Heimlich

The Heimlich maneuver is a lifesaving bystander intervention to assist an individual with airway obstruction however, cholesterol embolization syndrome is a rare, but serious potential complication of the Heimlich maneuver. We present the case of the 56-year-old female presenting to the emergency department with acute right foot pain following performance of the Heimlich maneuver who was found to have distal arterial occlusion resulting from cholesterol embolization syndrome. The patient underwent right popliteal artery exploration, right popliteal and tibial thrombectomy, and popliteal patch angioplasty resulting in restoration of blood flow to her right foot...

BACKGROUND: This study aims to evaluate the effectiveness of pleurodesis procedure by ensuring the expansion of the lung and occluding lung parenchyma leaks with an autologous blood patch. METHODS: A total of 24 patients (17 males, 7 females; mean age 59.9±12.2 years; range, 30 to 86 years) who underwent autologous blood patch pleurodesis in our clinic between November 2015 and November 2019 were retrospectively analyzed. The patients were not eligible to undergo chemical pleurodesis due to a nonexpandable lung or poor general condition...

BACKGROUND: Enhanced recovery after surgery (ERAS) is an evidence-based, multidisciplinary perioperative care model shown to reduce complications and hospital length of stay (LOS). While some thoracic ERAS studies were inconclusive, others demonstrated that ERAS improves patient outcomes after lung resections and provides more cost-effective care. We aimed to investigate the effects of preliminary implementation of an ERAS protocol, in comparison with conventional care, on lung resection outcomes at a single academic institution...

(1) Background: Foreign body aspiration (FBA) is a significant public health concern among the pediatric population, and fatalities are dramatic for families. It typically involves organic foreign bodies (mainly food) aspirated by children under three years old, usually at home or school. This review aimed to focus on the preventive measures around four actual cases of fatal foreign body aspiration, emphasizing the correct execution of the Heimlich maneuver and cardiopulmonary resuscitation, supervised mealtimes, and high-risk foods...

IMPORTANCE: While numerous techniques for costal cartilage harvesting have been described, one consistency in the published literature is that the procedure is performed under general anesthesia. This is the first report to offer IV sedation as a safe alternative to general inhalational anesthesia in cases involving costal cartilage harvesting. OBJECTIVE: To determine the feasibility and safety of costal cartilage harvest with IV sedation. DESIGN: A retrospective chart review was performed of 116 rhinoplasty patients who underwent harvest of costal cartilage grafts under IV sedation from 2005 to 2019...

STUDY OBJECTIVE: The best initial strategy for nontension symptomatic spontaneous pneumothorax is unclear. We performed a systematic review and meta-analysis to identify the most efficacious, safe, and efficient initial intervention in adults with nontension spontaneous pneumothorax. METHODS: MEDLINE, Scopus, Web of Science, and ClinicalTrials.gov were searched from January 1950 through December 2019 (print and electronic publications). Randomized controlled trials evaluating needle aspiration, narrow-bore chest tube (<14 F) with or without Heimlich valve insertion, and large-bore chest tube (≥14 F) insertion in spontaneous pneumothorax were included...

Nontypeable Haemophilus influenzae (NTHI) is a human-restricted pathogen with an essential requirement for heme-iron acquisition. We previously demonstrated that microevolution of NTHI promotes stationary phase survival in response to transient heme-iron restriction. In this study, we examine the metabolic contributions to biofilm formation using this evolved NTHI strain, RM33. Quantitative analyses identified 29 proteins, 55 transcripts, and 31 metabolites that significantly changed within in vitro biofilms formed by RM33...

Cells depend on a highly ordered organization of their content and they must develop strategies to maintain the anisotropic distribution of organelles during periods of nutrient shortage. One of these strategies is to solidify the cytoplasm, which was observed in bacteria, and in yeast cells with acutely interrupted energy production. Here, we describe a different type of cytoplasm solidification that fission yeast cells switch to, after having run out of nutrients during multiple days of culturing. It provides the most profound reversible cytoplasmic solidification of yeast cells described to date...

Placement of a chest tube drains intrapleural fluid and air. The tube should be attached to a drainage system, such as one-, two-, or three-compartment devices, a one-way (Heimlich) valve for ambulatory drainage, a digital system, or a vacuum bottle. The frequently employed three-compartment systems, currently integrated disposable units, allow adjustment of negative pressure or no suction (water seal), and include an air leak meter on the water seal chamber to be used for demonstrating and quantifying air leak...

Background: Studies report a wide spectrum of 124 I positron emission tomography (PET)/computed tomography (CT) sensitivity and specificity in the detection of differentiated thyroid cancer (DTC) lesions. This study reviews the lesion detection rate of pretherapy 124 I PET/CT in different patient populations and further analyzes the factors necessary for a better detection on 124 I PET/CT. Methods: A literature search was performed using multiple different databases (MEDLINE, EMBASE, Northern Lights, and handsearching) covering 1996 to April 2018...

INTRODUCTION: Sickle cell disease (SCD) is among the most common inherited hematologic diseases in sub-Saharan Africa (SSA). Historically, hydroxyurea administration in SSA has been restricted due to limited region-specific evidence for safety and efficacy. METHODS: We conducted a prospective observational cohort study of pediatric patients with SCD in Malawi. From January 2015 to November 2017, hydroxyurea at doses of 10-20 mg/kg/day was administered to children with clinically severe disease (targeted use policy)...

Catamenial pneumothorax is a spontaneous pneumothorax that occurs predominantly women of child bearing age. We describe a case of a 40-year-old nulliparous woman with medical history significant for endometriosis who presented with severe chest tightness of one-day duration. Chest radiography (CXR) showed a large right spontaneous pneumothorax, what was thought to be a 5.6 cm pleural mass at the right lung base. Following pneumothorax diagnosis, the patient underwent emergent right thoracostomy with pigtail catheter placement...

To improve the popularization of the knowledge of the first responders and promote the establishment of the awareness of the first aid, First Aid Professional Committee of Chinese Aging Well Association formulated the Expert consensus on the first responder of the first aid. This consensus aims at the critical and weak link of emergency medical service system (EMSS) in China, providing the public with the first responders action guidance, and guiding the public how to effectively rescue the "first scene", "first time" and "first responder" in the event of sudden injury or illness...

BACKGROUND: Pneumothorax occurs more frequently in the neonatal period than at any other time of life and is associated with increased mortality and morbidity. It can be treated with either aspiration with a syringe (using a needle or an angiocatheter) or a chest tube inserted in the anterior pleural space and then connected to a Heimlich valve or an underwater seal with continuous suction. OBJECTIVES: To compare the efficacy and safety of needle aspiration (either with immediate removal of the needle or with the needle left in situ) to intercostal tube drainage in the management of neonatal pneumothorax (PTX)...

Using correlative light and electron microscopy (CLEM), we studied the intracellular organization by of glucose-starved fission yeast cells ( Schizosaccharomyces pombe ) with regards to the localization of septin proteins throughout the cytoplasm. Thereby, we found that for cells carrying a deletion of the gene encoding septin-2 (spn2Δ), starvation causes a GFP-tagged version of septin-3 (spn3-GFP) and family members, to assemble into a single, prominent filamentous structure. It was previously shown that during exponential growth, spn2Δ cells form septin-3 polymers...

Bacterial pathogens must sense, respond and adapt to a myriad of dynamic microenvironmental stressors to survive. Adaptation is key for colonization and long-term ability to endure fluctuations in nutrient availability and inflammatory processes. We hypothesize that strains adapted to survive nutrient deprivation are more adept for colonization and establishment of chronic infection. In this study, we detected microevolution in response to transient nutrient limitation through mutation of icc. The mutation results in decreased 3',5'-cyclic adenosine monophosphate phosphodiesterase activity in nontypeable Haemophilus influenzae (NTHI)...

Nutrient limitation restricts bacterial growth in privileged sites such as the middle ear. Transient heme-iron restriction of nontypeable Haemophilus influenzae (NTHI), the major causative agent of chronic and recurrent otitis media (OM), promotes new and diverse phenotypes that can influence planktonic, biofilm, and intracellular lifestyles of NTHI. However, the bacterial responses to nutrient restriction that impact intracellular fate and survival of NTHI are unknown. In this work, we provide evidence for the role of transient heme-iron restriction in promoting the formation of intracellular bacterial communities (IBCs) of NTHI both in vitro and in vivo in a preclinical model of OM...
