[Effects of the COVID-19 pandemic on inpatient dermatosurgery in Germany : Retrospective evaluation of the surgical cases from nine dermatology clinics]. / Auswirkungen der COVID-19-Pandemie auf die stationäre Dermatochirurgie in Deutschland : Retrospektive Auswertung der operativen Fälle aus neun Hautkliniken.

INTRODUCTION: Currently, only little data is available on the impact of the COVID-19 pandemic on inpatient dermatosurgical care in German dermatological clinics. METHODS: A retrospective analysis of all dermatosurgical cases that were treated in inpatient setting in nine German dermatological clinics in four federal states in 2019, 2020 and 2021 was performed. The diagnoses were recorded using the ICD-10 codes. In addition, demographic data such as age, gender and the length of inpatient stay were analysed. RESULTS: In 2019, 2020 and 2021, a total of 10,739, 9185 and 9828 dermatosurgical inpatients were treated respectively. Thus, the reduction of inpatient dermatosurgical cases was 14.5% in 2020 and 8.5% in 2021 compared to 2019. Inpatient surgical treatment of melanoma decreased by 10.1% of cases in 2020. This decrease was only 1.4% in 2021 compared to 2019. The number of inpatient surgeries performed for benign lesions such as melanocytic nevi or viral warts reduced sharply in both pandemic years. CONCLUSION: Our data show for the first time how inpatient care for the entire spectrum of dermatosurgical diseases developed during the COVID-19 pandemic in Germany. After the initial marked decline in inpatient dermatosurgical cases in 2020, there was less difference in 2021 compared to 2019. This trend can be interpreted as an indication that there is still a strong need for inpatient dermatosurgical care that cannot yet be met on an outpatient basis.

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.

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.

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.

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.

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.
