Factors influencing sensitivity of a rapid influenza diagnostic test in a community-based population of kindergarten through 12th-grade students: Wisconsin 2015-2020.

Rapid influenza diagnostic tests (RIDTs) have variable sensitivity. In a community-based population of kindergarten through 12th-grade (K-12 … p < 0.001), nasal congestion (1.59, p = 0.045), days from symptom onset (per day; 0.75; p < 0.001), myalgia (0.61; p = 0.014), age (per 5 years; 0.55; p = 0.001), and detection of another virus (0.50; p = 0.043). Understanding these factors can aid in interpreting negative results.

Viral neuromyopathy associated with acute hepatitis B infection.

Viral myositis is commonly seen with influenza and COVID-19 infections. While it has been described with acute viral hepatitis, concomitant involvement of the peripheral nerves causing a neuromyopathy has not been reported. A 67-year-old man with acute hepatitis B infection developed a severe myalgia and lower limb weakness around 1 month into his illness. Investigations revealed a neuromyopathy and rhabdomyolysis. MRI whole body with short tau inversion recovery sequences showed scattered muscle hyperintensities in the upper and lower limbs. He was treated with intravenous immunoglobulin and …

A rare presentation of scrub typhus: myocarditis, acute liver failure and leukemoid reaction.

Scrub typhus is a mite borne zoonosis, caused by Orientia tsutsugamushi, a gram-negative intracellular organism. This infection usually presents in high prevalence in the rural areas of East Asia and Western pacific islands. It usually presents with fever, chill, myalgia, headache, skin rashes, having pathognomonic and skin lesion i.e. eschar in ~10% cases in Indian subcontinent. It can present with life-threatening complications on occasional. The simultaneous presentation of more than two complications is uncommon, rarely reported in literature. Here we report a case of 37-year-old woman wit…

Infective Endocarditis With Secondary Headache: A Case Report.

Secondary headache is a symptom of an underlying disease. Infective endocarditis (IE) is a serious infection of the heart tissue. Herein, we present a rare case of IE, with a secondary headache. The patient presented with persistent headache, fever of 39°C, myalgia, and painful erythema of the plantar surface of the foot. The headache progressively worsened over a few weeks. She was diagnosed with secondary headache, and sepsis was suspected. Blood culture revealed the presence of Streptococcus viridans, leading to a diagnosis of IE. Postoperatively, the patient recuperated without any complic…

[Emergency pulmonary lobectomy in a patient with severe hemoptisis due to COVID-19].

The most common symptoms in patients with SARS-CoV-2 infection are fever, cough, odynophagia, headache, myalgia, and diarrhea. A much smaller percentage have dizziness, rhinorrhea, and hemoptysis as associated symptoms. However, the great magnitude that this second wave acquired, can make this last complication appear more frequently. This report describes the case of a 49-year-old patient with a history of recent COVID-19 infection with requirement of mechanical ventilation due to respiratory failure, who developed during hospitalization in the general ward with parapneumonic pleural effusion…

Musculoskeletal involvement of COVID-19: review of imaging.

The global pandemic of coronavirus disease 2019 (COVID-19) has revealed a surprising number of extra-pulmonary manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. While myalgia is a common clinical feature of COVID-19, other musculoskeletal manifestations of COVID-19 were infrequently described early during the pandemic. There have been emerging reports, however, of an array of neuromuscular and rheumatologic complications related to COVID-19 infection and disease course including myositis, neuropathy, arthropathy, and soft tissue abnormalities. Multimodal…

COVID-19 and Gastrointestinal Symptoms-A Case Report.

COVID-19, a new illness secondary to a novel Coronavirus emerged in December 2019 in China. Our early understanding of the clinical features of COVID-19 has been based on case series emerging from the first outbreak in Wuhan. These features included fever, a dry cough, myalgia and dyspnea. Gastrointestinal symptoms were rarely reported as a key feature. We present a case report of a 74-year-old male who presented with symptoms of gastroenteritis and subsequently tested positive for COVID-19. This article aims to highlight an uncommon presentation of COVID-19 and that a high index of suspicion …

Uncommon presentation of COVID-19: Gastrointestinal bleeding.

The COVID-19 outbreak has become a pandemic that is threatening global health. The typical clinical manifestations were fever, cough, dyspnea, and myalgia or fatigue. Digestive symptoms such as nausea, vomiting, diarrhea, abdominal pain usually accompany respiratory symptoms. However gastrointestinal bleeding as the first symptom is not reported. Here we reported a case of COVID-19 with gastrointestinal bleeding as the initial symptom to the emergency department with a real-time reverse transcriptase polymerase chain reaction test positive, and normal thorax tomography. The case demonstrate th…

COVID-19 Associated Pneumonia and Pleural Effusion Masquerading as Heart Failure in Rheumatic Heart Disease.

UNLABELLED: The ongoing outbreak of coronavirus disease 2019 (COVID-19) that began in Wuhan, China, became an international emergency when thousands of people were infected around the world. COVID-19 emerged in Pakistan in April 2020, precipitating a nationwide lockdown. While some countries are now recovering from the pandemic, its peak is not estimated to occur in Pakistan until August 2020. We present a case of rheumatic heart disease with fever, myalgia and an unusual radiological finding of the virus. LEARNING POINTS: Unusual radiological findings are being seen in COVID-19 patients.Pleu…

Microscopic polyangiitis: an incidental finding in a patient with stroke.

Microscopic polyangiitis (MPA) is a primary systemic vasculitis characterized by inflammation of small-sized vessels associated with the presence of anti-neutrophilic cytoplasmic antibodies. We report a case of a 39-year-old female diagnosed with microscopic polyangiitis as an incidental finding who presented with signs and symptoms of a stroke at a young age. Usually, it presents with fever, malaise, skin rash, weight loss, mononeuritis multiplex, and arthralgia/myalgia. Very rarely, it can involve meninges to cause meningeal vasculitis which can present as a febrile seizure. The most frequen…

Unique Presentation of an Inflammatory Abdominal Aortic Aneurysm With Rhabdomyolysis.

OBJECTIVE: This study reports the case of a 72 year old male who presented with rhabdomyolysis and a symptomatic juxtarenal inflammatory abdominal aortic aneurysm (IAAA). He underwent open repair of his IAAA with a polytetrafluoroethylene graft using the transperitoneal approach. RESULTS: The patient's aneurysm had significant inflammation with a thick rind of friable tissue overlying the native aorta. He had no history of autoimmune disease to serve as a potential trigger of his symptomatic IAAA. Prior to his presentation, however, he did experience three months of myalgia, with a concomitan…

How to do it: investigate exertional rhabdomyolysis (or not).

Rhabdomyolysis is the combination of symptoms (myalgia, weakness and muscle swelling) and a substantial rise in serum creatine kinase (CK) >50 000 IU/L; there are many causes, but here we specifically address exertional rhabdomyolysis. The consequences of this condition can be severe, including acute kidney injury and requirement for higher level care with organ support. Most patients have 'physiological' exertional rhabdomyolysis with no underlying disease; they do not need investigation and should be advised to return to normal activities in a graded fashion. Rarely, exertional rhabdomyolysi…

Hydralazine-associated antineutrophil cytoplasmic antibody vasculitis with pulmonary-renal syndrome.

Hydralazine, a vasodilator, is commonly used as an adjunctive treatment for moderate to severe hypertension, heart failure and hypertensive emergencies in pregnancy. Hydralazine-induced lupus was first described in 1953. Clinical presentation ranges from arthralgia, myalgia, petechiae, or rash to single or multiorgan involvement. An occurrence of systemic vasculitis is a rare complication. When presented as the pulmonary-renal syndrome, it could have a rapidly progressive course which can be fatal. Here, we describe a case of hydralazine-associated rapidly progressive glomerulonephritis and pu…

Chikungunya virus: epidemiology, replication, disease mechanisms, and prospective intervention strategies.

Chikungunya virus (CHIKV), a reemerging arbovirus, causes a crippling musculoskeletal inflammatory disease in humans characterized by fever, polyarthralgia, myalgia, rash, and headache. CHIKV is transmitted by Aedes species of mosquitoes and is capable of an epidemic, urban transmission cycle with high rates of infection. Since 2004, CHIKV has spread to new areas, causing disease on a global scale, and the potential for CHIKV epidemics remains high. Although CHIKV has caused millions of cases of disease and significant economic burden in affected areas, no licensed vaccines or antiviral therap…

Toxic Epidermal Necrolysis and Sepsis.

UNLABELLED: A 63-year-old male patient suffered from myalgia, arthralgia cough and erythematous macules, with confluence to the thorax, limbs, thighs and the scrotum. The erythematous macules evolved to blisters with a positive Nikolsky's sign. A cutaneous biopsy revealed satellite cell necrosis. Administration of immunoglobulins resulted in a favourable evolution of the cutaneous lesions. Toxic epidermal necrolysis (TEN) is a rare and potentially fatal mucocutaneous disease. Early recognition, diagnosis and therapy are of the utmost importance. LEARNING POINTS: Toxic epidermal necrolysis (TE…

Hypokalemia and rhabdomyolysis.

The adverse drug event manager of the Capital Region of Denmark received a report of a 65-year-old male with type II diabetes and long-lasting treatment with indapamide. In addition, he had a history of a high consumption of licorice. For 2 weeks, the patient suffered from myalgia, which the general practitioner suspected to be polymyalgia rheumatica and referred him to the hospital. Initial blood samples revealed a reduced potassium concentration of 1.5 mmol/L (reference value: 6.6-4.6 mmol/L) and an elevated creatine kinase of 18,400 IU/L (reference value: 40-280 IU/L). We believe that the p…

Myopathy during treatment with the antianginal drug ranolazine.

Ranolazine is a medication indicated for treatment of chronic angina and is a partial inhibitor of the fatty acid β-oxidation. We present an adult patient who developed subacute progressive muscle weakness and exercise-induced myalgia, soon after increasing the daily dose of ranolazine, in the setting of therapy with simvastatin. CK persisted normal throughout the duration of the weakness and muscle biopsy showed a lipid storage myopathy for which no underlying genetic defect was identified. Discontinuation of both drugs resulted in clinical improvement. Although simvastatin may have contribut…

Trichinosis caused by ingestion of raw soft-shelled turtle meat in Korea.

Reptiles, unlike mammals, have been considered to be unsuitable hosts of Trichinella spp., though larvae have been detected in their muscles and human outbreaks related to their consumption have, in fact, occurred. Herein we report 2 Korean cases of trichinosis, possibly transmitted via consumption of reptile meat. Both patients suffered from myalgia, headache, and facial edema. Laboratory examinations revealed leukocytosis with eosinophilia (54% and 39%, respectively) and elevated creatinine phosphokinase. ELISA was performed under the suspicion of trichinosis, showing positivity at the 29th …
