Severe postpartum disruption of the pelvic ring: report of two cases and review of the literature

Background

Intra-articular hardware penetration can occur during osteosynthesis of ankle fractures, jeopardizing patients' outcomes. The intraoperative recognition of misplaced screws may be difficult due to the challenge of adequate interpretation of specific radiographic views. The present study was designed to investigate the diagnostic accuracy of standardized radiographic ankle views to determine the accuracy of diagnosis for intra-articular hardware placement of medial malleolar screws in a cadaveric model.

Methods

Nine preserved human cadaveric lower extremity specimens were used. Under direct visualization, two 4.0 mm cancellous screws were inserted into the medial malleolus. Each specimen was analyzed radiographically using antero-posterior (AP) and mortise views. The X-rays were randomly uploaded on a CD-ROM and included in a survey submitted to ten selected orthopaedic surgeons. The "Standards for Reporting of Diagnostic Accuracy" (STARD) questionnaire was used to determine the surgeons' perception of accuracy of screw placement in the medial malleolus. The selection of items was based on evidence whenever possible, therefore the "inconclusive" category was added. Inter and intraobserver variations were analyzed by kappa statistics to measure the amount of agreement.

Results

There was a poor level of agreement (kappa 0.4) both in the AP and in the mortise view among all the examiners. Associating the two x-rays, the agreement remained poor (kappa 0.4). In the cases in which there was a diagnosis of articular penetration, there was a poor agreement related to which of the screws was intra-articular. The number of "inconclusive" responses was low and constant, without a statistically significant difference between the subspecialists

Conclusion

The routine intraoperative radiographic imaging of the ankle is difficult to interpret and unreliable for detection of intra-articular hardware penetration. We therefore recommend to reposition medial malleolar screws intraoperatively if there is any doubt regarding inadequate screw placement.     

Does the complication rate and treatment effect of balloon kyphoplasty and vertebroplasty differ in countries or specialties of operators?

Purpose

Vertebral compression fracture results in back pain, kyphotic deformity, loss of vertebral height, and restriction in daily activity. Conservative treatment, including analgesics, bed rest, and bracing, did not show up for good clinical control. Recently, minimally invasive surgical techniques, such as kyphoplasty and vertebroplasty, could become popular because of quick relief of pain. The goal of this review is to find out whether the complication rates and treatment effects differ in countries or specialties of operators.

Materials and Methods

Detailed searches of electronic databases (i.e. Pubmed, Cochrane library) were performed from 1987 to April 2007. Outcome measures of efficacy included visual analog scale decrease, change in kyphotic angle, restoration of vertebral height, and improvement of functional capacity. Outcome measures of safety were cement leakage, new vertebral compression fracture, and complications.

Results

There is a trend of increasing publications regarding these two procedures, especially in vertebroplasty. We found a higher level of cement leakage rate in vertebroplasty than in kyphoplasty. We also found that reduction in kyphotic angle was better in kyphoplasty than in vertebroplasty. These results were compatible with other literatures. Cement leakage rates were lower in neurosurgery department (20.6%) and orthopedic department (24.7%) than radiology department (52.9%).

Conclusions

The procedure operated by orthopedic surgeons and neurosurgeons tend to have lower cement leakage rate. One possible reason was that the neurosurgeons and the orthopedic surgeons are more familiar with the anatomical information needed for the procedure. Another possible explanation was that the radiologists might have more sufficient data to report the complications than the clinicians.     

Cystic lymphatic malformation of bladder presenting as a pelvic mass

We report a 5-year-old boy with a cystic lymphatic malformation (LM) of bladder, and the imaging characteristics of the lesion are reported. Cystic LM of the urinary system is rare, and a location in the bladder is extremely rare. The exact mechanism of the lesion that occurs in bladder is unknown. This case is different from the 3 cases reported before, for it is only presented with a palpable pelvic mass and the lesion did not penetrate full thickness of bladder. Although imaging examinations are helpful in the definition of cystic LMs, no characteristic findings are available to diagnose a cystic LM of the bladder before surgery. The diagnosis is always made after surgical intervention. Surgical excision is ideal, and an extensive operation is not warranted because the lesion is benign. Once excised completely, the prognosis of the disease is good.     

Optimum initial dose of silodosin for treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia

We investigated the optimum initial dose and timing of administration of α1A-adrenoceptor antagonist silodosin for treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH/LUTS). Ninety-eight patients were given a 4 mg dose after breakfast (group A), 4 mg after supper (group B), or 4 mg after breakfast and after supper (group C). At baseline, 4, 8 and 12 weeks after treatment, we assessed International Prostate Symptom Score (IPSS) and quality of life (QOL) index. Twenty-five percent or less improvement of total IPSS and no improvement of QOL index compared with baseline were defined as treatment failure at each evaluation point. Otherwise treatment was considered effective. In group A and group B, patients with treatment failure at 4 or 8 weeks after treatment, the dose of silodosin was increased to 8 mg daily. At the end of the study, 83 patients were evaluable. At 12 weeks after treatment, 20 of the 31 patients in group A and 22 of the 29 patients in group B remained on the 4 mg dose ; silodosin was effective in 65 and 76% of the patients, respectively. When patients with dose escalation were included, silodosin was effective in 81 and 90% of the patients, respectively. Silodosin was effective in 18 of the 23(78%) patients in group C, although improvement of total IPSS and voiding symptom score of IPSS at 12 weeks after treatment was better in group C than in group A or group B, the difference was not significant. In patients with IPSS less than 20, the degree of improvement of IPSS was similar among the 3 groups. In contrast, in patients with IPSS of 20 or greater the degree of improvement was better in group C than in group B or group C, but the difference was not significant. Storage symptom score of IPSS was significantly improved in all 3 groups without any significant difference among the 3 groups. Three patients (52, 59 and 76 years old) experienced abnormal ejaculation. In conclusion, 4 mg of silodosin daily showed effectiveness against BPH/LUTS, but 8 mg of silodosin daily might be better for patients with severe LUTS.

Comparison of emergent versus elective laparoscopic common bile duct exploration for patients with or without nonsevere acute cholangitis complicated with common bile duct stones

Background

Laparoscopic common bile duct exploration (LCBDE) has already been established for the treatment of patients with common bile duct stones (CBDS) in elective situations. However, the effect of emergent LCBDE on those patients with nonsevere acute cholangitis has not been assessed. The aim of this study was to evaluate the effect of emergent LCBDE on patients with nonsevere acute cholangitis complicated with CBDS.

Methods

Seventy-two patients with CBDS admitted from January 2009 to December 2012 were included for this retrospective study. LCBDE of transductal approach for CBDS was performed to all patients. Thirty-seven patients underwent emergent LCBDE for nonsevere acute cholangitis and 35 patients underwent elective LCBDE. Duration of the procedure, complications, retained stone of bile duct, hospital stay, and total charges were compared between the two groups. In addition, the characteristics of patients underwent emergent LCBDE were also compared before and after surgery.

Results

There was no significant difference with regard to the diameter of common bile duct and number of CBDS from imaging and/or operative findings between the two groups. There was no conversion to open common bile duct exploration, no major bile duct injuries, and no mortality in both the group of patients. There was no significant difference in patients with or without acute or chronic cholecystitis, duration of surgery, overall hospital stay (16.41 ± 1.03 versus 14.54 ± 0.94, P > 0.05), and total charges (18,603 ± 1774.64 versus 14,951 ± 1257.09 Yuan in renminbi, P > 0.05) between the two groups. Four cases with retained stones were found in patients with emergent LCBDE and two in elective LCBDE patients. There were four cases of biliary leak in patients with emergent LCBDE and three cases in elective LCBDE group, respectively. However, there was no statistical difference between the two groups. The biliary leak was cured postoperatively after drainage. Control of septic symptoms was achieved in all patients after emergent LCBDE.

Conclusions

Our data indicated that emergent LCBDE is as safe and effective as elective LCBDE for the treatment of patients with nonsevere acute cholangitis complicated with CBDS.
