This study shows the beneficial effects of ketogenic diet in obese diabetic subjects following its long-term administration. Furthermore, it demonstrates that in addition to its therapeutic value, low carbohydrate diet is safe to use for a longer period of time in obese diabetic subjects.

Background: Multiple animal antigens, spores and pollens were collected and identified from the Kuwaiti atmosphere. The role for these antigens in mediating allergic rhinitis for Kuwaiti residents needs to be evaluated. Objective: To investigate the causes (both indoors and outdoors) of allergic rhinitis for Kuwaiti residents. Method: This is a retrospective study of all positive skin tests that we obtained in our Allergy clinic in Mubarak Alkabeer Hospital in Kuwait, during the period between May 2013 and December 2015, from patients who presented with allergic rhinitis symptoms and/or signs. They underwent skin prick tests to a battery of common allergens (german cockroach, cat dander, dog dander, house dustmites mix, cladosporium, aspergillus mix, penicillium mix, alternaria, grass pollens mix, Russian thistle pollens, mugwort pollens, rough pigweed pollens, sorrel pollens, compositae pollens, olive pollens, and date palm pollens). A wheal of ≥3 mm was considered a positive skin test. Results: A total of 177 patients with rhinitis (90 females and 87 males) had positive test results to at least one allergen and were considered allergic. 77.9% of the patients had positive results to Russian thistle pollens, 39.9% to cat dander, 29.9% to grass pollens mix, 22.6% to compositae pollens, 22.6% to mugwort pollens, 22% to house dust mites mix, 21.4% to olive pollens, 20.9% to German cockroach, 20.3% to dog dander, 18.1% to rough pigweed pollens, 15.8% to date palm pollens, and 12.4% to sorrel pollens, 14.7% to penicillium, 10.7% to cladosporium, 10.7% to aspergillus mix, and 4% to alternaria. Conclusion: Russian Thistle pollen is the commonest sensitization for Kuwaiti residents with allergic rhinitis. Background: Environmental allergies affect many individuals of all ages. There are several aeroallergens that can trigger allergic reactions, namely allergic rhinitis and allergic asthma. In this study, we aimed to determine the prevalence of various environmental allergies in the Kingston, Ontario region. Methods: A chart review of skin prick test (SPT) results was completed on all patients in the practice of an academic Allergist affiliated with Queen's University. Patients who demonstrated positive SPT (defined as ≥3 mm than the negative control) to one or more allergens were included, and their age, gender and specific positive tests were recorded. Allergens evaluated included dust mites (D. pteronyssinus and D. farinae), dog dander, cat epithelium, tree mixes, birch pollen, other trees, grass mixes, ragweed mixes, short ragweed, other weeds, cockroach and numerous moulds. Of all patients reviewed, 1161 had positive SPT results to one or more allergens. Data analysis was completed with SPSS. Results: Dust mite was the most prevalent allergen (62.6%). The second and third most common were ragweed (52.6%) and cats (51.6%), respectively. The prevalence of other allergens, in order of decreasing frequency, were grass (49.7%), trees (43.1%), birch (34.8%), short ragweed (30.8%), molds (29.7%), other trees (25.6%), dog (...

Objective: The objective of this prospective study was to compare assessments of pre- and post-ventilation-perfusion (V/Q) scan probabilities for pulmonary embolism (PE) by the nuclear medicine physician and the referring physician. Materials and Methods: Seventy-nine patients (41 females, 38 males, mean age 49 years) referred for V/Q scans over a period of 6 months and suspected of PE were included in the study. The pre-test likelihood was determined independently by a consultant nuclear physician and a referring physician prior to the V/Q scan. The scan was performed according to a standard protocol using 8 view technetium-99m diethylenetriamine pentaacetic acid aerosol ventilation study followed by a technetium-99m macroaggregated albumin perfusion study. The scan was interpreted according to prospective investigation of pulmonary embolism diagnosis criteria. The post-scan probability was calculated. The probability of PE was quoted as low, intermediate and high. Agreement or disagreement in assessing the pre- and post-scan probability was classified according to the degree of difference (no difference: 0; minor difference: 1, and major difference: 2 grades). Results: The agreement between the nuclear medicine and referring physicians on clinical probability of PE was moderate (63%) before the scan and good (90%) after the scan. The disagreement in assessing the clinical probability between the referring physician and the nuclear medicine physician was predominantly minor. Only 5 and 1% of the disagreement was major in pre-scan and post-scan probabilities, respectively. Conclusion: The data show that nuclear medicine physicians can use the assessment of pre-scan clinical likelihood to determine the post-scan probability of PE.
