RESUMEN

Introduction Merkel cell carcinoma is an aggressive neuroendocrine tumor that is related to immunosuppression and the Merkel cell polyomavirus. It is more common on the head and neck and has been associated with other skin malignancies such as basal cell carcinoma, squamous cell carcinoma, and melanoma. However, there has never been a nationwide investigation that quantifies Merkel cell carcinoma's connection with these subgroups. Methods Utilizing the National Institutes of Health's All of Us open-access database, a retrospective study was conducted by filtering for Merkel cell carcinoma through the International Classification of Diseases, 9th and 10th Clinical Modification codes 209.* and C4A.*, respectively. This led to the inclusion of 41 patients in the study, with each instance compared to four control patients without merkel cell carcinoma, matched by age, race, and gender. The data's demographics and skin cancer co-morbidities were collected and evaluated with odds ratios and 95% confidence intervals using Wald's method. Results In patients with merkel cell carcinoma, a statistically significant gradient of increasing risk for developing basal cell carcinoma (Odds Ratio, 11.63; 95% Confidence Interval, 4.30-31.45; P < 0.0001), squamous cell carcinoma (Odds Ratio, 15.09; 95% Confidence Interval, 3.87-58.84; P = 0.0001), and melanoma (Odds Ratio, 27.94; 95% Confidence Interval, 3.26-239.48; P = 0.0024) was observed. The race/ethnicity demographics showed that 85.4% of the patients were white, and they were at the highest risk of developing merkel cell carcinoma. However, the study has limitations, such as the inability to identify the stage of merkel cell carcinoma among patients and the lack of consideration for other confounding variables. Conclusion The study examines the link between merkel cell carcinoma and other skin malignancies, underscoring the need for more national research to better understand the underlying causes that contribute to this link. The findings also indicate the possibility of sample bias in the All of Us database, emphasizing the need to assess the patient population's representativeness in such investigations.

RESUMEN

Background: The number of Mohs stages needed to remove a keratinocyte carcinoma affects resource use, expenses, and repair complexity. This study aimed to identify clinicopathological predictors associated with increased or decreased stages and areas for further research. Methods: A retrospective review was conducted from a single private practice with two Mohs surgeons of 2788 consecutive Mohs cases between January 2017 and December 2021, analyzing the average number of stages taken versus national norms (P = 0.21) and subgroups using unpaired t tests (*<0.05). Results: Several tumor features were significantly associated with fewer stages: squamous cell carcinomas, Mohs appropriate use criteria score of 7 or 8, preoperative size <0.25 cm2, tumors on the lips and extremities (including hands/fingers), and smoking. Clinicopathological features significantly associated with more stages included Mohs appropriate use criteria score of 9, recurrent skin cancers, basal cell carcinomas, tumor size of 2.25-3.99 cm2, cancers on ears, solid organ transplant patients, treatment delays >180 days, and patients ≥90 years old. Conclusions: Significant predictors exist for both increased and decreased numbers of Mohs micrographic surgery stages required to eradicate a tumor, which may help Mohs surgeons facilitate, plan, and allocate resources more effectively. Areas for further research in Mohs micrographic surgery are identified.

RESUMEN

Longitudinal erythronychia (LE) is a term for red streaks in the nail which can be caused by a range of diseases. The specific type of longitudinal erythronychia can correlate with certain associated conditions making it important to properly categorize when discovered. A 71-year-old Hispanic male presented to the clinic with a type 1A LE associated with subungual keratosis that had been asymptomatic for approximately 12 months. The patient denied injury, pain, cold sensitivity, or cosmetic distress. The working diagnosis was squamous cell carcinoma in situ (SCCIS) vs. onychopapilloma or glomus tumor. A 4mm punch biopsy from the distal nail matrix was performed, and dermatopathology revealed that the LE was secondary to a wooden splinter. After a literature review, it was discovered that this is the first confirmed case of LE secondary to a splinter. Future providers should keep splinters as a potential differential diagnosis, especially as they evaluate LE, but ultimately all suspicious type IA lesions should be biopsied to rule out potential insidious pathologies, such as SCCIS and malignant melanoma.

RESUMEN

As value-based reimbursement continues to grow as a means of compensation in the US healthcare system, ensuring effective evaluation of patient care is becoming increasingly important. The aim of this study was to systematically collect and review data to identify potential patient bias based on a nonmodifiable patient characteristic, payer type, in patient satisfaction scores from an academic dermatology clinic setting. This retrospective study used Press Ganey self-reported, deidentified patient satisfaction surveys completed at Texas Tech University Health Sciences Center's outpatient dermatology clinic between January 1, 2010, and December 21, 2021, with a total of 21,408 surveys included in the study. The results found the self-pay/uncompensated group reported the highest mean satisfaction score (96.25%), followed by other government (94.76%), Medicare (94.34%), commercial (92.82%), workers' comp (88.10%), and Medicaid (82.78%). Analysis of variance resulted in an F value of 3.02 (P < 0.01). This study confirmed the results of existing research suggesting that payer class significantly impacts patient experience scores.

RESUMEN

Orthopaedic surgery is one of the more competitive specialties for medical students to pursue. Students often complete subinternship rotations to demonstrate skill, work ethic, and fit within a program. Away rotations were suspended during the COVID-19 pandemic. Methods: This investigation compared home and regional match rates before the pandemic to the match cycle of 2020-2021. Results: There was a statistically significant increase in students matching to their home program, and insignificant increase in regional matches. Conclusions: This increase is likely due in part to the familiarity of students to programs where they could still rotate during the pandemic. Level of Evidence: Level IV.

RESUMEN

Basal cell carcinoma (BCC), one of the most common malignancies, is rarely associated with follicular and apocrine differentiation patterns. This case presents a case of BCC with atypical gross presentation and features of aberrant differentiation. Clinicians should maintain a high level of clinical suspicion for BCC in atypical lesions.

RESUMEN

Nevus sebaceus is a congenital hamartoma associated with several secondary tumors. We report the case of a 19-year-old woman who presented with changes in a nevus sebaceus lesion on her parietal scalp, which was subsequently excised. Upon pathological examination, both basaloid hamartoma and syringocystadenoma papilliferum were noted within the specimen, which is rare. The primary treatment modalities for nevus sebaceus are either close clinical observation or surgical excision, but no definitive consensus exists on the excision timeline of nevus sebaceus.

RESUMEN

OBJECTIVE: Although various treatment modalities exist for skin cancer care, Mohs micrographic surgery (MMS) is one of the most effective and cosmetically sensitive surgical techniques. The readability of online informational materials specifically related to MMS postsurgical wound care is extremely relevant for patients given the high rates of skin cancer in the US and the number of patients utilizing the internet for information. METHODS: Investigators conducted Google searches to evaluate the current state of readability on MMS postsurgical wound care using the specific keywords "healing after Mohs surgery" and "wound care Mohs surgery." The readabilities of individual websites were analyzed using the WebFX online software. Health-specific click-through rate was used to select the number of samples assessed. RESULTS: Based on the 33 unique websites evaluated, the aggregate readability of online MMS postsurgical wound care materials was 11.3, corresponding to an 11th-grade reading level by US standards. CONCLUSIONS: Although this level of readability is an improvement in online MMS postsurgical wound care information relative to prior literature, there is still considerable work to be done by the dermatologic community in improving the readability of online patient materials regarding MMS.

RESUMEN

Lichen nitidus is a generally asymptomatic disease identified by shiny, flesh-colored papules that are often limited to the trunk, upper limbs, and genitalia. Here, we describe a generalized presentation of lichen nitidus in a 6-year-old girl with Down syndrome. Lichen nitidus shares a known association with Down syndrome, and several case studies document patients with Down syndrome developing generalized lichen nitidus. The extensive nature of our patient's lichen nitidus, as well as the uncommon distribution, particularly on the face, adds to the currently limited primary literature on this subject.

RESUMEN

Disseminate and recurrent infundibulofolliculitis (DRIF) is a rare form of folliculitis characterized by multiple papules widely distributed on the trunk and extremities. We present a 37-year-old man with confirmed DRIF complicated by transfollicular elimination of the sebaceous unit, an additional finding of DRIF that has rarely been reported.

RESUMEN

OBJECTIVES: Understanding vaccine intentions and attitudes of health professionals is critical as the Pfizer-BioNTech and the Moderna COVID19 vaccines are being administered throughout the United States. This study estimates the level of vaccine hesitancy at a health sciences center in West Texas prior to the distribution of the vaccines. METHODS: An analytical cross-sectional study was performed via anonymous Qualtrics survey administered to approximately 4500 faculty, staff, postdoctoral research associates/medical residents, and employees at a multi-campus health sciences university in the United States. Respondents were asked demographic questions and intention to receive the vaccine. Factors associated with the intention to receive a vaccine were determined using logistic regression analysis. RESULTS: A total sample of 2258 subjects were evaluated (50.0% response rate). Among all respondents, 64.6% reported that they would probably or definitely receive the COVID-19 vaccine. Men had higher levels of intention to receive the vaccine (OR = 2.11, 95% CI 1.64-2.71); respondents who indicated yearly influenza vaccines are necessary were also more likely to receive the vaccine (OR = 6.04, 95% CI 4.70-7.75). Eighty-three percent of faculty and 56% of the staff reported intention to receive the vaccine. Respondents who had previously tested positive for COVID-19 reported more interest in receiving the vaccine (58.5% yes vs 41.5% no). CONCLUSION: In this study, the intention to receive the COVID-19 vaccination at a United States health sciences center falls below the necessary herd immunity estimates. Public health initiatives must be developed to decrease vaccine hesitancy, especially among health professionals.

RESUMEN

Cutaneous injury and irritation among health care workers has substantially risen during the COVID-19 pandemic. In a field already laden with skin-induced injury and irritation due to high levels of handwashing and glove wearing, increases have been reported in handwashing-induced xerosis, irritant dermatitis, and contact dermatitis from N95 respirators and other surgical masks. Masks, goggles, face shields, and gloves all potentially create abrasions from long hours of use, leading to itching, pain, and aggravation of underlying skin conditions. Personal protective equipment (PPE)-related skin injury can be serious, and the American Academy of Dermatology has released recommendations on preventing and treating occupationally induced dermatologic conditions during the COVID-19 pandemic. These are reviewed and discussed in conjunction with overarching guidelines for mitigating the spread of the virus.

RESUMEN

Small-incision lenticule extraction (SMILE) is a stromal based, flapless, minimally invasive form of laser vision correction for the treatment of myopia and myopic astigmatism. SMILE surgery is a more technical procedure compared with other refractive surgeries and generally has a longer skill mastery acquisition period. Thus far, no new stabilization devices or techniques have been proposed. To rectify this, a new distal corneal countertraction device for SMILE surgery, the Monson SMILE Fixation Device, is introduced. This device provides reliable corneal and globe stabilization during delamination and lenticular dissection. It may minimize tissue distortion and manipulation, simplify lenticule dissection, and may decrease operation times and improve cosmesis. Countertraction can also easily be adjusted throughout the procedure.
