RESUMO
We present the first documented case of successful treatment of orofacial granulomatosis by intralesional injections of a tumor necrosis factor α inhibitor to the lip. Our patient had rapid symptomatic improvement after 3 injections, and near resolution within 4 months of anti-tumor necrosis factor α therapy.

We report a case of autoimmune pancreatitis in a 9-year-old female who presented with persistent epigastric pain for 3 weeks. Magnetic resonance cholangiopancreatography (MRCP) showed both intrahepatic and extrahepatic biliary ductal dilatation. The common bile duct, along with the pancreatic duct, was noted to be dilated. Labs showed normal IgG and IgG4 levels and negative for autoimmune antibodies. Endoscopic ultrasound revealed the pancreatic head to be enlarged and surrounded by hypoechoic and lobulated lymph nodes. Biopsy of the pancreatic head showed chronic mildly active inflammation with fibrosis, acinar atrophy, and lymphocytic infiltrate. A diagnosis of autoimmune pancreatitis (AIP) was made, and she was treated with prednisone. The patient's symptoms improved quickly, and follow-up MRCP showed resolution of inflammatory changes and intrahepatic and pancreatic ductal dilatation.

OBJECTIVES: Infants with milk protein intolerance are usually switched to a casein hydrolysate or amino acid-based formula, which they continue to receive until 1 year of age, when they are rechallenged with a cow's-milk or soy protein formula. To investigate whether some of these infants actually become tolerant sooner, this study gathered preliminary data for establishing an empirical timetable for the resolution of milk protein intolerance. METHODS: This prospective, longitudinal cohort study enrolled infants <4 months of age receiving either breast milk or a cow's-milk or casein hydrolysate formula who presented to a pediatric subspecialty practice during an 18-month period and had a positive stool guaiac test. After having been successfully switched to a casein hydrolysate or amino acid formula, infants who had guaiac-negative stools for at least 2 consecutive months were rechallenged with the formula that had necessitated the most recent switch. RESULTS: Of the 25 patients enrolled in the study, 16 completed the food challenge and data collection protocol. Negative stool guaiac tests following rechallenge indicated resolution of milk protein intolerance by the time subjects reached an average age of 6.7â±â1.0 months (meanâ±âstandard deviation). By the age of 7 months, milk protein intolerance was resolved in 12 of the 16 infants, the remainder having resolved by 10 months. CONCLUSIONS: It may be reasonable to treat infants with milk protein intolerance for 2 to 3 months with a hypoallergenic formula, then rechallenge them at 6 months of age, usually without causing recurrence of the hematochezia. Rechallenging before 12 months old could result in cost savings to families and insurers.

The production of acid by the stomach is a tightly controlled physiological process that involves neural and hormonal mechanisms and the input of several epithelial cell types. The past several years have seen significant advances in our understanding of the molecular ontogenesis of the stomach and the factors controlling stomach innervation, as well as the differentiation of gastric epithelial cell lineages and their respective hormones/factors that influence acid production. The programmed development of each of these elements is exquisitely regulated and allows human neonates to produce gastric acid; it also helps us define expectations of acid production in preterm infants at all gestational ages.
