There has been a significant evolution in the definition and management of sepsis over the last three decades. This is driven in part due to the advances made in our understanding of its pathophysiology. There is evidence to show that the manifestations of sepsis can no longer be attributed only to the infectious agent and the immune response it engenders, but also to significant alterations in coagulation, immunosuppression, and organ dysfunction. A revolutionary change in the way we manage sepsis has been the adoption of early goal-directed therapy. This involves the early identification of at-risk patients and prompt treatment with antibiotics, hemodynamic optimization, and appropriate supportive care. This has contributed significantly to the overall improved outcomes with sepsis. Investigation into clinically relevant biomarkers of sepsis are ongoing and have yet to yield effective results. Scoring systems such as the sequential organ failure assessment and Acute Physiology and Chronic Health Evaluation help risk-stratify patients with sepsis. Advances in precision medicine techniques and the development of targeted therapy directed at limiting the excesses of the inflammatory and coagulatory cascades offer potentially viable avenues for future research. This review summarizes the progress made in the diagnosis and management of sepsis over the past two decades and examines promising avenues for future research.
A 69-year-old man without a family history of breast cancer presented to his primary care physician with a 1-year history of clear, unilateral nipple discharge (ND) without an associated palpable breast mass. His laboratory findings were significant for hyperprolactinaemia at 28 ng/mL. Diagnostic work up including mammography, ultrasound and core needle biopsy ultimately revealed a ductal carcinoma in situ and a rare papillary variant of invasive ductal carcinoma. The patient was referred to a multidisciplinary oncology team and underwent a right total mastectomy followed by adjuvant hormonal therapy. The patient made a good postoperative recovery and remains without evidence of recurrence 6 months from surgery. Male breast cancer is rare, but its incidence is increasing. Male breast cancer presenting as ND without a palpable mass is uncommon. Early recognition of breast symptoms in men can lead to earlier diagnoses and improved outcomes.
Background: Miller Fisher syndrome is a variant of acute inflammatory demyelinating polyneuropathy classically characterized by ataxia, ophthalmoplegia, and areflexia. Miller Fisher syndrome can present with uncommon symptoms such as bulbar, facial, and somatic muscle palsies and micturition disturbance. Case presentation:We describe the case of a 76-year-old white man with new-onset ataxia, stridor, areflexia, and upper and lower extremity weakness who required intubation at presentation. An initial work-up including imaging studies and serum tests was inconclusive. Eventually, neurophysiological testing and cerebrospinal fluid analysis suggested a diagnosis of Miller Fisher syndrome. Our patient responded to treatment with intravenous immunoglobulin and supportive therapy.Conclusion: The occurrence of acute or subacute descending paralysis with involvement of bulbar muscles and respiratory failure can often divert clinicians to a diagnosis of neuromuscular junction disorders (such as botulism or myasthenia gravis), vascular causes like stroke, or electrolyte and metabolic abnormalities. Early identification of Miller Fisher syndrome with appropriate testing is essential to prompt treatment and prevention of further, potentially fatal, deterioration.
Hydrothorax is a rare complication of peritoneal dialysis occurring in about 2% of continuous ambulatory peritoneal dialysis (CAPD) patients. These effusions occur soon after the onset of dialysis and are usually right-sided. We describe an unusual case of late-onset, left-sided, and recurrent effusions in the setting of CAPD.A 67-year-old patient with end-stage renal disease on CAPD for the last three years was admitted to our hospital with acute hypoxic respiratory failure secondary to a left-sided effusion. Although previously asymptomatic, he had three admissions for bilateral (left predominant) effusions in the last year, all of which were found to be transudative on analysis. Therapeutic thoracentesis once again revealed a transudative effusion with an elevated pleural fluid-serum glucose gradient. On this occasion, pleuro-peritoneal scintigraphy with technetium-99m was performed, uncovering a communication between the peritoneal cavity and the left pleural cavity. The peritoneal dialysis was substituted with hemodialysis, and the patient showed an eventual resolution of left-sided effusions within 18 months.Hydrothorax in peritoneal dialysis is due to the transudation of fluid across congenital or acquired pleuro-peritoneal communications. Pleural fluid with protein content less than 3 g/dl, high glucose, and low lactate dehydrogenase (LDH) relative to blood, and the presence of both D and L isomers of lactic acid suggest a transdiaphragmatic leak. Early diagnosis via peritoneal scintigraphy and appropriate management can prevent significant morbidity and mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
