[PMID: 38034512 PMCID: PMC10687782 DOI: 10.4322/acr.2023.451] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 09/05/2023] [Indexed: 12/02/2023]
Abstract
Non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS), without previous bariatric surgery, is a rare form of hypoglycemia in adult patients and is associated with nesidioblastosis. Adult-onset nesidioblastosis in diabetic patients is rare and histologically identical to "non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS)". Nesidioblastosis is rare in adults and clinically and biochemically mimics Insulinoma. In the literature, there have only been four cases of adult nesidioblastosis that followed diabetes mellitus. We report a case of nesidioblastosis in a 36-year-old diabetic female presenting with dizziness, sweating, and palpitations for three years. Selective non-invasive techniques failed to detect a tumor. Based on the pursuit of an insulinoma, a distal pancreatectomy specimen was received at our laboratory, and a diagnosis of nesidioblastosis was made. She is currently on follow-up with a favorable outcome. The definitive diagnosis of nesidioblastosis is made on a histological basis. The preferred form of treatment is pancreatic surgical resection. Nesidioblastosis should be taken into consideration in cases where diabetes transforms into hyperinsulinemic hypoglycemia.

An Uncommon Cause of Recurrent Presyncope, Dizziness, and Tachycardia: A Case Report of Diffuse, Adult-Onset Nesidioblastosis/Non-Insulinoma Pancreatogenous Hypoglycemia Syndrome (NIPHS). Biomedicines 2023; 11:1741.

Abstract
Neurovegetative and autonomic symptoms are common presentations of various diseases, ranging from psychosomatic to severe organic disorders. A 23-year-old man presented with a history of recurrent presyncope, dizziness, and tachycardia. Repeated diagnostic work-up in various clinical settings could not identify any definite cause for approximately eight years. However, the incidental detection of postprandial and exercise-induced hypoglycemia was suggestive of an insulin-related disorder. A 72 h plasma glucose fasting test revealed endogenous hyperinsulinism. Upon imaging studies, no tumor mass potentially indicating insulinoma could be detected. 68Ga-DOTA-Exendin-4 PET/CT showed diffuse tracer enrichment throughout the whole pancreas. A subtotal pancreatectomy was performed, and the diagnosis of diffuse, adult-onset nesidioblastosis was established histopathologically. This corresponds to the clinical findings of a functional β-cell disorder, also known as non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS). After nine months, the symptoms recurred, making complete pancreatectomy necessary. Postoperative laboratory evaluation exhibited no residual endogenous C-peptide production. This case illustrates the diagnostic challenges in patients presenting with unspecific, neurovegetative and autonomic symptoms with a severe and rare underlying cause.

Abstract
Differential diagnosis of hypoglycemia in the non-diabetic adult patient is complex and comprises various diseases, including endogenous hyperinsulinism caused by functional β-cell disorders. The latter is also designated as nesidioblastosis or non-insulinoma pancreatogenous hypoglycemia syndrome (NIPHS). Clinically, this rare disease presents with unspecific adrenergic and neuroglycopenic symptoms and is, therefore, often overlooked. A combination of careful clinical assessment, oral glucose tolerance testing, 72 h fasting, sectional and functional imaging, and invasive insulin measurements can lead to the correct diagnosis. Due to a lack of a pathophysiological understanding of the condition, conservative treatment options are limited and mostly ineffective. Therefore, nearly all patients currently undergo surgical resection of parts or the entire pancreas. Consequently, apart from faster diagnosis, more elaborate and less invasive treatment options are needed to relieve the patients from the dangerous and devastating symptoms. Based on a case of a 23-year-old man presenting with this disease in our department, we performed an extensive review of the medical literature dealing with this condition and herein presented a comprehensive discussion of this interesting disease, including all aspects from epidemiology to therapy.

Abstract
OBJECTIVES Pancreatic neuroendocrine microadenoma (NEMA) is a nonfunctioning neuroendocrine tumor of less than 5 mm. Most studies of NEMA were based on autopsies, and few reports have revealed the clinical frequency of NEMA. We investigated the clinicopathological features of NEMA. METHODS The pathological results of the pancreatic resection specimens of patients, older than 18 years, who underwent pancreatic resection at Hokkaido University Hospital between April 2008 and December 2020 were retrospectively reviewed. The NEMAs were re-examined in detail and examined by immunohistochemical staining. RESULTS Among 850 patients enrolled in this study, 24 NEMAs were identified in 12 patients (1.4%). Of the 12 patients, 2 patients had multiple endocrine neoplasia type 1, and the others had no hereditary disease, including 2 patients with multiple NEMAs. A difference in the number of NEMA was observed between patients with multiple endocrine neoplasia type 1 and sporadic NEMA. Intratumoral Ki-67 heterogeneity was correlated with the Ki-67 index. One grade 2 NEMA (Ki-67 index, 4.6%) was detected, but ATRX and DAXX labeling showed intact nuclear protein expression. CONCLUSIONS Multiple sporadic NEMAs and grade 2 NEMAs were observed, suggesting that NEMA may have malignant potential. Thus, NEMAs should be carefully monitored for lymph node metastasis and postoperative recurrence.

Abstract
BACKGROUND Noninsulinoma pancreatogenous hypoglycemia syndrome (NIPHS) is a rare syndrome characterized by postprandial hypoglycemia with neuroglycopenic symptoms occurring 1 to 3 h after a meal. Diagnosis can be elusive, as the vast majority of patients have normal fasting blood glucose levels, and onset of hypoglycemic episodes can be a late complication of gastric surgery. CASE REPORT We report the case of a 45-year-old woman presenting to the Emergency Department (ED) with new-onset seizures and hypoglycemia worsened by glucose administration. Surgical history is pertinent for a Roux-en-Y gastric bypass approximately 10 years prior to presentation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although rare, it is important for emergency physicians to be vigilant of this disease process as a traditional treatment approach for hypoglycemia may be detrimental. Although cases of NIPHS have been documented in literature, its presence in emergency medicine-specific literature is seemingly nonexistent. Noninvasive imaging techniques will be normal, and diagnosis is dependent on awareness of this disease entity coupled with a detailed history.

Abstract
Background Congenital hyperinsulinism (CH) is a rare disease, characterized by severe hypoglycemia induced by inappropriate insulin secretion from pancreatic beta-cells in neonate and infant. Hirschsprung’s disease (HD) is also a rare disease in which infants show severe bowel movement disorder. We herein report an extremely rare case of combined CH and HD. Case presentation The patient was a full-term male infant who showed poor feeding, vomiting, and hypotonia with lethargy on the day of birth. He was transferred to tertiary hospital after a laboratory analysis revealed hyperinsulinemic hypoglycemia. The patient showed remarkable abdominal distension without meconium defecation. An abdominal X-ray showed marked dilatation of the large bowel. He was diagnosed with CH (nesidioblastosis) associated with suspected HD. He was initially treated with an intravenous infusion of high-dose glucose with the intermittent injection of glucagon. This was successfully followed by treatment with diazoxide and octreotide (a somatostatin analog). At 8 months of age, HD was confirmed by the acetylcholinesterase staining of a rectal mucosal biopsy specimen, and a transanal pull-through operation was performed to treat HD. At 14 months of age, subtotal pancreatectomy was performed for the treatment of focal CH located in the pancreatic body. His postoperative course over the past 12 years has been uneventful without any neurologic or bowel movement disorders. Conclusions Although it is extremely rare for CH to be associated with HD, associated HD should be considered when a patient with CH presents severe constipation.

Abstract
AIM To present an insulinoma case with post-prandial hypoglycemic symptoms associated with glucose inducible endogenous hyperinsulinemia. CASE A 52-year-old female patient was evaluated for hypoglycemic symptoms especially those occuring within 3 hours after consuming sugary foods. These symptoms were persistent for a year and a half. She was diagnosed with reactive (post-prandial) syndrome and followed a recommended diet and was given acarbose but there was no improvement. The results suggested post-prandial endogenous hyperinsulinemia related hypoglycemia. Multiphasic computerized tomography revealed an 11x15x12 mm size mass lesion, anteriorly in the head and uncinate process of the pancreas and then the patients were treated surgically with pancreatic enucleation and cured. CONCLUSION Distinguishing post-prandial syndrome by careful history and clinical evaluation in patients with postprandial symptoms is of great importance in terms of cost-effectivity. However, it should not be forgotten that although organic pathologies are mostly presented with fasting hypoglycemia, they may also cause post-prandial symptoms. Severity and progression of the symptoms that point to neuroglycopenia is important, and in this condition the most convenient clinical approach to the patient should be performed with careful and appropriate assessment steps.

Abstract
Infants born to diabetic mothers are at increased risk for symptomatic hypoglycemia and death after birth. A 36-year-old G4P3 mother with a history of gestational diabetes and newly diagnosed type II insulin-dependent diabetes gave birth at home, in the care of a midwife, to a macrosomic infant girl (10 lbs.). Several hours after birth, the infant became lethargic and was found to be hypoglycemic (blood sugar: 28 mg/dL). Glucose and sugar water were administered by the midwife; however, the infant continued to decompensate. Emergency medical services were called, and the infant was transported to the hospital where, despite resuscitative efforts, she died. An autopsy and review of the literature was performed. At autopsy, characteristic features of maternal-fetal glucose dysregulation were identified, including fetal macrosomia, cardiomegaly, hepatomegaly, and severe pancreatic islet cell hypertrophy/hyperplasia. Developmental abnormalities and other potential causes of death were not identified. Although deaths due to hypoglycemia cannot be reliably diagnosed postmortem using vitreous glucose levels, a clinical history of maternal glucose dysregulation in combination with certain gross and histologic findings should prompt a pathologist to consider maternal-fetal glucose dysregulation as a diagnosis of exclusion and cause of death.

Abstract
Innovation can be variably defined, but when applied to healthcare is often considered to be the introduction of something new, whether an idea, method or device, into an unfilled void or needy environment. Despite the introduction of many positive surgical subspecialty altering concepts/devices however, epic failures are not uncommon. These failures can be dramatic in regards to both their human and economic costs. They can also be very public or more quiet in nature. As surgical leaders in our communities and advocates for patient safety and outcomes, it remains crucial that we meet new introductions in technology and patient care with a measured level of curiosity, skepticism and science-based conclusions. The aim of an expert committee was to identify the most dominant failures in technological innovation and/or dogmatic clinical beliefs within each major surgical subspecialty. In summary, this effort was pursued to highlight the past failures and remind surgeons to remain vigilant and appropriately skeptical with regard to the introduction of new innovations and clinical beliefs within our craft.

Abstract
Case summary A 6-year-old, neutered female British Shorthair cat presented with acute-onset weakness and mental dullness. Initially the cat was mildly hyperglycaemic (9.9 mmol/l; reference interval [RI] 3.3-6.7 mmol/l). Over the following 12 h the cat developed central blindness, tremors, intermittent seizures and opisthotonus. Repeat blood sampling revealed a marked hypoglycaemia (0.8 mmol/l). Insulin level (performed on a serum sample collected while the cat was hypoglycaemic) was inappropriately elevated (1575 mIU/l; RI 10-80 mIU/l). An abdominal ultrasound was unremarkable. An exploratory laparotomy revealed a firm and erythematous left limb of the pancreas. Following surgical resection of the left limb of the pancreas, the cat returned to a euglycaemic state after a brief rebound hyperglycaemia. Histopathology revealed pancreatic fibrosis with marked multifocal micronodular hyperplasia of exocrine and endocrine cells. Synaptophysin immunohistochemistry confirmed nodular β-cell hyperplasia. Relevance and novel information Nesidioblastosis describes a syndrome of acquired hyperinsulinaemia and associated hypoglycaemia secondary to focal or diffuse (non-neoplastic) β-cell hyperplasia within the pancreas. Acquired nesidioblastosis has been reported in humans, where β-cell dysregulation is thought to occur in response to pancreatic injury. This is the first reported case of clinically significant hypoglycaemia due to acquired nesidioblastosis in an adult domestic cat. While this condition is rare, nesidioblastosis is being increasingly recognised in humans and it is an important differential diagnosis to consider when investigating hypoglycaemia as it cannot be distinguished from insulinoma without histopathological evaluation. While recurrence has been occasionally reported in humans, the prognosis is considered good.

Synchronous Nesidioblastosis, Endocrine Microadenoma, and Intraductal Papillary Mucinous Neoplasia in a Man Presenting With Hyperinsulinemic Hypoglycemia. Pancreas 2016; 45:154-9.

Abstract
Herein, we report the first case of concomitant nesidioblastosis, pancreatic neuroendocrine tumor, and intraductal papillary mucinous neoplasia. The combination is significant as each of these pathological entities is independently very rare. The patient was a 33-year-old man who presented with symptomatic hyperinsulinemic hypoglycemia and no risk factors for pancreatic disease. Abdominal imaging showed an isolated 12 mm pancreatic lesion, whilst selective arterial calcium stimulation testing demonstrated multiple territories of insulin excess. He proceeded to subtotal pancreatectomy. Histopathology revealed an endocrine microadenoma, α and β cell nesidioblastosis, and multifocal intraductal papillary mucinous neoplasia. The endocrine microadenoma and nesidioblastosis stained for insulin, suggesting both likely contributed to hypoglycemia. Glucagon immunohistochemistry was also positive, though there were no clinical features of glucagon excess. Hypoglycemia resolved postoperatively. This case and other evidence from the literature suggest that hyperplasia and neoplasia may occur sequentially in the pancreas, and that endocrine and exocrine tumorigenesis may be linked in some individuals. Further study is required to identify a unifying mechanism, and to elucidate potential ramifications in the management of patients with pancreatic neoplasms.

Abstract
Nesidioblastosis is a major cause of persistent hyperinsulinemic hypoglycemia of infancy and is caused by hypertrophy of the pancreatic endocrine islands. The disease can be categorized histologically into diffuse and focal forms. The condition rarely occurs in adults and only one adult case of suspected, but not histologically confirmed, focal nesidioblastosis has been reported. The present study describes the case of a 62-year-old man suffering from symptomatic hypoglycemia for 3 years and exhibiting a nodule in the pancreatic tail. Pathological evaluation following surgical enucleation of the pancreatic body and tail revealed focal nesidioblastosis. The hypoglycemic symptoms of the patient disappeared postoperatively. To the best of our knowledge, this is the first histologically-confirmed case of focal adult nesidioblastosis, suggesting that the possibility of nesidioblastosis should be taken into account in adult patients with persistent hypoglycemia.

Abstract
One of the key promises of regenerative medicine is providing a cure for diabetes. Cell-based therapies are proving their safety and efficiency, but donor beta cell shortages and immunological issues remain major hurdles. Reprogramming of human pancreatic exocrine cells towards beta cells would offer a major advantage by providing an abundant and autologous source of beta cells. Over the past decade our understanding of transdifferentiation processes greatly increased allowing us to design reprogramming protocols that fairly aim for clinical trials.

Abstract
The autosomal recessive form of persistent hyperinsulinemic hypoglycemia of infancy (PHHI) is associated with mutations in either ABCC8 or KCNJ11 genes. In the present study, we describe the clinical features and results of genetic analysis of 13 Saudi Arabian patients with PHHI. Clinically, most patients presented with infantile seizures and/or developmental delay, with a subset of patients who were also found to have abnormal brain imaging and electrophysiological studies. Interestingly no coding pathogenic mutations were identified in these two genes by direct sequencing. However, two splice variants were identified in ABCC8 gene in two patients, and a large deletion of exons 1-22 of the ABCC8 gene was identified in three patients. Our data shows that large deletions in ABCC8 gene are the common genetic mechanism in the Saudi population.

Abstract
BACKGROUND Endogenous hyperinsulinemic hypoglycemia (EHH) is characterized by an inappropriately high plasma insulin level, despite a low plasma glucose level. Most of the EHH cases are caused by insulinoma, whereas nesidioblastosis and insulin autoimmune syndrome (IAS) are relatively rare. METHODS To evaluate the relative frequencies of various causes of EHH in Korea, we retrospectively analyzed 84 patients who were diagnosed with EHH from 1998 to 2012 in a university hospital. RESULTS Among the 84 EHH patients, 74 patients (88%), five (6%), and five (6%) were diagnosed with insulinoma, nesidioblastosis or IAS, respectively. The most common clinical manifestation of EHH was neuroglycopenic symptoms. Symptom duration before diagnosis was 14.5 months (range, 1 to 120 months) for insulinoma, 1.0 months (range, 6 days to 7 months) for nesidioblastosis, and 2.0 months (range, 1 to 12 months) for IAS. One patient, who was diagnosed with nesidioblastosis in 2006, underwent distal pancreatectomy but was later determined to be positive for insulin autoantibodies. Except for one patient who was diagnosed in 2007, the remaining three patients with nesidioblastosis demonstrated severe hyperinsulinemia (157 to 2,719 µIU/mL), which suggests that these patients might have had IAS, rather than nesidioblastosis. CONCLUSION The results of this study suggest that the prevalence of IAS may be higher in Korea than previously thought. Therefore, measurement of insulin autoantibody levels is warranted for EHH patients, especially in patients with very high plasma insulin levels.

Abstract
PURPOSE Rare endocrine-metabolic diseases (REMD) represent an important area in the field of medicine and pharmacology. The rare diseases of interest to endocrinologists involve all fields of endocrinology, including rare diseases of the pituitary, thyroid and adrenal glands, paraganglia, ovary and testis, disorders of bone and mineral metabolism, energy and lipid metabolism, water metabolism, and syndromes with possible involvement of multiple endocrine glands, and neuroendocrine tumors. Taking advantage of the constitution of a study group on REMD within the Italian Society of Endocrinology, consisting of basic and clinical scientists, a document on the taxonomy of REMD has been produced. METHODS AND RESULTS This document has been designed to include mainly REMD manifesting or persisting into adulthood. The taxonomy of REMD of the adult comprises a total of 166 main disorders, 338 including all variants and subtypes, described into 11 tables. CONCLUSIONS This report provides a complete taxonomy to classify REMD of the adult. In the future, the creation of registries of rare endocrine diseases to collect data on cohorts of patients and the development of common and standardized diagnostic and therapeutic pathways for each rare endocrine disease is advisable. This will help planning and performing intervention studies in larger groups of patients to prove the efficacy, effectiveness, and safety of a specific treatment.

Abstract
Here, we present the case of a 31-year-old woman patient who underwent distal pancreatectomy with the history of gastric bypass surgery for obesity. The final histopathological diagnosis of the lesion was nesidioblastosis. Nesidioblastosis is the most common cause of organic persistent hyperinsulinemic hypoglycemia in newborns; however, it is rare in adults. In adults, it is difficult to diagnose nesidioblastosis with only clinical findings. The definitive diagnosis of the disease depends on the histopathological examination of pancreatic tissue and the exclusion of insulinoma.

Abstract
INTRODUCTION Nesidioblastosis (NB) is rare disease with organic hyperinsulinism syndrome and caused by diffuse hyperplasia and/or hypertrophy of pancreatic islands of Langerhans. MATERIAL AND METHODS The results of surgical treatment of 3 patients with NB are presented. In all patients the diagnosis was suspected at the preoperative stage and confirmed by histological examination later. Herewith in 2 patients NB was combined with insulinoma. All patients underwent corpora-caudal pancreatectomy. RESULTS In postoperative period one patient hadn't episodes of hypoglycemia for the entire follow-up period (5 months), in another patient hypoglycemic states occurred at 1.5 months after surgery. The third patient required pancreatic head extirpation at 11 days after surgery due to persistent severe course of organic hyperinsulinism. In immediate postoperative period in the same patient hyperinsular hypoglycemia was observed that pointed on extrapancreatic source of insulin secretion. However contrast-enhanced CT did not reveal any formations. CONCLUSION Thus, corpora-caudal pancreatectomy is preferable as surgical treatment. Results of surgical management can provide a complete regression of the symptoms, but do not guarantee absence of recurrence and even any changes in frequency and severity of hypoglycemic states.

Abstract
Diabetes mellitus, which may cause hyperglycemia and a number of complications, mostly results from a deficiency of β cell mass (type 1 diabetes) or a limitation of β cell function (type 2 diabetes). Currently, enhancing β cell regeneration and increasing cell proliferation have not only been described in experimental diabetes models, but have also been proven to improve outcomes for patients with diabetes. Therefore, understanding the mechanisms controlling the development and regeneration of β cells in the human pancreas may be helpful for the treatment of β cell-deficient disease. In this review, we first introduce the various cell types in the adult pancreas and thereby clarify their functions and origins. Then, the known mechanisms of β cell development and expansion in the normal human pancreas are described. The potential mechanisms of β cell regeneration, including β cell self-replication, neogenesis from non-β cell precursors and transdifferentiation from α cells, are discussed in the next part. Finally, the ability of the pancreas to regenerate mature β cells is explored in pathological conditions, including type 1 diabetes, chronic pancreatitis and persistent hyperinsulinemic hypoglycemia of infancy.

Abstract
Congenital hyperinsulinism (HI) is characterized by profound hypoglycemia caused by inappropriate insulin secretion. HI is a heterogeneous disorder with at least two histologic lesions and several implicated genes. If HI is caused by a focal lesion, elective surgery is the treatment of choice because it leads to complete recovery without diabetes. On the contrary, near-total pancreatectomy though recommended for diffuse HI, long-term risks of endocrine and exocrine deficiencies are present. Between the years 2006-2011, three patients of HI were referred to and operated by a single surgeon. The preoperative diagnosis was confirmed by recurrent hypoglycemia, inappropriately high insulin levels, and augmented glucose requirements. The medical records of all three patients were reviewed to study their clinical features, medical and surgical treatment, and postoperative outcome (short- and long-term). There were three patients in this series (male/female ratio, 1:2), all presenting in the neonatal age. All patients failed medical treatment, and radiological imaging did not reveal any pancreatic lesion. All patients underwent subtotal (80 %) pancreatectomy. Two patients had diffuse type of HI and one focal HI. One patient had transient hyperglycemia for 3 months, which needed insulin supplementation. No patient has developed recurrent hypoglycemia, malabsorption syndrome, or any neurological sequelae until the last follow-up. Doing subtotal or near-total pancreatectomy in diffuse type of HI still remains controversial as one has a higher risk of recurrent hypoglycemia, while the other has a higher rate of insulin dependent diabetes mellitus. Subtotal (80 %) pancreatectomy may be considered as the primary modality of surgical intervention in diffuse type of HI, especially when the diagnostic facilities are limited or diagnosis is not known after preliminary investigations. This minimizes the chances of postoperative diabetes mellitus, and redo surgery can always be considered if there is recurrent hypoglycemia.

Abstract
Endocrine cells are evident at an early stage in bovine pancreatic development when the pancreas still consists of primitive epithelial cords. At this stage, the endocrine cells are interspersed between the precursor cells destined to form the ductulo-acinar trees of later exocrine lobules. We here demonstrate that, in bovine fetuses of crown rump length ≥ 11 cm, the endocrine cells become increasingly segregated from the developing exocrine pancreas by assembly into two units that differ in histogenesis, architecture, and fate. Small numbers of 'perilobular giant islets' are distinguishable from larger numbers of 'intralobular small islets'. The two types of islets arise in parallel from the ends of the ductal tree. Aside from differences in number, location, and size, the giant and small islets differ in cellular composition (predominantly insulin-synthesising cells vs. mixtures of endocrine cells), morphology (epithelial trabeculae with gyriform and rosette-like appearance vs. compact circular arrangements of endocrine cells), and in their relationships to intrapancreatic ganglia and nerves. A further difference becomes apparent during the antenatal period; while the 'interlobular small islets' persist in the pancreata of calves and adult cattle, the perilobular giant islets are subject to regression, characterised by involution of the parenchyma, extensive haemorrhage, leukocyte infiltration (myeloid and T-cells) and progressive fibrotic replacement. In conclusion, epithelial precursor cells of the ductolo-acinar tree may give rise to populations of pancreatic islets with different histomorphology, cellular composition and fates. This should be taken into account when using these cells for the generation of pancreatic islets for transplantation therapy.

Abstract
INTRODUCTION Hyperinsulinemic hypoglycemia with severe neuroglycopenia has been identified as a late complication of Roux-en-Y gastric bypass (RYGB) in a small number of patients. DISCUSSION The rapid resolution of type 2 diabetes mellitus after RYGB is probably related to increased secretion of the incretin hormones glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), and patients with post-RYGB hypoglycemia demonstrate prolonged elevations of GIP and GLP-1 compared to non-hypoglycemic post-RYGB patients. Nesidioblastosis has been identified in some patients with post-RYGB hypoglycemia and is likely due to the trophic effects of GIP and GLP-1 on pancreatic islets. CONCLUSIONS Treatment of hypoglycemia after RYGB should begin with strict dietary (low carbohydrate) alteration and may require a trial of diazoxide, octreotide, or calcium-channel antagonists, among other drugs. Surgical therapy should include consideration of a restrictive form of bariatric procedure, with or without reconstitution of gastrointestinal continuity. Partial or total pancreatic resection should be avoided.

Abstract
The global prevalence of type 2 diabetes mellitus and impaired glucose metabolism continues to rise in conjunction with the pandemic of obesity. The metabolic Roux-en-Y gastric bypass operation offers the successful resolution of diabetes in addition to sustained weight loss and excellent long-term outcomes in morbidly obese individuals. The procedure consists of the physiological BRAVE effects: (i) Bile flow alteration; (ii) Reduction of gastric size; (iii) Anatomical gut rearrangement and altered flow of nutrients; (iv) Vagal manipulation and (v) Enteric gut hormone modulation. This operation provides anti-diabetic effects through decreasing insulin resistance and increasing the efficiency of insulin secretion. These metabolic outcomes are achieved through weight-independent and weight-dependent mechanisms. These include the foregut, midgut and hindgut mechanisms, decreased inflammation, fat, adipokine and bile metabolism, metabolic modulation, shifts in gut microbial composition and intestinal gluconeogenesis. In a small minority of patients, gastric bypass results in hyperinsulinaemic hypoglycaemia that may lead to nesidioblastosis (pancreatic beta-cell hypertrophy with islet hyperplasia). Elucidating the precise metabolic mechanisms of diabetes resolution and hyperinsulinaemia after surgery can lead to improved operations and disease-specific procedures including 'diabetes surgery'. It can also improve our understanding of diabetes pathogenesis that may provide novel strategies for the management of metabolic syndrome and impaired glucose metabolism.

Abstract
The issue of beta cell regeneration in human pancreas is probably one of the most controversial aspects of type 1 diabetes research. In this review, we will first describe the known mechanisms underlying beta cell development and expansion in normal human pancreatic development because it is likely that such mechanisms might also play a role in beta cell regeneration. The sensu strictiori definition of beta cells implies replacement of lost beta cell mass by new beta cells. In our discussion, however, we will use the term in a more general way, defining as regeneration the formation of new beta cells, whether or not a loss of beta cells has actually occurred. The potential mechanisms of beta cell regeneration in the human pancreas will be discussed in the second part of this review. In particular, we will analyze beta cell regeneration through proliferation of beta cells, neogenesis from non-beta cell precursors, and transdifferentiation from alpha cells. In the third part of this review, we will explore the arguments for and against the ability of the human pancreas to regenerate functional beta cells in the context of type 1 diabetes and in other pathological conditions.

Abstract
Introduction Non-insulinoma pancreatogenous hypoglycemic syndrome is a rare disorder among adults, and, to our knowledge, only about 40 cases have been reported in the literature. Case presentation The patient is a previously healthy 35-year-old Caucasian man. His symptoms began four years ago when he suddenly felt weakness in his legs and started sweating for unknown reasons. The symptoms worsened, and laboratory tests revealed hypoglycemia and hyperinsulinemia at the time of the symptoms. All diagnostics attempts using magnetic resonance imaging, computed tomography, and endoscopic ultrasound did not reveal any abnormalities. At this stage, surgical intervention was planned, and a distal 80% pancreatectomy was performed. The histopathologic and immunohistochemical investigations of the pancreas showed an increased number of islets of different sizes, more or less evenly distributed in the gland, but no insulinoma. Patch-clamp recordings from isolated pancreatic β-cells showed that, even at a low glucose concentration (3 mmol/L), the β-cell membrane was depolarized, and action potentials were seen. Surprisingly, in patch-clamp experiments, the addition of diazoxide had a marked effect on K-ATP channel activity and membrane potential, but no effect on insulin levels in vivo before surgery. Conclusion This case report adds new information on the pathogenesis of non-insulinoma pancreatogenous hypoglycemic syndrome, as we performed an electrophysiologic characterization of isolated islet cells. We show, for the first time, that β-cells isolated from a non-insulinoma pancreatogenous hypoglycemic syndrome patient are constantly depolarized, even at low glucose levels, but display normal K-ATP channel physiology.

Abstract
OBJECTIVE To describe the successful treatment of severe noninsulinoma hyperinsulinemic hypoglycemia with use of a calcium channel blocking agent in an adult patient who had previously undergone a gastric bypass surgical procedure. METHODS A 65-year-old woman who had undergone a gastric bypass surgical procedure 26 years earlier was hospitalized because of severe postprandial hypoglycemia. During and after hospitalization, the patient underwent assessment with conventional measurements of glucose, insulin, proinsulin, and C-peptide; toxicologic studies; magnetic resonance imaging studies of the pancreas; and determination of hepatic vein insulin concentrations after selective splanchnic artery calcium infusion. RESULTS Metabolic variables were consistent with the diagnosis of hyperinsulinemic hypoglycemia. Magnetic resonance imaging revealed the presence of a side branch intraductal papillary mucinous tumor that had been stable for more than 1 year. The results of the calcium-stimulated insulin release study were consistent with nonlocalized hypersecretion of insulin. A trial of frequent small feedings failed to prevent hypoglycemia. On the basis of reports of successful treatment of childhood nesidioblastosis, the patient was then prescribed nifedipine, 30 mg daily. She has subsequently remained free of symptomatic hypoglycemia for 20 months. CONCLUSION A calcium channel blocking agent may be efficacious and a potential alternative to partial pancreatectomy in cases of noninsulinoma hyperinsulinemic hypoglycemia in adults.

Abstract
Hypoglycemia secondary to nesidioblastosis is rare in adults, and the pathogenesis of this condition is unknown. To determine factors leading to nesidioblastosis in adults, we analyzed 36 cases of nesidioblastosis including 27 cases of postgastric bypass nesidioblastosis and 9 cases of idiopathic nesidioblastosis in adults by immunohistochemistry using antibodies to insulin-like growth factor 1, insulin-like growth factor 2 (IGF2), insulin-like growth factor one receptor-alpha epidermal growth factor receptor, transforming growth factor-beta1 and 2, and transforming growth factor-beta receptor type 3. Fifty-two surgically excised pancreatic specimens from patients with benign exocrine tumors and no evidence of hypoglycemia were used as controls. There was increased IGF2, insulin-like growth factor receptor 1 receptor-alpha and transforming growth factor-beta receptor 3 expression in islets from nesidioblastosis patients compared to controls. Peliosis-type vascular ectasia was more common in nesidioblastosis patients compared to controls. These findings suggest that increased production of growth factors and growth factor receptors may contribute to the development of nesidioblastosis in adults.

Abstract
UNLABELLED Persistent hyperinsulinemic hypoglycemia (nesidioblastosis) not caused by an insulinoma is rare in adults. Morphologically no insulin secreting tumor is present. Keystones of diagnosis are not only low glucose levels but to maintain normoglycemia by use of intravenous glucose and the presence of high insulin and C-peptide levels. Noninvasive and invasive diagnostic techniques are required to rule out a hormone secreting tumor. Both conservative and/or surgical therapy are suggested to prevent damaging effects of repeated hypoglycemia. CASE REPORT Two patients with frequent and serious episodes of hypoglycemia are reported. In the 34-year-old female symptoms appeared with sweating, dizziness, trembling, nervousness and serious neuroglycopenic signs. In the 22-year-old male the main complaint was tympany, a rare and unusual sign of hypoglycemia, and intense feeling of esurience. The 24-hour fasting test was positive in both cases, i.e. it had to be stopped because of symptomatic hypoglycemia. No insulinoma could be localized, despite extensive search, therefore in both cases the diagnosis of adult-onset nesidioblastosis was set up, despite lack of histological confirmation. Diazoxide therapy resulted in symptom-free life for both patients. CONCLUSION Several diagnostic methods and treatment options are suggested for the rare disease nesidioblastosis to balance defective insulin secretion. However, once the decision is made in favour of surgical therapy, there is a thin line between successful treatment, persistence of the disease, and pancreatic insufficiency. Therefore it is worth considering to try conservative therapy especially when surgery is of high risk. Our cases suggest that diazoxide therapy is an effective and safe alternative in the treatment of adult-onset nesidioblastosis.

Abstract
Introduction Hyperinsulinism is the most common cause of recurrent and persistent hypoglycemia in infancy and childhood. Causes can include nesidioblastosis, pancreatic islet cell tumors such as insulinoma, and associations with multiple endocrine neoplasia syndromes. Although new, improved imaging techniques have allowed for more precise preoperative localization of insulinomas, the differentiation of nesidioblastosis and insulinoma, particularly in children, can be challenging. To improve intraoperative localization and confirmation of successful resection of insulinoma, a novel hormonal assay, the rapid intraoperative insulin assay, is reported for the first time in a pediatric patient. This intraoperative radioimmunoassay for insulin yields results within several minutes and confirms complete resection of insulinoma. Case description We present a case of pancreatic insulinoma in a child with symptoms of severe hypoglycemia, causing seizures. The insulinoma was enucleated laparoscopically, and rapid intra-operative insulin assay used to determine the success of the procedure. Discussion and evaluation This rapid intra-operative test provides a valuable adjunct for determining complete excision in complicated cases of recurrent or questionable insulinoma. Although not a common problem, for pediatric patients in whom the diagnosis is not clear, this test may provide a novel approach to confirming disease. Conclusion We propose the use of this assay in facilitating intra-operative resection and confirmation of complete excision in pediatric patients. This population may especially benefit from this novel assay to confirm complete resection and to differentiate multiple etiologies of hyperinsulinism.

Abstract
Congenital Hyperinsulinism of Infancy (CHI) is a genetically heterogeneous disorder characterized by profound hypoglycemia related to inappropriate insulin secretion. Two histopathologically and genetically distinct groups are recognized among patients with CHI due to ATP-sensitive potassium channel (KATP) defects: a diffuse type (Di-CHI), which involves the whole pancreas, and a focal form (Fo-CHI), which shows adenomatous islet-cell hyperplasia of a particular area within the normal pancreas. The beta-cell KATP channel consists of two essential subunits: Kir6.2 encoded by the KCNJ11 gene which is the pore-forming unit and belongs to the inwardly rectifying potassium channel family, and SUR1 (sulfonylurea receptor 1) encoded by the ABCC8 gene, which belongs to the ATP-binding cassette (ABC) transporter family. The KATP channel is an octameric complex of four Kir6.2 and four SUR1 subunits. More than one hundred mutations have been found in KATP channel genes ABCC8 and KCNJ11, but to date only twenty mutations have been identified in KCNJ11, most of them are missense mutations and only one is a single base deletion. The Fo-CHI has been demonstrated to arise in individuals who have a germline mutation in the paternal allele of ABCC8 or KCNJ11 in addition to a somatic loss of the maternally derived chromosome region 11p15 in adenomatous pancreatic beta-cells, while Di-CHI predominantly arises from the autosomal recessive inheritance of KATP channel gene mutations. Here we describe the molecular findings in nine children who presented, in the neonatal period, with signs and symptoms of hypoglycemia and diagnosed affected by CHI according to international diagnostic criteria. Direct sequencing of the complete coding exon and promoter region of KCNJ11 gene showed, in two Italian patients, two new heterozygous mutations which result in the appearance of premature translation termination codons resulting in the premature end of Kir6.2. Interestingly most of the CHI mutations detected in other population studies are situated in the ABCC8 gene.

Abstract
Persistent Hyperinsulinemic Endogenous hypoglycemia in adults is, in most cases, due to Insulinoma. Nesidioblastosis, a peculiar functional hyperinsulinemia from hypertrophic beta cells, has been described mainly in newborns. This article describes a 34-year-old patient who presented hyperinsulinemic endogenous hypoglycemia clinical and laboratorial situation (Fasting glycemia: 54 mg/dl / Reference Interval (RI): 60-99 mg/dl; Serum insulin: 70.9 mcU/ml / RI: < 29.1 mcU/ml; e C peptide: 7.1 ng/ml / RI: 1.1-5.0 ng/ml). It was suspected Insulinoma. Because of the lack of typical images in radiologic exams (ultrasonography and computerized tomography) it had been decided to do laparotomy, but it was not found any macroscopic pancreatic tumor. Histological and histochemistry examination of a distal pancreatic segment showed alteration suitable to nesidioblastosis. The patient presented clinical stability during the next two months, however, after that, there was a recurrence of a hypoglycemia crisis, refractory to Octreotide administration. It was done "octreoscan", which showed expanded nesidioblastosis, being done extensive partial pancreatectomy. Octreotide was used again, with a good control of the hypoglycemia crisis. As it is an uncommon diagnosis in an adult, the objective of this article is to describe the diagnostic and therapeutic aspects in cases of hyperinsulinemic endogenous hypoglicemia.

Abstract
sonic hedgehog (shh) is expressed in anterior endoderm, where it is required to repress pancreas gene expression and to pattern the endoderm, but the pathway controlling endodermal shh expression is unclear. We find that expression of meis3, a TALE class homeodomain gene, coincides with shh expression in the endoderm of zebrafish embryos. Using a dominant negative construct or anti-sense morpholino oligos (MOs) to disrupt meis3 function, we observe ectopic insulin expression in anterior endoderm. This phenotype is also observed when meis3 MOs are targeted to the endoderm, suggesting that meis3 acts within the endoderm to restrict insulin expression. We also find that meis3 is required for endodermal shh expression, indicating that meis3 acts upstream of shh to restrict insulin expression. Loss of pbx4, a TALE gene encoding a Meis cofactor, produces the same phenotype as loss of meis3, consistent with Meis3 acting in a complex with Pbx4 as reported in other systems. Lastly, we observe a progressive anterior displacement of endoderm-derived organs upon disruption of meis3 or pbx4, apparently as a result of underdevelopment of the pharyngeal region. Our data indicate that meis3 and pbx4 regulate shh expression in anterior endoderm, thereby influencing patterning and growth of the foregut.
