Infections of the central nervous system in patients at risk are relatively uncommon when compared with pneumonia, bacteremia, and soft tissue infection. However, they carry serious morbidity and are frequently fatal. Each of the diverse conditions that can place a patient at risk for central nervous system infection is associated with a fairly predictable spectrum of etiologic organisms. Various forms of trauma (including blunt and penetrating injuries and neurosurgery, especially when a cerebrospinal fluid shunt is implanted) predispose to infection with common pathogenic bacteria. Defects of cellular immunity including congenital immune deficiencies, immunosuppressive drug therapy, leukemia, lymphoma, and the acquired immune deficiency syndrome are more likely to give rise to infection with a distinctive spectrum of opportunistic viruses, fungi, and protozoa. Other underlying conditions include sinus, ear, and mastoid infections, congenital
heart disease
, intrathoracic suppuration, endocarditis, and bacteremia,
hypogammaglobulinemia
, and complement deficiencies. Some preventive measures including vaccines, antibiotics, and surgical procedures are available. However, for many of these central nervous system infections, preventive measures are lacking or less effective than those for infections in other organs. In the future, opportunistic central nervous system infections will increase in frequency as the number of patients at risk continues to grow.

DiGeorge Syndrome is a congenital immunodeficiency characterized clinically by hypocalcemic tetany, congenital
heart disease
, unusual facies, and increased susceptibility to infection. Pathologically, the syndrome is marked by the abscence or hipoplasia of the thymus and parathyroid glands as well as cardiac or aortic arch abnormalities. Most patients show partial or complete T cell immunodeficiency and normal or near-normal B-cell immunity. A review is made on a clinical case of DiGeorge syndrome is presented. A 52 days old boy, was admitted through emergency. There was no familial evidence of alcoholism or immunodeficiency. He showed irritability due to hypocalcemia. The examination revealed facial and cardiovascular abnormalities and the immunological investigation revealed
hypogammaglobulinemia
, deficiency of the cell, CD4 and CD8 decreased and with inverted relation. Chest X ray showed cardiomegaly grade II, and no thymus was seen. The diagnosis of the complete DiGeorge syndrome was based on the abnormalities found.

Jacobsen syndrome is a rare contiguous gene syndrome caused by partial deletion of the long arm of chromosome 11. The typical clinical manifestations include physical growth retardation, mental retardation,facial dysmorphisms, congenital
heart disease
, thrombocytopenia, or pancytopenia. A Thai-Australian girl was born with multiple abnormalities. Typical features and her karyotype, 46, XX, del(ll) (q23-qter), confirmed Jacobson syndrome. She had many uncommon findings including upslanting palpebral fissures, tortuousity of retinal vessels and
hypogammaglobulinemia
. In addition, this case also presented with protein C deficiency, which has not been reported previously in Jacobsen syndrome. The patient was treated with phototherapy, intravenous antibiotic injection, and platelet transfusion in neonatal period. Cranioplasty was performed for prevention of the increased intracranial pressure at three months of age. Surgical correction for strabismus was in the treatment plan.

Background: To alert for the diagnosis of the 22q11.2 deletion syndrome (22q11.2DS) in patients with congenital
heart disease
(CHD). Objective: To describe the main CHDs, as well as phenotypic, metabolic and immunological findings in a series of 60 patients diagnosed with 22q11.2DS. Methods: The study included 60 patients with 22q11.2DS evaluated between 2007 and 2013 (M:F=1.3, age range 14 days to 20 years and 3 months) at a pediatric reference center for primary immunodeficiencies. The diagnosis was established by detection of the 22q11.2 microdeletion using FISH (n = 18) and/or MLPA (n = 42), in association with clinical and laboratory information. Associated CHDs, progression of phenotypic facial features, hypocalcemia and immunological changes were analyzed. Results: CHDs were detected in 77% of the patients and the most frequent type was tetralogy of Fallot (38.3%). Surgical correction of CHD was performed in 34 patients. Craniofacial dysmorphisms were detected in 41 patients: elongated face (60%) and/or elongated nose (53.3%), narrow palpebral fissure (50%), dysplastic, overfolded ears (48.3%), thin lips (41.6%), elongated fingers (38.3%) and short stature (36.6%). Hypocalcemia was detected in 64.2% and decreased parathyroid hormone (PTH) level in 25.9%. Decrease in total lymphocytes, CD4 and CD8 counts were present in 40%, 53.3% and 33.3%, respectively.
Hypogammaglobulinemia
was detected in one patient and decreased concentrations of immunoglobulin M (IgM) in two other patients. Conclusion: Suspicion for 22q11.2DS should be raised in all patients with CHD associated with hypocalcemia and/or facial dysmorphisms, considering that many of these changes may evolve with age. The 22q11.2 microdeletion should be confirmed by molecular testing in all patients.
