Prevalence and psychopathological characteristics of depression in consecutive otorhinolaryngologic inpatients

Background

High prevalence of depression has been reported in otorhinolaryngologic patients (ORL). However, studies using a semi-structured interview to determine the prevalence of depression in ORL are lacking. Therefore the present study sought to determine the depression prevalence in ORL applying a semi-structured diagnostic interview and to further characterize the pathopsychological and demographic characteristics of depression in these patients.

Methods

One-hundred inpatients of the otorhinolaryngologic department of a German university hospital participated voluntarily (age M = 38.8 years, SD = 13.9; 38.0% female). Depression was assessed using a clinical interview in which the International Diagnostic Checklist for depression (IDCL) was applied. Patients completed the Brief Symptom Inventory (BSI) which constitutes three composite scores and nine symptom scales and the Beck Depression Inventory (BDI). Multivariate analyses of variance, correlations and effect sizes were conducted.

Results

A prevalence of depression of 21.0% was determined, 38.0% of the depressed patients were female. Depressed patients showed higher scores on the BSI-scales "interpersonal sensitivity", "depression", "anxiety", "phobic anxiety" and "psychoticism" with medium effect sizes.

Conclusions

High prevalence of depression was found which is in accordance with results of prior studies. Depressed patients showed higher psychological distress as compared to non-depressed patients. The results call for carrying on in engaging in depression research and routine depression screening in ORL.     

Successful colchicine administration in facial granulomas caused by cosmetic implants: report of a case

Injectable cutaneous microimplants may occasionally cause either persistent local irritation or late skin reactions in the form of foreign body granulomas at the injected areas. Permanent elimination of the latter is not easily achieved. The skin of a female patient developed nodules along the treated sites on her face a few months following the last session of intracutaneous injections. Intralesional steroids offered temporary and incomplete clearance. Colchicine was administered orally for better results.     

Melatonin’s actions are not limited to sleep

Melatonin is widely available as a supplement, usually for sleep disorders. The consumption of melatonin supplements has increased considerably in recent years. An overlooked aspect of melatonin’s administration is the resulting increase in prolactin secretion, via its action on hypothalamic dopaminergic neurons. We believe that since the effect of melatonin on prolactin is tangible, the laboratory finding of hyperprolactinemia could be encountered more often, given the increase in melatonin’s use. This is an issue that merits further study.     

Liver function in transgender persons: Challenges in the COVID-19 era

Transgender persons constitute a non-negligible percentage of the general population. Physical gender-transitioning in trans persons is mainly achieved with hormonal cross-sex therapy and sex reassignment surgeries that aim to align bodily appearance with gender identity. Hormonal treatment acts via suppressing the secretion of the endogenous sex hormones and replacing them with the hormones of the desired sex. The administration of testosterone is the typical masculinizing treatment in trans me...     

BRAF vs RAS oncogenes: are mutations of the same pathway equal? differential signalling and therapeutic implications

As the increased knowledge of tumour heterogeneity and genetic alterations progresses, it exemplifies the need for further personalized medicine in modern cancer management. Here, the similarities but also the differential effects of RAS and BRAF oncogenic signalling are examined and further implications in personalized cancer diagnosis and therapy are discussed. Redundant mechanisms mediated by the two oncogenes as well as differential regulation of signalling pathways and gene expression by RAS as compared to BRAF are addressed. The implications of RAS vs BRAF differential functions, in relevant tumour types including colorectal cancer, melanoma, lung cancer are discussed. Current therapeutic findings and future viewpoints concerning the exploitation of RAS-BRAF-pathway alterations for the development of novel therapeutics and efficient rational combinations, as well as companion tests for relevant markers of response will be evaluated. The concept that drug-resistant cells may also display drug dependency, such that altered dosing may prevent the emergence of lethal drug resistance posed a major therapy hindrance.     

Biochemical parameters of bronchoalveolar lavage fluid in fat embolism

Objective To identify diagnostic markers distinguishing between acute lung injury/acute respiratory distress syndrome (ALI/ARDS) due to fat embolism syndrome (FES) and that due to other causes, and to investigate whether phospholipase A₂ and platelet-activating factor (PAF) play a role in the pathogenesis of ALI due to FES.Design and setting A prospective study in a 14-bed ICU.Patients We studied 13 patients with FES, 11 with ALI/ARDS from other causes (6 without trauma, ALI/ARDS group 1; 7 with trauma, ALI/ARDS group 2) and 5 without cardiopulmonary disease.Measurements and results We compared broncholveolar lavage (BAL) fluid alterations in the respective groups. Total BAL protein in FES group was significantly higher compared to in ALI/ARDS group 1 and controls but ALI/ARDS group 2. Higher total phospholipids were found than in other groups. The alterations in individual phospholipid classes were similar to those in ALI/ARDS patients. However, total cholesterol, lipid esters, and monoglycerides were significantly higher in FES than in other groups. The level of PAF in FES was significantly higher and there was an inverse correlation between PAF and PAF-acetylhydrolase. Phospholipase A₂ activity was significantly higher in both FES and ALI/ARDS groups than in control.Conclusions The levels of neutral lipids and especially cholesterol and cholesterol esters in BAL can be used to distinguish patients with FES from ALI/ARDS due to other predisposing factors. Phospholipase A₂ may be involved in the development, and PAF-acetylhydrolase in the downregulation of inflammation in FES.
