Baller-Gerold syndrome Craniosynostosis-radial aplasia syndrome

A new case of the Baller-Gerold syndrome is described in a 6¹/₂-year-old, black male who presented at birth with bilateral synostoses of the coronal and lambdoidal sutures, bilateral radial aplasia, vertebral anomalies and genito-urinary malformations. The parents and siblings were unaffected, and there was no history of consanguinity. A review of the history and physical findings in our patient and in the four other patients previously reported in the literature is provided, with a discussion on pathogenesis, prognosis and the possible autosomal recessive mode of inheritance of the syndrome.     

Macrophage activation syndrome, hemophagocytic syndrome

Macrophage activation syndrome MAS describes the clinical, biological and histological symptoms related to a probably T lymphocytes/NK cell driven stimulation of macrophages with the consequence of a hemophagocytosis involving numerous organs, preferentially bone marrow, explaining the other term of "hemophagocytic syndrome". Clinical symptoms include cytopenia, multiple organ dysfunction, fever unresponsive to antibiotics, fatigue and rash. Infections (bacteria, virus or parasites), lymphoproliferative disorders, cancers, systemic diseases are the most prevalent triggers or etiologies of M.A.S. Evidence of haemaphagocytosis is obtained in the majority of cases with bone marrow specimens. In some cases haemophagocytosis can spare the bone marrow with involvement confined to other tissues such as liver and spleen. Very high levels of ferritine seem to correlate well with the presence of haemophagocytosis and is a possible marker for an early diagnosis. Early treatment initiation is mandatory. Corticosteroids, cytostatic drugs such as etoposide, cyclosporine A, plasmapherese, intravenous immunoglobulins and anti TNFalpha are proposed but no randomized trials were published.     

Tethered cord syndrome in KBG syndrome

Tethered cord syndrome (TCS) is characterized by leg pain and weakness, bladder and bowel dysfunction, orthopedic malformations such as scoliosis, and motor deficits caused by the fixation of the spinal cord to surrounding tissues. TCS is surgically treatable and often found in conjunction with other syndromic conditions. KBG syndrome is caused by variants in the ANKRD11 gene and is characterized by short stature, developmental delay, macrodontia, and a triangular face. The current study explores the prevalence of TCS in pediatric KBG patients and their associated signs and symptoms. Patients with KBG were surveyed for signs and symptoms associated with TCS and asked if they had been diagnosed with the syndrome. We found a high proportion of patients diagnosed with (11%) or being investigated for TCS (24%), emphasizing the need to further characterize the comorbid syndromes. No signs or symptoms clearly emerged as indicative of TCS in KBG patients, but some the prevalence of some signs and symptoms varied by sex. Male KBG patients with diagnosed TCS were more likely to have coordination issues and global delay/brain fog than their female counterparts. Understanding the presentation of TCS in KBG patients is critical for timely diagnosis and treatment.     

Autosomal dominant syndrome resembling Coffin-Siris syndrome

Coffin-Siris syndrome is a multiple congenital anomaly/mental retardation syndrome with phenotypic variability [OMIM 135900]. The diagnosis is based solely on clinical findings, as there is currently no molecular, biochemical, or cytogenetic analysis available to confirm a diagnosis. Although typically described as an autosomal recessive disorder, autosomal dominant inheritance has also been infrequently reported. We describe a mother and her two daughters who all have features that resemble Coffin-Siris syndrome. However, this is not a completely convincing diagnosis given that hypertelorism is not a feature of Coffin-Siris syndrome and the family is relatively mildly affected. Yet, this family provides further evidence of an autosomal dominant mode of inheritance for a likely variant of Coffin-Siris syndrome (at least in some families). In addition, Sibling 1 had premature thelarche. She is the second reported individual within the spectrum of Coffin-Siris syndrome to have premature thelarche, indicating that it may be a rare clinical feature.     

A lethal syndrome resembling branchio-oculo facial syndrome

Branchio-oculo-facial syndrome, a recently delineated autosomal dominant condition, is characterized by branchial cleft sinuses, ocular anomalies, and unusual facial appearance. A patient with branchial cleft fistulae, microphthalmia, nasomaxillary dysplasia, in addition to cardiac and CNS malformation (holoprosencephaly and meningo-encephalocele), is described. Although many features of this lethal malformation complex resemble those seen in the branchio-oculo-facial syndrome, the complex may represent a new multiple malformation syndrome.     

Amygdaloid nucleus syndrome and dehumanization syndrome.

Through statistical tests 3 groups of impulsive-aggressive patients were studied: group 1, 100 individuals with temporal dysrhythmia; group 2, 18 individuals with temporal dysrhythmia submitted either to group analytical therapy or to psychoanalysis; group 3, 25 impulsive-aggressive individuals. Moreover the author differentiates between the amygdaloid nucleus and dehumanization syndromes, through psychoanalytical or psychiatric studies, and stresses the importance of the molding periods in relation to social factors (frustration-aggression-injustice). Amygdalotomy of the hippocampus was suggested in special cases.     

Fronto-ocular syndrome: newly recognized trigonocephaly syndrome

We describe an apparently unique disorder, Fronto-Ocular syndrome, present in a mother and her two daughters, and comprising trigonocephaly due to coronal and metopic craniosynostosis, ocular hypotelorism, ocular proptosis and ptosis, epicanthal folds, hypoplastic supraorbital ridges, elevated nasal bridge, thin philtrum, high-arched palate and a narrow bifrontal region. Both daughters have glabellar capillary hemangiomas, a congenital heart defect and mild developmental disabilities. Review of the literature failed to disclose any syndrome with similar findings. It is likely that this disorder represents an autosomal dominant condition, that arose as a new mutation in the mother. Mutational analysis of fibroblast growth factor receptor (FGFR) 1 and FGFR2 failed to identify the molecular basis of the disorder.
