The ultrasound performed showed multiple right ovarian cystic ranging from 0.4 to 4 cm on the long axis. She underwent a right salpingo-oophorectomy in May 2022. The anatomical pathology result is in favor of a papillary carcinoma developed on stroma ovarii. No adjuvant treatment was necessary since the tumor was well limited, without capsular rupture, stage IA. The thyroid test was normal. The patient is currently being monitored. There is no sign of recurrence 20 months after surgery.展开更多

Unlike adult patients, children with thyroid nodules typically don’t complain of pain, soreness, or difficulty swallowing. Additionally, using the recommended therapy for adults to treat paediatrics is not appropriate. There is an unmet need for updated unique guidelines for the management of papillary thyroid carcinoma (PTC) in paediatrics and adolescents. Case Report: A 12-year-old girl had an atypical presentation of metastatic PTC in lymph nodes. She was treated initially with hemi-thyroidectomy, followed by total thyroidectomy. A multidisciplinary team followed her up till successful results were found. Conclusion: Due to the difference in pathophysiology between thyroid tumors in children and adults, a unique approach to PTC management is to be implemented. Further trials are required for a better understanding of risk factors, the likelihood of recurrence, and the long-term side effects of the chosen management plan.展开更多

The clinical char...Intravascular papillary endothelial hyperplasia is an unusual benign vascular lesion of the skin and subcutaneous tissue consisting of papillary formations lined with proliferative endothelial cells. The clinical characteristic is not specific and the diagnosis is based on histological examination. The lesion is often mistaken for angiosarcoma and a group of other benign and malignant vascular lesions. IPEH has been relatively rarely described in the head and neck region. An uncommon case located in the submandibular and sublingual region is presented which was misinterpreted as venous malformations and malignant tumors of vascular origin initially. A surgical excision was performed and no recurrences have been found after 5 years of follow-up.展开更多

Herein, we present a very rare case of benign concomitant retroperitoneal intramuscular hemangioma and intravascular papillary endothelial hyperplasia, with the unusual presentation of lumbosacral plexopathy. After surgical treatment and rehabilitation, the patient recovered uneventfully. This case report should serve to remind physicians of the rare condition of a retroperitoneal tumor leading to a neurological deficit.展开更多

Hence, this study aimed to investigate the regulation of BPH on gut microbiota composition and metabonomics.Methods: We analyzed gut samples from rats with BPH and healthy control rats, the gut microbiota composition and metabonomics were detected by 16S rDNA sequencing and liquid chromatography tandem mass spectrometry(LC–MS/MS).Results: High-throughput sequencing results showed that gut microbiota beta-diversity increased(P<0.01) in the BPH group vs. control group. Muribaculaceae(P<0.01), Turicibacteraceae(P<0.05), Turicibacter(P<0.01) and Coprococcus(P<0.01) were significantly decreased in the BPH group, whereas that of Mollicutes(P<0.05) and Prevotella(P<0.05)were significantly increased compared with the control group. Despite profound interindividual variability, the levels of several predominant genera were different. In addition, there were no statistically significant differences in several bacteria. BPH group vs. control group: Firmicutes(52.30% vs. 57.29%, P>0.05), Bacteroidetes(46.54% vs. 41.64%,P>0.05), Clostridia(50.89% vs. 54.66%, P>0.05), Ruminococcaceae(25.67% vs. 20.56%, P>0.05). LC–MS/MS of intestinal contents revealed that differential metabolites were mainly involved in cellular processes, environmental information processing, metabolism and organismal systems. The most important pathways were global and overview maps, lipid metabolism, amino acid metabolism, digestive system and endocrine system. Through enrichment analysis, we found that the differential metabolites were significantly enriched in metabolic pathways, steroid hormone biosynthesis,ovarian steroidogenesis, biosynthesis of unsaturated fatty acids and bile secretion. Pearson correlation analysis(R=0.94) showed that there was a strong correlation between Prevotellaceae, Corynebacteriaceae, Turicibacteraceae,Bifidobacteriaceae and differential metabolites.Conclusions: Our findings suggested an association between the gut microbiota and BPH, but the causal relationship between the two groups is unclear. Thus, further studies are warranted to elucidate the potential mechanisms and causal relationships between BPH and gut microbiota.展开更多

Gingival hyperplasia according to past reports has numerous etiological factors one of which is pregnancy due to increased hormone levels. Although pregnancy does not directly cause gingival hyperplasia, it may catalyze local etiological factors. Objectives: To determine the frequency and clinical aspects of gingival hyperplasia during pregnancy. Methodology: We conducted a cross sectional descriptive study from November 2021 to June 2022 at the Yaoundé Gyneco-Obstetrics and Pediatrics Hospital. Data were collected using a pretested questionnaire and clinical assessments done using dental consultation kits. Data were analyzed with the International Business Machine Statistical Package for Social Sciences (IBM SPSS) version 21.0 software. Results: We recruited 231 eligible participants for our study. Of 231, 101 (43.7%) had gingival hyperplasia. Most of our study population were between 20 - 40 years old and gingival hyperplasia was most commonly found in the 3<sup>rd</sup> trimester (60.7%). We reported that 31.3% of our population had a plaque score 2 and only 7.8% had consulted a dentist during pregnancy. We also observed that 93.3% of our population manifested a mild/moderate form of the disease while 6.9% had a severe form. Our study showed that 72.3% and 27.3% had a localized and generalized form of the disease, respectively. Conclusion: We concluded that gingival hyperplasia is a common pathology in pregnant women. It is most found in the third trimester. It presents more commonly as a localized form, and degree of severity is mostly moderate.展开更多

Methods: Retrospective a...Objective: Exploring the clinical efficacy of transurethral plasma enucleation of the prostate in the treatment of benign prostatic hyperplasia with underactive bladder detrusor contractility. Methods: Retrospective analysis of the clinical data of 68 patients with benign prostatic hyperplasia and underactive detrusor muscle contractility treated by our department from July 2021 to July 2022. The above patients all met the diagnosis of benign prostatic hyperplasia, excluding prostate cancer and urethral stricture. Urodynamics showed a decrease in the contractile force of the bladder detrusor muscle, and the surgical equipment used Olympus bipolar plasma resection equipment method. Divide the above patients into two groups: the experimental group of 34 patients who underwent transurethral plasma enucleation of the prostate and the control group of 34 patients who underwent transurethral plasma resection of the prostate. Evaluate the preoperative clinical baseline level and postoperative observation indicators of the two groups of patients, and compare the statistical differences between the two groups. Results: Both groups of patients successfully completed the surgery, and there were no serious complications such as rectal or bladder perforation during the surgery, with less bleeding. The postoperative QOL, IPSS, Qmax, and residual urine volume of patients undergoing transurethral plasma enucleation and resection of the prostate were significantly improved compared to those before surgery (P 0.05). Conclusion: Transurethral enucleation of the prostate has good efficacy and safety in the treatment of benign prostatic hyperplasia combined with weakened detrusor muscle contractility. Compared with traditional electric resection surgery, the efficacy is more significant. In terms of the main complications of the surgery, although there are slightly more patients with temporary urinary incontinence after prostate enucleation, there is no statistically significant difference compared to after electric resection, and they can recover to normal in the short term.展开更多

Malignant transformation may occur in rare cases. Papillary thyroid-type carcinoma represents the most common type of malignant struma ovarii, followed by follicular carcinoma. Malignant struma ovarii is commonly seen in women in the fifth decade. The diagnosis is often made post-operatively after histological examination. Histology also helps assess tumor aggressiveness (mitoses, necrosis, poorly differentiated subtype, etc.). Given the rarity of these lesions, no therapeutic consensus or prognostic value had yet been formally established. We report herein, the case of a 76-year-old woman with a cystic tumor of the right ovary and a nodular lesion of the bladder. The clinical symptomatology is nonspecific, associating abdomino-pelvic pain and a right latero-uterine mass on abdominal palpation. After total hysterectomy with bilateral adnexectomy, the diagnosis of papillary carcinoma arising from struma ovarii and extending into the bladder was made. Through this observation, we suggest to discuss the anatomoclinical particularities of this rare pathological entity.展开更多

The disease can be asymptomatic and discovered incidentally or symptomatic, which is often manifested by abdominal pain and motility disorders (diarrhea, constipation). The clinical presentation can also be alarming with rectal bleeding and obstructive symptoms that may be misinterpreted as a neoplastic process. In this paper, we report the case of a 58-year-old female patient with a previous history of appendicetomy. She presented with persistent abdominal pain, chronic constipation and black colored stools, following Covid-19 infection. The physical examination was unremarkable. Colonoscopy examination found a bulging, non-ulcerated mass, measuring 3.5 cm in greatest dimension, located at the right colic angle. Thoraco-abdomino-pelvic computed tomography was performed and showed right colonic wall thickening and enhanced nodule formation. Furthermore, metastatic localization was not detected. After a multidisciplinary meeting, a laparotomy with right hemicolectomy was performed. Histopathological examination of the surgical specimen revealed nodular lymphoid hyperplasia with CD20+, CD5−, CD10+ and BCL2−phenotype on immunohistochemistry. Besides, lymphocytes in interfollicular area are CD3+ T cells. Patient outcome was favorable after surgery and no additional treatment was necessary. Nodular lymphoid hyperplasia of the colon is a benign process whose endoscopic appearance can sometimes raise suspicion of malignancy. The diagnosis can only be established by histological evaluation. Immunohistochemistry is also essential to confirm the diagnosis and to rule out low-grade lymphoma. Clinical evolution is often favorable. However, endoscopic follow-up is necessary in all cases.展开更多
文摘A 64-year-old woman with no particular history presented with chronic pelvic pain since November 2021. The ultrasound performed showed multiple right ovarian cystic ranging from 0.4 to 4 cm on the long axis. She underwent a right salpingo-oophorectomy in May 2022. The anatomical pathology result is in favor of a papillary carcinoma developed on stroma ovarii. No adjuvant treatment was necessary since the tumor was well limited, without capsular rupture, stage IA. The thyroid test was normal. The patient is currently being monitored. There is no sign of recurrence 20 months after surgery.

文摘We evaluated the effect of isoquercetin(quercetin-O-3-glucoside-quercetin,IQ)as a functional component of Abeliophyllum disistichum Nakai ethanol extract(ADLE)on prostate cell proliferation and apoptosis and its effects on the IGF-1/PI3K/Akt/mTOR pathway in benign prostatic hyperplasia(BPH).Metabolites in ADLE were analyzed using UHPLC-qTOF-MS and HPLC.IQ was orally administered(1 or 10 mg/kg)to a testosterone propionate-induced BPH rat model,and its effects on the prostate weight were evaluated.The effect of IQ on androgen receptor(AR)signaling was analyzed in LNCaP cells.Whether IGF-1 and IQ affect the IGF-1/PI3K/Akt/mTOR pathway in BPH-1 cells was also examined.The metabolites in ADLE were identified and quantified,which confirmed that ADLE contained abundant IQ(20.88 mg/g).IQ significantly reduced the prostate size in a concentration-dependent manner in a BPH rat model,and significantly decreased the expression of AR signaling factors in the rat prostate tissue and LNCaP cells in a concentration-dependent manner.IQ also inhibited the PI3K/AKT/mTOR pathway activated by IGF-1 treatment in BPH-1 cells.In BPH-1 cells,IQ led to G0/G1 arrest and suppressed the expression of proliferation factors while inducing apoptosis.Thus,IQ shows potential for use as a pharmaceutical and nutraceutical for BPH.

文摘Background: Thyroid cancer is a rare disease yet the most common endocrine malignancy in pediatrics. Unlike adult patients, children with thyroid nodules typically don’t complain of pain, soreness, or difficulty swallowing. Additionally, using the recommended therapy for adults to treat paediatrics is not appropriate. There is an unmet need for updated unique guidelines for the management of papillary thyroid carcinoma (PTC) in paediatrics and adolescents. Case Report: A 12-year-old girl had an atypical presentation of metastatic PTC in lymph nodes. She was treated initially with hemi-thyroidectomy, followed by total thyroidectomy. A multidisciplinary team followed her up till successful results were found. Conclusion: Due to the difference in pathophysiology between thyroid tumors in children and adults, a unique approach to PTC management is to be implemented. Further trials are required for a better understanding of risk factors, the likelihood of recurrence, and the long-term side effects of the chosen management plan.

文摘BACKGROUND Intravascular papillary endothelial hyperplasia(IPEH)is a rare benign reactive vascular lesion that grows into an expansile compressing mass.It most commonly involves the skin and subcutaneous tissue.Spinal involvement is rare,with only 11 reported cases in the literature.We report,to our knowledge,the first case of IPEH in the cervicothoracic spinal canal and present a literature review.CASE SUMMARY A 27-year-old man presented with acute-onset neck pain,numbness,and weakness in his extremities.Magnetic resonance imaging showed an epidural mass in the cervicothoracic(C6-T1)spinal canal and vertebral hemangioma(VH)involving the C7 vertebral body.C6-T1 Laminectomy and radical excision of the mass were performed.Histopathological examinations revealed papillary proliferation of vascular endothelial cells with thrombus formation,and an IPEH diagnosis was made.By his 6-mo follow-up appointment,his symptoms were relieved without recurrence.The possible pathogenesis,clinical and imaging features,differential diagnosis,and management of IPEH were reviewed.CONCLUSION We report,to our knowledge,the first case of IPEH in the cervicothoracic spinal canal,treated via complete resection,and showing a favorable outcome.We found a causal relationship between spinal IPEH and VH;this partly explains the mechanism of IPEH.
文摘Intravascular papillary endothelial hyperplasia is an unusual benign vascular lesion of the skin and subcutaneous tissue consisting of papillary formations lined with proliferative endothelial cells. The clinical characteristic is not specific and the diagnosis is based on histological examination. The lesion is often mistaken for angiosarcoma and a group of other benign and malignant vascular lesions. IPEH has been relatively rarely described in the head and neck region. An uncommon case located in the submandibular and sublingual region is presented which was misinterpreted as venous malformations and malignant tumors of vascular origin initially. A surgical excision was performed and no recurrences have been found after 5 years of follow-up.
文摘Primary retroperitoneal tumors are rare, and benign retroperitoneal tumors are exceptionally rare. Herein, we present a very rare case of benign concomitant retroperitoneal intramuscular hemangioma and intravascular papillary endothelial hyperplasia, with the unusual presentation of lumbosacral plexopathy. After surgical treatment and rehabilitation, the patient recovered uneventfully. This case report should serve to remind physicians of the rare condition of a retroperitoneal tumor leading to a neurological deficit.

文摘BACKGROUND In recently diagnosed patients with thyroid cancer,papillary thyroid cancer(PTC),as the most common histological subtype,accounts for 90%of all cases.Although PTC is known as a relatively adolescent malignant disease,there still is a high possibility of recurrence in PTC patients with a poor prognosis.Therefore,new biomarkers are necessary to guide more effective stratification of PTC patients and personalize therapy to avoid overtreatment or inadequate treatment.Accumulating evidence demonstrates that microRNAs(miRNAs)have broad application prospects as diagnostic biomarkers in cancer.AIM To explore novel markers consisting of miRNA-associated signatures for PTC prognostication.METHODS We obtained and analyzed the data of 497 PTC patients from The Cancer Genome Atlas.The patients were randomly assigned to either a training or testing cohort.RESULTS We discovered 237 differentially expressed miRNAs in tumorous thyroid tissues compared with normal tissues,which contained 172 up-regulated and 65 downregulated miRNAs.The evaluation of differently expressed miRNAs was conducted using our risk score model.We then successfully generated a fourmiRNA potential prognostic signature[risk score=(-0.001×hsa-miR-181a-2-3p)+(0.003×hsa-miR-138-5p)+(-0.018×hsa-miR-424-3p)+(0.284×hsa-miR-612)],which reliably distinguished patients from high and low risk with a significant difference in the overall survival(P<0.01)and was effective in predicting the five-year disease survival rate with the area under the receiver operating characteristic curve of 0.937 and 0.812 in the training and testing cohorts,respectively.Additionally,there was a trend indicated that high-risk patients had shorter relapse-free survival,although statistical significance was not reached(P=0.082)in our sequencing cohort.CONCLUSION Our results indicated a four-miRNA signature that has a robust predictive effect on the prognosis of PTC.Accordingly,we would recommend more radical therapy and closer follow-ups for highrisk groups.

文摘BACKGROUND To date,endoscopic retrograde cholangiopancreatography has become a wellestablished treatment for common bile duct(CBD)stones.However,it is not suitable for some special patients,such as pregnant women,children or those who cannot stop taking anti-coagulation/anti-platelet agents because of radiation injury and the risk of postoperative bleeding resulting from endoscopic sphincterotomy.To overcome these two problems,this study introduced cholangioscopy-assisted extraction through a novel papillary support for small-calibre and sediment-like CBD stones.AIM To assess the feasibility and safety of cholangioscopy-assisted extraction through a novel papillary support(CEPTS)for small-calibre and sediment-like common bile duct(CBD)stones.METHODS This Retrospective study was approved by the Ethics Committee of the Chinese PLA General Hospital.We designed a covered single dumbbell-style papillary support between 2021 and 2022.Between July 2022 and September 2022,7 consecutive patients with small-calibre(cross diameter≤1.0 cm)or sediment-like CBD stones underwent CETPS procedures in our center.The clinical characteristics and treatment outcomes of these 7 patients were extracted from a prospectively collected database.And the related data were analyzed.Informed consent was obtained from all participating patients.RESULTS A total of 2 patients had yellow sediment-like CBD stones,and aspiration extraction was performed after the insertion of papillary support.Of the 5 patients with clumpy CBD stones(0.4-1.0 cm),2 underwent basket extraction under direct vision for a single stone(0.5-1.0 cm,black and black grey),1 underwent balloon plus aspiration extraction under direct vision for 5 stones(0.4-0.6 cm,brown),and 2 underwent aspiration extraction only for a single stone(0.5-0.6 cm,yellow,none).Technical success,namely,no residual stones in the CBD or left and right hepatic ducts,was achieved in all 7 cases(100%).The median operating time was 45.0 minutes(range 13.0–87.0 minutes).Postoperative pancreatitis(PEP)occurred in one case(14.3%).Hyperamylasaemia without abdominal pain was noted in 2 of 7 patients.No residual stones or cholangitis were found during the follow-up.CONCLUSION CETPS appeared to be feasible to treat patients with small-calibre or sediment-like CBD stones.Patients,especially pregnant women and those who cannot stop anticoagulation/anti-platelet agents,could benefit from this technique.

文摘Background: Studies had shown many diseases affect the stability of human microbiota, but how this relates to benign prostatic hyperplasia(BPH) has not been well understood. Hence, this study aimed to investigate the regulation of BPH on gut microbiota composition and metabonomics.Methods: We analyzed gut samples from rats with BPH and healthy control rats, the gut microbiota composition and metabonomics were detected by 16S rDNA sequencing and liquid chromatography tandem mass spectrometry(LC–MS/MS).Results: High-throughput sequencing results showed that gut microbiota beta-diversity increased(P<0.01) in the BPH group vs. control group. Muribaculaceae(P<0.01), Turicibacteraceae(P<0.05), Turicibacter(P<0.01) and Coprococcus(P<0.01) were significantly decreased in the BPH group, whereas that of Mollicutes(P<0.05) and Prevotella(P<0.05)were significantly increased compared with the control group. Despite profound interindividual variability, the levels of several predominant genera were different. In addition, there were no statistically significant differences in several bacteria. BPH group vs. control group: Firmicutes(52.30% vs. 57.29%, P>0.05), Bacteroidetes(46.54% vs. 41.64%,P>0.05), Clostridia(50.89% vs. 54.66%, P>0.05), Ruminococcaceae(25.67% vs. 20.56%, P>0.05). LC–MS/MS of intestinal contents revealed that differential metabolites were mainly involved in cellular processes, environmental information processing, metabolism and organismal systems. The most important pathways were global and overview maps, lipid metabolism, amino acid metabolism, digestive system and endocrine system. Through enrichment analysis, we found that the differential metabolites were significantly enriched in metabolic pathways, steroid hormone biosynthesis,ovarian steroidogenesis, biosynthesis of unsaturated fatty acids and bile secretion. Pearson correlation analysis(R=0.94) showed that there was a strong correlation between Prevotellaceae, Corynebacteriaceae, Turicibacteraceae,Bifidobacteriaceae and differential metabolites.Conclusions: Our findings suggested an association between the gut microbiota and BPH, but the causal relationship between the two groups is unclear. Thus, further studies are warranted to elucidate the potential mechanisms and causal relationships between BPH and gut microbiota.
文摘BACKGROUND Intraductal papillary neoplasm of the bile duct(IPNB)and intraductal papillary mucinous neoplasm(IPMN)of the pancreas have similar pathological manifestations.However,they often develop separately and it is rare for both to occur together.Patients presenting with heterochronic IPMN after IPNB are prone to be misdiagnosed with tumor recurrence.CASE SUMMARY A 67-year-old male patient was admitted 8.5 years after IPNB carcinoma and 4 years after the discovery of a pancreatic tumor.A left hepatic bile duct tumor with distal bile duct dilatation was found 8.5 years ago by the computed tomography;therefore,a left hepatectomy was performed.The postoperative pathological diagnosis was malignant IPNB with negative cutting edge and pathological stage T1N0M0.Magnetic resonance imaging 4 years ago showed cystic lesions in the pancreatic head with pancreatic duct dilatation,and carcinoembryonic antigen continued to increase.Positron emission tomography showed a maximum standard uptake value of 11.8 in the soft tissue mass in the pancreatic head,and a malignant tumor was considered.Radical pancreatoduodenectomy was performed.Postoperative pathological diagnosis was pancreatic head IPMN with negative cutting edge,pancreaticobiliary type,stage T3N0M0.He was discharged 15 d after the operation.Follow-up for 6 mo showed no tumor recurrence,and quality of life was good.CONCLUSION IPNB and IPMN are precancerous lesions with similar pathological characteristics and require active surgery and long-term follow-up.
文摘Thyroid cancer is the most common endocrine malignancy.While there has been no appreciable increase in the observed mortality of well-differentiated thyroid cancer,there has been an overall rise in its incidence worldwide over the last few decades.Patients with papillary thyroid carcinoma(PTC)and clinical evidence of central(cN1)and/or lateral lymph node metastases require total thyroidectomy plus central and/or lateral neck dissection as the initial surgical treatment.Nodal status in PTC patients plays a crucial role in the prognostic evaluation of the recurrence risk.The 2015 guidelines of the American Thyroid Association(ATA)have more accurately determined the indications for therapeutic central and lateral lymph node dissection.However,prophylactic central neck lymph node dissection(pCND)in negative lymph node(cN0)PTC patients is controversial,as the 2009 ATA guidelines recommended that CND“should be considered”routinely in patients who underwent total thyroidectomy for PTC.Although the current guidelines show clear indications for therapeutic CND,the role of pCND in cN0 patients with PTC is still debated.In small solitary papillary carcinoma(T1,T2),pCND is not recommended unless there are high-risk prediction factors for recurrence and diffuse nodal spread(extrathyroid extension,mutation in the BRAF gene).pCND can be considered in cN0 disease with advanced primary tumors(T3 or T4)or clinical lateral neck disease(cN1b)or for staging and treatment planning purposes.The role of the preoperative evaluation is fundamental to minimizing the possible detrimental effect of overtreatment of the types of patients who are associated with low disease-related morbidity and mortality.On the other hand,it determines the choice of appropriate treatment and determines if close monitoring of patients at a higher risk is needed.Thus,pCND is currently recommended for T3 and T4 tumors but not for T1 and T2 tumors without high-risk prediction factors of recurrence.

文摘BACKGROUND Intraductal papillary neoplasm of the bile duct(IPNB)is a rare distinct subtype of precursor lesions of biliary carcinoma.IPNB is considered to originate from luminal biliary epithelial cells,typically displays mucin-hypersecretion or a papillary growth pattern,and results in cystic dilatation[1].IPNB develops anywhere in the intrahepatic and extrahepatic biliary tracts,and can occur in various pathological stages from low-grade dysplasia to invasive carcinoma.IPNBs have similar phenotypic changes in the occurrence and development of all subtypes,and the prognosis is significantly better than that of traditional(nonpapillary)cholangiocarcinoma.AIM To evaluate the clinicopathological features of IPNB to provide evidence-based guidance for treatment.METHODS Invasive IPNB,invasive intraductal papillary mucinous neoplasm of the pancreas(IPMN),and traditional cholangiocarcinoma data for affected individuals from 1975 to 2016 were obtained from the Surveillance,Epidemiology,and End Results(SEER)database.Annual percentage changes(APCs)in the incidence and incidence-based(IB)mortality were calculated.We identified the independent predictors of overall survival(OS)and cancer-specific survival(CSS)in indivi duals with invasive IPNB.RESULTS The incidence and IB mortality of invasive IPNB showed sustained decreases,with an APC of-4.5%(95%CI:-5.1%to-3.8%)and-3.3%(95%CI:-4.1%to-2.6%)(P<0.001),respectively.Similar decreases in incidence and IB mortality were seen for invasive IPMN but not for traditional cholangiocarcinoma.Both OS and CSS for invasive IPNB were better than for invasive IPMN and traditional cholangiocarcinoma.A total of 1635 individuals with invasive IPNB were included in our prognosis analysis.The most common tumor sites were the pancreaticobiliary ampulla(47.9%)and perihilar tract(36.7%),but the mucin-related subtype of invasive IPNB was the main type,intrahepatically(approximately 90%).In the univariate and multivariate Cox regression analysis,age,tumor site,grade and stage,subtype,surgery,and chemotherapy were associated with OS and CSS(P<0.05).CONCLUSION Incidence and IB mortality of invasive IPNB trended steadily downward.The heterogeneity of IPNB comprises site and the tumor’s mucin-producing status.
文摘Gingival hyperplasia or gingival overgrowth, which is a common trait of gingival disease, is characterized by an increase in the size of the gingiva. Gingival hyperplasia according to past reports has numerous etiological factors one of which is pregnancy due to increased hormone levels. Although pregnancy does not directly cause gingival hyperplasia, it may catalyze local etiological factors. Objectives: To determine the frequency and clinical aspects of gingival hyperplasia during pregnancy. Methodology: We conducted a cross sectional descriptive study from November 2021 to June 2022 at the Yaoundé Gyneco-Obstetrics and Pediatrics Hospital. Data were collected using a pretested questionnaire and clinical assessments done using dental consultation kits. Data were analyzed with the International Business Machine Statistical Package for Social Sciences (IBM SPSS) version 21.0 software. Results: We recruited 231 eligible participants for our study. Of 231, 101 (43.7%) had gingival hyperplasia. Most of our study population were between 20 - 40 years old and gingival hyperplasia was most commonly found in the 3<sup>rd</sup> trimester (60.7%). We reported that 31.3% of our population had a plaque score 2 and only 7.8% had consulted a dentist during pregnancy. We also observed that 93.3% of our population manifested a mild/moderate form of the disease while 6.9% had a severe form. Our study showed that 72.3% and 27.3% had a localized and generalized form of the disease, respectively. Conclusion: We concluded that gingival hyperplasia is a common pathology in pregnant women. It is most found in the third trimester. It presents more commonly as a localized form, and degree of severity is mostly moderate.

文摘Background:Limited endoscopic sphincterotomy with large balloon dilation(ES-LBD)and endoscopic papillary large-balloon dilation(EPLBD)have been proven safe and effective for removal of bile duct stones.However,the long-term outcomes are not clear.The aim of this study was to assess the long-term outcomes of EPLBD(12-15 mm)with or without limited sphincterotomy for removal of common bile duct(CBD)stones.Methods:Patients with EPLBD or ES-LBD referred for the removal of bile-duct stones between June 2008 and August 2020 were retrospectively reviewed.Complete stone clearance,endoscopic retrograde cholangiopancreatography(ERCP)-related adverse events,and late biliary complications during long-term follow-up were analyzed.Results:Basic patient characteristics were not significantly different between the groups that underwent EPLBD(n=168)and ES-LBD(n=57).EPLBD compared with ES-LBD resulted in similar outcomes in terms of overall successful stone removal(99.4%vs.100%,P=1.00)and ERCP-related adverse events(7.7%vs.5.3%,P=0.77).The mean duration of the follow-up were 113.6 months and 106.7 months for patients with EPLBD and ES-LBD,respectively(P=0.13).There was no significant difference between EPLBD and ES-LBD in the incidence of stone recurrence[20(11.9%)vs.9(15.8%);P=0.49].Multivariate analysis showed that a diameter of CBD≥15 mm(OR=3.001;95%CI:1.357-6.640;P=0.007)was an independent risk factor for stone recurrence.Conclusions:The application of a large balloon(12-15 mm)via EPLBD is an effective and safe alternative to ES-LBD for extraction of large CBD stones.Endoscopic sphincterotomy prior to EPLBD may be unnec-essary.A diameter of CBD≥15 mm is a risk factor of stone recurrence.
文摘Objective: Exploring the clinical efficacy of transurethral plasma enucleation of the prostate in the treatment of benign prostatic hyperplasia with underactive bladder detrusor contractility. Methods: Retrospective analysis of the clinical data of 68 patients with benign prostatic hyperplasia and underactive detrusor muscle contractility treated by our department from July 2021 to July 2022. The above patients all met the diagnosis of benign prostatic hyperplasia, excluding prostate cancer and urethral stricture. Urodynamics showed a decrease in the contractile force of the bladder detrusor muscle, and the surgical equipment used Olympus bipolar plasma resection equipment method. Divide the above patients into two groups: the experimental group of 34 patients who underwent transurethral plasma enucleation of the prostate and the control group of 34 patients who underwent transurethral plasma resection of the prostate. Evaluate the preoperative clinical baseline level and postoperative observation indicators of the two groups of patients, and compare the statistical differences between the two groups. Results: Both groups of patients successfully completed the surgery, and there were no serious complications such as rectal or bladder perforation during the surgery, with less bleeding. The postoperative QOL, IPSS, Qmax, and residual urine volume of patients undergoing transurethral plasma enucleation and resection of the prostate were significantly improved compared to those before surgery (P 0.05). Conclusion: Transurethral enucleation of the prostate has good efficacy and safety in the treatment of benign prostatic hyperplasia combined with weakened detrusor muscle contractility. Compared with traditional electric resection surgery, the efficacy is more significant. In terms of the main complications of the surgery, although there are slightly more patients with temporary urinary incontinence after prostate enucleation, there is no statistically significant difference compared to after electric resection, and they can recover to normal in the short term.
文摘Ovarian goiter is a form of single tissue teratoma of the ovary, accounting for 2% - 3% of mature ovarian teratomas. Malignant transformation may occur in rare cases. Papillary thyroid-type carcinoma represents the most common type of malignant struma ovarii, followed by follicular carcinoma. Malignant struma ovarii is commonly seen in women in the fifth decade. The diagnosis is often made post-operatively after histological examination. Histology also helps assess tumor aggressiveness (mitoses, necrosis, poorly differentiated subtype, etc.). Given the rarity of these lesions, no therapeutic consensus or prognostic value had yet been formally established. We report herein, the case of a 76-year-old woman with a cystic tumor of the right ovary and a nodular lesion of the bladder. The clinical symptomatology is nonspecific, associating abdomino-pelvic pain and a right latero-uterine mass on abdominal palpation. After total hysterectomy with bilateral adnexectomy, the diagnosis of papillary carcinoma arising from struma ovarii and extending into the bladder was made. Through this observation, we suggest to discuss the anatomoclinical particularities of this rare pathological entity.
文摘Nodular lymphoid hyperplasia of the colon (NLHC) is an uncommon pathology in adults. The disease can be asymptomatic and discovered incidentally or symptomatic, which is often manifested by abdominal pain and motility disorders (diarrhea, constipation). The clinical presentation can also be alarming with rectal bleeding and obstructive symptoms that may be misinterpreted as a neoplastic process. In this paper, we report the case of a 58-year-old female patient with a previous history of appendicetomy. She presented with persistent abdominal pain, chronic constipation and black colored stools, following Covid-19 infection. The physical examination was unremarkable. Colonoscopy examination found a bulging, non-ulcerated mass, measuring 3.5 cm in greatest dimension, located at the right colic angle. Thoraco-abdomino-pelvic computed tomography was performed and showed right colonic wall thickening and enhanced nodule formation. Furthermore, metastatic localization was not detected. After a multidisciplinary meeting, a laparotomy with right hemicolectomy was performed. Histopathological examination of the surgical specimen revealed nodular lymphoid hyperplasia with CD20+, CD5−, CD10+ and BCL2−phenotype on immunohistochemistry. Besides, lymphocytes in interfollicular area are CD3+ T cells. Patient outcome was favorable after surgery and no additional treatment was necessary. Nodular lymphoid hyperplasia of the colon is a benign process whose endoscopic appearance can sometimes raise suspicion of malignancy. The diagnosis can only be established by histological evaluation. Immunohistochemistry is also essential to confirm the diagnosis and to rule out low-grade lymphoma. Clinical evolution is often favorable. However, endoscopic follow-up is necessary in all cases.
