50

What is a threatened miscarriage?

This is when there is bleeding from the gravid uterus before 24 weeks gestation, when there is a viable fetus and no evidence of cervical dilation. The uterus may remain viable and the pregnancy continues without any further problems. The cervix is closed in speculum examination.

51

What is an inevitable miscarriage?

when there is dilation of the cervix

52

What is an incomplete miscarriage?

When there is only partial expulsion of the products of conception

53

What is a complete miscarriage?

Complete expulsion of the products of conception

54

What is a septic miscarriage?

Following incomplete abortion there is always a risk of ascending infection into the uterus which can spread through the pelvis and is known as septic abortion

55

What is the definition of a missed miscarriage?

When the fetus has died but the uterus has made no attempt to expel the products of conception. No symptoms or could have bleeding vaginally. Gestational sac seen on scan. No clear fetus or fetal pole with no fetal heart seen in the gestational sac.

56

What is the aetiology of spontaneous miscarriage?

Abnormal conceptus

      chromosomal, genetic, structural - It is estimated that 50% of spontaneous miscarriages may be due to abnormal chromosomes.

Uterine abnormality

      congenital, fibroids - Congenital uterine abnormalities result from a failure of normal fusion of the mullerian ducts - incidence of spontaneous miscarriage in this group is estimated to be double that of the normal population. Submucosal fibroids are especially associated with spontaneous miscarriage due to distortion of the uterine cavity.

Cervical incompetence

       Primary, secondary - The cervix opens prematurely with absent or minimal uterine activity and the pregnancy is expelled. Trauma to the cervix can be an important aetiological factor such as cone biopsy treatment?

Maternal

         increasing age, diabetes - Hormonal imbalances are also said to be a cause of spontaneous miscarriage. The corpus luteum is essential for  ensuring the survival of the pregnancy during the first 8 weeks of term. If the corpus luteum is to be removed surgically then abortion will usually occur within 7 days. In threatened miscarriage, those that continue to have inevitable miscarriages will have lower levels of progesterone than those that continue pregnancies to term.

Maternal causes of spontaneous miscarriage can include SLE, thyroid disease, acute maternal infection such as appendicitis, pyelitis. Maternal infection causes general toxic illness with high temperature that can stimulate uterine activity and loss of pregnancy.

59

What is a molar pregnancy?

Molar pregnancy is an abnormal form of pregnancy in which a non-viable fertilized egg implants in the uterus and will fail to come to term.

A molar pregnancy is a gestational trophoblastic disease which grows into a mass in the uterus that has swollen chorionic villi. These villi grow in clusters that resemble grapes. A molar pregnancy can develop when fertilized egg had not contained an original maternal nucleus. The products of conception may or may not contain fetal tissue. It is characterized by the presence of a hydatidiform mole. Molar pregnancies are categorized as partial moles or complete moles, with the word mole, being used to denote simply a clump of growing tissue, or a growth.

60

What is the difference between a complete and an incomplete hydatiform mole?

Complete = single sperm fertalises enucleate egg, this means that the moile only contains paternal DNA. There are no fetal cells and there is a risk of GTN (gestational trophoblastic neoplasia) - this includes invasive mole, choriocarcinoma and placental site trophoblastic tumour. 

Partial = One normal egg cell fertilised by two normal sperm cells, usually triploid. Some fetal cells are evident such as amnion and RBC,s there isn't really an association with choriocarcinoma.

132

Here is management of diabetes in pregnanct women

Important to note that there is increase in insulin requirement, early induction of labour and early feeding of baby to reduce neonatal hypoglycaemia

 

before pregnancy, to prevent malformations: make sure blood sugars are 4-7mmol/L pre-conception and HbA1c <6,5% (<48mmol/L), folic acid 5mg, dietary advice, retinal and renal assessement 

during pregnancy, to prevent metabolic complications: increase insulin, can continue oral anti-diabetic agents, should be aware of hypos risk, watch for ketonuria/infections, repeat retinal assessement 28 and 34w, watch fetal growth, observe mother for PET, oral hypoglyacemics are usually avoided (according to book page 259)

giving birth: induction of labout at 38-39 weeks is the norm, consider C-section if significant fetal macrosomia, maintain blood glucose in labour with insulin-dextrose insulin infusion, continuous CTG fetal monitoring in labour, early feeding of baby to reduce neonatal hypoglycaemia, switch back to pre-pregnancy regimen for insulin post delivery 

133

How can you interpret the progesterone withdrawal test?

So if there is anovulation then - progesterone given and then removed, bleeding 2-7 days later. This is dependant on sufficient estradiol concentration in the serum.

 

If no bleeding = Low serum estradiol, hypothalamic pituitary axis dysfunction, non-reactive endometrium, outflow tract abnormality such as cervical stenosis.

 

If it is not an outflow tract obstruction then it is likely to be due to low oestrogen. Withdrawal bleeding occurs after removal of oestrogen / progesterone therapy.

Transverse - The break is in a straight line across the bone.

Spiral - The break spirals around the bone; common in a twisting injury.

Oblique - Diagonal break across the bone.

Compression - The bone is crushed, causing the broken bone to be wider or flatter in appearance.

Comminuted - The break is in three or more pieces and fragments are present at the fracture site.

before starting treatments that may have a rapid adverse effect on bone density (for example, sex hormone deprivation for treatment for breast or prostate cancer).

in people aged under 40 years who have a major risk factor, such as history of multiple fragility fracture, major osteoporotic fracture, or current or recent use of high-dose oral or high-dose systemic glucocorticoids (more than 7.5 mg prednisolone or equivalent per day for 3 months or longer).

393

What is the management of osteoporosis?

Minimise risk factors

Ensure good calcium and Vitamin D status

Falls prevention strategies

Medications - hormone replacement therapy

 

Side effects of HRT - increased risk of blood clots increased risk of breast cancer with extended use into late 50's/early 60's

Increased risk of heart disease and stroke if used after large gap from menopause.

 

Selective oestrogen receptor modulator raloxifene - only effective in preventing vertebral body fractures - doesn't affect hip fractures.

 

Negative effects of SERMS- hot flushes if taken close to menopause, increased clotting risks, lack of protection at hip site

 

 

Bisphosphonates are the main Rx option

 

Oral Bisphosphonates generally the first line of treatment

Adequate Renal function required

Adequate Calcium and Vitamin D status

Good Dental Health and Hygiene advised

Notify dentist on Bisphosphonates

Encourage regular check ups / well fitting dentures

 

Alendronate - this is one of the popular bisphosphonates used to treat osteoporosis

 

 

Side effects of bisphosphonates -

Oesophagitis

Iritis/uveitis

Not safe when eGFR<30 mls/min

ONJ

Atypical femoral shaft fractures

Drug Holiday for 1-2 years

Usually after 10 years Oral Bisphosphonates

 

Bisphosphonates can also cause osteonecrosis of the jaw. - very rare

 

Even though you increase the chance of atypical femoral shaft fracture - you are still 200 times more likely to break your hip by osteoporosis than bisphosphonates

 

Denosumab - this is a monoclonal antibody against RANKL

 

The RANK L ligand is responsible for regulating osteoclast activity

 

Denosumab requires a subcutaneous injection every 6 months - safer in patients with significant renal impairment than bisphosphonates.

 

Osteoclasts do not get the signal to resporb bone

There is no negative feedback signal to osteoblasts continue to lay down bone

 

Side effects of Denosumab:

Allergy / rash

Symptomatic hypocalcaemia if given when vitamin D deplete

ONJ?

Atypical femoral shaft fracture?

 

Teriparatide - intermittent human parathyroid hormone - this is the first portion of parathyroid hormone - makes osteoblasts lay down bone - only anabolic bone treatment (only treatment that actually aids in the laying down of bone

What is the pathophysiology of plantar fasciitis/fasciosis?

chronic degenerative change, fibroblast hypertrophy, absence inflammatory cells, disorganised and dysfunctional blood vessels and collagen, avascularity, can’t make extra cellular matrix required for repair and re-modelling -> (microtears?)

504

What are the risk factors for plantar fasciitis/fasciosis?

athletes associated with high intensity or rapid increase in training, running with poorly padded shoes or hard surfaces, obesity, occupations involving prolonged standing, foot/lower limb rotational deformities, tight gastro-soleus complex 

505

What tendon dysfunction might cause medial or lateral pain and cause medial heel to move inwards and downwards?

Tibialis posterior tendon dysfunction

506

What is the sign for tibialis posterior tendon dysfunction?

clinical diagnosis (double & single heel raise; heel should swing for valgus to varus as heel rises)

507

What are the investigations for tibialis posterior tendon dysfunction?

Clinical

MRI to assess tendon

508

What is the management of tibialis posterior tendon dysfunction?

orthoses or surgery (reconstruction of tendon (tendon transfer), triple fusion (subtalar, talonavicular and calcaneocuboid)

509

What is the managment of diabetc foot ulcer?

prevention

 

modify the main detriments to healing (diabetic control, smoking, vascular supply, external pressure (splints/shoes/weight bearing), internal pressure (deformity), infection, nutrition

 

surgical: improve vascular supply, debride ulcers and get deep samples for microbiology, correct any deformity to offload area, amputation

510

What is the name of the foot deformity assocaited with diabetic foot?

Charco neuropathy

511

What is the managment for charcot foot?

prevention

 

immobilisation/non-weight bearing until acute fragmentation resolved

 

correct deformity (deformity leads to ulceration leads to infection leads to amputation)

512

What is the pathophyiology of charcot neuropathy?

2 theories:

neurotraumatic (lack of proprioception and protective pain sensation)

 

neurovascular (abnormal autonomic nervous system results in increased vascular supply and bone resorption

 

characterised by rapid bone destruction occuring in 3 stages (fragmentation, coalescence, remodelling)

513

What is management of RA?

effective suppression of inflammation will improve symptoms and prevent joint damage and disability

 

analgesics

 

NSAIDs: 

 

disease modifying anti-rheumatic drugs (DMARD): methotrexate, sulfasalazine, hydroxychloroquine, leflunomide, penicillamine, gold

 

biologics:

TNF alpha inhibitor (Anakinra), anti B cell therapies (CD20, Rituximab), anti T cell therapies (Abatacept), IL-6 inhibitors (Tocilizumab)

 

corticosteroids: (short term benefit vs long term toxicity) rarely appropriate as single drug therapy

 

patient education: encourage to alternate rest with exercise

514

What is presentation of RA?

Morning stiffness, improves with use
Bilateral symptoms
Systemic upset

Joint swelling (joints are swollen and warm, limitation of movement

Lymphadenopathy

Splenomegaly

 

 

Systemic - fatigue/lethargy, weight loss, anaemia

swollen, painful joints in hands and feet

stiffness worse in the morning

gradually gets worse with larger joints becoming involved

presentation usually insidiously develops over a few months

positive 'squeeze test' - discomfort on squeezing across the metacarpal or metatarsal joints


Swan neck and boutonnière deformities are late features of rheumatoid arthritis and unlikely to be present in a recently diagnosed patient.

 

 

515

What is the diagnostic criteria for RA?

diagnosis criteria: need 4 out of 7 (RF RISES)

Rheumatoid factor

Finger/hand joint involvement

Rheumatoid nodules

Involvement of 3 or more joints

Stiffness - early morning

Erosions/decalcification on XR

Symmetrical arthritis

516

What are the bloods seen on RA?

bloods: ESR + CRP (degree of synovial inflammation), anaemia of chronic disease, low albumin (correlates directly with disease severity), neutropenia (in Felty’s syndrome)

517

What are immunology findings in RA?

immunology:

rheumatoid factor IgG, IgM

anti-cyclic citrullinated antibodies (anti CCP, ACPA)

ANA(?)

518

What are the complications of RA?

A wide variety of extra-articular complications occur in patients with rheumatoid arthritis (RA):

respiratory: pulmonary fibrosis, pleural effusion, pulmonary nodules, bronchiolitis obliterans, methotrexate pneumonitis, pleurisy

ocular: keratoconjunctivitis sicca (most common), episcleritis, scleritis, corneal ulceration, keratitis, steroid-induced cataracts, chloroquine retinopathy

osteoporosis

ischaemic heart disease: RA carries a similar risk to type 2 diabetes mellitus

increased risk of infections

depression


Less common

Felty's syndrome (RA + splenomegaly + low white cell count)

amyloidosis

519

520

What are normal hormonal changes for the start of labour?

Progesterone decreases whilst oxytocin and prostaglandins increase to allow for labour to initiate

521

What happens during stage 1 of labour?

Latent stage - intermittent, often irregular or painful contractions which bring about some cervical effacement and dilatation up to 4 cm.

 

Established stage - Contractions become regular and painful. Result in progressive effacement and cervical dilation from 4 cm

 

 

Complete when cervix is fully dilated (10 cm)

 

Primagravida = 8 hours (usually not longer than 18 hours)

Multigravida = 5 hours (unlikely to last more than 12 hours)

 

Anticipated progress 0.5-1.0 cm per hour

522

What is stage 2 of labour?

Full cervical dilation to the birth of the baby

Passive second stage of labour - Full dilation of the cervix with or without expulsive contractions

Active second stage - Presenting part is visible, expulsive contractions with full dilatation of the cervix, active maternal effort following confirmation of full dilatation of the cervix in the absence of expulsive contractions.

 

Primagravida = birth would be expected within two hours of active second stage commencing

Multigravida = 1 hour

523

What is the 3rd stage of labour?

Birth of the baby to the expulsion of the placenta and membranes

 

Active management management includes:

Routine use of uterotonic drugs

Deferred clamping and cutting of the cord

Controlled cord traction after signs of separation of the placenta.

Physiological management includes:

No routine use of uterotonic drugs

No clamping of the cord until pulsation has stopped

Delivery of the placenta by maternal effort.

 

 

Prolonged in:

Active management over 30 mins

Physiological management after 60 mins

524

How do we monitor pregnancy?

Monitoring of liquor (colour, smell and volume)

Auscultation of fetal heart (doppler, pinards or with CTG) - intermittent monitoring is undertaken every 15 minutes in the first stage of labour and every 5 minutes in the second stage. 

Palpation of uterine muscle contractions. 

525

What are different types of vertex presentation?

Vertex

Sinciput (forehead)

Brow

Face Chin

526

What is the most common presentation of a baby?

LOA 

527

Which bone in normal labour is the presenting part?

Anterior parietal 

528

What are the mechanisms of labour?

Descent

Flexion

Internal rotation of the head

Crowning and extension of the head

Restitution

Internal rotation of the shoulders

External rotation of the head

Lateral flexion

529

What are possible analgesias in pregnancy?

Analgesia in labour

Breathing, massage, TENS, paracetamol and dihydrocodeine

TENS = transcutaneous electrical nerve stimulation

Water

Entonox (inhalational nitrous oxide and oxygen)

Opioids (morphine, diamorphine, pethidine)

Remifentanil patient controlled analgesia

Epidural

Consider maternal position and mobility as means of reducing pain and facilitating progress in labour

Evidence demonstrates that continuous midwifery care reduces the need for analgesia and increased likelihood of SVD and maternal satisfaction with birth experience (RCM, 2012: Bohren et al 2017).
