Ten cases of Lesch-Nyhan syndrome have been followed for 3-19 years (mean, 11 years and four months). Criteria of Lesch-Nyhan syndrome were restricted to the following: complete absence of hypoxanthine-guanine phosphoribosyltransferase (HPRT) in hemolysate and fibroblast, spasticity, choreoathetosis, mental retardation, self-mutilation, and occurrence in males. Two patients have died of pneumonia and two died suddenly. However, autopsies produced no positive findings. Hyperuricemia has been controlled by benzbromarone in nine patients. One patient did not take any medical treatment and died suddenly when he was 19 years old, but showed no gouty signs. Patients with Lesch-Nyhan syndrome indicated no change or aggravation of choreoathetosis or spasticity. Self-mutilation was difficult to control by any treatment with continuing effect. After the age of ten, self-mutilation declined in seven cases, and in one patient disappeared completely. Mental delay was remarkable and suspected developmental age (DA) was 7 months - four years and 10 months (chronological age, 7 years and five months - 19 years and 6 months). Mean DQ score was 15.6. Physical development was severely delayed, and weight age was 28.9-46.4%, mean 37.4% of chronological age. Future investigations will evolve clarification of CNS signs and its treatment, and etiological research of sudden death.

It is well known that intraventricular tumors are occasionally seen in patients with tuberous sclerosis. We have experienced two cases of tuberous sclerosis with intraventricular tumor. Case 1: an 8-year-old girl was admitted to our clinic because of headache and vomiting of one month's duration. She had adenoma sebaceum, mental retardation and seizures clinically, and a large tumor was found in the right lateral ventricle by pneumoventriculography. Partial removal of the tumor was performed by the right frontal transcortical approach, but she later died of pneumonia. Necropsy revealed hamartomatous disease characterized by multiple focal tumor-like malformations in various organs including the brain, kidneys, heart, lungs and liver. The histological diagnosis of the intraventricular tumor was subependymal giant cell astrocytoma. Case 2: a 6-year-old boy was admitted to our clinic because of headache of one year's duration. He had also suffered from seizures since 6 months of age. Adenoma sebaceum was noted in the cheeks. CT revealed a medium sized tumor at the right foramen of Monro and the moderately dilated right lateral ventricle and several calcified deposits in the lateral ventricle wall. The tumor was subtotally removed by the right frontal transcortical approach. The pathological examination showed subependymal giant cell astrocytoma. Now 6 years after the operation he is enjoying a normal school life. In our cases, intraventricular tumors associated with tuberous sclerosis were of a typically benign histological appearance, that is subependymal giant cell astrocytoma.(ABSTRACT TRUNCATED AT 250 WORDS)

Gastroesophageal reflux (GER) in the pediatric patient is a frequently recognized problem. Unlike the adult, in whom symptoms relating to esophagitis predominate, the infant and child may present with a variety of respiratory problems, vomiting and/or growth failure. GER is often seen in association with other conditions and must be considered in the evaluation of any pediatric patient with chronic recurring respiratory problems, vomiting or failure to thrive (FTT). Thirty-eight pediatric patients have been surgically managed at West Virginia University from 1977-1983 for GER. The patients fall into several different patterns of presentation and associated problems. Nine premature infants all with bronchopulmonary dysplasia (BPD) have undergone fundoplication for FTT, worsening BPD, and pneumonia. Seven infants and two older children had GER associated with previous esophageal atresia repairs. Esophagitis, vomiting and growth failure were the predominant complaints in this group, though all nine patients had recurring respiratory symptoms as well. Syndromes involving mental retardation and neurologic dysfunction affected another group of five patients, all of whom presented with the complications of long-term esophagitis. The remaining 15 children were otherwise healthy infants who had predominantly respiratory symptoms due to GER. The benefits of fundoplication in these severely affected infants and children far outweigh the relatively few complications. In the carefully selected patient, surgical management of GER is dramatically successful.

Over 10 million cases of sexually transmitted diseases (STD) occur annually, 86 percent of them in 15- to 29-year-olds. The most common STDs are trichomoniasis, gonorrhea, non-gonococcal urethritis, genital herpes, and syphilis. In 1950 the reported syphilis rate was 146 per 100,000. The rate decreased to 30 per 100,000 by 1978, resulting in approximately 80,000 new cases of syphilis a year. During the same time span the gonorrhea rate increased from 192 cases per 100,000 to 468 cases per 100,000. In each year between 1967 and 1976, reported cases of gonorrhea increased between 10 and 15 percent. Between 1976 and 1978 the annual increase was less than 1 percent, but the total number of case of gonorrhea still exceeded 2.5 million. In addition to the large number of syphilis and gonorrhea cases, 3 million cases of trichomoniasis, 2.5 million cases of non-gonococcal urethritis, and 500,000 cases of genital herpes occur annually. The most serious complications caused by sexually transmitted agents are pelvic inflammatory disease, sterility, infant pneumonia, infant death, birth defects, and mental retardation. There is clear evidence that both the quality of the services and the attitudes with which they are delivered are important in attracting those who need STD services. While existing programs are interrupting the transmission of syphilis and gonorrhea, many vulnerable groups are not yet being served. To approach them effectively will require not only the efforts of STD clinics and investigators but also those of family planning clinics, private physicians, diagnostic and public health laboratories, and schools and other educational institutions.

A newborn baby presented with hyaline membrane disease, interstitial pneumonia, jaundice, hepatosplenomegaly, and unusual bone manifestations with lytic and sclerotic bone lesions and virtually absent periosteal reaction. He subsequently developed intracranial calcifications and mental retardation. The pneumonia and hepatosplenomegaly resolved. At the time of the delivery, a sibling was suffering from a severe undetermined viral infection. The clinical evolution of the disease and the radiologic findings led us to believe that this patient had a prenatal viral infection. The laboratory tests and the histologic picture of the bone biopsy supported the diagnosis.

The outcomes for five patients with retinoblastoma and constitutional chromosomal abnormalities involving the long arm of chromosome 13 are reported. All patients demonstrated developmental delay and mental retardation. Four of these patients are alive 23, 21, 15, and 1 year from diagnosis; one died of pneumonia with septicemia. Each of the four survivors has, with aging, shown hypotonia, mutism, contractures, and inability to function independently.

Lissencephaly ("smooth brain") is a brain malformation characterized by a smooth cerebral surface, incomplete neuronal migration, and secondary abnormalities such as mental retardation, seizures, and minor facial dysmorphisms. Recent reports have produced evidence supporting several different causes including submicroscopic deletions in chromosome band 17p13.3, autosomal recessive inheritance, intrauterine infection, and intrauterine perfusion failure. We describe the clinical manifestations in seven patients with lissencephaly, and review pertinent studies regarding possible causes. The clinical manifestations were uniformly severe. All patients had severe mental retardation, hypotonia, often combined with spastic paralysis, and infantile spasms which did not respond to treatment. Most had poor growth, postnatal microcephaly, feeding problems, and frequent respiratory infections including pneumonia. None had other significant birth defects. Appropriate studies include computed tomography or magnetic resonance imaging (sometimes both), chromosome analysis, DNA analysis of the lissencephaly region on chromosome 17, electroencephalography and sometimes metabolic studies.

A 33 year-old man with undiagnosed neuropathy showing mental retardation and involuntary movements has been nourished for a long period by total parenteral nutrition (TPN) because of frequent vomiting and repeated aspiration pneumonitis. After ten months' TPN, macrocytic anemia and neutropenia developed and iron preparation was administered without hematological improvement. Bone marrow examination revealed normocellular marrow without features of megaloblastosis and dysplasia. In some erythroblasts and immature myeloid cells, vacuoles were observed and mature granulocytes were reduced in the bone marrow. Both serum copper and ceruloplasmin were very low (12 micrograms/dl and 7mg/dl, respectively). Thus, oral administration of copper sulfate resulted in marked increase of reticulocytes and subsequent improvement of anemia and neutropenia within two months. Copper deficiency is a rare condition, but during an unusual nutrition such as TNP, hematological abnormality due to copper deficiency must be noticed to occur.

Lobar pneumonia due to Escherichia coli is rare. Most lobar pneumonias are caused by either Streptococcus pneumoniae or Klebsiella pneumoniae, and most E coli pneumonias are bronchopneumonias. We report an acute fulminant course of E coli lobar pneumonia in a 37-year-old patient who was profoundly retarded, institutionalized, and nonimmunosuppressed and who died within 2 days of developing initial symptoms. Antemortem blood and postmortem blood and lung specimens isolated pure cultures of E coli. The source of infection in E coli lobar pneumonia is not clear in this patient or in the few cases that have been reported. We postulate that nasopharyngeal colonization of E coli in those who are institutionalized with mental retardation may predispose these patients to E coli pneumonia. Our case illustrates features of pneumonias that are unique in the institutionalized, mentally retarded patient population (ie, the relatively high prevalence of nasopharyngeal colonization of E coli, a higher incidence of E coli pneumonia than in other institutionalized populations, the often fulminant course of the disease), as well as the need for early, aggressive treatment including antibiotics effective against gram-negative bacteria.

Approximately 0.5-1% of all newborns are born infected with cytomegalovirus (CMV), but of these only one out of ten show symptoms at birth, most often with hepatosplenomegaly, thrombocytopenia, and/or brain affection. Of the remaining nine, one may later develop sequelae with hearing loss and/or mental retardation. CMV infection may also be acquired perinatally or in the newborn period, and may cause pneumonia and/or sepsis, possibly also gastrointestinal symptoms like blood in the stool, and poor weight-gain. We have diagnosed CMV infection in ten neonates and infants, and describe these patients in terms of symptoms, diagnosis and treatment. Ganciclovir is being tested in clinical trials as a treatment for congenital CMV infection, and was given to two of our patients with apparently good results.
