RESUMO
The aim of this study was to develop evidence-based recommendations for determining the surgical extent in patients with locally invasive differentiated thyroid cancer (DTC). Locally invasive DTC with gross extrathyroidal extension invading surrounding anatomical structures may lead to several functional deficits and poor oncological outcomes. At present, the optimal extent of surgery in locally invasive DTC remains a matter of debate, and there are no adequate guidelines. On October 8, 2021, four experts searched the PubMed, Embase, and Cochrane Library databases; the identified papers were reviewed by 39 experts in thyroid and head and neck surgery. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the quality of evidence, and to develop and report recommendations. The strength of a recommendation reflects the confidence of a guideline panel that the desirable effects of an intervention outweigh any undesirable effects, across all patients for whom the recommendation is applicable. After completing the draft guidelines, Delphi questionnaires were completed by members of the Korean Society of Head and Neck Surgery. Twenty-seven evidence-based recommendations were made for several factors, including the preoperative workup; surgical extent of thyroidectomy; surgery for cancer invading the strap muscles, recurrent laryngeal nerve, laryngeal framework, trachea, or esophagus; and surgery for patients with central and lateral cervical lymph node involvement. Evidence-based guidelines were devised to help clinicians make safer and more efficient clinical decisions for the optimal surgical treatment of patients with locally invasive DTC.
RESUMO
Membranous croup is a rare disease that is characterized by diffuse inflammation of the larynx, trachea, and bronchi with adherent or semiadherent mucopurulent membranes in the subglottic trachea and larynx. All cases have occurred in children and there has been no case of adults. The clinical signs, symptoms, progress and prognosis of membranous croup are more severe than those of ordinary croup. The detached membrane in membranous croup may cause a high degree of air way obstruction and give similar characteristics of laryngeal diphtheria, thus it is important to differentiate it from diphtheria by identifying the pathogen. Herein we report with a review of literature a rare case of adult membranous croup caused by methicillin-resistant staphylococcus aureus mimicking laryngeal diphtheria.
RESUMO
Background and Objectives@#Transsphenoidal (TS) surgery for removal of pituitary lesions has become popular with improvements in diagnostic and treatment modalities, as well as endonasal and endoscopic methods, resulting in reduced complications. Rhinosinusitis (RS) is considered a risk factor for postoperative intracranial infections. Previously, we showed that concurrent TS surgery and endoscopic sinus surgery (ESS) yielded a favorable outcome in cases with pituitary lesions and RS. However, there seems to be a lack of consensus in performing simultaneous TS and ESS for patients with a pituitary lesion and RS. We would like to validate the feasibility of performing two operations concurrently.Subjects and Method We reviewed the medical records of 13 patients who underwent simultaneous TS surgery and ESS between 2007 and 2016. One patient underwent concurrent TS surgery and ESS twice due to the regrowth of pituitary macroadenoma and recurrence of RS. @*Results@#There were only four minor nasal complications during the postoperative period, which were controlled with conservative treatment. Only one patient exhibited postoperative cerebrospinal fluid leakage and no patients experienced intracranial complications. @*Conclusion@#This study shows that it might be better to treat patients with pituitary lesion and RS simultaneously. Also, further studies with large cases would be necessary to manage these patients without intracranial complications.
RESUMO
PURPOSE: The efficacy of periarticular multimodal drug injection and adductor canal block after a medial opening-wedge high tibial osteotomy was compared in terms of the postoperative pain level. MATERIALS AND METHODS: From November 2016 to March 2017, 60 patients underwent a medial opening-wedge high tibial osteotomy under spinal anesthesia. Preemptive analgesic medication, intravenous patient controlled anesthesia were used for pain control in all patients. Thirty patients received a periarticular multimodal drug injection (group I), and 30 patients received an adductor canal block (group II). These two groups were compared regarding the postoperative pain level, frequency of additional tramadol injections, total amount of patient-controlled analgesia, and number of times that the patients pushed the patient-controlled analgesia button at each time interval. RESULTS: The visual analogue scale scores over the two-week postoperative period showed no statistical significance. The frequency of additional tramadol hydrochloride injections was similar in the two groups over time. The mean number of times that patients pushed the patient-controlled analgesia button was similar in two groups over time. The total amount of patient-controlled analgesia was similar in the two groups over time. CONCLUSION: This study shows that intraoperative periarticular multimodal drug injections and adductor canal block may have a similar effect on postoperative pain control in patients who have undergone a medial opening-wedge high tibial osteotomy for unicompartmental osteoarthritis of the knee.

PURPOSE: This study evaluated the efficacy of blood mixed cement for osteoporotic vertebral compression fractures in reducing the complications of percutaneous vertebroplasty using conventional cement. MATERIALS AND METHODS: This study was performed retrospectively in 80 patients, from January 2016 to January 2017. Porous cement was formed by mixing 2, 4, and 6 ml of blood with 20 g of cement used previously. A tube with a diameter and length of 2.8 mm and 215 mm, respectively, was used and the polymerization temperature, setting time, and optimal passing-time were measured and compared with those using only conventional cement. Radiologically, the results were evaluated and compared. RESULTS: The polymerization temperature was 70.3℃, 55.3℃, 52.7℃, and 45.5℃ in the conventional cement (R), 2 ml (B2), 4 ml (B4), and 6 ml (B6), respectively, and the corresponding setting time decreased from 960 seconds (R) to 558 seconds (B2), 533 seconds (B4), and 500 seconds (B6). The optimal passing-time was 45 seconds (B2), 60 seconds (B4), and 78 seconds (B6) at 73 seconds (R), respectively and as the amount of blood increased, it was similar to the cement passing-time. The radiological results showed that the height restoration rates and the vertebral subsidence rates similar among the groups. Two cases of adjacent vertebral compression fractures in the R group and one in the B2 and B4 groups were encountered, and the leakage rate of the cement was approximately two times higher than that in the conventional cement group. CONCLUSION: In conventional percutaneous vertebroplasty, the procedure of using autologous blood with cement decreased the polymerization temperature, reduced the setting time, and the incidence of cement leakage was low. These properties may contribute to more favorable mechanical properties that can reduce the complications compared to conventional cements alone.

PURPOSE: We compared adductor canal block (ACB) alone and a combination of ACB and sciatic nerve block (SNB) to control early postoperative pain after total knee arthroplasty. MATERIALS AND METHODS: One hundred patients received continuous ACB alone (group A), and another 100 patients received continuous ACB and single popliteal SNB (group B). Pain was evaluated at rest and 45° knee flexion using the numeric rating scale (NRS). The number of times the patient pressed the intravenous patient-controlled analgesia (PCA) button, total PCA volume infused, and the total dosage of additional analgesics were evaluated. We also investigated complications associated with each pain control technique. RESULTS: The NRS score on postoperative day 1 was significantly lower in group B than in group A. The number of times patients pressed the PCA button on postoperative day 1 and the total infused volume were significantly lower in group B than in group A. Thirty-five (35%) patients in group B developed foot drop immediately after surgery; but they all fully recovered on postoperative day 1. CONCLUSIONS: SNB can be effective for management of early postoperative pain that persists even after ACB. Further research is needed to determine the proper dosage and technique for reducing the incidence of foot drop.

BACKGROUND: Palmar hyperhidrosis is a common disorder of excessive sweating. A number of studies have demonstrated the effectiveness of iontophoresis in the treatment of palmar hyperhidrosis. However, controlled clinical studies on iontophoresis for palmar hyperhidrosis have been limited. OBJECTIVE: To determine the efficacy and safety of iontophoresis in the treatment of palmar hyperhidrosis with a randomized, sham-controlled, single-blind, and parallel-designed study. METHODS: Twenty nine patients with significant palmar hyperhidrosis were enrolled in this study. They received active iontophoresis treatment (group A) or sham treatment (group B). Iontophoresis was performed 20 minutes each time, five times per week, for 2 weeks. Its efficacy was assessed with starch-iodine test, mean sweat secretion rate, and hyperhidrosis disease severity scale. RESULTS: Twenty-seven of the 29 patients completed the 2-week treatment. After completion of 10 times of treatment, results of the starch-iodine test showed clinical improvement in 92.9% of patients in group A and 38.5% of patients in group B (p=0.001). The mean sweat secretion rate was reduced by 91.8% of patients in group A and by 39.1% of patients in group B (p<0.001). Improvement in quality of life was reported by 78.6% of patients in group A and by 30.8% of patients in group B (p=0.028). In group A, one case of localized adverse event was noted, although no adverse event was encountered in group B. CONCLUSION: Tap water iontophoresis could be used as an effective and safe treatment modality for palmar hyperhidrosis.

PURPOSE: The purpose of this study was to analyze patient factors including smoking, body mass index, correction angle, graft material, presence of lateral cortex fracture, and age for the effect on bone union after open-wedge high tibial osteotomy and the effect of graft material used for lateral cortex fractures. MATERIALS AND METHODS: This retrospective study was conducted on 54 patients and 58 cases with osteoarthritic change Kallgren-Lawrence grade 2 or less from May 2012 to June 2014. Average follow-up period was 22 months (14–38 months). The patients were divided into two groups according to patient related factors and graft materials (allograft, n=6; beta-tricalcium phosphate [β-TCP], n=6) used for lateral cortex fractures and were analyzed for the relationship with bone union after open-wedge high tibial osteotomy. Radiographic and clinic analyses were performed, and van Hemert grading was used for grading bone union at 6 weeks, 3 months, 6 months, and 1 year postoperatively. RESULTS: The non-smoking group and the group without lateral cortex fracture showed significantly higher bone union rates than the control group. No significant clinical or radiological difference was observed between the two groups in 12 cases and the allograft group showed significantly higher rates of union at 6 months and 1 year postoperatively according to the van Hemert grading. CONCLUSION: Smoking and the presence of a lateral cortex fracture is a risk factor for nonunion in medial open-wedge high tibial osteotomy. The use of allograft material rather than β-TCP for lateral cortex fractures is thought to result in better bone union.

PURPOSE: The purpose of this study was to evaluate the clinical results of fixation of the unstable osteochondral dissecans (OCD) lesion with autologous osteochondral plugs. MATERIALS AND METHODS: This study was conducted in 19 patients who were relevant to the International Cartilage Repair Society 2, 3, or 4 who were treated with autologous osteochondral plugs and followed-up for more than 2 years from January 2004 to January 2012. Clinical evaluation was performed by comparing the preoperative and last follow-up scores of Lysholm score and subjective International Knee Documentation Committee (IKDC) score. RESULTS: All patients were male and the average age was 19.1 years. Of the 19 cases, there were 16 cases of medial femoral condyle lateral side lesion, 2 cases of lateral femoral condyle articular surface, and 1 case of femoral intercondylar notch lesions. The average size of the lesion was 5.68 mm2, and average use of osteochodral plugs were 4.3. Average follow-up period was 38 months. Preoperative Lysholm score, IKDC subjective score showed significant improvement. CONCLUSION: Fixation with autologous osteochondral plugs for unstable OCD uses the remnant tissues therefore conserving it, which is thought to be the positive aspect of this type of operation.

We recently experienced a case of transoral endoscopic thyroidectomy via the trivestibular approach. We identified and preserved all neighboring critical structures during surgery. The patient was discharged on postoperative day 3. There were no complications in thyroid function, vocal cord function, or lower lip sense. Transoral endoscopic thyroidectomy via a trivestibular approach provides a short and direct route to the thyroid and an adequate workspace without a skin incision. Therefore, it is worthwhile to develop and refine the surgical techniques of this promising new surgical approach.

BACKGROUND: Thyroid autoimmunity has been increasingly reported to be associated with chronic urticaria (CU), and the possible clinical benefit of thyroid hormone or anti-thyroid drugs in some CU patients with autoimmune thyroid disease has been studied. However, the effect of thyroid hormone or anti-thyroid drugs on clinical symptoms of CU remains unclear. OBJECTIVE: We investigated the clinical response of urticaria to the treatment of thyroid dysfunction. METHODS: Medical records of patients with CU evaluated for thyroid autoimmunity and thyroid function were collected and reviewed. RESULTS: Of 184 patients with CU, 43 patients (23.4%) had thyroid autoantibodies and 26 patients (14.1%) had thyroid dysfunction. While none of the five patients with Graves' disease showed any improvement of urticaria after treatment with anti-thyroid drugs, two of the 10 patients with Hashimoto's thyroiditis showed improved urticaria after being treated with levothyroxine. CONCLUSION: Although levothyroxine treatment was effective in a minority of patients with CU, there may be a causal relationship between CU and thyroid autoimmunity.

Popliteal artery compression rarely occurs after posterior cruciate ligament (PCL) reconstruction using the tibial inlay technique that allows for direct visualization of the surgical field. However, we experienced a popliteal artery compression after PCL reconstruction performed using the technique, which eventually required re-operation. Here, we report this rare case and discuss reasons of popliteal artery compression.

Autoimmune progesterone dermatitis is a rare disorder involving hypersensitivity to progesterone. It is most frequently characterized by recurrent erythema multiforme, eczematous or urticarial eruptions during the luteal phase of the menstrual cycle. It resolves or partially improves after menstruation. Sensitivity is demonstrated by a challenge test with medroxyprogesterone acetate. The therapeutic goal for autoimmune progesterone dermatitis is the suppression of ovulation. Currently, the first-line choice of therapy is a combination oral contraceptive. Here, we report a case of autoimmune progesterone dermatitis that manifested as cyclic bullous erythema multiforme. A reactive intradermal progesterone test confirmed the diagnosis.

Nuchal-type fibroma is a rare, benign, fibrous, tumor-like proliferation characterized by dense hypocellular bundles of collagen, with sparsely scattered fibroblasts, interspersed fat tissue, and entrapped nerve fibers. It usually develops in the posterior neck as a solitary, firm, poorly circumscribed, subcutaneous mass. Herein, we report about a 32-year-old man who presented with a 6-year history of multiple nodules on the scalp. Histopathological features were consistent with those of nuchal-type fibroma. The tumors were surgically excised.

BACKGROUND: Dermatofibroma (DF) comprises a heterogeneous group of mesenchymal tumors, with fibroblastic and histiocytic elements present in varying proportions. The cell of origin of DF has been investigated, but remains unclear. OBJECTIVE: The present study attempted to investigate the expression of leukocyte-specific protein 1 (LSP1), a marker of fibrocytes, in DF. Additionally, we evaluated the effectiveness of LSP1 in the differential diagnosis of DF from dermatofibrosarcoma protuberans (DFSP). METHODS: Immunohistochemical staining was performed on 20 cases of DF using antibodies against LSP1, CD68, and factor XIIIa (FXIIIa). In addition, the expression of LSP1 and FXIIIa was evaluated in 20 cases of DFSP. RESULTS: Eighteen of 20 cases (90%) of DF stained positive for LSP1, with variation in the intensity of expression. CD68 was positive in 10 cases (50%), and FXIIIa was expressed in all cases of DF. There were differences between the regional expression patterns of the three markers in individual tumors. In contrast, only 2 of 20 cases of DFSP expressed LSP1, and none of DFSP cases stained positive for FXIIIa. CONCLUSION: The LSP1-positive cells in DF could potentially be fibrocyte-like cells. FXIIIa and CD68 expression suggests that dermal dendritic cells and histiocytes are constituent cells of DF. It is known that fibrocytes, dermal dendritic cells and histiocytes are all derived from CD14+ monocytes. Therefore, we suggest that DF may originate from CD14+ monocytes. Additionally, the LSP1 immunohistochemical stain could be useful in distinguishing between DF and DFSP.

Hairy polyps are rare congenital benign masses of the head and neck. They mainly occur in the nasopharynx and oropharynx. This paper reports a 12-month-old female patient who had a 0.5-cm sausage-shaped mass in the left nasal vestibule with nasal obstruction and habitual nose-picking. This lesion was surgically removed with no complications under monitored anesthesia. There was no evidence of recurrence through 24 months. To the best our knowledge, this is the first English literature report of a patient with a hairy polyp arising from a nasal vestibule.

BACKGROUND: The purpose of the present study is to investigate the anesthetic effect of reduced doses of spinal bupivacaine with epidural top ups in comparison with those of spinal bupivacaine and to determine the adequate doses of drugs used during lower extremity surgeries. METHODS: Sixty adult patients were randomized to three different technique groups: S group (10 mg of spinal bupivacaine), SE1 group (7.5 mg of spinal bupivacaine + epidural 1.5% lidocaine 10 ml) or SE2 group (5 mg of spinal bupivacaine + epidural 1.5% lidocaine 10 ml). The level of sensory block, modified Bromage motor scores (MBS), systolic blood pressure and heart rate were recorded for 30 min following anesthesia. Peak sensory block height and MBS, time for sensory regression to L1 and motor recovery to MBS 1, side effects and operator's satisfaction were noted. RESULTS: The levels of peak sensory block were similar among the groups (P > 0.05). For the SE2 group, the regression to the L1 dermatome was faster (P = 0.004) and the maximum MBS was lower (P = 0.001) than that of the other two groups. Motor block recovery to MBS 1 was faster for the SE1 and SE2 groups than for the S group (P < 0.001). The operator's satisfaction scores of the SE2 group were lower than those of the other two groups (P = 0.019). CONCLUSIONS: During combined spinal-epidural anesthesia, 7.5 mg of spinal bupivacaine and epidural 1.5% lidocaine 10 ml produced faster motor recovery than did 10 mg of spinal bupivacaine in patients undergoing lower extremity surgeries.
