INTRODUCTION
Traumatic displaced femoral neck fractures in the elderly can be treated with cemented or uncemented hemiarthroplasty with good outcomes. Earlier studies reported a higher incidence of deep vein thrombosis (DVT) associated with cemented prostheses in elective total hip or knee arthroplasty. In addition, the hypercoagulable state after a traumatic femoral neck fracture and possible thrombogenic properties of bone cement could put these patients at greater risk for thromboembolism. We aimed to compare the incidence of DVT and progression to pulmonary embolism (PE) or mortality in cemented and uncemented hemiarthroplasty.METHODS
The data of 271 patients treated with cemented or uncemented hemiarthroplasty after a traumatic displaced femoral neck fracture was retrospectively analysed for the incidence of DVT. The level of thrombosis, progression to PE and mortality were compared.RESULTS
There were 133 (49.1%) patients with cemented hemiarthroplasty, while 138 (50.9%) had uncemented hemiarthroplasty. The patients had an average age of 76.6 (range 53–99) years and 11 (4.1%) patients had DVT. There were no significant differences in development of DVT, level of thrombosis, PE and mortality regardless of whether a cemented or an uncemented prosthesis was used.CONCLUSION
Cemented hemiarthroplasty is not associated with higher risks of DVT, PE or mortality in patients with traumatic displaced femoral neck fracture. Cemented prostheses can be safely used for this group of patients. 相似文献2.

Background
Stage III and IV cancers of larynx and hypopharynx often require total laryngectomy which leaves the patient with severe communication handicap. In such laryngectomised patients tracheo-esophageal puncture is the best way for voice rehabilitation using either Blom-Singer® prosthesis or Provox® indwelling valve.Methods
A prospective comparative study of Blom-Singer® prosthesis and Provox® indwelling valves placed in Tracheo-esophageal Punctures (TEP) for voice rehabilitation following total laryngectomy was carried out at the Tata Memorial Hospital, Mumbai and Malignant Diseases Treatment Centre of Armed Forces, to assess their efficacy. This report comprises of our experience in 41 (39 males and two females) laryngtectomees who underwent TEP of which 15 patients were fitted with low pressure Blom-Singer® prostheses and 26 with Provox® indwelling prostheses.Results
Prostheses related problems like granuloma formation, leakage, candidal growth over the valves and prosthetic decay were significantly less in the patients fitted with Provox® prosthesis. Dislodgement of prosthesis with closure of the tract or persistent fistula formation and creation of false passage, while reinsertion were problems encountered in the Blom-Singer group. After three months, speech assessment revealed a better quality of voice production and patient compliance in maintaining the prosthesis in the case of Provox® indwelling valve.Conclusion
In Indian scenario where illitracy amongst the patients hinders in maintainence of Blom-Singer® prosthesis, Provox® indwelling value is an appropriate choice for voice rehabilitation.Key Words: Tracheo-esophageal puncture (TEP), Blom-Singer® prosthesis, Provox® Valve 相似文献3.

INTRODUCTION
No single study has established the superiority of one treatment of Kienböck’s disease over the other. Pooled outcome data is presently considered the best way to add to the knowledge and understanding of Kienböck’s disease.METHODS
A total of 12 patients (9 male and 3 female) with Kienböck’s disease were included in the present case series. The mean age of the 12 patients was 28 years. One patient presented in Lichtman stage I, five in Lichtman stage II, five in Lichtman stage IIIa, and one in Lichtman stage IV. Univariate and multivariate analyses of the obtained data were performed to identify any correlations.RESULTS
The mean follow-up time was 62 months, and the mean modified Mayo wrist score improved from the preoperative value of 29.5 to the final value of 89.6. Lichtman stage at presentation showed moderate positive correlation with the duration of symptoms (r = 0.56), and a strong negative correlation with the preoperative and final modified Mayo scores (r = –0.89 and r = –0.77, respectively). The final modified Mayo score showed moderate negative correlation with the duration of the symptoms (r = –0.55). There was a significant difference in the preoperative modified Mayo scores of patients who presented in stage II and those of patients who presented in stage IIIa (p = 0.03). However, the difference in the final modified Mayo scores of the patients in these stages was not significant (p = 0.14).CONCLUSION
Lichtman’s stage is moderately related to the duration of symptoms, suggesting natural progression of the disease. The final outcomes of stages II and IIIa were the same irrespective of the surgical treatment (radial shortening and/or vascularised bone grafting). 相似文献5.

INTRODUCTION
Although childhood autoimmune hepatitis (AIH) has been extensively investigated in the West, data on AIH in the East is lacking. We aimed to investigate AIH’s clinical, biochemical and histological features, as well as its outcomes, in one of Singapore’s two major paediatric units.METHODS
This was a retrospective study of children diagnosed with AIH in the paediatric unit of National University Hospital, Singapore, over the last 12 years. Children with de novo AIH after liver transplantation were excluded. The demographic and clinical features of the patients, and their laboratory, treatment and clinical outcomes were reviewed.RESULTS
This study comprised ten patients (six females, four males), with a median age of 5.1 (range 2.1–13.8) years at diagnosis. Five patients had inflammatory bowel disease (IBD). Seven patients had type 1 AIH, and three had autoimmune sclerosing cholangitis (ASC) and IBD; none had type 2 AIH. The median level of aspartate aminotransferase at diagnosis was 183 (range 45–2,649) U/L. Prednisolone 1 mg/kg/day was prescribed at diagnosis for eight patients. Two patients were lost to follow-up and were treated symptomatically when they re-presented with end-stage liver disease. Azathioprine or mycophenolate mofetil was prescribed after 3–7 months of treatment. Normalisation of aminotransferase levels took an average of 5.3 (range 1–39) months.CONCLUSION
AIH is a rare but important cause of liver pathology. Children in this region with elevated aminotransferases or unexplained hepatomegaly should be screened for AIH. 相似文献6.
INTRODUCTION
Arthroscopic excision of the hypertrophic dorsal synovium is performed on patients with dorsal wrist pain in hyperextension. Although dorsal wrist impingement has been described in cadaveric studies, to our knowledge, there is no published clinical data on its treatment with arthroscopic synovial excision. Herein, we present the results of arthroscopic management of this condition in our hospital.METHOD
A total of 13 patients underwent arthroscopic excision of the hypertrophic dorsal impinging synovium. All patients presented with the cardinal symptom of dorsal-radial wrist pain in extreme extension. The diagnoses were made after excluding other causes and confirmed on wrist arthroscopy. Arthroscopy was offered after nonoperative measures failed. The mean postoperative follow-up period was 14 (range 6–31) months.RESULTS
Mean pre-and postoperative quick Disabilities of the Arm, Shoulder and Hand scores were 49 (range 34–82) and 17 (range 0–48), respectively; paired t-test revealed a significant difference between the two (p < 0.001). Mean postoperative flexion-extension arc and radial-ulnar deviation arc were 120º and 46º, respectively. Postoperatively, one patient developed complex regional pain syndrome, with tethering of the dorsal branch of the ulnar nerve, which required surgical release, while another patient required revision arthroscopic excision of the impinging tissue. Both patients had good postoperative outcomes.CONCLUSION
When treating patients with dorsal wrist pain, dorsal wrist impingement caused by synovial hypertrophy should be included in the differential diagnosis. Arthroscopic excision of the impinging synovium can achieve reliable pain relief with significant functional improvement in the short term, although further research on its long-term benefits is required. 相似文献7.
INTRODUCTION
Penile cancer is an uncommon disease affecting only about one in 100,000 men worldwide in a year. The diagnosis of the condition is frequently delayed, and the disease and its treatment frequently result in significant morbidity in patients.METHODS
We herein describe seven cases of penile tumours: six cases of squamous cell carcinomas and one case of B-cell lymphoma that presented to our hospital’s urology department between March 2011 and October 2012. We reviewed the literature to discuss the clinical presentation, natural history and current management of penile cancer.RESULTS
The patients were followed up for 1–24 months. They were managed according to their disease stage and lymph node status. Four out of seven patients showed disease progression during the follow-up period.CONCLUSION
The accurate staging of inguinal nodes in cases of low-risk disease is important to prescribe appropriate surgery for the inguinal nodes. Aggressive management of inguinal and pelvic lymph nodes remains the cornerstone in the treatment of high-risk disease cases. 相似文献8.
INTRODUCTION
The objective of this study was to examine the clinical outcome of single-level lumbar artificial disc replacement (ADR) compared to that of transforaminal lumbar interbody fusion (TLIF) for the treatment of symptomatic degenerative disc disease (DDD) in an Asian population.METHODS
This was a retrospective review of 74 patients who had surgery performed for discogenic lower backs that involved only the L4/5 and L5/S1 levels. All the patients had lumbar DDD without radiculopathy or spondylolithesis, and concordant pain with discogram at the pathological level. The patients were divided into two groups – those who underwent ADR and those who underwent TLIF.RESULTS
A trend suggesting that the ADR group had better perioperative outcomes (less blood loss, shorter operating time, shorter hospital stay and shorter time to ambulation) than the TLIF group was observed. However, a trend indicating that surgical-approach-related complications occurred more frequently in the ADR group than the TLIF group was also observed. The rate of revision surgery was comparable between the two groups.CONCLUSION
Our findings suggest that for the treatment of discogenic lower back pain, lumbar ADR has better perioperative outcomes and a similar revision rate when compared with TLIF. However, the use of ADR was associated with a higher incidence of surgical-approach-related complications. More studies with bigger cohort sizes and longer follow-up periods are needed to determine the long-term efficacy and safety of ADR in lumbar DDD. 相似文献9.
INTRODUCTION
Herpes simplex virus type 2 (HSV-2) is the most common cause of genital herpes. Glycoprotein G (gG) is a prototype antigen for type-specific serodiagnosis distinguishing between HSV type 1 (HSV-1) and HSV-2 infections. As immunological diagnosis kits for accurate differentiation between HSV-1 and HSV-2 antibodies can be expensive, there is a need to develop a convenient, sensitive, specific and cost-effective serodiagnostic kit.METHODS
We successfully expressed a fragment of gG comprising residues 321–580 of HSV-2 with histidine tag (gG321–580His) in a Bac-to-Bac baculovirus expression system, which had an antigenicity similar to its native counterpart. An indirect enzyme-linked immunosorbent assay (ELISA) was developed using gG321–580His as the diagnostic antigen and evaluated by comparison with a commercial HerpeSelect 2 ELISA immunoglobulin G kit as reference.RESULTS
In testing 318 field serum samples, the diagnostic relative sensitivity and specificity of the developed gG321–580His-ELISA test in qualitative comparison with the commercial kit were 93.81% and 96.74%, respectively, and the accuracy was 94.65%.CONCLUSION
The study indicates that gG321–580His has a high diagnostic potential for HSV-2 virus serodiagnosis in humans. 相似文献10.
INTRODUCTION
To investigate the feasibility and clinical efficacy of using a toothed plate and hollow lag screw in the surgical treatment of posterior cruciate ligament (PCL) avulsion fractures of the tibia.METHODS
A total of 21 patients were treated with open reduction and internal fixation using a toothed plate and hollow lag screw, through a posteromedial approach using an inverted L-shaped incision. The patients were allowed appropriate functional exercises, including knee flexion and extension, after removal of the plaster at postoperative weeks 3–6. The follow-up period was between six months and two years.RESULTS
This was a retrospective study of patients with PCL avulsion fractures of the tibia caused by road traffic accidents (n = 9), sports-related injuries (n = 6), falls (n = 5) and machinery-related injuries (n = 1). 20 patients presented with fresh fractures and one with an old fracture. The patients (13 men, eight women) had a mean age of 41.5 (range 19–72) years. Anatomical reduction of the fracture and satisfactory fixation were achieved in all 21 patients. Bony union was achieved in all patients at 8–12 weeks after surgery. Six months after surgery, knee flexion was 121.9° ± 10.4° and extension was 0°. According to the Lysholm Knee Scoring Scale, 19 patients were rated as ‘excellent’ and two as ‘good’.CONCLUSION
The use of a toothed plate and hollow lag screw could be a simple and reliable approach for PCL avulsion fractures of the tibia. Patients achieved good knee function after surgery. 相似文献11.

INTRODUCTION
We assessed the predictors of poor glycaemic control among older patients with type 2 diabetes mellitus (T2DM) in Malaysia.METHODS
This cross-sectional study used the data of 21,336 patients aged ≥ 60 years with T2DM from the Adult Diabetes Control and Management Registry 2008–2009.RESULTS
Predictors of poor glycaemic control were: age groups 60–69 years (odds ratio [OR] 1.96, 95% confidence interval [CI] 1.66–2.33) and 70–79 years (OR 1.43, 95% CI 1.20–1.71); Malay (OR 1.53, 95% CI 1.41–1.66) and Indian (OR 1.32, 95% CI 1.19–1.46) ethnicities; T2DM durations of 5–10 years (OR 1.46, 95% CI 1.35–1.58) and > 10 years (OR 1.75, 95% CI 1.59–1.91); the use of oral antidiabetic agents only (OR 5.86, 95% CI 3.32–10.34), insulin only (OR 17.93, 95% CI 9.91–32.43), and oral antidiabetic agents and insulin (OR 29.42, 95% CI 16.47–52.53); and elevated blood pressure (OR 1.10, 95% CI 1.01–1.20), low-density lipoprotein cholesterol (OR 1.48, 95% CI 1.38–1.59) and triglycerides (OR 1.61, 95% CI 1.51–1.73). Hypertension (OR 0.71, 95% CI 0.64–0.80), hypertension and dyslipidaemia (OR 0.68, 95% CI 0.61–0.75), pre-obesity (OR 0.89, 95% CI 0.82–0.98) and obesity (OR 0.76, 95% CI 0.70–0.84) were less likely to be associated with poor glycaemic control.CONCLUSION
Young-old and middle-old age groups (i.e. < 80 years), Malay and Indian ethnicities, longer T2DM duration, the use of pharmacological agents, and elevated blood pressure and lipid levels were associated with poor glycaemic control. The presence of comorbidities, pre-obesity and obesity were less likely to be associated with poor glycaemic control. 相似文献12.

INTRODUCTION
The aim of this study was to evaluate the health-related quality of life (HRQoL) of Malaysian patients with type 2 diabetes mellitus (T2DM) who have cardiovascular disease (CVD), as well as identify the determinants of HRQoL among this cohort of patients.METHODS
This study was an analytical cross-sectional study involving 313 patients aged 30–78 years (150 men, 163 women; mean age 55.7 ± 9.2 years) who were diagnosed with T2DM (mean duration of T2DM 10.1 ± 8.1 years) at two tertiary Malaysian government hospitals. The patients’ sociodemographic, lifestyle, clinical and laboratory data were collected prospectively from medical records and via face-to-face interviews. HRQoL was assessed using the 15D instrument – a generic, 15-dimensional and standardised measure of HRQoL that can be used as both a profile and a single index score measure.RESULTS
T2DM patients with CVD were found to have significantly lower 15D HRQoL scores than their non-CVD counterparts (p < 0.001). The HRQoL of T2DM patients with CVD was significantly lower than those without CVD (p < 0.05) in all of the 15 dimensions of the 15D instrument. Multinomial logistic regression analysis using backward stepwise method revealed a significant association between CVD and impaired HRQoL (odds ratio [OR] 11.746, 95% confidence interval [CI] 4.898–28.167). Age (OR 1.095, 95% CI 1.054–1.137), duration of T2DM (OR 1.085, 95% CI 1.032–1.140), ethnicity (OR 0.411, 95% CI 0.187–0.903), body mass index (OR 1.074, 95% CI 1.006–1.148), and physical activity level (OR 3.506, 95% CI 1.415–8.689) were also significant predictors of HRQoL.CONCLUSION
In T2DM patients, the presence of CVD was significantly associated with a lower HRQoL. Therefore, the importance of tertiary prevention to minimise the potential deterioration of the HRQoL of T2DM patients with CVD should be highly emphasised. 相似文献13.
INTRODUCTION
Intraoperative cell salvage (ICS) is an important aspect of patient blood management programmes. An ICS service was introduced at KK Women’s and Children’s Hospital, Singapore, from 2 May 2011 to 30 April 2013 to aid in the management of massive obstetric haemorrhage.METHODS
With support from the Ministry of Health’s Healthcare Quality Improvement and Innovation Fund, a workgroup comprising obstetricians, anaesthetists and nursing staff was formed to develop training requirements, clinical guidelines and protocols for implementing ICS using the Haemonetics Cell Saver 5. Pregnant women with an anticipated blood loss of > 1,000 mL during Caesarean delivery, a baseline haemoglobin level of < 10 g/dL, rare blood types and who had refused donor blood were recruited to the service after obtaining informed consent.RESULTS
A total of 11 women were recruited to the ICS service; the primary indications were placenta praevia and placenta accreta. Median blood loss in these 11 patients was 1,500 (range 400–3,000) mL. In four patients, adequate autologous blood was collected to initiate processing and salvaged, processed blood was successfully reinfused (mean 381.3 [range 223.0–700.0] mL). Median blood loss among these four patients was 2,000 (range 2,000–3,000) mL. No adverse event occurred following autologous transfusion. Mean immediate postoperative haemoglobin level was 8.0 (range 7.1–9.4) g/dL.CONCLUSION
The implementation of an obstetric ICS service in our institution was successful. Future studies should seek to address the cost-effectiveness of ICS in reducing allogeneic blood utilisation. 相似文献14.

INTRODUCTION
Postoperative nausea and vomiting (PONV), and postoperative pain are common during the early postoperative period. In addition to these problems, elderly patients risk developing postoperative confusion. This study aimed to identify the risk factors associated with these problems, and the extent of these problems, in a Singapore inpatient surgical population.METHODS
Over a period of six weeks, we surveyed 707 elective surgical inpatients aged ≥ 18 years who received general anaesthesia and/or regional anaesthesia.RESULTS
The incidence of PONV was 31.8%(95% confidence interval [CI] 34.8–41.9). The incidence increased with increasing Apfel score (p < 0.001) and were higher in female patients (odds ratio [OR] 1.74, 95% CI 1.28–2.36), non-smokers (OR 1.72, 95% CI 1.04–2.88), patients with a history of PONV and/or motion sickness (OR 3.45, 95% CI 2.38–5.24), patients who received opioids (OR 1.39, 95% CI 1.03–1.88), and patients who received general anaesthesia (OR 1.76, 95% CI 1.11–2.79). Moderate to severe pain at rest and with movement were reported in 19.9% and 52.5% of patients, respectively. Among the patients who were predicted to experience mild pain, 29.5% reported moderate pain and 8.1% reported severe pain. The prevalence of postoperative confusion was 3.9% in the geriatric population.CONCLUSION
Higher Apfel scores were associated with a higher risk of PONV and multimodal treatment for postoperative pain management was found to be insufficient. The incidence of postoperative confusion was low in this study. 相似文献15.

INTRODUCTION
The effects of reduction of left ventricular (LV) systemic afterload following aortic valve replacement (AVR) for severe aortic valve stenosis (AS) were investigated, using echocardiography and tissue Doppler imaging (TDI).METHODS
We compared the preoperative and postoperative echocardiographic assessments of 23 patients with severe AS who had undergone isolated AVR (n = 13) or concomitant AVR with coronary artery bypass grafting (CABG) (n = 10). Conventional echocardiographic evaluations and TDI at the lateral mitral annulus were performed.RESULTS
Echocardiography was performed at a median of 120 (interquartile range: 66–141) days after AVR. There was significant reduction in aortic transvalvular mean pressure gradient after AVR. Although LV dimensions, mass and ejection fraction remained unchanged, LV diastolic and systolic functions improved (as observed on TDI). Early diastolic (E’), late diastolic (A’) and systolic (S’) mitral annular velocities increased significantly (p < 0.05). There was significant improvement in TDI-derived parameters among the patients who had isolated AVR, while among the patients who had concomitant AVR with CABG, only S’ had significant improvement (p = 0.028).CONCLUSION
TDI was able to detect improvements in LV systolic and diastolic function after AVR for severe AS. There was less improvement in the TDI-derived diastolic parameters among patients who underwent concomitant AVR with CABG than among patients who underwent isolated AVR. 相似文献16.

INTRODUCTION
Granulomatous cervicofacial lymphadenitis (GCL) is not uncommon in children. Nontuberculous mycobacteria (NTM) seem to be the predominant cause. We sought to study the clinical and microbiological profile of patients with GCL, and identify features that may impact outcome.METHODS
Children aged < 16 years who presented to KK Women’s and Children’s Hospital, Singapore, between January 1998 and December 2006, and who had GCL were identified from laboratory records. Clinical and laboratory data was collected and analysed for risk factors for patients with positive lymph node cultures, and for patients with and without recurrence after treatment.RESULTS
In all, 60 children were identified, with a median age of 56 (interquartile range [IQR] 34–101) months. Median duration of symptoms before presentation was 5 (IQR 4–8) weeks. The majority presented with single (73.3%) or unilateral (96.7%) lymphadenopathy, located in the submandibular, preauricular/parotid or infra-/post-auricular region (76.7%). Out of 51 patients, 26 (51.0%) had a tuberculin skin test reading of ≥ 10 mm. Out of 52 patients, 10 (19.2%) had positive mycobacterial cultures, which included seven isolates of NTM. Out of 34 cases, tuberculous polymerase chain reaction was positive in 11 (32.4%). With regard to recurrence after initial treatment, age < 5 years at presentation was found to be a predictor for recurrence (p = 0.008), while initial complete excision of affected nodes predicted no recurrence (p = 0.003).CONCLUSION
In our study, younger age was noted to be associated with a higher chance of recurrence, while complete excision of the involved node at initial presentation predicted non-recurrence. 相似文献17.
INTRODUCTION
Teenage pregnancy is associated with poor neonatal outcomes, which may burden the young mothers and their families. The aim of this study was to determine the effect young maternal age and single motherhood has on neonatal outcomes.METHODS
We conducted a retrospective cohort study of 267 infants born to mothers aged ≤ 21 years in National University Hospital, Singapore, from January 2011 to December 2012. We compared the maternal demographics and neonatal outcomes of single mothers with those of married mothers. The neonatal outcomes of our study cohort were also compared to the hospital’s birth cohort during the same period.RESULTS
Unsatisfactory antenatal care was more prevalent among the young single mothers than among the young married mothers (odds ratio [OR] 2.90, 95% confidence interval [CI] 1.71–4.92, p < 0.01). The infants of the young single mothers had a lower mean birth weight (p = 0.01), with a significant proportion weighing < 2.5 kg (OR 2.91, 95% CI 1.35–6.37, p < 0.01). Young maternal age was linked to a higher incidence of prematurity (OR 1.70, 95% CI 1.18–2.43, p < 0.01), major congenital defects (OR 4.68, 95% CI 2.10–10.13, p < 0.01), and a perinatal mortality of 18.7 per 1,000 births (OR 3.76, 95% CI 1.26–10.32, p = 0.02).CONCLUSION
Young single mothers were more likely to have unsatisfactory antenatal care and lighter infants. Young maternal age was associated with a higher risk of prematurity, major congenital malformations and perinatal mortality. More studies are needed to ascertain the cause of these adverse outcomes. 相似文献18.

INTRODUCTION
Hip arthroplasty is commonly performed worldwide. The objective of this study was to determine the diameter of the femoral head in the Malaysian population in relation to gender and race (i.e. among Malay, Chinese and Indian patients).METHODS
This was a retrospective cross-sectional study performed between January 1995 and December 2006, evaluating the femoral head diameters of all patients aged 50 years and above who underwent hemiarthroplasty at two major hospitals in Malaysia.RESULTS
A total of 945 femoral heads (663 women, 282 men) were evaluated. The mean age of the patients in our cohort was 75.2 ± 9.4 (range 50–101) years. The mean femoral head diameter (with intact articular cartilage) was 44.9 ± 3.2 (range 38–54) mm. In our study, men had a significantly larger mean femoral head diameter than women (47.7 ± 2.8 mm vs. 43.7 ± 2.4 mm; p < 0.05). Patients of Chinese ethnicity were also found to have significantly larger femoral head diameters, when compared among the three races studied (p < 0.05).CONCLUSION
Malaysians have a mean femoral head diameter of 44.9 ± 3.2 mm. Among our patients, Chinese patients had a significantly larger femoral head size than Malay and Indian patients. We also found that, in our cohort, men had significantly larger femoral head diameters than women. 相似文献19.
INTRODUCTION
Microalbuminuria is an early sign of kidney damage. The prevalence of microalbuminuria in Singapore has been reported to be 36.0%–48.5%. However, the prevalence of microalbuminuria reported in these studies was determined with one urine sample using a qualitative urine test. The aim of this study was to determine the prevalence of micro- and macroalbuminuria using a more stringent criterion of two positive quantitative urine albumin-creatinine ratio (ACR) tests.METHODS
We conducted a cross-sectional study of patients with type 2 diabetes mellitus (T2DM) who were followed up at a primary care clinic in Singapore. Patients were diagnosed to have albuminuria if they had two positive ACR tests within a seven-month period.RESULTS
A total of 786 patients with T2DM met the study’s inclusion criteria. 55.7% were already on an angiotensin-converting enzyme inhibitor (ACEI) and/or angiotensin receptor blocker (ARB). The prevalence rates of micro- and macroalbuminuria were 14.2% and 5.7%, respectively. Patients with albuminuria were more likely to have hypertension (odds ratio [OR] 3.47, 95% confidence interval [CI] 1.55–7.80). Diabetics with poorer diabetic control (OR 1.88, 95% CI 1.26–2.79), and higher systolic (OR 1.69, 95% CI 1.14–2.49) and diastolic (OR 1.96, 95% CI, 1.20 to 3.22) blood pressures were more likely to have albuminuria.CONCLUSION
In the present study, the prevalence of microalbuminuria is significantly lower than that previously reported in Singapore. The presence of hypertension, poor diabetic control and suboptimal blood pressure control are possible risk factors for albuminuria in patients with T2DM. 相似文献20.
