Severe cholecystitis during the COVID-19 pandemic : Influence of the COVID-19 pandemic on the frequency of surgery and outcome for elective and emergency cholecystectomy: a monocentric retrospective cohort analysis

With the outbreak of the COVID-19 pandemic medical care focused on management of the infectious event. Elective interventions were cancelled and the general advice was to stay at home. How this impacted urgent and elective cholecystectomies is the subject of this work. Urgent and elective cholecystectomy patients during the first year of the pandemic were compared with those of the previous year. The primary endpoint was the frequency of surgery. Furthermore, the American Society of Anesthesiologists (ASA) score, symptom duration until presentation as well as until surgery, preoperative inflammatory parameters, imaging, positive Murphy's sign, type and duration of surgery, intraoperative drain placement, intraoperative and histological severity, need for and duration of postoperative antibiotic therapy, intensive care stay, length of stay and occurrence of postoperative complications were recorded. During the pandemic patients were sicker (ASA2.13 vs. 2.31; p = 0.039), the operating time was prolonged (64.4 min vs. 74.9 min; p = 0.001) and patients were more likely to have concomitant peritonitis (15.4% vs. 29.1%: p = 0.007). Furthermore, there was atrend in the presence of leukocytosis, apositive Murphy's sign, intraoperative drain placement, intraoperative severity of inflammation, duration of postoperative antibiotic therapy and complication rate. During the COVID-19 pandemic cholecystitis presented with more pronounced inflammation, the surgical conditions were more difficult and postoperative recovery was prolonged.

Surgical management of headache and facial pain/pressure in chronic rhinosinusitis: A systematic review and meta-analysis.

Headache and facial pain are common symptoms of chronic rhinosinusitis (CRS). However, given the numerous etiologies that can cause these symptoms, the impact of sinus surgery is not well characterized. A systematic review was performed by searching the literature from inception through June 6, 2023. English-language articles reporting outcomes for facial pain/pressure or headache following endoscopic sinus surgery were selected for inclusion. Meta-analyses were performed using random and fixed effect models on continuous measures (mean), mean difference (Δ), and proportions (%). A total of 26 articles reporting on 2839 patients were selected for inclusion. The mean patient age was 44.0±3.9 (range 16.0-84.0), with an average symptom duration of 5.3±2.8 years. Among these patients, 56.5% (95% confidence interval [CI]: 52.3-60.6) were male and 77.0% (95% CI: 56.6-92.3) had nasal polyposis (NP). Patients with and without NP reported substantial reductions in both 22-item sino-nasal outcome test facial pain/pressure (with NP: -1.4 [95% CI: -1.6 to -1.2; relative reduction 59.1%]; without NP: -1.5 [95% CI: -1.9 to -1.1; relative reduction 60.9%]) and visual analogue scale (VAS) headache (with NP: -2.5 [95% CI: -2.8 to -2.1; relative reduction 67.2%]; without NP: -2.8 [95% CI: -4.7 to -1.0; relative reduction 42.7%]). Symptom reductions were greater in the without NP versus with NP group; VAS facial pain/pressure: Δ0.4 (95% CI: 0.2-0.6; p=0.0006) and VAS headache: Δ0.4 (95% CI: 0.1-0.7; p=0.02). Our findings suggest that CRS patients, regardless of polyp status, benefit from significant reductions in facial pain/pressure and headache following surgical therapy.

Squamous cell carcinoma of the nail in patients with Fitzpatrick phototypes IV-VI: a systematic review.

Squamous cell carcinoma of the nail unit (nSCC) is a rare malignant tumor of the hand and nail. Although skin cancer rarely affects individuals with phototypes IV-VI, its occurrence in these groups is often associated with greater morbidity and mortality. This study aims to characterize the clinical symptoms, presentations, and treatments of nSCC in patients with darker skin types. A systematic review of PubMed and Embase was performedin May 2023 for all peer-reviewed, English-language nSCC studies involving individuals with Fitzpatrick types IV-VI. Most tumors were located on the fingernails (84%), with the right third finger being the most frequently affected (31%). The nail bed (67%) exhibited a higher prevalence than the lateral/proximal nail folds (33%). The duration of symptoms before diagnosis ranged from 1 month to 7 years. nSCC was most commonly treated with Mohs surgery (38%), followed by amputation (35%). Our study was limited to case reports because of a lack of large nSCC studies that provide information on race or images of each patient. These tumors are generally slow-growing yet often misdiagnosed, leading to delays in presentation and diagnosis. Increased awareness about nSCC in phototype IV-VI individuals will reduce misdiagnoses, unnecessary treatment, and recurrences.

Management and Outcomes of Facial Nerve Hemangiomas: A Systematic Review of the Literature

Abstract Objectives To conduct a systematic review of facial nerve hemangiomas (FNH), focusing on patient characteristics, management options, and treatment outcomes. Design A systematic review was performed following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, utilizing PubMed, EMBASE, Scopus, and Cochrane databases from inception to December 31, 2022. Setting Literature sourced from various databases providing information on FNH cases. Participants A total of 176 patients with FNH were included in the study, identified from 40 articles meeting inclusion criteria. Main Outcome Measures Patient demographics, lesion characteristics, preoperative symptoms, surgical approaches, and postoperative outcomes, including House-Brackmann (HB) grades. Results Among the 1,682 initially identified articles, 40 were included in the final review. From these, a total of 176 patients (mean age = 42.7 ± 12.8, 51.1% male) were included for analysis. Bivariate analysis showed that patients with longer preoperative symptom duration and facial nerve sacrifice had significantly greater postoperative HB Grades (p < 0.001). Additionally, a strong positive correlation was observed between pre- and postoperative HB Grades (Spearman's rho = 0.649). Multivariable linear regression analysis showed that both facial nerve sacrifice (β = 0.86, 95% confidence interval [CI]: 0.38–1.34; p < 0.001) and greater preoperative HB Grades (β = 0.36, 95% CI: 0.20–0.53; p < 0.001) were associated with significantly greater postoperative HB Grades, but preoperative symptom duration did not persist as a significant predictor of postoperative HB Grades. Conclusions FNHs are rare lesions of the skull base affecting the temporal bone. Our findings highlight the role of preoperative facial nerve function and intraoperative preservation of the facial nerve in predicting postoperative outcomes. Timely resection of lesions that prioritizes facial nerve preservation is critical to achieving optimal patient outcomes.

Outcomes of the Transungual Approach in 56 Consecutive Digital Subungual Glomus Tumours.

Background: Glomus tumour is a painful small tumour of the glomus body commonly located under the nail bed. The aim of this study is to evaluate the correlation of clinical diagnosis with MRI findings, determine the prevalence of the tumour at different subungual locations and determine the differences in outcomes (if any) between a longitudinal and a transverse nail bed incision for excision of the tumour. Methods: This retrospective study of 56 subungual glomus tumour was conducted from May 2010 to December 2021. Data with regard to gender, age at presentation, digit involved, presenting symptoms, duration of symptoms, clinical signs, need for MRI, anatomical location, surgical approach (longitudinal versus transverse), histopathology result, period of follow-up and complications were recorded. Results: All 56 (100%) patients presented with classic triad of symptoms. The average duration of symptoms was 52.9 months (range: 3-204 months). Eleven (20%) tumours were in the sterile matrix, 38 (68%) at the junction of sterile and germinal matrix and 7 (12%) in the germinal matrix. The tumours were excised through the longitudinal incision in 31 (55.3%) patients and transverse incision in 25 (44.7%). One (1.8%) tumour was intraosseous that was diagnosed intraoperatively and excised successfully. Average follow-up was 35.4 months (range: 6-120 months). There was no difference in outcomes (pain or nail deformity) between the two incisions. One patient (1.8%) has persistent pain that was due to a missed satellite lesion in the same digit. This was excised later with resolution of symptoms. There were no recurrences and all patients were cured after excision of tumour. Conclusions: Diagnosis of glomus tumour is usually clinical, and most are located at junction of sterile and germinal matrix. Tumour can be excised either by longitudinal or transverse nail bed incisions without any change of treatment outcome. Level of Evidence: Level IV (Therapeutic).

EXPERIENCES OF PACIFIC PATIENTS SEEKING ARTHROPLASTY IN NEW ZEALAND

Pacific people in New Zealand experience significant disparity in health outcomes. There is little known about the burden of arthritis within this community or difficulties accessing specialist orthopaedic care. This qualitative study evaluated the experiences of Pacific patients who underwent hip or knee arthroplasty with a goal to identify barriers to accessing arthroplasty for this community.We interviewed Pacific patients within the Bay of Plenty region who had received either elective hip or knee arthroplasty between 2013 and 2022. Interviews were centred on perceptions of arthritis severity, duration of symptoms, primary care and specialist interactions. Patients were encouraged to offer feedback on ways to improve this experience.We identified 6087 publicly funded primary joints performed in Tauranga hospital and 58 patients were of Pacific ethnicity. After exclusion criteria was applied, we successfully interviewed 20 patients eligible for our study. Pacific patients represented 2.9% of the of the BOP catchment but only received 0.43% of the publicly funded joints. Most reported reluctance to seek help from primary care until symptoms were present for at least a year. Most commonly cited reasons for not seeking help were fear of hospital services and lack of awareness in the community about osteoarthritis.We identified a lack of community awareness of osteoarthritis and arthroplasty among Pacific. This may result in delayed presentation to primary care and decreased utilisation of publicly funded joint surgery. It is reassuring that most patients of Pacific ethnicity who receive primary hip or knee arthroplasty report a positive experience. Public health initiatives together with positive feedback from Pacific patients who have undergone surgery will help to increase awareness of arthroplasty as an option to restore function and relieve pain.

Clinical and laboratory profiles of systemic lupus erythematosus patients in a new rheumatology clinic in southwestern Nigeria

IntroductionThe aims were to study the sociodemographic characteristics of patients presenting to the clinic and to study the clinical and serological pattern of systemic lupus erythematosus (SLE) in a new rheumatology clinic of a predominantly Yoruba population.Material and methodsThis was a retrospective, cross-sectional study conducted over 7 years (January 2017 – December 2023). Patients who satisfied the 1997 American College of Rheumatology (ACR) and/or the 2012 Systemic Lupus International Collaborating Clinics (SLICC) classification criteria were enrolled using their medical records. Patients with overlap syndromes and other inflammatory or noninflammatory rheumatic diseases were excluded from the study. Their sociodemographic, clinical, laboratory, and treatment data were retrieved from their medical records and analysed using IBM SPSS version 23.0 software.ResultsA total of 65 patients were diagnosed with SLE with a frequency of 15.8%. The mean age ±SD of the patients at presentation was 33.85 years ±11.01 and the female to male ratio was 9.8 : 1. The median (IQR) duration of symptoms at presentation was 7.0 months (3–24). The common clinical presentations included synovitis (86.2%), acute cutaneous rash (53.8%), oral ulcers (52.3%), nonscarring alopecia (50.8%), and serositis (47.7%). Proteinuria was seen in 37.7% of the patients and the predominant renal histopathological feature was Class IV. Antinuclear antibody was 100% positive with 50.94% of the patients having a titre of 1 : 5,120 and above. Anti- double-stranded deoxyribonucleic acid and anti-Smith antibodies each had 50% prevalence. Dyslipidaemia was found in 76.7% of the patients.ConclusionsThe study’s findings are largely consistent with similar studies done in Africa. Further prospective multi-centred studies are needed to further determine the epidemiological characteristics of the disease in Nigeria with a multi-ethnic population.

Brain structure comparison among Parkinson disease, essential tremor, and healthy controls using 7T MRI.

Both Parkinson disease (PD) and Essential tremor (ET) are movement disorders causing tremors in elderly individuals. Although PD and ET are different disease, they often present with similar initial symptoms, making their differentiation challenging with magnetic resonance imaging (MRI) techniques. This study aimed to identify structural brain differences among PD, ET, and health controls (HCs) using 7-Tesla (T) MRI. We assessed the whole-brain parcellation in gray matter volume, thickness, subcortical volume, and small regions of basal ganglia in PD (n = 18), ET (n = 15), and HCs (n = 18), who were matched for age and sex. Brain structure analysis was performed automatic segmentation through Freesurfer software. Small regions of basal ganglia were manually segmented by ITK-SNAP. Additionally, we examined the associations between clinical indicators (symptom duration, unified Parkinson diseases rating scale (UPDRS), and clinical rating scale for tremor (CRST)) and brain structure. PD showed a significant reduction in gray matter volume in the postcentral region compared to ET. ET showed a significant reduction in cerebellum volume compared to HCs. There was a negative correlation between CRST scores (B and C) and gray matter thickness in right superior frontal in ET. This study demonstrated potential of 7T MRI in differentiating brain structure differences among PD, ET, and HCs. Specific findings, such as parietal lobe atrophy in PD compared to ET and cerebellum atrophy in ET compared to HCs, the importance of advanced imaging techniques in accurately diagnosing and distinguishing between movement disorders that present with similar initial symptoms.

High Prevalence of Psychological Comorbidities and Functional Neurological Symptoms in Women With Urinary Retention.

Chronic idiopathic urinary retention (CIUR) in young women is poorly understood and a probable etiology is established only in around 40%, most commonly a primary disorder of external urethral sphincter relaxation, sometimes referred to as Fowler's syndrome. A high prevalence of psychological and functional comorbidities is reported, however these have been poorly characterized. Women consecutively referred for the assessment and management of CIUR were evaluated cross-sectionally for 13 psychological/behavioral domains using a structured clinical interview: depression, anxiety, post-traumatic stress disorder (PTSD), other psychiatric history, functional neurological disorder, other functional syndromes, childhood and adult trauma, personality disorder, and self-harm (ever/current). A total of 91 women (mean age [SD]: 34 [11] years) were evaluated. Women with Fowler's syndrome (n = 69) were younger (mean age [SD]: 32 [9] vs 40 [13] years) than women without Fowler's syndrome and reported shorter mean duration of urinary symptoms (mean [SD]: 5 [6] vs 10 [9]). A high prevalence of psychiatric and psychological comorbidities was reported (97%) including current depression (77%), current anxiety (78%), and PTSD (32%). A high prevalence of functional neurological disorder (56%) and other functional symptoms (65%) was also reported. Self-harm was reported in (14%) and personality disorder in 16%. Childhood trauma was reported in 35% of women. Young women with CIUR report a high burden of psychiatric disorders, affective symptoms, trauma, PTSD, self-harm, and functional neurological disorder, particularly in those with Fowler's syndrome. These factors can undermine the engagement with health care professionals and affect management and should therefore be addressed during the urological assessment.

Is endoscopic third ventriculostomy a viable treatment option for normal pressure hydrocephalus? A systematic review

Background: Endoscopic third ventriculostomy (ETV) is considered an alternative treatment for hydrocephalus and has become a standard of care for obstructive hydrocephalus. Recent studies have also explored its role in normal pressure hydrocephalus (NPH). We conducted a systematic review aiming to assess the outcomes of this minimally invasive endoscopic technique as a viable treatment option for NPH. Methods: A systematic literature search was performed using PubMed and Scopus databases, using iterations of search terms “Endoscopic third ventriculostomy,” “Idiopathic normal pressure hydrocephalus,” and “Normal pressure hydrocephalus.” To be eligible for inclusion in the review, articles had to report the usage of ETV as a primary treatment modality for NPH, report its outcomes, and be published in the English language. Results: Out of the 13 studies selected for qualitative synthesis, nine supported the use of ETV for NPH as an effective treatment option with improvement in the preoperative symptoms. Two studies favored shunt over ETV, stating that quality of life is better with VP shunt insertion. One study reported that ETV has higher perioperative mortality rates that outweigh its benefits. One study reported it to be an ineffective surgical option. Conclusion: The current review of evidence does not support the use of ETV for the treatment of NPH, except perhaps in a small subset of patients. These patients have a shorter duration of symptoms and a better preoperative neurological status. The lumbar infusion test and ventricular infusion test are modalities useful for selecting these candidates.

Tinnitus: an underreported condition following microvascular decompression for hemifacial spasm

PurposeWhile hearing loss is a well-known condition following microvascular decompression (MVD) for hemifacial spasm (HFS), tinnitus is an underreported one. This study aims to identify prevalence, characteristics, severity, and predictors of tinnitus following MVD for HFS.MethodsA single-center cohort of 55 HFS patients completed a questionnaire approximately 5 years following MVD. Data encompassed tinnitus presence, side, type, onset, and severity measured by a 10-point Visual Analogue Scale (VAS). Descriptive, correlation, and logistic regression analyses were conducted.Results At surgery, participants’ median age was 58 years (IQR 52–65). The median duration of HFS symptoms before surgery was 5 years (IQR 3–8), slightly predominant on the left (60%). Postoperative tinnitus was reported by 20 patients (36%), versus nine (16%) that reported preoperative tinnitus. Postoperative tinnitus was ipsilateral on the surgical side in 13 patients (65%), bilateral in six (30%), and contralateral in one (5%). Among patients with bilateral postoperative tinnitus, 33% did not have this preoperatively. Tinnitus was continuous in 70% of cases and pulsatile in 30%. Onset of new tinnitus was in 58% immediately or within days, in 25% within three months, and in 17% between three months and one year after surgery. The mean severity of postoperative tinnitus was 5.1 points on the VAS. Preoperative tinnitus and presence of arachnoid adhesions had suggestive associations with postoperative tinnitus in initial analyses (p = 0.005 and p = 0.065). However, preoperative tinnitus was the only significant predictor of postoperative tinnitus (p = 0.011).ConclusionTinnitus is a common condition following MVD for HFS, with a moderate overall severity. Causes behind postoperative tinnitus remain obscure but could be related to those of postoperative hearing loss in this patient population. Clinicians should be aware of tinnitus following MVD and vigilantly monitor its occurrence, to facilitate prevention efforts and optimize outcome for HFS patients undergoing MVD.

Covid-19 A Comprehensive Review of Signs, Symptoms, Diagnosis, and Treatment Strategies

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has significantly impacted global health. This review aims to provide a comprehensive overview of the signs, symptoms, diagnosis, and treatment modalities of COVID-19. The clinical presentation of COVID-19 varies widely, ranging from asymptomatic or mild symptoms to severe respiratory distress and multiorgan failure. Common symptoms include fever, cough, fatigue, and dyspnea, with less frequent symptoms such as anosmia, ageusia, and gastrointestinal symptoms. Diagnosis primarily relies on reverse transcription-polymerase chain reaction (RT-PCR) testing of respiratory specimens. However, imaging modalities such as chest X-ray and Antibody Test Antigen test in diagnosis, especially in cases with atypical presentations. Treatment strategies include supportive care, antiviral therapy, and, in severe cases, and other intensive care measures. The development and distribution of vaccines have been pivotal in controlling the spread of the virus. Despite significant progress in understanding and managing COVID-19, ongoing research is crucial to refine diagnostic strategies, develop effective therapies, and improve patient outcomes. Antiviral drugs, such as remdesivir, poxolovid, molonupiravir, have been widely used to inhibit viral replication and reduce the severity and duration of symptoms. Immunomodulators, including tocilizumab have been used to target specific pathways involved in the hyperinflammatory response seen in severe COVID-19. Monoclonal antibodies, such as casirivimab/imdevimab and sotrovimab, have been employed for passive immunization to neutralize the virus and reduce the risk of severe disease progression

Characterization of treatment resistance and viral kinetics in the setting of single- versus dual-active monoclonal antibodies against SARS-CoV-2.

Monoclonal antibodies (mAbs) represent a crucial antiviral strategy for SARS-CoV-2 infection, but it is unclear whether combination mAbs offer a benefit over single-active mAb treatment. Amubarvimab and romlusevimab significantly reduced the risk of hospitalizations or death in the ACTIV-2/A5401 trial. Certain SARS-CoV-2 variants are intrinsically resistant against romlusevimab, leading to only single-active mAb therapy with amubarvimab in these variants. We evaluated virologic outcomes in individuals treated with single- versus dual-active mAbs. Participants were non-hospitalized adults at higher risk of clinical progression randomized to amubarvimab plus romlusevimab or placebo. Quantitative SARS-CoV-2 RNA levels and targeted S gene next-generation sequencing was performed on anterior nasal samples. We compared viral load kinetics and resistance emergence between individuals treated with effective single- versus dual-active mAbs depending on the infecting variant. Study participants receiving single- and dual-active mAbs had similar demographics, baseline nasal viral load, symptom score, and symptom duration. Compared to single-active mAb, treatment with dual-active mAbs led to faster viral load decline at study day 3 (p < 0.001) and day 7 (p < 0.01). Treatment-emergent resistance mutations were more likely to be detected after amubarvimab plus romlusevimab treatment than placebo (2.6% vs 0%, P < 0.001), and more frequently detected in the setting of single-active compared to dual-active mAb treatment (7.2% vs 1.1%, p < 0.01). Single-active and dual-active mAb treatment resulted in similar decrease in rates of hospitalizations or death. Compared to single-active mAb therapy, dual-active mAbs led to similar clinical outcomes, but significantly faster viral load decline and a lower risk of emergent resistance.

The association of symptomatic vitreous floaters with depression and anxiety.

To evaluate the levels of anxiety and depression in patients with symptomatic vitreous floaters and to determine the possible correlations of psychological implications with the symptoms duration and possible improvement, the degree of posterior vitreous detachment, and the discomfort severity. Ninety patients complaining for floaters and fifty-seven age- and gender-matched healthy-control subjects were recruited. Every participant underwent a complete ophthalmological examination, including funduscopy and optical coherence tomography scans, while clinical and demographic data were also gathered. The Patient Health Questionnaire-9 (PHQ-9), the Zung Depression Inventory-Self-Rating Depression Scale (Zung SDS), and the Hospital Anxiety and Depression Scale (HADS) were completed by everyone. Between the studied groups, no significant differences were detected regarding the clinical and demographic data (p > 0.05). The patients with floaters had significantly higher scores of PHQ-9, Zung SDS, HADS Anxiety, and HADS Depression (p < 0.001). After adjustment for several confounders, PHQ-9 (p = 0.041), Zung SDS (p = 0.003), and HADS Anxiety (p = 0.036) values remained significantly impaired. Among the patients, PHQ-9 and Zung SDS scores were significantly elevated in the patients with floaters duration less than 4weeks (p < 0.05). Finally, anxiety and depression were significantly correlated with the symptoms duration and intensity, with the floater-associated discomfort, and with the stage of posterior vitreous detachment. Vitreous floaters have a negative impact on patients' psychological status, by the terms of enhanced depressive and anxiety levels. To the best of our knowledge, our study is the first in the literature to elaborate the aforementioned association, by assessing three different questionnaires simultaneously.

Proximal Medial Gastrocnemius Recession for Recalcitrant Plantar Fasciitis.

Recalcitrant plantar fasciitis (RPF) is characterized by its unresponsiveness to conservative treatments, and its surgical management remains controversial. Although there is some evidence to suggest that gastrocnemius recession can be an effective treatment for RPF, no large series of patients with mid- to long-term follow-up has been published. The objective of this study was to compare physical performance, as measured by the Foot and Ankle Ability Measure activities of daily living score (FAAM-ADL), and pain levels before and 1 year after undergoing proximal medial gastrocnemius recession (PMGR) as a treatment for RPF. Additionally, we aimed to assess this cohort of patients in the mid- to long-term follow-up. This retrospective cohort study included 167 patients who underwent PMGR to address RPF between 2009 and 2021. Patients were examined with the FAAM ADL, visual analog scale (VAS) and satisfaction scores at baseline, 1 year, and at the end of follow-up. Other variables recorded were weight, duration of symptoms until surgery, time between surgery to substantial clinical improvement, calf power and Silfverskiold test, and postoperative complications. We observed that before surgery patients had an FAAM-ADL score of 22.5 (SD 11.1) and a VAS score of 8.6 (SD 9.3). One year after surgery, patients had an FAAM-ADL score of 89 (SD 17) and VAS of 1.33 (SD 2) (P < .01). We also observed that the FAAM-ADL score in the long-term follow-up (>12.5 years) group had a median of 86.4 (SD 22.6), the VAS score was 1.90 (SD 2.84), and the patient satisfaction score had a median of 1 (interquartile range 0-1). Regarding complications, we observed 1 lateral gastrocnemius recession and 1 sural nerve neuritis. Our study provides substantial evidence supporting the use of PMGR as an effective treatment for RPF. The long-term follow-up and large sample size of our series contribute to the existing literature on this topic. Level IV, case series.

Developing and validating a nomogram for early predicting the need for intestinal resection in pediatric intussusception

PurposeDevelop and validate a nomogram for predicting intestinal resection in pediatric intussusception suspecting intestinal necrosis.Patients &amp;amp; methodsChildren with intussusception were retrospectively enrolled after a failed air-enema reduction in the outpatient setting and divided into two groups: the intestinal resection group and the non-intestinal resection group. The enrolled cases were randomly selected for training and validation sets with a split ratio of 3:1. A nomogram for predicting the risk of intestinal resection was visualized using logistic regression analysis with calibration curve, C-index, and decision curve analysis to evaluate the model.ResultsA total of 547 cases were included in the final analysis, of which 414 had non-intestinal necrosis and 133 had intestinal necrosis and underwent intestinal resection. The training set consisted of 411 patients and the validation cohort included 136 patients. Through forward stepwise regression, four variables (duration of symptoms, C-reaction protein, white blood cells, ascites) were selected for inclusion in the nomogram with a concordance index 0.871 (95% confidence interval: 0.834–0.908).ConclusionWe developed a nomogram for predicting intestinal resection in children with intussusception suspecting intestinal necrosis after a failed air-enema based on multivariate regression. This nomogram could be directly applied to facilitate predicting intestinal resection in pediatric intussusception suspecting necrosis.

Duration and severity of COVID-19 symptoms among primary healthcare workers: A cross-sectional survey.

This study aims to investigate the epidemiological characteristics of COVID-19 infection among healthcare workers, including the severity, duration of infection, post-infection symptoms and related influencing factors. A self-administered questionnaire was utilized to assess the post-infection status of primary healthcare workers in Jiangsu Province. The questionnaire collected information on demographic characteristics, lifestyle habits, post-infection clinical manifestations, work environment and recovery time of the respondents. Customized outcome events were selected as dependent variables and logistic regression models were employed to analyse the risk factors. Phi-coefficient was used to describe the relationship between post-infection symptoms. The analysis revealed that several factors, such as female, older age, obesity, previous medical history, exposure to high-risk environments and stress, were associated with a higher likelihood of experiencing more severe outcomes. On the other hand, vaccination and regular exercise were found to contribute to an earlier resolution of the infection. Among the post-infection symptoms, cough, malaise and muscle aches were the most frequently reported. Overall, there was a weak association among symptoms persisting beyond 14 days, with only cough and malaise, malaise and dizziness and headache showing a stronger correlation. The study findings indicate that the overall severity of the first wave of infection, following the complete lifting of restrictions in China, was low. The impact on primary healthcare workers was limited, and the post-infection symptoms exhibited similarity to those observed in other countries. It is important to highlight that these conclusions are specifically relevant to the population infected with the Omicron variant. This study helps to grasp the impacts of the first wave of COVID-19 infections on healthcare workers in China after the national lockdown was lifted. Primary healthcare workers in Jiangsu Province, including doctors, nurses, pharmacists and other personnel from primary healthcare units such as community health service centres and health centres.

No safe time window in malrotation and volvulus: A consecutive cohort study.

Malrotation and volvulus classically present with bilious vomiting. It is more common earlier in life, but there are other causes of bile-stained vomiting. This leads some clinicians to 'watch and wait'. In the presence of a volvulus, this is potentially a fatal decision. It is not clear from the literature if there is a safe time window in which children can be observed in the hope of avoiding transfers or radiological investigations. To determine whether time to identification and management of midgut volvulus correlated with morbidity and mortality; and whether there were patterns to transition of care. Multicentre, retrospective review of all children with malrotation ± volvulus at two tertiary children's hospitals in Brisbane from 2000 to 2012. Data collected included age at presentation, timing between symptom onset and presentation, radiological findings, and definitive surgical management. Outcomes included patient length of stay (LOS), total parenteral nutrition (TPN) duration, re-operations and death. There were 96 cases of malrotation identified, with 23 excluded (elective operation, insufficient data). Neonates made up 66% of included cases. Only 14% of cases were over 12 months old. Bilious vomiting or bile-stained aspirates were the presenting symptoms in 71% (52). Overall mortality was 5.56%. Time from symptom onset to presentation or management was not significantly associated with morbidity or mortality. More than half (53%, 39/73) of patients received total parenteral nutrition; 20/39 for more than 10 days. Neonates and infants had a significantly higher rate of TPN compared with older children (P < 0.001). Those requiring TPN post-operatively had a significantly higher mortality compared with those who did not (P = 0.02). Time from symptom onset to presentation or definitive management was not significantly associated with LOS, TPN duration, or need for re-operation. Malrotation remains a time-critical diagnosis to secure and treat. Even a short duration of symptoms can be associated with high morbidity or mortality. There is no place for 'watch and wait' for such patients, and malrotation/volvulus should be emergently actively excluded with contrast studies.

Skull Base CSF Leaks: Potential Underlying Pathophysiology and Evaluation of Brain MR Imaging Findings Associated with Spontaneous Intracranial Hypotension.

Cerebrospinal fluid (CSF) leaks of the skull base and spine share a common process of CSF volume loss, and yet only the latter has been associated with spontaneous intracranial hypotension (SIH). Despite published claims that only spinal leaks cause SIH, no prior studies have evaluated brain MR imaging in patients with skull base leaks for findings associated with SIH such as dural enhancement. The purpose of our study was to use a validated brain MR imaging scoring system to evaluate skull base CSF leak patients for findings associated with SIH. We included patients with confirmed skull base CSF leaks and contrast enhanced pre-operative brain MRI. The pre-operative MR images were reviewed for findings associated with SIH using the Bern score. Patient age, presenting symptoms and their duration, and leak site were also recorded. 31 patients with skull base CSF leaks were included. Mean Bern score was 0.9 (range 0-4, SD 1.1), and only 1 patient (3%) had dural enhancement. Mean age was 53 years (range 18-76). Mean symptom duration was 1.3 years, with 22 patients presenting within one year of symptom onset. 23 patients (74.2%) had intraoperative confirmation of leak from the middle cranial fossa, involving the temporal bone, while 7 (22.6%) had leaks from the anterior skull base. One patient, who had dural enhancement, had an infratentorial CSF leak along the petrous segment of the internal carotid artery. Our study provides further evidence that skull base and spinal CSF leaks represent distinct pathophysiologies and present with different brain MRI findings.ABBREVIATIONS: SIH = Spontaneous Intracranial Hypotension; IIH = Idiopathic Intracranial Hypertension.

Non-Invasive Ventilation Support during Hospitalization for SARS-CoV-2 and the Risk of Venous Thromboembolism

Background/Objectives: Although SARS-CoV-2 infection is a significant risk factor for venous thromboembolism (VTE), data on the impact of the use of non-invasive ventilation support (NIVS) to mitigate the risk of VTE during hospitalization are scarce. Methods: Data for 1471 SARS-CoV-2 patients, hospitalized in a single hub during the first pandemic wave, were collected from clinical records, including symptom duration and type, information on lung abnormalities on chest computed tomography (CT), laboratory parameters and the use of NIVS. Determining VTE occurrence during hospital stays was the main endpoint. Results: Patients with VTE (1.8%) had an increased prevalence of obesity (26% vs. 11%), diabetes (41% vs. 21%), higher CHA2DS2VASC score (4, IQR 2–5 vs. 3, IQR 1–4, age- and sex-adjusted, p = 0.021) and cough (65% vs. 44%) and experienced significantly higher rates of NIVS (44% vs. 8%). Using a stepwise multivariate logistic regression model, the prevalence of electrocardiogram abnormalities (odds ratio (OR) 2.722, 95% confidence interval (CI) 1.039–7.133, p = 0.042), cough (OR 3.019, 95% CI 1.265–7.202, p = 0.013), CHA2DS2-VASC score &gt; 3 (OR 3.404, 95% CI 1.362–8.513, p = 0.009) and the use of NIVS (OR 15.530, 95% CI 6.244–38.627, p &lt; 0.001) were independently associated with a risk of VTE during hospitalization. NIVS remained an independent risk factor for VTE even after adjustment for the period of admission within the pandemic wave. Conclusions: Our study suggests that NIVS is a risk factor for VTE during hospitalization in SARS-CoV-2 patients. Future studies should assess the optimal prophylactic strategy against VTE in patients with a SARS-CoV-2 infection candidate to non-invasive ventilatory support.
