MELENA
https://t.me/medicina_free

and symptoms include painful dysphagia, anorexia, and regurgitation.
◆ Esophageal varices (ruptured). This life-
threatening disorder can produce melena, hematochezia, and hematemesis. Melena is preceded by signs of shock, such as tachycardia, tachypnea, hypotension, and cool, clammy skin. Agitation or confusion signals developing he­patic encephalopathy.
◆ Gastric cancer. Melena and altered bowel
habits may occur late with this uncommon can­cer. More common findings include insidious onset of upper abdominal or retrosternal dis­comfort and chronic dyspepsia, which are unre­lieved by antacids and exacerbated by food. Anorexia and slight nausea often occur, along with hematemesis, pallor, fatigue, weight loss, and a feeling of abdominal fullness.
◆ Gastritis. Melena and hematemesis are
common. The patient may also experience mild epigastric or abdominal discomfort that’s exac­erbated by eating; belching; nausea; vomiting; and malaise.
◆ Malaria. Melena may accompany persistent
high fever and orthostatic hypotension in severe malaria. Other features include hemoptysis, vomiting, abdominal pain, diarrhea, oliguria, and headache, seizures, delirium, or coma. These findings are interspersed throughout the malarial paroxysm—chills, then high fever, and then profuse diaphoresis.
◆ Mallory-Weiss syndrome. This condition is
characterized by massive bleeding from the up­per GI tract due to a tear in the mucous mem­brane of the esophagus or the junction of the esophagus and the stomach. Melena and he­matemesis follow vomiting. Severe upper ab­dominal bleeding leads to signs and symptoms of shock, such as tachycardia, tachypnea, hy­potension, and cool, clammy skin. The patient may also report epigastric or back pain.
◆ Mesenteric vascular occlusion. This life-
threatening disorder produces slight melena with 2 to 3 days of persistent, mild abdominal pain. Later, abdominal pain becomes severe and may be accompanied by tenderness, disten­tion, guarding, and rigidity. The patient may also experience anorexia, vomiting, fever, and profound shock.
◆ Peptic ulcer. Melena may signal life-threat-
ening hemorrhage from vascular penetration. The patient may also develop decreased ap­petite, nausea, vomiting, hematemesis, hema­tochezia, and left epigastric pain that’s gnawing, burning, or sharp and may be described as heartburn or indigestion. With hypovolemic
shock come tachycardia, tachypnea, hypoten­sion, dizziness, syncope, and cool, clammy skin.
◆ Small-bowel tumors. These tumors may
bleed and produce melena. Other signs and symptoms include abdominal pain, distention, and increasing frequency and pitch of bowel sounds.
◆ Thrombocytopenia. Melena or hema-
tochezia may accompany other manifestations of bleeding tendency: hematemesis, epistaxis, petechiae, ecchymoses, hematuria, vaginal bleeding, and characteristic blood-filled oral bullae. Typically, the patient displays malaise, fatigue, weakness, and lethargy.
◆ Typhoid fever. Melena or hematochezia oc-
curs late in this disorder and may occur with hy­potension and hypothermia. Other late findings include mental dullness or delirium, marked ab­dominal distention and diarrhea, marked weight loss, and profound fatigue.
◆ Yellow fever. Melena, hematochezia, and he-
matemesis are ominous signs of hemorrhage, a classic feature, which occurs along with jaun­dice. Other findings include fever, headache, nausea, vomiting, epistaxis, albuminuria, pe­techiae and mucosal hemorrhage, and dizziness.
O
THER CAUSES
◆ Drugs and alcohol. Aspirin, other nons-
teroidal anti-inflammatories, or alcohol can cause melena as a result of gastric irritation.
S
PECIAL CONSIDERATIONS
Monitor vital signs, and look closely for signs of hypovolemic shock. For general comfort, en­courage bed rest, and keep the patient’s peri­anal area clean and dry to prevent skin irritation and breakdown. A nasogastric tube may be necessary to assist with drainage of gastric con­tents and decompression. Prepare him for diag­nostic tests, including blood studies, gas­troscopy or other endoscopic studies, barium swallow, and upper GI series. Prepare the pa­tient for blood transfusions as indicated by his hematocrit.
P
EDIATRIC POINTERS
Neonates may experience melena neonatorum due to extravasation of blood into the alimenta­ry canal. In older children, melena usually re­sults from peptic ulcer, gastritis, or Meckel’s di­verticulum.
G
ERIATRIC POINTERS
In elderly patients with recurrent intermittent GI bleeding without a clear etiology, angiography

or exploratory laparotomy should be considered once the risk from continued anemia is deemed to outweigh the risk associated with the proce­dures.
Menorrhagia
Abnormally heavy or long menstrual bleeding, menorrhagia may occur as a single episode or a chronic sign. In menorrhagia, bleeding is heav­ier than the patient’s normal menstrual flow; menstrual blood loss is 80 ml or more per monthly period. A form of dysfunctional uterine bleeding, menorrhagia can result from en­docrine and hematologic disorders, stress, and certain drugs and procedures.
EMERGENCY INTERVENTIONS Evaluate
hemodynamic status by taking orthostatic vital signs. Insert a large-gauge I.V. catheter to be­gin fluid replacement if the patient shows an in­crease of 10 beats/minute in pulse rate, a de­crease of 10 mm Hg in systolic blood pressure, or other signs of hypovolemic shock, such as pallor, tachycardia, tachypnea, and cool, clammy skin. Place the patient in a supine position with her feet elevated, and administer supplemental oxygen as needed.
Use menstrual pads to obtain information relat­ed to the quality and quantity of bleeding. Then prepare the patient for a pelvic examination to help determine the cause of bleeding.
H
ISTORY AND PHYSICAL
EXAMINATION
When the patient’s condition permits, obtain a history. Determine her age at menarche, the av­erage duration of menstrual periods, and the in­terval between them. Establish the date of the patient’s last menses, and ask about any recent changes in her normal menstrual pattern. Have the patient describe the character and amount of bleeding. For example, how many pads or tampons does the patient use? Has she noted clots or tissue in the blood? Also ask about the development of other signs and symptoms be­fore and during the menstrual period.
Next, ask if the patient is sexually active. Does she use a method of birth control? If so, what kind? Could the patient be pregnant? Be sure to note the number of pregnancies, the outcome of each, and any pregnancy-related complications. Find out the dates of her most recent pelvic examination and Papanicolaou smear and the details of any previous gyneco­logic infections or neoplasms. Also, be sure to
ask about any previous episodes of abnormal bleeding and the outcome of any treatment. If possible, obtain a pregnancy history of the pa­tient’s mother, and determine if the patient was exposed in utero to diethylstilbestrol. (This drug has been linked to vaginal adenosis.)
Be sure to ask the patient about her general health and medical history. Note particularly if the patient or her family has a history of thyroid, adrenal, or hepatic disease; blood dyscrasias; or tuberculosis because these may predispose the patient to menorrhagia. Also, ask about the pa­tient’s past surgical procedures and any recent emotional stress. Find out if the patient has un­dergone X-ray or other radiation therapy, be­cause this may indicate prior treatment for menorrhagia. Obtain a thorough drug and alco­hol history, noting the use of anticoagulants or aspirin. Perform a pelvic examination, and ob­tain blood and urine samples for pregnancy testing.
M
EDICAL CAUSES
◆ Blood dyscrasias. Menorrhagia is one of
several possible signs of a bleeding disorder. Other possible associated findings include epis­taxis, bleeding gums, purpura, hematemesis, hematuria, and melena.
◆ Endometriosis. Menorrhagia may be a sign
of this disorder, in which endometrial tissue is found outside the lining of the uterine cavity. However, the classic symptom is dysmenorrhea. Other findings depend on the location of the ec­topic tissue outside the uterus but may include dyspareunia, suprapubic pain, dysuria, nausea, vomiting, abdominal cramps, cyclic pelvic pain, and infertility. Often a tender, fixed adnexal mass is palpable on bimanual examination.
◆ Hypothyroidism. Menorrhagia is a common
early sign and is accompanied by such nonspe­cific findings as fatigue, cold intolerance, consti­pation, and weight gain despite anorexia. As hypothyroidism progresses, intellectual and mo­tor activity decrease; the skin becomes dry, pale, cool, and doughy; the hair becomes dry and sparse; and the nails become thick and brittle. Myalgia, hoarseness, decreased libido, and in­fertility commonly occur. Eventually, the patient develops a characteristic dull, expressionless face and edema of the face, hands, and feet.
Also, deep tendon reflexes are delayed, and bradycardia and abdominal distention may occur.
◆ Uterine fibroids. Menorrhagia is the most
common sign, but other forms of abnormal uterine bleeding as well as dysmenorrhea or
METRORRHAGIA
https://t.me/medicina_free
443
leukorrhea, can also occur. Possible related findings include abdominal pain, a feeling of ab­dominal heaviness, backache, constipation, uri­nary urgency or frequency, and an enlarged uterus, which is usually nontender.
O
THER CAUSES
◆ Drugs. Use of a hormonal contraceptive may
cause sudden onset of profuse, prolonged men­orrhagia. Anticoagulants have also been associ­ated with excessive menstrual flow. Injectable or implanted contraceptives may cause menor­rhagia in some women.
HERB ALERT Herbal remedies, such as
ginseng, can cause postmenopausal bleeding.
◆ Intrauterine devices. Menorrhagia can re-
sult from the use of intrauterine contraceptive devices.
S
PECIAL CONSIDERATIONS
Continue to monitor the patient closely for signs of hypovolemia. Encourage the patient to maintain adequate fluid intake. Monitor in­take and output, and estimate uterine blood loss by recording the number of sanitary nap­kins or tampons used during an abnormal pe­riod and comparing this with usage during a normal period. To help decrease blood flow, encourage the patient to rest and to avoid strenuous activities. Obtain blood samples for hematocrit, prothrombin time, partial throm­boplastin time, and international normalized ratio levels.
P
EDIATRIC POINTERS
Irregular menstrual function in young girls may be accompanied by hemorrhage and resulting anemia.
G
ERIATRIC POINTERS
In postmenopausal women, menorrhagia can­not occur. In such patients, vaginal bleeding is usually caused by endometrial atrophy. Malig­nancy must be ruled out.
Metrorrhagia
Metrorrhagia—uterine bleeding that occurs ir­regularly between menstrual periods—is usually light, although it can range from staining to he­morrhage. Usually, this common sign reflects slight physiologic bleeding from the endometri­um during ovulation. However, metrorrhagia may be the only indication of an underlying gy­necologic disorder and can also result from
stress, drugs, treatments, and intrauterine de­vices.
H
ISTORY AND PHYSICAL
EXAMINATION
Begin your evaluation by obtaining a thorough menstrual history. Ask the patient when she be­gan menstruating and about the duration of menstrual periods, the interval between them, and the average number of tampons or pads she uses. When does metrorrhagia usually occur in relation to her period? Does she experience oth­er signs or symptoms? Find out the date of her last menses, and ask about any other recent changes in her normal menstrual pattern. Get details of any previous gynecologic problems. If applicable, obtain a contraceptive and obstetric history. Record the dates of her last Papanico­laou smear and pelvic examination. Ask the pa­tient when she last had sex and whether or not it was protected. Next, ask about her general health and any recent changes. Is she under emotional stress? If possible, obtain a pregnancy history of the patient’s mother. Was the patient exposed in utero to diethylstilbestrol? (This drug has been linked to vaginal adenosis.)
Perform a pelvic examination if indicated, and obtain blood and urine samples for preg­nancy testing.
M
EDICAL CAUSES
◆ Cervicitis. This nonspecific infection may
cause spontaneous bleeding, spotting, or post­traumatic bleeding. Assessment reveals red, granular, irregular lesions on the external cervix. Purulent vaginal discharge (with or with­out odor), lower abdominal pain, and fever may occur.
◆ Dysfunctional uterine bleeding. Abnormal
uterine bleeding not caused by pregnancy or major gynecologic disorders usually occurs as metrorrhagia, although menorrhagia is possible. Bleeding may be profuse or scant, intermittent or constant.
◆ Endometrial polyps. In most patients, this
disorder causes abnormal bleeding, usually in­termenstrual or postmenopausal; however, some patients do remain asymptomatic.
◆ Endometriosis. Metrorrhagia (usually pre-
menstrual) may be the only indication of this disorder, or it may accompany cyclical pelvic discomfort, infertility, and dyspareunia. A ten­der, fixed adnexal mass may be palpable on bi­manual examination.
◆ Endometritis. This disorder causes metror-
rhagia, purulent vaginal discharge, and
444 MIOSIS
https://t.me/medicina_free
enlargement of the uterus. It also produces fever, lower abdominal pain, and abdominal muscle spasm.
◆ Gynecologic cancer. Metrorrhagia is com-
monly an early sign of cervical or uterine can­cer. Later, the patient may experience weight loss, pelvic pain, fatigue and, possibly, an ab­dominal mass.
◆ Syphilis. Primary- or secondary-stage
syphilis may cause metrorrhagia and postcoital bleeding. In primary syphilis, one or more usu­ally painless chancres erupt on the genitalia and possibly other areas. In secondary syphilis, gen­eralized lymphadenopathy may appear, along with a rash on the arms, trunk, palms, soles, face, and scalp.
◆ Uterine leiomyomas. Besides metrorrhagia,
these tumors may cause increasing abdominal girth and heaviness in the abdomen, constipa­tion, and urinary frequency or urgency. The pa­tient may report pain if the uterus attempts to expel the tumor through contractions and if the tumors twist or necrose after circulatory occlu­sion or infection, but many women with leio­myomas are asymptomatic.
◆ Vaginal adenosis. This disorder commonly
produces metrorrhagia. Palpation reveals roughening or nodules in affected vaginal areas.
O
THER CAUSES
◆ Drugs. Anticoagulants and oral, injectable,
or implanted contraceptives may cause metror­rhagia.
HERB ALERT Herbal remedies, such as
ginseng, can cause postmenopausal bleeding.
◆ Surgery and procedures. Cervical coniza-
tion and cauterization may cause metrorrhagia.
S
PECIAL CONSIDERATIONS
Encourage bed rest to reduce bleeding. Give an analgesic for discomfort.
Miosis
Miosis—pupillary constriction caused by con­traction of the sphincter muscle in the iris— occurs normally as a response to fatigue, in­creased light, or administration of a miotic; as part of the eye’s accommodation reflex; and as part of the aging process (pupil size steadily de­creases from adolescence to about age 60). However, it can also stem from an ocular or neurologic disorder, trauma, use of a systemic drug, or contact lens overuse. A rare form of
miosis—Argyll Robertson pupils—can stem from tabes dorsalis and diverse neurologic disorders. Occurring bilaterally, these miotic (often pin­point), unequal, and irregularly shaped pupils don’t dilate properly with mydriatic use and fail to react to light, although they do constrict on accommodation.
H
ISTORY AND PHYSICAL
EXAMINATION
Begin by asking the patient if he has experi­enced other ocular symptoms, and have him de­scribe their onset, duration, and intensity. Does he wear contact lenses? During your history, be sure to ask about trauma, serious systemic dis­ease, and use of topical and systemic drugs.
Next, perform a thorough eye examination. Test visual acuity in each eye, with and without correction, paying particular attention to blurred or decreased vision in the miotic eye. Examine and compare both pupils for size (many persons have a normal discrepancy), color, shape, reac­tion to light, accommodation, and consensual light response. Examine both eyes for additional signs, and then evaluate extraocular muscle function by assessing the six cardinal fields of gaze.
M
EDICAL CAUSES
◆ Cerebrovascular arteriosclerosis. Miosis is
usually unilateral, depending on the site and ex­tent of vascular damage. Other findings include visual blurring, slurred speech or possibly apha­sia, loss of muscle tone, memory loss, vertigo, and headache.
◆ Cluster headache. Ipsilateral miosis, tear-
ing, conjunctival injection, and ptosis com­monly accompany a severe cluster headache, along with facial flushing and sweating, brady­cardia, restlessness, and nasal stuffiness or rhinorrhea.
◆ Corneal foreign body. Miosis in the affected
eye occurs with pain, a foreign-body sensation, slight vision loss, conjunctival injection, photo­phobia, and profuse tearing.
◆ Corneal ulcer. Miosis in the affected eye ap-
pears with moderate pain, visual blurring and possibly some vision loss, and diffuse conjuncti­val injection.
◆ Horner’s syndrome. Moderate miosis is
common in this neurologic syndrome and oc­curs ipsilaterally to the spinal cord lesion. Relat­ed ipsilateral findings include a sluggish pupil­lary reflex, slight enophthalmos, moderate ptosis, facial anhidrosis, transient conjunctival injection, and vascular headache. When the
MOON FACE
https://t.me/medicina_free
445
syndrome is congenital, the iris on the affected side may appear lighter.
◆ Hyphema. Usually the result of blunt trauma,
hyphema can cause miosis with moderate pain, visual blurring, diffuse conjunctival injection, and slight eyelid swelling. The eyeball may feel harder than normal.
◆ Iritis (acute). Miosis typically occurs in the
affected eye along with decreased pupillary re­flex, severe eye pain, photophobia, visual blur­ring, conjunctival injection and, possibly, pus accumulation in the anterior chamber. The eye appears cloudy, the iris bulges, and the pupil is constricted on ophthalmic examination.
◆ Neuropathy. Two forms of neuropathy occa-
sionally produce Argyll Robertson pupils. With diabetic neuropathy, related effects include paresthesia and other sensory disturbances, ex­tremity pain, orthostatic hypotension, impo­tence, incontinence, and leg muscle weakness and atrophy.
With alcoholic neuropathy, related effects in­clude progressive, variable muscle weakness and wasting, various sensory disturbances, and hypoactive deep tendon reflexes.
◆ Parry-Romberg syndrome. This facial
hemiatrophy typically produces miosis, sluggish pupillary reflexes, enophthalmos, nystagmus, ptosis, and different-colored irises.
◆ Pontine hemorrhage. Bilateral miosis is
characteristic, along with rapid onset of coma, total paralysis, decerebrate posture, absent doll’s eye sign, and a positive Babinski’s sign.
◆ Tabes dorsalis. This tertiary form of syphilis
is marked by Argyll Robertson pupils, a wide base ataxic gait, paresthesia, loss of propriocep­tion, analgesia, thermanesthesia, Charcot’s joints, incontinence and, possibly, impotence.
◆ Uveitis. Anterior uveitis commonly produces
miosis in the affected eye, moderate-to-severe eye pain, severe conjunctival injection, photo­phobia, and pus in the anterior chamber.
With posterior uveitis, miosis is accompanied by gradual onset of eye pain, photophobia, visu­al floaters, visual blurring, conjunctival injection and, commonly, distorted pupil shape.
O
THER CAUSES
◆ Chemical burns. An opaque cornea may
make miosis hard to detect. However, chemical burns may also cause moderate-to-severe pain, diffuse conjunctival injection, inability to keep the eye open, visual blurring, and blistering.
◆ Drugs. Such topical drugs as acetylcholine,
carbachol, echothiophate iodide, and pilo­carpine are used to treat eye disorders specifi-
cally for their miotic effect. Such systemic drugs as barbiturates, cholinergics, anticholinesteras­es, clonidine hydrochloride (overdose), opiates, and reserpine also cause miosis, as does deep anesthesia.
S
PECIAL CONSIDERATIONS
Because any ocular abnormality can be a source of fear and anxiety, reassure and support the patient. Clearly explain any diagnostic tests ordered, which may include a complete oph­thalmologic examination or a neurologic workup.
P
EDIATRIC POINTERS
Miosis is common in neonates, simply because they’re asleep or sleepy most of the time. Bilat­eral miosis occurs with congenital microcoria, an uncommon bilateral disease transmitted as an autosomal dominant trait and marked by the absence of the dilator muscle of the pupil. At birth, these infants have pupils less than 2 mm and seem to gaze far away.
Moon face
Moon face, a distinctive facial adiposity, usually indicates hypercortisolism resulting from ec­topic or excessive pituitary production of corti­cotropin, adrenal adenoma or carcinoma, or long-term glucocorticoid therapy. Its typical characteristics include marked facial roundness and puffiness, a double chin, a prominent upper lip, and full supraclavicular fossae. Although the presence of moon face doesn’t help differentiate causes of hypercortisolism, it does indicate a need for diagnostic testing.
H
ISTORY AND PHYSICAL
EXAMINATION
Ask the patient when he first noticed his facial adiposity, and try to obtain a preonset photo­graph to help evaluate the extent of the change.
Ask about weight gain and any personal or family history of endocrine disorders, obesity, or cancer. Has the patient noticed any fatigue, irri­tability, depression, or confusion? If the patient is a female of childbearing age, determine the date of her last menses and whether she’s expe­rienced any menstrual irregularities.
If the patient is receiving a glucocorticoid, ask the name of the drug, dosage and schedule, route of administration, and reason for therapy. Also ask if the dosage has ever been modified and, if so, when and why.
446 MOUTH LESIONS
https://t.me/medicina_free
Take the patient’s vital signs, weight, and height. Assess the patient’s overall appearance for other characteristic signs of hypercorti­solism, including virilism in a female or gyneco­mastia in a male. Also assess for purple striae on the skin, muscle weakness due to loss of muscle mass from increased catabolism, and skeletal growth retardation in children.
M
EDICAL CAUSES
◆ Hypercortisolism. Moon face varies in
severity, depending on the degree of cortisol ex­cess and weight gain. The patient typically ex­hibits buffalo hump, truncal obesity with slender arms and legs, and thin, transparent skin with purple striae and ecchymoses. Other cushingoid features include acne, diaphoresis, fatigue, mus­cle wasting and weakness, poor wound healing, elevated blood pressure, and personality changes.
In addition to these findings, a woman may experience hirsutism and amenorrhea or oligomenorrhea; a man may experience gy­necomastia and impotence.
O
THER CAUSES
◆ Drugs. Most cases (more than 99%) of moon
face result from prolonged use of a glucocorti­coid, such as cortisone, dexamethasone, hydro­cortisone, or prednisone.
S
PECIAL CONSIDERATIONS
Relieve the patient’s concern about his body im­age by explaining that moon face and other dis­concerting cushingoid effects can usually be corrected by treating the underlying disorder or by discontinuing or modifying glucocorticoid therapy. Explain to the patient that he should only discontinue or modify glucocorticoid thera­py as directed by the physician.
Clearly explain to the patient any diagnostic tests ordered. These may include serum and urine 17-hydroxycorticosteroid studies; a 2-day, low-dose dexamethasone test followed by a 2­day, high-dose dexamethasone test; plasma cor­ticotropin studies; and a corticotropin-releasing hormone test.
Mouth lesions
Mouth lesions include ulcers (the most common type), cysts, firm nodules, hemorrhagic lesions, papules, vesicles, bullae, and erythematous le­sions. They may occur anywhere on the lips, cheeks, hard and soft palate, salivary glands, tongue, gingivae, or mucous membranes. Many are painful and can be readily detected. Some, however, are asymptomatic; when they occur deep in the mouth, they may be discovered only through a complete oral examination. (See Common mouth lesions.)
Mouth lesions can result from trauma, infec­tion, systemic disease, drug use, or radiation therapy.
H
ISTORY AND PHYSICAL EXAMINATION
Begin your evaluation with a thorough history. Ask the patient when the lesions appeared and whether he has noticed any pain, odor, or drainage. Also ask about associated complaints, particularly skin lesions. Obtain a complete drug history, including drug allergies and antibiotic use, and a complete medical history. Note espe­cially any malignancy, sexually transmitted dis­ease, I.V. drug use, recent infection, or trauma. Ask about his dental history, including oral hy­giene habits, frequency of dental examinations, and the date of his most recent dental visit.
Next, perform a complete oral examination, noting lesion sites and character. Examine the patient’s lips for color and texture. Inspect and palpate the buccal mucosa and tongue for color, texture, and contour; note especially any pain­less ulcers on the sides or base of the tongue. Hold the tongue with a piece of gauze, lift it, and examine its underside and the floor of the mouth. Depress the tongue with a tongue blade, and examine the oropharynx. Inspect the teeth and gums, noting missing, broken, or discolored teeth; dental caries; excessive debris; and bleed­ing, inflamed, swollen, or discolored gums.
Palpate the neck for adenopathy, especially in patients who smoke tobacco or use alcohol ex­cessively.
P
EDIATRIC POINTERS
Moon face is rare in children. In an infant or a young child, it usually indicates adrenal adeno­ma or carcinoma or, rarely, cri du chat syn­drome. After age 7, it usually indicates abnor­mal pituitary secretion of corticotropin in bilateral adrenal hyperplasia.
M
EDICAL CAUSES
◆ Acquired immunodeficiency syndrome
(AIDS). Oral lesions may be an early indication of the immunosuppression that’s characteristic of this disease. Fungal infections can occur, with oral candidiasis being the most common. Bacterial or viral infections of oral mucosa,

APHTHOUS STOMATITIS
tongue, gingivae, and periodontal tissue may also occur.
The primary oral neoplasm associated with AIDS is Kaposi’s sarcoma. The tumor is usually found on the hard palate and may appear ini­tially as an asymptomatic, flat or raised lesion, ranging in color from red to blue to purple. As these tumors grow, they may ulcerate and be­come painful.
◆ Actinomycosis (cervicofacial). This chronic
fungal infection typically produces small, firm, flat, usually painless swellings on the oral mu­cosa and under the skin of the jaw and neck. Swellings may indurate and abscess, producing fistulas and sinus tracts with a characteristic pu­rulent yellow discharge.
◆ Behçet’s syndrome. This chronic, progres-
sive syndrome that generally affects young males produces small, painful ulcers on the lips, gums, buccal mucosa, and tongue. In severe cases, the ulcers also develop on the palate, pharynx, and esophagus. The ulcers typically have a reddened border and are covered with a
GINGIVAL HYPERPLASIA
gray or yellow exudate. Similar lesions appear on the scrotum and penis or labia majora; small pustules or papules on the trunk and limbs; and painful erythematous nodules on the shins. Oc­ular lesions may also develop.
◆ Candidiasis. This common fungal infection
characteristically produces soft, elevated plaques on the buccal mucosa, tongue, and sometimes the palate, gingivae, and floor of the mouth; the plaques may be wiped away. The le­sions of acute atrophic candidiasis are red and painful. The lesions of chronic hyperplastic can­didiasis are white and firm. Localized areas of redness, pruritus, and foul odor may be present.
◆ Discoid lupus erythematosus. Oral lesions
are common, typically appearing on the tongue, buccal mucosa, and palate as erythematous ar­eas with white spots and radiating white striae. Associated findings include skin lesions on the face, possibly extending to the neck, ears, and scalp; if the scalp is involved, alopecia may re­sult. Hair follicles are enlarged and filled with scale.
448 MOUTH LESIONS
https://t.me/medicina_free
GENDER CUE This chronic, recurrent
disease is most common in women ages 30
to 40.
◆ Epulis (giant cell). This rare tumor or
growth occurs on the gingival or alveolar process, anterior to the molars. Dark red, pe­dunculated or sessile, and 0.5 to 1.5 cm in di­ameter, it commonly ulcerates to produce a concave defect in the underlying bone. Gingivae bleed easily with slight trauma.
◆ Erythema multiforme. This acute inflam-
matory skin disease produces sudden onset of vesicles and bullae on the lips and buccal mu­cosa. Also, erythematous macules and papules form symmetrically on the hands, arms, feet, legs, face, and neck and, possibly, in the eyes and on the genitalia. Lymphadenopathy may also occur. With visceral involvement, other findings include fever, malaise, cough, throat and chest pain, vomiting, diarrhea, myalgias, arthralgias, fingernail loss, blindness, hema­turia, and signs of renal failure.
◆ Gingivitis (acute necrotizing ulcerative).
This recurring periodontal condition causes a sudden onset of gingival ulcers covered with a grayish white pseudomembrane. Other findings include tender or painful gingivae, intermittent gingival bleeding, halitosis, enlarged lymph nodes in the neck, and fever.
◆ Gonorrhea. Painful lip ulcerations may oc-
cur, along with rough, reddened, bleeding gingi­vae (possibly necrotic and covered by a yellow­ish pseudomembrane), and a swollen, ulcerated tongue. Related effects vary. Most men develop dysuria, purulent urethral discharge, and a red­dened, edematous urinary meatus. Most women remain asymptomatic, but others develop in­flammation and a greenish yellow cervical dis­charge.
◆ Herpes simplex 1. With primary infection, a
brief period of prodromal tingling and itching, which is accompanied by fever and pharyngitis, is followed by eruption of small and irritating vesicles on any part of the oral mucosa, espe­cially the tongue, gums, and cheeks. Vesicles form on an erythematous base and then rup­ture, leaving a painful ulcer, followed by a yel­lowish crust. Other findings include submaxil­lary lymphadenopathy, increased salivation, halitosis, anorexia, and keratoconjunctivitis.
◆ Herpes zoster. This common viral infection
may produce painful vesicles on the buccal mu­cosa, tongue, uvula, pharynx, and larynx. Small red nodules often erupt unilaterally around the thorax or vertically on the arms and legs, and rapidly become vesicles filled with clear fluid or
pus; vesicles dry and form scabs about 10 days after eruption. Fever and general malaise ac­company pruritus, paresthesia or hyperesthesia, and tenderness along the course of the involved sensory nerve.
◆ Inflammatory fibrous hyperplasia. This
painless nodular swelling of the buccal mucosa typically results from cheek trauma or irritation and is characterized by pink, smooth, peduncu­lated areas of soft tissue.
◆ Leukoplakia, erythroplakia. Leukoplakia is
a white lesion that cannot be removed simply by rubbing the mucosal surface—unlike candidi­asis. It may occur in response to chronic irrita­tion from dentures or tobacco or pipe smoking, or it may represent dysplasia or early squamous cell carcinoma.
Erythroplakia is red and edematous and has a velvety surface. About 90% of all cases of ery­throplakia are either dysplasia or cancer.
◆ Lichen planus. Oral lesions develop on the
buccal mucosa or, less commonly, on the tongue as painless, white or gray, velvety, threadlike papules. These precede the eruption of violet papules with white lines or spots, usu­ally on the genitalia, lower back, ankles, and anterior lower legs; pruritus; nails with longitu­dinal ridges; and alopecia.
◆ Mucous duct obstruction. Obstruction pro-
duces a ranula—a painless, slow-growing mu­cocele on the floor of the mouth near the ducts of the submandibular and sublingual glands.
◆ Pemphigoid (benign mucosal). This rare
autoimmune disease is characterized by thick­walled vesicles on the oral mucous membranes, the conjunctiva and, less often, the skin. Mouth lesions typically develop months or even years before other manifestations and may occur as desquamative patchy gingivitis or as a vesicob­ullous eruption. Secondary fibrous bands may lead to dysphagia, hoarseness, and blindness. Recurrent skin lesions include vesicobullous eruptions, usually on the inguinal area and ex­tremities, and an erythematous, vesicobullous plaque on the scalp and face near the affected mucous membranes.
◆ Pemphigus. This chronic skin disease is
characterized by thin-walled vesicles and bullae that appear in cycles on skin or mucous mem­branes that otherwise appear normal. On the oral mucosa, bullae rupture, leaving painful le­sions and raw patches that bleed easily. Associ­ated findings include bullae anywhere on the body, denudation of the skin, and pruritus.
◆ Pyogenic granuloma. Commonly the result
of injury, trauma, or irritation, this soft, tender

nodule, papule, or polypoid mass of excessive granulation tissue usually appears on the gingi­vae but can also erupt on the lips, tongue, or buccal mucosa. The lesions bleed easily be­cause they contain many capillaries. The affect­ed area may be smooth or have a warty surface; erythema develops in the surrounding mucosa. The lesions may ulcerate, producing a purulent exudate.
◆ Squamous cell carcinoma. This is typically
a painless ulcer with an elevated, indurated bor­der. It may erupt in areas of leukoplakia and is most common on the lower lip, but it may also occur on the edge of the tongue or the floor of the mouth. High risk factors include chronic smoking and alcohol intake.
◆ Stomatitis (aphthous). This common dis-
ease is characterized by painful ulcerations of the oral mucosa, usually on the dorsum of the tongue, gingivae, and hard palate.
With recurrent aphthous stomatitis minor, the ulcer begins as one or more erosions covered by a gray membrane and surrounded by a red halo. It’s commonly found on the buccal and lip mucosa and junction, tongue, soft palate, phar­ynx, gingivae, and all places not bound to the periosteum.
With recurrent aphthous stomatitis major, large, painful ulcers commonly occur on the lips, cheek, tongue, and soft palate; they may last up to 6 weeks and leave a scar.
◆ Syphilis. Primary syphilis typically produces
a solitary painless, red ulcer (chancre) on the lip, tongue, palate, tonsil, or gingivae. The ulcer appears as a crater with undulated, raised edges and a shiny center; lip chancres may develop a crust. Similar lesions may appear on the fingers, breasts, or genitals, and regional lymph nodes may become enlarged and tender.
During the secondary stage, multiple painless ulcers covered by a grayish white plaque may erupt on the tongue, gingivae, or buccal mu­cosa. A macular, papular, pustular, or nodular rash appears, usually on the arms, trunk, palms, soles, face, and scalp; genital lesions usually subside. Other findings include generalized lymphadenopathy, headache, malaise, anorexia, weight loss, nausea, vomiting, sore throat, low fever, metrorrhagia, and postcoital bleeding.
At the tertiary stage, lesions (often chronic, painless, superficial nodules or deep granulo­matous lesions, called gummas) develop on the skin and mucous membranes, especially the tongue and palate.
◆ Systemic lupus erythematosus. Oral le-
sions are common and appear as erythematous
areas associated with edema, petechiae, and superficial ulcers with a red halo and a tendency to bleed. Primary effects include nondeforming arthritis, butterfly rash across the nose and cheeks, and photosensitivity.
◆ Trauma. The most common cause of oral le-
sions, trauma can produce ulcers anywhere in the mouth, especially on the tongue and buccal mucosa.
◆ Tuberculosis (oral mucosal). This rare dis-
order produces a painless ulcer (usually on the tongue) and, sometimes, caseation. Other find­ings include lymphadenopathy, fatigue, weak­ness, anorexia, weight loss, cough, low fever, and night sweats.
O
THER CAUSES
◆ Drugs. Various chemotherapeutic agents can
directly produce stomatitis. Also, allergic reac­tions to penicillin, sulfonamides, gold, quinine, streptomycin, phenytoin, aspirin, and barbitu­rates commonly cause lesions to develop and erupt. Inhaled steroids used for pulmonary dis­orders can also cause oral lesions.
◆ Orthodontics. The rubbing of orthodontic
equipment or prosthesis on the buccal mucosa may cause eroded, tender areas.
◆ Radiation therapy. Radiation therapy may
cause oral lesions.

PECIAL CONSIDERATIONS
If the patient’s mouth ulcers are painful, provide a topical anesthetic such as lidocaine.
P
EDIATRIC POINTERS
Causes of mouth ulcers in children include chickenpox, measles, scarlet fever, diphtheria, and hand-foot-and-mouth disease. In neonates, mouth ulcers can result from candidiasis or congenital syphilis.

ATIENT COUNSELING
Instruct the patient to avoid irritants, such as highly seasoned foods, citrus fruits, foods that contain salt or vinegar, alcohol, and tobacco. For mouth care, warn against using lemon­glycerin swabs because these can dry and irri­tate the lesions.
As appropriate, teach the patient proper oral hygiene. If toothbrushing is contraindicated, in­struct him to use a mouth rinse, such as normal saline solution or half-strength hydrogen perox­ide, and to avoid commercial mouthwashes that contain alcohol. Stress the importance of fre­quently changing to a new toothbrush. If the

Murmurs
Murmurs are auscultatory sounds heard within the heart chambers or major arteries. They’re classified by their timing and duration in the cardiac cycle, auscultatory location, loudness, configuration, pitch, and quality.
Timing can be characterized as systolic (be-
tween S throughout systole), diastolic (between S S tole; systolic and diastolic murmurs can be fur­ther characterized as early, middle, or late.
ness, such as the apex, the lower left sternal border, or an intercostal space. Loudness is graded on a scale of 1 to 6. A grade 1 murmur is very faint, only detected after careful ausculta­tion. A grade 2 murmur is a soft, evident mur­mur. Murmurs considered to be grade 3 are moderately loud. A grade 4 murmur is a loud murmur with a possible intermittent thrill. Grade 5 murmurs are loud and associated with a pal­pable precordial thrill. Grade 6 murmurs are loud and, like grade 5 murmurs, are associated with a thrill. A grade 6 murmur is audible even when the stethoscope is lifted from the thoracic wall.

Murmurs can reflect accelerated blood flow through normal or abnormal valves; forward blood flow through a narrowed or irregular valve or into a dilated vessel; blood backflow through an incompetent valve, septal defect, or patent ductus arteriosus; or decreased blood viscosity. Commonly the result of organic heart disease, murmurs occasionally may signal an emergency situation—for example, a loud holosystolic mur­mur after an acute myocardial infarction (MI) may signal papillary muscle rupture or ventricu­lar septal defect. Murmurs may also result from surgical implantation of a prosthetic valve. (See When murmurs mean emergency.)
Some murmurs are innocent, or functional. An innocent systolic murmur is generally soft, medi­um-pitched, and loudest along the left sternal bor­der at the second or third intercostal space. It’s ex­acerbated by physical activity, excitement, fever, pregnancy, anemia, or thyrotoxicosis. Examples include Still’s murmur in children and mammary souffle, often heard over either breast during late pregnancy and early postpartum. (See Detecting congenital murmurs, pages 451 and 452.)
H
ISTORY AND PHYSICAL EXAMINATION
If you discover a murmur, try to determine its type through careful auscultation. (See Identify- ing common murmurs, page 453.) Use the bell of your stethoscope for low-pitched murmurs; the diaphragm for high-pitched murmurs.
Next, obtain a patient history. Ask if the mur­mur is a new discovery, or if it has been known since birth or childhood. Find out if the patient has experienced any associated symptoms, par­ticularly palpitations, dizziness, syncope, chest
EMERGENCY INTERVENTION
When murmurs mean emergency
Although not normally a sign of an emergency, murmurs—especially newly developed ones— may signal a serious complication in patients with bacterial endocarditis or a recent acute myocardial infarction (MI).
When caring for a patient with known or suspected bacterial endocarditis, carefully aus­cultate for any new murmurs. Their develop­ment along with crackles, distended jugular veins, orthopnea, and dyspnea may signal heart failure.
Regular auscultation is also important in a patient who has experienced an acute MI. A loud decrescendo holosystolic murmur at the apex that radiates to the axilla and left sternal border or throughout the chest is significant, particularly in association with a widely split S and an atrial gallop (S4). This murmur, when accompanied by signs of acute pulmonary ede­ma, usually indicates the development of acute mitral insufficiency due to rupture of the chor­dae tendineae—a medical emergency.
