UWS rates were significantly lower in pSS patients than in the control group. No association was identified between UWS and focus score (FS) ≥ 1 in LSGB. No differences were observed between anti-SSA-positive and anti-SSA-negative patients in terms of age, UWS rates, FS.

LSGB should be performed in all suspected pSS cases regardless of the UWS rate value, particularly in subjects without specific anti-SSA antibodies. In patients with suspected pSS, only less than one-half of the UWS measurements are below the value of 0.1mL/min adopted as the threshold in the classification criteria for pSS.

There are relatively limited data regarding renal impairment in SSc beyond SRC. We performed an electronic search using the key words systemic sclerosis or scleroderma combined with each of the following renal dysfunction, kidney, glomerular filtration rate (GFR), proteinuria and hematuria. We searched for reports relevant to renal dysfunction in SSc beyond SRC. In 796 SSc patients recruited in five studies. 251 (31.5%) had GFR  less then  90 ml/min whereas 155(19.5%) patients had GFR  less then  60 ml/min. Most data indicate that the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula should be considered as the most suitable tool for assessing renal function in SSc pts, since it provides similar results to measured GFR. These data indicate that renal dysfunction in SSc in not uncommon and therefore patients with SSc should have their renal function assessed by GFR estimation on a regular basis.
During pandemic, admissions for surgical emergencies dropped down dramatically. Also acute appendicitis decreased. The aim of the present study was to evaluate the change in volume and clinical presentation of patients with acute appendicitis during pandemic and the variation in treatment.

This is a retrospective study of patients admitted in 11 Italian hospital for acute appendicitis during the lockdown period (March-April 2020) compared with the same period of the previous 2years (2018-2019). The number and the rate of complicated and non-complicated acute appendicitis were recorded and compared between the two study periods; non-operative vs operative treatment and negative appendectomy rate were also recorded.

The study included 532 patients, 112 in the study period and 420 in the control period; Hospital admission for acute appendicitis dropped by 46% (OR 0.516 95% CI 0.411-0.648 p < 0.001) during the 2020 lockdown. The number of complicated acute appendicitis did not change (- 18%, OR 0.763 95% CI 0.517-1.124 p = 0.1719), whereas the number of non-complicated acute appendicitis significantly decreased (- 56%, OR 0.424 95% CI 0.319-0.564 p < 0.001). Non-operative treatment rate remained similar (12.1% vs. 11.6% p = 0.434). The negative appendectomy rate also significantly decreased (6.1% vs. 17.3%, p = 0.006).

The present study found a significant reduction of both admissions for non-complicated acute appendicitis and negative appendectomy rate during the pandemic period. Conversely, admissions for complicated acute appendicitis did not change.

NCT04649996.Toll-like receptors (TLRs) play critical role in the innate recognition of pathogens besides orchestrating innate and adaptive immune responses. These receptors exhibit exquisite specificity for different pathogens or their products and, through a complex network of signalling, generate appropriate immune responses. TLRs induce both pro- and anti-inflammatory signals depending on interactions with the adapter molecules thereby impacting the outcome of infection. Hence, TLR signalling ought to be stringently regulated to avoid harmful effects on the host. Mycobacteria express antigens which are sensed by TLRs leading to activation of various signalling molecules important for initiating the death of infected cells and containment of pathogens. Conversely, it also utilizes TLRs for immune evasion and persistence. Due to the enormous diversity in the repertoire of virulence traits expressed by mycobacteria, genetic variations in TLRs often impair the host's ability to respond to mycobacterial-stress, affecting health and disease manifestations. Thus, understanding TLR signalling is of great importance for insights into host-mycobacterial interactions and designing effective measures for controlling the spread and persistence of the bacterium.A cornerstone in the treatment of osteoarthritis in young patients is the evaluation and correction of the leg axis. The combination of a joint injury (meniscus, cartilage, ligament) and an axis deviation inevitably, depending on its extent and the patient's comorbidities such as obesity, leads to progressive osteoarthritis of the knee after a few years. In addition to the precise deformity analysis for osteotomy planning, it is important to know the normal ranges of the corresponding angles and to define a target value for axis correction. Reflecting the repertoire of different osteotomy options around the knee (open vs. IBMX price closed, tibial vs. femoral, medial vs. lateral), the side effects in relation to patellofemoral maltracking, ligamentary balancing and leg length should then be assessed. Especially with regard to possible (and probable) prosthetic operations at some time in the future of young patients, new bony deformities or ligamentous insufficiencies, which potentially arise from overcorrection, must be avoided.Regarding the importance of ligament replacement in existing osteoarthritis three topics are highlighted the development of osteoarthritis after ACL-tear or -replacement, ACL-replacement in existing osteoarthritis and ACL-replacement together with medial unicompartmental knee replacement. Concomitant lesions at the meniscus and cartilage, especially the patella-femoral cartilage are risk factors for the development and progression of osteoarthritis in ACL insufficiency. The treatment of a symptomatic ACL-insufficiency in existing osteoarthritis in the elderly patient is directly dependent on pre-existing degenerative changes. Medial unicompartmental knee replacement and ACL-replacement can, however, be well combined and lead to very good long-term results even in the young patient.
