Retrospective Single-center Experience Research Articles

Analysis of interventional treatment options of the common femoral artery - a retrospective single center experience.

Background: Due to the rapid development of treatment techniques of peripheral arterial disease (PAD) treatment is nowadays predominantly interventional. An exception are lesions of the common femoral artery (CFA), which should be treated surgically according to vascular guidelines. However, recent evidence has shown that endovascular techniques, e.g. stenting, have comparable clinical outcomes while causing fewer complications. The aim of the present analysis was to evaluate the therapeutic success of endovascular therapy of CFA lesions in a single center, all - comers registry. Patients and methods: All patients who were treated for a CFA lesion at the Department of Internal Medicine I of the University Hospital Jena in the period from 01/2017 to 12/2020 were included. Treatment success was determined by evaluating the ankle-brachial-index (ABI) pre- and post-interventional as well as after follow-up (FU), measuring walking distance (WD) and by target revascularization rate (TLR) and primary patency rate (PPR). Results: The analysis included 109 patients with a mean age of 73.4 years, with 67% (73) of those being men. 72 patients received interventional treatment, whereas 33 were treated surgically and 4 conservatively. Resting ABI in the overall cohort showed an increase from 0.5 to 0.7 post intervention (p=<0.05; mean FU-time: 6.5 months). In the interventional cohort ABI increases from 0.6 to 0.8 (p=<0.05; mean FU-time: 5,8 months) at FU and from 0.3 to 0.6 (p=<0.05; mean FU-time: 8,8 month) in the surgically treated group. The WD improved in the whole collective from 116.5 meter (m) to 152.5 m (p=<0.05). The TLR showed no significant difference with 8.1% after interventional treatment and 6.1% after vascular surgery in the present analysis (p=0.72) as well as PPR with 89.8% after EVT and 90.9% after surgical approach (p=0.87). The intra-/postinterventional complication rate was 5.5% in the intervention group, compared to postoperative complication rate of 15.2% in the surgically treated group. Conclusions: The present analysis demonstrates that even in a real-world, all-comers collective, interventional therapy for CFA lesions was safe and equally effective as the surgically treated patient cohort. Continuing to generate registry data is important to eventually initiate a paradigm shift.

Clinical characteristics of pyogenic liver abscess with and without biliary surgery history: a retrospective single-center experience

Background & aimsPyogenic liver abscess (PLA) is a common hepatobiliary infection that has been shown to have an increasing incidence, with biliary surgery being identified as a trigger. Our aim was to investigate the clinical characteristics and treatments of PLA patients with and without a history of biliary surgery (BS).MethodsThe study included a total of 353 patients with PLA who received treatment at our hospital between January 2014 and February 2023. These patients were categorized into two groups: the BS group (n = 91) and the non-BS group (n = 262). In the BS group, according to the anastomosis method, they were further divided into bilioenteric anastomoses group (BEA, n = 22) and non-bilioenteric anastomoses group (non-BEA, n = 69). Clinical characteristics were recorded and analyzed.ResultsThe percentage of PLA patients with BS history was 25.78%. The BS group exhibited elevated levels of TBIL and activated APTT abnormalities (P = 0.009 and P = 0.041, respectively). Within the BS group, the BEA subgroup had a higher prevalence of diabetes mellitus (P < 0.001) and solitary abscesses (P = 0.008) compared to the non-BEA subgroup. Escherichia coli was more frequently detected in the BS group, as evidenced by positive pus cultures (P = 0.021). The BS group exhibited reduced treatment efficacy compared to those non-BS history (P = 0.020). Intriguingly, the BS group received a higher proportion of conservative treatment (45.05% vs. 21.76%), along with reduced utilization of surgical drainage (6.59% vs. 16.41%).ConclusionsPatients with BS history, especially those who have undergone BEA, have an increased susceptibility to PLA formation without affecting prognosis.

Factors affecting graft healing in laryngotracheal reconstruction: a retrospective single-center experience.

To examine the factors that affect graft healing after laryngotracheal reconstruction (LTR). We conducted a retrospective chart review at King Abdulaziz University Hospital, Riyadh, Saudi Arabia, between January-2008 and October-2023. We included all patients who underwent LTR and required anterior and/or posterior graft placement, while those who underwent procedures without graft placement and those with incomplete information were excluded. Forty-nine patients were analyzed. Most patients were pediatric (65.3%), male (65.3%), had no coexisting comorbidities (55.1%), and harbored grade 3-4 stenosis (59.2%). Thirty patients (61.2%) underwent open surgery. Various graft complications occurred including infection (n = 1, 2%), dehiscence (n = 3, 6.1%), scar (n = 6, 12.2%), and granulation (n = 29, 59.2%). Only 15 patients (30.65%) achieved the composite status of "healthy" graft. Among 43 patients who had postoperative cultures, positive results for Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus were observed in 10 and four patients, respectively. Open surgery and double-stage procedure were significantly associated with higher rates of granulation tissue formation. Pediatric-age group had significantly higher rate of complete epithelization compared to adult-age group. A significantly greater proportion of patients who had unhealthy grafts had open surgery. The rate of double-stage LTR was significantly higher in unhealthy grafts compared to healthy grafts. Prolonged stent duration was linked to various graft-related complications. Multivariate logistic regression analyses showed no statistically significant correlations between various factors and postoperative graft-related complications. Open surgery, double-stage procedure, pediatric age group, and stent duration were not significant risk factors associated with postoperative graft-related complications during LTR in multivariate analysis.

Comparison of Glidesheath Slender and Subcutaneous Nitrate Administration in Terms of Radial Artery Complications: A Retrospective Single-Center Experience.

The transradial route is used in most coronary procedures today. Although this method seems to be advantageous in terms of bleeding complications and patient comfort, the small radial artery diameter brings with it complications such as radial artery spasm and occlusion. It has been demonstrated in previous studies that subcutaneous nitrate administration dilates the radial artery. The Glidesheath Slender, which has a thinner outer wall than conventional sheaths, is another method that has been shown to reduce complications by reducing friction on the radial artery wall. Our aim was to compare these two methods in terms of complications. We retrospectively reviewed patients with complete clinical and radial Doppler ultrasound records who had undergone transradial interventions. We compared procedures using subcutaneous nitrate application plus conventional sheaths with procedures using the Glidesheath Slender sheath in terms of procedural and post-procedural complications. Eighty-seven patients in the subcutaneous nitrate group and 35 patients in the Glidesheath Slender group were included in the study. There were no significant differences between the two groups in terms of procedural and postprocedural complications (p = 0.511 and p = 0.333, respectively). In cases where a thin-walled sheath such as a Glidesheath Slender is not available, subcutaneous nitrate administration seems to be similar, especially in terms of preventing radial artery spasm.

Contrast-Enhanced Mammography-Guided Biopsy: Preliminary Results of a Single-Center Retrospective Experience.

Background: CEM-guided breast biopsy is an advanced diagnostic procedure that takes advantage of the ability of CEM to enhance suspicious breast lesions. The aim pf this paper is to describe a single-center retrospective experience on CEM-guided breast biopsy in terms of procedural features and histological outcomes. Methods: 69 patients underwent the procedure. Patient age, breast density, presentation, dimensions, and lesion target enhancement were recorded. All the biopsy procedures were performed using a 7- or 10-gauge (G) vacuum-assisted biopsy needle. The procedural approach (horizontal or vertical) and the decubitus of the patient (lateral or in a sitting position) were noted. Results: A total of 69 patients underwent a CEM-guided biopsy. Suspicious lesions presented as mass enhancement in 35% of cases and non-mass enhancement in 65% of cases. The median size of the target lesions was 20 mm. The median procedural time for each biopsy was 10 ± 4 min. The patients were placed in a lateral decubitus position in 52% of cases and seated in 48% of cases. The most common approach was horizontal (57%). The mean AGD was 14.8 mGy. At histology, cancer detection rate was 28% (20/71). Conclusions: CEM-guided biopsy was feasible, with high procedure success rates and high tolerance by the patients.

Intraplaque injections of hyaluronic acid for the treatment of stable-phase Peyronie's disease: a retrospective single-center experience.

Peyronie's disease (PD) is a condition of penile connective tissue affecting up to 10% of men worldwide. In the complexity of its management, nonsurgical treatments, such as intraplaque injections, are gaining attention. The current literature shows data on the efficacy of intraplaque injections of hyaluronic acid (HA) mainly in acute-phase PD. However, data on injections of HA in stable-phase PD are lacking. Data for this retrospective study were derived from a prospectively maintained database of private patients presenting at a private medical practice affiliated to the University of Naples "Federico II" (Naples, Italy) with stable-phase PD between January 2020 and March 2023. Patients underwent a standard protocol of three injections, each administered at a two-week interval. During the intervals, patients performed vacuum device therapy, penile stretching, and modeling exercises. All patients compiled the Peyronie's Disease Questionnaire (PDQ) and Global Assessment of Peyronie's Disease (GAPD) at baseline and 2 weeks after the third injection. A penile Doppler ultrasound was performed 2 weeks after the last injection to record the final curvature. Overall, we recruited 62 patients with stable-phase PD and a mean (±standard deviation [s.d.]) curvature of 52.7° (±9.7°). After 6 weeks, eight (12.9%) patients did not experience any curvature improvement. The remaining 54 patients had a final mean (±s.d.) curvature of 40.3° (±9.1°) with P < 0.001, compared to that before treatment. We found improvement in all PDQ domains (all P ≤ 0.01), and 50 (80.6%) patients reported subjective improvement of the penile curvature according to the GAPD. In conclusion, we demonstrated that after three injections of HA administered according to the adopted protocol, patients with stable-phase PD could experience significant improvements in penile curvature, and physical and psychological consequences of the disease without significantly relevant side effects.

Local treatment in initially unresected non-rhabdomyosarcoma soft-tissue sarcomas of children and adolescents: A retrospective single-center experience.

Pediatric non-rhabdomyosarcoma soft-tissue sarcomas (NRSTS) are a heterogeneous group of aggressive tumors. Patients with locally advanced/initially unresected disease represent a subset of patients with unsatisfactory outcome: limited data are available on the best treatment approach, in particular regarding local therapy. This retrospective analysis concerned 71 patients<21 years old with nonmetastatic, initially unresected adult-type NRSTS, treated at a referral center for pediatric sarcomas from 1990 to 2021. Patients were treated using a multimodal approach, based on the protocols adopted at the time of their diagnosis. The series included a selected group of patients with unfavorable clinical characteristics, i.e., most cases had high-grade and large tumors, arising from axial sites in 61% of cases. All patients received neoadjuvant chemotherapy, 58 (82%) had delayed surgery (R0 in 45 cases), and 50 (70%) had radiotherapy. Partial response to chemotherapy was observed in 46% of cases. With a median follow-up of 152 months (range, 18-233), 5-year event-free survival (EFS) and overall survival (OS) were 39.9% and 56.5%, respectively. Survival was significantly better for patients who responded to chemotherapy, and those who had a delayed R0 resection. Local relapse at 5 years was 7.7% for patients who did not undergo delayed surgery. Our series underscores the unsatisfactory outcome of initially unresected NRSTS patients. Improving the outcome of this patient category requires therapeutic strategies able to combine novel effective systemic therapies with a better-defined local treatment approach to offer patients the best chances to have R0 surgery.

Management of groin hernias in emergency setting: differences in indications and outcomes between laparoscopic and open approach. A single-center retrospective experience

PurposeThe use of minimally invasive groin hernia repair techniques in an emergency setting is still debated and its widespread is limited.The aim of this study is to evaluate the safety and efficacy of the laparoscopic transabdominal preperitoneal (TAPP) technique in the treatment of inguinal and femoral hernias in emergency setting based on our experience, comparing indications and outcomes with the open technique.MethodsA retrospective analysis was performed including all patients with incarcerated and/or strangulated groin hernia who underwent emergency surgery from November 2019 to September 2022.Perioperative variables and short- and long-term outcomes were examined.Statistical analysis was performed using chi-square test for nominal variables and Student’s t test for continuous ones. A p value < 0.05 was considered statistically significant.ResultsSixty-six patients were included: 29 patients were treated with TAPP technique (Tapp group) and 37 with open technique plus diagnostic laparoscopy (Open group). Patients in the TAPP group were younger, had less severe clinical scenarios, and had a trend for lower Charlson Comorbidity Index, whereas ASA score and BMI were similar. The small bowel was more frequently herniated in the open group.Bilateral hernia repair was performed in 20.69% of patients in the Tapp group versus 0% in the Open group (p = 0.004). Bowel resection was more frequent in the open group (48.65% vs 0% of the Tapp group, p < 0.001) length of surgery was comparable in the two groups. In the Tapp group, the length of hospitalization was significantly shorter (2.59 ± 2.28 days vs. 9.08 ± 14.48 days; p = 0.023).Postoperative complications, according to Clavien-Dindo, were more severe in Open group where there were two deaths. There were no differences in the number of readmission and re-operations at 30 days and in the recurrence rate.ConclusionsEmergency repair of inguinal and femoral hernias using TAPP is a valuable option, safe and feasible in selected patients. In this series, indications for TAPP were reserved to younger patients with less comorbidities and less severe clinical scenario. Future randomized studies are needed to compare TAPP with open emergency hernia surgery in all settings. Potential advantages of TAPP are the reduction of postoperative complications, earlier recovery, and the possibility of bilateral treatment.

Cornual Pregnancy: Results of a Single-Center Retrospective Experience and Systematic Review on Reproductive Outcomes.

Background and Objectives: Cornual pregnancies (CPs) are rare forms of ectopic pregnancy. When abortion does not occur, it can be a life-threatening condition for the mother and can also impair future fertility. We present our experience in the diagnosis and management of CPs. A systematic review was also conducted to investigate the reproductive outcomes after treatment. Materials and Methods: Between January 2010 and December 2022, we performed a retrospective, cross-sectional, single-center, and descriptive data collection and analysis (ClinicalTrial ID: NCT06165770). The search for suitable articles published in English was carried out using the following databases (PROSPERO ID: CRD42023484909): MEDLINE, EMBASE, Global Health, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Cochrane Methodology Register), Health Technology Assessment Database, Web of Science, and search register such as ClinicalTrial. Only studies describing the impact of CP treatment on fertility were selected. Results: Two studies were included in the systematic review. Seventeen patients suffering from CPs were selected. In our series, a pelvic ultrasound allowed for the diagnosis of a cornual localization in 35.30% of cases. Thirteen women (76.47%) underwent immediate surgical management. The laparoscopic approach was the most used (76.92%), with a laparotomic conversion rate of 30%. Four patients (23.52%) received medical treatment with methotrexate. After treatment, two patients managed to achieve pregnancy. Conclusions: CP is a rare form of ectopic pregnancy that can quickly become life-threatening for the mother. Ultrasound does not lead to a precise diagnosis in all cases. In the absence of complications and emergencies, laparoscopy is an approach that could be considered valid. For selected asymptomatic patients, medical treatment may be a valid alternative. The data from the studies included in the systematic review, although demonstrating a superiority of medical treatment in terms of future pregnancies, are heterogeneous and do not allow us to reach a definitive conclusion.

High-Risk Neutropenic Fever and Invasive Fungal Diseases in Patients with Hematological Malignancies.

Invasive fungal diseases (IFDs) still represent a relevant cause of mortality in patients affected by hematological malignancies, especially acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) undergoing remission induction chemotherapy, and in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. Mold-active antifungal prophylaxis (MAP) has been established as a standard of care. However, breakthrough IFDs (b-IFDs) have emerged as a significant issue, particularly invasive aspergillosis and non-Aspergillus invasive mold diseases. Here, we perform a narrative review, discussing the major advances of the last decade on prophylaxis, the diagnosis of and the treatment of IFDs in patients with high-risk neutropenic fever undergoing remission induction chemotherapy for AML/MDS and allo-HSCT. Then, we present our single-center retrospective experience on b-IFDs in 184 AML/MDS patients undergoing high-dose chemotherapy while receiving posaconazole (n = 153 induction treatments, n = 126 consolidation treatments, n = 60 salvage treatments). Six cases of probable/proven b-IFDs were recorded in six patients, with an overall incidence rate of 1.7% (6/339), which is in line with the literature focused on MAP with azoles. The incidence rates (IRs) of b-IFDs (95% confidence interval (95% CI), per 100 person years follow-up (PYFU)) were 5.04 (0.47, 14.45) in induction (n = 2), 3.25 (0.0013, 12.76) in consolidation (n = 1) and 18.38 (3.46, 45.06) in salvage chemotherapy (n = 3). Finally, we highlight the current challenges in the field of b-IFDs; these include the improvement of diagnoses, the expanding treatment landscape of AML with molecular targeted drugs (and related drug-drug interactions with azoles), evolving transplantation techniques (and their related impacts on IFDs' risk stratification), and new antifungals and their features (rezafungin and olorofim).

Refractory circulatory failure in COVID-19 patients treated with veno-arterial ECMO a retrospective single-center experience.

In this retrospective case series, survival rates in different indications for veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and differential diagnoses of COVID-19 associated refractory circulatory failure are investigated. Retrospective analysis of 28 consecutive COVID-19 patients requiring VA-ECMO. All VA-ECMO's were cannulated peripherally, using a femoro-femoral cannulation. At VA-ECMO initiation, median age was 57 years (IQR: 51-62), SOFA score 16 (IQR: 13-17) and norepinephrine dosing 0.53μg/kg/min (IQR: 0.35-0.87). Virus-variants were: 61% wild-type, 14% Alpha, 18% Delta and 7% Omicron. Indications for VA-ECMO support were pulmonary embolism (PE) (n = 5, survival 80%), right heart failure due to secondary pulmonary hypertension (n = 5, survival 20%), cardiac arrest (n = 4, survival 25%), acute heart failure (AHF) (n = 10, survival 40%) and refractory vasoplegia (n = 4, survival 0%). Among the patients with AHF, 4 patients suffered from COVID-19 associated heart failure (CovHF) (survival 100%) and 6 patients from sepsis associated heart failure (SHF) (survival 0%). Main Complications were acute kidney injury (AKI) 93%, renal replacement therapy was needed in 79%, intracranial hemorrhage occurred in 18%. Overall survival to hospital discharge was 39%. Survival on VA-ECMO in COVID-19 depends on VA-ECMO indication, which should be considered in further studies and clinical decision making. A subgroup of patients suffers from acute heart failure due to inflammation, which has to be differentiated into septic or COVID-19 associated. Novel biomarkers are required to ensure reliable differentiation between these entities; a candidate might be soluble interleukin 2 receptor.

Assessment of Incidence of Distress and Utilization of Supportive Care Services in Multiple Myeloma Patients, a Retrospective Single Center Experience

Introduction: Multiple myeloma (MM) is the second most common hematological malignancy. Current literature represents substantial underutilization of guideline-recommended supportive services (SS) in MM patients. Earlier studies have shown that most patients with MM have focal osseous lesions leading to skeletal-related events, fractures, pain, and debility. These events may negatively affect the treatment course and result in poor quality of life. Recent NCCN and ASCO guidelines recommend utilization of SS in all patients by early integration of cancer care for symptom control while being treated for primary malignancy. We evaluated the level of distress in patients (pts), SS utilization, ED visits, and hospitalization in pts with MM. Methods: We included adult patients (≥18 years) with newly diagnosed or relapsed/refractory MM at Levine Cancer Institute who had completed an electronic distress survey (EDS) within three months of diagnosis or relapse. Amyloidosis and plasma cell leukemia diagnoses were excluded. The EDS includes questions related to sociodemographic, patient-reported outcomes (PROs): distress level, physical symptoms (scale 0 - 10), screening for depression (PHQ-2, scale 0 - 6), anxiety (GAD-2, scale 0 - 6),Utilization of at least one SS (social work, palliative medicine, psych-oncology, cancer rehab, integrative medicine, and nutrition) within 6 months of EDS and emergency department visits/hospitalizations within 1 year of EDS were collected, retrospectively, from the electronic medical record. The PROs were summarized overall and compared among three distress groups [Distress score (DS) &amp;lt;4, 4-6, ≥7] with Wilcoxon rank sum tests for the EDS symptom scores and Fisher's exact tests for other categorical endpoints. Results: 541 MM pts were identified with an EDS within 3 months of diagnosis or relapse (assessment date range: January 2017 - May 2022), with 71.5% of those occurring near diagnosis, and 28.5% occurring around relapse. The mean age was 64.9 years, 58.6% were male, and additional patient characteristics are presented in Table 1. There were 33.8% (n=183) pts with DS&amp;lt;4, 30.9% (167) with DS 4-6, and 35.3% (191) with DS of ≥7. The highest scoring EDS symptoms were pain (mean score 4.7), fatigue (5.1) and sleep disturbance (3.6). Broadly, patients with higher distress scores had higher symptom scores (p&amp;lt;0.05 for all symptoms). There were 77.6% (420) pts with anxiety GAD-2 score of 0-2, 12.9% (70) pts with a score of 3-4 and 9.4% (51) pts with a score of 5-6. Similarly, for depression, 76.9% (416) pts reported a PHQ-2 score of 0-2, 15% (81) with a score of 3-4, and 8.1% (44) with a score of 5-6. For anxiety and depression, patients with higher DS had higher depression and anxiety screening scores (p &amp;lt;0.001), as shown in Table 2. 64.3% (348) pts utilized at least one SS within six months of their initial EDS assessment. The rate of utilization of at least one SS increased with DS (49.2% in DS &amp;lt;4, 67.1% in DS 4-6, and 76.7% in DS ≥7; p value&amp;lt;0.001). Numerically, more patients with high distress had at least one ED visit within a year of EDS (25.7% DS &amp;lt;4, 33.5% DS 4-6, 36.1% DS ≥7, p = 0.08). There was no significant difference in hospitalization within 1 year between the DS groups. There were 147 (36.8%) pts with high-risk cytogenetics, of which 43.5% had a distress score of ≥7. The rate of utilization of SS, ED visits, and hospitalizations was numerically higher in pts with newly diagnosed MM (68.5%, 34.4%, 63.1%, respectively), as compared to pts with RRMM (64.3%, 25.3%, 48.7%). Conclusion: The disease-specific symptoms predict clinically significant DS &amp;gt;4 on EDS. There were about 20% of pts with screening score &amp;gt;2 for anxiety (GAD-2) &amp; depression (PHQ-2) that may warrant further exploration regarding the detail and nature of symptoms related to the diagnosis. There was a higher rate of utilization of SS and ED visits in pts with higher DS. Given these findings, there is a need to identify the optimal healthcare pathways for better utilization &amp; incorporation of these EDS and PROs in the clinical care of distressed patients. Our study indicates that more work is needed to align needs with resources in order to optimize quality of life and disease outcomes for our pts.

Incidence and Prognosis of Congenital Cytomegalovirus Infection, a Retrospective Single-Center Experience, Tehran, Iran

Background: Congenital cytomegalovirus (cCMV) is the most common intrauterine viral infection, affecting up to 2.5% of live births worldwide; it is also the most common non-hereditary cause of sensorineural hearing loss (SNHL) in infants. Objectives: This study aimed to evaluate the frequency of cCMV and the incidence of sensorineural hearing loss at a large referral hospital in Tehran. Methods: In our cross-sectional study, all infants born between March 2019 and April 2020 (one year) at Mahdiyeh Obstetrics and Gynecology Hospital were enrolled in the present study, and their urine samples were collected for CMV PCR in the first 2 days of life. PCR test results divided these infants into two groups, with and without congenital cytomegalovirus infection. For both groups, the otoacoustic emission screening test (OAE) was performed at birth and one month of age; the auditory brain response test (ABR) was then performed for infants with hearing impairment. Results: Urine samples of 859 were collected for cytomegalovirus PCR testing; 70.3% of specimens were from male infants. Neonatal urine samples were tested for the presence of cytomegalovirus by PCR; 847 of the specimens (98.6%) were negative, and 12 (1.4%) were positive for cytomegalovirus, CI: (95%). The prevalence of congenital cytomegalovirus infection was 1.18% in girls and 1.49% in boys, revealing no significant difference between the two groups. All infants with congenital cytomegalovirus infection were full-term, between 38 and 42 weeks of gestational age. The first OAE test was impaired in 4 cases (33%) with congenital cytomegalovirus infection. Conclusions: In our study, congenital CMV infection prevalence was 1.4%. We recommend hearing screening tests (OAE and AABR) be performed for all neonates. If impaired, the infant should also be evaluated for cCMV infection in addition to auditory follow-up. It is recommended that this study be continued in a multicenter manner with a larger number of samples and a longer period to fully evaluate the prevalence of complications in cCMV.

Investigating infectious outcomes in adult patients undergoing solid organ transplantation: A retrospective single-center experience, Paris, France.

This study described the demographic characteristics, clinical presentation, treatment, and outcomes of solid organ transplant recipients who were admitted to our center for infection. It also determined factors associated with a poor outcome, and compares early and late period infections. In this retrospective observational study, conducted at a tertiary care center in France between October 2017 and March 2019, infectious outcomes of patients with solid organ transplant where studied. A total of 104 patients were included with 158 hospitalizations for infection. Among these 104 patients, 71 (68%) were men. The median age was 59 years old. The most common symptoms on admission were fever (66%) and chills (31%). Lower respiratory tract infections were the most common diagnosis (71/158 hospitalizations). Urinary tract infections were frequently seen in kidney transplant recipients (25/60 hospitalizations). One or more infectious agents were isolated for 113 hospitalizations (72%): 70 bacteria, 36 viruses and 10 fungi, with predominance of gram-negative bacilli (53 cases) of which 13 were multidrug-resistant. The most frequently used antibiotics were third generation cephalosporins (40 cases), followed by piperacillin-tazobactam (26 cases). We note that 25 infections (16%) occurred during the first 6 months (early post-transplant period). Patients admitted during the early post-transplant period were more often on immunosuppressive treatment with prednisone (25/25 VS 106/133) (p = 0.01), mycophenolic acid (22/25 VS 86/133) (p = 0.03), presented for an urinary tract infection (10/25 VS 25/133) (p = 0.04) or a bacterial infection (17/25 VS 53/133) (p = 0.01). Patients with later infection had more comorbidities (57/83 VS 9/21) (p = 0.03), cancer (19/83 VS 0/21) (p = 0.04) or were on treatment with everolimus (46/133 VS 0/25) (p = 0.001). During 31 hospitalizations (20%), patients presented with a serious infection requiring intensive care (n = 26; 16%) or leading to death (n = 7; 4%). Bacteremia, pulmonary and cardiac complications were the main risk factors associated with poor outcome. Infections pose a significant challenge in the care of solid organ transplant patients, particularly those with comorbidities and intensive immunosuppression. This underscores the crucial importance of continuous surveillance and epidemiologic monitoring within this patient population.

Application of double layer with collagen-elastin matrix (Matriderm®) and polyglycolic acid sheet (Neoveil®) for oroantral and oronasal fistula closure after maxillectomy: a retrospective single center experience

PurposeThis study investigates the effectiveness of a new double-layer approach for closing oroantral and oronasal fistulas (OA/ONFs) using Matriderm® and Neoveil®. Matriderm®, an acellular dermal matrix composed of collagen and elastin fibers, supports tissue regeneration, while Neoveil®, a biodegradable mesh sheet, serves as a barrier to prevent leakage and scarring. Material and MethodsA retrospective study of 12 maxillectomy patients with oral cancer between January 2022 and May 2023 was conducted. Patient data, including tumor stage, bone invasion, and defect size, were analyzed. Surgical techniques included sinus mucosa preservation, and either buccal fat grafting combined with the double layer technique or the double layer technique alone, with statistical analysis performed using R software to evaluate outcomes. ResultsThe results indicate a 41.7% incidence rate of fistula formation with lower T stages, absence of bone invasion, smaller defect dimensions, and intact sinus mucosa correlating with reduced fistula risk (p < 0.05). Notably, no patients required fistula-related surgical revisions, validating the efficacy of the approach. ConclusionThis study introduced a novel double-layer technique using Matriderm® and Neoveil® for closing OA/ONFs after maxillectomy. The technique demonstrated promising outcomes in addressing these post-operative complications. Lower tumor stages, no bone invasion, smaller defects, and intact sinus mucosa correlated with reduced fistula risk. This technique holds potential to enhance maxillectomy outcomes, offering a comprehensive approach to functional concerns, but warrants further investigation.
