Surgical outcomes of robotic thyroidectomy for thyroid tumors over 4 cm via the bilateral axillo-breast approach.

The study investigated the feasibility of robotic bilateral axillo-breast approach (BABA) thyroidectomy for patients with thyroid tumors larger than 4 cm. BABA thyroidectomy has previously shown safety and effectiveness for thyroid surgeries but lacked extensive data on its application to larger tumors. Between October 2008 and August 2022, there were 74 patients underwent robotic BABA thyroidectomy due to thyroid nodules exceeding 4 cm in size. The mean patient age was 40.3 years. Fine needle aspiration results classified the tumors as benign (50.0%), atypia of undetermined significance (27.0%), follicular neoplasm (16.2%), suspicious for malignancy/malignancy (5.4%), or lymphoma (1.4%). The average tumor size was 4.9 cm, with the majority (85.1%) undergoing thyroid lobectomy, and the rest (14.9%) receiving total thyroidectomy. The mean total operation time was 178.4 min for lobectomy and 207.3 min for total thyroidectomy. Transient vocal cord palsy (VCP) was found in 3 patients (4.1%), and there was no permanent VCP. Among patients who underwent total thyroidectomy, transient hypoparathyroidism was observed in three (27.2%), and permanent hypoparathyroidism was observed in one (9.1%). There were no cases of open conversion, tumor spillage, bleeding, flap injury, or tumor recurrence. In conclusion, robotic BABA thyroidectomy may be a safe treatment option for large-sized thyroid tumors that carries no significant increase in complication rates.

Effect of blind versus fluoroscopic guidance epidural blood patch in patients with intracranial hypotension.

Epidural blood patch (EBP)-the most effective treatment for intracranial hypotension (IH)-can be performed using the blind technique in the lateral position or under fluoroscopic guidance in the prone position. This study aimed to compare the effectiveness of EBP in patients with spontaneous intracranial hypotension (sIH) and iatrogenic intracranial hypotension (iIH) when performed with the blind technique in the lateral decubitus position or fluoroscopic guidance in the prone position. We reviewed IH patients who underwent EBP between January 2015 and September 2019 in a single hospital and divided them into two groups according to the type of IH. Of the 84 included patients, 36 had sIH and 48 had iIH. We compared the effectiveness of EBP using the two methods in each group. There was no significant difference in the effect of EBP between the patients with iIH (p > 0.05). For patients with sIH, fluoroscopic guidance in the prone position technique showed better improvement than the blind technique in the lateral decubitus position (p < 0.05). We observed similar outcomes after blind EBP versus fluoroscopic guidance EBP in patients with iIH. However, procedure-dependent differences were observed in patients with sIH. For patients with sIH, it would be effective to consider fluoroscopic EBP first. Further study is needed to investigate interactions between method of EBP and other factors that affect the effectiveness of EBP.

Factors affecting work-related non-fatal injuries among aged workers in South Korea.

Introduction: The objective of this paper is to investigate whether an aging workforce is associated with an increase in work-related non-fatal injuries and to explore the underlying reasons for this potential increase. Methods: Aged workers were defined as those who were at least 55-years-old. Work-related non-fatal injuries were assessed in aged and young workers who were registered with the workers' compensation system from 2017 to 2021 of South Korea. Results: The mean estimated rate of work-related non-fatal injuries of aged workers (0.88/100) was about 2.5-times higher than that of younger workers (0.35/100). Most work-related non-fatal injuries in the older adults were in individuals working in the "construction sector" (36.0%), those with "elementary occupations (unskilled workers)" (45.0%), and those with employment status of "daily worker" (44.0%). "Trip & slip" (28.7%) and "falling" (19.6%) were more frequent types of work-related non-fatal injuries in aged workers relative to young workers. The category of "buildings, structures, and surfaces" was a more frequent cause of work-related non-fatal injuries in aged workers than young workers. Discussion: The incidence of non-fatal work-related injuries is higher among aged workers compared to their younger counterparts. The increased occurrence of aged workers participating in precarious employment and jobs, along with the greater physical vulnerability, is likely the cause of their higher rate of work-related non-fatal injuries.

Comparative outcomes and prognostic indicators in adrenalectomy for adrenal metastasis.

PURPOSE: The indications for adrenalectomy and feasibility of laparoscopic adrenalectomy for adrenal metastasis are controversial. This study aimed to compare the surgical outcomes between open adrenalectomy (OA) and laparoscopic adrenalectomy (LA) and to evaluate the prognostic factors for oncological outcomes of adrenal metastasis. MATERIALS AND METHODS: We conducted a retrospective chart review of 141 consecutive patients who underwent adrenalectomy for adrenal metastasis at Seoul National University Hospital from April 2005 to February 2021. Surgical and oncological outcomes were compared between OA and LA. RESULTS: OA was performed in 95 (67.4%) patients, and 46 (32.6%) patients underwent LA. Among the patients who underwent adrenalectomy without adjacent organ resection for adrenal tumors less than 8 cm, LA was associated with a shorter operation time (100.1 ± 48.8 vs. 158.6 ± 81.2, P = 0.001), less blood loss (94.8 ± 93.8 vs. 566.8 ± 1156.0, P = 0.034), and a shorter hospital stay (3.7 ± 1.3 vs. 6.9 ± 5.8, P = 0.003). For locoregional recurrence-free survival (LRRFS), on multivariate analysis, a positive pathological margin (hazard ratio [HR]: 5.777, P = 0.002), disease activity at the primary site (HR: 6.497, P = 0.005), other metastases (HR: 4.154, P = 0.015), and a relatively larger tumor size (HR: 1.198, P = 0.018) were significantly associated with poor LRRFS. Multivariate analysis indicated that metachronous metastasis (HR: 0.51, P = 0.032) was associated with a longer overall survival (OS), whereas a positive pathological margin (HR: 2.40, P = 0.017), metastases to other organs (HR: 2.08, P = 0.025), and a relatively larger tumor size (HR: 1.11, P = 0.046) were associated with a shorter OS. CONCLUSIONS: LA is a feasible treatment option for adrenal metastasis in selected patients. The pathological margin, metastases to other organs, and tumor size should be considered in adrenalectomy for adrenal metastasis.

The effect of perineural injection therapy on neuropathic pain: a retrospective study.

Background: Among the various pain-related diseases that can be encountered at the clinic, there is a neuropathic pain that is difficult to treat. Numerous methods have been proposed to treat neuropathic pain, such as taking medication, nerve block with lidocaine, or neurolysis with alcohol or phenol. Recently, a method of perineural injection using dextrose instead of lidocaine was proposed. This study was designed to compare the effects of perineural injection therapy (PIT) with buffered 5% dextrose or 0.5% lidocaine on neuropathic pain. Methods: The data were collected from the database of pain clinic from August 1st, 2019 to December 31st, 2022 without any personal information. The inclusion criteria were patients diagnosed with postherpetic neuralgia (PHN), trigeminal neuralgia (TN), complex regional pain syndrome (CRPS), or peripheral neuropathy (PN), and patients who had undergone PIT with buffered 5% dextrose (Dextrose group) or 0.5% lidocaine (Lidocaine group) for pain control. The data of patients, namely sex, age, and pain score (numerical rating scale, NRS) were collected before PIT. The data of NRS, side effects, and satisfaction grade (excellent, good, fair, or poor) were collected one week after each of the four PIT, and two weeks after the last PIT. Results: Overall, 112 subjects were enrolled. The Dextrose group included 89 and Lidocaine group included 23 patients. Because the number of patients in the Lidocaine group was too small to allow statistical analysis, the trend in Lidocaine group was just observed in each disease. There were no significant side effects except for a few bruise cases on the site of injection in all groups. The NRS in most Dextrose groups except CRPS were reduced significantly; however, the Lidocaine group showed a trend of pain reduction only in PHN. The Dextrose group except CRPS showed increased satisfaction two weeks after the final PIT. Conclusion: From the results, it is suggested that PIT with buffered 5% dextrose may have a good effect for neuropathic pain without any side effect except for patients with CRPS. This may offer a window into a new tool that practitioners can employ in their quest to help patients with neuropathic pain.

Sustainable Production of Shinorine from Lignocellulosic Biomass by Metabolically Engineered Saccharomyces cerevisiae.

Mycosporine-like amino acids (MAAs) have been used in cosmetics and pharmaceuticals. The purpose of this work was to develop yeast strains for sustainable and economical production of MAAs, especially shinorine. First, genes involved in MAA biosynthetic pathway from Actinosynnema mirum were introduced into Saccharomyces cerevisiae for heterologous shinorine production. Second, combinatorial expression of wild and mutant xylose reductase was adopted in the engineered S. cerevisiae to facilitate xylose utilization in the pentose phosphate pathway. Finally, the accumulation of sedoheptulose 7-phosphate (S7P) was attempted by deleting transaldolase-encoding TAL1 in the pentose phosphate pathway to increase carbon flux toward shinorine production. In fed-batch fermentation, the engineered strain (DXdT-M) produced 751 mg/L shinorine in 71 h. Ultimately, 54 mg/L MAAs was produced by DXdT-M from rice straw hydrolysate. The results suggest that shinorine production by S. cerevisiae might be a promising process for sustainable production and industrial applications.

An Entropy Analysis-Based Window Size Optimization Scheme for Merging LiDAR Data Frames.

LiDAR is a useful technology for gathering point cloud data from its environment and has been adapted to many applications. We use a cost-efficient LiDAR system attached to a moving object to estimate the location of the moving object using referenced linear structures. In the stationary state, the accuracy of extracting linear structures is low given the low-cost LiDAR. We propose a merging scheme for the LiDAR data frames to improve the accuracy by using the movement of the moving object. The proposed scheme tries to find the optimal window size by means of an entropy analysis. The optimal window size is determined by finding the minimum point between the entropy indicator of the ideal result and the entropy indicator of the actual result of each window size. The proposed indicator can describe the accuracy of the entire path of the moving object at each window size using a simple single value. The experimental results show that the proposed scheme can improve the linear structure extraction accuracy.

The Association of Low Skeletal Muscle Mass with Complex Distal Radius Fracture.

Objectives: Sarcopenia is a skeletal muscle loss disease with adverse outcomes, including falls, mortality, and cardiovascular disease (CVD) in older patients. Distal radius fractures (DRF), common in older people, are strongly related to falls. We aimed to investigate the correlation between DRF and low skeletal muscle mass, which strongly correlated to sarcopenia. Methods: We performed a retrospective review of data from patients diagnosed with or without DRF in our institute between 2015 and 2020. Finally, after propensity score matching, data from 115 patients with and 115 patients without DRF were used for analyses. Multivariate logistic regression analysis was performed for sex, body mass index (BMI), the presence of low skeletal muscle mass, bone quality measured by dual-energy X-ray absorptiometry (DXA), and comorbidities (diabetes mellitus, CVD). Results: We found that female sex (odds ratio = 3.435, p = 0.015), CVD (odds ratio = 5.431, p < 0.001) and low skeletal muscle mass (odds ratio = 8.062, p = 0.001) were significant predictors for DRF. BMI and osteoporosis were not statistically significantly related to DRF. Conclusions: Women with low skeletal muscle mass and CVD may be more responsible for DRF than osteoporosis.

The Applicability of Virtual Reality-Based Training for Controlling Anger in Aggressive Individuals.

Because a failure of anger control leads to emotional and social problems, appropriate anger management may be important for social well-being. Virtual reality (VR) may potentially be effectively utilized in anger management, and this study aimed to verify the applicability of the VR-based anger control training program. The data obtained by having 60 young male participants divided into 2 groups, the high aggression group and the low aggression group, based on their Aggression Questionnaire scores to execute this program were analyzed. The program consisted of "Anger Exposure Training" for provoking anger and facilitating anger control and "Mindfulness Training" for providing the meditation experience for controlling anger. The anger scores and comfort scores obtained from these tasks, respectively, were analyzed for differences between the groups and between the experimental conditions. The anger regulation and comfort enhancement rates were analyzed for correlations with psychological variables. In Anger Exposure Training, the anger scores in angry expression were reduced in managed expression of anger in both groups. In Mindfulness Training, meditation increased comfort score as well in both groups, and the comfort enhancement rates were negatively correlated with the levels of self-differentiation and open communication with mother only in the high aggression group. These results indicate that the VR environments can provide an effective means of trainings for managing anger. Therefore, further research on the effectiveness of the VR-based anger control training program is worthy conducting in individuals who express excessive aggression.

Paradoxical carbon dioxide embolism during laparoscopic hepatectomy without intracardiac shunt: A case report.

BACKGROUND: Laparoscopic hepatectomy has recently become popular because it results in less bleeding than open hepatectomy. However, CO2 embolism occurs more frequently. Most CO2 embolisms during laparoscopic surgery are self-resolving and non-symptomatic; however, severe CO2 embolism may cause hypotension, cyanosis, arrhythmia, and cardiovascular collapse. In particular, paradoxical CO2 embolisms are highly likely to cause neurological deficits. We report a case of paradoxical CO2 embolism found on transesophageal echocardiography (TEE) during laparoscopic hepatectomy, although the patient had no intracardiac shunt. CASE SUMMARY: A 71-year-old man was admitted for laparoscopic left hemihepatectomy. During left hepatic vein ligation, the inferior vena cava was accidentally torn. We observed a sudden drop in oxygen saturation to 85%, decrease in systolic blood pressure (SBP) below 90 mmHg, and reduction in end-tidal CO2 to 24 mmHg. A "mill-wheel" murmur was auscultated over the precordium. The fraction of inspired oxygen was increased to 100% with 5 cmH2O of positive end-expiratory pressure (PEEP) and hyperventilation was maintained. Norepinephrine infusion was increased to maintain SBP above 90 mmHg. A TEE probe was inserted, revealing gas bubbles in the right side of the heart, left atrium, left ventricle, and ascending aorta. The surgeon reduced the pneumoperitoneum pressure from 17 to 14 mmHg and repaired the damaged vessel laparoscopically. Thereafter, the patient's hemodynamic status stabilized. The patient was transferred to the intensive care unit, recovering well without complications. CONCLUSION: TEE monitoring is important to quickly determine the presence and extent of embolism in patients undergoing laparoscopic hepatectomy.

The anti-nociceptive effect of BPC-157 on the incisional pain model in rats.

Background: The pentadecapeptide BPC-157 has been shown to have anti-inflammatory and wound healing effects on multiple target tissues and organs. Peptides have potent anti-inflammatory effects on periodontal tissues in rats with periodontitis. Few studies have investigated the effect of BPC-157 on pain after dental procedures or oral surgeries. The purpose of the present study was to investigate the antinociceptive effects of BPC-157 on postoperative incisional pain in rats. Methods: Sprague-Dawley rats were randomly divided into five groups: control (saline with the same volume), BPC10 (10 µg/kg of BPC-157), BPC20 (20 µg/kg of BPC-157), BPC40 (40 µg/kg of BPC-157), and morphine (5 mg/kg of morphine). A 1-cm longitudinal incision was made through the skin, fascia, and muscle of the plantar aspect of the hind paw in isoflurane-anesthetised rats. Withdrawal responses were measured using von Frey filaments at 0, 2, 6 h and 4, 7 d after incision. The formalin test was also performed to differentiate its anti-nociceptive effect from an inflammatory reaction or central sensitization. Pain behavior was quantified periodically in phases 1 and 2 by counting the number of flinches in the ipsilateral paw after injection with 30 µL of 5% formalin. Results: The threshold of mechanical allodynia was significantly increased in the BPC10, BPC20, BPC40 and morphine groups compared with that in the control group at 2 h. These increasing thresholds then returned to the levels of the control group. The BPC-157 group showed a much higher threshold at 4 days after incision than the control group. The thresholds of the BPC groups, except the morphine group, were normalized 7 days after incision.The flinching numbers of the BPC10, BPC20, BPC40 and morphine groups were significantly decreased in phase 1, but there was no decrease in the BPC-157 groups except the morphine group in phase 2. Conclusions: BPC-157 was effective only for a short period after incision. It was also effective during phase 1 but not during phase 2, as determined by the formalin test. BPC-157 might have a short antinociceptive effect, even though it has anti-inflammatory and wound healing effects.

A Counter Prechop Technique Using a Modified Universal Prechopper in Combination with or without Using a Universal Chopper.

PURPOSE: To introduce an alternative prechop technique without or with the use of a modified universal chopper (AE-2591, HI Kim chopper, ASICO, Inc. USA). METHODS: Patients who underwent cataract surgery using the phaco-chop technique and the modified prechop technique have been grouped and reviewed retrospectively. Endothelial cell count (ECC) and central corneal thickness (CCT) measured 7 days pre-operatively, and 1 month and 3 months post-operatively, were compared between the two groups. In modified prechop technique, a narrow 1.7 mm neck prechopper (AE-4298, HI Kim-Inamura chopper, ASICO, Inc., USA) was used with universal chopper (AE-2591, HI Kim chopper, ASICO, Inc., USA) as an additional device for grade 4 and above cataracts or without it for grade 2 to 3 cataracts. Details of the surgical technique is further described in the Method section. RESULTS: A total of 104 eyes in the modified prechop group and 97 eyes in the phaco-chop group were enrolled in the study. Pre-operative nuclear opacity, ECC, and CCT as well as post-operative ECC (absolute value and the loss) and CCT (absolute value and the change) throughout the follow-up between the two groups did not show statistically significant differences. CONCLUSION: Counter prechop technique using the modified prechopper and universal chopper is a safe, easy, and versatile surgical technique that can be applied broadly in a wide range of cases with various complexities, including LOCS lll N1 to N6 nuclei, hypermature cataracts, small pupils, and fragile suspensory zonular ligaments, with post-operative result not inferior to that of the conventional technique.

TMI-1, TNF-α-Converting Enzyme Inhibitor, Protects Against Paclitaxel-Induced Neurotoxicity in the DRG Neuronal Cells In Vitro.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) negatively impacts cancer survivors' quality of life and is challenging to treat with existing drugs for neuropathic pain. TNF-α is known to potentiate TRPV1 activity, which contributes to CIPN. Here, we assessed the role of TMI-1, a TNF-α-converting enzyme inhibitor, in paclitaxel (PAC)-induced neurotoxicity in dorsal root ganglion (DRG) cells. Materials and Methods: Immortalized DRG neuronal 50B11 cells were cultured and treated with PAC or PAC with TMI-1 following neuronal differentiation. Cell viability, analysis of neurite growth, immunofluorescence, calcium flow cytometry, western blotting, quantitative RT-PCR, and cytokine quantitation by ELISA were performed to determine the role of TMI-1 in neurotoxicity in neuronal cells. Results: PAC administration decreased the length of neurites and upregulated the expression of TRPV1 in 50B11 cells. TMI-1 administration showed a protective effect by suppressing inflammatory signaling, and secretion of TNF-α. Conclusion: TMI-1 partially protects against paclitaxel-induced neurotoxicity by reversing the upregulation of TRPV1 and decreasing levels of inflammatory cytokines, including TNF-α, IL-1ß, and IL-6 in neuronal cells.

Increased Brain-Derived Neurotrophic Factor Levels in Cerebrospinal Fluid During the Acute Phase in TBI-Induced Mechanical Allodynia in the Rat Model.

BACKGROUND: The present study aimed to develop a rat model for mechanical allodynia after traumatic brain injury (TBI) and to investigate the expression of brain-derived neurotrophic factor (BDNF) in the cerebrospinal fluid (CSF) using this model. METHODS: A total of 180 rats were randomly allocated into three groups: a control group (group C), a sham-operated group (group S), and a controlled cortical impact induced TBI group (group T), 60 in each group. Von Frey test was performed to evaluate mechanical withdrawal thresholds. An enzyme-linked immunosorbent assay was performed to quantify BDNF level in CSF. RESULTS: The 50% withdrawal thresholds of group T were lower than those of group C and group S at all measuring points except for the preoperative period (P = 0.026, <0.001, and <0.001 for POD1, POD7, and POD14, respectively). The BDNF level of group T was higher than those of group C and group S at POD1 (P = 0.005). CONCLUSION: Upregulation of the BDNF expression in CSF was observed in rats who developed mechanical allodynia on the day after TBI. Based on our findings, to elucidate the relationship between TBI-induced neuropathic pain and BDNF expression in CSF, further research should be carried out through a multifaceted approach to a broad spectrum of pain behavior models.

Diagnosis and management of ophthalmic zoster sine herpete accompanied by cervical spine disc protrusion: A case report.

BACKGROUND: Zoster sine herpete (ZSH) can be misdiagnosed because there are no typical vesicular eruptions characterized by a dermatomal distribution. However, incorrect treatment due to a misdiagnosis can lead to severe pain and fatal complications. CASE SUMMARY: A 75-year-old woman complained of sudden onset right shoulder pain and atypical headache. After 18 d, sudden hearing loss occurred in the left ear. In serology tests conducted after the onset of hearing loss, varicella-zoster virus IgM was positive. She had no history of a rash or trauma. Under the suspicion of ZSH, antiviral treatment and stellate ganglion block were administered four times, and the pain was effectively controlled. CONCLUSION: Early diagnosis and treatment of ZSH can help not only by reducing pain but also by preventing fatal complications.

Transient involuntary movement disorder after spinal anesthesia: A case report.

BACKGROUND: Spinal anesthesia is commonly used for various surgeries. While many complications occur after induction of spinal anesthesia, involuntary movement is an extremely rare complication. CASE SUMMARY: Herein, we report the case of a 54-year-old healthy male patient who experienced involuntary movements after intrathecal injection of local anesthetics. This patient had undergone metal implant removal surgery in both the lower extremities; 7 h after intrathecal hyperbaric bupivacaine administration, involuntary raising of the left leg began to occur every 2 min. When the movement disorder appeared, the patient was conscious and cooperative. No other specific symptoms were noted in the physical examination conducted immediately after the involuntary leg raising started; moreover, the patient's motor and sensory assessments were normal. The symptom gradually subsided. Twelve hours after the symptom first occurred, its frequency decreased to approximately once every three hours. Two days postoperatively, the symptoms had completely disappeared without intervention. CONCLUSION: Anesthesiologists should be aware that movement disorders can occur after spinal anesthesia and be able to identify the cause, such as electrolyte imbalance or epilepsy, since immediate action may be required for treatment. Furthermore, it is crucial to know that involuntary movement that develop following spinal anesthesia is mostly self-limiting and may not require additional costly examinations.

Longitudinal Study of Mycobacterium avium Subsp. paratuberculosis Antibody Kinetics in Dairy Cattle Using Sera and Milk Throughout the Lactation Period.

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of Johne's disease in dairy cattle populations around the world. The objective of this study was to evaluate MAP antibody kinetics in serum and milk samples throughout the lactation period in dairy cattle. The samples were collected simultaneously from eight MAP-positive and two healthy MAP-negative (control group) cows. The MAP antibody was detected by using serum and milk ELISA. The serum and milk MAP antibody titers fluctuated between the positive and negative cut-off values in this study. Specifically, cattle with low MAP antibody titer (<100) showed fluctuation between the cut-off values. Variable changes of MAP antibody titer were also observed after parturition. Between the serum and milk MAP antibody titers, there was a positive correlation (R2 = 0.5358) observed throughout the assessment period. The milk MAP ELISA test had low diagnostic performance in cows with low MAP titer due to its weak correlation (R2 = 0.0198). Finally, this study suggest that the periodic MAP ELISA test is recommended for the application of Johne's eradication program due to the fluctuating nature of MAP antibody kinetics.

Concealed congenital long QT syndrome during velopharyngeal dysfunction correction: a case report.

The congenital long QT syndrome (LQTS) is an inherited cardiac disorder characterized by increased QT intervals and a tendency to experience ventricular tachycardia, which can cause fainting, heart failure, or sudden death. A 4-year-old female patient undergoing velopharyngeal correction surgery under general anesthesia suddenly developed Torsades de pointes. Although the patient spontaneously resolved to sinus rhythm without treatment, subsequent QT prolongation persisted. Here, we report a case of concealed LQTS with a literature review.

Gradual aggravation of idiopathic glossopharyngeal neuralgia due to chronic tonsillitis: A case report.

RATIONALE: Glossopharyngeal neuralgia (GPN) is a rare type of neuralgia. Depending on the cause, it is classified as idiopathic GPN and secondary GPN. Secondary GPN can also be caused by a mass effect or inflammation of the tonsils, the innervation area of glossopharyngeal nerve. PATIENT CONCERNS: The patient was diagnosed idiopathic GPN 8 years ago. The patient had intermittent pain, but the pain was well controlled. From 5 months ago, the pain gradually worsened, the patient complained severe pain which impaired chewing and swallowing function. DIAGNOSES: Idiopathic GPN, secondary GPN, chronic tonsillitis INTERVENTIONS:: Percutaneous glossopharyngeal nerve block, glossopharyngeal neurolysis, and pulsed radiofrequency neuromodulation of glossopharyngeal nerve were performed. After the diagnosis of tonsillitis, antibiotic therapy was performed OUTCOMES:: Two weeks after the antibiotic treatment, the pain decreased simultaneously with the patient's tonsillitis recovery. LESSONS: In a Patient who had already been diagnosed with idiopathic GPN, both pain control and its cause should be considered when the pain is aggravated.

Inflexible eye fixation pattern in schizophrenia affecting decision-making on daily life.

Patients with schizophrenia have difficulties in real life due to impairment in ability to make decisions. The purpose of this study was to elucidate the relationship between impaired decision-making processes with real life stimuli and abnormal eye gaze patterns in patients with schizophrenia. Each of 23 patients with schizophrenia and 23 healthy controls performed an apparel purchase decision task including the influencing factors such as preference, fit, and price, during which the eye gaze was traced. Fixation time and fixation time ratio on areas of interest, which were set for participant faces and clothing, were compared between the two groups. Compared with controls, patients made purchase decisions at a higher rate and showed significantly shorter fixation time on clothing in the preference, fit, and price phases and on faces in the purchase phase. Fixation time ratio of face over clothing did not change over purchase decisions in patients, whereas controls showed significantly higher fixation time ratio in not-to-buy decisions than in to-buy decisions. These results suggest that aberrant decision-making behaviors in patients with schizophrenia are closely related to inflexible visual information gathering patterns because they apportion the same amount of attention to objects regardless of purchase intention.
