Concurrent catatonia and COVID-19 infection in a demented patient: A case report.

Catatonia is a complex neuropsychiatric syndrome that comprises motor, behavioral and autonomic abnormalities. It occurs in the context of general medical, neurological, and psychiatric conditions. The study of catatonia in the elderly is particularly challenging due to the higher somatic and cognitive comorbidity, polymedication and the higher prevalence of delirium.

Large-vessel vasculitis induced by pegfilgrastim.

Granulocyte colony-stimulating factor (G-CSF) is increasingly being used to prevent febrile neutropenia associated with chemotherapy. Large-vessel vasculitis (LVV) has been recognized as a rare side effect of G-CSF treatment. We report a case of G-CSF associated LVV in a patient with breast cancer.

A Case of Brucellosis with Possible Ileal Involvement.

Introduction: Brucellosis is a zoonotic disease that can involve different organs and tissues. Fever, fatigue, lymphadenopathy, hepatosplenomegaly, cytopenia, and arthritis are the usual modes of presentation. Gastrointestinal manifestations of human brucellosis are common but documented ileal involvement is extremely rare.

Cystatin C: A Promising Marker of Renal Function in Patients with Systemic Lupus Erythematosus?

Purpose: Cystatin C has a higher correlation with glomerular filtration rate and a more significant clinical prognosis than creatinine. We sought to determine whether it is a marker of renal function different from creatinine (cystatin C potentially superior to creatinine), in patients with systemic lupus erythematosus.

Material And Methods: 37 patients with systemic lupus erythematosus were evaluated.

Acute kidney injury after major abdominal surgery: a retrospective cohort analysis.

Background. We analyzed the incidence, risk factors, and prognosis of acute kidney injury (AKI) in a cohort of patients undergoing major abdominal surgery. Methods.

Effect of fluoride gels supplemented with sodium trimetaphosphate in reducing demineralization.

Objectives: The objective of this study was to evaluate the in vitro effect of low-fluoride (F) gels supplemented with sodium trimetaphosphate (TMP) on enamel demineralization.

Materials And Methods: Bovine enamel blocks (n = 160) were selected based on surface hardness (SH) and divided into eight treatment groups (n = 20 per group): no F or TMP (placebo), 3 % TMP (3 %TMP), 5 % TMP (5 %TMP), 4,500 μg F/g (4,500), 4,500 μg F/g + 3 % TMP (4,500 3 %TMP), 4,500 μg F/g + 5 % TMP (4,500 5 %TMP), 9,000 μg F/g (9,000), and 12,300 μg F/g (acid gel). Blocks were subjected to demineralization/remineralization cycling for 5 days.

Hypocalcemic cardiomyopathy.

The association between hypocalcemia and heart failure is rare. There are few reported cases in the literature of this association, which is termed hypocalcemic cardiomyopathy. We report the case of a 61-year-old woman with no relevant medical history, admitted for progressively worsening exertional dyspnea, orthopnea and edema of the lower limbs for a previous month.
