Three twisted tales: A case series of caecal volvulus

IntroductionCaecal volvulus is a form of intestinal obstruction with life-threatening potential. While rare, it represents a perilous aetiology of intestinal blockage, with clinical manifestations spanning from abdominal discomfort to mortality. Case seriesWe report the cases of three young adults (two males and one female) who presented to the emergency department with different manifestations of severe abdominal pain. All occurred within one month in a tertiary referral centre. Radiological evaluations confirmed the diagnosis of caecal volvulus in all. Subsequently, these individuals underwent right hemicolectomies with end-to-end anastomosis. All experienced an uncomplicated perioperative course. Clinical discussionCaecal volvulus is uncommon, but its yearly incidence is increasing. Early detection and a heightened level of suspicion lead to a timely diagnosis, reducing morbidity and mortality rates. ConclusionWe report a case series of caecal volvulus, emphasizing its variable presentation and highlighting the critical importance of an early diagnosis. Typically, patients have a history of similar episodes that resolve without any medical intervention. Definitive treatment involves right hemicolectomy while conservative management is associated with very high recurrence rates. Early detection allows for prompt intervention, resulting in reduced morbidity and mortality rates.

Distinct features of ANCA-associated hypertrophic pachymeningitis compared to other etiologies: findings from a study of 74 patients.

We aimed to characterize the clinical and radiological features, and outcomes, of a large cohort of hypertrophic pachymeningitis (HP) patients from a single center. We conducted a retrospective study at a tertiary referral center, encompassing patients diagnosed with HP between 2003 and 2022. The diagnosis of HP relied on the identification of thickening of the dura mater via magnetic resonance imaging (MRI) of the brain or spine. We included 74 patients with a mean age of 43.6 ± 14.2 years, of whom 37 (50%) were male. Among them, 32 (43.2%) had an immune-mediated origin, including 21 with granulomatosis with polyangiitis (GPA) (predominantly PR3-ANCA positive), four with systemic lupus erythematosus, three with IgG4-related disease, three with idiopathic HP, and one with rheumatoid arthritis. Non-immune-mediated HP accounted for 45 cases (56.8%). Within this category, 21 (28.4%) were infectious cases, with 14 being Mycobacterium tuberculosis infection (TB-HP), and 21 (28.4%) were malignancy-associated HP. Clinical and MRI characteristics exhibited variations among the four etiological groups. Hypoglycorrhachia was primarily observed in infectious and malignancy-associated HP. Immune-mediated HP was associated with a peripheral pattern of contrast enhancement and the Eiffel-by-night sign. MRI features strongly indicative of TB-HP included leptomeningeal involvement, brain parenchymal lesions, and arterial stroke. MPO-ANCA GPA was associated with a higher prevalence of spinal HP. Within our cohort, GPA and Mycobacterium tuberculosis emerged as the predominant causes of HP. We identified significant disparities in clinical and radiological features among different etiologies, which could have implications for diagnosis.

Epidemiological Study of Pathogens in Spontaneous Bacterial Peritonitis in 2017-2024-A Preliminary Report of the University Hospital in South-Eastern Poland.

Spontaneous Bacterial Peritonitis (SBP) is a serious complication and a common cause of death in patients with liver cirrhosis. Between January 2017 and March 2024, a retrospective study was conducted involving 302 patients (>18 years old) with ascites treated at a tertiary referral center in south-eastern Poland. Microbiological analysis of the ascitic fluids was performed in all patients. The presence of microorganisms was found in samples from 17 patients, and 21 pathogens were isolated, including 15 Gram-positive bacteria and 6 Gram-negative bacteria. Staphylococcus epidermidis, MRCNS (methicillin-resistant coagulase-negative staphylococci, resistant to all beta-lactam antibiotics: penicillins, penicillins with beta-lactamase inhibitor, cephalosporins and carbapenems) was the main pathogen detected (19.05%, 4/21), followed by Enterococcus faecalis (9.52%, 2/21), Enterococcus faecium (9.52%, 2/21), Staphylococcus haemolyticus, MRCNS (4.76%, 1/21), Streptococcus mitis (9.52%, 2/21), Streptococcus parasanguinis (9.52%, 2/21), Micrococcus luteus (4.76%, 1/21) and Bacillus spp. (4.76%, 1/21). The following Gram-negative bacteria were also found in the specimens examined: Escherichia coli, ESBL (extended-spectrum β-lactamase producing E. coli) (4.76%, 1/21), Escherichia coli (4.76%, 1/21), Pseudomonas aeruginosa (4.76%, 1/21), Klebsiella oxytoca (9.52%, 2/21) and Sphingomonas paucimobilis (4.76%, 1/21). Gram-positive bacteria caused nosocomial infections in nine patients with SBP, Gram-negative bacteria caused nosocomial infections in two patients. In six patients with SBP, community-acquired infections caused by Gram-negative bacteria were found in three cases, Gram-positive bacteria in two cases, and in one case, community-acquired infection was caused by mixed Gram-positive and Gram-negative. Bacteria isolated from patients with hospital-acquired SBP showed higher drug resistance than those found in patients with non-hospital SBP. Bacterial infections in cirrhotic patients with complications may be responsible for their deteriorating health. Prompt intervention is critical to reducing mortality.

Incidence of incisional hernia in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: an observational clinical study from a tertiary oncology referral care center in India

BackgroundAn incisional hernia (IH) after major abdominal surgery is an unwanted complication particularly following cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS and HIPEC). The frequency of IH among patients treated with CRS and HIPEC remains unexpectedly high in various studies. This study aimed to analyze the incidence, determine the factors contributing to the occurrence of IH, and develop methods to reduce the incidence of IH.MethodsWe retrospectively analyzed data from a prospectively maintained structured computerized comprehensive database of 360 patients who had undergone CRS and HIPEC after January 2013 and completed two years of follow-up before December 2023. All patients were followed for a minimum period of two years with physical examination and radiological imaging when required and the occurrence of IH was documented. We used SPSS software version 24 to analyze the data using appropriate statistical tests. We set a significance threshold of p < 0.05.ResultsWithin two years of undergoing CRS and HIPEC, 25 patients (6.9%) out of 360 developed IH, indicating an annual incidence rate of 3.5%. The mean duration of hospitalization for the CRS/HIPEC procedure was 8.4 ± 4.13 days. Fifty-two (14.4%) patients experienced early post-operative surgical complications. The development of IH in our series was significantly associated with obesity (76% vs. 8.4%, P = 0.001), the occurrence of early post-operative surgical complications (48% vs. 12%, P = 0.001), mainly category III complications (44% vs. 7.1%), category IV complications (24% vs. 2.9%) according to Clavien-Dindo classification, post neoadjuvant chemotherapy status (72% vs. 87%, P = 0.045) and need for bowel anastomosis (32% vs. 11%, P = 0.002).ConclusionThe lower incidence of IH following CRS and HIPEC in our patient cohort than in the literature can be attributed to a combination of factors, including the use of meticulous surgical techniques and the use of an abdominal binder postoperatively, particularly in obese patients.

CARDIAC AMYLOIDOSIS IN ELDERLY WITH POSITIVE SCINTIGRAPHY AND MONOCLONALITY: A DIAGNOSTIC DILEMMA

Abstract Background and Aims Clinical identification of elderly patients with both wild–type transthyretin amyloidosis (ATTR) and monoclonal gammopathy of unknown significance (MGUS) is increasing. For this reason, accurate amyloid histologic subtyping is crucial in case of concomitant positivity of bisphosphonate scintigraphy and monoclonal protein testing. We report the diagnostic work–up of cardiac amyloidosis in this specific patient subtype in our tertiary referral center. Methods Among 133 patients who received the diagnosis of cardiac amyloidosis from March 2021 to March 2023, 21 (16%) presented with an abnormality of both bisphosphonate scintigraphy and at least one of the serum monoclonal protein tests. Patients underwent abdominal fat biopsy/needle aspiration as the first diagnostic procedure. In case of negative results, an endomyocardial biopsy (EMB) was planned. Amyloid was identified at histology by Congo Red staining. Amyloid typing was obtained by immunohistochemistry using a recently developed amyloid antibody panel AmYkit (Amimed) applicable on fixed paraffin–embedded tissues in an automated platform. The results were compared with those obtained with standard immunohistochemistry. Results Sixteen of the 21 patients were older than 75 years (76%, 81±10 ys) with a grade 3 (62%) or 2 (33%) scintigraphy. A grade 1 positive scintigraphy was detected in one patient. Serum immunofixation revealed a previously unknown monoclonal protein peak in 78%, while 22% had a history of MGUS. None of the patients had hematologic disorders. TTR pathogenic mutation was detected in one patient. On pathologic examination, abdominal fat was negative for amyloid in all cases, while Congo Red staining was positive in all examined EMBs. Immunohistochemistry performed with standard antibodies was not able to discriminate between AL and ATTR, due to signal overlapping of variable intensity. Conversely, our preliminary results with AmYkit panel of antibodies demonstrate absence of signal overlapping in over 90% of cases, allowing accurate histologic discrimination between AL and TTR. Conclusion Based on our clinical and histologic observations, in elderly patients with concomitant positivity of both bisphosphonate scintigraphy and monoclonal protein testing, TTR is the most frequent type of cardiac amyloid. EMB is a useful diagnostic tool to confirm the clinical suspicion of amyloidosis. Accurate amyloid subtyping is granted by a more sensitive panel of antibodies.

DIAGNOSTIC CRITERIA FOR NON–DILATED LEFT VENTRICULAR CARDIOMYOPATHY WITH PROGNOSTIC SIGNIFICANCE

Abstract Background Non–dilated left ventricular cardiomyopathy (NDLVC) is a novel diagnostic entity defined as non–ischemic LV scarring or fatty replacement regardless of the presence of global or regional wall motion abnormalities, or isolated global LV hypokinesia without scarring. While the absence of LV dilation and systolic dysfunction are implicit, no cut–offs were proposed. Methods All patients undergoing cardiac magnetic resonance (CMR) examination at a tertiary referral center from 2012 to 2022 and meeting the definition of NDLVC were evaluated. The primary endpoint was a composite of cardiac death, sustained ventricular tachycardia (VT) or ventricular fibrillation, appropriate defibrillator intervention; the secondary endpoint included also non–sustained VT. Results The cohort included 262 patients, with 176 men (67%) and a median age of 55 years (interquartile range 44–64 years). Patients without moderate (n=243, 93%) or severe LV dilation (n=249, 95%) had a longer survival free from both endpoints. The 50% LVEF threshold identified patients with different outcomes, whereas the 55% and 60% cut–offs did not. LVEF ≥50% and no severe LV dilation predicted a better outcome independent of percent LGE in the LV, the number of LV segments with LGE, LV fibro–fatty replacement, or right ventricular involvement. LVEF ≥50% and no severe LV dilation retained an independent prognostic value even in patients with LV LGE (80% of the whole cohort). Conclusions Excluding severe LV dilation (LVEDVi &amp;gt;129 mL/m2 in men and &amp;gt;116 mL/m2 in women) and LV dysfunction (LVEF &amp;lt;50%) could enhance the prognostic utility of the NDLVC definition.

Perspectives on sustainable practices in the use of nitrous oxide for labour analgesia: A patient and staff survey.

Climate change has emerged as the single biggest global health threat of the twenty-first century. Nitrous oxide accounts for the largest carbon footprint amongst our use of anaesthetic gas. It is a potent greenhouse gas possessing a global warming potential of approximately 265 times that of carbon dioxide. Despite recent curtailment of its use, it remains extensively employed as an analgesic for women in labour. Assessment of the opinions of post-natal women and staff on nitrous oxide use and to investigate whether knowledge of its environmental harm would influence their choice of labour analgesia. Postnatal women and healthcare staff were invited to participate in a survey of nitrous oxide use as a labour analgesic and knowledge of its effect of the environment. A single-centre study in a major obstetric tertiary referral centre in Ireland in 2021. To evaluate the awareness and perceptions of postnatal women and staff regarding the environmental impact of nitrous oxide and if it would affect their decision to use it in the future. One hundred postnatal women and 50 healthcare staff completed the survey. One hundred and six post-natal women were invited to complete the survey, resulting in a response rate of 94%. Knowledge of nitrous oxide's environmental impact was low. After receiving information, 46% of patients were more inclined to seek epidural or request it earlier (54%) to limit their nitrous oxide use, while 51% would choose an alternative analgesia to avoid nitrous oxide altogether. Overwhelmingly, 99% believed they had the right to know about these harmful effects when choosing an analgesic option. Patients should be informed of the environmental impact of nitrous oxide antenatally, empowering them to make informed decision on a climate friendly analgesic option if they wish.

Subcapital realignment osteotomy for the treatment of moderate and severe slipped upper femoral epiphysis: A retrospective study of 123 hips in a tertiary center

Background: The surgical treatment of moderate and severe slipped capital femoral epiphysis is controversial. Treatment ranges from pinning in situ to open dislocation and reduction of the slipped epiphysis. The modified Dunn procedure has been associated with variable avascular necrosis with rates, ranging between 0% and 67%. The aim of this study was to evaluate the outcomes and complications of patients who have undergone a subcapital realignment osteotomy (SCRO) in our center. Methods: A retrospective longitudinal study of the osteotomies performed between 2009 and 2019 in a tertiary referral center for Pediatric Orthopedics in Queensland, Australia. Patient demographics, stability, and severity of slip and surgical outcomes were collected. Results: A total of 123 procedures were performed on 116 patients. The mean age was 12.4 years, 65 (56%) patients were male and the mean posterior sloping angle was 60.10 with 93 (75%) being severe slips. There were 51 (41.5%) Loder’s stable and 72 (58%) unstable slipped capital femoral epiphysis. Our overall avascular necrosis rate following SCRO was 17.8%. Time between surgery and diagnosis did not have an effect on avascular necrosis. Conclusion: The subcapital realignment osteotomy remains a controversial and complex procedure for the management of moderate and severe slipped capital femoral epiphysis. We found that our cohort demonstrated an avascular necrosis rate in keeping with the existing literature. This indicates that when performed in a high-volume center with experienced surgical staff, it can be an effective treatment option for these patients. Level of evidence: Level IV

Validity of endoscopic ossiculoplasty immediately after its introduction for ossicular chain disruption

BackgroundTranscanal endoscopic ear surgery (TEES) reportedly requires a long learning curve and may be associated with more complications and longer operative times than microscopic ear surgery (MES). In this study, we aimed to examine the usefulness and validity of TEES for ossicular chain disruption in the early stages of its introduction in our institution.MethodsTEES was performed on 11 ears (10 with congenital ossicular chain discontinuity and 1 with traumatic ossicular chain dislocation), and MES was performed with a retroauricular incision on 18 ears (6 with congenital ossicular chain discontinuity and 12 with traumatic ossicular chain dislocation) in a tertiary referral center. Postoperative hearing results, operative times, and postoperative hospital length of stay were retrospectively reviewed. The Mann–Whitney U test and Fisher’s exact test was performed to compare variables between the TEES and MES groups. Pre- and postoperative air- and bone-conduction thresholds and the air–bone gap of each group were compared using the Wilcoxon signed-rank test. The Mann–Whitney U test and Wilcoxon signed-rank was performed to compare the pre- and postoperative air–bone gaps between the diagnoses.ResultsNo significant differences in the postoperative air-conduction thresholds, bone-conduction thresholds, air–bone gaps, or incidence of air–bone gap ≤ 20 dB were observed between the TEES and MES groups. The air-conduction thresholds and air–bone gaps of the TEES group significantly improved postoperatively. The air-conduction thresholds and air–bone gaps of the MES group also significantly improved postoperatively. No significant difference was observed in the operative times between the groups (TEES group: median, 80 min; MES group: median, 85.5 min). The TEES group had a significantly shorter postoperative hospital stay (median, 2 days) than the MES group (median, 7.5 days).ConclusionsTEES was considered appropriate for the treatment of ossicular chain disruption, even immediately after its introduction at our institution. For expert microscopic ear surgeons, ossicular chain disruption may be considered a suitable indication for the introduction of TEES.

Progression of adenomyosis: Rate and associated factors.

To evaluate the rate of disease progression and the factors associated with such progression in patients with an ultrasound diagnosis of adenomyosis. This was a single center, prospective, observational, cohort study performed at a tertiary referral center. Patients who obtained an ultrasound diagnosis of adenomyosis from May 2022 to August 2022 were recruited. Demographic, clinical and ultrasound data were recorded at the first visit (T0) and after 12 months (T1) for enrolled patients and compared between T0 and T1. The study population was divided in two groups according to progression (increase in uterine volume >20%) or stability/regression (decrease or increase in uterine volume ≤20%) of adenomyosis at T1. Primary study outcome was the rate of adenomyosis progression, while secondary study outcome was the association of adenomyosis progression with demographic and clinical factors. Post hoc subgroups analyses for primary and secondary study outcomes were performed based on hormonal therapy (untreated and treated). A total of 221 patients were enrolled in the study, with no significant difference in terms of baseline data among the two study groups and no patients were lost to follow-up. The overall rate of adenomyosis progression was 21.3% (47/221 patients). The rate was 30.77% in hormonally untreated women, and 18.34% in hormonally treated women. Progression was associated with the presence of focal adenomyosis of the outer myometrium (P = 0.037), moderate to severe dysmenorrhea (P = 0.001), chronic pelvic pain (P = 0.05), dyschezia (P = 0.05), and worsening of chronic pelvic pain (P = 0.04) at T1. Adenomyosis showed a rate of disease progression of 21.3% at the 12-month follow-up (30.77% in hormonally untreated women, and 18.34% in hormonally treated women). The presence and/or worsening of painful symptoms, such as severe dysmenorrhea, dyschezia and chronic pelvic pain, as well as the presence focal adenomyosis of the outer myometrium, might help identify patients at higher risk of disease progression and tailor their follow-up.

Efficacy of different indocyanine green doses in fluorescent laparoscopic cholecystectomy: A prospective, randomized, double-blind trial.

Intraoperative bile duct injury is a significant complication in laparoscopic cholecystectomy (LC). Near-infrared fluorescence cholangiography (NIFC) can reduce this complication. Therefore, determining the optimal indocyanine green (ICG) dosage for effective NIFC is crucial. This study aimed to determine the optimal ICG dosage for NIFC. This was a prospective, randomized, double-blind clinical trial at a single tertiary referral center, including 195 patients randomly assigned to three groups: lower dose (0.01 mg/BMI) ICG (n = 63), medium dose (0.02 mg/BMI) ICG (n = 68), and higher dose (0.04 mg/BMI) ICG (n = 64). Surgeon satisfaction and detection rates for seven biliary structures were compared among the three dose groups. Demographic parameters did not significantly differ among the groups. The medium dose (72.1%) and higher dose ICG groups (70.3%) exhibited superior visualization of the common hepatic duct compared to the lower dose group (41.3%) (p < 0.001). No differences existed between the medium and higher dose groups. Similar trends were observed for the common bile duct and cystic common bile duct junction. In patients undergoing fluorescent laparoscopic cholecystectomy, the 0.02 mg/BMI dose of indocyanine green demonstrated better biliary structure detection rates than the 0.01 mg/BMI dose and was non-inferior to the 0.04 mg/BMI dose.

Female non-obstetric urogenital fistula repair: long-term patient-reported outcomes and a scoping literature review.

To investigate long-term and patient-reported outcomes, including sexual function, in women undergoing urogenital fistula (UGF) repair, addressing the lack of such data in Western countries, where fistulas often result from iatrogenic causes. We conducted a retrospective analysis at a tertiary referral centre (2010-2023), classifying fistulas based on World Health Organisation criteria and evaluating surgical approaches, aetiology, and characteristics. Both objective (fistula closure, reintervention rates) and subjective outcomes (validated questionnaires) were assessed. A scoping review of patient-reported outcome measures in UGF repair was also performed. The study included 50 patients: 17 (34%) underwent transvaginal and 33 (66%) transabdominal surgery. History of hysterectomy was present in 36 patients (72%). The median (interquartile range [IQR]) operating time was 130 (88-148) min. Fistula closure was achieved in 94% of cases at a median (IQR) follow-up of 50 (16-91) months and reached 100% after three redo fistula repairs. Seven patients (14%) underwent reinterventions for stress urinary incontinence after transvaginal repair (autologous fascial slings). Patient-reported outcomes showed median (IQR) scores on the International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms Modules (ICIQ-FLUTS) of 5 (3-7) for filling symptoms, 1 (0-2) for voiding symptoms and 4.5 (1-9) for incontinence symptoms. The median (IQR) score on the ICIQ Female Sexual Matters Associated with Lower Urinary Tract Symptoms Module (ICIQ-FLUTSsex) was 3 (1-5). The median (IQR) ICIQ Satisfaction (ICIQ-S) outcome score and overall satisfaction with surgery item score was 22 (18.5-23.5) and 10 (8.5-10), respectively. Higher scores indicate higher symptom burden and treatment satisfaction, respectively. Our scoping review included 1784 women, revealing mixed aetiology and methodological and aetiological heterogeneity, thus complicating cross-study comparisons. Urogenital fistula repair at a specialised centre leads to excellent outcomes and high satisfaction. Patients with urethrovaginal fistulas are at increased risk of stress urinary incontinence, possibly due to the original trauma site of the fistula.

Life on the line - Incidence and management of central venous catheter complications in intestinal failure

Background & AimsLoss of venous access is threatening for patients with intestinal failure (IF) under long-term parenteral nutrition (PN). We aimed to identify the incidence of central venous catheter (CVC) complications, compare different devices, and analyze interventional recanalizing procedures to restore the patency of occluded CVCs. MethodsFor this retrospective cohort study, patient data from a prospective IF database spanning 16 years was analyzed at a tertiary referral center. Catheter dwell times (CDT) were distinguished by Kaplan-Meier survival analysis and subgroup analyses were performed for different CVC types (tunneled/ port catheters). Specific complications (occlusion, catheter-related infection (CRI), displacement, and material defect) were analyzed. Explantation rates and CDT were compared. ResultsOverall, 193 CVCs in 77 patients with IF under PN could be enrolled (62.524 “CVC-days”). Broviac type “B” was found to be significantly superior to type “A” regarding occlusion, CRI, and material defects (log-rank test: p=0.05; p=0.026; p=0.005 respectively). Port catheters were displaying the highest incidence of CRI (2.13 events/1000 catheter days). Interventional catheter recanalization was performed 91 times and significantly increased the CDT from a median of 131 days (IQR: 62; 258) to 388.5 days (IQR: 262; 731) (Mann-Whitney-U-test: p= <0.001) without increasing complications. ConclusionsDifferent complication rates and CDT were seen depending on CVC type. Tunneled catheters were significantly superior concerning CRI. Interventional catheter recanalization is a viable alternative to fibrinolytics to restore CVC patency, but long-term patency data is scarce.

The safety and efficacy of TNF inhibitors in patients with Behçet's disease: Retrospective study from eastern Turkey

ObjectiveWe aimed to evaluate the clinical features, disease course, and associated factors for outcome in severe/refractory BD patients receiving TNF-i treatment. Material and methodsThis retrospective study was conducted by reviewing medical records from a tertiary referral center in Van province in Eastern Turkey. Data were obtained from patients' charts followed up between June 2019 and June 2022. ResultsWe included 469 BD patients (59.3% male) whose 80 patients (17%) received TNF-i treatment in the study. The mean ± standard deviation of the patient age was 36.7 ± 10.1 years and the median (IQR) disease duration was 12 (12) years. IFX and ADAwere initiated in 67.5% (n = 54) and 32.5% (n = 26) patients, respectively. Overall and first-line retention rates of TNF-i were 84.7% and 92.6% for IFX and 83.3% and 80.8% for ADA, respectively. IFX was discontinued in 9 patients which were in 2 patients due to allergic reaction and tuberculosis, 3 patients for inefficacy, one patient for heart failure, and one patient for orbital zona. Although no serious adverse event was observed with ADA, 5 patients switched to IFX due to inefficacy. Overall, 72 patients (90%) resumed TNF-i at the end of the study; TNF-i was discontinued in 3 patients (3.8%) due to severe adverse events and in 5 patients (6.2%) with prolonged remission. ConclusionIn our study, no case of death was observed in TNF-i receiving patients. Most patients achieved attack-free and CS-free disease and retained TNF-i treatment. TNF inhibitors appear to be safe and effective in patients with severe/refractory Behçet's disease.

Prognosis of type A acute aortic syndrome in elderly patients

Abstract Funding Acknowledgements None. Introduction Type A acute aortic syndrome (AAS-A) is associated with a high mortality. Emergent surgery is the treatment of choice for patients with AAS-A. However, this surgery is a highly complex procedure associated with a significant morbidity. There are uncertainties about the best treatment strategy for elderly patients, which pose a challenge in clinical practice. Purpose The aim of this study is to evaluate the prognosis of elderly patients with AAS-A and to analyse the impact and outcome of surgery in this patient population. Methods Patients with AAS-A were prospectively and consecutively collected from April-2019 to March-2023 in a four-hospital network with a tertiary care referral centre for cardiac surgery. Patients were classified according to age into two groups: ≥75 years and under 75 years. Clinical, diagnostic, treatment and prognostic variables were analysed. Results A total of 113 patients with AAS were included, of whom 82 were AAS-A patients. Of these, 27 were aged 75 years or older. Older patients had more comorbidities: COPD, atrial fibrillation, renal failure and stroke (table). Elderly patients were diagnosed later (symptom-to-diagnosis time: 10 hours (6.2-62) vs. 4 hours (2.2-23), p=0.004). At diagnosis, older patients had more complications: cardiac tamponade (33% vs 23%, p= 0.352), hemopericardium (69% vs 38%, p= 0.01), shock (45% vs 30%, p=0.180) and renal failure (40% vs 20%, p= 0.132). The surgical risk of older patients was higher (table) and they underwent surgery in a lower proportion (59.3% vs. 87.3%, p= 0.004). Once diagnosed, time to surgery was similar between groups (3.2h (1.6-10) vs. 2.7h (2.1-5.7), p= 0.728). Despite the increased risk, surgery was associated with a mortality reduction in both patient groups (figure). In patients who underwent surgery, the incidence of post-surgical atrial fibrillation was higher in the group of older patients, with no significant differences in the remaining complications (table). Conclusion Elderly patients with AAS-A have more comorbidities, are diagnosed later and have a higher mortality than those with younger age. Despite this, surgery is associated with a mortality reduction even in the older population. Age alone should not be a contraindication for surgical treatment of AAS-A.Mortality in SAA by age and treatment

Aseptic meningitis and Fabry disease.

Fabry disease is caused by enzymatic defects in alpha-galactosidase A that leads to the accumulation of glycosphingolipids throughout the body, resulting in a multisystemic disorder. The most common neurological manifestations are neuropathic pain, autonomic nervous system dysfunction and strokes, but some rarer neurological manifestations exist. Among these, aseptic meningitis is a possible complication. Our objectives were to measure the prevalence of this complication in a cohort of patients with Fabry disease, and to describe its clinical features. We conducted a retrospective review of Fabry disease patients followed at our tertiary referral center between 1995 and September 2023 with at least one episode of meningitis, and performed a systematic review to identify similar published cases. Four patients out of 107 (3.7%) had at least one episode of aseptic meningitis. Our systematic review identified 25 other observations. The median age of these 29 patients was 29.0 years, the median cerebrospinal fluid leukocyte count was 24 cells/mm3 with a predominance of lymphocytes in 64.7% of cases. In 82.8% of the patients, the diagnosis of Fabry disease was unknown before the meningitis. Large artery stenosis was present in 17.2% of patients and 57.1% of patients had a recent stroke concomitant with the meningitis. Several differential diagnoses were evoked, such as multiple sclerosis or central nervous system vasculitis. Our study suggests that Fabry disease should be considered as a cause of aseptic meningitis. The pathophysiological mechanisms underlying meningeal inflammation remain largely unknown but may reflect the dysregulation of pro-inflammatory signaling pathways.

Implementing protocol-based relaparoscopy for severe complications in laparoscopic colorectal surgery.

Although laparoscopy has demonstrated growing applications for either primary colorectal resections or reoperations, no standardized criteria for implementing laparoscopy in revisional surgery have been reported. This study analyzes a single-center series of major complications after laparoscopic colorectal surgery, undergoing laparoscopic (LR), or open reoperations in compliance with a hemodynamics-based institutional management. This study retrospectively analyzes a series of consecutive patients who primarily underwent either laparoscopic left colectomy or low anterior resection in a tertiary referral center between 2016 and 2021. Major complications requiring reoperation (MCR) were managed through an interdisciplinary protocol and submitted to reoperation according to patient hemodynamics and intra-abdominal contamination. A cohort analysis primarily assessed treatment failure rates (i.e., 90-day mortality and need for further surgery), while postoperative morbidity was secondarily examined. Out of 1137 laparoscopic colorectal resections, 497 patients met eligibility criteria, while 45 (9.1%) developed MCRs were managed according to the standardized interdisciplinary protocol. Revisional surgery was performed through either LR (66.7%) or (33.3%). Treatment failure was 13.3% overall, including additional surgery (11.1%) and 90-day mortality (6.6%) after reoperation. In both overall and anastomotic leak-specific MCRs, relaparoscopy resulted in minimized length of hospital stay, postoperative morbidity, and intensity of care. Relaparoscopy for MCR preserves clinical benefits related to minimally invasive colorectal surgery. Further studies should investigate applicative determinants and impediments related to the center volume.
