A changing landscape: diagnosis and management of COPD

Chronic obstructive pulmonary disease (COPD) is a common and often particularly debilitating disease. Progressively worsening breathlessness can limit normal daily functioning, reduce quality of life (QoL) and increase the risk of premature death. Importantly, early diagnosis, improving symptoms and QoL, along with minimising exacerbations and hospital admissions, are primary goals of patient care. In recent years, the assessment of COPD has moved away from equating disease severity solely with the degree of obstructive lung impairment to include patient symptoms, exacerbation history and comorbidities, as well as smoking status. There are now more therapies that reduce symptoms and prevent exacerbations, thereby improving QoL. This review explores the diagnosis and management of COPD and positive clinical approaches to managing patients.

Chiari-like malformation and syringomyelia in American Brussels Griffon dogs

Background

Although Chiari‐like malformation (CM) and syringomyelia (SM) have been described in many small breed dogs, the prevalence and clinical manifestations of this complex have not been documented in a large cohort of American Brussels Griffon (ABG) dogs.

Objectives

To characterize the clinical and magnetic resonance imaging (MRI) features of CM and SM in the ABG breed.

Animals

Eighty‐four American Kennel Club registered ABG dogs were recruited.

Methods

Prospective study. Complete histories and neurologic examinations were obtained before MRI. Images were blindly reviewed and calculations were made by using OsiriX. All analyses were performed by Student's t‐test, Spearman's correlation, ANOVA, and chi‐square test where appropriate.

Results

Chiari‐like malformation and SM were present in 65% and 52% of dogs, respectively. Twenty‐eight percent of dogs had neurologic deficits and 20% had neck pain. Mean central canal (CC) transverse height was 2.5 mm with a mean length of 3.6 cervical vertebrae. Neurologic deficits were significantly associated with a larger syrinx (P = .04, P = .08) and syrinx size increased with age (P = .027). SM was associated with a smaller craniocervical junction (CCJ) height (P = .04) and larger ventricles (P = .0001; P < .001).

Conclusions and Clinical Importance

Syringomyelia and CM are prevalent in American Brussels Griffon dogs. Syrinx size is associated with neurologic deficits, CM, larger ventricles, a smaller craniocervical junction height, neurologic deficits, and cerebellar herniation. Fifty‐two percent of dogs with a SM were clinically normal.

Diagnosis and management of patients with bronchiectasis

Diagnosis of bronchiectasis should be considered in individuals presenting with respiratory symptoms similar to asthma and chronic obstructive pulmonary disease that have not responded to usual treatment. This article provides an overview of the prevalence, diagnosis and management of bronchiectasis to inform nursing care and improve patient outcomes.

Novel study design to assess the utility of the copd assessment test in a primary care setting

The quality of a consultation provided by a physician can have a profound impact on the quality of care and patient engagement in treatment decisions. When the COPD Assessment Test (CAT) was developed, one of its aims was to aid the communication between physician and patient about the impact of COPD. We developed a novel study design to assess this in a primary care consultation. Primary care physicians across five countries in Europe conducted videoed consultations with six standardised COPD patients (played by trained actors) which had patient-specific issues that the physician needed to identify through questioning. Half the physicians saw the patients with the completed CAT, and half without. Independent assessors scored the physicians on their ability to identify and address the patient-specific issues, review standard COPD aspects, their understanding of the case and their overall performance. This novel study design presented many challenges which needed to be addressed to achieve an acceptable level of robustness to assess the utility of the CAT. This paper discusses these challenges and the measures adopted to eliminate or minimise their impact on the study results.

Utility of COPD Assessment Test (CAT) in primary care consultations: a randomised controlled trial

BACKGROUND

One of the aims of the COPD Assessment Test (CAT) is to aid communication between the physician and patient about the burden of chronic obstructive pulmonary disease (COPD) on the patient's life.

AIMS

To investigate the impact of the CAT on the quality of primary care consultations in COPD patients.

METHODS

Primary care physicians across Europe conducted six consultations with standardised COPD patients (played by trained actors). Physicians were randomised to see the patient with the completed CAT (CAT+ arm) or without (no CAT arm) during the consultation. These were videoed and independent assessors scored the physicians on their ability to identify and address patient-specific issues such as depression (sub-score A); review standard COPD issues such as breathlessness (sub-score B); their understanding of the case (understanding score); and their overall performance. The primary endpoint was the global score (sub-scores A+B; scale range 0-40).

RESULTS

A total of 165 physicians enrolled in the study and carried out six consultations each; 882 consultations were deemed suitable for analysis. No difference was seen between the arms in the global score (no CAT arm 20.3; CAT+ arm 20.7; 95% CI -1.0 to 1.8; p=0.606) or on sub-score A (p=0.255). A statistically significant difference, though of limited clinical relevance, was observed in mean sub-score B (no CAT arm 8.8; CAT+ arm 9.6; 95% CI 0.0 to 1.6; p=0.045). There was no difference in understanding score (p=0.824) or overall performance (p=0.655).

CONCLUSIONS

The CAT is a disease-specific instrument that aids physician assessment of COPD. It does not appear to improve detection of non-COPD symptoms and co-morbidities.

Prevalence and some clinical characteristics of equine cheek teeth diastemata in 471 horses examined in a UK first-opinion equine practice (2008 to 2009)

Cheek teeth (CT) diastemata are now recognised as a clinically significant equine disorder, but their prevalence in the general equine population is unknown. There is also limited information on the signalment of affected horses; the more commonly affected Triadan sites; and the shape and clinical characteristics of CT diastemata. During the 12-month study period (2008 to 2009), standardised records were obtained during routine dental examinations performed by five veterinarians in a first-opinion equine practice. Cheek teeth diastemata were identified in 49.9 per cent of all horses (n=471) of mean age 11 years (range one to 30 years), with 83.5 per cent of all diastemata affecting mandibular CT and 16.5 per cent affecting maxillary CT. The mean number of diastemata per case was 1.7 (range one to 20) and the mandibular 07 to 08 position was most commonly affected. Valve diastemata were more common (72.1 per cent prevalence) than open diastemata (27.9 per cent). Food trapping was present in 91.4 per cent of diastemata, with gingivitis and periodontal pockets adjacent to 34.2 per cent and 43.7 per cent, respectively. Halitosis was present in 45.5 per cent of affected horses. There was an age-related increase in both the prevalence of diastemata, and in the numbers of diastemata per affected horse, and horses over 15 years old had a significantly increased proportion of open diastemata.
