Efficacy of modified constraint-induced movement therapy in acute stroke.

BACKGROUND: Modified constraint induced movement therapy (m-CIMT) discourages the use of the unaffected extremity and encourages the active use of the hemiplegic arm in order to restore the motor function. AIM: The aim was to assess the efficacy of m-CIMT on functional recovery of upper extremity (UE) in acute stroke patients, as compared to conventional rehabilitation therapy. DESIGN: This is a prospective comparative study. SETTING: This study included sixty patients with acute stroke recruited from neurology department. METHODS: This study included sixty acute stroke patients. Inclusion criteria were: patients within two weeks from the onset of stroke, persistent hemiparesis leading to impaired upper extremity function, evidence of preserved cognitive function, and a minimum of 10 degrees of active finger extension and 20 degrees of active wrist extension. Exclusion criteria were: intra-cerebral hemorrhage, previous stroke on the same side, presence of neglect or a degree of aphasia impeding understanding of instructions, and conditions that limit the use of the upper limb before the stroke. Patients were assessed by Fugl-Meyer motor assessment (FMA), action research arm test (ARAT) and motor evoked potentials (MEPs), recorded from the abductor pollicis brevis (APB) of the affected hand. The clinical and neurophysiological tests were performed pre and postrehabilitation. The patients were divided into two groups: Conventional rehabilitation program group (CRP) included 30 patients who were given a conventional rehabilitation program for two weeks. CIMT group included 30 patients who were subjected to modified CIMT for two consecutive weeks. Total treatment time was the same in both groups. RESULTS: CRP group showed a non-significant improvement in FMA and ARAT. CIMT group showed a significant improvement in clinical scores on all tests (P<0.05). When comparing both groups using FMA and ARAT tests pre- and post- therapy, a significant difference (P<0.05) was found between both groups with CIMT group showing greater improvement. When comparing MEPs in CRP group, pre and postrehabilitation, a non-significant improvement was found for resting motor threshold (RMT), central motor conduction time (CMCT) and amplitude of MEPs. In contrast, each of the MEP parameters exhibited a significant improvement in CIMT group (P<0.05). CONCLUSION: In contrast to conventional rehabilitation therapy, modified CIMT revealed a significant functional and MEP improvement in acute stroke patients indicating that m-CIMT might be a more efficient treatment strategy. CLINICAL REHABILITATION IMPACT: It is advised to use modified constraint movement therapy in rehabilitation of cerebrovascular stroke during acute stage.

The clinical and cost effectiveness of bee honey dressing in the treatment of diabetic foot ulcers.

Honey is known, since antiquity, as an effective wound dressing. Emergence of resistant strains and the financial burden of modern dressings, have revived honey as cost-effective dressing particularly in developing countries. Its suitability for all stages of wound healing suggests its clinical effectiveness in diabetic foot wound infections. Thirty infected diabetic foot wounds were randomly selected from patients presenting to Surgery Department, Suez Canal University Hospital, Ismailia, Egypt. Honey dressing was applied to wounds for 3 months till healing, grafting or failure of treatment. Changes in grade and stage of wounds, using University of Texas Diabetic Wound Classification, as well as surface area were recorded weekly. Bacterial load was determined before and after honey dressing. Complete healing was significantly achieved in 43.3% of ulcers. Decrease in size and healthy granulation was significantly observed in another 43.3% of patients. Bacterial load of all ulcers was significantly reduced after the first week of honey dressing. Failure of treatment was observed in 6.7% of ulcers. This study proves that commercial clover honey is a clinical and cost-effective dressing for diabetic wound in developing countries. It is omnipresence and concordance with cultural beliefs makes it a typical environmentally based method for treating these conditions.

T-lymphocyte subsets and thymic size in malnourished infants in Egypt: a hospital-based study.

Thymus size was assessed ultrasonographically and correlated to the percentage of CD4 and CD8 T-lymphocytes in peripheral blood in 32 infants with protein-energy malnutrition (PEM) and compared with 14 healthy control infants. The study revealed thymus atrophy in patients with PEM, especially the oedematous type, accompanied by changes in the peripheral lymphocyte subsets. These changes were reversible after nutritional rehabilitation. However, they may affect the immune status of PEM patients and may require a longer duration of nutrition rehabilitation than required for recovery of anthropometric measures. We recommend proper assessment of the immune functions of PEM patients during nutritional rehabilitation until full recovery.
