Safety and outcomes of hip and knee replacement surgery in liver transplant recipients. World J Orthop 2023; 14:784-790. [DOI: 10.5312/wjo.v14.i11.784] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 09/13/2023] [Accepted: 10/23/2023] [Indexed: 11/16/2023] Open
Abstract
BACKGROUND Liver transplant (LT) is becoming increasingly common with improved life expectancy. Joint replacement is usually a safe procedure; however, its safety in LT recipients remains understudied.
AIM To evaluate the mortality, outcome, and 90-d readmission rate in LT patients undergoing hip and knee replacement surgery.
METHODS Patients with history of LT who underwent hip and knee replacement surgery between 2016 and 2019 were identified using the National Readmission Database.
RESULTS A total of 5046119 hip and knee replacement surgeries were identified. 3219 patients had prior LT. Mean age of patients with no history of LT was 67.51 [95% confidence interval (CI): 67.44-67.58], while it was 64.05 (95%CI: 63.55-64.54) in patients with LT. Patients with history of LT were more likely to have prolonged length of hospital stay (17.1% vs 8.4%, P < 0.001). The mortality rate for patients with no history of LT was 0.22%, while it was 0.24% for patients with LT (P = 0.792). Patients with history of LT were more likely to have re-admissions within 90 d of initial hospitalization: 11.4% as compared to 6.2% in patients without history of LT (P < 0.001). The mortality rate between both groups during readmission was not statistically different (1.9% vs 2%, P = 0.871) respectively.
CONCLUSION Hip and knee replacements in patients with history of LT are not associated with increased mortality; increased re-admissions were more frequent in this cohort of patients. Chronic kidney disease and congestive heart failure appear to predict higher risk of readmission.

Incidence and Cross-Continents Differences in Endoscopic Retrograde Cholangiopancreatography Outcomes Among Patients With Cirrhosis: A Systematic Review and Meta-Analysis. Gastroenterology Res 2023; 16:105-117. [PMID: 37187552 PMCID: PMC10181340 DOI: 10.14740/gr1610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Accepted: 03/28/2023] [Indexed: 05/17/2023] Open
Abstract
Background There are conflicting data on the frequency and variability of endoscopic retrograde cholangiopancreatography (ERCP) outcomes in patients with cirrhosis. Our aim was to systematically review the literature on the incidence of post-ERCP adverse events in cirrhotic patients and to examine the differences across continents. Methods We searched PubMed/MEDLINE, EMBASE, Scopus, and Cochrane databases to identify studies reporting adverse events after ERCP in patients with cirrhosis from conception to September 30, 2022. The random effects model was used to calculate odds ratios (ORs), mean differences (MDs), and confidence intervals (CIs). A P value < 0.05 was considered statistically significant. Heterogeneity was assessed using the Cochrane Q-statistic (I2). Results Twenty-one studies that included 2,576 cirrhotic patients and 3,729 individual ERCPs were analyzed. The pooled overall rate of adverse events after ERCP in patients with cirrhosis was 16.98% (95% CI: 13.06-21.29%, P < 0.001, I2 = 86.55%). ERCPs performed in Asia had the highest ERCP adverse events with an overall complication rate of 19.90%, while the lowest overall adverse events were in North America at 13.04%. The pooled post-ERCP bleeding, pancreatitis, cholangitis and perforation were 5.10% (95% CI: 3.33-7.19%, P < 0.001, I2 = 76.79%), 3.21% (95% CI: 2.20-5.36%, P = 0.03, I2 = 42.25%), 3.02% (95% CI: 1.19-5.52%, P < 0.001, I2 = 87.11%), and 0.12% (95% CI: 0.00 - 0.45, P = 0.26, I2 = 15.76%), respectively. The pooled post-ERCP mortality rate was 0.22% (95% CI: 0.00-0.85%, P = 0.01, I2 = 51.86%). Conclusions This meta-analysis shows that the overall complication rates after ERCP, bleeding, pancreatitis, and cholangitis are high in patients with cirrhosis. Because cirrhotic patients are more likely to have post-ERCP complications, with significant cross-continent variations, the risks and benefits of ERCP in this patient population should be carefully considered.

Transjugular Intrahepatic Portosystemic Shunt With or Without Gastroesophageal Variceal Embolization for the Prevention of Variceal Rebleeding: A Systematic Review and Meta-Analysis. Gastroenterology Res 2023; 16:68-78. [PMID: 37187555 PMCID: PMC10181335 DOI: 10.14740/gr1618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 04/14/2023] [Indexed: 05/17/2023] Open
Abstract
Background The role of variceal embolization (VE) during transjugular intrahepatic portosystemic shunt (TIPS) creation for preventing gastroesophageal variceal rebleeding remains controversial. Therefore, we performed a meta-analysis to compare the incidence of variceal rebleeding, shunt dysfunction, encephalopathy, and death between patients treated with TIPS alone and those treated with TIPS in combination with VE. Methods We performed a literature search using PubMed, EMBASE, Scopus, and Cochrane databases for all studies comparing the incidence of complications between TIPS alone and TIPS with VE. The primary outcome was variceal rebleeding. Secondary outcomes include shunt dysfunction, encephalopathy, and death. Subgroup analysis was performed based on the type of stent (covered vs. bare metal). The random-effects model was used to calculate the relative risk (RR) with the corresponding 95% confidence intervals (CIs) of outcome. A P value < 0.05 was considered statistically significant. Results Eleven studies with a total of 1,075 patients were included (597: TIPS alone and 478: TIPS plus VE). Compared to the TIPS alone, the TIPS with VE had a significantly lower incidence of variceal rebleeding (RR: 0.59, 95% CI: 0.43 - 0.81, P = 0.001). Subgroup analysis revealed similar results in covered stents (RR: 0.56, 95% CI: 0.36 - 0.86, P = 0.008) but there was no significant difference between the two groups in the subgroup analysis of bare stents and combined stents. There was no significant difference in the risk of encephalopathy (RR: 0.84, 95% CI: 0.66 - 1.06, P = 0.13), shunt dysfunction (RR: 0.88, 95% CI: 0.64 - 1.19, P = 0.40), and death (RR: 0.87, 95% CI: 0.65 - 1.17, P = 0.34). There were similarly no differences in these secondary outcomes between groups when stratified according to type of stent. Conclusions Adding VE to TIPS reduced the incidence of variceal rebleeding in patients with cirrhosis. However, the benefit was observed with covered stents only. Further large-scale randomized controlled trials are warranted to validate our findings.

Hospitalizations for alcoholic liver disease during the COVID-19 pandemic increased more for women, especially young women, compared to men. World J Hepatol 2023; 15:282-288. [PMID: 36926241 PMCID: PMC10011902 DOI: 10.4254/wjh.v15.i2.282] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 01/15/2023] [Accepted: 02/09/2023] [Indexed: 02/24/2023] Open
Abstract
BACKGROUND Alcoholic liver disease (ALD) remains one of the major indications for liver transplantation in the United States and continues to place a burden on the national healthcare system. There is evidence of increased alcohol consumption during the coronavirus disease 2019 (COVID-19) pandemic, and the effect of this on the already burdened health systems remains unknown.
AIM To assess the trends for ALD admissions during the COVID-19 pandemic, and compare it to a similar pre-pandemic period.
METHODS This retrospective study analyzed all admissions at a tertiary health care system, which includes four regional hospitals. ALD admissions were identified by querying a multi-hospital health system’s electronic database using ICD-10 codes. ALD admissions were compared for two one-year periods; pre-COVID-19 from April 2019 to March 2020, and during-COVID-19 from April 2020 to March 2021. Data were analyzed using a Poisson regression model and admission rates were compared using the annual quarterly average for the two time periods, with stratification by age and gender. Percent increase or decrease in admissions from the Poisson regression model were reported as incident rate ratios.
RESULTS One thousand three hundred and seventy-eight admissions for ALD were included. 80.7% were Caucasian, and 34.3% were female. An increase in the number of admissions for ALD during the COVID-19 pandemic was detected. Among women, a sharp rise (33%) was noted in those below the age of 50 years, and an increase of 22% in those above 50 years. Among men, an increase of 24% was seen for those below 50 years, and a 24% decrease in those above 50 years.
CONCLUSION The COVID-19 pandemic has had widespread implications, and an increase in ALD admissions is just one of them. However, given that women are often prone to rapid progression of ALD, this finding has important preventive health implications.

High prevalence of non-alcoholic fatty liver disease in patients with inflammatory bowel disease receiving anti-tumor necrosis factor therapy. Ann Gastroenterol 2019; 32:463-468. [PMID: 31474792 PMCID: PMC6686093 DOI: 10.20524/aog.2019.0405] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2019] [Accepted: 06/25/2019] [Indexed: 02/07/2023] Open
Abstract
Background: Non-alcoholic fatty liver disease (NAFLD) is common in patients with inflammatory bowel disease (IBD). This study evaluated the prevalence of NAFLD and the associated risk factors among IBD patients who received anti-tumor necrosis factor (TNF) therapy. Methods: Adult IBD patients receiving anti-TNF therapy (infliximab, adalimumab, certolizumab, golimumab) were enrolled. Hepatic steatosis was assessed by abdominal ultrasound. Patients with a history of excessive alcohol or recent steroid use were excluded. Univariate and multivariate analysis were performed. Results: Eighty patients, 55% male, mean age 42±15 years, were enrolled. The sonographic prevalence of NAFLD was 54% (43/80), significantly higher than the general prevalence in the US adult population (30%) (P<0.0001). NAFLD patients had a significantly higher proportion of males, as well as greater body weight and body mass index, compared to non-NAFLD. The Crohns disease activity index (CDAI) was significantly higher among patients with NAFLD. Multivariate analysis demonstrated that a higher CDAI was independently associated with NAFLD, with an odds ratio of 1.6 (95% confidence interval 1.05-2.44; P=0.03). Conclusions: The presence of IBD is strongly associated with NAFLD. We identified a high prevalence of NAFLD among IBD patients receiving anti-TNF. CDAI was independently associated with hepatic steatosis. Further studies are still needed to evaluate the pathophysiology of NAFLD development and disease progression among IBD populations.

Abstract
Background Non-alcoholic fatty liver disease (NAFLD) is common in patients with inflammatory bowel disease (IBD). The purpose of this study was to further examine the prevalence of NAFLD in IBD patients. Methods We retrospectively reviewed the medical records of IBD patients who visited the emergency department because of abdominal pain between January 2009 and December 2014. These were compared with a group of 70 controls without IBD, matched for age and body mass index (BMI). Computed tomography data were analyzed for the presence or absence of hepatic steatosis. Patient with recent steroid or excessive alcohol use were excluded. Univariate and multivariate analyses were performed. Results NAFLD prevalence was 44% (31/70) in the IBD group vs. 16% (11/70) in controls (P<0.001). There was no significant difference between the 2 groups in age, sex distribution, BMI, presence of diabetes, or levels of serum transaminases, serum albumin or platelets. In multivariate analysis, the presence of IBD was independently associated with NAFLD (odds ratio 4.53, 95% confidence interval 2.00-10.26; P=0.002). Conclusions The presence of IBD is strongly and independently associated with NAFLD. Systemic inflammation and alteration of the intestinal microbiome have been proposed as mechanisms, but further studies are needed to better elucidate the pathophysiology.

Increased intrathoracic and hepatic visceral adipose tissue independently correlates with coronary artery calcification in asymptomatic patients. J Nucl Cardiol 2014; 21:880-9.

Abstract
BACKGROUND Visceral adipose tissue (VAT) is associated with cardiac events, but it is not clear which, if any of the various measures of VAT independently correlate with coronary artery disease (CAD). METHODS We studied 400 patients undergoing computed tomography to determine coronary artery calcium (CAC) score. VAT was measured in the form of epicardial adipose tissue (EAT) volume and thickness, intrathoracic adipose tissue volume (ITAV), and hepatic steatosis. RESULTS Of the 400 subjects, the average CAC score was 112.2 ± 389.3. When each measure of VAT (EAT volume and thickness, ITAV, hepatic steatosis) was added to the traditional model (they were independently associated with greater risk of CAC score ≥100 AU as measured by IDI/NRI (P < .05). On univariable logistic regression analysis, each of the 4 measures of VAT showed association with greater risk of a CAC score of ≥100 AU (OR > 1). CONCLUSIONS Each measure of VAT is a strong correlate of CAC score ≥100 AU in asymptomatic subjects-these VAT assessments correlate more significantly than do traditional CAD risk factors. This incremental power in the predictive models is likely the result of measurement of a fundamental expression of the metabolic syndrome and consequent proatherogenic derangements.

Abstract
OBJECTIVE To determine the association of coronary artery calcification with hepatic steatosis in asymptomatic volunteers. PATIENTS AND METHODS The study group comprised 400 asymptomatic volunteers, enrolled from April 1, 2011, to September 30, 2012, without known coronary artery disease who were self-referred for screening noncontrast computed tomography to determine coronary calcium score (CCS). Computed tomographic images were used to determine the presence of hepatic steatosis. An a priori model was created to predict a CCS of 100 Agatston units (AU) or higher on the basis of Framingham risk factors, diabetes mellitus, and metabolic syndrome. Hepatic steatosis was then added to this model. Computation of the odds ratio (OR) for hepatic steatosis predicting a CCS of 100 AU or higher was performed. Finally, the OR for a CCS of 100 AU or higher being associated with hepatic steatosis was calculated. RESULTS When hepatic steatosis was added to traditional coronary risk factors, it was independently associated with a CCS of 100 AU or higher (OR, 2.85). This was greater than the OR of Framingham factors, diabetes mellitus, or metabolic syndrome. A CCS of 100 AU or higher was independently associated with an increased risk for hepatic steatosis (OR, 2.4). This OR was higher than traditional hepatic steatosis risk factors or metabolic syndrome. CONCLUSION Hepatic steatosis is a strong independent predictor of a CCS of 100 AU or higher in asymptomatic patients. It is associated with an increased risk of coronary artery disease beyond that expected from traditional coronary risk factors and/or metabolic syndrome. Additional studies are needed to clarify the role of hepatic steatosis as a possible independent risk factor for the development of coronary artery disease.

Abstract
Data on the development of cardiovascular disease in professional football players are conflicting. Studies have documented a higher prevalence of obesity, lower high-density lipoprotein cholesterol levels, increased left ventricular and left atrial size, and higher prevalence of metabolic syndrome in former professional football linemen compared with nonlinemen. It has been suggested that former National Football League players are at risk for early cardiovascular disease and premature death. A print media report in 2006 indicated an increased prevalence of cardiovascular disease and early mortality in professional football players compared with professional baseball players. However, there has been little scientific evaluation of cardiovascular risk factors in professional baseball players. Our data suggest that there is increased cardiovascular disease risk in football players, but this is limited to heavier linemen. In preliminary studies, baseball players do not appear to demonstrate the same increased risk. However, caution should be used in the interpretation of increased cardiovascular disease risk, as it does not necessarily translate into early increased mortality.

Abstract
In 2006, a newspaper report indicated an increased prevalence of cardiovascular disease and early mortality in retired professional football players compared to professional baseball players. This study included 69 professional football players from a 2008 National Football League training camp and 155 professional baseball players from an American League 2009 spring training site who volunteered to participate in a study of cardiovascular and metabolic risk factors. The prevalence of body mass index > or =30 kg/m(2), waist circumference > or =100 cm, waist/height ratio >0.5, blood pressure > or =130/85 mm Hg, triglycerides > or =150 mg/dl, triglycerides/high-density lipoprotein cholesterol ratio >3.5, high-density lipoprotein cholesterol < or =40 mg/dl, and alanine aminotransferase > or =40 IU/L was determined in baseball players and compared to measurements obtained in a matched cohort from the National Health and Nutrition Examination Survey (NHANES), professional football players, and linemen and nonlinemen subsets. In conclusion, professional baseball players had favorable cardiovascular parameters, with the exception of an increased prevalence of hypertension, compared to the reference population, and professional baseball players had decreased measures of obesity, hyperglycemia, and the cardiometabolic syndrome compared to professional football lineman.

Abstract
Present data about the increased incidence of early cardiovascular disease and mortality in National Football League (NFL) players is conflicting. These findings are particularly concerning given the escalating weight of current football players at the high school, collegiate, and professional levels. Recent studies have confirmed that heavier former NFL linemen have an increased prevalence of cardiovascular disease compared with an age- and sex-matched reference population. Former linemen had a higher prevalence of obesity, lower high-density lipoprotein cholesterol, increased left ventricular mass and left atrial area, and the metabolic syndrome, compared with nonlinemen. There have been sparse data on the cardiovascular health of current players. A recent analysis of one team demonstrated that the cardiometabolic syndrome and its individual components were significantly more common in linemen versus nonlinemen. Because current heavier NFL players already have evidence of the cardiometabolic syndrome and its individual markers, careful medical evaluation of former and active players is warranted to reduce their risks. This medically and ethically indicated intervention, however, might limit interpretation of future longitudinal studies designed to assess mortality endpoints.

Abstract
Media reports suggested an increased prevalence of cardiovascular disease and premature death in former National Football League (NFL) players. The prevalence of cardiometabolic syndrome was determined in current active NFL players. The presence of cardiometabolic syndrome was defined as > or =3 of (1) blood pressure > or =130/85 mm Hg, (2) fasting glucose > or =100 mg/dl, (3) triglycerides > or =150 mg/dl, (4) waist circumference > or =100 cm, and (5) high-density lipoprotein cholesterol < or =40 mg/dl. Sixty-nine of 91 players (76%) from 1 NFL team were studied before the 2008 preseason training camp. Cardiometabolic syndrome markers, body mass index (BMI), waist-height ratio, and triglycerides/high-density lipoprotein cholesterol ratio were compared between 69 players and an age- and gender-matched reference population from NHANES (1999 to 2002) and by player position of linemen versus nonlinemen. Blood pressure > or =130/85 mm Hg, glucose > or =100 mg/dl, and BMI > or =30 kg/m(2) were significantly more prevalent in the 69 players than the NHANES cohort (28% vs 17%, p = 0.032; 19% vs 7%, p = 0.002; and 51% vs 21%, p <0.001, respectively), although cardiometabolic syndrome prevalence was similar in both groups. However, cardiometabolic syndrome prevalence, BMI > or =30 kg/m(2), and waist-height ratio >0.5 were significantly more common in the linemen versus the nonlinemen subgroup (22% vs 0%, p = 0.004; 100% vs 32%, p <0.001, and 95% vs 36%, p <0.001 respectively). In conclusion, cardiometabolic syndrome and its individual components were noted in current NFL players, particularly linemen.

Abstract
OBJECTIVE We designed a prospective study to determine the frequency of retroperitoneal air after endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy. We sought to elucidate the relationship of retroperitoneal air with endoscopic maneuvers, clinical findings, the length of sphincterotomy, and the time spent during the procedure. We also endeavored to determine the importance of retroperitoneal air and its most appropriate clinical management. METHODS Twenty-one consecutive patients who had undergone ERCP with sphincterotomy had abdominal computed tomography (CT) examinations within 24 h after completion of the procedure. The CT findings were unknown to the clinicians, and none of the patients received postprocedural antibiotics. RESULTS Six (29%) of 21 patients exhibited CT findings of retroperitoneal air. All six patients had uneventful postprocedural courses, and none had abnormal clinical signs or symptoms. The occurrence of retroperitoneal air was not influenced by the presence of hyperamylasemia, the duration of the procedure, or the length of the sphincterotomy. CONCLUSIONS Retroperitoneal air is not an uncommon finding after ERCP with sphincterotomy. Moreover, the finding of retroperitoneal air in the absence of physical findings, is not a cause for alarm and does not require surgical intervention.

Abstract
The clinicopathologic features and natural history of primary sclerosing cholangitis were reviewed in 53 patients followed at the Yale Liver Center during the past 30 yr. At presentation, the mean age of patients was 46 yr, and the male to female ratio was 1.4:1. Biliary sclerosis was limited to the intrahepatic ductal system in 21% of the patients. Fifty-three percent of the patients had mild disease without portal hypertension at presentation, and 25% had no symptoms attributable to their liver disease. Long-term follow-up was available for 42 patients and averaged 56 mo. Over this period, 16 patients remained mildly symptomatic, and 11 were asymptomatic. Survival was calculated by a Kaplan-Meier life-table analysis and demonstrated that 75% of the patients were alive 9 yr after the diagnosis of primary sclerosing cholangitis. A multivariate analysis of clinical features revealed that hepatomegaly and a serum bilirubin level greater than 1.5 mg/dl at the onset of disease were independent discriminators of a poor prognosis. Patients referred to this university medical center displayed different clinical characteristics than previously reported in primary sclerosing cholangitis. A higher percentage were older, female, and asymptomatic, and more had disease limited to the intrahepatic ductal system. Survival was also considerably improved in this group of patients and suggests that the long-term prognosis for patients with primary sclerosing cholangitis may be considerably better than previously believed.

Abstract
In vivo 31phosphorus nuclear magnetic resonance spectroscopy was used to measure the hepatic metabolic state in various groups of rats given ethanol, a control liquid diet or a solid chow diet. The use of selective presaturation pulses applied to the broad phosphorus resonances of immobile phospholipids permitted reliable determination of ATP/ADP ratios by quantitation of the ATP-beta and ATP-gamma peak areas. ATP/ADP ratios were depressed by both techniques in rats chronically ingesting ethanol compared to pair-fed animals consuming the control liquid diet. These differences were observed regardless of whether ethanol feeding was continued up to the time of investigation or whether it was discontinued for 24 hr prior to study. Acute alcohol administration in chow-fed rats, not previously ingesting ethanol, did not lower hepatic ATP/ADP ratios by either methodology. In all cases, liver ATP/ADP ratios assessed by 31phosphorus nuclear magnetic resonance spectroscopy were higher than those measured by high-performance liquid chromatography. However, parallel decreases in hepatic ATP/ADP ratios were observed with chronic ethanol consumption by both 31phosphorus nuclear magnetic resonance spectroscopy and the biochemical method, confirming the utility of in vivo 31phosphorus nuclear magnetic resonance spectroscopy for assessment of the hepatic bioenergetic status. The difference in absolute ATP/ADP ratios by the two methods may to some degree be explained by binding effects of ADP with proteins or mitochondrial membranes, rendering it partially invisible to nuclear magnetic resonance or alternatively, by breakdown of high energy phosphate bonds with freeze clamp extraction.

Abstract
A 51-year-old woman with malignant ascites secondary to hepatocellular carcinoma had a peritoneovenous (LeVeen) shunt inserted with effective control of ascites and amelioration of symptoms. The results of 12 recent series evaluating the efficacy of peritoneovenous shunts in the treatment of 198 patients with malignant ascites were reviewed. Peritoneovenous shunts effectively controlled malignant ascites in 77% of patients. Complications occurred in 25%, although the majority of these were related to shunt occlusion and transient congestive heart failure.

Abstract
The flexible sigmoidoscope is clearly the best available screening tool for colorectal cancer. It is superior to rigid sigmoidoscopy in that the flexible scope can examine longer lengths of bowel and yields a larger number of pathologic findings. The majority of colon cancers lie beyond the view of the rigid scope, which detects only about 30% of all malignant lesions.

Hepatocellular carcinoma: an unusual course with hyperthyroidism and inappropriate thyroid-stimulating hormone production. Gastroenterology 1985; 88:181-4.

Abstract
A 61-yr-old woman was found to have multicentric hepatocellular carcinoma associated with clinical hyperthyroidism. Marked elevations in serum thyroid-stimulating hormone, T4, T3, and free T4 were documented. These values increased with tumor progression. It is postulated that this patient's hepatoma produced a substance stimulating thyroid-stimulating hormone synthesis and secretion with resultant inappropriate thyroid-stimulating hormone production and thyrotoxicosis. This unusual association of hepatocellular carcinoma with clinical and biochemical evidence of hyperthyroidism and inappropriate thyroid-stimulating hormone production has not been previously reported.

Abstract
A 31-year-old white man with suspected aspiration pneumonia complicated by multiple pulmonary abscesses had profound neutropenia during a course of high-dose benzylpenicillin therapy for suspected bacterial endocarditis. Antigranulocyte antibodies were identified in the patient's serum. Leukopenia is an uncommon but potentially serious complication of therapy with this drug. We recommend weekly monitoring of blood counts during prolonged therapy with any beta-lactam antibiotic.
