Introduction: Late pregnancies are considered a public health problem linked to maternal mortality due to their complications. These risks, which worsen with maternal age, should be better known and taken into account in monitoring these pregnancies. Objective: To evaluate the impact of age on the prevalence of obstetric and neonatal complications among parturients of 40 years old and over. Methodology: This was an 11-year retrospective analytical case control study from January 1, 2007 to December 31, 2017. The study population was female patients of 40 years old or older for cases and female patients younger than 40 years of control case. Results: In total, we collected 640 cases of parturients of 40 years old and over out of a total of 84,234 deliveries during the study period;i.e. a frequency of 0.76%. Spontaneous abortion increased in patients of 40 and over with 8.28%. Hypertension and diabetes were higher of women of 40 and over, 52.65%. Concerning the method of admission: 55% of parturients of 40 and over were referrals. Incidents occurring among women of 40 and over were more pronounced than in control cases. Complications during vaginal delivery, cervical tear, perineal tear, uterine dehiscence and uterine rupture are high in our cases, i.e. 11.88%;3.59%;2.19%;2.66. During our study, depending on the type of delivery, the cesarean rate was much higher among women of 40 and over than among control cases, i.e. 54.22% versus 12.24%. Hemorrhages in the 3rd trimester were the main indications for cesarean section. Hemorrhages in the 3rd trimester were more frequent with women of 40 and over, i.e. 10.47%;5.94% versus 1.74% and 0.42%. As for the different types of malformations in parturients, women under 40 years old fetal malformations were absent in 92.29%, on the other hand they were more frequent in patients with 40 years and over, i.e. a normal frequency of 36.72%. Conclusion: Pregnancy at a late age exposes the elderly patient and the newborn to several risks. During this study, an increase in maternal-fetal morbidity was observed with aged women. 展开更多

Acrodermatitis enteropathica is a rare autosomal recessive genetic disorder characterised by periorificial dermatitis, alopecia and diarrhoea. It is caused by a mutation in the gene that codes for a membrane protein that binds zinc. We report a case in a 7-month-old girl, admitted with altered general condition and scaly, pustular erythematous lesions, initially located in the occipital and cervical regions, and secondarily inguinal and on the knees. Management and outcome in this patient? Genetic assay was not available to confirm this rare genetic disease. A delay in establishing the diagnosis and a disastrous outcome did not save the patient despite the administration of zinc. 展开更多

BACKGROUND Eccrine porocarcinoma(EPC)is a rare skin tumor that mainly affects the elderly population.Tumors often present with slow growth and a good prognosis.EPCs are usually distinguished from other skin tumors using histopathology and immunohistochemistry.However,surgical management alone may be inadequate if the tumor has metastasized.However,currently,surgical resection is the most commonly used treatment modality.CASE SUMMARY A seventy-four-year-old woman presented with a slow-growing nodule in her left temporal area,with no obvious itching or pain,for more than four months.Histopathological examination showed small columnar and short spindle-shaped cells;thus,basal cell carcinoma was suspected.However,immunohistochemical analysis revealed the expression of cytokeratin 5/6,p63 protein,p16 protein,and Ki-67 antigen(40%),and EPC was taken into consideration.The skin biopsy was repeated,and hematoxylin and eosin staining revealed ductal differentiation in some cells.Finally,the patient was diagnosed with EPC,and Mohs micrographic surgery was performed.We adapted follow-up visits in a year and not found any recurrence of nodules.CONCLUSION This case report emphasizes the diagnosis and differentiation of EPC. 展开更多

Introduction: Maternal mortality constitutes a public health problem and its rate is an indicator of a country’s development. Among the causes of maternal and perinatal death, high blood pressure associated with pregnancy occupies a significant part. It represents 5% of direct maternal deaths. Objective: to study the maternal and perinatal prognosis of high blood pressure during pregnancy in the Tenenkou reference health center in Mali. Methodology: This was a descriptive, analytical and retrospective cross-sectional study over a period of twelve months from January 1, 2021 to December 31, 2021 and involving 144 cases of high blood pressure associated with pregnancy. Results: We obtained a frequency of 11.75%. The majority of patients 70.9% were aged between 20 - 35 years. The important risk factor found was young age. During our study, 46.5% of patients had performed at least one CPN and only 13.9% performed 04 CPN. Pre-eclampsia was the most common type of high blood pressure during pregnancy, i.e. 61.1%. Eclampsia and retroplacental hematoma were the most common maternal complications, respectively 27.8% and 11.1%. The most common fetal complications were premature births and fetal distress with 20.9% and 17.4% respectively. Conclusion: Hypertension associated with pregnancy still remains a major cause of maternal-fetal morbidity and mortality in our context where diagnosis is often late. The main clinical form was preeclampsia. Eclampsia and retroplacental hematoma were the most frequent maternal complications. Fetal complications were mainly prematurity and fetal distress. 展开更多

Introduction: Uterine fibroid is a mixed mesenchymal tumor, developing from smooth muscle cells of the myometrium, separated by connective tissue. The majority of fibroids are asymptomatic and do not require any intervention or other exploratory measures. However, in some cases fibroids are symptomatic, their treatment should aim to improve symptoms and quality of life. Objectives: Describe the epidemiological-clinical aspects of uterine fibroids in the gynecology and obstetrics department of the reference health center of commune VI of the Bamako district. Methodology: This was a retrospective descriptive study carried out over a period of one year. It concerns all patients seen in consultation in the gynecology and obstetrics department of the reference health center of commune VI. Results: during the study period, the uterine fibroid frequency was 1.80%. During this same period, fibroids represented 5.59% of gyneco-obstetric pathologies operated on in the department. The 30 - 45 year old age group was the most represented with a frequency of 75.63%. The average age was 36.87 years ± 6.2 years with extremes of 25 and 63 years. Married women were the most represented 97.48%. The vast majority of our patients 95.8% were not postmenopausal. The multigravidas were the most represented, i.e. 37.50% with a large part of the pauciparous 41.29%. In our patients, 96.64% had a clinical symptom on their fibroid with the main reason for consultation being the sensation of a pelvic mass in 97.48%. We recorded three cases of infertility as associated factors. Ultrasound was performed in all patients. The location of the myxomatous nuclei was subserosal in the majority in 42.86% and with multiple nodules in 84.85% of cases. The main indication for myomectomy was the failure of medical treatment in 86.49% of cases. Surgical treatment was mainly a myomectomy 93.30%, a hysterectomy was indicated in 6.70%. No cases of death were recorded. Conclusion: Uterine fibroid is a gynecological pathology that exists in our department;its frequency is estimated at 5.59%. For better management of fibroids, it is necessary to have a good knowledge of the factors favoring the occurrence of uterine fibroids, their growth and the symptoms to prevent the appearance of it or even at best to operate. This prevention must be a concern for public health because fibromatous pathology is frequent, costly and hampers quality of life. 展开更多

Objective: To examine the prevalence of cutaneous disorders in children under 5 years old who attended a rural hospital in Southern Ethiopia.Methods: A prospective cross-sectional study was conducted from January 26 to February 20, 2015 in children under 5 years old who attended Gambo Rural Hospital in West Arsi of the Oromia Region, Ethiopia.Results: A total of 324 children were included(59.6% male) whose median age was 16.4months. In total, 147 children [45.4%; 95% confidence interval(CI): 40.0%–50.8%]under 5 years had a skin problem, of which 101(68.7%) consulted for that reason. The other 46(31.3%) consulted for a general health problem and the dermatological condition was a secondary finding during the physical exploration. In 93 children(28.7%; 95% CI:20%–33.8%), it was the main disease, and in 54 children(16.5%; 95% CI: 13.0%–21.1%)it was concomitant with other diseases. The most common dermatological disease was scabies(n = 44, 13.6%; 95% CI: 10.3%–17.7%). Impetigo was diagnosed in 32 children(9.9%; 95% CI: 7.1%–13.3%), of which 23(71.9%) had complicated impetigo. Nineteen children(5.9%; 95% CI: 3.8%–9.0%) had eczema, 10(3.1%) had eczema associated to other conditions. The following most frequent skin problems were tinea(n = 9; 2.8%),infected wound and ulcer(n = 7; 2.2%), and burns(n = 6; 1.9%).Conclusions: Skin problems, mainly scabies, impetigo, and eczema were common in young children attended at a rural hospital in Southern Ethiopia. Children under 5 years should be examined thoroughly to rule out skin diseases, especially scabies. 展开更多

Psoriasis is an inflammatory skin disease that is intricately linked to oxidative stress.Antioxidation and inhibition of abnormal proliferation of keratinocytes are pivotal strategies for psoriasis.Delivering drugs with these effects to the site of skin lesions is a challenge that needs to be solved.Herein,we reported a nanotransdermal delivery system composed of all-trans retinoic acid(TRA),triphenylphosphine(TPP)-modified cerium oxide(CeO2)nanoparticles,flexible nanoliposomes and gels(TCeO_(2)-TRA-FNL-Gel).The results revealed that TCeO_(2)synthesized by the anti-micelle method,with a size of approximately 5 nm,possessed excellent mitochondrial targeting ability and valence conversion capability related to scavenging reactive oxygen species(ROS).TCeO_(2)-TRA-FNL prepared by the film dispersion method,with a size of approximately 70 nm,showed high drug encapsulation efficiency(>96%).TCeO_(2)-TRA-FNL-Gel further showed sustained drug release behaviors,great transdermal permeation ability,and greater skin retention than the free TRA.The results of in vitro EGF-induced and H2O2-induced models suggested that TCeO_(2)-TRA-FNL effectively reduced the level of inflammation and alleviated oxidative stress in HaCat cells.The results of in vivo imiquimod(IMQ)-induced model indicated that TCeO_(2)-TRA-FNL-Gel could greatly alleviate the psoriasis symptoms.In summary,the transdermal drug delivery system designed in this study has shown excellent therapeutic effects on psoriasis and is prospective for the safe and accurate therapy of psoriasis. 展开更多

Girls are more often affected than boys and the female predominance increases significantly with age. The initial manifestations are highly variable with an insidious and progressive onset. Non-specific symptoms include fever, anorexia, weight loss and asthenia. Pericarditis is the most common cardiac manifestation in systemic lupus erythematosus (SLE), occurring in 10% to 40% of cases. The biological elements of the diagnosis and follow-up of pediatric SLE are identical to those of adults and are based on regular measurement of complement, native anti-DNA antibodies, and inflammatory findings. Treatment is essentially based on corticosteroid therapy. 展开更多

Scleroderma (or systemic sclerosis) is a disease characterized by abnormalities in the functioning of small blood vessels and the immune system, ultimately leading to inflammation and excessive fibrosis of the skin and various organs, including the heart. Management must be multidisciplinary, to avoid complications that are often serious. We report the case of a 20-year-old patient with no known cardiovascular history who consults for dyspnea, and retrosternal pain associated with a dry cough. On physical examination, she had tachycardia, swelling of the lower limbs, jugular turgidity, and deafening heart sounds. Cardiac Doppler ultrasound shows dilation of the right cavities, paradoxical septum and significant pulmonary arterial hypertension, pericardial effusion of medium abundance. On oral examination, it presents an ulceration of the lips, dermatological examination finds scattered hypo chromic spots in the body, more accentuated in the face. Before the hypo chromic dermatosis, a dermatological consultation was carried out with an autoimmune assessment that came back positive for systemic scleroderma. 展开更多

Meloxicam(MLX) is efficient in relieving pain and inflammatory symptoms, which, however, is limited by the poor solubility and gastrointestinal side effects. The objective of this study is to develop a nanocrystal formulation to enhance transdermal delivery of MLX. MLX nanocrystals were successfully prepared by the nanoprecipitation technique based on acidbase neutralization. With poloxamer 407 and Tween 80(80/20, w/w) as mixed stabilizers,MLX nanocrystals with particle size of 175 nm were obtained. The crystalline structure of MLX nanocrystals was confirmed by both differential scanning calorimetry and X-ray powder diffractometry. However, the nanoprecipitation process reduced the crystallinity of MLX.Nanocrystals increased both in vitro and in vivo transdermal permeation of MLX compared with the solution and suspension counterparts. Due to the enhanced apparent solubility and dissolution as well as the facilitated hair follicular penetration, nanocrystals present a high and prolonged plasma MLX concentration. And 2.58-and 4.4-fold increase in AUC0 →2 4 h was achieved by nanocrystals comparing with solution and suspension, respectively. In conclusion, nanocrystal is advantageous for transdermal delivery of MLX. 展开更多

AIM: Eph receptor tyrosine kinases and their membrane bound receptor-like ligands, the ephrins, represent a bi-directional cell-cell contact signaling system that directs epithelial movements in development. The meaning of this system in the adult human gut is unknown. We investigated the Eph/ephrin mRNA expression in the intestinal epithelium of healthy controls and patients with inflammatory bowel disease (IBD).METHODS: mRNA expression profiles of all Eph/ephrin family members in normal small intestine and colon were established by real-time RT-PCR. In addition, differential expression in IBD was investigated by cDNA array technology, and validated by both real-time RT-PCR and immunohistochemistry. Potential effects of enhanced EphB/ephrin-B signaling were analyzed in an in vitro IEC-6 cell scratch wound model.RESULTS: Human adult intestinal mucosa exhibits a complex pattern of Eph receptors and ephrins. Beside the known prominent co-expression of EphA2 and ephrinA1,we found abundantly co-expressed EphB2 and ephrin-B1/2.Interestingly, cDNA array data, validated by real-time PCR and immunohistochemistry, showed upregulation of ephrin-B2 in both perilesional and lesional intestinal epithelial cells of IBD patients, suggesting a role in epithelial homeostasis. Stimulation of ephrin-B signaling in ephrinB1/2 expressing rat IEC-6-cells with recombinant EphB1Fc resulted in a significant dose-dependent acceleration of wound closure. Furthermore, fluorescence microscopy showed that EphB1-Fc induced coordinated migration of wound edge cells is associated with enhanced formation of lamellipodial protrusions into the wound, increased actin stress fiber assembly and production of laminin at the wound edge.CONCLUSION: EphB/ephrin-B signaling might represent a novel protective mechanism that promotes intestinal epithelial wound healing, with potential impact on epithelial restitution in IBD. 展开更多

Mycosis fungoides(MF),the most common type of cutaneous T-cell lymphoma,has various unspecific clinical and histological characteristics.Its early diagnosis is challenging.The application of T-cell receptor(TCR) gene clonal rearrangement to the diagnosis of MF has been widely studied.In this study,we used polymerase chain reaction(PCR) to investigate the diagnostic significance of detecting TCR-γ and-β gene clonal rearrangement in the early diagnosis of mycosis fungoides.PCR for TCR-γ and TCR-β gene rearrangement was performed on 19 patients with suspected early MF,6 with typical MF,and 6 with chronic dermatitis.Of the 19 patients with suspected early MF,13 had TCR-γ gene clonal rearrangement,whereas none had TCR-β gene clonal rearrangement.All patients with typical MF had TCR gene clonal rearrangement,in which 4 showed TCR-γ clonal rearrangement,1 showed TCR-β gene clonal rearrangements,and 1 showed both.No patients with chronic dermatitis had TCR gene clonal rearrangement.These results indicate that TCR gene clonal rearrangement analysis is a useful tool in diagnosing early MF.TCR-γ gene is recommended to the routine analysis,whereas TCR-β gene has potential in combination toward intractable cases. 展开更多

AIM: Eph receptors and ephrin ligands play a pivotal role in development and tissue maintenance. Since previous data have indicated an involvement of ephrin-B2 in epithelial healing, we investigated the gene expression and downstream signaling pathways induced by ephrin-B mediated cell-cell signaling in intestinal epithelial cells.METHODS: Upon stimulation of ephrin-B pathways in IFC-6 cells with recombinant rat EphB1-Fc, gene expression was analyzed by Affymetrix(R) rat genome 230 high density arrays at different time points. Differentially expressed genes were confirmed by real-time RT-PCR. In addition, MAP kinase pathways and focal adhesion kinase (FAK) activation downstream of ephrin-B were investigated by immunoblotting and fluorescence microscopy.RESULTS: Stimulation of the ephrin-B reverse signaling pathway in IEC-6 cells induces predominant expression of genes known to be involved into wound healing/cell migration, antiapoptotic pathways, host defense and inflammation. Cox-2, c-Fos, Egr-1, Egr-2, and MCP-1 were found among the most significantly regulated genes.Furthermore, we show that the expression of repairrelated genes is also accompanied by activation of the ERK1/2 MAP kinase pathway and FAK, two key regulators of epithelial restitution.CONCLUSION: Stimulation of the ephrin-B reverse signaling pathway induces a phenotype characterized by upregulation of repair-related genes, which may partially be mediated by ERK1/2 pathways. 展开更多

The genovariation of endothelin receptor type B(EDNRB) was identified in a Chinese family with Waardenburg syndrome type I(WS1) in the present study. WS1 was diagnosed in a 19-year-old young man, his older sister and aunt according to WS consortium criteria. After extracting genomic DNA from the peripheral blood samples, the coding exons and intronic regions of EDNRB were sequenced. A missense heterozygous mutation was found in the coding region of exon 2 in the EDNRB gene on chormosome 13 q22.3 of the proband. The same mutation was detected in the proband’s afflicted paternal aunt and first older sister. Subsequent polyphen analysis and three-dimensional modeling confirmed that the c.469 A>G heterozygous mutation in EDNRB was possibly pathogenic. This is the first report of EDNRB mutation as a potential disease-causing mutation in Chinese patients with WS1. 展开更多

The differentiation syndrome is an inflammatory reaction with increased capillary permeability that occurs in up to 25% of patients with acute promyelocytic leukemia treated with all-trans retinoic acid. A 50-year-old man with acute promyelocytic leukemia underwent chemotherapy with idarubicin and all-trans retinoic acid. On day +21 the patient developed pruritic prepatelar papules as well as several 10 mm subcutaneous nodules in both thighs accompanied by persistent fever. On the day +25 the patient presented with bilateral pulmonary crackles, infiltrates in the right lower lobe and severe hypotension which required dopamine infusion. Biopsy of one of the thighs nodules was performed. A Sweet syndrome associated to a differentiation syndrome was suspected. All-trans retinoic acid therapy was discontinued and dexamethasone was administered. In 48 h the patient showed remission of the fever and the infiltrates and the skin lesions acquired a residual aspect. It is debatable whether these two syndromes are distinct entities with common mechanisms or whether they are poles of the same spectrum. Dermatologists and hematologists must be aware of these two syndromes and its pathophysiologic association. 展开更多

BACKGROUD Follicular dendritic cell(FDC)sarcomas are rare neoplasms that occur predominantly in the lymph nodes.They can also occur extranodally.Extranodal FDC sarcomas most commonly present as solitary masses.Inflammatory pseudotumor(IPT)-like FDC sarcomas,a subcategory of FDC sarcomas,are rarer than other sarcoma subtypes.They are composed of spindle or ovoid neoplastic cells and exhibit an admixture of plasma cells and prominent lymphoplasmacytic infiltration.Paraneoplastic pemphigus(PNP),also known as paraneoplastic autoimmune multiorgan syndrome,is a rare autoimmune bullous disease that is associated with underlying neoplasms.PNP has a high mortality,and its early diagnosis is usually difficult.CASE SUMMARY We describe a 27-year-old woman who presented with stomatitis,conjunctivitis,and skin blisters and erosions as her first symptoms of PNP with an intraabdominal IPT-like FDC sarcoma.The patient underwent surgical tumor resection and received tapering oral corticosteroid treatment.She showed no recurrence at the 1-year follow-up.CONCLUSION IPT-like FDC sarcomas are rare underlying neoplasms that have an uncommon association with PNP.PNP-associated FDC sarcomas predominantly occur in intra-abdominal sites and suggest a poor prognosis.Surgical resection is an essential and effective treatment for PNP and primary and recurrent FDC sarcomas. 展开更多
