OBJECTIVES: This study aimed to evaluate the therapeutic effect of 1% povidone-iodine mouthwash combined with scaling and root planing in patients with stage Ⅰ/Ⅱ class A/B periodontitis, and to provide a basis for the clinical application of povidone-iodine mouthwash. METHODS: Seventy-five subjects were included in this trial and randomly divided into three groups. After full-mouth ultrasonic supragingival cleansing, scaling and root planing, the placebo group was treated with sodium chloride injection (NaCl group), the control group was treated with compound chlorhexidine mouthwash (CHX group), and the experimental group was treated with 1% povidone-iodine mouthwash (PVP-I group), and rinsed their mouths for 1 week, respectively. Subjects were tested at 1, 4, and 12 weeks after dosing for clinical indicators, microbial composition of supragingival plaque, gingival crevicular fluid inflammatory marker levels, and patient-reported outcomes. RESULTS: Sixty-three subjects completed the follow-up. After treatment, the clinical indicators, microbial indicators, and inflammatory indicators were all significantly improved (P<0.05). Comparisons among the groups showed that one week after treatment, the bleeding index and plaque index of the CHX group and the PVP-I group were lower than those of the NaCl group, and the plaque index of the CHX group was lower than that of the PVP-I group (P<0.05). There were no statistically significant differences in the other clinical indicators among the groups (P>0.05). Twelve weeks after treatment, the Shannon index of the CHX group was lower than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other microbial indicators among the groups (P>0.05). Twelve weeks after treatment, the interleukin-10 concentration of the CHX group was higher than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other inflammatory indicators among the groups (P>0.05). The PVP-I group had the highest scores in terms of taste and oral odor. There was no obvious staining on the tooth surfaces and mucosa in all three groups. CONCLUSIONS 1% PVP-I mouthwash combined with scaling and root planing can effectively reduce gingival inflammation and dental plaque, improve clinical symptoms in the short term. While its efficacy is not significantly inferior to that of chlorhexidine, PVP-I mouthwash is more acceptable to patients than chlorhexidine.

Inflatable penile prostheses are an important tool in the treatment of medically refractory erectile dysfunction. One of the major complications associated with these prostheses is infections, which ultimately require device explanation and placement of a new device. Over the past several decades, significant work has been done to reduce infection rates and optimize treatment strategies to reduce patient morbidity. This article reviews the current state of knowledge surrounding penile prosthesis infections, with attention to the evidence for methods to prevent infection and best practices for device reimplantation.

INTRODUCTIONInadequate oral care has been implicated in the development of aspiration pneumonia in frail geriatric patients and is a major cause of mortality, due to the colonisation of microbes in vulnerable patients. This type of pneumonia has been associated with an increase in respiratory pathogens in the oral cavity. The aim of this study was to evaluate the effects of chlorhexidine compared to routine oral care in edentulous geriatric inpatients.

METHODSA double-blind, parallel-group randomised controlled trial was carried out. The intervention group received oral care with chlorhexidine 0.2%, while the control group received routine oral care with thymol. Nurses provided oral care with assigned solutions of 20 mL once daily over seven days. Oral cavity assessment using the Brief Oral Health Status Examination form was performed before each oral care procedure. Data on medication received and the subsequent development of aspiration pneumonia was recorded. An oral swab was performed on Day 7 to obtain specimens to test for colonisation.

RESULTSThe final sample consisted of 35 (control) and 43 (intervention) patients. Chlorhexidine was effective in reducing oral colonisation compared to routine oral care with thymol (p < 0.001). The risk of oral bacterial colonisation was nearly three times higher in the thymol group compared to the chlorhexidine group.

CONCLUSIONThe use of chlorhexidine 0.2% significantly reduced oral colonisation and is recommended as an easier and more cost-effective alternative for oral hygiene.

Effective final irrigation regimen is an important step in order to achieve better disinfection and ensure residual antimicrobial effects after root canal preparation. The aim of this study was to compare the residual antimicrobial activity of 0.2% cetrimide, and 0.2% and 2% chlorhexidine in root canals infected with Enterococcus faecalis. Biofilms of E. faecalis were grown on uniradicular roots for 4 weeks. After root canal preparation, root canals were irrigated with 17% ethylenediaminetetraacetic acid (EDTA) to remove the smear layer. The roots were randomly divided into three experimental groups (n=26) according to the final irrigating solution: Group I, 5 mL 0.2% cetrimide; Group II, 5 mL 0.2% chlorhexidine; and Group III, 5 mL 2% chlorhexidine. Samples were collected for 50 days to denote the presence of bacterial growth. The proportion of ungrown specimens over 50 days was evaluated using the nonparametric Kaplan-Meier survival analysis. Differences among groups were tested using the log-rank test and the level of statistical significance was set at P<0.05. The highest survival value was found with 2% chlorhexidine, showing statistically significant differences from the other two groups. At 50 days, E. faecalis growth was detected in 69.23% specimens in Groups I and II, and in 34.61% specimens of Group III. There were no significant differences between 0.2% cetrimide and 0.2% chlorhexidine. Final irrigation with 2% chlorhexidine showed greater residual activity than 0.2% chlorhexidine and 0.2% cetrimide in root canals infected with E. faecalis.

The purpose of this study was to evaluate the relation between ocular discomfort and ocular Demodex infestation, and therapeutic effects of tea tree oil (TTO) in Demodex blepharitis patients. Three hundred and thirty-five patients with ocular discomfort were evaluated for ocular Demodex infestation and subjective symptoms with ocular surface discomfort index (OSDI) score. Among them, Demodex-infested patients were randomized to receive either eyelid scrubbing with TTO (TTO group,106 patients) or without TTO (Control group, 54 patients) for 1 month. Demodex were found in 84% of patients with ocular discomfort. The number of Demodex was significantly correlated with age (P = 0.04) and OSDI score (P = 0.024). After eyelid scrub treatment, Demodex count was reduced from 4.0 +/- 2.5 to 3.2 +/- 2.3 in the TTO group (P = 0.004) and from 4.3 +/- 2.7 to 4.2 +/- 2.5 in the control group (P = 0.27). Also, OSDI score was reduced from 34.5 +/- 10.7 to 24.1 +/- 11.9 in the TTO group (P = 0.001) and from 35.3 +/- 11.6 to 27.5 +/- 12.8 in the control group (P = 0.04). In conclusion, Demodex number showed a significant positive correlation with age and subjective ocular discomfort. The tea tree oil eyelid scrub treatment is effective for eliminating ocular Demodex and improving subjective ocular symptoms.

Orthognathic surgery is frequently accompanied by intermaxillary fixation. Intermaxillary fixation impedes the maintenance of effective oral hygiene and prolonged fixation can result in periodontal disease. A potential shorter term effect is the generation of oral malodour. It is unclear, however, as to how the production of malodorous compounds in the oral cavity is altered post-surgery. Oral air concentration of sulphur containing compounds, short chain organic acids, ammonia, isoprene and acetone were measured using selected ion flow tube-mass spectrometry in a patient who had undergone orthognathic surgery with subsequent intermaxillary fixation. Total sulphide levels rose approximately 5-fold during fixation with metal ties, with smaller increases recorded for the other compounds measured with the exception of isoprene which remained close to baseline levels. Organic acid levels declined markedly once elastic ties had replaced metal ties, with a lesser reduction being observed in sulphide levels, with both declining further after the commencement of a chlorhexidine-containing mouthwash. These data suggest that bacterial generation of a variety of malodorous compounds increases markedly following intermaxillary fixation. This single case also suggests that the use of elastic ties and effective oral hygiene techniques, including the use of chlorhexidine mouthwash, may help ameliorate such post-surgical effects.

OBJECTIVETo evaluate the wound healing potential of fractions from ethanol extract of Martynia annua (M. annua) Linn leaves.

METHODSEthanol extract of M. annua Linn leaves was fractionate into three different fractions (MAF-A, MAF-B and MAF-C) which were screened for wound healing potential using two models: excision and incision on rats. The thin layer chromatography (TLC) profile of all fractions were analyzed and TLC of luteolin was also done. The Povidone-Iodine Ointment was used as reference for comparision. Excision and incision wounds were created on dorsal portion of rats for study. Wound contraction, biochemical parameters (protein level and hydroxyproline level) and histopathological study were performed in excision wound model whereas incision model was used for determination of tensile strength.

RESULTSThe wound contraction and tensile strength of skin tissues were observed significantly greater in MAF-C fraction treated group than other two fractions (P<0.01). In excision wound method (on day 18) protein content and hydroxyproline were found significantly higher in MAF-C group than control group (P<0.01). Histopathological study also showed better angiogenesis, matured collagen fibres and fibroblast cells as compared with the control group.

CONCLUSIONSIn conclusion, our findings suggest that fraction MAF-C from ethanol extract of M. annua leaves is found most effective in wound healing.
