We identified 6 additional glia originating bang-sensitive seizure lines and found upregulation of GSTs in 4 out of these 6 lines. These data suggest GST upregulation is common among gliopathic seizures and may ultimately provide insight for treating epilepsy. Mitochondrial ribosomal protein large 24 (MRPL24) is 1 of the 82 protein components of mitochondrial ribosomes, playing an essential role in the mitochondrial translation process. We report here on a baby girl with cerebellar atrophy, choreoathetosis of limbs and face, intellectual disability and a combined defect of complexes I and IV in muscle biopsy, caused by a homozygous missense mutation identified in MRPL24. The variant predicts a Leu91Pro substitution at an evolutionarily conserved site. Using human mutant cells and the zebrafish model, we demonstrated the pathological role of the identified variant. In fact, in fibroblasts we observed a significant reduction of MRPL24 protein and of mitochondrial respiratory chain complex I and IV subunits, as well a markedly reduced synthesis of the mtDNA-encoded peptides. In zebrafish we demonstrated that the orthologue gene is expressed in metabolically active tissues, and that gene knockdown induced locomotion impairment, structural defects and low ATP production. The motor phenotype was complemented by human WT but not mutant cRNA. Moreover, sucrose density gradient fractionation showed perturbed assembly of large subunit mitoribosomal proteins, suggesting that the mutation leads to a conformational change in MRPL24, which is expected to cause an aberrant interaction of the protein with other components of the 39S mitoribosomal subunit. BACKGROUND & AIMS Little is known about the natural history of childhood recurrent abdominal pain (RAP). We investigated the prevalence and progression of childhood RAP and its association with Rome III abdominal pain-related functional gastrointestinal disorders (AP-FGID) and irritable bowel syndrome (IBS) during adolescence. selleck products METHODS We collected data from a prospective population-based birth cohort study of 4089 children, born from 1994 through 1996 in Sweden. We analyzed data from 2455 children with complete follow up at ages 1, 2, 12, and 16 years and no parent-reported diagnoses of inflammatory bowel diseases or celiac disease at ages 12 or 16 years. A subpopulation of 2374 children who had answered questions based on the Rome III criteria at age 16 years was identified. We assessed RAP at 3 assessment points and defined it as parent-reported attacks of colic in early childhood (1-2 years) and self-reported weekly abdominal pain at ages 12 years and 16 years. Abdominal pain-related functional gastrointestinal disorder at age 16 years was defined according to the Rome III criteria. RESULTS RAP was reported by 26.2% of children on at least 1 of 3 assessment points, of which 11.3% reported symptoms more than once. Children with RAP at 12 years had persistent symptoms at 16 years in 44.9% of cases and increased risks for RAP (relative risk [RR], 2.2; 95% CI, 1.7-2.8), any AP-FGID (RR, 2.6; 95% CI, 1.9-3.6), and IBS (RR, 3.2; 95% CI, 2.0-5.1) at 16 years. Early childhood RAP was not significantly associated with any outcome. CONCLUSIONS RAP affects many children from early childhood through age 16 years, but most children do not have persistent symptoms throughout childhood. RAP at age 12 years is a risk factor for RAP, any Rome III AP-FGID and IBS, at age 16 years. In recent years, technological advances in sequencing have accelerated our understanding of epigenetics in ocular development and ophthalmic diseases. We now know that epigenetic modifications are necessary for normal ocular development and biological processes such as corneal wound healing and ocular surface repair, while aberrant epigenetic regulation underlies the pathogenesis of a wide range of ocular diseases, including cataracts and various diseases of the ocular surface. As the epigenetics of the eye is a constantly changing field of medicine, this comprehensive review focuses on innovations and scientific discoveries related to epigenetic control of anterior segment diseases that were published in the English literature in the past five years. These recent studies attempt to elucidate therapeutic targets for the anterior segment pathological processes. Already, recent studies have shown therapeutic potential in targeting epigenetic mechanisms of ocular disease, and new epigenetic therapies are on the verge of being introduced to clinical practice. New drug targets can potentially emerge as we make further discoveries within this field. Cancer is a global health problem and is one of the leading causes of death worldwide. Pleasingly, the rate of survival has improved and continues in an upward trend mainly due to better diagnosis and treatment modalities. In particular, the development of anticancer drugs including cytotoxic chemotherapy, hormonal agents and targeted therapies have provided the most effective treatment options in combatting cancerous cells. However, the antineoplastic mechanisms of these drugs can also lead to undesirable systemic and ocular side effects resulting from cytotoxicity, inflammation and neurotoxicity. While survival rates are projected to increase with time, the number of patients presenting with these side effects that can substantially impact quality of life will also rise. The current paper reviews the ocular surface and adnexal side effects of anticancer drugs, the appropriate management and possible interactions between drugs for ocular surface pathology treatment and the anticancer drugs. PURPOSE To visualize and quantify vascular networks in individuals with ocular surface squamous neoplasia (OSSN) through optical coherence tomography angiography (OCTA). METHOD Cross-sectional study of OSSN patients. Vascular networks were measured by OCTA in the epithelium and sub-epithelial space in the tumors, adjacent tissue, and in the contralateral eye. Vessel area density (VAD, percent of blood vessels within 2.14 mm2), was calculated for each location. Total tumor density (TTD, percent of blood vessels within the entire tumor) was calculated. VAD was assessed separately for corneal and conjunctival locations and compared. RESULTS Fifteen patients with OSSN were included. The mean age was 61 ± 12 years and the majority were male (80%). The mean tumor area, volume, depth, VAD, and TTD were 28.6 ± 8.1 mm2 (range, 14.1-39.0), 9.1 ± 4.2 mm3 (range, 3.4-18.8), 317 ± 107 μm (range, 177-570), and 32.2% ± 11.7% (range, 18.3-58.8), respectively. The VAD was highest under the conjunctival component of tumor (42.6% ± 9.6%) followed by within the conjunctival tumor (32.8% ± 8.3%). These densities were higher than the VADs measured in all other tissues (all P  less then  0.01). The VAD within conjunctival component of tumor was significantly higher than those with corneal component (33.5% ± 9.6% vs. 26.8% ± 6.1%, p = 0.046). The VAD under conjunctival tumor was also significantly higher than under corneal component (46.4% ± 8.6% vs. 35.2% ± 5.6%, p = 0.001). CONCLUSIONS OCTA imaging allowed for visualization and quantification of vessel structure and density within, under, and surrounding OSSN. Fasciola hepatica is a common parasite of livestock in Ireland, causing significant economic losses and affecting animal welfare. A previous abattoir study of 200 horses led to an estimated 9.5 % prevalence of infection in horses slaughtered in Ireland. However, the epidemiology and pathogenic significance of this infection in this species is not well-described. The objectives of this study were to determine the susceptibility of horses to oral challenge infection with F. hepatica metacercariae, and to document the course of the infection along with serological and biochemical response. We attempted an experimental infection of horses (n = 10; 9 geldings and 1 mare) with F. hepatica. Four were given 1000 metacercariae, four 500 metacercariae and two were sham-infected. Blood and faecal samples were taken at intervals up to 18 weeks post-infection (wpi). ELISA assays were used to assess sero-conversion in the experimental horses and also in a panel of sera from horses of known fluke status. No flukes were recovered from any of the livers, and neither were any lesions that could be attributed to F. hepatica infection observed. Coproantigen ELISA was negative throughout for all horses. Three antibody detection ELISAs, useful in diagnosing fasciolosis in other species, had limitations as diagnostic aids as determined using a panel of sera from horses of known F. hepatica infection status. This study is limited by the relatively small number of animals included, and the relatively short duration of the study period. Failure to establish infection after oral challenge raises fundamental questions on the pathophysiology and epidemiology of equine fasciolosis. A 76-year-old male whose brain MRI demonstrated an anterior right frontal broad dural based homogenously enhancing mass measuring 6.0x3.1x6.3cm. after presenting with a one year progressive cognitive dysfunction. A right sided pterional craniotomy and resection of mass was performed under general anesthesia with an uncomplicated intraoperative course. Postoperatively, the right eye was noted to have an afferent pupillary defect, complete ophthalmoplegia, ptosis, and significant resistance to retropulsion. Emergent ophthalmologic consultation confirmed the ocular exam and the diagnosis of right orbital compartment syndrome was suspected. A right lateral canthotomy and cantholysis was performed by the ophthalmologist at the bedside. The fundoscopic retinal evaluation was normal. Non-contrast CT of the head demonstrated expected postoperative changes and mild edema of the right frontal lobe without evidence of acute hemorrhage. There was no retro-orbital hematoma but the right extra-ocular muscles appeared edematous compared to the left. No light perception and opthalmoplegia continued in the right eye. This case demonstrates that although very rare, orbital compartment syndrome can occur without compression of the eye or an intra-orbital mass. Visual loss is a devastating complication and preoperative informed consent of this complication is imperative. Constant vigilance to ensure adequate arterial and venous supply to the orbit, with great care to prevent external compression on the eye, hopefully, will continue to make this complication rare. The management of patients with novel coronavirus 2019 (COVID-19) represents a new challenge for medical and surgical teams. Each operating room in the world should be prepared thoughtfully, and the development of a protocol and patient route seems mandatory. An adequate degree of protection must be used. We propose recommendations to help different professionals in the establishment of protocols for the management of patients with COVID-19. We also offer a checklist that could be used in the operating room. BACKGROUND Spinal vascular malformations (SVM) are rarely multiple less than 50 observations have so far been documented, with a maximum of 4 coexisting lesions per patient, always restricted to a single vertebral region (e.g., cervical or thoracic). CASE DESCRIPTION We describe the case of a 61-year-old woman with Cowden syndrome (CS) with 15 spinal arteriovenous fistulas (AVFs) at the cervical, thoracic and lumbar levels and an adrenal AVF. She was initially referred for re-evaluation of an upper cervical spinal epidural spinal arteriovenous fistulas (SEAVF) diagnosed 6 years earlier. Her history included breast carcinoma, a malignant salivary gland tumor, and removal of multiple ovarian, thyroid, and gastric hamartomas. CT and MRI confirmed the presence of a prominent cervical vascular lesion. Spinal digital subtraction angiography (SpDSA) revealed the presence of 15 additional vascular anomalies. CONCLUSION This multiplicity of AVFs appears to result from a combination of various factors, including local regional hemodynamic changes, growth factor-mediated alterations involving notably VEGF pathways, and the prothrombotic state associated with abnormalities in blood vessel structure.
