A two-year-old male entire border collie dog was evaluated for a short history of mixed bowel diarrhoea, coughing, vomiting and stranguria. Physical examination revealed dyspnoea with increased ventral lung sounds and a flaccidly distended bladder. Neurological examination revealed poor pupillary light reflexes, an absent gag reflex and a poor anal tone. Thoracic radiography was consistent with megaoesophagus and aspiration pneumonia. Clinicopathological testing revealed an elevated muscular nicotinic acetylcholine receptor antibody titre. The dog was euthanased because of clinical deterioration. Cerebrospinal fluid (CSF) collected immediately post-mortem revealed macrophagic pleocytosis. Post-mortem histopathological examination was consistent with dysautonomia. This is the first report of coexisting autoimmune myasthenia gravis and dysautonomia in a non-human species. The concomitant diseases may suggest a common immunopathological aetiology.

Foreign body aspiration can be a life-threatening emergency requiring immediate intervention. However, unlike in children, clinical presentation of foreign bodies in adults often varies with regard to symptoms and signs and occurs without asphyxia. We here describe the case of a 65-year-old man on maintenance hemodialysis who developed dyspnea and left chest aspiration pneumonia after swallowing one tablet of the phosphate binder sevelamer. This case illustrates that elderly patients with swallowing complaints should be taken serious when they complain about their subsequent frustration of ingestion of their pills.

Withholding and withdrawing artificial nutrition and hydration from terminally ill patients poses many ethical challenges. The literature provides little information about the Islamic beliefs, attitudes, and laws related to these challenges. Artificial nutrition and hydration may be futile and reduce quality of life. They can also harm the terminally ill patient because of complications such as aspiration pneumonia, dyspnea, nausea, diarrhea, and hypervolemia. From the perspective of Islam, rules governing the care of terminally ill patients are derived from the principle that injury and harm should be prevented or avoided. The hastening of death by the withdrawal of food and drink is forbidden, but Islamic law permits the withdrawal of futile, death-delaying treatment, including life support. Nutritional support is considered basic care and not medical treatment, and there is an obligation to provide nutrition and hydration for the dying person unless it shortens life, causes more harm than benefit, or is contrary to an advance directive that is consistent with Islamic law. The decision about withholding or withdrawing artificial nutrition and hydration from the terminally ill Muslim patient is made with informed consent, considering the clinical context of minimizing harm to the patient, with input from the patient, family members, health care providers, and religious scholars.

In Parkinson's disease (PD) typical "palliative care" type symptoms, such as pain, nausea, weight loss and breathlessness can occur throughout the condition, but become more prevalent in later disease stages. Pain may be specifically related to PD, e.g. dystonic pain with wearing off, but is more commonly due to other conditions. The cause can usually be elicited by a careful history and examination, and this guides intervention, both non-pharmaceutical, and pharmaceutical. For example, dystonic pain will respond best to appropriate changes to dopaminergic medication. In later disease stages people have increasing problems with swallowing, and also cognitive impairment. Impaired swallowing may lead to aspiration pneumonia, which is a common cause of hospital admission, and also death. Decisions about interventions towards the end of life, such as insertion of percutaneous endoscopic gastrostomy (PEG) tube for nutrition, can be very challenging, particularly if, as in most cases, the person with PD has not previously expressed their views upon this while they still maintained capacity to make decisions. Advance care planning (ACP) in PD should be encouraged in relation to interventions such as PEG tubes. It may also cover issues such as preferred place of death. Over recent years lower proportions of people have been dying at home, and this is especially true for PD, but home may well be where they would have preferred to die. However, there is little evidence to guide health professionals about how, when, and by whom, ACP should be approached.

A 7-year-old spayed female German Wirehaired Pointer was presented with difficulty breathing after being found seizing in a water-filled drainage ditch while out hunting. Aspirates from a tracheal wash contained numerous degenerate neutrophils, fewer macrophages, some of which contained basophilic debris, low numbers of extracellular diatoms, and a single intracellular short bacterial rod. As the dog continued to clinically decline and could not be weaned from oxygen support, the owners chose euthanasia. The major necropsy finding was a severe granulomatous bronchopneumonia that was likely due to aspiration of foreign material based on the microscopic presence of plant-like material, bi-refringent crystalline material, non-cellular debris, and occasional fungal structures. Diatoms are a class of algae that live primarily in water. Diatom analysis has been used, with some controversy, in human forensics to assist in documenting drowning as the cause of death. In this case, given the clinical history, the presence of diatoms and inflammation in the tracheal wash were interpreted as a likely result of the aspiration of surface water. To our knowledge, this is the first reported case of diatoms observed in a cytologic specimen in a nonhuman mammal with aspiration pneumonia.

Damage to lungs may occur from systemic as well as inhalational exposure to various illegal drugs of abuse. Aspiration pneumonia probably represents the most common pulmonary complication in relation to consciousness impairment. Some pulmonary consequences may be specifically related to one given drug. Prolonged smoking of marijuana may result in respiratory symptoms suggestive of obstructive lung disease. Non-cardiogenic pulmonary edema has been attributed to heroin, despite debated mechanisms including attempted inspiration against a closed glottis, hypoxic damage to alveolar integrity, neurogenic vasoactive response to stress, and opiate-induced anaphylactoid reaction. Naloxone-related precipitated withdrawal resulting in massive sympathetic response with heart stunning has been mistakenly implicated. In crack users, acute respiratory syndromes called "crack-lung" with fever, hemoptysis, dyspnea, and pulmonary infiltration on chest X-rays have been reported up-to 48h after free-base cocaine inhalation, with features of pulmonary edema, interstitial pneumonia, diffuse alveolar hemorrhage, and eosinophil infiltration. The high-temperature of volatilized cocaine and the presence of impurities, as well as cocaine-induced local vasoconstriction have been suggested to explain alveolar damage. Some other drug-related pulmonary insults result from the route of drug self-administration. In intravenous drug users, granulomatous pneumonia with multinodular patterns on thoracic imaging is due to drug contaminants like talcum. Septic embolism from right-sided endocarditis represents an alternative diagnosis in case of sepsis from pulmonary origin. Following inhalation, pneumothorax, and pneumomediastinum have been attributed to increased intrathoracic pressure in relation to vigorous coughing or repeated Valsalva maneuvers, in an attempt to absorb the maximal possible drug amount. In conclusion, pulmonary consequences of illicit drugs are various, resulting in both acute life-threatening conditions and long-term functional respiratory sequelae. A better understanding of their spectrum and the implicated mechanisms of injury should help to improve patient management.

We report a surgical case of tension pyopneumothorax in a patient who was receiving chemotherapy for esophageal cancer. A 68-year-old man who had undergone total gastrectomy with splenectomy for gastric cancer and was receiving chemotherapy for esophageal cancer was presented to our hospital with dyspnea. Left tension pyopneumothorax was diagnosed, and he received left lower lobectomy after pleural drainage. His postoperative course was uneventful, and he is alive without any cancer recurrences 5 years after the lobectomy. Once tension pyopneumothorax has developed from lung abscess, emergent lobectomy may be a useful option to prevent lethal aspiration pneumonia.

Three dogs presented for evaluation of acute onset tachypnoea and dyspnoea following episodes of vomiting and/or regurgitation. Thoracic radiographs were suggestive of a gastro-oesophageal intussusception in all three dogs; one dog also showed evidence of aspiration pneumonia. All three dogs underwent surgical correction with a bilateral incisional gastropexy. All dogs recovered from anaesthesia uneventfully and were discharged from the hospital 3 days after presentation. Persistent megaoesophagus was evident in all three dogs, and they are being chronically managed with a strict feeding regime and pro-motility agents.

Diaphragmatic paresis is a rare but recognized complication of atrial fibrillation ablation.A 59-year-old woman experiencing dyspnea in supine position and for minimal effort was admitted in a cardiac rehabilitation center. One month before, she was referred to a cardiac center to ablation of paroxysmal atrial fibrillation. After the procedure, the patient developed respiratory failure attributed to aspiration pneumonia and requiring mechanical ventilation.At admission in the rehabilitation center, M-mode ultrasonography reported an absence of movement of the right hemidiaphragm during quiet breathing and a paradoxical movement during voluntary sniffing.Chest ultrasonography can be useful to detect diaphragmatic dysfunction in patients suffering from dyspnea, at admission in a cardiac rehabilitation center. Its use should be envisaged more frequently.

An 80-year-old woman initially presented with an episode of pleuritic chest pain 10 days after implantation of a dual chamber permanent pacemaker. She returned to hospital a day later with vomiting and fever. She was found to have new atrial fibrillation in addition to right-sided weakness and dysarthria. An infarct in the left anterior inferior cerebellar artery territory was later confirmed on CT. She continued to have recurrent febrile episodes associated with vomiting and dyspnoea. Extensive investigations for infection were negative, and her symptoms were initially attributed to aspiration pneumonia. The patient gradually deteriorated despite antibiotics and became progressively short of breath, with development of large pleural and pericardial effusions. A diagnosis of postcardiac injury syndrome was made after exclusion of other differentials. The patient recovered well after pleurocentesis, pericardiocentesis and a pericardial window, with resolution of symptoms without further medical therapy.
