Ischemic stroke in children in course of moyamoya disease : case report
Background: Progressive stenosis of the supraclinoid segments of the internal carotid arteries, followed by formation of characteristic collateral brain circulation is typical for moyamoya disease. This illness, with unknown pathogenesis, is often diagnosed in Asiatic population. In Poland it can be a rare cause of ischemic infarcts in children. Case report: Two cases of cerebral ischemic infarct due to moyamoya disease in girls aged 7 and 12 are presented. The final diagnosis was established after MR exams and digital subtraction angiography (DSA) of the cerebral arteries. Conclusions: In spite of rare incidence, the moyamoya disease should be considered as the potential cause of cerebral ischemic infarctions in children. Despite the main role of the DSA in establishment of the final diagnosis, noninvasive neuroradiological examinations become more and more important in diagnostic schedule of moyamoya disease. MR and MR angiography visualize characteristic radiological symptoms, enabling preliminary diagnosis and are the method of choice in control examinations
Nieprawidłowości ortopedyczne u 8-letniej pacjentki z chorobą Sanfilippo A: opis przypadku
Sanfilippo syndrome (mucopolysaccharidosis III – MPS III) is a rare genetic disease characterised by progressive neurodegeneration caused by uncontrolled lisosomal and intercellular space glycosaminoglycans (GAGs) accumulation. The disorder occurs after several years of proper child development and is related to changes in nervous, gastrointestinal, cardiovascular, respiratory, visual, auditory and musculoskeletal systems. The authors present orthopaedic abnormalities in an 8-year-old patient with Sanfilippo disease and discuss recommendation for medical intervention of skeletal deformations in patients suffering from Sanfilippo disease. Case presentation: an 8-year-old girl with Sanfilippo disease is reported on. She was diagnosed at the age of 3 when the first abnormalities were revealed. At the age of 8, when orthopaedic problems occurred the physical examination presented characteristic features of MPS such as thickened facial lines, flat base of the nose and dry, light hair. In neurological examination she presented macrocephaly, decreased axial muscle tone and increased circumferential muscle tone, independent but impaired gait pattern. Orthopaedics examination and diagnostic procedures revealed coxa vara, knee valgum and Achilles tendon contraction. Conclusion: Sanfilippo syndrome is a rare genetic – autosomal recessive – disease belonging to the group of Lysosomal Storage Disorders (LSDs). After several years after the first symptoms of the disease abnormalities in musculoskeletal system are revealed. The most common orthopaedic procedures in these patients are carpal tunnel release, trigger-finger release and hip replacement. In each case the patient`s QoL and the high risk of surgery and anaesthesia should be balanced individually.Choroba Sanfilippo A (mukopolisacharydoza III A) jest rzadką chorobą genetyczną charakteryzującą się postępującą neurodegeneracją spowodowaną wrodzonym niedoborem sulfatazy heparanu prowadzącym do niekontrolowanej akumulacji glikozaminoglikanów (siarczanu heparanu) w przestrzeni lizosomalnej i międzykomórkowej. Zaburzenie pojawia się po kilku latach prawidłowego rozwoju dziecka i jest związane ze zmianami w układzie nerwowym, żołądkowo-jelitowym, sercowo-naczyniowym, oddechowym, wzrokowym, słuchowym i mięśniowo-szkieletowym. Autorzy przedstawiają nieprawidłowości ortopedyczne u 8-letniej pacjentki z chorobą Sanfilippo A i omawiają rekomendacje dotyczące ortopedycznego leczenia deformacji szkieletowych w tej jednostce chorobowej. Prezentacja przypadku: Autorzy opisują 8-letnią dziewczynkę z chorobą Sanfilippo A, u której w wieku 3 lat ujawniły się pierwsze symptomy choroby. W wieku 8 lat, kiedy zaczęły się objawy ortopedyczne, w badaniu fizykalnym stwierdzano charakterystyczne dla mukopolisacharydozy cechy t.j.: pogrubiałe rysy twarzy, płaską nasadę nosa i suche, jasne włosy. W badaniu neurologicznym pacjentka prezentowała wielkogłowie, obniżone napięcie w osi głowa-tułów, a wzmożone w kończynach, chód samodzielny w nieprawidłowym wzorcu. Badanie ortopedyczne i badania dodatkowe ujawniły szpotawość stawów biodrowych, koślawość stawów kolanowych oraz tendencję do przykurczu ścięgien Achillesa. Wnioski: Choroba Sanfilippo A jest rzadką chorobą genetyczną – autosomalną recesywną – należącą do grupy lizosomalnych chorób spichrzeniowych. Po kilku latach od pierwszych objawów choroby ujawniają się nieprawidłowości w układzie mięśniowo-szkieletowym. Najczęstsze zabiegi ortopedyczne w tej grupie pacjentów to uwolnienie cieśni nadgarstka i endoprotezowanie stawu biodrowego. W każdym przypadku należy indywidualnie rozważyć korzyści przekładające się na jakość życia chorego biorąc pod uwagę wysokie czynniki ryzyka podejmowanych interwencji operacyjnych i znieczulenia
Dramatic Course of Paediatric Cryptogenic Febrile Infection-Related Epilepsy Syndrome with Unusual Chronic Phase Presentation—A Case Report with Literature Study
Febrile Infection-Related Epilepsy Syndrome (FIRES) is a catastrophic, extremely rare epileptic encephalopathy. It strikes previously healthy school-aged children and is usually cryptogenic. Its dramatic onset with refractory status epilepticus is always preceded by a nonspecific febrile illness. The seizure activity in FIRES may last for several weeks with little to no response to antiepileptic treatment, usually resulting in the usage of anaesthetics. This acute phase is followed by a chronic, refractory epilepsy and cognitive deficit, that persist for the rest of the patient’s life. Still to this day no definite cause has been described. In this study we review the current finding in FIRES and describe a case of a 4-year-old patient with a dramatic course of the acute phase in FIRES and unusual presentation of the chronic phase, which is dominated by extrapyramidal symptoms such as dystonia. This case highlights that the clinical presentation of FIRES may differ from those frequently described in literature
Multiple sclerosis in children – clinical aspects and diagnostic dilemmas
Wstęp. Stwardnienie rozsiane (SM) jest przewlekłą, nabytą
chorobą demielinizacyjną ośrodkowego układu nerwowego.
Patogeneza choroby nadal pozostaje nieznana, chociaż modele
eksperymentalne dostarczają dowodów na temat podłoża zapalno-
demielinizacyjnego. Szacowana częstość występowania
SM wynosi 3.6 przypadków na 100 000 osobolat wśród kobiet
oraz 2.0 u mężczyzn. Około 10% chorych doświadcza pierwszych
objawów przed 18. rokiem życia. Diagnoza SM u osób dorosłych
opiera się na kryteriach McDonalda, które obejmują objawy
kliniczne, ocenę zmian w badaniach neuroobrazowych (MR
głowy i rdzenia kręgowego), obecność prążków oligoklonalnych
w płynie mózgowo-rdzeniowym oraz nieprawidłowe potencjały
wywołane. Te kryteria są mniej przydatne w populacji dziecięcej,
we wczesnych stadiach choroby. Postawienie prawidłowej diagnozy
u młodszych pacjentów stanowi problem diagnostyczny,
ponieważ objawy kliniczne mogą sugerować inną chorobę
zapalno-demielinizacyjną lub neurometaboliczną.
Cel pracy. Celem pracy była retrospektywna analiza obrazu
klinicznego oraz wyników badań dodatkowych u dzieci z rozpoznanym stwardnieniem rozsianym w odniesieniu do
aktualnie obowiązujących kryteriów.
Materiał i metody. Grupę badaną stanowiło 29 dzieci w wieku
od 5 do 17 lat (wiek średni: 15lat) hospitalizowanych w Klinice
Pediatrii i Neurologii Wieku Rozwojowego SUM w Katowicach
w latach 2005–2010.
Wyniki. U wszystkich dzieci rozpoznano postać rzutowo-remisyjną
stwardnienia rozsianego. Najczęściej występującymi
pierwszymi objawami były zaburzenia ruchowe i czuciowe
(52%). U 91% dzieci stwierdzono obecność prążków oligoklonalnych.
58% pacjentów spełniało kryteria McDonalda
z 2005 r., 90% – kryteria McDonalda z 2010 r., natomiast
17%pacjentów 3 z 4 kryteriów Barkhofa.Background. Multiple sclerosis (MS) is a chronic, acquired
demyelinating disease affecting central nervous system.
The pathogenesis of the disorder is still unclear, although
experimental models provide evidences of autoimmune and
inflammatory basis of the disease. The estimated occurence
of MS is 3.6 cases per 100,000 person-years in women and
2.0 in men. Up to 10% of patients experiences their first
symptoms before the age of 18. The diagnosis of MS in adults
is based on Mc Donald criteria, that include clinical symptoms,
magnetic resonance imaging (MRI) of the brain and spinal
cord, the presence of oligoclonal bands in cerebrospinal fluid
(CSF) and abnormal visual evoked potentials. These criteria
are less useful in early stages of the disease in children. The
exact diagnosis in young patients is even more difficult
because of clinical presentation which may suggest other
inflammatory-demyelinating and neurometabolic diseases.
Aim. The authors analyze a group of 29 children (clinical
presentation and additional examinations) in reference to
current diagnostic criteria. Material and methods. The analyzed group consisted of
27 children hospitalized in Child Neurology Department of
Medical University of Silesia in Katowice in the years 2005-
2010. The average age at diagnosis was 15 years, the range
was 5 to 17 years.
Results. All children exhibited relapsing, remitting multiple
sclerosis. In the analyzed group, patients presented with
initial symptoms concerning predominantly sensory and
motor symptoms - 52 %. The oligoclonal bands were present
in 91% of examined children. 58% of patients fulfill the 2005
McDonald criteria, revised 2010 McDonald criteria 90%.
17 children presented three out of four Barkhof magnetic
resonance imaging criteria

Nusinersen treatment of Spinal Muscular Atrophy Type 1 — results of expanded access programme in Poland
Aim of the study. This study aimed to evaluate the effects of nusinersen therapy in Polish children with SMA type 1. Clinical rationale of study. Spinal muscular atrophy (SMA) is a neuromuscular disorder that is characterised by the loss of motor neurons, progressive muscle weakness and atrophy, leading to increased disability and mortality. Nusinersen, an antisense oligonucleotide that promotes production of the functional survival motor neuron protein is approved for the treatment of SMA 5q in the European Union. In 2017, an early access programme (EAP) for nusinersen was launched in Poland. In this study, we present the results of nusinersen treatment in Polish patients participating in the EAP. Materials and methods. We collected prospectively clinical data including mutational analysis of SMN1 and SMN2 genes, motor function outcomes as measured on a standardized scales, ventilatory and nutritional status, on SMA type 1 patients receiving nusinersen in three EAP centres in Poland. Scores on the CHOP-INTEND scale after 18–26 months of treatment were compared to baseline. Results. We analysed data from 26 patients with SMA type 1, mean age 4.79 (2–15) years. The mutational analysis revealed two SMN2 gene copies in the majority of patients (61.54%). Three and four copies were found in 34.62% and 3.84%, respectively. Median disease duration was 21 months. Half (n = 13) of the patients required mechanical ventilation at baseline and 57.69% (n = 15) were fed by nasogastric tube or percutaneous endoscopic gastrostomy. No patient worsened during the follow-up. Mean improvement in CHOP-INTEND from baseline to the last follow-up was 7.38 points (p < 0.001). CHOP-INTEND scores did not decline for any patient. Patients with three or more SMN2 gene copies had higher scores than did the patients with two copies (p = 0.013), and they tended to show greater improvement over time, but the difference was not significant (p = 0.324). Shorter disease duration and higher CHOP-INTEND baseline score were associated with a better response (p = 0.015). Patients with a CHOP-INTEND score above the median had higher scores overall than the rest (p < 0.0013), and they improved significantly more than the rest (p = 0.037). Nusinersen was well tolerated, no new safety findings were identified. Conclusions and clinical implications. Our data indicates that nusinersen treatment might be effective in SMA type 1 patients, regardless of their age and functional status
Safety, tolerability, and efficacy of a widely available nusinersen program for Polish children with spinal muscular atrophy
Pediatric-onset multiple sclerosis in Poland : a registry-based retrospective cohort study
The clinical and epidemiological profile of paediatric-onset multiple sclerosis in Poland
Background. Paediatric-onset MS (POMS) has a unique clinical profile compared to the more prevalent adult-onset MS. For this study, we aimed to determine the demographic and clinical characteristics of POMS in Poland as well as addressing some of its epidemiological aspects. Methods. A retrospective study was conducted based on the Polish Multiple Sclerosis Registry, considering a population of children and adolescents with MS (age ≤ 18 years). Data were collected by all 13 centres across Poland specializing in diagnosing and treating POMS. The actual course of the disease and its clinical properties were compared between child (≤12 years) and juvenile (>12 years) patients. MS onset and its prevalence were assessed at the end of 2019, stratified by age range. Results. A total of 329 paediatric or juvenile patients (228 girls, 101 boys) with a clinically definite diagnosis of MS, in conformity with the 2017 McDonald Criteria, were enrolled. For 71 children (21.6%), the first symptoms appeared before the age of 12. The female: male ratio increased with age, amounting to 1:1 in the ≤12 years group and to 2.9:1 in the >12 years group. In most cases, the disease had multi-symptomatic onset (31.3%), and its course was mostly of a relapsing–remitting character (95.7%). The initial Expanded Disability Status Score for both groups was 1.63 ± 1.1, whereas the annual relapse rate was 0.84 during the first 2 years. The time between the onset of symptoms and diagnosis was longer in the younger patients (8.2 ± 4.2 vs. 4.6 ± 3.6 months; p < 0.005). On 31 December 2019, the age-adjusted prevalence standardized to the European standard population was 5.19/100,000 (95% CI, 4.64–5.78). Significantly higher prevalence was noted in the 13–18 years group (7.12; 95% CI, 6.64–7.86) than in the 9–12 years group (3.41; 95% CI, 2.98–3.86) and the <9 years group (0.56; 95% CI, 0.46–0.64; p < 0.001). Conclusion. POMS commencing at the age of ≤12 years is rare, differing significantly from the juvenile-onset and adult MS in terms of clinical characteristics, course, and incidence, as stratified by gender
