(1991) commented that multiple cases of adenoma had not been reported in sibships. None of these patients had additional histologic abnormalities. Four of the simplex cases had an adenoma all were cured by its removal. Differing histologic findings were found in 3 infants in 1 family and 2 in another family both within and among multiplex families, there was no consistency of the histologic change. Pancreatic histologic data were available for 22 of the 25 patients who underwent pancreatectomy. The segregation ratio, 0.254, agreed closely with that expected for an autosomal recessive disorder. There were no consistent clinical, biochemical, or histologic differences between patients in the 5 multiplex and 21 simplex families. (1991) found that 5 had more than 1 affected child (19%). Of 26 families seen over a period of 15 years, Thornton et al. Segregation analysis showed that the ratio of subsequent affected to unaffected sibs was similar to that expected of an autosomal recessive condition. (1991) found consanguineous parentage in 5 of 28 families. Consanguinity was evident in the Bedouin and Arab families. (1990) reported a total of 21 cases in 7 pedigrees, which included a large Bedouin family, an Arab family, and 5 Jewish families of Eastern European origin (Ashkenazi). In addition, a brother and sister who died in the neonatal period were probably affected. (1989) described the disorder in a brother and sister whose parents were consanguineous. Four of the group I patients had the Beckwith EMG syndrome ( 130650). Group II patients ranged in age from 3 to 15 years. Group I patients were 8 months old or younger. (1980) recognized 2 histologic groups of nesidioblastosis among cases of hyperinsulinemic hypoglycemia: group I had diffuse hyperplasia of the islets of Langerhans as well as nesidioblastosis group II had more subtle nesidioblastosis alone. The disorder presented as severe neonatal hypoglycemia. (1979) observed the disorder in 5 children of both sexes from 2 families with unaffected parents.

(1971) was first to report nesidioblastosis in a series of infants with intractable hypoglycemia. 'Nesidio' comes from a Greek word for islet. The term nesidioblastosis (meaning neoformation of islets of Langerhans from pancreatic duct epithelium) was coined by Laidlaw (1938) to describe the diffuse abnormality of the pancreas in which there is extensive, often disorganized formation of new islets. There is evidence of further genetic heterogeneity of HHF. HHF7 ( 610021) is caused by mutation in the SLC16A1 ( 600682) on chromosome 1p13. HHF6 ( 606762) is caused by mutation in the GLUD1 gene ( 138130) on chromosome 10q23. HHF5 ( 609968) is caused by mutation in the insulin receptor gene (INSR 147670) on chromosome 19p13. HHF4 ( 609975) is caused by mutation in the HADH gene ( 601609) on chromosome 4q25. HHF3 ( 602485) is caused by mutation in the glucokinase gene (GCK 138079) on chromosome 7p13.
HHF2 ( 601820) is caused by mutation in the KCNJ11 gene ( 600937) on chromosome 11p15. Genetic Heterogeneity of Hyperinsulinemic Hypoglycemia Unless early and aggressive intervention is undertaken, brain damage from recurrent episodes of hypoglycemia may occur ( Thornton et al., 1998). Anything more and I will go nuts.Didn't mention laundry, cooking, grocery shopping, errands/bills etc.Familial hyperinsulinism, also referred to as congenital hyperinsulinism, nesidioblastosis, or persistent hyperinsulinemic hypoglycemia of infancy (PPHI), is the most common cause of persistent hypoglycemia in infancy and is due to defective negative feedback regulation of insulin secretion by low glucose levels. I do work part-time and fit it around my schedule. Sun: Study, relax and spend some time with spouse Wed: Study, prepare for clinical drive to facility and pick up pt. I am one to say.try it out and find out for yourself and don't take my opinion but have a back up plan. Not to mention anytime left for you to relax. There is 1 person that I know of in my program who does this (has no other choice) and the side effects are creeping behind her. Yes, you might be able to handle it but surely without getting burnt out or neglecting your sleep/health IMHO. I would have to base my advice on experience.
