ABSTRACT: In February 2009 an outbreak of subcutaneous abscesses due to Mycobacterium abscessus was detected in Spain which affected healthy women who had undergone mesotherapy procedures in an aesthetic clinic.
Epidemiological research, health inspection and microbiological studies were conducted. The patients were given antibiotic treatment (according to susceptibility testing) with clarithromycin, and in some cases, combined with amikacin.
Seventeen out of 77 patients treated in the clinic were affected. The products used for the injections were homeopathic drugs in multi-dose vials. The environmental samples were negative. The sterile injection equipment and the clinical procedures were evaluated as correct. The storage conditions for the drugs were also correct, and all the samples tested negative for Mycobacteria. However Paenibacillus provencensis was isolated from samples of unused multi-dose vials and the withdrawal of the product from distribution was ordered. Deficiencies were detected in the sterile products process of at the homeopathic drug factory, so the production line was suspended.
The results of environmental investigation suggest the most likely cause of the outbreak could have been the contamination of the products in the factory, although there was no laboratory confirmation. The widespread use of homeopathic products in invasive procedures requires extreme control during the manufacturing, handling and packaging process. It is important to consider mesotherapy and parenteral use of homeopathic medicines as potential sources of infection and therefore the same precautions in the procedures and quality assurance of products should be applied as with any other drug or medical activity.

ABSTRACT: We describe investigation into an outbreak of norovirus gastroenteritis associated with oyster consumption. A survey was conducted in 346 exposed persons, 266 of whom were cases. Only 14 feces samples from patients were sent to the National Microbiology Laboratory. Oysters collected at the production site were sent to the National Food Center. The oysters met the microbiological quality standard required before sale, which did not include virus investigation. Epidemiological analysis showed an association between gastroenteritis and consumption of oysters (OR = 60.4; 95% CI: 26.2-139.3) and razor shells (OR = 3.13; 95% CI: 1.4-6.9). Microbiological analysis confirmed norovirus in affected individuals but not in the oysters that had been tested after a longer purification period than those consumed. Food with a special risk of norovirus transmission should be strictly monitored. Investigators should dispose of the necessary laboratory resources to study food-borne norovirus outbreaks.

ABSTRACT: The flu season 2009-2010 has been shorter and less severe than expected. Since January 2010, influenza surveillance systems indicated rates of very low incidence of influenza without detection of virus circulation. In this context, a hospital reported a suspected outbreak of severe respiratory disease, the aetiology proved influenza A(H1N1)v. We describe the outbreak and public health measures for their control.
Descriptive study of an outbreak of pandemic influenza virus in a residency home for mentally disabled. Establishment of active surveillance. The case definition of influenza was very sensitive to detect new cases early, treated early and minimize transmission. Steps were taken to contain the influenza virus infection.
Among 38 cases detected 7 had serious complications(all of them with risk factors). There were no deaths. The overall attack rate was 35.2%. The first cases were workers. The residents were ill at the peak of the outbreak, and among workers the presentation was more dispersed. None of the workers and only three of residents had been vaccinated.
Workers possibly have initiated and contributed to the maintenance of transmission. We emphasize the need to comply with vaccination recommendations, not just those with risk factors, but particularly for workers in contact with those.

ABSTRACT: In order for vaccination programs to be carried out properly, it is essential for the vaccination coverage to be known. On the Balearic Islands, the reported coverage was much less than for the rest of Spain. The objective of this study is that of estimating the coverage of the vaccinations included on the recommended schedule up to 18 months of age (4 doses of oral polio, tetanus and diphtheria; 3 doses of whooping cough; 1 dose of measles, rubella and mumps).
A descriptive, cross-sectional study of the population base. The ideal-time frequency distribution estimators and the corresponding confidence intervals were calculated at 95% (CI95%) for a sample of the resident two-year-old (born in 1995) Balearic Island population selected by means of a single-stage conglomerate random sampling based on census sections. The National Public Health System and National Health Institute vaccination records were reviewed, the data from the vaccination document having been requested from the families and the clinical record from the private pediatricians by telephone.
The sample included 606 children, it having been possible to obtain full information on 532 children. Full information was obtained on 377 cases (62%) from the public health sector records. The least degree of coverage was found for the diphtheria vaccine, 518 children having been fully vaccinated, 96.8% (CI95% = 94.8-98.1), the highest degree of coverage having been found for the whooping cough vaccine, 537 children, 98.9% (CI95% = 97.5-99.5).
Good vaccination coverage was found to exist on the Balearic Islands, being similar to what has been being estimated for Spain as a whole. The objective included within the Polio Eradication Plan is accomplished, very little information being gathered from the public sector.
