ABSTRACT

Background: Inducing puberty in hypogonadal patients enables achieving normal final adult height and healthy bone mass accrual and improves fertility potential. Reliable availability and access to medicines remain a challenge around the world, particularly in low-income countries. Aim: We aimed to describe the availability/access to medications used for inducing and maintaining puberty in centers within the Arab region. Method: A cross-sectional survey was conducted using a link to an online questionnaire, which was emailed to paediatric endocrinologists in the Arab region. The questionnaire consisted of three questions related to the availability of various forms of sex hormones. Results: 99 physicians from 16 countries participated in the study. The commonest available form of estrogen was conjugated estrogen (29% of centers), followed by ethinylestradiol (26%). Depot estradiol was available in 11 centers, while topical estrogen preparations of gel and patches were available in 6 and 10 centers, respectively. Medroxy progesterone was available in 26% of the centers, followed by norethisterone (24%). The combined forms of oral and transdermal patches of estrogen/progesterone were available in 35% and 9% of centers, respectively. Intramuscular testosterone (Sustanon) was the most commonly available preparation of testosterone, followed by the depot injection (Nebido), oral testosterone, and testosterone gel and cream. Conclusions: We report the first available data on medications used for puberty induction and maintenance in paediatric hypogonadism in the Arab region. Recommended preparations for this purpose are not widely available. Creating an essential list of medications used in paediatric endocrinology disorders might improve availability, access, and consequently practice.

ABSTRACT

BACKGROUND: Neck metastasis is the most important prognostic factor in oral cavity squamous cell carcinomas (SCC). Apart from the T- stage, depth of invasion has been used as a highly predictable factor for microscopic neck metastasis, despite the controversy on the exact depth cut off point. Depth of invasion can be determined clinically and radio logically. However, there is no standard tool to determine depth of invasion preoperatively. Although MRI is used widely to stage the head and neck disease, its utility in depth evaluation has not formally been assessed. OBJECTIVE: To compare preoperative clinical and radiological depth evaluation in oral tongue SCC using the standard pathological depth. To compare clinical and radiological accuracy between superficial (<5 mm) vs. deep invaded tumor (≥5 mm) METHODS: This prospective study used consecutive biopsy-proven oral tongue invasive SCC that presented to the University health network (UHN), Toronto. Clinical examination, radiological scan and appropriate staging were determined preoperatively. Standard pathology reports postoperatively were reviewed to determine the depth of invasion from the tumor specimen. RESULTS: 72 tumour samples were available for analysis and 53 patients were included. For all tumors, both clinical depth (r = 0.779; p < 0.001) and radiographic depth (r =0.907; p <0.001) correlated well with pathological depth, with radiographic depth correlating slightly better. Clinical depth also correlated well with radiographic depth (r = 0.731; p < 0.001). By contrast, for superficial tumors (less than 5 mm on pathological measurement) neither clinical (r = 0.333, p = 0.34) nor radiographic examination (r = - 0.211; p = 0.56) correlated with pathological depth of invasion. CONCLUSION: This is the first study evaluating the clinical assessment of tumor thickness in comparison to radiographic interpretation in oral cavity cancer. There are strong correlations between pathological, radiological, and clinical measurements in deep tumors (≥5 mm). In superficial tumors (<5 mm), clinical and radiological examination had low correlation with pathological thickness.
