[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]. / Episodios de salmonelosis no tifoidea en pacientes adultos del Área Valladolid Oeste en 2017: Evaluación de la idoneidad de la petición del cultivo microbiológico y del tratamiento pautado.

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.

[Prevalence of human papillomavirus in Spanish women from a population screening program]. / Prevalencia de virus del papiloma humano en mujeres españolas de un programa de cribado poblacionales de riesgo.

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.

[A descriptive study of Hafnia alvei isolated from stool samples: an approach to its clinical assessment]. / Descriptivo de Hafnia alvei aisladas en coprocultivo: aproximación a su valoración en clínica.

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.

Detección del VPH en mujeres con y sin alteraciones citológicas del cérvix en Castilla y León: estudio poblacional / Detection of HPV in women with no cellular alterations detected in uterine cytology in Castilla y León, population study

RESUMEN OBJETIVO: estimar la prevalencia de cambios y alteraciones cervicales en mujeres pertenecientes al Programa de Prevención y Detección Precoz de Cáncer de Cuello del Útero de Castilla y León, e identificar la coexistencia y genotipo más frecuente del VPH. MATERIALES Y MÉTODOS: estudio cuantitativo, observacional, descriptivo, transversal, retrospectivo, efectuado en mujeres de 25 a 64 años de edad que participaron en las pruebas de cribado de 2012 a 2014. Los resultados de la citología cervical convencional se interpretaron de acuerdo con la clasificación Bethesda 2001. La detección y genotipificación del VPH se realizó con PCR. Las variables cualitativas se describen mediante frecuencias absolutas y relativas (porcentajes) de sus categorías, con IC95% . Para estudiar la asociación entre variables cualitativas se utilizó la prueba de χ2. Se consideró estadísticamente significativo el valor de p≤0.05. RESULTADOS: se analizaron 190,203 muestras de frotis de cuello uterino. El 66.4% de las muestras citológicas no mostró lesiones ni alteraciones morfológicas. De las muestras citológicas con alteraciones se identificaron 7,083 con metaplasia, 2,844 con células escamosas atípicas (1.5%), 855 con lesiones de bajo grado (0.4%), 255 con lesiones de alto grado (0.13%) y 198 con lesiones cancerosas (0.1%). Las lesiones intraepiteliales de bajo y alto grado, además de los carcinomas, fueron más frecuentes en las muestras positivas a VPH (p<0.001). En relación con la atrofia vaginal de mujeres perimenopáusicas, los genotipos más frecuentes fueron el VPH-53 (0.7%), VPH-31 (0.6%) y VPH-58 (0.5%). En pacientes con lesiones intraepiteliales el genotipo más frecuente fue el VPH-16. CONCLUSIONES: la prevalencia del VPH suele ser más alta conforme aumenta la severidad de la lesión citológica detectada. El genotipo aislado con mayor frecuencia en lesiones intraepiteliales de alto o bajo grado es el VPH-16.

ABSTRACT OBJECTIVE: To estimate the prevalence of cervical changes and alterations in women belonging to the Program for the Prevention and Early Detection of Cervical Cancer of Castilla y León, and to identify the most frequent presence and genotype of Human Papilloma Virus (HVP). MATERIAL AND METHODS: A quantitative, observational, descriptive, cross-sectional, retrospective study of women aged 25-64 years who participated in screening tests during 2012 and 2014. The results of conventional cervical cytology were interpreted according with the Bethesda 2001 classification. The detection and genotyping of HPV was performed across PCR. Qualitative variables are described by absolute and relative frequencies (percentages) of their categories, with a 95% confidence interval (CI 95%). To study the association between qualitative variables, the χ2 test was used. The value of p≤0.05 was considered statistically significant. RESULTS: 190,203 samples of cervical smears were analyzed during the period. 66.4% of the cytological samples showed no lesions or morphological alterations. Of the cytological samples with alterations we identified 7,083 with metaplasia, 2,844 with atypical squamous cells (1.5%), 855 with low grade lesions (0.4%), 255 with high grade lesions (0.13%) and 198 with cancerous lesions%). Low- and high-grade intraepithelial lesions, in addition to carcinomas, were more frequent in HPV positive samples (p <0.001). To the vaginal atrophy of perimenopausal women we detected HPV-53 (0.7%), HPV-31 (0.6%) and HPV-58 (0.5%) genotypes. In patients with intraepithelial lesions the most frequent genotype was HPV-16. CONCLUSIONS: the prevalence of HPV is usually higher according to the severity of the cytological lesion detected. The most frequently isolated genotype in high-grade low-grade intraepithelial lesions is HPV-16.

Fluvoxamine for stereotypic behavior in patients with dementia.

OBJECTIVE: To describe the effects of treatment with the selective serotonin reuptake inhibitor fluvoxamine on three patients with advanced dementia who developed a stereotypic movement disorder. CASE SUMMARY: Three patients in a skilled nursing facility were referred by their primary physicians for psychiatric consultation to assist with the management of stereotypic behaviors. The patients received a standard medical, neurologic, and psychiatric workup for dementia. Two of the patients were diagnosed with dementia of the Alzheimer type and the other patient was diagnosed with vascular dementia. All three patients were started on fluvoxamine 25 mg/d; behaviors were monitored daily by the nursing staff and their primary care physicians and weekly by their psychiatrist using the Abnormal Involuntary Movement Scales. The dosage was titrated upward weekly to a maximum dosage of 150 mg/d. RESULTS: Two patients showed complete resolution of their stereotypic behaviors by week 6. The third patient showed noticeable improvement with some residual movements after 8 weeks of treatment. CONCLUSIONS: Fluvoxamine appeared effective in the control of stereotypic behaviors in three patients with advanced dementia.
