Temporal trends and clinical characteristics of spontaneous intracerebral haemorrhage in the Waikato region of New Zealand: a hospital-based analysis.

Aims: To determine the incidence, and any change in incidence, of spontaneous intracerebral haemorrhage (ICH) detected in the hospitals of the Waikato region of New Zealand (NZ) between 1999 and 2008. To analyse clinical and patient parameters, and to correlate these with outcome.

Methods: A retrospective analysis was performed on patients presenting to Waikato and Thames Hospitals with ICH during the study period.

Urban rickettsiosis in the Waikato region of New Zealand.

Murine typhus is the only endemic rickettsia that has been shown to cause human disease in New Zealand (NZ). We present a case report of a rickettsial infection in the Waikato region which was not typical for murine typhus. We outline the features which made this case unusual, and discuss the diagnostic uncertainty in assessing rickettsial disease.

Convergent flash localization near saccades without equivalent "compression" of perceived separation.

Visual space is sometimes said to be "compressed" before saccadic eye movements. The most central evidence for this hypothesis is a converging pattern of localization errors on single flashes presented close to saccade time under certain conditions. An intuitive version of the compression hypothesis predicts that the reported distance between simultaneous, spatially separated presaccadic flashes should contract in the same way as their individual locations.

How does the nature of the steric stabilizer affect the pickering emulsifier performance of lightly cross-linked, acid-swellable poly(2-vinylpyridine) latexes?

A near-monodisperse styrene-functionalized poly[2-(dimethylamino)ethyl methacrylate] (PDMA) macromonomer was evaluated as a reactive steric stabilizer for the preparation of poly(2-vinylpyridine (P2VP) latexes via emulsion polymerization. The solution pH was shown to be a critical parameter for successful syntheses: stable latexes with minimal coagulum were only obtained at (or above) neutral pH. The presence of the grafted PDMA stabilizer in a near-monodisperse P2VP latex of 280 nm diameter was indicated by FT-IR spectroscopy and quantified at 6.

Rat-bite fever: a cautionary tale.

We present the first ever report of streptobacillary rat-bite fever in New Zealand. The patient was a young man who was admitted with systemic sepsis. He presented with a high fever, hypotension, and tender axillary lymphadenopathy.

Portal venous thrombophlebitis in a case of perforated appendicitis: lessons from a case.

Portal and mesenteric pyelephlebitis is a rarely recognised condition associated with a high morbidity. It usually develops secondary to infection in the drainage area of the portal venous system. We report a case of perforated acute appendicitis complicated by superior mesenteric venous pyelephlebitis and thrombocytopaenia.

Efficient synthesis of sterically stabilized pH-responsive microgels of controllable particle diameter by emulsion polymerization.

Emulsion polymerization of 2-vinylpyridine (2VP) in the presence of divinylbenzene (DVB) cross-linker, a cationic surfactant, and a hydrophilic macromonomer, monomethoxy-capped poly(ethylene glycol) methacrylate (PEGMA), at around neutral pH and 60 degrees C afforded near-monodisperse, sterically stabilized latexes at approximately 10% solids. Judicious selection of the synthesis parameters enabled the mean latex diameter to be varied over an unusually wide range for one-shot batch syntheses. Scanning electron microscopy studies confirmed near-monodisperse spherical morphologies, with mean weight-average particle diameters ranging from 370 to 970 nm depending on the initiator, polymeric stabilizer, and surfactant concentrations.

From our perspective: consumer researchers speak abut their experience in a community mental health research project.

People who have experienced the mental health system were hired and trained as researchers in a community mental health research project. Throughout the course of the project, these consumer researchers reflected on what they learned about their research experience. This article is a window into this learning process and offers an opportunity to see research through the eyes of consumer researchers.
