The nature of the pain is the key symptom of the disease: • Pain, pressure or discomfort perceived to be related to the bladder, increasing with increasing bladder content. Cystoscopy Non-ulcer disease displays a normal bladder mucosa at initial cystoscopy. The observation of glomerulations may however not always be constant over time (32). Some authors maintain that cystoscopy with hydrodistension provides little useful information in addition to the history and physical examination findings (33, 34). Glomerulations may be involved in the disease mechanism, because such findings are highly associated with overexpression of angiogenic growth factors in the bladder and neovascularisation (36). Important differential diagnoses to exclude by histological examination are carcinoma in situ and tuberculous cystitis. Symptom scores may help to describe symptoms in an individual patient and as outcome measures. It is an attractive idea to support or, even better, to confirm the clinical diagnosis using a biological marker. It is therefore recommended to adapt A diagnostic procedures to each patient and aim at identifying them.

Chronic prostatitis/chronic pelvic pain syndrome and interstitial cystitis: are they related Antiproliferative factor, heparin-binding epidermal growth factor-like growth factor, and epidermal growth factor in men with interstitial cystitis versus chronic pelvic pain syndrome. Pain is often a dominant symptom, therefore, many patients try commonly used analgesics at some stage of the disease. Short-term opioids may be indicated for breakthrough or exacerbated pain and periodic flare-ups. Long-term opioids may be considered after all other available therapeutic options have been exhausted. Urologists should obtain informed consent, arrange for regular follow-up, and be prepared to recognise opioid-induced side effects (1). Reports on outcome with corticosteroid therapy have been both promising (2) and discouraging (3). Histamine receptor antagonists have been used to block the H1 (5) as well as the H2 (6) receptor subtypes, with variable results. Hydroxyzine hydrochloride (Atarax) is usually given, starting with 25 mg at bedtime, increasing to 50 mg/day, or if tolerated, 75 mg. The most common side effects are sedation and generalised weakness, which usually resolve after a period of treatment. However, the study was underpowered, which may be why it failed to demonstrate a statistically significant outcome for either drug compared to placebo. In a subsequent, prospective, open-label study (15), a response rate of 64% with an overall mean dose of 55 mg was seen with long term amitriptyline for 20 months. A multicentre, randomised, double-blind, placebo-controlled clinical trial comparing amitriptyline and placebo plus behavioural modification in 273 patients concluded that amitriptyline may be beneficial at 50 mg/daily (16). Nortriptyline is sometimes considered in place of amitriptyline when drowsiness is the limiting factor. Pentosan polysulphate sodium (Elmiron) has been evaluated in double-blind, placebo-controlled studies. However, treatment response was not dose-dependent but related more to treatment duration. The effect was maintained throughout 5 years follow-up, with 20/23 patients reporting no bladder pain. CyA was superior to pentosan polysulphate sodium in all clinical outcome parameters, with the frequency of micturition significantly reduced in CyA-treated patients, and clinical global response rates of 75% (CyA) and 19% (pentosan polysulphate sodium) (P < 0. During CyA therapy, careful follow-up is mandatory, including regular blood pressure measurement and serum creatinine. Pregabalin is an alpha (2)-delta ligand that binds to and modulates voltage-gated calcium channels, exerting its intended effect to reduce neuropathic pain (30). It was first tested in a small open-label study of 29 patients, with hopeful results (32).

Pilot study of sequential oral antibiotics for the treatment of interstitial cystitis. Alkalisation of lidocaine before intravesical application improves pharmacokinetics (3). A double-blind placebo-controlled study (6) was performed in 20 patients, of whom 10 received intravesical pentosan polysulphate sodium (300 mg in 50 mL 0. Bladder capacity showed a significant increase only in patients treated with pentosan polysulphate sodium. At 18 months, symptoms were relieved in eight patients, who were still receiving pentosan polysulphate sodium instillation, and in four patients not receiving the drug. All subjects continued to receive oral pentosan polysulphate sodium for a further 12 weeks.

Hallock176 proposed a useful classification of com Calderon antibiotics for recurrent uti in pregnancy roxithromycin 150 mg otc, Chang virus that attacks the heart buy cheap roxithromycin 150 mg on-line, and Mathes168 found that pound flaps based on their vascularization treatment for uti and yeast infection order roxithromycin toronto. Hallock ‘s pound flaps of mixed vascularization are further classification places these complex flaps into two subdivided into Siamese flaps bacteria bugs purchase discount roxithromycin on-line, conjoint flaps, and groups, those with solitary vascularization and those sequential flaps (Fig 26). The com the concept of flap prefabrication (or, more pound flap with solitary vascularization is a com accurately, prelamination178) was introduced clini posite flap that incorporates multiple tissue compo cally by Orticochea179 and Washio180 in 1971. Homma et al186 concluded that expanded muscle vascularized prefabricated flaps have larger areas of survival than expanded fascia-vascularized flaps. Maitz187 observed increased survival of delayed pre fabricated flaps, while Komuro et al188 note no sig nificant difference in survival of prefabricated arte rialized venous flaps compared with controls. Other authors suggest that because neovascularization is necessary for a successful flap, a delay of at least 4 weeks189 and even up to 8 weeks190 should be observed. Compound flaps may be subdivided into either solitary or combined types based on their source of vascularization. Com Regulation of Blood Flow to the Skin bined with skin expansion and a delay procedure, Flap physiology begins at the level of the micro prefabricated flaps are even more versatile. The microcirculation is also where ther Khouri, Upton, and Shaw182 review the principles moregulation of blood flow—the skin’s primary of flap prefabrication and list specific advantages to function—occurs. A number of factors contribute their use, including “vascular induction” of specific to the regulation of blood flow, such as distention, blocks of tissue which are not naturally perfused by endothelium-mediated vasoconstriction, neural con anatomically well-defined axial vessels—ie, 1 trol, temperature, local injury, and viscosity. The authors describe “pre ways: transfer grafting”, which was used by Barton183 to • Neural regulation acts through sympathetic incorporate skin and cartilage in a forehead flap for adrenergic fibers. Others have used it to create induce vasoconstriction and beta-adrenergic a flap incorporating a prefabricated vascularized 184 receptors induce vasodilation. Serotonin, thromboxane A2, expander in the supraclavicular region, which sub and prostaglandin F2-alpha may also produce sequently produced a capsulofasciocutaneous flap vasoconstriction, while bradykinin, histamine, after expansion was completed. Although this flap and prostaglandin-E1 cause direct vasodilation is not intended to replace the forehead for specific (Fig 27). These factors are not as signifi cant in the skin as in muscle, which has higher metabolic requirements. Local hypothermia (which acts directly on the smooth muscle in vessel walls) and increased blood viscosity (hematocrit >45%) may also decrease flow. The effects of hematocrit were questioned by Kim et al, 192 who concluded that normovolemic anemia (hct 19%) had no signifi Fig 27. With regard to systemic control, although muscle has a much higher capil the effects of local injury to a part of the arterial lary density than skin, arteriovenous shunts are wall can completely override basal vascular tone absent. And because the metabolic demand of and cause spasm even in the absence of sympa muscle is greater than that of the skin, autoregula thetic innervation. Neuronal controls a persistent isolated ring contraction locally, and such as exercise and arterial hypotension induce a extensive crushing or tearing can induce a wide reflexive vasoconstriction, while hypertension results spread and prolonged spasm distantly (Fig 28). Humoral regulation is similar except that epinepherine causes vasodilation, in direct con trast to the vasoconstriction seen in skin. In the scheme of local control, metabolic autoregulation is limited in muscle but does exceed that of skin, and blood flow is minimally changed in response to tem perature fluctuations. Burnstock and Ralevic193 review new insights into the local regulation of blood flow. The authors discuss the concept of co-transmission, whereby nerves synthesize, store, and release more than one transmitter, and the importance of the endo thelium as a mediator of vasodilation and constric tion. In summary, the mechanisms of blood flow regu lation are different in skin and muscle. Edinburgh, Churchill Livingstone, vasoconstrictors are the predominant means of regu 1994. Primary changes Most investigators endorse the concept of venous include the loss of sympathetic innervation and the insufficiency as the primary cause of necrosis in insult of ischemia. In contrast, Kerrigan found ment in pulse amplitude; little or no improvement inadequate arterial inflow was the primary cause of in circulation during the initial 48 hours; increase 198 flap failure, and proposed a combination of is in number and caliber of longitudinal anastomoses; chemia, inflammation, and sympathectomy to ex increase in the number of small vessels in the pedicle plain the vascular collapse that underlies the failing skin flap. They noted consistent edema nificant at 5 to 7 days; increase in size and number and swelling of the vascular parenchymal cells when of functioning vessels; reorientation of vessels along free flaps were subjected to a period of ischemia. Between 4 and 8 hours of ischemia, the typical 7–14 days: no further significant increase in vas cularization; arterial pattern becomes normal; ra hemodynamic and cellular events occurring in flaps dioisotope clearance indicates circulatory efficiency as a response to ischemia were reversible. As the surpassing normal values at 10–21 days, returning period of ischemia lengthened, the circulatory al to normal after 3 weeks terations gradually worsened and vascular obstruc tion progressed until they became irreversible; this 2 weeks: progressive regression of the vascular occurs after 12 hours. The point at which it is not system; continuous maturation of anastomoses be possible to reestablish nutrient inflow despite tween pedicled flap and recipient site reperfusion is known as the no-reflow phenom enon. The no-reflow phenomenon is the result of 3 weeks: vascular pattern approximates preopera ischemia-induced reperfusion injury and precedes tive state; flap achieves 90% of its final circulation; flap death. With inadequate tissue oxy pedicle and recipient site genation there is a change from aerobic to anaero bic metabolism, resulting in higher levels of super 4 weeks: all vessels decreased in diameter, few oxide radicals. The metabolic derangements of pharmacotherapeutic agents in microvascular sur tissue ischemia also affect physical properties of gery. Im et al201 in 1985 and later Manson and col Delay is the surgical interruption of a portion of leagues202, 203 noted increased production of toxic the blood supply to a flap at a preliminary stage superoxide radicals during anaerobic metabolism. The process by which delay reperfusion, the free radicals are attacked by free contributes to flap survival is likely to be a combina radical scavengers, causing further injury to the cells. Definitive investigations into flap response to sition from normal reperfusion and reperfusion injury decreased blood supply have been hampered by differs according to tissue type. Biochemical changes occurring during • vascular reorganization ischemia “actually prime the tissue to respond in a • reactive hyperemia pathological fashion upon exposure to re-established vascular supply. These reactive oxygen intermediates tions into the delay of flaps began during the 1950s. In addition, neu blood flow, together with an increase in size of the trophils contribute to the acute imflammatory injury vessels in the dermovenous plexus.

Rerouting of blood flow by tomy was the mechanism of delay, and its effect injury, inflammation, and angiogenesis caused by was to enhance vascularity. Others217, 218 confirm layed and nondelayed skin flaps to judge the effects these findings and suggest that an ischemic tissue of sympathetic denervation on the delay phenom gradient provides the impetus for angiogenesis and enon. Norepinephrine causes vasoconstriction and leads to greater viability of delayed flaps. When flaps are delayed, the angiogenic process in acute and delayed blood vessels and adrenergic nerves are severed, 219 flaps was investigated by Lopez et al by means of causing a spontaneous discharge of neurotransmit immunohistochemical methods with monoclonal ters, so that by the time of flap inset there is little antibodies to evaluate vascular endothelium.

Timing of Flap Division Much of the experimental and clinical data regarding appropriate timing of flap division is based on observations of tubed pedicle flaps, at least some of which may not have required an initial delay Fig 29.

The older term prostatodynia is also sometimes used to describe this painful prostate condition. Unlike acute or chronic bacterial prostatitis, it is not caused by any identifiable infection and therefore does not respond to treatment with antibiotics. While its cause is unknown, one theory that has been suggested is that it could be of autoimmune origin. Sometimes it is a question of being temporarily “down” or “moody” or “sad” or unable to cope, but sometimes it is more serious and needs treatment and professional counselling. Some patients may not actually realize that they are suffering from depression and this may partly be due to confusing usage of the word “depression”. People so often say that something that has occurred has made them “so depressed”, when in fact they mean that they are upset or sad or shocked about a specific incident. Under normal circumstances, patients will adjust to the situation and soon recover. There may be multiple effects: weight can go up or down, patients may sleep too much or too little, may feel tired all the time and have no energy, have feelings of guilt, feel worthless, experience confusion or forgetfulness (cognitive International Painful Bladder Foundation 2019 49 impairment), have suicidal thoughts. Depression can make it impossible to work, study and cope with or enjoy everyday life. While depression may be caused by psychiatric disorders, it may also form part of a syndrome of symptoms in chronic diseases, as has been documented in systemic lupus erythematosus, and may potentially occur in any disease with a neurological component including pain syndromes. This may be caused by an illness, by hormone imbalance, even by certain medications. Above all, patients should not be afraid or feel guilty about admitting to their doctor that they are suffering from depression. Further reading: the National Institutes of health have a useful booklet on depression online. Wikipedia also has a useful article on Depression – differential diagnoses en. It may be tiredness resulting from lack of sleep due to nightly excursions to the bathroom and to the inability to relax due to constant pain. However, intense fatigue with memory and concentration problems, known by patients as ‘brain fog’, or extreme fatigue after very little physical exertion may indicate an autoimmune disease. Fatigue on waking in the morning that improves as the day goes on may be an indication of depression. However, in practice the terms chronic fatigue and chronic fatigue syndrome are often used synonymously. Current theory concerning the cause focuses on the theory of central sensitization. As the disease progresses, the ligaments are damaged, there is erosion of the bone, resulting in deformity of the joints. This deformity of the joints is an important difference with other rheumatic diseases such as Sjogren’s syndrome. For further information about the digestive system and how it works, go to. It is advisable to keep the skin well moisturized with cream or lotion for sensitive skin to reduce the dryness and this may also reduce some of the itchiness. If possible, they should wash their clothes with products specially made for sensitive skin that do not contain perfume, wear cotton underwear and loose clothes, avoid touching garden plants that may cause skin reactions and take care in the sun if they find that their skin is sensitive to sunshine. Sjogren’s syndrome is a chronic, autoimmune disease of unknown cause in which lachrymal (tear) and salivary glands malfunction. Its hallmark symptoms are sore, irritated eyes and dry mouth with a need to drink when eating because dry food otherwise sticks to the mouth and cannot be chewed or swallowed properly (so-called “cracker sign”). It is a systemic or “generalised” disease and may therefore affect many organs and systems of the body. While some patients may experience only mild symptoms, in others their quality of life is seriously impaired by debilitating symptoms and extreme fatigue. The term Sicca Syndrome or Sicca Complex is often used for dryness of the exocrine glands, particularly the eyes and mouth when there is no evidence of autoimmune disease present. It may involve joints, skin, kidneys, lungs, heart, vascular system, gastrointestinal tract, central or peripheral nervous system and the bladder. It has the form of a butterfly with the two wings represented by the right and left lobes that wrap around the trachea. The function of the thyroid gland is to make thyroid hormone which regulates the body’s metabolism and is essential for mental and physical development. The thyroid gland is prone to two extremes of disorders: Hyperthyroidism (it makes too much hormone Hypothyroidism (it makes too little hormone). Chronic thyroiditis is an inflammatory condition of the thyroid caused by an autoimmune disorder in which lymphocytes invade the tissues of the gland. It includes swelling of the thyroid gland and partial or complete failure to secrete thyroid hormones. Vulvodynia (or vulvar pain) is a distressing, painful condition, difficult to diagnose and difficult to treat. It is a broad collective term used to describe any chronic pain condition of the vulvar area (more than three to six months) and embraces a number of different types of vulvar disorder causing chronic or intermittent pain, burning, rawness and pain with intercourse. Pain is caused by sexual intercourse, insertion of tampons, riding a bicycle, gynaecological examination, tight clothes or any situation where the vestibule is touched. It is not dependent International Painful Bladder Foundation 2019 52 upon touch or pressure but this can nevertheless exacerbate the symptoms. Generalized unprovoked vulvodynia is diagnosed when there is a history of relatively constant pain – although there may be periods of symptom relief with no visible cause or other identifiable disorder such as infection. It can cause physical incapacity, brain fog, inability to communicate to people around you, and an overwhelming sense of isolation. While fatigue is still frequently ignored, misunderstood, dismissed as psychosomatic or simply considered unimportant by many of the medical profession, it is also equally misunderstood by the patient’s family and friends. This can create a very unsympathetic environment for a patient suffering from fatigue and make it so much more difficult to cope with the condition. Fatigue may on the one hand be temporary, the cause easily diagnosable and treatable, or it may be persistent, unexplainable and fail to respond to any treatment. A patient may have only physical fatigue, or a combination of physical and mental fatigue (known as brain fog). One of the aspects that make fatigue so complex is that persistent tiredness or chronic fatigue can have multiple causes and any individual patient may be suffering from more than one cause of fatigue at the same time and therefore all of these will need to be addressed. And it is certainly not always easy to see what the cause or different causes may be, especially as the symptoms from different types of fatigue may be similar and overlap. But even only 2 or 3 times a night on a regular basis can cause considerable tiredness because some people find it very difficult to get off to sleep again once they’ve got out of bed. International Painful Bladder Foundation 2019 55 Patients may be woken up by noise: from a snoring partner, crying babies, noisy traffic etc. Therefore, each patient should carefully think about whether it is purely the bladder pain and need to void that is waking them (or keeping them awake), or whether something else has disturbed their sleep and they then feel their bladder discomfort and get out of bed. Physical and psychological impact of lack of sleep “Frequent nocturnal awakenings, particularly during the first part of the night, decrease the restorative function of sleep and can cause daytime sleepiness and impaired cognitive function. You need sleep for recuperation and restoration of physical and mental functioning. Without this proper sleep, a person deteriorates both physically and psychologically. The physical and psychological impact of sleep disruption is quite extensive and can have serious consequences as you can see from the list below: Fatigue and lack of energy Mood swings, irritability, tearfulness Lack of motivation Decreased concentration Memory lapses Motor performance impairment Disorientation Depression (adapted from Marschall-Kehrel D. The further you have to walk to reach the bathroom, the more time your body has to completely wake up, and the less likely you are to get off to sleep again when you’re back in bed. But make up for this by drinking plenty earlier in the day to avoid concentration of urine. But preferably change your medication to something that does not irritate the bladder. International Painful Bladder Foundation 2019 56 If you can’t do anything about disturbing light, wear an eye-mask. Medication causing daytime drowsiness While some medication can cause insomnia, other drugs can cause drowsiness all day long.

Human bites deemed not safe for primary closure may be packed open with frequent dressing changes and application of topical antimicrobi als antibiotics for urinary tract infection in cats roxithromycin 150 mg lowest price, then closed in a delayed fashion 2–4 days after wounding (if clean) or left to infection without antibiotics purchase roxithromycin on line heal by second intention antibiotics bronchitis purchase cheap roxithromycin. Broad-Spectrum Antibiotics A polymicrobial population antibiotic xidox discount 150mg roxithromycin otc, including anaerobic and aerobic organisms, contaminates most human bites. Thus, it is common to utilize broad spectrum antibiotics with excellent anaerobic and microaerophilic efcacy. Eliciting a history of other communi cable diseases in both patient and attacker is also prudent. Scar Revision Recipients of human bites should be made aware of probable less than ideal wound healing, and probable need for scar revision. Intravenous Bolus of a Second-Generation Cephalosporin An intravenous bolus of a second-generation cephalosporin (cefurox ime, cefoxitin) should be administered for all penetrating soft tissue bite wounds. If penicillin sensitivity cross-reaction is a major concern with a cephalosporin, then parenteral ciprofoxacin is a good choice. Parenteral Antibiotic Therapy If wounds are severe, consider continued parenteral antibiotic therapy, either as inpatient treatment or home intravenous therapy. Adhesive Dressings Bite wounds should not be concealed by adhesive dressings, as it is important to observe the wound for infection and allow slight laxity of the wound margins for seepage of serous fuid. Burn injuries tend to propagate beyond the focus of the insult, and damage may escalate for some time after the traumatic event. Keep in mind that swelling and subsequent airway compromise may present in a delayed fashion. Therefore, do not remove, or repair, tissue acutely until all wound margins have declared themselves in the days following the injury (Figure 9. Facial Subsites Many facial subsites, including the external auditory canal, eyelids, nares, and mouth, are at great risk for retraction, contraction, and stenosis. Defnitive management cannot begin until tissue viability has been declared, and may require skin grafting, local soft tissue rear rangements, stents, or other adjunctive procedures and devices. Sufered third-degree burn with vaporization of central lower lip tissues and frst-degree burns to upper lip, gingiva, and anterior tongue. Conclusion the proper initial and subsequent management of soft tissue trauma to the face, head, and neck can have far-reaching consequences for the appearance, function, and quality of life of the injured individual. Because of the importance of this region of the body, especially the face, in our daily lives, it is a prima facie responsibility of the otolaryngologist–head and neck surgeon to perform the most meticulous reconstruction of these injuries. Proper attention to careful and gentle tissue handling, minimal debridement of important facial tissue, repair of neurovascular and ductal structures, and reduction of infection and scarring will all beneft the patient’s ultimate result. This is particularly true in children, where the stigmata of facial abnormalities will be borne by them during the formative development of their self-esteem. Most soft tissue injuries to the face, head, and neck will require second ary interventions to produce the best result, and the patient and/or patient’s family should be apprised of this likelihood early in the acute management phase, followed by the development of a comprehensive plan for reconstruction that will inform them of the potential outcome, including residual sequelae and possible disabilities. The surgeon must relate to the patient and family in a caring and honest manner, develop ing the important relationship that should last through the possibility of years of secondary reconstructive procedures. Following the funda mentals presented in this chapter, and seeking additional information from other educational and clinical sources, the resident physician in otolaryngology–head and neck surgery will be well prepared to care for a wide range of traumatic injuries to the face, head, and neck. Mupirocin cream is as efective as oral cephalexin in the treatment of secondarily infected wounds. Rapid recognition, work-up, and treatment reduce the risk of complications and associated morbidity and mortality. Given the importance of endoscopy in these patients, a general understanding of the upper aerodigestive anatomy is critical in their management. Right Main Bronchus the right main bronchus is shorter, wider, and more vertical than the left. It divides into three lobar bronchi and 10 segmental bronchi: three in the superior lobe, two in the middle lobe, and fve in the inferior lobe. Left Main Bronchus the left main bronchus divides into two lobar bronchi and eight seg mental bronchi: four in the superior lobe and four in the inferior lobe. It is divided into the pyriform sinuses, the postcricoid region, and the posterior pharyn geal wall. Esophagus In adults the esophagus starts at the level of the cricopharyngeus or the upper esophageal sphincter, and ends at the lower esophageal sphinc ter. It is approximately 22 centimeters (cm) long and has three points of anatomic constriction: (1) the cricopharyngeal sphincter (16 cm from incisors), (2) the left main stem bronchus (27 cm from the incisiors), and (3) the gastroesophageal junction (38 cm from the incisors). The cricopharyngeal sphincter is the narrowest point and is at highest risk of injury or perforation. The cardiac notch is the acute angle between the intra-abdominal esopha gus and the gastric fundus. Foreign Bodies Although the incidence of aerodigestive foreign bodies has remained stable, its recognition and safety in removal have increased dramati cally. A higher incidence is found in children due to lack of molars, less con trolled coordination of swallowing, immaturity in laryngeal elevation and glottic closure, and their tendency to explore their environment by putting things in their mouth. Initial evaluation should include assessing the patient for level of alertness, respiratory distress, and hemodynamic stability. If complete obstruction is suspected the Heimlich maneuver may be attempted in an alert patient. Back blows and/or abdominal thrusts should be avoided in coughing/ gagging patients, since they may turn a partially obstructed airway into a completely obstructed airway. Finger sweeps should never be attempted, since they could push the object further into the airway. Adults often give a history of choking or dysphagia/odynophagia following a certain event. Pediatric patients are much more challenging, because only a small percentage will have a witnessed episode. A foreign body should be suspected when a patient has choking or severe coughing with respiratory distress. They should be considered in healthy children with a new onset of wheezing or patients with recurrent asthma or pneumonia. Symptoms may include: y Fever, chest pain, tachycardia, lethargy, and irritability in children. Foreign Body It is important to gather information about the foreign body: y Size. Recurrent episodes suggest the need for further work-up to rule out an underlying neuro logic or anatomic abnormality. Fiberoptic Exam In all patients, airway stability is the most important consideration. Lack of patient cooperation or intolerance of a fberoptic exam may dislodge a foreign body in the upper aerodigestive tract and lead to aspiration with subsequent obstruction. If fberoptic evaluation has the potential to turn a stable airway into an unstable airway, imaging and possible intraoperative evaluation should be considered. In pediatric patients, 70–80 percent of airway foreign bodies are vegetable matter, most commonly a radiolucent peanut. The majority of pediatric esophageal foreign bodies are radiopaque coins, but most adolescent and adult esophageal foreign bodies are food boluses. Therefore, lack of radiographic fndings does not rule out a potential foreign body in the setting of a convincing history and physical exam. In pediatric patients, failure of the dependent lung to collapse in lateral decubitus flms suggests bronchial obstruction. Decreased diaphragmatic movement on the obstructed side is noted in about 50 percent of cases. Biplanar fuoroscopy may be used for retrieval of radiopaque foreign bodies in the lung periphery. If a radiopaque foreign body is found in the alimentary tract, three factors predict spontaneous passage: y Male gender. An observation period of 8–16 hours is considered appropriate manage ment in otherwise healthy children with coin ingestion that is causing no obvious symptoms and no distressing signs. Barium Contrast Barium contrast for suspected radiolucent foreign bodies should be avoided. A negative scan is not sufcient to rule out a foreign body, as the object may be obscured by the swallowed material. Barium contrast would also delay the time for the patient to enter the operating room for endoscopy. Special Considerations Although some esophageal foreign bodies may be monitored for possible passage, some foreign bodies require emergency removal. Disk Battery If a disk battery becomes lodged in the esophagus, immediate action is required.
