<p class="abstract"><strong>Background:</strong> Proximal humeral fractures account for 5% of all fractures. Observed frequently in older osteoporotic patients but found in young patients with high-energy trauma.About 80% of these fractures are undisplaced or minimally displaced. Non-operative method requiring immobilization of shoulder often leads to a stiff shoulder, whereas surgical procedures such as plating need excessive soft tissue dissection. It was overcome in this study by less soft tissue dissection by use of external fixator application and early mobilization.</p><p class="abstract"><strong>Methods:</strong> Total of 18 patients mean age 40.5 years, predominantly male (16/18) treated with external fixator - JESS (Joshi’s external immobilization system) for Neer’s two, three and four part proximal humeral fractures. Vehicular accidents were the most common mode of injury followed by fall. There were 8 cases each of Neer's two and three part fractures. Shoulder mobilization started within a week as postoperativelyas pain allowed. Patients followed up at 3, 6, 12 and 18 weeks for pain, function, range of motion and anatomy with check X-ray. After radiological union at 8-10 weeks JESS was removed. Cases were evaluated for functional result by constant scoring system.<strong></strong></p><p class="abstract"><strong>Results:</strong> Average score on constant scoring system was 72 after a mean follow-up of 6 months. All fractures united in mean duration of 9.33 weeks. The complications included shoulder stiffness in one case and pin tract infection in two cases.</p><strong>Conclusions:</strong> Early shoulder mobilization a prerequisite for good results can be achieved without compromising fracture union. Less soft tissue dissection required and significant cost effective.
Introduction The definitive diagnosis of neurocysticercosis continues to be challenging. We evaluate the role of newer magnetic resonance imaging techniques including constructive interference in steady state, susceptibility-weighted imaging, arterial spin labelling and magnetic resonance spectroscopy in the diagnosis of neurocysticercosis. Aims and objectives To study the utility of newer magnetic resonance imaging sequences in the diagnosis of neurocysticercosis. Patients and methods Eighty-five consecutive patients with neurocysticercosis attending a tertiary care hospital and teaching centre in northern India were included in the study. The diagnosis of neurocysticercosis was made by the Del Brutto criteria. All patients received treatment according to standard guidelines and were followed at 3-month intervals. The following magnetic resonance sequences were performed at baseline: T1 and T2-weighted axial sequences; T2 fluid-attenuated inversion recovery axial sequences; diffusion-weighted imaging; susceptibility-weighted imaging; pre and post-contrast T1-weighted imaging; heavily T2-weighted thin sections (constructive interference in steady state); arterial spin labelling ( n = 19); and magnetic resonance spectroscopy ( n = 24). Results The mean (±SD) age was 29.4 ± 12.9 years and 76.5% were men. Seizures were the commonest symptom (89.4%) followed by headache (24.3%), encephalitis (9.4%) and raised intracranial pressure (9.4%). Scolex could be visualised in 43.7%, 55.5% and 61.2% of neurocysticercosis patients using conventional, susceptibility-weighted angiography and constructive interference in steady state imaging sequences, respectively. Susceptibility-weighted angiography and constructive interference in steady state images resulted in significantly higher ( P < 0.01) visualisation of scolex compared to conventional sequences. Conclusion Newer magnetic resonance imaging modalities have a lot of promise for improving the radiological diagnosis of neurocysticercosis.
The work was undertaken to investigate the phytotoxic potential of essential oil from Melaleuca leucadendra against three weed species, viz., Echinochloa crus-galli, Cyperus rotundus and Leptochloa chinensis. It was observed that volatile oil (0.25-1.5 mg ml-1) of Melaleuca retarded the germination and growth of all the test weeds in a dose-response bioassay conducted under laboratory conditions. Generally, both root and shoot length showed an inhibitory effect in a concentration dependent manner and the maximum effect was observed in C. rotundus, followed by E. crus-galli and L. chinensis. The Melaleuca oil not only affected the germination and seedling growth of the test weeds, but also inhibited the chlorophyll content and dry weight. At the highest dose of Melaleuca oil treatment (1.5 mg ml-1), the chlorophyll content declined by nearly 50% in E. crus-galli and 90% in L. chinensis over the control. Thus, it is concluded that volatile oil possesses phytotoxic potential towards other plants and could be further explored for weed management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
