Case Reports[Celebrations with consequences: fever, dyspnea and chest pain].
We report on a 35-year-old male patient who presented to the emergency department a day after celebrations. The night before, the alcoholized patient tried to spit fire with an oily fuel paste. A fever, dyspnea and chest pain were present. ⋯ Aspiration of oily fuel paste led to lipoid pneumonia. Few such cases have been described so far, but the medical history, symptoms and radiological imaging are very characteristic. Antibiotic therapy is not primarily necessary, however, depending on the clinical condition may help to prevent bacterial superinfection. The administration of systemic steroids is controversial in this situation.

Pharmacogenomics (PGx) is a key component of personalized medicine to improve clinical outcome of drug therapy and/or to avoid adverse drug reactions. Major efforts are currently spent internationally to implement PGx diagnostics into clinical practice. Evidence-based recommendations for dose-adjusted treatment which are established by international expert groups covering clinical and pharmacological expertise are publicly available. Clinical relevant examples for PGx diagnostics such as genetic testing for dihydropyrimidin-dehydrogenase and thiopurin-S-methyltransferase, as well as for various cytochrome P450 enzymes are summarized to promote the clinical implementation process of PGx in Germany.

The updated guidelines for the management of dyslipidaemias 2019 sticks to the concept of individual risk-based intervention strategies, but intensifies LDL-C goals. Next to the established SCORE system non-invasive imaging techniques such as coronary CT or ultrasound of carotid or femoral arteries are now recommended for improved risk stratification. Screening for lipoprotein(a) identifies persons at higher cardiovascular risk. ⋯ Cardiovascular risk reduction depends on the absolute lowering of LDL-C, duration of therapy and the individual cardiovascular risk. For patients at very high risk the new LDL-C goal is < 1.4 mmol/l (55 mg/dl) and reduction of ≥ 50 % from baseline. The overall aim is to reduce "cholesterol life years".

Atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of morbidity and mortality. The fact that elevated levels of low-density lipoprotein-cholesterol (LDL-C) play a causal role in the development of ASCVD is now well accepted, given the results of numerous epidemiological and genetic studies, as well as randomized controlled clinical trials. Statins have become a primary therapeutic cornerstone in ASCVD prevention since they have been shown to reduce CV events by reducing levels of LDL-C. ⋯ These aspects include not only a high variability in individual response to therapy, but also possible side effects, potentially reducing adherence to treatment. Most importantly, an elevated risk for cardiovascular (CV) events remains in a large proportion of high-risk patients, especially in those with persistent elevation of LDL-C levels despite a maximum tolerated dose of statin therapy. Also, large clinical trials currently investigate a potential CV benefit of drug therapies targeting elevated levels of triglycerides and lipoprotein (a), respectively.

Review[Metformin Therapy During Surgical Interventions and Iodinated Contrast Agent Use].
Metformin as first-line treatment in type 2 diabetes mellitus (T2 D) shows benefits in terms of reducing cardiovascular events, but the risk of a lactic acidosis as a serious adverse event especially in patients with decreased renal function is still relevant. Since the perioperative management of Metformin or its use in diagnostic procedures with contrast agents is inconsistent in literature and different in practice, the results of various guidelines are reviewed below showing the current state of evidence. Despite many guidelines, the evidence on both issues is low, as they are mainly based on consensus recommendations. ⋯ At present, it is not possible to give reliable recommendations for practice with the aim of minimising the interruption of therapy. For this reason, only a strictly conservative approach with 48-hour breaks before and after both measures can be recommended at present. For the situations mentioned in this overview, the question of the right approach has not yet been conclusively and definitely answered, therefore further studies should be carried out.
