Adult-onset Langerhans cell histiocytosis with multisystem involvement: A rare case report.

Langerhans cell histiocytosis (LCH) is a rare disorder, especially among adults, characterized by abnormal accumulation of dendritic histiocytes in various tissues, presenting as either single- or multi-system disease. In adults, spinal involvement is less common than long bone, while central nervous system manifestations, such as pituitary gland enlargement and stalk thickening, affect about a quarter of adult patients and may lead to significant endocrine disorders. Salivary gland involvement is another extremely rare manifestation of LCH.

Clinical utility of F-fluorodopa positron emission tomography in the movement disorder clinic: an Australian experience.

Background: Differentiating idiopathic Parkinson disease (iPD) from other causes of tremor and parkinsonism based on clinical grounds can be challenging, particularly early in the course of disease or in the case of atypical clinical presentations. F-fluorodopa (F-DOPA) is a positron emission tomography (PET) radioligand that can be used to demonstrate the presence and pattern of striatal presynaptic dopaminergic deficit and, thus, assist in the diagnosis of iPD and related disorders.

Aims: To determine the clinical utility of F-DOPA PET in an Australian movement disorder clinic setting.

Danger Biomarkers in Perfusates From Fatty Liver Grafts Subjected to Cold Storage Preservation in Different Preservation Solutions.

Static cold storage remains the traditional standard for liver graft preservation prior to transplantation in both clinical and experimental settings. The use of polyethylene glycol 35 solutions, such as Institut Georges Lopez-2 (IGL2) preservation solution, for protecting against mitochondrial damage during cold static preservation necessitates combination with hypothermic oxygenated perfusion to enhance liver graft performance. This study presents a preliminary comparative evaluation of "danger signals" indicating hepatocellular injury (transaminases, lactate content), mitochondrial damage (glutamate dehydrogenase release), and cytokine release in liver perfusates from suboptimal grafts (fatty livers) subjected to 24-hour cold storage.

[Six-month real-world outcomes of intravitreal clindamycin for ocular toxoplasmosis].

Objective: To evaluate in a real-world setting an intravitreal clindamycin treatment protocol for ocular toxoplasmosis.

Methods: This was a single-center, retrospective review with a 6-month follow-up. Our protocol proposed an IVT of clindamycin as first-line treatment, and management was chosen according to the patient's status (past medical history of ocular toxoplasmosis or not).
