Nocturnal Vulval Pain in Girls-A Subset of Vulvodynia?

OBJECTIVES: The aims of the authors' case series were to outline the clinical features of prepubertal nocturnal vulval pain syndrome and to look at management and outcomes. METHODS: Clinical details of prepubertal girls experiencing episodes of nocturnal vulval pain with no identifiable cause were recorded and analyzed. Parents completed a questionnaire to look at outcomes. RESULTS: Eight girls with age at onset of symptoms between 3.5 and 8 years (mean 4.4 years) were included. Each patient described intermittent episodes of vulval pain lasting between 20 minutes and 5 hours, starting 1-4 hours after falling asleep. They were crying and rubbing or holding the vulva with no obvious cause seen. Many were not fully awake and 75% had no recollection of the events. Management focused on reassurance alone. The questionnaire showed that 83% had full resolution of symptoms with a mean duration of 5.7 years. CONCLUSIONS: Prepubertal nocturnal vulval pain syndrome may be a subset of vulvodynia (generalized, spontaneous, intermittent) to be included in the clinical spectrum of night terrors. Recognizing the clinical key features should aid prompt diagnosis and reassurance of the parents.

Diabetic Nephropathy: An Overview.

Diabetic nephropathy (DN) is one of the most feared diabetic chronic microvascular complications and the major cause of end-stage renal disease (ESRD). The classical presentation of DN is characterized by hyperfiltration and albuminuria in the early phases which is then followed by a progressive renal function decline. The presentation of diabetic kidney disease (DKD) can vary especially in patients with T2DM where concomitant presence of other glomerular/tubular pathologies and severe peripheral vascular disease can become important confounders. All-cause mortality in individuals with DKD is approximately 30 times higher than that in diabetic patients without nephropathy and a great majority of patients with DKD will die from cardiovascular disease before they reach ESRD. The management of metabolic and hemodynamic perturbations for the prevention and for the delay of progression of DKD is very important. DKD is a global challenge and a significant social and economic burden; research should aim at developing new ideas to tackle this devastating condition.

Diabetic nephropathy: Is there a role for oxidative stress?

Oxidative stress has been implicated in the pathophysiology of diabetic nephropathy. Studies in experimental animal models of diabetes strongly implicate oxidant species as a major determinant in the pathophysiology of diabetic kidney disease. The translation, in the clinical setting, of these concepts have been quite disappointing, and new theories have challenged the concepts that oxidative stress per se plays a role in the pathophysiology of diabetic kidney disease. The concept of mitochondrial hormesis has been introduced to explain this apparent disconnect. Hormesis is intended as any cellular process that exhibits a biphasic response to exposure to increasing amounts of a substance or condition: specifically, in diabetic kidney disease, oxidant species may represent, at determined concentration, an essential and potentially protective factor. It could be postulated that excessive production or inhibition of oxidant species formation might result in an adverse phenotype. This review discusses the evidence underlying these two apparent contradicting concepts, with the aim to propose and speculate on potential mechanisms underlying the role of oxidant species in the pathophysiology of diabetic nephropathy and possibly open future more efficient therapies to be tested in the clinical settings.
