Paracetamol and adverse cardiovascular outcomes in patients with heart failure

Abstract Background Paracetamol is the most widely used pain killer worldwide, yet its potential influence on cardiovascular events among patients with heart failure (HF) remains unclear. Thus, this study aims to investigate both the short-term and long-term effects of paracetamol use on all-cause mortality and cardiovascular events in HF patients. Methods Using the previously validated territory-wide clinical information registry, paracetamol use was identified among all eligible patients with HF (N = 211,409) from 2000 to 2020. A case-crossover design was used to investigate the associations between short-term use of paracetamols and all-cause mortality and cardiovascular outcomes. Defined daily dose (DDD) was used to evaluate the dose-response relationship. Additionally, the marginal structural design was applied to model paracetamol use as a time-varying exposure and evaluate its long-term effects during the follow-up period. Results Of all eligible subjects, the mean age was 73.2±12.3 years, and 43.6% was male. Over a median follow-up of 10.5 years (interquartile range: 5.7-15.8), 113,258 (53.6%) patients were re-hospitalised for HF, HF-related death occurred in 11,892 (5.6%) patients, incident myocardial infarction (MI) in 28223 (13.3%) patients, incident stroke in 26458 (12.5%) patients, cardiovascular death (CVD) in 72,175 (34.1%) patients and all-cause death in 123,505 (58.4%) patients. Associating HF rehospitalisation to previous paracetamol exposure using the case-crossover design displayed an elevated risk (OR 3.62, 95% CI 3.53-3.71). Associations were similar for MI (OR 5.77, 95% CI 5.50-6.05), stroke (OR 2.37, 95% CI 2.25-2.49), HF-related death (OR 1.86, 95% CI 1.75-1.98), CVD (OR 3.64, 95% CI 3.55-3.73), and all-cause mortality (OR 3.32, 95% CI 3.26-3.39). Moreover, compared with paracetamol users taking the reference dose, users of low, medium and high doses of paracetamol had 16%, 17% and 52% higher risk of HF rehospitalisation. During the long-term follow-up, the average weighted hazard ratio (HR) for HF rehospitalisation in paracetamol users was 2.48 (95% CI 2.46–2.50) as compared with paracetamol non-users after accounting for all-cause mortality as a competing risk. Similarly, the average weighted HR for incident MI or stroke was 2.71 (2.62-2.81) and 3.45 (3.34-3.57), respectively. However, neutral results were shown for HF-related death, CVD and all-cause mortality. Conclusion The use of paracetamol among patients with HF is common. Paracetamol was associated with adverse cardiovascular outcomes both in short-term and long-term follow-up with a dose-response relationship, while its impact on long-term mortality remained neutral. Future randomized controlled trials or experimental studies are warranted to gain a comprehensive understanding of the underlying mechanisms driving such associations between paracetamol and adverse cardiovascular outcomes.

Prognostic role of remnant cholesterol and traditional cardiovascular risk factors in young adults: results of long-term follow-up of a cohort of 30-year-old norwegians

Abstract Background There are limited data on the prevalence and impact of traditional cardiovascular (CV) risk factors among young adults. In addition, more knowledge on novel CV risk factors is needed to explain the residual risk beyond that of the traditional risk factors. Increasing evidence suggest a causal role of remnant cholesterol (RC) in the development of atherosclerotic cardiovascular disease (CVD) and subsequent clinical events. However, the role of RC in young adults is unresolved. Purpose We aimed to evaluate the prevalence of traditional risk factors and the respective sex-differences in young adults, as well as their association with long-term CV events. Further, we hypothesized that higher RC concentrations are associated with impaired CV prognosis. Methods In year 2000, all 30-year-old inhabitants of our city were invited to a cross-sectional study including assessment of health status, anthropometric measurements, and non-fasting blood samples. RC was calculated as total cholesterol minus (LDL-C + HDL-C). Long-term clinical follow-up was performed through linkage with mandatory national registries, 22 years after inclusion. The primary outcome was a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal ischemic stroke, hospitalization for unstable angina and coronary revascularization. Results A total of 5950 individuals were included (56% women). At baseline, men displayed significantly higher systolic and diastolic blood pressure, total cholesterol, LDL-C and triglycerides, as compared with women (Table 1). Also, men had higher levels of RC (Table 1). During a mean follow-up time of 22 years, 108 events (1.8%) occurred. In multivariable Cox regression analysis, non-West-European ancestry (adjusted [a] HR 1.76, 95% confidence interval [CI] 1.03-2.99), diabetes mellitus (aHR 6.39, 95% CI 2.52-16.2), systolic blood pressure (aHR 1.03, 95% CI 1.01-1.04), and LDL-cholesterol (aHR 1.37, 95% CI 1.11-1.68) were associated with an increased risk of CV events during long-term follow-up. Female gender was associated with a reduced risk of CV events (aHR 0.38, 95% CI 0.23-0.64), whereas smoking status did not show any significant association. RC was identified as a significant predictor of CV events (aHR 1.55, 95% CI 1.11-2.18, per 1.0 mmol/L increase). The highest RC quartile (mean RC: 1.1 mmol/L), had the highest event rate (Figure 1, p<0.001 with log-rank test). Conclusion This study uncovers significant sex-differences in modifiable CV risk factors among young adults at the age of 30, which are associated with increased risk for long-term CV events. Interestingly, increasing concentrations of RC at the age of 30 were strongly associated with impaired long-term CV outcome and should be accounted for in early risk prediction.Baseline characteristics.Remnant cholesterol and CVD events.

Risk of malignancy in patients with Reinke's Edema: evaluation of long-term follow-up results.

Reinke's edema is a benign lesion affecting the subepithelial layer of the vocal cords, often associated with moderate or heavy smoking. Smoking is the most significant risk factor for dysplastic laryngeal lesions, laryngeal carcinomas, and Reinke's edema. Thus, Reinke's edema could potentially be a predisposing factor for laryngeal malignancy in the long term. This study aimed to determine the rate of dysplasia and invasive carcinoma development in the larynx during long-term follow-up of histopathologically confirmed Reinke's edema. Between 2010 and 2019, 28 patients diagnosed with Reinke's edema via microlaryngoscopy and histopathological confirmation were included in this study. Their clinical and pathological data were examined to identify the development of laryngeal dysplasia and malignancy during long-term follow-up. Among the 28 patients, 16 (57%) were female and 12 (43%) were male. A history of smoking was present in 24 (85%) patients. No new pathology was found during long-term follow-up in 21 (75%) patients. None of the patients developed dysplasia or malignancy histopathologically. Seven (25%) patients underwent repeated biopsies during follow-up, and minimal dysplasia was detected in 1 (4%) patient. No invasive carcinoma developed in any patient during long-term follow-up. Despite the high rate of smoking among patients with Reinke's edema, no malignancy developed during long-term follow-up, though there was a low incidence of dysplasia. Therefore, close monitoring of these patients is recommended.

Neoadjuvant chemoradiotherapy in combination with deep regional hyperthermia followed by surgery for rectal cancer: asystematic review and meta-analysis.

Combining chemoradiotherapy (CRT) with deep regional hyperthermia (HT) shows promise for enhancing clinical outcomes in selected rectal cancer patients. This study aimed to integrate the evidence and evaluate the efficacy of this combined treatment approach. Asystematic search of the PubMed, Scopus, and Mendeley databases was performed. This review was conducted according to the PRISMA guidelines. The quality of studies was evaluated using the Newcastle-Ottawa scale (NOS). Random-effects meta-analyses (DerSimonian and Laird) were performed. The primary outcome was pathological complete response (pCR), and secondary endpoints were overall survival (OS), disease-free survival (DFS), local recurrence-free survival (LRFS), and toxicity. In total, 12studies were included, mostly of moderate quality. Patients with locally advanced rectal cancer (LARC; n = 760) and locally recurrent rectal cancer (LRRC; n = 22) were eligible. The pooled pCR rate was 19% (95% confidence interval [CI]: 16-22%) among all 782 patients and 19% (95%CI:16-23%) among 760 LARC patients. Due to significant study heterogeneity, survival outcomes were pooled by excluding LRRC patients. The pooled 5‑year OS rate among 433 LARC patients was 87% (95%CI: 83-90%). The pooled 5‑year DFS and LRFS in LARC patients were 75% (95%CI: 70-80%) and 95% (95%CI: 92-97%), respectively. There was alack of consistent reporting of HT treatment parameters and toxicity symptoms among the studies. The collective clinical evidence showed that neoadjuvant CRT combined with HT in rectal cancer patients is feasible, with a19% pCR rate and excellent survival outcomes in long term follow-up.

Characterization of Patients with Poor Clinical Outcome after Adult Spinal Deformity Surgery: A Multivariate Analysis of Mean 8-Year Follow-Up Data.

Background/Objective: Limited data exist regarding the long-term clinical outcomes and related factors after adult spinal deformity (ASD) surgery. This study aims to characterize patients who experienced poor clinical outcomes during long-term follow-up after ASD surgery. Methods: Patients who underwent ASD surgery with ≥5-vertebra fusion including the sacrum and ≥5-year follow-up were included. They were divided into two groups according to the Oswestry Disability Index (ODI) at the last follow-up: group P (poor outcome, ODI > 40) and group NP (non-poor outcome, ODI ≤ 40). Clinical variables, including patient factors, surgical factors, radiographic parameters, and mechanical complications (proximal junctional kyphosis [PJK] and rod fracture), were compared between the groups. Results: A total of 105 patients were evaluated, with a mean follow-up of 100.6 months. The mean age was 66.3 years, and 94 patients (89.5%) were women. There were 52 patients in group P and 53 patients in group NP. Univariate analysis showed that low T-score, postoperative correction relative to age-adjusted pelvic incidence-lumbar lordosis, T1 pelvic angle (TPA) at last follow-up, and PJK development were significant factors for poor clinical outcomes. Multivariate analysis identified PJK as the single independent risk factor (odds ratio [OR] = 3.957 for PJK development relative to no PJK, OR = 21.141 for revision surgery for PJK relative to no PJK). Conclusions: PJK development was the single independent factor affecting poor clinical outcomes in long-term follow-up. Therefore, PJK prevention appears crucial for achieving long-term success after ASD surgery.

Clinical effects of different types of flaps selected according to local conditions in the treatment of diabetic foot defects

BackgroundThe repair of diabetic foot defects (DFD) is a major challenge in clinical practice. The purpose of this study was to investigate the difference in clinical efficacy of different flap techniques in repairing DFD wounds, and to compare the difference in clinical efficacy of anterolateral thigh perforator flap (ALTP) in repairing DFD and non-DFD.MethodsThis study is a retrospective clinical study of different types of flap reconstruction in patients with DFD admitted to our hospital from January 2010 to December 2021. A total of 40 patients with DFD and 43 patients with non-DFD were included in this study. Detailed preoperative basic information, intraoperative details, postoperative complications and long-term follow-up results were collected.ResultThe comorbidities, wound infection and wound duration of DFD group were more serious than those of non-DFD group. In addition, the incidence of complications was higher in DFD group, the wound healing time was longer, the aesthetic evaluation, the functional recovery rate of ankle joint and the sensory recovery effect of flaps were worse.ConclusionIn this study, it is concluded that different flap techniques can obtain better clinical efficacy in repairing DFD wounds. Compared with non-DFD wounds, the postoperative risk of DFD wounds using free ALTP flaps is higher, but the risk can be reduced by reasonable preoperative vascular examination. Free flap can deal with various irregular wounds and provide more options for clinical repair.Level of evidenceIII, Case–control study.

Right subaxillary small incision on low-age and low-weight infants with congenital heart disease.

As a minimally invasive approach to treating congenital heart disease (CHD), the application of the right subaxillary small incision (RSSI) has been developing fast in its indication spectrum. However, RSSI's use is still quite challenging for the surgical treatment of the low-age and low-weight infant patient group. To investigate the safety and efficacy of performing RSSI surgery, treating CHD for infants with low-age and low-weight. Between March 2010 and April 2023, Low-age (≤6 months) and low-weight (≤5 kg) infants with ventricular or atrial septal defect (ASD) as the main diagnosis were retrospectively included in this study. The infants were divided into the RSSI group and the median sternotomy (MS) group. Preoperative conditions, general surgical conditions, perioperative and postoperative outcomes, and long-term follow-up results were compared between the 2 groups. The study included 783 cases. Of these, 434 were operated with MS, and 349 were operated with RSSI. A1:1 matched MS group (282 cases) and RSSI group (282 cases) were obtained after performing propensity score matching (PSM). Analysis of the 2 groups after PSM showed the differences in residual ASD/VSD, peak airway pressure, fraction of inspired oxygen/partial pressure of oxygen (PaO2/FiO2), and partial pressure of carbon dioxide (PaCO2) before return to the intensive care unit (ICU) and extubation were not statistically significant between groups, whereas mechanical ventilation time (P < 0.001), ICU stay (P < 0.001), and hospitalization time (P < 0.001) were lower in RSSI group; and the differences in perioperative complication outcomes were not statistically significant. Long-term outcomes revealed the rate of thoracic deformity was higher in the MS group. Based on the appropriate selection of patients, compared with MS, RSSI surgery for the treatment of low-age (≤6 months) and low-weight (≤5 kg) infants with CHD yields favorable therapeutic results without increasing surgical risks and causes less trauma, which deserves to be further promoted and applied.

Surgical repair of “Swiss Cheese” ventricular septal defects with two-patch and right ventricular apex-exclusion technique: mid-term follow-up results

Background"Swiss Cheese" ventricular septal defects represent a serious congenital heart disease with suboptimal clinical outcomes and a lack of consensus regarding its management. This study presents mid-term follow-up results of surgical repairs for "Swiss Cheese" ventricular septal defects, utilizing the two-patch and right ventricle apex-exclusion technique.MethodsA retrospective review was conducted on 13 patients who underwent surgical repair utilizing the two-patch and right ventricle apex-exclusion technique at our institution between May 2014 and October 2021. The procedure involved the closure of defects in the outflow tract ventricular septal and the apex trabecular ventricular septal regions using two patches, with concurrent exclusion of the right ventricular apex from the right ventricular inflow tract.ResultsMedian follow-up was 4.9 ± 2.1 years (range: 2–9 years). All cases were successful without mortality or major complications. Two years post-surgery, cardiac magnetic resonance revealed median values for left ventricular ejection fraction, right ventricular ejection fraction, left ventricular end-diastolic volume and right ventricular end-diastolic volume of 63.9% ± 1.8% (range: 61–67%), 49.2% ± 2.6% (range: 46–55%), 39.15 ± 2.11 ml (range: 36.2–42.7 ml), 44.55 ± 3.33 ml (range: 38.7–48.6 ml), respectively. No thrombosis occurred. The latest echocardiography results confirmed normal cardiac function in all cases.ConclusionsThe surgical repair of "Swiss Cheese" ventricular septal defects utilizing the two-patch and right ventricle apex-exclusion technique is a viable approach with favorable mid-term outcomes. More cases and long-term follow-up results are needed to validate the feasibility and safety of this technique.

Application of three-dimensional visualization technology in early surgical repair of bile duct injury during laparoscopic cholecystectomy

ObjectiveThis study aimed to explore the application value of three-dimensional (3D) visualization technology in the early surgical repair of bile duct injury during laparoscopic cholecystectomy (LC).MethodsA retrospective analysis was conducted on the clinical data of 15 patients who underwent early surgical repair of bile duct injury during LC with the assistance of 3D visualization technology at the Hepatobiliary Surgery Department of Ningxia Hui Autonomous Region People’s Hospital from January 2019 to December 2022. Postoperative efficacy and long-term follow-up outcomes were summarized.ResultsBefore the repair surgery, 15 cases of bile duct injury during LC were evaluated using 3D visualization technology according to the Strasberg-Bismuth classification: 2 cases of type C, 4 of type E1, 3 of type E2, 3 of type E3, and 3 of type E4. Intraoperative findings were consistent with the 3D visualization reconstruction results, and all patients successfully underwent hepaticojejunostomy using Roux-en-Y anastomosis guided by the 3D visualization navigation. The time interval between LC and bile duct repair surgery ranged from 5 to 28 (14.2 ± 9.7) days. The surgical time was between 120 and 190 (156.40 ± 23.92) min, and estimated blood loss ranged from 80 to 250 (119.66 ± 47.60) mL. The length of hospital stay ranged from 12 to 25 days (median: 16 days). One patient experienced mild bile leakage after the operation, which healed with conservative treatment. All patients were followed up for 12–56 months (median: 34 months) without any loss to follow-up. During the follow-up period, no complications, such as anastomotic stricture or stone formation, were observed.ConclusionThe application of 3D visualization technology for preoperative evaluation and intraoperative navigation can accurately and effectively facilitate early surgical repair of bile duct injury during LC and has clinical value for promotion and application.

Clinical and prognostic significance of neurosonography of lateral ventricles for infants treated with therapeutic hypothermia during the early neonatal period

Background. Currently, therapeutic hypothermia (TH) is the only approved method for treating hypoxic-ischemic encephalopathy (HIE) that helps improve outcomes. However, it also has significant drawbacks, including the necessity for expensive equipment and treatment technologies, poorly understood pathophysiological mechanisms, and, most importantly, not always well-understood long-term results. Numerous scientific studies report the potential benefits of TH, but the actual risk/benefit ratio is still unknown. The results of long-term follow-up of children who underwent TH and did not have serious neuromotor or intellectual disorders are variable. It is believed that the correlation between neonatal neuroimaging and the degree of nervous system impairment remains poorly defined. Chronic brain injuries diagnosed after the neonatal period, such as parenchymal volume loss, appear to be more prognostically significant, which may be reflected by moderate enlargement of the ventricular system of the brain. The method for determining the size of the ventricular system using ultrasound can be accessible for infants of the first year of life who had HIE but do not have direct indications for magne­tic resonance imaging. Therefore, this study aimed to explore the characteristics of the cerebral ventricular system in infants of the first year of life who suffered severe asphyxia at birth, depen­ding on the method of post-resuscitation care (with or without TH). Materials and ­methods. The study examined the results of neurosonographic examinations of 309 infants during their first year of life. Inclusion criteria were gestational age at birth ≥ 36 weeks and birth weight ≥ 2000 g, manifestations of HIE in the early neonatal period without adverse short-term outcomes (at the time of discharge from the neonatal hospital, the children showed no signs of destructive hypoxic-ischemic lesions of the central nervous system (CNS), seizures, or pathological muscle tone, and had full oral feeding). Exclusion criteria were diagnosed congenital CNS abnormalities, neuroinfections, psychomotor development delay of more than 3 months during the first years of life, progressive obstructive ventriculomegaly or ventriculomegaly associated with non-atrophic subarachnomegaly. The children were divided into three groups: hypothermia group — 19 infants who underwent TH after birth; normothermia group — 14 children who conditio­nally had indications for TH but did not undergo it; comparison group — 276 children in their first year of life who did not require TH (Apgar score &gt; 5 at 10 minutes of life, manifestations of mild or moderate HIE (according to the Sarnat scale) during the first days of life). Neurosonographic examinations were conducted at the age of 2–7 months (mean of 2.12 ± 0.07 months). The sizes of the lateral ventricles were assessed in comparison with the results from the control group of infants of the same age (34 healthy children with no recorded factors of complicated perinatal period, no signs of neurological dysfunction during the neonatal period, and the seven-month observation). Enlargement of the lateral ventricles was recorded when the size of the anterior horn or body of the ventricle in the parasagittal projection exceeded the 95th percentile of the corresponding measurements from the control group. Results. Enlargement of the lateral ventricles during the neurosonographic examination was detected in 36.8 % of children in the hypothermia group, 14.3 % in the normothermia group, and 8.0 % of children in the comparison group. Significant differences were registered only when comparing the results of the hypothermia group with the comparison group (p &lt; 0.05, Fisher’s exact test). Significant correlations (p &lt; 0.05) were found between the size of the lateral ventricles and clinical signs such as sleep disturbances, decreased muscle tone in the arms, increased tendon reflexes, delayed motor development, increased muscle tone in a pyramidal pattern, and diffuse muscle hypotonia. Conclusions. Thus, infants who had severe asphyxia at birth and underwent TH significantly more often had enlargement of the cerebral ventri­cular system (versus the comparison group). Therefore, although therapeutic hypothermia improves outcomes for the development of the nervous system in children who have moderate and severe hypoxic-ischemic encephalopathy, brain morphology (particularly the state of the ventricular system) may still be altered in infants during the first year of life. And the presence of significant correlations between the size of the lateral ventricles and clinical signs of neurological dysfunction argues for further clinical monitoring of children after therapeutic hypothermia throughout the first years of life and in the absence of short-term adverse outcomes of HIE or significant delays in psychomotor development during the first year of life.

Diverse Clinical and Immunological Profiles in Patients with IPEX Syndrome: a Multicenter Analysis from Turkey.

Immunodysregulation, Polyendocrinopathy, Enteropathy, and X-linked syndrome (IPEX), caused by pathogenic FOXP3 variants, is a rare autoimmune disorder with diverse clinical features, including early-onset diabetes, eczema, and enteropathy. Atypical cases show milder symptoms and unique signs, requiring different treatments. Therefore, there are ambiguities in the accurate diagnosis and management of IPEX. We sought to present clinical, genetic, and immunological assessments of 12 IPEX patients with long-term follow-up to facilitate the diagnosis and management of the disease. Clinical findings and treatment options of the patients were collected over time. Lymphocyte subpopulations, protein expressions, regulatory T (Treg) and circulating T follicular helper (cTFH) cells, and T-cell proliferation were analyzed. Predominant presentations included autoimmunity (91.6%), failure to thrive (66.7%), and eczema (58.3%). There were four classical and eight atypical IPEX individuals. Allergic manifestations were more common in atypical patients. Notably, chronic diarrhea demonstrated heightened severity compared to other manifestations. Four patients (33.3%) demonstrated eosinophilia, and nine (75%) showed high serum IgE levels. Most patients exhibited normal percentages of Treg cells with reduced CD25, FOXP3, and CTLA-4 expressions, corrected after hematopoietic stem cell transplantation (HSCT). Compared to healthy controls, the TH2-like skewing accompanied by reduced TH17-like responses was observed in cTFH and Treg cells of patients. Overall, nine patients (75%) received immunosuppressants (ISs), and six (50%) underwent HSCT, which was the only treatment revealing sustained control. Sirolimus was used in six patients and showed better control than other ISs. The first cohort from Turkey with long-term follow-up results, comparing typical and atypical cases, provides insights into the outcomes of different therapeutic modalities and T- cell subtype changes in IPEX syndrome.

Long-Term Outcome of Patients with Low-Risk Differentiated Thyroid Cancer Treated with Total Thyroidectomy Alone.

Differentiated thyroid carcinoma (DTC), mainly papillary (PTC), at low risk of recurrence is currently managed with active surveillance strategies or less aggressive surgeries. However, total thyroidectomy with 131I treatment is still performed both if these tumors are diagnosed before or occasionally after surgery. This real-life study aimed to evaluate the rate of biochemical, structural, and functional events in a large series of consecutive DTCs at low risk of recurrence treated by total thyroidectomy, but not with 131I, in a medium-long-term follow-up. We evaluated clinical-pathologic data of 383 consecutive patients (2006-2012) with unifocal DTC [T1a/b(s)] at low risk of recurrence, treated with total thyroidectomy but without lymph node dissection and 131I treatment after surgery. We evaluated if structural, biochemical, and functional events were detected during the follow-up. Females accounted for 75.7% of our study group, and the median age was 50 years. The median tumor dimension was 0.4 cm (range 0.1-1.2). Most of the patients had a unifocal T1a tumor (98.9%), and 73.6% had a classic variant of PTC. We divided the patients according to the absence (group A-n = 276) or presence (group B-n = 107) of interfering TgAb at first control after surgery. After a median follow-up of 10 years, no structural events were detected. Sixteen out of three hundred and eighty-three (4.2%) patients developed biochemical events: 12/276 (4.3%) in group A and 4/107 (3.7%) in group B. The median time elapsed from surgery to detecting a biochemical event was 14.5 and 77.5 months in groups A and B, respectively. No patients performed additional treatments and were followed up with an active surveillance strategy. This study confirmed that patients with DTC at low risk of recurrence showed an excellent outcome in a medium long-term follow-up since no structural events were diagnosed. Significant variations in Tg/TgAb were detected in a few cases, all managed with an active surveillance strategy without the need for other treatments. Therefore, a relaxed follow-up with neck ultrasound and Tg/TgAb measurement is enough to early identify those very unusual cases of recurrence.

Selection strategy for endoscopic necrosectomy approaches of infected walled-off pancreatic necrosis: Analysis of 101 patients from a single center with long-term follow-up.

Endoscopic necrosectomy (EN) is a promising minimally invasive approach for treating infected walled-off pancreatic necrosis (WOPN). Multiple EN approaches are currently available, though criteria for selecting the optimal approaches are lacking. We aimed to propose a rational selection strategy of EN and to retrospectively evaluate its safety and effectiveness. Altogether 101 patients who underwent EN for infected WOPN at a tertiary hospital between June 2009 and February 2023 were retrospectively included for analysis. Demographic characteristics, details of the EN procedures, procedure-related adverse events, and clinical outcomes were investigated. Among these 101 patients with WOPN, 56 (55.4%) underwent transluminal EN, 38 (37.6%) underwent percutaneous EN, and seven (6.9%) underwent combined approach, respectively. Clinical success was achieved in 94 (93.1%) patients. Seven (6.9%) experienced procedure-related adverse events, and seven (6.9%) died during the treatment period. During a median follow-up of 50 months, 5 (5.3%) of the 94 patients had disease recurrence, 17.0% (16/94) had new-onset diabetes mellitus, and 6.4% (6/94) needed oral pancreatic enzyme supplementation. The clinical success rate, procedure-related adverse event rate, and long-term follow-up outcomes were not significantly different among the three groups. High APACHE-II scores (≥15) and organ failure were identified as factors related to treatment failure. A selection strategy for EN approaches, based on the extent of necrosis and its distance from the gastrointestinal lumen (using a threshold of 15 mm), is safe and effective for treating infected WOPN in both short-term and long-term outcomes.

Special-form radial collateral artery perforator flaps for the reconstruction of complex hand defects

BackgroundThe reconstruction of complex wounds of the hand still has challenges in achieving aesthetic, functional and sensory recovery. We presented our experience of using the polyfoliate and chimeric radial collateral artery perforator flaps (RCAPF) to repair complex hand defects, aiming to explore the feasibility of special-form RCAPFs in hand coverage and enhance the comprehension of their respective indications.MethodsFrom June 2014 to March 2021, 26 cases (19 males and 7 females, mean 44.4 years) underwent defect and sensation reconstruction of their hands with special-form RCAPFs, which manifested as multiple adjacent or irregular single wounds and composite tissue defects complicated with a degree of nerve injury. The clinical effects of the free RCAPFs were evaluated by integrating the postoperative and long-term follow-up outcomes of all cases.ResultsAltogether 8 polyfoliate flaps, 17 chimeric flaps and 1 polyfoliate-chimeric flap were harvested. Of them, 23 flaps survived uneventfully in one stage. Venous congestion occurred in 3 cases, two of which survived through vascular exploration and another one was finally repaired by the contralateral RCAPF. The follow-up results showed that the appearance of both the recipient and donor sites mostly recovered satisfactory. All the bone flaps properly healed. The BMRC sensory evaluation results of all skin flaps were S4 in 8 flaps, S3 in 18 flaps, and S2 in 9 flaps.ConclusionsThe free RCAPFs can be designed in various forms with a reliable blood supply, contributing to reconstructing simple and multiple wounds of the hand with or without bone defects and dead space.

Long-term follow-up results and visual outcomes of childhood glaucoma in the black sea region of turkey.

To investigate long-term visual outcomes and factors associated with low vision in patients with childhood glaucoma. A retrospective review was conducted on the medical records of pediatric glaucoma patients at the Ondokuz Mayıs University Ophthalmology Clinic from 2005 to 2023. The patients were categorized into three groups: primary congenital glaucoma (PCG), secondary childhood glaucoma, and glaucoma following cataract surgery (GFCS). Groups were analyzed regarding visual acuity (VA), ocular conditions and comorbidities, and the cause of visual impairment. The study also investigated the potential risk factors associated with visual impairment. A total of 105 eyes of 60 patients with a mean age of 9.7 ± 5.5years were included in the study. The mean VA in logMAR was 0.59 ± 0.52. At the final follow-up, 34.1% had good VA (≥ 20/50), 29.5% had moderate VA (20/50-20/200), and 36.4% had poor VA (< 20/200). The final mean intraocular pressure (IOP) was 16.2 ± 6.2mmHg. Amblyopia was the leading cause of vision loss (38.2%), followed by glaucomatous damage (36.4%). Patients with GFCS had a higher rate of visual impairment (42.4%) and refractive error. The results of the regression analysis showed that low vision was associated with undergoing more than two surgeries, high IOP at baseline, high initial and final cup-to-disc (C/D) ratio, and high initial central corneal thickness (CCT) (CI 95%, p = 0.018, p= 0.017, p = 0.013, p = 0.003, p = 0.001, respectively). Good VA can be achieved in 34.1% of childhood glaucoma cases. However, the VA prognosis may be worse in patients with GFCS. Achieving good visual outcomes in childhood glaucoma requires timely and effective treatment, consideration of risk factors, and management of amblyopia and ocular comorbidities.

Long-term follow-up of pilonidal sinus disease treated by radial laser surgery

PurposeLaser ablation is one of the newest and most advanced minimally invasive techniques in treating pilonidal sinus disease (PSD). Most studies on the subject have small sample sizes and relatively short follow-up times, making evaluation of long-term healing rates and recurrences difficult. Furthermore, long-term results for laser surgery of PSD are still lacking. The aim of this study was to retrospectively report long-term follow-up results for PSD treatment by radial laser surgery.MethodsWe retrospectively studied the medical records of 83 patients who underwent the radial laser procedure for PSD between January 2017 and September 2019. Our follow-up time was a median of 5.2 years, range 1.5 to 7.4 years.ResultsTwelve patients had a PSD recurrence after their laser procedure, which gives a recurrence rate of 14.5% (95% CI 8.2%-23.2%). These recurrences appeared at a median 12.2 months after the laser procedure, range 4.2 to 51 months. A total of 23 patients (27.7%; 95% CI 19.0–38.0) underwent a reoperation, 11 patients due to postoperative infection or prolonged recovery and 12 patients due to PSD recurrence. Recurrent PSD and spillage of pus during operation were statistically significantly associated with the need for a second operation.ConclusionRadial laser surgery provides a minimally invasive treatment option with an acceptable recurrence rate in long-term follow-up.

RECONSTRUCTION OF PAPROSKY TYPE III ACETABULAR BONE DEFECTS IN REVISION HIP ARTHROPLASTY USING A COMBINATION OF CAGE AND MORSELIZED ALLOGRAFTS

The management of severe acetabular bone defects poses a complex challenge in revision hip arthroplasty. Although biological fixation materials are currently dominant, cage has played an important role in complex acetabular revision in the past decades, especially when a biological prosthesis is not available. The purpose of this study is to report the long-term clinical and radiographic results of Paprosky type Ⅲ acetabular bone defects revised with cage and morselized allografts.We retrospectively analyzed 45 patients who underwent revision hip arthroplasty with cage and morselized allografts between January 2007 and January 2019. Forty-three patients were followed up. There were 19 Paprosky type IIIA bone defect patients and 24 Paprosky type IIIB bone defect patients and 7 patients of the 24 were also with pelvic discontinuity. Clinical assessment included Harris Hip Score (HHS) and Short Form-12 (SF-12). Radiographic assessment included cage stability, allografts incorporation, and center of rotation.All patients were followed up with a mean follow-up of 10.6 years, HHS and SF-12 improved significantly at last follow-up in comparison to the preoperative. There were 2 re-revisions, one at 5 years after surgery, another at 13.6 years after surgery. Two patients had nonprogressive radiolucency in zone III and the junction of zone II and zone III at the bone implant interface. Allografts of 40 (93%) cases incorporated fully.The combination of cage and morselized allograft is an alternative option for acetabular revision with Paprosky type III bone defects with satisfactory long-term follow-up results.

Long-Term Follow-up Results of Children with Urolithiasis Followed in Our Clinic

Title and Objective: Urolithiasis is a prevalent condition frequently observed in childhood within the Turkish population. The aim of this study was to evaluate the metabolic, radiological, and clinical features of pediatric patients with urolithiasis. Materials and Methods: Records of 158 children referred to the Pediatric Nephrology Department of Celal Bayar University between 2010 and 2020 with suspected urolithiasis and microlithiasis were retrospectively reviewed. The complaints and ages of the cases during hospital admission, their medical histories, and the location of the stones were determined. All patients underwent complete urine analysis, spot urine electrolytes, urine culture, serum electrolytes, kidney function tests, uric acid, albumin measurements, and urinary ultrasonography. 24-hour urine electrolytes were studied in patients capable of urine collection. Stone analysis using X-ray diffraction was performed on patients from whom stones were obtained. Results: Out of the individuals, 88 (55.7%) were male, and 70 (44.3%) were female, resulting in a male-to-female ratio of 1.25:1. The average age at the time of diagnosis was determined to be 89.82 ± 57.35 months. A family history of urolithiasis was reported in 108 (68.3%) patients, and 46 individuals (29%) were born from consanguineous marriages. At the time of diagnosis, 32 patients (20%) had a urinary tract infection. Stones were predominantly situated in the upper urinary system in 129 patients (81.6%), with 123 (77.8%) having unilateral stones and 35 (22.2%) having bilateral stones. Calcium oxalate stones were the most commonly observed (80%) in patients who underwent stone analysis. Hypercalciuria emerged as the most frequently identified urinary metabolic risk factor. At the end of the follow-up period, 14 patients experienced a recurrence, while 67 patients remained free of stones. Conclusion: Urolithiasis continues to be a significant concern among children in our nation. Due to the higher recurrence rate and more frequent underlying metabolic disorders in children with stone diseases compared to adults, metabolic assessment and stone analysis are recommended procedures, emphasizing the need for lifelong monitoring in these cases.
