Endometrial microbiota alteration in female patients with endometrial polyps based on 16S rRNA gene sequencing analysis.

Introduction: The potential role of the endometrial microbiota in the pathogenesis of endometrial polyps (EPs) warrants further investigation, given the current landscape of limited and inconclusive research findings. We aimed to explore the microecological characteristics of the uterine cavity in patients with EPs and investigate the potential of endometrial microbiota species as novel biomarkers for identifying EPs. Methods: Endometrial samples were collected from 225 patients who underwent hysteroscopies, of whom 167 had EPs, whereas 58 had non- hyperproliferative endometrium status. The endometrial microbiota was assessed using 16S rRNA gene sequencing. We characterized the endometrial microbiota and identified microbial biomarkers for predicting EPs. Results: The endometrial microbial diversity and composition were significantly different between the EP and control groups. Predictive functional analyses of the endometrial microbiota demonstrated significant alterations in pathways involved in sphingolipid metabolism, steroid hormone biosynthesis, and apoptosis between the two groups. Moreover, a classification model based on endometrial microbial ASV-based biomarkers along with the presence of abnormal uterine bleeding symptoms achieved powerful classification potential in identifying EPs in both the discovery and validation cohorts. Conclusion: Our study indicates a potential association between altered endometrial microbiota and EPs. Endometrial microbiota-based biomarkers may prove valuable for the diagnosis of EPs.

Gas Where It Shouldn't Be! Imaging Spectrum of Emphysematous Infections in the Abdomen and Pelvis.

OBJECTIVE. The purpose of this article is to review the spectrum, etiopathogenesis, clinical presentation, imaging features, differential diagnoses, and management of emphysematous infections of the abdomen and pelvis. CONCLUSION. Emphysematous infections are associated with high morbidity and mortality and thus need urgent medical and surgical interventions. CT is the most sensitive modality to detect gas; CT provides definitive diagnosis in most cases and can depict the extent of involvement.

New Opportunities for Endometrial Health by Modifying Uterine Microbial Composition: Present or Future?

Current knowledge suggests that the uterus harbours its own microbiota, where the microbes could influence the uterine functions in health and disease; however, the core uterine microbial composition and the host-microbial relationships remain to be fully elucidated. Different studies are indicating, based on next-generation sequencing techniques, that microbial dysbiosis could be associated with several gynaecological disorders, such as endometriosis, chronic endometritis, dysfunctional menstrual bleeding, endometrial cancer, and infertility. Treatments using antibiotics and probiotics and/or prebiotics for endometrial microbial dysbiosis are being applied. Nevertheless there is no unified protocol for assessing the endometrial dysbiosis and no optimal treatment protocol for the established dysbiosis. With this review we outline the microbes (mostly bacteria) identified in the endometrial microbiome studies, the current treatments offered for bacterial dysbiosis in the clinical setting, and the future possibilities such as pro- and prebiotics and microbial transplants for modifying uterine microbial composition.

Microbiological and clinical characteristics of Streptococcus gallolyticus subsp. pasteurianus infection in China.

BACKGROUND: Infections by Streptococcus gallolyticus subsp. pasteurianus (SGSP) is often underestimated. Herein, the epidemiological features and resistant characteristics of SGSP in mainland China are characterized to enable a better understanding of its role in clinical infections. METHODS: In the present work, 45 SGSP isolates were collected from the samples of bloodstream, urine, aseptic body fluid, and fetal membrane/placenta from patients in 8 tertiary general hospitals of 6 cities/provinces in China from 2011 to 2017. The identification of all isolates was performed using traditional biochemical methods, 16S rRNA and gyrB sequencing, followed by the characterization of their antibiotic resistance profiling and involved genes. RESULTS: Among 34 non-pregnancy-related patients, 4 (4/34,11.8%) patients had gastrointestinal cancer, 10 (10/34, 29.4%) patients had diabetes, and one patient had infective endocarditis. Moreover, 11 cases of pregnant women were associated with intrauterine infection (9/11, 81.2%) and urinary tract infection (1/11, 9.1%), respectively. Except one, all other SGSP isolates were correctly identified by the BD Phoenix automated system. We found that all SGSP isolates were phenotypically susceptible to penicillin, ampicillin, cefotaxime, meropenem, and vancomycin. Forty strains (40/45, 88.9%) were both erythromycin and clindamycin-resistant, belonging to the cMLSB phenotype, and the majority of them carried erm(B) gene (39/40, 97.5%). Although the cMLSB/erm(B) constituted the most frequently identified phenotype/genotype combination (25/40, 62.5%) among all erythromycin-resistant cMLSB isolates, erm(B)/erm(A), erm(B)/mef(A/E), and erm(B)/erm(T) was detected in 7, 4, and 3 isolates, respectively. Furthermore, 43 strains (43/45, 95.6%) were tetracycline-resistant, and out of these, 39 strains (39/45, 86.7%) carried tet(L), 27(27/45, 60.0%) strains carried tet(O), and 7 (7/45, 15.6%) strains carried tet(M), alone or combined, respectively. All erythromycin-resistant isolates were also resistant to tetracycline. CONCLUSIONS: It is important to study and draw attention on SGSP, an underreported opportunistic pathogen targeting immunodeficient populations, notably elderly subjects, pregnant women and neonates.

[Rare location of tuberculosis: endometrial tuberculosis]. / Une localisation rare de la tuberculose: la tuberculose endométriale.

Tuberculosis is a public health problem, especially in the developing countries. Bacillary pulmonary tuberculosis is the most common form of tuberculosis while genital tuberculosis is rare and underdiagnosed. We here report a case of endometrial tuberculosis. The study involved a 72-year old female patient with SC hemoglobinopathy consulting her gynecologist because of chronic leukorrhea. Cytobacteriologic assessment of vaginal swabs showed Streptococcus agalactatiae. Despite suitable antibiotic therapy, the evolution was marked by the persistence of leukorrhea. Pelvic ultrasonography objectified thickened endometrium, appearing as hyperechoic at the base of the uterus. This was suggestive of endometrial cancer. Anatomo-pathological examination of endometrial curettage samples showed granulomatous endometritis suggesting follicular tuberculosis. Outcome was favorable under antituberculosis treatment. In TB endemic areas, genital tuberculosis is not exceptional and should be suspected in patients with chronic leukorrhea despite suitable treatment.

Endometrial histopathology, bacteriology and cytology outcomes in mares with early embryonic death (EED): a field study.

Early embryonic death (EED) is one of the causes of infertility in the mare. We compared endometrial environment in 9 mares with EED and 13 mares in diestrus phase. Cotton swab (CS), cytobrush (CB) and uterine biopsy (B) samples were obtained for the cytological, bacteriological and histopathological examinations. In the first step we compared CS and CB methods to biopsy as a reference method, as B revealed the highest number of positive results in cytological and bacteriological examinations in both groups. In turn, we also compared cytological, bacteriological and histopathological findings between EED and control animals using the B sampling. Although the differences between these groups were not statistically significant (p≥0.05), there was a tendency to a higher prevalence of subclinical endometritis in the control group, than in the EED group (62% vs 22%). In general, positive bacteriological results were similar in both groups (62% vs 55%), whereas positive cytological results were higher in the control group (62% vs 22%; p≥0.05). In histopathological examination in EED mares endometrial degeneration was better expressed (all mares were with grades IIB and III on the Kenney-Doig scale); however, the differences between both groups were not statistically significant (p≥0.05). We could not confirm a clear difference in uterine environment between the two groups. Moreover, the uterine biopsy seemed to be the most reasonable sampling method for diagnosis of endometrial state.

A model of clinical endometritis in Holstein heifers using pathogenic Escherichia coli and Trueperella pyogenes.

Bacterial infection of the uterus causes clinical endometritis in 15 to 20% of postpartum dairy cows and reduces fertility, even after the resolution of disease. However, it is difficult to disentangle the mechanisms linking reduced fertility with endometritis because cows have multiple confounding postpartum conditions. The aim of the present experiment was to develop an in vivo model of clinical endometritis in Holstein heifers using pathogenic Escherichia coli and Trueperella pyogenes. Estrous cycles of heifers were synchronized using a 5-d Co-Synch protocol, and subsequently received exogenous progesterone to elevate circulating progesterone at the time of uterine infusion. Endometrial scarification was performed before uterine infusion of live pathogenic Escherichia coli and Trueperella pyogenes, or sterile vehicle. Effects of infusion were evaluated by measuring rectal temperature, plasma haptoglobin, hematology, grading pus in the vaginal mucus, quantifying 16S rRNA in vaginal mucus, and transrectal ultrasonography. Bacterial infusion increased the median vaginal mucus to grade 2 by d 3 postinfusion, and to grade 3 from d 4 to 6 postinfusion. Control heifers maintained a median vaginal mucus grade ≤1 from d 1 to 6. Transrectal ultrasound revealed the accumulation of echogenic fluid in the uterus of heifers following bacterial infusion, which was absent in control heifers. Total 16S rRNA in vaginal mucus was elevated in bacteria-infused heifers compared with control heifers at d 5. Rectal temperature was increased in bacteria-infused heifers. Plasma haptoglobin, general health, and appetite did not differ between groups. As indicated by increased vaginal mucus grade after bacterial infusion and absence of systemic signs of illness, this model successfully induced symptoms resembling clinical endometritis in virgin Holstein heifers. The model allows the isolation of effects of uterine disease on fertility from confounding factors that can occur during the postpartum period in dairy cows.

PGE2 increases inflammatory damage in Escherichia coli-infected bovine endometrial tissue in vitro via the EP4-PKA signaling pathway.

Endometritis is the most common bovine uterine disease following parturition. The role of prostaglandin E2 (PGE2) in the regulation of endometrial inflammation and repair is well understood. Excess PGE2 is also generated in multiple inflammatory diseases, including endometritis. However, it remains unclear whether PGE2 is associated with pathogen-induced inflammatory damage to the endometrium. To clarify the role of PGE2 in pathogen-induced inflammatory damage, this study evaluated the production of PGE2, inflammatory factors, and damage-associated molecular patterns (DAMPs) in cultured Escherichia coli-infected bovine endometrial tissue. PGE2 production was significantly higher in E. coli-infected tissue, and in E. coli-infected tissue treated with 15-prostaglandin dehydrogenase (15-PGDH) inhibitors, as compared to uninfected tissue. Phospholipase A2 (PLA2), cyclooxygenase-2 (COX-2), and microsomal prostaglandin E synthase-1 (mPGES-1) were also upregulated in E. coli-infected tissue, while concentrations of arachidonic acid (AA), leukotrienes, DAMPs, and other proinflammatory factors increased. The accumulation of PGE2 clearly damaged the cultured tissue. Treatment with the COX-2, mPGES-1, EP4, and protein kinase A (PKA) inhibitors decreased the production of PGE2, inflammatory factors, and DAMPs, simultaneously alleviating the E. coli-induced endometrial tissue damage. Therefore, the PGE2 that was generated by COX-2 and mPGES-1 accumulated, and this pathogenic PGE2 increased inflammatory damage by upregulating inflammatory factors and DAMPs in E. coli-infected bovine endometrial tissue. This upregulation of inflammatory factors and DAMPs might be regulated by the EP4-PKA signaling pathway.

[Life-threatening intrauterine infection with Clostridium perfringens].

In this case report, a 40-year-old woman with a history of a uterine leiomyoma presented with abdominal pain and fever. Initially, her symptoms were associated with a bleeding from an ovarian cyst seen on a CT scan of the abdomen showing free intraperitoneal fluid surrounding the internal genitals. Meanwhile, her blood cultures came out positive for Clostridium perfringens, and her condition deteriorated despite intravenous antibiotics. A new CT scan revealed intrauterine gas development. A laparotomy was performed with removal of the internal genitals, and the patient improved on continuous antibiotics.

Endometrial tuberculosis among patients undergoing endometrial biopsy at Tikur Anbesa specialized hospital, Addis Ababa, Ethiopia.

BACKGROUND: Female genital tuberculosis (FGTB) is known to cause severe tubal disease leading to infertility and its incidence closely parallels with the overall prevalence of tuberculosis (TB) in a community. Its magnitude is underreported because diagnosis is difficult and requires invasive techniques. In this study we determined the prevalence of endometrial tuberculosis and characterized isolates among women who underwent endometrial biopsy for evaluation of various conditions at a Tikur Anbessa Specialized Hospital (TAHS), Addis Ababa, Ethiopia. METHODS: A cross sectional study was conducted on 152 consecutive gynecologic patients who underwent endometrial biopsy for different gynecologic diseases. Endometrial tissue taken for routine histopathology examination was shared after informed consent was obtained from the patient and subjected to polymerase chain reaction (PCR) and culture for Mycobacterium tuberculosis (Mtb). RESULTS: The prevalence of endometrial TB in this study by IS1081PCR was 4.6% (7/152) while culture proven endometrial TB was 2.6% (4/152). However, histological examination identified only 2/152 (1.3%) endometrial tuberculosis. While all culture proven TB samples were also PCR positive for Mtb, only one histologic proven endometrial TB was culture and PCR positive. All of the four isolates by culture were M. tuberculosis. CONCLUSION: This study has shown that the magnitude of endometrial TB is fairly high in gynecologic patients visiting outpatient departments for various complaints and PCR detects more cases than culture or Histopathology.

How uterine microbiota might be responsible for a receptive, fertile endometrium.

BACKGROUND: Fertility depends on a receptive state of the endometrium, influenced by hormonal and anatomical adaptations, as well as the immune system. Local and systemic immunity is greatly influenced by microbiota. Recent discoveries of 16S rRNA in the endometrium and the ability to detect low-biomass microbiota fueled the notion that the uterus may be indeed a non-sterile compartment. To date, the concept of the 'sterile womb' focuses on in utero effects of microbiota on offspring and neonatal immunity. However, little awareness has been raised regarding the importance of uterine microbiota for endometrial physiology in reproductive health; manifested in fertility and placentation. OBJECTIVE AND RATIONALE: Commensal colonization of the uterus has been widely discussed in the literature. The objective of this review is to outline the possible importance of this uterine colonization for a healthy, fertile uterus. We present the available evidence regarding uterine microbiota, focusing on recent findings based on 16S rRNA, and depict the possible importance of uterine colonization for a receptive endometrium. We highlight a possible role of uterine microbiota for host immunity and tissue adaptation, as well as conferring protection against pathogens. Based on knowledge of the interaction of the mucosal immune cells of the gut with the local microbiome, we want to investigate the potential implications of commensal colonization for uterine health. SEARCH METHODS: PubMed and Google Scholar were searched for articles in English indexed from 1 January 2008 to 1 March 2018 for '16S rRNA', 'uterus' and related search terms to assess available evidence on uterine microbiome analysis. A manual search of the references within the resulting articles was performed. To investigate possible functional contributions of uterine microbiota to health, studies on microbiota of other body sites were additionally assessed. OUTCOMES: Challenging the view of a sterile uterus is in its infancy and, to date, no conclusions on a 'core uterine microbiome' can be drawn. Nevertheless, evidence for certain microbiota and/or associated compounds in the uterus accumulates. The presence of microbiota or their constituent molecules, such as polysaccharide A of the Bacteroides fragilis capsule, go together with healthy physiological function. Lessons learned from the gut microbiome suggest that the microbiota of the uterus may potentially modulate immune cell subsets needed for implantation and have implications for tissue morphology. Microbiota can also be crucial in protection against uterine infections by defending their niche and competing with pathogens. Our review highlights the need for well-designed studies on a 'baseline' microbial state of the uterus representing the optimal starting point for implantation and subsequent placenta formation. WIDER IMPLICATIONS: The complex interplay of processes and cells involved in healthy pregnancy is still poorly understood. The correct receptive endometrial state, including the local immune environment, is crucial not only for fertility but also placenta formation since initiation of placentation highly depends on interaction with immune cells. Implantation failure, recurrent pregnancy loss, and other pathologies of endometrium and placenta, such as pre-eclampsia, represent an increasing societal burden. More robust studies are needed to investigate uterine colonization. Based on current data, future research needs to include the uterine microbiome as a relevant factor in order to understand the players needed for healthy pregnancy.

Correlation between Seropositivity of Chlamydia Trachomatis and Tubal and/or Pelvic Pathology Detected by Diagnostic Laparoscopy in Subfertile Women.

This prospective observational study was carried out in the Infertility Unit, Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from February 2011 to December 2013. Sixty-nine (69) subfertile women who were seropositive for Chlamydia Trachomatis were included in this study. Inclusion criteria was patients with sub-fertility having age between 22 and 40 years, seeking infertility treatment, normal ovarian function, all normozoospermic male partner, duration of infertility ranged from 1.5 to 14 years. Exclusion criteria were patients having sub-fertility with extensive pelvic and/or ovarian surgery, endometriosis, ablation of endometriotic spots, pelvic tuberculosis and history of ectopic pregnancy. Before laparoscopic evaluation, all study women were screened for Chlamydia Trachomatis Specific IgG & IgM antibodies using ELISA in the Microbiology Department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. All the study women had positive results for IgG antibodies. All study women underwent diagnostic laparoscopy. During laparoscopy, we observed the condition of pelvic cavity, uterus, fallopian tubes, ovaries, peritubal adhesions, tubo-ovarian relationship, status of Pouch of Douglas (POD), fimbriae etc. During dye test procedure, dilute methylene blue dye was injected through the cervical canal and the dye spill out was observed to confirm the tubal patency or blockage or pattern of flow of dye. The results of laparoscopic findings demonstrated that mobility of uterus was restricted in 20(29%) cases, adhesion of uterus with peritoneum was in 8(11.6%) cases, uterine fibroid was present in 11(15.9%) cases, hydrosalpinx in right fallopian tubes were in 27(39.1%) cases, in left fallopian tubes were in 32(46.4%) cases and in both fallopian tubes in 16(23.2%) cases, inflamed right fallopian tubes in 32(46.4%) cases, inflamed left fallopian tubes in 36(52.2%) cases and inflamed both fallopian tubes in 26(37.7%) cases, adhesions in pouch of Douglas was in 4(5.8%) cases, collections in pouch of Douglas was in 7(10.1%) cases and obliterations in pouch of Douglas was in 5(7.2%) cases. Results of Dye test during laparoscopy were that right fallopian tube was blocked in 32(46.4%) cases, left fallopian tube was blocked in 32(46.4%) cases and both fallopian tubes were blocked in 21(30.4%) cases. This study shows that by laparoscopy, significant number of cases of tubal and pelvic pathology was diagnosed in the chlamydia trachomatis seropositive subfertile female. This indicates strong correlation between seropositivity of chlamydia trachomatis and/or pelvic pathology detected by diagnostic laparoscopy.

Molecular aspects of uterine diseases in dogs.

Uterine diseases are common in dogs, particularly in countries where elective spaying is not usually performed. The associated clinical illnesses may be of varying degree ranging from merely decreased fertility to a critical pyometra requiring intensive care to survive. The diagnosis of some uterine diseases is generally uncomplicated, such as in a classic pyometra presenting with enlarged, fluid-filled uterus, purulent vaginal discharge and characteristic signs of illness or in other disorders associated with uterine enlargement. However, it can be more puzzling in diseases with normal uterine size and very mild or obscure clinical signs. It is important to recognize the uterine diseases early because of the risk of potentially life-threatening complications such as sepsis developing if treatment is delayed in cases where bacterial infection is present. In breeding bitches, an early diagnosis, that is when the disease has not developed extensively, will increase the possibility of non-surgical treatment options without increased risk and thereby also increasing chances of maintained fertility. Early diagnosis and treatment initiation are thus favourable for complete recovery, also in less severe uterine diseases and those without infection. Molecular markers are molecules in biological samples that can be measured for diagnostic purposes, outcome prediction, and for gaining more information about different physiological and pathological conditions. Examples of commonly evaluated markers include laboratory variables analysed in blood, urine, cytological or tissue biopsy samples. Regarding the genetic pre-disposition for different uterine diseases in dogs, information is lacking. Recently, the global gene expression in uterine tissue in dogs has been investigated more closely, and newly developed technologies provide excellent opportunities for identifying molecular markers worth exploring further. The focus of this review article is to highlight findings on markers relevant for diagnosis, prediction of prognosis and treatment outcome in the most common uterine diseases in dogs.

ENDOMETRIAL POLYPS IN WOMEN OF REPRODUCTIVE AGE: CLINICAL AND PATHOGENE-TIC VARIATIONS.

The aim of the study was to study the relationship between the morphofunctional characteristics of the endometrium, hormonal homeostasis and microbiocenosis of the reproductive system in patients with endometrial polyps. The study involved 130 patients aged 18-35 years: 34 patients with endometrial polyps, 30 patients with micropolyps, 36 patients with endometrial polyps and micropolyps, 30 healthy women of the control group. Hysteroscopy was performed for women who had been suspected for endometrial polyps and who had infertility or repeated recurrent miscarriages. Endometrial samples from healthy women were obtained by aspiration biopsy. The endometrial sections were immunostained with monoclonal antibodies against the specific markers of plasmacytes (CD138), NK cells (CD56, CD16), pan-leukocytes (CD45), macrophages (CD68), cellular marker for proliferation (Ki-67), ER, PR. Bacteriological examination of the endometrium was performed by PCR and by cultivating aerobic and anaerobic microorganisms on special growth media. In all groups of women the content in blood serum for 3-5 day of a menstrual cycle of gonadotropic hormones (FSH, LH) and sex steroid hormones (estradiol, prolactin) was studied, for 21 days of a cycle estimated the content of progesterone. Level of an expression of receptors of progesterone and estrogen estimated in endometrium and at EP, also in І a cycle phase. Highlighted are separate clinical and pathogenetic variations of endometrial polyps: isolated polyps, micropolyps, polyps in conjunction with micropolyps. In the course of study, it was found that progesterone deficiency and local immune imbalance with severe hypofunctional NK cells against viral and fungal infestations result in excessive endometrial cell proliferation and development of an isolated polyp. The case of a polyp merging with micropolyps potentiates an active inflammatory process alongside all of the mechanisms mentioned above. Micropolyps as a macroscopic manifestation of an active inflammatory process in chronic endometritis are characterized by focal infiltrates of leukocytes (CD45), macrophages (CD68), plasmacells (CD138) and NK (CD56) cells, whose activity leads to excess abnormal proliferation of endometrium, even in the absence of hormone receptor disorders.

Endometrial Tuberculosis Simulating an Ovarian Cancer: a case report.

Female genital tuberculosis remains a major health problem in developing countries and is an important cause of infertility. As symptoms, laboratory data and physical findings are non-specific, its diagnosis can be difficult. We describe a case of a 39-year-old woman suffering from peri-umbilical pain and increased abdominal size for one year, anorexia, asthenia, weight loss, occasionally dysuria and dyspareunia, and four months amenorrhea. Laboratory data revealed cancer antigen 125 (CA-125) level of 132.3 U/mL, erythrocyte sedimentation rate of 42 mm/h, and gamma-globulins of 2.66 g/dL. Computed tomography scan showed loculated ascites. It was initially suspected a carcinomatous origin, but ascites evaluation was negative for malignant cells. Magnetic resonance imaging from another hospital showed endometrial heterogeneity. Therefore, an endometrial biopsy was performed demonstrating an inflammatory infiltrate with giant cells of type Langhans and bacteriological culture identified Mycobacterium tuberculosis.

A tuberculose genital feminina continua a representar uma patologia importante nos países em desenvolvimento e constitui uma causa importante de infertilidade. Os seus sintomas, achados laboratoriais e exame físico não são específicos, tornando difícil o seu dia-gnóstico. Descrevemos o caso de uma doente do sexo feminino, de 39 anos, com dor peri-umbilical e aumento do volume abdominal desde há um ano, anorexia, astenia, perda ponderal, ocasionalmente disúria e dispareunia, assim como amenorreia desde há quatro meses. Os dados laboratoriais mostraram valores de 132,3 U/mL do marcador tumoral CA-125, 42 mm/h de velocidade de sedimentação e 2,66 g/dL de gama-globulinas. A tomografia computadorizada mostrou ascite loculada. Inicialmente suspeitou-se de etiologia maligna, mas o exame citológico do líquido ascítico foi negativo para células malignas. Foi efectuada ressonância magnética pélvica, noutra instituição, que revelou heterogeneidade do endométrio. Foi então realizada biópsia endometrial que revelou um infiltrado inflamatório com células gigantes de Langhans e o exame bacteriológico isolou Mycobacterium tuberculosis.

Lichen scrofulosorum and endometrial tuberculosis: a novel association.

BACKGROUND: Lichen scrofulosorum (LS) is a rare tuberculid with an underlying systemic focus of tuberculosis (Tb) detected in majority of cases. The associated Tb foci reported in literature include pulmonary, lymph node, intracranial, abdominal, and cutaneous Tb. We report two women who presented with LS and infertility due to endometrial Tb; an association hitherto undescribed. CASE REPORT: Case 1: A 24-year-old woman presented with asymptomatic grouped papules of LS over the trunk associated with secondary infertility. Endometrial biopsy was suggestive of endometrial Tb, and PCR was positive for M. tuberculosis. The skin lesions resolved after 3 months of anti-tubercular therapy (ATT). Case 2: A 27-year-old woman presented with erythematous, grouped, perifollicular papules over the trunk 5 weeks after starting ATT for endometrial Tb that was diagnosed during work up for primary infertility. A skin biopsy confirmed the diagnosis of LS, and lesions resolved with continuation of ATT for 10 weeks. CONCLUSION: LS can mimic several dermatologic diseases, and a high index of suspicion is required for the diagnosis and initiation of investigations to detect the underlying Tb focus. A good obstetric history in females will aid in early diagnosis and initiation of appropriate therapy.

Preterm labor and neonatal sepsis caused by intrauterine Helicobacter cinaedi infection.

Helicobacter cinaedi is a rare pathogen but known to cause bacteremia, cellulitis and enterocolitis. Recently, cases of involving various organs are increasingly reported such as endocarditis, meningitis, and kidney cyst infection. We report a case of intrauterine H. cinaedi infection leading preterm birth and neonatal sepsis. A 29-year-old pregnant women who was no underlying disease hospitalized due to threatened preterm labor at 22 weeks of gestation. Clinical findings showed uterine tenderness, fever, leukocytosis and elevated C-reactive protein. H. cinaedi was isolated from amniotic fluid obtained by transabdominal amniocentesis. We diagnosed as intrauterine H. cinaedi infection and administered intravenous ampicillin followed by oxytocin to terminate pregnancy. A live 446 g male infant was delivered. The patient was no signs of infection throughout postpartum course and discharged on post-delivery day 5. The neonate was admitted in neonatal intensive care unit and administered ampicillin and amikacin. H. cinaedi was isolated from umbilical cord blood culture. He has no signs of infection on day 5 but died from uncontrollable hyperglycemia and ketoacidosis on 15 days of age. H. cinaedi can cause intrauterine infection during pregnancy and lead preterm labor and neonatal sepsis.

[Hysterectomy for benign pathology: Guidelines for clinical practice]. / Hystérectomie pour pathologie bénigne: recommandations pour la pratique clinique.

OBJECTIVE: The objective of the study was to provide guidelines for clinical practice from the French college of obstetrics and gynecology (CNGOF), based on the best evidence available, concerning hysterectomy for benign pathology. METHODS: Each recommendation for practice was allocated a grade which depends on the level of evidence (guidelines for clinical practice method). RESULTS: Hysterectomy should be performed by a high volume surgeon (>10 procedures of hysterectomy per year) (grade C). Rectal enema stimulant laxatives are not recommended prior to hysterectomy (grade C). It is recommended to carry out vaginal disinfection using povidone iodine solution prior to an hysterectomy (grade B). Antibioprophylaxis is recommended during a hysterectomy, regardless of the surgical route (grade B). The vaginal or the laparoscopic routes are recommended for hysterectomy for benign pathology (grade B), even if the uterus is large and/or the patient is obese (grade C). The choice between these two surgical approaches depends on others parameters, such as the surgeon's experience, the mode of anesthesia and organizational constraints (operative duration and medico economic factors). Hysterectomy by vaginal route is not contraindicated in nulliparous women (grade C) or in women with previous c-section (grade C). No specific technique to achieve hemostasis is recommended with a view to avoid urinary tract injuries (grade C). In the absence of ovarian pathology and personal or family history of breast/ovarian carcinoma, it is recommended to conserve ovaries in pre-menopausal women (grade B). Subtotal hysterectomy is not recommended in order to diminish the risk of per- or postoperative complications (grade B). CONCLUSION: The application of these recommendations should minimize risks associated with hysterectomy.

Intrauterine Tuberculosis Manifesting as Acute Chorioamnionitis: A Case Report and Review of the Literature.

Congenital tuberculosis involving the placenta is an infrequent diagnosis, and the typical features of tuberculous placentitis involve a granulomatous reaction, reflecting a delayed hypersensitivity immune response in the host. However, the first reaction of the placenta to organisms hematogenously transmitted from the maternal circulation typically involves the innate immune response, manifesting as an acute neutrophilic villitis or intervillositis or both. This acute pattern of response to mycobacteria has only been documented rarely. We present a case of acute mycobacterial infection occurring in a preterm female with 28-weeks gestation, who was delivered by cesarean section because of fetal distress and who was subsequently confirmed to have congenital tuberculosis. The placenta showed an acute chorioamnionitis associated with acid-fast bacilli consistent with Mycobacteria tuberculosis. The mother was found to have a necrotizing granulomatous deciduitis, and that was postulated to have resulted in the direct spread of mycobacteria to the amniotic cavity. Thus, our case extends the acute placental response to mycobacteria to include chorioamnionitis. Although extremely rare, mycobacteria should be considered in the differential diagnosis of infectious agents causing acute chorioamnionitis, especially in geographic areas where tuberculosis is more prevalent.

Chlamydia muridarum induction of glandular duct dilation in mice.

Although Chlamydia-induced hydrosalpinx in women and mice has been used as a surrogate marker for tubal infertility, the medical relevance of nontubal pathologies, such as uterine horn dilation, developed in mice following chlamydial infection remains unclear. We now report that the uterine horn dilation correlates with glandular duct dilation detected microscopically following Chlamydia muridarum infection. The dilated glandular ducts pushed the uterine horn lumen to closure or dilation and even broke through the myometrium to develop extrusion outside the uterine horn. The severity scores of uterine horn dilation observed macroscopically correlated well with the number of cross sections of the dilated glandular ducts counted under microscopy. Chlamydial infection was detected in the glandular epithelial cells, potentially leading to inflammation and dilation of the glandular ducts. Direct delivery of C. muridarum into the mouse uterus increased both uterine horn/glandular duct dilation and hydrosalpinx. However, the chlamydial plasmid, which is essential for the induction of hydrosalpinx, was not required for the induction of uterine horn/glandular duct dilation. Screening 12 strains of mice for uterine horn dilation following C. muridarum infection revealed that B10.D2, C57BL/10J, and C57BL/6J mice were most susceptible, followed by BALB/cJ and A/J mice. Deficiency in host genes involved in immune responses failed to significantly alter the C. muridarum induction of uterine horn dilation. Nevertheless, the chlamydial induction of uterine horn/glandular duct dilation may be used to evaluate plasmid-independent pathogenicity of Chlamydia in susceptible mice.
