ABSTRACT
Primary synovial osteochondromatosis (PSOC) is a rare but clinically significant cause of morbidity especially in the male population. Surgery is the primary treatment of choice, but the recurrence rate is reported to be high. Moreover, the presence of widespread loose bodies makes it a cumbersome procedure. The complete removal of the disease is tough at times and results in early recurrence. Radiosynovectomy is an established technique for treating various joint arthropathies. The role of radiosynovectomy in case of PSOC has not yet been explored. This case report described the case of a young male with PSOC of the knee joint who was treated with radiosynovectomy for pain relief. The patient reported complete relief from the pain along with significant improvement in joint mobility. The post-therapy three-phase bone scan also validated the reduction in joint inflammation. The patient was taken for surgical removal of the redundant loose bodies after a significant improvement in the pain and reduction in inflammation. Post-therapy radiation fibrosis of the synovium also helped in the en bloc removal of the disease. The role of radiosynovectomy in PSOC needs to be further explored concerning its potential role as an adjuvant to surgical procedures.

El monitoreo constante del nivel de saturación de oxígeno y la producción de CO2 es de vital importancia para la supervisión del estado respiratorio del paciente. Este artículo presenta el diseño de un sistema de oximetría de pulso y capnografía que tiene como unidad de procesamiento un chip programable de señales mixtas denominado PSoC (Programable-System-On-Chip), el cual incorpora bloques análogos y digitales configurables, permitiendo que la adecuación de las señales suministradas por los sensores y el procesamiento digital de señales se lleve a cabo en el mismo chip. Se realizó una aplicación en Android para la visualización y registro de las señales biomédicas en una base de datos local, compatible con dispositivos móviles con conectividad wifi. El sistema fue verificado usando un simulador de SpO2 (Saturación parcial de oxígeno), que permitió la calibración de frecuencias cardiacas desde 55 BPM (Beats per Minute) a 145 BPM, así como la curva R con valores de 75% a 100% de SpO2. Se encontró que el error de medición de la frecuencia cardiaca es 1,81%, y 1.33% para la SpO2.
Constant monitoring of oxygen saturation level and CO2 production is vital for monitoring the patient's respiratory status. This paper presents the design of a pulse-oximetric and capnographic system, which core consists of a mixed signal programmable chip, PSoC (Programmable-System-On-Chip), which incorporates a whole analog and digital configurable block system, in order to adequate and process the signals from the sensors all in a single chip. An Android application was also developed, which can display biomedical signals in mobile devices with wireless connectivity, as well as to store information from these signals in a local user database. The microsystem was verified using a SpO2 (oxygen partial saturation) simulator, and heart rates of 55 BPM to 145 BPM were calibrated, as well as the R curve with values of 75% to 100% SpO2. The heart rate measurement error found is 1,81% and 1,33% for the SpO2.

Verificou-se que o erro de medição do ritmo cardíaco é 1,81% e 1,33% para o SpO2.
ABSTRACT
OBJECTIVES: While parents who foster children with epilepsy would have considerable parenting difficulties, the parenting stress and sense of competence have not been investigated. We investigated maternal parenting stress, parenting satisfaction and sense of parenting competence in children with seizure disorders, and the associations with seizure-related variables. METHODS: Mothers of 79 children with seizure disorders (41 boys, 38 girls; mean age, 9.9+/-2.3 years) and 79 healthy comparison subjects matched for age and sex were recruited for this study. The Korean version of the Parenting Stress Index (K-PSI-SF) and the Parenting Sense of Competence (K-PSOC) were used to assess parenting stress, parenting satisfaction and parenting efficacy. RESULTS: Mothers of children with seizure disorders showed higher scores on stress related to difficult child and child learning and parenting anxiety compared to mothers of healthy children. In addition, scores on stress related to parental-child interaction and child learning were significantly associated with parental economic status. Scores on stress from parental-child interaction was also correlated with seizure severity, and stress from child learning was correlated with seizure type. Sense of parenting competence and anxiety scores were correlated with paternal educational status, respectively. CONCLUSION: These findings suggest that mothers of children with epilepsy have greater parenting stress and anxiety and social and seizure-associated factors may affect the parenting stress and anxiety.
