First seizure in adults

A seizure is a transient occurrence of symptoms and/ or signs
 due to abnormal or synchronous neuronal activity in the brain 
( ILAE- International League Against Epilepsy )

Estimated that about 10 % of the population would experience atleast one epileptic seizure ( 3 % risk of epilepsy ) In US about 150 000 adults present each year with an unprovoked first seizure ( less than ½ have a readily apparent cause ) WHO estimates that about 70 % of people with epilepsy could live seizure free if properly diagnosed and treated Despite a decrease in disease burden ( from 1990-2016 ) epilepsy remains an important cause of disability and mortality ( Lancet -Neurology Feb 2019 ) UK active epilepsy estimate is 5-10 cases/1000 ( NICE )

International League Against Epilepsy-ILAE recommends making a diagnosis of epilepsy if the patient meets 
any 1 of the following conditions-Atleast 2 unprovoked seizures occurring 24 hrs apart 1 unprovoked seizure and a probability of further seizures over next 10 yrs is greater than 60 % Diagnosis of an epilepsy syndrome

Abnormal White Cell Count

White cell count abnormalities -assessment and evaluation

Monocytes- Constitute 3-8 % of the WCC Remain for a relatively short time in the circulation- after which they migrate to tissues and body cavities where they differentiate into macrophages They play a role in the inflammatory process ( members
of the mononuclear phagocyte system ) Good evidence exists to suggest that blood monocytes consist of several populations

Monocytosis –Associated with infection and inflammatory process Causes can be

○ Reactive monoytes
Infection- commonest cause
Inflammatory conditions as collagen vascular disease
chronic neutropenia
splenectomy
hemolytic anaemia
ITTP
Haematopoetic and non Haemtopoetic neoplasms

○ Neoplastic Monocytes
several primary hematologic neoplasms harbor neoplastic monocytes including CMML ,

Facial pain

Dental-Usually acute presentation Unilateral Located within the mouth but sometimes may be difficult to localise More than 90 % of orofacial pain is dental in origin Usually severe and throbbing in nature Made worse by hot or cold food or drink or by biting on the affected side

Dental caries- common cause which can progress to infection of the pulp ,

Macrocytosis-Evaluation

Macrocytosis –An increase in the mean cell volume ( MCV) above the normal range 

 Upper range may be quoted as 95-100 fl. Prevalence ranges from 1.7 % to 5 % Up to 60-80 % with macrocytosis may not have anaemia

Main causes- Alcohol B12 and or folate deficiency Medications Hypothyroidism ( rarely ) Bone marrow dysplasias Liver disease ( non-alcoholic ) Reticulocytosis Physiological ( neonates ,

Antibiotics- types based on mechanism of action

Inhibit cell wall synthesis- beta lactams.

Autism Spectrum Disorder-recognition and referral (Children )

Choosing an antidepressant

What is available and how does it work ? more than 
30 agents for unipolar depression

Most antidepressants work by enhancing the activity of monoamine neurotransmitters : serotonin , noradrenaline /norepinephrine or dopamine
 this is based on theories that implicate a deficiency of monoamines in the biology of depression popularly called the ”

Suicidal patient- assessment

Suicide can be defined as intentional self
 inflicted death

Suicide is a rare event Between 3.5 and 5 % of adults reported suicidal thoughts in the last year but only 0.5 % to 0.7 % actually made an attempt to end life ( US, UK date -BMJ 2017 ) In UK one in 5 adults has considered suicide at some time and one in 15 has attempted suicide Suicide prevention is a priority Approximately 6000 people take their own life each year in the UK ( NICE 2018 ) Patients would have sought help from health-care professions for eg
○ approximately 50 % of those who take their own lives will have seen a GP in the 3 months before death
○ 40 % in the month beforehand
○ around 20 % in the week before death
