Bismuth Subgallate as a Local Hemostatic Agent

Background: Patients on clopidogrel increased bleeding risk after surgery. This drug prolonged bleeding time, increased bleeding volume and induced secondary bleeding because its active metabolite inhibited platelets aggregation and interfered with haemostatic plug stabilization. Conventional methods, such as pressing sterile gauze on the surgery site, showed less effective to stop bleeding in patients on clopidogrel. This research aims to prove the haemostatic effect of bismuth subgallate both on normal and delayed platelet aggregation due to clopidogrel.Methods: Twenty-eight Wistar rats were equally and randomly administered with clopidogrel (10 mg/kgBW) or NaCl 0.9% (saline) via oral gavage. After anesthetizing, we amputated transversely their tail 10 mm from the distal tip. Bleeding after amputation was controlled with pressing gauze soaked in saline or bismuth subgallate solution. After 60 seconds, bleeding assays (bleeding time, bleeding volume, and secondary bleeding) have been observed, recorded, and analysed both in normal and clopidogrel groups.Results: Clopidogrel groups had significantly longer bleeding time, greater bleeding volume, and had more secondary bleeding rather than saline groups (p <.05). Using bismuth subgallate as local haemostatic agent decreased bleeding time and bleeding volume significantly (p <.05) both in normal and clopidogrel groups. Conclusions: Bismuth subgallate has a haemostatic effect on both clopidogrel and normal rat tail bleeding models.

In vitro evaluation of chemical decontamination of titanium discs

Peri-implant diseases are caused by bacterial biofilm colonizing implant surfaces. Prevention and management of peri-implant mucositis and peri-implantitis rely on effective biofilm removal. This study aimed to evaluate biofilm removal and cytocompatibility following chemo-mechanical surface decontamination of biofilm-coated titanium discs. Biofilm-coated (Streptococcus gordonii) discs, with either non-modified (smooth) or modified (rough) surfaces, were instrumented using a sterile gauze soaked in one out of four solutions: saline (NaCl), alkaline electrized water (AEW), citric acid (CA) or N-acetyl-l-cysteine (NAC). Non-contaminated, untreated titanium discs served as controls (C). Residual deposits (bacteria and gauze fibers) and cytocompatibility for osteoblast-like cells were evaluated using SEM and immunofluorescence. Cytotoxicity was assessed using WST-8 assay and immunofluorescence. All protocols were equally effective in removing bacteria from smooth surfaces, while AEW and CA were found to be superior at rough surfaces. AEW and NAC were superior in promoting cytocompatibility over NaCl. NAC and CA had a strong cytotoxic effect on osteoblast-like and fibroblast cells. In conclusion, AEW may be beneficial in the decontamination of implant surfaces, effectively removing bacterial biofilm and restoring cytocompatibility.

Ability of dog owners to identify their dogs by smell

Several studies report that olfactory cues play an important role in human life; humans are essentially able to recognize other family members and friends by their odors. Moreover, recent studies report that humans are also able to identify odors of non-conspecifics. The aim of this study was to determine whether dog owners are able to identify their dogs by smell and distinguish the odor of their own dogs from those of other dogs. A total of 53 dog owners (40 females and 13 males of different ages) volunteered to take part in this study. A number of the participants (17) owned 2 dogs; these owners took part in the study twice (i.e., working with only one dog at a time). Sterile gauze pads were used to collect odor samples from the dogs. Each pad was placed in its own sterile glass jar (750 ml) with a twist off lid until the experiment commenced. Participants were asked to identify their own dog´s odor from a line-up of 6 glass containers. This experiment demonstrated that dog owners are capable of identifying their dogs by smell on a significant level. Results of this study additionally suggested that male owners outperformed their female counterparts in the identification process. Moreover, dog owners whose dogs were housed outside had a higher success rate in identification than did participants who kept their dogs indoors with them. The dog owners found it easier to identify dogs that had been neutered, fed dry dog food and bathed less frequently. In general, younger dog owners tended to have more success when attempting to identify their dogs than did their older counterparts.

Teknik Perawatan Tali Pusat terhadap Pelepasan Tali Pusat

The incidence of infection in newborns (BBL) in Indonesia is 24%-34%. Infection in BBL is the number 2 cause of neonatal death by 49%-60%. Neonatal mortality in developing countries is 50% due to umbilical cord infection, sepsis and neonatal tetanus. The purpose of this study was to analyze the effectiveness of umbilical cord care in newborns using dry open technique and sterile gauze against umbilical cord rupture. The type of research was pre-experimental post-test only design and the sample of this study was 30 newborns at the Puskesmas with purposive sampling technique. The study was conducted for 3 months. The results showed that the umbilical cord care technique with the dry open method made the umbilical cord detach faster than the sterile gauze method. The time for releasing the umbilical cord with the dry open method took 123.8 hours and the time for releasing the umbilical cord with sterile gauze took 170.8 hours. The results of the analysis showed the significance value of 0.004 and the Levin test result of 138%. Conclusion there is no more effective between sterile gauze and dry open umbilical cord treatment against umbilical cord detachment. Suggestions for midwives and health workers can socialize postpartum mothers in umbilical cord care for newborns using open techniques and sterile gauze.

Effectiveness of breast milk application on sore nipples among postnatal mothers

Breast feeding is very important for the health and well-being of infants and mothers. It has been traditional way of feeding newborn in our country and is one of the most natural and beneficial acts a mother can do for her child. Areola irritation is regular in breastfeeding ladies during the initial not many days after conveyance. Most of the sore and broke areolas are the aftereffect of wrong situating and connection of the infant at the breast. The present study aims to assess the effectiveness of breast milk application on sore nipples among postnatal mothers in a Saveetha Medical College and Hospital, Chennai. A quantitative pre-experimental one group pretest and post-test research configuration was embraced and the examination was directed with 30 postnatal moms who were chosen by utilizing non-likelihood purposive inspecting method. The organized meeting was utilized to gather segment information and Nipple Trauma Checklist was utilized to survey the sensitive areola. Pretest was directed prior to overseeing the bosom milk by surveying the areola utilizing Nipple Trauma Checklist. Investigator expressed the mother’s breast milk into a sterile gauze piece and gently rubbed over the nipples, allowing it to air dry for 10-15 minutes. Intervention was given for thrice a day for two days and posttest was done on the third day. The study finding shows that critical improvement was seen which unmistakably derives that use of expressed breast milk over areola was discovered to be compelling in the administration of areola irritation among postnatal moms.

Comparison of Three Skin Sampling Methods and Two Media for Culturing Malassezia Yeast

Malassezia is a lipid-dependent commensal yeast of the human skin. The different culture media and skin sampling methods used to grow these fastidious yeasts are a source of heterogeneity in culture-based epidemiological study results. This study aimed to compare the performances of three methods of skin sampling, and two culture media for the detection of Malassezia yeasts by culture from the human skin. Three skin sampling methods, namely sterile gauze, dry swab, and TranswabTM with transport medium, were applied on 10 healthy volunteers at 5 distinct body sites. Each sample was further inoculated onto either the novel FastFung medium or the reference Dixon agar for the detection of Malassezia spp. by culture. At least one colony of Malassezia spp. grew on 93/300 (31%) of the cultures, corresponding to 150 samplings. The positive culture rate was 67%, 18%, and 15% (P < 10−3), for samples collected with sterile gauze, TranswabTM, and dry swab, respectively. The positive culture rate was 62% and 38% (P < 0.003) by using the FastFung and the Dixon media, respectively. Our results showed that sterile gauze rubbing skin sampling followed by inoculation on FastFung medium should be implemented in the routine clinical laboratory procedure for Malassezia spp. cultivation.

Effect of Celox® Powder on Initial Hemostasis After Cardiac Catheterization in Pediatric Patients with Congenital Heart Disease: A Prospective Study

Background: Ordinary pressure dressing for hemostasis after cardiac catheterization is time consuming and might cause some problems, such as pain or loss of blood, which has to be controlled, particularly in pediatric patient. Using Celox® (chitosan) powder dressing might cause quicker initial hemostasis. Methods: In this prospective study, we assessed Celox® powder among patients in hospitals affiliated with Shiraz University of Medical Sciences, from November 2017 to February 2018. The patients were stratified in two groups. The case group included patients for whom Celox® powder was used along with sterile gauze pressure at the puncture site to achieve hemostasis, and the control group those in whom hemostasis was achieved by standard sterile gauze pressure method. Results: Sixty patients under 16 years of age with congenital heart diseases were evaluated and underwent cardiac catheterization. We stratified the patients in two groups called case (30 patients) and control group (30 patients). Considering both arterial and venous initial hemostasis, in the case group, the minimum and maximum, median and mean coagulation time were less than those in the control group; however, the initial hemostasis was statistically significant only in venipuncture site. Also, the venous coagulation time was shorter among the patients weighing less than 10 kilograms in comparison to those with higher weight. In the case group, using Celox® stirred hemostasis toward the lower percentiles, but based on 50th percentile, the distribution in each group was identical. Conclusions: Celox® powder dressing in children led to reduced coagulation time in venipuncture site, and we might recommend utilizing this type of dressing for venous hemostasis in children after venipuncture.

Kaolin-loaded chitosan/polyvinyl alcohol electrospun scaffold as a wound dressing material: in vitro and in vivo studies

Objective: To evaluate the application of a fabricated dressing containing kaolin for skin regeneration in a rat model of excisional wounds. Method: In the present study, kaolin was loaded into electrospun polyvinyl alcohol (PVA)/chitosan polymer blend to develop a composite nanofibrous dressing. To make the yarns, kaolin with weight ratio of 5% was added to PVA/chitosan polymer blend and subsequently formed into nanofibres using the electrospinning method. Scaffolds were evaluated for to their microstructure, mechanical properties, surface wettability, water vapour transmission rate, water-uptake capacity, blood uptake capacity, blood compatibility, microbial penetration test, the number of colonies, and cellular response with the L929 cell line. Rats with full-thickness excisional wounds were treated with kaolin-containing and kaolin-free dressings. Results: The study showed that rats treated with the kaolin-incorporated mats demonstrated a significant closure to nearly 97.62±4.81% after 14 days compared with PVA/chitosan and the sterile gauze, which showed 86.15±8.11% and 78.50±4.22% of wound closure, respectively. The histopathological studies showed that in the PVA/chitosan/kaolin group, dense and regular collagen fibres were formed, while wounds treated with sterile gauze or PVA/chitosan scaffolds had random and loose collagen fibres. Conclusion: Our results show the potential applicability of PVA/chitosan/kaolin scaffolds as a wound care material.
