CDKN2A/B homozygous deletion in IDH-mutant astrocytoma is associated with shorter survival, similar to WHO grade 4. The T2-FLAIR mismatch, a highly specific but insensitive sign, is diagnostic of IDH-mutant astrocytoma. Maximal safe resection is currently indicated in all LGG cases. Radiotherapy with subsequent PCV (procarbazine, lomustine, vincristine) provides longer overall survival compared to radiotherapy alone. Temozolomide in place of PCV is reasonable, but high-level evidence is still lacking. LGG adjuvant treatment has important quality of life and neurocognitive side effects that should be considered. Although incurable, IDH-mutant LGG have a favorable survival compared to IDH-WT glioma. Recent advances in molecular-based classification, imaging, and targeted therapies will hopefully improve survival and quality of life.Mast cells (MC) are immune cells that produce a variety of mediators, such as proteases, that are important in the body's immune responses. MC proteases have pronounced multifunctionality and in many respects determine the biological characteristics of the organ-specific MC population. Although, increased numbers of MC are one of the objective mastocytosis signs, a detailed assessment of the proteases biogenesis and excretion mechanisms in the bone marrow (BM) has not yet been carried out. Here, we performed an analysis of the expression of proteases in patients with various forms of systemic mastocytosis. We presented data on intracellular protease co-localization in human BM MCs and discussed their implication in secretory pathways of MCs in the development of the disease. Systemic mastocytosis, depending on the course, is featured by the formation of definite profiles of specific proteases in various forms of atypical mast cells. Intragranular accumulation of tryptase, chymase and carboxypeptidases in the hypochromic phenotype of atypical mast cells is characterized. Characterization of MC proteases expression during mastocytosis can be used to refine the MC classification, help in a prognosis, and increase the effectiveness of targeted therapy.

Spinal diseases requiring urgent surgical treatment are rare during pregnancy. Evidence is sparse and data are only available in the form of case reports. Our aim is to provide a comprehensive guide for spinal surgery on pregnant patients and highlight diagnostic and therapeutic aspects.

The study included a cohort of consecutive pregnant patients who underwent spinal surgery at five high-volume neurosurgical centers between 2010 and 2017. Perioperative and perinatal clinical data were derived from medical records.

Twenty-four pregnant patients were included. Three underwent a preoperative cesarean section. Twenty-one patients underwent surgery during pregnancy. selleck inhibitor Median maternal age was 33years, and median gestational age was 13 completed weeks. Indications were lumbar disk prolapse (n = 14; including cauda equina, severe motor deficits or acute pain), unstable spine injuries (n = 4); intramedullary tumor with paraparesis (n = 1), infection (n = 1) and Schwann cell nerve root tumor presenting with high-grade paresis (n = 1). Two patients suffered transient gestational diabetes and 1 patient presented with vaginal bleeding without any signs of fetal complications. No miscarriages, stillbirths, or severe obstetric complications occurred until delivery. All patients improved neurologically after the surgery.

Spinal surgical procedures during pregnancy seem to be safe. The indication for surgery has to be very strict and surgical procedures during pregnancy should be reserved for emergency cases. For pregnant patients, the surgical strategy should be individually tailored to the mother and the fetus.

The goal of administering preoperative systemic prophylactic antibiotics is to have the concentration in the tissues at its optimum level at the start and throughout the surgery. The rationale for the use of antibiotics is not well accepted; possible side effects and development of microbial resistance patterns are potential risks along with the financial burden. Therefore, the present study was conducted with the aim to clinically evaluate the serum and tissue concentration of single-dose prophylactic ceftriaxone during an ongoing laparoscopic cholecystectomy (LC) and to find out risk factors for post operative surgical site infections (SSI).

It was an open labelled prospective study in 50 consecutive patients who underwent elective laparoscopic cholecystectomy under prophylactic cover of ceftriaxone. Serum and tissue concentration were estimated by HighPerformanceLiquidChromatography during the ongoing surgery. Subjects were observed for any post-operative complications including SSI.

Serum and tissue concentrations of ceftriaxone were significant at test value of 4milligrams/Litre. Body mass index was significantly correlated with the tissue concentration of ceftriaxone at the time of incision. The rate of SSI was 2%. It significantly correlated with age more than 60years, diabetes and infected bile.

A single prophylactic intra-venous dose of 1g ceftriaxone immediately prior to skin incision in LC is good enough for prevention of SSI in Indian patients.

Medical education has been disrupted by the COVID-19 pandemic in many countries, with face-to-face lectures replaced by pre-recorded videos. However, surgical skills training cannot be replaced easily by videos, as a high level of tutor-student interaction is required. Thus, we developed anew web-based surgical skill learning session (WSSL). This case-control study evaluates the surgical skills competency of medical students taught by the WSSL.

This case-control study compares WSSL with face-to-face tutorials. Students were assigned randomly to one of two groups according to the teaching method. Independent blinded assessment was performed by a standardized marking scheme, modified from the Objective Structured Assessment of Technical Skills (OSATS) global rating scale.

We recruited 62 final-year medical students into the study, with 33 randomized to the face-to-face teaching group (control group), and 29 to the WSSL group(case group) according to their student number. The baseline demographic characteristics of the two groups were comparable.
