Article Type: Image Article | First Published: October 31, 2018
The human nose is a complicated and smart part of the chemosensory system. Humans have multifaceted olfactory bulbs and orbitofrontal cortices, which provide them with more sensitive and dynamic abilities for the sense of smell, and as such humans could detect at least 1 trillion different smells. In the olfactory epithelium, odour molecules bind to olfactory receptors which are expressed in olfactory sensory neurons in the nose. Once an odorant binds to the receptor, the olfactory receptors tri...

Article Type: Image Article | First Published: October 04, 2018
An 81-years-old patient presented himself with dyspnea on exercise and dry cough, for 3 months. He was being treated to Waldenstrom's Macroglobulinemia in the prior 6 months and had non-requiring dialysis chronic renal failure as a consequence of the disease. High-resolution CT scan showed pulmonary micro-nodules with some predominance in the bronchial-vascular axis (Figure 1). Due to the findings in the CT scan and the high prevalence of the disease in Brazil, the patient was being treated empi...

Coronary-Bronchial Collaterals in Chronic Thromboembolic Pulmonary Hypertension
Caio Julio Cesar dos Santos Fernandes, Monique S Pessi, Ellen Pierre de Oliveira, Daniela Calderaro and Rogerio de Souza
Article Type: Image Article | First Published: October 03, 2018
Chronic thromboembolic pulmonary hypertension (CTEPH) is a form of hypertension pulmonary due to a mechanical obstruction of pulmonary arteries, which is caused by organized fibrotic thrombi. Consequences of pulmonary artery obstruction are an increase in pulmonary vascular resistance with pulmonary hypertension and heart failure. The main chest CT findings in CTEPH are the artery pulmonary enlargement and failure fill branches. Since there is a network of anastomotic channels linking the pulmon...

Giant Congenital Melanocytic Nevus: About a Case
Salma Salim, El Meknassi Ilham, Sqalli Asmae and Badredine Hassam
Article Type: Image Article | First Published: September 27, 2018
Giant congenital melanocytic nevi (GCMN) are a rare occurrence. They arise from mutations in either BRAF or NRAS genes. The major complications associated with GCMN are malignant melanoma and neurocutaneous melanosis. Management of GCMN is symptomatic. We present a rare case of a 20-year-old woman born with GCMN. Congenital melanocytic nevi (CMN) are large brown-to-black skin lesions caused due to genetic mutations which leads to abnormal proliferation of embryonic melanoblasts....

Olga Kedo, Karl Zilles, Nicola Palomero-Gallagher and Katrin Amunts
Article Type: Image Article | First Published: September 03, 2018
Subdivisions of the amygdala were identified in the color-coded receptor autoradiographs immediately adjacent to Nissl-stained sections in the right hemisphere at the level of the central nucleus. Color scales visualize the concentrations for each receptor (cholinergic muscarinic M2 or serotoninergic 5-HT1A receptors). After incubation of 20-μm thick coronal sections with the respective tritium-labelled ligand and exposition of the sections against the tritium-sensitive films, the films were de...
