Human papillomavirus (HPV) can cause clinical or sub-clinical warts on the skin that may itch or burn and can be transmitted through skin-to-skin contact. HPV appears to be a prerequisite for cervical cancer, though most HPV infections do not lead to cancer. HPV vaccines protect against HPV strains 16 and 18, which cause 70% of cervical cancers, potentially preventing 7 out of 10 cervical cancer cases. The vaccines work by generating antibodies to virus-like particles without the viral DNA.

Human Papillomavirus
Human papillomavirus (HPV) is a sexually transmitted virus that can cause genital warts and various cancers such as cervical cancer. There are over 100 types of HPV viruses, with some high-risk types being HPV-16, HPV-18 and HPV-31 that are linked to cervical cancer. While most HPV infections cause no symptoms and go away, persistent infections of high-risk HPV types can cause cancers like cervical cancer years later with HPV-
HPV Virus
HPV stands for human papillomavirus. There are over 100 types of HPV that can cause diseases like genital warts or cell changes leading to cervical cancer. HPV is spread through skin-to-skin genital contact and people may not show symptoms while still being able to spread the virus. The HPV vaccine protects against four high-risk types and is approved for girls and women ages 9 to 26 in the US.
Breast cancer
This document discusses breast cancer epidemiology and risk factors. It begins by describing the normal structure of the breast and types of breast cancer. The most common type is invasive ductal carcinoma. Risk factors include being a woman and aging, as well as factors like family history, early menstruation, late pregnancy/childbirth, and not breastfeeding. Environmental factors like chemicals that mimic estrogen may also increase risk. While some risk factors cannot be changed, maintaining a healthy lifestyle and limiting chemical exposure may help lower breast cancer risk.

- HPV (human papillomavirus) is the most common sexually transmitted infection that can sometimes cause serious illnesses like genital warts and cervical cancer.
- HPV is transmitted through skin-to-skin contact and condoms do not fully prevent transmission.
- While HPV often clears on its own, persistent infections can cause abnormal cell growth.
- There is an effective vaccine that protects against the HPV types that cause 70% of cervical cancers and 90% of genital warts. The vaccine is recommended before sexual debut.
- Widespread HPV vaccination combined with screening programs has significantly reduced HPV infections and related cancers.
Cervical cancer prevention Dr Sharda Jain
Cervical cancer is a major public health problem in India. Human papillomavirus (HPV) infection causes nearly all cervical cancer cases, with HPV types 16 and 18 causing 70% of cancers worldwide. While screening can help reduce cervical cancer rates, coverage in India is low at only 2.6% of women. The HPV vaccine provides primary prevention against HPV infection and can significantly reduce cervical cancer burden when combined with screening programs. Both vaccination and continued screening are recommended for optimal cervical cancer prevention.

HUMAN PAPILLOMA VIRUS INFECTION & CERVICAL CANCER
This document discusses cervical cancer, including its causes, risk factors, symptoms, and treatment/prevention. It notes that cervical cancer is caused by high-risk strains of the human papillomavirus (HPV), especially HPV 16 and 18. HPV works by integrating into the host cell's genome and inactivating tumor suppressor proteins, leading to uncontrolled cell growth. Screening and prophylactic vaccines can prevent most cases of cervical cancer.
Human Papillomavirus
Human papillomavirus (HPV) is a common sexually transmitted infection that can cause genital warts and certain cancers. There are over 100 types of HPV that are transmitted through skin-to-skin contact. While many infections cause no symptoms, some may cause genital warts or lead to cervical, penile, or oral cancers if left untreated. Treatment options depend on the individual case but may include prescription creams, cryotherapy, surgery, or natural resolution over time. HPV is responsible for the majority of cervical cancers and affects thousands of women each year in the United States.
HPV and Cervical Cancer
Cervical cancer is a major health problem, but HPV vaccination and screening can reduce rates. HPV is transmitted sexually and can cause cervical cancer. The vaccine protects against high-risk HPV types 16 and 18, which cause most cancers. Northern Ireland has high HPV vaccination rates. While the vaccine reduces cancer risk, screening is still needed since the vaccine does not protect against all HPV types and cannot help women already infected. In the future, screening may shift to HPV testing as prevalence decreases due to vaccination.
Hpv
- Human papillomavirus (HPV) is a non-enveloped double-stranded DNA virus that can cause various cancers and genital warts. There are over 100 HPV types, with high-risk HPV 16 and 18 causing most cervical and other cancers.
- The HPV vaccines Gardasil (HPV4) and Cervarix (HPV2) protect against HPV 16 and 18 and can prevent cancers caused by these high-risk types if administered before exposure. Vaccination is recommended for girls and boys at age 11-12.
- HPV positive oropharyngeal cancer makes up the majority of oropharyngeal cancers and is associated with improved survival compared to HPV negative orophary
Current HPV Vaccine Recommendation 2022
- The document discusses recommendations for HPV vaccination from international health organizations. It notes that nearly all cervical cancer cases are caused by HPV and cervical cancer disproportionately impacts women in low and middle income countries.
- Recent evidence from trials shows that a single dose of HPV vaccine can provide similar efficacy to 2-3 doses in preventing cervical precancer and cancer. A single dose schedule could make vaccination programs more affordable and scalable.
- India recently launched its first indigenous HPV vaccine. Experts argue that a national single-dose HPV vaccination program for adolescents in India could substantially reduce cervical cancer rates and help eliminate the disease in the country.
Human papilloma virus
Human papillomavirus (HPV) is the most common sexually transmitted infection. There are over 100 varieties of HPV, more than 40 of which can be transmitted sexually and can affect the genitals, mouth, or throat. While many HPV infections cause no symptoms and resolve on their own, some HPV types can cause genital warts and cancers such as cervical, anal, and throat cancers. Regular screening is important for detecting cell changes that may develop due to HPV infection. There is currently no approved test or treatment for HPV in men, but vaccination is recommended for both boys and girls to help prevent HPV infection and related health problems.
Hpv vaccine
HPV (human papillomavirus) is extremely common, with 80% of sexually active people contracting a strain at some point. It causes various cancers and genital warts. While most HPV infections clear on their own, persistent infections increase cancer risk. Vaccines target high-risk HPV strains responsible for 70% of cervical cancers. They provide sustained, high-level immunity for at least 4.5 years with minimal side effects. Screening and vaccination can significantly reduce HPV-related cancers globally.

- HPV is a small, non-enveloped virus with circular double-stranded DNA. Over 100 types exist, with about 30 causing genital infections.
- Types are classified as low, intermediate, or high risk based on cancer-causing potential. High-risk HPV 16 and 18 cause most cervical cancers.
- HPV spreads through sexual contact and can cause genital warts or remain asymptomatic. Persistent infection can lead to cervical pre-cancer.
- The virus infects epithelial cells and hijacks the host cell cycle to replicate.
HPV update in pharmacy
The document discusses two syndromes - complex regional pain syndrome (CRPS) and postural orthostatic tachycardia syndrome (POTS) - that some young women reported developing after receiving HPV vaccines. The European Medicines Agency reviewed the evidence and found no causal relationship between the HPV vaccines and the syndromes. They determined the rates of the syndromes were not significantly different between vaccinated groups and the general population. The conclusion was that CRPS and POTS are not linked to HPV vaccinations, and that all HPV vaccines remain safe and effective.

HPV Vaccine: A Breakthrough In Prevention of Cervical Cancer
Cervical cancer is one of the commonest cancers in women. As it affects young women it has grave
personal, social and economic consequences. It is unfortunate that despite cancer cervix being a preventable
disease, we have failed to reduce the number of deaths related to it. Recent developments in the understanding of the disease process and its link to the oncogenic strains of Human Papilloma Virus (HPV) has opened new avenues in
the way of prevention of cervical cancer.

1) Pap smear screening introduced in 1920s is the best way to prevent cervical cancer by detecting abnormal cells early before symptoms appear.
2) Cervical cancer is the 2nd most common cancer in Sri Lankan women but screening coverage is very low at only 1.3% of women being screened.
3) While HPV vaccination may prevent some cervical cancers, Sri Lanka lacks data on HPV prevalence to justify introducing the expensive vaccine, and increased pap smear screening would be a more cost-effective prevention strategy.
Cervical Cancer
Cervical cancer develops in a woman's cervix. It is usually caused by HPV infection and can be prevented through regular Pap screening tests and HPV vaccination. Early stage cervical cancer may not have symptoms but advanced cases may cause abnormal bleeding. Diagnosis involves examination and testing to determine stage. Treatment options depend on stage but may include surgery, chemotherapy, and radiation. Regular screening is important for prevention.

Human papillomavirus (HPV) is a virus that can cause warts or lead to cancer. There are over 100 types of HPV, with some causing common warts and others linked to cancers like cervical cancer. HPV is very common and spread through skin-to-skin contact, most often during sex. Persistent infection with high-risk HPV types can cause precancerous lesions and cancers over many years if left untreated. Diagnosis involves clinical exams, testing for HPV DNA, and biopsies. Treatment options depend on the infection but may include cryotherapy, medications, or surgery. Vaccines for HPV types 16 and 18 can prevent most cervical cancers if given before exposure to the virus.

Human papillomavirus (HPV) Vaccine
HPV infection and HPV-associated cervical cancer are significant public health issues, with an estimated 11,000 new cervical cancer cases and 4,000 deaths annually in the US. Globally, nearly 500,000 new cervical cancer cases occur each year, mostly in developing countries. Two HPV vaccines (Gardasil and Cervarix) were approved to protect against HPV types that cause cervical cancer and genital warts. However, the long-term effectiveness and safety of the vaccines have yet to be established, as clinical trials only involved small populations followed for a short period of 5 years. Numerous adverse reactions including pain, swelling, fever, and even death have been reported following vaccination. Mandating the HPV vaccine also faces
Human papillomavirus hpv_ (1)
Human Papillomavirus (HPV) is a group of viruses that infect the skin and mucous membranes and cause warts. There are over 100 types of HPV, and over 30 types are sexually transmitted, making HPV a sexually transmitted disease. Certain HPV types can cause cervical cancer and other cancers. Vaccines like Gardasil and Cervarix can protect against HPV types 16 and 18, which cause 70% of cervical cancers. While the vaccines do not protect against all HPV types, regular screening is still important. HPV has no cure, but the body's immune system usually clears the infection within a year. Vitamins and foods high in lycopene can help speed up the immune response.

Human papilloma virus vaccine - Egypt
HPV vaccine in prevention of cancer cervix, what is the situation in Egypt? Is it a Major health problem?
Presentation given on 2010
18- dr. ghazi alsbeih kau 13 may 2015
Human papillomavirus (HPV) is implicated in several cancers including cervical cancer. A study of 174 cervical cancer patients in Saudi Arabia found that 83% were HPV-positive, with HPV-16 and HPV-18 being the most common genotypes detected, together representing 80% of HPV infections. While cervical cancer incidence is low in Saudi women, HPV vaccination may prevent over three-quarters of cervical cancers. However, a national HPV vaccination program may not be cost-effective given the already low incidence of cervical cancer in the country. HPV is also associated with other cancers and vaccination may help reduce cases if shown to be effective against additional cancer types.
Recent updates in hpv vaccines
This document discusses cervical cancer and HPV in India. It notes that India accounts for 27% of new cervical cancer cases and deaths worldwide despite having only 16% of the global population. It is estimated that over 365 women will die from cervical cancer daily in India by 2025. HPV is the main cause of cervical cancer and certain HPV types are also associated with other cancers. The document discusses HPV vaccines as the primary prevention for HPV-related diseases and recommends routine vaccination of girls aged 9-12 years along with catch-up vaccination up to age 26. It provides details on the available HPV vaccines and their efficacy, safety and recommended dosage schedules.

The umbilical cord
The umbilical cord connects the fetus to the placenta and measures approximately 50 cm in length and 2 cm in diameter at term. It contains one vein that carries oxygenated blood to the fetus and two arteries that carry deoxygenated blood away. The cord inserts into the placenta near its center in most cases. Abnormalities can include abnormal insertion points, short or long length, knots, torsion, hematoma, or having a single umbilical artery instead of two.
The placenta
The placenta develops from fetal and maternal tissues to function as the respiratory, nutritive, excretory, barrier and endocrine organ of pregnancy. It transfers oxygen, nutrients and waste between the mother and fetus. The placenta can develop abnormalities in its shape, size, position or adhesion to the uterine wall which may cause complications like preterm birth or hemorrhage. Placental lesions like infarcts may also occur due to conditions like hypertension.
The foetal membranes
The document discusses the fetal membranes, which include the chorion and amnion. The chorion is the outer membrane that is attached to the placenta and uterine wall. The amnion lines the chorion and encloses the fetus and amniotic fluid. The amniotic fluid provides protection and nutrition for the fetus, and aids in temperature regulation and movement. It is composed primarily of water, carbohydrates, proteins and minerals. The amniotic fluid circulates continuously, with production from the fetal membranes, fetal urine and transudation from maternal and fetal blood.
Physiology of reproduction
The document summarizes the key stages in human reproduction from fertilization through early pregnancy development. It describes how sperm mature and are capacitated in the female reproductive tract. Upon ovulation, sperm meet and fertilize the ovum in the fallopian tubes. The zygote then undergoes cell division and develops into a blastocyst that implants in the uterus. The trophoblast cells of the blastocyst invade the uterine lining and develop into a placenta to exchange nutrients and waste with the mother's blood. Major developmental milestones in early pregnancy include chorion, amnion and decidua formation.
Minor complaints during pregnancy
The document discusses several minor complaints that may occur during pregnancy, including gingivitis, ptyalism, heartburn, constipation, hemorrhoids, varicosities, dyspnea, urinary symptoms, leucorrhea, leg cramps, paraethesia, and backache. For each complaint, the causes and recommended treatments are provided.
Diagnosis of pregnancy
This document discusses the diagnosis of pregnancy over three trimesters. In the first trimester, common symptoms include missed periods, morning sickness, frequent urination, and breast changes. Signs include enlarged, soft breasts and uterus, and a softer, purplish cervix. Pregnancy tests detect human chorionic gonadotropin in urine or blood. Ultrasounds can visualize the gestational sac after 4-5 weeks. In the second trimester, symptoms decrease while the abdomen enlarges and fetal movement is felt. Signs include skin changes and palpable fetal parts. The third trimester confirms pregnancy through palpation of fetal parts and auscultation of the fetal heart.
Antenatal care
Antenatal care involves regular checkups during pregnancy to monitor the health of the mother and baby. Checkups include exams, tests, and education on nutrition, exercise, hygiene, warning signs and avoiding risks. The goals are to prevent or treat complications, detect issues, and ensure healthy development. Women receive more frequent exams as their due date approaches, and are instructed on a nutritious diet, moderate exercise, adequate rest, hygienic practices, and when to seek medical help if problems arise.
Postpartum mood disorders
The document discusses postpartum mood disorders, including prevalence, risk factors, screening tools, diagnosis, and treatment options. It notes that postpartum mood disorders range from mild and temporary postpartum blues to more severe postpartum depression and postpartum psychosis. Screening tools like the Edinburgh Postnatal Depression Scale can help identify at-risk women. Treatment involves psychosocial therapies and may include antidepressant medication depending on severity. A multidisciplinary approach is important to address biological, psychological and social factors.
Normal and abnormal puerperium
Uterine fibroids are benign smooth muscle tumors that develop in the uterus. They are the most common solid pelvic tumors, affecting 20-25% of women during their reproductive years. Fibroids can vary in size and location, and may cause heavy menstrual bleeding, pelvic pressure or pain. Treatment options include observation, medical therapy to reduce estrogen levels, or surgical removal of fibroids.
Version
Version refers to changing the fetal lie or position in the uterus. There are three main types: external cephalic version, internal podalic version, and bipolar podalic version. External cephalic version involves manipulating the fetus externally to convert a breech presentation to head-first. Internal podalic version is performed under anesthesia when the cervix is fully dilated to grasp the fetus's feet and convert a transverse lie to breech. Bipolar podalic version uses both internal and external manipulation through a partially dilated cervix for special circumstances. Complications can include fetal distress, premature separation of the placenta, and maternal hemorrhage.
Vacuum extraction (ventouse)
Vacuum extraction is a method to assist in childbirth using suction from a cup placed on the baby's head to help with traction during contractions. There are different types of cups including metal, soft, and bird's cups. Vacuum extraction is indicated when forceps cannot be used and has advantages over forceps like less need for anesthesia and less compression force applied. Complications can include maternal lacerations and cervical injuries or fetal issues like cephalhematomas and scalp lacerations.
Symphysiotomy
Symphysiotomy is a surgical procedure that divides the symphysis pubis bone to widen the pelvis during childbirth. It is indicated when cephalopelvic disproportion makes vaginal delivery difficult or dangerous but cesarean section is not available or advised. The procedure involves making a small incision above the pubic bone and gradually separating the joint using a scalpel. Complications can include bleeding, injury to nearby organs, infection, and long-term issues like incontinence or an unstable pelvis.
Forceps delivery
This document discusses obstetric forceps, which are metal instruments used to extract a baby's head during delivery. It describes different types of forceps and their proper application techniques. Forceps are indicated for prolonged second stage of labor, maternal distress, or fetal distress. Correct application involves inserting one blade along each side of the baby's head. Potential complications include laceration, hemorrhage, nerve injury, or problems for the baby such as skull fractures. Failure to deliver with forceps may require removal and assessment to determine if cesarean section is needed.
Episiotomy
This document discusses episiotomy, which is an incision made in the perineum during childbirth to widen the vaginal opening. It can help prevent tearing and complications. The two main types are median and mediolateral episiotomies. Median episiotomies involve a midline incision while mediolateral incisions extend laterally towards the ischial tuberosity. Episiotomies are usually performed when the vaginal opening is distended during crowning to prevent stretching injuries. They are sutured closed after delivery.
Caesarean section
The document discusses Caesarean section, including indications, types, procedure, complications, and mode of delivery in subsequent pregnancies. A Caesarean section is a surgical procedure to deliver one or more babies through incisions in the abdomen and uterus. The rate of Caesarean sections has increased from 5% in 1970 to 25% in 1990 due to factors such as abandoning difficult procedures in favor of C-sections and increased use for breech births. Complications can include hemorrhage, infections, and injuries to the mother or baby.
Normal labour
Normal labour involves the spontaneous expulsion of a single, mature fetus through the birth canal within 3-18 hours without complications. It occurs when hormonal and mechanical factors cause the cervix to efface and dilate in stages from 3cm to full 10cm dilation. Labour proceeds through four stages: 1) cervical dilation, 2) expulsion of the fetus, 3) expulsion of the placenta, and 4) recovery. The fetus descends through the birth canal with increased flexion to facilitate delivery of the head.
Anatomy of the foetal skull
The fetal skull consists of three parts: the vault, face, and base. The vault is made up of the frontal, parietal, and occipital bones which are separated by sutures. The face extends from the chin to the nose. Fontanelles are soft spots located where sutures meet which are important for assessing fetal position and flexion. The skull has various longitudinal and transverse diameters used to determine which will engage and pass through the birth canal during delivery.
Anatomy of the female pelvis
The female pelvis is divided into the false pelvis and true pelvis. The true pelvis is further divided into the pelvic inlet, cavity, and outlet. The document describes the boundaries and diameters of each region including the anatomical transverse diameter of 13cm at the inlet. It also discusses the pelvic planes and axes, and the Caldwell-Moloy classification of pelvic types including the gynaecoid, anthropoid, android, and platypelloid pelvis.
Active management of normal labour
This document outlines the active management of normal labour in 4 stages: antenatal preparation, first stage (history, exam, procedures), second stage (delivery of baby), third stage (delivery of placenta), and fourth stage (postpartum care of mother and baby). The goal is a healthy delivery with minimal effects. Key procedures include monitoring contractions/fetal heart with a partogram, positioning, nutrition, analgesia, perineal support, and immediate newborn care.
Thyrotoxicosis in pregnancy
Thyrotoxicosis in pregnancy can cause complications like abortion and preterm labour. Clinical features include weight loss, heat intolerance, tremors, and fast heart rate. It is treated with antithyroid drugs like propylthiouracil or carbimazole. Epilepsy in pregnancy commonly presents as grand mal seizures, which are treated with phenobarbitone or phenytoin along with folic acid. Rhesus isoimmunization occurs when an Rh-negative mother develops antibodies against Rh-positive blood from her baby. It can be prevented by giving the mother anti-D immunoglobulin after delivery or pregnancy events involving blood transfer from baby to mother. Affected babies may require monitoring, phot

- 12. How does the vaccine work ? The vaccine is a Virus–like particles [ VLPs ], it has the outer capsid of HPV and looks morphologically similar to The virus, it is highly immunogenic and can generate neutralizing antibodies that can prevent infection in subsequent exposure. In addition, they are not infectious by themselves as they don’t have the oncogenic viral DNA core.

- 15. www.freelivedoctor.com Schedule : : Vaccination will be most effective if introduced prior to onset of sexual activity; therefore, the target will be girls of 12&13 years old. The vaccine is given by injection into the muscle of the upper arm or upper thigh in three doses over six months. Minor side-effects like soreness at the injection site and fever can occur. Rarely it can cause joint pain and urticaria and very rarely bronchospasm. The protection offered by the vaccines lasts at least five years but is probably life long. At the moment boosters are not thought to be needed.
- 16. www.freelivedoctor.com Will the HPV vaccine replace cervical screening programme ? The vaccine protects against 70 per cent of cervical cancers that is caused by HPV-16 &18 and still there is chance of developing the cancer due to other HPV strains like 31,33,35,39,45,51,56,58,59,68,73 and 82. Therefore, for the moment, adult females should continue to rely on Pap smear tests and it seems probable that this will be so for at least the next 20 years because the majority of women already have HPV infection before the vaccines are induced.
- 17. www.freelivedoctor.com Developing countries: In many developing countries which lack organized screening programmes, cervical cancer is the leading cause of female cancer deaths. Such countries would benefit enormously from an effective HPV vaccine. The draw back of the vaccine is that it is expensive, 3 doses are needed and it is administered by injection. Therefore, a second generation HPV vaccines are required that can be produced more cheaply and to be administered as a single dose.
- 18. www.freelivedoctor.com Conclusion: Its really looks like that the use of HPV vaccines is the beginning of the end for HPV-associated diseases in women. Vaccines by themselves are safe and effective, however, the real benefit of a vaccination programme will take 10-20 years to be realized.
