Fatal disseminated infection due to Sarocladium kiliense in a diabetic patient with COVID‐19

Sarocladium kiliense is a soil saprophytic mold with worldwide distribution, which can infect humans and other mammals, sporadically. The clinical manifestations include mycetoma, onychomycosis, keratomycosis, pneumonia, and arthritis. Here, we present a disseminated infection due to S. kiliense in a diabetic patient infected to coronavirus disease 2019 (COVID‐19) from Isfahan, Iran.     

Body mass index trajectories from childhood concerning emotional states in young adulthood: Tehran Lipid and Glucose Study

This study aimed to identify body mass index (BMI) trajectories from childhood and their relationships with depression, anxiety, and stress symptoms in young adulthood. A total of 687 children aged 4–18 years were recruited from the Tehran Lipid and Glucose Study. Throughout 18 years of follow-up, BMI was measured every 3 years for a maximum of 6 data points. Participants completed the depression, anxiety, and stress scale in their young adulthood (aged 22–36). The group-based trajectory modelling was applied to identify BMI patterns. The logistic regression model was used to assess the association between BMI trajectories and depression, anxiety, and stress symptoms in adulthood. Two BMI trajectories were identified from childhood to young adulthood: healthy weight (HW = 69.6%) and persistent increasing overweight/obesity (PIO = 30.4%). After adjusting for potential confounders, compared with the HW group, men in the PIO group were more likely to experience higher stress levels (OR: 1.62, 95% CI: 0.99–2.63; p = 0.05). No significant association was observed between the PIO trajectory and depression and anxiety among both sexes and stress symptoms in females. Our results highlight that developing overweight and obesity from childhood may be related to increased stress in males.     

Longitudinal stability of progression-related microglial activity during teriflunomide treatment in patients with multiple sclerosis

Background and purpose

The aim was to study brain innate immune cell activation in teriflunomide-treated patients with relapsing–remitting multiple sclerosis.

Methods

Imaging with 18-kDa translocator protein positron emission tomography (TSPO-PET) using the [¹¹C]PK11195 radioligand was employed to assess microglial activity in the white matter, thalamus and areas surrounding chronic white matter lesions in 12 patients with relapsing–remitting multiple sclerosis who had been treated with teriflunomide for at least 6 months before inclusion. Magnetic resonance imaging (MRI) was used to measure lesion load and brain volume, and quantitative susceptibility mapping (QSM) was used to detect iron rim lesions. These evaluations were repeated after 1 year of inclusion. Twelve age- and gender-matched healthy control subjects were imaged for comparison.

Results

Half of the patients had iron rim lesions. In TSPO-PET, the proportion of active voxels indicating innate immune cell activation was slightly greater amongst patients compared with healthy individuals (7.7% vs. 5.4%, p = 0.033). The mean distribution volume ratio of [¹¹C]PK11195 was not significantly different in the normal-appearing white matter or thalamus amongst patients versus controls. Amongst the treated patients, no significant alteration was observed in positron emission tomography distribution volume ratio, the proportion of active voxels, the number of iron-rim-positive lesions, lesion load or brain volume during follow-up.

Conclusions

Compared to controls, treated patients exhibited modest signs of diffuse innate immune cell activity, which was unaltered during follow-up. Lesion-associated smoldering inflammation was negligible at both timepoints. To our knowledge, this is the first study applying both TSPO-PET and QSM-MRI to longitudinally evaluate smoldering inflammation.     

Management of internal root resorption in the maxillary central incisor with fractured root using Biodentine

Biodentine is desirable to successfully manage internal root resorption, and the MTA apical plug backfilled with thermoplasticized gutta‐percha is suggested for the tooth with external apical root resorption.     

Occult breast cancer metastasis to the thyroid gland: Case report

Thyroid metastases of occult breast cancer are very rare. A 48‐year‐old female patient presented with chronic bone pain, bone, liver and thyroid nodules, and pleural effusion. Histopathological result of the thyroid showed poorly differentiated papillary thyroid carcinoma. However, clinical laboratory and immunohistochemistry studies showed breast origin of the thyroid lesion.
