Clinical Significance of Low Volume Lymph Node Metastasis in Early Stage Cervical Cancer: A Single Centre Case Series

Background and Objectives: Lymph node involvement is uncommon in early-stage cervical cancer (7-20%), with low volume nodal disease (micrometastasis and isolated tumour cells) representing a further small subset (2-23%) of this small population. Fewer data are available on the impact of low volume metastasis in cervical cancer. The current consensus is to treat this group of patients in the same way as for nodal macrometastasis although the prognostic significance of low volume lymph node metastasis still remains contested. The purpose of this study was to retrospectively analyze a cohort of patients who underwent primary surgery for early-stage cervical cancer and where the post operative histopathology report demonstrated low volume lymph node metastasis. The aim was to determine the frequency of recurrence and progression free survival in groups with isolated tumor cells (<0.2 mm), micrometastasis (0.2 – 2 mm) and macrometastasis (>2 mm). Methods: Retrospective review had identified 18 patients who underwent primary surgery in single Gynaecology Cancer Centre between 2007 and 2018 for cervical cancer with subsequent histologically demonstrated lymph node metastasis. Progression free survival curves were generated for each patient group based on their histological type of lymph node metastasis. Log rank, chi squared test statistic was calculated to test for statistically significant difference in survival between groups. Results: A total of 18 patients were identified as having isolated tumor cells (n=7), micrometastasis (n=5) or macrometastasis (n=6) on post operative lymph node histopathology. Follow up data demonstrated a total of 6 recurrences overall, with the highest number in the “macrometasitasis“ group (66.7%), followed by “isolated tumor cells” group (28.6%). No recurrence was observed in the “micrometastasis” group. The difference in progression-free survival between groups was not statistically significant at alpha = 0.05 (p=0.0685). Conclusion: Further research and larger studies are required to evaluate the prognostic significance and the overall outcome in patients with isolated tumor cell lymph node metastasis in early stage cervical cancer.

Diagnostic pathway and management of first seizures in infants with Sturge-Weber syndrome.

Sturge-Weber syndrome (SWS) is a rare neurocutaneous syndrome, frequently associated with pharmaco-resistant, early-onset epilepsy. Optimal seizure control is paramount to maximize neurodevelopment. A single-centre case series of 49 infants explored early SWS care. Ninety-two per cent of children developed seizures aged 0 to 3 years; 55% of cases were before diagnostic magnetic resonance imaging (MRI) or tertiary referral. Delay in SWS diagnosis affected 31% of infants because of a lack of gadolinium enhancement for initial MRI. First seizures were frequently prolonged, with phenytoin administration necessary in 46%. Presymptomatic antiseizure medication prophylaxis (n = 8/49) decreased seizure burden. No patients on antiseizure medication prophylaxis suffered status epilepticus for longer than 30 minutes, and half of them (n = 4) had not developed seizures at last follow-up (aged 2-10 years). A parental survey enabled further service evaluation. Eighty-three per cent of parents considered local clinicians' understanding of SWS inadequate: 61% felt insufficiently informed about SWS and 81% received no epilepsy education before seizures. To overcome the identified shortfalls, guidelines towards improving and standardizing SWS management are proposed.

Challenges in prompt identification and surgical correction of Marfan Syndrome aortic disease in a middle-income country: a case series study

BackgroundMarfan Syndrome is an autosomal dominant disease caused by pathogenetic variants in the FBN1 gene. The progressive dilatation of the aorta and the potential risk of acute aortic syndromes influence the prognosis of these patients. We aim to describe population characteristics, long-term survival, and re-intervention patterns in patients who underwent aortic surgery with a previously confirmed clinical diagnosis of Marfan Syndrome in a middle-income country.MethodsA retrospective single-center case series study was conducted. All Marfan Syndrome patients who underwent aortic procedures from 2004 until 2021 were included. Qualitative variables were frequency-presented, while quantitative ones adopted mean ± standard deviation. A subgroup analysis between elective and emergent procedures was conducted. Kaplan-Meier plots depicted cumulative survival and re-intervention-free. Control appointments and government data tracked out-of-hospital mortality.ResultsFifty patients were identified. The mean age was 38.79 ± 14.41 years, with a male-to-female ratio of 2:1. Common comorbidities included aortic valve regurgitation (66%) and hypertension (50%). Aortic aneurysms were observed in 64% without dissection and 36% with dissection. Surgical procedures comprised elective (52%) and emergent cases (48%). The most common surgery performed was the David procedure (64%), and the Bentall procedure (14%). The in-hospital mortality rate was 4%. Complications included stroke (10%), and acute kidney injury (6%). The average follow-up was 8.88 ± 5.78 years. Survival rates at 5, 10, and 15 years were 89%, 73%, and 68%, respectively. Reintervention rates at 1, 2.5, and 5 years were 10%, 14%, and 17%, respectively. The emergent subgroup was younger (37.58 ± 14.49 years), had the largest number of Stanford A aortic dissections, presented hemodynamic instability (41.67%), and had a higher requirement of reinterventions in the first 5 years of follow-up (p = 0.030).ConclusionIn our study, surveillance programs played a pivotal role in sustaining high survival rates and identifying re-intervention requirements. However, challenges persist, as 48% of the patients required emergent surgery. Despite not affecting survival rates, a greater requirement for reinterventions was observed, emphasizing the necessity of timely diagnosis. Enhanced educational initiatives for healthcare providers and increased patient involvement in follow-up programs are imperative to address these concerns.

Transarterial embolization of uterine arteries in emerging dysfunctional uterine bleeding: a single-center case series study

BackgroundUterine artery embolization is proven to be an effective treatment for symptomatic uterine fibroids. Yet, its role in the management of dysfunctional uterine bleeding is still debatable. Patients with dysfunctional uterine bleeding have abnormal bleeding from the uterine vascular bed with variable underlying mechanisms. Uterine artery embolization will reduce/prevent bleeding by occlusion of the vascular bed, with subsequent cutoff of the effect of hormones on the endometrium. The aim of this work is to demonstrate the safety, efficacy and possible short-term complications of uterine artery embolization in the treatment of dysfunctional uterine bleeding (DUB) as a first-line treatment modality rather than the current treatment options (hormonal and surgical treatment).MethodsThirty patients included in the study were clinically and laboratory diagnosed based on FIGO classification system (PALM-COEIN) as DUB, and the diagnosis was confirmed by MRI imaging. All patients were subjected to transcatheter uterine artery embolization with subsequent clinical and radiological follow-up to assess the treatment outcome.ResultsUterine artery embolization was able to control bleeding in patients diagnosed as DUB, with subsequent complete cessation of medical treatment; no surgical interference was needed with much less morbidity. We had 93.3% improvement in the frequency, volume of bleeding and 100% improvement of the presenting anemia. No significant change in uterine volume or in endometrial thickness has been noted.ConclusionsUterine artery embolization is safe, effective procedure to control dysfunctional uterine bleeding with the preservation of the uterus especially in critical age groups.

Usage of Meropenem Continuous Infusion for Treatment of Infectious Complications in Orthopedic Elderly Patients with Anemia: A Case Series.

Background and Objectives: The prolonged infusion of meropenem is recommended by guidelines for the treatment of sepsis. However, studies provide controversial data on the advantages of prolonged infusions over intermittent ones. In our opinion, this can be related to age, which possibly distorts the final data, as older people have age-related characteristics. In our study, we analyzed the ventilatory status, laboratory tests and vital signs of the patient and carried out microbiological cultures. Materials and Methods: This was a prospective single-center case series investigation conducted from June 2022 to June 2023. The objective of this study was to evaluate the effectiveness of continuous infusion in elderly patients with severe infectious complications after orthopedic interventions. The primary endpoints were 28-day survival and the emergence of new multidrug-resistant strains. Secondary endpoints were long-term mortality and length of stay in the ICU. Results: Three patients (median age 65, 100% female) received a continuous infusion of meropenem. Two patients were alive at hospital discharge, and one patient died on the 105th day of hospitalization. Multi-resistant bacteria were observed in one patient. Conclusions: The use of a continuous meropenem infusion in the complex treatment of purulent-septic complications in elderly patients with periprosthetic infection and anemia probably led to clinical improvement in these case reports. However, the emergence of new pan-resistant strains and overall mortality using this infusion technique remains unclear. Further, high-quality RCTs for the elderly are needed.

Obstacles to receiving postoperative radiation therapy following separation surgery for metastatic spine disease.

Obtaining timely postoperative radiotherapy (RT) following separation surgery is critical to avoid local recurrence of disease yet can be a challenge due to scheduling conflicts, insurance denials, and travel arrangements. In patients undergoing metastatic spine surgery for spinal cord compression, the authors sought to: 1) report the rate of postoperative RT, 2) describe reasons for patients not receiving postoperative RT, and 3) investigate factors that may predict whether a patient receives postoperative RT. A single-center retrospective case series was undertaken of all patients who underwent metastatic spine surgery for extradural disease between January 2010 and January 2021. Inclusion criteria were patients with intermediate or radioresistant tumors with evidence of spinal cord compression who underwent surgery. The primary outcome was the occurrence of RT within 3 months following surgery. Multivariable logistic regression analysis was performed controlling for age, BMI, race, total number of decompressed levels, tumor size, other organ metastasis, and preoperative RT or chemotherapy to predict patients receiving postoperative RT. Of 239 patients undergoing spine surgery for metastatic disease, 113 (47.3%) received postoperative RT while 126 (52.7%) did not. In the postoperative RT group, 24 (21.2%) received stereotactic body radiation therapy while 89 (78.8%) received conventional external-beam radiation therapy. The most common reasons for patients not receiving postoperative RT included death or transfer to hospice (31.0%), RT not being recommended by radiation oncology (30.2%), and loss to follow-up (23.8%). On critical review with the radiation oncology department, the authors estimated that 101 of 126 (80.2%) patients who did not receive postoperative RT were potential candidates for postoperative RT. Patients who received postoperative RT had more documented inpatient (48.7% vs 32.5%, p < 0.001) and outpatient (100.0% vs 65.1%, p < 0.001) radiation oncology consultations than those who did not. Additionally, patients who received postoperative RT had a higher rate of postoperative chemotherapy (53.1% vs 25.4%, p < 0.001), while patients who did not receive postoperative RT had a higher rate of preoperative RT (7.1% vs 31.0%, p < 0.001). Multivariable analysis confirmed that patients who received preoperative RT had lower odds of undergoing postoperative RT (OR 0.14, 95% CI 0.06-0.34; p < 0.001), and patients who underwent postoperative chemotherapy had higher odds of undergoing postoperative RT (OR 3.83, 95% CI 2.05-7.17; p < 0.001). In the current study reflecting real-world care of patients with metastatic spine disease after undergoing separation surgery, 47% of patients did not receive postoperative RT, and 80% of those patients were potential candidates for postoperative RT. Radiation oncology consultation and postoperative chemotherapy were significantly associated with receiving postoperative RT, whereas preoperative RT was significantly associated with not receiving postoperative RT. The lack of timely postoperative RT highlights a potential gap in metastatic spine tumor care and underscores the necessity for prompt radiation oncology consultation and effective planning.

Venetoclax combined with hypomethylating agents for favorable risk acute myeloid leukemia: A single center experience.

e18514 Background: Favorable risk acute myeloid leukemia (FR-AML) is typically treated with intensive induction chemotherapy followed by high dose consolidative cytarabine. However, a subgroup of FR-AML are not candidates for high intensity induction because of advanced age, comorbidities, or poor performance status. For these patients, hypomethylating agents (HMA) combined with venetoclax (HMA-Ven) is inferred as the standard of care based upon results of the VIALE-A trial; however, that trial enrolled only intermediate or poor risk AML. The efficacy of HMA-Ven in FR-AML is unclear. Here we present a single center experience of this regimen in FR-AML. Methods: In this retrospective single center case series, we collected data from all patients &gt;18 years old with newly diagnosed FR-AML between January 2018 to December 2022 at AdventHealth Orlando who were treated with HMA-Ven. Patient with relapsed/refractory disease or a diagnosis of acute promyelocytic leukemia were excluded. FR-AML was defined using ELN 2022 guidelines based on the results of genomic testing of the initial bone marrow aspirate. The primary endpoints were the complete remission (CR) rate and 1-year overall survival (OS). Statistical analyses were performed using the R survminer package. Results: Newly diagnosed FR-AML who received HMA-Ven were identified (n=12). The median age was 67.5 years. 3 (25%) cases had inversion of chromosome 16 and 9 (75%) had NPM1 mutations without FLT3-ITD mutations. 11 (92%) patients received decitabine and venetoclax. Patients received a median of 2.5 cycles of HMA-Ven, and all 12 patients achieved CR after one cycle of treatment. 6 (50%) patients were consolidated with intermediate-dose cytarabine (IDAC), 3 (25%) continued HMA-Ven, 2 (17%) underwent allogeneic stem cell transplant, and 1 (8%) received enasidenib. The 1-year OS was 80% (CI 0.59-1), and the median OS was not reached. 1 patient died due to chemotherapy toxicity with IDAC, and 1 patient died due to heart complications. 2 patients relapsed, 1 after IDAC and 1 after intolerance to further treatment after 6 cycles of HMA-Ven. Conclusions: Our findings suggest that HMA-Ven is an effective treatment for newly diagnosed favorable risk AML. All patients achieved CR with one cycle of treatment with most surviving more than one year. Large multicenter studies are needed to further validate these promising results.

Clinical Outcomes of a Novel Hybrid Transtibial Technique for Femoral Tunnel Drilling in Anterior Cruciate Ligament Reconstruction: A Large Single-Center Case Series With a Minimum 2-Year Follow-up.

A novel hybrid transtibial (HTT) approach to femoral tunnel drilling in anterior cruciate ligament reconstruction (ACLR) has been developed that circumvents the need for knee hyperflexion and orients the graft in the most anatomic position without sacrificing the tunnel length or aperture. Patients who underwent ACLR utilizing the HTT technique would achieve excellent patient-reported outcome scores and experience low rates of graft failure and reoperations. Case series; Level of evidence, 4. Patients who underwent primary ACLR at a single institution between 2005 and 2020 were retrospectively reviewed. Patients treated with the HTT, anteromedial portal (AMP), and transtibial (TT) approaches were matched based on age, sex, and body mass index ±3 kg/m2. Demographic and surgical data as well as femoral tunnel angle measurements on anteroposterior and lateral radiographs were collected for the 3 groups. However, clinical outcomes were only reported for the HTT group because of concerns of graft heterogeneity. A total of 170 patients (median age, 26.5 years [interquartile range (IQR), 18.0-35.0 years]) who underwent ACLR using the HTT approach were included. The median coronal- and sagittal-plane femoral tunnel angles were 47° (IQR, 42°-53°) and 40° (IQR, 34°-46°), respectively. The sagittal-plane femoral tunnel angles in the HTT group were significantly more horizontal compared with those in the TT group (P < .0001), whereas the coronal-plane femoral tunnel angles in the HTT group were found to be significantly more vertical compared with those in the AMP group (P = .001) and more horizontal compared with those in the TT group (P < .0001). The graft failure and reoperation rates in the HTT group at a minimum 2-year follow-up were 1.8% (3/170) and 4.7% (8/170), respectively. The complication rate was 6.5% (11/170), with the most common complication being subjective stiffness in 7 patients. The median Lysholm score was 89.5 (IQR, 79.0-98.0); the median International Knee Documentation Committee score was 83.9 (IQR, 65.5-90.8); and the median Veterans RAND 12-Item Health Survey physical and mental component summary scores were 55.0 (IQR, 52.6-55.9) and 56.2 (IQR, 49.1-59.3), respectively. ACLR using the HTT technique was associated with low graft retear and revision surgery rates and good patient-reported outcome scores at medium-term follow-up and demonstrated femoral tunnel obliquity on postoperative radiographs that correlated with optimal parameters previously reported in cadaveric and biomechanical studies.

A Single-Center Case Series of Acute Retinal Necrosis at Teikyo University: Clinical Characteristics and Treatment Outcomes.

Aim To evaluate the clinical characteristics, treatment course, and prognosis of patients with acute retinal necrosis (ARN), which can rapidly progress and cause severe vision loss. Design Single-center retrospective case series. Subjects and methods Six patients and seven eyes diagnosed with ARN at Teikyo University Hospital were included in this study. The clinical presentation and treatment prognosis were investigated based on data obtained from medical records. Results The mean age of the patients at the initial diagnosis was 63.6 years. Although the mean Logarithm of the Minimum Angle of Resolution (LogMAR) visual acuity tended to decrease from 0.77 at the first visit to 1.29 at the last visit, the difference was not statistically significant. Intraocular manifestations observed during the study period included ocular hypertension (14.3%), anterior uveitis (100.0%), retinal hemorrhage (71.4%), vitreous opacity (100.0%), retinal exudative vasculitis (85.7%), optic nerve atrophy (85.7%), retinal vascular occlusion (85.7%), choroidal atrophy (85.7%), macular edema (100.0%), subretinal fluid in the macula (71.4%), and retinal detachment (85.7%). Treatment modalities included oral and intravitreal antivirals (85.7%), antiplatelet medications (85.7%), steroid eye drops (85.7%), subcapsular (57.1%) and vitreous (42.9%) steroid injections, oral steroids (71.4%), and surgical intervention (85.7%). Vitrectomy led to retinal recovery in all five eyes that underwent the procedure. Conclusions The visual prognosis of patients with ARN is poor, particularly in those with preexisting visual impairment. Early detection coupled with antiviral therapy and prompt surgical intervention have been identified as potential factors that influence visual outcomes. Given the severity of ARN, collecting data from multiple centers could aid in devising future diagnostic and therapeutic strategies.

Dorsal root entry zone lesioning for brachial plexus avulsion - technical evolution and long-term follow-up.

Brachial plexus avulsion (BPA) injuries can cause severe deafferentation pain. This has been successfully treated with dorsal root entry zone (DREZ) lesioning. Distortions in anatomy following a BPA injury can make identifying neural structures challenging. We describe a modification to the operative technique that improves the surgical view and the advanced intraoperative neuromonitoring (IONM) employed to identify DREZ. We have analysed the long-term outcomes for pain, quality of life, and complications in patients undergoing DREZ lesioning. This is a single-centre retrospective case series including patients who underwent DREZ lesioning with IONM for brachial plexus avulsion between 2012 and 2022. Analysed data included pre- and postoperative pain (VAS), quality of life score for chronic pain, and complications. The evolution of the surgical approach is discussed. 44 consecutive patients underwent a DREZ lesioning procedure with intraoperative monitoring and mapping. In these patients the mean VAS score improved from 8.9 (7-10) to 1.87 (0-6) (p < 0.0001) at the time of discharge. 31 patients were followed-up for more than 12 months with a mean duration of follow-up of 41 months and their results were as follows: the mean VAS improved from 9.0 (7-10) to 4.1 (0-9) (p < 0.0001) at the last follow-up and the mean QOL values improved from 3.7 (2-6) to 7.4 (4-10) (p < 0.0001). The long-term outcomes were 'good' in 39%, 'fair' in 29% and 'poor' in 32% of patients. 55% of the patients were able to stop or reduce pain medications. Modifications of surgical technique provide better exposure of DREZ, and IONM aids in identifying DREZ in the presence of severe intra-dural changes. Long-term outcomes of DREZ lesioning indicate not only a reduction in pain but also a significant improvement in quality of life.

Regorafenib in patients with pretreated advanced melanoma: a single-center case series.

Melanoma patients failing all approved treatment options have a poor prognosis. The antimelanoma activity of regorafenib (REGO), a multitargeted kinase inhibitor, has not been investigated in this patient population. The objective response rate and safety of REGO treatment in advanced melanoma patients was investigated retrospectively. Twenty-seven patients received REGO treatment. All patients had progressed on anti-programmed cell death protein 1 (PD-1) and anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) checkpoint inhibition and BRAF/MEK inhibitors (in case of a BRAF V600 mutation). REGO was administered in continuous dosing and combined (upfront or sequentially) with nivolumab ( n = 5), trametinib ( n = 8), binimetinib ( n = 2), encorafenib ( n = 1), dabrafenib/trametinib ( n = 9), or encorafenib/binimetinib ( n = 7). The best overall response was partial response (PR) in five patients (18.5%) and stable disease in three patients (11.1%). Three of seven (42.8%) BRAF V600mut patients treated with REGO in combination with BRAF/MEK inhibitors obtained a PR (including regression of brain metastases in all three patients). In addition, PR was documented in a BRAF V600mut patient treated with REGO plus anti-PD-1, and a NRASQ61mut patient treated with REGO plus a MEK inhibitor. Common grade 3-4 treatment-related adverse events included arterial hypertension ( n = 7), elevated transaminase levels ( n = 5), abdominal pain ( n = 3), colitis ( n = 2), anorexia ( n = 1), diarrhea ( n = 1), fever ( n = 1), duodenal perforation ( n = 1), and colonic bleeding ( n = 1). Median progression-free survival was 11.0 weeks (95% confidence interval, 7.1-14.9); median overall survival was 23.1 weeks (95% confidence interval, 13.0-33.3). REGO has a manageable safety profile in advanced melanoma patients, in monotherapy as well as combined with BRAF/MEK inhibitors or PD-1 blocking monoclonal antibodies. The triplet combination of REGO with BRAF/MEK inhibitors appears most active, particularly in the BRAF V600mut patients.

Acute Appendicitis in Children with Hematological Malignancies: The Need for Early Diagnosis and Prompt Treatment—A Single-Center Case Series

Abstract Introduction Appendicitis in patients with hematological malignancies presents with vague symptoms, thus requiring a high degree of suspicion for early diagnosis and treatment to prevent complications. Objectives The aim of this article was to describe the demographic, clinicoradiological, operative findings, and outcomes in patients with acute appendicitis with underlying hematological malignancies. Materials and Methods A retrospective review of pediatric patients with hematological malignancy who developed acute appendicitis was conducted. Medical records of patients were reviewed for patient demographics, disease status, signs, and symptoms at the time of diagnosis of acute appendicitis, and outcome. The laboratory, radiological, and histological findings were retrieved from the hospital records. Results Six (2.4%) patients developed acute appendicitis over the past 8 years among a total of 254 patients treated for hematological malignancies in the unit. Five patients had underlying acute lymphoblastic leukemia (ALL) and one had acute myeloid leukemia (AML). Of the five patients, three were in postremission consolidation, one each in the delayed intensification and maintenance phase of chemotherapy. The child with AML was on induction chemotherapy for the first relapse at the time of diagnosis. Fever and abdominal pain were the common presenting symptoms. Diagnosis was made on ultrasound abdomen in five patients, and one patient was diagnosed on computed tomography. All patients underwent open appendectomy. Two patients had evidence of appendiceal perforation. Three patients had neutropenia at the time of developing appendicitis and underwent appendectomy regardless of the absolute neutrophil count (ANC). Five patients recovered well, and chemotherapy was restarted within 2 weeks of appendectomy. One patient developed a superficial surgical site infection. and one patient with relapsed AML expired due to refractory septic shock. Conclusion Acute appendicitis in patients with hematological malignancies can present with subtle signs and symptoms. Appendectomy can be safely performed irrespective of the ANC.

Clinical characterization of pediatric acute confusional migraine: a single-center case series.

Acute confusional migraine (ACM) is a rare disorder characteristic of pediatric patients. Our objective was to describe the clinical characteristics of patients diagnosed with ACM who visited our pediatric emergency department (PED). This study was a retrospective review of children who presented to our PED between January 2012 and December 2022 with a discharge diagnosis of ACM. During the study period, 23 patients were enrolled: 11 males (47.8%) and 12 females (52.2%); median age was 10.8years (IQR: 8.3-13.6). Eight patients reported a history of headache. The median length of stay of PED was 4.7h. Onset was abrupt (less than 12h) in 100% of cases. Changes in the level and content of consciousness occurred in 47.8% and 91.3% of patients, respectively; confusion (73.9%) was the most common neurological manifestation. Eighteen patients had urgent brain CT scans, none showing pathological findings. Four patients required benzodiazepines to control their psychomotor agitation. Nine patients were hospitalized, including one in the intensive care unit. Two patients underwent MRI and one patient underwent EEG during hospitalization, with normal results. ACM is a rare condition in pediatric neurology characterized by acute onset of confusion or altered mental status before, during, or after migraine headache. Clinical features overlap with other neurological disorders, making diagnosis challenging. To improve the diagnosis, treatment, and research of AMC, it is essential to include it in the International Classification of Headache Disorders and establish standardized diagnostic criteria.

Feasibility and complications after transoral endoscopic thyroidectomy via vestibular approach (TOETVA) - a single-center first experience case series.

This paper reports on the first experience after implementation of a transoral endoscopic thyroidectomy via vestibular approach (TOETVA) as an alternative to (partial) thyroidectomy or isthmusectomy in a single center. Feasibility, implementation and specific complications are addressed. All patients who underwent a TOETVA procedure in our center between November 2019 and March 2023 were included. The surgical technique was performed as described by Anuwong et al. All procedures were performed by two dedicated head- and neck surgeons. A total of 20 patients were included. All patients underwent TOETVA surgery as planned and no conversions were needed. Observed complications were post-operative wound infections (POWI) (2/20; 10%), clinically significant seroma (1/20, 5%) and unilateral hemiparesis of the larynx (3/20; 15%). Permanent mental nerve damage was seen in 3/20 patients (15%), and 4 other patients (20%) experienced transient neuropraxia. TOETVA is a feasible alternative to (partial) thyroidectomy or isthmusectomy in selected patients. Special care should be taken when placing the trocars in the oral vestibulum to prevent mental nerve damage. Experience and training are essential for implementing the TOETVA procedure. This study was registered to ClinicalTrials.gov. NCT05396703.

Anti-aging Effects of Tirbanibulin 1% Ointment: A Real-Life Experience.

Tirbanibulin 1% ointment has been licensed to treat non-hyperkeratotic actinic keratosis (AKs) on the face and scalp in adults to ensure excellent patient tolerability due to the mild side effects and the brief application time compared to other topical therapies on the market. A growing body of evidence suggests that, beyond their primary function, the treatments for AKs and the cancerization field may inadvertently confer substantial cosmetic benefits to patients. We report a single-center retrospective case series of patients referred to the Dermatology Unit of the University Hospital of Messina, Italy, between February and December 2023 seeking treatment for AKs in the context of photodamaged areas in which the application of tirbanibulin 1% ointment induced, besides clearance of AKs, anti-aging effects on both skin texture and solar lentigos. Seven patients affected by Olsen grade1-2 AKs experienced a powerful rejuvenating effect in the treated areas, with a marked efficacy in skin lightening and clearance of solar lentigo. Tirbanibulin 1% ointment seems able to improve skin aging as a desirable side effect at the site of application for AKs on chronic photodamaged skin. Such preliminary observation needs further confirmation in real-life studies on larger cohorts of patients, to explain the pathogenic mechanisms responsible for such aesthetically relevant results.

Primary Cutaneous CD4+ Small/Medium T-Cell Lymphoproliferative Disorders (SMPLPD), demographical, clinical, therapeutic and prognostic aspects: a retrospective monocentric analysis.

Primary Cutaneous CD4+ Small/Medium T-Cell Lymphoproliferative Disorders (SMPLPD), also known as PCS-TCLPD, represent a rare group of hematologic diseases primarily affecting the skin. In this retrospective single-centre case series study, we aimed to investigate the demographic, clinical, therapeutic, and prognostic aspects of SMPLPD. We collected data from cases diagnosed between 2010 and the present, employing histopathological and immunohistochemical methods following WHO criteria. We included 22 patients with a median age of 61.50 years and median time between clinical onset and diagnosis of 3.00 months. Surgical excision with conservative margins was the primary choice, showing clinical remission in 17 cases, while non-surgical treatments, including radiotherapy, high-potency steroid treatment and ablative laser, achieved clinical remission in four cases. Clinical presentations varied, but the most common one was a single violaceous nodule/papule on upper body parts. In conclusion, our single-centre case series provides valuable insights into SMPLPD, highlighting the effectiveness of surgical treatments and the potential of non-surgical ones. Even if controversial, the benign nature of SMPLPD emphasizes the importance of achieving tumour clearance with acceptable aesthetic outcomes.

Acquired Fanconi syndrome in mixed cryoglobulinemia patients: a single-center case series.

Cryoglobulinemia is a pathological condition characterized by the presence of cryoglobulins in the blood, with cryoglobulinemic glomerulonephritis being the most frequent form of renal involvement. Fanconi syndrome presents as a generalized dysfunction of the proximal tubule, characterized by the presence of polyuria, phosphaturia, glycosuria, proteinuria, proximal renal tubular acidosis, and osteomalacia. We aimed to present five cases co-occurring with Fanconi syndrome and cryoglobulinemia. We retrospectively summarized the cases of five patients with Fanconi syndrome and cryoglobulinemia at Peking Union Medical College Hospital from January 2012 to June 2022. The clinical features, diagnosis, treatment, and prognosis were systematically analyzed. All five patients exhibited typical features of Fanconi syndrome, and cryoglobulinemia was concurrently detected in all cases. These patients also exhibit positive anti-nuclear antibody spectrum and hyperglobulinemia, and IgM constitutes the predominant monoclonal component in cryoglobulins. In addition to supplemental treatment, timely immunosuppressive therapy may potentially benefit the long-term renal prognosis of patients with this condition. Our findings highlight the rare co-occurrence of Fanconi syndrome and cryoglobulinemia in clinical practice. Despite the lack of causal evidence, the coexistence of Fanconi syndrome and tubulointerstitial injury is also noteworthy in patients with cryoglobulinemia, underscoring the importance of thorough evaluation and tailored management in patients presenting with overlapping renal manifestations. Key Points • Patients with mixed cryoglobulinemia can clinically present with tubulointerstitial injury, specifically manifesting as Fanconi syndrome. • In addition to typical symptoms of Fanconi syndrome, these patients also exhibit positive anti-nuclear antibody spectrum and hyperglobulinemia, while IgM constitutes the monoclonal component in cryoglobulins. • Timely immunosuppressive therapy may improve long-term renal prognosis in these patients.

Rare type of tracheal agenesis: Unexpected presentation and immediate consideration of emergent esophageal intubation in neonatal resuscitation program. Case reports and review of the literature.

Tracheal agenesis, or tracheal atresia, is a rare congenital anomaly. The presence of a tracheoesophageal fistula (TEF) can help with breathing for newborns with tracheal agenesis. In this article, we presented three unique cases and outcomes of neonates with tracheal agenesis along with a review of the literature. This study consisted of a single center case series followed by a review of literature. Case reports were generated using both written and electronic medical records from a single hospital. We summarized three unique cases and outcomes of neonates with tracheal agenesis and performed a review of the literature. We identified three cases of tracheal agenesis presented with severe cyanosis without spontaneous crying upon birth. Experienced pediatricians attempted to intubate the babies but were unsuccessful. Endotracheal tubes were subsequently either accidentally or purposely placed into the esophagus, and oxygen saturation levels improved. This suggested tracheal agenesis with TEF. Two cases underwent surgical intervention after resuscitation with esophageal intubation. Esophageal intubation may be a life-sustaining ventilation support for patients with tracheal agenesis and TEF at initial resuscitation. Clinicians should suspect tracheal agenesis when a newborn presents with severe cyanosis and voiceless crying upon birth, and esophageal intubation should be immediately attempted.

Percutaneous endovascular intervention for left ventricular assist device outflow graft obstruction: A single-center experience

BackgroundOutflow graft obstruction (OGO) is an uncommon yet life-threatening complication in patients with left ventricular assist devices (LVADs). In this retrospective, single-center case series, we identify the baseline demographics and presenting features of patients who develop LVAD OGO and the procedural details and outcomes surrounding percutaneous endovascular intervention (PEI). MethodsWe conducted a retrospective review of patients with LVADs at our institution between January 2010 and February 2023 who developed OGO and were treated with PEI. Details of the PEI including procedure time, fluoroscopy time, contrast use, stent size, number of stents, change in gradient, and change in flow after intervention were collected. ResultsA total of 12 patients who had 14 cases of OGO were identified from January 2010 to February 2023. The average age at presentation was 64.78 years. Nine of the 14 cases occurred in male patients. Eleven of the 14 cases occurred with Heartware devices (2 recurrences), 2 in Heartmate 2 and 1 in Heartmate 3. Notable procedural details include a mean procedure time of 90.86 min and mean contrast use of 162.5 mL. The initial gradient across the OGO was reduced by an average of 72 %, to a mean post-PEI of 11.57 mmHg. The average number of stents to achieve this gradient was around 2.08, with the most common stent diameter being 10 mm. Thirty-day mortality after PEI was 7 % (1/14) in this high-risk patient population. ConclusionIn our single-center experience, PEI can be a safe and effective treatment for LVAD OGO.
