Authors | : | Sharad Saxena || Aditya Chaudhary || Nikhil Bansal || Medha Gupta |
Abstract: Cysticercosis caused by larval stage of the tapeworm Taenia solium, is a major public health problem.1 Humans are only definitive host of T. solium harbouring the adult tapeworm in the intestine (referred to as, taeniasis). Both humans and pigs act as intermediate hosts and harbour T. solium larvae in different internal organs (referred to as, cysticercosis) including the brain (referred to as, neurocysticercosis - NCC).2 Neurocysticercosis is central nervous system (CNS) infection with T. Solium,it isidentified as the single most common cause of community acquired active epilepsy cases in the developing world including India. It is also becoming more common in the developed world because of increased migration of people with the disease or Taenia solium carriers and frequent travel to the endemic countries.

Country | : | India |
Authors | : | Dr. T.M. Jose || Dr. Girish Kumar K || Dr,. Anil George Paul |
Abstract: Treatment of club foot is still a clinical challenge. The literature on clubfoot as a general rule, that of unvarying success. The increased failure rates among conservative management has lead to various surgical interventions. A recent study of clubfoot surgeries have come up with a high proportion of unsatisfactory results. The work of Illizarov showed encouraging results without the dreaded complication of infections. He believed that controlled mechanical stress lead to regeneration of soft tissues including skin, muscle, tendon, nerve.

Abstract: Objective: To share our surgical experience in treating inverted papilloma. Study Design: Retrospective study Setting: Tertiary referral Hospital Results: In our series majority of cases were done by external approach by lateral rhinotomy (50/70), the endoscopic assistance is required to ensure complete removal of the tumour to reduce the recurrence rates. A significant number (20/70) were done by exclusive transnasal endoscopic approach when the tumour is confined to middle meatus, maxillarysinus, frontal recess, ethmoid and sphenoid sinus. Overall recurrence rate was 22%

Abstract: Hydatid cyst (HC) is a zoonotic infection of the human caused by Echinococcus granulosus. The disease poses an important public health problem in many areas of the World. HC may develop in almost any part of the body. Most hydatid cysts occur in the liver (59-75%), followed in frequency by the lung (27%). Involvement of the kidney (3%), bone (1-4%) and brain (1-2%) is rare. In this article, the imaging findings of the hydatid cysts in different localization are reviewed. Findings in brain, lung, heart, liver, kidney, intra- and retro-peritoneum, spleen, pancreas, ovary, soft tissue and spine are discussed.

Country | : | India |
Authors | : | Dr. Sampath Priya Kumar Talamala || Dr. Purnima Gummadi || Dr. Ganga Bhavani Vatti. |
Abstract: The venereal diseases and their Clinical presentations were well known, hence we made an attempt to study the various Non Venereal male genital dermatoses in a Tertiary care center for a period of one year. With an aim to establish their etiology and review of literature. All the male patients who attended the DVL OP of Government General Hospital, Vijayawada, for a period of one year from October 2014 to September 2015 with genital complaints were examined and screened to rule out any Venereal diseases and HIV/AIDS. Only the Non Venereal genital deramtoses were identified and further investigated along with biopsy to establish the diagnosis and the results were analysed.

Title | : | A Comparative Study of the Efficacy of Ormeloxifene and Norethisterone in Perimenopausal Dysfunctional Uterine Bleeding and Perimenopausal Symptoms. |
Country | : | |
Authors | : | Dr Pia Muriel Cardoso |
Abstract: Dysfunctional Uterine Bleeding (DUB) is the most common cause of abnormal uterine bleeding, accounting for 20% of gynaecology office visits (1). Regarding the medical management of DUB, there is ambiguity in an evidence based approach, marked variation in current practice and continuing uncertainty regarding the most appropriate therapy. There are very few studies comparing the effect of ormeloxifene and progesterone in DUB. The objective of the study was to compare the efficacy and safety of these two drugs, Norethisterone and Ormeloxifene, a selective estrogen receptor modulator, which is rapidly emerging as a safe and effective agent for dysfunctional uterine bleeding..

Title | : | Radiographic Assessment of Quality of Root canal Treatment Carried Out by General Dental Practitioners at the University of Port Harcourt Teaching Hospital |
Country | : | Nigeria |
Authors | : | Arigbede AO || Umanah AU || Igwedibia PC |
Abstract: Literature review suggests that the quality of root canal treatments (RCTs) performed by general dental practitioners often do not meet acceptable standard. This is of concern because the bulk of endodontic procedures are carried out by this group of dentists. This survey was undertaken to evaluate the radiographic technical quality of RCT done by general dental practitioners at out centre. A one-year review of the records of adult patients whose RCTs were done by general practitioners was done. The list of the patients involved was compiled from the departmental records, following which their folders were retrieved from the Records Department. Socio demographic variables of the patients and the root-filled teeth were recorded. Post obturation periapical radiograph of the patients were also analyzed for adequacy of length, density and tapering as described by Román-Richon et al.and coronal restoration as described by Kalender et al.

Abstract: "Hangman´s fracture" and Traumatic Spondylolisthesis of Axis( ATS )are terms described for bilateral pars fracture of C2.Traumatic spondylolisthesis of the axis (TSA) was first described by Haughton in 1866(1). Wood-Jones described in 1913, in cases of judicial hanging.(2) In 1964, Garber(3) described C2 pedicle fractures with the forward dislocation of the C2 body in patients who were victims of motor vehicle accidents, what was denominated "Axis Traumatic Spondylolisthesis". In 1965, Schneider et al (4) coined the term "Hangman´s Fracture".

Abstract: All-ceramic zirconia restorations veneered with porcelain materials, show high strength, excellent bio compatibility and good estetic. Some mechanical damages happen during the functional masticatory load, and chipping is most common. There are several reasons for this complication, and they are lower bond strength, mismatch of the KTE (coefficient for thermal expansion) of both materials, premature contacts, and lower flexure strength of the veneering porcelain. The aim of the study is to evaluate and analyze the flexure strength of three veneering ceramics for all-ceramic restoration. Veneering porcelain for metal-ceramic restorations is used as control group. Results for flexure strength of the veneering ceramics showed that all-ceramic veneering materials have similar strength values, but they are still lower than strength value for control group of metal-ceramic material. There must be effort to improve strength properties of the veneering ceramics for zirconium pointed towards increasing of the mechanical strength and thermal coefficients adjutancy
