The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.

RATIONALE:

Hemoptysis, mild or massive, is worrisome for both patients and physicians. The management is different depending on the causes, which are not well defined for the North American population. Despite the fact that this symptom is commonly reported in clinic, there are only a few studies published on this subject in the North-American population. Tuberculosis was a frequent cause of hemoptysis described in populations overseas, which seems less prevalent in the investigators center.

Also, there are no known official guidelines regarding the investigation and management of hemoptysis. The investigators hypothesized that the use of modern technology in a North American population may result in different findings and provide a more accurate diagnostic approach.

Therefore, the study compares the different etiologies of hemoptysis and investigation modalities used in patients presenting in a North-American tertiary center.

METHOD:

The investigators did a retrospective analysis of medical chart from patients with hemoptysis who visited the investigators center between 2005 and 2010. Each visit has been reviewed individually to describe the characteristics of patients, etiologies of hemoptysis and investigation modalities used. All-cause mortality at 2 years was also recorded.

Descriptive statistical analyses will conducted on the data available.

Etiologies, Investigations and Outcomes of Patients Presenting With Hemoptysis in a North-American Tertiary Center at the Beginning of the 21st Century

Defining the prevalence of pulmonary diseases by measuring the percentage of patients presenting with hemoptysis caused by lung cancer, bronchiectasis, pulmonary embolism, arteriovenous fistula, pneumonia, bronchitis, tuberculosis, mycosis, heart failure, pseudohemoptysis, cryptogenic and other causes.

Determining the sensitivity in obtaining the etiology of the hemoptysis episode of each diagnostic modality that follows : chest X-ray, chest CT-scan and CT-angiography, bronchoscopy, ventilation-perfusion with single-photon emission computed tomography and pulmonary angiography in the diagnosis of different etiologies of hemoptysis.

All-cause mortality at 2 years after the diagnosis of hemoptysis.

Determining the percentage of patients who : never smoked, is an active smoker, former smoker or unknown status.

Determining the average age of the enrolled patients.

Determining the percentage of each gender of the enrolled patients.

Determining the median of the international normalized ratio (INR).

Determining the median of the partial thromboplastin time (PTT).

Determining the average of the platelet count measured per microliter of blood.

Respiratory endoscopy

Devanand Anantham, MRCP

Background: Respiratory endoscopy comprises flexible bronchoscopy and medical thoracoscopy. The diagnostic yield, technical factors and complications for all patient sub-populations is still not clearly defined. This may result in inappropriate or even dangerous application of such procedures. The aim of the study is to collect data on these aspects of respiratory endoscopy and identify important trends, as well as, areas for improvement. This data will also provide baseline comparative data for new bronchoscopic techniques such as endobronchial ultrasound and navigational bronchoscopy.

Method: Prospective data collection. Technical details regarding these procedures are currently keyed into the OTM system by the endoscopy operators for documentation and billing. The department of Respiratory and Critical Care Medicine gets monthly downloads of all the fields from the OTM system for audit purposes.(See data collection form) The research project proposes to make the data non identifiable by removing the patient's name and IC number. Additionally the yield of the procedure will be checked by a chart review of the histology and microbiology results. There are no restrictions on patient recruitment because all procedures will be performed for clinical indications only and no patient will be recruited for the sole purpose of the study. Waiver of consent has been approved by the IRB.

Waiver of consent has been obtained by the IRB. The current estimated bronchoscopy load is 1000/year and data will be kept in the trial co-coordinator's computer in a locked office. The investigators hope to run the database for 3 years initially.

The purpose of this study is to assess the duration of the viral shedding in hematology and oncology patients after a respiratory tract viral infection. This duration has not been much studied in that population whereas it is probably longer than that in immunocompetent patients. Thereby it may be a source of transmission amongst these immunocompromised patients.

The development of multiplex polymerase chain reaction (PCR) tests has greatly improved the diagnosis of respiratory tract viral infections by increasing its sensitivity and the diversity of viral species detected. However, there are few data concerning respiratory tract viral infections amongst hematology and oncology patients. Especially, the duration of viral shedding following an infection has not been much studied whereas it is a source of inter-individual transmission between immunocompromised patients who are more likely to develop severe disease.

Studies conducted so far concerned mainly hematology patients. They have shown that viral carriage could last up to one month and a half in some patients with hematological malignancy.

The aim of this study is to determine the duration of the viral shedding in patients from hematology and oncology units after a respiratory tract viral infection for the ten main viruses involved in order to better manage these infections and to better prevent their transmission.
