A Retrospective 8-Year Single Institutional Study in Germany Regarding Diagnosis, Treatment, and Outcome of Malignant Parotid Tumors.

This study sought to comprehensively evaluate the diagnosis, therapeutic interventions, and outcomes of individuals afflicted with malignant parotid tumors at a tertiary care otolaryngology department in Heilbronn, Germany, spanning the years 2010-2018. The primary objective was to juxtapose this dataset with findings from analogous single and multicenter investigations. We conducted a meticulous analysis of electronic medical records pertaining to 45 patients subjected to primary parotid cancer treatment.

Resolution of a chronic occipital wound with exposed skull bone with a fish skin graft: a successful treatment approach.

Chronic skin defects in the head, face and neck pose challenges for closure, especially after multiple surgeries or radiation therapy. We report the case of a woman in her 70s with a chronic occipital wound following squamous cell carcinoma resections, resulting in exposed skull bone. Despite various options, we successfully treated the 4 cm x 5 cm wound with a Kerecis fish skin graft (FSG), observing significant improvement within a week.

Clinics and practices in the field of ear, nose and throat medicine (ENT) are experiencing a significant increase in the number of emergency patients, which has multiple reasons. There is broad consent that a reform of emergency structures is necessary.The government commission for modern and needs-based hospital care has made recommendations with statements on the reform of emergency and acute care in the areas of "emergency services and financing" and "integrated emergency centers and integrated control centers".

Quality of Life and Screening on Body Dysmorphic Disorder, Depression, Anxiety in Septorhinoplasty.

Objectives: Septorhinoplasty (SRPL) can improve quality of life (QoL) in functional and aesthetical aspects of the nose. A key factor compromising postoperative satisfaction is symptoms of body dysmorphic disorder (BDD), defined by excessive concerns and distress over slight or imagined physical defects. Although a high prevalence of BDD in SRPL patients is evident, the effect of positive screening on BDD and other psychiatric disorders is understudied.

Successful Medical Management of Bilateral Pneumothorax Due to Nasogastric Tube Misplacement in a Cat.

A 7 yr old female spayed domestic shorthair was evaluated for suspected lily ingestion and acute vomiting. The cat had vomited suspected lily plant material before presentation, and a nasogastric tube (NGT) was placed to continue to administer activated charcoal. The NGT was passed with sedation and limited restraint.

Adenoid hypertrophy-​diagnosis and treatment: the new S2k guideline.

Hyperplasia of the pharyngeal tonsils is to be considered pathologic when nasopharyngeal symptoms of mechanical obstruction and/or chronic inflammation occur. Chronic Eustachian tube dysfunction can result in various middle ear diseases such as conductive hearing loss, cholesteatoma, and recurrent acute otitis media. During examination, attention should be paid to the presence of adenoid facies (long face syndrome), with a permanently open mouth and visible tip of the tongue.

[Recommendations of the German Society of Otorhinolaryngology, Head and Neck Surgery (DGHNO-KHC) for the granting of resident training program authorizations].

The 2018 template for otorhinolaryngology specialist training of the German Medical Association is increasingly implemented by the federal associations. In this regard, the German Society recommended an otorhinolaryngology resident training plan for Otorhinolaryngology, Head and Neck Surgery (DGHNO-KHC) together with the Professional Association of German Otorhinolaryngologists as a suggested guideline for the federal medical associations. In this context, the state medical associations currently work on criteria on the basis of which otorhinolaryngologists and their training institutions can be granted authority for such a certified otorhinolaryngology resident training program.

"Metal-modified base pairs" vs. "metal-mediated pairs of bases": not just a semantic issue!

A "nucleobase pair" is not identical with a "pair of basic ligands", as only in the first case, the existence of inter-base hydrogen bonds is implied. The cross-linking of two nucleobases or two basic ligands by a metal ion of suitable geometry produces either "metal-modified" or "metal-mediated" species, but in the author's opinion, this difference is not always properly made. This commentary is an attempt to provide a clearer distinction between the two scenarios.

[Analysis of ENT emergency patients during the COVID-19 pandemic in Germany].

Background: This retrospective observational study was undertaken to assess the ENT emergency workload during the COVID-19 pandemic caused by the severe acute respiratory coronavirus‑2 (SARS-CoV-2).

Materials And Methods: All 3230 patients who were treated as an emergency from 23.01.

On the Heterogeneous Nature of Cisplatin-1-Methyluracil Complexes: Coexistence of Different Aggregation Modes and Partial Loss of NH Ligands as Likely Explanation.

The conversion of the 1 : 1-complex of Cisplatin with 1-methyluracil (1MeUH), cis-[Pt(NH ) (1MeU-N3)Cl] (1 a) to the aqua species cis-[Pt(NH ) (1MeU-N3)(OH )] (1 b), achieved by reaction of 1 a with AgNO in water, affords a mixture of compounds, the composition of which strongly depends on sample history. The complexity stems from variations in condensation patterns and partial loss of NH ligands. In dilute aqueous solution, 1 a, and dinuclear compounds cis-[(NH ) (1MeU-N3)Pt(μ-OH)Pt(1MeU-N3)(NH ) ] (3) as well as head-tail cis-[Pt (NH ) (μ-1MeU-N3,O4) ] (4) represent the major components.

Can Sex Improve Nasal Function?-An Exploration of the Link Between Sex and Nasal Function.

Objectives: This study was conducted to examine the impact of sexual activity on nasal breathing and compare such effect to that of a nasal decongestant.

Methods: We evaluated nasal breathing at 5 different times: (1) before sexual activity (baseline), (2) immediately after sexual activity, (3) 30 minutes, (4) 1 hour (5), and 3 hours after sexual climax. Same measurements were taken on the second day following application of nasal decongestant spray.

Validating the Xerostomia Inventory in a radiation-induced xerostomia population in German language.

Objectives: Though xerostomia is a frequent oral symptom, there is no validated disease-specific questionnaire in German. The purpose of this study was to translate and validate versions of the Xerostomia Inventory and the Summated Xerostomia Inventory in a German-speaking population.

Participants And Methods: Thirty-nine patients including 18 patients suffering from radiation-induced xerostomia enrolled in this study.

DNA methylation at an enhancer of the three prime repair exonuclease 2 gene (TREX2) is linked to gene expression and survival in laryngeal cancer.

Background: Genetic aberrations in DNA repair genes are linked to cancer, but less is reported about epigenetic regulation of DNA repair and functional consequences. We investigated the intragenic methylation loss at the three prime repair exonuclease 2 (TREX2) locus in laryngeal (n = 256) and colorectal cancer cases (n = 95) and in pan-cancer data from The Cancer Genome Atlas (TCGA).

Results: Significant methylation loss at an intragenic site of TREX2 was a frequent trait in both patient cohorts (p = 0.

Long-Term Quality of Life and Nutritional Status of Patients with Head and Neck Cancer.

Aim: We sought to monitor QOL and nutritional status of patients before, during and after therapy (AT).

Expression of WIF-1 in inflammatory bowel disease.

The WNT/β-catenin cellular network has been extensively studied in numerous diseases including inflammatory bowel disease (IBD). IBD is a condition that increases the risk of developing colorectal cancer. WIF-1 is an inhibitory protein that acts by blocking the interactions of WNT with its receptor complex, thus leading to downregulation of end products of this pathway.

Mixed guanine, adenine base quartets: possible roles of protons and metal ions in their stabilization.

Structural variations of the well-known guanine quartet (G) motif in nucleic acid structures, namely substitution of two guanine bases (G) by two adenine (A) nucleobases in mutual trans positions, are discussed and studied by density functional theory (DFT) methods. This work was initiated by three findings, namely (1) that GA mismatches are compatible with complementary pairing patterns in duplex-DNA structures and can, in principle, be extended to quartet structures, (2) that GA pairs can come in several variations, including with a N1 protonated adeninium moiety (AH), and (3) that cross-linking of the major donor sites of purine nucleobases (N1 and N7) by transition metal ions of linear coordination geometries produces planar purine quartets, as demonstrated by some of us in the past. Here, possible structures of mixed AGAG quartets both in the presence of protons and alkali metal ions are discussed, and in particular, the existence of a putative four-purine, two-metal motif.

The exocyclic amino group of adenine in Pt and Pd complexes: a critical comparison of the X-ray crystallographic structural data and gas phase calculations.

A detailed computational (DFT level of theory) study regarding the nature of the exocyclic amino group, N6H, of the model nucleobase 9-methyladenine (9MeA) and its protonated (9MeAH) and deprotonated forms (9MeA), free and metal-complexed, has been conducted. The metals are Pt and Pd, bonded to nitrogen-containing co-ligands (NH, dien, bpy), with N1, N6, and N7 being the metal-binding sites, individually or in different combinations. The results obtained from gas phase calculations are critically compared with X-ray crystallography data, whenever possible.

Multiple Condensation Reactions Involving Pt(II) /Pd(II) -OH2 , Pt-NH3 , and Cytosine-NH2 Groups: New Twists in Cisplatin-Nucleobase Chemistry.

The coordination chemistry of the antitumor agent cisplatin and related complexes with DNA and its constituents, that is, the nucleobases, appears to be dominated by 1:1 and 1:2 adducts of the types cis-[Pta2 (nucleobase)X] and cis-[Pta2 (nucleobase)2 ] (a=NH3 or amine; a2 =diamine or diimine; X=Cl, OH or OH2 ). Here, we have studied the interactions of the putative 1:1 adducts cis-[Pta2 (1-MeC-N3)(OH2 )](2+) (with a=NH3 , a2 =2,2'-bpy (2,2'-bipyridine), 1-MeC=model nucleobase 1-methylcytosine) with additional cis-[Pt(NH3 )2 (OH2 )2 ](2+) or its kinetically superior analogues [Pd(en)(OH2 )2 ](2+) (en=ethylenediamine) and [Pd(2,2'-bpy)(OH2 )2 ](2+) . Depending upon the conditions applied different compounds of different nuclearity are formed.

The Renaissance of Metal-Pyrimidine Nucleobase Coordination Chemistry.

The significance of metal ions for the function and properties of DNA and RNA, long seen primarily under biological aspects and medicinal uses, has recently gained a renewed momentum. This is a consequence of the advent of novel applications in the fields of materials science, biotechnology, and analytical sensor chemistry that relate to the designed incorporation of transition metal ions into nucleic acid base pairs. Ag(+) and Hg(2+) ions, binding to pyrimidine (pym) nucleobases, represent major players in this development.
