- Methotrexate - not advised to get pregnant for 3 months.
Investigations for Molar pregnancy
- very high HCG
- uterus size greater than expected for gestational age
- US: snowstorm appearance
Length of UTI tx
- Pregnancy: 7 days -> trimetho (avoid 1st tri), nitrofu (avoid 3rd), amoxicillin, cefalexin
- LLTI Women: 3 days
- LLTI children: 3 days -> trimethoprim, nitrofurantoin, cephalosporin or amoxicillin
- UUTI children: 7-10 days -> cephalosporin or co-amoxiclav
(infants less than 3 months old should be referred immediately to a paediatrician)

Mx of pre-eclampsia
When pre-eclampsia is diagnosed, the general management is similar to gestational hypertension, except:
Scoring systems are used to determine whether to admit the woman (fullPIERS or PREP‑S)
- Blood pressure is monitored closely (at least every 48 hours)
- Urine dipstick testing is not routinely necessary (the diagnosis is already made)

Elevated oestrogen - COCP, ovulatory phase, pregnancy
What are the signs of Cushings triad that may occur with raised ICP
hypertension
bradycardia
irregular breathing
= is a late sign indicating impending brain herniation. Systolic hypertension occurs as a reflex to maintain cerebral perfusion pressure in the presence of raised intracranial pressure.

What is the sarnat scoring for HIE
Conscious level: Irritable/hyper alert (mild), Lethargy (Mod), Comatose/reduced (severe)
Tone: mildly abnormal (mild), hypo/hypertonic (mod), flaccid (severe)
Seizures: absent (mild), present (mod,severe)
Reflexes: Exaggerated (mild), Depressed (mod), absent (severe)
Mild: Resolves within 24 hr
Mod: Weeks. 40% risk of CP
Severe: 90% CP, 50% mortality.
Why is therapeutic cooling used in HIE
The intention of therapeutic hypothermia is to reduce the inflammation and neurone loss after the acute hypoxic injury. It reduces the risk of cerebral palsy, developmental delay, learning disability, blindness and death.
