A rare case is described of an intrathyroidal branchial cleft-like cyst in neonate. The patient was a newborn girl with a mass in the left lateral neck. The ultrasonography and computed tomography revealed a cystic lesion in the left thyroid. The lesion was enucleated surgically from the thyroid. Histologically, the cyst was lined by squamous or columnar epithelium and contained inflammatory cell infiltraion, thyroid and parathyroid tissue. The patient has been doing well without any evidence of thyroid dysfunction for 15 months.

We report two cases of high-risked patients with cardiac dysfunction undergoing femoro-popliteal or tibial arterial bypass surgery anesthetized by ultrasound guided peripheral nerve blocks; femoral nerve, femoral branch of genitofemoral nerve and sciatic nerve block. We used an anesthetic solution consisting of 0.375% ropivacaine with epinephrine. We provided sufficient surgical anesthesia. These nerve blockades provided stable intraoperative and postoperative hemodynamic status, which is valuable knowledge from the perspective of postoperative pain control as well as satisfaction of both patients and surgeons. We believe that femorosciatic nerve block with concurrent femoral branch block of genitofemoral nerve could be an excellent anesthetic choice for patients receiving femoro-popliteal or tibial arterial bypass surgery, especially in patients with cardiac dysfunction.

BACKGROUND: To investigate the effect of high frequency repetitive transcranial magnetic stimulation (rTMS) on motor symptoms especially freezing of gait (FoG), and nonmotor symptoms in Parkinson disease (PD). METHODS: In this randomized, double-blind, sham-controlled study, fifteen PD patients were enrolled. For 10 days, 5 Hz, both motor cortices and dorsolateral prefrontal cortex (DLPFC) were stimulated. The motor symptoms and FoG were evaluated by the Unified Parkinson's Disease Rating Scale (UPDRS) part III, FoG questionnaire (FoG-Q), variable parameters of FoG, and kinematic gait analysis. Nonmotor symptoms were evaluated by the Korean version of non-Motor Symptoms Scale (K-NMSS), 39-item Parkinson disease questionnaire (K-PDQ39), Mini-Mental Status examination (K-MMSE), Montreal Cognitive Assessment (K-MoCA), and Frontal assessment battery (FAB). RESULTS: Finally, 12 patients (real:8, sham:4) data were analyzed. FoG-Q and UPDRS part III were improved (p=0.002, 0.022) and variable parameters of FoG was improved after 10 days stimulation in real treatment group. In addition, their effects maintained until 6 weeks from the baseline. In nonmotor symptoms, K-NMSS and K-PDQ 39 were improved until 6 weeks in real treatment group (p=0.002, 0.002), however no changes were shown in cognitive function test. CONCLUSIONS: The high frequency rTMS was effective for FoG, in addition to motor and a few nonmotor symptoms in PD.

Background: Hemidiaphragmatic paralysis, a frequent complication of the brachial plexus block performed above the clavicle, is rarely associated with an infraclavicular approach. The costoclavicular brachial plexus block is emerging as a promising infraclavicular approach. However, it may increase the risk of hemidiaphragmatic paralysis because the proximity to the phrenic nerve is greater than in the classical infraclavicular approach. Methods: This retrospective analysis compared the incidence of hemidiaphragmatic paralysis in patients undergoing costoclavicular and supraclavicular brachial plexus blocks. Of 315 patients who underwent brachial plexus block performed by a single anesthesiologist, 118 underwent costoclavicular, and 197 underwent supraclavicular brachial plexus block. Propensity score matching selected 118 pairs of patients. The primary outcome was the incidence of hemidiaphragmatic paralysis, defined as a postoperative elevation of the hemidiaphragm > 20 mm. Factors affecting the incidence of hemidiaphragmatic paralysis were also evaluated. Results: Hemidiaphragmatic paralysis was observed in three patients (2.5%) who underwent costoclavicular and 47 (39.8%) who underwent supraclavicular brachial plexus blocks (P < 0.001; odds ratio, 0.04; 95% confidence interval, 0.01-0.13). Both the brachial plexus block approach and the injected volume of local anesthetic were significantly associated with hemidiaphragmatic paralysis. Conclusions The incidence of hemidiaphragmatic paralysis is significantly lower with costoclavicular than with supraclavicular brachial plexus block.

Background: To evaluate the association between inflammation and nutrition-based biomarkers and postoperative outcomes after non-cardiac surgery. Methods: Between January 2011 and June 2019, a total of 102,052 patients undergoing non-cardiac surgery were evaluated, with C-reactive protein (CRP), albumin, and complete blood count (CBC) measured within six months before surgery. We assessed their CRP-to-albumin ratio (CAR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and modified Glasgow Prognostic Score (mGPS). We determined the best cut-off values by using the receiver operating characteristic (ROC) curves. Patients were divided into high and low groups according to the estimated threshold, and we compared the one-year mortality. Results: The one-year mortality of the entire sample was 4.2%. ROC analysis revealed areas under the curve of 0.796, 0.743, 0.670, and 0.708 for CAR, NLR, PLR, and mGPS, respectively. According to the estimated threshold, high CAR, NLR, PLR, and mGPS were associated with increased one-year mortality (1.7% vs. 11.7%, hazard ratio [HR]: 2.38, 95% CI [2.05, 2.76], P < 0.001 for CAR; 2.2% vs. 10.3%, HR: 1.81, 95% CI [1.62, 2.03], P < 0.001 for NLR; 2.6% vs. 10.5%, HR: 1.86, 95% CI [1.73, 2.01], P < 0.001 for PLR; and 2.3% vs. 16.3%, HR: 2.37, 95% CI [2.07, 2.72], P < 0.001 for mGPS). Conclusions Preoperative CAR, NRL, PLR, and mGPS were associated with postoperative mortality. Our findings may be helpful in predicting mortality after non-cardiac surgery.

Objective: Advanced cervical cancer is still difficult to treat and in the case of recurrent cancer, it is desirable to utilize personalized treatment rather than uniform treatment because the type of recurrence is different for each individual. Therefore, this study aimed to establish a patient-derived organoid (PDO) platform to determine the effects of chemotherapy, radiation therapy, and targeted therapy in cervical cancer. Methods: We established organoids from 4 patients with various types of cervical cancer. The histopathological and gene profiles of these organoid models were compared to determine their characteristics and the maintenance of the patient phenotype. Each type of organoid was also subjected to anticancer drug screening and radiation therapy to evaluate its sensitivity. Results: We established PDOs to recapitulate the main elements of the original patient tumors, including the DNA copy number and mutational profile. We selected 7 drugs that showed growth inhibition in cervical cancer organoids out of 171 using an Food and Drug Administration -approved drug library. Moreover, adenocarcinoma and large-cell neuroendocrine carcinoma showed resistance to radiation therapy. whereas squamous cell carcinoma and villoglandular carcinoma showed a significant response to radiotherapy. Conclusion Our results showed that patient-derived cervical cancer organoids can be used as a platform for drug and radiation sensitivity testing. These findings suggest that patient-derived cervical cancer organoids could be used as a personalized medicine platform and may provide the best treatment options for patients with various subtypes of cervical cancer.

PURPOSE: Follicular thyroid carcinoma (FTC) and papillary thyroid carcinoma (PTC) are two main subtypes of well-differentiated thyroid cancer. Sometimes FTCs present more aggressive features such as vascular invasion. The object of this study was to investigate the clinicopathologic features, prognostic factors and treatment outcome of FTC. METHODS: This retrospective study enrolled 91 patients diagnosed with FTC between November 1994 and October 2008. The clinicopathologic characteristics, treatment outcome and follow up data were analyzed. RESULTS: The median follow-up (f/u) period was 76.1 months. Distant metastases at the time of diagnosis were detected in 12 patients. During the f/u period, one local recurrence and 4 distant metastases developed. Local recurrence or distant metastasis were noticed in 12 out of 19 patients with widely invasive type and 5 out of 36 patients with minimally invasive type with vascular invasion were also noted. The median times to local recurrence or distant metastasis were 59.0 and 34.2 months, respectively. On analysis, according to the clinocopathologic factors, presence of vascular invasion, extrathyroidal extension, invasion to structure, incomplete excision and pathological classification were independent prognostic factors for recurrence or distant metastasis. Disease specific mortality was seen in one patient. CONCLUSION: This study shows that aggressive treatments such as total thyroidectomy followed by radioiodine therapy and close follow-up of patients with minimally invasive type with vascular invasion and widely invasive type of FTC should be considered due to the chance of local recurrence and distant metastasis.

Cholesterol is one of major components of cell membrane and plays a role in vesicular trafficking and cellular signaling. We investigated the effects of cholesterol on matrix metalloproteinase-2 (MMP-2) activation in human dermal fibroblasts. We found that tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) expression and active form MMP-2 (64 kD) were dose-dependently increased by methyl-beta-cyclodextrin (MbetaCD), a cholesterol depletion agent. In contrast, cholesterol depletion-induced TIMP-2 expression and MMP-2 activation were suppressed by cholesterol repletion. Then we investigated the regulatory mechanism of TIMP-2 expression by cholesterol depletion. We found that the phosphorylation of JNK as well as ERK was significantly increased by cholesterol depletion. Moreover, cholesterol depletion-induced TIMP-2 expression and MMP-2 activation was significantly decreased by MEK inhibitor U0126, and JNK inhibitor SP600125, respectively. While a low dose of recombinant TIMP-2 (100 ng/ml) increased the level of active MMP-2 (64 kD), the high dose of TIMP-2 (> or = 200 ng/ml) decreased the level of active MMP-2 (64 kD). Taken together, we suggest that the induction of TIMP-2 by cholesterol depletion leads to the conversion of proMMP-2 (72 kD) into active MMP-2 (64 kD) in human dermal fibroblasts.
