Incomplete Kawasaki Disease with Peripheral Facial Nerve Palsy and Lung Nodules: A Case Report and Literature Review.

The diagnosis of Kawasaki disease (KD) is challenging and often delayed mainly in case of young infants and in presence of an incomplete disease and atypical features. Facial nerve palsy is one of the rare neurologic symptoms of KD, associated with a higher incidence of coronary arteries lesions and may be an indicator of a more severe disease. Here, we describe a case of lower motor neuron facial nerve palsy complicating KD and perform an extensive literature review to better characterize clinical features and treatment of patients with KD-associated facial nerve palsy. The patient was diagnosed at the sixth day of disease and presented extensive coronary artery lesions. A prompt treatment with intravenous immunoglobulins, aspirin and steroids obtained a good clinical and laboratory response, with resolution of facial nerve palsy and improvement of coronary lesions. The incidence of facial nerve palsy is 0.9-1.3%; it is often unilateral, transient, more frequent on the left and seemingly associated with coronary impairment. Our literature review showed coronary artery involvement in the majority of reported cases (27/35, 77%) of KD with facial nerve palsy. Unexplained facial nerve palsy in young children with a prolonged febrile illness should prompt consideration of echocardiography to exclude KD and start the appropriate treatment.

Pediatric Minimal Change Disease and AKI following the Pfizer-BioNTech COVID-19 Vaccine: causal or incidental correlation?

The global coronavirus 2019 (COVID-19) pandemic required vaccination even in children to reduce infection. We report on the development of acute kidney injury (AKI) and minimal change disease (MCD) nephrotic syndrome (NS), shortly after the first injection BNT162b2 COVID-19 vaccine (Pfizer-BioNTech). A 12-year-old previously healthy boy was referred to our hospital with complaints of peripheral edema and nephrotic range proteinuria. Nine days earlier he had received his first injection BNT162b2 COVID-19 vaccine (Pfizer-BioNTech). Seven days after injection, he developed leg edema, which rapidly progressed to anasarca with significant weight gain. On admission, serum creatinine was 1.3 mg/dL and 24-hour urinary protein excretion was 4 grams with fluid overload. As kidney function continued to decline over the next days, empirical steroid treatment and renal replacement therapy with ultrafiltration were started and kidney biopsy was performed. Seven days after steroid therapy, kidney function began to improve, gradually returning to normal. The association of MCD, nephrotic syndrome and AKI hasn't been previously described following the Pfizer-BioNTech COVID-19 vaccine in pediatric population, but this triad has been reported in adults. We need further similar case reports to establish the real incidence of this possible vaccine side effect.

A rare case of hydrometrocolpos from persistent urogenital sinus in patient affected by adrenogenital syndrome.

Persistent urogenital sinus (PUGS) is a congenital pathological condition characterized by an abnormal communication between the urethra and vagina, which has an estimated incidence of 0.6/10,000 female births. It could be the only known malformation or part of a syndrome. PUGS is commonly shown by a pelvic mass, related to a distended bladder, hydrometrocolpos which is due to an obstruction leading to the dilation of the vagina and uterus (i.e., imperforate hymen, transverse vaginal septum or atresia, and PUGS) or both. We present a case of female patient with classical congenital adrenal hyperplasia, diagnosed on the 7th day of life, with ambiguous genitalia, untreated surgically only with hormone therapy by parental decision. The patient, at the age of 5 years and 5 months, came to our observation for a pelvic ultrasound, which revealed retrovesical neoformation with anechoic content and regular walls. We performed the ultrasound examination that showed the dilation of the cervix and the vaginal canal with anechoic finely corpuscolated content in the declining portion, compatible with hydrometrocolpos from probable persistence of the urogenital sinus. The voiding cystourethrography (VCUG) confirmed the ultrasound diagnosis, with evidence of urogenital sinus. In conclusion, ultrasound is the first diagnostic tool, but need to be completed by other technical procedures, which VCUG or magnetic resonance imaging to observe the site of fusion of the urinary and genital tract.

A case of polimalformed fetus with a microdeletion of CTNNA3 gene.

We report a case of a male fetus of 20 weeks of gestation with plurimalformed observed by transonic scan and confirmed by MR. The karyotype was 46, XY. Molecular analysis showed a microdeletion of about 100 kb in the CTNNA3 gene.

Congenital megaurethra in a fetus with Meckel syndrome and in a fetus with female pseudoermanphroditism. The first report of these occurrences.

OBJECTIVE: the purpose of this paper is to report the first case of megaurethra in a fetus with Meckel syndrome and in a fetus with femal pseudoermaphroditism. RESULTS: the former case refers to a fetus of 13 weeks gestation with the three following prominent anomalies, observed by transonic scan and confirmed by autopsy: congenital megaurethra, anal atresia, single umbelical artery. The latter case refers to a fetus of 18 weeks gestation. Autopsy confirmed penile malformation and revealed ovaries in the abdomen. The karyotype was 46,XX with normal molecular karytype. The megaurethra was discovered by sonography at 18 weeks gestation. Autopsy confirmed penile malformation and revealed ovaries in the abdomen. The karyotype was 46,XX with normal molecular karyotype (Array-CGH, 1 Mb of resolution). METHODS: transonic scan, autopsy, karyotype, array-CGH. CONCLUSIONS: the first prenatal cases of two genetic syndromes with megaurethra have been reported, concening respectively a fetus with Meckel syndrome and a fetus with femal pseudoermaphroditism. The latter was confirmed by both autopsy and the normal female 46,XX karyotype.

Severe myopia with unusual retinal anomalies and Dandy-Walker sequence in two sibs. A distinct new neuro-ocular disorder.

We have observed a male and a female, sibs of non-consanguineous parents, affected by severe myopia with characteristic retinal defects and Dandy-Walker variant. The peculiarity of the retinopathy consists of pathological myopia with anomalous vitreal fenestrated membranes in the retinal periphery. We suppose that these associations may configure a new genetic syndrome.
