Opsoclonus-myoclonus ataxia syndrome (OMAS), also known as Kinsbourne syndrome, is a rare disorder that presents with myoclonus, ataxia, abnormal eye movements, irritability, and sleep disruptions, often in young children. We report a case of an infant barely 6 months old, with no significant past medical history, who presented to the emergency department with tremors, jerking motions of the head and arms, and rapid eye movements. After an extensive workup, she was found to have a neuroblastoma, which was subsequently surgically removed via thoracotomy.

Objective: Addressing family psychosocial and mental health needs in the perinatal and early childhood period has a significant impact on long-term maternal and child health and is key to achieving health equity. We aimed to (1) describe and evaluate the role of an Early Childhood Community Health Worker (EC-CHW) to address psychosocial needs and improve psychosocial well-being for families in the perinatal period, and (2) examine factors associated with completion of goals.

Methods: An EC-CHW program was modeled after an existing hospital CHW program for children with special healthcare needs and chronic disease.

Elsberg syndrome is a typically infectious syndrome that may cause acute or subacute bilateral lumbosacral radiculitis and sometimes lower spinal cord myelitis. Patients often present with various neurological symptoms involving the lower extremities, including numbness, weakness, and urinary disturbances such as retention. A 9-year-old girl with no significant past medical history presented with altered mental status, fever, urinary retention, and anuria and was found to have encephalomyelitis.

Besides physical vulnerability, pregnant women are at increased risk of mental health problems such as anxiety, depression and post-traumatic stress disorder due to the consequences of social distancing.

Most microarray slides are manufactured or coated with a layer of poly(L-lysine) or with silanes with different chemical functional groups, for the attachment of nucleic acids on to their surfaces. The efficiency with which nucleic acids bind to these surfaces is not high, because they can be washed away, especially in the case of spotting oligonucleotides. In view of this, we have developed a method to increase the binding capacity and efficiency of hybridization of DNA on to derivatized glass surfaces.
