UNIVERSITAS PRETORIENSIS SIGILLUM o16 POWER POINT PRESENTATION16.1 Preparing your PresentationWrite your text as you intend presenting it.Time yourself (lock your room).Now reduce all sentences to facts.Sentence structure now incomplete no articles; verbs can be omitted.Once your text is concentrated, start with slide show.

UNIVERSITAS PRETORIENSIS SIGILLUM o16.2 Preparing your SlidesUse graphs and diagrams instead of long explanations (add images).Use graphs rather than numbers.Use a sans serif font (Arial, Century Gothic, Univers).Transitions and animations can be distracting.Keep style format uniform.Ensure sufficient contrast in slides.Avoid transitions; use animation.

Use of animationThis is the first bullet. Do not animate.This is the second. Drag the mouse over the text and click Animations. Then click on Fade.Repeat for every step or bullet.

Mobile Phones andHuman HealthIntroductionBackgroundHypothesisScientific BasisEpidemiological MethodsCauses of InconsistencyConclusion

Layout of PresentationIntroductionBackgroundHypothesisScientific BasisEpidemiological MethodsCauses of InconsistencyA Conclusion will be presented

This is bad if read out word by wordAn hypothesis that mobile phone use can cause serious health problems has been proposed.Various approaches that attempt to prove that hypothesis have been proposed and carried out.To date no definitive answer on the health effects of mobile phone use have been reached.

BackgroundOccurrence of increased cancer amongst radio amateurs noted (1988)Due to concerns over 50 Hz fields and leukemia in early 1980s, questions asked about cellular phones.Studies in Denmark and Sweden because of early phasing in of technology.

HypothesisNo hypothesis based on scientific deduction from premises.Hypothesis based on suspected epidemiological coincidence of cancerous diseases.Increased use of mobile phones can cause a variety of cancers, amongst othersBrain tumours: glioma, meningiomaAcoustic neuromas

Scientific basisRadio Frequency power cannot cause cellular breakdown non-ionising.Damage to the brain tissue can result if temperature rises by more than 0.5Blood-Brain Barrier prevents toxins from entering brain.Possible mechanism is destruction of BBB.

Epidemiological MethodsCohort studies are retrospective, evaluates total population.Case-control studies compare group of cases with disease to control group.Questionnaires have disadvantage of poor memory, bias, Combined studies: meta-analysis.

Positive AssociationSignificant leakage of albumin through the blood-brain barrier of rats induction? (Salford).Weak association between gliomas and analog cellular phones (Anssi).Slight increase in risk observed with increasing duration of exposure merits further research with larger sample sizes.

Positive AssociationUse for 10 years give consistent pattern increased risk acoustic neuroma & glioma - ipselateral (Hardell).

Age-adjusted incidence of tumors

No CausalityData do not support hypothesis that mobile phone use related to increased risk of glioma or meningioma (Ahlbom).No significant association was found across categories with duration of use, years since first use (Lakhola).

ValidityRandom errorSystematic errorBiasSelection biasConfoundingInformation bias

ConclusionSubstantial criticism on methodology of many epidemiological studies.INTERPHONE study: suggestions of increased risk of gloima at highest exposure levels; biases and error prevent causal interpretation.Inconclusive
