Results of management of spinal tuberculosis according to middle path regime and short course chemotheraphy
Background: Vertebral tuberculosis is the most common form of skeletal tuberculosis and it contributes about 50 percent of all cases of skeletal tuberculosis. The purpose of this study is to delineate the importance of middle path regime and short course chemotheraphy in the management of spine tuberculosis.Methods: A prospective study was conducted which included 44 patients diagnosed as tuberculous spondylitis. Management was started as per middle path regime and drugs were given as per the revised national tuberculosis control program (RNTCP) regime category I under directly observed treatment, short-course (DOTS) therapy. Specimen was collected and studied for smear, culture, antibiotic sensitivity and histopathology. ATT was stopped at the end of 6 months as per DOTS schedule and MRI was done at the end of therapy.Results: Dorsal spine lesions were found in 33 patients. 8 patients were smear positive and 38 patients were culture positive of whom 26 patients were sensitive to first line ATT drugs. 12 patients had MDR tuberculosis and were sensitive to 2nd line ATT drugs. 6 patients having negative culture were diagnosed from histopathology. All patients on 1st line ATT had satisfactory result. Only 8 patients with MDR tuberculosis recovered neurologically. Conclusions: It is mandatory to do obtain tissue biopsy and examine culture, sensitivity and histopathology. Recently there is an increasing tendency in multidrug resistance cases and total drug resistant cases. By doing culture and sensitivity of the specimen we can find out the number of MDR cases and initiate proper drug regimen to avoid further complication and mortality
Design and Modelling of PWM Based Interleaved Boost Converter for PEMFC(Proton Exchange Membrane Fuel Cell)
Fuel cells are a family of technologies that generate electricity through electrochemical process rather than combustion. Fuel cell is continuously produce electricity as along as fuel is supplied and the catalyst remains active. Fuel cells provide major environmental, energy and economic benefits that advance critical national goals. Proton Exchange Membrane fuel cell (PEMFC) is one of the promising technologies for the distributed power generation. For designing high efficiency fuel cell power systems, a suitable DC-DC converter is required. Interleaved boost converter (IBC) is a better solution for fuel cell systems, due to improved electrical performance, reduced weight and size. Due to low temperature and use of precious metal based electrodes PEMFC cell must operate on pure hydrogen. In this paper, the electrochemical modelling of a Proton Exchange Membrane Fuel Cell (PEMFC) has been carried out. The type of the conversion structure is a boost, increasing the voltage delivered by the fuel cell and controlled by a PWM signal. After modelling the converter, it is connected to the fuel cell

Arthroscopic resection of dorsal wrist ganglion
Background: The management of dorsal wrist ganglion ranges from benign neglect to surgical excision. The purpose of this study was to study the results of arthroscopic resection of dorsal wrist ganglion.Methods: Twenty one patients who had undergone arthroscopic dorsal wrist ganglion excision and a minimum of 3 months follow up were included. The preoperative complaint of cosmesis, pain, and duration of swelling, wrist range of motion and size of the ganglion were noted. The duration the patient took to return to a painless wrist with full range of motion was noted. Patient satisfaction with respect to cosmesis and function was noted.Results: The mean age was 23.3 years (range: 13 to 35 years). Pre-operative wrist pain was present in 17 patients and cosmesis was a complaint in 18 patients. 5 patients had a pre-operative restricted range of motion. The mean duration and size of the ganglion was 2.6 months (range: 2 to 4 months) and1.8cm (range: 1 to 3 cm) respectively. The mean duration of follow up was 14.6 months (range: 3 to 24 months). Arthroscopically, dorsal synovitis was present in 10 patients, triangular-fibro-cartilage-complex (TFCC) tear in 2 patients and chondral damage in 1 patient. The ganglion stalk was visualized in 14 patients. Complete painless wrist range of motion was obtained by 20 patients by 3 weeks post-operative. One patient had a recurrence. All the remaining patients were satisfied cosmetically and functionally with the results.Conclusions: Arthroscopic resection is an effective treatment modality for symptomatic dorsal wrist ganglion with good functional and cosmetic results
Assessment of functional outcome of surgical management of proximal humerus fracture treated with PHILOS plate
Background: Proximal humeral fractures were treated conservatively in the past and often had compromised functional results. With the advancement of surgical techniques, these fractures, especially displaced, are now more often managed operatively; to meet the needs of the patient, provide early rehabilitation and better functional outcome. The aim of this study was to assess the functional outcome of operative management of proximal humeral fractures with Philos plate fixation.Methods: In this prospective study, 30 patients aged 19-75 years (mean age 47.1 years) with fractures of the proximal humerus, including two-, three-, and four-part fractures, were treated by open reduction internal fixation with Philos plating. Patients’ functional outcomes were evaluated based on subjective (35 points) and objective (65 points) parameters, as per the constant scoring system.Results: Functional outcome based on the constant scoring system of the patient at 6 month follow-up were compared. Excellent results were seen in 12 patients (40%), 2 had very good results (6.66%), 9 patients were having good (30%) and 6 had fair (20%) functional outcome. One patient had poor functional results (3.33%). Avascular necrosis (AVN) of the humeral head was observed in one patients.Conclusions: Philos plate fixation for proximal humeral fractures provides good stable fixation with good functional outcome and is a feasible option.
Arthroscopic fixation of anterior cruciate ligament tibial avulsion fractures: the suture “bridge” pull out technique and evaluation of results
Background: Tibial anterior cruciate ligament (ACL) avulsion fractures are a common injury in children and adolescents. Operative treatment is indicated for type 2, 3 and 4 fractures. Arthroscopic fixation is the preferred method and numerous fixation options are described. The purpose of this study is to evaluate the results of a new technique of arthroscopic fixation.Methods: A retrospective study was done involving twelve patients having displaced ACL tibial avulsion fractures. The arthroscopic suture “bridge” pull out technique was used to fix these fractures. Patient symptoms like knee pain, locking, clicking, sensation of giving way and clinical signs like tenderness, range of motion, Mc Murray’s test, stability test and Lysholm knee scores were evaluated pre operatively and post operatively at 3 months and 6 months. Patient satisfaction was noted at latest follow up.Results: One patient had type 2, 7 patients had type 3 and 4 patients had type 4 tibial ACL avulsion fractures. All the fractures united and all patients achieved full knee range of motion by 2 months post-operative. The clinical symptoms and signs improved post operatively. The mean Lysholm knee score at 3 months follow up was 88.8 and at 6 months follow up were 98.8. At latest follow up, all the patients were satisfied with their knee function. Conclusions: The arthroscopic suture “bridge” pull out technique is an effective method for fixation of ACL tibial avulsion fractures with respect to knee stability, range of motion and resumption of pre injury activity level
Clinical and Radiological Outcomes after Reducing Adult Lytic High-Grade Spondylolisthesis Using a Hybrid Technique: Combination of Percutaneous Pedicle Screws with Midline Microscopic Transforaminal Decompression
Study Design Retrospective study. Purpose To analyze the results and effectiveness of percutaneous screws (PS) with midline microscopic transforaminal decompression (MTFD) technique in reducing adult stiff lytic high-grade spondylolisthesis (HGSL) and compare it with the conventional technique. Overview of Literature Pedicle screw cannulation and segmental kyphosis negotiation are surgical challenges in HGSL. Open reduction is the preferred approach. PS have the advantage of optimized trajectory and minimized soft tissue exposure. The role of minimally invasive surgery in HGSL remains unknown. We propose a hybrid technique combining PS with MTFD for lytic HGSL. Methods This study included 25 patients with adult lytic HGSL (Meyerding grade III and IV) operated using a hybrid technique from 2012 to 2015. Data were compared with retrospective data on conventional open reduction (n=23) operated from 2000 to 2015. The minimum follow-up was 5 years. Clinical outcomes were assessed using the Visual Analog Scale (VAS) score and modified Oswestry Disability Index (m-ODI). The spinopelvic and perioperative parameters were recorded. The inter-body fusion and adjacent segment degeneration (ASD) were assessed on radiographs at the final follow-up. Results The average age in the MTFD and open groups was 45.84±12.70 years (nine males and 16 females) and 49.26±13.33 years (eight males and 15 females), respectively. Further, 22 and three patients in the MTFD group and 19 and four in the open group had grade III and IV listhesis, respectively. The MTFD group demonstrated less operative time, blood loss, and hospital stays than the open group. Significant improvements were observed in VAS and m-ODI in subsequent follow-ups in both groups. The MTFD group fared better at 3 months but outcomes were comparable at the final follow-up. Both techniques were equally effective in restoring spinopelvic parameters. The incidence of ASD is comparable. Conclusions The technique was proven effective in reducing HGSL. The long-term clinical and radiological outcomes were favorable and comparable with the conventional approach

Molecular Biology of Head & Neck Cancer: Risks and Pathways
Patients present with a differential baseline risk of cancer based on normal and expected variations in genes associated with cancer. The baseline risk of developing cancer is acted on throughout life as the genome of different cells interacts with the environment in the form of exposures (eg, toxins, infections). As genetic damage is incurred throughout a lifetime (directly to DNA sequences or to the epigenome), events are set in motion to progressively disrupt normal cellular pathways toward tumorigenesis. This article attempts to characterize broad categories of genetic aberrations and pathways in a manner that might be useful for the clinician to understand the risk of developing cancer, the pathways that are disrupted, and the potential for molecular-based diagnostics
Regular Antenatal Care Visits Predict Good Knowledge Among Post-natal Mothers Regarding Entitlements of Health Programs in Western India
Janani-Shishu Suraksha Karyakram (JSSK) and Janani Suraksha Yojana (JSY) were launched with the objective of increasing institutional deliveries. But, its knowledge among the post-natal mothers is not known. This research evaluated the knowledge of two national health programs among post-natal mothers and found out the predictors of good knowledge about the entitlements of these programs. A cross-sectional study was conducted on a sample of consecutively recruited 339 post-natal mothers who had delivered in a tertiary care hospital of western India. Data were collected from November 2016 to February 2017 by interview method using a questionnaire with questions about knowledge regarding the entitlements of JSSK and JSY. Multivariable analysis was carried out for predictors of good knowledge. Among the 339 post-natal mothers, 30% had a good knowledge regarding JSSK. Only 24% had heard about JSSK; 54% knew regarding free transport to the place of delivery; only 22% and 13%, respectively knew about free inter-facility transport in case of complications for pregnant women and sick infants, while 96% knew regarding free drop-back facility. Only one-fourth of the mothers knew regarding monetary benefit under JSY, while 28% of them had actually received the benefit. The number of antenatal care visits, having an occupation and belonging to Hindu religion significantly predicts good knowledge among postnatal mothers regarding JSSK. Knowledge among the post-natal mothers regarding the entitlements of JSSK and JSY is less while comparing with published literature and needs improvement. Regular ante-natal care (ANC) visits might improve their knowledge of these programs. There is a need to create awareness among hospital staff for the provision of reimbursement of costs incurred by post-natal mothers. There is also a need to carry out demand generation activities among mothers regarding the entitlements of JSSK and JSY
