A Biochemical Analysis beyond the Muscle Contraction and its Relation with Isaac Syndrome
Valdemir Aquino de Freitas Neto
Article Type: Review Article | First Published: December 31, 2020
Isaac Syndrome is an autoimmune disease related to the involuntary contraction of skeletal muscles. The author, thus, is going to connect it with the process of muscle contraction through a biochemical study, analysing the pathway from a nervous impulse to the open of voltage-gated Potassium channels and the releasing of Ca2+ on myofibrils. This paper intends to introduce this rare disease and to induce further researches in order to find a cure. The muscle contraction process starts on the Na+/...

A Novel Case of Maffucci Syndrome and a Likely High-Grade Lymphoma
Fleming S, Player P, Ladani S, Miall F, Goldney J and Levy MJ
Article Type: Case Report | First Published: November 16, 2020
A 54-year-old male with a history of Maffucci syndrome and Marginal Zone Lymphoma, presented with a 4-week history of headache, right-sidedptosis and diplopia. Whole-body imaging revealed a mass in the pituitary fossa that was likely lymphomatous. Despite diagnostic uncertainty, the mass was treated as transformation of Marginal Zone Lymphoma to a high-grade lymphoma. This report analyses how and why the multi-disciplinary team treated the patient without a biopsy. The case highlights a possible...

Distal Arthrogryposis Type Six and Systemic Lupus Erythematosus, in a Girl: First Pediatric Case
Houda Nassih, R El Qadiry, A Bourrahouat, and I Ait Sab
Article Type: Case Report | First Published: November 12, 2020
Arthrogryposis type six is one of the distal arthrogryposes. It associates arthrogryposis of the hands and sensorineural deafness. Male-to-male transmission was observed. No gene has been identified to date. We report a unique case of a girl presenting with congenital arthrogryposis-like hand anomaly, sensorineural deafness, and acute onset of systemic lupus erythematosus (SLE). Arthrogryposis-like hand and deafness syndrome or distal arthrogryposis type 6 (DA6) is characterized by an arthrogryp...

A Rare Case of an Ascending Aorta and Aortic Arch Aneurysm with an Aberrant Right Common Carotid Artery and a Proximal Descending Aortic Ectasia
Mikhail M Olalo, MD and Syril Bren P Guillermo, MD, FPCP, FPCC
Article Type: Case Report | First Published: November 12, 2020
Ascending aortic aneurysms are asymptomatic and are usually discovered as an incidental finding on chest imaging. However, larger aneurysms can present with symptoms resulting from compression of surrounding structures including the trachea, bronchi, and the esophagus which can result in hoarseness, cough chest pain or back pain. The presence of an aortic arch anomaly, specifically an aberrant right common carotid artery, in a background of an aortic arch aneurysm is extremely rare with a worldw...

Carotid Paragangliomas Related to Form Involving Multiple Systems (Syndromes and Diseases): A Systematic Literature Review
Francisco S Lozano-Sánchez MD, PhD, Angel Muñoz MD, PhD, José A de las Heras MD, PhD, Rogelio González-Sarmiento, MD, PhD and M Begoña García-Cenador MD, PhD
Article Type: Review Article | First Published: November 12, 2020
Carotid paragangliomas are infrequent tumours, generally single, non-functional and benign. Nevertheless, the biology of these tumours occasionally means they are bilateral, multicentric, functional and malignant. Such infrequency and the different ways they manifest themselves pose a diagnostic/ therapeutic challenge that is reflected in the final outcomes. According to the Shamblin classification, 75% of carotid paragangliomas are either Type I (tumour smaller than 4 cm, weakly attached to the...

Case Report: Tolosa-Hunt Syndrome Associated with a Chest Mass in a Pediatric Patient
William Im, Marla Sacks, Laura Goodman and Andrei Radulescu
Article Type: Case Report | First Published: October 02, 2020
Tolosa-Hunt Syndrome is a rare disease with an incidence rate of about one in one million per year worldwide. It is caused by granulomatous, nonspecific inflammation of the cavernous sinus, which results in severe headaches, eye pain, and ophthalmoplegia. This is the case of a previously healthy 10-year-old male with a family history significant for Non-Hodgkin’s Lymphoma and Squamous cell carcinoma who presented to the Emergency Department (ED) with an intense recurring headache and ophthalmo...

Article Type: Case Report | First Published: October 02, 2020
Fibrous dysplasia is an uncommon, bone development abnormality characterized by the replacement of normal cancellous bone by fibrous tissue and immature woven bone. Classified according to the number of affected bones, fibrous dysplasia can affect any bones of the skeletal system, with long bones the most commonly documented site of involvement. Typically, diagnosis is based on clinical, radiological and histological findings. However, due to its broad clinical spectrum, it remains a therapeutic...

The mortality rate of Hemophagocytic Syndrome (HPS) is 26.5%-74.8%. Malignant neoplasms, hyperferritinemia, thrombocytopenia, older age, hypertriglyceridemia, and prolonged prothrombin are considered to be adverse prognostic factors. This study describes the underlying features of patients survivors and non-survivors with HPS from one hospital between 2005-2019. This is a retrospective study. We included patient with HPS diagnosis based on the HLH-2004 criteria, or who presented hemophagocytic c...
