Evaluation Of Intraoperative Touch Imprint Cytology Of Axillary Sentinel Lymph Node Accuracy In Comparison To The Permanent Histology Diagnosis. A prospective study Of 25 Invasive Breast Cancers.

Background: Intraoperative evaluation of axillary sentinel lymph node (SLN) in patients with breast carcinoma reduces the need of re-operations for axillary lymph node dissection. Various methods such as touch imprintcytology (TIC) and frozen section histology (FS) have been used to determine the SLN status intra-operatively. The sensitivity of intraoperative TIC examination on SLN is not consistent and varies in different studies.

Cardiac Involvement in Eosinophilic Granulomatosis with Polyangiitis (Churg-Strauss Disease): The role of cardiovascular magnetic resonance.

Eosinophilic granulomatosis with polyangiitis (EGPA), previously known as Churg-Strauss disease, is a rare vasculitis that affects small- to medium-sized vessels and has a propensity to involve the heart. Patients with cardiac involvement have a poor prognosis and usually require immunosuppressive treatment along with corticosteroids. Cardiovascular magnetic resonance (CMR) is a non-invasive diagnostic tool for detecting cardiac involvement and guiding the management plan.

Pulmonary Alveolar Microlithiasis: A Case Report.

Pulmonary alveolar microlithiasis (PAM) is a rare disease caused by a mutation in the SLC34A2 gene encoding the type IIb sodium phosphate cotransporter in alveolar type II cells. This results in the formation and accumulation of calcium phosphates crystals in the alveoli. Early in the disease, most patients are asymptomatic or might experience mild symptoms.

Pulmonary Hyalinising Granuloma: A report of two cases.

Pulmonary hyalinising granuloma (PHG) is a rare fibrosclerosing inflammatory lung condition of unknown aetiology. It is characterised by solitary or multiple pulmonary nodules that are usually found incidentally while imaging the chest for other reasons. We report two cases of histologically proven PHG diagnosed at the Royal Hospital, Muscat, Oman.

Nodular Pulmonary Amyloidosis Mimicking Metastatic Pulmonary Nodules: A case report and review of the literature.

Amyloidosis is a disorder characterised by the extracellular deposition of amyloid, a fibrillary protein, in various organs such as the lungs. Pulmonary nodular amyloidosis can mimic other lung conditions that present with pulmonary nodules, such as metastasis, sarcoidosis and hyalinising granuloma. We report a 60-year-old man who presented to the Royal Hospital, Muscat, Oman, in 2017 with a history of shortness of breath upon exertion, orthopnoea and bilateral lower limb swelling.

Repository of mutations from Oman: The entry point to a national mutation database.

The Sultanate of Oman is a rapidly developing Muslim country with well-organized government-funded health care services, and expanding medical genetic facilities. The preservation of tribal structures within the Omani population coupled with geographical isolation has produced unique patterns of rare mutations. In order to provide diagnosticians and researchers with access to an up-to-date resource that will assist them in their daily practice we collated and analyzed all of the Mendelian disease-associated mutations identified in the Omani population.

Gastrointestinal Basidiobolomycosis: First case report from Oman and literature review.

Gastrointestinal basidiobolomycosis (GIB) is a rare fungal infection with few reported cases worldwide. We report here the first case diagnosed in Oman in a previously healthy 5-year-old Omani female child who had been thought initially to have an abdominal malignancy. The case was referred to the Royal Hospital, Muscat, Oman, in July 2012.
