Randomized Controlled Trial Clinical Trial
Bedtime uncooked cornstarch supplement prevents nocturnal hypoglycaemia in intensively treated type 1 diabetes subjects.
The present study tests two interrelated hypotheses: (1) that bedtime ingestion of uncooked cornstarch exerts a lower and delayed nocturnal blood glucose peak compared with a conventional snack; (2) that bedtime carbohydrate supplement, administered as uncooked cornstarch, prevents nocturnal hypoglycaemia without altering metabolic control in intensively treated type 1 diabetes (IDDM) patients. ⋯ Uncooked cornstarch, ingested at bedtime, mimicked the nocturnal glucose utilization profile following insulin replacement, with a peak in blood glucose after 4 h. In IDDM patients, bedtime uncooked cornstarch supplement diminished the number of self-estimated hypoglycaemic episodes, without adversely affecting HbA1c and lipid levels. Hence, bedtime uncooked cornstarch ingestion may be feasible to prevent a mid-nocturnal glycaemic decline following insulin replacement in IDDM and, based on the nocturnal blood glucose profile, may also be preferable compared with conventional snacks.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of metoprolol and morphine in the treatment of chest pain in patients with suspected acute myocardial infarction--the MEMO study.
To compare the analgesic effect of metoprolol and morphine in patients with chest pain due to suspected or definite acute myocardial infarction after initial treatment with intravenous metoprolol. ⋯ In suspected acute myocardial infarction, if chest pain persists after intravenous beta-adrenergic blockade treatment, standard doses of an opioid analgesic such as morphine will offer better pain relief than increased dosages of metoprolol.

To determine the association of serum levels of lipoprotein (a) (Lp(a)) with coronary artery disease (CAD) in relation to other risk factor variables in black and white women. ⋯ Lp(a) is an important risk factor for CAD both in black and in white women.

Haemangioblastoma of the central nervous system (CNS) is the most characteristic lesion and the most common presenting manifestation of von Hippel-Lindau (VHL) disease and has a striking tendency to multiple occurrence. Its sites of predilection are the posterior fossa (cerebellum++), and the spinal cord. Haemangioblastoma may cause increased intracranial pressure and/or neurological deficits and remains the main cause of morbidity and mortality in VHL. ⋯ From a fundamental point of view, haemangioblastoma is a benign neoplastic entity with a double, vascular and cellular differentiation. Mutational inactivation of both copies of the VHL gene plays a major role in the pathogenesis of haemangioblastoma. Over-expression of vascular endothelial growth factor (VEGF) and VEGF-receptors has been recently demonstrated in these tumours, raising the possibility of angioblastic origin, and is of very great interest in view of the direct implication of the VHL gene in negative regulation of VEGF.

We herein report a case of a 40-year-old Japanese woman (patient IT) with a history of recurrent aggravation of hypertriglyceridaemia, pancreatitis and miscarriages in three previous pregnancies. However, strict dietary intervention was applied during a fourth pregnancy. As a result, acute pancreatitis was avoided, and the patient gave birth to a healthy infant. ⋯ She was homozygous for LPL deficiency due to a nonsense mutation (TGG1401 --> TGA/Trp382 --> Stop) in exon 8 of the LPL gene, which resulted in the absence of LPL activity and immunoreactive LPL mass. Our findings indicate that, in LPL deficiency, pregnancy seriously exacerbates hypertriglyceridaemia and increases the risk of acute pancreatitis, which endangers both the mother and fetus. Early diagnosis of LPL deficiency and appropriate management thereof are essential for normal childbirth.
