A study of mediastinal tumours in a tertiary care centre: a retrospective study

Background: Recent advances in diagnostic and surgical techniques have brought major changes in the clinical presentation, diagnosis and the surgical management of mediastinal masses. Indian literature in this scenario is deficient, which our retrospective descriptive study aims to address.Methods: Details of patients operated for mediastinal masses from January 2007 November 2013 in two units at NIMS were collected. Clinical presentation, symptomatology, radiological/pathological findings, surgical approaches, intraoperative/immediate/intermediate post-operative results were evaluated and analysed.Results: Of the 75 patients, (48 males, range 10 years to 65 years) 2 deaths were due to complications following exacerbation of myasthenia gravis, and two patients died due to post-operative bleeding. Thymicneoplasms were the most common, followed by neurogenic tumours. Most common presentation was myasthenia gravis, followed by nonspecific back pain. 4% of patients had symptoms due to local compressive effects. Tumour was in the anterior mediastinum, middle and posterior mediastinum in 53, 16 and 6 cases respectively. Surgery done with a curative intent was through sternotomy (59), posterolateral thoracotomy (14), and combined sternotomy and cervical route (2). Residual tumour was present in 5 cases due to nerve involvement. Follow up was 98% (2 months to 6 years). 3 patients died of unrelated causes and one developed multiple lung metastases. 2 patients with neurogenic tumours developed recurrence.Conclusions: Inadequately optimized myasthenia patients and superior vena cava obstruction are poor prognostic factors. Complete excision may not be possible in neurogenic extension to spine even with concomitant neurosurgery. Neurological infiltration has a poorer prognosis

Taurodontism with oligodontia in a young female patient: A case report with a brief literature review

Human dentition is affected by a wide variety of abnormalities, which include variation in the number, morphology and eruption sequence. Absence of tooth development manifests as anodontia, hypodontia, and oligodontia. Taurodontism is a developmental anomaly affecting the teeth leading to minimal or no constriction cement enamel junction level manifesting as long pulp spaces and also the trunk of the roots is displaced toward apex giving a rectangular shape to the involved tooth. Its commonly seen in permanent teeth is common and rarely in the deciduous dentition. Oligodontia is an uncommon genetic condition representing the congenital missing of six teeth or more in primary or permanent dentitions. This case report describes concomitant occurrence of tooth agenesis and taurodontism in a young Saudi girl and a brief review regarding the etiology, clinical features, and therapeutic aspects of have been mentioned

The salinity ranges from 27.9 to 40.9 ‰, the temperature range is from 23.6o to 32o C, the dissolved oxygen content ranges from 6.4 to 8.2 ml/L and the substrate of the lake is characterized by sand, silty sand, muddy sand, clayey sand and sandy clay. Sand dominates the other types of substrate towards the mouth of the channel at Arakudha Village. Organic matter content of the sediment varies from 0.31 to 2.0 %. Fifteen agglutinated foraminiferal species - <i style="mso-bidi-font-style: normal">Ammobaculites agglutinans, A. directus, A. exiguus, Ammotium fragile, Gaudryina exilis, Haplophragmoides canariense, Jadammina macrescens,<span style="font-size:10.0pt;mso-bidi-font-size: 11.0pt;font-family:" times="" new="" roman";mso-fareast-font-family:"times="" roman";="" mso-bidi-font-family:mangal;mso-ansi-language:en-gb;mso-fareast-language:en-us;="" mso-bidi-language:hi"="" lang="EN-GB"> Miliammina fusca, M. fusca var., Reophax dentaliniformis, Textularia earlandi, Tiphotrocha kellettae, Trochammina advena, T. hadai and T. ochracea of which <i style="mso-bidi-font-style: normal">Miliammina fusca, M. fusca var. and Ammobaculites exiguus are of abundant occurrence tolerating relatively higher salinity and temperature. </span

Recent foraminifera from nearshore shelf, south of Visakhapatnam, east coast of India

71-73Forty two species of Foraminifera are recognised from the sediments of inshore waters (3-10 m depth). Both living and dead individuals of Foraminifera have been studied. The assemblage is devoid of agglutinated forms

Living foraminifera associated with algae from rock pools near Visakhapatnam, East Coast of India

212-219Forty four species of foraminifera are found on algae in rock pools. Standing crop is higher on the filamentous and smooth thalloid algae than on non-filamentous and hard algal surfaces. Pararotalia nipponica, Cymbaloporetta bradyi, Rosalina floridana, R. globularis and Vertebralina striata of the faunal assemblage are highly successful in adapting to algal surfaces. These species are considered to be primarily endemic to the environment

Prediction of Effective Mobile Wireless Network Data Profiling Using Data Mining Approaches

Abstract Mobile network analysis has a huge potential that provide insight into the relational dynamics of individuals. Machine learning and data mining techniques provide the behavior patterns of the mobile network data. The data transfer during all the days has produced good results in transfer of data starting from Day 1 to Day 22. Hierarch ical clustering of the datasets for all the 1634 data examples in the mobile t raffic dataset. Co mplete linkage dendrogram has been produced between 0 and 4.64. Two clusters have been produced from the present wireless mobile t raffic datasets
