Radiation Therapy Skin Marking with Lancets Versus Electric Marking Pen (COMFORTATTOO)-6 Months Results on Cosmesis, Fading, and Patients' Satisfaction From a Randomized, Double-Blind Trial.

Purpose: Most of radiation oncology centers rely on set-up skin markings for patient setup during treatment delivery. Permanent dark-ink tattooing is the most popular marking method. COMFORTATTOO is a unicentric, randomized trial testing 2 permanent methods: lancets against an electric marking pen (Comfort Marker 2.0, CM). One substudy was undertaken to test if using the CM translates into a cosmesis, fading, or satisfaction benefit compared with the lancets. Methods and Materials: Patients aged 18 years or older referred to our department to receive RT were recruited. They were randomly assigned, in a 1:1 ratio, to receive set-up markings using lancets or CM. This substudy aimed to recruit all the living participants included in the main study. The primary endpoints were tattoos cosmesis, tattoos fading, and patients' satisfaction 6 months after finishing the RT. Cosmetic and fading assessments were scored on a 5-point ascending scale and patients' satisfaction on a 10-point ascending scale. The trial is registered at ClinicalTrials.gov (number NCT05371795). Results: Between April and September 2022, 92 patients were enrolled (45 assigned to lancets and 47 to CM) and assessed for the outcomes. Patients receiving CM had significantly better cosmetic markings, with a median score of 4.4 (vs 3.7 for lancets, P<.001). On the fading assessment, the CM was associated with lower scores compared with the lancets (median score of 1.3 and 3.3, respectively; P<.001). No differences in patients' satisfaction were observed with either method (median score of 10 for both arms, P=.952). Conclusions: Our substudy results demonstrated that, 6 months after the end of RT, the CM produces better cosmetic markings with less fading compared with the lancets. These differences didn't translate into patients' satisfaction superiority toward any method.

Malignant Transformation of Retroauricular Hidradenoma in Hidradenocarcinoma in a Nine-Year-Old Patient: A Case Report.

Hidradenocarcinoma, a rare malignant entity that derives from sweat glands, is especially rare in the pediatric population. The treatment of choice is surgery. Radiation therapy is used only in selected patients. Chemotherapy is not used extensively because its effectiveness has not been demonstrated yet. This case report describes a nine-year-old female patient who presented in 2018 with a vegetative lesion in the right parietal region. After excisional surgery, pathology confirmed that the lesion was a benign hidradenoma. However, the lesion recurred six months later, and subsequent surgery revealed nodular hidradenoma with positive margins. In July 2019, a new heterogenous lesion appeared in the right retroauricular region, which was surgically removed. The pathology report found possible malignant characteristics, and the patient was referred to our hospital where she was diagnosed with poorly differentiated right retroauricular carcinoma with infiltrative and perineural permeation, along with homolateral lymph node metastasis. It was histologically compatible with a hidradenocarcinoma. The patient underwent a wide-margin excision and homolateral total cervical lymphadenectomy, followed by adjuvant radiotherapy. The last follow-up MRI was negative for disease recurrence or metastasis; however, a slow-growing node on the left jugular chain (level II) was noted. The patient is on regular follow-ups to monitor disease status and treatment-related adverse events. This case highlights the challenges of diagnosing and treating hidradenocarcinoma, a rare malignancy that requires aggressive management with a multidisciplinary approach. More robust clinical evidence is needed to define the best treatment approach for these aggressive tumors.

Drug reaction with eosinophilia and systemic symptoms (DRESS) with severe and atypical lung involvement.

Drug reaction with eosinophilia and systemic symptoms is a rare and potentially fatal drug hypersensitivity reaction. Reactions include skin eruption, fever, hematologic abnormalities (eosinophilia or atypical lymphocytosis), enlarged lymph nodes, and/or organic involvement. The liver is the most commonly compromised organ. We present a case of drug reaction with eosinophilia and systemic symptoms associated with Naproxen intake in a young female patient with severe lung involvement. The patient's chest tomography highlights the presence of adenomegalies, pericardial and pleural effusion, peribroncovascular consolidations, and centrilobular nodules. After reviewing the literature few similar cases were found. The main radiological alterations in those cases included interstitial opacities attributed to pneumonitis. Therefore, this case study is considered an unusual case with atypical presentation of drug-induced eosinophilic lung disease.

Flight physiology training experiences and perspectives: survey of 117 pilots.

INTRODUCTION: Human factors and awareness of flight physiology play a crucial role in flight safety. Even so, international legislation is vague relative to training requirements in hypoxia and altitude physiology. METHODS: Based on a previously developed survey, an adapted questionnaire was formulated and released online for Portuguese pilots. Specific questions regarding the need for pilot attention monitoring systems were added to the original survey. There were 117 pilots, 2 of whom were women, who completed the survey. RESULTS: Most of the pilots had a light aviation license and flew in unpressurized cabins at a maximum ceiling of 10,000 ft (3048 m). The majority of the respondents never experienced hypoxic symptoms. In general, most of the individuals agreed with the importance of an introductory hypoxia course without altitude chamber training (ACT) for all pilot populations, and with a pilot monitoring system in order to increase flight safety. DISCUSSION: Generally, most of the pilots felt that hypoxia education and training for unpressurized aircraft is not extensive enough. However, almost all the respondents were willing to use a flight physiology monitoring system in order to improve flight safety.
