Label-Free Quantitative Proteomics Analysis of Nasal Lavage Fluid in Chronic Rhinosinusitis with Nasal Polyposis.

(1) Background: Chronic rhinosinusitis (CRS) is a common chronic inflammation of the nasal mucosa and the paranasal sinuses. The pathogenesis of chronic rhinosinusitis (CRS) is multifactorial and, as of yet, not well understood. (2) Methods: Nasal lavage fluid samples were collected from patients diagnosed with chronic sinusitis with nasal polyposis (CRSwNP) (n = 10) and individuals without sinusitis (control group) (n = 10) who had no nasal complaints.

Nurses' attitudes towards patient safety and their relationship to adverse patient events in Oman.

Background: Adverse events (AEs) are major causes of mortality. Identification of nurses' attitudes towards patient safety and their impact on AEs is critical in enhancing safe practices.

Aim: To assess the relationship between attitudes towards patient safety and AEs as perceived by nurses working in Sultanate of Oman.

A biallelic variant of the RNA exosome gene, EXOSC4, associated with neurodevelopmental defects impairs RNA exosome function and translation.

The RNA exosome is an evolutionarily conserved complex required for both precise RNA processing and decay. Pathogenic variants in EXOSC genes, which encode structural subunits of this complex, are linked to several autosomal recessive disorders. Here, we describe a missense allele of the EXOSC4 gene that causes a collection of clinical features in two affected siblings.

The prevalence, epidemiological characteristics and mortality trends of inflammatory myopathies patients in Oman: the Prevision study.

Objectives: This research aims to investigate the prevalence, epidemiological characteristics, mortality rates, survival rates and the rate of malignancy in patients diagnosed with inflammatory myopathies (IIM) in Oman.

Methods: This is a longitudinal study, that covered a span of 16 years at eight rheumatology centres in Oman. The study included all adults and paediatric patients diagnosed with different types of idiopathic inflammatory myopathies (IIM) and who fulfil either the Bohan classification criteria or the 2017 EULAR/ACR classification criteria.

A Phosphaturic Mesenchymal Tumor Presenting as Reversible Metabolic Myopathy.

Tumor-induced osteomalacia (TIO) is a disorder in which the clinical signs and symptoms of osteomalacia and the biochemical abnormalities of hypophosphatemia, phosphaturia, and low serum levels of 1,25(OH)2 Vitamin D3 are secondary to a neoplasm. A 33-year-old woman presented with musculoskeletal pain and proximal myopathy with a duration of 2.5 years which was treated with Vitamin D supplements.

Indoxacarb poisoning presenting as methemoglobinemia: A case report.

A 34-year-old Sri Lankan man presented with multiple episodes of vomiting following accidental ingestion of 100 ml of indoxacarb (Avaunt). He had a significant saturation gap (discrepancy between oxygen saturation [98%] in blood gas analysis and saturation on pulse oximetry [70%] in finger pulse oximetry), the color of the blood was muddy brown, and the methemoglobin level (60%) was high in the blood gas analysis. A diagnosis of methemoglobinemia secondary to indoxacarb poisoning was made, and he was treated with methylene blue with a favorable outcome.

From Pseudotumor Cerebri to Neurobrucellosis: A Journey With Several Lessons.

We present a case admitted for evaluation of suspected idiopathic intracranial hypertension (IIH) with an unusual but important departure from the expected algorithm. A 31-year-old lady came with a two-week duration of a mild headache and one-week duration of double vision with no previously documented fever or any comorbidities. Clinically, she had papilledema and bilateral abducens palsy with no signs of meningeal irritation.

Del nido cardioplegia in adults: a retrospective observational study in comparison to modified St. Thomas cardioplegia in cardiac surgery.

Background: St. Thomas cardioplegia is commonly administered to adults, yet repeated dosing at brief intervals is required. Del Nido's cardioplegic solution provides a prolonged duration of safe myocardial arrest, yet it was primarily intended for pediatric cardiac surgery.

Short-term effects of antimicrobial stewardship programs on antibiotics usage, clinical outcomes, and multidrug resistant organisms in the post COVID-19 era.

Background: Antimicrobial resistance is associated with increasing mortality rates and the emergence of multidrug-resistant (MDR) organisms. There is scarcity of data on the short-term impact of Antimicrobial Stewardship Programs (ASP) on antibiotic usage, clinical outcome and MDR organisms' pattern following the COVID-19 pandemic. This study evaluated the short-term effects of ASP on antibiotic usage, clinical outcomes and MDR organisms' pattern in the post COVID-19 era.

Analysis of Blood Cultures from Major Burns Patients in a Tertiary Care Burn Unit in Oman.

Objectives: This study aimed to review the blood stream infections of major burn patients in a tertiary care burn unit to determine the most prevalent infecting organisms in order to have a better empirical therapy protocol.

Methods: This retrospective study analysed the blood stream infection of 155 major burn (>20% Total Body Surface Area [TBSA]) patients in Khoula Hospital, Muscat, Oman between January 2014 to December 2019.

Results: The median age was 33 years and 57.

Effectiveness of the Eutectic Mixture of Local Anaesthetics Cream in the Management of Arteriovenous Fistula Needle Insertion Pain in Patients Undergoing Haemodialysis.

This review aimed to assess the effectiveness of the eutectic mixture of local anaesthetics (EMLA) cream in the management of arteriovenous fistula (AVF) needle insertion pain in adult patients undergoing haemodialysis (HD) compared with other alternative interventions. The main search was conducted in November 2020 and updated in December 2021. In the search strategy, keywords and synonyms were used and multiple databases were searched with no date limitation to ensure a comprehensive search that would yield all studies relevant to the review and minimise location bias.

Posterior reversible encephalopathy syndrome secondary to malignancy-associated hypercalcemia: A case report.

Posterior reversible encephalopathy syndrome (PRES) is a reversible clinical syndrome usually characterized by a range of neurological manifestations and distinctive neuroimaging findings reflecting vasogenic edema. PRES has been described in the context of various clinical settings including: renal failure, blood pressure fluctuations, use of cytotoxic drugs, autoimmune disorders and eclampsia. Hypercalcemia is rarely associated with PRES.

Laparoscopic Management of Median Arcuate Ligament Syndrome: A Case Report.

Median arcuate ligament syndrome (MALS) is an uncommon disorder characterized by postprandial abdominal pain, vomiting, anorexia, and weight loss. The symptoms are due to the MAL compressing the celiac artery and irritating the celiac plexus/ganglion. We report the case of one patient who presented with chronic abdominal pain, bloating, vomiting, and weight loss.

Inactivation of DRG1, encoding a translation factor GTPase, causes a recessive neurodevelopmental disorder.

Purpose: Developmentally regulated Guanosine-5'-triphosphate-binding protein 1 (DRG1) is a highly conserved member of a class of GTPases implicated in translation. Although the expression of mammalian DRG1 is elevated in the central nervous system during development, and its function has been implicated in fundamental cellular processes, no pathogenic germline variants have yet been identified. Here, we characterize the clinical and biochemical consequences of DRG1 variants.

A Rare Differential Diagnosis of Air under the Diaphragm on Abdominal X-ray - Chilaiditi's Syndrome in a Child with Skin Wrinkle Syndrome.

Chilaiditi's syndrome is a rare disorder characterized by hepatodiaphragmatic interposition of the intestine. Only 30 cases of Chilaiditi's syndrome in children were reported in the literature and none in a child with skin wrinkle syndrome. Herein, we report a case of Chilaiditi's syndrome in a child with skin wrinkle syndrome.
