Project description:Highlights•Spindle cell sarcoma is rare and may remain silent until advanced.•Symptoms include obstruction, local invasion, embolism, and sudden cardiac death.•It is a highly aggressive tumor and can metastasize quickly.•Overall prognosis is poor, with a mean survival of 3 months to 1 year.•Several imaging modalities are used, including echocardiography, CT, and cardiac MRI.

Project description:BackgroundOne of the rationales behind using strength training in the treatment of adolescents with Patellofemoral Pain (PFP) is that reduced strength of the lower extremity is a risk factor for PFP and a common deficit. This rationale is based on research conducted on adolescents >15 years of age but has never been investigated among young adolescents with PFP.ObjectivesTo compare isometric muscle strength of the lower extremity among adolescents with PFP compared to age- and gender-matched pain-free adolescents.MethodsIn 2011 a population-based cohort (APA2011-cohort) consisting of 768 adolescents aged 12-15 years from 8 local schools was formed. In September 2012, all adolescents who reported knee pain in September 2011 were offered a clinical examination if they still had knee pain. From these, 20 adolescents (16 females) were diagnosed with PFP. Pain-free adolescents from the APA2011-cohort (n?=?20) were recruited on random basis as age- and gender-matched pairs. Primary outcome was isometric knee extension strength normalized to body weight (%BW) and blinded towards subject information. Secondary outcomes included knee flexion, hip abduction/adduction and hip internal/external rotation strength. Demographic data included Knee Injury and Osteoarthritis Outcome Score (KOOS) and symptom duration.ResultsAdolescents with PFP reported long symptom duration and significantly worse KOOS scores compared to pain-free adolescents. There were no significant differences in isometric knee extension strength (?0.3% BW, p?=?0.97), isometric knee flexion strength (?0.4% BW, p?=?0.84) or different measures of hip strength (?0.4 to 1.1% BW, p>0.35).ConclusionYoung symptomatic adolescents with PFP between 12 and 16 years of age did not have decreased isometric muscle strength of the knee and hip. These results question the rationale of targeting strength deficits in the treatment of adolescents with PFP. However, strength training may still be an effective treatment for those individuals with PFP suffering from strength deficits.

Project description:A 26-year-old smoker male presented with a history of sudden onset dyspnea and right-sided chest pain. Chest radiograph revealed large right-sided pneumothorax which was managed with tube thoracostomy. High-resolution computed tomography thorax revealed multiple lung cysts, and for a definite diagnosis, a video-assisted thoracoscopic surgery-guided lung biopsy was performed followed by pleurodesis. This clinicopathologic conference discusses the clinical and radiological differential diagnoses, utility of lung biopsy, and management options for patients with such a clinical presentation.

Project description:Clinical History:A 57-year old woman presented with left hand pain, periodic leg movement during sleep, gradual onset of stiffness, clumsiness, and falls. Neurological examination showed: generalized rigidity and bradykinesia. There was left hand dystonic posturing and ideomotor apraxia, as well as mirror movements of upper limbs and stimulus-sensitive myoclonus. The patient had a high-pitched voice and hypophonia (Video S1). Discussion:Experts discuss localization and the syndromic diagnosis and predict the underlying pathology. The pathological diagnosis is then provided and clinical learning points are considered.

Project description:Pericarditis is a rare, but severe cause of chest pain in children that can easily be overlooked during routine diagnostics. Fibrinous pericarditis was recognized in a 5-year old patient who presented with fever and chest pain. Despite thorough diagnostics, no evident etiological factor was found. Furthermore, the disease was unresponsive to broad-spectrum antibiotics and NSAIDs, however oral prednisone was found to cause rapid improvement in the patients' condition. It was presumed that the patient's condition was caused by a blunt trauma to the chest experienced 3 days prior to the onset of symptoms. In an 8-month follow-up the patient remains in good overall condition and no recurrences were observed.

Project description:Left ventricular noncompaction (LVNC) is a distinct cardiomyopathy that is morphologically characterized by a two-layered myocardium, numerous prominent trabeculations, and deep intertrabecular recesses communicating with the left ventricular cavity. We present a case report regarding the identification of a new mutation in TNNI3 in a patient with LVNC using next-generation sequencing. A 13-year-old girl who had no family history of cardiac disease was hospitalized with dyspnea after exercise and electrocardiographic abnormalities during a school screening. Based on her clinical features, she was diagnosed with LVNC. Via genetic analysis, a TNNI3 heterozygous missense variant was identified in the proband. Although mutations in TNNI3 have been reported in patients with hypertrophic cardiomyopathy and restrictive cardiomyopathy, this is the first report of a mutation in this gene in a patient with LVNC. <Learning objective: We identified a variant in TNNI3 in a patient with isolated left ventricular noncompaction using next-generation sequencing (NGS). Mutations in TNNI3 have been reported in patients with hypertrophic cardiomyopathy and restrictive cardiomyopathy. The use of NGS also results in the identification of multiple genetic variants of unknown significance to the investigated disease.>.

Project description:Isolated ventricular noncompaction, a rare genetic cardiomyopathy, is thought to be caused by the arrest of normal myocardial morphogenesis. It is characterized by prominent, excessive trabeculation in a ventricular wall segment and deep intertrabecular recesses perfused from the ventricular cavity. The condition can present with heart failure, systematic embolic events, and ventricular arrhythmias. Two-dimensional echocardiography is the typical diagnostic method. We report a case of heart failure in a 35-year-old man who presented with palpitations. Two-dimensional echocardiograms revealed left ventricular noncompaction, which markedly improved after standard heart failure therapy.

Project description:ObjectivesTo identify the gram-negative rods grown from blood cultures and a right-knee fluid aspirate from an 80-year-old caucasian man who had undergone a total right knee arthroplastic procedure 6 years ago, and to assess the genetic similarity between the 2 isolates.MethodsWe used 3 different approaches: biochemical testing, matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry, and 16S ribosomal RNA (rRNA) gene sequencing.ResultsThe 3 methods identified the gram-negative rods as Pasteurella multocida; 16S rRNA gene sequencing further identified the organisms as P. multocida subsp. septica.ConclusionA concordant identification of P. multocida was observed using biochemical testing, mass spectrometry, and 16S rRNA gene sequencing. Only 16S rRNA sequencing was able to determine the subspecies of P. multocida and to determine the genetic relatedness of the 2 isolates.

Project description:Case presentationA 56-year-old man presented to the lung nodule clinic with abnormal chest imaging prompted by a chronic cough and hemoptysis. Approximately 2.5 years earlier, while kneeling beside his car fixing a flat tire, he fell backwards while holding the tire cap in his mouth, causing him to inhale sharply and aspirate the cap. He immediately developed an intractable cough productive of flecks of blood. He presented to an emergency room but left before being seen because of a long wait time and his lack of health-care insurance. He self-medicated for severe cough and chest discomfort with codeine, eventually developing a dependency. Approximately 3 weeks after aspirating the tire cap, his cough became productive, and he developed fever and chills. His symptoms improved transiently with antibiotics and additional narcotics. Ultimately, his chronic cough with intermittent hemoptysis affected his ability to work, and 30 months later he sought medical attention and was diagnosed with pneumonia and reactive airway disease. He was prescribed doxycycline, steroids, inhaled albuterol, and dextromethorphan, with initial improvement, but his symptoms recurred multiple times despite quitting smoking, leading to repeated medication courses.
