Neonatal Curettage of Large to Giant Congenital Melanocytic Nevi Under Local Anesthetic: A Case Series With Long-Term Follow Up.

BACKGROUND: Neonatal curettage of large to giant congenital melanocytic nevi (L-GCMN) is a simple, minimally invasive procedure typically performed within the first 2 weeks of life. OBJECTIVES: To retrospectively review our experience with serial curettage of L-GCMN in the neonatal period performed under local anesthesia and their long-term outcomes. METHODS: Curettage was performed by a single pediatric dermatologist on nine neonates with L-GCMN under local anesthetic and with oral analgesia between 2002 and 2016 in Red Deer, Alberta, Canada. Patient charts were reviewed retrospectively to assess patient and procedure characteristics, tolerability, safety, cosmetic and functional outcomes, and malignant transformation. RESULTS: Patients were treated with an average of 6 curettage sessions (range 3 to 15) to remove the majority or entirety of the nevus. All patients tolerated local anesthesia well. The most common adverse event of the procedure was transient neutropenia. Two patients developed positive bacterial cultures without clinical signs of infection, treated with antibiotics. All curetted specimens demonstrated benign pathology. Patients were followed annually thereafter, for an average of 6 years. Eight patients with L-GCMN of the trunk had minimal to partial repigmentation with good cosmetic outcome. One patient had recurrence of a facial nevus. None of the patients developed cutaneous malignant melanoma. CONCLUSIONS: Curettage appears to be a safe and effective treatment option for select cases of L-GCMNs of the trunk. We do not recommend the procedure for face or scalp CMN. This procedure can be performed under local anesthesia with serial curettage to avoid potential risks of general anesthesia.

Cutaneous HPV16 and p16 Positive Basaloid Squamous Cell Carcinoma with Brain Metastasis: A Case Report.

Basaloid squamous cell carcinoma is an infiltrative and aggressive variant of squamous cell carcinoma with basaloid features. Primary skin-derived basaloid squamous cell carcinoma is rare. Basaloid squamous cell carcinoma is commonly observed in the oropharyngeal and anogenital regions and is associated with high-risk human papillomavirus. We report a case of primary basaloid squamous cell carcinoma overlying the right scapula with metastasis to the regional lymph nodes and brain despite surgical resection and adjuvant chemoradiation. Histopathologic investigations of high-risk cutaneous squamous cell carcinoma do not routinely involve human papillomavirus testing. In contrast, oncogenic human papillomavirus and p16 are screened in head and neck squamous cell carcinoma for prognostication. Since the patient presented with an aggressive variant of squamous cell carcinoma and distal metastasis despite standard therapies, human papillomavirus testing was performed. P16, a surrogate marker for human papillomavirus infection and specifically HPV16 was identified in the tumor. This is a unique report of HPV16 in primary cutaneous basaloid squamous cell carcinoma with distal brain metastasis.

Cryosurgery + 5% 5-Fluorouracil for Treatment of Superficial Basal Cell Carcinoma and Bowen's Disease [Formula: see text].

BACKGROUND: Superficial basal cell carcinoma (sBCC) and squamous cell carcinoma in situ (SCCis) are 2 types of nonmelanoma skin cancers (NMSCs) that are amenable to treatment with topical 5-fluorouracil, cryosurgery, or topical imiquimod, among other destructive and surgical modalities. There are few studies examining the effectiveness of combination therapy with 5% 5-fluorouracil and cryosurgery for the treatment of sBCC and SCCis. OBJECTIVES: Our objective was to study the clinical cure rate achieved with the regimen of cryosurgery and a 3-week course of 5% 5-fluorouracil in the treatment of biopsy-proven sBCC and SCCis. METHODS: A retrospective chart review of patients treated with cryosurgery and a 3-week course of 5% 5-fluorouracil was performed. Immunocompetent patients with biopsy-proven sBCC or SCCis who completed the treatment and attended a follow-up appointment at 6 months were included in the study. RESULTS: On clinical examination, 30 sBCC lesions of the 34 that were assessed and 31 SCCis lesions of the 33 that were assessed demonstrated no evidence of recurrence. The clinical cure rates were found to be 73% (sBCC) and 82% (SCCis), with the inclusion of patients that were lost to follow-up. CONCLUSIONS: This approach may represent a suitable option for select patients for the treatment of SCCis. Further studies with a longer follow-up duration, documentation of histologic cure, and tolerability of this regimen for SCCis are needed. The effectiveness of cryosurgery and 5-fluorouracil for sBCC requires further study.

Yellow Nail Syndrome Presenting With a Pericardial Effusion: A Case Report and Review of the Literature.

Yellow nail syndrome (YNS) is a constellation of clinical findings including at least 2 of the 3 features of thickened yellow nails, respiratory tract involvement, and lymphedema. We report the case of a middle-aged man presenting with dystrophic, thickened yellow nails; an idiopathic pericardial effusion in the absence of pleural effusion(s); and unilateral apical bronchiectasis found on computed tomography of the chest. This represents a unique presentation of YNS as the first report of a patient with YNS and a pericardial effusion in the absence of pleural effusions and lymphedema and is the 11th case report of YNS with pericardial effusion.

Coexistent rheumatoid arthritis and gout: a case series and review of the literature.

Since 1964 to present, there have been more than 33 cases of concomitant rheumatoid arthritis (RA) and gout reported in the literature. The objective of this study is to present a case series of patients with coexistent rheumatoid arthritis and gout and to provide a review of the literature. A retrospective review of a rheumatology patient database at the University of Alberta was performed (2004-2017). Patient charts were reviewed and the 1987 ARA Revised Classification Criteria for RA and 1977 ARA Classification Criteria for gout were applied to each patient. For gout, positive monosodium urate crystals on synovial fluid analysis, synovial/node biopsy, or positive dual-energy CT-gout protocol were used to satisfy the diagnosis of gout if available. Thirteen patients were identified with both RA and gout (nine men and four women). The mean age was 68.6, while the mean age at the onset of first disease was 55.3 and onset of second disease was 64.4. Eight patients were initially diagnosed with RA and subsequently developed gout, while five patients were first diagnosed with gout and subsequently developed RA. Standard radiographs showed findings characteristic of RA and gout in affected joints. In joints affected by both diseases, the gout findings predominated and the RA changes were milder. Rheumatoid arthritis and gout do coexist in the same patient, contrary to popular belief. Understanding that both conditions can occur concomitantly is necessary for clinical awareness, especially in patients with polyarticular disease that is difficult to treat.

Conversion rates of abstracts presented at the Canadian Rheumatology Association Annual Meetings into full-text journal articles.

Dissemination of research studies is important for research ideas to be transformed from initial abstracts to full publications. Analyses of the scientific impact and publication record of the Canadian Rheumatology Association (CRA) Annual meeting have not been previously described. This study determines the publication rate of abstracts presented at the CRA Annual Meetings 2005-2013 to full-text journal articles and the factors associated with publication. Program records of previous CRA meetings from 2005 to 2013 were obtained. Abstracts were searched for corresponding full-text publication in Google Scholar and PubMed using a search algorithm. Abstracts and subsequent published articles were evaluated for type of abstract, time to publication, study type, publishing journal, and journal impact factor. A total of 1401 abstracts were included in the study, 567 of which were converted to full publications. The average time to publication was 19.7 months, with 89% of abstracts published within 3 years of being presented. Eighty-three percent of abstracts were clinical in nature, and 58% of published studies were observational in design. Articles were published in a wide range of journals, with the top publisher being the Journal of Rheumatology (31%). Average time to publication was 19.7 months. Eighty-six percent of articles had a Journal Impact Factor > 2. Overall, 40.5% of abstracts presented at the CRA Annual Meetings 2005-2013 were published. Further research is needed to determine barriers and reasons for abstracts not being published as full-text articles.
