- Abstract
Background: Exogenous artifacts can interfere with accurate histologic tissue evaluation on frozen sections during Mohs micrographic surgery (MMS). Mohs surgeons should be aware of these anomalies to avoid potential misdiagnoses., Objective: To review exogenous artifacts encountered in frozen tissue pathology during MMS., Methods: A literature search was conducted in PubMed to identify studies reporting on exogenous artifacts encountered during MMS and a list of previously described exogenous artifacts was compiled. A retrospective examination of frozen histology slides from recent Mohs cases at the authors' institution was performed to obtain illustrative examples of these artifacts, supplemented by formalin-fixed paraffin-embedded samples when frozen examples could not be found., Results: Exogenous artifacts represent foreign bodies that have been externally introduced into the skin or artifacts resulting from other external factors. If frozen section evaluation is inaccurate, overdiagnosis can occur during MMS, resulting in unnecessary layers, larger margins, and more complex reconstructions. These exogenous tissue changes can mimic inflammatory processes and melanocytic or keratinocyte malignancies on histology., Conclusion: Exogenous artifacts are common findings during margin assessment in Mohs micrographic surgery. The resulting histological findings can be confusing but correlating them with the clinical and surgical history often reassures surgeons. Recognizing these artifacts facilitates accurate diagnosis and promotes optimal patient care., (Copyright © 2024 by the American Society for Dermatologic Surgery, Inc.

- Abstract
Background: Patients are often advised to keep the initial postoperative dressings dry and undisturbed for 24 to 72 hours. However, these requirements may result in significant disruption of patients' activities of daily living, such as bathing, leisure, and exercise., Objective: Compare standard management of keeping wounds dry and covered (48 hours) with early (6 hours) postoperative water exposure., Methods: Investigator-blinded, randomized (1:1), controlled trial evaluating rate of infection and additional outcomes of interest., Results: Overall, 437 patients were randomized to either the early (6-hour) water exposure (n = 218) intervention group or the standard cohort (n = 219). The incidence of culture-proven infection in the intervention group (1.8%) was similar to the standard group (1.4%) (P > .99). There was also no difference in rates of bleeding or bruising. Scar assessment using the Patient and Observer Scar Assessment Scale revealed similar scar outcomes., Limitations: Single site, academic center., Conclusion: Surgical wounds can be allowed to get wet in the immediate postoperative period with no increased incidence of infection or other complications and with similar cosmesis., Competing Interests: Conflicts of interest Dr Kirby has served as a consultant for AbbVie, Incyte, Janssen, Novartis, and UCB; has received honoraria from AbbVie, Incyte, InsMed, and Viela Bio; and has served on the speakers bureau for AbbVie., (Copyright © 2024 American Academy of Dermatology, Inc.

- Abstract
Mycosis fungoides (MF) is a slowly progressive form of cutaneous T-cell lymphomas (CTCL). MF is classified into 4 subtypes including folliculotropic MF (FMF). Infiltration of both hair follicles and eccrine glands is included in the FMF classification and designated as syringotropic MF (STMF), an exceedingly rare form of CTCL. We report an additional case of STMF. The clinical course of syringotropic CTCL is more benign than FMF, suggesting that despite similar clinical presentations, they are molecularly distinct diseases. Clinical characteristics can help differentiate STMF from FMF. Skin-directed therapies are less effective in STMF than FMF. With distinct clinical characteristics, histopathologic findings, and disease course, syringotropic CTCL should be considered a subtype entity in the spectrum of adnexotropic MF.

- Abstract
In the past two decades, endovascular aortic repair (EVAR) of abdominal aortic aneurysm (AAA) has become the first line treatment for infrarenal AAA repair in many countries. While short-term results are good, concerns have been raised about long-term durability. Changes in aortoiliac anatomy, especially at the landing zones, could play a role in EVAR failure over time. The current study aimed to determine certain morphological changes in the distal iliac landing zone after EVAR implantation, as well aspossible risk factors associated with iliac sealing failure. In a retrospective analysis of a tertiary single-centre registry, including patients treated with EVAR between January 2008 and July 2018, clinical follow-up data were assessed, and computer tomography (CT) imaging was evaluated regarding morphological changes in the iliac anatomy during follow-up. For clinical analysis all patients with a minimum follow-up of one year were included; for morphological analysis of iliac anatomy all patients with available CT follow-up of a minimum of one year and a minimum of two CT scans were included. Overall, 127 out of 241 treated patients (92.1% male) were included in the clinical follow-up. Complete CT imaging of 99 iliac arteries in 55 patients was available for morphological analysis. Median postoperative follow-up (FU) for these patients was 33 months (IQR 31; min−max: 12−124). Incidence of type 1b endoleak was 3% but iliac limb detachment from the vessel wall was seen in 18.2% of the target vessels. There was a significant difference in oversizing in iliac limbs with detachment (median 13.9%, IQR 23.1) vs. without detachment (median 23.1%, IQR 19.1) (p = 0.034). Iliac arteries at the landing zone showed a significant diameter increase independent of an endoleak presence (overall cohort median diameter increase at one year 23.1 mm; at two years 0 mm; at three years 4.9 mm). Iliac arteries with detachment (median 14.4%; IQR 23.9) showed a significantly higher diameter increase at the landing zone after four years compared to arteries without detachment (median 5.3%; IQR 9) (p = 0.042). Oversizing correlated positively with an iliac diameter increase at the landing zone over time (3 m: p= 0.001; one year: p < 0.001; two years: p < 0.001; three years: p = 0.006). Older patients showed a significantly lower diameter increase at the distal landing zone over time than younger patients in the first two years after EVAR (p < 0.001/r = −0.606 after two years). In the current study, iliac limb oversizing was associated with increased dilatation of the distal landing zone during a three-year follow-up, while iliac limb detachment was observed less often. An older age was inversely associated to the iliac diameter increase. Future studies should clarify the association between stent graft oversizing, age, and changes in the iliac anatomy in order to identify parameters that affect EVAR durability.

- Abstract
Regeneration after severe peripheral nerve injury is often poor. Knowledge of human nerve regeneration and the growth microenvironment is greatly lacking. We aimed to identify the regenerative proteins in human peripheral nerve by comparing the proteome before and after a transection injury. In a unique study design, we collected closely matched samples of naïve and injured sural nerve. Naïve and injured (two weeks after injury) samples were analyzed using mass spectrometry and immunoassays. We found significantly altered levels following the nerve injury. Mass spectrometry revealed that injury samples had 568 proteins significantly upregulated and 471 significantly downregulated compared to naïve samples (q-value ≤ 0.05 and Z ≥ |2| (log2)). We used Gene Ontology (GO) pathway overrepresentation analysis to highlight groups of proteins that were significantly upregulated or downregulated with injury-induced degeneration and regeneration. Significant protein changes in key pathways were identified including growth factor levels, Schwann cell de-differentiation, myelination downregulation, epithelial-mesenchymal transition (EMT), and axonal regeneration pathways. The proteomes of the uninjured nerve compared to the degenerating/regenerating nerve may reveal biomarkers to aid in the development of repair strategies such as infusing supplemental trophic factors and in monitoring neural tissue regeneration., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2022 Chau et al.

- Abstract
Background: The COVID-19 pandemic has shifted the dynamics of health care and neurosurgical practice. Elective surgeries were suspended for 8 weeks in Kentucky. Our objective was to determine if telehealth (TH) visits could be sustained as an alternative to in-person visits., Methods: Deidentified data on TH usage, in-person clinic visits, and inpatient and neurosurgical case volumes from March 2, 2020 to June 26, 2020 were obtained for retrospective analysis., Results: TH use increased soon after the case suspension started and then decreased to little usage. The number of in-person visits were significantly lower during elective case suspension compared with when cases were resumed. Twenty-five percent of all visits during the suspension were conducted using TH. Thirty-nine percent of TH-visit patients were new patients, 11% were preoperative, 10% were postoperative, and 39% were other existing patients. Forty-eight percent of TH visits resulted in a later in-person clinic visit. After the suspension, in-person visits rebounded to 98% of the prepandemic numbers and TH visits were low., Conclusions: TH visits were challenging due to the need for in-person physical examinations in neurosurgery. TH temporarily accommodated patient needs during the pandemic but could not totally replace in-person visits and was not sustained after 3.5 months of use. Video TH visits worked well for nonurgent issues, such as minor visual examinations. Our findings could help guide the implementation of TH should similar circumstances arise again., (Copyright © 2021. Published by Elsevier Inc.)
