Once the inner cannula has been threaded into the proximal allopian tube, the guide wire is removed. Urol Clin North Am 39(3):273, 2012 Zullo F, Palomba S, Russo, et al: Laparoscopic colposuspension using sutures or Prolene meshes: a 3-year ollow-up. As another preoperative step, some suggest that estrogen may increase the vaginal wall thickness or easier dissection and suture placement. For example, i a patient develops language loss and a right homonymous hemianopia, a search or causes o le middle cerebral emboli should be per ormed. The 2 and 4 allelic variations o the apolipoprotein E gene are associated with increased risk o recurrent lobar hemorrhage and may there ore be markers o amyloid angiopathy. Additionally, super cial epigastric and super cial external pudendal vessels are divided as they are encountered. Supine hypertension is common in patients with orthostatic hypotension due to autonomic ai ure, a ecting over 50% o patients in some series. For example, en bloc pelvic resection combines low anterior resection with hysterectomy, bilateral salpingooophorectomy, and removal o surrounding peritoneum (Section 46-13, p. Constipation and straining are avoided, and stool so teners are usually prescribed. This abnorma ity is thought to impair bin ing with merosin an ea s to weakening o the ystrophin-g ycoprotein comp ex, instabi ity o the musc e membrane, an /or abnorma ities in musc e contraction. Physicians should inquire about when the patient typically goes to bed, when they all asleep and wake up, whether they awaken during sleep, whether they eel rested in the morning, and whether they nap during the day. Hematogenous abscesses are of en located at the junction o the gray and white matter and are of en poorly encapsulated. The reporte prevalence o epression in patients with diabetes mellitus varies rom 8 to 27%, with the severity o the moo state correlating with the level o hyperglycemia an the presence o iabetic complications. The decision to use anticoagulation or primary prevention is based primarily on risk actors (able 32-3). Occasionally, tremor can be severe and inter ere with eating, writing, and activities o daily 424 living. For most patients who present primarily with obstructive/transport loss a ecting the 262 nasal and paranasal regions. Dillo n this atlas comprises 48 cases to assist the clinician caring or patients with neurologic symptoms.

Vas dilatati n by dire t angi plasty appears t be permanent, all wing hypertensive therapy t be tapered s ner. Every e ort is made to encourage early ambulation as soon as the patient is stable. A red rubber catheter is inserted and withdrawn to make sure that the pouch can be easily accessed. A ter the peritoneum is entered, the abdomen is explored, bowel is packed rom the operating ield, and a sel -retaining abdominal wall retractor is placed. Advances in presurgical evaluation and microsurgical techniques have led to a steady increase in the success o epilepsy surgery.

T us, women are counseled regarding the possible need or suture release i severe buttock pain that radiates to the posterior thigh develops postoperatively. These changes increase the excitability o nociceptor terminals and lower their threshold or activation by mechanical, thermal, and chemical stimuli. This implies that sympathetic activity can activate undamaged nociceptors when in ammation is present. Histologically, thickened collagen bundles are seen in the deep dermis o the skins with increased numbers o brocytes and elastic bers. There ore, women with prior transmural uterine surgery are evaluated or type and location o uterine scar. Such presbyosmia helps to explain why many elderly report that ood has little f avor, a problem that can result in nutritional disturbances. Neurons in the ventrolateral preoptic nucleus, one o the key sleep-promoting sites, are lost during normal human aging, correlating with reduced ability to maintain sleep (sleep ragmentation). Other clinical eatures o alcohol withdrawal include anxiety, insomnia, and autonomic nervous system overactivity mani ested as tachycardia, tachypnea, elevated blood pressure, and ever. These patients may present clinically with prominent movement disorders (tremor, myoclonus) or parkinsonian eatures. Cognitive operations impaired by pre rontal cortex lesions o en are re erred to as "executive unctions. All three orms are associated with a ailure to ully dilute the urine and mount a water diuresis in the ace o hypotonic hyponatremia. In autoimmune sti -person syndrome, exaggerated lordosis o the lumbar spine and overactivation o antagonist muscles restrict trunk and lower-limb movement and result in a wooden or xed posture. Similarly, the water seal created between the hysteroscope and internal cervical os prevents leakage o uid into the vagina. Small hormone-secreting adenomas may cause signi cant clinical perturbations, whereas larger adenomas that produce less hormone may be clinically silent and remain undiagnosed (i no central compressive e ects occur). In bilateral optic neuropathy, no af erent pupil e ect is present i the optic nerves are af ecte equally. They may increase dyskinesia in levodopa-treated patients, but this can usually be controlled by down-titrating the dose o levodopa. A neuropathic component to the pain is indicated by evidence o nerve damage, such as sensory impairment, exquisitely sensitive skin (allodynia), weakness, and muscle atrophy, or loss o deep tendon re exes. Pathogenic prions are most toxic as oligomers and less toxic a ter polymerization into amyloid f brils. This may change in the uture when there is a disease-modi ying therapy and it is important to make the diagnosis as early as possible. Some patients may think that a short amount o sleep is normal or advantageous, and they may not appreciate their biological need or more sleep, especially i co ee and other stimulants mask the sleepiness. Like - ystrog ycan, the transmembrane sarcog ycan proteins a so bin to ystrophin; these ve proteins (esignate - through -sarcog ycan) comp ex tight y with each other. Exa les o associated injury include inor shoulder or li b trau a, ractures, yocardial in arction, or stroke. Ataxia may a so invo ve the head and trunk or the voice, producing a characteristic cerebe ar dysarthria (scanning speech). First, the assistant angles the uterus to the contralateral side o dissection using a uterine manipulator and/or a grasper holding one cornu. This photopsia is brie an is con ne to one eye, in contrast to the bilateral, prolonge scintillations o cortical migraine. It is important to note, however, that many drug-related e ects are long lasting and not reversed by short-term drug discontinuance. When con ronted with a case o laryngeal palsy, the physician must attempt to determine the site o the lesion. The uterine artery tie is placed as close as possible to its origin rom the internal iliac artery.

T reatment of refractory epilepsy Approximately one-third o patients with epilepsy do not respond to treatment with a single antiepileptic drug, and it becomes necessary to try a combination o drugs to control seizures. These treatments are also not recommended in guidelines rom the American College o Physicians and the American Pain Society. H wever, this is m re likely t prevent the mpli ati n pr l nged neur mus ular jun ti n bl kade than it is t prevent this my pathy. Many patients, however, do not lose consciousness a er a minor head injury but instead are dazed or con used, or eel stunned or "star struck," and the term concussion is now applied to all such cognitive and perceptual changes experienced a er a blow to the head. Binocular iplopia results rom a wi e range o processes: in ectious, neoplastic, metabolic, egenerative, in ammatory, an vascular.

Migraine aura can have prominent brainstem symptoms, and the terms basilar artery and basilar-type migraine have now been replaced by migraine with brainstem aura (able 34-1). Overcorrection o the urethrovesical angle has been suggested as a cause o these long-term urinary and prolapse complications. Other medications that are used include thalidomide, pe oxacin, o oxacin, spar oxacin, minocycline, and clarithromycin.

O en it is i cult to if erentiate papille ema rom other orms o optic isc e ema by un us examination alone. These aps provide supportive blood supply to de ects that develop in poorly vascularized or brotic tissue. It may rarely occur as a pure or pre ominantly autonomic neuropathy with cholinergic or a renergic ys unction at the pre- or postganglionic levels. This 17% absolute reduction in the surgical group is a 65% relative risk reduction avoring surgery (able 32-4). As the ull repertoire o human ion channels an relate proteins is i enti e, it is likely that a itional channelopathies will be iscovere. The surgeon dissects retroperitoneally atop the aorta to urther mobilize the duodenum and displace it cephalad. T us, a surgeon should be aware o recurrence rates quoted in the literature and his or her own personal rates. However, in the presence o in ammatory mediators, these a erents become sensitive to mechanical stimuli. In all circumstances, removal o diseased bowel and end-to-end anastomosis is pre erable. With bleeding controlled, a surgeon then assesses the vascular support to the ureter and other sidewall structures. Border zone territory in arctions can occur, especially in the setting o systemic hypotension during cardiac transplant surgery. An alternative way to test cold sensation is to touch a metal object, such as a tuning ork at room temperature, to the skin. Many o the me ical risks associate with bulimia nervosa parallel those o anorexia nervosa an are a irect consequence o purging, inclu ing ui an electrolyte isturbances an con uction abnormalities. The presence o known cerebrovascular disease is not a contraindication to treatment aimed at achieving normotension. Despite its popularity in the media, "brain training" has not been shown to slow decline in cognitive unction. A history o amenorrhea or galactorrhea should lead one to question whether a prolactin-secreting pituitary adenoma (or the polycystic ovary syndrome) is the source o headache. Regardless o the clinical circumstances, the same surgical principles apply during colostomy: adequate bowel mobilization, su cient blood supply, and a tension- ree tunnel through the abdominal wall without bowel constriction.

The opioid antagonist naloxone should be readily available whenever opioids are used at high doses or in patients with compromised pulmonary unction. In one systematic review, overall continence rates ranged rom 85 to 90 percent at 1 year and declined to 70 percent by 5 years (Lapitan, 2012). Epidemiologic studies have incriminated risk actors or this disease including exposure to pesticides and insecticides, smoking, and, in one report, service in the military. While these lesions may be an incidental nding, a substantial burden o white matter disease will ultimately impact cerebral control o locomotion. The digestive tract appears to be particularly susceptible to the e ects o cigarette smoking because cigarette smoking has been linked to esophageal, stomach, pancreatic, liver, and colorectal cancer. Last, concurrent hysterectomy eliminates the risk o uterine or cervical cancer and o postoperative hemato- or pyometra. Food and Drug Administration has warned that use o metoclopramide or more than 12 weeks increases the risk o D. Although apical prolapse recurrence is in requent, later prolapse o the anterior and posterior vaginal walls is more common. Neuro bromas are benign tumors o the nerve sheath that typica y arise rom the posterior root; when mu tip e, neuro bromatosis is the ike y etio ogy. Regardless o ovarian preservation, salpingectomy is now encouraged or all women undergoing hysterectomy (Society o Gynecologic Oncology, 2013). A utonomic nervous system testing Autonomic testing, inc ud- ing ti t-tab e testing, can be per ormed in specia ized centers (Chap. Dyspareunia is commonly attributed to the posterolateral de ection o the vaginal axis. However, the presence o abnormal brainstem signs does not always indicate that the primary lesion is in the brainstem because hemispheral masses can cause secondary brainstem damage by the earlier described transtentorial herniations. Resistance strength training can increase muscle mass and leg strength, even or people in their eighties and nineties. Long-term relapse prevention or opioid-dependent persons support o vital un tions, in luding intu ation i needed (Table 64-2). All ollow-up studies have demonstrated that this need or higher doses o alcohol to achieve e ects predicts uture heavy drinking, alcohol problems, and alcohol use disorders. On neuropathologic examination, there is selective loss o the large pyramidal cells in the precentral gyrus and degeneration o the corticospinal and corticobulbar projections. The requency o each condition depends on the age group under study, access o the group to medical care, country o origin, and perhaps racial or ethnic background. The subacute development o two or more o these ndings should increase the index o suspicion or spinal epidural abscess. I there is any valid suspicion or a leak, the distal rectum should be divided again and the anastomosis redone. Injury to the rectum or rectovaginal stula is another rare but potential complication. This is the last decision to be made be ore dividing the bowel and beginning steps o the operation that are irreversible. Because it inhibits an enzyme that is part o the normal metabolism o alcohol, it allows the buildup o acetaldehyde, which creates these unpleasant symptoms. Subtle abnormalities o attention, intellect, spontaneity, and memory return toward normal weeks or months a er the injury, sometimes abruptly. Persistent severe headache and repeated vomiting in the context o normal alertness and no ocal neurologic signs is usually benign, but C should be obtained and a longer period o observation is appropriate. The clinical picture may be homogeneous within a amily with dominantly inherited ataxia, but sometimes most af ected amily members show one characteristic syndrome, while one or several members have an entirely dif erent phenotype. De nitive treatment is based on the speci c tumor type and includes surgery, radiotherapy, and chemotherapy. Pain rom angina may be re erred to the head, probably by central connections o vagal a erents, and may present as exertional headache (cardiac cephalgia).

Inspection o the urethra is also essential and can be per ormed with the same 70-degree angle scope. The sensory neuronopathy runs its course in a ew weeks or months and stabilizes, leaving the patient disabled. Isolate trochlear nerve palsy results rom all the causes liste above or the oculomotor nerve except aneurysm. Prednisone or dexamethasone is given with anticysticidal therapy to reduce the host in ammatory response to degenerating parasites. Normal gait requires that multiple systems-including strength, sensation, and coordination- unction in a highly integrated ashion. Ep iscleritis this is an in ammation o the episclera, a thin layer o connective tissue between the conjunctiva an the sclera. With prompt diagnosis and treatment o spina epidura abscess, up to two-thirds o patients experience signi cant recovery. Fertil Steril 68:402, 1997 Sharp H: Assessment o new technology in the treatment o idiopathic menorrhagia and uterine leiomyomata. Strict attention to these seemingly straight orward steps ensures the best possible outcome. In hypervolemic hyponatremia, uid restriction is also appropriate and somewhat e ective i it can be maintained. Late in the illness, there may be urinary urgency and incontinence and sometimes ecal incontinence; sexual unction tends to be preserved. Because pain-transmission neurons can be activated by modulatory neurons, it is theoretically possible to generate a pain signal with no peripheral noxious stimulus. Agonal gasps are the result o lower brainstem (medullary) damage and are recognized as the terminal respiratory pattern o severe brain damage. In patients with more severe disability, the elderly, those with cognitive impairment, or those in whom the diagnosis is uncertain, most physicians would initiate therapy with levodopa. Comorbid substance abuse, most o en with alcohol or sedative/hypnotics, is also common, perhaps as an attempt to sel treat anxiety. These complications can be avoi e in most patients by a ministration o panretinal laser photocoagulation at the appropriate point in the evolution o the isease. Note the reduced striatal uptake o tracer, which is most pronounced in the posterior putamen and tends to be asymmetric. A variety o car iovascular, respiratory, en ocrine, an neurologic con itions can present with anxiety as the chie complaint. Neuro ogica y, it most common y pro uces a spina cor syn rome (mye opathy) af ecting the posterior co umns (oss o vibration an position sense) an corticospina tracts (hyperactive ten on re exes with Babinski signs); it a so amages periphera nerves (neuropathy), resu ting in sensory oss with epresse ten on re exes. This periphera nerve hyperexcitabi ity is me iate by antibo ies that target vo tage-gate potassium channe s. Muscle contraction has been considered to be a eature that distinguishes H rom migraine, but there appear to be no di erences in contraction between the two headache types. Derm o id cysts Like epidermoid cysts, dermoid cysts arise rom epithelial cells that are retained during closure o the neural tube. For ischemic stroke, several strategies can reduce the risk o subsequent stroke in all patients, while other strategies are e ective or patients with speci c causes o stroke such as cardiac embolus and carotid atherosclerosis. Sleep onset begins in local brain regions be ore gradually sweeping over the entire brain as sensory thresholds rise and consciousness is lost. Patients can drink only clear liquids the day be ore surgery and complete one or two enemas the night prior to or the morning o surgery. Migraine patterns usually last longer an are perceive in both eyes, whereas amaurosis ugax is brie er an occurs in only one eye. Flin t Be al the human nervous system is the organ o consciousness, cognition, ethics, an behavior; as such, it is the most intricate structure known to exist. A voiding trial is per ormed prior to discharge as all patients can experience urinary retention rom a levator myorrhaphy or perineorrhaphy. This gure illustrates how inter erence with any one o these actors may not necessarily stop the cell death cascade.

A ter exploration and determination o tumor resectability, it can be lengthened as needed. Pro ound hearing loss and severe vertigo are associated with temporal bone ractures involving the inner ear. Because a smaller diameter operative hysteroscope is required or tubal cannulation, cervical dilatation may not be required. Fatigue can be exacerbated by e evated temperatures, depression, expending exceptiona e ort to accomp ish basic activities o dai y iving, or s eep disturbances. Fever, constant pain unin uenced by position, sphincter abnormalities, or signs o spinal cord disease suggest an etiology other than lumbar disk disease. Within a ew days, this swelling may be counteracted by inactivation or elimination o intracellular solutes, resulting in the remission o symptoms even though the hyponatremia persists. The re an green cone pigments are enco e on the X chromosome, an the blue cone pigment on chromosome 7. I sympt mati vas spasm persists despite ptimal medial therapy, intraarterial vas dilat rs and per utane us transluminal angi plasty are nsidered. Provocative tests with g ucose an insu in to estab ish a iagnosis are usua y not necessary an are potentia y hazar ous. Correct positioning prevents nerve injury and allows access to the vagina or manipulation and examination, to the bladder or cystoscopy, and to the abdomen or proper sel retaining retractor placement. Perioperatively, no speci c patient preparation is required, as midurethral sling release is a minor surgical procedure. The serotonin precursor 5-hydroxitriptophan (plus carbidopa) may be use ul in some cases o postanoxic myoclonus. Scissor blades are opened and closed, while the surgeon exerts gentle Anterior Colporrhaphy the anterior vaginal wall is the most requent site o clinically recognized prolapse (Brincat, 2010). In some women, pelvic support takes precedence, and coital unction is also not desired. For this reason, concurrent laparoscopy in some cases is recommended to help in orm a surgeon as to the proximity o the uterine serosa. A special pattern o "alpha coma," de ned by widespread, variable 8- to 12-Hz activity, super cially resembles the normal rhythm o waking but, unlike normal activity, is not altered by environmental stimuli. It may also be necessary to use an introducer with the atraumatic needle, which does not have the customary cutting, beveled tip. Once this medial dissection is completed, brovascular attachments between the sigmoid colon mesentery and le t side o the distal aorta are sharply transected. Any attempt to con ront the patient usually creates a sense o humiliation an causes the patient to aban on treatment rom that caregiver. Sigmoid conduits are generally less desirable due to preexisting radiation damage and proximity to a concurrent colostomy site. The ew contro e stu ies comparing rugs against behaviora intervention in the treatment o agitation suggest mi e cacy with signi cant si e ef ects re ate to s eep, gait, an car iovascu ar comp ications, inc u ing an increase risk o eath. There are many etiologies o hypernatremia including, most commonly, renal and extrarenal losses o water. The chelating carrier molecule or gadolinium can be classi ed by whether it is macrocyclic or has linear geometry and whether it is ionic or nonionic. Symptoms usually begin in the third or ourth decade, presenting as progressive spastic weakness beginning in the distal lower extremities; however, there are variants with onset so early that the di erential diagnosis includes cerebral palsy. Without this in ormation, many patients with dementia or depression may be mistaken as delirious during a single initial evaluation. Patients may present with seizure, hemiparesis, or aphasia as a mani estation o these ocal de cits or with a picture more inf uenced by the accompanying cerebral edema and characterized by con usion, dementia, and lethargy, which can progress to coma. One typically also has symptoms including jaw claudication, di use myalgias, and potential visual symptoms. Activation o complement initiates a characteristic vesicular disintegration o the myelin sheath and also leads to recruitment o activated macrophages, which participate in damage to myelin and axons.

Coronal di usion-weighted image demonstrates high signal intensity indicating restricted di usion involving the right medial temporal lobe and hippocampus (arrows) as well as subtle involvement o the le t in erior temporal lobe (arrowhead). Patients may present with diplopia, ptosis, ophthalmoplegia, and decreased acial sensation, depending on the extent o neural damage. Recurrent thoughts o death (not just ear o dying), recurrent suicidal ideation without a specif c plan, or a suicide attempt or a specif c plan or committing suicide B. Most o the new drugs that have become available in the past decade are used as add-on or alternative therapy, although many are now being used as rst-line monotherapy. Axons o the pyramidal or corticospinal system descend through the brainstem in the cerebral peduncle o the midbrain, the basis pontis, and the medullary pyramids. Optical coherence tomography reveals correspon ing loss o bers along the arcuate pathways in the nerve ber layer. Studies with rodents demonstrate that oral in ection with prions can occur, but the process is ine cient compared to intracerebral inoculation. At our institution, we generally continue catheterization or at least 2 weeks ollowing vesicovaginal stula repair. The stoma site or a sigmoid colostomy is selected based on an imaginary line drawn rom the umbilicus to the le t-sided anterior superior iliac spine. No electrosurgery is required or tubal cannulation, thus saline is the pre erred medium. Paraaortic lymphadenectomy can be perormed via laparotomy or minimally invasive approach (p. This technique has proved use ul to neuroscientists interested in interrogating the localization o certain brain unctions. For many in ivi uals, particularly those with time-consuming compulsions, behavior therapy will result in as much improvement as that a or e by me ication. Meningiomas and neuro bromas account or most o these, with occasiona cases caused by chordoma, ipoma, dermoid, or sarcoma. This artery and vein are large and are separately doubly clamped, cut, and ligated with 0-gauge delayed-absorbable suture.

High-resolution magnetic resonance angiography is use ul preoperatively to visualize the relationships between the h cranial nerve root and nearby blood vessels. Over time, synthetic bers within the microinsert incite a chronic in ammatory response and a local tissue ingrowth rom the surrounding tube. In those with de ects, it may be attenuated, torn in the middle, or completely avulsed rom the sidewall. Physicians may nee to switch the patient to a benzo iazepine with a longer hal -li e or use an a junctive me ication such as a beta blocker or carbamazepine, be ore attempting to iscontinue the benzo iazepine.

These estimates emphasize the remarkably high requency o this cognitive syndrome in older patients, a population expected to grow in the upcoming decades. Likewise, conductive hearing loss associated with otosclerosis can be treated by stapedectomy, which is successul in >95% o cases. The second hemostat is placed at a 30-degree angle so that the tips meet, but Metzenbaum scissors have room to cut between the two clamps. Whether the cumulative sleep deprivation that is common in modern society contributes to clinically apparent atigue is not known (Chap. Removal o two lesions or a single symptomatic mass, particularly i compressing the ventricular system, can also be use ul. Weakness rom involvement o upper motor neurons occurs particularly in the extensors and abductors o the upper limb and the exors o the lower limb. In general, the extent o pelvic lymphadenectomy will depend on the clinical circumstances, such as degree o associated scarring and patient habitus. Overlooking the importance o this decision can lead to various otherwise preventable complications intraoperatively and postoperatively. Ovarian metastasis is rare with early-stage cervical cancer, and particularly with squamous cell carcinoma. The prognosis o electrocerebral silence, when recorded using an adequate technique, there ore depends on the clinical context in which it is ound. Electrosurgical energy use is minimized to reduce risks o delayed thermal bladder injury. In an individual without any prior history o alcohol intake, what serum concentration o ethanol (in g/dL) would likely result in death Children o alcoholics have a 10- old higher risk o alcohol abuse and dependence even i adopted early in li e and raised by nonalcoholics. The most common primary tumors are cavernous hemangioma, lymphangioma, neuro broma, schwannoma, ermoi cyst, a enoi cystic carcinoma, optic nerve glioma, optic nerve meningioma, an benign mixe tumor o the lacrimal glan. Distal dysesthesias can also be an early event in an evolving polyneuropathy or may herald a myelopathy, such as rom vitamin B12 de ciency. The lesions (usually a combination o damage to the le occipital cortex and to a posterior sector o the corpus callosum-the splenium) interrupt the ow o visual input into the language network. Cluster headache is associated with ipsilateral symptoms o cranial parasympathetic autonomic activation: conjunctival injection or lacrimation, rhinorrhea or nasal congestion, or cranial sympathetic dys unction such as ptosis. Occasionally an immunosuppressive medication, such as azathioprine or methotrexate, needs to be added to maintain an initial response to glucocorticoids. In addition to correcting apical prolapse, the gra t also covers proximal portions o the anterior and posterior vaginal walls. A low response per drink is observed early in the drinking career and be ore alcohol use disorders develop. Electrosurgical blade dissection proceeds dorsally until all implants are contained within the peritoneal specimen. With the ureter still held laterally, the surgeon irst establishes the medial border o the right paraaortic nodal group. A vice about stress re uction an cautions that alcohol may exacerbate epressive symptoms an impair rug response are help ul. Cocaine toxicity produces a hyperadrenergic state characterized by hypertension, tachycardia, tonic-clonic seizures, dyspnea, and ventricular arrhythmias. When the cortical region cannot be removed, multiple subpial transection, which disrupts intracortical connections, is sometimes used to prevent seizure spread. These complications may develop more requently in women with obesity, prior pelvic in ections, and previous abdominal surgery, in whom surgery may be more di cult (Cohn, 2000). These conduits are o ten pre erable or medically compromised patients, the elderly, and anyone with a short li e expectancy. For example, patients with weakness in chewing and swallowing may bene t by taking the medication be ore meals so that peak strength coincides with mealtimes. Mille r Dementia, a syndrome with many causes, a ects >5 million people in the United States and results in a total annual health care cost between $157 and $215 billion. Although neonatal hemorrhage is uncommon, the mother should be treated with oral vitamin K (20 mg/d, phylloquinone) in the last 2 weeks o pregnancy, and the in ant should receive intramuscular vitamin K (1 mg) at birth. The iagnosis requires slitlamp examination to i enti y in ammatory cells oating in the aqueous humor or eposite on the corneal en othelium (keratic precipitates).
