Fibrocalcific pancreatic diabetes (FCPD) is a rare form of diabetes affecting people in the tropics and presenting with unique clinical and radiological features. The onset of diabetes usually follows the first few episodes of abdominal pain and develops by the second or third decade of life. Endocrine and exocrine pancreatic insufficiency, brittle glycemic control, and insulin-requiring, ketosis-resistant diabetes are the novel characteristics of FCPD. The etiopathogenetic mechanisms leading to FCPD remain unknown. Although defects in insulin secretion are the major contributors, growing evidence towards a possible role for insulin resistance and body composition abnormalities have added a new dimension to the disease pathogenesis. Deciphering the key pathogenetic mechanisms may have a profound effect on therapeutic strategies in future studies on FCPD.

Chronic pancreatitis is a complex disease both for the epidemiology, with uncertain data on the exact prevalence, but also for the etiology, often not identified and for whom, compared to the past, post acute pancreatitis forms are showing a high impact; also smoking is an etiological factor often underestimated compared to alcohol. Chronic pancreatitis is associated with high mortality and morbidity, mostly due to extrapancreatic diseases. The eventual occurrence of exocrine or endocrine pancreatic insufficiency can lead to complications, often serious and not prevented in time. It is, in fact, well known how this can cause micro or macronutrient and vitamin deficit which, if not screened and corrected, can cause complications such as osteoporosis. Abdominal pain is the most relevant symptom, with a complex pathogenesis, due not only to obstructive or mechanical factors or inflammation, but also to a chronic alteration of the adaptation process of pain in the central nervous system. Also for this reason, therapies are often not effective. Derivative surgery is indicated in obstructive forms, with results superior to those of endoscopy, while resective surgery is indicated when an inflammatory mass is present. A new opportunity is total pancreatectomy with islet autotransplantation, which offers excellent results in terms of pain relief and possibility to avoid diabetes in a high percentage of patients. This review will discuss these hot topics comprehending both most recent evidence and a view on how our knowledge on this disease will change in the upcoming years.

There are very few reports of elevated lipase in pediatric inflammatory bowel disease (IBD). Symptoms of pancreatitis may be masked by abdominal pain in pediatric IBD. During the initial presentation of IBD in our patient, lipase was elevated to more than 3 times the upper limit of normal. Normalization of values coincided with remission of IBD. This may be due to extraintestinal involvement of the pancreas as part of the inflammatory process or due to leakage of pancreatic enzymes from an inflamed gut or mediated by inflammatory cytokines. Checking pancreatic enzymes during initial presentation of IBD may, therefore, be important to determine if pancreatic involvement has resulted from the inflammation in IBD or as an adverse effect of therapy. If unchecked, recurrent subclinical pancreatitis may be masked by IBD symptoms and missed prior to starting IBD therapy. This may result in chronic pancreatic insufficiency as reported in 50% of adults with IBD. Early detection of elevated pancreatic enzymes in IBD may help direct the management strategy, as treatment of the underlying inflammation in IBD may be the most important management for resolution of pancreatitis instead of cessation of therapy for fear of iatrogenic medication-induced pancreatitis.

In cystic fibrosis (CF), approximately 5-8% of the patients develop multilobular cirrhosis during the first decade of life. Annual screening (clinical examination, liver biochemistry, ultrasonography) is recommended in order to identify early signs of liver involvement, initiate ursodeoxycholic acid therapy and detect complications (portal hypertension and liver failure). Management should focus on nutrition and prevention of variceal bleeding. The gut may also be involved in children with CF. Gastroesophageal reflux is frequent, although often neglected and should be investigated by pH monitoring and impedancemetry, if available. Acute pancreatitis occurs in patients with persistent exocrine pancreatic activity. Intussusception, appendicular mucocele, distal intestinal occlusion syndrome, small bowel bacterial overgrowth and Clostridium difficile colitis should be considered in case of abdominal pain. Preventive nutritional support should be started as soon as possible after diagnosis of CF. Attainment of normal growth is one of the main goals and can be achieved with hypercaloric and salt supplemented food. Pancreatic enzyme replacement therapy should be started as soon as exocrine pancreatic insufficiency is confirmed and ingested immediately prior to meals with intake of fat-soluble vitamins. Curative nutritional interventions are more likely to be effective in the early stages of pulmonary disease. Feeding disorders, related to the physiopathology and the psychologic aspects of the disease are frequent. Repeated corporeal aggressions, associated with inappropriate medical and parental pressure, may increase the child's refusal of food. The multidisciplinary team should guide parents in order to avoid all intrusive feeding practices and promote pleasant mealtimes.

Chronic pancreatitis is a disease that leads to irreversible changes in the pancreatic morphology and function. The loss of function can lead to diabetes mellitus and exocrine pancreatic insufficiency. The inflammation and fibrosis can also lead to other complications including a chronic abdominal pain syndrome, metabolic bone disease, and pancretic cancer. This article reviews our current understanding of the mechanisms and management of these complications of chronic pancreatitis.

Chronic pancreatitis is a syndrome involving inflammation, fibrosis, and loss of acinar and islet cells which can manifest in unrelenting abdominal pain, malnutrition, and exocrine and endocrine insufficiency. The Toxic-Metabolic, Idiopathic, Genetic, Autoimmune, Recurrent and Severe Acute Pancreatitis, Obstructive (TIGAR-O) classification system categorizes known causes and factors that contribute to chronic pancreatitis. Although determining disease etiology provides a framework for focused and specific treatments, chronic pancreatitis remains a challenging condition to treat owing to the often refractory, centrally mediated pain and the lack of consensus regarding when endoscopic therapy and surgery are indicated. Further complications incurred include both exocrine and endocrine pancreatic insufficiency, pseudocyst formation, bile duct obstruction, and pancreatic cancer. Medical treatment of chronic pancreatitis involves controlling pain, addressing malnutrition via the treatment of vitamin and mineral deficiencies and recognizing the risk of osteoporosis, and administering appropriate pancreatic enzyme supplementation and diabetic agents. Cornerstones in treatment include the recognition of pancreatic exocrine insufficiency and administration of pancreatic enzyme replacement therapy, support to cease smoking and alcohol consumption, consultation with a dietitian, and a systematic follow-up to assure optimal treatment effect.

Cystic fibrosis (CF) is the most common genetic disorder that causes a significant damage in secretory epithelial cells due to the defective ion flux across the cystic fibrosis transmembrane conductance regulator (CFTR) Cl- channel. Pancreas is one of the organs most frequently damaged by the disease leading to pancreatic insufficiency, abdominal pain and an increased risk of acute pancreatitis in CF patients causing a significant decrease in the quality of life. CFTR plays a central role in the pancreatic ductal secretory functions by carrying Cl- and HCO3 - ions across the apical membrane. Therefore pathophysiological studies in CF mostly focused on the effects of impaired ion secretion by pancreatic ductal epithelial cells leading to exocrine pancreatic damage. However, several studies indicated that CFTR has a central role in the regulation of intracellular signaling processes and is now more widely considered as a signaling hub in epithelial cells. In contrast, elevated intracellular Ca2+ level was observed in the lack of functional CFTR in different cell types including airway epithelial cells. In addition, impaired CFTR expression has been correlated with damaged mitochondrial function in epithelial cells. These alterations of intracellular signaling in CF are not well characterized in the exocrine pancreas yet. Therefore in this review we would like to summarize the complex role of CFTR in the exocrine pancreas with a special focus on the intracellular signaling and mitochondrial function.

A 24-year-old black male presented with a 1-week obstructive jaundice and intermittent abdominal pain, with no significant weight loss and an unsuspicious abdominal exam. Blood chemistry showed a cholestatic pattern but a complete immunological and tumoral panel (anti-smooth muscle antibody, anti-mitochondrial antibody, anti-nuclear antibody, anti-neutrophil cytoplasmic antibody, anti-Smith, anti-double-stranded-DNA antibody (anti-dsDNA), complement C3/C4, carcinoembryonic antigen, CA 19-9 and IgG4) were all within normal limits. Abdominal ultrasound revealed dilatation of the intra and extra-hepatic bile ducts. CT scan showed an abnormal dilatation of the distal bile duct but no focal enlargement of the head of the pancreas. Endoscopic ultrasound suggested an inflammatory process but the magnetic resonance cholangio-pancreatography favored a neoplastic obstruction of the distal common bile duct. Fine-needle aspiration cytology was insufficient for definitive diagnosis and the patient underwent major surgery. Follow-up with mild exocrine pancreatic insufficiency treated with enzyme replacement.

Solid pseudopapillary neoplasms (SPN) of the pancreas are extremely rare epithelial tumors with low malignant potential. They account for only 1-2% of pancreatic lesions. These masses often go unnoticed and when they become symptomatic it is often due to mass effect on neighboring structures. We encountered an unusual presentation in a healthy 34-year-old female who was found to have elevated dehydroepiandrosterone (DHEA) and testosterone levels during the evaluation of irregular menses. Subsequent abdominal imaging revealed an enhancing 2.7 cm pancreatic tail mass that was concerning for a pancreatic neoplasm. The patient underwent endoscopic ultrasound which confirmed the presence of a hypoechoic, 2.3 x 1.7 cm mass in the pancreatic tail. An intact interface was seen between the mass and adjacent structures, suggesting the absence of local invasion. Fine needle biopsy was performed and cytology was consistent with SPN. The patient later underwent curative distal pancreatectomy, with subsequent normalization of her menses. SPN are generally inactive on laboratory screening modalities (i.e., AFP, CEA, CA 19-9, and CA 125) and our patient showed no evidence of pancreatic insufficiency, pancreatic parenchymal injury, abnormal liver function, or cholestasis. Similarly to our patient, most SPN are asymptomatic. One retrospective study (spanning 15 years) reported vague abdominal pain in ~70% of patients, on initial presentation. Symptoms of tumor mass effect were the second most common. To our knowledge, this is the first reported presentation of elevated DHEA and testosterone levels associated with a solid pseudopapillary tumor in the absence of an underlying adrenal lesion or dysfunction. Despite extensive workup, no alternate etiology or correlatable medical condition could be elucidated for our patient's hormonal dysregulation. We, therefore, recommend further review and investigation into this potential correlative relationship in an effort to guide the future diagnosis and management of this unusual neoplasm.
