A Rare Case of Dual Metachronous Primary Malignancies, Chronic Myeloid Leukemia, and Tongue Carcinoma in a Patient With Long-Standing Systemic Lupus Erythematosus: A Case Report and Review of Literature.

Patients with long-standing autoimmune diseases like systemic lupus erythematosus (SLE) are at a higher risk of developing hematological malignancies. However, chronic myeloid leukemia (CML) has rarely been reported in patients with SLE. Advancements in medical diagnostics and treatment have led to the life expectancy of SLE and CML patients moving closer to that of the general population, and it is not uncommon to encounter more than one malignancy in a cancer survivor.

Disseminated Basidiobolomycosis Caused by Basidiobolus omanensis in a Child with Acute Lymphoblastic Leukemia (ALL). Case Report and Literature Review.

Basidiobolomycosis is an uncommon fungal infection caused by the genus Basidiobolus. In immunocompetent children, it usually causes cutaneous infection and rarely affects the gastrointestinal tract, and it is extremely rare for the disease to spread. The present study reports the first case of disseminated basidiobolomycosis caused by Basidiobolus omanensis in a child with acute lymphoblastic leukemia who died as a result of uncontrolled infection and multi-organ failure despite surgical and antifungal therapy with L-AMB and voriconazole.

First Dark Matter Search Results from the LUX-ZEPLIN (LZ) Experiment.

The LUX-ZEPLIN experiment is a dark matter detector centered on a dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility in Lead, South Dakota, USA. This Letter reports results from LUX-ZEPLIN's first search for weakly interacting massive particles (WIMPs) with an exposure of 60 live days using a fiducial mass of 5.5 t.

Mothers' Intention to Vaccinate Their Children Aged 5-11 Against COVID-19: A Cross-sectional Survey.

Objectives: COVID-19 vaccines lower the risk of infection hospitalization, and death. Despite the safety and effectiveness of COVID-19 vaccines, some caregivers are hesitant to vaccinate their children against COVID-19. In this study, we explored the factors that influence Omani mothers' intentions to vaccinate their 511 year-old children.

Mathematical analysis of a COVID-19 model with different types of quarantine and isolation.

A COVID-19 deterministic compartmental mathematical model with different types of quarantine and isolation is proposed to investigate their role in the disease transmission dynamics. The quarantine compartment is subdivided into short and long quarantine classes, and the isolation compartment is subdivided into tested and non-tested home-isolated individuals and institutionally isolated individuals. The proposed model has been fully analyzed.

Features and diagnostic accuracy of fine needle aspiration cytology of thyroid nodules: retrospective study from Oman.

Background: Fine needle aspiration cytology (FNAC) of the thyroid has been a reliable and cost-effective method for diagnosing thyroid disorders. Since FNAC results are usually operator dependent, there is a compelling need to explore FNAC accuracy among Omanis.

Objective: Describe cytological features of FNAC and assess FNAC accuracy compared to the postsurgical histopathology report.

Transplant Associated Graft versus Host Disease.

Graft versus host disease (GVHD) occurs quite often after hematopoietic cell transplantation. However, it is a rare complication after solid organ transplantation and consists of a reaction of donor-derived immune cells directed against host tissues, which is mostly seen in liver, small intestine, and pancreas transplantation. We are presenting a 54-year-old man with a long-standing history of hypertension, hypertensive nephrosclerosis, and stage V terminal chronic kidney disease, who was on a regular hemodialysis thrice weekly.

Congenital Vascular Malformations: A Quick Recap.

We present a glimpse of vascular malformations seen at Sultan Qaboos University Hospital from July 2014 to December 2019. The cases are sporadic in nature. Molecular genetic studies can be conducted in patients with a family history of vascular malformations.

Prevalence of Cytological Abnormalities in Papanicolaou Smears and Risk Factors for Cervical Cancer Among Women in Muscat, Oman.

Objectives: This study aimed to estimate the prevalence of cytological abnormalities in Papanicolaou (Pap) smears and related risk factors among Omani women.

Methods: A cross-sectional study was conducted from March to September 2019 at the gynaecology and family medicine clinics of Khoula Hospital and Sultan Qaboos University Hospital in Muscat. All asymptomatic Omani women aged between 21 and 65 years were included.

Disease-free Survival of Patients with Differentiated Thyroid Cancer: A Study from a Tertiary Center in Oman.

Objectives: As with global trends, the prevalence of differentiated thyroid cancer (DTC) has increased in recent years in Oman. However, to the best of our knowledge, no local studies have yet been published evaluating the prognosis of DTC cases in Oman. This study aimed to assess disease-free survival (DFS) and prognostic factors related to DTC among Omani patients attending a tertiary care center.

Impact of COVID-19 on vasooclusive crisis in patients with sickle cell anaemia.

Objectives: The study aimed to assess COVID-19 impact on the morbidity and mortality of vasooclusive crisis (VOC) in sickle cell anaemia (SCA) patients.

Methods: A prospective cohort study of 100 SCA patients; 50 with COVID-19 (COVID group) and 50 without (non-COVID group). All patients signed written informed consent.

PHACES Syndrome with Intestinal Hemangioma Causing Recurrent Intussusceptions: A Case Report and Literature Review of Associated Intestinal Hemangioma.

PHACES syndrome comprises osterior fossa malformations, segmental emangioma, rterial anomalies, ardiac defects, ye anomalies and less commonly, ternal cleft, or supraumbilical raphe. We report a case of PHACES syndrome associated with intestinal hemangioma causing recurrent intussusceptions. A full-term infant female presented at the age of three months with segmental distribution of telangiectatic patch with red swelling involving the right periorbital area, right forehead, and lips.

Ichthyosis prematurity syndrome in two Omani siblings, caused by homozygous c.1A > G mutation in the FATP4 gene.

Ichthyosis prematurity syndrome (IPS) is a rare type of syndromic autosomal recessive congenital ichthyosis (ARCI) caused by a mutation in the SLC27A4 gene that encodes the fatty acid transport protein 4 (FATP4), which is responsible for keratinocyte differentiation and skin barrier function. IPS is characterized by a triad of prematurity, perinatal respiratory asphyxia, and thick vernix caseosa-like scales. In this report, we present the clinical and molecular characterization of IPS in two Omani siblings.

Urticarial vasculitis in pediatric systemic lupus erythematosus.

Background/objectives: To determine the prevalence of urticarial vasculitis (UV) in a pediatric systemic lupus erythematosus (pSLE) cohort of Arab ethnicity from Oman and to describe their demographic, clinical, and laboratory features.

Methods: We conducted a retrospective multicenter study among pediatric rheumatology centers in Oman over a 10-year period from 2008 to 2018. Analyses were performed using univariate statistics.

Higher Levels of Cystatin C in HIV/AIDS Patients with Metabolic Syndrome.

Data about Cystatin-C levels in HIV-infected patients with metabolic syndrome (MetS) are still limited. Therefore, the aim of this study was to evaluate the possible correlations of serum levels of Cystatin-C in HIV/AIDS patients treated with combined antiretroviral therapy (cART) with or without MetS. This cross-sectional study included 89 HIV/AIDS Caucasian patients receiving cART at the HIV/AIDS Centre Belgrade, Serbia, divided into two groups according to the presence of MetS.
