Objectives  To investigate the expression levels and distribution patterns of elafin and cystatin C in normal and inflammatory human sinus mucosa and to evaluate their roles in chronic sinusitis.

Design  A controlled, prospective study.

Setting  A tertiary academic institution.

Patients  Normal sinus mucosa was obtained from the ethmoid sinus during surgery in 30 patients with blowout fractures. Inflammatory sinus mucosa was obtained from 30 patients undergoing endoscopic sinus surgery for chronic polypoid sinusitis.

Interventions  Reverse transcription–polymerase chain reaction, immunohistochemical analysis, and Western blotting.

Main Outcome Measures  Expression levels and distribution patterns of elafin and cystatin C in normal and inflammatory mucosa.

Results  Expression of elafin and cystatin C messenger RNAs and proteins analyzed by means of reverse transcription–polymerase chain reaction and Western blot was detected in all normal and inflammatory sinus mucosa tested. Their expression levels were increased in inflammatory vs normal mucosa. Elafin in normal and inflammatory sinus mucosa was distinctly expressed in goblet cells, which are increased in inflammatory sinus mucosa. Elafin in submucosal glands was usually weak in staining intensity, except for a few scattered submucosal glands showing moderate intensity in inflammatory sinus mucosa. Cystatin C was also localized in goblet cells and submucosal glands in normal and inflammatory mucosa. Staining intensity was increased more in inflammatory vs normal sinus mucosa.

Conclusion  Elafin and cystatin C may play an important role in the protection of normal sinus mucosa and further in regulation of the inflammatory condition in chronic sinusitis.

The requirements for access control have been increased significantly in smart home systems. Many factors such as user ID, user location, service usage conditions and so on, regarded as authorization attributes, are important in making authorization decision in smart home systems. We investigate into the dynamic characteristics of the authorization in smart home systems and propose a new access-control model, SH-CRBAC, which aims to combine the advantages of attribute-based authorization mechanism and role-based access-control mechanism, and imposes attribute and status constraints on the RBAC model and enhances the generality and flexibility of authorization significantly in smart home systems. The status consistency of SH-CRBAC is analysed, and we also analyse the characteristics of SH-CRBAC through comparison with other popular existing authorization models in smart home systems.

We present the first Korean individual genome sequence (SJK) and analysis results. The diploid genome of a Korean male was sequenced to 28.95-fold redundancy using the Illumina paired-end sequencing method. SJK covered 99.9% of the NCBI human reference genome. We identified 420,083 novel single nucleotide polymorphisms (SNPs) that are not in the dbSNP database. Despite a close similarity, significant differences were observed between the Chinese genome (YH), the only other Asian genome available, and SJK: (1) 39.87% (1,371,239 out of 3,439,107) SNPs were SJK-specific (49.51% against Venter's, 46.94% against Watson's, and 44.17% against the Yoruba genomes); (2) 99.5% (22,495 out of 22,605) of short indels (< 4 bp) discovered on the same loci had the same size and type as YH; and (3) 11.3% (331 out of 2920) deletion structural variants were SJK-specific. Even after attempting to map unmapped reads of SJK to unanchored NCBI scaffolds, HGSV, and available personal genomes, there were still 5.77% SJK reads that could not be mapped. All these findings indicate that the overall genetic differences among individuals from closely related ethnic groups may be significant. Hence, constructing reference genomes for minor socio-ethnic groups will be useful for massive individual genome sequencing.

  Objective

To investigate the long-term outcomes of selected patients with cT3 distal rectal cancer treated with local excision following pre-operative chemoradiotherapy.

Methods

Between January 2003 and February 2008, 11 patients with cT3 distal rectal cancer received a local excision following pre-operative chemoradiotherapy. The median age of the patients was 61 years (range, 42–71). The median tumor size was 3 cm (range, 2–5), and the median distance of the caudal tumor edge from the anal verge was 3 cm (range, 1–4). Clinical lymph node status was positive in five patients. Pre-operative chemoradiotherapy consisted of a 50.4 Gy in 28 fractions with concurrent chemotherapy. A transanal full-thickness local excision was performed after a median of 54 days (range, 31–90) from chemoradiotherapy completion. Ten patients received post-operative chemotherapy.

Results

Pathologically complete responses occurred in eight patients, ypT1 in two and ypT2 in one. The pathologic tumor size for three ypT1–2 tumors was 0.9, 1.1 and 2.2 cm. The follow-up period was a median of 59 months (range, 24–85). One patient (ypT0) developed recurrence at the excision site 14 months after surgery, but was successfully salvaged with an abdominoperineal resection and adjuvant chemotherapy. Another patient (ypT2) developed bone metastasis after 8 months and died of the disease. The 5-year local recurrence-free, disease-free and overall survival rates were 90.9%, 81.8% and 88.9%, respectively. No Grade 3 or worse gastrointestinal toxicity was detected.

Conclusions

Full-thickness local excision following chemoradiotherapy may be an acceptable option for cT3 distal rectal cancer that responds well to chemoradiotherapy.

  Background

There are no reports comparing meniscal healing between inside-out and all-inside repairs using sutures.

Hypothesis

No difference in healing rate exists between meniscal repairs with inside-out and all-inside suture repair in conjunction with anterior cruciate ligament reconstruction with hamstring tendon.

Study Design

Cohort study; Level of evidence, 2.

Methods

Forty-eight consecutive patients underwent meniscal repairs of longitudinal tears of the posterior horn of the medial meniscus combined with anterior cruciate ligament reconstructions. All-inside repair was attempted when the tears were located in the red-red zone or the ramp area of the meniscus. If a tear that was in the ramp area or red-red zone extended to the midbody of the meniscus, or if there was a tear in red-white zone, the inside-out repair technique was used. Fourteen patients had all-inside meniscal repairs, and 34 patients had inside-out meniscal repairs with absorbable sutures. Identical postoperative rehabilitation protocols were used. Postoperative evaluations included Lysholm knee scoring scale, Tegner activity levels, Lachman and pivot-shift tests, and KT-1000 arthrometer. Assessment of meniscal status was performed using joint line tenderness, McMurray test, and range of motion. Follow-up magnetic resonance imaging scans were obtained on all patients.

Results

Mean follow-up was 35.7 months. No patient had joint line tenderness or reported pain or clicking on McMurray test. There was no significant difference in range of motion between groups. Follow-up magnetic resonance imaging scans demonstrated that 10 (71.4%) menisci were healed and 4 (28.6%) partially healed in the all-inside group; 24 (70.6%) menisci were healed and 10 (29.4%) partially healed in the inside-out group. There was no significant difference in meniscal healing between groups. There were no differences in Lachman test, KT-1000 arthrometer side-to-side differences measurements, Lysholm scores, and Tegner activity scales. There was a significant difference in pivot-shift test between groups (P = .023). There were 2 complications associated with surgery. In the inside-out group, 1 patient required manipulation, and 2 patients had limited motion at final follow-up. Two patients in the inside-out group experienced transient saphenous nerve injury.

Conclusion

There was no significant difference in meniscal healing between inside-out and all-inside repair techniques in combination with anterior cruciate ligament reconstructions.

Background: Radial meniscal tears historically have been treated by partial meniscectomy, although they are more biomechanically detrimental than longitudinal tears. Clinical results after meniscal repair for radial tears of the midbody of the lateral meniscus have been reported rarely.

Study Design: Case series: Level of evidence, 4.

Methods: Fourteen consecutive patients who had radial tears of the midbody of the lateral meniscus underwent arthroscopic repair. Inclusion criteria were radial tears involving the red-red or red-white zone. All patients underwent all-inside meniscal repair using absorbable sutures. Postoperative evaluation was performed using joint-line tenderness, McMurray test, range of motion, and follow-up magnetic resonance imaging (MRI) scan at 6 months postoperatively. Lysholm knee score and Tegner activity level were evaluated at last follow-up. In 4 patients, second-look arthroscopies were performed.

Results: The average follow-up was 36.3 months. No patient had joint-line tenderness. Three patients complained of pain or a click on McMurray test. The mean follow-up range of motion was 138.6°. Follow-up MRI scans demonstrated that 5 (35.7%) menisci were healed, 8 (57.1%) were partially healed, and 1 (7.1%) was not healed. The follow-up Lysholm score was 94.7 (range, 81-100; standard deviation [SD] = 6.4) and Tegner score was 5.7 (range, 3-7; SD = 1.4). Second-look arthroscopies in 4 patients showed partial healing of meniscal tears.

Conclusion: Meniscal repair for radial tears of the midbody of the lateral meniscus may be an effective, alternative treatment to partial meniscectomy.
