A Case Report of Water Hemlock Poisoning
Introduction: Water hemlock poisoning is an uncommon cause of seizures, gastrointestinal upset, and renal failure. This poisoning occurs infrequency and is likely to go unrecognized without a proper history and consideration in the differential diagnosis.
Clinical Findings: A 23-year-old male with an unremarkable past medical history presented to the emergency department after being found unresponsive at a farm where he was employed. He had several tonic-clonic seizures en route. Initial evaluation was unremarkable and included toxicology screening, lumbar puncture, and brain imaging.
Main diagnoses, therapeutics, interventions, and outcomes: The patient was treated with broad-spectrum antibiotics and antivirals with a suspected diagnosis of viral encephalitis. Over the next several days of hospitalization, he developed severe rhabdomyolysis and renal failure, and dialysis was anticipated. Upon further investigation, it was discovered that on the morning of his presentation, the patient made himself tea with a plant he had dug up while fly fishing. He believed the plant was valerian root after researching it on the Internet. The plant was later identified as water hemlock. With supportive care, the patient’s mentation cleared, and his renal failure spontaneously resolved without the need for dialysis. His symptoms fully resolved, and he was discharged home.
Conclusions: This case illustrates an unusual etiology of seizures and rhabdomyolysis and the need for careful history taking. The interest in nontraditional medicine and the ease of finding amateur foraging data on the internet have greatly raised the possibility of accidental toxic ingestions
Principles for sustainable riverfront development for Malaysia
River and water are important resources for human life, environment and national development. In
Malaysia, the importance of rivers as the focal point of the city was established from early times of
civilisation and remains forever. Population and economic growth, urbanisation and increased technology
have transformed many Malaysian river systems from water industries into non water industries. Due to
these changes, the function of the riverfront areas have also changed and the current pattern of riverfront
development in Malaysia now focus more on mixed-use development and recreation. Presently, numbers of
riverfront development projects were developed in Malaysia for recreation, residential, and mixed-use.
Unfortunately, in most cases, the developments identified are not successful whereby, having cost effects
more than economic value. For example, increases in water pollution indexes and rates of juvenile
problems. The focus of this study was to examine waterfront development in Malaysia as well as to identify
the attributes of waterfront development, in order to develop guidelines for waterfront development. The
findings of this research were based on interviews conducted with Government officers, Property
developers, and the Waterfront community from three case study areas (qualitative phase), and from
questionnaires mailed and e-mailed to property development companies listed under Bursa Malaysia
(quantitative phase). The findings identified 18 attributes to be used in assisting developers when
undertaking waterfront projects in the future. The attributes identified were then recommended to be used
as guidelines of best practices of riverfront development in Malaysia
Crystallization at Solvent Interfaces Enables Access to a Variety of Cocrystal Polymorphs and Hydrates
A crystal
growth technique, interfacial cocrystallization, is demonstrated
to be a simple and effective method for preparing multicomponent crystal
forms. The technique is based on the generation of a liquid–liquid
interface between two immiscible solutions of cocrystal-forming compounds,
and its utility is demonstrated through the preparation of polymorphs
and hydrates of caffeine cocrystals, involving three different hydroxy-2-naphthoic
acids, including the formation of some with unexpected compositions

The influence of soil communities on the temperature sensitivity of soil respiration
Soil respiration represents a major carbon flux between terrestrial ecosystems and the atmosphere, and is expected to accelerate under climate warming. Despite its importance in climate change forecasts, however, our understanding of the effects of temperature on soil respiration (RS) is incomplete. Using a metabolic ecology approach we link soil biota metabolism, community composition and heterotrophic activity, to predict RS rates across five biomes. We find that accounting for the ecological mechanisms underpinning decomposition processes predicts climatological RS variations observed in an independent dataset (n = 312). The importance of community composition is evident because without it RS is substantially underestimated. With increasing temperature, we predict a latitudinal increase in RS temperature sensitivity, with Q10 values ranging between 2.33 ±0.01 in tropical forests to 2.72 ±0.03 in tundra. This global trend has been widely observed, but has not previously been linked to soil communities
