Management of anorectal malformations during the newborn period

Anorectal malformations comprise a spectrum of disease. Some of these defects are minor, with an excellent functional prognosis. Others are complex and may be associated with other defects in the urinary tract that may risk the patient's life. The decision-making process for the management of a newborn with anorectal malformations is crucial; the timing and establishment of priorities are the key to success. Because the management of affected males and females differs significantly, they are discussed separately.

Resumen Las malformaciones anorrectales comprenden todo un espectro de enfermedad. Algunos de los defectos son de naturaleza menor, fáciles de tratar y tienen un excelente pronóstico funcional. Otros son complejos, su manejo es difícil, su pronóstico incierto y algunoas veces se ven asociados con otros defectos en el tracto urinario que significan riesgo para la vida del paciente. El proceso de toma de decisión en el manejo de un recién nacido con malformación anorrectal es crucial porque determina el futuro inmediato y lejano del niño. Las más importantes decisiones a tomar durante este período son las relativas a la necesidad de una colostomía y sí el paciente requiere una derivación urinaria o vaginal con el fin de prevenir sepsis o acidosis metabólica. La definición de prioridades y su programación son la clave del éxito. Puesto que el manejo de estos pacientes difiere significativamente en los niños y en las niñas, se discuten por separado en este informe.

Résumé Il existe une grande variété de malformations anorectales de l'enfant. Les malformations dites mineures sont faciles à réparer et leur pronostic est excellent. Parmi les variétés complexes, le traitement est difficile, le pronostic incertain, et parfois, lorsqu'il s'y associe des malformations urinaires, la vie de l'enfant est en jeu. De la décision thérapeutique, dépend étroitement le pronostic immédiat et tardif. Les problèmes essentiels concernent la décision de réaliser ou non une colostomie ou encore la nécessité de pratiquer une dérivation urinaire ou vaginale afin d'éviter une infection ou une acidose métabolique. Le traitement des malformations diffèrent naturellement entre le garçon et la fille et sera traité séparemment.

     

Predictive equation for acquisition of hepatitis B in hospital workers in a general hospital

A cross-sectional study was performed to obtain risk factors for hepatitis B disease, HBsAg carriers and immunised personnel, among 2470 workers in a general hospital in Madrid, Spain. The data obtained were analyzed with multiple logistic regression to obtain coefficients for variables. The results of the analysis show that being a nurse or being regularly exposed to blood are the most important risk factors for hepatitis B acquisition. The length of time working at the same job activity was also a risk factor. The resulting coefficients allow the construction of a predictive equation for non-immunised, HBsAg carrier and immunised HBV status, which can select subjects for a hepatitis B vaccination program.     

Calcitonin,estradiol, and hydroxyproline as parameters in the early diagnosis of involutional osteoporosis

Summary Bone metabolism was studied in a group of 92 subjects. A greater age-related decrease in calcitonin and estradiol concentrations exists in women than in men, though this difference was not significant; it was significant, however, when the values of the three different groups of women were compared. We present what we have called the second calcitonin phenomenon, that is, a highly significant difference in women between a second basal calcitonin level and the primary admission value. In the calcium infusion test, men considered to be osteoporotic showed a deceleration in the rapid loss of reserve calcitonin deposits.     

The income level and life styles: towards a law of inverse prevention?

The study of the determinants of disease-related lifestyles may be relevant for better understanding the potential of health policies. In the present work, results of the analysis of the Elche Healthy Cities Interview Survey prevalence of some disease related lifestyles (physical activity level, cigarette consumption, and alcohol intake) are presented according to economic level as measured by monthly family income, 573 people randomly selected from the town rolls were interviewed at home. No associations were found between economic level and alcohol intake or present smoking status. But, trying to stop smoking and regular exercise were more frequent behaviors in higher economic groups. The ratio of prevalence of regular exercise was 1.73 in favor of the highest economic levels. The gradient found was statistically significant (chi 2 for trend = 17.4, p less than 0.01). The results may be of relevance when implementing health policies to overcome inequalities in health: "unequal interventions" may be more adequate.     

Properties of visual evoked potentials to onset of movement on a television screen

In 80 subjects the dependence of movement-onset visual evoked potentials on some measures of stimulation was examined, and these responses were compared with pattern-reversal visual evoked potentials to verify the effectiveness of pattern movement application for visual evoked potential acquisition. Horizontally moving vertical gratings were generated on a television screen. The typical movement-onset reactions were characterized by one marked negative peak only, with a peak time between 140 and 200ms. In all subjects the sufficient stimulus duration for acquisition of movement-onset-related visual evoked potentials was 100ms; in some cases it was only 20ms. Higher velocity (5.6°/s) produced higher amplitudes of movement-onset visual evoked potentials than did the lower velocity (2.8°/s). In 80% of subjects, the more distinct reactions were found in the leads from lateral occipital areas (in 60% from the right hemisphere), with no correlation to handedness of subjects. Unlike pattern-reversal visual evoked potentials, the movement-onset responses tended to be larger to extramacular stimulation (annular target of 5°–9°) than to macular stimulation (circular target of 5° diameter).Abbreviation PREP pattern-reversal visual evoked potentials     

Multiprogrammable pacemakers. Complications. Nursing care

This paper deals with the study of 927 patients of both sexes, with multiprogramable pacemakers implanted during 1987-1988 period, at the "Comandante Manuel Fajardo" Teaching Hospital and the Institute of Cardiology and Cardiovascular Surgery. Complications accounted for 14.9% and the most frequent were, in decreasing order, as follows: sepsis of the pocket (46.7%), hematoma of the pocket, increased threshold and, in a lower percentage, aseptic necrosis (5.7%). Emphasis is made in the role of the nurse in front of a patient with pacemaker and of the different complications presented.     

Cross neutralization of SARS-CoV-2 omicron subvariants after repeated doses of COVID-19 mRNA vaccines

We have measured the humoral response to messenger RNA (mRNA) vaccines in COVID-19 naïve and convalescent individuals. Third doses of mRNA COVID-19 vaccines induced a significant increase in potency and breadth of neutralization against SARS-CoV-2 variants of concern (VoC) including Omicron subvariants BA.1, BA.2, and BA.2.12.1, that were cross-neutralized at comparable levels and less for BA.4/5. This booster effect was especially important in naïve individuals that only after the third dose achieved a level that was comparable with that of vaccinated COVID-19 convalescents except for BA.4/5. Avidity of RBD-binding antibodies was also significantly increased in naïve individuals after the third dose, indicating an association between affinity maturation and cross neutralization of VoC. These results suggest that at least three antigenic stimuli by infection or vaccination with ancestral SARS-CoV-2 sequences are required to induce high avidity cross-neutralizing antibodies. Nevertheless, the circulation of new subvariants such as BA.4/5 with partial resistance to neutralization will have to be closely monitored and eventually consider for future vaccine developments.
