An epidemiological study of low back pain in a tertiary care hospital of Jammu, Jammu and Kashmir, India

Background: Backache is a national, personal and clinical problem. It is experienced by most of the population at some time and is a drain on the nation’s resources. Personally, it is distressing because it can remain a major unresolved dilemma and clinically it poses challenges in diagnosis and treatment.Methods: The present cross sectional study was conducted among 200 patients presenting with chronic low back pain, in the OPD of Post Graduate Department of Orthopaedics, Govt. Medical College, Jammu over a period of one year from November 2006 to October 2007.Results: The average age of patients was 38.39 years with slight male predominance. Majority of the patients were non-sedentary workers. In majority of the cases (58%), duration of low backache was from 3 months to 1 year with the average of 25.8 months (2.158 years). The commonest mode of presentation was low back pain with radiation to lower limbs. Seasonal variation in the intensity of pain was observed in 50% of the cases. Tenderness of the spine was the commonest physical sign. Disc degenerative disease was found to be commonest cause of low backache, being present in 72% of the cases.Conclusions: Low back pain is common in 3rd and 4th decade of life. The commonest mode of presentation was low back pain with radiation to lower limbs. Disc degenerative disease was found to be commonest cause of low backache, being present in 72% of the cases

Pattern of hand injuries reported in a tertiary care setting of North India

Background: Hand injuries are very common in this industrialized world. Significant number of patients report every day to the emergency department with various patterns of hand injuries. It is important to understand these patterns in order to plan proper management and develop safety protocols aimed at preventing these injuries.Methods: The present cross sectional study was conducted among 150 patients presenting with Open hand injuries, in the OPD and emergency of Post Graduate Department of Orthopaedics, Government Medical College, Jammu over a period of one year from January 2010 to December 2010.Results: Out of 150 cases 131(87.33%) were males and 19 (12.67%) were females. The commonest age group affected was 21-30 years (34%) followed by 11-20 years (23%). Maximum injuries 90 (60%) occurred in the time interval from 4 pm to midnight. Majority of patients 67 (45%) sustained injury while at work.  Occupation-wise 37 (25%) patients were unskilled workers, mainly laborers, 35 (23%) were farmers, while the remainder belonged to various other professions. In this series machine injuries, assault and road traffic accidents accounted for most injuries, representing 61 (41%), 25 (17%) and 16 (11%) patients respectively. Traumatic amputation (30%) was the most common injury. The index (21%) and middle (21%) fingers were involved more commonly. Tendon injuries (31%) were more frequent than compound fractures (23%).  Conclusions: Hand trauma predominantly affects young males who have occupational exposure to different machines. A proper understanding of the pattern of injury will help in better management

Study of efficacy of compression suture in the surgical management of atonic PPH

Background: Study was conducted to analysis efficacy of compression suture in the surgical management of Atonic PPH. It’s prospectively carried out with 60 cases required compression suture in managing Atonic PPH. Atonic uterus is preventable cause of maternal mortality and morbidity constituting 80% PPH cases.Methods: Prospective study carried out at tertiary care center for studying efficacy of compression suture in the surgical management of atonic PPH for one year, started after approval from ethical committee.Results: Compression suture is effective in managing atonic PPH. out of 60 cases, 4 patient's required obstetric hysterectomy as a last resort to control Atonic PPH. Uterus was conserved in 93.3% of cases.Conclusions: Development of compression suture technique has proved to be effective in the control of massive Atonic PPH not responding to medical management is an alternative to hysterectomy when timely applied. It proves to be valuable addition for surgical treatment of PPH and for saving uteri after medical management of PPH failed. Authors can adopt compression suture as a mid-step before resorting to uterine devascularisation or hysterectomy when medical line of management fails. Resident doctors in teaching institutes must be well trained in this technique

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV

The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.
