Nutritional status and clinical outcomes among institutionalized elderly Chinese in Taiwan.

Nutrition is an important issue in institutional care, and is related to clinical outcomes in many aspects. Although Taiwan is marching to an aged society, related studies were lacking. Elderly residents in two long-term care facilities (LTCF) were enrolled for study. Nutritional status including anthropometric measurements and laboratory examinations was assessed every 3 months for 12 months. Age, sex-matched community-dwelling elderly participating in the annual health check-up was randomly selected as the control subjects. In total, 66 subjects in LTCF and 870 age, sex-matched community-dwelling elderly were enrolled. Body mass index, serum levels of albumin, and total cholesterol were significantly poorer in LTCF residents than the community-dwelling elderly. Triceps skinfold thickness, hemoglobin, serum albumin, and total cholesterol were progressively deteriorated among the institutionalized elderly during the 6-month follow-up. Thirteen subjects of the study group had been hospitalized during the follow-up. Body mass index, triceps skinfold thickness, mid-arm circumference, serum albumin at screening were significantly poorer and unintentional weight loss within 6 months was significantly greater in subjects who had been hospitalized. By using multivariate logistic regression model, only weight loss >5% within 6-month follow-up was the significant independent predictive factors to hospitalization. In conclusion, nutritional status of institutionalized elderly Chinese was significantly poorer than the community-dwelling elderly. Nutritional markers were progressively deteriorated in LTCF residents during the follow-up period. Unintentional weight loss >5% within 6 months was the only significantly independent predictive factor for hospitalization among the institutionalized elderly Chinese.

Hyponatremia among the institutionalized elderly in 2 long-term care facilities in Taipei.

BACKGROUND: Hyponatremia is common in the institutionalized elderly, and syndrome of inappropriate antidiuretic hormone secretion was deemed the most important etiologic factor. The purpose of this study was to evaluate the prevalence and etiologic factors of hyponatremia among institutionalized elderly and to explore its association with nutritional status. METHODS: Subjects in 2 private long-term care facilities (LTCFs) participated in this study. Periodic nutritional evaluations, including anthropometric measurements and serial laboratory examinations, were performed every 6 months. When hyponatremia was identified, serum osmolality, serum levels of cortisol, thyrotropin, antidiuretic hormone, urine osmolality, and electrolyte profile were done instantly. Water loading tests were performed for subjects with euvolemic, hypo-osmolar hyponatremia. Nutritional status (i.e. hemoglobin, serum albumin, serum total cholesterol, body mass index [BMI], and mean body weight loss within 6 months) was compared between hyponatremic and normonatremic subjects during hyponatremic episodes and at follow-up (6 months later). RESULTS: In total, 67 (mean age = 77.2 +/- 8.8 years, M/F = 45/22) LTCF residents were enrolled. The prevalence of hyponatremia was 31.3% (21/67) during the 6-month period, and 62.5% of these cases were related to reset osmostat. In addition, BMI was similar between hyponatremic and normonatremic subjects during hyponatremic episodes (19.1 +/- 3.2 vs 20.5 +/- 4.0 kg/m2, p = 0.16), but became significantly lower in hyponatremic subjects 6 months later (18.5 +/- 3.2 vs 20.8 +/- 4.2 kg/m2, p = 0.027). However, the mean body weight loss during the 6-month follow-up was similar (3.0% vs 0.8%, p = 0.25). Furthermore, hemoglobin and serum levels of albumin were similar between groups during hyponatremic episodes and at follow-ups, but serum levels of total cholesterol were significantly lower in hyponatremic subjects on both occasions (166.9 +/- 30.5 vs 190.2 +/- 38.2 mg/dL, p = 0.016 during hyponatremic episodes and 153.6 +/- 29.4 vs 182.8 +/- 35.5 mg/dL, p = 0.003 at follow-up). CONCLUSION: About a third of LTC-dwelling elderly would experience hyponatremia during the 6-month period, and 62.5% of them were due to reset osmostat. The relationship between hyponatremia and undernutrition deserves further investigation.

Asymptomatic bacteriuria among the institutionalized elderly.

BACKGROUND: Urinary tract infections (UTI) are the most common type of infection among residents of long-term care facilities (LTCFs). The presence of asymptomatic bacteriuria among LTCF residents brings challenges to onsite health professionals. The aim of this study was to explore the prevalence and related factors of aymptomatic bacteriuria among the institutionalized elderly in Taiwan. METHODS: In 2002, residents of 2 private LTCFs participated in this study. History taking, anthropometric measurements, and urine and blood samplings were performed by experienced research staff. Urine bacterial culture was performed by a standard procedure; subjects with symptoms indicating UTI were excluded. Repeated urine bacterial culture was performed 1 week after screening tests. Bacteriuria was defined as 1 or more organisms isolated from 2 consecutive urine specimens (> or =10(5) CFU [colony-forming units]/mL). Asymptomatic bacteriuria was defined as identical microorganisms isolated from 2 urine culture specimens taken at 1-week intervals from a subject who was free of UTI symptoms. The presence of asymptomatic bacteriuria and its related factors, such as age, sex, nutritional status, and long-term placement of urinary catheter, were evaluated. RESULTS: A total of 64 institutionalized Chinese elderly (mean age, 76.2 +/- 9.1 years; male:female, 48:16) were collected. The prevalence of asymptomatic bacteriuria was 57.8% (37/64), and was not associated with age, sex, functional status, long-term foley catheter, or previous UTI history. The most commonly isolated organisms were Escherichia coli (29.7%), Klebsiella pneumoniae (21.6%), Providentia stuartii (16.2%), and Pseudomonas aeruginosa (13.5%). Moreover, 21.6% of them showed multiple organisms. Nutritional status (body mass index, serum levels of albumin, total cholesterol, total lymphocyte count, and hemoglobin) was similar between subjects with or without bacteriuria (p > 0.05). CONCLUSION: Asymptomatic bacteriuria is common among Chinese residents in LTCFs. Escherichia coil was the most commonly cultured bacterium. Presence of asymptomatic bacteriuria was not associated with age, sex, functional status, catheter indwelling, previous history of UTI, or nutritional status of residents in LTCFs.

Association of insulin resistance and hematologic parameters: study of a middle-aged and elderly Chinese population in Taiwan.

BACKGROUND: Chronic inflammation is a common feature related to changes in hematologic parameters in insulin resistance. The aims of this study were to explore the relationship between hematologic parameters and insulin resistance, and to establish a gerontologic profile for following studies. METHODS: Residents aged over 40 years in 3 major townships in I-Lan County participating in the Adult Health Examination were invited for the study. Diagnosis of diabetes mellitus (DM) was done according to American Diabetes Association criteria. Insulin resistance was measured by homeostasis model assessment (HOMA-IR), and subjects with the highest tertile of HOMA-IR were defined as being insulin resistant. Hematologic parameters including white blood cell (WBC) count, red blood cell (RBC) count, hemoglobin, and platelet count were measured for comparisons. RESULTS: A total of 857 subjects (mean age, 64.6 +/- 11.2 years; male/female, 373/484) participated in this study. Their mean body mass index (BMI) was 24.5 +/- 3.7 kg/m2, and 42.4% of them were obese and 21.8% were overweight. The overall prevalence of DM was 15.4% (7.7% were previously diagnosed and 7.7% were newly diagnosed), and impaired fasting glucose was 7.2%. Trend analyses confirmed that age, BMI, HOMA-IR, WBC and platelet counts were significantly increased as glycemic metabolism exacerbated (p = 0.007, < 0.001, < 0.001, < 0.001 and 0.025, respectively). Compared with insulin-sensitive subjects, insulin-resistant subjects were more likely to be females (70.2% vs. 49.7%, p < 0.001), and had significantly higher BMI (26.2 +/- 3.9 kg/m2 vs. 23.7 +/- 3.3 kg/m2, p < 0.001), HOMA-IR (3.6 +/- 3.5 vs. 0.7 +/- 0.3, p < 0.001), WBC count (6686.9 +/- 1889.2/mm3 vs. 5942.9 +/- 1740.4/mm3, p < 0.001), and platelet count (243.5 +/- 70.9 x 10(3)/mm3 vs. 231.0 +/- 62.2 x 10(3)/mm3, p = 0.011), but not age (64.5 +/- 11.0 years vs. 64.6 +/- 11.4 years, p = 0.93) or RBC count (4.6 +/- 0.6 M/mm3 vs. 4.6 +/- 0.6 M/mm3, p = 0.76). When age and sex were controlled, HOMA-IR significantly correlated with WBC count (gamma = 0.23, p < 0.001) and platelet count (gamma = 0.09, p = 0.007). However, by multiple logistic regression, female gender, overweight and obesity, and elevated WBC count were all found to be independent risk factors of insulin resistance, but age, RBC and platelet counts were not. CONCLUSION: Elevated WBC count but not RBC count was significantly associated with insulin resistance and glycemic metabolism. The relationship between platelet count and insulin resistance deserves further investigations.

Health care utilization of home care patients at an academic medical center in Taiwan.

BACKGROUND: Previous surveys of home care patients in Taiwan have primarily concentrated on patients' status and needs. The aim of this study was to review the actual health care utilization of home care patients during the course of 1 year. METHODS: Home care patients at an academic medical center in Taiwan were selected and their insurance claims data at this hospital in 2001 were analyzed. Analyses included the patients' patterns and diagnoses of visits and admissions, and their drug utilization. For diagnoses made at outpatient departments, the grouping system from the National Hospital Ambulatory Medical Care Survey in the United States was used. The Anatomical Therapeutic Chemical Classification system was applied to drug grouping. RESULTS: The home care agency of the hospital cared for 165 patients (66 women, 99 men) in 2001. In total, these 165 patients received 1,358 home visits, 2,751 outpatient visits, and 108 inpatient admissions. While the most frequent diagnoses for all visits were cerebrovascular disease, hypertension, diabetes mellitus, chronic and unspecified bronchitis, psychoses, and other disorders of the central nervous system, the most frequent diagnoses at discharge from the hospital were urinary tract infection and pneumonia. In all visits, 12,282 items of drugs were prescribed in 2,337 prescriptions. On average, each prescription contained 5.3 +/- 2.8 items of drugs. The most frequently prescribed drugs were antacids, expectorants, laxatives, selective calcium channel blockers, and antithrombotic agents. CONCLUSION: The home care agency of the hospital should pay more attention to provision of comprehensive care and review of drug prescribing.

Metabolic characteristics and insulin resistance of impaired fasting glucose among the middle-aged and elderly Taiwanese.

Impaired fasting glucose (IFG), a newly defined category of glycemic metabolism, has gained extensive attentions after the introduction of the diagnostic criteria of diabetes mellitus (DM) by the American Diabetes Association. To explore the metabolic characteristics of IFG, we conducted this prospective community-based study among people aged more than 40 years residing in three major townships of I-Lan, an agricultural county in Taiwan. People attending the annual health examinations in community health stations were recruited for study. Experienced research staff recorded the past medical history, performed comprehensive physical examinations, and drew blood for further laboratory tests for each subject. Insulin resistance was evaluated by homeostasis model assessment (HOMA), and the renal hemodynamics was evaluated by estimated glomerular filtration rate (GFR). In total, 824 subjects (mean age=64.4+/-11.3 years, M:F=366:458) participated this study, the overall prevalence of DM was 15.3% (8.7% previously undiagnosed), and the prevalence of IFG was 7.2%. Lipid profiles including serum levels of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglyceride of subjects with IFG were basically indistinguishable from subjects with DM. Insulin resistance was significantly associated with the progression of glycemic metabolism (HOMA-IR of subjects with normal fasting glucose, IFG, and DM were 1.12+/-1.24, 1.88+/-1.64, 4.47+/-5.12, P<0.001). However, the prevalence of metabolic syndrome was similar among subjects of IFG and DM (86.4 versus 85.6%). The prevalence of overt proteinuria was significantly increased as the glycemic metabolism progressed. The mean GFR was slightly increased in subjects with IFG, which may represent hyperfiltration in this category. In conclusion, metabolic characteristics of IFG were complex. Lipid profile and prevalence of metabolic syndrome of IFG were indistinguishable from DM, but renal hemodynamics and prevalence of overt proteinuria were intermediate between NFG and DM. To prevent or delay the onset of type 2 DM, aggressive lifestyle modifications should be engaged in our clinical practice for subjects with IFG.

A positron emission tomography/computed tomography (PET/CT) acquisition protocol for CT radiation dose optimization.

BACKGROUND: In current combined positron emission tomography/computed tomography (PET/CT) systems, high-quality CT images not only increase diagnostic value by providing anatomic delineation of hyper- and hypometabolic tissues, but also shorten the acquisition time for attenuation correction compared with standard PET imaging. However, this technique potentially introduces more radiation burden to patients as a result of the higher radiation exposure from CT. METHODS: In this study, the radiation doses delivered from typical germanium-based and CT-based transmission scans were measured and compared using an anthropomorphic Rando Alderson phantom with insertions of thermoluminescent dosimeters. Image geometric distortion and quantified uptake values in PET images with different manipulating CT acquisition protocols for attenuation correction were also evaluated. RESULTS: It was found that radiation doses during germanium-based transmission scans were almost negligible, while doses from CT-based transmission scans were significantly higher. Using a lower radiation dose, the CT acquisition protocol did not significantly affect attenuation correction and anatomic delineation in PET. CONCLUSIONS: This study revealed the relation between image information and dose. The current PET/CT imaging acquisition protocol was improved by decreasing the radiation risks without sacrificing the diagnostic values.

Hyaline-vascular variant of Castleman's disease mimicking a gastric submucosal tumor.

Castleman's disease is a rare lymphoproliferative disorder with unknown underlying cause. Three histologic variants (hyaline-vascular, plasma cell and mixed) as well as 2 clinical groups (localized and multicentic) have been described. Most patients with the hyaline-vascular variant are asymptomatic other than localized pressure from the mass. Hyaline-vascular Castleman's disease was commonly found as intrathoracic presentation. Extrathoracic lesions have been reported in the retroperitoneum, mesentery, central nervous system, orbit, pelvis, neck, axilla, and skeletal muscles. Herein, we report a case of hyaline-vascular Castleman's disease mimicking a gastric submucosal leiomyoma that has rarely been reported in English literature review. The lesion was not actually developing from the stomach, however, the clinical presentation was mimicking a submucosal gastric tumor. Furthermore, the patient in this case had both chronic hepatitis C and splenosis. The relationship between the underlying diseases and the development of the CD deserves further investigations.

Radiation exposure during transmission measurements: comparison between CT- and germanium-based techniques with a current PET scanner.

In positron emission tomographic (PET) scanning, transmission measurements for attenuation correction are commonly performed by using external germanium-68 rod sources. Recently, combined PET and computed tomographic (CT) scanners have been developed in which the CT data can be used for both anatomical-metabolic image formation and attenuation correction of the PET data. The purpose of this study was to evaluate the difference between germanium- and CT-based transmission scanning in terms of their radiation doses by using the same measurement technique and to compare the doses that patients receive during brain, cardiac and whole-body scans. Measurement of absorbed doses to organs was conducted by using a Rando Alderson phantom with thermoluminescent dosimeters. Effective doses were calculated according to the guidelines in the International Commission on Radiation Protection Publication Number 60. Compared with radionuclide doses used in routine 2-[fluorine-18]-fluoro-2-deoxy-D-glucose PET imaging, doses absorbed during germanium-based transmission scans were almost negligible. On the other hand, absorbed doses from CT-based transmission scans were significantly higher, particularly with a whole-body scanning protocol. Effective doses were 8.81 mSv in the high-speed mode and 18.97 mSv in the high-quality mode for whole-body CT-based transmission scans. These measurements revealed that the doses received by a patient during CT-based transmission scanning are more than those received in a typical PET examination. Therefore, the radiation doses represent a limitation to the generalised use of CT-based transmission measurements with current PET/CT scanner systems.

Helicobacter pylori and hepatitis A virus infection in school-aged children on two isolated neighborhood islands in Taiwan.

BACKGROUND: The transmission routes of Helicobacter pylori and hepatitis A virus (HAV) infections have been extensively discussed in previous literature. However, whether H. pylori and HAV shared the same transmission pattern or not remains unclear. Lower socioeconomic status was recognized as a consistent risk factor to both infections. However, whether fecal-oral transmission was a risk factor to both infections is still under debate. MATERIALS AND METHODS: In 1996, we conducted a cross-sectional study to evaluate the seroprevalence of antibody to H. pylori and HAV among the randomly selected school-aged children (age between 13 and 15) on Green Island (n = 91) and Lanyu Island (n = 138) (two isolated neighborhood islands near Taiwan Main Island). RESULTS: The seroprevalence of H. pylori and HAV on the Green Island were 82.4% and 5.5%, respectively. The seroprevalence of H. pylori and HAV on Lanyu Island were 71.0% and 90.6%, respectively. H. pylori seroprevalence of all children and the subgroup of 13-year-olds was significantly lower on Lanyu Island than Green Island. However, it was not significantly different in subgroups of 14- and 15-year-olds. HAV seroprevalence was significantly higher on Lanyu Island than Green Island among all children and in each age subgroup. The correlation of H. pylori infection and HAV infection did not demonstrate significant linear correlation on both islands. CONCLUSIONS: In conclusion, H. pylori and HAV infections in school-aged children of 13-15 years of age on Green Island and Lanyu Island did not demonstrate significant correlation. The results of this study imply that H. pylori and HAV may share different transmission routes of infection.

Glucose intolerance in Chinese patients with chronic hepatitis C.

AIM: To investigate the prevalence and the risk factors of glucose intolerance in Chinese patients with chronic hepatitis C and to evaluate the relationship between interferon (IFN) treatment and glucose intolerance in these patients. METHODS: Prospective cross-sectional study was done to evaluate the prevalence of glucose intolerance in Chinese patients with chronic hepatitis C virus (HCV) infection from the outpatient clinic of Department of Family Medicine, Taipei Veterans General Hospital. Chronic hepatitis C was defined as persistent presence of anti-HCV and persistent elevation of liver transaminase for at least 1.5 folds for at least 6 months. Moreover, patients were further categorized into normal fasting glucose and glucose intolerance (diabetes mellitus (DM) and impaired fasting glucose) according to the diagnostic criteria of American Diabetic Association. RESULTS: Totally, 359 Chinese patients with chronic hepatitis C were enrolled (212 males and 147 females, mean age=58.1+/-13.0 years). One hundred and twenty-three patients (34.3 %) had received various forms of IFN treatment. One hundred and twenty-five patients (34.6 %) had glucose intolerance, including 99 patients (27.6 %) with DM and 26 patients (7.0 %) with impaired fasting glucose. In comparison with those with normal fasting glucose levels, patients with chronic hepatitis C with glucose intolerance were significantly older, had a significantly higher body mass index, and they were more likely to suffer from obesity, to have family history of diabetes and to have had previous IFN treatment. Stepwise multivariate logistic regression revealed significantly that age >=57 years, obesity, previous history of IFN treatment and the presence of family history of diabetes were independent risk factors associated with the presence of glucose intolerance in chronic hepatitis C patients. CONCLUSION: In conclusion, 34.6 % of Chinese patients with chronic hepatitis C had glucose intolerance. Chronic hepatitis C patients who were older in age, obese, had previous IFN treatment history and had family history of diabetes were prone to develop glucose intolerance. To our knowledge, this is the first population-based report to confirm that interferon treatment to be an independent risk factor to develop glucose intolerance.

Seroprevalence of Helicobacter pylori in school-aged Chinese in Taipei City and relationship between ABO blood groups.

AIM: To explore the seropositive rate of antibodies against H. pylori (anti-HP) in Taipei City and to compare the relationship of ABO blood groups and H. pylori infection. METHODS: In 1993, high school students in Shih-Lin District were randomly selected for blood samplings by their registration number at school. In addition, similar procedures were performed on the well-children clinics of Taipei Veterans General Hospital. Besides, randomly selected sera from the adults who took the physical examination were recruited for evaluation. Informed consents were obtained from all the subjects before blood samplings and parents were simultaneously informed for those who were younger than 18-year-old. Blood tests for anti-HP and ABO blood groupings were performed by enzyme-linked immunosorbent assay. Chi square tests were used for the comparisons between seroprevalence of H. pylori and ABO blood groups. RESULTS: Totally, 685 subjects were recruited (260 children aged 1-14 years, 425 high school students aged 15-18 years) were evaluated, and another 88 adult healthy volunteers were studied as well for comparison. The age-specific seropositive rate of anti-HP was 1.3 % at age 1-5 years, 7.7 % at age 6-10 years, and 11.5 % at age 11-14 years. The seroprevalence of H. pylori infection was abruptly increased in young adolescence: 18.6 % at age 15 years, 28.1 % at age 16 years, 32.4 % at age 17 years and 41.0 % at age 18 years, respectively. In the 425 high school students, ABO blood groupings were performed, which disclosed 48.5 % (206/425) of blood group O, 24 % (102/425) of blood group A, 21.8 % (93/425) of blood group B and 5.6 % (24/425) of blood group AB. In comparison of the subjects with blood group O and the other blood groups, no statistical significance could be identified in the seroprevalence of H. pylori (P=0.99). CONCLUSION: The seroprevalence of H. pylori infection in Taipei City in adults is similar to the developed countries, and the abrupt increase of H. pylori during high school may be resulted from marked increase of interpersonal social activities. Although blood group O was reported to be related to H. pylori infection in previous literature, we found no association between H. pylori infection and ABO blood groups.

Prevalence of antilipemic drug use in Taiwan: analysis of a sampling cohort within the national health insurance.

BACKGROUND: Hyperlipidemia is a major risk factor of cardiovascular diseases. We investigated the utilization ofantilipemic drugs at the outpatient sector within the National Health Insurance in Taiwan. METHODS: We obtained the first cohort (n = 50,000) dataset from the National Health Insurance Research Database and analyzed the outpatient claim files of the cohort in 2000. The antilipemic drugs were defined as the drug items belonging to the group C10 (serum lipid reducing agents) of the Anatomical Therapeutic Chemical classification system. RESULTS: Among the cohort with 46,614 eligible people, 760 patients had ever received antilipemic drugs (prevalence: 1.6%). The group 60-69 years of age had the greatest age-specific prevalence (7.2%), followed by the group over 70 years of age (6.0%). There were more male than female patients, but female patients outnumbered male patients before the age of 49 years. The antilipemic drugs had been prescribed 3,850 times totally with 70,272 defined daily doses (DDDs). On an average, a patient with antilipemic therapy received 5.1 (+/- 4.5) prescriptions of antilipemic drugs in one year and a prescription contained 18.3 (+/- 11.5) DDDs. We measured 4.1 DDDs per 1,000 inhabitants per day for all antilipemic drug use in 2000. The statins and fibrates predominated the antilipemic drug use. While gemfibrozil was most popular in respect of recipients and prescription items, simvastatin had the largest amount of use in unit of DDDs. Diabetes mellitus co-existed in 37.8% of the patients with antilipemic therapy and the standardized morbidity ratio (SMR) was 3.34. The other concomitant diseases included essential hypertension (rate: 48.8%, SMR: 2.40) and other heart disease (rate: 30.7%, SMR: 2.36). CONCLUSIONS: Statins were the leading antilipemic drugs in Taiwan. The users of antilipemic drugs were more likely to have concomitant diabetes mellitus, hypertension and heart disease.

Antibiotic prescription for fever episodes in hospice patients.

Bacterial infection usually plays an important part in the fever episodes that are common in patients in the hospice palliative care unit. The physicians' attitude to use of antibiotics in such cases is usually complex. We retrospectively studied 535 admissions to a hospice and palliative care unit in a medical center in Taiwan. Ninety-three fever episodes (16.7%) were identified among these admissions, and 79 fever episodes (84.9%) were treated with antibiotics. The Karnofsky performance status (KPS), verbal communication ability (VCA) and Glasgow Coma Scale (GCS) were all significantly compromised in these febrile patients. Although KPS, VCA and GCS were similar among all patients at the date of admission, these parameters became significantly worse in fever episodes that were left untreated than in those treated with antibiotics. Patients without antibiotic treatment showed a shorter mean survival (8.7 +/- 9.9 days vs 14.6 +/- 13.1 days; P = 0.03) and a higher 3-day mortality rate than those patients with antibiotic treatment (50% vs 15.2%; P = 0.015). In conclusion, appropriate antibiotic use may cause fever to subside and thus decrease the fever-related discomfort. Physicians may tend to withhold antibiotic treatment because of the poorer KPS, VCA, and GCS and poorer estimated prognosis of patients at the time of fever.

Huge adenomatous hyperplasia of the liver.

Adenomatous hyperplasia (AH) of the liver is defined as a regenerative overgrowth with limited growth potential. Patients with AH of the liver usually have cirrhosis of the liver as well. Adenomatous hyperplasia is also described as a benign nodule more than 8 mm, which is the main differentiation between AH and regeneration nodules (which are less than 8 mm). Adenomatous hyperplasias more than 20 mm is extremely rare in the clinicopathologic studies. We present two cases of extraordinarily large AH (one was 100 mm and the other, 30 mm). Both patients were alcoholic, and one also had viral hepatitis B. By clinical, biochemical, and upper gastrointestinal endoscopic examinations, we diagnosed liver cirrhosis in both. Sizable nodules were discovered in their livers using imaging studies (including ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography), and percutaneous liver biopsies of the nodules showed their cirrhotic background. However, neither of the patients developed hepatocellular carcinoma during the follow-up period.
