Objective: To compare the health impact and economic benefits among individuals who did not receive the human papillomavirus (HPV) vaccine to those who received a single dose, or 2 doses. The comparison was stratified by 4 types of vaccine in conjunction with primary HPV screening in a low/middle-income country setting.

Methods: A Markov model was employed to simulate HPV infection and cervical cancer in a cohort of 100,000 12-year-old girls free of HPV.

Background: The human papillomavirus (HPV) vaccine was introduced into Thailand's national immunization program in 2017 for 11-12 year old school girls. The objectives of this study were to examine the epidemiological consequences and cost-effectiveness of a routine quadrivalent HPV (4vHPV) vaccination and the routine 4vHPV vaccination plus 5-year catch-up vaccination by comparing with cervical cancer screening only (no vaccination) in Thailand.

Method: A transmission dynamic model was used to assess the cost-effectiveness of the routine 4vHPV vaccination and the routine 4vHPV vaccination plus catch-up vaccination, compared with no vaccination (screening only) in Thai population.

To identify the optimal cost-effective strategy for cervical cancer screening program in Thailand by comparing the different algorithms which based on the use of primary human papilloma virus (HPV) assay. We use a Microsoft Excel-based spreadsheet to calculate the accumulated cases of preinvasive and invasive cervical cancer and the budget impact of each screening program. The model was developed to determine the cost-effectiveness of 3 screening strategies: pooled HPV test with reflex liquid-based cytology triage, HPV genotyping with reflex p16/ki67 dual stain cytology, and pooled HPV test with dual stain.

Objectives: To assess the clinical and cost-effectiveness of human papillomavirus (HPV) primary screening triage with p16/Ki-67 dual stain cytology compared to cytology.

Methods: We conducted an Excel®-based budget impact model to estimate the preinvasive and invasive cervical cancer cases identified, mortality rate, direct medical costs, quality-adjusted life years (QALYs) and the incremental cost-effectiveness analysis of two strategies from the healthcare payer perspective. The study population is a cohort of women 30-65 years of age presenting for cervical screening.

Objectives: The aim of this study is to compare the cost and benefit of four different cervical cancer screening strategies involving primary HPV 16/18 genotyping, hrHPV testing alone and cytology for detecting CIN2 +.

Methods: Economical analysis using Markov modeling approach to combine the epidemiological data from current population-based study of The National Cancer Institute of Thailand. A cohort of 100,000 hypothetical female population age 30-65 years was simulated in each strategy.

Objective: The aim of this study was to compare the efficacy of HPV 16/18 genotyping test, high risk HPV DNA testing, alone and in conjunction with the liquid-based cytology method in screening for cervical cancer precursors. Methods: A Markov model was used to describe the course of the cases of CIN2+ that had been detected over a 35 year period. Screening programs started at age 30 and were performed at an interval of once every five years.

Background: There is no standard treatment for patients with platinum-resistant or refractory epithelial ovarian cancer. Single agent chemotherapies have evidence of more efficacy and less toxicity than combination therapy. Most are very expensive, with appreciable toxicity and minimal survival.

Design: An Economical Analysis based on a retrospective study.

Subject: The women who were referred to the gynecological department due to screening result of ASC-US at King Chulalongkorn Memorial Hospital, a general and tertiary referral center in Bangkok Thailand, from Jan 2008 - Dec 2012.

Aim: The aim of this study was to test: (i) the validation and reliability of the Thai versions of overactive bladder (OAB) questionnaires (the 8-item and 3-item Overactive Bladder Symptoms Score questionnaires [OAB-v8 and OAB-v3, respectively] and the Overactive Bladder Questionnaire [OAB-q]); and (ii) the correlation of the OAB-v8, OAB-v3, and the single-question Quality of Life Questionnaire (1-QoL) to the OAB-q in Thai women with OAB.

Material And Methods: During January to March 2011, 36 Thai women with OAB attending a urogynecology clinic at Chulalongkorn Hospital, Bangkok, Thailand were recruited. All questionnaires were given as a psychometric test twice, 2 weeks apart.

This paper relates to the first phase one of a three-phase study. Phase 1 investigated and identified risk factors for work-related musculoskeletal disorders (WMSDs) in 26 'One Tambon One Product' (OTOP) groups working in the informal sector. Data was collected from 93 participants in Khangkoi District, Saraburi Province, Thailand during 2009-2010.

Objective: To determine health related quality of life (QoL) of patients diagnosed with cervical intraepithelial neoplasia (CIN) and cervical cancer compared QoL among stages of cancer and to study the association between QoL and patients' characteristics.

Material And Method: The questionnaire elicited information and QoL using Functional Assessment of Cancer Therapy General (FACT-G) questionnaire. The study population was patients with a diagnosis of one of the four FIGO stages of cervical cancer

Results: One hundred seventy two patients completed the present study.

Corrosive ingestion can produce severe upper gastrointestinal tract injury with long-lasting suffering and even death. Early assessment of the extent of damage is important, not only for treatment, but also for hospitalization. We did a prospective study to determine the prognostic value of initial signs and symptoms as indicators of the degree of gastrointestinal injury.

Thailand is a canine rabies endemic country with an annual prevalence above 1,000 reported animals diagnosed rabid . Over 345,000 humans are treated for possible rabies exposures annually . Lack of perception of the disease burden, social, cultural and traditional beliefs play an important role in the failure of canine rabies control.

Objective: To conduct a hospital-based survey to assess women's attitude and acceptance towards menopause and hormone replacement therapy (HRT).

Method: The authors conducted a survey in women who visited the menopause clinic in 5 university and public hospitals in Bangkok. A group of 615 women who lived in those catchment areas and voluntarily cooperated in responding to a set of standardized questionnaires was randomly selected.
