Capillary haemoglobin levels of 12.0-12.5 g/dl in healthy females or 13.0-13.5 g/dl in healthy males are substantively equivalent to venous haemoglobin levels of > or = 12.5 and > or = 13.5 g/dl for women and men respectively. This finding has permitted an additional 32 990 blood units to be collected over the period of the study, a gain of 9.4%.
EBIR applicants were predominantly male (>95%). Clinical training, prior to radiology training, was very common in this cohort. Overall, most candidates expressed satisfaction with the examination process, and many felt this qualification helped their career. The recent recognition by national accreditation bodies should hopefully improve the profile of the examination greatly.
Intraneural ganglia are rare non-neoplastic cysts that are caused by an accumulation of thick mucinous fluid. This occurs within the epineurium of peripheral nerves, which is encased in a dense fibrous capsule. The most common presentation of this tumour is local and/or radiating pain. Involvement of the tibial nerve is extremely uncommon, with less than 18 reported cases in the literature. We present a case of an intraneural tibial nerve ganglion cyst in a young male. We also discuss the current literature and proposed pathogenesis and treatment of this rare entity.
Background and aims
This retrospective cohort study evaluated the degree of pelvic inflow and internal pudendal artery (IPA) calcification in male smokers versus non-smokers. As erectile dysfunction (ED) is strongly associated with IPA vascular, we wanted to investigate radiologically if there was a statistically significant difference in the degree of IPA calcification in smokers and potentially be a contributing factor in the cause of ED.
Methods
CT studies of 100 men aged between 40 and 60 years of age were blindly reviewed and assigned a calcium score of their vascular calcification levels. We compared scores of 50 smokers versus 50 non-smokers. The Mann Whitney U test statistic was used to test for a statistical difference in calcification score between the smoking and non-smoking groups.
Results
Results show a statistically significant association between smoking and pelvic inflow and IPA calcification. The Mann Whitney U test demonstrated a statistically significant higher calcium score in the smoking group (mean = 4.8, SD 3.7), versus the non-smoking group, (mean = 1.8, SD 1.9) (U = 701.5, p < 0.05).
Conclusions
This research is the first of its kind based on an extensive literature review. The association between vascular calcification and smoking is well established, in addition to the direct relationship of IPA calcification and ED. This unique study has demonstrated an increased rate of IPA calcification in smokers with a potential inferred association with ED. Findings represent a novel and useful deterrent for health authorities to include in anti-smoking campaigns.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
