neonatal infections
Thrush
Oral candidiasis; peaks at 14 days of life.
Clinically. White plaques on erythematous base over oral mucosa, tongue.
Treatment. Nystatin suspension 100,000 to 200,000 U PO QID for 7 days.
Mycostatin cream to maternal areola and nipple if breast-fed infant.
Neonatal Bacterial Sepsis
General comments. Neonatal bacterial sepsis is associated with 10% to 40%
mortality and significant morbidity, especially neurologic sequelae of
meningitis. Infants <1 month old are immunologically deficient and are
predisposed to serious infections.
Predisposing factors. Premature rupture of membranes (>24 hours), premature
labor, maternal fever, UTI, foul lochia, chorioamnionitis, IV catheters (in
infant), intrapartum asphyxia, and intrauterine monitoring (pressure catheter
or scalp electrode).
Organisms.
Early infection (0 to 4 days of age). Group B streptococci and Escherichia coli
60% to 70% of infections. Also Listeria (rare in
Late infection (>5 days of age). Staph. aureus, group B streptococci, E.
coli, Klebsiella, Pseudomonas, Serratia, Staph. epidermidis, Haemophilus
influenzae.
Signs and symptoms. Presentation may be subtle; thus any febrile neonate must
have a septic work-up. Fever may be absent; so watch for symptoms below.
The presentation may include irritability, vomiting, poor feeding, poor
temperature control, lethargy, apneic spells.
May progress to respiratory distress, poor perfusion, abdominal distension,
jaundice, bleeding, petechiae, or seizures.
Bulging fontanel is a very late sign of neonatal meningitis, and Brudzinski's
sign or Kernig's sign is rarely found.
Work-up.
Include LP for cell count, protein, glucose, and culture.
UA, CBC (remember neutropenia or thrombocytopenia are also suggestive of
infection) and repeat in 5 hours, CXR and C-reactive protein.
Cultures of blood, urine, and any other site as indicated. Latex agglutination
test for pneumococcus, E. coli, H. influenzae, group B streptococci, and
meningococcus in blood, urine, and CSF is done even though the usefulness is
questionable. Negative latex agglutination tests do not rule out infection, but
positive results may help guide therapy.
Associated lab findings. Hypocalcemia, hypoglycemia, hyponatremia, and DIC.
Treatment.
Should be tailored to age of onset, clinical setting, and initial findings.
There should be NO DELAY in antibiotic therapy. Begin empiric therapy after
cultures are obtained or before cultures if any delay is anticipated.
Empiric early (0 to 4 days old). Ampicillin 50 mg/kg/day (100 mg/kg/day in
meningitis) divided 12 hours IV and gentamicin 5 mg/kg/day divided 12 hours IV.
Empiric late (>5 days old). Depends on cause (for example,
methicillin-resistant Staph. aureus outbreak requires vancomycin) ampicillin
100 to 200 mg/kg/day divided Q8h plus (ceftriaxone 100 mg/kg/day IV Q12h or
cefotaxime 150 mg/kg/day IV Q8h), or ampicillin-gentamicin as above usually
adequate.
Repeat cultures in 24 to 48 hours. In meningitis, repeat LP every day until
clear.
There are isolates of Streptococcus pneumoniae that are resistant to penicillin
and cephalosporins. Depending on your institution, vancomycin plus rifampin
should be added to the above regimens until sensitivities are known.
Other. Hemodynamic, respiratory, hematologic, metabolic, and nutritional
support and surveillance are critical. Shock may require volume expansion (FFP
preferred) or respiratory depression may require supplemental oxygen or
artificial ventilation
**In a pregnant patient with chronic
hypertension and no underlying renal disease, the best indicator of
superimposed preeclampsia is
a. proteinuria (300 mg/24 hr)
b. hyperuricemia
c. exacerbation of hypertension, as evidenced by a 10-mm Hg increase in
diastolic blood pressure
d. edema
A
In the absence of renal disease, the onset of proteinuria (at least 300 mg/24 hr) is the best indicator of superimposed preeclampsia in a patient with chronic hypertension.
**Which one of the following is true of a
pregnant patient who has diabetes mellitus?
a. Adjustments in hypoglycemic medications are best made by following urine
glucose readings
b. Oral hypoglycemic agents are useful during pregnancy in patients with mild
diabetes mellitus
c. A precise knowledge of fetal age is important to a successful outcome for
the fetus
d. Because the fetal pancreas helps control the diabetes, ketoacidosis is less
likely during pregnancy
C
Ideally, the child of an overtly diabetic woman should be delivered close to term. Precise knowledge of fetal age (by menstrual history, accurate measurements of uterine height during the second trimester, and confirmation by sonography) is very important to a successful outcome for the fetus. In diabetic women the likelihood of severe metabolic acidosis is increased appreciably. Oral hypoglycemics should not be used during pregnancy. Pregnant diabetic women should be maintained in glucose homeostasis as close as possible to that of nondiabetic pregnant females. Home serum glucose monitoring has become the standard practice and is replacing urine glucose monitoring.
**Severe growth retardation is diagnosed in the fetus of a 19-year-old unmarried white female at 36 weeks gestation. The diagnosis is based on biparietal diameter and there is scant amniotic fluid.
Which one of the following is the most appropriate
management?
a. Perform serial L/S ratios until greater than 3.0, followed by prompt
delivery
b. Induce labor, with careful fetal monitoring
c. Perform an immediate cesarean section
d. Follow the mother weekly with serial ultrasounds
e. Follow the mother weekly with nonstress tests
B
Appropriate management of the preterm infant who is severely growth retarded depends on several factors. Generally those near term should be delivered promptly. By the time that growth retardation has become severe, the fetus is usually mature enough to survive if delivered promptly. However, the fetus must be monitored carefully during labor, with facilities for immediate cesarean section if there is deterioration, and the neonate must receive excellent neonatal care beginning immediately after delivery.
**Ultrasonography reveals placenta previa in a
41-year-old asymptomatic gravida 4 para 3 at 21 weeks gestation. Appropriate
management would be
a. weekly speculum examinations under aseptic conditions beginning in her third
trimester to assess the risk of bleeding
b. an MRI scan, with a repeat scan later in the pregnancy if indicated
c. repeat ultrasonography in her third trimester
d. cesarean delivery at 28 weeks gestation if her L/S ratio is favorable
e. reassurance that ultrasound diagnosis of placenta previa without evidence of
bleeding is no cause for concern and can be disregarded
C
The incidence of placenta previa ranges from 6% to 45% in the second trimester, but more than 95% of these resolve by the third trimester. However, it remains a cause for concern and should be watched, not ignored, even if there is no bleeding. This patient should have repeat ultrasonography in her third trimester. An MRI is very helpful but need not be used except in a difficult diagnostic situation. Weekly speculum examinations would create a risk of hemorrhage. Delivery at 28 weeks would not be appropriate in a patient with no symptoms and without confirmation of the persistence of placenta previa.
**A 27-year-old nondiabetic multiparous woman at
39 weeks gestation has had a previously uncomplicated pregnancy. Fundal height
and estimates of fetal size have been at the upper limits of normal for several
weeks. Today the fundus measures 44 cm from the pubis and you estimate on
palpation that the fetus is large. Clinical pelvimetry is normal.
Which one of the following treatment plans is supported by objective clinical
evidence?
a. Perform external podalic version to breech position and deliver vaginally,
in order to decrease the likelihood of shoulder dystocia
b. Place the mother on a 500-calorie/day diet in order to slow fetal weight
gain
c. Perform a cesarean section based on the clinical estimate of above-normal
fetal size
d. Order ultrasonography and perform a cesarean section if estimated fetal
weight is 4000 g
e. Plan vaginal delivery, with personnel in the delivery room who are trained
to assist with a difficult shoulder delivery should it occur
E
No study has demonstrated improvement in fetal outcome with cesarean delivery for estimated fetal weight above 4800 g, either estimated by fundal measurement and palpation or by ultrasonography, except in the case of diabetic women. Statistical estimates show greater increased morbidity and mortality for the mother than any achievable decrease in fetal morbidity and mortality. Therefore, vaginal delivery should generally be planned with delivery room personnel present to assist, should shoulder dystocia occur. An extremely low-calorie diet would be contraindicated and dangerous to both mother and fetus. External podalic version would be contraindicated and place the fetus at risk of a dangerous breech delivery.
**Following a prolonged labor and traumatic
delivery, a 5015 gram (11 lb 1 oz) white male infant holds his right arm in an
abducted and internally rotated position with extension at the elbow, pronation
of the forearm, and flexion of the wrist. Although the grasp reflex is intact,
the biceps and brachioradialis reflexes are absent.
The most likely diagnosis is a
a. rotator cuff tear
b. clavicle fracture
c. brachial plexus injury
d. cerebral injury
e. fractured humerus
C
The clinical picture in this infant is typical of brachial plexus injury. Most cases of brachial plexus injury follow a prolonged and difficult labor culminating in a traumatic delivery. Duchenne-Erb (upper arm) paralysis, resulting from injury of the fifth and sixth cervical roots, is by far the most common manifestation of this disorder. The infant with upper arm paralysis holds the affected arm in a characteristic position, reflecting involvement of the shoulder abductors and external rotators, forearm flexors and supinators, and wrist extensors. In addition, the Moro, biceps, and brachioradialis reflexes are absent. Roentgenographic studies of the shoulder should be made to exclude tearing of the joint capsule, fracture of the clavicle, and fracture, dislocation, or upper epiphyseal detachment of the humerus. Cerebral injury is usually evidenced by other signs of central nervous system damage. Typically, rotator cuff tears are not associated with neurologic findings.
**Which one of the following is an absolute
contraindication to tocolytic treatment for preterm labor?
a. Urinary tract infection
b. Documented gestation less than 28 weeks
c. Chorioamnionitis
d. Uncontrolled diabetes mellitus
e. Any vaginal bleeding due to mild abruptio placentae
C
Before tocolytic treatment is instituted,
absolute contraindications to tocolysis must be ruled out. These include
chorioamnionitis, severe abruptio placentae, severe bleeding from any cause,
severe pregnancy-induced hypertension, fetal death, fetal anomaly incompatible
with life, and severe fetal growth retardation. Chorioamnionitis may
precipitate preterm labor and is an absolute contraindication to tocolysis. It
may be present in a febrile pregnant patient even with intact membranes. In
this case amniocentesis may be required to rule out infection. There are also a
number of relative contraindications. These include uncontrolled diabetes,
hyperthyroidism, maternal cardiac disease, mild chronic hypertension, mild
abruptio placentae, stable placenta previa, fetal distress, fetal anomaly, mild
fetal growth retardation, and cervical dilatation greater than 5 cm. In patients
with relative contraindications to tocolysis the risk of complications from
prematurity must be weighed against the risk of tocolysis. Not all vaginal
bleeding is due to a serious obstetric condition. Cervical effacement or
dilatation may be the cause. Even if the source of bleeding is determined to be
a placental abruption, if the bleeding is minor, the abruption is mild, and the
fetus is not in distress, tocolysis is not absolutely contraindicated.
While diabetes mellitus may be adversely affected by beta-adrenergic tocolytic
agents, it is not an absolute contraindication to tocolysis. Close glycemic
monitoring is, of course, mandatory. Even a few weeks of effective tocolysis
may significantly alter the perinatal outcome of gestations between 25 and 27
weeks. Gestational age less than 28 weeks is therefore not a contraindication
to tocolysis. While a urinary tract infection may precipitate preterm labor,
tocolysis is not contraindicated. The infection, of course, should be treated.
A middlaged man with chest discomfort on
exercise.
Diagnosis: stable angina.
How would you manage this patient.
Please add your input to the following list:
ECG
stress test
nitrates
aspirin
calcium-channel blockers.
1st line lab- CBC, Chem7, Lipid profile, UA,FOBT
Counsell- smoking cessation(if any), reduce alcohol intake, exercise, refer to
dietecian for formulation of diet etc.
Aspirin PO
Metoprolol PO
Nitroglycerin SL prn(prn choice not available)
Take 1 tab SL q5min- if pain not relieved, immediately attend ER
F/U after 7 days.
Evaluation of patients with angina.
ECG. During an episode of pain, the ECG may show ST-segment depression, T-wave
inversions, or it may be normal. The absence of ECG changes during an episode
of angina does not rule out cardiac ischemia because the circumflex and
posterolateral distributions can be electrically silent. Increasing use is
being made of echocardiography and thallium studies (see below) to evaluate
patients with continuing symptoms in the absence of ECG changes. Coronary artery
disease is suggested if there is evidence of an old MI.
Graded exercise stress test or treadmill (GXT). The predictive value of a
positive test depends on the prevalence of disease in the population being
tested. Specificity is high in particular groups of symptomatic individuals but
is generally <50% in asymptomatic individuals. Compared with men, women
(especially young women) have higher rates of false-positive GXT. An early
positive GXT may be indicative of left main disease or three-vessel disease.
Absolute contraindications to GXT include CHF, acute MI, active myocarditis,
unstable angina, recent embolism, dissecting aneurysm, acute illness,
thrombophlebitis, and moderate to severe aortic stenosis. Relative
contraindications include severe hypertension, mild to moderate aortic
stenosis, hypertrophic obstructive cardiomyopathy, frequent ectopy, and many
other conditions that may increase the risk of a GXT.
Thallium dipyridamole scan, or thallium GXT. Thallium dipyridamole scans can be
useful for patients who cannot tolerate the physical demands of the GXT
(because of arthritis, COPD). During the test, thallium is taken up by viable,
well-perfused myocardium. Areas of myocardial infarction are indicated by fixed
perfusion defects with no uptake during rest or exercise. During the
thallium-GXT, areas that are hypoperfused (that is, ischemic) demonstrate
thallium uptake only during the postexercise 'resting' images.
Adenosine, dipyridamole, and dobutamine may be used to augment the perfusion of
normal myocardium and shunt blood flow away from areas of relative ischemia.
These agents are used in patients who have a contraindication to exercise or
are unlikely to attain target heart rates.
Echocardiography. The stress echocardiogram is a widely performed test used to
assess patients for coronary disease. Baseline echocardiographic images are
obtained at rest. These are used to evaluate left ventricular function, wall
motion, and valve function. Images are then acquired during peak stress (that
is, during a GXT or with dobutamine) and compared with those at rest. Regional
wall-motion abnormalities with stress indicate areas of hypoperfusion or
ischemia. Echocardiography is now used routinely to assess CAD in women because
of their high false-positive rate on GXT. It is also gaining increased usage
among patients with an abnormal baseline ECG (that is, LBBB), those receiving
digoxin, and after CABG or PTCA. Transesophageal echocardiography is more
sensitive at identifying abnormalities such as valvular vegetations or atrial
and ventricular thrombi.
Coronary angiography. Used to identify foci of coronary disease. It is the
evaluation of choice in patients with angina that is (1) poorly responsive to
medication, or (2) unstable. It is also indicated in patients with test results
consistent with a high risk for CAD.
Treatment of Angina
Medical. May use two- or three-drug combination to maximize benefit while
minimizing side effects.
Aspirin. Daily aspirin (325 mg) unless contraindicated to inhibit platelet
aggregation.
Beta-blockers (metoprolol, atenolol, nadolol, propranolol, and others).
Decrease myocardial oxygen demand by decreasing heart rate, systolic blood
pressure, and contractility. Because they prolong diastole, beta-blockers also
increase O2 supply by increasing myocardial perfusion time. Some beta-blockers
(those without intrinsic sympathomimetic activity [ISA] activity, especially
lipophilic ones [see below]) prolong life when given for the first year after
an MI. This benefit extends into subsequent years in those with a complicated
course. Lipophilic beta-blockers (timolol, metoprolol, and propranolol)
decrease the incidence of postinfarction ventricular fibrillation and sudden
death in both men and women by increasing the electrical stability of
myocardium. They are also useful in patients whose angina is regularly provoked
by exercise though they may limit exercise tolerance. Start with a low dose and
increase until symptoms are controlled or the resting heart rate is 50 to 60
beats/min. Side effects can include bradycardia, bronchospasm, fatigue, GI
upset, symptoms of
Calcium-channel blockers (verapamil, diltiazem, nifedipine, and others). These
drugs act by blocking the influx of calcium through slow channels into vascular
smooth muscle and myocardial cells. They promote peripheral arterial
vasodilatation, which decreases oxygen demand by decreasing afterload.
Calcium-channel blockers also decrease coronary vasospasm and improve
collateral flow. Diastolic relaxation of the
Nitrates (nitropaste, nitropatches, isosorbide dinitrate, others). Effects
include venous and arteriolar vasodilatation, which decreases oxygen demand.
The resulting coronary artery vasodilatation increases coronary oxygen supply.
Tolerance can develop but can be overcome by providing an 8-hour nitrate-free
interval each day. Preparations include oral, transdermal patches, ointment,
sublingual tablets, or spray. A common side effect is headache, which usually
responds to aspirin or acetaminophen and tends to improve with continued use.
Sublingual nitroglycerin tablets (0.4 mg PRN) or spray are used for acute
episodes of angina and may be repeated at 5-minute intervals for up to 3 doses.
Patients should be instructed to go to the emergency department if angina is
not relieved after 3 doses of nitroglycerin.
ACE inhibitors, though not traditionally indicated for angina, may be useful in
the patient whose symptoms are difficult to control. ACE inhibitors reduce
afterload and directly dilate coronary arteries.
Revascularization.
Coronary artery bypass grafting (CABG). Primary indication is angina refractory
to medical therapy or lesions that are more amenable to surgery than to
angioplasty. CABG has been shown to prolong survival in patients with left main
disease (>50% luminal narrowing) and in three-vessel CAD with
Contraindications. Advanced age with pronounced debility, absence of ischemia,
or ungraftable coronary arteries. Advanced age in and of itself is not a
contraindication. In one sample of patients 80 years and older, coronary
revascularization by either CABG or PTCA (see below) was associated with a high
likelihood of attaining a good or excellent quality of life and of a patient
being able to care for himself or herself subsequent to an MI.
PTCA (percutaneous transluminal coronary angioplasty). Can be useful for
significant (<50% luminal narrowing) single-vessel CAD when lesions are
amenable to the procedure. PTCA does not prevent MI or prolong life. Randomized
clinical trails comparing medical therapy with PTCA in single-vessel disease
have not shown any significant advantage to using PTCA. Several controlled
clinical trials have shown that PTCA can be used as an alternative to CABG in
two- and three-vessel CAD when lesions are amenable to PTCA. There was general
agreement among these trials that the procedures provide equal improvement in
angina. The PTCA groups generally have a higher frequency of antianginal use
after 1 year and are more likely to require additional intervention (CABG or
repeat PTCA) compared to patients who undergo CABG. PTCA is an acceptable
alternative to repeat CABG if lesions are amenable to dilatation (single-vessel
stenosis, or easily accessible two-vessel stenoses). Diabetics have a
particularly poor long-term result with PTCA. Intracoronary stenting may be
preferred in these patients.
Intracoronary stenting. Controlled clinical trials have demonstrated that
intracoronary stenting reduces restenosis rates after PTCA from a range of 40%
to 50% to a range of 15% to 25%. Recently developed stent deployment techniques
using high-pressure balloon inflation and combinations of aspirin and
ticlodipine have reduced the abrupt closure rate for stents to <1% and
reduced hospital stays to 1 or 2 days.

Acute hyponatremia is less common than chronic
hyponatremia and typically is seen in patients with a history of sudden free
water loading (eg, patients with psychogenic polydipsia, infants fed tap water
for 1-2 days, patients given hypotonic fluids in the postoperative period).
Acute evolution of hyponatremia leaves little opportunity for compensatory
extrusion of CNS intracellular solutes.
The ultimate danger for these patients is brainstem herniation when Na levels
fall below 120 mEq/L.
The therapeutic goal is to increase serum sodium rapidly by 4-6 mEq/L over the
first 1-2 hours.
First, the source of free water must be identified and eliminated.
In patients with healthy renal function and mild to moderately severe symptoms,
serum sodium may correct spontaneously without further intervention.
Patients with seizures, severe confusion, coma, or signs of brainstem
herniation should receive hypertonic (3%) saline to rapidly correct serum
sodium toward normal, but only enough to arrest the progression of symptoms.
An increase in serum sodium of 4-6 mEq/L is generally sufficient.
**A 28-year-old gravida 2 para 1 presents to the
emergency department at 16 weeks gestation. She has noted the sudden onset of
dyspnea, pleuritic chest pain, and mild hemoptysis. Both calves are mildly edematous
and somewhat tender. A lung scan shows a high probability of pulmonary emboli.
Which one of the following would be appropriate management at this time?
a. Warfarin therapy only, with the prothrombin time maintained at 18 to 20
seconds (INR 2.0 to 3.0)
b. Aspirin, 81 mg/day throughout the pregnancy
c. Intravenous heparin for 5 to 10 days followed by warfarin anticoagulation
d. Intravenous heparin for 5 to 10 days followed by subcutaneous heparin for
the duration of the pregnancy
e. Placement of an inferior venous umbrella filter
D
The risk of pulmonary embolism is five times
higher in a pregnant woman than in a nonpregnant woman of similar age, and
venous thromboembolism is a leading cause of illness and death during
pregnancy. There has been a considerable change in management over the past two
decades.
Because heparin does not cross the placenta, it is considered the safest
anticoagulant to use during pregnancy. Initially, patients with venous
thromboembolism during pregnancy should be managed with heparin given according
to the recommendations for nonpregnant patients.
Warfarin should not be used throughout pregnancy. It is definitely teratogenic
during the first trimester and extensive fetal abnormalities have been
associated with exposure to warfarin in any trimester. Warfarin readily crosses
the placenta and can result in a host of problems.
Women with venous thromboembolism during pregnancy should receive intravenous
heparin for 5 to 10 days followed by subcutaneous heparin for the duration of
the pregnancy. Warfarin therapy can be given after pregnancy, since it is not
present in breast milk.
The indications for placement of inferior vena cava filters in pregnant
patients are the same as in nonpregnant patients-any contraindication to
anticoagulant therapy, heparin-induced thrombocytopenia, and recurrence of
pulmonary embolism in patients receiving adequate anticoagulant therapy.
There are no data to support the use of treatment or prophylaxis of pulmonary
embolism either during or after pregnancy.
**A 24-year-old white primigravida has developed
several 1- to 2-mm erythematous papules on her abdomen in the third trimester.
They are pruritic and tend to appear in her striae. Liver function tests and a
CBC are normal.
Which one of the following is the most likely diagnosis?
a. Pruritus gravidarum
b. Spangler's papular dermatitis
c. Impetigo herpetiformis
d. Herpes gestationis
e. Pruritic urticarial papules and plaques (PUPP)
E
The findings in this patient are most consistent with PUPP. This condition is usually benign, is not associated with increased fetal morbidity, and resolves after delivery, and there is usually no recurrence in subsequent pregnancies. Herpes gestationis, impetigo herpetiformis, and Spangler's papular dermatitis have different presentations and may be associated with increased fetal morbidity. Pruritus gravidarum is characterized by pruritus without skin lesions.
My approach:
Intravenous access, Oxygen, morphine, nitroglycerin SL, if pain persists after
3 SL, assume MI and start IV nitroglycerin, and titrate dose upwards until pain
relieved). Monitor vital signs (how often, not sure).
ECG (how often), chem7, CBC, UA, Chest X ray, lipid profile
Troponin T, I, CK-MB
Stress test to risk stratify
If stable, follow earlier discussion on stable angina
If unstable, then admit the patient, prepare for coronary angiography, and
consider ballon angiography with or w/o a stent in the same session.
tPA
metoprolol, IV (if no contraindications)
aspirin
low molecular heparin, IV
IIb/IIIa blockers: abciximab or tirofoban, or eptifibatide
treat any arrythmias and other complications
Admit if: new angina
accelerating angina
admit to a monitored bed.
If angiography single vessel: PTCA, triple or left main (esp. w/ LV dysfunction):
CABG, double and some triple, either PTCA or CABG, if no major stenosis,
medical therapy, but be wary of acute coronary syndrome still, consider stress
test, if inconclusive still, consider additional stress echocardiogram, or
stress myocardial perfusion scintigram. If none of these positive (inclucding
ECG), investigate other organ systems.
Long term management:
Aggressive and extensive risk factor modification
Continue LMW heparin if recurrent and high risk for MI in whom
revascularization not possible.
Beta-blockers: metaprolol
quit smoking,
lipid lowering therapy
ACE inhibitors
Please try to develop a better algorithm and change any sequence if you think
anything I did was not in the right order.
