Airflow limitation as a risk factor for vascular stiffness.

BACKGROUND: Cardiovascular disease is one of the main causes of mortality in patients with chronic obstructive pulmonary disease (COPD), and atherosclerosis is a cause of cardiac comorbidities in COPD. However, it is not clear whether airflow limitation is associated with atherosclerosis irrespective of smoking.OBJECTIVE: To investigate whether airflow limitation is independently associated with vascular stiffness.METHODS: We enrolled 18 893 participants (male 70.5%; mean age 47.5 ± 9.8 years; never smokers 44.2%) who underwent spirometry and brachial-ankle pulse wave velocity (baPWV) as part of a standard health examination at Ajou University Hospital, Suwon, South Korea, from January 2010 to December 2015.We defined vascular peripheral atherosclerosis as baPWV ≥ 1400 cm/s and airflow limitation as pre-bronchodilator ratio of forced expiratory volume in 1 sec (FEV1) to forced vital capacity (FVC) <70%.RESULTS: Mean baPWV was higher in subjects with airflow limitation (1477.6 ± 331.7 cm/sec, n = 638) than in those without airflow limitation (1344.1 ± 231.8 cm/sec, n = 18255, P < 0.001). In multivariate logistic regression analysis, the following were independent predictors associated with peripheral atherosclerosis (P < 0.05): age, male sex, fasting serum glucose, mean blood pressure, serum leukocyte count, serum low density lipoprotein level and FEV1.CONCLUSION: Airflow limitation was an independent predictor of vascular stiffness irrespective of smoking history, which suggests that airflow limitation is linked with atherosclerosis.

Early detection of Mycobacterium tuberculosis complex in BACTEC MGIT cultures using nucleic acid amplification.

We evaluated the application of nucleic acid amplification (NAA) in liquid cultures for the early detection of Mycobacterium tuberculosis. The Cobas TaqMan MTB test, IS6110 real-time PCR, and hsp65 PCR-restriction fragment length polymorphism (RFLP) analysis were used to detect BACTEC MGIT 960 (MGIT) cultures on days 3, 5, 7, and 14. The procedure was initially tested with a reference strain, H37Rv (ATCC 27294). Subsequently, 200 clinical specimens, including 150 Acid Fast bacillus (AFB) smear-positive and 50 AFB smear-negative samples, were examined. The Cobas TaqMan MTB test and IS6110-based PCR analysis were able to detect M. tuberculosis after 1 day when the inoculum of H37Rv was >3 x 10(-2) CFU/ml. After a 5-day incubation in the MGIT system, all three NAA assays had a positive detection regardless of the inoculum size. After a 1-day incubation of the clinical specimens in the MGIT system, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for the Cobas TaqMan MTB assay were 70.2%, 100%, 100%, and 82.3% respectively. For IS6110-based PCR analysis, these values were 63.1%, 100%, 100%, and 78.9%, and were 88.1%, 100%, 100%, and 92.1% respectively for hsp65 PCR-RFLP analysis. After a 3-day incubation, the specificity and PPV were 100% for all three NAA tests; the Cobas TaqMan MTB assay had the best sensitivity (97.6%) and NPV (98.3%). The sensitivity, specificity, PPV, and NPV for conventional culture analysis were 98.8%, 100%, 100%, and 99.1%. Thus, NAA may be useful for the early detection of M. tuberculosis after 3 days in MGIT.

Unique features of non-obstructive emphysema and pure airway obstruction.

SETTING: Emphysema without airway obstruction or airway obstruction without emphysema are often detected clinically, although they are commonly co-existent. We therefore tested the hypothesis that non-obstructive emphysema and pure airway obstruction have unique features. METHODS: A case-control observation study was undertaken retrospectively in a patient cohort at a single centre. Among 2662 subjects who underwent chest computed tomography and pulmonary function tests, we enrolled 90 patients with non-obstructive emphysema, 119 with pure airway obstruction, 81 with obstructive emphysema and 2031 subjects as normal controls. The features of the four groups were analysed and compared. RESULTS: Higher serum homocysteine (13.4 ± 7.4 vs. 11.6 ± 4.6 mol/l), higher rate of osteoporosis (15.8% vs. 4.5%), higher leukocyte count, higher male ratio, lower serum albumin and lower body mass index were observed in subjects with non-obstructive emphysema than in controls (P < 0.05). In multiple logistic regression analysis of groups without airway obstruction, osteoporosis, hyperhomocysteinaemia, hypoalbuminaemia and higher leukocyte count were independent factors associated with non-obstructive emphysema (P < 0.05). CONCLUSION: Hyperhomocysteinaemia, hypoalbuminaemia, osteoporosis and higher leukocyte count were independent predictors of non-obstructive emphysema.

Neural substrates, experimental evidences and functional hypothesis of acupuncture mechanisms.

OBJECTIVES: Although acupuncture therapy has demonstrated itself to be effective in several clinical areas, the underlying mechanisms of acupuncture in general and the analgesic effect in particular are, however, still not clearly delineated. We, therefore, have studied acupuncture analgesic effect through fMRI and proposed a hypothesis, based on the obtained result, which will enlighten the central role of the brain in acupuncture therapy. METHODS: The proposed model, termed as a broad sense hypothalamus-pituitary-adrenal (BS-HPA) axis, was based on our observed neuroimaging results. The model incorporates the stress-induced HPA axis model together with neuro-immune interaction including the cholinergic anti-inflammatory model. RESULTS: The obtained results coupled with accumulating evidence suggest that the central nervous system is essential for the processing of these effects via its modulation of the autonomic nervous system, neuroimmune system and hormonal regulation. CONCLUSIONS: Based on our fMRI study, it appears that understanding the effects of acupuncture within a neuroscience-based framework is vital. Further, we have proposed the broad sense-HPA axis hypothesis which incorporates the experimental results.

The addition of induction chemotherapy with etoposide, ifosfamide, and cisplatin failed to improve therapeutic outcome of concurrent chemoradiotherapy in patients with locally advanced non-small cell lung cancer -- single institution retrospective analysis.

Although chemoradiotherapy (CRT) is a standard treatment for unresectable locally advanced non-small cell lung cancer (NSCLC), the optimal sequencing remains to be determined. We retrospectively compared the treatment results of induction chemotherapy followed by concurrent CRT (induction group, 32 patients) with those of concurrent CRT alone (concurrent group, 41 patients) in unresectable stage IIIA/IIIB NSCLC patients. In induction group, 2 cycles of induction chemotherapy (etoposide/ifosfamide/cisplatin: 24 patients, others: 8 patients) were followed by concurrent CRT (60 Gy/30 fractions, 6 mg/m2 of cisplatin daily), while the same concurrent CRT was administered in concurrent group. Clinicopathologic characteristics including age, weight loss, histologic types, and clinical stage did not show significant differences between two groups except for a higher proportion of patients with ECOG performance status 2 in concurrent group (3% vs. 27%, p=0.015). Overall toxicity was generally acceptable with 1 treatment-related death from tracheoesophageal fistula in induction group. The response rates after concurrent CRT were 41% for induction group and 54% for concurrent group, which showed no significant difference (p=0.560). With median follow-up of 13 (1-92) months, there was a trend toward an advantage for concurrent group in median progression-free survival (6 months vs 8.3 months, p=0.067) and overall survival (12 months vs. 14.5 months, p=0.059). In multivariate analysis, only more than 10% weight loss within 6 months was significantly associated with poor survival (p=0.001). In conclusion, the addition of induction chemotherapy to concurrent CRT did not show any advantage over concurrent CRT alone in locally advanced NSCLC.

Concomitant fractures of the femoral head and neck without hip dislocation.

This case report describes two patients who sustained ipsilateral fractures of the femoral head and femoral neck without dislocation of the hip. The fractures in the two patients resulted from vehicle accidents. The femoral head was fractured in the sagittal plane, and the femoral neck was fractured at the subcapital portion. However, the hip was not dislocated in either patient. Both patients were treated using cementless total hip arthroplasty. These unusual hip injuries have not been reported previously and are not categorized according to any known classification system of hip injuries.

Vascular endothelial growth factor in the serum of patients with non-small cell lung cancer: correlation with platelet and leukocyte counts.

BACKGROUND: Vascular endothelial growth factor (VEGF) is a potent angiogenic peptide expressed in a wide variety of tumors, and it stimulates angiogenesis and increases vascular permeability. Increased expression of VEGF may be associated with advanced stage and poor prognosis in patients with non-small cell lung cancer (NSCLC). METHODS: Using enzyme-linked immunosorbent assay, the levels of VEGF were determined in serum from 41 patients with untreated NSCLC (Stage: IIB, 3; IIIA, 6; IIIB, 17; IV, 15; HISTOLOGY: squamous cell carcinoma, 18; adenocarcinoma. 14; undetermined, 9). RESULTS: The median VEGF level was 312 pg/ml, ranging from 70 to 1440 pg/ml. Patients were divided into high VEGF (>312 pg/ml) and low VEGF (< or =312 pg/ml) groups using the median value as a cut-off. There were no significant associations between the serum VEGF levels and various clinicopathologic characteristics including age, gender, histologic type, stage and treatment. A significant positive correlation was found between serum VEGF levels and platelet counts (r=0.495; P=0.001). In addition, serum VEGF levels also correlated with leukocyte counts (r=0.478; P=0.002). In seven patients with measurement of follow-up serum VEGF levels at the end of treatment (chemotherapy and/or radiotherapy), the median serum VEGF level significantly decreased after the treatment (416 pg/ml; range, 96-812 pg/ml vs. 185 pg/ml; range, 49-487 pg/ml; P=0.028). However, the median platelet count (317,000/microl; range, 190,000-395,000/microl vs. 246,000/microl; range, 72,000-271,000/microl; P=0.028) and leukocyte count (10,000/microl; range, 8700-17,200/microl vs. 5100/microl; range, 3900-9500/microl; P=0.018) also decreased after the treatment. There was no statistically significant difference in the median survival of the patients between high VEGF group and low VEGF group (8 months vs. 9 months, P=0.647). CONCLUSIONS: Although serum VEGF level was significantly associated with platelet and leukocyte counts in NSCLC patients, it did not correlate with tumor burden and prognosis of the patients.

A WEB-based telePACS using an asymmetric satellite system.

We have developed a WWW-based TelePACS that can access every permitted PACS server via the Internet. Java programming techniques were used to implement the system, which can access and retrieve medical information and images through Web browsers only such as Netscape without specific tools. We also have developed a consolidator that performs as a manager to connect a conventional PACS server to a Web-based TelePACS server. We have developed the Asymmetric Satellite Data Communication System (ASDCS) as a fast communication system. The ASDCS uses a receive-only satellite link for data delivery and a terrestrial network for control communication. In conclusion, we were able to develop a cost-effective and fast PACS using Web technology. Web technology expanded the scope of use for a dedicated PACS from intrahospital to public use.

The imbalance between coagulation and fibrinolysis is related to the severity of the illness and the prognosis in sepsis.

OBJECTIVES: The coagulation and fibrinolytic system appears to be activated by the septic process independently, leading to the syndrome of disseminated intravascular coagulation (DIC). In this study, we investigated the changes within the hemostatic system related to the severity of the illness and the prognosis in patients with sepsis. METHODS: Plasma thrombin-antithrombin III (TAT) and plasmin-alpha 2-antiplasmin (PAP) complexes were measured using ELISA methods in 32 patients with sepsis and 20 controls and were analyzed according to the APACHE III scores and survival of the patients. RESULTS: Plasma TAT and PAP in patients with sepsis were significantly higher than controls. Nonsurvivors showed greater levels of TAT (21.7 +/- 22.3 ng/mL) and lower levels of PAP (628.4 +/- 378.1 ng/mL) than survivors (TAT: 11.1 +/- 11.2 ng/mL; PAP: 857.1 +/- 364.1 ng/mL). The imbalance between coagulation and fibrinolysis described as TAT/PAP ratio was closely related with APACHE III scores in patients with sepsis (r = 0.47) and the TAT/PAP ratio in nonsurvivors was significantly higher compared with survivors (34.4 +/- 21.4 vs. 14.4 +/- 13.8). CONCLUSION: In sepsis, both coagulation and the fibrinolysis system are activated and the imbalance between coagulation and fibrinolysis predisposes to the hypercoagulation state and is closely related to the severity of the disease and the prognosis.

Signal transduction pathway in human middle ear cholesteatoma.

Phospholipase C-gamma1 plays a central role in signal transduction, and it is important in cellular growth, differentiation, and proliferation. Human cholesteatoma in the middle ear is characterized by the presence of a keratinizing epithelium that is believed to have hyperproliferative properties. The purpose of this study is to elucidate the distribution of phospholipase C-gamma1 in cholesteatoma matrix and deep meatal skin with Western blot analysis and immunohistochemistry. In conclusion, overexpression of phospholipase C-gamma1 in cholesteatoma matrix suggests a possible derangement of enhanced growth signal transduction in keratinocytes.

AHNAK, a protein that binds and activates phospholipase C-gamma1 in the presence of arachidonic acid.

We have recently shown that phospholipase C-gamma (PLC-gamma) is activated by tau, a neuronal cell-specific microtubule-associated protein, in the presence of arachidonic acid. We now report that non-neuronal tissues also contain a protein that can activate PLC-gamma in the presence of arachidonic acid. Purification of this activator from bovine lung cytosol yielded several proteins with apparent molecular sizes of 70-130 kDa. They were identified as fragments derived from an unusually large protein (approximately 700 kDa) named AHNAK, which comprises about 30 repeated motifs each 128 amino acids in length. Two AHNAK fragments containing one and four of the repeated motifs, respectively, were expressed as glutathione S-transferase fusion proteins. Both recombinant proteins activated PLC-gamma1 at nanomolar concentrations in the presence of arachidonic acid, suggesting that an intact AHNAK molecule contains multiple sites for PLC-gamma activation. The role of arachidonic acid was to promote a physical interaction between AHNAK and PLC-gamma1, and the activation by AHNAK and arachidonic acid was mainly attributable to reduction in the enzyme's apparent Km toward the substrate phosphatidylinositol 4,5-bisphosphate. Our results suggest that arachidonic acid liberated by phospholipase A2 can act as an additional trigger for PLC-gamma activation, constituting an alternative mechanism that is independent of tyrosine phosphorylation.

Neutrophil infiltration and release of IL-8 in airway mucosa from subjects with grain dust-induced occupational asthma.

BACKGROUND: The immuno-pathological mechanism for occupational asthma induced by grain dust (GD) remains to be clarified. There have been few reports suggesting the involvement of neutrophils inducing bronchoconstriction after inhalation of GD. OBJECTIVE: To further understand the role of neutrophil in the pathogenesis of GD-induced asthma. MATERIALS AND METHODS: We studied the phenotype of leucocytes of the bronchial mucosa in patients with GD-induced asthma. Bronchial biopsy specimens were obtained by fibreoptic bronchoscopy from six subjects with GD-induced asthma. Six allergic asthma patients sensitive to house dust mite were enrolled as controls. Bronchial biopsy specimens were examined by immunohistochemistry with a panel of monoclonal antibodies to tryptase-containing mast cell (AA1), activated eosinophil (EG2), pan T-lymphocyte (CD3) and neutrophil elastase (NE). Induced sputum was collected before and after the GD-bronchoprovocation test. The IL-8 level in the sputum was measured using ELISA. RESULTS: There was a significant increase in the number of AA1+ and NE+ cells in bronchial mucosa of GD-induced asthma, compared with those of allergic asthma (P=0.01, P=0.01, respectively). No significant differences were observed in the number of EG2+ and CD3+ cells (P = 0.13, P=0.15, respectively). IL-8 was abundant in the sputum of all GD-induced asthma patients and significantly increased after the bronchial challenges compared with the baseline value (P = 0.03). CONCLUSION: These findings support the view that neutrophil recruitment together with mast cells may contribute to the bronchoconstriction induced by GD. A possible involvement of IL-8 was suggested.

Immunohistochemical characterization of the cellular infiltrate in airway mucosa of toluene diisocyanate (TDI)-induced asthma: comparison with allergic asthma.

Toluene diisocyanate (TDI) is the most prevalent agent in occupational asthma (OA) in Korea. The immuno-pathologic mechanism for TDI-induced bronchoconstriction remains to be clarified. We studied the immunohistochemical finding of inflammatory cells in bronchial mucosa in subjects with TDI-induced asthma. Fiberoptic bronchial biopsy specimens were obtained from nine subjects with TDI-induced asthma. Six allergic asthma sensitive to house dust mite were enrolled as controls. Bronchial biopsy specimens were examined by immunohistology with a panel of monoclonal antibodies to mast cell tryptase (AA1), secretary form of eosinophil cationic protein (EG2), pan T-lymphocyte (CD3) and neutrophil elastase (NE). There was a significant increase in the number of AA1+, EG2+ and NE+ cells in TDI-induced asthma compared to those of allergic asthma (p=0.02, p=0.04, p=0.03, respectively). No significant differences were observed in the number of CD3+ cells (p=0.27). These findings support the view that neutrophil recruitment together with eosinophil and mast cell, may contribute to the bronchoconstriction induced by TDI.

Activation of phospholipase C-gamma by the concerted action of tau proteins and arachidonic acid.

Phospholipase C-gamma (PLC-gamma) isozymes are thought to be activated by receptor-induced tyrosine phosphorylation. Proteins that activate PLC-gamma1 have now been purified from bovine brain and identified as members of the tau family of microtubule-associated proteins. Activation of PLC-gamma by tau was enhanced in the presence of unsaturated fatty acids such as arachidonic acid, saturated fatty acids being ineffective. Maximal (15-20-fold) activation was apparent in the presence of 0.15 microM tau and 25 microM arachidonic acid (AA). The effect of tau and AA was specific to PLC-gamma isozymes in the presence of submicromolar concentrations of Ca2+ and was markedly inhibited by phosphatidylcholine. These results suggest that in cells that express tau, receptors coupled to cytosolic phospholipase A2 may activate PLC-gamma isozymes indirectly in the absence of tyrosine phosphorylation through the hydrolysis of phosphatidylcholine to generate AA.

Distribution of phospholipase C isozymes in normal human lung tissue and their immunohistochemical localization.

Phospholipase C(PLC) plays a central role in signal transduction and it is important in cellular growth, differentiation and transformation. There are currently ten known mammalian isozymes of PLC identified and cloned. However, there are no report of PLC distribution in human lung tissue or their significances in pulmonary diseases. Presence of various PLC isozymes in normal human lung tissue was studied from surgical specimens. PLC isozymes in tissue extracts of the lung were partially purified by successive chromatographic steps on heparin-sepharose CL-6B conventional and TSKgel heparin-5PW HPLC columns and their activities were assayed. PLC activity peaks identified in the chromatography were immunoblotted with specific antibodies against ten known mammalian PLC isozymes(PLC-beta 1-4, -gamma 1-2, and -delta 1-4). In addition, immunohistochemical staining of the lung tissue was performed to determine subcellular and histological localization of PLC isozymes. The results indicate that normal human lungs contain beta 1, beta 3, gamma 1, and delta 1, isozymes of PLC. The order of amount present in the lung tissue was PLC-delta 1 > gamma 1 > beta 1 >> beta 3, in descending order. On immunohistochemistry, PLC-gamma 1 was most widely distributed and was present in bronchiolar epithelium, in type I and type II pneumocytes as well as in fibroblasts of the interstitial tissue. PLC-delta 1 was present in the cytoplasm of the bronchiolar epithelium whereas PLC-beta 1 was localized to the apical membranous portion of the same epithelium. PLC-beta 3 was seen in the nucleus of the respiratory and alveolar lining epithelium as well as in the nucleus of lung fibroblasts.

Pheochromocytoma of the urinary bladder: a case report.

A 61-year-old female was admitted who had had symptoms of hematuria and a tumor mass in the urinary bladder for six months. Hypertension and headache after micturition had been noted for one year. Plasma norepinephrine before and after voiding were elevated. Increased I-131 metaiodobenzylguanidine (I-131 MIBG) uptake in the urinary bladder was also found. The plasma norepinephrine level and blood pressure returned to normal after partial cystectomy. Diagnosis of pheochromocytoma was confirmed by histology.

Theophylline disposition in Korean patients with congestive heart failure.

OBJECTIVE: This study proposed to determine the systemic disposition of theophylline in Korean adult patients during decompensated congestive heart failure compared with disposition after recovery. DESIGN: An experimental, prospective, self-controlled, nonrandomized design was used. SETTING: The study was performed in a general community hospital located in Pusan, Korea. PATIENTS: Eight nonsmoking elderly Korean patients with decompensated congestive heart failure presenting to the emergency department were included in the study. Consecutive patients who met entrance criteria were selected. All patients completed the study. INTERVENTIONS: A single dose of aminophylline 6 mg/kg was administered by intravenous infusion over 30 minutes. Standard methods of congestive heart failure therapy were used in each patient, including bed rest, restriction of sodium, and drug therapy including digoxin. After compensation of congestive heart failure was achieved, the theophylline infusion was repeated. OUTCOME MEASURES: Serum theophylline concentrations were measured at 2, 6, 12, and 18 hours after completion of the dose at baseline and following treatment. RESULTS: A clinically and statistically significant improvement in mean theophylline total body clearance was demonstrated following treatment (from 21.7 +/- 2.8 to 43.4 +/- 4.7 mL/kg/h [mean +/- SEM]; p < 0.01). Comparison of these results with a computer model based on literature averages of peoples of all nationalities showed significant underprediction of theophylline clearance both before (p < 0.05) and after (p < 0.01) treatment. The theophylline elimination half-life prior to treatment was 18.2 +/- 2.2 hours and decreased to 9.1 +/- 0.8 hours following treatment (p < 0.01). There was no statistical difference between the computer-model predicted initial theophylline half-life and the measured value, but the model significantly underpredicted the improvement following treatment. CONCLUSIONS: The improvement in theophylline clearance demonstrated in this study appears to be greater than that reported for Western patients. This has practical application to the calculation of appropriate theophylline maintenance dosage regimens in Korean patients with cardiac failure. These data support the need for consideration of racial differences in individualizing dosage regimens. We suggest that all kinetic models, whether software supported or not, should consider incorporating ethnic origin as a demographic factor that helps select the proper model for individual patients.

Possible role of high-titer maternal viremia in perinatal transmission of hepatitis C virus.

To study perinatal transmission of hepatitis C virus (HCV), 15 anti-HCV-positive carrier mothers without human immunodeficiency virus coinfection were recruited. At delivery, maternal blood was taken and anti-HCV titer was determined and HCV RNA measured in each serum sample by reverse transcription polymerase chain reaction (PCR). A competitive PCR was used in selected samples to quantitate HCV concentration. The 15 neonates were followed regularly for 1 year and their sera were also assayed for anti-HCV and for HCV RNA by reverse transcription PCR. All the mothers were positive for HCV RNA. Only one normal spontaneously delivered neonate of a mother with extremely high titer of anti-HCV (1:20,000) and HCV concentration (10(10) copies/mL) had both anti-HCV and HCV RNA in serum for up to 6 months of age. In contrast, none of the remaining 14 neonates born to mothers with low- to high-titer anti-HCV (1:4-1:1000) and moderate amounts of HCV RNA (10(5)-10(6) copies/mL) contracted HCV infection. The results imply that high-titer maternal viremia and normal spontaneous delivery may allow more HCV to infect the neonate intrapartum, therefore establishing perinatal transmission.

[A pilot study of nursing activities on the Chest Medicine Ward at KMCH].

The current study sought to establish a preliminary patient classification system by determining how much time nurses spend each shift on their various activities. In this way we hoped to determine the direct care needs of the patient. From August 11 through the 17, snap-shot observations on the Chest Medicine Ward of Kaohsiung Medical College Hospital were taken every five minutes throughout the day to evaluate nursing activities and health care needs of patients. After employing such statistical techniques as percentage comparison, One-way ANOVA on the collected data, we gained a preliminary understanding of the distribution, characteristics, extent and nature of nursing activities. The results demonstrated that the average working hours of the day shift and the evening shift are 8.13 and 8.05 hours respectively. The night shift may be as long as 8.52 hours. Our studies also revealed that the most demanding nursing activity is indirect care (50.73%), direct care (29.39%), individual time (13.73%) and related activities (6.15%) follow. In the direct care of patient, nurses devoted most of their time monitoring vital signs, administering medication, assisting in examination and treatment, caring for, and communicating with patients. On hygiene, physical movements and the clean up of body discharges were mostly devoted by patients and families.

Subacute thyroiditis--61 cases review.

To examine the hospitalized patients with available data suggesting subacute thyroiditis, we have reviewed 80 hospital charts over the last 11 years and the data demonstrated 61 patients (48 females, 13 males, Aged 22-75 years) had evidence of subacute thyroiditis clinically or pathologically. Fifty seven of those patients had the clinical manifestation of severe tenderness over the neck, and others were painless. The thyroid function test were abnormal in 53% (30/57) of cases. All had rapid sedimentation rate (46/46). The thyroid antibodies were positive in 26% (10/39) of cases. Sixteen patients received unnecessary thyroid operation and complicated with hypothyroidism with or without hypoparathyroidism in two cases. In conclusion, all patients with painful or painless goiter should be appreciated carefully with additional study such as aspiration cytology to avoid misdiagnosis and inappropriate management.
