The frequency of acne appears to be increased in boys and men of the XYY genotype. This report describes severe acne in a retarded man in whom chromosomal analysis with differential banding suggested duplication of the distal portion of the long arm of a number 13 chromosome, a partial trisomy 13. In addition to retardation and seizures, his malformations, which included narrowed temples, ear anomalies, hexadactyly, and hernias, were consistent with those reported previously in patients with partial trisomy for the distal segment of chromosome 13. This patient and one recently reported retarded boy with chronic acne and trisomy 8 mosaicism suggest that the association of acne and chromosomal abnormality may not be limited to Y chromosome excess.

A case of complete trisomy 5p due to a de novo translocation t(2;5)(q36;p11) with an isochromosome 5p is described. Complete trisomy 5p has been reported only once (Brimblecombe et al., 1977). The confusing literature relating to partial trisomy 5p is reviewed. Comparison of our case with the patients reported by Brimblecombe et al. (1977) and by Opitz and Patau (1975) is suggestive for a distinct clinical syndrome if (almost) the complete short arm of chromosome 5 is present in a trisomic state. Unfortunately the clinical findings in the case of Brimblecombe (1966, 1977) are poorly documented. The main features of this syndrome are: macrocephaly, psychomotor retardation, hypotonia, postnatal growth failure, tracheobronchial involvement, mongoloid slant of the eyes, epicanthus, low-set ears, depressed nasal bridge, short first toe, and seizures.

In patients with the trisomy 13 syndrome the most commonly encountered brain anomaly is holoprosencephaly, which occurs in approximately 80% of cases. In trisomy 13 patients without holoprosencephaly, previously reported anomalies include callosal dysgenesis, hippocampal hypoplasia, olfactory hypoplasia, and cerebellar dysplastic changes such as vermian hypoplasia and dysplastic cortices. Dysplasia of the cerebral cortex, however, has not been reported before. We describe a newborn with bilateral, dysplastic cortices at the perisylvian and rolandic regions. These dysplastic cortices probably accounted for the clinical findings of seizures, oromotor dysfunction, dystonia flexion contractures in the hands, which were consistent with a recently described syndrome labelled as the "congenital bilateral perisylvian syndrome".

We retrospectively reviewed the medical records of neonates with chromosomal abnormalities and epilepsy who had been admitted to the neonatal intensive care unit (NICU) and followed up at the outpatient clinic of Dokkyo University School of Medicine. Chromosomal anomalies were diagnosed in 128 of 5789 patients admitted from 1978 through 2001. Seventy-one neonates had trisomy 21, 29 had trisomy 18, 8 had trisomy 13, and 20 had other chromosomal anomalies. Seizures occurred in five patients with trisomy 21 and in one patient each with trisomy 18, 6q-, 13q-, 21q-, and mosaicism trisomy 13. Two patients with 4p- [Wolf-Hirschhorn syndrome] were admitted to the NICU, but were not followed up at our outpatient clinic. The boy with 6q- (46,XY,-6, +der(6)t(6;11)(q25.1;q23.3)mat) had agenesis of the corpus callosum and multiple congenital anomalies as well as intractable epilepsy. The girl with 13q- (46, XX, t(2,4)(q24.2;p14), del (13)(q21.2q31.2)) had infantile spasms at 12 months, which were well controlled with nitrazepam and vitamin B6. The girl with mosaic trisomy 8q; (46, XX, der(8) (qter-->q11.2::p23.3-->qter)/46, XX), was not born at our hospital, but showed unique clinical features. She had intractable epilepsy characterized by episodes of vomiting and staring with astatic seizures. Computed tomography of the brain revealed bilateral calcification in the globus pallidus, associated with bursts of high-amplitude slow waves on electroencephalography. One of the two patients with del(15)(q12)[Angelman syndrome] had giant-amplitude visual evoked potential, suggesting hyperexcitability of the visual cortex.

In this report we describe a complication of a caudal block in a 4-year-old child with trisomy 13. The patient's history was remarkable for microcephaly, developmental delay, seizures, apnea, and prolonged emergence times. Induction of anesthesia and tracheal intubation were uneventful. A caudal block was aborted after positive aspiration of cerebrospinal fluid. A radiogram suggestive of spinal dysraphism, found on subsequent review, was confirmed by a magnetic resonance imaging scan consistent with tethered cord and dural ectasia. Congenital abnormalities associated with trisomy 13 and cutaneous signs suggestive of spinal abnormalities are reviewed. Avoidance of neuraxial regional anesthesia in these patients is recommended.

We describe a male carrier of trisomy 13 with scotosensitive and photosensitive myoclonic seizures appearing at the age of 8 months and persisting until death at 20 months. The seizures consisted of massive myoclonic jerks induced both by switching the room light suddenly on or off or by IPS with a frequency of 1 s. Spontaneous seizures were absent. The child also presented from the same age with breath-holding spells. This is interesting because it represents a rare example of the co-occurrence of scotosensitive and photosensitive seizures. Furthermore, a possible association to locus on 13q31.3 has been reported for photosensitivity, while for scotosensitivity there is no previous genetic information.

Acardia is a severe, complex malformation of monozygotic twinning, but beyond clinical case series, very few epidemiologic data are available. The goals of this study were to assess the epidemiologic characteristics of acardia from birth defect registries in the International Clearinghouse for Birth Defects Surveillance and Research (Clearinghouse), and compare these findings to current literature. The study included 17 surveillance programs of the Clearinghouse representing 23 countries from North and South America, Europe, China, and Australia. Anonymized individual records with clinical and demographic data were reviewed centrally by clinical geneticists. A literature search was performed. A total of 164 cases of acardia were reported from an underlying cohort of 21.2 million births. Of these, 23% were elective pregnancy terminations. Rates did not vary significantly by maternal age. For many cases, information on pregnancy exposures and genetic testing was missing. However, these limited data did not suggest high rates of chronic illnesses (diabetes, seizure disorders) or lifestyle factors such as smoking. One case had trisomy 13. Major malformations were reported in 2.4% of co-twins. With some basic assumptions, the total prevalence of acardia was estimated at 1 in 50,000-70,000 births, and 1 in 200-280 monozygotic twins. In summary, acardia is a dramatic, probably underreported, and incompletely understood malformation. Studies on its epidemiology and etiology are challenging and still rare. An international collaboration of epidemiologists, clinicians, and geneticists is necessary to understand the etiology, pathogenesis, and occurrence of this severe malformation complex.

Few cases of mosaicism involving a normal cell line and an unbalanced autosomal translocation have been reported so far. No cases of partial trisomy 13 and partial monosomy 8 mosaicism have been published. The authors report a new patient with partial trisomy 13 and partial monosomy 8 mosaicism due to an unbalanced translocation (13/8). A postzygotic mitotic exchange of nonhomologous chromatids followed by the loss of one of the translocated chromatids has been hypothesized as the potential underlying mechanism. Although a clear correlation of the clinical features of the patient with his chromosomal abnormality can be challenging, dysmorphic features, hyperactive behavior, moderate developmental delay, and tonic-clonic seizures can be interpreted as secondary to the particular genotype of the patient. These findings should be taken into account in the diagnostic process of patients presenting with multiple congenital anomalies and/or mental retardation conditions.

Congenital chromosomal abnormality with trisomy 13 is known to be associated with poor life prognosis and lethal. Therefore, physician advice the patients be kept in intensive treatment with resuscitation and state of the art intensive care when sudden change in the general condition with this trisomy is observed. We report herein, the treatment with mild brain hypothermia therapy for cardiopulmonary resuscitation after myoclonic seizures in infant with Robertsonian type of trisomy 13 in intensive care unit. Our study indicated that brain hypothermia therapy and steroid pulse therapy on an infant who was believed to have post-resuscitation hypoxic encephalopathy was highly effective as the patient's general condition recovered to the original state after four months.

Long term survival for the cases of trisomy 13 into over a first decade is very rare. We reported here the case of a 14-year-old male karyotype with full type of trisomy 13. In this clinical phenomenon, the case had typical facial, finger and limb anomalies for trisomy 13. Arterial septal defect and patent ductus arteriosus were recognized using ultrasonography after birth. Major cerebral malformation such as holoprosencephaly or cerebellar hypoplasia were also not revealed. After 5 months of his age, artificial ventilation therapy for dyspnea associated with laryngomalacia was required. A tracheotomy was performed at 6 months of his age. After 12 years old, intractable partial epilepsy was recognized. For his partial seizures, a treatment with a combination of two anti-epileptic drugs, valproic acid and levetiracetam, were advised. Now he is alive for 14-years-old and he is the 4th longest surviving patient with full karyotype of trisomy 13.
