Needle phobia in patients with Type 1 (insulin-dependent) diabetes mellitus is difficult to manage. We report a case of long-standing needle phobia in a patient with 33 years of Type 1 diabetes mellitus who has developed very few vascular complications. Further studies are required to identify the p

Abstract
We have investigated the properdin factor B (BF) locus as a possible marker for Type 1 diabetes. The frequencies of the four BF alleles were determined among 70 Type 1 diabetics with onset before age 18 years. The frequency of BF F1 among the diabetics was increased compared with 206 controls (15.7 vs 3.4%). The relative risk (RR) associated with BF F1 was 5.30. The suggestion that BF F1 is most strongly associated with onset of diabetes under 10 years of age was not supported. HLAB 18 was increased (RR = 4.91) and B 7 was decreased in frequency (RR = 0.41) among the 62 diabetics tested compared with 238 controls. An association was observed between HLAB 18 and BF F1 among the diabetics. A study of 12 families in which BF*F1 was segregating suggested that BF*F1 and HLAB*18 are components of a haplotype associated with Type 1 diabetes in this population and that both haplotypes of an affected parent may contribute to the development of Type 1 diabetes.

Various environmental triggers, e.g. certain viruses and dietary factors, are thought to initiate the autoimmune process, leading to the destruction of pancreatic beta-cells and consequent Type 1 diabetes. A genetic predisposition is another prerequisite allowing the autoimmune process to progress.
We investigated autonomic function in 58 children and young adults with Type 1 diabetes mellitus (aged 7-22 years, duration from 3 to 18, 8.6 Β± 3.4 years) and in 74 healthy controls (6-21 years) using power spectral analysis of blood pressure and heart rate in addition to conventional standard auton
