Invasive fungal diseases (IFD) are difficult to treat and pose a significant threat to immunocompromised individuals. Current antifungal agents face limitations, including antifungal resistance and adverse effects. This review aims to give a comprehensive overview of emerging treatment strategies.Novel drugs in development are Ibrexafungerp, an orally available triterpenoid inhibiting glucan synthesis, and Rezafungin representing the echinocandins with extended half-life and improved tissue penetration, both recently licensed for certain indications. Fosmanogepix targets glycosylphosphatidylinositol biosynthesis, while Olorofim, an orotomide, inhibits fungal nucleic acid synthesis, both currently assessed in advanced clinical trials.Immunotherapeutic approaches include immune checkpoint inhibitors to enhance immune response in immunosuppressed individuals and fungal-specific allogeneic CAR-T cell therapy. For prophylactic purpose in high-risk populations to develop IFD, monoclonal antibodies against different virulence factors of Candida spp. have been discovered but are not yet seen in clinical trials. Vaccines against distinct fungal antigens as well as pan fungal vaccines to prevent IFD are under development in preclinical stages, notably for Candida spp., Cryptococcus spp., and Aspergillus spp., however, their clinical value is still discussed.In summary, major advances to treat IFD have been observed, but challenges for their establishment in the clinical routine persist.

Single-sided deafness (SSD) is characterised by deafness in one ear while the other ear has normal hearing. The most common cause in congenital SSD is aplasia of the auditory nerve, and in post-lingual SSD idiopathic hearing loss. Patients with SSD mainly suffer from impaired sound localisation and difficulties in speech perception in noise. There are various therapy options, but binaural hearing is only possible with a cochlear implant (CI).

Introduction: Subglottic stenoses (SGS) are constrictions in the region below the vocal folds, that can pose a life-threatening problem for those affected. The aim of this research project was to identify the patient group for which the treatment of SGS by balloon dilatation can lead to long-term success.

Methods: 14 patients with SGS were examined (before and up to12 months after intervention) using pulmonary function tests, laryngoscopies and two questionnaires (Clinical Chronic Obstructive Pulmonary Disease Questionnaire), (modified Medical Research Council Dyspnoea Scale) regarding the respiratory situation. Additionally, the number of necessary interventions, the degree of stenosis (according to Myer Cotton and measured in millimeters) were documented.

Results: Four patients who required only one intervention with the balloon showed better pre-interventional respiratory function and a higher subjective stress level. Lung function tests and evaluation of the questionnaires showed an improvement in the respiratory situation and state of health of all 14 patients after the initial intervention. The degree of stenosis measured in millimeters shows that patients with a stenosis diameter of less than 4 mm only required one intervention. All patients who received an intervention using a 12-mm-balloon had to be treated several times.

Conclusions: Patients with a high degree of stenosis and a tendency towards greater subjective stress and less objective restriction of the respiratory function appear to have a higher probability of long-term successful treatment with the balloon. Furthermore, the choice of balloon size seems to be an additional decisive factor for the success of an intervention.

Background: Almost all e-cigarettes contain flavorings that make the product more attractive. In the evaluation of e-cigarettes on health, flavors have so far played a subordinate role.

Method: Selective literature search in PubMed, supplemented by legal regulations on the use of flavors in e-cigarettes.

Results: Flavors make it easier to start using e-cigarettes and have a consumption-promoting effect. Deeper inhalation increases nicotine uptake and the absorption of toxic substances from the e-cigarette liquid. For some flavors, pathological effects have been demonstrated in addition to other toxic components of the e-cigarette. To date, no toxicological analyses are available for the vast majority of flavors contained in e-cigarettes.

Conclusions: The proven consumption-promoting effect and the health risks that can be extrapolated from preclinical data are significant for the political discussion of a ban on flavors for e-cigarettes, analogous to the ban on flavors in tobacco products already in force.

Nowadays, it is only relatively rare and in selected situations that colonic interposition is chosen rather than the stomach as a reconstructive organ for replacing the oesophagus. The colon is a reliable organ for tubular replacement of the oesophagus when the stomach is not available for reconstruction. Colon interposition is a complex and complicated operation. It requires a specific indication and thorough preoperative preparation. From a technical point of view, colon interposition places high demands on the selection and surgical dissection of the vascular supply to the reconstructed organ. The reconstruction route and elevation of the interposition graft to the proximal oesophagus and the need to create 3 or 4 gastrointestinal anastomoses also place significantly higher demands than reconstruction using a gastric tube. Overall, despite the significant surgery-related morbidity, good functional results and a good quality of life can usually be achieved. The surgical technique applied in our own practice is described in detail. An overview from literature on the results of colonic interposition is given, particularly with regard to surgical complications and quality of life after colon interposition.

Endoscopy is the gold standard for diagnosis of oesophageal cancer and its precursor lesions. Besides this, endoscopy treatment of these precursor lesions and early oesophageal cancer has been well evaluated and established. This includes dysplastic lesions associated with Barrett's oesophagus and early adenocarcinoma, as well as early squamous cell cancer of the oesophagus. The role of endoscopy for diagnosis and treatment of these lesions is summarised.

Asthma is a heterogeneous inflammatory airway disease that causes relevant morbidity across individuals of all age cohorts. In recent years, advances in the understanding of asthma pathophysiology have led to the development of treatments tailored to specific pheno- and endotypes of the disease. This has significantly changed asthma management, especially for patients with severe disease. These new treatment options offer individuals with asthma access to personalized and disease-modifying therapies. The present paper is a comprehensive overview of recent clinical studies and of German and international guideline updates on asthma management.
