RESUMO
Background/Objective: A thrombosed internal carotid artery (ICA) aneurysm mimicking a pituitary adenoma can be catastrophic if unrecognized. We report a unique case of the rare presentation of ICA aneurysms masquerading as pituitary adenomas, which can preserve pituitary function when treated early. Case Report: A 54-year-old man with type 2 diabetes, aortic valve replacement, and stroke presented with sudden onset severe headache and left eye pain. Left third nerve palsy was noted. Laboratory studies showed low thyroid-stimulating hormone, follicle-stimulating hormone, luteinizing hormone, testosterone, and insulin-like growth factor 1 levels and baseline, post-30-minute, and post-60-minute cortisol levels of 16, 17, and 14 µg/dL, respectively, after adrenocorticotropic hormone stimulation. Magnetic resonance imaging of the pituitary revealed a heterogeneously enhancing 2.0 × 2.1 × 2.1-cm sellar/suprasellar mass with peripheral enhancement abutting the left cavernous sinus. Given the acute third nerve palsy without visual defects and magnetic resonance imaging findings, other sources of sellar occupying etiology were suspected. Therefore, carotid cerebral angiography was performed and revealed a mostly thrombosed left ICA aneurysm projected into the sellar/suprasellar region. The patient underwent successful endovascular treatment with a resolution of the cranial nerve palsy and hormonal abnormalities at 3-month follow-up. Discussion: Our case demonstrates the importance of swift recognition of ICA aneurysms masquerading as pituitary adenomas. Early recognition and treatment may lead to the complete resolution of presenting symptoms and hormonal deficiencies. Conclusion: Clinicians should have a high index of suspicion for ICA aneurysm in the differential diagnosis for a sellar mass. Careful evaluation is essential because misdiagnosis may lead to catastrophic consequences.
RESUMO
BACKGROUND & AIMS: Pharmacological management of obesity improves outcomes and decreases the risk of obesity-related complications. This American Gastroenterological Association guideline is intended to support practitioners in decisions about pharmacological interventions for overweight and obesity. METHODS: A multidisciplinary panel of content experts and guideline methodologists used the Grading of Recommendations Assessment, Development and Evaluation framework to prioritize clinical questions, identify patient-centered outcomes, and conduct an evidence synthesis of the following agents: semaglutide 2.4 mg, liraglutide 3.0 mg, phentermine-topiramate extended-release (ER), naltrexone-bupropion ER, orlistat, phentermine, diethylpropion, and Gelesis100 oral superabsorbent hydrogel. The guideline panel used the evidence-to-decision framework to develop recommendations for the pharmacological management of obesity and provided implementation considerations for clinical practice. RESULTS: The guideline panel made 9 recommendations. The panel strongly recommended the use of pharmacotherapy in addition to lifestyle intervention in adults with overweight and obesity (body mass index ≥30 kg/m2, or ≥27 kg/m2 with weight-related complications) who have an inadequate response to lifestyle interventions. The panel suggested the use of semaglutide 2.4 mg, liraglutide 3.0 mg, phentermine-topiramate ER, and naltrexone-bupropion ER (based on moderate certainty evidence), and phentermine and diethylpropion (based on low certainty evidence), for long-term management of overweight and obesity. The guideline panel suggested against the use of orlistat. The panel identified the use of Gelesis100 oral superabsorbent hydrogel as a knowledge gap. CONCLUSIONS: In adults with overweight and obesity who have an inadequate response to lifestyle interventions alone, long-term pharmacological therapy is recommended, with multiple effective and safe treatment options.

BACKGROUND/OBJECTIVES: The effect of total pancreatectomy with islet autotransplantation (TPIAT) on bone mineral density (BMD) in patients with CP is unknown. We aimed to assess bone health in patients with CP after TPIAT. METHODS: We measured BMD, BMD Z-score, and bone mineral content (BMC) for total body, lumbar spine, right and left hip in 78 patients before and after TPIAT using dual-energy X-ray absorptiometry (DXA, n = 78 pre-TPIAT, n = 65 paired pre- and 12 months post-TPIAT, n = 33 paired 12 and 18 months post-TPIAT), and tested for association with clinical history including age, smoking status, and medications using paired and two-sample t-tests, linear regression, and Fisher's exact test. Laboratory measures related to bone health were also assessed. RESULTS: In the patients with pre-TPIAT DXA, 12% had low BMD (Z-score ≤ -2). BMD, BMD Z-score, and BMC all decreased from pre-to 12 months post-TPIAT. BMD declined by 1.7%-4.1% with the greatest change at the hips. Adjusted for change in lean and fat body mass, DXA changes remained significant for total body and hip. Serum carboxy-terminal collagen crosslinks telopeptide and alkaline phosphatase increased at 12 months post-TPIAT, suggesting possible increased bone remodeling. BMD, BMD Z-score, and BMC did not change between 12 months and 18 months in any of the four regions (p > 0.6). CONCLUSIONS: TPIAT is associated with decreases in BMD in the body, lumbar, and hip regions of patients with CP in the first year after TPIAT but these appear to stabilize between 12 and 18 months after TPIAT.

CONTEXT: Body composition in total pancreatectomy with islet autotransplantation (TPIAT) has never been studied. OBJECTIVE: Determine whether presurgical body composition is associated with islet function and insulin sensitivity after TPIAT. METHODS: In 88 adults undergoing TPIAT (median age 41.0 years, IQR 32.8-48.0), beta-cell function and insulin sensitivity were assessed using mixed meal tolerance test and frequent sample intravenous glucose tolerance test before surgery and 12 and 18 months afterward. Body composition was measured by dual x-ray absorptiometry. Analyses used linear and logistic regression. RESULTS: Before surgery, 8 individuals (9.1%) were underweight, 40 (45.5%) normal weight, 20 (22.7%) overweight, and 20 (22.7%) obese. Overweight/obese patients had higher area under the curve C-peptide and lower insulin sensitivity index. Baseline body weight was positively associated with first-phase insulin secretion (AIRg) at 12 months (average 38.5 [SE 17.1] mU/L/min higher per extra kg; Pâ =â 0.03) and 18 months (38.3 [18.5]; Pâ =â 0.04), while baseline lean mass was inversely associated with AIRg at 12 months (-0.05 [0.02] per extra kg; Pâ =â 0.01) and 18 months (-0.05 [0.02]; Pâ =â 0.03). Percent gynoid fat was inversely associated with disposition index at 18 months (-206.0 [97.2] per extra percent; Pâ =â 0.04). Percent body fat and percent gynoid fat were associated with glucose effectiveness index at 18 months (1.9â ×â 10-3 [0.9â ×â 10-3] per extra percent; Pâ =â 0.04 and -1.96â ×â 10-3 [0.8â ×â 10-3]; Pâ =â 0.02, respectively). Insulin independence was not significantly associated with body weight or composition. CONCLUSIONS: Half of these chronic pancreatitis patients were overweight/obese; underweight was uncommon. Preoperative body weight and composition were associated with islet function but not insulin independence after TPIAT.

OBJECTIVE: Dystrophic scoliosis is a serious skeletal manifestation of neurofibromatosis 1 (NF1). The condition requires surgical intervention that is frequently associated with poor outcome due to the high rate of impaired bone healing, pseudoarthrosis, and loosening of the spinal instrumentation. New therapeutic approaches are needed to improve surgical outcomes. METHODS: Clinical, laboratory, and radiographic data are presented. RESULTS: A 54-year-old woman with severe NF1 related dystrophic scoliosis and 3 prior surgical interventions underwent revision of lumbar fusion with intraoperative recombinant human bone morphogenetic protein (rhBMP-2) for loosening and a fracture of the left vertical rod at the L4 pedicle screw connection. Two days after surgery, a computed tomography (CT) scan revealed a left posterior iliac periscrew fracture. Given a high risk of mechanical failure, zoledronic acid and asfotase alfa were also administered at 3 and 7 months after surgery. At 14 months after surgery, back pain improved, and a CT scan showed stable spinal fusion and a healed left posterior iliac screw fracture. CONCLUSION: Combination therapy including asfotase alfa with rhBMP-2 and bisphosphonate resulted in solid arthrodesis after spinal surgery in NF1-related dystrophic scoliosis.
RESUMO
BACKGROUND: The relation between malnutrition and pulmonary death in patients with cystic fibrosis (CF) has resulted in intensive nutritional intervention over the last few decades, leading to a significant decline in underweight and the emergence of overweight/obesity as a potential new problem. METHODS: We performed a cross-sectional database analysis of 484 adults with CF seen at the University of Minnesota CF Center between January 2015-January 2017, to determine the prevalence and pulmonary/cardiovascular risk factors associated with overweight and obesity in this population. RESULTS: Mean age was 35.2⯱â¯11.6 years. 5.2% were underweight (BMI<18.5â¯kg/m2), 62.6% normal weight (BMI ≥ 18.5-24.9â¯kg/m2), 25.6% overweight (BMI ≥ 25-29.9â¯kg/m2) and 6.6% obese (BMI ≥ 30â¯kg/m2). In the subgroup with severe genotypes, 25% had BMI ≥ 25â¯kg/m2. In the entire cohort, overweight/obese were likely to be older (ORâ¯=â¯1.04, p < 0.0001) and to have a mild CFTR genotype (ORâ¯=â¯3.33, pâ¯=â¯0.0003) and modestly elevated triglyceride levels (ORâ¯=â¯1.008, p < 0.0001). The prevalence of hypertension was higher in overweight (25%) and obese (31%) than normal (17%) or underweight (16%), pâ¯=â¯0.01. Total cholesterol levels were higher in overweight/obese versus normal/underweight (144-147â¯vs 123-131â¯mg/dL, pâ¯=â¯0.04) as were LDL levels (70-71â¯vs 53-60â¯mg/dL, pâ¯=â¯0.02), but all were within the normal range. Percent predicted FEV1 was higher in overweight/obese (78-81%) versus underweight (59%) and normal (70%), p < 0.0001, and overweight/obese experienced significantly fewer acute pulmonary exacerbations. CONCLUSIONS: Overweight/obesity is common in adults with CF including those with severe genotypes. Lung function is better in the overweight/obese and lipid levels are within the normal range, albeit higher than in normal/underweight.

CONTEXT: Pancreatic gastrointestinal stromal tumors (GIST) are rare mesenchymal tumor with only 6 cases reported to date. We report a case of pancreatic GIST presenting as hemorrhagic cyst. CASE REPORT: A 63-year-old female with past medical history of hypertension and pancreatic mass presented with fatigue. She was found to have anemia requiring blood transfusion. An abdominal CT scan revealed an 11x16 cm cystic mass at the pancreatic body that had increased in size compared with previous CT scan. Endoscopic ultrasound confirmed a large complex pancreatic mass and fine needle aspiration demonstrated gross bloody fluid. Cytology revealed a spindle cell lesion. Immunohistochemistry from cyst wall biopsy was strongly positive for CD34 and CD117 confirming the diagnosis of pancreatic GIST. CONCLUSION: We report a case of pancreatic GIST which presented as hemorrhagic cyst. Endoscopic ultrasound guided fine needle aspiration plays an important role in the diagnosis. Although it is an uncommon tumor, pancreatic GIST should be in differential diagnosis of hemorrhagic pancreatic cystic lesions as well as a rare cause of solid pancreatic lesions.
