Hemoptysis is the expectoration of blood from the lung parenchyma or airways. The initial step in the evaluation is determining the origin of bleeding. Pseudohemoptysis is identified through the history and physical examination. In adults, acute respiratory tract infections (e.g., bronchitis, pneumonia), bronchiectasis, asthma, chronic obstructive pulmonary disease, and malignancy are the most common causes. Tuberculosis is a major cause of hemoptysis in endemic regions of the world. Although tuberculosis rates are low in the United States, they are increased in persons who are homeless or who were born in other countries; consideration for testing should be made on an individual basis. Hemodynamic instability, abnormal gas exchange, cardiopulmonary comorbidities, and lesions at high risk of massive bleeding warrant inpatient evaluation. Chest radiography is recommended as the initial diagnostic test for hemodynamically stable patients with hemoptysis. Further evaluation with computed tomography with or without bronchoscopy is recommended in patients with massive hemoptysis, those with abnormal radiographic findings, and those with risk factors for malignancy despite normal radiographic findings.

Chronic pulmonary aspergillosis (CPA) is a refractory disorder that needs long-term antifungal treatment and occasionally results in fatal respiratory failure and hemoptysis. However, the pathological features of the disorder have not been thoroughly delineated. Thirty cases were therefore analyzed clinically and histologically to elucidate the pathophysiology of CPA. The subjects comprised 14 individuals who underwent surgical removal and 16 patients who died. No subject exhibited a severely immunocompromised state. The main symptoms included cough, hemosputum, and dyspnea. Chest computed tomography (CT) findings revealed a cavity, fungus ball, and consolidation and/or ground glass opacity (GGO); 27 serial CT scans showed enlarged consolidation and/or GGO (70%), dilatation of the cavity (26%), and extension to the opposite lung (22%). Histopathological findings revealed a cavity with ulceration, bronchitis, and various degrees of organizing pneumonia (OP) that were correlated with the area of consolidation and GGO on the CT scan. The essential pathophysiology of CPA can be understood as an active state of ulceration of the cavity and/or erosive bronchitis caused by contact with the fungus ball, which may play a significant role in the development of OP. Consequently, OP is thought to reflect respiratory failure that relates to the prognosis of CPA.

Vernonanthura polyanthes (Spreng.) A.J. Vega & Dematt. (Asteraceae), known as "assa-peixe", has been used in ethnomedicine for the treatment of various diseases such as bronchitis, pneumonia, hemoptysis, persistent cough, internal abscesses, gastric and kidney stone pain. Moreover, some studies demonstrated that species of Genus Vernonia present antifungal activity. Due to the biological relevance of this species, the aim of this study was to investigate the toxic, genotoxic, antigenotoxic and antifungal potential of V. polyanthes leaves aqueous extract in somatic cells of Drosophila melanogaster or against Candida spp. The aqueous extract of the plant showed no toxic, genotoxic and antigenotoxic activity in the experimental conditions tested using the wing somatic mutation and recombination test (SMART/wing). However, when the extract was associated with doxorubicin, used in this work as a positive control, the mutagenic potential of doxorubicin was enhanced, increasing the number of mutations in D. melanogaster somatic cells. In the other hand, no inhibitory activity against Candida spp. was observed for V. polyanthes leaves aqueous extract using agar-well diffusion assay. More studies are necessary to reveal the components present in the V. polyanthes leaves aqueous extract that could contribute to potentiate the doxorubicin genotoxicity.

Ochroconis gallopava is an anamorphic mould characterized by slow growth rate and production of a maroon pigment, which has been isolated worldwide from soil, thermal springs, decaying vegetation, and chicken litter. It has been reported to cause localized, mostly pulmonary, and systemic infection in severely immunocompromised patients. We describe the case of a 76-year-old woman known for ulcerative colitis-related bronchiectasis treated with low dose oral steroids, who developed a fungal bronchitis with dark, bloody-like, sputum which was initially misinterpreted as haemoptysis. A filamentary mould grew on sputum culture, and was identified by DNA analysis as Ochroconis gallopava. We observed a significant clinical improvement after 6 weeks of itraconazole therapy.

A 19 year female, presented with life threatening haemoptysis and cough with minimum expectoration for 3 months. Bronchoscopy showed multiple nodules in airway. The direct microscopy and culture of sputum revealed fungal elements and Aspergillus flavus respectively. Serum Galactomannan was positive. Thus diagnosis of invasive aspergillus tracheo-bronchitis made. She responded to voriconazole. Aspergillus tracheo-bronchitis is a rare form of invasive pulmonary aspergillosis in immuno-competent host. Aspergillus spp in respiratory samples should not be routinely discarded as colonization.

A 39-year-old gentleman presented to emergency department with a few hours' history of acute shortness of breath, cough and haemoptysis that developed whilst welding a steel tank in a closed container. He was welder by profession for thirteen years with no significant past medical history. The arterial blood gas showed severe oxygenation impairment and he was intubated for mechanical ventilation. The radiographs showed bilateral widespread interstitial shadowing. The echocardiography showed normal heart and ruled out cardiogenic pulmonary oedemic. The microbiological investigations were all normal. He was treated as Acute Respiratory Distress Syndrome (ARDS) secondary to exposure to welding metal fumes in a closed container. He was given limited tidal volume invasive ventilation, extubated successfully after twelve days, transferred to respiratory ward for rehabilitation and discharged few days later. Exposure to welding metal fumes at work place is a major occupational health hazard worldwide. It can cause ARDS and other respiratory illnesses such as bronchitis, metal fumes fever and chronic pneumonitis. The pathogenesis of ARDS due to welding metal fumes involves direct inhalational injury and/or immune system dysfunction. Welding metal fumes related ARDS remains the diagnosis of exclusion and all other causes must be ruled out. The key to treatment is ventilation support with early endotracheal intubation. Appropriate precautionary measures are advised to avoid occupational health hazards in welding profession.

Hemoptysis is defined as bleeding from the lower respiratory tract. It can be life-threatening and requires urgent investigation and intervention. Common causes of hemoptysis include bronchiectasis, tuberculosis, aspergilomas and malignancy. We present an unusual case of hemoptysis in a young woman with a history of surgery for scoliosis 18 years earlier. A 30-years-old woman was admitted to our institution for recurring hemoptysis since one year. She had a history of scoliosis and had undergone antero-lateral Th7 through Th12 spinal fusion surgery 18 years earlier. The hemoptysis was slight and resolved spontaneously or after empirical antibiotic therapy, and was attributed to bronchitis. Computed tomography revealed spinal rod penetration into the lung resulting in injury, while the caudal edge of the rod migrated into the liver and the joining screws had entered the mediastinum. Hemoptysis was due to penetration of the rod into the lung. The patient underwent extensive surgery, which was successful. The case highlights the need for thorough evaluation of patients with hemoptysis. Every incident of hemoptysis, even if minor, should be promptly investigated, because it can be life-threatening.
