[Episodes of nontyphoidal salmonellosis in adult patients of the Valladolid West Area in 2017: Evaluation of the suitability of the microbiological culture request and the prescribed treatment]

OBJECTIVE

Gastroenteritic salmonellosis is still the second cause diagnosed of infectious diarrhea, most of these clinical pictures are mild and self-limited and therefore the use of antibiotics is limited to few cases. The aim of the study was to describe the episodes of diarrhea caused by Salmonella enterica subsp. enterica, assessing the suitability of the request and the use of antibiotics according to the criteria included in the methodology.

METHODS

A retrospective, descriptive, observational study was conducted, collecting data from the clinical history.

RESULTS

A total of 122 episodes were included. The reason for consultation was diarrhea, which generated a greater demand in the Hospital Emergency Services (42.6%). The most frequent serotypes isolated were Enteritidis (53.3%), and Typhimurium (40.2%). The adequate request of the stool was 90.2%. Antibiotic was prescribed in 64.6% (79) of the episodes, most patients under 65 years (58 episodes), the average age was 48.43 years. They were treated mainly with ciprofloxacin and azithromycin, in 57 and 14 episodes, respectively. The average duration of antibiotic treatment was 6 days. There was an adequate use of antibiotics in 49.1% of episodes. When the origin of the request was the Hospital Emergency Service, it was inadequate in 63.5% (33) of them. It was inadequate in 60.0% (39) of episodes when ser. Enteritidis was isolated. Almost half, 48.85% (42) of the 58 episodes in which antibiotics were prescribed among those under 65 (86), were treated without being indicated.

CONCLUSIONS

Training actions should be implemented focused on optimizing the management of antibiotics in this entity.

[A descriptive study of Hafnia alvei isolated from stool samples: an approach to its clinical assessment]

OBJECTIVE

The importance in human diarrhoeal disease of Hafnia alvei is unclear. The objective of the study was to describe the population which was isolated H. alvei in stool cultures and the therapeutic management of these cases in our Health Area.

METHODS

A descriptive retrospective study was carried out in 2014 and 2015. Epidemiological, clinical, treatment and evolution variables were collected in the computerized clinical history.

RESULTS

A collection of 7,290 stool specimens were processed, 3,321 in 2014 and 3,969 in 2015, of which 58 (1.7%) and 53 (1.3%) were positive for H. alvei, respectively. A 60.4% of samples were isolated in women. The mean age was 38.68 years. A 68.5% of samples were from primary care. In 71.2% there was related clinic, diarrhoea in 57.7%. In 75.7% of the cases there was not associated underlying disease. A 43.2% of the cases received treatment. A 66.7% of treated patients came from Primary Care. The mean duration of treatment was 8 days. The evolution was favourable in 85.4% of the cases treated. All strains were susceptible to ciprofloxacin and trimethoprim/sulfamethoxazole.

CONCLUSIONS

More evidence is needed to support H. alvei as a cause of gastroenteritis.

[Prevalence of human papillomavirus in Spanish women from a population screening program]

OBJECTIVE

The human papillomavirus (HPV), is necessary to cause a woman developing cervical cancer. The aim of the study was to estimate the prevalence of women with HPV infection, covered by the program of prevention and early detection of cervical cancer of Castile and León (Spain).

METHODS

Samples of women included in the screening program were analyzed. Including a total of 120,326 cervical swab samples, collected in the period from January 2012 to December 2014.

RESULTS

12,183 HPV positive samples were detected, representing a prevalence of 9.6 ‰, (IC 95% 9.5%-9.8%) in the female population. High-risk HPV were found in higher proportion that HPV low-risk genotypes. HPV prevalence correlates inversely with women age. Coinfections of multiple genotypes were found in one third of screened women population.

CONCLUSIONS

Data showed in this study are the first and wider Spanish results from a cervical cancer screening program population non opportunistic based on HPV detection. These results would serve as a reference for future prevalence studies and to evaluate the future impact of HPV vaccination campaigns.
