OBJECTIVE: To estimate the status of HIV infection and AIDS incidence using a back-calculation model in Korea. METHODS: Back-calculation is a method for estimating the past infection rate using AIDS incidence data. The method has been useful for obtaining short-term projections of AIDS incidence and estimating previous HIV prevalence. If the density of the incubation periods is known, together with the AIDS incidence, we can estimate historical HIV infections and forecast AIDS incidence in any time period up to time t. In this paper, we estimated the number of HIV infections and AIDS incidence according to the distribution of various incubation periods RESULTS: The cumulative numbers of HIV infection from 1991 to 1996 were 708~1,426 in Weibull distribution and 918~1,980 in Gamma distribution. The projected AIDS incidence in 1997 was 16~25 in Weibull distribution and 13~26 in Gamma distribution. CONCLUSIONS: The estimated cumulative HIV infections from 1991 to 1996 were 1.4~4.0 times more than notified cumulative HIV infections. Additionally, the projected AIDS incidence in 1997 was less than the notified AIDS cases. The reason for this underestimation derives from the very low level of HIV prevalence in Korea. Further research is required for the distribution of the incubation period of HIV infection in Korea, particularly for the effects of combination treatments.

The prevalence of HIV infection is gradually increasing every year. Rhinosinusitis and complaints in relation to olfactory dysfunction are common in HIV-infected patients. These are rarely life-threatening but otolaryngologist should treat these patients aggressively, because rhinosinusitis and olfactory dysfunction can have a negative impact on the patients'quality of life. This paper covers these issues so that otolaryngologists may reasonably prevent, diagnosie, and treat persons suffering from rhinosinusitis and olfactory dysfunction related to HIV infection.

Background: Lai Chau is one of northwestern provinces of Vietnam, where there was a drug vice and high prevalence of drug users. It is necessary to evaluate the situation of HIV infection in this group. Objectives: A study on HIV prevalence and factors relating to the behaviors of HIV Infection among Injecting Drug Users (IDUs) in various districts of Lai Chau province. Subjects and method: A quantitative, cross-sectional study was carried out on 330 IDUs in Lai Chau town and 3 districts of Lai Chau province from January to December 2007. Results: 40.30% of the IDUs tested positive for HIV, nearly 2 times higher than the prevalence in 2006 (23.2%). 87.27% of the IDUs never re-used their syringes and needles. However, 12.4% still sometimes re-used their syringes and needles. Of 43 IDUs (12.73%) who re-used their syringes and needles, only 27.91% always cleaned their syringes and needles, 23.26% cleaned their syringes and needles most of the time after using them and up to 27.91% only sometimes cleaned their syringes and needles. Most IDUs use heroin (97.88%). Percentage of IDUs sharing syringes and needles accounts for 12.42%. 10% of the IDUs had sexual intercourses with commercial sex workers within the last month. There is a relationship between the time of using drugs and the HIV prevalence rate. There is a double risk of HIV infection for the IDUs injecting drugs for 5 years and upwards compared to those injecting drugs less than 5 years. (p <0.05, OR = 2). Conclusion: It is required to develop communications in order to change the behaviors of HIV infection among IDUs in Lai Chau province.

HIV (human immunodeficiency virus) is an increasing concern in the South Pacific. We estimate, based on reported figures, that the prevalence of HIV infection in women attending antenatal clinics in Fiji in 2003 was 0.04%. The number of children born to HIV-positive mothers is small, though perinatal transmission appears to be high. Fiji's preliminary strategies for prevention of perinatal transmission have been significant, but require ongoing support and implementation.

We compared the performance of three screening kits for the detection of anti-HIV in 187 samples; Enzygnost Anti-HIV 1/2 Plus, ABBOTT TESTPACK HIV- 1/HIV-2 & SERODIA. HIV- 1/2. Four samples, 3 serums and 1 CSF, from 2 patients were repeatedly reactive in all three screening kits and 2 serum specimens were confirmed positive(HIV-1) by the western blot assay. The sensitivity and specificity of all three screening kits were 100% and 98.9%, respectively. In Korea, the cause of AIDS is mostly HIV-1 and the prevalence is very low. So, all three screening kits were useful for the detection of anti-HIV from patients and blood donors. But the use of screening kit for the detection of anti-HIV-1, anti-HIV-2 and anti-HIV-I subtype O will be needed for the decrement of false negative rate because HIV infection has been increased, especially, HIV-2 infection and pediatric AIDS patient by vertical transmission were also reported, currently.

Antiretroviral therapy for treatment of human immunodeficiency virus type 1 (HIV-1) infection has improved steadily since the introduction of combination therapy in 1996. With the advancement of antiretroviral therapy, the mortality of AIDS patients has markedly improved. However, drug resistance has been emerging as a major problem in HIV treatment. Several studies reported that the prevalence of transmitted resistant virus involving antiretroviral-naive people in developed countries was around 10%. Primary drug resistance is rare in HIV-1 infected patients in Korea. A cohort study is need to monitor resistant HIV-1 among newly infected individuals.

Syphilis was a common cause of progressive or sudden sensorineural hearing loss. After introduction of penicillin, the incidence of syphilis decreased in general population. However, with the prevalence of HIV infection, it's incidence is increasing. Many studies have substantiated the aggressive and rapidly progressive behavior of neurosyphilis, including otosyphilis, in the presence of HIV infection . We report a case of 38-year-old man HIV infected patient with bilateral sensorineural hearing loss and bilateral total vestibular loss caused by otosyphilis which was resistant to treatment.

To assess the prevalence of HIV infection in patients with sexually-transmitted diseases(STD), we screened STD patients who visited STD clinics in Seoul area during the period of April 1993-Octorber 1993. Blood samples were collected by unlinked anonymous method, and antibodies against HIV were screened. Fi-ve hundred and thirty patients with STD werescreened. Median age of the patients was 23 year. Male to female ratio was 1:2.8. None of the patients had HIV antibody. The prevalence of HIV infection in STD patients was estimated to be less than 5%.

OBJECTIVES: Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) adversely impacts food security in households of people living with HIV/AIDS (PLWHA). Little research has focused on food insecurity among PLWHA in India. The purpose of this study was to identify the prevalence of and factors relating to food security in households of PLWHA in the Siliguri subdivision of Darjeeling, West Bengal, India. METHODS: A cross-sectional community-based study was carried out among 173 PLWHA residing in Siliguri and registered at the Anti-retroviral Therapy Centre of North Bengal Medical College & Hospital. Data was collected at the household level with interviews of PLWHA using a food security survey instrument. We analyzed the associations using logistic regression. RESULTS: The prevalence of household food security among the participants was 50.9% (88/173). Five years or more of schooling, higher socioeconomic class and males were found to be significantly associated with a higher likelihood of food security. A later stage of the disease and the presence of other family members with HIV/AIDS were significantly associated with a lower likelihood of food security. The major coping strategies to deal with food insecurity in the acute phase HIV infection included borrowing money (56.1%), followed by spousal support, loans from microfinance institutions, banks, or money lenders, borrowing food, or selling agricultural products. CONCLUSIONS: The present study revealed that only about half of households with PLWHA were food secure. Prior interventions relating to periods of food and economic crisis as well as strategies for sustaining food security and economic status are needed in this area.
