Type I multiple symmetrical lipomatosis (MSL; Madelung's disease) is characterized by lipomas in the nape of the neck and the supraclavicular and deltoid regions, resulting in a bull-necked appearance (Madelung's collar). It is most common in alcoholic men between 35 and 50 years of age. Type I MSL has been reportedly associated with hyperinsulinemia, but its association with diabetes mellitus is rarely discussed. We describe a case of non-insulin-dependent diabetes mellitus (NIDDM) associated with type I MSL. A 47-year-old alcoholic man presented with a seven-year history of hyperglycemia and progressive neck swelling with dysphagia for one year. Physical examination showed diffuse and symmetrical swelling of the bilateral posterior aspects of the neck. Biochemistry profiles revealed elevated concentrations of fasting serum glucose (276 +/- 16 mg/dl), triglycerides (358 +/- 79 mg/dl) and total cholesterol (323 +/- 28 mg/dl). Endocrinologic studies showed normal thyroid function. Neck sonography revealed diffuse thickening and swelling of the fatty structures of both sides of the neck. Normal sonography showed no fatty deposition in the liver. Maxillary and neck computerized tomography revealed diffuse fat accumulation in the submental and posterior neck regions, with no extension to the superior mediastinum. Fine needle aspiration cytology of the neck masses showed only fat cells. The patient received an oral hypoglycemic agent (glibenclamide 5 mg bid) for blood glucose control and lovastatin (20 mg before bed-time) for hyperlipidemia, and ceased drinking alcohol. The neck swelling resolved markedly after 15 months of medical treatment. This suggests that, in addition to the cessation of alcohol consumption, the reduction of blood glucose and lipid concentrations by medication may also assist in resolving the accumulated fat of type I MSL in patients with NIDDM.

Hyperlipemia in horses is a disorder of lipid metabolism peculiar to ponies. This study reports changes of blood biochemical values from the acute to the postconvalescent phases in 3 Shetland ponies with hyperlipemia in Japan. Diseased ponies (all 7 to 9 years old, in late pregnancy, and obese) were fed in the same farm. The periods of their hospitalizations ranged from 30 to 45 days. Twelve well-conditioned ponies (3 to 13 years old) around parturition were used to establish baseline values for blood test results. Main clinical findings in the affected ponies were depression, dysphagia, anorexia, ventral edema and milky-appearing plasma. Hypertriglyceridemia (40- to 70-fold rise of controls) was found in the acute phase of the disease in the affected ponies, and was derived from increased very-low density lipoproteins. Aspartate transaminase and gamma-glutamyl transpeptidase activities, blood urea nitrogen, and creatinin concentrations were increased in acute ponies compared to controls, suggesting impairment of liver and kidney functions. However, these values gradually recovered until the end of postconvalescent phase. Hyperinsulinemia was observed in the acute phase of the hyperlipemia of all affected ponies. And an exaggerated insulin response to intravenous glucose was observed in the 2 ponies given intravenous glucose tolerance tests. These findings suggest decreased insulin sensitivity in hyperlipemic ponies.

Insulin resistance is a characteristic feature of glucose intolerance in myotonic dystrophy type 1 (DM1). DM1 patients with dysglycaemia have liver insulin resistance as well as muscle insulin resistance, and also abnormality of insulin secretion. Insulin resistance in DM1 might result in multiple metabolic defects. Low level of fasting plasma glucose is a characteristic feature in the early stage of glucose intolerance in DM1, Early intervention against insulin resistance in DM1 is suggested because glucose intolerance could deteriorate in a certain degree of cases. Metformin treatment is useful to improve insulin resistance in DM1. Diabetic patients with DM1 usually show mild hyperglycemia. However, poorly controlled patients with hyperglycemic pattern tending to rise from morning to evening exist. Intensive insulin therapy might be necessary in such cases. We should pay attention to hypoglycemia due to hyperinsulinemia, pseudo improvement of glucose control according to exacerbated dysphagia, and acute aggravation caused by infections, at a bedside.
