In-hospital outcomes of ventricular tachycardia catheter ablation in the presence of intra-cardiac thrombus

Abstract Background Ventricular tachycardia (VT) catheter ablation in the presence of intracardiac thrombi was evaluated in very few studies. Objectives To investigate in-hospital outcomes of VT ablation in the presence of an intracardiac thrombus, in a large inpatient US registry. Methods Using the National Inpatient Sample (NIS) database, patients who underwent non-elective VT catheter ablations in the US between 2016 and 2019 were identified using ICD-10 codes. Sociodemographic, clinical data, in-hospital procedures and outcomes as well as in-hospital mortality were collected. In-hospital outcomes were compared using propensity score (PS) matching analysis with a 1:3 ratio between patients with and without intracardiac thrombus. Results A weighted total of 15,725 admissions for non-elective VT ablation were included in the study, of which 190 (1.2%) had a discharge diagnosis of intracardiac thrombus. Patients with intracardiac thrombus had a higher comorbidity burden and were more likely to have ischemic cardiomyopathy and a diagnosis of cardiac aneurysm. In PS analysis, the presence of intracardiac thrombus was significantly associated with higher rates of any in-hospital complications (42.1% vs 19.3%, P<0.009), driven by higher periprocedural cerebrovascular accident and vascular injury events. In-hospital mortality rates were not significantly different between the groups. Conclusions In patients undergoing non-elective VT ablation, intracardiac thrombus was associated with higher rates of in-hospital complications, but not higher in-hospital mortality. These findings suggest that intracardiac thrombus should not contraindicate VT ablation when deemed necessary, while efforts should be made to decrease potential complications.

Transanal total mesorectal excision: Understanding indications, managing complications, and effective prevention methods

AbstractTransanal total mesorectal excision (TaTME) has emerged as a surgical method for treating rectal malignancies in the middle and lower third of the rectum over the past 15 years. This approach was adopted because of the challenges encountered in secure total mesorectal excision (TME). Patient selection criteria and the rationale for TaTME have evolved, leading to improved oncological outcomes and patient quality of life. The procedure includes inserting a unique platform through the anus, forming a purse‐string closure, and endoscopically sealing the lower rectum. The mesorectum is then removed laparoscopically following a ‘down‐to‐up’ approach, finalised with a transabdominal laparoscopic phase and anastomosis. Pelvic anatomy complexity poses challenges, including potential injuries to the urinary tract, surgical site leakage, sinus damage, sagittal vein harm, nerve injury, carbon dioxide embolism, bowel function disturbance, sphincter mechanism issues, and rectal abscess formation. Proficient anatomy knowledge, precise surgical techniques, and advanced technologies contribute to their prevention. In conclusion, TaTME offers a promising approach to rectal surgery with satisfactory oncological outcomes. However, vigilance is required to eliminate potential complications.

Eagle Syndrome: The Huge Socioprofessional Impact of a Minor Lengthening of the Styloid Process

agle Syndrome (ES) is a rare clinical condition presenting with anterolateral neck pain and potential serious complications. This case report details a head nurse in the emergency room (ER) with a severe throbbing headache, trismus, left-sided dysphagia, left otalgia, gum pain, and a very intense left-sided headache, associated with ipsilateral facial hypoesthesia. The patient met the International Classification of Headache Disorders (ICHD-3) criteria for headaches attributed to inflammation of the stylohyoid ligament, establishing the diagnosis of Eagle syndrome. Chronic headaches associated with ES, as observed in this case, can impact concentration, comprehension, communication, and work performance, leading to economic loss. This prompts the question: Are individuals with ES capable of working under intense physical and psychological conditions? The paper proposes a management strategy for ES patients, emphasizing the need for further research on the impact of ES on occupational fitness, as no published studies currently address this concern.

Home cryolipolysis – A burning issue

Cryolipolysis is a non-surgical technique for fat reduction whereby adipose tissue is exposed to low temperatures to induce apoptosis. This leads to a slow reabsorption of the excess tissue. The aim of this report is to increase awareness of the burns-related risks associated with home cryolipolysis treatments, with the goal of improving regulations around such treatments and preventing similar injuries from occurring in the future. This case report highlights the potential complications associated with cryolipolysis. We present the case of a 25-year-old female with a background history of bulimia nervosa who sustained mixed-depth burns to the abdomen and upper arms following a cryolipolysis treatment. She self-delivered using an online-bought machine. Although cryolipolysis is considered a safe method for the reduction of local adiposity, it is not without risk. Burns secondary to cryolipolysis treatments have occurred, though typically by unregulated providers, not self-use as in this case. There is a need for improved regulation of the administration of cryolipolysis treatments. Health-care professionals and patients should be aware of the possible complications that can arise. Improved regulation of cryolipolysis machine purchase and use is vital to prevent machine misuse by unregulated providers and members of the public.

Knee joint dislocations-Current epidemiology and treatment in Germany.

Knee joint dislocations, though rare, present significant challenges due to potential complications like vascular and nerve damage, and are known to be often linked to sports injuries, accidents and obesity. This study aims to analyse the epidemiology, incidence and treatment approaches for knee dislocations in Germany from 2019 to 2022. This retrospective cohort study utilized data from the German Institute for the Hospital Remuneration System to examine knee dislocation cases across German medical institutions. Patient data coded under International Statistical Classification of Diseases and Related Health Problems 10 for 'knee dislocation' enabled detailed analysis by age, sex and surgical procedures categorized by operation and procedure codes. The Patient Clinical Complexity Level (PCCL) assessed complication severity. Analysis of 1643 knee dislocation cases revealed an incidence rate of 0.44-0.54 per 100,000 inhabitants annually. During the years 2020 and 2021, there were fewer cases of knee dislocations. Male patients comprised 50%-56% of cases, with an average hospital stay of 11 days. Most cases were PCCL 0 (62%-72%) and predominantly affected patients aged 18-29 years. Anterior tibial dislocations were common among classified cases. Injuries included ligament ruptures, meniscus lesions and grade I soft-tissue injuries. Patients with pre-existing knee prostheses constituted 0%-16% annually. Treatment involved closed reduction, external fixation and surgeries like capsuloligamentous reconstructions and arthroscopic procedures. Revision knee arthroplasty was required in 2%-9% of cases, with obesity rates up to 7%. This study provides valuable insights into the epidemiology, incidence and treatment of knee dislocations in Germany, with a focus on demographic risk factors, treatment complexities and the impact of obesity and knee prostheses. The findings emphasize the importance of specialized care in larger hospitals, comprehensive management of concomitant injuries and the need for improved coding accuracy. Future research should aim to refine treatment protocols. Level III.

Despite its prevalence, a global gap in diagnosis and management exists, exacerbated by the COVID-19 pandemic. This expert consensus was formulated through a comprehensive evaluation by a panel of experts, informed by a focused literature review, aiming to establish a clinically robust approach to diagnosing and managing pre- and diabetic PN with the early utilization of neurotropic B vitamins. This document offers a consensus perspective on the existing challenges in diagnosing and managing PN, focusing on DPN. The expert panel proposes measures to address this underdiagnosed burden, highlighting the importance of early intervention through innovative screening methods, integrated care approaches, and therapeutic strategies. The document advocates for increased awareness, targeted campaigns, and proactive care strategies to bridge gaps in the patient care of individuals with diabetes, emphasizing the importance of early detection and timely management to improve overall health outcomes. Specific recommendations include incorporating simplified questionnaires and innovative screening methods into routine care, prioritizing neurotropic B vitaminsupplementation, optimizing glucagon-like peptide1 (GLP-1) receptor agonist treatments, and adopting a holistic approach to neuropathy management. The consensus underscores the urgent need to address the underdiagnosis and undertreatment of PN, offering practical measures to enhance early detection and improve health outcomes for individuals with DPN.

CHARACTERISTICS AND OUTCOME OF LEFT MAIN STEM PCI AMONG WOMEN

Left main stem disease is a severe condition affecting a major coronary artery, traditionally treated with coronary artery bypass grafting. Recent advancements in percutaneous coronary intervention have made it a viable option, particularly for women who face unique risks and outcomes compared to men. Objective: This study aims to evaluate the characteristics and outcomes of percutaneous coronary intervention for left main stem disease in female patients, focusing on procedural outcomes and changes in laboratory parameters before and after the intervention. Methods: A prospective observational study was conducted from January to July 2024 with 68 female patients, aged 18 and above, from Fauji Foundation Hospital Rawalpindi. Various percutaneous coronary intervention techniques were used, and data on ejection fractions, access methods, and procedural specifics were collected. Pre- and post-procedural laboratory outcomes including haemoglobin, creatinine, platelet counts, and alanine aminotransferase levels were analyzed. Results: The mean age of participants was 63.6 years. Diabetes, hypertension, and dyslipidemia were common comorbidities. Laboratory results showed stable haemoglobin levels, slight increases in creatinine, and consistent platelet counts and ALT levels post-procedure. Statistical analysis revealed no significant changes in these parameters, indicating minimal impact on anaemia, renal function, and platelet or liver function. Conclusion: percutaneous coronary intervention for the left main stem in females generally results in stable laboratory outcomes with minimal impact on anaemia, renal function, and platelet or liver function. The procedure is safe with a low mortality rate. Continuous monitoring is recommended to manage any potential complications effectively.

Imperforate Hymen: Rare Types

When the hymen, a thin membrane of stratified squamous epithelium circumscribing the vaginal introitus, does not spontaneously rupture during neonatal development, it is referred to as an imperforate hymen. An imperforate hymen is a rare cause of primary amenorrhea and can present with obstructive symptoms of the female genital and urinary tracts during the perinatal, pediatric, or adolescent years. Timely diagnosis and prompt treatment are critical. Specific pediatric and gynecologic knowledge and skills are necessary to provide comprehensive, patient-centered care. In addition to the anatomical and physiological aspects of imperforate hymen, its clinical presentation, and potential complications, the psychological impact on affected individuals must be understood. Best practices will ultimately improve patients’ quality of life and reproductive health outcomes. This activity reviews the evaluation and treatment of imperforate hymen and highlights the role of the interprofessional team in improving care for patients with this condition.

Pregnancy care and perinatal outcomes in pregnant women with a shunt for hydrocephalus.

The number of patients with an implanted shunt reaching reproductive age and planning pregnancy is increasing thanks to advances in the treatment of hydrocephalus. Changes in the mother's organism, which are mainly related to the accumulation of water in the organism and the elevation of intra-abdominal pressure, contribute to the increased incidence of complications during pregnancy and childbirth. Therefore, it is necessary to make a preconception exam and specify pregnancy management, a suitable method of childbirth dealing with potential complications. Possible malfunction of the shunt is solved individually according to the current neurological findings and taking into account the patient's overall condition and gestational age. Vaginal delivery is considered safe and preferred by most authors. Primary caesarean section is indicated only in patients with a history of rapidly progressing deterioration of the neurological condition due to shunt malfunction or serious complications related to its impaired shunt function. In an uncomplicated pregnancy with normal values of intracranial pressure, both general and epidural or spinal anesthesia can be used when choosing anesthesia.

Indications, outcomes, and complications of orthopaedic implant removal: a prospective observational study

Background: Orthopaedic implant removal is a common procedure, but its indications and outcomes remain debated. This study aimed to examine the indications, outcomes, and complications of implant removal in a tertiary care center. Methods: A prospective observational study was conducted on 66 patients undergoing implant removal between February 2022 and February 2024. Patient demographics, indications for removal, time to removal, and complications were recorded. Follow-ups were conducted at 6 weeks, 3 months, and 6 months post-removal. Results: The study included 47 males and 19 females, with 74% adults and 26% paediatric patients. Pain was the most common indication for removal (42%), followed by elective removal (36%). Most implants (33%) were removed after 2 years. Complications were minimal, with 4.5% incomplete removals and 1.5% failure to remove. No intraoperative fractures or postoperative infections were observed. Patients generally reported improvement in symptoms or psychological well-being following implant removal. Conclusion: Implant removal should be approached selectively, with careful consideration of indications and potential complications. Pain relief and improved function were common outcomes, but risks such as incomplete removal should be considered. The study supports individualized decision-making in implant management, emphasizing the need for thorough preoperative planning and skilled surgical execution.

Evaluation of Pediatric Patients Diagnosed with Measles: A Retrospective Study in Istanbul

Abstract Objective Measles, predominantly impacting the pediatric population, manifests symptoms encompassing fever, rash, rhinorrhea, cough, conjunctivitis, accompanied by infrequent yet plausible life-threatening complications. Methods This retrospective study conducted between January 2022 and July 2023 at a 1,105-bed tertiary hospital in Istanbul, Turkey, was focused on children diagnosed with measles and aged <18 years. Cases with measles-specific immunoglobulin M antibodies or with measles virus RNA detected by polymerase chain reaction were defined as definite measles cases. Results A total of 78 pediatric patients were diagnosed with measles, of whom 40 were evaluated as definite (51.3%) cases. Among the definite cases, 29 (72.5%) and 11 (27.5%) were girls and boys, respectively. Their median age was 78 (42–158) months. It was observed that 28 (70%) patients were unvaccinated against measles, whereas data on the vaccination status of 6 (15%) patients could not be obtained. As for the symptoms, rash was observed in all diagnosed patients (100%), fever in 37 (92.5%), cough in 27 (67.5%). In addition, pneumonia was observed in 20 patients (50%). Vitamin A was administered to 5 (12.5%) patients below 2 years old. Of the patients, 29 (72.5%) were hospitalized. Three patients required intensive care unit follow-up. No mortality was recorded. When outpatients and inpatients were compared, the incidence rate of pneumonia was statistically higher in inpatients (p = 0.013). Conclusions Recent World Health Organization data reveal a surge in childhood measles instances, underscoring the imperative of bolstering vaccination rates to fortify societal immunity and safeguard individuals against potential complications.

Impact of CFTR modulatory therapies on liver function and fibrosis indices in cystic fibrosis patients: a retrospective analysis from two Romanian medical centers

Background. Patients with cystic fibrosis (CF) frequently require modulatory therapies such as Lumacaftor/Ivacaftor (LI) and Elexacaftor/Tezacaftor/Ivacaftor (ETI) to manage their condition. Given the potential hepatic complications associated with CF, it is critical to understand the impact of these therapies on liver function and fibrosis indices. This study aimed to evaluate the changes in liver function markers and fibrosis indices in CF patients undergoing LI and ETI therapies, with a specific focus on the influence of underlying hepatic disease. Methods. In this retrospective analysis, liver function markers and fibrosis indices were assessed in CF patients receiving ETI (n=24), LI (n=4), or a combination of both (LI/ETI, n=8). Key liver function markers, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, platelet count, and fibrosis indices (APRI and FIB-4), were measured at baseline and at various time points up to 12 months. Results. In patients receiving LI therapy, ALT and AST levels demonstrated a slight but non-significant decrease over six months, accompanied by significant fluctuations in total bilirubin levels. Among those receiving ETI therapy, ALT and AST levels initially increased but stabilized over time, while total bilirubin levels significantly increased from baseline to 12 months. No significant differences were observed in liver function markers between patients with and without hepatic disease under ETI therapy. Trends in fibrosis indices (APRI and FIB-4) were modest and largely non-significant across both therapies. Conclusions. ETI therapy appears to be safe for CF patients, including those with pre-existing hepatic disease, with no significant deterioration in liver function over a 12-month period. However, the observed fluctuations in bilirubin levels underscore the necessity for ongoing monitoring. Further research is warranted to investigate the long-term hepatic effects of LI and ETI therapies.

Exercise-Associated Hyponatremic Encephalopathy, Rhabdomyolysis, and Acute Kidney Injury While Hiking in the Grand Canyon.

We present an unusual case of concomitant exercise-associated hyponatremic encephalopathy (EAHE), exertional rhabdomyolysis (ER), and acute kidney injury (AKI) in a Grand Canyon hiker. Our case patient, an adult 41-year-old male, consumed an excessive amount of water during his descent into the Canyon during hot weather. The next day, he was unable to hike out due to severe leg pain and disorientation, and ultimately evacuated by helicopter, having a grand mal seizure in flight. Despite having no serum sodium level, medics administered an intravenous (IV) bolus of 3% hypertonic saline (HTS) before transporting him to the hospital. There, he was diagnosed with EAHE (serum sodium, 114 mmol⋅L-1), ER, bilateral compartment syndromes, and mild AKI. The life-threatening EAHE was immediately corrected with more IV HTS, the limb-threatening compartment syndromes by surgical fasciotomies, and eventually, the AKI by oral and IV fluids. This case demonstrates the seriousness of overconsumption of water, as well as the potential complications of muscle damage when a deconditioned person does prolonged, strenuous exercise. Furthermore, it also illustrates the importance of considering EAHE within the differential diagnosis for acute alterations in level of consciousness. Lastly, it shows the importance to prioritize patient treatments for conditions that are an immediate threat to life or limb.

Cataracts Associated With Fibroblast Growth Factor Receptor Inhibitors for Cholangiocarcinoma

Since fibroblast growth factor receptor inhibitors (FGFRi) are used for treatment of intrahepatic cholangiocarcinoma (iCCA), understanding potential complications following longer-term use in clinical practice settings is warranted. This study describes cataract formation or progression as a complication of FGFRi use for the treatment of iCCA, even after treatment discontinuation. To describe cases of cataract formation or worsening in patients with iCCA treated with FGFRi and to characterize the ophthalmologic features, risk factors, and outcomes for FGFRi-associated cataracts. This retrospective case series study used data from patients with iCCA harboring FGFR2 aberrations who received FGFRi in clinical trials or as standard therapy from the University of California, San Francisco, Hepatobiliary Tissue Bank and Registry. Data were collected from patient visits between February 2015 and October 2021, and this retrospective investigation was conducted from September 6, 2022, to May 4, 2023. Data analysis was conducted from May 5, 2023, to September 6, 2023. Use of an FGFRi for the treatment of iCCA. The primary outcome was designated as development of a new or worsening cataract after FGFRi initiation. Statistical analysis for the association between cataract formation and clinical covariates was performed using unpaired t tests and Fisher exact tests. A single bivariate logistic regression model was used to examine total duration of FGFRi therapy and age at the conclusion of FGFRi therapy as predictors of cataract development. A total of 18 patients were included in the study; median (range) patient age was 54 (27-81) years, and 13 patients (72%) were female. Nine patients (50%) developed a cataract or had cataract progression in at least 1 eye after initiation of FGFRi. Of 17 eyes with cataract, 8 eyes (47%) required cataract surgery. One patient rapidly developed a cataract associated with phacomorphic glaucoma, which required urgent surgery. The median (range) time to cataract onset or worsening from initiation of FGFRi was approximately 18 (1-23) months. Five of 9 patients (56%) who developed cataracts or had cataract progression were diagnosed with new or worsening cataracts after discontinuation of FGFRi. Patients who developed cataracts had longer median (range) duration of FGFRi treatment compared with patients who did not develop cataracts (13 months [2-26] vs 5 months [1-11]; odds ratio, 1.01; 95% CI, 1.00-1.02; P = .02). While this retrospective case series study cannot prove cause and effect conclusively due to the study design, study results highlight cataract formation or progression as a potential adverse effect of FGFRi therapy, supporting consideration of periodic eye examinations in patients who have received this treatment.

Identifying Factors for Predicting Postoperative Segmental Motor Paralysis in Patients Undergoing Anterior Cervical Spine Surgery: A Multicenter Study.

Retrospective cohort study. To investigate the incidence of and risk factors for segmental motor paralysis after anterior cervical spine surgery. Segmental motor paralysis is a potential complication following both anterior and posterior cervical decompression procedures; however, previous studies investigating risk factors for segmental motor paralysis after anterior cervical spine surgery were limited by small sample sizes. Consequently, the exact pathogenesis and risk factors for this complication remain poorly understood, highlighting the need for larger-scale investigations focused exclusively on anterior cervical spine surgeries. We retrospectively reviewed the clinico-demographic and operative factors and postoperative outcomes of 1,428 patients undergoing anterior cervical spine surgery at three spine centers in Japan. Postoperative segmental motor paralysis was defined as deterioration of upper extremity muscle strength by ≥1 grade; recovery was defined as a return to preoperative muscle strength levels. Univariate and multivariate analyses were performed to identify risk factors. Ninety-nine patients (6.9%) developed segmental motor paralysis, mostly involving the C5 segment (81.8%), the incidence being highest in patients with ossification of the posterior longitudinal ligament (OPLL) and those undergoing anterior cervical corpectomy and fusion or hybrid fusion (discectomy + corpectomy). Older age, male sex, higher body mass index, OPLL, and cervical corpectomy were independent risk factors for paralysis, with these patients having significantly worse clinical outcomes at 1 year postoperatively. Most patients (74/99, 79.6%) regained preoperative muscle strength levels an final follow up. This study identified important clinico-demographic and operative risk factors for segmental motor paralysis after anterior cervical spine surgery. Patients undergoing corpectomy, with or without OPLL, were found to be at particularly high risk. While most patients recover well, worse outcomes with segmental motor paralysis highlight the importance of preventing this complication, particularly for OPLL patients and corpectomy procedures.

Pemphigoid Gestationis - literature review

Introduction and Objective: Pemphigoid gestationis (PG) is a rare, self-limiting autoimmune disorder, typically appearing in the second or third trimester of pregnancy. It can lead to postpartum exacerbations, and studies suggest an increased risk of preterm birth and the development of Graves' disease in the mother. The aim of this article is to gather the latest information on pemphigoid gestationis. Review Methods: A review of studies available in the PubMed database was conducted using the keywords "pemphigoid gestationis" and "dermatoses of pregnancy" in order to find publications from the last 8 years. Brief Description of the State of Knowledge: Pemphigoid gestationis (PG) is characterized by the production of IgG1 antibodies against bullous pemphigoid antigen 180 (BP180). The primary symptom of PG is intense itching, which often occurs before skin lesions develop. Diagnosis is typically confirmed through direct immunofluorescence (DIF) of perilesional skin. Treatment focuses on relieving itching and preventing new blister formation, usually starting with topical corticosteroids for mild cases, while systemic corticosteroids are reserved for more severe presentations. Recent research indicates that biologic therapies may also offer effective management options for PG. Summary: The authors highlight the need for further research due to the limited sample sizes in existing studies, as well as the potential complications during pregnancy and long-term health effects.

Assessing Chat Generative Pre-training Transformer’s Proficiency in Identifying, Diagnosing, and Managing Orthopedic Fractures

Abstract Background: The exploration of Chat generative pre-training transformer’s (GPT’s) applications in medicine is gaining momentum, with artificial intelligence, particularly ChatGPT, showing promise in enhancing orthopedic care. ChatGPT can assist clinicians by providing relevant information based on patient symptoms, medical history, and radiological findings, aiding in differential diagnosis, and suggesting appropriate imaging modalities. This study focuses on evaluating the effectiveness of ChatGPT-4 in diagnosing and managing common orthopedic fractures. Methods: This study involved inputting a diverse set of fracture images into the ChatGPT-4 model. The process commenced by prompting ChatGPT with four questions: “What does the radiograph show?” The second prompt instructed ChatGPT with the actual diagnosis, followed by inquiries on how a clinician should manage the condition and potential complications. All generated responses underwent grading by two authors (musculoskeletal radiologist and orthopedic trainee), utilizing a 5-point Likert scale. Intraclass correlation coefficient (ICC) analysis measurements were performed to assess inter-rater reliability. Descriptive statistical analysis was then employed to provide a comprehensive summary of the study’s findings. Results: ChatGPT demonstrated limitations in identifying diagnoses based on inputted X-ray images. However, it excelled in providing comprehensive information about fracture management and potential complications. There was excellent interobserver reliability with a kappa of 0.9. Conclusion: Our study underscores the utility of ChatGPT as a valuable tool for aiding in the management of common fractures, offering a comprehensive overview of diagnosis, management, and potential complications. The findings highlight its potential role as a supplementary resource in orthopedic practice.

Vaccinations in pulmonary diseases - part 2: herpes zoste, RSV, pneumococcal infection and pertussis

RSV is a common cause of respiratory tract infections, posing a risk of severe disease, particularly for newborns and infants, as well as in older individuals with pre-existing conditions. Two safe and effective RSV vaccines were approved in 2023. These vaccines elicit protective antibodies and offer robust protection with no additional benefit from annual boosters. Both vaccines have been approved for individuals aged 60 years and older, while one of the vaccines has also been approved in pregnant women to elicit maternal immunity for passive protection of the unborn child. In Germany, RSV vaccination is currently recommended for all individuals aged 75 years and older, as well as people aged 60-74 years of age with severe underlying conditions. PNEUMOCOCCAL INFECTION: Streptococcus pneumoniae is a primary cause of community-acquired pneumonia (CAP). Since early 2022, a 20-valent conjugate vaccine (PCV20) is approved and recommended for people over 60 years of age and individuals over 18 years of age with risk factors. PCV20 replaces the 23-valent polysaccharide vaccine (PPV23) previously recommended for those over 60 years of age. Although viewed primarily as a childhood disease, the majority of infections affect adults. Patients with chronic respiratory diseases are at a higher risk for severe clinical course of pertussis infection. It has therefore been recommended that all adults should get a pertussis booster with their next scheduled tetanus vaccination, given as a combination vaccine (Tdap). For risk groups (healthcare personnel, community facilities) a booster vaccination every 10 years is recommended. Herpes Zoster (shingles) is caused by the varicella-zoster virus, and reactivations can lead to painful skin lesions and potential complications such as herpes zoster oticus, meningitis, or postherpetic neuralgia. People with chronic lung diseases such as COPD or asthma are at increased risk of herpes zoster-related complications. A recombinant adjuvanted inactivated vaccine was approved in 2018 and offers robust protection against herpes zoster and its complications. The vaccine is recommended for all people over 60 years of age and for certain risk groups over 50 years of age.

Ultrasound visualization of Botulinum toxin injection: Identifying clinical correlates to optimize outcomes in spasticity management.

Botulinum toxin injections are well established and commonly used for spasticity management. Clinicians strive to optimize outcomes from toxin injections. One potential complication is toxin spread beyond the intended muscle, which can lead to unwanted weakness. The utilization of ultrasound allows direct visualization of target muscles and identification of toxin leakage from the target muscle. Ultrasound evaluation of clinical factors that correlate to toxin leakage have not been studied. To identify cases of botulinum toxin injectate leak beyond the targeted muscle during ultrasound-guided spasticity injections and associate cases of leak with predictive clinical factors, which include muscle size, fibroadipose changes, and number of previous injections. This was a prospective observational study. An outpatient clinic in an academic medical center. Patients who demonstrated wrist flexor spasticity warranting intervention were invited to participate. Patients received standard-of-care spasticity management with injection of onabotulinumtoxinA into the flexor carpi radialis muscle based upon clinical presentation and prescribing guidelines. Ultrasound video was recorded, and a blinded review was conducted by the study team. The primary outcome measure was visualized leak of injectate on recorded ultrasound video. Documented leak was then associated with clinical factors including diameter of the flexor carpi radialis, volume of injectate used, history of prior injections, and fibrotic change of the muscle. The study included 54 patients, 77.8% of whom had an underlying diagnosis of cerebrovascular accident. Injectate leak was observed in 18.5% of injections and could not be confirmed in 9.3% of injections. Multivariable analysis demonstrated increased odds of leak with higher Modified Heckmatt Scale score. No statistically significant increase in leak was noted with higher volume of injectate or smaller muscle diameter. Extramuscular leak of botulinum toxin injection may be associated with fibroadipose muscle change.

Association of fracture gap with implant failure in radius and ulna fractures in toy breed dogs-A multicenter retrospective cohort study.

To assess the impact of a postoperative fracture gap on implant failure following radius and ulna fracture repair in toy breed dogs. Retrospective multicenter cohort study. A total of 80 client-owned toy breed dogs. Medical records and radiographs were reviewed for dogs <3.5 kg that had surgical repair of simple transverse radius and ulna fractures at four institutions from 2005 to 2019. Data collected included signalment, fracture location, implant types and thickness, plate working length, evidence of a postoperative fracture gap in the caudal cortex, postoperative care, occurrence of implant failure, and other complications. The association between potential risk factors and complications was examined using multivariable logistic regression. A postoperative fracture gap in the caudal cortex was noted in 37 cases, and 10 cases experienced implant failure. Of the 43 cases without a gap, one case experienced implant failure. After adjusting for other variables, the fracture gap was significantly associated with implant failure (odds ratio = 23.0 [95% confidence interval: 2.7; 197.9], p = .004). Prolonged external coaptation was associated with minor and major complications other than implant failure (p = .04), while the absence of coaptation confounded the effects of the fracture gap on implant failure. Reduction of the caudal cortex of the radius is imperative to promote bone healing and prevent implant failure in transverse radius and ulna fractures of toy breed dogs.
