Biologic Disease-Modifying Antirheumatic Drugs Do Not Increase Risk for Prosthetic Joint Infection in Setting of Total Knee Arthroplasty.

Over 25% of patients with rheumatoid arthritis (RA) are expected to undergo a joint replacement during their lifetime. Current practice guidelines recommend withholding biologic therapy 1 week prior to total hip arthroplasty, given its immunosuppressive effects. Most patients are on a regimen including biologic and nonbiologic therapy; however, the individual influences of these therapies are not well understood in the setting of total knee arthroplasty (TKA). Therefore, we sought to compare biologic, nonbiologic, and recipients of both types of therapy in patients with RA undergoing TKA. We specifically assessed (1) medical complications at 90 days; (2) surgical complications up to 1 year; and (3) independent risk factors for prosthetic joint infections (PJIs).A retrospective review was conducted using a national, all-payer database for patients undergoing primary TKA from January 2010 to April 2020 (n = 1.97 million). Patients diagnosed with RA were then separated into at least 1-year users of biologic (n = 3,092), nonbiologic (28,299), or dual (n = 10,949) therapy. Bivariate analyses were utilized to assess for 90-day medical and up to 1-year surgical outcomes. Additionally, multivariate regression models were utilized to assess for independent risk factors.The incidence and odds ratio for medical/surgical outcomes were equivocal among the biologic, nonbiologic, and recipients receiving both types of therapy (p > 0.061). No differences were observed between the type of therapy as additional risk factors for infection (p > 0.505). However, glucocorticoids at 90 days and alcohol abuse, diabetes mellitus, obesity, as well as tobacco use were identified as additional risk factors for PJI(p < 0.036).No appreciable differences in medical or surgical outcomes were associated with the independent use of biologic, nonbiologic, or recipients of both types of therapy in patients with RA. Additionally, alcohol abuse, diabetes mellitus, glucocorticoids, obesity, and tobacco use conferred an increased risk of PJI. These results can serve as an adjunct to current practice guidelines.

Antibiotic Prophylaxis is Often Unnecessary for Screening Colonoscopies Following Total Knee Arthroplasty.

BACKGROUND: Incidence of bacteremia following screening colonoscopy is low, but risk of hematogenous spread causing prosthetic joint infection (PJI) may exist in total knee arthroplasty (TKA) patients. In multivariate analyses, we examined PJI risk among 3 TKA cohorts: (1) colonoscopy recipients given antibiotic prophylaxis; (2) colonoscopy recipients not given antibiotic prophylaxis; and (3) no colonoscopy. We assessed 90-day to 1-year (A) PJI risk and (B) risk factors for postcolonoscopy PJI. METHODS: We queried a national, all-payer database for primary TKA recipients from 2010 to 2020. Patients who had colonoscopies and who did (n = 2,558) or did not have antibiotic prophylaxis (n = 20,000) were identified. These were compared those who did not undergo colonoscopy (n = 20,000). The 20,000 patients were randomly selected to mitigate type-1 errors. Multivariate regressions compared PJI risk factors, such as alcohol abuse (AA), rheumatoid arthritis (RA), and diabetes. RESULTS: Both colonoscopy cohorts had no increased PJI risk compared to noncolonoscopy (odds ratio (OR) ≤ 2.20, P ≥ .064). Alcohol abuse, diabetes, and RA were found to be risk factors further enhancing likelihood of PJI for TKA patients not receiving antibiotics undergoing colonoscopies (OR ≥ 1.35, P ≤ .044). CONCLUSION: Overall, antibiotic prophylaxis does not decrease PJI risk following colonoscopy TKA recipients. After adjusting for known risk factors, both colonoscopy cohorts demonstrated similar PJI risks compared to the noncolonoscopy cohort. However, AA, diabetes, and RA were associated with further increased PJI risk for TKA patients undergoing colonoscopies compared to those who did not. Therefore, if undergoing colonoscopy after TKA, our findings suggest that most patients do not need to have antibiotics except for these high-risk patients.

Disparities in Elective and Nonelective Total Hip Arthroplasty.

BACKGROUND: Prior studies have shown disparities in utilization of primary and revision total hip arthroplasty (THA). However, little is known about patient population differences associated with elective and nonelective surgery. Therefore, the aim of this study was to explore factors that influence primary utilization and revision risk of THA based on surgery indication. METHODS: Data were obtained from 7,543 patients who had a primary THA from 2014 to 2020 in a database, which consists of multiple health partner systems in Louisiana and Texas. Of these patients, 602 patients (8%) underwent nonelective THA. THA was classified as "elective" or "nonelective" if the patient had a diagnosis of hip osteoarthritis or femoral neck fracture, respectively. RESULTS: After multivariable logistic regression, nonelective THA was associated with alcohol dependence, lower body mass index (BMI), women, and increased age and number of comorbid conditions. No racial or ethnic differences were observed for the utilization of primary THA. Of the 262 patients who underwent revision surgery, patients who underwent THA for nonelective etiologies had an increased odds of revision within 3 years of primary THA (odds ratio (OR) = 1.66, 95% Confidence Interval (CI) = 1.06-2.58, P-value = .025). After multivariable logistic regression, patients who had tobacco usage (adjusted odds ratio (aOR) = 1.36, 95% CI = 1.04-1.78, P-value = .024), alcohol dependence (aOR = 2.46, 95% CI = 1.45-4.15, P-value = .001), and public insurance (OR = 2.08, 95% CI = 1.18-3.70, P-value = .026) had an increased risk of reoperation. CONCLUSION: Demographic and social factors impact the utilization of elective and nonelective primary THA and subsequent revision surgery. Orthopaedic surgeons should focus on preoperative counseling for tobacco and alcohol cessation as these are modifiable risk factors to directly decrease reoperation risk.

Association Between Bariatric Surgery and Alcohol Use-Related Hospitalization and All-Cause Mortality in a Veterans Affairs Cohort.

Importance: Bariatric surgery procedures, in particular Roux-en-Y gastric bypass (RYGB), have been associated with subsequent alcohol-related complications. However, previous studies lack data to account for changes in body mass index (BMI) or alcohol use over time, which are key potential confounders. Objective: To evaluate the association between RYGB, sleeve gastrectomy, or gastric banding on subsequent alcohol use disorder (AUD)-related hospitalization and all-cause mortality as compared with referral to a weight management program alone. Design, Setting, and Participants: This cohort study included 127 Veterans Health Administration health centers in the US. Patients who underwent RYGB, sleeve gastrectomy, or gastric banding or who were referred to MOVE!, a weight management program, and had a BMI (calculated as weight in kilograms divided by height in meters squared) of 30 or greater between January 1, 2008, and December 31, 2021, were included in the study. Exposures: RYGB, sleeve gastrectomy, or gastric banding or referral to the MOVE! program. Main Outcomes and Measures: The primary outcome was time to AUD-related hospitalization from the time of bariatric surgery or MOVE! referral. The secondary outcome was time to all-cause mortality. Separate propensity scores were created for each pairwise comparison (RYGB vs MOVE! program, RYGB vs sleeve gastrectomy, sleeve gastrectomy vs MOVE!). Sequential Cox regression approaches were used for each pairwise comparison to estimate the relative hazard of the primary outcome in unadjusted, inverse probability treatment weighting (IPTW)-adjusted (generated from the pairwise logistic regression models), and IPTW-adjusted approaches with additional adjustment for time-updating BMI and categorical Alcohol Use Disorders Identification Test-Concise scores. Results: A total of 1854 patients received RYGB (median [IQR] age, 53 [45-60] years; 1294 men [69.8%]), 4211 received sleeve gastrectomy (median [IQR] age, 52 [44-59] years; 2817 men [66.9%]), 265 received gastric banding (median [IQR] age, 55 [46-61] years; 199 men [75.1%]), and 1364 were referred to MOVE! (median [IQR] age, 59 [49-66] years; 1175 men [86.1%]). In IPTW Cox regression analyses accounting for time-updating alcohol use and BMI, RYGB was associated with an increased hazard of AUD-related hospitalization vs MOVE! (hazard ratio [HR], 1.70; 95% CI, 1.20-2.41; P = .003) and vs sleeve gastrectomy (HR, 1.98; 95% CI, 1.55-2.53; P < .001). There was no significant difference between sleeve gastrectomy and MOVE! (HR, 0.76; 95% CI, 0.56-1.03; P = .08). While RYGB was associated with a reduced mortality risk vs MOVE! (HR, 0.63; 95% CI, 0.49-0.81; P < .001), this association was mitigated by increasing alcohol use over time. Conclusions and Relevance: This cohort study found that RYGB was associated with an increased risk of AUD-related hospitalizations vs both sleeve gastrectomy and the MOVE! program. The mortality benefit associated with RYGB was diminished by increased alcohol use, highlighting the importance of careful patient selection and alcohol-related counseling for patients undergoing this procedure.

A Prospective Cohort of Alcohol Use and Alcohol-related Problems Before and After Metabolic and Bariatric Surgery in Adolescents.

OBJECTIVE: To describe alcohol use, alcohol-related harm, and alcohol-related problems preoperatively and up to 8 years following metabolic and bariatric surgery (MBS) in adolescents. BACKGROUND: Risk for alcohol use and alcohol use disorders (AUD) increases post-Roux-en-Y gastric bypass and vertical sleeve gastrectomy in adults. However, data are lacking in adolescents who undergo MBS. METHODS: This study includes 217 adolescents (aged 13-19 y) enrolled in a 5-center prospective cohort study who underwent Roux-en-Y gastric bypass or vertical sleeve gastrectomy (2007-2011) and reported alcohol use preoperatively and annually postoperatively for up to 8 years. Time to elevated Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) score, alcohol-related harm, and alcohol-related problems were analyzed with Kaplan-Meier estimates of cumulative incidence. RESULTS: Preoperatively, the median age was 17 years; the median body mass index was 51 kg/m 2 . Alcohol use frequency and average quantity of drinks per drinking day increased postoperatively (2% consumed alcohol 2-4 times/month 6 months versus 24% 8 years postoperatively, P <0.001; 2% consumed≥3 drinks per drinking day 6 months versus 35% 8 years postoperatively, P <0.001). Cumulative incidence of postoperative onset elevated AUDIT-C score, alcohol-related harm, and alcohol-related problems at year 8 were 45% (95% CI:37-53), 43% (95% CI:36-51), and 47% (95% CI:40-55), respectively. CONCLUSIONS: Nearly half of those who underwent MBS as adolescents screened positively for AUD, symptoms of alcohol-related harm, or alcohol-related problems 8 years post-MBS, highlighting the risk for alcohol use and AUD after MBS in adolescents. AUD evaluation and treatment should be integrated into routine long-term care for adolescents undergoing MBS.

Modes of failure of hip hemiarthroplasty for femoral neck fracture.

BACKGROUND: Hemiarthroplasty is a common treatment for displaced femoral neck fractures, but limited Canadian data are available about hemiarthroplasty failure. We evaluated the frequency and predictors of hemiarthroplasty failure in Manitoba. METHODS: In this retrospective multicentre province-wide study, billing and joint registry databases showed 4693 patients who had hemiarthroplasty for treatment of femoral neck fracture in Manitoba over an 11-year period (2005-2015), including 155 hips with subsequent reoperations (open or closed) for treatment of hemiarthroplasty failure. Hospital records were reviewed to identify modes of hemiarthroplasty failure, comorbidities and reoperations. Data were analyzed using χ2 test and Poisson and γ regression models. RESULTS: During our study period, 155 hips (154 patients [3%]) underwent 230 reoperations. Of these, 131 hips (85%) initially had an uncemented unipolar modular implant. Indications for first-time reoperation included periprosthetic femur fracture (49 hips [32%]), dislocation (45 hips [29%]), acetabular wear (28 hips [18%]) and infection (26 hips [17%]). There were 46 hips (30%) that had 2 or more reoperations. Reoperation for dislocation was associated with presence of dementia; acetabular wear was associated with absence of dementia. Time from hemiarthroplasty to reoperation was associated inversely with age at hemiarthroplasty, dislocation and dementia and was directly associated with acetabular wear. The risk of having 2 or more reoperations was associated independently with dislocation, infection, and alcohol abuse. CONCLUSION: Hemiarthroplasty for femoral neck fracture in Manitoba had a low frequency of failure. Risk factors for multiple reoperations included dislocation, infection and alcohol abuse.

Predictive Factors for Aortic Graft Infection: A Case-Control Study.

BACKGROUND: Graft infections are one of the most serious complications in vascular surgery, with high mortality rates. Few studies addressed risk factors associated with a higher susceptibility to infection. The aim of this study is to identify perioperative factors associated with aortic graft infections (AGI). METHODS: We designed a retrospective, case-control study from patients subjected to open aortic repair between 2013 and 2019. Cases of AGI were defined according to the management of aortic graft infection collaboration (MAGIC) criteria and matched to controls without proven infection. Demographics, hospital complications, and laboratory workups were assessed. Predictors of AGI were identified through univariate and multivariate analysis. RESULTS: Most graft infections occurred in a late period (n = 17; 85%), after a median interval of 13.5 months interquartile range (IQR 1.5-36). Gram-negative bacteria were most frequently isolated in infected grafts, namely Enterobacteriaceae (n = 12). Cases had significantly lower postoperative serum albumin levels (1.9 g/dL vs. 2.4 g/dL; P = 0.002). Alcohol abuse, malignancy, prolonged lengths of stay, wound infection and dehiscence, in-hospital infection, postoperative heart failure or bowel ischemia were significantly correlated to the onset of AGI. In the multivariate analysis, prolonged hospital stays odds ratio (OR 1.05; P = 0.03), malignancy (OR 5.82; P = 0.03) and alcohol abuse (OR 42.41; P = 0.002) maintained a significant association. CONCLUSIONS: The risk of AGI seems to be higher in patients with concurrent malignancy, alcohol abuse or prolonged hospital stays. Strategies to mitigate this complication in these patients are of utmost importance.

Neurosurgery in the Treatment of Alcohol Use Disorder: A Systematic Literature Review

Alcohol abuse has impacts on public health worldwide. Conservative treatment to achieve abstinence consists of detoxification combined with psychotherapy and the use of drugs, but it is estimated that only half of the individuals achieve long-term abstinence with the available treatments. In this sense, neurosurgery appears as a therapeutic proposal. The present study aimed to gather information about the circuitry related to alcohol use disorder (AUD), to describe possible surgical targets, and to establish whether a surgical approach could be a safe and effective treatment option. A systematic review of the literature was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. The 14 selected articles analyze ablative operations, deep brain stimulation (DBS), and a new procedure in which the patient is first submitted to repetitive transcranial magnetic stimulation to evaluate their response, and later an implant is surgically positioned on the evaluated target to obtain more lasting results. The most relevant outcomes were found when the anterior cingulate cortex (ACC) and the nucleus accumbens (NAcc) were used as targets, demonstrating a large reduction in alcohol intake and even its cessation. However, important side effects were observed, such as psychotic symptoms, right frontal venous infarction, seizures after implantation in the ACC and a hypomanic period after DBS in the NAcc, which could be reversed. Due to the lack of studies involving the surgical treatment of AUD, more clinical trials are needed to compare targets, to assess surgical techniques, and to estimate the safety of these techniques.

Alcohol Use Relapse Following Liver Transplantation for Alcoholic Liver Disease.

BACKGROUND Alcohol use disorders affect 10% of the European population. Alcohol-related liver disease (ALD) is the most common indication for liver transplantation in Slovakia. The aim of this study was to determine the proportion of patients with ALD who received a liver transplant who had alcohol relapsed, and the risk factors for alcohol relapse, as well as to compare clinical outcomes according to relapse. MATERIAL AND METHODS A retrospective study of consecutive patients with ALD, who underwent liver transplantation in a single transplant center between May 2008 and December 2017. We included adult patients who received a liver transplant due to ALD and excluded those who died <1 month after liver transplantation. We recorded demographic and clinical characteristics, graft injury, and overall mortality and compared them between relapsers and abstainers. RESULTS During the study period, we reviewed 196 cases of liver transplantation in 191 patients. We excluded 87 patients for non-ALD etiology and 15 patients by predefined criteria. The final analysis was carried out in 89 patients, mean aged 55 years; 24.7% were female. We diagnosed relapse in 23 patients (26%) with harmful drinking in 52% and occasional drinking in 48% of relapsers. The independent risk factors associated with relapse were: smoking (OR=5.92, P=0.006), loss of social status (OR=7.61, P=0.002), and time after liver transplantation (OR=1.0008, P=0.015). Graft injury was more frequent in relapsers with 2 independent risk factors: occasional drinking (OR=12.7, P=0.0005), and harmful drinking (OR=36.6, P<0.0001); overall survival was unaffected. CONCLUSIONS We found relapse to alcohol drinking in 26% of patients who received a liver transplant for ALD. Risk factors associated with alcohol drinking relapse were time, cigarette smoking, and loss of social status. Graft injury was more frequent in relapsers, but mortality was similar between relapsers and non-relapsers.

Preliminary findings in ablating the nucleus accumbens using stereotactic surgery for alleviating psychological dependence on alcohol.

We studied the effect of stereotactic surgery in cases of alcohol dependence. Twelve patients with a psychological dependence on alcohol (treated systematically with medication for detoxification 3-8 times in various rehabilitation centers before, but had relapsed within 2 weeks after withdrawal) were treated by ablating the nucleus accumbens (NA(C)) bilaterally using stereotactic surgery. The therapeutic effect and safety evaluation index of the surgery were analyzed. The timing of the conducted evaluations was preoperatively and in the sixth postoperative month. Currently, relapse has not occurred in 9 cases. Relapse occurred in 3 cases after surgery. The prevalence of relapse was 16.7% within 6 months, and 25% within 12 months. Non-specific complications of this type of surgery (e.g., intracranial hematoma, infection) were not observed. One case in 12 patients suffered dysosmia, but he recovered completely 4 months later after surgery. The full-scale intelligence quotient (FSIQ) and memory quotient (MQ) of these patients were significantly improved 6 months postoperatively compared with preoperatively. The severity of alcohol dependence scale and a scale measuring alcohol craving in these patients were significantly decreased. There were also significant changes over time in the Minnesota multiphasic personality inventory (MMPI) profile, suggesting a decrease in depression, irritability, and psychopathy. Ablating specified targets (NA(C)) using stereotactic surgery is a safe method to alleviate alcohol craving, reduce relapse rates and improve quality-of-life in patients with psychological dependence on alcohol.

Neohepatocytes from alcoholics and controls express hepatocyte markers and display reduced fibrogenic TGF-ß/Smad3 signaling: advantage for cell transplantation?

BACKGROUND: Liver transplantation is the only definitive treatment for end stage liver disease. Donor organ scarcity raises a growing interest in new therapeutic options. Recently, we have shown that injection of monocyte-derived NeoHepatocytes can increase survival in rats with extended liver resection. In order to apply this technology in humans with chronic liver diseases in an autologous setting, we generated NeoHepatocytes from patients with alcoholic liver disease and healthy controls and compared those to human hepatocytes. METHODS: We generated NeoHepatocytes from alcoholics with Child A and B cirrhosis and healthy controls. Hepatocytes marker expression and transforming growth factor (TGF)-beta signaling was investigated by RT-PCR, Western blot, immunofluorescent staining, and adenoviral reporter assays. Glucose and urea was measured photometrically. Phase I and II enzyme activities were measured using fluorogenic substrates. Neutral lipids were visualized by Oil Red O staining. RESULTS: There was no significant difference in generation and yield of NeoHepatocytes from alcoholics and controls. Hepatocyte markers, e.g., cytokeratin18 and alcohol dehydrogenase 1, increased significantly throughout differentiation. Glucose and urea production did not differ between alcoholics and controls and was comparable to human hepatocytes. During differentiation, phase I and II enzyme activities increased, however remained significantly lower than in human hepatocytes. Fat accumulation was induced by treatment with insulin, TGF-beta and ethanol only in differentiated cells and hepatocytes. TGF-beta signaling, via Smad transcription factors, critically required for progression of chronic liver disease, was comparable among the investigated cell types, merely expression of Smad1 and -3 was reduced (approximately 30 and approximately 60%) in monocytes, programmable cells of monocytic origin, and NeoHepatocytes. Subsequently, expression of TGF-beta regulated pro-fibrogenic genes, e.g., connective tissue growth factor and fibronectin was reduced. CONCLUSIONS: Generation of NeoHepatocytes from alcoholics, displaying several features of human hepatocytes, offers new perspectives for cell therapeutic approaches, as cells can be obtained repeatedly in a noninvasive manner. Furthermore, the autologous setting reduces the need for immunosuppressants, which may support recovery of patients which are declined for liver transplantation.

Increased cortisol response to surgery in patients with alcohol problems who developed postoperative confusion.

BACKGROUND: Patients with alcohol problems often develop postoperative confusion and have impaired cortisol, ACTH, and norepinephrine. However, the relationship between neuroendocrine responses to surgical stress and postoperative confusion remains unclear in patients with alcohol problems. METHODS: Plasma cortisol, ACTH, and norepinephrine concentrations during and after surgery in 30 patients with alcohol problems and 30 control patients who underwent lower abdominal surgery were measured before the induction of anesthesia, 15 and 60 min after skin incision, 60 min after the end of surgery, the next day, and the second day after the operation. RESULTS: Plasma cortisol concentrations (21.2 +/- 4.7 microg x dl) of patients with alcohol problems before anesthesia were significantly higher than 15.6 +/- 4.8 microg x dl(-1) of control patients. Plasma cortisol and ACTH responses to surgery in patients with alcohol problems were not significantly increased compared with preoperative values. The incidence of postoperative confusion was significantly higher in patients with alcohol problems than that of control patients (33% vs. 3%). Plasma cortisol concentrations (29.7 +/- 7.0, 31.2 +/- 6.6, 30.3 +/- 8.0, and 28.4 +/- 6.2 microg x dl(-1)) 15 and 60 min after the skin incision, 60 min after the end of surgery, and the next day after operation in postoperatively confused patients with alcohol problems were significantly higher than those of nonconfused patients with alcohol problems (23.0 +/- 5.8, 22.7 +/- 4.1, 22.4 +/- 7.2, and 21.9 +/- 5.5 microg x dl(-1)). CONCLUSION: The cortisol response to surgical stress increases in patients with alcohol problems who develop postoperative confusion, although cortisol response to surgical stress decreases in patients with alcohol problems without postoperative confusion.

Altered cell-mediated immunity and increased postoperative infection rate in long-term alcoholic patients.

BACKGROUND: Preoperative alteration of T cell-mediated immunity as well as an altered immune response to surgical stress were found in long-term alcoholic patients. The aim of this study was to evaluate perioperative T cell-mediated immune parameters as well as cytokine release from whole blood cells after lipopolysaccharide stimulation and its association with postoperative infections. METHODS: Fifty-four patients undergoing elective surgery of the aerodigestive tract were included in this prospective observational study. Long-term alcoholic patients (n = 31) were defined as having a daily ethanol consumption of at least 60 g and fulfilling the Diagnostic and Statistical Manual of Mental Disorders for either alcohol abuse or alcohol dependence. The nonalcoholic patients (n = 23) were defined as drinking less than 60 g ethanol/day. Blood samples to analyze the immune status were obtained on morning before surgery and on the morning of days 1, 3, and 5 after surgery. RESULTS: Basic patient characteristics did not differ between groups. Before surgery, the T helper 1:T helper 2 ratio (Th1: Th2) was significantly lower (P < 0.01), whereas plasma interleukin 1beta and lipopolysaccharide-stimulated interleukin 1ra from whole blood cells were increased in long-term alcoholic patients. After surgery, a significant suppression of the cytotoxic lymphocyte ratio (Tc1:Tc2), the interferon gamma:interleukin 10 ratio from lipopolysaccharide-stimulated whole blood cells, and a significant increase of plasma interleukin 10 was observed. Long-term alcoholics had more frequent postoperative infections compared with nonalcoholic patients (54%vs. 26%; P = 0.03). CONCLUSIONS: T helper cell-mediated immunity was significantly suppressed before surgery and possibly led to inadequate cytotoxic lymphocyte and whole blood cell response in long-term alcoholic patients after surgery. This altered cell-mediated immunity might have accounted for the increased infection rate in long-term alcoholic patients after surgery.

Preoperative evaluation of chronic alcoholics assessed for surgery of the upper digestive tract.

BACKGROUND: Alcoholics are at risk of developing major complications in the postoperative period. Adequate prophylactic treatment, as well as preoperative abstinence, can significantly decrease the rate of complications. However, the preoperative diagnosis of alcoholism is difficult to establish. The purpose of this study was to assess whether three preoperative visits, an alcohol-related questionnaire (CAGE), and the laboratory markers carbohydrate-deficient transferrin (CDT) and gamma-glutamyltransferase (GGT) would increase the rate of detection of chronic alcoholics. METHODS: The study included the Departments of ENT, Facial and Maxillofacial Surgery, and General Surgery of a university hospital; 705 male patients were assessed for tumor surgery of the upper digestive tract and were allocated to 5 different groups. All patients were seen three times, and five different strategies were used to detect chronic alcoholics. The gold standard was the diagnosis of alcohol misuse made by an experienced (blinded) investigator according to the DSM-III-R. The main outcome measurements were the detection rates of the different test strategies. RESULTS: By clinical routine alone, only 16% were detected during the first visit and 34% after three visits. If the CAGE questionnaire was added, sensitivity increased to 64%. The further addition of GGT or CDT led to 80 and 85% detections, respectively. A combination of all tests had a sensitivity of 91%. CONCLUSIONS: To detect more alcoholic patients at risk for major complications, patients should be seen more often, and additional diagnostic tools such as the CAGE, CDT, and GGT should be used before surgery.

Rapidly progressive liver injury and fatal alcoholic hepatitis occurring after liver transplantation in alcoholic patients.

Alcohol-related liver disease (ALD) is a common indication for orthotopic liver transplantation (OLT) in adults. Although return to 'heavy drinking' post-OLT is believed to be uncommon, the prevalence and severity of alcohol-related liver injury in such patients is not well characterized. We retrospectively reviewed the records of 68 adult patients who underwent OLT for ALD to determine the incidence of return to heavy drinking and to assess their clinical outcome. Follow-up ranged from 8-99 months (mean 42) post-OLT; 54 patients were followed for > or = 12 months. Ten patients (15%) had evidence of coexisting viral hepatitis (hepatitis C in 9 and hepatitis B in 1) before OLT. Six of 68 patients (8%) returned to heavy drinking post-OLT, and three of those died of alcoholic hepatitis at nine months, 2.5 and 3.5 years after OLT. In two of these three patients, premortem liver biopsy showed histologic features of alcoholic hepatitis in addition to bridging fibrosis or cirrhosis. None of the three patients who died of ALD had coexisting viral hepatitis. Of the 57 patients surviving for > or = 3 months post-OLT, 4 of 8 patients (50%) with steatosis and Mallory bodies in their native livers returned to heavy drinking compared to only 2/49 (4%) without these histologic findings (P<0.05). In conclusion, the incidence of heavy drinking post-OLT was uncommon, however, it was associated with fatal alcoholic hepatitis in 50% of patients. Rapidly progressive alcohol-related liver injury was seen even in the absence of coexisting viral hepatitis. The presence of steatosis and Mallory bodies in the native liver, which suggests recent or ongoing alcohol-related liver injury, predicted a return to heavy drinking post-OLT.

Distúrbios psiquiátricos relacionados ao álcool associados a diagnósticos de clínica médica e/ou intervençöes cirúrgicas, atendidos num hospital geral / Psychiatric disorders related to alcohol and associated to general clinical medical diagnoses and/or surgical interventions of patients admitted in a general hospital

Através de um inquérito epidemiológico, buscou-se detectar as co-morbidades dos diagnósticos psiquiátricos relacionados ao álcool. Para tanto, investigou-se os atendimentos num Hospital de Urgências Médicas no Setor de Psiquiatria, no período de 1988 a 1991, tendo por objetivo identificar quais as doenças clínicas e outros incidentes que acometem a populaçäo referida. Fizeram parte do levantamento os diagnósticos relacionados ao álcool, conforme CID 9 (291; 303 e 305.0) e os associados à näo pertencentes à psiquiatria. Evidenciou-se no período, 1835 casos com diagnósticos relacionados ao álcool e destes 487 (26,5 por cento) se referiram aos grupos 291-303-305.0, associados à outros näo psiquiátricos. Desse total a maior frequência de casos ocorreu nos grupos 340-349 (Outros transtornos do SNC) e 800-859 (Lesöes e complicaçöes traumáticas) com 80 (16,4 por cento) atendimentos, respectivamente. Observando-se os dados por ano, constata-se que dos diagnósticos relacionados ao álcool (com diagnósticos clínicos associados) o 303 (Síndrome de Dependência Alcoólica) foi que teve maior número de atendimento com 326 (67 por cento) casos, seguido de 291 (Psicose Alcoólica) com 117 (24 por cento) e 305.0 (Alcool) com 44 (9 por cento). No período, tanto o diagnóstico psiquiátrico 303 como o 291, apareceram mais frequentemente associados ao grupo de diagnósticos clínicos 340-349, com 55 (11,2 por cento) e 12 (2.4 por cento) casos, respectivamente e o 305.0 teve o grupo 800-859 com 10 (2 por cento) casos, como o mais frequente.

[Hemorrhage through Wirsung's duct: rare form of upper gastrointestinal hemorrhage. A case report]. / Hémorragie par le canal de Wirsung: forme rare d'hémorragie digestive haute. A propos d'une observation.

The case of a 41-year-old alcoholic patient who presented with massive upper gastrointestinal bleeding is reported. The diagnosis was established rapidly by endoscopy which revealed bleeding through the papilla of Vater. Selective angiography of the superior mesenteric artery opacified the pancreatic duct as well as the duodenum. CT scan showed signs of chronic pancreatitis. Because of the recurrence of bleeding and shock, an urgent operation was necessary and a Whipple procedure was performed. Recovery was complete. The clinical presentation, the etiology, the diagnostic modalities and the treatment of this particular condition are discussed. Usually, hemorrhage through the pancreatic duct presents as repeated episodes of upper gastrointestinal bleeding with no source found at endoscopy. The presence of chronic pancreatitis or of epigastric pain during bleeding should suggest the diagnosis. Upper gastrointestinal endoscopy and angiography are the principal diagnostic tools.
