolabial flaps and active physiotherapy in the postoperative period remains a good option for recurrent and advanced cases of OSF with acceptable functional and cosmetic results.

Performance of rapid influenza diagnostic tests (QuickVue) for Influenza A and B Infection in India.

Background: Rapid point-of-care (POC) tests provide an economical alternative for rapid diagnosis and treatment of infl uenza, especially in public health emergency situations. Objectives: To test the performance of a rapid infl uenza diagnostic test, QuickVue (Quidel) as a POC test against a real-time polymerase chain reaction (RT-PCR) assay for detection of infl uenza A and B in a developing country setting. Study Design: In a prospective observational design, 600 patients with infl uenza-like illness (ILI) or with severe acute respiratory illness (SARI) who were referred to the Infl uenza Clinic of a tertiary care hospital in Srinagar, India from September 2012 to April 2013, were enrolled for diagnostic testing for infl uenza using QuickVue or RT-PCR. All infl uenza A-positive patients by RT-PCR were further subtyped using primers and probes for A/H1pdm09 and A/H3. Results: Of the 600 patients, 186 tested positive for infl uenza A or B by RT-PCR (90 A/ H1N1pdm09, 7 A/H3 and 89 infl uenza B), whereas only 43 tested positive for infl uenza (infl uenza A = 22 and infl uenza B = 21) by QuickVue. Thus, the sensitivity of the QuickVue was only 23% (95% confi dence interval, CI: 17.3-29.8) and specifi city was 100% (95% CI: 99.1-100) with a positive predictive value (PPV) of 100% (95% CI 91.8-100) and a negative predictive value (NPV) of 74.3% (95% CI: 70.5-77.9) as compared to RT-PCR. Conclusions: The high specifi city of QuickVue suggest that this POC test can be a useful tool for patient management or triaging during a public health crisis but a low sensitivity suggests that a negative test result need to be further tested using RT-PCR.

Reuse of Cardiac Rhythm Control Devices: A Review.

Cardiac rhythm control devices i.e. pacemakers, implantable cardioverter-defibrillators (ICDs) and biventricular pacemakers are at times lifesaving treatment and prevention of arrhythmia. But, despite definite indications, many people in the developing countries cannot afford these devices due to high cost, and succumb to premature death. On the other hand, after implantation, pacemakers and ICDs are sometimes underutilized because of premature explantation due to death of the recipient, device infection, or upgradation, leaving a considerable extent of serviceable battery life unused. Majority of these explanted devices are simply thrown away. Though made for single use, a growing body of evidence indicates the safety, efficacy and feasibility of reimplantation of the prematurely explanted devices in patient in need who is otherwise unable to afford a new one. Patients, physicians, morticians, and even the general public support the idea of device donation and recycling. A number of organizations around the world have engaged themselves in this benevolent effort, and t he feasibility of device reutilization programme has already been established. However, some logistic, legal and ethical concerns are yet to be solved. The statutory bodies and professional organizations should address the issue of device recycling to solve the unsolved issues and formulate standard practice guidelines. In that case, such medical wastes may turn into invaluable resources, and help ensuring equitable medical care throughout the world.

Interrelationship among testicular cells in wall lizard Hemidactylus flaviviridis (Rüppell): an ultrastructural seasonal and experimental study.

The present study was aimed at investigating ultrastructure of different testicular cells and their interactions through various junctional specializations during different phases of reproductive cycle in wall lizard H. flaviviridis to develop an integrated approach of cell-cell interaction in control of testicular functions. Specialized steroid synthesizing cell organelles such as smooth endoplasmic reticulum (SER) and long slender mitochondria with tubulo-vesicular cristae were predominantly seen in Leydig as well as Sertoli cells during spermatogenically active phase, suggesting their active involvement in steroid biosynthesis. Peritubular cells also exhibited marked seasonal variations. Multi-layered fibroblast-like peritubular cells during regressed phase became single layered myoid-like during spermatogenically active phase. The presence of various types of junctions, including gap and tight junctions (occluding junctions) and adhering junctions such as desmosomes, septate-like junction, ectoplasmic specializations and tubulo-bulbar complexes, were demonstrated among testicular cells in wall lizard H. flaviviridis. However, the nature and degree of junctional (environmental) interaction varied with the reproductive state of the wall lizard. Further, administration of dihydrotestosterone in wall lizards during regressed phase resulted in increase of lipid droplets in Leydig cells and accumulation of germ cell debris in seminiferous tubules. Some of the Sertoli cells were seen darker in response to testosterone treatment probably due to its inhibitory effect on lipid metabolism. These results suggest that testosterone either directly or via inhibiting pituitary basal gonadotropin secretion has suppressive effect on testicular cells.

Group B streptococcal bacteremia in an adult: a case report from India.

The incidence of group B streptococcal bacteremia in adults has increased in recent years, particularly in patients with severe underlying diseases. However, group B still remains an unusual pathogen in adults in developing countries. We report a case of group B streptococcal bacteremia in a non-pregnant adult, the only case reported in our hospital. The organism was only isolated from the blood and responded to specific therapy.
