Safety in Dermatologic Procedures: Accidental Injury to Major Blood Vessels and Nerve Structures. / Seguridad en procedimientos dermatológicos: sección de grandes vasos sanguíneos y estructuras nerviosas.

This article in the series «Safety in Dermatologic Procedures¼ deals with the accidental laceration of major blood vessels and nerve structures during surgery. We first look at the anatomic location and course of the blood vessels and nerve structures that are most at risk of injury and then describe the possible outcomes in each case. We finally offer some recommendations on how to avoid damage to structures in danger zones and how to repair them if they are accidentally compromised.

Analysis of Undergraduate Dermatology Syllabi at Spanish Universities: Does the Weight of Theoretical Content Match the Skin Conditions Seen in Primary Care and General Dermatology Practices? / Análisis de las características de la docencia de pregrado de Dermatología en las universidades españolas. ¿Los contenidos teóricos se aproximan a la casuística de los médicos de Atención Primaria y dermatólogos generales?

INTRODUCTION: Undergraduate dermatology courses vary in the nearly 50 Spanish medical faculties that teach the subject. This study aimed to describe the characteristics of these courses and to analyze whether the weight assigned to dermatology topics reflect the caseloads of primary care physicians and general dermatologists in the Spanish national health system. MATERIAL AND METHODS: Cross-sectional study of syllabi used in Spanish medical faculties during the 2021-2022 academic year. We determined the number of teaching hours in public and private university curricula and compared the weight of dermatology topics covered to the dermatology caseloads of primary care physicians and general dermatologists as reported in published studies. RESULTS: Most medical faculties taught dermatology for one semester. The median number of credits offered was 4.5. On average, lectures covered 24 theoretical topics, and seminars and workshops covered 9 topics. We identified a clear disparity between the percentage of time devoted to dermatology topics in course lectures and the skin conditions usually managed in primary care and general dermatology practices. DISCUSSION: The skin diseases most commonly treated by primary care physicians and general dermatologists are underrepresented in the curricula of Spanish medical faculties. The topics that should be given more weight in syllabi, or recovered for inclusion in dermatology courses, should be re-examined. Our findings show that the topics that ideally should be emphasized more are types of dermatitis, infectious skin diseases, acne, psoriasis, rashes, and the differential diagnosis of benign and malignant neoplasms. There should be additional support for the theoretical teaching of these topics.

Safety in Dermatologic Procedures: Basic and Advanced Cardiopulmonary Resuscitation. / Seguridad en procedimientos dermatológicos: Reanimación cardiopulmonar básica e instrumental.

This article in the series on safety in dermatologic procedures covers the delivery of basic cardiopulmonary resuscitation (using no devices), instrumental resuscitation (using an automated external defibrillator), and pharmacological resuscitation (using adrenaline). We provide a brief overview of the updated 2021 European Resuscitation Council guidelines and offer an algorithm and visual aids to support recommended practices.

Artificial Intelligence in Dermatology: A Threat or an Opportunity? / Inteligencia artificial en dermatología: ¿amenaza u oportunidad?

The worldwide explosion of interest in artificial intelligence (AI) has created a before-and-after moment in our lives by generating great improvements in such sectors as the automotive and food production industries. AI has even been called the fourth industrial revolution. Machine learning through AI is helping to improve professional processes and promises to transform the health care sector as we know it in various ways: 1) through applications able to promote health in the general population by providing high-quality information and offering advice for different segments of the population based on prediction models; 2) by developing prediction models based on anonymized clinical data, for preventive purposes in primary care; 3) by analyzing images to provide additional decision-making support for health care providers, for improving specialist care at the secondary level; and 4) through robotics applied to processes that promote health and well-being. However, the medical profession harbors doubts about whether this revolution is a threat or an opportunity owing to a lack of understanding of AI technology and the methods used to validate its applications. This article outlines basic aspects of AI as it is applied in dermatology and reviews the main advances achieved in the last 5 years.

What Proportion of the Spanish Dermatology Caseload Corresponds to Primarily Sexually Transmitted Infections and Other Anogenital Dermatoses? Results From the DIADERM National Random Survey. / ¿Cuánta carga asistencial suponen las infecciones de transmisión predominantemente sexual y otras dermatosis anogenitales en las consultas de Dermatología en España? Resultados del muestreo aleatorio nacional DIADERM.

BACKGROUND AND OBJECTIVE: Predominantly sexually transmitted infections (STIs) and infestations and other anogenital dermatoses are covered in the training of specialists in dermatology and venereology in Spain. This study aimed to analyze the proportion of the dermatology caseload these diseases account for within the public and private dermatological activity of the Spanish health system. MATERIAL AND METHODS: Observational cross-sectional study of time periods describing the diagnoses made in outpatient dermatology clinics, obtained through the anonymous DIADERM survey of a representative random sample of dermatologists. Based on diagnostic codes of the International Classification of Diseases, Tenth Revision, 36 related diagnoses were selected, and classified into 12 groups. RESULTS: Only 3.16% of diagnoses corresponded to STIs and other anogenital dermatoses. The most common diagnostic group was anogenital human papillomavirus infection, followed by molluscum contagiosum, and inflammatory anogenital dermatoses. Lesions with these diagnoses were usually the main reasons for first visits in the National Health Service. In private practice, the diagnoses usually came after referrals from other physicians. CONCLUSIONS: STIs and other anogenital dermatoses account for a very small proportion of the dermatology caseload in Spain, although the inclusion of molluscum contagiosum diagnoses overestimates these conditions. The fact that no STI centers or monographic STI consultations were included in the random sample of dermatology partly explains the under-representation of these areas of the specialty. A determined effort to support and promote monographic STI centres and clinics should be made.

Safety in dermatologic procedures: anaphylaxis, vasovagal reaction, and hyperventilation.

This article, part of a the series on safety in dermatologic procedures, covers the diagnosis, prevention, management, and treatment of 3 situations or conditions. The first condition we address is anaphylaxis, an uncommon but severe and potentially fatal reaction that must be recognized quickly so that urgent management coordinated with an anesthesiologist can commence. The second is fainting due to a vasovagal reaction, which is the most common complication in dermatologic surgery. This event, which occurs in 1 out of every 160 procedures, usually follows a benign course and resolves on its own. However, in patients susceptible to vasovagal reactions, syncope may lead to asystole and cardiac arrest. The third is acute hyperventilation syndrome, which is an anomalous anxiety-related increase in breathing rate beyond metabolic requirements. Brief practical recommendations for managing all 3 events are included.

What Proportion of the Caseload at Dermatology Outpatient Clinics in Spain Do Skin Tumors Account for? Results from the DIADERM National Random Sampling Project. / ¿Cuánta carga asistencial supone la enfermedad tumoral cutánea en la actividad ambulatoria en la Dermatología española? Resultados del muestreo aleatorio nacional DIADERM.

INTRODUCTION AND OBJECTIVE: A significant part of a dermatologist's activity involves the diagnosis and management of tumors. The aim of this study was to analyze the caseload at public and private dermatology outpatient clinics in Spain to determine the proportion of tumor diagnoses. MATERIAL AND METHOD: Observational cross-sectional study of diagnoses made in dermatology outpatient clinics during 2 data-collection periods in the DIADERM study, an anonymous survey of a random, representative sample of dermatologists across Spain. Diagnoses made during the 2 periods were coded according to the CIE-10. There were 165 tumor-related codes, classified into 24 groups. For the purpose of this study, these groups were then reduced to benign melanocytic lesions, malignant melanocytic lesions, benign nonmelanocytic lesions, and malignant nonmelanocytic lesions. RESULTS: Tumors accounted for 46.2% of all diagnoses; 18.5% of the tumors were malignant (a category that included in situ forms of keratinocyte cancers). Four of the 10 most common diagnoses were of malignant tumors: in situ keratinocyte cancers, basal cell carcinoma, melanoma, and squamous cell carcinoma. Significant differences were observed between malignant and benign tumors according to type of practice (public vs. private) and geographic region. CONCLUSION: Skin cancer accounts for a significant part of the dermatologist's caseload in Spain. Differences can be observed depending on the public/private healthcare setting and other factors.

Melanoma Arising in a Melanocytic Nevus. / Melanoma asociado a nevo melanocítico.

The association of melanoma with a preexisting melanocytic nevus varies considerably between series, depending on whether the association is based on histological signs (4%-72%) or a clinically evident lesion (42%-85%). Histological association with a nevus correlates with favorable prognostic factors, whereas a clinical association correlates with unfavorable factors. In this review, we discuss the characteristics of nevus-associated melanoma from different perspectives: Whiteman's divergent pathway hypothesis for the development of cutaneous melanoma; and the factors involved in nevogenicity, including both the genetic and molecular factors involved in the development of the melanoma and its precursor lesions. Finally, a cumulative analysis of the 16 162 cases reported in the literature revealed that 29.8% of melanomas are histologically associated with a melanocytic nevus.

Microwave Treatment for Axillary Hyperhidrosis and Bromhidrosis. / Tratamiento con microondas en la hiperhidrosis y bromhidrosis axilar.

Axillary hyperhidrosis (AH) and bromhidrosis are common causes of consultation in dermatology. Currently, the most widely prescribed treatment for AH is botulinum toxin, a very effective but temporary option; it is totally ineffective in bromhidrosis. Sympathectomy is an increasingly infrequent choice of treatment due to the high incidence of compensatory hyperhidrosis. We describe the treatment of AH and bromhidrosis with a novel microwave device that can fibrose eccrine and apocrine glands, achieving possibly permanent results. The procedure should preferably be performed under tumescent anesthesia. Side effects, principally local inflammation, are transient. Clinical effectiveness and safety, supported by recently published studies, position this technique as a first-choice option both for hyperhidrosis and for bromhidrosis.

Phototherapy in atopic dermatitis: a systematic review of the literature.

BACKGROUND: Phototherapy is a treatment option for atopic dermatitis recommended by several guidelines. OBJECTIVE: To perform a systematic review of the efficacy of different modalities of phototherapy and photochemotherapy in moderate to severe atopic dermatitis. MATERIAL AND METHODS: We considered all randomized clinical trials (RCTs) performed in patients with atopic dermatitis, and accepted all outcome measures. Articles were identified via an online search of the MEDLINE (via Ovid) and Embase databases and the Cochrane Central Register of Controlled Trials. We also searched for clinical trials registered in Current Controlled Trials and in the World Health Organization's International Clinical Trials Registry Platform. RESULTS: Twenty-one RCTs (961 patients) were included in the qualitative analysis. Two of the trials included children and adolescents (32 patients). The efficacy of narrow-band UV-B and UV-A1 phototherapy was similar for the different outcome measures contemplated. Two RCTs assessed the efficacy of psoralen plus UV-A therapy (PUVA). No serious adverse events were described. In general, the publications reviewed were characterized by a high risk of bias and poor reporting of methodology and results. CONCLUSIONS: There is evidence for the use of narrow-band UV-B and UV-A1 phototherapy in moderate to severe atopic dermatitis. Evidence supporting the use of PUVA in atopic dermatitis is scarce and there is little information on the use of phototherapy in childhood. For the purpose of future studies, it would be advisable to use comparable criteria and scales for the evaluation of disease severity and patients, to standardize radiation methods, and to establish a minimum follow-up time.
