Nicotine dependence and its familial aggregation in Chinese.

BACKGROUND: Nicotine dependence is a significant public health problem. This study attempted to characterize the prevalence and familial aggregation of nicotine dependence in China. METHODS: In 1998, we initiated a community-based cross-sectional study among residents of the Yuexi County in Anqing, China. A total of 991 current smokers from 488 randomly selected nuclear families were recruited and surveyed by use of the standardized Fagerstrom Test of Nicotine Dependence (FTND) questionnaire and the Revised Tolerance Questionnaire (RTQ). All study subjects were offspring in their respective nuclear families, and 478 male-male pairs (aged 41.7 +/- 12.1 years) were finally used for data analyses, because the number of female current smokers (n = 5) was too small. RESULTS: The correlation coefficient of the FTND and the RTQ scores was as high as 0.84 (P < 0.0001). Nicotine dependence, defined as an FTND score > or =8 or an RTQ score > or =28, had a prevalence of 12.7% and 11.1%, respectively. The respective sibling recurrent risk was 1.7 and 2.4, according to the FTND or the RTQ criteria. The adjusted odds ratios and 95% CI of nicotine dependence of second siblings in families in which the first sibling was nicotine dependent were 2.13 (95% CI: 1.02-4.43) and 3.50 (95% CI: 1.65-7.36) respectively, according to the FTND and RTQ criteria. CONCLUSIONS: The prevalence of nicotine dependence in male current smokers in China was comparable to that reported in previous US and European studies. Our findings suggest that genetic influences may play an important role in vulnerability to nicotine addiction.

Pathologic fractures of the proximal femur secondary to benign bone tumors.

Pathologic fractures of the proximal femur secondary to benign bone tumors often are difficult to treat because of specific anatomic features of this region and the aggressiveness of the tumors. Between 1986 and 1996, 11 patients presented with a pathologic fracture of the proximal femur secondary to a benign bone tumor. All were treated with a uniform approach consisting of biopsy, intralesional curettage, high-speed burring, and reconstruction using morselized allograft, autograft, and a fixed-angle implant. The average followup was 4 years 3 months (range, 24-114 months). One patient was lost to followup. All fractures healed, and there were no local recurrences and no cases of avascular necrosis. Functional evaluation revealed generally good results. Patients scored a mean of 32.6 on the original Musculoskeletal Tumor Society scale and 95.8 on the revised version. The average Toronto Extremity Salvage Score was 91.3. With the numbers available, there were no significant differences between the study group and population norms in the Short Form-36. These results suggest that a uniform approach based on preservation of the femoral head can be applied successfully to the treatment of these lesions with good local tumor control, fracture healing, and acceptable functional outcomes.

Comparison of OP-1 Putty (rhBMP-7) to iliac crest autograft for posterolateral lumbar arthrodesis: a minimum 2-year follow-up pilot study.

STUDY DESIGN: A prospective, randomized, controlled, multicenter clinical study. OBJECTIVE: To compare the safety and clinical and radiographic outcomes of OP-1 (BMP-7) Putty to autogenous iliac crest bone graft in a population of patients undergoing laminectomy and posterolateral fusion for symptomatic lumbar stenosis associated with degenerative spondylolisthesis. SUMMARY OF BACKGROUND DATA: Although the existing preclinical and clinical data suggest that OP-1 is able to achieve osteoinduction and clinical fusion in a variety of situations, the efficacy of this recombinant protein in a clinical spine fusion population has not been fully elucidated. This study directly compares the efficacy and safety of OP-1 putty to autograft bone for arthrodesis in patients with symptomatic stenosis in association with degenerative spondylolisthesis. METHODS: Thirty-six patients with degenerative lumbar spondylolisthesis and symptoms of neurogenic claudication underwent laminectomy, bilateral medial facetectomy, and posterolateral fusion using either iliac crest autograft or OP-1 Putty. Oswestry scores and SF-36 questionnaires were used to determine the clinical response to treatment. Independent, blinded neuroradiologists reviewed both static and dynamic radiographs to determine the fusion status. Successful fusion was declared whenthe presence of continuous bridging bone between the transverse processes was observed and less than 5 degrees of angular motion and 2 mm of translational movement was measured using digital calipers. RESULTS: Efficacy data were tabulated for 27 patients at the 24-month time point and an additional 4 patients (without evaluable 24-month results) at the 36-month time point. One patient was not evaluable for radiology, so the data reflect clinical information for 31 patients and radiology for 30 patients. Clinical success, defined as a 20% improvement in the preoperative Oswestry score, was achieved by 17 of 20 (85%) OP-1 Putty patients and 7 of 11 (64%) autograft patients. A successful posterolateral fusion was achieved in 11 of 20 (55%) OP-1 Putty patients and 4 of 10 (40%) autograft patients. SF-36 scores showed similar clinical improvement in both groups. No systemic toxicity, ectopic bone formation, recurrent stenosis, or other adverse events specifically related to the use of the OP-1 Putty implant were observed. CONCLUSION: This study represents the first clinical trial to demonstrate the safety and similarity of OP-1 Putty as a replacement for autogenous bone graft in the posterolateral fusion environment with a minimum of 2-year follow-up. OP-1 Putty was able to achieve osteoinduction leading to a radiographically solid fusion in the absence of autogenous iliac crest bone graft in 55% of the patients at 24 and 36 months. These results compare favorably to the historical fusion rates reported for uninstrumented arthrodesis in this challenging clinical scenario.

Cumulative incidence of achilles tendon rupture and tendinopathy in male former elite athletes.

OBJECTIVE: To study the cumulative incidence of Achilles tendon rupture and tendinopathy among former top-level athletes. DESIGN: Historical cohort study. SETTING: Finland. PARTICIPANTS: Male former elite athlete cohort members (n = 785; median age, 69 years when responding to the questionnaire; range, 54-97) and their matched controls (n = 416; median age, 68 years; range, 56-94). OUTCOME MEASUREMENTS: Questionnaire-reported Achilles tendinopathy and tendon rupture diagnosed by physicians before the age of 45 years and within the subjects' lifetimes. RESULTS: Cumulative incidence of Achilles tendinopathy before the age of 45 was high for middle and long-distance runners (adjusted odds ratio, 31.2 compared with controls; P < 0.001), and cumulative incidence of Achilles tendon rupture was high for sprinters (odds ratio, 14.9; P < 0.001). CONCLUSIONS: Achilles tendon problems seem to constitute clinically significant and common problems in specific sports.

Injury type, injury severity, and repeat occurrence of alcohol-related trauma in adolescents.

Injury associated with alcohol use is a significant problem among adolescents; however, routine evaluation of alcohol use in this population is not conducted. The purpose of this study was to compare injured adolescents presenting to an emergency room with a positive serum alcohol concentration (SAC+) with those injured adolescents with a negative serum alcohol concentration (SAC-). Data were collected retrospectively on 176 injured patients, between the ages of 13 and 18, consecutively admitted to a university hospital from January 1, 1989-December 31, 1990. Information collected included mechanism and severity of injury, outcome, SAC, length of stay, psychiatric history, prior or subsequent admission for injury, and hospital charges. Of those tested with an SAC, more than one-third had a positive SAC. Patients with positive SACs had a greater probability of having a psychiatric history and more frequently had a prior or subsequent injury. Furthermore, only 34% of SAC+ patients were referred for counseling. The results indicate that a SAC should be obtained on all adolescents admitted for trauma, that adolescents presenting with injuries and a positive SAC should be referred for alcohol and psychiatric assessment, and that injured adolescents may be at increased risk for repeat injuries in the future.

Relationship between pre-TIPS liver perfusion by the portal vein and the incidence of post-TIPS chronic hepatic encephalopathy.

OBJECTIVE: In the present study we evaluated the predictive value of pretransjugular intrahepatic portosystemic shunt (TIPS) portal perfusion as assessed by Doppler ultrasonography for the onset of chronic encephalopathy after TIPS. METHODS: A total of 231 cirrhotic patients were followed-up prospectively after TIPS placement. The pattern of intrahepatic portal flow was assessed before TIPS. Patients were divided into two groups according to Doppler findings. Group 1 comprised patients with prograde portal flow (n = 200), whereas group 2 comprised those with loss of portal perfusion (hepatofugal or back-and-forth flow or portal vein thrombosis; n = 31). The presence of chronic encephalopathy during a median follow-up of 32 months was prospectively recorded. The prognostic value of the following parameters for the onset of chronic recurrent encephalopathy after TIPS was evaluated: age, presence of encephalopathy before TIPS, alcoholism, Pugh score, and loss of portal perfusion before TIPS. The independent prognostic value of each variable was tested with a multiple logistic regression analysis. RESULTS: The two groups were comparable in terms of age, incidence of prior episodes of hepatic encephalopathy, and portacaval gradient before and after the procedure; however, liver failure was more severe in patients in group 2 (Pugh score: 9.2 +/- 1.9 vs 10.3 +/- 1.7). The 3-yr survival was identical for both groups; 25% of the 200 patients in group 1 developed chronic encephalopathy as compared to 6% of the 31 patients in group 2 (p = 0.03). Multiple logistic regression analysis demonstrated that loss of portal perfusion and age >65 yr were the only independent predictors of the onset of post-TIPS chronic encephalopathy (odds ratios 0.24 and 1.98, respectively). CONCLUSIONS: Cirrhotic patients with loss of portal perfusion before TIPS were protected against post-TIPS chronic hepatic encephalopathy despite a more severe liver dysfunction at baseline. The only other independent predictive factor for the onset of this complication was age.

A prospective, randomized, controlled trial of covered expandable metal stents in the palliation of malignant esophageal obstruction at the gastroesophageal junction.

OBJECTIVE: Palliation of malignant esophageal obstruction is an important clinical problem. Expandable metal stents are a major advance in therapy, but many stents become obstructed because of tumor ingrowth. The aim of this study was to compare a new, membrane-covered expandable metal stent to conventional prostheses in a randomized controlled trial. METHODS: Sixty-two patients with malignant inoperable esophageal obstruction at the gastroesophageal junction participated in the study. Patients were randomly assigned to covered or uncovered stents. The principal outcome measure was the need for reintervention because of recurrent dysphagia or migration. Secondary endpoints were relief of dysphagia measured by a dysphagia score (grade 0 = no dysphagia, grade 1 = able to eat solid food, grade 2 = semisolids only, grade 3 = liquids only, grade 4 = complete dysphagia) and the rate of complications and functional status. All patients were observed at monthly intervals until death or for 6 months. RESULTS: One week after stenting the dysphagia score improved significantly in both the uncovered (n = 32, 3 +/- 0.1 to 1 +/- 0.1 [means +/- SEMs], p < 0.001) and covered (n = 30, 3 +/- 0.1 to 1 +/- 0.2 [means +/- SEMs], p < 0.001) stents. Obstructing tumor ingrowth was significantly more likely in the uncovered stent group (9/30) than in the covered group (1/32) (p = 0.005). Significant stent migration occurred in 2/30 patients with uncovered stents, as compared with 4/32 patients in the covered group (p = 0.44). Reinterventions for tumor ingrowth were significantly greater in the uncovered stent group (27%), as compared with 0% in the covered group (p = 0.002). Life table analysis showed similar survival in both groups. CONCLUSION: Membrane-covered stents have significantly better palliation than conventional bare metal stents because of decreased rates of tumor ingrowth that necessitate endoscopic reintervention for dysphagia.

Pneumatic dilation for achalasia: late results of a prospective follow up investigation.

BACKGROUND: and aims: In this prospective study, we determined the long term clinical course of patients with achalasia who were treated by pneumatic dilation using the Browne-McHardy dilator, and determined whether previously described predictors of outcome remain significant after prolonged follow up. METHODS: Between 1981 and 1991, 54 consecutive patients were treated by pneumatic dilation and followed up at regular intervals for a median of 13.8 years. Remission was determined with the use of a structured interview and a previously described symptom score. Duration of remission was evaluated by Kaplan-Meier estimates of time to recurrence. Predictors of outcome were determined using the log rank test. RESULTS: Complete follow up until 2002 was obtained in 98% of all patients. Seven patients had died and were censored. A single pneumatic dilation resulted in a five year remission rate of 40% and a 10 year remission rate of 36%. Repeated dilations only mildly improved the clinical response. Patients who were older than 40 years had a significantly better outcome than younger patients (log rank test, p = 0.0014). However, the most significant predictive factor for a favourable long term outcome was a post-dilation lower oesophageal sphincter pressure of less than 10 mm Hg (log rank test, p = 0.0001). CONCLUSIONS: Long term results of pneumatic dilation are less favourable than previously thought. Young patients and those not responding to a single pneumatic dilation should be offered alternative therapy. Patients who remain in remission for five years are likely to benefit from the longlasting treatment effect of pneumatic dilation.

Prostatic intraepithelial neoplasia: A marker for high-risk groups and a potential target for chemoprevention.

Both the incidence of, and the mortality due to, prostate cancer in the USA are higher in African-American men than in Caucasian men. This is particularly true in men less than 60 years of age. Our findings indicate that both the prevalence and the extensiveness of high-grade prostatic intraepithelial neoplasia (PIN) are higher in African-American men compared to Caucasians and that this discrepancy starts as early as the third decade of life. In an autopsy series comprising 650 men, extensive high-grade PIN with diffuse involvement of the prostate gland was evident in 25 (7%) of 364 African-American men less than 50 years of age compared to 4 (2%) of 208 Caucasian men in the same age group (p = 0.002). In a series of more than 1,200 men undergoing radical prostatectomy for clinically localized prostate cancer, extensive high-grade PIN was significantly and consistently higher in the African-American cohort than the Caucasian cohort. The difference was more evident in younger patients and those with smaller, organ-confined tumors. In a subset of 216 men (71 African-Americans and 138 Caucasians) with clinical stage T1C prostate cancer, extensive high-grade PIN was identified in 33% and 12% of the two groups respectively (p = 0.001). Moreover, in patients with organ-confined disease, both Gleason score and the extensiveness of high-grade PIN were significant predictors of biochemical recurrence. Our findings suggest an important role for high-grade PIN in the development of clinically significant, potentially aggressive prostate cancer in African-American men. In this epidemiologically identifiable high-risk group, there is a potential opportunity for chemoprevention strategies in younger men with high-grade PIN.

Thymidylate synthase protein expression in advanced colon cancer: correlation with the site of metastasis and the clinical response to leucovorin-modulated bolus 5-fluorouracil.

Recently, we have demonstrated that thymidylate synthase (TS) protein expression predicts for the clinical response to a regimen of infusional 5-fluorouracil (5FU) in advanced colorectal cancer patients. Previous studies by other groups that showed a correlation between TS gene expression and response to the fluoropyrimidine also involved infusional regimens. Considering the putatively different mechanism of action of bolus compared with continuous infusion of 5FU, the aim of the present study was to test whether the correlation between TS expression and the clinical response to 5FU is valid for bolus regimens. A secondary aim was to compare TS levels between liver metastases and abdominal recurrences from colon cancer, because these sites have a distinctly different responsiveness to 5FU chemotherapy. The study population consisted of 41 patients (25 males and 16 females; median age, 60 years) with unresectable metastatic or recurrent colon cancer, homogeneously treated with 5FU (420 mg/m2 i.v., days 1-5) and leucovorin (20 mg/m2 i.v., days 1-5); cycles were repeated every 28 days. Twenty-seven patients (66%) showed high levels of TS expression as defined by TS scores equal to 3 and 4. The proportion of cases with high levels of TS expression was significantly higher in abdominal recurrences (18 of 22, 82%) compared with liver metastases (9 of 19, 47%; P = 0.02). Intratumoral TS protein expression was inversely correlated with response to chemotherapy (response rate: 7 of 14, 50%, versus 0 of 27 in patients with low and high levels of TS expression, respectively; P = 0.0001). These results confirm that the level of TS protein expression predicts for response to 5FU, even with a bolus schedule. The higher TS levels observed in abdominal compared with liver metastases may account for their different responsiveness to 5FU chemotherapy. Immunohistochemical quantitation of TS protein levels may thus allow us to change the therapeutic approach to advanced colorectal cancer from a general to an individual treatment strategy at a time when new non TS-targeted drugs have become available for this disease.

Stapled hemorrhoidectomy: surgical notes and results.

Recently the surgical treatment of hemorrhoids using a circular stapler device has gained increasing approval. The Longo's procedure reduces the rectal mucosal and hemorrhoid prolapse using a circular stapler to resect transversally a mucosal-submucosal rectal ring in order to restore the correct anatomical relationships of the anal canal structures. The recent availability of a dedicated instrument kit (PPH01 Ethicon Endo-Surgery) allowed an easy diffusion of this technique. From March 1999 to September 2001, 198 patients with III-IV degree hemorrhoids were treated by a single expert surgeon using the dedicated kit instrumentation (PPH01) according to the Longo's technique, adopting some variations from the original procedure: 1) The anal dilator is not fixed to the perianal skin with forceps or stitches but is kept by the assistant. 2) In performing the purse-string suture particular care must be given to the apposition of the stitches at the same level also in the posterolateral side where there is a natural trend to apply the stitches at a lower level; furthermore the last stitch of the purse-string suture must be overlapped to the first one in order to allow a better hemostasis when the knot is tightened. 3) After having performed the purse-string and having resected the mucosa and submucosa, an accurate hemostasis with U-shaped 3/0 vicryl stitches firmly reduces the postoperative bleeding. We recorded pain scores, short- and long-term complications (included moderate-severe pain, persistent pain), recurrences and postoperative hospital stay. The data of the last 40 consecutive patients who underwent stapled hemorrhoidectomy were compared with the data obtained by 40 consecutive patients who underwent Milligan-Morgan diathermic hemorrhoidectomy for III-IV degree non-circumferential hemorrhoids by the same surgeon. In the 198 stapled hemorrhoidectomy cases the rate of postoperative moderate-severe pain and persistent pain were 6% and 2.5% respectively, the rate of short-term and long-term bleeding were 4.5% and 3.5%, the recurrence rate was 2.5%. The mean postoperative stay was 1.6 days. The stapled group had significantly lower postoperative moderate-severe pain, bleeding and soiling than the Milligan-Morgan group.

[Cerebral arterial dissection].

We investigated a total of 98 cases with stroke caused by cerebral arterial dissection recruited in Strategies against Stroke Study for Young Adults in Japan (SASSY-Japan). The most frequent site of dissection was the intracranial vertebrobasilar artery. The stroke subtype was divided into ischemic (TIA and cerebral infarction) and hemorrhagic types (subarachnoid hemorrhage). The ischemic type was predominant (69%) and patients with the ischemic type were younger than those with the hemorrhagic type (P < 0.01). In the intracranial arterial dissection, nearly all cases were of the ischemic type. In contrast, in the extracranial arterial dissection, 60% of cases were ischemic and 40% were hemorrhagic. Cerebral angiography was the most important diagnostic procedure in the hemorrhagic type. In the ischemic type, MRI and MRA were more frequently used to show the findings specific to the dissection such as an intimal flap or double lumen and intramural hematoma. The outcome at discharge is generally good such that the modified Rankin Score was among 0-II in 69% of cases. However, in the hemorrhagic type, recurrence during an acute stage was frequent, and the outcome was poor with a mortalit rate of 19%. The establishment of an effective intervention to prevent the recurrence of subarachnoid hemorrhage is urgently required.

[Clinical study on effect of xiongshao capsule on restenosis after percutaneous coronary intervention].

OBJECTIVE: To further evaluate the effect of Xiongshao Capsule (XSC) on the restenosis (RS) after percutaneous coronary intervention (PCI), based on previous clinical trials by which the preventive effect of XSC on RS after PCI has been proved. METHODS: Adopting the randomized, double-blind and placebo controlled method, the 124 patients enrolled, who were patients with coronary artery disease and received intracoronary stenting, were randomly assigned into two groups, the XSC group and the placebo control group, with 62 in each group. Six months of follow-up study was carried out on them to observe the intervention effect of XSC, which was predominantly evaluated by RS rate estimated by coronary angiography (CAG), combined with the recurrent rate of angina, clinical end-point event, and blood-stasis syndrome scores. RESULTS: Sixty two cases of 118 effective patients were followed-up with CAG for 6 months, the follow-up rate was 52.5%. The incidence of RS in the XSC group and the control group was 24.1% and 48.5% respectively, and the incidence of RS in stent in them was 14.0% and 42.0% respectively, indicating that the incidence of RS rate in the XSC group was significantly lower than that in the control group (P < 0.05). After patients had been treated for 6 months the extent of angiostenosis and diameter of the culprit arteries, determined by CAG was 26.58 +/- 20.72% and 2.21 +/- 0.85 mm in the XSC group, and 41.19 +/- 30.92% and 1.72 +/- 0.99 mm in the control group, respectively, suggesting that the extent of angiostenosis and the diameter loss were significantly reduced in the former than those in the latter, respectively (P < 0.05). The incidence of clinical end-point event was 11.7% and 27.6% in the XSC group and the control group in the 6 months' follow-up period respectively, it was significantly lower in the XSC group than that in the control group, with the P value close to statistical significance (P = 0.051). The blood-stasis syndrome scores in the XSC group was significantly lower in comparing with that in the control group after 6 months' treatment (P < 0.01). CONCLUSION: XSC can effectively prevent RS after PCI in combination with conventional Western medical treatment.

[Luteinized unruptured follicle syndrome].

In a group of 109 infertile women, 180 cycles were monitored with B type ultrasound, BBT and cervical scoring. The incidence of LUF in stimulated cycles was 31.8%, significantly higher than that in spontaneous cycles (10.1%). During the follicular phase, no difference was found between the LUFS and normal ovulatory cycles as to follicular growth curve, maximal diameter of dominant follicle and the cervical scores. Therefore prediction of the LUFS is difficult. 63.6% of the LUF patients had recurrences, and high incidence of abnormality (70.6%) in their non-LUF cycles. 7 of the 14 patients with LUFS were originally diagnosed as unexplained infertility. It suggests that LUFS is of particular importance in the group of women with unexplained infertility.

Structural allograft in two-stage revisions for failed septic hip arthroplasty.

We report 11 patients having revision of total hip arthroplasty using massive structural allografts for failure due to sepsis and associated bone loss. All patients had a two-stage reconstruction and the mean follow-up was 47.8 months (24 to 72). Positive cultures were obtained at the first stage in nine of the 11 patients, with Staphylococcus epidermidis being the most common organism. The other two patients had draining sinuses with negative cultures. There was no recurrence of infection in any patient. The mean increase in the modified Harris hip score was 45 and all the grafts appeared to have united to host bone. Two patients required additional procedures, but only one was related to the allograft. Complications included an incomplete sciatic nerve palsy and one case of graft resorption. Our results support the use of massive allografts in failed septic hip arthroplasty in which there is associated bone loss.

Usefulness of echocardiography in the prognostic evaluation of non-Q-wave myocardial infarction.

Patients with non-Q-wave myocardial infarction (MI) are a heterogeneous population with a wide range of coronary disease severity and extent of myocardial necrosis, showing, therefore, different electrocardiographic findings and different outcomes. To evaluate the role of echocardiography in the management of non-Q-wave MI patients, 192 consecutive patients without previous MI were studied (78 with ST segment elevation, 56 with ST depression and 58 without ST modifications). All patients underwent 2-dimensional echocardiography (16-segment model) within 24 hours of admission to the coronary care unit. Wall-motion abnormalities, wall-motion score index, ejection fraction, and end-diastolic and end-systolic volumes were evaluated. In 35 patients, death, reinfarction, recurrent angina, or severe heart failure occurred during the in-hospital phase, whereas the remaining 157 patients had a good outcome. Patients with a poor prognosis were older (68 +/- 6 vs 59 +/- 5 years, p < 0.01), had a worse left-ventricular function (wall-motion score index 1.4 +/- 0.4 vs 1.25 +/- 0.3, p < 0.05; end-systolic volume 54 +/- 25 vs 38 +/- 12 mL/m2, p < 0.01; ejection fraction 50 +/- 10 vs 58 +/- 8%, p < 0.01), and presented more frequently with ST segment depression (49 vs 25%, p < 0.01). The positive and negative predictive values for early clinical events were, respectively: ST segment depression 0.30 and 0.87; wall-motion abnormalities in > 3 segments 0.28 and 0.86; wall-motion score index > 1.33 = 0.28 and 0.87; end-diastolic volume > 46 mL/m2 = 0.49 and 0.91; ST segment depression and wall-motion abnormalities in > 3 segments 0.60 and 0.88. These results underline the usefulness of echocardiography in the early risk stratification of non-Q-wave MI patients, together with electrocardiographic data. Patients with ST segment depression and more extensive wall-motion abnormalities are at higher risk and their management needs a more aggressive approach.

Voice and swallowing changes after thyroidectomy in patients without inferior laryngeal nerve injuries.

BACKGROUND: We performed a prospective analysis on voice and swallowing alterations following total thyroidectomy (TT), in the absence of recurrent nerve injury. METHODS: Patients aged 21 to 65 years undergoing TT, in the absence of laryngeal/pulmonary disease, previous neck surgery, or malignant diseases, were subjected to videostrobolaryngoscopy (VSL), acoustic voice analysis (AVA), and maximum phonation time (MPT) tests preoperatively and 3 months postoperatively. Voice impairment scores (VIS) and swallowing impairment scores (SIS) were obtained preoperatively, and at 1 week, 1 month, and 3 months postoperatively. RESULTS: Among the 127 selected patients, 39 completed the postoperative evaluation. No recurrent nerve injury was observed during the postoperative VSL in any of the patients. Preoperative and postoperative AVA and MPT scores did not differ significantly. The mean postoperative VIS was significantly higher than the preoperative VIS at 1 week and 1 month after TT (13.7 and 9.6 vs 4.4, respectively; P < .05) but not 3 months after TT (6.7). The mean SIS was higher than the preoperative SIS at 1 week, 1 month, and 3 months after TT (10.3, 6.0, and 2.8 vs 0.5, respectively; P < .05). CONCLUSIONS: Physicians should inform patients that transient voice and swallowing symptoms may occur following total thyroidectomy, and our data suggest mild symptoms may occur in the majority of operated patients.
