Abstract

Bacterial plaque has the primary etiologic role in triggering the pathological changes of periodontal disease. A major goal of periodontal therapy is supraand subgingival bacterial flora reduction through scaling and root planning, through local and general antimicrobial treatment. The aim of our study was to evaluate the effectiveness of the mechanical treatment of scaling and root planning in reducing or suppressing bacterial species from the periodontal pockets. In order to conduct this study we collected and analyzed subgingival plaque samples taken from the 50 periodontal pockets with a depth of about 5mm, from 50 subjects with diagnosis of generalized chronic periodontitis, before and after scaling and root planning. The usage of API 20A test allows a quick and easy identification of anaerobic bacteria based on biochemical properties. Additional complementary tests were used, such as examining the culture and the morpho-tinctorial features to confirm and complete the identification. The microbial flora that we were able to isolate from the periodontal pockets before scaling and root planning was very rich. After scaling and root planning the subjects showed clinical improvement in the periodontal status, and the microbiological analysis of the periodontal pockets mostly showed a quantitative and qualitative reduction of bacterial species. A local or general antimicrobial treatment is recommended to assure improved effectiveness because mechanical treatment alone cannot completely suppress bacterial flora.

Abstract

Pediatricians frequently encounter hematuria in children. One of the tardy complication of pulmonary tuberculosis, which is most characteristic and common in teenagers and middle aged, is represented by genitourinary tuberculosis. Renal tuberculosis is rare during childhood. The authors present a series of cases where the presenting symptom was gross or microscopic persistent hematuria. The diagnosis of urogenital tuberculosis was established from early-morning urine culture in all cases. In a patient with symptoms of recurrent urinary tract infection or hematuria associated with sterile pyuria the suspicion of GUTB must be considered. A delayed diagnosis of renal tuberculosis led to kidney damage and sequels of GUTB, including renal failure. Our cases report emphasizes that in case of persistent hematuria GUTB may be considered as a differential diagnosis

Abstract

The clinical relevance of Staphylococcus aureus strains with heterointermediate susceptibility to vancomycin (hVISA) is still controversial, however they could be responsible for treatment failures in patients treated with vancomycin. The lack of standardization and the complexity of testing methods are the main challenge in indentifying such strains. The aim of our study was to evaluate the frequency of hVISA strains in Targu-Mures Clinical Emergency Hospital. One hundred twenty-two, non-duplicate, methicillin-resistant S. aureus (MRSA) isolates susceptible to vancomycin using standard E-test (MIC≤2 mg/L) were screened for heteroresistance with Glycopeptide Resistance Detection test (E-test GRD). Population analysis profile-area under the curve (PAP/AUC) method was used for confirmation. Twenty-four strains (19.5%) were found positive with the screening method. Two of them (1.63%) were confirmed having hVISA phenotype and no strains with intermediate vancomycin susceptibility (VISA) were detected. In conclusion, the rate of MRSA strains with reduced vancomycin susceptibility was low. However, their monitoring may be useful, taking into consideration the wide usage of glycopeptides in the treatment of serious MRSA infections.
