ORAI1 is the pore-forming subunit of the calcium release-activated calcium channel responsible for calcium influx into cells triggered by endoplasmic reticulum store depletion. We report here a patient with severe combined immunodeficiency and absent store-operated calcium entry due to a novel mutation in ORAI1 that results in the expression of a C-terminally truncated protein that abolishes ORAI1 binding to STIM1.

This study aimed to investigate cardiovascular abnormalities in children with OI in comparison to a control group.
Methods: This case-control study was conducted at the Sultan Qaboos University Hospital in Muscat, Oman, between May 2013 and August 2014.

In most asthmatic children, inhaled steroids can relieve and control the symptoms of asthma. Persistent wheezing and respiratory symptoms in young children despite appropriate treatment may indicate other diagnostic considerations. Delays in this diagnosis can result in unnecessary investigations, inappropriate treatment and further complications.

Toxic epidermal necrolysis (TEN), an uncommon but potentially life-threatening skin reaction, is frequently induced by drugs. The mucocutaneous reaction is characterised by bullous detachment of the epidermis and mucous membranes. We present a 9-month-old male with methylmalonic acidaemia, generalised hypotonia, and global developmental delay.

Incontinentia Pigmenti (IP), (OMIM # 308300), is a rare X-linked dominant condition. It is a multisystemic disease with neuroectodermal findings involving the skin, eyes, hair, nails, teeth, and central nervous system. It is usually lethal in males; the disease has variable expression in an affected female.

Methods: The data were collected at the Child Neurology Services of Sultan Qaboos University Hospital, Oman, from January 1993 to September 2006 from all children with psychomotor delay and epilepsy, who underwent brain imaging (mostly MRI). The MR imaging was used for the diagnosis of a neuronal migration anomaly.
Congenital nasal pyriform aperture stenosis (CNPAS) is a recently defined clinical entity that causes airway obstruction in the neonate as a result of narrowing of the nasal pyriform aperture. The pyriform aperture is the narrowest, most anterior portion of the nasal airway, and a slight decrease in its cross sectional area will significantly increase the nasal airway resistance. This entity should be kept in the differential diagnosis of any neonate or infant with signs and symptoms of upper air way obstruction.

This often presents as a floppy infant, and normal mental development. The creatine kinase is usually elevated with white matter abnormalities on brain imaging.

Spinal fluid changes like mild to moderate pleocytosis (most of the cells are lymphocytes and macrophages) and sometimes hemophagocytosis are seen in primary HLH but are not reported in secondary HLH. Here we report a case of a previously healthy 10 months old male infant who was diagnosed as familial HLH with evidence of CSF hemophagocytosis.

A peculiar feature of onset with hearing loss in a patient with multiple cranial nerve palsies and a positive family history suggests this diagnosis. In our family, an autosomal recessive mode of inheritance was seen.
