Background: Urinary incontinence in older women is common. Its characteristics and impact on quality of life is not well established since these women are usually reluctant to tell their healthcare providers about the problem.

Objective: To determine the characteristics of urinary incontinence in women and the manner in which it affects patients quality of life.

Methods: Twenty family physicians were requested to distribute a questionnaire to the first 25 consecutive women aged 30 to 75 years who visited their clinic for any reason. The questionnaire covered general health issues, symptoms of urinary incontinence, and quality of life.

Results: A total of 418 women, mean age 50.0 ± 11.8 years, completed the questionnaire (84% response rate). Of these, 148 (36%) reported having episodes of urinary incontinence. Urinary incontinence was found to be associated with older age, menopause, obesity and coexisting chronic disorders. Sixty percent of the women with urinary incon­tinence found it to be a disturbing symptom, and 44% reported that it had a detrimental effect on their quality of life. Only 32% of the affected women had sought medical advice, half of them from their family physician. Treatment was recommended to 66% of those who sought help, and in about two-thirds of these it brought some measure of relief.

Conclusions: Urinary incontinence is a common com­plaint among women attending primary care clinics, but it does not receive appropriate attention, Though it often adversely affects quality of life, only a small proportion of women seek medical advice. Family physicians should raise the issue as a part of the routine general health check-up.
 

Background: Lower urinary tract symptoms are highly prevalent in older men, have been shown to affect men’s quality of life, and may be associated with more serious outcomes.

Objectives: To determine the prevalence of LUTS among men aged 50 years or older registered at family practice centers in Israel and to assess the effect of these complaints on different aspects of their life.

Methods: In a random sample cohort of men aged 50 years and older, fluent in Hebrew, drawn from those registered in four family clinics in Israel, patients identified with LUTS were interviewed by phone using a structured questionnaire.

Results: The prevalence of LUTS in our study was 21%. Less than a third of these patients had low severity LUTS (28%), 59% were rated moderate, and 13% had severe symptoms. Age had a positive correlation with the severity of LUTS, and increasing severity of symptoms had a negative effect on the daily function and quality of life of patients.

Conclusions: Our community-based study shows that LUTS is a common finding among men above the age of 50 (21%) and has a significant negative effect on their quality of life and daily function. Knowledge of these data should make primary care physicians more aware of this common problem and thus improve the treatment and quality of life of these patients by better identification and prompt treatment.

Background: Patients who feel involved in their treatment have better outcomes than those who do not.

Objective: To identify determinants of perceived patient involvement in obstetric care.

Methods: A retrospective study was undertaken in 1,452 (83%) of 1,750 women sampled in November 1995 from maternity wards of 14 general hospitals in Israel. A postal and telephone survey using a self-administered questionnaire included the following variables: hospital (identity number), patients' age, self-reported complications, previous deliveries, education, ethnicity, and number of obstetric interventions performed and/or considered. The main outcome measured was the reported involvement in decisions for obstetric interventions.

Results: Reported full involvement varied from 72% for epidural analgesia to 13% for forceps/vacuum extraction. Factor analysis identified two dimensions of perceived involvement: one for routine” interventions (enema, monitor­ing, IV line and episiotomy), which are performed in Israel mostly by midwives, and another for "special" interventions (forceps/vacuum extraction, epidural or other analgesia, and cesarian section) performed by physicians. Logistic regression identified hospitals, younger age, number of interventions, and Arab ethnicity as correlates of a perceived non-involvement in decisions for "special" interventions.

Conclusions: Clinical setting, age and ethnicity affected patient perception of involvement in decisions for obstetric interventions.

Background: Congenital subependymal pseudocysts are incidental findings that are found in 05-5.2% of neonates during postmortem examination or head ultrasonography. In our institution we detected 10 neonates with CSEPC.

Objective: To investigate associated etiological factors, morphologic characteristics and outcome of CSEPC.

Methods: We performed a meta-analysis of the literature on CSEPC (1967-98), including our 10 cases.

Results: A total of 256 cases of CSEPC were analyzed. Ultrasound diagnosed 77.6% of CSEPC 48.8% were bilateral and 53.4% were located in the caudothalamic groove or head of caudate nucleus. Altogether, 93.5% resolved during 1-12 months of ultrasonographic follow-up. Compared to the general neonatal population, the following features were more prevalent in the CSEPC population: prematurity, maternal vaginal bleeding, preeclamptic toxemia, intrauterine growth restriction, asphyxia, fetal cytomegalovirus and rubella infec­tions, congenital malformations, chromosomal aberrations, infant mortality, and neurodevelopmental handicap. The risk for neurodevelopmental handicap was significantly higher when CSEPC were associated with fetal infections, IUGR, malformations and chromosomal aberrations, or persistence of CSEPC during follow-up. CSEPC infants without any of these four conditions had a low risk for neurodevelopmental handi­cap.

Conclusions: CSEPC are morphologic features of various underlying conditions encountered in the fetus. Association of CSEPC with IUGR, fetal infections, malformations and chromosomal aberrations or persistence of CSEPC indicates a higher risk for future neurodevelopmental handicaps, probably because of the deleterious effects on the fetal brain that are inherent in these conditions. A favorable outcome is expected in the absence of these risk factors.
 

Cancer is a multi-step disease involving a series of genetic alterations that result in the loss of control of cell proliferation and differentiation. Such genetic alterations could emerge from the activation of oncogenes and the loss or malfunctioning of tumor suppressor gene activity. Our understanding of cancer has greatly increased through the use of DNA tumor viruses and their transforming proteins as a biological tool to decipher a cascade of events that lead to deregulation of cell proliferation and subsequent tumor formation. For the past ten years our laboratory has focused on the molecular biology of the human neurotropic papovavirus, JCV. This virus causes progressive multifocal Ieukoencephalopathy, a fatal neuro­degenerative disease of the central nervous system in immunocompromised patients. JCV is a common human virus that infects more than 80% of humans but does not induce any obvious clinical symptoms. The increased incidence of acquired immune deficiency syndrome and the use of immunosuppressive chemotherapy have dramatically raised the incidence of PML. The coincidental occurrence of malignant astrocytes and oligodendrocytes in PML patients, coupled with the induction of glioblastoma in JCV-intected non­human primates, provides intriguing speculation on the association between JCV and CNS malignancies. In this report we discuss clinical data and laboratory observations pointing to the direct involvement of JCV in cancer.

Background: Human chorionic gonadotropin, the pregnancy hormone, is synthesized by trophoblast cells which make up the placenta.

Objective: To determine whether antibody to hCG can be used to specifically detect living trophoblast in vitro by binding to the external membrane.

Methods: Trophoblast was isolated from fresh placentas of women undergoing termination of pregnancy in the first trimester and incubated with monoclonal antibody to hCG. Anti-mouse immunoglobulin G with a fluorescent marker was then added.

Results: Syncytiotrophoblast stained positive on the external surface of the cell, while controls of leukocytes, endometrial cells and hepatocytes were negative.

Conclusion: The hCG monoclonal antibody may be used to specifically detect hCG on the surface of living trophoblast in vitro.
 

Background: Achondroplasia is the most frequent form of disproportionate short stature, characterized by rhizomelic shortening of the limbs. This disorder is inherited as an autosomal dominant trait, although most of the cases are sporadic, a result of a de novo mutation. A recurrent glycine to arginine mutation at codon 380 (G380R) in the transmembrane domain of the fibroblast growth factor receptor 3 gene was found to cause achondroplasia among different populations. This is most uncommon in other autosomal dominant genetic diseases.

Objectives: To determine whether this mutation is also common among Jewish patients from diverse ethnic groups and among the Arab population in Israel.

Methods: We examined the G380R mutation (G>A and G>C transition) and the mutation G375C (G>T transition at codon 375) in 31 sporadic patients and in one family diagnosed clinically to have achondroplasia.

Results: We found the G>A transition at codon 380 in 30 of our patients and the G>C transition in one patient. We were not able to detect any of the three mutations in two patients with an atypical form of achondroplasia.

Conclusions: Our results further support the unusual observation that nucleotide 1138 of the FGFR3 gene is the most mutable nucleotide discovered to date across different populations.
