different host types and can be improved. CLINICAL RELEVANCE The relevance and impact of a clinical observership experience in North America for a practicing orthopaedic surgeon from an LMIC need to be explored further.BACKGROUND Coronavirus disease 2019 (COVID-19) broke out in Wuhan, the People's Republic of China, in December 2019 and now is a pandemic all around the world. Some orthopaedic surgeons in Wuhan were infected with COVID-19. METHODS We conducted a survey to identify the orthopaedic surgeons who were infected with COVID-19 in Wuhan. A self-administered questionnaire was distributed to collect information such as social demographic variables, clinical manifestations, exposure history, awareness of the outbreak, infection control training provided by hospitals, and individual protection practices. To further explore the possible risk factors at the individual level, a 12 matched case-control study was conducted. RESULTS A total of 26 orthopaedic surgeons from 8 hospitals in Wuhan were identified as having COVID-19. The incidence in each hospital varied from 1.5% to 20.7%. The onset of symptoms was from January 13 to February 5, 2020, and peaked on January 23, 8 days prior to the peak of the public epidemic. The sEVEL OF EVIDENCE Diagnostic Level IV.

However, distinguishing between metastatic melanoma cells and clusters of benign melanocytic nevus cells is not always straightforward. When morphologic hematoxylin and eosin interpretation alone is not sufficient, additional hematoxylin and eosin sections and immunohistochemical (IHC) studies may be beneficial. This review and small cases series of 3 diagnostically challenging melanocytic sentinel lymph node cases highlights the IHC approach to evaluate intraparenchymal nodal melanocytic nevi, coexistent metastatic melanoma with adjacent melanocytic nevi cells, and nodal blue nevi. In challenging cases, cytological morphology of the melanocytes, location within the lymph node, and IHC studies may assist in diagnosis. If these tools yield conflicting results, expert opinion is recommended.Eccrine syringofibroadenoma (ESFA) is a cutaneous proliferation of eccrine ducts, mainly encountered in association with other dermatoses or skin tumors. Although a benign condition, either considered as a hamartoma or a reactive hyperplasia rather than a real neoplasm, some evidence suggests that longstanding ESFA can undergo malignant change. The recognition of such opportunity could have important therapeutic implications. We present a case of ESFA showing areas of carcinomatous transformation, discussing its morphological and immunohistochemical findings.Proliferating onychomatricoma is a new challenging variant of onychomatricoma that can clinically and histologically mimic squamous cell carcinoma/onycholemmal carcinoma. This is a retrospective case series study of the clinicopathologic and dermoscopic features of 6 patients with a pathologic diagnosis of proliferating onychomatricoma, which was conducted in the dermatology and dermatopathology departments of 2 university hospitals and a private nail's dermatology consultation. The clinical, histological, and immunohistochemical features and follow-up of 6 patients with proliferating onychomatricoma were analyzed; we compare our finding with 6 cases of conventional onychomatricoma. The female-to-male ratio was 11 with involvement of fingers in 4 and toe in 2. Among the symptoms were verrucous lesion simulating squamous cell carcinoma, nail thickening, periungual erythema, and pain; symptom duration ranged from 5 to 8 years. Clinical, dermoscopical en face free-margin view, and nail-clipping histologic findinributes as free-edge honeycomb-like cavities associated with conventional OM are well established and permit a diagnosis of OM without an invasive nail biopsy. The free-edge wall-like pattern is a distinct new dermoscopic and nail-clipping pattern that should raise for the others onychogenic neoplasms and prompt the clinician to obtain a biopsy specimen. In addition to proliferating OM, the differential diagnosis includes a micropapilliferum variant of OM, onychocytic matricoma, and onychocytic carcinoma.PURPOSE The purpose of this study was to describe adolescents' perception of birth within the first 72 hours postpartum. STUDY DESIGN &amp; METHODS A thematic analysis using qualitative data captured via one overarching question about labor expectations as part of a larger, parent quantitative study exploring psychological birth trauma. RESULTS Forty-two percent (n = 128) of adolescents ages 13 to 19 in the original study responded in writing to one overarching question concerning birth expectations. Four major themes were identified including pain, support, personal control, and fear, with three subthemes. Pain was expressed as a primary theme for all age adolescents and had an impact on all other themes. Expressed fear was general and specific including a fear of dying that emerged as a subtheme along with labor information and emotions. CLINICAL IMPLICATIONS Lacking a positive birth experience has been linked with poor mental health outcomes (depression and posttraumatic stress) postpartum. Findings offer a guide for nurses and other healthcare providers to promote a positive birth experience for adolescents. Pain management is foremost to adolescents and requires healthcare providers' continued attention. Working together with adolescents to identify and monitor level of pain; assess support needs, feelings of loss of personal control, and signs or verbal expressions of fear; and offer ongoing information about labor progress and necessary procedures can help strengthen bonds between teens and their healthcare provider and create a positive birth experience.PURPOSE The purpose of this scoping review was to synthesize the literature on nursing support during the latent phase of the first stage of labor. In 2014, the definition of the beginning of active labor changed from 4 centimeters (cm) to 6 cm cervical dilation. More women may have an induction of labor based on results of recent research showing no causal increase in risk of cesarean birth with elective induction of labor for low-risk nulliparous women. Therefore, in-hospital latent phase labor may be longer, increasing the need for nursing support. DESIGN Scoping review of the literature from 2009 to present. METHODS We conducted the review using key words in PubMed, CINAHL, and Scopus. Search terms included different combinations of "latent or early labor," "birth," "support," "nursing support," "obstetrics," and "onset of labor." Peer-reviewed research and quality improvement articles from 2009 to present were included if they had specific implications for nursing care during the latent phase of labor. Articles were excluded if they were not specific to nursing, focused exclusively on tool development, or were from the perspective of pregnant women or providers only.
