Improved Glycaemic Control

Over the last 10 years, intensified insulin regimens have been developed in the hope that improved glycaemic control will help prevent diabetic complications. The regimens involve either continuous subcutaneous insulin infusion (CSII) via a motorised pump1 or, more commonly, multiple subcutaneous injections. The multiple injection regimens usually consist of a short-acting insulin before meals with long or medium-acting insulin at bedtime (‘basal-bolus’ regimens). Pen-like injectors, which simplify the transport and injection of insulin, were developed to make these multiple dose regimens more acceptable and convenient. They are also increasingly being used with twice daily, mixed insulin regimens.

Ad Libitum

Acute thiamine deficiency was produced in mice by the administration of oxythiamine, a thiamine analogue, superimposed upon a thiamine deficient diet. Adult male Swiss mice (30 gm. B.W.) were fed with a thiamine deficient diet ad libitumand were injected with oxythiamine (170 mg/Kg B.W.) subcutaneously on days 4 and 10. On day 11, severe lassitude and anorexia developed, followed by death within 48 hours. The animals treated daily with subcutaneous injections of thiamine (300 μg/Kg B.W.) from day 11 through 15 were kept alive. Similarly, feeding with a diet containing thiamine (600 μg/Kg B.W./day) from day 9 through 17 reversed the condition. During this time period, no fatal illness occurred in the controls which were pair-fed with a thiamine deficient diet.The oxythiamine-treated mice showed a significant enlargement of the liver, which weighed approximately 1.5 times as much as that of the pair-fed controls. By light and electron microscopy, the hepatocytes were markedly swollen due to severe fatty change and swelling of the mitochondria.

Hypophysectomized Rats

ABSTRACT Measurements of plasma corticosteroid levels and adrenal ascorbic acid concentration in steroid blocked and hypophysectomized rats were performed. It was found that prednisolone and dexamethasone were effective in blocking endogenous corticotrophin release within 3–4 hours after subcutaneous injection. These agents also prevented completely the normally occurring rise in plasma corticoid levels after exposure of the rats to ether. Abdominal surgery (unilateral adrenalectomy) resulted in a slight but significant rise in plasma corticoid levels in spite of dexamethasone blockade. The values of adrenal ascorbic acid were not affected significantly. The blocking effect of two daily subcutaneous injections of a high dose of dexamethasone persisted for about one week after the last injection. The sensitivity of the plasma corticoid response was essentially the same in hypophysectomized and dexamethasone blocked rats. The lower part of the log dose response curve was found to be clearly non-linear in the plasma corticoid method following intravenous corticotrophin injection. As a consequence the dose level in quantitative assays of intravenously injected corticotrophin are, in our hands, of the same order as in the adrenal ascorbic acid depletion method.

Background: Adherence to subcutaneous biologic agents for the treatment of psoriasis can be negatively influenced by injection pain.Objective: To explore the differences in injection site pain when patients are pre-treated with heat or cold, versus no pre-treatment prior to administration of a subcutaneous biologic agent.Methods: In an observational cohort study, patients receiving subcutaneous injections of ustekinumab were randomly assigned to receive pretreatment with ice, heat, or no intervention over three visits. Post-dose, patients rated pain on a 100 mm visual analogue scale (VAS).Results: There was an increase in the VAS score for both heat (2.51, P=0.30) and ice (3.33, P=0.16), compared to no intervention. No differences were found between the two intervention groups (-0.83, P=0.73). On average, females had the same VAS scores with ice compared to that of no intervention (-0.12, P=0.97) and a non–significant decrease of 3.29 points (P=0.38) with heat. Males had increased pain scores by 5.65 points (P=0.07) with ice and by 6.39 points (P=0.04) with heat.Limitations: Pain is a subjective measurement and objective quantification is difficult.Conclusions: On average, neither heat nor cold application reliably reduced pain. Our results do not support the application of heat or cold prior to ustekinumab injection.
