Colposcopy and Treatment of Cervical Intraepithelial Neoplasia: A Beginner's Manual

What no one ever tells you about genital herpes: my personal experience. Herpes is an incurable disease. Does HIV virus dies/inactivates if sufficiently dried (without any other method of destroying) and is there any possibility It can get reactivated it in future? A: bleach. When sterilization equipment is not available, or the instrument cannot be sterilized, high-level disinfection (HLD) is used. According to the Wilderness Medical Society, water temperatures above 160° F (70° C) kill all pathogens within 30 minutes and above 185° F (85° C) within a few minutes. EPA-registered to kill HIV, Hepatitis B, Hepatitis C, Influenza A, MRSA, Norovirus, VRE, Rotavirus, Adenovirus, Poliovirus, Tuberculocidal, and Fungicidal in 1-10 minutes.

The basic steps involved in the safe utilization of reusable instruments for colposcopy and treatment of cervical intraepithelial neoplasia (CIN) are summarized in this chapter. Gloves should be worn when cleaning up blood spills. Any lack of compliance with this process can lead to contamination of the sterilized instruments and harm to the patient. The process for re-use of the instruments begins with decontamination and continues through cleaning, sterilization/HLD, storage and handling. A quality assurance programme will help to ensure that instruments are processed adequately for re-use. “Decontamination” is a process of treatment that renders a device, instrument, or environmental surface safe to handle but does not necessarily mean that it is safe for patient use (5,6). These are briefly discussed and the methods used for sterilizing different instruments are described.

Mercedez e-mailed in this question: ‘Does it help to spray your mattress with bleach to kill bed bugs?’. Vaginal yeast infections, caused by a species of yeast found virtually all normal people, are common infections women. If these procedures are carried out properly, decontamination of the instruments will be assured before handling for cleaning. Six months ago, I sat waiting in my gynecologist’s exam room chair, fully clothed and wishing I were anywhere else. Further processing is necessary to ensure that the object is cleaned and then sterilized. 1) After drying, 90 to 99% of the viruses die within hours accroding to CDC. Interesting, but I share…

Instruments should be cleaned as soon as possible after use. Then, smell the water. Sterilization is defined as the process of destroying all microorganisms on an instrument by exposure to physical or chemical agents. This process kills all forms of microbial life including bacterial spores. In practice, sterility is considered to be achieved if the probability of a surviving microorganism is less than one in a million. The sterilization process is fundamental for the safe reuse of instruments in clinical care. When sterilization equipment is not available, or the instrument cannot be sterilized, HLD is used.

Disinfection implies that the microbial burden of an instrument is reduced, but not entirely eliminated. In , the Environmental Protection Agency (EPA) product label terminologies are compared with the CDC germicidal process terminology (6,9). In practice, however, HLD results in all forms of microbial life being destroyed except bacterial spores. How to Treat a Cat Virus With Lysine. The 0.5% chlorine solution can be prepared by adding one part of concentrated household bleach (sodium hypochlorite solution, 5% available chlorine) to nine parts of water. The general formula for making a dilute solution from a commercial preparation of any given concentration is as follows: Total parts of water = [% concentrate/% dilute] -1. I was in so much pain with teeny tiny barely visible blisters around private area.

For example to make a 0.5% dilute chlorine solution from a dry powder of 35% calcium hypochlorite = [0.5%/35%] x 1000 = 14.2 g. to the upper post 1. A: I think you’ve misheard the news. Thorough manual cleaning of instruments with water and detergent to remove all organic material, after decontamination in 0.5% chlorine solution for 10 minutes, is of the utmost importance before to sterilization or HLD. Bleaching powder, liquid bleach, chlorine tablets and other sources of chlorine may be used, depending on local availability. Instruments should be cleaned as soon as possible after use, so that no organic material will dry and stick to the instruments, providing a sanctuary for microbes. The person cleaning should use utility gloves while washing instruments.

Protective glasses or goggles should be worn by the cleaners to protect their eyes from contaminated water. Special attention should be given to instruments with teeth (e.g., biopsy punches), joints and screws (e.g., vaginal specula), to which biological material can become stuck. After cleaning, rinse the instruments thoroughly with boiled water to remove detergent residue. Instruments that are considered ‘critical’ (instruments entering sterile body tissues or vascular system, see Table 14.1, e.g. The lack of viral replication indicated inactivation of the virus by the disinfectant. Two methods of sterilization are described here. One of the best things you can do to prevent cold sores is to make lysine a bigger part of ..

Unwrapped instruments should be exposed for 20 minutes to temperatures between 121-132oC at a pressure of 106 kPa (15 lb/inch2). You should follow the manufacturer’s advice, as pressure settings may vary slightly depending on the make of the autoclave. If I catch his herpes in the first month or 2 months of my pregnancy that I didn’t know,is there any possibility that it will affect our baby’s health?Is there any safe method having sex w/my husband so that I can get pregnant without catching his herpes? The material used for wrapping should be porous enough to let steam through. Some animal viruses, for instance, produce latent infections, in which the virus persists in a quiet state, becoming periodically active in acute episodes, as in the case of the herpes simplex virus. Salmonella croaks at a measly 165. Small autoclaves are ideal for use in clinics.

Disinfecting kills a variety of germs including bacteria such as Staph, Salmonella and E. This requires special handling with gloves, and the instruments thus sterilized should be rinsed with sterile water before use, as these chemicals form a residue on the instruments. Glutaraldehyde is very expensive, while formaldehyde is more irritating to skin, lung and eyes. Steam sterilization is preferred to chemical sterilization. Two methods of HLD are described here: (a) Boiling plain tap water in a clean vessel offers a cheap and readily accessible form of HLD. The contact time for instruments should be at least 20 minutes after boiling has started. Water in the vessel should be changed daily.

Chlorine compounds can provide high degrees of disinfection. 0.1% Chlorine solution: If boiled water is used to make the solution, 0.1% chlorine may be used for HLD. If not, one should use 0.5% solution. The contact time required is 20 minutes. The solution is very corrosive to stainless steel. I have herpes simplex type one so the Cold sore type but my question is I don’t get it on my lips I get it on my tummy on the right side across from my belly button I’ve had it since I was 7 and I’m 26 now I was just wondering if anyone knew of anything I can so as it’s so painful and it can last for about two weeks and the tablets you can get don’t work. The shelf life of prepared solution is one week.

6% Hydrogen peroxide solution:It can be prepared by adding one part of a 30% solution to four parts of boiled water; the contact time is 30 minutes. That said, even… However, this solution will damage the external surfaces of rubbers and plastics, and corrode copper, zinc, and brass instruments after prolonged use. 2% Glutaraldehyde: It must be prepared according to the manufacturer’s instructions; activated 2% solution in a covered container has a shelf life of two weeks. The contact time is 20 minutes. As glutaraldehyde forms a residue on instruments, which is toxic to tissues, the instruments must be rinsed thoroughly with sterile water and dried with a sterile cloth before use. Strict implementation of decontamination, cleaning, and sterilization or HLD of instruments, according to a written manual is helpful in quality assurance of the procedures.

The manual must be prominently displayed in the clinic for ready reference. The quality assurance process includes regular audits, analysis, system adjustments and education. The audits should include review of the methods of sterilization used, the items being sterilized, the length and temperature of exposure, identification of the person performing the sterilization, and periodic review and inspection of equipment being used for sterilization. There was a step-wise increasing resistance to disinfection as the in vivo situation was approached. Spaulding categorized medical instruments as ‘critical’, ‘semi-critical’, or ‘non-critical’, according to how they are used (Table 14.1). This is useful in guiding their processing for reuse. Intermediate-level disinfection results in destruction of Mycobacterium tuberculosis, vegetative bacteria, most viruses (HIV, hepatitis B and herpes Simplex viruses) and most fungi (Candida, Aspergillus), but does not kill bacterial spores.

Low-level disinfection destroys most bacteria, some viruses, some fungi, but not Mycobacterium tuberculosis or bacterial spores. In recent years I have been using antiviral medication when I feel a tingling around my lips, and that has worked very well. While alcohol does not leave a residue on instruments, iodophors do. A guide to the processing of instruments and materials used for screening of cervical neoplasia, colposcopy and treatment of CIN is given in Table 14. 2. Procedure tables, trolleys, equipment (colposcope, cryosurgical equipment, electrosurgical generator, smoke evacuator, halogen lamp, etc.) in the screening clinic may be contaminated with body fluids such as vaginal secretions, purulent discharge, blood, etc. While the surface of the procedure table should be decontaminated after each patient procedure, the other surfaces should be decontaminated on a daily basis by wiping with 0.5% chlorine solution, 60-90% ethyl or isopropyl alcohol or other chemical disinfectants such as iodophors.

The floor of the screening clinic should also be decontaminated on a daily basis.

Yesterday I had consensual protected sex which ended in the guy storming out as usual, I’ve had unprotected sex with the same person, now 8 days prior. Sometimes herpes sores may not be visible in women, so a change in discharge may be the only clue. If it is a vaginal infection, would taking antibiotics help? You need to speak to the appropriate medical professionals to help you with your problem if you ever want to get rid of it. So that a doctor can diagnose a vaginal infection, he or she may need to examine the outer genital skin and the inner vaginal lining. The inflammatory lesions are associated with mucopurulent, seropurulent, white or serous discharge and symptoms such as lower abdominal pain, backache, pruritus, itching and dyspareunia. It had no odor nor was there any stinging, burning or itching.

Common infectious organisms responsible for such lesions include protozoan infections with Trichomonas vaginalis; fungal infections such as Candida albicans; overgrowth of anaerobic bacteria (Bacteroides, Peptostreptococcus, Gardnerella vaginalis, Gardnerella mobiluncus) in a condition such as bacterial vaginosis; other bacteria such as Chlamydia trachomatis, Haemophilus ducreyi, Mycoplasma hominis, Streptococcus, Escherichia coli, Staphylococcus, and Neisseria gonorrhoea; and infections with viruses such as herpes simplex virus. I cannot avoid some clothes, because of my job, and I go to the gym alot, so sweating is going to be hard to keep control of as well. Your doctor will be able to provide you with the information you need if you have a problem with herpes, but if you suffer bacterial vaginosis then you can purchase many products over the counter to help with this problem. Irritation and soreness of the vulva are the usual symptoms, sometimes but not always, accompanied by a thick, white vaginal discharge. Examination of the external anogenitalia, vagina and cervix for vesicles, shallow ulcers and button-like ulcers and the inguinal region for inflamed and/or enlarged lymph nodes, and lower abdominal and bimanual palpation for pelvic tenderness and mass should be part of the clinical examination to rule out infective conditions. The term cervicovaginitis refers to inflammation of the squamous epithelium of the vagina and cervix. In cervicovaginitis, the cervical and vaginal mucosa respond to infection with an inflammatory reaction that is characterized by damage to surface cells.

This damage leads to desquamation and ulceration, which cause a reduction in the epithelial thickness due to loss of superficial and part of the intermediate layers of cells (which contain glycogen). In the deeper layers, the cells are swollen with infiltration of neutrophils in the intercellular space. If the treatment doesnt work or the symptoms return, see your doctor. The underlying connective tissue is congested with dilatation of the superficial vessels and with enlarged and dilated stromal papillae. Cervicitis is the term used to denote the inflammation involving the columnar epithelium of the cervix. It results in congestion of underlying connective tissue, desquamation of cells and ulceration with mucopurulent discharge. If the inflammation persists, the villous structures become flattened, and the grape-like appearance is lost and the mucosa may secrete less mucus.

In both the above conditions, after repeated inflammation and tissue necrosis, the lesions are repaired and necrotic tissue is eliminated. It causes a fishy smell and occasionally vaginal itching and burning. Examination, before application of acetic acid, reveals moderate to excessive cervical and vaginal secretions, which may sometimes indicate the nature of underlying infection. In T. vaginalis infection (trichomoniasis), which is very common in tropical areas, there is copious, bubbly, frothy, malodorous, greenish-yellow, mucopurulent discharge. Bacterial infections are associated with thin, liquid, seropurulent discharge. The secretion may be foul-smelling in the case of anaerobic bacterial overgrowth, bacterial vaginosis, and Trichomonas infection.

It is not clear how BV is related to sexual activity, although there may be a link with having a new sexual partner and a high lifetime number of sexual partners. Foul-smelling, dark-coloured mucopurulent discharges are associated with inflammatory states due to foreign bodies (e.g., a retained tampon). Gonorrhoea results in purulent vaginal discharge and cervical tenderness. Small vesicles filled with serous fluid may be observed in the cervix and vagina in the vesicular phase of herpes simplex viral infection. Herpetic infections are associated with episodes of painful vulvar, vaginal and cervical ulceration lasting for two weeks. Excoriation marks are evident with trichomoniasis, moniliasis and mixed bacterial infections. The treatment is with the antibiotic metronidazole, available only on prescription.

Chronic inflammation may cause recurrent ulceration and healing of the cervix, resulting in distortion of the cervix due to healing by fibrosis. There may be associated necrotic areas as well. A biopsy should be directed if in doubt. Rare and uncommon cervical infections, due to tuberculosis, schistosomiasis and amoebiasis, cause extensive ulceration and necrosis of the cervix with symptoms and signs mimicking invasive cancer; a biopsy will confirm the diagnosis. If the infectious process is accompanied by marked ulceration (with or without necrosis), the ulcerated area may be covered with purulent exudate, with marked differences in the surface level of the cervix. The main symptoms are vaginal discharge and pain passing urine, but there may be no symptoms in the early stages. Longstanding bacterial, fungal or protozoal infection and inflammation may lead to fibrosis, which appears white or pink, depending on the degree of fibrosis.

The epithelium covering the connective tissue is fragile, leading to ulceration and bleeding. Appearances following acetic acid and iodine application are variable, depending on the integrity of the surface epithelium. In the case of cervicitis, the columnar epithelium is intensely red, bleeds on contact and opaque purulent discharge is present. The columnar villous or grape-like appearance may be lost due to flattening of the villi, to repeated inflammation and to the fact that there are no clearly defined papillae (Figure 9.1). The infection is caused by the herpes simplex virus being passed during sex. The liberal application of acetic acid clears the cervix and vagina of secretions, but may cause pain. Cervicovaginitis is associated with oedema, capillary dilatation, enlargement of the stromal papillae, which contain the vascular bundles, and infiltration of the stroma with inflammatory cells.

Chronically inflamed cervix may appear reddish, with ill-defined, patchy acetowhite areas scattered in the cervix, not restricted to the transformation zone and may bleed on touch (Figures 9.2, Figures 9.3). The enlarged stromal papillae appear as red spots (red punctation) in a pinkish-white background, usually in the case of T. vaginalis infection, after application of acetic acid. Frequent severe attacks may require regular antiviral treatment for up to a year. However, one can differentiate using the following criteria: inflammatory punctations are fine, with extremely minimal intercapillary distances, and diffusely distributed (not restricted to the transformation zone) and they involve the original squamous epithelium and vagina with intervening inflamed mucosa. As the inflammation persists and becomes chronic, it results in large, focal red punctations due to large collections of capillaries grouped together, which appear as several red spots of different sizes visible in a pinkish- white background, producing the so-called ‘strawberry spots’ (Figure 9.4). Colposcopically, a chronically inflamed cervix may sometimes resemble invasive cervical cancer (Figure 9.5).

The test outcome after application of Lugol’s iodine solution depends upon the desquamation and the loss of cell layers containing glycogen. If desquamation is limited to the summit of the stromal papillae where the squamous epithelium is thinnest, a series of thin yellow spots are seen on a mahogany-brown background, giving a stippled appearance (Figure 9.6). Chlamydia, gonorrhoea, herpes and trichomoniasis are sexually transmitted diseases (STDs) that can cause vaginal symptoms. These features are often found with Trichomonas infection, but also may be seen with fungal and bacterial infections. If there is marked desquamation, the cervix appears yellowish-red in colour, with involvement of vagina (Figure 9.8). In summary, inflammatory conditions of the cervix are associated with excessive, usually malodorous, mucopurulent, seropurulent or whitish discharge, red punctations, ulceration, and healing by fibrosis. The secretion is frothy with bubbles in the case of trichomoniasis and sticky cheese white in candidiasis.

Inflammatory lesions of the cervix may be differentiated from CIN by their large, diffuse involvement of the cervix, extension to the vagina, red colour tone and associated symptoms such as discharge and pruritus.
