Effect of Staining Beverages on Color Stability of Composite: A Spectrophotometric Study.

Objective: This study used spectrophotometry to examine how staining beverages affect the color stability of three commercial composite materials (nanohybrid composite (A), bulk fill composite (B), and flowable composite (C)) over time.

Materials And Methods: Composite discs were randomly divided into groups. The specimens were kept in coffee, tea, red wine, and cola for 14 days at 37°C in the dark.

Assessment of Outcome of Oral Supplementation of Vitamin D3 as an Adjunct to Scaling and Root Planing in Chronic Periodontitis Patients with Type II Diabetes Mellitus - A Randomized Controlled Clinical Trial.

Background: Both diabetes and periodontitis affect millions of people worldwide and Vitamin D insufficiency may create a conducive environment for the progression of diabetes and periodontal disease. The aim of the study was to assess the outcome of oral supplementation of Vitamin D3 in patients with Type 2Diabetes Mellitus with generalized chronic periodontitis, as an adjuvant toscaling and root planing.

Methodology: A total of 92 patients, including 46 each in non-diabetic and diabetec group.

Cancer Hospital Stockpiles: Strategizing for an Efficient and Sufficient Inventory List of Essential Items.

Purpose: The COVID-19 pandemic has affected health care systems worldwide, resulting in critical shortages of essential items and materials. The available guidelines are of little use for cancer hospitals in low-income and low-middle-income countries. They have been designed for community hospitals serving in a centralized health care network.

Development of an in-house hospital information system in a hospital in Pakistan.

Objectives: To review our experience of development and implementation of an electronic hospital information system, its costs and return on investment as well as incorporation of some key quality standards.

Methods: Cost and saving trends of the project were calculated using different tools including project expense, cost saving through cessation of printing radiology films and paper. Net present value with payback period was utilized to evaluate the efficiency of the health information systems.

Respiratory viruses in children attending a major referral centre in Saudi Arabia.

Viral respiratory infections are common causes of illness in infants and children. Examination of clinical specimens submitted for diagnosis during a 3-year period (August 1993-July 1996) at King Faisal Specialist Hospital and Research Center (KFSH & RC) in Riyadh revealed a wide spectrum of diseases associated with the isolation of five respiratory viruses. Severity of disease ranged from mild upper respiratory illness to threatening lower respiratory illnesses including bronchiolitis and pneumonia.

Controlled study of fluconazole in the prevention of fungal infections in neutropenic patients with haematological malignancies and bone marrow transplant recipients.

The efficacy and safety of oral fluconazole versus a polyene regimen in preventing mycoses in neutropenic patients was compared. Patients with haematological malignancy or bone marrow transplantation received as antifungal prophylaxis either fluconazole 200 mg daily or a regimen consisting of clotrimazole trouches 10 mg twice daily with mycostatin, 500,000 I.U.

Diagnostic dilemma and therapeutic non-compliance in a case of intracranial tuberculoma.

A case of extensive intracranial tuberculoma is presented. The patient had been treated for 5 years with a standard antituberculosis regimen but she had been grossly non-compliant. This had led to emergence of multi-resistant Mycobacterium tuberculosis producing progressive disease and extensive cranial nerve damage and proptosis.

Gel filtration high performance liquid chromatography of envelope polypeptide variants of herpes simplex type 1 strains.

High performance liquid chromatography (HPLC) with a TSK-4000SW gel filtration column was used to compare envelope polypeptides from four strains of herpes simplex virus type 1 (HSV-1). The chromatographic profiles demonstrated polypeptide variability among three clinical strains and the wild-type F strain. Radioimmunoprecipitation of the HPLC fractions with polyclonal anti-HSV-1 followed by SDS-polyacrylamide gel electrophoresis (PAGE) of the immunoprecipitates revealed molecular weight differences of various polypeptides in fractions from the area containing major peaks.

Susceptibility of clinical isolates of yeasts to anti-fungal agents.

The antimicrobial activity of amphotericin B, 5-fluorocytosine, nystatin, clotrimazole and miconazole were compared in vitro against 244 strains of yeasts that had been isolated from clinical specimens. The yeasts used in this study included 20 species of Candida, Cryptococcus, Saccharomyces Geotrichum, Rhodotorula, Torulopsis and Trichosporon. The majority of the strains (78%) had an MIC of less than or equal to 0.

Rapid detection of methicillin-resistant staphylococci with the MS-2 system.

The ability of the updated Abbott MS-2 system to detect methicillin-resistant Staphylococcus aureus (MRSA) was compared with disk agar diffusion and broth microdilution. Of the 87 MRSA isolates tested, the MS-2 system correctly detected 85 (97.7%) in 5 h.

An evaluation of the gram stain and chocolate agar culture as part of a routine urine culture set-up.

A total of 219 urine specimens were Gram stained and inoculated onto 5% sheep blood, eosin methylene blue and chocolate agars. Culture and smear results were evaluated to determine if the Gram stain and chocolate agar culture yielded further meaningful information. Additional information was gained in 42 (19%) of the specimens; however, most of the results were not considered significant.
