An infant with karyotype 46,XY,der(8),t(3;8)(q21;p23) is presented. The presence of trisomy 3q21 leads to qter syndrome is suspected on the basis of comparison of the clinical and laboratory findings of this patient with those of cases that have been reported as partial 3q trisomy. The common phenotypic features of this syndrome include growth failure and mental or developmental retardation, hypotonia, persistent lanugo, distorted head, congenital glaucoma, short and upturned nose, prominent maxilla, micrognathia, short, webbed neck, short limbs, retroflexed third and fourth toes, cutaneous syndactyly of the second, third and fourth toes, and elevated galactose-1-phosphate uridyl transferase activity in the red blood cells.

Five cases from two nonrelated families with partial trisomy 10q due to a reciprocal translocation t(10;17)(q25;p13) and t(10;11)(q24;q23), respectively, are reported. The phenotypic findings are compared with those of 17 previously published cases; the clinical data justify the conclusion that cases with trisomy 10q show a specific syndrome of mental retardation and malformation characterized by psychomotor retardation, growth retardation, hypotonia, high forehead, flat face, fine and arched eyebrows, antimongoloid slant of the eyes, narrow palpebral fissures, hypertelorism, short nose, bow-shaped mouth, short neck (kypho)scoliosis, and in some cases microcephaly.

Trisomy for the distal third of the long arm of chromosome 19 was observed in a 12-year-old boy and his 9-year-old sister. Both are affected by extremely severe statural and psychomotor retardation. The physical symptoms common to both are dwarfism, micro- and brachycephaly, antimongoloid slant of the eyes, hypertelorism, ptosis, short nose, short philtrum, poorly formed ears, short neck with excess skin, barrel-shaped thorax, diastasis of rectus muscles, kyphosis, sacral dimple, excess of digital arches, pedes valgi, laterally curved big toes, epilepsy and muscular hypotonia. The chromosomal anomaly was transmitted by the mother, who is the carrier of a translocation t(19;20)(19q133;20pter). In the pedigree, extending over four generations, among 30 pregnancies fathered or mothered by 5 carriers resulted in: 6 individuals with normal karyotype, 9 carriers, 2 confirmed and 2 presumptive unbalanced abnormal children, and 10 abortions.

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.

We found marked accumulation of glycogen in the brain in one case of the cerebro-hepato-renal syndrome (CHRS). Glycogen in the form of beta-particles was deposited freely within the nucleus, perikaryon and cell processes of neurons and glial cells. The changes involved the gray matter diffusely but were more prominent in the cerebral cortex. The patient died at the age of 4 months after a clinical course characterized by severe hypotonia, seizures, and apneic episodes. Other neuropathologic findings were developmental malformations of the central nervous systen (CNS) (pachygyria, polymicrogyria, and hypoplasia of the inferior olives), white matter abnormalities (deficiency in myelination and diffuse accumulation of sudanophilic droplets within glial cells), clusters of peculiar "globoid" histiocytes with pleomorphic lipid inclusions, and microglial nodules in gray and white matter. This unusual combination of findings is regarded as characteristic of the CHRS.

The technique of examination, as well as the extent and quality of visualisation are described, basing on a selected case material of patients who had been subjected to stomach surgery; the extensive possibilities of diagnosis are studied. Hypotonia and double contrast offer considerable advantages over the conventional examination of the operated stomach. Assessment of mucosal conditions, especially in the anastomosis range, is facilitated, thus offering a chance to improve the method of diagnosis. Hypotonic double-contrast examination should always be performed if there are no possibilities of endoscopic examination.

Both alcohol embryopathy and diabetic fetopathy were observed in the same female child. The mother was known to be alcoholic as well as diabetic. At birth the signs of diabetic fetopathy predominated: the child showed edematous subcutaneous fat, birth weight was 3650 g. The heart was enlarged. The patient's blood sugar levels ranged from 0 to 1.4 mMol/1 (0-25 mg/dl). Features of alcohol embryopathy were typical craniofacial dysmorphy, hypotonia of muscles and hyperexcitability. Later on the features of alcohol embryopathy predominated: the child became dystrophic with pronounced microcephaly, and the craniofacial dysmorphy clearly resembled other patients with alcohol embryopathy. This observation is in favour of the hypothesis, that alcohol induces cell hypoplasia in the embryo resulting in postnatal growth retardation. Maternal and consequently embryonic and fetal hyperglycemia induced cell hypertrophy in the embryo and fetus, which compensated the effect of alcohol on birth weight in our patient.

Established suprasacral spinal cord injuries usually are associated with detrusor hyperreflexia and varying degrees of detrusor-sphincter dyssynergia. Occasionally, such injuries result in detrusor areflexia or urethral hypotonicity or both. The results of the urodynamic evaluation of 4 patients with suprasacral spinal cord injuries are described. Detrusor areflexia and urethral hypotonicity were demonstrated in 3 cases and urethral smooth muscular hypotonia but preserved reflex detrusor function in 1. It is shown that destruction of the thoracolumbar sympathetic outflow can cause the complete loss of urethral smooth muscular closing function and that resting urethral closure is totally independent of preganglionic cholinergic influences.

A newborn female is described who exhibited a characteristic facial dysmorphology including deep-set eyes, broad nasal bridge, small mouth, high-arched and narrow palate, severly receding mandible and misshapen ears; constant flexion of the proximal interphalangeal joints, and short distal phalanges and nails of fingers; a congenital heart defect; marked muscular hypotonia, motor and growth retardation. She died at 4 months of age. Her karyotype revealed an additional band in 1q. Banding patterns and clinical picture suggest duplication of the segment 1q25 leads to 1q32.

A de novo translocation of 15q to 3p with complete monosomy of 15p and partial monosomy of 15q was detected by trypsin banding on peripheral lymphocytes of a 5-year-old boy with Prader-Willi syndrome (severe mental retardation, dyslalia, cryptorchidism, and muscular hypotonia). The pathogenic role of chromosome 15 abnormalities in the aetiology of this syndrome is discussed.
