Postcoital bleeding is a predictor for cervical dysplasia.

BACKGROUND: Postcoital bleeding (PCB) is a common gynecological symptom that may cause concern among both patients and physicians. Current literature is inconclusive regarding management recommendations. OBJECTIVE: To identify risk-factors for dysplasia/cancer among patients presenting post-coital bleeding (PCB). METHODS: Using large health maintenance organization (HMO) database, all women reporting PCB in 2012-2015 were identified. PCB patient records in a single colposcopy center were reviewed. Age, marital status, ethnicity, gravidity, parity, BMI, smoking, PAP smear result (within 1 year of PCB presentation), colposcopy and biopsy results were recorded. Cases were matched by age and socio-economic enumeration area to controls accessing primary care clinics for routine care. RESULTS: Yearly incidence of PCB ranged from 400 to 900 per 100,000 women; highest among patients aged 26-30 years. Among the sample of 411 PCB cases with colposcopy, 201 (48.9%) had directed biopsy. Biopsy results included 68 cervicitis (33.8%), 61 koilocytosis/CIN 1/condyloma (30.3%), 44 normal tissue (21.9%), 25 cervical polyp (12.4%), 2 CIN 2/3 (1%) and 1 carcinoma (0.5%). Positive predictive value for koilocytosis/CIN 1 or higher pathology was 15.6% (64/411) and 0.7% for CIN 2 or higher grade pathology (3/411). In conditional logistic regression, multiparty was a protective factor: OR 0.39 (95% CI 0.22-0.88, P = 0.02), while pathological PAP smear was a related risk-factor: OR 3.3 (95% CI 1.31-8.35, P = 0.01). When compared to controls, PCB patients were significantly (P = 0.04) more likely to present CIN 1 or higher grade pathology (OR 1.82, 95% CI 1.02-3.33). CONCLUSIONS: Study results indicate that PCB may require colposcopy, especially for nulliparous women with an abnormal PAP smear.

Effectiveness of rotavirus vaccines for prevention of rotavirus gastroenteritis-associated hospitalizations in Israel: a case-control study.

The association between rotavirus gastroenteritis (RVGE)-associated hospitalization and rotavirus vaccine receipt was examined, and vaccine effectiveness was estimated in a case-control study conducted between 11/2007 and 12/2009 among Israeli children age eligible for rotavirus vaccination. Cases (n=111) were hospitalized children with diarrhea testing positive for rotavirus by immunochromatography. Controls (n=216) were hospitalized children with diarrhea testing negative for rotavirus. Among controls 36 (16.7%) children were vaccinated against rotavirus compared with two children (1.8%) among cases (p < 0.001). Rotavirus immunization was associated with lower risk of RVGE-associated hospitalization; adjusted OR 0.106 (95% CI 0.024, 0.481), yielding a vaccine effectiveness of 89.4% (95% CI 51.9%, 97.6%) in preventing hospitalization. These data demonstrate high effectiveness of rotavirus vaccines in a high income country.

Incidence, characteristics, and economic burden of rotavirus gastroenteritis associated with hospitalization of israeli children <5 years of age, 2007-2008.

BACKGROUND: Limited data exist on the epidemiology and burden of rotavirus gastroenteritis in Israel. Objectives. Our objective was to examine the incidence, characteristics, and economic burden of rotavirus gastroenteritis associated with hospitalization of children <5 years of age in Israel. METHODS: A prospective study was initiated in pediatric wards at 3 hospitals in northern Israel. Presence of rotavirus in stool specimens was detected by immunochromatography, and G and P genotypes were determined by reverse-transcriptase polymerase chain reaction. Demographic data, clinical manifestations, and expenditures related to a child's illness were studied using parental interviews. RESULTS: From November 2007 through October 2008, 472 children hospitalized with gastroenteritis were enrolled in the study. Rotavirus gastroenteritis was diagnosed in 39.1% of children, with a peak identification rate during November 2007-January 2008 (62.5%-71.0%). Most cases of rotavirus gastroenteritis (87.2%) occurred in children <2 years of age. In infections with 1 rotavirus genotype, G1P[8] was the most frequently detected (49.1%), followed by G1P[4] (11.1%) and G9P[8] (9.3%). Mixed rotavirus isolates were identified in 28.9% of the children. The estimated incidence of primary hospitalizations for rotavirus gastroenteritis among children aged 0-5 years was 5.7 hospitalizations per 1000 children per year (95% confidence interval, 5.1-6.3 hospitalizations per 1000 children per year), resulting in an estimate of 4099 annual national hospitalizations (95% confidence interval, 3668-4531 hospitalizations per year). This figure represents approximately 6.5% of the total annual hospitalizations among Israeli children <5 years of age. The annual calculated cost of hospitalizations for rotavirus gastroenteritis was US $7,680,444, including US $4,578,489 (59.6%) in direct costs to the health care system and US $3,101,955 in overall household costs. CONCLUSIONS: Our findings are important for decision making regarding implementation and evaluation of a routine immunization program against rotavirus gastroenteritis.

Universal versus selective iron supplementation for infants and the risk of unintentional poisoning in young children: a comparative study of two populations.

BACKGROUND: Iron continues to be a common cause of poisoning in young children, in part due to its widespread use and easy accessibility. OBJECTIVE: To determine differences in the epidemiology and outcome of unintentional iron ingestion by young children in populations practicing selective (eg, US) versus universal (eg, Israel) iron supplementation to infants. METHODS: All cases of unintentional iron ingestion in children younger than 7 years in a one year period were identified through the poison control center databases of 2 sites (Illinois and Israel). Parameters compared include patient sex and age; type, form, and dose of iron preparation; circumstances and clinical manifestations; management; and outcome. RESULTS: A total of 602 children were identified: 459 in Illinois and 143 in Israel. The majority of Illinois children ingested multivitamin preparations (94%), whereas Israeli children ingested single-ingredient iron preparations (78%) (p < 0.001). Iron doses ingested were higher in Israel (median 14.5 vs 6.6 mg/kg; p < 0.001) but remained within the nontoxic range for most children. No deaths or severe poisonings were reported, and 93% of children in both groups were asymptomatic. The majority of ingestions in both locations were due to unintentional self-ingestion. However, parental miscalculation occurred more frequently in Israel (16%) than in Illinois (1%). CONCLUSIONS: Universal iron supplementation to infants was not associated with a negative impact on the outcome of pediatric unintentional ingestions. Low-dose exposures were safely managed by on-site observation.
