[Endometriosis: Assessment of the Ultrasound-Based Endometriosis Staging System score (UBESS) in predicting surgical difficulty]. / Endométriose : évaluation du score Ultrasound-Based Endometriosis Staging System (UBESS) dans la prédiction de la difficulté chirurgicale.

OBJECTIVES: Surgical management of endometriosis may require different levels of surgical skill which influences the orientation of the patient. The Ultrasound-Based Endometriosis Staging System (UBESS) is a score developed in 2016 to predict the difficulty of surgery. To study the correlation between UBESS score and two main surgical classifications in the literature. METHODS: Study performed at the center of Poissy, France, between July 2016 and December 2017. Patients who underwent prospective UBESS staging then operated of their endometriosis were included. The patients were classified according to the levels of surgical difficulty of the Royal College of Obstetricians and Gynecologists (RCOG) and the classification created by Chi et al. The criterion of judgment was the correlation between the UBESS stages and RCOG and CHI levels. In a second analysis, we determined the predictive value of the operative plan for items included in the systematic sonographic evaluation described by Menakaya et al. RESULTS: Thirty-three patients were included in the study. Correlation was found to be low between UBESS and RCOG (θ=0.22) and between UBESS and CHI (θ=0.30). The prediction of the operative plan was good for endometrioma, sites specific tenderness, sliding sign, vaginal and digestive tract involvement; but modest for the anterior compartment and uterosacrals ligaments. CONCLUSION: In our study on a small number of patients, the UBESS score does not adequately predict the surgical difficulty. Taken separately, the items of systematic sonographic evaluation based on 5 domains successfully predict the operative plan.

Precaval positive sentinel lymph node with bilateral negative pelvic sentinel lymph node in low-risk endometrial cancer patient.

We here describe a case report of a positive precaval sentinel lymph node with negative pelvic sentinel lymph node in a patient with endometrial cancer. A 45-years-old woman was diagnosed with a grade 2 endometrioid carcinoma of the endometrium. She was treated with a hysterectomy and bilateral salpingo-oophorectomy, associated with dissection of sentinel lymph nodes (SLNs). We detected bilateral external and common bilateral iliac nodes and one precaval node. At pathological examination the pelvic nodes were non-metastatic, but the precaval node was positive. In this patient, sentinel node biopsy improved risk-assessment and adjuvant treatment.

What about sentinel lymph node biopsy for early breast cancer during pregnancy?

Pregnancy-associated breast cancer is rare, but this clinical situation arises in 1/10,000-1/3000 pregnancies. In patients presenting an early-stage breast tumor devoid of clinically pathological lymph node, sentinel lymph node (SLN) biopsy has not yet been validated as a routine procedure for pregnant women due to the lack of data in the literature. The blue dye injection is not recommended because of 2% theoretical risk of anaphylactic shock. Several studies have shown that Tc99m injection at conventional dose between 12.1 and 18.5MBq exposed the fetus to an irradiation between 0.011 and 0.0245mSv much below the 50mSv recommended threshold. As evidenced by lymphoscintigraphy scans, the dose of injected Tc99m is localized at the injection site and in the SLN. According to the literature, the SLN technique does not seem to impact the fetal or obstetrical prognosis. Studies involving larger cohorts are required to confirm these data and to indicate this technique in pregnant women. Considering the benefit for the patient and the low risk incurred on both fetal and obstetrical levels, it appears reasonable to discuss the indication of SLN on a case-by-case basis in multidisciplinary oncologic meetings.

Secular trends in the impact factors of SLE publications over a 45-year period-a systematic review.

OBJECTIVE: We assessed publication bias in the field of systemic lupus erythematosus (SLE) by conducting a search of randomized, controlled trials (RCTs) on SLE therapies that had been published over the past 45 years. Our aim was to assess a potential publication bias by determining whether RCTs reporting positive results, RCTs with placebo arms, biologics RCTs, and industry-funded RCTs are more likely to be published in journals with higher impact factors (IFs). METHODS: We conducted a systematic review of all RCTs registered in PubMed between 1 January 1975 and 1 November 2016. Each RCT was classified as having a positive result (PR) or a negative result (NR). The IF of each journal was determined for the year of publication. RESULTS: Our search yielded 233 relevant RCTs. There was no significant difference in IFs between studies with NRs and those with PRs or between studies that were financially supported by commercial companies compared to studies that were not. However, there was a significant correlation between sample size and the journal's IF. CONCLUSIONS: IF scores of RCTs in the field of SLE are influenced by sample size and not biased by either a tendency to report PRs or by being funded by pharmaceutical companies or any other commercial sources.

Evaluation of adherence to French clinical practice guidelines in the management of pregnancy loss issued by the French College of Obstetricians and Gynecologists, one year after publication: A vignette-based study.

OBJECTIVES: To assess the adhesion of French obstetricians and gynecologists to the French clinical practice guidelines for pregnancy loss, issued by the French College of Obstetricians and Gynecologists, one year after publication. METHODS: An online vignette-based study was emailed to a sample of French obstetricians and gynecologists to compare their management of women with missed early miscarriage and incomplete early miscarriage. A descriptive statistical analysis was performed comparing the rates of appropriate management for these two indications before and after the release of the guidelines. RESULTS: Of the 404 specialists contacted, 143 completed the questionnaire. Forty-three percent stated that they had changed their practices following the release of the guidelines. The rate of adhesion was moderate for the management of missed early miscarriage (53% after publication of the guidelines versus 42% before, P=0.001) with a trend to avoid watching-and-waiting management. The rate of adhesion was poor for the management of incomplete early miscarriage (43% after the publication of the guidelines versus 27% before, P<0.001) with a lower use of misoprostol. CONCLUSION: Adhesion to the French guidelines appears to be moderate for the management of missed early miscarriage and low for the management of incomplete early miscarriage.

Publication outcomes of neonatology abstracts presented at the Pediatric Academic Societies meeting.

OBJECTIVE: To examine publication outcomes of neonatology abstracts presented at Pediatric Academic Society (PAS) meeting, and to analyze variables affecting publication. STUDY DESIGN: All neonatology studies accepted for presentation (oral or poster) at 2008 PAS meeting were identified. A biphasic manual PubMed search of published articles was performed using a pre-designed algorithm. RESULTS: A total of 1078 neonatology abstracts were presented at the meeting, among them 481 (44.62%) published by 2016. Abstracts presented orally versus posters (56.11 versus 42.32%; P<0.001) and basic science versus clinical abstracts (53.08 versus 40.2%; P<0.001) were more likely to be published. Positive or negative results of a study or its sample size did not predict rates of publication. CONCLUSIONS: Less than half of the abstracts presented at the PAS meeting were published within 8 years. Oral presentations were more likely to be published than posters.Journal of Perinatology advance online publication, 6 April 2017; doi:10.1038/jp.2017.46.

Cynodon dactylon extract as a preventive and curative agent in experimentally induced nephrolithiasis.

Cynodon dactylon (Poaceae family) decoction was used in the treatment of kidney stones. However, no scientific study was undertaken so far to demonstrate the beneficial effect of the plant. Thus, the aim of the current study is to evaluate the effect of Cynodon aqueous extract as a preventive and curative agent in experimentally induced nephrolithiasis in a rat model. Ethylene glycol (EG) was used in the experiment to induce calcium oxalate (CaOx) deposition into kidneys. In preventive protocol, Cynodon decoction was administered in the same day with EG to evaluate the ability of the extract to prevent crystal deposition. However, in curative protocol, rats were first rendered nephrolithiasic and then the extract was administered to assess the ability of the plant to eliminate the pre-existing crystal deposition. In both protocols, urinary biochemical and other variables were measured during the course of the study. Crystalluria and renal histology were examined as well. The results showed that, in both protocols, all measured variables were similar for both the rat groups. Nevertheless, urinary biochemical analysis was apparently unaffected by the extract except oxalate in preventive protocol, and calcium, sodium, and potassium in curative protocol which were significantly highly excreted in treated rats compared to untreated animals. Crystalluria was characterized mostly by the presence of large quantities of CaOx monohydrate and CaOx dihydrate particles in untreated rats. However, crystalluria was mainly dominated by the presence of CaOx dihydrate particles with reduced size. The most apparent beneficial effect of Cynodon extract was seen in kidney tissues where reduced levels of CaOx deposition have been noticed especially in medullary and papillary sections from treated rats. We concluded that C. dactylon extract has beneficial effect in preventing and eliminating CaOx deposition into kidneys. Such findings provide a scientific explanation for its use in the treatment of kidneys stones.

Clinical and laboratory presentation of EBV positive infectious mononucleosis in young adults.

Clinical descriptions of Epstein-Barr virus (EBV) positive infectious mononucleosis (IM) are rare and their results are inconsistent. Over a 4-year period, we prospectively studied 590 young adults with clinically suspected IM, all of whom were tested for the presence of EBV IgM antibodies. We investigated the demographical, clinical and laboratory features of subjects with positive EBV IgM serology and heterophile antibodies. Contrary to previous studies, we found a seasonal disease pattern with a peak incidence during summer months, and a lower-than-expected prevalence of lymphadenopathy (88.9%), leucocytosis (46.2%), atypical lymphocytosis (89.2%) and elevated liver enzymes (57.9%). The prevalence of hyperbilirubinemia was relatively high (14.9%). The classic triad of fever, sore throat and lymph-adenopathy had relatively low sensitivity (68.2%) and specificity (41.9%) for EBV infection. Our study provides a complete and updated description of the clinical and laboratory presentation of laboratory confirmed IM, which is important for both clinicians and epidemiologists.

Prophylaxis of calcium oxalate stones by Herniaria hirsuta on experimentally induced nephrolithiasis in rats.

OBJECTIVE: To evaluate the prophylactic potential of a herbal decoction from Herniaria hirsuta, a medicinal plant widely used in Morocco to treat kidney stones, by assessing the effect of oral administration in experimentally induced calcium oxalate (CaOx) nephrolithiasis in rats. MATERIAL AND METHODS: Two groups of six rats each were rendered nephrolithic by treating with ethylene glycol 0.75% and ammonium chloride 1% for 3 days, and then ethylene glycol only for 3 weeks. Maintained on ethylene glycol, one group of rats was also given 1 mL/day of the plant decoction, while the others received 1 mL of water instead for 2 weeks. Urine samples (24 h) were collected individually at 1, 3, 7, and 14 days for physicochemical analysis. On completing the treatment the kidneys were collected and analysed by light microscopy. RESULTS: The water intake and diuresis decreased in the treated rats; there was no significant difference in urinary pH between the groups. Urinary chemistry was apparently unaffected by the plant extract, except for the magnesium content, which was higher in treated rats. Crystalluria was characterized by the excretion of large CaOx monohydrate and dihydrate crystals in untreated, but smaller crystals in treated rats. The histology showed large deposits of CaOx crystals in all parts of the kidney in untreated rats but with almost no deposits in those of treated rats. CONCLUSION: H. hirsuta has an impressive prophylactic effect on CaOx stones in nephrolithic rats; the effect did not seem to be mediated by biochemical or diuretic changes.

Does breastfeeding protect against allergic rhinitis during childhood? A meta-analysis of prospective studies.

UNLABELLED: The effect of breastfeeding on the development of allergic rhinitis and other atopic conditions has been assessed in many studies but remains controversial. To elucidate this issue, a systematic review was conducted of prospective studies that evaluated the association between exclusive breastfeeding during the first 3 mo after birth and allergic rhinitis. The 1966-2000 MEDLINE databases were searched and the reference lists of relevant articles were reviewed according to predetermined inclusion criteria. The methodological aspects of each study, duration and exclusivity of breastfeeding, outcome measures, control for potential confounding variables and other factors were assessed, and estimates of the association between breastfeeding and allergic rhinitis were abstracted independently by the investigators using a standardized approach. Six prospective studies met the inclusion criteria. The summary odds ratio for the protective effect of breastfeeding was 0.74 (95% confidence interval 0.54-1.01). The effect estimate in studies of children with a family history of atopy was 0.87 (95% confidence interval 0.48-1.58). CONCLUSION: Exclusive breastfeeding during the first 3 mo after birth protects against allergic rhinitis in children, both with and without a family history of atopy. The protective association, although of borderline statistical significance, was substantial. Larger prospective studies with strict methodology and longer periods of follow-up are needed.

Skin indurations in response to tuberculin testing in patients with nontuberculous mycobacterial lymphadenitis.

Mantoux results were examined for 29 children with culture-proven nontuberculous mycobacterial lymphadenitis, and 4 species were isolated: Mycobacterium avium-intracellulare complex (from 14 patients [48%]), Mycobacterium haemophilum (from 12 [41%]), Mycobacterium simiae (from 2 [7%]), and Mycobacterium scrofulaceum (from 1 [3%]); the median indurations for each species were 15.5 mm, 14.5 mm, 20 mm, and 23 mm, respectively, and in 17 cases (59%), they were > or =15 mm. In regions with a low incidence of tuberculosis, lymphadenitis thought to be due to nontuberculous mycobacteria should be managed as such, regardless of Mantoux results, thereby avoiding antituberculosis treatment.

Occurrence of supernumerary nipples in children with kidney and urinary tract malformations.

The reported data on the association of kidney and urinary tract malformations with supernumerary nipples are contradictory. We examined 200 children, ages 1 month-16 years, who were being followed because of recurrent urinary tract infection for supernumerary nipples. The patients were divided into two groups: those who were found to have urinary tract malformations on radiographic studies (n=92) and those who were not (n=108). All children were examined for any abnormal pigmentation along the milk line, and the entire body was examined for ectopic supernumerary nipples. Two of the children with proved urinary tract pathology and two of the children with no urinary tract pathology had supernumerary nipples. The odds ratio for having supernumerary nipples among the first group was 1.18 (95% CI: 0.084-16.53, p=0.627). Our results indicate no association between kidney and urinary tract malformations and supernumerary nipples. We believe the message to the practicing physician is that there is no need for radiographic or ultrasonographic investigation of the urinary tract in asymptomatic children found to have supernumerary nipples on routine physical examination.

Breast-feeding and the onset of atopic dermatitis in childhood: a systematic review and meta-analysis of prospective studies.

BACKGROUND: Despite the numerous studies on the possible protective effect of breast-feeding against the onset of atopic dermatitis during childhood, this issue remains controversial. OBJECTIVE: We conducted a systematic review with meta-analysis of prospective studies that evaluated the association between exclusive breast-feeding during the first 3 months after birth and atopic dermatitis. METHODS: A comprehensive search of the 1966-2000 MEDLINE database and review of the reference lists of relevant articles identified 18 prospective studies that met the predefined inclusion criteria. By means of a standardized approach, 2 of the investigators independently assessed the methodologic quality of the studies, duration and exclusivity of breast-feeding, outcome measures, and control for potential confounding factors. The same approach was applied during data abstraction and evaluation of the estimates of association. Summary measures of association were then calculated. RESULTS: The summary odds ratio (OR) for the protective effect of breast-feeding in the studies analyzed was 0.68 (95% confidence interval [CI], 0.52-0.88). This effect estimate was higher in the group of studies wherein children with a family history of atopy were investigated separately (OR = 0.58; CI, 0.41-0.92) than in those of combined populations (OR = 0.84; CI, 0.59-1.19). A small subset of studies of children without a history of atopy in first-degree relatives showed no association between breast-feeding and the onset of atopic dermatitis (OR = 1.43; CI, 0.72-2.86). CONCLUSION: Exclusive breast-feeding during the first 3 months of life is associated with lower incidence rates of atopic dermatitis during childhood in children with a family history of atopy. This effect is lessened in the general population and negligible in children without first-order atopic relatives. Breast-feeding should be strongly recommended to mothers of infants with a family history of atopy, as a possible means of preventing atopic eczema.

Breast-feeding and the risk of bronchial asthma in childhood: a systematic review with meta-analysis of prospective studies.

BACKGROUND: The protective effect of breast-feeding on the development of childhood asthma remains a matter of controversy. We conducted a systematic review of prospective studies that evaluated the association between exclusive breast-feeding during the first 3 months after birth and asthma. STUDY DESIGN: We searched the 1966-1999 MEDLINE database and reviewed reference lists of relevant articles to identify 12 prospective studies that met pre-stated inclusion criteria. Methodological aspects of the studies, duration and exclusivity of breast-feeding, and outcomes were assessed. Effect estimates were abstracted by the investigators, using a standardized approach. RESULTS: The summary odds ratio (OR) for the protective effect of breast-feeding was 0.70 (95% CI 0.60 to 0.81). The effect estimate was greater in studies of children with a family history of atopy (OR = 0.52) than in studies of a combined population (OR = 0.73). CONCLUSIONS: Exclusive breast-feeding during the first months after birth is associated with lower asthma rates during childhood. The effect, caused by immunomodulatory qualities of breast milk, avoidance of allergens, or a combination of these and other factors, strengthens the advantage of breast-feeding, especially if a family history of atopy is present.

New insight into calcinosis of juvenile dermatomyositis: a study of composition and treatment.

Milk of calcium developed in 2 children with juvenile dermatomyositis. The fluid of the collection contained macrophages, interleukin-6, IL-1, and tumor necrosis factor. The patient who had dystrophic calcinosis had a dramatic improvement with the introduction of alendronate. These findings suggest that calcinosis of juvenile dermatomyositis may be mediated by activated macrophages and that alendronate can be an effective treatment for this condition.

Association of anorexia nervosa with the high activity allele of the COMT gene: a family-based study in Israeli patients.

Anorexia nervosa (AN) is a common, severe and disabling psychiatric disorder, characterized by profound weight loss and body image disturbance. Family and twin studies indicate a significant genetic contribution and pharmacological data suggest possible dysfunction of the serotonergic and dopaminergic pathways. Catechol-O-methyltransferase (COMT) is a candidate gene for mediating susceptibility to AN since it is involved in the dopamine catabolism and because its functional polymorphism (Val/Met 158) determines high (H) and low (L) enzymatic activity alleles. Fifty-one Israeli AN patients and their parents were genotyped with the COMT polymorphism. Using the haplotype relative risk (HRR) method it was found that the frequency of the H allele among alleles transmitted to AN patients from their parents was significantly higher than in those not transmitted (68% vs 51% chi(2) = 5.20, df = 1, P = 0.023, odds ratio: 2.01). Transmission disequilibrium test (TDT) revealed that out of 49 heterozygote parents the H allele was transmitted to AN patients 33 times while the L allele was transmitted only 16 (McNemar's chi(2) = 5.90, df = 1, P = 0.015). Our study suggests that the COMT gene is associated with genetic susceptibility to AN, and that individuals homozygous for the high activity allele (HH) have a two-fold increased risk for development of the disorder.

Recurrent facial nerve palsy in paediatric patients.

UNLABELLED: The aim of the study was to investigate the clinical presentation and prognosis of recurrent facial nerve palsy (RFNP) in children. The files of 182 patients referred to the Schneider Children's Medical Centre of Israel for neurological evaluation of isolated peripheral facial nerve palsy between October 1992 and December 1998 were reviewed. RFNP was found in 11 patients (9 females, 2 males), with an incidence of 6%. In two males, the aetiology was traced to Melkersson-Rosenthal syndrome and these patients were separated from the rest of the group. Three children had two episodes of facial nerve paresis which completely resolved clinically within several weeks. Six other children underwent electrophysiological studies. Two of the latter with residual neurological damage, and one child with abnormal blink reflex only, showed decreased facial nerve conduction velocity and abnormal blink reflex. Three children with complete recovery had disturbed blink reflex only with normal nerve conduction. Brain imaging studies as well as laboratory work-up were non-contributory in all cases. CONCLUSION: The frequency of recurrent facial nerve palsy in children was similar to that in adults. The most significant factors in the evaluation of recurrent facial nerve palsy are medical history and physical findings at diagnosis and after short follow-up. In our patients, electrophysiological studies did not have either clinical or prognostic significance. The rate of full clinical recovery is about 70%, lower than in Bell palsy.

The paediatrician and the rabbi.

OBJECTIVES: During recent decades, rabbis in Israel have been playing an increasing role in the consultation of patients or their families on medical issues. The study was performed to determine the attitude of physicians to rabbinical consultation by parents of sick children for purposes of basic medical decision making. DESIGN AND SETTING: A questionnaire was prepared which contained questions regarding physicians' reactions to specific medical situations as well as their demographic data. The study participants included all the available physicians who were employed in the study period at one tertiary medical centre in Israel, which is not associated with any religious organisation. The questionnaire was presented personally to all of the physicians who were available for the study. RESULTS: Between 63% and 77% of the respondents were accepting of rabbinical consultation in regard to medical decisions. Nevertheless, in cases of divergence from accepted medical practice and in emergencies, almost all stated they would take measures to resist the rabbi's advice. This attitude did not correlate with the physician's age, religious status or experience in medicine. CONCLUSIONS: Israeli physicians respect rabbis' suggestions in the area of medical decision making, though they would not let a rabbi's advice interfere with their decisions if they believed the rabbi's opinion went against medical need. In order to prevent an untoward effect of the rabbinical involvement in medicine, rules should be set to establish norms for rabbi-physician collaboration.

Pediatric journals on the Internet.

UNLABELLED: The objective of this study was to evaluate the structure and contents of the websites of the major journals in general pediatrics. A comprehensive search of the Internet was carried out to identify all pediatric journals in English that are listed in the Scientific Citation Index. Websites of 11 journals in general pediatrics were found, and their Web pages were systematically compared. Two of the appraised websites provided free on-line access to the full journal text, seven had on-line abstracts, and all provided the table of contents. The contents and abstracts covered varying periods, mostly just a few years back. Most of the journals offered easy search and other navigational options, but only a few allowed electronic submission of manuscripts. CONCLUSION: We conclude that in the era of immense growth and dissemination of information, aimed either at medical professionals or their patients, general pediatrics journals are lagging behind. The pediatrician today remains dependent on hospital libraries and their limited and sometimes cumbersome capabilities. Only a few of the pediatric journal websites can serve as an efficient on-line source for updating the knowledge. Further developments in the future should allow for improved services.
