Abdominal somatic receptors respond to irritation from inﬂammatory mediators and physical insults such as cutting purchase 50 mg fertomid, pinching 50 mg fertomid with amex, or burning order 50mg fertomid visa. The pain usually is sharp purchase fertomid 50mg without prescription, severe, and continuous and is aggravated by pressure, motion, and displacement. Patients suffering somatic pain lie very still, suppress urges to cough or sneeze, and resist being moved or touched in the painful area. Not infrequently, the acute abdomen begins with poorly localized visceral pain caused by swelling, distention, or ischemia of the abdominal viscus primarily involved. The pain initially is perceived in the topographic area of the abdomen corresponding to the level of 21. Subsequent irritation of the parietal peritoneum adjacent to this organ, as the inﬂammatory process progresses, pro- duces localized pain and tenderness at the exact location of the process. Diagnosing Abdominal Pain Diagnosis of the cause of abdominal pain begins with the collection of all relevant clinical information by history taking, physical examina- tion, and standard diagnostic tests. Integration of this information allows the physician to reach a preliminary or working diagnosis that may be sufﬁcient for initiating a therapeutic plan or may require further reﬁnement by way of special tests and examinations. The history of the present illness includes a careful characteriza- tion of the pain, signiﬁcant associated symptoms, and a past history of medical and surgical events that may be pertinent to the current problem. Because pain syndromes often change over time, the tempo- ral pattern is important. What potentially signiﬁcant events had occurred in the day or hours prior to the onset, and is there anything that makes the pain better or worse? Has the patient had pain like this before, and, if so, how long did it last and what was the ﬁnal outcome? Dull, constant, pressure-like pain often is indicative of an overdistended viscus; colicky pain often is indicative of hyperperistaltic muscular activity; burning and lancinating pain often is neurogenic in origin; and aching or throbbing pain suggests an inﬂammatory process under pressure. The severity of the pain, described on a scale of 1 to 10, often reﬂects the seriousness of the underlying process. Pain that is getting better usually means an improvement in the underlying pathology; however, rupture of an abscess or viscus under tension may result in a transient improvement in pain followed by more severe somatic pain. The location of the pain, both at its onset and during the examina- tion, helps in determining the site of the pathology. Is the pain local- ized, with a point of maximum intensity, or is it diffuse and ill deﬁned? Or, in the worst-case scenario, is the pain constant throughout the abdomen with attendant generalized muscular rigidity? Right upper quadrant pain that radiates to the right subscapular area is characteristic of gallbladder disease. Retroperitoneal sources like ureteral colic frequently radiate to the groin and external genital area, while subphrenic irritation often is perceived simultaneously in the upper abdomen and at the root of the ipsilateral neck. Patients with iliopsoas muscle irritation want to keep their hip ﬂexed, while patients with pancreatitis sit, leaning forward, and avoid the supine position. Those with generalized peritonitis lie very still in the supine or fetal position, while those with colicky pain move about seeking a position of comfort to no avail. Wise Associated Symptoms Associated symptoms can be useful in assessing the seriousness of the presenting pain syndrome and often help identify the organ system involved. Hemodynamic instability (shock) is a sign of a life-threatening dis- order that requires an urgent diagnostic and therapeutic response. Shock accompanying severe abdominal pain usually is hemorrhagic or hypovolemic, septic, or multifactorial. These patients often are pale, cold, prostrated, and demonstrate global neurologic impairment with confusion, disorientation, or coma. A coexistent, systemic inﬂammatory response characterized by high fever and chills, warm ﬂushed skin, and a hyperdynamic cardiovascu- lar response indicates a serious septic process and implies an underly- ing infectious or necrotizing process. Organ-speciﬁc symptoms help identify primary or secondary involvement of that system. Dyspnea, tachypnea, and hypochondral pain may be due to basilar pneumonia or cardiac infarction referred to the abdomen, or, conversely, severe pancreatitis may produce adult res- piratory distress syndrome or cardiac dysfunction. Uterine or adnexal disease and pregnancy may produce menstrual irregularities, dysmenorrhea, or vaginal discharge. In males, urethral discharge or associated prostatic or scrotal tenderness points to a gen- itourinary source. Splenic and other hematologic disorders as a cause of abdominal pain may be reﬂected in a history of easy bruisability, petechia, or prolonged and excessive bleeding. Other clues may be found in the hemogram, in the form of thrombocyte, erythrocyte, and leukocyte abnormalities. Past Medical and Surgical History A relevant past and a current medical history is essential not only for uncovering potential causes for the pain but also for assessing comor- bidity. If the current disorder has been going on for some time, previ- ous medical consultations, diagnostic tests, and procedures require review. Itemization of current medications and other treatments helps in rec- ognizing previously diagnosed disorders and in inﬂuencing further clinical management. Some medications, such as analgesics, antibiotics, chemotherapeutic agents, and corticosteroids, may be playing a role in the cause of the pain. Abdominal Pain 383 other invasive procedures may be contributing directly to the current pain syndrome or may provide other useful diagnostic information. Allergies and other adverse reactions to previous therapeutic inter- ventions must be identiﬁed to prevent repetition of misadventures in the course of diagnosis and treatment of the current illness. Notable are reactions to antibiotics and intravenous radiographic contrast materi- als. Food-based sensitivities such as gluten sensitivity in patients with celiac disease or milk intolerance in the face of lactase deﬁciency rarely may explain pain based on maldigestion. Physical Examination The physical examination provides critical information for reaching a diagnosis and is a simple, low-cost opportunity to assess important ﬁndings repeatedly over time. Changing signs are characteristic of certain clinical scenarios and help in ascertaining whether the patient is improving, stabilized, or getting worse. Extremely ill indi- viduals often can be identiﬁed by their appearance and behavior. These ﬁndings, coupled with the vital signs (pulse, blood pressure, respirations, and temperature), provide immediate clues to the patient’s hemodynamic status and whether or not there is a systemic inﬂammatory response syndrome. It is self-evident that careful examination of the abdomen is of para- mount importance but attention also must be paid to the chest, groin, external genitalia, rectal, and pelvic areas. Observation of the anterior abdominal wall should assess distention, asymmetry, focal protrusions, scars, and other signiﬁcant skin lesions. Auscultation of the abdomen is performed primarily to character- ize bowel sounds.
Relevant modifiers of evidence included severity generic fertomid 50 mg otc, duration cheap fertomid 50mg free shipping, and the presence of concurrent factors such as trauma fertomid 50 mg low price, infection buy cheap fertomid 50mg line, and other confounding diseases (e. In addition, concurrence of parameters or change in parameters over time was given greater weight (e. In making the determination of relationship to study drug, multiple factors were considered. The 3 major considerations were any pre-existing conditions, conditions with clear alternative etiology (i. Generally, conditions that began more than 1 year after the administration of study drug were not considered related to study drug. For this analysis, all classification categories of drug relatedness were combined. It should be noted that arthritis was summarized in a descriptive fashion with other adverse events. Additionally, due to coding conventions, decreased range of motion and movement in the hip coded to movement disorder, therefore, all events of movement disorder (08020760) were also reviewed. Due to coding conventions, ankle and hand swelling are coded to peripheral edema (02030425), so these events were added for review. Selected accidental injuries (01030015) were reviewed if they related to joints or the extremities. Clinical Reviewer’s Comment: At the end of the study, 116 patients were identified using the arthropathy algorithm. Four patients were removed due to changes or clarifications in the data, which modified the adverse events such that they no longer fit the definition of arthropathy). An additional 21 patients were identified by the applicant, who were not already identified by the algorithm. Of the 689 patients, 337 were in the ciprofloxacin group, and 352 were in the comparator group. As shown, 58 ciprofloxacin and 56 comparator patients did not complete study drug as planned. The most common reason for discontinuation was protocol violation (9% in each group). The majority of these protocol violations were absence of a causative organism (negative culture or no urine culture obtained), insufficient colony counts, and organisms resistant to study drugs. There were more ciprofloxacin patients (10) than comparator patients (5) who discontinued therapy due to adverse event. The two treatments groups had very similar rates of discontinuation due to the other reasons. Overall, 307 (92%) of ciprofloxacin patients and 314 (90%) of comparator patients completed 1-year post-treatment follow-up. For 5 patients (2 ciprofloxacin, 3 comparator), it could not be confirmed that any study medication was taken. There were 82 patients who were valid for safety, but not efficacy between the two arms. The clinical significance of these findings is difficult to pinpoint, but may have to do with investigators not adequately screening patients prior to enrollment or following the protocol. The potential for patient unblinding was relevant since study drug was dispensed in commercial packages and since the study drugs have different tastes and textures and different solutions (oil-based for ciprofloxacin, water-based for the comparator). At the request of the Division, an item was added to the Caregiver Questionnaire as to whether the patient/caregiver believed they knew which study drug that they received. Overall, 29 ciprofloxacin patients and 19 comparator patients answered “yes” to this question. Overall, 17 ciprofloxacin patients and 11 comparator patients answered the follow-up question. Of those patients, 10 (59%) ciprofloxacin patients and 6 (55%) comparator patients correctly identified study drug. Clinical Reviewer’s Comment: Although unblinding was a potential problem, very few patients thought they knew which study drug they received and only about half of them correctly identified study drug. Therefore, patient unblinding is not considered by the reviewer to have significantly affected the study. Valid for Safety (Intent to Treat population): Two patients in the ciprofloxacin group and 3 patients in the comparator group were randomized but it could not be confirmed by the applicant that they received study medication. Therefore, there were 335 patients in the ciprofloxacin group and 349 patients in the comparator group valid for the analysis of safety. Therefore, the valid for efficacy population included 442 patients total, 211 in the ciprofloxacin group and 231 in the comparator group. Protocol violations (28 in the ciprofloxacin group and 25 in the comparator group) included the following: • Clinical symptoms assessed outside (either too early or too late) of the Test-of-Cure visit window (Day +5 to +9) (24 ciprofloxacin group versus 21 comparator group) • Test-of-Cure visit was actually performed during the study drug administration period (3 ciprofloxacin group versus 2 comparator group) • Elevations in liver enzyme test pre-therapy (1 each in the ciprofloxacin group and the comparator group) • Pre-therapy urine culture was not obtained (1 patient in the comparator group) The following patients were inclusion/exclusion criteria violations, but the applicant allowed them to remain in the study and analysis populations: Five patients were enrolled despite the fact they were non-ambulatory at baseline. Additionally, 1 ciprofloxacin patient (301-100) had a severe baseline gait abnormality (later diagnosed as Duchenne’s disease). Patients with known underlying rheumatological disease, joint problems secondary to trauma or pre-existing conditions known to be associated with arthropathy were to be excluded from the study. Overall, 27 (8%) ciprofloxacin patients and 26 (7%) comparator patients had a medical history of any abnormal musculoskeletal or connective tissue finding. At study entry, 28 ciprofloxacin patients and 12 comparator patients had an abnormal gait assessment at baseline and 10 ciprofloxacin patients and 7 comparator patients had an abnormal joint appearance at baseline. These baseline abnormalities and medical histories may have rendered it difficult to assess any potential drug effect on gait or joint appearance. As per the caregiver questionnaires, 8 patients (3 ciprofloxacin [16001, 401074, 701034], 5 comparators [103015, 204035, 307008, 705010, 705017]) had a baseline history of seizures. These patients should have been excluded as they could have been placed at risk for seizures during therapy. Additionally, Patient 307-008 was receiving phenytoin concomitantly with study drug. Clinical Reviewer’s Comment: These baseline abnormalities make an assessment of the potential adverse effects of the drug on the musculoskeletal and neurologic systems difficult. However, given the small numbers and the roughly equal distribution across the two treatment groups, the overall impact on the interpretation of safety is minimal. Therefore, these patients will remain in the reviewer’s valid for efficacy population and will be noted for patients assessed to have arthropathy. The majority of patients enrolled are female (85% in the ciprofloxacin arm and 86% in the comparator arm). Of note, three race groups contributed the vast majority of patients: Caucasian, Hispanic and “uncodable. None of the differences between treatment groups was determined to be statistically significant, and in general the distribution of demographic variables was similar in the two groups, although there were more patients in the ciprofloxacin group than in the comparator group with severe infections (7% versus 3%). For more complete information on the enrollment of patients by age group, see Table 11. None of the differences between treatment groups was determined to be statistically significant, and in general the distribution of demographic variables was similar in the two groups, although there were more patients in the ciprofloxacin group than in the comparator group with severe infections (7% versus 4%). The distribution of patients by age group in the valid for efficacy population is shown in Table 11.

Deﬁning Problems of Fluid and Electrolyte Imbalance Fluid balance and electrolyte disorders can be classiﬁed into distur- bances of (1) extracellular ﬂuid volume; (2) sodium concentration; and (3) composition (acid–base balance and other electrolytes). When confronted with an existing problem of ﬂuid or electrolyte derange- ment, it is helpful initially to analyze the issues of ﬂuid (water) and electrolyte imbalance separately. A high serum sodium (>145mEq/L) indicates a water deﬁcit, whereas low serum sodium (<135mEq/L) conﬁrms water excess. The sodium level provides no information about the body sodium content, merely the relative amounts of free water and sodium. If serum osmolarity is high, it is important to consider the inﬂuence of other osmotically active parti- cles, including glucose. Elevated glucose should be treated and will restore, at least partially, serum osmolarity. Water Excess Although water excess may coexist with either sodium excess or deﬁcit, the most common postoperative variant, hypo-osmolar hyponatremia, may develop slowly with minimal symptoms. Rapid development results in neurologic symptoms that may eventuate in convulsions and coma if not properly addressed as discussed in Case 1. Restriction of water intake often sufﬁces in that continued sensible and insensible losses will assure free water loss. Volume is low Replace volume deficit with isotonic saline or Volume is low lactated Ringer’s solution. Volume is normal Volume is increased Replace water deficit (no Consider administration more than half in first of a loop diuretic. Fluid, Electrolyte, and Acid–Base Disorders in the Surgery Patient 71 hyponatremia), a rise in serum sodium may be achieved by adminis- tration of the desired increase of sodium (in mEq/L) = 0. An uncommon but devastating complication of raising serum sodium too rapidly is central pontine demyelinating syn- drome. To prevent this complication, it is generally recommended that symptomatic patients receive one half of the calculated sodium dose (using hypertonic sodium solutions, such as 3% saline) over 8 hours to bring serum sodium into an acceptable range (120–125mEq/L), as would be appropriate in Case 1. Do not use hypotonic saline solutions until the serum sodium is in an acceptable range. The criteria for this diagnosis also include a reduced aldos- terone level with urine sodium >20mEq/L, serum< urine osmolarity, and the absence of renal failure, hypotension, or edema. It may occur from shed blood, loss of gastrointestinal ﬂuids, diarrhea, ﬁstulous drainage, or inadequate replacement of insensible losses. Similar to changes in conditions of water excess, a severe or rapidly developing deﬁcit of water may cause several symptoms (Table 4. Lab tests for serum sodium (>145mEq/L) and osmolarity (>300mOsm/L) establish the diagnosis. Water deﬁcit results from loss of hypotonic body ﬂuids without ade- quate replacement or intake of hypertonic ﬂuids without adequate sodium excretion. Patients with decreased mental status or those unable to regulate their water intake are prone to this problem. Once a diagnosis of water deﬁcit is entertained, evaluation of urine concentrations can be useful. While water deﬁcit may be associated with either sodium excess or deﬁcit (see Algorithm 4. The signs and symptoms of hyponatremia and hypernatremia can be detected clinically (Table 4. Under such circumstances, mixed volume and concentration abnormalities often occur. Conse- quently, it is important that volume status is assessed initially before any conclusion as to changes in concentration or composition is ascribed. Sodium Excess In surgical patients, this condition is caused primarily by excess sodium intake (as may occur with infusion of isotonic saline) and renal retention. Treatment of sodium excess includes eliminating or reducing sodium intake, mobilization of edema ﬂuid for renal excre- tion (such as osmotic diuretics for ﬂuid and solute diuretics for sodium), and treatment of any underlying disease that enhances sodium retention. An algorithm for assessment of ﬂuid status and acute sodium changes is shown in Algorithm 4. Sodium Deﬁcit In the surgical patient, this condition usually occurs via loss of sodium without adequate saline replacement. Several additional sources of sodium loss should be considered, including gastrointesti- nal ﬂuids and skin. Third-space losses of sodium (and water) also can be extensive after major injury or operation. The symptoms and signs of sodium deﬁcit arise from hypovolemia and reduced tissue perfu- sion. Under such circumstances, urine sodium is low (<15mEq/L) and osmolarity is increased (>450mOsm/L). If hypotension is present, this must be treated with normal saline or lactated Ringer’s 4. A mild sodium deﬁcit without symptoms may be treated over several days if the losses of sodium have been reduced. Administration of ﬂuids for water and sodium requires knowledge of the current ﬂuid and electrolyte status of the patient, understanding of the level of stress, and appreciation for actual or potential sources of ongoing ﬂuid and electrolyte losses. Having estimated the ﬂuid and sodium status of the patient, administration of appropriate volumes of water and sodium usually is done by the intravenous route. Standard solutions of known contents nearly always are used, and the prescrib- ing physician must be familiar with these basic formulas (Table 4. Abnormalities of other electrolytes (K, Ca, P, Mg: see Abnormalities of Electrolytes, below) usually require speciﬁc ﬂuid solutions or addition of these ions to standard solutions. Changes in acid–base balance also may require special alkalotic or acidotic solutions to correct these abnormalities (Tables 4. Solution 1 is made by taking 800mL of 5% D/W and adding four ampules of 50mL (200mL) of 7. Disorders of Composition By deﬁnition, composition changes include alterations in acid–base balance plus changes in concentration of potassium, calcium, magne- sium, and phosphate. Acid–Base Balance There are four major buffers in the body: proteins, hemoglobin, phos- phate, and bicarbonate. All serve to maintain the hydrogen ion con- centration within a physiologic range. Respiratory acid–base abnormalities are identiﬁed readily by determination of Paco2.
