BACKGROUND: Paget’s disease of the breast is rare. The National Cancer Database (NCDB) is one of the largest tumor databases in the United States. METHODS: We queried the NCDB to identify male and female patients with Paget’s disease of the breast who were treated from January 1, 2004, through December 31, 2015. No age limitations were applied. Descriptive statistical analysis and survival analysis were performed. RESULTS: We analyzed the demographic, disease, and treatment characteristics of 7,191 patients with Paget’s disease of the breast. The median (range) age was 64 (20–90) years. Only 2.1% of patients were men, and 85.4% were white. The most common treatment was complete mastectomy (65.3%), followed by partial mastectomy (30.3%). Tumor destruction was performed in 0.1% of patients, and 4.3% of patients did not undergo any surgery. We examined survival in the subset of 6,864 patients who were treated surgically with complete mastectomy or partial mastectomy. The 5-year survival rate after surgery was 82.5% (95% CI, 81.1%–83.9%). Factors associated with shorter survival were older age, black race/ethnicity, higher tumor grade, regional lymph node metastasis, higher cancer stage, metastatic cancer, and larger tumor size. CONCLUSIONS: Paget’s disease of the breast usually affects patients older than 60 years, and the most common treatment is complete mastectomy. The 5-year overall survival rate of patients with Paget’s disease of the breast is greater than 80% but is lower among older and black people.

Abstract Background Lymphedema is an accumulation of protein-rich fluid in the interstitial spaces resulting from impairment in the lymphatic circulation that can impair quality of life and cause considerable morbidity. Lower extremity lymphedema (LEL) has an overall incidence rate of 20%. Conservative therapies are the first step in treatment of LEL; however, they do not provide a cure because they fail to address the underlying physiologic dysfunction of the lymphatic system. Among several surgical alternatives, lymphaticovenous anastomosis (LVA) has gained popularity due to its improved outcomes and less invasive approach. This study aims to review the published literature on LVA for LEL treatment and to analyze the surgical outcomes. Methods PubMed database was used to perform a comprehensive literature review of all articles describing LVA for treatment of LEL from Novemeber 1985 to June 2019. Search terms included “lymphovenous” OR “lymphaticovenous” AND “bypass” OR “anastomosis” OR “shunt” AND “lower extremity lymphedema.” Results A total of 95 articles were identified in the initial query, out of which 58 individual articles were deemed eligible. The studies included in this review describe notable variations in surgical techniques, number of anastomoses, and supplementary interventions. All, except one study, reported positive outcomes based on limb circumference and volume changes or subjective clinical improvement. The largest reduction rate in limb circumference and volume was 63.8%. Conclusion LVA demonstrated a considerable reduction in limb volume and improvement in subjective findings of lymphedema in the majority of patients. The maintained effectiveness of this treatment modality in long-term follow-up suggests great efficacy of LVA in LEL treatment.

Abstract Background Chronic tenosynovitis of the upper extremities caused by Mycobacterium kansasii (M. kansasii) is uncommon, but symptoms may overlap with other more common diseases. Late diagnosis and treatment can lead to disfiguration of structures and rupture of tendons, resulting in worse cosmetic outcomes after reconstruction. Methods We present a clinical case and literature review of M. kansasii in patients with chronic tenosynovitis of upper extremities. PubMed was queried for cases of upper extremities tenosynovitis caused by M. kansasii. The keywords “M. kansasii,” “tenosynovitis” and synonyms were used for search in different combinations. Manuscripts, with no specific data or another condition, where the infection was not located in the upper extremities, were reviews, or not in English, were excluded from the study. Results We described 23 reported cases of tenosynovitis of the upper extremity caused by M. kansasii. An immunosuppressed state was present in eight (34.8%) cases, and 12 (52.2%) patients received immunosuppressive treatment. A long-time period between the first appearance of symptoms and the definitive diagnosis was identified (median: 7 months, interquartile range: 9). The most frequent symptoms were local swelling (65.2%), pain (56.5%), mass effect (26%), and stiffness (13%). Tendon rupture was found in three (13%) patients as a complication of the disease. Moreover, seven (30.4%) patients underwent previous surgeries to try to relieve the symptoms before definitive diagnosis was achieved. Conclusion M. kansasii is an important differential causal pathogen for tenosynovitis of the upper extremities. Although rare, raising awareness about this infectious disease is imperative to avoid inadequate management and hazardous aesthetic sequelae.

Background: Histoplasmosis of the upper extremities is extremely rare, and there is no consensus in its management. The aim of this study was to present a case report and literature review of histoplasmosis in the upper extremities to provide the best treatment recommendation and to increase awareness of this disease. Methods: A systematic review of the literature was performed in PubMed, MEDLINE, and EMBASE databases with the search terms “(Tenosynovitis AND histoplasmosis)” OR “(Upper limbs AND histoplasmosis)” OR “(Upper extremities AND histoplasmosis)” OR “((finger OR arm OR hand OR forearm OR wrist) AND histoplasmosis).” Manuscripts were included in the study if they described diagnosis of histoplasmosis in the bone, joint, synovia, or tendons of the upper extremities. Results: In all, 14 manuscripts and 15 cases of histoplasmosis of the upper extremities from 1992 to 2015 met the inclusion criteria. Eight (53.3%) patients were diagnosed with tenosynovitis, 5 (33.3%) with osteomyelitis, 1 (6.7%) with carpal tunnel syndrome, and 1 (6.7%) with joint wrist abscess. Immunosuppression, travel history, previous diagnosis with histoplasmosis, and persistent symptoms may suggest infectious causes. Surgery and medical treatment together are recommended to optimize outcomes compared with single treatment alone. Conclusions: Histoplasmosis of the upper extremities may have various clinical presentations, including tenosynovitis, osteomyelitis, carpal tunnel syndrome, and joint wrist abscess. The type of surgical approach may depend on the etiology of disease. Increased awareness and knowledge of the clinical signs, symptoms, and effective treatment modalities will help decrease possible complications, such as tendon rupture and functional impairment of the upper extremities.

Background Artificial Intelligent Virtual Assistants (AIVA) is a segment of artificial intelligence that is rapidly developing. However, its utilization to address patients' frequently asked questions remains unexplored. Methods We developed an AIVA to answer questions related to 10 frequent topics asked by plastic surgery patients in our institution. Between July 27, 2018, and August 10 of 2018, we recruited subjects with administrative positions at our health care institution to chat with the virtual assistant. They asked, with their own words, 1 question for each topic and filled out a satisfaction questionnaire. Postsurvey analysis of questions and answers allowed assessment of the virtual assistant's accuracy. Results Thirty participants completed the survey. The majority was female (70%), and the mean age was 27.76 years (SD, 8.68 [19–51] years). The overall accuracy of the plastic surgery AIVA was 92.3% (277/294 questions), and participants considered the answer correct in 83.3% of the time (250/294 answers). Most of the participants considered the AIVA easy to use, answered adequately, and could be helpful for patients. However, when asked if this technology could replace a human assistant, they stayed neutral.
