Bovine pericardial patch: A good alternative in femoral angioplasty.

OBJECTIVE: Bovine pericardial patch (BPP) is currently used in femoral angioplasty as an alternative for autologous vein patch (AVP), but studies comparing the results of the two methods are scarce. In this retrospective study, we aimed to discover the differences between BPP and AVP closure in long-term durability. METHODS: This study consisted of all femoral endarterectomies with BPP closure performed in Helsinki University Hospital from January 1, 2014, to December 31, 2017. For comparison, the same number of consecutive patients who underwent femoral endarterectomy with AVP closure from January 1, 2014, to October 16, 2016, were reviewed. Follow-up ended December 31, 2020. The mean follow-up was 19 months (range, 0-74 months) in the BPP group and 22 months (range, 0-79 months) in the AVP group. The primary endpoint was primary patency. Secondary endpoints were restenosis at patch site detected by imaging or perioperatively, patch rupture, and deep surgical wound infection. Propensity score analysis was performed for adjustment of differences between the AVP and BPP groups. RESULTS: Overall primary patency was superior in the AVP group compared with the BPP group: at 1 year, 96.5% vs 85.0% and at 5 years, 83.0% vs 72.3% (P = .04). In propensity score-matched pairs (n = 92), no difference was found between the groups in primary patency: 95.7% and 95.7% at 1 year and 92.5% and 78.6% at 5 years (P = .861) or in freedom from restenosis: 100% and 100% at 1 year and 89.1% and 84.0% at 5 years (P = .057). Deep wound infections occurred slightly more often after BPP closure (8%) than after AVP closure (4%), but the difference was not statistically significant (P = .144). There were no patch ruptures in the BPP group, but in the AVP group, there were five ruptures (3.5%) (P = .024). CONCLUSIONS: BPP is compatible to AVP in femoral endarterectomy in patency and can be regarded as the safer choice considering the risk of patch rupture.

Open Mesh Repair for Inguinal Hernia is Safer than Laparoscopic Repair or Open Non-mesh Repair: A Nationwide Registry Study of Complications.

BACKGROUND: Inguinal hernia repair is the most common elective procedure in general surgery. Therefore, the number of patients having complications related to inguinal hernia surgery is relatively large. The aim of this study was to compare complication profiles of inguinal open mesh (OM) hernioplasties with open non-mesh (OS) repairs and laparoscopic (LAP) repairs using retrospective nationwide registry data. METHODS: The database of the Finnish Patient Insurance Centre (FPIC) was searched for complications of inguinal and femoral hernia repairs during 2002-2010. Complications of OM repairs were compared to complications of OS repairs and LAP repairs. RESULTS: Over 75 % of all inguinal hernia procedures during the study period in Finland were OM hernioplasties. FPIC received 245 complication reports after OM repairs, 40 after OS repairs, and 50 after LAP repairs. Reported complications were significantly more severe after LAP and OS repairs than OM surgery (p<0.001). Visceral complications (p<0.001), deep infections (p<0.001), and deep hemorrhagic complications (p<0.001) were overrepresented in the LAP group. In the OS group, visceral complications (p<0.001), recurrences (p<0.001), and severe neuropathic pain (p<0.001) predominated. CONCLUSION: LAP and OS repairs of inguinal hernia were associated with more severe complications than open surgery with mesh in this study.

Allelic variants of IL1R1 gene associate with severe hand osteoarthritis.

BACKGROUND: In search for genes predisposing to osteoarthritis (OA), several genome wide scans have provided evidence for linkage on 2q. In this study we targeted a 470 kb region on 2q11.2 presenting the locus with most evidence for linkage to severe OA of distal interphalangeal joints (DIP) in our genome wide scan families. METHODS: We genotyped 32 single nucleotide polymorphisms (SNPs) in this 470 kb region comprising six genes belonging to the interleukin 1 superfamily and monitored for association with individual SNPs and SNP haplotypes among severe familial hand OA cases (material extended from our previous linkage study; n = 134), unrelated end-stage bilateral primary knee OA cases (n = 113), and population based controls (n = 436). RESULTS: Four SNPs in the IL1R1 gene, mapping to a 125 kb LD block, provided evidence for association with hand OA in family-based and case-control analysis, the strongest association being with SNP rs2287047 (p-value = 0.0009). CONCLUSIONS: This study demonstrates an association between severe hand OA and IL1R1 gene. This gene represents a highly relevant biological candidate since it encodes protein that is a known modulator of inflammatory processes associated with joint destruction and resides within a locus providing consistent evidence for linkage to hand OA. As the observed association did not fully explain the linkage obtained in the previous study, it is plausible that also other variants in this genome region predispose to hand OA.

Lichtenstein hernioplasty versus totally extraperitoneal laparoscopic hernioplasty in treatment of recurrent inguinal hernia--a prospective randomized trial.

OBJECTIVE: To compare the Lichtenstein hernioplasty with a totally extraperitoneal preperitoneal laparoscopic technique (TEP) in treatment of recurrent inguinal hernias. SUMMARY BACKGROUND DATA: Only a few studies thus far have compared an open and laparoscopic approach with the treatment of recurrent inguinal hernia in a prospective randomized study setting. METHODS: Ninety-nine patients undergoing surgery for recurrent inguinal hernia were prospectively randomized into having either open or laparoscopic mesh repair. Pre, peri- and postoperative factors were recorded in addition to 3-year follow-up data at the outpatient clinic. At 5-10 years, the patients were interviewed via telephone for recurrent symptoms. The primary end-points chosen were hernia recurrence and chronic pain. RESULTS: Preoperative factors did not differ between the 2 groups. Rerecurrence rates were 3 in the Lichtenstein group and none in the TEP group (6.4% versus 0.0%, respectively), but this difference was statistically not significant. Chronic pain was more prevalent in the Lichtenstein group compared with the TEP group (13 [27.7%] versus 4 [8.2%] patients, respectively, P = 0.02). Postoperatively, the Lichtenstein group needed more pain medication than the TEP group (4.4 versus 3.0 doses, respectively, P = 0.02) and returned to work later (17.9 versus 14.8 days, respectively, P = 0.05). CONCLUSIONS: The laparoscopic technique with mesh in the treatment of recurrent inguinal hernia was proven superior to the open mesh repair in several important clinical aspects, with concomitant improvement in patient satisfaction.

Interleukin 1 polymorphisms and intervertebral disc degeneration.

BACKGROUND: Enzymatic breakdown of the extracellular matrix, and possibly local inflammation, contributes to intervertebral disc degeneration. We investigated whether polymorphisms within the IL-1 gene locus are associated with lumbar disc degeneration and whether the effect of occupational physical load on disc degeneration is modified by the polymorphisms. METHODS: Genotypes were determined from 133 middle-aged men who underwent magnetic resonance imaging of the lumbar spine. The participants represented 3 occupations: 40 were machine drivers, 42 carpenters, and 51 office workers. We evaluated decreased signal intensity of the nucleus pulposus, disc bulges, and decreased disc height as signs of degeneration in the L2/L3-L5/S1 discs. RESULTS: The odds ratio for disc bulges was 2.4 (95% confidence interval = 1.2-4.8) and 1.9 (1.0-3.7), in carriers of the IL-1alphaT or IL-1betaT alleles, respectively. The TT genotype of the IL-1alpha gene carried more than 3-fold risk of disc bulges as compared with the CC genotype. CONCLUSIONS: IL-1 gene cluster polymorphisms could affect the risk of disc degeneration. The effect of physical workload seems to be modified by the IL-1 gene polymorphisms.
