UW 5 Flashcards
What are PCOS women deficient in
Progesterone
What is happening with estrogen in PCOS
Unopposed estrogen
Pt complains that straight lines appear wavy
Test?
Si/sx’s?
Macular Degeneration
- Grid test
- Driving and reading - activities affected
- Centrally located macula does fine visual acuity
When is enlarged blind spot seen
Papilledema
Karyotype and Presentation of Kallmann syndrome
Normal Karyotype: Female 46 XX, Male 46 XY
Normal genotype and internal productive organs
Absence of GnRH
- Females = Primary Amenorrhea, absent breasts
- Males = Eunuchoid, small external genitalia, absent secondary sexual traits - pubic hair, libido, deep voice
- Anosmia
Labs in Kallmann
Low FSH
Low LH
What is the cause of Secondary HTN in hyperthyroidism
Hyperdynamic state
- increased expression of myocardial sarcoplasmic reticulum Calcium dependent ATP
- Increased target organ sensitivity to endogenous catecholamines
Which kind of HTN in thyrotoxicosis
Predominantly Systolic
Hypothyroidism induced HTN
What kind and MOA
Diastolic
Increased SVR
Pathophys of thyroid level changes in pregnancy
- hCG stimulates TSH receptor
- Increased estrogen causes increase in production of TBG = increased TBG-bound T3 and T4, so total T3 and T4 are high
- SO increase in TBG, total T3, T4
Normal TSH, free T4, T3
Free air under diaphragm
Perforation
Porcelain Gallbladder
Presentation
TX
Calcium-laden GB Bluish/brittle Chronic Cholecystitis RUQ pain, mass TX: Cholecystecomy to prevent GB Cancer = Adeno
Gallstone ileus
pathophys
DX
TX
Large gallstones cause fistula formation bt GB and small intestine. Gallstone enters and obstructs intestine
DX: Presence of air in biliary tract
TX: Surgery
TX for TTP
Emergent Plasmapheresis to remove autoabs and replace deficient enzymes
TX for hypercalcemia
Symptomatic moderate and severe > 12
- IV Saline Hydration
- Calcitonin
During fasting, what happens to glycogen levels
Drop in first 12 hours
GN kicks in, and after 24 hrs - main source of glucose
Main substrates for GN
- Gluconeogenic amino acids - Alanine is main one
- Lactate
- Glycerol-3-Phosphate - intermediate break down of adipose
Alanine is converted to?
Pyruvate in GN
Lactate is converted to?
Pyruvate in GN
From anaerobic glycolysis
Older children w intussusception
Etiology
TX
Pathological lead point
Meckel’s diverticulum MCC in GIT
TX: Surgical resection
MC malignancy of thyroid gland
Papillary thyroid cancer
- Best prognosis
Thyroid cancer w worst prognosis
Anaplastic
Thyroid cancer from parafollicular C cells
Assn’s?
Medullary
- MEN 2a and 2b
Central scotoma + afferent pupillary defect + changes in color perception + decreased visual acuity
Optic Neuritis
Optic Neuritis Presentation
Ages 20-45 Females > Color perception changes Rapid impairment of vision MS
Presentation of Anterior Uveitis
Eye - painful and red
Blurring of vision
Keratic precipitates
Open angle Glaucoma Presentation
Gradual loss of peripheral vision
Tunnel vision
Cupping of optic disc
Osteomalacia
Etiology
Defective bone mineralization of organic bone matrix
MCC Vit D deficiency
causes decreased intestinal calcium and phosphorus absorption w secondary hyperparathyroidism
Others: Malabsorption, Celiac sprue
Labs of Osteomalacia
Hypophosphatemia
Hypocalcemia/Normal Ca
High Alk Phosp
Etiology of GVHD
Host major and minor HLA Ag recognition by DONOR T cells and CMI
Graft rejection
Mediated by HOST T cells
Labs in premature ovarian failure
Low estrogen
High FSH, LH
FSH > LH
Rubella Triad
Leukocoria
PDA
Hearing Loss
Congenital Toxoplasma Triad
Chorioretinitis
Intracranial calcifications
Hydrocephalus
Congenital Syphilis Presentation
Cataracts
Senso Hearing loss
Risk factors for polyp progressing to malignancy (colon)
Villous adenoma
Sessile adenoma
> 2.5 cm
Which type of polyp is non neoplastic and what is management
Hyperplastic
No further workup
Test of choice for esophageal perforation
Water-soluble contrast esophagram
Esophageal Perforation/Rupture Presentation
Worsening of condition after endoscopy
Radiographic findings - pleural effusion (L), pneumomediastinum, Pneumothorax
Beck’s Triad
Infants?
Distant Heart sounds
Distended jugular veins
(Scalp veins in infants)
HypoTN
Immediate postpartum, normal findings
Low grade fever
Leukocytosis
Lochia rubra, serossa, alba
Not foul smelling
MC adverse rxn of blood trasfusion 1-6 hours
Febrile nonhemolytic transfusion
- Fever
- Chills
- Malaise
Prevention of febrile nonhemolytic rxn
Leukoreduction of donor blood - residual plasma and/or leukocyte debris remains in red cell concentrate which release cytokines during storage
Urinary Cyanide test
Presence of cysteine
Think cystinuria
Hep C patients being considered for TX - management
LIver BX - best clinical predictor of disease progression
Assesses response to TX
Newly diagnosed Hep C patients
Assess for antiviral tx to delay progression w Liver BX
