Treatment-induced neuropathy of diabetes (TIND) is an acute painful autonomic small-fiber neuropathy that develops following an abrupt improvement in glycaemia control. Recent reports suggest TIND is a significant problem in tertiary neuropathy clinics. TIND in hospitalized patients with poor initial glycaemia control, that we refer to as nosocomial TIND, has not been well-studied. We describe the demographic, clinical features and indices of glycaemia control in 5 consecutive nosocomial TIND patients. TIND was defined using recently published criteria. Pre-meal capillary blood glucose recordings performed during the period of HbA1c decline was used to calculate glycaemic variability. All the nosocomial TIND patients were hospitalized for prolonged periods for serious medical conditions that warranted good glycaemia control, namely severe sepsis, diabetic ketoacidosis, stroke, heart failure and traumatic head injury. They had raised, double-digit, HbA1c levels at admission that subsequently dropped precipitously with tight in-patient glycaemia control protocols. These patients had multiple, largely asymptomatic, hypoglycaemic episodes. Glycaemic variability also appeared to be high in this cohort. TIND may be a significant cause of morbidity in hospitalized diabetic patients with poor glycaemia control. Not all patients developed both autonomic and painful neuropathies, raising the possibility of forme-fruste TIND

INTRODUCTIONGenetic predisposition to clear cell renal cell carcinoma (ccRCC) has been linked to disorders such as von Hippel-Lindau (VHL) syndrome. While twin research is a classic approach for elucidating genetic and environmental contributions to disease, no monozygotic twin-pair concordant for ccRCC in the absence of VHL syndrome has been previously reported in the literature or in major twin registries.

CLINICAL PICTUREWe describe a unique monozygotic twin-pair concordant for ccRCC, with discordant but early ages of onset of 25 and 38 respectively. Cytogenetic studies and direct sequencing for VHL gene mutations in the second twin proved unremarkable.

CONCLUSIONSThis is the fi rst reported case of monozygotic twins concordant for ccRCC in the absence of VHL gene mutation. The early yet discordant, age of onset of disease in both twins suggests both genetic and environmental contributions to ccRCC.
