It has been suggested that genes related to Amerindian ancestry account for the high prevalence of gallstone disease (GD) observed in Mexican-Americans. The HLA-B39 is an allele found in higher frequency in Amerindians whereas HLA-B15 is rarely found. The aim of this study was to test the hypothesis that gallstone susceptibility genes are more prevalent in Mexicans with recent Amerindian ancestry.', 'We carried out a prospective case-controlled study. Subjects were divided into those who had stones visible on gallbladder ultrasound (cases), and those whose ultrasounds were negative for gallstones (controls). Body mass index (BMI) was calculated, and serum lipids and lipoprotein, and glucose levels were measured. Class I HLA (HLA-B) typing was performed by PCR amplification of genomic DNA.', 'Of the 1,101 subjects, 146 were classified as subjects with GD (cases) and 955 as subjects without GD (controls). Mean age of the cases was 53.5 +/- 12.5 yr versus 44.78 +/- 12.0 yr for the controls, p= 0.001. A family history of GD was observed in 48% of the cases versus 28.4% of the controls, p= 0.001. HLA-B39 was more frequently increased in GD subjects (0.162), compared with controls (0.063), p= 0.008. The odds ratio of having HLA-B39 was 2.8 and 95% (CI 95%= 1.3-6.3) for GD; HLA-B15 was more frequently increased in controls than in cases.

To assess the effect of newborn circumcision on the incidence and medical costs of urinary tract infection (UTI) during the first year of life for patients in a large health maintenance organization.', 'Kaiser Permanente Medical Care Program of Northern California (KPNC).', 'The population consisted of members of KPNC. The study group consisted of a cohort of 28 812 infants delivered during 1996 at KPNC hospitals; of the 14 893 male infants in the group, 9668 (64.9%) were circumcised. A second cohort of 20 587 infants born in 1997 and monitored for 12 months was analyzed to determine incidence rates.', 'Retrospective study of all infants consecutively delivered at 12 facilities.', 'Diagnosis of UTI was determined from the KPNC computerized database using the International Classification of Diseases, Ninth Revision code for inpatients and KPNC Outpatient Summary Clinical Record codes for outpatients. A sample of 52 patient charts was reviewed to confirm the International Classification of Diseases, Ninth Revision and KPNC Outpatient Summary Clinical Record codes and provide additional data.', 'Infants <1 year old who were born in 1996 had 446 UTIs (292 in females; 154 in males); 132 (86%) of the UTIs in males occurred in uncircumcised boys. The mean total cost of managing UTI was 2 times as high in males ($1111) as in females ($542). This higher total cost reflected the higher rate of hospital admission in uncircumcised males with UTIs (27.3%) compared with females (7.5%); mean age at hospitalization for UTI was 2.5 months old for uncircumcised boys and 6.5 months old for girls. In 1996, total cost of managing UTI in uncircumcised males ($155 628) was 10 times higher than for circumcised males ($15 466) despite the fact that uncircumcised males made up only 35.1% of the male patient base in 1996, reflecting the more frequent occurrence of UTI in uncircumcised males (132 episodes) than in circumcised males (22 episodes), and the larger number of hospital admissions in uncircumcised males (38) than in circumcised males (4). The incidence of UTI in the first year of life was 1:47 (2.15%) in uncircumcised males, 1:455 (.22%) in circumcised males, and 1:49 (2. 05%) in females. The odds ratio of UTI in uncircumcised:circumcised males was 9.1:1.

Due to recent war situation in neighboring country we have witnessed large number of victims with post-traumatic false (pseudo) aneurysms of head and neck in roadside bomb blast victims in Pakistan. Thus through this observational retrospective study we aim to share our experience of managing these patients.', "5 years patients' case records, from June 2008-June 2013, were reviewed from the hospital's records. 14 cases of roadside bomb blast victims, developing false aneurysms of major or minor vessels of head and neck, were studied. We excluded the post-traumatic pseudoaneurysms involving other sites and vessels of the body. We observed the mechanism, the duration of presentation, symptoms/signs, vessels involved, complications and the management done.", 'All 14 cases presented with a localized pulsatile swelling with tenderness in the course of a known artery and with an overlying entry site wound from bomb blast sharp nails. Men were affected more as compared to women. All (14) cases had 2-12 weeks of duration between the injury and presentation. Temporal artery (4) was involved in most cases followed by common carotid artery (3). Open surgery was treatment of choice in 12 (85.7%) of cases; however 2 (14.3%) patients had endovascular intervention to correct the pathology. Post-operatively all patients recovered completely, without any major or minor complications.
