OBJECTIVE: The aim of the study was to investigate the associations of cross-sectional area (CSA) of the median nerve measured by ultrasonography, the median to ulnar nerve ratio (MUR), the median to ulnar nerve difference (MUD) and the ratio of CSA of the median nerve to height squared (MHS) in relation to electrodiagnostic classification of moderate and severe carpal tunnel syndrome (CTS) and thus to identify patients suitable for surgical treatment. MATERIALS AND METHODS: A prospective study was conducted in patients aged ≥ 18 years who underwent both median and ulnar nerve ultrasonography and electrodiagnostic studies (EDS). 124 wrists of 62 patients were examined. The patients' characteristics were acquired through a questionnaire. CTS was diagnosed using EDS and classified according to the guidelines of the Czech Republic Association of Electrodiagnostic Medicine. The CSA of the median nerve and of the ulnar nerve were measured at the carpal tunnel inlet. RESULTS: Median nerve CSA at the tunnel inlet ≥ 12 mm2 correlates with electrodiagnostic classification of moderate to severe carpal tunnel syndrome. At this cut-off value, the sensitivity of ultrasonography is 82.4%, its specificity is 87.7%, the positive predictive value is 82.4%, the negative predictive value is 87.7%. MUD, MUR and MHS perform worse than the median nerve CSA, as shown by their lower area under the receiver operating characteristic curve. CONCLUSIONS: Ultrasound could help us indicate surgical treatment for CTS, especially in patients with clinical findings. Our results suggest a cut-off value of CSA at the tunnel inlet of ≥ 12mm2.

OBJECTIVES: The first objective of our study was to determine the radiation exposure received by patients during tin-filtrated ultra-low-dose computed tomography (TFULDCT) of sacroiliac joints and to compare those to conventional X-ray doses. For comparison, we added a cohort examined by low-dose CT (LDCT) without tin filtration. The second objective was to compare the results of TFULDCT and X-ray in the detection of sacroiliitis. METHODS: Our retrospective study covered 45 patients, who were examined for suspected axial spondyloarthritis (AxSpA). The first group underwent TFULDCT as well as conventional radiography (CR); the second group underwent LDCT only without tin filtration. Effective doses of TFULDCT, LDCT and CR were calculated by an experienced medical physicist. TFULDCT and CR were independently evaluated by three investigators, who decided on the presence or absence of rheumatoid inflammatory bone changes. The results were statistically evaluated. RESULTS: In our cohort, the median effective dose for TFULDCT was 0.11 mSv, range (0.06-0.40 mSv), for LDCT 0.5 mSv (0.29-0.89 mSv), and for CR 0.25 mSv (0.06-1.87 mSv). We proved that TFULDCT produces a significantly lower percentage of uncertain results (23.3%; 95% CI: 11.3-41.6%) than CR (66.7%; 95% CI: 48.3-81.1%). CONCLUSIONS: Tin filtration helps to reduce CT radiation exposure to values lower than those resulting from CR. TFULDCT offers better overall diagnostic performance than CR. Our results prove that TFULDCT can replace CR in the diagnosis of sacroiliitis in the radiographical stage of AxSpA.
Obstetric forceps were invented in the 1600s to assist vaginal delivery of term babies following prolonged labour. This probably explains their design, with a narrow interblade distance and long blade length, to fit a severely moulded fetal head. However, in modern obstetric practice protracted labour is avoided, yet our research has shown that over 400 years forceps dimensions have remained largely unchanged. We believe it is time to optimise these dimensions based on biometry of the term, newborn baby's head, with the head width (biparietal diameter) and head length (mentovertical diameter) correlating with interblade distance and blade length respectively. We hypothesise that doing so should reduce the incidence of neonatal complications associated with forceps assisted delivery and it is also possible that the amended shape might be associated with better outcomes for women. In this article we present our rationale for the optimisation of the forceps dimensions based on the findings of our previous systematic review and an original series of mentovertical and biparietal diameter measurements using laser scanning technology.

Accumulating evidence indicates that immune checkpoint inhibitors (ICIs) can restore CD8+ cytotoxic T lymphocyte (CTL) functions in preclinical models of acute myeloid leukemia (AML). However, ICIs targeting programmed cell death 1 (PDCD1, best known as PD-1) and cytotoxic T lymphocyte-associated protein 4 (CTLA4) have limited clinical efficacy in patients with AML. Natural killer (NK) cells are central players in AML-targeting immune responses. However, little is known on the relationship between co-inhibitory receptors expressed by NK cells and the ability of the latter to control AML. Here, we show that hepatitis A virus cellular receptor 2 (HAVCR2, best known as TIM-3) is highly expressed by NK cells from AML patients, correlating with improved functional licensing and superior effector functions. Altogether, our data indicate that NK cell frequency as well as TIM-3 expression levels constitute prognostically relevant biomarkers of active immunity against AML.

STUDY OBJECTIVES: The primary aim of this study was to assess the clinical feasibility of a policy where laparoscopic sacrocolpopexy (LSC) is the default procedure for the management of a significant apical pelvic organ prolapse (a-POP). As a secondary aim, we wanted to evaluate LSC outcomes in relation to women's preoperative assessment of their surgical fitness using the American Society of Anesthesiologists physical status (ASA-PS) categorization. DESIGN: Retrospective cohort study. SETTING: A university affiliated urogynecology center. METHODS: All women with symptomatic a-POP (C ≥ -1) who attended the urogynecology clinic between the 1st of January and the 31st of December 2016 and had their surgery by the 31st of May 2017 were included in the study. In our unit, routine follow-up appointments are arranged at 3 and 12 months post LSC. INTERVENTIONS: Perioperative and mesh-related complications were assessed based on the Dindo-Clavien and IUGA/ICS classifications respectively. The preoperative outcome measures included Pelvic Organ Prolapse Quantification (POP-Q) stage, Pelvic Floor Distress Inventory (PFDI) and ASA-PS score. At follow-up women were asked to complete a PFDI, Patient Global Impression of Improvement (PGI-I), had their POP-Q staging and ultrasonographic assessment of mesh position and placement. The above measures are routinely collected as part of our standard practice. A preoperative ASA-PS score of <3 was used as a cut-off to dichotomies participants into low and high risk. MAIN RESULTS: A total of 220 women attended our center during the study period because of POP. Of these, 146 women were diagnosed with a significant a-POP and 142 (97.2 %) women opted for a surgical repair. Of the 142 women, 128 (90.1 %) were deemed suitable for a type of LSC and 121 had their surgery before the 31st of May 2017. There were no statistically significant differences in any of our collected perioperative, clinical, patient reported or ultrasonographic outcome measures when comparing women with ASA-PS scores of <3 or ≥3. CONCLUSION: In a specialized urogynecology healthcare setting, it is feasible and safe to rely on LSC as the mainstay surgical procedure for the repair of a significant a-POP. However, it is imperative to ensure that technical skills and equipment requirements are fulfilled and maintained.

Neuronal intranuclear inclusion disease (NIID) is a progressive neurodegenerative disorder categorized into 3 phenotypic variants: infantile, juvenile, and adult. Four recent reports have linked NIID to CGG expansions in the NOTCH2NLC gene in adult NIID (aNIID) and several juvenile patients. Infantile NIID (iNIID) is an extremely rare neuropediatric condition. We present a 7-year-old male patient with severe progressive neurodegenerative disease that included cerebellar symptoms with cerebellar atrophy on brain MRI, psychomotor developmental regression, pseudobulbar syndrome, and polyneuropathy. The diagnosis of iNIID was established through a postmortem neuropathology work-up. We performed long-read sequencing of the critical NOTCH2NLC repeat motif and found no expansion in the patient. We also re-evaluated an antemortem skin biopsy that was collected when the patient was 2 years and 8 months old and did not identify the intranuclear inclusions. In our report, we highlight that the 2 methods (skin biopsy and CGG expansion testing in NOTCH2NLC) used to identify aNIID patients may provide negative results in iNIID patients.
