The efficacy of topical Royal Jelly on diabetic foot ulcers healing: A case series*

Background: Foot ulcers and infections are the major sources of morbidity in individuals with diabetes mellitus. This study aimed to evaluate the efficacy of topical Royal Jelly (a worker honey bee product) on healing diabetic foot ulcers. Methods: Diabetic patients with foot ulcers that were referred to our clinic at Khorshid Hospital, Isfahan, Iran; were evaluated three times a week and treated according to standard treatments consisted of offloading, infection control, vascular improvement and debridement if required. In addition, all ulcers were measured and then topical sterile 5% Royal Jelly was applied on the total surface area of the wounds. Eventually, they were covered with sterile dressings. Each patient was followed for a period of three months or until the complete healing. Results: A total of eight patients were enrolled in this study. Of these, two had two ulcers and, therefore, ten ulcers were evaluated. Two ulcers were excluded. Seven of the remained eight ulcers healed. Mean duration of complete healing was 41 days. One ulcer did not completely heal but improved to 40% smaller in length, 32% in width and 28% in depth. The mean length, width and depth reduction rates were 0.35 mm/day, 0.28 mm/day and 0.11 mm/day, respectively. Conclusions: Royal Jelly dressing may be an effective method for treating diabetic foot ulcers besides standard treatments

Reference intervals for thyroid hormones during the first trimester of gestation: A report from an area with a sufficient iodine level

The physiological changes during pregnancy modulate the endocrine system. Therefore, both the American and the European thyroid associations recommend the use of local trimester-specific reference intervals. The purpose of this study was to establish the first trimester reference intervals for thyroid function tests in the central area of Iran. We examined 436 pregnant women in their first trimester of pregnancy, and 444 non-pregnant women in a cross sectional study. Serum levels of thyroid stimulating hormone (TSH), free thyroxin (FT4), free triiodothyronine (FT3), thyroid peroxidase antibody, urinary iodine concentration (UIC), and thyroid volume were measured for all subjects. The first trimester-specific reference intervals (2.5th–97.5th percentile) were determined for 185 pregnant women and 256 non-pregnant women with negative TPOAb, adequate iodine level (UIC≥150 μg/l in pregnant and UIC≥100 μg/l in non-pregnant women), and normal thyroid examination. We calculated multiples of the median (MoM) for TFTs to normalize the obtained data. The first trimester-specific reference intervals of serum TSH, FT4, and FT3 for pregnant women were 0.20–4.60 mIU/l, 9.0–18.02 pmol/l, and 3.40–5.64 pmol/l, respectively, while the corresponding figures for non-pregnant women were 0.59–5.60 mIU/l, 9.52–19.30 pmol/l, and 3.70–5.55 pmol/l, respectively. The first and 99th percentile MoM of TSH in pregnant women in their first-trimester was 0.06–4.62. The local normal reference ranges for the first trimester of pregnancy in central region of Iran were different from the ranges suggested by the ATA
