Testing the Relationship Between Respiratory Diseases and Viral Infections in Various Age Groups / Respiratory Diseases and Viral InfectionsSantarelli, Leanne 12 1900 (has links)
The objective of this project was to investigate and determine the association between hospitalizations of respiratory diseases with one another and with isolations of viral infections in five age groups. Weekly data on all hospitalizations in Ontario, Canada, from week 14 of 2001 to week 13 of 2003 were obtained for 5 age groups (under 2 years, 2 to 4 years, 5 to 15 years, 16 to 49 years and over 50 years inclusive) for respiratory diseases including, asthma, respiratory tract infection (RTI) and chronic obstructive pulmonary disease (COPD)1. Furthermore, data for viral infections including influenza virus type A and type B (Flu AB) and respiratory syncytial virus (RSV) isolations were also obtained from Health Canada for the same weekly time periods. In order to test for independence and determine a relationship, if any, between hospitalizations of respiratory diseases with one another and with isolations of viral infections, structural time series models were developed for all age groups of the respiratory diseases and explanatory variables were modeled accordingly against the hospital admission counts for the respiratory diseases. These explanatory variables include, other respiratory diseases, viral infections, and lagged values of the dependent variable. Neither FLU AB nor RSV showed a significant relationship with asthma patients of all ages. Weekly RSV peaks coincided with RTI patients under 2 years and RTI peaks in patients 5 to 15 years preceded FLU AB peaks. A relationship between all three respiratory diseases, asthma RTI and COPD, was discovered for all age groups. Peaks of asthma coincided with various transformations of RTI peaks for the five age groups and peaks of COPD coincided with both the untransformed asthma and RTI peaks in patients over 50. For all other relationships, the null hypothesis of independence was accepted. These findings suggest that there is a strong association between respiratory diseases and that children and adults with respiratory diseases respond differently to viral infections. 1 Only data for patients over 50 years was obtained for COPD. / Thesis / Master of Science (MSc)

BACKGROUND
Acute gastroenteritis (AGE) is a common problem in both inpatient and outpatient settings. Most cases are viral in origin, with norovirus being the most cited. Typical symptoms include low-grade fever, chills, nausea, vomiting, and abdominal discomfort. The physical examination is usually unremarkable, but abdominal tenderness or signs of volume depletion may be present in severe disease. Most patients have spontaneous remission within a few days and do not require hospitalization or diagnostic evaluation. Laboratory evaluation is often helpful in severe disease, immunocompromised patients, or when bloody or mucoid diarrhea is present. Polymerase chain reaction (PCR) gastrointestinal multiplex testing is often the preferred evaluation as it has a high sensitivity, specificity, and turnaround time when compared to traditional stool studies of enzyme-immunoassay studies. Treatment is often supportive, but specific bacterial and parasitic pathogens should prompt treatment with antimicrobial therapy.
CASE PRESENTATION
This case presents a 47-year-old male with no known previous medical history or history of intraabdominal surgeries. He presented with four days of progressive nausea, vomiting, diarrhea, and abdominal discomfort. The physical examination revealed a distended and tender abdomen. The metabolic panel did not show any electrolyte derangements. Computed tomography with intravenous contrast revealed partial small bowel obstruction versus less likely ileus. Gastrointestinal pathogen PCR returned positive for norovirus. The patient was given intravenous fluid, nausea control, and pain control, his diet was advanced, and his symptoms subsequently resolved.
We believe this case to be unusual, as most cases of viral gastroenteritis are uncomplicated, and this patient presented with radiographic evidence of ileus versus partial small bowel obstruction. PCR testing revealed positivity for norovirus. He had no previous abdominal surgeries or family history of early intestinal malignancies, and the symptoms spontaneously resolved with several days of conservative management, making another etiology much less likely.
CONCLUSION
AGE is a common diagnosis seen in the primary care clinic, and most patients have an uneventful recovery. However, suspicion of partial obstruction or intestinal ileus should arise when severe abdominal pain and prolonged vomiting are present.
