An In Vivo 24-Month Study to Compare Crestal Bone Loss and Pocket Depth of Platform-Switched Implants Placed in Maxillary Anterior and Mandibular Posterior Regions.

Purpose: To analyze and compare crestal bone loss and pocket depth around platform-switched implants placed at two intraoral locations.

Materials And Methods: Eighty platform-switched implants, 40 in the maxillary anterior region (group - ANT) and 40 in the mandibular posterior region (group - POST), were placed in healthy men aged between 25 and 45 years, and restored following two-stage surgical and progressive loading protocols. Digital radiographs for crestal bone level assessment and pocket depths on facial, mesial, distal, and palatal/lingual sites around the implant were recorded at definitive restoration cementation (baseline) and 6-month follow-up.

Use of electroconvulsive therapy for Asian patients with schizophrenia (2001-2009): Trends and correlates.

Aims: Little is known about electroconvulsive therapy (ECT) use in Asian inpatients with schizophrenia. This study examined trends of ECT use for schizophrenia patients in Asia between 2001 and 2009 and its independent demographic and clinical correlates.

Methods: Data on 6761 hospitalized schizophrenia patients (2001 = 2399, 2004 = 2136, and 2009 = 2226) in nine Asian countries and territories were collected by either chart review or interviews during a 1-month period.

Multi-drug resistant tuberculosis: an iatrogenic problem.

The occurrence of resistance to drugs used to treat tuberculosis (TB), and particularly multi-drug resistant TB (MDR-TB) defined as resistance to at least rifampicin and isoniazid, has become a significant public health dilemma in a number of countries and an obstacle to effective global TB control. HIV-associated MDR-TB understanding is vital in providing strategies for treatment of HIV and drug-resistant TB. Better understanding on the basis of drug action and resistance is a key to development of diagnostic strategies, novel drugs, and treatment programs, and to find an approach to study the pathogenicity of drug resistant strains.

Cognitive psychiatry in India.

Cognitive deficits have been shown to exist in various psychiatric disorders. Though most Indian studies pertaining to cognition have been replication studies, well designed original studies have also been conducted. This article traces the evolution of cognitive psychiatry in India.
