A case of multiple benign hemangiomas in a 10-week-old Negro female is presented. At autopsy, numerous cutaneous and visceral sites of involvement were found. The hemangiomas are believed to arise from a multicentric developmental abnormality but appear capable of limited independent growth and tissue destruction. Postmortem angiograms demonstrate the existence of numerous arteriovenous shunts, which are believed responsible for the marked cardiac enlargement and early congestive heart failure in this case, as well as in previously reported cases of infantile hemangioendothelioma of the liver. Visceral hemangiomatosis should be considered as a possible extra-cardiac cause of infantile cardiac hypertrophy or failure of unknown etiology, especially in the infant with cutaneous hemangiomas. Angiographic techniques may be of help in the diagnosis and determination of extent of visceral hemangiomas.

For objective, analyzing the pathogenesis of infertility patients in Zhengzhou and exploring the relevant influential factors. Method: selecting 264 infertility patients in our hospital and peripheral hospitals in the city from March of 2015 to October of 2016 to carry out relevant investigation & research so as to analyze the major pathogeny and related risk factors of 264 infertility patients. For result, for infertility patients, the occurrence of infertility is common in female whether it is primary or secondary. The primary infertility is usually caused by uterus factors, showing the congenital developmental abnormality of uterus. However, the primary cause of secondary infertility is tubal nowhere, commonly and mainly showing frequent abortion frequency.As to male infertility, the idiopathic infertility is mainly related to asthenospermia while the secondary infertility is mainly related to asthenospermia and oligospermia. Conclusion: clinically, there are more causes of infertility. Thus, the reproductive health education and direction need to be strengthened and completed on the male and female during the child-bearing period, and the timely and professional direction needs to be given to the patients with low incidence of infertility to diagnose and treat as early as possible so as to lower the incidence rate of infertility, worthy of attention.

AbstractAlthough allostatic load has been investigated in mood and anxiety disorders, no prior study has investigated developmental change in allostatic load as a precursor to schizotypal personality. This study employed a multilevel developmental framework to examine whether the development of increased allostatic load, as indicated by impaired sympathetic nervous system habituation from ages 3 to 11 years, predisposes to schizotypal personality at age 23 years. Electrodermal activity to six aversive tones was recorded in 995 subjects at age 3 years and again at 11 years. Habituation slopes at both ages were used to create groups who showed a developmental increase in habituation (decreased allostatic load), and those who showed a developmental decrease in habituation (increased allostatic load). Children who showed a developmental increase in allostatic load from ages 3 to 11 years had higher levels of schizotypal personality at 23 years. A breakdown of total schizotypy scores demonstrated specificity of findings to cognitive–perceptual features of schizotypy. Findings are the first to document a developmental abnormality in allostasis in relation to adult schizotypal personality. The relative failure to develop normal habituation to repeated stressors throughout childhood is hypothesized to result in an accumulation of allostatic load and consequently increased positive symptom schizotypy in adulthood.

SummaryTwo cases of median nasal dermoid fistulae are presented. This is an uncommon developmental abnormality which may present either to ENT Surgerys, Plastic Surgeons, or Dermatologists. Although the extent of the tract in our cases was small, careful pre-operative assessment is required as the tract may be ectensive.

A congenital, developmental abnormality of the gingiva, in the form of clinically visible, multiple microcysts, appearing in an infant of 3 months of age, is described. Their duration and eventual disappearance beyond a period of 12 months was noted. Familiarity with this condition is helpful in formulating a favorable prognostic evaluation.

Mondini dysplasia, also known as Mondini malformation, is a developmental abnormality of the inner and middle ears that can cause hearing loss, cerebrospinal fluid (CSF) leakage, and recurrent bacterial meningitis (RBM), which is defined as two or more episodes of meningitis separated by a period of convalescence and the complete resolution of all signs and symptoms. An accurate diagnosis of the underlying pathology is crucial to prevent further episodes from occurring. Herein, we present a three-year-old boy with RBM and unilateral sensorineural hearing loss. During the evaluation to determine the etiology of the RBM, cystic malformation in the cochlea and vestibular dilatation consistent with Mondini dysplasia were detected via computerized tomography (CT) of the temporal bone.

BackgroundAbnormalities presumed to occur during foetal life have been associated with schizophrenia. Polydactyly is a developmental abnormality but no previous association has been reported between Polydactyly and functional psychotic illness.MethodIndividuals with both Polydactyly and a functional psychosis were ascertained during a study of familial schizophrenia.ResultsFive such individuals were ascertained in the course of assessing 234 individuals with familial psychosis, giving a rate of Polydactyly in the sample of around 10 times the general population rate.ConclusionsThis study provides preliminary evidence that Polydactyly is over-represented in individuals with familial schizophrenia and related psychotic illnesses.
