Solitary vertebral metastasis of unknown primary renal cell carcinoma treated with surgical resection plus tyrosine kinase inhibitor: A case report.

Introduction: Although 25-30 % of renal cell carcinomas (RCC) might be diagnosed in metastatic stage, occurrence of metastatic renal cell carcinoma (mRCC) as a cancer of unknown primary site (CUP-mRCC) is extremely rare.

Glycemic Characteristics and Clinical Outcomes in Patients with COVID-19 Admitted to Referral Shahid Sayad Shirazi Hospital in Gorgan, North of Iran.

Background: Diabetes mellitus (DM) is one of the most common chronic diseases, the main manifestation of which is hyperglycemia, and is accompanied by many complications. Since the outbreak of the coronavirus disease 2019 (COVID-19) pandemic, several studies have reported the occurrence of various complications associated with different degrees of hyperglycemia in COVID-19 patients. The aim of the present study was to investigate the glycemic characteristics and clinical outcomes in patients with COVID-19.

Hemoptysis as a rare manifestation of missed blunt thoracic aorta injury, a case report.

Introduction And Importance: Blunt thoracic aorta injury is one of the most fatal injuries in multiple trauma patients and most of these injuries lead to death at the scene. Some patients remain undiagnosed because of the lack of specific symptoms for these injuries. Hemoptysis as a presentation of a neglected blunt aortic trauma is a very rare condition.

Migration of nephrostomy tube into right atrium during percutaneous nephrolithotomy: A case report.

Introduction And Importance: Percutaneous nephrolithotomy (PCNL) is one of the most commonly performed surgeries in urology. Due to blind nature of the procedure unexpected events are inevitable. Misplacement of percutaneous nephrostomy (PCN) during PCNL into the venous system is one of the rarest complications causing great stress to both physician and the patient.

Axillary artery aneurysm in a construction worker, presentation of a rare case.

Introduction And Importance: Axillary artery aneurysm is a rare anomaly in the vascular system of the upper extremity. Most of these aneurysms are false aneurysms and secondary to trauma. They can cause compressive symptoms as well as thromboembolic events leading to limb loss or even rupture as a life-threatening complication.

Cushing's syndrome as a paraneoplastic feature of renal cell carcinoma: A case report.

Cushing's syndrome has been believed to be a paraneoplastic syndrome of renal cell carcinomas. However, there appears to be a dearth of compelling evidence to substantiate this notion. The only eligible documentation of Cushing's syndrome due to ectopic adrenocorticotropic hormone secretion by renal cancer in English literature dates back to 1988, and it pertains to a deceased patient discovered during an autopsy.

Idiopathic true aneurysm of the proximal radial artery with the appearance of an enlarging mass: A case report.

Introduction And Importance: Aneurysm of the radial artery is one of the rare cases in the field of vascular surgery, and its diagnosis and management is one of the challenges in this era. Without proper diagnosis and treatment, it may affect the patient's lifestyle and reduce the quality of life because of pain and limitation in activity. Importantly, it may cause limb or life threatening complications including arterial thromboembolism and aneurysm rupture.

A Review of Hyperglycemia in COVID-19.

Diabetes mellitus (DM) is one of the most common chronic metabolic disorders worldwide, which increases the risk of common and opportunistic infections. Following the coronavirus disease 2019 (COVID-19) pandemic, a higher incidence rate, more severe forms of the disease, and exacerbation of hyperglycemia and its complications have been observed in patients with DM. Moreover, stress-induced hyperglycemia has been observed in many hospitalized nondiabetic patients after contracting COVID-19.

Does celecoxib with sodium valproate have an augmentation effect on acute mania in bipolar disorder? A double-blind controlled clinical trial in Iran.

Inflammatory processes in the brain play a role in acute mania etiopathogenesis. There is little evidence indicating the efficacy of celecoxib adjuvant therapy in treatmenting of manic episodes of bipolar disorder. Therefore, this clinical trial aimed to assess the celecoxib effect on treating acute mania.

Relationship of serum estradiol and progesterone with symptoms and sex difference in schizophrenia: A cross-sectional study in Iran.

Background: Schizophrenia is a devastating disease characterized by frequent relapses, cognitive decline, and emotional and functional disability, with unknown causes. The phenomenology and clinical course of schizophrenic disorders are different between the two genders, which is thought to be related mainly to the effects of steroid sex hormones on the nervous system. Regarding inconsistencies in the studies, we aimed to compare the levels of estradiol and progesterone between schizophrenia patients and healthy individuals.

Incarceration of small bowel following percutaneous nephrostomy tube insertion.

Percutaneous nephrostomy has become a well-established technique for providing permanent or temporary drainage of an obstructed urinary system for decades. Although it is generally considered a safe intervention, some complications might be life threatening. Here we present a case of bilateral nephrostomy insertion due to T-cell lymphoma, that presented with signs of bowel obstruction 3 weeks after intervention.

Evaluation of Specific Antibody Responses in Patients with Selective IgA Deficiency and Ataxia Telangiectasia.

Background: Specific Antibody Deficiency (SAD) is a primary immunodeficiency disease (PID) characterized by the occurrence of recurrent infections and inadequate antibody response to polysaccharide new antigens.

Objective: This study aims to determine the titer of specific antibodies against unconjugated 23-valent pneumococcal polysaccharide vaccine (PPSV-23), the presence of SAD, and its association with clinical and laboratory findings in Ataxia-telangiectasia (A-T) and selective immunoglobulin A deficiency (SIgAD) patients.

Methods: 32 A-T patients and 43 SIgAD patients were included in this cross-sectional study.

Potentilla reptans L. postconditioning protects reperfusion injury via the RISK/SAFE pathways in an isolated rat heart.

Background: Our previous study indicated that Potentilla reptans root has a preconditioning effect by its antioxidant and anti-apoptotic effects in an isolated rat heart ischemia/reperfusion (IR) model. In the present study, we investigated the post-conditioning cardio-protective effects of Potentilla reptans and its active substances.

Methods: The ethyl acetate fraction of P.

Lymphocytes subsets in correlation with clinical profile in CVID patients without monogenic defects.

Common variable immunodeficiency (CVID) patients experience clinical manifestations rather than recurrent respiratory infections including autoimmunity, enteropathy, and lymphoproliferation. We evaluated the correlation of lymphocyte subpopulations with such manifestations. Twenty-six genetically unsolved CVID patients were subdivided into four phenotypes: infection only (IO), autoimmunity (AI), chronic enteropathy (CE), and lymphoproliferative disorders (LP) and examined for lymphocyte subsets by flow cytometry and TCD4 proliferation by Carboxyfluorescein succinimidyl ester (CFSE) test.

Totally implanted chemotherapy port catheters: literature review and report of four cases.

Totally implantable catheters tend to be the most popular choice because once installed they allow permanent access to a deep vein, which is gained by puncturing the port rather than a vein. In this article, we explain four cases of chemotherapy port complications: superior vena cava (SVC) syndrome in a metastatic colorectal cancer patient who presented with bilateral mastitis, snare technique for removal of migrated catheter line, carotid artery placement of a port in a 5-year-old child that was referred to our hospital from a pediatric center and adhesive port tip in the heart that finally we left the port . In SVC syndrome, treatment should be guided by the severity of symptoms, etiology of the obstruction, prognosis of the patient and treatment goals.

The fatty acid-binding protein (FABP) decreases the clinical signs and modulates immune responses in a mouse model of experimental autoimmune encephalomyelitis (EAE).

Background: An increasing body of studies has shown that Fasciola hepatica can affect immune responses. This study explored whether the fatty acid-binding protein (FABP) of F. hepatica can modulate the immune system in a mouse model of experimental autoimmune encephalomyelitis (EAE).
