Background: Neonatal influenza is a rare condition. Young infants have immature immune defenses and are unable to receive direct vaccination; this can result in significant illness. Maternal anti-influenza immunization during pregnancy provides passive antibodies to the newborn via transplacental transfer, significantly decreasing the incidence and severity of influenza in early infancy. Nevertheless, the vaccination coverage during pregnancy remains low in many regions, leaving certain neonates without adequate protection. Methods: We present three cases of laboratory-confirmed influenza infection in neonates admitted to the “Sf. Ioan” Clinical Emergency Pediatric Hospital in Galați and conduct a literature review. The clinical presentation, co-infections, timing of antiviral therapy, laboratory findings, maternal vaccination status, and outcomes (including the hospitalization duration and recovery) were systematically analyzed for each case. Results: All three neonates were full-term and previously healthy, born to mothers who had not received influenza vaccinations during their pregnancies. They presented at ages ranging from 2 to 4 weeks with fever, respiratory symptoms including a cough, nasal congestion, and respiratory distress, as well as feeding difficulties. One case involved a co-infection with Bordetella pertussis, which manifested as a severe paroxysmal cough, cyanosis, and apnea. Laboratory findings in the cases with influenza alone indicated leukopenia accompanied by normal C-reactive protein levels. In the co-infection case, leukocytosis, lymphocytosis, and thrombocytosis were observed. All the infants received oseltamivir treatment within 48 h of the symptom onset; the case with pertussis co-infection also received azithromycin. Each infant required supplemental oxygen, but none necessitated mechanical ventilation. Clinical improvement was observed in all cases, with hospitalization ranging from 6 to 7 days and complete recovery without complications. Conclusions: Neonatal influenza may result in considerable morbidity, particularly in infants born to unvaccinated mothers. Positive outcomes, however, have been correlated with early diagnosis and antiviral treatment. Pertussis co-infection may exacerbate clinical progression, underscoring the importance of maternal immunization against both influenza and pertussis. In this case series, we aim to present three cases of laboratory-confirmed influenza in neonates born to mothers who were not immunized against influenza during pregnancy. These cases highlight the clinical presentations of neonatal influenza, underscore the risks associated with pertussis co-infection, and reinforce the importance of maternal influenza and Tdap vaccination for preventing severe outcomes in newborns.

Rare genetic movement disorders usually manifest early in life with dystonia, parkinsonism, chorea, or a combination thereof. These are often associated with neurodevelopmental delay, intellectual disability, speech problems, retinal abnormalities, seizures, ataxia, spasticity, or systemic features. Due to their vast number and pheno–genotypic heterogeneity, the diagnosis of these disorders can be challenging. However, recognising their core motor phenomenology as well as clinical, laboratory, and neuroradiological clues can expedite appropriate diagnostic workup, molecular diagnosis, and adequate treatment. In this review, we outline diagnostic clues to rare movement disorders (RMDs), focusing on those that present mainly with dystonia, parkinsonism, or paroxysmal dyskinesia due to genetic causes. Additionally, we provide a decision tree approach linking clinical, genetic, and imaging testing. Finally, we highlight selected RMDs that should not be missed, as they possess established treatments that can hinder their progression, prevent irreversible or life-threatening sequelae and, in certain cases, lead to complete symptom remission.

Background/Objectives: Parkinson’s disease (PD) and benign paroxysmal positional vertigo (BPPV) are both prevalent in the geriatric population. While dizziness is a common non-motor symptom in PD, the relationship between PD and incident BPPV remains unclear. Limited data suggest potential shared mechanisms, including mitochondrial dysfunction and oxidative stress, but large-scale epidemiological evidence is lacking. This investigation focused on assessing the incidence of BPPV in patients with PD compared to matched controls using a nationwide cohort. Methods: Data from the Korean National Health Insurance Service–Health Screening Cohort were used to perform a retrospective cohort analysis. We identified 8232 newly diagnosed PD patients and matched them 1:4 with 32,928 controls based on age, sex, income, and residential region. Stratified Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for incident BPPV. Subgroup and Kaplan–Meier analyses were also performed. Results: Over 220,151 person-years of follow-up revealed a lower incidence of BPPV in the PD group relative to the control group (4.98 vs. 5.95 per 1000 person-years); the corresponding adjusted HR was 0.77 (95% CI: 0.66–0.90; p = 0.001), indicating a 23% reduced risk. The inverse association remained consistent across most subgroups, including older adults and rural residents. Kaplan–Meier analysis further illustrated a significant decline in the cumulative incidence of BPPV in PD patients (p = 0.007). Conclusions: PD may contribute to a lower incidence of BPPV, which could be explained by reduced mobility, altered vestibular function, or diagnostic challenges. Clinicians should consider BPPV in PD patients presenting with dizziness. Full article

Background: Vestibular hypofunction occurs in 29.5% of older adults with benign paroxysmal positional vertigo (BPPV), but its impact on postural control, well-being and frailty was not studied before. This study compared the well-being, frailty and postural control between older adults with BPPV and vestibular hypofunction (oaBPPV+), and older adults with only BPPV (oaBPPV). Methods: Thirty-one older adults (≥65 years old) diagnosed with BPPV were recruited. Unilateral vestibular hypofunction was defined as a >25% caloric asymmetry, and bilateral vestibular hypofunction as a total response <6°/s per ear, using bithermal caloric irrigations. The oaBPPV+ group was compared to the oaBPPV group using the measures of well-being (Dizziness Handicap Inventory, Falls Efficacy Scale and 15-item Geriatric Depression Scale), frailty (Modified Fried Criteria), and postural control (timed chair stand test, mini-Balance Evaluation Systems test and Clinical Test of Sensory Interaction on Balance (CTSIB)). Falls and the number of repositioning maneuvers were documented. Significance level was set at α = 0.05. Results: Unilateral vestibular hypofunction was present in 32% of participants, mainly in females (p = 0.04). Bilateral vestibular hypofunction was not found. The oaBPPV+ group (n = 10, mean age 72.5 (4.5)) experienced more comorbidities (p = 0.02) than the oaBPPV group (n = 21, mean age 72.6 (4.9)). Groups did not differ regarding dizziness symptoms (p = 0.46), fear of falling (p = 0.44), depression (p = 0.48), falls (p = 0.08) or frailty (p = 0.36). However, the oaBPPV+ group showed significantly worse postural control under vestibular-dependent conditions (p < 0.001). Conclusions: Despite equally impaired well-being and frailty, the oaBPPV+ group showed greater sensory orientation deficits. Clinicians and researchers should be alert for co-existing vestibular hypofunction in older adults with BPPV, since this may exacerbate their already impaired postural control more than only BPPV.

Background/Objectives: The association between vestibular symptoms and psychological distress has been previously studied, mainly with the use of questionnaires. The purpose of this study is to compare the consumption of psychotropic drugs between a group of patients with vertigo and a control group. Methods: A prospective cross-sectional, observational, case–control study was carried out, including 506 patients (232 with Ménière’s disease, 79 with vestibular migraine, 34 with vestibular neuritis, and 161 with benign paroxysmal positional vertigo). In total, 253 participants were included in the control group. Both groups were comparable regarding age, sex, and history of previous psychiatric diseases. Results: The percentage of patients with vertigo who consumed psychotropic drugs (41.3%) was higher than the percentage of the control group who did so (26.9%) (Fisher’s exact test, p < 0.0001; OR = 1.914, CI95% (1.377; 2.662)). The mean number of psychotropic drugs consumed was also higher (Mann–Whitney test, p = 0.0003) in cases (0.68 ± 0.959) than in controls (0.47 ± 0.889). This higher consumption in the group of patients with vertigo was found for all pharmacological groups studied, being especially relevant regarding “anxiolytics and hypnotics and sedatives” and “antidepressants”. No statistically significant differences in the consumption of psychotropic drugs between types of vestibular disorders were observed. The longer the symptoms were present, the higher the prevalence of psychotropic drug use was observed. Conclusions: A relationship between vertigo and consumption of psychotropic drugs was found. Recording the consumption of these drugs is proposed as an objective method to better understand the psychological distress that patients with vertigo may suffer from. Full article

Background: Episodic ataxia type 2 (EA2) is a rare disorder characterized by paroxysmal gait instability, dysarthria, and dizziness. It is caused by CACNA1A mutations. Spinocerebellar ataxia type 6 (SCA6) rarely causes episodic ataxia-like symptoms. Acetazolamide has limited effectiveness for treating episodic ataxia. Methods: We investigated the effect of drug therapy in two patients with EA2 and one patient with SCA6 who presented with episodic ataxia. All three cases were CACNA1A-associated diseases. Results: In these three cases, acetazolamide administration was partially and transiently effective for episodic ataxia attacks. After levetiracetam addition, the number of ataxic attacks was significantly reduced, although the durations of attacks were not changed. The effect of levetiracetam was stable and continued for seven years. Levetiracetam and acetazolamide reduced chronic cerebellar ataxia in an SCA6 patient. Conclusions: In this small number of cases, levetiracetam was considered effective in two patients with EA2 and mildly effective in one patient with SCA6. Full article

Thromboembolism (TE) is a major cause of morbidity and mortality in patients with paroxysmal nocturnal hemoglobinuria (PNH). This narrative review summarizes available evidence on TE in Asian patients with PNH and discusses practical considerations and challenges for preventing and managing PNH-associated TE in Asian populations. Evidence suggests that, compared with non-Asians, fewer Asian patients have a history of TE (3.6% vs. 8.9%, p < 0.01), receive anticoagulants (8.5% vs. 16.2%, p = 0.002), or die from TE (6.9% vs. 43.7%, p = 0.000). Independent predictors of TE include lactate dehydrogenase ≥ 1.5 × upper limit of normal, pain, and male sex. Clone size alone does not appear to be a reliable estimate of TE risk. D-dimer levels are a useful marker of hemostatic activation, although they are not specific to PNH. Complement inhibition reduces the incidence of TE, although it does not wholly eliminate TE risk. Eligibility criteria and access to complement inhibitors vary across Asia, with limited availability in some countries. Anticoagulation is required to treat acute TE events and for primary or secondary prophylaxis in selected patients. Physicians and patients must stay alert to the signs and symptoms of TE to ensure prompt and appropriate treatment. Full article

Background and Clinical Significance: Sandifer syndrome is an uncommon manifestation of gastroesophageal reflux disease, characterized by paroxysmal episodes of abnormal posturing, particularly involving the neck and upper body, often associated with underlying esophageal discomfort. Case Presentation: In this report, we present a 16-month-old infant who exhibited multiple daily paroxysmal episodes of atypical head posturing, primarily tilted to the right, each lasting less than 10 s, with spontaneous resolution. Notably, these episodes lacked other neurological or systemic symptoms, and the clinical presentation differed from classical descriptions of Sandifer syndrome, which often include more prolonged dystonic posturing or correlation with feeding. The diagnosis was supported by the resolution of symptoms following the administration of a proton pump inhibitor, highlighting the importance of recognizing this condition in infants with unexplained posturing behaviors. Conclusions: This case emphasizes the variability in clinical manifestations of Sandifer syndrome and underscores the need for a high index of suspicion, as timely management of gastroesophageal reflux disease can lead to complete symptom resolution and prevent unnecessary neurological investigations.

Background: Heart failure (HF) is a progressive condition associated with reduced life expectancy and quality of life. Atrial fibrillation (AF), the most common arrhythmia in HF patients, significantly worsens symptoms and outcomes. The coexistence of HF and AF is linked to higher morbidity and mortality rates, with a bidirectional relationship exacerbating both conditions. The recent evidence has suggested that combining pulmonary vein isolation (PVI) with renal denervation (RDN) may offer a promising strategy for reducing AF burden and enhancing patient outcomes. Methods: This prospective interventional clinical trial aimed to assess the safety and effectiveness of a combined RDN and PVI approach compared to PVI alone. Eighteen patients, aged 18 to 80 years, with paroxysmal or persistent AF and HF (left ventricular ejection fraction [LVEF] < 50%) were enrolled. RDN was performed under general anesthesia using the four-electrode Symplicity Spyral catheter and Symplicity G3 radiofrequency generator (Medtronic). Patients were randomized to the RDN+PVI group (n = 7) or the PVI-only group (n = 11). The groups were similar in age (59 ± 8.4 years vs. 62.5 ± 11.08 years, p = NS) and baseline characteristics, including hypertension, obesity, and impaired left ventricular function (LVEF 35.86% vs. 38.54%, RDN+PVI vs. PVI only; p = NS). Results: Over a mean follow-up of 24 months, one patient died, ten were hospitalized, six underwent repeat PVI, and eight achieved AF freedom. Patients in the RDN+PVI group were significantly more likely to remain AF-free (n = 6 vs. 2; p = 0.0063). The need for repeat ablation was higher in the PVI-only group (54.5% vs. 0%), though this did not reach statistical significance. Hospitalization rates and changes in ejection fraction were similar between groups. Importantly, no procedural complications were observed. Conclusions: Combining RDN with PVI is a safe hybrid approach for AF management in HF patients, showing promising efficacy in reducing AF recurrence. Larger randomized studies are needed to confirm these findings and further explore this novel therapeutic strategy. Full article

Background/Objectives: Chronic pain is common following a stroke and is associated with increased disability. Yet, little is known about the chronic pain experience in the stroke population. This study aimed to identify and explore the features and neuropathic symptoms of chronic pain in individuals with longstanding stroke. Methods: This observational study utilized an online survey that was developed for individuals who have had a stroke (>3 months). Data sought included participant demographics, medical history, and details of the stroke(s). Participants who reported experiencing chronic pain completed the Numerical Rating Scale for Pain, the Neuropathic Pain Symptom Inventory, and body maps to indicate region(s) of pain. Results: A total of 533 individuals with longstanding stroke participated. Chronic pain was reported as being experienced by 60% of participants and was more frequently experienced by individuals who reported being female (p = 0.002). Moderate or severe pain intensity was commonly reported (mean = 5.98, SD = 1.89). Individuals with chronic pain post-stroke reported a range of neuropathic symptoms rather than a common pain experience, with combinations of spontaneous, paroxysmal, and evoked pains in addition to pain associated with paraesthesia/dysaesthesia. Pain involving the upper limb was the most common region (shoulder 39%, hand and forearm 38%), followed by the lower limb (foot 30%, leg 29%). Having multiple strokes was associated with a higher frequency of chronic pain (p = 0.01), as was peripheral vascular disease (p < 0.001) and lipid disorders (p = 0.001). Conclusions: These findings highlight the varied nature of chronic pain experienced by individuals following a stroke, while also detailing stroke and medical history associated with chronic pain. It builds on existing knowledge of chronic pain post-stroke and provides new insight into the neuropathic symptoms experienced. This knowledge has the potential to assist in the development of tailored interventions based on addressing pain symptomatology and health literacy. Full article

Background/Objectives: Functional seizures (FSs) are paroxysmal, time-limited events with motor, sensory, autonomic, or cognitive manifestations related to pathophysiological processes other than abnormal electric discharges in the brain. However, these seizures are often followed by different psychiatric comorbidities. Their impact on the overall quality of life and the cofounding factors, especially the ones that can be treated, were the main investigation aims of this study. Methods: This study comprised 76 patients who were diagnosed with FSs. This study included patients who were diagnosed with FSs via video-EEG telemetry. We used the “Likert scale” from the QOLIE 31 questionnaire to evaluate patients’ subjective perception of their quality of life. We researched the association of various clinical factors with the subjective QoL score. Results: A statistically significant marginal association was shown for seven variables, four of them with a positive association (subjective perception of disease severity, belief in treatments’ positive effects, functional seizure cessation, and not being afraid of next seizure) and three of them with a negative association (age at FS onset, depression symptoms, and current age of life). After Bonferroni correction for multiple testing only symptoms of depression stayed statistically significantly associated with outcome. Multivariable logistic regression following variable selection identified that six variables (age at FS onset, absence of psychiatric testing, perceiving oneself as mentally changed due to the disease, seizure severity, depressive symptoms, and fear of therapy side effects) were statistically significantly negatively associated with the outcome. Conclusions: It seems that patients who have FSs coexisting with depressive symptoms and also those with worse disease perception have less chances to be satisfied with their overall quality of life.

Background/Objectives: Benign Paroxysmal Positioning Vertigo (BPPV), diagnosed in 46% of older adults with complaints of dizziness, causes movement-related vertigo. This case-control study compared physical activity, frailty and subjective well-being between older adults with BPPV (oaBPPV) and controls. Methods: Thirty-seven oaBPPV (mean age 73.13 (4.8)) were compared to 22 matched controls (mean age 73.5 (4.5)). Physical activity was measured using the MOX accelerometer and the International Physical Activity Questionnaire. Modified Fried criteria assessed frailty. The Dizziness Handicap Inventory, Falls Efficacy Scale, and 15-item Geriatric Depression Scale assessed subjective well-being. A post-hoc sub-analysis compared all variables compared between frail oaBPPV, robust oaBPPV and robust controls. Significance level was set at α = 0.05. Results: oaBPPV were significantly less physically active and were more (pre-)frail (p < 0.001) compared to controls. They performed significantly less active bouts (p = 0.002) and more sedentary bouts (p = 0.002), and a significantly different pattern of physical activity during the day. OaBPPV reported significantly less time in transportation activities (p = 0.003), leisure (p < 0.001), walking (p < 0.001) and moderate-intensity activities (p = 0.004) compared to controls. Frail oaBPPV were even less active (p = 0.01) and experienced more fear of falling (p < 0.001) and feelings of depression (p < 0.001) than robust oaBPPV and controls. Conclusions: BPPV can induce a vicious cycle of fear of provoking symptoms, decreased physical activity, well-being and consequently frailty. It is also possible that frail and less physically active older adults have an increased prevalence of BPPV. Post-treatment follow-up should assess BPPV, frailty and physical activity to determine if further rehabilitation is needed. Full article

Background/Objectives: Pertussis remains a significant public health concern despite effective vaccines due to diagnostic challenges and symptom overlap with other respiratory infections. This study assesses the prevalence of Bordetella pertussis using advanced polymerase chain reaction (PCR) testing and examines the clinical outcomes over a one-month follow-up. Methods: We conducted a cross-sectional study at the University Hospital of Larissa, Greece, from April to June 2024, collecting 532 nasopharyngeal swabs from patients with respiratory symptoms. Diagnostic testing utilized the BioFire^® Respiratory 2.1 Plus Panel. Demographics, clinical presentations, vaccination histories, and clinical outcomes were systematically recorded and analyzed. Results: Of 532 patients, 47 (8.8%) were diagnosed with pertussis. The mean age was 61.87 ± 13.4 years; 57.4% were female. Only 12.8% had contact with known pertussis patients. Regarding vaccination history, 36.2% had received diphtheria, tetanus, and pertussis vaccines, with the last dose administered an average of 46 years prior to this study. The primary symptom was cough (100%), with additional symptoms including fever (36.2%) and paroxysmal cough (34%). Six patients (12.8%) required hospitalization due to pneumonia and severe respiratory failure. All patients received successful treatment; however, 23.4% reported persistent post-infectious cough at the one-month follow-up. Conclusions: PCR testing significantly improved the diagnosis of pertussis among adults presenting with respiratory symptoms. The findings highlight the need for updated vaccination strategies and improved diagnostic protocols to effectively manage pertussis and reduce its public health impact. Full article

Paroxysmal nocturnal hemoglobinuria (PNH) clones can be identified in a significant proportion of patients with aplastic anemia (AA). Screening for PNH clones at the time of an AA diagnosis is recommended by national and international guidelines. In this report, an expert panel of physicians discusses current best practices and provides recommendations for managing PNH in patients with AA in the Asia–Pacific region. Plasma/serum lactate dehydrogenase (LDH) levels and reticulocyte count should be measured with every blood test. PNH clone size should be monitored regularly by flow cytometry, with on-demand testing in the event of a rise in LDH level ± reticulocyte count or development of symptoms such as thrombosis. Monitoring for PNH clones can guide the choice of initial AA treatment, although flow cytometry has resource implications which may present a challenge in some Asia–Pacific countries. The treatment of patients with both PNH and AA depends on which condition predominates; following PNH treatment guidelines if hemolysis is the main symptom and AA treatment guidelines if bone marrow failure is severe (regardless of whether hemolysis is mild or moderate). The expert panel’s recommendations on the monitoring and treatment of PNH in patients with AA are practical for healthcare systems in the Asia–Pacific region. Full article

Background: Atrial fibrillation (AF) is prevalent among obese patients, and cryoballoon ablation (CBA) is an effective strategy for the rhythm control of AF. The impact of body mass index (BMI) on the clinical outcomes of CBA for AF is not fully explored. Methods: 85 consecutive patients with paroxysmal AF were enrolled and were categorized into three groups as per their BMI: normal weight (BMI 18.5–25 kg/m²), overweight (BMI 25–30 kg/m²), and obese patients (BMI > 30 kg/m²). The primary study endpoint was a late (12 month) recurrence of AF. Early recurrence of AF, symptom improvement, and procedural outcomes were some key secondary outcomes. Results: 20 patients had normal weight, 35 were overweight, and 30 were obese. Obese patients featured a higher prevalence of diabetes mellitus, heavier exposure to smoking, and worse baseline symptoms (as assessed through EHRA class at admission and 12 months before CBA) compared to overweight and normal weight patients. Both late and early (<3 months) AF recurrence rates were comparable across the three groups. Of note, obese patients showed greater improvement in their symptoms post-CBA, defined as improvement by at least one EHRA class, compared to normal weight patients; this might be explained by improved diastolic function. Total procedure time and dose area product were significantly increased in obese patients. The multivariate logistic regression analysis indicated that early AF recurrence and the duration of hypertension are independent predictors of late AF recurrence. Conclusion: CBA is effective in overweight and obese patients with paroxysmal AF. Procedure time and radiation exposure are increased in obese patients undergoing CBA. Full article
