Both nonsurgical and surgical modalities for the treatment of hair loss are being used by providers at an increasing rate worldwide. Men and woman are affected by hair loss, but the pathophysiology of the hair loss is thought to be different between sexes; therefore, gender must play a role in treatment decisions. Currently, there are 3 Food and Drug Administration-approved nonsurgical androgenetic alopecia treatments: minoxidil, finasteride, and low-light laser therapy. Platelet-rich plasma injections are showing promise as a single modality and as an adjunct to other nonsurgical and surgical treatments of androgenetic alopecia., (Copyright © 2022 Elsevier Inc.

Study Design: Systematic review of the literature., Objective: The goal of this study is to review the current literature on severe rhinophyma requiring operative management for significant cosmetic deformity or nasal obstruction. We aim to provide a treatment algorithm for the various surgical techniques employed in the treatment of severe rhinophyma., Methods: Independent searches of the PubMed and MEDLINE databases were performed. Articles from the period of 2010 to 2020 were collected. All studies which described surgical treatment of severe rhinophyma using the Boolean method and relevant search term combinations, including "rhinophyma," "severe," "operative" and "surgery" were collected., Results: A total of 111 relevant unique articles met criteria for eligibility analysis. Of these, 85 articles were deemed inappropriate for the literature review due to exclusion criteria. The remaining 26 articles were included in the literature review. Due to variability in study design and outcome measures, formal synthesis of data in the form of a meta-analysis was not possible., Conclusions: Severe rhinophyma may present a reconstructive challenge to reestablish normal contour and patent nasal airway. Significant deformity necessitates surgical correction. The present article reviews the current literature and provides a summary and stepwise explanation of established surgical techniques for addressing the cosmetic and functional deficits these patients encounter., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Background: Differences in approach to repair a specified defect after Mohs micrographic surgery (MMS) between specialties have not been previously examined., Objective: To assess the difference in frequency of which reconstruction repairs are selected after MMS, among Mohs surgeons and facial plastic surgeons (FPS), and evaluate whether the level of satisfaction with the final repair outcome differed between specialties., Materials and Methods: The study was approved by the Saint Louis University Institutional Review Board. A link to the survey was distributed to members of American College of Mohs Surgery (ACMS) and American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS), between January and May 2016., Results: The reconstructive procedure selected most often ("top choice") was not significantly different between Mohs surgeons and FPS for the majority of the images. There was no material difference in how dermatologists and FPS rate the aesthetic outcome of the 3 presented closure types, with the exception of one closure type-nose with graft., Conclusion: Mohs surgeons were found to more likely cluster around a single preference for their reconstruction technique compared with FPS, in which a higher percentage of surgeons also selected other options.

Background: Despite growing evidence on safe and feasible outpatient treatment for acute pulmonary embolism (PE), the majority of patients is still treated in an inpatient setting. This is probably due to a lack of clear guidelines on this subject., Objectives: To evaluate safety and patient reported outcome measures (PROM) on outpatient treatment of acute PE., Methods: We conducted a prospective cohort study. 250 patients presenting with acute PE and Pulmonary Embolism Severity Index (PESI) class I or II were enrolled. Safety of outpatient treatment was assessed by measuring all-cause mortality, recurrent venous thromboembolism (VTE) and episodes of relevant bleeding, with a follow-up period of four weeks and six months. Additionally, PROM's on outpatient treatment were evaluated by repeatedly measuring VAS-scores for pain and dyspnea during the recovery, and by assessing the improvement in SF-36 scores between admission and after six months., Results: We found an all-cause mortality rate of 0.4% (95% CI 0.07-2.23), rate of recurrent VTE of 0% (95% CI 0-1.51) and rate of relevant bleeding episodes of 6.4% (95% CI 3.98-10.14). VAS-scores improved significantly during the first 24-h after admission, and continued to improve significantly after five days of home treatment. SF-36 scores on 6 out of 8 domains improved significantly between admission and after six months., Conclusions: Our study shows that outpatient treatment is safe in selected low-risk patients based on their PESI score. Additionally, our data on patient reported outcome measures support the presumption of a good course of recovery during outpatient treatment., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Although bean bag guns are considered a "less-lethal" form of law enforcement, these blunt projectiles have risk. The purpose of this study was to perform a literature review of morbidity and mortality associated with less-lethal munitions and present a case report of a bean bag injury leading to a traumatic globe evisceration and skull base fracture. Patients presenting with bean bag gun associated injuries warrant a high clinical suspicion for injury to deeper structures.

Nasal reconstruction has been articulated in the literature since 700 B.C. when the earliest iteration of the forehead flap was described in the Indian medical treatise, the Sushruta Samhita. Since then it has evolved into the interpolated flap which has served as a powerful tool for facial reconstruction. The interpolated flap is constructed from nonadjacent donor tissue that has an inherent blood supply. It requires a multistaged approach and is best suited for reconstruction of large or deep defects of the nose. There are three types of interpolated flaps used for nasal reconstruction: the forehead, melolabial, and nasofacial interpolation flaps. The nose is the central feature of the human face and its placement is both aesthetic and functional. Any defects owing to accidental or iatrogenic trauma can cause physiologic and psychological injury to patients. This article aims to review the aforementioned flaps and give indications, contraindications, procedure details, and future directions of these flaps., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Skin grafts offer a dynamic repair option for nasal defects of appropriate size, depth, and location. Granulation and grafting can successfully be used as stand-alone reconstructive options or in conjunction with flap repair. This article reviews suitable indications for graft and granulation use in nasal repair to achieve optimum functional and esthetic outcomes., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Objectives: To determine if mandatory adherence to a diagnostic protocol increases the rate of computed tomography pulmonary angiographies (CTPAs) positive for pulmonary embolism (PE)-the so-called diagnostic yield. Further, we aim to identify factors associated with this diagnostic yield., Methods: We included all patients with suspected PE requiring CTPA from 9 January 2014 t0 3 June 2014. The requesting physicians were forced to follow diagnostic workup for PE by calculating a Wells score and, if necessary, determining D-dimer level. The percentage of positive CTPA scans was calculated and compared with our previous cohort (Walen et al. Insights Imaging 2014;5(2):231-236). Odds ratios were calculated as a measure of association between dichotomous variables and CTPA findings., Results: Of 250 scans, 74 were positive (29.6 % [95 % CI, 24.3-35.5 %]) and 175 were negative (70 %). The percentage positive scans increased with 6.6 % and the percentage negative scans decreased with 3.1 %. This change was statistically significant (p = 0.001). Independent clinical predictors of diagnostic yield were previous deep venous thrombosis (DVT) (OR, 3.22; p = 0.013) and clinical signs of DVT (OR, 2.71; p = 0.012). Chronic obstructive pulmonary disease (COPD) was negatively associated with PE (OR, 0.33; p = 0.045)., Conclusions: This study shows that mandatory adherence to a diagnostic protocol increases the yield of CTPA for PE in our centre., Main Messages: • Mandatory adherence to diagnostic protocol increases the yield of CTPA for PE • Previous DVT and signs of DVT were associated with a higher yield • No patients with a low Wells score and a low D-dimer had PE.

Background: Delayed diagnosis of pulmonary embolism (PE) is common because symptoms can be non-specific. The few studies that have investigated diagnostic delay have not taken into account the role of primary care physicians in the diagnostic process., Aim: To document and quantify the stages of diagnostic delay of PE and to identify clinical factors associated with this delay., Design and Setting: A retrospective cohort study conducted in Zwolle and its surroundings in the Netherlands., Method: Primary and secondary care records of all patients diagnosed with PE between January 2008 and December 2009 were reviewed for dates of symptom onset, date of presentation and diagnosis, and for clinical findings. Relationships between delay and clinical parameters were tested using multivariate regression analysis., Results: The 261 patients enrolled in the study had an average total delay of 8.6 days. Patient delay (4.2 days average) and delay in primary care (3.9 days) were the major contributors to this delay. Chest pain (odds ratio [OR] 0.51, 95% confidence interval [CI] = 0.28 to 0.92, P = 0.03) and symptoms of deep venous thrombosis (calf pain) (OR 0.49, 95% CI = 0.24 to 0.98, P = 0.05) were associated with an early diagnosis. Patient delay was shorter in patients with chest pain (OR 0.49, 95% CI = 0.25 to 0.95, P = 0.03) and longer in patients with dyspnoea (OR 2.95, 95% CI = 0.99 to 8.85, P = 0.05). In primary care, chest pain (OR 0.37, 95% CI = 0.17 to 0.84, P = 0.02) and rales (OR 0.22, 95% CI = 0.06 to 0.83, P = 0.03) were associated with an early referral, whereas comorbidity led to a delayed referral., Conclusion: This study shows that the diagnostic delay of PE is substantial, especially patient delay and delay in primary care. There is room to reduce this delay by increasing the awareness of both patients and GPs. Further research is needed on clinical factors that raise suspicion of PE in primary care., (© British Journal of General Practice 2016.)

Eyelid surgery consists of challenging reconstructive and cosmetic procedures. Because of the complex anatomy and corresponding vital functions of the upper and lower eyelids, the avoidance of eyelid complications is of vital importance. Complications after eyelid surgery include basic complications (infection, granuloma) and vision-threatening complications. Preoperative history, physical examination, surgical planning, and meticulous surgical technique must be undertaken to prevent complications after eyelid surgery. In addition, patient knowledge, expectations, and motivations must be determined before surgery is performed., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Importance Scalp reconstructions may be required after tumor resection or trauma. The inherent anatomy of the scalp presents challenges and may limit reconstructive options. Objective To describe and investigate the scalp rotation flap as a reconstructive technique for complex soft tissue defects. Design Retrospective case series with a mean follow-up of 13 months. Setting Tertiary academic center. Participants A total of 22 patients with large scalp soft tissue defects undergoing scalp rotation flap reconstruction. Interventions The flap is designed adjacent to the defect and elevated in the subgaleal plane. The flap is rotated into the defect, and a split-thickness skin graft is placed over the donor site periosteum. Main Outcomes and Measure Data points collected included defect size, operative time, hospital stay, and patient satisfaction with cosmetic outcome. Results Mean patient age was 71 years. Mean American Society of Anesthesiologist classification was 2.8. Mean defect size was 41 cm(2) (range: 7.8-120 cm(2)), and 19 of 22 defects resulted from a neoplasm resection. Mean operative time was 181 minutes, and mean hospital stay was 2.4 days. There were no intraoperative complications. Three patients with previous radiation therapy had distal flap necrosis. Twenty-one patients (95%) reported an acceptable cosmetic result. Conclusions and Relevance The scalp rotation flap is an efficient and reliable option for reconstructing complex soft tissue defects. This can be particularly important in patients with significant medical comorbidities who cannot tolerate a lengthy operative procedure.

Objective: To quantify the different stages of diagnostic delay of pulmonary embolism (PE) in patients and to identify other clinical factors associated with this delay., Design: Case series., Method: Medical records were reviewed for all patients diagnosed with PE in the period 1 January 2008 and 31 December 2009 in Isala Hospital in Zwolle (the Netherlands), and data was collated for: the dates of symptom onset, presentation to a GP, referral to secondary care, and diagnosis respectively. The relationship between diagnostic delay and other clinical parameters such as gender, age, risk factors, symptoms and co-morbidities was tested using multivariate logistic regression analysis., Results: For the 261 patients included in the analysis, the average total delay was 8.6 days. Patient delay (4.2 days average) and delay in primary care (3.9 days) were the major contributors to this delay. Chest pain and symptoms of deep venous thrombosis were associated with an early diagnosis. Patient delay was shorter in patients with chest pain and longer in patients with dyspnoea. In primary care, chest pain and rales were associated with an early referral, whereas the presence of co-morbidity led to a delayed referral. Delay in secondary care was shorter when the patient presented with dyspnoea., Conclusion: The diagnostic delay of PE is substantial, especially patient delay and delays originating in primary care. Further research is needed to identify clinical factors that raise suspicion of PE in primary care, to aid the development of improved diagnostic models.

Objectives: To determine the diagnostic yield of computed tomography scanning of the pulmonary arteries (CTPA) in our centre and factors associated with it. Differences between specialties as well as adherence to protocol were investigated., Methods: All patients receiving a first CTPA for pulmonary embolism (PE) in 2010 were included. Data about relevant clinical information and the requesting specialty were retrospectively obtained. Differences in diagnostic yield were tested using a chi-squared test. Independent predictors were identified with multivariate logistic regression., Results: PE on CTPA was found in 224 of the 974 patients (23 %). Between specialties, diagnostic yield varied from 19.5 to 23.9 % (p = 0.20). Independent predictors of diagnostic yield were: age, sex, D-dimer, cough, dyspnea, cardiac history, chronic obstructive pulmonary disease (COPD), atelectasis/consolidation, intrapulmonary mass and/or interstitial pulmonary disease on CT. Wells scores were poorly documented (n = 127, 13.0 %). Poor adherence to protocol was also shown by a high amount of unnecessary D-dimer values with a high Wells-score (35 of 58; 58.6 %)., Conclusions: The diagnostic yield of CTPA in this study was relatively high in comparison with other studies (6.7-31 %). Better adherence to protocol might improve the diagnostic yield further. A prospective study could confirm the independent predictors found in this study., Teaching Points: • Pulmonary embolism is potentially life-threatening and requires quick and reliable diagnosis. • Computed tomography of the pulmonary arteries (CTPA) provides this reliable diagnosis. • Several independent predictors of diagnostic yield of CTPA for pulmonary embolism were identified. • Diagnostic yield of CTPA did not differ between requesting specialties in our Hospital. • Better protocol adherence could improve the diagnostic yield of CTPA for pulmonary embolism.

Divided nevus, which is also known as "kissing nevus," "split ocular nevus" and "panda nevus" is a rare congenital dermatological abnormality that occurs on opposing margins of upper and lower eyelids. There is a paucity of literature on this rare anomaly, with most knowledge from this disease process derived from isolated case reports and series. The purpose of this study is to report a new case of divided nevus of the eyelid and to discuss the unique embryology, pathology, and potential treatment options for this rare entity. A systematic review of literature was performed of the English literature on PubMed and Medline with just under 150 cases reported in the literature. The vast majority of the divided nevi seen in this review were medium sized and of the melanocytic intradermal type. There were no described cases of malignant transformation in any of the documented cases. Numerous methods for reconstruction were described including the entire reconstructive ladder with both one and two staged approaches. In this review, we present basic guidelines to the reconstruction of these complicated defects, although ultimate treatment should be individualized and dependent on surgeon comfort., (Copyright © 2013 Elsevier Inc.

Two major forms of cognitive behaviors are examined: perceptions and evaluations. By synthesizing the work of cognitive therapists such as Beck and Ellis, a feedback-loop model of sexual arousal is proposed. It is suggested that cognitive distortions of perception and evaluation operate in most cases of sexual dysfunction. Therefore, a more specific diagnostic schema and a more relevantly planned course of treatment may be designed by pinpointing the troublesome cognitive linkages between sexual stimuli and sexual responses.

This study investigated possible factors in promoting racial integration, a matter of practical concern in schools today. Specifically, the effect of social and tangible reinforcement was studied on the social integration of five black children in a predominantly white classroom. "Sitting and seating with a new friend" in the school cafeteria was manipulated by (a) teacher directive combined with reinforcement and (b) by positive reinforcement alone. Treatment effectiveness was studied in the cafeteria and as generalization effects to a free-play period. The results indicated that reinforcement produced significant generalization to integrated free play, although intersubject variability was present. Evidence suggests that reinforcement techniques can be used effectively to promote social integration.
