Foreign body aspiration in children: value of radiography and complications of bronchoscopy

PURPOSE: The authors undertook a 10-year review of bronchoscopies for airway foreign bodies in children to test assertions in previous reports that (1) characteristic abnormalities in chest radiographs are important indicators of the need for bronchoscopy and (2) experienced operators incur negligible complications. METHODS: The medical records of 293 children who underwent bronchoscopies by experienced pediatric surgeons for suspected airway foreign bodies were reviewed for patient age, symptoms, duration of symptoms before bronchoscopy, prebronchoscopy radiographs, type of foreign body, anatomic location of foreign body, success of bronchoscopic removal, length of hospital stay, and complications. RESULTS: Of the 293 bronchoscopies, 265 showed airway foreign bodies. A choking episode was recorded in 228 of the 265 patients with foreign bodies and 5 of the 28 with negative bronchoscopy. The surgeon thought that radiographs were normal at the time of bronchoscopy in 110 patients who had foreign bodies. Nine patients with foreign bodies had atypical radiographs; three had bilateral emphysema and six had upper lobe or bilateral atelectasis or pneumonia. There were three complications: one vocal cord injury requiring temporary tracheostomy, one tracheal laceration from removal of an aspirated tooth, and one severe postoperative subglottic edema requiring a 4-day hospital stay. The age of the patients, symptoms, types of foreign bodies, locations of foreign bodies, management, and outcomes were similar to those of previous reports. CONCLUSIONS: In children with airway foreign bodies, chest radiograph findings are frequently normal and can display abnormalities uncharacteristic for foreign body aspiration. Children witnessed to choke while having small particles in their mouths and noted subsequently to have raspy respiration, wheezing, or coughing should undergo prompt bronchoscopy regardless of radiographic findings. Complications of bronchoscopy for foreign body aspiration are uncommon but occur even in experienced hands.     

What influences patients' reports of three aspects of hospital services?

OBJECTIVES: Market forces make it essential to know what policies and actions influence patients' reports of hospital services. No studies have examined the role of patient characteristics, labor quality and staff characteristics, nonlabor resources, managerial practices, and employee attitudes within a single investigation. METHODS: The authors collected, simultaneously, data about labor, management and service processes, nonlabor resources, and employee attitudes on 117 nonintensive medical-surgical inpatient units in 17 hospitals selected from a pool of 69 institutions within a metropolitan area by a stratified random sample. Of the 2,595 patients who agreed to participate, 2,051 (79%) completed telephone interviews regarding their experiences with physical care, education, and pain management services within 26 days of hospital discharge. RESULTS: A significant amount of variation in patients' service reports was explained (adjusted R2 = 0.41 physical care, 0.35 pain management, 0.44 education). Although the predictors varied for each service report, patient characteristics, especially those related to personal resources, had a large explanatory role. A labor assignment pattern that could explain why earlier studies found labor quality and staff characteristics to have only a weak role in the prediction of patients' service reports was noted. CONCLUSIONS: The results related to patient characteristics may indicate opportunities to improve care by confronting service design strategies that erroneously rely on a homogeneous patient population. Measurement challenges identified by this study must be addressed to determine the role of labor quantity and staff characteristics.     

Palisaded encapsulated neuroma of the nasal fossa

The aim of the study was to assess the potential application of teleradiology in the neonatal intensive care unit (NICU) by ascertaining whether any decrease in conspicuity of anatomic detail or interventional devices in the chest radiographs of premature infants is caused by picture archiving and communication system (PACS)-based soft copy interpretation of 10 : 1 compressed images. One hundred digital chest radiographs of low-birthweight infants were obtained in the NICU using a storage phosphor system. Laser-printed images were interpreted and the data set for each radiograph was then irreversibly compressed by a 10 : 1 ratio. Four radiologists with extensive PACS experience used a five-point grading system to score laser-printed hard copy images for the visibility of six parameters of anatomic landmarks and interventional devices in the chest. Compressed soft copy images displayed on 2K PACS workstation were subsequently scored using the same approach. Statistical manipulation demonstrated no loss of anatomic detail in five of the six parameters scored, with minimal difference in one landmark, the retrocardiac lung assessment. While further study is required to assess the clinical impact of the variance noted when evaluating lung parameters, the preservation or improvement of information in the remaining parameters following irreversible compression and soft copy interpretation is promising for the potential use of teleradiology in this population.     

Teleradiology in rural imaging centres

An economic analysis of a private commercial magnetic resonance (MR) imaging service was carried out. At an expected case-load of 2000 per year, a mid-field MR unit was predicted to cost $470 per case using teleradiology and $544 per case using film and a courier service. Routine and emergency MR services were provided to two communities in Maryland. In a two-year study period, 8083 teleradiology examinations were performed. Digital images were acquired and transmitted without data compression via ISDN at 128 kbit/s to a central diagnostic workstation for interpretation by a team of radiologists. The average transmission time for a typical case of 50 images was 6-8 min. Preliminary interpretations were normally available within 2 h and the final transcribed reports were usually faxed to the physicians' offices within 24 h. The results of a survey indicated that the system was well received by both referring physicians and patients. Costs per case in practice were similar to those predicted.     

Characterization of protein kinase C-mediated phosphorylation of the short cytoplasmic domain isoform of C-CAM

BACKGROUND: Picture Archiving Communication System (PACS) is a sophisticated software and hardware package that enables clinicians to retrieve, review, and digitally manipulate radiographs from computer workstations throughout the hospital. PACS was instituted at Brooke Army Medical Center in July 1993. METHODS: Fifty consecutive trauma and 50 consecutive motor vehicle crash (MVC) trauma admissions to an urban trauma center were reviewed before PACS (January 1993) and 18 months after PACS was instituted (January 1995). Patients were compared by the number of radiographs needed during the initial evaluation by type and total. The trauma groups were subdivided by mechanism and also compared. Demographic and physiologic data were collected for each patient. RESULTS: There are no differences in the demographic and physiologic data between groups. For the 50 consecutive trauma admissions, only two areas of statistical difference were found: more chest films were obtained in the MVC PACS group and more pelvis films were obtained in the gunshot wound pre-PACS group. For the 50 consecutive MVC trauma admissions, the PACS group had more chest and total radiographs per patient than the pre-PACS group. More computed tomographic scans of the neck were obtained in the PACS group. CONCLUSION: PACS did not decrease the number of radiographs needed to adequately and fully evaluate the trauma patient.     

High-resolution CT of the lung: determination of the usefulness of CT scans obtained with the patient prone based on plain radiographic findings

OBJECTIVE: We assessed the usefulness of chest radiographs for predicting whether high-resolution CT scans obtained with the patient prone would be valuable in assessing suspected diffuse lung disease. MATERIALS AND METHODS: In 100 consecutive patients undergoing high-resolution CT, findings on plain chest radiographs were classified as normal, possibly abnormal, or abnormal. CT scans obtained with the patient supine were assessed for the presence and distribution of lung abnormalities without knowledge of the plain radiographic classification. A second review of the CT scans was done with equal numbers of scans obtained with the patient prone and with the patient supine. The usefulness of the CT scans obtained with the patient prone for detecting lung disease was determined and related to the plain radiographic classifications. RESULTS: High-resolution CT scans obtained with patients prone were helpful in excluding or confirming posterior lung abnormalities in 10 (28%) of 36 patients who had normal findings on chest radiographs, five (28%) of 18 patients who had possibly abnormal findings on chest radiographs, and only two (4%) of 46 patients who had abnormal findings on chest radiographs. The proportion of patients who benefited from high-resolution CT scans obtained with the patient prone was significantly lower among the patients with abnormal findings on chest radiographs than among the patients with normal (p = .008) or possibly abnormal (p = .02) findings on chest radiographs. The two patients with abnormal findings on radiographs in whom CT scans obtained with the patient prone were helpful had minimal radiographic abnormalities. CONCLUSION: In patients with suspected diffuse lung disease, obtaining high-resolution CT scans with the patient prone may be useful when chest radiographs show normal findings, possibly abnormal findings, or minimal abnormalities indicative of diffuse lung disease. However, such scans are of little value in patients whose radiographs show abnormalities indicative of diffuse lung disease.     

Feasibility of national benchmarking of patient satisfaction with Australian hospitals

PURPOSE: This paper discusses the feasibility of developing national benchmark questions on patient satisfaction with hospital care in Australian hospitals. The research was undertaken for the Australian government under the National Health Outcomes Programme. DATA SOURCES AND SELECTION: The paper draws on a review of research with consumers to identify issues of importance to them about hospital care. The Australian sources were reports by consumer and community organizations, research reports by hospitals, governments and academics, and data from complaints authorities. The emphasis was on consumers' own views. The main debates on patient satisfaction methodology were reviewed. Published material from the USA and Britain highlighting organizational policy issues was reviewed, as well as literature on benchmarking. Material was obtained through journal searches and identification of organizations which undertake consumer-oriented or service development research. CONCLUSIONS: The paper argues that national benchmarking of patient satisfaction is not reliable because patient satisfaction is a poorly understood concept and not a unitary concept. Also, the paper argues that benchmarking is about processes, and that the link between survey results and hospital processes is not well researched or understood. While patient satisfaction surveys appear to promote consumer perspectives, they remain caught within a passive approach to consumer participation in shaping service development and improving the quality of hospital care. The task of government is to mandate consumer feedback, resource the development of expertise and technologies, trial and evaluate approaches to obtaining feedback, disseminate research and effective models, and resource consumer organizations to be participants at all stages. This is described as providing the resources for benchmarking at local levels.     

Automating and improving the data quality of a nursing department quality management program at a university hospital

BACKGROUND: The development and implementation of a relational database program for nursing quality management at a university hospital was stimulated by a lack of consistent data management and analysis tools in the existing noncomputerized program. PROGRAM DEVELOPMENT AND IMPLEMENTATION: An initial software prototype implemented in the critical care service included data collection instruments for five areas: medication errors, patient falls, returns to an intensive care unit within 48 hours, hospital-acquired skin breakdown, and unplanned extubations. Access to the database was limited and paper reports only were disseminated on a scheduled basis. In a second phase, the database is being deployed throughout the nursing department using a local area network. Nurse managers will enter and interact with the quality database online and have access to graphics, reports, and action plan development. POSSIBLE ERRORS: A wide range of potential errors influences decisions on how to collect, store, retrieve, and process quality management data. Each type of error affects the nurse manager's ability to identify significant patterns or trends that are amenable to intervention. There is no right way of constructing and implementing a quality improvement database; only an optimum balance between cost, complexity, and efficacy. SUMMARY AND CONCLUSIONS: Initial feedback from end uses has been positive. A three-year experience with a personal computer database suggests that the personal computer-based information technology is appropriate for small to medium applications and can support departmentwide CQI efforts. A case scenario using simulated data is included to illustrate the use of computerized reports in assessing and taking action on an increase in falls.     

Increased left ventricular muscle mass after long-term altitude training in athletes

STUDY OBJECTIVES: To compare the costs and effectiveness of directly observed therapy (DOT) vs self-administered therapy (SAT) for the treatment of active tuberculosis. DESIGN: Decision analysis. SETTING: We used published rates for failure of therapy, relapse, and acquired multidrug resistance during the initial treatment of drug-susceptible tuberculosis cases using DOT or SAT. We estimated costs of tuberculosis treatment at an urban tuberculosis control program, a municipal hospital, and a hospital specializing in treating drug-resistant tuberculosis. OUTCOME MEASURES: The average cost per patient to cure drug-susceptible tuberculosis, including the cost of treating failures of initial treatment. RESULTS: The direct costs of initial therapy with DOT and SAT were similar ($1,206 vs $1,221 per patient, respectively), although DOT was more expensive when patient time costs were included. When the costs of relapse and failure were included in the model, DOT was less expensive than SAT, whether considering outpatient costs only ($1,405 vs $2,314 per patient treated), outpatient plus inpatient costs ($2,785 vs $10,529 per patient treated), or outpatient, inpatient, and patients' time costs ($3,999 vs $12,167 per patient treated). Threshold analysis demonstrated that DOT was less expensive than SAT through a wide range of cost estimates and clinical event rates. CONCLUSION: Despite its greater initial cost, DOT is a more cost-effective strategy than SAT because it achieves a higher cure rate after initial therapy, and thereby decreases treatment costs associated with failure of therapy and acquired drug resistance. This cost-effectiveness analysis supports the widespread implementation of DOT.     

Routine portable chest radiographs in the medical intensive care unit: effects and costs

OBJECTIVE: To determine the effects and net costs of routine chest radiographs in a medical intensive care unit (ICU). DESIGN: A prospective, cohort study. A survey of experts in critical care and pulmonary diseases was undertaken to assess the effect of routine radiographs on patient management. SETTING: Medical ICU of a university hospital. PATIENTS: Eighty randomly selected patients admitted to a medical ICU. Two hundred fourteen experts were surveyed; 118 (55%)/214 responded. MEASUREMENTS AND MAIN RESULTS: Daily interviews with medical ICU clinicians were conducted to assess the radiographic findings in the routine radiographs and actions taken based on these findings. Experts evaluated the findings, their importance, the actions taken, and the probability of complications if the actions had not been taken at that time. Experts also predicted increases in length of stay associated with these complications. Presence of radiographic findings, changes in management because of the findings, net costs of routine chest radiographs, cost per finding that prompted an action, and expected changes in length of stay resulting from the actions were also assessed. Seventy-two (33%) of 221 routine radiographs (95% confidence interval: 25% to 39%) had findings, of which 44 (61%) were judged important, and 18 (8%, 95% confidence interval: 5% to 12%) prompted actions. Experts predicted that each action averted, on average, 2.1 +/- 1.7 days (SD) in the medical ICU. Mean savings per routine radiograph was $98. Net savings from routine chest radiographs remained after sensitivity analysis for expected change in length of stay, percentage of patients with routine radiographs, and percentage of routine radiographs that produce changes in management. CONCLUSION: The policy of obtaining routine chest radiographs in the medical ICU is effective and results in net savings.     

Zone III fractures of the sacrum. A case report

STUDY DESIGN: Case reports. OBJECTIVES: To define the radiologic characteristics, management, and results of Zone III fractures of the sacrum. SUMMARY OF BACKGROUND DATA: Zone III fractures of the sacrum are rare. There are few case reports of longitudinal fractures of the sacrum involving Zone III. METHOD: The authors report eight (four transverse, four longitudinal) Zone III fractures of the sacrum. Seven patients were treated surgically by posterior sacral decompression with or without transiliac bar fixation, and one neurologically intact patient with undisplaced longitudinal fracture was treated conservatively. RESULTS: Two neurologically compromised patients had return of normal bladder and rectal function, and another had bladder recovery only. The rest continued to show neurogenic bladder and required intermittent self-catheterization. The patient with bilateral foot drop had partial motor recovery and did not require an ankle-foot orthosis. CONCLUSIONS: These fractures may be difficult to diagnose in polytraumatized patients and require a high index of suspicion. The longitudinal fractures may not be apparent on anteroposterior radiographs, and computed tomography scan may be necessary for establishing the diagnosis. The transverse fractures may show a characteristic step ladder sign on anteroposterior radiographs when the fracture is displaced severely. Proper lateral radiographs often are difficult to obtain, particularly in obese polytraumatized patients. Routine computed tomography scan may overlook the diagnosis. Therefore 2- to 3-mm computed tomography cuts are recommended, which may show double neural foramina in presence of significant anteroposterior displacement and overriding of the fracture fragments. Sagittal computed tomography reconstructions are useful in evaluating the transverse fractures. Posterior sacral decompression is safe and probably promotes nerve root recovery. Longitudinal fractures may be stabilized satisfactorily by transiliac rod fixation.     

Changes in nasal tip projection and rotation after septorhinoplasty: a cephalometric analysis

PURPOSE: This prospective study reports on changes in nasal tip projection and nasal tip rotation before and after septorhinoplasty analyzed cephalometrically. PATIENTS AND METHODS: Forty patients undergoing primary septorhinoplasty were studied prospectively. Lateral cephalometric radiographs taken in the natural head position were obtained before and 6 to 45 months (mean, 17.1) after surgery. In 10 patients, serial radiographs were taken at 6 and 12 months, and in seven patients they were taken at 12 and 24 months after surgery. Nasal tip projection (NTP) was defined as the distance between articulare (Ar) and pronasion (PRN). Nasal tip rotation (NTR) was defined as the change in the angle (N-Ar-PRN) after surgery. A surgical goal to increase, decrease, or maintain NTP and NTR was assigned to each patient before surgery. RESULTS: NTP changed in the desired direction in 16 of 40 patients (40%). NTR changed in the desired direction in 25 of 40 patients (63%). In the patients studied serially, NTP decreased an average 0.7 mm between 6 and 12 months (P = .018), and 0.6 mm between 12 and 24 months (P = .071). CONCLUSIONS: Decreased NTP and NTR were the most easily achieved surgical objectives. Maintaining or increasing NTP is less predictable. Typically, there is a progressive loss of NTP after surgery independent of the surgical goal. Cephalometric analysis is a useful tool to measure changes in NTP and NTR after septorhinoplasty.     

Evaluation of a nurse-led continence service in the south-west of Glasgow, Scotland

This paper reports the results of a pilot study of a nurse-led continence promotion service in both the community and a local nursing home. Telephone and written referrals were made to the service from 28 primary care teams in Glasgow, Scotland. In the nursing home all patients were assessed and an appropriate management plan implemented. A full assessment was carried out in all community patients, including an appraisal of contributory factors, urinalysis and diaries of food and drink intake. A management plan suited to the patient was then implemented. Patients' levels of incontinence in both arms of the study were assessed objectively using the Lagro-Janssen method. The cost incurred in both arms of the study were measured. There was a 69% improvement in the level of incontinence in the community group compared with 30% in the residents wing and 13% in the hospital wing. The savings in the nursing home amounted to Pounds 4152 in the residents' wing and Pounds 1959 in the hospital wing. In summary, a nurse dedicated to urinary incontinence in the community allows improved management, a greater level of awareness and results in resource savings, whilst increasing patient accessibility to a service.     

Personal computer teleradiology interhospital image transmission to facilitate tertiary pediatric telephone consultation and patient transfer: soft-tissue lateral neck and elbow radiographs

Although teleradiology systems are available commercially, they are expensive ($30,000), and different makes are incompatible with each other, making them unusable for interhospital image transfers. Standard components were added to a personal computer (PC) to build a functional teleradiology unit capable of interhospital image transmission at a low cost ($600 upgrade). This PC teleradiology system was studied to assess its accuracy in the interpretation of soft-tissue lateral neck x-rays with epiglottitis or retropharyngeal abscesses and elbow x-rays with joint effusions, fractures, or both. A radiologist and a pediatric emergency physician were asked to read the PC teleradiology images. Both physicians read 13 of 13 soft-tissue lateral neck x-rays and 15 of 15 elbow x-rays correctly. This study supports the premise that PC teleradiology can be used to facilitate telephone consultation and patient transfers between tertiary pediatric emergency centers by transmitting pertinent radiographic information over a phone line. Although verbal communication can often suffice in a telephone consultation or transfer, there are many instances when visualizing a radiographic image such as an x-ray or computed tomography scan can provide important information that cannot be optimally described verbally. Rural hospitals can form interhospital image transmission links with tertiary center resources. Tertiary centers may elect to organize interhospital image transmission and referral networks with their rural hospital sources.     

Comparison of cost effectiveness of directly observed treatment (DOT) and conventionally delivered treatment for tuberculosis: experience from rural South Africa

OBJECTIVE: To conduct an economic evaluation of directly observed treatment (DOT) and conventionally delivered treatment for the management of new cases of tuberculosis in adults. DESIGN: Community based directly observed treatment, which has been implemented in the Hlabisa district of South Africa since 1991, was compared with a conventional approach to tuberculosis treatment widely used in Africa. Each was assessed in terms of cost, cost effectiveness, and feasibility of implementation within existing resource constraints. SETTING: Hlabisa Health District, South Africa. SUBJECTS: Adult patients with new cases of tuberculosis on smear testing; the number of cases increased from 20 per month to over 100 from 1991 to 1996. MAIN OUTCOME MEASURES: Cost of case management in 1996, cost effectiveness in terms of the cost per case cured, and bed requirements in comparison with bed availability for the 1990, 1993, and 1996 caseload. Costs are expressed in US dollars at values for 1996. RESULTS: Directly observed treatment was 2.8 times cheaper overall than conventional treatment ($740.90 compared with $2047.70) to deliver. Directly observed treatment worked out 2.4-4.2 times more cost effective, costing $890.50 per patient cured compared with either $2095.60 (best case) or $3700.40 (worst case) for conventional treatment. The 1996 caseload of tuberculosis required 47 beds to be dedicated to tuberculosis to implement directly observed treatment, whereas conventionally delivered treatment would have required 160 beds; the current number of beds for tuberculosis treatment in Hlabisa is fixed at 56. CONCLUSIONS: Because of the reduced stay in hospital, directly observed treatment is cheaper, more cost effective, and more feasible than conventional treatment in managing tuberculosis in Hlabisa, given the existing hospital bed capacity and the escalating caseload due to the HIV/AIDS epidemic. Such results may hold elsewhere, and wherever conventional tuberculosis management is practised a switch to directly observed treatment will increase hospital capacity to cope with a growing caseload.     

Tuberculin skin testing of hospitalized patients

OBJECTIVES: We sought to define the prevalence of tuberculin skin test (TST) positivity in a group of newly hospitalized patients, to identify risk factors for positive tests, and to examine the impact of testing on infection control practices. DESIGN: Unblinded cohort study over 5 days in July 1992. SETTING: A 1,000-bed university-affiliated hospital. PATIENTS: All patients admitted (excluding obstetric patients and newborns) were interviewed. Patients without a history of tuberculosis (TB) or a positive TST were offered a TST with Candida and tetanus controls. RESULTS: Of 346 patients offered the test, 21 (6%) had a prior history of TB or a positive TST, and 36 (10%) declined to participate; 279 of the remaining 289 completed the study. Anergy was demonstrated in 94 (33.7%) of 279 patients. New positive TSTs were identified in 19 (10.3%) of 185 nonanergic patients. Of the 19 TST-positive patients, 6 (32%) had infiltrates on chest radiographs and were evaluated for active TB. One patient was treated empirically for active TB, and five received isoniazid prophylaxis. Risk factors for a new positive TST included age (odds ratio [OR], 1.56 per decade of life; P = .021), African American race (OR, 4.81; P = .008), alcohol abuse (OR, 5.53; P = .005), and peptic ulcer disease (OR, 4.53; P = .017). Risk factors for anergy included admission to a surgical service (OR, 2.1; P = .006), current use of steroids (OR, 2.65; P = .005), and human immunodeficiency virus (HIV) infection (OR, undefined; P = .034). CONCLUSIONS: Despite a high rate of anergy, routine tuberculin skin testing identified a substantial number of patients with TB infection who might otherwise have gone unrecognized.     

Overview of the rectus abdominis myocutaneous flap in head and neck reconstruction

OBJECTIVES: To examine the current in-patient respite service in terms of the type of patient served, whether their care could be provided satisfactorily outwith hospital and whether hospital resources could be used more efficiently. DESIGN: Multi-disciplinary assessment of subjects and completion of recording form. SETTING: Inverclyde and Renfrew, Scotland (population 288,000). SUBJECTS: All elective respite admissions to Merchiston Hospital during the period 1.1.93 to 31.12.93. RESULTS: Twenty-six patients received respite care in the period studied. Seventy-three per cent had severe/profound handicap, and all had at least one additional problem to their learning disability. We found the majority (73%) would require extra nursing care in hospital. Current social work respite placements do not cater for this level of disability. Respite bed occupancy rates are lower during the week than at the weekend. CONCLUSIONS: Most patients receiving respite care in our hospital are a highly dependent group whose needs cannot be met by local social work services. There is a need for more accurate planning of respite provision to maximise the efficient use of beds.     

A case of Kartagener's syndrome associated with pulmonary tuberculosis, pneumothorax and pulmonary aspergilloma

A case of Kartagener's syndrome associated with multiple pulmonary complication was presented. A 19-year-old man was admitted to our hospital because of pulmonary tuberculosis in May 1972. He had been diagnosed as Kartagener's syndrome because of the presence of chronic parasinusitis, bronchiectasis and complete situs inversus. His chest radiographs in Dec 1972 revealed left pneumothorax. Chest radiographs in Aug 1975 appeared aspergilloma in the right middle lung field. He was administrated intravenous and oral anti-fungal agent and transbronchial installation of Amphotericin-B because of hemoptysis. Chest radiographs in July 1980 resolved the aspergilloma and his symptom were also resolved. In 1996, he had no pulmonary symptoms and respiratory failure. We consider that the Kartagener's syndrome was good prognosis with adequate pulmonary therapy.     

Suspected lamotrigine-induced toxic epidermal necrolysis

OBJECTIVE: To describe a patient who developed toxic epidermal necrolysis (TEN) possibly secondary to lamotrigine use. CASE SUMMARY: A 74-year-old white man with a history of probable complex partial seizures was admitted to the neurology service for a prolonged postictal state. His antiepileptic regimen was changed while he was in the hospital to include lamotrigine. After 19 days of hospitalization and 14 days of lamotrigine therapy, the patient became febrile. The next day he developed a rash which progressed within 4 days to TEN, diagnosed by skin biopsy. All suspected drugs were discontinued, including lamotrigine. The patient was treated with hydrotherapy in the burn unit. His symptoms improved and he was discharged from the hospital 26 days after the rash developed. DISCUSSION: During lamotrigine's premarketing clinical trials, the manufacturer reported several cases of Stevens-Johnson syndrome and TEN. There are several published case reports of lamotrigine-induced severe skin reactions. All of these reports included patients being treated with both valproic acid and lamotrigine. Our patient was exposed to phenytoin, carbamazepine, clindamycin, and lamotrigine, but not valproic acid. The patient reported prior use of phenytoin with no skin rash. Carbamazepine was the antiepileptic drug the patient was maintained on prior to his hospital admission, and the symptoms of TEN resolved while he was still receiving carbamazepine. The patient received only two doses of clindamycin, which makes this agent an unlikely cause of TEN. CONCLUSIONS: Because of the temporal relationship of the onset of the patient's rash and several drugs that are known to cause severe rashes, it is not certain which drug was the definite culprit. However, based on the evidence from the literature, lamotrigine appears to be the causative agent.
