Case Reports[Severe lead poisoning caused by ayurvedic medicine].
We report the case of a young patient who presented to our emergency department with reduced general condition, anemia, and crampy abdominal pain. A previous inpatient workup including abdominal imaging and bone marrow aspiration had not yielded a diagnosis. On inquiry, the patient reported oral ingestion of an Ayurvedic remedy over the course of one month. ⋯ Lead has toxic effects on all organ systems of the body and is stored in the bone for decades. Symptoms of poisoning are nonspecific; a thorough history and generous indication for measuring lead levels are helpful for the diagnosis.

The prevalence of Parkinson's disease (PD) will double by 2030. PD is no longer regarded as a single disease entity. Monogenetic forms may appear clinically identical to sporadic PD. ⋯ Patients who need levodopa more than 5 times a day and who have severe, disturbing OFF phases (> 2 hours a day) despite optimal non-levodopa-based treatment can consider these options. PD stage and symptom-focused, guideline-based physiotherapy has a positive effect on the course of the disease, everyday performance and quality of life and reduces the risk of falling. Multidisciplinary networks are proving effective in reducing falls and hospital admissions.

Treatment of myeloproliferative neoplasia (MPN) is based on patients' individual risk-stratification and includes cytoreductive agents for high-risk essential thrombocythemia (ET), polycythemia vera (PV) and Myelofibrosis (MF). Classical cytoreductive drugs largely fail to modify the basic clonal composition of the disease. In contrast, in PV for example treatment with Ropeg-Interferon not only results in higher hematological response rates compared to hydroxyurea but in addition significantly reduces JAK2 allele-burden in high-risk PV patients as well as it depletes concurrent cytogenetic and molecular abnormalities. ⋯ Both, mutated as well as non-clonal inflammatory and other stromal cells produce significant amounts of local cytokines. Also the initiation of the neoplastic process itself seems to depend on inflammatory cytokines. Recent scRNASeq data revealed components of the alarmin complex (S100A8 und S100A9) drive this local sterile inflammation process, which also represents a potential therapeutic target, as the S100A8 and A9 inhibitor Tasquinimod reduced fibrosis in a pre-clinical animal model.

Amelanotic melanoma (AM) is a subtype of melanoma characterized by a diminished or lacking melanin synthesis. AM, especially ulcerated variants of the plantar region (AMP), are often clinically misdiagnosed, leading to a delay in treatment initiation. ⋯ AMP shows a variety of clinical presentations and particularly elderly patients with many accompanying medical conditions are in danger of incorrect clinical diagnoses. Therefore, we recommend to biopsy any amelanotic plantar ulcer or tumor that does not respond to treatment within 6 weeks to rule out AM.
