Stop using the flotation technique and start weighing salbutamol pressurised metered-dose inhalers without dose counters.

Salbutamol pressurised metered-dose inhalers (pMDIs) are not equipped with dose counters outside the USA. The aim of this study was to describe a simple reproducible method for determining the number of doses remaining in a pMDI based on scale weight. With a laboratory scale, the mean weight of the canisters was 28.61 ± 0.10 g after priming and 14.84 ± 0.23 g after 200 puffs. Similar results were obtained with two common digital scales. We recommend weighing salbutamol canisters on a common digital scale, and replacing an old pMDI with a new one when the weight falls to ≤15 g

Two-year survival after multiple bilateral lung metastasectomies for cranial meningioma

The lung represents a common site of metastases from extrathoracic malignancies, and several studies have strengthened the evidence that complete resection of pulmonary metastases is a useful therapeutic treatment for prolonged survival in selected patients. However, fewer data are available in the literature regarding the role of lung metastasectomy in rare malignancy. We present a case of extensive bilateral lung metastases due to recurrent cranial meningioma, which was successfully treated by aggressive, staged metastasectomies

Inhalation technique practical skills and knowledge among physicians and nurses in two pediatric emergency settings.

Introduction : Correct technique with a pressurized metered-dose inhaler (pMDI) equipped with a valved holding chamber (VHC) or spacer provides an important advantage for adequate control of asthma and virus-induced wheezing in young children. The aim of this study was to assess the ability and knowledge of physicians and nurses to use a pMDI with a masked VHC in two pediatric emergency units. Methods : Study design: two-center observational study. Inhaler use technique was assessed in 50 physicians and 50 nurses using a child mannequin and a validated videotaped nine-step scoring method. The participants' knowledge was evaluated by a questionnaire. Results : The inhalation technique was perfectly mastered by 49% of the study participants and almost perfectly mastered by another 34% (mean score 8.3 ± 0.7; range 5-9). Nurses were more likely than doctors to demonstrate the technique perfectly (66% vs. 32%, p < .05). The two most common errors were forgetting to shake the pMDI between two consecutive puffs (38% of the participants) and putting the patient in an incorrect position (11%). About half of the participants reported that they checked each patient's inhalation technique at every opportunity and knew how to clean the VHC. A large majority did not employ a reliable method to determine the amount of medication remaining in pMDIs without a counter. Conclusion : Healthcare professionals' practical skills and knowledge on inhalation therapy were not completely mastered and could be improved with a mandatory training program
