RESUMO

INTRODUCTION: Lewy body disorders such as Parkinson's disease (PD) and Lewy body dementia (LBD) are associated with cardiac sympathetic denervation, which can be visualized on 123I-MIBG scintigraphy. Our objectives were to study the diagnostic value of this technique in Lewy body disorders and its relationship with PD clinical variables. PATIENTS AND METHODS: We studied 90 patients: 51 with PD, 19 with LBD, 9 with multiple system atrophy (MSA) and 11 controls. Scintigraphy images were qualitatively evaluated and early and delayed heart-to-mediastinum ratios (HMR) were calculated. The main confounding factors (ischemic heart disease, diabetes, hypertension and drugs) were controlled by multivariate linear regression analysis. We investigated correlations between scintigraphy variables and PD variables. RESULTS: The delayed HMR, which showed better discriminative ability was 2.03 +/- 0.32 in controls, 1.37 +/- 0.30 in PD (p<0.001 vs controls), 1.47+/-0.45 in LBD (p=0.001 vs controls) and 1.69+/-0.28 in MSA (p=0.02 vs controls; p=0.004 vs PD). This ratio was influenced by PD/LBD diagnosis (beta= -0.638; p<0.001) and to a lesser degree, by ischemic heart disease (beta= -0.244; p=0.028). Optimal cut-off value between PD/LBD and controls was 1.71 (83% sensitivity and 82% specificity). Within the PD group, those with a family history of PD/LB showed higher delayed HMR values (1.65+/-0.34 vs 1.30+/-0.24 without history; p<0.001) and proportion with normal scintigraphy (56% vs 5%; p=0.001). CONCLUSIONS: Cardiac 123I-MIBG scintigraphy is useful in the diagnosis of Lewy body disorders, although its value in PD is conditioned by having a family history of PD.

RESUMO

INTRODUCTION: Bilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) or globus pallidus internus (GPi) have demonstrated efficacy in advanced Parkinson's disease (PD). We aimed to assess the clinical utility of these procedures in terms of the quality of life, and to determine the pre and postsurgical characteristics related to the outcome. METHOD: A prospective study was conducted on a cohort of 20 patients with advanced PD who underwent bilateral DBS: 14 in STN and 6 in GPi. They were assessed according to the CAPSIT-PD protocol before and after surgery, with a mean follow-up of 9 and 11 months, respectively. The main outcome variables were change in the UPDRS III score in off efficacy and the PDQ-39 quality of life questionnaire score (clinical utility). RESULTS: The STN group improved their UPDRS III in off by a mean of 35% (p = 0.001) and their PDQ-39 by 21% (p = 0.026). The GPi group improved their UPDRS III in off by 21% (p = 0.028) and their PDQ-39 by 37% (p = 0.116). The presurgical levodopa-equivalent dose was a positive predictor of the efficacy and clinical utility of STN DBS and a negative predictor of the efficacy of GPi DBS. In both groups, the clinical utility was determined by improvement in functional disability in off scales. CONCLUSIONS: Bilateral DBS demonstrated middle-term efficacy and clinical utility in the treatment of advanced PD. The presurgical levodopa-equivalent dose was a predictor of the efficacy and clinical utility of DBS.

RESUMO

A 75-year-old woman was admitted to our hospital with persistent fever, productive cough and systemic symptoms of two months' duration. A chest film showed bilateral infiltration in the form of subpleural plaques with multiple satellite nodules in both lung fields. The biopsy specimens taken by thoracoscopy were compatible with inflammatory pulmonary pseudotumor. Lung resection was ruled out because the lesions were bilateral and corticosteroid treatment was instated. The clinical and radiologic response was excellent and the patient was asymptomatic after 30 months of low-dose corticoid therapy.

RESUMO

This paper reports the results of a 12-month implementation study documenting the process of integrating the Lactational Amenorrhea Method (LAM) into a multiple-method family planning service-delivery organization, the Céntro Médico de Orientación y Planificación Familiar (CEMOPLAF), in Ecuador. LAM was introduced as a family planning option in four CEMOPLAF clinics. LAM was accepted by 133 breastfeeding women during the program's first five months, representing about one-third of postpartum clients. Seventy-three percent of LAM acceptors were new to any family planning method. Follow-up interviews with a systematic sample of 67 LAM users revealed that the method was generally used correctly. Three pregnancies were reported, none by women who were following LAM as recommended. Service providers' knowledge of LAM resulted in earlier IUD insertions among breastfeeding women. Relationships with other maternal and child health organizations and programs were also established.

PIP: The aim of this inquiry was to describe the planning and process of integration of the Lactational Amenorrhea Method (LAM), as a viable contraceptive option, into an existing family planning service network. LAM was introduced as a demonstration project in 1991 in 4 out of 20 available clinics nationwide operated by the private, nonprofit Centro Medico de Orientacio y Planificacion. Study sites included Quito in an urban mountainous area, Latacunga in a mixed urban/rural mountainous area, Cajabamba in an isolated area with indigenous populations, and Santo Domingo in a mixed urban/rural coastal area. A needs assessment of clients, staff, and organizational information system factors was conducted 4 months prior to introducing LAM into the pilot clinics. Organizational materials were prepared for clients, and a staff training program was implemented. Baseline information was obtained from 58 clients and 24 staff on the prevailing knowledge, attitudes, and practices of breast feeding and contraception. The educational materials included a wall chart on breast feeding promotion, a wall poster on contraception including LAM, a 12 page booklet for LAM clients, and a desk-size flip chart for one-to-one instruction. Record keeping was improved. LAM was introduced to all mothers with infants 6 months old, who were fully or nearly fully breast feeding and were amenorrheic, and identified by intake staff. Follow-up was after 3 months, unless there was a change in desires or a change in the LAM requirements. After 6 months of implementation, a qualitative evaluation was made. 50% of acceptors were interviewed (67, of which 23 were still using LAM). The results showed that 73% used LAM as their first ever contraceptive method. Compliance with follow-up and LAM instructions varied with each clinic. 87% of users and 67% of Quechua users expressed satisfaction with LAM. A number of observations were made about clinic operations. A refined training model was developed, and there was consensus that the 12-page booklet was the most useful. A well child program was integrated into the LAM program. A surprise finding was the low use among rural traditional ethnic groups. LAM is being included in outreach efforts and the expertise passed along to other health programs. The Pearl pregnancy index was 6.8%, which was comparable to other temporary methods in Andean countries.

RESUMO

A census, uniform screening questionnaire, and simple screening neurologic examination were administered in a door-to-door survey to residents of Quiroga, Ecuador, a rural community in the Andes Mountains. The screening procedures had been pretested to assure a high level of sensitivity for detecting children and adults with major neurologic disease. A total of 1,113 participated in the study. Of these, 399 had responses or findings suggesting the presence of neurologic disease. These individuals were then examined by a neurologist, who used fixed diagnostic criteria. The prevalence ratios (per 1,000) for the most common neurologic conditions identified in this survey are: recurrent/persistent severe headache = 68.3, and epilepsy = 17.1.
