Very few studies exist regarding these aspects in our setting, and they are mostly outdated. This study aimed to describe the diagnostic aspects, current surgical treatment with technical improvements, and progression in patients. Patients and Methods: We conducted a multicentre retrospective descriptive study over a 10-year period between January 2011 and January 2020 in three referral centres in Yaoundé. All patients who underwent surgery for cervical myelopathy were included. Results: Fifty-two patients were recruited. The rate of operated cervical myelopathies among all degenerative spinal pathologies was 14.05%. The M/F sex ratio was 3/1, and the average age was 52 ± 10 years. All included patients had gait problems, 90.38% demonstrated motor deficiency, and 67.30% experienced at least three levels of compression. Surgery was decided based on the Nurick grade;a posterior approach was applied to 86.54% of patients. Postoperative progression showed a neurological improvement of 82% with an average follow-up of 4 years. Conclusion: In this study, the patients who underwent surgery were relatively young, their clinical presentations were mostly advanced, and surgical management showed good results in well-selected cases.展开更多

Cervicosteoarthritis is the main etiology. The purpose of this work was to identify clinical factors that may influence neurological recovery in patients undergoing surgery for cervical myelopathy in our work setting. Materials and Methods: We performed a retrospective analytical study on patients operated on for cervical myelopathy at the teaching hospital of Bouake. The logistic regression model was used to identify the factors influencing post-operative neurological recovery. Results: 50 patients’ records have been enrolled in this study. The mean age of our patients was 53 years with extremes ranging from 25 to 78 years and 39 of our patients (62%) were male. The mean modified pre-operative JOA score was 11.62 versus 12.94 after the surgery. Age, sex, the number of levels operated on and the duration of the evolution of the signs showed no significant link with neurological recovery. Preoperative mild myelopathy (P = 0.0491) and post-operative functional rehabilitation (P = 0.0459) were identified as factors favouring neurological recovery after cervical myelopathy surgery. Conclusion: The good conducts of functional rehabilitation sessions as well as a mild myelopathy were the factors favouring neurological recovery.展开更多

It is traditionally classified by cervical spinal cord and/or nerve root compression which varies in severity and number of levels involved. The vast array of clinical manifestations of cervical myelopathy cannot fully be explained by the simple concept that a narrowed spinal canal causes compression of the cord, local tissue ischemia, injury and neurological impairment. Despite advances in surgical technology and treatment innovations, there are limited neuro-protective treatments for cervical myelopathy, which reflects an incomplete understanding of the pathophysiological processes involved in this disease. The aim of this review is to provide a comprehensive overview of the key pathophysiological processes at play in the development of cervical myelopathy.展开更多

We have developed a unique modification of the surgical procedure to keep the lamina expanded, with the aim of preventing reclosure of the vertebral arch. To examine the effectiveness of and problems associated with the modified expansive open-door laminoplasty technique developed at our institution by evaluating the surgical outcomes. Methods and Materials: Fifty-six patients (46 men and 10 women) underwent the modified expansive open-door laminoplasty and were followed up for at least 1 year. Thirty-eight had Cervical Spondylotic Myelopathy (CSM) and 18 had OPLL. The patients were 34 to 89 years of age (mean: 60.9 years). The severity of myelopathy was evaluated according to the Japanese Orthopaedic Association’s scoring system. Surgical outcomes were evaluated using Hirabayashi’s system for determining recovery rate. In the radiographic analysis, the following angles were measured before and after surgery: lordosis angle and Range of Motion (ROM) at C2 - C7 on lateral radiographs, and opening angle on computerized tomography (CT). The presence and absence of axial pain and postoperative C5 palsy were also evaluated. Results: The rate of JOA score improvement was about 60%, the lordosis angle observed on lateral radiographs was maintained. ROM decreased after surgery in both the CSM and OPLL groups, and the extent of the decrease was similar to that in previous reports. The opening angle of the lamina was 62°- 65° on post-operative CT. Axial pain was reported by 34% of patients. Conclusions: Our modified procedure produced satisfactory postoperative outcomes based on the clinical data and imaging findings for both CSM and OPLL. The advantage of this procedure is that it avoids potential complications associated with bone grafts or implants.展开更多

Degenerative cervical spondylosis, osteophytes, discosteophyte complex, degenerative spondylolisthesis and hypertrophy of ligamentum flavum are the main etiologies of cervical myelopathy. Metastasis to cervical spine could be a rare cause of cervical myelopathy. The present study is a case report;presented a 36-year-old male with severe pain in cervical region, gait disability and impairment in sensory and motor function of upper left extremity. The patient had a history of thyroidectomy and cervical lymph node dissection due to follicular thyroid carcinoma (FTC) with improper follow-ups. He was diagnosed with metastatic cervical myelopathy and underwent surgical treatment. Cervical myelopathy due to metastasis is a rare condition and only few cases have been reported so far. So myelopathies can be a complication of metastatic cancers, and it should be considered by health professionals.展开更多

This study intended to analyze the pregnancy outcomes following cervical treatment in Cameroon. Methods: This was a cohort study with two years retrospective data collection involving 82 women who underwent cervical treatment for CIN in two Cameroonian hospitals from January 2015 to December 2017. Data were collected from CIN treatment to end of pregnancy where applicable. Data analysis was done using Epi Info software version 3.5.4. Results: We collected data from 82 patients aged 27 to 48 years, with a mean age of 36.5 (SD: 5.3) years. During the study period, 33 out of 82 participants became pregnant 40.2 [29.56 - 51.66]%. The factor associated with pregnancy occurrence after treatment was age less than 35 years (Odds ratio = 4.37 [1.7 - 11.2]. From the 33 pregnancies recorded, 17 (51.5%) ended in a delivery, amongst which 15 (88.2%) were vaginal. Conclusion: Pregnancy frequency over two years following cervical treatment for CIN was relatively good, and younger women (age 35 years) were significantly more like to have conceived compared to their older counterparts. Post-treatment delivery outcomes seem to be similar to those in the general population.展开更多

Surgery is the primary treatment modality when the disease is diagnosed at early stage. Radical hysterectomy in cervical cancer has not been evaluated in recent years in Cameroon. The purpose of this study is thus to evaluate the epidemiological and clinical features and short term outcomes of patients who underwent surgery. Patients and methods: This retrospective study was conducted at the Douala Gynaeco-obstetric and Pediatric Hospital and the Douala General Hospital. Cervical cancer patients who underwent Radical hysterectomy between January 2015 and December 2020 were included. A pre-established data collection tool was used to record socio-demographic, clinical and outcomes information from patients’ files;additional outcome information was obtained from phone calls. Descriptive analysis was done using the SPSS version 26. Bivariate analysis was used to determine associations between disease and patients characteristics and occurrence of adverse postoperative outcome. P value of 0.05 was considered. Results: Sixty one patients were enrolled. Their ages ranged from 33 to 74 years with a mean age of 51.95 ± 10.29 years. Over 85% of women were married, 65.57% were unemployed and 86.88% were multiparous. Only 28% had never done cervical cancer screening. Most patients had stage IB1 to IB2 stage disease (57.1%). Less than 9% underwent radical hysterectomy and 8 of those (13.11%) suffered intraoperative complications. Twenty-five patients (40.98%) presented immediate and short term complications. There was no significant association between the disease or patients’ characteristics and adverse outcomes. Conclusion: Cervical cancer patients are relatively young in our settings and only 9% of them reach the hospital at early stage. Postoperative adverse outcomes rate is higher than that reported in the literature. Sensitization on screening and awareness of early symptoms can reverse the situation.展开更多

Majority of the recipients of these treatments are women within the reproductive age group, who according to literature may be at risk of adverse pregnancy outcomes. This pilot study is part of a study investigating adverse pregnancy outcomes among women who received Cryotherapy, Thermal ablation and Loop Electrosurgical Excision Procedure compared to the untreated women in Zambia. Materials and Methods: This descriptive study analyzed records of 886 (n = 443 treated and n = 443 untreated) women aged 15 - 49 years. The women were either screened with Visual Inspection with Acetic Acid or treated for Cervical Intraepithelial neoplasia at the Adult Infectious Disease Centre between January 2010 and December 2020. Women meeting the criteria were identified using the Visual Inspection with Acetic Acid screening records and telephone interviews to obtain the adverse pregnancy outcome experienced. Data were analysed using STATA version 16 to determine the prevalence and obtain frequency distribution of outcomes of interest. Univariate and multivariable binary logistic regression estimated odds of adverse pregnancy outcomes across the three treatments. Results: The respondents were aged 15 to 49 years. Adverse pregnancy outcomes were observed to be more prevalent in the treatment group (18.5%) compared to the untreated group (5.4%). Normal pregnancy outcomes were lower in the treated (46.3%;n = 443) than the untreated (53.7%;n = 443). The treated group accounted for the majority of abortions (85.2%), prolonged labour (85.7%) and low birth weight (80%), whereas, the untreated accounted for the majority of still births (72.7%). Women treated with cryotherapy (aOR = 2.43, 95% CI = 1.32 - 4.49, p = 0.004), thermal ablation (aOR = 6.37, 95% CI = 0.99 - 41.2, p = 0.052) and Loop Electrosurgical Excision Procedure (aOR = 9.67, 95% CI = 2.17 - 43.1, p = 0.003) had two-, six- and ten-times higher odds of adverse pregnancy outcomes respectively, relative to women who required no treatment. Conclusion: Adverse pregnancy outcomes are prevalent among women who have received treatment in Zambia. The findings indicate that treating Cervical Intraepithelial Neoplasia has been linked to higher chances of experiencing abortion, delivering low birth weight babies and enduring prolonged labor that may result in a caesarean section delivery. Cervical neoplasia treatments, particularly Loop Electrosurgical Excision Procedure, are associated with significantly increased odds of adverse pregnancy outcomes. It is essential to include information about prior Cervical Intraepithelial neoplasia treatment outcomes in obstetric care.展开更多

They are not accompanied by neurological deficit in childhood but attached cord syndrome can occur with growth. Surgical treatment, in addition to avoiding rupture and correcting the aesthetic damage, will preserve neurological functions. We report 2 cases that we took care of. They are a 5-month-old infant and a 3-year-old girl. The first presented a 7 cm rounded meningocele pedunculated through the C1 lamina defect. The second presented an 8.6 cm polylobed meningocele pedunculated through the C2 lamina defect. They both underwent surgery with good progress.展开更多

The T2 signal change on conventional magnetic resonance imaging(MRI) is most commonly associated with neurological deficits. Diffusion tensor imaging and MR spectroscopy show altered microstructure and biochemistry that reflect patient-specific pathogenesis and can be used to predict neurological outcome and response to intervention. Functional MRI can help to assess the neurological functional recovery after decompression surgery for CSM.展开更多
文摘Introduction: Although cervical myelopathy is the most common degenerative cervical spine pathology in adults, the indications and approaches of surgical treatment have not yet been clearly defined in the literature. Very few studies exist regarding these aspects in our setting, and they are mostly outdated. This study aimed to describe the diagnostic aspects, current surgical treatment with technical improvements, and progression in patients. Patients and Methods: We conducted a multicentre retrospective descriptive study over a 10-year period between January 2011 and January 2020 in three referral centres in Yaoundé. All patients who underwent surgery for cervical myelopathy were included. Results: Fifty-two patients were recruited. The rate of operated cervical myelopathies among all degenerative spinal pathologies was 14.05%. The M/F sex ratio was 3/1, and the average age was 52 ± 10 years. All included patients had gait problems, 90.38% demonstrated motor deficiency, and 67.30% experienced at least three levels of compression. Surgery was decided based on the Nurick grade;a posterior approach was applied to 86.54% of patients. Postoperative progression showed a neurological improvement of 82% with an average follow-up of 4 years. Conclusion: In this study, the patients who underwent surgery were relatively young, their clinical presentations were mostly advanced, and surgical management showed good results in well-selected cases.
文摘Introduction: Cervical myelopathy is the most common myelopathy among people over 50 of age. Cervicosteoarthritis is the main etiology. The purpose of this work was to identify clinical factors that may influence neurological recovery in patients undergoing surgery for cervical myelopathy in our work setting. Materials and Methods: We performed a retrospective analytical study on patients operated on for cervical myelopathy at the teaching hospital of Bouake. The logistic regression model was used to identify the factors influencing post-operative neurological recovery. Results: 50 patients’ records have been enrolled in this study. The mean age of our patients was 53 years with extremes ranging from 25 to 78 years and 39 of our patients (62%) were male. The mean modified pre-operative JOA score was 11.62 versus 12.94 after the surgery. Age, sex, the number of levels operated on and the duration of the evolution of the signs showed no significant link with neurological recovery. Preoperative mild myelopathy (P = 0.0491) and post-operative functional rehabilitation (P = 0.0459) were identified as factors favouring neurological recovery after cervical myelopathy surgery. Conclusion: The good conducts of functional rehabilitation sessions as well as a mild myelopathy were the factors favouring neurological recovery.

文摘Objectives: Expansive open-door laminoplasty is used widely for the treatment of cervical spondylosis and Ossification of the Posterior Longitudinal Ligament (OPLL). We have developed a unique modification of the surgical procedure to keep the lamina expanded, with the aim of preventing reclosure of the vertebral arch. To examine the effectiveness of and problems associated with the modified expansive open-door laminoplasty technique developed at our institution by evaluating the surgical outcomes. Methods and Materials: Fifty-six patients (46 men and 10 women) underwent the modified expansive open-door laminoplasty and were followed up for at least 1 year. Thirty-eight had Cervical Spondylotic Myelopathy (CSM) and 18 had OPLL. The patients were 34 to 89 years of age (mean: 60.9 years). The severity of myelopathy was evaluated according to the Japanese Orthopaedic Association’s scoring system. Surgical outcomes were evaluated using Hirabayashi’s system for determining recovery rate. In the radiographic analysis, the following angles were measured before and after surgery: lordosis angle and Range of Motion (ROM) at C2 - C7 on lateral radiographs, and opening angle on computerized tomography (CT). The presence and absence of axial pain and postoperative C5 palsy were also evaluated. Results: The rate of JOA score improvement was about 60%, the lordosis angle observed on lateral radiographs was maintained. ROM decreased after surgery in both the CSM and OPLL groups, and the extent of the decrease was similar to that in previous reports. The opening angle of the lamina was 62°- 65° on post-operative CT. Axial pain was reported by 34% of patients. Conclusions: Our modified procedure produced satisfactory postoperative outcomes based on the clinical data and imaging findings for both CSM and OPLL. The advantage of this procedure is that it avoids potential complications associated with bone grafts or implants.

文摘BACKGROUND Cervical myelopathy is a potential stroke imitator,for which intravenous thrombolysis would be catastrophic.CASE SUMMARY We herein present two cases of cervical myelopathy.The first patient presented with acute onset of right hemiparesis and urinary incontinence,and the second patient presented with sudden-onset right leg monoplegia.The initial diagnoses for both of them were ischemic stroke.However,both of them lacked cranial nerve symptom and suffered neck pain at the beginning of onset.Their cervical spinal cord lesions were finally confirmed by cervical computed tomography.A literature review showed that neck pain and absence of cranial nerve symptom are clues of cervical myelopathy.CONCLUSION The current report and the review remind us to pay more attention to these two clues in suspected stroke patients,especially those within the thrombolytic time window.
文摘Cervical myelopathy is a consequence of spinal cord compression in the cervical spine. Degenerative cervical spondylosis, osteophytes, discosteophyte complex, degenerative spondylolisthesis and hypertrophy of ligamentum flavum are the main etiologies of cervical myelopathy. Metastasis to cervical spine could be a rare cause of cervical myelopathy. The present study is a case report;presented a 36-year-old male with severe pain in cervical region, gait disability and impairment in sensory and motor function of upper left extremity. The patient had a history of thyroidectomy and cervical lymph node dissection due to follicular thyroid carcinoma (FTC) with improper follow-ups. He was diagnosed with metastatic cervical myelopathy and underwent surgical treatment. Cervical myelopathy due to metastasis is a rare condition and only few cases have been reported so far. So myelopathies can be a complication of metastatic cancers, and it should be considered by health professionals.

文摘Efforts to promote recovery of function after human spinal cord injury(SCI) will likely require interventions to rgeting the corticospinal tract(CST) motor system:the most important pathway for voluntary motor control in humans.This system has historically been the most refractory to regenerative efforts after SCI.The "nonregeneration" of the CST changed when robust regeneration of the CST into spared tissue was demonstrated by the inactivation of phosphatase and tensin homolog and delivery of inosine.

文摘Cervical cancer(CC) epidemiology CC, the fourth most frequently diagnosed malignancy in women worldwide, is a major global health challenge, particularly in low-resource regions. Approximately 88.1% of the 604,000 CC new cases occurred in low-and middle-income countries in 2020, and more than 90% of the 342,000 CC deaths occurred in low-and middle-income countries in 2020~1.
文摘Objective: In Cameroon, more than 80% of women suffering from cervical intraepithelial neoplasia (CIN) are within the reproductive age. This study intended to analyze the pregnancy outcomes following cervical treatment in Cameroon. Methods: This was a cohort study with two years retrospective data collection involving 82 women who underwent cervical treatment for CIN in two Cameroonian hospitals from January 2015 to December 2017. Data were collected from CIN treatment to end of pregnancy where applicable. Data analysis was done using Epi Info software version 3.5.4. Results: We collected data from 82 patients aged 27 to 48 years, with a mean age of 36.5 (SD: 5.3) years. During the study period, 33 out of 82 participants became pregnant 40.2 [29.56 - 51.66]%. The factor associated with pregnancy occurrence after treatment was age less than 35 years (Odds ratio = 4.37 [1.7 - 11.2]. From the 33 pregnancies recorded, 17 (51.5%) ended in a delivery, amongst which 15 (88.2%) were vaginal. Conclusion: Pregnancy frequency over two years following cervical treatment for CIN was relatively good, and younger women (age 35 years) were significantly more like to have conceived compared to their older counterparts. Post-treatment delivery outcomes seem to be similar to those in the general population.

文摘Objective:Previous studies indicated that aberrant circular RNA(circRNA)expression affects gene expression regulatory networks,leading to the aberrant activation of tumor pathways and promoting tumor cell growth.However,the expression,clinical significance,and effects on cell propagation,invasion,and dissemination of circRNA_001896 in cervical cancer(CC)tissues remain unclear.Methods:The Gene Expression Omnibus(GEO)datasets(GSE113696 and GSE102686)were used to examine differential circRNA expression in CC and adjacent tissues.The expression of circRNA_001896 was detected in 72 CC patients usingfluorescence quantitative PCR.Correlation analysis with clinical pathological features was performed through COX multivariate and univariate analysis.The effect of circRNA_001896 downregulation on CC cell propagation was examined using the cell counting kit-8(CCK-8)test,clonogenic,3D sphere formation,and in vivo tumorigenesis assays.Results:Intersection of the GSE113696 and GSE102686 datasets revealed an increased expression of four circRNAs,including circRNA_001896,in CC tissues.Fluorescence quantitative PCR confirmed circRNA_001896 as a circular RNA.High expression of circRNA_001896 was considerably associated with lymph node metastasis,International Federation of Gynecologists and Obstetricians(FIGO)stage,tumor diameter,and survival period in CC patients.Proportional hazards model(COX)univariate and multivariate analyses revealed that circRNA_001896 expressions are a distinct risk factor affecting CC patients’prognosis.Cellular functional experiments showed that downregulating circRNA_001896 substantially suppressed CC cell growth,colony formation,and 3D sphere-forming ability.In vivo,tumorigenesis analysis in nude mice demonstrated that downregulating circRNA_001896 remarkably reduced the in vivo proliferation capacity of CC cells.Conclusion:CircRNA_001896 is highly expressed in CC tissues and is substantially related to lymph node metastasis,FIGO stage,tumor size,and survival period in patients.Moreover,downregulating circRNA_001896 significantly inhibits both in vivo and in vitro propagation of CC cells.Therefore,circRNA_001896 might be used as a biomarker for targeted therapy in cervical cancer.
文摘BACKGROUND Cervical cancer is a rare primary tumor resulting in metastases to the breast with few cases reported in literature.Breast metastases are associated with poor prognosis.The following case highlights the diagnostic challenges associated with metastatic cervical cancer to the breast along with individualized treatment.CASE SUMMARY A 44-year-old G7P5025 with no significant past medical or surgical history presented with heavy vaginal to an outside emergency department where an exam and a pelvic magnetic resonance imaging showed a 4.5 cm heterogenous lobulated cervical mass involving upper two thirds of vagina,parametria and lymph node metastases.Cervical biopsies confirmed high grade adenocarcinoma with mucinous features.A positron emission tomography/computed tomography(PET/CT)did not show evidence of metastatic disease.She received concurrent cisplatin with external beam radiation therapy.Follow up PET/CT scan three months later showed no suspicious fluorodeoxyglucose uptake in the cervix and no evidence of metastatic disease.Patient was lost to follow up for six months.She was re-imaged on re-presentation and found to have widely metastatic disease including breast disease.Breast biopsy confirmed programmed death-ligand 1 positive metastatic cervical cancer.The patient received six cycles of carboplatin and paclitaxel with pembrolizumab.Restaging imaging demonstrated response.Patient continued on pembrolizumab with disease control.CONCLUSION Metastatic cervical cancer to the breast is uncommon with nonspecific clinical findings that can make diagnosis challenging.Clinical history and immunohistochemical evaluation of breast lesion,and comparison to primary tumor can support diagnosis of metastatic cervical cancer to the breast.Overall,the prognosis is poor,but immunotherapy can be considered in select patients and may result in good disease response.

文摘BACKGROUND Cervical dystonia(CD)is a type of muscle tone disorder that usually occurs in the neck muscles.Due to the intermittent or continuous involuntary contraction of the neck muscles,the head and neck are twisted and skewed and some postural abnormalities occur.Long-term abnormal posture or pain can cause negative emotions in patients,which can affect their quality of life.CASE SUMMARY This case report included a 37-year-old woman who was diagnosed with CD associated with anxiety and depression;the accompanying symptoms were head and neck tilt of approximately 90°to the right and mental abnormality.After two courses of acupuncture treatment,the patient’s head and neck can be maintained in a normal position,and the negative emotions can be relieved.CONCLUSION This case indicates that acupuncture can effectively improve CD and the emotional state and quality of life of patients,making it an effective alternative treatment for the condition.
文摘Background: Cervical cancer (CC) is one of the most frequent cancers and the leading cause of death from gynecological cancer in Low and middle income countries, Cameroon inclusive. Surgery is the primary treatment modality when the disease is diagnosed at early stage. Radical hysterectomy in cervical cancer has not been evaluated in recent years in Cameroon. The purpose of this study is thus to evaluate the epidemiological and clinical features and short term outcomes of patients who underwent surgery. Patients and methods: This retrospective study was conducted at the Douala Gynaeco-obstetric and Pediatric Hospital and the Douala General Hospital. Cervical cancer patients who underwent Radical hysterectomy between January 2015 and December 2020 were included. A pre-established data collection tool was used to record socio-demographic, clinical and outcomes information from patients’ files;additional outcome information was obtained from phone calls. Descriptive analysis was done using the SPSS version 26. Bivariate analysis was used to determine associations between disease and patients characteristics and occurrence of adverse postoperative outcome. P value of 0.05 was considered. Results: Sixty one patients were enrolled. Their ages ranged from 33 to 74 years with a mean age of 51.95 ± 10.29 years. Over 85% of women were married, 65.57% were unemployed and 86.88% were multiparous. Only 28% had never done cervical cancer screening. Most patients had stage IB1 to IB2 stage disease (57.1%). Less than 9% underwent radical hysterectomy and 8 of those (13.11%) suffered intraoperative complications. Twenty-five patients (40.98%) presented immediate and short term complications. There was no significant association between the disease or patients’ characteristics and adverse outcomes. Conclusion: Cervical cancer patients are relatively young in our settings and only 9% of them reach the hospital at early stage. Postoperative adverse outcomes rate is higher than that reported in the literature. Sensitization on screening and awareness of early symptoms can reverse the situation.
文摘Background: Cervical Intraepithelial neoplasia treatments have become essential interventions to manage cervical lesions. Majority of the recipients of these treatments are women within the reproductive age group, who according to literature may be at risk of adverse pregnancy outcomes. This pilot study is part of a study investigating adverse pregnancy outcomes among women who received Cryotherapy, Thermal ablation and Loop Electrosurgical Excision Procedure compared to the untreated women in Zambia. Materials and Methods: This descriptive study analyzed records of 886 (n = 443 treated and n = 443 untreated) women aged 15 - 49 years. The women were either screened with Visual Inspection with Acetic Acid or treated for Cervical Intraepithelial neoplasia at the Adult Infectious Disease Centre between January 2010 and December 2020. Women meeting the criteria were identified using the Visual Inspection with Acetic Acid screening records and telephone interviews to obtain the adverse pregnancy outcome experienced. Data were analysed using STATA version 16 to determine the prevalence and obtain frequency distribution of outcomes of interest. Univariate and multivariable binary logistic regression estimated odds of adverse pregnancy outcomes across the three treatments. Results: The respondents were aged 15 to 49 years. Adverse pregnancy outcomes were observed to be more prevalent in the treatment group (18.5%) compared to the untreated group (5.4%). Normal pregnancy outcomes were lower in the treated (46.3%;n = 443) than the untreated (53.7%;n = 443). The treated group accounted for the majority of abortions (85.2%), prolonged labour (85.7%) and low birth weight (80%), whereas, the untreated accounted for the majority of still births (72.7%). Women treated with cryotherapy (aOR = 2.43, 95% CI = 1.32 - 4.49, p = 0.004), thermal ablation (aOR = 6.37, 95% CI = 0.99 - 41.2, p = 0.052) and Loop Electrosurgical Excision Procedure (aOR = 9.67, 95% CI = 2.17 - 43.1, p = 0.003) had two-, six- and ten-times higher odds of adverse pregnancy outcomes respectively, relative to women who required no treatment. Conclusion: Adverse pregnancy outcomes are prevalent among women who have received treatment in Zambia. The findings indicate that treating Cervical Intraepithelial Neoplasia has been linked to higher chances of experiencing abortion, delivering low birth weight babies and enduring prolonged labor that may result in a caesarean section delivery. Cervical neoplasia treatments, particularly Loop Electrosurgical Excision Procedure, are associated with significantly increased odds of adverse pregnancy outcomes. It is essential to include information about prior Cervical Intraepithelial neoplasia treatment outcomes in obstetric care.
文摘Cervical meningoceles are the least common forms of spina bifida, representing between 4% to 8% of all spinal dysraphisms. They are not accompanied by neurological deficit in childhood but attached cord syndrome can occur with growth. Surgical treatment, in addition to avoiding rupture and correcting the aesthetic damage, will preserve neurological functions. We report 2 cases that we took care of. They are a 5-month-old infant and a 3-year-old girl. The first presented a 7 cm rounded meningocele pedunculated through the C1 lamina defect. The second presented an 8.6 cm polylobed meningocele pedunculated through the C2 lamina defect. They both underwent surgery with good progress.

文摘Background:CD8 positive T lymphocytes and natural killer(NK)cells in the peripheral blood of cervical cancer patients exhibit varying sensitivities to radiotherapy and chemotherapy.Methods:A total of 50 healthy peoples and 60 cervical cancer patients were recruited.The patients with cervical cancer were separated into two groups:radiation and chemotherapy,and blood sample were collected before and after treatment.Data on the proportion of CD8 positive T lymphocytes and NK cells were gathered for analytical evaluation.Results:Compared to healthy individuals,patients with cervical cancer exhibit a reduced proportion of CD8 positive T cells within their peripheral blood.And for patients with cervical cancer,radiation therapy has been found to be more effective than chemotherapy in increasing the proportion of CD8 positive T lymphocytes and NK cells.Conclusions:These results suggest that radiation therapy increases the levels of CD8 positive T lymphocytes and NK cells within the peripheral blood of patients with cervical cancer.The study hypothesis that the changes in the percentage of CD8 positive T lymphocytes may serve as a potential indicator for predicting treatment efficacy.
文摘BACKGROUND Charcot neuroarthropathy(CN)is a systemic disease characterized by progressive bone loss and destruction,which is usually closely related to diabetes,HIV,etc.However,CN caused by syringomyelia accounts for only 5%of CN cases;the shoulder and elbow are most often involved,and the hip joint is rarely affected.As a rare factor,cervical spondylotic myelopathy(CSM)can be associated with syringomyelia,which is scarcely reported in the literature.Here,we present the first case report to date of CN of the hip caused by syringomyelia secondary to CSM.CASE SUMMARY We describe a 76-year-old male patient who was diagnosed with CSM due to neck pain and weakness of limbs 16 years ago.Four years ago,he noticed recurrent swelling of the right hip with pain and was diagnosed with degenerative arthritis.Recently,however,his symptoms gradually worsened,and because of progressive pain,destabilization and weakness of the right hip,he was admitted to our hospital.Through systematic physical,radiographic and laboratory examinations,we finally reached a diagnosis:CN of the right hip associated with syringomyelia secondary to CSM.After comprehensive evaluation of the patient's condition,we performed right total hip arthroplasty.During the follow-up,the patient felt well clinically and could walk independently with a knee brace.CONCLUSION We suggest a possible etiological association between CSM and syringomyelia,which may reflect a potential pathogenesis of CN.We encourage clinicians to actively carry out a detailed medical history and comprehensive physical and imaging examinations in patients with joint lesions,especially chronic shoulder neck pain,to rule out the possibility of this association,which plays a crucial role in the early diagnosis of CN.Arthroplasty may no longer be an absolute contraindication to surgical treatment of CN.Reasonable selection of the surgical strategy can markedly improve the clinical symptoms and quality of life of patients.
文摘Cervical spondylotic myelopathy(CSM) is the most common cause of spinal cord dysfunction and is caused by static or dynamic repeated compression of the spinal cord resulting from degenerative arthritis of the cervical spine and some biological injuries to the cervical spine. The T2 signal change on conventional magnetic resonance imaging(MRI) is most commonly associated with neurological deficits. Diffusion tensor imaging and MR spectroscopy show altered microstructure and biochemistry that reflect patient-specific pathogenesis and can be used to predict neurological outcome and response to intervention. Functional MRI can help to assess the neurological functional recovery after decompression surgery for CSM.
