Aid for Trade, Trade Costs and Export Diversification with Reference to Sub-Saharan Africa
Trade costs, which are significantly higher in sub-Saharan Africa (SSA) than in other regions of the world, constitute a potent explanation for the continent’s marginalisation in global trade and its vulnerability to external shocks due to heavy reliance on a few export commodities. This thesis develops a conceptual model to test the hypothesis that Aid for Trade (AfT) can reduce trade costs and spur export diversification in SSA, thereby helping the continent leverage its growth potential through trade
Scabies Associated with Granulomatous Dermatitis
Scabies is a relatively common parasitic infection, which has sometimes been associated with the formation of granuloma annulare. We report the case of an 86-year-old female who developed a non-necrotizing granulomatous dermatitis after a scabies infestation. This case highlights the importance of considering scabies in the differential diagnosis when granulomatous dermatitis is noted histologically that cannot be explained by other causes
Case Report of Leprosy in Central Florida, USA, 2022
Florida, USA, has witnessed an increased incidence of leprosy cases lacking traditional risk factors. Those trends, in addition to decreasing diagnoses in foreign-born persons, contribute to rising evidence that leprosy has become endemic in the southeastern United States. Travel to Florida should be considered when conducting leprosy contact tracing in any state
Between a rock and a hard place: management of systemic lupus erythematosus and porphyria cutanea tarda
Porphyria cutanea tarda (PCT), the most common porphyria, is a rare photodermatosis characterized by fragile, hemorrhagic bullae and erosions with associated milia, hyperpigmentation, and hypertrichosis. SLE is a systemic connective tissue disease with approximately 80% of those affected manifesting cutaneous findings. These include malar and discoid rashes, photosensitivity, bullae, oral ulcerations, as well as a variety of other nonspecific findings. In this case, we illustrate a rare but established association between these two pathologic entities, and the resulting therapeutic challenge in treating a patient with both conditions. The concurrence of these two diseases poses therapeutic challenges with a paucity of evidence-based recommendations. Management with low dose weekly antimalarial therapy may be the appropriate middle ground in effectively treating the two co-morbid conditions especially in a patient with other underlying systemic conditions

Comparing the efficacies of alginate, foam, hydrocolloid, hydrofiber, and hydrogel dressings in the management of diabetic foot ulcers and venous leg ulcers: a systematic review and meta-analysis examining how to dress for success
Diabetic foot ulcers and venous leg ulcers are chronic wounds frequently encountered by dermatologists. Choosing appropriate wound dressings can effectively promote wound healing and potentially reduce morbidity and financial burden experienced by patients. The objective of our systematic review and meta-analysis was to evaluate wound healing efficacies of synthetic active dressings in diabetic foot ulcer and venous leg ulcer management. For data collection, PubMed, Embase, Cochrane Library, CINAHL, and clinicaltrials.gov online databases were searched from database inception to 10 May 2015. Fixed and random effects modeling were used to calculate pooled risk ratios for complete ulcer healing from pairwise dressing comparisons. The results of our review showed moderate-quality level evidence that hydrogels were more effective in healing diabetic foot ulcers than basic wound contact dressings (RR 1.80 [95% CI, 1.27-2.56]). The other dressing comparisons showed no statistically significant differences between the interventions examined in terms of achieving complete diabetic foot ulcer healing. Non-adherent dressings were more cost-effective than hydrofiber dressings for diabetic foot ulcers in terms of mean total cost per patient of the dressings themselves. All venous leg ulcer pairwise dressing comparisons showed equivalent dressing efficacies in terms of promoting complete ulcer healing. Overall, most synthetic active dressings and traditional wound dressings are equally efficacious in treating diabetic foot ulcers and venous leg ulcers. For treating diabetic foot ulcers, hydrogels are more efficacious than basic wound contact dressings, and non-adherent dressings are more cost-effective than hydrofiber dressings. Ultimately, dressing choice should be tailored to the wound and the patien
