Bordetella bronchiseptica is a gram-negative coccobacillus that colonizes the respiratory system of mammals such as dogs, cats, rabbits and others and might cause upper respiratory tract infections. Although it can be rarely pathogenic in humans, there are several case reports describing infections in humans. We describe the case of a patient without prolonged immunosuppression or underlying diseases, with bacteremia from Bordetella bronchiseptica, while being treated in a tertiary hospital for COVID-19 infection.

Non-alcoholic fatty liver disease (NAFLD) is a slowly progressive chronic disease, with a high prevalence among obese, dyslipidemic or diabetic people, commonly presented as an asymptomatic mild elevation of serum aminotransferases. We report a patient who experienced an acute form of non-alcoholic steatohepatitis, as the first manifestation of NAFLD, due to exacerbation of pre-existing metabolic disorders by an extremely unhealthy lifestyle. A 50-year old, obese, diabetic man presented with a one-week history of jaundice and malaise. Analysis revealed elevated liver enzymes, bilirubin, lipids, and glucose. Based on patient’s history, physical examination, laboratory results, and imaging findings, acute non-alcoholic steatohepatitis was established as a diagnosis of exclusion. The patient was started on a low-calorie diet free of carbohydrates and fats, in combination with insulin. A dramatic improvement of clinical and laboratory parameters was observed. In the context of extreme metabolic dysregulation, induced by unhealthy diet, NAFLD may present as an acute steatohepatitis.

Introduction. Infective endocarditis in the left heart may be complicated by stroke, due to embolisation from infectious valvular vegetations. Infarction of both occipital lobes, which are supplied by the posterior cerebral arteries, is infrequent, and is the cause of cortical blindness from lesion of the visual cortex. Cortical blindness is characterized by intact pupillary reflexes, a normal fundoscopy, and, rarely, denial of visual loss.Case Presentation. We report the case of a 58-year-old woman, recipient of a mechanical aortic valve, who presented with fever, multiple organ dysfunction, and cortical blindness. Transesophageal echocardiography and blood cultures confirmed the diagnosis of infective endocarditis caused by methicillin-sensitiveStaphylococcus aureus. Computed tomography of the brain without contrast revealed the presence of infarctions in both occipital lobes. It is noteworthy that the visual loss resolved after treatment of endocarditis.Conclusions. A stroke occurring in a patient presenting with fever and a history of valvular heart disease strongly suggests the presence of infective endocarditis. Bilateral thromboembolic infarcts of the occipital lobes cause cortical blindness, that can resolve after treatment of endocarditis.

Introduction Intensive care may prolong the dying process in patients who have been unresponsive to the treatment already provided. Limitation of life-sustaining therapy, by either withholding or withdrawing support, is an ethically acceptable and common worldwide practice. The purpose of the present study was to examine the frequency, types, and rationale of limiting life support in Greek intensive care units (ICUs), the clinical and demographic parameters associated with it, and the participation of relatives in decision making. Methods This was a prospective observational study conducted in eight Greek multidisciplinary ICUs. We studied all consecutive ICU patients who died, excluding those who stayed in the ICU less than 48 hours or were brain dead. Results Three hundred six patients composed the study population, with a mean age of 64 years and a mean APACHE II score on admission of 21. Of study patients, 41% received full support, including unsuccessful cardiopulmonary resuscitation (CPR); 48% died after withholding of CPR; 8%, after withholding of other treatment modalities besides CPR; and 3%, after withdrawal of treatment. Patients in whom therapy was limited had a longer ICU (P < 0.01) and hospital (P = 0.01) length of stay, a lower Glasgow Coma Scale score (GCS) on admission (P < 0.01), a higher APACHE II score 24 hours before death (P < 0.01), and were more likely to be admitted with a neurologic diagnosis (P < 0.01). Patients who received full support were more likely to be admitted with either a cardiovascular (P = 0.02) or trauma diagnosis (P = 0.05) and to be surgical rather than medical (P = 0.05). The main factors that influenced the physician's decision were, when providing full support, reversibility of illness and prognostic uncertainty, whereas, when limiting therapy, unresponsiveness to treatment already offered, prognosis of underlying chronic disease, and prognosis of acute disorder. Relatives' participation in decision making occurred in 20% of cases and was more frequent when a decision to provide full support was made (P < 0.01). Advance directives were rare (1%). Conclusions Limitation of life-sustaining treatment is a common phenomenon in the Greek ICUs studied. However, in a large majority of cases, it is equivalent to the withholding of CPR alone. Withholding of other therapies besides CPR and withdrawal of support are infrequent. Medical paternalism predominates in decision making.

Background Renal cell carcinoma is associated with a wide spectrum of para-neoplastic syndromes, which may be precursors of primary or recurrent disease. Non-metastatic hepatic dysfunction in patients suffering from renal cell carcinoma is known as Stauffer's syndrome. It is associated with the production of cytokines by the tumour, and several biochemical abnormalities, including elevated serum alkaline phosphatase. Case presentation We describe a 36-year-old woman presenting with various non-specific, systemic disease manifestations, and elevated liver enzymes due to cholestasis as the main laboratory abnormality. Imaging studies showed a solid mass in the left kidney, which, after surgical excision, was identified as renal cell carcinoma. No metastasis was found. Conclusion Stauffer syndrome may precede other manifestations of renal cell carcinoma. In case of unexplained abnormal liver function, particularly in presence of systemic symptoms, underlying renal cell carcinoma should be excluded by focused investigations.
