Background
Many patients with primary hyperparathyroidism (PHPT) present with less severe biochemical parameters. The purpose of this study was to compare the presentation, operative findings, and outcomes of these patients with “mild” PHPT to patients with “overt” disease.Methods
A retrospective review of a prospectively collected parathyroid database was performed to identify cases of PHPT undergoing an initial neck operation. Patients were classified as mild when either the preoperative calcium or PTH was within the normal limits. Comparisons were made with the Student’s t test, Chi-squared test, or Wilcoxon rank-sum test where appropriate. Kaplan–Meier estimates were plotted for disease-free survival and compared by the log-rank test.Results
Of the 1,429 patients who met inclusion criteria, 1,049 were classified as overt and 388 (27.1 %) were mild. Within the mild group, 122 (31.4 %) presented with normocalcemic PHPT and 266 (68.6 %) had a normal PTH. The two groups had similar demographics and renal function. Interestingly, the mild group had more than double the rate of kidney stones (3.1 vs. 1.3 %, p = 0.02). The mild group was less likely to localize on sestamibi scan (62.4 vs. 78.7 %, p < 0.01). Intraoperatively, more mild patients exhibited multigland disease (34.3 vs. 14.1 %, p < 0.01). When examining intraoperative PTH (IoPTH) kinetics where single adenomas were excised, the IoPTH fell at a rate of 6.9 pg/min in mild patients compared with 11.5 pg/min in the overt group (p < 0.01). Accordingly, 62.2 % of patients in the overt group and 53.3 % in the mild group were cured at 5 min postexcision (p < 0.01). There was no difference in the rates of persistence or recurrence between the groups, and disease-free survival estimates were identical (p = 0.27).Conclusions
Patients with mild PHPT were more likely to have multigland disease and a slower decline in IoPTH, but these patients can be successfully treated with surgery. 相似文献992.

Osteoporosis is frequently seen in patients with chronic obstructive pulmonary disease (COPD). Because research on bone structure and bone strength in COPD patients is limited, the objectives of this pilot study were as follows: (1) to compare bone structure, stiffness, and failure load, measured at the peripheral skeleton, between men with and without COPD after stratification for areal bone mineral density (aBMD); and (2) to relate clinical parameters with bone stiffness and failure load in men with COPD. We included 30 men with COPD (normal aBMD, n = 18; osteoporosis, n = 12) and 17 men without COPD (normal aBMD, n = 9; osteoporosis, n = 8). We assessed pack‐years of smoking, body mass index (BMI), fat free mass index (FFMI), pulmonary function (forced expiratory volume in 1 second [FEV1], FEV1/forced vital capacity [FVC], diffusion capacity for carbon monoxide [DLCO], and transfer coefficient for carbon monoxide [KCO]), and extent of emphysema. Bone structure of the distal radius and tibia was assessed by high‐resolution peripheral quantitative computed tomography (HR‐pQCT), and bone stiffness and failure load of the distal radius and tibia were estimated from micro finite element analysis (µFEA). After stratification for aBMD and COPD, men with osteoporosis showed abnormal bone structure (p < 0.01), lower bone stiffness (p < 0.01), and lower failure load (p < 0.01) compared with men with normal aBMD, and men with COPD had comparable bone structure, stiffness, and failure load compared with men without COPD. In men with COPD, lower FFMI was related with lower bone stiffness, and failure load of the radius and tibia and lower DLCO and KCO were related with lower bone stiffness and failure load of the tibia after normalization with respect to femoral neck aBMD. Thus, this pilot study could not detect differences in bone structure, stiffness, and failure load between men with and without COPD after stratification for aBMD. FFMI and gas transfer capacity of the lung were significantly related with bone stiffness and failure load in men with COPD after normalization with respect to femoral neck aBMD. © 2013 American Society for Bone and Mineral Research. 相似文献

INTRODUCTION
The aim of this study was to establish the incidence of post-operative venous thromboembolism (VTE) following varicose vein treatment.METHODS
Hospital Episode Statistics (HES) data were obtained for all patients undergoing varicose vein treatment between April 2006 and April 2007 to identify those reattending with either deep vein thrombosis or pulmonary embolism within 12 months.RESULTS
The incidence of VTE was 0.51%, which was comparable with the incidence for those undergoing open surgery (0.54%), sclerotherapy (0.19%) and endovenous laser therapy (EVLT) (0.47%). The incidence of VTE in those undergoing combined EVLT and phlebectomy was 1.26% (p=0.01). In contrast to unilateral treatment (all modalities), where bilateral treatment was performed an increase in the incidence of VTE was seen in those undergoing redo (1.62%) and short saphenous system (1.16%) treatments.Overall, 1.02% of cases were performed under local anaesthesia with zero incidence of VTE in this cohort.CONCLUSIONS
The overall incidence of VTE recorded in HES was 0.51% and appears to be highest in those undergoing bilateral redo or short saphenous system surgery as well as those undergoing a combination of EVLT and phlebectomy. The use of VTE prophylaxis, particularly in these groups, is recommended. 相似文献998.

Introduction
Although conventional multiport laparoscopic appendicectomy (CMLA) is preferred for managing acute appendicitis, the recently developed transumbilical laparoscopic approach is rapidly gaining popularity. However, its wide dissemination seems restricted by technical/technological issues. In this regard, a newly developed method of single site multiport umbilical laparoscopic appendicectomy (SMULA) was compared prospectively with CMLA to assess the former’s efficacy and the technical advantages in acute scenarios.Methods
Overall, 430 patients were studied: 212 in the SMULA group and 218 in the CMLA group. The same surgeon performed all the procedures using routine laparoscopic instruments. The SMULA technique entailed three ports inserted directly at the umbilical mound through three distinct strategically placed mini-incisions without raising the umbilical flap. The CMLA involved the traditional three-port technique.Results
Both groups were comparable in terms of demographic criteria, indications for surgery, intraoperative blood loss, time to ambulation, length of hospital stay and umbilical morbidity. Although the mean operative time was marginally longer in the SMULA group (43.35 minutes, standard deviation [SD]: 21.16 minutes) than in the CMLA group (42.28 minutes, SD: 21.41 minutes), this did not reach statistical significance. Conversely, the mean pain scores on day 0 and the cosmetic outcomes differed significantly and favoured the SMULA technique. None of the patients developed port site hernias over the follow-up period (mean 2.9 years).Conclusions
The favourable outcomes for the SMULA technique are likely to be due to the three small segregated incisions at one place and better trocar ergonomics. The SMULA technique is safe in an acute setting and may be considered of value among the options for transumbilical appendicectomy. 相似文献1000.
