Purpose: To evaluate peri-implant tissue health and bone resorption in patients with implant-supported fixed partial rehabilitations. In particular, possible correlations between plaque accumulation and bone loss, as well as other periimplant health parameters, were investigated. Materials and Methods: A total of 44 patients rehabilitated with fixed implant-supported partial rehabilitations were included. The following parameters were recorded: spontaneous bleeding (SB), suppuration, bleeding on probing (BOP), plaque index (PI), and probing depth (PD). Periapical radiographs were taken to measure crestal bone loss (BL). A nonparametric test (Spearman rank coefficient; rs) was used to identify possible correlations between the clinical parameters recorded. Results: A total of 121 implants were analyzed. Global PI and BOP were 49.58% and 20.25%, respectively. There were no cases of suppuration, and only 2 implants showed spontaneous bleeding. Mean BL was 1.53 mm (SD: 0.98). No implants showed peri-implantitis. There was a weak, statistically significant correlation between PI and BL (rs = 0.27, P [2-tailed] = .99) and between PI and the other peri-implant parameters (BOP: rs = 0.14, P = .14; PD: rs = 0.04, P = .65; SB: rs = --0.08, P = .34). A very weak correlation was also found between BL and BOP (rs = 0.1, P = .2) and between BL and PD (rs = 0.02, P = .7). Correlation was found between BL and age (rs = 0.13, P = .81) and between the other peri-implant parameters and age using dichotomization (> or < 65 years; PI: rs = --0.14, P = .11; PD: rs = --0.21, P = .01; BOP: rs = --0.21, P = .01; SB: rs = 0.05, P = .53). No statistically significant correlations were found between the clinical parameters evaluated and the sex or the dental arch treated (maxilla vs mandible). In contrast, the correlation between periodontal parameters and years elapsed since surgery (follow-up) was significant. Conclusions: The present research suggests that in implant-supported fixed partial rehabilitations, dental implants with greater plaque accumulation are more likely to present augmented probing depth, peri-implant inflammation, and bone loss, although the correlation is statistically very weak. Patient age and time of follow-up also significantly affected peri-implant health parameters. [ABSTRACT FROM AUTHOR]

Phraseological Units (PUs) in a language often include quotations and the so-called authorial "winged words" ("geflügelte Worte" in Gläser 1986), which have a single known author. These units, by gaining popularity among the members of a community of speakers, take on a life of their own as PUs. This study illustrates how these quotations acquire meanings and uses that do not match those of the original formulation they derive from, which, in turn, sheds light on how linguistic expressions at large reach conventionalization through language change. Bernard Shaw (1856–1950) ranks high among the authors who have contributed most to the English Phrasicon. This study investigates two case studies where quotations by Shaw have made their way into the English language as PUs. These quotations, however, are often used, as we shall see, in a way that differs from the sense they had in their original context. This study analyses how some novel PUs are coined and can help us map the processes of semantic adaptation these PUs undergo as they become conventional. It also provides insights into what constitutes a PU and how their defining characteristics apply in these cases. [ABSTRACT FROM AUTHOR]

The use of machine translation (MT) systems by undergraduate and postgraduate students has been analysed in different studies (Sycz-Opoń and Gałuskina 2017; Jia et al. 2019; Loock and Léchauguette 2021, to mention a few). An analysis of the German-into-Basque translation of multi-word expressions (Sanz-Villar 2024) observed that students' dependence on MT systems was very high; i.e., traces of the MT proposals were found in the outputs of translation trainees. To specifically analyse the impact of MT proposals on students' translations, two tasks were designed in 2021 in which nine students participated. Both tasks consisted of translating an excerpt of a children's literary text from German into Basque. The first translation task was done with the aid of MT tools and the second was a from-scratch translation where the use of MT systems was not allowed. The goal of the present study is to compare the results of both tasks, focusing on the translation of phraseological units (PUs) to observe the features of students' translations accomplished with and without the aid of MT tools. Since students used MT outputs during the first translation task, machine-translated texts are also compared to human-translated ones. The results show that the tendency to retain the phraseological character of the original text is stronger in professional translations than in machine-translated texts. In general, reliance on MT system outputs when translating PUs is quite strong among trainee translators. When comparing the results of the two tasks, it was observed that for some students, the number of techniques used to maintain the phraseological level of the original text increased in the translation done without MT. Interestingly, examples of creative translations were found in the translations done without the aid of MT tools. [ABSTRACT FROM AUTHOR]

Polyurethanes (PUs) synthesized with blends of polycarbonate and polyester polyols (CD+PEs) showed intrinsic self-healing at 20 °C. The decrease in the polycarbonate soft segments content increased the self-healing time and reduced the kinetics of self-healing of the PUs. The percentage of C-O species decreased and the ones of C-N and C=O species increased by increasing the polyester soft segments in the PUs, due to higher micro-phase separation. All PUs synthetized with CD+PE blends exhibited free carbonate species and interactions between the polycarbonate and polyester soft segments to a somewhat similar extent in all PUs. By increasing the polyester soft segments content, the storage moduli of the PUs decreased and the tan delta values increased, which resulted in favored polycarbonate soft segments interactions, and this was related to slower kinetics of self-healing at 20 °C. Although the PU made with a mixture of 20 wt.% CD and 80 wt.% PE showed cold crystallization and important crystallinity of the soft segments, as well as high storage moduli, the intercalation of a small amount of polycarbonate soft segments disturbed the interactions between the polyester soft segments, so it exhibited self-healing at 20 °C. The self-healing of the PUs was attributed to the physical interactions between polycarbonate soft segments themselves and with polyester soft segments, and, to a minor extent, to the mobility of the polymeric chains. Finally, the PUs made with 40 wt.% or more polyester polyol showed acceptable mechanical properties. [ABSTRACT FROM AUTHOR]

This study presents the exploration of sequence‐defined polyurethanes (PUs) as a new class of heteropolymers capable of precise conformational control. Utilizing molecular dynamics simulations, the folding behavior of polyurethane chains is investigated of varying lengths (11, 20, and 50 monomers) in both vacuum and aqueous environments. The simulations reveal that the heterogeneous chains systematically refold to approach the designed target structures better than non‐designed chains or chains with artificially disrupted hydrogen‐bond networks. The subsequent synthesis of an optimized 11‐mer sequence (P1) is achieved through solid‐phase chemistry, with thorough characterization via NMR, MS, and SEC confirming the accuracy of the predicted sequence and its controlled chain length. Solubility tests showed favorable results across multiple solvents, highlighting the versatility of the designed polymer. This research underscores the potential of sequence‐defined polyurethanes to emulate the structural and functional attributes of biological macromolecules, opening new pathways for their application in catalysis, drug delivery, and advanced material design. The findings illustrate a promising direction for the development of synthetic polymers with tailored properties, emphasizing the transformative impact of sequence control in polymer chemistry.

Different polyurethanes (PUs) were synthesized with polycarbonate polyols of molecular weights of 500, 1000, and 2000 Da. Their self-healing abilities at 20 °C were tested, and their structural, thermal, and mechanical properties were analyzed. The PUs made with polycarbonates of molecular weights 500 (YC500) and 1000 Da (YC1000) exhibited self-healing at 20 °C, and the self-healing time of YC1000 was the shortest. The absence of crystallinity and the low degree of micro-phase separation favored self-healing at 20 °C in YC500. However, the presence of tack and the existence of allophanate species and urethane–carbonate and urea–carbonate hydrogen bonds disfavored self-healing. Consequently, the self-healing time at 20 °C of YC500 was longer than expected. On the other hand, YC1000 exhibited an "equilibrium" between urethane-carbonate and urea–carbonate hydrogen bonds and carbonate–carbonate interactions among the soft segments, so a particular structural order was produced that was associated with its fastest self-healing at 20 °C. The PU made with the polycarbonate of molecular weight 2000 Da did not exhibit self-healing at 20 °C because of its significant micro-phase separation, the presence of semi-crystalline soft domains, and the lower density of hydrogen bonds.

Suppurative cervical lymphadenitis sometimes resolves with oral antibiotic treatment; however, many children are hospitalized for intravenous treatment due to lack of improvement. When there is no substantial improvement, the possibility of a liquefaction process is considered, and as a result, source control such as needle aspiration or open surgical drainage is recommended. We examined, among pediatric patients hospitalized with suppurative cervical lymphadenitis, clinical and laboratory predictors for invasive intervention that may lead to early imaging and intervention, hasten recovery, and shorten length of hospitalization. We compared laboratory and clinical characteristics of pediatric patients hospitalized with suppurative cervical lymphadenitis during 2010-2017, according to 3 treatments: needle aspiration (N = 54), open surgical drainage (N = 37), and conservative adequate antibiotic treatment only (N = 292). Physical indicators such as local erythema and fluctuation were found as predictors for invasive interventions in hospitalized pediatric patients diagnosed with suppurative cervical lymphadenitis. No significant associations were found between invasive interventions and laboratory parameters assessed in this study. Children who underwent interventions displayed a prolonged average length of hospitalization and received extended antibiotic treatment prior to hospital admission. In hospitalized pediatric patients diagnosed with suppurative cervical lymphadenitis, physical examination findings are the main predictive factors for invasive interventions. Consequently, when such straightforward clinical findings are observed in the context of insufficient improvement during antibiotic treatment, they should prompt consideration of invasive intervention.

To present long-term experience with buccal mucosa posterior urethroplasty (BMPU) for refractory posterior urethral stenosis (PUS) or vesicourethral anastomosis stenosis (VUAS) either by perineal approach (PA) or by endourethroplasty (EUP). A single-center retrospective study of 38 consecutive patients operated on between 1999 and 2022. BMPU consisted of the transfer of onlay or tubular buccal mucosa grafts into dilated and/or incised strictures through an open or endourological approach. If VUAS or PUS recurred with short stenosis within the first 12 months after surgery, it was transected by a cold-knife direct vision internal urethrotomy (DVIU), referred to as an "auxiliary" DVIU. The primary outcome was 3-year stricture recurrence-free survival (SRFS). BMPU by perineal approach and EUP were performed in 27 (71%) and 11 (29%) patients, respectively. The 3-year SRFS was 65% for the whole cohort, with rates of 63% for the perineal approach and 73% for endourological approach. With permitted auxiliary DVIU, 3-year SRFS for the whole cohort was 81%. De novo incontinence occurred in 2 out of 18 preoperatively continent patients. Limitations include the retrospective nature of the single-center study and a small, heterogenous cohort of patients. We present 2 techniques of substitution urethroplasty with BMG in the management of PUS and VUAS with a low rate of recurrence or de novo incontinence. A novel endourological approach (EUP) is a promising minimally invasive alternative to the perineal approach. [ABSTRACT FROM AUTHOR]

In a multihospital cohort study of 3392 patients, positive urinalysis parameters had poor positive predictive value for diagnosing urinary tract infection (UTI). Combined urinalysis parameters (pyuria or nitrite) performed better than pyuria alone for ruling out UTI. However, performance of all urinalysis parameters was poor in older women.

Background/Objectives: Untreated hepatic abscesses (HAs) have an 80% mortality rate and can be caused by bacteria and fungi. Previously managed with surgery, current treatments now utilize interventional radiology and antibiotics, reducing complications to 2.5%. This study evaluates contrast-enhanced ultrasound (CEUS) for better drainage placement and monitoring, overcoming conventional ultrasound's limitations in detecting the HA liquefied portion. Methods: We conducted a retrospective study of 50 patients with HAs confirmed via computed tomography (CT) scans. Inclusion criteria comprised specific clinical symptoms and laboratory parameters. Both B-mode and CEUS were utilized for initial and follow-up imaging. Results: In the CEUS studies, the mean size of HAs was 6.26 cm, with pus displaying significantly lower echogenicity compared to the HA pouch and liver parenchyma in all phases. Classification by size (>6 cm, <6 cm) and volume (>113 mL, <113 mL) revealed differences in the assessment of fluid volume between CEUS and B-mode. Conclusions: CEUS is valuable for diagnosing, performing therapeutic procedures, and monitoring HA. It provides precise real-time assessment of HA morphology, including dimensions and volume. If the liquefied volume of an HA exceeds 113 mL, it may qualify for drainage placement. CEUS can replace CT as an effective, less harmful, and cheaper method, eliminating the need for multiple radiological departments. While CEUS is a safer, cost-effective alternative to CT for HA evaluation and monitoring, comprehensive clinical evaluation remains essential. Therefore, CEUS should be part of a broader diagnostic and monitoring strategy, not a stand-alone solution. [ABSTRACT FROM AUTHOR]

Aiming at the problem of difficulty in allocating channels efficiently for secondary users (SU) in complex and variable cognitive radio systems, this paper proposed a high throughput channel allocation protocol, TKMA protocol. The protocol constructed an utility matrix of user and channel based on primary user (PU) activities, SU real-time service demands, and channel conditions, etc., allocated channels with the objective of maximizing the total utility value of the SU system under the premise of guaranteeing the communication quality of the PUs, and solved the problem by using the improved Kuhn-Munkras algorithm and polling scheduling. To evaluate the performance of the protocol, it established a universal multi-user multi-channel cognitive radio system model, described the packet transmission process using queuing theory, and derived the performance indicators of SU through Markov steady-state solution. The experimental results show that the use of TKMA protocol yields better results in terms of total SU system throughput, average delay, average queue length, rejection rate and other metrics compared with the previously proposed simplification algorithm and the traditional equitable random assignment protocol, which proves the effectiveness of the proposed protocol and system model.

Peritonsillar abscess (PTA) is a frequent pathology. Treatment consists in drainage of the collection, associated to probabilistic antibiotic therapy. The usefulness of cytobacteriological testing (CBT) of the drainage pus is controversial. A retrospective study of patients managed for PTA between 2013 and 2020 in our university hospital was performed. The main objective was to assess the usefulness of CBT in the management of PTA. The secondary objectives were to determine the bacteriological profile involved in the onset of PTA and to assess the rate of bacterial resistance to antibiotics prescribed on a probabilistic basis. The study included 207 patients: 70 outpatients (33%) and 137 inpatients (67%). Probabilistic antibiotic therapy was implemented in 100% of patients. CBT was performed systematically and was negative in 106 patients, revealing oropharyngeal flora in 40% of cases, polymicrobial flora in 50% and sterile samples in 10%. In the 101 patients with positive CBT, the bacteria isolated were penicillin-sensitive in 99%. All patients were successfully treated. In the light of the bacteriological results, no changes were made to the probabilistic antibiotic therapy introduced on admission. CBT on drainage pus had no impact on the management of PTA. CBT is therefore unnecessary in patients with no comorbidities and no signs of severity at admission. [ABSTRACT FROM AUTHOR]

Background: Childhood urinary tract infections (UTIs) are among the most prevalent diseases. In recent years, the overuse of common antibiotics has increased antibiotic resistance among urinary tract pathogens worldwide, with changes in the pattern of microbial resistance varying by geographical area and time. Objectives: This study aims to investigate the pattern of microbial resistance of UTI pathogens in pediatric patients. Methods: In this cross-sectional study, children aged < 13 years with UTI and positive urine cultures, who were admitted to Bahrami Hospital in Tehran, Iran, between 2015 and 2019, were evaluated. The pathogens' frequency, their antimicrobial resistance, and clinical and demographic information were extracted from the patients' files. Statistical relationships between clinical and demographic data and antibiotic resistance were analyzed using appropriate statistical tests. Results: The files of 202 patients were evaluated. The majority of patients were female (79.2%). UTI was more common among the 12 - 60 months age group (36.3%) in females and the 1 - 12 months age group (50%) in males. The most common UTI pathogen was Escherichia coli (85.1%). The lowest rates of microbial resistance were related to Meropenem (0% resistance), Gentamicin (9.2%), and Amikacin (10.8%). Conversely, the highest resistance rates were observed for Cotrimoxazole (74.6%), Ampicillin (74.5%), and Cephalothin (64.9%). Conclusions: UTI is more common in females aged 1 to 60 months. E. coli is the most common cause of UTI. Microbial resistance to antibiotics used for empirical treatment, such as ceftriaxone, is high and changes over time. It is recommended to use alternative antibiotics and avoid the inappropriate administration of antibiotics. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the efficacy of split-thickness labial eversion periosteoplasty (EPP) for soft tissue closure in horizontal ridge augmentation of posterior mandibular regions using a bone shell onlay grafting technique. Materials and Methods: Sixteen patients (12 female and 4 male; mean age: 46.2 ± 8.7 years) with 18 horizontal bone defects in posterior mandibular regions were included for lateral onlay bone grafting using the bone shell technique. After lateral bone augmentation, the EPP was used for soft tissue closure and was prospectively followed up for wound healing efficacy using a modified scoring index. The scoring index included dichotomous (yes: 0 / no: 1) evaluation of the following items: (1) bleeding on palpation or spontaneously, (2) tissue color difference, (3) presence of hematoma, (4) presence of granulation tissue, (5) incomplete incision margin closure, (6) dehiscence with visible augmentation material, (7) presence of exudation, and (8) presence of suppuration. In addition, a visual analog scale (VAS) was used to quantify and record the amount of pain and swelling (0 = no pain/swelling and 5 = severe pain/swelling); VAS scores of 0, 1, and 2 were rated as 1 in the dichotomous scoring index, and VAS scores of 3, 4, and 5 were rated as 0. A summarized wound healing score consisting of all 10 items was assessed at days 2, 7, and 14 and at months 1 and 4 postoperatively, including a comparison of the follow-up evaluations. Results: The summarized healing score increased significantly (P < .01) between day 2 (score: 6.6 ± 1.1) and day 7 (score: 8.9 ± 1.0) but showed little difference between day 14 (score: 9.6 ± 0.6) and the 1- and 4-month follow-ups (score: 10.0 ± 0). There was no wound dehiscence and no incomplete incision margin adaptation. For the individual parameters evaluated, bleeding on palpation, hematoma, and exudation were the most frequent side effects at day 2 at 50%, 100%, and 22.2%, respectively, and at day 7 at 16.7%, 55.6%, and 22.2%, respectively. The average pain score and the swelling/edema score were initially 4.0 ± 0 and 3.0 ± 0.77 on day 2, with a significant decrease (P < .001) by day 7 (pain: 2.0 ± 0; edema/swelling: 2.0 ± 0.59) and day 14 (pain: 1.0 ± 0.42; edema/swelling: 2.0 ± 0.79) and complete absence (score: 0) at months 1 and 4. Conclusions: Labial split-thickness EPP facilitates flap advancement and enables tight soft tissue coverage in large horizontal posterior mandibular bone augmentations as a result of offset double-layer wound closure. Although this procedure is shown to be surgically demanding, the postoperative complication rate may be reduced significantly. [ABSTRACT FROM AUTHOR]

Purpose: The management of pressure ulcers (PUs) poses challenges due to their chronic nature and the lack of established conservative treatment methods. In this clinical trial, our objective was to examine the validity and safety of using a light-emitting diode device contained four wavelengths in the treatment of grade 2 sacral PUs. Method: A total of 38 patients were randomly assigned to two groups: sham device (Sham) and experimental device (LED) group. The treatment sessions were conducted over a period of four weeks, with a frequency of three times per week. The study was conducted in a double-blinded manner. The study assessed the primary validity by measuring wound size and re-epithelialization after 0 and 4 weeks. Secondary evaluations included epidermal regeneration, collagen density, and immunological markers. Safety was evaluated by monitoring adverse reactions throughout the trial. Result: The presence of eschar was found to have a significant impact on wound healing. Sham consisted of 15 wounds without eschar, while LED had nine. After treatment in without eschar situation, the post-treatment size of wounds in Sham was 13.80 ± 20.29%, while it was 3.52 ± 6.68% in LED. However, there was no significant difference (p = 0.070). And analysis of epidermal thickness showed a significant increase in LED (495.62 ± 327.09 μm) compared to Sham (195.36 ± 263.04 μm) (p < 0.0001). Conclusion: While LED treatment had a potential for wound reduction in PUs without eschar, we could not uncover evidence to support the efficacy of LED treatment in grade 2 PUs.

Background: Laparoscopic appendicectomy is commonly performed in Australia for treatment of acute appendicitis. Intra-abdominal abscess (IAA) is a potential complication following appendicectomy for acute appendicitis. Risk factors for developing post-operative IAA remain controversial and poorly defined. Laparoscopic washout may be performed for patients who develop complication(s) including IAA. The aim of this study was to define risk factors for both the development of IAA and identify patients who may require laparoscopic washout following appendicectomy. Methods: Data were obtained from 423 patients who underwent laparoscopic appendicectomy over a five-year period (2012–2017). Clinical (fever, haemodynamics, examination findings), biochemical (white cell count, neutrophil count, C-reactive protein, bilirubin, albumin), radiological (CT free fluid), and operative factors (inflammation, suppuration, free-fluid, perforation, histopathology) collected in the pre-, peri-, and post-operative period(s) were analysed. Results: 23 (5.4%) patients developed post-operative IAA. Duration of intravenous antibiotics was significantly longer in patients who developed IAA and in those who required laparoscopic washout (p < 0.0001). C-reactive protein (CRP) on admission (p < 0.05) and appendiceal perforation (p = 0.0005) were significantly higher in patients who either developed IAA or needed laparoscopic washout. No clinical or radiological finding predicted either the development of IAA or need for laparoscopic washout. Conclusion: Elevated CRP on admission may predict the development of post-operative IAA formation or the need for laparoscopic washout post-appendicectomy. Prolonged post-operative antibiotic use appears independent of the development of IAA as well as the need for laparoscopic washout. These data highlight the need for clear guidelines on peri-operative antibiotic use following appendicectomy. [ABSTRACT FROM AUTHOR]

Background: It is unclear whether antibiotics impact delirium outcomes in older adults with pyuria or bacteriuria in the absence of systemic signs of infection or genitourinary symptoms. Methods: We registered our systematic review protocol with PROSPERO (CRD42023418091). We searched the Medline and Embase databases from inception until April 2023 for studies investigating the impact of antimicrobial treatment on the duration and severity of delirium in older adults (≥60 years) with pyuria (white blood cells detected on urinalysis or dipstick) or bacteriuria (bacteria growing on urine culture) and without systemic signs of infection (temperature > 37.9C [>100.2F] or 1.5C [2.4F] increase above baseline temperature, and/or hemodynamic instability) or genitourinary symptoms (acute dysuria or new/worsening urinary symptoms). Two reviewers independently screened search results, abstracted data, and appraised the risk of bias. Full‐text randomized controlled trials (RCTs) and observational study designs were included without restriction on study language, duration, or year of publication. Results: We screened 984 citations and included 4 studies comprising 652 older adults (mean age was 84.6 years and 63.5% were women). The four studies were published between 1996 and 2022, and included one RCT, two prospective observational cohort studies, and one retrospective chart review. None of the four studies demonstrated a significant effect of antibiotics on delirium outcomes, with two studies reported a worsening of outcomes among adults who received antibiotics. The three observational studies included had a moderate or serious overall risk of bias, while the one RCT had a high overall risk of bias. Conclusions: Our systematic review found no evidence that treatment with antibiotics is associated with improved delirium outcomes in older adults with pyuria or bacteriuria and without systemic signs of infection or genitourinary symptoms. Overall, the evidence was limited, largely observational, and had substantial risk of bias. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to evaluate the prevalence, incidence, and associated demographic factors of chronic suppurative otitis media (CSOM), utilizing a nationwide healthcare claims database. Methods: This retrospective study utilized outpatient administrative claims data from the IBM MarketScan Research Database from 2007 to 2021. The database (11 246 909 584 claims with 148 147 615 unique patients) includes health data from the private-sector, Medicare/Medicaid, managed care providers, and EMR providers. Included patients had a diagnosis of CSOM based on ICD-9-CM and ICD-10-CM codes. Prevalence and health utilization were estimated by age, gender, and geographic region. Results: In the United States, the estimated CSOM prevalence and incidence was 0.46% and 0.03%, respectively. Among CSOM patients (n = 679 906), mean age (SD) was 8.1 (15.4) years, and 52.8% were male. Most patients (81.1%) were aged 0 to 10 years. CSOM prevalence was lower in females (OR = 0.64, 95% CI 0.64-0.65, P <.001), less common in older age (OR = 0.94, 95% CI 0.94-0.94, P <.001), and highest in the South region (OR = 2.08, 95% CI 2.06-2.09, P <.001). Conclusion: Our results show CSOM prevalence (0.46%) is similar to other developed countries. CSOM prevalence was highest in those aged 0 to 10 years, in males and in the South region. Of note, prevalence and cost are likely significantly underestimated given limitations in accurate ICD-CM coding and the exclusion of uninsured patients. Further epidemiological studies are warranted to characterize the impact of CSOM on the US healthcare system. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effectiveness of topical application of basic fibroblast growth factor (bFGF) on pressure ulcers (PUs). Method: Relevant randomised controlled trials (RCTs) published from database creation to July 2018 were systematically searched. Pooled risk ratios (RR) with 95% confidence intervals (95% CI) were calculated to assess mean healing time in days as a measure of treatment efficacy. Standardised mean differences (SMD) with 95%CI were calculated to assess the proportion of complete healing. Funnel plots and Egger's regression tests were used to assess publication bias. Results: In total, 12 RCTs encompassing 664 PUs were included. The pooled effect size demonstrated a significant difference in complete healing proportions between the control groups and subjects treated with bFGF (RR=1.61 (1.40–1.85); p<0.001) and mean healing time (SMD=–1.97 (–2.54– –1.40); p<0.001). There was no indication of significant publication bias in the primary analysis. Sensitivity analysis demonstrated that the results of the meta−analysis were reliable. Conclusion: In this review, topical application of recombinant bFGF was found to be effective in the treatment of PUs. Given the limitations of the reports included, additional RCTs of higher power are warranted to confirm our findings. [ABSTRACT FROM AUTHOR]

Background: The facial nerve is considered a crucial structure and is vulnerable to injury during middle ear and mastoid surgery. The facial canal could be dehiscent in certain populations; therefore, identifying it and avoiding injury to the nerve is an important step during otological surgeries. In this study, we assessed the rate of facial canal dehiscence (FCD) among patients undergoing surgery due to the presence of chronic suppurative otitis media (CSOM). Methods: A cross-sectional study was performed between June 2019 and May 2023. We included 102 patients (aged 8–70 years), admitted for primary tympanomastoid exploration due to the presence of CSOM with and without cholesteatoma at Azadi Teaching Hospital in Duhok/Iraq. Cases with a history of trauma or craniofacial abnormalities were excluded from the study. Also, none of the selected patients complained of facial nerve disorders. Results: Among the 102 patients who were admitted, 11.76% (n = 12) had FCD; they were between the ages of 11 and 58 (average: 30.9) years (18.8% ≤ 18 years vs. 10.5% > 18 years, p = 0.396). The dehiscence was more common in males than females (14.3% vs. 10.0%, p = 0.545) and was also more common on the left side than the right side (13.8% vs. 9.1%, p = 0.547). Of those with the dehiscent facial nerve, 83% (n = 10) had the dehiscence on the tympanic segment. The dehiscence was statistically more common in patients with cholesteatoma than those without (25.9% vs. 6.7%, p = 0.014). Conclusion: Dehiscence in the facial nerve can be encountered in patients with CSOM, particularly those with cholesteatoma. In such patients, the dehiscence is most commonly found on the tympanic segment of the facial nerve, so care should be taken during surgery for such cases to avoid injury of the nerve.

Background Materials and Methods Results Conclusions The present systematic review evaluated clinical and radiographic features and treatment outcomes of peri‐implantitis‐induced medication‐related osteonecrosis of the jaws (Pi‐MRONJ).Literature search was performed in PubMed/MEDLINE, Cochrane CENTRAL, Web of Science, and Scopus databases. Studies reporting Pi‐MRONJ were included. No time restrictions were applied.In total, 571 articles were retrieved, and 24 articles were included in the final review. Study population consisted of 111 patients (70% pharmacologically treated for osteoporosis and 30% for oncologic disease). Pi‐MRONJ was characterized by pain, bone exposure and suppuration, and involved a single implant in 55 cases, two implants in 37 cases, three implants in 10 cases, and more than four implants in nine cases. Most of the lesions were assigned Stage II and III. MRONJ developed on average 46.5 ± 33.2 months following implant placement. Sixty‐one lesions were surgically treated with implant removal and debridement of the surrounding necrotic bone. Complete wound healing was observed in 85% of cases.The presence of dental implants in patients treated with antiresorptive drugs should be considered as a potential risk factor for MRONJ onset. In cases of periimplantitis with delayed wound healing following nonsurgical therapy, the clinician should rule out the presence of Pi‐MRONJ. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Urinary tract infections (UTIs) are common, but overdiagnosed, in children with spina bifida. We sought to evaluate the diagnostic test characteristics of urinalysis (UA) findings for symptomatic UTI in children with spina bifida. METHODS: Retrospective cross-sectional study using data from 2 centers from January 1, 2016, to December 31, 2021. Children with myelomeningocele aged <19 years who had paired UA (and microscopy, when available) and urine culture were included. The primary outcome was symptomatic UTI. We used generalized estimating equations to control for multiple encounters per child and calculated area under the receiver operating characteristics curve, sensitivity, and specificity for positive nitrites, pyuria ($10 white blood cells/high-powered field), and leukocyte esterase (more than trace) for a symptomatic UTI. RESULTS: We included 974 encounters from 319 unique children, of which 120 (12.3%) met our criteria for UTI. Pyuria had the highest sensitivity while nitrites were the most specific. Comparatively, nitrites were the least sensitive and pyuria was the least specific. When the cohort was limited to children with symptoms of a UTI, pyuria remained the most sensitive parameter, whereas nitrites remained the least sensitive. Nitrites continued to be the most specific, whereas pyuria was the least specific. Among all encounters, the overall area under the receiver operating characteristics curve for all components of the UA was lower in children who use clean intermittent catheterizations compared with all others. CONCLUSIONS: Individual UA findings have moderate sensitivity (leukocyte esterase or pyuria) or specificity (nitrites) but overall poor diagnostic accuracy for symptomatic UTIs in children with spina bifida.

Background and Aim: Periodontal surgeries complications and related factors are one of the most important things that surgeons in each clinic should be aware of to prevent them. Therefore, the aim of this study was to determine and compare the frequency, severity and trend of complications after periodontal flap surgeries with and without ostectomy and related factors in the periodontics department of Tehran University of Medical Sciences. Materials and Methods: patients in the periodontics department of Tehran University of Medical Sciences, who underwent periodontal flap surgery or gingivectomy, were included in this prospective study. The pain, swelling, and bruising levels were asked on the same day, one and three days later. At the follow-up session on the seventh day, the pain, swelling and bruising levels were asked again, the tenderness and swelling levels were recorded by the surgeon, and flap dehiscence and pus presence were assessed. The difference between the complications’ levels on different days and also the difference in their trends between different surgeries was measured by GEE test, alongside testing the association of background and surgery characteristics with the complications’ levels by MannWhitney and correlation tests. Results: The pain and swelling means on days 0 and 1 respectively were significantly higher than other days. The trend of means for complications were not different between the two groups of flap surgery with and without ostectomy. Tenderness, swelling, flap dehiscence and pus were present in 31%, 31%, 1% and 0% of patients after one week, respectively. Conclusion: Complications after periodontal flap surgeries were uncommon, except for mild pain and swelling. [ABSTRACT FROM AUTHOR]

A new uranyl silicate Cs4[(UO2)5(SiO3OH)2O2F4] (1), was obtained via a hydrothermal route. The new compound is monoclinic, P21/n, a = 8.3870(2), b = 13.4612(2), c = 10.9503(2) Å, β = 91.223(2)°, V = 1236.00(4) Å3; the structure has been solved and refined down to R1 = 0.022. Therein, the phosphouranylite units (PUs) associate into a new type of uranyl-silicate layers, [(UO2)5(SiO3OH)2O2F4]4−, which interleave with the Cs+ cations. Topological analysis of PU based structures indicates that these layers in 1 provide a unique example of complexes constructed only via association of the PU and not involving other building units.

Summary: Three populations of Pauronemoides siddiqii n. gen., n. sp. were recovered from three different locations in northwestern and northern Iran from bark and soil samples. The new genus was described and illustrated based upon morphological and molecular characteristics. Pauronemoides n. gen. belongs to the family Paurodontidae and is characterised by the medium-sized body, asymmetrical knobs in stylet base, stem-like extension into intestine, post-vulval uterine sac (PUS) absent or rudimentary, different tail tip shape between sexes, and bursa enveloping tail or reaching to the tail end. The type species, Pauronemoides siddiqii n. gen., n. sp., is mainly characterised by 752-1281 μ m body length in females and 660-1085 μ m in males, six equally-sized lips, stylet 9-11 μ m long with asymmetrical knobs, six incisures in lateral fields forming five bands, three of which (two outers and one central) are wider, and variably lengthened stem-like extension projecting into the intestine. Vulva situated posteriorly (V = 87.7-91.7%), PUS absent. Conical tail with widely rounded end, having a small mucron at tip in females, males with conical tail ending to a narrower tip and bursa enveloping tail completely. The type species of the new genus was compared with all known species of the genera Prothallonema , Paurodontus , Paurodontoides and Paurodontella. Pauronemoides siddiqii n. gen., n. sp. resembles Prothallonema macrocellum and P. mucronatum by having the bulb extension penetrating into the intestine, dimorphism in tail shape of both sexes and bursa enveloping tail, and Paurodontella iranica by tail shape dimorphism between sexes and bursa ending near tail tip. Therefore, the above-mentioned species are transferred to the new genus as Pauronemoides macrocellus n. gen., n. comb. (= Prothallonema macrocellum), P. mucronatus n. gen., n. comb. (= Prothallonema mucronatum) and P. iranicus n. gen., n. comb. (= Paurodontella iranica). In addition to morphological comparisons, molecular phylogenetic analyses were performed using two sequences of small subunit (SSU), and three partial sequences of D2-D3 expansion segments of the large subunit (LSU) rDNA, and the resulting topologies were discussed.

Purpose: To identify associations with unplanned repeat irrigation and debridement (I&D) after arthrotomy for native septic arthritis. Methods: A retrospective review identified patients with native septic arthritis treated with open arthrotomies. The primary outcome was unplanned repeat I&D within 90 days. Associations evaluated for included comorbidities, ability to bear weight, fever, immunosuppressed status, purulence, C-reactive protein, erythrocyte sedimentation rate, white blood cell count (synovial fluid and serum levels), and synovial fluid polymorphonuclear cell percentage (PMN%). Results: There were 59 arthrotomies in 53 patients involving the knee (n = 32), shoulder (n = 10), elbow (n = 8), ankle (n = 6), and hip (n = 3). The median patient age was 52, and a 71.2% were male. An unplanned repeat I&D was required in 40.7% (n = 24). The median time to the second I&D was 4 days (interquartile range 3 to 9). On univariate analysis, unplanned repeat I&Ds were associated with fever (p = 0.03), purulence (p = 0.01), bacteria growth on cultures (p = 0.02), and the use of deep drains (p = 0.05). On multivariate analysis, the only variables that remained associated with unplanned repeat I&Ds were fever (odds ratio (OR) 5.5, 95% confidence interval (CI) 1.3, 23.6, p = 0.02) and purulence (OR 5.3, CI 1.1, 24.4, p = 0.03). Conclusions: An unplanned repeat I&D was required in 40.7% of patients and was associated with fever and purulence. These findings highlight the difficulty of controlling these infections and support the need for future research into better methods of management. Level of evidence: Diagnostic, Level III.

Background: Retronychia is characterized by proximal ingrowing of the nail plate into the proximal nail fold. It is always associated with the presence of two or more overlapping nail plates under the proximal nail fold, clinical signs of chronic proximal paronychia refractory to antimicrobial treatment, and a yellowish nail that does not grow. It mainly affects young female adults, with less than 30 pediatric cases described in the literature so far. Methods: Retrospective and observational study of patients between 0 and 18 years with a clinical and/or ultrasound diagnosis of retronychia attending a pediatric dermatology service between December 2020 and January 2022. Results: We identified 9 patients with retronychia, 7 girls and 2 boys. In all cases, the hallux nails were affected with 5 unilateral and 4 bilateral cases. On physical examination we observed the following signs: thickened and opaque nail plate (one patient), yellowish nail plate (7 patients), double nail plate (6 patients), and erythema with edema, pain, and suppuration of the proximal nail fold (7 patients). Ultrasound was performed in 7 patients and specific findings of retronychia were found in 5 of them. All patients received topical treatment and were referred for the appropriate surgical treatment. To date, only one patient underwent nail avulsion, which was followed by complete recovery. Conclusions: Retronychia is underdiagnosed, particularly in the pediatric population. We present a series of 9 cases of retronychia in children, with clinical and ultrasonographic findings consistent with those of adults. We emphasize the importance of recognizing this entity, which will allow early and adequate treatment. [ABSTRACT FROM AUTHOR]

Aim: To evaluate long‐term outcomes and prognostic factors of non‐reconstructive surgical treatment of peri‐implantitis. Materials and Methods: One hundred forty‐nine patients (267 implants) were surgically treated for peri‐implantitis and followed for an average of 7.0 (SD: 3.6) years. The primary outcome was implant loss. Additional bone loss and surgical retreatment were secondary outcomes. Patient/implant characteristics, as well as clinical and radiographic parameters collected prior to initial surgery, were evaluated as potential predictors of implant loss. Flexible parametric survival models using restricted cubic spline functions were used; 5‐ and 10‐year predicted rates of implant loss were calculated according to different scenarios. Results: Fifty‐three implants (19.9%) in 35 patients (23.5%) were lost during the observation period. Implant loss occurred after a mean period of 4.4 (SD: 3.0) years and was predicted by implant surface characteristics (modified surface; HR 4.5), implant length (HR 0.8 by mm), suppuration at baseline (HR 2.7) and disease severity (baseline bone loss: HR 1.2 by mm). Estimates of 5‐ and 10‐year implant loss ranged from 1% (best prognostic scenario; initial bone loss <40% of implant length, turned implant surface and absence of suppuration on probing (SoP)) to 63% (worst prognostic scenario; initial bone loss ≥60% of implant length, modified implant surface and SoP) and from 3% to 89%, respectively. Surgical retreatment was performed at 65 implants (24.3%) in 36 patients (24.2%) after a mean time period of 4.5 (3.1) years. In all, 59.5% of implants showed additional bone loss, were surgically retreated or lost. Conclusions: Recurrence of disease is common following surgical treatment of peri‐implantitis. The strongest predictor for implant loss was implant surface characteristics. Implant length as well as suppuration and disease severity at baseline were also relevant factors.

Background: Hand infections are a common reason for presenting to hospital and can be associated with significant morbidity and prolonged antibiotic use. Factors recognized to influence patient outcomes include resistant organisms and delayed presentation. Surgeons working around Australia may assume that hand infections and appropriate treatment algorithms will be similar between sites. This is the first study to examine differences between hand infections presenting in Darwin (with its tropical climate) vs. those in a more temperate city (Adelaide). Methods: This is a two‐site retrospective study, where diagnostic discharge codes were used to identify cases for a 12‐month period and patient age, sex and rurality, duration of hospital stay, microbiology results and subsequent trips to theatre were reviewed. Results: Despite significant differences in rurality between FMC and RDH patients, there was no significant difference in length of hospital stay, duration of intravenous antibiotics or return trips to theatre across the two sites. RDH reported a 25% rate of MRSA, compared to 18% at FMC, as well as a statistically significant increase in uncommon microbes, with 30% compared to 12% of patients growing microbes that may not be covered by antibiotics routinely administered in metropolitan areas. A limitation of this study was that compliance with antibiotics and hospital stay were not accounted for. Conclusion: It is often our training years that determine our norms of everyday practice, but fewer Australian surgical training posts are located in tropical centres. The results of this study highlight the importance of not assuming that the spectrum of organisms causing hand infections are the same as that in the surgeons' state of origin.

Necrotizing fasciitis (NF) is a fatal disease with a high mortality rate that can be easily misdiagnosed. The aim of this study was to improve the diagnostic rate of NF and overall survival. We conducted a single-center, retrospective, noncontrolled study involving 36 patients who were admitted to our department between December 2017 and October 2019, and summarized the diagnostic key points and timing of surgical treatment. All patients were diagnosed at our department and underwent multiple courses of treatment. The records included information regarding underlying diseases, bacterial culture results, laboratory risk indicator for necrotizing fasciitis (LRINEC) score, number of procedures, and type of antibiotics. All 36 cases of NF were cured and showed good patient condition on follow-up; the mean number of surgeries was three, and the mean duration of hospitalization was 37 days (range, 21-83 days). The LRINEC scores of 16 patients were ≥8 points. Seventeen patients with underlying diabetic disease had higher inflammatory index scores than those without diabetes. The LRINEC scores of patients with (n = 17) and without (n = 19) DM were 7.40 ± 2.99 and 3.80 ± 2.39, respectively (P <.01). Cases of NF that were treated with early incision and surgical abscess drainage required fewer surgeries and a shorter length of hospitalization. Thus, surgeons should be more aware of NF and aim to make an early and accurate diagnosis using various approaches. Complete surgical debridement plays an essential role in NF treatment, and diabetes mellitus is a significant adverse factor that exacerbates the severity of NF. Negative-pressure techniques are useful in cases involving nonanaerobic infections and cause minimal complications. [ABSTRACT FROM AUTHOR]

2-Bromopropionyl bromide esterified cellulose nanofibrils (Br-CNFs) facilely synthesized from one-pot esterification of cellulose and in situ ultrasonication exhibited excellent N,N-dimethylformamide (DMF) dispersibility and reactivity to partially replace either chain extender or soft segment diol in the stoichiometrically optimized syntheses of polyurethanes (PUs). PUs polymerized with Br-CNF to replace either 11 mol% 1,4-butadiol chain extender OHs or 1.8 mol% polytetramethylene ether glycol OHs, i.e., 1.5 or 0.3 wt% Br-CNF in PUs, exhibited an over 3 times increased modulus, nearly 4 times higher strength, and a 50% increase in strain. In either role, the experimental modulus exceeding those predicted by the Halpin-Tsai model gave evidence of the stoichiometrically optimized covalent bonding with Br-CNF, while the improved strain was attributed to increased hydrogen-bonding interactions between Br-CNF and the soft segment. These new Br-CNFs not only offer novel synthetic strategies to incorporate nanocelluloses in polyurethanes but also maximize their reinforcing effects via their versatile polyol reactant and cross-linking roles, demonstrating promising applications in the synthesis of other polymers.

The article discusses research which determined the rate of antibiotic treatment of children with urinary tract infection without pyuria whose bag urine cultures (UCx) were mislabeled as catheterized or clean catch. The study describes the demographic characteristics of children with positive UCx. It compared the treatment rate of patients with correct documentation of bag UCx in follow-up treatment decisions and determined the frequency with which urine specimens were mislabeled.

Background: Goblet cell adenocarcinoma is an extremely rare tumor in which the same cells exhibit both mucinous and neuroendocrine differentiation. It is considered more aggressive compared to conventional carcinoids and more likely to cause metastasis. Case presentation: We report a case of goblet cell adenocarcinoma with peritoneal metastases. A 62-year-old man underwent appendectomy for acute appendicitis. Intraoperatively, inflammatory white pus and a small amount of dirty ascites were observed in the lower abdomen with severely inflamed appendix. Histopathological examination of the specimen collected during appendectomy revealed goblet cell adenocarcinoma with a positive surgical margin. One month later, additional ileal resection was planned. Laparoscopic examination revealed disseminated nodules throughout the abdominal cavity. Therefore, the patient underwent resection of the peritoneal nodules. The peritoneal specimens confirmed the histopathological findings. Thus we diagnosed the patient with peritoneal dissemination of appendiceal goblet cell adenocarcinoma. Conclusions: In cases wherein white pus is observed during surgery for acute appendicitis, considering the possibility of dissemination, collecting samples for histopathological examination, and initiating early treatment are crucial.

Objectives To determine the effect of antimalarial agents (AMA) and different doses and pharmaceutical forms of belimumab on preventing renal flares in patients with SLE treated for extra-renal disease. Methods We pooled data from the BLISS-52, BLISS-76, BLISS-SC and BLISS-Northeast Asia trials of belimumab (n  = 3225), that included patients with active SLE yet no severe ongoing nephritis. Participants were allocated to receive intravenous belimumab 1 mg/kg, intravenous belimumab 10 mg/kg, subcutaneous belimumab 200 mg, or placebo in addition to standard therapy. We estimated hazards of renal flare development throughout the study follow-up (52–76 weeks) using Cox regression analysis. Results In total, 192 patients developed a renal flare after a median of 197 days. Compared with placebo, the risk of renal flares was lower among patients receiving intravenous belimumab 10 mg/kg (HR: 0.62; 95% CI: 0.41, 0.92; P  = 0.018) and intravenous belimumab 1 mg/kg (HR: 0.42; 95% CI: 0.22, 0.79; P  = 0.007), while no significant association was found for subcutaneous belimumab 200 mg. AMA use yielded a lower hazard of renal flares (HR: 0.66; 95% CI: 0.55, 0.78; P  < 0.001). The protection conferred was enhanced when belimumab and AMA were co-administered; the lowest flare rate was observed for the combination intravenous belimumab 1 mg/kg and AMA (18.5 cases per 1000 person-years). Conclusions The protection conferred from belimumab against renal flare development in patients treated for extra-renal SLE appears enhanced when belimumab was administered along with AMA. The prominent effect of low-dose belimumab warrants investigation of the efficacy of intermediate belimumab doses.

Brain abscess is a serious clinical condition caused by a localized collection of pus within the brain tissue. This typically occurs as a result of an infection that originates from a nearby area, such as an ear, sinus, or dental infection, or an infection in the bloodstream. Streptococcus and Staphylococcus species are the most common organisms implicated in brain abscesses. Apart from aerobic growth, cases of mixed infections of both aerobic and anaerobic organisms are also commonly reported in the literature. Herein we report a 23-year-old immunocompetent female with chronic otitis media who presented with cerebellar abscess where the aerobic growth was sterile and anaerobic culture revealed pure growth of dual anaerobes viz... Peptostreptococcus and Bacteroides thetaiotaomicron. This case highlights the importance of prompt diagnosis and management of polymicrobial anaerobic infection in cases of brain abscess.

Urinary tract infections (UTIs) are a significant public health problem. Every year the situation becomes more complicated due to the high rate of recurrence and the growth of resistance among the population. Research results show that about 150 million people suffer from bacterial infections of the urinary tract every year, and about 6 million visits to the doctor about UTIs are registered in the US every year, of which more than 2 million are related to cystitis. In Ukraine, UTIs rank first among all urological diseases, more than 170,000 cystitis patients are registered annually for the first time. 20% of girls till 20 years old have at least one episode of acute cystitis, and 25–40% of women experience a recurrent episode within a year after an episode of acute cystitis. Treatment of cystitis depends on the influence of many factors, which include: age, gender, state of the immune system, recurrences, urological pathologies, severity of the disease and the risk of developing multiple drug resistance. For the prevention of the antibiotic resistance development, it is recommended to use combined herbal preparations for long-term prevention of episodes of recurrent cystitis. The objective: to evaluate the effectiveness of the use of the proposed herbal preparation in the complex treatment and prevention of recurrence in patients with acute uncomplicated cystitis and the chronometry of the onset of action of the drug in monotherapy. Materials and methods. The study was included the patients with acute uncomplicated cystitis. The main group involved 40 persons who were prescribed antibacterial therapy in the form of a single use of fosfomycin trometamol 3 g per os or sulfamethoxazole/trimethoprim 400 mg/80 mg 2 tablets twice a day for 5 days in combination with a herbal preparation (a combination of medicinal plant components of centaury herb, lovage root and rosemary leaves) 1 tablet 3 times a day for 3 months. Patients of the comparison group (40 subjects) received only antibacterial therapy. Treatment effectiveness and side effects were evaluated 10 days after its initiation. Determination of the presence and frequency of recurrence of the disease was carried out 3 and 6 months after its onset. At the second stage of the study, the effectiveness of the use of the herbal preparation was evaluated as a prevention of recurrence of cystitis and relief of its first signs. At the appearance of the first signs of recurrence of the disease within 6 months after the end of the primary course, patients of both groups were recommended to immediately start using the herbal preparation, 1 tablet three times a day. To determine the speed of the onset of the pharmaceutical action of the drug, each patient was asked to fill out a questionnaire regarding the chronometry of the reduction or disappearance of symptoms. Results. After completion of treatment, a positive effect was observed in 38 (95.0%) patients of the main group and 37 (92.5%) of the comparison group, leukocyturia stopped in 39 (97.5%) and 38 (95.0%) patients, respectively, dysuria – in 37 (92.5%) and 38 (95.0%), respectively. The effect of the proposed herbal preparation was maximally manifested in reducing the rate of recurrence of cystitis, which has important clinical significance. It is quite clear that for the occurrence of a sporadic episode of acute cystitis, timely and effective antibiotic therapy is selfsufficient and accordingly hides the effect of phytotherapy. Use of the proposed herbal preparation for 3 months provides long-term rehabilitation of the lower urinary tract due to the aquaretic and antimicrobial effect of the herbal preparation and prevents the recurrence of the disease. Conclusions. The use of the proposed herbal preparation as part of combined therapy in patients with acute uncomplicated cystitis demonstrated its effectiveness in 95.0% of patients. The appointment of the proposed drug of plant origin prevents the occurrence of recurrence in 97.5% of patients, which allows us to recommend it for use in order to prevent relapses of the disease. The use of the proposed preparation of herbal origin helps to reduce the feeling of incomplete emptying of the bladder, starting from 62.9±17.0 min and the disappearance of pollakiuria – by 179.7±23.0 min, which allows to make quick assess of phytotherapy effectiveness and, if necessary to strengthen it in time.

Background: Nosocomial infections caused by Serratia marcescens mostly occurred in pediatrics and it was very rarely reported after adult surgery. Here, an intracranial abscess caused by Serratia marcescens was reported. Case summary: We report a rare case of a postoperative intracranial abscess caused by Serratia marcescens in a 63-year-old male patient with a left parietal mass. The patient underwent resection of the mass on June 1, 2022, and the postoperative pathology revealed an angiomatous meningioma, WHO I. He then experienced recurrent worsening of right limb movements, and repeated cranial CT scans showed oozing blood and obvious low-density shadows around the operation area. Delayed wound healing was considered. Subsequently, a large amount of pus was extracted from the wound. The etiological test showed that Serratia marcescens infection occurred before the removal of the artificial titanium mesh. Antibiotics were initiated based on the results of drug susceptibility tests. At present, the patient is recovering well and is still closely monitored during follow-up. Conclusion: It is rare for Serratia marcescens to cause brain abscesses without any obvious signs of infection. This report provided in detail our experience of a warning postoperative asymptomatic brain abscess caused by an uncommon pathogen. [ABSTRACT FROM AUTHOR]

The study introduces OnomOs, a new corpus of Czech texts with annotation of proper names. The corpus was compiled by onomasticians from the Department of Czech Language, Faculty of Arts, University of Ostrava, and made available by the Institute of the Czech National Corpus, Faculty of Arts, Charles University in Prague. The paper briefly discusses the content and structure of the cor- pus, the selection of texts for inclusion, and the onomastic-geographical classification of the iden- tified names. The text consists chiefly of three preparatory analyses, which focus on the most fre- quent surnames, collocations found in Western and Eastern countries in the pre-1989 period, and the declension patterns of three types of onyms. In the summary, further possibilities of onomastic corpus research are presented. [ABSTRACT FROM AUTHOR]

Osteolytic lesions refer to the destruction of any part of bone due to a disease process (pertaining to dissolution of bone, especially loss of calcium). Osteomyelitis is the inflammation of the bone caused by an infecting organism. Although bone is normally resilient to bacterial colonization, events such as trauma, surgery, infections, the presence of foreign bodies, and anemia may disrupt bony integrity and lead to the onset of bone infections. Sometimes, osteomyelitis causes no signs and symptoms or the signs and symptoms are hard to distinguish from other problems. This may be true for children, older adults, and people whose immune systems are compromised. Here, we report a case of chronic intermedullary inflammation of bone in a child. [ABSTRACT FROM AUTHOR]
