Pulmonary Edema following Phenylephrine Intranasal Spray Administration during the Induction of General Anesthesia in a Child

Topical phenylephrine, an agent used to facilitate nasotracheal intubation and prevent nasal mucosal bleeding, can cause severe hypertension in some patients, secondary to its stimulation of alpha-adrenergic receptors. Moreover, a high incidence of pulmonary edema is found in patients whose phenylephrine administration is followed by treatment with beta-blocking agents. We report a case of acute pulmonary edema in a pediatric patient who developed severe hypertension after the inadvertent administration of a large dose of topical nasal phenylephrine, followed by beta-adrenergic antagonists (esmolol)

BIBLIOMETRIC DIMENSION OF INNOVATION COMMUNICATION PRODUCTIVITY OF TATA INSTITUTE OF SOCIAL SCIENCES

ABSTRACT Bibliometric analysis of 663 papers published by the social scientists of Tata Institute of Social Sciences during 1990-2000 in diverse domains in the social sciences were analysed for authorship pattern and collaboration. The results indicate that the collaboration co-efficient of the 613 single-authored papers is 92.46 percent, followed by 6.33 percent (42 papers) two authored papers. Maximum collaboration coefficient (0.13) was found during 1996-1997

Interventional radiography in management of high-flow arteriovenous malformation of maxilla: report of a case

Arteriovenous malformations are extremely rare conditions in that can result from abnormalities in the structure of blood vessels, which may be potentially fatal. A 30-year-old female patient visited our hospital with a complaint of swelling on the right maxillary posterior gingiva along with the large port-wine stain on right side of face. On clinical examination, the swelling was compressible and pulsatile. Radiographic examination revealed a lytic lesion of maxilla. Diagnostic angiography revealed a high-flow arteriovenous malformation of maxilla which was treated by selective transarterial embolization of maxillary artery using polyvinyl alcohol particles

Delayed diagnosis of oral squamous cell carcinoma: a case series

<p>Abstract</p> <p>Introduction</p> <p>In malign neoplasms, oral cancer is one of the important causes of mortality and morbidity. Squamous cell carcinoma is the most common form of oral cancers in adults and is related to risk factors such as smoking and alcohol consumption.</p> <p>Case presentation</p> <p>In this article, we present three case reports of oral squamous cell carcinomas with delayed diagnosis. The first patient was a 52-year-old Turkish man, the second patient was a 61-year-old Turkish man and the third patient was a 60-year-old Turkish woman. All were referred to the Ankara University Faculty of Dentistry with pain, swelling and various complaints in their jaws.</p> <p>Conclusion</p> <p>Early diagnosis is of vital importance for the prognosis of the patients with oral squamous cell carcinomas. For this reason, dentists play a crucial role in the early detection and prevention of oral cancers.</p

Cancerization of cutaneous flap reconstruction for oral squamous cell carcinoma: report of three cases studied with the mtDNA D-loop sequence analysis

International audienceAims: tissue defects, resulting from surgical resection of oral squamous cell carcinoma (OSCC), are routinely reconstructed with skin graft. OSCC arising from the grafted skin have been described, however, it is still unclear whether primary and second tumours have a common clonal origin. By screening mitochondrial DNA D-loop region (mtDNA), we evaluated the clonal relationship between the primary OSCC and the second neoplastic features appearing in the skin graft in three patients. Methods and Results: in all the three cases, the neoplastic lesions arising in the skin graft showed a clonal relationship with the previous OSCC and, on the basis of the results obtained with the mtDNA analysis, could be considered a recurrence of the primary OSCC rather than a second primary OSCC. Conclusions: Starting from a field of genetically altered cells of the oral mucosa, the spreading of the clonal cell population to the cutaneous flap might be stimulated by cytokines produced by the grafted skin. More studies are needed to evaluate the molecular relationship between primary and second OSCC to identify patients at higher risk of developing a second tumour of the skin graft
