Mycotic aortic aneurysm due to brucellosis

Brucellosis is a multisystem zoonotic disease. Mycotic aneurysm due to Brucella is rare and has no clear management approach. Here, we present two cases of mycotic aortic aneurysm due to Brucella. The first patient was treated with surgical resection of a symptomatic infrarenal abdominal aortic aneurysm combined with lifelong doxycycline and rifampicin. The second patient improved with conservative treatment including a 6-month course of antibiotics and regular clinical and radiologic monitoring. Through these cases, we hope to draw attention to this serious adverse effect of Brucella and the importance of management of its local arterial complications, especially in endemic areas

Recurrent syndrome of inappropriate antidiuretic hormone secretion due to tolterodine in an elderly male patient

Hyponatremia is defined as serum sodium of <135 mmol/L and equates with a low serum osmolality once translocational hyponatremia and pseudohyponatremia are ruled out. True hyponatremia develops when normal urine-diluting mechanisms are disturbed. In elderly patients, this complication is not uncommon, especially in nursing homes and assisted living facilities. Medications are often the most common cause of hyponatremia in these patients. Herewith, we reported a 65-year-old Saudi male, a known case of benign prostatic hypertrophy and hypertension, who developed recurrent hyponatremia secondary to tolterodine. To our knowledge, this is the fifth case reported in literature of such association

Evaluation of Smart Chromatic Technology for a Single-Shade Dental Polymer Resin: An In Vitro Study

The aim of the study was to assess the color matching ability and color stability of a single-shade resin-based composite (Omnichroma—OM) in comparison to a conventional dental composite. One hundred and sixty lower molar acrylic teeth in four different shades (B1, B2, A3, and C3) were prepared with class I cavities. Eighty teeth were divided into two groups based on the two resin composite materials (OM and Filtek Z-350 (FT)) for cavity restoration. Three groups were included in the color matching assessment, namely Gp 1-FT, Gp 2-OM-light cured (C), and Gp 3-OM-uncured (UC) groups. The color assessment was performed prior to cavity restoration and after cavity filling and before and after light curing to detect color matching. The 80 remaining teeth were restored with OM (n = 40) and FT (n = 40); half (n = 40) were submerged in coffee and the other half (n = 40) were submerged in cola for 2 weeks. The color stability was assessed by calculating material color (spectrophotometry) changes (∆E) before and after staining in immersion medium. The means and standard deviations of the ∆E values relating to color matching and color stability (stain resistance) among the study groups were analyzed using ANOVA and Tukey’s post hoc test. FT showed significantly better color matching (lower ΔE) in comparison to OM-UC specimens for shades B1, B2, and A3 (p &lt; 0.01). Regarding the color stability in cola, the FT samples showed significantly lower ΔE values (indicating better color stability) compared to OM samples for all four shades (p &lt; 0.01). The ΔE values of OM and FT samples in coffee were comparable (p &gt; 0.01), showing comparable color stability. The color matching ability of the single-shade resin composite (OM) was influenced by the tooth color. The conventional resin composite showed better color matching than the single-shade composite (OM). The color stability of the single-shade resin composite (OM) was dependent on the staining medium. The OM composite showed more compromised color stability than the conventional resin composite in cola and comparable color stability to conventional resin composite in coffee

Sarcoidosis with multiple organ involvement associated with necrotizing crescentic glomerulonephritis

We report a case of a young Saudi male who presented with generalized body weakness and easy fatigability associated with fever, night sweating, loss of weight and appetite, and renal impairment. He was diagnosed as a case of sarcoidosis, and renal biopsy report was consistent with necrotizing crescentic glomerulonephritis (GN). Immunosuppressive medication was started to help halting the progression to renal failure and stabilize renal function. To the best of our knowledge, the association between sarcoidosis and crescentic GN has been reported in only few cases in literature
