The Economics of Suicide

On April 8th 1994 Kurt Cobain, the lead singer of Nirvana, was found dead in his Seattle home of an apparent shotgun wound to the head and with three times the lethal amount of heroin in his system. A note lay at the scene. The verdict was suicide. Others are sceptical.’ (from www.deathofkurtcobain.com) In the pall of gloom surrounding Michael Jackson’s recent death when we read this extract from a site dedicated to Kurt Cobain, a number of questions struck us as being interesting. Why do famous celebrities commit suicide? Could the reasons be monetary, social or some other phenomenon? Why would such renowned personalities give up an apparent life of luxury? In furthering our understanding of these issues it strikes us as pertinent to ask whether we can ever view suicide from the perspective of an economist. Can we assess human behaviour pertaining to suicide using the ration al science of economics or are we treading on unknown territory in psychiatry instead? Consider a quote by the famous economist Gary Becker from his book The Economic Approach to Human Behaviour

Gradual distraction for treatment of severe knee flexion contractures using the Ilizarov’s apparatus

Background: Knee flexion contractures result in a significant amount of functional disability due to reduced mobility and limb length discrepancy. Treatment options include non-surgical methods like serial casting, dynamic splinting and traction or surgical methods like osteotomies and soft tissue procedures. External fixation has emerged as a highly successful means of achieving controlled gradual correction of joint contractures with low rates of complications including recurrence. The aim of this study is to evaluate the functional outcome in terms of residual deformity and change in ambulatory status following correction using the Ilizarov’s apparatus.Methods: 12 patients with knee flexion contractures ranging from 20°-70° underwent correction using the Ilizarov’s external fixator (IEF). The use of simple mathematic formulae enabled us to calculate and estimate the rate and duration of distraction. End results were assessed at one year by the residual contracture as: Excellent: 0-5°, Good: 6-15°, Fair: 16-30° and Poor: >30°.Results: The functional assessment was graded as excellent in 7, good in 4 and fair in 1 out of 12 patients. All patients were independent ambulators and only 1 out of 12 patients required an additional orthosis for maintenance of the correction.Conclusions: The IEF is a safe and precise modality even for the most complex contractures of the knee. Accurate placement of the hinges along the center of rotation of the knee avoids undue subluxation of the tibia during correction. In order to ensure a low rate of complications, it is imperative to have a detailed pre-operative plan and all principles of fixation should be meticulously adhered to.

Incidence of patella baja following patellar eversion in total knee arthroplasty

Background: Patella baja is a rare complication of total knee arthroplasty (TKA) leading to decreased mechanical advantage of the extensor mechanism, decreased knee range of motion, anterior knee pain and increased wear of the tibial and patellar polyethylene. There exists a lack of evidence on whether patellar eversion leads to shortening of the patellar tendon. The present study aims to determine if eversion of patella during TKA leads to patella baja.Methods: Between August 2014 and August 2016, 55 knees undergoing primary TKA with a standard medial parapatellar arthrotomy and eversion of patella were included in this two point cross sectional study. Preoperative X-rays were taken to assess the length of the patellar tendon and Insall Salvati ratio (ISR). Postoperatively the Blackburne Peel Index (BPI), ISR and patellar tendon lengths were assessed on lateral X-rays to look for any incidence of patella baja.Results: The postoperative change in the length of the patellar tendon was unpredictable; though most of them decreased. The pre and post op difference in the length of patellar tendon was statistically significant in females (4.43±0.20 cm vs. 4.35±0.24 cm; p value-0.005). Significant decrease in length of patellar tendon was seen in patients aged 66-70 years (p= 0.024) and patients with BMI >30 kg/m2. No case of true patella baja was found postoperatively. No significant correlation could be established between ISR and age, sex or BMI of the patients.Conclusions: The different risk factors for post TKA shortening of patellar tendon include female gender and higher BMI (>30 Kg/m²). However eversion of patella during TKA may not lead to an increased incidence of true patella baja

Management of infected non-union of lower limb long bone fractures using ilizarov technique: a study of outcomes

Background: Nonunion of long bone fractures is a common condition treated by an orthopaedic surgeon. Many nonunions can be treated effectively by internal fixation with or without bone grafting but, an infected nonunion can prove to be a tough challenge. The Ilizarov method is effective in managing infected nonunion of long bones. This study aims to assess the outcome of management of infected nonunions of long bones of lower limb with Ilizarov Ring fixator using bone and functional results as per Association for the Study and Application of Methods of Ilizarov (ASAMI) Scoring System.Methods: We retrospectively analysed 18 patients (16 Male: 2 Female; Mean age 43.2 years) managed with Ilizarov technique for an infected tibial or femoral nonunion between 01 January 2013 and 31 December 2014. They were followed up for an average of 25.4 months after removal of fixator. They were assessed for functional and Bone (radiological) outcomes using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria.Results: 17 limbs were salvaged and union could be achieved. One limb required amputation due to severe persistent intractable infection. None required any additional skeletal stabilisation after removal of fixator frame except casting in a few patients for a period of 6 weeks. Mean time to union was 211.83 days (range 136 - 320days/median 184) or 7.01 months. As per the ASAMI score, Bone results were excellent in 10, good in 5, fair in 2 and poor in 1. Functionally 7 were graded as excellent, 6 as good, 3 as fair and 1 as poor and 1 patient underwent amputation.Conclusions: The Ilizarov’s method remains one of the most versatile and successful means of achieving bone healing in infected nonunions of long bones of lower limbs with additional benefits of correcting bone defects, deformities and limb length inequalities.

DESIGN AND MANUFACTURING OF CORN SHELLING MACHINE

India depends on agriculture to drive the engine of its economic development. Corn has been cast in the lead role of this ongoing storyline of agriculture success, and without corn, the India farm sector would be just a shell of what is has now become. Corn is grown on small scale, corn’s price is growing day by day it has almost became the double of the price of the maize. Corn Sheller is a major problem of corn production, especially in India. The performance of the machine will be evaluated in terms of shelling efficiency, materialefficiency, etc. The project describes about the design of various components of corn shelling machine. Overall, this project involves process like design, fabrication and assembling of different components, etc. This project describes the design and development of motorized corn shelling machine
