background and objective: cervical cancer involves many women annually and pop smear test has played a significant role in reducing its mortality and for this reason, its improvement is very essential. in this respect, cervex brush is a new tool that has been introduced in many countries. therefore, this study was conducted to compare pop smears from cotton swab-spatula and cervex brush methods...

Human bite mark evidence is often found in violent crimes. Due to the difficulties of physically comparing an injury site on elastic and curved skin surfaces to the teeth of a suspect, the authors have considered using salivary DNA evidence to identify the bite perpetrator. Several techniques were evaluated to determine the best method of recovering saliva from human skin before extracting geno...

BACKGROUND Our previous study showed that cotton-swab cryotherapy is an alternative treatment modality for oral leukoplakia. METHODS This study used liquid nitrogen spray with a cryogun (cryogun cryotherapy) to treat 60 oral leukoplakia lesions. RESULTS Complete regression was achieved in all 60 oral leukoplakia lesions after cryogun cryotherapy. We found that 60 oral leukoplakia lesions tr...

Objective : An attempt was made to compare the detection of cervical abnormalities between the use of a cotton swab and a Cervex brush in mass cancer screening. Study Design : Of 15,664 women who participated in a cervical cancer screening program in 2002, 8,366 women underwent Cervex brush sampling and 7,298 underwent cotton swab screening to compare the detectability of dysplasia and cancer i...

Preparation • Dissolve 1 heaped teaspoonful of salt or sodium bicarbonate in a jug containing 500 ml of boiled water (half a litre); allow this solution to cool (Figure 1). • Pour a very small amount of the solution into a small sterile pot on a clean surface (Figure 2). Method 1 The eyelashes • Ask the patient to close both eyes. • Take a folded gauze swab or cotton bud. • Moisten the swab or ...

Samples for forensic DNA analysis are often collected from a wide variety of objects using cotton or nylon tipped swabs. Testing has shown that significant quantities of DNA are retained on the swab, however, and subsequently lost. When processing evidentiary samples, the recovery of the maximum amount of available DNA is critical, potentially dictating whether a usable profile can be derived f...

BACKGROUND Cervical cancer incidence and mortality rates in Bolivia are among the highest in Latin America. This investigation aims to evaluate the possibility of using simple devices, e.g. a cotton swab and a glass slide, for self-sampling in order to detect human papillomavirus (HPV) DNA by PCR in cervico-vaginal cells. METHODS In the first phase of our study we evaluated the use of a glass...

BACKGROUND Oral leukoplakia (OL) is a common oral precancerous lesion. Cotton-swab cryotherapy (CSC) is commonly used for treating skin lesions but is rarely used for treating OL lesions. METHODS Sixty OL lesions were treated by CSC once every 2 weeks until complete regression (CR) of the lesion had been achieved. RESULTS CR was achieved in all 60 OL lesions after an average of 6.3 treatmen...

A comparison between nonspatula (cotton swab and Cytobrush) cervical sampling methods and spatula (wooden Ayre spatula and plastic extended-tip Szalay Cyto-Spatula) sampling methods was made in 109 cases. Based on the presence of endocervical cells, there were statistically significant qualitative differences between the non-spatula methods as well as between the spatula methods, but not betwee...

Four varieties of swabs held in plastic containers and three swab transport media kits, all obtainable in the United Kingdom, were tested to assess their effectiveness in the isolation of Bordetella pertussis. The highest isolation rates up to 48 hours were obtained with Dacron swabs held in plastic containers. Swab-transport media kits proved unsatisfactory. B pertussis may have a stronger aff...
