    Temporal bone Schneiderian papilloma may present as a primary tumour originating from the middle ear and mastoid process, or an extension from sinonasal disease. Both forms are rare, this being only the 18th case of primary temporal bone Schneiderian papilloma described to date. Although the current patient has remained disease free after excision of the papilloma, the reported recurrence rate is high, comparable to sinonasal Schneiderian papilloma with extrasinus extension. Malignant progression of primary Schneiderian papillomas is significantly reduced as compared to Schneiderian papillomas that extend from the sinonasal tract into the temporal bone. A positive human papilloma virus status, as found in this case, is a common feature and prognostic factor of sinonasal Schneiderian papilloma but an infrequent finding in temporal bone disease. Owing to the high recurrence rate, the risk of malignant progression and the absence of reliable prognostic markers, stringent follow-up consisting of otoscopy, nasendoscopy and imaging is essential.

    Full Text Available Inverted Schneiderian papilloma is an uncommon benign tumor that presents tendency to recur and propensity to be associated with malignancy in approximately 10% of the cases. Some of these lesions are isolated in the maxillary sinus, and predominantly affect white males with mean age of 50 years. We report a case of squamous cell carcinoma arising from inverted Schneiderian papilloma in the maxillary sinus extending to the mouth. The patient was submitted to extraction of a maxillary molar tooth four months before the exacerbation of the symptoms of nasal airway obstruction and facial enlargement. Computed tomography scan revealed a sinonasal mass causing opacification of the right maxillary sinus with destruction of the lateral nasal wall and maxillary sinus floor. The patient was referred to an oncology center for treatment and died from tumor progression one year after the cancer was diagnosed. The intention of this report is to alert dentists to include the inverted Schneiderian papilloma, either associated with squamous cell carcinoma, or not, in the differential diagnosis of maxillary sinus tumors with aggressive behavior, which may extend to the oral cavity or involve roots of teeth.

    Sinonasal inverted papilloma (SIP) is a benign tumor of the nasal cavity and sinus. SIP is characterized by aggressive malignant transformation and a high rate of recurrence. Inadequate removal of the tumor during surgery is one of the most significant contributors to SIP recurrence. A growing body of evidence suggests that molecular alteration in SIP, including human papilloma virus infections, single nucleotide polymorphisms of key genes, deregulation of signaling pathways and immunological changes, may lead to SIP occurrence and malignant transformation. However, the extent to which these molecular mechanisms contribute to SIP pathology and transformation remains unclear due to limited research. Further studies are warranted to elucidate the primary dependent factors that contribute to SIP etiology. The present article reviewed risk factors of progression and recurrence of SIP, including outdoor and industrial occupational exposure, smoking, septal deviation, SIP location, recurrent cases, stage of SIP-associated squamous cell carcinoma and choice of surgical method.

    The recurrence rate of sinonasal inverted papillomas (SNIP) is 15-20%. However, few studies have investigated patient-dependent factors related to recurrence of SNIPs. To analyze risk factors, including human papilloma virus (HPV) infection and smoking, as well as other factors, for recurrence of SNIPs. Fifty-four patients who were diagnosed with SNIP and underwent surgery were enrolled: 39 men and 15 women, with the mean age of 54.0 years. Their mean follow-up was 40.6 months. Demographics and information about the history of smoking, previous surgery, tumor extent, follow-up, and recurrence were reviewed retrospectively. Those patients whose tumors were associated with malignant transformation were excluded in this study. HPV detection and genotyping in the tumor specimens were performed with the HPV DNA chip, a polymerase chain reaction-based DNA microarray system. Seven patients (13.0%) had recurrence, with a mean time to recurrence of 39.8 months. Recurrence rates in T1, T2, T3, and T4 of the Krouse staging system were 0% (0/4), 8.3% (2/24), 17.4% (4/23), and 33.3% (1/3), respectively (p > 0.5). Eight patients (14.8%) were positive for HPV DNA. All of these patients belonged to the group without recurrence (p > 0.5). However, recurrence rates according to HPV DNA positivity were not statistically different (0% versus 15.2%). Three (42.9%) in the group with recurrence and four (8.5%) in the group without recurrence were smokers (p < 0.5). Smoking was associated with recurrence of SNIP. However, HPV infection is not a recurrence of SNIP risk factor.

    Despite the progress achieved in the treatment of breast cancer, there are still many unsolved clinical issues, being the diagnosis, prognosis, and treatment of papillary diseases, one of the highest challenges. Because of its unpredictable clinical behavior, treatment of intraductal papilloma has generated a great controversy. Even though considered as a benign lesion, it presents high rate of malignant recurrence. This is the reason why there are clinicians supporting a complete excision of the lesion, while others support an only expectant follow-up. Previous results of our group suggested that procollagen 11 alpha 1 (pro-COL11A1) expression correlates with infiltrating phenotype in breast lesions. We analyzed the correlation between expression of pro-COL11A1 in intraductal papilloma and their risk of malignant recurrence. Immunohistochemistry of pro-COL11A1 was performed in 62 samples of intraductal papilloma. Ten out 11 cases relapsed as carcinoma presents positive staining for COL11A1, while just 17 out of 51 cases with benign behaviour present immunostaining. There were significant differences (P < 0.0001) when comparing patients with malignant recurrence versus nonmalignant relapse patients. These data suggest that pro-COL11A1 expression is a highly sensitive biomarker to predict malignant relapse of intraductal papilloma and it can be used as indicative factor for prevention programs.

    This review will highlight the indications and benefits of office-based therapy for recurrent respiratory papillomatosis (RRP) and discuss the utilization of photo-dynamic lasers and adjuvant medical therapy in office-based settings. Office-based management of RRP allows for more timely interventions, is preferred by the majority of patients, and negates the risk of general anesthesia. Current literature argues for the utilization of KTP laser over CO2 laser for office-based treatment of RRP. Medical therapies for RRP are limited, but agents such as bevacizumab are promising and have been shown to reduce disease burden. Medical therapies that can induce disease remission are still needed. Office-based procedures save time and healthcare expenses compared to like procedures in the operating room. However, the increased frequency for office-based procedures predicts similar overall healthcare costs for office-based and OR laser excision of RRP. Office-based management of RRP is a feasible and well-tolerated strategy in appropriately selected patients with adequate local anesthesia.

    A 19-year-old woman with a history of juvenile laryngeal papillomatosis (JLP), treated since childhood with multiple resections, was admitted with symptoms of pneumonia. A chest X-ray and CAT-scan revealed multiple lung cysts and a bronchoalveolar lavage detected human papilloma virus 11. The patient responded well to antibiotics. A body plethysmography showed small lung volumes and low diffusion capacity for carbon monoxide, but normal volume diffusion capacity divided by alveolar volume. Pulmonary cystic disease should be considered when patients with JLP have symptoms of pneumonia.

    OBJECTIVE To investigate the advantages of applying microdebrider removal of juvenile-onset recurrent respiratory papillary epithelioma (JORRP), using an endoscopy-assisted prop-up laryngoscope.METHODS The degree of severity of the neoplasms was divided into 3 scores (i.e. 1 point for a slight degree, 2 points for a moderate and 3 points for a severe degree). The involvement of 22 respiratory and digestive sub-areas was evaluated and the total accumulative scoring and the scores for the lesions in the vocal area were calculated and subgrouped.All the papillary epitheliomas were excised using a laryngeal micro-debrider or the micro laryngeal forceps under endoscopy-assisted suspension laryngoscopy. The differences between applications of the two modes of treatment for the cases of the groups with same scoring were compared as follows: the operation time, interval of operation, recent vocal quality after operation, postoperative scarring and incision of the trachea, as well as the distribution of tumors in a re-operation.RESULTS The 142 operative procedures were performed in 33 pediatric patients, with application of a laryngeal microdebrider in 14 cases and excision in 19. Compared to the excision group (EG), the laryngeal microdebrider group (MDG) displayed many superior features, such as a short operation time, long interval between operations, obvious improvement in vocal quality soon after operation, and a low frequency of subsequent tumors. There was a significant difference between these modes of the operation. A postoperative incision of the trachea was required in 2 cases of EG, whereas no post-operation was needed in the MDG.CONCLUSION There are many advantages in using laryngeal micro-debrider removal of JO-RRP. The procedure is simple and convenient,having a distinct operating field, precise incision, minor wounds, fewer complications and better vocal quality soon after operation, as well as quicker rehabilitation and longer intervals between operations

    Recurrent laryngeal papillomatosis (RLP), a chronic disease associated with human papilloma virus (HPV), requires serial surgical procedures for debulking, resulting in debilitating long-term dysphonia, laryngeal scarring, and rarely malignant degeneration. Human papilloma virus 11 tumors have been widely accepted as more aggressive than HPV 6 tumors; however, the clinical course has been difficult to predict at disease onset, and the biologic mediators of proliferation have not been well characterized. A retrospective case review of 43 patients (4 months to 10 years at diagnosis) was performed on children treated for recurrent laryngeal papillomatosis. Patient charts were reviewed for demographic information, age at RLP diagnosis, approximate frequency of surgical intervention, and absolute number of surgical procedures performed. Human papilloma virus subtyping was performed. Expression analysis of the HPV-encoded E6 and E7 oncogenes was performed by reverse-transcriptase polymerase chain reaction. Fourteen patients had subtype 11 (33%) and 29 patients had subtype 6 (67%). As expected, HPV 11 patients showed a more aggressive clinical course than HPV 6 patients. However, 38% of patients with subtype 6 (11 patients) followed a clinical course that mirrored the more severe subtype 11 patients. These patients expressed the disease at a younger age (P < 0.0002) and showed higher levels of E6 and E7 oncogenes compared to the patients with the more indolent course. Although HPV subtype and early onset of RLP are well characterized prognostic factors, our study documents the significance of E6 and E7 oncogene expression as potential biologic mediators of proliferation and thereby clinical behavior.

    Inverted papilloma (I.P.) is a rare naso-sinusal benign tumour, with epithelium surface inversion to inside the stroma. Extension to intracranial temporal fossa and middle ear has been reported in few cases in the literature. This involvement may be derived from either direct extension from sino-nasal cavity via the Eustachian tube or primary middle ear involvement secondary to meta-plastic changes of the middle ear mucosa. Here, we report a case of inverted papilloma in a male patient, with multiple recurrences, middle ear and intracranial involvement into the temporal fossa with posterior development of malignancy. This patient had received multiple surgeries and radiotherapy but despite of that, his disease recurred several times. As a conclusion, inverted papilloma is a benign tumour with an aggressive course, tendency to recurrence and progression to malignancy. Intracranial and temporal fossa involvements are rare and the treatment depends of the symptoms and the severity of the disease. (authors)

    Full Text Available Abstract Background Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases. While endoscopic resection performed by an experienced surgeon is definitely a minimally invasive therapy, an open approach is not necessarily associated with functional and aesthetic disadvantages. This case report describes the treatment of inverted papilloma by an open approach. This has been described before but the new gold standard of endoscopic resection has to be taken into account before any treatment decision is made nowadays. Case presentation Contrast-enhanced magnetic resonance imaging of the head and neck area was indicated in a 72-year-old white German man who presented with suspected squamous cell carcinoma of his lower lip. Magnetic resonance imaging additionally revealed a 3×2 cm2 polycyclic arranged mucosal thickening with cystic and solid contrast affine shares at the antral laterocaudal area of his right maxillary sinus, extending from his right lateral nasal wall to his maxillary sinus floor. He received antral polypectomy with medial maxillectomy via a unilateral LeFort I osteotomy approach. His pterygoid plate was preserved. A histological examination demonstrated a tumor composed of hyperplastic squamous epithelium protruding into the stroma (surface epithelial cells grew downward into the underlying supportive tissue, thus producing a grossly convoluted cerebriform appearance. Two weeks later, the

    To investigate the Human papilloma viral types 6 and 11 in a large pediatric population in XinJiang and the different expression in chinese and uyghur pediatric population. Using polymerase chain reaction (PCR), we analyzed paraffin embedded tissue in 42 cases of juvenile Recurrent Respiratory Papillomatosis (JRRP)and determined the HPV types 6 and 11, and to correlate these results with retrospectively analysis about those cases who were consecutively treated in our ENT department, meanwhile we carry out a critical review of the literature of JRRP. A total HPV infection positive rate was 97.61% (41/42), and HPV11 positive rate was 63.41% (41/26), HPV6 positive rate was 36.58% (41/15). In uyghur patient HPV11 positive rate was 65.38% (17/26), HPV6 positive rate was53. 33% (8/15). in Chince patient HPV11 positive rate was 34.61% (9/26), HPV6 positive rate was 46.67% (7/15). Juvenile laryngeal papilloma is associated with HPV11, HPV6 infection and we considered that HPV11 infection may be the important guideline of the evaluation of disease prognosis. but no statistical signtificance was determined in the patients of various ethnic groups in Xin jiang (P > 0.05).

    2016-11-01

    Inverted papilloma is a rare sinonasal tumor that mainly occurs in adults during the 5th decade. Three characteristics make this tumor very different from other sinonasal tumors: a relatively strong potential for local destruction, high rate of recurrence, and a risk of carcinomatous evolution. Etiology remains little understood, but an association with human papilloma virus has been reported in up to 40% of cases, raising the suspicions of implication in the pathogenesis of inverted papilloma. Treatment of choice is surgery, by endonasal endoscopic or external approach, depending on extension and tumoral characteristics. Follow-up is critical, to diagnose local relapse, which is often early but may also be late. The seriousness of this pathology lies in its association with carcinoma, which may be diagnosed at the outset or at recurrence during follow-up. It is important to diagnose recurrence to enable early treatment, especially in case of associated carcinoma or malignancy. A comprehensive review of the international literature was performed on PubMed and Embase, using the following search-terms: "sinonasal" [All Fields] AND ("papilloma, inverted" [MeSH Terms] OR ("papilloma" [All Fields] AND "inverted" [All Fields]) OR "inverted papilloma" [All Fields] OR ("inverted" [All Fields] AND "papilloma" [All Fields])). We reviewed all articles referring to sinonasal inverted papilloma published up to January 2015. The present article updates the state of knowledge regarding sinonasal inverted papilloma.

    The aim of this study was to describe cross-sectional imaging features of recurrent papilloma of the nasal fossa and paranasal sinuses and to evaluate the role of MR and CT in the postoperative follow-up of this lesion. Magnetic resonance imaging and CT of ten patients who presented recurrence of inverted papilloma were reviewed and correlated to initial imaging, endoscopy, and surgical reports. Imaging patterns of recurrent inverted papilloma are identical to those of initial tumors and recurrence location is closely related to the site of the former lesion. Magnetic resonance is more efficient than CT for the diagnosis and evaluation of extensions. Magnetic resonance supplies the deficiencies of endoscopy in case of extensions to the frontal sinus or the lateral recess of the antrum, especially if mucosal hyperplasia or sinusitis is associated. Magnetic resonance imaging is the first imaging modality to perform in the follow-up after removal of inverted papilloma. (orig.)

  2. Does human papilloma virus play a role in sinonasal inverted papilloma?

    2014-02-01

    Inverted papillomas are a benign sinonasal tumor with a propensity for recurrence and malignant transformation. Although many investigations have been made into the nature of this disease, its etiology and causes for malignant transformation have yet to be fully elucidated. It is the authors' objective to present a review on management of the disease and evaluate the present relationship between human papilloma virus (HPV) and inverted papilloma. A causal relationship between HPV and the pathogenesis and progression of inverted papilloma has been posited since the 1980s. Although widely varied HPV detection rates have been reported, recent studies have noted a substantial increase in both recurrence and malignant transformation in HPV-infected inverted papillomas. However, exact cellular mechanisms by which infection leads to subsequent recurrence and development of carcinoma have yet to be elucidated. Evidence exists suggesting that HPV infection plays a role in the progression of inverted papilloma and confers an increased risk for recurrence and malignant transformation. PCR is the preferred detection method, and fresh or frozen specimens are the ideal source of tissue for evaluation. Although multiple studies have detected an association between HPV and inverted papilloma (both recurrent and malignant transformation), further studies are necessary to elucidate the underlying molecular pathways before an association can be changed to causation.

    Our observations suggest that human papilloma virus (HPV) 6/11 is the main causative agent of laryngeal papilloma and that detection of active HPV DNA expression may be helpful in identifying patients with aggressive recurrent laryngeal papilloma. HPV is assumed to be the main causative agent of this disease. We investigated the expression of the entire genotype of HPV in cases of laryngeal papilloma and correlated their expression with the clinical course of the disease. Seventy cases of laryngeal papilloma were evaluated for the presence of the HPV genome by in situ hybridization (ISH) using wide-spectrum HPV DNA probe. Specific types of HPV infection were determined by DNA ISH using type-specific HPV DNA probes (HPV 6, 11, 16, 18, 31, 33). Separate analyses were conducted comparing viral types, frequency of recurrences and duration of disease-free periods. We detected HPV DNA in 40 of the 70 laryngeal papilloma cases (57%). In particular, HPV DNA was detected in 75% of the juvenile types. There were significant associations between HPV and laryngeal papilloma (p<0.01). Among the HPV-positive cases, major specific types were HPV 6/11 (97%). Significant associations were also noted between viral expression and clinical course.

    To explore the relationship between the expression of EGFR and STAT3 in human laryngeal papilloma and its biological behavior. Reverse transcription polymerase chain reaction(RT-PCR), immunohistochemical staining and Western blot were used to evaluate the mRNA and protein expression of EGFR and STAT3 (p-STAT3) in 42 laryngeal papilloma tissues and 15 samples of normal laryngeal tissue, and the relationship between the protein expression of them and clinic pathological parameters was also analyzed. The mRNA expression levels of EGFR and STAT3 in laryngeal papilloma tissue were significantly higher than that in normal laryngeal tissue (P papilloma than normal laryngeal tissue by immunohistochemistry and western blot (P papilloma (P papilloma (P papilloma,, and the persistent activation of STAT3 gene plays an important role in the recurrence and canceration of laryngeal papilloma.

    A 72-year-old woman with primary biliary cirrhosis complained of dry cough and wheezing. Chest computed tomography showed a tumor arising from the posterior wall of the trachea. Bronchoscopic examination revealed that the tumor was cauliflower-like, with two small polypoid tumors. They were diagnosed as multiple squamous papillomas. The main tumor was recurrent and removed by repeated microwave coagulation therapy (MCT) through bronchoscopy, whereas the two polypoid tumors were likely to disappear spontaneously. Human papilloma virus (HPV) type 6 DNA was detected in the tumor by polymerase chain reaction (PCR) amplification, suggesting that this virus was the cause of her papillomas.

    Human papilloma virus (HPV) infection is involved in both juvenile and adult laryngeal papilloma. We wished to determine which types of adult laryngeal papilloma were clinically related to HPV infection. We hypothesized that multiple-site and recurrent papillomas would have a strong relationship to HPV and conducted the present study to test this hypothesis. Thirteen male patients with adult laryngeal papilloma who underwent resection of papilloma between August 2006 and September 2009 were studied. We examined the relationships between whether the tumor was solitary or multiple, presence or absence of recurrence after surgery, and HPV infection. High-risk HPV types (HPV-DNA types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68) and low-risk HPV types (6, 11, 42, 43, and 44) were tested by a liquid-phase hybridization method. In addition, HPV typing was performed for patients positive for low-risk HPV types. Twenty patients with laryngeal carcinoma or laryngeal leukoplakia were enrolled as the control group. In the laryngeal papilloma group, all patients tested were negative for high-risk HPV and 69.2% were positive for low-risk HPV. Typing performed for seven of the patients who tested positive for low-risk HPV showed that one patient was positive for HPV-11, whereas the remaining six patients were positive for HPV-6. All patients with recurrent laryngeal papillomatosis (RLP) were positive for low-risk HPV. All patients who were positive for low-risk HPV had RLP. Tumor samples from repeat operations were positive for low-risk HPV in all patients tested. HPV was not detected in the control group. The relationship between RLP and low-risk HPV was strong, with all cases that were positive for low-risk HPV showing recurrence. Tumor tissue resected at the time of repeat surgery was positive for low-risk HPV in all cases tested. Copyright © 2013 The Voice Foundation. Published by Mosby, Inc. All rights reserved.

  7. Surgical pneumatization through maxillary sinus wall and the schneiderian membrane: A new technique to facilitate augmentation of the maxillary sinus

    2017-01-01

    Full Text Available A minimum subantral bone height in the posterior maxilla may require a bone augmentation where a sinus lift procedure is the most commonly used technique, either preceding or simultaneously with the implant installation. While elevating the Schneiderian membrane ruptures are common, possibly resulting in less bone formation. In this paper, we propose the surgical pneumatization of the Schneiderian membrane as a new technique to minimize the risk of such complications. This can be achieved mainly by creating a hole for the immediate and increased passage of air through the Schneiderian membrane and the maxillary sinus wall above the region of augmentation.

    Sinonasal papilloma (SNP) is a rare benign lesion characterized by high recurrence rate and malignant transformation. This study aimed to investigate the prevalence of human papilloma virus (HPV) infection in these lesions in South of Iran. In this cross sectional retrospective study, a total of 41 patients, 38 SNP and 3 SNP/Squamous cell carcinoma cases, from 2007 to 2014 were studied. Human papilloma virus (HPV) DNA detection was performed by nested PCR method and positive cases were analyzed for high risk HPV-16 and HPV-18. HPV was detected in 31.7%; HPV- 16 in 4.9% and HPV 18 was not detected at all. Dysplastic epithelium was detected in 53% that was not associated with HPV. Three cases were accompanied with malignant transformation that HPV genome was detected in only one case and none of them were positive for HPV16 /18 genomic DNA. Current research suggests that HPV may be involved in the development of SNP. But the high risk HPV is not important in malignant transformation. More studies are needed to elucidate the possible etiologic mechanism between HPV, inverted papilloma, and squamous cell carcinoma.

    Manic patients with (N = 12) and without (N = 27) Schneiderian first rank symptoms (SFRS) were compared with regard to age, age at illness onset, presence of good prognostic signs, psychopathologic variables, treatment, and family history. The lack of group differences seen on many variables is consistent with the notion that SFRS do not define a separate schizo-affective manic subtype with differences in etiology or outcome.

    Full Text Available Introduction. Primary osteosarcoma of the breast is extremely rare, and an osteosarcoma arising from an intraductal papilloma is exceptional. Case Presentation. A 72-year-old Saudi Arabian woman presented with a solid, bone-containing breast mass that was diagnosed as primary osteosarcoma of the breast on biopsy. She had a history of untreated intraductal papilloma. Treatment was completed with a modified mastectomy after excluding extramammary metastases. However, she subsequently developed multiple recurrent lesions at the same site. Conclusion. Primary osteogenic sarcomas of the breast are very rare. Although the main treatment is resection the optimal management remains uncertain and prognosis is poor.

    Evaluate the efficacy of 5-Aminolevulinic Acid Photodynamic Therapy (PDT) in medical treatment of nasal inverted papilloma (NIP). Three patients with nasal inverted papilloma were treated with 5-Aminolevulinic Acid Photodynamic Therapy at our department from April to September 2012. The efficacy and adverse effects of 5-Aminolevulinic Acid Photodynamic Therapy were evaluated during 6-8 months of follow-up medical examination. After treated with 5-Aminolevulinic Acid Photodynamic Therapy, the nasal inverted papillomas were removed. No recurrence was found during the 6-8 months of follow-up medical examination. The major adverse effects were mild erosion, pain, and exudation. 5-Aminolevulinic Acid Photodynamic Therapy appears to be an effective treatment of nasal inverted papilloma. It can clear the papilloma lesions and is well tolerated by the patients. Copyright © 2013 Elsevier B.V. All rights reserved.

    Fungiform papillomas are benign mucosal neoplasms presenting as a unilateral exophytic mass involving the anterior portion of the nasal septum. In this study, we present an exceptional case of a bilateral fungiform papilloma with a synchronous verrucous carcinoma of the nasal septum. A case study with a review of the literature concerning malignant changes in fungiform papilloma. The general consensus in most of the literature is that malignant change in fungiform papilloma is exceptional. Our patient is probably the third reported case of verrucous carcinoma of the nasal septum, and the first report of a bilateral fungiform papilloma with a synchronous verrucous carcinoma. The tumour was subjected to complete surgical removal in the first instance. There was no recurrence at follow up seven months after surgery. Although fungiform papillomas are generally not premalignant, occasional malignant transformation may occur. Thus, they must be managed with the utmost cautiousness.

    Perforation of maxillary sinus mucous membrane is one of the most prevalent complications during open sinus lift surgery. Moreover, such complication can usually be managed by an absorbable membrane. As far as absorbable membranes are concerned, decellularized maxillary sinus mucous membrane, which is an extracellular matrix, can be used as a biologic scaffold and an insulating membrane in sinus lifting surgery. The decellularization process of the maxillary sinus membrane was performed by means of physical and chemical procedures (liquid nitrogen and sodium dodecyl sulfate). Then this membrane was used as a bioscaffold for culturing with adult mesenchymal stem cells, which were derived from adipose tissue. Histologic evaluation of the decellularized scaffold revealed that cells of the Schneiderian membrane were compatibly removed via SDS 1%. Moreover, the scan with electron microscope (S6N - Leo vp1450, Germany) of the scaffold indicated that the collagen fibers of the decellularized maxillary sinus membrane were intact. Furthermore, the culture studies carried out showed that this scaffold supported cell seeding. The decellularized human maxillary Schneiderian membrane has a 3D structure similar to that of the extracellular matrix of human normal tissues. As a matter of fact, it can be used as a bioscaffold to support cell seeding. Copyright © 2014 Elsevier GmbH. All rights reserved.

    2008-11-01

    To elucidate the putative role of human papillomavirus (HPV) infection in pterygium and conjunctival papilloma. Hybrid capture II (HC-II) and polymerase chain reaction (PCR) assays were performed to detect HPV in pterygium (42 samples obtained from 40 patients) and conjunctival papilloma (8 samples from 6 patients). The amount of HPV DNA was evaluated by measurement of relative light units (RLUs) on a luminometer. All papilloma samples were positive for HPV DNA by PCR and HC-II. The RLU values for specimens of recurrent and re-recurrent papilloma were markedly higher than those for specimens of primary lesions. HPV was detected by PCR in 2 of 42 (4.8%) beta-globin-positive pterygium specimens, whereas HC-II showed that HPV was negative in all pterygium samples. Our results support the hypothesis that HPV DNA is associated with the pathogenesis of conjunctival papilloma, but not pterygium. RLU measurement by HC-II may serve as a marker for evaluating the activity of HPV in conjunctival tumours.

    Sinonasal papilloma is a common benign epithelial tumor of the sinonasal tract and accounts for 0.5% to 4% of all nasal tumors. The etiology of sinonasal papilloma remains unclear, although human papilloma virus has been proposed as a major risk factor. Other etiological factors, such as anatomical variations of the nasal cavity, may be related to the pathogenesis of sinonasal papilloma, because deviated nasal septum is seen in patients with chronic rhinosinusitis. We, therefore, investigated the involvement of deviated nasal septum in the development of sinonasal papilloma. Preoperative computed tomography or magnetic resonance imaging findings of 83 patients with sinonasal papilloma were evaluated retrospectively. The side of papilloma and the direction of septal deviation showed a significant correlation. Septum deviated to the intact side in 51 of 83 patients (61.4%) and to the affected side in 18 of 83 patients (21.7%). Straight or S-shaped septum was observed in 14 of 83 patients (16.9%). Even after excluding 27 patients who underwent revision surgery and 15 patients in whom the papilloma touched the concave portion of the nasal septum, the concave side of septal deviation was associated with the development of sinonasal papilloma (p = 0.040). The high incidence of sinonasal papilloma in the concave side may reflect the consequences of the traumatic effects caused by wall shear stress of the high-velocity airflow and the increased chance of inhaling viruses and pollutants. The present study supports the causative role of human papilloma virus and toxic chemicals in the occurrence of sinonasal papilloma.

    This study aimed to clarify the local immune status in the larynx in the presence of infection or carcinogenesis associated with human papilloma virus. Cytological samples (for human papilloma virus detection) and laryngeal secretions (for immunoglobulin assessment) were obtained from 31 patients with laryngeal disease, during microscopic laryngeal surgery. On histological examination, 12 patients had squamous cell carcinoma, four had laryngeal papilloma and 15 had other benign laryngeal disease. Cytological samples were tested for human papilloma virus DNA using the Hybrid Capture 2 assay. High risk human papilloma virus DNA was detected in 25 per cent of patients (three of 12) with laryngeal cancer. Low risk human papilloma virus DNA was detected only in three laryngeal papilloma patients. The mean laryngeal secretion concentrations of immunoglobulins M, G and A and secretory immunoglobulin A in human papilloma virus DNA positive patients were more than twice those in human papilloma virus DNA negative patients. A statistically significant difference was observed between the secretory immunoglobulin A concentrations in the two groups. Patients with laryngeal cancer had higher laryngeal secretion concentrations of each immunoglobulin type, compared with patients with benign laryngeal disease. The study assessed the mean laryngeal secretion concentrations of each immunoglobulin type in the 12 laryngeal cancer patients, comparing human papilloma virus DNA positive patients (n = 3) and human papilloma virus DNA negative patients (n = 9); the mean concentrations of immunoglobulins M, G and A and secretory immunoglobulin A tended to be greater in human papilloma virus DNA positive cancer patients, compared with human papilloma virus DNA negative cancer patients. These results suggest that the local laryngeal immune response is activated by infection or carcinogenesis due to human papilloma virus. The findings strongly suggest that secretory IgA has inhibitory activity

    Full Text Available Background: Inverted papilloma (IP of the nasal cavity is a benign tumor that 0.5-4% of all nasal tumors and have been known to rarely undergo malignant transformation to squamous carcinoma an even more rarely adenocarcinoma. Synchronous association with low grade esthesioneuroblastoma (ENB has been reported in only one case report where a small sized lesion was treated with surgery alone. Here we report the first case of invasion of IP by high grade ENB with nodal metastasis that was treated with combined modality therapy.Case Presentation: A case of a 64 year-old African American gentleman presented to the otolaryngology with a three-month history of recurrent epistaxis. Imaging revealed a large right nasal cavity mass extending into the right sphenoid sinus but without intracranial extension. Surgical pathology revealed high grade ENB invading IP. An orbitofrontal craniotomy approach was used to achieve complete resection of the mass but with positive margins. Postoperative PET/CT showed nodal metastasis. The patient was then treated with adjuvant chemoradiation and remains without evidence of disease at 42 months post-treatment. We discuss the disease presentation, histopathologic features, and disease management with literature support.Conclusion: In this very rare disease presentation where two extremely rare malignancies collide, we show that aggressive management with trimodality therapy of surgery, adjuvant radiation with stereotactic radiosurgical boost, and adjuvant chemotherapy gives excellent results. Given the natural history of the disease, however, long follow up is needed to declare complete freedom from the disease.

    Choroid plexus papillomas are rare, benign tumors originating from the choroid plexus. Although generally found within the ventricular system, they can arise ectopically in the brain parenchyma or disseminate throughout the neuraxis. We sought to review recent advances in our understanding of the molecular biology and oncogenic pathways associated with this disease. A comprehensive PubMed literature review was conducted to identify manuscripts discussing the clinical, molecular, and genetic features of choroid plexus papillomas. Articles concerning diagnosis, treatment, and long-term patient outcomes were also reviewed. The introduction of atypical choroid plexus papilloma as a distinct entity has increased the need for accurate histopathologic diagnosis. Advances in immunohistochemical staining have improved our ability to differentiate choroid plexus papillomas from other intracranial tumors or metastatic lesions using combinations of key markers and mitotic indices. Recent findings have implicated Notch3 signaling, the transcription factor TWIST1, platelet-derived growth factor receptor, and the tumor necrosis factor-related apoptosis-inducing ligand pathway in choroid plexus papilloma tumorigenesis. A combination of commonly occurring chromosomal duplications and deletions has also been identified. Surgical resection remains the standard of care, although chemotherapy and radiotherapy may be considered for recurrent or metastatic lesions. While generally considered benign, these tumors possess a complex biology that sheds insight into other choroid plexus tumors, particularly malignant choroid plexus carcinomas. Improving our understanding of the molecular biology, genetics, and oncogenic pathways associated with this tumor will allow for the development of targeted therapies and improved outcomes for patients with this disease.

    Mixed squamous cell and glandular papilloma (mixed papilloma) of the lung is exceedingly rare, with only 18 cases reported in the literature. Herein, we report a case of mixed papilloma and its associated immunohistochemical and positron emission tomographic (PET) findings. A 60-year-old Japanese male with a smoking history of 40 pack-years presented with a smooth-edged pulmonary lesion in the right S5 segment on computed tomography (CT). F18-fluorodeoxyglucose (FDG) PET revealed abnormally increased FDG uptake in the mass (maximum standardized uptake value, 3.4). We performed right middle lobectomy and combined partial resection of the S8 segment. The 1.8-cm tumor that filled the enlarged lumen of the B5b was histologically diagnosed as mixed papilloma. Immunohistochemically, the pseudostratified columnar epithelium was positive for cytokeratin (CK) 5/6 and CK7. p40 positivity was predominant in the basal and squamous cells. Thyroid transcription factor-1 and carcinoembryonic antigen were negative on immunostaining. Malignant features were absent. The postoperative course has been uneventful for 3 months after the surgery. No recurrences were reported after the surgical resection of the mixed papilloma. Therefore, surgical resection may be considered the mainstay of curative treatment.

    Uroplakins are differentiation-related membrane proteins of urothelium. We compared uroplakin expression and ultrastructural localization in human normal urothelium, papilloma and papillary carcinoma. Because of high recurrence rate of these tumours, treated by transurethral resection, we investigated urothelial tumour, resection border and uninvolved urothelium. Urinary bladder samples were obtained from tumour free control subjects and patients with papilloma and papillary carcinoma. Immunohistochemical and immunoelectron labelling of uroplakins were performed. In normal human urothelium with continuous uroplakin-positive superficial cell layer uroplakins were localized to flattened mature fusiform vesicles and apical plasma membrane of umbrella cells. Diverse uroplakin expression was found in papilloma and papillary carcinoma. Three aberrant differentiation stages of urothelial cells, not found in normal urothelium, were recognized in tumours. Diverse uroplakin expression and aberrant differentiation were occasionally found in resection border and in uninvolved urothelium. We demonstrated here that uroplakin expression and localization in urothelial tumours is altered when compared to normal urothelium. In patients with papilloma and papillary carcinoma immunolabelling of uroplakins at ultrastructural level shows aberrant urothelial differentiation. It is possible that aberrant differentiation stages of urothelial cells in resection border and in uninvolved urothelium contribute to high recurrence rate.

    A number of reports have investigated the relationship between laryngeal papilloma and human papilloma virus (HPV) infection. On the other hand, it is unclear whether the HPV infection is involved in the occurrence of pharyngeal papilloma. We hypothesized that HPV infection was involved in the occurrence of pharyngeal papilloma similarly to laryngeal papilloma. To verify this hypothesis, we investigated the presence of HPV infection. Furthermore, clinical manifestations of pharyngeal papilloma, which had rarely been reported, were discussed. A male-to-female ratio, solitary or multiple occurrences, and koilocytosis were examined in cases with pharyngeal papilloma. HPV DNA was examined with unfixed surgically resected specimens of pharyngeal papilloma. A screening test by the liquid-phase hybridization method was carried out for the HPV high-risk group (16, 18, 31, 33, 35, 39, 45, 51, 56, 58, 59, and 68) and HPV low-risk group (6, 11, 42, 43, 44). As a control, 15 cases with laryngeal papilloma for which the same screening test was carried out were employed. Pharyngeal papilloma occurred as a solitary lesion more often, whereas laryngeal papilloma occurred as multiple tumors more frequently. The HPV infection rate was 0% in pharyngeal papilloma cases, which was in stark contrast with 66.7% in the HPV low-risk group in laryngeal papilloma cases. Pharyngeal papilloma occurred as a solitary lesion in females more frequently. Contrary to our hypothesis, the involvement of HPV infection was unlikely in the occurrence of pharyngeal papilloma.

    Full Text Available Choroid plexus papillomas (CPPs are usually not malignant and occur in less than 1% of brain tumors in patients of all ages. They represent 3% of childhood intracranial neoplasms with a predilection in younger ages.

    Choroid plexus papillomas (CPPs) are usually not malignant and occur in less than 1% of brain tumors in patients of all ages. They represent 3% of childhood intracranial neoplasms with a predilection in younger ages. Papillomas have an indolent course and carry a good long-term outcome if gross total surgical resection is achieved. However malignant evolution may occur, with a 10-30% incidence. Chemotherapy has been used with varied degrees of success. Most series are very small, some are only limited to case reports and cannot lead to guidelines or therapeutic recommendations.

    Full Text Available At present two prophylactic human papilloma virus (HPV vaccines are commercially available. The Tetravalent vaccine against infection with four VPH types (6, 11, 16, and 18 distributed in the national program in Colombia and the Bivalent vaccine against the VPH types 16 and 18, respectively.  The efficacy and safety of both vaccines has periodically been assessed and they have been declared efficacious and safe by the health authorities of several countries and the Global Advisory Committee on Vaccine Safety ( GACVS of the World’s Health Organization (WHO.In its report of March 2014 the GACVS analyzed the evidence of the relationship between the  Human Papillomavirus Vaccine with  >175 million of doses distributed worldwide and autoimmune diseases, particularly Multiple Sclerosis, Aluminum as adjuvant, Vasculitis caused by vaccine DNA fragments and the Complex Regional Pain Syndrome described in Japan.   The Committee ratified the strict vaccine safety control and based on a thorough examination of existing evidence, reaffirmed that the risk-benefit profile remains favorable. The case of the children of Carmen de Bolivar in Colombia has been described by several authors in other countries as "Massive Psychogenic Event", which has absolute no relationship with the vaccine but its high media dissemination resulted into disastrous consequences for the national vaccination program

    Infection with human papilloma virus (HPV) has been identified as the cause of recurrent papillomatosis and of a subgroup of squamous cell carcinomas of the head and neck. A change in prevalence of these lesions, especially for oropharyngeal carcinoma, can be expected as a consequence of the introduction of prophylactic HPV vaccines for young women, targeting the most frequent high- and low-risk HPV subtypes. Vaccination for the major low-risk HPV types has proven to be highly effective against genital warts and activity against papillomatosis can be expected. The possibilities of prophylactic HPV vaccination as well as new developments and the rationale for therapeutic vaccines are discussed on the basis of the current literature.

    To report a case of a corneal papilloma-like lesion associated with human papilloma virus type 6. A 48-year-old woman presented with a 2-year history of ocular discomfort and gradual visual deterioration in her right eye. Ophthalmic examination revealed an elevated, semitranslucent, well-defined vascularized mass approximately 4 × 2.5 mm in size localized to the right cornea. The surface of the mass appeared smooth and many small, shallow, and irregular elevations were noted. An excisional biopsy was performed. The underlying cornea was markedly thinned, and fine ramifying vasculature was also noted on the exposed corneal stroma. Typical koilocytic change was observed on the histopathologic examination. Polymerase chain reaction revealed the existence of human papilloma virus type 6 DNA. Here we describe a case of an isolated corneal papilloma-like lesion. Although the corneal extension of the limbal or the conjunctival papillomas has been commonly observed, an isolated corneal papilloma-like lesion with underlying stromal destruction has only rarely been reported.

    Full Text Available One of the most important problems in the modern world is the papilloma virus infection. As is known, this is the most widely spread sexually-transmitted infection. The human papilloma virus is responsible for the occurrence of such a terrible disease as cervical cancer, which ranks third after breast cancer and cancer of the body in the structure of oncological morbidity organs of the reproductive system and mammary glands in women. The other manifestations of the papilloma virus infection are pointed condyloma genital warts, which occur frequently both in men and in women. The only reliable method of the prevention of the papilloma virus infection is immunization. The authors present new data regarding the use of bivalent vaccine, including a new scheme of immunization for girls from nine to fourteen years old. Foreign investigations showed that the double scheme of introduction of the vaccine in young girls is as effective as a triple scheme of introduction in the category of women over 15 years of age.

The specific role of IPL structural abnormalities in the pathogenesis of FRS is yet to be ascertained. Materials and Methods: Using 3-tesla MRI scanner, this first-time study examined antipsychotic-naοve schizophrenia patients ( n = 28 (patients with FRS [FRS +]: N = 14, M: F = 7:7; and patients without FRS [FRS-]: N = 14, M: F = 7:7 in comparison with sex-, handedness-, education- and socioeconomic status-matched healthy controls ( n = 14, M: F = 7:7. The volume of IPL was measured using a three-dimensional, interactive, semi-automated analysis, with good inter-rater reliability. Results: FRS + patients showed significant volume deficit in right IPL in comparison with healthy controls (F = 4.0; P=.028 after controlling for the potential confounding effects of age, sex and intracranial volume. Conclusions: Right IPL volume deficit in FRS+patients adds further support to the Frith′s model of FRS in schizophrenia.

    Controversy exists regarding the pathogenesis of inverted papilloma as it relates to the involvement of human papillomavirus (HPV). The purpose of this report is to describe the prevalence of HPV in nondysplastic, "early inverted papilloma" and to summarize HPV detection rates in the general population and in other HPV related neoplasia. This case series report characterizes consecutive inverted papilloma patients from January 2005 to August 2012 with regard to smoking history, dysplasia, and HPV detection rates. Presence or absence of low/high risk HPV was determined by standardized in situ hybridization DNA probes. Medline literature review was performed to determine the prevalence of HPV in inverted papilloma without moderate or severe dysplasia. Thirty-six consecutive patients were identified with an average age of 63.6 (range, 40-84) years; gender: 23 men, 13 women. More than half (55%) were active or former smokers (14% active and 41% former). High/low risk HPV was present in 1 in 36 (2.7%) patients and 1 in 36 (2.7%) had mild dysplasia. In the literature review: (1) HPV was detected in 16.4% of inverted papilloma without dysplasia; (2) oral cavity HPV detection was 4.2% to 11.4% in the normal population; and (3) HPV was normally detected in 85% to 95% of HPV-related neoplasia. Given histological features of inverted papilloma and comparatively low detection rates of HPV in inverted papilloma without dysplasia (2.7%), as well as the summary of the world literature, HPV is not related to the initial pathogenesis of inverted papilloma or inverted papilloma's tendency to persist or recur. It is postulated that since inverted papilloma is more an inflammatory polyp, it is susceptible to secondary HPV infection because of its metaplasia. Tobacco and other causes of respiratory epithelium remodeling are more plausible explanations for the initial tissue transformation to inverted papilloma. © 2014 ARS-AAOA, LLC.

    2016-03-01

    Full Text Available Background: Sinuslift is meanwhile an established method of bone augmentation in the posterior maxilla. Aim of the study was to evaluate the significance of intraoperative Schneiderian membrane perforations during maxillary sinus floor elevation surgery using autogenous bone harvested from two different donor sites using a Safescraper device on the success rate, graft survival and implant integration.Methods: The investigators conducted a retrospective cohort study at the Department of Oral and Maxillofacial Surgery of Military Hospital Ulm composed of patients with severe maxillary atrophy who underwent sinus augmentation from January 2011 until December 2011. Ninety-nine consecutive patients (89 men, 10 women with a mean age of 43.1 years underwent sinus graft procedures in a 2-stage procedure using the lateral wall approach, as described by Tatum (1986. Data on patient age, smoking status, donor site and surgical complications were recorded and the relationship between Schneiderian membrane perforation and complication rate was evaluated. Dental implants were inserted 4 months after grafting.Results: A total of 105 sinus lift procedures were performed in 99 patients. Sixty-one patients (61.6% underwent sinus elevation with autogenous bone from the buccal sinus wall, while 38 patients (38.4% bone harvesting from the iliac crest. Intraoperative perforation of the Schneiderian membrane was observed in 11 of the 105 sinuses (10.4%. These perforations resulted in 4 (36.3% of the cases in major postoperative complications accompanied by swelling and wound infection. Membrane perforations were slightly associated with the appearance of postoperative complications (p=0.0762. In 2.4% of all cases, regarding 2 patients the final rehabilitation with dental implants was not possible because of extensive bone resorption. Conclusion: Intraoperative complications performing sinus augmentation may lead to postoperative complications. With careful clinical

    Full Text Available Recurrent respiratory papillomatosis is a relatively uncommon disease that presents clinically with symptoms ranging from hoarseness to severe dyspnea. Human papilloma virus types 6 and 11 are important in the etiology of papillomas and are most probably transmitted from mother to child during birth. Although spontaneous remission is frequent, pulmonary spread and/or malignant transformation resulting in death has been reported. CO2 laser evaporation of papillomas and adjuvant drug therapy using lymphoblastoid interferon-alpha are the most common treatments. However, several other treatments have been tried, with varying success. In the present report, a case of laryngeal papillomatosis presenting with chronic stridor and delayed speech is described.

    Papilloma frequently develops as a benign tumor of the head and neck area, but its potential for malignant transformation has yet to be studied. This study aims to provide basic information for papillomas using the immunohistochemical staining of matrix metalloproteinase 2 (MMP-2) and human papilloma virus (HPV) 16 and 18. To evaluate the malignant transformation of papillomas, the selected tissue samples were serially diagnosed with pre-cancerous papilloma (with epithelial dysplasia, pseudo-epitheliomatous hyperplasia) or malignant lesion (squamous cell carcinoma, SCC) after the first diagnosis (squamous papilloma, inverted papilloma). The selected tissues were stained with an antibody to MMP-2 and HPV 16-E7, HPV 18-L1. A statistical analysis was performed according to each transformation step. The epithelial layer of papilloma and pre-cancerous papilloma lesions had a similar MMP-2 expression, but that of the malignant lesion had a significantly increased MMP-2 expression. HPV 16 and 18 infection rates were 28.6%, 33.3% and 63.6% in papillomas, pre-cancerous papilloma lesions, and SCC. A relatively high MMP-2 expression and HPV 16 or 18 infection of papillomas may be associated with early events in the multistep processes of malignant transformation of papillomas.

Malignant degeneration into squamous cell carcinoma is quite common, although curative approaches vary a lot in modern literature.Case report: We report a case of a 66-year-old male patient with the coexistence of multiple squamous cell papilloma and carcinoma in the upper trachea with severe airway obstruction that was diagnosed through bronchoscopy and treated by performing an urgent tracheostomy, followed by concurrent chemotherapy and radiotherapy. There was no evidence of recurrence after a 12-month follow-up period.Conclusion: This study underlines the diagnostic and therapeutic value of bronchoscopy as well as multimodality palliative treatment in such cases. To the best of our knowledge, this is the first study to describe an immediate treatment protocol with tracheostomy and concurrent chemotherapy/radiotherapy in a patient with squamous cell tracheal papilloma and carcinoma

    Full Text Available The objective of this study was to evaluate the incidence of genital human papilloma virus (HPV infection and cervical intra-epithelial lesions in transplanted patients. Cervical Papanicolaou (Pap smear/HPV test and colposcopic examinations were performed in 58 patients who were candidates for renal transplant surgery; these tests were repeated one year later. Their age range was 26-53 years (mean, 37.2 years. Hypertension was the most common cause of renal insufficiency (34.4%, while in 41.4% of the patients, the causative pathology was unknown. In 24.1% of the patients, there was no history of dialysis, i.e. they had pre-emptive transplantation. The mean duration of marriage (years since first intercourse was 16.2 years (range, 1-35. Coitus interruptus was the most common contraceptive method used (37.9%, followed by tubal ligation and condom (10.3% and 6.9%, respectively. All patients had negative Pap tests and normal gynecologic exam before undergoing transplantation. The Pap test remained normal after transplant surgery, although the HPV test became positive in four patients (6.9%. There were five cases of white epithelium on colposcopy, but biopsy showed normal metaplasia. Two cases of extensive anogenital warts were treated by CO 2 laser, and one patient had recurrent warts, which responded well to second laser surgery. None of the study patients had squamous intra-epithelial lesions (SIL or vulvar intra-epithelial neoplasia. Our study suggests that screening with HPV and Pap test should be performed before transplant surgery and should be repeated at regular intervals in order to avoid irreversible situations such as high-grade SILs, which are difficult to treat. Avoiding high-risk sexual relations in this group of patients is highly recommended.

    Intraductal papillomas are the most common subtype of papillomas, which are benign neoplasms of the breast. An intraductal papillomas is usually found as a solitary mass which originates in the major duct of the breast. Intraductal papilloma cases are frequently presented as nipple discharge and most commonly occur in individuals between the ages of 30 and 55 years. Few reports exist regarding cases of intraductal papillomas in children. We report a case of an intraductal papilloma, with imaging findings, which occurred in the breast of an 11-years old girl and presented as bloody nipple discharge.

    Breast diseases are rare in childhood and adolescence, most lesions being fibroadenomas and papillomas. We report the case of an 11-year old girl with a complex breast lesion with hybrid features of fibroadenoma and intraductal papilloma with an early recurrence. Microscopically, the lesion was composed of dilated ducts showing intraluminal papillary projections with small to broad fibrovascular stalks. The typical leaf-like appearance of fibroadenoma was determined by the presence at the periphery of ducts compressed and distorted by the prominent stromal component. Despite its florid epithelial hyperplasia and mild cytological atypia (more evident in the relapse), immunohistochemical staining for p63 and smooth muscle actin highlighted a continuum outer myoepithelial layer, confirming the non-invasive appearance of the lesion. Two pathogenetic links have been hypothesized: one is based on the morphological continuum between these two entities, which may represent different evolutive stages in the same lesion; the other is based on epithelial/mesenchymal interactions. The possible malignant transformation of such complex lesion is also discussed, along with its differential diagnoses. The relevance of this case lies in its rarity, as well as in the therapeutic strategies related to its biological potential and to the necessity of a conservative treatment, due to the young age of the patient.

    Identifying effective treatment for papillomatosis is limited by a lack of animal models, and there is currently no preclinical model for testing potential therapeutic agents. We hypothesized that xenografting of papilloma may facilitate in vivo drug testing to identify novel treatment options. A biopsy of fresh tracheal papilloma was xenografted into a NOD-scid-IL2Rgamma(null) (NSG) mouse. The xenograft began growing after 5 weeks and was serially passaged over multiple generations. Each generation showed a consistent log-growth pattern, and in all xenografts, the presence of the human papillomavirus (HPV) genome was confirmed by polymerase chain reaction (PCR). Histopathologic analysis demonstrated that the squamous architecture of the original papilloma was maintained in each generation. In vivo drug testing with bevacizumab (5 mg/kg i.p. twice weekly for 3 weeks) showed a dramatic therapeutic response compared to saline control. We report here the first successful case of serial xenografting of a tracheal papilloma in vivo with a therapeutic response observed with drug testing. In severely immunocompromised mice, the HPV genome and squamous differentiation of the papilloma can be maintained for multiple generations. This is a feasible approach to identify therapeutic agents in the treatment of recurrent respiratory papillomatosis. © The Author(s) 2014.

  9. Congenital papillomas and papillomatoses associated with the Human Papilloma Virus (HPV: report on 5 cases

    Directory of Open Access Journals (Sweden)

    Eliane Pedra Dias

    Full Text Available The authors present a study of five cases of vulvar congenital papillomas and papillomatoses in stillborns and neonates dead upon birth. The studied material was collected from five necropsies. The histopathological evaluation showed hyperkeratosis, acanthosis, papillomatosis, perinuclear haloes, and nuclear abnormalities. In three of the cases, the electron microscopy identified nuclear and cytoplasmatic viral particles ranging from 40 to 60 nm in size, compatible with HPV. The immunohistochemical study of those lesions showed nuclear and cytoplasmatic positivity. The authors concluded that the presence of viral particles suggestive of HPV added to the immunopositivity indicated the possibility of viral infection.

    Full Text Available Solitary tracheobronchial papilloma (STBP is a rare benign tumor that primarily involves the tracheobronchial tree. Human papilloma virus (HPV infection is associated with dysplasia and a high risk of carcinoma in these lesions. The cytomorphology of STBP is not well established in the literature. Our aim is to characterize the cytomorphologic features of STBP, with histologic correlation in a series of 6 patients - 4 males and 2 females - with a mean age of 67 years (range, 53-88 years. There were 5 biopsy-proven squamous papillomas and 1 glandular papilloma. On surgical biopsy, squamous papillomas exhibited cytological atypia (4 graded mild and 1 graded moderate with focal severe dysplasia, surface erosion, and inflammation. Cytology specimens available for review included a combination of 4 fine-needle aspirations (FNAs, 2 bronchoalveolar lavages and 2 (of 3 bronchial brushings. Cytologic findings associated with squamous papillomas included atypical squamous cells and rare squamous cell resembling koilocyte in 1 bronchial brushing. Sheets of squamous cells were identified in another specimen. Several cases had a prominent background of acute inflammation, and candida was present in 1 specimen. HPV in-situ hybridization was positive in 1 case and negative in 2 cases. A p16 immunocytochemical stain performed on 1 cell block was negative. In conclusion, although STBP is a rare neoplasm, these cases may be encountered in respiratory cytology samples. FNA of papillomas yields fewer lesional cells compared to exfoliative samples. These lesions may be mistaken in cytology specimens for squamous cell carcinoma, squamous-lined cavitary lesions, an infectious (fungal process, reactive squamous metaplasia, or oral contamination.

    2011-11-01

    Human Papilloma Virus (HPV) is becoming a menace worldwide, especially to the developing world, due to its involvement in a variety of malignancies, with cervical cancer being the most important and prevalent. There are many HPV types; HPV 16/18 are the most carcinogenic but few others are also characterized as high-risk (HR). They can cause a variety of low- or high-grade cellular abnormalities, most frequently detected in a routine Pap test. Most infections clear within 2 years, however, a minority persists and potentially could progress to cervical cancer. Molecular tests detecting HPV DNA, RNA or proteins are now being available either commercially or in-house developed. DNA detection is nowadays an established tool for diagnosis and monitoring of HPV-related disease, however, there is lack of a reference method and standardization with reference materials. The various available test formats create confusion on which molecular test to choose and what are its limitations. Therefore, the need for lab accreditation and participation in proficiency testing has to be stressed. Novel HPV biomarkers (RNA, protein etc.) are now intensively examined for their inclusion as adjunct tools. Recently, developed prophylactic vaccines for HPV 16/18 have already proven safe and efficient and raise high expectations for the complete eradication of these types in the future.

    The aim of our study was to determine the prevalence and the natural course of anogenital human papilloma virus (HPV) infections in girls prior to coitarche attending an outpatient gynecological unit. Specimens were taken from the anogenital region of 114 unselected 4-15 year old girls who were referred consecutively for various gynecological problems. Four girls were excluded because of sexual abuse. Low-risk HPV-deoxyribonucleic acid (DNA) was detected in 4 girls (3.6%) and high-risk HPV DNA in 15 children (13.6%). Two girls testing positive for HPV DNA had clinical apparent warts. After 1 year, 2 children had persistent high-risk HPV DNA, and in 1 case we found a switch from high-risk to low-risk HPV DNA. Subclinical genital low- and high-risk HPV infections are common in girls without any history of sexual abuse or sexual activity. We found persistence of genital HPV infection in children, which could be a reservoir for HPV-associated diseases later in life.

    2010-01-01

    Full Text Available Background: Intraductal papilloma is characterized by proliferation of epithelial and myoepithelial cells overlying fibro-vascular stalks creating an arborescent structure within the lumen of duct. Some times multiple papillomas with florid proliferation of epithelium may be confused with malignancy. A case of multiple intraductal papillomas of breast with ulceration of overlying skin and large lump leading to clinical diagnosis of malignancy is documented here. Case Report: A 45-year-old female presented with ulcerated mass of six months duration in the left breast. On examination, a firm, immobile lump of 8× 10 cm in size involving nipple with excoriation of surrounding skin and serosanguinous discharge from nipple was present. There was no axillary lymphadenopathy. No family history of carcinoma breast was present. Fine needle aspiration smears showed benign cellular changes with apocrine metaplasia. Biopsy from an area adjacent to nipple showed intraductal papilloma. Simple mastectomy showed lobulated dirty white mass with well circumscribed nodules below the nipple and areola. On histology with immunohistochemistry a diagnosis of multiple intraductal papillomas was made. Patient is on regular follow-up and doing well. Conclusion: The case highlights the problem in differentiating marked papillomatosis from a malignant lesion of breast and importance of biopsy with immunohistochemistry in such cases for proper management.

    Papillomas of the conjunctival surface in people can be of viral or nonviral origin and are found in high association with human papillomavirus. Canine conjunctival papillomas are seldom described, and published accounts have mostly been associated with canine oral papillomavirus infection. Here, we describe conjunctival squamous papillomas that do not express papillomavirus proteins and compare them with papillomavirus-associated conjunctival papillomas. Conjunctival squamous papillomas presented a distinct histopathologic profile and lacked the cytopathic effects seen in viral papillomas. They appeared as exophytic, papilliferous, pedunculated lesions with delicate fronds and angular terminal margins. Squamous papillomas presented with a delicate fibrovascular core and were associated both clinically and grossly with a feeder vessel. Pigmentation was variable within the epithelium and stroma of these lesions, and inflammatory infiltrates were characteristically minimal. Conjunctival squamous papillomas resembled squamous papillomas of the skin; however, they lacked significant hyperkeratosis. Compared with conjunctival viral papillomas, these masses occurred in older dogs and were smaller and solitary. Furthermore, polymerase chain reaction and immunohistochemistry failed to demonstrate papillomavirus genetic material and antigens in conjunctival squamous papillomas. Both viral and nonviral conjunctival papillomas were considered benign. © The Author(s) 2014.

    Full Text Available Varicocele recurrence is one of the most common complications associated with varicocele repair. A systematic review was performed to evaluate varicocele recurrence rates, anatomic causes of recurrence, and methods of management of recurrent varicoceles. The PubMed database was evaluated using keywords "recurrent" and "varicocele" as well as MESH criteria "recurrent" and "varicocele." Articles were not included that were not in English, represented single case reports, focused solely on subclinical varicocele, or focused solely on a pediatric population (age <18. Rates of recurrence vary with the technique of varicocele repair from 0% to 35%. Anatomy of recurrence can be defined by venography. Management of varicocele recurrence can be surgical or via embolization.

    The purpose of this study was to investigate roles of human papillomavirus (HPV) infection and stathmin in sinonasal inverted papilloma (SNIP). HPV DNA detection was performed by the fluorescence-based polymerase chain reaction (PCR) method. Stathmin protein expression was investigated by the immunohistochemistry method and mRNA expression of stathmin, Kif2a, and cyclin D1 were assessed by real-time PCR in SNIP and control subjects. The positive rate of HPV DNA detected in SNIP was about 53.6% (15 of 28). Recurrent cases showed a higher rate of HPV infection compared with initial cases and higher Krouse stage (T3 + T4) cases showed higher rate of HPV infection than lower Krouse stage (T1 + T2) cases. Stronger expression of stathmin, Kif2a, and cyclin D1 were observed in SNIP, especially HPV(+) SNIP. HPV infection was closely associated with recurrence and progression of SNIP. Stathmin is a valuable prognostic marker and could be considered as a therapeutic target in patients with SNIP. © 2015 Wiley Periodicals, Inc.

    This paper is a report of a study of women's awareness of the human papilloma virus and related health problems. Cervical cancer is an important cause of mortality, making up approximately 12% of all cancers in women. Awareness on the part of carriers of human papilloma virus is crucial in preventing transmission of the infection and protecting against cervical cancer. The study was performed as a cross-sectional descriptive study. The study consists of 79 human papilloma virus-positive women who had not been diagnosed with cervical cancer and 150 women who had not been diagnosed with human papilloma virus. Data were collected via questionnaires between November 2007 and April 2008. Percentages and chi-square test were used. A significantly higher percentage of women with positive human papilloma virus knew the definition of human papilloma virus, the fact that it is transmitted via sexual contact and that it can lead to cervical cancer than did women with negative human papilloma virus. It was established that approximately half the women with positive human papilloma virus presented at the hospital with a genital wart. None of the women knew that a Pap smear test was a necessary tool in the prevention of cervical cancer. Women with positive human papilloma virus have insufficient knowledge of human papilloma virus, sexually transmitted diseases, the health risks associated with human papilloma virus and the means of preventing these risks. It is therefore necessary to evaluate the education of health workers, and especially of nurses, on human papilloma virus and its prevention. © 2011 Blackwell Publishing Ltd.

    A 4-yr-old male diamond python (Morelia spilota spilota) was evaluated for multiple black papillated exophytic skin proliferations and signs of pneumonia. The histopathologic structure of the skin biopsy specimens led to the diagnosis of a benign papilloma-like neoplasia. In this case, papillomavirus DNA could be amplified from a biopsy sample with a broad range polymerase chain reaction. Nested pan-herpes polymerase chain reaction was negative, and herpesvirus inclusion bodies were not found. Because of the histologically benign nature of the papilloma, the skin proliferations were left untreated. Ten mo after the first presentation, the skin lesions had regressed almost completely; 34 mo later, only scars from the biopsies were left.

    Inclusions of ectopic breast tissue in axillary lymph nodes are reported very infrequently and typically are only identified microscopically as an incidental finding. Furthermore the development of a benign proliferative lesion in the form of an intraductal papilloma from intranodal ectopic breast tissue is an extremely rare phenomenon with only three previous cases reported. This report describes an unusual and rare case of an intraductal papilloma arising in an axillary lymph node of a patient known to have the human immunodeficiency virus. A 40-year-old Black African woman underwent excision of an enlarged palpable axillary lymph node. In the preceding 7 years she had received at least six separate surgical excisions to her ipsilateral breast for papillomatosis. The last surgical intervention was performed 1 year prior to presentation with an enlarged axillary lymph node. Histological examination of her axillary lymph node revealed a papillomatous proliferative epithelial lesion within an apparent encompassing duct, resembling a mammary intraductal papilloma. In the surrounding lymphoid tissue small groups of duct-like structures were additionally noted. Immunostaining with a panel of myoepithelial markers in conjunction with oestrogen receptor produced a mixed heterogeneous staining pattern in both the papillomatous lesion and the peripheral duct-like structures. This confirmed the diagnosis of a benign intraductal papilloma within an axillary lymph node, considered to have arisen from ectopic breast tissue. This case demonstrates that intranodal ectopic breast tissue has the potential to undergo benign proliferative change albeit extremely rarely. Therefore this possibility must be considered to ensure the correct diagnosis is made. In addition, to the best of our knowledge, this is the first case report which has described recurrent intraductal papillomas and the subsequent development of an intraductal papilloma within an ipsilateral axillary lymph node, in

    Denture hyperplasia is a reactive lesion of the oral mucosa, usually associated to an ill-fitting denture. This lesion is easily diagnosed and in some cases distinct microscopic variations such as osseous, oncocytic and squamous metaplasia may be found. These metaplastic alterations probably are associated with the lymphocytic infiltrate usually present in denture hyperplasia. We present a case of denture hyperplasia containing salivary gland tissue with ductal alterations mimicking an oral inverted ductal papilloma.

    A five-year-old girl developed hoarseness with gradual worsening at the age of eight months. Three months later, she underwent bronchoscopy in which papillomas in the vocal cords, larynx and trachea were observed. Because of serious bronchospasm crises and respiratory failure, she needed several hospitalizations, definitive tracheostomy and multiple endoscopic procedures for papilloma excision. The most recent chest radiography (Figure A) and computed tomography (CT) scans (Figures B and C) showed a nodule inside the trachea and multiple pulmonary nodules, cysts and consolidations. The anatomopathological findings from curettage of the lesions revealed benign squamous-cell papillomas. Recurrent respiratory papillomatosis (RRP) is directly related to the human papillomavirus (HPV). Its spread to the lower airways is uncommon, with involvement of trachea and/or proximal bronchi in 5% of the patients, and extension to the lungs in only 1% of the cases. (author)

    There has been a recent increase in the incidence of oropharyngeal cancer (OPC) associated with high-risk human papilloma virus (HPV) infection. We investigated the incidence of esophageal papilloma and the presence of high-risk HPV infection. This is a cross-sectional study conducted at a County teaching hospital. Patients with esophageal papilloma between January 2000 and December 2013 were identified. Patients with sufficient specimens were tested for the HPV virus. Sixty patients with esophageal papilloma lesions were identified from 2000 to 2013. (31 males, age 51 ± 13 years). The incidence was 0.13% in 2000 and increased to 0.57% in 2013 (P papilloma that was more than 5 mm in size, and 20% had multiple lesions. The papilloma was located in the distal esophagus in 35 (58.3%) patients, mid esophagus in 17 (28.3%) patients, and proximal in 8 (13.3%) patients. Three (5%) patients had associated OPC, and 9 (47.4%) of the 19 patients tested were positive for high-risk HPV serotype 16. The incidence of esophageal papilloma has increased by fourfolds over the past 14 years. About half of the tested patients demonstrated high risk HPV. This may suggest a potential growing risk for esophageal squamous cell cancer in the future. © 2016 International Society for Diseases of the Esophagus.

    ABSTRACT Gingival overgrowths can occur due to various factors, such as inflammation, or rarely without a reason and are significant in periodontology. Here, we describe the diagnosis and treatment of a 33-year old female with a papilloma-like atypical enlargement of the gingiva attached to the molar vestibular region of her lower jaw. After the patient’s medical history was taken and the clinical examination done, the enlargement was surgically removed with a Nd:YAG laser and evaluated histopathologically. There was an inflamed, oedematous and vascularized stroma with a thick spongy squamous epithelium layer. After six months, there were no problems at the surgical area and recurrence was not observed.

    The status of human papillomavirus (HPV) infection in urothelial inverted papilloma was examined in the present study. Formalin-fixed and paraffin-embedded tissues from eight cases of inverted papilloma of the bladder were studied. The presence of HPV-DNA was examined by modified GP5/6+PCR using archival tissue sections by microdissection. HPV genotype was determined with a Hybri-Max HPV genotyping kit. Immunohistochemical analysis for p16-INK4a, mcm7, HPV-E4, and L1, and in situ hybridization for the HPV genome were performed. HPV was detected in seven of eight cases (87.5%) of inverted papilloma. Three cases were diagnosed as inverted papilloma with atypia, while the remaining five were typical cases. HPV-18 was detected in two cases, including one inverted papilloma with atypia, and HPV-16 was detected in four cases, including one inverted papilloma with atypia. Multiple HPV type infection was detected in one typical case and one atypical case. High-risk HPV was present in all HPV-positive cases. Cellular proteins, p16-INK4a and mcm7, which are surrogate markers for HPV-E7 expression, were detected in all HPV-positive cases, and their levels were higher in inverted papilloma with atypia than in typical cases. In contrast, HPV-E4 and L1, which are markers for HPV propagation, were observed in some parts of the typical inverted papilloma tissue. High-risk HPV infection may be one of the causes of urothelial inverted papilloma, and inverted papilloma with atypia may have malignant potential. 2010 Wiley-Liss, Inc.

    Full Text Available Introduction. Inverted papilloma (IP is an uncommon, benign yet aggressive neoplasm characterised by high recurrence rates and tendency towards malignant transformation. The majority of IP cases originate in the ethmoid region, lateral wall of the nasal fossa, and maxillary sinus. The authors report a case of an IP originating primarily from the nasolacrimal duct (NLD. Case. A 69-year-old Caucasian gentleman presented with a lump in his right medial canthal region, epiphora, and discharge bilaterally. Radiological investigation revealed a well-defined, heterogeneous mass within the proximal NLD eroding the bony canal, protruding into the middle meatus and into the right orbit. The tumour was excised en bloc utilizing a combined external and endoscopic approach based on its location. Histology revealed hyperplastic ribbons of basement membrane-enclosed epithelium growing endophytically into the underlying stroma with no evidence of invasive malignancy. The patient made an uneventful recovery with unchanged visual acuity and normal extraocular movements. Conclusion. The case demonstrates variability within the sinonasal tract that IP can develop and the individuality of each case necessitating tailored operative techniques for complete excision whilst minimising recurrence rates. We also present a combined endoscopic approach for the en bloc resection of a NLD IP with no clinical recurrence at 15-month follow-up.

    Full Text Available It is widely accepted that the Epstein-Barr virus is etiologically associated with the development of nasopharyngeal carcinoma. The human papillomavirus is also associated with inverted papilloma. We used the polymerase chain reaction technique to detect both viruses in both types of tumors. Flow cytometry was also used to study the DNA pattern and proliferative behavior of the tumors in relation to the viruses. EBV was detected in 13/20 (65% of NPC specimens, and in none of IP (n = 10 or control specimens (n = 10. This indicates the contribution of EBV as an etiologic factor in NPC. Five cases of NPC (25% were positive for HPV 16, two of them were EBV positive. Four HPV 16 positive cases were found among cases with inverted papilloma, but none among the control cases. Flow cytometry revealed that all NPC, IP, and control samples were diploid except one aneuploid NPC sample. Proliferative capacity (PC of primary tumors was predictive of tumor recurrence in NPC. Using 13.6% as a cut-off point for PC, we were able to discriminate between high risk and low risk groups with 100% sensitivity and 86% specificity. PC can be used as a baseline prognostic parameter in NPC, making it possible to modify courses of treatment in an attempt to inhibit tumor recurrence.

    Vulvovaginitis (VV) is one of the most commonly encountered problems by a gynecologist. Many women frequently self-treat with over-the-counter medications, and may present to their health-care provider after a treatment failure. Vulvovaginal candidiasis, bacterial vaginosis, and trichomoniasis may occur as discreet or recurrent episodes, and have been associated with significant treatment cost and morbidity. We present an update on diagnostic capabilities and treatment modalities that address recurrent and refractory episodes of VV.

    Breast papilloma is a term that describes an intraductal papillary configuration of the mammary epithelium on macroscopic or microscopic examination. It includes solitary intraductal papillomas, multiple papillomas, papillomatosis, and juvenile papillomatosis (JP). Recent advances in mammary ductoscopy (MD) have raised new possibilities in the diagnosis and treatment of breast papillomas. This technique represents an important diagnostic adjunct in patients with pathological nipple discharge (PND) by allowing direct visualisation and biopsy of intraductal lesions and guiding duct excision surgery. Treatment of breast papillomas often entails surgical duct excision for symptomatic relief and histopathological examination. Recently, more conservative approach has been adapted. MD-assisted microdochectomy should be considered the procedure of choice for a papilloma-related single duct discharge. Furthermore, there is increasing evidence that MD has the potential to reduce the number of duct excision procedures and minimise the extent of surgical resection. Imaging-guided vacuum-assisted core biopsy can be diagnostic and therapeutic for papillomas seen on mammography and/or ultrasound. Patients with multiple papillomas do have an increased risk of developing cancer and should be kept under annual review with regular mammography (preferably digital mammography) if treated conservatively. Magnetic resonance (MR) can be also used in surveillance in view of its high sensitivity. Because the risk is small, long term and affects both breasts, long-term follow-up is more appropriate than prophylactic mastectomy. Patients who prove to have solitary duct papilloma have insufficient increase in the risk of subsequent malignancy to justify routine follow-up. PMID:16417642

    Recurrent respiratory papillomatosis (RRP) is a benign condition of the mucosa of the upper aerodigestive tract. It is characterised by recurrent papillomatous lesions and is associated with human papillomavirus (HPV). Frequent recurrence and rapid papilloma growth are common and in part responsible for the onset of potentially life-threatening symptoms. Most patients afflicted by the condition will require repeated surgical treatments to maintain their airway, and these may result in scarring and voice problems. Photodynamic therapy introduces a light-sensitising agent, which is administered either orally or by injection. This substance (called a photo-sensitiser) is selectively retained in hyperplastic and neoplastic tissue, including papilloma. It is then activated by light of a specific wavelength and may be used as a sole or adjuvant treatment for RRP. To assess the effects of photodynamic therapy in the management of recurrent respiratory papillomatosis (RRP) in children and adults. We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the search was 27 January 2014. Randomised controlled trials utilising photodynamic therapy as sole or adjuvant therapy in participants of any age with proven RRP versus control intervention. Primary outcome measures were symptom improvement (respiratory distress/dyspnoea and voice quality), quality of life improvement and recurrence-free interval. Secondary outcomes included reduction in the frequency of surgical intervention, reduction in disease volume and adverse effects of treatment.   We used the standard methodological procedures expected by The Cochrane Collaboration.

    An 11-year-old girl had four episodes of fever in a year, lasting 7-10 days and associated with headache and neck stiffness. She had a long history of recurrent urticaria, usually preceding the fevers. There was also a history of vague pains in her knees and in the small joints of her hands. Her serum C-reactive protein was moderately raised at 41 g/L (normal <8). Her rheumatologist felt the association of recurrent fevers that lasted 7 or more days with headaches, arthralgia and recurrent urticaria suggested one of the periodic fever syndromes. Genetic testing confirmed she had a gene mutation consistent with one of tumour necrosis factor receptor-associated periodic syndrome.

    2012-02-01

    There is considerable debate within the literature about the significance of human papilloma virus in head and neck squamous cell carcinoma, and its potential influence on the prevention, diagnosis, grading, treatment and prognosis of these cancers. Cigarette smoking and alcohol consumption have traditionally been cited as the main risk factors for head and neck cancers. However, human papilloma virus, normally associated with cervical and other genital carcinomas, has emerged as a possible key aetiological factor in head and neck squamous cell carcinoma, especially oropharyngeal cancers. These cancers pose a significant financial burden on health resources and are increasing in incidence. The recent introduction of vaccines targeted against human papilloma virus types 16 and 18, to prevent cervical cancer, has highlighted the need for ongoing research into the importance of human papilloma virus in head and neck squamous cell carcinoma.

    Full Text Available Oral squamous papilloma is a benign proliferation of the stratified squamous epithelium, which results in a papillary or verrucous exophytic mass induced by human papilloma virus (HPV. These oral mucosa lesions are most often asymptomatic and have small progression. Laser assisted surgery is common nowadays with several advantages including successful hemostasis, devoid of sutures, wound sterilization and minimal post-operative pain and edema. The aim of this report is to present the oral squamous papilloma in a pediatric patient and its treatment with soft tissue laser. The lesion was excised with diode laser and the healing was uneventful in follow-up visit after one year. Oral squamous papillomas can be found in child′s oral cavity and laser dentistry can be used by dental clinicians to treat these kinds of oral lesions and should be considered as an alternative to conventional surgery.

    Full Text Available Our goal was to assess the value of surgical excision of benign papillomas of the breast diagnosed on percutaneous core biopsy by determining the frequency of upgrade to malignancies and high risk lesions on a final surgical pathology. We reviewed 67 patients who had biopsies yielding benign papilloma and underwent subsequent surgical excision. Surgical pathology of the excised lesions was compared with initial core biopsy pathology results. 54 patients had concordant benign core and excisional pathology. Cancer (ductal carcinoma in situ and invasive ductal carcinoma was diagnosed in five (7% patients. Surgery revealed high-risk lesions in 8 (12% patients, including atypical ductal hyperplasia, atypical lobular hyperplasia, and lobular carcinoma in situ. Cancer and high risk lesions accounted for 13 (19% upstaging events from benign papilloma diagnosis. Our data suggests that surgical excision is warranted with core pathology of benign papilloma.

    Background: Intraductal papillomas often present as small, smooth masses, dilated ducts or microcalcifications at mammography and as smooth, hypoechoic masses at sonography. At magnetic resonance imaging (MRI), intraductal papillomas often present as small smooth masses, however, often with strong enhancement with type 2 or 3 time intensity curves. The result of the MR analysis is therefore not infrequently inconclusive in order to characterize the mass as benign or malignant. Purpose: To characterize the appearance of intraductal papillomas of the breast at MRI, and determine whether the application of diagnostic rules described in literature could contribute to correctly classifying the lesions as benign. Material and Methods: Twenty patients with histologically proven intraductal papillomas were included. Two radiologists independently reviewed the MR images of the breast. The BI-RADS nomenclature was used to describe morphology and contrast-enhancement kinetics. Interobserver agreement in the interpretation of the MR images by the two investigators was performed. Kappa coefficient was calculated as index for the level of agreement. Subsequently, three sets of diagnostic rules, including the Goettinger score described by Fischer and the interpretation flowcharts according to Kinkel and to Tozaki were applied to characterize whether a biopsy should be recommended or not. Results: All papillomas presented as masses on dynamic contrast-enhanced MRI. Only five papillomas showed a round, oval, or lobulated shape combined with smooth margins and continuous rise of the time intensity curve. Using the Goettinger score, biopsy would be recommended in 16 patients. Based on the interpretation flowcharts of Kinkel and of Tozaki, an additional 13 and 10 papillomas, respectively, were correctly classified as benign. Dilated ducts were visible in 10 patients. The interobserver agreement was good or excellent for all included variables. Conclusion: Including systematic analysis

    Inverted papillomas (IP) inserted in the frontal sinus and/or recess may be treated by using an endoscopic endonasal or an external approach. There are still few data available on this uncommon localization of IPs. To report our experience in the management of IP of the frontal drainage pathway, to describe a previously unreported specific complication of this surgery, and to discuss the optimal surgical strategy. A retrospective study of the patients at a tertiary care center between 2004 and 2014 who were operated on for an IP with an insertion in the frontal recess and/or the frontal sinus. Clinical charts were reviewed for demographics, clinical presentation, imaging findings, surgical treatment, and outcome. Twenty-seven patients were included. Patients were operated on by using a purely endoscopic approach (Draf procedure; n = 14 [51.9%]) when the IP was inserted in the frontal recess and/or the frontal sinus infundibulum (with a nasoseptal-septoturbinal flap placed on the exposed bone in four patients), or by using a combined endoscopic and open approach (osteoplastic flap procedure; n = 13 [48.1%]) when the IP invaded the frontal sinus beyond the infundibulum. There were two recurrences (7.4%), with a mean follow-up of 40 months (range, 9-123 months). During follow-up, single or multiple iatrogenic frontal mucoceles were observed in 10 patients (37%), with a mean delay of 60 months (range, 27-89 months). These mucoceles occurred both after using endoscopic (n = 3) or combined (n = 7) approaches, and required a surgical treatment in eight patients. No postoperative mucocele was observed in the four patients who had had a septal flap. In our experience, an approach based on the localization of the IP insertion provided acceptable results in terms of the local control rate (92.6%). However, the significant rate of postoperative mucoceles indicated that specific strategies (such as local flaps) still need to be developed to avoid this iatrogenic complication.

    Full Text Available A variety of non-neoplastic and neoplastic conditions involve the nasal cavity and paranasal sinuses which are commonly encountered in clinical practice. The nose and paranasal sinuses are exposed to a variety of infections, chemically irritating, antigenically stimulating, traumatic and undoubtedly many other influences and consequences of these multifaceted deleterious exposures result in the formation of tumour-like and truly neoplastic conditions. To study histopathological pattern of sinonasal lesions and association of Human Papilloma Virus (HPV with sinonasal papillomas and squamous cell carcinomas. The present study was a hospital based observational study conducted over a period of three years from January, 2010 to January, 2013 in the Department of Pathology, Government Medical College, Srinagar which included 181 cases of non-neoplastic and neoplastic lesions of nasal cavity and paranasal sinuses followed by study of association of HPV with sinonasal papillomas and squamous cell carcinomas by polymerase chain reaction (PCR. Out of total 181 cases, 114 were non-neoplastic and 67 were neoplastic. Out of 67 neoplastic lesions, 46 were benign and 21 were malignant. Nasal polyp was most common among non neoplastic lesions. Inverted sinonasal papilloma was most common benign lesion and squamous cell carcinoma was most common malignant lesion seen. Out of a total of 181 sinonasal lesions 101 (55.8% were present in males and 80 (44.2% were present in females with male to female ratio being 1.26:1. The age range of patients with sinonasal lesions varied from 5-75 years with a mean age being 34.67 (SD±16.58 years. HPV positivity was seen in 4 (13.33% out of 30 cases of inverted papillomas, 3 out of 6 (50% exophytic papillomas tested positive for HPV. Out of 9 squamous cell carcinomas HPV positivity was seen in 2 (22.2% cases. Categorizing the sinonasal lesions according to histopathological features into various types helps us to know the

    The analysis of results of screening (n = 3208; sexually active citizen aged from 18 to 59 years) was carried out to detect oncogene types of human papilloma virus in using qualitative (1150 females and 720 males) and quantitative (polymerase chain reaction in real-time (843 females and 115 males) techniques. The human papilloma virus of high oncogene type was detected in 65% and 68.4% of females and in 48.6% and 53% of males correspondingly. Among 12 types of human papilloma virus the most frequently diagnosed was human papilloma virus 16 independently of gender of examined and technique of analysis. In females, under application of qualitative tests rate of human papilloma virus 16 made up to 18.3% (n = 280) and under application of quantitative tests Rte of human papilloma virus made up to 14.9% (n = 126; p ≤ 0.05). Under examination of males using qualitative tests rate of human papilloma virus 16 made up to 8.3% (n = 60) and under application of qualitative tests made up to 12.2% (n = 14; p ≥ 0.05). Under application of qualitative tests rate of detection on the rest ofoncogene types of human papilloma virus varied in females from 3.4% to 8.4% and in males from 1.8% to 5.9%. Under application of qualitative tests to females rate of human papilloma virus with high viral load made up to 68.4%, with medium viral load - 2.85% (n = 24) and with low viral load -0.24% (n = 2). Under application of quantitative tests in males rate of detection of types of human papilloma virus made up to 53% and at that in all high viral load was established. In females, the most of oncogene types of human papilloma virus (except for 31, 39, 59) are detected significantly more often than in males.

  14. Human Papilloma Viruses and Breast Cancer – Assessment of Causality

    Lawson, James Sutherland; Glenn, Wendy K.; Whitaker, Noel James

    2016-01-01

    High risk human papilloma viruses (HPVs) may have a causal role in some breast cancers. Case–control studies, conducted in many different countries, consistently indicate that HPVs are more frequently present in breast cancers as compared to benign breast and normal breast controls (odds ratio 4.02). The assessment of causality of HPVs in breast cancer is difficult because (i) the HPV viral load is extremely low, (ii) HPV infections are common but HPV associated breast cancers are uncommon, and (iii) HPV infections may precede the development of breast and other cancers by years or even decades. Further, HPV oncogenesis can be indirect. Despite these difficulties, the emergence of new evidence has made the assessment of HPV causality, in breast cancer, a practical proposition. With one exception, the evidence meets all the conventional criteria for a causal role of HPVs in breast cancer. The exception is “specificity.” HPVs are ubiquitous, which is the exact opposite of specificity. An additional reservation is that the prevalence of breast cancer is not increased in immunocompromised patients as is the case with respect to HPV-associated cervical cancer. This indicates that HPVs may have an indirect causal influence in breast cancer. Based on the overall evidence, high-risk HPVs may have a causal role in some breast cancers. PMID:27747193

    Full Text Available The purpose of this study was to establish if the infection with human papilloma virus (HPV presents a potential irreversible evolution towards malignancy. Materials and methods. The study was made on a number of 1885 patients that were suspected to have cervical neoplasia, which were monitored between 2001-2010 in „Elena-Doamna” Clinical Hospital of Obstetrics and Gynecology in Ia�i, the Military Hospital Gala�i, the County Hospital Gala�i and the Emergency Hospital Buzau. Results and discussions. The study proved that the risk of contacting a genital infection with HPV and cervical cancer is influenced by the sexual activity, the risk of getting infected with HPV during a person’ s lifetime is at least 50% for those sexually active. Conclusions. The patients benefited from colposcopy and biopsy only if the repeated cytology suggested more severe changes. The conservative conduct is represented by a repeated cytology when the patients are admitted into the lot (the initial cytology is performed before this moment

    2008-01-01

    AIM: To investigate the presence of human papillomavirus (HPV) in esophageal squamous papilloma (ESP) and determine p16, p53 and Ki67 expression in a Mexican cohort.METHODS: Nineteen cases diagnosed as ESP, corresponding to 18 patients were reviewed; nineteen cases of normal esophageal mucosa were used as negative controls. HPV detection was performed by ,amplified chromogenic in situ hybridization (ACISH) using a wide spectrum-cocktail probe and PCR. RESULTS: The average age at presentation was 46.3 years (range 28-72 years). Patients included four (22.22%) males and 14 (77.77%) females. The most frequent location was upper third (11 cases), followed by middle third (3 cases) and unknown site (5 cases). Immunohistochemistry (IHC) revealed basal and focal p53 expression in 17 cases (89%); p16 was expressed in eight cases (42.10%) and the Ki67 index ranged from 10% to 30%. HPV was detected in 14 out of 16 cases (87.5%) by ACISH: Twelve showed diffuse nuclear patterns and two showed granular patterns. HPV DNA was identified by PCR in 12 out of 14 cases (85.7%). Low-risk HPV types were detected in the most of the cases. CONCLUSION: This study provides identification of HPV infection in almost 80% of ESP using either ACISH or PCR; overall, all of these lesions show low expression of cell-cycle markers. We suggest ACISH as an alternative diagnostic tool for HPV detection in ESP.

    Worldwide, approximately 5 to 10% of the population is infected by a Human Papilloma Virus (HPV). Some of these viruses, with a high oncogenic risk (HPV HR), are responsible for about 5% of cancer. It is now accepted that almost all carcinomas of the cervix and the vulva are due to an HPV HR (HPV16 and 18) infection. However, these viruses are known to be involved in the carcinogenesis of many other cancers (head and neck [SCCHN], penis, anus). For head and neck cancer, HPV infection is considered as a good prognostic factor. The role of HPV HR in anal cancer is also extensively studied in high-risk patient's population. The role of HPV infection in the carcinogenesis of esophageal, bladder, lung, breast or skin cancers is still debated. Given the multiple possible locations of HPV HR infection, the question of optimizing the management of patients with a HPV+ cancer arises in the implementation of a comprehensive clinical and biological monitoring. It is the same in therapeutics with the existence of a preventive vaccination, for example.

    Full Text Available Cervical cancer is the second most common cancer among women and third leading cause of cancer death. Approximately 500,000 women worldwide develop new cases of cervical cancer annually, with 80% of these new cases occurring in developing countries. Human papilloma virus (HPV infection is the main factor associated with the development of cervical cancer. The currently available HPV vaccines, gardasil and cervarix, can prevent infection by certain HPV types, but not all. At present, research efforts are being devoted to developing broader spectrum preventative vaccines, as well as therapeutic vaccines. To confer additional therapeutic activities, chimeric vaccines have been developed. Multivalent vaccine technologies employ strategies for addressing a broader spectrum of HPV types or for combining HPV with other pathogens. Edible vaccines are also disclosed. For needleless immunization, jet gun, gene gun and microneedles have been developed. Biodegradable and mucoadhesive polymer-based vaccine formulations have been developed to deliver vaccines through the mucosa and enhance immunogenicity. Various viral vectors of recombinant HPV DNA vaccine are disclosed. [Int J Basic Clin Pharmacol 2014; 3(1.000: 37-43

    To examine conjunctival papilloma and normal conjunctival tissue for the presence of human papillomavirus (HPV). Archival paraffin wax-embedded tissue from 165 conjunctival papillomas and from 20 histological normal conjunctival biopsy specimens was analysed for the presence of HPV by PCR. Specimens considered HPV positive using consensus primers, but with a negative or uncertain PCR result using type-specific HPV probes, were analysed with DNA sequencing. HPV was present in 86 of 106 (81%) beta-globin-positive papillomas. HPV type 6 was positive in 80 cases, HPV type 11 was identified in 5 cases and HPV type 45 was present in a single papilloma. All the 20 normal conjunctival biopsy specimens were beta-globin positive and HPV negative. There is a strong association between HPV and conjunctival papilloma. The study presents the largest material of conjunctival papilloma investigated for HPV and the first investigation of HPV in normal conjunctival tissue. HPV types 6 and 11 are the most common HPV types in conjunctival papilloma. This also is the first report of HPV type 45 in conjunctival papilloma.

    Oral papilloma is a benign tumourous lesion. Part of this lesion is associated with human papillomavirus (HPV) infection. We analysed the genetical and histopathological evidence for HPV type 2 infection in three oral papillomas. Southern blot hybridization showed HPV 2a sequence in one lesion. Cells of the positive specimen appeared to contain high copy numbers of the viral DNA in an episomal state. In situ staining demonstrated virus capsid antigen in koilocytotic cells and surrounding cells in the hyperplastic epithelial layer. Two other specimens contained no HPV sequences by labeled probe of full length linear HPVs 2a, 6b, 11, 16, 18, 31 and 33 DNA under low stringency hybridization conditions. These results showed the possibility that HPV 2 plays a role in oral papilloma. PMID:9699941

    Full Text Available Background: Controversy surrounds regarding the role of human papillomavirus (HPV in oral precancerous and cancerous lesions in India where smokeless, tobacco consumption is rampant. Aims: The present study was carried out with an aim to investigate the presence and type of HPV infection in oropharyngeal leukoplakia and to determine the association of HPV positivity with various patient and lesion characteristics. Settings and Design: Prospective case series. Materials and Methods: A total of fifty confirmed cases of oral leukoplakia (OL, aged 18–55 years were enrolled in the study. Specimens were obtained from the site of lesion. All the specimens were subjected to histopathological analysis and HPV-16, 18 detection was done using real-time polymerase chain reaction technique. Results: Mean age of patients was 34.00 ± 8.85. Majority were males (62%, from middle social class (78% and were educated up to graduation or above (54%. All the patients had one or more adverse habits (betel, chewing tobacco, smoking and alcohol with mean duration of disease was 3.53 ± 3.05 years. Five patients (10% had diabetes. Burning sensation (86% and trismus (36% were the reported complaints. Maximum were Stage II (50%, sized 2–4 cm2 (60%, homogenous (70%. Floor of mouth and tongue were most commonly involved sites (50%. Majority had mild dysplasia (58%. Acanthosis (66%, hyperplasia (62%, koliocytosis (40%, and keratosis (98% were quite common. HPV (16/18 could not be detected in any specimen. Conclusions: The present study highlighted the fact that association of HPV with oral leukoplakia seems to be overestimated and needs to be reexamined with consensus Human papilloma virus (HPV primers to detect HPV types with more valid empirical relationships.

    Full Text Available Aim: To study an association between acrochordon and human papilloma virus (HPV using quantitative analysis of viral desoxyribonucleic acid (DNA; to detect different phenotypes of beta-HPV. Materials and methods: We examined 52  patients (22 immuno-suppressed patients and 30 immunocompetent subjects in the Dermatovenereology and Dermato-Oncology Department and Chronic Dialysis and Kidney Transplantation Department of the Moscow Regional Research and Clinical Institute (MONIKI. Control group included 49 healthy donors. Burr biopsy samples (micro-samples of acrochordon and intact skin (apper arm were collected in sterile conditions. After sample procession and DNA isolation using DNK-sorb-C kit (Central Research Institute for Epidemiology – CRIE, polymerase chain reaction for HPV was performed with real-time fluorescent hybridization detection. For DNA amplification and detection we used RotorGene 3000 analyzer (Corbett Research, Australia. In the beta-HPV assay, recombinant plasmids were used as positive controls and control human beta-globin gene fragments (CRIE. 4 oligo-nucleotide systems (group-specific primers and probes were used for the detection of beta-HPV DNA. Results: Preliminary data indicated that acrochordons of open and covered skin regions were common in renal transplant recipients. Beta-HPV DNA was more frequent in acrochordons and intact skin (64% and 54% of renal transplant recipients compared to healthy donors (47%. 57% of renal transplant recipients demonstrated mixed infection in acrochordons. Conclusion: HPV DNA was frequently detected in acrochordons and intact skin of renal transplant recipients. In immunocompetent patients prevalence of HPV DNA in acrochordons was significantly higher compared to intact skin.

    Currently, the human papilloma virus (HPV), in addition to tobacco and alcohol, is considered another independent risk factor for oropharyngeal squamous head and neck cancer (OPSCC), where the prevalence of HPV-16 increases to 50-90 % for the oropharynx. Also, incidence and mortality in head and neck SCC (HNSCC) continue to be higher in African Americans (AA) than in Caucasian Americans (CA). A recent study found that poorer survival outcomes for AA versus CA with oropharyngeal tumors were attributable to racial differences in the prevalence of HPV positive (+) tumors; HPV negative (-) AA and CA patients had similar outcomes (Settle et al., Cancer Prev Res (Phila) 2:776-781, 2009). Evidence indicates that a HPV+ diagnosis has significant prognostic implications; these patients have at least half the risk of death when compared with the HPV- patient, due in part to a better response to chemoradiotherapy (Fakhry et al., J Natl Cancer Inst 100:261-269, 2008).Epigenetic events of promoter hypermethylation are emerging as promising molecular strategies for cancer detection, representing tumor-specific markers occurring early in tumor progression. HPV infection is now recognized to play a role in the pathogenesis of OPSCC, where HPV+ and HPV- patients appear to be clinically and biologically distinct with reported genome-wide hypomethylation and promoter hypermethylation in HPV+ HNSCC tumors. A recent study from our group applying pathway analysis to investigate the biological role of the differentially methylated genes in HPV+ and HPV- HNSCC reported 8 signal transduction pathways germane to HNSCC (Worsham et al., Otolaryngol Head Neck Surg 149:409-416, 2013).

    A 51-year-old female presented with a rare case of choroid plexus papilloma originating in the sella turcica manifesting as headaches that was not readily distinguishable preoperatively from pituitary adenoma. Head magnetic resonance imaging revealed a tumor extending from the sella turcica to the suprasellar cistern. The tumor was removed via an endonasal transsphenoidal approach. Histological examination indicated a papillary structure covered with a layer of columnar epithelial cells that resembled normal choroid plexus. These findings, together with immunohistochemistry, led to a diagnosis of choroid plexus papilloma.

    Full Text Available Squamous papillomas are common lesions of the oral mucosa with predilection for mucosa of hard and soft palate. As an oral lesion, it raises concern because of its clinical appearance, which may mimic an epithelial malignancy such as verrucous carcinoma or condyloma acuminatum. Pathogenesis of this lesion though largely unknown can be attributed to human papillomavirus infection, however, slight controversy regarding its viral origin exists. In this compilation, two cases of oral squamous papilloma are presented along with a review of literature.

    The causal lesions by VPH in the cervix, are associated to cancer. Currently 56 different subtypes have been isolated, from which, the 16, 18, 31, 33, 35 and 39 are more frequently related with the cervical intraepithelial neoplasia; from here derives the importance of opportune treatment. The objective of this paper is to evaluate VPH of the cervix opportune treatment with cryosurgery. Seventy five patients were analyzed, from April 1988 to May 1990 with diagnosis of cervical VPH, by cytology, colposcopy and histopathology; in whom cryosurgery with double freezing technique, was practiced; and were evaluated ever six months, during two years with cytology and colposcopy. Whenever there was persistence or recurrence, cryosurgery was used again; doing this even three times, previously discarding intraepithelial cancer. Seventy seven per cent of the patients received only one session; 16% two, and 7% three. At the six months review, it was found that 92% of the cases were negative, and 8% with persistence; at 12 months, 89% negative and 11% with recurrences; at 18 months, 93% negative, 3% with persistence and 4% with recurrence; at 24 months, 96% negative and 4% with recurrence. It is concluded that cryosurgery is efficacious in the treatment of these lesions, easy to use, well tolerated, with minimal side effects, it does not require anesthesia and is of a low cost.

    An unusual case of a sacral, extradural choroid plexus papilloma involving the S1-3 level is described. This 50-year-old woman presented with a 4-month history of pain involving her right buttock, perineum, and leg. Contrast-enhanced magnetic resonance (MR) imaging of the spine revealed a well-defined, mildly enhancing sacral canal mass at the S1-3 level; its appearance was consistent with that of a benign tumor. Intraoperatively, the lesion was found to be extradural in location and was entwined among nerve roots in the sacral canal. Microscopic examination of the gross totally resected tumor revealed typical features of a choroid plexus papilloma. Despite performing a thorough neuroimaging workup (craniospinal contrast-enhanced MR imaging) for an intracranial or spinal primary mass, none was found. The choroid plexus appeared entirely normal; however, both a cavum septum pellucidum and a cavum vergae were noted. Extraneural choroid plexus papilloma, specifically intrasacral, extradural choroid plexus papilloma has not been previously reported. The present example is thought to have arisen either from ectopic choroid plexus tissue or perhaps by metaplasia from ependymal rests.

    Inverted papilloma is a benign epithelial tumor of the nasal cavity. It is known to coexist with malignancy in 5 to 13% of cases, with squamous cell carcinoma being the most common malignancy. Another associated malignancy, one that is extremely rare, is verrucous carcinoma. To the best of our knowledge, no case of verrucous carcinoma occurring alone or in association with another neoplasm has been described in the nasolacrimal system. We report a case of synchronous verrucous carcinoma and inverted papilloma of the lacrimal sac in a 47-year-old man. The patient presented with epiphora, nasal obstruction, swelling of the left medial canthus, and drainage of a foul-smelling fluid from the left nostril. Computed tomography and magnetic resonance imaging detected the presence of a large mass occupying the left nasal cavity and sinuses with extension into the nasopharynx. In addition, bony invasion of the anteroinferomedial wall of the left orbit was noted with extension of the tumor into the orbit itself, which resulted in lateral displacement of the left medial rectus muscle. The patient underwent endoscopic debulking of the left sinonasal lesion. Of note, the surgery had to be completed in stages because of excessive blood loss. Histopathologic examination of the intranasal component of the tumor identified it as an inverted papilloma. One month after the intranasal resection, a left dacryocystectomy was performed; histopathologic examination revealed that an invasive verrucous squamous cell carcinoma had arisen within the inverted papilloma.

    Human papilloma virus was detected by in situ hybridisation in routinely processed paraffin wax sections using a synthetically produced oligonucleotide probe, end-labelled with biotin, and amplified with anti-biotin-immunogold silver staining (anti-biotin-IGSS). This system proved more sensitive than amplification with streptavidin-biotinylated alkaline phosphatase for detecting human papilloma virus type 16 in cervical tissues. The method was successfully combined with antigen staining for papilloma virus common antigens in skin and genital warts. This simple and quick method, using non-radioactively labelled synthetic probes, may be useful for the detection of other viruses in stored material and may be suitable for other double staining procedures.

    2001-01-01

    There are few reports on focal epithelial hyperplasia (FEH) in association with human immunodeficiency virus (HIV) infection; thus the relationship between them has not been completely clarified yet. We present a case of recurrent FEH in an HIV-positive man (the first described in Belgium), which, according to the PCR-DNA testing, was due to human papilloma virus type 13 (HPV13). To our knowledge, based on the accessible literature, this type of HPV has not been detected in any other documented study of FEH in HIV-positive patients before. Our patient experienced three recurrences of FEH in 1 year. It is therefore suggested that immunodeficiency due to HIV infection is responsible for the HPV-related FEH and the subsequent recurrences. In order to support the consideration of FEH as an oral manifestation of an HIV-related opportunistic infection, every new 'HPV-type' oral lesion in HIV-positive patients must be completely documented.

    The follow-up schedule of women who have undergone treatment for high grade squamous intraepithelial lesions (HSIL) is a crucial part of the cervical screening programme. The ability to detect residual disease or early recurrence enables the provision of timely secondary intervention. The aim of this study was to determine the prevalence of High Risk HPV and cytological abnormalities at first follow-up visit post treatment. The feasibility, safety and cost benefit of omitting routine colposcopy as a first line investigation were evaluated. A total of 100 women with histologically confirmed and treated HSIL were recruited prior to first follow-up visit. Colposcopic assessment, cervical cytology using LBC and HR HPV testing was carried out on all women. In all, 75% of the study group had both a negative HR HPV test and a normal cervical cytology at first follow-up visit. Mean time interval to first follow-up was 9 months. The rate of residual/recurrent high-grade disease within this cohort was 4% followed up to 18 months post treatment. HR HPV had a sensitivity of 100% to detect persistent HSIL. High-risk human papilloma virus testing in combination with cytology at first follow-up visit in women treated for HSIL has a very high sensitivity and negative predictive value. Colposcopy does not improve specificity in this cohort and could be omitted in patients who have a negative smear and HPV test.

    2005-01-01

    Cutaneous papillomatous lesions were biopsied from three captive Florida manatees (Trichechus manatus latirostris) at Homosassa Springs State Wildlife Park (HSSWP), Homosassa, Florida, USA, and from six free-ranging Florida manatees from Crystal and Homosassa rivers, Florida. Total DNA extracted from these lesions was assayed for the presence of papilloma virus genomes using the polymerase chain reaction (PCR) with primers that target the L1 capsid protein gene. The amplification generated DNA fragments 458 base pairs in length that encompassed a highly conserved domain within the L1 capsid protein and translated into identical polypeptides of 152 amino acids, suggesting the involvement of a single papilloma virus genotype. Multiple amino acid sequence and phylogenetic analyses of the L1 fragment indicated that the Florida manatee papilloma virus is a unique and quite distinct papillomavirus from other known papilloma viruses. The emergence of this new pathogen raises concerns about its potential impact on the already endangered Florida manatee.

    This study investigated long-term survival outcomes in surgically treated oropharyngeal cancer patients with known human papilloma virus status. A case note review was performed of all patients undergoing primary surgery for oropharyngeal cancer in a single centre over a 10-year period. Human papilloma virus status was determined via dual modality testing. Associations between clinicopathological variables and survival were identified using a log-rank test. Of the 107 cases in the study, 40 per cent (n = 41) were human papilloma virus positive. The positive and negative predictive values of p16 immunohistochemistry for human papilloma virus status were 57 per cent and 100 per cent, respectively. At a mean follow up of 59.5 months, 5-year overall and disease-specific survival estimates were 78 per cent and 69 per cent, respectively. Human papilloma virus status (p = 0.014), smoking status (p = 0.021) and tumour stage (p = 0.03) were significant prognostic indicators. The long-term survival rates in surgically treated oropharyngeal cancer patients were comparable to other studies. Variables including human papilloma virus status and tumour stage were associated with survival in patients treated with primary surgery; however, nodal stage and presence of extracapsular spread were non-prognostic.

    Squamous cell carcinoma (SCC) and squamous papilloma are rarely reported as primary lesions of the cornea in dogs. One case of corneal papilloma and 3 cases of SCC, each arising as a primary central corneal neoplasm rather than spreading from adjacent limbal conjunctiva, were reviewed. The most common cause of SCC in animals is chronic exposure of lightly pigmented epithelium to UV light; however, all dogs in this study had a history of chronic pigmentary keratitis. Three of the 4 dogs were of brachycephalic breeds with naturally proptotic eyes and oversized palpebral fissures that may have exposed the cornea to greater excessive solar radiation. Alternatively, mechanical factors that caused chronic changes in the cornea may have been causative factors for induction of primary dysplastic or neoplastic changes. Primary corneal neoplasia should be considered in the differential diagnosis of corneal masses.

    Esophageal cancer is a prevalent cancer worldwide. Some studies have reported the possible etiology of human papillomavirus (HPV) in benign and malignant papillomas of the esophagus but the conclusions are controversial. In the present study, we investigated an esophageal papilloma from a 30-year-old male patient presenting aphasia. HPV DNA was detected by generic PCR using MY09/11 primers, and restriction fragment length polymorphism revealed the presence of HPV54, usually associated with benign genital lesions. Hypermethylation of the pINK4A gene was also investigated due to its relation to malignant transformation, but no modification was detected in the host gene. Except for an incipient reflux, no risk factors such as cigarette smoking, alcohol abuse or an infected sexual partner were recorded. Since esophageal lesions may have a malignant potential, HPV detection and typing are useful tools for patient follow-up.

    Mixed squamous cell and glandular papilloma of the lung is an extremely rare benign neoplasm. Here we present another case of mixed squamous cell and glandular papilloma in a 64-year-old female nonsmoker. Histologically, the tumor was composed of mainly papillary structures covered with squamous, glandular and transitional epithelium. Some glandular structures extending into adjacent bronchiolar and alveolar spaces with mucus were similar to adenocarcinoma. Immunohistochemical analysis showed the different kinds of epithelia had similar immunophenotype. The different components were positive for cytokeratin (CK)7, CK19, CAM5.2, CK5/6, CK34βE12, and TTF-1, but negative for CK20. The transitional morphology and immunohistochemistry indicate the different components likely come from a same kind of progenitor in the bronchiolar wall.

    Full Text Available Background: The extent of association of human papilloma virus (HPV in human conjunctival neoplasias has been debated in studies originating from different parts of the world, but no substantial evidence has been generated on Indian subjects. This prompted us to carry out a retrospective study on conjunctival neoplasias diagnosed over the past 12 years. Materials and Methods: Histopathological and immunohistochemical analysis of 65 specimens of ocular neoplasias and 30 normal controls diagnosed between 1991 and 2002 at a tertiary eye care hospital, was undertaken. Formalin-fixed, paraffin-embedded tissues were reviewed for confirming histopathological diagnosis, presence of koilocytosis and changes related to actinic keratosis. Immunohistochemical analysis was done using HPV-specific monoclonal antibodies. Clinicopathological correlation and the association of HPV antigen with the histopathological features were performed. Results: Out of the 65 cases analyzed, 35 were papillomas and 30 were ocular surface squamous neoplasias (OSSN. The mean age was 48 years with a male preponderance. Histologically, koilocytosis was observed in 17.1% of papillomas and 36.6% of OSSN. Actinic keratosis was present in 33% of OSSN. Immunohistochemically 17.1% conjunctival papillomas stained positive for HPV antigen, all cases of OSSN were negative for HPV. There was no correlation between koilocytosis or actinic keratosis and the detection of HPV antigen. Conclusions: The association between HPV and conjunctival neoplasias is variable in different geographical areas and also depends on the methods of detection used. This study warrants the need for applying more advanced techniques at a molecular level to determine the possible etiology of HPV in conjunctival neoplasias among Asian-Indians.

    Human papilloma virus causes genital cancers. Decreases in cervical cancer have been reported to be due to comprehensive screening programmes difficult to replicate in poorer countries. HPV cancer may be related to poverty. In Jamaica, we have seen decreases in cancer of the penis and vulva and there has also been a decrease in poverty. The decrease cannot be attributed to screening. We believe elimination of poverty has decreased HPV persistence and decreased cancer rates.

    Background: The extent of association of human papilloma virus (HPV) in human conjunctival neoplasias has been debated in studies originating from different parts of the world, but no substantial evidence has been generated on Indian subjects. This prompted us to carry out a retrospective study on conjunctival neoplasias diagnosed over the past 12 years.

    Background: Oral lichen planus (OLP) is a common chronic inflammatory mucocutaneous disease. Clinical diagnosis of OLP requires clinical work-up and histologic examination to rule out possible dysplasia and carcinoma. It is possible that oral mucosal viral infections including HPV infection may have a causative role in OLP pathogenesis. The aim of this study was to examine the co-incidence of human papilloma virus type 18 and oral lichen planus. Methods: This study was a case-control stud...

    sophageal squamous papilloma is an uncommon, usually asymptomatic, benign tumor of the squamous epithelium consisting of a raised, sessile, small and round (smooth or rough) lesion. The prevalence is between 0.01 and 0.45% of cases, with a male/female ratio of 3:1. The etiology and pathogenesis appear to be a mechanical or chemical irritation of the mucosa in addition to the presence of human papillomavirus (HPV), important agent in the evolution to a squamous carcinoma, especially HPV types 16 and 18. In this paper, we describe a case of esophageal papilloma whose diagnosis involved endoscopic images, pathological studies and detection of viral DNA by polymerase chain reaction. By using molecular techniques (PCR-RFLP) a profile consistent with HPV type 16 has been obtained. The patient underwent polypectomy and currently, after 3 years of diagnosis, he remains asymptomatic. This work is one of the first national reports of a patient with esophageal papilloma in which one of the most frequently HPV genotypes associated with esophageal carcinoma (HPV 16) has been detected.

    Inverted Papilloma is a unique neoplasm characterized by its tendency to destroy bone, tendency to recur after incomplete removal and association with malignancy. The uncertainty of its clinical features and projected behaviour has resulted in an ill-defined approach to its management. This is a prospective study of 30 patients of Inverted Papilloma admitted at Regional Institute of Medical Sciences, Imphal between August 2001 to July 2003. In this study, meticulous attention is given to the clinical presentation and management in a series of 30 patients with inverted papilloma. A majority of patients were between 50-70 years (40%) with a mean age of 52.3 years. M: F Ratio=3.3:1. Commonest presenting symptoms were unilateral nasal obstruction (93.3%), nasal discharge (40%) and epistaxis (36.6%). 90% of the patients had signs of involvement of the nasal cavity with one or more sinuses and 46% showed bony erosion on C.T. Scan studies. Surgery was the treatment of choice in 90% of the cases.

    Recurrence plots display binary texture of time series from dynamical systems with single dots and line structures. Using fuzzy recurrence plots, recurrences of the phase-space states can be visualized as grayscale texture, which is more informative for pattern analysis. The proposed method replaces the crucial similarity threshold required by symmetrical recurrence plots with the number of cluster centers, where the estimate of the latter parameter is less critical than the estimate of the former.

    Recurrent respiratory papillomatosis is a viral-induced disease, associated with exophytic epithelial lesions affecting the upper airways. Problem of treatment is the high recurrence of papilloma growth after surgical removal; therefore, adjuvant therapy schemes have been established. We used cidofovir, 7.5 mg/ml, in adjuvant therapy in the past years. Out of 31 adult patients treated with the drug, 26 (83.9 %) are at the moment in complete response. 19 (73 % of pts with CR) of those 26 patients were cured with a number of injections between 1 and 4 (mean 2.5). We did not see any clinical manifestation of renal toxicity or neutropenia (superinfection) necessitating a blood test. Six patients presented dysplasia during the treatment with the drug, while six patients had dysplasia prior to cidofovir injection. Due to recurrent nature of the disease and the high number of mechanical and laser surgeries required we treated one tracheal stenosis, two scarred larynx, and two glottic synechiaes. There is still an ongoing discussion within the European Laryngological Society about the effectiveness and possible side effects of this drug. Results show promising long-term effects of adjuvant use of cidofovir, without any relevant side effects.

    Human Papilloma Virus has a strong relation to oropharyngeal mucosa and is considered to be responsible for a wide range of upper respiratory tract pathologies, like laryngeal papilloma. There's a hypothesis, that it plays a significant role in middle ear chronic inflammations and neoplasm's. MATERIAL AND METHODIC. The examination was carried on a group of 53 patients, 39 of which was suffering from granulation tissue chronic otitis media, 7-cholesteatomatous otitis media, 6--middle ear malignant neoplasm, and 1 middle and/or external ear benign neoplasm. The control group consisted of 5 patients operated on: otosclerosis--4 cases and post-traumatic tympanic membrane perforation--1 case. The material was postoperative tissue, like polyps, inflammatory granulation tissue, cholesteatoma masses and malignant neoplasm's tissue. In the whole group of 53 examined cases, HPV DNA was confirmed in 22 cases (41.5%), in that group oncogenic types 16 or 18 in 12 cases (22.6%), and in 14 cases (26.4%) types 6 or 11. In a group of chronic granulomatous otitis media DNA characteristic for Papilloma was identified in 12 cases (25.6%), in it in 9 cases DNA HPV type 6 or 11 was confirmed, and in 7 cases type 16 or 18. Among cholesteatomatous chronic otitis media HPV DNA types 6 or 11 was identified in 70%. In every case of middle ear malignant neoplasm a presence of high-risk DNA Papilloma types 16 or 18 was confirmed. In any case of control group HPV DNA was detected. The results has been compared with other authors examinations and it is claimed that they confirm the observation, that Human Papilloma Viruses may be a factor, that might play an important role in pathology of chronic otitis media and ear neoplasm's. It is concluded, that differences in percentages of HPV presence in chronic inflammations (70%) and ear neoplasm's may be explained by viral co-infection during bacterial c. o. m. Viral infection probably evolves carcinogenesis, which leads to a neoplastic growth.

    Full Text Available Benign oropharyngeal tumors are far less common compared to malignant tumors. Oropharyngeal papilloma is present in adults. Squamous papillomas are exophytic masses of oral cavity. When they occur on the palate they are most often asymptomatic and benign. Pedunculated squamous papillomas usually arise from the soft palate, tonsil, or the epiglottis. These lesions can sometimes prove to be fatal. A case of pedunculated squamous papilloma, arising from the laryngopharynx, the clinical presentation, the site of origin, and the size of the lesion were quite unusual. The narrow base of the pedicle made the intraoral excision possible. But here, we present a case of a 10-year-old boy who had history of dysphagia of 3-year duration for solid food and he was comfortable only in squatting position the reason being squamous papilloma of uvula (unusual site atypically because of astonishing length of pedicle (2.3 inches.

    We report 2 cases of a lesion that we term inverted papilloma of the lower female genital tract, occurring in the cervix and upper vagina of 60- and 50-year-old women, respectively. Microscopically, the features were similar to those of inverted transitional papilloma of the urinary bladder with interconnecting islands, trabeculae, and solid sheets of bland transitional epithelium with an inverted growth pattern. There were small foci of squamous and glandular differentiation in the cervical case. Linear array human papillomavirus genotyping revealed human papillomavirus type 42 in both cases. Inverted papilloma in the lower female genital tract is extremely rare with, as far as we are aware, only 3 previously reported similar cases in the cervix and none in the vagina. Our results suggest that these neoplasms when occurring in the lower female genital tract may be associated with low-risk human papillomavirus, perhaps specifically human papillomavirus 42.

    We present a child with a cerebellar medulloblastoma, diagnosed at age three, treated with near total surgical resection, radiotherapy, and chemotherapy, that recurred 13 years after the initial diagnosis. This late recurrence exceeds the typical 10-year survival statistics that are in common use, and exceeds the Collins rule. Continued follow-up of these children is justified to increase the likelihood of detecting these late recurrences early and to learn more about these late recurrences.

    Objective: In order to study the clinical manifestation and risk factor of recurrent intracerebral hemorrhage(ICH).Methods:The 256 patients were analysed who admitted to our hospital for intracerebral hemorrhage between 1995 and 1997.The 15(5 .86%)patients had a recurrent ICH.There were 9 men and 6 women and the mean age of the patients was 63.5 ± 6.4years at the first bleeding episode and 67.8± 8. 5 years at the second. The mean interval between the two bleeding episodes was 44.6 ± 12.5 months. The 73.3%patients were hypertensive .′The site of the first hemorrhage was ganglionic in 8 patients , ]ohar in six paients and brainstem in one .The recurrent hemorrhage occurred at a different location from the previous ICH.The most common pattern of recurrence was “ganglionic -ganglionic” (7 patients), lobar - ganglionic (3 patients), lobar-lobar(three patients), which was always observed in hypertensive patients. The outcome after the recurrent hemorrhage was usually poor. By comparison with 24 patients followed up to average 47.5± 18.7 months with isolated ICH without recurrence .Only lobar hematoma and a younger age were risk factors for recurrences whereas sex and previous hypertension were not. The mechanism of recurrence of ICH were multiple(hypertension, cerebral amyloid angiopathy).Contral of blood pressure and good living habit after the first hemorrhage may prevent ICH recurrences.

  7. Optimal Recurrence Grammars

    2015-01-01

    We optimally estimate the recurrence structure of a multivariate time series by Markov chains obtained from recurrence grammars. The goodness of fit is assessed with a utility function derived from the stochastic Markov transition matrix. It assumes a local maximum for the distance threshold of the optimal recurrence grammar. We validate our approach by means of the nonlinear Lorenz system and its linearized stochastic surrogates. Finally we apply our optimization procedure to the segmentation of neurophysiological time series obtained from anesthetized animals. We propose the number of optimal recurrence domains as a statistic for classifying an animals' state of consciousness.

    Full Text Available ABSTRACT INTRODUCTION: Chronic rhinosinusitis with nasal polyps is a multifactorial disease entity with an unclear pathogenesis. Contradictory data exist in the literature on the potential implication of viral elements in adult patients with chronic rhinosinusitis. OBJECTIVE: To compare the prevalence of human herpes viruses (1-6 and Human Papilloma Virus in adult patients with chronic rhinosinusitis with nasal polyps and healthy controls. METHODS: Viral DNA presence was evaluated by real-time polymerase chain reaction application to nasal polyps specimens from 91 chronic rhinosinusitis with nasal polyps patients and nasal turbinate mucosa from 38 healthy controls. RESULTS: Epstein-Barr virus positivity was higher in nasal polyps (24/91; 26.4% versus controls (4/38; 10.5%, but the difference did not reach significance (p = 0.06. Human herpes virus-6 positivity was lower in nasal polyps (13/91; 14.29% versus controls (10/38; 26.32%,p = 0.13. In chronic rhinosinusitis with nasal polyps group, 1 sample was herpes simplex virus-1-positive (1/91; 1.1%, and another was cytomegalovirus-positive (1/91; 1.1%, versus none in controls. No sample was positive for herpes simplex virus-2, varicella-zoster virus, high-risk-human papilloma viruses (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and low-risk-human papilloma viruses (6, 11. CONCLUSION: Differences in Epstein-Barr virus and human herpes virus-6 positivity among patients with chronic rhinosinusitis with nasal polyps and healthy controls are not statistically significant, weakening the likelihood of their implication in chronic rhinosinusitis with nasal polyps pathogenesis.

    2016-04-01

    Takotsubo cardiomyopathy, or transient left ventricular apical ballooning syndrome, is characterized by acute left ventricular dysfunction caused by transient wall-motion abnormalities of the left ventricular apex and mid ventricle in the absence of obstructive coronary artery disease. Recurrent episodes are rare but have been reported, and several cases of takotsubo cardiomyopathy have been described in the presence of hyperthyroidism. We report the case of a 55-year-old woman who had recurrent takotsubo cardiomyopathy, documented by repeat coronary angiography and evaluations of left ventricular function, in the presence of recurrent hyperthyroidism related to Graves disease. After both episodes, the patient's left ventricular function returned to normal when her thyroid function normalized. These findings suggest a possible role of thyroid-hormone excess in the pathophysiology of some patients who have takotsubo cardiomyopathy.

    2016-03-01

    Vaccination against the sexually transmitted Human Papilloma Virus (HPV), a necessary agent for the development of cervical cancer, has triggered much debate. In Austria, HPV policy turned from "lagging behind" in 2008 into "Europe's frontrunner" by 2013. Drawing on qualitative research, the article shows how the vaccine was transformed and made "good enough" over the course of five years. By means of tinkering and shifting storylines, policy officials and experts disassociated the vaccine from gender, vaccine manufacturers, and youth sexuality. Ultimately, the HPV vaccine functioned to strengthen the national immunization program. To this end, preventing an effective problematization of the extant screening program was essential.

    Full Text Available Human papilloma virus (HPV, known to be an etiological agent for genital cancers, has been suggested also to be a possible contributory agent for lung cancer. Alternatively, lung cancer, formerly considered to be solely a smoker's disease, may now be more appropriately categorised into never smoker's and smoker's lung cancer. Through this paper we attempt to bring forth the current knowledge regarding mechanisms of HPV gaining access into the lung tissue, various strategies involved in HPV-associated tumorigenesis in lung tissue.

    Laporta, Robert F.; Taichman, Lorne B.

    1982-06-01

    Human papilloma virus (HPV) is poorly understood because systems for its growth in tissue culture have not been developed. We report here that cultured human epidermal keratinocytes could be infected with HPV from plantar warts and that the viral DNA persisted and replicated as a stable episome. There were 50-200 copies of viral DNA per cell and there was no evidence to indicate integration of viral DNA into the cellular genome. There was also no evidence to suggest that viral DNA underwent productive replication. We conclude that cultured human epidermal keratinocytes may be a model for the study of certain aspects of HPV biology.

    For the investigation of laser plume for the existence of HPV DNA fragments, which possibly occur during laser treatment of virus infected tissue, human papillomas and condylomas were treated in vitro with the CO2-laser. For the sampling of the laser plume a new method for the trapping of the material was developed by use of water-soluble gelatine filters. These samples were analyzed with the polymerase chain reaction (PCR) technique, which was optimized in regard of the gelatine filters and the specific primers. Positive PCR results for HPV DNA fragments up to the size of a complete oncogene were obtained and are discussed regarding infectiousity.

    Full Text Available Background: Human Papilloma Virus has been considered as the precursor of flat lesions in the cervical epithelium which develops Cervix uterine cancer. Objectives: to analyze risk factors associated to infections due to human papilloma virus. Method: An ambispective, descriptive study was carried out from January 2003 to January 2004, taking 60 patients whose Papanicolaou smears were abnormal. All these patients belonged to health area V, in Cienfuegos, Cuba. A guide for interview with different variables was used. Results: infected predominant ages were from 30 to 39 years old. 55% of the patients are married women or with stable sexual relationships. 6 patients comprised between 40 to 59 years old were observed with association to intra epithelium cervix neoplasias. For a 10 % of them, they have had from 3 to 12 sexual partners. The starting age to have sexual intercourse is from 15 to 19 years old. 75 % of the patients are smokers. Conclusions: results coincide with the medical literature reviewed regarding risk factors and its important relationship with NIC and so the cervicouterine cancer genesis.

    This study aimed to examine atypical and malignant papillary oral lesions for low- and high-risk human papillomavirus (HPV) infection and to correlate HPV infection with clinical and pathologic features. Sections of 28 atypical papillary lesions (APLs) and 14 malignant papillary lesions (MPLs) were examined for HPV by in situ hybridization and for p16 and MIB-1 by immunohistochemistry; 24 conventional papillomas were studied for comparison. Low-risk HPV was found in 10 of 66 cases, including 9 APLs and 1 papilloma. All low-risk HPV-positive cases showed suprabasilar MIB-1 staining, and the agreement was statistically significant (P < .0001). Diffuse p16 staining combined with high-risk HPV was not seen in any of the cases. A subset of HPV(-) APLs progressed to carcinoma. Oral papillary lesions are a heterogeneous group. Low-risk HPV infection is associated with a subset of APLs with a benign clinical course. Potentially malignant APLs and MPLs are not associated with low- or high-risk HPV.

    Background Fascin, an actin binding protein, usually expressed at a low level in normal epithelium, but is significantly increased in transformed epithelial cells and several common carcinomas. In this study, we examined the expression of fascin by immunohistochemistry in sinonasal epithelium with chronic inflammation (control group), exophytic papilloma(EP), inverted papilloma (IP) with dysplasia and cancerated IP (including carcinoma in situ and invasive squamous cell carcinoma, SCC), and furthermore investigated the relationship between fascin expression and formation of malignant IP.Methods Fascin expression was immunohistochemically detected using monoclonal antibody against fascin in 86paraffin embedded tissues, including 10 cases of sinonasal mucosa with chronic inflammation, 10 of EP, 45 of IP with dysplasia (45 cases were divided into three groups: IP with mild dysplasia, IP with moderate dysplasia, and IP with severe dysplasia, 15 cases each), and 21 of cancerated IP.Results The level of fascin expression was significantly higher in the neoplastic tissue than that in control group. Fascin expression increased gradually with the progression from sinonasal epithelium with chronic inflammation, IP with mild dysplasia, IP with moderate dysplasia, IP with severe dysplasia, to cancerated IP, and significant difference of fascin expression was observed between any two groups of the five.Conclusion Precancerous lesions of IP exhibit elevated levels of fascin that may be associated with carcinogenesis of IP. Fascin may play a role in the formation of IP and EP.

    Full Text Available Introduction: Human Papilloma Virus (HPV is one of the most common causes of sexually transmitted diseases in both men and women worldwide. Aim: The investigation of the knowledge of university students and their mothers about the HPV, the ways of transmission, prevention and vaccination. Material and Method: The studied population consisted of 605 students from Technological Educational Institute of Athens and 50 mothers which filled two different questionnaires with closed-ended questions. Data was statistically processed with Microsoft Excel and SPSS ver.20. Results: Although, a large percentage (84.5% of the questioned students were sexually active, the majority of them (67.7% had never done the human papilloma virus vaccine and they didn’t intended to do it (87.9%. Although questioned mothers were aware that both girls and boys should be vaccinated against HPV infection (83.7%, only 71.4% of them had vaccinated their children, because of their fear of possible side effects (p0.05. Conclusion: Although students and mothers were aware of the HPV and its prevention, they were not familiar with the safety and the effectiveness of the vaccine, maybe because more students had been informed about the HPV from their family mostly than their gynecologist.

    A patient with intraductal papilloma who had abnormal bloody discharge from Montgomery's areolar tubercle underwent mammary ductography, mammary ductoscopy from the tubercle, and microdochectomy.A 43-year-old woman who was being followed-up for left breast cancer noticed bloody discharge from Montgomery's areolar tubercle of the right breast. Because the discharge continued for 2 months, further examinations were conducted. Mammary ductoscopy of Montgomery's areolar tubercle showed a normal internal duct structure. The presence of yellowish superficial lesions suggested intraductal inflammation or superficial hyperplasia of the duct epithelium. Lavage cytology revealed benign papillary lesions. Since the discharge continued and we could not completely exclude malignancy, microdochectomy was performed. Histologically a lactiferous duct was connected to Montgomery's areolar tubercle and an intraductal papilloma was seen in part and considered to have caused the bloody discharge. Bloody discharge from Montgomery's areola tubercles is extremely rare, the present case was our first experience with ductoscopy of Montgomery's areolar tubercle out of 641 cases of mammary ductoscopy performed on patients with bloody nipple discharge from 1998 to 2004. In our case, Montgomery's areolar tubercles were connected to a lactiferous duct. Although there are a few breast carcinomas that cause bloody discharge and eruption of areola, areolar preservation should be performed with the knowledge that disease may also involve the areola through the lactiferous ducts.

    Full Text Available Purpose: The aim of this study was to identify the knowledge and awareness about human papilloma virus (HPV and human papilloma virus (HPV vaccine of women in reproductive age. Material and Methods: The study covered 294 women aged between 15 and 49. A questionnaire was prepared by the researchers based on the literature review. Results: The mean age of the participants was 30.5+/-8.9 years. Only 24.5% had heard about HPV infection and 28.2% had heard HPV vaccine. Of the participants, 188 (63.9% got zero point from the knowledge questions. Conclusion: This study indicates that the women who apply primary care units have low knowledge levels; it is apperent that personal and social education is needed. Paying importance to patient education on HPV and cervical cancer in primary care health politics will increase knowledge and awareness for HPV infection and HPV vaccination.

    To adapt and psychometrically test the Health Belief Model Scale for Human Papilloma Virus (HPV) and Its Vaccination (HBMS-HPVV) for use in a Turkish population and to assess the Human Papilloma Virus Knowledge score (HPV-KS) among female college students. Instrument adaptation and psychometric testing study. The sample consisted of 302 nursing students at a nursing school in Turkey between April and May 2013. Questionnaire-based data were collected from the participants. Information regarding HBMS-HPVV and HPV knowledge and descriptive characteristic of participants was collected using translated HBMS-HPVV and HPV-KS. Test-retest reliability was evaluated and Cronbach α was used to assess internal consistency reliability, and exploratory factor analysis was used to assess construct validity of the HBMS-HPVV. The scale consists of 4 subscales that measure 4 constructs of the Health Belief Model covering the perceived susceptibility and severity of HPV and the benefits and barriers. The final 14-item scale had satisfactory validity and internal consistency. Cronbach α values for the 4 subscales ranged from 0.71 to 0.78. Total HPV-KS ranged from 0 to 8 (scale range, 0-10; 3.80 ± 2.12). The HBMS-HPVV is a valid and reliable instrument for measuring young Turkish women's beliefs and attitudes about HPV and its vaccination.

    The aim of this study was to determine the validity and reliability of the 'Cervical Cancer and Human Papilloma Virus Awareness Questionnaire' among fertility age women by adapting the scale into Turkish. Cervical cancer is the fourth most commonly form seen among women. Death from cervical cancer ranks third among causes and is one of the most preventable forms of cancer. This cross-sectional study included 360 women from three family health centres between January 5 and June 25, 2014. Internal consistency showed that the Kuder-Richardson 21 reliability coefficient in the first part was 0.60, Cronbach's alpha reliability coefficient was 0.61 in the second part. The Kaiser-Meyer-Olkin value of the items on the scale was 0.712. The Barlett test was significant. The confirmatory factor analysis indicated that the model matched the data adequately. This study shows that the Turkish version of the instrument is a valid and reliable tool to evaluate knowledge, perceptions and preventive behaviours of women regarding human papilloma virus and cervical cancer. Nurses who work in the clinical and primary care settings need to screen, detect and refer women who may be at risk from cervical cancer. © 2016 International Council of Nurses.

    Full Text Available Background: Oral lichen planus (OLP is a common chronic inflammatory mucocutaneous disease. Clinical diagnosis of OLP requires clinical work-up and histologic examination to rule out possible dysplasia and carcinoma. It is possible that oral mucosal viral infections including HPV infection may have a causative role in OLP pathogenesis. The aim of this study was to examine the co-incidence of human papilloma virus type 18 and oral lichen planus. Methods: This study was a case-control study. Twenty nine paraffinized specimens of previously diagnosed oral lichen planus and 14 paraffinized specimens of nonpathogenic mucosa were studied. Polymerase Chain Reaction ( PCR analyze used for detection of DNA HPV 18 .The data were ana-lyzed with SPSS software and Fisher′s exact test was used to find the possible relation between HPV18 infection and oral lichen planus. Results: Nine out of 29 (31.0% lichen planus samples and one out of 14 (7.1% controls were HPV 18 positive. No significant correlation (P = 0.128 was observed between HPV18 infection and oral lichen planus. Conclusion: According to the findings there might be a coincidence of human papilloma virus type 18 and oral lichen planus.

    Chemical induction of squamous tumors in the mouse skin induces multiple benign papillomas: high-frequency terminally benign low-risk papillomas and low-frequency high-risk papillomas, the putative precursor lesions to squamous cell carcinoma (SCC). We have compared the gene expression profile of twenty different early low- and high-risk papillomas with normal skin and SCC. Unsupervised clustering of 514 differentially expressed genes (Pclassifier algorithms generated a gene list that correctly classified unknown benign tumors as low- or high-risk concordant with promotion protocol and keratin profiling. Reduced expression of immune function genes characterized the high-risk papillomas and SCC. Immunohistochemistry confirmed reduced T-cell number in high-risk papillomas, suggesting that reduced adaptive immunity defines papillomas that progress to SCC. These results demonstrate that murine premalignant lesions can be segregated into subgroups by gene expression patterns that correlate with risk for malignant conversion, and suggest a paradigm for generating diagnostic biomarkers for human premalignant lesions with unknown individual risk for malignant conversion.

    Recurrent AKI is common among patients after hospitalized AKI and is associated with progressive CKD. In this study, we identified clinical risk factors for recurrent AKI present during index AKI hospitalizations that occurred between 2003 and 2010 using a regional Veterans Administration database in the United States. AKI was defined as a 0.3 mg/dl or 50% increase from a baseline creatinine measure. The primary outcome was hospitalization with recurrent AKI within 12 months of discharge from the index hospitalization. Time to recurrent AKI was examined using Cox regression analysis, and sensitivity analyses were performed using a competing risk approach. Among 11,683 qualifying AKI hospitalizations, 2954 patients (25%) were hospitalized with recurrent AKI within 12 months of discharge. Median time to recurrent AKI within 12 months was 64 (interquartile range 19-167) days. In addition to known demographic and comorbid risk factors for AKI, patients with longer AKI duration and those whose discharge diagnosis at index AKI hospitalization included congestive heart failure (primary diagnosis), decompensated advanced liver disease, cancer with or without chemotherapy, acute coronary syndrome, or volume depletion, were at highest risk for being hospitalized with recurrent AKI. Risk factors identified were similar when a competing risk model for death was applied. In conclusion, several inpatient conditions associated with AKI may increase the risk for recurrent AKI. These findings should facilitate risk stratification, guide appropriate patient referral after AKI, and help generate potential risk reduction strategies. Efforts to identify modifiable factors to prevent recurrent AKI in these patients are warranted. Copyright © 2016 by the American Society of Nephrology.

    Cervical cancer is strongly related to certain high-risk types of human papilloma virus infection. Breast cancer metastasis suppressor 1 (BRMS1) is a tumor suppressor gene, its expression being regulated by DNA promoter methylation in several types of cancers. This study aims to evaluate the methylation status of BRMS1 promoter in relation to high-risk types of human papilloma virus infection and the development of pre-cancerous lesions and describe the pattern of BRMS1 protein expression in normal, high-risk types of human papilloma virus-infected pre-cancerous and malignant cervical epithelium. We compared the methylation status of BRMS1 in cervical smears of 64 women with no infection by high-risk types of human papilloma virus to 70 women with proven high-risk types of human papilloma virus infection, using real-time methylation-specific polymerase chain reaction. The expression of BRMS1 protein was described by immunohistochemistry in biopsies from cervical cancer, pre-cancerous lesions, and normal cervices. Methylation of BRMS1 promoter was detected in 37.5% of women with no high-risk types of human papilloma virus infection and was less frequent in smears with high-risk types of human papilloma virus (11.4%) and in women with pathological histology (cervical intraepithelial neoplasia) (11.9%). Methylation was detected also in HeLa cervical cancer cells. Immunohistochemistry revealed nuclear BRMS1 protein staining in normal high-risk types of human papilloma virus-free cervix, in cervical intraepithelial neoplasias, and in malignant tissues, where staining was occasionally also cytoplasmic. In cancer, expression was stronger in the more differentiated cancer blasts. In conclusion, BRMS1 promoter methylation and aberrant protein expression seem to be related to high-risk types of human papilloma virus-induced carcinogenesis in uterine cervix and is worthy of further investigation.

    The transitions from or to strange nonchaotic attractors are investigated by recurrence plot-based methods. The techniques used here take into account the recurrence times and the fact that trajectories on strange nonchaotic attractors (SNAs) synchronize. The performance of these techniques is shown for the Heagy-Hammel transition to SNAs and for the fractalization transition to SNAs for which other usual nonlinear analysis tools are not successful.

    Full Text Available Nanosecond pulsed electric fields (nsPEF induce apoptotic pathways in human cancer cells. The potential therapeutic effective of nsPEF has been reported in cell lines and in xenograft animal tumor model. The present study investigated the ability of nsPEF to cause cancer cell death in vivo using carcinogen-induced animal tumor model, and the pulse duration of nsPEF was only 7 and 14 nano second (ns. An nsPEF generator as a prototype medical device was used in our studies, which is capable of delivering 7-30 nanosecond pulses at various programmable amplitudes and frequencies. Seven cutaneous squamous cell carcinoma cell lines and five other types of cancer cell lines were used to detect the effect of nsPEF in vitro. Rate of cell death in these 12 different cancer cell lines was dependent on nsPEF voltage and pulse number. To examine the effect of nsPEF in vivo, carcinogen-induced cutaneous papillomas and squamous cell carcinomas in mice were exposed to nsPEF with three pulse numbers (50, 200, and 400 pulses, two nominal electric fields (40 KV/cm and 31 KV/cm, and two pulse durations (7 ns and 14 ns. Carcinogen-induced cutaneous papillomas and squamous carcinomas were eliminated efficiently using one treatment of nsPEF with 14 ns duration pulses (33/39 = 85%, and all remaining lesions were eliminated after a 2nd treatment (6/39 = 15%. 13.5% of carcinogen-induced tumors (5 of 37 were eliminated using 7 ns duration pulses after one treatment of nsPEF. Associated with tumor lysis, expression of the anti-apoptotic proteins Bcl-xl and Bcl-2 were markedly reduced and apoptosis increased (TUNEL assay after nsPEF treatment. nsPEF efficiently causes cell death in vitro and removes papillomas and squamous cell carcinoma in vivo from skin of mice. nsPEF has the therapeutic potential to remove human squamous carcinoma.

    Sullivan, Christopher; Curtis, Stuart; Mouzakes, Jason

    2017-02-01

    Recurrent Respiratory Papillomatosis (RRP) is a condition characterized by recurring squamous papillomas in the aerodigestive tract due to Human Papilloma Virus (HPV) infection. Treatment includes surgical debridement of the lesions often with adjuvant therapy. A newer adjuvant agent being tested is the HPV vaccine. The case report includes a child with RRP who underwent 10 surgeries in a year with an average inter-surgical interval (ISI) of 46 days. The patient then received the scheduled regimen of 3 doses of 9 valent HPV vaccine. Since beginning the vaccination, her average ISI increased to 113 days and as of writing of this paper only 1 surgery in the last 340 days. It is theorized that the increase in humoral response to the virus can slow the course of the disease, lengthen the ISI, and decrease morbidity. The results of this case report lends evidence to the use of the HPV vaccine as a therapeutic adjuvant therapy for RRP. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available The Human Papilloma Virus (HPV infection is now more common sexually transmitted diseases, with an incidence of 5.5 million worldwide, with 85% of the carrier of this virus adult population. Their oncogenic potential and increased oral lesions associated with oral HPV infection have led us to make a narrative of the literature on the role of HPV in oral cancer, especially types 16 and 18. Here we refer to the possible routes of infection, oncogenic mechanisms, both benign and potentially malignant oral lesions associated with the infection, different methods used for detection, prediction and prevention of infection. We stress the importance of the role of the dentist to identify individuals considered high risk and ease of performing detection in the oral cavity, through a quick and easy method as exfoliative cytology.

    Choroid plexus papilloma (CPP) is a highly vascular solid or mixed solid-cystic tumor. Previously described resection techniques for the more common solid CPP in the third ventricle have all been through the transcranial route. The authors review the literature and describe a patient who, to their knowledge, is the first successful resection of a large, completely solid CPP of the third ventricle through an entirely endoscopic, extended transphenoidal approach. Using modern neuroendoscopic methods and closure techniques, a gross total resection was accomplished and a successful closure without postoperative cerebrospinal fluid leak was achieved despite the presence of preoperative hydrocephalus. For appropriately selected lesions, an extended endonasal skull base resection can be performed successfully for vascular tumors despite the presence of preoperative hydrocephalus.

    This commentary explores the distribution of human papilloma virus (HPV) and HPV-related diseases, and factors affecting attitudes towards HPV, HPV-related diseases, and HPV vaccination in the Latin American Andean region. Lack of knowledge of HPV, known negative attitudes or incorrect assumptions about HPV, HPV-related diseases, and HPV vaccination provide a basis upon which to develop targeted HPV awareness and preventive health media campaigns. For maximal effect, media campaigns should use the internet, radio, and television to address health care providers, parents, and students. Additional programming can be developed for clinics to use in-house with their clients. Ministries of Education, Finance, and Health all have roles to play to increase national HPV, HPV-related diseases, and HPV vaccination awareness.

Lack of knowledge of HPV, known negative attitudes or incorrect assumptions about HPV, HPV-related diseases, and HPV vaccination provide a basis upon which to develop targeted HPV awareness and preventive health media campaigns. For maximal effect, media campaigns should use the internet, radio, and television to address health care providers, parents, and students. Additional programming can be developed for clinics to use in-house with their clients. Ministries of Education, Finance, and Health all have roles to play to increase national HPV, HPV-related diseases, and HPV vaccination awareness.

    We report the case of a patient who developed symptoms of acute cerebellar ataxia (ACA) after administration of the human papilloma virus (HPV)-16/18 vaccine. This patient developed symptoms of ACA, including nausea, vertigo, severe limb and truncal ataxia, and bilateral spontaneous continuous horizontal nystagmus with irregular rhythm, 12 days after administration of the HPV-16/18 AS04-adjuvanted cervical cancer vaccine. After this, the patient received methylprednisolone pulse and intravenous immunoglobulin (IVIG) therapies as well as immunoadsorption plasmapheresis. Severe ACA symptoms did not improve after methylprednisolone pulse and IVIG therapies, but the patient recovered completely after immunoadsorption plasmapheresis. This temporal association strongly suggests that ACA was induced by the vaccination. Georg Thieme Verlag KG Stuttgart · New York.

    The polymerase chain reaction technique was applied in "real time" format to evaluate the occurrence rate and infection ratio of various genotypes of human papilloma of high carcinogenic risk in virus-positive women and contact persons. The examination sampling consisted of 738 women aged of 17-50 years. The examination results permitted to establish high percentage of infection of 546 patients (74%) by carcinogenic papilloma viruses. The analysis of detection rate of various genotypes of human papilloma of high carcinogenic risk established that the 56th and 16th types of high carcinogenic risk are revealed more often than others--in 33% and 15.4% correspondingly. In males, first place in occurrence rate is for those types of virus of human papilloma: the 56th n = 10 (33.3%), 16th n = 3 (10%), 45th n = 3 (10%), 51th n = 3 (10%). The rest of genotypes are detected in 3-7% cases.

    AIM: To look for the evidence of human papilloma virus (HPV) infection in esophageal squamous cell carcinomas (ESCC) and to investigate the potential role and epidemiology of HPV infection in the pathogenesis of esophageal carcinomas in Henan emigrants.METHODS: Papilloma virus (PV) and HPV were determined by UltrasensiveTM S-P immunohistochemistry (IHC)and in situ hybridization (ISH) in esophageal carcinoma tissues (82.cases) and the normal mucosa (40 cases).RESULTS: IHC revealed that the positive rate of PV was 75.0%, 68.18% and 72.5% respectively while the HPV (16/18-E6) positive rate was 45.0%, 36.36%, 37.5%,respectively in esophageal carcinoma tissue specimens from Henan emigrants,the local citizens and patients in Hubei Cancer Hospital. The PV and HPV (16/18-E6) were negative in all normal esophageal mucosa specimens. No correlation was found between HPV in esophageal squamous cell carcinoma tissues and in grade 1-3 esophageal squamous cell carcinoma cells. In situ hybridization showed that the HPV (16/18) DNA positive rate was 30.0%, 31.8%, 25.0%, respectively in the 3 groups of samples. No positive hybridization signal was found in 40 normal esophageal mucosa specimens. The positive rate of HPV (16/18) DNA in the esophageal carcinoma specimens was significantly higher than that in normal mucosa specimens (P< 0.05). The positive rate was not different among the 3 groups of esophageal carcinoma tissue specimens (P>0.05).CONCLUSION: HPV infection is high in esophageal carcinoma of Henan emigrants, local residents and patients in Hubei Cancer Hospital. HPV is closely related with esophageal squamous cell carcinoma. HPV infection may play an important role in esophageal squamous cell carcinoma.

    Children presenting with recurrent fever may represent a diagnostic challenge. After excluding the most common etiologies, which include the consecutive occurrence of independent uncomplicated infections, a wide range of possible causes are considered. This article summarizes infectious and noninfectious causes of recurrent fever in pediatric patients. We highlight that, when investigating recurrent fever, it is important to consider age at onset, family history, duration of febrile episodes, length of interval between episodes, associated symptoms and response to treatment. Additionally, information regarding travel history and exposure to animals is helpful, especially with regard to infections. With the exclusion of repeated independent uncomplicated infections, many infective causes of recurrent fever are relatively rare in Western countries; therefore, clinicians should be attuned to suggestive case history data. It is important to rule out the possibility of an infectious process or a malignancy, in particular, if steroid therapy is being considered. After excluding an infectious or neoplastic etiology, immune-mediated and autoinflammatory diseases should be taken into consideration. Together with case history data, a careful physical exam during and between febrile episodes may give useful clues and guide laboratory investigations. However, despite a thorough evaluation, a recurrent fever may remain unexplained. A watchful follow-up is thus mandatory because new signs and symptoms may appear over time.

    Recurrent wheezing have a significant morbidity and it’s estimated that about one third of school-age children manifest the symptom during the first 5 years of life. Proper identification of children at risk of developing asthma at school age may predict long-term outcomes and improve treatment and preventive approach, but the possibility to identify these children at preschool age remains limited. For many years authors focused their studies to identify early children with recurrent wheezing at risk to develop asthma at school age. Different phenotypes have been proposed for a more precise characterization and a personalized plan of treatment. The main criticism concerns the inability to define stable phenotypes with the risk of overestimating or underestimating the characteristics of symptoms in these children. The aim of this review is to report the recent developments on the diagnosis and treatment of recurrent paediatric wheezing. PMID:26835404

    1988-08-01

    The incidence of recurrence of angular cheilitis following a successful antimicrobial treatment was studied in 48 patients. Clinical assessments including a microbial examination were carried out 8 months and 5 yr after termination of treatment. Eighty percent of the patients reported recurrence of their angular cheilitis on one or more occasions during the observation period. Patients with cutaneous disorders associated with dry skin or intraoral leukoplakia had an increased incidence of recrudescence. Neither the presence of denture stomatitis nor the type of microorganisms isolated from the original lesions of angular cheilitis, i.e. Candida albicans and/or Staphylococcus aureus, were associated with the number of recurrences. The present observations indicate that treatment of the majority of patients with angular cheilitis should be considered in a longer perspective than previously supposed, due to the short lasting therapeutic effects of the antimicrobial therapy.

  17. Recurrent Novae - A Review

    In recent years, recurrent nova eruptions are often observed very intensely in wide range of wavelengths from radio to optical to X-rays. Here I present selected highlights from recent multi-wavelength observations. The enigma of T Pyx is at the heart of this paper. While our current understanding of CV and symbiotic star evolution can explain why certain subset of recurrent novae have high accretion rate, that of T Pyx must be greatly elevated compared to the evolutionary mean. At the same time, we have extensive data to be able to estimate how the nova envelope was ejected in T Pyx, and it turns to be a rather complex tale. One suspects that envelope ejection in recurrent and classical novae in general is more complicated than the textbook descriptions. At the end of the review, I will speculate that these two may be connected.

    Full Text Available Recurrent parotitis is an uncommon condition in children. Its etiological factors have not been proved till date although causes due to genetic inheritance, local autoimmune manifestation, allergy, viral infection and immunodeficiency have been suggested. The exact management of this disorder is not yet standardized, but a conservative approach is preferred and all affected children should be screened for Sjogren′s syndrome and immune deficiency including human immunodeficiency virus. We report a 12 years female child who presented with 12 episodes of non-painful recurrent swellings of the bilateral parotid gland in the past 3 years.

    Pineoblastomas are rare, malignant, pineal region lesions that account for <0.1% of all intracranial tumors and can metastasize along the neuroaxis. Pineoblastomas are more common in children than in adults and adults account for <10% of patients. The management of pinealoblastoma is multimodality approach, surgery followed with radiation and chemotherapy. In view of aggressive nature few centres use high dose chemotherapy with autologus stem cell transplant in newly diagnosed cases but in recurrent setting the literature is very sparse. The present case represents the management of pinealoblastoma in the recurrent setting with reirradiation and adjuvant carmustine chemotherapy wherein the management guidelines are not definitive.

    1994-07-01

    We have examined the structures of replication intermediates from the human papillomavirus type 11 genome in DNA extracted from papilloma lesions (laryngeal papillomas). The sites of replication initiation and termination utilized in vivo were mapped by using neutral/neutral and neutral/alkaline two-dimensional agarose gel electrophoresis methods. Initiation of replication was detected in or very close to the upstream regulatory region (URR; the noncoding, regulatory sequences upstream of the open reading frames in the papillomavirus genome). We also show that replication forks proceed bidirectionally from the origin and converge 180circ opposite the URR. These results demonstrate the feasibility of analysis of replication of viral genomes directly from infected tissue.

    Mechanical small bowel obstructions caused by gallstones account for 1% to 3% of cases. In these patients, 80% to 90% of residual gallstones in these patients will pass through a remaining fistula without consequence. Recurrent gallstone ileus has been reported in 5% of patients. We report the case of a woman, aged 72 years, who presented with mechanical small bowel obstruction caused by gallstone ileus. After successful surgical therapy for gallstone ileus, the patient's symptoms recurred, and she was diagnosed with recurrent gallstone ileus requiring a repeat operation. While management of gallstone ileus can be achieved through a single-stage operation including enterolithotomy and cholecystectomy with repair of biliary-enteric fistula or by enterolithotomy alone, the literature supports enterolithotomy alone as the treatment of choice for gallstone ileus due to decreased mortality and morbidity. However, the latter approach does not obviate potential recurrence. We present this case of recurrent gallstone ileus to elucidate and review the pathogenesis, presentation, diagnosis, and consensus recommendations regarding management of this disorder.

    Full Text Available History, physical examination, simple laboratory and radiological tests, and endoscopic retrograde cholangiopancreatography (ERCP are able to establish the cause of recurrent acute pancreatitis in 70% to 90% of patients. Dysfunction of the biliary and/or pancreatic sphincter, as identified by sphincter of Oddi manometry, accounts for the majority of the remaining cases. The diagnosis may be missed if the pancreatic sphincter is not evaluated. Pancreas divisum is a prevalent congenital abnormality that is usually innocuous but can lead to recurrent attacks of acute pancreatitis or abdominal pain. In select cases, endoscopic sphincterotomy of the minor papilla can provide relief of symptoms and prevent further attacks. A small proportion of patients with idiopathic pancreatitis have tiny stones in the common bile duct (microlithiasis. Crystals can be visualized during microscopic analysis of bile that is aspirated at the time of ERCP. Neoplasia is a rare cause of pancreatitis, and the diagnosis can usually be established by computerized tomography or ERCP. A wide variety of medications can also cause recurrent pancreatitis. ERCP, sphincter of Oddi manometry, and microscopy of aspirated bile should be undertaken in patients with recurrent pancreatitis in whom the diagnosis is not obvious.

    Quick and parallel genotyping of human papilloma virus (HPV) type 16/18 is carried out by a specially designed giant magnetoimpedance (GMI) based microchannel system. Micropatterned soft magnetic ribbon exhibiting large GMI ratio serves as the biosensor element. HPV genotyping can be determined by the changes in GMI ratio in corresponding detection region after hybridization. The result shows that this system has great potential in future clinical diagnostics and can be easily extended to other biomedical applications based on molecular recognition.

    To present the results of recurrent respiratory papillomatosis (RRP) treatment with surgical excision and adjuvant anti-viral cidofovir intralesional use and to examine the correlation between the cidofovir effectiveness and the patient previous history of multiple larynx procedures, age, extension of lesion and dose. 32 patients with laryngeal papillomas were treated with cidofovir in our Department between I.2009 and I.2011. The number of previous RRP debulking procedures ranged from 1 to 100. The intensity of papillomatosis differed from one anatomic site and moderate growth to four or five localizations with heavy extension. The number of injections per patient varied from 1 to 7, and the total volume of 5 mg/ml solution varied from 2 to 33 ml. The injections were combined with laser debulking of the lesions. In disperse papillomata, the injections were administered in particular anatomical sites in 4-6 weeks intervals, in massive lesions injections were repeated in the same anatomical site in 2-4 weeks. Complete remission was observed in 18 out of 32 patients. 13 patients showed remission in a place of cidofovir injection. One patient did not react to the drug. In four patients, new changes in injection places appeared. In two patients, hepatic toxic side effects were observed. Intralesional cidofovir injection has been shown to be an effective and safe therapy for laryngeal papillomatosis and should be considered in those patients who experienced disease relapse.

    Human papilloma virus (HPV) is postulated as a risk factor in the etiology of some specific mucosal pathologies in the head and neck regions. Despite the frequent use of p16(INK4a) as a surrogate marker for HPV-infection, there is still controversy with respect to its reliability. This study has been undertaken to assess the potential role of p16(INK 4a) and Ki-67 expression in HPV-related lesions. The study was conducted on 71 specimens of oral, tonsillar and laryngeal lesions which comprised 25 dysplasia and 46 papilloma specimens. Specimens were immunohistochemically stained for p16(INK4A) and Ki-67 proteins. HPV DNA was determined by one step multiplex polymerase chain reaction. HPV DNA was detected in 33.8% of all lesions. Tonsil and larynx lesions showed significant differences with oral lesions for HPV positivity (p < 0.001). p16(INK 4a) over-expression was seen in 56.5% of papilloma and 60% of dysplasia specimens. HPV status showed a positive correlation with p16(INK 4a) expression in tonsillar dysplasias (p < 0.001). p16(INK 4a) expression may have a value as a marker in high risk HPV induced dysplasias, but not in low risk infected lesions. The proliferation index is not related to HPV-induced lesions and may be evaluated as an independent marker in head and neck premalignant lesions.

    In present investigation, etiopathological characterization of upper gastrointestinal tract (GIT) tumours of cattle and buffaloes was undertaken. A total of 27 GIT wart-like lesions in rumen, reticulum, mouth and oesophagus of cattle and buffaloes revealed the presence of small nodular to larger spherical or slender growths with thin base present on mucosa and ruminal pillar. Histopathologically, these cases were diagnosed as fibropapilloma/papilloma. This is the first world record on ruminal papillomatosis in buffaloes. Ruminal warts of cattle and buffaloes revealed the presence of BPV-5, -1 & -2, which is the first report of presence of these BPVs in the ruminal warts from India. Quantitative real-time PCR revealed that DNA samples of different GIT wart-like lesions contained varying amount of BPV DNA copy numbers. Immunohistochemistry revealed that the PCNA and Ki67 immunopositivity was present in the basal and spinosum layer of the fibropapilloma/papilloma, indicating these as the cellular proliferation site. In conclusion, the present investigation revealed that BPV-5, -1 & -2 are associated with certain ruminal wart-like lesions/growths in cattle and buffaloes, and the basal and spinosum layer of the ruminal fibropapilloma/papilloma were cellular proliferation sites.

    2014-12-01

    Recurrent respiratory papillomatosis is a viral induced disease characterised by exophytic epithelial lesions affecting the larynx. The problem with its treatment is the high recurrence of papilloma growth after surgical removal. The aim of our review is to analyse the actual use of cidofovir, an agent used in adjuvant therapy. We have reviewed 6 manuscripts that included a total of 118 patients. The parameters taken into account were: concentration of infiltrated cidofovir (mg/ml), therapeutic response, relapse-free time (months), side effects, genotypes (HPV-6/11/18) and evolution of dysplasia. Cidofovir was injected at concentrations from 2.5 to 15 mg/ml, therapeutic response was from 56.25% to 82.3% and relapse-free time was from 10.05 to 49 months. There were 2 cases of dysplasia during therapy. Ten patients had been infected by HPV-6, 4 patients by HPV-11 and 10 patients by HPV-6 and HPV-11. The purposes of our review include the following: to stress that the juvenile form is more aggressive than other forms, to demonstrate than the drug has good adjuvant action although it does not significantly change the final response to the disease, to show that side effects are modest and, finally, to disprove the hypothesis that cidofovir may promote evolution towards dysplasia. In conclusion, combination of surgical removal and injection of cidofovir is associated with good response in recurrent respiratory papillomatosis.

    2006-05-01

    We propose an extension of the recurrence plot concept to perform quantitative analyzes of roughness and disorder of spatial patterns at a fixed time. We introduce spatial recurrence plots (SRPs) as a graphical representation of the pointwise correlation matrix, in terms of a two-dimensional spatial return plot. This technique is applied to the study of complex patterns generated by coupled map lattices, which are characterized by measures of complexity based on SRPs. We show that the complexity measures we propose for SRPs provide a systematic way of investigating the distribution of spatially coherent structures, such as synchronization domains, in lattice profiles. This approach has potential for many more applications, e.g., in surface roughness analyzes.

    The long-term evolution of epidemic processes depends crucially on the structure of contact networks. As empirical evidence indicates that human populations exhibit strong community organization, we investigate here how such mesoscopic configurations affect the likelihood of epidemic recurrence. Through numerical simulations on real social networks and theoretical arguments using spectral methods, we demonstrate that highly contagious diseases that would have otherwise died out rapidly can persist indefinitely for an optimal range of modularity in contact networks.

    A 6-year-old female spayed Chihuahua was presented for the evaluation of generalized pigmented cutaneous masses, one of which was present on the lower right eyelid. The dog was not on immunosuppressive medications and did not have historical or laboratory evidence of underlying endocrine disease, including hypothyroidism and hyperadrenocorticism. Histopathology, immunohistochemistry, and polymerase chain reaction of a cutaneous biopsy from the left antebrachium containing representative lesions confirmed viral papillomatosis. Additionally, histopathology of the antebrachial mass revealed regions of epithelial dysplasia suggestive of possible early transformation to malignancy. Over the course of 5 months, the mass on the right lower eyelid progressed to encompass and efface the majority of the eyelid margin. Additionally, the eyelid tumor had changed from an ovoid, brown pigmented mass to an irregular, flesh-colored mass. At the dog's last recheck examination, a corneal ulcer had developed beneath the irregular dorsal margin of the tumor. Histopathology of the eyelid mass was consistent with squamous cell carcinoma (SCC) and was positive for the presence of papillomavirus using polymerase chain reaction. This report describes the transformation of a putative viral eyelid papilloma into a malignant SCC in an adult dog.

    Full Text Available Purpose: Women with human papilloma virus (HPV associated cervical neoplasia have a higher risk of developing breast cancer than the general female population. The purpose of this study was to (i identify high risk for cancer HPVs in cervical neoplasia and subsequent HPV positive breast cancers which developed in the same patients and (ii determine if these HPVs were biologically active.Methods: A range of polymerase chain reaction (PCR and immunohistochemical techniques were used to conduct a retrospective cohort study of cervical precancers and subsequent breast cancers in the same patients. Results: The same high risk HPV types were identified in both the cervical and breast specimens in 13 (46% of 28 patients. HPV type 18 was the most prevalent. HPVs appeared to be biologically active as demonstrated by the expression of HPV E7 proteins and the presence of HPV associated koilocytes. The average age of these patients diagnosed with breast cancer following prior cervical precancer was 51 years, as compared to 60 years for all women with breast cancer (p for difference = 0.001. Conclusions: These findings indicate that high risk HPVs can be associated with cervical neoplasia and subsequent young age breast cancer. However these associations are unusual and are a very small proportion of breast cancers. These outcomes confirm and extend the observations of 2 similar previous studies and offer one explanation for the increased prevalence of serious invasive breast cancer among young women.

    Full Text Available Aim: Human papilloma viruses (HPVs are small DNA viruses that have been identified in periodontal pocket as well as gingival sulcus. High risk HPVs are also associated with a subset of head and neck carcinomas. HPV detection in periodontium has previously involved DNA detection. This study attempts to: (a Detect the presence or absence of high risk HPV in marginal periodontiun by identifying E6/E7 messenger RNA (mRNA in cells from samples obtained by periodontal pocket scraping. (b Detect the percentage of HPV E6/E7 mRNA in cells of pocket scrapings, which is responsible for producing oncoproteins E6 and E7. Materials and Methods: Pocket scrapings from the periodontal pockets of eight subjects with generalized chronic periodontitis were taken the detection of presence or absence of E6, E7 mRNA was performed using in situ hybridization and flow cytometry. Results: HPV E6/E7 mRNA was detected in four of the eight samples. Conclusion: Presence of high risk human papillomaviruses in periodontal pockets patients of diagnosed with chronic periodontitis, not suffering from head and neck squamous cell carcinoma in the present day could link periodontitis to HPV related squamous cell carcinoma. Prevalence studies are needed detecting the presence of HPV in marginal periodontium as well as prospective studies of HPV positive periodontitis patients are required to explore this possible link.

    Inverted papilloma (IP) is an uncommon disease which arises in the mucosal membrane of the nasal cavity and paranasal sinus. It has been proposed that human papillomavirus (HPV) is the causal agent in the pathogenesis of IP and plays a key role in the progression from benign IP to malignancy. As there are no prior studies that focus on an Iranian population, this study intended to characterize the prevalence of HPV types in benign and malignant forms of IP. In this retrospective study, we included a total of 40 IP patients [37 benign IP and 3 IP/squamous cell carcinoma (SCC)] who were referred to Amiralam Hospital in Tehran from 2004-2006. HPV was detected in 18.9% and 100% of IP and IP/SCC cases, respectively. In all HPV positive cases of IP and IP/SCC cases, HPV6/11 and HPV16/18 were detected, respectively. Therefore, HPV types were different between the IP and IP/SCC patients, and this difference was statistically significant (p = 0.002). This study suggests that HPV6 and 11 may be involved in the development of IP, but HPV16 and 18 likely play an important role in the progression from benign to malignant form of IP. Copyright © 2015.

    World Health Organization recommends that girls, ages 9-13 years, get the human papilloma virus (HPV) vaccine. Global Alliance for Vaccines Initiative, which provides low-cost vaccine to eligible countries, requires that an additional intervention to be offered alongside the vaccine. We systematically searched and assessed the published literature in lower- and middle-income countries to identify effective interventions. We conducted systematic searches of four databases: PubMed, EMBASE, Global Index Medicus Regional Databases, and Cochrane Reviews for effective adolescent health interventions that could be delivered with the HPV vaccine in the following areas: (1) iron and folic acid supplementation (iron alone or with folic acid); (2) voucher delivery and cash transfer programs; (3) hand washing and soap provision; (4) vision screening; (5) promotion of physical activity/exercise; (6) menstrual hygiene education; (7) sexual and reproductive health education; (8) human immunodeficiency virus prevention activities; and (9) condom promotion, condom use skill building, and demonstration. We found limited evidence of consistent positive impact. Iron supplementation reduced iron-deficiency anemia and raised serum ferritin levels. Promotion of physical activity lowered blood pressure and reduced weight gain. Sexual and reproductive health and human immunodeficiency virus interventions improved adolescent communication with adults but did not influence behavioral outcomes. Countries should consider locally relevant and proven interventions to be offered alongside the HPV vaccine. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    Expectations prior to needle-related procedures can influence individuals' decision making and compliance with immunization programmes. To protect from human papilloma virus (HPV) and cervical cancer, the immunization needs to be given before sexual debut raising interest for this study's aim to investigate how 11 to 12-year-old girls narrate about their expectations prior to HPV vaccination. A total of 27 girls aged 11 to 12 years participated in this qualitative narrative study by writing short narratives describing their expectations. The requirement for inclusion was to have accepted HPV vaccination. Data were subjected to qualitative content analysis. Findings showed the following expectations: going to hurt, going to be scared and going to turn out fine. The expectations were based on the girls' previous experiences, knowledge and self-image. The latent content revealed that the girls tried to transform uneasiness to confidence. The conclusion drawn from this study is that most girls of this age seem confident about their ability to cope with possible unpleasantness related to vaccinations. However, nurses need to find strategies to help those children who feel uneasy about needle-related procedures. © The Author(s) 2015.

    Background. Cervical cancer caused by human papilloma virus (HPV) though preventable has claimed the lives of many women worldwide. This study was embarked upon to evaluate the general knowledge and perceptions of Nigerian women on HPV, cervical cancer, and HPV vaccine. Methods. Structured questionnaires were administered to a cross section of 737 women randomly selected from the general population in two southwestern States of Nigeria. Statistical analysis was done using SPSS computer software version 16. A P value >0.05 was considered statistically significant. Results. One hundred and seventy-six (23.9%) of the respondents had knowledge of HPV; 474 (64.3%) are aware of cervical cancer but only 136 (18.5%) know that HPV causes cervical cancer. 200 (27.1%) are aware that there is an HPV vaccine while 300 (40.7%) had knowledge of Pap smear test. Two hundred and sixty (35.3%) of the respondents know that early detection of HPV can prevent cervical cancer and in spite of this, only 110 (14.9%) have taken the Pap smear test before while 151 (20.5%) are not willing to go for the test at all. Conclusions. There is therefore the need to create proper awareness on the HPV and its possible consequence of cervical carcinoma.

    Abstract The aim of the present study was to identify the sexual behavior, attitudes, beliefs, and knowledge on sexually transmitted infections (STIs) focused on human papilloma virus (HPV) in the Greek adolescent population. The participants were 4547 adolescents, a representative sample for Greek territory with a mean age of 17 years. After written permission from Greek ministry of education each student completed a questionnaire with 36 questions. The fields covered were demographic characteristics, sexual life data, and basic knowledge on HPV. In the present study, 43% and 75% of the participants knew about HPV or cervical cancer, while more than 6 out of 10 did not know the association between the 2. More than 60% of the participants could not answer correctly neither about HPV infection and cervical cancer frequency in sexually active women, nor about protection methods against HPV and cervical cancer. This study shows that the low vaccination coverage of the Greek population may be due to lack of information and awareness of the adolescents and their parents. It is our duty to increase our efforts in order to better educate the population and vaccinate the population as early as possible in their reproductive years. PMID:28072683

    Full Text Available Objectives: Oral cancer ranks third among all cancers in the Indian population. Human papilloma virus (HPV plays a significant role in oral carcinogenesis. Population-based subtype variations are present in the HPV prevalence. This study gives an emphasis on the parameters to be considered in formalin fixed paraffin embedded tissues for polymerase chain reaction (PCR-based research work. Materials and Methods: Cross-sectional study on archival paraffin-embedded tissue samples of oral squamous cell carcinoma (OSCC, epithelial dysplasia, and normal oral mucosa surrounding impacted tooth was amplified by PCR for the E6 gene of HPV type 16 and E1 gene of HPV type 18. Results: HPV 18 was positive in three OSCC cases. There was no statistically significant association of the positivity of HPV with the age, gender or habit. The HPV positive patients had a tobacco habit and were of a younger age group. Conclusion: The presence of HPV in carcinomatous tissue highlights the possible role of HPV in carcinogenesis and archival paraffin embedded tissue specimen can be used for this analysis. Recent studies on genomic analyses have highlighted that the HPV positive tumors are a separate subgroup based on genomic sequencing. The results of a larger retrospective study will help further in our understanding of the role of HPV in carcinogenesis, this study could form the baseline for such follow-up studies.

    Full Text Available BACKGROUND Persistent infection of high risk genotypes of human papilloma virus (hrHPV has been established as the etiological cause for cervical cancer, and the most prevalent genotypes that infect the cervical tissue are HPV-16 and HPV-18. However, HPV genotype profile has been shown to differ according to geographical distribution across the globe. The present study aimed to determine the HPV genotype distribution in cervical cancer patients from Bandung, Indonesia. METHODS During the period of July – November 2010 viral DNA was extracted from randomly chosen cervical cancer biopsies and subjected to genotype determination using the diagnostic linear array genotyping test (Roche. The distribution of HPV genotypes was explored and the prevalence of HPV genotypes was mapped. RESULTS Of 96 cervical cancer tissue samples, 76 (79.2% were histopathologically classified as squamous cell cervical carcinoma. Due to the high cost of HPV genotyping tests, only twenty-five samples were randomly genotyped. Almost 90% of the cervical cancer patients were multiply infected with HPV-16 in combination with HPV-18, HPV-45, or HPV-52. The HPV-16 genotype had the highest prevalence, all samples being infected with HPV-16. CONCLUSION The cervical cancer cases were predominantly infected by multiple hrHPVs with HPV-16 as the major genotype among other hrHPVs, supporting the carcinogenic role of this hrHPV. Therefore, screening for hrHPVs in the general population is urgently needed as a means of early detection of cervical cancer.

    The present case report describes the presence of a persistent dysarthria and dysphagia as a consequence of surgical intervention for a choroid plexus papilloma (CPP). WM was a nine year ten month old male who at the time of the present study was seven years post-surgery. A comprehensive perceptual and instrumental test battery was used to document the nature of the dysarthria incorporating all components of speech production including respiration, phonation, resonance, articulation, and prosody. The nature of the dysphagia was evaluated through the use of videofluoroscopic evaluation of swallowing (VFS). Assessments confirmed the presence of a LMN dysarthria, marked by deficits in phonation, respiration, and prosody. Dysphagia assessment revealed deficits in oral preparatory, oral and pharyngeal stages of the swallow. The presence of persistent dysarthria and dysphagia in this case has a number of important implications for the management of children undergoing surgery for fourth ventricle CPPs, in particular the need for appropriate treatment, as well as counselling prior to surgery of the possible negative outcomes related to speech and swallowing.

    Full Text Available Background: Carcinomas of esophagus, mostly squamous cell carcinomas, occur throughout the world. There are a number of suspected genetic or environmental etiologies. Human papilloma virus (HPV is said to be a major etiology in areas with high incidence of esophageal carcinoma, while it is hardly detectable in low incidence regions. This study was designed to evaluate the prevalence of HPV in esophageal squamous cell carcinoma (ESCC cases diagnosed in Pathology Department, Medical School, Shiraz University of Medical Sciences.Methods: DNA material for PCR amplification of HPV genome was extracted from formalin-fixed paraffin-embedded tissue blocks of 92 cases of ESCC, diagnosed during 20 years from 1982 to 2002. Polymerase chain reaction was performed for amplification and detection of common HPV and type specific HPV-16 and HPV-18 genomic sequences in the presence of positive control (HPV-18 and HPV positive biopsies of uterine exocervix and additional internal controls i.e. beta-globin and cytotoxic T lymphocyte antigen 4 (CTLA4.Result: Good amplification of positive control and internal controls was observed. However, no amplification of HPV genome was observed.Conclusion: There is no association between HPV infection and the development of esophageal squamous cell carcinoma in the cases evaluated.

    Full Text Available Background: Cervical cancer is the second leading cause of cancer death among women. In this cancer, the effects of prevention, early diagnosis and treatment more than other cancers decrease the mortality rate. In 1970 human papilloma virus (HPV was introduction as major etiologic factor of cervical cancer. Different studies throughout the world revealed strong correlation between HPV and cancerous & precancerous changes in epithelial cells. Since cell culture and serological methods can not recognize the virus and its subtypes, the importance of the molecular methods including polymerase chain reaction (PCR in early and definite diagnosis of virus is obvious. Methods: In this study, after patient selection using the related protocol and completion of the questionnaires, 100 samples from cancer lesions of cervix selected. Then DNA extraction from paraffin blocks performed using standard method. Multiplex PCR with two pairs of primer (one as internal control performed and the PCR product run on 8% polyacrylamid gel. Results: The results showed that 73% of the tissues were infected by HPV. Conclusion: This finding confirm the previous results based of correlation between HPV,and cervical cancer.

    2012-04-01

    There is currently strong evidence supporting human papilloma virus (HPV) causation in a distinct disease entity of oropharyngeal cancer (OPC), with an increasing incidence worldwide.This review aims to critically analyse whether a change in our management approaches to HPV-positive OPC is now required for this increasingly significant public health concern. HPV-positive OPC appears to have increased worldwide. HPV status has a strong prognostic effect, and, in combination with smoking status, primary, and nodal stage, is useful in the risk stratification of OPC. HPV-positive OPC responds better to chemoradiotherapy, surgery, and postoperative chemoradiotherapy than HPV-negative tumours, with improved survival outcomes. There remain concerns regarding the efficacy of HPV detection assays in clinical practice. HPV-negative head and neck cancer still accounts for the largest subset of patients that we treat and carries poor survival outcomes. It is currently not advisable to change management for either HPV-positive or HPV-negative OPC as there is a lack of high-quality evidence to support this. High-quality randomized controlled trials are required to assess the efficacy of the different treatment modalities currently available for both HPV-positive and HPV-negative OPC.

    Esophageal verrucous carcinoma is a rare variant of esophageal squamous cell carcinoma. We report a case of esophageal verrucous carcinoma associated with human papilloma virus (HPV) type 51. The patient had long-standing dysphagia and odynophagia, and white esophageal plaques showing hyperkeratosis on biopsy. At repeat endoscopy, the esophagus was covered with verrucous white plaques and areas of nodular mucosa with white fronds, with a distal 10-cm smooth mass protruding into the lumen. Biopsies demonstrated an atypical squamoproliferative lesion but no frank malignancy. HPV type 51 DNA was detected in endoscopic biopsy specimens by polymerase chain reaction. Because the size of the lesion favored an underlying verrucous carcinoma, our patient underwent minimally invasive esophagectomy with gastric pull-up and cervical anastomosis. The pathologic diagnosis was a well-differentiated esophageal verrucous carcinoma. One year after esophagectomy, the patient feels well and is free of disease. Although HPV DNA was not detected in the cancer tissue obtained at surgery, our case suggests an association between HPV type 51 and esophageal verrucous carcinoma. The clinical evolution in this case highlights the importance of endoscopic surveillance in patients with exuberant esophageal hyperkeratosis, and of definitive surgical resection when malignancy is suspected even if frank malignancy is not demonstrated on superficial biopsies.

    Full Text Available Papiloma invertido (PI corresponde a 0,5%-4% dos tumores nasais benignos. A importância está na agressividade local, taxa de recorrência elevada e possibilidade de transformação maligna. O tratamento é controverso, encontrando melhor suporte na cirurgia endoscópica. OBJETIVO: Descrever aspectos clínico-epidemiológicos e tratamento dos casos de PI de um hospital terciário. CASUÍSTICA E MÉTODO: Estudo retrospectivo, realizado por revisão de prontuários de 26 pacientes com diagnóstico de PI nasal, avaliando localização tumoral, estadiamento clínico, tempo de seguimento, recidiva tumoral, malignidade, tipo de cirurgia realizada e complicações pós-operatórias. RESULTADO: Na casuística, havia 13 homens e 13 mulheres, com idade média de 57,8 anos. O tempo médio de seguimento foi de 29,4 meses, com 7,6% de taxa de recidiva. Houve predomínio de tumores T3 e T4 e 3,8% de taxa de malignidade. Todos foram submetidos a tratamento cirúrgico, predominando a cirurgia endoscópica endonasal. CONCLUSÃO: O PI é um tumor nasal originado principalmente na parede lateral nasal, mas também acomete seios paranasais. Avanços na cirurgia endoscópica vêm ganhando destaque pela menor invasividade e taxas de sucesso semelhantes às técnicas tradicionais externas, permitindo a exérese completa do tumor e proporcionando menor taxa de recidiva e tratamento completo no caso de malignidade.Inverted papilloma (IP comprises 0.5-4% of benign nasal tumors.

    In this paper, we propose a new method of multiscale recurrence quantification analysis (MSRQA) to analyze the structure of order recurrence plots. The MSRQA is based on order patterns over a range of time scales. Compared with conventional recurrence quantification analysis (RQA), the MSRQA can show richer and more recognizable information on the local characteristics of diverse systems which successfully describes their recurrence properties. Both synthetic series and stock market indexes exhibit their properties of recurrence at large time scales that quite differ from those at a single time scale. Some systems present more accurate recurrence patterns under large time scales. It demonstrates that the new approach is effective for distinguishing three similar stock market systems and showing some inherent differences.

    Full Text Available Antiphospholipid antibodies (APA are associated with thrombosis, thrombocytopenia and fetal loss but they occur in a variety of diseases. Despite many efforts, a correlation between the specificity of particular subgroups of APA and particular clinical situations remains to be established. The antigens at the origin of APA remain to be identified. We discuss here the possible links between cell apoptosis or necrosis, leading to plasma membrane alterations, and the occurrence of APA in response to sustained stimulation. The pathogenic potential of APA is also considered with respect to recurrent pregnancy loss.

    Miller Fisher syndrome (MFS) is a variant of Guillan Barre syndrome characterized by the triad of ophthalmoplegia, ataxia and areflexia. Recurrences are exceptional with Miller Fisher syndrome. We are reporting a case with two episodes of MFS within two years. Initially he presented with partial ophthalmoplegia, ataxia. Second episode was characterized by full-blown presentation characterized by ataxia, areflexia and ophthalmoplegia. CSF analysis was typical during both episodes. Nerve conduction velocity study was fairly within normal limits. MRI of brain was within normal limits. He responded to symptomatic measures initially, then to steroids in the second episode. We are reporting the case due to its rarity.

    We examine relationships between two minors of order n of some matrices of n rows and n+r columns. This is done through a class of determinants, here called $n$-determinants, the investigation of which is our objective. We prove that 1-determinants are the upper Hessenberg determinants. In particular, we state several 1-determinants each of which equals a Fibonacci number. We also derive relationships among terms of sequences defined by the same recurrence equation independently of the initial conditions. A result generalizing the formula for the product of two determinants is obtained. Finally, we prove that the Schur functions may be expressed as $n$-determinants.

    Bed bugs, Cimex lectularius, irradiated with gamma rays were allowed to suck blood from shaved areas of the skin of rabbits, Oryctolagus cuniculus, 2 times/week for 5 months and then once weekly for another 5 months. This significantly induced the formation of skin papillomas and sweat gland hyperplasia in five out of nine experimental animals. It is speculated that the saliva of the irradiated bugs was activated by gamma rays and was responsible for the induction of skin papillomas. Because bed bugs play a significant role in the transmission of virus, it is also speculated that there is a virus in the saliva of bugs; this virus may be activated by gamma radiation and causes the development of papillomas in the skin.

    1991-01-01

    A model for a class of high-capacity associative memories is presented. Since they are based on two-layer recurrent neural networks and their operations depend on the correlation measure, these associative memories are called recurrent correlation associative memories (RCAMs). The RCAMs are shown to be asymptotically stable in both synchronous and asynchronous (sequential) update modes as long as their weighting functions are continuous and monotone nondecreasing. In particular, a high-capacity RCAM named the exponential correlation associative memory (ECAM) is proposed. The asymptotic storage capacity of the ECAM scales exponentially with the length of memory patterns, and it meets the ultimate upper bound for the capacity of associative memories. The asymptotic storage capacity of the ECAM with limited dynamic range in its exponentiation nodes is found to be proportional to that dynamic range. Design and fabrication of a 3-mm CMOS ECAM chip is reported. The prototype chip can store 32 24-bit memory patterns, and its speed is higher than one associative recall operation every 3 mus. An application of the ECAM chip to vector quantization is also described.

    Papillomaviruses (PVs) induce papillomas, premalignant lesions, and carcinomas in a wide variety of species. PVs are classified first based on their host and tissue tropism and then their genomic diversities. A laboratory mouse papillomavirus, MmuPV1 (formerly MusPV), was horizontally transmitted within an inbred colony of NMRI-Foxn1nu/Foxn1nu (nude; T cell deficient) mice of an unknown period of time. A ground-up, filtered papilloma inoculum was not capable of infecting C57BL/6J wild-type mice; however, immunocompetent, alopecic, S/RV/Cri-ba/ba (bare) mice developed small papillomas at injection sites that regressed. NMRI-Foxn1nu and B6.Cg-Foxn1nu, but not NU/J-Foxn1nu, mice were susceptible to MmuPV1 infection. B6 congenic strains, but not other congenic strains carrying the same allelic mutations, lacking B- and T-cells, but not B-cells alone, were susceptible to infection, indicating that mouse strain and T-cell deficiency are critical to tumor formation. Lesions initially observed were exophytic papillomas around the muzzle, exophytic papillomas on the tail, and condylomas of the vaginal lining which could be induced by separate scarification or simultaneous scarification of MmuPV1 at all four sites. On the dorsal skin, locally invasive, poorly differentiated tumors developed with features similar to human trichoblastomas. Transcriptome analysis revealed significant differences between the normal skin in these anatomic sites and in papillomas versus trichoblastomas. The primarily dysregulated genes involved molecular pathways associated with cancer, cellular development, cellular growth and proliferation, cell morphology, and connective tissue development and function. Although trichoepitheliomas are benign, aggressive tumors, few of the genes commonly associated with basal cell carcinoma or squamous cells carcinoma were highly dysregulated. PMID:25474466

    Full Text Available The cervical cancer is one of the most common diseases in world. This malignancy is the seventh highest prevalence oncological disease worldwide and the second highest prevalence oncological disease of women in the world. Meanwhile women need to be infected by human papilloma virus (HPV is absolutely necessary for it further evolution, HPV DNA was found in 99.97% cases of disease. Except cervical cancer, HPV cause 85% of rectal cancer, 50% of the vulva, vagina and penis cancers, 20% of oropharyngeal cancer and 10% of larynx and esophagus cancers. In 2009, 14 000 women were diagnosed with cervical cancer in Russia. The growth in morbidity was 19% (in comparison with 1999. The most effective recognised measure for almost each infection prophylaxis is a vaccination. Two human papilloma virus vaccines are available in Russia nowadays — Gardasil and Cervarix, produced in Belgium and the Netherlands respectively. Cervarix is a bivalent vaccine based on virus-like particles (VLP of two types. Recombinant major capsid proteins L1 HPV 16 and HPV 18 express in baculovirus expression system and self-assembled into virus-like particles (about 70 percent of cervical cancers are caused by HPV 16 and HPV 18. VLP of each strain produced in different baculovirus vectors and then combined in single drug. Gardasil is like Cervarix with few exceptions. Producing organisms are fungi S. cerevisiae in this case, and this vaccine contains low-risk HPV 6 and HPV 11 VLP. Thus, Gardasil is quadrivalent HPV-6/11/16/18 vaccine. These vaccines are very effective in averting infection of disease and don’t have significant side-effects, however they have some disadvantages. Firstly, they have a high price because of necessity of their expression in eukaryotic cells. Secondly, they are strain-specific, so vaccines are completely effective only for virus’s strains which are represented in the vaccine. Thirdly, it`s the absence of therapeutic (treatment of established

    Full Text Available Background: Previous studies demonstrated the etiological role of human papilloma virus (HPV in cervical carcinogenesis. Assessing the distribution of HPV may elucidate these observations. Materials and Methods: In total, we examined 3839 specimens, of which 187 abnormally classified cervical smears were immunostained using the p16 INK4A assay. DNA was extracted from 182 specimens, and polymerase chain reaction (PCR was performed. Participants′ socio-demographics, sexual and reproductive history, HIV status, contraceptive use, and Pap smear history were recorded. Results: Subject ages, number of sexual partners, and age at first sexual encounter ranged from 15 to 49 years, from 1 to 37 partners, and from 13 to 34 years, respectively. P16 immunoreactivity was detected in 60.4% of cases. The distribution of epithelial lesions and P16 overexpression (bracketed was: 28 (5 atypical squamous cells of undetermined significance (ASC-US, 96 (50 lower grade squamous intraepithelial lesion (LSIL, 9 (7 atypical squamous cells-cannot exclude HSIL (ASC-H, and 54 (51 higher grade squamous intraepithelial lesion (HSIL. Ninety-four percent of HSIL expressed P16. Fifty-two percent of LSIL expressed P16. P16 expression declined from 61% (25-34 year age group to 5% (45-49 year age group for different age groups. HPV-DNA by PCR was detected in 94.5% of P16-positive samples. Type-specific PCR (HPV 16 and 18 was found in 12.2% and 14.5% of abnormal lesions, respectively. Younger age at first sexual encounter and HIV infection predominated in HPV type(s 16 and/or 18 positive subjects. Conclusion: This study reinforced the value of the p16 INK4A surrogate marker in identifying women with progressive cervical disease.

    AIM: To investigate the presence of high-risk human papilloma virus (HPV) in esophageal squamous cell carcinomas (ESCCs) in a non-selected Mexican population.METHODS: Cases with a pathological diagnosis of squamous cell carcinoma of the esophagus were obtained from Department of Pathology files, at the National Cancer Institute in Mexico City during the period between 2000 and 2008. Slides from each case were reviewed and cases with sufficient neoplastic tissue were selected for molecular analysis. DNA was extracted from paraffin-embedded tissue samples for polymerase chain reaction analysis to detect HPV DNA sequences. Demographic and clinical data of each patient were retrieved from corresponding clinical records.RESULTS: HPV was detected in 15 (25%) of ESCCs. HPV-16 was the most frequently observed genotype, followed by HPV-18; HPV-59 was also detected inone case. Unfortunately, HPV genotype could not be established in three cases due to lack of material for direct sequencing, although universal primers detected the presence of HPV generic sequences. No low-risk HPV genotypes were found nor was HPV-16/18 co-infection. HPV presence in ESCC was not significantly associated with gender, age, alcohol consumption, smoking, anatomic location, or histologic grade. All patients belonged to low and very low socioeconomic strata, and were diagnosed at advanced disease stage. Male patients were most commonly affected and the male:female ratio in HPV-positive ESCC increased twofold in comparison with HPV-negative cases (6.5:1 vs 3.1:1).CONCLUSION: High prevalence of high-risk HPV in ESCC in Mexico does not support the hypothesis that HPV-associated ESCC is more common in areas with higher ESCC incidence rates.

    Ethanol, human papilloma virus (HPV), and poor oral hygiene are risk factors that have been attributed to oral carcinogenesis. Streptococci sp and HPV infections are common in the head and neck, often associated with sexual activity. Although HPV is linked to head and neck squamous cell carcinoma, it is unclear whether there is a similar role for Streptococci sp. This cell study examines whether Streptococci sp and HPV-16 with exposure to ethyl alcohol (ETOH) can act as cofactors in the malignant transformation of oral keratinocytes. ETOH (0.1%-20% vol/vol) was used to investigate Streptococci sp attachment with immortalized E6-expressing HPV/HOK-16B cells, human oral buccal keratinocytes, and foreskin keratinocytes. Streptococci sp (Streptococci mutans [LT11]) and various strains of acetaldehyde (AA) producer and nonproducer Streptococcus salivarius (110-1, 109-2, 101-7, and 107-1) and a lactic acid producer bacterium, Lactobacillus rhamnosus (24-1 and 25-2), were examined for interactions with keratinocytes by use of a green dye (percent of cells with colonies after 24 hours). Carcinogens, AA, malondialdehyde, DNA damage, and proliferation (5'-bromo-2-deoxyuridine) among keratinocytes were also quantified. AA and malondialdehyde production from permissible Streptococci sp significantly increased with attachment to keratinocytes, whereas L rhamnosus did not significantly attach to keratinocytes. This attachment was associated with enhanced levels of AA adduct formation, proliferation (5'-bromo-2-deoxyuridine incorporation), and enhanced migration through integrin-coated basement membrane by HPV oral keratinocytes, which are characteristics of a malignant phenotype. These cell studies suggest that oral Streptococci sp and HPV (HPV-16) cooperate to transform oral keratinocytes after low-level ETOH (1%) exposure. These results appear to suggest a significant clinical interaction, but further validation is warranted. Copyright © 2012 American Association of Oral and

    Full Text Available Background: Human papilloma virus (HPV is regarded as the main cause in the etiology of cervical cancer. The purpose of our study is to assess the knowledge of medical students about HPV vaccine and to evaluate their opinion on this subject.   Material and Method: The study population consisted of 488 medical students. The survey was composed of questions intended   to obtain information about transmission route of HPV, types of HPV, role of HPV in cervical cancer, whether HPV is treatable or not, which types of HPV the HPV vaccine prevents, the age groups HPV vaccine is administered, the opinions on HPV vaccine and sufficiency of public health, whether female students have underwent vaccination and if not what their drawbacks are.   Results: Mean age of the students participating in the study was 21±4 and 58 % of the patients were female. Out of 448 medical students, 60% of them did not know that HPV was a sexually transmitted disease. Only 55% students knew about the association of HPV with cervical cancer and 52% participants stated that HPV vaccine could not be preventive against cervical cancer. None of female students had been immunized and 67% of female students did not consider getting immunized. Among those who did not consider getting immunized, 70% said they had worries about the safety of the vaccine. Conclusion: Our study results revealed that the knowledge of medical students about HPV is satisfactory, however their knowledge about HPV vaccine, immunization status and desire to be immunized were little.

    Background: Infection with human papilloma virus (HPV) is the main cause of cervical cancer, but the local risk factors have not been sufficiently assessed. Aim: The study is aimed at determining the prevalence and to evaluate the local risk factors of HPV infection in cervical smears at the Imo State University Teaching Hospital, Orlu, Nigeria. Subjects and Methods: The participants involved 445 randomly selected sexually active women attending the antenatal, postnatal, gynecology and family planning clinics in the Department of Obstetrics and Gynecology of the university between April 2004 and May 2012. A questionnaire assessing various socio-demographic characteristics of the participants was administered. The pap smears of the participants were examined microscopically for evidence of HPV infection. The SPSS version 17.0 (Chicago, Illinois, USA) was used to compute and analyze the results. The results were presented in tables as simple percentages. Tests of significance using the Chi-square and fisher exact tests were applied where appropriate. Results: The prevalence rate of HPV was 10.3%. The peak age-specific prevalence of 11.7% occurred in the 15-19 years age group. There were significant associations between the occurrence of HPV and multiple sexual partners, coital frequency, multiparity, contraceptive use, marital status, low socio-economic status, abnormal vaginal discharge, irregular menstruation, post-coital and post-menopausal bleeding, (P < 0.05). Conclusion: All sexually active women including teenagers should be screened for cervical HPV infection in an organized systematic program equipped with a good call and recall system. There is, therefore, a need to move emphasis from the current practice of opportunistic screening to a systematic screening of the whole population at risk despite cost implications. PMID:24380003

    Human papilloma viruses (HPV) are strong human carcinogens, in fact today they are considered as the second most frequent carcinogen. In the middle of the 1970s the hypothesis that cervical cancer may arise from viruses was established and in the 1990s the relationship between HPV and cervical neoplasia was confirmed. HPV infections are the most common sexually transmitted infections. Specific subtypes of human papilomaviruses are now considered as the etiological agents in nearly all cases of cervical cancer and cervical epithelial neoplasia. Approximately 470,000 new cases and 23,000 deaths of cervical cancer occur each year, with the majority taking place in developing countries. Cervical cancer remains among the three leading causes of cancer deaths among women below the age of 45. Human papilomaviruses are classified into two groups: high-risk (oncogenic) types and low risk types. HPV types 16, 18, 45 and 31 are considered to be the most important oncogenic types. Subtypes 16 and 18 are the causative agents of more than 50% of cervical pre-cancerous lesions, and more than 70% of cervical cancer cases. High risk subtypes are also implicated with anal, perianal and oropharyngeal carcinomas. Recently, the prophylactic bivalent HPV 16/18 and the quadrivalent HPV 6/11/16/18/ vaccines have been approved. The development of prophylactic vaccines against human papilomavirus has been hailed as one of the most significant advances of recent years and it is expected to reduce dramatically the mortality of human papilomavirus associated cancers, but has also given rise to some of the most intense scientific debates.

  15. Basics of tumor development and importance of human papilloma virus (HPV for head and neck cancer [

    Directory of Open Access Journals (Sweden)

    Klussmann, Jens Peter

    2012-12-01

    Full Text Available [english] Head and Neck Squamous Cell Carcinomas (HNSCC are the 6 most common cancers worldwide. While incidence rates for cancer of the hypopharynx and larynx are decreasing, a significant increase in cancer of the oropharynx (OSCC is observed. Classical risk factors for HNSCC are smoking and alcohol. It has been shown for 25 to 60% of OSCC to be associated with an infection by oncogenic human papilloma viruses (HPV. The development of “common” cancer of the head and neck is substantially enhanced by an accumulation of genetic changes, which lead to an inactivation of tumor suppressor genes or activation of proto-oncogenes. A more or less uniform sequence of different DNA-damages leads to genetic instability. In this context, an early and frequent event is deletion on the short arm of chromosome 9, which results in inactivation of the p16-gene. In contrast, for HPV-induced carcinogenesis, expression of the viral proteins E6 and E7 is most important, since they lead to inactivation of the cellular tumor-suppressor-proteins p53 and Rb. The natural route of transoral infection is a matter of debate; peroral HPV-infections might be frequent and disappear uneventfully in most cases. Smoking seems to increase the probability for developing an HPV-associated OSCC. The association of HNSCC with HPV can be proven with established methods in clinical diagnostics. In addition to classical prognostic factors, diagnosis of HPV-association may become important for selection of future therapies. Prognostic relevance of HPV probably surmounts many known risk-factors, for example regional metastasis. Until now, no other molecular markers are established in clinical routine. Future therapy concepts may vary for the two subgroups of patients, particularly patients with HPV-associated OSCC may take advantage of less aggressive treatments. Finally, an outlook will be given on possible targeted therapies.

    30% of the patients presenting with epistaxis at emergency wards and otorhinolaryngeal specialist departments have posterior bleeding. Traditional treatment with packing often leads to initial treatment failure, and many patients experience recurrent bleeding within the following month. Recurrent posterior epistaxis should be treated with local electrocautery or endoscopic ligation of the sphenopalatine artery to reduce patient discomfort, hospital stay, risk of treatment failure and recurrence.

    1990-01-01

    This descriptive study of the perceptions and needs of people with recurrent malignancies asks three questions: How do patients describe the meaning of a recurrence of cancer? Do individuals perceive the diagnosis of recurrence and the initial diagnosis of cancer differently? What are the key psychosocial problems associated with recurrent cancer? The theoretical framework was based on Lazarus and Folkman's theory of stress, appraisal, and coping. Subjects completed the Impact of Event Scale (IES), the Psychosocial Adjustment to Illness Scale--Self-Report (PAIS), and a semistructured qualitative interview. The interview elicited perceptions of the event of recurrence and differences between the diagnosis of recurrence and the initial diagnosis. The convenience sample included 40 patients diagnosed with recurrent cancer within the last 30 days. Many subjects (78%) reported that the recurrence was more upsetting than the initial diagnosis. Scores on both the IES and the PAIS were high when compared to normative samples of patients with cancer suggesting that this sample of patients experienced a lot of psychological distress as well as problems at home, work, and in their social lives. These concerns often were unknown to caregivers. Although more research is needed, the authors propose that, with more accurate assessment, more effective intervention could be implemented and the quality of life improved for patients with recurrent cancer.

    Full Text Available Venous thrombosis, including deep vein thrombosis and pulmonary embolism, is a common disease that frequently recurs. Recurrence can be prevented by anticoagulants, but this comes at the risk of bleeding. Therefore, assessment of the risk of recurrence is important to balance the risks and benefits of anticoagulant treatment. This review briefly outlines what is currently known about the epidemiology of recurrent venous thrombosis, and focuses in more detail on potential new risk factors for venous recurrence. The general implications of these findings in patient management are discussed.

    Full Text Available Abstract. Recurrent respiratory papillomatosis (RRP is the most frequently occurring tumour of the upper airways associated with a human papilloma virus (HPV. The aim of this study was to reveal some features of systemic and local immunity in RRP, to investigate clinical and immunological efficiency of local treatment with recombinant interferon-α (rIFNα, and to determine clinical and laboratory indications to it’s administration. The study included forty-one patients with confirmed RRP. Their examination included histological examination of papillomas, detection of HPV DNA in papilloma tissues using PCR technique, phenotyping of circulating lymphocytes (CD3+, CD4+, CD8+, CD25+, HLA-DR+ by means of flow cytometry. The levels of IFNγ, TNFα, GM-CSF, IL-2, IL-4, IL-5, IL-10, IL-12, IL-13 in laryngeal secretions were quantified by a multiplex immunoassay. In all cases, we revealed an initially decreased functional activity of Т-lymphocytes, as well as low contents of Т-killer and NK-cells. In laryngeal secretions, increased values of Th1-type-specific cytokines (IFNγ and TNFα were found. Besides that, high levels of local IL-4 were detected thus being typical to alternative Th2-type response. Single inhalations 1000 000 ME of «Interal» or «Roferon» preparations were administered daily (a total of 10-15 millions ME per therapeutic course. Thirteen patients received the treatment after surgery, as an adjuvant therapy, and eleven patients underwent monotherapy. Complete tumor regression of tumors following this monotherapy was observed in 45,5% of the patients, whereas partial regression was registered in 45%. The effect was mostly expressed in frequently recurring juvenile papillomatosis with aggressive course and histological pattern of actively proliferating papilloma. In the patients with complete tumor regression, high initial levels of TNFα and IL-4/IFNг ratios were revealed initially in laryngeal secretions. When rIFNб was

    2016-01-01

    Recurrent vulvovaginal candidiasis (RVVC) is a common cause of significant morbidity in women in all strata of society affecting millions of women worldwide. Previously, RVVC occurrence was limited by onset of menopause but the widespread use of hormone replacement therapy has extended the at-risk period. Candida albicans remains the dominant species responsible for RVVC, however optimal management of RVVC requires species determination and effective treatment measures are best if species-specific. Considerable progress has been made in understanding risk factors that determine susceptibility to RVVC, particularly genetic factors, as well as new insights into normal vaginal defense immune mechanisms and their aberrations in RVVC. While effective control of RVVC is achievable with the use of fluconazole maintenance suppressive therapy, cure of RVVC remains elusive especially in this era of fluconazole drug resistance. Vaccine development remains a critical challenge and need.

    2013-01-01

    Juvenile recurrent respiratory papillomatosis (JRRP) is an infectious disease caused by the growth of papillomas in the airway. Up to 4% of these cases degenerate into squamous cell carcinoma. We present the case of a 17-year-old female patient with JRRP in which the utility of (18)F-FDG-PET/CT in the characterization of suspicious papillomatous lesions of malignancy is evaluated. Morphometabolic techniques, CT scan and PET/CT scans were suggestive of malignancy. However, this was not confirmed in the histopathological analysis after its resection. The (18)F-FDG-PET/CT does not seem to be a useful tool for early detection of malignancy in JRRP. However, it does increase the diagnostic accuracy of the biopsy as it identifies the most active lesions and, therefore, those most likely to be malignant.

  5. A novel modification of the autoimplantation therapy for the treatment of multiple, recurrent and palmoplantar warts

    Directory of Open Access Journals (Sweden)

    K C Nischal

    2012-01-01

    Full Text Available Background: Ideal treatment for warts should be effective, safe, have less morbidity and provide long-lasting immunity against human papilloma virus. This can optimally achieved by the stimulation of the immune system against the virus. The autoimplantation of warts, autowart injection and quadrivalent vaccines have been used for this purpose. Autoimplanatation is a simple technique where the subcutis deep wart tissue is harvested as a donor and implanted into the uninvolved skin. However, this led to two wounds, at donor and recipient sites. Aim: The aim was to evaluate the safety and efficacy of a novel modification of autoimplantation therapy in the treatment of multiple, recurrent and palmoplantar warts. Subjects and Methods: Thirty-three patients with multiple, recurrent and palmoplantar warts were enrolled. Instead of taking a bit of the wart tissue, the donor tissue was harvested by paring the wart. The pared tissue was implanted deep into the subcutis by stab incision done using the same surgical blade no. 11. The resolution of all warts within 3 months after the procedure was considered successful. Patients with complete clearance were followed up for 1 month for any recurrence. Results: Out of 35 patients, 27 patients were available for follow-up. A total of 20 (74.1% patients showed a complete clearance of warts within 3 months. Partial clearance was seen in 1 patient. Erythematous nodules developed at the site of implantation in 3 (11.1% patients. There was relapse in one patient. Conclusion: A modified technique of autoimplantation of warts employing the pared stratum corneum tissue from the wart is a simple, effective, less traumatic and rapid procedure in the treatment of multiple, recurrent and palmoplantar warts.

    Full Text Available Context: Bacterial pathogens in dental plaque are necessary for the development of periodontitis but this etiology alone does not explain all its clinicopathologic features. Researchers have proven the role of certain viruses like herpes virus in periodontal disease which implies that other viral agents like human papilloma virus may also be involved. Aims: This cross-sectional study was conducted to determine the proportion of patients with human papilloma virus (HPV-16 in marginal periodontium by analyzing DNA from the gingival tissue sample and to understand its association with periodontitis. Settings and Design: 102 systemically healthy patients between the age group of 15 and 70 years reporting to the Department of Periodontology who required surgical intervention (flap surgery for patients with periodontitis and crown lengthening for healthy patients with internal bevel gingivectomy were selected. Materials and Methods: After scaling and root planning, gingival tissue was collected during the respective surgical procedure. DNA was isolated and amplified using specific primers for HPV-16 by polymerase chain reaction (PCR. The amplified products were checked by agarose gel electrophoresis. Results: No HPV DNA was detected in the 102 samples analyzed. Conclusion: Marginal periodontium does not contain HPV in this study population and hence there was no association between HPV and periodontitis.

    Human papillomavirus infection can cause a variety of benign or malignant oral lesions, and the various genotypes can cause distinct types of lesions. To our best knowledge, there has been no report of 2 different human papillomavirus-related oral lesions in different oral sites in the same patient before. This paper reported a patient with 2 different oral lesions which were clinically and histologically in accord with focal epithelial hyperplasia and oral papilloma, respectively. Using DNA extracted from these 2 different lesions, tissue blocks were tested for presence of human papillomavirus followed by specific polymerase chain reaction testing for 6, 11, 13, 16, 18, and 32 subtypes in order to confirm the clinical diagnosis. Finally, human papillomavirus-32-positive focal epithelial hyperplasia accompanying human papillomavirus-16-positive oral papilloma-like lesions were detected in different sites of the oral mucosa. Nucleotide sequence sequencing further confirmed the results. So in our clinical work, if the simultaneous occurrences of different human papillomavirus associated lesions are suspected, the multiple biopsies from different lesions and detection of human papillomavirus genotype are needed to confirm the diagnosis.

    Background The surgical management of breast intraductal papilloma without atypia (IDP) identified at core needle biopsy (CNB) is controversial. We assessed the rate of upgrade to carcinoma at surgical excision, and identified parameters predictive of upgrade. Methods We identified women with CNB diagnosis of intraductal papilloma without atypia or carcinoma at our center between 2003 and 2013. Radiologic-pathologic concordance was assessed for all cases, and discordant cases were excluded. We correlated the radiologic and clinicopathologic features of patients with CNB diagnosis of IDP with upgrade to carcinoma at surgical excision. Results Our study population consists of 189 women with 196 IDPs; 166 women (171 IDPs) underwent excision. The upgrade rate was 2.3% (4/171). The upgrade lesions were 2 invasive lobular carcinomas and 2 cases of ductal carcinoma in situ (DCIS). One case of DCIS involved the residual IDP, whereas the other 3 carcinomas were ≥8 mm away. Twenty-four women (25 IDPs) did not undergo excision, and had stable imaging at follow-up (median of 23.5 months). Conclusions The upgrade rate at excision of IDP diagnosed at CNB with radiologic-pathologic concordance is 2.3%. Our findings suggest that observation is appropriate for patients with radiologic-pathologic concordant CNB yielding IDP, regardless of its size. PMID:27315013

    Full Text Available Our previous studies indicated that JWA plays an important role in DNA damage repair, cell migration, and regulation of MAPKs. In this study, we investigated the role of JWA in chemical carcinogenesis using conditional JWA knockout (JWA(Δ2/Δ2 mice and two-stage model of skin carcinogenesis. Our results indicated that JWA(Δ2/Δ2 mice were resistant to the development of skin papillomas initiated by 7, 12-dimethylbenz(aanthracene (DMBA followed by promotion with 12-O-tetradecanoylphorbol-13-acetate (TPA. In JWA(Δ2/Δ2 mice, the induction of papilloma was delayed, and the tumor number and size were reduced. In primary keratinocytes from JWA(Δ2/Δ2 mice, DMBA exposure induced more intensive DNA damage, while TPA-promoted cell proliferation was reduced. The further mechanistic studies showed that JWA deficiency blocked TPA-induced activation of MAPKs and its downstream transcription factor Elk1 both in vitro and in vivo. JWA(Δ2/Δ2 mice are resistance to tumorigenesis induced by DMBA/TPA probably through inhibition of transcription factor Elk1 via MAPKs. These results highlight the importance of JWA in skin homeostasis and in the process of skin tumor development.

    Recurrent respiratory papillomatosis (RRP) is a viral induced disease, associated with exophytic epithelial lesions affecting the upper airways. Problem of treatment is the high recurrence of papilloma growth after surgical removal; therefore adjuvant therapy schemes have been established. Cidofovir was one of the agents used off-label in adjuvant therapy in the last years. However, there is ongoing discussion about the effectiveness and possible side effects. Aim of our study was to share our experience in treatment of RRP with cidofovir during the last 11 years. We analyzed all the data of patients treated for RRP at the Department for Phoniatrics of the Medical University of Graz between 1999 and 2011. 25 out of the 34 treated patients are at the moment under complete remission, in six patients partial remission could be achieved and two patients showed poor response to therapy, therefore the treatment with cidofovir was stopped. 21 patients received one cycle of monthly cidofovir, 11 patients received two and one patient three cycles of therapy. Number of procedures reached from one to six during each cycle. Average cumulative dose of one cycle was 79.7 mg (15-277.5 mg), in one patient 435 mg were used. One patient developed temporary, borderline neutropenia without symptoms. Despite the retrospective approach of this study with the limitation of several incomplete records, our results show promising long-term effects of adjuvant use of cidofovir. During this period, we did not observe any relevant side effects.

    The DNA of virus of human papilloma of high carcinogenic risk was detected in 116 cervical samples. At that, the morphological symptoms of background processes are detected in 19 samples, CIN 1 in 9, CIN 2 in 23, CIN 3 in 54 (and out of them carcinoma in situ in 13), epidermoid cancer (squamous cell carcinoma) in 11 cases. The viral load of human papilloma of high carcinogenic risk in all samples of DNA exceeded threshold of clinical value (3 lg copies of DNA of human papilloma/105 cells). The genetic typing of human papilloma of high carcinogenic risk revealed the dominance of human papilloma of type 16 in 49.7%, type 33 in 15.3%, type 31 in 12.3% and type 45 in 5.5%. In women with background processes in cervix of the uterus DNA of human papilloma type 16 was detected more often in episome form. In case of dysplastic alterations of epithelium and cervical cancer DNA of human papilloma type 16 is detected in mixt form with different degree of integration into cell genome.

    Objective To detect expressions of G3BP and Stathmin in Sinonasal inverted papilloma( NIP) and explore their roles in the development of NIP as well as their interrelationships. Method The immunohistochemical (PV-9000 two-step method) method was used to analyze protein expressions of G3BP and Stathmin in paraffin embedded tissues from 34 cases of sinonasal inverted papilloma, At the same time, expressions of these two proteins was also measured in 20 cases of inferior nasal concha mucosa and 12 cases of nasal squamous cell carcinoma as controls. SPSS13.0 was applied to determine the differences and correlation in the NIP. Results Positive expression rates of Stathmin protein and G3BP protein in sinonasal inverted papilloma were 52.9% and 73.5% , which were significantly higher than those in the inferior nasal concha mucosa ( 0% and 0% ;P 0.05). Stathmin was positively related to expression of G3BP( r, > 0, P < 0. 001). Conclusion Stathmin protein and G3BP protein were highly expressed in sinonasal inverted papilloma. The result indicates that they may be associated with the recur-rence and invasiveness of sinonasal inverted papilloma. Because Stathmin was positively related to expression of G3BP, joint detection of Stathmin and G3BP may be useful in the diagnosis and prognosis of cancer.%目的 检测Stathmin、G3BP蛋白在鼻腔、鼻窦内翻性乳头状瘤(NIP)、下鼻甲黏膜(INCM)及鼻鳞状细胞癌(NSCC)中的表达情况,及其在NIP中可能的作用及相互关系.方法 采用免疫组织化学法(PV-9000二步法)检测G3BP及Stathmin蛋白在34例NIP病理标本蜡块切片中的表达情况,并同时检测20例下鼻甲黏膜以及12例鼻鳞状细胞癌组织标本蜡块切片中两蛋白的表达作为对照,运用SPSS 13.0软件进行统计学分析,观察两指标在不同组织中的表达情况,分析其在NIP中的表达有无相关性.结果 按本实验所采用计数标准,Stathmin、G3BP 蛋白在NIP组织中

  15. Beta-catenin accelerates human papilloma virus type-16 mediated cervical carcinogenesis in transgenic mice.

    Full Text Available Human papilloma virus (HPV is the principal etiological agent of cervical cancer in women, and its DNA is present in virtually all of these tumors. However, exposure to the high-risk HPV types alone is insufficient for tumor development. Identifying specific collaborating factors that will lead to cervical cancer remains an unanswered question, especially because millions of women are exposed to HPV. Our earlier work using an in vitro model indicated that activation of the canonical Wnt pathway in HPV-positive epithelial cells was sufficient to induce anchorage independent growth. We therefore hypothesized that constitutive activation of this pathway might function as the "second hit." To address this possibility, we developed two double-transgenic (DT mouse models, K14-E7/ΔN87βcat and K14-HPV16/ΔN87βcat that express either the proteins encoded by the E7 oncogene or the HPV16 early region along with constitutively active β-catenin, which was expressed by linking it to the keratin-14 (K14 promoter. We initiated tumor formation by treating all groups with estrogen for six months. Invasive cervical cancer was observed in 11% of the K14-ΔN87βcat mice, expressing activated β-catenin and in 50% of the animals expressing the HPV16 E7 oncogene. In double-transgenic mice, coexpression of β-catenin and HPV16 E7 induced invasive cervical cancer at about 7 months in 94% of the cases. We did not observe cervical cancer in any group unless the mice were treated with estrogen. In the second model, K14-HPV16 mice suffered cervical dysplasias, but this phenotype was not augmented in HPV16/ΔN87βcat mice. In summary, the phenotypes of the K14-E7/ΔN87βcat mice support the hypothesis that activation of the Wnt/β-catenin pathway in HPV-associated premalignant lesions plays a functional role in accelerating cervical carcinogenesis.

    Full Text Available Background. A persistent infection with high-risk genotypes of human papilloma viruses (HPV represents the most important etiologic factor for the development of cervical cancer, the second most frequent cancer in women in Slovenia as well as elsewhere in the world. In the detection of precancerous lesions the cervical Papanicolaou (Pap smear screening is used in Slovenia and worldwide. Management of patients with repeat abnormal smears (Pap II represents a great and complex clinical and public health problem; repeat cytologic examinations are the routine procedure in many countries, also in Slovenia, although the sensitivity of Pap smear testing in the detection of cervical intraepithelial neoplasms (CIN II and III is relatively low. In cases of abnormal squamous cells and mildly dyskaryotic cells the presence of infections with high-risk HPV genotypes is being increasingly used as a complementary method to Pap smear testing.Methods and patients. In the study we enrolled 148 women who within two years had three subsequent Pap II smears (abnormal squamous cells or mildly dyskaryotic cells. The prevalence of HPV infections was determined using three molecular tests: Hybrid Capture II (HCII (Digene Corporation, Gaithersburg, USA and two variants of polymerase chain reaction (PCR-PGMY11/PGMY09 and PCR-CPI/CPIIG. HPV genotypes were determined using the method of enzyme restriction of PCR products multiplied by group-specific oligonucleotid primers PGMY11/PGMY09.Results. HPV infection was detected in 25.7% of women. In women aged ≤ 30 years a statistically significantly higher incidence of HPV infections was found (37.8% than in women aged ≥ 30 years (20.4%. In women aged ≤ 30 years most frequent infections, and also equally distributed, were the ones with high-risk genotypes HPV 16 and HPV 73 and with a potentially high-risk genotype HPV 26. In women aged ≥ 30 years most frequent infections, and also equally distributed, were the ones with

    We previously demonstrated in a cottontail rabbit papillomavirus (CRPV) challenge model that recombinant Bacille Calmette-Guerin (rBCG) could potentially be used as a prophylactic vaccine vehicle to deliver papillomavirus proteins. In this study we investigated whether regression of CRPV-induced papillomas could be achieved following immunisation of out-bred New Zealand White rabbits with rBCG expressing CRPVL2, CRPVE2, CRPVE7 or CRPVL2E7E2 proteins. Rabbits immunised with rBCG/CRPVL2E7E2 had papillomas that were largely suppressed and were significantly smaller compared to the rBCG negative control group (Prabbits immunised with rBCG/CRPVL2E7E2 had papillomas that completely regressed 1.5 weeks post third immunisation. Rabbits immunised with rBCG/CRPVL2, rBCG/CRPVE7, or rBCG/CRPVE2 had papillomas that were significantly smaller than the negative control rabbits (P

    The occurrence and localization of vegetative viral DNA replication was studied in sections of tumors induced by the rabbit Shope papilloma virus, in cottontail and domestic rabbit papillomas, in primary domestic rabbit carcinoma, and in transplantable VX2 carcinoma, by in situ hybridization of radioactive RNA complementary to viral DNA. Vegetative viral DNA replication and viral protein synthesis were compared by means of cytological hybridization and immunofluorescence techniques on adjacent frozen sections. Vegetative viral DNA replication is completely repressed in the proliferating cellular layers of these tumors, which suggests a provirus state of the viral genome, as in other cells transformed by oncogenic DNA viruses. Vegetative viral DNA replication is induced, after initiation of the keratinization, in cells of cottonail rabbit papillomas, where it is usually followed by viral protein synthesis; this illustrates the influence of the physiological state of the host cell on the control of viral functions. Vegetative viral DNA replication is deteced only in a few cells of domestic rabbit papillomas, at the end of the keratinization process; this observation provides indirect evidence that the DNA synthesis specifically induced in these tumors after the onset of keratinization reflects mostly the induction of cellular DNA synthesis.

    The aim of this paper is to give a detailed description of the so-called "chronic recurrent multifocal osteomyelitis" (CRMO). The clinical, radiological and histopathological results of an analysis of 29 cases (15 children/adolescents and 14 adults) are presented and correlated to current data from the literature. We could delinate the following points: 1. CRMO is a systemic aseptic inflammation of the bone marrow (Osteitis), it can occur polytopically and association with pustulous dermatologic symptoms is possible. 2. It is not a rare disease 3. Osteomyelitis is probably "reactive" and a plasma-cell sclerotic process with ist own characteristic histologic three-phase course. 4. We could observe 5 specific types of localization which can be documented by X-ray or bone scan. 5. Accompanying arthritis os often present, especially "sympathetic coxitis". 6. The use of drugs in treatment of CRMO (i.e. azithromycin, calcitonin, and bisphosphonates) is discussed. In conclusion we want to point out, that 1. 99mTC bone scan should always be performed when there is suspicion for CRMO to reveal the pattern of affection, 2. the rheumatologist and dermatologist should be contacted, 3. operation is normally not necessary for treatment of the mostly self-limitin disease, and 4. the term "SAPHO syndrome" should be avoided, further differentiation of the diagnosis is necessary.

    Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory bone disease occurring primarily in children and adolescents. Episodes of systemic inflammation occur due to immune dysregulation without autoantibodies, pathogens or antigen-specific T cells. CRMO is characterised by the insidious onset of pain with swelling and tenderness over the affected bones. Clavicular involvement was the classical description; however, the metaphyses and epiphyses of long bones are frequently affected. Lesions may occur in any bone, including vertebrae. Characteristic imaging includes bone oedema, lytic areas, periosteal reaction and soft tissue reaction. Biopsies from affected areas display polymorphonuclear leucocytes with osteoclasts and necrosis in the early stages. Subsequently, lymphocytes and plasma cells predominate followed by fibrosis and signs of reactive new bone forming around the inflammation. Diagnosis is facilitated by the use of STIR MRI scanning, potentially obviating the need for biopsy and unnecessary long-term antibiotics due to incorrect diagnosis. Treatment options include non-steroidal anti-inflammatory drugs and bisphosphonates. Biologics have been tried in resistant cases with promising initial results. Gene identification has not proved easy although research in this area continues. Early descriptions of the disease suggested a benign course; however, longer-term follow up shows that it can cause significant morbidity and longer-term disability. Although it has always been thought of as very rare, the prevalence is likely to be vastly underestimated due to poor recognition of the disease.

  5. Recurrent neural collective classification.

    2013-12-01

    With the recent surge in availability of data sets containing not only individual attributes but also relationships, classification techniques that take advantage of predictive relationship information have gained in popularity. The most popular existing collective classification techniques have a number of limitations-some of them generate arbitrary and potentially lossy summaries of the relationship data, whereas others ignore directionality and strength of relationships. Popular existing techniques make use of only direct neighbor relationships when classifying a given entity, ignoring potentially useful information contained in expanded neighborhoods of radius greater than one. We present a new technique that we call recurrent neural collective classification (RNCC), which avoids arbitrary summarization, uses information about relationship directionality and strength, and through recursive encoding, learns to leverage larger relational neighborhoods around each entity. Experiments with synthetic data sets show that RNCC can make effective use of relationship data for both direct and expanded neighborhoods. Further experiments demonstrate that our technique outperforms previously published results of several collective classification methods on a number of real-world data sets.

    The reported positions of 964 suspected nova eruptions in M31 recorded through the end of calendar year 2013 have been compared in order to identify recurrent nova candidates. To pass the initial screen and qualify as a recurrent nova candidate two or more eruptions were required to be coincident within 0.1', although this criterion was relaxed to 0.15' for novae discovered on early photographic patrols. A total of 118 eruptions from 51 potential recurrent nova systems satisfied the screening criterion. To determine what fraction of these novae are indeed recurrent the original plates and published images of the relevant eruptions have been carefully compared. This procedure has resulted in the elimination of 27 of the 51 progenitor candidates (61 eruptions) from further consideration as recurrent novae, with another 8 systems (17 eruptions) deemed unlikely to be recurrent. Of the remaining 16 systems, 12 candidates (32 eruptions) were judged to be recurrent novae, with an additional 4 systems (8 eruptions) b...

    Vulvovaginitis is the most common gynecologic condition seen by practitioners rendering primary care to women. Vulvovaginitis Candidiasis (VVC) is the most common type of vaginitis and this study aimed at specifying VVC recurrence during pregnancy. In this prospective study, 150 pregnant women suffering from vaginal excretion, morsus and itching were studied. Initially, the patients were treated using clotrimazole local cream (5 g) for 7 successive days. After initial treatment, the patients were freely visited once a month until delivery considering vaginitis symptoms and VVC recurrence was examined during pregnancy. Mean age of the understudy mothers was 27.26 +/- 3.76. Mean of recurrence number was 0.17 +/- 0.48 during the first trimester. Mean of recurrence number was 0.92 +/- 0.76 during the second trimester. Mean of recurrence number was 2.16 +/- 0.63 during the third trimester. Statistically significant difference was between recurrences during three trimesters of pregnancy (p < 0.001). There is statistically significant difference between mean number of recurrences during three trimesters of pregnancy.

Medline search via PubMed was performed with the keywords imaging, recurrent, and prostate cancer as well as more detailed searches including the keywords bone scan, bone scintigraphy, computed tomography, magnetic resonance imaging, positron emission tomography, PET, choline, FDG, prostate-specific membrane antigen, and PSMA, with emphasis on recent literature from 2010 to the present. Non-English published literature was excluded. Abstracts and full-text articles were reviewed and assessed for relevant content. In diagnostic imaging and particularly with newer technologies like positron emission tomography (PET), a profound lack of prospectively designed studies in recurrent PCa has to be noted. In most studies histologic validation has only been performed in a subset of patient cohorts. Heterogeneity of included patient cohorts, lack of standardized assessment, as well as diverging end points, hamper systematic comparison of different image modalities. Thus evidence for currently used imaging in recurrent PCa is only presented descriptively. Computed tomography and magnetic resonance imaging (MRI) as well as bone scintigraphy still represent the standard imaging for recurrent PCa; however, particularly for detection of local recurrence, multiparametric MRI is a valuable imaging modality. PET using choline and particularly tracers against prostate-specific membrane antigen might improve visualization of metastatic lesions. These findings need to be validated in prospective trials. Imaging of recurrent prostate cancer (PCa) is important to guide further treatment. Computed tomography, magnetic resonance imaging, and bone scintigraphy represent the current standard.

    2010-09-01

    Full Text Available Recent results about spike-timing-dependent plasticity (STDP in recurrently connected neurons are reviewed, with a focus on the relationship between the weight dynamics and the emergence of network structure. In particular, the evolution of synaptic weights in the two cases of incoming connections for a single neuron and recurrent connections are compared and contrasted. A theoretical framework is used that is based upon Poisson neurons with a temporally inhomogeneous firing rate and the asymptotic distribution of weights generated by the learning dynamics. Different network configurations examined in recent studies are discussed and an overview of the current understanding of STDP in recurrently connected neuronal networks is presented.

    Abstract Recurrent wheezing (RW) has a significant impact on infants, caregivers, and society, but morbidity and related medical resource utilization (MRU) have not been thoroughly explored. The burden of RW needs to be documented with population-based data. The objective was to assess the characteristics, medical management, and MRU of RW infants identified from national claims data. Infants aged from 6 to 24 months, receiving ≥2 dispensations of respiratory drugs within 3 months, and presenting a marker of poor control (index date), were selected. During the 6 months after index date, MRU was described in the cohort and among 3 subgroups with more severe RW, defined as ≥4 dispensations of respiratory drugs, ≥3 dispensations of oral corticosteroids (OCS), or ≥1 hospitalization for respiratory symptoms. A total of 115,489 infants had RW, corresponding to 8.2% of subjects in this age group. During follow-up, 68.7% of infants received inhaled corticosteroids, but only 1.8 U (unit) were dispensed over 6 months, suggesting discontinuous use. Control was mostly inadequate: 61.7% of subjects received OCS, 80.2% antibiotics, and 71.2% short-acting beta-agonists, and medical/paramedical visits were numerous, particularly for physiotherapy. Severe RW concerned 39.0% of the cohort; 32.8% and 11.7% of infants had repeated use of respiratory drugs and OCS, respectively, and 5.5% were hospitalized for respiratory symptoms. In this real-life nation-wide study, RW was common and infants had poor control and high MRU. Interventions are needed to support adequate use of controller therapy, and to improve medical care.

    This paper is a first step in the study of the recurrence behavior in random dynamical systems and randomly perturbed dynamical systems. In particular we define a concept of quenched and annealed return times for systems generated by the composition of random maps. We moreover prove that for super-polynomially mixing systems, the random recurrence rate is equal to the local dimension of the stationary measure.

    Despite improvements in diagnostic techniques and progress made in mapping genes associated with syndromal mental handicap, the estimation of recurrence risks in non-syndromal mental retardation is still dependent on empirical data. Unfortunately, few studies are available to guide the clinician and their results differ significantly. For example, recurrence risks to all sibs of a male index patient with severe mental retardation vary between 3.5% and 14% in commonly quoted series. The presen...

    Sixteen out of 720 patients with carpal tunnel syndrome who had undergone surgery since 1979 were reoperated for a "recurrence" (2.2%). Twelve of these patients had been originally operated on in our department. Thus, our own recurrence rate is 1.7%. Three patients deteriorated following surgery, 6 had an unsatisfactory improvement, and in 7 the symptoms recurred after initial improvement. Eight of the reoperated patients had a predisposing disease (terminal renal insufficiency, insulin-dependent diabetes mellitus, acromegaly). In 10 of the 16 cases the initial operation had been carried out by surgeons in the first three years of training. Reoperation revealed incomplete splitting of the transverse carpal ligament in 10 cases, compression of the median nerve by the scar in 4, injury of the muscular branch in 1, and an anatomical variant as cause of incomplete decompression in 1 patient. "Recurrences" after carpal tunnel surgery are predominantly due to inadequacies of the first procedure. A remarkable number of patients (50%) has predisposing diseases. Interfascicular or epineural neurolysis and complete exposure and neurolysis of the median nerve and its branches is necessary only in cases of recurrence. Their omission at the first surgery does not result in an increased recurrence rate. Our observations indicate that the number of operations for recurrent carpal tunnel syndrome can probably be reduced when the first operation is performed with care and experience. Patients with carpal tunnel syndrome secondary to a systemic disease are particularly at risk.

    Full Text Available Background: Cervical cancer is a major health problem globally, especially in sub-Saharan Africa, Nigeria inclusive. One of the preventive measures is the vaccination of teenagers against oncogenic human papilloma virus. The aim of this study was to find out the level of knowledge mothers possess about these vaccines and their willingness to administer vaccination to their teenage girls. Materials and Methods: This was a cross-sectional descriptive study of 255 consecutive women attending antenatal clinic at the University of Abuja Teaching Hospital, Abuja. They were given either a self-administered questionnaire or interviewer-administered questionnaire containing both closed and open-ended questions. Information recorded includes socio-demographic variables, knowledge of cervical cancer, knowledge of HPV/HPV vaccines and acceptance of these vaccines for their adolescent girls. The data was analysed using descriptive statistics. Results: The mean age of the respondents was 26.9 years. Over 90% had at least secondary education. A total of 102 (40% had the knowledge of cancer of the cervix while 153 (60% had never heard about it. Overall, 236 (92.5% of them had no idea about the predisposing factors. The study showed that only 23 (9.0% out of the total respondents had heard about human papilloma virus (HPV infection. In the same vein, 20 (7.8% had knowledge about HPV vaccine. Among the respondents, who had the knowledge of HPV and vaccination, 18.2% and 23.4% of them had secondary and tertiary levels of education respectively. Overall, 160 (62.8% accepted that the vaccines could be administered to their teenage girls. Conclusions: Awareness of cervical cancer, HPV infections, and HPV vaccines is low among antenatal clinic attendees in Gwagwalada, Abuja. However, majority of them would want their girls vaccinated against HPV infections. There is a need for all stakeholders to step up awareness creation for improved HPV vaccination project in

    Prostaglandin E(2) (PGE(2)) is elevated in many tumor types, but PGE(2)'s contributions to tumor growth are largely unknown. To investigate PGE(2)'s roles, the contributions of one of its receptors, EP2, were studied using the mouse skin initiation/promotion model. Initial studies indicated that protein kinase A (PKA), epidermal growth factor receptor (EGFR) and several effectors-cyclic adenosine 3',5'-monophosphate response element-binding protein (CREB), H-Ras, Src, protein kinase B (AKT) and extracellular signal-regulated kinase (ERK)1/2-were activated in 12-O-tetradecanoylphorbol-13-acetate (TPA)-promoted papillomas and that PKA and EGFR inhibition (H89 and AG1478, respectively) decreased papilloma formation. EP2's contributions to the activation of these pathways and papilloma development were determined by inhibiting endogenous TPA-induced PGE(2) production with indomethacin (Indo) and concomitantly treating with the EP2 agonist, CAY10399 (CAY). CAY treatment restored papilloma formation in TPA/Indo-treated mice and increased cyclic adenosine 3',5'-monophosphate and PKA activation as measured by p-CREB formation. CAY treatment also increased EGFR and Src activation and their inhibition by AG1478 and PP2 indicated that Src was upstream of EGFR. CAY also increased H-Ras, ERK1/2 and AKT activation, and AG1478 decreased their activation indicating EGFR being upstream. Supporting EP2's contribution, EP2-/- mice exhibited 65% fewer papillomas and reduced Src, EGFR, H-Ras, AKT and ERK1/2 activation. G protein-coupled receptor (GPCR) activation of EGFR has been reported to involve Src's activation via a GPCR-beta-arrestin-Src complex. Indeed, immunoprecipitation of beta-arrestin1 or p-Src indicated the presence of an EP2-beta-arrestin1-p-Src complex in papillomas. The data indicated that EP2 contributed to tumor formation via activation of PKA and EGFR and that EP2 formed a complex with beta-arrestin1 and Src that contributed to signaling and/or EP2 desensitization.

  6. An Undecidable Nested Recurrence Relation

    CERN Document Server

    Celaya, Marcel

    2012-01-01

    Roughly speaking, a recurrence relation is nested if it contains a subexpression of the form ... A(...A(...)...). Many nested recurrence relations occur in the literature, and determining their behavior seems to be quite difficult and highly dependent on their initial conditions. A nested recurrence relation A(n) is said to be undecidable if the following problem is undecidable: given a finite set of initial conditions for A(n), is the recurrence relation calculable? Here calculable means that for every n >= 0, either A(n) is an initial condition or the calculation of A(n) involves only invocations of A on arguments in {0,1,...,n-1}. We show that the recurrence relation A(n) = A(n-4-A(A(n-4)))+4A(A(n-4)) +A(2A(n-4-A(n-2))+A(n-2)). is undecidable by showing how it can be used, together with carefully chosen initial conditions, to simulate Post 2-tag systems, a known Turing complete problem.

    The reported positions of 964 suspected nova eruptions in M31 recorded through the end of calendar year 2013 have been compared in order to identify recurrent nova (RN) candidates. To pass the initial screen and qualify as a RN candidate, two or more eruptions were required to be coincident within 0.′1, although this criterion was relaxed to 0.′15 for novae discovered on early photographic patrols. A total of 118 eruptions from 51 potential RN systems satisfied the screening criterion. To determine what fraction of these novae are indeed recurrent, the original plates and published images of the relevant eruptions have been carefully compared. This procedure has resulted in the elimination of 27 of the 51 progenitor candidates (61 eruptions) from further consideration as RNe, with another 8 systems (17 eruptions) deemed unlikely to be recurrent. Of the remaining 16 systems, 12 candidates (32 eruptions) were judged to be RNe, with an additional 4 systems (8 eruptions) being possibly recurrent. It is estimated that ∼4% of the nova eruptions seen in M31 over the past century are associated with RNe. A Monte Carlo analysis shows that the discovery efficiency for RNe may be as low as 10% that for novae in general, suggesting that as many as one in three nova eruptions observed in M31 arise from progenitor systems having recurrence times ≲100 yr. For plausible system parameters, it appears unlikely that RNe can provide a significant channel for the production of Type Ia supernovae.

  8. Recurrence Statistics of Great Earthquakes

    2013-01-01

    We investigate the sequence of great earthquakes over the past century. To examine whether the earthquake record includes temporal clustering, we identify aftershocks and remove those from the record. We focus on the recurrence time, defined as the time between two consecutive earthquakes. We study the variance in the recurrence time and the maximal recurrence time. Using these quantities, we compare the earthquake record with sequences of random events, generated by numerical simulations, while systematically varying the minimal earthquake magnitude Mmin. Our analysis shows that the earthquake record is consistent with a random process for magnitude thresholds 7.0<=Mmin<=8.3, where the number of events is larger. Interestingly, the earthquake record deviates from a random process at magnitude threshold 8.4<=Mmin<= 8.5, where the number of events is smaller; however, this deviation is not strong enough to conclude that great earthquakes are clustered. Overall, the findings are robust both qualitat...

    Thirty patients with recurrent primary nasopharyngeal carcinoma were reirradiated between 1949 and 1976. Twenty eventually demonstrated recurrence at or near the primary site, involving the nasopharynx in 4 and the central nervous system in 16. Long-term palliation was often achieved, and there were no severe complications except for one patient who died of necrosis of the base of the skull. The most frequent problems were hearing loss and trismus; necrosis of the nasopharynx was seen in only 2 patients. With therapy in the range of 18-25 MeV, significant palliation and an occational cure can be achieved without excessive risk. Recurrent disease involving the skull may be controlled for several years using current techniques.

    Recurrence of quantum walks on lattices can be characterized by the generalized Polya number. Its value reflects the difference between a classical and a quantum system. The dimension of the lattice is not a unique parameter in the quantum case; both the coin operator and the initial quantum state of the coin influence the recurrence in a nontrivial way. In addition, the definition of the Polya number involves measurement of the system. Depending on how measurement is included in the definition, the recurrence properties vary. We show that in the limiting case of frequent, strong measurements, one can approach the classical dynamics. Comparing various cases, we have found numerical indication that our previous definition of the Polya number provides an upper limit.

  11. Recurrent Novae — A Review

    Directory of Open Access Journals (Sweden)

    K. Mukai

    2015-02-01

    Full Text Available In recent years, recurrent nova eruptions are often observed very intensely in wide range of wavelengths from radio to optical to X-rays. Here I present selected highlights from recent multi-wavelength observations. The enigma of T Pyx is at the heart of this paper. While our current understanding of CV and symbiotic star evolution can explain why certain subset of recurrent novae have high accretion rate, that of T Pyx must be greatly elevated compared to the evolutionary mean. At the same time, we have extensive data to be able to estimate how the nova envelope was ejected in T Pyx, and it turns to be a rather complex tale. One suspects that envelope ejection in recurrent and classical novae in general is more complicated than the textbook descriptions. At the end of the review, I will speculate that these two may be connected.

    2002-01-01

    We have observed elevated NF-κB DNA-binding activity in nuclear extracts from human papillomavirus type 6- and 11-infected laryngeal papilloma tissues. The predominant DNA-binding species is the p50/p50 homodimer. The elevated NF-κB activity could be correlated with a reduced level of cytoplasmic IκBβ and could be associated with the overexpression of p21CIP1/WAF1 in papilloma cells. Increased NF-κB activity and cytoplasmic accumulation of p21CIP1/WAF1 might counteract death-promoting effects elicited by overexpressed PTEN and reduced activation of Akt and STAT3 previously noted in these tissues.

    1,122 uterine cancer patients above FIGO stage I a were treated at our hospital in the decade from 1980 to 1989. Total 69 patients diagnosed as recurrent cervical cancer had 82 lesions in 11 sites. The most frequent recurrent sites were uterus, vaginal stump and vaginal wall; the second sites were parametrium and pelvic wall. Radiotherapy and hyperthermia were done to patients with these lesions. Chemotherapy and radiotherapy were used to patients with distant metastatic lesions to left supraclavicular lymph nodes and lung. But there has been no good results.

    Galactosemia is a treatable metabolic disorder caused by the deficiency of enzyme galactose-1-phosphate uridyl transferase (GALT) and inherited as an autosomal recessive trait. A case of neonate manifesting with recurrent Escherichia coli sepsis is presented here which turned out to be a classic galactosemia. No other common presenting features were observed in this infant except cataract on slit lamp examination. To the best of our knowledge, there is no case of galactosemia reported in literature which presented with recurrent neonatal sepsis without hepatomegaly, hyperbilirubinemia, bleeding disorder, vomiting, diarrhea, failure to thrive, hypoglycemia, coagulopathy, hemolysis or renal tubular acidosis.

    To evaluate whether biopsy with vacuum-assisted biopsy (VAB) devices improves histologic underestimation rates of benign papillomas when compared to smaller bore core needle biopsy (CNB) devices. Patients with biopsy-proven benign papillomas with surgical resection or minimum 12 months follow-up were selected. Two breast pathologists reviewed all pathology slides of percutaneous and excisional biopsy specimens. Histologic underestimation rates for lesions biopsied with 10-12 Gauge (G) VAB were compared to those with 14G CNB. A total of 107 benign papillomas in 107 patients from two centers were included. There were 60 patients (mean age 57 years, SD 10.3 years) diagnosed with VAB and 47 patients (mean age 57.6 years, SD 11.3 years) with 14G CNB who underwent surgical excision or imaging follow-up. The upgrade rate to ductal carcinoma in situ or invasive carcinoma was 1.6% (1/60) with VAB and 8.5% (4/47) with 14G. Upgrade to atypia was 3.3% (2/60) after VAB and 10.6% (5/47) with CNB. The total underestimation rates were 5% (3/60) with VAB and 19.1% (9/47) with CNB. The odds of an upgrade to malignancy was 5.5 times higher with a 14G needle than VAB (95% CI: 0.592-50.853, p = 0.17). We observed a lower but not statistically significant upgrade rate to malignancy and atypia with the use of the 10-12 G VAB as compared with 14G CNB. When a papilloma without atypia is diagnosed with vacuum biopsy there is a high likelihood that it is benign; however, if surgical excision is not performed, long-term follow-up is still required. © 2016 Wiley Periodicals, Inc.

    Chimera states, characterised by coexistence of coherence and incoherence in coupled dynamical systems, have been found in various physical systems, such as mechanical oscillator networks and Josephson-junction arrays. We used recurrence plots to provide graphical representations of recurrent patterns and identify chimera states. Moreover, we show that recurrence plots can be used as a diagnostic of chimera states and also to identify the chimera collapse. - Highlights: • Chimera states have been found in various physical systems. • Recurrence plots is a graphical method useful to locate recurring patterns. • We used recurrence plots to identify the chimera states. • We show also the recurrence plots can identify the chimera collapse.

    2001-01-01

    The pigmented vilionodular synovitis (PVNS) is a tumour like disease of unknown origin that often shows recurrence. The pathogenesis is still unknown and therefore the question of the right therapy is not resolved. With a case report of a patient with recurrence after two arthroscopic synovectomies, PVNS is discussed against the background of the clinical, histological, and radiological features. We performed an open synovectomy and cystic lesions in both condyles of the femur and proximal tibia were filled with homologous and autologous cancellous bone. Three months later the patient had no pain and the bone density in the former cystic lesions was appropriate. The pathogenesis is still unknown. Diagnosis often is obtained much too late due to missing specific symptoms. PVNS occurs in local forms as well as in a diffuse growth pattern. Recurrence rates of up to 78% are very high. Besides arthroscopic and open synovectomy, the treatment with radiosynoviorthesis must be considered. Depending on the growth pattern, the tumour masses, and the affected joint, the therapy has to be chosen very carefully and sometimes different forms have to be combined if a recurrence--free result is to be achieved.

    We derive recurrence relations between phase space expressions in different dimensions by confining some of the coordinates to tori or spheres of radius $R$ and taking the limit as $R \\to \\infty$. These relations take the form of mass integrals, associated with extraneous momenta (relative to the lower dimension), and produce the result in the higher dimension.

    Sixty-eight hospital-admitted patients with a first episode of Clostridium difficile infection (CDI) were included and followed up during 1 year. Faeces samples were collected at 1, 2, 6 and 12 months after inclusion and analyzed for the presence of C. difficile toxin B, genes for toxin A, toxin B, binary toxin and TcdC deletion by PCR. All strains were also PCR-ribotyped and the MICs of the isolates were determined against eight antimicrobial agents. In 68 patients initially included, antibiotics, clinical signs and co-morbidities were analyzed and 56 were evaluable for recurrences. The mean number of different antibiotics given during 3 months prior to inclusion was 2.6 (range 0-6). Six patients had not received any antibiotics and three of them had diagnosed inflammatory bowel disease. Thirty-two patients (57%) had either a microbiological or clinical recurrence, 16 of whom had clinical recurrences that were confirmed microbiologically (13, 23%) or unconfirmed by culture (3, 5%). Twenty-nine patients were positive in at least one of the follow-up tests, 16 had the same ribotype in follow-up tests, i.e. relapse, and 13 a different ribotype, i.e., reinfection. Most common ribotypes were 078/126, 020, 023, 026, 014/077, 001 and 005. No strain of ribotype 027 was found. Strains ribotype 078/126 and 023 were positive for binary toxin and were the strains most prone to cause recurrence. All strains were sensitive to vancomycin and metronidazole. Patients with recurrences were significantly older (p = 0.02) and all patients had a high burden of comorbidities, which could explain the high fatality rate, 26 (38%) patients died during the 1-year follow-up.

    Recurrent periductal mastitis is a benign breast disorder that often features a mammary fistula that runs between periareolar skin and the ductal mammary system. Due to the high recurrence rate of this disease, its management is controversial. This study was designed to assess the efficacy of fistulectomy (Hadfield operation), particularly with regard to its long-term outcome. We reviewed all women with recurrent periductal mastitis who underwent the Hadfield operation in the Breast Center in S.Orsola-Malpighi Hospital (Bologna University) from 2005 to 2015. All but one of the patients were heavy smokers and presented with a recurrent periareolar abscess and a periareolar mammary fistula. Eighteen women underwent the Hadfield surgical treatment. Mean age at the time of presentation was 42 years; 17 of 18 women smoked >10 cigarettes/d. All patients had a breast ultrasonography or mammography. Half of the patients had undergone antibiotic therapy with one or more prior abscess drainages or another form of operative treatment. All patients who underwent operative treatment had no postoperative events and were satisfied with the cosmetic results. Squamous metaplasia was always present in the specimens. After a median follow-up of 36 months, 2 patients developed a recurrence after a few months; neither had stopped smoking. Based on our review of the literature and taking into account the results of this study, it seems clear that the best treatment involves a combined total excision of the affected duct and the fistulous tract. Due to the important role of smoking in this disease, it is important to encourage patients to stop smoking. Copyright © 2016 Elsevier Inc. All rights reserved.

    1994-04-01

    Spontaneous pneumothorax (PNO) is usually due to rupture of a small subpleural bleb into the pleural cavity and affects mainly young men. After simple drainage, recurrence occurs in about 50% of cases. The risk of recurrence increases after each new PNO. Secondary PNO complicates an underlying pulmonary disease, especially chronic obstructive pulmonary disease with emphysema. A new form of secondary PNO has emerged in the recent years in AIDS patients with pneumocystis carinii pneumonia. We have shifted to a thoracoscopic therapy of PNO since May 1991. 25 PNO in 24 patients (1 bilateral) have been treated since that time up to April 1993. 19 PNO were primary, whereas 6 were secondary, included 3 iatrogenic PNO. Resection of the leaking parenchymal area was performed in 20 patients, and parietal partial pleurectomy was done in 20 cases. In the remaining cases, fibrin glue was applied on the lesion and in 3 cases, chemical pleurodesis was attempted using silver nitrate or talc. 1 AIDS patient died of ARDS. 3 patients had recurrent PNO and had thoracotomy without complication. 21 patients did well. Partial PNO recurred in one of them 4 months later, and was treated by simple needle aspiration. Thoracoscopy is a useful method to treat recurrent or persistent spontaneous PNO. After only 25 cases, our success rate in primary PNO is 90%. There should be a learning curve. On the basis of our experience, we believe that recognition of the lesion and its resection as well as apical parietal pleurectomy are necessary to obtain good results and a low recurrence rate.

    Full Text Available Retroperitoneal liposarcoma presenting as an inguinal hernia is a rare entity. We present the first case of Giant recurrent liposarcoma presenting as a recurrent inguinal hernia in a 40-year-old male. Physical examination showed an irreducible lump in the right inguinal region and a scar in the right lumbar and right inguinal region. Computed tomography (CT scan of abdomen revealed it to be a retro peritoneal mass extending into the right inguinal region along and involving the cord structures. Wide local excision of the tumour with right orchidectomy and inguinal hernioplasty was performed. Histo-pathology confirmed it to be a liposarcoma. Patient received postoperative radio therapy. Follow up of two years has shown him to be disease free. Retroperitoneal liposarcoma can grow along cord structures into the inguinal canal and mimic an irreducible indirect inguinal hernia.

    This book features 13 papers presented at the Fifth International Symposium on Recurrence Plots, held August 2013 in Chicago, IL. It examines recent applications and developments in recurrence plots and recurrence quantifi cation analysis (RQA) with special emphasis on biological and cognitive systems and the analysis of coupled systems using cross-recurrence methods. Readers will discover new applications and insights into a range of systems provided by recurrence plot analysis and new theoretical and mathematical developments in recurrence plots. Recurrence plot based analysis is a powerful tool that operates on real-world complex systems that are nonlinear, non-stationary, noisy, of any statistical distribution, free of any particular model type, and not particularly long. Quantitative analyses promote the detection of system state changes, synchronized dynamical regimes, or classifi cation of system states.

    Our study explored whether the HPV status of tumors is associated with the outcome of radiotherapy in patients with cervical cancer. A total of 84 patients with cervical cancer (6 stage I, 10 stage II, 49 stage III, and 19 stage IV) who underwent definitive radiotherapy between January 1995 and June 2000 were included in this study. Tumor samples were obtained from all patients by punch biopsy prior to radiotherapy. The presence of HPV and its type were analyzed by PCR-based assay using the consensus primers for E6 and L1 regions. Actuarial methods were used to calculate overall survival, and disease-free survival. A total of 42 patients (50%) had cancer recurrence after radiotherapy. HPV-positive tumors were found in 76.2% (64 cases) of the patients. HPV-negative patients survived significantly shorter compared to the HPV-positive patients in the overall survival (p=0.007) and the disease-free survival (p=0.005). According to multivariate analysis, HPV status is a significant predictor of both overall (p=0.02) and disease-free survival time (p=0.005). These results of this study suggest that HPV-negative patients with cervical carcinoma are have a significantly poorer prognosis after radiotherapy, and may be used as a marker in order to optimize the treatment of patients with this type of cancer.

    We compared efficacy of combined treatment of males with anogenital warts given intramuscular cycloferon or cycloferon electrophoresis. Patients with manifest HPV infection (n=107) were divided into two groups. Group 1 (n=72) received intramuscular cycloferon (2 ml 12.5% solution each other day for 10 days), group 2 (n=35) received cycloferon electrophoresis on genital region (2 ml 12.5% solution daily in 1-2 days, 5 injections). Measurements were made of local cytokines in urethral secretion, IFN-alpha, IFN-gamma, lactoferrin, sexual hormones (estradiol and testosterone) in blood serum before and after treatment. Focal immunophysiotherapy with cycloferon in combined treatment of males with anogenital warts vs intramuscular cycloferon treatment reduces recurrence rate 2 times, has no negative effect on serum level of sexual hormones, a course dose and duration of immunotherapy decreased 2-fold, is well tolerated, is not painful. Cycloferon electrophoresis has a more potent effect on improvement of local immunity. Thus, local immunophysiotherapy with cycloferon can be a method of choice in the treatment of manifest HPV infection in males.

    The carcinogenic biomarker aflatoxin B(1)-formamidopyrimidine 2,3-dihydro-2-(N-formyl)-2',5',6'-triamino-4'-4'-oxy-N-pyrimidyl-3-hydroxy-AFB(1) called AFB(1)-FAPY adduct, and Human Papilloma Virus (HPV) types 16 and 18 were quantified from DNA cervical scrapes from 40 women with cervical cancer (CC) and 14 healthy women as controls. The relationship between the AFB(1)-FAPY adduct and HPV types 16 and 18 was determined. Competitive inhibitory indirect ELISA was validated with 94% inhibition to quantify the AFB(1)-FAPY adducts in picograms per milligram of DNA (limit of detection = 0.1 pg/mg, and limit of quantification = 10 pg/mg), polymerase chain reaction and DNA sequencing to identify HPV types. The average concentration of AFB(1)-FAPY adducts/mg DNA in the CC cases was 1025 pg, 1420 pg with HPV16 and 630 pg sharing HPV18 (p = 0.03). In comparison, healthy controls had ≤ 2.6 pg/mg DNA, a statistically significant difference (p = 0.00006). The presence of AFB(1)-FAPY adduct increased six-fold the risk for CC between cases and controls, the odds ratio was 6.1 (95% CI = 1.4-25.4). There was a close relationship between the AFB(1)-FAPY adducts and HPV16 in CC samples.

    DNA microarray is a high-throughput technology used for detection and quantification of nucleic acid molecules and others of biological interest. The analysis is based on the specific hybridization between probe sequences deposited in array and a target ss-DNA amplified by PCR and functionalized by a fluorescent dye. Organic labels have well known disadvantages like photobleaching and low signal intensities, which put a limitation to the lower amount of DNA material that can be detected. Therefore for trace analysis the development of more efficient biomarkers is required. With this aim we present in this paper the synthesis and application of alternative hybrid nanosystems obtained by incorporating standard fluorescent molecules into monodisperse silica nanoparticles. Efficient application to the detection of Human Papilloma Virus is demonstrated. This virus is associated to the formation of cervical cancer, a leading cause of death by cancer for women worldwide. It is shown that the use of the novel biomarkers increases the optical signal of about one order of magnitude with respect to the free dyes or quantum dots in conventional instruments. This is due to the high number of molecules that can be accommodated into each nanoparticle, to the reduced photobleaching and to the improved environmental protection of the dyes when encapsulated in the silica matrix. The cheap and easy synthesis of these luminescent particles, the stability in water, the surface functionalizability and bio-compatibility make them very promising for present and future bio-labeling and bio-imaging applications.

    The incidence of the human papilloma virus (HPV) has not dropped in HIV-positive patients despite the discovery of antiretroviral therapy (ART). Our goal is to assess the prevalence of HPV in HIV patients and its relationship with the epidemiological and virological characteristics of HIV patients. Retrospective cohort of 965 patients diagnosed with HIV from 1998 to 2012. We analyzed patients' demographic factors and factors related to the HPV. Of the 965 patients examined, 333 consulted a dermatologist. Of these, 52 patients had genital warts (15.6%), 43 had common warts (12.9%) and 8% had both conditions. In total, 28.5% of patients had a skin lesion caused by HPV. This is the first longitudinal observational study carried out on HIV-positive patients in the era of ART in which HPV infection is the most common skin pathology. We observed a similar trend in countries with access to ART. This study spreads awareness on the importance of preventing HPV and the difficulty of treating it in HIV-positive patients.

    Full Text Available We report two cases of posterior third ventricular choroid plexus papilloma, one in an 8-month-old infant and another in a two-year-old child. These cases presented with features of obstructive hydrocephalus. Both these patients underwent a ventriculo-peritoneal (VP shunt surgery prior to the tumor excision. Following the VP shunt surgery both patients developed ascitis requiring exteriorization of the abdominal end of the shunt. There was a clear proof of CSF overproduction: 1400-1500 ml/ day in the eight-month-old infant and 900-1200 ml / day in the two-year-old child. In the former it was transient and could be treated with revision of the VP shunt whereas in the second case a ventriculo-arterial shunt had to be done. In the second case a staged reduction cranioplasty was also performed for an enormously enlarged head (head circumference—74 cm. Interesting clinical and radiological findings and useful management strategies are described.

    Over the past 30 years, human papilloma virus (HPV) has been shown to play a role in the development of various cancers. Most notably, HPV has been linked to malignant progression in neoplasms of the anogenital region. However, high-risk HPV has also been suggested to play a significant role in the development of cancers in other anatomic locations, such as the head and neck, lung, breast and bladder. In 2006, the first vaccine for HPV, Gardasil, was approved for the prevention of subtypes 6, 11, 16 and 18. A few years later, Cevarix was approved for the prevention of subtypes 16 and 18, the HPV subtypes most frequently implicated in malignant progression. Although increased awareness and vaccination could drastically decrease the incidence of HPV-positive cancers, these approaches do not benefit patients who have already contracted HPV and developed cancer as a result. For this reason, researchers need to continue developing treatment modalities, such as targeted immunotherapies, for HPV-positive lesions. Here, we review the potential evidence linking HPV infection with the development of non-anogenital cancers and the potential role of immunotherapy in the prevention and eradication of HPV infection and its oncogenic sequela.

    A najor current challenge and constraint in cervical cancer research is the development of vaccines against human papilloma virus (HPV) epitopes. Although many studies are done on epitope identification on HPVs, no computational work has been carried out for high risk forms which are considered to cause cervical cancer. Of all the high risk HPVs, HPV 16, HPV 18 and HPV 45 are responsible for 94% of cervical cancers in women worldwide. In this work, we computationally predicted the promiscuous epitopes among the E6 proteins of high risk HPVs. We identified the conserved residues, HLA class I, HLA class II and B-cell epitopes along with their corresponding secondary structure conformations. We used extremely precise bioinformatics tools like ClustalW2, MAPPP, NetMHC, EpiJen, EpiTop 1.0, ABCpred, BCpred and PSIPred for achieving this task. Our study identified specific regions 'FAFR(K)DL' followed by 'KLPD(Q)LCTEL' fragments which proved to be promiscuous epitopes present in both human leukocyte antigen (HLA) class I, class II molecules and B cells as well. These fragments also follow every suitable character to be considered as promiscuous epitopes with supporting evidences of previously reported experimental results. Thus, we conclude that these regions should be considered as the important for design of specific therapeutic vaccines for cervical cancer.

  13. Systemic and mucosal immune responses to sublingual or intramuscular human papilloma virus antigens in healthy female volunteers.

    Zhiming Huo

    Full Text Available The sublingual route has been proposed as a needle-free option to induce systemic and mucosal immune protection against viral infections. In a translational study of systemic and mucosal humoral immune responses to sublingual or systemically administered viral antigens, eighteen healthy female volunteers aged 19-31 years received three immunizations with a quadravalent Human Papilloma Virus vaccine at 0, 4 and 16 weeks as sublingual drops (SL, n = 12 or intramuscular injection (IM, n = 6. IM antigen delivery induced or boosted HPV-specific serum IgG and pseudovirus-neutralizing antibodies, HPV-specific cervical and vaginal IgG, and elicited circulating IgG and IgA antibody secreting cells. SL antigens induced ~38-fold lower serum and ~2-fold lower cervical/vaginal IgG than IM delivery, and induced or boosted serum virus neutralizing antibody in only 3/12 subjects. Neither route reproducibly induced HPV-specific mucosal IgA. Alternative delivery systems and adjuvants will be required to enhance and evaluate immune responses following sublingual immunization in humans.ClinicalTrials.govNCT00949572.

    One of the risk factors for squamous cell oropharyngeal carcinoma is infection with the human papilloma virus (HPV), with prevalences that vary depending on the geographical region.  To identify the most frequent HPV viral types in oropharyngeal cancer, the levels of expression and the physical condition of the viral genome.  Forty-six patients were included in the study from among those attending head and neck surgical services in the cities of Bogotá, Manizales and Bucaramanga. In the histopathological report all study samples were characterized as oropharyngeal squamous cell carcinoma. DNA extraction was subsequently performed for HPV genotyping and to determine the physical state of the viral genome, as well as RNA to determine viral transcripts using real-time PCR.  HPV prevalence in tumors was 21.74% (n=10) and the most common viral type was HPV-16 (nine cases). Viral expression for HPV-16 was low (one of 11 copies) and the predominant physical state of the virus was mixed (eight cases), with disruption observed at the E1 - E2 binding site (2525 - 3720 nucleotides).  The prevalence of HPV associated with oropharyngeal carcinoma among the Colombian study population was 21.7%, which is relatively low. The most frequent viral type was HPV-16, found in a mixed form and with low expression of E7, possibly indicating a poor prognosis for these patients.

    BACKGROUND: Lumbar hernia is a rare congenital or acquired defect of the posterior abdominal wall. The acquired type is more common and occurs mainly as an incisional defect after lfank surgery. Incarceration or strangulation of hernia contents is uncommon. METHOD: Segmental liver incarceration through a recurrent incisional lumbar defect was diagnosed in a 58 years old woman by magnetic resonance imaging. RESULTS: The patient underwent an open repair of the com-plicated hernia. An expanded polytetralfouoroethylene (e-PTFE) mesh was fashioned as a sublay prosthesis. She had an uncomplicated postoperative course. Follow-up examinations revealed no evidence of recurrence. CONCLUSIONS: Although lumbar hernia rarely results in incarceration or strangulation, early repair is necessary because of the risks of complications and the increasing dififculty in repairment as it enlarges. Surgical repair is often dififcult and challenging.

    Full Text Available Extra-abdominal desmoid tumors are known as aggressive fibromatosis (AFM. Synchronous and metachronous multicentric aggressive fibromatosis are rare lesions and pose dilemma in diagnosis and management. A rare and interesting case of recurrent multicentric, synchronous AFM is presented which to the best of our knowledge has not been reported earlier. A young male presented with well defined, hard, fixed swelling on the thigh. Resected tumor mass on histopathology was diagnosed as an extra abdominal fibromatosis. He presented again after two months with swelling at the same site; and two more swellings on the foot. Fine needle aspiration cytology (FNAC from all three sites was performed; and was suggestive of benign spindle cell lesion of fibrogenic origin with the possibility of multicentric synchronous recurrent aggressive fibromatosis.

    Full Text Available Clopidogrel is an oral thienopyridine and together with aspirin is a component of dual antiplatelet therapy for the prevention of stent thrombosis after intracoronary stent placement. The common adverse effects from its use are an increased risk of bleeding, neutropenia, and rash. Arthralgia and backache are also known to occur with its use. There have been case reports linking arthritis with the use of clopidogrel. We describe the case of a 64-year-old man who reported symptoms of fever and joint pains following initiation of therapy with clopidogrel. Acute-phase reactants were elevated. Laboratory and radiologic testing were unremarkable. Incidentally, he reported experiencing a similar arthritis after he received a loading dose of clopidogrel prior to a diagnostic coronary angiography in the past. The symptoms improved dramatically on discontinuation of clopidogrel. There was no recurrence of symptoms with prasugrel. This describes possibly the second incidence of recurrent arthritis with clopidogrel therapy.

    In recent years, gradient-based LSTM recurrent neural networks (RNNs) solved many previously RNN-unlearnable tasks. Sometimes, however, gradient information is of little use for training RNNs, due to numerous local minima. For such cases, we present a novel method: EVOlution of systems with LINear Outputs (Evolino). Evolino evolves weights to the nonlinear, hidden nodes of RNNs while computing optimal linear mappings from hidden state to output, using methods such as pseudo-inverse-based linear regression. If we instead use quadratic programming to maximize the margin, we obtain the first evolutionary recurrent support vector machines. We show that Evolino-based LSTM can solve tasks that Echo State nets (Jaeger, 2004a) cannot and achieves higher accuracy in certain continuous function generation tasks than conventional gradient descent RNNs, including gradient-based LSTM.

    Perimesencephalic hemorrhage (PMH) is a type of subarachnoid hemorrhage with excellent long-term outcomes. Only one well-documented case of in-hospital rebleeding after PMH is described in the literature, which occurred after initiating antithrombotic treatment because of myocardial ischemia. In this case report we describe a patient with PMH without antithrombotic treatment who had two episodes of recurrent bleeding on the day of ictus. In order to validate the radiological findings we conducted a case-control study. Six neuroradiologists and two neuroradiology fellows performed a blinded assessment of serial unenhanced head CT scans of eight patients with a perimesencephalic bleeding pattern (1 index patient, 6 patients with PMH, 1 patient with a perimesencephalic bleeding pattern and basilar artery aneurysm) to investigate a potential increase in amount of subarachnoid blood. A 56-year-old woman with a perimesencephalic bleeding pattern and negative CT angiography had after the onset headache two episodes with a sudden increase of the headache. Blinded assessment of serial head CTs of eight patients with a perimesencephalic bleeding pattern identified the patient who was clinically suspected to have two episodes of recurrent bleeding to have an increased amount of subarachnoid blood on two subsequent CT scans. Recurrent bleeding after PMH may also occur in patients not treated with antithrombotics. Even after early rebleeding, prognosis of PMH is excellent. Copyright © 2017 Elsevier Inc.

    Full Text Available Evidence is increasing that the integrity of sperm DNA may also be related to implantation failure and recurrent miscarriage (RM. To investigate this, the sperm DNA fragmentation in partners of 35 women with recurrent implantation failure (RIF following in vitro fertilization, 16 women diagnosed with RM and seven recent fathers (control were examined. Sperm were examined pre- and post-density centrifugation by the sperm chromatin dispersion (SCD test and the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL assay. There were no significant differences in the age of either partner or sperm concentration, motility or morphology between three groups. Moreover, there were no obvious differences in sperm DNA fragmentation measured by either test. However, whilst on average sperm DNA fragmentation in all groups was statistically lower in prepared sperm when measured by the SCD test, this was not seen with the results from the TUNEL assay. These results do not support the hypothesis that sperm DNA fragmentation is an important cause of RIF or RM, or that sperm DNA integrity testing has value in such patients. It also highlights significant differences between test methodologies and sperm preparation methods in interpreting the data from sperm DNA fragmentation tests.

    The risk of occupational human papillomavirus (HPV) transmission from patient to medical personnel during laser vaporization procedures remains controversial. The purpose of this study was to determine the risk of HPV transmission from the patient to the protective surgical masks, gloves and oral mucosa of medical personnel during the treatment of laryngeal papillomas and genital warts. The study involved five male patients scheduled for the surgical treatment of laryngeal papillomas, and five male patients undergoing carbon dioxide (CO(2)) laser treatment for urethral warts. Oral mucosa specimens were obtained from the study patients and the employees pre- and postoperatively. Samples were collected from the HPV-infected patient tissue, and from the surgical masks and gloves used by the employees. A total of 120 samples were analyzed for the presence of HPV DNA by PCR, using the degenerated MY09/11/HMB01 primers. After the papilloma procedures, the surgeons' gloves tested HPV positive in one of the five cases and those of the surgical nurse in three of the five cases. After the treatment of genital warts, HPV DNA corresponding to the patient tissue specimens was present in all the samples obtained from the surgical gloves of the operators. All oral mucosa samples obtained from 18 different employees tested HPV negative, as did the surgical mask specimens. According to our study, HPV may contaminate protective equipment, most of all surgical gloves, but transmission of HPV DNA to medical personnel is unlikely to occur provided that protective surgical gloves and masks are applied and disposed of properly.

    Histologic features of recurrent Hodgkin's disease (HD) after conventional therapy are well known, but few studies describe HD after bone marrow transplantation (BMT). Histologic material from 63 patients who underwent BMT performed to treat recurrent nodular sclerosing HD (NSHD) between 1985 and 1994 was examined; 13 of the 63 patients had histologically proved recurrent disease after BMT. Histologic material and clinical findings from the original diagnostic biopsy specimen and pre-BMT and post-BMT specimens were available from our study population of eight patients (five male, three female; age range, 16 to 38 years; median age, 27.5 years). Seven patients had recurrent NSHD after BMT; sites of recurrence included lymph nodes only (four patients), and lymph nodes and lung, lung and liver, and lung only (one patient each). In one patient, a high-grade non-Hodgkin's B-cell lymphoma developed in the large intestine 5 years after BMT. In another, disease progressed from grade 1 in the original biopsy specimen to grade 2 in both the pre-BMT and post-BMT recurrent HD biopsy specimens. Post-BMT biopsy specimens of recurrent HD with lung involvement revealed a substantial increase in sclerosis and fibroblastic features. Paraffin immunoperoxidase studies in seven patients demonstrated substantial change in phenotype of Reed-Stemberg cell variants in only one post-BMT recurrent HD specimen, which showed a +2 reaction with CD30 (Ki-1). No substantial differences in the reactive component were noted between the original biopsy specimen and pre-BMT and post-BMT specimens of recurrent disease. In summary, histologic findings of post-BMT recurrent NSHD do not differ significantly from those of the original diagnostic biopsy or pre-BMT recurrent HD specimens. The lung is the most common site of extranodal post-BMT recurrence. In one patient, high-grade non-Hodgkin's B-cell lymphoma developed after BMT performed to treat recurrent HD.

    Dendritic cells (DC) are often arranged in planar layers in tissues with high antigenic exposure, such as skin and mucosae. Providing an en face view, this arrangement optimizes in situ analysis regarding morphology (even of individual dendrites), topographic distribution (regular/clustered) and quantification. The few reports on human genital DC usually utilize single markers and conventional sections, restricting immunolabelling only to cell parts sectioned by the cut. To better assess DC in situ, we labelled epithelial sheets, prepared from fresh cervix biopsies, with antibodies to major histocompatibility complex (MHC)-CII, CD1a and Langerin, revealing (with each of these markers) a dense DC network in a planar-like, regular distribution. Using the hybrid capture system to detect the high-risk mucotropic human papilloma virus (HPV) group, 16 positive and five negative women were studied and the results were compared between these groups. DC frequency per area was substantially reduced (to ≈ 50% for the three markers) in samples from all HPV-infected patients compared with samples from controls. Unlike HPV– samples, Langerin+ DC in HPV+ cervix exhibited a highly accentuated dendritic appearance. We believe this to be the first study using these three DC-restricted markers (Langerin, CD1a and MHC-CII) in cervical epithelial sheets from high-risk HPV+ donors and also the first study to demonstrate the morphological and quantitative changes triggered by high-risk HPV infection. Cervical DC reduction in early, premalignant high-risk HPV infection might represent viral subversion strategies interfering with efficient antigen handling by the immune system's peripheral sentinels, the DC, perhaps hampering appropriate recruitment and subsequent development of effector (cytotoxic) T cells.

    Background: Prostatic adenocarcinoma by Prosate cancer (PCa) is the most prevalent cancer and the second cause of cancer-related death among men in the Western world. Human papilloma virus (HPV) may be considered as a preventable risk factor. In this study, we assessed the frequencies of HPV infection in prostatic adenocarcinoma and benign prostatic hyperplasia (BPH) cases in Northeast Mexico. Materials and Methods: A total of 87 paraffin-embedded blocks (from 25 and 62 patients with definite diagnoses of BPH and adenocarcinoma, respectively) were selected and subjected to INNOLiPA HPV Genotyping to detect 28 high- and low-risk HPV types. The rates of infection were compared in the two studied groups. Results: INNOLiPA HPV demonstrated great sensitivity for HPV detection on paraffin-embedded tissue. Global prevalence was 14.9% (13/87). HPV infection was positive in 19.4% (12/62) of patients with adenocarcinoma and 4.0% (1/25) of patients with BPH. HPV-11, which is considered to be low risk, was more prevalent. Interestingly, one patient with BPH and six with prostate cancer showed examples considered to be high risk (HPV-18, -51, -52, and -66). Conclusion: A higher rate of HPV infection among Mexican patients with prostatic carcinoma than among those with BPH was observed. HPV infections may thus contribute to the risk of prostate cancer. Further studies are required to elucidate any roles of HPV infection in prostate disease in Mexico and the effect of prevention and treatment of HPV infection on prostatic adenocarcinoma.

    The purpose of this study was to assess the knowledge and attitudes about human papilloma virus (HPV) and cervical cancer, and the acceptability of HPV vaccine among students, parents and teachers in secondary schools in Bangkok, Thailand. We conducted a school-based cross-sectional study at four public secondary schools in Bangkok. A total of 644 students aged 12-15 years, 664 parents and 304 teachers were recruited into the study. Data were collected by self-administered questionnaires. The percentages of students, parents and teachers who were willing to be vaccinated were 26, 49 and 43%, respectively. Forty-one percent of parents wanted their children to be vaccinated. Students, parents and teachers had a moderate knowledge of HPV, cervical cancer and the HPV vaccine with mean scores of 6.91 (SD = 1.75), 6.82 (SD = 1.88), and 6.70 (SD = 1.89), respectively. The attitudes of students, parents, and teachers were fair with scores of 3.46 (SD = 0.41), 3.52 (SD = 0.43), and 3.46 (SD = 0.47) out of 5, respectively. Twenty-nine percent of students and 36% of parents were willing to pay USD 14.3-28.5 per dose for the quadrivalent vaccine; 33% of teachers were willing to pay Thailand. The findings suggest the willingness to pay was relatively low and related to the price, while knowledge and attitudes regarding the importance of the HPV vaccine were fair particularly among parents and teachers. Greater effort may be needed to educate people regarding the cost and benefits of HPV vaccination before it would be more acceptable to parents, teachers and students in Thailand.

    Objective To evaluate the overexpression of cyclin G1 in cervical intraepithelial neoplasia (CIN) and cervical carcinoma, and the correlation between cyclin G1 and high-risk human papilloma virus (HPV) infection.Methods All of the specimens were obtained from the Department of Pathology of China-Japan Friendship Hospital from January 2000 to August 2004. We detected the expression of cyclin G1 with immunohistochemistry, HPV16/18infection with in situ hybridization, and high-risk HPV infection with Hybrid capture system Ⅱ (HC-Ⅱ) in normal group (25 cases), CIN Ⅰ (48 cases), CIN Ⅱ (56 cases), CIN Ⅲ (54 cases), and invasive cervical squamous-cell carcinoma (SCC, 31 cases).Results The positive rates of cyclin G1 expression in CIN (77. 85%) and SCC cervical tissues (87.10%) were significantly higher than normal (8.00%,P<0.01), and the intensities of cyclin G1 expression in CIN (40.60%)and SCC cervical tissues (61.51%) were significantly higher than normal (2.72%,P<0.05). The positive rates and intensities of cyclin G1 expression increased gradually with the grade of cervical lesions. High-risk HPV infection rates were higher in CIN and SCC than normal groups (P<0.05). There was a positive correlation between cyclin G1 expression and high-risk HPV infection detected with HC-Ⅱ (Kendall's tau-b =0.316, 0.269, 0.352, and 0. 474 in CIN Ⅰ, CINⅡ, CIN Ⅲ, and SCC, respectively, P<0.05).Conclusions Cyclin G1 is overexpressed in CIN and SCC. Cyclin G1 may be a biomarker for detecting CIN and SCC. Cyclin G1 may play an important role in the oncogenesis of CIN and SCC by high-risk HPV infection.

    The epidemiology of oral cancer is changing. From 1988 to 2004, there has been a dramatic increase in Human Papilloma virus (HPV) positive oropharyngeal squamous cell carcinoma (OPC) in the U.S. At the same time there have been decreasing rates of OPC associated with the traditional risk factors of smoking and alcohol consumption. The epidemiology of oral cancer is changing. As the epidemiology changes, it is important that the dental community recognize these factors. The goal of this study was to assess the baseline level of knowledge about HPV and OPC within the Texas dental community. Practicing dentists and dental hygienists from Texas dental professional networks and dental students from the three Texas schools of dentistry were recruited to participate in the study. Participants were requested to access and complete a 7-item online survey. To ensure anonymity, a third party practice facilitator or department administrator disseminated the survey link to participants. Of the 457 surveys completed, 100% of respondents reported conducting oral soft tissue examinations at least annually. However, only 73% included the oropharynx in their exam. Less than 50% of dental professionals selected the correct location of the greatest increase in oral cancer incidence during the last 10 years. Less than 30% of each of the groups answered correctly in indicating the age group with the most rapidly increasing incidence of oral cancer. Approximately 40% of all groups indicated that a biopsy from the posterior oropharynx should be tested for HPV. Survey results across Texas dentists, dental hygienists, and Texas dental students demonstrated a lack of knowledge of the changing profile of oral cancer regarding HPV-associated OPC. This aim of this initial phase was to determine the baseline level of knowledge surrounding the risks associated with oropharyngeal cancer in the survey population. Our goal is to utilize these findings to develop educational interventions that will

    Photodynamic therapy (PDT) is a promising new modality to treat malignant neoplasms including superficial skin cancers. In our search for an ideal photosensitizer for PDT, Pc 4, a silicon phthalocyanine, has shown promising results both in in vitro assays and in implanted tumors. In this study we assessed the efficacy of Pc 4 PDT in the ablation of murine skin tumors; and the evidence for apoptosis during tumor ablation was also obtained. The Pc 4 was administered through tail vein injection to SENCAR mice bearing chemically induced squamous papillomas, and 24 h later the lesions were illuminated with an argon ion-pumped dye laser tuned at 675 nm for a total light dose of 135 J/cm2. Within 72-96 h, almost complete tumor shrinkage occurred; no tumor regrowth was observed up to 90 days post-PDT. As evident by nucleosome-size DNA fragmentation, appearance of apoptotic bodies in hematoxylin and eosin staining and direct immunoperoxidase detection of digoxigenin-labeled genomic DNA in sections, apoptosis was clearly evident 6 h post-PDT at which time tumor shrinkage was less than 30%. The apoptotic bodies, as evident by the condensation of chromatin material around the periphery of the nucleus and increased vacuolization of the cytoplasm, were also observed in electron microscopic studies of the tumor tissues following Pc 4 PDT. The extent of apoptosis was greater at 15 h than at 6 and 10 h post-PDT. Taken together, our results clearly show that Pc 4 may be an effective photosensitizer for PDT of nonmelanoma skin cancer, and that apoptosis is an early event during this process.

    Several types of virus have been implicated in the development of head and neck tumors. However, until now sinonasal adenocarcinomas (ACN) have not been studied. The aim of this study is to screen a series of ACN for the presence of a number of viruses known to play a role in cancer. Viral DNA sequences of herpes simplex virus, Epstein-Barr, varicela zoster, human papilloma, cytomegalovirus, and adenovirus were analysed by PCR in 37 primary ACN. Three tumors (8.1%) were positive for Epstein-Barr virus and 1 case (2.7%) for cytomegalovirus. Viral infections do not seem to play a role in the etiology of ACN.

  14. Recurrent glomerular disease after kidney transplantation.

    2017-08-21

    With improving short-term kidney transplant outcomes, recurrent glomerular disease is being increasingly recognized as an important cause of chronic allograft failure. Further understanding of the risks and pathogenesis of recurrent glomerular disease enable informed transplant decisions, along with the development of preventive and treatment strategies. Multiple observational studies have highlighted differences in rates and outcomes for various recurrent glomerular diseases, although these rates have not markedly improved over the last decade. Emerging evidence supports use of rituximab to treat recurrent primary membranous nephropathy and possibly focal segmental glomerulosclerosis (FSGS), whereas eculizumab is effective in glomerular diseases associated with complement dysregulation [C3 glomerulopathy (C3G) and atypical hemolytic uremic syndrome (aHUS)]. Despite the potential for recurrence in the allograft, transplant remains the optimal therapy for patients with advanced chronic kidney disease (CKD) secondary to primary glomerular disease. Biomarkers and therapeutic options necessitate accurate pretransplant diagnoses with opportunities for improved surveillance and treatment of recurrent glomerular disease posttransplant.

    OBJECTIVE: We performed an individual participant data (IPD) metaanalysis to calculate the recurrence risk of hypertensive disorders of pregnancy (HDP) and recurrence of individual hypertensive syndromes. STUDY DESIGN: We performed an electronic literature search for cohort studies that reported...... that are included in our IPD, the recurrence rate of a HDP was 20.7% (95% CI, 20.4-20.9%). Recurrence manifested as preeclampsia in 13.8% of the studies (95% CI,13.6-14.1%), gestational hypertension in 8.6% of the studies (95% CI, 8.4-8.8%) and hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome...... delivery, and perinatal death. Normotensive women experienced chronic hypertension after pregnancy more often after experiencing recurrence (odds ratio, 3.7; 95% CI, 2.3-6.1). CONCLUSION: Among women that experience hypertension in pregnancy, the recurrence rate in a next pregnancy is relatively low...

    Chimera states, characterised by coexistence of coherence and incoherence in coupled dynamical systems, have been found in various physical systems, such as mechanical oscillator networks and Josephson-junction arrays. We used recurrence plots to provide graphical representations of recurrent patterns and identify chimera states. Moreover, we show that recurrence plots can be used as a diagnostic of chimera states and also to identify the chimera collapse.

    Hirata, Yoshito; Komuro, Motomasa; Horai, Shunsuke; Aihara, Kazuyuki

    It is practically known that a recurrence plot, a two-dimensional visualization of time series data, can contain almost all information related to the underlying dynamics except for its spatial scale because we can recover a rough shape for the original time series from the recurrence plot even if the original time series is multivariate. We here provide a mathematical proof that the metric defined by a recurrence plot [Hirata et al., 2008] is equivalent to the Euclidean metric under mild conditions.

    Surgically treated patients with arteriovenous malformations (AVMs) are considered cured when the postoperative angiogram proves complete resection. However, despite no residual nidus or early draining vein on postoperative angiogram, rare instances of AVM recurrence have been reported in adults. In this paper, the authors present a case of a 24-year-old woman with asymptomatic double recurrence of her cerebral AVM after angiographically proven complete resection. To the authors' knowledge, this patient represents the first case with double de novo asymptomatic recurrence of Spetzler-Martin grade I AVM. Also, she represents the first case with unique AVM criteria in each recurrence.

    The odontogenic keratocyst (OKC) is a developmental odontogenic cyst typically occurring in the jaws. Since the first description of OKC was published in 1956, the lesion has been of particular interest because of its specific histopathologic features, high recurrence rate, and aggressive behavior. Recurrences most commonly arise within bone at the site of the original cyst. However, as lining cells may find their way into surrounding tissues either from implantation during surgery or from cortical perforation recurrences may arise at a distance from the original cyst. Here, we report a rare case of recurrent OKC which was first developed in mandible and recurred within the masticatory space.

    2015-01-01

    Ameloblastic fibroma (AF), a slow-growing, benign tumor of odontogenic origin, represents 2% of all odontogenic tumors. Jaw expansion is among the most common symptoms, with diagnosis often made through routine radiographs. AFs have a recurrence rate of 18% to 43.5% after conservative enucleation. Long-term follow-up by both the surgeon and referring dentist is recommended, since recurrence may be due to regrowth of residual tumor undergoing malignant transformation. Aggressive management is recommended for local tumor recurrence. En bloc excision with bone grafting, followed by implant reconstruction, can be curative and preservative of function. Treatment of a recurrent AF is described.

    Full Text Available Background: Despite the effectiveness of pharmacotherapy in acute phase of bipolar mood disorder, patients often experience relapses or recurrent episodes. Hospitalization of patients need a great deal of financial and humanistic resources which can be saved through understanding more about the rate of relapse and factors affecting this rate. Methods: In a descriptive analytical study, 380 patients with bipolar disorder who were hospitalized in psychiatric emergency ward of Noor hospital, Isfahan, Iran, were followed. Each patient was considered for; the frequency of relapse and recurrence, kind of pharmachotherapy, presence of psychotherapeutic treatments, frequency of visits by psychiatrist and the rank of present episode. Results: The overall prevalence of recurrence was 42.2%. Recurrence was lower in patients using lithium carbonate or sodium valproate or combined therapy (about 40%, compared to those using carbamazepine (80%. Recurrence was higher in patients treated with only pharmacotherapy (44.5% compared to those treated with both pharmacotherapy and psychotherapy (22.2%. Patients who were visited monthy by psychiatrist had lower rate of recurrence compared to those who had irregular visits. Conclusion: The higher rate of recurrence observed in carbamazepine therapy may be due to its adverse reactions and consequently poor compliance to this drug. Lower rates of recurrence with psychotherapy and regular visits may be related to the preventive effects of these procedures and especially to the effective management of stress. Keywords: Bipolar Mood Disorder, Recurrence, Relapse.

    The surgical management of mammary intraductal papilloma without atypia (IDP) identified at core-needle biopsy (CNB) is controversial. This study assessed the rate of upgrade to carcinoma at surgical excision (EXC). This study identified women with a CNB diagnosis of intraductal papilloma without atypia or carcinoma at a cancer center between 2003 and 2013. Radiologic-pathologic concordance was assessed for all cases, and discordant cases were excluded. The radiologic and clinicopathologic features of patients with a CNB diagnosis of IDP were correlated with an upgrade to carcinoma at EXC. The study population consists of 189 women with 196 IDPs; 166 women (171 IDPs) underwent EXC. The upgrade rate was 2.3% (4 of 171). The upgraded lesions were 2 invasive lobular carcinomas and 2 cases of ductal carcinoma in situ (DCIS). One case of DCIS involved the residual IDP, whereas the other 3 carcinomas were ≥ 8 mm away. Twenty-four women (25 IDPs) did not undergo EXC and had stable imaging on follow-up (median, 23.5 months). The upgrade rate at EXC for IDPs diagnosed at CNB with radiologic-pathologic concordance was 2.3%. These findings suggest that observation is appropriate for patients with radiologic-pathologic concordant CNB yielding IDP, regardless of its size. Cancer 2016. © 2016 American Cancer Society.

    Full Text Available The Human Papilloma Virus (“HPV” is a common sexually transmitted disease that has infected approximately 79 million men and women in the United States alone. A vaccination is available but in order to be effective it must be received prior to becoming sexually active and recipients must complete a three-dose sequence. In this article we explore the predisposing, enabling and need-based factors associated with parents’ or guardians’ decision to have their child initiate, continue and complete the Human Papilloma Virus (HPV vaccine. The data file includes 5531 parents and guardians with presumptive knowledge regarding the number of HPV vaccination their child received. Data includes information on the child (e.g. child׳s age as well as the adult respondent (e.g. health insurance status.

    Full Text Available We report a patient who had rhinogenic intracranial complication with postoperative frontal sinus pyocele and inverted papilloma in the nasal cavity. A 72-year-old woman had undergone surgery for frontal sinusitis via external incision at another hospital 13 years previously. Left-sided hemiparesis appeared in the patient and gradually worsened. Five days later, she exhibited disorientation, abnormal behavior, poor articulation, and difficulty in standing. Therefore, she was taken to the neurosurgery department by ambulance. An extensive frontal sinus pyocele was suspected, and a cerebral abscess and edema of the frontal lobe were observed on magnetic resonance imaging. After antibiotics, steroid and glycerol were administered for a few weeks; disorientation and left hemiparesis improved. Next, craniotomy for complete removal of the brain abscess by neurosurgeons and endoscopic endonasal surgery by otolaryngologists were carried out at the same surgery. From the analysis of the pathological mucosa sample taken from the right ethomoidal sinus during surgery, an inverted papilloma was diagnosed. The patient completely recovered and is currently receiving follow-up examination. Regarding rhinogenic intracranial complications, ascertaining clinical condition in order to determine the need for either immediate radical surgery, or for curative surgery after waiting for improvement of the overall body condition by conservative management, is still needed.

    Neuroleptic malignant syndrome (NMS) is a rare idiosyncratic reaction associated with the use of neuroleptics that has an incidence of 0.02 to 3% among patients taking these drugs. This is a very serious complication with a mortality rate that reaches 10-20%. It is therefore very important to have high clinical suspicion and use appropriate criteria to objectify this clinical picture early, stopping the medication causing the picture and to avoid the subsequent complications as much as possible that would be responsible for both its mortality and sequels. We present that case of an 81-year old woman who was admitted to the Psychiatric Hospitalization Unit (PHU) for a depressive episode with psychotic symptoms who developed a neuroleptic malignant syndrome (NMS) when Haloperidol was introduced. After its suspension and subsequent clinical recovery, antipsychotic treatment with Risperidone was reintroduced and she suffered a recurrence of NMS. Finally, significant improvement was achieved with several sessions of electroshock therapy (EST).

    Recurrent pregnancy loss (RPL) was defined as two or more miscarriages. Antiphospholipid syndrome, uterine anomalies, and parental chromosomal abnormalities, particularly translocation and abnormal embryonic karyotype, are identifiable causes of RPL. Obesity may increase the risk of sporadic miscarriage in pregnancies conceived spontaneously. Obesity with body mass index (BMI)>30 kg/m2 is an independent risk factor for further miscarriage with odds ratio 1.7-3.5 in patients with early RPL. Obesity is associated with euploid miscarriage. Unexplained RPL with euploid embryo might be a common disease caused by both polymorphisms of multiple susceptibility genes and lifestyle factors such as women's age, obesity, and smoking. Patients with a history of RPL were found to have a higher risk of cardiovascular disease, celiac disease, gastric ulcer, gastritis, and atopic dermatitis. No study has examined the effect of weight loss on the prevention of further miscarriage in patients with RPL.

    Full Text Available Apoptosis is an interactive and dynamic biological process involved in all phases of embryogenesis. We aimed to study the effect of placental apoptosis on recurrent miscarriage (RM. Placental tissue samples were collected from 40 women with RM (study group and 30 women with sporadic spontaneous abortion (control group. Samples were prepared and stained immunohistochemically with markers for both the apoptotic protein (p53 and anti-apoptotic Bcl-2 antibodies. Our results showed that expression of the apoptotic (p53 protein was significantly increased in the placental tissues of the RM group (p = 0.003. By contrast, the expression of anti-apoptotic (Bcl-2 antibodies was significantly increased in the placental tissues of the control group (p = 0.025. We concluded that placental apoptosis plays a crucial role in pregnancy continuation. However, increased p53 expression in placental tissue in early pregnancy could negatively affect pregnancy continuation.

    Full Text Available Current first-line treatment regimens combine surgical resection and chemoradiation for Glioblastoma that provides a slight increase in overall survival. Age on its own should not be used as an exclusion criterion of glioblastoma multiforme (GBM treatment, but performance should be factored heavily into the decision-making process for treatment planning. Despite aggressive initial treatment, most patients develop recurrent diseases which can be treated with re-resection, systemic treatment with targeted agents or cytotoxic chemotherapy, reirradiation, or radiosurgery. Research into novel therapies is investigating alternative temozolomide regimens, convection-enhanced delivery, immunotherapy, gene therapy, antiangiogenic agents, poly ADP ribose polymerase inhibitors, or cancer stem cell signaling pathways. Given the aggressive and resilient nature of GBM, continued efforts to better understand GBM pathophysiology are required to discover novel targets for future therapy.

Complete surgical resection offers the best chance of long-term survival. However, despite complete resection, ACC is associated with high recurrence rates. This review will discuss the management of recurrent ACC in adults following complete surgical resection. Management should take place in a specialist center and treatment decisions must consider the individual tumor biology of each case of recurrence. Given the fact that ACC commonly recurs, management to prevent recurrence should be considered from initial diagnosis with the use of adjuvant mitotane. Close follow up with clinical examination and imaging is important for early detection of recurrent disease. Locoregional recurrence may be isolated, and repeat surgical resection should be considered along with mitotane. The use of radiotherapy in ACC remains controversial. Systemic recurrence most often involves liver, pulmonary, and bone metastasis and is usually managed with mitotane, with or without combination chemotherapy. There is a limited role for surgical resection in systemic recurrence in selected patients. In all patients with recurrent disease, control of excessive hormone production is an important part of management. Despite intensive management of recurrent ACC, treatment failure is common and the use of clinical trials and novel treatment is an important part of management.

    Full Text Available Approximately 30-50% of idiopathic optic neuritis (ION patients experience one or multiple episodes of recurrence. The aim of this study was to search for risk factors for ION recurrence.Clinical data on hospitalized patients diagnosed with ION between January 2003 and January 2011 at the First Affiliated Hospital of Guangxi Medical University were retrospectively collected. Univariate and multivariate analyses were performed on factors that might cause ION recurrence. In total, 115 ION cases (32 recurrent and 83 non-recurrent cases with complete data were analyzed. The length of the follow-up period ranged from 12 to 108 months (median: 42 months.The univariate analysis showed that the recurrence rate for unilateral ION was higher than that for bilateral ION (40% vs. 12%, p=0.001. Underlying diseases had a significant impact on recurrence (p<0.001: the recurrence rates due to neuromyelitis optica (NMO, multiple sclerosis (MS, demyelinating lesions alone of the central nervous system, and unknown causes were 89%, 70%, 41%, and 8.7%, respectively. The multivariate analysis showed that the factors causing relatively high recurrence rates included NMO (odds ratio [OR], 73.5; 95% confidence interval [CI], 7.3 to 740.9, MS (OR, 33.9; 95% CI, 5.2 to 222.2, and demyelinating lesions alone (OR, 8.9; 95% CI, 2.3 to 34.4, unilateral involvement (OR, 5.7; 95% CI, 1.5 to 21.3, relatively low initial glucocorticoid dosage (equivalent to ≤ 100 mg prednisone/day (OR, 4.3; 95% CI, 1.0 to 17.9.Underlying diseases, laterality (unilateral or bilateral, and initial glucocorticoid dosage are important risk factors of ION recurrence. Clinical physicians are advised to treat ION patients with a sufficient dose of glucocorticoid in the initial treatment stage to reduce the recurrence risk.

  2. Investigation of hTERT gene expression levels in two cell lines infected by high-risk human papilloma virus

    2016-07-01

    Full Text Available Background: Human papilloma virus (HPV is one of the most important factors in cervical cancer. Viral sequences are integrated into the host cell genome. In mild cases the virus causes skin damages, in severe cases it leads to cancer. Like many other cancers, telomerase gene expression was increased in cervical cancer. This enzyme is a reverse transcriptase that contains two common subunits: i catalytic protein called human telomerase reverse transcriptase (hTERT and, ii RNA sequence called hTR. hTERT expression is hardly found in any somatic tissues. Detection of high telomerase activity in human cells, lead to tumor genesis. So hTERT can be used as a diagnostic tool in cancer detection. Methods: This experimental study was carried out from May 2013 to April 2014 in Nanobiotechnology Research Center, Baqiyatallah University of Medical Sciences in Tehran, Iran. Caski and Hela cancer cell lines were used which contain HPV16 and HPV18 respectively. Cell lines were cultured and total RNA was extracted. Following normalization agent glyceraldehyde-3-phosphate dehydrogenase (GADPH, hTERT expression level was determining by real-time PCR method. For each sample, the expression level of hTERT and GAPDH were quantified as copy numbers (per reaction using the standard curve. Finally, hTERT levels in Hela and Caski cell lines were compared quantitatively by t-test using GraphPad statistic software version 5 (San Diego, CA, USA. Results: According to the charts real-time PCR, hTERT gene expression in Hela and Caski cancer cell lines is significantly different (t=0.0319. Conclusion: All results confirm that hTERT expression levels in Hela and Caski cell lines are significantly different and the level of hTERT expression in the Caski cell line was slightly higher than that of Hela cell line. The significant difference between hTERT mRNA expression levels reported here could be used as a tumor marker for HPV16 and HPV18 in cervical cancer.

    A 10-month-old girl with a Brachmann-Cornelia de Lange syndrome and a choroid plexus papilloma of the brain was studied at the Hospital Infantil de México Federico Gómez (HIMFG) in Mexico City. Presumptive papilloma of the third ventricle was evidenced on CT and MR images and removed. Pathological analysis confirmed its origin. A posterior radiosurgery was required due to a tumor relapse. Karyotypes (GTG bands) of the patient and her parents undertaken at HIMFG were normal. Array comparative genomic hybridization (array CGH) analyses of blood DNA of the patient and her parents carried out at BlueGnome's Laboratory in Cambridge, UK, set in evidence amplification of genes SPNS2, GGT6, SMTNL2, PELP1, MYBBP1A, and ALOX15 in chromosome 17p of the patient. Since MYBBP1A is a proto-oncogene and ALOX15 participates in the development of cancer and metastases of tumors, further fluorescent in situ hybridization (FISH) analyses of these two genes were implemented at HIMFG. Amplification of the two genes was found in the tumor of the case under study but not in an unrelated papilloma of the choroid plexus. Further analyses of the association of choroid plexus papillomas with disorders of psycho-neural development and its relationship to molecular genetic modifications at chromosome 17p are now under way at HIMFG.

    Full Text Available Recurrent respiratory papillomatosis (RRP, which is caused exclusively by human papilloma virus (HPV, is a rare condition characterized by recurrent growth of benign papillomata in the respiratory tract. The papillomata can occur anywhere in the aerodigestive tract but most frequently in the larynx, affecting both children and adults. The management of this entity remains still challenging since no specific definitive treatment exists. Nevertheless, novel surgical interventions as well as several adjuvant therapies have shown promising results in the long-term palliative management of this debilitating disease. Despite its mostly benign nature, RRP may cause significant morbidity and mortality because of its unpredictable clinical course and especially its tendency, albeit infrequent, for malignant transformation. In this article, we present two patients with RRP; one underwent bronchoscopic laser ablation in combination with inhaled interferon-alpha administration that led to a long-term regression of the disease while the other patient was diagnosed with transformation to squamous cell lung carcinoma with fatal outcome. We include a review of the current literature with special emphasis on RRP management and the potential role of HPV in the development of lung cancer.

    The chapters in this book originate from the research work and contributions presented at the Sixth International Symposium on Recurrence Plots held in Grenoble, France in June 2015. Scientists from numerous disciplines gathered to exchange knowledge on recent applications and developments in recurrence plots and recurrence quantification analysis. This meeting was remarkable because of the obvious expansion of recurrence strategies (theory) and applications (practice) into ever-broadening fields of science. It discusses real-world systems from various fields, including mathematics, strange attractors, applied physics, physiology, medicine, environmental and earth sciences, as well as psychology and linguistics. Even readers not actively researching any of these particular systems will benefit from discovering how other scientists are finding practical non-linear solutions to specific problems. The book is of interest to an interdisciplinary audience of recurrence plot users and researchers interested in time...

    2007-12-01

    We propose recurrence plots (RPs) to characterize the stickiness of a typical area-preserving map with coexisting chaotic and regular orbits. The difference of the recurrence properties between quasiperiodic and chaotic orbits is revisited, which helps to understand the complex patterns of the corresponding RPs. Moreover, several measures from the recurrence quantification analysis are used to quantify these patterns. Among these measures, the recurrence rate, quantifying the percentage of black points in the plot, is applied to characterize the stickiness of a typical chaotic orbit. The advantage of the recurrence based method in comparison to other standard techniques is that it is possible to distinguish between quasiperiodic and chaotic orbits that are temporarily trapped in a sticky domain, from very short trajectories.

    2013-07-01

    The incidence of Well-differentiated Thyroid Carcinoma (WDTC) has been increasing over the past several decades. Consequently, so has the incidence of recurrence, which ranges from 15% to 30%. Factors leading to increased risk of recurrence are well described. However, the impact of local and regional recurrence is not well understood, but distant recurrence dramatically reduces 10-year survival to 50%. Recurrent WDTC has several established options for treatment; Observation, Radioactive Iodine (RAI), Surgery and External Beam Radiotherapy (EBRT). Novel treatments such as radiofrequency ablation (RFA) and percutaneous ultrasound-guided ethanol injection (PUEI) are beginning to gain popularity and have promising early results. A review of the current literature, outcome measurements and a strategy for revision surgery within the central neck compartment are discussed within this manuscript.

    Chondroblastomas account for 80% of cases. Local recurrence rates of ≤38% have been reported, most often because of inadequate resection, and have been associated with malignant conversion and metastasis. Adjuvant therapies can help minimize the incidence of local recurrence. Long-term follow-up examinations are recommended, given the protracted interval that can exist between recurrence and the potential for malignant conversion and metastasis. We present the case of a young, healthy, active male with a calcaneal chondroblastoma and associated pathologic fracture whose initial treatment consisted of curettage, hydrogen peroxide lavage, and allogeneic bone grafting. Recurrence developed at 15 months postoperatively and was treated with repeat curettage, high-speed burring, and reconstruction with steel Steinman pins and polymethylmethacrylate, resulting in no pain or recurrence at the 5-month follow-up point.

    Liver transplantation (LT) is the most effective treatmentmodality for end stage liver disease caused by manyetiologies including autoimmune processes. That said,the need for transplantation for autoimmune hepatitis(AIH) and primary biliary cirrhosis (PBC), but not forprimary sclerosing cholangitis (PSC), has decreasedover the years due to the availability of effective medicaltreatment. Autoimmune liver diseases have superiortransplant outcomes than those of other etiologies. WhileAIH and PBC can recur after LT, recurrence is of limitedclinical significance in most, but not all cases. RecurrentPSC, however, often progresses over years to a stagerequiring re-transplantation. The exact incidence andthe predisposing factors of disease recurrence remaindebated. Better understanding of the pathogenesis andthe risk factors of recurrent autoimmune liver diseasesis required to develop preventive measures. In thisreview, we discuss the current knowledge of incidence,diagnosis, risk factors, clinical course, and treatmentof recurrent autoimmune liver disease (AIH, PBC, PSC)following LT.

    Objective To describe management and oncologic outcomes for patients who develop locoregional recurrence (LRR) or distant metastasis (DM) following transoral robotic surgery for human papilloma virus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC). Study Design Case series with chart review. Setting Tertiary care referral center. Subjects and Methods A total of 286 patients with HPV-positive OPSCC who underwent transoral robotic surgery-based treatment from May 2007 to May 2015. Results Of 286 patients (12.2%), 35 met inclusion criteria. Of these, 19 experienced an LRR and 16 developed a DM; 2 patients with LRR subsequently developed DM. In those patients with an LRR, 79% had T1/T2 tumors, and 47% had N0/N1 nodal disease, compared with 75% and 6% in the DM group, respectively. The median time to LRR or DM was 0.6 years (interquartile range [IQR], 0.4-1.0) and 1.8 years (IQR, 1.0-2.1), respectively. Salvage treatment with intent to cure was attempted in 23 patients (16 LRR, 7 DM). The median time from LRR or DM to last follow-up for the 18 patients who were still alive after salvage was 1.9 years (IQR, 0.4-3.8; range, 7 days-6.2 years). Estimated cancer-specific survival rates at 3 years following intent-to-cure treatment were 63% (95% CI, 39-100; number still at risk, 5) in the LRR group and 100% (95% CI, 100-100; number still at risk, 2) in the DM group. Conclusion Overall, LRR and DM for HPV-positive OPSCC following transoral robotic surgery-based therapy are infrequent. In our subset of patients who underwent intent-to-cure treatment, cancer-specific survival rates were favorable. Therefore, aggressive salvage treatment for LRR and DM for HPV-positive OPSCC should be recommended for appropriate candidates.

    Lidocaine has a concentration-dependent effect on seizures. Concentrations above 15 μg/mL frequently result in seizures in laboratory animals and human. We report a case of central nervous system (CNS) lidocaine toxicity and recurrent seizure after erroneous ingestion of lidocaine solution. A 4-year-old boy presented to the Emergency Department of Imam Hospital of Sari in December 2013 due to tonic-clonic generalized seizures approximately 30 min ago. 3 h before seizure, his mother gave him 2 spoons (amount 20-25 cc) lidocaine hydrochloride 2% solution instead of pediatric gripe by mistake. Seizure with generalized tonic-clonic occurred 3 times in home. Neurological examination was essentially unremarkable except for the depressed level of consciousness. Personal and medical history was unremarkable. There was no evidence of intracranial ischemic or hemorrhagic lesions in computed tomography scan. There were no further seizures, the condition of the patient remained stable, and he was discharged 2 days after admission. The use of viscous lidocaine may result in cardiovascular and CNS toxicity, particularly in children. Conservative management is the best option for treatment of lidocaine induced seizure.

    AIM: To investigate the effects of autologous tumor vaccine on recurrence of hepatocellular carcinoma (HCC).METHODS: Sixty patients with HCC who had undergone curative resection, were randomly divided into HCC vaccine group and control group. Three vaccinations at 2-wk intervals were performed after curative hepatic resection. Delayedtype- hypersensitivity (DTH) test was performed before and after vaccination. Primary endpoints were the time of recurrence.RESULTS: Four patients in control group and 6 patients in HCC vaccine group were withdrawn from the study. The vaccine containing human autologous HCC fragments showed no essential adverse effect in a phase Ⅱ clinical trial and 17 of 24 patients developed a DTH response against the fragments. Three of 17 DTH-positive response patients and 5 of 7 DTH- negative response patients had recurrences after curative resection. After the operation,1-, 2- and 3-year recurrence rates of HCC vaccine groupwere 16.7%, 29.2% and 33.3%, respectively. But, 1-, 2- and3-year recurrence rates of the control group were 30.8%,53.8% and 61.5%, respectively. The time before the first recurrence in the vaccinated patients was significantly longer than that in the control patients (P<0.05).CONCLUSION: Autologous tumor vaccine is of promise in decreasing recurrence of human HCC.

    Background and Aims. Studies have shown effects of diet on gut microbiota. We aimed to identify foods associated with recurrent Clostridium difficile infection (CDI). Methods. In this cross-sectional survey, consecutive patients diagnosed with CDI were identified by electronic medical records. Colitis symptoms and positive Clostridium difficile assay were confirmed. Health-care onset-health-care facility associated CDI was excluded. Food surveys were mailed to 411 patients. Survey responses served as the primary outcome measure. Spearman's rank correlation identified risk factors for CDI recurrence. Results. Surveys were returned by 68 patients. Nineteen patients experienced CDI recurrence. Compared to patients without CDI recurrence, patients with CDI recurrence had more antibiotics prescribed preceding their infection (p = 0.003). Greater numbers of the latter also listed tea (p = 0.002), coffee (p = 0.013), and eggs (p = 0.013), on their 24-hour food recall. Logistic regression identified tea as the only food risk factor for CDI recurrence (adjusted OR: 5.71; 95% CI: 1.26-25.89). Conclusion. The present results indicate a possible association between tea and CDI recurrence. Additional studies are needed to characterize and confirm this association.

    Identifying children with febrile seizure who are at risk for recurrence is important so that special attention can be given to them. The objective of this study was to identify the risk factors for recurrence of febrile seizures in children. This prospective hospital based study was conducted from July 2013 to August 2014 'among children of 6 months to 6 years of age at Bishweshwar Prasad Koirala Institute of Health Sciences (BPKIHS), Nepal. Children meeting the selection criteria were enrolled in study. Clinical, investigation, treatment and outcome parameters were analyzed. A total of 92 children with febrile seizure were enrolled in study. Males accounted for 70% and females 30%. Simple febrile seizure was present in 48% and complex febrile seizures were seen in 52%. Recurrence of seizure was seen in one third of cases. Loss of consciousness was most common post-ictal phenomenon followed by confusion and lethargy. Upper respiratory infection was the most common precipitating factor. Generalized Tonic Clonic Seizure was the most common seizure type present in 79% of cases. Significant risk factors for recurrence occurred in males (p=0.088), age less than 1 year (p=0.003). Most of the recurrence occurred within one year of first seizure. Febrile Seizure is common in males. Almost one third of children with febrile seizure are at risk for recurrence. The significant risk factors for recurrences are male gender and age <1year.

    Metallothioneins (MTs) are intracellular thiol-rich heavy metal-binding proteins which join trace metal ions protecting cells against heavy metal toxicity and regulate metal distribution and donation to various enzymes and transcription factors. The goal of this study was to identify the − 5 A/G (rs28366003) single-nucleotide polymorphism (SNP) in the core promoter region of the MT2A gene, and to investigate its effect on allele-specific gene expression and Cd, Zn, Cu and Ni content in sinonasal inverted papilloma tissue (IP), with non-cancerous sinonasal mucosa (NCM) as a control. The MT2A promoter region − 5 A/G SNP was identified by restriction fragment length polymorphism using 117 IP and 132 NCM. MT2A gene analysis was performed by quantitative real-time PCR. Metal levels were analyzed by flame atomic absorption spectrometry. The frequency of A allele carriage was 99.2% and 100% in IP and NCM, respectively. The G allele carriage was detected in 23.9% of IP and in 12.1% of the NCM samples. As a result, a significant association of − 5 A/G SNP in MT2A gene with mRNA expression in both groups was determined. A significant association was identified between the − 5 A/G SNP in the MT2A gene with mRNA expression in both groups. A highly significant association was detected between the rs28366003 genotype and Cd and Zn content in IP. Furthermore, significant differences were identified between A/A and A/G genotype with regard to the type of metal contaminant. The Spearman rank correlation results showed the MT2A gene expression and both Cd and Cu levels were negatively correlated. The results obtained in this study suggest that the − 5 A/G SNP in the MT2A gene may have an effect on allele-specific gene expression and toxic metal accumulation in sinonasal inverted papilloma. - Highlights: • MT2A gene expression and metal content in sinonasal inverted papilloma tissues • Association between SNP (rs28366003) and expression of MT2A • Significant

    AIM: To evaluate the causes and the relative factors of recurrent acute pancreatitis.METHODS: From 1997 to 2000, acute pancreatitis relapsed in 77 of 245 acute pancreatitis patients. By reviewing the clinical treatment results and the follow-up data, we analyzed the recurrent factors of acute pancreatitis using univariate analysis and multivariate analysis.RESULTS: Of the 245 acute pancreatitis patients, 77 were patients with recurrent acute pancreatitis. Of them, 56 patients relapsed two times, 19 relapsed three times, each patient relapsed three and four times. Forty-seven patients relapsed in hospital and the other 30 patients relapsed after discharge. Eighteen patients relapsed in 1 year, eight relapsed in 1-3 years, and four relapsed after 3 years. There were 48 cases of biliary pancreatitis, 3 of alcohol pancreatitis, 5 of hyperlipidemia pancreatitis, 21 of idiopathic pancreatitis. Univariate analysis showed that the patients with local complications of pancreas, obstructive jaundice and hepatic function injury were easy to recur during the treatment period of acute pancreatitis (P = 0.022<0.05, P = 0.012<0.05 and P = 0.002<0.05, respectively). Multivariate analysis showed that there was no single factor related to recurrence. Of the 47 patients who had recurrence in hospital, 16 had recurrence in a fast period, 31 after refeeding. CONCLUSION: Acute pancreatitis is easy to recur even during treatment. The factors such as changes of pancreas structure and uncontrolled systemic inflammatory reaction are responsible for the recurrence of acute pancreatitis. Early refeeding increases the recurrence of acute pancreatitis. Defining the etiology is essential for reducing the recurrence of acute pancreatitis.

  9. Percutaneous needle fasciotomy for recurrent Dupuytren disease.

    2012-09-01

    Increasing options to treat Dupuytren disease include percutaneous needle fasciotomy (PNF), a minimally invasive technique that has proven to be effective for the treatment of primary disease. However, its effect on recurrent disease is not clear. We studied 30 patients with recurrent Dupuytren disease in 40 fingers, with a mean follow-up of 4.4 years. Primary outcome measures were total passive extension deficit reduction and interval to a second recurrence, defined as an increase of more than 30° compared with the result at the end of the previous treatment. We noted complications. Total passive extension reduction was 76%. Percutaneous needle fasciotomy was especially effective for the metacarpophalangeal joint, with an average reduction of 93%, whereas the average reduction in the proximal interphalangeal joint was 57%. A total of 50% of patients did not develop a secondary recurrence during follow-up. The other 50% did, and we treated recurrence within an average of 1.4 years after PNF. By means of PNF, we postponed tertiary treatment an average of 2.9 years starting from the initial treatment for Dupuytren disease. We successfully treated all secondary recurrences by limited fasciectomy, according to patients' wishes. We noted no major adverse effects. Percutaneous needle fasciotomy can be applied effectively for recurrent disease; 50% of patients remain free of recurrence for a mean of 4.4 years. If a secondary recurrence occurs, it does so relatively early after treatment. Patients must therefore be willing to accept this uncertainty in the context of the advantages of PNF, such as fast recovery, low complication rate, and minimal invasiveness.

    Full Text Available Epigastric heteropagus (EH refers to asymmetrically conjoined twins in whom an incomplete parasite is attached to the autosite's epigastric region from the xiphisternum to the umbilicus. We herein report an extremely rare case of EH in which unexpected rapid recurrence occurred 22 months after excision of the parasite. The recurrent mass comprised the intestinal wall with peristalsis-like movement, urogenital tissues, and hepatic tissue of the parasite. The recurrence was caused by a remnant of the parasite that extended from the autosite's xiphisternum to intra-abdominal cavity.

    Full Text Available Stroke is the third leading cause of death, a major cause of disability in adults, and is frequently more disabling than fatal. With a decline in mortality from initial cerebral infarction and an increase in the life expectancy of the population, the number of patients with recurrent stroke and ensuing cardiovascular events will become greater. Thus it is important to find out those patients at high risk of stroke recurrence. This case report illustrates the process of recurrent stroke and the resulting disabilities and morbidities in a 42-year- old man. The role of integrated stroke rehabilitation programme is described.

  13. Discontinuities in recurrent neural networks.

    Gavaldá, R; Siegelmann, H T

    1999-04-01

    This article studies the computational power of various discontinuous real computational models that are based on the classical analog recurrent neural network (ARNN). This ARNN consists of finite number of neurons; each neuron computes a polynomial net function and a sigmoid-like continuous activation function. We introduce arithmetic networks as ARNN augmented with a few simple discontinuous (e.g., threshold or zero test) neurons. We argue that even with weights restricted to polynomial time computable reals, arithmetic networks are able to compute arbitrarily complex recursive functions. We identify many types of neural networks that are at least as powerful as arithmetic nets, some of which are not in fact discontinuous, but they boost other arithmetic operations in the net function (e.g., neurons that can use divisions and polynomial net functions inside sigmoid-like continuous activation functions). These arithmetic networks are equivalent to the Blum-Shub-Smale model, when the latter is restricted to a bounded number of registers. With respect to implementation on digital computers, we show that arithmetic networks with rational weights can be simulated with exponential precision, but even with polynomial-time computable real weights, arithmetic networks are not subject to any fixed precision bounds. This is in contrast with the ARNN that are known to demand precision that is linear in the computation time. When nontrivial periodic functions (e.g., fractional part, sine, tangent) are added to arithmetic networks, the resulting networks are computationally equivalent to a massively parallel machine. Thus, these highly discontinuous networks can solve the presumably intractable class of PSPACE-complete problems in polynomial time.

    2009-04-01

    Full Text Available Abstract Background The study tested the hypothesis that apoptosis can prevent and control growth of neoplastic cells. Previous studies in-vitro have shown that the pro-apoptotic P2X7 receptor regulates growth of epithelial cells. The specific objective of the present study was to understand to what degree the P2X7 system controls development and growth of skin cancer in vivo, and what cellular and molecular mechanisms are involved in the P2X7 action. Methods Skin neoplasias in mice (papillomas, followed by squamous spindle-cell carcinomas were induced by local application of DMBA/TPA. Experiments in-vitro utilized cultured epidermal keratinocytes generated from wild-type or from P2X7-null mice. Assays involved protein immunostaining and Western blots; mRNA real-time qPCR; and apoptosis (evaluated in situ by TUNEL and quantified in cultured keratinocytes as solubilized DNA or by ELISA. Changes in cytosolic calcium or in ethidium bromide influx (P2X7 pore formation were determined by confocal laser microscopy. Results (a Co-application on the skin of the P2X7 specific agonist BzATP inhibited formation of DMBA/TPA-induced skin papillomas and carcinomas. At the completion of study (week 28 the proportion of living animals with cancers in the DMBA/TPA group was 100% compared to 43% in the DMBA/TPA+BzATP group. (b In the normal skin BzATP affected mainly P2X7-receptor – expressing proliferating keratinocytes, where it augmented apoptosis without evoking inflammatory changes. (c In BzATP-treated mice the degree of apoptosis was lesser in cancer than in normal or papilloma keratinocytes. (d Levels of P2X7 receptor, protein and mRNA were 4–5 fold lower in cancer tissues than in normal mouse tissues. (e In cultured mouse keratinocytes BzATP induced apoptosis, formation of pores in the plasma membrane, and facilitated prolonged calcium influx. (f The BzATP-induced apoptosis, pore-formation and augmented calcium influx had similar dose-dependence for

    Full Text Available BACKGROUND. Little is known about human papilloma virus (HPV seroprevalence in the healthy Italian population. The aim of the study was to assess seroprevalence of antibodies against HPV 6, 11, 16 and 18 among girls and young women in Italy. METHODS. Sera were tested with a commercially available ELISA assay detecting specific IgG. Results. Seroprevalence was 54.1% in girls between 11 to 18 years old and 8.2% in over 18s. Overall seropositivity in birth cohorts invited for free immunization reached 72.8% and was significantly higher than in other age subgroups. The highest levels of antibodies were detected in girls of 12 years old that should have just completed the vaccination schedule. Conclusion. A standardized seroepidemiological survey on HPV represents a useful tool for identifying groups at risk in which immunization is recommended, monitoring of vaccinated women, assessing whether booster vaccination is required.

    Swoger, Jason M; Regueiro, Miguel

    2012-06-01

    Disease recurrence following resective surgery for Crohn disease remains a challenging clinical problem, and more studies are needed to better define risk stratification and treatment recommendations in the postoperative setting. Endoscopy remains the gold standard for the assessment of postoperative disease recurrence, and all Crohn disease patients who undergo surgery should undergo ileocolonoscopy within 6 to 12 months of surgery. The degree of endoscopic recurrence in the neoterminal ileum during this procedure provides prognostic information regarding the severity of the future disease course. WCE, MRE, and SICUS are all promising noninvasive modalities to assess for postoperative Crohn disease activity. However, further studies are needed to better define scoring systems, operating characteristics and variability, and prognostic data for each of these modalities. In patients at risk for early disease recurrence, more aggressive prophylactic therapy should be considered, in hopes of delivering true “top-down” therapy that may offer maximum impact in altering the natural history of Crohn disease.

    2008-01-01

    Whether acute recurrent pancreaUtis is a chronic disease is still debated and a consensus is not still reached as demonstrated by differences in the classification of acute recurrent pancreatitis.There is major evidence for considering alcoholic pancreatitis as a chronic disease ab initio while chronic pancreatitis lesions detectable in biliary acute recurrent pancreatitis (ARP) seem a casual association.Cystic fibrosis transmembrane con ductance regulator (CFTR) gene mutation,hereditary and obstructive pancreatitis seem an acute disease that progress to chronic pancreatitis,likely as a consequence of the activation and proliferation of pancreatic stellate cells that produce and activate collagen and therefore fibrosis.From the diagnostic point of view,in patients with acute recurrent pancreatitis Endoscopic ultrasound (EUS) seems the more reliable technique for an accurate evaluation and follow-up of some ductal and parenchymal abnormalities suspected for early chronic pancreatitis.

    Benign peritoneal cystic mesothelioma (BPCM) is a rare disease entity that arises from mesothelioma cells. We describe a rare case of BPCM recurrence 36 years after its initial presentation. A 62-year-old woman was referred to an outpatient gynaecologic oncology clinic with an incidental finding of multiple pelvic cysts. She had a preceding history of known BPCM treated with extensive debulking surgery. She presented after 36 years of clinical remission. A repeat laparotomy for a debulking surgical procedure confirmed a recurrence of BPCM. Our current case represents a woman with a remote recurrence of BPCM after initial optimal debulking surgery. Her clinical presentation of recurrence after 36 years illustrates the need for long-term follow-up and clinical suspicion in symptomatic patients with previously diagnosed BPCM.

    Full Text Available Hemangiopericytomas are vascular tumors with a susceptibility to arise anywhere in the human body. We present a case of a 68-year-old female with primary omental hemangiopericytoma and a two-time recurrence managed with surgery and close follow-up. The first recurrence was at 52 months and the second at 37 months following the prior presentation. No adjuvant chemotherapy or radiation therapy was administered. Given the widespread nature of the cell of origin, routine follow-up postoperatively with interval imaging in order to detect recurrences is imperative. Pathologic tumor characteristics may determine potential for recurrence and may also assist in determining whether adjuvant treatment modalities should be included in the management plan. Review of the English literature reveals a total of 24 cases of omental hemangiopericytomas inclusive of the current report.

    Congo African Grey Parrots (GP; Psittacus erithacus erithacus) from four different avicultures, presented in the Clinic for Exotic Pets, Reptiles and Birds, University of Veterinary Medicine Hannover, Foundation, showed choanal papillomas or hyperemia of the cloacal mucosa. Histologically, the mucosal choanal proliferations were diagnosed as exophytic papillomas and a mild hyperplasia of the cloacal mucosa with lympho-histiocytic inflammation with no visible inclusion bodies was found. Herpesvirus genome was detected by nested PCR in pooled choanal and cloacal swabs from clinically diseased parrots and healthy contact animals. Sequencing of parts of the herpesvirus DNA-polymerase gene indicated 98-100% homology of the detected herpesviruses with the Psittacid Herpesvirus 2 (PsHV-2). In one aviculture with cloacal inflammation papillomavirus-DNA was concurrently found to a PsHV-2 infection. In addition to the four avicultures with clinical symptoms 25 more flocks of grey parrots, in total 57 Congo-GP and 13 Timneh-GP, were examined for a herpesvirus infection. A total of six out of 29 studied parrot avicultures were tested positive for PsHV-2. The detection of this virus also in flocks of GP, which were bred in Europe, shows the establishment of this infection in the GP population in captivity. As indicated in the literature as well as in our study PsHV-2 could be only detected in Congo-GP, independently if they were kept either alone or in mixed avicultures with amazon and macaw species. These findings suggest that PsHV-2 is adapted to this Psittacus species.

  17. Family history and recurrence of febrile seizures.

    OpenAIRE

    1994-01-01

    To determine the value of a detailed family history for the assessment of the risk of recurrence of febrile seizures, 115 children who visited the emergency room of an academic children's hospital were studied prospectively. The recurrence risk of febrile seizures was analysed in relation to the child's family history and the proportion of relatives affected by febrile seizures using Kaplan-Meier estimates and Cox proportional hazard models. A first degree family history positive for febrile ...

    To determine the recurrence risk of ictal asystole (IA) and its determining factors in people with epilepsy. We performed a systematic review of published cases with IA in 3 databases and additionally searched our local database for patients with multiple seizures simultaneously recorded with ECG and EEG and at least one IA. IA recurrence risk was estimated by including all seizures without knowledge of the chronological order. Various clinical features were assessed by an individual patient data meta-analysis. A random mixed effect logistic regression model was applied to estimate the average recurrence risk of IA. Plausibility of the calculated IA recurrence risk was checked by analyzing the local dataset with available information in chronological order. Eighty patients with 182 IA in 537 seizures were included. Recurrence risk of IA amounted to 40% (95% confidence interval [CI] 32%-50%). None of the clinical factors (age, sex, type and duration of epilepsy, hemispheric lateralization, duration of IA per patient) appeared to have a significant effect on the short-term recurrence risk of IA. When considering the local dataset only, IA recurrence risk was estimated to 30% (95% CI 14%-53%). Information whether IA coincided with symptoms (i.e., syncope) or not was given in 60 patients: 100 out of 142 IAs were symptomatic. Our data suggest that in case of clinically suspected IA, the recording of 1 or 2 seizures is not sufficient to rule out IA. Furthermore, the high short-term recurrence risk favors aggressive treatment, including pacemaker implantation if seizure freedom cannot be achieved. Copyright © 2017 The Author(s).

  19. Laboratory constraints on models of earthquake recurrence

    In this study, rock friction ‘stick-slip’ experiments are used to develop constraints on models of earthquake recurrence. Constant-rate loading of bare rock surfaces in high quality experiments produces stick-slip recurrence that is periodic at least to second order. When the loading rate is varied, recurrence is approximately inversely proportional to loading rate. These laboratory events initiate due to a slip rate-dependent process that also determines the size of the stress drop [Dieterich, 1979; Ruina, 1983] and as a consequence, stress drop varies weakly but systematically with loading rate [e.g., Gu and Wong, 1991; Karner and Marone, 2000; McLaskey et al., 2012]. This is especially evident in experiments where the loading rate is changed by orders of magnitude, as is thought to be the loading condition of naturally occurring, small repeating earthquakes driven by afterslip, or low-frequency earthquakes loaded by episodic slip. As follows from the previous studies referred to above, experimentally observed stress drops are well described by a logarithmic dependence on recurrence interval that can be cast as a non-linear slip-predictable model. The fault’s rate dependence of strength is the key physical parameter. Additionally, even at constant loading rate the most reproducible laboratory recurrence is not exactly periodic, unlike existing friction recurrence models. We present example laboratory catalogs that document the variance and show that in large catalogs, even at constant loading rate, stress drop and recurrence co-vary systematically. The origin of this covariance is largely consistent with variability of the dependence of fault strength on slip rate. Laboratory catalogs show aspects of both slip and time predictability and successive stress drops are strongly correlated indicating a ‘memory’ of prior slip history that extends over at least one recurrence cycle.

    2000-01-01

    Recurrence formulae for arbitrary hydrogenic radial matrix elements are obtained in the Dirac form of relativistic quantum mechanics. Our approach is inspired on the relativistic extension of the second hypervirial method that has been succesfully employed to deduce an analogous relationship in non relativistic quantum mechanics. We obtain first the relativistic extension of the second hypervirial and then the relativistic recurrence relation. Furthermore, we use such relation to deduce relativistic versions of the Pasternack-Sternheimer rule and of the virial theorem.

    The aim of this study was to determine a definition of recurrence of Dupuytren disease that could be utilized for the comparison of the results independently from the treatment used. 24 hand surgeons from 17 countries met in an international consensus conference. The participants used the Delphi method to evaluate a series of statements: (1) the need for defining recurrence, (2) the concept of recurrence applied to the Tubiana staging system, (3) the concept of recurrence applied to each single treated joint, and (4) the concept of recurrence applied to the finger ray. For each item, the possible answer was given on a scale of 1-5: 1=maximum disagreement; 2=disagreement; 3=agreement; 4=strong agreement; 5=absolute agreement. There was consensus on disagreement if 1 and 2 comprised at least 66% of the recorded answers and consensus on agreement if 3, 4 and 5 comprised at least 66% of the recorded answers. If a threshold of 66% was not reached, the related statement was considered "not defined". A need for a definition of recurrence was established. The presence of nodules or cords without finger contracture was not considered an indication of recurrence. The Tubiana staging system was considered inappropriate for reporting recurrence. Recurrence was best determined by the measurement of a specific joint, rather than a total ray. Time 0 occurred between 6 weeks and 3 months. Recurrence was defined as a PED of more than 20° for at least one of treated joint, in the presence of a palpable cord, compared to the result obtained at time 0. This study determined the need for a standard definition of recurrence and reached consensus on that definition, which we should become the standard for the reporting of recurrence. If utilized in subsequent publications, this will allow surgeons to compare different techniques and make is easier to help patients make an informed choice.

  2. FSGS Recurrence in Adults after Renal Transplantation

    2016-01-01

    Full Text Available Recurrence of focal segmental glomerulosclerosis (FSGS in the allograft occurs in 30–50% of patients, and it is associated with poor renal allograft survival. Major risk factors for recurrence are younger age at diagnosis, rapid progression to end-stage renal disease, white race, and the loss of previous allografts due to recurrence. Recent data support the hypothesis that circulating permeability factors play a crucial role in podocyte injury and progression of FSGS. Due to lack of controlled trials, the management of recurrent FSGS is inconsistent and highly empirical. Prophylactic and perioperative treatment with plasmapheresis and high-dose (intravenous cyclosporine represent the main cornerstones of immunosuppressive therapy. In recent years, therapy with rituximab has shown promising results. Despite evidence of activation of the renin-angiotensin system (RAS in recurrent FSGS and its association with progression, only limited data exist on the renoprotective role of RAS blockade in this setting. Further well designed studies are needed on pathogenesis risk factors and therapeutical options in FSGS and its recurrence after transplantation.

    2010-06-01

    We study the statistical properties of the recurrence intervals τ between successive trading volumes exceeding a certain threshold q. The recurrence interval analysis is carried out for the 20 liquid Chinese stocks covering a period from January 2000 to May 2009, and two Chinese indices from January 2003 to April 2009. Similar to the recurrence interval distribution of the price returns, the tail of the recurrence interval distribution of the trading volumes follows a power-law scaling, and the results are verified by the goodness-of-fit tests using the Kolmogorov-Smirnov (KS) statistic, the weighted KS statistic and the Cramér-von Mises criterion. The measurements of the conditional probability distribution and the detrended fluctuation function show that both short-term and long-term memory effects exist in the recurrence intervals between trading volumes. We further study the relationship between trading volumes and price returns based on the recurrence interval analysis method. It is found that large trading volumes are more likely to occur following large price returns, and the comovement between trading volumes and price returns is more pronounced for large trading volumes.

    Recurrence of cancer in the breast is an important problem in breast-conserving therapy. We evaluated risk factors for recurrence from the viewpoint of recurrence type and outcome after recurrence. Of 533 cases of breast cancer treated with breast-conserving surgery from April 1989 through July 2000, disease in 66 recurred (12.4%) and were classified as 23 cases of breast recurrence only, 16 cases of both breast recurrence and distant metastasis, and 27 cases of distant metastasis only. The clinical factors examined included age, lymphatic invasion, nodal status, extensive intraductal component (EIC), proliferative activity, and estrogen receptor (ER) status. Of the 39 cases of breast recurrence, 19 had intramammary tumors and 20 had extramammary tumors of the skin, subcutaneous tissue, or muscle, including 8 cases with inflammatory breast recurrence. Multivariate analysis showed that factors correlated with breast recurrence were age, ER status, proliferative activity, and surgical margin. EIC-comedo was related to intramammary recurrence, whereas lymphatic invasion and nodal status were related to extramammary recurrence. Postoperative irradiation was an effective treatment for tumors in young women and tumors with positive margins or a comedo component. Outcome after breast recurrence depended on nodal status at primary operation, and survival rates were worst in patients with inflammatory breast recurrence. In conclusion, age, EIC-comedo status, the surgical margin, and negative ER status were correlated with breast recurrence. Countermeasures against these factors should be investigated. (author)

    Full Text Available Background:Febrile Convulsion is the most common convulsive disorder in children,occurring in 2 to 4% of the pediatric population and recurring in 30-50% of cases. Considering the varying recurrence rates reported, thisstudy was conducted at the pediatric ward of the Shaheed BeheshtiGeneral Hospital, between 2000-2001 to determine the frequencyof recurrence and related risk factors in children presenting with theirfirst episode of febrile convulsionMaterials & Methods:A two–year cohort study was performed on 50 children presentingwith the first attack of febrile convulsion. Patient demographic dataincluding age, sex, type and duration of seizure, family history offebrile seizure or epilepsy and the interval between fever onset andoccurrence of seizure were recorded in questionnaires. Those patients,for whom prophylactic medication was not administered, werefollowed at three–month intervals for up to one year. Findings werestatistically analyzed using Fisher’s exact testResults:Recurrence was observed in twelve children (24% out of the fifty,being most common in patients aged less than one year (54.4%.Recurrence rates among children with a positive family history offebrile convulsion, presence of complex febrile seizure and positivefamily history of epilepsy were 42.1%, 42.8% and 25% respectively.From among those children with a “less than one hour” intervalbetween fever onset and occurrence of seizure, recurrence occurredin 43-7% of cases, while in those with a “more than one hourinterval”, 14.7% experienced recurrence.Conclusion:Recurrence rates are increased by certain factors including age-belowone year-, positive family history of febrile convulsion, and a “lessthan one hour” interval between time of fever onset and seizureoccurrence.

    Recurrence-plot-based recurrence networks are an approach used to analyze time series using a complex networks theory. In both approaches - recurrence plots and recurrence networks -, a threshold to identify recurrent states is required. The selection of the threshold is important in order to avoid bias of the recurrence network results. In this paper, we propose a novel method to choose a recurrence threshold adaptively. We show a comparison between the constant threshold and adaptive threshold cases to study period-chaos and even period-period transitions in the dynamics of a prototypical model system. This novel method is then used to identify climate transitions from a lake sediment record.

    The pattern of recurrence affects the clinical outcome in tumor patients. However, the clinical significance of lung metastasis as the primary recurrence site after resection in patients with pancreatic cancer remains unclear. This study aimed to clarify the clinical significance of the primary recurrence site in patients with pancreatic cancer, in terms of prognosis and clinicopathological features. This retrospective cohort study included 220 patients with postoperative recurrence after pancreatectomy for pancreatic cancer and classified by primary site of recurrence. We focused on patients with lung metastasis as the primary recurrence and investigated its correlation with prognosis and clinicopathological factors. Twenty-four (11%) patients had lung metastasis as the primary recurrence. This recurrence pattern had the best prognosis among all recurrence patterns, including liver metastasis and local recurrence. Patients with lung metastasis as the primary recurrence had favorable overall survival and survival from the date of recurrence compared with patients with other primary recurrence sites in both univariate (P = 0.0008 and P = 0.0005) and multivariate analyses (P = 0.0051 and P = 0.0068). In terms of clinicopathological features of resected pancreatic tumors, lung metastasis as the primary recurrence was associated with lower tumor stage and histologic grade, and less vascular invasion and residual tumor volume than liver metastasis. Pancreatic cancer patients with lung metastasis as the primary recurrence after pancreatectomy have a better prognosis than those with other recurrence patterns.

    Surgery for recurrent pleomorphic adenoma (PA) can be challenging and may increase the risk of operative complications, particularly facial nerve weakness. As observation may be a viable alternative to surgery for slow-growing tumors, our objective was to assess the growth rate of recurrent PAs. This study is a case series of patients at our tertiary academic medical center with recurrent PA. Two magnetic resonance images (MRI) were compared; total volume (TV) of recurrent tumor on both studies was calculated to obtain our main outcomes of percent change in TV and tumor growth rate. Fourteen patients with recurrent PA had a median interval time between MRI of 12.8 months. Though growth rates were variable, the median continuous compound growth per year was 10.2%. Notably, 3 patients (21%) had no growth, and 2 patients (14%) had a reduction in TV. The median growth rate for enlarging tumors is estimated at 10.2% per year. Due to variability, tumor growth rate should be estimated on an individual patient basis. For slow-growing tumors, physicians may weigh the risk of this slow growth with the morbidity of reoperation.

  12. Management of postoperative recurrence of Crohn's disease.

    2013-01-01

    The course of Crohn's disease (CD) is unpredictable and potentially destructive. The percentage of patients requiring surgery at some stage in their disease accumulates to over 70%. After resection of the affected intestine, reappearance of CD occurs in the majority of patients. Prophylactic medical therapy to reduce the rate of postoperative recurrence has been proven to be effective, yet the incidence of recurrence remains high. Patient profiling (risk stratification) is important in this postoperative setting. High-risk patients (associated with e.g. smoking, the need of repetitive surgery and penetrating disease) require strong immunosuppressive treatment, which should be commenced immediately after surgery, when recurrent disease activity begins. Additionally, early screening endoscopy should be performed to monitor treatment effect. The efficacy of thiopurines is shown to be higher than mesalazine or imidazole antibiotics alone for preventing and ameliorating endoscopic recurrence of CD postoperatively; however, anti-tumor necrosis factors (anti-TNFs) are increasingly considered the most potent agents. In patients with a risk factor for early postoperative recurrence, the first line of treatment is 6-mercaptopurine, in combination with imidazole antibiotics if tolerated, followed by anti-TNFs. When lesions are found at colonoscopy, therapy should be upscaled. We propose a treatment algorithm to direct therapeutic management of CD postoperatively. © 2013 S. Karger AG, Basel.

    To compare azithromycin (AZT) and benzathine penicillin (BP) in the treatment of recurrent tonsillitis in children. The study comprised of 350 children with recurrent streptococcal tonsillitis, 284 of whom completed the study and 162 children received conventional surgical treatment. The rest of the children, 122, were divided randomly into two equal main groups. Group A children received a single intramuscular BP (600,000IU for children≤27kg and 1,200,000IU for ≥27kg) every two weeks for six months. Group B children received single oral AZT (250mg for children≤25kg and 500mg for ≥25kg) once weekly for six months. Both groups showed marked significant reduction in recurrent tonsillitis that is comparable to results of tonsillectomy. There were no statistical differences between group A and B regarding the recurrence of infections and drug safety after six-month follow-up. Group B showed better compliance. AZT proved to be good alternative to BP in the management of recurrent tonsillitis with results similar to those obtained after tonsillectomy. Copyright © 2017 Elsevier Inc. All rights reserved.

    Recurrence of H pylori after eradication is rare in developed countries and more frequent in developing countries.Recrudescence(recolonization of the same strain within 12 mo after eradication)rather than reinfection(colonization with a new strain,more than 12 mo after eradication)is considered to be responsiblefor most of the cases.This observation was confirmed only in developed countries,while in developing countries a recent meta-analysis demonstrated a high rate of reinfection.The proportion of H pylori annual recurrence was 2.67% and 13.00% in developed and developing countries,respectively.Nested meta-analysis(only cases with a longer follow-up and a negative 13CUBT a year after eradication)revealed annual recurrence rate of 1.45%[relative risk(RR),0.54]and 12.00%(RR,0.92)in developed and developing countries,respectively.These findings support the notion that in developed countries many cases of recurrence are due to recrudescence within the first year after eradication,with a 46% drop in the recurrence rate after the first year post eradication,while in developing countries reinfection is more pronounced,and continue at the same rate since eradication.A different approach for follow-up after H pylori eradication is probably needed in patients of developing countries,since reinfection is highly prevalent.

    Bronchioloalveolar carcinoma is a distinctive subtype of typical adenocarcinoma of the lung that tends to metastasize widely throughout the lungs but less commonly elsewhere. Because conventional therapies for intrapulmonary metastatic bronchioloalveolar carcinoma are generally ineffective, we treated seven patients who had intrapulmonary metastatic bronchioloalveolar carcinoma with lung transplantation. Seven patients with biopsy-proved bronchioloalveolar carcinoma and no evidence of extrapulmonary disease received transplants of either one or two cadaveric lungs. At transplantation, all native lung tissue was removed and replaced with a donor lung or lungs. The patients received the usual post-transplantation care given at the institution. Four of the seven patients had recurrent bronchioloalveolar carcinoma within the donor lungs; the recurrences appeared from 10 to 48 months after transplantation. All recurrences were limited to the donor lungs. Histologic and molecular analyses showed that the recurrent tumors in three patients originated from the recipients of the transplants. Lung transplantation for bronchioloalveolar carcinoma is technically feasible, but recurrence of the original tumor within the donor lungs up to four years after transplantation was common.

    In recent years, group G Streptococcus has been reported with increasing frequency as the cause of a variety of human infections. Underlying host factors such as immunosuppression, malignancy, diabetes mellitus, and rheumatoid arthritis may be predisposing conditions leading to infection. Toxic involvement and post-streptococcal sequalae, once believed to be exclusive to infections caused by group A Streptococcus, are now known to occur following acute group G Streptococcus and group C Streptococcus infections. We report on a case of group G Streptococcus bacteremia and recurrent cellulitis with toxic involvement. Patient blood cultures were always negative for β-hemolytic Streptococci in all the recurrences, except during the last one. Antibiotic therapy based on antibiogram quickly resolved the infection. A regimen of intramuscular injection of 1.2 million units of benzathine penicillin every 15 days for one year prevented recurrences of cellulitis.

    Full Text Available In spite of the recent improvements in drug therapy, surgery still represents the most frequent treatment for Crohn's disease (CD complications. Laparoscopy has been widely applied over the last twenty years in colorectal surgery and was associated with lower postoperative pain, shorter hospitalization, faster return to daily activities, and better cosmetic results. Laparoscopy experienced a slower diffusion in inflammatory bowel disease surgery than in oncologic colorectal surgery, but proved to be safe and effective, and is currently considered the gold standard for the treatment of primary uncomplicated ileocolic CD. Indications for laparoscopy in CD have recently been widened to embrace more complicated or recurrent CD. This paper reviews the available data on the subset of recurrent CD patients. The reported results indicate that laparoscopy may be safely applied even in selected recurrent CD cases in hands of IBD surgeons with broad laparoscopic experience.

In these solutions, the light cone, flips periodically between past and future, due to a periodically alternating arrow of the proper time. The geodesics in these universes show periodic Loschmidt's velocity reversion $v \\to -v$, at critical points, which leads to recurrence. However, the matter tensors of some of these solutions exhibit unusual properties - such as, periodic variations in density and pressure. While this is to be expected in periodic models, the physical basis for such a variation is not clear. Present paper therefore can be regarded as an extension of Tipler's "no go theorem for recurrence in an expanding universe", to other space-time geometries.

    Spinal intramedullary epidermoid cyst is a rare condition. Recurrent epidermoid cyst in the spine cord is known to occur. The authors describe a case of recurrent conus medullaris epidermoid cyst in a 24-year-old female. She initially presented at 7 years of age with bladder disturbance in the form of diurnal enuresis and recurrent urinary tract infection. MRI lumbar spine revealed a 4 cm conus medullaris epidermoid cyst. Since the initial presentation, the cyst had recurred seven times in the same location and she underwent surgical intervention in the form of exploration and debulking. This benign condition, owing to its anatomical location, has posed a surgical and overall management challenge. This occurrence is better managed in a tertiary-care centre requiring multi-disciplinary treatment approach.
