A 54-year-old male presented with a sudden burning sensation during urination and left flank pain. Apart from having congenital facial palsy and malformation of the inner right ear that was linked to thalidomide embryopathy, the patient has always been in good health. Urine examination showed the presence of a urinary tract infection. An abdominal...

Intracranial dermoid cysts are uncommon occurrence. The intracranially located dermoid cyst arises from ectoderm, probably derived from cell nest included during the closure of neural tube. The commonest site of intracranial dermoid cyst is posterior fossa. The more common supratentorial tumours are located on skull base, frontal or temporal or sup...
Common presentation of atretic parietal cephalocele (APC) is mostly seen in infants and young children. And, it is a palpable midline parietal soft tissue mass which is thought to represent involuted true cephalocele (meningocele or encephalocele)connected to dura mater via a fibrous stalk. The incidence of intracranial anomalies have increased wit...

... Several spinal abnormalities have been associated with CRS. Among them, there are fibro lipoma, lipoma, diastematomyelia, syringomyelia, kyphosis, myelomeningocele used even in the guile's classification of CRS [14][15][16]. In our case, it has just been reported dorsal kyphosis as a spinal abnormality associated. ...
Lumbosacral agenesis is a rare and complex malformation characterized by a total or partial absence of the lumbosacral vertebrae. It is often associated with other congenital malformations. Its etiology is poorly understood but factors such as gestational diabetes, genetic abnormalities and environmental factors are incriminated. We report the case of a female infant, 11 months old, who presented with lumbosacral agenesis. As our hospital was less equipped to deal with this complex malformation, we transferred the infant to another better equipped hospital.
In this article, chiral templating of a polycarbonate (PC) membrane by (-)-α-pinene using the atomic layer deposition (ALD) approach is investigated. The templating with the enantiomer of (-)-α-pinene, used as a case compound, was performed either on the original commercial PC membrane or on the PC membrane with a beforehand deposited Al2O3 layer. The efficiency of the templating was assessed by a difference in the membrane ability to adsorb/absorb (-)-α-pinene, (+)-α-pinene, and their racemic mixture, using a very sensitive gas sorption analyzer. The results clearly show that the solution-diffusion mechanism rather than the sieving mechanism applied for adsorption/absorption of (-/+)-α-pinene enantiomers, which have the same size of the molecule. The PC membrane with the predeposited Al2O3 before the (-)-α-pinene templating shows significantly higher sorption of (-)-α-pinene compared to (+)-α-pinene and racemate, which clearly demonstrates the presence of a chiral recognition effect.
