Abstract Background During the global H1N1 pandemic, neurological complications were reported in approximately 6–10% of children suffering from H1N1 infection, but only rarely in adults. Generalized convulsive status epilepticus (GCSE) as a presenting manifestation of H1N1 infection in an adult is exceedingly rare and has not been reported in literature. We report a patient who presented to us with GCSE as a presenting manifestation of H1N1 infection who improved following appropriate antiviral treatment. Methods and results This 20-year-old gentleman presented to us with history of fever followed by GCSE of 24 h duration. He was treated symptomatically and was evaluated in detail. He was diagnosed to be suffering from H1N1 infection based on appropriate serological tests. After start of antiviral therapy, he improved and is doing well at 4 months follow up. Conclusion This case report further expands the spectrum of clinical findings associated with sporadic H1N1 infection. A possibility of H1N1 infection should be considered in all patients who present with GCSE without any obvious cause so that appropriate diagnostic tests and treatment can be carried out at the earliest.

Neurological complications of COVID-19 are well documented. However, there are limited reports of posterior reversible encephalopathy syndrome (PRES) associated with COVID-19 in the literature. Herein, we described a 21-year-old man with a history of bipolar disease and opioid addiction who was admitted because of COVID-19 infection. He suddenly experienced a convulsive status epilepticus following hypertension crisis. The patient was intubated and underwent antiepileptic and anti-hypertensive therapy. His brain imaging was compatible with PRES. The patient gradually improved and was eventually discharged after 40 days. On the next month follow-up, the patient was able to walk with a cane without a history of seizure. In this report, we aimed to highlight the less common cerebrovascular complication of COVID-19 infection.

Orolabial Herpes

Herpes esophagitis (HE) is a rare condition in immunocompetent adolescents. However, it commonly occurs as a primary infection in younger individuals. Herein, we report a 16-year-old female patient who had a history of fever for 5 days, odynophagia, and orolabial herpes infection for 7 days. Clusters of painful vesicles on an erythematous base on the lips, gingiva, and palate were observed on physical examination. Further, esophagogastroduodenoscopy revealed diffuse linear ulcerations in the distal esophagus. The patient then received the following treatment: intravenous (I.V.) acyclovir 5 mg/kg three times a day, I.V. omeprazole 40 mg two times a day, and acyclovir 5% cream four times a day. After 8 days of admission, the patient was discharged. A follow-up esophagogastroduodenoscopy was performed 7 weeks after discharge, and the results revealed that the esophageal mucosa had a normal appearance. The effect of antiviral treatment against HE remains unknown in these patients. Nevertheless, it is believed to accelerate the healing process in individuals with esophageal mucosal barrier damage. To the best of our knowledge, this case of a female adolescent with an intact immune system is the sixth case of herpes simplex esophagitis to be reported in the literature.

Background: Dalfampridine extended release (DAL) is a broad-spectrum voltage-gated potassium channel blocker that is indicated in multiple sclerosis to improve the nerve conduction of demyelinated axons. Seizures are a known side effect of DAL, which is contraindicated in patients with a history of epilepsy. Objective: Three cases of multiple sclerosis (MS) with de novo convulsive status epilepticus (CSE) probably related to dalfampridine administration are described. Methods: No patients had a history of seizures or renal impairment. Biological tests were normal. A brain magnetic resonance imaging (MRI) showed diffuse cortical and subcortical atrophy without active inflammatory lesions. Results: All three patients presented with CSE that was attributed to DAL and so was discontinued. Conclusion: These case reports illustrate that, aside from seizures, de novo CSE is a potential complication of MS patients treated with DAL.

The effects of status epilepticus on the orexin/hypocretin system have yet to be investigated. The present study aimed to assay orexin-A/hypocretin-1 in the cerebrospinal fluid (CSF) of patients after generalized convulsive status epilepticus (GCSE). The study groups included 20 GCSE patients, 24 patients diagnosed with epilepsy but remaining in remission (ER), and 25 normal controls (CTR). Diagnostic lumbar puncture was performed in GCSE patients within 3–10 days of seizure cessation, as well as in the ER and to CTR subjects. Among all GCSE patients, the outcome was graded according to the modified Rankin Scale (mRS) at 1-month follow-up. Orexin-A levels were measured in unextracted CSF samples, using a commercial radioimmunoassay. There was a significant overall difference in median CSF orexin-A concentrations between GCSE, RE, and CTR patients (p < 0.001). The lowest concentrations were noted in the GCSE group compared to ER (p < 0.001) or CTR (p < 0.001). CSF orexin-A levels in GCSE patients inversely correlated with clinical outcome as assessed on the mRS at 1-month follow-up (r = −0.55; p = 0.1). In conclusion, CSF orexin-A levels may serve as a biomarker of increased turn-over of the peptide or post-SE neuronal damage, and implicates the orexin system in the pathogenesis of SE.

Case summary A 10-year-old male neutered domestic shorthair cat was presented with a 4 month history of slow, progressive swelling and intermittent multifocal bleeding of the distal right forepaw that progressively developed after cephalic vein catheterisation for anaesthesia. The procedure was performed for dental calculus removal. Initial clinical and biopsy (superficial biopsy) findings matched two differential diagnoses: progressive angiomatosis and acquired peripheral arteriovenous fistula (AVF). AVF was suspected based on Doppler ultrasound examination that identified multiple abnormal sinusoidal neoformed branching vessels with turbulent high-velocity flow spectrum at the confluence of the artery and vein, and high-velocity arterialised flow in the vein. Owing to rapid and severe progression of lesions after biopsy, the owner requested amputation of the cat’s limb. A definitive diagnosis of acquired iatrogenic peripheral AVF was based on deep-tissue microscopical evaluation. High numbers of arterioles and venules in superficial and deep dermis embedded in oedematous stroma were connected to dilated and tortuous vessels with irregularly thickened walls in deep dermis and panniculus. Vasculitis and vascular thrombosis and thickening (attributed to local hypertension) were common findings. No bone or muscular invasion were observed. The cat was doing well 3 years after surgery. Relevance and novel information This report describes a case of iatrogenic acquired peripheral AVF following venous catheterisation in a cat, fully documented for the first time by a combination of clinical findings, ultrasound imaging, complete histopathology and follow-up history.

Abstract Objective The impact of the M184V/I mutation on the virological failure (VF) rate in HIV-positive patients with suppressed viremia switching to an abacavir/lamivudine/dolutegravir regimen has been poorly evaluated. Method This is an observational study from 5 European HIV cohorts among treatment-experienced adults with ≤50 copies/mL of HIV-1 RNA who switched to abacavir/lamivudine/dolutegravir. Primary outcome was the time to first VF (2 consecutive HIV-1 RNA &gt;50 copies/mL or single HIV-1 RNA &gt;50 copies/mL accompanied by change in antiretroviral therapy [ART]). We also analyzed a composite outcome considering the presence of VF and/or virological blips. We report also the results of an inverse probability weighting analysis on a restricted population with a prior history of VF on any ART regimen to calculate statistics standardized to the disparate sampling population. Results We included 1626 patients (median follow-up, 288.5 days; interquartile range, 154–441). Patients with a genotypically documented M184V/I mutation (n = 137) had a lower CD4 nadir and a longer history of antiviral treatment. The incidence of VF was 29.8 cases (11.2–79.4) per 1000 person-years in those with a previously documented M184V/I, and 13.6 cases (8.4–21.8) in patients without documented M184V/I. Propensity score weighting in a restricted population (n = 580) showed that M184V/I was not associated with VF or the composite endpoint (hazard ratio [HR], 1.27; 95% confidence interval [CI], 0.35–4.59 and HR 1.66; 95% CI, 0.81–3.43, respectively). Conclusions In ART-experienced patients switching to an abacavir/lamivudine/dolutegravir treatment, we observed few VFs and found no evidence for an impact of previously-acquired M184V/I mutation on this outcome. Additional analyses are required to demonstrate whether these findings will remain robust during a longer follow-up.

Abstract Sickle cell anemia (SCA) may cause a variety of neurological complications, including stroke and headaches. Stroke occurs in up to 9% of children with SCA, and transcranial Doppler (TCD) studies have demonstrated that increased velocities are related to higher stroke risk. Throbbing headache occurs in SCA but its cause, frequency, and relationship to TCD velocities have received little attention. On the other hand, there are few TCD studies in adult patients. Our aims were: 1) to describe the main features of TCD in adult SCA patients, and 2) to investigate if there were correlation between TCD features and presence of headache. TCD was performed in 56 adult SCA patients (≥ 16 years old) and in 56 healthy individuals (HI), matched by age and race. There were 6 patients with a remote history of stroke but none were on chronic transfusion. The SCA group was submitted to a neurological evaluation and specifically asked about the occurrence of headache and its characteristics. The highest flow velocity (maxFV) recorded for each artery was considered the most representative. We analyzed the frequency of FV asymmetry (side-to-side difference > 20%) and focal FV changes. The mean maxFV was significantly higher in patients (117.7 ± 21.6 cm/s) than in HI (72.45 ± 11.48 cm/s) (p<0.005). Only one patient had maxFV higher than 170 cm/s. The frequencies of asymmetry and of focal FV changes were significantly higher in SCA. Forty-one patients (73.2%) reported having headaches. Twenty-eight patients (50%) had severe (= 5 for pain intensity at a 1–10 scale) and frequent headaches (at least once a month). This group of patients presented TCD velocities significantly higher than patients without or with milder headaches (p=0.035). In conclusion, TCD maxFV was significantly higher in adult patients with SCA than HI, however, only one patient was considered at risk of stroke according to TCD criteria described in children. FV asymmetry and focal FV changes may be markers for arterial disease in adult SCA patients, and need to be further confirmed by neuroimaging and clinical follow up studies. The patients with severe headaches presented TCD velocities significantly higher than patients without or with milder headaches, but this finding needs to be confirmed by more and larger studies.

Clonic Seizures

The electroclinical features of two Thai women with ring chromosome 20 and nonconvulsive status epilepticus (NCSE) were studied. Both have also had generalized tonic-clonic seizures and complex partial seizures of varying frequencies since adolescence. Their intellectual functions were normal. Twenty-four-hour video/EEG telemetry recorded during the NCSE showed fluctuating consciousness between overt unresponsiveness and normal awareness. The EEG consisted of long-lasting generalized rhythmic 3–5 Hz sharp or slow waves with a few spikes, lasting several days. Despite the continuous discharges, the patients had relatively subtle clinical episodes of seizures, during which they were sometimes responsive to verbal stimuli. Intravenous antiepileptic drugs (AED) had little effect on the rhythmic EEG. No lesion in their MRIs contributed to NCSE. Ring chromosome 20 was found in 20% of female karyotype in both patients [46,XX, r(20) (p13 q13)/46,XX] but were negative in four healthy siblings. Oral AEDs decreased more than 75% of the overt CPS episodes in both patients at 22 and 26 months of follow-up but had no effect on the natural history of electrical NCSE. The patients' daily activities were minimally affected by the ongoing electrical discharges. These are the first two cases reported of ring chromosome 20 with NCSE in Thailand. Our patients present a rather benign and pharmacologically responsive course probably because of the low percentage of r(20) mosaicism. The electroclinical correlations in our cases raise the possibility that the mechanism of continuous rhythmic waves in this syndrome may be unrelated to epilepsy. Assessing the severity of this syndrome using both clinical seizures and EEG is crucial.
