Intratracheal Nodular Fasciitis: a Rare Lesion Case Report

Nodular fasciitis is a benign proliferation of myofibroblasts that usually arises in subcutaneous tissues of the trunk, neck, head, and upper extremities of young to middle-aged adults. It is not reported to arise in the intratracheal. We present a patient with chest tightness and asthma for three months. Chest computed tomography showed no displayed of left bronchus. The trachea of the left main bronchus was blocked by organisms under bronchoscope. The organisms were extracted and pathologically diagnosed as a rare, benign, intratracheal nodular fasciitis. One month later, the patient relapsed again and underwent resection.

Guidelines for management of hereditary angioedema: What is new? What is missing?

Background: Hereditary angioedema is an autosomal dominant disease that presents with recurrent episodic swelling of the submucosal and/or subcutaneous tissues of the cutaneous, gastrointestinal, and respiratory systems. Evaluation and treatment guidelines have been published nationally and internationally to aid the treating provider. Methods: A review of the most cited and most recent updated guidelines was undertaken to review key points and to explore real-world feasibility of incorporating them into clinical practice. The International World Allergy Organization/European Academy of Allergy and Clinical Immunology (WAO/EAACI) Guideline for the Management of Angioedema - The 2017 Revision and Update, and the consensus reports from the Hereditary Angioedema International Working Group, the Joint Task Force on Practice Parameters focused practice parameter update, and the most recently updated US HAEA Medical Advisory Board 2020 Guidelines for the Management of Hereditary Angioedema were reviewed and summarized. Results: Key points that have been consistent throughout the guidelines include recommendations for evaluation and classification of hereditary angioedema as well as evidence-based guidelines for treatment. Further attention is required on the evaluation and continuous assessment of the burden of illness and quality of life (QoL). Conclusion: The guidelines for management of hereditary angioedema provide a framework for the clinician. However, the physician-patient dialog with regard to the patient disease experience, which includes attack frequency, severity, and Qol, must be continually assessed.

Subcutaneous Facial Emphysema Following Open-Flap Air-Powder Abrasive Debridement for Peri-Implantitis: A Case Report and an Overview

Subcutaneous facial emphysema related to dental treatments is a well-known clinical complication due to incidental or iatrogenic air or gas penetration into the subcutaneous tissues and fascial planes, leading to distension of the overlying skin. To the best of our knowledge, from 1960 to the current date, only six cases have been reported arising from peri-implant cleaning or non-surgical peri-implantitis treatment. Therefore, the present case of subcutaneous facial emphysema following open-flap air-powder abrasive debridement was the first report during surgical peri-implantitis therapy. Swelling on the left cheek and periorbital space suddenly arose in a 65-year-old woman during open-flap debridement with sodium bicarbonate air-powder abrasion (PROPHYflex™ 3 with periotip, KaVo, Biberach, Germany) of the infected implant surface. The etiology, clinical manifestations, diagnosis, potential complications, and management of subcutaneous emphysema are also briefly reviewed. The present case report draws the attention of dental practitioners, periodontists, oral surgeons, and dental hygienists to the potential iatrogenic risk of subcutaneous emphysema in using air-powder devices in implant surface debridement.

High-Definition Liposuction Body Scale: Expanding Indications for High-Definition Liposuction

Introduction: Performing optimal gluteal augmentation using traditional methods in moderate to severe weight-loss patients poses a surgical challenge as such patients typically present with (1) severe skin redundancy, (2) soft tissues containing high-density connective tissues than fat content, and (3) ptotic buttock cheeks. Materials and Methods: This procedure uses a modified lateral thigh and buttock tuck excision not only to lift the buttock cheek complex but also to create a dermal fat flap that is transposed into the upper buttock pole to achieve upper buttock fullness. The remainder of the excised tissue undergoes novel ex vivo liposuction while remaining sterile, which allows for simultaneous repair of the created excision line. Results: This novel ex vivo liposuction technique provides several advantages that include (1) limiting operative time, (2) allowing for maximal fat removal while avoiding unnecessary trauma to the patient, and (3) providing improved quality with less blood and fat volumes. This ex vivo fat is then transferred to the mid- and lower buttock to complete buttock augmentation for the Brazilian buttock lift. Discussion: Excess skin redundancy and buttock check ptosis require consideration of supplemental excisional tucking to achieve optimal results. In addition, subcutaneous tissues that maintain more connective tissue pose difficulty with fat removal using traditional liposuction techniques. As such, we present a novel surgical technique to optimally augment and shape the buttock in patients who have undergone weight loss. Conclusion: In summary, we present a novel Brazilian buttock lift technique to augment the buttock in weight-loss patients that maximizes both patient safety and efficacy.

Ultrasound findings in subcutaneous plantar vein thrombosis: retrospective analysis of seven patients

Background Several disorders may result in forefoot pain. An uncommon cause of forefoot pain is subcutaneous plantar veins thrombosis (SCPVT) involving veins superficial to the plantar fascia. Purpose To describe the ultrasound (US) appearance of SCPVT, which has been described only once in the radiological literature. Material and Methods We performed a retrospective search of our PACS system from 2016 to 2020 to collect all cases of US-diagnosed SCPVT. We collected data on seven patients. Two radiologists analyzed the US images retrieved. All US examinations were performed with a multifrequency linear probe (frequencies in the range of 5–17 MHz). Results A localized plantar nodule was palpable in 86% of patients. The subcutaneous thrombosed vein appeared in all patients as a round or ovoid nodule located in the subcutaneous tissues that corresponded in four patients (4/5, 80%) to the painful palpable nodule. The size was in the range of 4–7 mm (mean = 5.4 mm). The thrombosed vein presented a connection with adjacent patent veins, appeared enlarged, and almost filled with hypo-isoechoic material, and in two patients (2/7, 29%), a thin peripheral fluid component surrounding the thrombus was detectable. Continuous scanning demonstrated slow blood movements inside the peripheral component due to blood circulation. Failure to compress the lumen of the thrombosed vein during the real-time US was evident in all patients. Conclusion SCPVT is a rare or underreported condition. Sonologists must know the US appearance of SCPVT to exclude other conditions and avoid unnecessary invasive studies.

Case Report: Disseminated Cysticercosis due to Intentional Ingestion of Parasitic Worm Eggs for Weight Loss

A 20-year-old female resident of Beijing intended to consume the eggs of the parasitic worm, Taenia saginata, for weight loss; however, she apparently inadvertently ingested Taenia solium (pork tapeworm) eggs, which resulted in disseminated cysticercosis. Cysticerci developed in the brain, tongue, muscles, liver, peritoneum, and subcutaneous tissues. She was administered oral albendazole and praziquantel. After four 10-day courses of treatment, most of the cysts disappeared and she recovered. After 3 years, the patient remains in good health.

Nursing Skill and Responsibility in Administration of Low Molecular Weight Heparin by Prefilled Syringe

Low-molecular-weight heparins (LMWHs) have proven to be effective in the prevention and treatment of thrombotic disorders, as well as substitute for unfractionated heparin (UFH). LMWHs are a diverse collection of medicines with different biochemical and pharmacological characteristics, despite the fact that they all have antithrombotic actions. Medicine is administered into the subcutaneous tissues with these injections. Small amounts of injections are delivered by the subcutaneous approach, which involves inserting a small thin needle beneath the skin and slowly injecting the medicine. Low molecular weight heparins make up dalteparin and enoxaparin, two anticoagulants. The rights of medicine administration must be followed by nurses. For patients on LMWH medication, the most essential blood test is prothrombin time. Following administration, look for any signs of bleeding, such as occult blood in the stool, malena, bleeding gums, and skin discoloration/hematoma. The antidote for low molecular weight heparin is protamine sulphate. It is effective at counteracting the effects of LMWH. 100 units of LMWH are neutralised by 1 mg of protamine sulphate.If it's been more than 8 hours since you've given LMWH, provide 0.5 mg protamin per 100 units of LMWH.

Manufacturing of a Gelatin Phantom with Lymphedema for Ultrasonic Imaging Measurement

For diagnosis of the secondary lymphedema, amplitude mode (A-mode) examination using a single ultrasound probe has been suggested as one of possible diagnostic modalities due to its relatively low cost, ease of usage, and mobility. However, A-mode ultrasound waves with respect to time have lots of noise and are complicated to analyze and achieve well correlated information related to change in volume of each layer of skin and subcutaneous tissues. Thus, development of adequate ultrasound calibration phantom is needed. For this, fundamental study on proper phantom materials which show acoustic characteristics of skin and subcutaneous tissues are needed. In this research, the fabrication method for ultrasonic phantom using gelatin material is presented in a wide range of acoustic impedance and their acoustic characteristics and usability were discussed.

Bilateral Posterior Auricular Masses: A Case of Kimura’s Disease

Kimura’s disease (KD) is currently considered a rare chronic inflammatory disease of unknown etiology. It is more common in the Asian population, especially in young and middle-aged men, and can involve the lymph nodes, salivary glands, and subcutaneous tissues. It has been reported in adults and children, and is often accompanied by elevated peripheral blood eosinophils and elevated serum immunoglobulin E (IgE). Herein, we report a case of KD in a 46-year-old man with bilateral masses behind the ears since childhood that had gradually enlarged over 40 years. The patient’s peripheral blood eosinophils were elevated, and interestingly, homocysteine levels were also elevated. After surgical resection of the bilateral posterior auricular masses, follow-up over 5 years indicated good recovery and no signs of recurrence.
