Evaluation of the value of chest CT severity score in assessment of COVID-19 severity and short-term prognosis.

Background: Evaluations have shown that the severity of pulmonary involvement is very important in the mortality rate of patients with coronavirus disease 2019 (COVID-19). The purpose of this study was to evaluate the value of chest CT severity score in assessment of COVID-19 severity and short-term prognosis.

Materials And Methods: This study was a cross-sectional study with a sample size of 197 patients, including all patients admitted to Rasoul Akram Hospital, with positive polymerase chain reaction, to investigate the relationship between computed tomography (CT) severity score and mortality.

Predicting survival of Iranian COVID-19 patients infected by various variants including omicron from CT Scan images and clinical data using deep neural networks.

The rapid spread of the COVID-19 omicron variant virus has resulted in an overload of hospitals around the globe. As a result, many patients are deprived of hospital facilities, increasing mortality rates. Therefore, mortality rates can be reduced by efficiently assigning facilities to higher-risk patients.

The patients suspected of having other respiratory diseases including influenza, according to an infectious disease specialist, and those without chest CT scan were excluded.

The Valuable Role of Imaging Modalities in the Diagnosis of the Uncommon Presentations of COVID-19: An Educative Case Series.

The outbreak of coronavirus disease 2019 (COVID-19) in late 2019 rapidly turned into a global pandemic. Although the symptoms of COVID-19 are mainly respiratory ones, the infection is associated with a wide range of clinical signs and symptoms. The main imaging modality in COVID-19 is lung computed tomography (CT) scanning, but the diagnosis of the vast spectrum of complications needs the application of various imaging modalities.

Babu and Magon uterine closure technique during cesarean section: A randomized double-blind trial.

Aim: We compared the effectiveness of the Babu and Magon uterine closure technique and unlocked double-layer uterine closure on the integrity and thickness of the uterine scar.

Neurobrucellosis in a 9-year-old girl.

Brucellosis is a zoonotic multi-organ infectious disease most frequent in developing countries. Neurobrucellosis a quite rare but serious complication of brucellosis in the pediatric age group manifests with different neurological symptoms and signs. In the present case a 9-year-old girl was referred to our centre with a 9-months history of headache and back pain, facial nerve palsy and right upper limb weakness.

Epidemiologic and clinical findings of children with acquired immunodeficiency syndrome in four provinces of Iran.

Introduction: The human immunodeficiency virus (HIV) is still a remarkable challenge throughout the world, especially in developing countries. Despite the fact that HIV in children is becoming one of the most challenging diseases, it seems that pediatric AIDS in Iran is an unknown disease and there is a lack of studies about it. The aim of this study was to describe the characteristics of HIV-positive children who referred to the hospitals of Tehran, Kermanshah, Kurdistan, and Qom provinces of Iran.

Co-infection with bacterial and fungal endocarditis at scar tissue in an immunocompromised patient.

We present the case of a 65-year-old immunocompromised male with a history of kidney transplantation, diabetes, coronary artery bypass, and cardiac resynchronization therapy device implantation who was finally diagnosed with an unusual form of infective endocarditis due to co-infection of fungal and bacterial pathogens. He was afebrile at the time of admission and presented with decompensated heart failure and pneumonia. A spleen abscess was discovered incidentally and prompted us to search for a cardiac source of emboli.

Comparison of virtual bronchoscopy with fiberoptic bronchoscopy findings in patients exposed to sulfur mustard gas.

Background: Fiberoptic bronchoscopy (FB) is the best modality for evaluation of tracheobronchial endoluminal lesions. Virtual bronchoscopy (VB) with the aid of computed tomography (CT) makes it possible to reconstruct endoscopic-like visualization of major airways. Sulfur mustard (SM) used during the Iraq-Iran war affects respiratory tracts and can lead to tracheobronchial stenosis.

Histological evaluation of drill fragments obtained during osteoid osteoma radiofrequency ablation.

Objective: Osteoid osteoma (OO) is a benign bone tumor diagnosed mainly on the basis of the patient's history and radiological data. Histological evaluation may not be available before treatment. The aim of this study was to assess the diagnostic value of a histological evaluation of the bone fragments obtained during radiofrequency ablation (RFA).

Radiofrequency ablation of osteoid osteoma in atypical locations: a case series.

Background: Osteoid osteoma has a nidus surrounded by sclerotic bone with a size usually less than 20 mm. Its diagnosis is made on typical presentation of nocturnal pain and imaging findings. Excision of the niduses, which are often small and difficult to precisely identify, sometimes may result in resection of surrounding normal bone.
