Objective To describe two brothers with hypopituitarism who had been born by breech delivery and to discuss whether this condition corresponds to a familial form or to a pituitary stalk section as a result of the breech delivery. Methods We present the clinical, biochemical, and magnetic resonance imaging (MRI) characteristics of two Mexican brothers, 19 and 21 years old, with hypopituitarism and a history of breech delivery. Results Physical examination of both patients showed short stature with normal body proportions, an obviously younger appearance than that expected for their chronologic age, high-pitched voice, irregularly positioned teeth, no axillary or pubic hair, and prepubertal genitalia. Biochemical testing showed low thyroxine and free thyroxine values with inadequate or normal thy-rotropin, low basal testosterone, and mildly increased serum prolactin levels. Stimulation tests showed a normal and a delayed thyrotropin response to thyrotropin-releas-ing hormone, subnormal serum cortisol, considerably blunted growth hormone (GH) response to insulin-induced hypoglycemia, and absence of GH response to GH-releasing hormone in both cases. MRI showed an ectopic neuropituitary gland. In case 1, a caudal portion of a very thin pituitary stalk was observed, suggesting the preservation of a vascular component of the stalk. Because both parents of these brothers shared the major histocompatibility complex haplotype HLA-A*2301, B*3501, DRB1*0407, DQA1*03, DQB1*0201, consanguinity was suggested. Conclusion The phenotype of these patients differs from that described in families with POU1F1 (Pit-1) and PROP1 mutations. These cases are most likely related to an autosomal recessive gene mutation that warrants further research. To our knowledge, this is the first report of hypopituitarism in two brothers born by breech delivery. (Endocr Pract. 1999;5:143-147)

- Abstract
Granulomatosis with polyangiitis is a necrotising vasculitis with multisystem granulomatous inflammation which predominantly affects small blood vessels; it is associated with anti-neutrophil cytoplasmic antibodies (ANCAs). The purpose of this article is to describe the most common image findings in the areas of the head and the neck, in patients with granulomatosis with polyangiitis. To date no Mexican publications provide orientation on this point. The paranasal sinuses and the nasal septum are the best known areas, in head and neck, for this disease; however, disorders which may appear in eye sockets, ear, central nervous system, pituitary gland, and larynx, even without clinical manifestation at the time of image evaluation, should not be overlooked. It is important to opportunely report lesions due to granulomatosis with polyangiitis which suggest activity identified by imaging methods to the clinical physician and perform comparative studies to assess new lesions. In most cases active lesions identified by imaging are characterized by heightened signal intensity following administration of intravenous contrast medium, using T1 weighted sequences with fatty suppression. Image findings which suggest activity may be compared at different evolution times to determine possible remission or for histological confirmation. Long term, the presence of active lesions will help modify treatment, which may include starting corticoids or modifying or intensifying their use. [ABSTRACT FROM AUTHOR]

Introduction. Crohn's disease is a chronic inflammatory condition that may affect any segment of the digestive tract, from the mouth to the anus, and belongs to the group of inflammatory intestinal diseases (IID). Diagnosis is based on clinical, biochemical, endoscopic, radiological, and histopathological correlation. Magnetic resonance enterography is a non-invasive diagnostic method that does not use ionizing radiation and complements the diagnosis of Crohn's disease; it provides information on the extent, degree of inflammation, and possible complications. It plays an important role in classification and surgical planning. Objective. Describe findings by magnetic resonance enterography in Crohn's disease and conduct a review of the specialized literature. Material and methods. A cross-sectional, descriptive study was conducted. All patients with Crohn's disease who were admitted for consultation at the Salvador Zubiran National Institute of Medical Science and Nutrition Department of Gastroenterology Inflammatory Intestinal Disease Clinic, in the period October 2011 through April 2012 were included. All the patients underwent clinical evaluation, laboratory studies, and magnetic resonance enterography. Results. Magnetic resonance enterography found signs of active disease in 46.6% of the patients. The most common manifestations were wall thickening (80%), alteration of mucosal pattern (73%), and reinforcement of the wall (60%). The segment most commonly involved was the ileum (60%). Conclusions. Magnetic resonance may provide anatomic details, functional observations, and information in real time without the use of ionizing radiation in evaluation of Crohn's disease.

- Abstract
Because of the high frequency of late presentation of human immunodeficiency virus (HIV) disease in our population, we decided to explore the presence of myocarditis among people with HIV infection and advanced immunosuppression (less than 200 CD4
+ cells/μL) and to describe the inflammatory changes observed after combined antiretroviral therapy initiation in an observational, longitudinal, prospective cohort. We performed both cardiovascular magnetic resonance imaging and doppler transthoracic echocardiogram., (© The Author(s) 2020.

- Abstract
Background: Although return of function has been reported in patients undergoing proximal forearm transplantations (PFTs), reports of long-term function are limited. In this study, we evaluated the clinical progress and function 7 years postoperatively in a patient who underwent bilateral PFT., Case Presentation: A 58-year-old man underwent bilateral PFT in May 2012. Transplantation involved all of the flexor and extensor muscles of the forearm. Neurorrhaphies of the median, ulnar, and radial nerves were epineural and 7 cm proximal to the elbow. Immunosuppressive maintenance medications during the first 3 years postoperatively were tacrolimus, mycophenolate, and steroids, and later, tacrolimus, sirolimus, and steroids. Forearm function was evaluated annually using the Disabilities of the Arm, Shoulder, and Hand; Carroll; Hand Transplantation Score System; Short Form-36; and Kapandji scales. We also evaluated his grip and pinch force., Results: Postoperatively, the patient developed hypertriglyceridemia and systemic hypertension. He experienced 6 acute rejections, and none were resistant to steroids. Motor function findings in his right/left hand were: grip strength: 10/13 kg; key pinch: 3/3 kg; Kapandji score: 6/9 of 10; Carroll score: 66/80; Hand Transplantation Score System score: 90/94. His preoperative Disabilities of the Arm, Shoulder, and Hand score was 50 versus 18, postoperatively; his Short Form-36 score was 90. This function improved in relation with the function reported in the second year., Conclusions: Seven years following PFT, the patient gained limb strength with a functional elbow and wrist, although with diminished digital dexterity and sensation. Based on data presented by other programs and our own experience, PFT is indicated for select patients.

- Abstract
Background: Left atrial (LA) enlargement is a reliable predictor of adverse cardiovascular events, and reduced atrial function is an independent risk factor for mortality in patients with amyloidosis. The objective of this study was to characterize the LA function in Mexican patients with a confirmed diagnosis of hereditary transthyretin amyloidosis (amyloid transthyretin [ATTR])., Methods: All consecutive patients with diagnosis of hereditary ATTR who underwent a cardiac magnetic resonance study in the period from March 2016 to June 2017 were included in the study; the volumes and function of the left atrium were evaluated., Results: Patients were divided into two groups, one with and one without cardiac amyloidosis. Statistically significant differences were observed between both groups in terms of indexed maximal LA volume, 26 mL versus 35.9mL, p = 0.03; indexed minimal LA volume, 10.7 mL versus 13.6mL, p = 0.03; and indexed LA pre-contraction volume, 17 mL versus 22.4mL, p = 0.03. No statistically significant differences were observed between both groups when comparing neither different ejection volumes nor the different ejection fractions., Conclusions: Patients with hereditary ATTR with cardiac involvement have remodeling of the left atrium, with increased atrial volumes, without diminishing its function., (Copyright: © 2019 Permanyer.)

- Abstract
Objectives: To determine rates of incident erosive disease in early rheumatoid arthritis patients, to identify baseline predictors and to evaluate erosion's impact on patient-reported outcomes., Methods: 82 patients with ≤ 12 months of disease duration, ≥ 3 years of follow-up and conventional treatment were included. Consecutive evaluations assessed swollen and tender joint counts, treatment and comorbidity, acute reactant-phase determinations and patient-reported outcomes. Digitized radiographs of the hands and feet were obtained at baseline and yearly thereafter. RA was defined as erosive when at least one unequivocal cortical bone defect was detected. Descriptive statistics and Cox regression analysis were performed., Results: At baseline, 71 of the patients were ♀, population median (range) age was of 38.7 (16-78.2) years, 58 patients had antibodies and all the patients had active disease and substantial disability. Follow-up cohort was of 299.3 person-years. At last follow-up (49 ± 13.8 months), 28 patients developed erosions. Erosion's location was the feet, in 12 patients. Incident rates of erosive disease at one, two, three and four years were of 8.1, 12.8, 13.8 and 5.6 per 100 person-years, respectively. Higher C-reactive protein (HR: 1.20, 95%CI: 1.04-1.4, p=0.01) and positive antibodies (HR: 5.09, 95%CI: 1.08-23.86, p=0.04) were baseline predictors of incident erosive disease. Erosions had minor impact on patient-reported outcomes., Conclusion: Rheumatoid arthritis patients with antibodies and higher C reactive protein at baseline are at risk for incident erosions which appear most frequently at the feet. Up to 1/3 patients conventionally treated develop incident erosions, which minimally impact function., (Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
Uterine fibroids are a significant source of morbidity for women of reproductive age, and can result in substantial symptoms affecting their quality of life. Definitive treatment has traditionally been a myomectomy, but increasingly women are not prepared to undergo such an invasive procedure for a benign and usually self-limiting condition. Focused ultrasound ablation is one of the least invasive treatment options outside medical therapy and does not require an anesthetic.Magnetic resonance guided focused ultrasound (MRgFUS) ablation combines therapy delivered by an ultrasound transducer with imaging guidance for therapy and thermal feedback provided by magnetic resonance imaging. This paper provides an overview of the MRgFUS technique, including a brief description of the treatment system, guidelines for selection of patients and follow-up, and a comparison with other treatment techniques.

- Abstract
At the beginning of the evaluation of Coronary Artery Disease (CAD), Coronary Multidetector Computed Tomography (MDCT) was exclusively used to detect calcified plaques in coronary arteries through the Calcium Score, whose value by itself is limited. Nowadays, thanks to the technological advancements, potential clinical applications, with this method, include detection of coronary arterial stenosis, assessment of coronary bridges, and evaluation of anomalous coronaries. The intraluminal coronary stent evaluation is not possible yet, but this might become possible with the new-generation scanners. At the moment, the published results seem to be promising, nonetheless, the enthusiasm generated by this method should be accompanied by adequate training, as well as by its validation and certification.

- Abstract
It has been noted that "Good doctors use both individual clinical expertise and the best available external evidence, and neither alone is enough. " Evidence-based medicine (EBM) is defined as the process of systematically finding, critically appraising, and using contemporary research published in the medical literature as a basis to make decisions regarding individual patient care and health care policy. In radiology, including its diagnostic and interventional aspects, the principles and practice of EBM have not been thoroughly studied. In this brief review article, we describe key aspects of evidence-based radiology (EBR), concepts and steps followed in EBM and meta-analysis. The skills required to practice EBR are identified, and the roles of EBR in radiologic practice, education, and research are discussed. The application of EBM principles to diagnostic imaging facilitates the interpretation of imaging studies and produces a sound and comprehensive radiologic evaluation. This review could be useful for radiologists and clinicians at any stage of their training or career. It encourages the practice of EBM and EBR especially in developing countries.

- Abstract
The study of atherosclerotic disease in coronary arteries is fundamental since it is the first cause of death in the Western hemisphere. The gold standard for its diagnosis is invasive angiography, but it contributes to an increase in costs for this group of patients. Nowadays fourth generation computed tomography (CT) equipments can construct acquisition data of up to 256 images in only 400 milliseconds (ms), which is 900 to 1000 times faster than first generation apparatus. CT multidetector (CTMD) is the noninvasive choice diagnosis method for a vascular evaluation of the thorax. Its role in the study of the heart was limited, but today it is possible to obtain three-dimensional heart and whole body images in only seconds. CTMD is a fast, low-cost, noninvasive method that generates cardiac and extra cardiac images without adjacent structure interference. The higher temporal resolution due to an increase of the gantry's rotation and new reconstruction algorithms, as well as its higher spatial resolution and elevated time acquisition due to the presence of more detectors, have permitted CTMD to give significantly better and precise diagnosis of coronary arteries.

- Abstract
Objective: To describe two brothers with hypopituitarism who had been born by breech delivery and to discuss whether this condition corresponds to a familial form or to a pituitary stalk section as a result of the breech delivery., Methods: We present the clinical, biochemical, and magnetic resonance imaging (MRI) characteristics of two Mexican brothers, 19 and 21 years old, with hypopituitarism and a history of breech delivery., Results: Physical examination of both patients showed short stature with normal body proportions, an obviously younger appearance than that expected for their chronologic age, high-pitched voice, irregularly positioned teeth, no axillary or pubic hair, and prepubertal genitalia. Biochemical testing showed low thyroxine and free thyroxine values with inadequate or normal thyrotropin, low basal testosterone, and mildly increased serum prolactin levels. Stimulation tests showed a normal and a delayed thyrotropin response to thyrotropin-releasing hormone, subnormal serum cortisol, considerably blunted growth hormone (GH) response to insulin-induced hypoglycemia, and absence of GH response to GH-releasing hormone in both cases. MRI showed an ectopic neuropituitary gland. In case 1, a caudal portion of a very thin pituitary stalk was observed, suggesting the preservation of a vascular component of the stalk. Because both parents of these brothers shared the major histocompatibility complex haplotype HLA-A*2301, B*3501, DRB1*0407, DQA1*03, DQB1*0201, consanguinity was suggested., Conclusion: The phenotype of these patients differs from that described in families with POU1F1 (Pit-1) and PROP1 mutations. These cases are most likely related to an autosomal recessive gene mutation that warrants further research. To our knowledge, this is the first report of hypopituitarism in two brothers born by breech delivery.
