    Abstract Actinomycosis is a rare heterogeneous anaerobic infection with misleading clinical presentations that delay diagnosis. A significant number of misdiagnosed cases have been reported in specific localizations, but studies including various forms of actinomycosis have rarely been published. We performed a multicenter retrospective chart review of laboratory-confirmed actinomycosis cases from January 2000 until January 2014. We described clinical characteristics, diagnostic procedures, differential diagnosis, and management of actinomycosis of clinical significance. Twenty-eight patients were included from 6 hospitals in France. Disease was diagnosed predominately in the abdomen/pelvis (n = 9), orocervicofacial (n = 5), cardiothoracic (n = 5), skeletal (n = 3), hematogenous (n = 3), soft tissue (n = 2), and intracranially (n = 1). Four patients (14%) were immunocompromised. In most cases (92 %), the diagnosis of actinomycosis was not suspected on admission, as clinical features were not specific. Diagnosis was obtained from either microbiology (50%, n = 14) or histopathology (42%, n = 12), or from both methods (7%, n = 2). Surgical biopsy was needed for definite diagnosis in 71% of cases (n = 20). Coinfection was found in 13 patients (46%), among which 3 patients were diagnosed from histologic criteria only. Two-thirds of patients were treated with amoxicillin. Median duration of antibiotics was 120 days (interquartile range 60–180), whereas the median follow-up time was 12 months (interquartile range 5.25–18). Two patients died. This study highlights the distinct and miscellaneous patterns of actinomycosis to prompt accurate diagnosis and earlier treatments, thus improving the outcome. Surgical biopsy should be performed when possible while raising histologist's and microbiologist's awareness of possible actinomycosis to enhance the chance of diagnosis and use specific molecular methods.

    Crick, Murray-Close, and Woods (2005) encouraged the study of relational aggression as a developmental precursor to borderline personality features in children and adolescents. A longitudinal study is needed to more fully explore this association, to contrast potential associations with physical aggression, and to assess generalizability across various cultural contexts. In addition, parenting is of particular interest in the prediction of aggression or borderline personality disorder. Early aggression and parenting experiences may differ in their long-term prediction of aggression or borderline features, which may have important implications for early intervention. The currrent study incorporated a longitudinal sample of preschool children (84 boys, 84 girls) living in intact, two-parent biological households in Voronezh, Russia. Teachers provided ratings of children's relational and physical aggression in preschool. Mothers and fathers also self-reported their engagement in authoritative, authoritarian, permissive, and psychological controlling forms of parenting with their preschooler. A decade later, 70.8% of the original child participants consented to a follow-up study in which they completed self-reports of relational and physical aggression and borderline personality features. The multivariate results of this study showed that preschool relational aggression in girls predicted adolescent relational aggression. Preschool aversive parenting (i.e., authoritarian, permissive, and psychologically controlling forms) significantly predicted aggression and borderline features in adolescent females. For adolescent males, preschool authoritative parenting served as a protective factor against aggression and borderline features, whereas authoritarian parenting was a risk factor for later aggression.

    The vector for dengue fever and chikungunya, Aedes albopictus, was recently identified in Southeastern France, although the usual vector for dengue fever is Aedes aegypti, raising the possibility of cases occurring among the local population via viraemic individuals returning from endemic areas. Dengue fever is usually transmitted by Aedes aegypti. It is due to an arbovirus-flavivirus of which four different serotypes are known: Den 1 to 4. Each serotype is responsible for specific prolonged immunity but no cross-reactivity exists between serotypes. Clinically, the onset is abrupt with frontal headache, retro-orbital pain, myalgia, joint pain, prostration and, in many cases, a macular rash usually sparing the face and extremities. Haemorrhagic signs may occur, such as petechiae, purpura, epistaxis or bleeding gingivae. Two severe forms of dengue fever, particularly among children below 3 years of age, include dengue haemorrhagic fever (DHF) and DHF with shock (dengue shock syndrome). If a case is suspected in metropolitan France, the diagnosis should be systematically confirmed by positive specific IgM, RT-PCR or viral isolation. Treatment of dengue fever, whether in its uncomplicated form or with hemorrhagic manifestations or shock, remains symptomatic. There is no specific anti-viral treatment. A case should be notified to allow French health authorities to take the appropriate measures for vector control.

    Factors contributing to aggressive behavior in vulvar squamous cell carcinoma (vSCC) are poorly defined; however, a recent study has shown that vSCCs with an infiltrative pattern of invasion and fibromyxoid stroma are associated with worse outcomes than tumors with a pushing or nested pattern of invasion and lymphoplasmacytic stroma. Epithelial-mesenchymal transition (EMT) has been associated with tumor progression in a number of malignancies, and this study proposes that EMT contributes to tumor aggressiveness in this subset of vSCC. Immunohistochemistry was used to detect nuclear localization of β-catenin, loss of E-cadherin, and presence of vimentin in 58 cases of vSCC. The association of these phenotypic changes with pathologic features and clinical outcomes was tested using Fisher's exact and χ(2) analyses (significance at P≤.05). EMT-associated features were identified in 45 of 58 cases (78%) with 28 cases exhibiting more than one feature. Nuclear β-catenin and presence of vimentin were significantly more likely to occur in tumors with an infiltrative pattern of invasion or a fibromyxoid stromal response. Loss of E-cadherin was significantly associated with an infiltrative pattern, but not a fibromyxoid stroma. Risk for tumor recurrence was significantly increased in tumors with nuclear localization of β-catenin alone or in tumors displaying multiple EMT-associated features. These results suggest that the development of EMT may be a mechanism by which infiltrative vulvar tumors with a fibromyxoid stromal response behave more aggressively and convey worse outcomes than tumors that do not exhibit these pathologic features.

    Systemic mastocytosis (SM) is a rare myeloproliferative disease without curative therapy. Despite clinical variability, the majority of patients harbour a KIT-D816V mutation, but efforts to inhibit mutant KIT with tyrosine kinase inhibitors have been unsatisfactory, indicating a need for new preclinical approaches to identify alternative targets and novel therapies in this disease. Murine models to date have been limited and do not fully recapitulate the most aggressive forms of SM. We describe the generation of a transgenic zebrafish model expressing the human KIT-D816V mutation. Adult fish demonstrate a myeloproliferative disease phenotype, including features of aggressive SM in haematopoeitic tissues and high expression levels of endopeptidases, consistent with SM patients. Transgenic embryos demonstrate a cell-cycle phenotype with corresponding expression changes in genes associated with DNA maintenance and repair, such as reduced dnmt1. In addition, epcam was consistently downregulated in both transgenic adults and embryos. Decreased embryonic epcam expression was associated with reduced neuromast numbers, providing a robust in vivo phenotypic readout for chemical screening in KIT-D816V-induced disease. This study represents the first zebrafish model of a mast cell disease with an aggressive adult phenotype and embryonic markers that could be exploited to screen for novel agents in SM.

  9. Uterine sarcomas: clinical presentation and MRI features

    2015-01-01

    Uterine sarcomas are a rare heterogeneous group of tumors of mesenchymal origin, accounting for approximately 8% of uterine malignancies. They comprise leiomyosarcoma, endometrial stromal sarcoma, undifferentiated endometrial sarcoma, and adenosarcoma. Compared with the more common endometrial carcinomas, uterine sarcomas behave more aggressively and are associated with a poorer prognosis. Due to their distinct clinical and biological behavior, the International Federation of Gynecology and Obstetrics introduced a new staging system for uterine sarcomas in 2009, categorizing uterine carcinosarcoma as a variant of endometrial carcinoma, rather than a pure sarcoma. Magnetic resonance imaging (MRI) has a developing role in the assessment of these malignancies. Features such as tumor localization, irregular or nodular margins, necrosis, rapid growth, intense contrast enhancement, and restriction at diffusion-weighted imaging can suggest the diagnosis and help differentiate from more common leiomyomas and endometrial carcinoma. MRI is therefore extremely useful in preoperative detection and staging and, consequently, in determination of appropriate management. This pictorial review aims to discuss the clinical features of uterine sarcomas, as well as their most common appearances and distinct characteristics in MRI. PMID:25347940

    Aggression and violence are widespread in UK Mental Health Trusts, and are accompanied by negative psychological and physiological consequences for both staff and other patients. Patients who are younger, male, and have a history of substance use and psychosis diagnoses are more likely to display aggression; however, patient factors are not solely responsible for violence, and there are complex circumstances that lead to aggression. Indeed, patient-staff interactions lead to a sizeable portion of aggression and violence on inpatient units, thus they cannot be viewed without considering other forms of conflict and containment that occur before, during, and after the aggressive incident. For this reason, we examined sequences of aggressive incidents in conjunction with other conflict and containment methods used to explore whether there were particular profiles to aggressive incidents. In the present study, 522 adult psychiatric inpatients from 84 acute wards were recruited, and there were 1422 incidents of aggression (verbal, physical against objects, and physical). Cluster analysis revealed that aggressive incident sequences could be classified into four separate groups: solo aggression, aggression-rule breaking, aggression-medication, and aggression-containment. Contrary to our expectations, we did not find physical aggression dominant in the aggression-containment cluster, and while verbal aggression occurred primarily in solo aggression, physical aggression also occurred here. This indicates that the management of aggression is variable, and although some patient factors are linked with different clusters, these do not entirely explain the variation.

    With the rapid growth of clinical data and knowledge, feature construction for clinical analysis becomes increasingly important and challenging. Given a clinical dataset with up to hundreds or thousands of columns, the traditional manual feature construction process is usually too labour intensive to generate a full spectrum of features with potential values. As a result, advanced large-scale data analysis technologies, such as feature selection for predictive modelling, cannot be fully utilized for clinical data analysis. In this paper, we propose an automatic feature construction framework for clinical data analysis, namely, Feature++. It leverages available public knowledge to understand the semantics of the clinical data, and is able to integrate external data sources to automatically construct new features based on predefined rules and clinical knowledge. We demonstrate the effectiveness of Feature++ in a typical predictive modelling use case with a public clinical dataset, and the results suggest that the proposed approach is able to fulfil typical feature construction tasks with minimal dataset specific configurations, so that more accurate models can be obtained from various clinical datasets in a more efficient way.

    Introduction Surface osteosarcoma are rare variant of osteosarcoma that include parosteal osteosarcoma, periosteal osteosarcoma and high grade surface osteosarcoma. These lesions have different clinical presentation and biological behavior compared to conventional osteosarcoma, and hence need to be managed differently. Goal The aim of this study is to analyze the clinico-pathological features and outcome of a series of surface osteosarcoma in an attempt to define the adequate treatment of this rare entity. Patient and method It is a retrospective and bicentric study of 18 surface osteosarcoma that were seen at the KASSAB’s Institute and SAHLOUL Hospital from 2006 to 2013. The authors reviewed the clinical and radiologic features, histologic sections, treatments, and outcomes in this group of patients. Results Seven patients were male (38.9%) and 11 were female (61.1%) with mean age of 25 years (range from 16 to 55 years). Eleven lesions were in the femur and 7 in the tibia. We identified 11 parosteal osteosarcoma (six of them were dedifferentiated), 3 periosteal osteosarcoma and 4 high grade surface osteosarcoma. Six patients had neoadjuvant chemotherapy and all lesions had surgical resection. Margins were wide in 15 cases and intra lesional in 3 cases. Histological response to chemotherapy was poor in all cases. The mean follow up was 34.5 months. Six patients (33.3%) presented local recurrence and 8 patients (44.4%) presented lung metastases. Six patients (33.3%) died from the disease after a mean follow up of 12 months (6–30 months); all of them had high grade lesions. Conclusion Histological grade of malignancy is the main point to assess in surface osteosarcoma since it determines treatment and prognosis. Low grade lesions should be treated by wide resection, while high grade lesions need more aggressive surgical approach associated to post operative chemotherapy. PMID:26730360

    Aggressiveness attributed to violent video game play is typically studied as a function of the content features of the game. However, can interface features of the game also affect aggression? Guided by the General Aggression Model (GAM), we examine the controller type (gun replica vs. mouse) and screen size (large vs. small) as key technological aspects that may affect the state aggression of gamers, with spatial presence and arousal as potential mediators. Results from a between-subjects experiment showed that a realistic controller and a large screen display induced greater aggression, presence, and arousal than a conventional mouse and a small screen display, respectively, and confirmed that trait aggression was a significant predictor of gamers' state aggression. Contrary to GAM, however, arousal showed no effects on aggression; instead, presence emerged as a significant mediator.

    The clinical features of a group of 30 patients with recalcitrant recurrent corneal erosions (i.e. those who failed to respond to conventional therapy) were evaluated. Associated ocular and facial abnormalities were documented. Meibomian gland dysfunction was present in all patients as manifest by dropout and inspissation of the meibomian glands, reduced tear film break-up time and debris in the tear film. Dropout of meibomian glands was present in 25 (83%) patients and was maximum in the medial half of the lid in 21 (84%) of these 25 patients. Tear film break-up time was reduced in all patients, being instant in 7 (23%), between 1 and 5 seconds in 22 (74%) and between 10 and 15 seconds in 1 (3%) patient. Superficial corneal abnormalities were present in 28 (93%) patients as manifest by maps, dots and fingerprints. Facial abnormalities such as telangiectasia, rhinophyma and acne rosacea were present in 22 (73%) patients. The findings of our study suggest an association between recalcitrant recurrent corneal erosions and meibomian gland dysfunction.

    Interpersonal dysfunction and aggression are features that are frequently found in individuals with borderline personality disorder (BPD); however, few studies have examined the possible causal relationship between aggressive actions and interpersonal problems. In a nonclinical sample of 98 women with a range of BPD features, the present study examined the prospective relationship between aggressive behaviors and negative interpersonal events using a weekly diary method. Results showed that higher BPD symptoms were related to higher aggression and more negative interpersonal events. Furthermore, the aggressive acts endorsed among women with more BPD features were more likely the effect, rather than the cause, of the negative interpersonal events they experienced. Implications for interventions targeting aggression among women with elevated BPD features and suggestions for future research are discussed.

    To explore contrast (C) and homogeneity (H) gray-level co-occurrence matrix texture features on T2-weighted (T2w) Magnetic Resonance (MR) images and apparent diffusion coefficient (ADC) maps for predicting prostate cancer (PCa) aggressiveness, and to compare them with traditional ADC metrics for differentiating low- from intermediate/high-grade PCas. The local Ethics Committee approved this prospective study of 93 patients (median age, 65 years), who underwent 1.5 T multiparametric endorectal MR imaging before prostatectomy. Clinically significant (volume ≥0.5 ml) peripheral tumours were outlined on histological sections, contoured on T2w and ADC images, and their pathological Gleason Score (pGS) was recorded. C, H, and traditional ADC metrics (mean, median, 10th and 25th percentile) were calculated on the largest lesion slice, and correlated with the pGS through the Spearman correlation coefficient. The area under the receiver operating characteristic curve (AUC) assessed how parameters differentiate pGS = 6 from pGS ≥ 7. The dataset included 49 clinically significant PCas with a balanced distribution of pGS. The Spearman ρ and AUC values on ADC were: -0.489, 0.823 (mean) -0.522, 0.821 (median) -0.569, 0.854 (10th percentile) -0.556, 0.854 (25th percentile) -0.386, 0.871 (C); 0.533, 0.923 (H); while on T2w they were: -0.654, 0.945 (C); 0.645, 0.962 (H). AUC of H on ADC and T2w, and C on T2w were significantly higher than that of the mean ADC (p = 0.05). H and C calculated on T2w images outperform ADC parameters in correlating with pGS and differentiating low- from intermediate/high-risk PCas, supporting the role of T2w MR imaging in assessing PCa biological aggressiveness.

    Background Mixed adeno-neuroendocrine carcinoma (MANEC) is a rare pathologic diagnosis recently defined by the World Health Organization in 2010. Due to poor understanding of MANEC as a clinical entity, there is significant variation in the management of these patients. The purpose of our study was to characterize MANEC to develop evidence-based treatment strategies. Methods The Ohio State University patient database was queried for the diagnosis of MANEC and 46 patients were identified. For comparison, the database also was queried for goblet cell carcinoid (GCC) of the appendix, signet ring cell carcinoma, and carcinoid/neuroendocrine tumor of the appendix. Charts were then retrospectively reviewed for clinicopathologic characteristics, patient treatment, and survival data. Results The mean age of diagnosis of MANEC was 54 years. Eighty-seven percent of MANEC arose from the appendix, with 28 % of patients undergoing appendectomy and 35 % undergoing right hemicolectomy as their index operation. Immunohistochemical staining was positive for chromogranin (82 %), synaptophysin (97 %), and CD56 (67 %). Sixty-seven percent of patients presented with stage IV disease and 41 % had nodal metastases. Overall survival was 4.1 years, which was statistically significantly different (p ≤ 0.05) compared with carcinoid tumors (13.4 years), GCC (15.4 years), and signet ring carcinoma (2.2 years). Conclusions MANEC is a more aggressive clinical entity than both GCC of the appendix and carcinoid/neuroendocrine tumors of the appendix. Based on these findings, we recommend patients with MANEC tumors undergo aggressive multidisciplinary cancer management and close surveillance. PMID:26965701

    Gastroenteropancreatic (GEP) endocrine tumours (carcinoids and pancreatic islet cell tumours) are composed of multipotent neuroendocrine cells that exhibit a unique ability to produce, store, and secrete biologically active substances and cause distinct clinical syndromes. The classification of GEP tumours as functioning or non-functioning is based on the presence of symptoms that accompany these syndromes secondary to the secretion of hormones, neuropeptides and/or neurotransmitters (functioning tumours). Non-functioning tumours are considered to be neoplasms of neuroendocrine differentiation that are not associated with obvious symptoms attributed to the hypersecretion of metabolically active substances. However, a number of these tumours are either capable of producing low levels of such substances, which can be detected by immunohistochemistry but are insufficient to cause symptoms related to a clinical syndrome, or alternatively, they may secrete substances that are either metabolically inactive or inappropriately processed. In some cases, GEP tumours are not associated with the production of any hormone or neurotransmitter. Both functioning and non-functioning tumours can also produce symptoms due to mass effects compressing vital surrounding structures. Gastroenteropancreatic tumours are usually classified further according to the anatomic site of origin: foregut (including respiratory tract, thymus, stomach, duodenum, and pancreas), midgut (including small intestine, appendix, and right colon), and hindgut (including transverse colon, sigmoid, and rectum). Within these subgroups the biological and clinical characteristics of the tumours vary considerably, but this classification is still in use because a significant number of previous studies, mainly observational, have used it extensively.

    Over the past 20 or so years, a number of studies have examined patient aggression toward healthcare professionals. While the majority of these studies has focused on healthcare professionals in the fields of emergency medicine, psychiatry, and primary care, available data extends beyond these three specialties. Studies have been done in the United States, other English-speaking countries, and elsewhere— all reporting surprisingly high rates of patient aggression. Results indicate that patient aggression toward healthcare professionals is common and worldwide. In addition, one study examined aggressive patient behaviors as reported by the patients themselves, and their self-report data reinforce the mainstream data. While these data do not enable us to determine if patient aggression is genuinely on the increase, we can safely say that these behaviors are rampant. PMID:25621187

He criticized that the improper treatment by elder generations mainly was caused by their ignorance of tonifying the liver based on the saying of "no tonifying treatment for the liver". Wei Yuheng's medical theories and clinical experiences are scattered in his book Xu Mingyi Lei'an (Supplement to Classified Case Records of Celebrated Physicians). Wang Mengying collected part of his thoughts and experiences and wrote the book Liuzhou Yihua (Liuzhou Medical Talks). Although Wang Mengying's book could deduce part of the thoughts of Wei Yuheng, it didn't disclose his theories completely. It is known to all that the compound recipe Yiguan Jian is a representative formula of Wei Yuheng to tonify liver yin. Actually, it can be concluded from the analysis of Xu Mingyi Lei'an that he used Fructus Lycii (Gouqi) as a main herb to tonify liver yin in the method of nourishing yin to generate liver. Based on the idea that there are accept, restriction, generation and transformation relationship among the lung, kidney and liver yin, so he also always used Radix Glehniae (Beishashen), Radix Ophiopogonis (Maidong), Radix Rehmanniae Recens (Shengdihuang), and Radix Rehmanniae Preparata (Shudihuang) in his compound recipes. If the yin blood is insufficient, Semen Ziziphi Spinosae (Suanzaoren) should be added. In order to prepare a out way for phlegm-heat caused dy liver yin deficiency, a lubricative, Semen Trichosanthis (Gualouren) was always used and raw Semen Coicis Recens (Shengyiyiren) too. Sichuan Rhizoma Coptidis (Chuanhuanglian) can be used to clear fire-heat, and Fructus Meliae Toosendan (Chuanlianzi) for pain caused by fire-heat. PMID:17096983

  6. Gastroesophageal reflux disease: clinical features.

    PubMed

    Pettit, Michael

    2005-12-01

    Gastroesophageal reflux disease (GERD) is a chronic disease affecting up to 40% of people in the Western world. Risk factors associated with GERD include age and lifestyle habits, although the clinically relevant contribution of many of these factors is unclear. In GERD, refluxed gastric acid damages the oesophageal mucosa, generally when the pH falls below 4. GERD patients present a variety of symptoms, most commonly heartburn and regurgitation. Oesophageal complications associated with GERD include erosions, ulcers, peptic strictures, and Barrett's oesophagus which is implicated in the development of oesophageal adenocarcinoma. Diagnosis of GERD is problematic due to the range of symptoms which may be presented to the physician and symptom severity is frequently unrelated to disease severity. While endoscopic monitoring may be used to assess the presence and severity of GERD, a lack of visible damage does not necessarily indicate an absence of GERD. Techniques used to diagnose GERD include addition of an acid solution into the oesophagus in order to replicate symptoms (Bernstein test) or 24-hour intra-oesophageal pH monitoring. Proton pump inhibitors are effective in the treatment of GERD, acting to reduce the acidity of the gastric juice and hence reduce oesophageal damage and symptoms associated with GERD. Symptoms most indicative of GERD are those associated with erosive oesophagitis, including heartburn and acid regurgitation. Less common GERD-associated symptoms include chest pain, a range of ear, nose and throat conditions, and asthma. In contrast to perceptions of the disease as 'merely' heartburn, the impact on patients' quality of life can be profound. Increasing awareness of GERD by health care professionals has led to improved diagnosis and a greater appreciation of the need for maintenance therapy.

    The GH/IGF1 response of somatotropinomas to somatostatin analogues (SSA) is associated with their pattern of somatostatin receptor (sst1–sst5) expression. Recently, we demonstrated that expression of a truncated sst5-variant (sst5TMD4) can influence the secretory response of somatotropinomas to SSA-therapy; however, its potential relationship with aggressive features (e.g. invasion/proliferation) is still unknown. Here, we show that sst5TMD4 is present in 50% of non-functioning pituitary-adenomas (NFPA) (n = 30) and 89% of somatotropinomas (n = 36), its expression levels being highest in somatotropinomas > > NFPAs > > > normal pituitaries (negligible expression; n = 8). In somatotropinomas, sst5TMD4 mRNA and protein levels correlated positively, and its expression was directly associated with tumor invasiveness (cavernous/sphenoid sinus), and inversely correlated with age and GH/IGF1 reduction after 3–6 months with octreotide-LAR therapy. GNAS+ somatotropinomas expressed lower sst5TMD4 levels. ROC analysis revealed sst5TMD4 expression as the only marker, within all sst-subtypes, capable to predict tumor invasiveness in somatotropinomas. sst5TMD4 overexpression increased cell viability in cultured somatotropinoma (n = 5). Hence, presence of sst5TMD4 associates with increased aggressive features and worse prognosis in somatotropinomas, thereby providing a potentially useful tool to refine somatotropinoma diagnosis, predict outcome of clinical response to SSA-therapy and develop new therapeutic targets.

    With approximately four million people in the United States today diagnosed with dementia, one of the most devastating problems faced by caregivers and patients is dealing with aggressive behavior. Aggression occurs in half of persons diagnosed with dementia and is associated with more rapid cognitive decline, increased risk of abuse, and caregiver burden. This paper uses the Need-driven Dementia-compromised Behavior (NDB) model to explain aggression and discusses therapeutic approaches to care that combines non-pharmacological and pharmacological interventions targeting both the management of aggression crisis and preventing its future recurrence. A clinical algorithm guided by the NBD model is provided for practitioners. PMID:19215808

    A gap exists in the literature regarding aggression in autism spectrum disorders and how this behavior compares to other groups. In this multisite study, the Children's Scale for Hostility and Aggression: Reactive/Proactive and the Aggression subscale of the Child Behavior Checklist were rated for 414 children with autism spectrum disorder (autistic disorder, 69%; pervasive developmental disorder not otherwise specified, 24%; Asperger's disorder, 7%) and 243 clinic-referred children without autism spectrum disorder, aged 1-21 years (mean age about 7 years). Participants were not selected for aggressive behavior. Relative to the comparison group, children with autism spectrum disorder were reported to have less aggression and were more likely to be rated as reactive rather than proactive. Among all subjects, sex was not associated with aggression; higher IQ/adaptive behavior and older age were associated with more sophisticated types of aggression, while lower scores on IQ, adaptive behavior, and communication measures were associated with more physical aggression. The interaction between demographic variables and diagnosis was significant only for age: younger but not older children with autism spectrum disorder showed less aggression than clinic-referred controls.

  10. Schizophrenia and impulsive aggression: a heuristic inquiry with forensic and clinical implications.

    PubMed

    2008-01-01

    Assessment of a violent act committed by an offender with schizophrenia typically focuses on whether the act was due to distortions in thought or perception, i.e., delusions or hallucination. An important but less appreciated feature is the impulsivity of the act, which can have forensic and therapeutic implications. Here a modification of Barratt's classification of aggressive behavior is presented that includes premeditated (instrumental), medical (secondary), impulsive (expressive), and compulsive (instrumental and expressive) aggression. Violence due to a mental condition such as schizophrenia is considered medical, but even aggression motivated by delusions or hallucinations can also be characterized as impulsive, premeditated, or compulsive.Although research on aggression and schizophrenia is limited with regard to the impulsivity-premeditation dimension and difficult to compare, current evidence suggests this to be an important consideration in the assessment of aggression in individuals with schizophrenia, important both forensically and therapeutically. Future research on the impulsive-premeditated quality of aggressive acts by offenders with schizophrenia--research wherein aggressive behavior is defined, situational context is clarified, and diagnostic criteria are explicitly followed--should further refine our understanding of the nature of aggressive acts associated with schizophrenia. Findings from such research will undoubtedly inform assessment, treatment, and forensic relevance of schizophrenia-related physical aggression.

    Primary thyroid lymphoma (PTL) is a relatively rare malignant tumor. Aggressive PTL is extremely rare, and there is limited literature regarding the imaging features of PTL with invasion into adjacent structures, including internal jugular vein, muscles, esophagus, trachea and carotid artery. In addition, the ultrasonographic features of the cases presented in the current report differ from those reported in previous studies. In the present study, two cases of PTL, who presented to The First Affiliated Hospital of Wannan Medical College (Wuhu, China) with a short history of a rapidly growing mass in the front of their neck, are reported. Both patients had undergone ultrasound examination, and the subsequent histopathological and immunohistochemical examinations confirmed that the two masses were primary diffuse large B-cell lymphoma. The ultrasonographic findings of these two cases are discussed in the present report. PMID:27073503

    Melanomais one of the most dreaded and aggressive neoplasms, being derived from epidermal melanocytes. The majority of melanomas are seen to involve the skin, and primary mucosal melanomas account for less than 1% of all melanomas. Oral malignant melanomas (OMM) are asymptomatic at the initial presentation, but later they become painful with growth and expansion. In the late stages, the patient may present with ulceration, bleeding, tooth mobility, paresthesia, ill-fitting prosthesis, and delayed healing of the extraction sockets. Diagnosis is often delayed due to asymptomatic clinical presentation, with silent progression of the lesion. OMM are associated with poor prognosis due to their invasive and metastasizing tendencies. The condition has poor survival rates, and metastatic melanomas show even worse prognosis. The 5-year survival rate for OMM ranges 4.5-29%, with 18.5 months being the mean survival rate. The tumor is best managed by wide surgical resection; however, consideration should also be made for adjunctive therapies such as chemotherapy, immunotherapy, and radiotherapy. Recurrences may be seen even 10-15 years after the primary therapy. This paper aims to present an interesting report of aggressive OMM in a 50-year-old male patient and emphasizes the role of dental professionals in maintaining a high degree of vigilance for the pigmented lesions of the oral cavity. Pigmented lesions of uncertain origin should be routinely biopsied to rule out malignancy. Early diagnosis of this dreadful entity entails thorough history taking, physical examination, and radiographic features coupled with histopathology. PMID:27114959

    Episodic ataxia (EA) is a clinically heterogeneous group of disorders that are characterized by recurrent spells of truncal ataxia and incoordination lasting minutes to hours. Most have an autosomal dominant inheritance pattern. To date, 8 subtypes have been defined according to clinical and genetic characteristics, and five genes are known to be linked to EAs. Both EA1 and EA2, which are caused by mutations in KCNA1 and CACNA1A, account for the majority of EA, but many patients with no identified mutations still exhibit EA-like clinical features. Furthermore, genetically confirmed EAs have mostly been identified in Caucasian families. In this article, we review the current knowledge on the clinical and genetic characteristics of EAs. Additionally, we summarize the phenotypic features of the genetically confirmed EA2 families in Korea. PMID:27667184

    The goals of this study were first, to delineate the co-occurrence of parental severe physical aggression and verbal aggression toward clinic-referred adolescents, and second, to examine the interactive effects of parental severe physical aggression and verbal aggression on adolescent externalizing and internalizing behavior problems. This research involved 239 referrals of 11- to 18-year-old youth and their dual-parent families to a non-profit, private community mental health center in a semi-rural Midwest community. Multiple informants (i.e., adolescents and mothers) were used to assess parental aggression and adolescent behavior problems. More than half of clinic-referred adolescents (51%) experienced severe physical aggression and/or high verbal aggression from one or both parents. A pattern of interactive effects of mother-to-adolescent severe physical aggression and verbal aggression on adolescent behavior problems emerged, indicating that when severe physical aggression was present, mother-to-adolescent verbal aggression was positively associated with greater adolescent behavior problems whereas when severe physical aggression was not present, the links between verbal aggression and behavior problems was no longer significant. No interactive effects were found for father-to-adolescent severe physical aggression and verbal aggression on adolescent adjustment; however, higher father-to-adolescent verbal aggression was consistently linked to behavior problems above and beyond the influence of severe physical aggression. The results of this study should promote the practice of routinely assessing clinic-referred adolescents and their parents about their experiences of verbal aggression in addition to severe physical aggression and other forms of abuse.

    While endocrine therapy is the mainstay of ER+ breast cancer, the clinical effectiveness of these agents is limited by the phenomenon of acquired resistance that is associated with disease relapse and poor prognosis. Our previous studies revealed that acquired resistance is accompanied by a gain in cellular invasion and migration and also that CD44 family proteins are overexpressed in the resistant phenotype. Given the association of CD44 with tumor progression, we hypothesized that its overexpression may act to promote the aggressive behavior of endocrine-resistant breast cancers. Here, we have investigated further the role of two specific CD44 isoforms, CD44v3 and CD44v6, in the endocrine-resistant phenotype. Our data revealed that overexpression of CD44v6, but not CD44v3, in endocrine-sensitive MCF-7 cells resulted in a gain in EGFR signaling, enhanced their endogenous invasive capacity, and attenuated their response to endocrine treatment. Suppression of CD44v6 in endocrine-resistant cell models was associated with a reduction in their invasive capacity. Our data suggest that upregulation of CD44v6 in acquired resistant breast cancer may contribute to a gain in the aggressive phenotype of these cells and loss of endocrine response through transactivation of the EGFR pathway. Future therapeutic targeting of CD44v6 may prove to be an effective strategy alongside EGFR-targeted agents in delaying/preventing acquired resistance in breast cancer. PMID:27379207

    Anorectal malignant melanoma (AMM) is a very rare and aggressive disease. The purpose of this article is to review the clinical features of AMM, to understand treatment options, and optimal therapy by reviewing pertinent literature. Traditionally an abdominoperineal resection (APR) sacrificing the anal sphincter has been performed for radical resection of cancer, but recently, wide excision of AMM is attempted since quality of life after surgery is an important issue. Some authors reported that there was no difference in five-year survival between the patient who underwent an APR and wide excision. The goal of both APR and wide excision was to improve survival with R0 resection. Adjuvant chemoradiation therapy can be performed to achieve an R0 resection. AMM shows very poor prognosis. At this time, research on AMM is insufficient to suggest a treatment guideline. Thus, treatment options, and a therapeutic method should be selected carefully. PMID:25247163

    Previous studies have reported associations between aggression and Internet addiction disorder (IAD), which has also been linked with anxiety, depression, and impulsiveness. However, the causal relationship between aggression and IAD has thus far not been clearly demonstrated. This study was designed to (a) examine the association between aggression and IAD and (b) investigate the mediating effects of anxiety, depression, and impulsivity in cases in which IAD predicts aggression or aggression predicts IAD. A total of 714 middle school students in Seoul, South Korea, were asked to provide demographic information and complete the Young's Internet Addiction Test (Y-IAT), the Buss-Perry Aggression Questionnaire, the Barratt Impulsiveness Scale-11, the State-Trait Anger Expression Inventory-2, the Beck Anxiety Inventory, the Beck Depression Inventory, and the Conners-Wells Adolescent Self-Report Scale. Three groups were identified based on the Y-IAT: the usual user group (n=487, 68.2%), the high-risk group (n=191, 26.8%), and the Internet addiction group (n=13, 1.8%). The data revealed a linear association between aggression and IAD such that one variable could be predicted by the other. According to the path analysis, the clinical scales (BAI, BDI, and CASS) had partial or full mediating effects on the ability of aggression to predict IAD, but the clinical scales had no mediating effect on the ability of IAD to predict aggression. The current findings suggest that adolescents with IAD seem to have more aggressive dispositions than do normal adolescents. If more aggressive individuals are clinically prone to Internet addiction, early psychiatric intervention may contribute to the prevention of IAD.

    The aim of this study was to review of the literature to determine the radiographic and clinical maxillofacial features of pycnodysostosis emphasizing the main aspects of interest to the dentist in order to make them fit for the proper treatment of this population. It is important to make the diagnosis as early as possible in order to plan the treatment more suitable to provide a better life’s quality to the patients. The most frequent clinical maxillofacial features were: grooved palate, midfacial hypoplasia, mandibular hypoplasia and enamel hypoplasia. The most common radiographic maxillofacial features were: obtuse mandibular angle, frontal/parietal/occiptal bossing, open fontanels and sutures, multiple impacted teeth. The earlier diagnostic of pycnodysostosis has a fundamental role in general health of the patients. We consider that is very important that the dentist know recognize the radiographic and clinical maxillofacial features of pycnodysostosis, which allows correct treatment planning avoiding risks and ensuring better life’s quality to the patients.

    Oligoastrocytoma preferentially arises in the cerebral hemisphere, and a cerebellar location is unusual. We report the case of a 35-year-old woman with an aggressive cerebellar tumor histopathologically diagnosed as oligoastrocytoma World Health Organization (WHO) grade II. After partial removal of the tumor, she underwent concomitant temozolomide (TMZ) therapy with local irradiation followed by additional TMZ monotherapy. However, her symptoms gradually worsened, and chronological magnetic resonance imaging showed remarkable tumor enlargement. In accordance with the aggressive clinical course, unfavorable genetic characteristics such as the gain of the entire chromosome 7, loss of 9p, absence of 1p/19q codeletion, absence of methylation of the O6-methylguanine-deoxyribonucleic acid methyltransferase promoter, and absence of the isocitrate dehydrogenase-1 mutation were observed. The present case illustrates that these molecular characteristics represent the biological features of gliomas more closely than the histopathological diagnosis and may also suggest that infratentorial gliomas arise through a distinct tumorigenic pathway from their supratentorial counterparts.

    The term 'neuromyelitis optica' ('Devic's syndrome', NMO) refers to a syndrome characterized by optic neuritis and myelitis. In recent years, the condition has raised enormous interest among scientists and clinical neurologists, fuelled by the detection of a specific serum immunoglobulin (Ig)G reactivity (NMO-IgG) in up to 80% of patients with NMO. These autoantibodies were later shown to target aquaporin-4 (AQP4), the most abundant water channel in the central nervous system (CNS). Here we give an up-to-date overview of the clinical and paraclinical features, immunopathogenesis and treatment of NMO. We discuss the widening clinical spectrum of AQP4-related autoimmunity, the role of magnetic resonance imaging (MRI) and new diagnostic means such as optical coherence tomography in the diagnosis of NMO, the role of NMO-IgG, T cells and granulocytes in the pathophysiology of NMO, and outline prospects for new and emerging therapies for this rare, but often devastating condition.

    Objective: To compare clinical features of pediatric neuromyelitis optica (NMO) to other pediatric demyelinating diseases. Methods: Review of a prospective multicenter database on children with demyelinating diseases. Case summaries documenting clinical and laboratory features were reviewed by an adjudication panel. Diagnoses were assigned in the following categories: multiple sclerosis (MS), acute disseminated encephalomyelitis, NMO, and recurrent demyelinating disease not otherwise specified. Results: Thirty-eight cases of NMO were identified by review panel, 97% of which met the revised International Panel on NMO Diagnosis NMO-SD 2014 criteria, but only 49% met 2006 Wingerchuk criteria. Serum or CSF NMO immunoglobulin G (IgG) was positive in 65% of NMO cases that were tested; however, some patients became seropositive more than 3 years after onset despite serial testing. No patient had positive CSF NMO IgG and negative serum NMO IgG in contemporaneous samples. Other than race (p = 0.02) and borderline findings for sex (p = 0.07), NMO IgG seropositive patients did not differ in demographic, clinical, or laboratory features from seronegatives. Visual, motor, and constitutional symptoms (including vomiting, fever, and seizures) were the most common presenting features of NMO. Initiation of disease-modifying treatment was delayed in NMO vs MS. Two years after onset, patients with NMO had higher attack rates, greater disability accrual measured by overall Expanded Disability Status Scale score, and visual scores than did patients with MS. Conclusion: The new criteria for NMO spectrum disorders apply well to the pediatric setting, and given significant delay in treatment of NMO compared to pediatric MS and worse short-term outcomes, it is imperative to apply these to improve access to treatment.

    Primary Sjogren syndrome is an autoimmune condition in which dry eyes (keratoconjunctivitis sicca) and dry mouth (xerostomia) result from lymphocytic infiltration of lacrimal and salivary glands. Clinical and laboratory features of 60 primary Sjogren syndrome patients seen at our clinic during the past three years are presented. These patients illustrate the wide spectrum of extraglandular features that may occur as a result of lymphoid infiltration of lung, kidney, skin, stomach, liver, and muscle. They further emphasize the difficulty in classifying a patient as primary or secondary Sjogren syndrome (ie, sicca symptoms associated with systemic lupus erythematosus, rheumatoid arthritis, or scleroderma), particularly early in the disease course. As an initial step in understanding the pathogenesis, the lymphocytes that infiltrate the salivary glands and lymph nodes were characterized by using monoclonal antibodies that recognize distinct lymphocyte subsets and by using in vitro functional assays. These studies have demonstrated that affected tissues have infiltrates of T cells with helper/inducer activity and with a high frequency of "activation antigens." The immunohistologic techniques are useful in differentiating "benign" and "pseudolymphoma" lesions (both due predominantly to T cells) from non-Hodgkin lymphoma (usually due to B-cell infiltrates). Although there is no "cure" for primary Sjogren syndrome patient's symptoms may be significantly improved by measures aimed at prevention of ocular and dental complications and by the recognition of extraglandular features that may be amenable to specific treatment.

    Adenomatoid odontogenic tumor (AOT) is a rare tumor comprising only 3% of all odontogenic tumors. It is a benign, encapsulated, noninvasive, nonaggressive, slowly growing odontogenic lesion associated with an impacted tooth. These lesions may go unnoticed for years. The usual treatment is enucleation and curettage, and the lesion does not recur. Here, we present a rare case of an unusually large aggressive AOT of maxilla associated with impacted third molar. The authors also discuss clinical, radiographic, histopathologic, and therapeutic features of the case. Subtotal maxillectomy with simultaneous reconstruction of the surgical defect with temporalis myofascial flap was planned and carried out. PMID:27095910

    The term ‘neuromyelitis optica’ (‘Devic's syndrome’, NMO) refers to a syndrome characterized by optic neuritis and myelitis. In recent years, the condition has raised enormous interest among scientists and clinical neurologists, fuelled by the detection of a specific serum immunoglobulin (Ig)G reactivity (NMO-IgG) in up to 80% of patients with NMO. These autoantibodies were later shown to target aquaporin-4 (AQP4), the most abundant water channel in the central nervous system (CNS). Here we give an up-to-date overview of the clinical and paraclinical features, immunopathogenesis and treatment of NMO. We discuss the widening clinical spectrum of AQP4-related autoimmunity, the role of magnetic resonance imaging (MRI) and new diagnostic means such as optical coherence tomography in the diagnosis of NMO, the role of NMO-IgG, T cells and granulocytes in the pathophysiology of NMO, and outline prospects for new and emerging therapies for this rare, but often devastating condition.

    2013-02-01

    In this review, we delineate clinical, electrodiagnostic, and radiographic features of ulnar mononeuropathies. Ulnar neuropathy at the elbow (UNE) is most commonly due to lesions at the level of the retroepicondylar groove (RTC), with approximately 25% at the humeroulnar arcade (HUA). The term 'cubital tunnel syndrome' should be reserved for the latter. The diagnostic accuracy of nerve conduction studies is limited by biological (e.g. low elbow temperature) and technical factors. Across-elbow distance measurements greater than 10 cm improve diagnostic specificity at the expense of decreased sensitivity. Short-segment incremental studies can differentiate lesions at the HUA from those at the RTC.

    Amyloidosis is a rare disorder in which insoluble amyloid proteins are deposited in body organs, causing abnormal protein build-up in tissues and eventually leading to organ dysfunction and death. It affects less than 200,000 people in the United States, classifying it as a rare disease according to the National Institutes of Health. Definitive determination of the underlying protein is critical since prognosis and treatment of amyloidosis can vary widely depending on the responsible protein. The following paper describes the various types and clinical features of amyloidosis and provides an overview of current diagnostic tools and therapies. PMID:23227278

    Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by progressive damage of synovial-lined joints and variable extra-articular manifestations. Tendon and bursal involvement are frequent and often clinically dominant in early disease. RA can affect any joint, but it is usually found in metacarpophalangeal, proximal interphalangeal and metatarsophalangeal joints, as well as in the wrists and knee. Articular and periarticular manifestations include joint swelling and tenderness to palpation, with morning stiffness and severe motion impairment in the involved joints. The clinical presentation of RA varies, but an insidious onset of pain with symmetric swelling of small joints is the most frequent finding. RA onset is acute or subacute in about 25% of patients, but its patterns of presentation also include palindromic onset, monoarticular presentation (both slow and acute forms), extra-articular synovitis (tenosynovitis, bursitis), polymyalgic-like onset, and general symptoms (malaise, fatigue, weight loss, fever). The palindromic onset is characterized by recurrent episodes of oligoarthritis with no residual radiologic damage, while the polymyalgic-like onset may be clinically indistinguishable from polymyalgia rheumatica in elderly subjects. RA is characteristically a symmetric erosive disease. Although any joint, including the cricoarytenoid joint, can be affected, the distal interphalangeal, the sacroiliac, and the lumbar spine joints are rarely involved. The clinical features of synovitis are particularly apparent in the morning. Morning stiffness in and around the joints, lasting at least 1 h before maximal improvement is a typical sign of RA. It is a subjective sign and the patient needs to be carefully informed as to the difference between pain and stiffness. Morning stiffness duration is related to disease activity. Hand involvement is the typical early manifestation of rheumatoid arthritis. Synovitis involving the metacarpophalangeal

    2014-01-01

    There are two classifications of hereditary hyperprolinemia: type I (HPI) and type II (HPII). Each type is caused by an autosomal recessive inborn error of the proline metabolic pathway. HPI is caused by an abnormality in the proline-oxidizing enzyme (POX). HPII is caused by a deficiency of Δ-1-pyrroline-5-carboxylate (P5C) dehydrogenase (P5CDh). The clinical features of HPI are unclear. Nephropathy, uncontrolled seizures, mental retardation or schizophrenia have been reported in HPI, but a benign phenotype without neurological problems has also been reported. The clinical features of HPII are also unclear. In addition, the precise incidences of HPI and HPII are unknown. Only two cases of HPI and one case of HPII have been identified in Japan through a questionnaire survey and by a study of previous reports. This suggests that hyperprolinemia is a very rare disease in Japan, consistent with earlier reports in Western countries. The one case of HPII found in Japan was diagnosed in an individual with influenza-associated encephalopathy. This suggests that HPII might reduce the threshold for convulsions, thereby increasing the sensitivity of individuals with influenza-associated encephalopathy. The current study presents diagnostic criteria for HPI and HPII, based on plasma proline level, with or without measurements of urinary P5C. In the future, screening for HPI and HPII in healthy individuals, or patients with relatively common diseases such as developmental disabilities, epilepsy, schizophrenia or behavioral problems will be important.

    months (median 9 months). Eleven patients (41%) died of the disease in 0.5-20 months, four are alive with disease and twelve patients have no evidence of disease. Endometrial and ovarian carcinomas with undifferentiated components have a broad histologic differential diagnosis, but they show specific histologic features that should enable accurate diagnosis. These tumors can occur in young women, may be associated with microsatellite instability and behave in a clinically aggressive manner.

    Twenty patients with delirium tremens and related states were investigated from the time of admission until the acute state was over. Using strict diagnostic criteria the material was divided into two groups according to the severity of the clinical condition; nine patients had fully developed delirium tremens (grade 3), 11 patients had a less severe clinical state, known as "Predelirium" (grade 2). The material was found to be representative for the condition under discussion. Patients with grade 2 were admitted during the day and the evening, but not during the night; patients with fully developed delirium tremens (grade 3) were admitted during both the day and the night, and this difference is discussed. The two groups had the same pattern of alcohol abuse, but patients with proper delirium tremens had had a drinking bout preceding the acute state; this was not seen among patients with a less severe clinical state. Patients with grade 2 had had symptoms like sleep disturbances and gastro-intestinal disturbances for 12-24 hours before the admission, whereas grade 3 patients had had such symptoms for about 48 hours. Patients with grade 2 stopped drinking when the first symptoms of the acute state appeared, whereas patients with fully developed delirium tremens continued to drink in spite of their condition. These anamnestic were supported by the finding that significantly more patients with proper delirium tremens had alcohol in the blood--several even concentrations about 2 g/l--at the time of admission compared to patients with a less severe clinical state. This lack of "latency period", which previously has been described as a typical feature in the development of delirium tremens, is discussed. It is concluded that due to the methodology used, it has been possible to point out some of the differences between the milder, often harmless, conditions and the potentially serious, fully developed delirium tremens.

    Recent advances in neuropathology, genotyping, and physiochemical characterization of proteins have allowed for the classification and verification of MM2-thalamic Creutzfeldt-Jakob disease (CJD). CJD is a fatal neurodegenerative illness belonging to the transmissible spongiform encephalopathies, also known as prion diseases. Sporadic CJD is generally classified by the genotype at codon 129 of the prion protein gene and the distinct physiochemical features of the pathologic prion protein (PrP(sc)). The entity is characterized by methionine homozygosity at codon 129, type 2 PrP(sc), and, primarily, thalamic pathology (MM2-thalamic CJD). It shares clinical and pathologic similarities with the genetic prion disorder fatal familial insomnia; the MM2-thalamic phenotype has therefore been called sporadic fatal insomnia (SFI). SFI may also present like other neurodegenerative diseases, and common diagnostic findings that are seen in other forms of sporadic CJD may be absent.

    Purpose Although Bednar's aphthae are common and regress spontaneously, these lesions may lead to feeding intolerance and are often misdiagnosed, rendering examinations useless. This study sheds new light on the clinical features of Bednar's aphthae. Methods Sixteen neonates and infants were newly diagnosed with Bednar's aphthae via routine health check-ups in an outpatient clinic. Medical records were retrospectively reviewed, and the following parameters were analyzed; sex, gestational age, birth weight, mode of delivery, and perinatal problems. A physical examination was carried out during the next outpatient visit to examine the healing process and check for the existence of scars or complications. Results Initial presentation included changes in feeding habits (n=10), longer feeding time, reduced intake, and increased irritability. In 6 patients, Bednar's aphthae were discovered incidentally, without prior symptoms. Feeding posture and method of feeding are important causes of Bednar's aphthae. Eleven patients were fed in a horizontal position, whereas 5 patients were fed in a semiseated position. Fifteen patients were bottle-fed, whereas 1 patient was exclusively breastfed. After correcting the feeding position, the ulcerative lesions disappeared within 1 month of diagnosis. During the follow-up period, lesions did not recur in any of the patients. Conclusion This study suggests that Bednar's aphthae are caused by mechanical pressure. A diagnosis of Bednar's aphthae should be considered when lesions are found on the palate of infants and when symptoms seem to be feeding related. Proper education of parents can both treat Bednar's aphthae and easily prevent its recurrence. PMID:26893601

    A few authors have described the clinical picture of dysthymia in groups of elderly patients and pointed out differences from literature reports of dysthymia in younger adults. The present study, an attempt to analyze age effects on clinical characteristics of dysthymia throughout a lifetime, was performed in a sample of 106 patients, all aged > or =18 years, who were diagnosed according to DSM-IV. The patients were evaluated using: (1) a semistructured interview to assess clinical features, family history and previous treatments; (2) the Hamilton Depression Rating Scale; (3) the Interview for Recent Life Events; and (4) the Structured Clinical Interview for DSM-IV Disorders. Statistical analysis with stepwise logistic regression revealed that age was positively related to concomitant medical illnesses and to the total score of recent life events, but negatively related to the presence of avoidant or dependent personality disorders. The data suggested different etiologic pathways in older and younger patients. Dysthymia appeared to be associated in younger adults with abnormalities of personality; in the elderly, with a history of health problems and life losses.

    The clinical and neurophysiological findings in six Australian children with generalized tick paralysis are described. Paralysis is usually caused by the mature female of the species Ixodes holocyclus. It most frequently occurs in the spring and summer months but can be seen at any time of year. Children aged 1-5 years are most commonly affected. The tick is usually found in the scalp, often behind the ear. The typical presentation is a prodrome followed by the development of an unsteady gait, and then ascending, symmetrical, flaccid paralysis. Early cranial nerve involvement is a feature, particularly the presence of both internal and external ophthalmoplegia. In contrast to the experience with North American ticks, worsening of paralysis in the 24-48 h following tick removal is common and the child must be carefully observed over this period. Death from respiratory failure was relatively common in the first half of the century and tick paralysis remains a potentially fatal condition. Respiratory support may be required for > 1 week but full recovery occurs. This is slow with several weeks passing before the child can walk unaided. Anti-toxin has a role in the treatment of seriously ill children but there is a high incidence of acute allergy and serum sickness. Neurophysiological studies reveal low-amplitude compound muscle action potentials with normal motor conduction velocities, normal sensory studies and normal response to repetitive stimulation. The biochemical structure of the toxin of I. holocyclus has not been fully characterized but there are many clinical, neurophysiological and experimental similarities to botulinum toxin.

    2001-07-01

    To investigate the clinical features of Rathke's cleft cysts (RCCs), we retrospectively analyzed 15 cases with histologically confirmed RCCs. All patients underwent formal testing of visual field, endocrinological evaluation and magnetic resonance imagings. As overall presenting symptoms, endocrine disturbance was the most common symptoms, followed by visual disturbance and headache. Among the endocrine disturbances based on adenohypophysial dysfunction, hyperprolactinemia was most common. Considering the size of RCCs, RCCs could induce hyperprolactinemia only when the cysts became large enough to compress the infundibular system. Our series showed relative high incidence of pituitary dwarfism and diabetes insipidus (DI). These facts indicated that RCCs could evoke hyposecretion of growth hormone in young patients and DI in aged patients by direct compression of the pituitary gland in the early stage of progression. All cases who had headache had no other symptoms. We could not prove the evidence that RCCs could induce headaches in these cases. This might be suggested that headache could not be a sole symptom in cases of RCCs. PMID:11516552

    Background: It is well-recognized fact that periodontal diseases are caused by multifactorial etiologies, in which microorganisms play an important role. An essential component of therapy is to eliminate or manage these pathogens. This has been traditionally accomplished through mechanical means by scaling and root planning which is ineffective in some of the aggressive periodontal diseases. These aggressive diseases involve particular groups of microorganisms which are not eliminated by mechanical means; and they require anti-infective therapy, which includes local and systemic antimicrobials. This approach of therapy is of interest to periodontist due to the aforementioned shortcomings of conventional methods. Materials and Methods: A manual and electronic search was made for human studies up to March 2011 that presented clinical and microbiological data for the efficacy of a systemic antibiotics in generalized aggressive periodontitis along with scaling and root planning. A systematic approach was followed by two independent reviewers and included eligibility criteria for study inclusion, quality assessment, and determination of outcome measures, data extraction, data synthesis, and drawing of conclusion. Results: Only three randomized controlled human trials qualified, and they concluded that both scaling and root planing (SRP) mono-therapy and SRP with antibiotics proves beneficial in improving clinical and microbiological parameters in aggressive periodontitis. Better results were seen in SRP with antibiotic groups as compared with SRP alone. Conclusion: Because of the insufficient quantity and heterogenecity of studies, no adequate evidence could be gathered to use the beneficial effects of these antibiotics along with SRP in aggressive periodontitis compared with SRP alone.

    The effects of Aggression Replacement Training (ART) were explored in a group of Dutch violent young men aged 16 to 21 years, who were obliged by the court to follow a treatment program in a forensic psychiatric outpatient clinic. To evaluate the training, patients completed a set of self-report questionnaires at three moments in time: at intake/before a waiting period, after the waiting period/before the training, and after the training. During the waiting period, the patients did not change on most measures, although they displayed a significant increase in anger. The patients who completed the therapy scored significantly lower on psychopathy than the patients who dropped out. The training produced significant decreases in physical aggression and social anxiety and showed trends toward a decline in self-reported hostility, general aggression, and anger. After the training, the patients scored comparably with a reference group on measures of hostility and aggressive behavior. Altogether, these results provide tentative support for the efficacy of the ART for violent young men referred to forensic psychiatric outpatient settings.

    Objectives While the majority of HPV+ oropharyngeal squamous cell carcinomas have a favorable prognosis, we search for markers of poor prognosis by carefully examining a subset of highly-aggressive cases. Study Design Seven patients with HPV+ oropharyngeal cancer who presented with non-pulmonary distant metastasis or developed distant metastasis post-treatment were identified. Eight control cases were chosen which responded well to treatment. Pathology and radiological studies were reviewed and compared. Results Two cases displayed a small cell carcinoma (SmCC) component upon pathologic review. Biomarker analysis revealed lower expression of NOTCH1 in the aggressive cohort in comparison to controls (p=0.04). Cases showed a predominance of clustering of lymph nodes, extracapsular spread and central tumor necrosis. Conclusion While most HPV-related oropharyngeal cancers display a positive prognosis, it is evident that there is a subset, which behave more aggressively. This early investigation identifies pathologic and radiologic features that may help to predict this behavior. PMID:23770280

    In renal cell carcinoma (RCC), tumor cells with rhabdoid features are characterized by eccentric nuclei, prominent nucleoli, and eosinophilic cytoplasm with intracytoplasmic inclusion bodies. In RCC, tumor cells have also been observed resembling rhabdomyoblasts or rhabdoid but without intracytoplasmic inclusion bodies, and here, we defined these rhabdoid-like features of these cells. To this end, we studied a series of clear cell RCC (ccRCC) with rhabdoid features and compared them with a series of ccRCC with rhabdoid-like features to clarify the differences in the immunohistochemical profile and biological behavior. From 695 cases of ccRCC (80.8 % of all RCCs), 18 cases with rhabdoid features (2.1 % of all RCCs) and 25 cases with rhabdoid-like features (2.9 % of all RCCs) were investigated. The 5-year survival rate for ccRCC with rhabdoid features was 44.7 % and for ccRCC with rhabdoid-like features 30.3 %. Although ccRCC with rhabdoid features showed immunohistochemical co-expression of epithelial markers and vimentin as seen in malignant rhabdoid tumors, ccRCC with rhabdoid-like features showed no such co-expression. Multivariate analyses of cancer-specific survival revealed that perinephric tissues invasion was an independent prognostic factor in ccRCC with rhabdoid features (p = 0.0253) but not in ccRCC with rhabdoid-like features. In summary, although their prognosis is similar, the marker profile and pattern of extension of ccRCC with rhabdoid-like is different from that of ccRCC with rhabdoid features. Therefore, ccRCC with rhabdoid-like features should be distinguished from ccRCC with rhabdoid features.

    Aggressive B-cell lymphomas incorporate a wide spectrum of lymphomas that pose challenges in diagnosis as well as treatment. We evaluated the clinicopathological features of 44 patients with aggressive B-cell lymphomas which were classified into 3 groups based on the World Health Organization 2008 classification as follows: including 30 cases of diffuse large B-cell lymphoma (DLBCL), 8 cases of Burkitt lymphoma (BL) and 6 cases of B-cell lymphoma, unclassifiable, with features intermediate between Burkitt lymphoma and diffuse large B-cell lymphoma (BCLU). Male predominance was observed in BL and BCLU groups and the mean age varied from 29 years in BL, 61 years in DLBCL and 70 years in BCLU. Patients with BCLU presented at more advanced stages and had a higher international prognostic index. By immunohistochemistry, they shared characteristics of both BL (including more frequent expression of SOX11) and DLBCL. FISH analyses showed three cases with more than one rearrangement: one MYC/BCL2 and two BCL2/BCL6, in addition to which one case with BCL2/IGH translocation and another with MYC rearrangement were also detected. The mean follow-up survival time of BCLU was 6.6 months, which was significantly shorter in comparison to DLBCL (31 months) and BL (30 months), respectively. The importance of recognizing this BCLU group relies on its different clinical course, poor prognosis and shorter survival than DLBCL and BL. An accurate diagnosis is critical for risk stratification and to improve therapeutic approaches and outcomes.

    We report a woman with acute arsenic poisoning, who developed an erythroderma with vesicles and pustules after the ingestion of 8-16 g of sodium arsenite. Simultaneously, she presented a herpes simplex virus infection. Skin biopsies showed unique features which included multiple small pigment granules inside and outside the histiocytes. In our opinion, these findings are consistent with acute arsenic poisoning, and constitute the first histological description of this entity in skin.

    2015-11-01

    Cachexia is a clinically relevant syndrome which impacts on quality of life, morbidity and mortality of patients suffering from acute and chronic diseases. The hallmark of cachexia is muscle loss, which is triggered by disease-associated inflammatory response. Cachexia is a continuum and therefore a staging system is needed. Initially, a three-stage system (i.e. pre-cachexia, cachexia and refractory cachexia) was proposed. More recent evidence supports the use of a five-stage classification system, based on patient's BMI and severity of weight loss, to better predict clinical outcome. Also, large clinical trials in cancer patients demonstrated that cachexia emerging during chemotherapy has greater influence on survival than weight loss at baseline. Therefore, becoming widely accepted is the importance of routinely monitoring patients' nutritional status to detect early changes and diagnose cachexia in its early phases. Although cachexia is associated with the presence of anabolic resistance, it has been shown that sustained yet physiological hyperaminoacidaemia, as well as the use of specific nutrients, is able to overcome impaired protein synthesis and revert catabolism. More importantly, clinical evidence demonstrates that preservation of nutritional status during chemotherapy or improvement of body weight after weight loss is associated with longer survival in cancer patients.

  9. Parasomnias: clinical features and forensic implications.

    Parasomnias are undesirable behavioral or experiential phenomena arising from the sleep period. Once felt to be a unitary phenomenon, it is now clear that a wide variety of sleep disorders are capable of resulting in complex behaviors arising during sleep. The most common are disorders of arousal and rapid eye movement sleep disorder. Less common conditions include nocturnal seizures and psychogenic dissociative states. Malingering and Munchausen syndrome by proxy, while they are not actually parasomnias, may masquerade as parasomnias. Careful clinical and sleep laboratory evaluation can usually provide an accurate diagnosis with effective therapeutic implications. Due to the potential forensic implications, sleep medicine specialists may be asked to participate in legal proceedings resulting from sleep-related violence. An awareness of the spectrum of such behaviors, and their clinical and legal evaluation, is becoming more important in the practice of sleep medicine.

    The current report presents a case of a 78-year-old male with sacral chordoma, showing an aggressive clinical course. The patient underwent sacral resection, however, nine months later, multiple metastases were detected by magnetic resonance imaging. The metastases progressed rapidly and 15 months following surgery the patient succumbed to respiratory dysfunction. An autopsy revealed multiple metastases of the lung, liver, heart, kidneys and vertebrae. Pathologically, the tumors did not show proliferation of anaplastic cells or dedifferentiation; however, the metastatic tumor cells were smaller than the primary tumor cells. The Ki-67 labeling indices were <5% in all of the patient’s tumors, therefore, the capacity for cellular proliferation of the tumors was considered to be low. Chordoma in adults are generally slow-growing tumors and are associated with a relatively prolonged course and frequent local recurrences. Therefore, it must be recognized that chordoma may grow rapidly and show an aggressive clinical course, even when the Ki-67 labeling index is low. PMID:24765153

    2014-01-01

    Background In psychiatry, most of the focus on patient aggression has been in adolescent and adult inpatient settings. This behaviour is also common in elderly people with mental illness, but little research has been conducted into this problem in old age psychiatry settings. The attitudes of clinical staff toward aggression may affect the way they manage this behaviour. The purpose of this study was to examine the attitudes of clinical staff toward the causes and management of aggression in acute old age psychiatry inpatient settings. Methods A convenience sample of clinical staff were recruited from three locked acute old age psychiatry inpatient units in Melbourne, Australia. They completed the Management of Aggression and Violence Scale, which assessed the causes and managment of aggression in psychiatric settings. Results Eighty-five staff completed the questionnaire, comprising registered nurses (61.1%, n = 52), enrolled nurses (27.1%, n = 23) and medical and allied health staff (11.8%, n = 10). A range of causative factors contributed to aggression. The respondents had a tendency to disagree that factors directly related to the patient contributed to this behaviour. They agreed patients were aggressive because of the environment they were in, other people contributed to them becoming aggressive, and patients from certain cultural groups were prone to these behaviours. However, there were mixed views about whether patient aggression could be prevented, and this type of behaviour took place because staff did not listen to patients. There was agreement medication was a valuable approach for the management of aggression, negotiation could be used more effectively in such challenging behaviour, and seclusion and physical restraint were sometimes used more than necessary. However, there was disagreement about whether the practice of secluding patients should be discontinued. Conclusions Aggression in acute old age psychiatry inpatient units occurs

  13. Cortical auditory disorders: clinical and psychoacoustic features.

    The symptoms of two patients with bilateral cortical auditory lesions evolved from cortical deafness to other auditory syndromes: generalised auditory agnosia, amusia and/or pure word deafness, and a residual impairment of temporal sequencing. On investigation, both had dysacusis, absent middle latency evoked responses, acoustic errors in sound recognition and matching, inconsistent auditory behaviours, and similarly disturbed psychoacoustic discrimination tasks. These findings indicate that the different clinical syndromes caused by cortical auditory lesions form a spectrum of related auditory processing disorders. Differences between syndromes may depend on the degree of involvement of a primary cortical processing system, the more diffuse accessory system, and possibly the efferent auditory system.

    Corneal neovascularization is defined as the presence of vessels within the normally avascular corneal stroma. This physiopathological process is the consequence of local hyper-expression of pro-angiogenic factors in response to tissue damage. These new vessels (neovessels), initially immature and poorly developed, predispose the cornea to lipid exudation, inflammation, and scarring. Additionally, the influx of vascular cells into the stroma induces a loss of the cornea's immune privilege, resulting in a higher rate of graft rejection. In this literature review, we touch on epidemiological, physiopathological, and clinical aspects of corneal neovascularization, as well as secondary complications.

    Moyamoya disease (MMD) is a chronic, occlusive cerebrovascular disease characterized by progressive stenosis at the terminal portion of the internal carotid artery and an abnormal vascular network at the base of the brain. Although its etiology remains unknown, recent genetic studies identified RNF213 in the 17q25-ter region as an important susceptibility gene of MMD among East Asian populations. Possibly because of genetic differences, MMD is relatively common in people living in East Asian countries such as Korea and Japan, compared to those in the Western Hemisphere. The prevalence of MMD appears to be slightly lower among Chinese, compared to Koreans or Japanese. There are two peaks of incidence with different clinical presentations, at around 10 years and 30-40 years. The peak appears to occur later in women than men. In children, ischemic symptoms, especially transient ischemic attacks, are predominant. Intellectual decline, seizures, and involuntary movements are also more common in this age group. In contrast, adult patients present with intracranial hemorrhage more often than pediatric patients. In patients with MMD, intracerebral hemorrhage is more often accompanied by intraventricular hemorrhage than in patients with hypertensive intracerebral hemorrhage. These different age peaks and different clinical presentations in each age group are also observed in MMD patients in the USA. Catheter angiography is the diagnostic method of choice. Magnetic resonance (MR) angiography and computed tomographic angiography are noninvasive diagnostic methods. High-resolution vessel wall MR imaging also helps diagnose MMD by revealing concentric vessel wall narrowing with basal collaterals. PMID:26846755

    Sarcoidosis is a granulomatous disease of unknown cause. This proteiform disease is characterized by an almost constant and often predominant lung involvement. The natural history of disease is difficult to predict at presentation. Diagnosis is based on a compatible clinical and radiological presentation and evidence of non-caseating granulomas. Exclusion of alternative diseases is also required according to clinical presentation. Biopsy samples of superficial lesions should be considered before other sites like per-endoscopic bronchial biopsies or endobronchial ultrasound-guided transbronchial needle aspiration. Therapeutic strategy for lung disease has to take into account the possible spontaneous resolution observed in newly diagnosed patients. Corticosteroids are the first choice when a treatment is decided, which concerns half of patients. Second and third line therapy are based respectively on immunosuppressive drugs and anti-TNFα drugs. Sarcoidosis mortality and morbidity are mainly linked to advanced pulmonary sarcoidosis - lung fibrosis, pulmonary hypertension, bronchial stenosis and chronic pulmonary aspergillosis. "Non anti-inflammatory" treatments have to be considered as well. Clinicians have an essential role in treatment indication, end-point targets and evaluation of response to treatment during follow-up and in finding the best benefice to risk balance. Progress made on pharmacogenetics may offer more personalized treatments for the patients. PMID:26897112

    The mucopolysaccharidoses (MPS) are a group of rare (orphan) diseases, characterised by a deficiency of enzymes involved in the metabolism of glycosaminoglycans (GAGs) at lysosomal level. When there is a deficiency of a particular enzyme there is an accumulation of GAGs in the cells resulting in progressive cellular damage, which can affect multiple organ systems and lead to organ failure. Diagnosis is based on knowledge of the clinical manifestations, performing biochemical analyses to identify the type of GAG that is accumulating, and confirm the type of disorder with the corresponding enzymatic determination. Their identification is essential to initiate early treatment, taking into account that multidisciplinary management and enzyme replacement therapy is available for MPS I (Hurler syndrome), MPS II (Hunter syndrome), MPS IV (Morquio syndrome), and MPS VI (Maroteaux-Lamy syndrome. In this review, an analysis is made of each of these syndromes, as well as their diagnosis and treatment.

    Background: The success of combined periodontal and orthodontic approach in the treatment of aggressive periodontitis patients with the pathologic extruded anterior teeth is a main concern and stability of the treatment results is an important factor to evaluate the treatment. The present study investigated the periodontal parameters at the end of the orthodontic treatment in patients with the aggressive periodontitis. Materials and Methods: Eight patients with an aggressive periodontal disease, extruded maxillary incisors, infrabony defects and probing depth of ≥5 mm were enrolled in this clinical trial (before, after). After periodontal therapy, orthodontic treatment was carried out for intrusion and alignment of teeth. Plaque index (PI), probing pocket depth (PPD), distance between incisal edge and interdental papilla, root length (RL), and defect dimensions (depth and width) were examined at the end of treatment and three as well as 6 months afterward. The data were subjected to repeated measure ANOVA test. P < 0.05 was considered as significant. Results: There was statistically significant decrease in PPD, PI, and depth of the defects during T0, T3 and T6 (P < 0.05). No significant differences were observed in the RL and distance between incisal edge and interdental papilla (P = 0.95). Furthermore, width of the defects demonstrated significant decrease up to T3 (P = 0.042) while no significant changes from 3 months to 6 months were noted (P = 0.59). Conclusion: The results showed that combined periodontal and orthodontic approach would be a successful treatment with acceptable stability in the case of regular follow-up visits and controlled oral hygiene habits.

    The concept of aggression is important to nursing because further knowledge of aggression can help generate a better theoretical model to drive more effective intervention and prevention approaches. This paper outlines a conceptual analysis of aggression. First, the different forms of aggression are reviewed, including the clinical classification and the stimulus-based classification. Then the manifestations and measurement of aggression are described. Finally, the causes and consequences of aggression are outlined. It is argued that a better understanding of aggression and the causal factors underlying it are essential for learning how to prevent negative aggression in the future. PMID:15371137

    1988-05-01

    Thirty patients with functional and/or morphological abnormalities of respiratory tract cilia were identified. The diagnosis of primary ciliary dyskinesia was based on observed abnormalities of ciliary ultrastructure or beating in vitro (beat pattern, beat frequency or percentage of motile cilia). Beat frequency and motility indices approached the normal range in some cases and suggests that the term 'immotile cilia syndrome' is not appropriate. Morphological abnormalities were most commonly due to deficiency of dynein arms, affecting the outer arms (n = 7), inner arms (n = 3) or both (n = 10). Examples of radial spoke and microtubular defects were also identified but in seven subjects ciliary ultrastructure was normal. In six patients paired samples of nasal and bronchial cilia were obtained and showed consistent abnormalities of motility and ultrastructure. Adenosine triphosphate and adenosine triphosphatase did not restore in vitro motility when added to dynein deficient cilia. The clinical picture was of life-long sinusitis and recurrent bronchial infection but the spectrum was broader than that encompassed by Kartagener's triad (dextrocardia, sinusitis and bronchiectasis). Fourteen patients had normal cardiac situs and definite or highly suggestive evidence of bronchiectasis was present in only 17 patients. Radiological evidence of sinusitis was common but absence of frontal sinuses was not universal. Chronic serous otitis media was a frequent finding but deafness was rarely profound. Fertility problems were common but were not universal in female subjects. Lung function testing revealed evidence of airflow obstruction but this was mild in most cases. PMID:2975807

    The symptomatic characteristics and psychosocial factors of belching were analyzed through questionnaire, and the pathophysiology of belch was studied with the combined methods of high-resolution manometry and impedance (HRM-IMP). 21 consecutively-enrolled patients with repeated belching, were conducted a questionnaire survey, and the data were analyzed with Pearson correlation analysis and exact propability method. 10 patients were performed HRM-IMP. 20 patients met the diagnostic criteria of belch, among who 17 cases had overlapped symptoms, and the functional dyspepsia was the most common, followed by gastroesophageal reflux disease; 16 patients experienced mental stimulation or negative events; 12 cases existed anxiety and (or) depression; 8 cases had neurotic personality. The number of the overlapped symptoms was associated with the anxiety status, while the belch severity had nothing to do with the anxiety/depression status. Among the 10 patients who accepted HRM-IMP, 9 existed the esophageal motility dysfunction, and 9 had supra-gastric belching. Belch had a variety of clinical manifestations, related to the mood changes and the environmental stress, and normally was combined with the abnormalities of psychology and personality traits. The belch patients normally experienced the esophageal motility disorders, among which the typical pattern was supra-gastric belching. PMID:26885161

    Candidiasis is the most commonly encountered fungal infection, and oral candidiasis is often observed as a local opportunistic infection. Oral candidiasis is clinically divided into three types: acute forms, chronic forms, and Candida-associated lesions. Candida adhesion and multiplication are largely regulated by the local and systemic factors of the host. The local factors include impairment of the oral mucosal integrity, which is usually impaired by hyposalivation, anticancer drugs/radiation for head and neck cancers, denture wearing, a decrease in the oral bacterial population, and poor oral hygiene. Among Candida species, oral candidiasis is mostly caused by Candida albicans (C. albicans), C. glabrata, or C. tropicalis. Oral Candida induces a variety of symptoms, such as oral mucosal inflammation manifesting as an uncomfortable feeling, pain, erythema, erosion, taste abnormalities, and hyperplasia of the oral mucosa. Candida overgrowth in the oral cavity may disseminate to distant organs. Therefore, in order to avoid the sequelae of systemic candidiasis, oral candidiasis should be rapidly controlled. Oral candidiasis is usually treated by the local application of antifungal drugs. However, oral candidiasis occasionally escapes the control of such local treatment due to the development of multi-drug resistant Candida strains and species or due to the suppression of salivation or cellular immune activity. When drug-resistant strains are suspected as the pathogens and when the host is generally compromised, the oral administration of combinations of antifungal drugs, enhancement of cellular immune activity, and improvement of the nutritional condition are recommended.

     Narcolepsy is a chronic hypersomnia characterized by excessive daytime sleepiness (EDS) and manifestations of disrupted rapid eye movement sleep stage (cataplexy, sleep paralysis, and hypnagogic/hypnopompic hallucinations). Mechanisms underlying narcolepsy are not fully understood. Experimental data indicate that the disease is caused by a loss of hypocretin neurons in the hypothalamus, likely due to an autoimmune process triggered by environmental factors in susceptible individuals. Most patients with narcolepsy and cataplexy have very low hypocretin-1 levels in the cerebrospinal fluid. An appropriate clinical history, polysomnogram, and multiple sleep latency test are necessary for diagnosis of the disease. Additionally, two biological markers, i.e., cerebrospinal fluid hypocretin-1 levels and expression of the DQB1*0602 gene, are used. The treatment of narcolepsy is aimed at the different symptoms that the patient manifests. Excessive daytime sleepiness is treated with psychostimulants (amphetamine-like, modafinil and armodafinil). Cataplexy is treated with sodium oxybate (GHB), tricyclic antidepressants, or selective serotonin and noradrenaline reuptake inhibitors. Sleep paralysis, hallucinations, and fragmented sleep may be treated with sodium oxybate. Patients with narcolepsy should follow proper sleep hygiene and avoid strong emotions. PMID:23175331

    The RAS/MAPK pathway proteins with germline mutations in their respective genes are associated with some disorders such as Noonan, LEOPARD (LS), neurofibromatosis type 1, Costello and cardio-facio-cutaneous syndromes. LEOPARD is an acronym, mnemonic for the major manifestations of this disorder, characterized by multiple lentigines, electrocardiographic abnormalities, ocular hypertelorism, pulmonic stenosis, abnormal genitalia, retardation of growth, and sensorineural deafness. Though it is not included in the acronym, hypertrophic cardiomyopathy is the most frequent cardiac anomaly observed, representing a potentially life-threatening problem in these patients. PTPN11, RAF1 and BRAF are the genes known to be associated with LS, identifying molecular genetic testing of the 3 gene mutations in about 95% of affected individuals. PTPN11 mutations are the most frequently found. Eleven different missense PTPN11 mutations (Tyr279Cys/Ser, Ala461Thr, Gly464Ala, Thr468Met/Pro, Arg498Trp/Leu, Gln506Pro, and Gln510Glu/Pro) have been reported so far in LS, 2 of which (Tyr279Cys and Thr468Met) occur in about 65% of the cases. Here, we provide an overview of clinical aspects of this disorder, the molecular mechanisms underlying pathogenesis and major genotype-phenotype correlations. PMID:23239957

    Multiple sclerosis (MS) in children manifests with a relapsing-remitting MS (RRMS) disease course. Acute relapses consist of new neurologic deficits persisting greater than 24 hours, in the absence of intercurrent illness, and occur with a higher frequency early in the disease as compared to adult-onset RRMS. Most pediatric patients with MS recover well from these early relapses, and cumulative physical disability is rare in the first 10 years of disease. Brainstem attacks, poor recovery from a single attack, and a higher frequency of attacks portend a greater likelihood of future disability. Although prospective pediatric-onset MS cohorts have been established in recent years, there remains very limited prospective data detailing the longer-term clinical outcome of pediatric-onset MS into adulthood. Whether the advent of MS therapies, and the largely off-label access to such therapies in pediatric MS, has improved prognosis is unknown. MS onset during the key formative academic years, concurrent with active cognitive maturation, is an important determinant of long-term outcome, and is discussed in detail in another article in this supplement. Finally, increasing recognition of pediatric MS worldwide, recent launch of phase III trials for new agents in the pediatric MS population, and the clear imperative to more fully appreciate health-related quality of life in pediatric MS through adulthood highlight the need for standardized, validated, and robust outcome measures.

    Abstract Objective: The aim of this study was to characterize key clinical manifestations of lysosomal acid lipase deficiency (LAL D) in children and adults. Methods: Investigators reviewed medical records of LAL D patients ages ≥5 years, extracted historical data, and obtained prospective laboratory and imaging data on living patients to develop a longitudinal dataset. Results: A total of 49 patients were enrolled; 48 had confirmed LAL D. Mean age at first disease-related abnormality was 9.0 years (range 0–42); mean age at diagnosis was 15.2 years (range 1–46). Twenty-nine (60%) were male patients, and 27 (56%) were <20 years of age at the time of consent/assent. Serum transaminases were elevated in most patients with 458 of 499 (92%) of alanine aminotransferase values and 265 of 448 (59%) of aspartate aminotransferase values above the upper limit of normal. Most patients had elevated low-density lipoprotein (64% patients) and total cholesterol (63%) at baseline despite most being on lipid-lowering therapies, and 44% had high-density lipoprotein levels below the lower limit of normal. More than half of the patients with liver biopsies (n = 31, mean age 13 years) had documented evidence of steatosis (87%) and/or fibrosis (52%). Imaging assessments revealed that the median liver volume was ∼1.15 multiples of normal (MN) and median spleen volume was ∼2.2 MN. Six (13%) patients had undergone a liver transplant (ages 9–43.5 years). Conclusion: This study provides the largest longitudinal case review of patients with LAL D and confirms that LAL D is predominantly a pediatric disease causing early and progressive hepatic dysfunction associated with dyslipidemia that often leads to liver failure and transplantation.

    The autopsy case of a 3-year 6-month-old boy with chordoma arising in the sacrococcygeal region is presented. The primary lesion of the sacrococcygeal area was unresectable and lung metastasis was detected. He was treated with multi-agent systemic chemotherapy and radiation therapy, but the tumor was less responsive to these therapies. He died about one year after first admission. An autopsy revealed a massive sacrococcygeal mass and metastasis in the thoracic and lumbar vertebrae, retroperitoneal and mediastinal lymph nodes, and also in the bilateral lungs and liver. Histologically, the tumor was composed of 'pink' cells and scattered 'physaliphorous' cells with a myxoid matrix. Sacrococcygeal chordoma in infancy is very rare. Our case showed a highly aggressive clinical course.

    Preprosthetic interventions in patients with aggressive forms of inflammatory papillary hyperplasia have historically involved surgery. These procedures often involve significant postoperative discomfort and morbidity. Additionally, some patients who present with dental phobias, aversions to surgery, or underlying systemic disease may not be amenable to this type of surgical intervention. In this report, a patient with severe inflammatory papillary hyperplasia and phobias regarding the dentist and dental surgery was treated nonsurgically, following strict adherence to a clinical protocol. The methodology involved greater patient comfort during treatment, encouraged positive reinforcement to visiting the dentist for recall appointments, and effectively eliminated the underlying inflammatory papillary hyperplasia, allowing for the successful fabrication of the definitive removable prostheses.

    This investigation examined the relation between developmental trajectories jointly estimated for social and physical aggression and adjustment problems at age 14. Teachers provided ratings of children's social and physical aggression in Grades 3, 4, 5, 6, and 7 for a sample of 255 children (131 girls, 21% African American, 52% European American, 21% Mexican American). Participants, parents, and teachers completed measures of the adolescent's adjustment to assess internalizing symptoms, rule-breaking behaviors, and borderline and narcissistic personality features. Results showed that membership in a high and rising trajectory group predicted rule-breaking behaviors and borderline personality features. Membership in a high desister group predicted internalizing symptoms, rule-breaking behaviors, and borderline and narcissistic personality features. The findings suggest that although low levels of social and physical aggression may not bode poorly for adjustment, individuals engaging in high levels of social and physical aggression in middle childhood may be at greatest risk for adolescent psychopathology, whether they increase or desist in their aggression through early adolescence.

    Examined the extent to which 359 mothers and 140 fathers of clinic-referred youth (ages 2 to 17) reported using corporal punishment and severe physical aggression when asked directly via intake screening questionnaires at a community mental health center; higher prevalence rates emerged compared to families in the general population. Clinic-referred parents reported greater use of corporal punishment for younger relative to older youth, sons relative to daughters, and by single relative to married mothers. In cases with reports from both parents, mothers used corporal punishment more frequently than fathers. Demographic factors were not linked to severe physical aggression, except for mothers' treatment of sons versus daughters. After controlling for demographic factors, maternal and paternal reports of child externalizing behavior accounted for significant variance in their own and their partner's use of corporal punishment, and in mothers' use of severe physical aggression.

    Objective To develop a method for profiling the collective populations targeted for recruitment by multiple clinical studies addressing the same medical condition using one eligibility feature each time. Methods Using a previously published database COMPACT as the backend, we designed a scalable method for visual aggregate analysis of clinical trial eligibility features. This method consists of four modules for eligibility feature frequency analysis, query builder, distribution analysis, and visualization, respectively. This method is capable of analyzing (1) frequently used qualitative and quantitative features for recruiting subjects for a selected medical condition, (2) distribution of study enrollment on consecutive value points or value intervals of each quantitative feature, and (3) distribution of studies on the boundary values, permissible value ranges, and value range widths of each feature. All analysis results were visualized using Google Charts API. Five recruited potential users assessed the usefulness of this method for identifying common patterns in any selected eligibility feature for clinical trial participant selection. Results We implemented this method as a Web-based analytical system called VITTA (Visual Analysis Tool of Clinical Study Target Populations). We illustrated the functionality of VITTA using two sample queries involving quantitative features BMI and HbA1c for conditions “hypertension” and “Type 2 diabetes”, respectively. The recruited potential users rated the user-perceived usefulness of VITTA with an average score of 86.4/100. Conclusions We contributed a novel aggregate analysis method to enable the interrogation of common patterns in quantitative eligibility criteria and the collective target populations of multiple related clinical studies. A larger-scale study is warranted to formally assess the usefulness of VITTA among clinical investigators and sponsors in various therapeutic areas. PMID:25615940

    2010-01-01

    Pediatric aggression is common in human societies, mainly presenting as impulsive aggression or predatory aggression. Numerous psychiatric disorders can contain aggression as a symptom, leading to difficulties in diagnosis and treatment. This review focuses on the biological systems that affect pediatric aggression. We review the hypothalamic-pituitary-adrenal (HPA) axis, the hypothalamic-pituitary-gonadal (HPG) axis, and the mechanisms by which these axes influence the body and mind of aggressive children and adolescents. Although this review focuses on the HPA and HPG axes, it is important to note that other biological systems have relationships with these two axes. Based on the results of the studies reviewed, elevated cortisol concentrations were associated with impulsive aggression, whereas, low levels of cortisol were associated with callous-unemotional traits similar to predatory aggression. Higher levels of dehydroepiandrosterone were correlated with higher levels of aggression as were higher levels of testosterone. However, there have been discrepancies in the results between various studies, indicating the need for more research on hormonal levels and pediatric aggression. In the future, hormonal levels may be useful in determining what treatments will work best for certain pediatric patients.

    Objective Overexpression of survivin has been reported in many human tumors. However, the clinicopathological features associated with survivin overexpression in cervical carcinoma remain controversial. Thus, the current meta-analysis was performed to assess the clinicopathological significance of survivin in cervical carcinoma. Methods PubMed, EMBASE, and Web of Science databases were searched for relevant studies published through November 1, 2015. A meta-analysis was performed to evaluate the association between survivin expression and clinicopathological outcome in cervical carcinoma. Results Eleven eligible studies with a total of 865 patients were included. Survivin overexpression was closely related to lymph node metastasis (odds ratio [OR] = 0.679, 95% confidence interval [CI]: 0.509–0.905, P = 0.008) but was not significantly associated with tumor FIGO stage (I+II vs. III+IV) (OR = 0.843, 95% CI: 0.626–1.137, P = 0.264), tumor grade (G1+G2 vs. G3) (OR = 0.913, 95% CI: 0.689–1.210, P = 0.527), tumor size (>4 vs. ≤4 cm) (OR = 0.825, 95% CI: 0.434–1.570, P = 0.559), or stromal involvement (OR = 0.820, 95% CI: 0.545–1.233, P = 0.340). The correlation between survivin expression and overall survival was evaluated among a total of 238 patients from three eligible studies. The pooled HR was 1.129 (95% CI: 0.597–1.661; P = 0.000), indicating that survivin expression was significantly associated with poor survival in cervical carcinoma. Conclusions Based on the current meta-analysis, survivin is strongly associated with lymph node metastasis and poor prognosis. Additionally, survivin is a novel clinicopathological marker of cervical carcinoma and thus may be a therapeutic target for cervical carcinoma. PMID:27764228

    Our aim was to develop a detailed clinical description of fatal familial insomnia in a large patient group with respect to the M129V genotype. Data on 41 German fatal familial insomnia patients were analyzed. Clinical features, 14-3-3 proteins in the cerebrospinal fluid, magnetic resonance imaging, positron emission tomography, single-photon emission computed tomography, polysomnography, and electroencephalography were studied. Age at disease onset, disease duration, and clinical syndrome varied depending on the codon 129 genotype. Because the sensitivity of the most diagnostic tests is low in fatal familial insomnia, detailed clinical investigation is extremely important. Polysomnography may help to support the diagnosis.

    Severe acute respiratory syndrome (SARS) is a newly emerged infectious disease with a significant morbidity and mortality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache, and dyspnoea. Older subjects may present without the typical febrile response. Common laboratory features include lymphopenia, thrombocytopenia, raised alanine transaminases, lactate dehydrogenase, and creatine kinase. The constellation of compatible clinical and laboratory findings, together with certain characteristic radiological features and lack of clinical response to broad spectrum antibiotics, should arouse suspicion of SARS. Measurement of serum RNA by real time reverse transcriptase-polymerase chain reaction technique has a detection rate of 75%–80% in the first week of the illness. PMID:15254300

    2015-07-01

    Richter syndrome (RS) or Richter transformation is the development of secondary aggressive lymphoma in the setting of underlying chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Most frequently CLL transforms into diffuse large B-cell lymphoma (DLBCL) (90%) and rarely (10%) into Hodgkin lymphoma, termed Hodgkin variant of Richter syndrome (HvRS). RS is generally characterized by an aggressive clinical course and poor prognosis. In recent years, major advances have been made in understanding genetic events which relate to the progression of CLL or transformation into RS. Better understanding of the molecular pathways has revealed that RS is not a single homogeneous entity. The majority of cases are clonally related to the original CLL clone, while a minority develop from an unrelated clone. This review summarizes new data relating to the molecular biology and the genetic/epigenetic changes occurring during Richter transformation, and also considers the clinical features and therapy for both DLBCL-RS and Hodgkin variant-RS.

    Opercular malformations are rare and complex brain malformations for which only very fragmented neuropathological descriptions have been reported. They are related to an abnormal development of both sylvian fissure and frontoparietal operculum. We report a retrospective clinical and MRI study of 11 patients presenting with opercular malformations. A congenital pseudobulbar syndrome was observed in six cases, various motor disorders in seven cases, mental retardation in six cases and epilepsy in four cases. The purpose of this study is to evaluate the main features of opercular malformations in children and to try to characterise this entity on the basis of its clinical features and MRI pattern.

    In this study we present novel feature engineering techniques that leverage the biomedical domain knowledge encoded in the Unified Medical Language System (UMLS) to improve machine-learning based clinical text classification. Critical steps in clinical text classification include identification of features and passages relevant to the classification task, and representation of clinical text to enable discrimination between documents of different classes. We developed novel information-theoretic techniques that utilize the taxonomical structure of the Unified Medical Language System (UMLS) to improve feature ranking, and we developed a semantic similarity measure that projects clinical text into a feature space that improves classification. We evaluated these methods on the 2008 Integrating Informatics with Biology and the Bedside (I2B2) obesity challenge. The methods we developed improve upon the results of this challenge’s top machine-learning based system, and may improve the performance of other machine-learning based clinical text classification systems.

    Background A new area of interest in the search for biomarkers for schizophrenia is the study of the acoustic parameters of speech called 'speech signal features'. Several of these features have been shown to be related to emotional responsiveness, a characteristic that is notably restricted in patients with schizophrenia, particularly those with prominent negative symptoms. Aim Assess the relationship of selected acoustic parameters of speech to the severity of clinical symptoms in patients with chronic schizophrenia and compare these characteristics between patients and matched healthy controls. Methods Ten speech signal features-six prosody features, formant bandwidth and amplitude, and two spectral features-were assessed using 15-minute speech samples obtained by smartphone from 26 inpatients with chronic schizophrenia (at enrollment and 1 week later) and from 30 healthy controls (at enrollment only). Clinical symptoms of the patients were also assessed at baseline and 1 week later using the Positive and Negative Syndrome Scale, the Scale for the Assessment of Negative Symptoms, and the Clinical Global Impression-Schizophrenia scale. Results In the patient group the symptoms were stable over the 1-week interval and the 1-week test-retest reliability of the 10 speech features was good (intraclass correlation coefficients [ICC] ranging from 0.55 to 0.88). Comparison of the speech features between patients and controls found no significant differences in the six prosody features or in the formant bandwidth and amplitude features, but the two spectral features were different: the Mel-frequency cepstral coefficient (MFCC) scores were significantly lower in the patient group than in the control group, and the linear prediction coding (LPC) scores were significantly higher in the patient group than in the control group.

    AIM: To evaluate the frequency, clinical and paraclinical features of hepatopulmonary syndrome (HPS) and to determine their predictive values in diagnosis of this syndrome in patients in Iran. METHODS: Fifty four cirrhotic patients underwent contrast enhanced echocardiography to detect intrapulmonary and intracardiac shunts by two cardiologists. Arterial blood oxygen, O2 gradient (A-a) and orthodoxy were measured by arterial blood gas (ABG) test. The patients positive for diagnostic criteria of HPS were defined as clinical HPS cases and those manifesting the intrapulmonary arterial dilation but no other criteria (arterial blood hypoxemia) were defined as lHPS cases. HPS frequency, sensitivity, positive and negative predictive values of clinical and paraclinical features were studied. RESULTS: Ten (18.5%) and seven (13%) cases had clinical and subclinical HPS, respectively. The most common etiology was hepatitis B. Dyspnea (100%) and cyanosis (90%) were the most prevalent clinical features. Dyspnea and clubbing were the most sensitive and specific clinical features respectively. No significant relationship was found between HPS and splenomegaly, ascites, edema, jaundice, oliguria, and collateral veins. HPS was more prevalent in hepatitis B. PaO2 < 70 and arterial-alveolar gradient had the highest sensitivity in HPS patients. Orthodoxy specificity was 100%. CONCLUSION: Clubbing with positive predictive value (PPV) of 75% and dyspnea with negative predictive value (NPV) of 75% are the best clinical factors in diagnosis of HPS syndrome. PaO2 < 70 and P (A-a) O2 > 30 and their sum, are the most valuable negative and positive predictive values in HPS patients. PMID:16610006

    Aggressivity is a common problem in the management of elderly patients with dementia. Medications currently used to diminish aggressive behaviour in dementia can have problematic side effects. We present a case and systematic review of the current knowledge about the use of cyproterone acetate to treat aggressivity (excluding hypersexuality related behaviours) in dementia. An 82-year-old man required psychiatric inpatient admission due to agitation and aggressivity and was diagnosed with Alzheimer's disease. After failed trials of atypical antipsychotics (quetiapine 100 mg/day and risperidone 1 mg/day), drugs for dementia (memantine 20 mg/day and rivastigmine 9 mg/day) and benzodiazepines (lorazepam 0.5-1 mg prn) he was started on cyproterone acetate titrated up to 50 mg twice daily. After two weeks he was calmer and did not express aggressivity. Two months later he was discharged to a community placement where he subsequently remained settled on cyproterone. We reviewed literature on the use of cyproterone in aggressivity (excluding hypersexuality) associated with dementia. We searched the main medical databases including articles in English, Spanish, French and Italian. Only one randomized double-blind trial was found, comparing cyproterone with haloperidol (n = 27). Cyproterone was more effective controlling aggressivity and had lower incidence of side effects. In the one uncontrolled naturalistic observational study identified (n = 19), cyproterone was associated with significant reductions in aggressivity without causing major side effects. Further literature was limited to theoretical discussions. Despite there being evidence to support our observations of a useful role for cyproterone in aggressivity in dementia, further studies are needed to establish the efficacy and safety of this therapeutic option.

    2013-09-01

    Morvan's Fibrillary Chorea (MFC) is a rare autoimmune disorder causally associated with auto-antibodies directed at the voltage-gated potassium channel (VGKC-Abs). It classically presents with sleep disturbances, neuromyotonia and dysautonomia. We aimed to systematically characterise the features of MFC by describing a patient and reviewing published literature. Case notes of 27 patients with MFC (one from our clinic and 26 from the literature) were reviewed and clinical data were extracted and analysed. We found that MFC mainly affects men (96%) and runs a subacute course over months. Neoplasia (56%), VGKC-Abs positivity (79%) and autoimmunity (41%) are frequent associations. Myokymia, insomnia and hyperhidrosis were almost universally described. Other autonomic features were present in 63% with the most common being cardiovascular and bowel disturbances. Clinical, radiological or electroencephalographical features of limbic encephalitis were present in 19% of patients. Outcome was fair with an overall recovery rate of 78%. All patients with malignancies underwent surgery. Immunotherapies including corticosteroids, intravenous immunoglobulins and plasma exchange were instituted in 22 patients and 19 (86%) responded. Of all symptomatic treatments tried, carbamazepine, phenytoin, sodium valproate, levetiracetam and niaprazine were found to be effective. The broad clinical spectrum of VGKC-Abs diseases can make early recognition of MFC difficult. Myokymia, insomnia and hyperhidrosis are invariably present. There may be abnormalities on cerebrospinal fluid testing and VGKC-Abs can occasionally be absent. Early initiation of immunotherapies and malignancy screening are important to prevent adverse outcomes in a condition that generally responds favourably to treatment.

    The comparative clinical and demographic features of neuromyelitis optica (NMO) are not well known. In this review we analyzed peer-reviewed publications for incidence and prevalence, clinical phenotypes, and demographic features of NMO. Population-based studies from Europe, South East and Southern Asia, the Caribbean, and Cuba suggest that the incidence and prevalence of NMO ranges from 0.05–0.4 and 0.52–4.4 per 100,000, respectively. Mean age at onset (32.6–45.7) and median time to first relapse (8–12 months) was similar. Most studies reported an excess of disease in women and a relapsing course, particularly in anti-aquaporin 4 antibody (anti AQP4-IgG)-positive patients. Ethnicity may have a bearing on disease phenotype and clinical outcome. Despite limitations inherent to the review process, themes noted in clinical and demographic features of NMO among different populations promote a more global understanding of NMO and strategies to address it.

    A dermatoscope is an important tool in a dermatologist's armamentarium as it can eliminate the need for a biopsy in a wide array of conditions. Porokeratosis was described by Mibelli and Respighi in 1893, as a disorder of keratinization which on the basis of distribution patterns was described as five clinical variants that portrayed a coronoid lamella on histopathology. We describe a case of asymptomatic, long-standing palmar and plantar pits, which on dermatoscopy showed features suggestive of porokeratosis, which was later reconfirmed by histopathologic sections. This report depicts diagnostic features of porokeratosis and obviates the need for invasive procedures for its diagnosis. PMID:27559506

  19. Clinical Features and Developing Risks of Saphenous Vein Thrombophlebitis

    PubMed Central

    2016-01-01

    We evaluated the clinical features and the risks of 14 patients with 14 limbs affected by saphenous vein thrombophlebitis from April 2007 to May 2013 and compared the results with patients undergoing operative repair of varicose veins (127 patients, 193 limbs) during the study period. The frequency of patients with a body mass index over 25 (78.6% vs. 35.3%, p = 0.0018), varicose change in the saphenous vein (78.6% vs. 6.2%, p <0.0001), and concurrent thrombosis in another vein (50.0% vs. 7.1%, p <0.0001) were all significantly higher than those of the patients under operative repair for varicose veins. These patients with clinical features above may be at an elevated risk of thrombophlebitis of the saphenous trunk. (This article is a translation of J Jpn Coll Angiol 2014; 54: 151–157).

    2002-01-01

    Clinical features on the first unexpected nerve gas terrorism using sarin (isopropyl methylphosphonofluoridate) on citizens in the city of Matsumoto is described. The nerve gas terrorism occurred at midnight on 27 June, 1994. About 600 people including residents and rescue staff were exposed to sarin gas. Fifty-eight victims were admitted to hospitals and seven died. Theoretically, sarin inhibits systemic acetylcholinesterase and damages all the autonomic transmission at the muscarinic and nicotinic acetylcholine receptor. Miosis was the most common finding in the affected people. In cases with severe poisoning, organophosphate may affect the central nervous system and cause cardiomyopathy. A few of the victims complained of arrhythmia and showed a decreased cardiac contraction. Abnormal electroencephalograms were recorded in two patients. The clinical features and follow-up studies are discussed with reference to the Tokyo subway terrorism and related articles.

    Pineal cysts (PCs) are benign and often asymptomatic lesions of the pineal region that are typically small and do not change in size over time. PCs appear as small, well circumscribed, unilocular masses that either reside within or completely replace the pineal gland. This article reviews and discusses the characteristic features of PCs-clinical, histological, and identifiable by various imaging modalities-which assist clinicians in narrowing the differential diagnosis for pineal lesions.

    Interstitial lung disease (ILD) is the most common extra-articular manifestations of rheumatoid arthritis (RA) in the lung. This study aimed to identify clinical features of RA-associated ILD (RA-ILD). Patients with RA were retrospectively enrolled and sub-classified as RA-ILD or RA without ILD based on high-resolution computed tomography imaging. Pulmonary function testing parameters and levels of RA-related biomarkers, tumour markers, and acute-phase proteins were compared between the two groups. Logistic regression model was used to assess the strength of association between RA-ILD and clinical features of interest. Receiver operating characteristic analysis was performed to assess potential predictive value of clinical features for detecting RA-ILD. Comparison analysis indicated that the percentage of predicted value of total lung capacity, inspiratory capacity, and diffusion capacity of the lung for carbon monoxide (DLCO) were reduced in patients with RA-ILD. Tumour markers CA15-3 and CA125 were increased in patients with RA-ILD. Logistic regression analysis revealed that decreased DLCO was related to the increased likelihood of RA-ILD (OR = 0.94, 95%CI = [0.91, 0.98]). The cut-off point at 52.95 percent of predicted value could sensitively discriminate RA patients with or without ILD. Our study suggested that DLCO value could be a useful tool for detecting ILD in patients with RA.

    Objectivea??To characterize clinical features of avian vacuolar myelinopathy (AVM) in American coots. Designa??Case-control study. Animalsa??26 AVM-affected American coots and 12 unaffected coots. Proceduresa??Complete physical, neurologic, hematologic, and plasma biochemical evaluations were performed. Affected coots received supportive care. All coots died or were euthanatized, and AVM status was confirmed via histopathologic findings. Resultsa??3 severely affected coots were euthanatized immediately after examination. Seventeen affected coots were found dead within 7 days of admission, but 5 affected coots survived > 21 days and had signs of clinical recovery. Abnormal physical examination findings appeared to be related to general debilitation. Ataxia (88%), decreased withdrawal reflexes (88%), proprioceptive deficits (81%), decreased vent responses (69%), beak or tongue weakness (42%), and head tremors (31%), as well as absent pupillary light responses (46%), anisocoria (15%), apparent blindness (4%), nystagmus (4%), and strabismus (4%) were detected. Few gross abnormalities were detected at necropsy, but histologically, all AVM-affected coots had severe vacuolation of white matter of the brain. None of the control coots had vacuolation. Conclusions and Clinical Relevancea??Although there was considerable variability in form and severity of clinical neurologic abnormalities, clinical signs common in AVM-affected birds were identified. Clinical recovery of some AVM-affected coots can occur when supportive care is administered. Until the etiology is identified, caution should be exercised when rehabilitating and releasing coots thought to be affected by AVM.

    Nemaline myopathy (NM) is a rare congenital myopathy of great heterogeneity, characterized by the presence of rods in the cytoplasm of muscle fibers. This study aimed to summarize and analyze retrospectively the clinicopathological features of 28 patients with NM. Among the 28 patients, 15 were classified as of the typical congenital type, manifested as lower- or four-limb weakness as the first symptom and slowly progressive course. Six patients were classified as of childhood onset type, with lower-limb weakness and progressive course. Seven patients were classified as of the adult onset type, with rapidly progressive course and obvious muscle atrophy. Patient's 1, 16 and 23 had rapid clinical progression. On follow up, the three patients showed respiratory failure. Limb weakness in all patients was proximal‑dominant. Hypotonia was observed in most patients. High arched feet were also observed as dysmorfic features. In all patients, the creatine kinase (CK) level was normal or mildly elevated, and electromyography revealed myogenic changes. Nemaline bodies were observed under a light microscope in more than half of the patients' muscle fibers, and especially in type I fibers. All patients showed fiber type I predominance and atrophy. Modified Gömöri trichrome staining showed characteristic purple‑colored rods. Muscle electron microscopy revealed the presence of high electron‑dense nemaline bodies around the nucleus, and of a disorganized myofibrillar apparatus, with broken myofilaments and irregular myofibrils and Z lines. The 28 patients with NM shared a number of clinical features, such as proximal limb weakness, reduced deep tendon reflex and dysmorfic features. Differences were also observed between the three types of patients, with regards to course progression, disease severity and respiratory failure. In conclusion, patients with NM showed great clinical heterogeneity. The diagnosis of NM was mainly based on the muscle biopsy. PMID:24788569

    Objectives Nodding syndrome is a devastating neurological disorder of uncertain aetiology affecting children in Africa. There is no diagnostic test, and risk factors and symptoms that would allow early diagnosis are poorly documented. This study aimed to describe the clinical, electrophysiological and brain imaging (MRI) features and complications of nodding syndrome in Ugandan children. Design Case series. Participants 22 children with nodding syndrome brought to Mulago National Referral Hospital for assessment. Outcome measures Clinical features, physical and functional disabilities, EEG and brain MRI findings and a staging system with a progressive development of symptoms and complications. Results The median age of symptom onset was 6 (range 4–10) years and median duration of symptoms was 8.5 (range 2–11) years. 16 of 22 families reported multiple affected children. Physical manifestations and complications included stunting, wasting, lip changes and gross physical deformities. The bone age was delayed by 2 (range 1–6) years. There was peripheral muscle wasting and progressive generalised wasting. Four children had nodding as the only seizure type; 18 in addition had myoclonic, absence and/or generalised tonic–clonic seizures developing 1–3 years after the onset of illness. Psychiatric manifestations included wandering, aggression, depression and disordered perception. Cognitive assessment in three children demonstrated profound impairment. The EEG was abnormal in all, suggesting symptomatic generalised epilepsy in the majority. There were different degrees of cortical and cerebellar atrophy on brain MRI, but no hippocampal changes. Five stages with worsening physical, EEG and brain imaging features were identified: a prodrome, the development of head nodding and cognitive decline, other seizure types, multiple complications and severe disability. Conclusions Nodding syndrome is a neurological disorder that may be characterised as probably

    Middle school is a critical yet understudied period of social behavioral risks and opportunities that may be particularly difficult for emerging adolescents with ADHD given their childhood social difficulties. Although childhood ADHD has been associated with increased aggression and peer relational difficulties, relatively few ADHD studies have examined social behavior beyond the elementary years, or examined aspects of positive (prosocial) behavior. In addition, social-cognitive problem solving has been implicated in ADHD; however, its longitudinal impact on prosocial and aggressive behavior is unclear. The current study examined how middle school students with clinically elevated ADHD symptoms differ from their non-ADHD peers on baseline (sixth grade) and age-related changes in prosocial and aggressive behavior, and the extent to which social-cognitive problem solving strategies mediate these relations. Emerging adolescents with (n = 178) and without (n = 3,806) clinically elevated, teacher-reported ADHD inattentive and hyperactive/impulsive symptoms were compared longitudinally across sixth through eighth grades using parallel process latent growth curve modeling, accounting for student demographic characteristics, ODD symptoms, deviant peer association, school climate, and parental monitoring. Sixth graders with elevated ADHD symptoms engaged in somewhat fewer prosocial behaviors (d= −0.44) and more aggressive behavior (d= 0.20) relative to their peers. These small social behavioral deficits decreased but were not normalized across the middle school years. Contrary to hypotheses, social-cognitive problem solving was not impaired in the ADHD group, and did not mediate the association between ADHD and social behavior during the middle school years. ADHD and social-cognitive problem solving contributed independently to social behavior, both in sixth grade and across the middle school years; the influence of social-cognitive problem solving on social behavior was

    This review focuses on summarizing 2 pivotal articles in the clinical and pathophysiologic understanding of hemicrania continua (HC). The first article, a functional imaging project,identifies both the dorsal rostral pons (a region associated with the generation of migraines) and the posterior hypothalamus(a region associated with the generation of cluster and short-lasting unilateral neuralgiform headache with conjunctival injection and tearing [SUNCT]) as active during HC. The second article is a summary of the clinical features seen in a prospective cohort of HC patients that carry significant diagnostic implications. In particular, they identify a wider range of autonomic signs than what is currently included in the International Headache Society criteria (including an absence of autonomic signs in a small percentage of patients), a high frequency of migrainous features, and the presence of aggravation and/or restlessness during attacks. Wide variations in exacerbation length, frequency, pain description, and pain location (including side-switching pain) are also noted. Thus, a case is made for widening and modifying the clinical diagnostic criteria used to identify patients with HC.

    Background: Neuromyelitis optica spectrum disorder (NMOSD) was long believed to be an aggressive form of multiple sclerosis (MS). This study aimed to describe the clinical features of patients with MS and NMOSD to assist in differential diagnoses in clinical practice. Methods: Data including the patients’ serum and cerebrospinal fluid (CSF) tests, image findings, and clinical information from 175 patients with MS or NMOSD at Xuanwu Hospital, Capital Medical University from November 2012 to May 2014 were collected and analyzed retrospectively. An enzyme-linked immunosorbent assay was performed to detect the myelin oligodendrocyte glycoprotein (MOG) autoantibodies in CSF and serum. Cell-based assays were used to detect aquaporin-4-antibody (AQP4-Ab). The Chi-square test was used to compare the categorical variables. Wilcoxon rank sum test was performed to analyze the continuous variables. Results: Totally 85 MS patients (49%) and 90 NMOSD patients (51%) were enrolled, including 124 (71%) women and 51 (29%) men. Fewer MS patients (6%) had autoimmune diseases compared to NMOSD (19%) (χ2 = 6.9, P < 0.01). Patients with NMOSD had higher Expanded Disability Status Scale scores (3.5 [3]) than MS group (2 [2]) (Z = −3.69, P < 0.01). The CSF levels of white cell count and protein in both two groups were slightly elevated than the normal range, without significant difference between each other. Positivity of serum AQP4-Ab in NMOSD patients was higher than that in MS patients (MS: 0, NMOSD: 67%; χ2 = 63.9, P < 0.01). Oligoclonal bands in CSF among NMOSD patients were remarkably lower than that among MS (MS: 59%, NMOSD: 20%; χ2 = 25.7, P < 0.01). No significant difference of MOG autoantibodies was found between the two groups. Conclusion: The different CSF features combined with clinical, magnetic resonance imaging, and serum characteristics between Chinese patients with MS and NMOSD could assist in the differential diagnosis.

    Heart failure-induced cardiovascular morbidity and mortality constitute a major health problem worldwide and result from diverse pathogeneses, including coronary artery disease, nonischemic cardiomyopathies, and arrhythmias. Assessment of cardiovascular performance is important for early diagnosis and accurate management of patients at risk of heart failure. During the past decade, cardiovascular magnetic resonance myocardial feature tracking has emerged as a useful tool for the quantitative evaluation of cardiovascular function. The method allows quantification of biatrial and biventricular mechanics from measures of deformation: strain, torsion, and dyssynchrony. The purpose of this article is to review the basic principles, clinical applications, accuracy, and reproducibility of cardiovascular magnetic resonance myocardial feature tracking, highlighting the prognostic implications. It will also provide an outlook on how this field might evolve in the future. PMID:27009468

    Dacryocystitis-related orbital cellulitis is a relatively rare condition, and large case series of this clinical entity have been reported. This study was undertaken to identify a larger cohort of patients with this ailment, with the intent of defining its clinical and microbiologic features. Case logs from four institutions were reviewed to identify patients that suffered from dacryocystitis-related orbital cellulitis. A retrospective chart review was then performed to identify clinical features, management strategies, microbiologic features, and outcomes. A dedicated statistical software package was utilized to identify correlations between these variables. 13 patients (7 females, 6 males; mean age = 57.2 years, range = 7-89 years) were identified. One patient carried a diagnosis of immunosuppressive disease. All patients underwent emergent surgical drainage and received intravenous antibiotics. Primary acquired nasolacrimal duct obstruction was found to be the underlying etiology in nine cases (69.2%), whereas four patients suffered from specific causes of their obstructions. An average of 1.07 organisms/patient (standard deviation = 0.49 organisms/patient) were recovered from microbiologic cultures, and Gram-positive bacteria represented the majority of cultured organisms. All patients experienced either stable or improved vision upon discharge. The relationships between a specific etiology and the possibility of vision loss or the number of organisms cultured, between the number of organisms cultured and vision loss, and immunosuppression and vision loss or the number of organisms cultured were all not statistically significant (p > 0.05). Dacryocystitis-related orbital cellulitis most commonly occurs in adult patients who do not carry immunosuppressive diagnoses and suffer from primary obstructions. Multiple microbiologic species may cause this problem, although Gram-positive organisms are most common. With appropriate management, stable or improved vision

    The aims of the current study were to assess the clinical features of allergic rhinitis (AR) in children in Shanghai. Serum-specific IgE (sIgE) tests were performed on samples from patients with AR symptoms from January 2011 to December 2014. A disease-related questionnaire was completed after AR diagnosis. The allergen profile and clinical features of AR were analyzed. In total, 2713 AR patients were enrolled in this study. Dermatophagoides pteronyssinus was found to be the most common offending allergen in the study population. With increasing age, the prevalence of sIgE against inhalant allergens was significantly increased; however, the opposite trend was observed for food allergens. Additionally, the proportion of children with high levels of sIgE against D. pteronyssinus increased with age. Of the AR cases, 8.6% were classified as intermittent mild, 4.2% as persistent mild, 40.5% as intermittent moderate-severe, and 46.7% as persistent moderate-severe. A family history of allergies and a patient history of allergies within 6 months of birth were significantly associated with the duration and severity of AR symptoms. The occurrence of co-morbidities, such as allergic conjunctivitis, cough, and asthma, gradually increased from intermittent mild, persistent mild, and intermittent moderate-severe to persistent moderate-severe. The most frequently used drugs were topical corticosteroids and oral antihistamines, which were used by 86.7 and 79.0% of patients, respectively. These results confirm the adequacy of the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines for classifying AR patients, and advance the understanding of clinical features of AR in children in Shanghai, China.

    Genetic cardiac diseases related to potassium channelopathies are a group of relatively rare syndromes that includes long QT syndrome, short QT syndrome, Brugada syndrome, and early repolarization syndrome. Patients with these syndromes share a propensity for the development of life-threatening ventricular arrhythmias in the absence of significant cardiac structural abnormalities. Familial atrial fibrillation has also been associated with potassium channel dysfunction but differs from the other syndromes by being a rare cause of a common condition. This article focuses on the clinical features, diagnosis, and management of these syndromes. PMID:27261827

    2013-08-01

    Migraine-associated vertigo (MAV) is proposed as a new clinical entity on the basis of the assumption that the typical migraine and vertigo or dizziness have a common pathophysiology. Some of the patients with recurrent vertigo syndromes with unknown pathology may have MAV. We performed a retrospective study to clarify the clinical characteristics of MAV in the Japanese population. The following were considered as diagnostic criteria: (1) recurrent vestibular symptoms, (2) migraine headache as defined by the International Headache Society (IHS) criteria, (3) at least one instance of synchronization of a vertiginous attack with a migraine headache, (4) no associated unilateral hearing loss, and (5) absence of other diseases that may have caused vertiginous attacks. Of 552 patients with dizziness or vertigo, 46 (8.3%) were diagnosed as having MAV. A typical feature of this clinical entity is that migraine occurs before the onset of vertigo in women aged 30-40 years. Usually the attacks occur once in a year for 1 to 10 years. An attack lasts for 1-24 h and presents as vertigo and unsteadiness with simultaneous headache. The presence of hearing loss presents an important clinical dilemma. Whether the condition in patients experiencing hearing loss should be defined as MAV or not is still a matter for discussion.

    The clinical and morphologic features of hypertrophic cardiomyopathy in 20 patients recognized as having cardiac disease in the first year of life are described. Fourteen of these 20 infants were initially suspected of having heart disease solely because a heart murmur was identified. However, the infants showed a variety of clinical findings, including signs of marked congestive heart failure (in the presence of nondilated ventricular cavities and normal or increased left ventricular contractility) and substantial cardiac enlargement on chest radiograph. Other findings were markedly different from those usually present in older children and adults with hypertrophic cardiomyopathy (e.g., right ventricular hypertrophy on the ECG and cyanosis). Consequently, in 14 infants, the initial clinical diagnosis was congenital cardiac malformation other than hypertrophic cardiomyopathy. The clinical course was variable in these patients, but the onset of marked congestive heart failure in the first year of life appeared to be an unfavorable prognostic sign; nine of the 11 infants with congestive heart failure died within the first year of life. In infants with hypertrophic cardiomyopathy, unlike older children and adults with this condition, sudden death was less common (two patients) than death due to progressive congestive heart failure.

    and supportive treatment were 40.0, 35.0, 9.0 and 7.5 months, respectively. For the 173 SBA patients with follow-up data, treatment, age and distant metastasis were important prognostic factors; 149 of 173 SBA patients received only surgery, and the depth of tumor invasion, lymph node metastasis and surgical approach were important prognostic factors. Adjuvant chemotherapy had not provided significant benefit to prolong OS in patients with adenocarcinoma. The incidence of small intestine primary malignant tumors is very low, and it is difficult to diagnose. The patients should be aggressively treated and regularly followed up with related clinical and pathological features. Currently, surgery is the most effective treatment, and the role of chemotherapy needs further large-scale clinical studies.

    Livedo vasculopathy (LV) is a chronic cutaneous disorder characterised by recurrent, painful ulceration ending in stellate scars. We have conducted a retrospective study of clinical features and treatment response of LV in 24 Chinese patients. LV occurred more frequently in women (male:female ratio  1:3). The peak age at onset of disease ranged from 14 to 20 years, younger than previously published data. 87.5% of the patients (21/24) showed significant summer exacerbation with ulcer formation. Out of 24 patients tested, 14 (58.3%) had positive antiphospholipid antibodies. Ten out of 14 patients (71.4%) were tested to be hypersensitive to multivalent insect antigens. Combinative anti-inflammatory therapy with steroids, tetracycline and Tripterygium glycosides plus antiplatelet/profibrinolytic drugs promoted quick healing of ulcer and reduce recurrence. The younger age of disease presentation and significant summer exacerbation are 2 novel clinical features observed in this study. These findings suggest that apart from procoagulation other risk factors may contribute significantly to the pathogenesis of LV. Although antiplatelet/profibrinolytic drugs are deemed as a first line therapy for LV, anti-inflammatory medications such as steroids, tetracycline and Tripterygium glycosides, from our experiences, are indispensable, especially for acute, ulcerative stage of disease.

    There has been increasing awareness of the incidence and potential long-term consequences of mild traumatic brain injury (mTBI) in children and young adults. While parents, school systems, and athletic programs are clamoring for evidence-based guidelines, the field remains primitive in understanding the factors resulting in a spectrum of individual outcomes, most of which are complete, but some of which are not. In this article, we discuss the definition, epidemiology, clinical presentation, course, and outcomes of mTBI, with a focus on the pediatric population as the context for reviewing the mechanisms and pathophysiology mediating, and biomarkers reflective of, more significant concussion-induced brain injury. Our goal is to present a general overview of the features of mTBI in the pediatric population in order to provide a conceptual model for pediatricians and pediatric subspecialists. This model emphasizes the importance of establishing actionable, noninvasive biomarkers that are reflective of brain injury and that may identify those pediatric patients who can benefit from earlier and more aggressive interventions. We will focus on the specific features of mTBI in pediatric patients; although given the relative lack of research in the pediatric population, we will also extrapolate from research on adults.

    Anti-N-methyl D-aspartate (NMDA) receptor encephalitis is the most common type of encephalitis in the spectrum of autoimmune encephalitis defined by antibodies targeting neuronal surface antigens. In the present study, the clinical spectrum of this disease is presented using instructive cases in correlation with the anti-NMDA receptor antibody titers in the cerebrospinal fluid (CSF) and serum. A total of 7 female patients admitted to the hospital of Hannover Medical School (Hannover, Germany) between 2008 and 2014 were diagnosed with anti-NMDA receptor encephalitis. Among these patients, 3 cases were selected to illustrate the range of similar and distinct clinical features across the spectrum of the disease and to compare anti-NMDA antibody levels throughout the disease course. All patients received immunosuppressive treatment with methylprednisolone, intravenous immunoglobulin and/or plasmapheresis, followed in the majority of patients by second-line therapy with rituximab and cyclophosphamide. The disease course correlated with NMDA receptor antibody titers, and to a greater extent with the ratio between antibody titer and protein concentration. A favorable clinical outcome with a modified Rankin Scale (mRS) score of ≤1 was achieved in 4 patients, 1 patient had an mRS score of 2 after 3 months of observation only, whereas 2 patients remained severely impaired (mRS score 4). Early and aggressive immunosuppressive treatment appears to support a good clinical outcome; however, the clinical signs and symptoms differ distinctively and treatment decisions have to be made on an individual basis.

    Keratocystic odontogenic tumour (KCOT) previously known as odontogenic keratocyst was recently classified as a benign lesion characterized by an infiltrating pattern, local aggressiveness with the propensity to recurrence. It is thought to arise from the dental lamina. Pain is usually not associated with KCOT until swelling occurs, and it commonly affects the posterior mandible. Multiple KCOT are associated with nevoid basal cell carcinoma syndrome. This study reports an aggressive case of KCOT with destruction of the osseous tissue of the mandible, accentuated face asymmetry, dysphagia and dysphonia. It was managed with a defined protocol which entailed diagnosis, treatment with enucleation along with peripheral ostectomy and rehabilitation. A long-term follow-up schedule was provided to the patient to observe the recurrence behaviour of this cyst. In postoperative phase, no complication was noticed regarding wound healing and recurrence. PMID:24964453

    Histopathological features of transplanted kidneys which gradually lose graft function have been traditionally reported with the term of chronic rejection (CR). In 1997 Banff's classification indicated the adoption of a new term for all these histological features, namely Chronic allograft nephropathy (CAN), recommending that the presence of morphological aspects suggestive of chronic rejection, such as chronic transplant glomerulopathy (CTG) and proliferative endoarteritis (PE), has to be specified. On the basis of these criteria we reviewed the renal biopsies of 92 patients who underwent kidney transplantation from 1999 to 2002. In all cases the biopsy had been performed 6 months after organ transplantation. In 30 of the 92 patients CTG and/or PE was evident supporting a diagnosis of CR; on the contrary, in 11 of the 92 patients the final diagnosis based on histological evidence was that of CAN. Clinical and laboratory tests revealed that the presence of proteinuria in patients with CR at the time of diagnosis was the single statistically significant difference between these two groups. In 7 of the 32 patients where the diagnosis of CR was based on the presence of early features of CTG, the treatment with ACE-I induced complete remission of the proteinuria. Cyclosporine-induced arteriolopathy (CSA) represents an additional histological finding which has been associated with graft loss in the transplanted kidney. The observation of arteriolopathy, similar to CSA in patients who did not receive calcineurine inhibitors, suggests some caution in the use of this diagnostic criteria.

    Background Median cleft lip is a rare anomaly consisting of a midline vertical cleft through the upper lip. It can also involve the premaxillary bone, the nasal septum, and the central nervous system. In our current report, we present the clinical features of 6 patients with a median cleft lip and their surgical management according to the accompanying anomalies. Methods From December 2010 to January 2014, 6 patients with a median cleft lip were reviewed. Five of these cases underwent surgical correction; alveolar bone grafting was performed in a patient with a median alveolar cleft. The surgical technique included inverted-U excision of the upper lip and repair of the orbicularis oris muscle. The mean follow-up period was 20.4 months (range, 7.4–44.0 months). Results The study patients presented various anomalous features. Five patients received surgical correction, 4 with repair of the median cleft lip, and one with iliac bone grafting for median alveolar cleft. A patient with basal sphenoethmoidal meningocele was managed with transoral endoscopic surgery for repair of the meningocele. Successful surgical repair was achieved in all cases with no postoperative complications. Conclusions Relatively mild forms of median cleft lip can be corrected with inverted-U excision with good aesthetic outcomes. In addition, there is a broad spectrum of clinical features and various anomalies, such as nasal deformity, alveolar cleft, and short upper frenulum, which require close evaluation. The timing of the operation should be decided considering the presence of other anomalies that can threaten patient survival. PMID:27218021

    Background: The clinical behavior and management of poorly differentiated thyroid carcinoma (PDTC) are very different from papillary thyroid carcinoma (PTC). By comparing the clinical and ultrasonographic features between the two tumors, we proposed to provide more possibilities for recognizing PDTC before treatment. Methods: The data of 13 PDTCs and 39 age- and gender-matched PTCs in Peking Union Medical College Hospital between December 2003 and September 2013 were retrospectively reviewed. The clinical and ultrasonic features between the two groups were compared. Results: The frequencies of family history of carcinoma, complication with other thyroid lesions, lymph node metastases, recurrent laryngeal nerve injuries, and distant metastases were higher in PDTCs (30.8%, 61.6%, 69.2%, 23.1%, and 46.2%, respectively) than those in PTCs (2.6%, 23.1%, 25.6%, 2.6%, and 2.6%, respectively) (P < 0.05). The mortality rate of PDTCs was greatly higher than PTCs (P < 0.01). Conventional ultrasound showed that the size of PDTCs was larger than that of PTCs (3.1 ± 1.9 cm vs. 1.7 ± 1.0 cm). Clear margins and rich and/or irregular blood flow were found in 92.3% of PDTCs, which differed substantially from PTCs (51.7% and 53.8%, respectively) (P < 0.05). Conclusions: PDTC is more aggressive and its mortality rate is higher than PTCs. Accordingly, more attention should be given to suspicious thyroid cancer nodules that show large size, regular shape, and rich blood flow signals on ultrasound to exclude the possibility of PDTCs.

    This retrospective descriptive study was conducted at Queen Sirikit National Institute of Child Health (QSNICH), Bangkok, Thailand to describe the clinical features of gastrointestinal salmonellosis in children. The medical records of 134 patients admitted to QSNICH in 2009 who had a positive stool culture for Salmonella spp were reviewed. Demographic, clinical, laboratory, treatment, culture and antimicrobial sensitivity data were collected and analyzed. The mean age of the patients was 22.9 months (range 0.5 to 158 months); 76.9% were < 2 years old. The male to female ratio was 1.5:1. Salmonella B was most commonly found serogroup (47%). The common clinical manifestations included diarrhea (99.3%), fever (93.3%), dehydration (64.9%) and nausea/vomiting (48.5%). Most of the Salmonella isolates were sensitive to a fluoroquinolone and many were sensitive to Cotrimoxazole, but few were sensitive to ampicillin. There were no significant differences in the clinical manifestations and drug sensitivities of the different Salmonella serogroups, except convulsions were more common in Salmonella E infected patients (p = 0.04) and more Salmonella C isolates were sensitive to ampicillin (p = 0.04). There was no significant correlation between clinical course and antimicrobial treatment, except the duration of diarrhea was significantly longer in patients who received antimicrobial treatment (mean 6.1, SD 4.7 days vs mean 4.2, SD 2.1 days) (p = 0.03). Three patients had Salmonella bacteremia. Three patients died but not directly due to Salmonella infection.

    Overexpression of class III β-tubulin (TUBB3), a factor that confers dynamic properties to microtubules, is a candidate biomarker for resistance to microtubule-targeting chemotherapeutics in breast and other types of solid cancer. Discrepant results from previous studies, with respect to the association of TUBB3 expression levels with breast cancer phenotype and patient prognosis, prompted the present study to investigate TUBB3 expression in a large cohort of breast cancer cases, with available clinical follow-up data. A preexisting breast cancer prognosis tissue microarray, containing a single 0.6 mm tissue core from each of 2,197 individual patients with breast cancer, was analyzed for TUBB3 expression by immunohistochemistry. The results of the present study revealed that TUBB3 expression was less frequent in lobular breast cancer cases (34%), compared with that of cancer cases of alternative histologies, including breast cancer of no special type (60%; P<0.0001). High TUBB3 positivity was associated with high tumor grade (P<0.0001), negativity for estrogen (P<0.0001) and progesterone receptors (P<0.004), as well as the presence of human epidermal growth factor 2 amplification (P<0.0001) and a triple-negative phenotype (P<0.0001). TUBB3 overexpression was additionally associated with reduced patient survival if all breast cancer cases of any histology were jointly analyzed (P=0.0088); however this link was not evident in the subset of breast cancer cases of no special type, or in a multivariate analysis including the established prognostic factors of tumor stage, grade and nodal stage. In conclusion, the present study demonstrated that TUBB3 overexpression was associated with adverse features of breast cancer, and that TUBB3 may possess a distinct role in lobular breast cancer cases, compared with alternative histological subtypes. The results of the present study do not support a clinically relevant role for TUBB3 as a prognostic marker in breast cancer. PMID

    Background & Aims: Inflammatory bowel disease is thought to be rare in Libya. The aim is to determine the prevalence of juvenile onset inflammatory bowel disease in Libya. Setting: Al-Fateh childrens' hospital, Benghazi, Libya. Methods: This is a retrospective study of all cases diagnosed over 10 years (1997–2006) with either ulcerative colitis, Crohn's disease or indeterminate colitis. Inclusion criteria were age <15 years at time of presentation who were resident in the eastern part of the country and who diagnosed with inflammatory bowel disease. Clinical features were outlined using a proforma. Results: Sixteen cases were diagnosed with inflammatory bowel disease, of whom 11 were males (M:F ratio of 1.5:1). The prevalence and incidence rates in the year 2006 were 3.6 and 0.9 per 100,000 children, respectively. The incidence rate increased from 0.2 in 2002 to 0.9 in 2006 (Z score of 39.87, p= 0.00). The age at presentation ranged from 5 months to 14 years. Nine had Crohn's disease (6 males) and 6 had ulcerative colitis (4 males). One patient had indeterminate colitis. The most common clinical features were diarrhea in 10 (62.5%), abdominal pain, anorexia and weight loss in 9 (56.2%), anemia in 7 (43.75%) and vomiting in 6 (37%). Ileopancolitis was found in 3 patients whereas 6 patients had ileocecal disease. Conclusions: Childhood inflammatory bowel disease in this population is not so rare and it is increasing. The clinical pattern is similar to that reported by others. PMID:21483512

    2010-01-01

    This article provides the reader with an overview and up-date of clinical features, specific cardiac disorders and prognosis of cardioembolic stroke. Cardioembolic stroke accounts for 14-30% of ischemic strokes and, in general, is a severe condition; patients with cardioembolic infarction are prone to early and long-term stroke recurrence, although recurrences may be preventable by appropriate treatment during the acute phase and strict control at follow-up. Certain clinical features are suggestive of cardioembolic infarction, including sudden onset to maximal deficit, decreased level of consciousness at onset, Wernicke’s aphasia or global aphasia without hemiparesis, a Valsalva manoeuvre at the time of stroke onset, and co-occurrence of cerebral and systemic emboli. Lacunar clinical presentations, a lacunar infarct and especially multiple lacunar infarcts, make cardioembolic origin unlikely. The more common high risk cardioembolic conditions are atrial fibrillation, recent myocardial infarction, mechanical prosthetic valve, dilated myocardiopathy, and mitral rheumatic stenosis. Transthoracic and transesophageal echocardiogram can disclose structural heart diseases. Paroxysmal atrial dysrhyhtmia can be detected by Holter monitoring. In-hospital mortality in cardioembolic stroke (27.3%, in our series) is the highest as compared with other subtypes of cerebral infarction. In our experience, in-hospital mortality in patients with early embolic recurrence (within the first 7 days) was 77%. Patients with alcohol abuse, hypertension, valvular heart disease, nausea and vomiting, and previous cerebral infarction are at increased risk of early recurrent systemic embolization. Secondary prevention with anticoagulants should be started immediately if possible in patients at high risk for recurrent cardioembolic stroke in which contraindications, such as falls, poor compliance, uncontrolled epilepsy or gastrointestinal bleeding are absent.

    BACKGROUND Cerebral hemorrhage is common in patients with cancer, but the clinical features and pathogenesis of liver cancer patients with cerebral hemorrhage are not well known. MATERIAL AND METHODS Liver cancer patients who developed cerebral hemorrhage were recruited from the First Affiliated Hospital of Guangxi Medical University between January 2003 and December 2014. We retrospectively analyzed clinical presentations, results of laboratory tests, and imaging examinations. The clinical features and pathogenesis were summarized. RESULTS Among 11133 patients with liver cancer, 9 patients (0.08%), including 3 females and 6 males met the inclusion criteria. The age range was 48-73 years and the average age was 61.67±8.97 years. Five patients did not have traditional hemorrhage risk factors and 4s had the risk factors; however, all had developed hepatocellular carcinoma, and 3 had developed metastasis. All 9 patients showed elevated tumor markers: an increased AFP level was detected in 6 patients, coagulation dysfunctions in 8 patients, and abnormal liver functions in 6 patients. Five patients had developed cerebral hemorrhagic lesions in the lobes of their brains, while hemorrhagic lesions in the basal ganglia occurred in 3 patients and in the brainstem in only 1 patient. Four patients had clear consciousness, while 5 patients were in coma and showed poor prognosis. CONCLUSIONS Patients who have liver cancer complicated with cerebral hemorrhage usually lack traditional risk factors of cerebral hemorrhage. The site of cerebral hemorrhage is often detected in the lobes of the brain. Coagulation dysfunctions might be the main pathogenesis of liver cancer complicated with cerebral hemorrhage.

    Polymorphous low-grade adenocarcinoma, also known as terminal duct or lobular carcinoma, was first described in two clinical case series in 1983. Before that time most of these neoplasms were diagnosed as benign salivary gland neoplasms including pleomorphic adenomas, variants of monomorphic adenomas, or salivary malignant conditions including malignant pleomorphic adenomas, adenoid cystic carcinomas, and adenocarcinoma not otherwise stated. This neoplasm with few exceptions originates in minor salivary gland tissue of the posterior hard and soft palates or buccal mucosa. It is characteristically slow to enlarge; clinical reports show the neoplasm present for many years before diagnosis. We have evaluated the clinical and microscopic features of 15 cases from the archives of The University of Iowa Surgical Oral Pathology Laboratory and added these to published case reports. A total of 204 cases were evaluated with a female/male ratio of almost 2/1. Forty-nine percent originated in palatal mucosa. Polymorphous low-grade adenocarcinomas arising from pleomorphic adenomas or de novo have been reported within major salivary glands and outside the oral cavity. A 17% recurrence rate was found with a regional metastasis rate of 9%. Five cases had multiple recurrences, and 13 recurrences were at or beyond 5 years after the initial diagnosis. Regional node metastases were identified at the time of initial treatment or at the time of recurrence in 9% of cases in which follow-up data were specified.

In order to analyze features of CMP clinical register, ClinicalTrials.gov register database were comprehensively retrieved in this study. Included clinical trials were input one item after another using EXCEL. A final of 348 CMP clinical trials were included. Results showed that China occupied the first place in CMP clinical register, followed by USA. CMP clinical trials, sponsored mainly by colleges/universities and hospitals, mostly covered interventional studies on evaluating safety/effectiveness of CMP. The proportions of studies, sponsored by mainland China and companies, recruitment trials and multi-center clinical trials in interventional trials were increasing. The proportions of studies sponsored by Hong Kong and Taiwan, research completed trials, unclear research status, phase III clinical trials, and published research trials in interventional trials were decreasing. Published ratios of CMP clinical trials were quite low. There were more missing types and higher proportions in trial register information.

    Background and objective Osteogenesis imperfecta (OI) comprises a group of disorders principally affecting type I collagen which result in increased bone fragility. Children with severe OI suffer recurrent fractures, resulting in severe deformity and growth stunting in many cases, with loss of independent ambulation by the teenage years in over 50% of cases. Recently, cyclical intravenous treatment with pamidronate has proven of benefit to children with severe forms of OI. This article aims to describle clinical features and laboratory manifestations of patient with OI and evaluate outcome of bisphosphonate management. Methods Clinical features, biochemical finding, and management outcome of 104 cases were study. The patients were classified into four major subtypes of Sillience et al. 1979. Patients with severe types were treatment with pamidronate (Aredia) used Rauch protocol 2003. Results Now we have 196 patients (87 females and 109 males) but we studied focus on 104 patients from 98 families (60 males, 44 females) onset at 2.1±3.0 years (median 0.35) with the average fracture bone of 5.9±4.4 times. In there, 17% type I, 8% type II, 63% type III, and 12% type IV. Clinical features include of intrauterine fracture visible on ultrasound 35%, bone deformation after birth 68%, triangle face 76%, long bone deformation 91%, chest deformation 46%, scoliosis 27%, short status 90%, blue sclera 83%, dentinogenesis imperfecta 20%, hearing loss 6%. Thirty patients have been treated with pamidronate at 3.2±3.7 years (4 months to 8 years) during 13±0.8 months (6-30 months). Fourteen patients had fracture bone after 6 months of treatment but no patients had fracture bone after 12 months. Seven patients had been treatment after 1.6±0.5 years, BMD increase from 0.39±0.311 to 0.79±0.105 g/cm2 (P<0.05). One patient had fever reaction after first pamidronate infusion but controlled with standard antipyretic therapy, and do not recur in later treatments. Conclusions OI has

    Objective: To evaluate clinical features, complications, visual outcomes and treatment modalities in patients clinically diagnosed with herpetic anterior uveitis (AU). Materials and Methods: We retrospectively reviewed the medical records of 67 patients seen at the Umraniye Training and Research Hospital, Ophthalmology Clinic, Uveitis and Cornea Department from January 2009 to June 2013. Results: Thirty-seven patients (55.2%) were female and 30 (44.7%) patients were male. The average follow-up period was 12.9 ± 10.6 months (range: 1-45 months). The most common ocular findings were granulomatous keratic precipitates (KPs) (82.2%), corneal involvement (62.6%), iris atrophy (41.7%) and transient elevated intraocular pressure (IOP) (40.2%). Recurrences were observed in 46.2% of the eyes and the median recurrence rate was 1.0 during the follow-up period. Topical steroids and oral antiviral (acyclovir) therapy were applied to all patients during active episodes. Long-term oral acyclovir was used in 29.8% of the patients. Recurrence rates were significantly lower in patients who used oral acyclovir for more than 6 months, whereas complications rates and final visual acuity did not show any difference between groups. Final visual acuity was better than 20/40 in 61.1% of eyes, and visual impairment was due to corneal scarring or cataract formation. Conclusion: Herpetic AU can present with or without corneal involvement. Granulomatous KPs, iris atrophy and elevated IOP are important clinical findings for the diagnosis of cases without corneal involvement. Long-term oral acyclovir treatment (more than 6 months) and is important to decrease recurrence rates and possible complications. Visual prognosis is favorable in cases without corneal scarring.

    The spectrum of somatic mutation of the most aggressive forms of neuroblastoma is not completely determined. We sought to identify potential cancer drivers in clinically aggressive neuroblastoma. Whole exome sequencing was conducted on 17 germline and tumor DNA samples from high-risk patients with adverse events within 36 months from diagnosis (HR-Event3) to identify somatic mutations and deep targeted sequencing of 134 genes selected from the initial screening in additional 48 germline and tumor pairs (62.5% HR-Event3 and high-risk patients), 17 HR-Event3 tumors and 17 human-derived neuroblastoma cell lines. We revealed 22 significantly mutated genes, many of which implicated in cancer progression. Fifteen genes (68.2%) were highly expressed in neuroblastoma supporting their involvement in the disease. CHD9, a cancer driver gene, was the most significantly altered (4.0% of cases) after ALK. Other genes (PTK2, NAV3, NAV1, FZD1 and ATRX), expressed in neuroblastoma and involved in cell invasion and migration were mutated at frequency ranged from 4% to 2%. Focal adhesion and regulation of actin cytoskeleton pathways, were frequently disrupted (14.1% of cases) thus suggesting potential novel therapeutic strategies to prevent disease progression. Notably BARD1, CHEK2 and AXIN2 were enriched in rare, potentially pathogenic, germline variants. In summary, whole exome and deep targeted sequencing identified novel cancer genes of clinically aggressive neuroblastoma. Our analyses show pathway-level implications of infrequently mutated genes in leading neuroblastoma progression. PMID:27009842

Sleep dlisorders of older adults seem to be caused by functional or organic changes in one or more of the three systems, and are roughly classified into two categories: (i) normal age-related, and (ii) pathological. The former includes decreased amplitude and advanced phase of circadian rhythms (body temperature, melatonin secretion, and sleep-waking), as well as reduced sleep duration, sleep fragmentation, and a decrease of slow-wave sleep in sleep architecture. Pathological sleep disorders include medical and psychiatric diseases (e.g., lifestyle-related diseases, dementia, delirium, and depression) and primary age-related sleep disorders (e.g., REM sleep behavior disorder and periodic limb move- ment disorders). This mini-review delineates the clinical features of sleep disorders in older adults.

    We describe a rare and apparently unique neuropathic syndrome among Navajo children living on the Navajo Reservation. Clinical features include sensorimotor neuropathy, corneal ulcerations, acral mutilation, poor weight gain, short stature, sexual infantilism, serious systemic infections, and liver derangement including Reye's syndrome-like episodes. Progressive CNS white matter lesions were diagnosed through magnetic resonance imaging. We identified 20 definite and 4 probable cases occurring between 1959 and 1986. Mean age at the time of 1st recognized symptom was 13 months (range, 1 month to 4 years 6 months). Ten individuals have died; 6 of the deaths occurred before 5 years of age. The incidence of this syndrome on the western Navajo reservation is 5 times higher than that on the eastern reservation (38 compared with 7 cases per 100,000 births). Although the etiology is unknown, this syndrome is consistent with an inborn error of metabolism, inherited in an autosomal recessive manner. PMID:2300261

    Acute esophageal mucosal lesions (AEMLs) are categorized into black esophagitis (type B) and non-black esophagitis (type NB) on endoscopy. To clarify the distinct pathophysiology, we compared the clinical features and hematological findings at onset among 17 patients with type B esophagitis and 6 patients with type NB esophagitis. In type B esophagitis, time to endoscopy after onset was significantly shorter, and blood levels of lactate, urea nitrogen, creatinine, and glucose were higher than in type NB esophagitis. However, there were no significant intergroup differences in the incidences of other predisposing factors, such as diabetic ketoacidosis or esophageal hernias. These findings suggest that AEMLs are caused by acid reflux and peripheral vascular insufficiency, the latter being more associated with type B esophagitis by its etiology. In addition, blood lactate may indicate the severity of AEML, leading to black esophagitis. PMID:27052393

    Neural tube defects (NTDs) constitute a major health burden (0.5-2/1000 pregnancies worldwide), and remain a preventable cause of still birth, neonatal, and infant death, or significant lifelong handicaps. The malformations result from failure of the neural folds to fuse in the midline, and form the neural tube between the third and the fourth week of embryonic development. This review article discusses their classification, clinical features, and genetics. Most NTDs are sporadic and both genetic, and non-genetic environmental factors are involved in its etiology. Consanguinity was suggested to contribute to the high incidence of NTDs in several countries, including Saudi Arabia. Syndromes, often associated with chromosomal anomalies, account for <10% of all NTDs; but a higher proportion (20%) has been documented in Saudi Arabia. Genetic predisposition constitutes the major underlying risk factor, with a strong implication of genes that regulate folate one-carbon metabolism and planar cell polarity. PMID:25551113

    Background Hand eczema is one of the most common skin disorders and negatively affects quality of life. However, a large-scale multicenter study investigating the clinical features of patients with hand eczema has not yet been conducted in Korea. Objective To identify the prevalence of various hand diseases, which is defined as all cutaneous disease occurring in hands, and to investigate the clinical features of patients with hand eczema and the awareness about hand eczema in the general population and to compare the prevalence of hand eczema between health care providers and non-health care providers. Methods To estimate the prevalence of hand diseases, we analyzed the medical records of patients from 24 medical centers. Patients were assessed by online and offline questionnaires. A 1,000 from general population and 913 hand eczema patients answered the questionnaire, for a total of 1,913 subjects. Results The most common hand disease was irritant contact dermatitis. In an online survey, the lifetime prevalence of hand eczema was 31.2%. Hand eczema was more likely to occur in females (66.0%) and younger (20~39 years, 53.9%). Health care providers and housewives were the occupations most frequently associated with hand eczema. Winter (33.6%) was the most common season which people experienced aggravation. The 63.0% and 67.0% answered that hand eczema hinders their personal relationship and negatively affects daily living activities, respectively. Conclusion Hand eczema is a very common disease and hinders the quality of life. The appropriate identification of hand eczema is necessary to implement effective and efficient treatment.

    Introduction Laryngeal tuberculosis (LTB) is the most frequent granulomatous disease of the larynx and represents less than 2% of extrapulmonary TB cases. There are no pathognomonic clinical and endoscopic features of this disease and studies on LTB that can assist in its diagnostic characterization are lacking. Objective To identify factors associated with clinical and topographical features of LTB. Method a retrospective cross-sectional study was conducted from the medical records of 36 patients with confirmed LTB diagnosis. Results Dysphonia and cough were the main symptoms presented by patients and the true vocal folds the most frequently affected site. The average of the duration of the disease evolution was significantly higher in patients with dysphonia than in patients without this symptom. We observed association between dysphonia and true vocal fold lesions and between odynophagia and lesions in the epiglottis, arytenoids and aryepiglottic folds. Odynophagia was more frequent in individuals with lesions in four or more laryngeal sites. Weight loss equal or above 10% of the body weight was more frequent in patients with odynophagia as first symptom and in patients with ulcerated lesion. Dyspnea on exertion was more frequent in individuals with more extensive laryngeal lesions. The percentage of smokers with lesions in four or more laryngeal sites was greater than that found in non-smokers. Laryngeal tissue fragment bacilloscopy and culture examinations were less positive than sputum ones. Conclusions Smoking appears to be associated with the development of more extensive LTB lesions, and LTB with dyspnea on exertion and odynophagia with consequent impairment of nutritional status. We emphasize the need for histopathologic confirmation, once positive sputum bacteriological examinations seem not to necessarily reflect laryngeal involvement. PMID:27077734

    Hairy cell leukemia (HCL) is a rare chronic lymphoproliferative disorder which has been extensively studied over the past decade. Much has been learned regarding the diagnosis, natural history, biology, and treatment of this unique neoplasm. The disease most commonly affects middle aged men and characteristic clinical features include splenomegaly, cytopenias, and usually the presence in the peripheral blood of distinctive 'hairy cells' with irregular cytoplasmic projections. Diagnosis can usually be confirmed by bone marrow biopsy. Although the natural history can be extremely variable among patients, complications are usually referable to the cytopenias, with anemia and infection being most frequent. In addition to pyogenic infections, patients are susceptible to unusual organisms including atypical mycobacterium, legionella, and fungi. The requirement of red blood cell transfusion, severe granulocytopenia or thrombocytopenia, frequent infections, or painful splenomegaly are all indications for treatment. Splenectomy is the standard initial treatment of choice. However, in the past few years there have been exciting major advances in the therapeutic modalities for HCL. Recombinant alpha-interferon is highly effective, with beneficial responses occurring in close to 90% of patients. The Food and Drug Administration has recently approved the use of interferon for HCL. This represents the first time a biological response modifier has been approved for the treatment of human disease. In addition, preliminary results with the adenosine deaminase inhibitor, 2'deoxycoformycin (dcf), have been encouraging. Further clinical trials are required in order to determine the optimal sequential treatment strategy for HCL. The exact mechanisms of action of both interferon and dcf in HCL remain to be elucidated. A better understanding of the unusual features of the hairy cell and the underlying biological effect of these two agents in HCL may have important applications in other

    Patients with co-morbid psychiatric disorders exhibiting violent and aggressive behaviors can be a challenge for nurses in medical-surgical units. They can deliver effective, safe care by assessing risk and building a rapport with the patient during the admission process; utilizing crisis prevention strategies, including appropriate medication administration, environmental, psychobiological, counseling, and health teaching interventions; and employing conflict resolution technique. Utilizing the nursing process, the nurse can provide effective therapeutic interventions to promote safety for both the patient and the nurse. PMID:18072668

    The authors discuss the diagnostic criteria for pedophilia and review the literature on its clinical features, including data on prevalence, gender, age of onset, number of victims, frequency and type of acts, violence, impulsivity, and insight. Findings concerning the characteristics of victims (e.g., sex, age, relationship to the pedophile) and research on pedophilic subtypes-exclusive versus nonexclusive; incestuous versus nonincestuous; heterosexual, homosexual, or bisexual-are reviewed. Studies have shown that pedophiles may share many psychiatric features beyond deviant sexual desire, including high rates of comorbid axis I disorders (affective disorders, substance use disorders, impulse control disorders, other paraphilias) as well as severe axis II psychopathology (especially antisocial and Cluster C personality disorders). The authors present several possible etiological models for pedophilia and conclude that further research is needed concerning the etiological role of a childhood history of sexual abuse as well as the underlying neurobiology of deviant sexual arousal and decreased erotic differentiation. Finally, findings concerning pharmacological and cognitive-behavioral treatments for pedophilia are briefly reviewed. Recidivism, drop-out, and noncompliance are significant problems in the treatment of pedophilia. The authors review predictors of treatment outcome and conclude that pedophilia is extremely difficult to treat and that effective treatment needs to be intensive, long-term, and comprehensive, possibly with lifetime follow-up.

    Pancreatic neuroendocrine tumors (pNETs) comprise with gastrointestinal carcinoids, the main groups of gastrointestinal neuroendocrine tumors (GI-NETs). Although these two groups of GI-NETs share many features including histological aspects; over-/ectopic expression of somatostatin receptors; the ability to ectopically secrete hormones/peptides/amines which can result in distinct functional syndromes; similar approaches used for tumor localization and some aspects of treatment, it is now generally agreed they should be considered separate. They differ in their pathogenesis, hormonal syndromes produced, many aspects of biological behavior and most important, in their response to certain anti-tumor treatment (chemotherapy, molecular targeted therapies). In this chapter the clinical features of the different types of pNETs will be considered as well as aspects of their diagnosis and medical treatment of the hormone-excess state. Emphasis will be on controversial areas or recent advances. The other aspects of the management of these tumors (surgery, treatment of advanced disease, tumor localization) are not dealt with here, because they are covered in other chapters in this volume.

    Spinocerebellar ataxia type 3 (SCA3) is a rare inherited autosomal dominant progressive neurological disorder, which results from a CAG‑repeat expansion in the gene encoding the deubiquitinating enzyme, ataxin‑3. At present, no effective treatment is available for this fatal disorder; however, certain studies have suggested that reducing the levels of mutant ataxin‑3 protein may reverse or halt the progression of disease in patients with SCA3. In the present study, clinical examinations were performed on a patient with SCA3 who exhibited disease features including coughing, expectoration and was bedridden with mobility limitation. CAG repetitions at SCA‑associated genes were detected in the patient's family by performing standard polymerase chain reaction (PCR) and triple‑repeat primed PCR. The numbers of CAG‑repeats within the two alleles of the gene of interest in the patient were 15 and 78. Notably, the patient's brother, who harbored 76 CAG‑repeats in one allele of the gene of interest, did not exhibit severe disease symptoms. These results suggest that the number of CAG‑repeats is a critical for determination of SCA3 disease severity and time of onset. In addition, the defined phenotypic characteristics of the patient in the present study provide useful insight for more accurate clinical diagnosis and genotyping of future patients. PMID:27600091

    A dopaminergic deficiency in patients with Parkinson's disease (PD) causes abnormalities of movement, behaviour, learning, and emotions. The main motor features (ie, tremor, rigidity, and akinesia) are associated with a deficiency of dopamine in the posterior putamen and the motor circuit. Hypokinesia and bradykinesia might have a dual anatomo-functional basis: hypokinesia mediated by brainstem mechanisms and bradykinesia by cortical mechanisms. The classic pathophysiological model for PD (ie, hyperactivity in the globus pallidus pars interna and substantia nigra pars reticulata) does not explain rigidity and tremor, which might be caused by changes in primary motor cortex activity. Executive functions (ie, planning and problem solving) are also impaired in early PD, but are usually not clinically noticed. These impairments are associated with dopamine deficiency in the caudate nucleus and with dysfunction of the associative and other non-motor circuits. Apathy, anxiety, and depression are the main psychiatric manifestations in untreated PD, which might be caused by ventral striatum dopaminergic deficit and depletion of serotonin and norepinephrine. In this Review we discuss the motor, cognitive, and psychiatric manifestations associated with the dopaminergic deficiency in the early phase of the parkinsonian state and the different circuits implicated, and we propose distinct mechanisms to explain the wide clinical range of PD symptoms at the time of diagnosis.

    Flavimonas oryzihabitans is rarely reported as a pathogen in humans. Twelve cases of F. oryzihabitans bacteremia were diagnosed at National Taiwan University Hospital over a 3-year period. The clinical features of these patients were analyzed, and antimicrobial susceptibilities and random amplified polymorphic DNA (RAPD) patterns of the 12 isolates were studied. Among these 12 patients, eight (67%) had underlying neoplastic diseases and all acquired F. oryzihabitans bacteremia while hospitalized. The clinical syndromes included primary bacteremia in 5 patients (42%), biliary tract infection in 3 (25%), and peritonitis, subdural empyema, infusion-related bacteremia, and pneumonia in 1 each. Polymicrobial bacteremia or concomitant fungemia was seen in three patients (25%). All the patients survived after antibiotic treatment. All isolates were susceptible to piperacillin, third-generation cephalosporins, aminoglycosides, and quinolones but resistant to cephalothin, cefuroxime, and trimethoprim. Susceptibility to aztreonam was variable (25%). The RAPD patterns differed among the isolates, indicating the epidemiological unrelatedness of these infections. F. oryzihabitans should be included as an etiology of severe nosocomial infection in patients with underlying debilitating diseases.

    Ebola virus disease is caused by a highly contagious and pathogenic threadlike RNA virus of the Filoviridae family. The index human case is usually a zoonosis that launches human-to-human transmission interface with varying levels of sustainability of the epidemic depending on the level of public health preparedness of the affected country and the Ebola virus strain. The disease affects all age groups in the population. Clinical diagnosis is challenging in index cases especially in the early stages of the disease when the presenting features are usually nonspecific and only similar to a flu-like illness. However, in the agonal stages, hemorrhage frequently occurs in a high proportion of cases. The diagnostic gold standard is by detecting the antigen using reverse transcription-polymerase chain reaction. Mortality rates in the past 28 outbreaks since 1976 have ranged from 30% to 100% in different settings among adults, but lower mortality rates have been documented in children. This review aims to describe Ebola virus infection, clinical presentation, diagnosis and outcomes in children.

    Data regarding validity of clinical and radiographic findings in diagnosing patellofemoral pain syndrome are inconclusive. We prospectively assessed how sensitive and specific key patellofemoral physical examination tests are, and evaluated the prevalence of physical examination and radiographic findings. Sixty-one infantry soldiers with patellofemoral pain syndrome and 25 control subjects were evaluated. The sensitivity of the patellar tilt, active instability, patella alta, and apprehension tests was low (less than 50%); specificity ranged between 72% and 100%. Although the prevalence of positive patellar tilt and active instability tests was significantly greater in subjects with patellofemoral pain syndrome, there were no significant differences between the groups in the results of the other two tests. Soldiers with patellofemoral pain syndrome presented with increased quadriceps angle, lateral and medial retinacular tenderness, patellofemoral crepitation, squinting patella, and reduced mobility of the patella. There were no differences between the groups in the prevalence of lower limb and foot posture alignment and knee effusion. Plain radiography showed increased patellar subluxation in soldiers with patellofemoral pain syndrome. Other radiographic measures (sulcus angle, Laurin angle, Merchant angle, and Insall-Salvati index) were similar in both groups. We provide evidence regarding the validity of clinical and radiographic features commonly used for diagnosing patellofemoral pain syndrome. Physical examinations were more useful than plain radiography. PMID:16788411

    The aim of this study was to investigate the clinical features and treatment results of endophthalmitis after cataract surgery. Five patients with endophthalmitis after phacoemulsification with intraocular lens implantation were enrolled in this study. The pathogenesis, clinical manifestation, and surgical outcomes of 5 patients were compared. Three patients were surgically treated with anterior chamber irrigation and vitrectomy with intravitreal injection. The remaining two patients were medically treated with an intravitreal injection of vancomycin and ceftazidime. Treatment results of the five patients were analyzed. Four patients had positive cultures for bacteria (two cases Staphylococcus epidermidis, one case Enterococcus faecalis, and one case head-like Staphylococcus). The culture of the fifth patient did not have bacterial growth. One year following treatment, four patients had restored visual acuity and a clear vitreous cavity. Retinal detachment and other complications were not observed. The remaining patient had a visual acuity of index at 30 cm one year following treatment. For patients with endophthalmitis after cataract surgery, a biochemical laboratory examination should be promptly performed and should include a bacterial culture and drug sensitivity test. When necessary, vitrectomy combined with an intravitreal injection of vancomycin should be performed to treat the infection early and to help retain useful vision. PMID:26125869

    To investigate the clinical features, risk factors, and bacterial spectrum of liver abscess following transarterial chemoembolization (TACE) and evaluate the therapeutic effect of percutaneous catheter drainage (PCD) on the abscesses.A retrospective review of patient charts was performed in 3613 patients who suffered from liver malignancies (2832 patients with hepatocellular carcinoma and 781 with metastatic hepatic tumor) and had undergone 11,054 TACE procedures from January 2005 to October 2013. Liver abscesses were found in 21 patients. PCD was performed in all abscess patients. The clinical features, risk factors, and bacterial spectrum of liver abscess following TACE were investigated and the therapeutic effect of PCD was evaluated.The incidence of liver abscess was 0.58% per patient and 0.19% per procedure. Approximately 57.1% of the patients had a medical history of bilioenteric anastomosis or biliary stent implantation. On computed tomography scans, the abscesses appeared as low-attenuation lesions and high-density iodinate oil scattered in the abscesses. The ultrasound showed the well defined, heterogeneously hypoechoic lesions. Positive microbiological isolates were obtained in all pus cultures and in 47.6% of blood cultures. The most common bacterium was Escherichia coli (52.4%). Twenty patients (95.2%) were cured from abscesses by using PCD, and 1 died of sepsis.Patients with predisposing factors are prone to an increased risk of liver abscess following TACE. Bacterial culture and antibiotic sensitivity tests on pus and blood help on the antibiotics selection. PCD combined with aggressive antibiotics can be recommended as the first-line therapeutic regimen. PMID:27124055

    Objective To study serious harms associated with selective serotonin and serotonin-norepinephrine reuptake inhibitors. Design Systematic review and meta-analysis. Main outcome measures Mortality and suicidality. Secondary outcomes were aggressive behaviour and akathisia. Data sources Clinical study reports for duloxetine, fluoxetine, paroxetine, sertraline, and venlafaxine obtained from the European and UK drug regulators, and summary trial reports for duloxetine and fluoxetine from Eli Lilly’s website. Eligibility criteria for study selection Double blind placebo controlled trials that contained any patient narratives or individual patient listings of harms. Data extraction and analysis Two researchers extracted data independently; the outcomes were meta-analysed by Peto’s exact method (fixed effect model). Results We included 70 trials (64 381 pages of clinical study reports) with 18 526 patients. These trials had limitations in the study design and discrepancies in reporting, which may have led to serious under-reporting of harms. For example, some outcomes appeared only in individual patient listings in appendices, which we had for only 32 trials, and we did not have case report forms for any of the trials. Differences in mortality (all deaths were in adults, odds ratio 1.28, 95% confidence interval 0.40 to 4.06), suicidality (1.21, 0.84 to 1.74), and akathisia (2.04, 0.93 to 4.48) were not significant, whereas patients taking antidepressants displayed more aggressive behaviour (1.93, 1.26 to 2.95). For adults, the odds ratios were 0.81 (0.51 to 1.28) for suicidality, 1.09 (0.55 to 2.14) for aggression, and 2.00 (0.79 to 5.04) for akathisia. The corresponding values for children and adolescents were 2.39 (1.31 to 4.33), 2.79 (1.62 to 4.81), and 2.15 (0.48 to 9.65). In the summary trial reports on Eli Lilly’s website, almost all deaths were noted, but all suicidal ideation events were missing, and the information on the remaining outcomes was

    Purpose Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and heterogeneous tumors, and their biological behavior is not well known. We studied the presence and potential functional roles of somatostatin receptors (sst1-5), focusing particularly on the truncated variants (sst5TMD4, sst5TMD5) and on their relationships with the angiogenic system (Ang/Tie-2 and VEGF) in human GEP-NETs. Experimental Design We evaluated 42 tumor tissue samples (26 primary/16 metastatic) from 26 patients with GEP-NETs, and 30 non-tumoral tissues (26 from adjacent non-tumor regions and 4 from normal controls) from a single center. Expression of sst1-5, sst5TMD4, sst5TMD5, Ang1-2, Tie-2 and VEGF was analyzed using real-time qPCR, immunofluorescence and immunohistochemistry. Expression levels were associated with tumor characteristics and clinical outcomes. Functional role of sst5TMD4 was analyzed in GEP-NET cell lines. Results sst1 exhibited the highest expression in GEP-NET, whilst sst2 was the most frequently observed sst-subtype (90.2%). Expression levels of sst1, sst2, sst3, sst5TMD4, and sst5TMD5 were significantly higher in tumor tissues compared to their adjacent non-tumoral tissue. Lymph-node metastases expressed higher levels of sst5TMD4 than in its corresponding primary tumor tissue. sst5TMD4 was also significantly higher in intestinal tumor tissues from patients with residual disease of intestinal origin compared to those with non-residual disease. Functional assays demonstrated that the presence of sst5TMD4 was associated to enhanced malignant features in GEP-NET cells. Angiogenic markers correlated positively with sst5TMD4, which was confirmed by immunohistochemical/fluorescence studies. Conclusions sst5TMD4 is overexpressed in GEP-NETs and is associated to enhanced aggressiveness, suggesting its potential value as biomarker and target in GEP-NETs. PMID:26673010

    Amebic liver abscess (ALA) is a serious, but readily treatable form of hepatic infection. In order to understand the clinical features of this condition in the United States, we reviewed the medical histories of 56 patients with ALA at two large San Francisco Hospitals from 1979 to 1994. Patients were divided into the following groups based on the presumed manner in which they had acquired ALA: those born or raised in the United States, with a history of travel to an endemic area (Tr-ALA); those from an endemic area, but living in the United States for less than one year (En-ALA); and those neither from nor having traveled to an endemic area (N-ALA). We found distinct clinical patterns in patients from different epidemiological groups. Patients with Tr-ALA were a decade older than those from endemic regions, were more likely to be male, and tended to have an insidious onset. Furthermore, compared to patients with En-ALA, those with Tr-ALA were more likely to have hepatomegaly (P < 0.0001) and large abscesses (ALA > 10 cm; P < 0.01). One third of the patients studied had no associated travel history or endemic origin as risk factors. Of these, 63% had a condition consistent with severe immunosuppression, such as infection with the human immunodeficiency virus (HIV), malnourishment with severe hypoalbuminemia, or chronic infection. In patients with N-ALA, the presence of a presumed immunosuppressed state increased significantly, as compared to patients with endemic or travel risk factors for ALA. During the last five years of the study, one third of all patients diagnosed with ALA were HIV positive (including 2 with a new diagnosis of AIDS), many of whom were discovered to be HIV-infected only after presentation with ALA. We conclude that travel to and origin in an endemic area are important risk factors for the development of ALA, and patients in these different epidemiological groups appear to have distinct clinical features. Further, in the absence of recognized

    Abstract Extraintestinal manifestations (EIMs) cause increased morbidity and decreased quality of life in Crohn disease (CD). Ankylosing spondylitis (AS) belongs to EIMs. Very little is known on the clinical features of CD concomitant with AS. This study is to investigate the clinical features of CD patients with AS. We retrospectively collected all CD patients with AS in our hospital, and established a comparison group (CD without AS) with age, sex, and duration of Crohn disease matched. Clinical information was retrieved for comparison. Eight CD + AS patients were identified from 195 CD patients. Sixteen CD patients were randomly selected into comparison group. All CD + AS patients were male, HLA-B27 (+), and rheumatoid factor (−) with an average age of 40.8 ± 4.52 years. Significant correlation between disease activity of CD and AS was revealed (r = 0.857, P = 0.011). Significant correlation between disease activity of CD and functional limitation associated with AS was identified (r = 0.881, P < 0.01). C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and globulin were positively correlated to Crohn disease activity index (CDAI), Bath AS disease activity index, and Bath AS functional index(BASFI) scores (r = 0.73–0.93, P < 0.05). Albumin was negatively associated with CDAI and BASFI (r = −0.73 to −0.91, P < 0.05). The ratio of albumin to globulin (Alb/Glo) was significantly related to all 3 scores (r = −0.81 to −0.91, P < 0.05). Male predominance with a 4.12% concomitant incidence of AS is observed in CD patients. Disease activity of CD correlates with disease activity of AS and functional limitation caused by AS. CRP, ESR, and Alb/Glo may serve as biomarkers for disease activity and functional limitation in CD patients concomitant with AS, although future studies are expected. PMID:27428240

    In the last years, several studies of molecular profiling of aggressive lymphomas were performed. In particular, it was shown that DLBCL can be distinguished in two different entities according to GEP. Specifically, ABC and GCB subtypes were characterized by having different pathogenetic and clinical features. In addition, it was demonstrated that DLBCLs are distinct from BL. Indeed, the latter is a unique molecular entity. However, relevant pathological differences emerged among the clinical subtypes. More recently, microRNA profiling provided further information concerning BL-DLBCL distinction as well as for their subclassification. In this paper, the authors based on their own experience and the most updated literature review, the main concept on molecular profiling of aggressive lymphomas. PMID:22190944

    Multifocal hepatic hemangioma (MHH) is a benign hepatic tumor that is commonly diagnosed in children with multiple cutaneous infantile hemangiomas (IHs). We present a review of all children with MHH at our institutions. Of the 42 patients, the median age at presentation of MHH was 2.5 months. Thirty-six (85.7%) patients had cutaneous IHs. Twelve (28.6%) patients were symptomatic at presentation. There was no significant association between the number of hepatic hemangiomas and the number of cutaneous IHs. Fourteen (33.3%) patients received some form of treatment for hepatic hemangiomas. The most common type of treatment was oral prednisone in 8 patients, followed by oral propranolol in 6 patients. Two patients were totally resistant to prednisone treatment. They died from congestive heart failure or respiratory distress and coagulopathy. Two patients with problematic facial IH were treated with intralesional triamcinolone injection. The remaining 26 patients were managed with imaging surveillance. On follow-up, all of the survivors had a favorable outcome. Our study suggests that the clinical features of MHH are variable. Our data emphasize the treatment strategy that aggressive treatment is indicated in symptomatic or progressive MHHs, whereas observation management of asymptomatic patients with a few small lesions is safe and appropriate.

    Abstract Pasteurella multocida, a zoonotic infectious organism, has most often been described in patients after an animal bite. Here, we characterize the clinical features and outcomes of P multocida infection in a large cohort of patients according to the presence or absence of an animal bite. We retrospectively searched MUSC's laboratory information system for all patients with positive P multocida cultures from 2000 to 2014. Extensive data were abstracted, including clinical and outcome data. The Charlson comorbidity index (CCI) was used to assess comorbidities among patients. We identified 44 patients with P multocida infections, including 25 with an animal bite. The average age was 64 years and the majority of patients were women (N = 30). There was no difference in age and sex distribution among those with and without a bite (P = 0.38 and 0.75, respectively). A CCI ≥1 was significantly associated with the absence of a bite (P = 0.006). Patients presenting without a bite were more frequently bacteremic (37% vs 4%, respectively, P = 0.001), and were hospitalized more often (84% vs 44%, respectively, P = 0.012). Of the 8 patients who required intensive care unit (ICU)-based care, 7 were non-bite-related. There were 4 deaths, all occurring in patients not bitten. P multocida infections not associated with an animal bite were often associated with bacteremia, severe comorbidity(ies), immune-incompetent states, the need for ICU management, and were associated with substantial mortality.

    BACKGROUND: Dilatation of the rectum and/or colon, in the absence of demonstrable organic disease, is an uncommon and poorly characterised condition. AIMS: To characterise the clinical and diagnostic features, and response to treatment, of patients with idiopathic megarectum (IMR) and idiopathic megacolon (IMC). METHODS: A retrospective review was undertaken of all patients operated on for these conditions over a 23 year period. In addition all patients treated over a three year period were prospectively studied by means of a questionnaire, contrast studies of the upper and lower intestine, spine x rays to exclude spinal dysraphism, anorectal physiological studies, and assessment of clinical outcome. Patients with Hirschsprung's disease and other known causes of gut dilatation were excluded. RESULTS: (i) Retrospective study: Of 63 operated patients, 22 had IMR, 23 had IMR and IMC, and 18 had IMC only. Five patients with IMC had previous sigmoid volvulus, and three had associated non-gastrointestinal congenital abnormalities. Faecal incontinence was always associated with rectal impaction and 14 patients (82%) with IMR alone had had manual disimpaction. (ii) Prospective study: Twenty two patients had IMR, with a median rectal diameter of 10 cm (normal < 6.5 cm). Six patients had IMC and one patient had IMR and IMC. Patients with IMR were significantly (p = 0.0007) younger than patients with IMC. All patients with IMR became symptomatic in childhood, compared with half the patients with IMC who developed symptoms as adults. Patients with IMR all presented with soiling and impaction, compared with patients with IMC whose symptoms were variable and included constipation or increased bowel frequency, pain, and variable need for laxatives. No upper gut dilatation was seen in either group of patients. Spinal dysraphism was seen in two of 18 patients with IMR and two of four with IMC, suggesting extrinsic denervation as a possible cause in a minority. Twelve of 22 patients

    Background Morgellons is a poorly characterized constellation of symptoms, with the primary manifestations involving the skin. We conducted an investigation of this unexplained dermopathy to characterize the clinical and epidemiologic features and explore potential etiologies. Methods A descriptive study was conducted among persons at least 13 years of age and enrolled in Kaiser Permanente Northern California (KPNC) during 2006–2008. A case was defined as the self-reported emergence of fibers or materials from the skin accompanied by skin lesions and/or disturbing skin sensations. We collected detailed epidemiologic data, performed clinical evaluations and geospatial analyses and analyzed materials collected from participants' skin. Results We identified 115 case-patients. The prevalence was 3.65 (95% CI = 2.98, 4.40) cases per 100,000 enrollees. There was no clustering of cases within the 13-county KPNC catchment area (p = .113). Case-patients had a median age of 52 years (range: 17–93) and were primarily female (77%) and Caucasian (77%). Multi-system complaints were common; 70% reported chronic fatigue and 54% rated their overall health as fair or poor with mean Physical Component Scores and Mental Component Scores of 36.63 (SD = 12.9) and 35.45 (SD = 12.89), respectively. Cognitive deficits were detected in 59% of case-patients and 63% had evidence of clinically significant somatic complaints; 50% had drugs detected in hair samples and 78% reported exposure to solvents. Solar elastosis was the most common histopathologic abnormality (51% of biopsies); skin lesions were most consistent with arthropod bites or chronic excoriations. No parasites or mycobacteria were detected. Most materials collected from participants' skin were composed of cellulose, likely of cotton origin. Conclusions This unexplained dermopathy was rare among this population of Northern California residents, but associated with significantly reduced health-related quality of

    Mucocele is a benign lesion occurring in the buccal mucosa as a result of the rupture of a salivary gland duct and consequent outpouring of mucin into soft tissue. It is usually caused by a local trauma, although in many cases the etiology is uncertain. Mucocele is more commonly found in children and young adults, and the most frequent site is the lower inner portion of the lips. Fibroma, on the other hand, is a benign tumor of fibrous connective tissue that can be considered a reactionary connective tissue hyperplasia in response to trauma and irritation. They usually present hard consistency, are nodular and asymptomatic, with a similar color to the mucosa, sessile base, smooth surface, located in the buccal mucosa along the line of occlusion, tongue and lip mucosa. Conventional treatment for both lesions is conservative surgical excision. Recurrence rate is low for fibroma and high for oral mucoceles. This report presents a series of cases of mucocele and fibroma treated by surgical excision or enucleation and the respective follow-up routine in the dental clinic and discusses the features to be considered in order to distinguish these lesions from each other.

  8. Clinical features of Eosinophilic esophagitis in children and adults.

    Eosinophilic esophagitis (EoE) may affect humans at any age with a predominance for Caucasian males. The clinical manifestation of EoE varies depending on the patient's age. Infants and young children may primarily present with unspecific symptoms such as feeding problems, vomiting and abdominal pain. In adolescents and adults, dysphagia and food impactation become the predominant symptoms. EoE should also be considered in cases of refractory heartburn in both children and adults. Concomitant allergic diseases such as asthma, rhinitis and eczema, as well as peripheral eosinophilia and elevated total serum IgE values are common in pediatric and adult EoE patients. EoE seems to be primarily a food antigen-driven disease, whereas in adults, aeroallergen sensitization may dominate. Endoscopic features of EoE include mucosal edema, furrows, exudates, corrugated rings, strictures, and the so-called crepe paper sign. There appears to be a shift from an inflammatory-predominant phenotype in young childhood towards a more fibrotic phenotype in adolescents and adults. Long-term follow studies suggest that EoE is a chronic and potentially progressive disease causing recurring dysphagia in the majority of cases. The prevalence of strictures significantly increases with the duration of untreated disease, stressing the importance of early diagnosis and consequent treatment of EoE. PMID:26552773

    Context It has been reported that childhood psychotic symptoms are common in the general population and may signal neurodevelopmental processes that lead to schizophrenia. However, it is not clear whether these symptoms are associated with the same extensive risk factors established for adult schizophrenia. Objective To examine the construct validity of children’s self-reported psychotic symptoms by testing whether these symptoms share the risk factors and clinical features of adult schizophrenia. Design Prospective, longitudinal cohort study of a nationally representative birth cohort in Great Britain. Participants A total of 2232 twelve-year-old children followed up since age 5 years (retention, 96%). Main Outcome Measure Children’s self-reported hallucinations and delusions. Results Children’s psychotic symptoms are familial and heritable and are associated with social risk factors (eg, urbanicity); cognitive impairments at age 5; home-rearing risk factors (eg, maternal expressed emotion); behavioral, emotional, and educational problems at age 5; and comorbid conditions, including self-harm. Conclusions The results provide a comprehensive picture of the construct validity of children’s self-reported psychotic symptoms. For researchers, the findings indicate that children who have psychotic symptoms can be recruited for neuroscience research to determine the pathogenesis of schizophrenia. For clinicians, the findings indicate that psychotic symptoms in childhood are often a marker of an impaired developmental process and should be actively assessed. PMID:20368509

    Our purpose was to describe the clinical features of patients with novel Yersinia species. Between 1985 and 1999; 194 patients had yersinia species isolated from stool specimens, 38 (20%) had non-Yersinia enterocolitica species; 12 (32%) had Yersinia intermedia, 7 (18%) Yersinia fredericksenii, 3 (8%) Yersinia kristensenii, and the remaining 16 (42%) were unclassified non-Yersinia enterocolitica species. The most common presenting symptom was diarrhea alone in 10 (26.3%) patients. Symptoms persisted for >1 month in 54% of cases; 21% had symptoms for <1 week; 18 (47%) patients were taking corticosteroids, acid suppressants, and/or antibiotics when Yersinia was isolated. An immunocompromised state was present in 11 (29%) patients. An immunocompromised host and administration of acid suppressants predicted persistence of symptoms for >1 month. Most [27 (71%)] patients received no treatment; 5 (13%) received antibiotics. In conclusion, novel non-Yersinia enterocolitica species, including Yersinia intermedia, Y. fredericksenii, and Y. kristensenii may represent up to 20% of all Yersinia isolates. Diarrhea is the most common symptom.

    The aim of the present study was to comprehensively evaluate the clinical features and long-term outcomes of congenital aural stenosis (CAS). This study presents a retrospective review of patients who underwent meatoplasty for CAS at a tertiary referral hospital from 2008 to 2015. A total of 246 meatoplasty procedures were performed on 232 patients in the present study. We performed multivariate regression analysis. Except in the age < 6 years group, no significant difference was observed among different age groups for cholesteatoma formation, p > 0.05. Except for the stenosis of the external auditory canal (EAC) (>4 mm) group, the other stenosis of EAC groups were not associated with cholesteatoma formation, p > 0.05. Postoperative air-bone gaps (ABG) less than 30 dB occurred in 77.3% (99/128) of the patients, and the Jahrsdoerfer score was associated with postoperative ABG, p < 0.001. The complication rate of CAS was 13.8% (20/144), and males showed a higher risk for postoperative complications (OR, 6.563; 95% CI, 1.268–33.966, p = 0.025). These results indicate that meatoplasty was an effective surgical intervention for CAS, showing a stable hearing outcome with prolonged follow-up. There was no significant difference between the cholesteatoma and no cholesteatoma groups for hearing outcomes, p > 0.05. PMID:27257165

    The purpose of this study is to clarify the clinical features of the knee affected by multiple epiphyseal dysplasia. Thirty-one cases of multiple epiphyseal dysplasia were reviewed. Of the patients, 11 were male and 20 were female. The average age at onset of symptoms was 22.5 years. The average age at initial visit to the authors' hospital was 28.9 years. Radiographic findings showed epiphyseal abnormality of the knee in all but two (93%) cases. Irregularity, segmentation of the epiphysis, widening of the joint space, and genu valgum deformity were the dominant findings before epiphyseal closure. After epiphyseal closure, the most characteristic finding was a shallow femoral trochlear groove, which was observed in 56.5% of the cases. Other findings in adult patients included early onset osteoarthritic change, genu valgum, depression of the lateral tibial plateau, and multiple free bodies. However, there still is a possibility that multiple epiphyseal dysplasia exists, even if the patient lacks a shallow femoral trochlear groove. If genu valgum or varum, free bodies, and premature osteoarthritis are observed, one should evaluate other joints, keeping a diagnosis of multiple epiphyseal dysplasia in mind. Patients with knees that have a femoral trochlear groove of normal or near normal shape do exist, and premature osteoarthritic changes may develop in such patients. PMID:11064990

    In this retrospective study, we report the clinical and biochemical features of diabetic ketoacidosis (DKA) in adult patients who were managed at the Instituto Nacional de la Nutrición during a 6.5 year period. There were 98 episodes in 46 patients: 22 females (48%) and 24 males (52%). Six patients (13%) had four or more episodes of DKA. Thirty five percent of the events occurred in patients with IDDM; 48% in "late onset" NIDDM: 9% in "early onset" and 9% in classical NIDDM. Infections as the precipitating factor in 41% of episodes of DKA were the initial manifestation of diabetes. We compared our results with those from other reported series, finding no differences among them. The mean anion gap in our series was 30.4. Main complications identified were hypokalemia in five cases, hypoglycemia in four cases, hypernatremia in four cases, and acute pulmonary edema, ventricular fibrillation, neurological deficit and coma in one case each. There were three deaths (6.5%) in the whole group. To our knowledge, this is the largest series on adult patients with DKA reported in our country in the last decade. The obtained results may help evaluate prospectively the impact of different diagnostic and therapeutic strategies in the management of DKA.

    Hepatitis delta virus, discovered in 1977, requires the help of hepatitis B virus to replicate in hepatocytes and is an important cause of acute, fulminant, and chronic liver disease in many regions of the world. Because of the helper function of hepatitis delta virus, infection with it occurs either as a coinfection with hepatitis B or as a superinfection of a carrier of hepatitis B surface antigen. Although the mechanisms of transmission are similar to those of hepatitis B virus, the patterns of transmission of delta virus vary widely around the world. In regions of the world in which hepatitis delta virus infection is not endemic, the disease is confined to groups at high risk of acquiring hepatitis B infection and high-risk hepatitis B carriers. Because of the propensity of this viral infection to cause fulminant as well as chronic liver disease, continued incursion of hepatitis delta virus into areas of the world where persistent hepatitis B infection is endemic will have serious implications. Prevention depends on the widespread use of hepatitis B vaccine. This review focuses on the molecular biology and the clinical and epidemiologic features of this important viral infection.

    Leptospirosis is a severe zoonotic disease that constitutes a major public health problem for the island populations of French Polynesia. Due to protean clinical manifestations and the risk of misdiagnosis with dengue fever, endemic viral disease, laboratory studies are necessary to confirm diagnosis of leptospirosis. At the request of the Pacific Public Health Surveillance Network, a prospective study was conducted in the population of Raieatea in the Windward Islands and the Marquis Islands to determine the epidemiological features of the disease and to define appropriate control measures. A total of 113 patients were enrolled in study between March 2004 and March 2005. Thirty-three cases were confirmed based on demonstration of serum DNA or seroconversion. The estimated annual incidence of leptospirosis was 1.7 per 1000 inhabitants. Cases involved mainly (75%) young men (mean age, 30.5 years) and occurred predominantly during the rainy season. Swimming in fresh water was the only factor showing significant correlation (p < 0.02) with positive diagnosis of leptospirosis. The most frequently identified serotype was Leptospira icterohemorrahgiae (43% of strains), thus suggesting that the rat was the most common human transmission vector. However other serotypes were found, underlining the presence of diverse reservoirs and casting doubt on the efficacy of immunization using a monovalent vaccine. These findings also indicate that enhancement of prevention and control measures for leptospirosis is needed.

    The clinical and serologic features of 36 patients with polymyositis (PM) or dermatomyositis (DM) were observed over a 5-year period. The mean age of the patients at the time of diagnosis was 48.5 years, and 61% were female. According to widely accepted diagnostic criteria 50% had PM (group I), 14% DM (group II), 11% PM or DM associated with malignant disease (group III) and 25% PM or DM associated with a connective tissue disorder (group V). None of the patients had childhood PM or DM associated with vasculitis (group IV). All the patients had muscle weakness, and 94% of the patients tested had an elevated serum level of creatine kinase. The average delay from the onset of symptoms to diagnosis was 14 months overall but only 2.3 months for the DM patients. Of the 30 patients whose serum was tested, 73% had antinuclear antibodies, with antibodies to nuclear ribonucleoprotein being most common in group V patients and antibodies directed against the Jo-1 antigen being restricted to patients with PM alone (group I).

    Serum sickness is a delayed immune reaction in which the immune system responds to a protein in antiserum as a potentially harmful substance and mounts an IgG-mediated antibody response. A 32 year-old female patient had systemic envenoming following a bite by a red-bellied black snake (Pseudechis porphyriacus). She was treated with Tiger snake antivenom and recovered over 24 h and did not develop myotoxicity. She then presented with local pain, itching and swelling, which was partially treated with antihistamines. Eleven days after the bite she presented again with symptoms of worsening serum sickness including rash on the upper legs, joint and muscle pain in arms, ankles and knees, and nausea. The patient was prescribed five days of prednisone 50 mg/day, antihistamine 10 mg/day and analgesia 1000 mg/day and improved over 2 days. She had no further problems on follow up at 4 months. This case highlights that serum sickness can cause significant effects after the treatment of snake envenoming. It develops 5-14 days after antivenom administration and has characteristic clinical and laboratory features. Severe cases of serum sickness can result in morbidity but it appears to respond well to corticosteroid treatment. PMID:26525657

    BACKGROUND Molecular markers that can discriminate indolent cancers from aggressive ones may improve the management of prostate cancer and minimize unnecessary treatment. Aberrant DNA methylation is a common epigenetic event in cancers and HOXD3 promoter hypermethylation (H3PH) has been found in prostate cancer. Our objective was to evaluate the relationship between H3PH and clinicopathologic features in screening prostate biopsies. METHODS Ninety-two patients who underwent a prostate biopsy at our institution between October 2011 and May 2012 were included in this study. The core with the greatest percentage of the highest grade disease was analyzed for H3PH by methylation-specific PCR. Correlational analysis was used to analyze the relationship between H3PH and various clinical parameters. Chi-square analysis was used to compare H3PH status between benign and malignant disease. RESULTS Of the 80 biopsies with HOXD3 methylation status assessable, 66 sets were confirmed to have cancer. In the 14 biopsies with benign disease there was minimal H3PH with the mean percentage of methylation reference (PMR) of 0.7%. In contrast, the HOXD3 promoter was hypermethylated in 16.7% of all cancers and in 50% of high risk tumors with an average PMR of 4.3% (P = 0.008). H3PH was significantly correlated with age (P = 0.013), Gleason score (P = 0.031) and the maximum involvement of the biopsy core (P = 0.035). CONCLUSIONS H3PH is associated with clinicopathologic features. The data indicate that H3PH is more common in older higher risk patients. More research is needed to determine the role of this marker in optimizing management strategies in men with newly diagnosed prostate cancer. Prostate 74:714–721, 2014. © 2014 The Authors.

    X-linked acro-gigantism (X-LAG) syndrome is a newly described disease caused by microduplications on chromosome Xq26.3 leading to copy number gain of GPR101. We describe the clinical progress of a sporadic male X-LAG syndrome patient with an Xq26.3 microduplication, highlighting the aggressive natural history of pituitary tumor growth in the absence of treatment. The patient first presented elsewhere aged 5 years 8 months with a history of excessive growth for >2 years. His height was 163 cm, his weight was 36 kg, and he had markedly elevated GH and IGF-1. MRI showed a non-invasive sellar mass measuring 32.5 × 23.9 × 29.1 mm. Treatment was declined and the family was lost to follow-up. At the age of 10 years and 7 months, he presented again with headaches, seizures, and visual disturbance. His height had increased to 197 cm. MRI showed an invasive mass measuring 56.2 × 58.1 × 45.0 mm, with compression of optic chiasma, bilateral cavernous sinus invasion, and hydrocephalus. His thyrotrope, corticotrope, and gonadotrope axes were deficient. Surgery, somatostatin analogs, and cabergoline did not control vertical growth and pegvisomant was added, although vertical growth continues (currently 207 cm at 11 years 7 months of age). X-LAG syndrome is a new genomic disorder in which early-onset pituitary tumorigenesis can lead to marked overgrowth and gigantism. This case illustrates the aggressive nature of tumor evolution and the challenging clinical management in X-LAG syndrome. PMID:26607152

We report five patients with CD4+ DLBCL and one CD4+ primary mediastinal large B-cell lymphoma. Cases were identified by searching the electronic database of the department; each was reviewed. Average age was 56 years. Neoplastic cells expressed CD20 (5/6 tested cases). BCL2/BCL6 expression were seen in 3/3 tested cases, suggesting a germinal center origin. Additionally, expression of T-cell antigens CD2 and CD5 was noted in 2/2 and CD7 in 1/1 tested case. CD3 was negative in all. Lymph nodes were commonly involved (67%). Patients received chemotherapy +/- radiation (6/6) and bone marrow transplant (2/6). Average survival was 44.2 mo. CD4 expression in DLBCL raises questions of lineage commitment. CD4+ DLBCL is rare; care should be exercised not to diagnose these as T-cell lymphomas. A subset behaves aggressively. PMID:27679780

  5. Pathogenesis, clinical features and pathology of chronic arsenicosis.

    Arsenicosis is a multisystem disorder, with virtually no system spared from its vicious claw; though its predominant manifestations are linked to cutaneous involvement. Cutaneous effects take the form of pigmentary changes, hyperkeratosis, and skin cancers (Bowen's disease, squamous cell carcinoma, and basal cell epithelioma). Peripheral vascular disease (blackfoot disease), hypertension, ischemic heart disease, noncirrhotic portal hypertension, hepatomegaly, peripheral neuropathy, respiratory and renal involvement, bad obstetrical outcome, hematological disturbances, and diabetes mellitus are among the other clinical features linked to arsenic toxicity. The effects are mediated principally by the trivalent form of arsenic (arsenite), which by its ability to bind with sulfhydryl groups present in various essential compounds leads to inactivation and derangement of body function. Though the toxicities are mostly linked to the trivalent state, arsenic is consumed mainly in its pentavalent form (arsenate), and reduction of arsenate to arsenite is mediated through glutathione. Body attempts to detoxify the agent via repeated oxidative methylation and reduction reaction, leading to the generation of methylated metabolites, which are excreted in the urine. Understandably the detoxification/bio-inactivation process is not a complete defense against the vicious metalloid, and it can cause chromosomal aberration, impairment of DNA repair process, alteration in the activity of tumor suppressor gene, etc., leading to genotoxicity and carcinogenicity. Arsenic causes apoptosis via free radical generation, and the cutaneous toxicity is linked to its effect on various cytokines (e.g., IL-8, TGF-beta, TNF-alpha, GM-CSF), growth factors, and transcription factors. Increased expression of cytokeratins, keratin-16 (marker for hyperproliferation) and keratin-8 and -18 (marker for less differentiated epithelial cells), can be related to the histopathological findings of hyperkeratosis

    Purpose: To determine the etiology, clinical features and outcomes of bilateral vitreous hemorrhage (VH) in children. Methods: This retrospective chart review was performed on patients with bilateral VH under the age of 18 at a tertiary eye care center in India. Data included demographics, details of history and ocular examination, reports of investigations, surgeries or other interventions performed, and final anatomical and visual outcomes. Patients were divided into two groups i.e., traumatic and non-traumatic (spontaneous). Results: The traumatic group was comprised of 37 patients including 27 male and 10 female subjects with mean age of 13.47 ± 5.31 years, the most common complaint was decreased vision (96.45%) and the most prevalent etiology was firecracker injury in 16 (43.2%) patients. Mean baseline visual acuity (VA) was 2.34 ± 1.31 logMAR which was significantly improved to 1.08 ± 0.23 logMAR (P = 0.042). The mean number of surgeries was 2.72 ± 1.43 in the traumatic VH and mean follow up period was 23.14 ± 6.54 months. The spontaneous group included 48 subjects comprised of 27 male and 21 female cases with mean age of 14.48 ± 2.03 years. The most common cause was vasculitis in 21 (43.75%) subjects including four patients with tuberculosis. Mean baseline VA was 1.97 ± 1.13 logMAR which showed a significant improvement to 0.82 ± 0.24 logMAR (P = 0.012) after mean follow up of 34.2 ± 11.2 months. Eleven patients required at least one major surgery. Conclusion: Vasculitis was the most common cause of spontaneous bilateral VH; traumatic VH most prevalently occurred due to firecracker injury. Final VA was better in the spontaneous group. PMID:26425315

    Purpose: Early presentation of rejection facilitates early initiation of treatment which can favor a reversible rejection and better outcome. We analyzed the incidence, clinical features including rejection-treatment period and outcomes following graft rejection in our series of pediatric corneal graft. Materials and Methods: Case records of pediatric penetrating keratoplasty (PK) were reviewed retrospectively, and parameters noted demographic profile, indication of surgery, surgery-rejection period, rejection-treatment interval, graft outcome, and complications. Results: PK was performed in 66 eyes of 66 children <12 years, with an average follow-up of 21.12 ± 11.36 months (range 4-48 month). The median age at the time of surgery was 4.0 years (range 2 months to 12 years). Most of the children belonged to rural background. Scarring after keratitis (22, 33.4%) was the most common indication. Graft rejection occurred in eight eyes (12.12%) (acquired nontraumatic - 3, congenital hereditary endothelial dystrophy [CHED] - 2, nonCHED - 1, congenital glaucoma - 1, regraft - 1). The mean surgery-rejection period was 10.5 ± 7.3 months and mean rejection-treatment interval was 10.9 ± 7.02 days. Conclusion: This study showed irreversible graft rejection was the leading cause of graft failure of pediatric PK. Though, the incidence (12.1%) of graft rejection in current study was not high, but the percentage of reversal (25%) was one of the lowest in literature because of delayed presentation and longer interval between corneal graft rejection and treatment. In addition, categorization of the type of graft rejection was very difficult and cumbersome in pediatric patients. PMID:25709272

    AIM: To determine the causes and characteristics of fecal incontinence in men and to compare these features with those presented by a group of women with the same problem. METHODS: We analyzed the medical history, clinical and manometric data from 119 men with fecal incontinence studied in our unit and compared these data with those obtained from 645 women studied for the same problem. Response to treatment was evaluated after 6 mo of follow-up. RESULTS: Fifteen percent of patients studied in our unit for fecal incontinence were male. Men took longer than women before asking for medical help. Ano-rectal surgery was the most common risk factor for men related to fecal incontinence. Chronic diarrhea was present in more than 40% of patients in both groups. Decreased resting and external anal sphincter pressures were more frequent in women. No significant differences existed between the sexes regarding rectal sensitivity and recto-anal inhibitory reflex. In 17.8% of men, all presenting soiling, manometric findings did not justify fecal incontinence. Response to treatment was good in both groups, as 80.4% of patients improved and fecal incontinence disappeared in 13.2% of them. CONCLUSION: In our series, it was common that men waited longer in seeking medical help for fecal incontinence. Ano-rectal surgery was the major cause of this problem. Chronic diarrhea was a predisposing factor in both sexes. Manometric differences between groups were limited to an increased frequency of hypotony of the external anal sphincter in women. Fecal incontinence was controllable in most patients. PMID:24976729

    Abstract Cases of membranous nephropathy (MN) with crescent formation, in the absence of lupus, hepatitis B virus infection, anti-glomerular basement membrane (GBM) nephritis, or antineutrophil cytoplasmic antibody (ANCA), are on record. Clinical presentation and treatment outcomes in these patients are unclear. All patients with biopsy-proven MN diagnosed between years 2008 and 2014 and followed up were enrolled retrospectively. Patients with ANCA, anti-GBM antibodies, lupus, hepatitis B virus infection, or malignance were excluded. Clinical features and outcomes were compared between MN patients with and without crescent. Out of 401 consecutive patients with idiopathic MN, 28 (6.9%) showed crescent formation in 4.9% (2.2%–16.7%) of glomeruli. Mean age of these patients was 50.1 ± 11.1 years, and they presented with heavy proteinuria (6.5 ± 4.8 g/24 h) and hematuria; 21.4% of these patients had declined estimated glomerular filtration rate (<60 mL/min/1.73 m2) on biopsy. Anti-phospholipase A2 receptor antibody was detectable in 79.7% of these patients. These clinical features were comparable to the MN patients without crescent (P > 0.05). Twelve (42.9%) patients received steroids plus immunosuppressive therapy similar to that in patients without crescent (41.3%). Fewer patients with crescents achieved remission (67.9% vs 86.7%, P = 0.029). Crescent formation was a risk factor for no response to the treatments (odds ratio [OR] = 3.1, P = 0.033). Higher percentage of crescents predicted more risk for no remission (OR = 1.2, P = 0.038). Patients with crescents presented more frequencies of abnormal serum creatinine during follow-up (10.7% vs 1.3%, P = 0.031). Crescent formation was also a risk factor for worse renal outcome (relative risk = 10.2, P = 0.046). MN patients with crescents showed unfavorable therapeutic response and tended to have worse renal outcomes. More aggressive treatments and renal protection

    2014-01-01

    Background This study aimed to better understand the supporting role that mutational profiling (MP) of DNA from microdissected cytology slides and supernatant specimens may play in the diagnosis of malignancy in fine-needle aspirates (FNA) and biliary brushing specimens from patients with pancreaticobiliary masses. Methods Cytology results were examined in a total of 30 patients with associated surgical (10) or clinical (20) outcomes. MP of DNA from microdissected cytology slides and from discarded supernatant fluid was analyzed in 26 patients with atypical, negative or indeterminate cytology. Results Cytology correctly diagnosed aggressive disease in 4 patients. Cytological diagnoses for the remaining 26 were as follows: 16 negative (9 false negative), 9 atypical, 1 indeterminate. MP correctly determined aggressive disease in 1 false negative cytology case and confirmed a negative cytology diagnosis in 7 of 7 cases of non-aggressive disease. Of the 9 atypical cytology cases, MP correctly diagnosed 7 as positive and 1 as negative for aggressive disease. One specimen that was indeterminate by cytology was correctly diagnosed as non-aggressive by MP. When first line malignant (positive) cytology results were combined with positive second line MP results, 12/21 cases of aggressive disease were identified, compared to 4/21 cases identified by positive cytology alone. Conclusions When first line cytology results were uncertain (atypical), questionable (negative), or not possible (non-diagnostic/indeterminate), MP provided additional information regarding the presence of aggressive disease. When used in conjunction with first line cytology, MP increased detection of aggressive disease without compromising specificity in patients that were difficult to diagnose by cytology alone.

    We report the first case of primary solid pseudopapillary tumor of the ovary with aggressive behavior and fatal outcome in a 45-year-old woman. The patient presented with weight loss, decrease of appetite, and abdominal bloating for the last several weeks. Computed tomography scan revealed an ovarian mass, omental caking, complex ascites, and 2 hepatic lesions. The pancreas was unremarkable. Grossly, the ovarian mass showed severe capsular adhesion, and the cut surface was cystic and solid. On histologic examination, the tumor was composed of diffuse solid pseudopapillary and pseudocystic patterns. The neoplastic cells were uniform and round with very dispersed chromatin. The cytoplasm was faintly pink. There was mild atypia, but the mitotic rate was as high as 62 per 50 high-power field, and the Ki-67 was elevated at 20%. The tumor exhibited severe necrosis. Numerous foci of lymphovascular invasion were also seen. The tumor cells were positive for cytokeratin (focal) and for β-catenin (cytoplasmic and nuclear patterns). They were negative for chromogranin, synaptophysin, thyroglobulin, calcitonin, hepatocyte-paraffin 1, epithelial membrane antigen, calretinin, and α-inhibin. Electron microscopic study revealed nests of tumor cells with oval nuclei. The cytoplasm contained numerous pleomorphic mitochondria interspersed among short strands of rough endoplasmic reticulum. The tumor involved the fallopian tube, omentum, cul-de-sac, and abdominal wall. The pelvic washing was also positive for tumor cells. Despite chemotherapy, the patient's condition had worsened, and she died of her disease 8 months after the initial diagnosis. We discuss the differential diagnosis of this tumor and the hypothesis of its origin. PMID:21778097

    Strong evidence indicates that tumor growth can be actively controlled by the immune system, and interleukins (ILs) are known to play an influential role in immune response regulation. Moreover, inflammatory cytokines are significantly involved in lymphoma pathogenesis. We aimed to investigate serum levels of IL-4 and IL-18 in aggressive non-Hodgkin's lymphoma (A-NHL) patients and their relationship with prognostic parameters and therapy outcome. These serum factors were measured by enzyme-linked immunosorbent assay in 46 patients with pathologically verified A-NHL before and after chemotherapy, and in 20 healthy controls. No significant difference in serum IL-4 (P = 0.11) and IL-18 (P = 0.261) levels was observed between the A-NHL and controls groups. None of the prognostic parameters analyzed significantly correlated with serum IL-4 concentration, while only lactate dehydrogenase (LDH) measurements were associated with IL-18 values. Serum IL-18 was elevated in the patients with high LDH levels compared to those exhibiting normal values (P = 0.045). In addition, no correlation was found between the concentrations of serum IL-4 and IL-18 in A-NHL patients (r = 0.188, P = 0.187). While IL-18 values did not change, serum IL-4 levels decreased following chemotherapy, independently from treatment response (P = 0.002). Our study is the first to report the response of serum IL-4 levels to chemotherapy. In conclusion, although IL-4 serum concentration has no diagnostic role, it is sensitivite to standard chemotherapy in A-NHL. However, serum IL-18 measurements have no diagnostic or prognostic role in this disease. PMID:27525895

    The purpose of this three-year, prospective, follow-up study was to evaluate whether aggressive gap arthroplasty is essential in the management of ankylosis of the temporomandibular joint (TMJ). Fifteen patients were treated by the creation of a minimal gap of 5-8mm and insertion of an interpositional gap arthroplasty using the temporalis fascia. Eleven patients had unilateral coronoidectomy and 4 bilateral coronoidectomy based on Kaban's protocol. Preoperative assessment included recording of history, clinical and radiological examinations, personal variables, the aetiology of the ankylosis, the side affected, and any other relevant findings. Patients were assessed postoperatively by a surgeon unaware of the treatment given for a minimum of 3 years, which included measurement of the maximal incisal opening, presence of facial nerve paralysis, recurrence, and any other relevant findings. Of the 15 patients (17 joints), 12 had unilateral and three had bilateral involvement, with trauma being the most common cause. The patients were aged between 7 and 29 years (mean (SD) age 20 (8) years). Preoperative maximal incisal opening was 0-2mm in 8 cases and 2-9mm in 9. Postoperatively adequate mouth opening of 30-40mm was achieved in all cases, with no recurrence or relevant malocclusion during 3-year follow up. However, patients will be followed up for 10 years. Aggressive gap arthroplasty is not essential in the management of ankylosis of the TMJ. Minimal gap interpositional arthroplasty with complete removal of the mediolateral ankylotic mass is a feasible and effective method of preventing recurrence. PMID:23219020

    A solid pseudopapillary tumor (SPT) is a pancreatic neoplasm of low malignant potential. The potentially malignant pathologic features of SPTs were regarded as angioinvasion, perineural invasion, deep invasion of the surrounding acinar tissue, and nuclear pleomorphism. We retrospectively reviewed 31 cases of SPTs (25 female and 6 male patients, with an average age of 35 ± 14 years). The mean follow-up period was 132.0 ± 55.9 months. To evaluate the clinical impact of above pathological parameters, we analyzed their correlation with actually observed clinical malignancy. In three cases, the SPTs were clearly clinically malignant: one patient had recurrences three times, one showed lymph node metastases, and one deep soft tissue invasion around the gastroduodenal artery. Tumor infiltration to the peripancreatic soft tissue was observed in 17 cases (54.8%). The pathologic features considered suggestive of malignant potential were angioinvasion (25.8%), perineural invasion (6.5%), presence of mitosis in 10 high-power fields (16.1%), and moderate nuclear pleomorphism (19.4%). The presence of at least three of these features was not correlated with clinically confirmed malignant behavior (P = 0.570). Microscopic pathologic features of SPTs cannot be reliably associated with aggressive clinical behavior. Moreover, the absence of these microscopic features cannot exclude clinical malignancy.

    Background: Aggressive periodontitis is a characterized by rapid attachment loss, bone destruction and familial aggregation. Platelet-rich plasma (PRP) has been proposed to promote regeneration of the lost periodontal tissues. The aim of this study was to evaluate and compare the efficacy of PRP combined with hydroxyapatite (HA) graft in the treatment of intra-bony defects in localized aggressive periodontitis (L-AgP) patients. Materials and Methods: Ten L-AgP patients having bilateral intra-bony defect ≥2 mm and probing depth (PD) ≥6 mm were randomly treated either with the PRP/HA graft or HA graft alone. The clinical (plaque control record, bleeding on probing index, PD, and relative attachment level [RAL]), and radiographic parameters (size of the bone defect) were recorded pre- and post-operatively at 3, 6, and 12 months. Results: After 12 months, for both maxillary and mandibular arches, the mean PD decrease was significantly more (P < 0.05) for the test group than the control group (3.2 mm vs. 1.9 mm and 3.6 mm vs. 1.9 mm, respectively). Furthermore, the mean RAL decrease in both maxillary and mandibular arches was significantly more (P < 0.05) for the test group than the control group (3.0 mm vs. 1.2 mm and 3.1 mm vs. 1.4 mm, respectively). Radiographically, the test group showed significantly more defect fill as compared with the control group. Conclusion: Both treatments provided significant improvements in clinical and radiographic parameters in a 12-month postoperative period. PRP/HA group presented superior results regarding PD reduction, clinical attachment gain and radiographic bone fill than HA group. PMID:25395757

    Tumefactive multiple sclerosis is an inflammatory demyelinating disease of the central nervous system. It has recently been described as a rare subtype of multiple sclerosis (MS) characterised by the appearance of solitary or multiple space-occupying lesions associated with imaging characteristics mimicking neoplasm. Atypical features include plaque size >2 cm with mass effect, oedema, and/or ring enhancement on magnetic resonance (MR) images.This study is a retrospective review designed to evaluate the prevalence of tumefactive plaques in a selected population of 440 MS patients referred to our MS centre in Southern Italy between 2005 and 2014. We analysed the radiographic features of lesions ranging in size from 0.5 to 2 cm to establish whether smaller plaques with MR characteristics similar to tumefactive plaques present different symptoms, disease evolution and prognosis. We also aimed to ascertain if MR features suggestive of biological aggressiveness could be useful prognostic criteria for a correct diagnosis of the disease and subsequent treatment. Our data suggest that lesions 0.5-2 cm and >2 cm have similar MR features and clinical evolution.

    The aim of the project was to evaluate the clinical value of a computer analysis of cytological specimen images obtained from urine and bladder washing samples. Three sample types (voided urine, catheterized urine and bladder washing) from 59 patients with primary or recurrent tumor were analyzed. All patients underwent cystoscopy and biopsy or resection. The histological results were compared with the results of the image analyzing computer system of collected urine samples. The consistency between the computer diagnosis and the clinical or histological diagnosis both in the presence and absence of cancer was as follows: 77% for voided urine samples, 72.5% for catheterized urine samples and 78% for bladder washing samples. The specificity of the method at the standard pathology level was 71%, and the sensitivity was 83%. The positive and negative predictive values (PPV and NPV) were 87.5% and 63% respectively. The sensitivity for G3 or CIS or T2 or T3 tumors reached nearly 100%. Computer analysis of urine provided correct diagnoses in cancer and control patients with the sensitivity of 83% and specificity of 71% and gave excellent results in aggressive tumors such as T2, T3, G3 and in CIS.

    Vitamin D plays crucial roles in neuroprotection and neurodevelopment, and low levels are commonly associated with schizophrenia. We considered if the association was spurious or causal by examining the association of Vitamin D with Leukocyte Telomere Length (LTL), a marker of cellular aging. Vitamin D levels in 22 well-characterized schizophrenia cases were examined with respect to symptoms, cognition, and functioning. LTL was assessed using quantitative polymerase chain reaction (qPCR). The results showed that 91% (20) had deficient or insufficient Vitamin D levels, which were associated with excitement and grandiosity, social anhedonia, and poverty of speech. Sex-specific analyses showed strong associations of hypovitamintosis D to negative symptoms and decreased premorbid adjustment in males, and to lesser hallucinations and emotional withdrawal, but increased anti-social aggression in females. In females LTL was furthermore associated with Vitamin D levels. This study demonstrates a relationship of low vitamin D levels with increased cellular aging in females. It is also the first study to demonstrate potential sex-specific profiles among schizophrenia cases with hypovitaminosis.

    Despite a flurry of studies examining psychopathy in women, and the recent release of the second version of the Hare Psychopathy Checklist--Revised manual, there is still little consensus whether the lateral extension of the current conceptualization of psychopathy to women is appropriate. In particular, very little agreement exists concerning the clinical utility of the Hare psychopathy measures to assess women's risk of future offending and violence. This article presents a comprehensive review of studies of the association between psychopathy, antisocial behavior, and violence, in diverse samples of women, and looks at similarities and differences between these constructs in males and females. Findings from inmates and offenders, civil and forensic psychiatric patients, substance abusers, and community samples indicate a consistently lower base rate of psychopathy among women than among men. With some exceptions, correlates of psychopathy in women relevant to risk assessments for crime and violence tend to be modest and significant, generally mirroring what we see in men. Clinicians and policy makers charged with the care and management of women at risk for criminal offending and violence are likely to find the PCL-R and PCL:SV have clinical utility; however, cautious application is called for and ongoing research is required.

    Background The management of disruptive neuropsychiatric symptom (NPS) such as agitation and aggression (A/A) is a major priority in caring for people with Alzheimer’s disease (AD). Few effective pharmacological or non-pharmacological options are available. Results of randomized clinical trials (RCTs) of drugs for A/A have been disappointing. This may result from the absence of biological efficacy for medications tested in treating A/A. It may also be related to methodological issues such as the choice of outcomes. The aim of this review was to highlight key methodological issues pertaining to RCTs of current and emerging medications for the treatment of A/A in AD. Methods We searched PubMed/Medline, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov for RCTs comparing medications with either placebo or other drugs in the treatment of A/A in AD, between January 2008 and December 2013. Results We identified a total of 18 RCTs; of these, 11 were completed and 7 ongoing. Of the ongoing RCTs, only one is in Phase III. Seven of 10 completed RCTs with reported results did not report greater benefit from drug than placebo. Each of the completed RCTs used a different definition of “clinically significant A/A”. There was considerable heterogeneity in study desin. The primary endpoints were largely proxy-based but a variety of scales were used. The definition of caregiver and scales used to assess caregiver outcomes were similarly heterogeneous. Placebo response was notable in all trials. Conclusions This review highlights a great heterogeneity in RCTs design of drugs for A/A in AD and some key methodological issues such as definition of A/A, choice of outcome measures and caregiver participation that could be addressed by an expert consensus to optimize future trials design.

    4 patients below the age of 20 years have been treated for a malignant tumor of the ovary during the period November 1, 1984 until April 30, 1988. Dysgerminoma was the diagnosis in two cases, as the third patient suffered from a bilateral malignant teratoma. Burkitt's Lymphoma involved both ovaries primarily in an 17-year-old girl. Retrospectively we analyzed diagnosis, therapy and clinical course of these young patients. Regarding the different histological types of the tumors that have been found we discuss critically current recommendations in therapeutic managements referring chemotherapy and/or radiotherapy. Defined conditions provided surgical treatment, that preserves fertility in early stages of malignant germ cell tumors of adolescent women, may be justified, especially for dysgerminomas. A real benefit relate to survival and quality of life by using chemotherapeutic agents can only be expected, if all prognostic factors are regarded.

    The purpose of our investigation was to study gender differences in proactive and reactive aggression in a sample of 323 clinically referred children and adolescents (68 females and 255 males). Proactive aggression and reactive aggression were assessed using the Proactive/Reactive Aggression Scale. Demographic, historical, family, diagnostic, and treatment variables were entered into stepwise regression analyses to determine correlates of proactive and reactive aggression in males and females. Results reveal high rates of aggression in both males and females in the sample. Self reported drug use, expressed hostility, and experiences of maladaptive parenting were correlated with proactive aggression for both genders. Hyperactive/impulsive behaviors were correlated with male reactive aggression. An early age of traumatic stress and a low verbal IQ were correlated with female proactive aggression. Gender differences in correlates of proactive and reactive aggression may provide possible targets for research, prevention, and treatment efforts focused on reducing maladaptive aggression in clinically referred youth.

    Protein Tyrosine Phosphatase Receptor J (PTPRJ) has been reported to be a tumor suppressor in various human cancers. The aim of this study was to investigate the clinical significance of PTPRJ in ESCC patients and its effects on biological behaviors of ESCC cells. PTPRJ expression, at mRNA and protein levels, were respectively detected by quantitative real-time PCR, western blot and immunohistochemistry, based on 106 newly diagnosed ESCC patients. The associations between PTPRJ expression and clinicopathological characteristics of ESCC patients were statistically analyzed. Then, the effects of PTPRJ in migration and invasion were determined by wound healing and transwell assays based on ESCC cell line transfected with siRNA or expression vector of PTPRJ. Expression of PTPRJ at mRNA and protein levels were both significantly lower in ESCC tissues than those in normal esophageal mucosa. Immunohistochemistry showed that PTPRJ protein was localized in the cytoplasm of cancer cells in ESCC tissues. In addition, PTPRJ downregulation was found to be closely correlated with advanced tumor stage (P = 0.01) and poor differentiation (P = 0.03). Moreover, knockdown of PTPRJ in KYSE510 cells could significantly promote cell migration and invasion (both P < 0.05), which were reversed by the restoration of PTPRJ expression in vitro (both P < 0.05). Our data offer the convincing evidence that loss of PTPRJ expression may predict an aggressive clinical course in ESCC patients. PTPRJ may function as a tumor suppressor and play an important role in the regulation of ESCC cell motility, suggesting its potentials as a therapeutic agent for human ESCC.

    2011-01-01

    Dementia is a clinical syndrome of widespread progressive deterioration of cognitive abilities and normal daily functioning. These cognitive and behavioral impairments pose considerable challenges to individuals with dementia, along with their family members and caregivers. Four primary dementia classifications have been defined according to clinical and research criteria: 1) Alzheimer’s disease; 2) vascular dementias; 3) frontotemporal dementias; and 4) dementia with Lewy bodies/Parkinson’s disease dementia. The cumulative efforts of multidisciplinary healthcare teams have advanced our understanding of dementia beyond basic descriptions, towards a more complete elucidation of risk factors, clinical symptoms, and neuropathological correlates. The characterization of disease subtypes has facilitated targeted management strategies, advanced treatments, and symptomatic care for individuals affected by dementia. This review briefly summarizes the current state of knowledge and directions of dementia research and clinical practice. We provide a description of the risk factors, clinical presentation, and differential diagnosis of dementia. A summary of multidisciplinary team approaches to dementia care is outlined, including management strategies for the treatment of cognitive impairments, functional deficits, and behavioral and psychological symptoms of dementia. The needs of individuals with dementia are extensive, often requiring care beyond traditional bounds of medical practice, including pharmacologic and non-pharmacologic management interventions. Finally, advanced research on the early prodromal phase of dementia is reviewed, with a focus on change-point models, trajectories of cognitive change, and threshold models of pathological burden. Future research goals are outlined, with a call to action for social policy initiatives that promote preventive lifestyle behaviors, and healthcare programs that will support the growing number of individuals affected by

    Sarcoidosis has innumerable clinical manifestations, as the disease may affect every body organ. Furthermore, the severity of sarcoidosis involvement may range from an asymptomatic state to a life-threatening condition. This manuscript reviews a wide variety of common and less common clinical characteristics of sarcoidosis. These manifestations are presented organ by organ, although additional sections describe systemic and multiorgan presentations of sarcoidosis. The lung is the organ most commonly involved with sarcoidosis with at least 90 % of sarcoidosis patients demonstrating lung involvement in most series. The skin, eye, liver, and peripheral lymph node are the next most commonly clinically involved organs in most series, with the frequency of involvement ranging from 10 to 30 %. The actual frequency of sarcoidosis organ involvement is probably much higher as it is frequently asymptomatic and may avoid detection. This is particularly common with lung, liver, cardiac, and bone involvement. Cardiac sarcoidosis is present in 25 % of all sarcoidosis but only causes clinical problems in 5 % of them. Nevertheless, unlike sarcoidosis involvement of most other organs, it may be suddenly fatal. Therefore, it is important to screen for cardiac sarcoidosis in all sarcoidosis patients. All sarcoidosis patients should also be screened for eye involvement as asymptomatic patients may have eye involvement that may cause permanent vision impairment. Pulmonary fibrosis from sarcoidosis is usually slowly progressive but may be life-threatening because of the development of respiratory failure, pulmonary hypertension, or hemoptysis related to a mycetoma or bronchiectasis. Some manifestations of sarcoidosis are not organ-specific and probably are the result of a release of mediators from the sarcoid granuloma. Two such manifestations include small fiber neuropathy and fatigue syndromes, and they are observed in a large percentage of patients.

    2015-01-01

    Alport syndrome is an inherited disease characterized by progressive renal failure, hearing loss, and ocular abnormalities. Mutations in the COL4A5 (X-linked), or COL4A3 and COL4A4 (autosomal recessive) genes result in absence of the collagen IV α3α4α5 network from the basement membranes of the cornea, lens capsule, and retina and are associated with corneal opacities, anterior lenticonus, fleck retinopathy, and temporal retinal thinning. Typically, these features do not affect vision or, in the case of lenticonus, are correctable. In contrast, the rarer ophthalmic complications of posterior polymorphous corneal dystrophy, giant macular hole, and maculopathy all produce visual loss. Many of the ocular features of Alport syndrome are common, easily recognizable, and thus, helpful diagnostically, and in identifying the likelihood of early-onset renal failure. Lenticonus and central fleck retinopathy strongly suggest the diagnosis of Alport syndrome and are associated with renal failure before the age of 30 years, in males with X-linked disease. Sometimes, ophthalmic features suggest the mode of inheritance. A peripheral retinopathy in the mother of a male with hematuria suggests X-linked inheritance, and central retinopathy or lenticonus in a female means that recessive disease is likely. Ocular examination, retinal photography, and optical coherence tomography are widely available, safe, fast, inexpensive, and acceptable to patients. Ocular examination is particularly helpful in the diagnosis of Alport syndrome when genetic testing is not readily available or the results are inconclusive. It also detects complications, such as macular hole, for which new treatments are emerging. PMID:25649157

    Purpose. Primary hemorrhage in the ventricular system without a recognizable parenchymal component is very rare. This single-center retrospective study aimed to further characterize the clinical characteristics and early outcome of this stroke subtype. Methods. All patients with primary intraventricular hemorrhage included in a prospective hospital-based stroke registry over a 19-year period were assessed. A standardized protocol with 161 items, including demographics, risk factors, clinical data, neuroimaging findings, and outcome, was used for data collection. A comparison was made between the groups of primary intraventricular hemorrhage and subcortical intracerebral hemorrhage. Predictors of primary intraventricular hemorrhage were identified by logistic regression analysis. Results. There were 12 patients with primary intraventricular hemorrhage (0.31% of all cases of stroke included in the database) and 133 in the cohort of subcortical hemorrhage. Very old age (≥85 years) (odds ratio (OR) 9.89), atrial fibrillation (OR 8.92), headache (OR 6.89), and altered consciousness (OR 4.36) were independent predictors of intraventricular hemorrhage. The overall in-hospital mortality rate was 41.7% (5/12) but increased to 60% (3/5) in patients aged 85 years or older. Conclusion. Although primary intraventricular hemorrhage is uncommon, it is a severe clinical condition with a high early mortality. The prognosis is particularly poor in very old patients.

    Introduction Data specific to late-life bipolar disorder (BD) are limited. Current research is sparse and present guidelines are not adapted to this group of patients. Objectives We present a literature review on clinical characteristics, comorbidities, and cognitive impairment in patients with late-life BD. This review discusses common comorbidities that affect BD elders and how aging might affect cognition and treatment. Methods Eligible studies were identified in MedLine by the Medical Subject Headings terms “bipolar disorder” and “aged”. We only included original research reports published in English between 2012 and 2015. Results From 414 articles extracted, 16 studies were included in the review. Cardiovascular and respiratory conditions, type II diabetes, and endocrinological abnormalities were observed as highly prevalent. BD is associated with a high suicide risk. Bipolar elderly had an increased risk of dementia and performed worse on cognitive screening tests compared to age-matched controls across different levels of cognition. Despite high rates of medical comorbidity among bipolar elderly, a systematic under-recognition and undertreatment of cardiovascular disease have been suggested. Conclusion There was a high burden of physical comorbidities and cognitive impairment in late-life BD. Bipolar elderly might be under-recorded and undertreated in primary medical care, indicating that this group needs an adapted clinical assessment and specific clinical guidelines need to be established.

    The clinical manifestations associated with H5N1 infection in humans range from asymptomatic infection to mild upper respiratory illness, severe pneumonia, and multiple organ failure. The ratio of symptomatic cases to asymptomatic cases is not known, because it is not possible to precisely define the number of asymptomatic cases. A total of 97 cases suffering from avian flu were suspected based on history taking, demographic data, clinical manifestations, laboratory and radiological investigations. The followings were done for all cases; complete blood picture (differential leucocytic count), coagulation profile, renal and liver function tests. H5N1 influenza virus was diagnosed thorough PCR technique. Changes in arterial blood gases and repeated chest X-rays were reported frequently. All patients were given specific antiviral therapy (oseltamivir). The study described the clinical picture and laboratory results of 81 confirmed avian influenza human cases in an Egyptian hospital (Abassia chest hospital), and reviewed the avian influenza current situation covering from March 2006 to June 2009 with very high pick in the first half of 2009. The significant apparent symptoms were fever as initial and main symptom (93.75%), followed by shortness of breathing (73%), cough (66.6%), muscle & joint pain (60%) and sore throat (40%).

    Basal cell carcinoma is the most common human cancer. Its incidence is steadily increasing. The development of basal cell carcinoma is linked to genetic factors, including the individual skin phototype, as well as the cumulative exposure to UVB. The vast majority of basal cell carcinomas are sporadic tumors, while familial cases associated with certain hereditary syndromes are less common. At the molecular level, basal cell carcinomas are characterized by aberrant activation of sonic hedgehog signaling, usually due to mutations either in the ptch or smoh genes. In addition, about half of the cases carry mutations in the tp53 tumor suppressor gene, which are often UVB-associated C-->T transition mutations. Clinically, basal cell carcinomas may show a high degree of phenotypical variability. In particular, tumors occurring in atypical locations, showing an unusual clinical appearance, or imitating other skin diseases may cause diagnostic problems. This review article summarizes the current state of the art concerning the etiology, predisposition and molecular genetics of basal cell carcinoma. In addition, examples of unusual clinical manifestations are illustrated. PMID:17440702

    Dermoscopic examination of hair and scalp, also named "trichoscopy," is an essential tool in diagnosis of hair and scalp diseases. Trichoscopy is fast and noninvasive and can be used to evaluate hair disorders in all body areas. Body hair disorders are uncommon, and most publications on their dermoscopic features are limited to case reports or series. In this review we present the available information on the dermoscopic diagnosis of body hair disorders including keratosis pilaris, trichostasis spinulosa, pili multigemini, circle hairs, rolled hairs, eruptive vellus hair cyst, and ingrown hairs.

    Highlights: Black-Right-Pointing-Pointer PTP1B protein showed decreased expression in 67.79% of the HCC patients. Black-Right-Pointing-Pointer Low PTP1B expression predicts poor prognosis of HCC. Black-Right-Pointing-Pointer Low PTP1B expression is correlated with expansion of OV6{sup +} tumor-initiating cells. Black-Right-Pointing-Pointer Down-regulation of PTP1B is associated with activation of Wnt/{beta}-Catenin signaling. -- Abstract: The protein-tyrosine phosphatase 1B (PTP1B) is a classical non-transmembrane protein tyrosine phosphatase that plays a key role in metabolic signaling and can exert both tumor suppressing and tumor promoting effects in different cancers depending on the substrate involved and the cellular context. However, the expression level and function of PTP1B in hepatocellular carcinoma (HCC) remain unclear. In this study, PTP1B expression was detected by immunohistochemistry in normal liver tissue (n = 16) and hepatocellular carcinoma (n = 169). The correlations between PTP1B expression level and clinicopathologic features and patient survival were also analyzed. One hundred and eleven of 169 HCC patients (65.7%) had negative or low PTP1B expression in tumorous tissues, whereas normal tissues always expressed strong PTP1B. Decreased PTP1B expression was significantly associated with aggressive clinicopathologic features and poor prognosis. Immunohistochemistry also showed that low PTP1B expression level was correlated with high percentage of OV6{sup +} tumor-initiating cells (T-ICs) and high frequency of nuclear {beta}-Catenin expression in HCC specimens. Our findings demonstrate for the first time that the loss of inhibitory effect of PTP1B may contribute to progression and invasion of HCC through activation of Wnt/{beta}-Catenin signaling and expansion of liver T-ICs. PTP1B may serve as a valuable prognostic biomarker and potential therapeutic target in HCC.

    Colorectal cancer (CRC) is one of the leading causes of cancer related mortality worldwide. Although young-onset CRC raises the possibility of a hereditary component, hereditary CRC syndromes only explain a minority of young-onset CRC cases. There is evidence to suggest that young-onset CRC have a different molecular profile than late-onset CRC. While the pathogenesis of young-onset CRC is well characterized in individuals with an inherited CRC syndrome, knowledge regarding the molecular features of sporadic young-onset CRC is limited. Understanding the molecular mechanisms of young-onset CRC can help us tailor specific screening and management strategies. While the incidence of late-onset CRC has been decreasing, mainly attributed to an increase in CRC screening, the incidence of young-onset CRC is increasing. Differences in the molecular biology of these tumors and low suspicion of CRC in young symptomatic individuals, may be possible explanations. Currently there is no evidence that supports that screening of average risk individuals less than 50 years of age will translate into early detection or increased survival. However, increasing understanding of the underlying molecular mechanisms of young-onset CRC could help us tailor specific screening and management strategies. The purpose of this review is to evaluate the current knowledge about young-onset CRC, its clinicopathologic features, and the newly recognized molecular alterations involved in tumor progression.

    Background. Buruli ulcer, caused by Mycobacterium ulcerans, is a necrotizing skin disease leading to extensive cutaneous and subcutaneous destruction and functional limitations. Spontaneous healing in the absence of medical treatment occurs in rare cases, but this has not been well described in the literature. Methods. In a retrospective case study in an area of Benin where this disease is highly endemic, we selected 26 Buruli ulcer patients presenting features of spontaneous healing from a cohort of 545 Buruli ulcer patients treated between 2010 and 2013. Results. The 26 patients studied had a median age of 13.5 years and were predominantly male (1.4:1). Three groups of patients were defined on the basis of their spontaneous healing characteristics. The first group (12 patients) consisted of patients with an ulcer of more than 1 year′s duration showing signs of healing. The second (13 patients) group contained patients with an active Buruli ulcer lesion some distance away from a first lesion that had healed spontaneously. Finally, the third group contained a single patient displaying complete healing of lesions from a nodule, without treatment and with no relapse. Conclusions. We defined several features of spontaneous healing in Buruli ulcer patients and highlighted the difficulties associated with diagnosis and medical management. Delays in consultation contributed to the high proportion of patients with permanent sequelae and a risk of squamous cell carcinoma. Early detection and antibiotic treatment are the best ways to reduce impairments. PMID:26925431

    IMPORTANCE Lewy bodies are a frequent coexisting pathology in late-onset Alzheimer disease (AD). Previous studies have examined the contribution of Lewy bodies to the clinical phenotype of late-onset AD with variable findings. OBJECTIVE To determine whether the presence of Lewy body pathology influences the clinical phenotype and progression of symptoms in longitudinally assessed participants with AD. DESIGN, SETTING, AND PARTICIPANTS Retrospective clinical and pathological cohort study of 531 deceased participants who met the neuropathologic criteria for intermediate or high likelihood of AD according to the National Institute on Aging–Ronald Reagan Institute guidelines for the neuropathologic diagnosis of AD. All participants had a clinical assessment within 2 years of death. The data were obtained from 34 AD centers maintained by the National Alzheimer Coordinating Center and spanned from September 12, 2005, to April 30, 2013. EXPOSURES Standardized neuropathologic assessment and then brain autopsy after death. MAIN OUTCOMES AND MEASURES Clinical and neuropsychiatric test scores. RESULTS The mean (SD) age at death was statistically significantly younger for participants who had AD with Lewy bodies (77.9 [9.5] years) than for participants who had AD without Lewy bodies (80.2 [11.1] years) (P = .01). The mean (SD) age at onset of dementia symptoms was also younger for participants who had AD with Lewy bodies (70.0 [9.9] years) than for participants who had AD without Lewy bodies (72.2 [12.3] years) (P = .03). More men than women had AD with Lewy bodies (P = .01). The frequency of having at least 1 APOE ε4 allele was higher for participants who had AD with Lewy bodies than for participants who had AD without Lewy bodies (P = .03). After adjusting for age, sex, education, frequency of plaques (neuritic and diffuse), and tangle stage, we found that participants who had AD with Lewy bodies had a statistically significantly higher mean (SD) Neuropsychiatric

    Background In June 2014, Suriname faced the first Chikungunya outbreak. Since international reports mostly focus on hospitalized patients, the least affected group, a study was conducted to describe clinical characteristics of mainly outpatients including children. In addition, the cumulative incidence of this first epidemic was investigated. Methodology During August and September 2014, clinically suspected Chikungunya cases were included in a prospective follow-up study. Blood specimens were collected and tested for viral RNA presence. Detailed clinical information was gathered through multiple telephone surveys until day 180. In addition, a three stage household-based cluster with a cross-sectional design was conducted in October, December 2014 and March 2015 to assess the cumulative incidence. Principal Findings Sixty-eight percent of symptomatic patients tested positive for Chikungunya virus (CHIKV). Arthralgia and pain in the fingers were distinctive for viremic CHIKV infected patients. Viremic CHIKV infected children (≤12 years) characteristically displayed headache and vomiting, while arthralgia was less common at onset. The disease was cleared within seven days by 20% of the patients, while 22% of the viremic CHIKV infected patients, mostly women and elderly reported persistent arthralgia at day 180. The extrapolated cumulative CHIKV incidence in Paramaribo was 249 cases per 1000 persons, based on CHIKV self-reported cases in 53.1% of the households and 90.4% IgG detected in a subset of self-reported CHIKV+ persons. CHIKV peaked in the dry season and a drastic decrease in CHIKV patients coincided with a governmental campaign to reduce mosquito breeding sites. Conclusions/Significance This study revealed that persistent arthralgia was a concern, but occurred less frequently in an outpatient setting. The data support a less severe pathological outcome for Caribbean CHIKV infections. This study augments incidence data available for first outbreaks in the

    Selective serotonin reuptake inhibitors (SSRIs) are widely prescribed to treat depression. Although these drugs presumably have the same mechanism of action, they vary in several clinically important ways, including how long they remain in the body and the extent to which they interfere with the metabolism of other medications. This article reviews the pharmacologic differences among SSRIs and how these differences may affect various aspects of treatment, such as dosing, administration, and discontinuation. Understanding the distinct properties of SSRIs may help primary care physicians to design the most appropriate therapeutic plan for individual patients. PMID:15014630

    We report six patients with partial, predominantly paramedian, tegmental pontine hemorrhages. Constant clinical manifestations consisted of: ipsilateral miosis, horizontal gaze paresis, lower motor neuron facial paresis, contralateral hemisensory loss and mild and transitory hemiparesis, dysarthria and mild or no compromise of consciousness. Five out of six were hypertensive. All patients survived with mild sequelae, oculomotor disturbances being the most persistent deficit. We found in our patients that a transverse diameter of less than 17 mm, unilaterality of the injury and absence of coma were the major indicators of a favorable outcome.

    Schizophrenia is a complex neuropsychiatric disorder that is associated with persistent psychosocial disability in affected individuals. Although studies of schizophrenia have traditionally focused on deficits in higher-order processes such as working memory and executive function, there is an increasing realization that, in this disorder, deficits can be found throughout the cortex and are manifest even at the level of early sensory processing. These deficits are highly amenable to translational investigation and represent potential novel targets for clinical intervention. Deficits, moreover, have been linked to specific structural abnormalities in post-mortem auditory cortex tissue from individuals with schizophrenia, providing unique insights into underlying pathophysiological mechanisms.

    Subacute care, like our health care system generally, is designed primarily to meet the needs of the adult patient. Emphasis on the adult patient, however, ignores the children who could be appropriately and cost-effectively treated at a subacute level of care. These children offer the most persuasive argument yet for broadening our perspective on subacute care beyond the adult model, but to do so means considering the special needs of children, particularly in the areas of family-centered and age-appropriate care. In this article, we draw upon experience at 2 pediatric subacute care facilities to (1) identify specific treatment programs for children; (2) identify essential features of program delivery; (3) discuss how the typical adult-centered model needs to be modified for children; and (4) offer amendments that make the current adult-centered definitions of subacute care more responsive to children's needs.

    The prevalence of human T cell lymphoma virus type 1 (HTLV-I) was studied among patients with endogenous uveitis. Twelve (15.8%) of 76 uveitis patients with known aetiology or clinical entity were seropositive, the prevalence being comparable with that in the general population of the southwestern area of Japan where HTLV-I is highly endemic. In the comparison, 32 (41.0%) of 78 patients with aetiology or entity undefined uveitis were seropositive for HTLV-I, which indicated a significantly higher seroprevalence than controls matched for sex and age. The 32 cases of clinical entity undefined, HTLV-I positive uveitis were characterised by acute granulomatous or non-granulomatous uveal reactions which were accompanied by vitreous opacities and retinal vasculitis. The uveal inflammatory and retinal vascular changes responded well to topical and/or systemic corticosteroids and resolved in a few weeks in the majority of cases with favourable visual outcome. The disease affected one or both eyes, and eight cases (25%) showed recurrence within a year. The general condition of the patients remained well otherwise during a follow up study (mean follow up time 15.4 months), except for three cases with a possible association of hyperthyroidism. These findings provide additional information favouring an association between HTLV-I and isolated uveitis, a new disease entity which should be termed HTLV-I-associated uveitis. Images PMID:8100446

    Accidental exposure to ionizing radiation may occur during such catastrophic events as the Chernobyl accident in 1986 or over days to weeks as in Goiania in 1987 and in the military camp during the training of soldiers in Lilo/Georgia in 1997, as well as in medical institutions. The cutaneous symptoms after radiation exposure are based on a combination of inflammatory processes and alteration of cellular proliferation as a result of a specific pattern of transcriptionally activated proinflammatory cytokines and growth factors. They follow a time course consisting of prodromal erythema, latency period, acute stage, chronic stage and late stage. The entire complex is referred to as cutaneous radiation syndrome. The time course depends on several factors such as the radiation dose, radiation quality, individual radiation sensitivity, the extent of contamination and absorption and amount of skin exposed. For the diagnosis of the cutaneous radiation syndrome the following procedures are used: 7.5 MHz to 20 MHz-B-scan sonography, thermography, capillary microscopy, profilometry, nuclear magnetic resonance imaging, bone scintigraphy and histology. Based on the results of experimental and clinical research, today treatment may include topical or systemic corticosteroids, gamma-interferon, pentoxifylline, vitamin E and superoxide dismutase. The treatment depends on the stage of the cutaneous radiation syndrome. Due to the complexity of the clinical manifestations of radiation disease, most patients require interdisciplinary treatment in specialized centres. Dermatologists are essential partners in the life-long follow-up and therapy of such patients.

  17. Diagnosis and clinical features of trigemino-autonomic headaches.

    PubMed

    May, Arne

    2013-10-01

    Although severe short-lasting headaches are rare, they can be considered disabling conditions with a major impact on the quality of life of patients. These headaches can divided broadly in to those associated with autonomic symptoms, so called trigeminal autonomic cephalgias (TACs), and those with few or no autonomic symptoms. The TACs include cluster headache, paroxysmal hemicranias, hemicrania continua, and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms as well as short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing syndrome. In all of these syndromes, half-sided head pain and ipsilateral cranial autonomic symptoms such as lacrimation or rhinorrhea are prominent. The paroxysmal hemicranias have, unlike cluster headaches, a very robust response to indomethacin, leading to a notion of indomethacin-sensitive headaches. The diagnosis of TACs is exclusively a clinical task. Because of the fact that cluster headache is strictly half-sided, typically involves the region around the eye and temple and often starts in the upper jaw, most patients first consult a dentist or ophthalmologist. No single instrumental examination has yet been able to define, or ensure, the correct diagnosis, or differentiate idiopathic headache syndromes. It is crucial that a trained neurologist sees these patients early so that management can be optimized and unnecessary procedures can be avoided. Although TACS are, in comparison to migraine, quite rare, they are nevertheless clinically very important for the neurologist to consider as they are easy to diagnose and the treatment is very effective in most patients.

  18. Clinical and molecular genetic features of hereditary pulmonary arterial hypertension.

    PubMed

    2011-10-01

    Pulmonary arterial hypertension (PAH) is a rare disorder that may be hereditary (HPAH), idiopathic (IPAH), or associated with either drug-toxin exposures or other medical conditions. Familial cases have long been recognised and are usually due to mutations in the bone morphogenetic protein receptor type 2 gene (BMPR2), or, much less commonly, two other members of the transforming growth factor-β superfamily, activin-like kinase-type 1 (ALK1), and endoglin (ENG), which are associated with hereditary hemorrhagic telangiectasia. In addition, approximately 20% of patients with IPAH carry mutations in BMPR2. Clinical testing for BMPR2 mutations is available and may be offered to HPAH and IPAH patients but should be preceded by genetic counselling, since lifetime penetrance is only 10% to 20%, and there are currently no known effective preventative measures. Identification of a familial mutation can be valuable in reproductive planning and identifying family members who are not mutation carriers and thus will not require lifelong surveillance. With advances in genomic technology and with international collaborative efforts, genome-wide association studies will be conducted to identify additional genes for HPAH, genetic modifiers for BMPR2 penetrance, and genetic susceptibility to IPAH. In addition, collaborative studies of BMPR2 mutation carriers should enable identification of environmental modifiers, biomarkers for disease development and progression, and surrogate markers for efficacy end points in clinical drug development, thereby providing an invaluable resource for trials of PAH prevention.

    Stress fracture, in its most inclusive description, includes both fatigue and insufficiency fracture. Fatigue fractures, sometimes equated with the term "stress fractures," are most common in runners and other athletes and typically occur in the lower extremities. These fractures are the result of abnormal, cyclical loading on normal bone leading to local cortical resorption and fracture. Insufficiency fractures are common in elderly populations, secondary to osteoporosis, and are typically located in and around the pelvis. They are a result of normal or traumatic loading on abnormal bone. Subchondral insufficiency fractures of the hip or knee may cause acute pain that may present in the emergency setting. Medial tibial stress syndrome is a type of stress injury of the tibia related to activity and is a clinical syndrome encompassing a range of injuries from stress edema to frank-displaced fracture. Atypical subtrochanteric femoral fracture associated with long-term bisphosphonate therapy is also a recently discovered entity that needs early recognition to prevent progression to a complete fracture. Imaging recommendations for evaluation of stress fractures include initial plain radiographs followed, if necessary, by magnetic resonance imaging (MRI), which is preferred over computed tomography (CT) and bone scintigraphy. Radiographs are the first-line modality and may reveal linear sclerosis and periosteal reaction prior to the development of a frank fracture. MRI is highly sensitive with findings ranging from periosteal edema to bone marrow and intracortical signal abnormality. Additionally, a brief description of relevant clinical management of stress fractures is included.

  20. Signaling aggression.

    PubMed

    van Staaden, Moira J; Searcy, William A; Hanlon, Roger T

    2011-01-01

    From psychological and sociological standpoints, aggression is regarded as intentional behavior aimed at inflicting pain and manifested by hostility and attacking behaviors. In contrast, biologists define aggression as behavior associated with attack or escalation toward attack, omitting any stipulation about intentions and goals. Certain animal signals are strongly associated with escalation toward attack and have the same function as physical attack in intimidating opponents and winning contests, and ethologists therefore consider them an integral part of aggressive behavior. Aggressive signals have been molded by evolution to make them ever more effective in mediating interactions between the contestants. Early theoretical analyses of aggressive signaling suggested that signals could never be honest about fighting ability or aggressive intentions because weak individuals would exaggerate such signals whenever they were effective in influencing the behavior of opponents. More recent game theory models, however, demonstrate that given the right costs and constraints, aggressive signals are both reliable about strength and intentions and effective in influencing contest outcomes. Here, we review the role of signaling in lieu of physical violence, considering threat displays from an ethological perspective as an adaptive outcome of evolutionary selection pressures. Fighting prowess is conveyed by performance signals whose production is constrained by physical ability and thus limited to just some individuals, whereas aggressive intent is encoded in strategic signals that all signalers are able to produce. We illustrate recent advances in the study of aggressive signaling with case studies of charismatic taxa that employ a range of sensory modalities, viz. visual and chemical signaling in cephalopod behavior, and indicators of aggressive intent in the territorial calls of songbirds.

    Benign paroxysmal positional vertigo (BPPV) is one of the common vestibular disorders. Canalolithiasis is thought to be a likely lesion. A canalith repositioning procedure (CRP by Epley) generally yields good resolution of vertigo and nystagmus. The authors confirmed the efficacy of this procedure on typical BPPV of the posterior semicircular canal type. We designed a new procedure for BPPV of the lateral canal type, which also yielded satisfactory results. BPPV sometimes presents a nystagmus pattern, which suggests multiple lesions. We have seen eight cases of BPPV showing nystagmus that combines both the posterior and the lateral canal types. Combined CRP was performed on these cases, which again gave good clinical results. Other BPPV cases were associated with central lesions. We must be aware that BPPV may involve multiple canals and may be associated with central lesions. PMID:10320057

    The authors present the results of examination of 34 patients, aged from 18 to 30 years, with attention deficit hyperactivity disorder (ADHD) (ICD-10 item F90.0). The study has shown that inattentive type of ADHD is noted in 50%, combined type in 38.3% and hyperactivity/impulsivity type in 11.7% of patients. Adult patients with ADHD also have a high level of anxiety and asthenic disorders. This study evaluated the efficacy and safety of adaptol in dosage 1500 mg daily during 8 weeks in the treatment of this group of patients. The high efficacy (improvement in 64,7% of cases) and safety of adaptol confirmed by the data of clinical, psychological and neurophysiological studies.

    A study was performed to assess differences in the clinical presentation of tuberculosis between two groups of immigrants. Ninety-four patients seen in the emergency room for newly diagnosed tuberculosis between 2006 and 2012 were included. Forty-nine patients were from Asian countries and 45 from Latin America. Mean age [years (SD)] was 35.3 (13) in Asian patients and 33.9 (10) in Latin American patients. Asian subjects were predominantly male (40/49 vs 25/45; P=0.006). Patients from Latin American countries had a higher rate of pulmonary tuberculosis. A higher percentage of Asian patients lived in overcrowded conditions, whereas HIV infection was more frequent among Latin Americans. Most patients were treated with a quadruple regimen. Resistance to isoniazid was documented in two patients from Latin America.

    2012-01-01

    Background: Although persistent trigeminal artery (PTA) is uncommonly identified, knowledge of this structure is essential for clinicians who interpret cranial imaging, perform invasive studies of the cerebral vasculature, and operate this region. Methods: A review of the medical literature using standard search engines was performed to locate articles regarding the PTA, with special attention with anatomical descriptions. Results: Although anatomical reports of PTA anatomy are very scarce, those were analyzed to describe in detail the current knowledge about its anatomical relationships and variants. Additionally, the embryology, classification, clinical implications, and imaging modalities of this vessel are extensively discussed. Conclusions: Through a comprehensive review of isolated reports of the PTA, the clinician can better understand and treat patients with such an anatomical derailment. PMID:23087827

    Calibre persistent labial artery (CPLA) usually presents as an asymptomatic papule on the lower lip and can be easily misdiagnosed as a mucocele, haemangioma, venous lake, varix or fibroma. When it is ulcerated, squamous cell carcinoma is the most usual differential diagnosis. Here, we report a case of a 25-year-old woman with no previous relevant medical history who presented with a complaint of an asymptomatic, non-ulcerated, progressively growing nodule (over the last 5 months) on the upper lip. In this case, the diagnosis was made clinically and confirmed by immunohistochemical analysis. We conclude that clinicians should be aware of CPLA and it should be included in the differential diagnosis of labial mucosal papules. Sometimes, the immunohistochemical analysis is necessary to make a correct diagnosis. PMID:26225087

    Calibre persistent labial artery (CPLA) is defined as a primary arterial branch that penetrates into the submucosal tissue without division or decrease in diameter. It usually presents as an asymptomatic papule on the lower lip and can be easily misdiagnosed as a varix, haemangioma, venous lake, mucocele or fibroma. When it is ulcerated, squamous cell carcinoma is the most usual differential diagnosis. The most frequently used method to confirm the diagnosis of CPLA has been excisional biopsy, which carries the risk of profuse bleeding. Angiography, another invasive method, has also been used. Here, we report a case of a 20-year-old woman with a 5-year history of multiple CPLA lesions involving both upper and lower lips. In this case, the diagnosis was made clinically and confirmed by Doppler ultrasonography, which is a noninvasive and simple diagnostic tool. PMID:16716155

    A 2-year-old male, intact Yorkshire terrier presented with a 1-month history of progressive paraparesis. Neurological examination revealed paraplegia with absent deep pain perception, decreased right pelvic limb withdrawal reflex, and lumbar pain consistent with an L4-S2 neurolocalization. Magnetic resonance imaging (MRI) showed a single, well-demarcated, intramedullary mass centered over the L3-4 disk space. A hemilaminectomy was performed, and the mass was removed en bloc. Histopathological evaluation was consistent with a hemangioblastoma. Follow-up MRI 9 months after surgery showed no evidence of tumor recurrence, and the dog was ambulatory paraparetic at that time. This case is consistent with a previous histopathological report of spinal cord hemangioblastoma in a dog and provides additional clinical information regarding diagnosis, treatment, and outcome associated with this tumor type.

    A 2-year-old male, intact Yorkshire terrier presented with a 1-month history of progressive paraparesis. Neurological examination revealed paraplegia with absent deep pain perception, decreased right pelvic limb withdrawal reflex, and lumbar pain consistent with an L4–S2 neurolocalization. Magnetic resonance imaging (MRI) showed a single, well-demarcated, intramedullary mass centered over the L3–4 disk space. A hemilaminectomy was performed, and the mass was removed en bloc. Histopathological evaluation was consistent with a hemangioblastoma. Follow-up MRI 9 months after surgery showed no evidence of tumor recurrence, and the dog was ambulatory paraparetic at that time.

    A retrospective study was conducted of the clinical records of 41 patients discharged from a hospital in Tarapoto, Peru, between August 1992 and June 1996 following treatment for Plasmodium falciparum malaria. Patients ranged in age from 18 to 65 years; 25 were male. The cases were uniformly distributed throughout the year. The duration of illness averaged 11 days. At admission, 40 patients had fever, 36 had shaking chills, 29 had headache, 21 had nausea and vomiting, 21 had hyporexia, 15 had pallor, and 13 had splenomegaly. 3 of the 16 women were pregnant. 7 patients reported a history of malaria. The admission diagnosis was malaria in 33 cases. 31 patients were treated with chloroquine; 18 were subsequently treated with pyrimethamine-sulfadoxin and 1 received doxycycline. No cases of grave illness or death occurred. The increasing presence of Plasmodium falciparum malaria in the Peruvian lowlands should promote review of the adequacy of control programs.

    Diseases of the lung are one of the main causes of morbidity and mortality in the elderly. The risk of respiratory infections is increased due to structural changes, malnutrition, co-morbidity, and a variety of other factors. Bacterial and viral pathogens cause acute bronchitis and exacerbations of chronic bronchitis (AECB). Community acquired pneumonias (CAP) show a different spectrum of pathogens and clinical course in comparison to nosocomial pneumonias (hospital acquired pneumonia, HAP). Institutionalised patients are at risk of a health care associated pneumonia (HCAP), with often a different spectrum of pathogens in comparison to CAP and HAP. Elderly patients with cerebrovascular disease and impairment of swallowing or cough reflexes often suffer from aspiration pneumonias. The mortality is highest in the elderly, comorbid, and immunocompromised patient with nosocomial pneumonia. Important preventive measures include influenza and pneumococcal vaccination, avoidance of immobility, oral hygiene, and sufficient nutrition.

    Scrub typhus infection is an important cause of acute undifferentiated fever in South East Asia. The clinical picture is characterized by sudden onset fever with chills and non-specific symptoms that include headache, myalgia, sweating and vomiting. The presence of an eschar, in about half the patients with proven scrub typhus infection and usually seen in the axilla, groin or inguinal region, is characteristic of scrub typhus. Common laboratory findings are elevated liver transaminases, thrombocytopenia and leukocytosis. About a third of patients admitted to hospital with scrub typhus infection have evidence of organ dysfunction that may include respiratory failure, circulatory shock, mild renal or hepatic dysfunction, central nervous system involvement or hematological abnormalities. Since the symptoms and signs are non-specific and resemble other tropical infections like malaria, enteric fever, dengue or leptospirosis, appropriate laboratory tests are necessary to confirm diagnosis. Serological assays are the mainstay of diagnosis as they are easy to perform; the reference test is the indirect immunofluorescence assay (IFA) for the detection of IgM antibodies. However in clinical practice, the enzyme-linked immuno-sorbent assay is done due to the ease of performing this test and a good sensitivity and sensitivity when compared with the IFA. Paired samples, obtained at least two weeks apart, demonstrating a ≥ 4 fold rise in titre, is necessary for confirmation of serologic diagnosis. The mainstay of treatment is the tetracycline group of antibiotics or chloramphenicol although macrolides are used alternatively. In mild cases, recovery is complete. In severe cases with multi-organ failure, mortality may be as high as 24%. PMID:26261776

    Toxoplasmosis is caused by a coccidian parasite, Toxoplasma gondii. The parasite is highly prevalent both in humans and in warm-blooded animals. Cat family animals are definitive host, and these animals excrete the infective oocysts in their feces. Humans, though not definitive host, get infection by consuming water or food contaminated with cat feces. Rarely, infection can also take place through transfusing the infected blood, through transplantation of infected organs, or transplacentally from infected mother to fetus. Transplacental infection can cause congenital infection with varied degree of clinical manifestations, which depend on the age of fetus when infection took place. Diagnosis of congenital toxoplasmosis is difficult to establish until it is suspected and laboratory investigations are carried out. In more than 75% of cases, acute infection is missed due to very mild or unnoticeable clinical symptoms and signs. In India, a prevalence rate of 22.4% (8.8-37.3%) has been reported with an overall IgM positivity of 1.43%. It is estimated that approximately between 56,737 and 176,882 children per year are born in India with a possible risk of congenital toxoplasmosis. The diagnosis of congenital toxoplasmosis can be made by serological methods which are most commonly used. The other methods are parasite isolation by culture and molecular methods. Toxoplasmosis is treatable and transplacental transmission can be prevented by spiramycin, which concentrates in the placenta. However, if infection has done any damage to the fetus or the parasite has passed the placenta, spiramycin cannot reverse the damage. Prevention remains the best remedy. PMID:27722099

    Abstract Objective In light of the current controversy about whether severe temper outbursts are diagnostic of mania in young children, we conducted a study to characterize such children, focusing on mania and other mood disorders, emotion regulation, and parental psychiatric history. Methods Study participants included 51 5–9-year-old children with frequent, impairing outbursts (probands) and 24 non-referred controls without outbursts. Parents completed a lifetime clinical interview about their child, and rated their child's current mood and behavior. Teachers completed a behavior rating scale. To assess emotion regulation, children were administered the Balloons Game, which assesses emotion expressivity in response to frustration, under demands of high and low regulation. Parental lifetime diagnoses were ascertained in blind clinical interviews. Results No child had bipolar disorder, bipolar disorder not otherwise specified (NOS), or major depression (MDD). The most prevalent disorder was oppositional defiant disorder (88.2%), followed by attention-deficit/hyperactivity disorder (74.5%), anxiety disorders (49.0%), and non-MDD depressive disorders (33.3%). Eleven probands (21.6%) met criteria for severe mood dysregulation. During the Balloons Game, when there were no demands for self-regulation, children with severe outbursts showed reduced positive expressivity, and also showed significant deficits in controlling negative facial expressions when asked to do so. Anxiety disorders were the only diagnoses significantly elevated in probands' mothers. Conclusions Overall, young children with severe temper outbursts do not present with bipolar disorder. Rather, disruptive behavior disorders with anxiety and depressive mood are common. In children with severe outbursts, deficits in regulating emotional facial expressions may reflect deficits controlling negative affect. This work represents a first step towards elucidating mechanisms underlying severe outbursts in

    Background Plasmodium knowlesi is increasingly recognized as a cause of human malaria in Southeast Asia but there are no detailed prospective clinical studies of naturally acquired infections. Methods In a systematic study of the presentation and course of patients with acute P. knowlesi infection, clinical and laboratory data were collected from previously untreated, nonpregnant adults admitted to the hospital with polymerase chain reaction–confirmed acute malaria at Kapit Hospital (Sarawak, Malaysia) from July 2006 through February 2008. Results Of 152 patients recruited, 107 (70%) had P. knowlesi infection, 24 (16%) had Plasmodium falciparum infection, and 21 (14%) had Plasmodium vivax. Patients with P. knowlesi infection presented with a nonspecific febrile illness, had a baseline median parasitemia value at hospital admission of 1387 parasites/μL (interquartile range, 6–222,570 parasites/μL), and all were thrombocytopenic at hospital admission or on the following day. Most (93.5%) of the patients with P. knowlesi infection had uncomplicated malaria that responded to chloroquine and primaquine treatment. Based on World Health Organization criteria for falciparum malaria, 7 patients with P. knowlesi infection (6.5%) had severe infections at hospital admission. The most frequent complication was respiratory distress, which was present at hospital admission in 4 patients and developed after admission in an additional 3 patients. P. knowlesi parasitemia at hospital admission was an independent determinant of respiratory distress, as were serum creatinine level, serum bilirubin, and platelet count at admission (P < .002 for each). Two patients with knowlesi malaria died, representing a case fatality rate of 1.8% (95% confidence interval, 0.2%–6.6%). Conclusions Knowlesi malaria causes a wide spectrum of disease. Most cases are uncomplicated and respond promptly to treatment, but approximately 1 in 10 patients develop potentially fatal complications. PMID

    Tetanus is a CNS disorder characterized by muscle spasms that is caused by the exotoxin of an anaerobic bacterium, Clostridium tetani. This disease is killing tens of thousands of neonates in developing countries. Although the incidence and mortality of tetanus has dramatically dropped in developed countries due to effective vaccination, appropriate wound management, and recent advances in intensive care, treatments remain difficult. From among developed countries, Japan has had a relatively high incidence of tetanus, and prevention is the problem especially in the elderly. We analyzed the data from 12 patients admitted to our hospital during 1997-2010. Their age ranged from 50-82 years; median 72 years with male to female ratio 5: 7, and all patients lacked a reliable history of toxoid immunization. Five patients out of 12 had history of cancer and one each had diabetes mellitus, pulmonary emphysema and Sjogren syndrome. In some cases, the patients had been initially misdiagnosed with ENT disorders, dental problems, or psychosis. Therefore to date, observation of clinical symptoms such as difficulty in mouth opening is considered the most crucial for diagnosis. The shorter was a period from onset to generalized convulsion (onset time), the longer was a duration of hospital stay. A notable complication was intramuscular hemorrhage in the lumbar muscles, which occurred in 2 patients. No patients died due to ICU managements, in which the most useful were propofol for spasm control and sedation, and magnesium sulfate for autonomic overactivity. Retrospectively, the Tetanus Severity Score (TSS) for mortality proposed by Thwaites et al (2006) is considered a useful tool also for predicting the clinical outcome at discharge. Although tetanus has been traditionally classified into the generalized, local, and cephalic types, a simpler severity-based classification into "severe", "moderate", and "mild" types may be more practical with regard to disease management.

  17. Recognizing clinical entities in hospital discharge summaries using Structural Support Vector Machines with word representation features

    2013-01-01

    Background Named entity recognition (NER) is an important task in clinical natural language processing (NLP) research. Machine learning (ML) based NER methods have shown good performance in recognizing entities in clinical text. Algorithms and features are two important factors that largely affect the performance of ML-based NER systems. Conditional Random Fields (CRFs), a sequential labelling algorithm, and Support Vector Machines (SVMs), which is based on large margin theory, are two typical machine learning algorithms that have been widely applied to clinical NER tasks. For features, syntactic and semantic information of context words has often been used in clinical NER systems. However, Structural Support Vector Machines (SSVMs), an algorithm that combines the advantages of both CRFs and SVMs, and word representation features, which contain word-level back-off information over large unlabelled corpus by unsupervised algorithms, have not been extensively investigated for clinical text processing. Therefore, the primary goal of this study is to evaluate the use of SSVMs and word representation features in clinical NER tasks. Methods In this study, we developed SSVMs-based NER systems to recognize clinical entities in hospital discharge summaries, using the data set from the concept extration task in the 2010 i2b2 NLP challenge. We compared the performance of CRFs and SSVMs-based NER classifiers with the same feature sets. Furthermore, we extracted two different types of word representation features (clustering-based representation features and distributional representation features) and integrated them with the SSVMs-based clinical NER system. We then reported the performance of SSVM-based NER systems with different types of word representation features. Results and discussion Using the same training (N = 27,837) and test (N = 45,009) sets in the challenge, our evaluation showed that the SSVMs-based NER systems achieved better performance than the CRFs

    The objective was to describe in multiple sclerosis, a cerebellar eye movement syndrome that resulted from an acute episode of inflammatory demyelination. Contrapulsion is an ocular motor disturbance characterised by a triad of (1) hypermetric saccadic eye movements in a direction opposite from a precisely localised lesion within a specific white matter pathway, the uncinate fasciculus, at the level of the superior cerebellar peduncle (SCP); (2) hypometric saccades towards the side of the lesion; (3) oblique saccades directed away from the side of the lesion on attempted vertical saccades.
 Infrared oculography was used to demonstrate the characteristic features of contrapulsion in two patients with multiple sclerosis.
 Brain MRI showed lesions within the region of the uncinate fasciculus and superior cerebellar peduncle in both patients. Eye movement recordings showed saccadic hypermetria away from the side of the lesion and saccadic hypometria towards the side of the lesion. The hypometria decomposed into a series of stepwise movements as the eye approached the target. Oblique saccades directed away from the side of the lesion were seen on attempted vertical saccades.
In conclusion, ocular contrapulsion can be seen in patients with multiple sclerosis and results from a lesion in the region of the SCP, involving the uncinate fasciculus.

    Acute inflammatory lesions of the placenta consist of diffuse infiltration of neutrophils at different sites in the organ. These lesions include acute chorioamnionitis, funisitis, and chorionic vasculitis, and represent a host response (maternal or fetal) to a chemotactic gradient in the amniotic cavity. While acute chorioamnionitis is evidence of a maternal host response, funisitis and chorionic vasculitis represent fetal inflammatory responses. Intra-amniotic infection has been generally considered to be the cause of acute histologic chorioamnionitis and funisitis; however, recent evidence indicates that “sterile” intra-amniotic inflammation, which occurs in the absence of demonstrable microorganisms but can be induced by “danger signals”, is frequently associated with these lesions. In the context of intra-amniotic infection, chemokines (such as interleukin-8 and granulocyte chemotactic protein) establish a gradient favoring the migration of neutrophils from maternal or fetal circulation into the chorioamniotic membranes or umbilical cord, respectively. Danger signals released during the course of cellular stress or cell death can also induce the release of neutrophil chemokines. The prevalence of chorioamnionitis is a function of gestational age at birth, and is present in 3-5% of placentas delivered at term, but in 94% of placentas delivered between 21-24 weeks of gestation. The frequency is higher in patients with spontaneous labor, preterm labor, clinical chorioamnionitis (preterm or term), or ruptured membranes. Funisitis and chorionic vasculitis are the hallmarks for the fetal inflammatory response syndrome, a condition characterized by an elevation in fetal plasma concentrations of interleukin-6, associated with the impending onset of preterm labor, a higher rate of neonatal morbidity (after adjustment for gestational age), and multi-organ fetal involvement. This syndrome is the counterpart of the systemic inflammatory response syndrome in adults

    Enteropathy-associated T-cell lymphomas (EATL) are rare and generally aggressive types of peripheral T-cell lymphomas. Rare cases of primary, small intestinal CD4+ T-cell lymphomas with indolent behavior have been described, but are not well characterized. We describe morphologic, phenotypic, genomic and clinical features of 3 cases of indolent primary small intestinal CD4+ T-cell lymphomas. All patients presented with diarrhea and weight loss and were diagnosed with celiac disease refractory to a gluten free diet at referring institutions. Small intestinal biopsies showed crypt hyperplasia, villous atrophy and a dense lamina propria infiltrate of small-sized CD4+ T-cells often with CD7 downregulation or loss. Gastric and colonic involvement was also detected (n = 2 each). Persistent, clonal TCRβ gene rearrangement products were detected at multiple sites. SNP array analysis showed relative genomic stability, early in disease course, and non-recurrent genetic abnormalities, but complex changes were seen at disease transformation (n = 1). Two patients are alive with persistent disease (4.6 and 2.5 years post-diagnosis), despite immunomodulatory therapy; one died due to bowel perforation related to large cell transformation 11 years post-diagnosis. Unique pathobiologic features warrant designation of indolent small intestinal CD4+ T-cell lymphoma as a distinct entity, greater awareness of which would avoid misdiagnosis as EATL or an inflammatory disorder, especially celiac disease.

    This retrospective study investigated the clinical characteristics and antimicrobial susceptibilities of 36 cases of Citrobacter freundii bacteremia treated at the Taipei Veterans General Hospital from 1996 through 1999. The results showed that the predominant infection site was the intraabdominal region and the mortality was 22%. The resistance of C. freundii to most third-generation cephalosporins and broad-spectrum penicillins increased in both nosocomial and community-acquired C. freundii bacteremia during the study period, and the strategy of using a combination of antimicrobial agents to treat C. freundii infection was effective. This study also demonstrated the importance of appropriate antimicrobial therapy to the successful outcome of C. freundii bacteremia. The guidelines of the National Nosocomial Infections Surveillance System were followed to determine trends of resistance of C. freundii to various antimicrobial agents. The resistance of C. freundii to antibiotics in 1999 (n = 10), compared with the period from 1996 through 1998 (n = 26), increased 66% for ciprofloxacin, 36% for ticarcillin/clavulanate, 70% for piperacillin/tazobactam, and 62.8% for piperacillin, but remained uniformly susceptible to imipenem/cilastatin and the new fluoroquinolone (levofloxacin). This increase in resistance was attributable to the use of third-generation cephalosporin instead of first-generation cephalosporins. These findings indicate the need for new measures to facilitate the appropriate choice of antimicrobial agents for patients with C. freundii bacteremia.

    Oxaliplatin, a third generation novel platinum compound is the most effective first line chemotherapeutic agent for colorectal cancer (CRC) in combination with 5FU and leucovorin. It is indicated for pancreatic, gastric and testicular cancers combined with bevacuzimab, capecitabine, irinotecan and other cytotoxic agents. However, moderate to severe hypersensitivity reactions (HSR) during or after oxaliplatin infusion usually require cessation of chemotherapy or substitution of the key therapeutic drug which largely interferes with improved patient prognosis. This mini- review showcases recent and accepted opinions/approaches in oxaliplatin induced HSR management. Physicians and oncologists have varying attitudes regarding the decision to rechallenge the patient after an HSR experience, efficacy of desensitization protocols, effectiveness and selection of drugs for premedication and possibilities of cross sensitivity to other platinum agents (e.g. carboplatin). A brief insight into underlying molecular mechanisms and clinical manifestations of oxaliplatin induced HSR is offered. We have also discussed the management of oxaliplatin induced HSR and risk stratification for a successful and complete chemotherapeutic plan. PMID:27221832

    Vasculitic peripheral neuropathy (VPN) occurs due to ischemic changes of peripheral nerves, resulting from a deficit of vascular blood supply due to damaged vasa nervorum leading to vasculitis. VPN usually manifests as sensorimotor or sensory disturbances accompanied by pain, presenting as a type of multiple mononeuropathy, with a scattered distribution in distal limbs. VPN may also present as a mononeuropathy, distal symmetric polyneuropathy, plexopathy, or radiculopathy. The rapidity of VPN is variable, ranging from days to months, with symptoms occasionally changing with the appearance of new lesions. Careful history taking and neurological examination provides an exact diagnosis. The most common cause of VPN is primary vasculitis predominantly affecting small vessels, including vasa nervorum, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, and polyarteritis nodosa. Similar vasculitic processes can also result from a systemic collagen disorder or secondary vasculitis. Electrophysiological studies and pathological investigation of biopsied peripheral nerves and muscles are important for diagnosis of vasculitis. Serological tests, including ANCA, are useful for diagnosis of vasculitis. Accurate neurological examinations are essential for diagnosis and evaluation of clinical course.

    This report describes a suicide case by acute arsenic intoxication via intravenous injection. A 30-year-old woman injected arsenic As (V) (sodium arseniate disodique: Disodium Hydrogena Arsenik RP) in a successful suicide attempt. Three hours following administration, the woman developed severe digestive symptoms. She was admitted to a hospital and transferred to the intensive care unit within 12 h of the massive administration of arsenic. Despite therapeutic efforts, over the next 2 h she developed multiorgan failure and died. A postmortem examination was performed. Pulmonary edema and congestion of liver were apparent. As (V) and As (III) were determined by high performance liquid chromatography and inductively coupled plasma mass spectrometry after mineralization of samples by concentrated nitric acid. Toxicological analysis revealed high concentrations of arsenic in biological fluids as well as in organs. Histopathological examination showed a typical indication of myocarditis. These findings were in agreement with acute arsenic poisoning. The symptoms developed by this young woman (intoxication by intravenous administration) were comparable to oral intoxication. The clinical signs, survival time, and administration type are discussed in light of the literature on acute and chronic arsenic poisoning.

    Oxaliplatin, a third generation novel platinum compound is the most effective first line chemotherapeutic agent for colorectal cancer (CRC) in combination with 5FU and leucovorin. It is indicated for pancreatic, gastric and testicular cancers combined with bevacuzimab, capecitabine, irinotecan and other cytotoxic agents. However, moderate to severe hypersensitivity reactions (HSR) during or after oxaliplatin infusion usually require cessation of chemotherapy or substitution of the key therapeutic drug which largely interferes with improved patient prognosis. This mini- review showcases recent and accepted opinions/approaches in oxaliplatin induced HSR management. Physicians and oncologists have varying attitudes regarding the decision to rechallenge the patient after an HSR experience, efficacy of desensitization protocols, effectiveness and selection of drugs for premedication and possibilities of cross sensitivity to other platinum agents (e.g. carboplatin). A brief insight into underlying molecular mechanisms and clinical manifestations of oxaliplatin induced HSR is offered. We have also discussed the management of oxaliplatin induced HSR and risk stratification for a successful and complete chemotherapeutic plan.

  8. [Vasculitic Peripheral Neuropathies: Clinical Features and Diagnostic Laboratory Tests].

    Vasculitic peripheral neuropathy (VPN) occurs due to ischemic changes of peripheral nerves, resulting from a deficit of vascular blood supply due to damaged vasa nervorum leading to vasculitis. VPN usually manifests as sensorimotor or sensory disturbances accompanied by pain, presenting as a type of multiple mononeuropathy, with a scattered distribution in distal limbs. VPN may also present as a mononeuropathy, distal symmetric polyneuropathy, plexopathy, or radiculopathy. The rapidity of VPN is variable, ranging from days to months, with symptoms occasionally changing with the appearance of new lesions. Careful history taking and neurological examination provides an exact diagnosis. The most common cause of VPN is primary vasculitis predominantly affecting small vessels, including vasa nervorum, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, and polyarteritis nodosa. Similar vasculitic processes can also result from a systemic collagen disorder or secondary vasculitis. Electrophysiological studies and pathological investigation of biopsied peripheral nerves and muscles are important for diagnosis of vasculitis. Serological tests, including ANCA, are useful for diagnosis of vasculitis. Accurate neurological examinations are essential for diagnosis and evaluation of clinical course. PMID:27001769

  9. Alternaria infections: laboratory diagnosis and relevant clinical features.

    The genus Alternaria contains several species of melanized hyphomycetes that cause opportunistic human infections. The published literature contains 210 reported cases of human alternarioses between 1933 and the present day. The most frequent clinical manifestations are cutaneous and subcutaneous infections (74.3%), followed by oculomycosis (9.5%), invasive and non-invasive rhinosinusitis (8.1%) and onychomycosis (8.1%). Immunosuppression is frequently associated with cutaneous and subcutaneous infections and rhinosinusitis. The most important risk factors for cutaneous and subcutaneous infections are solid organ transplantation and Cushing's syndrome, and those for rhinosinusitis are bone marrow transplants. Having been exposed to soil and garbage is common in all cases of oculomycosis, with corticotherapy being a risk factor in 50% of these cases. Previous contact with soil and/or trauma to the nails is associated with most cases of onychomycosis. In general, alternariosis shows a good response to conventional antifungal drugs. On some occasions, steroid suppression or reduction is sufficient to resolve an infection. Itraconazole is the antifungal drug used most frequently to successfully treat onychomycosis and cutaneous and subcutaneous infections. Posaconazole and voriconazole are promising therapeutic options, with the latter being especially so for oculomycosis.

    Nemaline myopathy (NEM) is one of the most common congenital myopathies. A unique subtype, NEM6, maps to chromosome 15q21-q23 in two pedigrees, but the causative gene has not been determined. We conducted clinical examination and myopathological studies in a new NEM family. Genotyping and gene screening were accomplished by searching known and 18 new candidate genes. The disease started in childhood by affecting proximal and distal muscles and causing slowness of movements. Muscle biopsies showed numerous nemaline rods and core-like formations. Suggestive linkage to chromosome 15q22-q23 was established. Genes known to be mutated in NEM or core-rod myopathy were screened and excluded. No pathogenic mutations were identified in other candidate genes. The disease in this Spanish family was classified as NEM6. It is phenotypically similar and probably allelic to the two previously reported NEM6 pedigrees. Further studies of these families will lead to the identification of the NEM6 gene. PMID:21104864

    The term, ocular toxoplasmosis, refers to eye disease related to infection with the parasite, Toxoplasma gondii. Recurrent posterior uveitis is the typical form of this disease, characterized by unilateral, necrotizing retinitis with secondary choroiditis, occurring adjacent to a pigmented retinochoroidal scar and associated with retinal vasculitis and vitritis. Multiple atypical presentations are also described, and severe inflammation is observed in immunocompromised patients. Histopathological correlations demonstrate focal coagulative retinal necrosis, and early in the course of the disease, this inflammation is based in the inner retina. For typical ocular toxoplasmosis, a diagnosis is easily made on clinical examination. In atypical cases, ocular fluid testing to detect parasite DNA by polymerase chain reaction or to determine intraocular production of specific antibody may be extremely helpful for establishing aetiology. Given the high seroprevalence of toxoplasmosis in most communities, serological testing for T. gondii antibodies is generally not useful. Despite a lack of published evidence for effectiveness of current therapies, most ophthalmologists elect to treat patients with ocular toxoplasmosis that reduces or threatens to impact vision. Classic therapy consists of oral pyrimethamine and sulfadiazine, plus systemic corticosteroid. Substantial toxicity of this drug combination has spurred interest in alternative antimicrobials, as well as local forms of drug delivery. At this time, however, no therapeutic approach is curative of ocular toxoplasmosis. PMID:22712598

    Background: Alopecia can be a manifestation of mycosis fungoides (MF); however, the prevalence is unknown. Aims: We sought to describe the clinicopathologic presentation of alopecia in patients with diagnosis of MF. Methods: A retrospective analysis of patients with biopsy-proven MF, who were evaluated at our cancer center from 2002 to 2012, was performed to identify patients with alopecia. Results: Five patients with alopecia were identified from reviewing of 157 patients with MF. The male:female ratio was 3:2, and the mean age of patients was 42.8 years. Two of these patients showed patchy hair loss on scalp which was clinically identical to alopecia areata. In remaining three patients, hair loss was seen in areas of MF lesions, and epidermal changes consisted of patch- and plaque-type lesions of MF, tumors, and follicular lesions (follicular MF) were also present. In two of these patients, lymphadenopathy without any visceral involvement was detected. Conclusions: Alopecia was observed in 5 (3.18%) patients with MF, which makes it a rare finding, which included alopecia areata-like patchy loss in 2 and alopecia within MF lesions in 3.

    Abstract Hirayama disease (HD) is characterized by development of asymmetric forearm muscle atrophy during adolescence with or without focal cervical spinal cord atrophy. The purpose of this study is to assess the correlation of clinical symptoms, disease progression, and electrophysiological findings with cervical spine magnetic resonance imaging (MRI) findings. The medical records, cervical spine MRIs, and electrophysiological findings of 44 HD patients were retrospectively reviewed and analyzed. Denervation changes in any single C5 to C7 root-innervated muscle (deltoid, biceps, triceps, or extensor digitorum communis) occurred more frequently in the 25 patients with cord atrophy than the 19 patients without cord atrophy (88% vs 53%, P = 0.02). Onset age, duration of disease progression, neurological examinations, nerve conduction study, and electromyographic findings from individual muscles were similar between patient groups. Compared with HD patients without cord atrophy, HD patients with cord atrophy experience a more severe denervation change in C5 to C7 root-innervated muscles. PMID:27428223

    Nineteen adults with brain tumors have been studied with positron emission tomography utilizing FDG. Fourteen had biopsy proven cerebral malignant glioma, one each had meningioma, hemangiopericytoma, primitive neuroectodermal tumor (PNET), two had unbiopsied lesions, and one patient had an area of biopsy proven radiation necrosis. Three different patterns of glucose metabolism are observed: marked increase in metabolism at the site of the known tumor in (10 high grade gliomas and the PNET), lower than normal metabolism at the tumor (in 1 grade II glioma, 3 grade III gliomas, 2 unbiopsied low density nonenhancing lesions, and the meningioma), no abnormality (1 enhancing glioma, the hemangiopericytoma and the radiation necrosis.) The metabolic rate of the tumor or the surrounding brain did not appear to be correlated with the history of previous irradiation or chemotherapy. Decreased metabolism was frequently observed in the rest of the affected hemisphere and in the contralateral cerebellum. Tumors of high grade or with enhancing CT characteristics were more likely to show increased metabolism. Among the patients with proven gliomas, survival after PETT scan tended to be longer for those with low metabolic activity tumors than for those with highly active tumors. The authors conclude that PETT may help to predict the malignant potential of tumors, and may add useful clinical information to the CT scan.

    The clinical picture of candidal vaginitis was described for the first time in 1792. The connection with yeasts was already discovered in the 19th century. Not until the last 35 years, however, have the epidemiologic aspects of genital mycoses and the diagnostic and therapeutic principles been systematically developed. The rise in the incidence of the disease is due to several factors: the administration of corticosteroids, cystostatic agents, and oral contraceptives as well as socioeconomic circumstances. Two serious complications of vaginal yeast infection in pregnant women should be noted: the amniotic infection syndrome and neonatal contamination at the time of delivery. Vulvovaginitis is one of the most common genital diseases in childhood and adolescence. Mycoses can be diagnosed in daily gynecological practice by simple, reliable methods, but only culture on prepared media or by incubation of standardized plates can be depended upon to establish or rule out a mycosis. Effective antimycotics with a broad spectrum of activity have been developed in the last 15 years. We have been primarily concerned with clotrimazole because of our own investigations and impartial comparisons with other fungicidal drugs. Studies of patient compliance have shown that the diseased women accept short-term therapy most readily. However, appropriate control examinations are needed to document the results of treatment.

    Acute acquired concomitant esotropia (AACE) is a rare, distinct subtype of esotropia. The purpose of this retrospective study was to describe the clinical characteristics and discuss the classification and etiology of AACE.Charts from 47 patients with AACE referred to our institute between October 2010 and November 2014 were reviewed. All participants underwent a complete medical history, ophthalmologic and orthoptic examinations, and brain and orbital imaging.Mean age at onset was 26.6 ± 12.2 years. Of the 18 cases with deviations ≤ 20 PD, 16 presented with diplopia at distance and fusion at near vision at the onset of deviation; differences between distance and near deviations were < 8 PD; all cases except one were treated with prism and diplopia resolved. Of the 29 cases with deviations > 20 PD, 5 were mild hypermetropic with age at onset between 5 and 19 years, 16 were myopic, and 8 were emmetropic with age at onset > 12 years; 24 were surgically treated and 5 cases remained under observation; all 24 cases achieved normal retinal correspondence or fusion or stereopsis on postoperative day 1 in synoptophore; in 23 cases diplopia or visual confusion resolved postoperatively. Of the 47 cases, brain and orbital imaging in 2 cases revealed a tumor in the cerebellopontine angle and 1 case involved spinocerebellar ataxia as revealed by genetic testing.AACE in this study was characterized by a sudden onset of concomitant nonaccommodative esotropia with diplopia or visual confusion at 5 years of age or older and the potential for normal binocular vision. We suggest that AACE can be divided into 2 subgroups consisting of patients with relatively small versus large angle deviations. Coexisting or underlying neurological diseases were infrequent in AACE. PMID:26705210

    Seizures are observed with a frequency of 3-21% in children with fetal alcohol spectrum disorders (FASD). However, clinical, neuroradiologic, and electroencephalography (EEG) features are poorly described. In this study, 13 patients with FASD and epilepsy or seizures were identified retrospectively from the databases of seven Italian pediatric neurology divisions. Eleven children were affected by epilepsy, and two had at least one documented seizure. Both generalized and focal seizures were observed. EEG showed diffuse or focal epileptic activity; two children developed electric status epilepticus during sleep (ESES). Structural brain anomalies, including polymicrogyria, nodular heterotopia, atrophy, and Arnold-Chiari type 1 malformation, were discovered in almost 50% of patients. Control of seizures was not difficult to obtain in 11 cases; one patient showed pharmacoresistant epilepsy. EEG and clinical follow-up are recommended in children with FASD and epilepsy, since severe conditions requiring aggressive treatment, such as in ESES, may develop. Neuroradiological evaluation is warranted because several types of brain anomalies could be associated with maternal alcohol consumption during pregnancy.

    Aggressive fibromatosis is a comparitively rare tumor with unpredictable growth and varying local recurrence rates. It does not develop distant metastases but locally it shows an aggressive and infiltrative behavior. Clinically, aggressive fibromatosis manifests as a painless, firm, often rapidly enlarging mass, fixed to underlying bone or soft tissue. It is never encapsulated. Histologically, it is rich in collagen and fibroblastic cells that are devoid of hyperchromatic or atypical nuclei, but with more variable cellularity in different tumor sections. PMID:21731285

    The clinical significance of concurrent expression of MYC and BCL2 protein, known as "double-expressor lymphoma" (DEL), among patients with relapsed or refractory aggressive B-cell lymphomas, remains unclear. A retrospective analysis was performed of 38 patients treated with a salvage treatment consisting of rituximab, ifosfamide, etoposide, cytarabine and dexamethasone followed by consolidative high-dose chemotherapies. A total of 17 cases (45%) were categorized as DEL using immunohistochemical assay with a cut-off value of positivity of 40% for MYC and 50% for BCL2, respectively. DEL was associated with a lower overall response rate (35% vs 71%, p = 0.0481), worse 2-year progression-free survival (9% vs 67%, p = 0.001) and overall survival (35% vs 71%, p = 0.037). This analysis suggests that DEL is common among patients with relapsed/refractory aggressive B-cell lymphomas and that such patients require novel treatment strategies.

    This article synthesizes theoretical material from psychology research into a practical model for conceptualizing violence in psychiatric settings. Relevant research and theory are reviewed, focusing on two important behavioral models of aggressive behavior, hostile aggression and instrumental aggression. The concepts of reinforcement, anticipated rewards, specific and nonspecific stimulus-driven aggression, intermediary emotional states in aroused persons, and the aggression stimulus threshold are developed into a bimodal model applicable to the clinical management of violence. The model provides a broad framework for categorizing, understanding, and addressing aggressive behavior in clinical settings.

    We present an approach for the analysis of clinical data from extremely preterm infants, in order to determine if they are ready to be removed from invasive endotracheal mechanical ventilation. The data includes over 100 clinical features, and the subject population is naturally quite small. To address this problem, we use feature selection, specifically mutual information, in order to choose a small subset of informative features. The other challenge we address is class imbalance, as there are many more babies that succeed extubation than those who fail. To handle this problem, we use SMOTE, an algorithm which creates synthetic examples of the minority class.

    The t(4;14) translocation, found in 15% of multiple myeloma (MM), indicates a poor prognosis. Clinico-biological features associated with this severe outcome and the impact of novel agents are unknown. We report a series of 102 consecutive patients with t(4;14) MM. The median age was 56 years. The isotype was IgA in 42%, and the median serum β(2)-microglobulin was 2.3 mg/L. FGFR3 expression was lacking in 20 (19%) cases. Monoclonal gammopathy of undetermined significance (MGUS) or smoldering MM (sMM) was found in 26 patients (25%). Seven (27%) became symptomatic in a median time of 9 months. Fifty-six of 76 patients with symptomatic MM received high-dose therapy (HDT). The overall response rate (ORR) was 93% (22% CR, 44% VGPR), and the median progression-free survival (PFS) was 12 months. Twenty-four (37%) patients experienced aggressive relapse. Post-second-line ORR was 51% and the median PFS was 7 months, with a trend for longer PFS in patients treated with a bortezomib-based regimen. Median overall survival after HDT was 31 months. t(4;14) is detected in patients with MGUS/sMM and this does not require immediate chemotherapy. Patients with t(4;14) MM have a high ORR after HDT, contrasting with a short PFS and aggressive relapses, and, despite novel agents, still have a poor prognosis. PMID:21261498

    Patients with a clinical history of migraine were evaluated psychiatrically, and by electroencephalography. They were challenged with food antigens by skin-prick test, and abdominal symptoms were evaluated following oral ingestion of food allergens. A significant correlation was found between challenge with specific food allergens and the development of migraine headaches, the appearance of abdominal symptoms and the occurrence of positive skin reactions. Psychiatric abnormalities and EEG alterations were associated with the occurrence of headaches and allergic clinical features. It is suggested that the clinical features of migraine can be explained as a result of release of chemical mediators following antigen-antibody reactions in the brain and other tissues where specific antibodies are localized. The continuous ingestion of the responsible food allergens would account for the raised tissue concentrations of noradrenaline, histamine and other mediators to which the clinical features of migraine are attributed.

    Modern healthcare is getting reshaped by growing Electronic Medical Records (EMR). Recently, these records have been shown of great value towards building clinical prediction models. In EMR data, patients' diseases and hospital interventions are captured through a set of diagnoses and procedures codes. These codes are usually represented in a tree form (e.g. ICD-10 tree) and the codes within a tree branch may be highly correlated. These codes can be used as features to build a prediction model and an appropriate feature selection can inform a clinician about important risk factors for a disease. Traditional feature selection methods (e.g. Information Gain, T-test, etc.) consider each variable independently and usually end up having a long feature list. Recently, Lasso and related l1-penalty based feature selection methods have become popular due to their joint feature selection property. However, Lasso is known to have problems of selecting one feature of many correlated features randomly. This hinders the clinicians to arrive at a stable feature set, which is crucial for clinical decision making process. In this paper, we solve this problem by using a recently proposed Tree-Lasso model. Since, the stability behavior of Tree-Lasso is not well understood, we study the stability behavior of Tree-Lasso and compare it with other feature selection methods. Using a synthetic and two real-world datasets (Cancer and Acute Myocardial Infarction), we show that Tree-Lasso based feature selection is significantly more stable than Lasso and comparable to other methods e.g. Information Gain, ReliefF and T-test. We further show that, using different types of classifiers such as logistic regression, naive Bayes, support vector machines, decision trees and Random Forest, the classification performance of Tree-Lasso is comparable to Lasso and better than other methods. Our result has implications in identifying stable risk factors for many healthcare problems and therefore can

    Objectives Since lipid compounds are known to modulate the function of CD4+ T-cells and macrophages, we hypothesize that altered levels of serum non-esterified fatty acids (NEFA) may underlie rheumatoid arthritis (RA) pathogenesis. Methods Serum levels of NEFA (palmitic, stearic, palmitoleic, oleic, linoleic, γ-linoleic, arachidonic –AA–, linolenic, eicosapentaenoic –EPA– and docosahexaenoic –DHA–) were quantified by LC-MS/MS after methyl-tert-butylether (MTBE)-extraction in 124 RA patients and 56 healthy controls (HC). CD4+ phenotype was studied by flow cytometry. TNFα, IL-8, VEGF, GM-CSF, IFNγ, IL-17, CCL2, CXCL10, leptin and resistin serum levels were quantified by immunoassays. The effect of FA on IFNγ production by PBMC was evaluated in vitro. Results Lower levels of palmitic (p<0.0001), palmitoleic (p = 0.002), oleic (p = 0.010), arachidonic (p = 0.027), EPA (p<0.0001) and DHA (p<0.0001) were found in RA patients, some NEFA being altered at onset. Cluster analysis identified a NEFA profile (hallmarked by increased stearic and decreased EPA and DHA) overrepresented in RA patients compared to HC (p = 0.002), being associated with clinical features (RF, shared epitope and erosions), increased IFNγ expression in CD4+ T-cells (p = 0.002) and a Th1-enriched serum milieu (IFNγ, CCL2 and CXCL10, all p<0.005). In vitro assays demonstrated that imbalanced FA could underlie IFNγ production by CD4+ T-cells. Finally, changes on NEFA levels were associated with clinical response upon TNFα-blockade. Conclusion An altered NEFA profile can be found in RA patients associated with clinical characteristics of aggressive disease and enhanced Th1 response. These results support the relevance of lipidomic studies in RA and provide a rationale for new therapeutic targets. PMID:27487156

  15. Concurrent West Nile virus infection in pneumococcal meningitis: clinical and MRI features.

    We report the clinical and neuroimaging findings of an immunocompetent patient with concurrent pneumococcal and West Nile virus meningoencephalitis with relapsing clinical course despite a full course of antibiotic treatment. The patient developed acute oculomotor nerve palsy with pupillary involvement and bilateral hearing loss, and delayed right leg monoparesis. We speculate that coexisting bacterial and viral neuroinvasive infections contributed to the unusual clinical and imaging manifestations, and that overwhelming laboratory and clinical features of bacterial meningitis masked the typical features of CNS viral infection. Therefore, atypical presentations of bacterial meningitis should raise a high index of suspicion for coexisting infections, even in immunocompetent patients, and evolving neuroimaging findings may be helpful in substantiating clinical suspicion and guiding further management.

    Mycosis fungoides is the most common type of cutaneous T-cell lymphoma (CTCL) and a rare disorder that typically affects older adults with erythematous scaling patches and plaques. Hypopigmented patches are a rare clinical variant of the disease. Granulomatous mycosis fungoides (GMF) is also a rare type of CTCL. No particular clinical criteria are available for the diagnosis of GMF, because of its variable presentations, and so the detection of GMF is primarily considered as a histopathological diagnosis. Rarely, a co-existence of more than one clinical or histopathological feature of mycosis fungoides may be present. To the best of our knowledge this is the first report of MF that shows the simultaneous co-existence of more than one clinical and histopathological variant of MF. We present a 29-year-old female with clinical presentations of both classic and hypopigmented mycosis fungoides (MF), and also the histopathological features of the classic and granulomatous types of the disease.

    2012-01-01

    Parkinson’s disease (PD) is a common, disabling, neurodegenerative disorder. In addition to classical motor symptoms, non-motor features are now widely accepted as part of the clinical picture, and cognitive decline is a very important aspect of the disease, as it brings an additional significant burden for the patient and caregivers. The diagnosis of cognitive decline in PD, namely mild cognitive impairment (MCI) and dementia, can be extremely challenging, remaining largely based on clinical and cognitive assessments. Diagnostic criteria and methods for PD dementia and MCI have been recently issued by expert work groups. This manuscript has synthesized relevant data in order to obtain a pragmatic and updated review regarding cognitive decline in PD, from milder stages to dementia. This text will summarize clinical features, diagnostic methodology, and therapeutic issues of clinical decline in PD. Relevant clinical genetic issues, including recent advances, will also be approached. PMID:22654785

    Although clinicopathologic correlation is critical in the diagnosis of early mycosis fungoides (MF), how clinical information directly affects the pathologist's interpretation is unknown. This pilot study aimed to assess the influence of provided clinical information and specific histopathologic features on the histopathologic diagnosis of MF vs. its inflammatory simulants. A computerized survey recorded diagnostic impressions by 24 dermatopathologists of 30 hematoxylin-eosin stained images, including 15 MF images and 15 dermatitis images. Images were accompanied by concordant clinical descriptions (33%), no clinical information (33%) or discordant clinical descriptions (33%). Percentage of correctly classified MF histopathologic images for the three scenarios of concordant clinical information, no clinical information or discordant clinical information were 32% (kappa 0.19), 56% (kappa 0.12) and 16% (kappa 0.33), respectively. The percentage of correctly classified slides presented with no clinical information was different from the other two groups (p < 0.0001). Pautrier collections were most associated with correct classification. Clinical information may play a significant role in the histopathologic diagnosis of MF, although there may be some value in initial blinded histopathologic interpretation. Specific histopathologic features differ in relative importance in the diagnosis of MF.

  3. A Comparison of Passive Aggressive and Negativistic Personality Disorders

    Hopwood, Christopher J.; Wright, Aidan G.C.

    2012-01-01

    Passive aggressive personality disorder (PAPD) has historically played an important role in clinical theorizing and was diagnosable prior to the DSM-IV, in which the construct was relabeled ‘negativistic’, expanded to include negative affective symptoms, and appendicized. In this study we tested the hypothesis that the expansion of PAPD to include content related to negative moods and non-specific personality pathology compromised its discriminant validity. In an undergraduate sample (N = 1215), a self-report measure of PAPD was only moderately related to NEGPD and showed less diagnostic overlap with other PDs than NEGPD. Furthermore, a conjoint factor analysis yielded a strong first factor (moodiness) which appeared less specific to passive aggressive behavior than three other factors (irresponsibility, inadequacy and contempt). We conclude that future research on this potentially important clinical construct should focus on core passive aggressive features and abandon the negativistic content that has been added to it in successive editions of the DSM.

    Lung cancer, one of the leading causes of cancer-related deaths, usually appears as solitary pulmonary nodules (SPNs) which are hard to diagnose using the naked eye. In this paper, curvelet-based textural features and clinical parameters are used with three prediction models [a multilevel model, a least absolute shrinkage and selection operator (LASSO) regression method, and a support vector machine (SVM)] to improve the diagnosis of benign and malignant SPNs. Dimensionality reduction of the original curvelet-based textural features was achieved using principal component analysis. In addition, non-conditional logistical regression was used to find clinical predictors among demographic parameters and morphological features. The results showed that, combined with 11 clinical predictors, the accuracy rates using 12 principal components were higher than those using the original curvelet-based textural features. To evaluate the models, 10-fold cross validation and back substitution were applied. The results obtained, respectively, were 0.8549 and 0.9221 for the LASSO method, 0.9443 and 0.9831 for SVM, and 0.8722 and 0.9722 for the multilevel model. All in all, it was found that using curvelet-based textural features after dimensionality reduction and using clinical predictors, the highest accuracy rate was achieved with SVM. The method may be used as an auxiliary tool to differentiate between benign and malignant SPNs in CT images. PMID:24289618

    Atypical antipsychotic drugs have been used off-label in clinical practice for treatment of serious dementia-associated agitation and aggression. Following reports of cerebrovascular adverse events associated with the use of atypical antipsychotic in elderly patients with dementia, the FDA issued black box warnings for several atypical antipsychotics, titled “Cerebrovascular Adverse Events, including Stroke, in Elderly Patients with Dementia.” Subsequently, the FDA initiated a meta-analysis of safety data from 17 registration trials across six antipsychotic drugs (five atypical antipsychotics and haloperidol). In 2005, the Agency issued a black box warning regarding increased risk of mortality associated with the use of atypical antipsychotic drugs in this patient population. Geriatric mental health experts participating in a 2006 consensus conference reviewed evidence on the safety and efficacy of antipsychotics, as well as nonpharmacologic approaches, in treating dementia-related symptoms of agitation and aggression. They concluded that, while problems in clinical trials design may have been one of the contributors to the failure to find a signal of drug efficacy, the findings related to drug safety should be taken seriously by clinicians in assessing the potential risks and benefits of treatment in a frail population, and in advising families about treatment. Information provided to patients and family members should be documented in the patient’s chart. Drugs should be used only when non-pharmacologic approaches have failed to adequately control behavioral disruption. Participants also agreed that that there is a need for an FDA-approved medication for the treatment of severe, persistent or recurrent dementia-related symptoms of agitation and aggression (even in the absence of psychosis), that are unresponsive to nonpharmacologic intervention. The authors have outlined methodological enhancements to better evaluate treatment approaches in future

    Biomedical big data, as a whole, covers numerous features, while each dataset specifically delineates part of them. "Full feature spectrum" knowledge discovery across heterogeneous data sources remains a major challenge. We developed a method called bootstrapping for unified feature association measurement (BUFAM) for pairwise association analysis, and relational dependency network (RDN) modeling for global module detection on features across breast cancer cohorts. Discovered knowledge was cross-validated using data from Wake Forest Baptist Medical Center's electronic medical records and annotated with BioCarta signaling signatures. The clinical potential of the discovered modules was exhibited by stratifying patients for drug responses. A series of discovered associations provided new insights into breast cancer, such as the effects of patient's cultural background on preferences for surgical procedure. We also discovered two groups of highly associated features, the HER2 and the ER modules, each of which described how phenotypes were associated with molecular signatures, diagnostic features, and clinical decisions. The discovered "ER module", which was dominated by cancer immunity, was used as an example for patient stratification and prediction of drug responses to tamoxifen and chemotherapy. BUFAM-derived RDN modeling demonstrated unique ability to discover clinically meaningful and actionable knowledge across highly heterogeneous biomedical big data sets.

    Ghrelin system comprises a complex family of peptides, receptors (GHSRs), and modifying enzymes [e.g. ghrelin-O-acyl-transferase (GOAT)] that control multiple pathophysiological processes. Aberrant alternative splicing is an emerging cancer hallmark that generates altered proteins with tumorigenic capacity. Indeed, In1-ghrelin and truncated-GHSR1b splicing variants can promote development/progression of certain endocrine-related cancers. Here, we determined the expression levels of key ghrelin system components in neuroendocrine tumor (NETs) and explored their potential functional role. Twenty-six patients with NETs were prospectively/retrospectively studied [72 samples from primary and metastatic tissues (30 normal/42 tumors)] and clinical data were obtained. The role of In1-ghrelin in aggressiveness was studied in vitro using NET cell lines (BON-1/QGP-1). In1-ghrelin, GOAT and GHSR1a/1b expression levels were elevated in tumoral compared to normal/adjacent tissues. Moreover, In1-ghrelin, GOAT, and GHSR1b expression levels were positively correlated within tumoral, but not within normal/adjacent samples, and were higher in patients with progressive vs. with stable/cured disease. Finally, In1-ghrelin increased aggressiveness (e.g. proliferation/migration) of NET cells. Altogether, our data strongly suggests a potential implication of ghrelin system in the pathogenesis and/or clinical outcome of NETs, and warrant further studies on their possible value for the future development of molecular biomarkers with diagnostic/prognostic/therapeutic value.

    1995-02-27

    Early onset familial Alzheimer`s disease (AD) has an autosomal dominant mode of inheritance. Two genes are responsible for the majority of cases of this subtype of AD. Mutations in the {beta}-amyloid precursor protein ({beta}APP) gene on chromosome 21 have been shown to completely cosegregate with the disease. We and others have previously described the clinical features of families with {beta}APP mutations at the codon 717 locus in an attempt to define the phenotype associated with a valine to isoleucine (Val {r_arrow} Ile) or a valine to glycine (Val {r_arrow} Gly) change. More recently, a second locus for very early onset disease has been localized to chromosome 14. The results of linkage studies in some families suggesting linkage to both chromosomes have been explained by the suggestion of a second (centromeric) locus on chromosome 21. Here we report the clinical features and genetic analysis of a British pedigree (F74) with early onset AD in which neither the {beta}APP locus nor any other chromosome 21 locus segregates with the disease, but in which good evidence is seen for linkage on the long arm of chromosome 14. In particular we report marker data suggesting that the chromosome 14 disease locus is close to D14S43 and D14S77. Given the likelihood that F74 represents a chromosome 14 linked family, we describe the clinical features and make a limited clinical comparison with the {beta}APP717 Val {r_arrow} Ile and {beta}APP717 Val {r_arrow} Gly encoded families that have been previously described. We conclude that although several previously reported clinical features occur to excess in early onset familial AD, no single clinical feature demarcates either the chromosome 14 or {beta}APP codon 717 mutated families except mean age of onset. 52 refs., 2 figs., 5 tabs.

    Background. Gastric cancer is discovered even after successful eradication of H. pylori. We investigated clinic pathological features of early gastric cancers after H. pylori eradication. Methods. 51 early gastric cancers (EGCs) from 44 patients diagnosed after successful H. pylori eradication were included as eradication group. The clinic-pathological features were compared with that of 131 EGCs from 120 patients who did not have a history of H. pylori eradication (control group). Results. Compared with control group, clinic-pathological features of eradication group were characterized as depressed (p < 0.0001), reddish (p = 0.0001), and smaller (p = 0.0095) lesions, which was also confirmed in the comparison of six metachronous lesions diagnosed after initial ESD and subsequent successful H. pylori eradication. Prevalence of both SM2 (submucosal invasion greater than 500 μm) and unexpected SM2 cases tended to be higher in eradication group (p = 0.077, 0.0867, resp.). Prevalence of inconclusive diagnosis of gastric cancer during pretreatment biopsy was also higher in the same group (26.0% versus 1.6%, p < 0.0001). Conclusions. Informative clinic pathological features of EGC after H. pylori eradication are depressed, reddish appearances, which should be treated as a caution because histological diagnosis of cancerous tissue is sometimes difficult by endoscopic biopsy.

    We designed and tested a novel hybrid statistical model that accepts radiologic image features and clinical variables, and integrates this information in order to automatically predict abnormalities in chest computed-tomography (CT) scans and identify potentially important infectious disease biomarkers. In 200 patients, 160 with various pulmonary infections and 40 healthy controls, we extracted 34 clinical variables from laboratory tests and 25 textural features from CT images. From the CT scans, pleural effusion (PE), linear opacity (or thickening) (LT), tree-in-bud (TIB), pulmonary nodules, ground glass opacity (GGO), and consolidation abnormality patterns were analyzed and predicted through clinical, textural (imaging), or combined attributes. The presence and severity of each abnormality pattern was validated by visual analysis of the CT scans. The proposed biomarker identification system included two important steps: (i) a coarse identification of an abnormal imaging pattern by adaptively selected features (AmRMR), and (ii) a fine selection of the most important features from the previous step, and assigning them as biomarkers, depending on the prediction accuracy. Selected biomarkers were used to classify normal and abnormal patterns by using a boosted decision tree (BDT) classifier. For all abnormal imaging patterns, an average prediction accuracy of 76.15% was obtained. Experimental results demonstrated that our proposed biomarker identification approach is promising and may advance the data processing in clinical pulmonary infection research and diagnostic techniques.

    BACKGROUND We recently described the Mycobacterium tuberculosis RDRio genotype, a clonally derived sublineage within the Latin American–Mediterranean (LAM) family. Genetic diversity of M. tuberculosis likely affects the clinical aspects of tuberculosis (TB). Prospective studies that address this issue are scarce and remain controversial. OBJECTIVE To determine the association of differential clinical features of pulmonary TB with the RDRio M. tuberculosis etiology. METHODS Culture-proven pulmonary TB patients (n = 272) were clinically evaluated, including history, physical examination, chest X-ray and anti-human immunodeficiency virus serology. Isolates were classified as RDRio or non-RDRio M. tuberculosis by multiplex polymerase chain reaction and further spoligotyped. Clinical and M. tuberculosis genotype data were analyzed. RESULTS RDRio M. tuberculosis caused disease in 26.5% (72/270) of all TB cases. The LAM genotype, of which RDRio strains are members, was responsible for 46.0% of the TB cases. Demographic data, major signs and symptoms, radiographic presentation, microbiological features and clinical outcomes were not significantly different among patients with TB caused by RDRio and non-RDRio strains. CONCLUSIONS Disease caused by M. tuberculosis RDRio strains was not clinically distinctive or more severe than disease caused by non-RDRio strains in this series of TB patients. Larger prospective studies specifically designed to disclose differential clinical characteristics of TB caused by specific M. tuberculosis lineages are needed. PMID:22863208

  17. Cauda equina syndrome as the initial presenting clinical feature of medulloblastoma: a case report

    PubMed Central

    2012-01-01

    Introduction Medulloblastoma is one of the most common pediatric brain malignancies. The usual presenting clinical features are related to posterior fossa syndrome or/and hydrocephalus. Cauda equina syndrome is a very rare presentation for this disease. Case presentation We describe the case of a three-year-old boy with cauda equina syndrome as the initial presenting clinical feature for medulloblastoma. He was initially diagnosed as having a spinal tumor by magnetic resonance imaging scan. Subsequently, a cranial magnetic resonance imaging scan revealed a posterior fossa tumor with features of dissemination. He had substantial improvement after treatment. This case report is complemented by a literature review related to this unusual presentation. Conclusions Medulloblastoma primarily presenting with cauda equina syndrome is very rare. However, spinal drop metastasis should be considered in the pediatric age group to avoid suboptimal management. PMID:22620685

    Brucellosis is a zoonotic infection and has endemic characteristics. Neurobrucellosis is an uncommon complication of this infection. The aim of this study was to present unusual clinical manifestations and to discuss the management and outcome of a series of 18 neurobrucellosis cases. Initial clinical manifestations consist of pseudotumor cerebri in one case, white matter lesions and demyelinating syndrome in three cases, intracranial granuloma in one case, transverse myelitis in two cases, sagittal sinus thrombosis in one case, spinal arachnoiditis in one case, intracranial vasculitis in one case, in addition to meningitis in all cases. Eleven patients were male and seven were female. The most prevalent symptoms were headache (83%) and fever (44%). All patients were treated with rifampicin, doxycycline plus trimethoprim-sulfamethoxazole or ceftriaxone. Duration of treatment (varied 3-12 months) was determined on basis of the CSF response. In four patients presented with left mild sequelae including aphasia, hearing loss, hemiparesis. In conclusion, although mortality is rare in neurobrucellosis, its sequelae are significant. In neurobrucellosis various clinical and neuroradiologic signs and symptoms can be confused with other neurologic diseases. In inhabitants or visitors of endemic areas, neurobrucellosis should be kept in mind in cases that have unusual neurological manifestations.

    Background Congenital insensitivity to pain (CIP) is a rare extreme phenotype characterised by an inability to perceive pain present from birth due to lack of, or malfunction of, nociceptors. PRDM12 has recently been identified as a new gene that can cause CIP. The full phenotype and natural history have not yet been reported. Methods We have ascertained five adult patients and report their clinical features. Results Based on our findings, and those of previous patients, we describe the natural history of the PRDM12-CIP disorder, and derive diagnostic and management features to guide the clinical management of patients. Conclusions PRDM12-CIP is a distinct and diagnosable disorder, and requires specific clinical management to minimise predictable complications. PMID:26975306

    Objective Wrist injuries are a common presentation to the emergency department (ED). There are no validated decision rules to help clinicians evaluate paediatric wrist trauma. This study aimed to identify which clinical features are diagnostically useful in deciding the need for a wrist radiograph, and then to develop a clinical decision rule. Methods This prospective cohort study was carried out in the ED of Sheffield Children's Hospital. Eligible patients were recruited if presenting within 72 hours following blunt wrist trauma. A standardised data collection form was completed for all patients. The outcome measure was the presence or absence of a fracture. Univariate analysis was performed with the χ2 test. Associated variables (p<0.2) were entered into a multivariate model. Classification and regression tree (CART) analysis was used to derive the clinical decision rule. Results In total, 227 patients were recruited and 106 children were diagnosed with fractures (47%). Of 10 clinical features analysed, six were found by univariate analysis to be associated with a fracture. CART analysis identified the presence of radial tenderness, focal swelling, or an abnormal supination/pronation as the best discriminatory features. Cross fold validation of this decision rule had a sensitivity of 99.1% (95% confidence interval 94.8% to 100%) and a specificity of 24.0% (17.2% to 32.3%). The radiography rate would be 87%. Conclusions Radial tenderness, focal swelling, and abnormal supination/pronation are associated with wrist fractures in children. The clinical decision rule derived from these features had a high sensitivity, but low specificity, and would not substantially alter our current radiography rate. The potential for a clinical decision rule for paediatric wrist trauma appears limited. PMID:16627835

    Objectives Data on breast squamous cell carcinoma (SCC) are rare. The aim of this study was to analyze the clinical characteristics and to explore the rational treatment of patients with breast SCC. Patients and methods We conducted a retrospective review of breast SCC cases treated at our center from 1966 to 2014. The majority of these patients received primary surgery followed by adjuvant chemoradiotherapy, whilst four elderly patients had lumpectomy only. Results Patients with breast SCC were usually women, and large masses, large proportion of early stage disease, low levels of estrogen receptor expression, less frequent axillary lymph nodes involvement, and unfavorable prognosis were common. The 5-year overall survival and progression-free survival of all patients were 67.2% and 57.8%, respectively. Axillary nodal involvement was a significant prognostic factor for survival. Conclusion The current results indicated that breast SCC is clinically aggressive and the outcomes were poor. Distant metastasis was the main failure pattern. New strategies will be needed because of the poor outcomes. PMID:27313463

    22q11 Deletion Syndrome (22q11DS) is a common microdeletion syndrome with multisystem expression. Phenotypic features vary with age, ascertainment, and assessment. We systematically assessed 78 adults (36 M, 42 F; mean age 31.5, SD 10.5 years) with a 22q11.2 deletion ascertained through an adult congenital cardiac clinic (n = 35), psychiatric-related sources (n = 39), or as affected parents of subjects (n = 4). We recorded the lifetime prevalence of features requiring attention, with 95% confidence intervals (CI) not overlapping zero. Subtle learning difficulties, hypernasality and facial gestalt were not included. We investigated ascertainment effects using non-overlapping subgroups ascertained with tetralogy of Fallot (n = 31) or schizophrenia (n = 31). Forty-three features met inclusion criteria and were present in 5% or more patients, including several of later onset (e.g., hypothyroidism, cholelithiasis). Number of features per patient (median 9, range 3–22) correlated with hospitalizations (P=0.0002) and, when congenital features were excluded, with age (P=0.02). Adjusting for ascertainment, 25.8% (95% CI, 9.5–42.1%) of patients had cardiac anomalies and 22.6% (95% CI, 7.0–38.2%) had schizophrenia. Ascertainment subgroups were otherwise similar in median number and prevalence of features. Non-characteristic features are common in 22q11DS. Adjusting for ascertainment effects is important. Many treatable conditions may be anticipated and features may accumulate over time. The results have implications for clinical assessment and management, genetic counseling and research into pathophysiological mechanisms. PMID:16208694

    Mitochondrial encephalopathy with lactic acidosis and stroke-like episodes (MELAS) mostly occur in children. The point mutation A3243G of mitochondrial DNA (mtDNA) may work as a specific bio-marker for mitochondrial disorders. The related clinical features, however, may vary among individuals. This study therefore investigated the relation between MELAS clinical features and point mutation A3243G of mtDNA, in an attempt to provide further evidences for genetic diagnosis of MELAS. Children with MELAS-like syndromes were tested for both blood lactate level and point mutation A3243G of mtDNA. Further family study was performed by mtDNA mutation screening at the same loci for those who had positive gene mutation at A3243G loci. Those who were negative for A3243G point mutation were examined by muscle biopsy and genetic screening. Both clinical and genetic features were analyzed. In all 40 cases with positive A3243G mutation, 36 children fitted clinical diagnosis of MELAS. In other 484 cases with negative mutation, only 8 children were clinically diagnosed with MELAS. Blood lactate levels in both groups were all elevated (P>0.05). In a further genetic screening of 28 families, 10 biological mothers and 8 siblings of MELAS children had positive A3243G point mutations but without any clinical symptoms. Certain difference existed in the clinical manifestations between children who were positive and negative for A3243G mutation of mtDNA but without statistical significance. MELAS showed maternal inheritance under most circumstances.

    From March 2008 through February 2014, 80 patients aged 1-95 years (43 men and 37 women) were diagnosed with tinea faciei by a rural Japanese clinic. The affected sites were the cheek in 42 patients (52.5%), the auricles and area surrounding the auricles in 16 (20.0%), and the mandible in 12 (15.0%); 33 patients (41.2%) had concurrent ringworm in areas other than the face. Twenty-one patients (26.3%) had applied topical steroids to treat a rash. The pathogen responsible for tinea faciei was Trichophyton rubrum in 35 patients (43.7%), T. tonsurans in 19 (23.8%), T. mentagrophytes in 3 (3.8%), T. verrucosum in 2 (2.5%), T. violaceum in 2 (2.5%), Microsporum canis in 17 (21.3%), and M. gypseum in 2 (2.5%). Clinical symptoms were divided into three groups based on the severity of inflammation and the extent of lesions and scored in points. Anthropophilic dermatophytes resulted in a score of 1.82 points for the severity of inflammation and a score of 1.84 points for the extent of lesions while zoophilic dermatophytes resulted in a score of 2.14 points for the severity of inflammation and a score of 1.50 points for the extent of lesions. This indicates that anthropophilic fungi resulted in less inflammation and broader lesions, whereas zoophilic fungi resulted in more intense inflammation and smaller lesions. Patients who had applied topical steroids had a mean score of 1.90 points for the severity of inflammation and a mean score of 2.10 points for the extent of lesions. Patients who had not applied topical steroids had a mean score of 1.95 points for the severity of inflammation and a mean score of 1.59 points for the extent of lesions. The severity of inflammation did not differ significantly. However, lesions were significantly broader in patients who had applied topical steroids than in those who had not applied topical steroids (p < 0.04). The severity of tinea faciei is a useful index for the clinical diagnosis of tinea faciei.

    Aim: The aim of work was presentation of several socio-demographic, clinical and laboratory characteristics of gastroenteritis caused by rotavirus. The examinees and methods: The examinees were children under the age of five years treated at the Pediatric Clinic due to acute gastroenteritis caused by rotavirus. Rotavirus is isolated by method chromatographic immunoassay by Cer Test Biotec. Results: From the total number of patients (850) suffering from acute gastroenteritis, feces test on bacteria, viruses. protozoa and fungi was positive in 425 (49.76%) cases. From this number the test on bacteria was positive in 248 (58.62%) cases, on viruses it was positive in 165 (39.0%), on protozoa in 9 (2.12%) cases and on fungi only one case. Rotavirus was the most frequent one in viral test, it was isolated in 142 (86.06%) cases, adenoviruses were found in 9 (5.45%) cases and noroviruses in only one case. The same feces sample that contained rotavirus and adenoviruses were isolated in five cases, whereas rotavirus with bacteria was isolated in the same feces sample in five cases. The biggest number of cases 62 (43.66%) were of the age 6-12 months, whereas the smallest number 10 (7.04%) cases were of the age 37-60 months. There were 76 (53.52%) of cases of male gender, from rural areas there were 81 (57.04%) cases and there were 58 (40.80%) cases during the summer period. Among the clinical symptoms the most prominent were diarrhea, vomiting, high temperature, whereas the different degree of dehydration were present in all cases (the most common one was moderate dehydration). The most frequent one was isonatremic dehydration in 91 (64.08%) cases, less frequent one was hypernatremic dehydration in 14 (9.85%) cases. The majority of cases (97.89%) had lower blood pH values, whereas 67 (47.17%) cases had pH values that varied from 7.16 -7.20 (curve peak), normal values were registered in only 3 (2.11%) cases. Urea values were increased in 45 (31.07%) cases (the maximum value

    AIM To investigate the incidence of achalasia in Algeria and to determine its clinical and para-clinical profile. To evaluate the impact of continuing medical education (CME) on the incidence of this disease. METHODS From 1990 to 2014, 1256 patients with achalasia were enrolled in this prospective study. A campaign of CME on diagnosis involving different regions of the country was conducted between 1999 and 2003. Annual incidence and prevalence were calculated by relating the number of diagnosed cases to 105 inhabitants. Each patient completed a standardized questionnaire, and underwent upper endoscopy, barium swallow and esophageal manometry. We systematically looked for Allgrove syndrome and familial achalasia. RESULTS The mean annual incidence raised from 0.04 (95%CI: 0.028-0.052) during the 1990s to 0.27/105 inhabitants/year (95%CI: 0.215-0.321) during the 2000s. The incidence of the disease was two and half times higher in the north and the center compared to the south of the country. One-hundred-and-twenty-nine (10%) were children and 97 (7.7%) had Allgrove syndrome. Familial achalasia was noted in 18 different families. Patients had dysphagia (99%), regurgitation (83%), chest pain (51%), heartburn 24.5% and weight loss (70%). The lower esophageal sphincter was hypertensive in 53% and hypotensive in 0.6%. CONCLUSION The mean incidence of achalasia in Algeria is at least 0.27/105 inhabitants. A good impact on the incidence of CME was noted. A gradient of incidence between different regions of the country was found. This variability is probably related to genetic and environmental factors. The discovery of an infantile achalasia must lead to looking for Allgrove syndrome and similar cases in the family. PMID:27784974

    We report a patient who presented with clinical and MRI findings suggestive of polymyositis but, in whom, muscle biopsy disclosed a strikingly different diagnosis. A 65-year-old woman presented with 3-week history of bilateral proximal muscle pain and weakness. Laboratory investigations showed markedly elevated inflammatory markers and mildly elevated muscle enzymes. MRI scans of lower limbs showed features suggestive of polymyositis. However, muscle biopsy showed features of a polyarteritis-type vasculitis affecting an intramuscular blood vessel. Our reports highlight the critical role of muscle biopsy in establishing the correct diagnosis in patients with suspected myositis.

    Oral-facial-digital syndrome type I (OFDI) is an X-linked syndrome, which has several craniofacial and limb features; and hence, patients frequently present to craniofacial and plastic surgeons. Oral-facial-digital syndrome type I is caused by mutations in the CXORF5 gene. The gene product is one of the basal body proteins of a slim microtubule-based organelle called the “primary cilium”. Most of the clinical features of OFDI patients are related to dysfunctions of the primary cilium leading to abnormal Hedgehog signal transduction, depressed planar cell polarity pathway, and errors in cell cycle control.

    Benign by nature, aggressive fibromatoses (desmoid fibromas) may represent as difficult therapeutic problems as malignant tumours. When subtotally resected they tend to recur. But spontaneous regression is possible. Expense and limits of their surgical treatment are discussed with reference to seven patients. In five cases primary affliction of bone was evident. There are three reports given in detail: In the first, malignant transformation may be due to radiation therapy and hemipelvectomy could not prevent recurrence. In the second, spontaneous regression of untreated pelvic affection may have occurred. In the third, several resections and amputation of the leg failed to cure congenital infantile fibromatosis.

    Ink spot lentigo, also known as reticulated black solar lentigo, is a melanotic macula commonly described in fair-skinned individuals on sun-exposed areas of the body. Clinically it is a darkly pigmented type of solar lentigo; herein the term ink spot lentigo. In contrast to common solar lentigines, ink spot lentigo is reported as a unique lesion. However usually ink spot lentigo appears among several common solar lentigines. We report a series of 5 patients who presented ink spot lentigo with typical dermoscopic pattern but singular clinical features.

    In patients with meningococcal infection, devastating presentations, such as purpura fulminans, which can progress to extensive tissue necrosis of the limbs and digits, have a significant social impact. The case presented herein illustrates such a phenomenon in a patient who developed bilateral necrosis of the lower extremities as a result of infection with Neisseria meningitis. We emphasize that severe myalgia was the first clinical manifestation of meningococcal purpura fulminans in our case. However, myalgia has typically been overlooked and undervalued as an early clinical feature of meningococcal sepsis. Early recognition and prompt initial antibiotic therapy continue to be the cornerstones of the successful management of this dramatic disease, reducing morbidity and mortality.

    Juvenile myelomonocytic leukemia (JMML) is a rare clonal myeloproliferative disorder of childhood. Major progress has been achieved in diagnosis and the understanding of the pathogenesis of JMML by identifying the genetic pathologies that occur in patients. Mutations of RAS, NF1, PTPN11, and CBL are found in approximately 80% of JMML patients. Distinct clinical features have been reported to be associated with specific gene mutations. The advent of genomic studies and recent identification of novel genetic mutations in JMML are important not only in diagnosis but also in the management and prognosis of the disease. Herein, we present 2 patients with JMML harboring different mutations, NRAS and c-CBL, respectively, with distinct clinical features and different therapeutic approaches.

    Neurodegeneration with brain iron accumulation (NBIA) represents a heterogeneous and complex group of inherited neurodegenerative diseases, characterized by excessive iron accumulation, particularly in the basal ganglia. Common clinical features of NBIA include movement disorders, particularly parkinsonism and dystonia, cognitive dysfunction, pyramidal signs, and retinal abnormalities. The forms of NBIA described to date include pantothenase kinase-associated neurodegeneration (PKAN), phospholipase A2 associated neurodegeneration (PLAN), neuroferritinopathy, aceruloplasminemia, beta-propeller protein-associated neurodegeneration (BPAN), Kufor-Rakeb syndrome, mitochondrial membrane protein-associated neurodegeneration (MPAN), fatty acid hydroxylase-associated neurodegeneration (FAHN), coenzyme A synthase protein-associated neurodegeneration (CoPAN) and Woodhouse-Sakati syndrome. This review is a diagnostic approach for NBIA cases, from clinical features and brain imaging findings to the genetic etiology.

    The study was done to assess correlation between serology and clinical features of Dengue fever at Burdwan Medical College, where after clinical examination, blood samples were processed by E.I.A. Of 139 cases, mostly between 1 to 20 years, Male-Female ratio was 80:59. Bleeding manifestation was observed only in 3 cases, and Lymphadenopathy, Myocarditis were uncommon features. Few patients have biphasic temperature. Fever and severity of symptoms did not have correlation. Patients' blood was examined for Dengue viruses, with only 44.6% positivity. Correlation exists between illness duration and antibody titer. [r = 0.41; (P < 0.01)]. Fever other, than Dengue also exhibited similar symptoms, but optical density in EIA test was less. As high fever with similar symptoms may be due to causes other than Dengue, thorough search for other viral infection namely Chikungunya should be done in endemic areas also.

    Middle school is a critical yet understudied period of social behavioral risks and opportunities that may be particularly difficult for emerging adolescents with attention-deficit/hyperactivity disorder (ADHD) given their childhood social difficulties. Relatively few ADHD studies have examined social behavior and social-cognitive problem solving beyond the elementary years, or examined aspects of positive (prosocial) behavior. The current study examined how middle school students with clinically elevated ADHD symptoms differ from their non-ADHD peers on baseline (6th grade) and age-related changes in prosocial and aggressive behavior, and the extent to which social-cognitive problem solving strategies mediate these relations. Emerging adolescents with (n = 178) and without (n = 3,806) clinically elevated, teacher-reported ADHD-combined symptoms were compared longitudinally across 6th through 8th grades using parallel process latent growth curve modeling, accounting for student demographic characteristics, oppositional-defiant disorder (ODD) symptoms, deviant peer association, school climate, and parental monitoring. Sixth graders with elevated ADHD symptoms engaged in somewhat fewer prosocial behaviors (d = -0.44) and more aggressive behavior (d = 0.20) relative to their peers. These small social behavioral deficits decreased but were not normalized across the middle school years. Contrary to hypotheses, social-cognitive problem solving was not impaired in the ADHD group after accounting for co-occurring ODD symptoms and did not mediate the association between ADHD and social behavior during the middle school years. ADHD and social-cognitive problem solving contributed independently to social behavior, both in 6th grade and across the middle school years; the influence of social-cognitive problem solving on social behavior was highly similar for the ADHD and non-ADHD groups.

The FSGS Clinical Trial involved 138 children and young adults who were randomized to cyclosporin or mycophenolate mofetil plus pulse oral dexamethasone with a primary outcome of proteinuria remission. DNA was available from 94 subjects who were genotyped for APOL1 renal risk variants, with two risk alleles comprising the risk genotype. Two APOL1 risk alleles were present in 27 subjects, of whom four subjects did not self-identify as African American, and 23 of 32 (72%) self-identified African Americans. Individuals with the APOL1 risk genotype tended to present at an older age and had significantly lower baseline eGFR, more segmental glomerulosclerosis and total glomerulosclerosis, and more tubular atrophy/interstitial fibrosis. There were differences in renal histology, particularly more collapsing variants in those with the risk genotype (P=0.02), although this association was confounded by age. APOL1 risk genotype did not affect response to either treatment regimen. Individuals with the risk genotype were more likely to progress to ESRD (P<0.01). In conclusion, APOL1 risk genotypes are common in African-American subjects with primary FSGS and may also be present in individuals who do not self-identify as African American. APOL1 risk status is associated with lower kidney function, more glomerulosclerosis and interstitial fibrosis, and greater propensity to progress to ESRD. The APOL1 risk genotype did not influence proteinuria responses to cyclosporin or mycophenolate mofetil/dexamethasone. PMID:25573908

    In order to improve diagnosis of schizophrenia with onset in adolescents at an early stage, we investigated in detail the clinical features of 74 patients with schizophrenia, (23 males) at adolescents psychiatric clinic. Many of the subjects had been suffering from the illness about 14 years old but had not undergone their first psychiatric examination until a few years later. A high percentage (more than 80%) of our subjects presented psychiatric symptoms such as delusional remembrance, delusional moods, delusions of persecution and hypobulia. Additionally, more than 60% of our subjects presented auditory hallucinations. In general, teenage patients with schizophrenia onset show vague symptoms such as anxiety, embarrassment and strange moods rather than obvious hallucinations. Nevertheless, it was possible to identify certain clinical features of this disorder in adolescents: many patients suffer delusional remembrance, delusional moods and delusions of persecution immediately after the onset of the illness. Gradually, problematic behaviors such as anorexia, self injury, offences against their families, voluntary vomiting, etc., develop, but patients do not always receive psychiatric examination at this stage. After socially obvious problems such as school refusal, withdrawal from social activities and lowering of school record develop over a period of time, patients may be urged to undergo psychiatric examination. Our research again underlines the difficulty of achieving diagnosis of schizophrenia at an early stage. The key to early diagnosis appears to be the accurate identification of psychiatric symptoms in the early stages of the illness at school, or at home if possible, before socially problematic behaviors arise.

    Pernicious anemia is an autoimmune disease with a variety of clinical presentations. We describe a case of pernicious anemia presenting with pancytopenia with hemolytic features. Further workup revealed very low vitamin B12 levels and elevated methylmalonic acid. It is important for a general internist to identify pernicious anemia as one of the cause of pancytopenia and hemolytic anemia to avoid extensive workup. Pernicious anemia can present strictly with hematological abnormalities without neurological problems or vice versa as in our case. PMID:27609735

    Basal cell carcinoma (BCC) is the most common malignancy. Exposure to sunlight is the most important risk factor. Most, if not all, cases of BCC demonstrate overactive Hedgehog signaling. A variety of treatment modalities exist and are selected based on recurrence risk, importance of tissue preservation, patient preference, and extent of disease. The pathogenesis, epidemiology, clinical features, diagnosis, histopathology, and management of BCC will be discussed in this review. PMID:26029015

    Chondroid syringoma is a generally benign, adnexal tumor most commonly found in the head and neck. It is typically diagnosed retrospectively from histopathology, and careful evaluation must differentiate it from tumors of salivary gland origin. It presents as a slowly growing, subcutaneous or intradermal nodule. Treatment consists of wide local excision with a margin of normal tissue. We report a case involving a 51-year-old man with a chondroid syringoma arising from the scalp. Clinical features, histopathology, and treatment are discussed.

    Deletions of the long arm of the Y chromosome have previously been associated with azoospermia and short stature. We report the results of a detailed clinical and molecular study of nine males with partial deletions of Yq. Special emphasis was laid on congenital anomalies and dysmorphic features. Some of the patients have developmental problems or distinct facial features, namely a small chin and mouth, a high arched or cleft palate, downward slanting palpebral fissures, high nasal bridge, and dysmorphic ears. As far as we know, similar facial dysmorphism has not been previously described in association with del(Yq). These features are not, however, simply correlated to the size of the deletion. In none of these patients could evidence of aberrant Xq-Yq interchange be found.

    Prader-Willi Syndrome (PWS) is estimated to affect 400,000 people worldwide. First described clinically in 1956, PWS is now known to be a result of a genetic mutation, involving Chromosome 15. The phenotypical appearance of individuals with the syndrome follows a similar developmental course. During infancy, universal hypotonia accompanied by feeding problems, hypogonadism, and dolichocephaly are evident. Characteristic facial features such as narrow bifrontal diameter, almond-shaped eyes, and small mouth (with downturned corners and thin upper lip) may also be evident at this stage. In early childhood, the craniofacial features become more obvious and a global developmental delay is observed. Simultaneously, individuals develop hyperphagia that leads to excessive or rapid weight gain, which, if untreated, exists throughout their lifespan and may predispose them to numerous, serious health issues. The standard tool for differential diagnosis of PWS is genetic screening; however, clinicians also need to be aware of the characteristic features of this disorder, including differences between the genetic subtypes. As the clinical manifestations of the syndrome vary between individuals and become evident at different developmental time points, early assessment is hindered. This article focuses on the clinical and anatomical manifestations of the syndrome and highlights the areas of discrepancy and limitations within the existing literature. Clin.

    The occurrence of heart failure (HF) and its clinical features after a great disaster have not been rigorously examined. We retrospectively examined the effect of the Great East Japan Earthquake on the occurrence of decompensated HF. The number of patients admitted for treatment of decompensated HF and their clinical features were compared between 2 periods, March 11, 2011 to September 10, 2011 (after the earthquake) and the same period in the previous year. The number of admissions increased from 55 in 2010 to 84 in 2011. A comparison of the clinical features showed that the patients admitted after the earthquake had (1) older age (p = 0.031), (2) greater systolic blood pressure (p = 0.039), (3) a greater incidence of new-onset HF due to valvular heart disease (p = 0.040), (4) interruption of drugs (p = 0.001), (5) a greater incidence of infection (p = 0.019), (6) greater B-type natriuretic peptide (p = 0.005) and C-reactive protein (p = 0.003) levels, (7) a lower estimated glomerular filtration rate (p = 0.048) and lower albumin levels (p = 0.021), and (8) a larger diameter of the inferior vena cava (p = 0.008). In conclusion, these results suggest that the earthquake increased the incidence of HF in association with high blood pressure, interruption of drugs, inflammation, malnutrition, and fluid retention. Taking appropriate measures to control blood pressure, nutritional status, and hygiene environment might decrease the occurrence of HF in future disasters.

    Solitary rectal ulcer syndrome (SRUS) is an uncommon benign disease, characterized by a combination of symptoms, clinical findings and histological abnormalities. Ulcers are only found in 40% of the patients; 20% of the patients have a solitary ulcer, and the rest of the lesions vary in shape and size, from hyperemic mucosa to broad-based polypoid. Men and women are affected equally, with a small predominance in women. SRUS has also been described in children and in the geriatric population. Clinical features include rectal bleeding, copious mucus discharge, prolonged excessive straining, perineal and abdominal pain, feeling of incomplete defecation, constipation, and rarely, rectal prolapse. This disease has well-described histopathological features such as obliteration of the lamina propria by fibrosis and smooth muscle fibers extending from a thickened muscularis mucosa to the lumen. Diffuse collage deposition in the lamina propria and abnormal smooth muscle fiber extensions are sensitive markers for differentiating SRUS from other conditions. However, the etiology remains obscure, and the condition is frequently associated with pelvic floor disorders. SRUS is difficult to treat, and various treatment strategies have been advocated, ranging from conservative management to a variety of surgical procedures. The aim of the present review is to summarize the clinical features, pathophysiology, diagnostic methods and treatment strategies associated with SRUS.

    Each breast cancer has its unique spatial shape, but the clinical importance and the underlying mechanism for the three-dimensional tumor shapes are mostly unknown. We collected the data on the three-dimensional tumor size and tumor volume data of invasive breast cancers from 2,250 patients who underwent surgery between Jan 2000 and Jul 2007. The degree of tumor eccentricity was estimated by using the difference between the spheroid tumor volume and ellipsoid tumor volume (spheroid-ellipsoid discrepancy, SED). In 41 patients, transcriptome and exome sequencing data obtained. Estimation of more accurate tumor burden by calculating ellipsoid tumor volumes did not improve the outcome prediction when compared to the traditional longest diameter measurement. However, the spatial tumor eccentricity, which was measured by SED, showed significant variation between the molecular subtypes of breast cancer. Additionally, the degree of tumor eccentricity was associated with well-known prognostic factors of breast cancer such as tumor size and lymph node metastasis. Transcriptome data from 41 patients showed significant association between MMP13 and spatial tumor shapes. Network analysis and analysis of TCGA gene expression data suggest that MMP13 is regulated by ERBB2 and S100A7A. The present study validates the usefulness of the current tumor size method in determining tumor stages. Furthermore, we show that the tumors with high eccentricity are more likely to have aggressive tumor characteristics. Genes involved in the extracellular matrix remodeling can be candidate regulators of the spatial tumor shapes in breast cancer. PMID:26669540

    Fractures during clinical function have been reported as the major concern associated with all-ceramic dental restorations. The aim of this study was to analyze the fracture features of glass-ceramic and zirconia-based restorations fractured during clinical use. Twenty-seven crowns and onlays were supplied by dentists and dental technicians with information about type of cement and time in function, if available. Fourteen lithium disilicate glass-ceramic restorations and 13 zirconia-based restorations were retrieved and analyzed. Fractographic features were examined using optical microscopy to determine crack initiation and crack propagation of the restorations. The material comprised fractured restorations from one canine, 10 incisors, four premolars, and 11 molars. One crown was not categorized because of difficulty in orientation of the fragments. The results revealed that all core and veneer fractures initiated in the cervical margin and usually from the approximal area close to the most coronally placed curvature of the margin. Three cases of occlusal chipping were found. The margin of dental all-ceramic single-tooth restorations was the area of fracture origin. The fracture features were similar for zirconia, glass-ceramic, and alumina single-tooth restorations. Design features seem to be of great importance for fracture initiation.

    Rationale: The relationship between clinical phenotype of childhood primary ciliary dyskinesia (PCD) and ultrastructural defects and genotype is poorly defined. Objectives: To delineate clinical features of childhood PCD and their associations with ultrastructural defects and genotype. Methods: A total of 118 participants younger than 19 years old with PCD were evaluated prospectively at six centers in North America using standardized procedures for diagnostic testing, spirometry, chest computed tomography, respiratory cultures, and clinical phenotyping. Measurements and Main Results: Clinical features included neonatal respiratory distress (82%), chronic cough (99%), and chronic nasal congestion (97%). There were no differences in clinical features or respiratory pathogens in subjects with outer dynein arm (ODA) defects (ODA alone; n = 54) and ODA plus inner dynein arm (IDA) defects (ODA + IDA; n = 18) versus subjects with IDA and central apparatus defects with microtubular disorganization (IDA/CA/MTD; n = 40). Median FEV1 was worse in the IDA/CA/MTD group (72% predicted) versus the combined ODA groups (92% predicted; P = 0.003). Median body mass index was lower in the IDA/CA/MTD group (46th percentile) versus the ODA groups (70th percentile; P = 0.003). For all 118 subjects, median number of lobes with bronchiectasis was three and alveolar consolidation was two. However, the 5- to 11-year-old IDA/CA/MTD group had more lobes of bronchiectasis (median, 5; P = 0.0008) and consolidation (median, 3; P = 0.0001) compared with the ODA groups (median, 3 and 2, respectively). Similar findings were observed when limited to participants with biallelic mutations. Conclusions: Lung disease was heterogeneous across all ultrastructural and genotype groups, but worse in those with IDA/CA/MTD ultrastructural defects, most of whom had biallelic mutations in CCDC39 or CCDC40.

    Introduction To improve our understanding of sex differences in the clinical characteristics of Parkinson’s Disease, we sought to examine differences in the clinical features and disease severity of men and women with early treated Parkinson’s Disease (PD) enrolled in a large-scale clinical trial. Methods Analysis was performed of baseline data from the National Institutes of Health Exploratory Trials in Parkinson’s Disease (NET-PD) Long-term Study-1, a randomized, multi-center, double-blind, placebo-controlled study of 10 grams of oral creatine/day in individuals with early, treated PD. We compared mean age at symptom onset, age at PD diagnosis, and age at randomization between men and women using t-test statistics. Sex differences in clinical features were evaluated, including: symptoms at diagnosis (motor) and symptoms at randomization (motor, non-motor, and daily functioning). Results 1,741 participants were enrolled (62.5% male). No differences were detected in mean age at PD onset, age at PD diagnosis, age at randomization, motor symptoms, or daily functioning between men and women. Differences in non-motor symptoms were observed, with women demonstrating better performance compared to men on SCOPA-COG (Z = 5.064, p<0.0001) and Symbol Digit Modality measures (Z = 5.221, p<0.0001). Conclusions Overall, men and women did not demonstrate differences in clinical motor features early in the course of PD. However, the differences observed in non-motor cognitive symptoms suggests further assessment of the influence of sex on non-motor symptoms in later stages of PD is warranted. PMID:26171861

    Vibrio parahaemolyticus is a bacterial pathogen that can cause illness after the consumption or handling of contaminated seafood. The primary virulence factors associated with V. parahaemolyticus illness are thermostable direct hemolysin (TDH) and Tdh-related hemolysin (TRH). However, clinical strains lacking tdh and trh have recently been isolated, and these clinical isolates are poorly understood. To help understand the emergence of clinical tdh- and trh-negative isolates, a genomic approach was used to comprehensively compare 4 clinical tdh- and trh-negative isolates with 16 environmental tdh- and trh-negative isolates and 34 clinical isolates positive for tdh or trh, or both, with the objective of identifying genomic features that are unique to clinical tdh- and trh-negative isolates. The prevalence of pathogenicity islands (PAIs) common to clinical isolates was thoroughly examined in each of the clinical tdh- and trh-negative isolates. The tdh PAI was not present in any clinical or environmental tdh- and trh-negative isolates. The trh PAI was not present in any environmental isolates; however, in clinical tdh- and trh-negative isolate 10-4238, the majority of the trh PAI including a partial trh1 gene was present, which resulted in reclassification of this isolate as a tdh-negative and trh-positive isolate. In the other clinical tdh- and trh-negative isolates, neither the trh gene nor the trh PAI was present. We identified 862 genes in clinical tdh- and trh-negative isolates but not in environmental tdh- and trh-negative isolates. Many of these genes are highly homologous to genes found in common enteric bacteria and included genes encoding a number of chemotaxis proteins and a novel putative type VI secretion system (T6SS) effector and immunity protein (T6SS1). The availability of genome sequences from clinical V. parahaemolyticus tdh- and trh-negative isolates and the comparative analysis may help provide an understanding of how this pathotype is able to

    Vitiligo is an acquired, pigmentary skin disorder that affects about 0.1-4.0% of the population. In this study, we aimed to investigate the disease features such as age of onset, disease duration, clinical and sociodemographic characteristics, and laboratory parameters of patients with vitiligo. A hundred patients who were in follow-up for vitiligo between the period of June 2013 and May 2014 were included in the study. The clinical features and laboratory parameters were retrospectively obtained from the records of the patients. The mean age was 34.9±16.8 years. The most common clinical types were focal and acrofacial. Facial involvement was the most common localization. Forty-five (45%) patients had an associated systemic disease. Autoimmune thyroid disease, essential hypertension, and alopecia areata, which were observed in 28%, 8%, and 5% of patients, respectively, were the most common associated diseases. Twenty-one percent of the patients had low ferritin levels, 20% had low iron levels, 12% had low vitamin B12 levels, and 1% had low folic acid levels. The prevalence of anti-TG (anti-thyroglobulin) and anti-TPO (anti-thyroid peroxidase) antibodies were found 17% and 27% of the patients, respectively. We found that the clinical characteristics of vitiligo in our patients were similar to those in other studies. We observed laboratory abnormalities and accompanying diseases associated with vitiligo. Therefore we conclude that laboratory examinations including thyroid antibodies and regular follow-up of these patients are essential. PMID:27477172

    SUMMARY Contemporary clinical assessment of back pain is based on the diagnostic triage paradigm. The most common diagnostic classification is nonspecific back pain, considered to be of nociceptive etiology. A small proportion are diagnosed with radicular pain, of neuropathic origin. In this study we review the body of literature on the prevalence of neuropathic features of back pain, revealing that the point prevalence is 17% in primary care, 34% in mixed clinical settings and 53% in tertiary care. There is evidence that neuropathic features of back pain are not restricted to typical clinical radicular pain phenotypes and may be under-recognized, particularly in primary care. The consequence of this is that in the clinic, diagnostic triage may erroneously classify patients with nonspecific back pain or radicular pain. A promising alternative is the development of mechanism-based pain phenotyping in patients with back pain. Timely identification of contributory pain mechanisms may enable greater opportunity to select appropriate therapeutic targets and improve patient outcomes.

    The clinical features of 10 cases of lateral trunk muscle injury in first class cricket pace bowlers are described. Typically the injury occurs during a single delivery, is associated with considerable pain, and prevents the bowler from continuing. The clinical picture is typical of a muscular or musculotendinous injury. The most consistent clinical tests were focal tenderness on palpation and pain with resisted side flexion towards the painful side. The magnetic resonance image in 70% of cases was consistent with an injury to the internal oblique, the external oblique, or the transversalis muscles at or near their attachments to one or more of the lowest four ribs. The injury occurs on the non-bowling arm side. Recovery can be prolonged. The injury was a recurrence in six of the 10 cases. The biomechanics of the injury are not yet understood.

    Critical appraisal of the literature highlights that the discriminative power of gait-related features in patients with hip osteoarthritis (OA) has not been fully explored. We aimed to reduce the number of gait-related features and define the most discriminative ones comparing the three-dimensional gait analysis of 20 patients with hip osteoarthritis (OA) with those of 17 healthy peers. First, principal component analysis was used to reduce the high-dimensional gait data into a reduced set of interpretable variables for further analysis, including tests for group differences. These differences were indicative for the selection of the top 10 variables to be included into linear discriminant analysis models (LDA). Our findings demonstrated the successful data reduction of hip osteoarthritic-related gait features with a high discriminatory power. The combination of the top variables into LDA models clearly separated groups, with a maximum misclassification error rate of 19%, estimated by cross-validation. Decreased hip/knee extension, hip flexion and internal rotation moment were gait features with the highest discriminatory power. This study listed the most clinically relevant gait features characteristics of hip OA. Moreover, it will help clinicians and physiotherapists understand the movement pathomechanics related to hip OA useful in the management and design of rehabilitation intervention.

  19. Aggressive and acute periodontal diseases.

    Inflammatory periodontal diseases are highly prevalent, although most of these diseases develop and progress slowly, often unnoticed by the affected individual. However, a subgroup of these diseases include aggressive and acute forms that have a relatively low prevalence but show a rapid-course, high rate of progression leading to severe destruction of the periodontal tissues, or cause systemic symptoms that often require urgent attention from healthcare providers. Aggressive periodontitis is an early-onset, destructive disease that shows a high rate of periodontal progression and distinctive clinical features. A contemporary case definition of this disease is presented. Population studies show that the disease is more prevalent in certain geographic regions and ethnic groups. Aggressive periodontitis is an infectious disease, and recent data show that in affected subjects the subgingival microbiota is composed of a mixed microbial infection, with a wide heterogeneity in the types and proportions of microorganisms recovered. Furthermore, there are significant differences in the microbiota of the disease among different geographic regions and ethnicities. There is also evidence that the Aggregatibacter actinomycetemycomitans-JP2 clone may play an important role in the development of the disease in certain populations. The host response plays an important role in the susceptibility to aggressive periodontitis, where the immune response may be complex and involve multiple mechanisms. Also, genetic factors seem to play an important role in the pathogenesis of this disease, but the mechanisms of increased susceptibility are complex and not yet fully understood. The available data suggest that aggressive periodontitis is caused by mutations either in a few major genes or in multiple small-effect genes, and there is also evidence of gene-gene and gene-environment interaction effects.

    Background The limited form of Granulomatosis with Polyangiitis (GPA), formerly known as Wegener’s Granulomatosis (WG) primarily involves the head and neck region, including the orbit, but is often a diagnostic challenge, particularly as it commonly lacks positive anti-neutrophil cytoplasm antibody (ANCA) titres or classical features on diagnostic orbital biopsies. The purpose of this study was to relate biopsy findings with clinical outcome and to determine which histopathological features are predictive of a clinical diagnosis of GPA. Methods Retrospective case series of 234 patients identified from the database of the UCL Institute of Ophthalmology Department of Eye Pathology as having had orbital biopsies of orbital inflammatory disorders performed between 1988 and 2009. Clinical records were obtained for the patients and analysed to see whether patients had GPA or not, according to a standard set of diagnostic criteria (excluding any histopathological findings). Biopsy features were then correlated with the clinical diagnosis in univariate and multivariate analyses to determine factors predictive of GPA. Results Of the 234 patients, 36 were diagnosed with GPA and 198 with other orbital pathologies. The majority of biopsies were from orbital masses (47%). Histology showed a range of acute and chronic inflammatory pictures in all biopsies, but the presence of neutrophils (P<0.001), vasculitis (P<0.001), necrosis (P<0.001), eosinophils (P<0.02) and macrophages (P=0.05) were significantly associated with a later clinical diagnosis of GPA. In a multivariate analysis, only tissue neutrophils (OR=3.6, P=0.01) and vasculitis (OR=2.6, P=0.02) were independently associated with GPA, in contrast to previous reports associating eosinophils and necrosis with the diagnosis. Conclusions Neutrophil, eosinophil and macrophage infiltration of orbital tissues, together with vasculitis and necrosis, are all associated with a clinical diagnosis of GPA, but only neutrophil

    Background: Skin infections caused by coryneform bacteria are common dermatological conditions. However, to the best of our knowledge, no studies are available on the clinical characteristics and epidemiological features of this group of disorders as one entity from India and abroad. Aims: To study the clinical and epidemiological features of coryneform skin infections Methods: A total of 75 patients presenting with clinically distinctive lesions of pitted keratolysis, erythrasma and trichobacteriosis to our hospital were included in the study. Cases were interviewed with particular emphasis on epidemiological features and the various clinical findings were recorded. Investigations like Gram's stain, Wood's light examination, 10% KOH scrapings, were done in selected cases to ascertain the diagnosis. Results: Pitted keratolysis was more common in the age group of 31-40 years (40%) with a male preponderance (76.7%), most commonly affecting pressure bearing areas of the soles with malodour (86.7%) and frequent contact with water (58.3%) constituting the most important presenting symptom and provocating factor respectively. Erythrasma affected both male and female patients equally and was more commonly detected in patients with a BMI > 23kg/m2 (62.5%) and in diabetics (50%). All patients with trichobacteriosis presented with yellow coloured concretions in the axillae. Bromhidrosis (71.4%) and failure to regularly use an axillary deodorant (71.4%) were the most common presenting symptom and predisposing factor respectively. Conclusion: Coryneform skin infections are common dermatological conditions, though epidemiological data are fragmentary. Hyperhidrosis is a common predisposing factor to all three coryneform skin infections. Asymmetrical distribution of pits has been reported in our study. Diabetic status needs to be evaluated in all patients with erythrasma. Woods lamp examination forms an indispensible tool to diagnose erythrasma and trichobacteriosis. PMID

    Background: Uterine lipoleiomyoma is a rare and specific type of leiomyoma with a considerable amount of adipocytes. Aims: The aim of the study was to investigate the clinical, pathological and immunohistochemical features of lipoleiomyoma of the uterine corpus, and review its histogenesis and differential diagnosis from other neoplastic and non-neoplastic lesions in order to obtain a detailed profile of this somewhat uncommon lesion. Study Design: Descriptive study. Methods: This study is a retrospective analysis of 70 consecutive women with 76 lipoleiomyomas, who underwent surgery mainly for uterine leiomyoma and gynecological carcinomas between January 2000 and April 2013. Clinical and pathological information was obtained from medical records. Immunohistochemistry was applied in selected cases. Parametric methods were used to compare clinical and pathologic features. Results: The patients ranged in age from 34 to 77 years (mean 55.49 years). Lipoleiomyomas ranged from 0.5 to 55 cm in diameter (mean 5.50 cm). Typical macroscopic and microscopic features were noted. Sixty-nine (90.7%) tumors were in the uterine corpus and five (6.5%) were in the cervix. One broad ligament tumor and one retroperitoneal tumor were also studied. No tumors displayed cytologic atypia, mitosis, necrosis, calcification, or other degenerative changes. Immunohistochemically, the adipose tissue element was positive for vimentin, desmin, S100 protein, estrogen (ER), progesterone (PR), and Ki-67. Among patients with lipoleiomyomas, 53 cases (75.7%) had different types of lesions associated with hyperestrogenic status, such as adenomyosis, endometriosis, endometrial hyperplasia, and polyps, complex atypical endometrial hyperplasia, and gynecologic carcinomas. The follow-up period ranged from one to eight years (mean 4.6 years). There were no recurrences or tumor-related fatalities. Conclusion: In the present study, the lipoleiomyomas were seen more frequently in patients with adenomyosis

    Summary Background When standard therapies fail, clinical trials provide experimental treatment opportunities for patients with drug-resistant illnesses or terminal diseases. Clinical Trials can also provide free treatment and education for individuals who otherwise may not have access to such care. To find relevant clinical trials, patients often search online; however, they often encounter a significant barrier due to the large number of trials and in-effective indexing methods for reducing the trial search space. Objectives This study explores the feasibility of feature-based indexing, clustering, and search of clinical trials and informs designs to automate these processes. Methods We decomposed 80 randomly selected stage III breast cancer clinical trials into a vector of eligibility features, which were organized into a hierarchy. We clustered trials based on their eligibility feature similarities. In a simulated search process, manually selected features were used to generate specific eligibility questions to filter trials iteratively. Results We extracted 1,437 distinct eligibility features and achieved an inter-rater agreement of 0.73 for feature extraction for 37 frequent features occurring in more than 20 trials. Using all the 1,437 features we stratified the 80 trials into six clusters containing trials recruiting similar patients by patient-characteristic features, five clusters by disease-characteristic features, and two clusters by mixed features. Most of the features were mapped to one or more Unified Medical Language System (UMLS) concepts, demonstrating the utility of named entity recognition prior to mapping with the UMLS for automatic feature extraction. Conclusions It is feasible to develop feature-based indexing and clustering methods for clinical trials to identify trials with similar target populations and to improve trial search efficiency.

    Primary meningeal gliomas are rare tumors composed of a heterogeneous group of neoplasms. We present 2 clinically aggressive cases of primary meningeal pleomorphic xanthoastrocytoma that clinically mimicked meningioma. One case presented in the posterior fossa of a 56-year-old woman; the other centered on the left operculum of a 35-year-old woman. These cases showed many of the classic features of pleomorphic xanthoastrocytoma, except that xanthomatous cells were rare and eosinophilic granular bodies were inconspicuous. Both cases exhibited high proliferative indices and superficially invaded the brain. One case harboring a BRAFV600E mutation disseminated to the thecal sac and showed a clinical response to the targeted BRAF inhibitor dabrafenib. These cases seem to represent an unusual primarily extra-axial presentation of pleomorphic xanthoastrocytoma and may account for at least some of the previously reported cases of primary meningeal glioma and/or glial fibrillary acidic protein–immunoreactive meningioma variants. We suggest that BRAF mutation analysis be considered in all meningeal lesions showing atypical histologic or immunohistochemical profiles, particularly those exhibiting glial differentiation, as a diagnostic aid and possible indication for targeted therapy.

    Childhood ataxia is characterized by impaired balance and coordination primarily due to cerebellar dysfunction. Friedreich ataxia, a form of childhood ataxia, is the most common multisystem autosomal recessive disease. Most of these patients are homozygous for the GAA repeat expansion located on the first intron of the frataxin gene on chromosome 9. Mutations in the frataxin gene impair mitochondrial function, increase reactive oxygen species, and trigger redistribution of iron in the mitochondria and cytosol. Targeted therapies for Friedreich ataxia are undergoing testing. In addition, a centralized database, patient registry, and natural history study have been launched to support clinical trials in Friedreich ataxia. The 2011 Neurobiology of Disease in Children symposium, held in conjunction with the 40th annual Child Neurology Society meeting, aimed to (1) describe clinical features surrounding Friedreich ataxia, including cardiomyopathy and genetics; (2) discuss recent advances in the understanding of the pathogenesis of Friedreich ataxia and developments of clinical trials; (3) review new investigations of characteristic symptoms; (4) establish clinical and biochemical overlaps in neurodegenerative diseases and possible directions for future basic, translational, and clinical studies.

    The family of an "affected" subject with limb girdle dystrophy has been studied in order to assess the clinical-hereditary characteristics of the disease and to contribute to its definite genetic features (phenotypical expressiveness of the pathologic gene). The diagnosis of certitude was based on the anamnestic-clinical criteria and instrumental investigations, supported by histological and histochemical studies of the muscles. The clinical, electromyographic and biochemical data made it possible to distinguish the "affected" from the "subclinical" and the healthy subjects. The subjects that, without noticeable symptoms of neuromuscular disorders, showed a slight clinical expressiveness which didn't alter the normal social and working activities, have been defined "subclinical". The modalities of hereditary transmission of this form of muscular dystrophy are considered in the light of the genetics most present trends that are tending to overcome the dominant-recessive dualism. The possibility of a modality of transmission definable as "intermediate inheritance" is proposed. In the case of the examined family the hypothesis that a pathologic recessive autosomic gene gives rise to a clinical expressiveness in heterozygote subjects seems tenable. This situation definable as "incomplete recessive" is rarely found in the limb girdle dystrophy.

    BACKGROUND Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by sporadic, paroxysmal attacks of fever and serosal inflammation. Although the disease usually begins before the age of 20 years, we aimed to evaluate the demography, clinical features and treatment outcome of familial Mediterranean fever in Iranian adult patients above 20 years old. METHODS In this cross-sectional study, adult patients (first attack at the age of >20 years) with a diagnosis of FMF who referred to the gastroenterology and rheumatology Clinics of Ardebil University of Medical Science (situated in north west of Iran) over the period of 2004-2009 were enrolled. FMF diagnosis was based on clinical criteria. RESULTS Forty four FMF patients (30 male and 14 female) with the mean [± Standard Deviation (SD)] age of first attack of 29 ± 7.8 years were enrolled. Abdominal pain (95.5%) and fever (91%) were the most common clinical findings. All of the patients had satisfactorily responded to therapy. Response was complete in 76.7% and partial in 23.3% of the patients. There was no clinical or laboratory evidence of amyloidosis at the time of diagnosis or during follow-up. CONCLUSION Our findings demonstrated that adult-onset FMF in Iran has different characteristics (more common in males, lesser prevalence of arthritis and erysipelas-like erythema, less delay in diagnosis) and treatment outcome (favorable response even to low-dose colchicine) in comparison with the previous data on early onset patients.

    Objective Dysphagia develops with low frequency in patients with dermatomyositis. Our objective was to determine the clinical and laboratory features that can estimate the development of dysphagia in dermatomyositis. Methods This study included 92 Japanese patients with adult-onset dermatomyositis. The associations between dysphagia and clinical and laboratory features including disease-specific autoantibodies determined by immunoprecipitation assays were analyzed. Results Videofluoroscopy swallow study (VFSS) was performed for all patients with clinical dysphagia (n = 13, 14.1%) but not for patients without clinical dysphagia. Typical findings of dysphagia (pharyngeal pooling, n = 11 and/or nasal regurgitation, n = 4) was detected by VFSS in all patients with clinical dysphagia. Eleven patients with dysphagia (84.6%) had anti-transcription intermediary factor 1γ (TIF-1γ) antibody. By univariate analysis, the average age and the male to female ratio, internal malignancy, and anti-TIF-1γ antibody were significantly higher and the frequency of interstitial lung diseases and manual muscle testing (MMT) scores of sternomastoid and dertoid muscles were significantly lower in patients with dysphagia than in patients without dysphagia. Among patients with anti-TIF-1γ antibody, the mean age, the ratios of male to female and internal malignancy were significantly higher and mean MMT scores of sternomastoid muscle were significantly lower in patients with dysphagia compared with patients without dysphagia. By multivariable analysis, the risk of dysphagia was strongly associated with the existence of internal malignancy and ant-TIF-1γ antibody and was also associated with reduced scores of manual muscle test of sternomastoid muscle. Dysphagia was markedly improved after the treatment against myositis in all 13 patients. Conclusion These findings indicate that dysphagia can develop frequently in patients with internal malignancy, anti-TIF-1γ antibody, or severe muscle

    To determine the approximate incidence and clinical features of pernicious anemia in a Korean population, we retrospectively analyzed clinical data for patients with pernicious anemia who were diagnosed between 1995 and 2010 at five hospitals in Chungnam province. Ninety-seven patients were enrolled, who accounted for 24% of patients with vitamin B(12) deficiency anemia. The approximate annual incidence of pernicious anemia was 0.3 per 100,000. The median age was 66 (range, 32-98) yr, and the male/female ratio was 1.25. Anemia-associated discomfort was the most common symptom (79.4%), followed by gastrointestinal and neurological symptoms (78.4% and 38.1%, respectively). Pancytopenia was found in 36 patients (37.1%), and autoimmune disorders were found in 15 patients (15.5%). Antibody to intrinsic factor was detected in 62 (77.5%) of 80 patients examined, and antibody to parietal cells was detected in 35 (43.2%) of 81 patients examined. Of the 34 patients who underwent tests for Helicobacter pylori, 7 (12.5%) were positive. The anemia-associated and gastrointestinal symptoms resolved completely in all patients after intramuscular injection of cobalamin, whereas neurological symptoms remained in some. In conclusion, pernicious anemia is less frequent in Koreans than in Western populations; however, the clinical features of this disorder in Koreans do not differ from those of Western cases.

    Systemic Lupus Erythematosus (SLE) is an autoimmune disease with a very varied spectrum of clinical manifestations that could be partly determined by genetic factors. We aimed to determine the relationship between prevalence of 11 clinical features and age of disease onset with European population genetic substructure. Data from 1413 patients of European ancestry recruited in nine countries was tested for association with genotypes of top ancestry informative markers. This analysis was done with logistic regression between phenotypes and genotypes or principal components extracted from them. We used a genetic additive model and adjusted for gender and disease duration. Three clinical features showed association with ancestry informative markers: autoantibody production defined as immunologic disorder (P = 6.8×10(-4)), oral ulcers (P = 6.9×10(-4)) and photosensitivity (P = 0.002). Immunologic disorder was associated with genotypes more common in Southern European ancestries, whereas the opposite trend was observed for photosensitivity. Oral ulcers were specifically more common in patients of Spanish and Portuguese self-reported ancestry. These results should be taken into account in future research and suggest new hypotheses and possible underlying mechanisms to be investigated. A first hypothesis linking photosensitivity with variation in skin pigmentation is suggested. PMID:22194982

    CHARGE syndrome is a dominant disorder characterized by ocular colobomata, heart defects, choanal atresia, retardation of growth and development, genital hypoplasia, and ear abnormalities including deafness and vestibular disorders. The majority of individuals with CHARGE have pathogenic variants in the gene encoding CHD7, a chromatin remodeling protein. Here, we present a 15-year-old girl with clinical features of CHARGE syndrome and a de novo 6.5 Mb gain of genomic material at 2p25.3-p25.2. The duplicated region contained 24 genes, including the early and broadly expressed transcription factor gene SOX11. Analysis of 28 other patients with CHARGE showed no SOX11 copy number changes or pathogenic sequence variants. To our knowledge, this child's chromosomal abnormality is unique and represents the first co-occurrence of duplication 2p25 and clinical features of CHARGE syndrome. We compare our patient's phenotype to ten previously published patients with isolated terminal duplication 2p, and elaborate on the clinical diagnosis of CHARGE in the context of atypical genetic findings.

    Clinical features and outcome of 2009 H1N1 influenza virus in the paediatric setting is ill-defined. The epidemiologic and clinical features of children with confirmed H1N1 influenza virus infection admitted to an Italian tertiary paediatric hospital from August through December 2009 were evaluated. A total of 63 children (mean age 4.3 years) were studied; of these, 29 (46%) had chronic underlying diseases. The most frequent symptoms and signs at admission were fever (97%), cough (60%) and respiratory disturbances (24%). Forty patients (63.5%) had H1N1-related complications: 32 (51%) pulmonary diseases, three (5%) neurological disorders, such as acute encephalitis or acute disseminated encephalomyelitis, and two (3%) haematological alterations. Three patients were admitted to the Intensive Care Unit. Most children (81%) were treated with oseltamivir: one developed rash during treatment; no other adverse events were noticed. All children survived without sequelae. In conclusions, 2009 H1N1 influenza virus infection in children is associated with a wide spectrum of clinical manifestations. Neurological disorders are not exceptional complications. Oseltamivir therapy seems safe also in infants. PMID:20652313

    Background Individuals with COPD and asthma are an important but poorly characterized group. The genetic determinants of COPD-asthma overlap have not been studied. Objective Identify clinical features and genetic risk factors for COPD-asthma overlap. Methods Subjects were current or former smoking non-Hispanic whites (NHW) or African-Americans (AA) with COPD. Overlap subjects reported a history of physician-diagnosed asthma before the age of 40. We compared clinical and radiographic features between COPD and overlap subjects. We performed genome-wide association studies (GWAS) in the NHW and AA populations, and combined these results in a meta-analysis. Results More women and African Americans reported a history of asthma. Overlap subjects had more severe and more frequent respiratory exacerbations, less emphysema, and greater airway wall thickness compared to subjects with COPD alone. The NHW GWAS identified SNPs in CSMD1 (rs11779254, P=1.57×10−6) and SOX5(rs59569785, P=1.61×10−6) and the meta-analysis identified SNPs in the gene GPR65 (rs6574978, P=1.18×10−7) associated with COPD-asthma overlap. Conclusions Overlap subjects have more exacerbations, less emphysema and more airway disease for any degree of lung function impairment compared to COPD alone. We identified novel genetic variants associated with this syndrome. COPD-asthma overlap is an important syndrome and may require distinct clinical management. PMID:24876173

The median age (range) of studied subjects was 16 years (6 months to 62 years) and the ratio of adults to children was 1.6:1. Forty-eight percent of subjects were 16-30 years old. The common signs, symptoms and clinical features were: nausea/vomiting (74.0%), a positive tourniquet test (73.0%), anorexia (67.0%), hemoconcentration (58.0%), headache (54.0%), abdominal tenderness (43.0%), myalgia (39.0%) and pleural effusion (20.0%). Children had anorexia, a positive tourniquet test, abdominal tenderness and a convalescent rash more frequently than adults. Children also had significantly more prominent plasma leakage as shown by lower serum albumin and sodium and a higher prevalence of pleural effusion, ascites and shock. Although not statistically significant, the prevalence of bleeding in children was higher than in adults but more adults needed blood transfusion. This study provides additional insight into the clinical picture of DHF/DSS in adults and children and may be beneficial for clinicians caring for these adults and children.

    Purpose The aim of this study was to ascertain the clinical characteristics of drug-induced sleep-related eating disorder (SRED). Patients and methods We retrospectively reviewed the medical records of 30 patients with primary SRED (without any comorbid sleep disorders and who were not taking any possible causative medications), and ten patients with drug-induced SRED (occurrence of SRED episodes after starting nightly medication of sedative drugs, which completely resolved after dose reduction or discontinuation of the sedatives). Results All patients with drug-induced SRED took multiple types of sedatives, such as benzodiazepines or benzodiazepine receptor agonists. Clinical features of drug-induced SRED compared with primary SRED were as follows: higher mean age of onset (40 years old in drug-induced SRED vs 26 years old in primary SRED), significantly higher rate of patients who had total amnesia during most of their SRED episodes (75.0% vs 31.8%), significantly lower rate of comorbidity of night eating syndrome (0% vs 63.3%), and significantly lower rate of history of sleepwalking (10.0% vs 46.7%). Increased doses of benzodiazepine receptor agonists may be responsible for drug-induced SRED. Conclusion The clinical features of drug-induced SRED were different from those of primary SRED, possibly reflecting differences in the underlying mechanisms between these two categories of SREDs.

    Purpose To determine risk factors and clinical signs that may differentiate between bacterial, fungal, and acanthamoeba keratitis among patients presenting with presumed infectious keratitis. Design Hospital-based cross-sectional study. Methods We examined the medical records of 115 patients with laboratory-proven bacterial keratitis, 115 patients with laboratory-proven fungal keratitis, and 115 patients with laboratory-proven acanthamoeba keratitis seen at Aravind Eye Hospital, Madurai, India, from 2006–2011. Risk factors and clinical features of the three organisms were compared using multinomial logistic regression. Results Of 95 patients with bacterial keratitis, 103 patients with fungal keratitis, and 93 patients with acanthamoeba keratitis who had medical records available for review, 287 (99%) did not wear contact lenses. Differentiating features were more common for acanthamoeba keratitis than for bacterial or fungal keratitis. Compared to patients with bacterial or fungal keratitis, patients with acanthamoeba keratitis were more likely to be younger and to have a longer duration of symptoms, and to have a ring infiltrate or disease confined to the epithelium. Conclusions Risk factors and clinical examination findings can be useful for differentiating acanthamoeba keratitis from bacterial and fungal keratitis. PMID:24200232

    Objective: To test the hypothesis that core and suggestive features in possible dementia with Lewy bodies (DLB) would vary in their ability to predict an abnormal dopamine transporter scan and therefore a follow-up diagnosis of probable DLB. A further objective was to assess the evolution of core and suggestive features in patients with possible DLB over time depending on the 123I-FP-CIT SPECT scan result. Methods: A total of 187 patients with possible DLB (dementia plus one core or one suggestive feature) were randomized to have dopamine transporter imaging or to follow-up without scan. DLB features were compared at baseline and at 6-month follow-up according to imaging results and follow-up diagnosis. Results: For the whole cohort, the baseline frequency of parkinsonism was 30%, fluctuations 29%, visual hallucinations 24%, and REM sleep behavior disorder 17%. Clinician-rated presence of parkinsonism at baseline was significantly (p = 0.001) more frequent and Unified Parkinson’s Disease Rating Scale (UPDRS) score at baseline was significantly higher (p = 0.02) in patients with abnormal imaging. There was a significant increase in UPDRS score in the abnormal scan group over time (p < 0.01). There was relatively little evolution of the rest of the DLB features regardless of the imaging result. Conclusions: In patients with possible DLB, apart from UPDRS score, there was no difference in the evolution of DLB clinical features over 6 months between cases with normal and abnormal imaging. Only parkinsonism and dopamine transporter imaging helped to differentiate DLB from non-DLB dementia. PMID:27511183

    1994-10-01

    We present five patients with urinary matrix calculi, which, in contrast to the normally brittle calcigerous calculi, are soft, pliable, and amorphous. Common clinical features include a history of calcigerous stone disease, renal surgery, urinary obstruction or stasis, and chronic infection with Proteus species or coliforms. The diagnosis is usually made at surgery, but certain preoperative radiographic findings may be suggestive. Matrix calculi are radiolucent on plain abdominal films, although their appearance on nonenhanced CT scans is similar to that of calcigerous calculi despite their small mineral content. Extracorporeal shockwave lithotripsy is ineffective; open or percutaneous techniques are necessary. Histologic inspection reveals laminar concentric rings of organized matrix with an orderly, layered deposition of minerals. Histochemical investigation can provide insight into the possible sequence of events in normal calculogenesis. The successful management of urinary matrix calculi depends on a high index of suspicion and a thorough knowledge of their clinicopathologic features.

    Bietti’s crystalline dystrophy (BCD) is a rare disease presenting with the appearance of intraretinal crystalline deposits and varying degrees of chorioretinal atrophy commencing at the posterior pole. Within time, intraretinal crystals gradually disappear and chorioretinal atrophy extends beyond the macula even resulting in complete chorioretinal atrophy. Concomitant corneal crystals can be noted in 1/2 - 1/3 of the patients, and the presence of corneal crystals is not a must for establishing the diagnosis. For the past decade, genetic evaluations and newer imaging modalities expand our knowledge about the disease. CYP4V2 gene is found to be the gene responsible for the disease process and new mutations are still being described. Modern imaging modalities, such as a spectral domain optical coherence tomography (SD-OCT) shed light on the anatomic features of the disease. By this, we reiterate the rare and unusual clinical features of BCD. PMID:25738160

    The Hermansky-Pudlak Syndrome (HPS) is a rare, autosomal recessive condition comprising nine genetically heterogeneous entities that feature oculocutaneous albinism (OCA) and bleeding tendency as their principal clinical manifestations. The pathogenesis of HPS involves disturbances in the biogenesis and trafficking of lysosome-related organelles. While the ophthalmologist is trained to address the ocular manifestations of OCA, it is critical for the provider to consider HPS when examining OCA patients as its systemic sequelae may be associated with morbidity and mortality. If there is suspicion of HPS in a patient with albinism, the ophthalmologist should enlist the aid of consultants to confirm the diagnosis and monitor for systemic features. As the nine HPS subtypes explored in this article vary widely in the character and severity of their associated systemic manifestations, some authors advocate determining the specific gene defect in each HPS patient in order to optimize care and provide anticipatory guidance.

    Abstract Purpose: To evaluate the imaging features of anorectal gastrointestinal stromal tumors (GISTs) with clinical and histopathologic correlation. Materials and methods: In this Institutional Review Board-approved, Health Insurance Portability and Accountability Act-compliant retrospective study, 16 patients (12 men; mean age 66 years (30–89 years)) with pathologically proven anorectal GISTs seen at our institution from January 2001 to July 2011 were identified. Electronic medical records were reviewed to obtain clinical data. Pretreatment imaging studies (computed tomography (CT) in 16 patients, magnetic resonance imaging (MRI) in 9 patients and fluorodeoxyglucose (FDG)-positron emission tomography (PET)/CT in 8 patients) were evaluated by 2 radiologists until consensus. The location, size and imaging features of the primary tumor and metastases at presentation, if any, were recorded, and correlated with clinical data and pathologic features (histologic type, presence of necrosis, mitotic activity, risk category, immunohistochemical profile). Results: The mean tumor size was 6.9 × 6.0 cm. Of the 16 tumors, 11 (68.7%) were infralevator, 4 (25%) supra and infralevator and 1 (6.3%) supralevator; 9 (56.2%) were exophytic, 6 (37.5%) both exophytic and intraluminal, and 1 (6.3%) was intraluminal. The tumors were iso- to minimally hypoattenuating to muscle on CT, iso- to minimally hypointense on T1-weighted images, hyperintense on T2-weighted images and showed variable enhancement. Necrosis was seen in 4 (25%), and hemorrhage and calcification in 2 (12.5%) patients each. The tumors were FDG avid with a mean maximum standardized uptake value of 11 (8.4–16.8). All tumors were positive for KIT and CD34. Distant metastasis to liver was seen in 1 patient (6.3%) at presentation. Conclusion: Anorectal GISTs are well-circumscribed, non-circumferential, predominantly infralevator, intramural or exophytic, FDG-avid, hypoattenuating masses, and present without

    Ammonia is commonly used in industry and agriculture. It is also one of the most frequently accidentally spilled chemicals. Exposure to ammonia can cause severe cutaneous burn or freezing injury, ocular injury, and inhalation injury, among them inhalation injury is the most lethal one. Although the diagnosis and treatment of ammonia burns have been improved, the long-term prognosis is not satisfactory. In this article, we reviewed the literature concerning ammonia burns, in order to summarize the clinical features and treatment of such injury.

    Carcinoma ex pleomorphic adenoma poses a challenge to diagnosis and treatment. Herein we describe an extremely unusual case, which presented initially as an intracapsular carcinoma ex pleomorphic adenoma in the right parotid gland. The first recurrence, after an interval of 8 years, showed only recurrence of the benign component. Five years later, a myoepithelial carcinoma arose from the same site. No ductal carcinoma as seen in the initial intracapsular carcinoma ex pleomorphic adenoma was identified. This case report elucidates the atypical clinical behaviour and interesting histological features encountered within this group of salivary neoplasm.

    2010-06-01

    The incidence of adrenocortical tumors (ACTs) is increased in several familial cancer syndromes resulting from abnormalities in genes that encode transcription factors implicated in cell proliferation, differentiation, senescence, apoptosis, and genomic instability. These include P53, MEN1, APC, and PRKAR1A. Adenomas are the most common ACTs, but adrenocortical carcinomas occur rarely as well. The clinical manifestations of ACTs, which result from increased secretion of adrenocortical hormones, are similar in the familial and sporadic forms of the disease. However, their management may differ because of unique aspects of the constitutional syndromes. The analysis of gene expression profiles of ACTs in these constitutional syndromes have contributed to our understanding of adrenal tumorigenesis and revealed new molecular diagnostic and prognostic markers and candidate genes for targeted therapies. This chapter summarizes the clinical and biological features, pathogenesis, and management strategies for ACTs that develop in patients with familial cancer syndrome. PMID:20833338

    Pulmonary artery sarcoma (PAS) is a rare and highly malignant tumor of pulmonary artery origin. Since 1923, when the first case was reported, <300 cases have been reported worldwide. PAS has a poor prognosis, and early diagnosis with radical surgical resection offers patients with PAS the only chance of survival. However, due to its rarity and the non-specificity of its clinical manifestations and imaging presentation, PAS is frequently misdiagnosed as a pulmonary thromboembolic disease, including pulmonary thromboembolism (PTE) and chronic thromboembolic pulmonary hypertension (CTEPH). The present study reports three cases of PAS that were initially misdiagnosed as PTE or CTEPH, and were later shown to be PAS following surgery. In addition, the clinical features of these patients are examined in order to improve the differential diagnosis of PAS during the early stages of the disease, when the prognosis of patients with PAS is at its optimum.

    Abstract Filamentary keratitis (FK) is a chronic and recurrent disorder of the cornea. FK is reportedly associated with various kinds of ocular surface diseases or conditions. Until now, there have been lacks of studies based on quantitative sample analysis concerning FK incidence regularity and inducement characteristics at different ages. This was a retrospective study of 147 patients (162 eyes) with FK who had been continuously and completely recorded from August 2012 to August 2015 at the Second Affiliated Hospital of Zhejiang University in Hangzhou, east of China. Our results suggest that the causative factors of FK varied at different ages and the distribution of filaments on the corneal surface was also diverse with different inducements. By exploring the frequency and clinical features of FK, we believe that the findings from our research will be clinically significant and aid in the early prevention and treatment guidance of the disease.

    Two hundred twenty-one isolates of Acinetobacter baumannii and 15 of Acinetobacter genospecies 3 (AG3) were consecutively collected in a 30-day period during the nationwide project GEIH-Ab2000. Nosocomial acquisition (P = 0.01), intensive care unit admission (P = 0.02), and antibiotic pressure (P = 0.03) were observed to be lower in the AG3 group. AG3 isolates were more frequently implied in wound infections (P = 0.05), while A. baumannii tended to be recovered from respiratory samples (P = 0.08). To our knowledge, this is the first report analyzing the clinical differences among Acinetobacter genospecies, with our findings suggesting that clinical features of AG3 may not be equivalent to those traditionally described for A. baumannii.

    Summary Background Paediatric scalp nevi may represent a source of anxiety for practitioners and parents, as the clinical and dermoscopic features of typical nevi have yet to be defined. Prompted by concern about the large size, irregular borders, and colour variation of scalp nevi, clinicians and parents may request unnecessary excision of these nevi. Objective The purpose of this study is to establish the typical clinical and dermoscopic patterns of scalp nevi in children younger than 18 years old to help optimize clinical care and management. Methods Scalp nevi were imaged with a camera (Canon Rebel, XSi) and dermoscopic attachment (3Gen, Dermlite Foto, 30mm lens) to the camera. The clinical and dermoscopic images were reviewed and analyzed. Both acquired and congenital scalp nevi were included but were not further differentiated from each other. Results We obtained clinical and dermoscopic images of 88 scalp nevi in 39 Caucasian children. Two subjects had received chronic immunosuppressive medication. Nineteen children have had a family history of melanoma. Males (18/39 subjects, 46%) possessed 68% (60 nevi) of scalp nevi imaged. Younger (<10 years old) subjects (24/39 subjects, 62%) possessed 42% (37 nevi) of scalp nevi. The main clinical patterns included eclipse (n=18), cockade (n=3), solid brown (n=42), and solid pink (n=25) nevi. Solid-coloured nevi showed the following dermoscopic patterns: globular (57%), complex (reticular-globular) (27%), reticular (9%), homogenous (6%), and fibrillar (1%). The majority of nevi had a unifying feature—perifollicular hypopigmentation, which caused the appearance of scalloped, irregular borders if occurring on the periphery, or variegation in pigmentation, if occurring within the nevi. Conclusions Older subjects and males tend to harbour a larger proportion of scalp nevi. The main clinical patterns include solid-coloured and eclipse nevi. The most common dermoscopic pattern of scalp nevi is the globular pattern

    Objective To assess the differences in incidence, clinical features, current treatment strategies and outcome in patients with type-2 vs. type-1 acute myocardial infarction (AMI). Methods We included 824 consecutive patients with a diagnosis of type-1 or type-2 AMI. During index hospitalization, clinical features and treatment strategies were collected in detail. At 1-year follow-up, mortality, stroke, non-fatal myocardial infarction and major bleeding were recorded. Results Type-1 AMI was present in 707 (86%) of the cases while 117 (14%) were classified as type-2. Patients with type-2 AMI were more frequently female and had higher co-morbidities such as diabetes, previous non-ST segment elevation acute coronary syndromes, impaired renal function, anaemia, atrial fibrillation and malignancy. However, preserved left ventricular ejection fraction and normal coronary arteries were more frequently seen, an invasive treatment was less common, and anti-platelet medications, statins and beta-blockers were less prescribed in patients with type-2 AMI. At 1-year follow-up, type-2 AMI was associated with a higher crude mortality risk (HR: 1.75, 95% CI: 1.14–2.68; P = 0.001), but this association did not remain significant after multivariable adjustment (P = 0.785). Furthermore, we did not find type-2 AMI to be associated with other clinical outcomes. Conclusions In this real-life population, compared with type-1, type-2 AMI were predominantly women and had more co-morbidities. Invasive treatment strategies and cardioprotective medications were less used in type-2, while the 1-year clinical outcomes were similar. PMID:26918008

    2013-01-01

    Bacterial vaginosis (BV) is a dysbiosis of the vaginal flora characterized by a shift from a Lactobacillus-dominant environment to a polymicrobial mixture including Actinobacteria and Gram-negative bacilli. BV is a common vaginal condition in women and is associated with increased risk of sexually transmitted infection and adverse pregnancy outcomes such as preterm birth. Gardnerella vaginalis is one of the most frequently isolated bacterial species in BV. However, there has been much debate in the literature concerning the contribution of G. vaginalis to the etiology of BV, since it is also present in a significant proportion of healthy women. Here we present a new murine vaginal infection model with a clinical isolate of G. vaginalis. Our data demonstrate that this model displays key features used clinically to diagnose BV, including the presence of sialidase activity and exfoliated epithelial cells with adherent bacteria (reminiscent of clue cells). G. vaginalis was capable of ascending uterine infection, which correlated with the degree of vaginal infection and level of vaginal sialidase activity. The host response to G. vaginalis infection was characterized by robust vaginal epithelial cell exfoliation in the absence of histological inflammation. Our analyses of clinical specimens from women with BV revealed a measureable epithelial exfoliation response compared to women with normal flora, a phenotype that, to our knowledge, is measured here for the first time. The results of this study demonstrate that G. vaginalis is sufficient to cause BV phenotypes and suggest that this organism may contribute to BV etiology and associated complications. This is the first time vaginal infection by a BV associated bacterium in an animal has been shown to parallel the human disease with regard to clinical diagnostic features. Future studies with this model should facilitate investigation of important questions regarding BV etiology, pathogenesis and associated complications

    There are great diversities of clinical phenotypes among the various familial Alzheimer's disease (FAD) families. We aimed to systematically review all the previously reported cases of FAD and to perform comparisons between Asian and white patients. In this regard, we collected individual-level data from 658 pedigrees. We found that patients with presenilin 1 (PSEN1) mutations had the earliest age of onset (AOO; 43.3 ± 8.6 years, p < 0.001) and were more commonly affected by seizures, spastic paraparesis, myoclonus, and cerebellar signs (p < 0.001, p < 0.001, p = 0.003, and p = 0.002, respectively). Patients with PSEN2 mutations have a delayed AOO with longest disease duration and presented more frequently with disorientation (p = 0.03). Patients with amyloid precursor protein (APP) mutations presented more frequently with aggression (p = 0.02) and those with APP duplication presented more frequently with apraxia (p = 0.03). PSEN1 mutations before codon 200 had an earlier AOO than those having mutations after codon 200 (41.4 ± 8.0 years vs. 44.7 ± 8.7 years, p < 0.001). Because 42.9% of the mutations reported are novel, the mutation spectrum and clinical features in Asian FAD families could be different from that of whites. Asian patients with PSEN1 mutations presented more frequently with disorientation (p = 0.02) and personality change (p = 0.01) but less frequently with atypical clinical features. Asian patients with APP mutations presented less frequently with aphasia (p = 0.02). Thus, clinical features could be modified by underlying mutations, and Asian FAD patients may have different clinical features when compared with whites. PMID:26337232

    Spinal muscular atrophy with respiratory distress (SMARD1) is an autosomal recessive neuromuscular disease caused by mutations in the IGHMBP2 gene, encoding the immunoglobulin μ-binding protein 2, leading to motor neuron degeneration. It is a rare and fatal disease with an early onset in infancy in the majority of the cases. The main clinical features are muscular atrophy and diaphragmatic palsy, which requires prompt and permanent supportive ventilation. The human disease is recapitulated in the neuromuscular degeneration (nmd) mouse. No effective treatment is available yet, but novel therapeutical approaches tested on the nmd mouse, such as the use of neurotrophic factors and stem cell therapy, have shown positive effects. Gene therapy demonstrated effectiveness in SMA, being now at the stage of clinical trial in patients and therefore representing a possible treatment for SMARD1 as well. The significant advancement in understanding of both SMARD1 clinical spectrum and molecular mechanisms makes ground for a rapid translation of pre-clinical therapeutic strategies in humans.

    Purpose Identification of high-risk patients with pulmonary embolism is vital. The aim of the present study was to examine clinical scores, their single items, and anamnestic features in their ability to predict 30-day mortality. Materials and Methods A retrospective, single-center study from 06/2005 to 01/2010 was performed. Inclusion criteria were presence of pulmonary embolism, availability of patient records and 30-day follow-up. The following clinical scores were calculated: Acute Physiology and Chronic Health Evaluation II, original and simplified pulmonary embolism severity index, Glasgow Coma Scale, and euroSCORE II. Results In the study group of 365 patients 39 patients (10.7%) died within 30 days due to pulmonary embolism. From all examined scores and parameters the best predictor of 30-day mortality were the Glasgow Coma scale (≤ 10) and parameters of the circulatory system including presence of mechanical ventilation, arterial pH (< 7.335), and systolic blood pressure (< 99 mm Hg). Conclusions Easy to ascertain circulatory parameters have the same or higher prognostic value than the clinical scores that were applied in this study. From all clinical scores studied the Glasgow Coma Scale was the most time- and cost-efficient one. PMID:26866472

    Bacillus cereus is the second most frequent cause of post-traumatic bacterial endophthalmitis. Although genotyping of B. cereus associated with gastrointestinal infections has been reported, little is known about the B. cereus clinical isolates associated with post-traumatic endophthalmitis. This is largely due to the limited number of clinical strains available isolated from infected tissues of patients with post-traumatic endophthalmitis. In this study, we report successful isolation of twenty-four B. cereus strains from individual patients with different disease severity of post-traumatic endophthalmitis. Phylogenetic analysis showed that all strains could be categorized into three genotypes (GTI, GTII and GTIII) and the clinical score showed significant differences among these groups. We then further performed genotyping using the vrrA gene, and evaluated possible correlation of genotype with the clinical features of B. cereus-caused post-traumatic endophthalmitis, and with the prognosis of infection by conducting follow-up with patients for up to 2 months. We found that the disease of onset and final vision acuity were significantly different among the three groups. These results suggested that the vrrA gene may play a significant role in the pathogenesis of endophthalmitis, and genotyping of B. cereus has the potential for predicting clinical manifestation and prognosis of endophthalmitis. To the best of our knowledge, this is the first report of isolation of large numbers of clinical isolates of B. cereus from patients with endophthalmitis. This work sets the foundation for future investigation of the pathogenesis endophthalmitis caused by B. cereus infection.

    Bacillus cereus is the second most frequent cause of post-traumatic bacterial endophthalmitis. Although genotyping of B. cereus associated with gastrointestinal infections has been reported, little is known about the B. cereus clinical isolates associated with post-traumatic endophthalmitis. This is largely due to the limited number of clinical strains available isolated from infected tissues of patients with post-traumatic endophthalmitis. In this study, we report successful isolation of twenty-four B. cereus strains from individual patients with different disease severity of post-traumatic endophthalmitis. Phylogenetic analysis showed that all strains could be categorized into three genotypes (GTI, GTII and GTIII) and the clinical score showed significant differences among these groups. We then further performed genotyping using the vrrA gene, and evaluated possible correlation of genotype with the clinical features of B. cereus–caused post-traumatic endophthalmitis, and with the prognosis of infection by conducting follow-up with patients for up to 2 months. We found that the disease of onset and final vision acuity were significantly different among the three groups. These results suggested that the vrrA gene may play a significant role in the pathogenesis of endophthalmitis, and genotyping of B. cereus has the potential for predicting clinical manifestation and prognosis of endophthalmitis. To the best of our knowledge, this is the first report of isolation of large numbers of clinical isolates of B. cereus from patients with endophthalmitis.

    The receptor tyrosine kinase AXL is a member of the Tyro3-Axl-Mer receptor tyrosine kinase subfamily. AXL affects several cellular functions, including growth and migration. AXL aberration is reportedly a marker for poor prognosis and treatment resistance in various cancers. In this study, we analyzed clinical, pathological, and molecular features of AXL expression in lung adenocarcinomas (LADs). We examined 161 LAD specimens from patients who underwent pulmonary resections. When AXL protein expression was quantified (0, 1+, 2+, 3+) according to immunohistochemical staining intensity, results were 0: 35%; 1+: 20%; 2+: 37%; and 3+: 7% for the 161 samples. AXL expression status did not correlate with clinical features, including smoking status and pathological stage. However, patients whose specimens showed strong AXL expression (3+) had markedly poorer prognoses than other groups (P = 0.0033). Strong AXL expression was also significantly associated with downregulation of E-cadherin (P = 0.025) and CD44 (P = 0.0010). In addition, 9 of 12 specimens with strong AXL expression had driver gene mutations (6 with EGFR, 2 with KRAS, 1 with ALK). In conclusion, we found that strong AXL expression in surgically resected LADs was a predictor of poor prognosis. LADs with strong AXL expression were characterized by mesenchymal status, higher expression of stem-cell-like markers, and frequent driver gene mutations. PMID:27100677

    The authors report the first occurrence to our knowledge of a familial deletion of the short arm of chromosome 18 in a mother and daughter. The proband is an 18-year-old female referred for chromosomal analysis because of mental retardation and short stature. She is the only offspring. Her birth weight was 3 pounds 10 ounces (below 5th percentile). As a child, she had delayed milestones. Her IQ is 69 and she is in classes for the educable mentally handicapped. Her height is 145.6 cm and weight 38.7 kg (both below 5th percentile). Physical examination revealed a low nuchal hairline. She has myopia. Chromosome analysis from peripheral blood lymphocytes revealed a 46,XX,del(18)(p11.21) karyotype. Since some of the same clinical features are also seen in the mother including short stature (157 cm), mental retardation, ocular problems like cataracts, exotropia and refractive error, chromosome analysis was performed which showed the same 46,XX,del(18)(p11.21) karyotype. A familial case like this has great implications in genetic counseling. Since the syndrome is not associated with sterility, the recurrence risk for the offspring is 50%. Patients with deletion (18p) syndrome are reported to have findings suggestive of Turner syndrome with varying degrees of mental retardation. We recommend that in patients with such clinical features associated with mental retardation, normal menstrual history and/or fertility, the possibility of deletion (18p) syndrome be considered.

    Objective and methods Dysferlin encoded by DYSF deficiency leads to two main phenotypes, limb girdle muscular dystrophy (LGMD) 2B and Miyoshi myopathy. To reveal in detail the mutational and clinical features of LGMD2B in Japan, we observed 40 Japanese patients in 36 families with LGMD2B in whom dysferlin mutations were confirmed. Results and conclusions Three mutations (c.1566C>G, c.2997G>T and c.4497delT) were relatively more prevalent. The c.2997G>T mutation was associated with late onset, proximal dominant forms of dysferlinopathy, a high probability that muscle weakness started in an upper limb and lower serum creatine kinase (CK) levels. The clinical features of LGMD2B are as follows: (1) onset in the late teens or early adulthood, except patients homozygous for the c.2997G>T mutation; (2) lower limb weakness at onset; (3) distal change of lower limbs on muscle CT at an early stage; (4) impairment of lumbar erector spinal muscles on muscle CT at an early stage; (5) predominant involvement of proximal upper limbs; (6) preservation of function of the hands at late stage; (7) preservation of strength in neck muscles at late stage; (8) lack of facial weakness or dysphagia; (9) avoidance of scoliosis; (10) hyper-Ckaemia; (11) preservation of cardiac function; and (12) a tendency for respiratory function to decline with disease duration. It is important that the late onset phenotype is found with prevalent mutations. PMID:23243261

    Malignant pleural mesothelioma is almost exclusively caused by exposure to asbestos dust. Recent epidemiological studies have suggested that the national incidence of disease may continue to rise until 2020 and that asbestos exposure in the building trade may be replacing shipyard related exposure as the main source of disease. The objective of the study was to determine if the incidence of malignant pleural mesothelioma was rising in the west of Glasgow from 1987-1992 and whether there had been a change in clinical features compared to previous studies from the same population. Case notes identified from coded returns and the local cancer registry were retrospectively examined: 144 cases were identified. This is an increase in incidence of over 50% compared to the previous study but the yearly incidence did not rise over the period studied. The clinical features and survival times have not changed since previous studies: median survival remains 30 weeks. Only three patients were given definitive treatment reflecting the lack of effective therapy. We suggest that the incidence of mesothelioma in the population studied may already have peaked resulting from the decline in the local shipyard industry over 20 years ago. Non-shipyard sources of asbestos exposure may be less important in this area.

    The clinical and epidemiological features of 80 cases of malignant mesothelioma (as proved by examination of biopsy specimens) referred to the clinic at the National Centre for Occupational Health between January 1977 and June 1983 are reviewed. There was a positive history of asbestos exposure in 89% of cases. The mean survival time from diagnosis to death was 8,6 months and from the onset of symptoms to death 13,6 months. Survival time was unaffected by stage of the tumour, treatment, histological features, smoking status, presenting symptoms, presence or absence of effusion and asbestosis, side of the lesion, source of exposure and lag period from first exposure to diagnosis. The duration of survival was significantly affected by age at diagnosis, duration of asbestos exposure and the number, rather than the type, of treatment regimens used. Caution is advocated in interpreting these data since the number of cases was small and the study design was retrospective. A reference group of 546 cases notified over the same period was drawn from the records of the South African Asbestos Tumour Reference Panel. The incompleteness of national mesothelioma incidence data was noted, and an incidence figure of 7,2 per million per year was calculated from the best-available data for South Africa. This figure is an underestimate because not all diagnosed cases are reflected and, more important, significant numbers of cases are never diagnosed. The extent to which the compensation machinery functions is mentioned.

    Although severe fever with thrombocytopenia syndrome (SFTS) was first reported from Japan in 2013, the precise clinical features and the risk factors for SFTS have not been fully investigated in Japan. Ninety-six cases of severe fever with thrombocytopenia syndrome (SFTS) were notified through the national surveillance system between April 2013 and September 2014 in Japan. All cases were from western Japan, and 82 cases (85%) had an onset between April and August. A retrospective observational study of the notified SFTS cases was conducted to identify the clinical features and laboratory findings during the same period. Of 96 notified cases, 49 (51%) were included in this study. Most case-patients were of advanced age (median age 78 years) and were retired or unemployed, or farmers. These case-patients had a history of outdoor activity within 2 weeks before the onset of illness. The median serum C-reactive protein concentration was slightly elevated at admission. Fungal infections such as invasive aspergilosis were found in 10% of these case-patients. Hemophagocytosis was observed in 15 of the 18 case-patients (83%) whose bone marrow samples were available. Fifteen cases were fatal, giving a case-fatality proportion of 31%. The proportion of neurological abnormalities and serum concentrations of lactate dehydrogenase and aspartate aminotransferase were significantly higher in the fatal cases than in the nonfatal cases during hospitalization. Appearance of neurological abnormality may be useful for predicting the prognosis in SFTS patients. PMID:27776187

    Autosomal recessive interleukin-1 receptor-associated kinase (IRAK)-4 and myeloid differentiation factor (MyD)88 deficiencies impair Toll-like receptor (TLR)- and interleukin-1 receptor-mediated immunity. We documented the clinical features and outcome of 48 patients with IRAK-4 deficiency and 12 patients with MyD88 deficiency, from 37 kindreds in 15 countries. The clinical features of IRAK-4 and MyD88 deficiency were indistinguishable. There were no severe viral, parasitic, and fungal diseases, and the range of bacterial infections was narrow. Noninvasive bacterial infections occurred in 52 patients, with a high incidence of infections of the upper respiratory tract and the skin, mostly caused by Pseudomonas aeruginosa and Staphylococcus aureus, respectively. The leading threat was invasive pneumococcal disease, documented in 41 patients (68%) and causing 72 documented invasive infections (52.2%). P. aeruginosa and Staph. aureus documented invasive infections also occurred (16.7% and 16%, respectively, in 25% and 25% of patients). Systemic signs of inflammation were usually weak or delayed. The first invasive infection occurred before the age of 2 years in 53 (88.3%) and in the neonatal period in 19 (32.7%) patients. Multiple or recurrent invasive infections were observed in most survivors (n = 36/50, 72%). PMID:21057262

    Bone and Joint tuberculosis (BJTB) constitutes about 10% of total extra-pulmonary TB cases. Since the BJTB is a paucibacillary condition, there has been no systematic study on the bacterial characterization, especially the epidemiological feature. Here we collected the mycobacterial clinical isolates, analyzed the clinical features and the bacteriological characteristics from 113 BJTB cases reported in China. The mean age of the cases was 40.33 years while most of the patients fell into the 20-29 year age group; local pain was the most common onset symptom of BJTB cases; mean time from symptom onset to BJTB diagnosis was 13.16 months. 31 isolates were defined as drug resistant, including 15 multidrug resistant (MDR) and 2 extensively drug resistant (XDR) isolates according to the drug susceptibility test outcomes; after spoligotyping, 87.6% (99/113) isolates were categorized as Beijing family. In contrast to the isolates from pulmonary tuberculosis patients, here the MIRU-VNTR assay did not find anything significant. A prolonged time span for BJTB diagnosis highlights the requirement of paying further attention to BJTB infection in China. This study provides essential insights into the demographic and microbial characteristics of BJTB cases in China.

    Backgroud Portal hypertension (PHTN) has been reported to afflict 7-18% of patients with Philadelphia-negative myeloproliferative neoplasms (MPNs), with complications of variceal bleeding and ascites. The clinical features and outcomes of these patients are unclear. Patients and Methods In this multi-centre retrospective study, we evaluated the clinical features of 51 patients with MPNs complicated by PHTN. Results The diagnosis of underlying MPN was most frequently polycythemia vera (PV) (39%) and primary myelofibrosis (MF) (35%), followed by post-PV myelofibrosis (18%), essential thrombocythemia (ET) (4%) and post-ET myelofibrosis (4%). Frequency of JAK2 V617F mutation appears as expected in the underlying MPN. Thrombosis within the splanchnic circulation was prevalent in patients with polycythemia compared to other MPNs (76% vs. 26%, p=0.0007). Conclusions PV and MF patients have a higher incidence of PHTN in our population, with thrombosis contributing to PHTN development in PV patients. Patients with splanchnic circulation thrombosis are potential candidates for screening for portal hypertension. These data may be useful for developing screening strategies for early detection of PHTN in patients with MPN. PMID:25027569

    Acute exacerbation (AE) of interstitial lung disease is reported to be developed in not only idiopathic pulmonary fibrosis but also connective tissue disease-associated interstitial pneumonia (CTD-IP). As the significance of AE of CTD-IP has not been so widely recognized, its clinical feature is not fully elucidated. In the present study, we investigated the incidence, clinical features and outcome of AE of CTD-IP. We retrospectively reviewed admitted cases in our department with medical record from 2011 to 2015. Among 155 patients with CTD-IP, 10 (6.5%) cases developed AE (6 rheumatoid arthritis, 2 polymyositis/dermatomyositis, 1 systemic lupus erythematosus, 1 Sjögren syndrome), and one died of AE within 30 days. Median survival time after the onset of AE was 169 days in all 10 patients. The treatment with immunosuppressant just before AE onset might improve the prognosis of AE. The median survival time after the onset of AE was significantly longer in patients showing good response to corticosteroid compared with those with poor response to corticosteroid (805 days and 45 days, respectively) (p <0.05), suggesting that there are some cases in CTD-IP, showing the good response to corticosteroid even when AE was complicated.

    Cardio-facio-cutaneous syndrome (CFC) is one of the RASopathies that bears many clinical features in common with the other syndromes in this group, most notably Noonan syndrome and Costello syndrome. CFC is genetically heterogeneous and caused by gene mutations in the Ras/mitogen-activated protein kinase pathway. The major features of CFC include characteristic craniofacial dysmorphology, congenital heart disease, dermatologic abnormalities, growth retardation, and intellectual disability. It is essential that this condition be differentiated from other RASopathies, as a correct diagnosis is important for appropriate medical management and determining recurrence risk. Children and adults with CFC require multidisciplinary care from specialists, and the need for comprehensive management has been apparent to families and health care professionals caring for affected individuals. To address this need, CFC International, a nonprofit family support organization that provides a forum for information, support, and facilitation of research in basic medical and social issues affecting individuals with CFC, organized a consensus conference. Experts in multiple medical specialties provided clinical management guidelines for pediatricians and other care providers. These guidelines will assist in an accurate diagnosis of individuals with CFC, provide best practice recommendations, and facilitate long-term medical care. PMID:25180280

    The outcome of snakebite is related to the biting species but it is often difficult to identify the biting snake, particularly in community settings. We have developed a clinical scoring system suitable for use in epidemiological surveys, with the main aim of identifying the presumed biting species in those with systemic envenoming who require treatment. The score took into account ten features relating to bites of the five medically important snakes in Sri Lanka, and an algorithm was developed applying different weightings for each feature for different species. A systematically developed artificial data set was used to fine tune the score and to develop criteria for definitive identification. The score was prospectively validated using 134 species-confirmed snakebites. It correctly differentiated the bites caused by the three snakes that commonly cause major clinical problems (Russell's viper (RV), kraits and cobra) from other snakes (hump-nosed viper (HNV) and saw-scaled viper (SSV)) with 80% sensitivity and 100% specificity. For individual species, sensitivity and specificity were, respectively: cobra 76%, 99%; kraits 85%, 99%; and RV 70%, 99%. As anticipated, the score was insensitive in the identification of bites due to HNV and SSV. PMID:16412486

    The aim of this study was to compare clinical symptoms, perceived health status, health resource use and psychosocial features in fibromyalgia (FM) patients at different health care levels. A total of 315 participants were recruited from primary care (PC) (n=101) and rheumatology settings (RS) (n=214). Subjects completed a protocol of clinical features and health resource use, hospital anxiety and depression scale, sickness impact profile, chronic pain self-efficacy scale, multidimensional pain locus of control scale, perceived health competence scale and chronic pain coping inventory. Student's t test, effect size, and contrast and power test were performed to examine differences between samples. FM patients treated in PC and RS were similar in most variables assessed and only differed significantly in tender points, sleep disturbance, wellness-focused coping strategies and in self-efficacy beliefs. The similarities do not support patient selection through care levels and thus, in the Spanish health care system at least, endorse PC as a reference unit for treatment and questioning the benefits of referring patients to RS.

    Heterozygous loss-of-function (LOF) SMAD4 mutations are associated with juvenile polyposis syndrome (JP) and hereditary hemorrhagic telangiectasia (HHT). Some carriers exhibit symptoms of both conditions, leading to the name JP-HHT syndrome. Three families have been reported with connective tissue abnormalities. In order to better understand the spectrum and extent of clinical findings in SMAD4 carriers, medical records of 34 patients (20 families) from five clinical practices were reviewed. Twenty-one percent (7/34) had features suggesting a connective tissue defect: enlarged aortic root (n=3), aortic and mitral insufficiency (n=2), aortic dissection (n=1), retinal detachment (n=1), brain aneurysms (n=1), lax skin and joints (n=1). JP-specific findings were almost uniformly present but variable. Ninety-seven percent had colon polyps that were generally pan-colonic and of variable histology and number. Forty-eight percent (15/31) had extensive gastric polyposis. HHT features were documented in 76% including epistaxis (19/31, 61%), mucocutaneous telangiectases (15/31, 48%), liver arteriovenous malformation (AVM) (6/16, 38%), brain AVM (1/26, 4%), pulmonary AVM (9/17, 53%), and intrapulmonary shunting (14/23, 61%). SMAD4 carriers should be managed for JP and HHT, since symptoms of both are likely yet unpredictable. Connective tissue abnormalities are an emerging component of JP-HHT syndrome, and larger studies are needed to understand these manifestations. PMID:24525918

    The aim of the present study was to analyze clinical and cytokine features of recurrent respiratory system diseases in children with toxocariasis. 50 children aged 1 to 17 years (mean age - 10±5 years) with recurrent current of respiratory system disorders were studied. During the survey such clinical manifestations of the respiratory system disorders as obstructive bronchitis (50%), bronchial asthma (30%), pneumonia (10%) and laryngotracheitis (10%) have been revealed. Statistical analysis of the results was performed using the software package STATISTICA 6.1 (SNANSOFT). We have shown that the disorders of respiratory system in case of toxocariasis invasion often occur with severe intoxication and bronchial obstruction syndromes, temperature reaction, respiratory insufficiency and hepatomegaly. A prolonged course of the disease has been noted. "Inflammatory" indicators of general blood analysis, such as leukocytosis and increased of ESR have been recorded in patients with respiratory system disorders in children with T.canis infection significantly more often, significant "allergic" laboratory changes were in the form of eosinophilia. High average levels of pro-inflammatory IL-6, as well as low levels of IL 5 have been determined in children suffering from the respiratory system disorders and with toxocariasis invasion in the anamnesis. The obtained findings require further study.

    The aim of this study was to compare and contrast the clinical, immunogenetic and outcome features of two subgroups of Hispanic patients with systemic lupus erythematosus (SLE), one from Northern Spain (Spaniards) and one of from the USA (Hispano-Americans: Hispanics primarily of Mexican ancestry (Amerindian and Spaniard backgrounds). Patients with SLE as per the American College of Rheumatology classification criteria, from two University-affiliated Hospitals (Universidad de Cantabria) and disease of five or less years in duration (n = 28) and with four years of follow up constituted the Spaniard subgroup. Fifty-two patients of Hispano-American ancestry from the LUMINA (Lupus in Minority populations: Nature versus Nurture) cohort constituted the Hispano-American subgroup. Patients were studied using a similar protocol. In short, sociodemographic, clinical, immunological, immunogenetic and psychosocial and behavioral features were obtained at enrollment into the study (baseline visit) and yearly thereafter. The relationship between these variables and disease activity at baseline and over time, as measured by the systemic lupus activity measure (SLAM) and disease damage, as measured by the SLICC (Systemic Lupus International Collaborating Clinics) Damage Index (SDI) were determined. Variables found to be significant at P = 0.10 were then entered into multivariable linear regression models with disease activity at baseline and over time, and damage as the outcome measures. Patients of Hispano-American and Spaniard ethnicity had comparable sociodemographic features except for home density, which was higher among the Hispano-Americans. HLA-DRB1*08 was associated with SLE among the Hispano-Americans but not among the Spaniards. Hispano-American patients had more severe disease as manifested by more frequent clinical manifestations (renal and neurological), higher SLAM scores at baseline and over time and higher SDI scores at the year 4 visit (that despite the fact that

    To assess the incidence, clinical features at presentation, hematologic, immunophenotypic, and cytogenetic characteristics of AMKL in children we prospectively studied 834 consecutive non selected children with newly diagnosed acute leukemia (AL) admitted to the Hematology Department at the Instituto Nacional de Pediatría (INP), Mexico, D.F. We found 682 cases (81.8%) with a typical ALL immunophenotype, and the remaining 152 (18.2%) were considered to have AML. In 29 of the 152 patients with AML studied, a diagnosis of AMKL was established. These 29 cases represented 19.1% of the cases of AML and 3.48% of the total cases of AL during the time span covered by the study. Twenty-four percent of the cases occurred in infants 2 years old or younger and 41.4% occurred in children 41 months of age or younger. In contrast, in only 18.6% of the patients with AML (M0-M6), the diagnosis was established before 42 months of age and in 17% before their second year of life. Clinical presentation was not strikingly different than that observed in patients with other types of AML, and the time interval from onset of symptoms to diagnosis was also similar, though in a small subset of patients, the clinical course was characterized by a chronic slowly progressive disorder extending over weeks or months resembling smoldering leukemia or chronic myelofibrosis with agnogenic myeloid metaplasia. Bone marrow (BM) fibrosis was a constant features in our patients; 75% of the patients studied showed this complication at the time of diagnosis. Some rather unusual findings in this study were intense skeletal pains from multiple osteolytic lesions, the presence of soft-tissue tumor, and the presence of cohesive scanty clusters of primitive-looking blast cells in BM aspirates. Several interesting cytogenetic findings in our study were t(1;22)(p13;q13) in a 14-year-old boy, t(9;22)(q34;q11) in one patient, and monosomy 7 in two patients. Another important finding in our study was the clinical

    This study aimed to determine clinical features of adult patients with gelastic seizures recorded on video -electroencephalography (EEG) over a 5-year period. We screened video-EEG telemetry reports for the occurrence of the term "gelastic" seizures, and assessed the semiology, EEG features, and duration of those seizures. Gelastic seizures were identified in 19 (0.8%) of 2,446 admissions. The presumed epileptogenic zone was in the hypothalamus in one third of the cases, temporal lobe epilepsy was diagnosed in another third, and the remainder of the cases presenting with gelastic seizures were classified as frontal, parietal lobe epilepsy or remained undetermined or were multifocal. Gelastic seizures were embedded in a semiology, with part of the seizure showing features of automotor seizures. A small proportion of patients underwent epilepsy surgery. Outcome of epilepsy surgery was related to the underlying pathology; two patients with hippocampal sclerosis had good outcomes following temporal lobe resection and one of four patients with hypothalamic hamartomas undergoing gamma knife surgery had a good outcome.

    Combined central and peripheral demyelination (CCPD) is rare, and current knowledge is based on case reports and small case series. The aim of our study was to describe the clinical features, diagnostic results, treatment and outcomes in a large cohort of patients with CCPD. Thirty-one patients entered this retrospective, observational, two-center study. In 20 patients (65%) CCPD presented, after an infection, as myeloradiculoneuropathy, encephalopathy, cranial neuropathy, length-dependent peripheral neuropathy, or pseudo-Guillain-Barré syndrome. Demyelinating features of peripheral nerve damage fulfilling European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) electrodiagnostic criteria for CIDP were found in 23 patients (74%), and spatial dissemination of demyelinating lesions on brain MRI fulfilling the 2010 McDonald criteria for multiple sclerosis (MS) in 11 (46%). Two thirds of the patients had a relapsing or progressive disease course, usually related to the appearance of new spinal cord lesions or worsening of the peripheral neuropathy, and showed unsatisfactory responses to high-dose corticosteroids and intravenous immunoglobulins. The clinical presentation of CCPD was severe in 22 patients (71%), who were left significantly disabled. Our data suggest that CCPD has heterogeneous features and shows frequent post-infectious onset, primary peripheral nervous system or central nervous system involvement, a monophasic or chronic disease course, inadequate response to treatments, and a generally poor outcome. We therefore conclude that the current diagnostic criteria for MS and CIDP may not fully encompass the spectrum of possible manifestations of CCPD, whose pathogenesis remains largely unknown.

    Background Mild hand, foot and mouth disease (HFMD) is at a critical stage owing to its ease of communicability and a higher risk of developing severe complications and death. Clinical diagnosis of mild HFMD was made by the presenting symptoms and signs (symptoms in brief) alone. We aim to evaluate the frequencies of symptoms in a retrospective case series study. Methods We collected epidemiological, demographic, clinical, and laboratory data from outpatient and inpatient settings on the clinical data warehouse system. We principally described the frequencies of symptoms of mild HFMD. Correlations between symptoms with laboratory-confirmed cases were then analyzed. Results The clinical data warehouse system included 3649 probable cases, between 2010 and 2012, of which 956 (26.20%) were laboratory confirmed. The peak incidence was identified in children 2 years of age. A total of 370 of the 956 laboratory confirmed cases (38.70%) were associated with enterovirus 71 (EV71). Logistic regression analysis adjusted for geographical variables, age, sex, month of onset, and time from onset to diagnosis showed that the clinical features constipation (P<0.0001; adjusted OR, 95%CI (2.99, 2.28–3.91)), and blisters (P<0.0001; adjusted OR, 95%CI (2.16, 1.82–2.56)) were positively correlated with the confirmed cases. Conclusions This is the largest case series study, including all the guideline-mentioned symptoms of mild HFMD. Our findings suggest that blisters and constipation should be considered as potential warning signs while front-line clinicians manage surges of children diagnosed with mild HFMD during a pandemic.

    2014-01-01

    Background Many studies have shown that clinical characteristics and outcomes differ depending on pathologic variants of focal segmental glomerulosclerosis (FSGS). However, these are not well defined in Asian populations. Methods This retrospective study evaluated clinical features and outcomes of pathologic FSGS variants in 111 adult patients between January 2004 and December 2012. Primary outcome was the composite of doubling of baseline serum creatinine concentrations (D-SCr) or onset of end-stage renal disease (ESRD). Secondary outcome included complete (CR) or partial remission (PR). Results There were 70 (63.1%), 20 (18.0%), 17 (15.3%), 3 (2.7%), and 1 (0.9%) patients with not-otherwise specified (NOS), tip, perihilar, cellular, and collapsing variants, respectively. At presentation, nephrotic-range proteinuria occurred more commonly in tip lesion than in other variants. The overall 5-year renal survival rate was 76.8%. During a median follow-up of 34.5 months, only 1 (5.0%) patient with a tip lesion reached the composite end point compared to 2 (11.8%) and 12 (17.1%) patients in perihilar and NOS variants, but this difference was not statistically significant in an adjusted Cox model. However, tip lesion was associated with a significantly increased probability of achieving CR (P = 0.044). Conclusion Similar to other populations, Korean adult patients with FSGS have distinct clinical features with the exception of a rare frequency of cellular and collapsing variants. Although pathologic variants were not associated with overall outcome, the tip variant exhibited favorable outcome in terms of achieving remission. Further studies are required to delineate long-term outcome and response to treatment of the pathologic variants. PMID:24666814

    Background and Aims To date, few studies have examined the clinical manifestation of disordered gamblers in financial markets. This study examined the differences in the clinical and treatment-related features of gambling disorder between financial markets and horse races. Methods Subjects who met the DSM-IV criteria for pathological gambling (PG) and who sought treatment were assessed by retrospective chart review. One hundred forty-four subjects were included in this sample, which consisted of the following groups: financial markets (n = 45; 28.6%) and horse races (n = 99; 71.4%). Results Multiple similar manifestations were found between the groups, including severity of PG, age of PG onset, amounts of gambling debts, drinking days per week, depressive mood, duration of seeking treatment after the onset of PG, and treatment follow-up duration. However, disordered gamblers who invested in the financial market were significantly more likely to be educated (p = 0.003), live with their spouses (p = 0.007), have full-time jobs (p = 0.006), and they were more likely to participate in the first type of gambling than the horse races group (p<0.001). Furthermore, the financial markets group received the anti-craving medication less often than the horse races group (p = 0.04). Discussion and Conclusions: These findings suggest that disordered gamblers in financial markets show different socio-demographic, clinical and treatment-related features compared with the horse race gamblers, despite a similar severity of gambling disorder. Understanding these differential manifestations may provide insight into prevention and treatment development for specific types of gambling. PMID:26690619

    Abstract The authors aimed to explore whether distinct clinical, serological, and urinalysis findings are associated with specific histological classes of lupus nephritis. Clinical and laboratory features were recorded at the time of clinical diagnosis from 297 consecutive patients with biopsy-confirmed lupus nephritis. Univariate and logistic regression analyses were performed and a risk score was developed to estimate the risk for developing different classes of lupus nephritis. Variables independently associated with class II included absence of malar rash, negative anti-dsDNA, and ≤5 urine leucocytes/high power field (hpf); with III/IV: age at nephritis diagnosis ≤32 years old, presence of musculoskeletal features, new-onset hypertension, positive anti-dsDNA, >5 urine leucocytes/hpf, creatinine >1.2 mg/dL, cellular casts >1/hpf, and absence of nephrotic range proteinuria; with V: age at nephritis diagnosis >32 years, malar rash, absence of musculoskeletal complaints or serum C3 hypocomplementemia, nephrotic range proteinuria, and ≤9 urine erythrocytes/hpf. A risk predictive score of specific histological classes was calculated for each patient. Associations between 2, 3 or more risk factors with specific histological classes were also revealed [Odds ratios (95% confidence interval) (≥2 risk factors) was 6.7 (2.8–17.4) for class II nephritis, 15.6 (5.1–47.8), and 8.2 (3.6–19.0) for classes III/IV and for class V, respectively (≥3 risk factors)]. The identification of independent factors associated with specific classes of lupus nephritis can provide guidance in selecting specific therapeutic modalities, particularly in cases in which renal biopsy is contraindicated.

    Smith-Magenis Syndrome (SMS) frequently goes unrecognized in newborns and infants as these patients do not yet demonstrate the characteristic behavioral phenotype and may only present with developmental delay and physical dysmorphism. Six of Hall`s ten cardinal features of trisomy 21 in the newborn are also frequently found in newborns with SMS, leading to an early presumptive diagnosis of DS in many of these patients. CASE No. 1: Based on clinical findings, a presumptive diagnosis of DS was given to the patient in the newborn period. Chromosome analysis of peripheral blood revealed a normal 46,XX karyotype. Given this result, the possibility of mosaic DS was raised, and a skin fibroblast study done. Again, the karyotype was reported as normal. Clinical features and cytogenetic analysis confirmed a diagnosis of SMS when the patient was 8 years old. CASE No. 2: A presumptive diagnosis of DS was made in an infant with hypotonia, facial dysmorphisms and congenital heart defects. A routine chromosome analysis was ordered, which revealed a 46,XY,del(17)(p11.2p11.2) karyotype. Indeed, approximately 38% of blood samples referred to our laboratory to rule out DS in an infant failed to demonstrate trisomy for chromosome 21. Given the high degree of clinical overlap with Down Syndrome, the diagnosis of SMS should be considered in all such patients. Additional analysis should be done to look for deletion 17p11.2 when faced with a {open_quotes}normal{close_quotes} karyotype in an infant referred to rule out DS.

    Ankylosing spondylitis (AS) is a chronic inflammatory disease, which typically begins in early decades of life with primarily axial joints involvement. This disease rarely affects patients older than 50 years of age. The aim of this study was to compare and evaluate the demographic, clinical, and laboratory features of late onset and early onset AS patients who were followed up in a single rheumatology center. A total of 339 patients who have been diagnosed with AS according to modified New York criteria were included in the study. The patients whose initial symptoms were observed after 50 years of age were accepted as late onset AS. Out of 339 patients, 27 (7.9%) were diagnosed as late onset AS and 312 (92.3%) patients were evaluated as early onset AS. Of 27 late onset patients, 10 were male and 17 were female. Delay in the diagnosis was 5.8 years for early onset AS, while it was 3.8 years for late onset AS (p = 0.001). Higher levels of acute phase reactants and more methotrexate (MTX) use were detected in early onset AS patients compared to late onset AS (p = 0.001, p = 0.007, respectively). Statistically, there was no difference between these two groups, with regard to disease clinical activity indexes, anthropometric measurement parameters, uveitis and peripheral joint involvement. In this study, we showed that early and late onset AS patients may present with different clinical, genetic, and laboratory features. Late onset AS patients are characterized with lower human leukocyte antigen-B27 sequence, less inflammatory sign, delayed diagnosis, and less MTX and anti-tumor necrosis factor alpha drug usage.

    Aggressive/attacking and helpful/emphatic/prosocial behaviors are extremely important in human relationships. Both high levels of aggression and deficits of prosociality play important role in the development and conservation of mental disorders. We review the measurement options and clinical importance of aggressive and prosocial behavior. The typical developmental pathways and the genetic and environmental background of these behaviors are presented. The clinical tools used in the measurement of aggression and prosociality are summarized in the present paper, with specific attention on questionnaires applied in Hungarian practice. The connections between diagnostic categories (conduct disorder, oppositional-defiant disorder, attention deficit and hyperactive disorder, autism spectrum disorders) and the two behaviors are evaluated. In the end, we present those additional research projects that explore the cognitive-emotional background of aggressive or prosocial behavior with clinical relevance either in the diagnosis or in the treatment of child psychiatric diseases.

    Acute kidney injury (AKI) is a clinical syndrome with multiple entities. Although AKI implies renal damage, functional impairment or both, diagnosis is solely based on the functional parameters of serum creatinine and urine output. The latest definition was provided by the Kidney Disease Improving Global Outcomes (KDIGO) working group in 2012. Independent of the underlying disease, and even in the case of full recovery, AKI is associated with an increased morbidity and mortality. Awareness of the patient's individual risk profile and the diversity of causes and clinical features of AKI is pivotal for optimization of prophylaxes, diagnosis and therapy of each form of AKI. A differentiated and individualized approach is required to improve patient mortality, morbidity, long-term kidney function and eventually the quality of life. In this review, we provide an overview of the different clinical settings in which specific forms of AKI may occur and point out possible diagnostic as well as therapeutic approaches. Secifically AKI is discussed in the context of non-kidney organ failure, organ transplantation, sepsis, malignancy and autoimmune disease. PMID:26251707

    Relapsing polychondritis is a rare multisystemic disease widely accepted as a complex autoimmune disorder affecting proteoglycan-rich structures and cartilaginous tissues, especially the auricular pinna, cartilage of the nose, tracheobronchial tree, eyes, and heart's connective components. The clinical spectrum may vary from intermittent inflammatory episodes leading to unesthetic structural deformities to life-threatening cardiopulmonary manifestations, such as airway collapse and valvular regurgitation. The frequent association with other rheumatologic and hematologic disorders has been extensively reported over time, contributing to define its complexity at a diagnostic and also therapeutic level. Diagnosis of relapsing polychondritis is mainly based on clinical clues, while laboratory data have only a supportive contribution. Conversely, radiology is showing a relevant role in estimating the rate of systemic involvement as well as disease activity. The present review is aimed at providing an update on scientific data reported during the last 3 years about relapsing polychondritis in terms of pathogenesis, clinical features, diagnosis, and new treatment options.

    Becker muscular dystrophy (BMD) was first described in 1953 by Emile Becker as a benign variant of Duchenne muscular Dystrophy (DMD). Compared with DMD, BMD is clinically more heterogeneous, with initial presentation in the teenage years and loss of ambulation beyond the age of 16 and a wide spectrum of clinical presentations, ranging from only myalgias and muscle cramps to exercise intolerance and myoglobinuria, asymptomatic elevation of serum creatin-kinase, or mild limb-girdle weakness and quadriceps myopathy. About 50% of patients become symptomatic by the age of 10 and the most part by the age of 20 years. However few patients can be free of symptoms till their fifties and cases of late-onset Becker Muscular Dystrophy have also been described. In this report we describe the clinical features of patients with dystrophinopathy sharing a deletion of exons 45-55, occasionally or retrospectively diagnosed. These data are important for both the prognostic aspects of children presenting this dystrophin gene mutation, and for the genetic counseling in these families (reassuring them on the benign course of the disease), and last but not least to keep in mind a diagnosis of BMD in asymptomatic adults with mild hyperckemia.

    Upper urinary tract urothelial carcinoma (UT-UC) is rare and treatment options or prognostic markers are limited. There is increasing evidence indicating that urothelial carcinoma may be an endocrine-related cancer. The aim of this study was to analyze the prognostic effect of estrogen receptor beta (ERβ) on the outcome of UT-UC. From 2005 to 2012, this study included 105 patients with pT3 UT-UC. Perioperative factors, pathological features, and ERβ immunostaining were reviewed and prognostic effects were examined by multivariate analysis. This study divided patients into either the ERβ-high (n = 52) or ERβ-low (n = 53) group and analyzed their oncologic outcomes. All pathological features except infiltrating tumor architecture (significantly higher incidence in ERβ-low group, p = 0.004) are symmetric in both groups. Low ERβ expression was significantly correlated with local recurrence and distant metastasis in univariate analysis (p = 0.035 and 0.004, respectively) and multivariate analysis (p = 0.05 and 0.008, respectively). Cell line study also proved that knock down of ERβ cause less UTUC proliferation and migration. In addition, ERβ agonist also enhanced the cytotoxic and migration inhibition effect of cisplatin and ERβ antagonist cause the UTUC cell more resistant to cisplatin. This result may help identify patients in need of adjuvant therapy or develop potential targeted therapy. PMID:27052470

    Accurate diagnosis of the cause of aggression in horses is essential to determining the appropriate course of action. The affective forms of aggression include fear-induced, pain-induced, intermale, dominance, protective, maternal, learned, and redirected aggressions. Non-affective aggression includes play and sex-related forms. Irritable aggression and hypertestosteronism in mares are medical problems, whereas genetic factors, brain dysfunction, and self-mutilation are also concerns. PMID:3492250

    Anxiety and depressive problems have often been related to higher hypothalamic-pituitary-adrenal (HPA)-axis activity (basal morning cortisol levels and cortisol awakening response [CAR]) and externalizing problems to lower HPA-axis activity. However, associations appear weaker and more inconsistent than initially assumed. Previous studies from the Tracking Adolescents Individual Lives Study (TRAILS) suggested sex-differences in these relationships and differential associations with specific dimensions of depressive problems in a general population sample of children (10-12 years). Using the TRAILS population sample (n=1604), we tested hypotheses on the association between single day cortisol (basal morning levels and CAR) and specifically constructed dimensions of anxiety (cognitive versus somatic), depressive (cognitive-affective versus somatic), and externalizing problems (reactive versus proactive aggression), and explored the modifying role of sex. Moreover, we repeated analyses in an independent same-aged clinic-referred sample (n=357). Structural Equation Modeling was used to investigate the association between cortisol and higher- and lower-order (thus, broad and specific) problem dimensions based on self-reports in an integrated model. Overall, findings were consistent across the population and clinic-referred samples, as well as with the existing literature. Most support was found for higher cortisol (mainly CAR) in relation to depressive problems. However, in general, associations were weak in both samples. Therefore, the present results shed doubt on the relevance of single day cortisol measurements for problem behaviors in the milder range. Associations may be stronger in more severe or persistent psychopathology. PMID:23237815

    Abstract To investigate the epidemiology, clinical features, and drug-resistance profile of urinary tuberculosis (UTB) in south-western China to improve UTB diagnostics. After the screening of 1036 cases of suspected UTB, 193 patients with UTB were enrolled during 2009 to 2014. Urine samples were collected for routine urinalysis, smear, tuberculosis DNA (TB-DNA) detection, and drug-resistant analysis, whereas blood samples were collected for erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and renal function evaluation. Clinical features (such as symptoms and outcome) and imageology results (such as B ultrasonic, computerized tomography, intravenous pyelography, and renography) were also collected and analyzed to investigate the epidemiology, clinical features, and drug-resistance profile. The most common presenting symptoms were urinary irritation (61.1%) and lumbago (49.2%). High proportions of microscopic hematuria (63.2%) and microscopic proteinuria (45.6%) were also observed. The positive rate for TB-DNA was 66.3%. The positive rate for culture was 13.1% and for smear it was 9.8%. The abnormal outcome rates of the computerized tomography, ultrasonography, intravenous pyelography, and the nephrogram were 76.9%, 70.1%, 29.8%, and 37.0%, respectively. The total rate of drug-resistant TB (resistant to at least 1 drug) was 39.7%, of which 20.7% was multidrug-resistance TB. The most prevalent mutation sites were katG S315T1, rpoB S531L, and gyrA D94G. We observed a serious epidemic of drug-resistant UTB and a substantial number of new UTB cases with multidrug resistance TB. Molecular diagnostics is crucial in the definite diagnosis of UTB, and our finding is a supplement and further confirmation of polymerase chain reaction usage for TB diagnosis. We recommend real-time polymerase chain reaction for TB-DNA identification instead of culture, and GenoType tests (MTBDRplus and MTBDRsl assay) for drug resistance as routine assays for patients with

    Visceral leishmaniasis (VL) is an important health problem in Tunisia. It is most common in children under five years of age. The governorate of Kairouan (central Tunisia) is one of the most affected foci. The aim of this study was to update the epidemiological, clinical and biological features of the disease. The study concerned all VL cases admitted in the pediatric department of Kairouan hospital during 10 years (from 2004 to 2013). For every patient included in this study and when available, data such as sex, age, geographical origin and the condition of the patient at admission (clinical and biological findings) were collected. The myelogram results were also exploited as well as results of serology, culture, Real-Time polymerase chain reaction (PCR) and isoenzymatic typing of Leishmania isolates. Two hundred and forty cases were recorded. Rural cases (87.1%) were more prevalent than urban ones (12.9%). Age ranged from 2 months to 13 years (median, 18 months). The female/male sex ratio was 1.03. The diagnosis delays ranged from 1 day to 8 months (median, 15 days). The most common clinical symptoms at admission were splenomegaly (97.9%), fever (79.9%) and hepatomegaly (47.3%). The principal biological disturbances were anemia (91.7%), thrombocytopenia (83.9%) and leucopenia (56.1%). Among the different biological tools used for diagnosis confirmation, PCR was the most sensitive (100%). All 43 typed stocks corresponded to Leishmania (L.) infantum species. Although zymodeme MON-1 was predictably the most frequent (27 cases), L. infantum MON-24 and MON-80 were responsible of no negligible numbers of cases (11 and 5 cases respectively). The present study gave an updated epidemiological, clinical and biological profile of infantile VL in Tunisia. The diagnosis delays were considerably shortened compared to previous reports. However, an even earlier diagnosis of cases is needed to improve the disease prognosis. Real-Time PCR showed to be helpful in VL management.

    Background Refractory anemia with ring sideroblasts associated with marked thrombocytosis was proposed as a provisional entity in the 2001 World Health Organization classification of myeloid neoplasms and also in the 2008 version, but its existence as a single entity is contested. We wish to define the clinical features of this rare myelodysplastic/myeloproliferative neoplasm and to compare its clinical outcome with that of refractory anemia with ring sideroblasts and essential thrombocythemia. Design and Methods We conducted a collaborative retrospective study across Europe. Our database included 200 patients diagnosed with refractory anemia with ring sideroblasts and marked thrombocytosis. For each of these patients, each patient diagnosed with refractory anemia with ring sideroblasts was matched for age and sex. At the same time, a cohort of 454 patients with essential thrombocythemia was used to compare outcomes of the two diseases. Results In patients with refractory anemia with ring sideroblasts and marked thrombocytosis, depending on the Janus Kinase 2 V617F mutational status (positive or negative) or platelet threshold (over or below 600×109/L), no difference in survival was noted. However, these patients had shorter overall survival and leukemia-free survival with a lower risk of thrombotic complications than did patients with essential thrombocythemia (P<0.001) but better survival (P<0.001) and a higher risk of thrombosis (P=0.039) than patients with refractory anemia with ring sideroblasts. Conclusions The clinical course of refractory anemia with ring sideroblasts and marked thrombocytosis is better than that of refractory anemia with ring sideroblasts and worse than that of essential thrombocythemia. The higher risk of thrombotic events in this disorder suggests that anti-platelet therapy might be considered in this subset of patients. From a clinical point of view, it appears to be important to consider refractory anemia with ring sideroblasts and

    Methicillin-resistant Staphylococcus aureus (MRSA) infection is an important public health issue. This observational study aimed to characterize clinical features, antibiotic susceptibility, and genotypes of ocular infections caused by MRSA based on the clinical and molecular definitions of community-associated (CA) and healthcare-associated (HA) strains.Fifty-nine patients with culture-proven S aureus ocular infection were enrolled from January 1, 2010 to December 31, 2011 at Chang Gung Memorial Hospital, Taiwan. Antibiotic susceptibility was verified using disk diffusion/E test. For characterization, staphylococcal cassette chromosome mec (SCCmec), pulsed-field gel electrophoresis (PFGE), multilocus sequence type (MLST), and Panton-Valentine leukocidin (PVL) gene, were performed. MRSA isolates from the patients with HA factors were classified as clinically defined HA-MRSA, and those carrying SCCmec type I to III as molecularly defined HA-MRSA.Thirty-four patients with MRSA ocular infection were identified. The most common clone of CA-MRSA and HA-MRSA isolates was ST59/PFGE type D/SCCmec IV,VT/PVL (+) (n = 12) and CC 239/PFGE type A/SCCmec III, IIIA/PVL(-) (n = 10), respectively. All the 11 patients with molecularly defined HA-MRSA infections and 50% of the 22 patients with molecularly defined CA-MRSA infections were found to have HA factors (P = .005). CA-MRSA tended to cause lid infections, whereas HA-MRSA tended to cause corneal infections. Contrary to HA-MRSA isolates, nearly all the CA-MRSA isolates were susceptible to trimethoprim/sulfamethoxazole and fluoroquinolones under either clinical or molecular classifications.In Taiwan, CA-MRSA isolates exhibited considerably higher susceptibility to fluoroquinolones when compared with HA-MRSA isolates. A strong correlation was observed between the HA factors and molecularly defined HA-MRSA isolates.

    AIM To describe the clinical features and microstructural characteristics assessed by in vivo confocal microscopy (IVCM) in patients with ocular cicatricial pemphigoid (OCP). METHODS A descriptive, uncontrolled case series study. Patients diagnosed with OCP were examined by clinical history, slit-lamp biomicroscopy features and IVCM images. The results of direct immunofluorescence (DIF) biopsies and indirect immunofluorescence (IIF) were also recorded. Local and systemic immunosuppressive therapy were administered and adjusted according to response. RESULTS A total of 12 consecutive OCP patients (7 male, 5 female; mean age 60.42±10.39y) were recruited. All patients exhibited bilateral progressive conjunctival scarring and recurrent chronic conjunctivitis was the most frequent clinical pattern. The mean duration of symptoms prior to diagnosis of OCP was 2.95±2.85y (range: 5mo to 10y). The Foster classification varied from stage I to IV and 20 eyes (83%) were within or greater than Foster stage III on presentation. Two of the 12 patients (17%) demonstrated positive DIF; 3 of the 12 (25%) patients reported positive IIF. The mean duration of the follow-up period was 20.17±11.88mo (range: 6 to 48mo). IVCM showed variable degrees of abnormality in the conjuctiva-cornea and conjuctival scarring was detected in all the involved eyes. Corneal stromal cell activation and dendritic cell infiltration presented as ocular surface inflammation, ocular surface keratinization along with the destroyed Vogt palisades was noted in eyes with potential limbal stem cell deficiency. After treatment, remission of ocular surface inflammation was achieved in all the patients, 18 eyes (75%) remained stable, 6 eyes (25%) had recurrent conjunctivitis and cicatrization in 2 eyes (8%) was progressing. CONCLUSION As an autoimmune disease, OCP manifests as variable degrees of clinical and laboratory abnormalities with both local and systemic immunosuppressive treatment playing important roles

    The main aetiology of human arsenic toxicity provide from natural geological source. The characteristic skin lesions of arsenic toxicity may be used as an indicator of high exposure. We have registered 45 cases. The age bracket was one to 70 years. We have registered 27 women (60%) and 18 men (40%). The cutaneous manifestations have been dominated by the palmo plantar hyperkeratosis and hyperpigmentations (77,8% each one). The urinary concentrations of arsenic were 13 microg/l to 212 microg/l; they were 69 to 101 microg/l in the drinking water localized in the golden area, however they were normal outside this area. The clinical features were similar with the description of the literature. Intoxication of drinking water is problem of public health and we recommend checking all the other golden areas to find some appropriate solutions.

    Sixteen patients with posttraumatic spinal cord cysts (PTSCC) were evaluated clinically and studied with metrizamide computed tomography (MCT). These patients presented months to years following a severe spinal cord injury, usually with new or progressively worsening neurological symptoms. The development of the PTSCC was unrelated to the location, type, and severity of injury, or to the time interval from the original injury. MCT showed that these cysts occur most frequently in normal or atrophic cords, they may be multiple, they most frequently are found in the dorsal portion of the cord, and they may vary along their length in width and position within the cord. Knowledge of this radiographic morphology is crucial to the surgical planning. The location of the cysts and the mode of their enlargement are correlated with anatomic features of the spinal cord and changes in cerebrospinal fluid dynamics. Cyst-to-subarachnoid space shunting relieves the majority of symptoms.

    Parkinson disease (PD) is a common neurodegenerative disease characterized by classical motor symptoms, including static tremor, bradykinesia, rigidity and postural and gait abnormalities. Besides, recent studies have found a variety of non-motor symptoms, including neuropsychiatric symptoms, sleep disorders, abnormal sensory and autonomic dysfunctions, etc. PD with pure apathy, referring to apathy without dementia and depression, is correlated with motor symptoms and other non-motor symptoms, and greatly reduces the activity of daily living and the quality of life for PD patients. The pathogenesis of PD with pure apathy involves the mechanisms of neuroanatomy, neuropathology, neurological biochemistry and neuroinflammation. This paper will introduce the clinical features and pathogenic mechanisms of PD with pure apathy. PMID:26521484

    Heterotopic ossification (HO) is a benign condition of abnormal formation of bone in soft tissue. HO is frequently asymptomatic, though when it is more severe it typically manifests as decreased range of motion at a nearby joint. HO has been recognized to occur in three distinct contexts-trauma, neurologic injury, and genetic abnormalities. The etiology of HO is incompletely understood. A posited theory is that HO results from the presence of osteoprogenitor cells pathologically induced by an imbalance in local or systemic factors. Individuals at high risk for HO development frequently undergo prophylaxis to prevent HO formation. The two most commonly employed modalities for prophylaxis are nonsteroidal anti-inflammatory drugs and radiation therapy. This review discusses HO pathophysiology, clinical features, and the role of radiotherapy for prophylaxis.

    Twenty patients affected by bilateral occipital cortical-subcortical calcification (BOC) are described, 19 (95%) had epilepsy. In 8 of 16 cases studied, intestinal biopsy revealed coeliac disease. Fourteen patients had occipital partial epilepsy with a relatively benign outcome, while 4 patients were affected by a severe form of epilepsy, with very frequent, drug-resistant, generalised and partial seizures with mental deterioration. One patient had a single episode of convulsive status epilepticus at four months of age. The neurological examination was normal in all patients. CT showed flocculo-nodular, cortico-subcortical BOC, without enhancement and without lobar or hemispheric atrophy. MRI was normal. The clinical and neuroimaging features of these patients are different therefore from those with the Sturge-Weber Syndrome. The study confirms a high prevalence of coliac disease in patients with BOC, but the relationship between these two pathologies still needs to be clarified. Images PMID:8350105

    Drug-induced liver injury (DILI) is an increasingly common cause of acute hepatitis. We examined clinical features and types of liver injury of 65 affected patients who underwent liver biopsy according DILI etiology. The major causes of DILI were the use of herbal medications (43.2%), prescribed medications (21.6%), and traditional therapeutic preparations and dietary supplements (35%). DILI from herbal medications, traditional therapeutic preparations, and dietary supplements was associated with higher elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels than was DILI from prescription medications. The types of liver injury based on the R ratio were hepatocellular (67.7%), mixed (10.8%), and cholestatic (21.5%). Herbal medications and traditional therapeutic preparations were more commonly associated with hepatocellular liver injury than were prescription medications (P = 0.002). Herbal medications and traditional therapeutic preparations induce more hepatocellular DILI and increased elevations in AST and ALT than prescribed medications. PMID:26713057

    Inflammatory fibroid polyps (IFPs) are rare, benign tumors that can arise throughout the gastrointestinal tract. Although the molecular pathogenesis of these lesions has been well characterized, their morphologic features often vary. We report the clinicopathologic findings of the largest series of IFPs to date. A total of 83 IFPs seen at our institution were collected between 1999 and 2012. The specimens included 64 biopsies and 19 resections. A review of the clinical features identified a modest female predominance (47 women and 36 men) with patients ranging in age from 26 to 87 years (mean, 60 y). Involved sites included the esophagus (n=2), stomach (n=31; mainly antrum), small intestines (n=17), appendix (n=1), large intestines (n=31; majority within the rectosigmoid), and anal canal (n=1). Although most patients had a nonspecific presentation, those with small intestinal lesions frequently presented with intussusception. Grossly, the tumors ranged in size from 0.2 to 4.2 cm (mean, 1.7 cm). Histologically, IFPs were centered within the submucosa in all resection specimens, but mucosal extension was found in 74 of 83 (89%) cases. The tumors varied in both cellularity and degree of vascularity. However, the characteristic feature of perivascular onion skinning was present in only 54% (45/83) of the cases. In addition, a short fascicular growth pattern was also noted in 36% (30 of 83) of cases, whereas both features were present in 14 cases (17%). Eosinophils were present in 94% (78 of 83) of cases but varied widely in number from abundant (20/hpf) to sparse (1/hpf). Interestingly, in those cases with sparse eosinophils, prominent hyalinization was also present (11 of 78, 13%). In addition, although the majority of IFPs expressed CD34, 6 of 44 (14%) were negative. No associated dysplasia or malignancy was seen. IFPs represent a diverse set of submucosal-based lesions that commonly extend into the mucosa, making them amenable to endoscopic biopsy. Although their

    BACKGROUND: Parapneumonic effusions complicating pneumonia are associated with increased morbidity and mortality. AIM: To determine the role of the clinical, laboratory and radiographic features to the differential diagnosis of patients with community- acquired pneumonia (CAP) without effusion, uncomplicated parapneumonic effusion (UCPPE) and complicated parapneumonic effusion (CPPE). MATERIAL AND METHODS: We analysed 148 patients with CAP without effusion, 50 with UCPPE and 44 with CPPE. In three groups of patients, the majority was male patients (58.11%, 58%, 61.36%) consequently. RESULTS: The chronic heart failure was the most common comorbidity in a group with CAP (28; 18.92%) and UCPPE (7; 14%), alcoholism (12;12.77%) in a group with CPPE. Patients with CPPE had significantly longer fever compared to patients with CAP without effusion (p = 0.003). Pleuritic chest pain (86.36%) and dyspnea (88.64%) were the most common symptoms in CPPE, then to group with UCPPE (60%; 52%), and in CAP without effusion (25.68%; 47,97%). Diffuse pulmonary changes were detected more frequently in the group with CAP without effusion compared with the group with CPPE (64.86 % vs. 27.27 %), while the segment lung changes were more common in patients with CPPE (50% vs. 20.27%). Patients with CPPE were significant with higher erythrocytes sedimentation rate (ESR), white blood cells (WBC) and serum C- reactive protein (CRP) than it the other two groups (p = 0.00090, p = 0.01, p= 0.000065). CONCLUSION: Proper analysis of clinical, laboratory and radiographic features of patients with CAP and parapneumonic effusion can prevent mismanagement in these patients and will reduce morbidity and mortality.

    Background Asthma–chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) is associated with rapid decline in lung function, poorer health-related quality-of-life outcomes, and frequent exacerbations, compared to COPD alone. Although the numbers of patients with ACOS have increased, there is little established evidence regarding diagnostic criteria and treatment options. Thus, the aim of our study was to clarify the clinical, physiological, and radiological features of patients with ACOS. Methods We examined a total of 100 patients with COPD and 40 patients with ACOS, who were selected based on clinical criteria. All patients underwent baseline testing, including a COPD assessment test, pulmonary function tests, and multidetector row computed tomography imaging. Percentage of low attenuation volume, percentage of wall area, and percentage of total cross-sectional area of pulmonary vessels less than 5 mm2 (%CSA <5) were determined using multidetector row computed tomography. ACOS patients were administered a fixed dose of budesonide/formoterol (160/4.5 μg, two inhalations; twice daily) for 12 weeks, after which the ACOS patients underwent multidetector row computed tomography to measure the same parameters. Results At baseline, the ACOS patients and COPD patients had a similar degree of airflow limitation, vital capacity, and residual volume. ACOS patients had higher COPD assessment test scores, percentage of wall area, and %CSA <5 than COPD patients. Compared to baseline, budesonide/formoterol treatment significantly increased the forced expiratory volume in 1 second and decreased the degree of airway wall thickness (percentage of wall area) as well as pulmonary microvascular density (%CSA <5) in ACOS patients. Conclusion Our results suggest that ACOS is characterized by an airway lesion–dominant phenotype, in contrast to COPD. Higher %CSA <5 might be a characteristic feature of ACOS. PMID:26028967

    Abstract Hepatitis C virus (HCV) genotype 3 infection is very rare in high-income Asia Pacific. The aim of our retrospective observational study was to evaluate the incidence, clinical features, and treatment outcomes of patients with a genotype 3 HCV infection in the Gyeongnam Province of Korea. Ninety-eight consecutive patients diagnosed with a genotype 3 HCV infection at Gyeongsang National University Hospital, between January 2005 and December 2014, were enrolled into the study. Relevant characteristics of the study group included: 80.6% men, mean age of 41.8 years, and including 69 patients with chronic hepatitis, 25 with liver cirrhosis, and 4 with hepatocellular carcinoma (HCC). Risk factors for HCV infection, sustained virologic response rate, development of HCC, and mortality in patients with genotype 3 were retrospectively analyzed. Among all patients diagnosed with a HCV infection during the study period, the prevalence of genotype 3 was 7.3%. The incidence of genotype 3 was higher in young patients with a risk factor of IVDU (54.0%) and tattooing (62.3%). Among 45 treatment-naive genotype 3 patients, sustained virologic response was achieved with a combination of pegylated-interferon alpha and ribavirin in 75.6%. The cumulative 5-year incidence of HCC was 13.6%, and 8.9% for overall mortality. Liver cirrhosis at enrollment was an independent risk factor for HCC development. This is the first study to elucidate the clinical features and outcomes among the patients with HCV genotype 3 infection in Korea. Further prospective studies are needed to investigate transmission routes and outcomes for HCV genotype 3 infections. PMID:26871824

    Longitudinally extensive myelopathy (LEM) is a rare spinal syndrome, and was mostly assessed in western populations. In order to investigate the etiological, clinical, and radiological features of LEM in Chinese patients, we retrospectively analyzed eighty-nine (40 men and 49 women, median age 45.9±15.7years) patients with LEM hospitalized in China-Japan Friendship Hospital. LEM comprised autoimmune inflammatory myelitis (n=53), metabolic and compressive disorders (n=13), vascular diseases (n=10), neoplastic diseases (n=7), infectious diseases (n=4), and syringomyelia (n=2). Neuromyelitis optica spectrum disorders (NMOSD) was the most common cause of transverse myelopathy identified in LEM (38/89 [42.7%]) characterized by intractable vomiting and hiccups and painful tonic spasms. Subacute combined degeneration and anterior spinal artery syndrome accounted for the largest non-transverse LEM, which selectively affected the spinal dorsal and/or lateral columns and the spinal anterior region, respectively. Radicular pain was common in anterior spinal artery syndrome. Postrema (n=15, 39.5%) and cervical (n=31, 81.6%) lesions were significantly increased in NMOSD versus non-NMOSD (n=7, 13.7% and n=34, 66.7%, respectively, p<0.05]. Axial T2-weighted MRI indicated that 46 (51.7%) patients exhibited complete lesions; 43 (48.3%) patients exhibited non-transverse lesions, mainly unilateral or symmetrical tract lesions. Twenty-four (51.1%) LEM patients exhibited distinct gadolinium contrast enhancement. In this Chinese cohort, LEM was primarily attributed to NMOSD. While the etiological distribution in the non-NMOSD group was different from western populations, clinical and imaging features may facilitate a differential diagnosis. PMID:27526974

    Venous thrombosis is common in older age, with an incidence of 0·5-1% per year in those aged >70 years. Stasis of blood flow is an important contributor to the development of thrombosis and may be due to venous insufficiency in the legs. The risk of thrombosis associated with clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, obtained with a standardized interview was assessed in the Age and Thrombosis Acquired and Genetic risk factors in the Elderly (AT-AGE) study. The AT-AGE study is a case-control study in individuals aged 70 years and older (401 cases with a first-time venous thrombosis and 431 control subjects). We calculated odds ratios (ORs) and corresponding 95% confidence intervals (CI) adjusted for age, sex and study centre. Varicose veins and leg ulcer were associated with a 1·6-fold (95% CI 1·2-2·3) and 3·3-fold increased risk of thrombosis (95% CI 1·6-6·7), respectively, while the risk was increased 3·0-fold (95% CI 2·1-4·5) in the presence of leg oedema. The risk of thrombosis was highest when all three risk factors occurred simultaneously (OR: 10·5; 95% CI 1·3-86·1). In conclusion, clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, are risk factors for venous thrombosis in older people.

    The aim of this was to assess clinical features and outcome in pediatric-onset Takayasu's arteritis (TA). Retrospective data analysis of patients diagnosed with TA over last 13 years with onset before 18 years of age was done. Their presenting features, activity (by NIH criteria, ITAS2010, ITAS-A), disease extent (by DEI.Tak) and angiographic findings were retrieved from clinic files. Treatment received and follow-up data on disease activity and damage by TA damage score (TADS) were also analyzed. Wherever repeated angiography data were available, the same was analyzed. Values are expressed as median with interquartile range in brackets. There were 29 patients (19 females) with median age at diagnosis of 14 (13-16) years and delay to diagnosis of 1 (0.4-2) year. Common presenting symptoms were pulse loss (23/29) and hypertension (22/29). Patients had extensive disease at presentation with median DEI.Tak of 12 (9.5-15); 23/29 had elevated acute-phase reactants, and 28/29 were active at presentation [median ITAS2010 13 (8-15.5), ITAS-A 14 (10-17)]. Numano's type V was the commonest angiographic type (22/29). At a median follow-up of 2.4 (1.5-5.1) years, 2/20 were active whereas all had sustained damage despite a majority (17/20) being on immunosuppression. The median TADS was 8 (6.3-9.8) with pulse loss, claudication and hypertension being the commonest damage item. Two needed renal artery stenting to control hypertension. Angiographic assessment at least 2 years apart demonstrated disease progression in 5 of 6 patients despite immunosuppression. Significant damage accrued on follow-up despite immunosuppression and control of disease activity. Hypertension remains the major long-term morbidity. PMID:25903354

    A 41-year-old male presented with progressive visual defects, acromegaly and hyperthyroidism. After clinical evaluation a giant GH/TSH-secreting pituitary adenoma was diagnosed. Administration of the somatostatin analog octreotide at doses of 150 microg s.c. per day inhibited the secretion of both GH and TSH. A three-week treatment with octreotide prior to surgery led to slight visual improvement and CT scan showed some new necrotic areas within the tumor mass. Transcranial surgery was performed. By immunohistochemical analyses of the adenoma tissue GH, prolactin and beta-chorionic gonadotropin were detected; TSH was negative. Electron microscopy revealed an undifferentiated, monomorphous adenoma with morphological features of an acidophil stem cell adenoma such as the presence of misplaced exocytoses, fibrous bodies and mitochondrial gigantism. However, the tumor cells contained small secretory granules (up to 250 nm) accumulated along the cell membrane characteristic of thyrotrope cells. Furthermore, some adenoma cells were fusiform with long cytoplasmic processes resembling thyrotropes. Two months after the operation CT scan revealed a large residual tumor. Serum GH and TSH levels had increased again and the TSH level was even higher than before the treatment. The patient died suddenly, most probably of lethal arrhythmia. Specimens of the adenoma tissue obtained at autopsy confirmed the previous findings with the exception of positive immunostaining for TSH which was found in less than 1% of the adenoma cells. This undifferentiated, monomorphous GH/TSH-secreting pituitary adenoma represents an entity that is unusual both in its ultrastructural features and clinical manifestations suggesting a cytogenesis from an early, undifferentiated stem cell.

    Objectives: Rotator cuff tears are a common and disabling complaint. The early diagnosis of medium and large size rotator cuff tears can enhance the prognosis of the patient. The aim of this study was to identify clinical features with the strongest ability to accurately predict the presence of a medium, large or multitendon (MLM) rotator cuff tear in a primary care cohort. Methods: Participants were consecutively recruited from primary health care practices (n = 203). All participants underwent a standardized history and physical examination, followed by a standardized X-ray series and diagnostic ultrasound scan. Clinical features associated with the presence of a MLM rotator cuff tear were identified (P<0.200), a logistic multiple regression model was derived for identifying a MLM rotator cuff tear and thereafter diagnostic accuracy was calculated. Results: A MLM rotator cuff tear was identified in 24 participants (11.8%). Constant pain and a painful arc in abduction were the strongest predictors of a MLM tear (adjusted odds ratio 3.04 and 13.97 respectively). Combinations of ten history and physical examination variables demonstrated highest levels of sensitivity when five or fewer were positive [100%, 95% confidence interval (CI): 0.86–1.00; negative likelihood ratio: 0.00, 95% CI: 0.00–0.28], and highest specificity when eight or more were positive (0.91, 95% CI: 0.86–0.95; positive likelihood ratio 4.66, 95% CI: 2.34–8.74). Discussion: Combinations of patient history and physical examination findings were able to accurately detect the presence of a MLM rotator cuff tear. These findings may aid the primary care clinician in more efficient and accurate identification of rotator cuff tears that may require further investigation or orthopedic consultation. PMID:24421626

By immunohistochemical analyses of the adenoma tissue GH, prolactin and beta-chorionic gonadotropin were detected; TSH was negative. Electron microscopy revealed an undifferentiated, monomorphous adenoma with morphological features of an acidophil stem cell adenoma such as the presence of misplaced exocytoses, fibrous bodies and mitochondrial gigantism. However, the tumor cells contained small secretory granules (up to 250 nm) accumulated along the cell membrane characteristic of thyrotrope cells. Furthermore, some adenoma cells were fusiform with long cytoplasmic processes resembling thyrotropes. Two months after the operation CT scan revealed a large residual tumor. Serum GH and TSH levels had increased again and the TSH level was even higher than before the treatment. The patient died suddenly, most probably of lethal arrhythmia. Specimens of the adenoma tissue obtained at autopsy confirmed the previous findings with the exception of positive immunostaining for TSH which was found in less than 1% of the adenoma cells. This undifferentiated, monomorphous GH/TSH-secreting pituitary adenoma represents an entity that is unusual both in its ultrastructural features and clinical manifestations suggesting a cytogenesis from an early, undifferentiated stem cell.
