Late olfactory bulb involvement in COVID-19.

Transient or persistent hypo-anosmia is common in SARS‑CoV‑2 infection but olfactory pathway late-term morphometric changes are still under investigation. We evaluated late olfactory bulb (OB) imaging changes and their correlates with the olfactory function in otherwise neurologically asymptomatic COVID-19 patients. Eighty-three subjects (mean-age 43 ± 14 yr; 54 females; time-interval infection/MRI: 129±68 d) were affected by asymptomatic to mild COVID-19 in 2020 and 25 healthy controls (mean-age 40 ± 13 yr; 9 females) underwent 3T-MRI and olfactory function evaluation through anamnestic questionnaire and Sniffin' Sticks.

Network dysfunction of sadness facial expression processing and morphometry in euthymic bipolar disorder.

Facial emotion recognition (FER), including sadness, is altered in bipolar disorder (BD). However, the relationship between this impairment and the brain structure in BD is relatively unexplored. Furthermore, its association with clinical variables and with the subtypes of BD remains to be clarified.

Altered brain regional homogeneity is associated with depressive symptoms in COVID-19.

Background: COVID-19 is an infectious disease that has spread worldwide in 2020, causing a severe pandemic. In addition to respiratory symptoms, neuropsychiatric manifestations are commonly observed, including chronic fatigue, depression, and anxiety. The neural correlates of neuropsychiatric symptoms in COVID-19 are still largely unknown.

Epidemiologic, Imaging, and Clinical Issues in Bezold's Abscess: A Systematic Review.

Bezold's abscess is a deep neck abscess related to otomastoiditis. Due to the insidious clinical presentation, diagnosis can be extremely challenging, leading to delays in treatment and possible life-threatening complications. The literature currently provides a fragmented picture, presenting only single or small number of cases.

Bezold's abscess secondary to os tympanicum cholesteatoma in Goldenhar syndrome.

Objectives: The diagnosis of Bezold's abscess can be challenging especially when craniofacial malformations imply facial and cervical morphological asymmetries. In addition, craniofacial malformations might predispose to the occurrence and atypical diffusion pathways of suppurative processes originating from abnormally developed temporal bone structures.

Methods: A 30-year-old female presented with a left laterocervical swelling, worsening over time.

Gray matter volume covariance networks are associated with altered emotional processing in bipolar disorder: a source-based morphometry study.

Widespread regional gray matter volume (GMV) alterations have been reported in bipolar disorder (BD). Structural networks, which are thought to better reflect the complex multivariate organization of the brain, and their clinical and psychological function have not been investigated yet in BD. 24 patients with BD type-I (BD-I), and 30 with BD type-II (BD-II), and 45 controls underwent MRI scan.

Comparison of primary total hip replacements performed with a direct anterior approach versus the standard lateral approach: perioperative findings.

Background: Given the increasing demand for tissue-sparing surgery, the surgical approach is the subject of lively debate in total hip replacement. The aim of this paper is to compare the efficacy of the minimally invasive direct anterior approach and the standard lateral approach to total hip replacement surgery by observing intra- and perioperative outcomes.

Materials And Methods: The authors conducted a retrospective study on a group of 419 consecutive patients undergoing total hip replacement for coxarthrosis.
