chronic bronchitis complications
increased risk of infections and for pulmonate, clamp down to shunt from O2 low region and move it to other areas, but if its all over from disease all over can create increased RH work which led to right heart hypertrophy and failure.
emphysema presentation
destroy alveolar sacs from exchange so increased collapse because cant have enough elastic roil to stay open. It is dyspnea, airway collapse of small ones, purse lips for increased back pressure to prevent trapping, and pink offer ,weight loss from increased breathing work ,and wide chest from increased chest pull out
what is emphysema pathophysiology of smoking caused

what do you look for if there is a mass on lesion on the lung
look at old XR to see if anything has changed
what are hamartomas composed of
calcified on imaging and has cartilage and lung tissue
small cell lung cancer what does it look like
poor differentiated small cells, central tumor on smokers and increased mitosis
small cell lung cancer: what are the paraneoplastic syndromes
ADH, ACTH, and Lambert Eaton (presynaptic calcium channels)
squamous cell carcinoma histology
keratin pearls and intracellular bridges which are desmosomal connections
where is the squamous cell tumor and what are the paraneoplastic syndromes
PTHrP and increased Ca, and central tumor of male smokers
large cell tumor histology
poor differentiation with poor prognosis
bronchioloalveloar tumor
tumor on small airway and malignant Clara cells and peripheral looks like pneumonia and walls of alveoli are replaced by tall columnar cells
carcinoid tumors
neuroendocrine tumors and polyp mass on the bronchi positive chromogranin
what cancer is involved or moves to the pleura
adenocarcinoma
what are some of the complications of lung cancer
pleural involvement (adenocarcinoma), obstruction of the SVC, phrenic or laryngeal nerve, pan coast tumor (pinpoint pupil, and anhidrosis of the forehead , and ptosis
where does a lung tumor met to
adrenal glands
what are the things associated with potter sequence or syndrome
pulmonary hypoplasai, oligohydramnios, twisted face, twistedd skin, extremity defects, renal failures in utero
what are the causes of potter sequence
ARPKD (small cysts on kidneys in utero), obstructive uropathy (prosterior urethral valvees), bilateral renal agenesis, chronic placental insufficiency
what poles of the kidneys fuse on horseshoe kidney
it is inferior poles that are fused.
what does the horseshoe kidney get stuck on
IMA
what are horseshoe kidneys associated with
hydronephrosis, renal stones, infection, chromosomal aneuploidy and sometimes cancer
neural crest derivatives
melanocytes, aorticopulmonary septum, ganglia, irirs, chromaffin cells, cranial nerves, odontoblasts, ossibles, parafollicular cells, sclera
what is the male formation like from the internal and external path
SRY end turns on testis determining factor and it hits the testes and increases the serotli cells
- internal - settle cells secrete mullein inhibitory factor and this degenerates the paramesonephric ducts
- external- the leydig cells are stimulates to secrete testosterone and this cause the wolfing duct to develop which is the internal structures like the everything but the prostate. It then converts to DHT and this is what starts the male external genitalkia
what happens if there are no sertoli cells or they lack MIF
develop male and female internal genitalia and male external genitalia
what happens if 5 alpha reductase is deficitnet
inability to convert t to DHT causes male internal genitalia nbut ambigious on the outside- Dominican children that sprout penises at puberty.
Paramesoneprhic development
no SRY gene, so it develops into female internal structures, fallopian tubes, uterus, upper portion of the vagina
what happens for mullein agensis
may present as primary amenorrhea due to lack of uterus with females with full functional ovaries and secondary sexual chaaracterisics
what is the homolog of glans penis
clit
what is the homolog of crops vavernosu man spongiosum
vestibular bulbs
what is the homolog of bulbourethral glands
greater vestibular glands
what is the homolog of prostate gland
urethral and parauterthal glands
what is the homolog of ventral shaft of the penis
labia minora
what is the homolog of scrotum
labia majora
hypospadia
the opening is on the bottom and its the failure of the urethral folds
what other conditions are associated with hypospadias
inguinal hernia, and crytorchidism
epispadias
abnoraml opening of the penile urethra on dorsal surface of the penis due to faulty genital tubercle
what are the other conditions associated with epispadias
extrophy of the bladder
what do the letters of APGAR stand for
A-appearance P- pulse G-grimace A-Activity R-respiration
what is the APGAR score that requires further evalulation
7 or under
testicular atrophy, long extremities, gynecomastia, female hair distribution, and intellectual disabiltiy- what in the condition and what are the hormonal level with it
Klinefelter 47 XXY, it is increased LH and Increased FSH and decreased T and since there is dysgenesis of the seminiferous tubules that is why the FSH is high and the bas normal leydig cells decrease the T and increase the LH and estrogen from the extra androgens hanging around
female with short stature, ovary dysgenesis, shield chest webbed neck, cystic hydra, llynpahedam of hands and feet- what in the condition and what are the hormonal level with it
it is a Turner syndrome 45XO- there is decreased estrogeen which leads to increased LH and FSH. Some are mosaic which is somatic mosaicism. it is the most common form of primary ammenorhea
what are the conditions associated with Turner syndrom
bicuspid aortic valve, horseshoe kidney, and coarction of the aorta
is pregnancy possible with Turner
yes if you give them IVF, exogenous estradiol 17b and progesterone
what are double Y males like
phenotypically normal but very tall may be assocaited wit severe acne, learning disability, autism spectrum
ovotesticular disorder of sexual development
both ovarian and testicualr tissue is present wit ambiguous genitalia- true hermaphroditism
PCOS- hormones and what happesn
hyperinsulinemia and or insulin resistance hypothesized to alter the hypothalamic hormonal feedback response and so this increases LH and FSH and increased androgens like testosterone from the theca cells and this decreases the rate of follicular maturation and leads to unruptured follicles and involution
what is the presentation of PCOS
it is bilateral large cystic ovaries wit amenorrhea, oligomenrrhea, hirsutism, acnes, and decreased fertility associated with obesitiy
