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

Garnet mineral chemistry as a provenance indicator for the modern beach sediments of north-eastern Andhra Pradesh, east coast of India

917-924The provenance of garnets from coastal sediments between the Nagavali and Vamsadhara river mouths, east coast of India were studied using garnet molecular proportions. This mineral chemical electron micro probe analytical data have been correlated with published garnet chemistry from various litho units of the eastern ghats granulite belt to understand provenance. The present study reveals that the garnets with molecular proportions of almandine (Alm. 50-56%), pyrope (Py. 33-43%) and traces of grossular (Gr. 5%) were derived from charnockite suite of rocks. The major portion (83%) of the studied garnets is derived from khondalite (metapelitic) suite of rocks susceptible for physical weathering due to large areal exposure and minor proportion (17%) is derived from charnockite suite of rocks which due to less coverage in drainage basis is not susceptible for mechanical weathering

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

Vibrational Hamiltonian of Carbonyl Sulphide and Hydrogen Cyanide

This study thoroughly investigates the vibrational frequencies of carbonyl sulphide (12C16O32S) and hydrogen cyanide (HCN) up to the fifth harmonic level. It offers comprehensive insights into vibrational modes by using the Hamiltonian operator formalism and concentrating on invariant operators and algebraic parameters with a one-dimensional Lie algebraic method. The findings are significant for atmospheric chemistry, spectroscopy, and quantum chemistry, contributing to a deeper understanding of molecular dynamics. This research sets the groundwork for future studies in comparable compounds and applications
