Increasing evidence indicates that inflammation plays a crucial role in cancer development. A novel scoring system based on albumin and the neutrophil-to-lymphocyte ratio (NLR) was developed and incorporated into a nomogram to create a more accurate prognostic tool for oral cavity squamous cell carcinoma (OSCC) patients. A retrospective review was performed on 613 consecutive patients undergoing ablative surgery for OSCC between September 2005 and December 2014. NLR and albumin were determined and used to calculate an albumin/NLR score (ANS). The nomogram was based on the ANS and several clinicopathological manifestations, and its accuracy was determined by the concordance index (c-index). A high ANS was significantly associated with aggressive tumor behaviors, such as T status, overall stage, extranodal extension, perineural invasion, tumor depth, and decreased overall survival (OS). Multivariate analysis indicated that age, overall stage, extranodal extension, and ANS were independent factors for OS. The c-index for OS prognosis was 0.750 using this nomogram compared to 0.688 using TNM staging alone. The prognostic accuracy for OS in OSCC patients can be significantly improved using a nomogram that incorporates the novel ANS and other clinicopathological variables.

Background:Primary lymphedema is a debilitating disease. This study was to investigate the outcomes between vascularized lymph node transfer (VLNT) and lymphovenous anastomosis (LVA) for treating primary lymphedema.Methods:Between January 2010 and December 2016, 17 patients with mean age of 31.5 ± 15.5 (ranged, 2–57) years diagnosed with 19 primary limb lymphedema were recruited. Patients with patent lymphatic ducts on indocyanine green lymphography were indicated for LVA, whereas those without patent lymphatic ducts were indicated for VLNT. Circumferential limb measurements, body weight, episodes of cellulitis and Lymphedema Quality-of-Life (LYMQoL) questionnaire were compared between preoperatively and postoperatively.Results:Fifteen lymphedematous limbs underwent VLNT (79%) and 4 underwent LVA (21%). All VLNT flaps survived. At a mean follow-up of 19.7 ± 8.5 months, mean reduction of limb circumference, body weight, and episodes of cellulitis were 3.7 ± 2.9 cm and 1.9 ± 2.9 cm (P = 0.2); 6.6 ± 5.9 kg and 1.7 ± 0.6 kg (P < 0.05); 5.1 ± 2.8 times/y and 4.2 ± 0.5 times/y in VLNT and LVA groups, respectively (P = 0.7). Improvements in overall score (from 3.9 ± 1.2 to 6.4 ± 1.1, P < 0.05) of the LYMQoL in VLNT group had statistical significant difference than that (from 3.0 ± 1.4 to 5.0 ± 2.4, P = 0.07) in LVA group.Conclusions:Both VLNT and LVA can effectively treat primary lymphedema patients. The reduction of above-knee circumference, body weight, episodes of cellulitis, and the improvement of LYMQoL was significantly greater in LVNT compared with LVA.

Patients compliance has a significant impact on treatment efficacy with intranasal steroids. There is a discrepancy between reported and actual compliance. It is thus important to establish the actual compliance when evaluating patients who fail to respond to therapy.

The minimal invasive techniques have become the main stay of the surgical approach for the cochlear implant. Securing the implant with sutures can be challenging due to the limited access and awkward operating angle. We have developed a non-sutured technique to secure the implant by placing and securing the proximal end of the electrode into a bony groove. Our series supports the notion that the technique is suitable for implant cases in which the patient's age is older than 18 months.

Lupus is characterized by a loss of B cell tolerance leading to autoantibody production. In this study, we explored the mechanisms underlying this loss of tolerance using B6 congenic mice with an interval from New Zealand Black chromosome 1 (denoted c1(96–100)) sufficient for anti-nuclear antibody production. Transgenes for soluble hen egg white lysozyme (sHEL) and anti-HEL immunoglobulin were crossed onto this background and various tolerance mechanisms examined. We found that c1(96–100) mice produced increased levels of IgM and IgG anti-HEL antibodies compared to B6 mice and had higher proportions of germinal center B cells and long-lived plasma cells, suggesting a germinal center-dependent breach of B cell anergy. Consistent with impaired anergy induction, c1(96–100) double transgenic B cells showed enhanced survival and CD86 upregulation. Hematopoietic chimeric sHEL mice with a mixture of B6 and c1(96–100) HEL transgenic B cells recapitulated these results, suggesting the presence of a B cell autonomous defect. Surprisingly, however, there was equivalent recruitment of B6 and c1(96–100) B cells into germinal centers and differentiation to splenic plasmablasts in these mice. In contrast, there were increased proportions of c1(96–100) T follicular helper cells and long-lived plasma cells as compared to their B6 counterparts, suggesting that both B and T cell defects are required to breach germinal center tolerance in this model. This possibility was further supported by experiments showing an enhanced breach of anergy in double transgenic mice with a longer chromosome 1 interval with additional T cell defects.

The superficial temporal artery (STA) flap is a versatile flap for head and neck defect reconstruction. It can be based on the frontal branch of the STA and an islanded 360-degree rotation arc for various defects on the scalp, cheek, and auricular region. It provides a nonmicrosurgical option for reconstructing such defects, which is itself relatively easy to perform. However, venous congestion is a problem than often can cause worry to the clinician and hence preclude its use. In this review, we revisit this flap in head and neck reconstruction, with case examples used for reconstruction of defects on the scalp, maxilla, lip, ear, and retroauricular area. The STA flap in our review can be used either as a fasciocutaneous flap or with its fascia alone. The main issue with the STA flap is that it is generally a high-inflow flap with variable outflow. Venous congestion is frequently encountered in our practice, and adequate management of the venous drainage in the postoperative period is crucial in ensuring its success as a versatile and viable option for head and neck reconstruction.
