In recent years, there has been increasing research interest in improving diagnostic and management protocols in childhood arterial ischaemic stroke (AIS). However, childhood stroke comprises, in approximately equal parts, both arterial ischaemic and haemorrhagic stroke (HS).

Ketamine and magnesium sulphate showed synergic interaction in the tail-immersion test and additive interaction in the rat formalin test. Aim of study was to evaluate the influence of serotonergic and opioidergic system of this combination in the formalin test in rats.

Thoracic interfascial plane blocks are effective for post-mastectomy acute analgesia. However, their effects on chronic pain are uncertain. We randomly allocated 80 women equally to pectoral nerve-2 (PECS 2) block or serratus plane block. The pectoral nerve-2 block reduced the rate of moderate or severe chronic pain from 13/40 (33%) with the serratus plane block to 4/40 (10%), p = 0.03, adjusted odds ratio (95%CI) 0.23 (0.07-0.80), p = 0.02. The rates of pain-free women at six postoperative months were indeterminate, 10/40 (25%) after serratus plane block vs. 19/40 (48%) after pectoral nerve-2 block, p = 0.06, adjusted odds ratio (95%CI) 2.9 (1.1-7.5), p = 0.03. Health-related quality of life at six postoperative months was similar after serratus plane and pectoral nerve-2 blocks, mean (SD) EQ-5D-3L scores 0.87 (0.15) vs. 0.91 (0.14), respectively, p = 0.21. The pectoral nerve-2 block reduced median (IQR [range]) morphine consumption in the first 24 postoperative hours from 6 (3-9 [1-25]) mg to 4 (2-7 [0-37]) mg, p = 0.04. However, acute pain scores after serratus plane and pectoral nerve-2 blocks were similar, median (IQR [range]) 23 (11-35 [0-70]) mm vs. 18 (11-27 [0-61]) mm, respectively, p = 0.44. Pectoral nerve-2 block reduced chronic pain 6 months after mastectomy compared with serratus plane block.

The efficacy of an ultrasound guided transmuscular quadratus lumborum block (QLB) for perioperative analgesia of the upper and lower abdomen remain debatable. The purpose of this study was to compare the cutaneous sensory blocked area (CSBA) between QLB blocks performed at the L2 vs. L4 levels.

A 52-year-old woman experienced severe headache, confusion, nausea, dizziness, and diplopia for three days. Magnetic resonance imaging of the brain showed multiple acute and subacute infarcts suggestive of embolic events. Dermatological examination was notable for splinter hemorrhages and macular patches on the fingernails and feet, respectively. Further diagnostic imaging of the chest and abdomen revealed pulmonary emboli and an ovarian mass with omental deposits and splenic infarcts. Fine needle aspiration cytology and surgery confirmed a diagnosis of high grade serous adenocarcinoma of the ovary with clear cell features. Extensive evaluation for malignancy should be considered on a case-by-case basis for patients with thromboembolic disease and an initial negative diagnostic evaluation for stroke. Consideration of patent foramen ovale closure is reasonable in patients with malignancy who are at risk for recurrent strokes.

A significantly higher proportion of patients with nonalcoholic steatohepatitis (NASH) who received obeticholic acid (OCA) had histological improvement relative to placebo in the FLINT (farnesoid X nuclear receptor ligand obeticholic acid for noncirrhotic, NASH treatment) trial. However, genetic predictors of response to OCA are unknown. We conducted a genome-wide association study (GWAS) in FLINT participants to identify variants associated with NASH resolution and fibrosis improvement. Genotyping was performed using the Omni2.5 content GWAS chip. To avoid false positives introduced by population stratification, we focused our GWAS on white participants. Six regions on chromosomes 1, 4, 6, 7, 15, and 17 had multiple single nucleotide polymorphisms (SNPs) with suggestive association ( < 1 ×  ) with NASH resolution. A sentinel SNP, rs75508464, near on chromosome 1 was associated with NASH resolution, improvement in the nonalcoholic fatty liver disease activity score, portal inflammation, and fibrosis. Among individuals carrying this allele, 83% achieved NASH resolution with OCA compared with only 33% with placebo. Eight regions on chromosomes 1, 2, 3, 11, 13, and 18 had multiple SNPs associated with fibrosis improvement; of these, rs12130403 near on chromosome 1 was also associated with improvement in NASH and portal inflammation, and rs4073431 near on chromosome 11 was associated with NASH resolution and improvement in steatosis. Multiple SNPs on chromosome 11 had suggestive association with pruritus, with rs1379650 near being the top SNP. We identified several variants that may be associated with histological improvement and pruritus in individuals with NASH receiving OCA. The rs75508464 variant near may have the most significant effect on NASH resolution in those receiving OCA.

Renal actinomycosis is a rare clinical infection, subacute to chronic presentation caused by the Actinomyces bacteria. Actinomyces israelii is diagnosed in the overpowering majority of reported cases. Abdominopelvic manifestation forms 10% to 20% of all actinomycosis, and may be misdiagnosed as either a malignancy or chronic inflammation due to the lower correct preoperative diagnostic rate (<10%).

Axial spinal pain generators are difficult to identify using current diagnostic modalities. Merging CT with SPECT (CT-SPECT) scans allows for accurate identification of areas with increased osteoblastic activity, which may reflect pain generators. In this study, the authors aimed to evaluate the degree of pain improvement in patients who underwent surgery, addressing primary pain generators identified by CT-SPECT.

Tumors located in the craniocervical junction region are significantly challenging for surgical resection. We shared our experience of a meningioma at craniocervical junction resected through far lateral approach in a 68-year-old female. The patient presented with intermittent headache with discomfort in the neck and shoulders for 3 years without any positive signs. Magnetic resonance imaging (MRI) revealed a tumor of 3.6 cm × 3.0 cm × 2.5 cm lying at the ventral side of medulla oblongata, with T1 hypointensity, T2 hyperintensity, and a significant enhancement on T1-contrast image. The far lateral approach on the right side was planned to resect the tumor with a park-bench position. The patient underwent a standard craniotomy using a lazy -shaped incision. The transposition of vertebral artery was performed carefully therein, followed by removal of part of the arches of atlas and axis. After exposure of the tumor, vertebral artery (VA) and posterior inferior cerebellar artery (PICA) adhesive to the lesion could be seen operatively. Truncating the supplying blood vessels of the tumor was taken as the first step, followed by resecting the tumor mass in a piecemeal manner. While preserving VA, PICA, posterior nerves, medulla oblongata, and cervical cord, gross-total resection was achieved under the careful operation. The patient tolerated the procedure well without any neurological deficits. Histological examination confirmed the tumor as a meningioma (World Health Organization [WHO] grade I). Postoperative MRI scan depicted complete resection of the tumor. The patient remained symptom free without any evidence of recurrence during the follow-up period of 1 year. Informed consent was obtained from the patient. The link to the video can be found at: https://youtu.be/i9H-wS4fF10 .
