Heerfordt syndrome with unilateral facial nerve palsy: a rare presentation of sarcoidosis.

BACKGROUND: Heerfordt syndrome is rare and is characterized by fever, uveitis, parotid gland enlargement, and facial nerve palsy. We hereby present a case of Heerfordt syndrome with unilateral facial nerve palsy as a presentation of sarcoidosis. HISTORY AND SIGNS: A 29-year-old male patient from Sri Lanka presented with eye redness OU, blurred vision OD, fever, headache, night sweat, fatigue, and weight loss (5 kg over 1 month). Examination revealed mild anterior uveitis OU, mild vitritis OD, fundus whitish lesions OU, left otalgia, taste disorders, bilateral parotid gland enlargement, and left facial nerve palsy. Work-up for infection or tumour was negative. Chest computed tomography and transbronchial lymph node biopsy set the diagnosis of sarcoidosis. THERAPY AND OUTCOME: The patient recovered completely within 2 months under therapy with prednisone and azathioprine. One year after onset of treatment, no recurrence was noted. CONCLUSIONS: Heerfordt syndrome is a rare manifestation of neurosarcoidosis and has to be included in the differential diagnosis of facial nerve palsy.

Deviant trajectories of cortical maturation in 22q11.2 deletion syndrome (22q11DS): a cross-sectional and longitudinal study.

22q11.2 deletion syndrome (22q11DS) is associated with an increased susceptibility to develop schizophrenia. Despite a large body of literature documenting abnormal brain structure in 22q11DS, cerebral changes associated with brain maturation in 22q11DS remained largely unexplored. To map cortical maturation from childhood to adulthood in 22q11.2 deletion syndrome, we used cerebral MRI from 59 patients with 22q11DS, aged 6 to 40, and 80 typically developing controls; three year follow-up assessments were also available for 32 patients and 31 matched controls. Cross-sectional cortical thickness trajectories during childhood and adolescence were approximated in age bins. Repeated-measures were also conducted with the longitudinal data. Within the group of patients with 22q11DS, exploratory measures of cortical thickness differences related to COMT polymorphism, IQ, and schizophrenia were also conducted. We observed deviant trajectories of cortical thickness changes with age in patients with 22q11DS. In affected preadolescents, larger prefrontal thickness was observed compared to age-matched controls. Afterward, we observed greater cortical loss in 22q11DS with a convergence of cortical thickness values by the end of adolescence. No compelling evidence for an effect of COMT polymorphism on cortical maturation was observed. Within 22q11DS, significant differences in cortical thickness were related to cognitive level in children and adolescents, and to schizophrenia in adults. Deviant trajectories of cortical thickness from childhood to adulthood provide strong in vivo cues for a defect in the programmed synaptic elimination, which in turn may explain the susceptibility of patients with 22q11DS to develop psychosis.

Hepato-atrial anastomosis, the "other Senning operation" for treatment of Budd-Chiari syndrome.

A now 36-year-old woman developed a suprahepatic inferior vena cava stenosis, 9 years after liver transplantation for extensive liver echinococcosis. The lesion was treated by percutaneous angioplasty and stenting. Five years later, recurrence of echinococosis with intrastent stenosis together with clinical symptoms, prompted surgical treatment. Hepato-atrial anastomosis was performed under cardiopulmonary bypass with good result.

Lack of the mitochondrial protein acylglycerol kinase causes Sengers syndrome.

Exome sequencing of an individual with congenital cataracts, hypertrophic cardiomyopathy, skeletal myopathy, and lactic acidosis, all typical symptoms of Sengers syndrome, discovered two nonsense mutations in the gene encoding mitochondrial acylglycerol kinase (AGK). Mutation screening of AGK in further individuals with congenital cataracts and cardiomyopathy identified numerous loss-of-function mutations in an additional eight families, confirming the causal nature of AGK deficiency in Sengers syndrome. The loss of AGK led to a decrease of the adenine nucleotide translocator in the inner mitochondrial membrane in muscle, consistent with a role of AGK in driving the assembly of the translocator as a result of its effects on phospholipid metabolism in mitochondria.
