Management of lateral end clavicle fractures-using lateral clavicle locking plate: a prospective study

Background: Lateral end clavicle fractures are one of the common upper limb fractures. They constitute 21–28% of all clavicle fractures. Of these 10–52% is displaced fractures. The management of fractures of lateral end clavicle remains debated and challenging. The objectivbe of this study is to evaluate the functional outcome following surgical treatment of unstable/displaced (Neer type II lateral clavicle fractures, and acromio-clavicular joint dislocations Rockwood grade III to V) lateral end clavicle fractures using lateral clavicle locking plate.Methods: It is a prospective study conducted in the orthopaedics department of GSL Medical College and General Hospital for a period of 3 years (April 2016 to March 2019) among a total of 60 patients.Results: About 23 (38.3%) belonged to 41–50 years age group, followed by 16 (26.7%) to 31–40 years age group and 13 (21.7%) to >51 years age group and 8 (13.3%) to 18–30 years age group. The time from trauma to surgery ranged from 0-15 days with a mean of 5 days and the mean operating time was 41 minutes ranging between 23-70 minutes. Mean duration to union was 13.33±2.126 weeks and the mean Constant Murley score was 88.56. Functional outcome at 6 months follow up was excellent in 8 (13.3%), good in 37 (61.7%), fair in 13 (21.7%) and poor in 2 (3.3%) patients.Conclusions: Although there is no consensus as to a “gold standard” fixation method for unstable distal clavicle fractures, satisfactory outcomes could be obtained using the lateral clavicle locking plate resulting in sufficient stabilization and good functional outcome

A bibliography of parasites and diseases of marine and freshwater fishes of India

With the increasing demand for fish as human food, aquaculture both in freshwater and salt water is rapidly developing over the world. In the developing countries, fishes are being raised as food. In many countries fish farming is a very important economic activity. The most recent branch, mariculture, has shown advances in raising fishes in brackish, estuarine and bay waters, in which marine, anadromous and catadromous fishes have successfully been grown and maintained

Action of sulphanilamide derivatives in experimental streptococcal and pneumococcal infections in mice. Part II

The results of testing thirty-six derivatives of sulphanilamide of various groups in experimental ß-haemolytic streptococcal and pneumococcal (type 1) infections in mice have been presented. The therapeutic activity of the derivatives with substituents in the (N)-amino radical of sulphanilamide or sulphanilamido derivatives, appears to depend upon whether or not they can yieldin vivo the latter compounds in adequate concentrations. In the attempts to discover highly active compounds, the study of the derivatives of sulphanilamide with suitable heterocyclic rings substituted at the sulphonamide radical have been made. Of the many such compounds so far tested, the sulphanilamidothiazole derivatives, 13 and 33, and the sulphanilamidopyrimidine derivative, 57, have been found to be of outstanding value. The significant relationship existing between the chemical constitution and chemotherapeutic action has been pointed out

Stacking angle dependent multiple excitonic resonances in bilayer tungsten diselenide

We report on multiple excitonic resonances in bilayer tungsten diselenide (BL-WSe2) stacked at different angles and demonstrate the use of the stacking angle to control the occurrence of these excitations. BL-WSe2 with different stacking angles were fabricated by stacking chemical vapour deposited monolayers and analysed using photoluminescence measurements in the temperature range 300–100 K. At reduced temperatures, several excitonic features were observed and the occurrences of these exitonic resonances were found to be stacking angle dependent. Our results indicate that by controlling the stacking angle, it is possible to excite or quench higher order excitations to tune the excitonic flux in optoelectronic devices. We attribute the presence/absence of multiple higher order excitons to the strength of interlayer coupling and doping effect from SiO2/Si substrate. Understanding interlayer excitations will help in engineering excitonic devices and give an insight into the physics of many-body dynamics
