Gastrointestinal and hepatic manifestations in patients with generalised pustular psoriasis.

Generalised pustular psoriasis (GPP) is a rare and severe form of pustular psoriasis. It is defined by persisting or relapsing macroscopically visible sterile primary pustules occurring on non-acral skin and not within psoriasis plaques. Due to its rarity, there is a lack of randomised controlled trials on GPP and its associated gastrointestinal (GI) and liver disorders.

A computational and experimental study on acoustic pressure for ultrasonically formed oil-in-water emulsion.

In the field of ultrasonic emulsification, the formation and cavitation collapse is one major factor contributing to the formation of micro- and nano-sized emulsion droplets. In this work, a series of experiments were conducted to examine the effects of varying the ultrasonic horn's position to the sizes of emulsion droplets formed, in an attempt to compare the influence of the simulated acoustic pressure fields to the experimental results. Results showed that the intensity of the acoustic pressure played a vital role in the formation of smaller emulsion droplets.

Factors associated with false-positive mammography at first screen in an Asian population.

Introduction: False-positive recall is an issue in national screening programmes. The aim of this study is to investigate the recall rate at first screen and to identify potential predictors of false-positive recall in a multi-ethnic Asian population-based breast cancer screening programme.

Methods: Women aged 50-64 years attending screening mammography for the first time (n = 25,318) were included in this study.

Comparison of self-reported and register-based hospital medical data on comorbidities in women.

Breast cancer patients commonly present with comorbidities which are known to influence treatment decisions and survival. We aim to examine agreement between self-reported and register-based medical records (National Patient Register [NPR]). Ascertainment of nine conditions, using individually-linked data from 64,961 women enrolled in the Swedish KARolinska MAmmography Project for Risk Prediction of Breast Cancer (KARMA) study.

Determinants of breast size in Asian women.

Breast size as a risk factor of breast cancer has been studied extensively with inconclusive results. Here we examined the associations between breast size and breast cancer risk factors in 24,353 Asian women aged 50 to 64 years old enrolled in a nationwide mammography screening project conducted between October 1994 and February 1997. Information on demographic and reproductive factors was obtained via a questionnaire.

Undescended testis: Level of knowledge among potential referring health-care providers.

Aim: Studies report that most boys with undescended testis(UDT) are referred and operated beyond the recommended age of 1 year, possibly due to lack of awareness of treatment guidelines. We investigate the level of knowledge of UDT among potential referring health-care providers.

Method: We devised a survey on the clinical features and appropriate management of UDT.

Choice of primary health care source in an urbanized low-income community in Singapore: a mixed-methods study.

Introduction: Cost and misperceptions may discourage lower income Singaporeans from utilizing primary care. We investigated sources of primary care in a low-income Singaporean community in a mixed-methods study.

Methods: Residents of a low-income public rental flat neighbourhood were asked for sociodemographic details and preferred source of primary care relative to their higher income neighbours.
