[Implementation of the International Health Regulations in Cuba: evaluation of basic capacities of the health sector in selected provinces].

Objective: Obtain baseline information on the status of the basic capacities of the health sector at the local, municipal, and provincial levels in order to facilitate identification of priorities and guide public policies that aim to comply with the requirements and capacities established in Annex 1A of the International Health Regulations 2005 (IHR-2005).

Methods: A descriptive cross-sectional study was conducted by application of an instrument of evaluation of basic capacities referring to legal and institutional autonomy, the surveillance and research process, and the response to health emergencies in 36 entities involved in international sanitary control at the local, municipal, and provincial levels in the provinces of Havana, Cienfuegos, and Santiago de Cuba.

Results: The polyclinics and provincial centers of health and epidemiology in the three provinces had more than 75% of the basic capacities required.

Low prevalence of Helicobacter pylori among symptomatic children from a hospital in Havana, Cuba.

The aims of this study were to assess the prevalence of Helicobacter pylori infection and to introduce a new algorithm to improve its diagnosis in Cuban symptomatic children. One hundred and thirty-three consecutive children with upper gastrointestinal symptoms were studied. Patients were endoscoped and antral biopsies were obtained for rapid urease test (RUT), culture and histology.

Kaposi's sarcoma-associated herpesvirus load in asymptomatic contacts of Cuban epidemic KS patients.

To evaluate the pathogenic mechanisms and transmission routes involved in KSHV infection in 22 Cuban individuals who maintained close contact with epidemic KS patients, real-time PCR was used to quantify KSHV-DNA in clinical samples of plasma, saliva and peripheral blood mononuclear cells (PBMC). KSHV-DNA was detected in 72.7% (16/22) of the contacts.

Phenotypic and genetic characterization of antimicrobial profiles of Helicobacter pylori strains in Cuba.

The study evaluated the antibiotic resistance patterns of Helicobacter pylori strains against metronidazole and clarithromycin in a hospital in Havana, Cuba. Eighty-five percent, 22.5%, and 10% of 40 H.

Simultaneous quantification of human herpesvirus 8 DNA by real time PCR in different tissues of HIV infected cuban patients with Kaposi's sarcoma.

In Cuba, previous reports have shown an increase of epidemic KS, reaching a total of 120 cases by the end of 2007, despite the use of HAART. To evaluate and compare the role of human herpes virus 8 (HHV-8) viral loads in different compartments of AIDS-related Kaposi's sarcoma (AIDS-KS) patients real-time polymerase chain reaction (RT-PCR) was used to determine the genome copy number of HHV-8 in plasma, saliva, tissue and peripheral blood mononuclear cells (PBMC) of 49 AIDS-KS patients. Overall, 98% of AIDS-KS patients harbored detectable HHV-8.

[Response capacity for epidemic emergencies: recommendations for country self-evaluation].

Communicable diseases that have appeared or reappeared in recent years have demonstrated their great potential for spreading and their capacity to overwhelm a country's resources, causing major emergencies. The recent SARS epidemic showed that only health systems that have been strengthened and that have the response capacity for events of this kind will be able to handle future contingencies. Governments have recognized the need to support initiatives to strengthen their countries' capacities in surveillance, prevention, and the control of emergencies caused by epidemics.
