Juvenile lupus-like with negative serology: a clinical dilemma and diagnostic challenge.

Systemic lupus erythematosus (SLE) is an autoimmune disorder that can affect various organs. Juvenile-onset SLE (jSLE) may be more severe than the adult-onset form, but the diagnosis and classification remain challenging due to the complex nature of the condition and its resemblance to other conditions. Antinuclear antibodies (ANA) are the immunological hallmark of SLE, but their limited specificity poses challenges.

The indications and safety of rituximab for the treatment of pediatric autoimmune diseases: a single-center retrospective study.

Background: Autoimmune diseases in children pose therapeutic challenges due to their refractory nature and the associated morbidity. Rituximab (RTX), a monoclonal antibody targeting CD20, has emerged as a promising steroid-sparing therapy for various autoimmune disorders by depleting B cells. However, its indications and safety in pediatric populations in our region remain insufficiently studied.

Sarcoidosis Presenting With Nephritis and Pancreatitis in a Pediatric Patient: A Rare Case.

Sarcoidosis is a multisystem granulomatous disorder of undetermined etiology that usually affects the lungs. It is a rare presentation to have an association between sarcoidosis and pancreatitis. We present a challenging case of acute pancreatitis and kidney dysfunction which had been diagnosed later to be sarcoidosis.

Utility of pan-immune-inflammation value as a predictor of the prognosis of childhood lupus.

Background: Systemic lupus erythematosus (SLE) is a chronic inflammatory multisystemic disease. Monitoring disease activity thoughtout the disease course is important for effective management and assessment of disease outcome.

Objective: To assess whether the pan-immune inflammation value (PIIV) at diagnosis could predict organ involvement and disease activity in childhood SLE (cSLE) patients after 12 months of disease onst.

Practice Patterns and Approach to Childhood Lupus Nephritis in Saudi Arabia.

Renal involvement of systemic lupus erythematosus needs aggressive treatment. Despite the development of multiple international guidelines, differences in practices exist. This study aimed to explore the current practices of pediatric rheumatologists and nephrologists for the diagnosis, management, and monitoring of lupus nephritis (LN) in Saudi Arabia through a survey.

More than meets the eye: rhino-orbital cerebral mucormycosis with diabetic ketoacidosis presenting as periorbital edema resulting in orbital exenteration and maxillectomy.

Mucormycosis is an invasive fungal infection that can cause acute clinical decompensation and death. The literature demonstrates case fatality rates around 50% with differential clinical courses contingent upon anatomical incursion. Rhino-orbital cerebral mucormycosis represents a rapidly hostile variant with poorer outcomes, warranting prompt recognition, workup, and intervention.

Siblings With Thrombocytopenia Found To Have a Pathogenic Variant in the NFkB1 Gene.

Immune thrombocytopenic purpura is one of the most common causes of low platelet count in the pediatric population. Secondary thrombocytopenia has a wide differential diagnosis in children, including rheumatological, hematological, and immunological etiologies. Underlying etiologies must be excluded if suspected before labeling the patient as primary thrombocytopenia.

Impact of the COVID-19 pandemic on the psychological status of undergraduate medical students in Saudi Arabia: A cross-sectional double-scale study.

The COVID-19 pandemic is a major health care catastrophe that affects people's physical and mental well-being worldwide. Medical students are at an increased risk of mental health hazards during the COVID-19 pandemic. Sulaiman Al Rajhi University (SRU), the site of our study, is located in Qassim province in the Kingdom of Saudi Arabia.

TNF-inhibitors or bisphosphonates in chronic nonbacterial osteomyelitis? - Results of an international retrospective multicenter study.

Chronic nonbacterial osteomyelitis (CNO) can cause significant morbidity, including bone pain and damage. In the absence of clinical trials, treatments include non-steroidal anti-inflammatory drugs, corticosteroids, TNF-inhibitors (TNFi) and/or bisphosphonates. In a retrospective chart review in the United Kingdom and Germany, we investigated response to TNFi and/or pamidronate.

Cardiovascular benefits from SGLT2 inhibition in type 2 diabetes mellitus patients is not impaired with phosphate flux related to pharmacotherapy.

The beneficial cardiorenal outcomes of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in patients with type 2 diabetes mellitus (T2DM) have been substantiated by multiple clinical trials, resulting in increased interest in the multifarious pathways by which their mechanisms act. The principal effect of SGLT2i (-flozin drugs) can be appreciated in their ability to block the SGLT2 protein within the kidneys, inhibiting glucose reabsorption, and causing an associated osmotic diuresis. This ameliorates plasma glucose elevations and the negative cardiorenal sequelae associated with the latter.

The Rothman Index Does Not Predict a Successful Extubation in the Neurosurgical Critical Care Unit.

Background Identification of risk factors associated with successful extubation in neurosurgical critical care units (NSICUs) has been elusive due to the complex nature of neurocritical care injuries and patient factors. Traditional risk factors for extubation were shown to have poor predictive value in neurocritical care patients as compared to mixed ICU patients. The aim of this study was to determine if any risk factors, including the Rothman Index, could reliably predict successful extubation in a large sample size of neurocritical care patients.

Correction to: A Rare Presentation of Omental Lymphangioma Masquerading as Malignancy in an Adult Patient.

[This corrects the article on p. e00491 in vol. 7, PMID: 33324710.

A Rare Presentation of Omental Lymphangioma Masquerading as Malignancy in an Adult Patient.

Abdominal lymphangiomas are benign vascular neoplasms of the lymphatic vessels. Most are believed to be congenital, and they rarely present in the abdomen in adults. Omental lymphangiomas, in particular, are especially rare and can masquerade as malignancy, which requires further invasive workup.

Cases and etiologies of suspected COVID-19 reactivation.

Our article outlines a perspective on COVID-19 reactivation with considerations of implored commentary on behalf of the medical community regarding open discourse about this subject. Such a topic is paramount in elucidating parameters that pertain to testing, and subsequent public health population dynamics once uneventful cases pass. We argue that what some may refer to as a reinfection or reactivation of the virus, is actually a result of prolonged shedding of the virus complemented with occasional false positives/negatives and lab errors.

The systemic implication of novel non-statin therapies in cardiovascular diabetology: PCSK9 as a case model.

PCSK9, like other novel non-statin drugs were primarily developed to help patients achieve low-density lipoprotein cholesterol targets, especially in patients with dyslipidemia not achieving lipid goals with statins due to poor tolerance or inadequate response. PCSK9 inhibitors, in addition to modulating lipid metabolism, improve mortality outcomes in cardiovascular disease. These benefits are markedly pronounced in patients with type 2 diabetes mellitus.

Neural tone and cardio-renal outcomes in patients with type 2 diabetes mellitus: a review of the literature with a focus on SGLT2 inhibitors.

Recent clinical trials involving the systemic effects of sodium-glucose cotransporter 2 inhibitors (SGLT2i) have revealed beneficial outcomes pertaining to the microvascular sequelae of type 2 diabetes mellitus (T2DM) such as nephropathy, as well as macrovascular effects such as major adverse cardiovascular effects (MACE). Such findings have spurred the elevation of these agents to level A-tiers of recommendation within clinical guidelines addressing the management of complicated T2DM. While the mechanisms of SGLTi (-flozin drugs) are still being elucidated, a paucity of data exists within the literature appraising the role of neuromodulation and associated mechanisms in the aforementioned outcome studies.

ST Elevation Myocardial Infarction as Presenting Feature of C-ANCA Vasculitis: A Case of a Diagnostic Dilemma.

Unlabelled: Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS). Although uncommon, it should be included in the differential diagnosis for middle-aged patients without elevated atherosclerotic vascular disease risk or a family history of cardiovascular disease. SCAD is associated with postpartum women; however, reports noting its association with autoimmune disease and vasculopathy in other populations have recently gained prominence.

Prosthetic mitral valve endocarditis.

endocarditis is a fatal source of valvular infection with a near 100 % mortality rate if pharmacotherapy and valve-replacement surgery are not initiated swiftly after diagnosis. Complicating its diagnosis is the low yield for growth on standard blood culture and time requirements for molecular diagnostic tools to return a result. endocarditis of the mitral valve presents as valvular vegetations that reduce the caliber of the mitral valve and can cause syncope as in the case of mitral stenosis with subsequent valve failure, left atrial enlargement, and prospective cardiovascular failure.

Beyond the myocardium? SGLT2 inhibitors target peripheral components of reduced oxygen flux in the diabetic patient with heart failure with preserved ejection fraction.

Recent cardiovascular outcome trials have highlighted the propensity of the antidiabetic agents, SGLT2 inhibitors (SGLT2is or -flozin drugs), to exert positive clinical outcomes in patients with cardiovascular disease at risk for major adverse cardiovascular events (MACEs). Of interest in cardiac diabetology is the physiological status of the patient with T2DM and heart failure with preserved ejection fraction (HFpEF), a well-examined association. Underlying this pathologic tandem are the effects that long-standing hyperglycemia has on the ability of the HFpEF heart to adequately deliver oxygen.
