Computed Tomography and Magnetic Resonance Imaging for Congenital Hearing Loss: A Retrospective Study.

Objective: The aim of this study is to evaluate the relationship between the cochlear nerve and the anatomical structures of the cochlea and internal acoustic canal in patients with congenital hearing loss.

Materials And Methods: Temporal tomography and magnetic resonance images of 44 patients (88 ears) with non-syndromic congenital hearing loss were retrospectively analyzed between 2018 and 2021. Patients were divided into 2 groups according to cochlear nerve hypoplasia.

The usefulness of the Hounsfield unit and stone heterogeneity variation in predicting the shockwave lithotripsy outcome.

PURPOSE This study aimed to evaluate the use of stone density variation coefficient (SDVC) as an indicator of stone heterogeneity and previously reported parameters for predicting extracorporeal shock wave lithotripsy (ESWL) outcome in urinary calculi. Moreover, a new formula that could be used to predict ESWL success was suggested. METHODS A total of 850 patients, who underwent the first session of ESWL for urinary stones between 2015 and 2020, were examined, and 220 eligible patients were included in the study.

Frequency of typical and atypical computed tomography findings of COVID-19 and their effect on hospitalization.

Objective: This study aimed to determine the frequency of typical and atypical computed tomography (CT) findings of COVID-19 and their effect on hospitalization.

Methods: We retrospectively assessed 414 patients who were diagnosed with COVID-19 by real-time reverse transcription-polymerase chain reaction and who had lung involvement in their admission chest CT. We evaluated the frequency of typical and atypical chest CT findings and analyzed the relationship between typical and atypical findings of COVID-19 in patients treated in ambulatory versus inpatient settings.

Role of hepatosteatosis in the prognosis of COVID 19 disease.

Purpose: To measure the degree of fatty liver using non-contrast enhanced chest computed tomography (CT) and investigate its relationship with the severity and prognosis of coronavirus disease 2019 (COVID-19) in adult patients.

Methods: This retrospective study included consecutive patients who had been diagnosed with COVID-19 using real-time reverse-transcription polymerase chain reaction (RT-PCR) and subsequently underwent non-contrast enhanced chest CT between October 10 and December 10, 2020. Hepatic attenuation values were measured from Couinaud segments 2, 4, and 8 based on the CT images and the relationships between these values and the Pneumonia Severity Score (PSS), requirement of hospitalization, and the length of hospital and intensive care unit (ICU) stay were analyzed.

Merkel cell carcinoma of the gluteal region: A rare case report and literature review.

Merkel cell carcinoma (MCC) is a rare cutaneous neuroendocrine cancer that shows aggressive biological behaviour. Although it usually occurs on sun-exposed areas, it can sometimes be seen on non-sun-exposed sites. Here, we present the case of a 66-year-old woman with MCC arising from the right gluteal region that was treated with excision and adjuvant chemoradiotherapy.

Nutcracker syndrome complicating with renal abscess.

The nutcracker syndrome refers to compression of left renal vein between the superior mesenteric artery and aorta. Renal abscess consists of purulent and necrotic material localised to the renal parenchyma. These two entities are extremely rare and their coincidence has not previously been described in literature.
