Background: Postoperative pain management is crucial for patients undergoing total knee arthroplasty (TKA). There have been many recent clinical trials on post-TKA peripheral nerve block; however, they have reported inconsistent findings. In this meta-analysis, we aimed to comprehensively analyze studies on post-TKA analgesia to provide evidence-based clinical suggestions. Methods: We performed a computer-based query of PubMed, Embase, the Cochrane Library, and the Web of Science to retrieve related articles using neurothe following search terms: nerve block, nerve blockade, chemodenervation, chemical neurolysis, peridural block, epidural anesthesia, extradural anesthesia, total knee arthroplasty, total knee replacement, partial knee replacement, and others. After quality evaluation and data extraction, we analyzed the complications, visual analogue scale (VAS) score, patient satisfaction, perioperative opioid dosage, and rehabilitation indices. Evidence was rated using the Grading of Recommendations Assessment, Development, and Evaluation approach. Results: We included 16 randomized controlled trials involving 981 patients (511 receiving peripheral nerve block and 470 receiving epidural block) in the final analysis. Compared with an epidural block, a peripheral nerve block significantly reduced complications. There were no significant between-group differences in the postoperative VAS score, patient satisfaction, perioperative opioid dosage, and rehabilitation indices. Conclusions: Our findings demonstrate that the peripheral nerve block is superior to the epidural block in reducing complications without compromising the analgesic effect and patient satisfaction. Therefore, a peripheral nerve block is a safe and effective postoperative analgesic method with encouraging clinical prospects.

Purpose: This study investigated the effects of peripheral neuropathy symptoms, self-care ability, and disturbances to daily life on quality of life (QoL) among gynecological cancer patients undergoing chemotherapy. Methods: The participants included 144 patients with gynecological cancer undergoing anticancer chemotherapy at a tertiary hospital in Seoul, South Korea, from December 1, 2021 to January 28, 2022. Convenience sampling was used to recruit patients who had received 4 or more cycles of chemotherapy using a paclitaxel-platinum regimen, and a self-reported questionnaire was used to collect data. Descriptive statistics, the t-test, analysis of variance, Scheffé test, Pearson correlation coefficients, and multiple regression analysis were performed. Results: Most of the participants had ovarian cancer (70.1%) or endometrial cancer (14.6%), and the most common number of treatment cycles was 6 to 10 (29.2%). The mean QoL (60.83±19.89) was greater than the midpoint. The regression model analyzing the patients' QoL was statistically significant (F=15.38, p<.001) with an explanatory power of 56.7%. Self-care ability (β=.39, p<.001), disturbances to daily life (β=-.38, p<.001), the duration of peripheral neuropathy symptoms (β=2.14, p=.034), and regular exercise (β=-2.12, p=.036) were found to significantly affect QoL. Conclusion: Efforts to improve the self-care ability of gynecological cancer patients who have experienced peripheral neuropathy after receiving chemotherapy and mitigate disturbances to their daily life can improve their QoL. Healthcare professionals should identify peripheral neuropathy symptoms and examine the effects of the symptoms on patients' daily lives. Improving the self-care ability of patients and alleviating their limitations in daily life may improve QoL.

The malignant peripheral nerve sheath tumor is an extremely rare soft tissue sarcoma. It is a highly malignant sarcoma, which is locally invasive, frequently leading to multiple recurrences and eventual metastatic spread. The peak incidence of disease is known to occur sporadically between the age of 20s and 50s, and is usually associated with the neurofibromatosis type I. In human body, the trunk and extremities are the most commonly involved sites, with only 8-14% of all lesions appearing in the head and neck region. We present a case of malignant peripheral nerve sheath tumor involving the right parapharynx in a 48-year-old patient who complained of headaches in the right parietal area and of dysphagia that aggravated over a month. After surgery, tumor was finally diagnosed as malignant peripheral nerve sheath tumor by histopathologic examinations. The authors report a case of malignant peripheral nerve sheath tumor in the right parapharynx with a review of the literature.

Background and Objectives: The colonic epithelial layer is a complex structure consisting of multiple cell types that regulate various aspects of colonic physiology, yet the mechanisms underlying epithelial cell differentiation during development remain unclear. Organoids have emerged as a promising model for investigating organogenesis, but achieving organ-like cell configurations within colonic organoids is challenging. Here, we investigated the biological significance of peripheral neurons in the formation of colonic organoids. Methods and Results: Colonic organoids were co-cultured with human embryonic stem cell (hESC)-derived peripheral neurons, resulting in the morphological maturation of columnar epithelial cells, as well as the presence of enterochromaffin cells. Substance P released from immature peripheral neurons played a critical role in the development of colonic epithelial cells. These findings highlight the vital role of inter-organ interactions in organoid development and provide insights into colonic epithelial cell differentiation mechanisms. Conclusions: Our results suggest that the peripheral nervous system may have a significant role in the development of colonic epithelial cells, which could have important implications for future studies of organogenesis and disease modeling.

The peripheral infection is one of the major causes of maternal death, and although it is preventable through an effective prenatal as well as postnatal care its morbidity is increasing due to bacterial resistant to an effective antibiotics. The primary purpose of this study was to investigate the peripheral morbidity of 949 parturients who were admitted to the Obstetrics and Gynecologic department of Ewha Woman's University Hospital from January 1971 to September 1971. Among the 949 parturients, especially 40 normal parturients were selected (20, control soup was given complete aseptic care during labor and delivery and post delivery: 20, compare group was given the ordinary care practiced during labor and delivery and maternal ward of Ewha Woman's University Hospital) for bacteriologic test on vaginal flora twice, on admission and on complete cervical dilatation of each parturient. The results obtained from this study were as follows; 1. Majority of parturients age were 21 to 35 years old(90.83%), and educational level of 949 parturients was above high school. A large number of parturients socioeconomic level (according to their husbands' job) were moderate. 2, Among the 949 parturients, multipara (55.9%) were a little more than primipara (44. 1%) and 38.84% of parturients had experienced aborition. 3. In deliverty types, normal deliveries (804 cases) were more than cesarean section deliveries (145 cases) The peripheral morbidity after normal deliveries was 0.5%, and cesarean section deliveries, 23.45%. 4. Among 949 parturients incidence of hemorrhage eases (500cc or more bleeding) showed the higher peripheral morbidity (24.86%) than other cases (bleeding less than 500cc, 7.83%). 5. The majority of parturients (81.03%) had teen taking antenatal care, but most of them were taken irregular antenatal care. On the other hand, on admission, the parturients with complication were 30.32%, and their peripheral morbidity showed much higher (7.02%) than those with no complication (2.71%). 6. The incidence of peripheral morbidity in premature ruptured membrane was higher (10.91%) than normal parturienta (1.73%). 7. In the result of aseptic care during labor and delivery and post delivery, the number of cultured bacteria was legs in control group than Compare group (in control group, on admission 17, on complete cervical dilatation 12: in compare group, on admission 21 on complete cervical dilatation 21) . The most common bacteria were Staphylococcus (control group 14 on admission, compare group 16 on admission), and next Streptococcus, E- Coil, Bacillus Subtilis, in order. Also in control group the number. of colony were reduced (43%) more than in Compare group. Transient temperature elevation from 37℃ to 37.4℃ were noted in compare group (50%) than in control group (30%), and there was no one indicated above 38℃. In conclusion, the aseptic care is the test way of preventing peripheral infection as well as decreasing the puerperal morbidity. Therefore the most important nursing care is the aseptic care for each parturient during labor and delivery and peat delivery and also all the instruments must be cleaned and sterilized.

Molecular detection methods such as RT-PCR for detecting breast cancer-associated gene expression in the peripheral blood have the potential to modify breast cancer (BC) staging and therapy. In this regard, we evaluated the potential of erb-B2 molecular marker in BC detection and analyzed the expression of erb-B2 mRNA in the peripheral blood and fresh tissue samples of 50 pretreated female BC patients and 50 healthy females by reverse transcription-PCR (RT-PCR) method. We also assessed the correlation of erb-B2 mRNA marker positivity in peripheral blood and tumor tissue samples with clinical and pathological factors in BC patients in order to evaluate its prognostic value. It was shown that there is a significant difference between healthy females and BC patients with expression of the erb-B2 molecular marker (p<0.01). A significant difference between the expression of erb-B2 in the peripheral blood and tissue samples of BC patients (p<0.01) and the frequency of circulating erb-B2 mRNA expression in peripheral blood and in tissue was detected by RT-PCR. No correlation was found between erb-B2 mRNA expression in blood or tumor tissue samples and lymph node, tumor grade, tumor stage, tumor size, patient's age, ki67, estrogen receptor (ER), progesterone receptor (PGR), P53, and HER-2 status. However, in a small subset of 31 BC patients we found that expression of erb-B2 in peripheral blood or in both peripheral blood and tumor tissue was directly correlated with lympho-vascular invasion and perineural invasion as poor prognostic features. The highest rates of erb-B2 expression in peripheral blood or tumor tissue were in the ER and PR negative and HER-2 positive group. This study suggests that the application of the RT-PCR and immunohistochemical methods for erb-B2 molecular marker detection would provide a higher detection rate, especially in early stage BC.

Purpose - Past research has not given much attention to the roles of consumers' social relationship type in the effects of justice type of service failure recovery alternatives on their satisfaction to the alternative exposed to them. Current research aimed at exploring the moderation role of consumers' social relationship central versus peripheral in the effects of justice types of service failure recovery alternatives on the recovery satisfaction, and this research also explored whether the level of satisfaction to interaction justice-focused alternative are significantly different between the two, their social relationship central and peripheral relationship. Research design, data, and methodology - 2(social relationship central versus peripheral) between-subjects design was employed. 50 participants for each experimental group there were. Participants of each group took forceful steps in choosing one between the procedural justice-focused alternative and the distribution justice-focused alternative. χ²-analysis was used to verify that the number of choosing each alternative becomes different between the two experimental groups, and a one way ANOVA was used to verify that the extent to which participants are satisfied to the alternative chosen by them becomes different between the two groups. Results - The number of participants choosing procedural justice-focused alternative at the group of social relationship central was larger than that at the group of social relationship peripheral, whereas the number of participants choosing distribution justice-focused alternative at the group of social relationship peripheral was larger than that at the group of social relationship central. And the level of satisfaction to procedural justice-focused alternative at the group of social relationship central was higher than that at the group of social relationship peripheral, whereas the level of satisfaction to distribution justice-focused alternative at the group of social relationship peripheral was higher than that at the group of social relationship central. In addition, the level of satisfaction to interaction justice-focused alternative was not significantly different between the two groups. Conclusions - Marketers should give attention to the type of justice when developing alternatives by which consumers' service failure can be recovered. They should suggest procedural justice-focused alternative to consumers under social relationship central, whereas they should develop distribution justice-focused alternative for consumers under social relationship peripheral. And in the process of recovering service failure they also should focus on interaction justice.
