Revalidating Pfirrmann's Magnetic Resonance Image-Based Grading of Lumbar Nerve Root Compromise by Calculating Reliability among Orthopaedic Residents.

Background: Intervertebral disc herniations lead to subsequent compromise of the nerve root. The root can either have a mere contact with the disc material or be pushed aside or compressed. This was earlier graded by Pfirrmann and colleagues.

Evidence for a hyper-reductive redox in a sub-set of heart failure patients.

Background: Oxidative stress has been linked to heart failure (HF) in humans. Antioxidant-based treatments are often ineffective. Therefore, we hypothesize that some of the HF patients might have a reductive stress (RS) condition.

The unresolved problem of beta-2 microglobulin amyloid deposits in the intervertebral discs of long-term dialysis patients.

Background: Dialysis-related destructive spondyloarthropathy caused by beta-2 microglobulin (β2M) amyloid deposits in intervertebral discs is a major burden for patients undergoing long-term dialysis. This study aimed to quantify the presence of β2M amyloid deposits in the intervertebral disc tissue of such patients and analyze whether there was a significant correlation between β2M accumulation and the duration of dialysis.

Methods: Two groups of patients who had undergone surgery for degenerative spinal pathologies were selected: the dialysis group (n = 29) with long-term dialysis and the control group (n = 10) with no renal impairment.

A Cone Beam Computed Tomography of the Root Canal Morphology of Maxillary Anterior Teeth in an Institutional-Based Study in Chennai Urban Population: An Study.

Aim: This study aims to investigate the root canal anatomy of human extracted permanent maxillary anterior teeth in patients reporting to our dental institution in Chennai using cone beam computed tomography (CBCT).

Materials And Methods: A total of 285 maxillary anterior teeth comprising of 100 central incisors, 85 lateral incisors, and 100 canines extracted from various patients reporting to our institution were studied. The number of roots and number of canals were assessed; following which, the root canal anatomy of each tooth was evaluated for the canal pattern using CBCT.

Carbapenem-resistant Enterobacteriaceae in Pediatric Bloodstream Infections in Rural Southern India.

Objective: To measure the frequency of antimicrobial resistance in pediatric blood culture isolates of Escherichia coli and Klebsiella spp. with focus on carbapenem resistance.

Methods: Over a period of three years, pediatric blood culture isolates were tested for antimicrobial susceptibility, including molecular investigations for carbapenem resistance.

Evaluation of analgesic and anti-inflammatory activity of a combination of tramadol-ibuprofen in experimental animals.

Background: Pain is the major concern of patients attending dental clinics, and satisfactory pain relief has always been difficult to achieve. Since the pathophysiology of pain is a complex, central and peripheral nervous system process, combined analgesic regimens with different mechanisms of action as a multimodal approach are becoming popular among the clinicians and dentists.

Objectives: The aim of the present study was to evaluate the analgesic and anti-inflammatory activity of ibuprofen and tramadol when used alone or in combination in animal models of pain and inflammation.

Prediction of surgical outcomes of laparoscopic liver resections for hepatocellular carcinoma by defining surgical difficulty.

Background: Several classification systems for assessing the surgical difficulty of laparoscopic liver resection (LLR) have been proposed. We evaluated three current classification systems, including traditional Major/Minor Classification, Complexity Classification, and the Difficulty Scoring System for predicting the surgical outcomes after LLR.

Methods: We reviewed the clinical data of 301 patients who underwent LLR for hepatocellular carcinoma between March 1, 2004 and June 30, 2015.

Prevalence of Carbapenem Resistant Non-Fermenting Gram Negative Bacterial Infection and Identification of Carbapenemase Producing NFGNB Isolates by Simple Phenotypic Tests.

Introduction: Non-Fermenting Gram negative bacilli (NFGNB) are emerging multi-drug resistant pathogens causing nosocomial infections. In recent years, carbapenem resistance in NFGNB has increased due to a variety of drug resistance mechanisms, the most common being production of carbapenemases.

Aim: To detect carbapenemase and metallo-β-lactamase (MBL) production in NFGNBs by four phenotypic tests and to compare the various phenotypic methods for detection of carbapenemase and MBL production in nosocomial NFGNB isolates.

A study on total intravenous anesthesia in orthognathic surgical procedures.

Aims And Objective: To assess the use of propofol for induction and maintenance of anaesthesia among patients undergoing various combinations of orthognathic surgical procedures.

Materials And Methods: Following Preoperative evaluation, patients were given Fentanyl (2 micrograms/kg) intravenously. Induction (2 mg/kg) and maintenance (10 mg/kg/hr) of anaesthesia was achieved by Propofol infusion.

The Expression of B7-H3 Molecule in Periodontal Disease.

Statement Of The Problem: T cells have been shown to play a role in the etiopathogenesis of periodontal disease. B7-H3, a costimulatory molecule, is found to be associated with regulation of T cell function in some tumoral tissues, as well as autoimmune and inflammatory diseases.

Purpose: The aim of this study was to investigate the expression of B7-H3 molecule in healthy and diseased gingival tissue samples.

Prevalence of impacted permanent mandibular second molars in South Indian population: A cross-sectional study.

Aims: The aim of this study is to retrospectively determine the prevalence of impacted second molars and associated dental and radiographic findings in South Indian population.

Settings And Design: Cross-sectional design.

Materials And Methods: Dental records of 4976 patients depending on the selection criteria from various dental clinics in South India were retrospectively analyzed in this study.

Significance of BP Control in Reducing Stroke Events: Role of Amlodipine in an Indian Perspective.

While the incidence and prevalence of stroke is gradually decreasing in the western world, a parallel increase is seen in the developing world. It is a matter of special concern to us as approximately 20-30% of stroke occur in people younger than 45 years in India. Indians are prone to higher stroke risk because of urbanization, diabetes, cigarette smoking and high incidence of hypertension.

The 88-kDa Eales' protein in serum is a complex of haptoglobin, complement C3, and galectin-1 as identified by liquid chromatography coupled mass spectrometry.

Purpose: Eales' disease (ED), an enigmatic inflammatory disease, affects peripheral retinal veins and thereby vision in males. This study was aimed at identifying and deciphering the role of a novel 88-kDa protein reported in the serum and vitreous of patients with ED.

Experimental Design: The purified 88-kDa protein was identified by UPLC coupled ESI-QTOF-MS.

Prevalence of antimicrobial resistance in Escherichia coli and Klebsiella spp. in rural South India.

The emergence and dissemination of antimicrobial resistance (AMR) is an important public health problem as resistant organisms cause difficult-to-treat infections. In this study, the prevalence of AMR in Escherichia coli and Klebsiella spp. in rural South India was examined in order to aid empirical therapy.

Current status of laparoscopic liver resection for hepatocellular carcinoma.

Laparoscopic liver resection (LLR) is becoming widely accepted for the treatment of hepatocellular carcinoma (HCC). Laparoscopic left lateral sectionectomy and minor laparoscopic liver resection are now considered standard approaches, especially for tumors located in the anterolateral segments of the liver. Laparoscopic left lateral sectionectomy in adult donors is also gaining acceptance for child liver transplantation in many centers.

Renal fungal ball-two case reports and review of literature.

Fungal ball or fungal bezoar is the saprophytic colonization of a pre-formed cavity by a conglomerate of fungal mycelia without invasion of the adjacent tissue. Fungal bezoar is seen commonly in immunocompromised individuals. We describe the cross-sectional imaging characteristics of two cases of renal fungal ball, a rare clinical entity.
