Factors Related to Noncompliance in Screening and Tracking Mild Cognitive Impairment Patients in a Single Community

OBJECTIVE: We assessed the cumulative conversion rates (CCR) from minor cognitive impairment (MCI) to dementia among individuals who failed to participate in annual screening for dementia. Additionally, we analyzed the reasons for failing to receive follow-up screening in order to develop better strategies for improving follow-up screening rates. METHODS: We contacted MCI patients who had not visited the Dongdaemun-gu Center for Dementia for annual screening during the year following their registration. We compared the CCR from MCI to dementia in the following two groups: subjects registered as having MCI in the Dongdaemun-gu Center for Dementia database and subjects who failed to revisit the center, but who participated in a screening test for dementia after being contacted. The latter participants completed a questionnaire asking reasons for not previously visiting for follow-up screening. RESULTS: The final diagnoses of the 188 subjects who revisited the center only after contact were 19.1% normal, 64.9% MCI and 16.0% dementia. The final diagnoses of the 449 subjects in the Dongdaemun-gu Center for Dementia database were 25.6% normal, 46.1% MCI and 28.3% dementia. The CCR of the revisit-after-contact group was much lower than anticipated. The leading cause for noncompliance was “no need for tests” at 28.2%, followed by “other reasons” at 23.9%, and “I forgot the appointment date” at 19.7%. CONCLUSION: Considering the low dementia detection rate of the group who revisited only after contact and the reasons they gave for noncompliance, there appears to be a need for ongoing outreach and education regarding the course and prognosis of MCI.

Logros y retos de la colecistectomía laparoscópica en Cuba / Achievements and challenges of the laparoscopic cholecystectomy in Cuba

Objetivo: conocer los resultados de la generalización de la colecistectomía laparoscópica en Cuba. Métodos: se realizó un estudio retrospectivo y descriptivo a través de una encuesta completada por 16 grupos de cirugía de mínimo acceso de hospitales universitarios en 9 provincias del país para definir carácter, conversiones, conducta ante litiasis de la vía biliar, morbilidad y mortalidad perioperatoria. Resultados: se obtuvieron datos relacionados con 56 878 intervenciones realizadas, desde los inicios de la actividad en esos servicios, hasta noviembre de 2007, y se definió carácter, conversiones, conducta ante litiasis de la vía biliar, morbilidad y mortalidad perioperatoria. El acceso laparoscópico se usó en 80,7 por ciento de los casos, electivo en 97,1 por ciento, con índices de conversión de 1,4 por ciento, morbilidad de 0,58 por ciento y mortalidad de 0,10 por ciento. Predominó, ante el hallazgo de litiasis coledociana, el convertir y explorar de forma convencional. Conclusiones: los resultados de la generalización de la colecistectomía laparoscópica en Cuba son excelentes, pero es necesario extender su uso como arsenal en el tratamiento de las complicaciones de la litiasis biliar(AU)

Objective: to know the results from the standardization of the laparoscopic cholecystectomy in Cuba. Methods: a descriptive and retrospective study was conducted be means of a survey completed by 16 groups of minimal access surgery from university hospital in 9 provinces of our country to define the character, conversions, behavior in face of biliary tract lithiasis, perioperative morbidity and mortality. Results: it was possible to obtain data related to 56 878 surgical interventions performed from the onset of activity in these centers up to November, 2007 defining the character, conversions, behavior in face of a biliary tract lithiasis and perioperative morbidity and mortality. The laparoscopic approach was used in the 80,7 percent of cases, elective in the 97,1 percent, with conversion rates of 1,4 percent, morbidity of 0,58 percent and mortality of 0,10 percent. There was predominance of conversion and exploration of conventional for in face of the choledochal lithiasis finding. Conclusions: results of standardization of laparoscopic cholecystectomy in Cuba are excellent, but it is necessary to extend its use as a tool in the treatment of the biliary lithiasis complications(AU)

PREPARATION AND APPLICATION OF BCG-PPD / 微生物学通报

BCG Purified Protein Derivative (BCG-PPD)was isolated and purified from BCG Culture filtrate by trichloroacetic acid and ammonium sulfate methods. The purity of BCG-PPD was Similar to PPD-S(international standard) and PPD-C(China), but more than that of PPD-CT68 (Canada)and PPD-RT23(Danish). The Delayed-Type Hyperseusitivity(DTH) to BCG-PPD was more sensitivity than other PPD on BCG vaccinated guinea pigs, but less sensitivity than other PPD on Mycobacterium tuberculosis infected guinea pigs. The conversion rate and induration diameter to BCG-PPD was higher than PPD in 333 of 12 weeks after BCG vaccination newborns, but lower than that of other PPD in 97 tuberculosis patients. It was shown that DTH reaction to PPD was more sensitivity in Mycobacteria homogeneous strain vaccinated individual than Mycobacteria heterogeneous strain vaccinated individual. It was demonstrated that BCG-PPD was better than other PPD on observation conversion rates and induration diameter of BCG vaccinated individual. It maybe help to identification BCG vaccinated or tuberculosis infected with DTH of BCG-PPD and PPD in same individual.
