    Medullary thyroid carcinoma (MTC) may rarely present with paraneoplastic syndromes. Among the most frequent ones are the appearance of diarrhea and ectopic Cushing syndrome (ECS). The ECS in the context of MTC is usually present in patients with distant metastatic disease. The use of drugs such as ketoconazole, metyrapone, somatostatin analogs and etomidate have been ineffective alternatives to control hypercortisolism in these patients. Bilateral adrenalectomy is often required to manage this situation. Recently, the use of tyrosine kinase inhibitors has been shown to be a useful tool to achieve eucortisolism in patients with metastatic MTC and ECS. We present a patient with sporadic advanced persistent and progressive MTC with lymph node and liver metastases, which after 16 years of followup developed an ECS. After one month of 300 mg/day vandetanib treatment, a biochemical and clinical response of the ECS was achieved but it did not result in significant reduction of tumor burden. However the patient reached criteria for stable disease according to response evaluation criteria in solid tumors (RECIST 1.1) after 8 months of follow-up. (author)

    This study reports on genetic susceptibility to ectopic calcification in the LG/J and SM/J advanced intercross mice. Using 347 mice in 98 full-sibships, destabilization of medial meniscus (DMM) was performed to induce joint injury. We found that joint destabilization instigated ectopic calcifications as detected and quantified by micro-CT. We performed quantitative trait locus (QTL) analysis to map ectopic calcification phenotypes to discrete genomic locations. To validate the functional significance of the selected QTL candidate genes, we compared mRNA expression between parental LG/J and SM/J inbred strains. Overall, we detected 20 QTLs affecting synovial and meniscus calcification phenotypes with 11 QTLs linked to synovial calcification. Functional and bioinformatic analyses of single nucleotide polymorphism (SNP) identified functional classifications relevant to angiogenesis (Myo1e, Kif26b, Nprl3, Stab2, Fam105b), bone metabolism/calcification (Tle3, Tgfb2, Lipc, Nfe2l1, Ank, Fam105b), arthritis (Stab2, Tbx21, Map4k4, Hoxb9, Larp6, Col1a2, Adam10, Timp3, Nfe2l1, Trpm3), and ankylosing-spondylitis (Ank, Pon1, Il1r2, Tbkbp1) indicating that ectopic calcification involves multiple mechanisms. Furthermore, the expression of 11 out of 78 candidate genes was significantly different between LG/J and SM/J. Correlation analysis showed that Aff3, Fam81a, Syn3, and Ank were correlated with synovial calcification. Taken together, our findings of multiple genetic loci suggest the involvement of multiple genes contributing to ectopic calcification.

    Results: Lower abdominal pain was most common presenting symptom of ectopic pregnancy in 96% cases. The classical triad of symptoms (amenorrhea, abdominal pain and vaginal bleeding was present in only 28% cases. PID contributed 24% cases and previous abortion contributed 28% cases indicating these two as the common risk factors. Ampulla was the commonest site for ectopic pregnancy, in 52% cases. Salpingostomy performed mainly at this site. In 6% cases ectopic pregnancy in infundibulum were treated with fimbrial expression and fimbriectomy. 22% patients were managed medically (methotraxte. These were the cases having unruptured ectopic pregnancy and ectopic mass <4 cm. Laparoscopy was done in 34% cases, in 2 cases it was converted to laparotomy. While open laparotomy was done in 40% cases. Conclusions: Ectopic pregnancy is a treatable problem. Ultrasonography plays central role in the diagnosis and management. Mode of therapy is determined by a combination of clinical symptoms, sonography findings and serum b-HCG values. Surgical management is still a cornerstone of management of ectopic pregnancy. But now scope of medical and laparoscopic management is also there. In recent years laparotomy has been replaced by laparoscopic surgery which is more conservative, minimally invasive and less time consuming which leads to quick recovery.

    Calcium deposition can be observed in many tissues in addition to bones and teeth which physiologically calcify. This unphysiological calcification can damage several organs. It has been shown that vascular calcification which is a risk factor for cardiovascular events develops through similar mechanisms to physiological calcification. Further studies to clarify detailed mechanisms of calcification are necessary to develop measures that inhibit unphysiological ectopic calcification without affecting physiological calcification in bones and teeth.

    Full Text Available An ectopic pregnancy is one in which fertilized ovum is implanted at the site other than normal uterine cavity.[1] Incidence of ectopic pregnancy is 1:160 deliveries.[2] Clinical presentation is variable from acute to chronic type. Due to its varied clinical presentation ectopic pregnancy poses great diagnostic difficulty both to obstetrician, physician and surgeons.[3] OBJECTIVE: To find out incidence in our study population and to evaluate symptomatically and clinical presentation in these patients. MATERIALS AND METHODS: Retrospective study of 34 ectopic pregnancies admitted and treated in Medical College hospital, Ujjain from 2010 to 2015 are included in the study. RESULTS: The incidence of ectopic pregnancy is more between the age group of 21-30years (73.52% and in Multigravida 64.71%. Infertility and previous tubal surgery are the high risk factors for tubal pregnancy. Pain in abdomen was present in all 34 cases, amenorrhea in 97.05% and bleeding per vagina in 76.47% cases. Syncopal attacks, vomiting were detected in 14.70% cases. Acute ectopic pregnancy was detected in 14.71% and chronic in 85.29% cases. 82.35% cases presented with adnexal mass, 79.41% with cervical motion tenderness, 50% with pallor, 32.35% with abdominal lump and tenderness and 11.76% with fullness in POD. CONCLUSION: Ectopic pregnancy is leading cause of maternal mortality in first trimester. In spite of advanced diagnostic techniques. It poses great diagnostic difficulties due to varied signs and symptoms. Previous tubal surgery pelvic inflammatory disease and infertility are the risk factors of tubal pregnancy.

    This review summarizes the current knowledge on the structure, function, assembly, and biomedical applications of the family of adhesive fimbrial organelles assembled on the surface of Gram-negative pathogens via the FGL chaperone/usher pathway. Recent studies revealed the unique structural and functional properties of these organelles, distinguishing them from a related family, FGS chaperone-assembled adhesive pili. The FGL chaperone-assembled organelles consist of linear polymers of one or two types of protein subunits, each possessing one or two independent adhesive sites specific to different host cell receptors. This structural organization enables these fimbrial organelles to function as polyadhesins. Fimbrial polyadhesins may ensure polyvalent fastening of bacteria to the host cells, aggregating their receptors and triggering subversive signals that allow pathogens to evade immune defense. The FGL chaperone-assembled fimbrial polyadhesins are attractive targets for vaccine and drug design.

    Full Text Available Background: Porphyromonas gulae are black-pigmented anaerobic bacteria isolated from the gingival sulcus of various animal hosts and are distinct from Porphyromonas gingivalis originating in humans. We previously reported the antigenic similarities of 41-kDa fimbriae between P. gulae ATCC 51700 and P. gingivalis ATCC 33277. In this study, to clarify the presence of another type of fimbriae of P. gulae, we have purified and characterized the secondary fimbrial protein from P. gulae ATCC 51700. Methods: The secondary fimbrial protein was purified from P. gulae ATCC 51700 using an immunoaffinity column coupling with antibodies against the 41-kDa fimbrial protein. The expression of fimbriae on the cell surface of P. gulae ATCC 51700 was investigated by transmission electron microscopy. The N-terminal amino acid sequence was determined by an amino acid sequencer system. Results: The molecular mass of this protein was approximately 53-kDa, as estimated by SDS-PAGE. The polyclonal antibodies against the 53-kDa protein did not react with the 41-kDa fimbrial protein of P. gulae ATCC 51700. Immunogold electron microscopy revealed that anti-53-kDa fimbrial serum bound to fimbria on the cell surface of P. gulae ATCC 51700. The amino acid sequence of the N-terminal 15 residues of the 53-kDa fimbrial protein showed only 1 of 15 residues identical to the 41-kDa fimbrial protein. Conclusion: The 53-kDa fimbriae are different in molecular weight and antigenicity from the 41-kDa fimbrial protein of P. gulae ATCC 51700. These results clearly suggest that the 41-kDa and the 53-kDa fimbriae are distinct types of fimbriae expressed simultaneously by this organism.

    Full Text Available Introduction. Ectopic lymphoid neogenesis and the presence of IgG4-positive plasmacytes have been confirmed in chronic inflammatory sclerosing diseases. This study aims to investigate hip synovial tissues of ankylosing spondylitis (AS patients for IgG4-positive plasma cells and ectopic lymphoid tissues with germinal centers (GCs. Methods. Synovial samples were collected from 7 AS patients who received total hip replacement and were evaluated using immunohistochemistry for the presence of CD20+ B-cells, CD3+ T-cells, CD21+ follicular dendritic cells (FDC, and CD38+ plasma cells. Furthermore, immunoglobulin G (IgG and IgG4, IgA, IgM, and complement components C3d and C4d in synovia were evaluated. Both synovial CD21+ FDCs and IgG4-producing plasmacytes were analyzed. Results. All seven patients had severe fibrosis. Massive infiltrations of lymphocytes were found in 5 out of 7 patients’ synovia. Ectopic lymphoid tissues with CD21+ FDC networks and IgG4-positive plasma cells were observed coincidentally in two patients’ synovia. Conclusion. The pathophysiological mechanism of AS patients’ hip damage might be related to the coincidental presence of ectopic lymphoid tissue with FDCs network and IgG4-positive plasma cells identified here for the first time in AS patients’ inflamed synovial tissue.

  17. Bordetella pertussis isolates in Finland: Serotype and fimbrial expression

    Full Text Available Abstract Background Bordetella pertussis causes whooping cough or pertussis in humans. It produces several virulence factors, of which the fimbriae are considered adhesins and elicit immune responses in the host. B. pertussis has three distinct serotypes Fim2, Fim3 or Fim2,3. Generally, B. pertussis Fim2 strains predominate in unvaccinated populations, whereas Fim3 strains are often isolated in vaccinated populations. In Finland, pertussis vaccination was introduced in 1952. The whole-cell vaccine contained two strains, 18530 (Fim3 since 1962 and strain 1772 (Fim2,3 added in 1976. After that the vaccine has remained the same until 2005 when the whole-cell vaccine was replaced by the acellular vaccine containing pertussis toxin and filamentous hemagglutinin. Our aims were to study serotypes of Finnish B. pertussis isolates from 1974 to 2006 in a population with > 90% vaccination coverage and fimbrial expression of the isolates during infection. Serotyping was done by agglutination and serotype-specific antibody responses were determined by blocking ELISA. Results Altogether, 1,109 isolates were serotyped. Before 1976, serotype distributions of Fim2, Fim3 and Fim2,3 were 67%, 19% and 10%, respectively. From 1976 to 1998, 94% of the isolates were Fim2 serotype. Since 1999, the frequency of Fim3 strains started to increase and reached 83% during a nationwide epidemic in 2003. A significant increase in level of serum IgG antibodies against purified fimbriae was observed between paired sera of 37 patients. The patients infected by Fim3 strains had antibodies which blocked the binding of monoclonal antibodies to Fim3 but not to Fim2. Moreover, about one third of the Fim2 strain infected patients developed antibodies capable of blocking of binding of both anti-Fim2 and Fim3 monoclonal antibodies. Conclusion Despite extensive vaccinations in Finland, B. pertussis Fim2 strains were the most common serotype. Emergence of Fim3 strains started in 1999 and

    BACKGROUND An ectopic pregnancy is a pregnancy which occurs outside of the uterine cavity, and over 98% implant in the Fallopian tube. Tubal ectopic pregnancy remains the most common cause of maternal mortality in the first trimester of pregnancy. The epidemiological risk factors for tubal ectopic pregnancy are well established and include: tubal damage as a result of surgery or infection (particularly Chlamydia trachomatis), smoking and in vitro fertilization. This review appraises the data to date researching the aetiology of tubal ectopic pregnancy. METHODS Scientific literature was searched for studies investigating the underlying aetiology of tubal ectopic pregnancy. RESULTS Existing data addressing the underlying cause of tubal ectopic pregnancy are mostly descriptive. There are currently few good animal models of tubal ectopic pregnancy. There are limited data explaining the link between risk factors and tubal implantation. CONCLUSIONS Current evidence supports the hypothesis that tubal ectopic pregnancy is caused by a combination of retention of the embryo within the Fallopian tube due to impaired embryo-tubal transport and alterations in the tubal environment allowing early implantation to occur. Future studies are needed that address the functional consequences of infection and smoking on Fallopian tube physiology. A greater understanding of the aetiology of tubal ectopic pregnancy is critical for the development of improved preventative measures, the advancement of diagnostic screening methods and the development of novel treatments.

    Scar ectopic pregnancy is the rarest form of ectopic pregnancy and has been increasingly diagnosed all over the world. This is a life-threatening form of abnormal implantation of embryo within the myometrium and fibrous tissues in a previous scar on the uterus, especially following caesarean section. With the increasing rate of caesarean section, there is a substantial increase in this condition with better understanding of this disease. The early and accurate diagnosis with timely management can prevent pregnancy complications such as haemorrhage, uterine rupture and can preserve fertility.

    Full Text Available Hidradenoma papilliferum is a rare tumor that occurs almost exclusively in females on the anogenital area. Rare cases of ectopic (nongenital hidradenoma papilliferum have been described. The lesions usually present as an asymptomatic slow-growing, red, firm, mobile, well-delimitated nodule that grows for a long time before resection. We describe a case of an 26-year-old man that presented with an enlarging nodule on his right eyelid. The histological findings revealed a hidradenoma papilliferum. So far, among the very few reports of ectopic hidradenoma papilliferum, only a very small number were localized to the eyelid.

    The fimbriae of Bordetella pertussis are required for colonization of the human respiratory tract. Two serologically distinct fimbrial subunits, Fim2 and Fim3, considered important vaccine components for many years, are included in the Sanofi Pasteur 5-component acellular pertussis vaccine, and the World Health Organization recommends the inclusion of strains expressing both fimbrial serotypes in whole-cell pertussis vaccines. Each of the fimbrial major subunit genes, fim2, fim3, and fimX, has a promoter poly(C) tract upstream of its -10 box. Such monotonic DNA elements are susceptible to changes in length via slipped-strand mispairing in vitro and in vivo, which potentially causes on/off switching of genes at every cell division. Here, we have described intra-culture variability in poly(C) tract lengths and the resulting fimbrial phenotypes in 22 recent UK B. pertussis isolates. Owing to the highly plastic nature of fimbrial promoters, we used the same cultures for both genome sequencing and flow cytometry. Individual cultures of B. pertussis contained multiple fimbrial serotypes and multiple different fimbrial promoter poly(C) tract lengths, which supports earlier serological evidence that B. pertussis expresses both serotypes during infection.

    Introduction Primary ectopic craniopharyngiomas have only rarely been reported. Craniopharyngiomas involve usually the sellar and suprasellar region, but can be originated from cell remnants of the obliterated craniopharyngeal duct or metaplastic change of andenohypophyseal cells. We present the first case of a primary ectopic frontotemporal craniopharyngioma. Presentation of case A 35-year old woman presented with a one-year history of headache and diplopia. MRI showed a large frontotemporal cystic lesion. Tumor resection was performed with a keyhole endoscopic frontal lateral approach. The pathological features showed an adamantinomatous craniopharyngioma with a cholesterol granuloma reaction. Discussion There have been reported different localizations for primary ectopic craniopharyngioma. Our case presented a lobulated frontotemporal cystic mass formed by a dense eosinophilic proteinaceous material dystrophic calcifications and cholesterol crystals, with epithelial remnants. No tumor regrowth was observed in the magnetic resonance image 27 months postoperatively. Conclusion Primary ectopic craniopharyngioma is a rare entity with a pathogenesis that remains uncertain. This is an unusual anatomic location associated with unique clinical findings. PMID:25725331

    Pasteurella multocida serogroup B:2, a causative agent of haemorrhagic secpticaemia (HS) in cattle and buffalo especially in tropical regions of Asia and African countries, is known to possess a type IV fimbriae (pili) as one of the virulent factors. In the present study, ptfA gene encoding for type IV fimbrial subunit of P. multocida serogroup B:2 (strain p52), an Indian HS vaccine strain, has been cloned and over-expressed in recombinant Escherichia coli. The recombinant type IV fimbrial subunit protein (∼31 kDa) including N-terminus histidine tag was purified under denaturing condition and confirmed by western blotting. A homology model of HS causing P. multocida serogroup B:2 fimbrial subunit has also been discussed. The study indicated the potential possibilities to use the recombinant fimbrial protein in developing HS subunit vaccine along with suitable adjuvant.

    The relationship between K-agglutination antibody titres and protection against experimental challenge with Dichelobacter nodosus, the effect of increasing the number of D. nodosus fimbrial antigens, and the importance of the nature of additional antigens in multivalent vaccines on antibody response and protection against experimental challenge with D. nodosus were examined in Merino sheep. A total of 204 Merino sheep were allocated to one of 12 groups, and vaccinated with preparations containing a variable number of rDNA D. nodosus fimbrial antigens. The most complex vaccine contained ten fimbrial antigens from all major D. nodosus serogroups, while the least complex contained a single fimbrial antigen. In addition to D. nodosus fimbrial antigens, other bacterial rDNA fimbrial antigens (Moraxella bovis Da12d and Escherichia coli K99), and bovine serum albumin (BSA) were used in some vaccines. Antibody titres to fimbrial antigens and BSA were measured by agglutination and ELISA tests, respectively. Antibody titres were determined on five occasions (Weeks 0, 3, 6, 8, and 11 after primary vaccination). All sheep were exposed to an experimental challenge with virulent isolates of D. nodosus from either serogroup A or B, 8 weeks after primary vaccination. For D. nodosus K-agglutinating antibody titres, a strong negative correlation between antibody titre and footrot lesion score was observed. This relationship was influenced by the virulence of the challenge strain. Increasing the number of fimbrial antigens in experimental rDNA D. nodosus fimbrial vaccines resulted in a linear decrease in K-agglutinating antibody titres to individual D. nodosus serogroups. Similarly, a linear decrease in protection to challenge with homologous serogroups was observed as the number of D. nodosus fimbrial antigens represented in the vaccine increased. The reduction in antibody titres in multicomponent vaccines is thought to be due to antigenic competition. The level of competition

    Full Text Available INTRODUCTION Endogenous Cushing's syndrome is a clinical state resulting from prolonged, inappropriate exposure to excessive endogenous secretion of Cortisol and hence excess circulating free cortisol, characterized by loss of the normal feedback mechanisms of the hypothalamo-pituitary-adrenal axis and the normal circadian rhythm of cortisol secretion [2]. The etiology of Cushing's syndrome may be excessive ACTH secretion from the pituitary gland, ectopic ACTH secretion by nonpituitary tumor, or excessive autonomous secretion of cortisol from a hyperfunctioning adrenal adenoma or carcinoma. Other than this broad ACTH-dependent and ACTH-independent categories, the syndrome may be caused by ectopic CRH secretion, PPNAD, MAH, ectopic action of GIP or catecholamines, and other adrenel-dependent processes associated with adrenocortical hyperfunction. CASE REPORT A 31 year-old men with b-month history of hyperpigmentation, weight gain and proximal myopathy was refereed to Institute of Endocrinology for evaluation of hypercortisolism. At admission, patient had classic cushingoid habit with plethoric face, dermal and muscle atrophy, abdominal strie rubrae and centripetal obesity. The standard laboratory data showed hyperglycaemia and hypokaliemia with high potassium excretion level. The circadian rhythm of cortisol secretion was blunted, with moderately elevated ACTH level, and without cortisol suppression after low-dose and high-dose dexamethason suppression test. Urinary 5HIAA was elevated. Abdominal and sellar region magnetic resonance imaging was negative. CRH stimulation resulted in ACTH increase of 87% of basal, but without significant increase of cortisol level, only 7%. Thoracal CT scan revealed 14 mm mass in right apical pulmonary segment. A wedge resection of anterior segment of right upper lobe was performed. Microscopic evaluation showed tumor tissue consisting of solid areas of uniform, oval cells with eosinophilic cytoplasm and centrally

    Urinary tract infections (UTIs) are one of the most common bacterial infections in humans, causing cystitis, pyelonephritis, and renal failure. Uropathogenic Escherichia coli (UPEC) is the leading cause of UTIs. Accurate and rapid discrimination of UPEC lineages is useful for epidemiological surveillance. Fimbriae are necessary for the adherence of UPEC strains to host uroepithelia, and seem to be abundant and diverse in UPEC strains. By analyzing all the possible fimbrial operons in UPEC strains, we found that closely related strains had similar types of chaperone-usher fimbriae, and the diversity of fimbrial genes was higher than that of multilocus sequence typing (MLST) genes. A typing assay based on the polymorphism of four gene sequences (three fimbrial genes and one housekeeping gene) and the diversity of fimbriae present was developed. By comparison with the MLST, whole-genome sequence (WGS) and fumC/fimH typing methods, this was shown to be accurate and have high resolution, and it was also relatively inexpensive and easy to perform. The assay can supply more discriminatory information for UPEC lineages, and have the potential to be applied in epidemiological surveillance of UPEC isolates.

    To describe a technique for the laparoscopic management of a cornual ectopic pregnancy. Step-by-step explanation of the procedure using video (Canadian Task Force classification III). Cornual pregnancy is a rare form of ectopic pregnancy, accounting for up to 2% to 4% of all ectopic pregnancies, with a mortality range of 2.0% to 2.5%, and this accounts for 20% of all deaths caused by ectopic pregnancies. Both medical and surgical treatments have been reported. Although laparotomy hysterectomy and cornuectomy used to be the preferred surgical approaches, more cornual ectopic pregnancies are being managed with the laparoscopic approach through cornuostomy or cornuectomy in recent years. The main concern with surgical treatment is hemorrhage and the need for cornual reconstruction, which necessitate advanced laparoscopic skills and technique. In this video, we describe our technique for the treatment of a cornual ectopic pregnancy. We present the case of a 21-year-old G3P2002 (gravida 3 para 2002) with the finding of a right live cornual ectopic pregnancy with gestational age of 6 weeks on pelvic ultrasound along with an elevated human chorionic gonadotropin level at 7,192 and right pelvic pain. After counseling regarding treatment options, the patient agreed with proceeding with surgery and underwent a laparoscopic right cornuectomy. Her surgery was uneventful, and she was discharged home a few hours after surgery. She was completely recovered at her postoperative follow-up visit. Her serial serum human chorionic gonadotropin levels were followed until complete resolution a few weeks later. Laparoscopic cornuectomy is a safe and effective procedure for the management of cornual ectopic pregnancy. The use of hemostatic agents and suturing can help prevent hemorrhage and allows a safe removal of the ectopic pregnancy and repair of the uterine defect created. Copyright © 2016 AAGL.

    11 per 1000 pregnancies are ectopic (NICE Guidelines, 2012) with 95 % of ectopic pregnancies being tubal in origin, and 80 % of these occurring within the ampulla (The Ectopic Pregnancy Trust). 5% therefore are non-tubal. In this review we aim to collate literature relevant to non-tubal ectopic pregnancy. Literature regarding cornual, ovarian, abdominal, interstitial, cervical and Caesarean scar ectopic pregnancy was reviewed using EMBASE and Medline databases. Non-tubal ectopic pregnancies are often overlooked, diagnosed late and are associated with higher maternal morbidity and mortality. Ultrasound remains the mainstay of diagnosis in corroboration with clinical features. Management may include medical treatment with methotrexate, surgery or expectancy. There is also an increasing interest in the use of minimally invasive radiological approaches. Non-tubal ectopic pregnancy is a rare but potentially life-threatening and often misdiagnosed condition. This is particularly pertinent for Caesarean scar ectopic pregnancies, the prevalence of which is increasing due to the rising proportion of women having Caesarean sections (Litwicka and Greco, 2011). Practitioners should be aware of non-tubal pregnancies to aid more efficient diagnosis, optimise management and increase patient safety.

  11. Genetic exchange of fimbrial alleles exemplifies the adaptive virulence strategy of Porphyromonas gingivalis.

    Directory of Open Access Journals (Sweden)

    Jennifer E Kerr

    Full Text Available Porphyromonas gingivalis is a gram-negative anaerobic bacterium, a member of the human oral microbiome, and a proposed "keystone" pathogen in the development of chronic periodontitis, an inflammatory disease of the gingiva. P. gingivalis is a genetically diverse species, and is able to exchange chromosomal DNA between strains by natural competence and conjugation. In this study, we investigate the role of horizontal DNA transfer as an adaptive process to modify behavior, using the major fimbriae as our model system, due to their critical role in mediating interactions with the host environment. We show that P. gingivalis is able to exchange fimbrial allele types I and IV into four distinct strain backgrounds via natural competence. In all recombinants, we detected a complete exchange of the entire fimA allele, and the rate of exchange varies between the different strain backgrounds. In addition, gene exchange within other regions of the fimbrial genetic locus was identified. To measure the biological implications of these allele swaps we compared three genotypes of fimA in an isogenic background, strain ATCC 33277. We demonstrate that exchange of fimbrial allele type results in profound phenotypic changes, including the quantity of fimbriae elaborated, membrane blebbing, auto-aggregation and other virulence-associated phenotypes. Replacement of the type I allele with either the type III or IV allele resulted in increased invasion of gingival fibroblast cells relative to the isogenic parent strain. While genetic variability is known to impact host-microbiome interactions, this is the first study to quantitatively assess the adaptive effect of exchanging genes within the pan genome cloud. This is significant as it presents a potential mechanism by which opportunistic pathogens may acquire the traits necessary to modify host-microbial interactions.

    Ectopic pregnancy is a high-risk condition that occurs in 2% of reported pregnancies. This percentage is fivefold higher than that registered in the 1970s. Since 1970 there has been a two-fold increase in the ratio of ectopic pregnancies to all reported pregnancies in Hungary and in 2012 7.4 ectopic pregnancies per thousand registered pregnancies were reported. Recently, the majority (80%) of cases can be diagnosed in early stage, and the related mortality objectively decreased in the past few decades to 3.8/10,000 ectopic pregnancies. If a woman with positive pregnancy test has abdominal pain and/or vaginal bleeding the physician should perform a work-up to safely exclude the possibility of ectopic pregnancy. The basis of diagnosis is ultrasonography, especially vaginal ultrasound examination and measurement of the β-subunit of human chorionic gonadotropin. The ultrasound diagnosis is based on the visualization of an ectopic mass rather than the inability to visualize an intrauterine pregnancy. In some questionable cases the diagnostic uterine curettage or laparoscopy may be useful. The actuality of this topic is justified by practical difficulties in obtaining correct diagnosis, especially in the early gestational time.

    Ectopic pregnancy remains a leading cause of maternal mortality and accounts for a sizeable proportion of infertility and ectopic recurrence. The possibility that a woman is experiencing an ectopic pregnancy must be considered when evaluating a woman, especially a sterilized woman, who has a possible pregnancy, amenorrhea, abdominal pain, or abnormal bleeding; studies have found that one in six pregnancies occurring after tubal sterilization are ectopic. The authors present a clinical study of 82 cases of ectopic pregnancy admitted to the department of Obstetrics and Gynecology of Mahatma Gandhi Institute of Medical Sciences, Sevagram. Cases of ectopic pregnancy represent 0.99% of total obstetric admissions, of whom 69.51% were diagnosed as such on admission. 40.24% of the women were older than 30 years, while 34.14% were elderly beyond third parity. 70.73% of the women presented before missing their second period. Patients presented with multiple complaints, but the most common was abdominal pain reported by 61.70%. 78.04% were admitted with an acute abdomen, but shock was present in only 7.14% of cases. The main surgical treatment modality was salpingectomy among 59.75%. There was no maternal mortality through postoperative morbidity in the form of paralytic ileus, although fever did occur in some women.

    Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

    Non-fimbrial adhesins, such as Yersinia YadA, Moraxella UspA1 and A2, Haemophilus Hia and Hsf, or Bartonella BadA represent an important class of molecules by which pathogenic proteobacteria adhere to their hosts. They form trimeric surface structures with a head-stalk-anchor architecture. Whereas head and stalk domains are diverse and appear (frequently repetitively) in different combinations, the anchor domains are homologous and display the properties of autotransporters. We have built a molecular model for the prototypical non-fimbrial adhesin, YadA, by combining the crystal structure of the head (PDB:1P9H) with theoretical models for the stalk and the anchor. The head domain is a single-stranded, left-handed beta-helix, connected to the stalk by a conserved trimerization element (the neck). The stalk consists of a right-handed coiled coil, containing ten 15-residue repeats with a C-terminal stutter (insertion of four residues). The stalk continues into the conserved anchor domain, which is formed by four heptads of a left-handed coiled coil, followed by four transmembrane beta-strands. Our model of the YadA coiled coil, generated with the program BeammotifCC, combines these periodicities into a structure that starts with a pronounced right-handed supercoil and ends with a canonical, left-handed conformation. The last two heptads of the coiled coil are located within a 12-stranded beta-barrel, formed by trimerization of the four transmembrane beta-strands in each monomer. We propose that this pore assembles in the outer membrane to form the opening through which the monomer chains exit the cell. After export is completed, the fiber folds and the pore is occluded by the coiled coil. Our model explains how these proteins can act as autotransporters in the absence of any homology to classical, single-chain autotransporters.

  18. Tobacco upregulates P. gingivalis fimbrial proteins which induce TLR2 hyposensitivity.

    Directory of Open Access Journals (Sweden)

    Juhi Bagaitkar

    Full Text Available BACKGROUND: Tobacco smokers are more susceptible to periodontitis than non-smokers but exhibit reduced signs of clinical inflammation. The underlying mechanisms are unknown. We have previously shown that cigarette smoke extract (CSE represents an environmental stress to which P. gingivalis adapts by altering the expression of several virulence factors - including major and minor fimbrial antigens (FimA and Mfa1, respectively and capsule - concomitant with a reduced pro-inflammatory potential of intact P. gingivalis. METHODOLOGY/PRINCIPAL FINDINGS: We hypothesized that CSE-regulation of capsule and fimbrial genes is reflected at the ultrastructural and functional levels, alters the nature of host-pathogen interactions, and contributes to the reduced pro- inflammatory potential of smoke exposed P. gingivalis. CSE induced ultrastructural alterations were determined by electron microscopy, confirmed by Western blot and physiological consequences studied in open-flow biofilms. Inflammatory profiling of specific CSE-dysregulated proteins, rFimA and rMfa1, was determined by quantifying cytokine induction in primary human innate and OBA-9 cells. CSE up-regulates P. gingivalis FimA at the protein level, suppresses the production of capsular polysaccharides at the ultrastructural level, and creates conditions that promote biofilm formation. We further show that while FimA is recognized by TLR2/6, it has only minimal inflammatory activity in several cell types. Furthermore, FimA stimulation chronically abrogates the pro-inflammatory response to subsequent TLR2 stimulation by other TLR-2-specific agonists (Pam3CSK4, FSL, Mfa1 in an IkappaBalpha- and IRAK-1-dependent manner. CONCLUSIONS/SIGNIFICANCE: These studies provide some of the first information to explain, mechanistically, how tobacco smoke changes the P. gingivalis phenotype in a manner likely to promote P. gingivalis colonization and infection while simultaneously reducing the host response to this

    Among the rare anomalies of the breast development, polythelia is the most common, between 1% and 5% of women and men present supernumerary nipples. Polymastia, usually presenting as ectopic breast tissue without areola-nipple complex, is seen mostly along the milk line, extending from the axilla to the pubic region. Ectopic breast tissue is functionally analogous to mammary gland and it is subjected to the same alterations and diseases, whether benign or malignant, that affect normal breast tissue. We report the case of a 21 years-old female evaluated by the medical staff after founding a solid nodular mass by suspect axillary lymphadenopathy. Differential diagnosis with lymphoma is the major problem in these cases. The mass was removed and the intraoperative histological examination showed fibroadenoma in axillary supernumerary breast. Presence of ectopic breast tissue is a rare condition; development of benign mass or malignant degeneration is possible, but it is very unusual. In case of polymastia diagnosis is simple; in case of isolated nodule, without local inflammation or infection, there are greater difficulties. Ultrasonography is diagnostic in case of breast fibroadenoma, but it might be inadequate in ectopic localizations owing to the shortage of mammary tissue around the mass. Preoperative diagnosis is important to plan an adequate surgical treatment; lumpectomy is indicated in case of benign tissue; in case of malignancy, therapy is based on the standard treatment used for breast cancer (surgery, chemotherapy and radiation therapy).

    The aim of this study was to determine the risk factors of ectopic pregnancy in cases presented to the Woman's Health Hospital (WHH) in Assuit University, and to perform clinical audit on strategies for management of ectopic pregnancy in the WHH. This descriptive hospital based study was conducted at the Woman's Health Hospital (WHH) of Assuit University (Egypt). There were 210 patients who were admitted to the WHH with the diagnosis of ectopic pregnancy in the period between February 1, 2015 through the end of October 2015. Data were analyzed by SPSS version 21, using descriptive statistics, Mann-Whitney U test, and Chi square. Ectopic pregnancy affects woman in the reproductive age. There are many risk factors that increase the chance of its occurrence; however, it may also occur in the absence of any risk factors (14.0%). Internal VD (72.5%) is the most frequent risk factor; other risk factors include history of abortion, previous CS, ovulation induction, history of infertility, or previous history of EP. Clinical audit is an important item of any adequate health care. As regards to the clinical audit of EP management, we are not adhering to the guidelines.

  5. Mechanisms of Ectopic Gene Conversion

    Directory of Open Access Journals (Sweden)

    P.J. Hastings

    2010-11-01

    Full Text Available Gene conversion (conversion, the unidirectional transfer of DNA sequence information, occurs as a byproduct of recombinational repair of broken or damaged DNA molecules. Whereas excision repair processes replace damaged DNA by copying the complementary sequence from the undamaged strand of duplex DNA, recombinational mechanisms copy similar sequence, usually in another molecule, to replace the damaged sequence. In mitotic cells the other molecule is usually a sister chromatid, and the repair does not lead to genetic change. Less often a homologous chromosome or homologous sequence in an ectopic position is used. Conversion results from repair in two ways. First, if there was a double-strand gap at the site of a break, homologous sequence will be used as the template for synthesis to fill the gap, thus transferring sequence information in both strands. Second, recombinational repair uses complementary base pairing, and the heteroduplex molecule so formed is a source of conversion, both as heteroduplex and when donor (undamaged template information is retained after correction of mismatched bases in heteroduplex. There are mechanisms that favour the use of sister molecules that must fail before ectopic homology can be used. Meiotic recombination events lead to the formation of crossovers required in meiosis for orderly segregation of pairs of homologous chromosomes. These events result from recombinational repair of programmed double-strand breaks, but in contrast with mitotic recombination, meiotic recombinational events occur predominantly between homologous chromosomes, so that transfer of sequence differences by conversion is very frequent. Transient recombination events that do not form crossovers form both between homologous chromosomes and between regions of ectopic homology, and leave their mark in the occurrence of frequent non-crossover conversion, including ectopic conversion.

    Ectopic pregnancies account for 1.5% to 2% of all pregnancy in the United States. Of these, approximately 10% implant in nontubal locations, including the abdominal cavity, cervix, ovary, interstitial portion of the fallopian tube, broad ligament, the uterine cornua, or within a cesarean section scar. Because these pregnancies tend to present later than typical tubal pregnancies, they have been associated with greater maternal morbidity and mortality. Advances in ultrasound technology have allowed for earlier diagnosis of nontubal ectopic pregnancies, which in turn has led to the development of novel minimally invasive techniques to manage them. One of these methods involves the local injection of 1 of several agents directly into the ectopic pregnancy. In this article we provide a guide to this technique of local injection, including an overview of the potential agents that can be used, and review the diagnostic and specific ultrasound criteria, other possible treatment options, and overall outcomes for nontubal ectopic pregnancies.

    To test the possibility of producing the novel vaccine in plants against diarrhea normally found in neonatal and newly weaned piglets, the faeG gene, encoding a major F4ac fimbrial subunit protein, was introduced into the tobacco chloroplast genome. After two rounds of selection under spectinomycin, we obtained the transgenic plants nearly homoplasmic. RNA gel blot analysis indicated that faeG and the antibiotic selective gene aminoglycoside 3' adenylyltransferase (aadA) were highly transcribed as a dicistron, while the translational level of recombinant FaeG in transplastomic tobacco was about 0.15% of total soluble protein. The immunogenicity of recombinant FaeG produced in tobacco chloroplasts was confirmed by the observation that FaeG-specific antibodies were elicited in mice immunized with total soluble protein of transgenic plants, as well as the result that mouse sera stimulated by chloroplast-derived recombinant FaeG could neutralize F4ac enterotoxigenic Escherichia coli (ETEC) in vivo. This study provides a new alternative for producing the ETEC vaccine using the chloroplast expression system.

Data were analyzed using descriptive statistics and the obtained data were analyzed using SPSS-16 software.Results: The frequency of ectopic pregnancy in Hamadan province during 2000-2010 was averagely 2.6 per 1000 pregnancies. Tubal pregnancy with 95.2% is the most prevalent type of ectopic pregnancy most of which had occurred in the right tube (52.4%. Most ectopic pregnancies (52.2% were in the age group of 25-34.Conclusion: The prevalence of ectopic pregnancy in Hamadan province during the mentioned years has been 2.6 in 1000 pregnancies, which is lower compared to many existing data. However, the prevalence of ectopic pregnancy in this province has increased over time, so that it has become 3.3 times as much from 2000-2010.

    Ectopic eruption of a tooth within the dentate region of the jaws is often noticed in clinical practice and is well documented in the literature. But the ectopic eruption into the non dentate region is rare and scantly documented. The maxillary sinus is one such a non dentate region, apart from nasal septum, mandibular condyle, coronoid process and the palate, to accommodate such ectopic eruptions of teeth. Due to its rarity and lack of consensus over its management, the incidence deserves to be added to the literature and discussed. Early surgical intervention for removal of ectopic tooth along with enucleation of the associated cyst, if any, is the treatment of choice.

    Adenocarcinoma arising from jejunal ectopic pancreas is very rare. We report a case of a 69-year-old female with adenocarcinoma arising from jejunal ectopic pancreas after resection of advanced colon cancer. She underwent right hemicolectomy for advanced ascending colon cancer (ypT3N0M0, stage IIA) after chemotherapy. Two and half years after colectomy, her tumor markers were elevated, and computed tomography revealed a mass measuring 20 × 20 mm in the small intestine, having an abnormal uptake of (18)F-fluorodeoxyglucose on (18)F-fluorodeoxyglucose-positron emission tomography ((18)FDG-PET). Double-balloon enteroscopy revealed a submucosal tumor in the jejunum, and histopathology of biopsy specimens from that lesion showed ectopic pancreas without malignancy. Therefore, peritoneal metastasis from colon cancer concomitant with ectopic pancreas or adenocarcinoma arising from ectopic pancreas was considered as a differential diagnosis. She underwent laparoscopic jejunectomy. Pathological examination revealed a moderately differentiated adenocarcinoma arising from jejunal ectopic pancreas, not peritoneal metastasis from colon cancer. Even if histopathology of the biopsy specimen shows ectopic pancreas without malignancy, adenocarcinoma arising from ectopic pancreas should be considered when the tumor markers are elevated or the lesion has an abnormal uptake of (18)FDG.

    The management of ectopic pancreas is not well defined. This study aims to determine the prevalence of symptomatic ectopic pancreas and identify those who may benefit from treatment, with a particular focus on robotically assisted surgical management. Our institutional pathology database was queried to identify a cohort of ectopic pancreas specimens. Additional clinical data regarding clinical symptomatology, diagnostic studies, and treatment were obtained through chart review. Nineteen cases of ectopic pancreas were found incidentally during surgery for another condition or found incidentally in a pathologic specimen (65.5%). Eleven patients (37.9%) reported prior symptoms, notably abdominal pain and/or gastrointestinal bleeding. The most common locations for ectopic pancreas were the duodenum and small bowel (31% and 27.6%, respectively). Three out of 29 cases (10.3%) had no symptoms, but had evidence of preneoplastic changes on pathology, while one harbored pancreatic cancer. Over the years, treatment of ectopic pancreas has shifted from open to laparoscopic and more recently to robotic surgery. Our experience is in line with existing evidence supporting surgical treatment of symptomatic or complicated ectopic pancreas. In the current era, minimally invasive and robotic surgery can be used safely and successfully for treatment of ectopic pancreas.

    Full Text Available Bilateral ectopic pregnancy is a rare twin gestation with only a few cases reported in the literature. We report a 30 year old woman without any high risk factor for ectopic pregnancy, who had concurrent bilateral ectopic pregnancy. A 30 year old female presented to the Gynecology emergency department complaining of vaginal bleeding and abdominal pain. The presumptive diagnosis of ruptured left sided ectopic pregnancy was made on basis of clinical findings and ultrasound finings. An emergency laparotomy was done revealed a hemoperitoneum of 1.5 liters, a ruptured left tubal pregnancy with active bleeding and right tubal un-ruptured ectopic was found. A bilateral salpingectomy was performed. Histopathology confirmed presence of chorionic villi in both tubes. In theory, laparoscopic salpingostomy is the best surgical approach in bilateral tubal pregnancy. However, bilateral salpingectomy may be necessary when both tubes are extensively damaged or are actively bleeding. Successful pregnancies have been reported after conservative surgical treatment of bilateral ectopic, but the risk of recurrence is high. Our decision for an emergency laparotomy followed by bilateral salpingectomy was based on the fact that the patient presented with acute abdomen and was haemodynamically unstable and there was extensive bilateral tubal damage. As the incidence of ectopic pregnancies is increasing concurrently with the incidences of pelvic inflammatory disease and use of assisted fertility techniques; it may be that these and ldquo;rare ectopics and rdquo; will become less uncommon.

    Full Text Available Abstract Porcine pleuropneumonia caused by Actinobacillus pleuropneumoniae accounts for serious economic losses in the pig farming industry worldwide. We examined here the immunogenicity and protective efficacy of the recombinant type IV fimbrial subunit protein ApfA as a single antigen vaccine against pleuropneumonia, or as a component of a multi-antigen preparation comprising five other recombinant antigens derived from key virulence factors of A. pleuropneumoniae (ApxIA, ApxIIA, ApxIIIA, ApxIVA and TbpB. Immunization of pigs with recombinant ApfA alone induced high levels of specific serum antibodies and provided partial protection against challenge with the heterologous A. pleuropneumoniae serotype 9 strain. This protection was higher than that engendered by vaccination with rApxIVA or rTbpB alone and similar to that observed after immunization with the tri-antigen combination of rApxIA, rApxIIA and rApxIIIA. In addition, rApfA improved the vaccination potential of the penta-antigen mixture of rApxIA, rApxIIA, rApxIIIA, rApxIVA and rTbpB proteins, where the hexa-antigen vaccine containing rApfA conferred a high level of protection on pigs against the disease. Moreover, when rApfA was used for vaccination alone or in combination with other antigens, such immunization reduced the number of pigs colonized with the challenge strain. These results indicate that ApfA could be a valuable component of an efficient subunit vaccine for the prevention of porcine pleuropneumonia.

  1. Evolution of Salmonella enterica virulence via point mutations in the fimbrial adhesin.

    Directory of Open Access Journals (Sweden)

    Dagmara I Kisiela

    Full Text Available Whereas the majority of pathogenic Salmonella serovars are capable of infecting many different animal species, typically producing a self-limited gastroenteritis, serovars with narrow host-specificity exhibit increased virulence and their infections frequently result in fatal systemic diseases. In our study, a genetic and functional analysis of the mannose-specific type 1 fimbrial adhesin FimH from a variety of serovars of Salmonella enterica revealed that specific mutant variants of FimH are common in host-adapted (systemically invasive serovars. We have found that while the low-binding shear-dependent phenotype of the adhesin is preserved in broad host-range (usually systemically non-invasive Salmonella, the majority of host-adapted serovars express FimH variants with one of two alternative phenotypes: a significantly increased binding to mannose (as in S. Typhi, S. Paratyphi C, S. Dublin and some isolates of S. Choleraesuis, or complete loss of the mannose-binding activity (as in S. Paratyphi B, S. Choleraesuis and S. Gallinarum. The functional diversification of FimH in host-adapted Salmonella results from recently acquired structural mutations. Many of the mutations are of a convergent nature indicative of strong positive selection. The high-binding phenotype of FimH that leads to increased bacterial adhesiveness to and invasiveness of epithelial cells and macrophages usually precedes acquisition of the non-binding phenotype. Collectively these observations suggest that activation or inactivation of mannose-specific adhesive properties in different systemically invasive serovars of Salmonella reflects their dynamic trajectories of adaptation to a life style in specific hosts. In conclusion, our study demonstrates that point mutations are the target of positive selection and, in addition to horizontal gene transfer and genome degradation events, can contribute to the differential pathoadaptive evolution of Salmonella.

    FimH is an adhesive subunit of type 1 fimbriae expressed by different enterobacterial species. The enteric bacterium Klebsiella pneumoniae is an environmental organism that is also a frequent cause of sepsis, urinary tract infection (UTI), and liver abscess. Type 1 fimbriae have been shown to be critical for the ability of K. pneumoniae to cause UTI in a murine model. We show here that the K. pneumoniae fimH gene is found in 90% of strains from various environmental and clinical sources. The fimH alleles exhibit relatively low nucleotide and structural diversity but are prone to frequent horizontal-transfer events between different bacterial clones. Addition of the fimH locus to multiple-locus sequence typing significantly improved the resolution of the clonal structure of pathogenic strains, including the K1 encapsulated liver isolates. In addition, the K. pneumoniae FimH protein is targeted by adaptive point mutations, though not to the same extent as FimH from uropathogenic Escherichia coli or TonB from the same K. pneumoniae strains. Such adaptive mutations include a single amino acid deletion from the signal peptide that might affect the length of the fimbrial rod by affecting FimH translocation into the periplasm. Another FimH mutation (S62A) occurred in the course of endemic circulation of a nosocomial uropathogenic clone of K. pneumoniae. This mutation is identical to one found in a highly virulent uropathogenic strain of E. coli, suggesting that the FimH mutations are pathoadaptive in nature. Considering the abundance of type 1 fimbriae in Enterobacteriaceae, our present finding that fimH genes are subject to adaptive microevolution substantiates the importance of type 1 fimbria-mediated adhesion in K. pneumoniae.

    Full Text Available Ectopic pregnancies occur in approximately 1.4% of all pregnancies and account for 15% of pregnancy-related deaths. Considering the high degree of mortality, recognizing an ectopic pregnancy is important. Signs and symptoms of an ectopic pregnancy are nonspecific and include pain, vaginal bleeding, and an adnexal mass. Therefore, imaging can play a critical role in diagnosis. There are different types of ectopic pregnancies, which are tubal, cornual, cesarean scar, cervical, heterotopic, abdominal, and ovarian. Initial imaging evaluation of pregnant patients with pelvic symptoms is by ultrasonography, transabdominal, transvaginal or both. We review the sonographic appearance of different types of ectopic pregnancies that will aid in accurate and prompt diagnosis.

    This retrospective cohort study reviewed the diagnosis of all ectopic pregnancies within a district general hospital over a 5-year period after the establishment of a dedicated Early Pregnancy Assessment Unit (EPAU). Of 215 ectopic pregnancies identified, notes were available for 208 (97%). Two-hundred and two cases were determined to have been diagnosed and managed as ectopic pregnancies. Six cases were excluded as they were pregnancies of unknown location managed as such. Overall, 91% were diagnosed by ultrasound scan, 5% were diagnosed clinically and 3% were diagnosed on serial human chorionic gonadotrophin (hCG) levels. This study found that the introduction of a dedicated, multi-professional, EPAU with a stable workforce improved ultrasound visualisation of ectopic pregnancies at first ultrasound scan from 22% prior to its commencement, to 61% over this period. The improvement in positive scan diagnosis of ectopic pregnancy was associated with a reduction in negative laparoscopy rate from 13% to 6%.

    Full Text Available Purpose: Ectopic tooth within the tooth bearing region is often noticed in clinical practice but ectopic eruption in non-dentate regions like maxillary sinus is rare. Rarer is the presence of multiple ectopic teeth involving both the maxillary incisors and canine and has not been reported yet. Method: A seventeen year old male presented with a complaints of dull pain on the right side of the face for past two years. Water’s view X-ray of PNS revealed dense non-specific opacification of the right maxillary sinus. Result: Antrostomy through Caldwell–Luc approach revealed three ectopic teeth in the right maxillary sinus. Later the teeth were identified to be central incisor, lateral incisor and canine. Conclusion: Rare finding of ectopic incisors in the maxillary sinus is reported and the need for interdisciplinary approach to patients is stressed upon.

    Full Text Available Background and aim: Ovarian pregnancy is an uncommon form of ectopic pregnancy which usually diagnosed so late. The aim of this study is to report a case of ovarian ectopic pregnancy Case presentation: A 19 years old woman, with a history of polycystic ovary, first pregnancy, gestation age 9 weeks and 4 days, visited the doctor. She was complaining of severe abdomen pain and vaginal spotting and she was bedridden because of threatened miscarriage. She had discharged from hospital with progesterone suppository prescription. Requesting a transvaginal ultrasound and heterogeneous echogenic mass (size18×8/5 was shown near the left ovary. It was shown as ectopic pregnancy. The patient was hospitalized by ectopic pregnancy in ovary diagnosis and she was treated by methotrexate. Conclusion: In pregnant women that complain of bleeding and spotting in early pregnancy, in addition to threatened abortion, ectopic pregnancy should exist even in the absence of clinical symptoms, should be considered.

    2008-12-01

    Full Text Available Abstract Background Salmonella enterica is a facultative intracellular pathogen of worldwide importance. Over 2,500 serovars exist and infections in humans and animals may produce a spectrum of symptoms from enteritis to typhoid depending on serovar- and host-specific factors. S. Enteritidis is the most prevalent non-typhoidal serovar isolated from humans with acute diarrhoeal illness in many countries. Human infections are frequently associated with direct or indirect contact with contaminated poultry meat or eggs owing to the ability of the organism to persist in the avian intestinal and reproductive tract. The molecular mechanisms underlying colonisation of poultry by S. Enteritidis are ill-defined. Targeted and genome-wide mutagenesis of S. Typhimurium has revealed conserved and host-specific roles for selected fimbriae in intestinal colonisation of different hosts. Here we report the first systematic analysis of each chromosomally-encoded major fimbrial subunit of S. Enteritidis in intestinal colonisation of chickens. Results The repertoire, organisation and sequence of the fimbrial operons within members of S. enterica were compared. No single fimbrial locus could be correlated with the differential virulence and host range of serovars by comparison of available genome sequences. Fimbrial operons were highly conserved among serovars in respect of gene number, order and sequence, with the exception of safA. Thirteen predicted major fimbrial subunit genes were separately inactivated by lambda Red recombinase-mediated linear recombination followed by P22/int transduction. The magnitude and duration of intestinal colonisation by mutant and parent strains was measured after oral inoculation of out-bred chickens. Whilst the majority of S. Enteritidis major fimbrial subunit genes played no significant role in colonisation of the avian intestines, mutations affecting pegA in two different S. Enteritidis strains produced statistically significant

    During the last decades the incidence of ectopic pregnancy has been steadily rising. The chosen therapy has usually been unilateral salpingectomy. Recently, different conservative (tube-preserving) treatment-modalities have been introduced in clinical practice. We have tried conservative treatment by local injection of prostaglandin F2a (total dose 2-4 mg) directly into the tubal pregnancy and, if feasible, also into the corpus luteum graviditate. The treatment was successful in 13 out of 16 patients. In one patient laparotomia was performed because of pain, and revealed a haematoma in fossa Douglasi. Reinjection of prostaglandin was necessary in one patient because of rising HCG titres. One patient was hospitalized for four days because of nausea and pain. The treatment was otherwise successful. The method may be useful as a non-surgical alternative in haemodynamically stable patients without tubal rupture. Further studies are needed to evaluate the outcome in terms of future fertility.

    Approximately 2.1% to 8.6% of all pregnancies after IVF with embryo transfer have been reported to be ectopic. In this report, we present a case of presumed intestinal microperforation caused by an ectopic pregnancy following IVF. A 29-year-old woman presented with rectal bleeding. She had previously been treated for an ectopic pregnancy for which she had received two doses of methotrexate. Colonoscopy and abdominal CT angiography were performed and showed that the ectopic pregnancy was attached to the sigmoid colon. Surgery was performed to remove the ectopic pregnancy. Because intestinal microperforations were suspected, the patient received intravenous antibiotic therapy during her hospitalization. In cases of intestinal bleeding, clinicians should consider the possibility of intestinal involvement of an ectopic pregnancy, even if the response to treatment for the ectopic pregnancy has been appropriate.

    Ectopic parathyroid adenomas are considered the main cause of primary hyperparathyroidism. However, concurrent parathyroid and thymic pathologies are rarely diagnosed in the same patient. A 47-year-old man with history of diabetes mellitus, hypertension, and myasthenia gravis presented with persistent hypercalcemia. Laboratory investigations, computed tomography, and technetium-99 m sestamibi scintigraphy revealed ectopic parathyroid glands, a mediastinal mass, and an enlarged thymus. The patient underwent thymectomy and mass excision via a median sternotomy. Histopathology was consistent with ectopic parathyroid adenoma and thymolipoma. The serum calcium and parathormone concentrations normalized within 48 hours after surgery. © The Author(s) 2016.

    Full Text Available The objective of the study was to Safe Medical management of ectopic pregnancy in those where surgical management was indicated. Patients with one or more criteria not suitable for medical treatment but refusing surgical management were included. Exclusion criteria were those who were not haemodynamically stable. They were managed with close monitoring as inpatient to assess resolution of ectopic with Methotrexate. All five cases have been managed successfully by medical method. There is a possible role for medical management in patients who might not satisfy the criteria fully, however further research is needed. Ectopic pregnancy is life threatening disorder. With advances in diagnostic approaches such as ultrasound coupled with hormone markers diagnosis of ectopic has become easier in cases having first trimester bleeding per vaginum. Ectopic can be managed expectantly, medically and surgically. Medical management includes Inj. Methotrexate (MTX. In this case series we have studied five cases which are managed successfully with hundred percent successful results by medical management despite not satisfying criteria. It is a retrospective study. So from this study we can conclude that we can manage ectopic pregnancies medically based upon clinical judgment.

In the era of artificial reproductive techniques and liberated life style, ectopic pregnancy is not rare. However, ovarian pregnancy is an uncommonly encountered variety of ectopic pregnancy, and a definitive preoperative diagnosis is very challenging. Intraoperative findings and histopathology usually provide the final diagnosis. High serum beta human chorionic gonadotrophin levels, lack of an intrauterine gestational sac, tubo ovarian mass on ultrasonography (USG, patient’s risk factors, in addition to the Spiegelberg’s criteria gives a high probability of ovarian pregnancy. Management with surgical approach is required in all cases. We have made an attempt to present a case of ovarian pregnancy, consistent with Spiegelberg’s criteria.

    Embryo in uterine implantation is a complex and multifactor-related process and is a downstream and ideal point for woman fertility control.Understanding the cellular and molecular mechanism of implantation is a prerequisite for development of anti-implantation contraceptives.In spite of considerable accumulation of information from the laboratory animals that has been achieved,it is difficult to generate such information in human due to ethical restriction and experimental limitation,and the present knowledge for understanding the definitive mechanisms which control these events remains elusive.Embryo implantation can also occur outside uterus.Some women with abdominal pregnancies could successfully complete the processes of gestation and bear normal babies,implying that implantation itself may be not an endometrium-specific process.Reproductive biologists should cooperate with gynecologists to further comparatively study the molecular and cellular mechanisms of implantation normally occurring in endometrium and abnormally appearing outside uterine cavity.Such collaborative studies may generate new important information for developing anti-implantation contraceptive and for techniques of accurate diagnosis of ectopic pregnancy.A specially designed GnRH-2 analog and a combination use of Iow dose RU486 and gossypol as anti-implantation contraceptives have been suggested.

    Ectopic pregnancy (EP), in which a fertilized ovum implants outside the uterine cavity, is the leading cause of pregnancy-related death in the first trimester. EP is usually suspected by a positive pregnancy test and an empty uterus on transvaginal sonography (TVS). Although TVS is the initial modality of choice, it may occasionally fail to demonstrate the implantation site. When TVS findings are indeterminate, magnetic resonance imaging (MRI) may provide better delineation of the focus of EP owing to its excellent tissue contrast. The key MRI features of EP include gestational sac (GS)-like structures that typically appear as a cystic sac-like structure, frequently associated with surrounding acute hematoma of distinct low intensity on T2-weighted images. In tubal pregnancy, an enhanced tubal wall on postcontrast images may be another diagnostic finding. Ruptured EP is inevitably associated with acute hematoma outside these structures. In intrauterine EP, recognition of the relationship between GS-like structure and the myometrium can aid in differentiating from normal pregnancy. Diagnostic pitfalls include heterotopic pregnancy, decidual changes in endometrial cyst and theca lutein cysts mimicking GS-like structures. Knowledge of a spectrum of clinical and MRI features of EP is essential for establishing an accurate diagnosis and determining appropriate management. (orig.)

    Ectopic liver tissue can develop at various sites near the liver. Ectopic hepatocellular carcinomas (HCCs) arising from ectopic liver tissue have a rare clinical incidence. A very rare case has been observed to have metastasis after operation. We report an extremely rare case with multiple masses which were identified in the head and body of the pancreas. Ectopic hepatocellular carcinomas. The masses were removed by surgical resection. Histopathological analysis showed that both masses were ectopic HCC. The patient was still alive and did not have metastasis and relapse. The literature review for this rare case is also presented to highlight the risk of ectopic HCC and good prognosis of operation for ectopic HCC.

    Ectopic pregnancies are a serious gynaecological emergency that can be fatal. As such, prompt diagnosis and safe timely treatment is essential. Here, we review the literature on the development of molecularly targeted diagnostics and therapeutics for ectopic pregnancy. A blood-based biomarker that accurately identifies an ectopic pregnancy could be used to offer early diagnostic certainty in cases where ultrasound cannot determine the location of the embryo ('a pregnancy of unknown location'). Molecules examined so far can be broadly grouped into biological themes of relevance to reproduction: (i) Fallopian tube (dys)function, (ii) embryo/trophoblast growth, (iii) corpus luteum function, (iv) inflammation, (v) uterine function and (vi) angiogenesis. While a sensitive and specific biomarker for ectopic pregnancy has yet to be identified, it is possible that improvements in platform technologies or a multi-modal biomarker approach may yield an accurate diagnostic biomarker test. Furthermore, with the advent of better imaging technology, the need for a blood-based biomarker test may be superseded by improvements in ultrasound or magnetic resonance imaging technology. There have been some recent preclinical studies describing molecularly targeted therapeutic approaches for ectopic pregnancy. Notably, bench-to-bedside studies have examined the use of combination gefitinib (orally available epidermal growth factor receptor inhibitor) and methotrexate. Preclinical studies suggest that combination gefitinib and methotrexate is highly effective in inducing placental cell death, and is significantly more effective than methotrexate alone. In early human trials, encouraging preliminary efficacy data have shown that combination gefitinib and methotrexate can rapidly resolve tubal ectopic pregnancies, and large extra-tubal ectopic pregnancies. If a large clinical randomized controlled trial confirms these findings, combination gefitinib and methotrexate could become a new

    Ectopic eruption of teeth into a region other than the oral cavity is rare although there have been reports of teeth in the nasal septum, mandibular condyle, coronoid process, palate, chin and maxillary sinus. Occasionally, a tooth may erupt in the maxillary sinus and present with local sinonasal symptoms attributed to chronic sinusitis. We present a case of an ectopic maxillary third molar tooth that caused chronic purulent sinusitis in relation to the right maxillary sinus.

    Arrhythmia is a condition in which an additional ectopic pacemaker is present in the tissue of the heart. Localization of ectopic foci is essential for successful radio-frequency ablation, an important surgical way of treating arrhythmia. In one of the possible mechanisms, arrhythmia induced by an ectopic foci located in one of the main blood vessels leading out or onto the heart. The therapeutic procedure in this case is usually ablation of the whole junction of the blood vessel with heart wall. In this way, whatever excitation occurs inside the vessel, it cannot penetrate the ventricles perturbing their contraction cycle. Such an ablation procedure is long and burdened with the risk of the perforation. A more safe method would involve the localization of the source of the excitation (i.e. the ectopic foci) and its ablation. The methods used in cardiology at present involve complicated localization systems and are time-consuming with the patient spending a long time on the operating table. Recently, Hall and Glass have developed numerical methods which allow to quickly to model the localization of the ectopic foci in a flat, square sample of an inhomogeneous medium. Here, we demonstrate an extension of this model for the case of a cylinder containing an ectopic foci, that can be a model of a blood vessel with the source of the ectopic beat inside it. Three methods of localization are implemented. Standard electrodes containing several active tips are used to stimulate the medium locally and locate the foci judging from the reaction of the system. The first one uses electrode activation times to compute the location of the ectopic site. The second one localizes it by measuring the resetting response of the foci, and the third one, uses wavefront curvature. Specifically for the cylindrical geometry of the blood vessel, we developed a localization procedure that allows to quickly localize the pacemaker.

    Conclusions: The early diagnosis of an ectopic pregnancy is one of the greatest challenges for a physician. It requires a high index of suspicion to diagnose an ectopic pregnancy. The importance of an early diagnosis lies in the fact that the lady can be offered a conservative line of management which can definitely have a beneficial effect on her reproductive career.

    Ectopic pregnancy affects 1% to 2% of all pregnancies and is responsible for 9% of pregnancy-related deaths in the United States. When a pregnant patient presents with first-trimester bleeding or abdominal pain, physicians should consider ectopic pregnancy as a possible cause. The patient history, physical examination, and imaging with transvaginal ultrasonography can usually confirm the diagnosis. When ultrasonography does not clearly identify the pregnancy location, the physician must determine whether the pregnancy is intrauterine (either viable or failing) or ectopic. Use of the beta subunit of human chorionic gonadotropin (ß-hCG) discriminatory level, the ß-hCG value above which an intrauterine pregnancy should be visualized by transvaginal ultrasonography, may be helpful. Failure to visualize an intrauterine pregnancy when ß-hCG is above the discriminatory level suggests ectopic pregnancy. In addition to single measurements of ß-hCG levels, serial levels can be monitored to detect changes. ß-hCG values in approximately 99% of viable intrauterine pregnancies increase by about 50% in 48 hours. The remaining 1% of patients have a slower rate of increase; these patients may have pregnancies that are misdiagnosed as nonviable intrauterine or ectopic. After an ectopic pregnancy has been confirmed, treatment options include medical, surgical, or expectant management. For patients who are medically unstable or experiencing life-threatening hemorrhage, a surgical approach is indicated. For others, management should be based on patient preference after discussion of the risks, benefits, and monitoring requirements of all approaches.

    Ectopic pregnancy is common among young women. Treatment can consist of either surgery with salpingectomy or salpingostomy or medical management with methotrexate. In addition to acute complications, treatment of ectopic pregnancy can result in long-term sequelae that include decreased fertility. Little is known about the patterns of care and predictors of treatment in women with ectopic pregnancy. Similarly, data on outcomes for various treatments are limited. We examined the patterns of care and outcomes for women with ectopic pregnancy. Specifically, we examined predictors of medical (vs surgical) management of ectopic pregnancy and tubal conservation (salpingostomy vs salpingectomy) among women who underwent surgery. The Perspective database was used to identify women with a diagnosis of tubal ectopic pregnancy treated from 2006-2015. Perspective is an all-payer database that collects data on patients at hospitals from throughout the United States. Women were classified as having undergone medical treatment, if they received methotrexate, and surgical treatment, if treatment consisted of salpingostomy or salpingectomy. Multivariable models were developed to examine predictors of medical treatment and of tubal conserving salpingostomy among women who were treated surgically. Among the 62,588 women, 49,090 women (78.4%) were treated surgically, and 13,498 women (21.6%) received methotrexate. Use of methotrexate increased from 14.5% in 2006 to 27.3% by 2015 (Pectopic pregnancy. There are significant race- and insurance-related disparities associated with treatment.

    The advent of interventional radiology enabled remarkable advances in diagnosis and treatment of several situations in obstetrics and gynecology. In the field of obstetrics, these advances include temporary occlusion of the iliac arteries to the management of placenta accreta and/or prior, arteriovenous fistulas after embolization of uterine curettage and management of ectopic uterine and extra-uterine pregnancies. The non-tubal ectopic pregnancy, either cervical, abdominal, ovarian or in a cesarean scar, often represents major therapeutic challenge, especially when exists a desire to maintain fertility. Despite the systemic methotrexate therapy and surgical resection of the ectopic gestational sac be the most used therapeutic options, the interventionist approach of non-tubal ectopic pregnancies, direct injection of methotrexate in the gestational sac and intra-arterial chemoembolization of uterine arteries constitute in the currently literature viable, safe, effective modalities with low morbidity, shorter hospital stay, and rapid clinical recovery. Because of little variety of materials used, and the increase in training of specialists in the area, the radiological intervention as a treatment option in ectopic pregnancies is financially viable and present considerable accessibility in the world and at most of Brazilian medical centers.

    Full Text Available Introduction: Ectopic pregnancy is a pregnancy with extrauterine implantation. This situation is gynecologic emergency that contributes to maternal mortality. Therefore, early recognition, based on identification of the causes of ectopic pregnancy risk factors, is needed. Methods: The design descriptive observational. The samples were pregnant women who had ectopic pregnancy at Maternity Room, Emergency Unit, Dr. Soetomo Hospital, Surabaya, from 1 July 2008 to 1 July 2010. Sampling technique was total sampling using medical records. Result: Patients with ectopic pregnancy were 99 individuals out of 2090 pregnant women who searched for treatment in Dr. Soetomo Hospital. However, only 29 patients were accompanied with traceable risk factors. Discussion:. Most ectopic pregnancies were in the age group of 26-30 years, comprising 32 patients (32.32%, then in age groups of 31–35 years as many as 25 patients (25.25%, 18 patients in age group 21–25 years (18.18%, 17 patients in age group 36–40 years (17.17%, 4 patients in age group 41 years and more (4.04%, and the least was in age group of 16–20 years with 3 patients (3.03%. A total of 12 patients with ectopic pregnancy (41.38% had experience of abortion and 6 patients (20.69% each in groups of patients with ectopic pregnancy who used family planning, in those who used family planning as well as ectopic pregnancy patients with history of surgery. There were 2 patients (6.90% of the group of patients ectopic pregnancy who had history of surgery and history of abortion. The incidence rate of ectopic pregnancy was 4.73%, mostly in the second gravidity (34.34%, whereas the nulliparous have the highest prevalence of 39.39%. Acquired risk factors, i.e. history of operations was 10.34%, patients with family planning 20.69%, patients with history of abortion 41.38%, patients with history of abortion and operation 6.90% patients with family and history of abortion was 20.69%.

    Ectopic pregnancy is an important cause of maternal morbidity and mortality. Women who experience fragmented care may undergo unnecessary delays to diagnosis and treatment. Based on ectopic pregnancy cases observed in clinical practice that raised our concern about fragmentation of care, we designed an exploratory study to describe the number, characteristics, and outcomes of fragmented care among patients with ectopic pregnancy at one urban academic hospital. Chart review with descriptive statistics. Fragmented care was defined as a patient being evaluated at an outside facility for possible ectopic pregnancy and transferred, referred, or discharged before receiving care at the study institution. Of 191 women seen for possible or definite ectopic pregnancy during the study period, 42 (22 %) met the study definition of fragmented care. The study was under-powered to observe statistically significant differences across groups, but we found concerning, non-significant trends: patients with fragmented care were more likely to be Medicaid recipients (65.9 vs. 58.8 %) and to experience a complication (23.8 vs. 18.1 %) compared to those with non-fragmented care. Most patients (n = 37) received no identifiable treatment prior to transfer and arrived to the study hospital with no communication to the receiving hospital from the outside provider (n = 34). Nine patients (21 %) presented with ruptured ectopic pregnancies. The fragmentation we observed in our study may contribute to previously identified socio-economic disparities in ectopic pregnancy outcomes. If future research confirms these findings, health information exchanges and regional coordination of care may be important strategies for reducing maternal mortality.

    To investigation the diagnosis and treatment of ectopic adrenocorticotrophic hormone (ACTH) syndrome. The clinical characters of 57 cases of ecotopic ACTH syndrome from Jan. 1996 to Dec. 2016 were collected and analyzed. The 57 cases included 32 males and 25 females. The age ranged from 11 to 68 years (average 32 years). ACTH levels significantly increased from 16.5 to 365.6 pmol/L, with average 77.6 pmol/L (normal range ectopic ACTH syndrome cases (44%) were group A, without identified source of ectopic hormone, were treated with bilateral or unilateral adrenalectomy due to the severity of the disease and difficulty of operation. Group B was composed of 16 cases (28%) diagnosed as ectopic ACTH syndrome by finding ectopic ACTH tumors and surgical resection. Group C included 16 cases (28%) with nonsurgical therapy. Different treatment results and prognosis were analyzed. In the study, 40 cases of the 57 had been followed up for 6 months to 10 years. In group A, of the 25 cases with bilateral or unilateral adrenalectomy, 4 died of diabetes and severe pulmonary infection, 18 survived, and 3 were lost to the follow-up, and the survival rate was 81% (18/22). In group B, of the 16 cases with radical tumor resection, 5 died of tumor recurrence 0.5-6.0 years after operation, 3 survived, and 8 were lost to the follow-up, and the survival rate was 37.5% (3/8). In group C, of the 16 non-operation patients, 4 with radiotherapy and chemotherapy died of metastases, diabetes or pulmonary infection, 6 with chemotherapy died of pulmonary infection within 1 year and the others were lost to the follow-up, and the survival rate was 0. Ectopic ACTH syndrome is difficult to treat. Adrenalectomy is effective for the management of ectopic ACTH syndrome, especially for those patients with severe Cushing's syndrome, but the primary tumor can not be located.

    In order to evaluate the clinical and sonographic findings in 60 patients with ectopic pregnancy confirmed at laparotomy, we carried out a prospective study at the Hospital de Gineco-Obstetricia del Centro Médico León, Instituto Mexicano del Seguro Social. The patients were 28.17 years old, average. The ectopic pregnancy was more common in multiparous women (80%) than in nuliparous ones. The obstetric risk factors more frequent were abortion (26.6%) and use of intrauterine device (23.3%). The clinical sign reported most common was pelvic pain, referred in 48 patients (80%). Hemodynamic changes were detected in 21.6% of the cases. The ultrasound findings were seen in most of the patients and heterogeneous adnexal mass was observed in 91.6% of them, moreover intraperitoneal fluid was reported in 61.6% of the patients with ectopic pregnancy. The heterogeneous adnexal mass had a direct relationship with the diagnosis of ectopic pregnancy and had a correlation coefficient value R = 0.99 (P < 0.01). The ultrasonographic findings seen with transvaginal technique were similar than those obtained through transabdominal procedure. We conclude that ultrasonography has a definite role in improving the diagnosis of ectopic pregnancy.

    Macroscopic ectopic or heterotopic ganglionic tissue within the cauda equina is a very rare pathological finding and is usually associated with spinal dysraphism. However, it may mimic genuine neoplasms of the cauda equina. The authors describe a 29-year-old woman with a history of back pain, right leg pain, and urinary incontinence in whom imaging demonstrated an enhancing mass located in the cauda equina at the L1-2 interspace. The patient subsequently underwent biopsy and was found to have a focus of ectopic ganglionic tissue that was 1.3 cm in greatest dimension. To the authors' knowledge, ectopic or heterotopic ganglionic tissue within the cauda equina in a patient without evidence of spinal dysraphism has never been reported. This patient presented with imaging and clinical findings suggestive of a neoplasm, and an open biopsy proved the lesion to be ectopic ganglionic tissue. The authors suggest that ectopic ganglionic tissue be added to the list of differential diagnoses of a space-occupying lesion arising from the cauda equina.

    Kidney in ectopic position is dysplasic, and associated to other malformations. The advent of a lithiasis in these conditions rises questions about therapeutic options. We report on five observations of pelvic ectopic kidney with urinary lithiasis. Patients were aged from 16 to 42 years. Kidney was non functional in two cases, or with normal appearance sized 10 to 12 cm. We performed total nephrectomy in two cases, pyelolithotomy in the other cases. Surgical approach was subperitoneal via iliac route. A dismembered pyeloplasty was associated in one case. All patients did well. Radiologic control at 6 and 12 months showed no recurrence in a well functioning kidney. Surgical lithotomy is advocated as a treatment in urinary lithiasis affecting ectopic kidney. It is an easy procedure which permits correction of other associated malformations.

    Full Text Available Maxillary canine impactation is often encountered in orthodontic clinical practice and the aetiology is associated to genetic factors as well as local space factors. If preventive treatment is not started in ectopic maxillary canines, some possible consequences may occur, such as resorption of the roots of the neighboring permanent teeth, cysts, ankylosis and expensive surgical and orthodontic treatment. The aim of this review was to preset several early treatment modalities for ectopic maxillary canines based on recent scientific evidence. Four are the most important: Only extractions intervention, extraction of deciduous canines with cervical pull headgear, active intervention in late mixed dentition and active intervention in early mixed dentition. These different modalities showed a greater increasing the rate of normal eruption of ectopic canines ( 80-97%. The extraction of primary canine alone is still an effective method to prevent canine impactation, whose success rate would be increased if some other method interceptive is added.

    Primary intraorbital ectopic meningiomas are rare and their existence remains controversial. We present a 30-year-old female with painless, non-axial proptosis and a palpable superomedial mass. The MRI demonstrated that the mass had no optic nerve sheath or sphenoid wing involvement and was initially reported to have no intracranial extension. The patient was initially thought to have an ectopic orbital meningioma. Subsequent multidisciplinary team (MDT) consultation and further specialist review of the MRI revealed a subtle dural tail connecting to an enhancing mass in the olfactory groove. Biopsy revealed a WHO Grade 1 transitional meningioma with an infiltrative pattern. We argue that some previously reported cases of ectopic meningioma may lack the requisite imaging to discover the primary disease. Our report highlights the importance of MRI in this group of patients and the role of a skull-base MDT with specialist neuroradiology input to determine the true origin and extent of these extradural orbital meningiomas.

    To describe extreme hyperprolactinemia originating from a pituitary adenoma in the wall of an ovarian dermoid. This is a description of an unusual case and a review of ectopic prolactin production. Ectopic production of prolactin is a rare condition that has been reported in isolated organ system pathology including ovaries. An ovarian dermoid is a benign neoplasm that has the potential for active unregulated endocrine function. Hyperprolactinemia can result from functioning lactotrophs found in ovarian dermoids and can lead to clinical sequelae. Definitive treatment of the condition requires surgical removal of the functioning endocrine tissue. Extreme hyperprolactinemia caused by a pituitary tumor located within a dermoid has not been reported before. We present a case of profound hyperprolactinemia originating from a pituitary adenoma found in the wall of an ovarian dermoid and give a broad overview of the condition and literature. Ectopic prolactin production should always be considered in symptomatic patients found to have elevated serum levels and no findings on brain imaging.

    Full Text Available Levonorgestrel Emergency Contraception (LNG-EC is the safest and the most commonly used oral regimen that can be used after an unprotected intercourse. Although it is highly effective, failures can occur especially if it is used in the peri /or postovulatory period. It can not inhibit ovulation if used in these periods and the altered tubal motility together with the ciliary dysfunction can prevent the transfer of the fertilized ovum from the fallopian tube to the endometrial cavity, causing an ectopic pregnancy, which is one of the important concerns after failed LNG-EC. This risk was reported not to be higher than the risk of ectopic pregnancy observed in the general population, but the users of this medication should still warned about this risk. Here we report a case of ectopic pregnancy from Turkey after midcyclic use and failure of LNG-EC. [Int J Reprod Contracept Obstet Gynecol 2013; 2(4.000: 749-750

    2013-03-15

    A major roadblock in the biomedical treatment of human sensory disorders, including blindness, has been an incomplete understanding of the nervous system and its ability to adapt to changes in sensory modality. Likewise, fundamental insight into the evolvability of complex functional anatomies requires understanding brain plasticity and the interaction between the nervous system and body architecture. While advances have been made in the generation of artificial and biological replacement components, the brain's ability to interpret sensory information arising from ectopic locations is not well understood. We report the use of eye primordia grafts to create ectopic eyes along the body axis of Xenopus tadpoles. These eyes are morphologically identical to native eyes and can be induced at caudal locations. Cell labeling studies reveal that eyes created in the tail send projections to the stomach and trunk. To assess function we performed light-mediated learning assays using an automated machine vision and environmental control system. The results demonstrate that ectopic eyes in the tail of Xenopus tadpoles could confer vision to the host. Thus ectopic visual organs were functional even when present at posterior locations. These data and protocols demonstrate the ability of vertebrate brains to interpret sensory input from ectopic structures and incorporate them into adaptive behavioral programs. This tractable new model for understanding the robust plasticity of the central nervous system has significant implications for regenerative medicine and sensory augmentation technology.

    Ectopic eruption of the first permanent molar is a relatively common occurence in the developing dentition. A range of treatment options are available to the clinician provided that diagnosis is made early. Non-treatment can result in premature exfoliation of the second primary molar, space loss and impaction of the second premolar. This paper will describe the management of ectopic first permanent molars, using clinical examples to illustrate the available treatment options. CLINICAL RELEVANCE: This paper is relevant to every general dental practitioner who treats patients in mixed dentition.

    Full Text Available Hydatidiform moles are abnormal gestations characterized by the presence of hydropic changesaffecting some or all of the placental villi. Hydatidiform moles arise as a result of the fertilizationof an abnormal ovum. In this report, the patient was a 29 year old Asian woman who had inductionof ovulation with letrozol. Since the majority of molar gestations arise within the uterine cavitythus the occurrence of a hydatidiform mole within ectopic gestational tissue is rare. It is importantto differentiate a hydatidiform mole from a conventional ectopic pregnancy, particularly in infertilewomen who have a history of ovulation induction.

    The development of intranasal ectopic teeth is rare. Although they are more commonly seen in the palate and maxillary sinus, they can also be found in the mandibular condyle, coronoid process, and nasal cavity. A 30-year-old male patient presented with a complaint of headache. Computed tomography of the paranasal sinuses showed a bony mass in the right maxillary sinus wall, 1 cm in size. He did not have any history of maxillofacial trauma or operation. The mass was removed via a Caldwell-Luc procedure. It looked like a tooth. Histopathologic diagnosis was made as ectopic molar tooth. The patient was asymptomatic two weeks after the operation.

    Proteus mirabilis strains were isolated from dogs with urinary tract infection (UTI) and fimbriae were prepared from two strains. The N-terminal amino acid sequences of the major fimbrial subunits were determined and both sequences appeared identical to the N-terminal amino acid sequence of a urinary cell adhesin (UCA) (Wray, S. K., Hull, S. I., Cook, R. G., Barrish, J. & Hull, R. A., 1986, Infect Immun 54, 43-49). The genes of two different major fimbrial subunits were cloned using oligonucleotide probes that were designed on the basis of the N-terminal UCA sequence. Nucleotide sequencing revealed the complete ucaA gene of 540 bp (from strain IVB247) encoding a polypeptide of 180 amino acids, including a 22 amino acid signal sequence peptide, and the pmpA (P. mirabilis P-like pili) gene of 549 bp (from strain IVB219) encoding a polypeptide of 183 amino acids, including a 23 amino acid signal sequence. Hybridization experiments gave clear indications of the presence of both kinds of fimbriae in many UTI-related canine P. mirabilis isolates. However, the presence of these fimbriae could not be demonstrated in P. vulgaris or other Proteus-related species. Database analysis of amino acid sequences of major subunit proteins revealed that the UcaA protein shares about 56% amino acid identity with the F17A and F111A major fimbrial subunits from bovine enterotoxigenic Escherichia coli. In turn, the PmpA protein more closely resembled the pyelonephritis-associated pili (Pap)-like major subunit protein from UTI-related E. coli. The evolutionary relationship of UcaA, PmpA and various other fimbrial subunit proteins is presented in a phylogenetic tree.

    The presence of S and F1C/S-related fimbrial determinants was determined in 462 E. coli strains obtained from different extraintestinal infections and in 162 control isolates of E. coli by using two different DNA probes: an oligonucleotide probe consisting of three oligonucleotides that bind specifically to the S adhesin gene and a polynucleotide probe which is not able to distinguish between S, F1C, and S-related sequences. The expression of S and F1C phenotypes was tested by dot enzyme immunoassay with the corresponding monoclonal antibodies. S fimbriae genotypes were observed more frequently in septic (25%) and urinary (12%) isolates of E. coli than in faecal and water isolates (1%) and often occurred together with O2, O6, O18 and O83 antigens. F1C/S-related fimbrial DNA was detected with a higher frequency in UTI isolates (26%) than in septic (16%) and faecal (10%) isolates and was most frequently associated with O4, O6, and O75 serotypes. Since the production of S and F1C fimbriae was comparatively rare in all clinical and control isolates of E. coli, DNA hybridization assays which allow the sensitive and specific detection of fimbrial determinants even in the absence of their expression are preferable to phenotypic assays.

    To demonstrate a technique for the laparoscopic surgical management of cesarean section scar ectopic pregnancy. Step-by-step presentation of the procedure using video (Canadian Task Force classification III). Cesarean section scar ectopic pregnancy is a rare form of ectopic pregnancy with an incidence ranging from 1:1800 to 1:2216. Over the last decade, the incidence seems to be on the rise with increasing rates of cesarean deliveries and early use of Doppler ultrasound. These pregnancies can lead to life-threatening hemorrhage, uterine rupture, and hysterectomy if not managed promptly. Local or systemic methotrexate therapy has been used successfully but can result in prolonged hospitalization, requires long-term follow-up, and in some cases treatment can fail. In the hands of a trained operator, laparoscopic resection can be performed to manage this type of pregnancy. Consent was obtained from the patient, and exemption was granted from the local Internal Review Board (The Womens' Hospital, Parkville). In this video we describe our technique for laparoscopic management of a cesarean scar ectopic pregnancy. We present the case of a 34-year-old G4P2T1 with the finding of a live 8-week pregnancy embedded in the cesarean section scar. The patient had undergone 2 previous uncomplicated cesarean sections at term. On presentation her β-human chorionic gonadotropin (β-hCG) level was 52 405 IU/L. She was initially managed with an intragestational sac injection of potassium chloride and methotrexate, followed by 4 doses of intramuscular methotrexate. Despite these conservative measures, the level of β-hCG did not adequately fall and an ultrasound showed a persistent 4-cm mass. A decision was made to proceed with surgical treatment in the form of a laparoscopic resection of the ectopic pregnancy. The surgery was uneventful, and the patient was discharged home within 24 hours of her procedure. Her serial β-hCG levels were followed until complete resolution

    Ectopic pregnancy is associated with maternal morbidity and mortality during early pregnancy. Ectopic pregnancy occurs in approximately 2% of all pregnancies, and the risk of ectopic pregnancy is increased by eight-fold in women with a history of eopic pregnancy. However, recurrent ectopic pregnancy after ipsilateral partial salpingectomy is quite rare. The authors experienced a case of recurrent ectopic pregnancy in the distal remnant after right partial salpingectomy. In this case report, they discuss this unusual case and provide a brief review of the literature.

    To describe the radiological findings associated with ectopic ureterocele and ectopic ureter in pediatric patients. To assess the role of ultrasound (US), serial micturating cystourethrography (SM-CU) and intravenous urography (IVU) in the diagnosis of these two entities. The authors performed a retrospective study of 132 patients, 73 with ectopic ureterocele and 59 with ectopic ureter. The imaging studies used were US, SMCU, IVU and methods to determine renal function (diuretic renography and renal scintigraphy). The findings were confirmed during surgery in every case. The most common radiological findings in ectopic ureterocele were renal duplication (86,3%). vesicoureteral reflux (VUR) to the lower half of the kidney (46.6%), dilatation of the lower pole of the kidney (38.4%) and contralateral duplication (30.1%). In boys, the ectopic ureter entered via bladder neck and posterior urethra (73.7%) or into seminal vesicles (15.8%); in girls, it went to vagina (32.5%), bladder neck (30%) or urethra (22.5%). Renal duplication was associated in 64.4%, with VUR to the ectopic ureter in 21% while there was a single renal system in 35.6%, with VUR to the ectopic ureter in 57.1% and contralateral renal agenesis in 19%. Eighteen patients (13.6%) presented a single, dy plastic, nonfunctioning renal system (6 cases of ureterocele and 12 of ectopic ureter). Knowledge of the embryological development of ureteral duplication is essential for the understanding of these two entities and helps to differentiate between them, thus facilitating a sometimes complicated diagnosis. Ectopic ureters and ureteroceles accompanied by a single, dysplastic renal system are associated with a greater incidence of congenital anomalies and a higher rate of complications than the duplicate systems. A prenatal US examination enables early diagnosis. The anatomical information provided by US is, on occasion, more valuable than that resulting from IVU or SMCU, However, IVU is indispensable in girls

    The impact of an ectopic pregnancy in the next generation is unknown. Our aim was to compare reproductive outcomes in daughters of women with and without ectopic pregnancy. Designed as a historical prospective controlled cohort study with data collected in four Danish registries from 1977-2009, women with ectopic pregnancy during 1977-1982 were age-matched to women without ectopic pregnancy. Daughters of these two cohorts were followed until 2009. We compared 5126 daughters of women with ectopic pregnancy with 19 928 daughters of women without ectopic pregnancy. The daughters of women with ectopic pregnancy had a 1.5-fold (95% confidence interval 1.2-1.9) increased risk of ectopic pregnancy, while for deliveries this was 1.0 (1.0-1.1), for miscarriages 1.1 (1.0-1.2), and for induced abortions 1.3 (1.2-1.4). Daughters of mothers with ectopic pregnancy have a 50% higher risk of ectopic pregnancy than daughters of women without an ectopic pregnancy, but a normal delivery rate.

    Ectopic parathyroid adenomas can occur in numerous anatomic locations. While ectopic parathyroid adenomas can rarely occur in the pharyngeal region, this has not previously been described in the soft palate. We report the first case of ectopic parathyroid adenoma within the soft palate. A 59 year old woman presented with hyperparathyroidism. She remained persistently hyperparathyroid after initial parathyroidectomy. Repeat exploration for a lesion suspicious on PET-CT for an ectopic parathyroid adenoma in the parapharyngeal region was unsuccessful in treating the hyperparathyroidism. An ectopic adenoma in the soft palate was eventually discovered. Removal through a transoral approach was successful in treating the hyperparathyroidism. Ectopic parathyroid adenomas can occur in various anatomical locations that may be missed even with the use of the various imaging modalities. The soft palate should be added to the list of possible ectopic locations high in the neck.

  13. Structures of C-mannosylated anti-adhesives bound to the type 1 fimbrial FimH adhesin

    Directory of Open Access Journals (Sweden)

    Jerome de Ruyck

    2016-05-01

    Full Text Available Selective inhibitors of the type 1 fimbrial adhesin FimH are recognized as attractive alternatives for antibiotic therapies and prophylaxes against Escherichia coli infections such as urinary-tract infections. To construct these inhibitors, the α-d-mannopyranoside of high-mannose N-glycans, recognized with exclusive specificity on glycoprotein receptors by FimH, forms the basal structure. A hydrophobic aglycon is then linked to the mannose by the O1 oxygen inherently present in the α-anomeric configuration. Substitution of this O atom by a carbon introduces a C-glycosidic bond, which may enhance the therapeutic potential of such compounds owing to the inability of enzymes to degrade C-glycosidic bonds. Here, the first crystal structures of the E. coli FimH adhesin in complex with C-glycosidically linked mannopyranosides are presented. These findings explain the role of the spacer in positioning biphenyl ligands for interactions by means of aromatic stacking in the tyrosine gate of FimH and how the normally hydrated C-glycosidic link is tolerated. As these new compounds can bind FimH, it can be assumed that they have the potential to serve as potent new antagonists of FimH, paving the way for the design of a new family of anti-adhesive compounds against urinary-tract infections.

    The objective of this research was to determine whether variation in the presence of fimbrial protein SefD would impact efficacy of bacterins as measured by recovery of Salmonella enterica serovar Enteritidis (Salmonella Enteritidis) from the spleens of hens. Two bacterins were prepared that varied in SefD content. Also, two adjuvants were tested, namely, water-in-oil and aluminum hydroxide gel (alum). Control groups for both adjuvant preparations included infected nonvaccinated hens and uninfected nonvaccinated hens. At 21 days postinfection, Salmonella Enteritidis was recovered from 69.7%, 53.1%, and 86.0% from the spleens of all hens vaccinated with bacterins lacking SefD, bacterins that included SefD, and infected nonvaccinated control hens, respectively. No Salmonella was recovered from uninfected nonvaccinates. Results from individual trials showed that both bacterins reduced positive spleens, but that the one with SefD was more efficacious. Alum adjuvant had fewer side effects on hens and egg production as compared to water-in-oil. However, adjuvant did not change the relative recovery of Salmonella Enteritidis from spleens. These results suggest that SefD is a promising target antigen for improving the efficacy of immunotherapy in hens, and is intended to reduce Salmonella Enteritidis in the food supply.

  15. Role of P-fimbrial-mediated adherence in pyelonephritis and persistence of uropathogenic Escherichia coli (UPEC) in the mammalian kidney.

    Science.gov (United States)

    Lane, M C; Mobley, H L T

    2007-07-01

    P fimbria, a mannose-resistant adhesin of uropathogenic Escherichia coli (UPEC), has been shown to be associated with acute pyelonephritis. The pap gene cluster encodes the proteins required for P-fimbrial biogenesis, including papG, which encodes the tip adhesin. The three most studied PapG molecular variants, which are shown to bind distinct isoreceptors, are PapGI, -II, and -III. PapGII preferentially binds globoside, or GbO4, a glycolipid isoreceptor of the human kidney. Studies using different animal models of ascending urinary tract infection (UTI) have demonstrated a variable role for P fimbriae, and specifically PapGII-mediated adherence, in renal colonization. The disparities in the results obtained from those studies are likely to be attributed to the differences in animal models and UPEC strains utilized. One explanation that is discussed in detail is the contribution of multiple fimbriae of UPEC that potentially mediate adherence to the mammalian kidney. Overall, P fimbriae appear to play some role in mediating adherence to uroepithelial cells in vivo and establishing an inflammatory response during renal colonization, thus contributing to kidney damage during acute pyelonephritis. To verify that P fimbriae contribute to the pathogenesis of UPEC during ascending UTI (and in particular acute pyelonephritis), future studies should be conducted to satisfy fully all three tenets of the molecular Koch's postulates, including complementation of a mutated allele.

  16. Strong inhibition of fimbrial 3 subunit gene transcription by a novel downstream repressive element in Bordetella pertussis.

    The Bvg-regulated promoters for the fimbrial subunit genes fim2 and fim3 of Bordetella pertussis behave differently from each other both in vivo and in vitro. In vivo Pfim2 is significantly stronger than Pfim3 , even though predictions based on the DNA sequences of BvgA-binding motifs and core promoter elements would indicate the opposite. In vitro Pfim3 demonstrated robust BvgA∼P-dependent transcriptional activation, while none was seen with Pfim2 . This apparent contradiction was investigated further. By swapping sequence elements we created a number of hybrid promoters and assayed their strength in vivo. We found that, while Pfim3 promoter elements upstream of the +1 transcriptional start site do indeed direct Bvg-activated transcription more efficiently than those of Pfim2 , the overall promoter strength of Pfim3  in vivo is reduced due to sequences downstream of +1 that inhibit transcription more than 250-fold. This element, the DRE (downstream repressive element), was mapped to the 15 bp immediately downstream of the Pfim3 +1. Placing the DRE in different promoter contexts indicated that its activity was not specific to fim promoters, or even to Bvg-regulated promoters. However it does appear to be specific to Bordetella species in that it did not function in Escherichia coli.

    We describe the 2D reformatted and 3D volume rendered images by MDCT in a patient with an episode of acute bleeding from the colonic stoma. This case indicates that the 2D reformatted and 3D volume rendered images are useful to detect this rare complication of portal hypertension, and they help to tailor adequate treatment for the patients with bleeding from stomal varices. Ectopic varices are an uncommon cause of gastrointestinal hemorrhage, but they account for up to 5% of all variceal bleedings (1). Bleeding from stomal varices has been reported in up to 20% of the patients suffering with chronic liver failure with permanent stoma (2). However, the diagnosis of stomal varices is difficult because bleeding from stoma may also be associated with lower gastrointestinal bleeding. To the best of our knowledge, the 2D reformatted and 3D volume rendered images by MDCT for visualization of ectopic stomal varices have not been previously reported in the medical literature.

    Full Text Available Duodenal lipomas are relatively uncommon and are rarely responsible for clinical symptoms. Occasionally, searching for aetiology of gastrointestinal bleeding leads to the final diagnosis of duodenal lipomas. Here, we present the case of a 68-year-old woman who suffered with repeated melena and weight loss. Endoscopy, abdominal computed tomography (CT and histopathological outcomes are described in this case of duodenal lipoma with ectopic duodenal glands.

    Perforation of jejunal diverticulum is a rare complication. Here, we report a case of jejunal diverticulum penetration with surrounding ectopic pancreas. An 83-year-old female patient was admitted to our department with acute onset of severe abdominal pain lasting for half a day. Abdominal computed tomography showed outpouching of the small intestine that contained air/fluid, with multiple surrounding air bubbles in the mesentery of the small intestine. She was diagnosed with penetration of the small intestine, and an emergency laparotomy was indicated. The penetrated jejunal diverticulum was identified ~20-cm distal to the ligament of Treitz. Partial resection of the jejunum was performed, and her postoperative course was uneventful. The pathological findings confirmed diverticulum penetration into the mesentery and severe inflammation at the site, with surrounding ectopic pancreas. Furthermore, the pancreatic ducts were opened through the penetrated diverticulum. This rare case shows that the ectopic pancreas might have caused penetration of jejunal diverticulum owing to the pancreatic duct opening through the diverticulum.

    2017-04-01

    Helicobacter pylori infection can cause peptic ulceration and is associated with gastric adenocarcinoma. This study aimed to construct and characterize a non-virulent Vibrio cholerae O1 strain, which grows more rapidly than H. pylori, as vector for H. pylori antigens for possible use as a vaccine strain against H. pylori. This was done by recombinant expression of the H. pylori adhesion antigen HpaA alone or, as a proof of principle, together with different colonization factor (CF) antigens of enterotoxigenic Escherichia coli (ETEC) which may enhance immune responses against HpaA. A recombinant V. cholerae strain co-expressing HpaA and a fimbrial CF antigens CFA/I or CS5, but not the non-fimbrial CF protein CS6, was shown to express larger amounts of HpaA on the surface when compared with the same V. cholerae strain expressing HpaA alone. Mutations in the CFA/I operon showed that the chaperon, possibly together with the usher, was involved in enhancing the surface expression of HpaA. Oral immunization of mice with formaldehyde-inactivated recombinant V. cholerae expressing HpaA alone or together with CFA/I induced significantly higher serum antibody responses against HpaA than mice similarly immunized with inactivated HpaA-expressing H. pylori bacteria. Our results demonstrate that a non-virulent V. cholerae strain can be engineered to allow strong surface expression of HpaA, and that the expression can be further increased by co-expressing it with ETEC fimbrial antigens. Such recombinant V. cholerae strains expressing HpaA, and possibly also other H. pylori antigens, may have the potential as oral inactivated vaccine candidates against H. pylori.

    Ectopic ureters are often very difficult to diagnose with conventional diagnostic modalities (physical examination, ultrasound, intravenous urography, cystography, urethro-cystoscopy, isotop examinations) in children. The authors report their experience with a relatively new method, the magnetic resonance urography (MRU) diagnosing ectopic ureters in childhood. MRU was used in 7 girls to detect an ectopic ureter in the last 3 years. On the basis of typical clinical signs, an ectopic ureter was suspected in all patients, but it could not be demonstrated by conventional diagnostic methods. Thus, MRU was done to confirm the suspected diagnosis. In all of the 7 patients, the examinations demonstrated ectopic ureters with the intraoperative findings further confirming the pre-operative diagnosis. In 2 patients, the intraoperative findings of the upper urinary tract anomalies were slightly different from the MRU report. The MRU is a reliable diagnostic method to diagnose ectopic ureters which are not easily detectable with conventional diagnostic modalities.

    Abdominal ectopic pregnancy is an extremely rare entity, which represents 1% of all ectopic pregnancies and is associated with high maternal and fetal morbidity and mortality. The maternal mortality risk of an abdominal ectopic pregnancy is seven to eight times greater than the risk of a tubal ectopic pregnancy and is 90 times greater than the risk of intrauterine pregnancy. This is a disease of difficult diagnosis that often takes place late. We report the case of a patient with an abdominal ectopic pregnancy, which was diagnosed by abdominal ultrasound in the second trimester; the patient was suc- cessfully treated with exploratory laparotomy with complete removal of the fetus and placenta. We provide a review of the literature on the risk factors for abdominal ectopic pregnancy, diagnostic tests and therapeutic options.

    2011-01-01

    Full Text Available Bleeding from ectopic varices, which is rare in patients with portal hypertension, is generally massive and life-threatening. Forty-three patients were hospitalized in our ward for gastrointestinal bleeding from ectopic varices. The frequency of ectopic varices was 43/1218 (3.5% among portal hypertensive patients in our ward. The locations of the ectopic varices were rectal in thirty-two, duodenal in three, intestinal in two, vesical in three, stomal in one, and colonic in two patients. Endoscopic or interventional radiologic treatment was performed successfully for ectopic varices. Hemorrhage from ectopic varices should be kept in mind in patients with portal hypertension presenting with lower gastrointestinal bleeding.

    2011-06-01

    Full Text Available The ectopic thyroid gland is a rare entity which is mostly found along the line of descent of"nthe thyroid gland. Most of the patients present with midline swelling and usually seek medical"nattention. Dual ectopic thyroid gland is even rarer. The clinical examination and different imaging"nmodalities establish its diagnosis. Radionuclide studies are highly sensitive and specific in"ndemonstrating the functional tissues in patients with ectopic thyroid, thereby guiding further"nmanagement. The authors reported a case of ectopic thyroid gland in a girl with midline neck"nswelling initially, subsequently lost to follow-up. She again presented with enlarged swelling after"na period of three years with dual ectopic thyroid in the neck region on thyroid scan. Thyroid"nscintigraphy demonstrated that progression in the size of ectopic glands was due to neglect in"ntreatment.

    A DNA fragment encoding the cholera toxin A2 subunit (CTA2) linked to the enterotoxigenic Escherichia coli (ETEC) colony forming fimbrial antigen CFA/I was inserted into a plant expression vector containing the cholera toxin B subunit (CTB) fused to the rotavirus enterotoxin 22 amino acid epitope NSP422. Anti-CFA/I antibodies recognized a single band of approximately 72-kDa in transformed potato tuber tissue consistent with CFA/I-CTA2 and CTB-NSP4 fusion protein assembly into a cholera holotoxin-like structure. Enzyme-linked immunosorbent assay (GM1 ELISA) indicated that the CFA/I-CTA2 fusion protein bound specific GM1 ganglioside membrane receptors and made up approximately 0.002% of the total soluble tuber protein. Oral immunization of BALB/c mice with transformed tuber tissues generated anti-CFA/I serum and intestinal IgG and IgA secretory antibodies. Attachment of ETEC H10407 to enterocyte-like Caco-2 human colon carcinoma cells incubated with antiserum from immunized mice was reduced by 15% in comparison with Caco-2 cells incubated with serum from unimmunized mice. Immunogold staining of bacterial preparations revealed deposition of gold particles on E. coli H10407 fimbria incubated with immune serum but not on fimbria treated with sera from unimmunized mice demonstrating the specificity of antibodies in the immune serum for binding to CFA/I protein containing fimbria. The protection against toxic E. coli binding to Caco-2 cells generated by antisera from mice immunized with plant-synthesized CFA/I antigen demonstrates the feasibility of plant-based multi-component vaccine protection against enterotoxigenic E. coli, rotavirus and cholera, three enteric diseases that together exert the highest levels of child morbidity and mortality in economically emerging countries.

  7. Crosstalk between virulence loci: regulation of Salmonella enterica pathogenicity island 1 (SPI-1) by products of the std fimbrial operon.

    Science.gov (United States)

    López-Garrido, Javier; Casadesús, Josep

    2012-01-01

    Invasion of intestinal epithelial cells is a critical step in Salmonella infection and requires the expression of genes located in Salmonella pathogenicity island 1 (SPI-1). A key factor for SPI-1 expression is DNA adenine (Dam) methylation, which activates synthesis of the SPI-1 transcriptional activator HilD. Dam-dependent regulation of hilD is postranscriptional (and therefore indirect), indicating the involvement of unknown cell functions under Dam methylation control. A genetic screen has identified the std fimbrial operon as the missing link between Dam methylation and SPI-1. We show that all genes in the std operon are part of a single transcriptional unit, and describe three previously uncharacterized ORFs (renamed stdD, stdE, and stdF). We present evidence that two such loci (stdE and stdF) are involved in Dam-dependent control of Salmonella SPI-1: in a Dam(-) background, deletion of stdE or stdF suppresses SPI-1 repression; in a Dam(+) background, constitutive expression of StdE and/or StdF represses SPI-1. Repression of SPI-1 by products of std operon explains the invasion defect of Salmonella Dam(-) mutants, which constitutively express the std operon. Dam-dependent repression of std in the ileum may be required to permit invasion, as indicated by two observations: constitutive expression of StdE and StdF reduces invasion of epithelial cells in vitro (1,000 fold) and attenuates Salmonella virulence in the mouse model (>60 fold). In turn, crosstalk between std and SPI-1 may play a role in intestinal infections by preventing expression of SPI-1 in the caecum, an intestinal compartment in which the std operon is known to be expressed.

    A sensitive and specific detection method was developed for Xanthomonas hyacinthi; this method was based on amplification of a subsequence of the type IV fimbrial-subunit gene fimA from strain S148. The fimA gene was amplified by PCR with degenerate DNA primers designed by using the N-terminal and C-terminal amino acid sequences of trypsin fragments of FimA. The nucleotide sequence of fimA was determined and compared with the nucleotide sequences coding for the fimbrial subunits in other type IV fimbria-producing bacteria, such as Xanthomonas campestris pv. vesicatoria, Neisseria gonorrhoeae, and Moraxella bovis. In a PCR internal primers JAAN and JARA, designed by using the nucleotide sequences of the variable central and C-terminal region of fimA, amplified a 226-bp DNA fragment in all X. hyacinthi isolates. This PCR was shown to be pathovar specific, as assessed by testing 71 Xanthomonas pathovars and bacterial isolates belonging to other genera, such as Erwinia and Pseudomonas. Southern hybridization experiments performed with the labelled 226-bp DNA amplicon as a probe suggested that there is only one structural type IV fimbrial-gene cluster in X. hyacinthi. Only two Xanthomonas translucens pathovars cross-reacted weakly in PCR. Primers amplifying a subsequence of the fimA gene of X. campestris pv. vesicatoria (T. Ojanen-Reuhs, N. Kalkkinen, B. Westerlund-Wikström, J. van Doorn, K. Haahtela, E.-L. Nurmiaho-Lassila, K. Wengelink, U. Bonas, and T. K. Korhonen, J. Bacteriol. 179: 1280-1290, 1997) were shown to be pathovar specific, indicating that the fimbrial-subunit sequences are more generally applicable in xanthomonads for detection purposes. Under laboratory conditions, approximately 1,000 CFU of X. hyacinthi per ml could be detected. In inoculated leaves of hyacinths the threshold was 5,000 CFU/ml. The results indicated that infected hyacinths with early symptoms could be successfully screened for X. hyacinthi with PCR.

    We present 9 cases of ectopic parathyroid lesions in which histological diagnosis is confirmed. We analyze the findings of imaging modalities including {sup 99m}Tc-MIBI scintigraphy, Tl-Tc subtraction imaging, ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI), and we assess the usefulness of those imagings in determination of the location of the ectopic parathyroid lesion. MIBI scintigraphy was thought to be most useful for detection of the ectopic parathyroid lesion. (author)

    Ectopic molar pregnancy is a rare occurrence and consequently not often considered as a diagnostic possibility. We report two cases of molar hydatidiform tubal pregnancy. Diagnosis of ectopic pregnancy was confirmed on clinical biological and sonographic investigations. Diagnosis of molar pregnancy was done on histopathology. The clinical course was favorable for both patients. Although rare, molar changes can occur at any site of an ectopic pregnancy. Clinical diagnosis of a molar pregnancy is difficult but histopathology is the gold standard for diagnosis.

    Full Text Available Abstract Background Olfactory receptors (ORs are the largest gene family in the human genome. Although they are expected to be expressed specifically in olfactory tissues, some ectopic expression has been reported, with special emphasis on sperm and testis. The present study systematically explores the expression patterns of OR genes in a large number of tissues and assesses the potential functional implication of such ectopic expression. Results We analyzed the expression of hundreds of human and mouse OR transcripts, via EST and microarray data, in several dozens of human and mouse tissues. Different tissues had specific, relatively small OR gene subsets which had particularly high expression levels. In testis, average expression was not particularly high, and very few highly expressed genes were found, none corresponding to ORs previously implicated in sperm chemotaxis. Higher expression levels were more common for genes with a non-OR genomic neighbor. Importantly, no correlation in expression levels was detected for human-mouse orthologous pairs. Also, no significant difference in expression levels was seen between intact and pseudogenized ORs, except for the pseudogenes of subfamily 7E which has undergone a human-specific expansion. Conclusion The OR superfamily as a whole, show widespread, locus-dependent and heterogeneous expression, in agreement with a neutral or near neutral evolutionary model for transcription control. These results cannot reject the possibility that small OR subsets might play functional roles in different tissues, however considerable care should be exerted when offering a functional interpretation for ectopic OR expression based only on transcription information.

    Ectopic pregnancy is commonly seen as a differential diagnosis of first-trimester vaginal bleeding. Often the diagnosis is made based on a combination of exam findings, transvaginal ultrasound, and a positive pregnancy test. Our case describes a patient with a history of ectopic pregnancy treated with methotrexate and serial human chorionic gonadotropin measurements that were decreasing appropriately. At the time of evaluation, her urine pregnancy test was negative; however, she was confirmed to have a ruptured tubal ectopic pregnancy. This case highlights the variable presentation of ectopic pregnancies and the importance of combining exam findings with ultrasound and laboratory results.

    Ectopic thyroid is a rare developmental anomaly with lingual thyroid accounting for majority of the cases. The presence of ectopic thyroid tissue lateral to the midline is very rare, and very few cases located in the submandibular region have been reported. The simultaneous finding of submandibular ectopic thyroid tissue and a functional orthotopic thyroid gland is even rarer. In the differential diagnosis of an ectopic submandibular thyroid, it is fundamental to exclude a metastasis from well-differentiated thyroid cancer, even when primary thyroid carcinoma is not demonstrable.

    Full Text Available Dentigerous cysts are the most common type of developmental odontogenic cysts arising from the crowns of impacted, embedded, or unerupted teeth. They constitute about 20% of all epithelium-lined cysts of the jaws. The teeth involved most often are mandibular third molar and maxillary canines. About 70% of dentigerous cysts occur in the mandible and 30% in the maxilla. Dentigerous cysts associated with ectopic teeth within the maxillary sinus are fairly rare, and only 20 cases had been reported in Medline since 1980. In the present paper, we report an additional case of dentigerous cysts associated with ectopic third molar in the right maxillary sinus. Also, pathogenesis of ectopic tooth, role of advanced imaging, differential diagnosis, and management are discussed.

    The presence of simultaneous two ectopic foci of thyroid tissue (dual ectopic thyroid) is rare, and few cases have been reported in the literature. The ectopic thyroid tissue is an extremely uncommon embryological aberration due to the alterations occurring during the embryological development with incomplete migration of thyroid precursors. Commonly ectopic thyroid tissue is a midline structures, but the lateral location is possible but very rare. Ectopic thyroid is common in women and can vary in size from a microscopic focus to a few centimeters. The normal process of migration of the thyroid can be interrupted at various levels determining a lingual ectopy, a sublingual ectopic, prelaryngeal ectopy, or mediastinic ectopy. Intrathoracic and subdiaphragmatic organs are other sites where the ectopic thyroid tissue may be present. In most of the cases, ectopic tissue is a lingual thyroid and this condition can be totally asymptomatic, discovered incidentally, or occurs with symptoms such as dysphonia, dysphagia, dyspnea, and hemoptysis. Sublingual or suprahyoid ectopia is rare and even rarer are the cases of two foci of ectopic thyroid tissue simultaneously present. On imaging, the ectopic tissue shows the same characteristics of orthotopic thyroid tissue and similarly can undergo goiterous and cancerous transformation. We report a case of incidental dual ectopic thyroid in lingual and suprahyoid level in a 72-year-old female patient, asymptomatic and with normal thyroid function, who underwent computed tomography (CT) angiography before vascular surgery for the treatment of carotid stenosis. The presence of a lingual thyroid can lead to a difficult and dangerous intubation, with possible fatal consequences. For this reason, the discovery of these abnormalities has totally changed the patient management who has been subjected to endovascular treatment, instead to the classical surgery.

    Ectopic preganacies are unsuccessful pregnancies that result from implantation of fertilized ovum occurring in an aberrant area. Aside from an emergency case, the early diagnosis of ectopic pregnancy is very difficult particularly in a case with insidious onset and mild clinical manifestations. Early diagnosis not only reduces the danger, but also simplifies the management of ectopic pregnancy. Ultrasonography has been an indispensable diagnostic tool in Obstetrics and Gynecology. In the authors' experience, clinical suspected ectopic pregnancy was one of the common indications for performing ultrasonography. Since Kobayashi at al. reported the appearances of ectopic pregnancy utilizing bistable B-scan ultrasonography, the ultrasonic findings of ectopic pregnancy have been reported by many authors. But, its accuracy and reliability in the diagnosis of ectopic pregnancy are still open to controversy. The authors studied 65 cases of clinically suspected ectopic pregnancy with Picker 80 L gray scale ultrasonography from Aug. 1982 to June. 1983. There were 29 confirmed cases, of which 15 were proved to have ectopic pregnancy and 14 were proved to have diseases other than ectopic pregnancy by surgical and histopathological study or by laparoscopy and follow up study. 29 confirmed cases were reviewed. The results were as follows: 1. Among 15 ectopic pregnancies, there were 12 ampullary pregnancies, 2 isthmic pregnancies and 1 interstitial pregnancy. Among 14 cases of no ectopic pregnancy, there were 5 intrauterine pregnancies, 3 myoma uteri, 2 P.I.D., and 1 case of dermoid cyst, cystic teratoma, H-mole and tubal hematoma due to previous tuball ligation, respectively. 2. The age distribution of ectopic pregnancy was from 22 to 41 years. The common clinical manifestations of ectopic pregnancy were lower abdominal pain (73.3%), vaginal spotting or bleeding (73.3%) and amenorrhea (66.7%). 3. Positive result of urine immunologic pregnancy test was 28.6% in ectopic

    Full Text Available Background & Objectives: Ectopic pregnancy is one of the common medical emergencies encountered in the clinical practice. Confirmation of diagnosis is usually done by urine pregnancy test and transabdominal sonography. Thus, the present study is carried out to determine the role of transabdominal ultrasonography in the diagnosis of ectopic pregnancy by comparing the ultrasonography findings with that of operative and histopathology and to evaluate clinical profile of the women with confirmed ectopic pregnancy. Materials & Methods: Transabdominal ultrasound record of patients referred for first trimester ultrasound, from January 2008 to December 2015, at radiology department of Kist medial college teaching hospital were reviewed to identify patients with ectopic pregnancy. Among these patients those who underwent surgery and histopathology confirmed ectopic pregnancies were identified and their medical records were retrieved. Ultrasound and clinical profile were recorded and statistically analyzed. Results: There were 19 patients with ultrasound diagnosis of ectopic pregnancy among 1480 first trimester ultrasound record. Among these patients, ectopic pregnancy was confirmed on 18 patients. Ultrasound diagnosis included adnexal mass with pelvic fluid in 15 (83.3% patients and pelvic fluid without adnexal mass in 4 (16.7% patients. The study result revealed that sensitivity of transabdominal ultrasonography was 100% and specificity was 99.9%. Positive predictive value and negative predictive value of transabdominal ultrasonography was 94% and 100%.Conclusion: The transabdominal ultrasound accurately diagnose ruptured ectopic pregnancy.JCMS Nepal. 2016;12(1:1-4.

    Full Text Available Ectopic adrenocorticotropic hormone (ACTH syndrome is caused most frequently by a bronchial carcinoid tumor or by small cell lung cancer. Medullary thyroid carcinoma (MTC is a rare etiology of ectopic ACTH syndrome. We describe a case of Cushing syndrome due to ectopic ACTH production from MTC in a 48-year-old male. He was diagnosed with MTC 14 years ago and underwent total thyroidectomy, cervical lymph node dissection and a series of metastasectomies. MTC was confirmed by the pathological examination of the thyroid and metastatic mediastinal lymph node tissues. Two years after his last surgery, he developed Cushingoid features, such as moon face and central obesity, accompanied by uncontrolled hypertension and new-onset diabetes. The laboratory results were compatible with ectopic ACTH syndrome. A bilateral adrenalectomy improved the clinical and laboratory findings that were associated with Cushing syndrome. This is the first confirmed case of ectopic ACTH syndrome caused by MTC in Korea.

    The incidence of ectopic pregnancy is approximately 2% of all pregnancies, and it remains the leading cause of death in early pregnancy. Over 95% of ectopic pregnancies are tubal pregnancies, and the remainders are nontubal pregnancies. The highest risk factor for ectopic pregnancy is a previous tubal pregnancy followed by previous tubal surgery, tubal sterilization, tubal pathology, and current intrauterine device use. The apparent increase in the incidence of nontubal ectopic pregnancy including heterotopic pregnancy may be attributed to the increasing number of pregnancies because of in vitro fertilization treatment. In most cases, an ectopic pregnancy can be treated medically with a single dose of methotrexate. Surgical treatment is still needed in women who are hemodynamically unstable and in those who do not fulfill the criteria for methotrexate treatment. Usually surgical treatment can be performed by laparoscopy and in some cases by hysteroscopy. Laparotomy is rarely needed even in women with intraperitoneal bleeding.

    Full Text Available Ovarian ectopic pregnancy (OEP is one of the rarest forms of nontubal ectopic pregnancies. Less than 1% of ectopic pregnancies are primary OEP. Exact etio-pathogenesis and predisposing factors for OEP are not yet well understood. Review of literature suggests its possible association with conditions like tubal sterilization, intrauterine contraceptive device (IUCD, IVF-ET in patients with bilateral salpingectomy etc. Clinical and radiological presentation often mimics like tubal ectopic pregnancy, making preoperative diagnosis difficult for clinicians. Thus, correct diagnosis can be made only intraoperatively using Speigelberg's criteria followed by histopathological confirmation. Treatment includes wedge resection of affected ovarian tissue or salpingo-oophorectomy in selected cases. We present a case series of primary ruptured ovarian ectopic pregnancy with no identifiable risk factors with inconclusive radiological diagnosis.

    Tumors originating from ectopic adrenal tissue are relatively rare. In this article, we describe a case with Cushing's syndrome caused by an ectopic adrenal adenoma. A 38 year-old male patient presenting with cushingoid appearance for 2 years was diagnosed to have ACTH-independent Cushing's syndrome based on endocrinological evaluation. Mutiple radiological examinations detected bilateral adrenal atrophy. When the images were investigated in a more expanded scope, a 3.0×3.5×5.3 cm mass was detected in the anterior of left renal hilum and left renal vein. The mass was successfully resected with intraoperative endoscopy and pathological evaluation revealed an ectopic adrenal tumor. It is suggested that when the endocrinlogically confirmed adrenal neoplasm could not be well and definitely localized, the possibility of ectopic adrenal should be presumed and further radiography examinations should extend to the field where ectopic adrenal usually presents.

    Full Text Available Lingual thyroid gland is a rare clinical entity. The presence of an ectopic thyroid gland located at the base of the tongue may be presented with symptoms like dysphagia, dysphonia, and upper airway obstruction. We are introducing a case of an 8-year-old girl who had lingual thyroid that presented dysphagia and foreign body sensation in the throat. The diagnostic was reached with clinical examination, thyroid scintigraphy with Tc99m and ultrasound. A laryngoscopy was performed which confirmed a spherical mass at base of tongue. Investigation should include thyroid function tests. In this case we observed subclinical hypothyroidism. There are different types of surgical approaches for the treatment of this condition; however, the treatment with Levothyroxine Sodium allowed the stabilization of TSH levels and clinical improvement of symptoms in a follow-up of 2 years.

The presence of an ectopic thyroid gland located at the base of the tongue may be presented with symptoms like dysphagia, dysphonia, and upper airway obstruction. We are introducing a case of an 8-year-old girl who had lingual thyroid that presented dysphagia and foreign body sensation in the throat. The diagnostic was reached with clinical examination, thyroid scintigraphy with Tc(99m) and ultrasound. A laryngoscopy was performed which confirmed a spherical mass at base of tongue. Investigation should include thyroid function tests. In this case we observed subclinical hypothyroidism. There are different types of surgical approaches for the treatment of this condition; however, the treatment with Levothyroxine Sodium allowed the stabilization of TSH levels and clinical improvement of symptoms in a follow-up of 2 years.

    Full Text Available A 36-year-old woman with 3 prior C-sections is diagnosed with a caesarean scar ectopic pregnancy. Despite receiving intramuscular and transvaginal methotrexate injection 2 months before presentation, the beta human chorionic gonadotropin was recorded to be 73 mIU/mL at the time of encounter. The patient complained of vaginal bleeding with a significant drop in hematocrit from 40% to 33%. Transvaginal ultrasound confirmed retroplacental hemorrhage and because of the patient's desire to retain fertility, interventional radiology was consulted to perform an uterine artery embolization. The uterine artery embolization was successful in achieving hemostasis and resulted in a decrease of betaHCG to 46 on postprocedure day 1 to <1 mIU/mL by postoperative week 3.

    Full Text Available Primary ovarian pregnancy is one of the rarest varieties of ectopic pregnancies. Patients frequently present with abdominal pain and menstrual irregularities. Intrauterine devices have evolved as probable risk factors. Preoperative diagnosis is challenging but transvaginal sonography has often been helpful. A diagnostic delay may lead to rupture, secondary implantation or operative difficulties. Therefore, awareness of this rare condition is important in reducing the associated risks. Here, we report two cases of primary ovarian pregnancies presenting with acute abdominal pain. Transabdominal ultrasonography failed to hint at ovarian pregnancy in one, while transvaginal sonography aided in the correct diagnosis of the other. Both cases were confirmed by histopathological examinations and were successfully managed by surgery.

    Full Text Available This work analyzes the data of cont emporary scientific literature regarding the ectopic mineralization in the prostate gland, its pathogenetic features are considered. The scientific literature of recent decades gives grounds to assert that the processes of concrement formation in the prostate gland are influenced by many factors, pathological mineralization can be realized by different mechanisms. They include chronic inflammation, stagnation fract ions in gland, reflux of urine from the urethra at intravesicle obstruction, malformation of prostate and seminal vesicles, specific inflammation, polymorphism of gene protein inhibitors of calcification. These mechanisms are interconnected, each of them may participate in the overall development of concrement fo rmation in the prostate. In recent years, due to improved instrumental diagnosis we observe a significant increase of the number of patients, who were found with pathogenic prostate gland biol iths, which requires more detailed and in-depth study of the mechanisms of mineral formation in the prostate.

    Full Text Available Ectopic breast is a congenital anomaly of the breast which can have varied presentations because of its different sites and pathologies arising from it. Lesions of ectopic breast tissue (EBT are commonly seen due to persistence of embryonic remnants along the milk line. They have also been reported from other sites like face, vulva, and perineum. They are prone to the same physiological and pathological alterations seen in the normal breast. Only 0.3% of breast carcinomas arise in the ectopic breast, whereas only a few cases of fibroadenoma have been reported at this site. We present a case of polymastia in a 21-year-old female in the inframammary region. We report two cases of fibroadenoma and carcinoma arising from EBT in the axilla of a 26 and 45-year females. Fibroadenoma was treated by simple excision while for carcinoma modified radical mastectomy was done followed by radiation and chemotherapy. Patient developed metastasis in the sternum. Carcinoma arising from EBT has a poorer prognosis and needs early diagnosis and treatment.

    To evaluate the ultrasound findings of ectopic pregnancy in the group of women examined in our department transvaginal ultrasound. Analysis of ectopic pregnancy cases covers the period from 1. 8. 2012. to 31. 9. 2015. We introduced several case studies. Retrospective analysis. Department of Gynecology and Obstetrics, Hospital Jindrichuv Hradec. The methodology is based on a retrospective evaluation of the history, laboratory and ultrasound findings in a group of 30 patients with ectopic pregnancy. At the first visit were diagnosed by transvaginal ultrasound 82% ectopic pregnancy. A patological adnexal mass was visualised in 84% cases. A negative ultrasound finding was observed in 16% cases. The results of our group of patients are more or less comparable with other studies. We recorded the same risk factors for ectopic pregnancy. Most ectopic pregnancies can be diagnosed at the first examination before starting treatment and treated at an early stage. Transvaginal ultrasound is the "gold standard" diagnostic tool of choice in the diagnosis of ectopic pregnancy in combination with the dynamics of serum levels β-hCG..

    Temporary ectopic implantation has been performed in clinical practice to salvage devascularized amputated tissues for delayed replantation purpose. In this study, we established a series of segmental forelimb ectopic implantation models in rats, including forelimb, forearm, forepaw, digit, and double forelimbs, to mimic the clinical context. Time of amputated limbs harvesting in donors and ectopic implantation process in recipients were recorded. Survival time and mortalities of recipients were also recorded. Sixty days after ectopic implantation, a full-field laser perfusion imager (FLPI) was used to detect the blood flow of amputated limbs and micro-CT imaging was used to examine bone morphological changes. Histological sections of amputated limbs were stained with hematoxylin and eosin to evaluate pathological changes. Implanted amputated limbs in all models achieved long term survival and there were no obvious morphological and histological changes were found according to results of micro-CT and histology study. Thus, a series of rat segmental forelimb temporary ectopic implantation models have been well established. To our knowledge, this is the first rodent animal model related to forelimb temporary ectopic implantation. These models might facilitate further research related to salvage, reconstruction and better aesthetic and functional outcome of upper extremity/digit in temporary ectopic implantation scenario.

    2006-09-01

    To evaluate the clinical features, aetiologic factors, challenging properties (such as radio opacity in Water's view in a patient with no sinusitis), signs and symptoms of the ectopic teeth in the maxillary sinus. Clinical symptoms and radiographic findings of 14 patients with ectopic teeth in the maxillary sinus were evaluated. Computed tomography (CT) and conventional radiographic images of maxillary sinus and clinical findings were compared with each other with regard to the final diagnosis. Water's view is inadequate to diagnose ectopic tooth in the maxillary sinus in some cases. Panoramic radiographs may be preferred before CT to evaluate the ectopic tooth in the maxillary sinus as structure of a tooth can be clearly detected on panoramic radiographs. Crowding was the most common aetiologic factor among the 14 cases. The patients with ectopic tooth in the maxillary sinus should be evaluated thoroughly by complete otorhinolaryngologic, intraoral examinations and proper diagnostic imaging procedures in order to avoid misdiagnosis of maxillary sinusitis. As the opacity of the maxillary sinus in Water's view due to ectopic tooth can be misinterpreted as maxillary sinusitis, patients who have sinusitis-like complaints and opacity of maxillary sinus in Water's view who are resistant to medical treatment should be evaluated with respect to the presence of ectopic tooth.

    Ectopic teeth erupted in the maxillary sinus are rarely reported. Although the causes of eruption of a tooth into the maxillary sinus are unclear, some clinical conditions are suspected to be responsible, such as developmental disturbances (cleft palate), displacement of teeth by trauma, interventions or cyst, infection, genetic factors, crowding, and dense bone. Most cases of ectopic teeth in the maxillary sinus are asymptomatic and are occasionally diagnosed thanks to routine radiographic investigations.The aim of this article is to present and discuss the surgical management of an ectopic third molar in the roof of the maxillary sinus.

    Ectopic teeth occur because of failure of the first branchial cleft to close during development and are found mostly in young horses. Such dentigerous cysts are often located at the base of the ear, forming a notable swelling with a fistula, as it was the case with the two year old Iceland mare «Runa». In order to confirm the diagnosis, x-ray images were taken, which is also necessary to locate the ectopic tooth correctly. While operating, the whole cystic membrane should be removed and it is important to prevent adjacent nerves and blood vessels from damage. Prognosis for complete healing after removing an ectopic tooth is excellent.

    Full Text Available Ectopic neurohypophysis is an anomaly of the Pituitary gland whichmay be associated with short stature due to Growth hormone deficiency.MRI is the modality of choice in diagnosing this condition. We present acase of pituitary dwarfism and ectopic neurohypophysis with clinical andradiological findings. 21 year-old male admitted with short stature. Allhormones, except prolactin, of anterior hypophysis were low. Bright spotwas ectopically located at level of median eminence on enhanced MRI ofhypophysis and stalk of hypophysis was not observed. Ectopicneurohypophysis may be present with pituitary dwarfism. Cranial MRI maybe useful to investigate related pathologies in such cases.

    Plants offer a promising alternative for the production of foreign proteins for pharmaceutical purposes in tissues that are consumed as food and/or feed. Our long-term strategy is to develop edible vaccines against piglet diarrhoea caused by enterotoxigenic Escherichia coli (F4 ETEC) in feed plants. In this work, we isolated a gene, faeG, encoding for a major F4ac fimbrial subunit protein. Our goal was to test whether the FaeG protein, when isolated from its fimbrial background and produced in a plant cell, would retain the key properties of an oral vaccine, that is, stability in gastrointestinal conditions, binding to intestinal receptors and inhibition of the F4 ETEC attachment. For this purpose, tobacco was first transformed with a faeG construct that included a transit peptide encoding sequence to target the FaeG protein to the chloroplast. The best transgenic lines produced FaeG protein in amounts of 1% total soluble protein. The stability of the plant-produced FaeG was tested in fluids simulating piglet gastric (SGF) and intestinal (SIF) conditions. Plant-produced FaeG proved to be stable up to 2 h under these conditions. The binding and inhibition properties were tested with isolated piglet villi. These results showed that the plant-produced FaeG could bind to the receptors on the villi and subsequently inhibit F4 ETEC binding in a dose-dependent manner. Thus, the first two prerequisites for the development of an oral vaccine have been met.

    Full Text Available We report a rare case of an adult with advanced liver failure in the setting of an untreated congenital panhypopituitarism. A 32-years-old man presented with a newly onset seizure episode secondary to hypoglycemia. In the initial exploration, we found eunuchoid habitus, absence of secondary sexual characteristics, ascites, and hepatic encephalopathy. Hormonal evaluation confirmed the absence of anterior hypophyseal hormones and the liver function tests showed derangement of liver function. Magnetic Resonance Imaging (MRI showed hypoplastic adenohypophysis and ectopic posterior pituitary gland. In the approach to liver disease, no cause was identified, besides the untreated panhypopituitarism.

    Full Text Available Increase in the rates of caesarean deliveries has led to a concurrent rise in the number of caesarean scar ectopic pregnancies (CSEP. With recent advances, diagnosis can be made at an early gestational age, hence facilitating a prompt intervention. With the varied treatment options available, choosing the right one may possess a clinical dilemma. However, in a low resource setting, conventional laparotomy may be the only option feasible. A case of CSEP managed with laparotomy is presented. [Int J Reprod Contracept Obstet Gynecol 2015; 4(5.000: 1581-1584

    2012-02-01

    INTRODUCTION: Ectopic pituitary adenomas are extremely rare. We report a case of ectopic pituitary adenoma in the midline of the nasopharynx. This adenoma probably arose from the pharyngeal remnant of Rathke\\'s pouch. METHODS: We discuss a case of a lady who presented to our unit with 2 months history of dryness and sensation of lump in her throat and a long standing history of hypothyroidism. Examination of nasopharynx revealed a smooth and fluctuant midline mass. CT scan of nose and paranasal sinuses confirmed the midline mass with small defect communicating with the sphenoid sinus. An initial diagnosis of Thornwaldt\\'s cyst was made and she underwent upper aerodigestive tract endoscopy and marsupialization of the mass. Histopathological examination revealed ectopic pituitary adenoma. CONCLUSION: Ectopic pituitary adenoma is an important differential diagnosis for a midline nasopharyngeal mass. It is recommended that prior to surgical resection of midline nasopharyngeal mass biopsy is taken and MRI is performed.

    Twin ectopic pregnancy is a rare occurrence, with an estimated incidence of 1 in 20 000 spontaneous pregnancies. We describe a case of unilateral twin ectopic pregnancy in which the gravid fallopian tube showed no signs of tubal rupture despite marked tubal distension. A 25-year-old woman presented with clinical features suggestive of large right-sided tubal ectopic pregnancy. Serum β-human chorionic gonadotropin was 10 800 IU/mL. Laparotomy revealed markedly distended right fallopian tube. There was no hemoperitoneum. The tube contained twin gestational sacs. The crown-rump length of the embryos was 2 cm. The ectopic gestation was thus unique, in that despite marked tubal distension, the trophoblastic invasion was not significant to cause tubal rupture. There may be a role for medical management based on individual gestational sac size in selected cases of twin tubal pregnancy in which there is no evidence of hemoperitoneum.

    Ectopic eruption of maxillary canines can be associated with root resorption of adjacent teeth. This case report describes and discusses an interesting case of a 15-year-old girl with a Class III malocclusion and an impacted maxillary canine. Because of the unfavorable position of the ectopic canine and the severe root resorption of the maxillary left central and lateral incisors, the treatment options included extraction of the maxillary permanent canines. The mandibular first premolars were extracted to compensate for the Class III malocclusion. A panoramic radiograph taken earlier in the mixed dentition already indicated a possible eruption disturbance of the maxillary left permanent canine. The importance of early diagnosis of maxillary canine ectopic eruption is highlighted in this case report. The early identification of radiographic signs of an ectopic pathway of eruption should be followed by deciduous canine extraction to prevent canine retention and maxillary incisor root resorption.

    Full Text Available The present research provides analysis of results of preoperative examination of 680 patients with ectopic pregnancy depending on the range of surgical treatment. It has been shown that in case of progressive ectopic pregnancy the diagnostic significance of concentrations of human chorionic gonadotropin, transvaginal examination and laparos-copy depends on the duration of pregnancy. When the term of ectopic pregnancy is 3-4 weeks monitoring of p chorionic gonadotropin in blood serum (99.5%, transvaginal examination (58% and laparoscopy (78.5% are more informative. When the term of ectopic pregnancy is more than 4 weeks there is a high diagnostic value of monitoring p-subunit of chorionic gonadotropin (99.5%, transvaginal examination (68% and laparoscopy (99,5%. The research has proved that pregnancy period of 3-4 weeks is optimal for laparoscopy and other operations

    BACKGROUND: Obstructive jaundice caused by an intraductal hepatocellular carcinoma is a rare initial symptom. We report a rare case of an extrahepatic icteric type hepatocellular carcinoma. METHODS: A 75-year-old patient was admitted to our hospital because of obstructive jaundice 3 months after resection of multilocular hepatocellular carcinoma. A postoperative bile leakage was treated by placement of a decompressing stent in the common bile duct. Endoscopic retrograde choledochoscopy showed extended blood clots iflling the bile duct system and computed tomography revealed a local swelling in the common extrahepatic bile duct. The level of alpha-fetoprotein (AFP) was only slightly elevated but that of CA19-9 was dramatically increased. Cholangiography showed an intraductal iflling defect typical of a cholangiocellular carcinoma. RESULTS: Bile duct brushing cytology showed no cholangiocellular carcinoma but hepatocellular carcinoma cells in the extrahepatic bile duct. An extrahepatic bile duct resection was performed. Histological examination conifrmed the diagnosis of extrahepatic intraductal growth of hepatocellular carcinoma. CONCLUSION: Ectopic hepatocellular carcinoma is a rare but important differentially diagnosed of extrahepatic bile duct iflling defect.

  4. Ectopic folliculosebaceous units at the coronal sulcus.

    2014-12-01

    Tyson glands were described in the 17th century as modified sebaceous glands of the coronal sulcus of the penis. However, this description and other early texts supporting the existence of Tyson glands were not accompanied by illustrations. The existence of such glands has been passing through the literature without adequate graphical demonstration, which has contributed to controversial debates. Herein we present a case of a partial penectomy performed on a 65-year-old man with a squamous cell carcinoma of the penis. In this case we identified sebaceous glands as well as folliculosebaceous units in the coronal sulcus. We also comparatively examined 12 cases of partial penectomy to search for sebaceous glands or folliculosebaceous units in the coronal sulcus or the preputium. We found neither sebaceous glands nor folliculosebaceous units at the coronal sulcus or the mucosal aspect of the prepuce. We conclude that: (1) folliculosebaceous units are possible in the coronal sulcus, as the current case illustrates for the first time in literature and (2) the current case is an oddity, probably induced by the accompanying squamous cell carcinoma, and therefore it may represent an ectopic folliculosebaceous unit rather than an anatomic variation.

    Intramural pregnancy, a gestation completely surrounded by the myometrium located within the uterine wall with separation from the uterine cavity, is an extremely unusual form of pregnancy. Complications resulting from intramural pregnancy include inevitable uterine rupture with resultant hemorrhage and possible hysterectomy if diagnosis is not made early and treatment is not initiated. An asymptomatic patient was initially diagnosed with a missed abortion at approximately 6 weeks of gestation after a routine ultrasound. Suction curettage was performed approximately 1 month after the initial diagnosis. The pathology specimen failed to reveal placental villi. Ultimately, the diagnosis of intramural pregnancy was made via ultrasound and a computed tomography scan. She was treated with a single dose of systemically administered methotrexate. Over a period of 4 months, β-human chorionic gonadotropin levels trended downward; however, the intramural pregnancy failed to resolve completely, and a persistent mass remained. The intramural pregnancy was removed using the da Vinci laparoscopic procedure (Intuitive Surgical, Sunnyvale, CA). If the diagnosis of intramural ectopic pregnancy is made sufficiently early, conservative measures can be taken, which can preserve a patient's future fertility.

    A 34-year-old female presented to our clinic with a 1.5 year history of secondary amenorrhea and galactorrhea. Prolactin (PRL) level was found to be 151.89 ng/ml. Pituitary imaging was reported to be normal. An examination of the patient revealed that PRL level was still high so the dose of cabergoline was further increased and subsequently, bromocriptine was added to the treatment. There was no reduction in PRL levels in controls. A scanning was performed to look for an ectopic focus. Abdominal computerized tomography revealed a heterogenous mass lesion originating from the uterus. Octreotide scintigraphy was performed and we observed an involvement consistent with the mass in the uterus. The patient underwent abdominal total hysterectomy. PRL dropped to 0.4 ng/ml the next day after the operation. The pathology result was a low-grade malignant mesenchymal tumor. Prolactin was found to be immunohistochemically negative. However, galactorrhea disappeared postoperative and PRL levels are still low. Elevated levels of PRL, resistant to bromocriptine and cabergoline, rapidly returned to normal after hysterectomy, which obviously indicates that hyperprolactinemia was associated with the myoma of the uterus.

    Ectopic pregnancy occurs in 0.5-2% of all pregnancies. A double ectopic pregnancy is very rare and has the incidence of 1 in 725 ectopic pregnancies. We describe a case of a 30-year-old patient with double ectopic pregnancy located in tubas in spontaneous cycle--diagnosed and treated at the Gynecology and Obstetrics Hospital in Walbrzych. The patient had no risk factors for ectopic pregnancy. This case shows that even the diagnosis of an evident ectopic pregnancy cannot exclude the possibility of a double ectopic pregnancy.

    Ectopic infection with Paragonimus miyazakii was determined to be the cause of a subcutaneous inguinal mass in a 15-month-old, male, boar-hunting dog. On histologic examination, the mass comprised granulomatous panniculitis, intralesional adult trematodes and eggs, and lymphadenitis. Extrapulmonary paragonimosis in animals is rare. This appears to be the first report in a dog of ectopic P. miyazakii infection with mature trematodes and eggs that involved the inguinofemoral lymphocenter and surrounding subcutis.

    Endometriosis (ENDO) is a disorder in which vascularized growths of endometrial tissue occur outside the uterus. Its symptoms include reduced fertility and severe pelvic pain. Mechanisms that maintain the ectopic growths and evoke symptoms are poorly understood. One factor not yet considered is that the ectopic growths develop their own innervation. Here, we tested the hypothesis that the growths develop both an autonomic and a sensory innervation. We used a rat model of surgically induced EN...

    The classic symptoms of ectopic pregnancy are secondary amenorrhoea, abdominal pain and vaginal haemorrhage, with a clinical picture of varying acuteness. It is among the commonest causes of maternal mortality during the first three months of pregnancy In the majority of cases (95%) the pregnancy is tubal, but other sites are possible (cervical, corneal, ovarian, peritoneal). In the treatment of sterility or medically assisted reproduction, the risk of ectopic pregnancy should be borne in min...

    The purpose of this study was to investigate the diagnostic aspects, contributing conditions, and predictive key factors associated with ectopic eruption of maxillary second molars. This retrospective study evaluated the study models, lateral cephalographs, and panoramic radiographs of 40 adult subjects (20 men, 20 women) with bilateral ectopic eruption and 40 subjects (20 men, 20 women) with normal eruption of the maxillary second molars. Studied variables were analyzed statistically by independent t-tests, univariate and multivariate logistic regression analysis, followed by receiver-operating characteristic analysis. Tooth widths of bilateral lateral incisors, canines, and premolars were wider in the ectopic group, which resulted in greater arch lengths. The ANB angle and maxillary tuberosity distance (PTV-M1, PTV-M2) were smaller in the ectopic group. The long axes of the maxillary molars showed significant distal inclination in the ectopic group. The multivariate logistic regression analysis showed that three key factors-arch length, ANB angle, and PTV-M1 distance-were significantly associated with ectopic eruption of the second molars. The area under the curve (AUC) was the largest for the combination of the three key factors with an AUC greater than 0.75. PTV-M1 alone was the single factor that showed the strongest association with ectopic eruption (AUC = 0.7363). An increase in arch length, decrease in ANB angle, and decrease in maxillary tuberosity distance to the distal aspect of the maxillary first molar (PTV-M1) were the most predictive factors associated with ectopic eruption of maxillary second molars.

    The diagnosis of Cushing disease is based on endocrinological pa-rameters, with no single test being specific. In some patients, dynamic thin-slice sellar magnetic resonance imaging fails to detect a pituitary tumor. The purpose of this study is to investigate the role of ectopic pituitary adenoma in this situation. In a retrospective chart review, 5 patients (6%) with ectopic adenomas were identified in 83 consecutive patients undergoing transsphenoidal surgery for adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas by 1 surgeon. In all 5 patients (all female, 32-41 years of age), an exclusively extrasellar ACTH-secreting adenoma was excised. Three adenomas were located in the cavernous sinus, 1 in the sphenoid sinus, and 1 in the ethmoidal cells. Histologically, none of the tumors showed signs of aggressiveness. Three of the 5 adenomas specifically expressed somatostatin receptor 5. In 4 patients with Cushing disease, postoperative remission was obtained, with 1 recurrence after 14 months. In the patient with Nelson syndrome, ACTH decreased from >800 to ectopic adenoma (positive for somatostatin receptor 5) in the ethmoidal cells turned out to be positive on gallium 68 DOTATATE positron emission tomography/computed tomography. The incidence of primarily ectopic ACTH-secreting adenomas in this series was 6%. In cases of negative MRI findings, an ectopic ACTH-secreting adenoma should be taken into account. 68 Ga DOTATATE positron emission tomography/computed tomography may identify ectopic pituitary adenomas. Hypophysectomy should always be avoided in primary surgery for CD.

    Historically, ectopic pregnancy was a life-threatening condition where diagnosis was possible only at post mortem or laparotomy and maternal mortality was up to 90%. The evolution in the management of ectopic pregnancy has meant that diagnosis can be made using non-invasive techniques with an aim to identify the ectopic gestation before tubal rupture. This enables health care professionals to offer management options that consider not only maternal mortality, but morbidity and fertility outcomes as well. In spite of this, diagnostic techniques and management options are not without limitations. Research is currently focused on new tests with a single diagnostic capability, diagnostic and treatment algorithms and safe methods of triaging patients. This article aims to review the current literature on the diagnosis and management of ectopic pregnancy and to formulate a pathway to help individualise care and achieve the best possible outcome.

    Thyroid cancer is very common, but skull ectopic thyroid cancer has not been reported in 50 years of literatures in foreign countries. There are only four cases of the skull ectopic thyroid cancer reported in more than 30 years of domestic literature including the cases in this report. This paper aims to investigate the clinical characteristics and possible molecular mechanisms of this rare disease. Five keywords of "thyroid gland", "ectopic thyroid", "thyroid cancer", "ectopic thyroid cancer" and "metastatic thyroid cancer" were included and 50 years of literatures in the PubMed-MEDLINE and Wanfang database were reviewed. By combining the test data of 2 cases of surgical patient tissue microarray specimens-molecular immunology pathology, the possible molecular mechanisms were analyzed and molecular regulation network diagram was drawn. The skull ectopic thyroid cancer has not been reported in 50 years of literatures in foreign countries and there are only four cases of the skull ectopic thyroid cancer reported in more than 30 years of domestic literature including the cases in this report. The molecular expressions of skull ectopic thyroid cancer, orthotopic thyroid cancer, and metastatic thyroid cancer were not the same: (I) AKT (P=0.012, 0.002) and mTOR (P=0.002, 0.004) were highly expressed in the skull ectopic thyroid cancer; (II) BRAF (P=0.029, 0.014) and ERK (P=0.002, 0.001) were highly expressed in orthotopic thyroid cancer; (III) MMP-9 (P=0.023, 0.016) was highly expressed in metastatic thyroid cancer. According to the molecular information base, the PI3K is predicted to be a key crossing gene of the above three signaling pathways, which showed no significant differences in these three thyroid cancers (P=0.692, 0.388, 0.227), but PI3K has regulation roles in the three signaling pathways of Akt/mTOR, MAPK, and NF-κB. PI3K gene is an important starting gene of thyroid cancers. After the canceration starts, due to the fact that the local microenvironments of

    Ectopic parathyroid glands result from aberrant migration during early stages of development and lack of successful identification may lead to lack of success in parathyroid surgery. They constitute a common etiology of persistent or recurrent hyperparathyroidism, when they are missed at initial diagnosis. Their prevalence is about 2-43% in anatomical series and up to 16% and 14% in patients with primary and secondary hyperparathyroidism, respectively. Ectopic inferior parathyroids are most frequently found in the anterior mediastinum, in association with the thymus or the thyroid gland, while the most common position for ectopic superior parathyroids is the tracheoesophageal groove and retroesophageal region. Neck ultrasound and 99mTc Sestamibi scan are first-line imaging modalities, although with low sensitivity and specificity. However, their combination with modern techniques, such as single photon emission computed tomography (SPECT) alone or in combination with CT (SPECT/CT) increases their diagnostic accuracy. Fine needle-aspiration cytology of a lesion suspicious for parathyroid tissue and measurement of parathyroid hormone (PTH) in the aspired material further assist to the successful preoperative localization of ectopic glands. Common sites for surgical investigation are the upper thyroid pole and the upper vascular thyroid stalk behind the hypopharynx and cervical esophagus for the superior parathyroids, and the carotid artery bifurcation and the thymic tongue, for the inferior parathyroids. Radioguided minimally invasive parathyroidectomy after successful localization, assisted by rapid PTH measurement postoperatively, significantly improves surgical outcomes in patients with ectopic parathyroid adenomas.

    Full Text Available Cornual ectopic gestation is one of the causes of “Maternal near miss” cases. In the modern era of IVF treatments and better imaging techniques, more number of cases of cornual ectopic pregnancies is being diagnosed and treated both by conservative and radical methods. Here, we report a case of a recurrent cornual ectopic pregnancy in the early second trimester, which was managed by hysterectomy due to uncontrolled haemorrhage. Thirty five year old Mrs. S, Gravida 4, para2, with one previous ectopic pregnancy presented to the obstetric casualty with acute abdominal pain at 15 weeks +2 days of gestation. On vaginal examination, there was right fornicial fullness and both the fornices were tender. Cervical motion tenderness was also present. On review of her previous records, dating scan done at 8 to 9 weeks showed normal intrauterine pregnancy. An emergency scan was carried out which revealed an empty uterine cavity with gestational sac measuring 3.6×4.4×4.6 cms seen outside the uterus just above the fundus with absent cardiac activity. There was evidence of haemoperitoneum, therefore she was diagnosed with recurrent ruptured ectopic pregnancy.

    Presentation of hydatidiform mole as tubal ectopic pregnancy is very rare. These patients usually present with ectopic pregnancy and are later diagnosed with hydatidiform mole on the basis of histological examination following surgery. We present the case of a 32-year-old female who presented with abdominal pain and vaginal bleed since 2 days of presentation. She was vitally stable. There was mild tenderness in hypogastrium and left iliac fossa. Pelvic examination showed mild bleeding per vaginum and fullness in both fornices. The patient was suspected of having an ectopic pregnancy. Ultrasonography of pelvis revealed fluid in cul-de-sac and a sac like mass of 1.8 cm attached to the left ovary. On laparotomy, there was a left sided tubal ectopic pregnancy and subsequently left salpingectomy was done. Histopathology of the tissue sample showed features of partial hydatidiform mole. Ectopic pregnancy can present as hydatidiform mole in rare cases for which histological examination of the tissue is required to establish the diagnosis.

    Full Text Available Introduction: Ectopic tooth eruption may result owing to one of 3 processes: developmentalDisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. In rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. When the maxillary sinus is invaded, symptoms usually occur late in the process.   Case report: A 17 years old boy referred to department of Otolaryngology, Head and Neck Surgery of university of medical sciences, Tabriz_Iran in 2010 with chronic recurrent mucoprulent discharge from retromollar trigone , posterior to right superior alveolar ridge. CT scan revealed a dense mass resembling tooth, obstructing sinus ostium with homogenous opacity with ring enhancement, occupying whole sinus and expanding all walls. A Caldwell Luke approach in combination with endoscopy was selected.   Discussions: In the present patient, removal of ectopic tooth resolved the symptoms completely, the fistula obstructed and discharges discontinued. An ectopic tooth is a rare entity obstructing sinus ostium. The etiology of ectopic eruption has not yet been completely clarified, but many theories have been suggested,including trauma, infection, developmental anomalies and pathologic conditions, such as dentigerous cysts. In summary, although the ectopic teeth is rare but it would be assumed in presence of unilateral symptoms of sinonasal cavity. Therefore in peristant unilateral sinonasal symptoms we should complete examining of this site to rule out rare causes of these symptoms.

    2017-01-01

    Full Text Available Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1–3% of all ectopic thyroid tissue is located in the lateral neck. This entity may represent the only functional thyroid tissue in the body. Malignant transformation of ectopic thyroid is uncommon; but even rarer is the development of papillary carcinoma on it. We present a case of a 33-year-old man with an incidental lateral neck mass diagnosed after a motor vehicle accident. Total thyroidectomy and lymph node resection were completed without evidence of papillary thyroid carcinoma. Malignant transformation of heterotopic thyroid tissue was the final diagnosis. The possibility of an ectopic thyroid cancer should be considered in the differential diagnosis of a pathological mass in the neck. The uniqueness of this case strives in the rarity that the thyroid gland was free of malignancy, despite ectopic tissue being positive for thyroid carcinoma. Management strategies, including performance of total thyroidectomy, neck dissection, and treatment with radioiodine, should be based on individualized risk assessment.

  5. Ectopic Pregnancy After Plan B Emergency Contraceptive Use.

    Pregnancy outcomes after emergency contraceptive use has been debated over time, but review of the literature includes mechanisms by which these medications may increase the chance of an ectopic pregnancy. Such cases are infrequently reported, and many emergency providers may not readily consider this possibility when treating patients. This is a case presentation of ectopic pregnancy in a patient who had recently used Plan B (levonorgestrel) emergency contraceptive. She presented with abdominal pain and vaginal spotting, and was evaluated by serum testing and pelvic ultrasound. She was discovered to have a right adnexal pregnancy. She was treated initially with methotrexate, though she ultimately required surgery for definitive treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report aims to bring a unique clinical case to the attention of emergency providers. The goal is to review research on the topic of levonorgestrel use and the incidence of ectopic pregnancies. The mechanism of action of this emergency contraceptive is addressed, and though no definite causal relationship is known between levonorgestrel and ectopic pregnancies, there is a pharmacologic explanation for how this event may occur after use of this medication. Ultimately, the emergency provider will be reminded of the importance of educating the patient on the possible outcomes after its use, including failure of an emergency contraceptive and the potential of ectopic pregnancy.

    Full Text Available Background: Tubal sterilization is the permanent and effective contraception method. This can be performed at any time, but at least half are performed in conjunction with cesarean or vaginal delivery and are termed puerperal. The most complication after tubal ligation is ectopic pregnancy. Ectopic pregnancy is the leading cause of maternal death in first trimester.Case presentation: We present a 33 years old woman gravida5, para4, all normal vaginal delivery, presented with complaints of delayed menstrual period, pelvic pain and spotting. She underwent tubal ligation for two times. For the first time she had puerperal Pomeroy tubal sterilization after third child delivery. Intra uterine pregnancy occurred three years later. One day after vaginal delivery of fourth child, she underwent post partum tubal ligation with the Parkland method. Tubal pregnancy occurred nine months later. Physical examination identified acute abdomen. Pelvic ultrasound showed no gestational sac in uterine cavity. The sac with fetal pole was in right adnexa. Beta-HCG was 2840mIU/ml. She underwent laparotomy. Surgical management included salpingectomy with cornual resection in both sides. The surgery identified Ectopic pregnancy.Conclusion: Any symptoms of pregnancy in a woman after tubal ligation must be investigated; an ectopic pregnancy should be excluded. Ectopic pregnancy must be considered, in any woman with lower abdominal pain, missed period and vaginal bleed-ing. Conception after tubal sterilization can be explained by fistula formation and re-canalization of fallopian tube.

    An ectopic pregnancy is the implantation and development of the ovum fertilized outside the endometrial cavity. Its incidence has increased in the last 30 years, and although its morbimortality has decreased, it is still the first cause of mortality in the first trimester of the pregnancy. Early suspicion is important, particularly in women of fertile age and with risk factors indicative of an extrauterine gestation. The symptomatology is usually amenorrhea, abdominal pain, metrorrhagia, general pregnancy symptoms, and even syncope and shock. The diagnosis of ectopic pregnancy is based on the clinical information, analytical results on mother blood and urine, ultrasound examination, transvaginal culdocentesis, laparoscopic or laparotomic inspection, and a histological study. The treatment can be surgical (salpingostomy or salpingectomy), medical (methotrexate) or expectant, depending on the factors of the ectopic pregnancy: early diagnosis, presence of acute complications, clinical condition of the patient, etc.

    Cushing syndrome due to endogenous hypercortisolism may cause significant morbidity and mortality. The source of excess cortisol may be adrenal, pituitary, or ectopic. Ectopic Cushing syndrome is sometimes difficult to localize on conventional imaging like CT and MRI. After performing a multilevel thoracoabdominal imaging with CT, the evidence regarding the use of radiotracers for PET imaging is unclear due to significant molecular and etiological heterogeneity of potential causes of ectopic Cushing's syndrome. In our systematic review of literature, it appears that GalLium-based (Ga68) somatostatin receptor analogs have better sensitivity in diagnosis of bronchial carcinoids causing Cushing syndrome and FDG PET appears superior for small-cell lung cancers and other aggressive tumors. Further large-scale studies are needed to identify the best PET tracer for this condition.

    Full Text Available Supernumerary breast or polymastia is a well-documented anomaly of the breast and commonly presents along the embryonic milk line extending between the axilla and groin. Reported incidence of accessory breast is 0.4-6% in females. During 2 years period, we encountered only two cases out of twenty cases of axillary lumps. We present one case of fibroadenoma in ectopic breast tissue (EBT in axilla. Ectopic breast denotes breast tissue at more than two pectoral regions, which is mostly benign but at times can be malignant. EBT is at a greater risk of malignancy. Fibroadenoma of ectopic axillary breast tissue (EBT is quiet rare, but should always be kept in mind for differential diagnosis of an axillary mass.

    The centromere is a specific chromosomal locus that organizes the assembly of the kinetochore. It plays a fundamental role in accurate chromosome segregation. In most eukaryotic organisms, each chromosome contains a single centromere the position and function of which are epigenetically specified. Occasionally, centromeres form at ectopic loci, which can be detrimental to the cell. However, the mechanisms that protect the cell against ectopic centromeres (neocentromeres) remain poorly understood. Centromere protein-A (CENP-A), a centromere-specific histone 3 (H3) variant, is found in all centromeres and is indispensable for centromere function. Here we report that the overexpression of CENP-ACnp1 in fission yeast results in the assembly of CENP-ACnp1 at noncentromeric chromatin during mitosis and meiosis. The noncentromeric CENP-A preferentially assembles near heterochromatin and is capable of recruiting kinetochore components. Consistent with this, cells overexpressing CENP-ACnp1 exhibit severe chromosome missegregation and spindle microtubule disorganization. In addition, pulse induction of CENP-ACnp1 overexpression reveals that ectopic CENP-A chromatin can persist for multiple generations. Intriguingly, ectopic assembly of CENP-Acnp1 is suppressed by overexpression of histone H3 or H4. Finally, we demonstrate that deletion of the N-terminal domain of CENP-Acnp1 results in an increase in the number of ectopic CENP-A sites and provide evidence that the N-terminal domain of CENP-A prevents CENP-A assembly at ectopic loci via the ubiquitin-dependent proteolysis. These studies expand our current understanding of how noncentromeric chromatin is protected from mistakenly assembling CENP-A. PMID:25298518

    Hormonal contraceptive pills containing 750 microgram levonorgestrel are the most commonly used postcoital contraceptive method because of their high efficacy and fewer side effects. Emergency contraceptive pills containing levonorgestrel present their effects by several mechanisms, including delayed tubal transport of the ovum. A delay of tubal transportation of an ovum is also one of the possible etiologic factors of tubal ectopic pregnancies. There are limited data on the risk of ectopic pregnancy following levonorgestrel treatment as an emergency contraception. Here, a case of tubal pregnancy associated with the use of levonorgestrel containing emergency contraceptive pills has been presented along with discussion of the relevant literature. PMID:24591928

    Pulmonary agenesis is a rare embryological defect, usually unilateral, and is associated with skeletal, cardiovascular, and other anomalies. A 22-month-old girl was admitted to our clinic with recurrent pulmonary infections. A chest X-ray and multidetector computed tomography (MDCT) revealed pulmonary agenesis with dextrocardia, sternal defects, and a right pelvic ectopic kidney. We report on the first known case of right-sided pulmonary agenesis combined with isolated dextrocardia, sternal defects, and an ectopic kidney. The importance of MDCT for the diagnosis of pulmonary agenesis and associated other anomalies is demonstrated.

    Summary: In order to study the angiogenesis in endometriosis, the samples of eutopic and ectopic en-dometria from patients with endometriosis were quantitatively analyzed by color morphometric imagesystem (CMIS) for vascular surface area, and by examining endometrial blood vessel for microvesseldensity (MVD). The results showed that within each menstrual phase the vascular surface area andMVD were significantly higher in ectopic endometria with endometriosis than those in eutopic en-dometria with endometriosis or normal endometrium (P<0. 05). It is concluded that angiogenesismight be involved in the development of endometriosis.

    By combining X-ray crystallography and modelling, we describe here the atomic structure of distinct adhesive moieties of FimA, the shaft fimbrillin of Actinomyces type 2 fimbriae, which uniquely mediates the receptor-dependent intercellular interactions between Actinomyces and oral streptococci as well as host cells during the development of oral biofilms. The FimA adhesin is built with three IgG-like domains, each of which harbours an intramolecular isopeptide bond, previously described in several Gram-positive pilins. Genetic and biochemical studies demonstrate that although these isopeptide bonds are dispensable for fimbrial assembly, cell-cell interactions and biofilm formation, they contribute significantly to the proteolytic stability of FimA. Remarkably, FimA harbours two autonomous adhesive modules, which structurally resemble the Staphylococcus aureus Cna B domain. Each isolated module can bind the plasma glycoprotein asialofetuin as well as the polysaccharide receptors present on the surface of oral streptococci and epithelial cells. Thus, FimA should serve as an excellent paradigm for the development of therapeutic strategies and elucidating the precise molecular mechanisms underlying the interactions between cellular receptors and Gram-positive fimbriae.

    Full Text Available Enterotoxigenic Escherichia coli (ETEC strains cause diarrhoeal disease in piglets and calves in Indonesia. These strains possess two virulence factors namely attachment and enterotoxin antigens . These factors could be detected phenotypically and genetically. Haemolytic Escherichia coli (E coli isolates possessing K88 fimbrial antigen associated with 0-group 108 and 149. They were positive for K88 gene and demonstrated their ability to produce heat labile enterotoxin (LT and genetically were all positive for LT gene . Seventeen isolates ofE coli K88 which associated with 0-group 149 were positive forSTb gene, other O-serotypes were negative . Ten isolates of Ecoli K88 which associated with 0-group 108 possessed K88, K99, LT and STa genes, but negative for STb gene . However, phenotypically the K99 antigen and STa toxin were not expressed under laboratory conditions, the reason was not well understood . E. coli K99 strains isolated from calves wit h diarrhoea were all associated with 0-group 9 and produced STa toxin when tested by suckling mousse bioassay. The E. coli K99 calf isolates were all hybridized with K99 and STa gene only . It is likely that K99 gene is associated with STa gene . The DNA hybridization technique is more convenience to be used for confirmation diagnosis of colibacillosis, however, not all veterinary laboratories could perform these tests .

    Ectopic canine teeth develop displaced from their normal position. Any permanent tooth can be ectopic, and the cause may be both genetic and environmental. Orthodontic treatment is justified because ectopic canine teeth can migrate in the jaw bone and may damage the adjacent teeth roots and bone. Orthodontic treatment is also justifiable for aesthetic reasons. Diagnosis and treatment of ectopically erupting permanent maxillary canines requires timely management by the orthodontist.

    Objective To evaluate the feasibility and safety of operative laparoscopy for ectopic pregnancy with hypovolemic shock.Methods Two hundred and fifteen women with ectopic pregnancy underwent operative laparoscopy. These patients were divided into two groups. The study group included 21 patients with shock and intraperitoneal hemorrhage more than 1000 mL,and control group included 194 patients, hemodyramically stable, with blood loss less than 1000 mL. Clinical data of perioperative periods in two groups were retrospectively analyzed.Results All patients were tubal pregnancies. The occurrence rate of tubal rupture was higher in study group than in control group (80.95% vs. 15.98%, P < 0.001). Intraabdominal blood loss was significantly higher in study group than in control group (1900 mL vs. 300 mL, P < 0.001), and autologous blood transfusions were given to 95.24% and 9.3% of patients in study and control group, respectively (P < 0.001). Laparoscopic salpingectomy was performed on 85.7 % and 50.5%of patients in study and control group (P < 0.001). The operative time was somewhat longer in study group than that in control group (60 minutes vs. 45 minutes), but with no significant difference. All patients had no perioperative complications.Conclusion Operative laparoscopy in patients with hopovolemic shock can be safely and effectively performed by experienced laparoscopists with the aid of optimal anesthesia, advanced cardiovascular monitoring, and autologous blood transfusion.

    Full Text Available Objective  To discuss the relative and independent risk factors in ectopic pregnancy. Methods  The clinical data of 870 patients with ectopic pregnancy, admitted from 2005 to 2012, were retrospectively analyzed, with 800 cases of normal pregnancy serving as control. Monofactorial correlation analysis was used to analyze the related risk factor, and logistic regression analysis was used to analyze the independent risk factor. Results  Pelvic adhesion, previous operation, cesarean section delivery, number of pregnancy, artificial abortion, medical abortion, in vitrofertilization and embryo replacement (IVF-ER, and placement of intrauterine device (IUD are the risk factors of ectopic pregnancy, pelvic adhesion, artificial abortion, operation, number of pregnancies and IUD are the independent risk factors, and pelvic adhesion is the major risk factor. Conclusion  Avoidance of unexpected pregnancy as possible, reduction of the number of artificial abortion, prevention and treatment of genital duct inflammation, and standardization of pelvic operation may reduce the incidence of ectopic pregnancy.

  4. Diffuse Peritonitis due to Perforated Gastric Ectopic Pancreas

    Full Text Available Ectopic pancreas is frequently found in the gastrointestinal tract. Lesions comprise well-developed and normally organized pancreatic tissue outside the pancreas, without anatomic or vascular connections with the true pancreas. Most patients with ectopic pancreas are asymptomatic or exhibit nonspecific symptoms. A 68-year-old Japanese woman had been experiencing intermittent pain in the right upper abdomen. Suddenly, the abdominal pain changed to intense pain in the right flank of the abdomen 2 days later. On initial medical examination, the abdomen exhibited rebound tenderness and distension. The results of laboratory tests revealed increased inflammatory reaction. Abdominal computed tomography showed free air and ascites on the surface of the liver and elevated levels of adipose tissue around the antrum and pylorus of the stomach. Perforation of the upper gastrointestinal tract was diagnosed and we performed urgent surgery. The site of perforation, whose size was 25 mm, was the lesser curvature of the antrum of the stomach. Since it was not possible to perform omentopexy, we performed extensive gastric resection. The reconstruction was a Billroth II operation. Microscopic analysis revealed pancreatic tissue within the ulceration, showing islets of Langerhans, acini, and ducts; the lesion was diagnosed as type I using Heinrich’s criteria. The postoperative course was uneventful. The patient was discharged on day 13 and remains clinically healthy. Gastric perforation due to ectopic pancreas has been reported in 2 cases, including our patient, and is extremely rare. Once gastric perforation has been diagnosed, the presence of ectopic pancreas might be considered.

    1984-12-01

    When a DNA fragment containing a marker gene was ligated to random chromosomal fragments of Streptococcus pneumoniae and used to transform a recipient strain lacking that gene, the gene was integrated at various locations in the chromosome. Such ectopic integration was demonstrated for the malM gene, and its molecular basis was analyzed with defined donor molecules consisting of ligated fragments containing the malM and sul genes of S. pneumoniae. In a recipient strain deleted in the mal region of its chromosome, these constructs gave Mal/sup +/ transformants in which the malM and sul genes were now linked, with malM located between duplicate sul segments. Ectopic integration was unstable under nonselective conditions; mal(sul) ectopic insertions were lost at a rate of 0.05% per generation. Several possible mechanisms of ectopic integration were examined. The donor molecule is most likely to be a circular form of ligated homologous and nonhomologous fragments that, after entry into the cell, undergoes circular synapsis with the recipient chromosome at the site of homology, followed by repair and additive integration.

    Endometriosis (ENDO) is a disorder in which vascularized growths of endometrial tissue occur outside the uterus. Its symptoms include reduced fertility and severe pelvic pain. Mechanisms that maintain the ectopic growths and evoke symptoms are poorly understood. One factor not yet considered is that the ectopic growths develop their own innervation. Here, we tested the hypothesis that the growths develop both an autonomic and a sensory innervation. We used a rat model of surgically induced ENDO whose growths mimic those in women. Furthermore, similar to women with ENDO, such rats exhibit reduced fertility and increased pelvic nociception. The ENDO was induced by autotransplanting, on mesenteric cascade arteries, small pieces of uterus that formed vascularized cysts. The cysts and healthy uterus were harvested from proestrous rats and immunostained using the pan-neuronal marker PGP9.5 and specific markers for calcitonin gene-related peptide (CGRP) (sensory C and A delta fibers), substance P (SP) (sensory C and A delta fibers) and vesicular monoamine transporter (sympathetic fibers). Cysts (like the uterus) were robustly innervated, with many PGP9.5-stained neurites accompanying blood vessels and extending into nearby luminal epithelial layers. CGRP-, SP-, and vesicular monoamine transporter-immunostained neurites also were observed, with CGRP and SP neurites extending the furthest into the cyst lining. These results demonstrate that ectopic endometrial growths develop an autonomic and sensory innervation. This innervation could contribute not only to symptoms associated with ENDO but also to maintenance of the ectopic growths.

    Ectopic pregnancy is commonly located in the fallopian tube. Nevertheless, two unusual types of ectopic pregnancy, intramural pregnancy and rudimentary horn pregnancy, seriously threaten maternal life. The diagnosis and treatment of these unusual implantation sites present a clinical challenge. In this study, we illustrated the two unusual types of ectopic pregnancy and summarized the current data regarding diagnosis and optimal treatment from our experience.

    Ectopic pregnancy occurs when implantation of the blastocyst takes place in a site other than the endometrium of the uterine cavity. Uncommon implantation sites of ectopic pregnancy include the cervix, interstitial segment of the fallopian tube, scar from a prior cesarean delivery, uterine myometrium, ovary, and peritoneal cavity. Heterotopic and twin ectopic pregnancies are other rare manifestations. Ultrasonography (US) plays a central role in diagnosis of uncommon ectopic pregnancies. US features of an interstitial ectopic pregnancy include an echogenic interstitial line and abnormal bulging of the myometrial contour. A gestational sac that is located below the internal os of the cervix and that contains an embryo with a fetal heartbeat is indicative of a cervical ectopic pregnancy. In a cesarean scar ectopic pregnancy, the gestational sac is implanted in the anterior lower uterine segment at the site of the cesarean scar, with thinning of the myometrium seen anterior to the gestational sac. An intramural gestational sac implants in the uterine myometrium, separate from the uterine cavity and fallopian tubes. In an ovarian ectopic pregnancy, a gestational sac with a thick hyperechoic circumferential rim is located in or on the ovarian parenchyma. An intraperitoneal gestational sac is present in an abdominal ectopic pregnancy. Intra- and extrauterine gestational sacs are seen in a heterotopic pregnancy. Two adnexal heartbeats suggest a live twin ectopic pregnancy. Recognition of the specific US features will help radiologists diagnose these uncommon types of ectopic pregnancy.

    Recently we have described the molecular cloning of the genetic determinant coding for the S-fimbrial adhesin (Sfa), a sialic acid-recognizing pilus frequently found among extraintestinal Escherichia coli isolates. Fimbriae from the resulting Sfa+ E. coli K-12 clone were isolated, and an Sfa-specific antiserum was prepared. Western blots indicate that S fimbriae isolated from different uropathogenic and meningitis-associated E. coli strains, including O83:K1 isolates, were serologically related. The Sfa-specific antibodies did not cross-react with P fimbriae, but did cross-react with F1C fimbriae. Furthermore the sfa+ recombinant DNAs and some cloned sfa-flanking regions were used as probes in Southern experiments. Chromosomal DNAs isolated from O18:K1 and O83:K1 meningitis strains with and without S fimbriae and from uropathogenic O6:K+ strains were hybridized against these sfa-specific probes. Only one copy of the sfa determinant was identified on the chromosome of these strains. No sfa-specific sequences were observed on the chromosome of E. coli K-12 strains and an O7:K1 isolate. With the exception of small alterations in the sfa-coding region the genetic determinants for S fimbriae were identical in uropathogenic O6:K+ and meningitis O18:K1 and O83:K1 strains. The sfa determinant was also detected on the chromosome of K1 isolates with an Sfa-negative phenotype, and specific cross-hybridization signals were visible after blotting against F1C-specific DNA. In addition homology among the different strains was observed in the sfa-flanking regions.

  19. Transcriptional activation of the mrkA promoter of the Klebsiella pneumoniae type 3 fimbrial operon by the c-di-GMP-dependent MrkH protein.

    Directory of Open Access Journals (Sweden)

    Ji Yang

    Full Text Available The Gram-negative bacterial pathogen Klebsiella pneumoniae forms biofilms to facilitate colonization of biotic and abiotic surfaces. The formation of biofilms by K. pneumoniae requires the expression of type 3 fimbriae: elongate proteinaceous filaments extruded by a chaperone-usher system in the bacterial outer membrane. The expression of the mrkABCDF cluster that encodes this fimbrial system is strongly positively regulated by MrkH, a transcriptional activator that responds to the second messenger, c-di-GMP. In this study, we analyzed the mechanism by which the MrkH protein activates transcriptional initiation from the mrkA promoter. A mutational analysis supported by electrophoretic mobility shift assays demonstrated that a 12-bp palindromic sequence (the MrkH box centered at -78.5 is the binding site of MrkH. Deletion of half a turn, but not a full turn, of DNA located between the MrkH box and the mrkA promoter destroyed the ability of MrkH to activate mrkA transcription. In addition, a 10-bp AT-rich sequence (the UP element centered at -63.5 contributed significantly to MrkH-dependent mrkA transcription. In vivo analysis of rpoA mutants showed that the R265 and E273 determinants in the C-terminal domain of RNA polymerase α subunit are needed for MrkH-mediated activation of mrkA transcription. Furthermore, results from mutagenesis of the mrkH gene suggest that the N-terminal region of the protein is involved in transcriptional activation. Taken together, our results suggest that MrkH activates mrkA expression by interacting directly with RNA polymerase, to overcome the inefficient transcriptional initiation caused by the presence of defective core promoter elements.

    2011-01-01

    Full Text Available Ectopic ureter is one of the most common urinary tract anomalies. We, herein, present a case of a giant ureter with ectopic orifice, mimicking pelvic organ prolapse, which is the first in the literature. A 59-year-old female patient presenting with frequently recurrent urinary tract infection had grade 3 pelvic organ prolapse. On examination, the organ producing the appearance of prolapse was found to be a right ureter of giant size and was obstructed by a large stone at the distal segment. The proximal end of the ureter ended blindly. After exploration, the stone was removed, the ureter was detached from the urethra, and the lumen was tied off and cut 5 cm proximally. At 6 months postoperatively, the patient is being followed up without any clinical problems. In such cases with nonfunctioning renal segment draining proximally, the chance of cure can be obtained without a need for a comprehensive intervention such as total abdominal ureterectomy.

  1. Total Laparoscopic Conservative Surgery for an Intramural Ectopic Pregnancy

    Full Text Available A 38-year-old woman, gravida 3, para 1 with a history of a left salpingectomy for an ectopic pregnancy was admitted for treatment of a presumed ectopic pregnancy. Transvaginal sonography revealed an ill-defined gestational sac and fetal heart beat within the fundal myometrium adjacent to the left cornua. Laparoscopy was performed for a suspected left cornual pregnancy or intramural pregnancy. A cystic mass 3 cm in diameter was visible within the fundal myometrium. Total laparoscopic removal of the gestational sac was performed, and the uterus was preserved. Pathologic evaluation of the excised mass demonstrated chorionic villi involving the myometrium. In the literature, only one other case describing the laparoscopic removal of an intramural pregnancy has been reported. However, in the prior report, the patient still required hysterectomy after conservative surgery. Therefore, this is the first report of the successful treatment of an intramural pregnancy exclusively with laparoscopy.

    Interstitial pregnancy is defined as any gestation that develops in the uterine portion of the fallopian tubes lateral to the round ligament. Interstitial pregnancies account for 2-4% of all ectopic pregnancies and have been reported to have an associated 2% to 2.5% maternal mortality rate. The traditional treatment for interstitial pregnancy using surgical cornual resection may cause infertility or uterine rupture in subsequent pregnancies. Recently, the early identification of intact interstitial pregnancy has been made possible in many cases with high resolution transvaginal ultrasound as well as more sensitive assays for betahuman chorionic gonadotropin ({beta}-hCG). The treatment includes: hysteroscopic transcervical currettage, local and systemic methotrexate (MTX) therapy and prostaglandin or potassium chloride injection of the ectopic mass under sonographic guidance. We describe a case of successful treatment of interstitial pregnancy using uterine artery embolization, after failure of methotrexate treatment.

    Pulpectomy in primary teeth is a common technique that preserves teeth in the oral environment and maintains or recovers periapical tissues to a healthy condition. This article describes the ectopic eruption of permanent incisors whose primary predecessors underwent pulpectomy using ZOE filler paste. In a group of 135 teeth that received pulpectomy therapy due to caries, 10 primary maxillary incisors had overretention and were followed for at least 3.5 years (mean time of 4.2 years), both clinically and radiographically, until the permanent teeth erupted. The proposed treatment included extraction of the overretained primary incisors based on permanent successor eruption chronology and contralateral eruption. Seven permanent teeth erupted ectopically. Autocorrection of the permanent tooth positions was observed in five cases. It can be concluded that periodic clinical and radiographic assessments are essential to verify radicular and filling paste resorptions and to avoid overretention and any subsequent malocclusion.

Although it is considered a clinically benign neoplasm, necrosis is encountered in 25% of cases and it can invade adjacent bone structures. Aims : To establish clinical, radiological and histopathological features of ectopic sphenoid sinus pituitary adenoma. Material and methods: Analysis of three cases: two females and one man, aged 61-70. Results : One patient presented with a unilateral hearing loss, the other two with headache and vertigo. They all suffered from type 2 diabetes mellitus. Neurological examination revealed no abnormality. Radiological imaging showed a sphenoid sinus space-occupying soft-tissue lesion with bone erosion in 2 cases and empty sella in 2 patients whereas one had a normal pituitary gland. All were operated on via the transnasal approach. Total resection was achieved in one patient and subtotal in two; in two cases we observed intact sellar dura and in one intact sellar floor. Histopathology showed immunoreactivity for synaptophysin in all cases and cytokeratin in two. The Ki-67 index was less than 2%. Immunohistochemical staining demonstrated growth hormone cells in all cases whereas prolactin and adrenocorticotropin in two. The patients were discharged home in good condition with no neurological deficits. Conclusions : Ectopic sphenoid sinus pituitary adenoma should always be considered in differential diagnosis of sphenoid sinus lesion in the elderly, especially in coexistence with empty sella or type 2 diabetes mellitus. Since ectopic sphenoid sinus pituitary adenoma is a benign lesion, surgical removal is an effective treatment.

    Full Text Available BACKGROUND: Congenital hypothyroidism from thyroid dysgenesis (CHTD is predominantly a sporadic disease characterized by defects in the differentiation, migration or growth of thyroid tissue. Of these defects, incomplete migration resulting in ectopic thyroid tissue is the most common (up to 80%. Germinal mutations in the thyroid-related transcription factors NKX2.1, FOXE1, PAX-8, and NKX2.5 have been identified in only 3% of patients with sporadic CHTD. Moreover, a survey of monozygotic twins yielded a discordance rate of 92%, suggesting that somatic events, genetic or epigenetic, probably play an important role in the etiology of CHTD. METHODOLOGY/PRINCIPAL FINDINGS: To assess the role of somatic genetic or epigenetic processes in CHTD, we analyzed gene expression, genome-wide methylation, and structural genome variations in normal versus ectopic thyroid tissue. In total, 1011 genes were more than two-fold induced or repressed. Expression array was validated by quantitative real-time RT-PCR for 100 genes. After correction for differences in thyroid activation state, 19 genes were exclusively associated with thyroid ectopy, among which genes involved in embryonic development (e.g. TXNIP and in the Wnt pathway (e.g. SFRP2 and FRZB were observed. None of the thyroid related transcription factors (FOXE1, HHEX, NKX2.1, NKX2.5 showed decreased expression, whereas PAX8 expression was associated with thyroid activation state. Finally, the expression profile was independent of promoter and CpG island methylation and of structural genome variations. CONCLUSIONS/SIGNIFICANCE: This is the first integrative molecular analysis of ectopic thyroid tissue. Ectopic thyroids show a differential gene expression compared to that of normal thyroids, although molecular basis could not be defined. Replication of this pilot study on a larger cohort could lead to unraveling the elusive cause of defective thyroid migration during embryogenesis.

    PurposeTo address technical feasibility and clinical outcome of transcatheter embolotherapy with N-butyl cyanoacrylate (NBCA) for bleeding ectopic varices.MethodsThe institutional review board approved this retrospective study and waived informed consent. From January 2004 to June 2013, a total of 12 consecutive patients received transcatheter embolotherapy using NBCA for bleeding ectopic varices in our institute. Clinical and radiologic features of the endovascular procedures were comprehensively reviewed.ResultsPreprocedural computed tomography images revealed ectopic varices in the jejunum (n = 7), stoma (n = 2), rectum (n = 2), and duodenum (n = 1). The 12 procedures consisted of solitary embolotherapy (n = 8) and embolotherapy with portal decompression (main portal vein stenting in 3, transjugular intrahepatic portosystemic shunt in 1). With regard to vascular access, percutaneous transhepatic access (n = 7), transsplenic access (n = 4), and transjugular intrahepatic portosystemic shunt tract (n = 1) were used. There was no failure in either the embolotherapy or the vascular accesses (technical success rate, 100 %). Two patients died within 1 month from the procedure from preexisting fatal medical conditions. Only one patient, with a large varix that had been partially embolized by using coils and NBCA, underwent rebleeding 5.5 months after the procedure. The patient was retreated with NBCA and did not undergo any bleeding afterward for a follow-up period of 2.5 months. The remaining nine patients did not experience rebleeding during the follow-up periods (range 1.5–33.2 months).ConclusionTranscatheter embolotherapy using NBCA can be a useful option for bleeding ectopic varices.

    Fibroadenoma of an accessory breast is a rare disease. The clinical significance lies in the fact that a number of cystic, inflammatory, neoplastic diseases similar to those of a normal breast have been reported in accessory breasts as well. Vigilant self-assessment and complete clinical examination are always encouraged to detect earliest malignancy in the axilla. We report two cases of ectopic breast fibroadenoma with the relevant literature.

    Ectopic pancreas (EP) is the relatively uncommon presence of pancreatic tissue outside the normal location of the pancreas. This condition is usually asymptomatic and rarely complicated by pancreatitis and malignant transformation. A few cases of neoplastic phenomena that developed from EP into the duodenal wall are described in the literature. Herein we report a case of gastric outlet obstruction due to adenocarcinoma arising from EP of the duodenal wall. The patient underwent a Whipple's procedure and had...

    Ectopic lymphoid tissues (ELT) can be found in multiple sclerosis (MS) and other organ-specific inflammatory conditions. Whether ELT in the meninges of central nervous system (CNS) autoimmune disease exhibit local germinal center (GC) activity remains unknown. In an experimental autoimmune encephalomyelitis model of CNS autoimmunity, we found activation-induced cytidine deaminase, a GC-defining enzyme, in meningeal ELT (mELT) densely populated by B and T cells. To determine GC activity in mEL...

    The purpose of this article is to review key clinical issues and imaging features of unusual pregnancy implantations. Examples from different imaging modalities are provided to increase interpreting physicians' familiarity with the appearance and potential complications of unusual ectopic, cesarean scar, heterotopic, and rudimentary horn pregnancies. Abnormal pregnancy implantations are life-threatening. Interpreting physicians' familiarity with the appearance of unusual pregnancy implantations is critical for early identification and initiation of appropriate therapy.

    We report the case of an ectopic pituitary adenoma in a 65-year-old man with an empty sella who initially presented with right ptosis and eyelid edema and headache. Neuroimaging studies revealed a large tumoral process at the height of the clivus, with partial destruction of surrounding bone structure. He underwent transphenoidal surgery and histopathologic examination, including immunohistochemical studies, revealed a prolactin-producing pituitary adenoma. A careful review of the literature was done.

    Esthesioneuroblastoma is a rare malignant neoplasm of oflactory neuroepithelium and usually located at the olfactory cleft at superior nasal cavity. Ectopic localization of esthesioneuroblastoma is even rarer and usually posed with a diagnostic dilemma and delay in the diagnosis and management, We report a rare case of ectopic esthesioneuroblastoma of the sphenoclivus with the presentation of intermittent unilateral epistaxis, intermittent intractable headache without anosmia. Nasal endoscopy findings showed a pulsatile mass at the anterior face of the sphenoid sinus with extension posteriorly towards the clivus region and occupying the floor of the sphenoid sinus. Endonasal transclival endoscopic excision of tumour was performed which involved otorhinolaryngology surgeon and neurosurgeon with intraoperative navigation imaging and frozen section. The histopathological findings was esthesioneuroblastoma. Due to its rarity and unusual presentation, the diagnosis of ectopic esthesioneuroblastoma is difficult and can be misdiagnosed with the other type of malignancy. Therefore, the histopathological result is important in confirming the type of tumour and can lead to the next step of management.

    While chronic pain is a main symptom in endometriosis, the underlying mechanisms and effective therapy remain elusive. We developed an animal model enabling the exploration of ectopic endometrium as a source of endometriosis pain. Rats were surgically implanted with autologous uterus in the gastrocnemius muscle. Within two weeks, visual inspection revealed the presence of a reddish-brown fluid-filled cystic structure at the implant site. Histology demonstrated cystic glandular structures with stromal invasion of the muscle. Immunohistochemical studies of these lesions revealed the presence of markers for nociceptor nerve fibers and neuronal sprouting. Fourteen days after surgery rats exhibited persistent mechanical hyperalgesia at the site of the ectopic endometrial lesion. Intralesional, but not contralateral, injection of progesterone was dose-dependently antihyperalgesic. Systemic administration of leuprolide also produced antihyperalgesia. In vivo electrophysiological recordings from sensory neurons innervating the lesion revealed a significant increase in their response to sustained mechanical stimulation. These results are consistent with clinical and pathological findings observed in patients with endometriosis, compatible with the ectopic endometrium as a source of pain. This model of endometriosis allows mechanistic exploration at the lesion site facilitating our understanding of endometriosis pain.

    Full Text Available The present case report demonstrates a laparoscopic approach to treat interstitial cornual pregnancy in emergency. Interstitial ectopic pregnancy develops in the uterine portion of the fallopian tube which accounts for 2–4% of all ectopic pregnancies and has the potential to cause life-threatening hemorrhage at rupture. The mortality rate for a woman diagnosed with such a pregnancy is 2–2.5%. Diagnosis of interstitial pregnancy is made by ultrasound. In this case a 32 year-old woman, Gravida 0 Parity 0 Living 0 Ectopic 1, presented to the emergency obstetrical room complaining acute abdominal pain. There was a history of 10 weeks of pregnancy but no pelvic ultrasound scan was performed before the access. A transvaginal ultrasound scan immediately performed demonstrated a gestational sac with viable fetus in the right interstitial region. Moreover there was an ultrasound evidence of hemoperitoneum. She was transferred to the operating room and an emergency laparoscopy surgery was performed. The postoperative course was uneventful and the patient was discharged two days after the surgery. Interstitial pregnancies present a difficult management problem with no absolute standard of care in literature. Laparoscopic technique is under study with favorable results. For our personal point of view a treatment via laparoscopy could be performed both in elective and in emergency cases.

    Full Text Available An ectopic kidney is a common developmental anomaly of the urinary system. However, the thoracic kidney (TK is the rarest state form of an aberrant kidney. The aim of this case report is defining the symptoms in TK diagnosis and constructing a treatment model will promote the best outcomes. These patients come to the physician with the various symptoms, and they could be diagnosed incidentally. In our case, we describe 40 years female patient with severe respiratory problems and upper back pain. In the pulmonary clinic, suspected mass was diagnosed with chest X-ray, and computerized tomography detected nontraumatic nonhernia associated, a truly ectopic TK. Moreover, the thoracic surgeon and urologist team decided to exploration and reconstructed the right ectopic kidney. The 1st month of the control of patient symptoms was disappeared. Overall, TK should be kept in mind in the differential diagnosis of thoracic tumors. Surgical exploration and reconstruction should be thought in patients who have severe respiratory symptoms.

    Full Text Available Bronchopulmonary carcinoids are rare pulmonary neoplasms although they account for most cases of ectopic ACTH syndromes. When feasible, the mainstay treatment is surgical resection of the tumor. We report the case of a 52-year-old woman with signs and symptoms suggestive of hypercortisolism for 12 months, admitted to our department because of community acquired pneumonia. Blood hormone analysis showed increased levels of ACTH and urinary free cortisol and nonsuppressibility to high- and low-dose dexamethasone tests. Pituitary MRI showed no lesion and no central-to-peripheral ACTH gradient was present in bilateral inferior petrosal sinus sampling. CRH stimulation test suggested an ectopic ACTH source. Thoracic CT scan revealed a nodular region measuring 12 mm located in the inferior lingular lobule of the left superior lung with negative uptake by 18-FDG-PET scan and negative SRS. The patient was successfully treated with an atypical lung resection and histology revealed an atypical bronchial carcinoid tumor with positive ACTH immunoreactivity. This was an interesting case because the patient was admitted due to pneumonia that may have been associated with her untreated and chronic hypercortisolism and a challenging case of ectopic ACTH syndrome due to conflicting results on the diagnostic exams.

    2012-01-01

    Full Text Available Cushing’s syndrome (CS is a rare but severe clinical condition represented by an excessive endogenous cortisol secretion and hence excess circulating free cortisol, characterized by loss of the normal feedback regulation and circadian rhythm of the hypothalamic-pituitary axis due to inappropriate secretion of ACTH from a pituitary tumor (Cushing’s disease, CD or an ectopic source (ectopic ACTH secretion, EAS. The remaining causes (20% are ACTH independent. As soon as the diagnosis is established, the therapeutic goal is the removal of the tumor. Whenever surgery is not curative, management of patients with CS requires a major effort to control hypercortisolemia and associated symptoms. A multidisciplinary approach that includes endocrinologists, neurosurgeons, oncologists, and radiotherapists should be adopted. This paper will focus on traditional and novel medical therapy for aggressive ACTH-dependent CS. Several drugs are able to reduce cortisol levels. Their mechanism of action involves blocking adrenal steroidogenesis (ketoconazole, metyrapone, aminoglutethimide, mitotane, etomidate or inhibiting the peripheral action of cortisol through blocking its receptors (mifepristone “RU-486”. Other drugs include centrally acting agents (dopamine agonists, somatostatin receptor agonists, retinoic acid, peroxisome proliferator-activated receptor γ “PPAR-γ” ligands and novel chemotherapeutic agents (temozolomide and tyrosine kinase inhibitors which have a significant activity against aggressive pituitary or ectopic tumors.

    Chronic ectopic pregnancy is an uncommon form of tubal pregnancy manifested as a pelvic mass with minimal symptoms and a low or absent titer of human chorionic gonadotropin. For this reason, most of the reported cases have been diagnosed only after explorative laparotomy. The value of Doppler ultrasonography for preoperative diagnosis of this entity has not yet been established. We report on a 36-year-old patient who was admitted for intermittent right lower quadrant abdominal pain of 3 months' duration, and a right adnexal mass found on pelvic examination. On Doppler ultrasonography, a right complex adnexal mass was demonstrated, characterized by extensive external vascularization, aberrant vessels and arteriovenous shunting, but with no internal blood flow. Explorative laparotomy revealed a right tubal mass adherent to the omentum, and covered by numerous enlarged and tortuous blood vessels originating in the omentum. Pathological examination of the mass revealed a chronic ectopic pregnancy. The possible contribution of Doppler-specific characteristics for the diagnosis of chronic ectopic pregnancy is described and discussed.

    Full Text Available Ectopic hepatocellular carcinoma (HCC is a very rare clinical entity that is defined as HCC arising from extrahepatic liver tissue. This report presents a case of ectopic multiple HCC arising in the abdominal cavity. A 42-year-old otherwise healthy male presented with liver dysfunction at a general health checkup. Both HCV antibody and hepatitis B surface antigen were negative. Laboratory examination showed elevations in serum alpha-fetoprotein and PIVKA-II. Ultrasonography and computed tomography revealed multiple nodular lesions in the abdominal cavity with ascites without a possible primary tumor. Exploratory laparoscopy was performed, which revealed bloody ascites and multiple brown nodular tumors measuring approximately 10 mm in size that were disseminated on the perineum and mesentery. A postoperative PET-CT scan was performed but it did not reveal any evidence of a tumor in the liver. The tumors resected from the peritoneum were diagnosed as HCC. The present case of HCC was thought to have possibly developed from ectopic liver on the peritoneum or mesentery.

    Bilateral tubal ectopic pregnancies are a rare subset of ectopic pregnancy that can pose a diagnostic dilemma for clinicians. There is no distinct clinical presentation for bilateral tubal ectopic pregnancies, although they are typically associated with assistive reproductive techniques. In addition, there is no single diagnostic feature to help clinicians delineate bilateral tubal ectopic pregnancies from other types of ectopic pregnancy prior to passing the discriminatory zone (such as heterotopic pregnancy or twin ectopic [two gestational sacs in one tube]). Diagnosis is typically made via direct visualization intraoperatively and therefore treatment is usually surgical. We present a case of spontaneous bilateral tubal ectopic pregnancies diagnosed 7 days apart via transvaginal ultrasound. The patient presented to the emergency department with pelvic pain on the contralateral side of her previously diagnosed ectopic pregnancy and vaginal spotting. Bilateral adnexal masses were visualized on ultrasound and her serum beta-human chorionic gonadotropin level had a 5.9% decline from day 4 to day 7 after methotrexate administration 7 days prior; gynecology was consulted. The patient was successfully treated with an additional dose of intramuscular methotrexate without any complications. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The implications of this case suggest that diagnosis of bilateral tubal ectopic pregnancies requires clinicians to have a high level of suspicion in any pregnant female with a suspected or known ectopic pregnancy who presents with pelvic pain regardless of prior diagnosis or treatment.

  1. Frequency of nonallelic homologous recombination is correlated with length of homology: evidence that ectopic synapsis precedes ectopic crossing-over.

    Genomic disorders constitute a class of diseases that are associated with DNA rearrangements resulting from region-specific genome instability, that is, genome architecture incites genome instability. Nonallelic homologous recombination (NAHR) or crossing-over in meiosis between sequences that are not in allelic positions (i.e., paralogous sequences) can result in recurrent deletions or duplications causing genomic disorders. Previous studies of NAHR have focused on description of the phenomenon, but it remains unclear how NAHR occurs during meiosis and what factors determine its frequency. Here we assembled two patient cohorts with reciprocal genomic disorders; deletion associated Smith-Magenis syndrome and duplication associated Potocki-Lupski syndrome. By assessing the full spectrum of rearrangement types from the two cohorts, we find that complex rearrangements (those with more than one breakpoint) are more prevalent in copy-number gains (17.7%) than in copy-number losses (2.3%); an observation that supports a role for replicative mechanisms in complex rearrangement formation. Interestingly, for NAHR-mediated recurrent rearrangements, we show that crossover frequency is positively associated with the flanking low-copy repeat (LCR) length and inversely influenced by the inter-LCR distance. To explain this, we propose that the probability of ectopic chromosome synapsis increases with increased LCR length, and that ectopic synapsis is a necessary precursor to ectopic crossing-over.

    Full Text Available Static broth culture favors Salmonella enterica subsp. enterica serovar Typhimurium to produce type 1 fimbriae, while solid agar inhibits its expression. A transposon inserted in stbC, which would encode an usher for Stb fimbriae of a non-flagellar Salmonella enterica subsp. enterica serovar Typhimurium LB5010 strain, conferred it to agglutinate yeast cells on both cultures. RT-PCR revealed that the expression of the fimbrial subunit gene fimA, and fimZ, a regulatory gene of fimA, were both increased in the stbC mutant when grown on LB agar; fimW, a repressor gene of fimA, exhibited lower expression. Flagella were observed in the stbC mutant and this phenotype was correlated with the motile phenotype. Microarray data and RT-PCR indicated that the expression of three genes, motA, motB, and cheM, was enhanced in the stbC mutant. The stbC mutant was resistant to several antibiotics, consistent with the finding that expression of yhcQ and ramA was enhanced. A complementation test revealed that transforming a recombinant plasmid possessing the stbC restored the mannose-sensitive agglutination phenotype to the stbC mutant much as that in the parental Salmonella enterica subsp. enterica serovar Typhimurium LB5010 strain, indicating the possibility of an interplay of different fimbrial systems in coordinating their expression.

    A rare case of ectopic pancreas in the ampulla of Vater presented with obstructive jaundice. Ectopic pancreas is a common congenital disorder which is referred to as pancreatic rest. The incidence in autopsy series varies from 1 to 2% (range 0.55 to 13%). Most common site of ectopic pancreatic tissue is the stomach, although it can be found anywhere in the foregut and the proximal midgut. Ectopic pancreatic tissue in the ampulla of Vater is a very rare condition. Searching in the literature, using the terms "ectopic pancreas" and "Ampulla of Vater", we found only 10 records. The authors report on a rare case of a 69 years old female with ectopic pancreas in the ampulla of Vater, presented with painless obstructive jaundice, and the diagnostic and therapeutic strategy that followed.

    Full Text Available Objective. To report a case of successful laparoscopic management of a left ruptured tubal pregnancy in the setting of an ipsilateral ectopic pelvic kidney. Method. Case report was prepared at Wayne State University/Detroit Medical Center. The patient is a young woman gravida 2 para 0 in her twenties who presented with severe abdominal pain and vaginal bleeding. She had a plateaued beta HCG and ultrasonographic findings suggestive of ectopic left tubal pregnancy along with an ectopic ipsilateral pelvic kidney. The IRB approval is not needed, as this is a case report. The informed consent could not be obtained, as the patient was not reachable. Result. Multiple intraperitoneal adhesions, left ruptured ampullary ectopic pregnancy and left retroperitoneal pelvic mass consistent with ipsilateral ectopic pelvic kidney. Conclusion. Laparoscopic management of tubal pregnancy can be safely performed in the setting of an ipsilateral ectopic pelvic kidney.

    Our objective is to present a short series of four rare cases of ectopic olfactory neuroblastoma. Our methods present four case reports of ectopic olfactory neuroblastoma and a review of the literature for management and treatment of this disease. The results indicate short case series reports of ectopic olfactory neuroblastoma arising from the anterior ethmoidal sinuses, the nasopharynx, the lateral nasal wall and the floor of the nose. The discussion focuses on likely origins of ectopic olfactory neuroblastoma, its clinical features and management. We conclude that ectopic olfactory neuroblastoma is a rare disease. Treatment principles are the same for non-ectopic disease and guided by extension into adjacent structures such as the orbit or anterior cranial fossa and usually involves surgery with or without adjuvant radiotherapy.

    A noticeable genomic feature of many piliated Gram-positive bacterial species is the presence of more than one pilus-encoding operon. Paradigmatically, the gut-adapted Lactobacillus rhamnosus GG strain contains two different fimbrial operons in its genome. However, whereas one of these operons (called spaCBA) is encoding for the functionally mucus-/collagen-binding SpaCBA pilus, for the other operon (called spaFED) any native expression of the SpaFED-called pili is still the subject of some uncertainty. Irrespective of such considerations, we decided it would be of relevance or interest to decipher the gross structure of this pilus type, and as well assess its functional capabilities for cellular adhesion and immunostimulation. For this, and by following the approach we had used previously to explicate the immuno-properties of SpaCBA pili, we constructed nisin-inducible expression clones producing either wild-type or SpaF pilin-deleted surface-assembled L. rhamnosus GG SpaFED pili on Lactococcus lactis cells. Using these piliated lactococcal constructs, we found that the pilin-polymerized architecture of a recombinant-produced SpaFED pilus coincides with sequence-based functional predictions of the related pilins, and in fact is prototypical of those other sortase-dependent pilus-like structures thus far characterized for piliated Gram-positive bacteria. Moreover, we confirmed that among the different pilin subunits encompassing spaFED operon-encoded pili, the SpaF pilin is a main adhesion determinant, and when present in the assembled structure can mediate pilus binding to mucus, certain extracellular matrix proteins, and different gut epithelial cell lines. However, somewhat unexpectedly, when recombinant SpaFED pili are surface-attached, we found that they could not potentiate the existing lactococcal cell-induced immune responses so elicited from intestinal- and immune-related cells, but rather instead, they could dampen them. Accordingly, we have now provided

    Full Text Available Posterior pituitary ectopia refers to an absent normal posterior pituitary bright spot within the sella with ectopic bright signal at another site (such as the median eminence on a weighted magnetic resonance. We describe two children with idiopathic anterior hypopituitarism who showed an ectopic posterior pituitary and absent pituitary stalk on imaging. We emphasize the association of the absent pituitary stalk in ectopic pituitary gland and low growth hormone levels.

    Homologous recombination is increased during meiosis between DNA sequences at the same chromosomal position (allelic recombination) and at different chromosomal positions (ectopic recombination). Recombination hotspots are important elements in controlling meiotic allelic recombination. We have used artificially dispersed copies of the ade6 gene in Schizosaccharomyces pombe to study hotspot activity in meiotic ectopic recombination. Ectopic recombination was reduced 10-1000-fold relative to a...

    Dual ectopic lingual and sublingual thyroid gland is an extraordinarily rare condition. We present 1 patient with subclinical hypothyroidism. The clinical examination revealed that the thyroid gland was not palpable in its usual cervical location, whereas ultrasonography confirmed an empty thyroid bed without any ectopic thyroid tissue in the rest of the neck. The final diagnosis of dual ectopic lingual and sublingual thyroid was established by ultrasound examination through the mouth floor and confirmed by scintigraphy and CT thereafter.

  14. Embryonic miRNA profiles of normal and ectopic pregnancies.

    Full Text Available Our objective was to investigate the miRNA profile of embryonic tissues in ectopic pregnancies (EPs and controlled abortions (voluntary termination of pregnancy; VTOP. Twenty-three patients suffering from tubal EP and twenty-nine patients with a normal ongoing pregnancy scheduled for a VTOP were recruited. Embryonic tissue samples were analyzed by miRNA microarray and further validated by real time PCR. Microarray studies showed that four miRNAs were differentially downregulated (hsa-mir-196b, hsa-mir-30a, hsa-mir-873, and hsa-mir-337-3p and three upregulated (hsa-mir-1288, hsa-mir-451, and hsa-mir-223 in EP compared to control tissue samples. Hsa-miR-196, hsa-miR-223, and hsa-miR-451 were further validated by real time PCR in a wider population of EP and control samples. We also performed a computational analysis to identify the gene targets and pathways which might be modulated by these three differentially expressed miRNAs. The most significant pathways found were the mucin type O-glycan biosynthesis and the ECM-receptor-interaction pathways. We also checked that the dysregulation of these three miRNAs was able to alter the expression of the gene targets in the embryonic tissues included in these pathways such as GALNT13 and ITGA2 genes. In conclusion, analysis of miRNAs in ectopic and eutopic embryonic tissues shows different expression patterns that could modify pathways which are critical for correct implantation, providing new insights into the understanding of ectopic implantation in humans.

    An ectopic tooth in the nasal cavity is a rare phenomenon, especially on the inferior turbinate. In most of the reported cases, no etiological explanation of the intranasal teeth has been suggested or found. In children, intranasal ectopic teeth are usually associated with cleft lip and alveolus. Here, we report a rare case of a pediatric patient with unilateral nasal obstruction due to an intranasal ectopic tooth originating from the inferior turbinate without any facial and dental deformities. This case is unique due to the unusual location of the ectopic tooth and its presentation in a child without facial and dental deformities.

    Ectopic teeth erupt into regions other than the natural position or should be impacted in unusual location. Etiology of these teeth includes trauma, infection, and developmental diseases; however, in many cases, it is idiopathic. In addition, dentigerous cysts that are related with ectopic teeth may also affect adjacent anatomic regions. The occurrence of ophthalmic complications related with ectopic teeth is a rare situation. In this article, we aimed to present a patient who had a blurred vision thought that resulted from the dentigerous cyst associated with the ectopic third molar in the maxillary sinus roof.

    Full Text Available The storage of triglyceride (TG droplets in nonadipose tissues is called ectopic fat storage. Ectopic fat is associated with insulin resistance and type 2 diabetes mellitus (T2DM. Not the triglycerides per se but the accumulation of intermediates of lipid metabolism in organs, such as the liver, skeletal muscle, and heart seem to disrupt metabolic processes and impair organ function. We describe the mechanisms of ectopic fat depositions in the liver, skeletal muscle, and in and around the heart and the consequences for each organs function. In addition, we systematically reviewed the literature for the effects of diet-induced weight loss and exercise on ectopic fat depositions.

    Olfactory receptors (ORs) are mainly distributed in olfactory neurons and play a key role in detecting volatile odorants, eventually resulting in the production of smell perception. Recently, it is also reported that ORs are expressed in non-olfactory tissues including heart, lung, sperm, skin, and cancerous tissues. Interestingly, ectopic ORs are associated with the development of diseases in non-olfactory tissues. For instance, ectopic ORs initiate the hypoxic ventilatory responses and maintain the oxygen homeostasis of breathing in the carotid body when oxygen levels decline. Ectopic ORs induce glucose homeostasis in diabetes. Ectopic ORs regulate systemic blood pressure by increasing renin secretion and vasodilation. Ectopic ORs participate in the process of tumor cell proliferation, apoptosis, metastasis, and invasiveness. Ectopic ORs accelerate the occurrence of obesity, angiogenesis and wound-healing processes. Ectopic ORs affect fetal hemoglobin levels in sickle cell anemia and thalassemia. Finally, we also elaborate some ligands targeting for ORs. Obviously, the diversified function and related signal pathway of ectopic ORs may play a potential therapeutic target in non-olfactory tissues. Thus, this review focuses on the latest research results about the diversified function and therapeutic potential of ectopic ORs in non-olfactory tissues. © 2017 Wiley Periodicals, Inc.

    Full Text Available Ectopic eruption is a deviation from the normal eruption pattern, making the tooth erupt out of its normal position, and possibly causing resorption of adjacent primary teeth. A wide range of etiological factors may be responsible for ectopic eruption of the teeth, so their management depends on the correction of the established etiological factor. The present case report describes an unusual case of ectopically erupted central incisor encased within an abnormally thickened labial frenum, which was treated by orthodontic repositioning of the ectopically erupting tooth after frenectomy.

    Ectopic prostatic tissue (EPT) outside the male genitourinary tract is an unusual finding, and it is very rarely found in the rectum or around the peri-rectal region. In addition, the radiologic features of EPT are seldom reported. Also, it is difficult to differentiate EPT found in the rectal subepithelium from the other types of subepithelial tumors. We present here a unique case of EPT found in the retrorectal region, along with the radiologic findings of transrectal ultrasonography, computed tomography, and magnetic resonance imaging with their pathologic correlations.

    Tungiasis is a neglected ectoparasitism of impoverished areas in South America and sub-Saharan Africa. The sand flea Tunga spp. preferably infests the soles and the periungueal and interdigital regions of the feet. Ectopic tungiasis is rare, even in highly endemic areas. We describe a case of an indigenous patient in Peru who presented with a nodular lesion in the extensor aspect of the knee and whose biopsy was compatible with Tunga spp. This is the first documented case of knee tungiasis in an endemic country. The historical, clinical, histological, and current epidemiological aspects of tungiasis in Peru are discussed here. PMID:20519602

    Background Obesity is increasingly associated with COPD, but little is known about the prevalence of ectopic fat accumulation in COPD and whether this can possibly be associated with poor clinical outcomes and comorbidities. The Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints (ECLIPSE) substudy tested the hypothesis that COPD is associated with increased ectopic fat accumulation and that this would be associated with COPD-related outcomes and comorbidities. Methods Computed tomography (CT) images of the thorax obtained in ECLIPSE were used to quantify ectopic fat accumulation at L2–L3 (eg, cross-sectional area [CSA] of visceral adipose tissue [VAT] and muscle tissue [MT] attenuation, a reflection of muscle fat infiltration) and CSA of MT. A dose–response relationship between CSA of VAT, MT attenuation and CSA of MT and COPD-related outcomes (6-minute walking distance [6MWD], exacerbation rate, quality of life, and forced expiratory volume in 1 second [FEV1] decline) was addressed with the Cochran–Armitage trend test. Regression models were used to investigate possible relationships between CT body composition indices and comorbidities. Results From the entire ECLIPSE cohort, we identified 585 subjects with valid CT images at L2–L3 to assess body composition. CSA of VAT was increased (P<0.0001) and MT attenuation was reduced (indicating more muscle fat accumulation) in patients with COPD (P<0.002). Progressively increasing CSA of VAT was not associated with adverse clinical outcomes. The probability of exhibiting low 6MWD and accelerated FEV1 decline increased with progressively decreasing MT attenuation and CSA of MT. In COPD, the probability of having diabetes (P=0.024) and gastroesophageal reflux (P=0.0048) at baseline increased in parallel with VAT accumulation, while the predicted MT attenuation increased the probability of cardiovascular comorbidities (P=0.042). Body composition parameters did not correlate with coronary

    The presence of salivary gland tissue in the sella turcica has rarely been reported, mainly after pituitary examination at autopsy. Only five symptomatic cases have previously been described, mainly associated with Rathke's cleft cyst. We report a 17-year-old boy presenting with headaches and hyperprolactinemia. The MRI showed a 19 mm sellar mass that at surgery revealed as a cystic lesion filled with mucinous fluid. The histological examination documented the presence of ectopic salivary gland tissue in the wall of a Rathke's cleft cyst. The present report focuses on the possible pitfalls when dealing with unusual sellar lesions, and the need of increased awareness of this rare condition.

    Full Text Available Pregnancy implanted outside the endometrial cavity constitutes ectopic gestation. The reproductive performance can be poor following an ectopic pregnancy. The purpose of the study is to emphasize the importance of public awareness about the need for early reporting to hospital in doubtful cases, to analyze the risk factors for ectopic, to study the role of βHCG estimation and transvaginal sonography in early detection in order to preserve the fallopian tube by medical therapy and/or to do early elective surgery preventing emergency laparotomy and death from ectopic pregnancy. METHODOLOGY: All cases of ectopic gestations managed in a tertiary care hospital for a period of one year is reviewed, roughly around 70 cases. The objectives were to analyze demographic characteristics, risk factors, methods of diagnosis and to evaluate the protocol for ectopic management in the hospital. RESULTS: The study showed that the maximum number of ectopic was seen in the 26 - 30 age group and more commonly among multies. Maximum number of ectopic cases is seen between 5.1 to 6 weeks and 80% of the cases are seen in ≤8 weeks. 42/70 patients showed one or more risk factors like previous history of ectopic, LSCS, infertility treatment, sterilization and use of IUCD.82.9% patients presented either with pain alone or pain along with spotting/bleeding p/v. Earlier, majority of the cases were reported after tubal rupture resulting in shock, which sometimes even lead to death. In the present scenario, however, only 2 patients developed hypotension, 11 out of 70 alone required blood transfusion and none required laparotomy. Majority of cases of unruptured ectopic (83% showed <66% rise in βHCG in 48 hours. Pelvic ultrasound and serum βHCG estimation has revolutionized the diagnostic proce ss of ectopic pregnancy enabling detection in the unruptured stage itself in 50% of the cases and the rest in early stages of rupture. In most cases, medical line of management with

    In this study, we tested the hypothesis that cadmium-induced developmental toxicity was mediated via ectopic occurrence of apoptosis during embryonic development. We employed confocal microscopy to acquire images of whole-mount staining of apoptotic cells in zebrafish embryo exposed to 100 {mu}M cadmium from 5 hours post fertilisation (hpf) to 28 hpf. Three-dimensional reconstruction of the images was performed and the spatial and temporal distributions of apoptotic cells in the embryos were compared. In cadmium-treated embryos with varying degrees of gross developmental malformations, significantly higher numbers of apoptotic cells were detected with this method. In order to detect the precise locations of apoptotic cells, we performed terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL) assay in sectioned embryos. In the degenerating neural tube of cadmium-treated embryos apoptotic cells were detected, while in the healthy neural tube of the untreated controls no apoptotic cells were found. We then employed flow cytometry to investigate whether cadmium exposure would affect the dynamics of apoptosis or induce any abnormalities in cell-cycle progression. It appeared that cadmium did not induce cell-cycle arrest. The percentages of apoptotic cells did not differ in the two groups at 13, 16 or 19 hpf. At 28 hpf, however, a significantly higher percentage of apoptotic cells were found in the cadmium-treated group. Exposure to cadmium, therefore, induced ectopic apoptosis at 28 hpf without affecting the dynamics of apoptosis at earlier developmental stages. (orig.)

    2016-01-01

    Introduction: Anomalous origin of coronary arteries from opposite sinus of Valsalva is rare finding. The incidence of anomalous origination of the left coronary artery from right sinus is 0.15% and the right coronary artery from the left sinus is 0.92%. The ectopic origin of left coronary artery or right coronary artery from opposite sinus depending on pathways and considering atherosclerotic changes are manifested with different clinical significance. Case report: We report two cases, the first case the coronary angiography showed the left coronary artery arising from the right coronary sinus, presenting with proximally and distally stenosed left anterior descending artery (LAD), associated with medial and distal stenosed right coronary artery (RCA). The second case the coronary angiography revealed the right coronary artery arising from the left coronary sinus, associated with tortuous medial and distal segments of left anterior descending artery (LAD), without atherosclerotic changes. The first case successfully underwent treatment procedures based on guidelines for revascularization. Conclusion: The coronary angiography of patients with coronary ischemia determines atherosclerotic disease with possibility of the presence of coronary artery anomalies that in cases with ectopic origin from opposite sinus continues to exist as a challenge during treatment in interventional cardiology.

    Patient: Male, 41 Final Diagnosis: Olfactory neuroblastoma Symptoms: Left nasal obstruction • occasional left epistaxis • headache Medication: None Clinical Procedure: Nasal endoscopic examination • neck palpation • CT • bilateral endoscopic resection • MRI • PET-CT • postoperative radiotherapy Specialty: Otolaryngology Objective: Unusual clinical course Background: Olfactory neuroblastoma (ONB), also known as esthesioneuroblastoma, is a rare malignant head and neck cancer thought to originate from the olfactory epithelium. It typically invades contiguous structures at presentation. We report a very rare case of multifocal and ectopic ONB. Case Report: A 41-year-old man presented with left nasal obstruction and occasional left epistaxis associated with headache. Endoscopic examination of the nasal cavities and computed tomography suggested bilateral polypoid masses. Histopathological diagnosis after endoscopic resection established bilateral olfactory neuroblastoma of the ethmoid sinuses. The patient received postoperative radiotherapy. He remains free of disease 4 years after treatment. Conclusions: To the best of our knowledge this is the second documented case of multifocal ectopic olfactory neuroblastoma. Clinicians should consider ONB in the differential diagnosis of bilateral synchronous nasal and paranasal masses to avoid delayed diagnosis. Endoscopic resection of ONB could be an option in selected cases. PMID:27097989

    We evaluated the diagnostic accuracy of activin B in discriminating tubal ectopic pregnancy (tEP) from intrauterine miscarriages (IUM), and normal viable intrauterine pregnancy (IUP). We included 28 women with tEP, 31 women with IUM, and 29 normal IUP, confirmed both by clinical examination and ultrasonography. Serum activin B concentration was measured at the time of admission using the ELISA kit. The median serum activin B concentration was found to be significantly decreased in both tEP (p=0.004) and IUM (p=0.022) compared to normal IUP. When compared between tEP and IUM, activin B concentrations did not differ significantly. ROC analysis of activin B and free β-hCG demonstrated AUC of 0.722 and 0.805, respectively to discriminate tEP from viable IUP. The model including both activin B and free β-hCG improved the discriminating potential with greater AUC (0.824), and specificity (93%) than individual one. To discriminate tEP from IUM, activin B, free β-hCG and combination of both performed poorly. We conclude that serum activin B concentration is lower in tubal ectopic pregnancy, and can discriminate it from normal pregnancy with moderate accuracy. It also shows improved diagnostic potential along with free β-hCG, but cannot distinguish tEP from IUM reliably.

  16. Cushing-type ectopic pituitary adenoma with unusual pathologic features

    Directory of Open Access Journals (Sweden)

    Kristopher T. Kimmell, MD

    2014-06-01

    Full Text Available Ectopic pituitary adenomas comprise, by varying reports, approximately 1-2% of all pituitary adenomas. They are often located in the nasopharyngeal region associated with the pharyngeal pituitary. The location and pathologic features of these masses make them atypical when compared with intrasellar pituitary adenomas. A 54-year-old man presented with vertebral compression fracture and physical stigmata of Cushing’s disease. Biochemical testing confirmed hypercortisolemia responsive to high dose dexamethasone suppression. MRI of the head demonstrated an enhancing mass in the posterior aspect of the sphenoid sinus not involving the sella turcica. Endoscopic biopsy followed by resection confirmed this mass to be a pituitary adenoma with unusual pathologic features. Most notably, the tumor cells demonstrated large, eosinophilic, vacuolated cytoplasm. Immunohistochemical profile of the tumor was typical of an ACTH secreting tumor, notably with positivity for ACTH. The patient did well from his surgery. Post-operatively his serum cortisol level normalized and he remains in chemical remission one year after surgery. Ectopic pituitary adenomas are an unusual manifestation of hormonally active pituitary neoplastic disease. Their atypical clinical presentations, location, and pathologic features can make them a diagnostic challenge. Clinicians should be aware of these entities, especially when considering differential diagnosis for a mass in the sphenoid sinus and nasopharyngeal region.

    The incidence of ectopic pregnancy after IVF is increased approximately 2.5-5-fold compared with natural conceptions; however, the aetiology for this increased risk remains unclear. One proposed practice change to decrease the incidence of ectopic pregnancy is blastocyst embryo transfer on day 5 rather than cleavage-stage embryo transfer on day 3. A retrospective cohort study was conducted to compare the risk of ectopic pregnancy following fresh day-5 embryo transfer with day-3 embryo transfer among women who underwent IVF and achieved pregnancy from 1998 to 2011. There were 13,654 eligible pregnancies; 277 were ectopic. The incidence of ectopic pregnancy was 2.1% among day-3 pregnancies and 1.6% among day-5 pregnancies. The adjusted risk ratio for ectopic pregnancy from day-5 compared with day-3 transfer was 0.71 (95% confidence interval 0.46-1.10). Although this analysis included 13,654 cycles, with a two-sided significance level of 0.05, it had only 21.9% power to detect a difference between the low incidence of ectopic pregnancy among both day-3 and day-5 transfers. In conclusion, this study was not able to demonstrate a difference in the risk of ectopic pregnancy among day-3 compared with day-5 transfers.

    The child with ectopic ureterocele frequently presents a diagnostic challenge. The use of standard excretory urography combined with newer modalities, such as ultrasonography and radionuclide renal scanning, provides an orderly diagnostic approach to ectopic ureterocele. This integrated approach should ensure the highest yield in a diagnostic sense and aid in assessing upper tract function, thus, helping with the selection of the proper surgical management.

    Panelli, Danielle M; Phillips, Catherine H; Brady, Paula C

    2015-01-01

    Ectopic pregnancy is a potentially life-threatening condition occurring in 1-2 % of all pregnancies. The most common ectopic implantation site is the fallopian tube, though 10 % of ectopic pregnancies implant in the cervix, ovary, myometrium, interstitial portion of the fallopian tube, abdominal cavity or within a cesarean section scar. Diagnosis involves a combination of clinical symptoms, serology, and ultrasound. Medical management is a safe and effective option in most clinically stable patients. Patients who have failed medical management, are ineligible, or present with ruptured ectopic pregnancy or heterotopic pregnancy are most often managed with excision by laparoscopy or, less commonly, laparotomy. Management of nontubal ectopic pregnancies may involve medical or surgical treatment, or a combination, as dictated by ectopic pregnancy location and the patient's clinical stability. Following tubal ectopic pregnancy, the rate of subsequent intrauterine pregnancy is high and independent of treatment modality. This review describes the incidence, risk factors, diagnosis, and management of tubal and non-tubal ectopic and heterotopic pregnancies, and reviews the existing data regarding recurrence and future fertility.

    Does the risk of adverse outcomes at the time of ectopic pregnancy vary by race/ethnicity among women receiving Medicaid, the public health insurance program for low-income people in the USA? Among Medicaid beneficiaries with ectopic pregnancy, 11% experienced at least one complication, and women from all racial/ethnic minority groups were significantly more likely than whites to experience complications. In this population of Medicaid recipients, African American women are significantly more likely than whites to experience ectopic pregnancy, but the risk of adverse outcomes has not previously been assessed. We conducted a cross-sectional observational study of all women (n = 19 135 106) ages 15-44 enrolled in Medicaid for any amount of time during 2004-2008 who lived in one of the following 14 US states: Arizona; California; Colorado; Florida; Illinois; Indiana; Iowa; Louisiana; Massachusetts; Michigan; Minnesota; Mississippi; New York; and Texas. We analyzed Medicaid claims records for inpatient and outpatient encounters and identified ectopic pregnancies with a principal diagnosis code for ectopic pregnancy from 2004-2008. We calculated the ectopic pregnancy complication rate as the number of ectopic pregnancies with at least one complication (blood transfusion, hysterectomy, any sterilization, or length-of-stay (LOS) > 2 days) divided by the total number of ectopic pregnancies. We used Poisson regression to assess the risk of ectopic pregnancy complication by race/ethnicity. Secondary outcomes were each individual complication, and ectopic pregnancy-related death. We calculated the ectopic pregnancy mortality ratio as the number of deaths divided by live births. Ectopic pregnancy-associated complications occurred in 11% of cases. Controlling for age and state, the risk of any complication was significantly higher among women who were black (incidence risk ratio [IRR] 1.47, 95% CI 1.43-1.53, P ectopic pregnancy mortality ratio was 0.48 per 100 000 live births

    Ectopic pancreas is a rare congenital malformation with pancreatic tissue in an aberrant location and not contiguous with the main gland. Patients suffering from ectopic pancreas usually have lesions in the stomach or duodenum[1,2]. Ectopic pancreatic tissue in the gallbladder is very rare, and only several cases have been reported[3-6]. We report one case of a 33-year-old man with ectopic pancreas presenting as repeatedly colic pain in the right upper quadrant of abdomen. He was first diagnosed as recurrent cholecys titis accompanied by biliary pancreatitis, but surgical pathology proved he suffered from cholecystitis and ectopic pancreas in the gallbladder wall, and the laparoscopic cholecystectomy led to relief.

  13. Virtual cell and tissue dynamics of ectopic activation of the ventricles

    2007-03-01

    Cardiac ventricular cells and tissues are normally excitable, and are activated by propagating waves of excitation that are initiated in the specialized pacemaking region of the heart. However, isolated or repetitive activity can be initiated at abnormal (ectopic) sites in the ventricles. To trigger an endogenous ectopic beat, there must be a compact focus of cells with changed membrane excitation parameters and kinetics, which initiate activity by after-depolarizations triggered by propagating activity, or that have bifurcated into autorhythmicity. This ectopic focus needs to be large enough, and adequately coupled, to drive the surrounding tissue. We investigate the initiation of ectopic excitation in computational models of human ventricular cells triggered by after-depolarizations and by up/down regulation of specific membrane conductance systems, and the propagation and evolution of ectopic activity in homogeneous or heterogeneous and isotropic, anisotropic, or orthotropic tissues.

  14. Etiology, Classification and Management of Ectopic Eruption of Permanent First Molars.

    2016-01-01

    Ectopic eruption of a permanent tooth involves abnormal resorption of a portion or all of the adjacent primary tooth. Among the most commonly ectopically erupted teeth are the permanent first molars. Ectopically erupting molars may require intervention to allow for full eruption, or they may spontaneously self-correct and erupt into occlusion. Decisions regarding the necessity of intervention, its ideal timing, and intervention type are multifactorial. Treatment options for the ectopically erupting permanent first molar include the elastomeric separator, brass wire, pre-fabricated clip separator, custom made appliances (Humphrey appliance, Halterman appliance), or extraction of the primary molar. Early intervention when indicated can ensure proper full eruption of the permanent first molar and prevent mesial angulation, arch perimeter loss, tooth impaction and ankylosis. Two cases are described that manage ectopic eruption of the permanent first molar.

    We have investigated the capacity of a well-defined Escherichia coli fimB strain, AAEC350 (a derivative of MG1655), to express type 1 fimbriae under various growth conditions. The expression of type 1 fimbriae is phase-variable due to the inversion of a 314-bp DNA segment. Two tyrosine recombinases......, FimB and FimE, mediate the inversion of the phase switch. FimB can carry out recombination in both directions, whereas the current evidence suggests that FimE-catalyzed switching is on-to-off only. We show here that AAEC350 is in fact capable of off-to-on phase switching and type 1 fimbrial expression...

  19. Laparoscopy-Assisted Billroth I Gastrectomy for Ectopic Pancreas in the Prepyloric Region

    2012-11-01

    Full Text Available Ectopic pancreatic tissue is an uncommon developmental anomaly. The condition mostly occurs in the gastrointestinal tract and is usually asymptomatic. It rarely causes symptoms of inflammation, bleeding and perforation, and has potential for malignant change. Though it is an uncommon condition, cases of ectopic pancreas have been reported worldwide. Preoperative diagnosis of ectopic pancreas is challenging because of its nonspecific symptoms and signs. Owing to the revolution of minimally invasive surgery, submucosal tumors of the stomach can be resected by laparoscopic techniques. We have earlier reported on a case of ectopic pancreas in the stomach treated by robotics-assisted laparoscopic wedge resection. Herein, we report a case of ectopic pancreas in the prepyloric region of the stomach. A 44-year-old female presented with a two-week history of epigastralgia with radiation to the back. She received endoscopy check-up which disclosed a mass in the stomach. By endoscopic findings, a submucosal lesion in the prepyloric region with umbilical folding on the mucosa was identified. The umbilical folding on the mucosa hint the orifice of the duct of ectopic pancreas into the gastric mucosa suggestive of ectopic pancreas. Contrast-enhanced abdominal computed tomography showed a 5 cm cystic mass with heterogeneous content. To sum it up, the patient was diagnosed as ectopic pancreas in the stomach. She underwent laparoscopy-assisted antrectomy with Billroth I anastomosis (excision of the antrum and prepyloric region with reconstruction of gastrointestinal continuity by gastroduodenostomy and had an uneventful hospitalization course. The histopathology of the resected tumor demonstrated ectopic pancreatic tissue in the gastric wall. To the best of our knowledge, excision of gastric ectopic pancreas using laparoscopy-assisted antrectomy with Billroth I anastomosis has never been reported in the literature.

    Use of contraception lowers a woman's risk of experiencing an ectopic pregnancy. In the case of method failure, however, progestin-only contraceptives may be more likely to result in ectopic pregnancies than some other methods such as combined hormonal and barrier contraceptives. To describe ectopic pregnancy risk associated with use of implants and progestin-only injectable contraceptives through a systematic review of published studies. We searched electronic databases for articles in any language published through May 2015 describing studies of progestin-only injectables and implants. We also searched bibliographies and review articles for additional studies. Studies that reported any pregnancies were included in the review. Independent data extraction was performed by two authors based on predefined data fields, and where possible, we calculated the proportion of pregnancies that were ectopic and the ectopic pregnancy incidence rate per 1000 woman-years. Fifty-three studies of implants and 28 studies of injectables were identified; 79% reported pregnancy location. The proportion of ectopic pregnancy ranged from 0 to 100% with an incidence of 0-2.9 per 1000 woman-years in studies of marketed levonorgestrel implants. Studies of etonogestrel implants and the injectables, depot-medroxyprogesterone acetate and norethisterone enanthate, reported few ectopic pregnancies. Progestin-only contraceptive implants and injectables protect against ectopic pregnancy by being highly effective in preventing pregnancy overall; however, the absolute risk of ectopic pregnancy varies by type of progestin. Risk of ectopic pregnancy should not be a deterrent for use or provision of these methods. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

    2016-05-01

    Cases of Caesarean Scar Ectopic Pregnancy (CSEP) are becoming increasingly common at tertiary care hospitals because of increase in rate of CS. This condition is often complicated by life threatening bleeding, uterine rupture, which might require hysterectomy leading to permanent infertility. Management can be medical, surgical or combined depending on the clinical presentation. It includes systemic methotrexate or local uterine artery chemoembolisation, dilatation and curettage, excision of trophoblastic tissue either by laparoscopy or laparotomy with uterine repair. We report two such cases managed medically in our hospital. Both the cases presented to us were asymptomatic except amenorrhoea and were diagnosed by transvaginal sonography. First case was managed with systemic methotrexate followed by Dilatation and Curettage (D&C). Second case was managed with systemic methotrexate alone successfully.

    Ectopic hamartomatous thymoma (EHT) is an extremely rare benign tumor. EHTs are difficult to differentiate from sarcomas, especially synovial sarcomas. We encountered two cases of EHT that were referred from other hospitals because sarcoma was suspected. In these cases, fusion gene detection via polymerase chain reaction or fluorescence in situ hybridization was useful for differentiating EHT from synovial sarcoma. EHT requires accurate diagnosis before surgery to avoid excessive treatment. Both tumor location and the presence of fat inside the tumor are important imaging findings for EHT, and confirmation of spindle cells, epithelial cells, and mature adipose cells in the tumor is an important pathological finding. It is important to exclude synovial sarcoma from the differential diagnosis via fusion gene analysis. PMID:28168073

    Full Text Available Implantation of a pregnancy in a scar after Caesarean section is one of the rarest locations of ectopic pregnancies. A diagnosis and/or treatment which is too late may lead to a uterine rupture, the necessity to remove the uterus and a significant increase in morbidity among mothers. The study presents a diagnostically difficult case of a 29-year-old woman, who was diagnosed with pregnancy in its seventh week, located in a scar after a Caesarean section, with highly increased values of human chorionic gonadotropin (β-HCG concentration in blood serum. The pregnancy was removed and the wound was stitched during laparotomy, without a need to remove the uterus.

    Hypercalcemia and ectopic calcification were induced in 5 lambs by supplementing the diet with the dried leaves of the plant Cestrum diurnum, for 8 to 9 weeks. Lambs developed mineralization of blood vessels, heart, kidneys, and lungs. These tissues were examined by light and electron microscopy. In the vascular tissue there was calcification of elastic fibers in the hyperplastic intima and the media, along with mineralization of mitochondria of aortic smooth muscle cells. Myocardial cells and their mitochondria were mineralized. In the kidney, there was calcification of the epithelium of the distal convoluted tubules and collecting tubules, Bowman's capsule, and the mesangial cells of the glomeruli. In the lung, there was mineralization of the alveolar septal walls and the bronchi and bronchioles. Feeding of the calcinogenic plant to lambs caused extensive soft tissue calcification. Results of the study indicated that degeneration was the early soft tissue lesion in this plant toxicity.

    The syndrome of ectopic adrenocorticotrophin secretion (EAS) is rare and is due to excess adrenocorticotrophin (ACTH) production from a nonpituitary tumour. These tumours can be covert, where the tumours are not readily apparent, and very small making them challenging to image. It is clinically and biochemically difficult to distinguish between covert EAS and Cushing's disease. The first-line investigation in locating the source of ACTH production is computed tomography (CT). The aim of this pictorial review is to illustrate the likely covert sites and related imaging findings. We review the CT appearances of tumours resulting in covert EAS and the associated literature. The most common tumours were bronchial carcinoid tumours, which appear as small, well-defined, round or ovoid pulmonary lesions. Rarer causes included thymic carcinoids, gastrointestinal carcinoids and pancreatic neuroendocrine tumours. Awareness of the imaging characteristics will aid identification of the source of ACTH production and allow potentially curative surgical resection. (orig.)

    Enterobius vermicularis is one of the most common intestinal parasites found in humans. They commonly infest the terminal ileum and large intestine, and are usually considered an innocuous parasite that can be easily eradicated with proper treatment. However, extraintestinal migration of worms, although very rare, may lead to severe health disorders or even death. This article, reports the first fatal case of ectopic enterobiasis known to the authors, which developed in an adult patient with E. vermicularis infection, causing perforation of the large intestine and generalized bacterial peritonitis. Despite emergency laparotomy, the patient died from septic shock on the day after surgery. During pathological examination, worms were found not only in the large intestine, but also in the renal parenchyma; worm eggs were found deposited in the lungs as well.

    Optimizing effective prevention and treatment of type 2 diabetes in youth is limited by incomplete understanding of its pathophysiology and how this varies across ethnicities with high risk. The aim of this study was to examine the contribution of visceral adipose tissue (VAT), hepatic fat fraction (HFF), and pancreatic fat fraction (PFF) to prediabetes in overweight/obese African American (AA) and Latino youth. We conducted a cross-sectional study in an academic pediatric care facility. A total of 148 healthy, overweight/obese adolescents (56 AA, 92 Latino; 72 males, 76 females; age, 15.5 ± 1.2 y; BMI z-score, 2.1 ± 0.5) participated in the study. They were normal glucose tolerant (n = 106) and prediabetic (n = 42), based on fasting glucose of 100-125 mg/dL and/or 2-hour glucose of 140-199 mg/dL, and/or hemoglobin A1C 6.0-6.4%. We measured sc abdominal adipose tissue, VAT, HFF, and PFF by 3-Tesla magnetic resonance imaging and measured total body fat by dual-energy x-ray absorptiometry. Adolescents with prediabetes had 30% higher HFF (P = .001) and 31% higher PFF (P = .042), compared to those with normal glucose tolerance after controlling for age, sex, pubertal stage, ethnicity, total percentage body fat, and VAT. Logistic regression showed that PFF predicted prediabetes in AAs and HFF predicted prediabetes in Latinos, with the odds of having prediabetes increased by 66% for every 1% increase in PFF in African Americans, and increased by 22% for every 1% increase in HFF in Latinos. These data demonstrate that ectopic fat phenotypes associated with prediabetes are established by adolescence. Ethnic differences in the deposition of ectopic fat in adolescents with prediabetes may differ, with pancreatic fat in AAs, vs hepatic fat in Latino adolescents, being associated with diabetes risk.

    Full Text Available Background and objective:FAM20A gene mutations result in enamel renal syndrome (ERS associated with amelogenesis imperfecta (AI, nephrocalcinosis, gingival fibromatosis, and impaired tooth eruption. FAM20A would control the phosphorylation of enamel peptides and thus enamel mineralization. Here, we characterized the structure and chemical composition of unerupted tooth enamel from ERS patients and healthy subjects.Methods: Tooth sections were analyzed by Scanning Electron Microscopy (SEM, Energy Dispersive Spectroscopy (EDS, X-Ray Diffraction (XRD, and X-Ray Fluorescence (XRF.Results: SEM revealed that prisms were restricted to the inner-most enamel zones. The bulk of the mineralized matter covering the crown was formed by layers with varying electron-densities organized into lamellae and micronodules. Tissue porosity progressively increased at the periphery, ending with loose and unfused nanonodules also observed in the adjoining soft tissues. Thus, the enamel layer covering the dentin in all ERS patients (except a limited layer of enamel at the dentino-enamel junction displayed an ultrastructural globular pattern similar to one observed in ectopic mineralization of soft tissue, notably in the gingiva of Fam20a knockout mice. XRD analysis confirmed the existence of alterations in crystallinity and composition (vs. sound enamel. XRF identified lower levels of calcium and phosphorus in ERS enamel. Finally, EDS confirmed the reduced amount of calcium in ERS enamel, which appeared similar to dentin.Conclusion: This study suggests that, after an initial normal start to amelogenesis, the bulk of the tissue covering coronal dentin would be formed by different mechanisms based on nano- to micro-nodule aggregation. This evocated ectopic mineralization process is known to intervene in several soft tissues in FAM20A gene mutant.

    Full Text Available BACKGROUND To study the proportion of ectopic pregnancies with a history of female sterilisation and to assess the risk factors associated with post sterilisation ectopic pregnancy. MATERIALS AND METHODS This is a descriptive cross-sectional study. Cases of ectopic pregnancy that were admitted in Department of Obstetrics and Gynaecology, Kozhikode, from February 2014 to July 2015 are included in the study. Details of patient were collected and they were examined in person. Investigations were recorded and clinical findings were noted. Later outcome of cases was also recorded. Data from the study was coded and entered in MS Excel and analysed with SPSS software. RESULTS There were 372 cases of ectopic pregnancies, of which 51 had history of female sterilisation. Ectopic tubal pregnancies after tubal sterilisation accounted for 13.7% of all the ectopic pregnancies in this study. 45% cases occurred in patients less than 30 years. More than 75% cases of ectopic pregnancy in the study presented at less than 7 weeks. Abdominal pain was the main symptom with which they presented. Out of the 51 cases, more than 80% patients had undergone sterilisation by modified Pomeroy’s technique while 17.6% cases had undergone laparoscopic sterilisation. 98% of the patients had their sterilisation done before 30 years of age. 64.7% cases had undergone sterilisation from a secondary care centre while 35.5% had it from a tertiary care centre. In the present study, more than half of the cases presented (as ectopic pregnancy within 5 years after sterilisation. 15% cases had history of pelvic inflammatory disease. Bilateral near total salpingectomy was done in all cases. CONCLUSION In the present study, it is observed that ectopic pregnancies following female sterilisation are not rare. It constituted 13.7% cases of ectopic pregnancies. There may be a delay in diagnosis as there is a history of sterilisation. Absence of amenorrhoea does not rule out ectopic. Most of

    As there are no specific non-invasive markers for the diagnosis of tubal ectopic pregnancy, our objective in the present study was to explore the role of inflammatory cytokines IL-6 and IL-8 in the diagnosis of ruptured tubal ectopic pregnancy. Twenty-eight women with tubal ectopic pregnancy, 31 patients with intrauterine abortion and 29 gestational age matched women having normal intrauterine pregnancy were included in the study. Five millilitre of blood was collected at the time of admission, serum was separated and stored at -70 °C for subsequent analysis of β hCG, IL-6 and IL-8 levels. The level of IL-6 was a significant increase in the women with tubal ectopic pregnancy compared to intrauterine abortion and normal pregnancy. IL-8 levels decrease significantly in the tubal ectopic pregnancy and in intrauterine abortion patients when compared with the normal pregnancy group. At the cutoff of 26.48 pg/ml IL-6 level predicted the tubal ectopic pregnancy with moderate accuracy. Therefore, it can be concluded that measurement of IL-6 may have relevance in the diagnosis of ectopic pregnancy as a novel inflammatory serum biomarkers.

    The incidence of ectopic pregnancy after assisted reproductive technology is increased approximately 2.5-5-fold compared with natural conceptions.Strategies were used to decrease the incidence of ectopic pregnancy, but ectopic pregnancy still occurs. In the present study, women were selected with decreased ovarian reserve (defined as FSH > 10 IU/L) aged 20 to 38 years who underwent IVF-ET between 2009 and 2014. These 2,061 women were age-matched with an equal number of women with normal ovarian reserve (defined as FSH ≤ 10 IU/L). During cycles following fresh embryo transfer, 93 patients were diagnosed with ectopic pregnancy. The incidence of ectopic pregnancy in clinical pregnancies was significantly higher in the decreased ovarian reserve than in the normal ovarian reserve group (5.51% vs. 2.99%). After adjusting for confounding factors, the incidence of ectopic pregnancy was significantly associated with decreased ovarian reserve. Our results showed that decreased ovarian reserve is an independent risk factor for ectopic pregnancy after in vitro fertilization-embryo transfer.

    Full Text Available In the cerebellar molecular layer parallel fibre terminals release glutamate from both the active zone and from extrasynaptic “ectopic” sites. Ectopic release mediates transmission to the Bergmann glia that ensheathe the synapse, activating Ca2+-permeable AMPA receptors and glutamate transporters. Parallel fibre terminals exhibit several forms of presynaptic plasticity, including cAMP-dependent long-term potentiation and endocannabinoid-dependent long-term depression, but it is not known whether these presynaptic forms of long-term plasticity also influence ectopic transmission to Bergmann glia. Stimulation of parallel fibre inputs at 16 Hz evoked LTP of synaptic transmission, but LTD of ectopic transmission. Pharmacological activation of adenylyl cyclase by forskolin caused LTP at Purkinje neurons, but only transient potentiation at Bergmann glia, reinforcing the concept that ectopic sites lack the capacity to express sustained cAMP-dependent potentiation. Activation of mGluR1 caused depression of synaptic transmission via retrograde endocannabinoid signalling but had no significant effect at ectopic sites. In contrast, activation of NMDA receptors suppressed both synaptic and ectopic transmission. The results suggest that the signalling mechanisms for presynaptic LTP and retrograde depression by endocannabinoids are restricted to the active zone at parallel fibre synapses, allowing independent modulation of synaptic transmission to Purkinje neurons and ectopic transmission to Bergmann glia.

    To assess 2004-2008 ectopic pregnancy rates among Medicaid recipients in 14 states and 2000-2008 time trends in three states and to identify differences in rate by race/ethnicity. Secondary analysis of Medicaid administrative claims data. Not applicable. Women ages 15-44 enrolled in Medicaid in Arizona, California, Colorado, Florida, Illinois, Indiana, Iowa, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, New York, or Texas in 2004-2008 (n = 19,135,106) and in California, Illinois, and New York in 2000-2003. None. Number of ectopic pregnancies divided by the number of total pregnancies (spontaneous abortions, induced abortions, ectopic pregnancies, and all births). The 2004-2008 Medicaid ectopic pregnancy rate for all 14 states combined was 1.40% of all reported pregnancies. Adjusted for age, the rate was 1.47%. Ectopic pregnancy incidence was 2.3 per 1,000 woman-years. In states for which longer term data were available (California, Illinois, and New York), the rate declined significantly in 2000-2008. In all 14 states, black women were more likely to experience an ectopic pregnancy compared with whites (relative risk, 1.46; 95% confidence interval, 1.45-1.47). Ectopic pregnancy remains an important health risk for women enrolled in Medicaid. Black women are at consistently higher risk than whites.

    Ectopic pregnancy accounts for 1-2% of all pregnancies in the United States. The most common site of implantation for an ectopic pregnancy is the fallopian tube. We present the first case describing a recurrent ectopic pregnancy with a fetal heartbeat after ipsilateral salpingectomy that led to tubal rupture. The patient presented with abdominal pain approximately six weeks after her last menstrual period. Seven years prior to presentation, a laparoscopic partial right salpingectomy had been performed for a tubal ectopic pregnancy. Physical exam was significant for diffuse abdominal tenderness and guarding. Ultrasonography revealed a right tubal pregnancy with a fetal pole and a fetal heart rate that was calculated to be 108 beats per minute. Free fluid was also noted. 1.5l of hemoperitoneum was subsequently evacuated and the right fallopian tube remnant with the ectopic pregnancy was removed. Pathology of the tubal remnant showed immature chorionic villi and fetal parts. The mechanism by which a recurrent ectopic pregnancy after ipsilateral salpingectomy occurs is unclear, but is theorized to be secondary to contralateral fertilization and/or tubal recanalization that may occur due to inadequate diathermy. Physicians should be aware that ectopic pregnancies may not only occur repeatedly but may also present a typically. We recommend when performing a salpingectomy that efforts be undertaken to minimize the length of the tubal remnant and to assure adequate coagulation of tissue so as to reduce the risk of recurrence.

    Merkel cells are mechanosensitive skin cells whose production requires the basic helix-loop-helix transcription factor Atoh1. We induced ectopic Atoh1 expression in the skin of transgenic mice to determine whether Atoh1 was sufficient to create additional Merkel cells. In embryos, ectopic Atoh1 expression drove ectopic expression of the Merkel cell marker keratin 8 (K8) throughout the epidermis. Epidermal Atoh1 induction in adolescent mice similarly drove widespread K8 expression in glabrous skin of the paws, but in the whisker pads and body skin ectopic K8+ cells were confined to hair follicles and absent from interfollicular regions. Ectopic K8+ cells acquired several characteristics of mature Merkel cells in a time frame similar to that seen during postnatal development of normal Merkel cells. Although ectopic K8+ cell numbers decreased over time, small numbers of these cells remained in deep regions of body skin hair follicles at 3 months post-induction. In adult mice, greater numbers of ectopic K8+ cells were created by Atoh1 induction during anagen versus telogen and following disruption of Notch signaling by conditional deletion of Rbpj in the epidermis. Our data demonstrate that Atoh1 expression is sufficient to produce new Merkel cells in the epidermis, that epidermal cell competency to respond to Atoh1 varies by skin location, developmental age and hair cycle stage, and that the Notch pathway plays a key role in limiting epidermal cell competency to respond to Atoh1 expression.

    Foci of ectopic thyroid tissue are uncommon. Most sites of thyroid ectopia are confined to the neck region. The presence of ectopic thyroid tissue outside the migration pathway of the primitive thyroid in other locations is exceptional. Given that any disease of the thyroid gland may also affect ectopic thyroid tissue, pathologists has to recognize benign or malignant conditions that may develop in the ectopic focus. We present the case of a 32-year-old woman with ectopic thyroid parenchyma in the adrenal gland. Clinically, postoperative thyroid ultrasound echography and computed tomography scans did not reveal any thyroid tumor. The ectopic tissue was a cyst bordered by mature follicular thyroid structures and was histologically benign, without the molecular alterations associated with malignant tumors of follicular cell derivation (BRAFV600E, N-RAS, H-RAS, K-RAS). Review of the literature reveals that adrenal ectopic thyroid tissue is nearly always cystic and has distinctive pathologic features. © The Author(s) 2014.

    Approximate entropy (ApEn) and sample entropy (SampEn) are the promising techniques for extracting complex characteristics of cardiovascular variability. Ectopic beats, originating from other than the normal site, are the artefacts contributing a serious limitation to heart rate variability (HRV) analysis. The approaches like deletion and interpolation are currently in use to eliminate the bias produced by ectopic beats. In this study, normal R-R interval time series of 10 healthy and 10 acute myocardial infarction (AMI) patients were analysed by inserting artificial ectopic beats. Then the effects of ectopic beats editing by deletion, degree-zero and degree-one interpolation on ApEn and SampEn have been assessed. Ectopic beats addition (even 2%) led to reduced complexity, resulting in decreased ApEn and SampEn of both healthy and AMI patient data. This reduction has been found to be dependent on level of ectopic beats. Editing of ectopic beats by interpolation degree-one method is found to be superior to other methods.

    Ectopic pancreas, which is a kind of rare congenital disease, forms during embryonic development. It can occur throughout the whole gastrointestinal tract, but has a low tendency to develop in the wall of the small intestine. It is easy for patients with ectopic pancreases to be misdiagnosed because the symptoms are untypical and can vary. In the present study, we reported two rare cases of ectopic pancreatic tissue in the wall of the small intestine, which presented with obvious abdominal pain and distention. The laboratory tests and computed tomography (CT) scans didn't reveal any evidence of ectopic pancreas. The two patients received small intestine masses resection and intestinal anastomosis. During surgery, an intestinal mass with a diameter of 4.0 cm was found in the first patient. An intestinal mass with a diameter of 0.8 cm, jejunum perforation, and diffuse peritonitis were found in the second patient. Histological analyses of the dissected intestinal masses confirmed them as ectopic pancreatic tissue. Interestingly, for the second patient, the intestinal perforation and diffuse peritonitis were not induced by the ectopic pancreas, but by a jujube pit that was found in the perforated site of the intestine. Our study demonstrated that an ectopic pancreas should be considered in cases of untypical abdominal symptoms with intestinal masses.

    Conventional imaging modalities are limited in the assessment of complex lower urinary tract anomalies including ectopic insertion of ureters. MR urography can be useful in these situations. To share our experience with MR urography in assessing lower urinary tract anomalies and to determine its accuracy in depicting ectopic ureters. We conducted a retrospective review of all MR urography examinations done between November 2007 and March 2013 to note the presence or absence of duplex kidneys and insertion of ureters. We reviewed patient charts, surgical findings and results of other investigations including cystoscopy with retrograde ureterogram in order to establish presence or absence of ectopic ureter. This served as a reference standard against which we compared MR urography results. Of 22 MR urography examinations (3 boys, 19 girls; age range 3-16 years, mean 9.2 years) performed during the study period, 19 were performed to rule out ectopic ureters, two to assess complex anatomy and one to rule out crossing vessel in ureteropelvic junction obstruction. MR urography showed ectopic ureter in 9/19 children; one proved to be a false-positive. MR urography correctly showed normal insertion in 7/19 children. In the remaining 3/19 children distal ureter could not be seen, hence insertion was indeterminate on MR urography. One of these children had an ectopic ureter on cystoscopy and surgery. Statistical analysis showed MR urography's sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) to be 88.8-100%, 70-90%, 75-88.8% and 90-100% for the detection of ectopic ureter. MR urography is highly accurate in the assessment of ectopic ureters. In incontinent girls, MR urography should be the method of choice for depicting or ruling out ectopic ureter. (orig.)

    Ectopic breast tissue is defined as glands located outside of the breast. It can be found anywhere along the milk line extending from the axilla to the groin, and can occur in the vulva. Ectopic breast tissue should be excised because it may develop benign or malignant pathologic processes. Less than 40 cases of fibroadenoma in the vulva have been reported in the literature. We report a case of a 37-year-old woman presenting a solitary vulvar mass. The mass was excised completely, and histology demonstrated an ectopic breast fibroadenoma. This is one of the few reports on the benign pathologies of vulvar mammary glands.

    The intraperitoneal injection of polycylic aromatic hydrocarbons in young Amazon mollies induces proliferation of ectopic thyroid tissue in the spleen. The authors have surveyed untreated mollies, Poecilia formosa, and four closely related poeciliid fishes to see if ectopic thyroid tissue occurs normally in the spleen. If this were the case, it is possible that the tissue may have been stimulated to proliferate by the injected compounds. We found no instances of ectopic thyroid at any site in 50 untreated Amazon mollies examined nor in some 50 spleens dissected from other untreated fish. Splenic thyroid tissue was found in five guppies from 50 surveyed, but did not occur in other species.

    Resorption of the distal root of primary second molars is a common consequence of ectopically erupting permanent first molars. Here, we report 2 unusual cases of primary molar root resorption caused by reversible (self-correcting) ectopic eruption of premolar and canine teeth. In both cases, severe pathological resorption of the mesial roots of primary molars was detected on routine dental radiographs, and the affected molars remained asymptomatic until exfoliation. The purpose of this paper was, using 2 case studies, to highlight the possibility of primary root resorption as a sequel of self-corrected ectopic eruption in locations not frequently diagnosed or reported.

    Full Text Available An intranasal tooth (INT is an ectopic tooth erupting into the nasal cavity. It is a rare clinical entity. Ectopic and supernumerary teeth may be present in many regions of maxillofacial skeleton. Ectopic teeth maybe supernumerary, deciduous or permanent. The clinical manifestations of intranasal tooth are quite variable and they may cause a variety of symptoms and complications. Their clinical and radiographic presentations are classical, posing little challenge to the diagnostician. The identification of such teeth can be important since they have potential to cause considerable morbidity. Here, we describe a case of intranasal tooth along with possible etiopathogenesis, clinical and radiographic features, differential diagnosis, potential complications and treatment modalities.

    Extensive investigation including whole-body examinations with computed tomography and magnetic resonance imaging did not detect the suspected ectopic ACTH-producing tumour in a patient with advanced Cushing's syndrome and hypokalemic alkalosis. Gamma camera examination with technetium-99m methoxyisobutylisonitrile (MIBI) depicted the tumour, which was localized in the anterior neck and mediastinum. This was later verified by surgery. [sup 99m]Tc-MIBI is normally used for myocardial scintigraphy. Its accumulation is unspecific and merely reflects metabolic activity. Despite this, the present case shows that examination with this agent can provide important information with regard to tumour localization in a given situation, thereby serving as a complement to other imaging modalities. The current literature on [sup 99m]Tc-MIBI for tumour diagnosis is reviewed. (orig.)

    To update trends in the rates of ectopic pregnancy, to compare rates of ectopic pregnancy between commercially insured and Medicaid-insured women, and to assess the differences in rates of ectopic pregnancy by different measures of ectopic pregnancy. We analyzed data from 2002 to 2013 using the Truven Health MarketScan Commercial and Medicaid Claims Database. We limited the study population to women aged 15 to 44 years with any pregnancy in each year. Pregnancy and ectopic pregnancy were identified by clinical services with diagnostic or procedural codes. Ectopic pregnancy was measured in two ways: diagnosed and treated compared with diagnosed only; pregnancy was measured in two ways: any pregnancy compared with pregnancy with delivery. We did not observe a substantial trend in the rate of ectopic pregnancy from 2002 to 2013. The rate of diagnosed and treated ectopic pregnancy substantially increased by age: 0.29% in women aged 15 to 19 years and 0.89% in women aged 40 to 44 years among the commercially insured population and 0.23% and 0.85% among the Medicaid-insured population, respectively. The rate of ectopic pregnancy also varied by the different methodologies used to estimate rates. The rate of ectopic pregnancy is relatively low and stable for women of reproductive age in the United States. Our findings highlight that it is important to clearly define the numerator and denominator in the measure of ectopic pregnancy rates.

    Recurrent ectopic pregnancy in a remnant fallopian tube after ipsilateral salpingectomy is clinically rare. We report the extremely rare case of a third recurrent ectopic pregnancy after two previous salpingectomy procedures involving the opposite tube. A 26-year-old woman, gravida 3 para 0, experienced three ectopic pregnancies brought about by natural conception, all of which were treated surgically (right partial salpingectomy, right remnant tube resection, and left total salpingectomy). During the two salpingectomy procedures involving the right tube, the patency of the intact left tube was intraoperatively confirmed with indigo carmine. The most appropriate surgical intervention should be discussed when managing recurrent ectopic pregnancies. It might be necessary to perform total salpingectomy to reduce the risk of future recurrence on the remaining tube.

    Insulator mediated alteration in higher-order chromatin and/or nucleosome organization is an important aspect of epigenetic gene regulation. Recent studies have suggested a key role for CP190 in such processes. In this study, we analysed the effects of ectopically tethered insulator factors on chromatin structure and found that CP190 induces large-scale decondensation when targeted to a condensed lacO array in mammalian and Drosophila cells. In contrast, dCTCF alone, is unable to cause such a decondensation, however, when CP190 is present, dCTCF recruits it to the lacO array and mediates chromatin unfolding. The CP190 induced opening of chromatin may not be correlated with transcriptional activation, as binding of CP190 does not enhance luciferase activity in reporter assays. We propose that CP190 may mediate histone modification and chromatin remodelling activity to induce an open chromatin state by its direct recruitment or targeting by a DNA binding factor such as dCTCF.

    Epilepsy is a common neurologic condition which includes many women's health issues. Menstrual disorders, reproductive endocrinological disturbances, ovulatory dysfunction and infertility appear to be relatively frequent in women with epilepsy. Clinical decision making which contraceptive regimen is optimal for an individual woman with epilepsy is one of the most challenging tasks when taking care of women with epilepsy. A higher incidence of breakthrough bleeding and contraceptive failure was determined among women using antiepileptic drugs. There is the increased risk for contraceptive failure with the use of P450 3A4 enzyme-inducing antiepileptic drugs (AEDs) such as phenobarbital, carbamazepine, phenytoin, felbamate, topiramate and oxcarbazepine. Therefore, it is recommended to use noninducing AEDs, or for those who use inducing AEDs, the use of oral hormonal contraceptive pills which contained equal or more than 50 microg of estrogen, or intrauterine devices. The aim of the article is to present woman with epilepsy who was used combined low dose oral contraceptive pills containing 20 microg of ethinyl estradiol which in interaction with carbamazepine resulted with ectopic tubar pregnancy.

  19. Ectopic expression of SUPERMAN suppresses development of petals and stamens.

    Science.gov (United States)

    Yun, Jae-Young; Weigel, Detlef; Lee, Ilha

    2002-01-01

    The floral regulatory gene SUPERMAN (SUP) encodes a C2H2 type zinc finger protein that is required for maintaining boundaries between floral organs in Arabidopsis. It has been proposed that the main function of SUP is to balance cell proliferation in the third and fourth whorl of developing flowers, thereby maintaining the boundaries between the two whorls. To gain further insight into the function of SUP, we have ectopically expressed SUP using the promoter of APETALA1 (AP1), a gene that is initially expressed throughout floral meristems and later becomes restricted to the first and second whorls. Flowers of AP1::SUP plants have fewer floral organs, consistent with an effect of SUP on cell proliferation. In addition, the AP1::SUP transgene caused the conversion of petals to sepals and suppressed the development of stamens. The expression of the B function homeotic gene APETALA3 (AP3) and its regulator UNUSUAL FLORAL ORGANS (UFO) were delayed and reduced in AP1::SUP flowers. However, SUP does not act merely through UFO, as constitutive expression of UFO did not rescue the defects in petal and stamen development in AP1::SUP flowers. Together, these results suggest that SUP has both indirect and direct effects on the expression of B function homeotic genes.

    Full Text Available Adrenal incidentalomas are clinical dilemmas for the clinicians. The work up, to differentiate between malignant and benign lesions, and hyperfunctioning and nonfunctioning lesions is mandatory before the consideration of surgical resection. Ectopic thyroid tissue located in the adrenal gland (ETTAG is a very rare condition. We report a case of ETTAG presenting with adrenal incidentaloma. A 57-year-old woman was admitted with incidental right adrenal mass. Hormone evaluation showed no hormonal activity. Magnetic resonance imaging revealed a 20x17 mm lobulated solid mass, which contained millimetric hypointense nodular areas consistent with calcifications. Loss of signal intensity on out-of-phase could not be evaluated because of the calcifications. Right adrenalectomy was performed to establish the histopathological diagnosis and to rule out malignancy. Histopathological diagnosis revealed ETTAG. Her medical history was positive for multinodular goiter and bilateral subtotal thyroidectomy 32 years ago. Thyroid ultrasonography showed residual thyroid tissue in both the right and left lobes, and colloid thyroid nodules. Fine needle aspiration biopsy from the nodules revealed benign nodules. The patient has been followed up for six years, and no change in thyroid nodule sizes and no evidence of metastatic foci have been detected. ETTAG would be considered in the differential diagnosis of adrenal mass showing no hormonal activity, especially when magnetic resonance images are not consistent with adrenal adenoma. Long follow-up duration of this case suggests that it was a benign condition.

    OBJECTIVE To assess national trends in ectopic pregnancy incidence among assisted reproductive technology users and identify risk factors associated with ectopic pregnancy. METHODS We identified 553,577 pregnancies reported to the National ART Surveillance System between 2001 and 2011. Of those, 9,480 were ectopic, of which 485 were heterotopic. As a result of small numbers, ectopic and heterotopic pregnancies were combined for analysis. We assessed temporal trends in annual ectopic pregnancy rates using Poisson regression. We used log-binomial regression models with generalized estimating equations for correlated outcomes within clinics to calculate unadjusted and adjusted risk ratios for the association between ectopic pregnancy and selected patient characteristics and treatment factors. RESULTS The rate of ectopic pregnancy declined from 2.0% (n5735, 95% confidence interval [CI] 1.9–2.2) in 2001 to 1.6% (n=968, 95% CI 1.5–1.7) in 2011 (P for trend ,.001). The ectopic pregnancy rate ranged from 2.0% (n=7,469, 95% CI 1.9–2.0) for fresh, nondonor cycles to 1.0% (n=641, 95% CI 0.9–1.1) for fresh, donor cycles. Among fresh, nondonor cycles, the rate of ectopic pregnancy was 1.6% (95% CI 1.4–1.7) when one embryo was transferred compared with 1.7% (95% CI 1.7–1.8), 2.2% (95% CI 2.1–2.3), and 2.5% (95% CI 2.4–2.6) when two, three, or four or more embryos were transferred, respectively (adjusted risk ratios 1.11, 95% CI 0.94–0.30; 1.33, 95% CI 1.12–1.56; and 1.49, 95% CI 1.25–1.78). CONCLUSION Ectopic pregnancy incidence after assisted reproductive technology has decreased over time, but factors such as multiple embryo transfer increase the risk of ectopic pregnancy.

    Pseudoxanthoma elasticum (PXE) is a multisystem ectopic mineralization disorder caused by mutations in the ABCC6 gene. Warfarin, a commonly used anticoagulant, is associated with increased mineralization of the arterial blood vessels and cardiac valves. We hypothesized that warfarin may accelerate ectopic tissue mineralization in PXE, with clinical consequences. To test this hypothesis, we developed a model in which Abcc6−/− mice, which recapitulate features of PXE, were fed a diet supplement...

    Wenshen Xiaozheng Tang (WXT), a traditional Chinese medicine prescription, exerted a good therapeutic effect on endometriosis. However, the underlying mechanism is unclear. In the present study, we sought to evaluate the effect of WXT on the proliferation and migration of ectopic endometriotic stromal cells and explore the potential molecular mechanism. Primary stromal cells derived from ectopic endometriotic lesions of patients with endometriosis were isolated and cultured. The inhibition effect of WXT on cell proliferation was determined by MTT. Apoptosis of ectopic endometriotic cells treated with WXT was analyzed with Annexin V-FITC/7-AAD staining. The activation of caspases was detected by western blot analysis. The influence of WXT on migration of ectopic endometriotic cells was measured by scratch wound healing assay and Transwell assay. The DNA binding activity of NF-κB and the expression of nuclear p65 protein were determined by electrophoretic mobility shift assay and western blot analysis, respectively. The impact of WXT on the expression of NF-κB regulated gene products involved in apoptosis and migration was determined by western blot analysis. WXT inhibited the proliferation of ectopic endometriotic cells in a time- and dose-dependent manner. In addition, WXT treatment resulted in significant induction of apoptosis through the activation of caspases and inhibition of migration in ectopic endometriotic cells. WXT notably suppressed constitutive NF-κB-DNA-binding activity as well as TNF-α induced nuclear translocation of NF-κB p65 subunit in ectopic endometriotic cells. Moreover, WXT diminished the expression of NF-κB regulated gene products involved in apoptosis and migration, including c-IAP1, c-IAP2, XIAP, survivin, Mcl-1, COX-2 and MMP-9. Our results indicate that WXT induces apoptosis and inhibits migration of ectopic endometriotic stromal cells. Copyright © 2016. Published by Elsevier Ireland Ltd.

    Ectopic pregnancy is a frequent early complication of pregnancy associated with significant rates of morbidly and mortality. The positive diagnosis of this condition is established through transvaginal ultrasound scanning. The timing of diagnosis depends on the operator expertise in identifying the signs of ectopic pregnancy, which varies dramatically among medical staff with heterogeneous training. Developing decision support systems in this context is expected to improve the identification of these signs and subsequently improve the quality of care. In this article, we present a new knowledge base for ectopic pregnancy, and we demonstrate its use on the annotation of clinical images. The knowledge base is supported by an application ontology, which provides the taxonomy, the vocabulary and definitions for 24 types and 81 signs of ectopic pregnancy, 484 anatomical structures and 32 technical elements for image acquisition. The knowledge base provides a sign-centric model of the domain, with the relations of signs to ectopic pregnancy types, anatomical structures and the technical elements. The evaluation of the ontology and knowledge base demonstrated a positive feedback from a panel of 17 medical users. Leveraging these semantic resources, we developed an application for the annotation of ultrasound images. Using this application, 6 operators achieved a precision of 0.83 for the identification of signs in 208 ultrasound images corresponding to 35 clinical cases of ectopic pregnancy. We developed a new ectopic pregnancy knowledge base for the annotation of ultrasound images. The use of this knowledge base for the annotation of ultrasound images of ectopic pregnancy showed promising results from the perspective of clinical decision support system development. Other gynecological disorders and fetal anomalies may benefit from our approach.

  19. Ectopic KNOX Expression Affects Plant Development by Altering Tissue Cell Polarity and Identity.

    Science.gov (United States)

    Richardson, Annis Elizabeth; Rebocho, Alexandra B; Coen, Enrico S

    2016-08-23

    Plant development involves two polarity types: tissue cell (asymmetries within cells are coordinated across tissues) and regional (identities vary spatially across tissues) polarity. Both appear altered in the barley (Hordeum vulgare) Hooded mutant, in which ectopic expression of the KNOTTED1-like Homeobox (KNOX) gene, BKn3, causes inverted polarity of differentiated hairs and ectopic flowers, in addition to wing-shaped outgrowths. These lemma-specific effects allow the spatiotemporal analysis of events following ectopic BKn3 expression, determining the relationship between KNOXs, polarity, and shape. We show that tissue cell polarity, based on localization of the auxin transporter SISTER OF PINFORMED1 (SoPIN1), dynamically reorients as ectopic BKn3 expression increases. Concurrently, ectopic expression of the auxin importer LIKE AUX1 and boundary gene NO APICAL MERISTEM is activated. The polarity of hairs reflects SoPIN1 patterns, suggesting that tissue cell polarity underpins oriented cell differentiation. Wing cell files reveal an anisotropic growth pattern, and computational modeling shows how polarity guiding growth can account for this pattern and wing emergence. The inverted ectopic flower orientation does not correlate with SoPIN1, suggesting that this form of regional polarity is not controlled by tissue cell polarity. Overall, the results suggest that KNOXs trigger different morphogenetic effects through interplay between tissue cell polarity, identity, and growth.

    Plant development involves two polarity types: tissue cell (asymmetries within cells are coordinated across tissues) and regional (identities vary spatially across tissues) polarity. Both appear altered in the barley (Hordeum vulgare) Hooded mutant, in which ectopic expression of the KNOTTED1-like Homeobox (KNOX) gene, BKn3, causes inverted polarity of differentiated hairs and ectopic flowers, in addition to wing-shaped outgrowths. These lemma-specific effects allow the spatiotemporal analysis of events following ectopic BKn3 expression, determining the relationship between KNOXs, polarity, and shape. We show that tissue cell polarity, based on localization of the auxin transporter SISTER OF PINFORMED1 (SoPIN1), dynamically reorients as ectopic BKn3 expression increases. Concurrently, ectopic expression of the auxin importer LIKE AUX1 and boundary gene NO APICAL MERISTEM is activated. The polarity of hairs reflects SoPIN1 patterns, suggesting that tissue cell polarity underpins oriented cell differentiation. Wing cell files reveal an anisotropic growth pattern, and computational modeling shows how polarity guiding growth can account for this pattern and wing emergence. The inverted ectopic flower orientation does not correlate with SoPIN1, suggesting that this form of regional polarity is not controlled by tissue cell polarity. Overall, the results suggest that KNOXs trigger different morphogenetic effects through interplay between tissue cell polarity, identity, and growth. PMID:27553356

    When a dental implant migrates to the maxillary sinus it should be extracted immediately as it may cause sinusitis or further migrate to one of the other paranasal sinuses. Although usually detected due to symptoms such as nasal obstruction, nasal discharge, and nasal bleeding, an ectopic tooth in the maxillary sinus can sometimes be revealed incidentally on radiographic examination. Here, we report a case of simultaneous extraction of a dental implant that had migrated to the maxillary sinus and removal of an ectopic tooth that had arisen in the same location. The patient was a 73-year-old man who had received the implant to replace the first left maxillary molar at a local dental office. The implant had subsequently migrated to the left maxillary sinus and the patient was referred to us for its removal. On locating the implant on a CT scan at our hospital, an ectopic tooth was also observed at the base of the maxillary sinus. With patient consent, the decision was made to remove the ectopic tooth and extract the implant simultaneously. Excision of the lateral wall of the maxillary sinus allowed easy extraction of the implant. The ectopic tooth was removed by slightly expanding a fenestration in the sinus wall. Ectopic teeth in the maxillary sinus are sometimes put on follow-up if asymptomatic. Removal should be considered, however, if there is a risk of it becoming infected due to implantation-induced inflammation.

    Analysis of heart rate variability (HRV) has been used in studies of autonomic function and risk assessment in different patient groups such as in patients with diabetes mellitus, after myocardial infarction (MI) and other cardiovascular disease. Ectopic beats can, however, interfere with HRV analysis and give erroneous results. We have therefore studied the impact of ectopic beats on HRV analysis and the ability of a filter algorithm to correct this. Power spectral analysis of synthetic data with an increasing proportion of ectopic beats and 24-h Holter recordings from 98 healthy subjects and 93 post MI patients was done with and without digital filtering and interpolation of errors in the data stream. The analysis of HRV was seriously hampered by less than 1% of ectopic beats. A filter algorithm based on detection and linear interpolation of ectopic beats and other noise in the data stream corrected effectively for this in the synthetic data employed. In the healthy subjects and the post MI patients, filtering markedly reduced the extra variability related to non-normal beats. The software could automatically analyse over one hundred 24-h files in one batch. HRV analysis should include filtering for ectopic beats even with a small number of such beats. It is possible to make a fast analysis automatically even in huge clinical series, which makes it possible to use the method both clinically and in epidemiological studies.

    Abscisic acid (ABA) regulates seed maturation, germination and various stress responses in plants. The roles of ABA in cellular growth and morphogenesis, however, remain to be explored. Here, we report that ABA induces the ectopic outgrowth of epidermal cells in Arabidopsis thaliana. Seedlings of A. thaliana germinated and grown in the presence of ABA developed ectopic protrusions in the epidermal cells of hypocotyls, petioles and cotyledons. One protrusion was formed in the middle of each epidermal cell. In the hypocotyl epidermis, two types of cell files are arranged alternately into non-stoma cell files and stoma cell files, ectopic protrusions being restricted to the non-stoma cell files. This suggests the presence of a difference in the degree of sensitivity to ABA or in the capacity of cells to form protrusions between the two cell files. The ectopic outgrowth was suppressed in ABA insensitive mutants, whereas it was enhanced in ABA hypersensitive mutants. Interestingly, ABA-induced ectopic outgrowth was also suppressed in mutants in which microtubule organization was compromised. Furthermore, cortical microtubules were disorganized and depolymerized by the ABA treatment. These results suggest that ABA signaling induces ectopic outgrowth in epidermal cells through microtubule reorganization. PMID:26068445

    Multiple tumor-like ectopic calcifications is a rare syndrome characterized by subcutaneous mass deposits of calcium phosphate in periarticular tissues. Although several cases of the surgical treatment of tumoral calcinosis have been reported, the present case is unique in that multiple ectopic calcifications in subcutaneous tissues were found in a hemodialysis patient who had been operated on a total of five times within a period of 1.5 years. A hemodialysis 60-year-old male presented with multiple tumor-like ectopic calcifications bilateral in the shoulders, right buttock and right thigh. He had been operated on a total of five times within a period of 1.5 years; the operations included a subtotal parathyroidectomy with parathyroid autotransplantation in the right forearm. Complete excisions of the ectopic calcifications were performed in the left shoulder, right buttock and right thigh, without signs of recurrence in the same sites at follow-up. Incomplete excision of the ectopic calcification in the right shoulder resulted in recurrence in the same site, and the patient was operated on two more times 1.5 years following the initial surgery. Subtotal parathyroidectomy with parathyroid autotransplantation decreased serum levels of PTH, but the levels of serum calcium and phosphorus remained unchanged post-surgery, which appeared not to inhibit the recurrence of ectopic calcification in patients with CRF. If conservative therapy failed, then early and complete surgical excision may be a good therapeutic option. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    Ectopic pancreas is most commonly found in the jejunum and stomach. Most patients remain asymptomatic, and the diagnosis is usually made at autopsy or incidentally. We report here 2 cases of intestinal occlusion, secondary to an ectopic pancreatic tissue. Both cases were managed successfully by laparoscopy and laparotomy with subsequent segmental intestinal resection. Case 1 - An elderly patient presented to the ER because of intestinal occlusion. Paraclinical investigations were consistent with occlusion, with ileal suffering signs on CT-scan. After laparotomy and segmental intestinal resection were done, histopathalogy showed evidence of ectopic pancreas obstructing the intestinal lumen. Case 2 - A young man presented to the ER with acute onset of epigastric pain. signs of peritoneal irritation. Ct-scan showed evidence of small bowel intussusception. Exploratory laparoscopy was done, and confirmed the diagnosis. The intussusceptum was at the level of the proximal jejunum. The suffering intestinal part was exteriorized and then resected. Histopathology was consistent with an ectopic pancreas. Symptomatic ectopic pancreas is extremely rare. Symptoms may include, bleeding, intestinal occlusion and intussusception. Few similar cases have been reported in the literature, and the current ones are to be added. As mentioned above, ectopic pancreatic tissue rarely causes symptoms. We presented 2 cases that presented 2 possible complications secondary to this pathology. Both cases were managed successfully. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    Objective: Bilateral tubal ectopic pregnancies are rare; the reported incidence is only 1 in 200 000 pregnancies. Detecting bilateral tubal ectopic pregnancy is urgent because of the associated morbidity and mortality. The appropriate fertility-preserving surgery must also be considered, as preservation of both tubes is presumed to offer better fertility prospects. Case Report: A 39-year-old gravida 2, para 1 presented with vaginal bleeding at 8 + 4 weeks of gestation. An approximately 18 mm adnexal mass in the right fallopian tube was detected on ultrasound. Laparoscopy was performed because ectopic pregnancy was suspected. This suspicion was confirmed during laparoscopy; the right fallopian tube was found to contain a mass measuring 20 mm in the isthmic part. Ultrasound of the left fallopian tube also showed a mass in the ampullary region (diameter: 10 mm), also suspicious for ectopic pregnancy. Bilateral salpingotomy was performed laparoscopically. Pathological examination confirmed the diagnosis. Conclusions for Practice: Although ectopic tubal pregnancy is seen more often after assisted reproductive techniques, bilateral spontaneous ectopic pregnancies must also be considered in other cases. Laparoscopic surgery is effective to confirm the diagnosis and treat heterotopic pregnancies. Further studies will be needed to confirm whether unilateral or bilateral conservative fertility-preserving surgery is more appropriate.

    To investigate the feasibility and safety of single port laparoscopic surgery (SP-LS) for ectopic pregnancy, irrespective of type of ectopic pregnancy and hemodynamic stability. A prospective case-control study of 106 women who underwent SP-LS or conventional LS for a suspected ectopic pregnancy was performed at a university teaching hospital from January 2009 to March 2012. Twenty-six women underwent SP-LS (SP-LS group) and 80 women underwent conventional LS (conventional LS group). There were no statistical differences between the groups in terms of demographic characteristics, operating time, hemoglobin change, return of bowel activity, hospital stay or complication rate. There were no cases of additional trocar use or conversion to laparotomy. Of five women with heterotopic pregnancy, one underwent SP-LS, and three underwent conventional LS for tubal pregnancy, which all resulted in vaginal delivery without obstetric complication; one woman received SP-LS for cornual pregnancy and had an ongoing pregnancy. SP-LS for ectopic pregnancy is feasible and safe regardless of the type of ectopic pregnancy and hemodynamic stability. However, further work is needed to confirm this conclusion and to demonstrate any advantage of SP-LS for ectopic pregnancy. © 2014 The Authors.

    Cushing's syndrome is caused by excessive adrenocorticotropic hormone (ACTH) secretion derived from pituitary corticotroph tumors (Cushing disease) or from non-pituitary tumors (ectopic Cushing's syndrome). Hypercortisolemic features of ectopic Cushing's syndrome are severe, and no definitive treatment for paraneoplastic ACTH excess is available. We aimed to identify subcellular therapeutic targets by elucidating transcriptional regulation of the human ACTH precursor POMC (proopiomelanocortin) and ACTH production in non-pituitary tumor cells and in cell lines derived from patients with ectopic Cushing's syndrome. We show that ectopic hPOMC transcription proceeds independently of pituitary-specific Tpit/Pitx1 and demonstrate a novel E2F1-mediated transcriptional mechanism regulating hPOMC We identify an E2F1 cluster binding to the proximal hPOMC promoter region (-42 to +68), with DNA-binding activity determined by the phosphorylation at Ser-337. hPOMC mRNA expression in cancer cells was upregulated (up to 40-fold) by the co-expression of E2F1 and its heterodimer partner DP1. Direct and indirect inhibitors of E2F1 activity suppressed hPOMC gene expression and ACTH by modifying E2F1 DNA-binding activity in ectopic Cushing's cell lines and primary tumor cells, and also suppressed paraneoplastic ACTH and cortisol levels in xenografted mice. E2F1-mediated hPOMC transcription is a potential target for suppressing ACTH production in ectopic Cushing's syndrome. © 2016 Society for Endocrinology.

    Ectopic pregnancy is an obstetrical disease that is potentially associated with maternal death in the first trimester. It is one of the well-known complications following in vitro fertilization (IVF) with embryo transfer (ET). The incidence of ectopic pregnancy is estimated to be 2.1-8.6% of clinical pregnancy after IVF-ET, which is higher than natural conceptions (incidence rate 2%). This study aimed to re-evaluate the ectopic pregnancy rate in patients undergoing IVF-ET and to investigate the effects of embryo stage and frozen-thawed blastocyst transfer and ET during full bladder distention on ectopic pregnancy rate. This retrospective study reviewed women who achieved a clinical pregnancy after IVF-ET at the Department of Obstetrics and Gynecology, Kaohsiung Chang Gung Memorial Hospital between 1999 and 2013. We compared ectopic pregnancy rate following Day 3 ET with Day 5 ET, and after fresh ET with thawed ET. Besides, multivariate analysis was used to clarify the factors affecting ectopic pregnancy after IVF-ET. Of the total 1213 clinical pregnancies after fresh ET, 18 (1.5%) were verified as ectopic, which is similar to the rate following natural conception. The ectopic pregnancy rates were similar for Day 3 (1.2%) and Day 5 (1.7%) ETs. The incidence of ectopic pregnancy in thawed ET cycles (0.6%) was not significantly reduced than fresh ET cycles (1.5%). Tubal ET (TET) and ET under full bladder distention had a significant effect on ectopic pregnancy. Thawed ET was not associated with a lower incidence of ectopic pregnancy than fresh ET, and embryo stage did not affect the rate of ectopic pregnancy. In addition, TET and ET under conditions of full bladder distention may increase the ectopic pregnancy rate. Copyright © 2015. Published by Elsevier B.V.

    Full Text Available Background: Although the risk factors of ectopic pregnancy have been determined in previous studies, the main risk factors of ectopic pregnancy are different in various countries due to different cultural and social characteristics. Determination of main risk factors of ectopic pregnancy leads to a rapid diagnosis and an improvement in strategies for its prevention. The purpose of this study was to determine the main risk factors of ectopic pregnancy in a sample of Iranian women. Materials and Methods: We designed a case-control study to include 150 cases and 300 controls and to compare them by the following factors: socio-demographic characteristics, contraceptive methods, prior tubal surgery, tubal pathology, prior ectopic pregnancy, prior caesarean section, prior abortion, prior infertility, and prior abdominal/pelvic surgery. Results: The case and control groups were significantly similar in term of education and parity. There was an association between ectopic pregnancy and age which was disappeared after controlling for the main risk factors (adjusted OR=2.45, 95% CI: 0.86-6.97. There was no statistically significant relation between ectopic pregnancy and prior tubal surgery, tubal pathology, prior abortion, prior infertility, assisted reproductive technology, and oral contraceptive method (p>0.05. However, there was a significant association between prior ectopic pregnancy, prior tubal ligation, use of intrauterine device, and prior abdominal/pelvic surgery with ectopic pregnancy (p<0.05. The risk of ectopic pregnancy increased with the use of intrauterine device and tubal ligation, whereas decreased with use of oral contraception. Conclusion: This study identified prior ectopic pregnancy, prior tubal ligation, use of intrauterine device, and prior pelvic/abdominal surgery as the main risk factors for ectopic pregnancy in a sample of Iranian women. Our findings can be useful for early diagnosis of ectopic pregnancy and for improvement in

    STUDY QUESTION Does the risk of adverse outcomes at the time of ectopic pregnancy vary by race/ethnicity among women receiving Medicaid, the public health insurance program for low-income people in the USA? SUMMARY ANSWER Among Medicaid beneficiaries with ectopic pregnancy, 11% experienced at least one complication, and women from all racial/ethnic minority groups were significantly more likely than whites to experience complications. WHAT IS KNOWN ALREADY In this population of Medicaid recipients, African American women are significantly more likely than whites to experience ectopic pregnancy, but the risk of adverse outcomes has not previously been assessed. STUDY DESIGN, SIZE, AND DURATION We conducted a cross-sectional observational study of all women (n = 19 135 106) ages 15–44 enrolled in Medicaid for any amount of time during 2004–2008 who lived in one of the following 14 US states: Arizona; California; Colorado; Florida; Illinois; Indiana; Iowa; Louisiana; Massachusetts; Michigan; Minnesota; Mississippi; New York; and Texas. PARTICIPANTS/MATERIALS, SETTINGS, METHODS We analyzed Medicaid claims records for inpatient and outpatient encounters and identified ectopic pregnancies with a principal diagnosis code for ectopic pregnancy from 2004–2008. We calculated the ectopic pregnancy complication rate as the number of ectopic pregnancies with at least one complication (blood transfusion, hysterectomy, any sterilization, or length-of-stay (LOS) > 2 days) divided by the total number of ectopic pregnancies. We used Poisson regression to assess the risk of ectopic pregnancy complication by race/ethnicity. Secondary outcomes were each individual complication, and ectopic pregnancy-related death. We calculated the ectopic pregnancy mortality ratio as the number of deaths divided by live births. MAIN RESULTS AND THE ROLE OF CHANCE Ectopic pregnancy-associated complications occurred in 11% of cases. Controlling for age and state, the risk of any complication was

    What type of transferred embryo is associated with a lower rate of ectopic pregnancy? The lowest risk of ectopic pregnancy was associated with the transfer of blastocyst, frozen and single embryo compared with cleavage stage, fresh and multiple embryos. Ectopic pregnancy is a recognized complication following assisted reproductive technology (ART) treatment. It has been estimated that the rate of ectopic pregnancy is doubled in pregnancies following ART treatment compared with spontaneous pregnancies. However, it was not clear whether the excess rate of ectopic pregnancy following ART treatment is related to the underlying demographic factors of women undergoing ART treatment, the number of embryos transferred or the developmental stage of the embryo. A population-based cohort study of pregnancies following autologous treatment cycles between January 2009 and December 2011 were obtained from the Australian and New Zealand Assisted Reproduction Technology Database (ANZARD). The ANZARD collects ART treatment information and clinical outcomes annually from all fertility centres in Australia and New Zealand. Between 2009 and 2011, a total of 44 102 pregnancies were included in the analysis. The rate of ectopic pregnancy was compared by demographic and ART treatment factors. Generalized linear regression of Poisson distribution was used to estimate the likelihood of ectopic pregnancy. Odds ratios, adjusted odds ratios (AOR) and 95% confidence intervals (CI) were calculated. The overall rate of ectopic pregnancy was 1.4% for women following ART treatment in Australia and New Zealand. Pregnancies following single embryo transfers had 1.2% ectopic pregnancies, significantly lower than double embryo transfers (1.8%) (P ectopic pregnancy rate was 1.9% for pregnancies from transfers of fresh cleavage embryo, followed by transfers of frozen cleavage embryo (1.7%), transfers of fresh blastocyst (1.3%), and transfers of frozen blastocyst (0.8%). Compared with fresh blastocyst

    Full Text Available Our objective was to determine the expression of the elements of the Lin28/Let-7 system, and related microRNAs (miRNAs, in early stages of human placentation and ectopic pregnancy, as a means to assess the potential role of this molecular hub in the pathogenesis of ectopic gestation. Seventeen patients suffering from tubal ectopic pregnancy (cases and forty-three women with normal on-going gestation that desired voluntary termination of pregnancy (VTOP; controls were recruited for the study. Embryonic tissues were subjected to RNA extraction and quantitative PCR analyses for LIN28B, Let-7a, miR-132, miR-145 and mir-323-3p were performed. Our results demonstrate that the expression of LIN28B mRNA was barely detectable in embryonic tissue from early stages of gestation and sharply increased thereafter to plateau between gestational weeks 7-9. In contrast, expression levels of Let-7, mir-132 and mir-145 were high in embryonic tissue from early gestations (≤ 6-weeks and abruptly declined thereafter, especially for Let-7. Opposite trends were detected for mir-323-3p. Embryonic expression of LIN28B mRNA was higher in early stages (≤ 6-weeks of ectopic pregnancy than in normal gestation. In contrast, Let-7a expression was significantly lower in early ectopic pregnancies, while miR-132 and miR-145 levels were not altered. Expression of mir-323-3p was also suppressed in ectopic embryonic tissue. We are the first to document reciprocal changes in the expression profiles of the gene encoding the RNA-binding protein, LIN28B, and the related miRNAs, Let-7a, mir-132 and mir-145, in early stages of human placentation. This finding suggests the potential involvement of LIN28B/Let-7 (deregulated pathways in the pathophysiology of ectopic pregnancy in humans.

    Ectopic cilia are extremely rare congenital anomalies in which eyelash follicles appear in an abnormal place on the eyelid, most typically on the lateral quadrant of the anterior surface of the upper eyelid. In the majority of cases, simple surgical excision of ectopic cilia is indicated because of its cosmetic aspect. There is usually no associated medical co-morbidity with this anomaly. The authors report an unusual case of ectopic cilia associated with an orbital dermoid cyst and sinus tract. A 3-year-old boy was initially diagnosed with ectopic cilia on the left upper eyelid. There was no history of inflammation or swelling of the eyelid. An ophthalmological examination revealed only 1 mm of ptosis; no proptosis, inferior displacement, or palpable orbital mass was present. During surgical excision of the ectopic cilia, a thin sinus tract was identified, leading posteriorly to the orbit. Magnetic resonance imaging performed after the excision showed a supraorbital extraconal mass just below the roof of the left orbit. A supraorbital 2-piece craniotomy was performed with total extirpation of the dermoid cyst. The cyst was removed en bloc without damage to the extraocular muscles, but the sinus tract could no longer be identified. Follow-up MRI was performed 6 months after surgery and showed no evidence of recurrence. A follow-up ophthalmological examination showed no signs of inferior displacement or proptosis. To the best of the authors' knowledge, this case is the first reported instance of ectopic cilia associated with a dermoid cyst and sinus tract in which no typical clinical signs and symptoms of possible orbital pathology were present. This case highlights the value of radiological examination in all cases of ectopic cilia prior to surgical excision.

    Localization of the source of cardiac ectopic activity has direct clinical benefits for determining the location of the corresponding ectopic focus. In this study, a recently developed current-density (CD)-based localization approach was experimentally evaluated in noninvasively localizing the origin of the cardiac ectopic activity from body-surface potential maps (BSPMs) in a well-controlled experimental setting. The cardiac ectopic activities were induced in four well-controlled intact pigs by single-site pacing at various sites within the left ventricle (LV). In each pacing study, the origin of the induced ectopic activity was localized by reconstructing the CD distribution on the endocardial surface of the LV from the measured BSPMs and compared with the estimated single moving dipole (SMD) solution and precise pacing site (PS). Over the 60 analyzed beats corresponding to ten pacing sites (six for each), the mean and standard deviation of the distance between the locations of maximum CD value and the corresponding PSs were 16.9 mm and 4.6 mm, respectively. In comparison, the averaged distance between the SMD locations and the corresponding PSs was slightly larger (18.4 ± 3.4 mm). The obtained CD distribution of activated sources extending from the stimulus site also showed high consistency with the endocardial potential maps estimated by a minimally invasive endocardial mapping system. The present experimental results suggest that the CD method is able to locate the approximate site of the origin of a cardiac ectopic activity, and that the distribution of the CD can portray the propagation of early activation of an ectopic beat.

    Ectopic (accessory) adrenocortical tissue, also known as adrenal rests, is a developmental abnormality of the adrenal gland. The most common ectopic site is in close proximity to the adrenal glands and along the path of descent or migration of the gonads because of the close spatial relationship between the adrenocortical primordium and gonadal blastema during embryogenesis. Ectopic rests may undergo marked hyperplasia, and occasionally induce ectopic adrenocortical adenomas or carcinomas. A 27-year-old Chinese female patient who presented with amenorrhea of 3 months duration underwent computed tomography urography after ultrasound revealed a solitary mass in the left renal hilum. Histologically, the prominent eosinophilic tumor cells formed an alveolar- or acinar-like configuration. The immunohistochemical profile (alpha-inhibin+, Melan-A+, synaptophysin+) indicated the adrenocortical origin of the tumor, diagnosed as ectopic adrenocortical adenoma. The patient was alive with no tumor recurrence or metastasis at the 3-month follow-up examination. The unusual histological appearance of ectopic adrenocortical adenoma may result in its misdiagnosis as oncocytoma or clear cell renal cell carcinoma, especially if the specimen is limited. This case provides a reminder to pathologists to be aware of atypical cases of this benign tumor. Although uncommon, an ectopic adrenal lesion should be included in the differential diagnosis of tumors involving the renal hilum. A misdiagnosis of this benign condition as a malignant renal tumor may have severe consequences for the patient, including unnecessary radical nephrectomy. Preoperative biopsy and appropriate immunohistochemical staining will assist in determining the origin and nature of the tumor and in avoiding intraoperative uncertainty.

    SpaD is the predicted backbone-pilin subunit of the SpaFED pilus, whose loci are encoded by the fimbrial spaFED operon in Lactobacillus rhamnosus GG, a Gram-positive gut-adapted commensal strain with perceived probiotic benefits. In this study, soluble recombinant SpaD protein was overproduced in Escherichia coli and then purified by Ni2+-chelating affinity and gel-filtration chromatography. After limited proteolysis with α-chymotrypsin, good-quality crystals of SpaD were obtained which diffracted beyond 2.0 Å resolution. These crystals belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a=50.11, b=83.27, c=149.65 Å. For phasing, sodium iodide-derivatized crystals were prepared using the halide quick-soaking method and diffraction data were collected in-house to a resolution of 2.2 Å. An interpretable electron-density map was successfully obtained using single-wavelength anomalous diffraction (SAD).

    The enteric bacterium Proteus mirabilis is associated with a significant number of catheter-associated urinary tract infections (UTIs). Strict regulation of the antagonistic processes of adhesion and motility, mediated by fimbriae and flagella, respectively, is essential for disease progression. Previously, the transcriptional regulator MrpJ, which is encoded by the mrp fimbrial operon, has been shown to repress both swimming and swarming motility. Here we show that MrpJ affects an array of cellular processes beyond adherence and motility. Microarray analysis found that expression of mrpJ mimicking levels observed during UTIs leads to differential expression of 217 genes related to, among other functions, bacterial virulence, type VI secretion, and metabolism. We probed the molecular mechanism of transcriptional regulation by MrpJ using transcriptional reporters and chromatin immunoprecipitation (ChIP). Binding of MrpJ to two virulence-associated target gene promoters, the promoters of the flagellar master regulator flhDC and mrp itself, appears to be affected by the condensation state of the native chromosome, although both targets share a direct MrpJ binding site proximal to the transcriptional start. Furthermore, an mrpJ deletion mutant colonized the bladders of mice at significantly lower levels in a transurethral model of infection. Additionally, we observed that mrpJ is widely conserved in a collection of recent clinical isolates. Altogether, these findings support a role of MrpJ as a global regulator of P. mirabilis virulence.

    Retroperitoneal abdominal pregnancy is exceptionally rare. An unusual retroperitoneal pregnancy has a high risk of severe bleeding. Abdominal ultrasonography and whole abdominal computerized tomography scanning should be performed for the early diagnosis of ectopic pregnancy. A case of retroperitoneal ectopic pregnancy located very close to large retroperitoneal blood vessels and treated with resection is presented. Many unusual features of retroperitoneal ectopic pregnancy were highlighted as providing further evidence in support of the main proposed embryo migration mechanism via lymphatic vessels.

    Background Although the risk factors of ectopic pregnancy have been determined in previous studies, the main risk factors of ectopic pregnancy are different in various countries due to different cultural and social characteristics. Determination of main risk factors of ectopic pregnancy leads to a rapid diagnosis and an improvement in strategies for its prevention. The purpose of this study was to determine the main risk factors of ectopic pregnancy in a sample of Iranian women. Materials and Methods We designed a case-control study to include 150 cases and 300 controls and to compare them by the following factors: socio-demographic characteristics, contraceptive methods, prior tubal surgery, tubal pathology, prior ectopic pregnancy, prior caesarean section, prior abortion, prior infertility, and prior abdominal/pelvic surgery. Results The case and control groups were significantly similar in term of education and parity. There was an association between ectopic pregnancy and age which was disappeared after controlling for the main risk factors (adjusted OR=2.45, 95% CI: 0.86-6.97). There was no statistically significant relation between ectopic pregnancy and prior tubal surgery, tubal pathology, prior abortion, prior infertility, assisted reproductive technology, and oral contraceptive method (p>0.05). However, there was a significant association between prior ectopic pregnancy, prior tubal ligation, use of intrauterine device, and prior abdominal/pelvic surgery with ectopic pregnancy (pectopic pregnancy increased with the use of intrauterine device and tubal ligation, whereas decreased with use of oral contraception. Conclusion This study identified prior ectopic pregnancy, prior tubal ligation, use of intrauterine device, and prior pelvic/abdominal surgery as the main risk factors for ectopic pregnancy in a sample of Iranian women. Our findings can be useful for early diagnosis of ectopic pregnancy and for improvement in strategies of its prevention through

    Ectopic pregnancy is the leading cause of maternal morbidity and mortality during the first trimester and the incidence increases dramatically with assisted-reproductive technology (ART), occurring in approximately 1.5-2.1 % of patients undergoing in-vitro fertilization (IVF). Abdominal ectopic pregnancy is a rare yet clinically significant form of ectopic pregnancy due to potentially high maternal morbidity. While risk factors for ectopic pregnancy after IVF have been studied, very little is known about risk factors specific for abdominal ectopic pregnancy. We present a case of a 30 year-old woman who had an abdominal ectopic pregnancy following IVF and elective single embryo transfer, which was diagnosed and managed by laparoscopy. We performed a systematic literature search to identify case reports of abdominal or heterotopic abdominal ectopic pregnancies after IVF. A total of 28 cases were identified. Patients' ages ranged from 23 to 38 (Mean 33.2, S.D. = 3.2). Infertility causes included tubal factor (46 %), endometriosis (14 %), male factor (14 %), pelvic adhesive disease (7 %), structural/DES exposure (7 %), and unexplained infertility (14 %). A history of ectopic pregnancy was identified in 39 % of cases. A history of tubal surgery was identified in 50 % of cases, 32 % cases having had bilateral salpingectomy. Transfer of two embryos or more (79 %) and fresh embryo transfer (71 %) were reported in the majority of cases. Heterotopic abdominal pregnancy occurred in 46 % of cases while 54 % were abdominal ectopic pregnancies. Our systematic review has revealed several trends in reported cases of abdominal ectopic pregnancy after IVF including tubal factor infertility, history of tubal ectopic and tubal surgery, higher number of embryos transferred, and fresh embryo transfers. These are consistent with known risk factors for ectopic pregnancy following IVF. Further research focusing on more homogenous population may help in better characterizing

  7. Effects of aerobic exercise on ectopic lipids in patients with growth hormone deficiency before and after growth hormone replacement therapy

    OpenAIRE

    2016-01-01

    Growth hormone replacement therapy (GHRT) increases exercise capacity and insulin resistance while it decreases fat mass in growth hormone-deficient patients (GHD). Ectopic lipids (intramyocellular (IMCL) and intrahepatocellular lipids (IHCL) are related to insulin resistance. The effect of GHRT on ectopic lipids is unknown. It is hypothesized that exercise-induced utilization of ectopic lipids is significantly decreased in GHD patients and normalized by GHRT. GHD (4 females, 6 males) and age...

    Ectopic variceal bleeding is a rare (2-5%) but fatal gastrointestinal bleed in patients with portal hypertension. Patients with ectopic variceal bleeding manifest melena, hematochezia, or hematemesis, which require urgent managements. Definitive therapeutic modalities of ectopic varices are not yet standardized because of low incidence. Various therapeutic modalities have been applied on the basis of the experiences of experts or availability of facilities, with varying results. We have encountered eight cases of gastrointestinal ectopic variceal bleeding in five patients in the last five years. All patients were diagnosed with liver cirrhosis presenting melena or hematemesis. All patients were treated with various endoscopic modalities (endoscopic variceal obturation [EVO] with cyanoacrylate in five cases, endoscopic variceal band ligation (EVL) in two cases, hemoclipping in one case). Satisfactory hemostasis was achieved without radiologic interventions in all cases. EVO and EVL each caused one case of portal biliopathy, and EVL induced ulcer bleeding in one case. EVO generally accomplished better results of variceal obturations than EVL or hemoclipping, without serious adverse events. EVO may be an effective modality for control of ectopic variceal bleeding without radiologic intervention or surgery.

    Across the tree of life, species vary dramatically in nuclear genome size. Mutations that add or remove sequences from genomes-insertions or deletions, or indels-are the ultimate source of this variation. Differences in the tempo and mode of insertion and deletion across taxa have been proposed to contribute to evolutionary diversity in genome size. Among vertebrates, most of the largest genomes are found within the salamanders, an amphibian clade with genome sizes ranging from ~14 to ~120 Gb. Salamander genomes have been shown to experience slower rates of DNA loss through small (i.e., salamander genomes resulting from larger deletions. Here, we focus on one type of large deletion-ectopic-recombination-mediated removal of LTR retrotransposon sequences. In ectopic recombination, double-strand breaks are repaired using a "wrong" (i.e., ectopic, or non-allelic) template sequence-typically another locus of similar sequence. When breaks occur within the LTR portions of LTR retrotransposons, ectopic-recombination-mediated repair can produce deletions that remove the internal transposon sequence and the equivalent of one of the two LTR sequences. These deletions leave a signature in the genome-a solo LTR sequence. We compared levels of solo LTRs in the genomes of four salamander species with levels present in five vertebrates with smaller genomes. Our results demonstrate that salamanders have low levels of solo LTRs, suggesting that ectopic-recombination-mediated deletion of LTR retrotransposons occurs more slowly than in other vertebrates with smaller genomes.

    The aim of this study was to review the histology of the upper pole segment in patients with duplex ectopic ureterocele to verify if a less aggressive surgery is justified in the prenatally diagnosed patients. We reviewed the histology of the upper pole segment of 15 consecutive patients with duplex system ectopic ureterocele treated between 1991 and 1999 at the Paediatric Surgery Unit of University Hospital of Messina. The diagnosis of duplex system ectopic ureterocele was made according to the criteria of the Section on Urology of the American Academy of Paediatrics. The histology specimens were assessed for dysplastic, inflammatory and obstructive changes. All 15 patients with duplex system ectopic ureterocele were surgically treated with heminephro-ureterectomy and the surgical specimens were histologically examined. Nine of the 15 patients were prenatally diagnosed. The histology of the upper pole segment of the 9 prenatally diagnosed showed in all patients segmental renal microcystic dysplasia, chondroid metaplasic islands and an inflammatory tubulo-interstitial nephropathy in 6 patients (66.6%) and in 2 (22.2%) nephroblastomatosis. The histology of six the postnatal postnatally diagnosed patients showed in all patients segmental multicystic renal dysplasia, inflammatory tubulo-interstitial nephropathy and segmental parenchymal scars. The upper pole histology of the patients with duplex ectopic ureterocele diagnosed prenatally did not show any evidence of reversible histological change. Considering the histology and the good outcome of patients treated with upper pole nephroureterectomy a less aggressive surgery with preservation of the upper pole does not seem justified.

    The analysis of the surface Electrocardiogram (ECG) is the most extended noninvasive technique in cardiological diagnosis. In order to properly use the ECG, we need to cancel out ectopic beats. These beats may occur in both normal subjects and patients with heart disease, and their presence represents an important source of error which must be handled before any other analysis. This paper presents a method for electrocardiogram ectopic beat cancellation based on Radial Basis Function Neural Network (RBFNN). A train-able neural network ensemble approach to develop customized electrocardiogram beat classifier in an effort to further improve the performance of ECG processing and to offer individualized health care is presented. Six types of beats including: Normal Beats (NB); Premature Ventricular Contractions (PVC); Left Bundle Branch Blocks (LBBB); Right Bundle Branch Blocks (RBBB); Paced Beats (PB) and Ectopic Beats (EB) are obtained from the MIT-BIH arrhythmia database. Four morphological features are extracted from each beat after the preprocessing of the selected records. Average Results for the RBFNN based method provided an ectopic beat reduction (EBR) of (mean ± std) EBR = 7, 23 ± 2.18 in contrast to traditional compared methods that, for the best case, yielded EBR = 4.05 ± 2.13. The results prove that RBFNN based methods are able to obtain a very accurate reduction of ectopic beats together with low distortion of the QRST complex.

    Ectopic liver and gallbladder are rare anomalies usually not accompanied by any symptoms and are found during surgical exploration or autopsy. We aimed to find a cause of this anomaly using somatic cell nuclear transfer (SCNT) technology, which can produce genetically identical organisms. A cloned beagle having ectopic organs was produced and died on the day of birth. Major and ectopic organs were fixed and underwent histologic analysis. SCNT was performed using cells derived from the dead puppy to produce reclones. Normality of internal organs in the original donor dog and recloned dogs was evaluated by computed tomography. While a liver without the gallbladder was located in the abdominal cavity of the cloned dog, a well-defined, reddish brown mass with a small sac was also positioned outside of the thoracic cavity. Histologically, they presented as normal liver and gallbladder. Five reclones were produced, and computed tomography results revealed that the original donor dog and reclones had normal liver and gallbladder structure and location. This is the first report of both ectopic liver and gallbladder in an organism and investigation on the etiology of these abnormalities. Normal organ structure and position in the original donor dog and reclones suggests that the ectopic liver and gallbladder is a possible nonheritable anomaly.

    Full Text Available Background. One of the treatment modalities for ectopic pregnancy is methotrexate. The purpose of this study is to identify the failure rate of methotrexate in treating patients with ectopic pregnancy as well as the risk factors leading to treatment failure. Methods. A retrospective chart review of 225 patients who received methotrexate as a primary management option for ectopic pregnancy. Failure of single dose of methotrexate was defined as drop of BHCG level less than or equal to 14% in the seventh day after administration of methotrexate. Results. 225 patients had methotrexate. Most of the patients (151 (67% received methotrexate based on the following formula: f 50 mg X body surface area. Single dose of methotrexate was successful in 72% (162/225 of the patients. 28% (63/225 were labeled as failure of single dose of methotrexate because of suboptimal drop in BhCG. 63% (40/63 of failure received a second dose of methotrexate, and 37% (23/63 underwent surgical treatment. Among patient who received initial dose of methotrexate, 71% had moderate or severe pain, and 58% had ectopic mass size of more than 4 cm on ultrasound. Conclusion. Liberal use of medical treatment of ectopic pregnancy results in 71% success rate.

    Many countries have witnessed a disturbing increase in cases of Chlamydia trachomatis infection despite enhanced control programs. Since the goal of Chlamydia control is to prevent reproductive complications such as pelvic inflammatory disease and ectopic pregnancy, an understanding of recent trends in these conditions is needed to fully evaluate the effect of control efforts. We analyzed 2 provincial, comprehensive health services administrative databases (encompassing hospitalizations and all physician-delivered services) for pelvic inflammatory disease and ectopic pregnancy trends from 1992 through 2009 in women of reproductive age in British Columbia, Canada. Trends were compared to provincial Chlamydia surveillance data by time-series analysis, using the cross-correlation function method and Granger causality testing. Chlamydia cases substantially increased from 1992 through 2009. Inpatient, outpatient, and total diagnoses of pelvic inflammatory disease and ectopic pregnancy declined from 1992 through 2003. After 2003, pelvic inflammatory disease rates continued to fall, while ectopic pregnancy rates significantly increased. The male Chlamydia urethritis rate increased from 39.4 to 173.6 cases/100,000 from 1996 to 2009. In the context of increasing Chlamydia infection rates, the reproductive complications of Chlamydia infection in women are declining overall. A recent increase in rates of ectopic pregnancies is cause for concern.

    Ectopic thyroid tissue remains a rare developmental abnormality involving defective or aberrant embryogenesis of the thyroid gland during its passage from the floor of the primitive foregut to its usual final position in pre-tracheal region of the neck. Its specific prevalence accounts about 1 case per 100.000-300.000 persons and one in 4.000-8.000 patients with thyroid disease show this condition. The cause of this defect is not fully known. Despite genetic factors have been associated with thyroid gland morphogenesis and differentiation, just recently some mutation has been associated with human thyroid ectopy. Lingual region in the most common site of thyroid ectopy but ectopic thyroid tissue were found in other head and neck locations. Nevertheless, aberrant ectopic thyroid tissue has been found in other places distant from the neck region. Ectopic tissue is affected by different pathological changes that occur in the normal eutopic thyroid. Patients may present insidiously or as an emergency. Diagnostic management of thyroid ectopy is performed by radionuclide thyroid imaging, ultrasonography, CT scan, MRI, biopsy and thyroid function tests. Asymptomatic euthyroid patients with ectopic thyroid do not usually require therapy but are kept under observation. For those with symptoms, treatment depends on size of the gland, nature of symptoms, thyroid function status and histological findings. Surgical excision is often required as treatment for this condition.

    Both β adrenergic and muscarinic receptor stimulation independently potentiate arrhythmogenesis. However, the effect of simultaneous stimulation on arrhythmogenesis is not well known. The purpose of this study was to determine the temporal response of arrhythmia risk to individual and combined autonomic agonists. Guinea pig hearts were excised and Langendorff-perfused. The β adrenergic receptor and muscarinic receptor agonists were isoproterenol (ISO, 0.6 μM) and acetylcholine (ACh, 10 μM), respectively. All measurements with agonists occurred over 21 min. ISO induced ectopic activity for the first 8 min. ISO also transiently shortened and then prolonged R-R interval over a similar time course. ACh added after ISO transiently induced ectopic activity for 12 min, while R-R interval invariantly prolonged. ACh alone produced few ectopic beats, while invariantly prolonging R-R interval. In contrast to ISO alone, ISO following ACh significantly increased ectopic activity and shortened R-R interval for the duration of the experiment. Animals aged 17–19 months exhibited sustained arrhythmogenesis while those aged 11–14 did not. When ACh was removed in older hearts while ISO perfused, a transient increase in ectopic activity and decreased R-R interval was observed, similar to ISO alone. These data suggest that pre-treating with and maintaining ACh perfusion can sustain ISO sensitivity, in contrast to ISO perfusion alone. PMID:26539122

    Postoperative junctional ectopic tachycardia is one of the most serious arrhythmias that occur after pediatric cardiac surgery, difficult to treat and better to be prevented. Our aim was to assess the efficacy of prophylactic dexmedetomidine in preventing junctional ectopic tachycardia after pediatric cardiac surgery. A prospective controlled study was carried out on 90 children who underwent elective cardiac surgery for congenital heart diseases. Patients were randomized into 2 groups. Group I (dexmedetomidine group): 60 patients received dexmedetomidine; Group II (Placebo group): 30 patients received the same amount of normal saline intravenously. The primary outcome was the incidence of postoperative junctional ectopic tachycardia. Secondary outcomes included bradycardia, hypotension, vasoactive inotropic score, ventilation time, pediatric cardiac care unit stay, length of hospital stay, and perioperative mortality. The incidence of junctional ectopic tachycardia was significantly reduced in the dexmedetomidine group (3.3%) compared with the placebo group (16.7%) with P0.005). Prophylactic use of dexmedetomidine is associated with significantly decreased incidence of postoperative junctional ectopic tachycardia in children after congenital heart surgery without significant side effects. © 2017 The Authors.

    We sought to evaluate the global success rate of intramuscular methotrexate for the treatment of ectopic pregnancy, identify factors predictive of treatment success or failure, and study methotrexate tolerability in a large patient cohort. For this single-center retrospective observational study, we retrieved the records of all women who had a clinically or echographically confirmed ectopic pregnancy with a Fernandez score ectopic pregnancy. The medical treatment protocol was effective for 314 patients, i.e., an overall success rate of 78.5%. A single methotrexate dose was sufficient for 63.5% of the women and a second dose was successful for 73.2% of the remaining women. The medical treatment success rate fell as initial hCG levels climbed. The main factors associated with methotrexate failure included day (D) 0, D4 and D7 hCG levels, pretherapeutic blood progesterone, hematosalpinx at D0 and pain at D7. Early favorable kinetics of hCG levels was predictive of success. Methotrexate treatment was successful in 90% of women who had D0 hCG ectopic pregnancy was 80.7%. In this study, we showed that an initial hCG value ectopic pregnancy by methotrexate, and hematosalpinx and pretherapeutic blood progesterone >5ng/ml at diagnosis were predictive of its failure. We also confirmed good tolerability for single-dose methotrexate protocols. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Racial disparities in receipt of a laparoscopic operation for ectopic pregnancy are attributed to inequalities in access to care. This study sought to determine if racial disparities in laparoscopic operation for ectopic pregnancy exist among a universally insured population. Using 2006-2010 TRICARE (insurance for members of the United States Armed Services and their dependents) data, patients who received a laparoscopic operation or laparotomy for ectopic pregnancy were stratified into direct/military or purchased/civilian system of care. Odds of receipt of a laparoscopic operation in each racial group were compared adjusting for patient demographics, system of care, and severity of ectopic pregnancy. Among 3,041 patients in the study sample, 1,878 (61.7%) received laparotomy and 1,163 (38.2%) received a laparoscopic operation within 30 days of diagnosis. Overall, 42.4% of white women received a laparoscopic operation compared with 33.1% of Asian women and 34.9% of black women (P ectopic pregnancy despite universal insurance coverage within civilian/purchased care. Further work is warranted to better understand the factors other than insurance access that may contribute to racial disparities in selection of operative approach. Copyright © 2016 Elsevier Inc.

    Background. One of the treatment modalities for ectopic pregnancy is methotrexate. The purpose of this study is to identify the failure rate of methotrexate in treating patients with ectopic pregnancy as well as the risk factors leading to treatment failure. Methods. A retrospective chart review of 225 patients who received methotrexate as a primary management option for ectopic pregnancy. Failure of single dose of methotrexate was defined as drop of BHCG level less than or equal to 14% in the seventh day after administration of methotrexate. Results. 225 patients had methotrexate. Most of the patients (151 (67%)) received methotrexate based on the following formula: f 50 mg X body surface area. Single dose of methotrexate was successful in 72% (162/225) of the patients. 28% (63/225) were labeled as failure of single dose of methotrexate because of suboptimal drop in BhCG. 63% (40/63) of failure received a second dose of methotrexate, and 37% (23/63) underwent surgical treatment. Among patient who received initial dose of methotrexate, 71% had moderate or severe pain, and 58% had ectopic mass size of more than 4 cm on ultrasound. Conclusion. Liberal use of medical treatment of ectopic pregnancy results in 71% success rate.

    To report a rare case of primary hyperparathyroidism presenting with hyperparathyroid crisis due to parathyroid hyperplasia with ectopic glands. We present the initial clinical manifestations, laboratory results, radiologic and surgical findings, and management in a patient who had hyperparathyroid crisis. The pertinent literature and management options are also reviewed. A 60-year-old female presented with hyperparathyroid crisis requiring preoperative stabilization with rehydration, diuresis, bisphosphonate therapy, and ultimately hemodialysis. Parathyroidectomy revealed asymmetric 4-gland hyperplasia, with a massive ectopic parathyroid gland in the tracheoesophageal groove extending into the mediastinum. Her postoperative course was complicated by hungry bone syndrome and hypocalcemia. This case illustrates the rare occurrence of hyperparathyroid crises due to asymmetric parathyroid hyperplasia with a massive ectopic parathyroid gland.

    Ectopic adrenocorticotropic hormone (ACTH) is rarely secreted by neuroendocrine tumors. Although neuroendocrine tumors may occur at any site in the gastrointestinal system, they very rarely occur in the ampulla of Vater and have a poor prognosis. The present study described the first Cushing's syndrome as a result of ectopic ACTH arising from the ampulla of Vater neuroendocrine carcinoma. A 69-year-old female was admitted with clinical features of Cushing's syndrome, confirmed biochemically by hypokalemia, and elevated levels of ACTH and cortisol. In further investigations, a tumor of the ampulla of Vater and liver metastases were detected. Pathological analysis of the biopsy confirmed a neuroendocrine carcinoma, which was immunohistochemically positive for chromogranin A, synaptophysin, cluster of differentiation 56 and ACTH. Therefore, the present study diagnosed a functional and metastatic neuroendocrine carcinoma of the ampulla of Vater with ectopic ACTH production causing Cushing's syndrome. The patient succumbed to mortality 4 months later, despite administration of combined chemotherapy with irinotecan and cisplatin. PMID:27330779

    Full Text Available Ectopic Choriocarcinoma is an extremely rare occurrence. The case of ectopic choriocarcinoma discussed here involved a 12 year old girl who presented with lower abdominal pain and dizziness following a short period of amenorrhea after attaining menarche. Aprovisional diagnosis of ruptured ectopic gestation was made based on the clinical evaluation and patient had emergency laparotomy. Histopathology report revealed a choriocarcinoma of the ovary. Patient defaulted on subsequent follow up care. This case is presented as an eye opener on the need to also focus on the reproductive health challenges, early sex education in preteen and rare occurrence of the disease amongst the Pre-teenage groups. It is also important to deal with the possibility of a non gestational choriocarcinoma of the ovary which has a worse prognosis.

    Ectopic pregnancy is a very dangerous complication of pregnancy, affecting 1%-2% of all reported pregnancies. Due to ethical constraints on human biopsies and the lack of suitable animal models, there has been little success in identifying functionally important genes in the pathogenesis of ectopic pregnancy. In the present study, we developed a random walk-based computational method named TM-rank to prioritize ectopic pregnancy-related genes based on text mining data and gene network information. Using a defined threshold value, we identified five top-ranked genes: VEGFA (vascular endothelial growth factor A), IL8 (interleukin 8), IL6 (interleukin 6), ESR1 (estrogen receptor 1) and EGFR (epidermal growth factor receptor). These genes are promising candidate genes that can serve as useful diagnostic biomarkers and therapeutic targets. Our approach represents a novel strategy for prioritizing disease susceptibility genes.

    The objective of the present study is to describe key computed tomography and magnetic resonance imaging findings in patients with acute abdominal pain caused by ectopic pregnancy. For this purpose, two radiologists consensually selected and analyzed computed tomography and magnetic resonance imaging studies performed in female patients with acute abdominal pain caused by proven ectopic pregnancy in the period between January 2010 and December 2011. The imaging diagnosis of ectopic pregnancy is usually obtained by ultrasonography, however, with the increasing use of computed tomography and magnetic resonance imaging in the assessment of patients with acute abdomen of gynecological origin it is necessary that the radiologist becomes familiar with the main findings observed at these diagnostic methods.

    Full Text Available We report two cases of 27-year-old and 19-year-old female patients with ectopic neurohypophysis and panhypopituitarism due to absent pituitary stalk. They were admitted to the endocrinology clinic with short stature, growth retardation and primary amenorrhea. Basal hormones revealed secondary hypothyroidism, adrenal insufficiency, hypogonadism and growth hormone insufficiency. Peak cortisol response to the short synacthen test (SST was normal but was inadequate to insulin tolerance test. The other dynamic pituitary function tests showed panhypopituitarism. Magnetic resonance imaging of the pituitary gland revealed an ectopic posterior pituitary tissue and absent pituitary stalk. We administered hormone replacement therapy. As this disorder is usually encountered in the pediatric age group, we report here two adult patients with ectopic posterior pituitary tissue, absent pituitary stalk and panhypopituitarism.

    Full Text Available OBJECTIVE: To study the incidence and relevance of ectopic adrenal tissue in pediatric patients who underwent groin surgical explorations. MATERIALS AND METHODS: We studied 1120 patients with groin surgical explorations during a period of 8 consecutive years. Patients’ clinical data and histological findings were analyzed. RESULTS: We found ectopic adrenal tissue in 13 patients in 1120 groin surgical exploration (1.16%. Of the 13 cases, 5 were diagnosed as having undescended testes, 6 inguinal hernia and 2 communicating hydrocele. Median age at diagnosis was 5.6 years. Histological sections showed adrenal cortical tissue with no medulla present. CONCLUSION: Based on the clinical implications of those adrenal rests it is mandatory the removal of this ectopic tissue whenever encountered during surgical interventions in the groin region in children.

    Ectopic liver tissue is a rare clinical entity that is mostly asymptomatic and found incidentally. In certain situations, however, patients may present with symptoms of abdominal pain secondary to torsion, compression, obstruction of adjacent organs, or rupture secondary to malignant transformation. Herein, we report a case of a 25-year-old female that presented with acute onset of epigastric pain found to have ectopic liver tissue near the gallbladder complicated by acute hemorrhage necessitating operative intervention in the way of laparoscopic excision and cholecystectomy. The patient\\'s postoperative course was uneventful. Gross pathology demonstrated a 1.2 x 2.8 x 4.5 cm firm purple ovoid structure that histologically revealed extensive hemorrhagic necrosis of benign ectopic liver tissue.

    2012-01-01

    Full Text Available Introduction : Maxillary permanent first molars are frequently found ectopic teeth in mixed dentition. If left untreated, it may cause serious sequel including early loss of the primary second molar, space loss, and impaction of second premolars. Clinical Innovation: This article describes a new successful innovative method for the correction of ectopically erupting maxillary first permanent molar in an 8-year-old boy. Discussion: Early correction of ectopically erupting permanent molars is an integral part of interceptive orthodontics. Several treatment methods have been suggested. Among these, the interproximal wedging techniques are the simplest but are not always appropriate or feasible. The other treatment modalities may be either complicated, expensive, or require impression taking, appliance delivery, and activation appointments. The following case illustrates a new chairside technique that eliminates the need of impression taking, appliance delivery, and activation appointments and is very simple.

    2007-01-01

    Full Text Available Objective. To evaluate serum chlamydia antibody titers (CATs in tubal occlusion or previous ectopic pregnancy and the associated risk factors. Methods. The study population consisted of 55 women wih tubal damage and 55 parous women. CAT was measured using the whole-cell inclusion immunofluorescence test and cervical chlamydial DNA detected by PCR. Odds ratios were calculated to assess variables associated with C. trachomatis infection. Results. The prevalence of chlamydial antibodies and antibody titers in women with tubal occlusion or previous ectopic pregnancy was significantly higher (P<.01 than in parous women. Stepwise logistic regression analysis showed that chlamydia IgG antibodies were associated with tubal damage and with a larger number of lifetime sexual partners. Conclusions. Chlamydia antibody titers were associated with tubal occlusion, prior ectopic pregnancy, and with sexual behavior, suggesting that a chlamydia infection was the major contributor to the tubal damage in these women.

    Full Text Available More than 99% of patients with acromegaly harbor a growth hormone (GH secreting pituitary adenoma. As the time from onset of signs/symptoms to diagnosis of acromegaly is long (symptom onset to diagnosis is often 4-10 years, pituitary adenomas that cause GH excess are often large and are nearly always visible on conventional magnetic resonance imaging (MRI. However, in rare circumstances, acromegalic patients without an ectopic source will not have imaging evidence of a pituitary adenoma. Management of these patients poses special challenge, and once ectopic source of GH/growth-hormone-releasing hormone (GHRH is ruled out, an exploration of pituitary might be useful. We herein report a case of acromegaly with imaging evidence of sellar floor osteoma, but no pituitary adenoma, and negative work up for an ectopic source of GH/GHRH tumor, and on surgical exploration pituitary adenoma could be identified and removed and confirmed on histopathologic examination.

    Increased human chorionic gonadotropin levels (HCG) can be detected in femoral blood, bile, and vitreous humor collected during autopsy of pregnant women using a standard kit designed for living patients. In the study herein, the concentrations of HCG were measured in postmortem serum, vitreous, bile, cerebrospinal, and pericardial fluids in 4 cases of fatal ectopic pregnancy and 40 controls using a quantitative electrochemiluminescence immunoassay designed for living patients. No false-negative cases were identified in any of the analyzed samples in any of the ectopic pregnancy cases. No correlations were found between total HCG levels in postmortem serum and the other tested specimens. The results of this study would suggest that higher HCG in bile, vitreous, pericardial, and cerebrospinal fluids may confirm the existence of ectopic pregnancy and therefore identify other situations in which this hormone is increased, although gestational age cannot be reliably estimated using these values. © 2015 American Academy of Forensic Sciences.

    Background: Ectopic eruption of a tooth or osteoma rarely occurs within the maxillary sinus. Coexistence of these two rare entities in the maxillary sinus has never been reported in the English literature. Case Report: Herein, we present a 21 year-old male patient with osteoma and ectopic tooth in the left maxillary sinus treated with the removal of the ectopic tooth by endoscopic sinus surgery and excision of the osteoma by the Caldwell-Luc procedure. Conclusion: Unique coexistence of two different entities in the maxillary sinus is most likely due to pediatric facial trauma. Pediatric patients with maxillofacial trauma should be carefully watched for dental injury both clinically and radiologically. PMID:27606148

    Full Text Available Developmental abnormalities of the thyroid gland are very rare. The most common abnormalities include ectopic thyroid tissues that are commonly seen in lingual or sublingual location, agenesis, and hemiagenesis of the thyroid gland. These developmental defects may or may not be associated with thyroid dysfunction. Our case is an 18-year-old male who presented with swelling in the neck of 4-year duration. Clinical examination revealed an oval-shape swelling in the left side of the thyroid gland. The ultrasound and the nuclear scan report revealed the presence of thyroid hemiagenesis of the right lobe with isthmus along with double ectopic thyroid tissue at suprahyoid and infrahyoid region. His thyroid function test showed elevated thyroid-stimulating hormone (TSH and normal free T4. We report a very rare case of thyroid hemiagenesis with double ectopic thyroid tissue; and to the best of our knowledge, this is the first report in the world literature.

    Full Text Available Abstract Background The manifestation of primary hyperparathyroidism with acute pancreatitis is a rare event. Ectopic paraesophageal parathyroid adenomas account for about 5%–10% of primary hyperparathyroidism and surgical resection results in cure of the disease. Case presentation A 71-year-old woman was presented with acute pancreatitis and hypercalcaemia. During the investigation of hypercalcemia, a paraesophageal ectopic parathyroid mass was detected by computerized tomography (CT scan and 99mTc sestamibi scintigraphy. The tumor was resected via a cervical collar incision and calcium and parathormone tumor levels returned to normal within 48 hours. Conclusions Acute pancreatitis associated with hypercalcaemia should pose the suspicion of primary hyperparathyroidism. Accurate preoperative localization of an ectopic parathyroid adenoma, by using the combination of 99mTc sestamibi scintigraphy and CT scan of the neck and chest allows successful surgical treatment.

    The centromere-specific histone variant CENP-A (CID in Drosophila) is a structural and functional foundation for kinetochore formation and chromosome segregation. Here, we show that overexpressed CID is mislocalized into normally non-centromeric regions in Drosophila tissue culture cells and animals. Analysis of mitoses in living and fixed cells reveals that mitotic delays, anaphase bridges, chromosome fragmentation, and cell and organismal lethality are all direct consequences of CID mislocalization. In addition, proteins that are normally restricted to endogenous kinetochores assemble at a subset of ectopic CID incorporation regions. The presence of microtubule motors and binding proteins, spindle attachments, and aberrant chromosome morphologies demonstrate that these ectopic kinetochores are functional. We conclude that CID mislocalization promotes formation of ectopic centromeres and multicentric chromosomes, which causes chromosome missegregation, aneuploidy, and growth defects. Thus, CENP-A mislocalization is one possible mechanism for genome instability during cancer progression, as well as centromere plasticity during evolution.

    Ectopic bone formation after joint replacement or brain injury in humans is a serious complication that causes immobility of joints and severe pain. However, mechanisms underlying such ectopic bone formation are not fully understood. Bone morphogenetic protein (BMPs) are defined as inducers of ectopic bone formation, and they are regulated by several types of inhibitors. ANA is an antiproliferative molecule that belongs to Tob/BTG family, but its activity in bone metabolism has not been known. Here, we examined the role of ANA on ectopic bone formation activity of BMP. In ANA-deficient and wild-type mice, BMP2 was implanted to induce ectopic bone formation in muscle. ANA deficiency increased mass of newly formed bone in vivo compared with wild-type based on 3D-muCT analyses. ANA mRNA was expressed in bone in vivo as well as in osteoblastic cells in vitro. Such ANA mRNA levels were increased by BMP2 treatment in MC3T3-E1 osteoblastic cells. Overexpression of ANA suppressed BMP-induced expression of luciferase reporter gene linked to BMP response elements in these cells. Conversely, ANA mRNA knockdown by small interference RNA enhanced the BMP-dependent BMP response element reporter expression. It also enhanced BMP-induced osteoblastic differentiation in muscle-derived C2C12 cells. Immunoprecipitation assay indicated that ANA interacts with Smad8. Thus, ANA is a suppressor of ectopic bone formation induced by BMP, and this inhibitory ANA activity is a part of the negative feedback regulation of BMP function.

    Ectopic thyroid-stimulating hormone (TSH)-secreting pituitary adenomas are rare and can often be misdiagnosed as primary hyperthyroidism. We present a case of an ectopic suprasellar TSH-secreting pituitary adenoma. A literature review of previously reported ectopic TSH-secreting and suprasellar pituitary adenomas is included to illustrate the clinical characteristics of this disease entity and the diversity of operative approaches to treating ectopic suprasellar pituitary adenomas. A 46-year-old man presented with typical clinical signs of hyperthyroidism and a history of progressive visual field impairment and vision loss. Laboratory investigations revealed that the patient had elevated levels of free thyroxine and free triiodothyronine and a normal level of TSH. Neuro-ophthalmologic examination showed right eye/left eye = 1.0/0.6 and left temporal hemianopia. Magnetic resonance imaging revealed a mass located in the suprasellar space. The patient underwent preoperative short-term octreotide treatment followed by gross total resection of the tumor via the extended endoscopic endonasal transtuberculum sellar approach. At 6-month follow-up evaluation, the patient's endocrinologic function tests met the criteria for cure, and magnetic resonance imaging revealed a normal pituitary gland and stalk with no tumor recurrence. Histologic diagnosis confirmed the presence of a TSH-secreting pituitary adenoma. To the best of our knowledge, this is the first reported case of an ectopic suprasellar TSH-secreting pituitary adenoma. Preoperative preparation and complete resection are the keys to a cure. The extended endoscopic endonasal transtuberculum sellar approach is an alternative minimally invasive method for the removal of an ectopic suprasellar pituitary adenoma.

    Although all ectopic pregnancies are associated with risk of hemorrhage, cornual pregnancies are feared for catastrophic hemorrhage and uncontrollable bleeding. The maternal mortality rate can be as high as 2.5%, which is 7 times higher than the mortality rate for ectopic pregnancies in general. Different techniques have been used to control hemostasis, including purse string suture, square suture, endo-loop, electrocoagulation, and devascularization. Injection of vasopressin into the uterus is a simple method that greatly reduces the blood loss at cornuostomy. A step by step demonstration of the surgical procedure (Canadian Task Force classification III). Hospital. A 32-year-old woman, G7P3L3A3 (Gravida 7, Para 3, Living 3, Abortion 3), with 4 months of amenorrhea, was diagnosed with a cornual ectopic pregnancy. She was treated with 200 mg mifepristone and 800 μg misoprostol. She had undergone dilatation and curettage twice and was referred for persisting cornual ectopic pregnancy. At laparoscopy, 20 U injection vasopressin in 100 mL .9% normal saline was injected into the myometrium of the uterus. Incision was made over the ectopic pregnancy with ultrasonic energy and the ectopic pregnancy enucleated using suction apparatus and ultrasonic energy. Hemostasis was ensured and the bed sutured with barbed suture. Surgery duration was 1 hour, and blood loss was 200 mL. Institutional review board and ethics committee approval was obtained. Injection of vasopressin into the uterus significantly reduces blood loss, operative time, and patient morbidity and mortality at laparoscopic cornuostomy. Copyright © 2017 AAGL.

    Ectopic pregnancy is a medical emergency. The classic treatment for this condition is surgery but early diagnosis allows for non-surgical treatment. In recent years, intramuscular methotrexate has been considered, due to easy administration, its less invasive nature and low complications, but there are arguments about its effects. The aim of this study was to evaluate tubal patency after treatment of ectopic pregnancy with methotrexate and related factors. This cross-sectional study was conducted on 80 women with ectopic pregnancy who were admitted to Sanandaj Be'sat Hospital in 2014. Patients who had successful treatment for ectopic pregnancy with single or multiple doses of methotrexate 50 mL/m(2) were enrolled. Three to 6 months after treatment, the patients were evaluated for tubal patency by hysterosalpingography. Data were analyzed using spss, t-tests, χ(2) -test and logistic regression. The tubal patency rate after treatment of ectopic pregnancy with methotrexate was 75% in hysterosalpingography. The average size of the ectopic pregnancy mass of women with open fallopian tubes was 22.5 ± 7.0 mm and for women with closed fallopian tubes it was 34.7 ± 10.0 mm (P = 0.0001). β-human chorionic gonadotropin levels were 642.1 ± 850.5 in women with open fallopian tubes and 3816.3 ± 4487.3 for women with closed fallopian tubes (P = 0.0001). There was no significant correlation statistically between tubal patency with a history of stillbirth and number of pregnancies (P > 0.5). There was a statistically significant relation between tubal patency and the number of births and also methotrexate dose (P ectopic pregnancy with methotrexate is effective for saving tubal patency. Levels of human chorionic gonadotrophin-β ectopic pregnancy mass size smaller than 33.5 mm are significant predictors of tubal patency. © 2015 Japan Society of Obstetrics and Gynecology.

    replication stress translates into mitotic defects and genomic instability. Arrest of cell growth and induction of DNA double-strand breaks was also observed in MCF7 breast cancer cells in response to SSX2 expression. Additionally, MCF7 cells with ectopic SSX2 expression demonstrated typical signs...... of SSX2 expression in melanoma cell lines demonstrated that SSX2 supports the growth of melanoma cells. Our results reveal two important phenotypes of ectopic SSX2 expression that may drive/support tumorigenesis: First, immediate induction of genomic instability, and second, long-term support of tumor...

    To determine the outcome of histological examinations of surgical specimens obtained from treatment of tubal ectopic pregnancy and to correlate with clinical findings, pre-operative ultrasound scans and the type of surgery. A retrospective cohort study of 941 women diagnosed with a tubal ectopic pregnancy in the Early Pregnancy Unit and having surgical treatment at King's College Hospital, London. Clinical and ultrasound data had been entered contemporaneously on our electronic early pregnancy database and hospital clinical records over an 11year period from 2004 to 2014. Demographic data, clinical history, ultrasound scan parameters, type of surgical management and histological diagnosis were recorded. The primary outcome measure was the presence or absence of chorionic villi in the surgical specimen. Data were analysed using Mann Whitney U test for non-parametric data, relative risk for categorical data and binomial logistic regression. A surgical specimen was obtained in 925 cases. Of these, 881/925 (95.2%) were positive for the presence of chorionic villi on histological examination. Patients with negative histology had a lower median gestational age, smaller ectopic pregnancies and lower serum human chorionic gonadotrophin levels. The relative risk of negative histology was significantly higher with a solid ectopic pregnancy on ultrasound (RR1.91, 95% CI 1.07-3.4) and with conservative surgery (RR 3.68, 95% CI 1.25-10.77). The relative risk was significantly lower with the presence of embryonic cardiac activity (RR 0.12, 95% CI 0.02-0.85). Only the serum hCG level was a significant predictor of negative histology on logistic regression analysis (p=0.048). In 39/44 women with negative histology, the human chorionic gonadotrophin level declined after surgery with no further intervention. Five of the 44 required a second surgical procedure as the ectopic pregnancy had been missed at the initial surgery and did not resolve. There is lack of histological

    Ectopic thyroid tissue of nasopharynx is an uncommon phenomenon and papillary thyroid carcinoma arising from the tissue is extremely rare. The authors report a rare case of 16-year-old girl with papillary thyroid carcinoma of nasopharynx. Clinicians were ever confused by adenoid hypertrophy and solved the diagnostic dilemma by adequate examinations. In the case, we mainly emphasize that surgeons should be aware of and actively consider such a possibility of ectopic papillary thyroid carcinoma of nasopharynx in children and adolescents with long-term nasal obstruction, even if thyroid carcinoma is a rare tumor.

  9. ACTH overexpressing pituitary hyperplasia in a patient with ectopic ACTH-syndrome due to carcinoid of the lung

    Full Text Available Ectopic ACTH-syndrome is the most diagnostically challenging  variant of endogenous hypercortisolism. Particularly difficult differential diagnosis of this syndrome is from Cushing's disease (CD, as currently there is no single test sufficiently accurate to differentiate accurately ectopic ACTH production from the pituitary. The main functional tests are based on the fact that the vast majority of ectopic ACTH production is autonomous and suppresses one from pituitary. But in some cases this is not observed, and then the data obtained all necessary laboratory and instrumental research evidence in favor of central genesis of CD in a patient with ACTH ectopic secretion, which can lead to inappropriate treatment. If you confirm the ectopic ACTH-syndrome, it may take quite a long time of searching for the pathological focus, as there is no sufficiently precise imaging and diagnostic method for determining the localization of ectopic source of ACTH production. Thus, the differential diagnosis of ACTH-dependent hypercortisolism and localization of the ectopic tumor is the cornerstone of early and radical treatment of patients. We present a difficult clinical case of a patient having a pituitary hyperplasia with excessive ACTH expression with primary ectopic ACTH syndrome caused by lung carcinoid.

    Objective: Ectopic implantation was first reported by Godina in 1986. We herein present 2 cases in which amputated fingers were salvaged and reconstructed by means of temporary ectopic implantation utilizing perforator anastomoses and chimeric flaps. Methods: Case 1. A 30-year-old man injured his right hand. All of the fingers were completely crushed with the exception of the little finger. We performed an ectopic implantation by using the superficial circumflex iliac artery perforator. Three months later, the little finger was transplanted with the superficial circumflex iliac artery perforator flap, vascularized nerve, and the 2nd metacarpal bone. Case 2. A 29-year-old man suffered a degloving injury of the index finger. The digital artery was anastomosed to deep inferior epigastric artery perforator. One month later, a deep inferior epigastric artery perforator flap containing the ectopically transplanted index finger was transplanted, but the index fingertip became pale and necrotized. After debridement, a hemipulp transplantation was performed. Results/Conclusions: As the diameter of perforators is similar to that of digital arteries, and perforators are capable of supplying large areas of tissue, they can be used as recipient vessels for ectopic implantation in finger salvage procedures. Another advantage of perforators as feeding vessels in ectopic implantation is the possibility of forming an ectopic chimera; the finger can be incorporated as a part of the chimeric reconstructive flap. With respect to these advantages, the perforator can be used as a feeder in an ectopic implantation of single finger. PMID:27648114

    Full Text Available Calcium phosphate ceramics with specific physicochemical properties have been shown to induce de novo bone formation upon ectopic implantation in a number of animal models. In this study we explored the influence of physicochemical properties as well as the animal species on material-induced ectopic bone formation. Three bioceramics were used for the study: phase-pure hydroxyapatite (HA sintered at 1200°C and two biphasic calcium phosphate (BCP ceramics, consisting of 60 wt.% HA and 40 wt.% TCP (β-Tricalcium phosphate, sintered at either 1100°C or 1200°C. 108 samples of each ceramic were intramuscularly implanted in dogs, rabbits, and rats for 6, 12, and 24 weeks respectively. Histological and histomorphometrical analyses illustrated that ectopic bone and/or osteoid tissue formation was most pronounced in BCP sintered at 1100°C and most limited in HA, independent of the animal model. Concerning the effect of animal species, ectopic bone formation reproducibly occurred in dogs, while in rabbits and rats, new tissue formation was mainly limited to osteoid. The results of this study confirmed that the incidence and the extent of material-induced bone formation are related to both the physicochemical properties of calcium phosphate ceramics and the animal model.

    Purpose: Patients with deranged renal functions have a number of associated factors which can impair healing of wound and increase postoperative morbidity. This study was conducted to assess the problems while managing ectopic pelvic kidney calculi using laparoscopic approach for percutaneous nephrolithotomy (PCNL) in chronic kidney disease patients. Subjects and Methods: Patients with calculi in ectopic kidney with increased serum creatinine level secondary to obstruction were included in the study. Initially, obstruction was relieved. Patients later underwent laparoscopic-assisted PCNL. Patients were monitored postoperatively. Results: Three patients with large renal calculi in ectopic pelvic kidney had presented in 2 years. Laparoscopic-assisted PCNL was done to remove the stone. Patients had persistent urine leak post-operatively. Mean duration for removal of nephrostomy tube and drain removal were 4.67 days and 6.67 days, respectively. These patients also had paralytic ileus for prolonged duration. Conclusion: Although laparoscopic assisted PCNL is an option in the management of patients with stone disease in ectopic pelvic kidney, prolonged time for healing of tract may increase postoperative morbidity in these patients with impaired renal function.

  15. Ectopic expression of WUS in hypocotyl promotes cell division via GRP23 in Arabidopsis.

    Directory of Open Access Journals (Sweden)

    Dajian Zhang

    Full Text Available WUSCHEL (WUS is essential for preventing stem cell differentiation in Arabidopsis. Here we report that in addition to its functions in meristematic stem cell maintenance, WUS is involved in the regulation of cell division. The WUS gain-of-function mutant, stem ectopic flowers (sef, displayed elongated hypocotyls, whereas the loss-of-function wus-1 mutant had shortened hypocotyls. The long hypocotyl in sef was due to the presence of more cells, rather than increased cell elongation. Microscopic observation, flow cytometry assays, quantitative RT-PCR (qRT-PCR, and histochemical staining of CycB1;1::GUS supported the hypothesis that ectopic cell division occurred in the sef hypocotyls after germination. Both immunoblot and qRT-PCR results showed that WUS was ectopically expressed in sef hypocotyls. Luciferase activity, chromatin immunoprecipitation (ChIP and electrophoretic mobility shift assay (EMSA showed that GLUTAMINE-RICH PROTEIN 23 (GRP23 expression can be activated by WUS and that GRP23 is a direct target gene of WUS. The phenotypes of 35S::GRP23 plants and GRP23 knockdown lines supported the notion that GRP23 mediates the effects of WUS on hypocotyl length. Together, our data suggest that ectopic expression of WUS in hypocotyl controls cell division through its target gene GRP23.

    To explore the diagnostic value of magnetic resonance urography (MRU) in ectopic ureters. Seventeen female children with ectopic ureter were examined by sonography, intravenous urography (IVU), computer tomography (CT), MRU and so on. The mean age of the female children was 4.5 years (7 months approximately 12 years). Seventeen patients were examined by sonography, including 3 dysplasia little kidneys, 1 kidney absence, 12 duplex kidneys with hydroureter, 1 normal.Seven patients were examined by IVV, including 3 hydronephrosis and 4 no image or not clear. Fourteen patients were examined by CT, including 3 dysplasia little kidneys, 11 duplex kidneys with hydronephrosis. Five were determined by cystoscope, including 2 ecto-pic urethral orifices which angiography could only display the expansion of ureter. All children were diagnosed by MRU and an accurate anatomical picture of the entire urinary tract was obtained. To accurately and noninvasively depict the urinary tract and the independence of renal function, MRU may be used for patients with ectopic ureter undiagnosed with sonography and IVU.

  19. Ubiquitin is associated with the survival of ectopic stromal cells in endometriosis

    2004-09-01

    Full Text Available Abstract Background Endometriosis is a condition that affects women of reproductive age, where the glandular and/or stromal tissues from the eutopic endometrium implant in ectopic locations. It is well established that the survival of ectopic implants is due to lower levels of apoptosis, but no consensus exists as to which pathway/s this is mediated by. The ubiquitin protein shares a similar sequence homology to an anti-apoptotic protein called BAG-1 and is expressed in the normal endometrium. Currently, no studies have been conducted to determine ubiquitin expression and its possible anti-apoptotic effects in endometriosis. Methods Archived endometrial tissues from endometriosis patients and women undergoing laparoscopic diagnosis (controls from January 2000 to July 2003 at Westmead Hospital were examined, where 14 cases of endometriosis and 55 controls were included in the study. Results Both the ubiquitin protein and apoptosis were expressed in both glandular and stromal cells throughout the menstrual cycle of the eutopic endometrium, in which ubiquitin exhibited a cyclic expression, reaching a peak in late proliferative phase. In contrast, ubiquitin was predominantly expressed in cells of stromal origin in endometriosis, was no longer regulated by a cyclic pattern and was associated with an aberrant level of cell survival. Conclusions For the first time, this study shows that ubiquitin is expressed in endometriotic cells and may contribute to a reduced sensitivity of ectopic endometrial tissue to apoptosis. These findings also suggest that stromal cells contribute differentially to the development of ectopic endometrial tissue.

    The purpose of this paper is to reinforce the necessity of careful ultrasonographic evaluation of the uterus to detect uterine fusion anomaly in female neonates who were detected as having a unilateral, ectopic, multicystic, dysplastic kidney (MCDK) on fetal US. We detected eight unilateral ectopic MCDK on fetal US of second trimester and neonatal ultrasonography between October 2003 and February 2009; neonatal US were taken at 2 to 10 days after birth for the initial evaluation of MCDK. Uterine fusion anomaly, vaginal obstruction and other associated urogenital anomalies were evaluated by neonatal US. Four of eight female neonates with unilateral ectopic MCDK showed a double uterus on neonatal US. They all showed hemivaginal fluid collection. Obstruction of the hemivagina and vaginal septum were depicted in two cases. A perivaginal cyst was seen in three cases, and in two cases the cyst was connected with the vaginal cavity. An ipsilateral perivaginal tubular structure was seen in one case, which was indicative of a ureteral remnant. There was no associated anomaly in the contralateral kidney except for a tiny cortical cyst in one case. The careful ultrasonographic evaluation of the uterus is important in female neonates who showed the ectopic MCDK on fetal US. In addition, it may help to detect the fusion anomaly that is otherwise difficult to detect on fetal US and to devise a treatment plan to prevent upcoming complications

    2012-01-01

    Full Text Available Ectopic eruption is a concept including those clinical cases in which teeth show abnormal eruption pattern and erupt ectopically, in an incorrect position. This abnormality has been pointed out in the literature for the fi rst permanent molars, mainly the maxillary ones. There is no specifi c etiological factor for this abnormality in the fi rst permanent molar, but different factors are reported. The early approach of the ectopic eruption of the fi rst permanent molar can prevent effects such as the early root resorption of the adjacent deciduous second molar and the loss of space for eruption of the premolar successor as well. The purpose of this paper was to report a ectopic eruption of a maxillary fi rst permanent molar diagnosed in a nine-year-old patient with severe root resorption of the adjacent deciduous second molar. A simple and effective therapeutic approach was implemented to treat such abnormality. This clinical case was followed until complete eruption of the premolar successor.

    Full Text Available Our aim was to evaluate the relationship between the success of methotrexate treatment and β-hCG levels in progressive tubal ectopic pregnancies. We defined a retrospective cohort of 394 progressive tubal ectopic pregnancy patients treated with methotrexate. A single-dose methotrexate protocol using 50 mg/m2 was administered to patients with progressive tubal ectopic pregnancy. Surgery was performed in patients who exhibited signs of acute abdomen due to tubal rupture. Of 394 patients that received methotrexate treatment, 335 (84.6% responded to medical treatment, while the remaining 59 (15.36% underwent surgery due to treatment failure. β-hCG levels in the failure group were significantly higher as compared with the success group at Day 1, Day 4, and Day 7 (2116±3157 vs. 4178±3422, 2062±3551 vs. 4935±4103, and 1532±3007 vs. 3900±4783, respectively. The receiver operating characteristics curve for β-hCG levels at Day 1 was 0.738, with a cutoff value of 1418 mIU/mL, while sensitivity and specificity values reached the optimum for treatment success (83.1% and 59.4%, respectively. Medical treatment with methotrexate achieved an 85.02% success rate for the treatment of progressive tubal ectopic pregnancy, while success rates for medical treatment decreased significantly when initial β-hCG levels were >1418 mIU/mL.

    Ectopic breast tissue, which includes both supernumerary breast and aberrant breast tissue, is the most common congenital breast abnormality. Ectopic breast cancers are rare neoplasms that occur in 0.3% to 0.6% of all cases of breast cancer. We retrospectively report, using a large series of breast abnormalities diagnosed and treated, our clinical experience on the management of the ectopic breast cancer. In 2 decades, we observed 327 (2.7%) patients with ectopic breast tissue out of a total of 12,177 subjects undergoing a breast visit for lesions. All patients were classified into 8 classes, according to the classification of Kajava, and assessed by a physician examination, ultrasounds, and, when appropriate, further studies with fine needle aspiration cytology and mammography. All specimens were submitted to the anatomo-pathologist. The most frequent benign histological diagnosis was fibrocystic disease. A rare granulosa cell tumor was also found in the right anterior thoracic wall of 1 patient. Four malignancies were also diagnosed in 4 women: an infiltrating lobular cancer in 1 patient with a lesion classified as class I, and an infiltrating apocrine carcinoma, an infiltrating ductal cancer, and an infiltrating ductal cancer with tubular pattern, occurring in 3 patients with lesions classified as class IV. Only 1 recurrence was observed. We recommend an earlier surgical approach for patients with lesions from class I to IV. Copyright © 2016 Elsevier Inc. All rights reserved.

    Ectopic pregnancy is the leading cause of pregnancy-related death in the first trimester. Ectopic pregnancy is usually diagnosed by clinical, laboratory, and sonographic findings, with implantation most commonly located in the ampullary part of the fallopian tube. However, pregnancies that develop at unusual implantation sites, such as angular, interstitial, cornual, cervical, ovarian, cesarean scar, and abdominal cavity pregnancies, may rarely occur. Although ultrasound is considered the primary pregnancy-related imaging modality, it may not be able to illustrate the implantation site in certain types of pregnancy. Magnetic resonance imaging (MRI) has gained popularity as an imaging tool for evaluating pregnant patients, and it is used as a problem-solving tool in special circumstances, including ectopic pregnancy. MRI can confirm abnormal implantation site, and distinguish rupture from nonrupture cases before management. Other benefits include absence of ionizing radiation, superb soft tissue contrast, and sensitivity sufficient for identifying hemorrhage and its stages. This article summarizes imaging findings in tubal and non-tubal ectopic pregnancy with an emphasis on the roles and protocols of MRI, key MRI features, and differential diagnosis.

    BACKGROUND: Ectopic pancreas is defined as pancreatic tissue found outside its usual anatomical position, with no ductal or vascular communication with the native pancreas. We describe a case of ectopic pancreas of the small bowel and mesentery causing recurrent episodes of pancreatitis, initially suspected on computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP), and confirmed on histological review of the resection. METHODS: A 67-year-old woman presented with clinical symptoms and biochemical evidence of pancreatitis. She had similar episodes over the past 30 years with unrevealing investi-gations, and was concluded to have idiopathic pancreatitis. She underwent CT and MRCP, with findings suggestive of ectopic pancreas, a diagnosis confirmed on histology of the resection. RESULTS: MRCP identified a mass in the proximal small bowel mesentery isointense to the native pancreas, with a small duct draining into a proximal jejunal loop. The resected specimen consisted of normal parenchyma with lobulated acinar tissue with scattered islets of Langerhans, an occasional ductular structure, and admixed areas of adipose tissue. The patient remained asymptomatic with normal biochemistry six months post-operatively. CONCLUSION: In an individual with abdominal pain, elevated serum amylase/lipase, but imaging findings of a normal native pancreas, ectopic pancreatitis should be considered, and can be evaluated by CT and MRCP.

    Transposable elements are widely distributed and diverse in both eukaryotes and prokaryotes, as exemplified by DNA transposons. As a result, they represent a considerable source of genomic variation, for example through ectopic (i.e. non-allelic homologous) recombination events between transposable element copies, resulting in genomic rearrangements. Ectopic recombination may also take place between homologous sequences located within transposable element sequences. DNA transposons are typically bounded by terminal inverted repeats (TIRs). Ectopic recombination between TIRs is expected to result in DNA transposon inversions. However, such inversions have barely been documented. In this study, we report natural inversions of the most common prokaryotic DNA transposons: insertion sequences (IS). We identified natural TIR-TIR recombination-mediated inversions in 9% of IS insertion loci investigated in Wolbachia bacteria, which suggests that recombination between IS TIRs may be a quite common, albeit largely overlooked, source of genomic diversity in bacteria. We suggest that inversions may impede IS survival and proliferation in the host genome by altering transpositional activity. They may also alter genomic instability by modulating the outcome of ectopic recombination events between IS copies in various orientations. This study represents the first report of TIR-TIR recombination within bacterial IS elements and it thereby uncovers a novel mechanism of structural variation for this class of prokaryotic transposable elements.

    We studied the role of infections in ectopic pregnancy and the different methods of detecting Chlamydia trachomatis infection using serology, cervical and tubal PCR assays, by using a hospital-based, case-control study conducted between November 2007 and September 2009. The sample size was 339 with 113 cases and 226 controls. The cases were women admitted for the management of ectopic pregnancy while the controls were women admitted for spontaneous miscarriage. Both cases and controls were tested for syphilis and chlamydial infection by serology. In addition, cervical samples from controls and both cervical and tubal samples from cases were examined for the presence of chlamydia and gonococcal DNA. Sociodemographic data and past histories were collected using set Proforma. Independent variables for multivariate analysis included previous history of spontaneous abortion, ectopic pregnancy, symptoms of sexully transmitted infections (STI), and use of contraception. Women with a previous history of ectopic pregnancy (adjusted OR 28.3; 95% CI 5.8-138.8; p = 0.01) and a past history of having had symptoms of STI (adjusted OR 11.06; 95% CI 5.45-22.44; p = 0.0005) were significantly more likely to have an ectopic pregnancy than those without such a history. Syphilis serology was positive in 13.3% of ectopic pregnancy cases compared to only 3.5% of controls (crude OR 0.24; 95% CI -0.10-0.58; p = 0.001). From cervical swabs, chlamydia DNA was detected significantly more frequently in cases than controls (8.0% vs 2.2%; crude OR 0.261; 95% CI -0.09-0.80, p = 0.012) but gonorrhea DNA detection rates were not significantly different (3.5% vs 0.9%, crude OR 0.24; 95% CI -0.04-1.35; p = 0.1). Chlamydia was positive in cases only as diagnosed tubal samples for PCR in 17 (15.0%), cervical samples for PCR in 9 (8.0%) and IgM ELISA in 6 (5.3%). Among the three STI tested for in this study, C. trachomatis was the most frequently associated with ectopic pregnancy and was more

    Full Text Available The implantation of the fertilized egg outside the uterine cavity leads to the development of ectopic pregnancy. The incidence of ectopic pregnancy is 1/100 births. The most common place of ectopic implantation of the fertilized ovum is the oviduct (98% with predilection for the ampullar part of the Fallopian tube. The aim of this study was to determine the predictive importance of beta-hCG and progesterone concentration compared to ultrasonographic finding in the ectopic pregnancy diagnosis.We examined 24 patients with ectopic pregnancies which we divided according to the days of amenorrhea into two groups: the first group with the total of 28 patients from 16–42 days and another group of 8 patients with amenorrhea longer than 42 days. The control group was comprised of 20 patients with vital intrauterine pregnancy, gestational age of 42-52 days. Blood samples for quantitative determination of hormones were collected on three occasions after 48 hours in the forenoon time in the examined and control group of pregnant women. Ultrasonographic examinations of all pregnant women were carried out immediately after blood sampling, with the trans-vaginal approach using "make loop" option, and measurements with an accuracy of 0.1 mm.Mean values for beta-hCG range from 698-1774 mlU/ml in the first group of pregnant women, and in the second group of 1896 mlU/ml to 4410 mlU/ml with a statistically significant difference compared to the values in the control group (p <0.001. The concentration of progesterone in the first group of women ranging from 41-70 nmol/l, and in the second group of 76-94 nmol/l which is also the statistically significant difference compared to the control group (p<0.002. We have shown that ultrasonographic finding with its parameters reliably predicts the values of biochemical parameters both in normal intrauterine pregnancy and in the case of ectopic pregnancy.Embryo viability and implantation place condition the values of

    Full Text Available Objectives: Ectopic pregnancy occurs when the embryo fails to implant within the uterine cavity. Methotrexate, a folic acid antagonist has been widely used to treat ectopic pregnancy. The aim of this study is to determine the efficacy of methotrexate treatment for ectopic pregnancies in our settings which will in-turn help us reduce maternal mortality and morbidity.Methods: This was a retrospective review of 60 cases of ectopic pregnancy treated with single dose methotrexate in Nizwa hospital, Oman. Demographic data, clinical presentation, treatment progress, outcome, side effects and future fertility follow up were analysed using a computer database. Selection criteria included hemodynamically stable women with ß-hcg level of ≤5000 mIU/ml, adnexal mass ≤4 cm, absent cardiac activity and hemoperitoneum less than 100 ml. Human chorionic gonadotrophin (hcg assay and clinical presentation were used to determine cases which warranted surgical intervention.Results: The success rate of single dose methotrexate therapy in our study was 65�0(n=39 and 35�0(n=21 required surgical intervention compared to reported success rate of 67-100�0published in various studies. Careful selection of cases and confining strictly to the criteria improved the success rate from 40�0to 60�0in five and half years of the study. The mean average time of resolution of ectopic pregnancy was 32 days for a single dose and 58 days for repeat second or third doses. Eight cases of pregnancy of unknown location were treated successfully with Methotrexate. No major side effects were noted. A successful fertility outcome of 30�0in the first year followed by 13.3�0in the subsequent second year with a secondary infertility rate of 11.6�0was observed in this study.Conclusion: Methotrexate treatment of ectopic pregnancies is safe and effective with no major side effects. Intramuscular methotrexate has the advantage of tubal conservation and saves patients from

    Illustrate laparoscopic technique for resection of cesarean scar ectopic pregnancy, associated with isthmocele repair. Case report SETTING: Tertiary referral centre in Strasbourg, France. The study was approved by the local IRB. Cesarean scar pregnancy is a rare form of ectopic pregnancy. The major risk of this type of pregnancy is the early uterine rupture with massive bleeding and maternal life-threatening. It is therefore crucial to manage actively these pregnancies as soon as they are diagnosed. Therapeutic options can be medical, surgical, or a combination of both. Many case reports or case series are found in the literature, but only few clinical studies, too difficult to carry out because of cases rarity and inconclusiveness. "Systematic review: What is the best first-line approach for cesarean section ectopic pregnancy?" is a meta-analysis that was published in 2016, and includes 194 studies between 1978 and 2014 (126 case reports, 45 cases series and 23 clinical studies). According to this systematic review, hysteroscopy or laparoscopic hysterotomy seems to be the best first-line approach to treat cesarean scar ectopic pregnancy. Uterine artery embolization seems to be reserved for significant bleeding and/or a high suspicion index for arteriovenous malformation. There is however no consensus on treatment of reference. The case concerns a 38-year-old primiparous women with cesarean section in 2010, who was diagnosed by US scan at 7 WG as cesarean scar ectopic pregnancy, confirmed by pelvic MRI. The patient has initially received medical treatment with two intramuscular injections of Methotrexate and one local intra-gestational injection of KCl. Initial rate of HCG was 82000 IU/L. Through a rigorous weekly biological and US scan monitoring, it has been observed an involution of the ectopic pregnancy at ultrasonography associated to HCG decreasing. No bleeding or infectious complications occurred during this period. After 10 weeks of monitoring, because of a

    Full Text Available Introduction. In males the ectopic ureter usualy drains into the prostate (50%. During ureteric developement a thin membrane (Chawalla’s membrane separates the lumen of the ureter and the urogenital sinus at the point where the ureter joins the urogenital sinus. This membrane ruptures allowing urin to drain from the ureter to the urogenital sinus. The authors reported a case of renal dysplasia associated with ipsilateral uretral ectopia mimicking prostatic abscess. Case report. A subfebrile (37.3°C, 23-year-old patient, otherwise healthy, presented with persistent ascending perineal pain non-responsive to antibiotics and analgetics. Digitorectal examination (DRE showed asymmetric prostate with a soft, tender, buldging left lobe suggestive of prostatic abscess. The diagnosis was suspected using transrectal ultrasonography (TRUS, but the picture of the anechoic tubular structure in the left lobe of the prostate with a proximal undefined extraprostatic extension and a caudal intraprostatic blind end was incoclusive for the definitive diagnosis of prostatic abscess. Magnetic resonance imaging (MRI was ordered and definitive diagnosis of renal dysplasia associated with the ipsilateral ectopic ureter filled with inflamed content mimicking prostatic abscess was made. Transurethral incision/minimal resection of the distal, blindly closed end of left ectopic ureter was done. Endoscopic surgical treatment was sufficient for relief of clinical symptoms. The patient’s recovery was uneventful. Conclusion. To the best of our knowledge, a case of renal dysplasia with the ipsilateral ectopic ureter mimicking prostate abscess has not been reported so far. Cystic pelvic malformations in males may result from too craniall sprouting of the ureteral bud, with delayed absorption and ectopic opening of the distal end of the ureter.

    Obesity and overweight are strongly associated with cardiovascular morbidity and mortality. However, there are limited data on the association between excess weight and the risk of ectopic ventricular activity. We investigated the association between body mass index (BMI) and the risk for ectopic ventricular activity (defined as multiple ventricular premature beats (≥3), ventricular bigeminy, nonsustained ventricular tachycardia or sustained ventricular tachycardia) during exercise stress testing among 22,516 apparently healthy men and women who attended periodic health screening examinations between the years 2000 and 2014. All subjects had completed maximal exercise stress testing annually according to the Bruce protocol. Subjects were divided at baseline into three groups: normal weight (BMI ≥ 18.5 kg/m(2) andobese (BMI ≥ 30; N = 2,906). The mean age of study subjects was 47 ± 10 years and 72% were men. Kaplan-Meier survival analysis showed that the cumulative probability for the development of exercise-induced ectopic ventricular activity arrhythmias was highest among obese subjects, intermediate among overweight subjects and lowest among subjects with normal weight (3.4%, 2.7% and 2.2% respectively; p obese subjects were 33% more likely to have ectopic ventricular arrhythmias during exercise compared with subjects with normal weight (p = 0.005), and that each 1 kg/m(2) increase in BMI was associated with a significant 4% (p = 0.002) increased adjusted risk for exercise-induced ventricular arrhythmias. Obesity is independently associated with increased likelihood of ectopic ventricular arrhythmia during exercise. © The European Society of Cardiology 2015.

    Full Text Available BACKGROUND Ectopic pregnancies are increasing in number and proportions. Real increase and better detection methods are contributing for this rise. All the cases diagnosed now are not surgical emergencies. Medical management and expectant line of management are possible. Revised clinical guidelines are there for the selection of cases for nonsurgical management. Knowledge about the risk factors is good for prophylaxis and to have a high suspicion about ectopic pregnancy in high-risk individuals. Knowing the success rate is absolutely essential for counselling before starting the therapy. Aim of the study- 1. To study the risk factor profile of ectopic pregnancies and to compare them with the old data of the study setting. 2. To follow up the cases receiving nonsurgical treatment and to assess the success rate. MATERIALS AND METHODS Study Setting- Department of Obstetrics and Gynaecology, Government Medical College, Kottayam. It is a tertiary care centre with 1500 beds and catering for the population of five districts of Kerala. Study Design- Observational Study Study Period- This study was completed by eighteen months from April 2014 to September 2015. RESULTS 219 cases of ectopic pregnancies were diagnosed during the study period. The ratio of this number with the total number of deliveries during that period is 3.48% and this is three times higher than that of the ratio twenty years ago (1.23%. Risk factor profile is also showing changes over this period. 15.1% had medical treatment and 11% had expectant line of therapy. Success rates are 87.87% and 95.65%, respectively. CONCLUSIONS Incidence and detection of ectopic pregnancies are increasing and the risk factor profile is changing. In properly selected cases, the success of nonsurgical management is excellent.

    Full Text Available Abstract Background Ectopic eruption of teeth in non-dental sites is a rare phenomenon and can present in a variety of ways such as chronic or recurrent sinusitis, sepsis, nasolacrimal duct obstruction, headaches, ostiomeatal complex disease and facial numbness. However, presentation of such patients with recurrent haemoptysis has not been described in the literature so far. We have described a case of an ectopic, supernumerary molar tooth in the maxillary antrum in a patient who initially presented with haemoptysis. Case presentation A 45-year-old male presented with a 2-month history of episodic haemoptysis. A pedunculated growth from the inferior nasal turbinate was seen with fibre-optic visualization. Although the patient was empirically started on antibiotic and anti-allergic therapy, there was no improvement after a few weeks and the patient had recurrent episodes of haemoptysis. Fibre-optic visualization was repeated showing bilateral osteomeatal erythema. Computed tomography scan of the paranasal sinuses demonstrated complete opacification of the left maxillary antrum along with a focal area of density comparable to bone. An ectopic, supernumerary molar tooth was found in the left maxillary antrum on endoscopic examination and subsequently removed. In addition, copious purulent discharge was seen. Post-operatively, the patient was treated with a 10-day course of oral amoxicillin-clavulanate. On follow-up, he reported resolution of symptoms. Conclusion Recurrent haemoptysis has not been described as a presentation for a supernumerary, ectopic tooth in literature before. We recommend that in patients with sinusitis-type of opacification of maxillary antrum and whose condition is refractory to conventional medical treatment, consideration should be given to the investigation of possible underlying anomalies as the cause of such symptoms. Presence of foreign bodies and ectopic teeth in paranasal sinuses can be reliably excluded with the use

    Full Text Available Abstract Background Ectopic mediastinal parathyroid adenomas or hyperplasia account for up to 25% of primary hyperparathyroidism (HPT. Two percent of them are not accessible by standard cervical surgical approaches. Surgical resection has traditionally been performed via median sternotomy or thoracotomy and more recently, via video assisted thoracoscopic surgery (VATS. We present our experience with the novel use of Video-Assisted Mediastinoscopy (VAM for resection of ectopic mediastinal parathyroid glands. Case presentation 4 patients underwent VAM for removal of an ectopic intramediastinal parathyroid gland. All of them had at least one previous unsuccessful neck exploration. In all cases histology confirmed complete resection of ectopic parathyroid glands (3 parathyroid adenomas and one parathyroid hyperplasia. Two of the patients required a partial sternal split to facilitate exploration. Conclusion The cervical approach for resection of ectopic parathyroid adenomas is frequently unsuccessful. Previously, the standard surgical approach in such cases was sternotomy and exploration of the mediastinum. Recently, a number of less invasive modalities have been introduced. We found that VAM has several advantages. It has a short theatre time does not require a complex anaesthetic and is performed with the patient in classic supine position utilising often a previous cervical scar with good cosmetic results. It offers a short hospital stay; it is cost effective with minimal use of fancy and pricy consumables with a comfortable incision and no violation of the pleural space. Additionally the use of digital Video imaging has increased the sensitivity of the mediastinoscopy and has added safety and confidence in performing a detailed mediastinal exploration with an additional great training value as well.

    Ectopic thyroid tissue is a rare entity and when discovered it is typically along the pathway of embryologic migration of the thyroid. We present a case of incidental finding of ectopic thyroid tissue within mediastinum in a 61-year-old female patient with a history of total thyroidectomy for thyroiditis and nodules. The patient presented to emergency room with cough and right chest pain and underwent a chest computed tomographic angiogram (CTA) to exclude pulmonary embolism as part of chest pain workup. One right paratracheal mediastinal soft tissue nodule was visualized on the images of CTA. This right paratracheal soft tissue mass was found to be ectopic benign thyroid tissue by histological analysis of the biopsied tissue samples. The function of this ectopic thyroid tissue was characterized by I-123 radioiodine uptake and single photon emission computed tomography/computed tomography (SPECT/CT) imaging. This case illustrates that ectopic thyroid tissue should be included for differential diagnosis of a hyperdense soft tissue mass located within mediastinum. I-123 SPECT/CT is useful for guiding tissue biopsy of ectopic thyroid tissue distant from orthotopic thyroid gland and functional and anatomic characterization of mediastinal ectopic thyroid tissue for surgical resection when it is medically necessary.

    In-vitro fertilization is a known risk factor for ectopic pregnancies. We sought to establish the risk factors for ectopic pregnancy in GnRH antagonist cycles examining patient and stimulation parameters with an emphasis on ovulation trigger. We conducted a retrospective, cohort study of 343 patients undergoing 380 assisted reproductive technology (ART) cycles with the GnRH antagonist protocol and achieving a clinical pregnancy from November 2010 through December 2015. Significant risk factors for ectopic pregnancy in the univariate analysis included prior Cesarean section (CS), endometriosis, mechanical factor infertility, longer stimulation, elevated estradiol and progesterone levels, GnRH agonist trigger, higher number of oocytes aspirated, and insemination technique. Independent risk factors for ectopic pregnancy in the multivariate analysis included GnRH agonist trigger, higher number of oocytes aspirated, insemination technique, and prior Cesarean section. Excessive ovarian response, IVF (as opposed to ICSI), prior Cesarean section and GnRH agonist trigger were found to be independent risk factors for ectopic pregnancy. Caution should be exercised before incorporating the GnRH agonist trigger for indications other than preventing OHSS. When excessive ovarian response leads to utilization of GnRH agonist trigger, strategies for preventing ectopic pregnancy, such as a freeze all policy or blastocyst transfer, should be considered. Further studies should elucidate whether adjusting the luteal support can reduce the ectopic pregnancy risk.

    Frequent ventricular ectopy on preimplantation Holter has been associated with attenuated benefit from cardiac resynchronization therapy (CRT). However, it is unclear whether ectopic burden measured post-CRT implantation can be utilized to evaluate long-term prognosis. We aimed to describe the association between post-CRT implantation ectopic burden and subsequent risk of clinical outcomes. At the 12-month follow-up visit, 24-hour Holter recordings were performed in 698 CRT-D patients from the MADIT-CRT study. The mean number of ventricular premature complexes (VPCs/hour) was calculated. High ectopic burden was defined as >10 VPCs/hour and low burden as ≤10 VPCs/hour. Multivariate Cox proportional hazards models were utilized to assess the association between 12-month ectopic burden and the risk of the end points of heart failure (HF) or death and ventricular tachyarrhythmias (VT/VF). At 12 months, 282 (40%) patients presented with low ectopic burden and 416 (60%) patients presented with high ectopic burden. The 3-year risk of HF/death and VT/VF was lower in patients with a low burden (7% and 8%) and significantly higher (25% and 24%) in patients with high burden. In multivariate analyses, patients with a high ectopic burden had approximately threefold increased risk of both HF/death (HR=2.76 [1.62-4.70], p ectopic burden at 12-month follow-up was associated with a high 3-year risk of HF/death and VT/VF and threefold increased risk as compared to patients with low burden. Ectopic burden at 12 months may be a valuable approach for evaluating long-term prognosis. © 2017 Wiley Periodicals, Inc.

    We have previously reported that the loss of Arx and/or Pax4 gene activity leads to a shift in the fate of the different endocrine cell subtypes in the mouse pancreas, without affecting the total endocrine cell numbers. Here, we conditionally and ectopically express Pax4 using different cell......, the newly formed alpha cells fail to correct the hypoglucagonemia since they subsequently acquire a beta cell phenotype upon Pax4 ectopic expression. Notably, this cycle of neogenesis and redifferentiation caused by ectopic expression of Pax4 in alpha cells is capable of restoring a functional beta cell...

    Renal duplication accompanied by ureteral ectopia is an uncommon urinary congenital abnormality. We report the case of a 21-year-old girl who suffered from lifelong continuous urinary leakage. She was finally diagnosed with bilateral duplicated collecting systems complicated with right ectopic ureteral orifice - an extremely rare case. The patient underwent ureteric re-implantation for the ectopic side, and her urinary incontinence ceased soon thereafter. In this case, traditional imaging failed to show the exact insertion of an ectopic ureter. However, magnetic resonance urography combined with retrograde intubation radiography successfully depicted the point of ureteric insertion, which may make the diagnostic process accurate and efficient.

    Methods: In this quasi-experimental research, we studied 70 women with ectopic preg-nancies who were treated with MTX, according to a single dose protocol from 2010 to 2013. EP was diagnosed whenever an intrauterine gestational sac was not identified by transvaginal ultrasonography (TVUS, accompanied by an abnormal rise or plateau in human chorionic gonadotropin (beta-hCG concentration. Briefly, women with ectopic pregnancies were considered candidates for MTX treatment if they were hemodynami-cally stable; did not desire surgical therapy, agreed to weekly follow-up; and did not have hepatic, hematologic, or renal disease. A Patient was considered a treatment suc-cess (group 1 if her beta-hCG levels decreased ≤10 m IU/ml after the first dose of MTX. Treatment failure (group 2 was defined as the need for a second or a third dose of MTX or surgery. The following risk factors were compared between the two groups: serum beta-hCG on the days 1 and 4, a ≥ 15% decrease in serum beta-hCG between the days 1-4 of the treatment, age, parity, gravidity, the size of the ectopic mass and the endometrial thickness. Results: The success rate of MTX treatment was 77.1%. There were no significant dif-ferences between the two groups in regard to the age, parity, gravidity, the size of ec-topic mass and the endometrial thickness in vaginal sonography, but the mean serum beta-hCG concentration on days 1 and 4 was lower in the success group than the failure group. We also observed a ≥ 15% decrease in serum beta-hCG in 80.9% of the women from the success group and in 38.5% of the cases whose treatment had failed. The presence of fetal heart activity was seen in only one patient and this patient’s treatment failed. Two patients had previous history of ectopic pregnancy and the treatment of both ended in failure. Conclusion: Among women with ectopic pregnancies who were candidates for MTX treatment, a high serum beta-hCG concentration on the days 1-4 and also a ≤ 15% fall in

    Essential to understanding the process of neuronal signal integration is the knowledge of where within a neuron action potentials (APs) are generated. Recent studies support the idea that the precise location where APs are initiated and the properties of spike initiation zones define the cell's information processing capabilities. Notably, the location of spike initiation can be modified homeostatically within neurons to adjust neuronal activity. Here we show that this potential mechanism for neuronal plasticity can also be exploited in a rapid and dynamic fashion. We tested whether dislocation of the spike initiation zone affects signal integration by studying ectopic spike initiation in the anterior gastric receptor neuron (AGR) of the stomatogastric nervous system of Cancer borealis Like many other vertebrate and invertebrate neurons, AGR can generate ectopic APs in regions distinct from the axon initial segment. Using voltage-sensitive dyes and electrophysiology, we determined that AGR's ectopic spike activity was consistently initiated in the neuropil region of the stomatogastric ganglion motor circuits. At least one neurite branched off the AGR axon in this area; and indeed, we found that AGR's ectopic spike activity was influenced by local motor neurons. This sensorimotor interaction was state-dependent in that focal axon modulation with the biogenic amine octopamine, abolished signal integration at the primary spike initiation zone by dislocating spike initiation to a distant region of the axon. We demonstrate that the site of ectopic spike initiation is important for signal integration and that axonal neuromodulation allows for a dynamic adjustment of signal integration. Although it is known that action potentials are initiated at specific sites in the axon, it remains to be determined how the precise location of action potential initiation affects neuronal activity and signal integration. We addressed this issue by studying ectopic spiking in the axon of
