    A 16-year-old female presented with dribbling of urine along with voluntary voiding since birth. Renal imaging revealed hydroureteronephrosis on the right side; the uterus and ovary were normal. A radionuclide scan showed a left nonfunctional kidney. On cystovaginoscopy, the urethra was shown to be normal and the urinary bladder was tubular with small capacity and an absent trigone. Although the vagina was capacious, no ureteric orifices were found. Computed tomography corroborated the diagnosis of bilateral, single ectopic ureters draining into a grossly dilated vagina. This case is unique because it is a bilateral single-system ureteral ectopia in a completely differentiated female genital tract that presented late in adolescence. To the best of our knowledge, this is the second such ureteral abnormality reported in the literature so far. The patient underwent ileocystoplasty with right ureteric reimplantation and nephroureterectomy for the left nonfunctional kidney, which histopathology showed to be tuberculosis. The patient is continent with cystometric capacity of more than 300 mL. PMID:23878693

    Bilateral adrenalectomy is currently the only available treatment for adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome (ectopic ACTH syndrome) that is refractory to pharmacologic therapy. We describe two patients with refractory ectopic ACTH syndrome who were treated with CT-guided percutaneous microwave ablation of both hyperplastic adrenal glands in a single session: O ne was not a surgical candidate, and the other had undergone unsuccessful surgery. Following the procedure, both patients achieved substantial decreases in serum cortisol, symptomatic improvement, and decreased anti-hypertensive medication requirements.

    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.

    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

    Management of severe ovarian hyperstimulation syndrome (OHSS) includes hospitalization for fluid and electrolyte management. Abdominal paracentesis is also used as minimally invasive form of management in selected cases of severe OHSS following ovulation induction. However, if pregnancy ensues, the syndrome persists for a longer period, and the clinical manifestations of severe OHSS could mask the picture of a bleeding gestational sac. It could be easily overlooked unless the possibility of an ectopic pregnancy is kept in mind in cases of severe OHSS exacerbated by early pregnancy with or without a previous ectopic pregnancy history. We report a case of severe OHSS with simultaneous bilateral tubal pregnancy following intrauterine insemination (IUI). A 31-year-old woman with polycystic ovarian disease developed severe OHSS during the therapeutic course of IUI. An emergent exploratory laparotomy was performed 14 days after admission, and the operative findings showed persistent profuse bleeding from the bilateral fimbrial ends with marked enlargement of the ampullary portions. A linear salpingotomy was performed by a longitudinal incision along the area of maximal distension of the dilated fallopian tubes to preserve her fertility. We recommend that in cases of severe OHSS exacerbated by early pregnancy, serial serum beta-hCG and transvaginal ultrasound follow-up may be necessary due to the potential association of severe OHSS in pregnancy with an ectopic pregnancy.

    Bilateral simultaneous Tubal Ectopic Pregnancy (BTP) is the rarest form of ectopic pregnancy. The incidence is higher in women undergoing assisted reproductive techniques or ovulation induction. The clinical presentation is unpredictable and there are no unique features to distinguish it from unilateral ectopic pregnancy. BTP continues to be a clinician’s dilemma as pre-operative diagnosis is difficult and is commonly made during surgery. Treatment options are varied depending on site of ectopic pregnancy, extent of tubal damage and requirement of future fertility. We report a case of BTP which was diagnosed during surgery and propose an algorithm for management of such patients. PMID:27134950

    2016-01-01

    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. PMID:27134298

    Spontaneous bilateral ectopic pregnancy is the rarest form of ectopic pregnancy. Bilateral tubal pregnancies in the absence of preceding induction of ovulation are a rare occurrence, with an estimated incidence of 1 in 725 to 1 in 1580 ectopicpregnancies. They are usually diagnosed at the time of surgery. We report a case of spontaneous bilateral tubal pregnancies diagnosed intraoperatively. A 33-year-old patient was admitted after light vaginal bleeding, 35 days after her last menstruation. A bilateral salpingectomy was performed without complication and the pathology report confirmed the diagnosis. This is an unusual case of early diagnosis. The diagnosis of bilateral tubal pregnancy is usually madeintraoperatively. This underscores the importance ofidentifying and closely examining both tubes at the time ofsurgery, even in the presence of significant adhesive disease. PMID:26309468

    Congenital bilateral diaphragm agenesis is a very rare condition. We describe limited (abdomen only) autopsy findings of a case of bilateral diaphragm agenesis in a 27-week male fetus with unusual findings of fibrosis of the pancreatic head and ectopic liver nodules in a mass at the upper abdomen that may represent a possible diaphragm anlage. We have correlated our observations with data from experimental and embryological studies to suggest possible mechanisms for the malformations that were present and their implications for our understanding of pancreas, liver and diaphragm development in the human fetus.

    An ectopic tonsil is defined as tonsillar tissue that develops in areas outside of the four major tonsil groups: the palatine, lingual, pharyngeal, and tubal tonsils. The occurrence of tonsillar tissue in the oral cavity in ectopic locations, its prevalence, and its developmental mechanisms that belong to its formation remain unclear. In this report, we describe a rare case of bilateral symmetric ectopic oral tonsillar tissue located at the ventral surface of the tongue along with two solitary cases arising from the floor of the mouth. The role of immune system and its aberrant response leading to ectopic deposits desires further studies. As an ectopic tonsil may simulate a benign soft tissue tumor, this case series highlights the importance of this entity in our clinical differential diagnosis of oral soft tissue masses.

    Ectopic cervical thymus (ECT) is a rare cause of neck mass in the pediatric age group. It is extremely uncommon in infants. Overall more than 100 cases have been reported in the literature, though fewer than 10% involved infants. Furthermore, ECT is usually unilateral and more frequently seen in men than in women. Ultrasound (US) is the preferred initial imaging modality, especially in pediatric neck masses given its wide availability, low cost and lack of radiation exposure. US can show the location, extension, and echotexture of the ECT. Magnetic resonance imaging (MRI) can be performed to verify the diagnosis and confirm communication between the ECT and the mediastinal thymus. Diffusion restriction can aid diagnosis when seen in a neck mass similar to that in the mediastinal thymus. Herein is described a case of bilateral ECT in a 2-month-old boy with associated US and MRI findings. PMID:27463062

  13. Bilateral adrenal cysts and ectopic pancreatic tissue in Beckwith-Wiedemann syndrome: is a conservative approach acceptable?

    PubMed

    2004-06-01

    Beckwith-Wiedemann syndrome is a common overgrowth syndrome associated with an increased risk of neoplasias which might be explained by the nature and localization of the genetic defect. While malignant tumors are often associated with hemihypertrophy, benign tumors are also found. We report a patient with the typical features of Beckwith-Wiedemann syndrome with two histologically different abdominal tumors, bilateral cystic adrenals and ectopic pancreatic tissue present at birth. In both tumors no malignancy could be detected. Ectopic pancreatic tissue is rarely seen and has been described in Beckwith-Wiedemann syndrome only once. After extirpation of the ectopic pancreatic tissue the cystic adrenals were left in situ since macroscopically no normal adrenal tissue could be identified and separated. Regular ultrasound examinations revealed complete resolution of the cystic adrenals within 24 months. Thus it seems that a conservative approach in selected tumors associated with the Beckwith-Wiedemann syndrome might be acceptable.

    Association of single system ectopic ureter with normal functioning bilateral kidney and absence of congenital anomalies is very rarely reported in the literature. We are reporting for the first time a case of this type of anomaly in which uretral ectopia was draining into a Gartner's cyst and was managed by laparoscopy. A 16 year girl presented with normal voiding with continuous dribbling since birth. Voiding cystourethrogram, intravenous urogram, cystovaginoscopy and retrograde contrast study confirmed the diagnosis. Ultrasound of the whole abdomen and physical examination ruled out any associated congenital anomalies. Transperitoneal laparoscopic ureteric reimplantation was performed and distal stump was ligated. On follow-up at 3 months she was completely dry; her vaginoscopy showed disappearance of cystic bulge and her voiding cystourethrogram showed normal study without any reflux. When single system ectopic ureter opens into small-to-moderate size wide opened mouth vaginal Gartner's cyst, laparoscopic ureteric reimplantation and ligation of distal stump is an appropriate procedure.

    Purpose: This retrospective study examined the feasibility and efficacy of bilateral lung radiofrequency ablation (RFA) performed in a single session. Methods: From 2002-2009, patients with bilateral lung metastases were treated by RFA, where possible in a single session under general anesthesia with CT guidance. The second lung was punctured only if no complications occurred after treatment of the first lung. Five lung metastases maximum per patient were treated by RFA and prospectively followed. The primary endpoint was the evaluation of acute and delayed complications. Secondary endpoints were calculation of hospitalization duration, local efficacy, median survival, and median time to tumor progression. Local efficacy was evaluated on CT or positron emission tomography (PET) CT. Results: Sixty-seven patients were treated for bilateral lung metastases with RFA (mean age, 62 years). Single-session treatment was not possible in 40 due to severe pneumothoraces (n = 24), bilateral pleural contact (n = 14), and operational exclusions (n = 2). Twenty-seven (41%) received single-session RFA of lesions in both lungs for 66 metastases overall. Fourteen unilateral and four bilateral pneumothoraces occurred (18 overall, 66.7%). Unilateral (n = 13) and bilateral (n = 2) chest tube drainage was required. Median hospitalization was 3 (range, 2-8) days. Median survival was 26 months (95% confidence interval (CI), 19-33). Four recurrences on RFA sites were observed (4 patients). Median time to tumor progression was 9.5 months (95% CI, 4.2-23.5). Conclusions: Although performing single-session bilateral lung RFA is not always possible due to pneumothoraces after RFA of first lung, when it is performed, this technique is safe and effective.

    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.

    We report on 2 patients with a unilateral vaginal ectopic ureter associated with a single system, ipsilateral hypoplastic pelvic kidney and bicornuate uterus. Although there are many reports of concomitant urinary and reproductive system malformations, a review of the literature shows these unique associations in the same patient to be extremely rare. These findings provide further evidence of the intricate interaction between mesonephric (wolffian) and paramesonephric (müllerian) ducts in the development of the urogenital system. Embryological aspects as well as clinical presentation, diagnostic approach and treatment applicable to this group are discussed.

  1. Ectopic expression of single transcription factors directs differentiation of a medaka spermatogonial cell line.

    2011-08-01

    The capability to form all cell types of the body is a unique feature of stem cells. However, many questions remain concerning the mechanisms regulating differentiation potential. The derivation of spermatogonial cell lines (SGs) from mouse and human, which can differentiate across germ-layer borders, suggested male germ cells as a potential stem cell source in addition to embryonic stem cells. Here, we present a differentiation system using an SG of the vertebrate model organism Oryzias latipes (medaka). We report differentiation of this cell line into 4 different ectodermal and mesodermal somatic cell types. In addition to differentiation into adipocytes by retinoic acid treatment, we demonstrate for the first time that directed differentiation of an SG can be induced by ectopic expression of single transcription factors, completely independent of culture conditions. Transient transfection with mitf-m, a transcription factor that has been shown to induce differentiation into melanocytes in medaka embryonic stem cells, resulted in the formation of the same cell type in spermatogonia. Similarly, the formation of neuron-like cells and matrix-depositing osteoblasts was induced by ectopic expression of mash1 and cbfa1, respectively. Interestingly, we found that the expression of all mentioned fate-inducing transcription factors leads to recapitulation of the temporal pattern of marker gene expression known from in vivo studies.

  3. Ectopic decidua and metastatic squamous carcinoma: presentation in a single pelvic lymph node.

    PubMed

    Cobb, C J

    1988-06-01

    The presence of ectopic decidua in pelvic lymph nodes from patients with squamous carcinoma of the cervix makes evaluation for metastatic disease difficult due to the light microscopic similarity between decidua and sheets of squamous epithelial cells. A patient is present in whom decidualized endometriosis was intimately associated with metastatic moderately differentiate squamous carcinoma in a single pelvic lymph node. This phenomenon afforded an excellent opportunity to study the unique morphologic features that distinguish these two entities. A prior report of this kind was not found. In the absence of obvious squamous differentiation (i.e., intercellular bridges, dyskeratosis, and keratin "pearl" formation), as is frequently the case with squamous carcinoma of the cervix, the light microscopic features that are most useful in distinguishing squamous carcinoma from decidua include the presence of well-defined nests of cohesive cells, nuclear hyperchromasia, and cellular pleomorphism.

    2016-01-01

    Background Surgical treatment is thought to be the most effective strategy for multiple small nodules. However, in general, one-stage bilateral resection is not recommended due to its highly invasive nature. Methods Clinical records of patients undergoing one-stage bilateral resections of multiple pulmonary nodules between January 2009 and September 2014 in a single institution were retrospectively reviewed. Results Simultaneous bilateral pulmonary resection by conventional video-assisted thoracic surgery (VATS) was undertaken in 29 patients. Ground glass opacity (GGO) accounted for 71.9% (46/64) of total lesions, including 26 pure GGO and 20 mixed GGO lesions. One case underwent bilateral lobectomy that was complicated by postoperative dyspnea. Lobar-sublobar (L/SL) resection and bilateral sublobar resection (SL-SL) were conducted in 16 and 12 cases, respectively, and most of these cases had uneventful postoperative courses. There was no significant difference with regard to postoperative complications (P=0.703), duration of use of chest drains (P=0.485), between one- and two-stage groups. Mean postoperative follow-up in cases of primary lung cancer was 31.4 (range, 10–51) months. There was neither recurrence nor deaths at final follow-up. Conclusions Single-stage bilateral surgery in selected cases with synchronous bilateral multiple nodules (SBMNs) is feasible and associated with satisfactory outcomes. PMID:27076942

  7. Ectopic expression of a single homeotic gene, the Petunia gene green petal, is sufficient to convert sepals to petaloid organs.

    PubMed Central

    Halfter, U; Ali, N; Stockhaus, J; Ren, L; Chua, N H

    1994-01-01

    Genetic studies in Arabidopsis and Antirrhinum showed that petal determination requires the concomitant expression of two homeotic functions, A and B, whereas the A function alone determines sepal identity. The B function is represented by at least two genes. The Petunia homeotic gene green petal (gp) is essential for petal determination as demonstrated by a Petunia gp mutant that has sepals instead of petals. We have used ectopic expression of the gp gene as a tool to study flower development in Petunia. CaMV 35S-gp expression leads to homeotic conversion of sepals into petaloid organs when expressed early in development. This demonstrates that a single homeotic gene is sufficient to induce homeotic conversion of sepals to petals, suggesting that other petal determining genes are regulated in part by ectopically expressed gp. Indeed, two other MADS-box-containing genes, pmads 2 and fbp 1, which show homology to the Antirrhinum B function gene globosa, are activated in the converted petal tissue. Furthermore, our data provide evidence for autoregulation of gp expression in the petaloid tissue and uncover the role of gp in fusion of petal tissues. Images PMID:7907980

    A 55-year-old man was treated for Fournier gangrene in 2004 with radical debridement and bilateral testicular transposition to the medial thighs. Eight years later, bilateral hydroceles formed. After conservative measures failed for treatment of the hydroceles, the condition was treated during desired testicular relocation, and creation of a neoscrotum. In the case presented, bilateral thigh hydroceles may have developed from lymphatic injury during testicular transposition. To our knowledge, this is the first case report of bilateral hydrocele testis in the medial thigh pouches following ectopic testicular transposition.

    2016-01-01

    The objective of this study is to report on the short-term radiographic complications and bone healing associated with single-session bilateral tibial tuberosity advancements (TTAs). This retrospective study consists of 74 client-owned dogs with bilateral cranial cruciate ligament rupture that underwent consecutive single-session bilateral TTAs. Radiographs from 74 dogs (148 stifles) were evaluated for evidence of postoperative complications. One hundred forty-three of 148 stifles were scored for radiographic healing using a previously described scoring system. Variables evaluated for a relationship with radiographic complications and healing scores were: breed, age, body weight, sex, and TTA plate type. The overall radiographic complication rate was 17.6% (13/74). Twelve of the 13 radiographic complications were considered to be minor and one was major. Increasing body weight and use of a fork implant were statistically significant factors associated with an increased risk of complication. One hundred forty-three stifle radiographs met the inclusion criteria to be assessed for healing. The mean score was 2.96 out of 4.0. The overall radiographic complication rate and healing scores associated with single-session bilateral TTAs were found to be similar to those described for unilateral TTA.

    Breast reconstruction using free tissue transfer is an increasingly utilised oncoplastic procedure. The aim was to review all bilateral breast reconstructions using abdominal free flaps by a single surgeon over an 11-year period (2003-2014). A retrospective review was performed on all patients who underwent bilateral breast reconstruction using abdominal free flaps between 2003 and 2014 by the senior author (DAM). Data analysed included patient demographics, indication for reconstruction, surgical details, and complications. Fifty-five female patients (mean 48.6 years [24-71 years]) had bilateral breast reconstruction. The majority (41, 74.5%) underwent immediate reconstruction and DIEP flaps were utilised on 41 (74.5%) occasions. Major surgical complications occurred in 6 (10.9%) patients, all of which were postoperative vascular compromise of the flap. Failure to salvage the reconstruction occurred on 3 (5.5%) occasions resulting in a total flap failure rate of 2.7%. Obesity (>30 kg/m(2)) and age > 60 years were shown to have a statistically increased risk of developing postoperative complications (P < 0.05). Our experience demonstrates that abdominal free flaps for bilateral breast reconstruction fares well, with a flap failure rate of 2.7%. Increased body mass index and patient age (>60 years) were associated with higher complication rates. PMID:27504200

    Hearing is of utmost importance for normal speech and social development. Even children who have mild or unilateral permanent hearing loss may experience difficulties with understanding speech, as well as problems with educational and psycho-social development. The increasing advantages of middle-ear implant technologies are opening new perspectives for restoring hearing. Active middle-ear implants can be used in children and adolescents with hearing loss. In addition to the well-documented results for improving speech intelligibility and quality of hearing in sensorineural hearing loss active middle-ear implants are now successfully used in patients with conductive and mixed hearing loss. In this article we present a case of successful, single-stage vibroplasty, on the right side with the fixation of the FMT on the stapes and PORP CLiP vibroplasty on the left side in a 6-year-old girl with bilateral mixed hearing loss and multiple dyslalia associated with Franceschetti syndrome (mandibulofacial dysostosis). CT revealed bilateral middle-ear malformations as well as an atretic right and stenotic left external auditory canal. Due to craniofacial dysmorphia airway and (post)operative, management is significantly more difficult in patients with a Franceschetti syndrome which in this case favoured a single-stage bilateral procedure. No intra- or postoperative surgical complications were reported. The middle-ear implants were activated 4 weeks after surgery. In the audiological examination 6 months after surgery, the child showed 100% speech intelligibility with activated implants on each side.

    Expression of tissue-restricted self-antigens (TRAs) in medullary thymic epithelial cells (mTECs) is essential for self-tolerance induction and prevents autoimmunity, with each TRA being expressed in only a few mTECs. How this process is regulated in single mTECs and coordinated at the population level, such that the varied single-cell patterns add up to faithfully represent TRAs, is poorly understood. Here we used single-cell RNA-sequencing and provide evidence for numerous recurring TRA co-expression patterns, each present in only a subset of mTECs. Co-expressed genes clustered in the genome and showed enhanced chromatin accessibility. Our findings characterize TRA expression in mTECs as a coordinated process, which might involve local re-modeling of chromatin and thus ensures a comprehensive representation of the immunological self.

  16. Sequential bilateral striatal lesions have additive effects on single skilled limb use in rats.

    2007-02-27

    Unilateral dopamine depletion in rats induced by injection of 6-hydroxydopamine (6-OHDA) into the nigrostriatal system causes permanent impairments in limb use. The disturbances in limb use, including impairments in skilled reaching, are most severe on the side contralateral to the lesion. A number of studies, however, have also described ipsilateral deficits in skilled reaching. The purpose of this study was to investigate the effects of sequential bilateral striatal 6-OHDA lesions on skilled reaching movements in rats to compare the contribution of contra- versus ipsilateral motor control. Rats were trained in a reaching task to grasp food pellets with their preferred paw prior to receiving an intrastriatal 6-OHDA injection on the side contralateral to the preferred paw. The lesion significantly reduced reaching success along with qualitative impairments in limb use. In addition, animals displayed asymmetry in limb use and contraversive rotation bias after an apomorphine challenge. Three weeks later, animals received a second lesion induced by intrastriatal 6-OHDA injection into the hemisphere ipsilateral to the preferred paw. This lesion exaggerated the previous impairments in limb use and further reduced reaching success of the preferred paw. In the ladder rung walking task, additional impairments were found only in the forelimb ipsilateral to the first lesion. The findings of additive effects of sequential bilateral lesions suggest that both the contra- and ipsilateral striatum control single limb use. This supports the notion of bilateral control of skilled forelimb use by the mesostriatal dopaminergic system. PMID:17182115

    Object. Video-assisted thoracoscopic sympathectomy is a safe, effective, and minimally invasive procedure for primary hyperhidrosis. This study aims to evaluate long-term results and patients' quality of life and investigate potential variables responsible for compensatory sweating after one-stage bilateral single-port thoracoscopic sympathectomy. Methods. Between 2005 and 2011, 260 consecutive bilateral thoracoscopic sympathectomies were performed in 130 patients for primary palmar and axillary hyperidrosis through one-port access. Residual pain, postoperative complications, recurrence of symptoms, heart rate adjustment, and quality of life were analyzed. Multivariate analysis was performed. Results. No operative mortality and conversion to open surgery were recorded. Mean operative time was 38 ± 5 minutes. Mean hospital stay was 1.1 ± 0.6 days. Eight patients (6%) had unilateral pneumothorax. Twenty-five cases (19%) were complicated by compensatory sweating. Winter and fall were identified as protective factors for compensatory sweating occurrence. Decreased heart rate was observed 1 year after surgery and permanently over the time. No recurrence during the follow-up period (31.5 months) was observed and 90% of patients showed improved quality of life. Conclusions. One-stage bilateral miniuniportal thoracoscopic sympathectomy is a valid and safe treatment for primary hyperhidrosis, achieving definitive and esthetic results, with excellent patients' satisfaction. Compensatory sweating may potentially occur in a season-dependent manner. PMID:24383050

    A computationally efficient speech enhancement pipeline in noisy environments based on a single-processor implementation is developed for utilization in bilateral cochlear implant systems. A two-channel joint objective function is defined and a closed form solution is obtained based on the weighted-Euclidean distortion measure. The computational efficiency and no need for synchronization aspects of this pipeline make it a suitable solution for real-time deployment. A speech quality measure is used to show its effectiveness in six different noisy environments as compared to a similar one-channel enhancement pipeline when using two separate processors or when using independent sequential processing.

    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.

    Introduction The videothoracoscopic approach is minimally invasive with benefits that include less postoperative pain and shorter hospital stay. It is also a safe procedure which can be performed on an outpatient basis. Aim To determine whether videothoracoscopic sympathicotomy can be performed safely in most patients as an outpatient procedure. Material and methods Between July 2005 and October 2015, a total of 92 patients underwent bilateral and single port thoracoscopic sympathicotomy in our department on an outpatient basis. The level of sympathicotomy was T2 in 2 (2.2%) patients, T2 to T3 in 31 (33%) patients, T2 to T4 in 46 (50%) patients and T3 to T4 in 12 (13%) patients. Demographic data, length of postoperative stay, substitution index (SI), admission rate (AR) and readmission rate (RR), complications and patient satisfaction were reviewed retrospectively. Results Two (2.2%) patients suffered from chest pain, while 4 (4.3%) patients complained about pain at the port site. Mean discharge time after surgery was 5.1 h (range: 4–6 h), mean duration of hospital stay was 0.15 days (0–3 days) postoperatively and the mean operation time was 43.6 min (15–130 min). In 8 (8.6%) patients, pneumothorax was detected on postoperative chest X-ray, while 5 (5.4%) patients required chest tube drainage. Mild or moderate compensatory sweating developed in 32 (34.7%) patients. No recurrence was observed, and the satisfaction rate was 96.7%. Substitution index and admission rate were 91.3% and 11% respectively, while RR was 0%. Conclusions Bilateral video-assisted thoracoscopic sympathicotomy can be performed safely in most patients as an outpatient procedure. PMID:27458488

    Bilateral malignant ovarian germ cell tumors (MOGCTs) are rare. Determination of the optimal treatment modalities is crucial, as these malignancies mainly affect girls and young women who may wish to preserve their fertility. In order to review the prevalence, clinical characteristics, treatment and outcome of bilateral MOGCTs, we performed a retrospective review of patients who were diagnosed with bilateral MOGCTs and underwent primary surgery at the Obstetrics and Gynecology Hospital of Fudan University (Shanghai, China) between January, 2001 and December, 2014. Of the 130 patients investigated, 8 were diagnosed with bilateral disease, most of whom were International Federation of Gynecology and Obstetrics stage I. There was no significant difference in overall and disease-free survival between patients with unilateral and those with bilateral disease. Cases with dysgerminoma, dysgerminoma coexisting with gonadoblastoma, yolk sac tumor and ovarian primary choriocarcinoma were included in this study. Fertility was spared in 2 patients (1 with dysgerminoma and 1 with ovarian primary choriocarcinoma). The patient with ovarian choriocarcinoma experienced relapse and was finally salvaged by radical surgery and adjuvant chemotherapy. According to our results and the published data, patients affected by bilateral MOGCTs have a satisfactory prognosis. The treatment modalities largely depend on the histological type of the tumor. Fertility-sparing surgery may be safe for patients affected by dysgerminoma, but should be considered with caution in patients with ovarian primary choriocarcinoma. PMID:27446585

    2011-01-01

    Background Simultaneous osteoarthritis (OA) of the ankle joint complicates primary total knee arthroplasty (TKA). In such cases, rehabilitation of TKA is limited by debilitating ankle pain, but varus or valgus ankle arthritis may even compromise placement of knee prosthetic components. Case presentation We present a patient with simultaneous bilateral valgus and patellofemoral OA of the knees and bilateral varus OA of the ankle joints that equally contributed to overall disability. This 63 years old, motivated and otherwise healthy patient was treated by simultaneous bilateral total knee and ankle arthroplasty (quadruple total joint arthroplasty, TJA) during the same anesthesia. Two years outcome showed excellent alignment and function of all four replaced joints. Postoperative time for rehabilitation, back to work (6th week) and hospital stay (12 days) of this special patient was markedly reduced compared to the usual course of separate TJA. Conclusions Simultaneous quadruple TJA in equally disabling OA of bilateral deformed knees and ankles resulted in a better functional outcome and faster recovery compared to the average reported results after TKA and TAA in literature. However, careful preoperative planning, extensive patient education, and two complete surgical teams were considered essential for successful performance. To the best of our knowledge this is the first case report in literature about quadruple major total joint arthroplasty implanted during the same anesthesia in the same patient. PMID:21995682

    OBJECTIVES Video-assisted thoracoscopic sympathectomy is currently the best treatment for palmar and axillary hyperhidrosis. It can be performed through either one or two stages of surgery. This study aimed to evaluate the operative and postoperative results of two-stage unilateral vs one-stage bilateral thoracoscopic sympathectomy. METHODS From November 1995 to February 2011, 270 patients with severe palmar and/or axillary hyperhidrosis were recruited for this study. One hundred and thirty patients received one-stage bilateral, single-port video-assisted thoracoscopic sympathectomy (one-stage group) and 140, two-stage unilateral, single-port video-assisted thoracoscopic sympathectomy, with a mean time interval of 4 months between the procedures (two-stage group). RESULTS The mean postoperative follow-up period was 12.5 (range: 1–24 months). After surgery, hands and axillae of all patients were dry and warm. Sixteen (12%) patients of the one-stage group and 15 (11%) of the two-stage group suffered from mild/moderate pain (P = 0.8482). The mean operative time was 38 ± 5 min in the one-stage group and 39 ± 8 min in the two-stage group (P = 0.199). Pneumothorax occurred in 8 (6%) patients of the one-stage group and in 11 (8%) of the two-stage group. Compensatory sweating occurred in 25 (19%) patients of the one-stage group and in 6 (4%) of the two-stage group (P = 0.0001). No patients developed Horner's syndrome. CONCLUSIONS Both two-stage unilateral and one-stage bilateral single-port video-assisted thoracoscopic sympathectomies are effective, safe and minimally invasive procedures. Two-stage unilateral sympathectomy can be performed with a lower occurrence of compensatory sweating, improving permanently the quality of life in patients with palmar and axillary hyperhidrosis.

    Study Design Cross-sectional, controlled laboratory study. Background Postural control following anterior cruciate ligament reconstruction (ACLR) primarily has been investigated during static single-leg balance tasks. Little is known about dynamic postural control deficits post-ACLR. Objectives To compare dynamic postural control (bilaterally) in individuals who have undergone ACLR and in healthy controls, and to evaluate the relationship between dynamic postural control and self-reported and objective function. Methods Ninety-seven participants (66 male; median age, 28 years) 12 months post-ACLR and 48 healthy controls (20 male; median age, 30 years) underwent balance assessment using a Nintendo Wii Balance Board during a single-leg squat. Center-of-pressure (CoP) path velocity, as well as CoP amplitude and standard deviation, in both mediolateral (ML) and anteroposterior (AP) directions were recorded. Self-reported function was assessed with the International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC), while hop for distance was used to evaluate functional status. Results Compared to healthy controls, the ACLR group had greater mean CoP path velocity (16% higher, P = .004), ML range (23%, P<.001), ML SD (28%, P<.001), AP range (14%, P = .009), and AP SD (15%, P = .013), indicating worse dynamic balance post-ACLR. Dynamic balance performance was similar between the ACLR limb and the uninjured contralateral limb. The AP SD was weakly associated with hop performance (β = -.2, P = .046); no balance measures were associated with IKDC score. Conclusion Individuals who have undergone ACLR demonstrate impaired dynamic balance bilaterally when performing a single-leg squat, which may have implications for physical function and future injury risk. Routine dynamic balance assessment may help identify patients who could benefit from targeted neuromuscular training programs to improve objective function and potentially lower reinjury risk.

    Herein the authors report the first case of prophylactic bilateral salpingo-ovariectomy (BSO) in single port access laparoscopy (SPAL) with use of diode laser in a patient with BRCA1 mutation. As fimbria could be considered the site of origin for many serous carcinomas in BRCA mutation carriers, many studies are carried out to evaluate the possibility of preventing ovarian carcinoma with BSO. SPAL is a development of endoscopic surgery which further reduces invasiveness of surgical procedures. Diode laser presents a recognized precision for tissue cutting and coagulation and its use could be highly advantageous in SPAL surgery and in particular in such situations avoiding fallopian tube histology distortion and consequently improve the prognosis of BRCA carriers.

    Since the development of video endoscopic surgery, the number of transthoracic endoscopic sympathectomy has been increasing. The use of double-lumen endobronchial tube or single-lumen endobronchial tube during anesthesia for these surgeries has been a controversial. 385 palmar hyperhidrosis patients divided into three groups: group I, under alterative one lung ventilation anesthesia with double-lumen endobronchial tube; group II, under alterative one lung ventilation anesthesia with single-lumen endobronchial tube; group III, under two lung ventilation anesthesia with single-lumen endobronchial tube were studied. All had received bilateral thoracoscopic sympathectomy. The age of patients ranged from 8 to 64 years old. There were 154 male and 231 female. The average anesthesia durations for group I, II and III were 38.56 +/- 10.28, 34.14 +/- 5.21, 31.83 +/- 3.34 min respectively. The variables considered in the study were: physique of the patients; duration of anesthesia; airway pressure changes; SaO2 changes during the operation and post-anesthesia complaints. We found that upon using double-lumen endobronchial tube, SaO2 levels was better maintained especially in the obese patients and the patients who had received a traditional surgical operation before.

    Introduction: Assessment of treatment outcomes in patients undergoing bilateral single-session retrograde intra-renal surgery (RIRS) for bilateral renal stones up to 1.5 cm. Materials and Methods: Retrospective analysis of 74 patients was done with bilateral renal calculi, who underwent bilateral single-session RIRS at our stone referral hospital from December 2011 to May 2014. The selection criteria for this intervention were patient's preference, failure of other treatments and stone up to 1.5 cm. Patients with creatinine more than 2, pyonephrosis sepsis, bilateral impacted pelviureteric junction calculi were excluded from study. All patients were evaluated with serum biochemistry, urinalysis, urine culture, plain radiography of kidney-ureter-bladder, intravenous urography, renal ultrasonography (USG) and/or computed tomography (CT). Follow-up evaluation included serum biochemistry and postoperative plain film and renal USG. The success rate was defined as patients who were stone-free or only had a residual fragment of less than 4 mm. CT was conducted only in patients with residual stones, which were present in seven patients. Results: A total of 74 patients (50 male, 24 female) with a mean age 39.2 ± 15.2 were included in the present study. The mean stone size was 11.7 ± 2.4 mm. The stone-free rates were 86.84% and 97.29% after the first and second procedures, respectively. In eight patients (10.8%), minor complications were observed, whereas no major complications were noted in the studied group. There was no significant difference in pre- and post-operative serum creatinine levels. Conclusion: In patients with bilateral renal stones up to 1.5 cm bilateral single-session RIRS with flexible ureteroscope can be safely performed with low complication rate. PMID:26834403

    Commercial spaceflight participants are typically older than traditional astronauts and often have medical conditions that make medical certification for flight difficult. This case report considers a 43-yr-old spaceflight participant who planned a short-duration Soyuz flight to the International Space Station (ISS). While he participated in many hazardous activities such as parachuting, hang gliding, scuba diving, Antarctic and jungle exploration, and deep sea submersible operations, he knew that several of his medical conditions precluded serving as a career astronaut. At the time of his initial spaceflight prescreen examination, he was known to have previous bilateral photorefractive keratectomy (PRK) for myopia and a cross-fused left ectopic kidney that would be disqualifying for a career astronaut. During the evaluation for the left single cross-fused ectopic kidney, a giant hepatic hemangioma was also discovered. In order to medically qualify for flight, the giant hepatic hemangioma was surgically removed. This case summary investigat*es the implications of a single cross-fused left ectopic kidney and the decision process and treatment implications for spaceflight medical certification in an individual with an asymptomatic giant hepatic hemangioma.

    We report cases of ectopic ureter accompanied by three types of ureteral duplication that had been diagnosed previously and treated for enuresis. Data from three female patients ranging in age from 1 to 10 years were evaluated. The ectopic ureter was observed on the left in one case, on the right in another and bilateral in the third case. Complete duplication was found in two cases, while the third had incomplete duplication. Ureteroneocystostomy was performed in one case and subtotal nephrectomy was carried out in the other two cases. Ureteroneocystostomy was performed for the ectopic ureter found in the opposite urinary system in one of the cases. Ectopic duplicated ureter should be considered in treatment-resistant enuresis and urinary tract infections and after a careful physical examination, imaging as well as function tests should be performed.

    The determination of physiologic lower limb functional imbalance among healthy teenagers is important to follow the rehabilitation progress and return to normal activity of injured subjects. We investigated the differences in vertical jump capacity between both legs in a group of healthy boys and girls, considering the performances in the dominant vs. non-dominant, and in the most vs. least efficient leg. Strength and power performances were compared in 117 boys and 106 girls aged 10-16 years during a single-leg vertical countermovement jump (SLVCJ) test. When leg dominance was defined subjectively by the participant, no difference was noted between the 2 legs. Statistically significant differences were recorded between the most and less efficient leg in strength and power performances for both genders. Girls had significantly greater peak strength than did age-matched boys, but boys showed significant increases in maximal power outputs compared with that shown by age-matched girls. When the results were analyzed according to the percentage of participants falling within certain bands of limb asymmetry, approximately 20-30% showed a difference of >15% between the 2 limbs without any relation to gender. Subjective expression of leg dominance cannot be used as a predictor of SLVCJ performance. Differences of <15% in SLVCJ performance between both legs should be considered as the physiological norm in this age group. A greater appreciation of the potential diagnostic value of the SLVCJ test may be obtained if the results are interpreted in terms of the percentage of subjects falling within certain bands of limb asymmetry. Gender-based differences in the SLVCJ test vary and depend upon whether the results are interpreted in terms of strength or power output.

    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. PMID:21197082

    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.

    The authors studied 8 patients (4 males and 4 females) with Cushing's syndrome due to ectopic ACTH secretion. Chronological age ranged from 15 to 45 years and duration of the disease ranged from 3 to 48 months. All patients presented typical signs of Cushing's syndrome, blood hypertension, and four of them had hyperpigmentation of the skin. Five patients had fasting hyperglycemia and all patients but one had serum hypokalemia (serum K = 2.2 to 3.9mEq/l). The circadian rhythm of cortisol was absent in all patients and basal cortisol levels were elevated in all patients but one. Basal ACTH levels evaluated in 7 patients were elevated in 6 (29 to 1050 pg/ml-MRC). One patient presented normal depression of urinary 17-OH after two days of dexamethasone and normal increase of urinary 17-OH and serum 11-dexycortisol after methyrapone. Four patients had carcinoid tumor (3 thymic and 1 bronchial), two had pancreatic islets cell tumors, one had bilateral pheochromocytoma and medular carcinoma of the thyroid, and one had oat cell carcinoma of the lung and medular carcinoma of the thyroid. Thoracic X-rays identified the ectopic ACTH secretion tumor in four cases, all confirmed by CT scan. Abdominal CT showed a difuse enlargement of the adrenals in seven cases and bilateral nodules in one case (pheochromocytomas). Six patients died within 3 years of the diagnosis. The authors concluded that clinical and hormonal findings could mislead the findings of ACTH ectopic secretion and Cushing's disease, and suggest that thoracic X-rays and CT scans of the skull, thorax, and abdome should be done in all cases of Cushing's syndrome.

    Purpose To evaluate the performance of a model-based optimisation process for volumetric modulated arc therapy, VMAT, applied to whole breast irradiation. Methods and Materials A set of 150 VMAT dose plans with simultaneous integrated boost were selected to train a model for the prediction of dose-volume constraints. The dosimetric validation was done on different groups of patients from three institutes for single (50 cases) and bilateral breast (20 cases). Results Quantitative improvements were observed between the model-based and the reference plans, particularly for heart dose. Of 460 analysed dose-volume objectives, 13% of the clinical plans failed to meet the constraints while the respective model-based plans succeeded. Only in 5 cases did the reference plans pass while the respective model-based failed the criteria. For the bilateral breast analysis, the model-based plans resulted in superior or equivalent dose distributions to the reference plans in 96% of the cases. Conclusions Plans optimised using a knowledge-based model to determine the dose-volume constraints showed dosimetric improvements when compared to earlier approved clinical plans. The model was applicable to patients from different centres for both single and bilateral breast irradiation. The data suggests that the dose-volume constraint optimisation can be effectively automated with the new engine and could encourage its application to clinical practice. PMID:26691687

    Summary Background If a kidney does not ascend as it should in normal fetal development, it remains in the pelvic area and is called a pelvic kidney. Often a person with a pelvic kidney will go through his/her whole life unaware of this condition, unless it is discovered during neonatal kidney ultrasound screening or if complications arise later in life due to this or a completely different reason and the condition is noted during investigations. Generally, this is not a harmful condition but it can lead to complications like in our case. With appropriate testing and treatment, if needed, an ectopic kidney should cause no serious long-term health complications and all that may be required for the patient is reassurance with advice to follow up at regular intervals. Case Report A 28-year-old male presented with recurrent pain in his lower left abdomen for one month and an episode of hematuria 3 days earlier accompanied by an attack of acute pain lasting for 3–4 hours. He gave a history of passing 2 small (about 5 mm each) calculi in his urine after the occurrence of hematuria, following which pain decreased in intensity. No history of fever was present. Conclusions Although a simple ectopic kidney seldom causes symptoms, the association of malrotation of the renal pelvis with calculus increases the risk of hematuria and/or hydronephrosis, presenting with colicky pain as in the present case. The clinician should be aware of these in such a case. If asymptomatic, no treatment is required. However, the patient should be advised to have follow-up ultrasounds at regular intervals to detect complications like calculus, hydronephrosis, etc. With appropriate testing and treatment, if required, an ectopic kidney should not cause serious long-term health complications.

Although logistically challenging, this case demonstrates the feasibility and safety of the recovery of multiple thoracic and abdominal organs with multiple vascular composite allotransplants and tissues. Our experience of 8 additional successful multiple vascular composite allotransplants, thoracic, and abdominal organ recoveries suggests that such procedures are readily accomplishable from the same deceased donor.

    The leading symptoms of bilateral vestibulopathy (BVP) are postural imbalance and unsteadiness of gait that worsens in darkness and on uneven ground. There are typically no symptoms while sitting or lying under static conditions. A minority of patients also have movement-induced oscillopsia, in particular while walking. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR). This deficit is diagnosed for the high-frequency range of the angular VOR by a bilaterally pathologic bedside head impulse test (HIT) and for the low-frequency range by a bilaterally reduced or absent caloric response. If the results of the bedside HIT are unclear, angular VOR function should be quantified by a video-oculography system (vHIT). An additional test supporting the diagnosis is dynamic visual acuity. Cervical and ocular vestibular-evoked myogenic potentials (c/oVEMP) may also be reduced or absent, indicating impaired otolith function. There are different subtypes of BVP depending on the affected anatomic structure and frequency range of the VOR deficit: impaired canal function in the low- and/or high-frequency VOR range only and/or otolith function only; the latter is very rare. The etiology of BVP remains unclear in more than 50% of patients: in these cases neurodegeneration is assumed. Frequent known causes are ototoxicity mainly due to gentamicin, bilateral Menière's disease, autoimmune diseases, meningitis and bilateral vestibular schwannoma, as well as an association with cerebellar degeneration (cerebellar ataxia, neuropathy, vestibular areflexia syndrome=CANVAS). In general, in the long term there is no improvement of vestibular function. There are four treatment options: first, detailed patient counseling to explain the cause, etiology, and consequences, as well as the course of the disease; second, daily vestibular exercises and balance training; third, if possible, treatment of the underlying cause, as in bilateral

    This study examined how force tremor and muscle activity are altered between limbs when a visual target is removed for one limb during bilateral index finger abduction. Isometric index finger abduction force was examined in healthy adults (23 ± 4 years) when both index fingers abducted simultaneously. Abduction forces ranged from 5 to 20% maximum voluntary contraction, and these target forces were displayed on a PC monitor in front of the subject. Force tremor and first dorsal interosseous (FDI) activity were first collected while subjects viewed visual targets for both index fingers and then when the visual target was removed for the non-dominant index finger. Subjects successfully matched the force amplitudes generated for both limbs regardless of visual condition. When the visual target was removed for one limb, force tremor increased in this limb (p < 0.01). Different power spectral profiles were evident for each FDI EMG when targets were available for both limbs (p < 0.05); however, when one target was removed, the pattern of FDI EMG for the limb without a visual target closely reflected FDI EMG for the limb which had the visual target. The CNS actively modulates muscle activity in each limb to perform visually guided isometric contractions. Given that the goal was to match force output with both limbs, the requirements of the task must be established from the limb that had a visual target, and a copy of those motor commands appears to have been sent to the FDI of the limb without a visual target.

    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.

    Bilateral salpingo-oophorectomy (BSO) in carriers of BRCA1 and BRCA2 mutations is widely recommended as part of a risk-reduction strategy for ovarian or breast cancer due to an underlying genetic predisposition. BSO is also performed as a therapeutic intervention for patients with hormone-positive premenopausal breast cancer. BSO may be performed via a minimally invasive approach with the use of three to four 5 mm and/or 12 mm ports inserted through a skin incision. To further reduce the morbidity associated with the placement of multiple port sites and to improve cosmetic outcomes, single-port laparoscopy has been developed with a single access point from the umbilicus. The purpose of this study was to evaluate the surgical outcomes associated with reducing the risks of salpingo-oophorectomy performed in a single port, while comparing multiport laparoscopy in women with a high risk for ovarian cancer. Single-port laparoscopy–BSO is feasible and safe, with favorable surgical and cosmetic outcomes when compared to conventional laparoscopy. PMID:26170692

    Persistent Mullerian Duct Syndrome (PMDS) is a form of internal male pseudohermaphroditism, where there is normal development of male secondary sexual characters, along with the presence of bilateral fallopian tubes and uterus. Majority of these cases go undetected and some cases are accidentally diagnosed while investigating for other problems. Cross fused renal ectopia is a condition where one kidney lies in the opposite side, fused to the other kidney. We present an extremely rare case of a phenotypical male presenting with mass per abdomen and bilateral cryptorchidism, turned out to have uterus with bilateral fallopian tubes, ectopic cross fused right kidney and Embryonal cell carcinoma of left undescended testis.

    In addition to the subcutaneous and the visceral fat tissue, lipids can also be stored in non-adipose tissue such as in hepatocytes (intrahepatocellular lipids; IHCL), skeletal (intramyocellular lipids; IMCL) or cardiac muscle cells (intracardiomyocellular lipids; ICCL). Ectopic lipids are flexible fuel stores that can be depleted by physical exercise and repleted by diet. They are related to obesity and insulin resistance. Quantification of IMCL was initially performed invasively, using muscle biopsies with biochemical and/or histological analysis. 1H-magnetic resonance spectroscopy (1H-MRS) is now a validated method that allows for not only quantifying IMCL non-invasively and repeatedly, but also assessing IHCL and ICCL. This review summarizes the current available knowledge on the flexibility of ectopic lipids. The available evidence suggests a complex interplay between quantitative and qualitative diet, fat availability (fat mass), insulin action, and physical exercise, all important factors that influence the flexibility of ectopic lipids. Furthermore, the time frame of the intervention on these parameters (short-term vs. long-term) appears to be critical. Consequently, standardization of physical activity and diet are critical when assessing ectopic lipids in predefined clinical situations. PMID:27649157

    Neurons in the pontomedullary reticular formation (PMRF) give rise to the reticulospinal tract. The motor output of the PMRF was investigated using stimulus-triggered averaging of electromyography (EMG) and force recordings in two monkeys (M. fascicularis). EMG was recorded from 12 pairs of upper limb muscles, and forces were detected using two isometric force-sensitive handles. Of 150 stimulation sites, 105 (70.0%) produced significant force responses, and 139 (92.5%) produced significant EMG responses. Based on the average flexor EMG onset latency of 8.3 ms and average force onset latency of 15.9 ms poststimulation, an electromechanical delay of ∼7.6 ms was calculated. The magnitude of force responses (∼10 mN) was correlated with the average change in EMG activity (P < 0.001). A multivariate linear regression analysis was used to estimate the contribution of each muscle to force generation, with flexors and extensors exhibiting antagonistic effects. A predominant force output pattern of ipsilateral flexion and contralateral extension was observed in response to PMRF stimulation, with 65.3% of significant ipsilateral force responses directed medially and posteriorly (P < 0.001) and 78.6% of contralateral responses directed laterally and anteriorly (P < 0.001). This novel approach permits direct measurement of force outputs evoked by central nervous system microstimulation. Despite the small magnitude of poststimulus EMG effects, low-intensity single-pulse microstimulation of the PMRF evoked detectable forces. The forces, showing the combined effect of all muscle activity in the arms, are consistent with reciprocal pattern of force outputs from the PMRF detectable with stimulus-triggered averaging of EMG.

    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.

    Our main objective is to report the feasibility of performing simultaneous robotic-assisted laparoscopic (RAL) heminephrectomy with contralateral ureteroureterostomy in children with bilateral duplicated systems. Three female children with bilateral congenital renal/ureteral anomalies underwent concurrent RAL simultaneous unilateral partial nephrectomy with ureterectomy and contralateral ureteroureterostomy with redundant ureterectomy using a four/five-port approach. Mean age at repair was 32.9 months (range 7-46 months) and mean weight was 13.7 kg (range 10.4-13.6 kg). The RAL heminephroureterectomy and contralateral ureteroureterostomy were performed via a four-port approach (five ports in one patient), and the patients were repositioned and draped when moving to the other side. Mean operative time was 446 min (range 356-503 min). Mean estimated blood loss was 23.3 cc (range 10-50 cc).

No significant intraoperative or postoperative complications occurred for any of the three patients. Two children had no hydronephrosis on postoperative imaging in follow-up, and one child had a small stable, residual pararenal fluid collection on the side of heminephrectomy. Two patients underwent postoperative ureteral stent removal under general anesthesia.

    Our main objective is to report the feasibility of performing simultaneous robotic-assisted laparoscopic (RAL) heminephrectomy with contralateral ureteroureterostomy in children with bilateral duplicated systems. Three female children with bilateral congenital renal/ureteral anomalies underwent concurrent RAL simultaneous unilateral partial nephrectomy with ureterectomy and contralateral ureteroureterostomy with redundant ureterectomy using a four/five-port approach. Mean age at repair was 32.9 months (range 7-46 months) and mean weight was 13.7 kg (range 10.4-13.6 kg). The RAL heminephroureterectomy and contralateral ureteroureterostomy were performed via a four-port approach (five ports in one patient), and the patients were repositioned and draped when moving to the other side. Mean operative time was 446 min (range 356-503 min). Mean estimated blood loss was 23.3 cc (range 10-50 cc). Postoperative length of stay for two patients was 2 days and 1 day for one patient (mean = 1.7 days). Mean length of follow-up was 18.3 months (range 7-36 months). No significant intraoperative or postoperative complications occurred for any of the three patients. Two children had no hydronephrosis on postoperative imaging in follow-up, and one child had a small stable, residual pararenal fluid collection on the side of heminephrectomy.

    The objective of this prospective parallel randomized single-blind study was to assess that a cycle of mud-bath therapy (MBT) provides any benefits over usual treatment in patients with bilateral knee osteoarthritis (OA). Patients with symptomatic primary bilateral knee OA, according to ACR criteria, were included in the study and randomized to one of two groups: one group received a cycle of MBT at spa center of Chianciano Terme (Italy) in addition to the usual treatment, and one group continued their regular care routine alone. Clinical assessments were performed 7 days before enrollment (screening visit), at the time of enrollment (basal time), after 2 weeks, and after 3, 6, 9, and 12 months after the beginning of the study. All assessments were conducted by two researchers blinded to treatment allocation. The primary efficacy outcomes were the global pain score evaluated by Visual Analog Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) subscore for physical function (W-TPFS). Of the 235 patients screened, 103 met the inclusion criteria: 53 patients were included in the MBT group and 50 in the control group. In the group of patients treated with MBT, we observed a statistically significant ( p < 0.001) reduction of VAS and W-TPFS score at the end of the treatment; this improvement was significant ( p < 0.05) also at 3 months of follow-up. The control group did not show significant differences between baseline time and all other times. The differences between one group were significant for both primary parameters already from the 15th day and persisted up to the 9th month. This beneficial effect was confirmed by the significant reduction of symptomatic drug consumption. Tolerability of MBT seemed to be good, with light and transitory side effects. Our results confirm that a cycle of MBT added to usual treatment provides a beneficial effect on the painful symptoms and functional capacities in patients with knee OA that

  1. Bilateral Advantages in Subitizing With Visual Masking.

    Performance on a range of visual-processing tasks has been shown to improve when information is split bilaterally across the left and right visual hemifields rather than being restricted to a single visual hemifield. However, a recent study by Delvenne et al. found no such bilateral advantage for subitizing, which is our ability to rapidly and accurately enumerate small quantities of objects. This finding is particularly surprising, as it contradicts the prediction of FINgers of INSTantiation theory that subitizing should benefit from bilateral presentation. Our study investigated the issue by determining if there are any circumstances where a bilateral advantage for subitization occurs. Contrary to Delvenne et al., we found that subitizing could show bilateral advantages, but only when the display was backward-masked. We discuss these findings in relation to how the rate of encoding and the time available for this encoding may affect bilateral advantages in subitizing. A general model is proposed under which bilateral advantages could be explained.

  2. Misdiagnosis of bilateral tubal pregnancy: a case report

    PubMed Central

    2014-01-01

    Introduction The incidence of bilateral tubal pregnancy is rising due to the increase of pelvic inflammatory disease and assisted reproductive techniques. Because the clinical manifestations of bilateral tubal pregnancy are not specific, we often ignore inspection of the other fallopian tube when focusing on the lesions, which may cause misdiagnosis. Case presentation A 33-year-old Chinese woman presented with vaginal bleeding after menopause and with an abnormality found by transvaginal ultrasound scan for which she underwent laparoscopy and salpingectomy. Unfortunately, she had to undergo a repetitive laparoscopic salpingotomy for the other tubal pregnancy due to misdiagnosis of her bilateral tubal pregnancy. Conclusions The incidence of unusual presentations of ectopic pregnancies has risen. Surgeons should always keep in mind the possibility of bilateral tubal pregnancy. An attentive examination of the pelvis, especially the two fallopian tubes, is necessary to avoid missing bilateral tubal pregnancy. PMID:25312677

    Cushing's syndrome (CS) is defined as a constellation of clinical signs and symptoms occurring due to hypercortisolism. Cortisol excess may be endogenous or exogenous. The most common cause of CS is glucocorticoid therapy with supraphysiological (higher than in the case of substitution) doses used in various diseases (e.g. autoimmune). One possible CS cause is ectopic (extra-pituitary) ACTH secretion (EAS) by benign or malignant tumours. Since its first description in 1963, EAS aetiology has changed, i.e. as well as small cell lung cancer (SCLC), higher incidence in other malignancies has been reported. Ectopic ACTH secretion symptoms are usually similar to hypercortisolism symptoms due to other causes. A clinical suspicion of CS requires laboratory investigations. There is no single and specific laboratory test for making a CS diagnosis, and therefore multiple dynamic tests should be ordered. A combination of multiple laboratory noninvasive and invasive tests gives 100% sensitivity and 98% specificity for EAS diagnosis. If the EAS is caused by localised malignancy, surgery is the optimal treatment choice. Radical tumour excision may be performed in 40% of patients, and 80% of them are cured of the disease. The authors present an interesting clinical case of EAS, which is always a huge diagnostic challenge for clinicians. (Endokrynol Pol 2016; 67 (4): 458-464). PMID:27387249

    2016-01-01

    Medullary thyroid carcinoma (MTC) has been described as a source of ectopic ACTH secretion in patients with Cushing's syndrome. This is an infrequent association, occurring in less than 1% of MTC cases. Among these, it is even more unusual for an initial diagnosis of hypercortisolism to lead to the discovery of underlying MTC. Here we present a case of a patient with weakness, diarrhea, and hypokalemia who was found first to have Cushing's syndrome and later diagnosed with metastatic MTC. The patient was treated initially with oral agents to control his hypercortisolism, then with an etomidate infusion after experiencing intestinal perforation. He also received vandetanib therapy targeting his underlying malignancy, as this has been shown to reverse clinical signs of Cushing's syndrome in patients with MTC and subsequent ectopic ACTH secretion. Bilateral adrenalectomy was ultimately required. Medullary thyroid carcinoma should be considered in patients presenting with Cushing's syndrome due to ectopic ACTH secretion, and a multimodality treatment approach is often required. PMID:27141514

    Ectopic or tertiary lymphoid tissues develop at sites of inflammation or infection in peripheral, non-lymphoid organs. These tissues are architecturally similar to conventional secondary lymphoid organs, with separated B and T cell areas, specialized populations of dendritic cells, well-differentiated stromal cells and high endothelial venules. Ectopic lymphoid tissues are often associated with the local pathology that results from chronic infection or chronic inflammation. However, there are also examples in which ectopic lymphoid tissues appear to contribute to local protective immune responses. Here we review how ectopic lymphoid structures develop and function in the context of local immunity and pathology. PMID:18243731

    Extrauterine formation of decidua of stromal cells has been well described, particularly in the cervix and ovary. Sporadic reports have documented decidua formation of peritoneal surfaces and lymph nodes as well as ovarian ectopic decidua in pregnant patients. The apparent hormonal mechanism of this phenomenon suggests a relationship to endometriosis. Between 1983 and 1986, tissue from 10 pregnant patients (acquired from nine at cesarean section and from one at appendectomy) demonstrated submesothelial decidua formation in the form of microscopic nodules and diffuse cell arrangements in an edematous stroma. Some cases showed mild chronic inflammation. An intracytoplasmic lipofusin-type pigment was observed in one case. Four cases had diffuse omental involvement: two with small amounts of free peritoneal blood and two with peritoneal adhesions. Three cases were associated with paratubal cysts: two of these occurred in the uterine and appendiceal serosa, respectively, and one case showed involvement of a retroperitoneal lymph node associated with a pheochromocytoma. No specific gross observations were noted at surgery. There was no prior or subsequent evidence of endometriosis. A review of 958 elective tubal ligations performed between 1983 and 1985 demonstrated 52 examples (5.5%) of serosal decidua formation. Ectopic stromal decidua formation in pregnancy is: (a) a physiologic phenomenon related to the possible specialized sensitivity of the superficial coelomic stroma to progesterone; and (b) diffusely distributed in the peritoneum although it is a clinicopathologic process distinct from endometriosis.

    Anomalous kidneys are mostly asymptomatic and are often found incidentally during physical or radiological investigations for urological or other medical complaints. The associated genital anomalies ranges from 15% to 45%. Females are associated with bicornuate or unicornuate uterus, rudimentary or absent uterus while males have undescended testes, duplication of the urethra, and hypospadias. A 21 year old married female presented with on and off lower abdomen pain for the past one year with history of primary amenorrhea. On examination an ill defined tender lump palpated in the lower abdomen. USG showed left ectopic pelvic kidney with gross hydronephrosis. The computed tomography confirmed hydronephrotic left ectopic pelvic kidney in front of the sacrum with anteriorly directed renal pelvis with ureter located posteriorly. There was delayed excretion from the ectopic kidney but right kidney was in normal position and function. The diethylene triamine pentaacetic acid (DTPA) scan showed 33% function of the ectopic kidney. On diagnostic laparoscopy, the uterus was small hypoplastic with bilateral ovaries appearing normal. The patient was taken for open pyeloplasty where the ureter was transected below PUJ but for a dependent drainage, the middle calyx as was the most dependent calyx as seen on the CT-scan. So a middle calyx ureterocalicostomy was performed calyx with excellent outcome. The ectopic kidney always remains a challenge because of complex neurovascular anatomy, presence of viscera and associated UPJO, but for a dependent drainage, middle calyx ureterocalicostomy is a feasible option with excellent outcome as was in our case.

    Ectopic or accessory adrenal tissues are usually found in the upper abdomen or along the path of descent of the gonads. The occurrence of supradiaphragmatic adrenal tissue is extremely rare. We report a case of ectopic adrenal tissue composed of both cortical and medullary cells in a 99-year-old woman. The lesion was found incidentally in the paratracheal region at autopsy. We performed in situ hybridization and immunohistochemistry to confirm that the ectopic adrenal tissue possessed the same steroidogenesis as a normal adrenal gland. The ectopic adrenal tissue was encapsulated by fibrous tissue and composed of cells expressing all steroidogenic enzyme mRNAs. The centrally located cells showed immunoreactivities for tyrosine hydroxylase (TH), dopamine beta hydroxylase (DBH), and phenylethanolamine-N-methyltransferase (PNMT). Expression of ACTH receptor (ACTHR) was also evident. These findings indicated that this ectopic adrenal tissue had the capability for steroid and catecholamine biosynthesis under the control of ACTH, and that it might function adequately even under a condition of bilateral adrenal insufficiency.

    Ectopic thyroid tissue is an uncommon congenital aberration. It is extremely rare to have three ectopic foci at three different sites. The thyroid scan has been used successfully to diagnose ectopic thyroid tissue. We report a case of ectopic thyroid tissue at base of tongue, another at the level of hyoid and third one as aberrant tissue at suprahyoid location in a 16 year old female who presented with swelling in front of neck. This patient was clinically diagnosed as thyroglossal cyst and was being planned for surgery. Preoperative thyroid scan helped in establishing diagnosis of ectopic thyroid which was the only functioning thyroid tissue. Thus, it prevented unnecessary surgery. Therefore it is suggested that thyroid scan and USG/CT scan must be done as routine work up in neck swellings pre operatively to avoid unnecessary surgeries.

    If one accepts a version of absolutism that excludes the intentional killing of any innocent human person from conception to natural death, ectopic pregnancy poses vexing difficulties. Given that the embryonic life almost certainly will die anyway, how can one retain one's moral principle and yet adequately respond to a situation that gravely threatens the life of the mother and her future fertility? The four options of treatment most often discussed in the literature are non-intervention, salpingectomy (removal of tube with embryo), salpingostomy (removal of embryo alone), and use of methotrexate (MXT). In this essay, I review these four options and introduce a fifth (the milking technique). In order to assess these options in terms of the absolutism mentioned, it will also be necessary to discuss various accounts of the intention/foresight distinction. I conclude that salpingectomy, salpingostomy, and the milking technique are compatible with absolutist presuppositions, but not the use of methotrexate.

    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.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. PMID:27352844

    The incidence of hydatidiform moles is 1 per 1,000 pregnancies. Ectopic pregnancy occurs in 20 per 1,000 pregnancies. Thus, the incidence of the ectopic molar gestation is very rare. We report a case of tubal molar pregnancy diagnosed at the systematic histology exam of an ectopic pregnancy. We report the case of 32 years old nulliparus women who presented a vaginal bleeding, lower abdominal pain and 6 weeks amenorrhea corresponding to the last menstrual period. At the clinical examination, the arterial pressure was 100/60 mmHG. The gynecological examination was difficult because of lower abdominal pain. Serum gonadotropin activity was 3454 ui/l. Pelvic ultrasound revealed an irregular echogenic mass in the left adnexa. Diagnostic laparoscopy revealed a left-sided unruptured ampullary ectopic pregnancy. A left laparoscopic salpingectomy was performed. The systematic histologic test identified an ectopic partial molar pregnancy, which was confirmed by DNA ploidy image analysis. The patient was followed with weekly quantitative B-hCG titers until three successive B-hCG levels were negative. It is pertinent that clinicians take routine histological examination of tubal specimens in ectopic pregnancy very seriously in order to diagnose cases of ectopic molar gestations early and mount appropriate post treatment surveillance.

    An ectopic osteogenesis experiment aboard the Cosmos-936 biosatellite is described. Decalcified, lyophilized femur and tibia were implanted under the fascia or in the anterior wall of the abdomen in rats. Bone formation before and after the tests is described and illustrated. The extent of formation of ectopic bone in weightlessness did not differ significantly from that in the ground controls, but the bone marrow of the ectopic bone of the flight rats consisted exclusively of fat cells. The deficit of support-muscle loading was considered to cause the disturbance in skeletal bone tissue development.

  2. Case report: nocardia infection associated with ectopic cushings

    2014-01-01

    Background Cushing’s syndrome results from exposure to excess glucocorticoids. Ectopic Cushings is endogenous ACTH dependant form of Cushing’s associated with markedly raised ACTH and cortisol levels. This leads to an impaired immune response, setting the stage for occurrence of opportunistic infections. Nocardiosis is a gram positive bacterial infection caused by aerobic actinomycetes in genus Nocardia. We report a series of patients diagnosed with ectopic Cushings, having pneumonia with Nocardia spp. In one of these cases, the manifestations of Cushing’s disappeared with treatment for Nocardia. Case presentation Two middle aged men of Asian descent presented to the Endocrine clinic: the first with history of exertional shortness of breath, and weight loss for 1 year, the other with facial swelling, disturbed sleep and lethargy for a month. The third case was a young Asian male who presented with progressive weakness & weight loss for 2 months. All three patients had uncontrolled hypertension, high blood sugars & were hypokalemic (K: 2.52, 2.9, 1.5 mmol/l); 24 hour urine cortisol was elevated at 2000, 27216 and 9088 (32-243 ug/24 hours); ACTH 68.5, 159, 255 [0–48 pg/ml), respectively. Their MRI pituitary was normal, inferior petrosal sinus sampling revealed no central peripheral gradient. CT chest of these subjects demonstrated cavitatory lung lesions; microscopic analysis of respiratory samples was suggestive of infection with Nocardia spp. Histopathology of bronchoscopic-guided biopsy revealed no malignancy. Antihypertensives, insulin, potassium replacement, ketoconazole & trimethoprim-sulphamethoxazole (TS) were initiated. The patients’ symptomatology improved & cavitatory lesions resolved with treatment. The primary source for the ectopic cushings remained unknown. The first case required bilateral adrenalectomy. The second case followed a progressively downhill course leading to death. In the third case, we were able to completely taper off

    Cushing's syndrome due to ectopic adrenocorticotrophic hormone (ACTH) secretion is infrequent, the most frequent cause being bronchial carcinoid; nevertheless, in a considerable proportion of cases (up to 16%), the origin of ACTH secretion is not found. Treatment of Cushing's syndrome due to ectopic ACTH secretion is surgical resection of the tumor. However, surgical excision is not always feasible, either because the tumor has not been located, or because it is unresectable; in these cases the question is when to carry out a bilateral adrenalectomy. We present a case of ACTH-dependent hypercortisolism, in which the ectopic origin of ACTH secretion was established from the results of complementary tests (suppression tests, petrosal sinus sampling, imaging); nevertheless, none of the imaging tests was able to identify the secreting tumor. Consequently, after a reasonable interval, a bilateral adrenalectomy was performed, with good clinical results.

    OBJECTIVE: To assess the incidence of ectopic pregnancy (EP) in hospitals in Conakry, the capital of Guinea, West Africa. Data on EP incidence in developing countries are rare and often out of date, particularly in Africa. METHODS: A retrospective study was carried out, examining all cases of EP registered in the medical files of two referral maternity units at the Donka and Ignace Deen university hospitals between 1995 and 1999. FINDINGS: The EP incidence at the two maternity units increased from 0.41% to 1.5% of annual deliveries over this period. Haemoperitoneum was observed in most women, with tubal rupture in 93%; only 6 women received conservative treatment. CONCLUSION: The results suggest that the hospital-based incidence of EP per delivery has increased over the last decade in this West African capital, and that health professionals and public health officials in developing countries, especially those in Africa, should consider EP as a major obstetric problem for maternal morbidity.

    Introduction: Unilateral anterior shoulder dislocation is one of the most common problems encountered in orthopedic practice. However, simultaneous bilateral anterior dislocation of the shoulders is quite rare. Case Presentation: We report a case of a 75-year-old woman presented with simultaneous bilateral anterior shoulder dislocation following a trauma, complicated with a traction injury to the posterior cord of the brachial plexus. Conclusions: Bilateral anterior shoulder dislocation is very rare. The excessive traction force during closed reduction may lead to nerve palsy. Clear documentation of neurovascular status and adequate imaging before and after a reduction should be performed. PMID:25685749

    The bilateral operculum syndrome, is a unique developmental syndrome. It is characterized by spastic paralysis of the muscles of the face, pharynx, and of mastication, as well as by epilepsy and mental retardation. Imaging studies show bilateral, structural abnormalities in the frontal, perisylvian region consistent with polymicrogyria. These children are usually diagnosed as suffering from cerebral palsy, but in the bilateral operculum syndrome, intelligence is relatively preserved despite the severe motor involvement. Misdiagnosis may lead to improper estimation of rehabilitation potential preventing appropriate therapy, especially in the field of alternative communication. We present a 3-year-old boy, apparently the first case of this syndrome to be described in Israel. PMID:8940497

    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.

    Ectopic pregnancy is the gynaecological emergency par excellence and remains the leading cause of pregnancy-related first trimester deaths in the UK. Its prevalence continues to rise because of increases in the incidence of the risk factors predisposing to ectopic pregnancy. Classically, the diagnosis is based on a history of pelvic pain associated with amenorrhoea, a positive pregnancy test with or without slight vaginal bleeding. While the immediate differential diagnosis includes threatened or inevitable miscarriage, the likelihood of ectopic pregnancy is increased if transvaginal sonography (TVS) reveals an empty uterine cavity, and is confirmed if an adnexal mass with or without an embryo is seen. However, the diagnosis is often not that simple, especially when the patient presents early, has minimal pain, is haemodynamically stable, and TVS shows an empty uterus but no obvious adnexal mass. This could then be an early intrauterine pregnancy, or could indeed be an ectopic-a diagnosis of pregnancy of unknown location is made while additional investigations are made. The latter usually include serial measurements of serum beta human chorionic gonadotrophin (beta-hCG) and repeat TVS. Changes in beta-hCG levels in normal, failing and ectopic pregnancy are now reasonably well characterised, and at early stages of presentation where the risk of rupture of an ectopic are minimal, the patient can often be managed as an outpatient while the diagnosis is pursued. In the patient who presents with pain and haemodynamic instability, the diagnosis is often obvious, and the management is immediate laparotomy. However, in modern gynaecological practice in the developed world the vast majority of ectopic pregnancies present early, and the general consensus is that laparoscopic management offers both economic and aesthetic advantages, and should be used whenever possible. Salpingectomy (excision of the fallopian tube containing the ectopic) is performed if the contra

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present. PMID:22247765

    The purpose of this review is to examine the current state of knowledge regarding the treatment of non-tubal ectopic pregnancies. This review looks at the management of cervical, caesarean scar, ovarian, interstitial, cornual and abdominal pregnancies. Traditionally these pregnancies have been diagnosed late and managed by open surgery. Earlier diagnosis has led to the use of minimal access techniques, medical and conservative management for all types of non-tubal pregnancies. Increased awareness and the experience of specialised centres have led to an improved understanding of the best way to manage non-tubal ectopic pregnancies and the development of new techniques.

We report a 53-year-old man with hypertension, diabetes, and symptoms of hypokalemia. Computer tomography (CT) revealed two retroperitoneal masses and bilateral adrenal hyperplasia. Together with the laboratory examinations, ectopic CS caused by multiple paragangliomas was highly suspected. The patient underwent resections of retroperitoneal tumours, left kidney, and left adrenal; postoperative histopathology confirmed two paragangliomas that were both positively stained for adrenocorticotropic hormone (ACTH). He got clinical and biochemical recoveries without any recurrent evidence at the nine-month followup.

    The deleterious effect of chronic or incessant supraventricular tachycardia on ventricular function is well-known and it has been demonstrated than can ultimately lead to dilated cardiomyopathy if unrecognized. Any variety of supraventricular tachycardia with chronic evolution may lead to left ventricular dysfunction, ectopic atrial tachycardia because of its persistent nature, often incessant and poorly responsive to antiarrhythmic drugs is a frequent cause of reversible congestive heart failure in patients without other demonstrable organic heart disease. Five patients (aged 14 to 52 years) were referred with symptoms of heart failure, NYHA functional class II (one patient), class III (one patient) and class IV (3 patients) associated with an incessant ectopic atrial tachycardia. Four patients underwent radiofrequency catheter ablation of the ectopic focus and one patient was treated with amiodarone. All patients were successfully treated and the echocardiographic assessment of left ventricular function indicated regression of the cardiomyopathy picture with recovery of systolic function, (mean left ventricular ejection fraction 39.2 +/- 6.1% before vs mean 62.4 +/- 4.8% after (p < 0.01). The clinical and echocardiographic picture of cardiomyopathy induced by incessant ectopic atrial tachycardia is reversible after successful treatment. This stresses the necessity of recognizing such arrhythmia as cause of primary heart failure. PMID:10959459

    Given that the variation in how regional adipose tissue handles and stores excess dietary energy has substantial cardiometabolic implications, ectopic fat distribution might be an important predictor of cardiometabolic and vascular risk, in addition to overall obesity itself. Conceptually, ectopic fat depots may be divided into systemically acting fat depots and locally acting fat depots. Systemically acting fat depots include visceral fat, fat in the liver, muscle, or neck, and subcutaneous fat. Accumulation in the abdominal visceral area, compared with overall obesity, has an equally or more important role in the development of cardiometabolic risk. Fat depots in liver/muscle tissue cause adverse cardiometabolic effects by affecting energy metabolism. Fat depots in lower-body subcutaneous areas may be protective regarding cardiometabolic risk, by trapping remnant energy. Fat accumulation in the neck is a unique type of fat depot that may increase cardiovascular risk by increasing insulin resistance. Locally acting fat depots include pericardial fat, perivascular fat, and renal sinus fat. These fat depots have effects primarily on adjacent anatomic organs, directly via lipotoxicity and indirectly via cytokine secretion. Pericardial fat is associated with coronary atherosclerosis. Perivascular fat may play an independent role in adverse vascular biology, including arterial stiffness. Renal sinus fat is a unique fat depot that may confer additional cardiometabolic risk. Thus, ectopic fat depots may contribute to the understanding of the link between body composition and cardiometabolic risk. In this review, we focus on the role and clinical implications of ectopic fat depots in cardiometabolic and vascular risk. PMID:24063931

    Depth maps are used in many applications, e.g. 3D television, stereo matching, segmentation, etc. Often, depth maps are available at a lower resolution compared to the corresponding image data. For these applications, depth maps must be upsampled to the image resolution. Recently, joint bilateral filters are proposed to upsample depth maps in a single step. In this solution, a high-resolution output depth is computed as a weighted average of surrounding low-resolution depth values, where the weight calculation depends on spatial distance function and intensity range function on the related image data. Compared to that, we present two novel ideas. Firstly, we apply anti-alias prefiltering on the high-resolution image to derive an image at the same low resolution as the input depth map. The upsample filter uses samples from both the high-resolution and the low-resolution images in the range term of the bilateral filter. Secondly, we propose to perform the upsampling in multiple stages, refining the resolution by a factor of 2×2 at each stage. We show experimental results on the consequences of the aliasing issue, and we apply our method to two use cases: a high quality ground-truth depth map and a real-time generated depth map of lower quality. For the first use case a relatively small filter footprint is applied; the second use case benefits from a substantially larger footprint. These experiments show that the dual image resolution range function alleviates the aliasing artifacts and therefore improves the temporal stability of the output depth map. On both use cases, we achieved comparable or better image quality with respect to upsampling with the joint bilateral filter in a single step. On the former use case, we feature a reduction of a factor of 5 in computational cost, whereas on the latter use case, the cost saving is a factor of 50.

    Heterotopic pregnancy is defined as the simultaneous occurrence of intrauterine and ectopic pregnancy, either of which may be single or multiple. It occurs in up to 1% of pregnancies after in vitro fertilization and embryo transfer. This article reports 2 rare cases of heterotopic pregnancy after in vitro fertilization and presents a literature review. In the first case, a 28-year-old woman had previous laparoscopic bilateral total salpingectomy for a right tubal pregnancy and a left hydrosalpinx. However, she had ovarian heterotopic pregnancy after a third in vitro fertilization cycle. Emergency laparotomy was performed. The synchronous intrauterine pregnancy continued with no further complications and ended in the delivery of a singleton term pregnancy. The second case combined interstitial and intrauterine pregnancies after bilateral tubal ligation for hydrosalpinges followed by in vitro fertilization and frozen embryo transfer. The possibility of heterotopic pregnancy after bilateral total salpingectomy/tubal ligation, although extremely rare, should also be considered by gynecologists when they treat an in vitro fertilization patient even though an intrauterine pregnancy has been confirmed.

Only nine middle turbinate, three inferior turbinate and one inferior turbinate osteoma cases have been reported to date. The present case report describes the management and follow-up of symptomatic bilateral inferior turbinate osteoma. A 60-year-old female presented with symptoms of bilateral nasal obstruction and right-sided epiphora. Radiological investigation found hypertrophic bony changes involving both inferior turbinates. The patient was managed successfully by endoscopic inferior turbinectomies in order to achieve a patent airway, with no further recurrence of tumour after 3 months postoperatively. To the best of our knowledge, this is the first reported case of bilateral inferior turbinate osteoma. We describe a safe and minimally invasive method of tumour resection, which has a better cosmetic outcome compared with other approaches. PMID:27534890

    Simultaneous or subsequent bilateral thalamic haemorrhage is rare, and most reported cases are from Asian countries. An 80-year-old white Cuban man, with a history of arterial hypertension, suffered sudden onset of right hemiparesis. Computed tomography (CT) scan showed a left posteromedial thalamic haemorrhage. Two days later his condition suddenly deteriorated: blood pressure was 220/105 mm Hg, he was stuporous and tetraplegic, respiration was ataxic, and his gaze was fixed and deviated downward and inward. CT scan showed haemorrhages in both thalami, extending to the ventricles. 32 h later the patient died. There are few previous publications of simultaneous or subsequent bilateral thalamic haemorrhages and this is the first report involving a Hispanic patient. Prognosis in patients with bilateral thalamic haemorrhage is poor, and the mechanism underlying the development of subsequent and symmetrical bleeding is not clear. PMID:21709830

    2016-01-01

    Medullary thyroid carcinoma (MTC) has been described as a source of ectopic ACTH secretion in patients with Cushing’s syndrome. This is an infrequent association, occurring in less than 1% of MTC cases. Among these, it is even more unusual for an initial diagnosis of hypercortisolism to lead to the discovery of underlying MTC. Here we present a case of a patient with weakness, diarrhea, and hypokalemia who was found first to have Cushing’s syndrome and later diagnosed with metastatic MTC. The patient was treated initially with oral agents to control his hypercortisolism, then with an etomidate infusion after experiencing intestinal perforation. He also received vandetanib therapy targeting his underlying malignancy, as this has been shown to reverse clinical signs of Cushing’s syndrome in patients with MTC and subsequent ectopic ACTH secretion. Bilateral adrenalectomy was ultimately required. Medullary thyroid carcinoma should be considered in patients presenting with Cushing’s syndrome due to ectopic ACTH secretion, and a multimodality treatment approach is often required. PMID:27141514

    Abstract Introduction: Parathyroid crisis due to ectopic parathyroid adenomas can pose diagnostic and management challenges, since it is quite rare in clinical practice. Clinical Findings/Patient Concerns: A 67-year-old Chinese male presented as a parathyroid crisis due to an ectopic mediastinal parathyroid adenoma with his serum calcium and PTH markedly increased in short time. An ultrasonography and computed tomography (CT) scan of the neck did not reveal any parathyroid adenoma. Thoracic CT detected a contrast-enhanced mass in the mediastinum. Although the ectopic location is difficult to appreciate on anterior planar technetium-99m-sestamibi scintigraphy views but has been accurately localized with single photon-emission computed tomography/computed tomography. After fluid resuscitation, loop diuretic, and calcitonin treatment, a thoracoscope surgery was performed. The histopathology of the mediastinal nodule was consistent with a parathyroid adenoma. Hypocalcemia due to hungry bone syndrome occurred after surgery and was resolved quickly with large-dose calcium and calcitriol supplementation. He is asymptomatic and has normal serum calcium and PTH levels on regular follow-up. Diagnoses: The ultrasonography, CT, sestamibi, and single photon-emission computed tomography/computed tomography provide limited sensitivity in the detecting ectopic parathyroid adenomas alone. The combination of these techniques has incremental value in localizing ectopic parathyroid adenomas over either technique alone. Conclusion: Any parathyroid crisis without parathyroid adenoma in the neck should alert physicians to search for ectopic locations through combination of imaging techniques. PMID:27741147

    Patients with bilateral urolithiasis diagnosed at their first visit were followed for at least one year after the start of treatment. In this retrospective study of 123 patients, the basic metabolic workup revealed no specific underlying cause of simultaneously occurring bilateral nephrolithiasis, and none of the currently used therapeutic regimes proved to be efficient in attaining clinically acceptable stone-free rates at the 3, 6 and 12-month follow-ups. Of 38 patients treated with extracorporeal shockwave lithotripsy (SWL), 21 underwent treatment of both kidneys and 10 (48%) were free of stones bilaterally after 12 months. All of the 17 patients treated with unilateral SWL failed to achieve a stone-free state on the contralateral side. In another group, treated with medication alone to minimize risks of stone recurrence, only 3 of 26 (11.5%) patients were stone-free on both sides 12 months after the start of medication. Since we achieved a stone-free state of both kidneys in no more than 12% of the non-medicated cases, it seems warranted to treat bilateral urolithiasis with SWL more frequently, particularly when patients cannot return regularly to the stone clinic for a longterm follow-up.

    The management of boys with undescended testes appears to be an increasingly common problem. While Scorer (1964) [11] reported an incidence of 0.8% of undescended testes in boys of one year of age, a recent survey (Radcliffe Hospital, Oxford, 1986) [18] suggests the incidence has risen to as high as 1.6%. While the etiology may be varied, it is quite clear that many cases represent disturbances of the hypothalamic-pituitary-gonadal axis and may represent a forme fruste of hypogonadotropic hypogonadism [3]. Bilateral undescended testes might logically appear to represent the worst end of such an endocrinopathy. Indeed, a review of the experience at The Children's Hospital of Philadelphia [12] of boys with bilateral undescended testes indicated a greater number of CNS abnormalities (P = 0.0000) than in boys with unilateral undescended testes (Table 1). Also consistent with bilateral cryptorchid testes representing the most severe end of the spectrum was the reported findings from that study that bilateral undescended testes also exhibit a significantly greater number of associated G-U anomalies (P = 0.0004).

    Introduction Renal lymphangiomatosis is a rare congenital benign disease of renal lymphatic system, here we are presenting a very rare form of disease which is bilateral form. Presentation of the case A young adult presented to our clinic after being referred from primary care clinic with intermittent bilateral flank pain and no other symptoms after extensive radiological investigations diagnosis has been made and confirmed by radiological finding of disease. Active treatment usually preserved for complex cases and for the complications of the disease but in our patient as needed analgesia worked well in controlling his intermittent pain and his wish not to pursue any intervention. The vague presentation with initial imaging rising suspicion of renal tumor or complex renal cyst might cause psychological street on the patient, which our patient had, but reassurance after extensive radiological work up relive that's stress. Discussion Although it is very rare disease to be bilateral but wide variety of other differential diagnoses make importance of disease recognition and accurate diagnosis is the key. Conclusion Renal lymphangiomatosis is a rare benign disease of renal lymphatic, which usually affect one side, but bilateral form is very rare form, which may raise the suspicions of genetic form of renal malignancy. Accurate diagnosis requires work up to role out malignant and other renal tumor, which require active surgical management. PMID:26719997

    Ectopic lymphoid structures (ELS) often develop at sites of inflammation in target tissues of autoimmune diseases, such as rheumatoid arthritis, Sjögren’s syndrome, multiple sclerosis, myasthenia gravis, and systemic lupus erythematosus. ELS are characterized by the formation of organized T/B cells aggregates, which can acquire follicular dendritic cells network supporting an ectopic germinal center response. In this review, we shall summarize the mechanisms that regulate the formation of ELS in tertiary lymphoid organs, with particular emphasis on the role of lymphoid chemokines in both formation and maintenance of ELS, the role of emerging positive and negative regulators of ELS development and function, including T follicular helper cells and IL-27, respectively. Finally, we shall discuss the main functions of ELS in supporting the affinity maturation, clonal selection, and differentiation of autoreactive B cells contributing to the maintenance and perpetuation of humoral autoimmunity.

    Neuroendocrine tumors (NETs) and ectopic adrenocorticotropic hormone (ACTH) syndrome are frequent in adult patients. However, primary intracranial NETs, exhibiting immunonegativity for ACTH, high serum ACTH level and treated with anterior skull base reconstruction, are rare and complicated. We herein present a case of a primary intracranial NET immunonegative for ACTH, resulting in ectopic ACTH syndrome. A 40-year-old woman presented with intermittent rhinorrhea, rapid weight gain, polydipsia, polyuria, hypertension, dimness, bilateral exophthalmus, diminution of vision in the left eye and pigmentation of the skin of the face and trunk. Computed tomography (CT) and magnetic resonance imaging scans revealed a sizeable enhancing tumor in the anterior cranial fossa, which infiltrated the sphenoid and ethmoid sinuses bilaterally, the left maxillary sinus and the nasal cavity. Abdominal CT scans revealed bilateral adrenal hyperplasia. The biochemical findings included hypokalemia and high glucose, cortisol, plasma ACTH, 24-h urinary free cortisol and testosterone levels. The neoplasm was exposed through a right frontal craniotomy, while anterior skull base reconstruction was performed during surgery. The intracranial surgery achieved gross removal of the tumor; however, part of the tumor remained in the nasal cavity. Histopathological examination of the surgical specimen confirmed the diagnosis of a low-grade small-cell NET, exhibiting immunonegativity for ACTH. A postoperative abdominal CT scan demonstrated bilateral regression of the adrenal gland hyperplasia and the serum ACTH level returned to normal after 16 days. To the best of our knowledge, there are no previous reports of primary intracranial NETs, immunohistochemically negative for ACTH, resulting in ectopic ACTH syndrome. PMID:27330775

    Spontaneous cervical artery dissection (sCAD) is a major cause of ischemic stroke in young adults. Frequently, sCAD involves multiple neck arteries, accounting for 13%-28% of the total sCAD cases. However, little is known about factors related to multiple sCAD. In this case, a 52-year-old man was admitted due to headache without aura. There was a personal history of migraine with aura and a family history of similar symptoms. The patient's younger brother had a left vertebral artery (VA) dissecting aneurysm and underwent endovascular occlusion of his parent artery at the age of 48. Magnetic resonance imaging of our admitted patient showed hyperintensities in the right internal carotid artery (ICA) without acute infarction, and magnetic resonance angiography revealed a narrowing of the right ICA. Angiography was then performed, which showed a trace of dissection of the left ICA and both VAs as well as the right ICA. The patient did not fulfill any major criteria of collagen vascular disease such as Ehlers-Danlos syndrome type IV or Loeys-Dietz syndrome. The data in our patient are quite similar to those reported in patients with single-nucleotide polymorphism (SNP) of PHACTR1. Obtaining the patient's informed consent, we analyzed a common SNP variation in the rs9349379[G] allele (PHACTR1), which has been reported to be associated with a lower risk of sCAD. PMID:27216377

    We report herein on a case of ectopic cervical thymus in a 5-year-old boy and the literature is reviewed. Swelling of the right neck was seen in the patient in his newborn period and it was diagnosed as cystic disease of the neck in a previous hospital at 4 months of age. Ultrasonography (US) and MRI revealed a cervical tumor consisting of a solid component in our hospital, and histopathologic examination showed no evidence of malignancy. The lesion revealed almost no change in size but showed a mosaic pattern on US, whereon the parents agreed to the removal of the tumor. Intraoperatively, the tumor could be easily dissected from the surrounding tissue and resected. The pathological diagnosis was normal thymic tissue. The postoperative course was uneventful and no complication or immunological disorders were seen. A cervical ectopic thymus is a congenital lesion that results from abnormal thymic migration during embryogenesis. Most patients are asymptomatic and the condition is found incidentally. Preoperative diagnosis of cervical ectopic thymus in children is rarely made, so surgical treatment is the definitive means of pathological diagnosis. This disease should be listed in the differential diagnosis for neck masses in children, and should be suspected when the mosaic pattern is detected in the lesion on US.

    Ectopic fascioliasis (EF) has direct and indirect effects on both humans and animals. The phenomenon of EF was individual cases in the period from 1950 up to the end of last century. From the period of 2000 up to 2006, plenty of researches were on EF in the developed and undeveloped countries. Nineteen EF cases infected with the immature and few with the mature worms were 13 females and 6 males. Three cases of lymphatic, pleural and breast fascioliasis reached the adults and laid their eggs in a lymph node in the cervical region pleural cavity and breast tissues. Until recent, knowledge about the ectopic fascioliasis pathway is little. Fasciola hepatica was the commonest species in most cases. The effect of fascioliasis might be direct to liver as ectopic foci or indirect on other organs due to the metabolites and secretory excretory products. All ages and both sexes were EF infected. Watercress topped the list of water plants born encysted metacercariae followed by lettuce, mint, and alfalfa. Nearly 24 million Egyptians at risk and about 800,000 were infected. On the global scale, about 180 million are at risk of infection. PMID:21268530

  14. Simulation of Ectopic Pacemakers in the Heart: Multiple Ectopic Beats Generated by Reentry inside Fibrotic Regions

    The inclusion of nonconducting media, mimicking cardiac fibrosis, in two models of cardiac tissue produces the formation of ectopic beats. The fraction of nonconducting media in comparison with the fraction of healthy myocytes and the topological distribution of cells determines the probability of ectopic beat generation. First, a detailed subcellular microscopic model that accounts for the microstructure of the cardiac tissue is constructed and employed for the numerical simulation of action potential propagation. Next, an equivalent discrete model is implemented, which permits a faster integration of the equations. This discrete model is a simplified version of the microscopic model that maintains the distribution of connections between cells. Both models produce similar results when describing action potential propagation in homogeneous tissue; however, they slightly differ in the generation of ectopic beats in heterogeneous tissue. Nevertheless, both models present the generation of reentry inside fibrotic tissues. This kind of reentry restricted to microfibrosis regions can result in the formation of ectopic pacemakers, that is, regions that will generate a series of ectopic stimulus at a fast pacing rate. In turn, such activity has been related to trigger fibrillation in the atria and in the ventricles in clinical and animal studies. PMID:26583127

    Purpose: To describe a case of bilateral presumed tuberculous choroiditis which resolved promptly with a short course of antituberculous therapy. Case Report: A 44-year-old lady presented with bilateral visual loss of 8 months’duration. Considering the presence of pan-uveitis, severe macular edema, multifocal leakage on fluorescein angiography, positive tuberculin skin test, and after excluding other diseases, she underwent anti-tuberculous therapy (ATT) for disseminated choroiditis due to presumed ocular tuberculosis. She improved promptly and completely. There were no signs of relapse 18 months after completion of the treatment course. In a young patient with disseminated choroiditis and relatively short duration of symptoms, a course of ATT for 6 months may effectively treat the disease preventing relapse for a considerable period of time. Conclusion: In Presumed Tuberculous chroiditis early diagnosis is crucial for prompt and complete improvement. PMID:27413507

  16. Bilateral parotid neoplasms.

    PubMed

    Williams, C

    1980-09-01

    We are reporting what we believe to be the second case of bilateral parotid neoplasm occuring synchronously with differing histologies. We believe that this neoplasm may represent a specific propensity of parotid tissue in a given individual to develop neoplasia in a multipotential glandular organ subject to many neoplastic diseases. There also exists the possibility that this condition may represent an immune deficiency specific to the parotid gland. The case reports that have been reviewed demonstrate that a secondary neoplasm may arise from benign mixed tumors. We question whether this is an example of monistic origin of acinic cell tumor from a mixed-cell tumor or, perhaps, dualistic expression for this salivary gland to develop a multiplicity of anaplastic and metaplastic growth variants. In approaching a case with bilateral parotid involvement, the physician must be aware of the rare possibility that benign and malignant tumors may coexist. He must be prepared to proceed with more radical extirpation than simple superficial parotidectomy.

The goal of this article is to report one case of spontaneous bilateral lumbar Petit's hernia treated with open surgery.

  19. Multispectral bilateral video fusion.

    2007-05-01

    We present a technique for enhancing underexposed visible-spectrum video by fusing it with simultaneously captured video from sensors in nonvisible spectra, such as Short Wave IR or Near IR. Although IR sensors can accurately capture video in low-light and night-vision applications, they lack the color and relative luminances of visible-spectrum sensors. RGB sensors do capture color and correct relative luminances, but are underexposed, noisy, and lack fine features due to short video exposure times. Our enhanced fusion output is a reconstruction of the RGB input assisted by the IR data, not an incorporation of elements imaged only in IR. With a temporal noise reduction, we first remove shot noise and increase the color accuracy of the RGB footage. The IR video is then normalized to ensure cross-spectral compatibility with the visible-spectrum video using ratio images. To aid fusion, we decompose the video sources with edge-preserving filters. We introduce a multispectral version of the bilateral filter called the "dual bilateral" that robustly decomposes the RGB video. It utilizes the less-noisy IR for edge detection but also preserves strong visible-spectrum edges not in the IR. We fuse the RGB low frequencies, the IR texture details, and the dual bilateral edges into a noise-reduced video with sharp details, correct chrominances, and natural relative luminances.

    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/m(2) 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 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.

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    Wilms' tumor occurs in 5-10 % of all cases of nephroblastoma. The metachronous form represents 2-3 % of cases. Most (96.2 %) metachronous tumors appear within the first 5 years of the primary tumor. Associated malformations are more common in bilateral cases. Metachronous tumors are a therapeutic challenge. We describe the case of an 11-year-old girl with left hemihypertrophy. The diagnosis was metachronous relapse of Wilms' tumor 7 years after the first diagnosis. The patient received five courses of preoperative chemotherapy and tumorectomy was performed. Because of post-surgical complications, nephrectomy was performed on her only kidney. Since she is anephric, the patient is in chronic renal failure and is dependent on dialysis. Treatment with carboplatin and etoposide was continued after surgery and the patient is currently in complete remission. The appearance of a metachronous Wilms' tumor 5 years after that of the primary tumor is rare. When a contralateral tumour develops, chemotherapy must be given until the size of the tumor is reduced in order to preserve renal function and avoid dialysis. In patients with chronic renal failure caused by bilateral nephrectomy, ongoing treatment with dialysis support can be achieved through the choice of effective drugs and knowledge of their pharmacokinetics and pharmacodynamics.

    “Humanized” mice offer a window into aspects of human physiology that are otherwise inaccessible. The best available methods for liver humanization rely on cell transplantation into immunodeficient mice with liver injury but these methods have not gained widespread use due to the duration and variability of hepatocyte repopulation. In light of the significant progress that has been achieved in clinical cell transplantation through tissue engineering, we sought to develop a humanized mouse model based on the facile and ectopic implantation of a tissue-engineered human liver. These human ectopic artificial livers (HEALs) stabilize the function of cryopreserved primary human hepatocytes through juxtacrine and paracrine signals in polymeric scaffolds. In contrast to current methods, HEALs can be efficiently established in immunocompetent mice with normal liver function. Mice transplanted with HEALs exhibit humanized liver functions persistent for weeks, including synthesis of human proteins, human drug metabolism, drug–drug interaction, and drug-induced liver injury. Here, mice with HEALs are used to predict the disproportionate metabolism and toxicity of “major” human metabolites using multiple routes of administration and monitoring. These advances may enable manufacturing of reproducible in vivo models for diverse drug development and research applications. PMID:21746904

    Aim: To assess the outcome of patients undergoing bilateral adrenalectomy for Cushing's syndrome (CS). Methods: All patients who underwent bilateral adrenalectomy for CS at the Department of Endocrine Surgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences hospital between 1991 and 2013 were included. Medical records were reviewed to obtain patient characteristics and follow-up data. Results: Twenty-seven patients were studied. Mean age was 28.74 ± 12.95 years (range 9–60), male:female ratio was 1.7:1. About half that is, 48.19% were of Cushing's disease (failed trans-sphenoidal surgery [TSS]), 37.04% were of ectopic CS (ECS), and 14.81% were of CS due to bilateral adrenal pathology. Median follow-up period was 80.5 months. Before surgery, 74.1% patients had body mass index > which after surgery declined to <25 in 75% of them. Hypertension was present in 85.2% and after surgery resolved in 40%. Diabetes mellitus was present in 44.4% and after surgery resolved in 33% of them. Hirsutism and proximal muscle weakness were present in 55.6% and 70.4% patients, respectively, and after surgery improved markedly in all patients. Adrenal crisis developed in 36.3% and Nelson's syndrome in 41.7% patients during follow-up. Three patients died in perioperative period while three succumbed to the disease during follow-up. Two patients developed recurrence of endogenous cortisol production during the follow-up period. Conclusions: Bilateral adrenalectomy is a valid treatment option for palliating severe symptoms in Pituitary Cushing's with failed TSS and unlocalized ECS but the procedure is curative for CS due to bilateral adrenal disease. Overall morbidity and mortality is higher than other endocrine operations. Co-morbidities tend to be more severe and are a risk factor for mortality during the time patient survives. PMID:26693437

    Acromegaly secondary to extra-pituitary tumors secreting growth hormone releasing hormone (GHRH) is rarely encountered. We review the literature on ectopic acromegaly and present the index report of ectopic acromegaly secondary to GHRH secretion from a mediastinal paraganglioma. Clinical and pathological manifestations and therapeutic management of 99 patients with ectopic acromegaly are reviewed. Acromegaly secondary to ectopic GHRH secretion is usually caused by a neuroendocrine tumor in the lung and pancreas. We report an additional cause of ectopic acromegaly from a mediastinal paraganglioma. Diagnostic criteria of ectopic GHRH syndrome include biochemical and pathologic tumoral confirmation of GHRH secretion and expression. Management of ectopic acromegaly consists of surgical resection of the primary tumor and biochemical normalization, with possible adjuvant use of somatostatin analogs. The review demonstrates that there are several tumor types, including paragangliomas which may secrete GHRH, leading to acromegaly. Clinical and laboratory manifestations of the syndrome and challenges in diagnosis and management of these rarely encountered patients require early diagnosis and appropriate treatment to prevent long-term morbidity and mortality with ectopic acromegaly.

    Ectopic thyroid is a congenital defect in which the thyroid gland is located away from the usual pretracheal location. Dual ectopic thyroid, which consists of two foci of thyroid tissue, is very rare. In this case dual ectopic thyroid with subclinical hypothyroidism in a 10-year-old-girl was reported. The absence of the thyroid gland in the pretracheal location was revealed by ultrasonography (USG). Two foci of ectopic thyroid tissue located at the base of the tongue and infrahyoid region were determined by Technetium-99m pertechnetate thyroid scintigraphy. It can be concluded that if the thyroid gland is not visible by USG, ectopic thyroid tissue should be evaluated with scintigraphy. PMID:25541934

    2003-07-01

    Ectopic or tubal pregnancy presents a medical emergency that requires prompt treatment in order to contain risks of maternal death and morbidity, including loss of future fertility. Medical circumstances involving individual patients and resources of the prevailing health care system will determine the options and means of treatment. Termination of ectopic pregnancy does not constitute or directly implicate abortion. Any practice of deliberately delaying treatment of reliably diagnosed ectopic pregnancy, on non-clinical grounds, until rupture of the fallopian tube has occurred or is imminent, in order to justify termination of the ectopic pregnancy on grounds of saving the patient's life, is unethical and illegal. Those who undertake or counsel deliberate delay of medically-indicated treatment can be charged with criminal offences and civil (non-criminal) liability, and medical professional misconduct. On reliable diagnosis, prompt treatment to remove ectopic pregnancy is legally justified, and ethically and legally required.

    Of 356 women undergoing sonography to diagnose or rule out an ectopic gestation, data sufficient to assign a final diagnosis were available on 260 of them. Ectopic gestation was diagnosed in 25 cases in this group and intrauterine pregnancy in 99, while the remaining 136 patients were found not to be pregnant. During sonography, ectopic gestations were suspected or diagnosed in 27 instances: In 17 cases this was in agreement with the final diagnosis, but neither an intrauterine nor an extrauterine gestation existed in 10 cases, although neoplastic or inflammatory masses were present. Of the 25 patients with the final diagnosis "ectopic pregnancy," this was not detected with sonography in 8 instances. Intrauterine pregnancies were diagnosed by sonar in 94 of the 99 cases. Although reliable sonar identification of ectopic gestation is not always possible, sonography is helpful in diagnosing intrauterine pregnancy so that surgical intervention can be avoided.

    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 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.

    Background. Purely ectopic pituitary adenomas are exceedingly rare. Here we report on a patient that presented with an incidental clival mass thought to be a chordoma. Endonasal resection, tumor pathology, and endocrinology workup revealed a prolactinoma. Case Presentation. A 41-year-old male presented with an incidental clival lesion presumed to be a chordoma. On MRI it involved the entire clivus, extended laterally to the petroclival junction, and invaded the cavernous sinuses bilaterally, encasing both internal carotid arteries, without direct extension into the sella. Intraoperatively, it was clear that the tumor originated from the clivus and that the sellar dura was completely intact. Frozen-section pathology was consistent with a pituitary adenoma. Immunostaining was positive for synaptophysin and prolactin with a low Ki-67 index, suggestive of a prolactinoma. Additional immunohistochemical stains seen in chordomas (EMA, S100, and Brachyury) and other metastatic tumors were negative. A postoperative endocrine workup revealed an elevated serum prolactin of 881.3 ng/mL (normal < 20). Conclusions. In conclusion, it is crucial to maintain an extensive differential diagnosis when evaluating a patient with a clival lesion. Ectopic clival pituitary adenomas, although rare, may warrant an endocrinological workup preoperatively as the majority may respond to medical treatment.

The current literature on pseudogout and gout after both total and partial knee replacement is summarized. A case of bilateral pseudogout 8 years after initial total knee arthroplasty (TKA) is used to highlight the clinical characteristics and treatment options for this underrecognized condition. Presentation mimicked a late septic joint arthroplasty with sudden onset of pain and effusion. The patient was treated successfully with an arthrotomy, debridement, synovectomy, polyethylene insert exchange, oral steroids, and nonsteroidal anti-inflammatories. There are no other reported cases of bilateral pseudogout after bilateral TKA.

    During a period of 4 years, 1974-77, in Uppsala county; Sweden, 203 women underwent surgery for ectopic pregnancy with histological proof of the diagnosis. For the female population of fertile age this corresponds to 0.11 ectopics per 100 women 15-44 years of age, or 1.08 per 100 notified pregnancies, or 1.53 per 100 births. Fifty-five of the women with ectopic pregnancy were using an intrauterine device (IUD) (48 a copper-bearing IUD and 7 some other type of device), and 6 women used a low dose progestogen contraceptive. For users of copper-bearing IUDs the risk of an ectopic pregnancy was estimated to be 0.15 per 100 women years. When comparing this latter risk rate with the overall incidence rate of 0.11, it must be observed that the populations forming the denominator in these two rates differ with respect to some crucial characteristics. Nulliparity and predisposing factors were found statistically significantly more often in non-IUD-users with an ectopic pregnancy than in IUD-users. Such predisposing factors may be less prevalent in IUD-users, as in other populations. This may explain why ectopic pregnancy has been found to occur less frequently than theoretically expected among IUD-users. The "ectopic preventing" capacity of the IUD may therefore be considerably lower than has been previously claimed.

    Introduction Extra-uterine pregnancy or Ectopic Pregnancy (EP) is a major health problem for pregnant women, presenting as a potentially life-threatening emergency in the first trimester. There are three major options for the treatment of EP: expectant management, surgical treatment and medical management. The presence of free intraperitoneal fluid in EP-diagnosed patients is crucial for treatment planning and evaluation. Aim To compare the outcomes of both the expectant man-agement and medical treatment with methotrexate (MTX) in ectopic pregnancies with free intraperitoneal fluid. Materials and Methods This retrospective cohort study inclu-ded a total of 91 ectopic pregnancies with or without rupture in which the women had initial free intraperitoneal fluid and were haemodynamically stable. Serial β-HCG measurements were used to assess the outcome of expectant management and medical treatment with MTX. For the statistical analysis, the SPSS statistical software package, version 22.0 (Chicago, IL, USA), was used. For the quantitative variables that were not distributed normally, the Kruskal-Wallis test and the Mann-Whitney U test were performed for the evaluation of differences between the groups. Results It was observed that the success rate with expectant management was 81% (initial β HCG concentration 626±443 mIU/mL). With a single dose of MTX, it was 76% (initial β HCG concentration 2124±1647 mIU/mL) and with a total single or double dose of MTX, it was 88% (initial β HCG concentration 2252±78 mIU/mL) from among EP with or without rupture in women with initial free intraperitoneal fluid during diagnosis. There was no significant difference between the groups with regard to ultrasonography findings. Conclusion Expectant management or medical treatment with methotrexate should be the first line treatment for ectopic pregnancies with initial free intraperitoneal fluid, albeit with rupture, in patients who are haemodynamically stable, along with

    Radioimmunoassay of beta-hCG was used to diagnose an ectopic pregnancy in a 30 year old patient and the site of pregnancy was determined by ultrasonography. A salpingostomy was performed; the ectopic pregnancy and the residual trophoblastic tissue were removed. Six weeks later a right salpingectomy was performed to remove persistent trophoblastic tissue. Histologic examination of the surgical specimen demonstrated viable chorionic villi. Serial measurements of beta-hCG are recommended following conservative surgery for ectopic gestation to assure the patient and the surgeon that the tube contains no residual products of conception.

    Background and Objectives: Retroperitoneal laparoscopic pyelolithotomy was performed in an ectopic pelvic kidney with renal pelvis calculi. Methods and Results: Laparoscopic pyelolithotomy was successfully performed in an ectopic pelvic kidney by using the retroperitoneal route. The total operation time was 130 minutes, and the estimated blood loss was <50mL. The patient was discharged on the second postoperative day without any complications. Conclusion: Laparoscopic pyelolithotomy is an effective treatment option for management of stones in the pelvis of an ectopic pelvic kidney. The retroperitoneal route may help to avoid intraoperative and postoperative complications. PMID:23477189

Laparoscopic management avoids open surgery and associated morbidity and offers added safety. We report the management of symptomatic stones in a pelvic ectopic kidney lying anterior to the L5 vertebra and sacrum by transmesocolic laparoscopic pyelolithotomy in an 11-year-old child. Complete stone clearance was achieved with no complications and an uneventful postoperative recovery. The patient was discharged 72 hours after the surgery. PMID:17761093

    In a statistical analysis of 360 cases of ectopic pregnancy admitted to the Montreal General Hospital over a 20-year period ending December 1964, ectopic gestation occurred once in every 83 admissions to the gynecological service. This incidence has remained constant over the years. Only one out of four patients had had more than one child and 30% of the patients had absolute or relative infertility. Diagnosis was delayed or not made in 58 patients. There was evidence that neurogenic factors play a role in the etiology of ectopic gestation. Ten per cent of the patients had had a previous operation for the same condition. Symptomatology is variable and the possibility of ectopic pregnancy must never be overlooked in a woman of child-bearing age. Once the diagnosis is made the treatment is early operation. The morbidity rate in this series was 28% and there was one death. PMID:6017696

    Image smoothing is a fundamental operation in computer vision and image processing. This work has two main thrusts: (1) implementation of a bilateral filter suitable for use in smoothing, or denoising, 3D volumetric data; (2) implementation of the 3D bilateral filter in three different parallelization models, along with parallel performance studies on two modern HPC architectures. Our bilateral filter formulation is based upon the work of Tomasi [11], but extended to 3D for use on volumetric data. Our three parallel implementations use POSIX threads, the Message Passing Interface (MPI), and Unified Parallel C (UPC), a Partitioned Global Address Space (PGAS) language. Our parallel performance studies, which were conducted on a Cray XT4 supercomputer and aquad-socket, quad-core Opteron workstation, show our algorithm to have near-perfect scalability up to 120 processors. Parallel algorithms, such as the one we present here, will have an increasingly important role for use in production visual analysis systems as the underlying computational platforms transition from single- to multi-core architectures in the future.

    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.

    In this case report we present an adolescent girl who was referred to our radiology department for assessment with advanced magnetic resonance (MR) imaging on suspicion of low-grade quadrigeminal cistern neoplasm on 1.5 Tesla MR examination. We were able to evaluate detailed cerebellar anatomy more clearly, and detected that the lesion was compatible with ectopic cerebellar tissue (a very rare developmental variation) on submillimetric 3-dimensional (3D) images from a 3 Tesla MR unit which has a 32-channel head coil. Our findings were further supported by diffusion tensor imaging which clearly indicated that the lesion was a part of the cerebellum. Furthermore, MR spectroscopic metabolite ratios were in accordance with the characteristics of normal neuronal tissue. As far we know there is no published report that contains similar findings to those of our patient. In conclusion, cranial MR images, if possible in 3D format (with very small isotropic voxels) should be obtained for the precise diagnosis of the lesions located in this region; in addition, the differential diagnostic list should be well known and advanced imaging techniques should be used when necessary.

    During the 4-year period of 1984 to 1987, 102 women with ectopic pregnancy (EP) underwent second-look laparoscopy 6 to 10 weeks after EP surgery. Benefits of this procedure, e.g., adhesiolysis and/or selection of women for further fertility interventions (in vitro fertilization [IVF], gamete intrafallopian transfer [GIFT], tubal microsurgery), were evaluated. On the basis of the second-look laparoscopy, 13% of the women were offered tubal microsurgery and 14% recommended for IVF. Patients without risk factors for EP developed adhesions as frequently as those with known risk factors and no specific surgical procedure was correlated to impairment of the pelvic status. Almost 40% of the patients presented with an impairment of adhesions on the affected side compared with the status at the time of EP surgery. Lysis of adhesions was performed during the second-look laparoscopy in 42 patients (41%). We conclude that second-look laparoscopy should be recommended to all EP patients with a desire for pregnancy. PMID:2138569

  4. Gamma probe-assisted excision of an ectopic parathyroid adenoma located within the thymus: case report and review of the literature

    PubMed Central

    2014-01-01

    Primary hyperparathyroidism due to parathyroid adenomas may be associated with ectopic parathyroid gland localization in 20-25% of the patients. We report herein the excision of an ectopic parathyroid adenoma which was detected in the thymus gland by gamma probe intraoperatively. A 38-year-old patient presented to our clinic with a history of bilateral nephrolithiasis, chronic hypercalcaemia, and PTH elevation. A combination of Technetium-99 m sestamibi scintigraphy and Computed Tomography scan of the chest and neck revealed an ectopic parathyroid adenoma of 8.5 mm in its greatest dimension. The patient underwent sternotomy and the adenoma was found within the right lobe of the thymus gland with the intraoperative use of gamma probe. PTH detection and frozen biopsy were performed during surgery and confirmed the successful excision of the adenoma, while mild hypocalcaemia was noticed postoperatively. We conclude that accurate preoperative and intraoperative localization of an ectopic parathyroid adenoma is crucial to successful surgery. The use of at least two diagnostic modalities before surgical excision minimizes the risk of re-operation for recurrent hyperparathyroidism, while the intraoperative use of gamma probe offers a significant advantage over conventional techniques by reducing surgical time, morbidity and/or complications associated with surgical exploration.

    It is generally thought that simultaneous bilateral chest surgery carries a high morbidity. We reviewed the results of simultaneous (under one anesthesia) vs staged bilateral video-assisted thoracoscopic surgery (VATS) from a single institution over a 35-month period. From September 1992 to July 1995, we performed simultaneous bilateral VATS on 37 patients (31 males, six females, age ranging from 15 to 55 years) with spontaneous pneumothorax (20) for bleb resections and pleurodesis; thoracodorsal sympathectomy (12) for palmar hyperhidrosis and vasospastic disease; and metastatic sarcomas (five) for wedge lung resections. During the same period, nine patients with metachronous bilateral spontaneous pneumothorax had staged procedures, as did two with digital ischemic ulcers for sympathectomy and three with metastatic pulmonary osteosarcomas for resection. Mean postoperative hospital stays in days for the simultaneous groups were 3.3 for spontaneous pneumothorax, 2.1 for sympathectomy, and 1.5 for wedge resection, compared to 2.9, 2.5, and 2.2 for the staged groups, respectively (p > 0.05 by Mann-Whitney U tests). Likewise, pain assessment by visual analogue scale as well as analgesic requirement showed no significant difference between the simultaneous and the staged groups. We conclude that simultaneous VATS is not associated with increased morbidity or prolonged hospital stay compared to the staged counterparts and provides an attractive alternative to the median sternotomy, bilateral posterolateral thoracotomy, or transternal (clam-shell) thoracotomy for selected cases of simultaneous bilateral lung surgery.

The patient had intraabdominal bleeding and went through emergency surgery because of a ruptured interstitial pregnancy. The purpose of this case report is to recall the risk of interstitial pregnancy in pregnant women with a history of salpingectomy.

    Congenital variations in urinary tract anatomy present unique surgical challenges when they present without prior knowledge. Ectopic ureters occur as a rare anatomic variation of the urinary tract and are often associated with duplicated renal collecting systems. While the condition is uncommon, even more atypical is its discovery and subsequent diagnosis during surgical intervention for treatment of localized prostate cancer.We describe the intraoperative management of a unique case of bilateral ectopic ureters, with a right-sided ureter inserting into the prostate of a 54-year-old male undergoing robotic-assisted radical prostatectomy. While unknown at the time of surgery, this right-sided ureter was associated with a nonfunctioning right upper renal moiety of a duplex renal collecting system. This aberration was discovered intraoperatively and confirmed with imaging, and a robotic-assisted radical prostatectomy with right distal ureterectomy was performed. PMID:26266359

    Ectopic mineralization of connective tissues is a complex process leading to deposition of calcium phosphate complexes in the extracellular matrix, particularly affecting the skin and the arterial blood vessels and common in age-associated disorders. A number of initiating and contributing metabolic and environmental factors are linked to aberrant mineralization in these diseases, making the identification of precise pathomechanistic pathways exceedingly difficult. However, there has been significant recent progress in understanding the ectopic mineralization processes through study of heritable single-gene disorders, which have allowed identification of discrete pathways and contributing factors leading to aberrant connective tissue mineralization. These studies have provided support for the concept of an intricate mineralization/anti-mineralization network present in peripheral connective tissues, providing a perspective to development of pharmacologic approaches to limit the phenotypic consequences of ectopic mineralization. This overview summarizes the current knowledge of ectopic heritable mineralization disorders, with accompanying animal models, focusing on pseudoxanthoma elasticum and generalized arterial calcification of infancy, two autosomal recessive diseases manifesting with extensive connective tissue mineralization in the skin and the cardiovascular system.

    The detailed genetic analysis of the Duchenne/Becker muscular dystrophy gene is hindered by the large number of exons involved and their separation by huge introns. These problems can be overcome by the analysis of mRNA rather than genomic DNA and ectopic transcripts derived from peripheral blood lymphocytes provide a convenient source of material. Using reverse transcription and nested PCR, we show here a comprehensive strategy for the rapid and complete analysis of the coding sequences from complex genes and illustrate its potential by the identification of a hitherto undescribed single exon deletion.

  10. EphA4-Mediated Ipsilateral Corticospinal Tract Misprojections Are Necessary for Bilateral Voluntary Movements But Not Bilateral Stereotypic Locomotion

    In this study, we took advantage of the reported role of EphA4 in determining the contralateral spinal projection of the corticospinal tract (CST) to investigate the effects of ipsilateral misprojections on voluntary movements and stereotypic locomotion. Null EphA4 mutations produce robust ipsilateral CST misprojections, resulting in bilateral corticospinal tracts. We hypothesize that a unilateral voluntary limb movement, not a stereotypic locomotor movement, will become a bilateral movement in EphA4 knock-out mice with a bilateral CST. However, in EphA4 full knock-outs, spinal interneurons also develop bilateral misprojections. Aberrant bilateral spinal circuits could thus transform unilateral corticospinal control signals into bilateral movements. We therefore studied mice with conditional forebrain deletion of the EphA4 gene under control by Emx1, a gene expressed in the forebrain that affects the developing CST but spares brainstem motor pathways and spinal motor circuits. We examined two conditional knock-outs targeting forebrain EphA4 during performance of stereotypic locomotion and voluntary movement: adaptive locomotion over obstacles and exploratory reaching. We found that the conditional knock-outs used alternate stepping, not hopping, during overground locomotion, suggesting normal central pattern generator function and supporting our hypothesis of minimal CST involvement in the moment-to-moment control of stereotypic locomotion. In contrast, the conditional knock-outs showed bilateral voluntary movements under conditions when single limb movements are normally produced and, as a basis for this aberrant control, developed a bilateral motor map in motor cortex that is driven by the aberrant ipsilateral CST misprojections. Therefore, a specific change in CST connectivity is associated with and explains a change in voluntary movement. PMID:24719100

    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. Conclusion: 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. PMID:24303440

    Objective: To evaluate the plasma creatine phosphokinase (CPK) level after injection of methotrexate (MTX) as a predictor of treatment success in ectopic pregnancy (EP). Materials and methods: One hundred women treated with single dose of methotrexate for ectopic pregnancy were evaluated in a prospective study, for CPK and ß-subunit of human chorionic gonadotropin (ß-hCG) levels. They received intramuscular MTX at a dose of 50 mg/m2. The day of injection was considered as day 1 (D1). CPK level on the day of Methotrexate injection was compared between success group who were treated by a single MTX injection, and the unsuccessful groupwho were treated by two or three MTX injections or by surgery. Results: The success rate of single dose of MTX injection was 78 (78%). The mean of CPK was higher in success group than unsuccessful group. (86 ± 10.7 vs. 73 ± 11.8), the difference was significant (p = 0.04). The mean of ß-hCG was significantly lower in treatment success group than unsuccessful group (1421.3 ± 443.6 vs. 1925.6 ± 185.4, p = 0.01). Conclusion: The success of single dose of MTX treatment in ectopic pregnancy may be predicted by CPK levels and the higher levels of CPK may be useful for detecting of patients with successful response to MTX.

    Understanding the cellular organization and biology of fungal pathogens requires accurate methods for genomic integration of mutant alleles or fluorescent fusion-protein constructs. In Zymoseptoria tritici, this can be achieved by integrating of plasmid DNA randomly into the genome of this wheat pathogen. However, untargeted ectopic integration carries the risk of unwanted side effects, such as altered gene expression, due to targeting regulatory elements, or gene disruption following integration into protein-coding regions of the genome. Here, we establish the succinate dehydrogenase (sdi1) locus as a single “soft-landing” site for targeted ectopic integration of genetic constructs by using a carboxin-resistant sdi1R allele, carrying the point-mutation H267L. We use various green and red fluorescent fusion constructs and show that 97% of all transformants integrate correctly into the sdi1 locus as single copies. We also demonstrate that such integration does not affect the pathogenicity of Z. tritici, and thus the sdi1 locus is a useful tool for virulence analysis in genetically modified Z. tritici strains. Furthermore, we have developed a vector which facilitates yeast recombination cloning and thus allows assembly of multiple overlapping DNA fragments in a single cloning step for high throughput vector and strain generation.

    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.

    Splenic ectopic pregnancies are a rare cause of abdominal pain in reproductive-age women. A 21-year-old woman with worsening abdominal pain and a positive pregnancy test presented with hemoperitoneum and no intrauterine pregnancy on transvaginal ultrasound. After 2 nondiagnostic laparoscopies, a splenic pregnancy was diagnosed by computed tomography scan and abdominal ultrasound. Currently, diagnosis and treatment of splenic pregnancies involve exploratory surgery and splenectomy. We report the successful treatment of this splenic ectopic pregnancy with combined intramuscular plus ultrasound-guided percutaneous methotrexate injection, with preservation of the patient's spleen. Abdominal implantation must be considered in patients with pregnancy of unknown location, and in carefully selected patients splenic ectopic pregnancy can be successfully managed by minimally invasive methods.

    Solitary fibrous tumors occasionally present with hypoglycemia because of the excessive release of insulin-like growth factor II. We report the first case of pancreatic solitary fibrous tumor causing ectopic adrenocorticotropic hormone syndrome. An 82-year-old Japanese man presented with lower limb edema, uncontrolled hypertension, hypokalemia, and baseline hypercortisolism. Distal pancreatectomy was performed after the clinical diagnosis of a neuroendocrine tumor with ectopic secretion of adrenocorticotropic hormone. On histological examination, the tumor showed spindle cells in a fascicular arrangement. The diagnosis of the solitary fibrous tumor was confirmed by the identification of the NAB2-STAT6 fusion gene and positive immuno-histochemical staining for STAT6 and CD34. Using quantitative real-time polymerase chain reaction, mRNA that encoded proopiomelanocortin, precursor of adrenocorticotropic hormone, was detected. Proopiomelanocortin production through the demethylation of the promoter region Domain IV was detected. Pancreatic solitary fibrous tumors represent a new cause of ectopic adrenocorticotropic hormone syndrome. PMID:27585487

    Movement-related magnetic fields (MRMFs) accompanying left and right unilateral and bilateral finger flexions were studied in 6 right-handed subjects. Six different MRMF components occurring prior to, and during both unilateral and bilateral movements are described: a slow pre-movement readiness field (RF, 1-0.5 sec prior to movement onset); a motor field (MF) starting shortly before EMG onset; 3 separate "movement-evoked" fields following EMG onset (MEFI at 100 msec; MEFII at 225 msec; and MEFIII at 320 msec); and a "post-movement" field (PMF) following the movement itself. The bilateral topography of the RF and MF for both unilateral and bilateral movements suggested bilateral generators for both conditions. Least-squares fitting of equivalent current dipole sources also indicated bilateral sources for MF prior to both unilateral and bilateral movements with significantly greater strength of contralateral sources in the case of unilateral movements. Differences in pre-movement field patterns for left versus right unilateral movements indicated possible cerebral dominance effects as well. A single current dipole in the contralateral sensorimotor cortex could account for the MEFI for unilateral movements and bilateral sensorimotor sources for bilateral movements. Other MRMF components following EMG onset indicated similar sources in sensorimotor cortex related to sensory feedback or internal monitoring of the movement. The results are discussed with respect to the possible generators active in sensorimotor cortex during unilateral and bilateral movement preparation and execution and their significance for the study of cortical organization of voluntary movement.

    Of ectopic pregnancies encountered in clinical practice, more than 95% are located within the fallopian tube, and 2% to 4% are cornual. A cornual ectopic pregnancy is a serious clinical condition and poses diagnostic and therapeutic challenges. Thus, understanding the clinical course and treatment options is essential. The authors describe the case of a 29-year-old woman who presented to the Department of Obstetrics and Gynecology. The patient was suspected of having a cornual pregnancy, and a dermoid cyst had been detected during routine ultrasonography. In the absence of maternal symptoms, the clinical scenario is potentially dangerous and must be treated promptly and efficiently to decrease morbidity and mortality. PMID:27111785

    Benign ectopic thyroid tissue within the parotid salivary gland is very rare. A 32-year-old woman presented with a slowly-growing, painless mass in the parotid region. The mass, which was clinically diagnosed as a parotid tumour, was found at surgery to be cystic in nature. Histological examination showed thyroid tissue with secondary changes in the cyst wall and colloid in the lumen. On iodine isotope scan, the thyroid gland was found in its normal location. The possible origin of the ectopic thyroid tissue in the parotid salivary gland could be due to a common evolution of the thyroid and parotid glands, a heteroplasia or a metaplasia.

    Orthokeratinized odontogenic cyst (OOC) is a developmental cyst of jaw and was initially considered by the World Health Organization (1992) as the uncommon orthokeratinized variant of odontogenic keratocyst (OKC). However, studies have shown that OOC has peculiar clinicopathologic aspects when compared with other developmental odontogenic cysts, especially OKC. So orthokeratinized odontogenic cyst now stands out to be a distinct entity. Clinically, it occurs as a single cyst, shows a predilection for males and is most often found in the second to the fifth decade. Its bilateral occurrence is extremely rare. The purpose of the article is to present a rare case of bilateral OOC arising in the mandible and review the literature on bilateral occurrence of this lesion. PMID:25328309

    STUDY QUESTION Is bilateral tubotubal anastomosis a successful treatment in an outpatient patient population? SUMMARY ANSWER For women wanting children after tubal sterilization, bilateral tubotubal anastomosis is an effective outpatient treatment. WHAT IS KNOWN ALREADY With the current emphasis in reproductive medicine on high technology procedures, the effectiveness of female surgical sterilization reversal is often overlooked. Previous clinical studies of tubal sterilization reversal have been mostly retrospective analyses of small patient populations. STUDY DESIGN, SIZE, DURATION A cohort of women who underwent outpatient bilateral tubotubal anastomosis from January 2000 to June 2013 was followed prospectively until December 2014 to determine the proportions of women undergoing the procedure who became pregnant and who had live births. Data were collected at the time of pregnancy. Differences in pregnancy rates and live birth rates associated with age, race and sterilization method were evaluated. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 6692 women, aged 20–51 years, underwent outpatient bilateral tubotubal anastomosis. MAIN RESULTS AND THE ROLE OF CHANCE The crude overall pregnancy rate was 69%. The crude overall birth rate was 35%. Results varied according to age at sterilization reversal and the method of sterilization. Women under 30 years of age at reversal of ring/clip sterilizations had an 88% pregnancy rate and 62% birth rate. Pregnancy and birth rates declined as age increased at sterilization reversal. Coagulation sterilization reversals resulted in the lowest rates of pregnancies and births. Ligation/resection reversals had intermediate success rates. LIMITATIONS, REASONS FOR CAUTION Limitations of our study include probable underreporting of pregnancies based on patient-initiated reports; possible errors in the reporting of pregnancies or early miscarriages that may have been based solely on home pregnancy tests; and probable over

    Ectopic liver (EL) tissue is a rare entity which is reported to occur in several organs such as the gallbladder, pancreas and some other places. The EL tissue is usually detected incidentally during laparoscopy or autopsy, and several potential mechanisms may explain the development of liver ectopia. Although ectopic liver tissue is usually asymptomatic, it develops the same pathologic conditions as orthotopic liver. Although incidental ectopic livers rarely existing and do not have clinical importance, they should be looked for during electron microscope scan and histopathological examination should be carried out to rule out pathological changes since development of hepatocellular carcinoma is a possible issue. In this article, we presented an EL tissue in stomach of which only two cases were reported previously and this is the first reported case of a laparoscopically treated EL which lies to the bottom submucosal of the stomach. It would seem sensible to resect the ectopic tissue under endoscopic and the patient was well when seen for follow-up three months later. PMID:26617914

    Background. The objective of this study was to estimate trends in ectopic pregnancies (EP) in a tertiary care center of Eastern Saudi Arabia. Method. Information about patients with ectopic pregnancies who had been admitted to King Fahd Hospital of the University, AlKhobar, between January 2000 and 31 December 2011 was collected from a computerized hospital registry. Age-specific ectopic pregnancy incidence was calculated. The data was analyzed using SPSS (Statistical Package for the Social Sciences), version 14.0 (Chicago, IL, USA). Results. There were 274 EPs during the study period; the yearly incidence in terms of 24,098 deliveries was 1.19%. The average age was 28.99 Å 5.62 years. During a three-year period (2000–2002), the incidence was 0.92%; from 2003 to 2005, the incidence was 1.01%; from 2006 to 2008, the incidence was 1.51%; and from 2009 to 2011, the incidence was 1.35%. Age-adjusted ectopic pregnancy incidence rates steadily increased from 92.23 per 10,000 women years during the period 2000–2002 to 149.408 during the 2006–2008 period; since then, it has declined to 110.313 per 10,000 women years. Conclusions. Our study reveals that the incidence of EP has decreased from what it had been during the mid-2000s but has remained significantly elevated when compared to the early 2000s.

    To test the hypothesis of a heritable base of ectopic ureters (EU) in Entlebucher Mountain Dogs (EMD) and to elucidate associated risk factors and mode of inheritance of the disease, 565 EMD were clinically investigated and population genetic analyses performed. Based on the location of the most caudal termination of the ureteral openings, 552 EMD were classified into three phenotype groups trigone, intravesically and extravesically ectopic based on results of abdominal sonography, urethra-cystoscopy and/or contrast-enhanced computed tomography. One-third (32.9%) of the phenotyped animals had normal terminations of both ureters in the bladder trigone, 47.3% had at least one intravesicular ectopic termination and 19.8% had at least one extravesicular ectopic termination. Multivariate mixed logistic regression revealed gender as a risk factor associated with EU as males were more often affected than females. Complex segregation analysis indicated a hereditary basis for EU in EMD and the involvement of a major gene in the occurrence of the extravesicular EU phenotype.

    Introduction. The congenital anomalies of breast, especially the polymastia (supernumerary breast) and polythelia (supernumerary nipple), always do not fail to amuse the clinicians because of their varied presentations, associated renal anomalies, and pathologies arising from them. The axillary polymastia is a variant of ectopic breast tissue (EBT). Ectopic breast tissue can undergo the same physiological and pathological processes as the normally located breast. The incidence of fibroadenoma developing in ectopic breast is reported as a rare entity, the most common being the carcinoma. Case Presentation. A 31-year-old Dravidian female presented with a lump of 4 cm in the right axilla for the past year which gradually increased in size, giving discomfort. Our initial differential diagnosis was fibroadenoma, lipoma, and lymphadenopathy. Further investigation and histopathological report of excision biopsy confirmed it as a fibroadenoma on ectopic breast tissue in the axilla. Patient has no associated urological or cardiac anomaly. Conclusion. This case has been reported for its rarity and to reemphasise the importance of screening of EBT for any pathology during routine screening of breast. PMID:23607040

    Heritable ectopic mineralization disorders represent a phenotypically diverse group of conditions characterized by deposition of calcium phosphate complexes in soft connective tissues. The prototype of such conditions is pseudoxanthoma elasticum (PXE), and related conditions with overlapping clinical features include generalized arterial calcification of infancy (GACI) and arterial calcification due to CD73 deficiency (ACDC). Molecular genetic investigations have revealed mutations in the genes physiologically involved in generation of inorganic pyrophosphate (PPi) and phosphate (Pi), and the findings suggest a unifying pathomechanism relating to reduced PPi/Pi ratio. This hypothesis is based on the notion that PPi serves as a powerful inhibitor of mineralization while Pi is a pro-mineralization factor, and an appropriate PPi/Pi ratio is critical for prevention of ectopic mineralization under homeostatic conditions. PXE International, the premiere patient support organization, advocating on behalf of patients and families with PXE, sponsors regular research meetings evaluating the progress in this and related ectopic mineralization disorders. The latest meetings were held in September 2014 in Bethesda, MD and in September 2015 in Budapest, Hungary. This report summarizes the latest progress in research on PXE and related ectopic mineralization disorders, based on presentations and discussions in these meetings, with pharmacologic implications for currently intractable disorders.

    Meningiomas are benign tumors derived from arachnoid cells. Most commonly an intracranial lesion, meningiomas may be found extracranially in various anatomic sites. A 23-yr-old white female presented with left-sided palpable mass located submucosally in the floor of the mouth. CT scan revealed no evidence of mass elsewhere in the head and neck region. Fine-needle aspiration cytology (FNAC) showed loose and cohesive cellular fragments with lobular growth pattern and uniform round or ovoid cells. The diagnosis of low-grade salivary gland neoplasm, not further classified, was made. The tumor was locally excised. The differential diagnoses of an extracranial meningioma and pleomorphic adenoma were discussed at the frozen section. Based on light microscopic, immunohistochemical, and electron microscopic (EM) findings, the final diagnosis of an ectopic meningioma was rendered. Ectopic meningiomas may pose a diagnostic challenge to clinicians and cytopathologists. It is easily forgotten in the list of differential diagnosis at an ectopic site. Primary ectopic meningioma in a region containing salivary gland(s) may mimic benign and low-grade malignant salivary gland tumors in FNAC.

    Our objective is to describe off-label use of methotrexate in ectopic pregnancy treatment using evidence based medicine. The patient group includes all women with a pregnancy outside the usual endometrium, or of unknown location. Method used was a Medline search on ectopic pregnancy managed using methotrexate treatment; evidence synthesis was done based on this current literature analysis. Level of evidence (LE) were given according to the centre for evidence base medicine rules. Grade was proposed for guidelines but no recommendation was possible as misoprostol is off label use for all the indications studied. In the absence of any contraindication, the protocol recommended for medical treatment of ectopic pregnancy is a single intramuscular injection of methotrexate (MTX) at a dosage of 1mg/kg or 50mg/m(2) (Grade A). It can be repeated once at the same dose should the hCG concentration not fall sufficiently. Pretreatment laboratory results must include a complete blood count and kidney and liver function tests (in accordance with its marketing authorization). MTX is an alternative to conservative treatment such as laparoscopic salpingotomy for uncomplicated tubal pregnancy (Grade A) with pretreatment hCG levels≤5000IU/l (Grade B). Expectant management is preferred for hCG levels<1000IU/l or in the process of spontaneous decreasing (Grade B). Intramuscular MTX is also recommended after the failure of surgical salpingotomy (Grade C) or immediately after surgery, if monitoring is not possible. Except in special circumstances, a local insitu ultrasound-guided MTX injection is not recommended for unruptured tubal pregnancies (Grade B). In situ MTX is an option for treating cervical, interstitial, or cesarean-scar pregnancies (Grade C). In pregnancies of unknown location persisting more than 10days in an asymptomatic woman who has an hCG level>2000IU/l, routine MTX treatment is an option.

    Cartilage has poor regenerative capacity. Donor site morbidity and interference with joint homeostasis should be considered when applying the autologous chondrocyte transplantation technique. The use of ectopically produced cartilage, derived from periosteum, might be a novel method to heal cartilage defects. Ectopic cartilage was produced by dissecting a piece of periosteum from the tibia of rabbits. After 14 days the reactive tissue at the dissection site was harvested and a graft was cored out and press-fit implanted in an osteochondral defect in the medial condyle of the femur with or without addition of hyaluronan. After 3 weeks and 3 months the repair reaction was evaluated by histology. Thionine- and collagen type II-stained sections were evaluated for graft viability, ingrowth of the graft, and joint surface repair. Empty defects remained empty 3 weeks after implantation, ectopic cartilage filled the defect to the level of the surrounding cartilage. Histologically, the grafts were viable, consisting mainly of cartilage, and showed a variable pattern of ingrowth. Three months after implantation empty defects with or without hyaluronan were filled primarily with fibrocartilaginous tissue. Defects treated with ectopic cartilage contained mixtures of fibrocartilaginous and hyaline cartilage. Sometimes a tidemark was observed in the new articular cartilage and the orientation of the cells resembled that of healthy articular cartilage. Subchondral bone repair was excellent. The modified O'Driscoll scores for empty defects without and with hyaluronan were 12.7 +/- 6.4 and 15.3 +/- 3.2; for treated defects scores were better (15.4 +/- 3.9 and 18.2 +/- 2.9). In this conceptual study the use of ectopic cartilage derived from periosteum appears to be a promising novel method for joint surface repair in rabbits.

    Acute renal failure due to bilateral ureteral obstruction is a rare complication after appendectomy in children. We report a case of bilateral ureteric obstruction in a 14-year-old boy nine days after surgery for an acute appendicitis. After saline-filling of the urinary bladder, transabdominal ultrasound demonstrated bilateral hydronephrosis of moderate degree. No abscess was found with CT but presence of millimetric stones on both distal ureters was shown, with bilateral calyceal dilatation. Cystoscopy revealed inflammatory changes in the bladder base. Following introduction of bilateral ureteric stents, there was rapid normalisation of urinary output and serum creatinine. PMID:26295001

    Introduction. Cesarean scar pregnancies (CSPs) are one of the rarest forms of ectopic pregnancy. Given their rarity, there is lack of consensus regarding the management and natural course of CSPs. Case. A 37-year-old G10 P3063 female with a history of two prior cesarean deliveries was diagnosed with her second CSP at 6 weeks and 5 days in her tenth pregnancy. The patient underwent vertical hysterotomy, excision of a gestational sac implanted in the cesarean sac, and bilateral salpingectomy via a laparotomy incision. The histopathology report confirmed immature chorionic villi. The patient returned 10 weeks later and was found to be still pregnant. Obstetric ultrasound confirmed a viable fetus of 19 weeks and 4 days of gestational age with a thin endometrium and an anteroposterior and right lateral placenta with multiple placental lakes. The patient ruptured her membranes at 31 weeks of gestation and pelvic MRI revealed an anterior placenta invading the myometrium and extending to the external serosal surface consistent with placenta increta. Following obstetric interventions, a live female infant was delivered by cesarean hysterectomy (because of placenta increta) at 32 weeks of gestation. Conclusion. Development of standardized guidelines for management of CSPs, as well as heightened vigilance for possible complications, is required for proper care and avoidance of potential morbidity and mortality.

    Bilateral ureteral obstruction in children is a rare condition arising from several medical or surgical pictures. It needs to be promptly suspected in order to attempt a quick renal function recovery. In this paper we concentrated on uncommon causes of obstruction, with the aim of giving a summary of such multiple, rare and heterogeneous conditions joint together by the common denominator of sudden bilateral ureteral obstruction, difficult to be suspected at times. Conversely, typical and well-known diseases have been just run over. We considered pediatric cases of ureteral obstruction presenting as bilateral, along with some cases which truly appeared as single-sided, because of their potential bilateral presentation. We performed a review of the literature by a search on PubMed, CrossRef Metadata Search, internet and reference lists of single articles updated to May 2014, with no time limits in the past. Given that we deal with rare conditions, we decided to include also papers in non-English languages, published with an English abstract. For the sake of clearness, we divided our research results into 8 categories: (1) urolithiasis; (2) congenital urinary tract malformations; (3) immuno-rheumatologic causes of ureteral obstruction; (4) ureteral localization of infections; (5) other systemic infective causes of ureteral obstructions; (6) neoplastic intrinsic ureteral obstructions; (7) extrinsic ureteral obstructions; and (8) iatrogenic trigonal obstruction or inflammation. Of course, different pathogenic mechanisms underlay those clinical pictures, partly well-known and partly not completely understood. PMID:25374811

  10. Multiresolution Bilateral Filtering for Image Denoising

    2008-01-01

    The bilateral filter is a nonlinear filter that does spatial averaging without smoothing edges; it has shown to be an effective image denoising technique. An important issue with the application of the bilateral filter is the selection of the filter parameters, which affect the results significantly. There are two main contributions of this paper. The first contribution is an empirical study of the optimal bilateral filter parameter selection in image denoising applications. The second contribution is an extension of the bilateral filter: multiresolution bilateral filter, where bilateral filtering is applied to the approximation (low-frequency) subbands of a signal decomposed using a wavelet filter bank. The multiresolution bilateral filter is combined with wavelet thresholding to form a new image denoising framework, which turns out to be very effective in eliminating noise in real noisy images. Experimental results with both simulated and real data are provided. PMID:19004705

    Tetrahymena is a useful eukaryotic model for biochemistry and molecular cell biology studies. We previously demonstrated that targeted ectopic DNA elimination, also called co-Deletion (coDel), can be induced by the introduction of an internal eliminated sequence (IES)-target DNA chimeric construct. In this study, we demonstrate that coDel occurs at most of the loci tested and can be used for the production of somatic gene KO strains. We also showed that coDel at two loci can be simultaneously induced by a single transformation; thus, coDel can be used to disrupt multiple gene loci in a single cell. Therefore, coDel is a useful tool for functional genetics in Tetrahymena and further extends the usefulness of this model organism.

    Background To report the first series of video-assisted thoracoscopic surgery (VATS) resection of mediastinal ectopic parathyroid adenomas (MEPAs) in the UK. Methods A case series of seven cases undergoing VATS between 2004 and 2009 to treat single gland hyperparathyroidism. Methylene blue (MB) was used in 5/7 cases immediately before exploration to identify the adenomas. Carbon dioxide (CO2) up to pressures of 10 mmHg was used safely to deflate the lung in two cases. Results There were five women and two men with a mean age of 53 years (range, 27-72 years). Histopathology confirmed successful resection of the parathyroid adenoma in 6/7 cases. There was one conversion to open thoracotomy due to bleeding from the azygos vein resulting from excessive traction. Despite marked MB uptake, this patient proved to have tuberculoid adenopathy and no parathyroid tissue was identified. Postoperative plasma calcium returned to normal in 6/7 patients and parathyroid hormone (PTH) level in 6/7 patients. The median hospital stay was 2 days and there was no mortality in this series. Conclusions MEPAs can be safely resected using VATS with minimal surgical morbidity, short drainage time and short hospital stay. CO2 insufflation and the intraoperative use of MB are safe and help to accurately localise the ectopic adenoma. VATS should be considered as the first-line approach for resection of MEPAs.

    Hair graying in mouse is attributed to the loss of melanocyte stem cell function and the progressive depletion of the follicular melanocyte population. Single-gene, hair graying mouse models have pointed to a number of critical pathways involved in melanocyte stem cell biology; however, the broad range of phenotypic variation observed in human hair graying suggests that additional genetic variants involved in this process may yet be discovered. Using a sensitized approach, we ask here whether natural genetic variation influences a predominant cellular mechanism of hair graying in mouse, melanocyte stem cell differentiation. We developed an innovative method to quantify melanocyte stem cell differentiation by measuring ectopically pigmented melanocyte stem cells in response to the melanocyte-specific transgene Tg(Dct-Sox10). We make the novel observation that the production of ectopically pigmented melanocyte stem cells varies considerably across strains. The success of sensitizing for melanocyte stem cell differentiation by Tg(Dct-Sox10) sets the stage for future investigations into the genetic basis of strain-specific contributions to melanocyte stem cell biology.

    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.

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    Ectopic liver is a rare developmental abnormality. It is often asymptomatic and could be determined during the surgery. AIthough it could be detected in different areas of the body either below or above of the diaphragm, ectopic liver is usually found on the wall of the gallbladder. The importance of the ectopic liver came from the elevated risk of development of hepatocellulary carcinoma from ectopic tissue. Ectopic liver tissue could also mimic malign masses in radiographic studies. Ultrasound-guided percutaneous biopsies could be helpful for preoperative diagnosis. Recently, widespread usage of laparoscopic techniques caused an increase on the description of ectopic liver tissues located on the gallbladder. Due to the potential risk of developing malignancy the resection of the mass should be the preferred approach for an incidentally or intraoperatively diagnosed ectopic liver tissue.

    Congenital bilateral vocal cord paralysis (CBVCP) is a rare but potentially life-threatening condition and awareness of the condition is necessary to ensure early diagnosis and treatment. This case describes a 25-month-old boy suffering from CBVCP. The main symptoms at birth were inspiratory stridor combined with a normal voice and feeding problems. The difficulties in achieving the right diagnosis are demonstrated, and the treatment so far, including tracheotomy and a feeding tube, is outlined. The importance of fibre optic laryngoscopy in both diagnosis and control is stressed. PMID:19174021

    Independent bilateral primary bronchial carcinomas are not common. Since Beyreuther's description in 1924, 16 well-documented cases of independent primary bronchial carcinomas of different histology have been described. From 1965 to 1970, eight cases were seen at the London Chest Hospital. In order to make the diagnosis of a second primary bronchial carcinoma, each tumour should be malignant and neither should be a metastasis from the other. To meet this last criterion, the histopathological features of the two tumours must be different. Many cases have been described in the literature as double primary bronchial carcinomas where the second primary had the same histological features as the first. Images PMID:4327711

The Magnetic Resonance Image of the pituitary gland revealed a microadenoma without extension in the cavernous sinus and a partial empty sella. The computed tomography scan showed a discreet bilateral adrenal hyperplasia with a left nodule (23 mm in diameter) a second nodule was noted. These data suggested the eventuality of maconodular adrenocortical hyperplasia in long-standing Cushing's disease. We discuss the implications of this finding for diagnosis, treatment and follow-up.

    The purpose of this study was to determine the reliability of 1 repetition maximum (1RM) split squat (SS) and establish the efficacy of collecting 1RM-SS and 1RM bilateral squat (BLS) data in the same session, for a non-resistance-trained recreationally active population. Fourteen males performed a submaximal familiarization session and 5 testing sessions. After familiarization, the 1RM-SS was tested in the following 3 sessions. In session 4, subjects were tested in both 1RM-SS and 1RM-BLS, with half performing SS then BLS and the remainder BLS then SS. In session 5, the testing order was reversed. Reliability statistics calculated included the following: changes in mean across sessions, coefficient of variation calculated from the typical error (TE) scores (%CV(TE)), and test-retest reliability (intraclass correlation coefficient [ICC]) of 1RM-SS. Statistically significant differences between the mean 1RM-SS in sessions 1 and 2 (2.14 kg, p = 0.001), and sessions 1 and 3 (2.86 kg, p < 0.003) were found, indicating the requirement for an additional familiarization session before 1RM-SS data collection. The %CV(TE) was 2.53% and the ICC was 0.97 for the 1RM-SS protocol. Performing SS before BLS tended to increase the mean 1RM-BLS (+2.1%), although the difference was not significant (p = 0.055). A reliable measure of 1RM-SS can be determined after 1 submaximal and 1 maximal familiarization session in non-resistance-trained recreationally active men. Analysis of the current data suggests that it is appropriate to perform both 1RM-SS and 1RM-BLS tests within the same testing session if 1RM-SS is performed before 1RM-BLS. However, further testing is warranted to firmly establish the effects of 1RM-SS on subsequent 1RM-BLS.

    A 30-year-old Caucasian man presented with severe Cushing's syndrome (CS) resulting from ectopic adrenocorticotropin syndrome (EAS) from a metastatic pancreatic neuroendocrine tumor. The patient remained hypercortisolemic despite treatment with steroidogenesis inhibitors, chemotherapy, and octreotide long-acting release (LAR) and was enrolled in a 24-week, phase 3 clinical trial of mifepristone for inoperable hypercortisolemia. After mifepristone was added to ongoing octreotide LAR treatment, EAS symptoms essentially resolved. Cortisol decreased dramatically, despite mifepristone's competitive glucocorticoid receptor antagonist effects. The clinical and biochemical effects reversed upon mifepristone discontinuation despite the continued use of octreotide LAR therapy. Substantial improvement in octreotide LAR efficacy with mifepristone use was noted in this patient with ectopic CS, consistent with upregulation of somatostatin receptors previously downregulated by hypercortisolemia.

    Correction of Class II relationship, deep bite and ectopically erupting canines is an orthodontic challenge for the clinician. A 13-year-old male patient presented with Class II malocclusion, ectopically erupting canines, and cross bite with maxillary left lateral incisor. He was treated with a combination of Headgear, Forsus™ fatigue resistant device [FFRD] with fixed mechanotherapy for the management of space deficiency and correction of Class II malocclusions. Headgear was used to distalize upper first molars and also to prevent further downward and forward growth of the maxilla. Then Forsus™ FFRD was used for the advancement of the mandible. The molar and canine relationship were corrected from a Class II to a Class I. The objectives were to establish good occlusion and enable eruption of unerupted canines. All these objectives were achieved and remained stable. PMID:26097371

    Location of ectopic tooth in a nondentate area like the maxillary antrum is rare. A 17-year-old boy, with one year history of recurrent right facial swelling and radiographic finding of a maxillary third molar tooth located at the posterior wall of the maxillary antrum, is presented. Under endotracheal intubation, the tooth was extracted through a Caldwell-Luc antrostomy approach and patient had an uneventful recovery and has been symptom free for eight months. Ectopic tooth in the maxillary antrum is rare and is commonest with maxillary third molar. It may be symptomless but is more commonly associated with inflammatory symptoms. The treatment of choice is surgical excision which is mostly carried out with Caldwell-Luc approach, even though endoscopic approach is being reported. PMID:25132999

    This case is of a 39-year-old Filipino woman who within 2 months developed, Cushing's features she had no known comorbidities and no history of steroid intake. The patient also presented with hyperpigmentation of knuckles and toes, metabolic alkalosis and persistent hypokalaemia noted as proximal muscle weakness. The patient was referred to our institution for acutely worsening behavioural and psychiatric changes. Work-up for endogenous Cushing's syndrome revealed a significant adrenocorticotropic hormone production from an ectopic source. Further imaging was requested to locate the tumour, but the patient eventually succumbed to the drastic complications of hypercortisolism. On autopsy, the patient was found to have an ectopic well-differentiated neuroendocrine tumour located at the pancreatic head with metastasis to the right hepatic lobe. PMID:23861274

    After successful cochlear implantation in one ear, some patients continue to use a hearing aid at the contralateral ear. They report an improved reception of speech, especially in noise, as well as a better perception of music when the hearing aid and cochlear implant are used in this bimodal combination. Some individuals in this bimodal patient group also report the impression of an improved localization ability. Similar experiences are reported by the group of bilateral cochlear implantees. In this study, a survey of 11 bimodally and 4 bilaterally equipped cochlear implant users was carried out to assess localization ability. Individuals in the bimodal implant group were all provided with the same type of hearing aid in the opposite ear, and subjects in the bilateral implant group used cochlear implants of the same manufacturer on each ear. Subjects adjusted the spot of a computer-controlled laser-pointer to the perceived direction of sound incidence in the frontal horizontal plane by rotating a trackball. Two subjects of the bimodal group who had substantial residual hearing showed localization ability in the bimodal configuration, whereas using each single device only the subject with better residual hearing was able to discriminate the side of sound origin. Five other subjects with more pronounced hearing loss displayed an ability for side discrimination through the use of bimodal aids, while four of them were already able to discriminate the side with a single device. Of the bilateral cochlear implant group one subject showed localization accuracy close to that of normal hearing subjects. This subject was also able to discriminate the side of sound origin using the first implanted device alone. The other three bilaterally equipped subjects showed limited localization ability using both devices. Among them one subject demonstrated a side-discrimination ability using only the first implanted device.

    A 34-year-old woman was diagnosed by ultrasound with a six-week ectopic pregnancy with implantation of the gestational sac in the bladder wall. She was initially treated with methotrexate 50 mg/m(2) i.m. Although a 22% reduction in the levels of beta-hCG was observed at first, there was a rupture of gestational sac. The patient underwent an emergency laparotomy with a resulting partial cystectomy, and made an uneventful recovery.

    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.

    Cross-fused renal ectopia is a rare congenital anomaly in which both kidneys are fused and located on the same side. We report a case of right-to-left cross-fused renal ectopia and nephrolithiasis, in whom retrograde intrarenal surgery was used to treat the stone disease. To our knowledge, this is the first case of retrograde intrarenal surgery of a crossed-fused ectopic kidney. PMID:25481231

  11. Bilateral internal thoracic artery grafting

    PubMed Central

    2013-01-01

    The effectiveness of the left internal mammary artery graft to the anterior descending coronary artery as a surgical strategy has been shown to improve the survival rate and decrease the risk of adverse cardiac events in patients undergoing coronary bypass surgery. These clinical benefits appear to be related to the superior short and long-term patency rates of the internal thoracic artery graft. Although the advantages of using of both internal thoracic arteries (ITA) for bypass grafting have taken longer to prove, recent results from multiple data sets now support these findings. The major advantage of bilateral ITA grafting appears to be improved survival rate, while the disadvantages of complex ITA grafting include the increased complexity of operation, and an increased risk of wound complications. While these short-term disadvantages have been mitigated in contemporary surgical practice, they have not eliminated. Bilateral ITA grafting should be considered the procedure of choice for patients undergoing coronary bypass surgery that have a predicted survival rate of longer than ten years. PMID:23977627

    A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available. PMID:11353349

    Ectopic lacrimal gland, being one of the choristomas, is comprised of lacrimal gland tissue outside the lacrimal gland fossa in the fronto-lateral part of the orbital roof. Ectopic lacrimal gland is a rare condition where the gland may be found in the orbit, eyelids, ocular adnexa or within the globe. Neoplastic transformation of such tissue may occur. A sixty-two-year old male patient presented with right eye proptosis and slight nasal displacement of the globe. Computerized tomography scan revealed a well-defined hypodense lesion of size 19 x 18 x 20 mm supero-lateral to lateral rectus muscle, with mild proptosis and thinning of the right lateral orbital wall. Excisional biopsy was performed through a lateral orbitotomy approach. A well circumscribed globular mass was removed from the right orbit, well behind the fossa for the lacrimal gland in the retrobulbar space. Histopathology was suggestive of pleomorphic adenoma of lacrimal gland. Pleomorphic adenoma is an epithelial tumor of the lacrimal gland which is extremely rare from an ectopic lacrimal gland and only few cases have been reported in literature till date.

  14. The ectopic pregnancy, a diagnostic and therapeutic challenge

    2008-01-01

    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 mind. The individual risk factors may be cumulative, particularly with a previous history of extrauterine pregnancy or tubal surgery (including sterilisations), pelvic post–inflammatory status (adhesions proved by coelioscopy) or presence of an intrauterine device. Diagnosis is based on serum beta–hCG concentration and transvaginal ultrasound Laparoscopy is the treatment of choice for tubal pregnancies. The decision to perform salpingotomy depends on the presence/status of a contra lateral tube. In carefully selected cases local or intra–muscular administration of methotrexate allows conservative treatment, provided the patient does not present acute bleeding. It is also indicated where trophoblastic tissue persists after surgery, notably salpingostomy, and in non–tubal ectopic pregnancies. The latter are rare, however, and it is important to recognise them in view of the more serious complications. PMID:20108478

    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.

    A 45-year-old man of bilateral occipital infarction with central homonymous hemianopia is reported. He was admitted to our hospital with complaints of visual loss and large central scotoma on both eyes. Pupillary light reaction and ocular fundi were normal. On admission, bilateral retrobulbar optic neuritis was suspected. However, congruous, irregular central scotomas with vertical step were observed in both eyes with Goldmann perimetry. X-ray computed tomography (CT) and magnetic resonance imaging (MRI) revealed the infarction in bilateral occipital tips. Bilateral central homonymous hemianopia is considered to be rare and a case in which occipital lobe lesions were detected with X-ray CT and MRI has not been reported. We stress that bilateral central scotomas with vertical step indicate bilateral occipital lesions.

    Ectopic anterior mediastinal parathyroid adenoma is a rare cause of Primary Hyperparathyroidism (PHPT). Imaging studies such as Technetium-99m (99mTc) sestamibi parathyroid scan along with a Single Photon Emission Computerized Tomogram (SPECT), and contrast enhanced Computerized Tomogram (CT) of the neck and thorax can precisely localize the ectopic mediastinal parathyroid adenoma. We report a 40-year-old gentleman who presented with persistent pain in the right shoulder following trivial trauma. His biochemical investigations showed an elevated serum calcium of 11.6mg% (Normal: 8.3-10.4 mg%) along with an elevated iPTH of 1443 pg/ml (normal: 8-70 pg/ml) which were suggestive of primary hyperparathyroidism. The localization studies revealed an ectopic cystic parathyroid adenoma in the anterior mediastinum that was not accessible from the neck. He underwent a Video Assisted Thoracoscopic (VAT) excision procedure with normalization of serum calcium and an uncomplicated recovery. The VAT approach is a successful minimally invasive technique for mediastinal parathyroidectomy. PMID:27504353

We present a case of a 69-year-old bilateral below-knee amputee male admitted to the emergency department with bilateral hip pain and radiological evidence of bilateral displaced neck of femur fractures. The patient subsequently underwent synchronous bilateral total hip replacements under general anaesthetic and an epidural and then went on to make a full recovery. He was discharged 27 days after arrival in hospital. Outpatient follow-up at 3 months has shown that the patient has returned to a similar level of preinjury function and is still able to carry out his daily activities with walking aids and bilateral leg prostheses.

    Cell-based therapy has been viewed as a promising alternative to organ transplantation, but cell transplantation aimed at organ repair is not always possible. Here, we show that the mouse lymph node can support the engraftment and growth of healthy cells from multiple tissues. Direct injection of hepatocytes into a single mouse lymph node generated enough ectopic liver mass to rescue survival of mice with lethal metabolic disease. Furthermore, thymuses transplanted into a lymph node of athymic nude mice generate a functional immune system capable of rejecting allogeneic and xenogeneic grafts. Finally, pancreatic islets injected into the lymph node of diabetic mice restore normal glucose control. Collectively, these results suggest the practical approach of targeting lymph nodes to restore, maintain or improve tissue and organ functions. PMID:23000933

    Summary: A successful bilateral ear composite graft nonmicrosurgical reattachment is presented. In cases where suitable vessels are unavailable for microsurgical revascularization, the reconstructive challenge can be formidable for salvaging the unique anatomic and aesthetic structure of the ear. The case is presented of an 18-year-old woman who was a victim of an assault wherein both of her ears were intentionally amputated by her attacker. She underwent successful surgical reattachment followed by a postoperative regimen of hyperbaric oxygen, cooling, and meticulous wound care. The patient achieved 100% survival of her left ear graft and 95% survival of her right ear graft. Clinical photographs at 18 months are presented, along with a discussion of the possible implications for other reconstructive applications. PMID:25289367

    Dentigerous cysts are common odontogenic cysts that are associated with the crown of the tooth and typically develop from single lesions. Bilateral and multiple dentigerous cysts are very rare and occur in patients with syndromic conditions. This paper presents a case report of a 15-year-old male patient that experienced non-syndromic bilateral dentigerous cysts that simultaneously occurred in all four dental quadrants around the unerupted third molars. Clinicians should confirm the extent of cystic lesions using a panoramic view and computed tomography, and should keep the possibility of bilateral dentigerous cysts in mind as a potential diagnosis, even in a non-syndromic patient.

Multiple bilateral renal stones were awlso demonstrated in the imaging studies. The ureteral stones ranged from 7 to 23 mm in length and 5-11 mm in width. Ureteroscopy and holmium laser lithotripsy for the ureteral stones were done sequentially in the four ureteral limbs, in a single session. Four double-J stents were inserted after removal of all ureteric stones, one in each ureter. The patient passed uneventful postoperative course. The patient has received extracorporeal shock wave lithotripsy sessions for the bilateral renal stones. The double-J stents were removed under local anesthesia after clearance of all stones. To the best of our knowledge, there are no data in the literature representing an identical case. PMID:27141198

    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.

    Bilateral adrenal hemorrhage with subsequent adrenal insufficiency is a recognized complication of anticoagulant therapy. Because the clinical manifestations are often nonspecific, the antemortem diagnosis of adrenal hemorrhage has been a difficult clinical problem. Computed tomography (CT) provides detailed images of the adrenal glands that are not possible with conventional imaging methods. The CT findings of bilateral adrenal hemorrhage in an anticoagulated patient are reported.

    Portal hypertension frequently causes the appearance of porto-systemic shunts, such as esophageal varices and also, but with much less frequency, other atypical shunts known as ectopic varices. Despite their infrequency/rarity, ectopic varices can cause serious gastrointestinal bleeding. Intraabdominal adhesions, especially post-operative ones, promote their appearance. The therapeutic management of ectopic varices is initially the same as that for esophageal varices but surgical treatment is usually necessary as a diagnostic and therapeutic procedure.

    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.

  16. Contemporary Concepts for the Bilateral Cleft Lip and Nasal Repair

    2012-01-01

    The bilateral cleft lip and nasal deformity presents a complex challenge for repair. Surgical techniques continue to evolve and are focused on primary anatomic realignment of the tissues. This can be accomplished in a single-stage or two-stage repair early in infancy to provide a foundation for future growth of the lip and nasal tissue. Most cleft surgeons currently perform a single-stage repair for simplifying patient care. Certain institutions utilize presurgical orthopedics for alignment of the maxillary segments and nasal shaping. Methods for the bilateral cleft lip repair are combined with various open and closed rhinoplasty techniques to achieve improved correction of the primary nasal deformity. There is recent focus on shaping the nose for columellar and tip support, as well as alar contour and alar base position. The authors will present a new technique for closure of the nasal floor to prevent the alveolar cleft fistula. Although the alveolar fistula is closed, alveolar bone grafting is still required at the usual time in dental development to fuse the maxilla. It is paramount to try and minimize the stigmata of secondary deformities that historically have been characteristic of the repaired bilateral cleft lip. A properly planned and executed repair reduces the number of revisions and can spare a child from living with secondary deformities. PMID:24179448

    Ectopic thyroid is a rare embryogenic anomaly that occurs during its migration from foramen caecum to its pretracheal position. An intracardiac ectopic location is even rarer and found most commonly in the right ventricular outflow tract in sporadic reports. While surgery in symptomatic patients seems appropriate, resection of non-neoplastic ectopic tissue remains a clinical equipoise. Its occurrence is often unsuspected by clinicians, but its possibility should be considered due to its typical location in the right ventricular outflow tract. Unlike true neoplastic intracardiac tumour which mandates surgical resection, both surgical and non-surgical approach may be considered for an intracardiac ectopic thyroid mass. PMID:23912623

    Martínez, Arturo; Alcaraz, Raúl; Rieta, José J

    2011-01-01

    Ectopic beats are early heart beats with remarkable large amplitude that provoke serious disturbances in the analysis of electrocardiograms (ECG). These beats are very common in atrial fibrillation (AF) and are the source of important residua when the QRST is intended to be removed. Given that QRST cancellation is a binding step in the appropriate analysis of atrial activity (AA) in AF, a method for ventricular ectopic beats cancellation is proposed as a previous step to the application of any QRST removal technique. First, the method discriminates between normal and ectopic beats with an accuracy higher than 99% through QRS morphological characterization. Next, the most similar ectopic beats to the one under cancellation are clustered and serve to get their eigenvector matrix by principal component analysis. Finally, the highest variance eigenvector is used as cancellation template. The reduction ectopic rate (RER) has been defined to evaluate the method's performance by using templates generated with 5, 10, 20, 40 or 80 ectopics. Optimal results were reached with the 5 most similar complexes, yielding a RER higher than 5.5. In addition, a decreasing RER trend was noticed as the number of considered ectopics for cancellation increased. As conclusion, given that ectopics presented a remarkable variability in their morphology, the proposed cancellation approach is a robust ectopic remover and can notably facilitate the later application of any QRST cancellation technique to extract the AA in the best conditions.

    We report a case of a rare tumor of the head and neck: ectopic hamartomatous thymoma. The tumor involved the sus-clavicular area of a 48 year-old male. Ectopic hamartomatous thymoma exclusively occurs in the sus-scapular region. Histologically, it is characterized by the association of spindle-cell fascicles, epithelial solid or cystic structures and foci of mature adipose tIssue. Spindle cells express diffusely cytokeratins. The differential diagnosis of ectopic hamartomatous thymoma includes mixed tumor of salivary glands, biphasic synovial sarcoma and sarcomatoid carcinoma. Ectopic hamartomatous thymoma is a benign tumor which does not recur after complete excision.

    The dilated odontoma is an infrequent developmental alteration that appears in any area of the dental arches and can affect deciduous, permanent and supernumerary tooth. Dens invaginatus is a developmental anomaly resulting from invagination of a portion of crown forming within the enamel organ during odontogenesis. The most extreme form of dens invaginatus is known as dilated odontoma. The aim of this case report is to present a rare case of bilateral dilated odontoma affecting a microdontic permanent lateral incisor in a 30 year old female patient with hypodontia and peglateral teeth with its clinical, radiological and histological features, which has yet been not reported. Bilateral presence of dilated odontoma is not a common occurrence, although a single tooth involvement in each case has been reported in the literature.

    Ectopic pregnancy is the most life threatening emergency in pregnancy. Increase in incidence and impairment in fertility are now the real concerns. The aim of this study was to estimate the epidemiological, diagnostic and therapeutic aspects of ectopic pregnancy with a view to suggest action to improve the prognosis. This was a prospective study carried out at NRS Medical College, Kolkata, among consecutive 180 patients of ectopic pregnancy admitted from January, 2002 to December, 2004. During this period the incidence of ectopic pregnancy was 1 in 161(0.6%). The peak age of incidence was 26-30 years; primi were the most sufferers. There were 65.0% patients was had identifiable risk factors. Tubectomy (14.4%), history of abortion (26.1%), infertility (12.2%), pelvic inflammatory diseases (12.8%) and history of previous surgery (11.1%) were the important risk factors. Amenorrhoea (76.1%), abdominal pain (86.1%) and vaginal bleeding (42.2%) were the frequent presenting complaints. There were 87.8% patients was had pallor, 9.4% were admitted with features of shock. Cervical motion tenderness (82.2%) was the most frequent sign. Urinary beta-hCG was positive in 96.1% cases. Ultrasonography revealed diagnosis in 2/3rds cases among 129 patients. Culdocentesis evoked the diagnosis in 73.3% cases out of 135 patients. In 95.0% cases it was of tubal variety, 70.2% ruptured, 19.9% tubal abortion and 9.9% unruptured. Surgery by open method in the form of salpingectomy (81.9%), salpingo-oophorectomy (9.3%) and salpingostomy (5.3%) were the mainstay of management. Expectant management and medical therapy can be offered only in 1.2% and 1.75% respectively. There was no case fatality. By reducing and identifying the risk factors and 'catching' the patients at the earliest it is possible to improve the prognosis so far as morbidity, mortality and fertility are concerned.

    In the early 1980s, we analyzed the metabolic profile of 930 men and women and concluded that an abdominal distribution of fat for a given BMI is associated with increased insulin resistance and risk of developing type 2 diabetes and cardiovascular disease. The correlation between abdominal fat and metabolic dysfunction has since been validated in many studies, and waist circumference is now a criterion for the diagnosis of metabolic syndrome. Several mechanisms for this relationship have been postulated; however, we now know that visceral fat is only one of many ectopic fat depots used when the subcutaneous adipose tissue cannot accommodate excess fat because of its limited expandability.

The pathology usually presents itself commonly in mandible and less commonly in maxilla. The occurrence of KCOT in maxillary sinus is reported as rare and multiple occurrences are mostly associated along with the presence of Nevoid Basal Cell Carcinoma (NBCC) syndrome. Here, we present a rare case of bilateral Maxillary OKC involving maxillary sinuses, without the presence of NBCC syndrome. An interesting feature of this case is the presence of left upper third molar in ectopic position in maxillary sinus and a vertically impacted right third molar suggesting an origin from the dental lamina.

    The first retroperitoneal lumbar sympathectomy was performed in 1924 by Julio Diez. The classic procedure for sympathectomy is open surgery. We report a unilateral laparoscopic retroperitoneal approach to perform bilateral lumbar sympathectomy. This approach was performed for a 43-year-old man with distal arterial occlusive disease and no indication for direct revascularization. His predominant symptoms were intermittent claudication at 100 metres and cold legs. The patient was placed in a left lateral decubitus position. The optical system was placed first in an intra-abdominal position to check that the trocars were well positioned in the retroperitoneal space. The dissection of retroperitoneum was performed by CO2 insufflation. The inferior vena cava was reclined and the right sympathetic chain was individualized. Two ganglia (L3-L4) were removed by bipolar electro-coagulation. The aorta was isolated on a vessel loop and careful anterior traction allowed a retro-aortic pre-vertebral approach between the lumbar vessels. The left sympathetic chain was dissected. Two ganglia (L3-L4) were removed by bipolar electro-coagulation. PMID:17685269

    There are three main highland areas on Venus: Beta Regio, Ishtar Terra and Aphrodite Terra. The latter is least known and the least mapped, yet existing analyses of Aphrodite Terra based on available Pioneer-Venus orbiter data suggest that it may be the site of extensive rifting. Some of the highest resolution (30 km) PV data (SAR) included most of the western half of Aphrodite Terra. Recent analysis of the SAR data together with Arecibo range-doppler topographic profiling (10 X 100 km horizontal and 10 m vertical resolution) across parts of Aphrodite, further characterized the nature of possible tectonic processes in the equatorial highlands. The existence of distinct topographic and radar morphologic linear discontinuities across the nearly east-west strike of Aphrodite Terra is indicated. Another prominent set of linear features is distinctly parallel to and orthogonal to the ground tracks of the PV spacecraft and are not included because of the possibility that they are artifacts. Study of the northwest trending cross-strike discontinuities (CSD's) and the nature of topographic and morphologic features along their strike suggest the presence of bilateral topographic and morphologic symmetry about the long axis of Aphrodite Terra.

    A nineteen years old woman with ambiguous external genitalia was studied. This condition had been previously identified as a newborn, but her parents refused medical attention and it was reared as a girl. At 12-years, she began spontaneous mammary development, appearing pubic and axillary hair, and clitoral enlargement. The menarche occurred at 15-years and it was followed by irregular periods. Physical examination, showed absence of hirsutism and acne, normal mammary development equivalent to grade V of Tanner. The external genitalia showed fused labio-scrotal folds with an small introitus. The urethral meatus was absent and was later located inside the introitus. There was a big phallus similar to an adult penis with a normal glans, flexed by a chordee. Hormonal determinations discarded congenital adrenal hyperplasia. The karyotype was 46,XX and testosterone levels were in adult male range. Pelvic ultrasonography disclosed a normal uterus and both gonads in confirmed by laparoscopy identifying bilateral ovotestis. Testicular tissue was removed and plastic reconstruction of female genitals was done. PMID:9528217

    Among complications in orthognathic surgery, the insurgence of pneumothorax is very rare. Pneumothorax is the presence of air or gas in the pleural cavity and it is rare complications in the postoperative oral and maxillofacial surgery patient. The clinical results are dependent on the degree of collapse of the lung on the affected side. Pneumothorax can impair oxygenation and/or ventilation. If the pneumothorax is significant, it can cause a shift of the mediastinum and compromise haemodynamic stability. While 10% of pneumothoraces are asymptomatic, patients often complain of acute chest pain and difficulty breathing. There is a reduction in vital capacity, tachycardia, tachypnoea and a decrease in partial pressure of oxygen with an inability to maintain oxygen saturations. We observed this unusual surgical consequence in a 28-year-old female with negative clinical history and instrumental evaluation after Le Fort I osteotomy and bilateral sagittal split osteotomy (BSSO). No further consequences, no neurological sequelae, no infections and no other osteotomies sequelae were seen. Sudden post-surgical dispnea associated to sub-cutaneous emphysema of the neck and of the thorax must be adequately observed with the aim of monitoring further severe sequelae. The anaesthetic management of the emergency difficult airway in any post-surgical orthognatic treatment can be extremely difficult requiring a multi-disciplinary approach. PMID:23814593

    Functional sensory and motor areas in the developing mammalian neocortex are formed through a complex interaction of cortically intrinsic mechanisms, such as gene expression, and cortically extrinsic mechanisms such as those mediated by thalamic input from the senses. Both intrinsic and extrinsic mechanisms are believed to be involved in cortical patterning and the establishment of areal boundaries in early development; however, the nature of the interaction between intrinsic and extrinsic processes is not well understood. In a previous study, we used a perinatal bilateral enucleation mouse model to test some aspects of this interaction by reweighting sensory input to the developing cortex. Visual deprivation at birth resulted in a shift of intraneocortical connections (INCs) that aligned with ectopic ephrin A5 expression in the same location ten days later at postnatal day (P) 10. A prevailing question remained: Does visual deprivation first induce a change in gene expression, followed by a shift in INCs, or vice versa? In the present study, we address this question by investigating the neuroanatomy and patterns of gene expression in post-natal day (P) 1 and 4 mice following bilateral enucleation at birth. Our results demonstrate a rapid reduction in dorsal lateral geniculate nucleus (dLGN) size and ephrin A5 gene expression 24-hours post-enucleation, with more profound effects apparent at P4. The reduced nuclear size and diminished gene expression mirrors subtle changes in ephrin A5 expression evident in P1 and P4 enucleated neocortex, 11 and 8 days prior to natural eye opening, respectively. Somatosensory and visual INCs were indistinguishable between P1 and P4 mice bilaterally enucleated at birth, indicating that perinatal bilateral enucleation initiates a rapid change in gene expression (within one day) followed by an alteration of sensory INCs later on (second postnatal week). With these results, we gain a deeper understanding of how gene expression and

    Primary adrenal myelolipoma is a rare, non-functioning adrenal benign tumor that is composed of mature adipose tissue and a variable amount of haemopoietic elements. Clinically, it is difficult to get diagnosed with adrenal myelolipoma because the patient usually doesn’t have obvious symptoms and signs in early stage. In the present study, two cases of primary bilateral adrenal myelolipomas are reported. Clinical presentation, imaging diagnostic features, histopathological changes and surgical treatments of the two patients are discussed. Preoperative diagnostic imaging examinations (B-mode ultrasonography, computed tomography and magnetic resonance imaging sans) assisted getting a prediction diagnosis of bilateral adrenal myelolipomas. A two-stage surgery was used to successfully excise bilateral adrenal myelolipomas in the two patients. Conventional open adrenalectomy was applied to remove the adrenal myelolipomas greater than 6 cm, and laparoscopic adrenalectomy was performed to excise the adrenal tumors smaller than 6 cm. Bilateral adrenal myelolipomas of the two patients were finally confirmed by postoperative histopathological examinations. Understanding clinical, imaging diagnostic and histopathological features of bilateral adrenal myelolipomas will facilitate timely diagnosis and treatment of this condition. Surgical removal of bilateral adrenal myelolipomas is safe, curative and beneficial. The two-stage surgery appears to be the best treatment option for the patients with bilateral adrenal myelolipomas because it achieves optimal treatment effectiveness with minimized sequelae.

    Many retinal dystrophies result in photoreceptor loss, but the inner retinal neurons can survive, making them potentially amenable to emerging optogenetic therapies. Here, we show that ectopically expressed human rod opsin, driven by either a non-selective or ON-bipolar cell-specific promoter, can function outside native photoreceptors and restore visual function in a mouse model of advanced retinal degeneration. Electrophysiological recordings from retinal explants and the visual thalamus revealed changes in firing (increases and decreases) induced by simple light pulses, luminance increases, and naturalistic movies in treated mice. These responses could be elicited at light intensities within the physiological range and substantially below those required by other optogenetic strategies. Mice with rod opsin expression driven by the ON-bipolar specific promoter displayed behavioral responses to increases in luminance, flicker, coarse spatial patterns, and elements of a natural movie at levels of contrast and illuminance (≈50-100 lux) typical of natural indoor environments. These data reveal that virally mediated ectopic expression of human rod opsin can restore vision under natural viewing conditions and at moderate light intensities. Given the inherent advantages in employing a human protein, the simplicity of this intervention, and the quality of vision restored, we suggest that rod opsin merits consideration as an optogenetic actuator for treating patients with advanced retinal degeneration.

    Variations regarding the location of an ectopic tooth in the human nasal cavity, although rare, are documented in the literature, but presence of an ectopic tooth on the inferior nasal concha (INC) has not been reported. We observed an anomalous tooth projecting from the posterior margin of the right INC in two adult female skulls. A small quadrangular tooth projected beyond the posterior margin of the hard palate in one of the skulls and a medium sized conical tooth was observed in the other skull. The affected INC in both skulls were located more inferiorly compared to the opposite side and were in close approximation with the hard palate. No similar findings were noted on the contralateral side nor were there any associated congenital or iatrogenic deformity. The phylogenetic, ontogenetic, and clinical importance of this variant is described. Knowledge of such an anomaly is of paramount importance to otorhinolaryngologists, reconstructive and dental surgeons, and radiologists for identification of such rarities encountered during invasive or non-invasive procedures.

    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.

    Cervical pregnancy is a rare form of ectopic pregnancy with potential grave consequences occurring in approximately 1:9,000 deliveries. It is life-threatening as the pregnancy is implanted in the endocervical canal and the trophoblast can penetrate through the cervical wall and into the uterine blood supply resulting in catastrophic haemorrhage. Historically, the treatment had been hysterectomy because of the considerable risk of life-threatening haemorrhage, but in the recent past various conservative management modalities have been applied to preserve fertility. Here, we report a case of successful (both medical and surgical) management of cervical ectopic pregnancy in a young woman. A 29-year-old, gravid 2, para1 and living 1 with previous caesarean section had presented with mild bleeding per vagina for 5 days following 7 weeks of amenorrhoea. Past menstrual, medical, surgical and family history were unremarkable except the previous caesarean section. On examination vital signs were normal but pelvic examination revealed a distended cervix with bulky uterus, without anyadnexal mass or tenderness and no cervical motion tenderness. Further transvaginal sonography showed a live cervical gestation of 7 weeks and 4 days and serum beta-HCG value of 1,03,113mIU/ml. Patient received conservative approach with combination of intraamniotic potassium chloride and methotrexate and suction curettage. Due to conservative approach emergency hysterectomy and blood transfusion was avoided. PMID:26816951

    Many retinal dystrophies result in photoreceptor loss, but the inner retinal neurons can survive, making them potentially amenable to emerging optogenetic therapies. Here, we show that ectopically expressed human rod opsin, driven by either a non-selective or ON-bipolar cell-specific promoter, can function outside native photoreceptors and restore visual function in a mouse model of advanced retinal degeneration. Electrophysiological recordings from retinal explants and the visual thalamus revealed changes in firing (increases and decreases) induced by simple light pulses, luminance increases, and naturalistic movies in treated mice. These responses could be elicited at light intensities within the physiological range and substantially below those required by other optogenetic strategies. Mice with rod opsin expression driven by the ON-bipolar specific promoter displayed behavioral responses to increases in luminance, flicker, coarse spatial patterns, and elements of a natural movie at levels of contrast and illuminance (≈50-100 lux) typical of natural indoor environments. These data reveal that virally mediated ectopic expression of human rod opsin can restore vision under natural viewing conditions and at moderate light intensities. Given the inherent advantages in employing a human protein, the simplicity of this intervention, and the quality of vision restored, we suggest that rod opsin merits consideration as an optogenetic actuator for treating patients with advanced retinal degeneration.

    We previously isolated pleiotrophin (PTN) from bovine bone as a protein and showed that it stimulated osteoblastic growth and differentiation. Further details of its function, however, have not been fully clarified. The aim of this paper was to elucidate the effects of PTN on bone morphogenetic protein (BMP)-induced ectopic osteogenesis. Recombinant human BMP (rhBMP)-2 (1.2 microg) was combined with a fibrous glass membrane, which had been established as an effective carrier. Various amounts of the purified bovine PTN (5, 10, 50, and 100 microg) or rhPTN (5 and 10 microg) were added to the rhBMP-2/carrier composites and implanted into rats subcutaneously as reported. It was found that the amount of bone induced in the system increased with the addition of 10 microg of either purified PTN or rhPTN. However, the amount of bone decreased with the addition of 50 or 100 microg of purified PTN dose-dependently, as judged by both alkaline phosphatase activity and calcium content in the retrieved implants. It was concluded that purified PTN or rhPTN, at ratios of concentration of 10-100 microg of PTN to 1.2 microg of rhBMP-2 in the carrier, regulated the ectopic bone-inducing activity of rhBMP-2.

    Foregut endocrine polypeptide-secreting APUD cells (Amine-Precursor-Uptake and Decarboxylation), in their embryologic migration from neural crest to foregut may become "arrested" in the mesoderm or in other ectopic locations. They may become hyperplastic, adenomatous or malignant. Eight illustrative patients are reported. One patient had "pancreatic hyperparathyroidism" with hypercalcemic crises, pancreatic apudocarcinoma, normal parathyroids, biologically active parathormone, but inert immunochemically to the usual parathyroid antisera. Two had gastrin-secreting malignancies in the mesoderm. Remission after excision, but eventual recurrence of the syndrome due to islet cell hyperplasia required total gastrectomy. One patient had a gastric corpus apudocarcinoma found prospectively with hypergastrinemia which required excision of the tumor. One patient had acromegaly with hypergastrinemia and antral gastrinosis treated by pituitary irradiation, One patient had the antral or intermediary type of the Zollinger-Ellison syndrome with moderate hypergastrinemia, duodenal ulcer and antral gastrinosis, treated by vagotomy and antrectomy. One patient had hyperparathyroidism with antral gastrinosis, treated by parathyroidectomy. One patient had malignant Zollinger-Ellison syndrome and developed associated thyroid parafollicular cell hyperplasia and parathyroid chief cell hyperplasia, treated by total gastrectomy and multiple endocrine excisions. These investigative observations demonstrate ectopic loci and associated hyperplasias which support the concept of migration and bizarre potentiality of polypeptide-secreting cells of the foregut.

    The authors describe, for the first time, bilateral, sequential large dacryocystoceles during pregnancy and review the literature for this presentation. A 26-year-old, 15-week pregnant woman presented with OD epiphora, diplopia, and pain in the setting of an inferomedial orbital mass. Surgical exploration and histopathology were consistent with a dacryocystocele, and a dacryocystorhinostomy was curative. She returned at 34-week gestation, with an identical presentation on the left side. Review of the literature reveals that dacryocystoceles occasionally present in adults; however, bilateral involvement may be unusual. Bilateral dacryocystoceles have not been previously reported in a pregnant woman.

    Fibromuscular dysplasia (FMD) describes a group of conditions which cause nonatheromatous arterial stenoses, most commonly of the renal and carotid arteries, typically in young women. We report a rare case of bilateral segmental renal infarction secondary to FMD in a young male patient. His initial presentation with loin pain and pyrexia resulted in a delay in the definitive diagnosis of FMD. He was successfully treated with bilateral balloon angioplasty. The delayed diagnosis in this patient until the condition had progressed to bilateral renal infarcts highlights the need for prompt investigation and diagnosis of suspected cases of FMD.

    Introduction Bilateral empyema is a rare and life-threatening condition that is difficult to treat. We herein report a case of bilateral empyema that was treated with simultaneous bilateral decortications via video-assisted thoracic surgery (VATS). Presentation of case A 38-year-old female complained of chest pain, dyspnea, and high grade fever lasting two weeks. Computed tomography revealed bilateral notching pleural effusion and pneumonia with atelectasis. Bilateral thoracic drainage was performed. From the right chest, white pus was drained, and Streptococcus anginosus was identified. The left drainage fluid was serous, and no bacteria were identified. We diagnosed the patient with right empyema and left para-pneumonic effusion consequent to pneumonia. Because conservative therapies could not resolve the inflammatory findings, simultaneous bilateral VATS decortications were performed. Both thoracic cavities had loculated pleural effusion. In contrast to the preoperative findings, white pus was found in not only the right, but also the left thoracic cavity. She had an uncomplicated postoperative course and recovered. Discussion Bilateral empyema that has developed to the fibrinopleural phase is difficult to treat with drains alone. Bilateral VATS decortications helped to make a definitive diagnosis and treat both sides simultaneously. Conclusion Simultaneous bilateral VATS decortications should be considered as a feasible and effective procedure for bilateral empyema that is refractory to medical treatment. PMID:25528031

    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.

    We are developing a bilateral pairing technique to help reduce false-positives identified by a single-view computer-aided detection (CAD) system for breast masses. In this study, we compare the performance of the proposed bilateral CAD to a single-view CAD. A database of 172 right/left breast pairs containing 205 biopsy-proven masses was used. Single-view CAD was run on each image using a lax selection threshold so that 5 objects per image were retained. The automated bilateral pairing algorithm identified all objects in a left breast mammogram "matching" a CAD detected object in the corresponding right breast image and visa-versa. Bilateral pairing was based on geometrical correspondence between objects with a matching score derived from a paired right/left object feature set and a linear discriminant analysis classifier. Leave-one out resampling was used to train/test the technique. We compared the FROC performances of the single-view CAD, the proposed bilateral technique and a modified CAD using manual pairing of bilateral structures. At a per-lesion detection sensitivity of 0.7, there were 3.8 FPs/image for the original CAD, 3.3 for the proposed technique, and 2.2 for the modified CAD using manual matching, a 12.6% and 42.1% reduction, respectively. At an FP rate of 1.0 per image, the sensitivities for the original CAD, the proposed technique and the modified CAD using manual matching were 0.47, 0.51 and 0.60, respectively. Preliminary results show that CAD with bilateral pairing did not achieve a significant FP-reduction.

  11. Bilateral and multiple cavitation sounds during upper cervical thrust manipulation

    2013-01-01

    Background The popping produced during high-velocity, low-amplitude (HVLA) thrust manipulation is a common sound; however to our knowledge, no study has previously investigated the location of cavitation sounds during manipulation of the upper cervical spine. The primary purpose was to determine which side of the spine cavitates during C1-2 rotatory HVLA thrust manipulation. Secondary aims were to calculate the average number of pops, the duration of upper cervical thrust manipulation, and the duration of a single cavitation. Methods Nineteen asymptomatic participants received two upper cervical thrust manipulations targeting the right and left C1-2 articulation, respectively. Skin mounted microphones were secured bilaterally over the transverse process of C1, and sound wave signals were recorded. Identification of the side, duration, and number of popping sounds were determined by simultaneous analysis of spectrograms with audio feedback using custom software developed in Matlab. Results Bilateral popping sounds were detected in 34 (91.9%) of 37 manipulations while unilateral popping sounds were detected in just 3 (8.1%) manipulations; that is, cavitation was significantly (P < 0.001) more likely to occur bilaterally than unilaterally. Of the 132 total cavitations, 72 occurred ipsilateral and 60 occurred contralateral to the targeted C1-2 articulation. In other words, cavitation was no more likely to occur on the ipsilateral than the contralateral side (P = 0.294). The mean number of pops per C1-2 rotatory HVLA thrust manipulation was 3.57 (95% CI: 3.19, 3.94) and the mean number of pops per subject following both right and left C1-2 thrust manipulations was 6.95 (95% CI: 6.11, 7.79). The mean duration of a single audible pop was 5.66 ms (95% CI: 5.36, 5.96) and the mean duration of a single manipulation was 96.95 ms (95% CI: 57.20, 136.71). Conclusions Cavitation was significantly more likely to occur bilaterally than unilaterally during upper cervical HVLA

    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.

    A prospective study was undertaken to assess the feasibility and safety of bilateral simultaneous percutaneous nephrolithotomy (BPNL) under single anesthesia. BPNL was attempted in 16 consecutive patients with upper tract urolithiasis suitable for percutaneous treatment bilaterally. Bilateral simultaneous PNL could be accomplished in 14 of 16 cases; the opposite side was abandoned in 2 due to technical reasons. The operating sides could be switched within a short period (15 min) by rotating the patient table by 180 degrees. The average total operating time and irrigation time was 83 and 43 min, respectively. A total of 29 tracts and 18 sessions were required for endourologic treatment of 28 units in 14 patients. There was no significant morbidity. Complete clearance was achieved in 11 of 14 patients; there was insignificant residue in 1, while 2 with major residue required adjunct JJ stenting and extra-corporeal shockwave lithotripsy. The average hospital stay was 5.4 days. After initial proficiency with endourology, preparedness for BPNL is advisable in all such cases.

    Studies of manual wheelchair propulsion often assume bilateral symmetry to simplify data collection, processing, and analysis. However, the validity of this assumption is unclear. Most investigations of wheelchair propulsion symmetry have been limited by a relatively small sample size and a focus on a single propulsion condition (e.g., level propulsion at self-selected speed). The purpose of this study was to evaluate bilateral symmetry during manual wheelchair propulsion in a large group of subjects across different propulsion conditions. Three-dimensional kinematics and handrim kinetics along with spatiotemporal variables were collected and processed from 80 subjects with paraplegia while propelling their wheelchairs on a stationary ergometer during three different conditions: level propulsion at their self-selected speed (free), level propulsion at their fastest comfortable speed (fast), and propulsion on an 8% grade at their level, self-selected speed (graded). All kinematic variables had significant side-to-side differences, primarily in the graded condition. Push angle was the only spatiotemporal variable with a significant side-to-side difference, and only during the graded condition. No kinetic variables had significant side-to-side differences. The magnitudes of the kinematic differences were low, with only one difference exceeding 5°. With differences of such small magnitude, the bilateral symmetry assumption appears to be reasonable during manual wheelchair propulsion in subjects without significant upper-extremity pain or impairment. However, larger asymmetries may exist in individuals with secondary injuries and pain in their upper extremity and different etiologies of their neurological impairment.

    Simultaneous, bilateral, and spontaneous rupture of the quadriceps tendon is a very rare injury. Individuals with this injury are usually predisposed by chronic renal disease with secondary hyperparathyroidism, gout, diabetes, and lupus erythematosus. Often, primary diagnostic confusion can lead to a delay in treatment. Two cases of a bilateral lesion of the quadriceps tendon, that were treated surgically using the technique of Scuderi, followed by an intense rehabilitation programme, are presented. Surgical treatment yields satisfactory results.

    Bilateral simultaneous tibial tubercle avulsion fractures are extremely rare. The present case was a 16-year-old boy who sustained bilateral simultaneous tibial tubercle avulsion fractures (Watson-Jones Type III) from jumping while playing basketball. Both fractures were treated successfully by open reduction and internal fixation with screws. Three years later, the patient had the screws removed because of knee pain and tenderness over the screws.

    Brown syndrome, characterized by a limitation of elevation in adduction and positive forced duction testing, is usually unilateral but occurs bilaterally in 10% of all cases. It may present as a congenital condition in one eye and develop in the other eye with no apparent cause. We present a case of bilateral Brown syndrome in which the right eye became involved within 1 year of surgery on the left eye for congenital Brown syndrome.

    A case of an ectopic lobe of the liver connected to a normal diaphragm is described. A 9-year-old, castrated male cat underwent thoracotomy for a pulmonary mass. The removed mass was attached to the diaphragm that histologically was ectopic liver. The ectopic liver had no connection with the main liver. Because the occurrence of ectopic supradiaphragmatic hepatic tissue is a possibility, this should be considered as a differential diagnosis for caudal pulmonary or caudal mediastinal masses in a cat. This report describes, to the authors' knowledge, the first case of ectopic hepatic tissue attached to the diaphragm of a cat. The authors also characterize the asymptomatic clinical presentation and radiographic findings of this cat and suggest further imaging with computed tomography in unusual case presentations.

    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. Ectopic Liver Tissue Attached to the Gallbladder Wall: a case report

    2009-01-01

    Introduction Ectopic liver tissue is a rare entity, reported to occur in several intra-, retro- and extra- peritoneal sites, including the gallbladder. It is usually detected incidentally, during laparoscopy, laparotomy, or autopsy. Several possible mechanisms may explain the development of liver ectopia. Although ectopic liver tissue is usually asymptomatic, it behaves like orthotopic liver, developing the same pathologic conditions. Case presentation We describe the case of a 54-year-old woman who was found to have a nodule attached to the gallbladder wall without any connection with the main liver, during an elective laparoscopic cholecystectomy for gallstone disease. The nodule was removed with the gallbladder and identified histologically as normal ectopic liver tissue. Conclusion It would seem sensible to resect the ectopic tissue if encountered during cholecystectomy for gallstones. Laparoscopic management of ectopic liver can be feasible. PMID:20126556

    Objective: To evaluate the importance of cytokine type in embryo implantation in uterus specified and activated macrophages interfere the tube movements and embryo retention in uterine tubes by smooth muscle relaxation and disrupting ciliary function. Therefore, increased risk of infection with HP during pregnancy, we investigated relation between Helicobacter pylori (HP) infection and prevalence of ectopic pregnancy (EP) in this study. Materials and methods: This is cross-sectional study from March 2012 to May 2013. Totally 207 women were enrolled randomly from which 101 had EP (Case group) and 106 were selected as control group with normal pregnancy. A 2-cc blood sample was taken from each patient to evaluate the specific IgG titer by ELISA method. All results of samples with positive H. pylori IgG were assayed for anti-CagA, IgG antibodies. A questionnaire was filled for each subject. The associations between CagA positive cases with odds of Ectopic pregnancy incidence were analyzed by using SPSS software, ver. 19 (Chicago, IL, USA). Results: Mean (± SD) of age were 21.0 ± 5.78 and 30.78 ± 5.10 years for cases and controls group respectively. These groups didn’t show any significance difference in age and parity.H. pylori IgG antibodies were positive among 99 and 103 (98.2% vs. 97.2%) in women with EP and normal pregnancy respectively. Relationship between IgG status and EP was not significant (OR = 1.31: 95% CI = 0.7-2.52, Pvalue = 0.37). In particular anti-CagA antibodies were positive among 45 and 39(45.92% vs. 36.97%) in women with EP and normal pregnancy respectively. Among women with CagA positive strains had higher odds of Ep (OR = 1.46: 95% CI = 0.8-2.65, Pvalue = 0.18), but it wasn’t significant. Conclusion: According to the result of this study there was not any association between HP infection and Ectopic pregnancy. We recommend more studies with larger sample size for determining the effect of CagA positive strains on EP. PMID:27648097

    In the era of emerging functional imaging techniques, an understanding of the effects of hormonal therapies on the scintigraphic appearance of endocrine organs is desirable to minimize the erroneous scan interpretation. The mechanisms by which changes in the scintigraphic appearance of endocrine organs occur however sometimes remain ambiguous. This case demonstrates the gallium-68 (Ga-68) DOTA-TATE positron emission tomography/computed tomography (CT) appearance of adrenal glands following management with steroidogenesis inhibitors. The potential mechanisms underlying this change are discussed. A 17-year-old boy with adrenocorticotropic hormone (ACTH) dependent Cushing's syndrome secondary to ectopic ACTH secretion underwent pre- and post-metyrapone and dexamethasone treatment Ga-68 DOTA-TATE scans 4 months apart. Pretreatment, both adrenals demonstrated normal symmetrical prominent Ga-68 DOTA-TATE uptake and normal CT appearance. The posttherapy scan revealed marked symmetrical suppression of Ga-68 DOTA-TATE uptake, but with bilateral adrenal hypertrophy on CT.

    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.

    The liver is largely responsible for free hemoglobin uptake, but the molecular mechanism of this phenomenon has never been revealed. This paper presents the results of the study on hemoglobin binding components of the hepatocyte membrane that were purified using affinity chromatography on a hemoglobin matrix and identified by peptide mass fingerprinting. Both F1-ATPase alpha and beta subunits were retrieved. The binding was confirmed via an intrinsic fluorescence quenching study using a purified recombinant F1-ATPase beta subunit, and the dissociation constant for the complex was estimated from the saturation binding curve (Kd = 7.5 x 10(-7) M). The results indicate that haemoglobin binds to hepatocyte ectopic F1-ATPase. We suggested the plausible role of the receptor in endocytosis of haemoglobin by the hepatocyte.

    The occurrence impacted teeth, single or multiple is very common. But, phenomenon of kissing molars is an extremely rare phenomenon. Mandibular third molars are the most common impacted teeth. Mandibular first or second molars does not share the same frequency of occurrence. But, there are rare cases in which the occlusal surfaces of impacted molars are united by the same follicular space and the roots point in the opposite direction, and are termed as kissing molars. Sometimes, these teeth will be associated with pathologies. This article reports a rare case of mandibular bilateral kissing molars. PMID:25918627

    The value of an analytical routine which could be used in the evaluation of clinical studies was assessed. Stepwise discriminant analysis with stepwise selection/elimination was used to reduce the amount of data without losing information before further analyses with canonical discriminant analysis. The purpose of canonical discriminant analysis was to reveal interactions between factors associated with the ectopic eruption of the first permanent molars. Two canonical discriminant functions were used to determine the accuracy of diagnosis and the effect of treatment. This information consisted of variables which were the most important (their ranks) and their single correlations (structure coefficients) to the function itself. This information was interpreted clinically. The coefficients of the canonical discriminant functions can be used for classification purposes. The use of a scatterplot instead of simple classification tables is suggested. The scatterplot was particularly informative on how well the procedure discriminated between groups. A table based on original data is included to allow the reader to test the validity of the findings on cases of his/her own. This multivariate strategy avoids spurious intercorrelations between two or more variables analysed as multiple single factors that has a high risk of erroneous conclusions.

    Bilateral renal cell carcinomas (RCCs) pose a challenge for clinical treatment and management. Most bilateral RCCs are sporadic, and do not show a hereditary pattern indicative of VHL syndrome or other inherited cancers. The origin and evolution of these sporadic bilateral RCCs remains elusive. We obtained normal and tumor samples from two male patients suffering from early stage synchronous bilateral clear cell RCC (ccRCC), and analyzed genomic DNA using whole exome sequencing and bisulfite pyrosequencing. We detected distinct 3p loss of heterozygosity (LOH) in both tumors in each patient. Two tumors within the same patient harbored distinct driver mutations and different CpG hypermethylation sites in the VHL promoter. Moreover, tumors exhibit independent evolutionary trajectories. Therefore, distinct 3p LOH, combined with contingent driver gene mutations and independent VHL hypermethylation, led to independent tumor origin and parallel evolution of bilateral ccRCC in these two patients. Our results indicate that tumors in these two cases were not due to common germline oncogenic mutations. They were results of multiple de novo mutations in each kidney, rather than primary ccRCC with contralateral renal metastasis. Therefore, histopathologic and genetic profiling from single tumor specimen may underestimate the mutational burden and somatic heterogeneity of bilateral ccRCCs. PMID:27383411

Design Secondary analysis of Medicaid administrative claims data. Setting United States. Subjects 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 2004–08 (n=19,135,106), and in California, Illinois and New York in 2000–03. Interventions None. Main Outcome Measure Number of ectopic pregnancies divided by the number of total pregnancies (spontaneous abortions, induced abortions, ectopic pregnancies, and all births). Results The 2004–08 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 2000–08. In all 14 states, Black women were more likely to experience an ectopic pregnancy compared to whites (Relative Risk 1.46, 95% Confidence Interval 1.45–1.47). Conclusions Ectopic pregnancy remains an important health risk for women enrolled in Medicaid. Black women are at consistently higher risk than whites. PMID:25439806

    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.

    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.

    Background In humans, the cause of arrested migration of the median thyroid anlage resulting in an ectopic sublingual gland is unknown. These ectopic glands have a normal follicular architecture but their thyrotropin-induced growth is insufficient, leading to congenital hypothyroidism in the vast majority of affected subjects. We hypothesized that arrested migration is due to premature differentiation [reflected by decreased telomere length (TL)], as observed in neural tube defects in mice. Methods Absolute TL and telomerase reverse transcriptase (hTERT) expression was measured in four ectopic and six orthotopic thyroids. TL was measured by quantitative polymerase chain reaction of genomic DNA, whereas hTERT expression was measured by quantitative polymerase chain reaction of total RNA. Results The mean ± standard deviation TL (in kilobases per diploid genome) was 140.45 ± 40.07 in ectopic and 97.50 ± 30.48 in orthotopic thyroids (p = 0.12). Expression of hTERT was quiescent in both ectopic and orthotopic thyroids. Conclusions Compared with orthotopic thyroids, TL shortening is not observed in ectopic thyroid tissues and, consequently, no compensatory hTERT expression was measured. This makes premature differentiation an unlikely cause of arrested migration and it suggests, indirectly, that ectopic thyroids are not at higher risk of cancer than orthotopic thyroids.

    Ectopic expression of the retinal determination gene eyeless (ey) induces the formation of supernumerary eyes on antennae, legs, wings, and halteres. These ectopic eyes form ommatidia that contain photoreceptors and accessory cells and respond to light. Here, we demonstrate that ectopic eyes on antennae and legs extend axonal projections to the central nervous system. Furthermore, electroretinograms and morphological evidence indicate that the photoreceptor axons of at least the antennal ectopic eyes can form completely constituted ectopic synapses with foreign postsynaptic elements and suggest that transmission at these sites may be functional. However, the ectopic axons do not connect to their correct optic lobe targets and do not project deeply into the neuropile, but rather form synapses at superficial positions in the neuropils. By means of confocal and electron microscopy we show that these ectopic synapses resemble normal synapses, albeit with some distinct morphological differences. Our data strongly suggest that the developmental programs controlling photoreceptor synaptogenesis and visual map formation depend to a considerable extent on presynaptic and thus photoreceptor-autonomous steps. Our data also suggest that photoreceptor axon projections and the establishment of the highly stereotypical neural circuitry in the optic lobe, the normal target neuropil, may depend on target-specific cues that appear to be absent from the antennal lobe and thoracic ganglion.

    Objective The aim of this study was to evaluate the difference in measured glomerular filtration rate (GFR) of an ectopic pelvic kidney between anterior and posterior image processing using Gates’ method of renal dynamic imaging. Methods A total of 10 patients were studied retrospectively, with a single ectopic kidney in the pelvic cavity and a contralateral kidney at its normal anatomical position confirmed by ultrasound, computed tomography, renal dynamic imaging, etc. All images of ectopic kidneys were processed, and GFRs were measured using anterior and posterior Gates’ method of renal dynamic imaging, respectively. The contralateral normal kidney was only processed on posterior imaging. The total GFRant of one patient, which was equal to the sum of the GFR of a normal kidney on posterior imaging and the GFR of an ectopic kidney on anterior imaging, was compared with the total GFRpost of two kidneys on posterior imaging, with the GFRtwo-sample from the two-sample method, and with the estimated GFR in the Chronic Kidney Disease Epidemiology Collaboration equation. All correlation analyses were carried out between GFRs obtained from three methods, and all patients were followed up. For statistical analysis, nonparametric rank tests were used, Bland-Altman graphs were plotted. Results The mean GFR of the ectopic kidney on anterior imaging was 27.48±12.24 ml/min/1.73 m2.

    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.

    Perineal ectopic anus in female infants is not a very uncommon congenital anorectal anomaly with opening into the low vaginal or vulvar region. However, ectopic anus with barrel gun perineum is a less common variety. Patients generally present with frequent history of constipation, but may seek medical help for just aesthetic reasons. We present here one such case of an asymptomatic seven years old female with the rare form of anterior ectopic anus with barrel gun perineum without any fistulous communications with an innovative method of demonstration of the anomaly by using ultrasound gel as rectal contrast in MRI pelvis.

    Ectopic adrenocorticotropic hormone (ACTH) syndrome is a rare cause of the Cushing's syndrome. The occurrence of the ectopic ACTH syndrome presenting with severe hypokalaemia, metabolic alkalosis, and hypertension has been highlighted in case reports. However, presentation with lower gastrointestinal perforation is not known. We report the case of a 70-year-old male patient with severe hypokalaemia, metabolic alkalosis, hypertension, and colonic perforation as manifestations of an ACTH-secreting small cell lung carcinoma. Ectopic ACTH syndrome should be kept in mind as a cause of hypokalaemia, hypertension, and intestinal perforation in patients with lung carcinoma. PMID:26894113

    This case describes an intraoperative incidental finding and surgical removal of ectopic liver tissue attached to the gallbladder during a standard laparoscopic cholecystectomy for acute cholecystitis. These anomalies are rare, with interesting associations and possible clinically relevant complications. The details of the case, along with a brief literature review of embryology, common ectopic sites, and associations/complications, are presented in this paper. Since laparoscopic cholecystectomy is a very common procedure, it is important to increase vigilance of ectopic liver tissues during surgeries to minimize complications and provide optimal management.

    The aim of this report is to present a case of a patient with bilateral lacrimal gland abscesses in the course of dacryoadenitis. A 45-year-old female patient with a long history of cocaine abuse presented with bilateral bacterial dacryoadenitis and upper lid inflammation with purulent discharge from a palpebral wound of the right upper lid. The diagnosis was confirmed with microbiology culture and an orbital CT scan, which revealed lacrimal gland abscesses. The patient admitted to vigorous eye scratching, which we believe was the mechanism responsible for the process. The infection resolved on targeted antibiotic therapy. This is the first reported case of bilateral infectious dacryoadenitis produced in a self-inflicted mechanism in a cocaine addict. PMID:25208047

    As radio frequency (RF) catheter ablation becomes increasingly prevalent in the management of ventricular arrhythmia in patients, an accurate and rapid determination of the arrhythmogenic site is of important clinical interest. The aim of this study was to test the hypothesis that the inversely reconstructed ventricular endocardial current density distribution from body surface potential maps (BSPMs) can localize the regions critical for maintenance of a ventricular ectopic activity. Patients with isolated and monomorphic premature ventricular contractions (PVCs) were investigated by noninvasive BSPMs and subsequent invasive catheter mapping and ablation. Equivalent current density (CD) reconstruction (CDR) during symptomatic PVCs was obtained on the endocardial ventricular surface in six patients (four men, two women, years 23-77), and the origin of the spontaneous ectopic activity was localized at the location of the maximum CD value. Compared with the last (successful) ablation site (LAS), the mean and standard deviation of localization error of the CDR approach were 13.8 and 1.3 mm, respectively. In comparison, the distance between the LASs and the estimated locations of an equivalent single moving dipole in the heart was 25.5 ± 5.5 mm. The obtained CD distribution of activated sources extending from the catheter ablation site also showed a high consistency with the invasively recorded electroanatomical maps. The noninvasively reconstructed endocardial CD distribution is suitable to predict a region of interest containing or close to arrhythmia source, which may have the potential to guide RF catheter ablation.

    OBJECTIVE: The authors review their experience with initial bilateral neck exploration under local anesthesia and hypnosedation for primary hyperparathyroidism. Efficacy, safety, and cost effectiveness of this new approach are examined. BACKGROUND: Standard bilateral parathyroid exploration under general anesthesia is associated with significant risk, especially in an elderly population. Image-guided unilateral approaches, although theoretically less invasive, expose patients to the potential risk of missing multiple adenomas or asymmetric hyperplasia. Initial bilateral neck exploration under hypnosedation may maximize the strengths of both approaches while minimizing their weaknesses. METHODS: In a consecutive series of 121 initial cervicotomies for primary hyperparathyroidism performed between 1995 and 1997, 31 patients were selected on the basis of their own request to undergo a conventional bilateral neck exploration under local anesthesia and hypnosedation. Neither preoperative testing of hypnotic susceptibility nor expensive localization studies were done. A hypnotic state (immobility, subjective well-being, and increased pain thresholds) was induced within 10 minutes; restoration of a fully conscious state was obtained within several seconds. Patient comfort and quiet surgical conditions were ensured by local anesthesia of the collar incision and minimal intravenous sedation titrated throughout surgery. Both peri- and postoperative records were examined to assess the safety and efficacy of this new approach. RESULTS: No conversion to general anesthesia was needed. No complications were observed. All the patients were cured with a mean follow-up of 18 +/- 12 months. Mean operating time was <1 hour. Four glands were identified in 84% of cases, three glands in 9.7%. Adenomas were found in 26 cases; among these, 6 were ectopic. Hyperplasia, requiring subtotal parathyroidectomy and transcervical thymectomy, was found in five cases (16.1%), all of which had gone

    Context: Ectopic ACTH/CRH syndrome is a rare cause of Cushing syndrome (CS), especially in children. The localization, work-up, and management of ACTH/CRH-secreting tumors are discussed. Setting: A retrospective study was conducted of patients under 21 years of age evaluated at the National Institutes of Health (NIH) for CS and diagnosed with ectopic ACTH/CRH-secreting tumors during the period 2009–2014. Patients: Seven patients with ectopic ACTH/CRH CS are included in this study with a median age 13.6 years (range 1–21), and 3 are female. Measurements: Clinical, biochemical, radiological features, treatment, and histological findings are described. Results: Seven patients were found to have ACTH/CRH-secreting tumors, all with neuroendocrine features. The site of the primary lesion varied: pancreas (3), thymus (2), liver (1), right lower pulmonary lobe (1). Patients underwent biochemical evaluation for CS, including diurnal serum cortisol and ACTH levels, urinary free cortisol levels (UFC), and CRH stimulation tests. All patients underwent radiological investigations including MRI, CT, and PET scan; imaging with octreotide and 68 gallium DOTATATE scans were performed in individual cases. Five patients underwent inferior petrosal sinus sampling; 4 patients had sampling for ACTH and CRH levels from additional sites. Three patients underwent trans-sphenoidal surgery (TSS), and 3 patients required bilateral adrenalectomy. Three patients (43%) died due to metastatic disease, demonstrating the high mortality rate. One of the unique findings in these seven patients is that in each case, their neuroendocrine tumors were ultimately proven to be co-secreting ACTH and CRH. This explains the enigmatic presentation, in which 3 patients initially thought to have Cushing's disease (CD) with corresponding pituitary hyperplasia underwent TSS prior to the correct localization of the causative tumor. Conclusions: Ectopic ACTH/CRH co-secreting tumors are extremely rare in children

    Choroidal osteoma is a an extremely rare (especially located bilaterally), benign, intraocular tumor, the type of choristoma. It occurs between 2-3 decades of life, women are particularly vulnerable. The main complication in 1/3 cases is a subretinal neovascularization which may cause bleeding. The gradually progressive decalcification develops within the tumour over time, which causes atrophy of the retinal pigment epithelium and Bruch's membrane deformity. The article presents a case of a 26-year-old woman with bilateral choroidal osteoma complicated by subretinal hemorrhage; the diagnosis was based on clinical examination (biomicroscopy and indirect ophthalmoscopy) as well as specialised tests including: ultrasonography, optical coherence tomography, and fluorescein angiography.

    Among the rare cardiac tumors, myxoma, which is mostly located in the left atrium, is the most common type. Bilateral atrial myxoma is extremely rare, and requires urgent surgery. The authors report the case of a 34-year-old male, who presented with one month of right hemiparesis and aphasia and subsequently diagnosed with bilateral atrial myxoma based on transthoracic echocardiography. An urgent operation for intra-cardiac tumor removal was performed with the biatrial approach. Once a diagnosis of myxoma has been made, an urgent operation for tumor removal is necessary due to the risk of serious complications, including sudden death from normal blood flow obstruction.

    The comprehension effects of changes in the spatial configuration of prose were examined with reading disabled children who differed in laterality preference. Specifically, 24 learning disabled boys were presented with prose materials in a standard, phrased, and backward (right to left) fashion. Measures of comprehension showed that text in the phrased and backward conditions differentially facilitated comprehension for the more bilateral subjects but had little effect on more right lateralized subjects. The results were discussed in terms of the instructional implications of alterations in the visual-spatial arrangement of prose materials for bilateral readers.

    A 6 yr old male Yorkshire terrier was presented for an ~6 yr history of progressive cough and dyspnea. Thoracic radiographs revealed a 6 cm diameter mass within the right caudal thorax. Thoracic ultrasound identified an intrathoracic mass ultrasonographically consistent with liver tissue and a chronic diaphragmatic hernia was suspected. Exploratory laparotomy was performed, but no evidence of a diaphragmatic hernia was identified. Thoracic exploration identified abnormal lung parenchyma. The accessory lung lobe was removed using a stapling devise near its base. The consolidated mass had the gross appearance of liver and was histologically identified as ectopic hepatic tissue. Ectopic hepatic tissue, unlike ectopic splenic and pancreatic tissue, is rare and generally has a subdiaphragmatic distribution. This solitary case report demonstrates that ectopic intrathoracic hepatic tissue should be considered a differential diagnosis for a caudal mediastinal mass.

    For goldfish (Carassius auratus), there are many varieties with different eye phenotypes due to artificial selection and adaptive evolution. Dragon eye is a variant eye characterized by a large-size eyeball protruding out of the socket similar to the eye of dragon in Chinese legends. In this study, anatomical structure of the goldfish dragon eye was compared with that of the common eye, and a stretching of the retina was observed in the enlarged dragon eye. Moreover, the homeobox-containing transcription factor Six3 cDNAs were cloned from the two types of goldfish, and the expression patterns were analyzed in both normal eye and dragon eye goldfish. No amino acid sequence differences were observed between the two deduced peptides, and the expression pattern of Six3 protein in dragon eye is quite similar to common eye during embryogenesis, but from 2 days after hatching, ectopic Six3 expression began to occur in the dragon eye, especially in the outer nuclear layer cells. With eye development, more predominant Six3 distribution was detected in the outer nuclear layer cells of dragon eye than that of normal eye, and fewer cell-layers in outer nuclear layer were observed in dragon eye retina than in normal eye retina. The highlight of this study is that higher Six3 expression occurs in dragon eye goldfish than in normal eye goldfish during retinal development of larvae.

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

    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. PMID:11828022

    Background: Pituitary adenomas are a common cause of endocrinal dysfunction, which comprise 10–20% of all intracranial tumors. Although almost all of them arise within the sella turcica, there are some rare cases in which a pituitary adenoma is located outside the intrasellar region, so it is defined as an ectopic pituitary adenoma (EPA). Case Description: We described a case of a 31-year-old male with a serum prolactin (PRL) value of 240 ng/ml Magnetic resonance imaging (MRI) showed a space-occupying mass within the sphenoid sinus (SS) which partially enhanced by gadolinium. MRI did not reveal any sellar floor defect and an empty sella was detected. As dopamine agonist treatment had failed in lowering the serum PRL level, he underwent surgical treatment. A transsphenoidal approach without opening the sellar floor was performed using an operating microscope and the lesion within the SS was completely removed. Conclusion: Although intrasphenoidal EPAs are rare findings, the presence of an endocrine disorder related to pituitary hormones, and a space-occupying mass within the SS associated with either a normal sellar pituitary gland or an empty sella must lead us to suspect this diagnosis.

    In vivo osteochondral defect models predominantly consist of small animals, such as rabbits. Although they have an advantage of low cost and manageability, their joints are smaller and more easily healed compared with larger animals or humans. We hypothesized that osteochondral cores from large animals can be implanted subcutaneously in rats to create an ectopic osteochondral defect model for routine and high-throughput screening of multiphasic scaffold designs and/or tissue-engineered constructs (TECs). Bovine osteochondral plugs with 4 mm diameter osteochondral defect were fitted with novel multiphasic osteochondral grafts composed of chondrocyte-seeded alginate gels and osteoblast-seeded polycaprolactone scaffolds, prior to being implanted in rats subcutaneously with bone morphogenic protein-7. After 12 weeks of in vivo implantation, histological and micro-computed tomography analyses demonstrated that TECs are susceptible to mineralization. Additionally, there was limited bone formation in the scaffold. These results suggest that the current model requires optimization to facilitate robust bone regeneration and vascular infiltration into the defect site. Taken together, this study provides a proof-of-concept for a high-throughput osteochondral defect model. With further optimization, the presented hybrid in vivo model may address the growing need for a cost-effective way to screen osteochondral repair strategies before moving to large animal preclinical trials.

    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.

    In order to clarify the peripheral mechanisms of ectopic persistent pain in a tooth pulp following pulpal inflammation of an adjacent tooth, masseter muscle activity, phosphorylated extracellular signal-regulated protein kinase (pERK) and TRPV1 immunohistochemistries and satellite cell activation using glial fibrillary acidic protein (GFAP) immunohistochemistry in the trigeminal ganglion (TG) were studied in the rats with molar tooth-pulp inflammation. And, Fluorogold (FG) and DiI were also used in a neuronal tracing study to analyze if some TG neurons innervate more than one tooth pulp. Complete Freund's adjuvant (CFA) or saline was applied into the upper first molar tooth pulp (M1) in pentobarbital-anesthetized rats, and capsaicin was applied into the upper second molar tooth pulp (M2) on day 3 after the CFA or saline application. Mean EMG activity elicited in the masseter muscle by capsaicin application to M2 was significantly larger in M1 CFA-applied rats compared with M1 vehicle-applied rats. The mean number of pERK-immunoreactive (IR) TG cells was significantly larger in M1 CFA-applied rats compared with M1 vehicle-applied rats. Application of the satellite cell inhibitor fluorocitrate (FC) into TG caused a significant depression of capsaicin-induced masseter muscle activity and a significant reduction of satellite cell activation. The number of TRPV1-IR TG cells innervating M2 was significantly larger in M1 CFA-applied rats compared with M1 vehicle-applied rats, and that was decreased following FC injection into TG. Furthermore, 6% of TG neurons innervating M1 and/or M2 innervated both M1 and M2. These findings suggest that satellite cell activation following tooth pulp inflammation and innervation of multiple tooth pulps by single TG neurons may be involved in the enhancement of the activity of TG neurons innervating adjacent non-inflamed teeth that also show enhancement of TRPV1 expression in TG neurons, resulting in the ectopic persistent tooth-pulp pain

After clinical and radiological examination, the patient was found to have bilateral lacrimal gland agenesis as well. No other dental, otological or systemic abnormality suggestive of lacrimo-auricular-dento-digital syndrome was detected. She was managed with bilateral dacryocystectomy. Algorithm for managing such nonconventional lacrimal outflow dysgenesis based on presenting symptoms and co existing epiphora is proposed. Rationale of preferring lacrimal sac excision instead of dacryocystorhinostomy in this case is also discussed. PMID:24526864

  4. "Ostrich sign" indicates bilateral vertebral artery dissection.

    Vertebral artery dissections (VADs) comprise about 2% of ischemic strokes and can be associated with trauma, chiropractic manipulation, motor vehicle collisions, whiplash, amusement park rides, golfing, and other motion-induced injuries to the neck. We present a case of bilateral extracranial VAD as a complication of conducting an orchestra. To our knowledge, this has not been documented in the literature. Conceivably, vigorous neck twisting in an inexperienced, amateur conductor may place excessive rotational forces upon mobile portions of the verterbral arteries, tear the intima, deposit subintimal blood that extends longitudinally, and cause neck pain and/or posterior fossa ischemic symptoms. Magnetic resonance angiography examinations of axially oriented slices of bilateral VADs resemble the face of an ostrich. This observation is similar to the "puppy sign," in which bilateral internal carotid artery dissections resemble the face of a dog. Craniocervical dissections of either the carotid or vertebral arteries have the potential to form an aneurysm, cause artery-to-artery embolism, or completely occlude the parent artery, resulting in an ischemic stroke. Because bilateral VADs in axial magnetic resonance angiographic sections stand out like the eyes of an ostrich, and because the fast identification of VADs is so critical, we eponymize this image the "ostrich sign."

    Background Symptomatic bilateral internal carotid occlusive disease is a rare but potentially devastating entity. Medical therapy alone is associated with high rates of mortality and recurrent stroke. The optimal management of this disease remains poorly understood. Methods A retrospective review of a prospectively maintained database was conducted for patients who presented with an acute stroke in the setting of bilateral carotid occlusive disease between May and October 2013. Results We identified 3 patients. The admission National Institutes of Health Stroke Scale score ranged from 4 to 7. All patients had small- to moderate-sized infarcts in the anterior circulation on presentation. Angiography confirmed bilateral internal carotid occlusions with collateral filling via the posterior communicating artery and retrograde filling via external carotid artery supply to the ophthalmic artery. All patients were initially managed with permissive hypertension and anticoagulation followed by carotid angioplasty and stenting. At 1-year follow-up, all patients demonstrated a modified Rankin scale score of 0-1. Conclusions Carotid stenting may be a safe and effective therapy for patients presenting with symptomatic bilateral carotid occlusions. PMID:27051405

  8. Fast and Provably Accurate Bilateral Filtering.

    PubMed

    Chaudhury, Kunal N; Dabhade, Swapnil D

    2016-06-01

    The bilateral filter is a non-linear filter that uses a range filter along with a spatial filter to perform edge-preserving smoothing of images. A direct computation of the bilateral filter requires O(S) operations per pixel, where S is the size of the support of the spatial filter. In this paper, we present a fast and provably accurate algorithm for approximating the bilateral filter when the range kernel is Gaussian. In particular, for box and Gaussian spatial filters, the proposed algorithm can cut down the complexity to O(1) per pixel for any arbitrary S . The algorithm has a simple implementation involving N+1 spatial filterings, where N is the approximation order. We give a detailed analysis of the filtering accuracy that can be achieved by the proposed approximation in relation to the target bilateral filter. This allows us to estimate the order N required to obtain a given accuracy. We also present comprehensive numerical results to demonstrate that the proposed algorithm is competitive with the state-of-the-art methods in terms of speed and accuracy. PMID:27093722

    2014-06-01

    Subclavian steal syndrome (SSS) is usually caused by unilateral subclavian artery (SA) occlusion, and bilateral SSS is very rare. Takayasu's arteritis (TA) is a chronic granulomatous form of vasculitis that affects the SA, most commonly in women aged 15-40 years. We report a rare case of bilateral SSS due to TA in a 52-year-old woman, who exhibited severe vertigo. Although her blood pressure was within the normal range and did not differ between her arms, Doppler ultrasonography revealed low antegrade blood flow in the right SA and retrograde flow in the left SA. Computed tomography angiography demonstrated complete obstruction of the bilateral SA proximal to the vertebral artery origin. The more marked decrease in the blood flow of the vertebrobasilar artery experienced in bilateral SSS compared with unilateral SSS is considered to have caused the severe rotatory vertigo in the present patient. Since the vascular conditions of TA progressively deteriorate, delayed diagnosis and treatment could result in poor outcomes and unfavorable prognosis. We suggest that SSS with TA might require an early detection and treatment as well as careful follow-up for preventing vertigo and other neurological deficits in the vertebrobasilar arterial region.

    Brain malformation with ectopic gray matter was visualized with magnetic resonance imaging in small-sized heads of prenatally exposed atomic bomb survivors. The identical brain malformation was reproduced in mice and its histogenesis was studied in the present experiment. Pregnant mice were exposed to {sup 60}Co {gamma}-irradiation at a single dose of 1.5 Gy on embryonic day 13 (E13), and then injected intraperitoneally with 30 mg/kg BrdU on E15. The extensive dead cells appeared throughout the brain mantle at 6 hours (h) after exposure. On E16 cell aggregations formed rosettes. On E18 a high proportion of BrdU-labeled cells reached the superficial layers of the cortical plate with the remaining cells located in the ectopic neuronal masses. The quantitative study showed that labeled cells in layers II to III were fewer and those in layers IV to VI more numerous in the prenatally irradiated adult mice than in controls. The anti-GFAP immunostaining revealed that the glial fibers in the irradiated mice were preserved, but disorganized. These findings suggested that the majority of migrating neurons were able to arrive at their normal layers, but some neurons remained due to the interrupted migratory pathway and eventually formed ectopic neuronal masses beneath the subcortical white matter. 60 refs., 5 figs., 1 tab.

    Background and Objectives: Mesh fixation during laparoscopic totally extraperitoneal repair is thought to be necessary to prevent recurrence. However, mesh fixation may increase postoperative chronic pain. This study aimed to describe the experience of a single surgeon at our institution performing this operation. Methods: We performed a retrospective review of the medical records of all patients who underwent bilateral laparoscopic totally extraperitoneal repair without mesh fixation for inguinal hernia from January 2005 to December 2011. Demographic, operative, and postoperative data were obtained for analysis. Results: A total of 343 patients underwent simultaneous bilateral laparoscopic totally extraperitoneal repair of 686 primary and recurrent inguinal hernias from January 2005 to December 2011. The mean operative time was 33 minutes. One patient was converted to an open approach (0.3%), and 1 patient had intraoperative bladder injury. Postoperative hematoma/seroma occurred in 5 patients (1.5%), wound infection in 1 (0.3%), hematuria in 2 (0.6%), and acute myocardial infarction in 1 (0.3%). Chronic pain developed postoperatively in 9 patients (2.6%); 3 of them underwent re-exploration. All patients were discharged home a few hours after surgery except for 3 patients. Among the 686 hernia repairs, there were a total of 20 recurrences (2.9%) in 18 patients (5.2%). Two patients had bilateral recurrences, whereas 16 had unilateral recurrences. Twelve of the recurrences occurred after 1 year (60%). Fourteen recurrences occurred among direct hernias (70%). Conclusion: Compared with the literature, our patients had fewer intraoperative and postoperative complications, less chronic pain, and no increase in operative time or length of hospital stay but had a slight increase in recurrence rate.

    Studies of manual wheelchair propulsion often assume bilateral symmetry to simplify data collection, processing, and analysis. However, the validity of this assumption is unclear. Most investigations of wheelchair propulsion symmetry have been limited by a relatively small sample size and a focus on a single propulsion condition (e.g., level propulsion at self-selected speed). The purpose of this study was to evaluate bilateral symmetry during manual wheelchair propulsion in a large group of subjects across different propulsion conditions. Three-dimensional kinematics and handrim kinetics along with spatiotemporal variables were collected and processed from 80 subjects with paraplegia while propelling their wheelchairs on a stationary ergometer during three different conditions: level propulsion at their self-selected speed (free), level propulsion at their fastest comfortable speed (fast), and propulsion on an 8% grade at their level, self-selected speed (graded). All kinematic variables had significant side-to-side differences, primarily in the graded condition. Push angle was the only spatiotemporal variable with a significant side-to-side difference, and only during the graded condition. No kinetic variables had significant side-to-side differences. The magnitudes of the kinematic differences were low, with only one difference exceeding 5°. With differences of such small magnitude, the bilateral symmetry assumption appears to be reasonable during manual wheelchair propulsion in subjects without significant upper-extremity pain or impairment. However, larger asymmetries may exist in individuals with secondary injuries and pain in their upper extremity and different etiologies of their neurological impairment. PMID:26125019

    The purpose of this study was to evaluate the long-term follow-up results of subcutaneous venous ports implanted in patients with bilateral mastectomies. We retrospectively reviewed the hospital charts and the electronic database of 17 patients with bilateral mastectomies whom had venous port implantation in our interventional radiology suit. A total of 17 ports were implanted to the paramedian (n = 3) and anterolateral (standard; n = 12) chest wall, on the trapezius muscle (n = 1), and to the antecubital fossa (n = 1). The mean age was 48.29 years (range: 35-60 years). The mean time interval from time of surgery to port implantation was 34 months (range: 1-84 months). The mean follow-up time was 15 months (range: 7-39 months). Follow-up parameters and classification of the complications was defined according to the SIR guidelines. No procedure-related complication occurred. A single case of mild late infection was noted and the infection rate was 0.19/1000 catheter days. Infusion chemotherapy administration was still going on in eight patients. Two patients died during the follow-up and four patients were lost after 6 months. Port removal was performed in three patients at follow-up because of the end of treatment. One trapezius port and one paramedian port weres among the removed ports without any problem. Although we have a limited number of patients, port placement to the anterior chest wall, either paramedian or anterolateral, on the trapezius muscle or to the antecubital fossa depending on the extent of the bilateral breast surgeries that can be performed with low complication rates by a careful patient and anatomical location selection by involving the patients in the decision-making process. We believe that patient education and knowledge of possible complications have high importance in follow-up.

  20. Ectopic KNOX Expression Affects Plant Development by Altering Tissue Cell Polarity and Identity[OPEN

    PubMed Central

    Rebocho, Alexandra B.

    2016-01-01

    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

    To maintain a particular cell fate, a unique set of genes should be expressed while another set is repressed. One way to repress gene expression is through Polycomb group (PcG) proteins that compact chromatin into a silent configuration. In addition to cell fate maintenance, PcG proteins also maintain normal cell physiology, for example cell cycle. In the absence of PcG, ectopic activation of the PcG-repressed genes leads to developmental defects and malignant tumors. Little is known about the molecular nature of ectopic gene expression; especially what differentiates expression of a given gene in the orthotopic tissue (orthotopic expression) and the ectopic expression of the same gene due to PcG mutations. Here we present that ectopic gene expression in PcG mutant cells specifically requires dBRWD3, a negative regulator of HIRA/Yemanuclein (YEM)-mediated histone variant H3.3 deposition. dBRWD3 mutations suppress both the ectopic gene expression and aberrant tissue overgrowth in PcG mutants through a YEM-dependent mechanism. Our findings identified dBRWD3 as a critical regulator that is uniquely required for ectopic gene expression and aberrant tissue overgrowth caused by PcG mutations. PMID:27588417

    Ectopic thyroid tissue has been found from the tongue to the diaphragm. The most common ectopic thyroid tissue has been found in the tongue, submandibular region, cervical lymph nodes, larynx, trachea, oesophagus, mediastinum, diaphragm and heart respectively. "Forgotten goiter" is an extremely rare disease which is defined as a mediastinal thyroid mass found after total thyroidectomy. In this case report, we discussed a 49 year-old female patient whose retrosternal ectopic thyroid tissue was detected by thyroid scintigraphy taken in postoperative period after total thyroidectomy performed with diagnosis of multinodular goiter. Papillary carcinoma was determined by the histopathological examination. Ectopic thyroid tissue was removed by performing sternotomy. We did not observe any postoperative surgical complications. 100 mCi dose of radioactive iodine was administered to the patient. Retrosternal ectopic thyroid tissue detected after total thyroidectomy is a rarely encountered condition. Therefore, retrosternal ectopic thyroid tissue existence should be definitely kept in mind in patients with no increase in thyroid stimulating hormone level after total thyroidectomy. PMID:26985161

    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

    When intracranial aneurysm is suspected, carotid arteriogram should be done not only on the suspected side but always on both sides. Without surgical intervention the prognosis of bilateral aneurysms is notoriously poor. With the aid of hypothermic anesthesia it is now possible to operate on both sides in a single procedure. This was demonstrated in a case in which both carotid arteries were simultaneously occluded twice during the surgical repair of bilateral carotid aneurysms. Occlusion was done once for eight minutes and once for ten minutes, without clinical evidence of brain damage. ImagesFigure 1.Figure 2. PMID:13671362

    Objective To investigate the mortality associated with cardiovascular diseases and the effect of estrogen treatment in women who underwent unilateral or bilateral oophorectomy before menopause. Design We conducted a cohort study with long-term follow-up of women in Olmsted County, MN, who underwent either unilateral or bilateral oophorectomy before the onset of menopause from 1950 through 1987. Each member of the oophorectomy cohort was matched by age to a referent woman from the same population who had not undergone any oophorectomy. We studied the mortality associated with cardiovascular disease in a total of 1,274 women with unilateral oophorectomy, 1,091 women with bilateral oophorectomy, and 2,383 referent women. Results Women who underwent unilateral oophorectomy experienced a reduced mortality associated with cardiovascular disease compared with referent women (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.67–0.99; P = 0.04). By contrast, women who underwent bilateral oophorectomy before age 45 years experienced an increased mortality associated with cardiovascular disease compared with referent women (HR, 1.44; 95% CI, 1.01–2.05; P = 0.04). Within this age stratum, the HR for mortality was significantly elevated in women who were not treated with estrogen through age 45 years or longer (HR, 1.84; 95% CI, 1.27–2.68; P = 0.001) but not in women treated (HR, 0.65; 95% CI, 0.30–1.41; P = 0.28; test of interaction, P = 0.01). Mortality was further increased after excluding deaths associated with cerebrovascular causes. Conclusions Bilateral oophorectomy performed before age 45 years is associated with increased cardiovascular mortality, especially with cardiac mortality. However, estrogen treatment may reduce this risk. PMID:19034050

  7. Hardware Implementation of a Bilateral Subtraction Filter

    2009-01-01

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    Four patients underwent stabilization surgery using both bilateral C2 pedicle screw (PS) and intralaminar screw (LS). Neural and vascular injury resulting from incorrect screw placement was assessed using computed tomography (CT). The evaluation of bone union was assessed by lateral flexion-extension X-ray films and CT. The symptoms were improved in all patients. There were no intraoperative complications. Furthermore, there were no cases of neurological worsening or vascular injury from incorrect screw placement. Failure of instrumentation or screw loosening during the follow-up period did not occur in any of the patients. All cases had accomplished bone union at the final follow-up. Theoretically, the stabilization technique using both bilateral C2 PS and LS at the same time can provide more stability than any other single technique. Simultaneous use of both bilateral C2 PS and LS is potentially a good choice for surgical repair. PMID:26435800

    Traumatic brain injuries (TBIs) affect millions of people each year. Research investigating repeated or serial damage in the form of lesions indicates that behavioral deficits are reduced in animals given sequential lesions separated by a sufficient period of recovery. In the lesion literature, this phenomenon is known as the serial lesion effect (SLE). Although the SLE phenomenon is established in the lesion literature, it has not been thoroughly investigated under current models of brain injury. In the current study, a controlled cortical impact of the bilateral frontal cortex was performed in either a single procedure or a serial procedure separated by two weeks. Rats were tested on the Morris water maze, bilateral tactile adhesive removal task, rotarod and Barnes maze task to determine behavioral deficits. Histology was performed to determine lesion size and astrocyte and microglial response. A serial lesion effect was demonstrated across a majority of the behavioral tasks. However, histological analyses did not suggest a clear mechanistic link to the behavioral phenomena. This is the first study to demonstrate the SLE in a model of TBI, suggesting that behavioral deficits may actually be reduced in repeated head injuries, given an adequate time window between injuries.

    1. Intracellular and extracellular recording techniques were used to study the increase in ectopic (i.e., nonsomatic) action-potential generation occurring among CA3 pyramidal cells during the kindling-like induction of electrographic seizures (EGSs) in this subpopulation of the hippocampal slice. Kindling-like stimulus trains (60 Hz, 2 s) were delivered to s. radiatum of CA3 at 10-min intervals. As EGSs developed, the frequency of ectopic firing increased markedly (by 10.33 +/- 3.29 spikes/min, mean +/- SE, P < 0.01). Several methods were applied to determine the initiation site for these action potentials within the cell (axons vs. dendrites). 2. Collision tests were conducted between known antidromic and orthodromic action potentials in CA3 cells to determine the critical period, c, for collision. Attempts were then made to collide ectopic spikes with known antidromic action potentials. At intervals less than c, ectopic spikes failed to collide with antidromic ones, in 5 of 10 cases. In these cells, this clearly indicates that the ectopic spikes were themselves of axonal origin. In the remaining five cases, ectopic spikes collided with antidromic action potentials at intervals approximately equal to c, most likely because of interactions within the complex system of recurrent axon collaterals in CA3. 3. Action potentials of CA3 pyramidal cells were simulated with the use of a compartmental computer model, NEURON. These simulations were based on prior models of CA3 pyramidal neurons and of the motoneuron action potential. Simulated action potentials generated in axonal compartments possessed a prominent inflection on their rising phase (IS-SD break), which was difficult to appreciate in those spikes generated in somatic or dendritic compartments. 4. An analysis of action potentials recorded experimentally from CA3 pyramidal cells also showed that antidromic spikes possess a prominent IS-SD break that is not present in orthodromic spikes. In addition to identified

    Purpose Herpes zoster ophthalmicus (HZO), thought to be a unilateral disease, results in loss of corneal sensation, leading to neurotrophic keratopathy. This study aimed to analyze bilateral corneal nerve changes in patients with HZO by in vivo confocal microscopy (IVCM) and their correlation with corneal sensation as a measure of nerve function. Design Prospective, cross-sectional, controlled, single-center study. Participants Twenty-seven eyes with the diagnosis of HZO and their contralateral clinically unaffected eyes were studied and compared with normal controls (n = 15). Methods In vivo confocal microscopy (Confoscan 4; Nidek Technologies, Gamagori, Japan) and corneal esthesiometry (Cochet-Bonnet; Luneau Ophthalmologie, Chartres, France) of the central cornea were performed bilaterally in all patients and controls. Patients were grouped into normal (>5.5 cm), mild (>2.5–5.5 cm), and severe (<2.5 cm) loss of sensation. Main Outcome Measures Changes in corneal nerve density, total nerve number, main nerve trunks, branching, and tortuosity were evaluated after IVCM and were correlated to corneal sensation, disease duration, and number of recurrences. Results Eyes with herpes zoster ophthalmicus had a significant (P<0.001) decrease in total nerve length (595.8±358.1 vs. 2258.4±989.0 μm/frame), total number of nerves (5.4±2.8 vs. 13.1±3.8), number of main nerve trunks (2.3±1.1 vs. 4.7±1.2), and number of nerve branches (3.2±2.3 vs. 8.4±3.7) as compared with controls. In the contralateral clinically unaffected eyes, total nerve length (1053.1±441.4 μm/frame), total number of nerves (8.3±2.9), and main nerve trunks (3.1±1.0) also were decreased significantly as compared with controls (P<0.01). Reduced nerve density, total nerve count, main trunks, and tortuosity was correlated significantly with corneal sensation across all subgroups (P<0.001). Conclusions Patients with unilateral HZO demonstrated a profound and significant bilateral loss of the

    Objective Cryopreservation of immature testicular tissue should be considered as an important factor for fertility preservation in young boys with cancer. The objective of this study is to investigate whether immature testicular tissue of mice can be successfully cryopreserved using a simple vitrification procedure to maintain testicular cell viability, proliferation, and differentiation capacity. Materials and Methods In this experimental study, immature mice testicular tissue fragments (0.5-1 mm²) were vitrified-warmed in order to assess the effect of vitrification on testicular tissue cell viability. Trypan blue staining was used to evaluate developmental capacity. Vitrified tissue (n=42) and fresh (control, n=42) were ectopically transplanted into the same strain of mature mice (n=14) with normal immunity. After 4 weeks, the graft recovery rate was determined. Hematoxylin and eosin (H&E) staining was used to evaluate germ cell differentiation, immunohistochemistry staining by proliferating cell nuclear antigen (PCNA) antibody, and terminal deoxynucleotidyl transferase (TdT) dUTP Nick- End Labeling (TUNEL) assay for proliferation and apoptosis frequency. Results Vitrification did not affect the percentage of cell viability. Vascular anastomoses was seen at the graft site. The recovery rate of the vitrified graft did not significantly differ with the fresh graft. In the vitrified graft, germ cell differentiation developed up to the secondary spermatocyte, which was similar to fresh tissue. Proliferation and apoptosis in the vitrified tissue was comparable to the fresh graft. Conclusion Vitrification resulted in a success rates similar to fresh tissue (control) in maintaining testicular cell viability and tissue function. These data provided further evidence that vitrification could be considered an alternative for cryopreservation of immature testicular tissue. PMID:27054121

    2015-01-01

    Provision of bilateral cochlear implants (CIs) to people who are deaf is partially justified by improved abilities to understand speech in noise when comparing bilateral vs unilateral listening conditions. However, bilateral CI listeners generally show only monaural head shadow with little improvement in speech understanding due to binaural unmasking. Sensitivity to change in interaural envelope correlation, which is related to binaural speech unmasking, was investigated. Bilateral CI users were tested with bilaterally synchronized processors at single, pitch-matched electrode pairs. First, binaural masking level differences (BMLDs) were measured using 1000 pulse-per-second (pps) carriers, yielding BMLDs of 11.1 ± 6.5 and 8.5 ± 4.2 dB for 10- and 50-Hz bandwidth masking noises, respectively. Second, envelope correlation change just-noticeable differences (JNDs) were measured. Stimuli presented at 1000 pps yielded lower JNDs than those presented at 100 pps. Furthermore, perfectly correlated reference stimuli produced lower JNDs than uncorrelated references, and uncorrelated references generally produced immeasurable JNDs. About 25% of JNDs measured in the CI listeners were in the range of JNDs observed in normal-hearing listeners presented CI simulations. In conclusion, CI listeners can perceive changes in interaural envelope correlation, but the poor performance may be a major limiting factor in binaural unmasking tested to date in realistic listening environments.

    Patient: Male, 3-day Final Diagnosis: Ectopic right testis in anterior abdominal wall Symptoms: — Medication: — Clinical Procedure: Testicular ultrasound and MRI abdomen Specialty: Radiology Objective: Unusual clinical course Background: Abnormal testicular descent can either be undescended or, less commonly, ectopic. Most undescended testes complete the course of descent by the first year of life only if these remain in the normal path of descent. The deviation of the testis may occur to an ectopic location during the transinguinal phase. Of the known ectopic sites, the anterior abdominal wall is the rarest site of testicular ectopia and to our knowledge only 3 cases of this nature have been reported in the available literature to date. Case Report: This rare case of testicular ectopia occurred in a 3-day-old boy in whom the right scrotal sac was empty; on abdominal ultrasound, the right testis was found in the subcutaneous tissues of the right antero-lateral abdominal wall. These findings were confirmed on abdominal MRI, where the right testis was seen beneath the skin between the subcutaneous tissues and external oblique aponeurosis. No aponeurotic or muscular defect was appreciable under the abdominal wall. The neonate underwent orchiopexy at the age of 6 months and remained uneventful postoperatively. Conclusions: Preoperative imaging is recommended to detect and confirm the ectopic site as well as the morphology of testis, thereby increasing the chance of surveillance and preservation of an ectopic testis. Imaging can serve as preoperative road mapping to localize the exact site for surgical exploration of an ectopic testis if there is no apparent or palpable swelling over the anterior abdominal wall.

    Introduction Isolated traumatic fractures of both Patellae, occurring at the same time, in an otherwise healthy person, are very rare. The Patella, as a subcutaneous and a cancellous bone, is vulnerable to injury. However, simultaneous injury to both Patellae without the involvement of any other bony injuries occurs infrequently, and only a few cases have been reported in the literature. Case Presentation We report a rare case of isolated, traumatic bilateral Patella fracture with unusual fracture patterns and briefly review the literature. Conclusions In simultaneous bilateral Patella fractures, good functional outcome can be expected following a stable surgical fixation and a structured rehabilitation regime. However, personality of the fracture determines salvage versus sacrifice of the Patella. PMID:27218047

    A high-level cognitive dichotomy ("language and context") is reviewed in relation to empirical findings concerning the functions of the human cerebral hemispheres. We argue that the right hemisphere's involvement in the generation of connotative and contextual information in parallel with the denotative and literal language functions of the left hemisphere provides an important insight into the organization of viable cognitive systems. The role of the corpus callosum in producing the dichotomy is discussed. Finally, the generation of asymmetrical activity in structurally symmetrical, bilateral neural nets is described. The model demonstrates how complementary memory states can be generated in bilateral nets without assuming different modes of information processing, provided that the nets have inhibitory, homotopic connections. Unlike excitatory connections, inhibitory connections are sufficient to generate asymmetric hemispheric activity without postulating intrinsic differences between the cerebral hemispheres.

    Although traumatic injury of the facial nerve is a relatively common condition in neurosurgical practice, bilateral lesions related to fracture of temporal bones are seldom seen. We report the case of a 38-year-old patient admitted to Intensive Care Unit after severe head trauma requiring ventilatory support (Glasgow Coma Scale of 7 on admission). A computed tomography (CT) scan confirmed a longitudinal fracture of the right temporal bone and a transversal fracture of the left. After successful weaning from respirator, bilateral facial paralysis was observed. The possible aetiologies for facial diplegia differ from those of unilateral injury. Due to the lack of facial asymmetry, it can be easily missed in critically ill patients, and both the high resolution CT scan and electromyographic studies can be helpful for correct diagnosis.

    Methods: 17 patients with Parkinson's disease were evaluated with a neuropsychological battery before and six months after bilateral pallidotomy. A comparison group (n = 8) was also assessed at six month intervals. Outcome variables were tests of memory, language, visuospatial function, attention, executive skills, and depression. Results: Despite a large number of variables studied, a significant postsurgical change was found only in performance of the tower of London task, a measure of planning abilities. The effect size of this change was larger than that of the comparison group, and a reliable change index score established that 5 of 13 surgical patients had statistically reliable reductions in planning performance. Conclusions: Patients with a young age of onset and long duration of Parkinson's disease who underwent bilateral pallidotomy had a relatively circumscribed reduction in neuropsychological functioning, being limited to motor planning efficiency. These data suggest that the cognitive role of the posteroventral globus pallidus is limited, at least in people with Parkinson's disease. PMID:12235317

    This case study describes a 37-year-old male who suffered a bilateral transverse acetabulum fracture with a fracture of the posterior wall and a double-sided dorsal hip dislocation in combination with a left-sided femoral head fracture (Pipkin IV) while skiing in a "fun park". The accurate diagnosis and presurgical planning was made by means of a computed tomography (CT) scan and a subsequent 3D reconstruction. After a primarily executed shielded repositioning of the bilateral hip dislocationearly secondary and anatomical reconstruction of the double-sided acetabulum fracture was possible using the Kocher-Langenbeck approach. A consistent physiotherapy as well as rehabilitation finally led to a positive clinical result for the patient.

    Inferior shoulder dislocation (luxactio erecta) is a rare lesion affecting approximately 0.5% of dislocations of this joint. The vast majority of these cases occur unilaterally. In September 2004, a 43 year old man was brought to the emergency room of the University Hospital of Santa Maria (HUSM) complaining of bilateral shoulder pain and inability to lower the arms, as a result of a fall with the arms abducted, while carrying out work activities. After physical examination and radiological exams, it was found that the patient had a bilateral inferior shoulder dislocation. He was referred to the surgical ward and after intravenous sedation, both shoulders were reduced by closed reduction using the traction-countertraction maneuver. The patient was discharged the day after the reduction. Both arms were immobilized with a velpeau sling in total adduction and intrarotation, with instructions to maintain immobilization for three weeks. The patient was also advised to receive physiotherapy. PMID:27047840

    We report a case of bilateral orbital hemorrhage as a complication of peribulbar anesthesia in a 78 year old man. Initially, unilateral orbital hemorrhage occurred but quickly spread to the contralateral side. Neuroophthalmological assessment revealed a proptosed tense globe with normal retinovascular findings. Visual acuity was adversely affected and this was conservatively managed with no lasting ophthalmic sequela. This patient’s case was reported as it illustrates an unusual complication of bilateral spread of orbital hemorrhage secondary to peribulbar anesthesia. It highlights how early ophthalmic assessment can ensure a good visual outcome in the setting of appropriate ophthalmic monitoring. The mechanisms of orbital hemorrhage spread and appropriate management options are discussed. PMID:27013899

    We analysed the effects of task symmetry during bilateral accurate force production tasks performed by the two feet. In particular, we tested a hypothesis that bilateral deficit would lead to higher indices of synergies defined as co-varied adjustments in the two forces across trials that reduced total force variability. The subjects produced steady-state force followed by a quick force pulse into the target. The two feet could be acting both into plantar flexion and into dorsiflexion (symmetrical tasks), or in opposite directions (asymmetrical task). We used the framework of the uncontrolled manifold hypothesis to quantify two variance components, one of which did not change total force (V UCM), while the other did (V ORT). Synergy indices during the asymmetrical task were higher than in either symmetrical task. The difference was due to higher V UCM (compared to the symmetrical plantar flexion task) or lower V ORT (compared to the symmetrical dorsiflexion task). The synergy index showed a drop (anticipatory synergy adjustment, ASA) starting 100-150 ms prior to the force pulse initiation. The ASA tended to be shorter and of a smaller magnitude for the asymmetrical task. This is the first demonstration of bilateral synergies during accurate force production by the legs. We conclude that bilateral deficit has no or weak effects on two-leg synergies. The results fit the earlier introduced scheme with two groups of neural variables defining average performance of a redundant system and patterns of co-variation among its elemental variables, respectively.

    2015-01-01

    Patient: Male, 21 Final Diagnosis: Idiopathic bilateral external jugular vein thrombosis Symptoms: Face engorgement • neck swelling Medication: — Clinical Procedure: None Specialty: Hematology Objective: Unknown ethiology Background: Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow’s triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. Case Report: This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Conclusions: Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present

    Brodie's abscess is a form of subacute osteomyelitis, which typically involves the metaphyses of the long tubular bones, particularly in the tibia. The diagnosis is usually made incidentally, as there are no accompanying symptoms or laboratory studies. Bilateral involvement at the proximal tibia is unusual. However, orthopaedic surgeons should be aware of this entity, as it may present without symptoms. Checking the contralateral limb for concomitant Brodie's abscess is recommended.

    The proportion of bilateral total knee replacements (BTKR) to unilateral total knee replacement (UTKR) in the United States is increasing. From 1990 to 2004, the use of BTKRs more than doubled for the entire civilian population and almost tripled among the female population. BTKRs can be performed in a single-stage or a staged procedure. Supporters of single-stage BTKR point out its low complication rates, high patient satisfaction, and cost-effectiveness. Others strongly believe that BTKR performed during the same anesthetic session is associated with increased morbidity and mortality. Single-stage BTKR surgery aims at reducing the exposure to repeated anesthesia, total hospitalization and recovery time, and cost, while maintaining patient safety and reducing the negative clinical and functional outcomes observed in patients undergoing UTKR or staged BTKR. This article presents the current concepts and controversies around BTKR surgery based on the authors' body of research and a review of the literature. We also present our institutional guidelines for candidates for single-stage BTKR. PMID:23283634

    Bilateral leg edema is a frequent symptom in older people and an important concern in geriatric medicine. Further evaluation is frequently not performed and simple therapy with diuretics is prescribed. Particularly in older patients, long-term use of diuretics can lead to severe electrolyte imbalances, volume depletion, and falls. In this case report we want to focus the physicians' attention on the necessity to determine the cause and show a correspondingly effective treatment for bilateral leg edema in older people. A thorough approach is required to recognize diseases and to avoid adverse drug events as geriatric patients often show an atypical presentation or minor symptoms. The cause of swollen legs is often multifactorial; therefore, the patient's individual history and an appropriate physical examination are important. Depending on the clinical symptoms, evaluation including basic laboratory tests, urinalysis, chest radiography, and echocardiogram may be indicated. The most probable cause of bilateral edema in older patients is chronic venous insufficiency. Heart failure is also a common cause. Other systemic causes such as renal disease or liver disease are much rarer. Antihypertensive and anti-inflammatory drugs can frequently cause leg edema, but the incidence of drug-induced leg swelling is unknown. With the help of this special case we tried to develop an approach to the diagnosis of symmetric leg edema in older patients, a problem frequently neglected in geriatric medicine.

    We report here a case study of a rare neurological patient with bilateral brain damage encompassing a substantial portion of the so-called “limbic system.” The patient, Roger, has been studied in our laboratory for over 14 years and the current article presents his complete neuroanatomical and neuropsychological profiles. The brain damage occurred in 1980 following an episode of herpes simplex encephalitis. The amount of destroyed neural tissue is extensive and includes bilateral damage to core limbic and paralimbic regions, including the hippocampus, amygdala, parahippocampal gyrus, temporal poles, orbitofrontal cortex, basal forebrain, anterior cingulate cortex, and insular cortex. The right hemisphere is more extensively affected than the left, although the lesions are largely bilateral. Despite the magnitude of his brain damage, Roger has a normal IQ, average to above average attention, working memory, and executive functioning skills, and very good speech and language abilities. In fact, his only obvious presenting deficits are a dense global amnesia and a severe anosmia and ageusia. Roger's case presents a rare opportunity to advance our understanding of the critical functions underlying the human limbic system, and the neuropsychological and neuroanatomical data presented here provide a critical foundation for such investigations.

    The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

    Acute spontaneous compartment syndrome of the forearm is rarely reported in the literature. It is typically associated with trauma or thromboembolism in the acute setting and repetitive exertional stress in the chronic setting. However it is rare for it to present bilaterally with no apparent underlying cause. We report the case of a young 31-year-old lady who presented to our Emergency Department with bilateral compartment syndrome of the forearm. Her presenting complaints included acute severe pain and swelling of the forearms bilaterally, with a decreased range of movement of the wrist and fingers. She also complained of numbness in all fingers. She had no history of recent trauma and ultrasound scans showed no evidence of vascular compromise. Past medical history was notable only for idiopathic hypertension and coeliac disease. The patient was taken to theatre urgently where flexor and extensor compartments and carpal tunnel were decompressed. Pronator Teres was found to be dusky initially but turned pink after decompression. All other muscles were normal. An interesting fact of this case was that combination of the high compartment pressures and anaesthetic related hypotension caused the forearm pulses to become impalpable at induction, these returned intra-operatively. The patient has been seen in the outpatient department following discharge. She is well apart from some mildly reduced grip strength in her right hand likely due to carpal tunnel decompression. No cause was found for the scenario after extensive medical investigation.

    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.

    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.

    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.

    Ectopic molar pregnancy is extremely rare, and preoperative diagnosis is difficult. Our literature search found only one report of molar pregnancy diagnosed preoperatively. Moreover, there is no English literature depicting magnetic resonance image (MRI) findings of ectopic molar pregnancy. We report a case of ectopic molar pregnancy preoperatively diagnosed using MRI. A literature review of 31 cases of ectopic molar pregnancy demonstrated that lesions have been found in the fallopian tube (19 cases, 61%), ovary (5 cases, 16%), cornu (3 cases, 10%), peritoneum (2 cases, 6%), uterine cervix (1 case, 3%), and cesarean scar (1 case, 3%). Abdominal pain and abnormal vaginal bleeding were reported in 70% and 61% of the patients, respectively. Twenty-one cases (67%) presented with rupture and hemoperitoneum. All patients underwent surgical resection or dilatation and curettage. Methotrexate therapy was performed in one case because residual trophoblastic tissue was suspected. A second operation was performed in one case of ovarian molar pregnancy because serum hCG levels increased again after primary focal ovarian resection. No patients developed metastatic disease or relapsed. These findings suggest the prognosis of ectopic molar pregnancy to be favorable. PMID:27648323

    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.

    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.

    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.

    Medical management for ectopic pregnancy is subject to substantial variations with different protocols and various routes of administration. Regardless the protocol used, methotrexate is currently the medical treatment of choice for ectopic pregnancy. The risk of a rescue surgery is a main concern. Recently, some studies suggested combining gefitinib and methotrexate to improve medical treatment and to decrease the need for reinjection and for additional surgery. Gefitinib is an orally administered EGF receptor-tyrosine kinase inhibitor. For tubal ectopic pregnancy, median recovery time was shorter after combination treatment with gefitinib and methotrexate. Toxicity reported with combination treatment was acneiform rash in 67% of cases and diarrhea in 42%. They were always transient and are known side effects of gefitinib previously described in lung cancer. These preliminary results are very promising but need to be explored further before wide distribution. For ectopic pregnancy, combining treatment seems to be interesting but results of the first randomized trial have to be evaluated first. For other indications, such as non-tubal ectopic pregnancy or choriocarcinoma, randomized studies are needed before wide use of the combination in current practice. PMID:26170723

    Heterotopic pregnancy is a rare and life-threatening condition which is defined as coexistent intrauterine and ectopic gestation. The risk of ectopic and heterotopic pregnancy is increasing due to the increased risk of multiple pregnancies with the aid of assisted reproductive technologies. However, it hardly happens in the setting of single embryo transfer, since single embryo transfer significantly reduces the incidence of multiple pregnancies. Surprisingly, we experienced a case of heterotopic pregnancy after a single embryo transfer caused by coincidental natural pregnancy during assisted reproductive technologies. An infertile woman who underwent, during her natural cycle, transfer of a single embryo that had been cryopreserved for 3 years was found to be heterotopically pregnant. After an early and successful management with laparoscopic right salpingectomy, she finally reached at full-term vaginal delivery. PMID:27462600

    Fibular osteoseptocutaneous flap has been widely used for unilateral mandibular reconstruction. However, reports about the effects of fibular osteoseptocutaneous flap for the reconstruction of bilateral mandibular defects are limited. In this study, we used free vascularized fibular flaps to successfully manage bilateral mandibular osteoradionecrosis(ORN) in 5 patients. Functional aspects were evaluated during the reconstruction process. All 5 patients had bilateral refractory ORN of the mandible and underwent radical resection between 2003 and 2011. The reconstruction surgery was performed in 2 stages using 2 free fibular flaps in 3 patients. In the other 2 patients, reconstruction was performed in a single stage using 2 separate flaps prepared from a single fibula. All patients had a healthy mandibular symphysis and meniscus of the temporomandibular joint, and these structures were preserved during the reconstruction.Of the 10 defects involving the mandible sides, 9 were successfully reconstructed. One microvascular composite flap failed because of radiation injury to the arterial endothelium at the recipient site. After the treatments, all patients had good esthetic and functional outcomes. Preoperative clinical features such as trismus and dysphagia were also markedly improved. Our surgical method may be an effective alternative for the clinical management of advanced bilateral mandibular ORN.

    Simultaneous bilateral femoral neck fracture is rare injury. Cases with this type of fracture have been reported in the literature since the 1950s, following the introduction of electroconvulsive therapy which generates violent hip muscle contractions. In young patients' simultaneous bilateral femoral neck fracture results from high energy trauma (car accident or fall from height) in a normal bone. Pathological changes in bone structure occurring in chronic kidney disease, vitamin D deficiency, osteomalacia, osteoporosis, metabolic imbalances and administration of corticosteroids explain the occurrence of this particular type of fracture following low-energy trauma. We present the case of a 90-year-old female patient who suffered a simple fall from her own height resulting in a Garden IV bilateral femoral neck fracture. Our therapeutic option in this patient was bilateral uncemented bipolar hemiarthroplasty in a single session using a single tray of sterile surgical instruments and two sterile drapes. Postoperative outcome was very good, allowing the initiation of functional recovery on the first postoperative day. Uncemented hemiarthroplasty proved to be a good choice in such a patient in the associated diseases may trigger the risk of cardiovascular disturbances specific to bone cement implantation syndrome.

    Human T-lymphotropic virus type 1 (HTLV-1) is a retrovirus that causes malignant and inflammatory diseases in ∼10% of infected people. A typical host has between 104 and 105 clones of HTLV-1–infected T lymphocytes, each clone distinguished by the genomic integration site of the single-copy HTLV-1 provirus. The HTLV-1 bZIP (HBZ) factor gene is constitutively expressed from the minus strand of the provirus, whereas plus-strand expression, required for viral propagation to uninfected cells, is suppressed or intermittent in vivo, allowing escape from host immune surveillance. It remains unknown what regulates this pattern of proviral transcription and latency. Here, we show that CTCF, a key regulator of chromatin structure and function, binds to the provirus at a sharp border in epigenetic modifications in the pX region of the HTLV-1 provirus in T cells naturally infected with HTLV-1. CTCF is a zinc-finger protein that binds to an insulator region in genomic DNA and plays a fundamental role in controlling higher order chromatin structure and gene expression in vertebrate cells. We show that CTCF bound to HTLV-1 acts as an enhancer blocker, regulates HTLV-1 mRNA splicing, and forms long-distance interactions with flanking host chromatin. CTCF-binding sites (CTCF-BSs) have been propagated throughout the genome by transposons in certain primate lineages, but CTCF binding has not previously been described in present-day exogenous retroviruses. The presence of an ectopic CTCF-BS introduced by the retrovirus in tens of thousands of genomic locations has the potential to cause widespread abnormalities in host cell chromatin structure and gene expression.

    Direct data collection from ventricular blood-pool studies were stored in frame mode in a computer and by means of a modified tape recorder, the blood-pool image and ECG were recorded on tape. At the end of the study the tape data were replayed into the computer. The ECG signal was passed through a trigger circuit that detected the R wave which was sampled by the computer once every msec. Contractions outside of the desired range could be rejected along with the subsequent contraction. Of seven patients whose calculated ejection fractions were changed by more than 0.03, all had frequent (one in 20) ectopic contractions. The distorted ventricular volume curves were effectively restructured by the constraining procedure, changing the end-systolic volume and EF. Computer modeling showed a linear relationship between the percent of ectopic contractions and the underestimate of ejection fraction. One ectopic beat in ten led to a 5% underestimate of EF.

    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

    Ectopic adrenal cortex is a rare entity. Usually found in male children; commonly located around kidney, retroperitoneum, spermatic cord and para-testicular region. Rarely, adults with heterotopic adrenal glands are described. Incidence in females is very less; though sometimes detected accidentally in hysterectomy specimens. We describe a case of ectopic adrenal cortical cell in paratubal region in a patient with mucinous cyst adenoma of ovary. A 26-year-old female presented with complains of menstrual irregularities and abdominal discomfort for 6 months. Investigations suggested a right ovarian cyst. Right ovarian cystectomy with partial salpingectomy was performed; histopathology revealed mucinous cyst adenoma. Sections from tube showed presence of ectopic adrenal cortical rest in the paratubal region, incidentally discovered on microscopy. We present this case because of its rarity in females, interesting presentation with another unrelated gynaecological pathology, its potentiality for malignant transformation and possible complications.

    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 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

Its design, scientifically logical for changing the direction of force, delivers a continuous distalizing and uprighting force. The Rect-spring can be easily manufactured at chairside and delivered on the same day without the need to take impressions or perform laboratory procedures. With proper activation, it can resolve a severely ectopically erupting molar within three months. It is relatively inexpensive and easy to deliver, causes little irritation, and is less time consuming for patients. It is worth utilizing before introducing Halterman or Humphrey appliances due to its simplicity and economical benefit. The purpose of this clinical report was to describe the design and the clinical application procedure for the Rect-spring and three successfully treated cases.

    The ectopic varices in patients with portal hypertension are those that occur at any level of the gastrointestinal (GI) tract, regardless of the varices that occur at the esophageal level. These ectopic varices account for 2–5% of the causes of GI bleeding varices. The risk of bleeding is quadrupled compared to the esophagogastric area, with a mortality of up to 40%. The transjugular intrahepatic portosystemic shunt, should be considered in cases secondary to recurrent bleeding varices. We present a case report of an urological emergency of bleeding in a urinary diversion secondary to ectopic varices successfully treated through the placement of transjugular intrahepatic portosystemic shunt. The condition described here is rare, but important, as it can be a life-threatening complication of portal hypertension. This kind of complication should be known by urologic surgeons managing patients with urinary diversions. PMID:26834901

    Stem cell-based strategies for bone regeneration, which use calcium phosphate (CaP)-based biomaterials in combination with developmentally relevant progenitor populations, have significant potential for clinical repair of skeletal defects. However, the exact mechanism of action and the stem cell-host-material interactions are still poorly understood. We studied if pre-conditioning of human periosteum-derived cells (hPDCs) in vitro could enhance, in combination with a CaP-based biomaterial carrier, ectopic bone formation in vivo. By culturing hPDCs in a biomimetic calcium (Ca(2+)) and phosphate (P(i)) enriched culture conditions, we observed an enhanced cell proliferation, decreased expression of mesenchymal stem cell (MSC) markers and upregulation of osteogenic genes including osterix, Runx2, osteocalcin, osteopontin, and BMP-2. However, the in vitro pre-conditioning protocols were non-predictive for in vivo ectopic bone formation. Surprisingly, culturing in the presence of Ca(2+) and P(i) supplements resulted in partial or complete abrogation of in vivo ectopic bone formation. Through histological, immunohistochemical and microfocus X-ray computed tomography (μCT) analysis of the explants, we found that in situ proliferation, collagen matrix deposition and the mediation of osteoclastic activity by hPDCs are associated to their ectopic bone forming capacity. These data were validated by the multivariate analysis and partial least square regression modelling confirming the non-predictability of in vitro parameters on in vivo ectopic bone formation. Our series of experiments provided further insights on the stem cell-host-material interactions that govern in vivo ectopic bone induction driven by hPDCs on CaP-based biomaterials. PMID:22269651

    Neural tissue injuries render voltage-gated Na+ channels (Nav) leaky, thereby altering excitability, disrupting propagation and causing neuropathic pain related ectopic activity. In both recombinant systems and native excitable membranes, membrane damage causes the kinetically-coupled activation and inactivation processes of Nav channels to undergo hyperpolarizing shifts. This damage-intensity dependent change, called coupled left-shift (CLS), yields a persistent or "subthreshold" Nav window conductance. Nodes of Ranvier simulations involving various degrees of mild CLS showed that, as the system's channel/pump fluxes attempt to re-establish ion homeostasis, the CLS elicits hyperexcitability, subthreshold oscillations and neuropathic type action potential (AP) bursts. CLS-induced intermittent propagation failure was studied in simulations of stimulated axons, but pump contributions were ignored, leaving open an important question: does mild-injury (small CLS values, pumps functioning well) render propagation-competent but still quiescent axons vulnerable to further impairments as the system attempts to cope with its normal excitatory inputs? We probe this incipient diffuse axonal injury scenario using a 10-node myelinated axon model. Fully restabilized nodes with mild damage can, we show, become ectopic signal generators ("ectopic nodes") because incoming APs stress Na+ / K+ gradients, thereby altering spike thresholds. Comparable changes could contribute to acquired sodium channelopathies as diverse as epileptic phenomena and to the neuropathic amplification of normally benign sensory inputs. Input spike patterns, we found, propagate with good fidelity through an ectopically firing site only when their frequencies exceed the ectopic frequency. This "propagation window" is a robust phenomenon, occurring despite Gaussian noise, large jitter and the presence of several consecutive ectopic nodes.

  2. The role of bilateral adrenalectomy in the treatment of congenital adrenal hyperplasia.

    This report summarizes follow-up studies in 18 patients who underwent bilateral adrenalectomy for congenital adrenal hyperplasia. Three of these patients were young children with null/null mutations of CYP21, and the other 15 were adrenalectomized because of difficulties in their management on conventional therapy. The average duration of follow-up was 59 months and represents an aggregate of 90 postoperative years. The adrenals were removed laparoscopically in 13 patients and by open flank incisions in five. Adrenal crises associated with severe illnesses occurred in five patients at times when their glucocorticoid substitution was suboptimal. All were responsive to appropriate therapy. Two of these patients were young children who had hypoglycemia during gastroenteritis or febrile illness associated with poor food intake or vomiting. Significant elevations of adrenal steroid precursors, presumably from ectopic adrenal rests, were observed postoperatively in eight of the patients. Patients and parents were nearly unanimous in their enthusiasm for adrenalectomy. In most, signs of androgen excess have decreased, and obesity has become less of a problem with lowering the dose of glucocorticoid. We conclude that adrenalectomy is a safe and efficacious method of managing congenital adrenal hyperplasia in selected patients. Prophylactic adrenalectomy in young children with double null mutations remains experimental. PMID:12843131

    A patient with ectopic pinealoma first presented with apparent anorexia nervosa and hypernatraemic coma. A history of diabetes insipidus two months previously was not known on admission to hospital. The diabetes insipidus was unmasked by the administration of steroids. Neuroendocrinal and neuropathological aspects of the case are discussed with reference to the march of symptoms due to the growth of the tumour. Histochemical evidence is presented supporting the similarity between ectopic pinealoma and seminoma which suggests that they may more properly be referred to as atypical teratomas.

    Conservative medical management of ectopic gestations may be difficult in patients with elevated levels of beta-hCG and cardiac activity. This case highlights the difficulty of managing such patients. Doppler flow studies and serum P, if available, should be used and can help determine those patients requiring repeated dosing of methotrexate. Patients using donor gametes and hormonal supplementation who subsequently develop an ectopic gestation may experience "rebound" ovulation, which further clouds the clinical picture. Careful follow-up using serial blood testing and ultrasound study is essential in the correct interpretation of a potentially confusing clinical picture.

    Portal hypertension and liver cirrhosis may predispose patients to varices, which have a propensity to bleed and cause significant morbidity and mortality. These varices are most commonly located in the gastroesophageal area; however, rarely ectopic varices may develop in unusual locations outside of this region. Haemorrhage from these sites can be massive and difficult to control; thus early detection and management may be lifesaving. We present a case of occult gastrointestinal bleeding in a patient with underlying alcoholic liver disease where an ectopic varix was ultimately detected with push enteroscopy. PMID:27595025

    Hepatic ectopic pregnancy is an uncommon form of extrauterine pregnancy. A 31-year-old woman had acute abdominal pain and distention. Laboratory examination showed significantly increased serum β-human chorionic gonadotropin level. Both ultrasound and MRI identified a lesion located at the right lobe of the liver. FDG PET/CT was performed to determine whether the other causes of elevated β-human chorionic gonadotropin level, which showed an oval mass with mid peripherally increased FDG activity. After surgery, pathological results confirmed a diagnosis of hepatic ectopic pregnancy. PMID:27454601

    Pierre Robin sequence has been associated with a number of ocular complications, including myopia, strabismus, Möbius syndrome, nasolacrimal duct obstruction, glaucoma, cataract, microphthalmos, coloboma of choroid, and retinal detachment. We report a 10-day-old boy who presented with micrognathia, glossoptosis, and cleft palate as well as multiple congenital anomalies. Ophthalmic examination was notable for bilateral maculopathy, with focal areas of retinal and retinal pigment epithelial atrophy. The association of Pierre Robin sequence and maculopathy has been reported only twice previously.

    An adolescent presented with a rhinosinusitis complicated with bilateral jugular veins and left superior ophthalmic vein thrombosis and respiratory distress with pulmonary hypertension. Blood culture was positive for Haemophilus influenzae and sinus puncture for Streptococcus constellatus. Evolution was under control after 1 week of appropriate antibiotherapy, antithrombotic and anti-inflammatory treatment. He had no neurologic, respiratory or ophthalmologic sequelae 6 months later. Despite lack of pharyngitis or isolation of anaerobic species on blood cultures, the picture was considered compatible with Lemierre syndrome. The risk for such a complication should be considered in cases of severe otorhinolaryngologic infection in young adults. PMID:14643536

    It is suggested that differentiated embryonic cells have a high specificity of molecular constitution as regards the surface layers surrounding their cellular membranes. Correspondingly, specific interface energies may characterize the early contacts between different cell types. The question is raised whether the morphology of the developing embryo may be understood in terms of cellular arrangements which minimize the total interface energy. Bilateral symmetry prevalent in early embryonic development of higher animals might be understood on the basis of the adoption of such a minimum energy principle if, in addition, one assumes that embryonic development is uniquely determined for a particular species.

    We report the case of a 14-year-old boy with bilateral congenital perisylvian syndrome as evidenced by polymicrogyria in the left and right frontotemporal regions, pseudobulbar paresis, seizures, and spastic diplegia. This is the first description of comprehensive neuropsychological assessment in a child with this syndrome. The results reflect significant impairments in auditory processing and independent learning and retention, but relatively preserved cognitive performance on interactive tasks involving frequent feedback and redirection. The findings are interpreted in the context of the neuropathology of this syndrome, with an emphasis on pragmatic implications for rehabilitation. PMID:18618376

    Observation of a case of progressive bilateral parietal thinning within a period of 14 years induced us to study skull films of 3 636 consecutive patients. Parietal thinning was found in 86 patients (2.37%). It was more common in women, with a sex ratio of 1:1.9. The mean age of the females was 72 years, and that of the males 63 years. Previous skull films of 25 of these patients were available and showed progression in 10. It is concluded that parietal thinning is a slowly progressive disease of middle-aged and old patients and is not an anatomical variant or congenital dysplasia of the dipole.

    We present a rare case of bilateral pseudoexfoliative deposits on both intraocular lens (IOL) implants in an 83-year-old woman with no other associated pathology, 5 years after cataract surgery. Pseudoexfoliation syndrome is the most common cause of secondary open-angle glaucoma worldwide and these deposits are usually found on the natural lens. The fact that pseudoexfoliative deposits have been found on IOL implants implies the need for a thorough examination in pseudophakic patients, for it could be the only sign of secondary glaucoma.

    A 51-year-old man developed severe quadriparesis without sensory loss after a fall on the occiput. When he was treated with corticosteroids, the weakness worsened slightly for 2 days, but he then progressively improved and ultimately walked unassisted. Two months later, postmortem examination disclosed metastatic tumors in the superior portion of each precentral gyrus. The subjacent white matter was edematous. No spinal cord abnormalities were found. The clinical, radiologic, and neuropathologic findings suggest that the quadriplegia resulted from these bilateral cerebral lesions and not from spinal cord dysfunction. The rapid development of cerebral edema, perhaps precipitated by trauma, seemed to account for the acute onset of symptoms in this case.

    Background. The risk of ovarian cancer is increased in the association of ovarian tumor, ascites, and hydrothorax with the significant elevated tumor marker CA-125. However, this association can be observed in a rare clinical and benign pathological entity, that is Demons-Meigs' syndrome. Objective. To describe a rare case of Demons-Meigs' syndrome observed in our department. Methods. A black African woman of 35 years old, seventh gravida and fourth parous, underwent a total abdominal hysterectomy with bilateral salpingoophorectomy for large bilateral ovarian masses associated with significant ascites, bilateral pleural effusion, and particular highly elevated tumor marker CA-125 (1835 UI/mL) in a pronounced general alteration condition. Results. The postoperative course was uneventful characterized by a complete remission of hydrothorax and ascites with normal level of CA-125 three months after tumor excision. Histology of both masses revealed a bilateral ovarian fibrothecoma, a benign tumor of the ovary, thus confirming the diagnosis of Demons-Meigs' syndrome. Conclusion. The Demons-Meigs syndrome, although it strongly mimics the clinical picture of malignant metastatic ovarian cancer, remains a disease with benign prognosis after surgical tumor resection. This is a rare condition that must be known and recognized by practitioners to avoid unnecessary practices. PMID:23431489

    Introduction: Patellar tendon rupture can occur due to multiple causes ranging from inflammatory pathologies to episodes of trauma. Extensor mechanism rupture is a rare complication of total knee arthroplasty (TKA). In most of these cases, the failure occurs as avulsion of patellar tendon from tibial tuberosity. We report a rare case with bilateral mid-substance patellar tendon rupture one month after bilateral total knee arthroplasty. Case Presentation: A 69-year-old male was operated for bilateral grade 4 osteoarthritis. On day 30 post-operative, he sustained bilateral patellar tendon rupture while getting up from toilet. He had a history of multiple steroid injections in the knee, which could have affected the tendon. The other etiologies could be inherent weakness of tendon due to diabetes and old age and micro-trauma/stretch associated with sudden correction of previous deformity by TKA. The management in our case was done by primary repair along with augmentation by autologous semitendinosus graft and suture anchor. Conclusion: The operating surgeon must be aware of the possibility of patellar tendon rupture following total knee arthroplasty. This will help the surgeon in early recognition and preparedness to handle such complications, should they arise. Surgeons may consider advising caution to both patient and rehabilitation team in cases with old age, chronic diabetes mellitus, and with a history of steroid injections. PMID:27703942

    The diagnostic strategy for asymptomatic patients with persistent bilateral bilar adenopathy often involves invasive procedures. The authors used Bayesian analysis to: (1) estimate the relative prevalences of diseases causing bilateral bilar adenopathy; (2) assess changes in the prevalence of disease by race, the presence of other clinical symptoms, and geography; and (3) determine the value of relevant noninvasive tests, including the angiotensin-converting enzyme (ACE) assay, gallium scan, and purified protein derivative (PPD), in order to assess when a strategy of watchful waiting is appropriate. The analysis indicated that the ACE assay, particularly when paired with the PPD, can identify many patients who might safely be managed without immediate invasive biopsy. Patients who are ACE+ and PPD- have an estimated probability of sarcoidosis of 0.95 or greater; patients who are ACE- and PPD+ have a probability of tuberculosis of 0.86 if black, 0.79 if white. In contrast, gallium scanning has no diagnostic role in this clinical situation. Bronchoscopic or mediastinoscopic biopsy has a limited role for patients who are ACE+ PPD- or ACE- PPD+ because of limited sensitivity. Patients who are both ACE- and PPD-, particularly if white, may have a high enough risk of lymphoma to consider invasive biopsy.

  19. Bilateral song production in domestic canaries.

    2004-09-01

    We studied the mechanism of song production in the outbred common or domestic canary (Serinus canaria). The contribution that each side of the syrinx makes to song was investigated by observing the effect of unilaterally occluding the left or right primary bronchus, followed by section of the ipsilateral branch of the tracheosyringeal nerve. In other birds with a bilaterally intact vocal system we monitored airflow through each side of the syrinx, together with subsyringeal pressure, during spontaneous song. Song production by domestic canaries is not strongly lateralized as it is in the conspecific song-bred waterslager strain. Some syllables are produced entirely on the left or right side of the syrinx, whereas others contain sequential contributions from each side. Low fundamental frequencies are produced with the left syrinx and high frequencies by the right syrinx, increasing the frequency range of domestic canary song compared to that of the waterslager strain. Midrange frequencies can be generated by either side. Syllables at repetition rates below about 25 s(-1) were accompanied by minibreaths, which were usually bilateral. Unilateral minibreaths were typically on the left side. At higher syllable repetition rates, minibreaths were replaced by a respiratory pattern of pulsatile expiration. Our data show that strong unilateral dominance in song production, present in the waterslager strain, is not a trait of the species as a whole and that the pattern of song lateralization can be altered by selective breeding for particular song characteristics.

    The paper presents the results of gait parameters as a function of unilateral weight. The object of the research was a woman walking on a stationary surface and carrying in his hand weights from 0 to 15 kg. Her movement was recorded by 6 cameras recording the location of 34 markers placed at appropriate points in the body. 3D reconstruction was performed for each of the reflecting markers. Tested signals were changes in the value the joint angles of ankle, knee and hip. On the basis of about 6 cycles of movement of each load, a model for the average gait cycle was developed. The result of the experiments are graphs of changes the joint angles as a function of time, bilateral cyclograms, synchronized bilateral cyclograms and regression lines. The conclusion of the study is to determine how one-sided load affects gait asymmetry. Simple and easy to interpret method of presentation of results were also shown. Studies were conducted using VICON system.

    Background. Despite advances in surgical repair of hiatus hernias, there remains a high radiological recurrence rate. We performed a novel technique incorporating bilateral oesophageal fixation and evaluated outcomes, principally symptom improvement and hernia recurrence. Methods. A retrospective study was performed on a prospective database of patients undergoing hiatus hernia repair with bilateral oesophageal fixation. Retrospective and prospective quality of life (QOL), PPI usage, and patient satisfaction data were obtained. Hernia recurrence was assessed by either barium swallow or gastroscopy. Results. 87 patients were identified in the database with a minimum of 3 months followup. There were significant improvements in QOL scores including GERD HRQL (29.13 to 4.38, P < 0.01), Visick (3 to 1), and RSI (17.45 to 5, P < 0.01). PPI usage decreased from a median of daily to none, and there was high patient satisfaction (94%). 57 patients were assessed for recurrence with either gastroscopy or barium swallow, and one patient had evidence of recurrence on barium swallow at 45 months postoperatively. There was an 8% complication rate and no mortality or oesophageal perforation. Conclusions. This study demonstrates that our technique is both safe and effective in symptom control, and our recurrence investigations demonstrate at least short term durability. PMID:26065030

    Motivation is drawn from the need to determine the sensory cues that animals such as blue crabs and lobsters use to track chemical odor plumes to locate food or mates. Major steps forward with this difficult problem can only be achieved through an appreciation of the spatial and temporal variation of concentration fields and the information content available to a forager in the plume. Here we discuss the usefulness of bilateral comparison to an animal tracking a turbulent plume. Instantaneous concentration fields of a chemical plume diffusing in a fully-developed turbulent open channel flow are measured using planar laser-induced fluorescence (PLIF). The plume is released iso-kinetically 25 mm above the smooth bed (z+ = 90), thus transport is mainly due to advection and ambient turbulence. A spatial correlation function in the spanwise direction is a dramatic indicator of the relative position of the centerline and distance from the source. The relative direction of the plume centerline can be estimated from an instantaneous bilateral comparison provided the sensors are separated by a distance that is relatively large compared to the spanwise integral length scale based on the spatial correlation function.

    Primary aldosteronism due to unilateral aldosterone-producing adenoma (APA) is a surgically curable form of hypertension. Bilateral APA can also be surgically curable in theory but few successful cases can be found in the literature. It has been reported that even using successful adrenal venous sampling (AVS) via bilateral adrenal central veins, it is extremely difficult to differentiate bilateral APA from bilateral idiopathic hyperaldosteronism (IHA) harbouring computed tomography (CT)-detectable bilateral adrenocortical nodules. We report a case of bilateral APA diagnosed by segmental AVS (S-AVS) and blood sampling via intra-adrenal first-degree tributary veins to localize the sites of intra-adrenal hormone production. A 36-year-old man with marked long-standing hypertension was referred to us with a clinical diagnosis of bilateral APA. He had typical clinical and laboratory profiles of marked hypertension, hypokalaemia, elevated plasma aldosterone concentration (PAC) of 45.1 ng dl(-1) and aldosterone renin activity ratio of 90.2 (ng dl(-1) per ng ml(-1 )h(-1)), which was still high after 50 mg-captopril loading. CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl(-1) confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl−1 confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

    The bilateral advantage for the perception of famous faces was investigated using a redundant target procedure. In experiment 1 we compared simultaneous presentation of stimuli (a) bilaterally and (b) one above the other in the central field. Results showed a redundancy advantage, but only when faces were presented bilaterally. This result lends support to the notion of interhemispheric communication using cross-hemisphere representations. Experiment 2 examined the nature of such communication by comparing bilateral presentation of identical face images, with bilateral presentation of different images of the same person. When asked to make a familiar/unfamiliar face judgement, participants showed evidence for a redundancy advantage under both bilateral conditions. This suggests that the nature of the information shared in interhemispheric communication is abstract, rather than being tied to superficial stimulus properties.

    Objective: The combination of a single pedicle local flap with tattooing for complete nipple areola complex (NAC) reconstruction is currently the most supported method. Although many technical descriptions of NAC reconstruction exist in the medical literature, there are no data that define the ideal areola size (diameter of the areola) after bilateral mastectomy and breast reconstruction considering the previous areola size. Methods: This was a 3-year (2009-2012) observational, analytical, and longitudinal prospective study with 103 patients who had undergone NAC tattooing as the last process of bilateral breast reconstruction after surgery for breast cancer. Statistical differences in the areola size and the jugulum-nipple distance before mastectomy and after reconstruction were analyzed by paired Student t tests with a 95% confidence interval. Results: The jugulum-nipple distance before mastectomy was 4.23 cm larger than after bilateral reconstruction (mean jugulum-nipple distance: 23.89 cm vs 19.66 cm), and for that reason shorter (more cephalad). The areola size before mastectomy was 1.59 cm larger than the one chosen by the patient for reconstruction (mean diameter of the areola: 5.25 cm vs 3.65 cm). Conclusions: We conclude that, after bilateral mastectomy and reconstruction, the jugulum-nipple distance is smaller and women prefer smaller areola sizes. PMID:24324847

    Bilateral cochlear implants seek to restore the advantages of binaural hearing by improving access to binaural cues. Bilateral implant users are currently fitted with two processors, one in each ear, operating independent of one another. In this work, a different approach to bilateral processing is explored based on blind source separation (BSS) by utilizing two implants driven by a single processor. Sentences corrupted by interfering speech or speech-shaped noise are presented to bilateral cochlear implant users at 0 dB signal-to-noise ratio in order to evaluate the performance of the proposed BSS method. Subjects are tested in both anechoic and reverberant settings, wherein the target and masker signals are spatially separated. Results indicate substantial improvements in performance in both anechoic and reverberant settings over the subjects’ daily strategies for both masker conditions and at various locations of the masker. It is speculated that such improvements are due to the fact that the proposed BSS algorithm capitalizes on the variations of interaural level differences and interaural time delays present in the mixtures of the signals received by the two microphones, and exploits that information to spatially separate the target from the masker signals.

    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.

  11. Double-strand break-induced recombination between ectopic homologous sequences in somatic plant cells.

    Homologous recombination between ectopic sites is rare in higher eukaryotes. To test whether double-strand breaks (DSBs) can induce ectopic recombination, transgenic tobacco plants harboring two unlinked, nonfunctional homologous parts of a kanamycin resistance gene were produced. To induce homologous recombination between the recipient locus (containing an I-SceI site within homologous sequences) and the donor locus, the rare cutting restriction enzyme I-SceI was transiently expressed via Agrobacterium in these plants. Whereas without I-SceI expression no recombination events were detectable, four independent recombinants could be isolated after transient I-SceI expression, corresponding to approximately one event in 10(5) transformations. After regeneration, the F1 generation of all recombinants showed Mendelian segregation of kanamycin resistance. Molecular analysis of the recombinants revealed that the resistance gene was indeed restored via homologous recombination. Three different kinds of reaction products could be identified. In one recombinant a classical gene conversion without exchange of flanking markers occurred. In the three other cases homologous sequences were transferred only to one end of the break. Whereas in three cases the ectopic donor sequence remained unchanged, in one case rearrangements were found in recipient and donor loci. Thus, ectopic homologous recombination, which seems to be a minor repair pathway for DSBs in plants, is described best by recombination models that postulate independent roles for the break ends during the repair process.

    Abstract Here we present the rupture of ectopic jejunal varices developing in a liver transplant recipient without portal hypertension, which was successfully treated with percutaneous transhepatic coil embolization. A 48-year-old man with massive melena was admitted to our department. He had undergone liver transplantation for hepatitis B virus-related liver cirrhosis 8 months before, and his postoperative course was satisfactory except for an acute cellular rejection. No evidence of bleeding was detected by upper endoscopy or colonoscopy, but dynamic multidetector computed tomography of the whole abdomen revealed an intestinal varix protruding into the lumen of the jejunum with suspected extravasation. There was no evidence of portal venous stenosis or thrombosis. Immediately upon diagnosis of the ruptured ectopic jejunal varix, percutaneous transhepatic coil embolization was performed, achieving complete hemostasis. The portal venous pressure measured during the procedure was within normal limits. He was discharged from the hospital 11 days after embolization and remained in stable condition without re-bleeding 6 months after discharge. This is the first report of an ectopic intestinal variceal rupture in an uneventful liver transplant recipient that was successfully treated with interventional percutaneous transhepatic coil embolization. Clinicians encountering liver transplant recipients with melena should be aware of the possibility of late-onset rupture of ectopic varices, even in those having an uneventful post-transplant course without portal hypertension.

    Ectopic salivary tissue is commonly found in intraparotid and periparotid lymph nodes. Warthin tumor is the most common tumor arising in ectopic salivary gland tissue and in intraparotid lymph nodes. Although rare, neoplastic transformation of the ectopic salivary tissues is conceivable and other types of salivary gland neoplasms arising in intraparotid lymph nodes have been reported. Herein we report a rare case of a 32-year-old Kuwaiti male who presented with a mass in the right parotid gland. A preoperative fine needle aspiration suggested Warthin tumor. The patient underwent a superficial parotidectomy. The specimen showed a mass within the parotid parenchyma abutting the deep margin. Hematoxylin and Eosin stained sections of the lesion showed solid islands and cysts composed of epidermoid cells, mucus cells, and intermixed smaller “intermediate” cells within an intraparotid lymph node. The tumor was seen infiltrating the parotid parenchyma at the deep margin. Metastasis from distant sites was ruled out clinically, and the diagnosis rendered was MEC, low-grade, arising from ectopic salivary tissue in an intraparotid lymph node. Such cases are extremely rare and the presence of malignancies within lymph nodes may pose a diagnostic pitfall, which can affect patient management. PMID:26697253

  16. Discriminatory hCG zone: its use in the sonographic evaluation for ectopic pregnancy.

    The most reliable ultrasonographic criteria for diagnosing ectopic pregnancy are based on the appearance of the uterus in the presence of a positive urine pregnancy test. The absence of an intrauterine sac signifies ectopic pregnancy, whereas its presence indicates intrauterine gestation. These criteria cannot be applied when serum pregnancy tests are used unless the serum human chorionic gonadotropin (hCG) level at which the sac of an intrauterine pregnancy becomes visible on ultrasound is known, because these tests are far more sensitive and identify pregnancy at an earlier stage than does sonar. In this study, the hCG level that distinguishes patients with intrauterine pregnancies in whom a gestational sac can be seen from those in whom it cannot be seen was determined and designated the discriminatory hCG zone. This zone lies between 6000 and 65000 mIU/ml. The absence of an intrauterine sac in conjunction with hCG values above this level signifies ectopic pregnancy; however, the absence of an intrauterine sac has no diagnostic significance when associated with hCG values below the discriminatory zone. An intrauterine sac associated with hCG levels above the discriminatory zone reliably indicates an intrauterine pregnancy, but at hCG values below the zone, it is suggestive of an abnormal pregnancy-either a missed abortion or an ectopic gestation.

  17. [Indications for methotrexate in gynecology outside the first-line treatment of ectopic tubal pregnancies].

    The objective of this work is to discuss the indications for methotrexate in gynecology outside the first-line treatment of tubal ectopic pregnancy. In tubal ectopic pregnancy, the prophylactic use of systemic methotrexate can be discussed when performing laparoscopic salpingotomy. In case of failure of salpingotomy, administration seems justified especially if it avoids re-intervention. The combination of methotrexate with other therapies such as mifepristone, potassium chloride or gefitinib is not recommended in the treatment of ectopic pregnancy. For non-tubal ectopic pregnancy, the intramuscular or local administration of methotrexate is an acceptable treatment for uncomplicated interstitial pregnancies. For uncomplicated cervical or cesarean scar pregnancies, the local administration of methotrexate should be considered as a first-line treatment. For ovarian pregnancies, methotrexate should not be a first-line treatment, surgical treatment remains the standard. Asymptomatic women presenting with a pregnancy of unknown location and plateauing serum hCG concentration<2000 UI/L can be managed expectantly: it is recommended to take an additional quantitative hCG serum level after 48 hours. Thus, methotrexate is not recommended in the first intention. Other gynecological indications were discussed: methotrexate is not recommended in the management of first-trimester miscarriages or in the management of placenta accreta.
