Exploring Patterns of COPD Exacerbations and Comorbid Flare-Ups.

Background: Comorbidities are known to complicate disease management in patients with Chronic Obstructive Pulmonary Disease (COPD). This is partly due to lack of insight into the interplay of acute exacerbations of COPD (AECOPD) and comorbid flare-ups. This study aimed to explore patterns of AECOPDs and comorbid flare-ups. Methods: Data of increased symptoms were extracted from a 12-month daily symptom follow-up database including patients with COPD and comorbidities (chronic heart failure (CHF), anxiety, depression) and transformed to visualizations of AECOPDs and comorbid flare-up patterns over time. Patterns were subsequently categorized using an inductive approach, based on both predominance (ie, which occurs most often) of AECOPDs or comorbid flare-ups, and their simultaneous (ie, simultaneous start in ≥ 50%) occurrence. Results: We included 48 COPD patients (68 ± 9 years; comorbid CHF: 52%, anxiety: 40%, depression: 38%). In 25 patients with AECOPDs and CHF flare-ups, the following patterns were identified: AECOPDs predominant (n = 14), CHF flare-ups predominant (n = 5), AECOPDs nor CHF flare-ups predominant (n = 6). Of the 24 patients with AECOPDs and anxiety and/or depression flare-ups, anxiety and depression flare-ups occurred simultaneously in 15 patients. In 9 of these 24 patients, anxiety or depression flare-ups were observed independently from each other. In 31 of the included 48 patients, AECOPDs and comorbid flare-ups occurred mostly simultaneously. Conclusion: Patients with COPD and common comorbidities show a variety of patterns of AECOPDs and comorbid flare-ups. Some patients, however, show repetitive patterns that could potentially be used to improve personalized disease management, if recognized.

Rheological Behavior and Printability Study of Tri-Calcium Phosphate Ceramic Inks for Direct Ink Writing Method.

In the biomedical industry, tricalcium phosphate is a bioceramic substance that is frequently employed in the fabrication of scaffolds and bone structures. Fabrication of porous ceramic structures using conventional manufacturing techniques is very challenging because of the brittle nature of the ceramics, which has led to a newly adapted direct ink writing additive manufacturing method. This work investigates the rheology and extrudability of TCP inks to produce near-net-shape structures. Viscosity and extrudability tests found that stable TCP: Pluronic ink of 50 vol.% was more reliable compared to other tested inks prepared from a functional polymer group polyvinyl alcohol. A line study was carried out to identify the printing parameters suitable for printing structures from the selected ink with lesser dimensional error. Printing speed 5 mm/s and extrusion pressure 3 bar was found suitable to print a scaffold through a nozzle of 0.6 mm, keeping the stand-off distance equal to the nozzle diameter. The printed scaffold was further investigated for its physical and morphological structure of the green body. A suitable drying behavior was studied to remove the green body without cracking and wrapping before the sintering of the scaffold.

Overshooting tipping point thresholds in a changing climate.

Palaeorecords suggest that the climate system has tipping points, where small changes in forcing cause substantial and irreversible alteration to Earth system components called tipping elements. As atmospheric greenhouse gas concentrations continue to rise as a result of fossil fuel burning, human activity could also trigger tipping, and the impacts would be difficult to adapt to. Previous studies report low global warming thresholds above pre-industrial conditions for key tipping elements such as ice-sheet melt. If so, high contemporary rates of warming imply that exceeding these thresholds is almost inevitable, which is widely assumed to mean that we are now committed to suffering these tipping events. Here we show that this assumption may be flawed, especially for slow-onset tipping elements (such as the collapse of the Atlantic Meridional Overturning Circulation) in our rapidly changing climate. Recently developed theory indicates that a threshold may be temporarily exceeded without prompting a change of system state, if the overshoot time is short compared to the effective timescale of the tipping element. To demonstrate this, we consider transparently simple models of tipping elements with prescribed thresholds, driven by global warming trajectories that peak before returning to stabilize at a global warming level of 1.5 degrees Celsius above the pre-industrial level. These results highlight the importance of accounting for timescales when assessing risks associated with overshooting tipping point thresholds.

Abrupt changes in Great Britain vegetation carbon projected under climate change.

Past abrupt 'regime shifts' have been observed in a range of ecosystems due to various forcing factors. Large-scale abrupt shifts are projected for some terrestrial ecosystems under climate change, particularly in tropical and high-latitude regions. However, there is very little high-resolution modelling of smaller-scale future projected abrupt shifts in ecosystems, and relatively less focus on the potential for abrupt shifts in temperate terrestrial ecosystems. Here, we show that numerous climate-driven abrupt shifts in vegetation carbon are projected in a high-resolution model of Great Britain's land surface driven by two different climate change scenarios. In each scenario, the effects of climate and CO2 combined are isolated from the effects of climate change alone. We use a new algorithm to detect and classify abrupt shifts in model time series, assessing the sign and strength of the non-linear responses. The abrupt ecosystem changes projected are non-linear responses to climate change, not simply driven by abrupt shifts in climate. Depending on the scenario, 374-1,144 grid cells of 1.5 km × 1.5 km each, comprising 0.5%-1.5% of Great Britain's land area show abrupt shifts in vegetation carbon. We find that abrupt ecosystem shifts associated with increases (rather than decreases) in vegetation carbon, show the greatest potential for early warning signals (rising autocorrelation and variance beforehand). In one scenario, 89% of abrupt increases in vegetation carbon show increasing autocorrelation and variance beforehand. Across the scenarios, 81% of abrupt increases in vegetation carbon have increasing autocorrelation and 74% increasing variance beforehand, whereas for decreases in vegetation carbon these figures are 56% and 47% respectively. Our results should not be taken as specific spatial or temporal predictions of abrupt ecosystem change. However, they serve to illustrate that numerous abrupt shifts in temperate terrestrial ecosystems could occur in a changing climate, with some early warning signals detectable beforehand.

Exacerbation action plans for patients with COPD and comorbidities: a randomised controlled trial.

This international randomised controlled trial evaluated whether COPD patients with comorbidities, trained in using patient-tailored multidisease exacerbation action plans, had fewer COPD exacerbation days than usual care (UC).COPD patients (Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification II-IV) with ≥1 comorbidity (ischaemic heart disease, heart failure, diabetes, anxiety, depression) were randomised to a patient-tailored self-management intervention (n=102) or UC (n=99). Daily symptom diaries were completed for 12 months. The primary outcome "COPD exacerbation days per patient per year" was assessed using intention-to-treat analyses.No significant difference was observed in the number of COPD exacerbation days per patient per year (self-management: median 9.6 (interquartile range (IQR) 0.7-31.1); UC: median 15.6 (IQR 3.0-40.3); incidence rate ratio (IRR) 0.87 (95% CI 0.54; 1.39); p=0.546). There was a significantly shorter duration per COPD exacerbation for self-management (self-management: median 8.1 (IQR 4.8-10.1) days; UC: median 9.5 (IQR 7.0-15.1) days; p=0.021), with no between-group differences in the total number of respiratory hospitalisations (IRR 0.76 (95% CI 0.42; 1.35); p=0.348), but a lower probability of ≥1 for respiratory-related hospitalisation compared to UC (relative risk 0.55 (95% CI 0.35; 0.87); p=0.008). No between-group differences were observed in all-cause hospitalisations (IRR 1.07 (95% CI 0.66; 1.72)) or mortality (self-management: n=4 (3.9%); UC: n=7 (7.1%); relative risk 0.55 (95% CI 0.17; 1.84)).Patient-tailored exacerbation action plans for COPD patients with comorbidities did not significantly reduce exacerbation days, but reduced the duration per COPD exacerbation and the risk of having at least one respiratory-related hospitalisation during follow-up, without excess all-cause mortality.

Analysing Tuberculosis Cases Among Healthcare Workers to Inform Infection Control Policy and Practices.

OBJECTIVE To determine the number and proportion of healthcare worker (HCW) tuberculosis (TB) cases infected while working in healthcare institutions in the Netherlands and to learn from circumstances that led to these infections. DESIGN Cohort analysis. METHODS We included all HCW TB patients reported to the Netherlands TB Register from 2000 to 2015. Using data from this register, including DNA fingerprints of the bacteria profile and additional information from public health clinics, HCW TB cases were classified into 4 categories: (1) infected during work in the Netherlands, (2) infected in the community, (3) infected outside the Netherlands, or (4) outside these 3 categories. An in-depth analysis of category 1 cases was performed to identify factors contributing to patient-to-HCW transmission. RESULTS In total, 131 HCW TB cases were identified: 32 cases (24%) in category 1; 13 cases (10%) in category 2; 42 cases (32%) in category 3; and 44 cases (34%) in category 4. The annual number of HCW TB cases (P<.05), the proportion among reported cases (P<.01), and the number of category 1 HCW TB cases (P=.12) all declined over the study period. Delayed diagnosis in a TB patient was the predominant underlying factor of nosocomial transmission in 47% of category 1 HCW TB patients, most of whom were subsequently identified in a contact investigation. Performing high-risk procedures was the main contributing factor in the other 53% of cases. CONCLUSION In low-incidence countries, every HCW TB case should warrant timely and thorough investigation to help further define and fine-tune the HCW screening policy and to monitor its proper implementation.

Quantitative STIR of muscle for monitoring nerve regeneration.

PURPOSE: To assess whether short tau inversion recovery (STIR) MRI sequences can provide a tool for monitoring peripheral nerve regeneration, by comparing signal intensity changes in reinnervated muscle over time, and to determine potential clinical time points for monitoring. MATERIALS AND METHODS: For this prospective study, 29 patients with complete traumatic transection of the ulnar or median nerves in the forearm were followed up to 45 months postsurgery. Standardized 1.5 Tesla STIR-MRI scans of hand muscles were obtained at fixed time intervals. Muscle signal intensities were measured semi-quantitatively and correlated to functional outcome. RESULTS: For the patients with good function recovery, mean signal intensity ratios of 1.179 ± 0.039, 1.304 ± 0.180, 1.154 ± 0.121, 1.105 ± 0.046 and 1.038 ± 0.047 were found at 1-, 3-, 6-, 9-, and 12-month follow-up, respectively. In the group with poor function recovery, ratios of 1.240 ± 0.069, 1.374 ± 0.144, 1.407 ± 0.127, 1.386 ± 0.128 and 1.316 ± 0.116 were found. Comparing the groups showed significant differences from 6 months onward (P < 0.001), with normalizing signal intensities in the group with good function recovery and sustained elevated signal intensity in the group with poor function recovery. CONCLUSION: MRI of muscle can be used as a tool for monitoring motor nerve regeneration, by comparing STIR muscle signal intensities over time. A decrease in signal intensity ratio of 50% (as compared to the initial increase) seems to predict good function recovery. Long-term follow-up shows that STIR MRI can be used for at least 15 months after nerve transection to differentiate between denervated and (re)innervated muscles. J. Magn. Reson.

Development of a self-treatment approach for patients with COPD and comorbidities: an ongoing learning process.

BACKGROUND: Patient-initiated action plans are an important component of COPD self-management (SM) interventions. When integrated into SM interventions, these action plans have proven to be effective in reducing exacerbation severity, hospitalisations, and costs and in improving health status in patients with COPD without severe comorbidities. Because of overlap in symptoms, a self-treatment (ST) approach that focuses solely on traditional symptoms of COPD is inadequate for patients with COPD and comorbidities. The COPE-III SM intervention combines (I) patient-initiated action plans that are tailored to the individual's co-morbid disease(s), and (II) ongoing nurse support. In this paper we provide information regarding the integration of information from two previous COPD SM studies (COPE I and II) in the development of the current COPE-III ST approach. MATERIALS AND METHODS: COPE-III ST materials include daily symptom diaries and action plans that take patient's common comorbidities [chronic heart failure (CHF), anxiety, depression, ischaemic heart disease (IHD), and diabetes] into account. The comorbid diary and action plans components were developed in collaboration with multiple disease-experts. RESULTS: Previous SM studies have highlighted some essential topics that need to be considered when developing a SM or ST approach: 'when to initiate ST', 'how to optimize materials and safety', and 'how to achieve behavioural change'. In the COPE-III study, ST is initiated after a significant change in symptoms. This is consistent with the COPE-II approach and was implemented because disease symptoms are often present even when patients are stable. We have tried to ensure patient safety by providing an easily accessible case-manager to patients throughout their involvement in the study. Furthermore, a psychologist has ensured the use of behavioural change techniques throughout the intervention. CONCLUSIONS: We should continue to learn from our experiences with SM interventions to further optimize future SM and ST interventions. The use of materials that are suitable for different levels of patient literacy and the training of health care providers are other points of improvement.

Self management for patients with chronic obstructive pulmonary disease.

BACKGROUND: Self management interventions help patients with chronic obstructive pulmonary disease (COPD) acquire and practise the skills they need to carry out disease-specific medical regimens, guide changes in health behaviour and provide emotional support to enable patients to control their disease. Since the first update of this review in 2007, several studies have been published. The results of the second update are reported here. OBJECTIVES: 1. To evaluate whether self management interventions in COPD lead to improved health outcomes.2. To evaluate whether self management interventions in COPD lead to reduced healthcare utilisation. SEARCH METHODS: We searched the Cochrane Airways Group Specialised Register of trials (current to August 2011). SELECTION CRITERIA: Controlled trials (randomised and non-randomised) published after 1994, assessing the efficacy of self management interventions for individuals with COPD, were included. Interventions with fewer than two contact moments between study participants and healthcare providers were excluded. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data. Investigators were contacted to ask for additional information. When appropriate, study results were pooled using a random-effects model. The primary outcomes of the review were health-related quality of life (HRQoL) and number of hospital admissions. MAIN RESULTS: Twenty-nine studies were included. Twenty-three studies on 3189 participants compared self management versus usual care; six studies on 499 participants compared different components of self management on a head-to-head basis. Although we included non-randomised controlled clinical trials as well as RCTs in this review, we restricted the primary analysis to RCTs only and reported these trials in the abstract.In the 23 studies with a usual care control group, follow-up time ranged from two to 24 months. The content of the interventions was diverse. A statistically relevant effect of self management on HRQoL was found (St George's Respiratory Questionnaire (SGRQ) total score, mean difference (MD) -3.51, 95% confidence interval (CI) -5.37 to -1.65, 10 studies, 1413 participants, moderate-quality evidence). Self management also led to a lower probability of respiratory-related hospitalisation (odds ratio (OR) 0.57, 95% CI 0.43 to 0.75, nine studies, 1749 participants, moderate-quality evidence). Over one year of follow-up, eight (95% CI 5 to 14) participants with a high baseline risk of respiratory-related hospital admission needed to be treated to prevent one participant with at least one hospital admission, and 20 (95% CI 15 to 35) participants with a low baseline risk of hospitalisation needed to be treated to prevent one participant with at least one respiratory-related hospital admission.No statistically significant effect of self management on all-cause hospitalisation (OR 0.77, 95% CI 0.45 to 1.30, 6 studies, 1365 participants, low-quality evidence) or mortality (OR 0.79, 95% CI 0.58 to 1.07, 8 studies, 2134 participants, very low-quality evidence) was detected. Also, dyspnoea measured by the (modified) Medical Research Council Scale ((m)MRC) was reduced in individuals who participated in self management (MD -0.83, 95% CI -1.36 to -0.30, 3 studies, 119 participants, low-quality evidence). The difference in exercise capacity as measured by the six-minute walking test was not statistically significant (MD 33.69 m, 95% CI -9.12 to 76.50, 6 studies, 570 participants, very low-quality evidence). Subgroup analyses depending on the use of an exercise programme as part of the intervention revealed no statistically significant differences between studies with and without exercise programmes in our primary outcomes of HRQoL and respiratory-related hospital admissions.We were unable to pool head-to-head trials because of heterogeneity among interventions and controls; thus results are presented narratively within the review. AUTHORS' CONCLUSIONS: Self management interventions in patients with COPD are associated with improved health-related quality of life as measured by the SGRQ, a reduction in respiratory-related hospital admissions, and improvement in dyspnoea as measured by the (m)MRC. No statistically significant differences were found in other outcome parameters. However, heterogeneity among interventions, study populations, follow-up time and outcome measures makes it difficult to formulate clear recommendations regarding the most effective form and content of self management in COPD.

Stable-State Midrange-Proadrenomedullin Level Is a Strong Predictor of Mortality in Patients With COPD.

BACKGROUND: Midrange-proadrenomedullin (MR-proADM) has been shown to be elevated in patients hospitalized for an acute exacerbation of COPD (AECOPD) and in patients with community-acquired pneumonia. When measured during AECOPDs, MR-proADM has also been shown to be a predictor of mortality. We hypothesized that MR-proADM levels measured in a stable state could also predict mortality. METHODS: We included 181 patients in whom we had paired plasma samples for MR-proADM determinations during a stable state and at hospitalization for an AECOPD when they also produced sputum. Time to death or censoring was compared between patients with MR-proADM above or below the median of 0.71 nmol/L. The predictive value of MR-proADM for survival was determined by calculating the C statistic. RESULTS: Patients with COPD and MR-proADM levels > 0.71 nmol/L in the stable state had a threefold-higher risk of dying than did patients with MR-proADM levels < 0.71 nmol/L (hazard ratio, 2.98 [95% CI, 1.51-5.90]; C statistic, 0.76). The corrected OR for 1-year mortality was 8.90 (95% CI, 1.94-44.6) in patients with high MR-proADM levels measured in the stable state, compared with patients with low levels measured in the stable state. CONCLUSIONS: MR-proADM measured in the stable state appeared to be a strong predictor of mortality in patients with COPD. MR-proADM is far easier to measure than other predictors of mortality in COPD, such as BMI, airflow obstruction, dyspnea, and exercise capacity score.

A dedicated dermatology clinic for renal transplant recipients: first 5 years of a New Zealand experience.

AIM: Cancer following organ transplantation is a growing public health concern. We describe the first 5 years' experience of a dedicated dermatology clinic for renal transplant recipients, the first of its type in New Zealand. METHODS: Data from patients seen in the clinic were collected on a nephrology/dermatology database. RESULTS: 86 of 99 transplant recipients had a baseline dermatology assessment. Seventy-one skin cancers (45 squamous, 25 basal cell carcinomas, 1 melanoma) were found in 17 patients. Eighteen of these were an incidental finding at the baseline post-transplant examination of 7 patients: they had not been noted either by the patient or by their nephrologist. A further 44 cancers were found in 13 patients at follow-up examinations in the dedicated clinic. Squamous and basal cell carcinomas received definitive treatment after 26 and 38 days (median) respectively. A brief analysis showed this to be a cost-effective way of diagnosing and treating skin cancer in this cohort of patients. CONCLUSION: The clinic is enabling prompt diagnosis and cost-effective treatment of skin cancers developing in renal transplant recipients and is also identifying significant numbers of pre-existing skin cancers in these patients.

A case of pityriasis rubra pilaris associated with membranous nephropathy.

Pityriasis rubra pilaris (PRP) is a rare idiopathic dermatosis which may be associated with autoimmune diseases, HIV infection, and internal malignancies. Its association with renal diseases is, however, much less recognized. We report a case of PRP with associated membranous nephropathy (MN), which resolved spontaneously with resolution of the dermatosis. This is only the second reported association between PRP and MN of which we are aware. Further reports of such an association will strengthen the evidence for the two conditions being linked and may thereby shed light on the pathogenesis of both PRP and MN.

Telemonitoring of Daily Activity and Symptom Behavior in Patients with COPD.

Objectives. This study investigated the activity behavior of patients with COPD in detail compared to asymptomatic controls, and the relationship between subjective and objective activities (awareness), and readiness to change activity behavior. Methods. Thirty-nine patients with COPD (66.0 years; FEV(1)% predicted: 44.9%) and 21 healthy controls (57.0 years) participated. Objective daily activity was assessed by accelerometry and expressed as amount of activity in counts per minute (cpm). Patients' baseline subjective activity and stage of change were assessed prior to measurements. Results. Mean daily activity in COPD patients was significantly lower compared to the healthy controls (864 ± 277 cpm versus 1162 ± 282 cpm, P < 0.001). COPD patients showed a temporary decrease in objective activities in the early afternoon. Objective and subjective activities were significantly moderately related and most patients (55.3%) were in the maintenance phase of the stages of change. Conclusions. COPD patients show a distinctive activity decrease in the early afternoon. COPD patients are moderately aware of their daily activity but regard themselves as physically active. Therefore, future telemedicine interventions might consider creating awareness of an active lifestyle and provide feedback that aims to increase and balance activity levels.

Excellent adherence and no contamination by physiotherapists involved in a randomized controlled trial on reactivation of COPD patients: a qualitative process evaluation study.

OBJECTIVE: To assess the adherence of physiotherapists to the study protocol and the occurrence of contamination bias during the course of a randomized controlled trial with a recruitment period of 2 years and a 1-year follow-up (COPE-II study). STUDY DESIGN AND SETTING: In the COPE-II study, intervention patients received a standardized physiotherapeutic reactivation intervention (COPE-active) and control patients received usual care. The latter could include regular physiotherapy treatment. Information about the adherence of physiotherapists with the study protocol was collected by performing a single interview with both intervention and control patients. Patients were only interviewed when they were currently receiving physiotherapy. Interviews were performed during two separate time periods, 10 months apart. Nine characteristics of the COPE-active intervention were scored. Scores were converted into percentages (0%, no aspects of COPE-active; 100%, full implementation of COPE-active). RESULTS: Fifty-one patients were interviewed (first period: intervention n = 14 and control n = 10; second period: intervention n = 18 and control n = 9). Adherence with the COPE-active protocol was high (median scores: period 1, 96.8%; period 2, 92.1%), and large contrasts in scores between the intervention and control group were found (period 1: 96.8% versus 22.7%; period 2: 92.1% versus 25.0%). The scores of patients treated by seven physiotherapists who trained patients of both study groups were similar to the scores of patients treated by physiotherapists who only trained patients of one study group. CONCLUSION: The adherence of physiotherapists with the COPE-active protocol was high, remained unchanged over time, and no obvious contamination bias occurred.

Sequential MR imaging of denervated and reinnervated skeletal muscle as correlated to functional outcome.

PURPOSE: To prospectively assess the short inversion time inversion-recovery (STIR) magnetic resonance (MR) signal intensity changes of denervated and reinnervated skeletal muscle over time in clinical patients. MATERIALS AND METHODS: This study was approved by the institutional review board, and informed consent was obtained from all patients. Twenty-three patients with complete traumatic transection of the median or ulnar nerve in the forearm were prospectively followed for 12 months after surgical nerve repair. STIR MR images of selected intrinsic hand muscles were obtained 1, 3, 6, 9, and 12 months after nerve repair, and signal intensities of denervated and reinnervated muscles were measured semiquantitatively. After 12 months, hand function was assessed. Signal intensity ratios were correlated to functional outcome with analysis of variance. RESULTS: Of the 23 patients, 10 had good function recovery, while 13 had poor recovery. For the group with good function recovery, mean signal intensity ratios of 1.267 ± 0.060 (standard deviation), 1.357 ± 0.116, 1.297 ± 0.111, 1.205 ± 0.096, and 1.086 ± 0.104 were found at 1-, 3-, 6-, 9-, and 12-month follow-up, respectively. In the group with poor recovery, mean signal intensity ratios of 1.299 ± 0.056, 1.377 ± 0.094, 1.419 ± 0.117, 1.398 ± 0.111, and 1.342 ± 0.095 were found at 1-, 3-, 6-, 9-, and 12-month follow-up, respectively. Comparison of the group with poor function recovery and the group with good function recovery showed significant differences at 6-, 9-, and 12-month follow-up (P = .035, P = .001, and P < .001, respectively), with normalizing signal intensities in the group with good function recovery and sustained high signal intensity in the group with poor function recovery. CONCLUSION: STIR MR imaging can be used to differentiate between denervated and reinnervated muscles for at least 12 months after nerve transection.

[Sternoclavicular joint tuberculosis]. / Een zwelling bij de clavicula.

A 24-year old woman presented with an abscess localized at the median side of the right clavicle. There were no clinical signs of tuberculosis and radiological evaluation was normal. PCR-assay on tuberculosis following aspiration of the pus collection was positive for Mycobacterium tuberculosis. She responded well on regular anti-tuberculosis treatment.

Toxic alveolitis after inhalation of a water repellent.

Inhalation of fluorocarbon polymers can cause pulmonary toxicity. Although multiple cases of lung injury have been reported, cellular characterization of the associated alveolitis occurring acutely after inhalation is limited. We report the case of a previously healthy woman who presented at our Emergency Department with an acute pneumonitis following inhalation of a fluorocarbon polymer-based rain-proofing spray. Bronchoalveolar lavage (BAL) performed shortly after the presentation showed an elevated total cell count, with a high proportion of neutrophils (58%) and eosinophils (9%). In addition, a lipid stain (Oil-Red-O-stain) showed a high level of lipid laden macrophages, a marker that could reflect a direct toxic effect of the spray on alveolar cells. The patient made a full recovery after four days of in-hospital observation with supportive care.
