ABSTRACT
OBJECTIVES: This study was carried out to determine the prognosis, and the clinical approach, in fetuses with umbilical cord cysts, during the second and third trimesters of gestation, according to our experience and data in the current literature. METHODS: We identified 10 fetuses with umbilical cord cysts that were diagnosed during the second and third trimesters of pregnancy at three referral centers. All underwent detailed ultrasound evaluation at the time of diagnosis and during follow-up. Prenatal karyotype testing was offered to all women. A MEDLINE review of the literature published from 1980 to 2009 was carried out to identify previous studies and case reports of fetuses with umbilical cord cysts. RESULTS: In our series of 10 cases, significant additional abnormalities were observed in two during a detailed sonogram. In one case, trisomy 18 was diagnosed, leading to pregnancy termination, and in the other case a neonate with heart defects and a normal karyotype was born. These results differ from those reported in the literature, in which the association between second- and third-trimester umbilical cord cysts and fetal anomalies ranged from 38 to 100%. CONCLUSIONS: In our study, as in other publications, an association was found between the presence of second- and third-trimester umbilical cord cysts and fetal anomalies. The strong association between second- and third-trimester umbilical cord cysts and aneuploidy in the literature seems to be biased, mainly because of the tendency to report abnormal cases. When these findings are accompanied by additional sonographic abnormalities, the association with aneuploidy is clear and should be an indication for fetal karyotype testing.

Cytokines are secreted proteins that act as local immunological mediators. Increased seminal cytokine concentrations are associated with fertility problems. The purpose of the present study was to investigate the presence of IL-2alpha, and IL-2beta receptors on fresh and isolated sperm by flow cytometry and transmission electron microscopy. Twenty sperm samples from oligospermic men were incubated with CD25, a mouse monoclonal antibody specific for IL-2alpha-chain receptor, and CD122, a mouse monoclonal antibody specific for IL-2beta-chain receptor. The strong initial fluorescence intensity and, subsequently, a labeling index yielded by CD25 and CD122 decreased in sperm centrifuged on a Percoll gradient (p < .05). The expression of CD25 and CD122 correlated negatively with fresh sperm concentration, but in sperm centrifuged on a Percoll gradient there was no correlation. Labeling with CD25 and CD122 antibody was evident on the head and the middle piece in fresh sperm, while in sperm centrifuged on a Percoll gradient a weak labeling was observed only on the principal piece. The authors have identified and localized cytokine receptors on human sperm for the first time. Cytokine receptors may be involved in the regulation of pathophysiological events in sperm cell functions and male infertility. The exact pathway involved in modulation of these receptors requires further investigation. These results contribute to the understanding of cytokine-sperm relationships.

OBJECTIVE: The aim of this study was to examine whether delirium has specific clinical subtypes. METHOD: One hundred and eighty-three elderly subjects meeting DSM-IIIR criteria for delirium were evaluated using a 19-item symptom check-list assessing different dimensions of delirium symptomatology. Exploratory factor analysis was conducted in order to examine which symptoms clustered. RESULTS: Factor analysis confirmed the existence of two different clusters of symptoms: first, symptoms of hyperalert/hyperactive features (agitation, hyper-reactivity, aggressiveness, hallucinations, delusions); and second, symptoms of hypoalert/hypoactive features (decreased reactivity, motor and speech retardation, facial inexpressiveness). CONCLUSION: This preliminary study seems to support the evidence of hypoactive and hyperactive subtypes of delirium, even though their aetiology and prognostic values need to be further examined.

The existence of hyperactive, hypoactive, or mixed clinical subtypes of delirium is widely accepted. But relationships between these motor profiles and etiology or outcome remain unclear. The aim of this study was to compare etiologic and outcome profiles in a case series of 183 elderly patients (mean age = 84.1 years, SD = 5.9) consecutively admitted into the geriatric wards of two French university hospitals or referred to a geriatric psychiatry consultation-liaison unit within a Swiss university hospital. All patients met DSM-III-R criteria for delirium and were classified into clinical subtypes according to the results of a previous factor analysis of scores on a 19-item checklist rating a wide range of delirium symptoms. The hyperactive subtype was more frequent (n = 85, 46.5%) than the unspecified (n = 50, 27.3%) and hypoactive subtypes (n = 48, 26.2%). There was no significant difference in terms of etiologic or outcome profile between clinical subtype groups. The presence of acute metabolic disorders, cardiovascular disease, and hyperthermia as etiologic factors was significantly associated with full recovery of the episode at 3 weeks follow-up, whereas probable preexisting dementia was significantly associated with partial recovery or failure to recover.

The male to female ratio in newborns of grand grand multiparous women was evaluated in 569 Jewish Orthodox women and 28 Muslim women. A total of 882 babies was born on the > or = 10th delivery; 460 (52.2%) were males and 422 (47.8%) were females (sex ratio = 1.06). Newborn sex ratio did not significantly change with respect to birth order or maternal age. It is suggested that parity and increasing maternal age do not affect the sex ratio of newborns and that ethnic and environmental variables may play a role in the deviations in offspring sex ratio observed among different populations.

Using explicit criteria contained in the DSM III R, we collected in a prospective cohort study clinical features, outcome and risk factors from two cohorts of delirium in hospitalized elderly patients: 138 hospitalized in geriatric department and 45 patients admitted to an acute and comprehensive care hospital. The clinical features were assessed using a quantitative scale (developed by Derouesné). Delirium was unrecognized or misdiagnosed by physicians in 34% of the cases. The onset was known only two thirds of cases. The incidence of hyperactive type, prolonged hospital stay, poor outcomes (persistent delirium leading up to dementia) were highest in subjects admitted in comprehensive hospital. The etiology of delirium is complex and multifactorial. An underlying cause was identified in 80% of patients. The length or the worsening of delirium was significantly higher in patients with psychiatric or dementia comorbidity (OR: 0.2; IC 95%: 0.1-0.5). The prognosis was better in patients without psychoactive medications (OR: 0.2; IC 95%: 0.1-0.4) or with metabolic abnormalities or acute diseases and disorders (OR: 3.3; IC 95%: 1.5-7.6). The predisposing factors to the development of dementia were prior use of psychoactive medications and signs of prior cognitive impairment. This article suggests delirium in elderly patients is associated with several outcomes. The prognosis should be improved at admission by specific scale and an evaluation of predisposing and precipitating factors.

Thyroid disorders are known to manifest occasionally as isolated psychiatric disorders. In order to determine whether thyroid dysfunctions could play a significant role in the pathogenesis of psychiatric disorders in the elderly, the prevalence of thyroid disorders was compared in a group of psychogeriatric patients and in a group of nonpsychiatric elderly patients. Thyroid function screening was performed in 157 patients consecutively admitted to a psychogeriatric unit, and the prevalence of hypothyroidism was determined in the different groups of psychiatric disorders (senile and multi-infarct dementia, organic brain syndrome of other etiologies, psychotic depression, neurotic depression, chronic delusional state, acute confusional state, and personality disorder). Thyroid function screening was performed similarly in 104 unselected elderly patients admitted to the medico-surgical admission unit of the University hospital to assess the prevalence of hypothyroidism in a general, nonpsychiatric, elderly population. Eight patients were diagnosed as hypothyroid based on an elevated basal thyrotropin (TSH) and on thyrotropin-releasing hormone (TRH) test in the total number of patients, two in the nonpsychiatric and six in the psychiatric group. Three had clinical hypothyroidism, with decreased total and free T4 and T3 plasma levels in addition to increased basal TSH, five had biochemical hypothyroidism, with normal T4 and T3 levels and an excess TSH response to oral TRH. The prevalence of hypothyroidism in the two groups did not differ significantly (1.9% in the nonpsychiatric versus 3.8% in the psychiatric group). The prevalence of hypothyroidism in a subgroup of 88 patients with senile and multi-infarct dementia was 2.3%.(ABSTRACT TRUNCATED AT 250 WORDS)
