Occupational therapy for multiple sclerosis.

BACKGROUND: Multiple sclerosis (MS) patients are referred to occupational therapy with complaints about fatigue, limb weakness, alteration of upper extremity fine motor coordination, loss of sensation and spasticity that causes limitations in performance of activities of daily living and social participation. The primary purpose of occupational therapy is to enable individuals to participate in self-care, work and leisure activities that they want or need to perform. OBJECTIVES: To determine whether occupational therapy interventions in MS patients improve outcome on functional ability, social participation and/or health related quality of life. SEARCH STRATEGY: Relevant full length articles were identified by electronical searches in Medline, Cinahl, Embase, Amed, Scisearch and The Cochrane MS Group Trials Register. The reference list of identified studies and reviews were examined for additional references. Date of last search: December 2002. SELECTION CRITERIA: Controlled (randomized and non-randomized) and other than controlled studies addressing occupational therapy for MS patients were eligible for inclusion. DATA COLLECTION AND ANALYSIS: The methodological quality of the included trials was independently assessed by two reviewers. Disagreements were resolved by discussion. A list proposed by Van Tulder et al. (Van Tulder 1997) was used to assess the methodological quality. For outcome measures, standardized mean differences were calculated. The results were analysed using a best-evidence synthesis based on type of design, methodological quality and the significant findings of outcome and/or process measures. MAIN RESULTS: Only one randomized clinical trial was identified. Two other included studies were a controlled clinical trial and a study with a pre-post test design. The studies included 271 patients in total. Two studies evaluated an energy-conservation course for groups of patients and one study evaluated a counselling intervention. The results of the energy conservation studies could be biased because of the designs used, the poor methodological quality and the small number of included patients. The high quality RCT on counselling reported non-significant results. REVIEWER'S CONCLUSIONS: On basis of this review no conclusions can be stated whether occupational therapy improves outcome in MS patients. The lack of (randomized controlled) efficacy studies in most intervention categories of OT shows an urgent need for future research in occupational therapy for multiple sclerosis. Initially, a survey of occupational therapy practice for MS patients including the characteristics and needs of these patients is necessary to develop a research agenda for efficacy studies.

[Individualized hemodilution in acute brain infarct using a 20% albumin solution and physiological saline solution]. / Hemodilutie op maat bij het acute herseninfarct met behulp van een 20%-albumine-oplossing en fysiologische zoutoplossing.

OBJECTIVE: To determine the effect of normovolaemic haemodilution in patients after a cerebrovascular accident. DESIGN: Prospective, randomized clinical trial. SETTING: St Lucas Hospital, Amsterdam. METHOD: Normovolaemic haemodilution was achieved by means of bloodletting and administration of a 20% solution of albumin plus crystalline infusion fluids under haemodynamic and rheological monitoring during the acute phase of the cerebral infarction. All patients were subjected to general intensive care and monitoring with a pulmonary artery catheter. This custom-tailored fluid therapy was guided by a pulmonary wedge pressure of 12 mm Hg (SD 3) and a haematocrit (Ht) of 0.32 l/l (SD 0.02). The control group only received individually dosed rehydration with crystalline infusion fluids. Endpoints of the study after 3 months were mortality and dependence/independence concerning everyday functioning. RESULTS: The results in the total haemodilution group and the control group did not differ significantly. However, in the subgroup with normal Ht (< 0.45 l/l; n = 201) there was a significant reduction (p < 0.05) of the mortality after 3 months (27% and 16%, respectively) and an increase of independence at home (35% and 48%, respectively) due to a reduction of the viscosity by means of haemodilution with albumin (a specific viscosity effect in the normovolaemic group). In the control group with raised Ht (dehydration; Ht > or = 0.45 l/l; n = 50) there was a significant decrease (p < 0.005) of the mortality after 3 months (27% and 8%, respectively) and an increase of independence at home (35% and 59%, respectively) compared with the control group with normal Ht without signs of dehydration (Ht < 0.045 l/l; n = 102), due to rehydration exclusively with crystalline infusion fluids (a specific rehydration effect in the dehydrated group). CONCLUSION: In cerebrovascular accident patients haemodilution should be adjusted individually; in normovolaemic patients haemodilution should be carried out with an albumin solution; the higher the Ht, the more rehydration with crystalline infusion fluids is to be carried out.

Penetration of praziquantel into cerebrospinal fluid and cysticerci in human cysticercosis.

Two patients with cysticercosis received praziquantel (PZQ) 75 mg/kg/day orally together with 30 mg prednisone daily for 3 weeks. The first patient presented with grand-mal seizures, a pyramidal tract syndrome and subcutaneous cysticerci, and the other had internal hydrocephalus necessitating drainage. Serial plasma samples were taken after the first dose of PZQ. Lumbar CSF was obtained from the first patient and ventricular CSF from the second. Subcutaneous cysticerci were removed from the first patient. PZQ in the specimens was assayed by GLC. For distribution between plasma and CSF a rate constant of 4.9 h-1 for free PZQ, corresponding to a t1/2 of 8 min or less for the non-protein bound fraction was calculated for Patient 1. In the second patient the distribution was so rapid that the rate constant could not be calculated. The difference in distribution rate might have been due to use of different sampling times or to a time lag in the entry of PZQ between the ventricles and the lumbar sac. The rate constant for distribution of the drug between plasma and parasites was 1.4 h-1, corresponding to a t1/2 of 30 min or less. Thus PZQ penetrates rapidly into the CSF. It enters the parasite more slowly, although still more rapidly than the plasma half-life of PZQ (1-1 1/2 h).
