Superficial folliculitis of the scalp (SFS) is a common complaint in clinical practice, and initial presentation may be difficult to differentiate as they may appear very similar to each other. The aim of this thesis is to describe the pathologies that occur clinically as folliculitis of the scalp, identify their causes and characteristics and create a standardized classification. This is a retrospective clinical, dermoscopic and histopathological study over 10 years of dermatologic consultations. Only individuals with a confirmed diagnosis of SFS (updated diagnostic criteria or biopsy) were included. In this review, we describe the various clinical features of different causes of SFS in ninety-nine cases and divided into infectious due to fungus, bacteria, or virus and inflammatory conditions such as rosacea, acneiform eruption and Ofuji syndrome. The clinician must differentiate SFS from other underlying scarring disorders to prevent poorer outcomes. We created an algorithm to help the clinician reach a proper diagnosis.

BackgroundWellington-Dufferin-Guelph Public Health (WDGPH) has conducted an absenteeism-based influenza surveillance program in the WDG region of Ontario, Canada since 2008, using a 10% absenteeism threshold to raise an alert for the implementation of mitigating measures. A recent study indicated that model-based alternatives, such as distributed lag seasonal logistic regression models, provided improved alerts for detecting an upcoming epidemic. However model evaluation and selection was primarily based on alert accuracy, measured by the false alert rate (FAR), and failed to optimize timeliness. Here, a new metric that simultaneously evaluates epidemic alert accuracy and timeliness is proposed. The alert time quality (ATQ) metric is investigated as a model selection criterion on both a simulated and real data set.MethodsThe ATQ assessed alerts on a gradient, where alerts raised incrementally before or after an optimal day were considered informative, but were penalized for lack of timeliness. Summary statistics of ATQ, average alert time quality (AATQ) and first alert time quality (FATQ), were used for model evaluation and selection. Alerts raised by ATQ and FAR selected models were compared. Daily elementary school absenteeism and laboratory-confirmed influenza case data collected by WDGPH were used for demonstration and evaluation of the proposed metric. A simulation study that mimicked the WDG population and influenza demographics was conducted for further evaluation of the proposed metric.ResultsThe FATQ-selected model raised acceptable first alerts most frequently, while the AATQ-selected model raised first alerts within the ideal range most frequently.ConclusionsModels selected by either FATQ or AATQ would more effectively predict community influenza activity with the local community than those selected by FAR.

Information concerning risk factors associated with Giardia infection in dogs in southern Ontario, Canada, is currently lacking. This study therefore aimed to identify risk factors for Giardia infection in dogs that visit off-leash dog parks in southern Ontario. From May–November 2018, fecal samples were collected from 466 dogs in 12 off-leash dog parks in the Niagara and Hamilton regions of Ontario. A survey that asked questions pertaining to travel history (i.e., area of residence, locations and regions visited in the previous 6 months), basic medical history (i.e., spay/neuter status, veterinary visits, use of deworming medication), consumption of a raw diet, and the physical (i.e., age, sex, breed) and behavioral characteristics (i.e., off-leash activities, hunting activities) of each dog sampled was administered to the respective owner. All fecal samples were examined with the Giardia plate ELISA (IDEXX Laboratories) for parasite antigen. Multivariable logistic regression analyses were conducted on the survey data to investigate putative risk factors for Giardia infection. Overall, 11.8% (95% CI: 9.2–15.1%) of samples tested positive for Giardia antigen. Results from the multivariable logistic regression analyses identified an interaction between dog age and spay/neuter status that was significantly associated with Giardia infection. The odds of infection were greater in intact as compared to neutered adult dogs (OR: 3.6, 95% CI: 1.7–7.9, p = 0.001), and in neutered juvenile dogs as compared to neutered adults (OR: 5.2, 95% CI: 2.2–12.2, p < 0.001). The results provide veterinarians with evidence-based information for identifying dogs at greatest risk of Giardia infection in southern Ontario.

Community-engaged learning is used in Master of Public Health programs to enhance student training, connect with communities, help solve societal issues, develop competencies, and build partnerships. However, it is unclear how much community-engaged learning components supplement existing Master of Public Health programs and prepare students in developing these competencies. Thus, the aim of this study was to apply an explanatory mixed-methods study design to evaluate a Canadian Master of Public Health program's community-engaged learning activities and propose recommendations to strengthen public health training and course delivery. We conducted a questionnaire among Master of Public Health students (n = 25), focus group discussion with a subset of these students (n = 7), and one-on-one semi-structured telephone interviews with community partners who had previously hosted Master of Public Health students for practicum placements (n = 11). Community-engagement enhanced learning among Master of Public Health students, with the practicum placement, and program development capstone resulting in the largest self-reported development. Students in the focus group indicated community engagement provided skill and professional development, but also identified wanting additional curriculum coverage on various statistical software and qualitative research methods. Interviews with community partners revealed benefits of practicum placements such as mutual knowledge transfer, increased organizational capacity, and strengthened academic-community partnerships. Community partners also commented on challenges with recruitment, training, and aligning student-organization goals. The findings from this study suggest that an update to the Master of Public Health program curriculum, its core competencies, a combination of community-engagement activities, and future evaluations will be needed to advance education delivery.

Despite the growing understanding of preconception care, numerous barriers to its delivery still exist, including a lack of evidence-based, accessible screening tools. To validate a new digital Preconception Health Assessment Tool (PreCHAT) against the current best practice, physician-delivered tool in Ontario, Canada, and explore how PreCHAT's design impacts its risk identification abilities relative to the comparison tool. A criterion validation study was conducted with 53 female participants aged 18-44 years. Participants completed both tools in a controlled setting. PreCHAT was completed on a tablet individually by participants, while the comparison tool was administered by a physician. Three physicians administered the comparison tool. Measures of strength of agreement between PreCHAT and the comparison tool were calculated using percent agreement, Cohen's Kappa, and prevalence-adjusted and biased-adjusted kappa (PABAK). PreCHAT identified 135 individual risk factors, while the comparison tool identified 102. Both tools shared the same 14 domains of preconception care and 88 risk factors; of the 88 risk factors, PreCHAT identified an average of 3.42 (p < 0.0001) more risks per participant than the comparison tool. PABAK scores indicated almost perfect agreement between PreCHAT and the comparison tool. This study suggests that PreCHAT is valid against the current best practice tool and is broader in its risk identification among individuals of reproductive age. PreCHAT's patient-facing, digital, EMR-integrated design may offer unique benefits to providers and patients. PreCHAT offers providers an innovative approach to deliver preconception care and may positively impact reproductive, maternal, and child health.

Female Pattern Hair Loss (FPHL) is one of the most common types of hair loss in women. It is characterized by progressive follicular miniaturization leading to diffuse hair thinning over the midfrontal scalp with a negative impact on quality of life. Pharmacological treatments are commonly used, and hair follicle transplantation is an option for those cases with adequate donor area. Minimally invasive procedures, such as microneedling, mesotherapy, microinfusion of drugs into the scalp with tattoo machines (MMP®), and platelet-rich plasma (PRP) have been reported as adjuvant treatments. This study aims to summarize and discuss the efficacy of minimally invasive procedures described for the management of FPHL. Published articles indexed on the Pubmed database and Scopus that described minimally invasive procedures for the management of FPHL in humans were considered. Citations were reviewed and added for completeness. The search was for articles in English only. After excluding duplicate titles, 23 relevant articles were considered. Minimally invasive procedures are promising options and may play a role in FPHL treatment. They can be used as adjunctive therapy for FPHL, in case of poor response to clinical therapy, or when patients prefer other care than the standard. We reinforce that these methods should be performed by an experienced medical professional following strict aseptic techniques. However, microneedling, mesotherapy, MMP, and PRP lack standardization and are supported by a low level of evidence yet. For the future, larger randomized clinical trials are essential to determine the efficacy and optimal protocols for these treatments.

Primary angiosarcoma of the breast is a rare malignancy that is important for radiologists to recognize in young patients because its imaging appearance may mimic benign lesions resulting in advanced stages of disease and overall decreased patient survival. We present a unique case of a bilateral primary angiosarcoma in a pregnant patient in her twenties. She presented with a self-detected, rapidly enlarging, non-tender right breast mass while in her third trimester.
