Brucellosis is a zoonotic disease that remains endemic worldwide. Its clinical manifestations and focal complications are often troublesome in making a diagnosis. Involvement of the respiratory system in brucellosis is an acknowledged but rare event that is only occasionally described in literature. We describe 37 cases of respiratory involvement during the course of brucellosis that presented ...

The novel SARS-CoV-2 virus was thought to affect the respiratory system primarily. During Coronavirus Disease 2019 (COVID-19) pandemic, it became apparent that affected many organ systems, resulting in numerous extra-respiratory manifestations. Though much has been learned about disease during various clinical features still have unclear pathophysiology. Here we outline case of a 49-year-old wi...

Coenzyme Q (CoQ) is an essential electron carrier in the respiratory chain whose deficiency has been implicated in a wide variety of human mitochondrial disease manifestations. Its multi-step biosynthesis involves production of polyisoprenoid diphosphate in a reaction that requires the enzymes be encoded by PDSS1 and PDSS2. Homozygous mutations in either of these genes, in humans, lead to sever...

The relationship between airway hyperreactivity and a history of the clinical manifestations of asthma was investigated in 54 children between the ages of 8 and 12. Airway reactivity was assessed by measuring the change in pulmonary function following the hyperventilation of subfreezing air. Clinical manifestations of asthma were assessed by a standardized questionnaire regarding lower respirat...

Sjögren's syndrome is one of the most common systemic rheumatic diseases. Pulmonary disease is prevalent in Sjögren's syndrome; respiratory manifestations include chronic cough, obstructive airways disease, pulmonary lymphoma, and interstitial lung disease that may progress to severe pulmonary fibrosis.

BACKGROUND Acute respiratory infection (ARI) is a leading cause of morbidity and mortality in children worldwide. This study aimed to determine the viral and atypical bacterial causes of different severities and clinical manifestations of ARI in preschool children from low-income families in North-East Brazil. METHODS Clinical/demographic data and nasopharyngeal aspirates (NPA) were prospecti...

OBJECTIVE To provide a clue for screening severe acute respiratory syndrome (SARS), a highly transmissible disease with health care workers at particular risk, in the early stage from an otolaryngological perspective. DESIGN Prospective study. SETTING Community hospital. PATIENTS Between April 17 and April 26, 2003, 32 consecutive patients with SARS were encountered. Investigation consist...

OBJECTIVES Isolated complex IV (cytochrome c oxidase) deficiency is one of the most frequent respiratory chain defects in mitochondrial disorders (MIDs) and usually occurs together with severe pediatric or rarely adult multisystem disease. Here we report an adult with isolated complex IV deficiency with unusually mild clinical manifestations. CASE REPORT A 50-year-old man had developed genera...

The activated phosphoinositide 3-kinase δ syndrome (APDS), also known as p110δ-activating mutation causing senescent T cells, lymphadenopathy, and immunodeficiency (PASLI), is a combined immunodeficiency syndrome caused by gain-of-function mutations in the phosphoinositide 3-kinase (PI3K) genes PIK3CD (encoding p110δ: APDS1 or PASLI-CD) and PIK3R1 (encoding p85α: APDS2 or PASLI-R1). While the d...

BACKGROUND Fibromyalgia syndrome (FMS) is associated with a variety of symptoms, such as fatigue and dyspnea, which may be related to changes in the respiratory system. The objective of this work was to evaluate pulmonary function, respiratory muscle strength, and thoracoabdominal mobility in women with FMS and its association with clinical manifestations. METHODS The study included 23 women ...
