The Trendelenburg Test or
Brodie-Trendelenburg test is a test which can be carried out as part of a
physical examination to determine the competency of the valves in the
superficial and deep veins of the legs in patients with varicose veins.[1]
Procedure
With the patient in the supine position,
the leg is flexed at the hip and raised above heart level. The veins will empty
due to gravity or with the assistance of the examiner's hand squeezing blood
towards the heart.
A tourniquet is then applied around the
upper thigh to compress the superficial veins but not too tight as to occlude
the deeper veins. The leg is then lowered by asking the patient to stand.
Normally the superficial saphenous vein
will fill from below within 30-35 seconds as blood from the capillary beds
reaches the veins; if the superficial veins fill more rapidly with the
tourniquet in place there is valvular incompetence below the level of the
tourniquet in the "deep" or "communicating" veins. After 20
seconds, if there has been no rapid filling, the tourniquet is released. If
there is sudden filling at this point, it indicates that the deep and
communicating veins are competent but the superficial veins are incompetent.[2]
The test is reported in two parts, the
initial standing up of the patient (positive or negative based on rapid
filling) and the second phase once the tourniquet is removed (positive or
negative based upon rapid filling).
For example, a possible outcome of the test
would be negative-positive meaning that the initial phase of the test was
negative indicating competence in the deep and communicating veins and the
second phase of the test was positive meaning that there is superficial vein
incompetence.
The test can be repeated with the
tourniquet at different levels to further pinpoint the level of valvular
incompetence:
above the knee - to assess the mid-thigh
perforators
below the knee - to assess incompetence
between the short saphenous vein and the popliteal vein.[3]
Superficial veins of the leg normally empty
into deep veins, however retrograde filling occurs when valves are incompetent,
leading to varicose veins.

Hereditary nonpolyposis colon cancer
syndrome (HNPCC, Lynch syndrome) poses about a 40% lifetime risk for developing
colorectal cancer; individuals with this syndrome are also at increased risk
for urothelial cancer, endometrial cancer,
The approximate 5-year survival rate for
colorectal cancer patients in the United States (all stages included) is
65%.[19] Survival is inversely related to stage: approximate 5-year survival
rates are 95% for patients with stage I disease, 60% for those with stage III
disease, and 10% for those with stage IV (metastatic) disease (see Staging).
The Dukes staging system is a
classification system for colorectal cancer. This system is now mainly of
historical interest as it has largely been replaced by the TNM staging system.
It is not recommended for clinical practice.

Oral cholecystography is a procedure used
to visualize the gallbladder by administering, by mouth, a radiopaque contrast
agent that is excreted by the liver. This excreted material will collect in the
gallbladder, where reabsorption of water concentrates the excreted contrast.
Since only 10% of gallstones are radiopaque, the remaining 90% will appear as
translucent on an opaque background in an abdominal X-ray. Current medical
practice prefers ultrasound and CT over oral cholecystography. If needed, IV
cholecystography and cholangiography may be done.

Celiac disease, also known as celiac sprue
or gluten-sensitive enteropathy, is a chronic disorder of the digestive tract
that results in an inability to tolerate gliadin, the alcohol-soluble fraction
of gluten. Gluten is a protein commonly found in wheat, rye, and barley.
When patients with celiac disease ingest
gliadin, an immunologically mediated inflammatory response occurs that damages
the mucosa of their intestines, resulting in maldigestion and malabsorption of
food nutrients.(some web site say auto immune)

common bile duct diameter
A new sonographic technique for
demonstration of the common bile duct is described in a prospective study of
200 patients. The mean diameter of the normal common duct was 4.1 mm. A common
duct greater than 7 mm in diameter can be seen in (a) nonjaundiced patients
with gallstones and/or pancreatitis, or (b) jaundiced patients with common duct
obstruction by stone or tumor. A common duct greater than 11 mm in diameter is
strongly suggestive of obstruction by stone or tumor.

The hallmark physical findings in intussusception
are a right hypochondrium sausage-shaped mass and emptiness in the right lower
quadrant (Dance sign).
See Clinical Presentation for more detail.
Diagnosis
Imaging studies used in the diagnosis of
intussusception include the following:
Radiography: Plain abdominal radiography
reveals signs that suggest intussusception in only 60% of cases
Ultrasonography: Hallmarks of
ultrasonography include the target and pseudokidney signs
Contrast enema: This is the traditional and
most reliable way to make the diagnosis of intussusception in children
See Workup for more detail.
Management
Nonoperative reduction
Therapeutic enemas include the following:
Hydrostatic: With barium or water-soluble
contrast
Pneumatic: With air insufflation; this is
the treatment of choice in many institutions, and the risk of major
complications with this technique is small
Surgical reduction
Hepatic encephalopathy is also described in
patients without cirrhosis with either spontaneous or surgically created portosystemic
shunts
It is theorized that neurotoxic substances,
including ammonia and manganese, may gain entry into the brain in the setting
of liver failure.
ammonia is detoxified in the liver by
conversion to urea by the Krebs-Henseleit cycle.
Grading of the symptoms of hepatic
encephalopathy is performed according to the so-called West Haven
classification system, as follows[26] :
Grade 0 - Minimal hepatic encephalopathy
(also known as CHE [27] and previously known subclinical hepatic
encephalopathy); lack of detectable changes in personality or behavior; minimal
changes in memory, concentration, intellectual function, and coordination;
asterixis is absent.
Grade 1 - Trivial lack of awareness;
shortened attention span; impaired addition or subtraction; hypersomnia,
insomnia, or inversion of sleep pattern; euphoria, depression, or irritability;
mild confusion; slowing of ability to perform mental tasks
Grade 2 - Lethargy or apathy;
disorientation; inappropriate behavior; slurred speech; obvious asterixis;
drowsiness, lethargy, gross deficits in ability to perform mental tasks,
obvious personality changes, inappropriate behavior, and intermittent
disorientation, usually regarding time
Grade 3 - Somnolent but can be aroused;
unable to perform mental tasks; disorientation about time and place; marked
confusion; amnesia; occasional fits of rage; present but incomprehensible
speech
Grade 4 - Coma with or without response to
painful stimuli
Classic EEG changes associated with hepatic
encephalopathy are high-amplitude low-frequency waves and triphasic waves.
Medications: Drugs that act upon the
central nervous system, such as opiates, benzodiazepines, antidepressants, and
antipsychotic agents, may worsen hepatic encephalopathy.
Diuretic therapy: Decreased serum potassium
levels and alkalosis may facilitate the conversion of NH4+ to NH3. At the
author’s institution, diuretic-induced hypovolemia is the most common reason
for patients with previously well-controlled hepatic encephalopathy to present
to the emergency room with worsening mental function.
Avoid medications that depress central
nervous system function, especially benzodiazepines. Patients with severe
agitation and hepatic encephalopathy may receive haloperidol as a sedative.
Treating patients who present with coexisting alcohol withdrawal and hepatic
encephalopathy is particularly challenging. These patients may require therapy
with benzodiazepines in conjunction with lactulose and other medical therapies
for hepatic encephalopathy.
Lactulose appears to inhibit intestinal
ammonia production by a number of mechanisms. The conversion of lactulose to
lactic acid results in acidification of the gut lumen. This favors conversion
of NH4+ to NH3 and the passage of NH3 from tissues into the lumen. Gut acidification
inhibits ammoniagenic coliform bacteria, leading to increased levels of
nonammoniagenic lactobacilli. Lactulose also works as a cathartic, reducing
colonic bacterial load.
Initial lactulose dosing is 30 mL orally,
daily or twice daily
tx for hepatic encephalopathi
Neomycin and other antibiotics, such as
metronidazole, oral vancomycin, paromomycin, and oral quinolones, are
administered in an effort to decrease the colonic concentration of ammoniagenic
bacteria. Initial neomycin dosing is 250 mg orally 2-4 times a day. Doses as
high as 4000 mg/d may be administered. Neomycin is usually reserved as a
second-line agent, after initiation of treatment with lactulose. Long-term
treatment with this oral aminoglycoside runs the risks of inducing ototoxicity
and nephrotoxicity because of some systemic absorption.
Rifaximin (Xifaxan), a nonabsorbable
derivative of rifampin, has been used in Europe
LOLA (Hepa-Merz) is available in Europe in
both intravenous formulations and oral formulations. It is not available in the
United States. LOLA is a stable salt of the 2 constituent amino acids.
L-ornithine stimulates the urea cycle, with resulting loss of ammonia.
pernicious anaemia
noun
a deficiency in the production of red blood
cells through a lack of vitamin B12.
The etiology of vitamin B12 deficiency is
diverse and includes lack of intrinsic factor (IF), altered pH in the small
intestine, and lack of absorption of B12 complexes in the terminal ileum.
Vitamin B12 deficiency from any cause, as well as folic acid deficiency, can
result in megaloblastic anemia.
Impaired IF production can occur in adults
due to autoimmune destruction of parietal cells, which secrete IF. Gastrectomy
can significantly reduce the production of IF.
The genetic defect in FAP is a germline
mutation in the adenomatous polyposis coli (APC) gene.

Endoscopic surveillance for FPC
Note the following:
Flexible sigmoidoscopy should be performed every
1-2 years starting at age 10-12 years in patients with FAP to document the
onset of polyposis.
Sigmoidoscopic surveillance and ablation of
any polyps in the retained rectum or ileal pouch should be performed every 3-6
months in patients with FAP who have undergone colonic (total or subtotal)
resection. There is an increased risk for adenomas and carcinomas in the ileal
pouch, as there is increased epithelial cell proliferation at this site as
compared to the afferent ileal loop. [21, 22]
Once polyps are detected, colonoscopic
surveillance is recommended to remove large polyps in patients who have not had
an operation. This is important because surgery (colectomy) is usually deferred
until an appropriate psychological age is reached (usually late teenaged years
to early twenties). However, if the polyps have advanced histologic features,
then early surgery is recommended.
Front- and side-view
esophagogastroduodenoscopy should be performed every 1-3 years once the
diagnosis is made and after surgical therapy. The front-view
esophagogastroduodenoscopy allows for the detection of gastric and duodenal
polyps. The side-view duodenoscope allows for the examination of the ampulla of
Vater.
Capsule endoscopy is useful for the
surveillance of jejunal-ileal polyps in selected patients but is not
recommended for duodenal or ampullary surveillance. Some patients who are at
high risk may benefit from screening with endoscopic ultrasound for
periampullary and ampullary tumors. [

Gastrin is a peptide hormone that
stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach
and aids in gastric motility. It is released by G cells in the pyloric antrum
of the stomach, duodenum, and the pancreas.
Zollinger-Ellison syndrome (ZES) is caused
by a non–beta islet cell, gastrin-secreting tumor of the pancreas that
stimulates the acid-secreting cells of the stomach to maximal activity, with
consequent gastrointestinal mucosal ulceration. ZES may occur sporadically or
as part of an autosomal dominant familial syndrome, multiple endocrine
neoplasia type 1 (MEN 1). The primary tumor is usually located in the duodenum,
the pancreas, and abdominal lymph nodes, but ectopic locations have also been
described (eg, heart, ovary, gall bladder, liver, kidney).

1.First, breast symmetry, size, general
density, and glandular distribution are observed.
2.Next, a search for masses, densities,
calcifications, architectural distortions, and associated findings is performed.
3. For masses, the shape, margins, and
density are analyzed. The features of benign and malignant masses can be
similar. Benign masses are often round or oval with circumscribed margins.
Malignant lesions tend to have irregular, indistinct, or spiculated margins.
Malignancies tend to have density greater than that of the normal breast
tissue. The presence of very low density fat in a lesion often indicates benign
findings such as oil cysts, lipomas, galactoceles, and hamartomas.
Calcifications can also be the first sign
of cancer or a harmless process in the breast. Benign calcifications are
usually larger than calcifications associated with malignancy. They are usually
coarser, often round with smooth margins, and more easily seen. Benign
calcifications tend to have specific shapes
Calcifications associated with malignancy
are usually small (< 0.5 mm) and often require high-resolution magnification
imaging with digital zooming for accurate assessment. They tend to have a
pleomorphic or heterogeneous shape or a fine granular, fine linear, or
branching (casting) shape.
The distribution of the calcification can
provide clues to the underlying process and should be specified as grouped,
clustered, linear, segmental, regional, or diffuse.
Special findings may be encountered, such
as a linear density that might represent a duct filled with secretions or a
reniform-shaped mass with a radiolucent center that is typical of an
intramammary lymph node.
Associated findings are then taken into
account. These include skin or nipple retraction, skin thickening (which may be
focal or diffuse), trabecular thickening, skin lesions, axillary adenopathy,
and architectural distortion.
screening of prostate cancer
The recommended age for starting screening
is as follows:
50 years of age for men at average risk who
have at least a 10-year life expectancy
40 or 45 years of age for African Americans
and men who have had a first-degree relative diagnosed with prostate cancer
before age 65 years
40 years of age for men with several
first-degree relatives who had prostate cancer at an early age
No PSA level guarantees the absence of
prostate cancer.
The risk of disease increases as the PSA
level increases, from about 8% with a PSA level of 1 ng/mL to about 25% with a
PSA level of 4-10 ng/mL
No PSA=100% no prostate cancer
Metastatic prostate cancer
Metastatic prostate cancer is rarely
curable,
Paget's disease of bone is a chronic
disorder that can result in enlarged and misshapen bones. Paget's is caused by
the excessive breakdown and formation of bone, followed by disorganized bone
remodeling. This causes affected bone to weaken, resulting in pain, misshapen
bones, fractures and arthritis in the joints near the affected bones. Rarely,
it can develop into a primary bone cancer known as Paget's sarcoma. Often
Paget's disease is localized to only a few bones in the body. The pelvis,
femur, and lower lumbar vertebrae are the most commonly affected bones.

Hemophilia A is an X-linked, recessive
disorder caused by deficiency of functional plasma clotting factor VIII
(FVIII), which may be inherited or arise from spontaneous mutation. The
development of inhibitory antibodies to FVIII can result in acquired hemophilia
A or can complicate the treatment of genetic cases.
Hemophilia B, or Christmas disease, is an
inherited, X-linked, recessive disorder that results in deficiency of
functional plasma coagulation factor IX. Spontaneous mutation and acquired
immunologic processes can result in this disorder as well. Hemophilia B
constitutes about 20% of hemophilia cases, and about 50% of these cases have
factor IX levels greater than 1%.
Normal values for FVIII assays are 50-150%.
Values in hemophilia are as follows:
Mild: >5%
Moderate: 1-5%
Severe: < 1%
been based on either clinical bleeding
symptoms or on plasma procoagulant levels; the latter are the most widely used
criteria. Classification according to plasma procoagulant levels is as follows:
Severe hemophilia - FVIII level less than
1% of normal (< 0.01 IU/mL)
Moderate hemophilia - FVIII level 1-5% of
normal (0.01-0.05 IU/mL)
Mild hemophilia - FVIII level more than 5%
but less than 40% of normal (>0.05 to < 0.40 IU/mL)
Hemophilia C (deficiency of factor
XI)
Even in severe deficiency of factor XI, the
bleeding tendency is mild. Unlike the bleeding tendency in hemophilia A or

Juvenile idiopathic arthritis (JIA) is the
most common cause of chronic arthritis in children.
Friedreich's ataxia is an autosomal
recessive inherited disease that causes progressive damage to the nervous
system. It manifests in initial symptoms of poor coordination such as gait
disturbance; it can also lead to scoliosis, heart disease and diabetes, but
does not affect cognitive function. T
The ataxia of Friedreich's ataxia results
from the degeneration of nervous tissue in the spinal cord, in particular
sensory neurons essential (through connections with the cerebellum) for
directing muscle movement of the arms and legs. The spinal cord becomes thinner
and nerve cells lose some of their myelin sheath

Muscle weakness in the arms and legs
Loss of coordination
Vision impairment
Hearing impairment
Slurred speech
Curvature of the spine (scoliosis)

the foot)
Diabetes (about 20% of people with
Friedreich's ataxia develop carbohydrate intolerance and 10% develop diabetes
mellitus)[6]

and resultant tachycardia (fast heart rate) and hypertrophic cardiomyopathy)
Juvenile idiopathic arthritis
(JIA)/juvenile chronic arthritis
commonest chronic inflamatory Dx
It is defined as persistent joint swelling
(of >6 weeks duration) presenting before 16 years of age in the absence of
infection or any other defined cause.
. Its classification is clinical and based
on the number of joints affected in the first 6 months, as polyarthritis (more
than four joints) (Fig. 26.16) and oligoarthritis (up to and including four
joints) or systemic (with fever and rash). Psoriatic arthritis and enthesitis
are further subtypes. Subtyping is further classified according to the presence
of rheumatoid factor and HLA B27 tissue type.
Complications
Chronic anterior uveitis
This is common but asymptomatic and can
lead to severe visual impairment. Regular ophthalmological screening using a
slit lamp is indicated, especially for children with oligoarticular disease.

Henoch–Schönlein purpura
Henoch–Schönlein purpura is the combination
of some of the following features:
Characteristic skin rash
Arthralgia
Periarticular oedema
Abdominal pain
Glomerulonephritis.
It usually occurs between the ages of 3 and
10 years, is twice as common in boys, peaks during the winter months and is
often preceded by an upper respiratory infection
children often have a fever. The rash is
the most obvious feature. It is symmetrically distributed over the buttocks,
the extensor surfaces of the arms and legs, and the ankles. The trunk is spared
unless lesions are induced by trauma. The rash may initially be urticarial,
rapidly becoming maculopapular and purpuric,
Colicky abdominal pain occurs in many
children and, if severe, can be treated with corticosteroids. Gastrointestinal
petechiae can cause haematemesis and melaena. Intussusception can occur and can
be particularly difficult to diagnose under these circumstances
Over 80% have microscopic or macroscopic
haematuria or mild proteinuria
Adult-onset Still's disease (AOSD) is a
rare systemic inflammatory disease characterized by the classic triad of
persistent high spiking fevers, joint pain and a distinctive salmon-colored
bumpy rash.

Whooping cough (pertussis)
This is a highly contagious respiratory
infection caused by Bordetella pertussis. It is endemic, with epidemics every
3–4 years. After a week of coryza (catarrhal phase), the child develops a
characteristic paroxysmal or spasmodic cough followed by a characteristic
inspiratory whoop (paroxysmal phase). The spasms of cough are often worse at
night and may culminate in vomiting. During a paroxysm, the child goes red or
blue in the face, and mucus flows from the nose and mouth. The whoop may be
absent in infants, but apnoea is a feature at this age. Epistaxis and
subconjunctival haemorrhages can occur after vigorous coughing. The paroxysmal
phase lasts 3–6 weeks. The symptoms gradually decrease (convalescent phase) but
may persist for many months. Complications of pertussis, such as pneumonia,
convulsions and bronchiectasis, are uncommon, but there is still a significant
mortality, particularly in infants. Infants who have not yet completed their
primary vaccination at 4 months are particularly susceptible
The organism can be identified early in the
disease from culture of a per-nasal swab, although PCR is more sensitive.
Characteristically, there is a marked lymphocytosis (>15 × 109/L) on a blood
count. Although erythromycin eradicates the organism, it decreases symptoms
only if started during the catarrhal phase. Siblings, parents and school
contacts may develop a similar cough, and close contacts should receive
erythromycin prophylaxis
Bronchiolitis
Bronchiolitis is the commonest serious
respiratory infection of infancy: 2–3% of all infants are admitted to hospital
with the disease each year during annual winter epidemics; 90% are aged 1–9
months (bronchiolitis is rare after 1 year of age). Respiratory syncytial virus
(RSV) is the pathogen in 80% of cases. The remainder are accounted for by human
metapneumovirus, parainfluenza virus, rhinovirus, adenovirus, influenza virus,
and Mycoplasma pneumoniae. Dual infection with RSV and human metapneumovirus is
associated with severe bronchiolitis.

3.convulsant phase
In pyloric stenosis, there is hypertrophy
of the pyloric muscle causing gastric outlet obstruction. It presents at
between 2 and 7 weeks of age, irrespective of gestational age. It is more
common in boys (4 : 1), particularly first-borns, and there may be a family
history, especially on the maternal side.
Clinical features are:
Vomiting, which increases in frequency and
forcefulness over time, ultimately becoming projectile
Hunger after vomiting until dehydration
leads to loss of interest in feeding
Intussusception describes the invagination
of proximal bowel into a distal segment. It most commonly involves ileum
passing into the caecum through the ileocaecal valve (Fig. 13.6a).
Intussusception is the commonest cause of intestinal obstruction in infants
after the neonatal period. Although it may occur at any age, the peak age of
presentation is between 3 months and 2 years.
that viral infection leading to enlargement
of Peyer’s patches may form the lead point of the intussusception. An
identifiable lead point such as a Meckel diverticulum or polyp is more likely
to be present in children over 2 years old. Intravenous fluid resuscitation is
likely to be required immediately, as there is often pooling of fluid in the
gut, which may lead to hypovolaemic shock.

Meckel diverticulum
Around 2% of individuals have an ileal
remnant of the vitello-intestinal duct, a Meckel diverticulum, which contains
ectopic gastric mucosa or pancreatic tissue. Most are asymptomatic but they may
present with severe rectal bleeding, which is classically neither bright red
nor true melaena. Other forms of presentation include intussusception, volvulus
around a band, or diverticulitis which mimics appendicitis. A technetium scan
will demonstrate increased uptake by ectopic gastric mucosa in 70% of case
visual pathway - Google Search
Basic visual pathway
In cases of paracetamol overdose, the
sulfate and glucuronide pathways become saturated, and more paracetamol is
shunted to the cytochrome P450 system to produce NAPQI. As a result,
hepatocellular supplies of glutathione become depleted, as the demand for
glutathione is higher than its regeneration.[28] NAPQI therefore remains in its
toxic form in the liver and reacts with cellular membrane molecules, resulting
in widespread hepatocyte damage and death, leading to acute hepatic
necrosis.[3][29] In animal studies, hepatic glutathione must be depleted to
less than 70% of normal levels before hepatotoxicity occurs.[25]
pcm poisonin
A paracetamol level drawn in the first four
hours after ingestion may underestimate the amount in the system because
paracetamol may still be in the process of being absorbed from the
gastrointestinal tract. Therefore, a serum level taken before 4 hours is not
recommended.[1

Diagnosis
A person's history of taking paracetamol is
somewhat accurate for the diagnosis.[30] The most effective way to diagnose
poisoning is by obtaining a blood paracetamol level. A drug nomogram developed
in 1975, called the Rumack-Matthew nomogram, estimates the risk of toxicity
based on the serum concentration of paracetamol at a given number of hours
after ingestion.[4] To determine the risk of potential hepatotoxicity, the
paracetamol level is traced along the nomogram. Use of a timed serum
paracetamol level plotted on the nomogram appears to be the best marker
indicating the potential for liver injury.[1
pcm poisoning
Clinical or biochemical evidence of liver
toxicity may develop in one to four days, although, in severe cases, it may be
evident in 12 hours.[31] Right-upper-quadrant tenderness may be present and can
aid in diagnosis. Laboratory studies may show evidence of hepatic necrosis with
elevated AST, ALT, bilirubin, a
pcm poisoning
Paracetamol may be quantified in blood,
plasma, or urine as a diagnostic tool in clinical poisoning situations or to
aid in the medicolegal investigation of suspicious deaths. The concentration in
serum after a typical dose of paracetamol usually peaks below 30 mg/l, which
equals 200 µmol/L.[34] Levels of 30–300 mg/L (200-2000 µmol/L) are often
observed in overdose patients. Postmortem blood levels have ranged from 50–400
mg/L in persons dying due to acute overdosage.
acetyl cystine for pcm poisoning
Intravenous acetylcysteine is given as a
continuous infusion over 20 hours for a total dose 300 mg/kg. Recommended
administration involves infusion of a 150 mg/kg loading dose over 15 to 60
minutes, followed by a 50 mg/kg infusion over four hours;
Acetylcysteine, also called
N-acetylcysteine or NAC, works to reduce paracetamol toxicity by replenishing
body stores of the antioxidant glutathione.
Cysteamine and methionine have also been
used to prevent hepatotoxicity,[58][59] although studies show that both are
associated with more adverse effects than acetylcysteine.[11] Additionally,
acetylcysteine has been shown to be a more effective antidote, particularly in
patients presenting greater than 8 hours post-ingestion.
Gastric decontamination
In adults, the initial treatment for
paracetamol overdose is gastrointestinal decontamination. Paracetamol
absorption from the gastrointestinal tract is complete within two hours under normal
circumstances
What is Lamictal?
Lamictal (lamotrigine) is an anti-epileptic
medication, also called an anticonvulsant.
Lamictal is used either alone or in
combination with other medications to treat epileptic seizures in adults and
children. Lamotrigine is also used to delay mood episodes in adults with
bipolar disorder (manic depression).
A positive Pemberton's sign is indicative
of superior vena cava syndrome (SVC), commonly the result of a mass in the
mediastinum. Although the sign is most commonly described in patients with
substernal goiters whe
carbimazole side effect
Whilst rashes and pruritus are common,
these can often be treated with antihistamines without stopping the
carbimazole. For those patients where sensitivity reactions can not be
controlled, propylthiouracil may be used as an alternative; cross-sensitivity
between these drugs is rare.
Its most serious rare side effect is bone
marrow suppression causing neutropenia and agranulocytosis. This may occur at
any stage during treatment and without warning; monitoring of white cell count
is not useful. Patients are advised to immediately report symptoms of
infection, such as sore throat or fever, so that a full blood count test may be
arranged. If this confirms a low neutrophil count, discontinuation of the drug
leads to recovery. However failure to report suggestive symptoms or delays in
considering the possibility of immunosuppression and its testing, can lead to
fatalities.
Catscratch disease (CSD), also known as
catscratch fever or subacute regional lymphadenitis, is a bacterial infection
affecting lymph nodes that drain the sites of inoculation. Bartonella henselae,
a gram-negative rod, is considered the principal etiologic agent.[1, 2] CSD is
one of the most common causes of chronic lymphadenopathy in children and
adolescents.
Patients with CSD usually have a history of
sustaining a scratch or bite from a cat (typically a kitten). The initial
symptom is formation of a papule at the inoculation site, followed by solitary
or regional lymphadenopathy within 1-2 weeks (see the images below). In most
patients, the disease resolves spontaneously within 2-4 months.
