Left atrial and ventricular deformation: alterations and predictive value of echocardiography parameters in end-stage renal disease patients after kidney transplantation.

Aims: End-stage renal disease (ESRD) patients are prone to alterations in cardiac haemodynamics specifically on the left ventricle (LV) and left atrial (LA) functions usually due to factors like uraemia, fluid overload, and inflammation. While studies on LV function in ESRD exist, research on LA function is limited. Successful kidney transplant (KTx) is believed to reverse pathological cardiac remodelling, and monitoring changes in cardiac strain before and after transplantation may guide pre- and post-transplant care.

Opium use and gastrointestinal cancers: a systematic review and meta-analysis study.

Aim: The current systematic review and meta-analysis aimed to assess the association between Gastrointestinal (GI) cancers and opium use.

Background: GI malignancies are a global public health issue and are associated with many risk factors including genetic and lifestyle factors.

Methods: PubMed, Web of Science, Embase and Scopus and the Google Scholar search engine in addition to Persian databases including Magiran and SID were searched using relevant keywords.

Empty sella in somatotropic pituitary adenomas; a series of 23 cases.

Purpose: We aimed to investigate empty sella syndrome in somatotrophic pituitary adenoma for possible etiology, complications, and treatment options.

Method: Among over 2,000 skull base masses that have been managed in our center since 2013, we searched for growth hormone-producing adenomas. Clinical, surgical, and imaging data were retrospectively collected from hospital records to check for sella that lacked pituitary tissue on routine imaging.

A rare case of aneurysmal bone cyst of the anterior clinoid process in an 18-year-old female mimicking optic neuritis.

Background: Aneurysmal bone cyst (ABC) is an uncommon, benign, vascular multicystic bony lesion that most frequently develops in the first two decades of life. The metaphysis of long bones, pelvic, and vertebral column are the most common locations. The precise underlying pathophysiology of ABCs formation remains unclear; however, it is believed that reactive processes subsequent to trauma or vascular disturbance may play an important role.

A case report of clubbing as the initial sign of systemic sclerosis sine scleroderma: A rare possible presentation.

Key Clinical Message: Even in the absence of characteristic cutaneous symptoms of scleroderma, systemic sclerosis should be considered in the differential diagnosis of patients initially diagnosed with idiopathic interstitial lung disease.

Abstract: Systemic sclerosis (SSc) is an idiopathic connective tissue disorder characterized by multisystem involvement. Although skin thickening is a hallmark manifestation of SSc, a subset known as systemic sclerosis sine scleroderma (ssSSc) presents with internal organ involvement and positive serologic markers in the absence of significant cutaneous manifestations.

Waldenström's macroglobulinemia with necrotic extremities: A case with challenging diagnosis.

Key Clinical Message: Waldenström's macroglobulinemia may begin with constitutional symptoms that are common in primary care settings and it is crucial for physicians to be aware of the potential complications of hyperviscosity syndrome and to employ the appropriate diagnostic methods in order to achieve better outcomes.

Abstract: Waldenström's macroglobulinemia (WM) refers to a type of lymphoplasmacytic lymphoma distinguished by the hyperproliferation of plasma cells, lymphocytes, and plasmacytoid lymphocytes. The disease is primarily diagnosed by increased monoclonal immunoglobulin M (IgM) levels and lymphoplasmacytic cell infiltration into the bone marrow.

Heparin induced thrombocytopenia in pregnancy: A therapeutic challenge case report and literature review.

The anticoagulants of choice for the prevention and treatment of venous thromboembolic disease during pregnancy are unfractionated heparin and low-molecular-weight heparin. Heparin-induced thrombocytopenia (HIT) is introduced as a rare but critical side effect of heparin products raising the thromboembolic event paradoxically. Here, we present a case of HIT in pregnancy with challenging management due to coincidence of lupus anticoagulant (LA) and limited anticoagulant options in the pharmaceutical market of our country of residence.

Paraneoplastic acute eosinophilic pneumonia due to carotid angiosarcoma: A rare case.

Key Clinical Message: This case report emphasizes that we should analyze a patient's signs and symptoms as a whole rather than relying exclusively on a common pattern to diagnose the condition and indicates that thorough histological investigation and sample collection are needed to accurately diagnose this malignancy.

Abstract: Angiosarcoma is a rare, fatal, and poorly understood malignant tumor of vascular endothelial cells which is a challenging disease to diagnose in the clinical settings and requires early diagnosis to achieve a favorable prognosis. Paraneoplastic syndromes associated with angiosarcoma can include hypercoagulability, thrombocytopenia, anemia, fever, weight loss, and night sweats.

Endoscopic versus Microsurgical Resection of Third Ventricle Colloid Cysts: A Single-Center Case Series of 140 Consecutive Patients.

Background: Both endoscopic and microsurgery transcortical resection methods are used for colloid cysts of the third ventricle but they have not been compared regarding benefits and pitfalls.

Methods: Data of patients who underwent surgical resection of third ventricle colloid cyst via either endoscopic or microsurgery approach by a single surgeon from 2005 to 2020 were retrospectively collected. After administration of criteria, 140 records were retrieved (60 patients through endoscopic resection and 80 patients by a transcranial microsurgery approach).
