Role of Human Papillomavirus Infection in Head and Neck Cancer in Italy: The HPV-AHEAD Study

Literature on the role of human papillomavirus (HPV) in head and neck cancer (HNC) in Italy is limited, especially for non-oropharyngeal tumours. Within the context of the HPV-AHEAD study, we aimed to assess the prognostic value of different tests or test algorithms judging HPV carcinogenicity in HNC and factors related to HPV positivity at the European Institute of Oncology. We conducted a retrospective cohort study (2000-2010) on a total of 696 primary HNC patients. Formalin-fixed, paraffin-embedded cancer tissues were studied. All HPV-DNA-positive and a random sample of HPV-DNA-negative cases were subjected to HPV-E6*I mRNA detection and p16INK4a staining. Multivariate models were used to assess for factors associated with HPV positivity and proportional hazards for survival and recurrence. The percentage of HPV-driven cases (considering HPV-E6*I mRNA positivity) was 1.8, 2.2, and 40.4% for oral cavity (OC), laryngeal (LC), and oropharyngeal (OPC) cases, respectively. The estimates were similar for HPV-DNA/p16INK4a double positivity. Being a non-smoker or former smoker or diagnosed at more recent calendar periods were associated with HPV-E6*I mRNA positivity only in OPC. Being younger was associated with HPV-E6*I mRNA positivity in LC. HPV-driven OPC, but not HPV-driven OC and LC, showed better 5 year overall and disease-free survival. Our data show that HPV prevalence in OPC was much higher than in OC and LC and observed to increase in most recent years. Moreover, HPV positivity conferred better prognosis only in OPC. Novel insights on the role of HPV in HNC in Italy are provided, with possible implications in the clinical management of these patients.

Transvaginal laparoscopy: A minimally invasive approach to obtain brush cytology of the Fallopian tube

OBJECTIVE

To evaluate in a prospective pilot study the feasibility of cytobrushing of the fimbrial end using a transvaginal endoscopic access.

STUDY DESIGN

Prospective feasibility study. The procedure was performed in a consecutive series of 15 infertile women referred for a transvaginal laparoscopy as part of their fertility investigation. Tubal cells were collected using a 5Fr cytobrush. Cytology and immunocytochemistry was done.

RESULTS

In all patients enough cell material was obtained for analysis, without traumatizing the fimbrial end. Specimens showed the presence of a sufficient amount of cells enabling standard cytologic examinations and immunocytochemistry (Ki 67, p53).

CONCLUSION

Fimbrial cytobrushing using the transvaginal approach is an easy and minimally invasive procedure. The easy accessibility of the fimbrial end and the distal ampullary part at TVL allows an accurate collection of tubal epithelial cells. In view of the recent data reporting the Fallopian tube and more specifically the fimbrial end as a possible origin of ovarian carcinoma, further research is needed to evaluate the potential of this technique as a possible screening method for patients at risk for ovarian cancer.

Schizophrenia among Surinamese in the Netherlands: high admission rates not explained by high emigration rates

BACKGROUND

A high risk of schizophrenia has been found among Caribbean immigrants in the Netherlands and Great Britain. One hypothesis to explain these findings is that patients with a diagnosis of schizophrenia or patients with symptoms of psychosis not specifically diagnosed, emigrate more than the general population. Such selection might account for high rates of Surinamese patients with a diagnosis of schizophrenia in Netherlands psychiatric hospitals. We examined this hypothesis.

METHODS

The files of patients with schizophrenia or patients suffering from unspecified psychosis were selected from the archives of the National Psychiatric Hospital in Surinam. These patients were traced to investigate patterns of emigration. Data from the Central Bureau for Statistics in the Netherlands and from the Central Population Bureau in Surinam provided the percentage of the general Surinamese population that emigrated to the Netherlands. The difference between the two percentages was evaluated using the chi-squared test. Using the same method the percentage of remigration from the Netherlands among Surinamese patients was compared with the percentage of remigration among the general Surinamese population.

RESULTS

Surinamese patients with schizophrenia or unspecified psychosis did not emigrate more frequently to the Netherlands compared with the general Surinamese population. They did remigrate significantly more frequently.

CONCLUSION

High migration rates do not explain the high hospital admission rates for schizophrenia among Surinamese in the Netherlands.

Lamellar bone formation in an atherosclerotic plaque of the carotid artery, with a review of histogenesis--a case report

Longer existing atherosclerotic lesions may contain calcifications; lamellar bone rarely develops within them. A 59-year-old man was referred with a progressive stroke. A high-grade stenosis of the left common carotid artery, formed by an ulcerating atherosclerotic plaque with a free-floating thrombus, was detected on angiography. An urgent endarterectomy was performed. Surprisingly this plaque contained pieces of lamellar bone, proved by histologic examination.

[High incidence of admissions for schizophrenia in Surinam patients in The Netherlands not caused by preferential immigration of (pre)schizophrenic patients]

OBJECTIVE

To answer the question whether positive selection of (pre)schizophrenic Surinams in Surinam before emigration to the Netherlands can explain the high admission rates for schizophrenia of Surinams in the Netherlands.

DESIGN

Retrospective research.

SETTING

's Lands Psychiatrisch Ziekenhuis (National Psychiatric Hospital) Paramaribo, Surinam (LPZ).

METHOD

The Netherlands Central Bureau of Statistics in Voorburg and the Central Registry Office in Paramaribo provided data on emigration to the Netherlands of the Surinam population and on remigration. Files of (pre)schizophrenic patients were selected from the records of LPZ. Subsequently, these patients were traced and their pattern of migration was studied. Using the chi 2 test the significance of observed differences was assessed.

RESULTS

Surinam (pre)schizophrenic patients did not emigrate more frequently to the Netherlands (6.3%) compared with the Surinam population in general (9.6%) and they remigrated more frequently to Surinam than the Surinams in general.

CONCLUSION

The positive selection hypothesis must be rejected.
