Breech presentation refers to the foetus in the longitudinal lie with the buttocks or lower extremity entering the pelvis first.

The current recommendation for the breech presentation at term includes offering external cephalic version (ECV) to those patients that meet criteria, and for those whom are not candidates or decline external cephalic version, a planned caesarean section for delivery sometime after 39 weeks.

Dermoid cysts and teratomas contain elements from multiple germ cell layers. They are often considered the same entity (even in medical texts) however a dermoid is composed only of dermal and epidermal elements. A teratoma has mesodermal and endodermal elements Mature teratomas are composed of well-differentiated derivations from at least 2/3 germ cell layers (i.e. ectoderm, mesoderm, and endoderm). They contain developmentally mature skin complete with hair follicles, sweat glands, sometimes hair, and sometimes sebum, blood, fat, bone, nails, teeth, eyes, cartilage, and thyroid tissue.

This patient who is at her 29 weeks of pregnancy, presented with sudden gush of clear fluid and Speculum examination has confirmed premature rupture of membrane (PROM).

Approximately, 50% of PROM progress to labour within 24 hours and in the remaining, 80% within seven days. The most important next step of management in this case is transferring this patient to tertiary care hospital as soon as possible. It is equally important to give corticosteroid therapy, like Betamethasone, if delivery prior to 34 weeks is likely to occur, as it will help in fetal lung maturity.

Cardiotocography (CTG) is usually not available in general practice settings and it can be done only while in the hospital. If CTG shows any abnormality or if there is any presence of infection it is better to induce labor.

Salbutamol and nifedipine are of no use in this case, as the patient is not in labour and does not require tocolytics.

This patient presenting with oligohydramnios in her third trimester and had reported an episode of sudden gush of fluid secondary to ruptured membrane which she had mistaken to be “urinary incontinence”.  Hence, the most likely cause of oligohydramnios in this patient will be premature preterm rupture of membrane (PPROM).

An amniotic fluid volume which is less than expected for gestational age is called as Oligohydramnios and is typically diagnosed by ultrasound examination. This condition can be qualitatively described as reduced amniotic fluid volume and quantitatively as amniotic fluid index ≤5 cm or a single deepest pocket <2 cm. Oligohydramnios either can be idiopathic or may have a maternal, fetal or placental cause. Fetal prognosis in this case depends on several factors like the underlying cause, the severity of loss ie. reduced versus no amniotic fluid state and the gestational age at which oligohydramnios occurred. As an adequate volume of amniotic fluid is critical for the normal fetal movements, for fetal lung development and for cushioning the fetus and umbilical cord from uterine compression, so pregnancies complicated with oligohydramnios are at higher risk for fetal deformation, pulmonary hypoplasia and umbilical cord compression.
Oligohydramnios is also associated with an increased risk for fetal or neonatal death, which can either be related to the underlying cause of reduction in amniotic fluid volume or due to the sequelae caused due to reduced amniotic fluid volume. The amniotic fluid volume reflects the balance between fluid production and movement of fluid out of the amniotic sac and the most common mechanisms behind oligohydramnios are fetal oliguria/anuria or fluid loss due to rupture of membranes; also reduction in the amount of lung fluid or increased swallowing do not play major roles in this. Idiopathic cases as in idiopathic oligohydramnios, may be due to alterations in the expression of water pores like aquaporin 1 and aquaporin 3, present in fetal membranes and placenta.

Causes of oligohydramnios
a) Maternal causes includes:
– Medical or obstetric conditions associated with uteroplacental insufficiency like preeclampsia, chronic hypertension, collagen vascular disease, nephropathy, thrombophilia.
– Intake of medications like angiotensin converting enzyme inhibitors, prostaglandin synthetase inhibitors, trastuzumab.
b) Placental causes are:
– Abruption of placenta
– Twin polyhydramnios-oligohydramnios sequence which is the Twin to twin transfusion
– Placental thrombosis or infarction
c) Fetal cases leading to oligohydramnios are:
– Chromosomal abnormalities
– Congenital abnormalities which are associated with impaired urine production
– Growth restriction
– Demise
– Post-term pregnancy
– Ruptured fetal membranes
– Infections
– Idiopathic causes

During First trimester: Etiology of oligohydramnios during the first trimester is often unclear. As the gestational sac fluid is primarily derived from the fetal surface of the placenta via transamniotic flow from the maternal compartment and secretions from the surface of the body of the embryo reduced amniotic fluid prior to 10 weeks of gestation is rare.

During Second trimester: Fetal urine begins to enter the amniotic sac and fetus begins to swallow amniotic fluid by the beginning of second trimester, therefore, during this period any disorders related to the renal/urinary system of the fetus begins to play a prominent role in the etiology of oligohydramnios. Some of such anomalies include intrinsic renal disorders like cystic renal disease and obstructive lesions of the lower urinary tract like posterior urethral valves or urethral atresia. Other common causes of oligohydramnios in the second trimester are maternal and placental factors and traumatic or nontraumatic rupture of the fetal membranes.

During Third trimester: Oligohydramnios which is first diagnosed in the third trimester is often associated with PPROM or with conditions such as preeclampsia or other maternal vascular diseases leading to uteroplacental insufficiency. Oligohydramnios frequently accompanies fetal growth restriction as a result of uteroplacental insufficiency.

Lichen Sclerosis is a destructive inflammatory condition that effects the anogenital region of women. It effects around 1 in 300 women. It destroys the subdermal layers of the skin resulting in hyalinization of the skin leading to parchment paper appearance of the skin. It is associated with vulval cancer and it is estimated that the risk of developing vulval cancer after lichen sclerosis is around 3-5%.

Rubella typically has an incubation period of around 14 days. Rage 12-23 days

Clinical decision making which contraceptive regimen is optimal for an individual woman with epilepsy is one of the most challenging tasks when taking care of women with epilepsy. The bidirectional interactive potential of antiepileptic drugs (AEDs) and hormonal contraceptives needs to be taken into account. Enzyme inducing (EI)-AEDs may reduce the contraceptive efficacy of hormonal contraceptives.

If combined oral contraceptives (COCs) are used in combination with EI-AEDs, it is recommended to choose a COC containing a high progestin dose, well above the dose needed to inhibit ovulation, and to take the COC pill continuously (“long cycle therapy”). But even with the continuous intake of a COC containing a higher progestin dose contraceptive safety cannot be guaranteed, thus additional contraceptive protection may be recommended.

Progestin-only pills (POPs) are likely to be ineffective, if used in combination with EI-AEDs.

Subdermal progestogen implants are not recommended in patients on EI-AEDs, because of published high failure rates.

Depot medroxyprogesterone-acetate (MPA) injections appear to be effective, however they may not be first choice due to serious side effects (delayed return to fertility, impaired bone health).

The use of intrauterine devices is an alternative method of contraception in the majority of women, with the advantage of no relevant drug–drug interactions. The levonorgestrel intrauterine system (IUS) appears to be effective, even in women taking EI-AEDs. Likelihood of serious side effects is low in the IUS users.

Normally, there will be a slight raise in prolactin level throughout pregnancy even despite estrogen stimulating and progesterone inhibiting prolactin secretion.

Serum alkaline phosphatase levels will be increased in pregnancy due to placental ALP.

During the first trimester of pregnancy there is a physiological mechanism by hCG causing cross-stimulation of the TSH receptors and as a result of this the concentration of thyroid stimulating hormone (TSH) normally decreases. During second trimester TSH concentration will again return back to its pre-pregnancy levels and then rises slightly by the third trimester. However, most of the changes still occur within the normal non-pregnant range, and the serum free T3 and T4 concentrations remain unchanged throughout pregnancy. But the total concentrations, which include both free and protein-bound fractions, elevates significantly due to an increase in the circulating binding globulins.

Iron binding capacity reflects transferrin, a protein used for iron transportation, which is a globulin found in the beta band on electrophoresis. To counteract the reduction of plasma iron during pregnancy both transferrin and iron binding capacity are elevated during this period.

When compared to the non-pregnant level, cortisol levels are been elevated up to three times than normal.

Urethral syndrome is characterized by dysuria and pyuria in the presence of a negative culture for uropathogens. Frequency and urgency are often absent. The infecting organism is typically Chlamydia trachomatis although other organisms such as Urea plasma urealyticum and Mycoplasma species may be involve- Effective medication choices include doxycycline, ofloxacin, levofloxacin, and macrolides such as erythromycin and azithromycin.

-Amoxicillin
lavulanate  and cephalexin  are incorrect. These would cover gram-positive bacteria but it would not cover gram-negative bacteria nor bacteria without a cell wall, which are the most common causes of this condition.
– Metronidazole is best for treating anaerobic infections and protozoa such as trichomonas vaginalis, it would not be the best for treating this condition, given the most likely causes.
-Pyridium is a phenazopyridine often used to alleviate the pain, irritation, discomfort, or urgency caused by urinary tract infections. While it would be beneficial for symptomatic relief, it is unlikely to completely resolve this patient’s condition, given her recent history.

Basophils are granulocytic white blood cells. They express IgE antibody on their surface and react to release prostaglandins and leukotrienes to mediate an inflammatory, allergic reaction.
Blood Cell Lifespans:
Red Blood Cells 120 days
Platelets 5-9 days
White blood cells 2-5 days

Neutrophils (up to 5 days)
Basophils (2 to 3 days)
Eosinophils (2 to 5 days)
Monocytes (1 to 5 days)
Lymphocytes (variable)

During follicular phase, there is an increase in gonadotrophin hormones and a proliferation of the endometrium occurs. The duration of the cycle depends upon the overall length of the menstrual cycle. The progesterone levels are increased in the luteal phase and not in follicular phase.

A cervical screening test was performed on this patient, and the result revealed the presence of the Human Papilloma Virus Type non-16/18. Reflex liquid base cytology was conducted, but no further abnormalities were seen. In this case, the patient should be offered a 12-month repeat cervical screening cytology. If the patient’s repeated cervical screening cytology after 12 months revealed LSIL, she should be referred for a colposcopy.
If HPV is discovered at 12 months, regardless of the LBC result, some women may be at higher risk of having high-grade abnormalities and should be referred to colposcopy. These include:
– women 2 or more years overdue for screening at the time of the initial screen
– women who identify as being of Aboriginal or Torres Strait Islander
– women aged 50 years or older.

Summary of recommended actions based on the level of risk
Intermediate danger:
– HPV non-16/18 positive, intermediate risk (with negative or low-grade cytology)
If feasible, repeat the HPV test after 12 months.
A three-to-six-month delay would be acceptable. Delays of longer than six months are discouraged.
Follow up HPV test – HPV non 16/18 (possible high grade cytology or high-grade squamous lesion (HSIL) – Treated as Higher risk.

High-risk:
HPV non-16/18 positive on follow-up HPV test (with negative or low-grade cytology)
Refer to an expert right away for further investigation.

If your patient is: 2 years or more past due for screening at the time of the initial screening, and identifies as Aboriginal or Torres Strait Islander aged 50 or older, they may be at higher risk and should be referred to a professional at once for additional evaluation.

HPV 16/18 positive with any of the following non–16/18 positive: a glandular anomaly in high-grade cytology high-grade squamous lesion (HSIL) cancer. Refer to an expert right away for further investigation.

Currently, several colposcopy facilities are experiencing strong demand and extended wait times. If you are concerned that your patient will be delayed, you should call the specialist or clinic to which your patient has been referred.
On the Cure Test Pathway, wherever possible, continue testing as planned. A woman who has been treated for HSIL (CIN2/3) should have a 12-month follow-up co-test and annual tests after that. She can resume standard 5-yearly screening after receiving two consecutive negative co-tests.

About 97% of the testosterone that is secreted loosely binds to the SHBG and circulates in the blood for several hours in this bound state until it is transported to the target organs.

The most suitable step would be to wait for spontaneous onset of labour. This woman would be able to deliver vaginally in 3 situations. The first would be if the foetus is estimated to weigh less than 3800g (first child weight 3800g). Another would be if the foetus is in a frank or complete breech presentation and lastly if the rate of labour progress is satisfactory and breech extraction is unnecessary. RCOG (Royal College of Obstetricians & Gynaecologists) guidelines recommends that women should be informed that elective Caesarean section for the delivery of a breech baby would have a lower risk of perinatal mortality than a planned vaginal delivery. This is because with an elective Caesarean section, we would be able to avoid stillbirth following 39 weeks of gestation as well as intrapartum and vaginal breech delivery risks. The ideal mode of delivery of a breech foetus when labour starts or at least close to term is a Caesarean section as the risks towards the foetus would be significantly increased in a vaginal delivery. The obstetrician is responsible to ensure that there are no other abnormalities that could complicate this even further such as footling presentation, low estimated birth weight (less than 10th centile), hyperextended neck on ultrasound, evidence of fetal distress and high estimated birth weight (>3.8kg). Provided that there is a normal progression of events, fetal risks during both labour and delivery should be low if such factors are absent. Hence, it is right to await the onset of labour to occur spontaneously in this case. In order to exclude a knee presentation with fetal head extension or a footling breech, ultrasound examination has to be done. These are linked to a high fetal risk if the mother attempts vaginal delivery. X-ray pelvimetry is advisable but is not essential in fetal size assessment since its accuracy is roughly 20%. In this case, it is not indicated since there is evidence that her pelvis is of adequate size as she had already delivered a 3.9kg baby prior. It is best to avoid induction of labour in breech cases for numerous reasons (need for augmentation, cord prolapse).

Leiomyomas uterine (fibroids)
Clinical features:
Menses that are heavy and last a long time, symptoms of pressure, pelvic discomfort, constipation, frequency of urination, complications during pregnancy, fertility problems, loss of pregnancy, premature birth, uterus enlargement and irregularity

Workup:
Ultrasound

Treatment:
Asymptomatic: monitoring
Surgical intervention, hormonal contraception

This patient has uterine leiomyomata, or fibroids, which are benign smooth muscle (myometrial) tumours that are very prevalent in adult women (up to 25%). These tumours can expand the endometrium’s surface area, the uterus’ overall size and thickness, and compress adjacent structures; nevertheless, some individuals have no symptoms and are identified by chance during a physical examination or imaging (as in this patient’s CT scan after a car accident).
Heavy, prolonged menses are among the indications for uterine leiomyomata treatment (particularly if associated with anaemia).
Pelvic discomfort that persists (e.g., dyspareunia).
Symptoms in abundance (e.g., pelvic pressure, hydronephrosis, constipation).
Recurrent miscarriages.
Medical or surgical treatment options are available for patients with these clinical characteristics (e.g., myomectomy).

This woman had mild menses and no pelvic discomfort or mass symptoms while having many big intramural and pedunculated leiomyomata (e.g., no ureter compression). There is no need for extra treatment in persons with asymptomatic fibroids. Only observation and reassurance are required.
In the treatment of symptomatic fibroids, a combination of oral contraceptive pills and progestin-containing intrauterine devices can be utilised, although they are not required in the management of asymptomatic fibroids. Furthermore, this patient has a minimal risk of unwanted pregnancy (e.g., monogamous, same-sex relationship), and the hazards of these contraceptives (e.g., venous thromboembolism, uterine perforation) outweigh the benefits.

GnRH agonist therapy (e.g., leuprolide) is a treatment for symptomatic uterine fibroids that works by inhibiting pulsatile FSH and LH production in the hypothalamus, lowering oestrogen levels. Low oestrogen levels cause a temporary reduction in leiomyoma size, which helps with heavy menses and bulky symptoms. Because long-term usage of GnRH agonists is linked to an increased risk of osteoporotic fractures, they are only administered preoperatively.

Tranexamic acid is a nonhormonal medicinal medication that reduces heavy menstrual bleeding by preventing fibrin breakdown (i.e., an antifibrinolytic drug). This patient’s menses are light.
Uterine leiomyomata (fibroids) are benign myometrial tumours that can produce a range of symptoms but are often identified by chance. Heavy menstrual blood, pelvic pain, and bulk symptoms are all indications for treatment. Patients with asymptomatic fibroids merely need to be monitored and reassured.

Tissues with actively dividing cells, such as bone marrow and gastrointestinal mucosa, are particularly sensitive to ionising radiation. Lymphocyte depletion is the most sensitive marker of bone marrow injury, and after exposure to
a fatal dose, marrow aplasia is a common cause of death. The gonads are highly radiosensitive and radiation may result in temporary or permanent sterility. Stochastic (chance) effects occur with increasing probability
as the dose of radiation increases. Carcinogenesis represents a stochastic effect. With acute exposures, leukaemias may arise after an interval of around 2–5 years and solid tumours after an interval of about 10–20 years. Moist skin desquamation can be an acute reaction to both radio and chemotherapy whereas fibrosis and lymphoedema are late complications.

Under the influence of prolactin, oestrogen and progesterone and human placental lactogen (hPL), the mammary epithelium proliferates but remains presecretory during mammogenesis. Lactogenesis is inhibited by high circulating levels of progesterone and oestrogen which block cortisol binding sites. Cortisol would have otherwise have worked synergistically with prolactin in milk production. A sharp decrease in progesterone levels after delivery allows prolactin and oxytocin to stimulate milk production and the milk ejection reflex in response to suckling. Prolactin continues to maintain milk production in galactopoiesis.

In normal pregnancy the levels of hCG doubles after every 48-72 hours but in case of ectopic pregnancy the levels of hCG are lower than the normal. It is produced by the placenta and its main role is nourishment of the egg after implantation. Its levels reached a peak at 8-10 weeks of pregnancy and after that the levels decreases for the remainder of pregnancy. In hydatiform mole and trophoblastic diseases its the main hormone for diagnosis of the disease because the levels are highly elevated.

Osteogenesis imperfect is an autosomal dominant condition. All the rest of the options are autosomal recessive conditions.

Chickenpox or varicella is a contagious disease caused by the varicella-zoster virus (VZV). The virus is responsible for chickenpox (usually primary infection in non-immune hosts) and herpes zoster or shingles (following reactivation of latent infection). Chickenpox results in a skin rash that forms small, itchy blisters, which scabs over. It typically starts on the chest, back, and face then spreads. It is accompanied by fever, fatigue, pharyngitis, and headaches which usually last five to seven days. Complications include pneumonia, brain inflammation, and bacterial skin infections. The disease is more severe in adults than in children.

Primary varicella infection during pregnancy can also affect the foetus, who may present later with chickenpox. In pregnant women, antibodies produced as a result of immunization or previous infection are transferred via the placenta to the foetus. Varicella infection in pregnant women could spread via the placenta and infect the foetus. If infection occurs during the first 28 weeks of pregnancy, congenital varicella syndrome may develop. Effects on the foetus can include underdeveloped toes and fingers, structural eye damage, neurological disorder, and anal and bladder malformation.

Prenatal diagnosis of fetal varicella can be performed using ultrasound, though a delay of 5 weeks following primary maternal infection is advised.

Antivirals are typically indicated in adults, including pregnant women because this group is more prone to complications.
