Cytomegalovirus is considered as one of the most common causes of congenital infections. Clinical signs of infection are present in newborns whose mothers were infected during pregnancy. Disease is most severe if mother were infected during the first trimester. Congenital cytomegalovirus infection causes damage of CNS (central nervous system) and the liver, atrophy of optical nerve and hearing retardation up to complete loss. The most severe and frequent damage is of CNS. Under our observation were 20 children of different ages, among them 8 newborns. Verification of cytomegalovirus infection was done by ELISA. Polymerase Chain Reaction (PCR) was also used for diagnostic reasons. Examination of CNS was performed by neurosonography, electroencephalography and computed tomography. Four from eight newborns died at the age of 6-8 weeks (in these cases the generalized form of infection with severe damage of CNS was present). In the rest patients treatment with specific anticytomegalovirus immunoglobulin together with syndrome therapy yielded positive effect. Lately moderate retardation of phychomotor development became apparent in all cases. 12 patients, who come to our clinic in the period from 2 months to 1.5 years of age, psychomotor retardation, micro or hydrocephaly, hyperkinesias, absentia (epileptica), convulsive syndrome and malignant hypertension were present. On tomograms intracranial calcificats and cysts, also atrophy of cerebrum and encephalomalacia was visible. Sensory hearing loss was apparent in two patients. The study showed the presence of severe and in most cases irreversible CNS damages in the cases of congenital cytomegalovirus infection.

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Bacterial Meningitis01:24

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
