Assessment of the quality of life of oncological patients with skin toxicity depending on telemedicine technologies

Relevance. Approximately 90–100% of patients have skin toxicity, which manifests itself in the form of acne-like rashes (papulo-pustular rash), paronychia, hair changes, xerosis, itching. Skin manifestations cause psychological, emotional and physical discomfort, which may be the reason for dose reduction or discontinuation of treatment, and may reduce the effectiveness of antitumor therapy. The use of modern telemedicine systems, such as online consultations and remote monitoring, are designed to make life easier for patients and are now increasingly available and in demand among the general population. The aim of the study. Assessment of the quality of life in cancer patients receiving EGFR inhibitors, depending on the use of remote consultations and remote monitoring.Materials and methods. 140 cancer patients were included in the study. All patients were divided into two groups: in group 1 (study group) n=70, the mobile application «My Health» was used for online-consultation with a dermatologist, in group 2 (comparison group) n=70, offline consultations were used. During the consultations, skin toxicity was assessed using CTCAE scales version 5.0. To analyze the level of quality of life, a questionnaire of the dermatological quality of life index (DLQI) was used, which patients of each group filled out on the day of the start of the study, then after 4 weeks.Results. In patients of the first group, there was a positive dynamic in the state of the skin process compared with the initial indicators. There was a statistically significant improvement in the quality of life, a decrease in the average score for all indicators. In patients of the second group, the positive dynamics of the skin process was not so obvious, as evidenced by the results of the questionnaire. There was a statistically significant strong direct correlation between the value of the results of DLQI and the severity of the disease (rs=0.721 p <0.001).Conclusion. Skin toxicity is a complex interdisciplinary problem that requires an integrated approach between oncologists and dermatologists. Remote monitoring is an accessible form of communication between a doctor and a patient, which contributes to the timely control of skin toxicity in cancer patients receiving EGFR inhibitors.

Mexican Mint (Coleus amboinicus) Emulgel: Natural Solution for Antidandruff Hair Care

Today, the world is developing more and more in all sectors at a faster pace. But with all these developments, people are more prone to falling ill due to factors such as pollution, unhealthy lifestyles, busy work schedules, etc. Nowadays, even children suffer from the issue of dandruff and scalp infections which in later teenage years leads to unhealthy scalp and hair fall problems. Dandruff is a common scalp condition that affects individuals of all ages. It not only causes discomfort but also undermines hair health and aesthetics. Although scalp disorders are not among those that cause severe physical illness or morbidity yet are of great social concern. Scalp and hair conditions have more of a psychological impact on societies. Even minor changes in hair like graying of hair, affects the self-confidence and self-esteem of an individual. There are many types of medications and formulations to treat hair dandruff issues, one of which includes a novel drug delivery system such as “Emulgel” in the form of a mask. The anti-dandruff hair mask offers multiple benefits, including reduction in scalp inflammation and effective management of hair dandruff problems. Furthermore, it rejuvenates the scalp and nourishes hair follicles due to its natural vitamins and nutrient content.

Evaluation of Hair Changes and Damage According to Hair Iron Heating Plate Material

This study investigates the effects of ceramic and polymer heating plates on the surface and structure of hair. To evaluate the degree of hair damage caused by the iron and polymer heating plate materials, hair moisture content and the degree of hair fading were measured using Thermo Gravimetric Analysis (TGA) and a colorimeter, respectively. Additionally, a Scanning Electron Microscope (SEM) was used to analyze the change in the microstructure of the hair. As a result, hair treated using a polymer iron contained significantly higher moisture than hair treated using a ceramic iron. The colorimeter analysis showed that ceramic irons caused fading and damage to hair color, whereas polymer irons did not. Lastly, hair treated with a ceramic flat iron had extensive surface scratches and cuticle melting from the SEM analysis, unlike hair treated with a polymer iron, which preserves superior hair shape and cuticle integrity.

Validation of 11 added items of the outpatient version of the Utrecht Symptom Diary in patients receiving chemotherapy or targeted therapy

IntroductionThe Utrecht Symptom Diary (USD) is a validated Dutch patient-reported outcome measurement (PROM) tool - based on the Edmonton Symptom Assessment System - to assess and monitor symptoms in cancer patients. The USD contains 11 items concerning frequently occurring symptoms in cancer patients (pain, sleeping problems, dry mouth, dysphagia, lack of appetite, abnormal stool, nausea, shortness of breath, fatigue, anxiety and depressed mood) and an item on overall well-being. For the outpatient USD 11 items concerning frequently occurring signs and symptoms in patients receiving chemotherapy and/or targeted therapy were added to the USD: taste alteration, oral pain, weight loss, diarrhoea, hair changes, skin problems, nail problems, eye problems, tingling, concentration problems and problems with sexuality. This current study aimed to evaluate the 11 added items on this treatment specific outpatient USD in cancer patients receiving intravenous chemotherapy and/or targeted therapy.MethodsObservational longitudinal retrospective cohort study including all adult outpatients with cancer receiving intravenous chemotherapy and/or targeted therapy in an academic hospital in the Netherlands who completed at least one outpatient USD as part of routine care (2012–2021). Relevance, comprehensiveness as well as criterion and construct validity were assessed.Results1733 patients who completed ≥ 1 outpatient USD during intravenous chemotherapy and/or targeted therapy were included for analysis. Relevance as well as comprehensiveness of the items on the outpatient USD in this patient population was shown. Criterion validation was demonstrated for all added items of the outpatient USD – except for the item on oral pain. An additional analysis showed that mouth problems were detected with both outpatient USD items oral pain and dry mouth. Construct validity was demonstrated for the items hair changes and skin and nail problems. Construct validity on eye problems was not tested due to the low number of paired outpatient USDs.ConclusionsThe treatment specific outpatient USD is a validated PROM in outpatients with cancer receiving intravenous chemotherapy and/or targeted therapy. Considering its validity in this broad group of patients, we think the treatment-specific outpatient USD is widely applicable. In addition to providing tailored supportive symptom care, the USD-data can be used to increase knowledge about symptom burden in daily practice in this population.

Growth pattern and turnover of carbon and nitrogen measured by stable isotope ratios in the hair of sika deer (Cervus nippon).

Hair is known to preserve diet history and other physiological information during its growth period and is often used in chemical analyses. However, the growth patterns and turnover of hair vary according to the animal species or habitat, so understanding these patterns in the target animal is necessary for interpreting the results of hair analyses. In this study, we aimed to elucidate the growth pattern and dietary information of winter coat hair in captive sika deer (Cervus nippon). Experiments involving hair-staining and shaving were conducted to elucidate the growth pattern of sika deer hair. A diet-switching experiment was conducted to ascertain what dietary information is reflected in the carbon and nitrogen stable isotope values of the deer winter coat. Hair samples collected from each body site (head, shoulder, back, and hip) were analyzed using an elemental analyser interfaced with an isotope-ratio mass spectrometer. The winter coat grows from early September to early November, and then stops after that. During the growth period of the winter coat, the hair of the shoulder and back grew at a constant rate. The carbon and nitrogen stable isotope values of hair reflected the deer's feeding history during hair growth, but there seemed to be a time lag in the hip hair. The results suggest that the guard hair of the shoulder is suitable for hair analysis in sika deer. The obtained information on growth patterns and isotopic change of hair from captive sika deer according to diet be useful for interpreting the results of future analyses using hair samples of wild deer.

A Cost-Effective and Easy-to-Fabricate Conductive Velcro Dry Electrode for Durable and High-Performance Biopotential Acquisition.

Compared with the traditional gel electrode, the dry electrode is being taken more seriously in bioelectrical recording because of its easy preparation, long-lasting ability, and reusability. However, the commonly used dry AgCl electrodes and silver cloth electrodes are generally hard to record through hair due to their flat contact surface. Claw electrodes can contact skin through hair on the head and body, but the internal claw structure is relatively hard and causes discomfort after being worn for a few hours. Here, we report a conductive Velcro electrode (CVE) with an elastic hook hair structure, which can collect biopotential through body hair. The elastic hooks greatly reduce discomfort after long-time wearing and can even be worn all day. The CVE electrode is fabricated by one-step immersion in conductive silver paste based on the cost-effective commercial Velcro, forming a uniform and durable conductive coating on a cluster of hook microstructures. The electrode shows excellent properties, including low impedance (15.88 kΩ @ 10 Hz), high signal-to-noise ratio (16.0 dB), strong water resistance, and mechanical resistance. After washing in laundry detergent, the impedance of CVE is still 16% lower than the commercial AgCl electrodes. To verify the mechanical strength and recovery capability, we conducted cyclic compression experiments. The results show that the displacement change of the electrode hook hair after 50 compression cycles was still less than 1%. This electrode provides a universal acquisition scheme, including effective acquisition of different parts of the body with or without hair. Finally, the gesture recognition from electromyography (EMG) by the CVE electrode was applied with accuracy above 90%. The CVE proposed in this study has great potential and promise in various human-machine interface (HMI) applications that employ surface biopotential signals on the body or head with hair.

The possibilities of correction of premature greying of hair and involutive hair changes

The review highlights the available published data on the etiopathogenesis of early graying, hair involution and restoration methods. Early graying of hair is defined as settlement before the age of 20 in Caucasians, before the age of 25 in Asians and before the age of 30 in Africans. In etiopathogenesis, an imbalance between oxidative stress and the antioxidant system is considered as the leading mechanism, a significant role is played by genetic predisposition, hormonal disorders of the thyroid gland, acute stress; the causes may also be deficiency of vitamin B12, copper, iron. Currently, the active molecule palmitoyl tetrapeptide-20 is used to prevent pigment loss and restore it. The endocannabinoid system in the hair follicle is also considered as a target for stimulation during the restoration of hair growth.

Pili Torti: A Clue to Life-threatening Illness – A Rare Case Report

Menkes kinky hair disease (MKHD) is a rare inherent error of copper metabolism presenting during early infancy with multi-system involvement. It is associated with high morbidity and mortality in early childhood. Characteristic hair changes mirror internal metabolic alterations. Here, we report a case of 13-month-old male child who presented with peculiar changes of skin and hair along with convulsion and high-grade fever. Dermatoscopy and hair mount examination showing pili torti with pigmentary dilution pointed toward the diagnosis of MKHD, which was further enforced with blood investigations showing low copper and ceruloplasmin levels. Cutaneous findings play a crucial role in early diagnosis, thereby reducing morbidity with timely treatment.

Effect of a Hair Loss Management Concurrently Incorporating Aroma Scalp Massage on Hair and Scalp Conditions

This study is a similar experimental study aimed at analyzing the effects of a hair loss management program combined with aroma scalp massage on changes in hair and scalp conditions. The study included 8 participants each in the experimental and control groups, aged 20 to 50, who underwent the hair loss management program once a week for 8 weeks. Data collected were analyzed using the SPSS 26.0 program. The results showed that, firstly, both groups did not show significant differences in hair thickness and density based on the timing of management and between-group differences. Secondly, both groups showed significant increases in moisture and oiliness after 4 and 8 weeks, while stratum corneum amount, pore condition, and scalp surface significantly decreased. A significant decrease in stratum corneum amount was observed in the experimental group after 8 weeks. Thirdly, subjective satisfaction evaluations after management revealed significantly higher satisfaction ratings in the experimental group.

Retrospective clinical study analysis of skin adverse reactions related to epidermal growth factor receptor inhibitors.

Epidermal growth factor receptor inhibitors (EGFRIs) represent a cornerstone in the targeted therapy of malignant tumors. While effective, dermatological adverse events (dAEs) associated with EGFRIs pose a significant challenge, often necessitating treatment discontinuation due to their severity and potential to impede the continuity of cancer therapy. Despite extensive research, the specific mechanisms and predictors of these adverse events remain poorly understood, particularly in diverse populations. This gap in knowledge underscores the need for targeted studies to better predict and manage these events, enhancing patient outcomes and adherence to life-saving therapies. This observational study was conducted at The First Affiliated Hospital of Guangxi Medical University, covering cancer patients treated with EGFRIs from 2020 to 2022. We analyzed clinical data including patient demographics, treatment specifics, and the development and timing of dAEs. The study employed SPSS 26.0 software for data analysis, focusing on the incidence of dAEs and factors influencing their occurrence. We used Kaplan-Meier and Cox regression methods to establish a predictive model for dAEs, tracking their onset and impact on treatment continuity. In our study of 120 patients treated with EGFR inhibitors at The First Affiliated Hospital of Guangxi Medical University, we found a high prevalence of dAEs, with 84.2% of patients experiencing such effects. The most common manifestations were papulopustular rashes, observed as pustules in 52.5% and papules in 57.4% of cases, followed by nail lesions in 62.4% of patients, oral or other mucosal ulcers in 34.7%, and hair changes in 26.7%. The median incubation time (MIT) for dAEs was 5 weeks. We identified drug type, ethnicity, and occupation as statistically significant risk factors (P<0.05 for all) that influenced the MIT, which the Cox regression model further identified as protective factors. Nomograms were developed to assess the risk of dAEs, although it is important to note that these models have only been internally validated, lacking external validation data at this stage. The study highlights the high incidence of EGFRIs-associated dAEs, with specific dermatological manifestations posing significant challenges in cancer therapy. The identification of drug type, ethnicity, and occupation as influential factors on the MIT for dAEs informs clinical decisions. Our prediction model serves as a practical tool for evaluating the risk of developing dAEs over time, aiming to optimize patient management and mitigate treatment interruptions.

A Preliminary Study Examining the Correlation between EGFRI Treatment, Clinic Dermatoscopy Features, and Serum Levels of Anti-Alpha-Galactosyl IgE in Colorectal Cancer Patients

The introduction of molecularly targeted therapies, particularly the epidermal growth factor receptor inhibitors (EGFRIs), has had a positive impact by increasing the life expectancy of patients with advanced colorectal cancer (CRC). The most used anti-EGFRIs monoclonal antagonist, Cetuximab, induces skin responses in most patients, leading to a reduction of dosages or even therapy discontinuation, all with devastating effects. Our study aimed to assess the predictive role and the possible correlations of clinical features, imaging aspects (dermatoscopy), and laboratory tests (anti-alpha-galactosyl IgE levels) for early detection of Cetuximab skin toxicity in patients with metastatic CRC. The association of IgE antibodies against goat alpha-1,3-galactose serum levels with various degrees of skin toxicity encountered during the oncologic treatment resulted in higher concentrations in patients with pruritus and hair changes. Incorporating dermatoscopy into the routine dermatological consultation allowed us to perform a severity assessment, dynamically record, and identify even the erupting lesions previously invisible to classical examination. Hence, we were enabled to generate a broad report and to classify various degrees of skin toxicity severity linked to Cetuximab treatment in 19 patients with metastatic CRC. Detecting the emergent lesions and initiating dermatological treatment in the early stages decreased the severity of skin toxicity. As a result, the duration of the antibiotic treatment was much shorter, and the risk of dose reduction or interruption of the cancer treatment was diminished. In conclusion, we emphasize the need for a regular dermatological examination with dermatoscopy of CRC patients undergoing Cetuximab treatment. Skin toxicity is a significant concern for these patients, and healthcare providers should be vigilant in monitoring and managing this side effect in order to optimize patient care. The correlation between anti-alpha-Gal IgE levels and Cetuximab-induced skin toxicities is an emerging area. More extensive studies need to be published in order to establish this relationship directly.

Age-Invariant Cross-Age Face Verification using Transfer Learning

The integration of face verification technology has become indispensable in numerous safety and security software systems. Despite its promising results, the field of face verification encounters significant challenges due to age-related disparities. Human facial characteristics undergo substantial transformations over time, leading to diverse variations including changes in facial texture, morphology, facial hair, and eyeglass adoption. This study presents a pioneering methodology for cross-age face verification, utilizing advanced deep learning techniques to extract resilient and distinctive facial features that are less susceptible to age-related fluctuations. The feature extraction process combines handcrafted features like Local Binary Pattern/Histogram of Oriented Gradients with deep features from MobileNetV2 and VGG-16 networks. As the texture of the facial skin defines the age related characteristic the well-known texture feature extractors like LBP and HoG is preferred. These features are concatenated to achieve fusion, and subsequent layers fine-tune them. Experimental validation utilizing the Cross-Age Celebrity Dataset demonstrates remarkable efficacy, achieving an accuracy of 98.32%.

Cutaneous manifestations of hypothyroidism: An observational study in a tertiary care center of Eastern India

Background: Changes in skin, hair, and nails may be initial manifestations of an underlying thyroid hormone deficiency. Symptomatic treatment of cutaneous manifestations without treatment of underlying hypothyroidism contributes to long-term morbidity in patients. Aims and Objectives: The aim of the study was to study the cutaneous manifestations and demographic profile of patients with hypothyroidism. Materials and Methods: We conducted a hospital-based cross-sectional study of 200 patients presenting with cutaneous changes in primary hypothyroidism for a period of 18 months. A detailed history, clinical examination, and relevant investigations were performed. Results: Out of 200 patients, cutaneous manifestations were more prevalent in the age group between 30 and 49 years. The ratio of male to female was 1.0:6.4. A family history of hypothyroidism was present in 34.5% of patients. The most common cutaneous features were alteration in skin texture (53.0%), dry skin (48.5%), generalized pruritus (42.5%), urticaria (17%), followed by pigmentation of the skin (34.5%), out of which vitiligo was 9.0%, melasma was 5.5%, and others were 20.0%. Other changes include xerosis (32.5%), eczematous disorder (13%), acquired palmoplantar keratoderma (11.5%), and brittle nails (3.5%). 39.5% had hair changes, out of which diffuse hair loss was 17.5%, coarse hair wa s 12%, alopecia areata was 4.5%, and lateral loss of eyebrows was 4.5%. Changes in the oral cavity and mucous membrane were present in 3.0% of the patients, which included lip vitiligo (1.5%), oral lichen planus (1%), and oral candidiasis (0.5%). Menstrual abnormalities were present in 50.84% of females. The percentage of hypothyroid patients who complained of easy fatigability, facial puffiness, cold intolerance, weight gain, constipation, neck swelling, hoarseness of voice, increased sleeping pattern, and non-pitting edema of feet were 38.5%, 36.5%, 26.0%, 23.5%, 17.0%, 9%, 8%, 7.5%, and 6.5%, respectively. Conclusion: Based on our study, it can be concluded that the presence of certain skin conditions, such as alteration in skin texture, dry skin, generalized pruritus, urticaria, skin pigmentation, and diffuse hair loss, may indicate the possibility of hypothyroidism. These cutaneous manifestations may occur earlier than the diagnosis of hypothyroidism through biochemical testing. Therefore, it is important to consider the possibility of hypothyroidism when examining patients with these skin conditions.

Fractional CO2 laser, platelet rich plasma and combination of both in treatment of female pattern hair loss

Background Female pattern hair loss (FPHL) is one of the most common chronic problems seen by dermatologists worldwide. Hair loss has a significant influence on the quality of life and is associated with low self-esteem and depression. The treatment modalities vary from medical approaches to surgical interventions. However, limited perceived efficacy of a therapeutic regimen may lead to premature stoppage of treatment. Objective To evaluate the efficacy of platelet rich plasma (PRP), fractional CO2 laser and combination of both in treatment of FPHL. Patients and methods This is a split-scalp prospective interventional study in which thirty patients presenting with FPHL received PRP in one area, fractional CO2 in another one, combined fractional CO2 and PRP in a third one and saline intradermal injection in the fourth area in frontal and mid scalp region of scalp. The sessions were scheduled every 2 weeks for 4 sessions, then monthly for 2 months. Patients were evaluated after each session and 3months after the last session. The results were evaluated by trichoscopic and folliscopic examination in the four examined areas. Assessment of treatment response was done according to the count of terminal and vellus hair, the thickness and density of hair shafts and the percentage of change, determined by folliscopic examination. Patients’ satisfaction and side effects were evaluated. Results There was significant difference between the studied groups as regards percentage of change of terminal hair, vellus hair, hair thickness and hair density after treatment. Pairwise comparisons showed that the combined group was statistically better than either PRP, fractional CO2, or saline group as regards all studied parameters (P value was &lt;0.05 for each). Conclusion Combination of fractional CO2 laser and topical PRP application would have a synergistic effect in treatment of FPHL. The technique would be an excellent alternative to injections in order to stimulate hair growth in patients with FPHL.
