RESUMO
BACKGROUND: Basic bleeding control (BCon) techniques can save lives globally but the knowledge is not widespread in low-income countries where trauma is a common cause of death. Short-term surgical missions (STSMs) are an effective route to share this public health initiative around the world. MATERIALS AND METHODS: Over 2017-2018, the International Surgical Health Initiative organized STSMs to locations in Sierra Leone, Bangladesh, Peru, and Ghana. The hour-long official American College of Surgeons Basic Bleeding Control course was offered to host participants several times over the course of the mission. Data including number and size of classes, type of trainee, instructors trained, and success rate in demonstrating acquisition of core BCon principles and techniques were collected. RESULTS: Over the course of four, week-long STSMs, 748 people were successfully trained in BCon over 27 sessions, with an average of 28 trainees and up to four instructors per class. One-hundred percent of trainees demonstrated acquisition of required skills proficiency. Trainees included health care workers and those in public security roles. CONCLUSIONS: Concurrent with a short-term surgical mission, a substantial number of health care providers and would-be bystanders can be trained in BCon in countries most impacted by trauma. Local instructors can be trained to teach BCon independently to sustain the initiative. STSMs are a feasible modality to teach bleeding control techniques to an international audience that does not have rapid access to effective prehospital care.

BACKGROUND: We present a case of intracardiac rhabdomyosarcoma associated with cardiopulmonary instability which was diagnosed by emergency providers using point-of-care echocardiography. CASE REPORT: A previously healthy 49-year-old man presented to the Emergency Department with progressive dyspnea and hypotension. Emergency providers identified a left atrial mass using point-of-care ultrasound. Expedited advanced imaging and surgical management showed a malignant cardiac rhabdomyosarcoma. Why should an emergency physician be aware of this? This case report highlights the utility of point-of-care ultrasound in the work-up of patients with undifferentiated dyspnea and hypotension, even in cases of rare diagnoses. Early diagnosis and management of both benign and malignant intracardiac tumors is essential to preoperative planning and patient prognosis. Ultrasound findings consistent with intracardiac masses should be recognized and used to guide further consultation, advanced imaging, and treatment.

High-potency marijuana wax smoked via dabbing is a newly encountered phenomenon with relevance to prehospital care providers and emergency physicians.The extract is only recently described in current peer-reviewed literature. The drug may produce paranoia and psychosis and mimic psychiatric problems. The synthetic process for this drug poses a risk for both fire and explosions creating burns and blast injuries. These four cases were encountered in a single ED in Los Angeles in a three-week period, suggesting this could be the tip of an emerging public health problem. All four of these patients were complex cases requiring advanced imaging and ICU care. Emergency personnel need to appreciate this new trend and the implications for pre-hospital care, disposition and ED treatment of these patients.

BACKGROUND: Baseline disparities in non-discretionary risk factors, i.e., those not readily altered, like family size and work environment, appear to underlie the disproportionate COVID-19 infection rates seen among Hispanic persons and, at surge onsets, Black persons. No study has systematically compared such risk factors by race/ethnicity among infected individuals. METHODS: Using a cross-sectional survey, we compared household, job, and socioeconomic characteristics among 260 Hispanic, non-Hispanic Black, and non-Hispanic White adults with confirmed or probable COVID-19 in New York from March to May 2020. We used logistic regression to identify independent relationships. RESULTS: In bivariate analysis, we found significant differences by race/ethnicity in the following: (1) rates of household crowding (p < 0.001), which were highest for Hispanic patients (45.1%) and lowest for White patients (0.9%); (2) rates of non-healthcare frontline work (p < 0.001), which were highest for Hispanic patients (71.0% of those employed) and lowest for White patients (31.4%); (3) rates of working close to people (p < 0.001), which were highest for Black patients (69.4%) and lowest for Hispanic patients (32.3%); and (4) rates of frontline healthcare work (p = 0.004), which were higher for Black (44.9%) and White (44.3%) patients than Hispanic patients (19.4%). Adjusting for covariates eliminated most differences but not that for household crowding. CONCLUSIONS: Non-discretionary COVID-19 risk factors among patients in the initial surge differed substantially by race/ethnicity. Socioeconomic factors explained most differences, but household crowding was independently associated with Hispanic ethnicity. Our findings highlight the ongoing need for universal safeguards for US frontline workers, including mandated paid sick leave and expanded affordable housing options.

BACKGROUND: Despite reported higher rates and worse outcomes due to COVID-19 in certain racial and ethnic groups, much remains unknown. We explored the association between Hispanic ethnicity and outcomes in COVID-19 patients in Long Island, New York. METHODS: We conducted a retrospective cohort study of 2,039 Hispanic and non-Hispanic Caucasian patients testing positive for SARS-CoV-2 between March 7 and May 23, 2020, at a large suburban academic tertiary care hospital near New York City. We explored the association of ethnicity with need for intensive care unit (ICU), invasive mechanical ventilation (IMV), and mortality. RESULTS: Of all patients, 1,079 (53%) were non-Hispanic Caucasians and 960 (47%) were Hispanic. Hispanic patients presented in higher numbers than expected for our catchment area. Compared with Caucasians, Hispanics were younger (45 years vs. 59 years), had fewer comorbidities (66% with no comorbidities vs. 40%), were less likely to have commercial insurance (35% vs. 59%), or were less likely to come from a nursing home (2% vs. 10%). In univariate comparisons, Hispanics were less likely to be admitted (37% vs. 59%) or to die (3% vs. 10%). Age, shortness of breath, congestive heart failure (CHF), coronary artery disease (CAD), hypoxemia, and presentation from nursing homes were associated with admission. Male sex and hypoxemia were associated with ICU admission. Male sex, chronic obstructive pulmonary disease, and hypoxemia were associated with IMV. Male sex, CHF, CAD, and hypoxemia were associated with mortality. After other factors were adjusted for, Hispanics were less likely to be admitted (odds ratio = 0.62, 95% confidence interval = 0.52 to 0.92) but Hispanic ethnicity was not associated with ICU admission, IMV, or mortality. CONCLUSIONS: Hispanics presented at higher rates than average for our population but outcomes among Hispanic patients with COVID-19 were similar to those of Caucasian patients.

We report an unusual case of a 24-year-old girl with a history of recurrent hypokalemic paralysis episodes and skin lesions on the lower limbs and buttocks, both of which had an acute evolution. In subsequent investigations, the patient also had nephrocalcinosis, nephrolithiasis, hyperchloremic metabolic acidosis and persistent alkaline urinary pH. The findings were consistent with distal renal tubular acidosis as the cause of hypokalemic paralysis. Clinical findings, immunological tests and the result of skin biopsy suggested primary Sjögren's syndrome as an underlying cause. The patient developed azotemia due to obstructive nephrolithiasis. All the features presented in this case are an unusual manifestation of distal renal tubular acidosis; so far, we are not aware of a similar report in the literature.

INTRODUCTION: . Failure to recover erectile function after radical prostatectomy (RP) may result from venous leak as a sequela of neuropraxia-induced erectile tissue damage. Venous leak portends a poor prognosis for erections recovery as well as phosphodiesterase type 5 inhibitor (PDE5i) response. AIMS: To define the impact of RP nerve-sparing status on venous leak prevalence and chronology. STUDY POPULATION: men who underwent RP for localized prostate cancer, had functional erections prior to RP, developed postoperative erectile dysfunction (ED), had a Doppler ultrasonography within 6 months of RP, and did not receive any ED treatment for the first 6 months after RP other than on-demand PDE5i. MAIN OUTCOME MEASURES: Venous leak prevalence and erectile function recovery at different time-points. RESULTS: Data on 142 patients were analyzed, mean age: 58 +/- 16 years. Sixty percent had bilateral nerve-sparing (BNS) surgery, 20% unilateral nerve-sparing (UNS) surgery, and 20% non-nerve-sparing (NNS) surgery. Eleven percent and 21% had venous leak by 3 and 6 months, respectively. Venous leak prevalence by 6 months was 7%, 11%, and 75% for BNS, UNS, and NNS surgery (P < 0.001). Mean end-diastolic velocity was 1.8, 2.1, and 7.2 cm/second for the three groups (P < 0.01). The only patients developing venous leak prior to 3 months were NNS patients, one-third of NNS-associated venous leak occurring before this time-point. At 18 months, the proportion of men having return of unassisted erections was 49%, 42%, and 7% with mean erectile function domain scores of 21, 18, and 12, and PDE5i response rates were 72%, 64%, and 12% for the three groups, respectively. CONCLUSIONS: Nerve-sparing status impacts heavily upon the prevalence and the chronology of venous leak development post-RP. NNS RP is associated with early development of venous leak, increased prevalence of venous leak, and reduction in return of natural erections.

INTRODUCTION: World Health Organization data for Madagascar reveal that the nation's under age five mortality rate is 56/1000, and that its maternal mortality rate is 440/100,000. Malaria, leprosy, plague, and tuberculosis remain significant communicable disease threats. Malnutrition rates are improving but continue to impact negatively on the general health of the Malagasy population, especially in the southern region with its 1.9 million inhabitants. There are no emergency medicine (EM) training programs to serve the southern half of Madagascar, which has a large urban population in Fianarantsoa. This study aimed to assess the need for and potential feasibility of an emergency medicine training program in southern Madagascar. METHODS: We met with the institutional leadership on site at the university hospital in Fianarantsoa. A needs assessment was performed on multiple domains. Domain 1: existing hospital infrastructure and its physical plant and emergency centre (EC) space allotment. Domain 2: existing clinical and technological resources. Domain 3: educational resources and the existing curriculum for EM. Domain 4: medical student educational program and availability of prospective residency candidates. Domain 5: pre-hospital care and emergency medical services. RESULTS: The size of the EC is adequate for the current census. Clinical resources are typical of many developing countries, with significant need for technological advancement and support, which we delineate in the body of our paper. There is an existing curriculum in Antananarivo and in Majanga, as well as one available through the African Federation for Emergency Medicine. The medical school in the area is relatively new, with graduating classes numbering approximately 30. There is no organised pre-hospital care system, no 9-1-1 equivalent, and no pre-hospital treatment from within metropolitan Fianarantsoa. CONCLUSIONS: While the needs assessment indicates substantial need for emergency medicine development in southern Madagascar, the yield (particularly for the metropolitan Fianarantsoa area) would serve the population well.

RESUMO Relatamos um caso incomum de uma jovem de 24 anos com história de episódios recorrentes de paralisia hipocalêmica e lesões cutâneas em membros inferiores e nádegas, ambas de evolução aguda. Em investigações subsequentes, verificou-se que a paciente apresentava nefrocalcinose, nefrolitíase, acidose metabólica hiperclorêmica e pH urinário persistentemente alcalino. Os achados foram consistentes com acidose tubular renal distal como causa da paralisia hipocalêmica. Achados clínicos, exames imunológicos e o resultado da biópsia de pele foram compatíveis com a síndrome de Sjögren primária como causa subjacente. A paciente evoluiu com azotemia em decorrência da nefrolitíase obstrutiva. Todas as características apresentadas nesse caso são uma manifestação incomum de acidose tubular renal distal; até o momento, não temos conhecimento de um relato semelhante na literatura.

BACKGROUND: Chronic renal failure patients frequently show malnourishment. OBJECTIVE: The food intake and the nutritional status of 165 chronic renal failure patients on maintenance hemodialysis were studied. METHODS: Nutritional status of 165 patients were studied by anthropometry, biochemical measurements, protein nitrogen appearance rate (PNA) and a average food intake. RESULTS: The results show that in mean the percent standard body weight, the body mass index (BMI), the mid arm muscle circumference (MAMC) and the triceps skinfold thickness (TSF) were adequate, however, 38% of women and 27% of men had the TSF bellow the 5th percentile; 39% of men and 2% of women presented MAMC bellow the 5th percent, showing that lose body fat in both sexs and the muscle stores in men. Energy intake was 29.5 +/- 10.2 Kcal/kg/day and 74% of the patients consumed less than 35 Kcal/kg/day, the recommended level for this population. Although the protein intake was in the recommended range (1.32 +/- 0.4 g/kg/day), 47% of the patients consumed less than 1.2 g/Kg/day. Mean serum albumin was 3.96 +/- 0.36 g/dL (normal value). According to TSF and of MAMC criteria (the reference was the 5th percentile), 74 (44.8%) patients were classified as malnourished. CONCLUSIONS: The frequency of malnutrition is high in our population and the poor food intake may contribute to this condition.

Reliably diagnosing pregnancy in women presenting with nonspecific abdominal pain can be lifesaving. If diagnostic tests are unreliable, however, valuable time and resources can be wasted pursuing unnecessary and potentially harmful interventions. After four false positive-urine pregnancy tests in one week, we began investigating the laboratory's entire process involving the UPreg tests. We discovered that, as is common in resource-poor settings, the laboratory repeatedly reused test tubes. We found that the false-positive tests resulted from performing the UPreg tests in test tubes that were improperly cleaned and, for the most part, had been used immediately beforehand to test women coming into the maternity ward. Sufficient residua from the pregnant women's high ß-HCG levels had remained in the test tubes to cause subsequent false-positive results in our emergency ward patients. Although pregnancy can now be reliably diagnosed with inexpensive, disposable and simple tests, these tests must not only be used properly, but also, when used in the laboratory, be accompanied by appropriate cleaning and quality-control procedures. This is particularly essential in resource-constrained environments.

INTRODUCTION: The International Index of Erectile Function (IIEF) has become the gold standard inventory for the assessment of sexual function in drug trials and in clinical research. Normalization of the erectile function domain (EFD) score, an end of treatment score of 26 or higher, is an end-point that is currently being used routinely in drug trials. It has been our experience that some men with scores less that 26 on a sexual pharmaceutical are content with their sexual function. We undertook this study to define what proportion of men with EFD scores <26 are satisfied with their therapeutic response. METHODS: 100 consecutive patients who had presented to a sexual health clinic and who had used sildenafil citrate on at least 4 occasions completed the IIEF pertaining to their sildenafil response. They were also asked questions, pertaining to their ability to have sexual intercourse (Q1), their satisfaction with their erectogenic medication (Q2), the ability of the medication to improve erectile rigidity (Q3), and the ability of the medication to improve their ability to have sexual intercourse (Q4). Patients were subcategorized into 4 groups based on treatment IIEF scores (>/=26, 22-25, 18-21, and 11-17). The IIEF scores were compared to the responses to the global assessment questions. MAIN OUTCOME MEASURES: The mean patient age was 58 +/- 22 years. For Q1 and Q2, for each subcategory, there was a significant difference in the percentage of men answering definitely, somewhat, or not at all. In the group with EFD scores 22-25, 67% agreed at least somewhat with Q1 and 66% with Q2. In this group 84% and 78% responded in the affirmative to Q3 and Q4, respectively. No patient with an EFD score <22 definitely agreed with Q1 or Q2. CONCLUSIONS: These data indicate that a significant proportion of patients with EFD scores 21-25 can have sexual relations that are satisfactory and that they are satisfied with their erectogenic medication.

OBJECTIVES: To evaluate the effectiveness of penile vibratory stimulation for the management of retarded orgasm. Retarded orgasm, a condition characterized by difficulty achieving orgasm and ejaculation, is one of the most recalcitrant of the male sexual dysfunctions. Currently, no evidence-based treatments have been proven to ameliorate this condition. METHODS: Men who had a complete inability to achieve an orgasm during sexual relations in the previous 3 months were instructed in the use of penile vibratory stimulation. The men's responses were measured by self-report of orgasm function and using the orgasm and satisfaction domains of the International Index of Erectile Function. The responses were assessed at baseline (admission into the study) and at 3 and 6 months. RESULTS: A total of 36 men met the inclusion criteria, and 72% reported the restoration of orgasm. These responders reported that orgasm during sexual relations occurred 62% of the time. A statistically and clinically significant increase occurred in the orgasm and satisfaction domains of the International Index of Erectile Function between the baseline visit and the 3-month follow-up visit. These gains were sustained at 6 months. CONCLUSIONS: Penile vibratory stimulation is an effective treatment for retarded orgasm. Penile vibratory stimulation should be integrated into current cognitive-behavioral sex therapy techniques to achieve maximal effectiveness and satisfaction.

OBJECTIVES: To evaluate the impact of normalization of testosterone levels in men with documented hypogonadism and erectile dysfunction on erectile function and sexual satisfaction. Although the data support the role of testosterone in the preservation of libido and nocturnal erectile function, the evidence supporting the use of testosterone supplementation in hypogonadal men with erectile dysfunction is weak. METHODS: This analysis used two validated questionnaires, the International Index of Erectile Function and the Erectile Dysfunction Inventory of Treatment Satisfaction, in a serial fashion at baseline (before treatment) and 1, 3, and 6 months after the achievement of a therapeutic testosterone level. RESULTS: A total of 32 men met all inclusion criteria; 69% of men achieved therapeutic testosterone levels using transdermal testosterone gel, 19% required a transdermal patch, and 12% required intramuscular delivery. Statistical significance was reached for the difference between the baseline and 1-month International Index of Erectile Function erectile function domain score and all post-treatment International Index of Erectile Function libido scores. A steady decrease occurred in the Erectile Dysfunction Inventory of Treatment Satisfaction scores from the 1 to 6-month values that reached statistical significance. CONCLUSIONS: In men with documented hypogonadism and erectile dysfunction, normalization of serum testosterone levels was associated with only short-term improvement in erectile function and sexual satisfaction. The use of testosterone supplementation in this population for the treatment of erectile dysfunction is questionable.

PURPOSE: Despite the advent of nerve sparing radical prostatectomy some men experience erectile dysfunction. Many of these men have vasculogenic erectile impairment in the form of arterial insufficiency or venous leakage. Recent data imply that early postoperative injection therapy may decrease the rate of erectile dysfunction. We defined hemodynamic patterns in patients who underwent bilateral nerve sparing radical prostatectomy to assess the chronology of venous leakage development and explore the correlation of hemodynamic profiles with the return of functional erection 12 months postoperatively. MATERIALS AND METHODS: Patients with excellent preoperative erectile function who underwent bilateral nerve sparing surgery and had no pharmacological support for erectile dysfunction in the initial 12 months after surgery received vascular evaluation at presentation. Vascular evaluation involved cavernosometry or penile ultrasonography. Patients were then interviewed again at least 12 months postoperatively to assess the ability to achieve sexual intercourse. RESULTS: Our study group comprised 96 men with a mean age plus or minus standard deviation of 54 +/- 12 years who met all inclusion criteria. All patients had pathologically proved organ confined disease. Mean time to the initial postoperative presentation was 6 +/- 5 months. Patients were divided into 4 groups according to the time of vascular studies postoperatively, namely less than 4 to 8, 9 to 12 and greater than 12 months. Normal vascular status, arterial insufficiency and venous leakage were diagnosed in 35%, 59% and 26% of the group, respectively. No difference in the incidence of arterial insufficiency was noted in the 4 time groups. Time postoperatively was significantly associated with the incidence of venous leakage (14% at less than 4 months and 35% at between 9 and 12). In regard to the correlation of the vascular diagnosis with the return to functional erection 47% of the normal, 31% of the arteriogenic and 9% of the venous leakage group achieved sexual intercourse 12 months postoperatively. CONCLUSIONS: These data imply that the longer the duration of erectile dysfunction after radical prostatectomy, the greater the risk of venous leakage. Furthermore, it appears that the prognosis for the return of functional erection is worst when venous leakage is present.

OBJECTIVE: To define the type of orgasmic dysfunction in men after radical prostatectomy (RP), as absence of orgasm and orgasmic pain are recognized complaints, and changes in orgasm may lead to significant sexual dissatisfaction. PATIENTS AND METHODS: Using an unvalidated questionnaire, demographic, erectile function and orgasmic function questions were answered by 239 patients who had previously undergone a retropubic RP. RESULTS: Of the 239 patients, 22% had no change in orgasm intensity, 37% reported a complete absence of orgasm, 37% had decreased orgasm intensity and 4% reported a more intense orgasm after RP than before. Pain during orgasm (dysorgasmia) occurred in 14% of the patients; in these respondents the pain reportedly occurred always (with every orgasm) in 33%, frequently in 13%, occasionally in 35%, and rarely in 19%. Most patients (55%) had orgasm-associated pain for <1 min. CONCLUSIONS: These results indicate that orgasmic functional changes are relatively common after RP and are worth considering by clinicians and researchers.

BACKGROUND: Endovascular stent-graft (ESG) repair of abdominal aortic aneurysm (AAA) has emerged as an alternative to open surgery. The role of ESG in patients with challenging medical and anatomic problems remains an area of general debate. This study reviews an experience with stent grafts to treat patients with AAA and atheromatous embolization syndrome (AES) presenting with chronic distal embolization (CDE). METHODS: Over a 5-year period 660 patients with AAA were treated with aortic stent grafts. Patients with AAA and ischemic ulcerations or toe gangrene due to CDE despite palpable foot pulses were investigated for successful aneurysm exclusion, resolution of ischemic symptoms, complications and survival. Follow-up averaged 15.3 +/- 14.9 months (range, 1 to 60 months). RESULTS: Nineteen patients had AAA and manifestations of CDE. The population (16 males/3 females) had a mean age of 79 +/- 7 years and mean aneurysm diameter of 5.5 cm. Renal insufficiency was present in 5/19 (26 %). Ischemia presented as ischemic ulcers (16/19 [84.2%]) or toe gangrene (3/19 [15.8%]). Stent grafts included 6 aortouniiliac and 13 bifurcated devices. Exclusion was achieved in all but 2 patients who had type II lumbar endoleaks. At 30-day postoperative follow-up, mortality was 0 % and resolution of CDE/ischemia was noted in 2 of 19 (10.5%) patients. Eight of 9 patients with follow-up of 1 year had complete resolution of their ischemic symptoms, with no recurrent manifestations of AES. Complications included progression of renal insufficiency over an 18-month period in 1 patient and an unstable expanding pararenal aortic neck in 1 patient. Foot ischemia persisted at 1 year in a patient with severe coexisting thoracic aortic disease despite successful AAA exclusion. Six (31.6%) patients died during a mean follow-up of 15.3 months from causes unrelated to their AAA. CONCLUSION: On the basis of this experience, stent-graft repair of AAA and CDE may be an effective strategy to prevent future embolization. Recognition of coexisting thoracic aortic disease is essential. ESG does not address the extremely high morbidity and mortality from cardiovascular causes in this population.

OBJECTIVES: Endovascular stent graft repair of abdominal aortic aneurysms (AAAs) prevents rupture by excluding the aneurysm sac from systemic arterial pressure. Current surveillance protocols after endovascular aneurysm repair (EVAR) follow secondary markers of sac pressurization, namely, endoleak and sac enlargement. We report the first clinical experience with the use of a permanently implantable, ultrasound-activated remote pressure transducer to measure intrasac pressure after EVAR. METHODS: Over 7 months, 14 patients underwent EVAR of an infrarenal abdominal aortic aneurysm with implantation of an ultrasound-activated remote pressure transducer fixed to the outside of the stent graft and exposed to the excluded aortic sac. Twelve patients received modular bifurcated stent grafts, and 2 patients received aortouniiliac devices. Intrasac pressures were measured directly with an intravascular catheter and by the remote sensor at stent-graft deployment. Follow-up sac pressures were measured with a remote sensor and correlated with systemic arterial pressure at every follow-up visit. Mean follow-up was 2.6 +/-1.9 months. RESULTS: Excellent concordance was found between catheter-derived and transducer-derived intrasac pressssure intraoperatively. Pulsatile waveforms were seen in all functioning transducers at each evaluation interval. One implant ceased to function at 2 months of follow-up. In 1 patient a type I endoleak was diagnosed on 1-month computed tomography (CT) scans; 3 type II endoleaks were observed. Those patients with complete exclusion of the aneurysm on CT scans had a significant difference in systemic and sac systolic pressures initially (P <.001) and at 1 month (P <.001). Initial sac diastolic pressures were higher than systemic diastolic pressures (P <.001). The ratio of systemic to sac systolic pressure increased over time in those patients with complete aneurysm exclusion ( P <.001). Four of 6 patients with no endoleak and greater than 1-month follow-up had diminution of sac systolic pressure to 40 mm Hg or less by 3 months. CONCLUSION: This is the first report of a totally implantable chronic pressure transducer to monitor the results of EVAR in human beings. Aneurysm exclusion leads to gradual diminution of sac pressure over several months. Additional clinical follow-up will be necessary to determine whether aneurysm sac pressure monitoring can replace CT in the long-term surveillance of patients after EVAR.

OBJETIVO: Estudar a ingestäo alimentar e o estado nutricional de 165 pacientes com IRC em hemodiálise. MÉTODOS: O estado nutricional dos 165 pacientes foi estudado por meio de parâmetros antropométricos, bioquímicos, proteína equivalente do aparecimento do nitrogênio (PNA) e registro do consumo alimentar. RESULTADOS: Os resultados mostram que a média dos percentuais de adequaçäo do peso, do índice de massa corporal (IMC), da circunferência muscular do braço (CMB) e da prega cutânea do tríceps (PCT) estavam adequados, porém 38 por cento das mulheres e 27 por cento dos homens apresentaram PCT abaixo do percentil 5; 39 por cento dos homens e 2 por cento das mulheres apresentaram CMB inferio-res ao percentil 5, evidenciando uma perda de gordura corporal em ambos os sexos e de massa muscular nos homens. O consumo de energia foi de 29,5 ± 10,2 kcal/kg/dia, e 74 por cento dos pacientes consumiam menos que as 35 kcal/kg/dia recomendadas para essa populaçäo. Apesar do consumo médio de proteína estar dentro do recomendado (1,32 ± 0,4 g/kg/dia), 47 por cento dos pacientes consumiam menos que 1,2 g/kg/dia. A média da albumina sérica foi de 3.96±0.36 g/dL (valor considerado normal). De acordo com as medidas de PCT e/ou CMB (ú 5 percentil do padräo de referência), 74 (44,8 por cento) pacientes foram classificados como desnutridos. CONCLUSÄO: A desnutriçäo é freqüente em nossa populaçäo e o reduzido consumo alimentar pode contribuir para essa condiçäo
