Problems with a ‘target’ approach to access in primary care: a qualitative study

We report an analysis of the qualitative phase of a study of patients' and carers' views of primary care services, focusing on their experiences of access to face-to-face general practitioner (GP) consultations during the period when new access policies were being implemented. Practices interpreted the new policy in various ways; restricted interpretations, including restriction of access to telephone booking, could cause distress to patients. Patients and carers welcomed flexible interpretations of the policy that offered choice, such as a choice of GP, or of booking in advance.     

转译神经科学与焦虑障碍

在20世纪后期,将精神疾病的基础及临床前研究“转译”(translated)到临床相关概念从而引导临床研究的方法已经成为可能。基础神经科学实验的大量成果、大脑分子生物学研究技术的进步及日益精湛的神经影像技术引进到人类和动物研究使得将转译研究(translationalresearch)用于精神病学具有令人振奋的前景。起初,焦虑障碍因为有能极好地反映恐惧的动物模型以及具有广泛性特征,似乎是转译神经科学在精神障碍中应用的典范。然而,关于恐惧与焦虑之间的关系还存在着大量的争论。许多人认为它们是不同的概念:恐惧是对真实危险的自动反应,而焦虑则为…     

Relaxation Therapy and Compliance in the Treatment of Adolescent Headache

SYNOPSIS
Few controlled studies have examined the effectiveness of relaxation therapy for the treatment of adolescent headaches. In this study, ten chronic headache sufferers (migraine or muscle contraction), ranging in age from 12 to 17 years (M = 13.5 SD = 1.3), were sequentially assigned to either a relaxation therapy or waiting-list control group. Following treatment, subjects in the treatment group demonstrated significantly lower Headache Index scores than subjects in the control group (U = 0, p £ .004). Group differences in Headache Free Days, Peak Headache Rating, and Medication Index scores were not significant; differences in Medication Index scores approached significance at U = 3, p £ .03. Objective compliance to treatment data indicated subjects overreported their actual practice time, on average, by 70%. Results and implications for future research are discussed.     

Inadvertent removal of foreign body via a flexible fiberoptic bronchoscope in a 4-year-old boy

We report the case of a 4-year-old child with an atypical presentation of an aspirated unwitnessed foreign body in the airway. During an attempt to obtain a biopsy of what appeared to be a mucosal growth, the foreign body was removed. This may be the first report of foreign body removal in a child this young, using a flexible fiberoptic bronchoscope. Pediatr Pulmonol. 1994; 18:51–52. © 1994 Wiley-Liss. Inc.     

Neonatal Scabies Treated With Permethrin 5% Cream

Abstract: Scabies in neonates and infants has a clinical pattern that may be easily misdiagnosed. The eruption is generalized, including involvement of the head, neck, face, palms, and soles, with an early tendency to pustule formation. Other lesions include papules, vesicles, and burrows, which may be obliterated by secondary lesions. A confusing clinical picture resulted in a delay in diagnosing scabies in a 23-day-old infant who was successfully treated with permethrin 5% cream.     

Piperacillin-Tazobactam Pharmacokinetics in Patients With Intraabdominal Infections

Study Objective . To determine the appropriate compartmental and noncompartmental pharmacokinetic parameters for intravenous piperacillin and tazobactam. Design . Sequential selection of patients entered into a randomized, open-label clinical efficacy trial. Setting . Los Angeles County-University of Southern California Medical Center. Participants . Sequential sample of 18 patients admitted for intraabdominal infections and consented into a comparative antibiotic trial. Interventions . Patients received piperacillin 4 g plus tazobactam 500 mg by intravenous intermittent infusion every 8 hours. Measurements and Main Results . The estimated noncompartmental pharmacokinetic parameters (mean ± SD) for piperacillin and tazobactam, respectively, were as follows: maximum concentration in plasma 218.7 ± 48.9 μg/ml and 27.8 ± 9.1 μg/ml; half-life 1.07 ± 0.22 hours and 1.00 ± 0.27 hours; elimination rate constant 0.67 ± 0.13 hr⁻¹ and 0.73 ± 0.18 hr⁻¹; area under the concentration-time curve from zero hour to infinity 288.5 ± 71.25 mg·hr/L and 36.3 ± 9.55 mg·hr/L; total plasma clearance 14.75 ± 3.93 L/hour and 14.78 ± 4.39 L/hour; renal clearance 5.69 ± 1.94 L/hour and 7.85 ± 3.37 L/hour; volume of distribution at steady state 21.00 ± 4.18 L and 22.47 ± 8.27 L; and mean residence time 1.72 ± 0.29 hours and 1.79 ± 0.35 hours. Conclusion . Our findings were similar to those in other surgical patient models. The two-compartmental model best described piperacillin and tazobactam disposition in our patients. Bayesian analyses of the two-compartment models of piperacillin and tazobactam were able to predict trough, peak, and 2-hour postadministration levels without bias.
