Abnormal neurodevelopmental outcomes are very likely in cases of bilateral neonatal arterial ischaemic stroke

AIM

Neonatal arterial ischaemic stroke (AIS) is an important cause of severe neurological disability. This study aimed to analyse the clinical manifestations and outcomes of AIS patients.

METHODS

We enrolled neonates with AIS admitted to Severance Children's Hospital and Gangnam Severance Hospital between 2008 and 2015. AIS was confirmed using magnetic resonance imaging (MRI). We retrospectively reviewed the clinical manifestations, MRI findings, electroencephalography (EEG) findings and neurodevelopmental outcomes.

RESULTS

The study comprised 29 neonates (18 boys). The mean follow-up period was 15.4 months (range 6-44 months), and the mean age at diagnosis was 8.1 days. Seizure was the most common symptom (66%). Bilateral involvement was more common than unilateral involvement (52%). The middle cerebral artery was the most commonly identified territory (79%). Abnormal EEG findings were noted in 93% of the cases. Neurodevelopment was normal in 11 (38%) patients, while cerebral palsy and delayed development were noted in eight (28%) and six (21%) patients, respectively. Patients with bilateral involvement were very likely to have abnormal neurodevelopmental outcomes.

CONCLUSION

Our study showed that abnormal neurodevelopmental outcomes were very likely after cases of neonatal AIS with bilateral involvement, and clinicians should consider early and more effective interventions in such cases.

Congenital Bimelic Hypertrophy of the Hands

Congenital hypertrophy of the hand is a rare phenomenon. The condition is characterized by hypertrophy of muscles, varies in severity and has been reported under different names. Some patients also have aberrant muscles. Electromyography is unremarkable, and the signal intensity on MRI and ultrasound is normal. The etiology is unknown and does not seem to be confined to a peripheral nerve, part of the plexus or nerve root. The condition is assumed to be congenital. We report a 28-year-old male with asymmetric hypertrophy of both hands and give a review of the 4 other cases known so far.

Clinical profile of 80-year-old and older thyroid eye disease patients

PURPOSE

Thyroid eye disease (TED), an autoimmune orbital disorder, follows a time-of-onset bimodal peak: 40-44 and 60-64 years for women, 45-49 and 65-69 years for men. TED, however, can also commence in old age. The study's purpose was to evaluate TED in octo- and nonagenarians.

METHODS

Medical records of 19 ≥ 80 years geriatric patients at time of diagnosis were compared to 122 TED patients, aged 20-79. A second analysis was performed after subdividing the control group into two age groups, ≤ 40 ("young group," 16 patients) and 41-79 years ("middle-aged group," 106 patients).

RESULTS

The geriatric group's mean age was 84 years (80-94), 11 males and 8 females. Mean follow-up time was 16 months. Compared to the controls, the geriatric patients smoked less (p = 0.012), were more often hypothyroid (p = 0.019), and had concurrent myasthenia gravis (p = 0.02) at time of diagnosis. Diplopia was the most common presenting symptom among the elderly (p = 0.005) and proptosis among the controls, specifically the young group (p = 0.027). Bilateral signs were more common among seniors (p = 0.049). Optic neuropathy was diagnosed in 10% of the geriatric group (2/19) and 11% of middle-aged group (12/106), all being resolved after steroids or orbital decompression. Active disease (clinical activity score (CAS) score =  > 3) was more common among the middle-aged group (p = 0.024) while the geriatric patients tended towards higher TED severity grades. Orbital decompression and eyelid repositioning surgeries were more common among the middle-aged group. Strabismus surgeries were more common among seniors.

CONCLUSIONS

TED among octo- and nonagenarians has unique patterns, with different demographic features, more exposed to diplopia, hypothyroidism, association with myasthenia gravis, and bilateral involvement. Special attention should be given when medically managing this subgroup.
