Penetrating zone II neck injury: does dynamic computed tomographic scan contribute to the diagnostic sensitivity of physical examination for surgically significant injury? A prospective blinded study.

OBJECTIVE: The purpose of this study was to prospectively evaluate the utility of dynamic computed tomographic (CT) scanning as a diagnostic tool and adjunct to physical examination in the identification of surgically significant penetrating zone II neck injuries. METHODS: All patients older than 14 years of age who suffered penetrating zone II neck injuries were eligible for entry into the study protocol at an urban Level I trauma center. All patients that presented with signs of surgically significant injury on physical examination underwent immediate neck exploration. Patients that did not show signs of surgically significant injury were entered into the study protocol and underwent soft tissue dynamic CT scan (1/2-cm cuts, 250-mL oral contrast) of the neck after initial resuscitation. After CT scan, all patients entered into the study protocol underwent esophagography. After completion of radiologic assessment, all study protocol patients underwent surgical exploration of the neck. The patient's surgical team was blinded to results of the CT scan and esophagography before and during surgical exploration of the neck. RESULTS: During a 42-month period from May 1997 to March 2001, 42 patients were entered into the study protocol. Thirty-six (86%) of the injuries were secondary to stab wounds and the rest were caused by gunshot wounds. Surgical exploration revealed four esophageal injuries, of which two (50%) were missed by CT scan. Esophagography missed the identical esophageal injuries, as did CT scan. Both of the missed esophageal injuries were secondary to stab wounds. Seven internal jugular vein injuries were diagnosed intraoperatively, of which four (57%) were diagnosed by CT scan. During the study period, all patients with carotid artery and tracheal injuries were diagnosed by physical examination and thus underwent immediate surgical exploration without study entry. CONCLUSION: Dynamic CT scan contributes minimally to the sensitivity of physical examination in the diagnosis of surgically significant penetrating zone II neck injury. Diagnosis of esophageal injuries with dynamic CT scan appears no better than esophagography. CT scan has greater sensitivity than physical examination for the diagnosis of jugular venous injuries; however, the majority of these injuries do not require identification or surgical intervention.

Continued experience with physical examination alone for evaluation and management of penetrating zone 2 neck injuries: results of 145 cases.

PURPOSE: Our preliminary experience with physical examination alone in the evaluation of penetrating zone 2 neck injuries for vascular trauma was previously reported in 28 patients over a 2-year period (1991-1993). The purpose of the current study was to examine the results of this approach in a much larger group of patients over an 8-year period. METHODS: The medical records for all patients admitted to our level I trauma center (all of them entered into our prospective protocol) between December 1991 and April 1999 with penetrating zone 2 neck trauma were reviewed for their initial presentation and any documented vascular injury. RESULTS: A total of 145 patients made up the study group; in 30 of these patients, the penetrating trajectory also traversed zone 1 or 3. Thirty-one patients (21%) had hard signs of vascular injury (active bleeding, expanding hematoma, bruit/thrill, pulse deficit, central neurologic deficit) and were taken immediately to the operating room; 28 (90%) of these 30 patients had either major arterial or venous injuries requiring operative repair (the false-positive rate for physical examination thus being 10%). Of the 114 patients with no hard signs, 23 underwent arteriography because of proximity of the injury to the vertebral arteries or because the trajectory included another zone. Of these 23 arteriograms, three showed abnormalities, but only one required operative repair. This case had no complications relating to the initial delay. The remaining 91 patients with no hard signs were observed without imaging or surgery for a minimum of 23 hours, and none had any evidence of vascular injury during hospitalization or during the initial 2-week follow-up period (1/114; false-negative rate for physical examination, 0.9%). CONCLUSIONS: This series confirms the earlier report indicating that patients with zone 2 penetrating neck wounds can be safely and accurately evaluated by physical examination alone to confirm or exclude vascular injury. The missed-injury rate is 0.7% (1/145) with this approach, which is comparable to arteriography in accuracy but less costly and noninvasive. Long-term follow-up is needed to confirm this management option.

Detection of groin hernia with physical examination, ultrasound, and MRI compared with laparoscopic findings.

OBJECTIVE: To determine the diagnostic accuracy of physical examination, ultrasound, and dynamic MRI in patients with inguinal hernia. METHODS: In 41 patients with clinically evident herniations, 82 groins were evaluated using a standard ultrasound and MRI protocol, the latter including T1- and T2-weighted sequences as well as two dynamic sequences. All ultrasound examinations and MRI scans were reviewed without knowledge of clinical findings. In all cases, correlation with findings at laparoscopic surgery was made. RESULTS: At surgery, 55 inguinal herniations were found. Physical examination revealed 42 herniations (one false-positive finding), whereas ultrasound made the diagnosis of a hernia in 56 cases (five false-positive and four false-negative findings). MRI diagnosed 53 herniations (one false-positive and three false-negative findings). Thus, sensitivity and specificity figures were 74.5% and 96.3% for physical examination, 92.7% and 81.5% for ultrasound, and 94.5% and 96.3% for MRI. CONCLUSIONS: In patients with clinically uncertain herniations, MRI is a valid diagnostic tool with a high positive predictive value.

Interrater reliability and physical examination of the pubovisceral portion of the levator ani muscle, validity comparisons using MR imaging.

AIMS: Defects in the pubovisceral portion of the levator ani muscle are seen with MR imaging. This study aims to determine interrater reliability of physical examination in detecting these defects, and to validate findings from physical examination using comparisons with MR images. METHODS: Two examiners palpated the pubovisceral muscles of 29 women to assess for defects in this muscle. Each examiner was blinded to the others findings. MR scans were acquired on a further 24 women after structured clinical examination by one examiner. These images were read to determine pubovisceral muscle defects, blinded to patient identifiers. Agreement between raters and between MR imaging and clinical examination were calculated. RESULTS: The two examiners had positive agreement (presence of a defect) of 72.7% and negative agreement (absence of a defect) of 83.3%. The positive agreement between physical examination and MR imaging was 27.3% and the negative agreement 86.5%. CONCLUSION: The structured physical examination to detect defects in the pubovisceral portion of the levator ani muscle can be learned as shown by good interrater agreement. However, examination alone underestimates these defects compared with MR imaging.

Preparticipation physical examination using a box drop vertical jump test in young athletes: the effects of puberty and sex.

OBJECTIVE: Neuromuscular performance increases rapidly in males throughout pubertal development, whereas no similar neuromuscular spurt occurs in females. This fact may underlie neuromuscular imbalances related to increased risk of injury in females. The hypothesis: female athletes would demonstrate mismatched landing force to power production compared with males. DESIGN: This study used a cross-sectional study design to compare cohorts of pubertal stage-matched males and females during preparticipation physical examination. SETTING: An onsite preparticipation physical examination at a Texas High School. PARTICIPANTS: Two hundred seventy-five middle school and high school athletes (Tanner Stages 2 to 5) volunteered to participate (87 females, 188 males) in a preseason physical screening. MAIN OUTCOME MEASURES: Vertical ground reaction forces were used to determine the effects of sex and pubertal stage on the calculated measures. Subjects performed 3 drop vertical jumps onto a portable force platform. RESULTS: Females demonstrated no increase in vertical jump height whereas males increased on average 12.5% between pubertal stages (P=0.002). The ratios of the drop landing force to drop take-off and maximum landing force to maximum take-off force were decreased in males as they matured (P<0.05) whereas females did not change between pubertal stages. CONCLUSIONS: Preparticipation physical examination may be used to determine potential high-risk landing force profiles in young athletes before participation. Female athletes may exhibit high-risk landing profiles at all stages of pubertal development that may increase risk of injury during landing compared with males. CLINICAL RELEVANCE: Preseason intervention may be warranted for females with high-risk landing profiles identified during preparticipation physical examination.

Penetrating injuries of the neck in patients in stable condition. Physical examination, angiography, or color flow Doppler imaging.

BACKGROUND: The initial assessment of penetrating injuries of the neck is controversial, with angiography remaining the gold standard for identifying vascular injuries. Recent reports suggest that physical examination might be an accurate way to evaluate these injuries. Color flow Doppler imaging has been used with promising results to assess extremity injuries, but the role of color flow Doppler imaging in neck injuries has not been studied. OBJECTIVE: To evaluate and compare the roles of physical examination, color flow Doppler imaging, and angiography in the identification and management of penetrating neck injuries. STUDY DESIGN: A prospective study of patients in stable condition with penetrating injuries of the neck. All study patients were examined according to a written clinical protocol and subsequently underwent angiography and color flow Doppler imaging. The sensitivity and specificity of physical examination and color flow Doppler imaging were compared with those of angiography. RESULTS: Eighty-two patients fulfilled the criteria for inclusion in the study. Angiography demonstrated vascular lesions in 11 patients (13.4%), but only two (2.4%) of them required treatment. Serious injuries were detected or suspected during physical examination, but six lesions not requiring treatment were missed. When injuries not requiring treatment were excluded, the sensitivity was 100% and the specificity was 91%. With color flow Doppler imaging, 10 of the 11 injuries were identified, for a sensitivity of 91% and a specificity of 98.6%. The sensitivity and specificity were 100% for clinically important lesions. CONCLUSION: The combination of a careful physical examination and color flow Doppler imaging provides a reliable way to assess penetrating neck trauma and may be a safe alternative to routine contrast angiography.

Review of systems, physical examination, and routine tests for case-finding in ambulatory patients.

The screening value of the comprehensive review of systems and the complete physical examination in detecting unsuspected diseases for which therapeutic interventions are initiated has not been formally studied in ambulatory patients. The medical records of 100 randomly selected adult patients who had an ambulatory general medical evaluation at the Mayo Clinic in 1990-1991 were surveyed to compare review of systems and physical examination with routine laboratory tests, chest radiography, and electrocardiography as case-finding maneuvers. The main outcome measure was the therapeutic yield of each case-finding maneuver, defined as the proportion of maneuvers leading to a new therapy for a new clinically important diagnosis. The utilization rate of routine tests in the 100 patients (mean age: 59 +/- 16 years; 58% women) was high, ranging from 77 to 98%. Overall, the case-finding maneuvers led to 36 unsuspected clinically important diagnoses and resulted in 25 new therapeutic interventions. Higher therapeutic yield was observed for review of systems (7%), physical examination (5%), and lipid screening (9.2%) than for chemistry group (2.2%), complete blood count (1.8%), thyroid tests (1.5%), urinalysis (1.1%), electrocardiography (0%), or chest radiography (0%). The number of therapeutic interventions was not associated with patient's age (P = 0.55), sex (P = 0.88), comorbidity (P = 0.30) or with the time interval since the last general medical evaluation (P = 0.12). Based on therapeutic yield, these data suggest that review of systems and physical examination are valuable case-finding maneuvers in the periodic medical evaluation of ambulatory patients.

A collaborative effort to study methods of teaching physical examination skills.

A collaborative study was conducted between two medical schools to evaluate critically the teaching of physical examination skills to first-year medical students, assess the effect of different instructional methods on student performance, and improve teaching programs at both schools. Students at the two schools were videotaped performing a physical examination on a paid model at the completion of their physical diagnosis courses. The videotapes were sent to a third school for independent evaluation based on criteria agreed upon by all three schools. Students participating in a highly structured course and utilizing a very specific behavioral checklist as both a teaching and evaluating instrument tended to perform more complete physical examinations than students from a less structured course and employing a more generalized checklist. Both medical schools benefited from participation in the study.

[Clinical techniques for use in neurological physical examinations. II. Motor and reflex functions].

AIMS: The aim of this study is to highlight the chief practical aspects of the techniques used in the neurological physical examination of the motor and reflex functions. DEVELOPMENT: We recommend clinicians to carry out a brief but consistent and effective exploration in a systematic, flexible and orderly manner to check for abnormalities in the motor and reflex functions of the nervous system. Should any anomalies be detected, then a more detailed and thorough neurological exploration must be performed selectively. We present a detailed review of the practical aspects of the main techniques used in the physical examination of these neurological categories. The motor function is explored using techniques that examine muscle tone, muscle strength, muscle fatigability, hypokinesia, tremor, coordination and gait. Lastly, in this category several manoeuvres that are useful in hysterical or mimicking paralyses are also dealt with. Reflexes to examination are usually divided into: 1. Myotatic reflexes; 2. Cutaneomucous reflexes; 3. Spinal cord or defence automatism reflexes; 4. Posture and attitude reflexes. We also add the study of primitive pathological reflexes, remote reflexes, synkinesias and signs of meningeal irritation. CONCLUSIONS: We present a detailed description of the main clinical techniques used in the neurological physical examination of motility and reflexes, as well as an approach that allows them to be performed on adult patients. In addition, we underline the importance of physically examining the nervous system in contemporary medicine and the need to continually perfect the way these techniques are performed in order to achieve an efficient clinical practice.

[Atopic dermatitis and related factors observed at infant physical examination at health centers].

We investigated the incidence of atopic dermatitis and related factors at infant physical examination at health centers. Subjects were 900 infants (290 four-month-old infants, 298 one-year and six month-old infants, 312 three-year-old infants) who participated in infant physical examinations in Kanazawa-ku, Yokohama City. Overall, we analyzed 696 infants whose mothers had cooperated with the survey by completing questionnaires during physical examinations, and who submitted to examination by consulting dermatologists. The incidence of atopic dermatitis was 11.6% in 4-month-old infants, 12.2% in 1.5-year-old infants, and 12.1% in 3-year-old infants. The following were found to be related to the atopic dermatitis of infants. 1. Family history of atopic dermatitis in their mothers and older siblings. 2. Mothers' limited diet during pregnancy (avoiding some food which are suspected allergens). 3. Past history of molluscum contagiosum. 4. The frequency of taking bath. While epidemiological surveys of atopic dermatitis have previously been performed, the criteria at each survey was not identical and results could not be compared precisely. In this survey, 1. Dermatologists specializing in atopic dermatitis performed examinations. 2. All diagnoses were made according to standardized criteria which are applied nationwide. 3. All subjects were from a specific region. Because of this approach, this survey provides important information that can form the basis of comparison for future epidemiological surveys of atopic dermatitis.

The physical examination of migraine.

Patients and physicians are frequently unaware that pain coming from the muscles of the head and neck is probably the cause of the most frequent forms of migraine. Identifying the extracranial origins of the patient's headache by physical examination should reassure patient and examiner that the headache is benign and treatable. The results of the examination should lead to physical treatment, reducing headache frequency and severity. This paper describes techniques of the physical examination to identify the extracranial causes of migraine headache.

Physical examination versus normalized pressure ratio for predicting outcomes of hemodialysis access interventions.

PURPOSE: The ratio of intragraft venous limb pressure (VLP) to systemic pressure (S) has been proposed to help determine the endpoint of hemodialysis access interventions. It was hypothesized that physical examination of the access could be used in the same way and these techniques were compared as predictors of outcome. PATIENTS AND METHODS: With use of a quality-assurance database, records from 117 hemodialysis access interventions were retrospectively reviewed. Only interventions in grafts were included. The database included physical examination (to establish thrill, thrill with slight pulsatility [TSP], pulse with slight thrill [PST], and pulse) at three locations along the graft (proximal, midportion, and distal), normalized pressure ratio calculated with S from a blood pressure cuff (S(cuff)) and S within the graft with outflow occluded (S(direct)), graft configuration and location, indication, operator, and time to next intervention (outcome of primary patency). Only procedures with complete follow-up data were included in the analysis (n = 97; declotting, n = 51; prophylactic percutaneous transluminal angioplasty [PTA], n = 46). Statistical analysis was performed with use of Cox proportional-hazards regression. RESULTS: Graft configuration, location, side, VLP, S(direct), and S(cuff) did not affect outcomes. An operator effect was noted for two physicians and was adjusted for in all analyses. Pressure ratios were weak predictors of outcome (VLP/S(direct), P =.07; VLP/S(cuff), P =.08) and suggested that patency increased with increasing pressure ratio, contrary to earlier studies. Procedure type predicted outcome (declotting, median patency of 50 days; PTA, median patency of 105 days; P =.01). Thrill at distal physical examination was predictive of outcome (P =.04) and even more so when thrill and TSP combined were compared with PST and pulse combined (P =.03). Similar but less-pronounced effects were seen at midportion and proximal physical examinations. CONCLUSIONS: The presence of a thrill or slightly pulsatile thrill at the distal (venous) end of a dialysis graft is the best predictor of outcome after percutaneous intervention. Based on the present study, the authors believe that physical examination of dialysis access should supplant pressure measurements as an endpoint of intervention and should serve as an essential component of quality assurance of access interventions.

Reliability of history and physical examination findings for assessing control of glycemia in dogs with diabetes mellitus: 53 cases (1995-1998).

OBJECTIVE: To evaluate the reliability of history and physical examination findings for assessing control of glycemia in insulin-treated diabetic dogs. DESIGN: Retrospective study. ANIMALS: 53 insulin-treated dogs with diabetes mellitus. PROCEDURE: Medical records of insulin-treated diabetic dogs from June 1995 to June 1998 were reviewed, and information on owner perception of their dog's response to insulin treatment, physical examination findings, body weight, insulin dosage, and concentrations of food-withheld (i.e., fasting) blood glucose (FBG), mean blood glucose (MBG) during an 8-hour period, blood glycosylated hemoglobin (GHb), and serum fructosamine was obtained. Owner's perception of their dog's response to insulin treatment, physical examination findings, and changes in body weight were used to classify control of glycemia as good or poor for each dog. The FBG, MBG/8 h, blood GHb, and serum fructosamine concentrations were compared between well-controlled and poorly controlled insulin-treated diabetic dogs. RESULTS: Presence or absence of polyuria, polydipsia, polyphagia, lethargy, and weakness were most helpful in classifying control of glycemia. Mean FBG and MBG/8 h concentrations, blood GHb concentrations, and serum fructosamine concentrations were significantly decreased in 25 well-controlled diabetic dogs, compared with 28 poorly controlled diabetic dogs. Most well-controlled diabetic dogs had concentrations of FBG between 100 and 300 mg/dl, MBG/8 h < or = 250 mg/dl, blood GHb < or = 7.5%, and serum fructosamine < or = 525 mumol/L, whereas most poorly controlled diabetic dogs had results that were greater than these values. CONCLUSIONS AND CLINICAL RELEVANCE: Reliance on history, physical examination findings, and changes in body weight are effective for initially assessing control of glycemia in insulin-treated diabetic dogs.

History and physical examination.

In summary, the history and physical examination provide a valuable overview of a patient's condition and clues as to the causes. Typically, the most important features are evidence of gynecomastia, completeness of genital development and virilization, testicular size and consistency, and condition of the prostate gland. Preliminary laboratory evaluation is usually done at the conclusion of the initial evaluation and generally includes a total or free testosterone level, a semen analysis, urinalysis, and screening profiles for blood count, liver and renal function, and serum electrolytes. A more detailed hormonal evaluation would include gonadotropins, luteinizing hormone and follicle-stimulating hormone, prolactin, estradiol, and possibly thyroid studies. With this information complete, the astute clinician can develop a working diagnosis and plan for further evaluation or referral to a specialist.

Triple approach in the diagnosis of dominant breast masses: combined physical examination, mammography, and fine-needle aspiration.

In an attempt to reduce the number of breast biopsies done for benign breast disease in patients with breast lumps, we evaluated prospectively the sensitivity and specificity of the combination of three diagnostic modalities: clinical examination, mammography, and fine-needle aspiration cytologic examination (FNA). A total of 234 patients with a breast mass had a physical examination, a mammogram, and FNA, and were listed as malignant/suspicious or benign. All patients underwent a subsequent biopsy: 110 were found to have breast cancer, and 124 had a benign lesion. The sensitivity and specificity of the individual tests were as follows: 89% and 73%, respectively, for mammographic examination; 93% and 97% for FNA cytologic examination; and 89% and 60% for physical examination. For the combined triad of tests, the sensitivity was 100% and specificity 57%. All patients who had breast cancer had positive findings for malignancy in one or more of the diagnostic tests, i.e., 100% sensitively. All patients who had negative findings for malignancy in all three diagnostic tests had benign lesions, i.e., a negative predictive value of 100%. We conclude that breast masses can be diagnosed with a high degree of accuracy by combined physical, mammographic, and fine-needle aspiration cytologic examination. Patients in whom physical examination, mammography, and FNA were negative for malignancy can be safely observed, obviating the need for an open biopsy.

Physical examination as a reliable tool to predict intra-abdominal injuries in brain-injured children.

BACKGROUND: Brain-injured children have been thought to have an unreliable abdominal examination. This study evaluates the reliability of physical examination in the prediction of intra-abdominal injury in brain-injured children. METHODS: Pediatric patients with a traumatic brain injury or Glasgow Coma Scale (GCS) <15 and intra-abdominal organ injuries were selected. Admission data were reviewed, and findings were tabulated. RESULTS: Fifty patients had an abnormal abdominal examination. Nineteen of 71 patients with head injury and intra-abdominal organ injuries required laparotomy. These 19 patients had abdominal tenderness, distention, abrasions, and/or a positive focused abdominal sonography for trauma (FAST) scan. Seven of 19 patients had a GCS of 3. Of the 12 patients requiring surgery with GSC 4 to 14, all patients had abnormal physical examinations. CONCLUSIONS: Patients who required an operation presented with an abnormal examination and/or a positive FAST. These data suggest that examination and/or FAST may reliably identify patients with intra-abdominal organ injuries in need of an operation.
