Treatment of essential tremor with the barbiturate T2000 (1,3-dimethoxymethyl-5,5-diphenyl-barbituric acid).

The effect of the barbiturate T2000 (1,3-dimethoxymethyl-5,5-diphenyl-barbituric acid; DMMDPB) on essential tremor, given in twice daily doses of 400 and 300 mg, was assessed in two brief, randomized, placebo-controlled, parallel-group, double-blinded, single-center trials in 12 and 22 patients, respectively. These trials represent the first clinical use of T2000 for a specific indication. The primary endpoint was the change in the mean scores of the treated and control groups based on the Fahn-Tolosa-Marin tremor scale. In the first study of 12 patients treated with 400 mg or placebo twice daily for 14 days, the mean change from baseline at day 14 was 19.3 (P < 0.0001) in the treated group and 9.0 (P = 0.0121) in the control group. Using a two-factor mixed ANOVA model to evaluate within group and between group changes, the effect of T2000 was significantly different from that of the placebo group (P = 0.03). In the second study of 22 patients treated with 300 mg of T2000 or placebo twice daily for 20 days, statistically significant changes were seen in treated patients compared to baseline, but the ANOVA model did not demonstrate a significant treatment effect of T2000 compared to placebo. When the treated groups from each study are compared, the 800-mg daily group is significantly different from the 600-mg daily group (P = 0.02). Some treated patients in each study, but no placebo patients, experienced marked improvement. These results support further evaluation of T2000 in the treatment of essential tremor.     

Project 2000: perceptions of the philosophy and practice of nursing: shifting perceptions—a new practitioner?

This is the first of two papers which address aspects of the findings of a large scale study commissioned by the English National Board which set out to examine the impact of Project 2000 on perceptions of the philosophy and practice of nursing. The findings presented here suggest that there have been fundamental shifts in perceptions of the nature and discipline of nursing. Students and diplomates of the course perceive themselves as knowledgeable doers, with their practice well grounded in theory and research. They value the interpersonal skills teaching and place the patient firmly at the centre of care delivery, viewing the patient holistically and being prepared to be fierce patient advocates where necessary. It is difficult to determine the extent to which these shifts can be attributed to the Project 2000 course, although the Project 2000 approach to education appears to be an important factor.     

Posterior instability near extension is related to clinical disability in isolated posterior cruciate ligament deficient patients

The purpose of this study is to evaluate the relationship between the magnitude of knee laxity and posterior instability at different knee flexion angles and clinical disability in isolated posterior cruciate ligament (PCL) deficient patients. Knee laxity at 20° and 70° of knee flexion were evaluated using KT-2000 arthrometer, and the posterior instability at 20°, 45° and 90° of flexion were evaluated using stress radiography. We assessed the differences in the knee laxity and the tibial translation between isolated PCL deficient knees and normal knees, and between the patients with giving-way during activities of daily living (ADL) and without giving-way. There were statistical differences in the knee laxity and the tibial translation at all knee flexion angles between the PCL deficient knees and normal knees. The magnitude of the knee laxity at 20° of flexion measured with KT-2000 arthrometer was significantly larger in the patients with giving-way than those in the patients without giving-way although there was no significant difference in the tibial translation at 70° between the two groups. The tibial translation in both medial and lateral compartments at 20° and 45° measured with stress radiography were significantly larger in the patients with giving-way than those in the patients without giving-way although there was not significant difference at 90° between the two groups. These results suggested that the magnitude of the knee laxity and the posterior tibial translation at shallow knee flexion angles would be related to giving-way during ADL in isolated PCL deficient patients.     

The implications of Project 2000 and the formation of links with higher education for the professional and academic needs of nurse teachers in the United Kingdom

A national study was conducted between 1991 and 1994 to explore and describe the changing role of the nurse teacher following the introduction of Project 2000 pre-registration nursing courses. Multiple methods were used to collect data from a wide variety of respondents (nurse teachers, midwife teachers, clinical nurses, health service managers and higher education lecturers). This paper presents the findings relating to the impact of Project 2000 and the move into higher education on the continuing educational needs of nurse teachers. Views on college strategies for staff development, the changing nature of teachers'academic and professional development needs and the problems of the conflicting demands experienced are reported. The research highlights the need for clinical credibility to be clearly defined in relation to nurse teachers and for educational institutions to place more emphasis on teachers'clinical development if the rhetoric of policy is to become a reality.     

Anatomy of the arterial vascularization of the lips

Summary The findings from 12 dissections of previously injected facial masks, 8 dissections of the face following intrarterial injection of a red solution of Latex Neoprene, and a corrosion cast specimen allowed us to study the arterial supply of the lips. The arterial supply of the upper lip arises mainly from the superior labial arteries, but also from the subseptal arteries and from the subalar arteries. There is a figure of 8 shaped anastomotic system between these arteries lying on the upper lip. The arterial supply of the lower lip arises from the inferior labial arteries and from branches of the mental artery. A constant inferior labial arterial network was shown at the level of the lower lip arising in a fifth of cases from a T-shaped inferior labial artery. All these recent anatomic findings help us to improve our understanding of plastic surgery of the lips.

Vascularisation artérielle des lèvres

Résumé Douze dissections de masques faciaux préalablement injectés à la gélatine minium, huit dissections de face après injection artérielle par une solution de latex néoprène rouge, et une injectioncorrosion a permis l'étude de la vascularisation artérielle labiale. La lèvre supérieure reçoit sa vascularisation artérielle des artères labiales supérieures principalement, mais aussi des artères sous-narinaires branches des artères faciales, et des artères de la sous-cloison. Il existe un système d'anastomose fréquent entre les trois artères décrivant un aspect de 8 de chiffre couché au niveau de la lèvre supérieure. La lèvre inférieure est vascularisée par les artères labiales inférieures et par des branches de l'artère mentonnière ; il existe de manière constante au niveau de la lèvre inférieure une arche artérielle labiale inférieure provenant une fois sur cinq d'une artère labiales inférieure en T unique. Toute ces données anatomiques récentes permettent d'envisager dans de meilleures conditions la chirurgie réparatrice des lèvres.

     

Clinical use of biofeedback in rehabilitation

Clinical electromyographic (EMG) biofeedback was an outgrowth of diagnostic electromyography and research on the fine control of motor units. In rehabilitation, EMG biofeedback has gained a firm place in the treatment of upper motor neuron lesions, particularly in retraining muscles and inducing relaxation of spastic muscles of stroke patients. In cerebral palsy and musculoskeletal disturbances, additional feedback transducers (e.g., electrogoniometers, pressure-sensitive and position-sensing devices) are gaining wider use. Spasmodic torticollis has proved to be particularly suitable for behavioral methods of treatment, including EMG feedback.

Local interferon therapy for lip carcinoma

In a prospective non-randomized study 21 patients with lower lip squamous cell carcinoma were treated with human natural leukocyte interferon (HNLI). The response rate was measured by a size reduction of more than 25% and was 81%. A complete response rate was considered to be a cure according to histopathological and clinical findings and was 48%. The response rate of six lower lip squamous cell carcinoma cases treated with recombinant interferon alpha 2c was 67% and the complete response rate was 17%. Three patients with basal cell carcinoma of the upper lip were also treated with HNLI. All three patients were cured, as determined by histopathological and clinical findings. These findings indicate that interferon can be a useful alternative therapy for lip carcinoma either with or without surgery.     

Virtual Changes of the Shape of the Lips

Many of the unsatisfactory results in cosmetic surgery are due not to the technique employed itself but to the virtual changes that our work has imposed in other areas. These changes are especially evident in the face, due to the small dimensions of its organs. The surgeon should do a thorough evaluation of the area to be treated prior to the surgery and make her/him notice not only the usual existing asymmetries, but also the modifications which probably will be noticed in the neighboring parts after surgery, to avoid later problems. The surgeon will discover then the many irregularities a patient may have, which have not been noticed by the patient before. These, if not detected in time, are weapons that may act as a boomerang against the surgeon later.
