A study of 100 cases of vitiligo showed the frequency of associated skin and visceral lesions. A skin disease was associated in 24 cases: psoriasis 4 cases, alopecia 4 cases, eczema 3 cases, malignant melanoma 2 cases, dermatitis herpetiformis 1 case, lichen planus 9 cases. However, only one case of Sutton's naevus was noted. Among other associations noted in 28 cases, there were 7 cases of thyroid disease, 5 cases of diabetes, 1 case of chronic rheumatoid arthritis and 3 gastric disorders. The frequency of these various associations was discussed in the light of other authors' reports. If one compares the 21 cases associated with auto-immune disease and the other cases of vitiligo, there was no significant difference for the various parameters studied. Thus the significance of the various biological signs of autoimmunisation remains doubtful and even the precise definition of vitiligo remains uncertain.

From 1969-1974 1000 unselected enucleated globes have been examined histopathologically. 277 derive from the University Eye Hospital in Hamburg, 723 from various Eye Hospitals in northern and southern Germany. They originate from 589 men and 408 women, three times the sex was unknown. 86 globes had to be removed from children less than 15 years old. 6 groups of etiologies have been distinguished: trauma (308), histologically confirmed neoplastic disease (281), ocular manifestations of systemic diseases (diabetes mellitus, occlusions of central retinal vessels presumably following generalized vascular disease etc.: 128), "operative ocular disease" (164), primary inflammatory disease (71), miscellaneous (malformations, high myopia, pseudo-glioma and pseudo-melanoma: 48). The etiology "operative ocular disease" consists of 67 primary glaucomas (57 adults, 10 buphthalmus), 41 idiopathic cataracts (7 of these congenital) and 3 primary corneal dystrophies, as well as 53 cases of primary retinal detachment. Among the 281 neoplastic diseases, there are 238 primary intraocular malignant melanomas of the uvea, 18 retinoblastomas, 4 primary reticulumcellsarcomas of the retina, 2 choroidal nevi, 10 intraocular metastases and 9 orbital tumors. 16 enucleations among the 1000 enucleations have been performed for pseudo-gliomas (5 x Coats disease, 5 x persistent primary hyperplastic vitreous, 2 x retrolental fibroplasia, others 4 x). The manifestations of systemic disease are consisting of 68 central retinal vein-occlusions, 30 complications of diabetes mellitus and 10 central retinal artery occlusions as well as 20 other generalized diseases. A primary inflammatory disease led to enucleation 50 times due to an intraocular process, 5 times due to scleritis and 18 times as a consequence of keratitis (including 13 times herpes simplex). As the final clinical cause for enucleation the following categories have been elaborated: secondary glaucomas (416), clinical diagnosis of "tumor" (275), atrophy and phthisis bulbi (118), inflammation (112), acute trauma to 4 weeks after the accident (72), others (7). In conclusion the central role of rubeosis iridis leading to secondary angle closure glaucoma is emphasized. This process presents a challenge to ophthalmologic research. Finally the significance of early surgery for primary angle closure glaucomas and for complete restoration of the anterior chamber after trauma and any intraocular procedure is stressed.

A patient with adult-onset diabetes mellitus was referred with a diagnosis of malignant melanoma of the choroid of the left eye. A nonproliferative type of diabetic retinopathy was present, which was studied and documented by stereoscopic fundus photographs and fluorescein angiograms. Following enucleation, the microangiopathies were correlated histologically, using the retinal trypsin digest technique. Four types of microaneurysms were seen histologically that were believed to represent stages in the development of this lesion. Most thin-walled aneurysms tightly packed with erythrocytes did not fluoresce. Aneurysms that were hypercellular and those with thick walls showed early and late fluorescence. Intraretinal microvascular abnormalities were hypercellular dilated channels. Those that take origin from terminal arterioles are believed to represent attempts at neovascularization.

50 patients with congenital rubella, born in 1939-43, were reviewed in 1967. Here we report their outcome in 1991. Since 1967, there have been 7 deaths (3 cardiovascular, 3 malignant disease, 1 AIDS). 40 had full clinical assessment. The prevalence of diabetes mellitus is similar to that in 1967: 4 of the 5 reported diabetic then, remain so, and there is 1 new case. 1 subject has malignant melanoma and 3 have died from cancer. Although the incidence of malignant disease is not increased, the death rate is (standardised mortality rate 6.0, 95% CI 1.24-17.57). Longer follow-up will be required to confirm this observation.

Life-style has a major influence on the incidence of breast cancer. To evaluate the effects of life-style related metabolic-endocrine factors on breast cancer risk we conducted a case-control study comparing 223 women aged 38 to 75 years presenting with operable (stage I or II) breast cancer and 441 women of the same age having no breast cancer, who participated in a population-based breast cancer screening program. Women reporting diabetes mellitus were excluded. Sera from 110 women of the same age group presenting with early stage melanoma, lymphoma or cervical cancer were used as a second 'other-cancer control group'. Serum levels of C-peptide were significantly higher in early breast cancer cases compared to controls. The same was found for the ratios C-peptide to glucose or C-peptide to fructosamine, indicating insulin resistance. Sex hormone binding globulin was inversely, triglycerides and available estradiol were positively related to C-peptide. Serum C-peptide levels were related to body mass index (BMI), and to waist/hip ratio (WHR), in particular in controls. However, the relative increase of C-peptide, C-peptide to glucose or C-peptide to fructosamine in cases was independent of BMI or WHR. The log relative risk was linearly related to the log C-peptide levels. Relative risk according to quintiles, and adjusted for age, family history, BMI and WHR, for women at the 80% level was 2.9 as compared with those at the 20% level for C-peptide. Elevated C-peptide or C-peptide to fructosamine values were not observed in the sera from women belonging to the 'other-cancer control group'. This study suggests that hyperinsulinemia with insulin resistance is a significant risk factor for breast cancer independent of general adiposity or body fat distribution.

The general practitioners in the Canterbury Area Health Board area were surveyed for their screening policies for cancer and medical conditions. Responses were obtained from 210 (79%), 55% of whom had age/sex registers. Ninety-seven percent provided cervical smears, usually at 1-2 year intervals; 62% offered a female smear taker. Smears were initiated opportunistically by 76%, by age/sex register (47%) or on request by 27%. Breast cancer was screened by 69% using mammography and by 59% using breast physical examination; 73% taught breast self examination. Mammography was recommended every two years for women aged 50-64 years by 45% of responders, and annually to women aged 40-50 years by 19%. Mammography was initiated opportunistically by 88%, on request by 70% and using an age/sex register by 21%. Melanoma was screened by 66%, colorectal cancers in those at high risk by 42%. Testicular self examination was promoted by 43%. Ninety-one percent screened for hypertension, and 51% for hyperlipidaemia, 54% for diabetes mellitus in people without risk factors. Smoking (97%) and alcohol intake (82%) were usually inquired for, and safe sex practices by 59%. Established screening modalities were recommended by most practitioners, but the frequency exceeded current guidelines in many cases; opportunistic screening predominated.

Predisposing factors to cervical cancer development are age, smoking, socioeconomical status, parity, and number of sex partners. Long-term oral contraceptive (OC) use and less than 50 mg estrogen dose have been weakly linked to increased cancer risk. Regular examination and switching to other contraception in case of cervical intraepithelial neoplasia is recommended. Estrogen in sequential pills (Ovacon) increases the risks of uterine cancer by affecting the mucosa. Predisposing factors are: absence of pregnancy (nulliparity), postmenopause, hypertension, and diabetes. Parity reduces the risk. The risk is reduced in combined pills and after use of 1 year. Protection is offered by the progesterone component for 10-20 years after cessation of use. Ovarian cancer is prevented by parity and OC use even 10 years later. High estrogen levels inducing frequent ovulation damage the ovaries. Promoting factors are: old age, avoidance of breast feeding, and overweight. Breast cancer promoters are 1st pregnancy in older age, early menarche, and no pregnancy at all. OC use under age 25 and before 1st pregnancy are significant risk factors. High progesterone levels are associated with increased mitotic activity in the breast. Rare benign fibrocysts can develop into breast cancer. OC use is connected to hepatoma development mainly estrogen-induced. Liver cancer was found twice as high in OC users. Hepatoma often ruptures causing hemorrhage. 8% of liver tumors are malignant with a survival rate of 50% of patients to 4.8 years. The possible association of OCs to skin melanoma and hypophysial tumors could not be confirmed. OCs regulate menstruation, reduce bleeding, protect against uterine and ovarian cancer, but cervical and breast cancers have been influenced by them.

The insulin receptor contains in its beta-subunit a tyrosine (-) specific protein kinase. It is believed that transmission of an insulin signal across the plasma membrane of target cells of insulin action occurs through activation of this kinase, autophosphorylation of the insulin receptor beta-subunit and subsequent phosphorylation of other cellular substrates. We studied the insulin receptor kinase in a number of insulin resistant cell systems in order to elucidate if defects of this kinase are a possible cause of cellular insulin resistance. Three different patterns of kinase abnormalities were found, in different insulin resistant cells: 1. In an insulin resistance melanoma cell line a reduced receptor kinase autophosphorylation was found apparently due to a defect of the tyrosine autophosphorylation sites of this receptor; 2. Catecholamine and phorbol ester induced insulin resistance of isolated rat fat cells as well as human fat cells was associated with a decreased activity of the insulin receptor tyrosine kinase which was apparently due to a modulation of the ATP binding site of the insulin receptor tyrosine kinase; 3. The receptor kinase isolated from the skeletal muscle of diabetic Zucker rats (fa/fa) was found to be insulin insensitive with no major alteration of maximal responsiveness. These results suggested that different forms of kinase defects exist which can contribute to the pathogenesis of cellular insulin resistance. Based on these data studies in skeletal muscle from type II diabetic patients were started. Results from five patients so far suggest that, here as well, an abnormality of the insulin receptor kinase exists which might be involved in the pathogenesis of insulin resistance in type II diabetes.

Hospital admissions, cancer statistics, causes of death and data from general practice consultations have been reviewed to identify the challenges to health within the working life. Morbidity resulted commonly from trauma, malignant neoplasms especially of the female breast, melanoma, colorectal and cervical tumours, locomotor disorders especially of the spine, ischaemic heart disease, obstructive respiratory disorder, gynaecological problems, psychiatric disorders, hearing impairment and diabetes mellitus. Support for basic research and studies relating to approaches aimed at influencing community attitudes are discussed. Areas of particular research possibilities in New Zealand are identified in psychiatry, cost benefit studies in surgery, and health screening. A case is made for a strong improved complementary research effort within the clinical areas of the health service both in hospitals and in general practice especially in clinical conditions such as asthma and diabetes. Seeding money for voluntary societies and foundations closely involved with research and scientific merit may facilitate further financial support to such voluntary organisations and the prospect of expansion by them of the support of peer-reviewed research projects.

Recurrent eruptions of small, black nodules resembling metastases of malignant melanoma in a 64-year-old male patient with diabetes mellitus are reported. Clinically, the lesions seemed to be angiomas. Histological examination revealed capillary aneurysms. To date there has been no spontaneous regression. Sclerosing injections or compression therapy had no effect. Only total excision of lesions was successful. The etiology of the disease is unknown. The patient had diabetic retinopathy with increased plasma levels of cholesterol.
