Clinicopathological features of small T1 colorectal cancers

BACKGROUND

Although small colorectal neoplasms (< 10 mm) are often easily resected endoscopically and are considered to have less malignant potential compared with large neoplasms (≥ 10 mm), some are invasive to the submucosa.

AIM

To clarify the clinicopathological features of small T1 colorectal cancers.

METHODS

Of 32025 colorectal lesions between April 2001 and March 2018, a total of 1152 T1 colorectal cancers resected endoscopically or surgically were included in this study and were divided into two groups by tumor size: a small group (< 10 mm) and a large group (≥ 10 mm). We compared clinicopathological factors including lymph node metastasis (LNM) between the two groups.

RESULTS

The incidence of small T1 cancers was 10.1% (116/1152). The percentage of initial endoscopic treatment in small group was significantly higher than in large group (< 10 mm 74.1% vs ≥ 10 mm 60.2%, P < 0.01). In the surgical resection cohort (n = 798), the rate of LNM did not significantly differ between the two groups (small 12.3% vs large 10.9%, P = 0.70). In addition, there were also no significant differences between the two groups in pathological factors such as histological grade, vascular invasion, or lymphatic invasion.

CONCLUSION

Because there was no significant difference in the rate of LNM between small and large T1 colorectal cancers, the requirement for additional surgical resection should be determined according to pathological findings, regardless of tumor size.

Enhancing predictive accuracy in hypertriglyceridemia-induced acute pancreatitis: Role of red cell distribution width and prospective studies

This letter addresses the study titled "Red cell distribution width: A predictor of the severity of hypertriglyceridemia-induced acute pancreatitis" by Lv et al published in the World Journal of Experimental Medicine. The study offers a valuable analysis of red cell distribution width (RDW) as a predictive marker for persistent organ failure in patients with hypertriglyceridemia-induced acute pancreatitis. The study results suggest that RDW, combined with the Bedside Index for Severity in Acute Pancreatitis score, could enhance the predictive accuracy for severe outcomes. Further investigation into the role of RDW in different severities of acute pancreatitis is recommended. Additionally, the need for large-scale and multicenter prospective studies to validate these findings is emphasized.

Nosocomial infection and spread of SARS-CoV-2 infection among hospital staff, patients and caregivers

BACKGROUND

There are difficulties in diagnosing nosocomial transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in hospital settings. Furthermore, mortality of cases of nosocomial infection (NI) with SARS-CoV-2 is higher than that of the general infected population. In the early stage of the pandemic in Taiwan, as patients were not tested for SARS-CoV-2 at admission, NIs often go undetected. Strictly applying the systematic polymerase chain reaction (PCR) screening, as a standard infection control measure was subsequently implemented to reduce NI incidence. However, evidence on risk factors for SARS-CoV-2 NIs among healthcare workers (HCWs) and caregivers is limited.

AIM

To assess NI incidence of SARS-CoV-2 among hospital staff, hospitalized patients, and caregivers, and the transmission routes of clusters of infection.

METHODS

This descriptive retrospective analysis at our hospital from May 15 to August 15, 2021 included data on 132 SARS-CoV-2 NIs cases among hospital staff, inpatients, and caregivers who previously tested negative but subsequently identified with a positive SARS-CoV-2 reverse transcriptase-PCR (RT-PCR) test results, or a hospital staff who tested positive following routine SARS-CoV-2 RT-PCR test. Chi-square tests were performed to compare the differences between hospital staff and private caregivers, and between clusters and sporadic infections.

RESULTS

Overall, 9149 patients and 2005 hospital staff members underwent routine SARS-CoV-2 RT-PCR testing, resulting in 12 confirmed cluster and 23 sporadic infections. Among the index cases of the clusters, three (25%) cases were among hospital staff and nine (75%) cases were among other contacts. Among sporadic infections, 21 (91%) cases were among hospital staff and two (9%) cases were among other contacts (P < 0.001). There was an average of 8.08 infections per cluster. The secondary cases of cluster infection were inpatients (45%), hospital staff (30%), and caregivers (25%). Private caregivers constituted 27% and 4% of the clusters and sporadic infections, respectively (P = 0.024); 92.3% of them were infected in the clusters. The mortality rate was 0.0%.

CONCLUSION

The incidence of SARS-CoV-2 infection was relatively high among private caregivers, indicating a need for infection control education in this group, such as social distancing, frequent hand-washing, and wearing PPE.

Anatomical basis for pancreas transplantation via isolated splenic artery perfusion: A literature review

The variability of vascular anatomy of the pancreas underlines the difficulty of its transplantation. Research regarding the consistency of anatomical variations shows splenic arterial dominance in most cases. This can significantly improve transplantation success. A systematic literature review was performed according to the quality standards described in the AMSTAR measurement tool and the PRISMA guidelines. We valuated existing literature regarding the vascularization and blood perfusion patterns of the pancreas in terms of dominance and variability. The collected data was independently analyzed by two researchers. Variance of vascular anatomy was seen to be underreported in literature, though significant findings have been included and discussed in this study, providing valuable insight into the dynamics of pancreatic perfusion and feasibility of transplantation on several different supplying arteries. The splenic artery (SA) has a high percentage of consistency in all found studies (over 90%). High frequency of anastomoses between arterial pools supplying the pancreas can mediate sufficient blood supply through a dominant vessel, such as the SA, which is present in most cases. Pancreatic transplantation with isolated SA blood supply can provide sufficient arterial perfusion of the pancreas for stable transplant viability due to high anatomical consistency of the SA and vast communications with other arterial systems.

Multimodal emotion recognition in the metaverse era: New needs and transformation in mental health work

This editorial comments on an article recently published by López del Hoyo et al. The metaverse, hailed as "the successor to the mobile Internet", is undoubtedly one of the most fashionable terms in recent years. Although metaverse development is a complex and multifaceted evolutionary process influenced by many factors, it is almost certain that it will significantly impact our lives, including mental health services. Like any other technological advancements, the metaverse era presents a double-edged sword for mental health work, which must clearly understand the needs and transformations of its target audience. In this editorial, our primary focus is to contemplate potential new needs and transformation in mental health work during the metaverse era from the perspective of multimodal emotion recognition.

Outbreak of methanol-induced optic neuropathy in early COVID-19 era; effectiveness of erythropoietin and methylprednisolone therapy

BACKGROUND

Methanol is a highly toxic, non-potable alcohol. Outbreaks of methanol toxicity occur due to its fraudulent addition to alcoholic beverages as a cheaper substitute for ethanol. Recently, alongside the coronavirus disease 2019 (COVID-19) pandemic, rumors circulated on social media that consuming alcohol can prevent or cure the virus, leading to a COVID-19 and methanol-induced optic neuropathy (MON) syndemic.

AIM

To investigate the impact of erythropoietin (EPO) on the outcomes of patients diagnosed with MON.

METHODS

In this prospective study, 105 patients presenting with acute bilateral visual loss secondary to methanol intoxication were enrolled from March to May 2020 at Farabi Eye Hospital. A comprehensive ocular examination was conducted for all participants. Recombinant human EPO and methylprednisolone were administered intravenously to all patients for three consecutive days.

RESULTS

The mean age of the participants was 39.9 years (± 12.6). Ninety-four patients were male and eleven were female. The mean pre-treatment best corrected visual acuity (BCVA) improved from 2.0 ± 0.86 to 1.39 ± 0.69 logarithm of the minimum angle of resolution post-treatment (P < 0.001), with significant improvement observed in all age categories and genders (P < 0.001). Visual acuity improvement was also significant regardless of whether the patient presented before or after 72 h (P < 0.001), and the post-treatment BCVA remained significant at all monthly follow-up visits (P < 0.001).

CONCLUSION

EPO and methylprednisolone therapy have been shown to be effective in improving visual outcomes in patients with MON when administrated within the first month of exposure. Public awareness efforts are necessary to prevent further outbreaks of methanol toxicity in the current COVID-19 era.

Grounded theory qualitative approach from Foucault's ethical perspective: Deconstruction of patient self-determination in the clinical setting

This paper aims to explain the construction of the autonomous subject from Foucault's ethical perspective for the qualitative analysis of interprofessional relationships, patient-professional relationships, and moral ethics critique. Foucault tried to break loose from the self, which is merely the result of a biopolitical subjectivation and constituted an interpersonal level. From this, different elements involved in the decision-making capacity of patients in a clinical setting were analysed. Firstly, the context in which decision-making occurs has been explained, distinguishing between traditional practices involved in self-care and the more modern conceptions that make certain possible transformations. Secondly, an attempt is made to explain the formation of the medicalisation of society using the transformations of what Foucault called "techniques of the self". Finally, the ethical framework for a subject's "self-creation", insisting more on the exercises of self-subjectivation, reinforcing the ethics of the self by itself, the "care of the self", has been explained. The role of the patient is understood as an autonomous subject to the extent that the clinical institution and the professionals involved comprehend how the patient's autonomy in the clinical environment is constituted. All these elements could generate grounded theory on the qualitative methodology of this phenomenon. The current ethical model based on universal principles is not useful to provide a capacity for patients decision-making, relegating to the background their opinions and beliefs. Consequently, a new ethical perspective emerges that aims to return the patient to the fundamental axis of attention.

Endoscopic retrograde appendicitis treatment for periappendiceal abscess: A case report

BACKGROUND

Acute appendicitis is the most common abdominal emergency. At present, the main treatments for periappendiceal abscess include antibiotics and surgery. However, the complications and mortality of emergency surgery are high. The preferred therapy is conservative treatment with antibiotics first, ultrasound-guided puncture drainage or surgical treatment is followed when necessary. Endoscopic retrograde appendicitis therapy (ERAT) for acute uncomplicated appendicitis have been proved clinically effective, but it is rarely used in periappendiceal abscess.

CASE SUMMARY

We report a patient admitted to hospital because of "right lower abdominal pain for six days". The computerized tomography (CT) of patient showed that appendicitis with fecaliths and abscess in the pelvis. The patient was treated by CT-guided puncture and drainage of abdominal abscess combined with ERAT to remove appendiceal fecaliths, irrigation and stent placement.

CONCLUSION

The patient did not receive surgery because of impoverished family. Abdominal pain did not recur during the follow-up period. This case confirms the value of ERAT in the treatment of periappendiceal abscess.

Signet ring cell carcinoma hidden beneath large pedunculated colorectal polyp: A case report

BACKGROUND

Large pedunculated colorectal polyps are not frequent among colonic polyps. We present a clinical case of a large pedunculated colorectal polyp with signet ring cell cancer infiltrating the submucosa and lymph node invasion in a patient who ultimately underwent additional surgery. Clinicians should attach importance to pedunculated colorectal polyps and choose the most appropriate therapy.

CASE SUMMARY

A 52-year-old female farmer underwent routine screening colonoscopy and denied constipation, diarrhea, hematochezia, or other gastrointestinal symptoms. Her past medical history and general biochemical examination results were unremarkable. During the colonoscopy, a 25-mm pedunculated polyp in the sigmoid colon was identified. The superficial epithelium was macroscopically congestive, rough, and granular, showing characteristic features of adenoma. We first ligated the root of the pedunculated polyp using nylon loops as well as a titanium clip. Histopathological examination revealed high-grade intraepithelial neoplasia of the tumor surface and a negative margin with signet ring cell adenocarcinoma infiltrating the submucosal layer. The deepest infiltration was approximately 0.9 cm from the tumor surface and 0.55 cm from the stratum basale. We performed radical resection of the left colon with lymph node dissection after two weeks. The lesion was completely resected, and pathological assessment revealed signet ring cell adenocarcinoma infiltrating the submucosal layer as well as lymph node invasion (stage PT1N1M0 and grade IIIA in pathological grading, NRAS-, BRAF V600E-, KRAS-).

CONCLUSION

This case highlights the importance of paying attention to the malignancy of large pedunculated polyps. Polyps or adenomas removed via endoscopy must be evaluated histologically. Even if adenomas may be fragile, endoscopy doctors should still remove polyps as completely as possible and choose perpendicular sections through the stalk and base to fix by formaldehyde solution.

Cardiac remodeling in patients with atrial fibrillation reversing bradycardia-induced cardiomyopathy: A case report

BACKGROUND

Bradycardia-induced cardiomyopathy (BIC), which is a disease resulting from bradycardia, is characterized by cardiac chamber enlargement and diminished cardiac function. The correction of bradycardia can allow for significant improvements in both cardiac function and structure; however, this disease has been infrequently documented. In this case, we conducted a longitudinal follow-up of a patient who had been enduring BIC for more than 40 years to heighten awareness and prompt timely diagnosis and rational intervention.

CASE SUMMARY

A woman who presented with postactivity fatigue and dyspnea was diagnosed with bradycardia at the age of 7. Since she had no obvious symptoms, she did not receive any treatment to improve her bradycardia during the 42-year follow-up, except for the implantation of a temporary pacemaker during labor induction surgery. As time progressed, the patient's heart gradually expanded due to her low ventricular rate, and she was diagnosed with BIC. In 2014, the patient developed atrial fibrillation, her ventricular rate gradually increased, and her heart shape gradually returned to normal. This report describes the cardiac morphological changes caused by the heart rate changes in BIC patients older than 40 years, introduces another possible outcome of BIC, and emphasizes the importance of early intervention in treating BIC.

CONCLUSION

BIC can induce atrial fibrillation, causing an increased ventricular rate and leading to positive cardiac remodeling.

Granulomatosis with polyangiitis induced by the anti-programmed cell death-1 inhibitor tislelizumab: A case report

BACKGROUND

Immune checkpoint inhibitors (ICIs) are a new class of antitumor agents. They enhance antitumor effects by blocking inhibitory receptors and related ligands expressed on T cells. ICIs also modulate regular immune cell activity, affecting the immune system and causing immune-related adverse events. The renal system is sometimes affected by these adverse events. Currently, the literature on ICIs-related glomerular injuries is scarce.

CASE SUMMARY

We present a patient who developed granulomatosis with polyangiitis (GPA) 3 weeks after treatment with the anti-programmed cell death-1 inhibitor, tislelizumab. The patient experienced proteinuria, hematuria, and acute kidney injury without pulmonary hemorrhage and tested positive for anti-neutrophil cytoplasmic antibody (ANCA)-cytoplasmic type. Renal biopsy confirmed ANCA-associated vasculitis, and GPA was finally diagnosed. The patient received pulse treatment with glucocorticoids and cyclophosphamide, and renal function improved. After self-discontinuation of the drug, the disease recurred, and the original treatment regimen was continued. However, the patient's renal function continued to deteriorate.

CONCLUSION

Glucocorticoids plus cyclophosphamide are effective for treating GPA induced by tislelizumab. However, follow-up and patient education are needed.

Extracorporeal membrane oxygenation combined with intra-aortic balloon counterpulsation for pheochromocytoma: A case report

BACKGROUND

Pheochromocytoma (PHEO) is a type of tumor that originates from chromaffin cells in the adrenal medulla and is classified as an adrenal paraganglioma. PHEOs can secrete catecholamines, leading to a variety of symptoms. Accurate diagnosis and appropriate treatment selection are crucial for favorable outcomes in these cases.

CASE SUMMARY

The patient presented with unexplained chest tightness, palpitations, and pink sputum. Upon examination and analysis of laboratory results, a diagnosis of adrenal PHEO was established. The PHEO secreted high levels of catecholamines, causing sudden fluctuations in blood pressure and heart rate, leading to extremely unstable hemodynamics. Treatment with extracorporeal membrane oxygenation and intra-aortic balloon counterpulsation helped stabilize the patient's vital signs, allowing for timely surgical intervention.

CONCLUSION

The combination of extracorporeal membrane oxygenation and intra-aortic balloon counterpulsation can enhance tissue perfusion, thus providing a solid foundation for the accurate diagnosis and effective surgical treatment of PHEO.

Diagnosis of poorly differentiated adenocarcinoma of the stomach by confocal laser endomicroscopy: A case report

BACKGROUND

In recent years, confocal laser endomicroscopy (CLE) has become a new endoscopic imaging technology at the microscopic level, which is extensively performed for real-time in vivo histological examination. CLE can be performed to distinguish benign from malignant lesions. In this study, we diagnosed using CLE an asymptomatic patient with poorly differentiated gastric adenocarcinoma.

CASE SUMMARY

A 63-year-old woman was diagnosed with gastric mucosal lesions, which may be gastric cancer, in the small curvature of the stomach by gastroscopy. She consented to undergo CLE for morphological observation of the gastric mucosa. Through the combination of CLE diagnosis and postoperative pathology, the intraoperative CLE diagnosis was considered to be reliable. According to our experience, CLE can be performed as the first choice for the diagnosis of gastric cancer.

CONCLUSION

CLE has several advantages over pathological diagnosis. We believe that CLE has great potential in the diagnosis of benign and malignant gastric lesions.

Diffuse large B cell lymphoma originating from the maxillary sinus with skin metastases: A case report and review of literature

BACKGROUND

Diffuse large B-cell lymphoma (DLBCL) is the most common type of malignant lymphoma (ML), accounting for 30%-40% of cases of non-Hodgkin's lymphoma (NHL) in adults. Primary paranasal sinus lymphoma is a rare presentation of extranodal NHL that accounts for only 0.17% of all lymphomas. ML from the maxillary sinus (MS) is a particularly rare presentation, and is thus often difficult to diagnose. We have reported the first known case of DLBCL originating from the MS with rapidly occurrent multiple skin metastasis.

CASE SUMMARY

An 81-year-old Japanese man visited our hospital due to continuous pain for 12 d in the left maxillary nerve area. His medical history included splenectomy due to a traffic injury, an old right cerebral infarction from when he was 74-years-old, hypertension, and type 2 diabetes mellitus. A plain head computed tomography (CT) scan revealed a 3 cm × 3.1 cm × 3 cm sized left MS. On day 25, left diplopia and ptosis occurred, and a follow-up CT on day 31 revealed the growth of the left MS mass. Based on an MS biopsy on day 50, we established a definitive diagnosis of DLBCL, non-germinal center B-cell-like originating from the left MS. The patient was admitted on day 62 due to rapid deterioration of his condition, and a plain CT scan revealed the further growth of the left MS mass, as well as multiple systemic metastasis, including of the skin. A skin biopsy on day 70 was found to be the same as that of the left MS mass. We notified the patient and his family of the disease, and they opted for palliative care, considering on his condition and age. The patient died on day 80.

CONCLUSION

This case suggests the need for careful, detailed examination, and for careful follow-up, when encountering patients presenting with a mass.

Mandibular left first premolar with three roots and three canals: A case report

BACKGROUND

The numbers of mandibular first premolar roots and root canals vary, and the incidence of three roots and three canals is 0.09%.

CASE SUMMARY

In this article, we review the root and root canal conditions for the mandibular first premolar and report the case of a mandibular left first premolar with three roots and three canals in a male patient, with suggestions for clinical diagnosis and treatment. The patient was referred by an orthodontist for the extraction of the tooth. Preoperative cone-beam computed tomography examination revealed that it had three roots. Under local anesthesia, the extraction socket was carefully expanded, and the tooth was successfully removed intact using forceps. The procedure was uneventful, with no root fractures, postoperative bleeding, or sensory abnormality observed.

CONCLUSION

The mandibular first premolar is characterized by multiple roots and canal variations that can increase the difficulty of treatment.

Removal of laparoscopic cerclage stitches via laparotomy and rivanol-induced labour: A case report and literature review

BACKGROUND

Laparoscopic cervical cerclage is performed for patients with abnormal cervical anatomy and/or transvaginal cervical cerclage failure. However, the method of removing the stitches to allow labour induction remains controversial. According to published literature, stitches are removed through laparoscopic or transvaginal methods. Herein, we report, for the first time, a case of a patient who had undergone laparoscopic cerclage, and then underwent removal of stitches by laparotomy and labour induction in the third trimester of pregnancy.

CASE SUMMARY

A patient who underwent laparoscopic cervical cerclage due to cervical insufficiency became pregnant naturally following the operation. At 31 wk of pregnancy, severe foetal malformations were found. To successfully induce labour, cerclage stitches were removed via laparotomy, and rivanol was injected directly into the uterus. Following successful induction of labour, the patient delivered a dead foetus.

CONCLUSION

This report provides a reliable scheme of removing cerclage stitches for patients who have undergone laparoscopic cerclage but experience severe foetal malformations.

Research progress on insomnia treated by traditional Chinese medicine and acupuncture based on microbial-gut-brain axis theory

Insomnia, as one of the emotional diseases, has been increasing in recent years, which has a great impact on people's life and work. Therefore, researchers are eager to find a more perfect treatment. The microbiome-gut-brain axis is a new theory that has gradually become popular abroad in recent years and has a profound impact in the field of insomnia. In recent years, traditional Chinese medicine (TCM) has played an increasingly important role in the treatment of insomnia, especially acupuncture and Chinese herbal medicine. It is the main method of TCM in the treatment of insomnia. This paper mainly reviews the combination degree of "microorganism-gut-brain axis" theory with TCM and acupuncture under the system of TCM. To explore the mechanism of TCM and acupuncture in the treatment of insomnia under the guidance of "microorganism-gut-brain axis" theory, in order to provide a new idea for the diagnosis and treatment of insomnia.

Ten-year multicentric retrospective analysis regarding postoperative complications and impact of comorbidities in hemorrhoidal surgery with literature review

BACKGROUND

Hemorrhoidal disease (HD) is considered a low-severity pathology by both general population and physicians, but the lengthy conservative therapy and postoperative complications suggest otherwise.

AIM

To assess the effectiveness of different treatment options, both conservative and surgical, in contrast with some preexisting comorbidities.

METHODS

We conducted a retrospective, 10-yearlong study between January 2011 and December 2021 in two surgical centers, a private and a state-owned hospital. We compared the efficacy and safety of several treatment options, such as open hemorrhoidectomy, stapled hemorrhoidopexy, rubber band ligation and infrared coagulation in terms of complication rates and types and their correlation with different preexisting comorbidities such as inflammatory bowel disease (IBD), use of anticoagulant medication (AM) and liver cirrhosis. We also conducted a 20-years long PubMed research (1.263 articles) for relevant comparisons.

RESULTS

Our study recorded 10940 patients with HD, 10241 with conservative and 699 with surgical treatment. Out of these, the male-to-female ratio of 1.3, and a peak in age distribution between 59 and 68 years old (32% of patients). For the entire study, we recorded a 90% incidence of immediate pain, immediate bleeding in 1.5% (11 cases), delayed bleeding in 1.0% (7 cases), and 0.6% surgical site infections. Urinary retention was also present, with 0.2% of patients, anal stricture in 1% and fecal incontinence for 0.5% of patients (4 cases). We recorded no severe complications such as Fournier`s gangrene or rectovaginal perforations. IBD accounted for 6% of the patients, with ulcerative colitis in 12% and Chron`s disease in 10.5%. 6.6% of the patients had AM, determining 4% immediate and 2% delayed bleeding, in surgically treated patients.

CONCLUSION

Our study determined that most common complications (pain, urinary retention, bleeding, and stricture) are correlated with each surgical technique and pre-existing comorbidities.

Evaluation of the clinical efficacy and safety of TST33 mega hemorrhoidectomy for severe prolapsed hemorrhoids

BACKGROUND

The pathogenesis of hemorrhoids is mainly anal cushion prolapse. Although the traditional treatment has a certain curative effect, it is not ideal. The remission rate of postoperative symptoms is low. Even if temporary remission is achieved, patients with hemorrhoids easily relapse after 1-2 years. The new technique of using staplers to treat prolapsed hemorrhoids has good therapeutic effects in clinical practice.

AIM

To explore the effect of TST33 mega stapler prolapse and hemorrhoid mucosal resection in the treatment of patients with severe prolapsed hemorrhoids.

METHODS

A total of 204 patients with severe prolapse hemorrhoids who were admitted to the department of anorectal in our hospital from April 2018 to June 2020 were selected, and the patients were randomly divided into group A and group B with 102 cases in each group using a randomized controlled clinical research program. Patients in Group A were treated with a TST33 mega stapler and hemorrhoid mucosal resection to treat prolapse, and patients in Group B were treated according to the Procedure for Prolapse and Hemorrhoids; the operation time, intraoperative blood loss, hospital stay, the difference in operation time, intraoperative blood loss, hospitalization time, pain degree before and after operation, degree of anal edema, anal Wexner score, and surgical complications were compared between the two groups of patients.

RESULTS

The operation time, intraoperative blood loss and hospitalization time in Group A were significantly lower than those in Group B (P < 0.05). The cure rate of Group A was 98.04%, compared with 95.10% cure rate of Group B, and the difference was not statistically significant (P > 0.05). The visual analogue scale (VAS) at 12 h and 24 h postoperatively in Group A were significantly lower than those in Group B (P < 0.05). The comparison of the VAS scores between Group A and Group B at 48 h, 72 h and 96 h postoperatively revealed that the difference was not statistically significant (P > 0.05). One day postoperatively, the degree of perianal edema in Group A was compared with that in Group B, and the difference was not statistically significant (P > 0.05). Seven days postoperatively, the degree of perianal edema in Group A was significantly lower than that in Group B (P < 0.05). The comparison of anal Wexner scores between the two groups preoperatively and at 1 mo, 3 mo and 6 mo postoperatively showed that the difference was not statistically significant (P > 0.05). The Wexner scores of the two groups at 1 mo, 3 mo and 6 mo postoperatively were significantly lower than the scores preoperatively (P < 0.05). The postoperative complication rate of Group A was 2.94% lower than that of Group B (11.76%), which was statistically significant (P < 0.05).

CONCLUSION

TST33 mega anastomotic hemorrhoidectomy treatment for patients with severe prolapse hemorrhoids, leads to less postoperative pain, the rapid recovery of perianal edema and has fewer complications.

Effect of three-volt moxibustion with helium-neon laser irradiation on quality of care in patients with lumbar radiculopathy spondylosis

BACKGROUND

Lumbar radiculopathy spondylosis is a relatively common orthopedic disease with a high incidence rate. It most commonly occurs in the lumbar 4-5 and lumbar 5-sacral 1 vertebrae, which account for approximately 95% of cases. It mostly occurs in people aged 30-50 years old and greatly affects their quality of life.

AIM

To determine the effect of triple-voltage acupuncture combined with helium-neon laser irradiation on the quality of care and improvement of symptoms in patients with lumbar radiculopathy spondylolisthesis.

METHODS

In this study, we selected 120 patients with lumbar radiculopathy spondylosis who were treated at our hospital between June 2019 to June 2020. The patients were divided into control and observation groups according to the random number table method, with 60 patients in each group. Patients in the observation group were treated with three-volt moxibustion combined with helium-neon laser irradiation, and those in the control group were treated with lumbar traction. After 1 month of treatment, the lumbar pain scores, lumbar spine motor functions, clinical treatment effects, and nursing satisfaction of the two groups were compared.

RESULTS

The results showed that acupuncture combined with laser irradiation significantly improved the patients' clinical symptoms, i.e., reduced their low back pain, significantly lower numerical rating scale pain scores in the observation group than in the control group, and better lumbar spine motility than in the control group, compared to lumbar traction. In addition, they were cared for. The treatment effectiveness rate of the observation group was 95.5%, which was significantly higher than that of the control group (81.67%). Satisfaction with care was higher than 90 points in both groups, but the difference was not statistically significant.

CONCLUSION

Our study provides a clinical rationale for the future treatment of patients with lumbar spine disease. However, further extensive research is needed for validation.

Self-management of osteoarthritis while waiting for total knee arthroplasty during the COVID-19 pandemic among older Malaysians

BACKGROUND

The study sought to understand the self-management strategies used by patients during the postponement of their total knee arthroplasty (TKA) procedure, as well as the associations between the length of waiting time, pain, and physical frailty and function. The study focused on individuals aged 50 years and above, as they are known to be more vulnerable to the negative impacts of delayed elective surgery and rehabilitation. This study hypothesizes that delayed TKR due to coronavirus disease 2019 (COVID-19) will bear negative effect in self-management, pain, and physical frailty and function in older adults.

AIM

To investigate the effects of COVID-19 pandemic on self-management, pain, and physical function in older adults awaiting TKA in Malaysia.

METHODS

This cross-sectional study has the data of participants, who matched the criteria and scheduled for TKA for the first time, extracted from the TKA registry in the Department of Orthopaedics and Traumatology, Hospital Canselor Tuanku Mukhriz. Data on pain status, and self-management, physical frailty, and instrumental activities daily living were also collected. Multiple linear regression analysis with a significant level of 0.05 was used to identify the association between waiting time and pain on physical frailty and functional performance.

RESULTS

Out of 180 had deferred TKA, 50% of them aged 50 years old and above, 80% were women with ethnic distribution Malay (66%), Chinese (22%), Indian (10%), and others (2%) respectively. Ninety-two percent of the participants took medication to manage their pain during the waiting time, while 10% used herbs and traditional supplements, and 68% did exercises as part of their osteoarthritis (OA) self-management. Thirty-six participants were found to have physical frailty (strength, assistance with walking, rising from a chair, climbing stairs, and falls questionnaire score > 4) which accounted for 72%. Increased pain was associated with physical frailty with odds ratio, odds ratio (95% confidence interval): 1.46 (1.04-2.05). This association remained significant even after the adjustment according to age and self-management.

CONCLUSION

While deferring TKA during a pandemic is unavoidable, patient monitoring for OA treatment during the waiting period is important in reducing physical frailty, ensuring the older patients' independence.

Ovarian growing teratoma syndrome with multiple metastases in the abdominal cavity and liver: A case report

BACKGROUND

Growing teratoma syndrome (GTS) is an unusual presentation of an amazing transformation of teratoma from malignant to benign on pathology during or after systemic or intraperitoneal chemotherapy. The definitive pathogenesis is still not fully understood due to the lack of large-sample studies.

CASE SUMMARY

A 53-year-old woman underwent radical surgery and postoperative intraperitoneal chemotherapy due to immature teratoma of the right ovary at the age of 28. She remained well during a 25-year follow-up period after surgery. Multiple asymptomatic solid masses were found in the liver on ultrasonography a month ago. Enhanced computed tomography (CT) of the abdomen revealed multiple masses in the abdominal cavity. The largest one was located in the posterior peritoneum next to the sixth segment of the right liver, about 7.9 cm × 7.5 cm in size. Three masses were present inside the liver, and one mass was in the right pelvic floor. Multiple lumps in the abdominal cavity were completely removed by surgery. During the operation, multiple space-occupying lesions were seen, ranging in size from 0.5 to 3 cm, and grayish white in color and hard in texture. Ovarian GTS was finally diagnosed based on postoperative pathology. After surgery, she recovered uneventfully. During a 3-year follow-up, the patient remained free of the disease without any recurrence on CT scan.

CONCLUSION

GTS is a rare phenomenon characterized by conversion of immature teratoma to mature one during or after chemotherapy and presents as growing and metastasizing masses. The pathogenesis of GTS is unclear, and the prognosis is good after surgical resection.

Intestinal microecology-based treatment for inflammatory bowel disease: Progress and prospects

Inflammatory bowel disease (IBD) is a chronic, recurrent, and debilitating disorder, and includes Crohn’s disease and ulcerative colitis. The pathogenesis of IBD is closely associated with intestinal dysbiosis, but has not yet been fully clarified. Genetic and environmental factors can influence IBD patients’ gut microbiota and metabolism, disrupt intestinal barriers, and trigger abnormal immune responses. Studies have reported the alteration of gut microbiota and metabolites in IBD, providing the basis for potential therapeutic options. Intestinal microbiota-based treatments such as pre/probiotics, metabolite supplementation, and fecal microbiota transplantation have been extensively studied, but their clinical efficacy remains controversial. Repairing the intestinal barrier and promoting mucosal healing have also been proposed. We here review the current clinical trials on intestinal microecology and discuss the prospect of research and practice in this field.

Review of risk factors, clinical manifestations, rapid diagnosis, and emergency treatment of neonatal perioperative pneumothorax

Perioperative neonatal pneumothorax (NP) is rare but very fatal. Most of the surgeries and treatments in the neonatal period are time-limited or emergent, and there are often some risk factors for pneumothorax before surgery. Physicians, surgeons and anesthesiologists need to identify possible risk factors for pneumothorax before surgery in preterm babies, patients receiving mechanical ventilation and those with underlying lung disease. The clinical presentation of NP is nonspecific, and patients may rapidly develop life-threatening complications if not promptly diagnosed and managed. This review highlights recent progress in the identification of risk factors, clinical manifestations, diagnosis and management of NP during the perioperative period.

Hypoperfusion context as a predictor of 28-d all-cause mortality in septic shock patients: A comparative observational study

BACKGROUND

As per the latest Surviving Sepsis Campaign guidelines, fluid resuscitation should be guided by repeated measurements of blood lactate levels until normalization. Nevertheless, raised lactate levels should be interpreted in the clinical context, as there may be other causes of elevated lactate levels. Thus, it may not be the best tool for real-time assessment of the effect of hemodynamic resuscitation, and exploring alternative resuscitation targets should be an essential research priority in sepsis.

AIM

To compare the 28-d mortality in two clinical patterns of septic shock: hyperlactatemic patients with hypoperfusion context and hyperlactatemic patients without hypoperfusion context.

METHODS

This prospective comparative observational study carried out on 135 adult patients with septic shock that met Sepsis-3 definitions compared patients with hyperlactatemia in a hypoperfusion context (Group 1, n = 95) and patients with hyperlactatemia in a non-hypoperfusion context (Group 2, n = 40). Hypoperfusion context was defined by a central venous saturation less than 70%, central venous-arterial PCO2 gradient [P(cv-a)CO2] ≥ 6 mmHg, and capillary refilling time (CRT) ≥ 4 s. The patients were observed for various macro and micro hemodynamic parameters at regular intervals of 0 h, 3 h, and 6 h. All-cause 28-d mortality and all other secondary objective parameters were observed at specified intervals. Nominal categorical data were compared using the χ2 or Fisher's exact test. Non-normally distributed continuous variables were compared using the Mann-Whitney U test. Receiver operating characteristic curve analysis with the Youden index determined the cutoff values of lactate, CRT, and metabolic perfusion parameters to predict the 28-d all-cause mortality. A P value of < 0.05 was considered significant.

RESULTS

Patient demographics, comorbidities, baseline laboratory, vital parameters, source of infection, baseline lactate levels, and lactate clearance at 3 h and 6 h, Sequential Organ Failure scores, need for invasive mechanical ventilation, days on mechanical ventilation, and renal replacement therapy-free days within 28 d, duration of intensive care unit stay, and hospital stay were comparable between the two groups. The stratification of patients into hypoperfusion and non-hypoperfusion context did not result in a significantly different 28-d mortality (24% vs 15%, respectively; P = 0.234). However, the patients within the hypoperfusion context with high P(cv-a)CO2 and CRT (P = 0.022) at baseline had significantly higher mortality than Group 2. The norepinephrine dose was higher in Group 1 but did not achieve statistical significance with a P > 0.05 at all measured intervals. Group 1 had a higher proportion of patients requiring vasopressin and the mean vasopressor-free days out of the total 28 d were lower in patients with hypoperfusion (18.88 ± 9.04 vs 21.08 ± 8.76; P = 0.011). The mean lactate levels and lactate clearance at 3 h and 6 h, CRT, P(cv-a)CO2 at 0 h, 3 h, and 6 h were found to be associated with 28-d mortality in patients with septic shock, with lactate levels at 6 h having the best predictive value (area under the curve lactate at 6 h: 0.845).

CONCLUSION

Septic shock patients fulfilling the hypoperfusion and non-hypoperfusion context exhibited similar 28-d all-cause hospital mortality, although patients with hypoperfusion displayed a more severe circulatory dysfunction. Lactate levels at 6 h had a better predictive value in predicting 28-d mortality than other parameters. Persistently high P(cv-a)CO2 (> 6 mmHg) or increased CRT (> 4 s) at 3 h and 6 h during early resuscitation can be a valuable additional aid for prognostication of septic shock patients.
