Acquired von Willebrand syndrome (AVWS) is a rare, non-hereditary bleeding disorder related to heterogeneous medical conditions such as hematological malignancies and cardiovascular and autoimmune diseases. We describe the clinical course of a 62-year-old man with polycythemia vera who experienced post-traumatic knee and leg swelling due to hemarthrosis. He was treated at another center with low molecular weight heparin due to misdiagnosed deep vein thrombosis further exacerbating the ongoing bleeding. At our center, he was diagnosed with AVWS with reduced von Willebrand factor (VWF):GPIbR plasma activity and loss of high molecular weight multimers (HMWM). He was treated with compressive bandages with resolution. Five months later, on clinical recurrence of knee and leg swelling, knee ultrasound scan showed the presence of chronic synovitis and a hemorrhagic Baker's cyst with signs of rupture. The treatment consisted of chemical synovectomy with rifampicin and steroids preceded by systemic replacement therapy using plasma-derived factor VIII-VWF concentrate. At the end of the treatment cycle, our patient reported complete resolution of knee pain and restoration of joint range of motion and function. Ultrasound evaluation confirmed complete resolution of knee capsule distension and Baker's cyst. Hemarthrosis is an anecdotal presentation of AVWS and chemical synovectomy was successful in treating this complication. A multidisciplinary approach allowed an effective management of this rare complication.

We examined the possible sex and age differences in the proportion of experienced Coronavirus Disease 2019 (COVID-19) symptoms in unaware (previously) infected adults, and their uninfected counterparts, estimated by serostatus prior to vaccination, at the end of 2020 (Wuhan strain). A cross-sectional community-based study using a convenience sample of 10 001 adult inhabitants of a southern Dutch province, heavily affected by COVID-19, was conducted. Participants donated a blood sample to indicate past infection by serostatus (positive/negative). Experienced symptoms were assessed by questionnaire, before the availability of the serological test result. Only participants without confirmed SARS-CoV-2 infection were included ( = 9715, age range 18-90 years). The seroprevalence was comparable between men (17.3%) and women (18.0%), and participants aged 18-60 years (17.3%) and aged 60 years and older (18.6%). We showed sex and age differences in the proportion experienced symptoms by serostatus in a large cohort of both unaware (untested) seropositive compared with seronegative reference participants. Irritability only differed by serostatus in men (independent of age), while stomach ache, nausea and dizziness only differed by serostatus in women aged 60 years and older. Besides, the proportion of experiencing pain when breathing and headache differed by serostatus in men aged 18-60 years only. Our study highlights the importance of taking possible sex and age differences into account with respect to acute and long-term COVID-19 outcomes. Identifying symptom profiles for sex and age subgroups can contribute to timely identification of infection, gaining importance once governments currently move away from mass testing again.

Brick kilns constitute one of the major sources of environmental degradation in Pakistan. The present study was conducted to determine the soil quality and total suspended particulates (TSPs) around the brick kilns and assess the health effects on brick kiln workers. Four brick kilns were selected, two each at Sheikhupura and Pattoki city. The soil quality was assessed by analyzing pH, electrical conductivity, moisture content, nitrogen, phosphorus, potassium content, and heavy metal concentration while TSPs were measured by hand-held Microdust Pro Real time monitor. Average TSP concentration around brick kilns at Sheikhupura and Pattoki ranged between 1100 and 1200 µg/m and between 550 and 600 µg/m respectively which exceeded the Punjab Ambient Air Standards. The soil was slightly acidic (Sheikhupura: average pH = 6.41; Pattoki: average pH = 6.6) while all other analyzed parameters, except heavy metals, were lower than the required FAO Standards for good quality agriculture soil. Heavy metal accumulation in soil samples followed the general order zinc (Zn) > chromium (Cr) > nickel (Ni) > manganese (Mn) > cadmium (Cd) > copper (Cu). For assessment of occupational health and safety issues, all 440 brick kiln workers from the study areas were interviewed. Mostly, brick kiln workers suffered from chronic back pain (84%), skin issues (80.5%), dry cough (72.9%), common cold (46.1%), and shortness of breath (17.1%). The vulnerability risk varied with the nature of the work as workers engaged in brick baking were more vulnerable to respiratory issues than were those in molding task. The study concludes that brick kilns are a source of increased TSP, deteriorated surrounding soil quality, and impaired worker health. It is necessary to regulate these activities and implement requisite health and safety measures.

Plantar fasciitis is a common cause of heel pain, and the disorder is generally self-limiting after adequate conservative treatment. When conservative treatment is unsuccessful, surgical release is an effective treatment option. Here we report a case of iatrogenic plantar fascia rupture after surgical release for treatment of recalcitrant plantar fasciitis. Preoperative MRI revealed a 4.2 cm gap between the distal fascia stump and the calcaneal tuberosity in the sagittal view at 8 months post-injury. To circumvent the possibility of rupture site retear or poor tissue healing by direct repair, we used tendon allografting for the reconstruction of the chronic plantar fascia rupture. The patient gradually recovered after the surgery. Complications of plantar fascia rupture after surgical release is a potential risk but rarely observed. Chronic plantar fascia rupture with medial arch collapse is difficult to treat. We used a tendon allograft to reconstruct the plantar fascia, restoring its function and mechanical strength. After 5 years of follow-up, no complications were reported, and magnetic resonance imaging indicated the reconstructed plantar fascia tissue to be in good condition.

The Rome IV includes a redefinition of functional gastrointestinal disorders and diagnostic criteria. The present study aimed to compare the Rome III and Rome IV classification results and to reveal their differences in children with chronic abdominal pain.

Cortical spreading depression (CSD) is a pathophysiological mechanism underlying headache disorders, including migraine. Blood-brain barrier (BBB) permeability is increased during CSD. Recent papers have suggested that heat shock proteins (HSP) contribute to the integrity of the blood-brain barrier. In this study, the possible role of HSP90 in CSD-associated blood-brain barrier leak at the endothelial cell was investigated using an in vitro model, for the blood-endothelial barrier (BEB), and an in vivo model with an intact BBB. We measured barrier integrity using trans endothelial electric resistance (TEER) across a monolayer of rodent brain endothelial cells (bEnd.3), a sucrose uptake assay, and in situ brain perfusion using female Sprague Dawley rats. CSD was induced by application of 60 mM KCl for 5 min in in vitro experiments or cortical injection of KCl (1 M, 0.5 µL) through a dural cannula in vivo. HSP90 was selectively blocked by 17-AAG. Our data showed that preincubation with 17-AAG (1 µM) prevented the reduction of TEER values caused by the KCl pulse on the monolayer of bEnd.3 cells. The elevated uptake of C-sucrose across the same endothelial monolayer induced by the KCl pulse was significantly reduced after preincubation with HSP90 inhibitor. Pre-exposure to 17-AAG significantly mitigated the transient BBB leak after CSD induced by cortical KCl injection as determined by in situ brain perfusion in female rats. Our results demonstrated that inhibition of HSP90 with the selective agent 17-AAG reduced CSD-associated BEB/BBB paracellular leak. Overall, this novel observation supports HSP90 inhibition mitigates KCl-induced BBB permeability and suggests the development of new therapeutic approaches targeting HSP90 in headache disorders.

No consensus criteria have been established regarding ideal candidates for indirect decompression with lateral lumbar interbody fusion (LLIF), and contributing factors of indirect decompression failure were rarely reported. We aim to investigate the success rate of indirect decompression by LLIF with proposed selection criteria and identify risk factors associated with indirect decompression failure, defined as persistent pain requiring revision with direct decompression.

Cholangiocarcinoma is a malignant neoplasm with a difficult diagnosis and unfavorable prognosis that can appear anywhere in the biliary tree. Anatomically, it can be classified as intra- or extrahepatic, the latter being the most common primary malignancy of the biliary tract. Although bone tissue is the third most common target for metastases in general, metastatic lesions from cholangiocarcinomas are uncommon in the head and neck.

The IL23/Th17 axis plays a strategic role in psoriasis (PSO). Guselkumab (GUS) is a selective inhibitor of the IL23p19 subunit. Its introduction has managed to increase the levels of efficacy, safety and survival in PSO. In real clinical practice, patients can loss effectiveness or suffered adverse events that forces a change in their treatments. There is scarce evidence of the effectiveness, safety, and survival of GUS in real clinical practice after anti-TNFα, anti-IL17, and/or anti-IL12/23. This is multicenter, observational and retrospective study of real clinical practice includes patients with moderate-to-severe plaque PSO in treatment with GUS. The objective of the study was to evaluate the effectiveness of GUS after anti-TNFα, anti-IL17, and anti-IL12/23. The study includes clinical information from February 2019 to February 2022. PASI, BSA, Pruritus, DLQI, survival, and safety were evaluated up to 76 weeks. Analyses were performed "as observed" using GraphPad Prism version 8.3.0 for Windows. A total of 103 patients were included in the analysis. At baseline there were significant differences between the anti-TNF, anti-IL17, and anti-IL12/23 groups for (1) dyslipidemia; (2) number of previous biological treatments and (3) PASI, BSA, VAS Pruritus, and DLQI scores. The effectiveness of GUS in terms of PASI, BSA, Pruritus, and DLQI was not impacted by previous biological alternatives. Treatment survival including discontinuations due to lack of effectiveness or safety reasons was 100%, 92.7%, and 92.1% for anti-TNFα, anti-IL17, and anti-IL12/23, respectively, at 130 weeks. No differences were found between groups. One adverse event was reported in the anti-LI12/23 group. The mid-term effectiveness, safety and survival of GUS if not impacted by previous biological therapy as anti-TNFα, anti-IL17, and/or anti-IL12/23. Our results indicate that GUS could be a switching strategy in patients who fail or present AE to other biological alternatives in moderate-to-severe PSO.
