Artificial Intelligence in Radiology - Definition, Potential and Challenges Abstract. Artificial Intelligence (AI) is omnipresent. ⋯ Due to its advanced digitization and its historical technical affinity radiology is especially prone to these developments. But what exactly is AI and what makes AI so potent that established medical disciplines such as radiology worry about their future job perspectives? What are the assets of AI in radiology today - and what are the major challenges? This review article tries to give some answers to these questions.

COVID-19 - More Lung Pocus and Sparing Use of Stethoscope, Chest X-Ray and Lung CT Abstract. For an optimal management of COVID-19 (Coronary Virus Disease) we depend on a fast and reliable diagnosis and severity assessment. The gold standard so far is RT-PCR (reverse transcriptase polmerase chain reaction) from the nasopharyngeal smear. ⋯ Moreover, all three diagnostic examination techniques expose physicians, support staff and subsequent patients to an additional risk of exposure. In view of the contagiousness of SARS-CoV-2 (Severe Acute Respiratory Syndrome Corona Virus), lung point-of-care ultrasound (Lu-PoCUS) is a still underutilized valuable alternative, especially when using pocket devices. In this review the current value and role of stethoscope, pulsoxymetry, chest x ray, lung computer tomography and lung point-of-care ultrasound will be determined based on the available literature.

Although snake bites are rare in Europe, there are a constant number of snake bites in Switzerland. There are two domestic venomous snakes in Switzerland: the aspic viper (Vipera aspis) and the common European adder (Vipera berus). ⋯ Potentially fatal systemic complications are related to disturbances of the hemostatic- and cardiovascular system as well as the central or peripheral nervous system. Beside a symptomatic therapy the administration of antivenom is the only causal therapy to neutralize the venomous toxins.

Wound ballistics examines the specific effect, namely the wound profile, of bullets on the body by firing at synthetic models made of ordnance gelatine, glycerin soap and synthetic bones, validated with real cases from (battlefield) surgery and forensic pathology. Wound profile refers to the penetration depth, the bullet deformation/ fragmentation, the diameter of the permanent and the temporary wound cavity. ⋯ The forensic pathologist can draw conclusions as to the used ammunition based on the wound profile. By measuring of the destructive capability of different ammunition types, wound ballistics lays the foundation for guidelines concerning the maximum effect of military ammunition.

Male breast cancer is a rare disease. Symptoms and signs resemble breast cancer in women: A palpable mass, enlarged lymph nodes or skin changes (ulceration, secretion, peau d'orange) mandate mammography, ultrasound to assess the regional lymph nodes. ⋯ Tamoxifen, not aromatase inhibitors, is the adjuvant therapy of choice for estrogen receptor positive tumors. Therapy of men with metastatic breast cancer follows the same principles as therapy of women.
