Ingrown Toenails: A Survey Among Dermatologists on Current Treatments.

BACKGROUND: To date, there is no formal consensus on how to treat ingrown toenails. Despite the risk of causing irreparable damage to the nail, highly invasive procedures are still common. Less-invasive, matrix-directed techniques with shorter downtime and high cure rates exist, but, perhaps because of a lack of awareness, appear not to have been universally adopted. OBJECTIVE: The authors' study sought to generate data on common practices in the treatment of ingrown toenails. MATERIALS AND METHODS: The authors developed and conducted an online survey to ask dermatologists/dermatosurgeons how they would proceed in 9 different cases of ingrown toenails based on photographs. RESULTS: The authors received 154 replies. Nonsurgical interventions, including advice on nail care/foot baths/ointments/wraps/padding, were always the most frequently chosen option. Removal of the lateral nail plate followed by chemical partial matricectomy (phenolization) was the most or second-most frequently chosen surgical intervention. The answers were highly heterogeneous, and there was no unanimity based on morphology alone. CONCLUSION: Except for a preference for nonsurgical interventions, the authors could not identify any clear treatment standards. The heterogeneity of treatment approaches suggests the need for a guideline.

Telephone follow-up after outpatient nail surgery - a retrospective analysis.

BACKGROUND: One of the areas of care in dermatosurgery is the surgical treatment of diseases of the nail organ. Side effects and complications after nail surgery were investigated by telephone follow-up (TFU), and its suitability for postoperative monitoring and consultation was assessed. PATIENTS AND METHODS: All patients who underwent nail surgery at the Department of Dermatology at the Ludwigshafen City Hospital from October 2019 to December 2021 in outpatient setting were contacted by telephone on the second to third postoperative day and questioned in a standardized manner about postoperative complaints and counselled if necessary. RESULTS: A total of 100 cases were followed up. The most common procedures performed were phenol matricectomy (41%), nail avulsion (16%), and nail matrix biopsies (9%). 50% and 21% of patients reported pain on the day of the procedure and the day after surgery, respectively. After nail avulsion, pain was statistically significantly more frequently reported on the day following the procedure and pain medication was statistically significantly more frequently required (p  =  0.002). Serious adverse events did not occur after nail surgery. 10% of the respondents raised specific questions and needed counseling by TFU. CONCLUSIONS: All nail surgeries were well tolerated in the outpatient setting. Pain was the most common side effect, although only half of all patients reported pain on the day of surgery and only 21% on the day after the procedure. The TFU proved to be an effective and practical as well as easy to establish method for postoperative follow-up and consultation after outpatient nail surgery.

Dermatosurgery - from surgical option to integral part of dermatologic therapy.

Dermatosurgery was long considered an isolated, and not always important, discipline within dermatology. As a therapeutic option, it was considered either the gold standard of first-line therapy, for example in basal cell carcinoma surgery and treatment of early-stage melanoma, or the last option, for instance in the treatment of warts. The fact that a profound change has taken place and that dermatosurgery is now an integral, equal, sometimes leading and always significant component of dermatology will be demonstrated in this review using three examples from geriatric dermatology, the treatment of hidradenitis suppurativa (acne inversa), and melanoma therapy. This review is supplemented by a section on the most important technique in dermatosurgery: microscopic (micrographic) surgery or Mohs Surgery.

Effects of the COVID-19 pandemic on inpatient skin surgery in Germany: results of the DESSI-survey.

BACKGROUND: The aim of the survey was to investigate a possible impairment of inpatient dermatological and dermatosurgical care in Germany due to the COVID-19 pandemic. METHODS: An online survey on the impact of pandemic-related measures on inpatient care was sent to all German dermatology clinics. Only one person per clinic was asked to participate. Data analysis was mainly descriptive. Differences between university hospitals and non-university hospitals were calculated using the Chi-square test. RESULTS: From the 113 dermatological clinics with inpatient care, we received 45 (39.8%) at least partially completed questionnaires. Of these, 25 (55.6%) came from university hospitals, 18 (40.0%) from teaching hospitals of a university, 1 (2.2%) from a non-teaching hospital, and 1 (2.2%) from a participant who did not provide any information on his facility. More than half of survey participants (57.8%) reported that many elective skin surgeries had to be canceled at their clinics at the beginning of the COVID-19 pandemic. However, most of the clinics (75.6%) were able to perform medically necessary surgeries (such as for malignant melanoma). Only 28.9% (13/45) of participants reported that skin surgery in their clinics returned to full strength after the COVID-19 pandemic. There was no statistically significant difference between university hospitals and non-university hospitals regarding the influence of COVID-19-related restrictions. CONCLUSIONS: Despite their heterogeneity, the results of the survey show an overall clear and long-term pandemic-related impairment of inpatient dermatology and skin surgery in Germany.

Perioperative antibiotic prophylaxis in skin surgery - Position paper of the Antibiotic Stewardship working group of the German Society for Dermatologic Surgery (DGDC), Part 1: Procedure- and patient-related risk factors.

The aim of perioperative antibiotic prophylaxis (PAP) is to prevent the occurrence of surgical site infections (SSIs) or other infectious complications (especially bacterial endocarditis or septic arthritis). PAP is effective in surgeries where overall infection rates are high even without considering patient-related risk factors (such as orthopedic surgery or fracture repair). Surgery on airways, gastrointestinal, genital, or urinary tract is also considered to be associated with a risk of infection and may require PAP. Overall, SSIs in skin surgery are relatively rare and vary between 1% and 11% depending on the localization, complexity of the wound closure and patient cohort. Therefore, the general surgical recommendations regarding PAP only partially reflect the needs of dermatologic surgery. In contrast to the USA, where recommendations on the use of PAP in skin surgery already exist, there are currently no guidelines for the use of PAP specifically designed for dermatologic surgery in Germany. In the absence of an evidence-based recommendation, the use of PAP is guided by the experience of the surgeons and leads to a heterogeneous use of antimicrobial substances. In this work, we summarize the current scientific literature on the use of PAP and make a recommendation depending on procedure- and patient-related risk factors.

Perioperative antibiotic prophylaxis in skin surgery - Position paper of the Antibiotic Stewardship working group of the German Society for Dermatologic Surgery (DGDC), Part 2: Special indications and situations.

In addition to prevention of surgical site infections after skin surgery, perioperative antibiotic prophylaxis (PAP) aims to prevent the occurrence of other postoperative infectious complications, especially bacterial endocarditis and hematogenous joint prosthesis infections. This article discusses specific indications for the use of PAP. For example, patients who have undergone any type of heart valve replacement, including transcatheter valve replacement or use of prosthetic material to correct the heart valve, or patients who have experienced bacterial endocarditis, require PAP during skin surgery on mucosal membranes or ulcerated tumors. The use of PAP in special situations such as secondary wound healing, septic dermatosurgery or ulcer surgery is also presented and discussed in detail in this paper based on the current scientific literature. This paper represents the second part of the position paper of the Antibiotic Stewardship Working Group of the German Society for Dermatologic Surgery (DGDC) and summarizes evidence-based recommendations for the administration of PAP during skin surgery for special indications and situations. This is particularly important because, as detailed in Part 1 of this position paper, PAP can and usually should be avoided in skin surgery.

S3 guideline "actinic keratosis and cutaneous squamous cell carcinoma" - update 2023, part 2: epidemiology and etiology, diagnostics, surgical and systemic treatment of cutaneous squamous cell carcinoma (cSCC), surveillance and prevention.

Actinic keratosis (AK) are common lesions in light-skinned individuals that can potentially progress to cutaneous squamous cell carcinoma (cSCC). Both conditions may be associated with significant morbidity and constitute a major disease burden, especially among the elderly. To establish an evidence-based framework for clinical decision making, the guideline "actinic keratosis and cutaneous squamous cell carcinoma" was updated and expanded by the topics cutaneous squamous cell carcinoma in situ (Bowen's disease) and actinic cheilitis. The guideline is aimed at dermatologists, general practitioners, ear nose and throat specialists, surgeons, oncologists, radiologists and radiation oncologists in hospitals and office-based settings, as well as other medical specialties, policy makers and insurance funds involved in the diagnosis and treatment of patients with AK and cSCC. A separate guideline exists for patients and their relatives. In this part, we will address aspects relating to epidemiology and etiology, diagnostics, surgical and systemic treatment of cutaneous squamous cell carcinoma (cSCC), surveillance and prevention.

Common diseases of the nail: Diagnosis and therapy.

This review focuses on nail changes that do not belong to the group of benign or malignant nail tumors. These common afflictions of the nail include structural changes in and under the nail plate as well as inflammation around and in the nail bed. They include onychomycoses, nail psoriasis, onychodystrophies, subungual hematoma, paronychia, ingrown nails and pincer nails. Due to the peculiar anatomy and physiological growth conditions of the nail, the pathology does not necessarily stem from the site of the clinical problem and calls for careful inspection and interpretation.

Hygiene recommendations for outpatient dermatosurgery.

The German Infection Protection Act and country-specific laws demand appropriate measures to prevent nosocomial infections and propagation of pathogens, especially those with resistances. This also concerns outpatient surgery of the skin. Special focus is placed on hand hygiene, antiseptics, hygienic modes of operation and professional instrument reprocessing. Every dermatological institution that operates on an outpatient basis is obliged to organize and be responsible for its hygiene. The legal framework is regulated by various laws and regulations and must be observed.

[The dermatologist Edmund Lesser (1852-1918) : Teaching and learning in Leipzig]. / Der Dermatologe Edmund Lesser (1852­1918) : Lehren und Lernen in Leipzig.

Edmund Lesser was one of the most influential German dermatologists of his time. After the death of his academic teacher Oscar Simon in Breslau, the later director of the dermatology hospital at the Charité moved to Leipzig in 1882. At the University of Leipzig he quickly completed his habilitation in June of the same year and continued the course for dermatology and venereology started by Neisser. Later he also went into private practice, where he recruited patients for his lectures. In Leipzig Lesser also published his well-received handbook on skin diseases and venereology and organized the third meeting of the German Society of Dermatology in 1891. Despite his hope and his undisputable achievements, he was not granted professorship by the faculty of medicine in Leipzig. For this he had to become head of dermatology at the University of Bern in 1892. This manuscript deals with his ten important years in Leipzig as a prerequisite for his later merits in Berlin as well as the development of academic dermatology at the University of Leipzig.

[Fame alone is not enough : How the renowned discoverer Albert Neisser (1855-1916) came to academic honors in dermatology in Leipzig]. / Ruhm alleine reicht nicht : Wie der gefeierte Entdecker Albert Neisser (1855­1916) in Leipzig zu akademischen Weihen in der Dermatologie kam.

Despite his scientific achievements while still in medical school, Albert Neisser was not accepted into internal medicine. This was typical for this period, as Jewish doctors were not allowed into esteemed disciplines such as internal medicine and surgery. Due to his important discoveries as a resident in dermatology he rose to international fame; however, he had to move to Leipzig to boost his later career in Germany. This step has been somewhat neglected and is therefore the topic of this article.
