Joubert syndrome (JS) is a rare, complex autosomal recessive inherited disorder mostly characterized by partial or complete agenesis of the cerebellar vermis. There is a wide clinical and genetic heterogeneity in the syndrome. The main clinical features of JS are hypotonia, ataxia, developmental delay, oculomotor apraxia, breathing abnormalities and peculiar neuroimaging findings. ⋯ NK cell deficiency might be associated with JS when there are additional features such as recurrent infections and tumors. NK cell deficiency may be part of the clinical spectrum of JS. Reduced cellular immunity in association with NK cell deficiency may be a feature in a subset of JS patients, especially if there is a history of recurrent infections, tumors and autoimmune disorders.

It has been suggested that the elastin gene is a candidate gene for the development of intracranial aneurysms (IAs). We investigated the association of single-nucleotide polymorphisms (SNPs) in the elastin gene in sporadic subarachnoid hemorrhage and in patients with unruptured aneurysms in China. ⋯ Furthermore, the minor allele of rs2071307 (allele A) was also associated with IA rupture; 31.3% of patients with ruptured IAs were carriers of the minor allele, whereas only 23.2% of patients with unruptured IAs carried the minor allele (odds ratio 1.51; 95% confidence interval, 1.09-2.10; p = 0.013). In conclusion, our study indicates that the elastin gene may be associated with the formation of IAs, and importantly, that it may also be associated with the rupture of IAs.

Transcutaneous electrical nerve stimulation (TENS) is defined as the application of an electrical current to the skin through surface electrodes for pain relief. Various theories have been proposed in order to explain the analgesic mechanism of TENS. Recent studies have demonstrated that part of this analgesia is mediated through neurotransmitters acting at peripheral sites. ⋯ However, LF TENS, but not HF TENS, completely reduced 5-HT-induced hyperalgesia. Pre-treatment of the paw with naltrexone, prior to application of TENS, (Nx: 50 μg; I.pl.) showed a complete blockade of the analgesic effect induced by low frequency TENS. Thus, our results confirmed the lack of an anti-inflammatory effect through the use of TENS as well as the participation of peripheral endogenous opioid receptors in LF TENS analgesia in addition to its central action.

Review Case Reports
A unilateral brachiocephalic vein thrombosis: cause of a rare, transient ischemic attack, a case report and review of the literature.
The purpose of this report is to inform medical professionals of a case in which brachiocephalic vein thrombosis caused a transient ischemic attack (TIA). A brain computerized tomography (CT) scan, magnetic resonance imaging, digital subtraction angiography, head and lung CT angiography, jugular venography, cardiac color Doppler ultrasound scan, color Doppler ultrasound scan of the neck and lower vascular extremities and 24-hour, continuous electrocardiogram monitoring were performed. A 50-year-old male experienced a total of 31 onsets of weakness in the right side of his body, speech impairment and numbness in the right side of his body during a period of 20 days. ⋯ On the following day after the termination of the TIA, a color Doppler ultrasound scan detected the opening of the jugular venous arch, but the blood flow that returned to the superior vena cava via the left brachiocephalic vein did not significantly increase. A brachiocephalic vein thrombosis can be the cause of a TIA. In addition to the anticoagulant and antiplatelet aggregation treatment, the opening of the collateral of veins, including that of the jugular venous arch, may play an important role in reducing venous congestion and in terminating TIAs.
