Abstract
Skeletal muscle samples from 38 draft horse-related animals 1-23 years of age were evaluated for evidence of aggregates of glycogen and complex polysaccharide characteristic of equine polysaccharide storage myopathy (EPSSM). Cardiac muscle from 12 of these horses was also examined. Antemortem serum levels of creatine kinase (CK) and aspartate aminotransferase (AST) from 9 horses with EPSSM and 5 horses without EPSSM were compared. Skeletal muscle from 17 horses contained inclusions of periodic acid-Schiff (PAS)-positive, amylase-resistant complex polysaccharide. Similar inclusions were also present in the cardiac muscle of 1 horse. A vacuolar myopathy with aggregates of PAS-positive, amylase-sensitive glycogen was seen in 8 other horses, and these findings are also considered diagnostic for EPSSM. Antemortem serum activities of CK and AST were often higher in EPSSM horses than in horses without EPSSM. Using the presence of amylase-resistant complex polysaccharide as the criterion for diagnosis of EPSSM, the incidence in this population was 45%. Inclusion of horses with aggregates of glycogen but no amylase-resistant complex polysaccharide as representative of the range of pathologic findings in horses with EPSSM resulted in a 66% incidence in this population.

Abstract
PURPOSE Fluorouracil (5-FU) given as a weekly, high-dose 24-hour infusion is active and tolerable. We evaluated an oral regimen of eniluracil (which inactivates dihydropyrimidine dehydrogenase [DPD]), 5-FU, and leucovorin to simulate this schedule. PATIENTS AND METHODS Patients received a single 24-hour infusion of 5-FU (2,300 mg/m(2) on day 2) with leucovorin (15 mg orally [PO] bid on days 1 through 3) to provide reference pharmacokinetic data. Two weeks later, patients began treatment with eniluracil (20 mg) and leucovorin (15 mg) (PO bid on days 1 through 3) and 5-FU (10 to 15 mg/m(2) PO bid on day 2). RESULTS Dose-limiting toxicity (diarrhea, neutropenia, and fatigue) was seen with 5-FU 15 mg/m(2) PO bid on day 2 given weekly for either 6 of 8 weeks or 3 of 4 weeks, whereas five of seven patients tolerated 5-FU 10 mg/m(2) PO bid given weekly for 3 of 4 weeks. Eniluracil led to a 35-fold reduction in 5-FU clearance. Fluoro-beta-alanine, a 5-FU catabolite, was not detected in plasma during oral 5-FU-eniluracil therapy. DPD activity was markedly suppressed in all patients during eniluracil therapy; the inactivation persisted after the last eniluracil dose; percentages of baseline values were 1.8% on day 5, 4.5% on day 12, and 23.6% on day 19. CONCLUSION The recommended oral dosage of 5-FU (10 mg/m(2) PO bid) given with eniluracil and leucovorin is approximately 115-fold lower than the reference dosage for 24-hour infusional 5-FU. This difference is greater than expected given the reduction in 5-FU clearance. DPD inactivation persisted for several weeks after completion of eniluracil therapy.

Abstract
BACKGROUND Photodynamic therapy (PDT) is a new modality involving the administration of a photosensitizer, or photosensitizer precursor, followed by its activation with light to generate a therapeutic effect. 5-Aminolaevulinic acid (ALA) is a photosensitizer precursor that is transformed by cells into protoporphyrin IX (PpIX), which can in turn be activated by red light. OBJECTIVES To investigate the effect of PDT in alopecia areata (AA). METHODS In six patients with extensive AA, topical ALA lotion at 5%, 10% and 20% as well as the vehicle lotion alone were applied separately to different scalp areas, followed 3 h later by exposure to red light at each treatment session. RESULTS No significant hair growth was observed after 20 twice-weekly treatment sessions. A significant increase in erythema and pigmentation was observed for the three concentrations of ALA lotion vs. the vehicle, implying that a phototoxic PDT effect was achieved in the skin. In vivo fluorescence spectroscopy in one patient showed an increase in red PpIX fluorescence 3 h after ALA application followed by a decrease after light exposure. On fluorescence microscopy, bright red fluorescence was present in the epidermis and sebaceous glands, but not in the inflammatory infiltrate surrounding the hair follicle following ALA application. CONCLUSIONS PDT was ineffective in the treatment of AA.

Abstract
Topical immunotherapy with diphencyprone (DPCP) for the treatment of severe alopecia areata has been used since 1983 and is felt to be the treatment of choice by many dermatologists. Although there have been no major side effects reported since its initial use, there remain some unknowns regarding its safety. Because DPCP has at least a 40% success rate for cosmetically acceptable regrowth in extensive alopecia areata, its availability is an important matter for patients with alopecia areata.

Abstract
Proliferative enteropathy (PE) is a transmissible enteric disease caused by Lawsonia intracellularis. An outbreak of equine PE was diagnosed in foals from 3 breeding farms. Most foals had been weaned prior to the appearance of clinical signs, which included depression, rapid and marked weight loss, subcutaneous oedema, diarrhoea and colic. Poor body condition with a rough haircoat and a potbellied appearance were common findings in affected foals. Respiratory tract infection, dermatitis and intestinal parasitism were also found in some foals. Haematological and plasma biochemical abnormalities included hypoproteinaemia, transient leucocytosis, anaemia and increased serum creatinine kinase concentration. Postmortem diagnosis of PE was confirmed on 4 foals based on the presence of characteristic intracellular bacteria within the apical cytoplasm of proliferating crypt epithelial cells of the intestinal mucosa, using silver stains, and by results of PCR analysis and immunohistochemistry. Antemortem diagnosis of equine PE was based on the clinical signs, hypoproteinaemia and the exclusion of common enteric infections. Faecal PCR analysis was positive for the presence of L. intracellularis in 6 of 18 foals tested while the serum of all 7 foals with PE serologically evaluated had antibodies against L. intracellularis. Most foals were treated with erythromycin estolate alone or combined with rifampin for a minimum of 21 days. Additional symptomatic treatments were administered when indicated. All but one foal treated with erythromycin survived the infection. This study indicates that equine PE should be included in the differential diagnosis of outbreaks of rapid weight loss, diarrhoea, colic and hypoproteinaemia in weanling foals.

Abstract
OBJECTIVE To describe an organized diagnostic approach for both nonscarring and scarring alopecias to help family physicians establish an accurate in-office diagnosis. To explain when ancillary laboratory workup is necessary to confirm the diagnosis. QUALITY OF EVIDENCE Current diagnostic and therapeutic interventions for hair loss are based on randomized controlled studies, uncontrolled studies, and case series. MEDLINE was searched from January 1966 to December 1998 with the MeSH words alopecia, hair, and alopecia areata. Articles were selected on the basis of experimental design, with priority given to the most current large multicentre controlled studies. Overall global evidence for therapeutic intervention for hair loss is quite strong. MAIN MESSAGE The most common forms of nonscarring alopecias are androgenic alopecia, telogen effluvium, and alopecia areata. Other disorders include trichotillomania, traction alopecia, tinea capitis, and hair shaft abnormalities. Scarring alopecia is caused by trauma, infections, discoid lupus erythematosus, or lichen planus. Key to establishing an accurate diagnosis is a detailed history, including medication use, systemic illnesses, endocrine dysfunction, hair-care practices, and family history. All hair-bearing sites should be examined. A 4-mm punch biopsy of the scalp is useful, particularly to diagnose scarring alopecias. Once a diagnosis has been established, specific therapy can be initiated. CONCLUSIONS Diagnosis and management of hair loss is an interesting challenge for family physicians. An organized approach to recognizing characteristic differential features of hair loss disorders is key to diagnosis and management.

Abstract
Despite significant clinical and research efforts aimed at recognizing and managing "difficult" patients, such patients remain a frustrating experience for many clinicians. This is especially true for primary care residents, who are required to see a significant volume of patients with diverse and complex problems, but who may not have adequate training and life experience to enable them to deal with problematic doctor-patient situations. Literature--short stories, poems, and patient narratives--is a little-explored educational tool to help residents in understanding and working with difficult patients. In this report, the authors examine the mechanics of using literature to teach about difficult patients, including structuring the learning environment, establishing learning objectives, identifying teaching resources and appropriate pedagogic methods, and incorporating creative writing assignments. They also present an illustrative progression of a typical literature-based teaching session about a difficult patient.

Abstract
Microarousals (MAs) are brief transient events that occur during normal sleep in humans and with increased frequency in disordered sleep, especially in association with sleep apnoea. In a feline model, we discovered transient cardiorespiratory events during nonrapid eye movement (NREM) sleep that exhibited consistent features with similarities to human MAs. It was observed that MAs have two distinct phases. Phase I (MAI) is characterized by an abrupt increase in electromyogram (EMG) amplitude (> 50%), increased electrooculogram (EOG) activity and accelerated frequency of hippocampal electroencephalographic (EEG) activity. MAI lasts 4.1 +/- 0.3 s. Phase II (MAII), lasting 9.8 +/- 0.8 s, is characterized by high frequency EEG activity, but EMG, EOG and hippocampal activity remain at baseline levels. Mean inspiratory rate begins to increase 15 s before the onset of the MA, followed 10 s later by the increase in mean heart rate. Mean respiratory rate decreases sharply through MAII, and returns to baseline levels 15 s after the MA. During MAII mean heart rate decreases quickly; there is increased respiratory irregularity, followed by a prolonged ventilatory overshoot. The abrupt shift in heart rate is coincident with the change in breath timing seen during MAII. Heart rate returns to baseline levels 10 s following the MA. Integrating our findings with those described previously in humans, we propose that MAs may serve as a homeostatic mechanism which is designed to restore cardiorespiratory function allowing the continuity of sleep.

Abstract
BACKGROUND The national evaluation of general practitioner (GP) commissioning pilots was commissioned by the Department of Health in 1997 as part of its Policy Research Programme. It was conducted by the Health Services Management Centre at the University of Birmingham. AIM To monitor the development of the 40 national pilot sites, identify the factors that inhibited or facilitated progress, and consider the implications for the implementation and development of primary care groups (PCGs). METHOD Semi-structured face-to-face interviews with GPs, health authority (HA) managers, and pilot managers from each of the 40 pilot sites (141 interviews in total) and focus group discussions with nurses, social services officers, and community health council officers in the 40 sites. RESULTS Stakeholders reported the key achievements of the pilots during their first six months as being improved collaboration between GPs, the establishment of organisational arrangements, and work towards managing the group prescribing budget. Obstacles for the groups included changes to government policy regarding primary care, the workload involved for clinical staff, the pilots' relationship with the local HA, and problems with information management and technology (IM&T). A more detailed analysis of the pilots' management arrangements, prescribing work, IM&T support, and stakeholder involvement points to a set of lessons for emerging PCGs. CONCLUSIONS In their early stages of development, PCGs are likely to focus on issues of structure and process. Prescribing will be an area receiving particular attention, prefiguring some of the challenges of clinical governance in primary care. IM&T will prove to be more problematic than first assumed. The involvement of a wider range of stakeholders will be addressed by primary care groups, particularly in relation to GPs and nurses.

Abstract
Alopecia areata (AA) is a nonscarring hair loss condition. Among the many factors under investigation in the pathogenesis of AA, the main areas of concentration have been genetic constitution as well as nonspecific immune and organ-specific autoimmune reactions. Treatment with intralesional corticosteroid injections for localized patchy AA and topical immunotherapy for extensive AA have proven successful in the majority of patients, although all treatments are palliative and do not change the prognosis of the disease.

Abstract
Androgenetic alopecia is by far the most common cause of hair loss. It affects approximately 50% of men by the age of 50 and 20 to 53% of women by the age 50. Although it is a medically benign condition, it is a significant psychosocial issue for many patients. Various different treatment options are now available for androgenetic alopecia. The best treatment option for women with androgenetic alopecia Ludwig stage I and II is minoxidil 5% solution. If it is not effective after 1 year, antiandrogens can be tried, but there are no large studies showing their efficacy and they have considerable adverse effects. Also, for patients with alopecia that is unresponsive to treatment or with Ludwig stage III, hair transplantation can be offered if the occipital donor area is sufficient. For men, we always offer minoxidil or finasteride therapy and leave the choice of therapy to the patient. Some patients may prefer a systemic agent, whereas others may favor a topical agent. If the condition is not stabilized after 1 year or if the patient wants greater hair density, hair transplantation can be discussed. There have been tremendous advances in the treatment of hair loss in recent years and the future is very encouraging. As our knowledge of androgenetic alopecia pathophysiology increases, novel targeted treatments will potentially be developed.

Abstract
A sensitive gas chromatographic-mass spectrometric method is described for reliably measuring endogenous uracil in 100 microl of human plasma. Validation of this assay over a wide concentration range, 0.025 microM to 250 microM (0.0028 microg/ml to 28 microg/ml), allowed for the determination of plasma uracil in patients treated with agents such as eniluracil, an inhibitor of the pyrimidine catabolic enzyme, dihydropyrimidine dehydrogenase. Calibration standards were prepared in human plasma using the stable isotope, [15N2]uracil, to avoid interference from endogenous uracil and 10 microM 5-chlorouracil was added as the internal standard.

Abstract
We examined the applicability of attribution theory to mothers' perceptions and reactions to their child's problem behavior. Participants were 149 Latina mothers of children with developmental disabilities who were interviewed regarding specific incidents in which their child exhibited a behavior problem. The findings indicate that most mothers viewed their child as not being responsible for the behavior problem. Furthermore, as predicted by attribution theory, mothers who ascribed relatively high responsibility to the child were significantly more likely to report negative emotions (anger and frustration) and aggressive/harsh behavioral reactions than mothers who ascribed low responsibility. Also. mothers were more likely to ascribe high responsibility to the child when the problem was characterized as a behavioral excess than as a behavioral deficit. The results provide support for the applicability of an attributional framework and may have important implications for helping parents in addressing the problem behaviors of their children with developmental disabilities.

Abstract
BACKGROUND Although cyclosporine (CsA) has been a mainstay in liver transplantation immunosuppression the original formulation [Sandimmune (SIM)] has variable absorption, particularly in children. Neoral is a new formulation of CsA that may have improved biovailability that would be advantageous in children. This study was undertaken to assess the pharmacokinetics (PK) and effects on outcome of Neoral versus Sandimmune (SIM) in primary pediatric liver transplant recipients. METHODS Thirty-two patients were randomized to receive Neoral (17 patients) or SIM (15 patients) in the early posttransplant period (days 1-7) in a double-blind fashion. Intravenous CsA was instituted immediately posttransplant followed by Neoral or SIM as soon as the patient was tolerating oral fluids (days 1-7). PK were compared after the first dose (1-7 days), 3 weeks, and 6 and 12 months posttransplant. In addition, side effects, effect of age and food on absorption, and rejection episodes were assessed by intent to treat analysis. Notable characteristics of this study include the use of a central laboratory for all sample analyses and the assessment of renal function using radioisotopic evaluation of glomerular filtration rates. RESULTS At baseline the two groups were comparable. Neoral resulted in higher peak levels of CsA and total drug exposure with comparable time to peak drug levels at days 1-7 and week 3. This trend was maintained at 6 and 12 months. Time on i.v. CsA was reduced in the Neoral group (8.4 vs. 11.1 days) and the weight adjusted daily dose of SIM required to achieve target trough levels was about 2-fold more than Neoral from day 22 onward. In addition, biopsy proven and treated and steroid-resistant rejection episodes were fewer in the Neoral group (6 vs. 12; P=0.01 and 1 vs. 8: P=0.004, respectively). Side effects were comparable in both treatment groups. CONCLUSIONS Neoral was well tolerated and had greater biovailability than SIM without any increase in the incidence of side effects. In addition fewer episodes of rejection were observed with Neoral versus SIM. We conclude that Neoral is the CsA formulation of choice for use in pediatric liver transplant recipients.

Abstract
Although there are new FDA-approved drug therapies to treat hair loss, there are many unapproved agents with claims of effectively treating hair loss. A variety of new over-the-counter agents are available for consumers to use; however, it is difficult to assess how these agents work, costs of these agents, and efficacy. This article covers the new approved and the large multitude of unapproved treatments that are used to treat hair loss.

Abstract
Although AIDS is spreading rapidly in minority communities, little is known about attitudes, knowledge, and behavior related to AIDS and HIV in the Asian community. The purpose of this study was to examine these variables in a sample of gay Asian males, as well as to investigate the relationship between knowledge, sources of information, culturally influenced attitudes and high-risk behaviors in this population. Results from a sample of 60 young Asian men who self-identified as "having sex with other men" indicated they were generally knowledgeable about methods of transmission and prevention, and appeared linked to a large information network that included informal sources such as peers and formal sources. However, significant percentages held culturally biased views of AIDS, such as believing race of partner or one's own gender role in the sexual encounter determined level of risk; and one third of the sample did not use condoms regularly. Having been tested for HIV was associated with holding less traditional cultural beliefs and a higher sexual activity level. Open communication about safer sexual practices was associated with monogamous as opposed to multiple relationships and with decreased tendency to engage in alcohol-related unprotected sex. Variance in overall risk was predicted by demographic variables such as education, age, and level of sexual activity, rather than by the attitudinal factors measured. Limitations of this exploratory study include a time-limited subject recruitment period and consequent small sample size, a homogeneous sample weighted toward young, well-educated, and middle-class respondents, and the exclusion of non-English speaking individuals. Nevertheless, study findings suggest that educational outreach targeting Asians who have sex with other men needs to address inaccurate cultural beliefs about HIV/AIDS, emphasize consistent condom use, and encourage models of open communication with partners about safer sexual practices.
