Femoral triangle

It is located anteromedially in upper part of thigh.
Boundaries are
inguinal ligament superiorly,
medial border of sartorious laterally,
lateral border of adductor longus medially.
The apex continues into adductor canal.
The base is formed by the adductor longus, pectineus and iliopsoas.
The floor is formed by fascia lata pierced in the region of saphenous opening to form cribiform fascia.

Femoral canal

In the human anatomy of the leg, the femoral sheath has three compartments.
The lateral compartment contains the femoral artery, the intermediate  femoral vein and the medial the femoral canal.
The femoral canal contains efferent lymphatic vessels and a lymph node ( Cloquet).
It is 2 cm long. Its shape is conical.
Its opening is femoral ring.
The boundaries are
inguinal ligament anteriorly,
the pectial ligament posteriorly,
the lacunar ligament medially,
the femoral vein laterally.

Cephalhaematoma versus subgaleal haemorrhage

Cephalhaematoma is a subperiosteal haemorrhage secondary to the
rupture of blood vessels. Its boundaries are limited by the individual
bones. In most cases, there is probably a hairline fracture of the
underlying cranial bone, which may be difficult to demonstrate but is
unimportant since it affects only the outer table of the skull. There
is usually no brain damage. A large amount of blood may be accumulated
and blood transfusion may be required. A large cephalhaematoma may be
associated with neonatal jaundice and anaemia.
The usual cause of cephalhaematoma are prolonged second stage of
labour or instrumental delivery particularly ventouse.
During resolution, there may be a hard swelling which takes several
months to disappear. In some cases, calcification of the swelling
leaving a relatively softer centre mimic depressed fractures.
Cephalhaematoma can be differentiated from the caput succedaneum ,
which is a soft swelling due to the edema of the skin presenting at
the cervix and it crosses the suture line. Caphelhaematoma is limited
to the one side of suture line.
Cephalhaematoma must also be distinguished from another scalp bleeding
called subaponeurotic haemorrhage (also called subgaleal haemorrhage),
which is bleeding between the scalp and skull bone (above the
periosteum).
Subgaleal haemorrhage is rare after normal vertex vaginal. It can be
found one in 1000 babies delivered by ventouse. The baby can become
shocked and mortality rate can be as high as 20%. The clue to the
diagnosis is a boggy swelling of the scalp that crosses the suture
line.

Common forms of Birth trauma to the baby

1. caput succedaneum
2. cephalhaematoma
3. chignon from vacuum extraction
4. brachial plexus injury (Erb's palsy)
5. facial palsy
6. subconjunctival haemorrhage
7. subgeleal (subapponeurotic haemorrhage)

MIN(Multicentric intraepithelial neoplasia)

Intraepithelial neoplastic changes seen at more than one site in lower
genital tract.
The sites involve are the cervix, vagina, vulva, perineum, and anal canal.
The aetiology of MIN is the combination of HPV Infection and host immune
suppression of varying degrees.
MIN may be detected in a woman who has repeated abnormal smear despite
treatment for CIN, in a woman being examined for VIN, or an HIV positive
woman.
There are no guidelines for treating this disease. MIN must be treated in
large centres to concentrate experience and expertise.
Cases are complex and chronic. Some women have already undergone repeated
surgery over years.
Investigations must be individualized and may include multiple colposcopic
directed biopsies, HPV typing, HIV testing and test of T cell function.
Management aims to exclude invasive cancer, to control symptoms, and to
preserve anatomy and functional integrity where possible.
New immunomodulating therapies currently under investigations such as
therapeutic vaccination and imiquimod.

Polymorphic eruption of pregnancy

The commonest pregnancy specific dermatosis. Incidence is about 1 in 200-250 ie about 0.5%.

Occured in 3rd trimester, usually after 35 week's gestation.

More common in primiparous and multiple pregnancies.

Distributed over the abdomen along the striae (with umbilical sparing), with spread to thigh, buttock, under the breast and upper arms.

Pruritic, urticarial, plaques, rarely vesicles and target lesions

Histology shows epidermal/dermal oedema, perivascular infiltration, and patchy parakeratosis.

Resolve usually 2 weeks after delivery.

No effect on fetus.

Treatments include 1% menthol in acqueos cream, 1% hydrocortisone cream or oinment, sedative antihistamine. Systemic steroids are only occationally required for intractable cases.

Recurrence is uncommon.

Fwd: Dermatological Conditions in pregnancy: treatments to be avoided

Acitretin and terzarotene (retinoids used in Psoriasis)

Isotretinoin (retinoid used to treat severe acne)

Griseofulvin (antifungal)

Methotrexate (antimetabolites used in treatment of Psoriasis)

Tetracycline

Thalidomide (leprosy treatment)

Fitz-Hugh-Curits Syndrome

A rare complication of pelvic inflammatory disease.
Named after the two physicians, Thomas Fitz-Hugh, Jr and Arthur Hale Curtis.
Occur almost exclusively in female.
The major symptom, following an episode of PID, is an acute onset,
right upper quadrant abdominal pain aggravated by breathing, coughing
or movement.
The pain may be referred to right shoulder.
Violin string(adhesions between parietal peritoneum to liver) may be
seen by laparoscopy.
Treatment involves diagnosing and treating the underlying cause correctly.
The adhesiolysis may be performed laparoscopically.

Norplant: levonogestrel implants

Norplant system kits contain levonogestrel implants, a set of six flexible
closed capsules made of silicone rubber tubing. Each contains 36mg of
levonogestrel. Each capsule is 2.4 mm in diameters and 34mm in length.
Efficacy is 5 years.

The system releases 85mcg per day of levonogestrel, followed by 50mcg per
day by 9 month, 35mcg per day by 18 months and then further decline to
about 30 mcg per day.

Contraindications are
1. active thrombophlebitis or thromboembolic disorders
2. undiagnosed abnormal bleeding pre vagina
3. suspected pregnancy
4. active liver disease, benign or malignant liver tumour
5. known or suspected carcinoma of breast
6. history of idiopathic intracranial hypertension
7. hypersensitivity to levonogestrel or any other components of Norplant

Side effects are prolonged menstruation, irregular menstruation,
spotting, amenorrhoea, pain or itching near the implant site,
infection at implant site, difficulties in removal

Renal disease in pregnancy: chronic renal disease

Chronic renal disease is classifed as CKD 1-5 according to the severity.

Stage 1- GFR (ml/min/1.73m2) >90

Stage 2- GFR (ml/min/1.73m2) 60-80

Stage 3- GFR (ml/min/1.73m2) 30-59

Stage 4- GFR (ml/min/1.73m2) 15-29

Stage 5- GFR (ml/min/1.73m2) <15

Howevever, estimated GFR is not validated to use in pregnancy.
