Case for staged thyroidectomy

Recent modifications in the management of well‐differentiated thyroid cancer have resulted in significant alterations in clinical approach. Utilizing a series of preoperative and postoperative risk factors involving both the patient and the disease pathology, we offer the term “staged thyroidectomy” to help organize these risk factors for patients and the endocrine team to optimize management. This approach is intended to incorporate our latest nuanced understanding of certain endocrine pathology and may serve to optimize patient outcomes.     

Repeated metal ion measurements in patients with high risk metal-on-metal hip replacement

Purpose

Conventional follow-up methods are not sufficient to identify adverse soft tissue reactions in patients with metal-on-metal hip replacements. The national guidelines regarding metal ion measurements are debatable. The aims of our study were to investigate (1) if there is a clinically significant change in whole blood (WB) cobalt (Co) or chrome (Cr) levels in repeated WB assessment in patients operated on with ASR hip replacements, and (2) what proportion of patients has WB Co or Cr level below the previously established safe upper limits (SUL) in the repeated WB metal ion assessment.

Methods

We identified all patients (n = 254) with unilateral ASR implants who had second blood sample taken eight to 16 months after the first.

Results

WB Co and Cr levels remained below SUL and within their initial values during a mean one-year measurement interval in the majority of patients with a high risk HR device. In contrast to this, 50 % of patients with THRs had metal ion levels exceeding the SUL in the first measurement. WB Co values significantly increased over the measurement interval in the THR group.

Conclusion

In patients with a high risk HR, repeated metal ion measurement did not provide useful information for clinical decision-making. In patients with a LD MoM THR repeated measurements revealed a large number of patients with metal ion levels exceeding SUL and might thus be clinically beneficial.     

Continuous Absorbable Intradermal Sutures Yield Better Cosmetic Results than Nonabsorbable Interrupted Sutures in Open Appendectomy Wounds: A Prospective,Randomized Trial

Background

Acute appendicitis is the most common reason for abdominal surgery in young adults and children. Open appendectomy is still the treatment often chosen because it is simple, safe, and effective. Our aim was to study whether cosmetic results of appendectomy wounds are better after using continuous absorbable intradermal (A) sutures compared with wound closure with interrupted nonabsorbable (NA) sutures.

Methods

A total of 206 adult patients with clinically suspected appendicitis were allocated to the study and prospectively randomized into two wound-closure groups: the interrupted NA suture group and the A suture group. Of these, 193 patients with sufficient data were invited to the outpatient clinic for cosmetic analysis. Cosmetic results were evaluated after a median of 14 months. For subjective scar assessment, the Vancouver scar scale, the patient and observer scar assessment scale (POSAS), and a visual analog scale (VAS) were used. Objective evaluation was carried out by measuring surface area, average width, and estimated concentration change (ECC) of hemoglobin and melanin in the scar using spectrocutometry. For statistical analyses we used the Mann–Whitney test and Student’s t test.

Results

Both objective and subjective analyses showed better cosmetic results for absorbable intradermal suturing. The difference between the two groups was statistically significant as regards POSAS in both patient (p = 0.032) and observer scales (p = 0.001), and VAS (p = 0.002). Scar surface area was significantly smaller in group A than in group NA (p = 0.002). ECC measurements showed higher values for melanin in group NA than in group A (p = 0.034).

Conclusion

Continuous intradermal absorbable suturing yields a better cosmetic result than interrupted nonabsorbable suturing in lower abdominal transverse appendectomy.     

Total Knee Arthroplasty with an Uncemented Trabecular Metal Tibial Component : A Registry-Based Analysis

Previous poor results have kept the appeal of uncemented total knee arthroplasties (TKAs) minimal. We analyzed the mid-term survivorship and reasons for failures of a contemporary uncemented porous tantalum monoblock tibial component nation-wide. During the study period (2003–2010), such tibial components were used in 1143 primary TKAs recorded in the Finnish Arthroplasty Registry. Seven-year survivorship of these TKAs was 100% (95% CI 99–100) with revision for aseptic loosening of the tibial component, and 97% (95% CI 96–98) with revision for any reason as the respective end points. The most common reasons for revisions were instability and prosthetic joint infections. In conclusion, TKAs using an uncemented porous tantalum monoblock tibial component showed excellent mid-term survivorship in a population-based setting.     

Long‐term outcome of intraventricular conduction delays in the general population

BackgroundPrevious population studies have presented conflicting results regarding the prognostic impact of intraventricular conduction delays (IVCD).MethodsWe studied long‐term prognostic impact and the association with comorbidities of eight IVCDs in a random sample of 6,299 Finnish subjects (2,857 men and 3,442 women, mean age 52.8, SD 14.9 years) aged 30 or over who participated in the health examination including 12‐lead ECG. For left bundle branch block (LBBB) and non‐specific IVCD (NSIVCD), two different definitions were used.ResultsDuring 16.5 years’ follow‐up, 1,309 of the 6,299 subjects (20.8%) died and of these 655 (10.4%) were cardiovascular (CV) deaths. After controlling for known clinical risk factors, the hazard ratio for CV death, compared with individuals without IVCD, was 1.55 for the Minnesota definition of LBBB (95% confidence interval 1.04–2.31, p = .032) and 1.27 (95% confidence interval 0.80–2.02, p = .308) for the Strauss’ definition of LBBB. Subjects with NSIVCD were associated with twofold to threefold increase in CV mortality depending on the definition. While right bundle branch block, left anterior fascicular block and incomplete bundle branch blocks were associated with seemingly higher mortality, this was no longer the case after adjustment for age and sex. The presence of R‐R’ pattern was not associated with any adverse outcome.ConclusionsIn a population study with long‐term follow‐up, NSIVCD and Minnesota definition of LBBB were independently associated with CV mortality. Other IVCDs had no significant impact on prognosis. The prognostic impact of LBBB and NSIVCD was affected by the definition of the conduction disorder.
