TOC Summary: Rickettsiae closely related to the scrub typhus agent are present in the Western Hemisphere.

TART in prepubertal males with classic CAH could be found during childhood. We also report differences in markers of gonadal function in a subgroup of patients, especially in those with inadequate control.

Fever persisting at day 4 of admission, together with AMC < or =100 and CRP > or =90 significantly increased the risk for IFD in children with cancer.

Cervical cancer mortality in Chile is four times higher than in developed countries. We compared the accuracy of human papillomavirus (HPV) DNA testing and conventional Papanicolaou (Pap) testing to detect prevalent precancerous and cancerous lesions in the routine clinical practice of the public health system. Women aged 25 years and older residing in the area covered by three primary care centers of Santiago, Chile, were invited to participate. Eligible women received both HPV DNA (Hybrid Capture 2) and Pap testing. Women positive by either test (Pap: ASCUS1, HC2: RLU/CO !1.0) underwent colposcopy and biopsy, as did a sample of double-negative women with an abnormal cervix at visual inspection or with risk factors for cervical lesions. Crude and verification bias-corrected sensitivities and specificities were estimated. In total, 8,265 women (98.8% of eligible) had complete screening results. Of these, 10.7% were HPV positive, 1.7% were Pap positive and 1.1% were positive by both tests. In all, 931 (11.3%) women were screen-positive, of whom 94.3% attended colposcopy. Additionally, 295 control women were invited for colposcopy, of whom 78% attended. In all, 42 CIN2, 45 CIN3 and 9 cancers were identified. Verification bias-corrected sensitivity for CIN21 (95% confidence interval) was 92.7% (84.4-96.8) for HPV and 22.1% (16.4-29.2) for Pap; corresponding specificities were 92.0% (91.4-92.6) and 98.9% (98.7-99.0). In conclusion, in routine clinical practice in a developing country, HPV testing was four times more sensitive for CIN21 than Pap testing, identifying three times more CIN21 lesions; HPV testing was easily implemented in our established cervical cancer prevention program.In Chile, cervical cancer causes the death of more than 600 women each year, mainly of low socio-economic level, and is the second most common cause of cancer death for Chilean women aged 20-44 years.1 The current country's mortality rate of 7.6/100,000 is four times higher than that of developed countries.2,3 These facts emphasize the need to improve the effectiveness and equitability of the national cervical cancer prevention program.There is ample evidence that the detection of human papillomavirus (HPV) DNA in cervical samples has a higher sensitivity for cervical cancer and precancerous lesions than the Papanicolaou (Pap) test, 4 and high-quality HPV tests are routinely used in prevention programs in some developed countries. Although there have been many studies of implementing de novo screening methods in developing countries, [5][6][7][8]

Trichophyton mentagrophytes var. erinacei is the most common dermatophyte isolated in hedgehogs. Usually T. mentagrophytes var. erinacei infection manifests as an extremely inflammatory and pruritic eruption that is confined to the site of contact with the hedgehog. Although the identification of T. mentagrophytes by traditional methods is possible, identification by ITS region analysis is a fast, simple, and increasingly available method. The increasing frequency of the practice of keeping exotic animals as pets has resulted in the emergence of several zoonotic diseases that can potentially be transmitted to humans.

Analysis by PCR was more sensitive in detecting Y chromosome sequences than conventional karyotype. The presence of Y material was not associated with virilization. We confirmed the association of Y fragments and gonadoblastoma at an early age.

BackgroundWe previously conducted a population-based screening trial of high-risk human papillomavirus (hrHPV) testing and conventional cytology, demonstrating higher sensitivity (92.7 % vs 22.1 % for CIN2+) but lower positive predictive value (10.5 % vs 23.9 %) of hrHPV testing. Here we report the performance of HPV16/18 genotyping to triage the hrHPV positive participants.MethodsWomen aged 25 years and older received hrHPV (Hybrid Capture 2) and Papanicolaou testing; positives by either test underwent colposcopy and directed biopsy, as did a sample of double-negatives. hrHPV positive women were reflex-tested with HPV16/18 genotyping (Digene HPV Genotyping PS Test).ResultsAmong the 8,265 participants, 10.7 % were hrHPV positive, 1.7 % had ASCUS+ cytology, 1.2 % had CIN2+; 776 (88 %) hrHPV positive women had complete results, of whom 38.8 % were positive for HPV16 (24.0 %), HPV18 (9.7 %) or both (5.1 %). CIN2+ prevalence in HPV16/18 positive women (16.3 %, 95 % CI 12.3-20.9) was twice that of HPV16/18 negative women (8.0 %, 95 % CI 5.7-10.8). HPV16/18 genotyping identified 40.5 % of CIN2, 66.7 % of CIN3 and 75.0 % of cancers. Compared to hrHPV screening alone, HPV16/18 triage significantly reduced the referral rate (10.7 % vs 3.7 %) and the number of colposcopies required to detect one CIN2+ (9 vs 6). When HPV16/18 negative women with baseline ASCUS+ cytology were also colposcopied, an additional 14 % of CIN2+ was identified; referral increased slightly to 4.2 %.ConclusionsHPV16/18 triage effectively stratified hrHPV positive women by their risk of high-grade lesions. HPV16/18 positive women must be referred immediately; referral could be deferred in HPV16/18 negative women given the slower progression of non-HPV16/18 lesions, however, they will require active follow-up.
