Compression therapy after endovenous laser ablation: Patient compliance and impact on clinical outcome.

OBJECTIVES: This study aimed to investigate the impact of post-interventional compression therapy on clinical outcomes after endovenous laser ablation (EVLA) of incompetent saphenous veins. METHODS: This prospective, controlled, multicenter study in Germany involved 493 varicose vein patients followed-up for 6 months. RESULTS: Compression therapy significantly reduced symptoms compared to no compression (VCSS: 1.4 ± 1.6 vs 2.2 ± 2.2; p = .007). Post-interventional therapy duration of up to 14 days was found to be most effective for improving patient-reported disease severity (p < .001) and higher quality of life (p = .001). Patient compliance was high (82%), and non-compliance was linked to worse disease severity (VCSS 1.4 ± 1.5 vs 2.1 ± 2.3, p = .009). CONCLUSION: In conclusion, post-interventional compression therapy is beneficial by reducing symptoms and improving quality of life. High patient compliance with the therapy is observed, and non-compliance is associated with worse disease severity.

Immune checkpoint inhibition and targeted therapy for melanoma: A patient-oriented cross-sectional comparative multicentre study.

BACKGROUND: Choosing the adequate systemic treatment for melanoma is driven by clinical parameters and personal preferences. OBJECTIVE: Evaluation of the impact of disease and treatment on the daily life of patients receiving systemic therapy for melanoma. METHODS: A German-wide, cross-sectional comparative study was conducted at 13 specialized skin cancer centres from 08/2020 to 03/2021. A questionnaire was distributed to assess patients' perception of disease and symptoms, the impact of their current treatment on quality of life (QOL) and activities, adverse events (AEs), therapeutic visits, as well as believe in and satisfaction with their current systemic melanoma treatment. Patient-reported outcomes (PROs) were rated on a continuous numerical rating scale or selected from a given list. RESULTS: Four hundred and fourteen patients with systemic melanoma therapy were included. 359 (87%) received immune checkpoint inhibition (ICI) and 55 (13%) targeted therapy (TT). About 1/3 of patients were adjuvantly treated, the remaining because of unresectable/metastatic melanoma. In subgroup analyses, only in the adjuvant setting, TT patients reported a significant decrease in their treatment associated QOL compared to patients with ICI (p = 0.02). Patients with TT were 1.9 times more likely to report AEs than patients with ICI, a difference being significant just for the adjuvant setting (p = 0.01). ICI treatment intervals differed significantly between adjuvant and unresectable/metastatic setting (p = 0.04), though all patients, regardless of their specific ICI drug, evaluated their treatment frequency as adequate. TT patients with dabrafenib/trametinib (n = 37) or encorafenib/binimetinib (n = 15) did not differ regarding the strain of daily pill intake. Patients older than 63 years rated various PROs better than younger patients. CONCLUSIONS: Patients evaluated their treatment mainly positively. ICI might be preferred over TT regarding QOL and patient-reported AEs in the adjuvant setting. Older melanoma patients appeared to be less impacted by their disease and more satisfied with their treatment.

Cytokine release syndrome-like serum responses after COVID-19 vaccination are frequent and clinically inapparent under cancer immunotherapy.

Patients with cancer frequently receive immune-checkpoint inhibitors (ICIs), which may modulate immune responses to COVID-19 vaccines. Recently, cytokine release syndrome (CRS) was observed in a patient with cancer who received BTN162b2 vaccination under ICI treatment. Here, we analyzed adverse events and serum cytokines in patients with 23 different tumors undergoing (n = 64) or not undergoing (n = 26) COVID-19 vaccination under ICI therapy in a prospectively planned German single-center cohort study (n = 220). We did not observe clinically relevant CRS (≥grade 2) after vaccination (95% CI 0-5.6%; Common Terminology of Adverse Events v.5.0) in this small cohort. Within 4 weeks after vaccination, serious adverse events occurred in eight patients (12.5% 95% CI 5.6-23%): six patients were hospitalized due to events common under cancer therapy including immune related adverse events and two patients died due to conditions present before vaccination. Despite absence of CRS symptoms, a set of pairwise-correlated CRS-associated cytokines, including CXCL8 and interleukin-6 was >1.5-fold upregulated in 40% (95% CI 23.9-57.9%) of patients after vaccination. Hence, elevated cytokine levels are common and not sufficient to establish CRS diagnosis.

[Effectiveness of intralesional steroid injections in granulomatous inflammation after tattooing]. / Therapieansprechen auf intraläsionale Steroidinjektionen bei granulomatöser Entzündungsreaktion nach Tätowierungen.

Tattoos, including permanent makeup, may entail diverse complications like viral or bacterial infections and allergic and inflammatory reactions. In the latter case, besides exogenous pigment, histology shows an either lymphocytic or histiocytic-granulomatous infiltrate, depending on the predominant reaction pattern. We report successful treatment with intralesional triamcinolone acetonide injections in two individuals who developed granulomatous inflammation after tattooing.

A Wide Comparison of Techniques for Repair of PAPVCs: One Institution's 20-Year Experience.

BACKGROUND: Different methods for surgical correction of partial anomalous pulmonary venous connection (PAPVC) exist. We evaluated the outcomes of four techniques regarding morbidity and mortality. METHODS: A total of 116 patients underwent PAPVC repair in our institution over a period of 20 years. Single-patch technique (n = 82 [71%], mean age: 18.59 ± 20.49 years), double-patch technique (n = 13 [11%], mean age: 43.18 ± 25.14 years), Warden's technique (n = 7 [6%], mean age: 10.04 ± 10.47 years), and direct implantation of anomalous pulmonary veins (n = 14 [12%], mean age: 14.42 ± 18.58 years) were examined. RESULTS: Out of the 116 patients, one patient (0.9%) developed pulmonary hypertension after discharge and three patients (2.6%) with normal right cardiac function showed right ventricular failure. In total, a pacemaker was inserted in seven cases (6%). Three patients (2.6%) presented with persistent nonsinus rhythm during follow-up. This complication was most frequently seen in the double-patch group being significantly increased compared with the other groups (p = 0.035). One patient presented with a mild stenosis of the superior vena cava. There were two early, nonsurgery-related deaths and no late mortality. CONCLUSION: Operative therapy of PAPVC has low postoperative morbidity and mortality. Therefore, surgical repair of this cardiac anomaly is a safe and reproducible treatment independent of the applied method. The surgical technique must be selected based on the anatomy and possible accompanying congenital heart defects. Special care should be taken when using the double-patch technique because of significant more frequent nonsinus rhythm events postoperatively.

[Reflectance confocal microscopy in Shiitake dermatitis]. / Konfokale Lasermikroskopie bei Shiitake-Dermatitis.

Shiitake dermatitis usually occurs 1-2 days after consumption of incompletely cooked or raw shiitake mushrooms and is characterized by linear, pruritic, erythematous papulovesicular rashes. It is caused by lentinan, a polysaccharide component of the cell walls of shiitake mushrooms. The histological examination showed an eczema-like morphology with spongiosis and lymphohistiocytic infiltrates. The results of reflectance confocal microscopy (RCM) correlated with the histopathological investigations. Therefore, RCM can be used for non-invasive diagnostic confirmation of Shiitake dermatitis in the future.
