    Tumoral calcinosis (TC) has long been a controversial clinico-pathological entity. Its pathogenesis and genetic background have been gradually unravelled since its first description in 1943. According to the presence or absence of an underlying calcifying disease process, TC has been divided into primary and secondary varieties. Two subtypes of the primary variety exist; a hyper-phosphatemic type with familial basis represented by mutations in GalNAc transferase 3 gene (GALNT3), KLOTHO or Fibroblast growth factor 23 (FGF23) genes, and a normo-phosphatemic type with growing evidence of underlying familial base represented by mutation in SAMD9 gene. The secondary variety is mainly associated with chronic renal failure and the resulting secondary or tertiary hyperparathyroidism. Diagnosis of TC relies on typical radiographic features (on plain radiographs and computed tomography) and the biochemical profile. Magnetic resonance imaging can be done in difficult cases, and scintigraphy reflects the disease activity. Treatment is mainly surgical for the primary variety; however, a stage-oriented conservative approach using phosphate binders, phosphate restricted diets and acetazolamide should be considered before the surgical approach is pursued due to the high rate of recurrences and complications after surgical intervention. Medical treatment is the mainstay for treatment of the secondary variety, with failure warranting subtotal or total parathyroidectomy. Surgical intervention in these patients should be kept as a last resort. PMID:25232542

    Chronic macrocheilia has a multifactorial aetiology and is often a diagnostic and therapeutic challenge. Epidemiological information on this condition is scarce, most of the data reported relating only to granulomatous cheilitis. We have performed a detailed clinico-pathological analysis of all patients with chronic macrocheilia presenting to us during the last 6.5 years. Of the 28 patients identified, 13 (46.4%) had granulomatous cheilitis (GC), six (21.4%) had tuberculosis of the lip, three (10.7%) had leprous macrocheilia, two (7.1%) had multiple endocrine neoplasia type IIb, and one each had Ascher's syndrome and non-Hodgkin's lymphoma. Two patients were diagnosed as 'nonspecific cheilitis'. Histopathological differentiation between tuberculosis and GC was often not possible; but PCR for Mycobacterium tuberculosis was positive in all patients with tuberculosis and negative in four patients with GC in whom M. tuberculosis was sought. In spite of detailed clinical examination and investigations, a therapeutic trial was required to confirm the diagnosis in five (17.9%) patients. We have reviewed the available literature on this subject, and to our knowledge this study is the first of its kind. More such studies from other centres will help physicians to make an accurate aetiological diagnosis and treat this uncommon but disfiguring condition with confidence.

    The paper is devoted to clinico-roentgenological correlations of venous reno-gonadal hemodynamics in 168 women of reproductive age (151 women with infertility, habitual abortion, disordered menstrual function and 17 patients without disorders of the reproductive tract). Clinico-laboratory investigation was followed by visceral and parietal phlebography for the detection of a pathological venous reflux into the ovarian pampiniform plexus. A retrograde blood flow along the internal ovarian vein with the development of venostasis and secondary pelvic varicocele was diagnosed in 67 women with disturbed reproductive function. In 17 women without disorders of reproductive function a reno-gonadal venous reflux was undetectable. Clinico-roentgenological semiotics of chronic venous ovarian insufficiency was analyzed. Infertility was shown to be the main clinical manifestation of ovarian varicocele.

    Genetically modified corn Bt11 is insect-resistant and expresses Cry1Ab toxin, an insecticidal protein, in kernels. Although Bt11 corn is considered safe based on animal performance, there are no reports available on the clinico-biochemical effects of feeding it to cattle. In this study, we evaluated the effects of feeding Bt11 to calves, using blood and ruminal clinico-biochemical parameters. Our three-month-long feeding experiment demonstrated that calves (n=6), fed with a ration containing 43.3% of Bt11 corn kernels as dry matter, did not develop any discernible clinical, hematological, biochemical, or ruminal abnormalities as compared with control calves (n=6) fed non-Bt11 corn. The results suggest that the transgenic Bt11 has no negative clinico-biochemical effects on calves.

    Pulmonary alveolar microlithiasis (PAM) is a rare infiltrative lung disease characterized by deposition of spherical calcium phosphate microliths called calcospherites within the alveoli. PAM was first described by Friedrich in 1856 and then by Harbitz in 1918. The disease pathogenesis is based on mutations in the SLC34A2 gene that encodes for the Type IIb sodium-phosphate cotransporter. The majority of the patients are diagnosed at an early age, usually between the ages of 20 and 40 years. The hallmark of this disease is a striking dissociation between the radiological findings and the mild clinical symptoms.  We report a case of 35-year-old woman who presented post-motor vehicle accident with back pain and with minimal dyspnea on exertion. The final diagnosis was made after computed tomography and lung biopsy. The present case exhibits the remarkable clinico-radiological dissociation with complete calcification of the lungs on radiographic images with a relatively mild clinical presentation.

    Neck is the most common site of peripheral lymph node enlargement and is very frequently encountered in oto-laryngological practice. This study was done to delineate distribution of clinico-demographic parameters in patients presenting with cervical lymphadenopathy in the otolaryngology out-patient department of a state hospital in India in a 1 year period and to correlate them with fine needle aspiration cytological diagnosis. Record-based cross sectional study in the department of Otolaryngology and department of Pathology, Calcutta National Medical College and Hospital, Kolkata. Case reports and cytological reports of 423 patients who underwent Fine Needle Aspiration Cytology (FNAC) of cervical lymph nodes between January 2009 and December 2009 were reviewed in relation to their demographic and clinical profiles. The cases were divided into three groups according to age and different parameters were described according to these groups. In the cyto-pathological diagnosis, tubercular lymph-adenitis was most prevalent diagnosis (45.4%). Among the metastatic secondaries, squamous cell carcinoma was most common (8.5%). Non-specific/reactive lymphadenitis was significantly more common in <14 years, TB lymph node in 15-59 years and malignancy among the ≥60 years age group. Jugulo-omohyoid (level III) and Supraclavicular (level VB) groups of Lymph nodes were found significantly more involved by malignancy whereas Jugulo-diagastric (level II), Post-auricular, Submandibular groups (level IB) were more commonly involved in TB. Malignancy patients presented late in respect to the tuberculosis patients. Knowledge about clinico-demographic perspectives of cervical lymphadenopathy in respect to their cytopathological diagnosis will help care giver practioners to detect/refer the respective cases early for investigations and treatment.

    Introduction Infectious Granulomatous Dermatoses (IGDS) have various aetiological factors with a considerable overlap in the histopathological and clinical features, thus posing a diagnostic dilemma for dermatologists and pathologists. Aim We aimed at determining the histopathological profile of IGDS correlating it with clinical features with an attempt to find the aetiology. Materials and Methods In a cross-sectional study conducted in a tertiary referral center of Mumbai over two years, out of 1872 skin biopsies received, 239 histopathologically diagnosed cases of IGDS were studied for histopathological features of granuloma. A clinico-histopathological correlation was attempted. Chi-square test was used for comparison of proportions of different groups. Results Leprosy (211 cases) and tuberculosis (28 cases) were the commonest histopathologically diagnosed IGDS. Leprosy spectrum included BT (30.33% cases), followed by TT (21.32%), BL and LL and 21.79% cases of lepra reactions. Skin TB biopsies on histopathology showed lupus vulgaris (53.85% cases), scrofuloderma (15.38%), TBVC and papulonecrotic tuberculid (11.54% each). In leprosy maximum clinico-pathological agreement was seen at tuberculoid pole (TT 72.7% and BT 56.6%). Among tuberculosis cases, scrofuloderma (100%) and lupus vulgaris (53.8%) showed maximum agreement. Conclusion Leprosy and skin TB are the commonest IGDS in Mumbai region though difficult to diagnose and subcategorize with certainty during initial stages. Histopathology plays the important role to elucidate the dilemma. This being a single center study, more such studies with a larger sample size are recommended to get more elaborate data and regional prevalence of these IGDS for a better overall approach to prevention, treatment and control.

    A clinico-epidemiological study of fever cases was carried out in three villages of Ambajogai Mandal, Beed, Maharashtra. Out of 123 fever cases studied, most common affected age group was 21-45 years with more number of females i.e. 55.28%. The patients mainly presented with fever and joint pain with no any evidence of haemorrhagic manifestation. Of the 36 blood samples tested 03 samples were found positive for IgM antibodies to dengue virus. Larval survey showed highest breeding preference in domestic water container like earthen pots. Entomological indices were found out to be higher as house index 19.76%; container index 19.02%; Breteau index 22.31%. Clinico-epidemiological, laboratory and entomological investigations indicate present episode of fever outbreak was due to dengue fever. It demands for strengthening the surveillance activity and alert reporting of peripheral health staff along with IEC activities for community participation and involvement of other departments.

    Blastic plasmacytoid dendritic cell neoplasm is a rare clinicopathologic entity, characterized by strong skin tropism and a poor prognosis. The diagnosis is generally made by skin biopsy with appropriate immunohistochemical studies. To identify potential biological prognostic factors for blastic plasmacytoid dendritic cell neoplasm, we performed an extended clinico-immunohistochemical study on a series of 91 well-documented cases collected since 1995 by the French Study Group on Cutaneous Lymphomas. Skin biopsies were analyzed using a panel of 12 immunohistochemical markers (CD4, CD56, CD123, CD303, TCL1, CD68, CD2, CD7, TdT, Ki-67, S100, and MX-1). The results were correlated with survival. The 5 most characteristic markers of this entity (CD4, CD56, CD123, CD303, and TCL1) were expressed simultaneously in only 46% of patients. However, when 4 markers were expressed the diagnosis could still be reliably made without resorting to any additional stains. Expression of TdT and/or S100 correlated with varying degrees of maturation. Statistical survival analyses showed that CD303 expression and high proliferative index (Ki-67) were significantly associated with longer survival.

    Osteosarcomas of hands or feet are rare, and seemingly these cases differ in presentation and behavior compared to those in usual locations. The clinico-pathological presentation of patients with osteosarcomas of the hand or foot was studied and compared with published cases. Forty osteosarcomas were identified among 4,221 cases, representing 0.95 % of all osteosarcomas. Thirty of these were well documented. Mean age at diagnosis was 43 years (hands) and 36 years (feet) and male-female ratio was 1.2:1 and 2.0:1, respectively. In the hand, 62 % of the osteosarcomas presented in the metacarpals and 23 % in the phalanges, and only two cases occurred in the carpal bones. Distribution in the foot was tarsal bones 56 %, metatarsal bones 33 %, and phalanges 11 %.Of the cases in the hand 54 % were of high grade and of those in the foot 71 %. Survival of osteosarcomas of the hand or foot was 81 %. Only patients with high-grade osteosarcoma died of the disease. Histological grade was the only significant variable related to survival. High-grade osteosarcoma of the hand or feet should be treated similar to those in conventional sites. Osteosarcomas of hands or feet are rare and in a relative high proportion are of low grade. Survival in high-grade cases is comparable to that in conventional sites.

    Disinhibition is an important symptom in neurodegenerative diseases. However, the clinico-anatomical underpinnings remain controversial. We explored the anatomical correlates of disinhibition in neurodegenerative disease using the perspective of grey and white matter imaging. Disinhibition was assessed with a neuropsychological test and a caregiver information-based clinical rating scale in 21 patients with prefrontal syndromes due to behavioural variant frontotemporal dementia (n = 12) or progressive supranuclear palsy (n = 9), and healthy controls (n = 25). Cortical thickness was assessed using the Freesurfer software on 3T MRI data. The integrity of selected white matter tracts was determined by the fractional anisotropy (FA) from Diffusion Tensor Imaging. Disinhibition correlated with the cortical thickness of the right parahippocampal gyrus, right orbitofrontal cortex and right insula and the FA of the right uncinate fasciculus and right anterior cingulum. Notably, no relationship was seen with the thickness of ventromedial prefrontal cortex. Our results support an associative model of inhibitory control, distributed in a medial temporal lobe-insular-orbitofrontal network, connected by the intercommunicating white matter tracts. This reconciles some of the divergences among previous studies, but also questions the current conceptualisation of the “prefrontal” syndrome and the central role attributed to the ventromedial prefrontal cortex in inhibitory control.

    Human cystic echinococcosis (CE) is an endemic disease in the Mediterranean area that has not yet been fully documented in western Libya. The present study describes the clinico-epidemiologic profile of CE in western Libya's Nalut district. From April 2008 to July 2011, 36 cases of CE were confirmed following surgical removal of cysts. The cysts were most frequently found in the liver (61.1%), followed by the lungs (19.4%), kidneys (11.1%), peritoneal cavity (11.1%), and spleen (5.6%). Among the 36 patients, 6 possessed plural cysts and 3 had cysts in 2 organs. Blood samples from this group were examined for the presence of serum anti-hydatid IgG antibodies, which revealed positivity in 25 patients (69.4%). An additional 300 blood samples were collected randomly from the inpatient and outpatient clinics at Nalut Hospital. Twenty-seven samples (9%) were found to be positive for the anti-hydatid IgG antibody among which the prevalence of infection tended to be higher in men (12%) than in women (6%). This study demonstrates that CE is a major parasitic infectious disease of public health significance in Libya, notably in the western part of the country, and that disease awareness needs to be raised nationwide.

    An important goal of research involving gene expression data for outcome prediction is to establish the ability of genomic data to define clinically relevant risk factors. Recent studies have demonstrated that microarray data can successfully cluster patients into low- and high-risk categories. However, the need exists for models which examine how genomic predictors interact with existing clinical factors and provide personalized outcome predictions. We have developed clinico-genomic tree models for survival outcomes which use recursive partitioning to subdivide the current data set into homogeneous subgroups of patients, each with a specific Weibull survival distribution. These trees can provide personalized predictive distributions of the probability of survival for individuals of interest. Our strategy is to fit multiple models; within each model we adopt a prior on the Weibull scale parameter and update this prior via Empirical Bayes whenever the sample is split at a given node. The decision to split is based on a Bayes factor criterion. The resulting trees are weighted according to their relative likelihood values and predictions are made by averaging over models. In a pilot study of survival in advanced stage ovarian cancer we demonstrate that clinical and genomic data are complementary sources of information relevant to survival, and we use the exploratory nature of the trees to identify potential genomic biomarkers worthy of further study.

    The authors conducted a clinico-epidemiological study of schizophrenics among the indigenous population, including that living in isolated areas and newcomers, taking into consideration forms of the disease course and employing a uniform syndromal assessment of the mental state. The authors have established general pathogenetic regularities of the course and their relationship with the age and sex. Patients from the indigenous population, particularly of geographically isolated areas, showed a higher incidence of schizophrenia, a more severe clinical picture of the disease and a lower level of social and occupational adaptation as compared to the migrated population.

    2013-01-01

    This review focuses on six key papers published in the mid 2000 s based on work conducted in Cambridge. The first two relate to clinico-pathological studies which established that Alzheimer's disease (AD) is a relatively common cause of focal cortical syndromes, notably progressive aphasia (largely nonfluent), progressive apraxia, and posterior cortical atrophy with complex visual symptoms. Building on these findings, criteria for the progressive aphasias have been developed which define the variant associated with AD (progressive logopenic aphasia). Memory in the dementias has been a major area of interest and one paper discussed here explored the neural basis for episodic and semantic memory failure in AD and semantic dementia. Despite very different memory profiles, the two disorders both cause severe hippocampal hypometabolism and atrophy but differ in the degree of involvement of other memory related structures. This work drew attention to the role of pathology in non-hippocampal structures early in AD. The next two articles deal with the behavioral variant frontotemporal dementia (bvFTD) which we have shown is associated with breakdown in theory of mind, social reasoning, empathy, and emotion processing and contributed towork on the neural basis of social cognition. We also identified a subgroup of bvFTD who fail to progress over many years, termed phenocopy cases, who are differentiated by their lack of atrophy on MRI. The final paper described the application of the Addenbrooke's Cognitive Examination-Revised, which has proven a useful brief assessment tool for the early detection of a range of neurodegenerative disorders including AD and FTD. It also appears to be helpful in predicting those with mild cognitive impairment who will progress to frank dementia. PMID:22766737

    Neuroblastoma, an embryonal malignancy of the sympathetic nervous system, is the most frequent extracranial solid tumor The clinico-epidemiological features of neuroblastoma in infants and children were investigated between January 2005 and January 2010 at the Pediatric Oncology units of Mansoura, Zagazig, and Tanta University Children's Hospitals (Egypt). Of 142 cases of neuroblastoma, 10 were omitted from the study due to defective data. The median age of the patients was 30 months, with 75.8% aged ≥1 year and 24.2% aged <1 year at time of diagnosis. The male-to-female ratio was 1.06. Suprarenal glands were the most common primary tumor site (72.7%). The majority of the patients (76.7%) had stage IV disease. Favorable pathology was observed in 43.8% of patients, while 56.2% exhibited unfavorable pathology. The estimated survival rate of patients was 30.7±10.0%, and mean survival time was 24.2±5.2 months. The rate of mortality was 28.6% for patients aged <1 year, and 81.8% for those aged ≥1 year (P=0.005). For patients with favorable pathology, the rate of mortality was significantly lower (28.6%) compared with that of patients with unfavorable pathology (77.8%; P=0.049). Although the association between outcome and each of the primary tumor sites, children's oncology group risk and gender was statistically insignificant, a large effect size was identified between outcome and primary tumor site, as well as children's oncology group risk and a medium effect size was identified between outcome and gender. Additionally, an age of ≥1 year was associated with unfavorable pathology (P=0.024), stage IV disease (P=0.026) and a suprarenal primary tumor site (P=0.001). PMID:26622625

    Recently, the numbers of lung transplantation (LT) has been increased in Korea. However, post-LT outcome has not been successful in all patients, which may be partially affected by the primary lung disease. Therefore comprehensive understanding in original pathological diagnosis of patients with LT would be needed for achieving better clinical outcome. To address this issue, we performed clinico-pathological analysis of the explanted lungs from 29 patients who underwent LT over a 9-yr period in Seoul National University Hospital. Among them, 26 patients received single (1/26) or double (25/26) LT, while heart-lung transplantation was performed in 3 patients. The final clinico-pathological diagnoses were idiopathic pulmonary fibrosis/usual interstitial pneumonia (UIP) (n = 6), acute interstitial pneumonia (AIP)/diffuse alveolar damage (DAD) (n = 4), AIP/non-specific interstitial pneumonia with DAD (n = 1), collagen vascular disease-related interstitial lung disease (CVD-ILD)/DAD (n = 3), CVD-ILD/UIP (n = 1), lymphangioleiomyomatosis (n = 1), bronchiectasis (n = 4), pulmonary arterial hypertension (n = 2), tuberculosis (n = 1), bronchiolitis obliterans (BO) (n = 1), and lung cancer (n = 1). Moreover, 4 patients who had chemotherapy and hematopoietic stem cell transplantation due to hematologic malignancy showed unclassifiable interstitial pneumonia with extensive fibrosis in the lungs. Our study demonstrates that pathology of the explanted lungs from Korean patients with LT is different from that of other countries except for interstitial lung disease and bronchiectasis, which may be helpful for optimization of selecting LT candidates for Korean patients.

    Background: Granulomatous dermatoses are common skin pathology, often need histopathological confirmation for diagnosis. Histologically six sub-types of granulomas found in granulomatous skin diseases- tuberculoid, sarcoidal, necrobiotic, suppurative, foreign body & histoid type. The aims of the present study were clinico-pathological evaluation of granulomatous skin lesions and their etiological classification based on histopathological examination. Methods: It was a five years (Jan 2009- Dec 2013) retrospective study involving all the skin biopsies. Detailed clinical and histopathological features were analyzed and granulomatous skin lesions were categorized according to type of granuloma & etiology. Special stains were used in few cases for diagnostic purpose. Results: Among 1280 skin biopsies, 186 cases (14.53%) were granulomatous skin lesions with a ratio 1:24. In histopathological sub-typing, tuberculoid granuloma was most common type (126 cases, 67.74%). Most common etiology of granuloma in the study was leprosy (107 cases, 57.52%). Other etiologies were cutaneous tuberculosis, foreign body granulomas, fungal lesions, cutaneous leishmaniasis, sarcoidosis and granuloma annulare. Conclusion: Histopathology is established as gold standard investigation for diagnosis, categorization and clinico-pathological correlation of granulomatous skin lesions. PMID:26870144

    The HexLoc locking system was designed to prevent back-side wear of the polyethylene liner in the modular cementless metal-backed acetabular cup, but failed. Back-side wear was analyzed using clinico-radiological data, immunohistopathology, finite element modeling (FEM, and retrieval analysis. Screw holes allowed entry of titanium oxide and exit of polyethylene particles. Birefringent polyethylene wear particles were found behind the metal cup in macrophages containing pro-inflammatory tumor necrosis factor-α and interleukin-1β, whereas fibroblast-like cells stained for osteoclastogenic receptor activator of nuclear factor kappa B ligand (RANKL). Computerized tomography revealed granulomas (83% versus 17 %) and cortical destruction (50% versus 5%) better than radiographs. In FEM, a change of the abduction angle from 45 to 60 deg, and liner thickness from 4.8 mm to 2.5 mm, increased the back-side wear by 90% and 120%, respectively. Screw holes were stress concentration areas; their removal decreased wear by 40%. Modeling results were validated in retrieved implants, which demonstrated extensive back-side wear damage of liners with a high abduction angle. Combined clinico-radiological, immunohistopathological, FEM, and retrieval analysis disclosed that back-side wear in the HexLoc design is sensitive to the abduction angle, liner thickness, and presence of screw holes.

    Onchocerciasis is a disease of public health and socio-economic importance in Ethiopia. The aim of this study was to assess parasitological and clinico-epidemiological features of onchocerciasis in the Anfilo District, West Wellega, prior to implementation of Community Directed Treatment with Ivermectin (CDTI) to generate epidemiological and parasitological data for use in control program of the disease and subsequent evaluation of CDTI. A cross-sectional study was conducted in Anfilo District of West Wellega zone during a period of 1 month: from mid-August to mid-September 2006. Data on socio-demographic characteristics were collected using a standardized questionnaire prepared for this purpose. All persons were examined clinically for skin signs and symptoms of onchocerciasis. Two skin snips, one from each side of the gluteal fold were taken using blood lancet and sterilized razor blade and examined for microfilaria. All data were categorized, coded, entered in a data base and analyzed using SPSS version 15.0. for windows. A total of 1114 individuals ≥15 years were examined for microfilariae (mf) of Onchocerca volvulus and onchocercal skin disease (OSD). The prevalence of onchocercal (mf) carrier was 74.8% (833/1114). In both genders, the prevalence of onchocerciasis showed direct correlations with the age of individuals (R (2) = 0.79, P < 0.05). The infection rate varied with the occupation of the study subjects, with preponderance among farmers. Among the subjects with onchocerciasis, the mf density ranged from 1.0 to 711.0 per mg of skin snip with a mean density (SD) and median values of 32.1 (61.5) and 10.4 respectively. The overall community microfilariae load (CMFL), the most sensitive parasitological indicator of onchocerciasis was 19.6. The pervasiveness of OSD among the study subjects was 26.4%. OSD was more frequent in males (32.4%) than their female counterparts (20.8%, P < 0.05). The overall prevalence of onchocercal nodule carrier, the

    An exhaustive clinico-biochemical examination of the population of two kishlaks of the Samarkand Region, viz. Karakent (210 persons) and Ishan (248 persons) was carried out. The program of this examination permitted to exclude over 160 forms of hereditary pathology. A total of 45 persons affected with diseases belonging to 12 nosological forms were revealed in the course of the examination. Among the diseases observed only 5 are hereditary sensu stricto, viz. myoclonus-epilepsy, Bonevi-Ulrich's syndrome, imperfect osteogenesis, pigment choreoretinite and Down's syndrome, others belong to diseases with a pronounced hereditary predisposition. The main part of this group comprises neuro-psychic diseases, such as non-differentiated olygophreny (5.0%), epilepsy (1.3%), schizophreny; many of these cases have a familial character, particularly in Karakent. Besides the persons suffering from diseases, 20 heterozygous carriers of beta-thalassemia and 17 heterozygous carriers of G6PD-deficiency were discovered in the kishlaks examined. On the whole the frequency of the diseases revealed did not exceed the level in the general population. Despite the different degree of isolation of the kishlaks examined (Karakent is isolated on a religious basis, F = 0.0064; while Ishan is a desintagrated isolate, F = = 0.0014), no substantial differences between them in the distribution of pathological phenomena were observed. On the basis of the experience of this expedition recomendations are proposed concerning the origination and accomplishment of medico-genetic expeditions. A scheme is proposed for the performance of medico-genetic examination through several stages. The first stage in the composition of tentative maps of the distribution of hereditary diseases within a region on the basis of the information obtained from the medical personnel and from the examination of the documents of district and regional hospitals. Subsequently the primary information is specified, the regions to

    Purpose To correlate the differentially expressed miRNAs with clinico-pathological features in uveal melanoma (UM) tumors harbouring chromosomal 3 aberrations among South Asian Indian cohort. Methods Based on chromosomal 3 aberration, UM (n = 86) were grouped into monosomy 3 (M3; n = 51) and disomy 3 (D3; n = 35) by chromogenic in-situ hybridisation (CISH). The clinico-pathological features were recorded. miRNA profiling was performed in formalin fixed paraffin embedded (FFPE) UM samples (n = 6) using Agilent, Human miRNA microarray, 8x15KV3 arrays. The association between miRNAs and clinico-pathological features were studied using univariate and multivariate analysis. miRNA-gene targets were predicted using Target-scan and MiRanda database. Significantly dys-regulated miRNAs were validated in FFPE UM (n = 86) and mRNAs were validated in frozen UM (n = 10) by qRT-PCR. Metastasis free-survival and miRNA expressions were analysed by Kaplen-Meier analysis in UM tissues (n = 52). Results Unsupervised analysis revealed 585 differentially expressed miRNAs while supervised analysis demonstrated 82 miRNAs (FDR; Q = 0.0). Differential expression of 8 miRNAs: miR-214, miR-149*, miR-143, miR-146b, miR-199a, let7b, miR-1238 and miR-134 were studied. Gene target prediction revealed SMAD4, WISP1, HIPK1, HDAC8 and C-KIT as the post-transcriptional regulators of miR-146b, miR-199a, miR-1238 and miR-134. Five miRNAs (miR-214, miR146b, miR-143, miR-199a and miR-134) were found to be differentially expressed in M3/ D3 UM tumors. In UM patients with liver metastasis, miR-149* and miR-134 expressions were strongly correlated. Conclusion UM can be stratified using miRNAs from FFPE sections. miRNAs predicting liver metastasis and survival have been identified. Mechanistic linkage of de-regulated miRNA/mRNA expressions provide new insights on their role in UM progression and aggressiveness. PMID:26812476

    Hippocampal anatomy and network organization are capable to generate drug-resistant temporal lobe epilepsy (TLE) in humans and particularly vulnerable to segmental neuronal cell loss. Surgical hippocampectomy has been proven successful in treatment and available human tissue specimens allow systematic clinico-pathological examination. Different patterns of hippocampal cell loss have been identified in TLE patients and are recently classified by the International League against Epilepsy (ILAE) into four distinct subtypes in order to stratify the heterogenous group of TLE patients also with respect to postsurgical outcome. Another important aim of the international consensus classification system of hippocampal sclerosis (HS) is to gain further insights into the morpho-functional organization of human memory frequently compromised in TLE patients.

    Penile squamous cell carcinoma is a rare disease, in which somatic genetic aberrations have yet to be characterized. We hypothesized that gene copy aberrations might correlate with human papillomavirus status and clinico-pathological features. We sought to determine the spectrum of gene copy number aberrations in a large series of PSCCs and to define their correlations with human papillomavirus, histopathological subtype, and tumor grade, stage and lymph node status. Seventy formalin-fixed, paraffin embedded penile squamous cell carcinomas were centrally reviewed by expert uropathologists. DNA was extracted from micro-dissected samples, subjected to PCR-based human papillomavirus assessment and genotyping (INNO-LiPA human papillomavirus Genotyping Extra Assay) and microarray-based comparative genomic hybridization using a 32K Bacterial Artificial Chromosome array platform. Sixty-four samples yielded interpretable results. Recurrent gains were observed in chromosomes 1p13.3-q44 (88%), 3p12.3-q29 (86%), 5p15.33-p11 (67%) and 8p12-q24.3 (84%). Amplifications of 5p15.33-p11 and 11p14.1-p12 were found in seven (11%) and four (6%) cases, respectively. Losses were observed in chromosomes 2q33-q37.3 (86%), 3p26.3-q11.1 (83%) and 11q12.2-q25 (81%). Although many losses and gains were similar throughout the cohort, there were small significant differences observed at specific loci, between human papillomavirus positive and negative tumors, between tumor types, and tumor grade and nodal status. These results demonstrate that despite the diversity of genetic aberrations in penile squamous cell carcinomas, there are significant correlations between the clinico-pathological data and the genetic changes that may play a role in disease natural history and progression and highlight potential driver genes, which may feature in molecular pathways for existing therapeutic agents.

    Background Claudin and occludin are the important tight junctions protein in human. The downregulation or upregulation of claudins and occludin might have a role in cancer development. The objective of this study was to investigate the expression of claudin-5, claudin-7 and occludin in oral squamous cell carcinoma (OSCC) and their relationships with the prognostically-related clinico-pathologic features. Material and Methods Standard indirect immunohistochemical technique using anti-claudin-5, anti-claudin-7 and anti-occludin was performed in formalin-fixed paraffin-embedded tissue sections of 66 OSCC samples from Faculty of Dentistry, Chulalongkorn University. The positive cases were divided into 2 groups, the low expression group (cases with less than 50% of positive cancer cells) and the high expression group for statistical analysis. Categorical analysis of the clinico-pathologic parameters together with univariate analysis using the Kaplan-Meier method and the log rank test were performed. Results There were 22 male and 23 female patients enrolled in this study, with a mean age of 65.82+12.10 years. The claudin-5 immunoreactivity was observed in 26.6% of cases. The positive immunoreactivity of claudin-7 is more noted (93.3%). Only 4 cases showed occludin immunoreactivity (8.9%) and all of them show positivity less than 25% of cancer cells. Only loss of claudin-7 expression was associated with the high pathologic grade, advanced TNM staging, large tumor size, the presence of microscopic perineural, vascular invasions and regional lymph node involvement. There is a tendency towards the association of the higher claudin-7 expression and a longer survival time (P=0.012). Conclusions The results showed expression of claudin-5, claudin-7 and low expression of occludin in OSCC. Only claudin-7 expression showed impact on clinic-pathological parameter of OSCC. Key words:Claudin, occludin, oral squamous cell carcinoma, tight junctions, oral cancer. PMID:27398181

    The concept of Dejerine-Sottas disease, which corresponds to presumed recessive demyelinating neuropathies with onset in infancy, remains controversial. To learn more on the subject, we performed a clinico-pathological and molecular genetic study in 15 unrelated patients with the Dejerine-Sottas phenotype seen over a 16 year period. There were 12 females and 3 males, born to asymptomatic parents. Study of the PMP22, P0 and Egr2 genes was performed in all cases and 14 underwent a nerve biopsy. First manifestations of neuropathy occurred before 3 years of age in all patients. An inherited disorder was suspected in 10 patients, because of their family history and/or disclosure of a molecular genetic defect in 4 of them. One patient had a recessively transmitted homozygous point mutation (Arg157Trp) of the PMP22 gene. A heterozygous duplication of the 17p11.2-12 segment was detected in one offspring of a consanguineous marriage. One patient carried a "de novo" heterozygous Ser72Leu substitution in the PMP22. A heterozygous double mutation of the P0 gene including a "de novo" Val42 deletion and an Ala221Thr substitution, maternally inherited, were found in an apparently sporadic case. No mutation of the Egr2 gene was identified. A neuropathy with focally folded myelin sheaths (CMT4B) was diagnosed in the nerve biopsy specimens of two patients. In five patients, the clinico-pathological findings along with the absence of an identified mutation suggested the diagnosis of chronic inflammatory demyelinating polyneuropathy of infantile onset. Our findings illustrate the genetic heterogeneity of cases with identified mutations, the scarcity of cases with "demonstrated" recessive transmission and the likelihood of early acquired chronic inflammatory demyelinating polyneuropathy in several patients.

    About 5–10% of breast cancers are hereditary; a genetically and clinically heterogeneous disease in which several susceptibility genes, including BRCA1, have been identified. While distinct tumour features can be used to estimate the likelihood that a breast tumour is caused by a BRCA1 germline mutation it is not yet possible to categorize a BRCA1 mutated tumour. The aim of the present study is to molecularly classify BRCA1 mutated breast cancers by resolving gene expression patterns of BRCA1 and matched sporadic surgical breast tumour specimens. The expression profiles of 6 frozen breast tumour tissues with a proven BRCA1 gene mutation were weighed against those from 12 patients without a known family history but who had similar clinico-pathological characteristics. In addition two fibroblast cultures, the breast cancer cell-line HCC1937 and its corresponding B-lymphoblastoid cell line (heterozygous for mutation BRCA1 5382insC) and an epithelial ovarian cancer cell line (A2780) were studied. Using a high density membrane based array for screening of RNA isolated from these samples and standard algorithms and software, we were able to distinguish subgroups of sporadic cases and a group consisting mainly of BRCA1-mutated breast tumours. Furthermore this pilot analysis revealed a gene cluster that differentially expressed genes related to cell substrate formation, adhesion, migration and cell organization in BRCA1-mutated tumours compared to sporadic breast tumours. © 2001 Cancer Research Campaign http://www.bjcancer.com PMID:11506493

    In order to study interrelations between schizophrenia forms and the constitutional morphological type of the patients, as many as 840 schizophrenic patients and 282 normal subjects of the control group underwent ++clinico-anthropometric examinations. Comparison of the distribution of the pyknic, normosthenic and asthenic types of build-up in patients with schizophrenia and in the control group of healthy subjects did not reveal material differences and tropism of this endogenous psychosis to the constitution. It has been shown at the same time that at the probability level, the asthenic somatotype is the basis for continuous-progressive forms of the disease; the pyknic type of the build-up is based on the recurrent and shift-like forms with circular features, whereas the normosthenic somatic type forms the basis for the attack-like progressive form. The data obtained permit a conclusion that formation of schizophrenia forms is determined not only by the general pathological regularities common to the given disease but also by the individual typological peculiarities characteristic of different ++morpho-phenotypes of constitution.

    The relationship between clinico-biochemical characteristics and self reported psychological parameters in 42 women with polycystic ovary syndrome (PCOS) and 42 age-matched healthy controls was examined. The General Health Questionnaire was used (GHQ-12) to ascertain emotional distress and the Beck Depression Inventory (BDI) to determine depressive symptoms. Emotional distress, depressive symptoms, hirsutism score, body mass index (BMI), waist-to-hip ratio (WHR), luteinizing hormone/follicle-stimulating hormone ratio, serum total testosterone, dehydroepiandrosterone sulphate levels and the insulin resistance index were significantly greater in women with PCOS than in healthy women. The BDI and GHQ-12 scores of the women with PCOS were significantly higher than those of the control group (BDI, 11.69 +/- 9.49 vs 5.80 +/- 4.58; GHQ-12, 3.38 +/- 3.38 vs 1.54 +/- 1.97, respectively), and BMI and WHR were positively correlated with the BDI and GHQ-12 scores. Clinicians should be aware of the increased risk of emotional distress and depression in women with PCOS, especially those who are obese, and of the need to screen these patients for such symptoms.

    Frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS) are types of major TDP-43 (43-kDa TAR DNA-binding protein) proteinopathy. Cortical TDP-43 pathology has been analyzed in detail in cases of FTLD-TDP, but is still unclear in cases of ALS. We attempted to clarify the cortical and subcortical TDP-43 pathology in Japanese cases of sporadic ALS (n = 96) using an antibody specific to phosphorylated TDP-43 (pTDP-43). The cases were divided into two groups: those without pTDP-43-positive neuronal cytoplasmic inclusions in the hippocampal dentate granule cells (Type 1, n = 63), and those with such inclusions (Type 2, n = 33). Furthermore, the Type 2 cases were divided into two subgroups based on semi-quantitative estimation of pTDP-43-positive dystrophic neurites (DNs) in the temporal neocortex: Type 2a (accompanied by no or few DNs, n = 22) and Type 2b (accompanied by abundant DNs, n = 11). Clinico-pathologic analysis revealed that cognitive impairment was a feature in patients with Type 2a and Type 2b, but not in those with Type 1, and that importantly, Type 2b is a distinct subtype characterized by a poor prognosis despite the less severe loss of lower motor neurons, the unusual subcortical dendrospinal pTDP-43 pathology, and more prominent glial involvement in cortical pTDP-43 pathology than other two groups. Considering the patient survival time and severity of motor neuron loss in each group, transition from Type 1 to Type 2, or from Type 2a to Type 2b during the disease course appeared unlikely. Therefore, each of these three groups was regarded as an independent subtype.

    In this study we investigated the clinico-chemical parameters and the level of exposure of brick kiln workers to polycyclic aromatic hydrocarbons (PAHs) in Punjab (Pakistan). The brick kiln workers and a non-occupationally exposed group were recruited for comparative analysis of urinary biomarkers of PAH exposure (i.e. 1-hydroxypyrene (1-OHPyr), α-naphthol and β-naphthol) and blood level of superoxide dismutase (SOD), as a biomarker of oxidative stress and other hematologic parameters. Questionnaires were used to document information on socio-demographic characteristics of all the subjects. The analysis of urinary biomarkers showed higher median concentrations of 1-OHPyr, and α- and β-naphthols in brick kiln workers (1.53, 3.65 and 1.53 μmol/mol-Cr, respectively) than non-occupationally exposed group (0.62, 0.64 and 0.66 μmol/mol-Cr, respectively). The 1-OHPyr in brick kiln workers was above the occupational exposure level. Among the clinical parameters of brick kiln workers, hemoglobin (Hb) and red blood cells (RBCs) were very low and closely associate with 1-OHPyr and β-naphthol. Additionally, the white blood cells (WBCs) and superoxide dismutase (SOD) were also elevated in brick kiln workers, which suggested inflammatory symptoms and high oxidative stress. The results show that regardless of possibly being affected by the poor nutrition, the anemic state and hematological changes observed in brick kiln workers may be associated with their exposure to smoke present in the environment of brick kilns.

    Background: Tobacco-attributable mortality in India is estimated to be at least 10%. Tobacco cessation is more likely to avert millions of deaths before 2050 than prevention of tobacco use initiation. Objective: To describe the clinico-epidemiological profile of attendees of a tobacco cessation clinic in a teaching hospital in Bangalore city. Materials and Methods: A descriptive study of 189 attendees seen over 2 years in the Tobacco Cessation Clinic of a tertiary-care teaching hospital in Bangalore, with information on socio demographic characteristics, tobacco-use details, nicotine dependence, family/medical history, past quit attempts, baseline stage-of-change, and treatment initiated. Results: Only 5% were ‘walk-in’ patients; 98% of attendees were smokers; 97% were males. The mean (±SD) age of attendees was 48.0 (±14.0) years. Most participants were married (88%), and predominantly urban (69%). About 62% had completed at least 8 years of schooling. Two-thirds of smokers reported high levels of nicotine dependence (Fagerström score >5/10). About 43% of patients had attempted quitting earlier. Four-fifths (79%) of tobacco-users reported a family member using tobacco. Commonly documented comorbidities included: Chronic respiratory disease (44%), hypertension (23%), diabetes (12%), tuberculosis (9%), myocardial infarction (2%), stroke (1%), sexual dysfunction (1%) and cancer (0.5%). About 52% reported concomitant alcohol use. At baseline, patients’ motivational stage was: Precontemplation (14%), contemplation (48%), preparation/action (37%) and maintenance (1%). Treatment modalities started were: Counseling alone (41%), nicotine replacement therapy alone (NRT) (34%), medication alone (13%), and NRT+medication (12%). Conclusions: This is the first study of the baseline profile of patients attending a tobacco cessation clinic located within a chest medicine department in India. Important determinants of outcome have been captured for follow-up and

    Frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS) are types of major TDP-43 (43-kDa TAR DNA-binding protein) proteinopathy. Cortical TDP-43 pathology has been analyzed in detail in cases of FTLD-TDP, but is still unclear in cases of ALS. We attempted to clarify the cortical and subcortical TDP-43 pathology in Japanese cases of sporadic ALS (n = 96) using an antibody specific to phosphorylated TDP-43 (pTDP-43). The cases were divided into two groups: those without pTDP-43-positive neuronal cytoplasmic inclusions in the hippocampal dentate granule cells (Type 1, n = 63), and those with such inclusions (Type 2, n = 33). Furthermore, the Type 2 cases were divided into two subgroups based on semi-quantitative estimation of pTDP-43-positive dystrophic neurites (DNs) in the temporal neocortex: Type 2a (accompanied by no or few DNs, n = 22) and Type 2b (accompanied by abundant DNs, n = 11). Clinico-pathologic analysis revealed that cognitive impairment was a feature in patients with Type 2a and Type 2b, but not in those with Type 1, and that importantly, Type 2b is a distinct subtype characterized by a poor prognosis despite the less severe loss of lower motor neurons, the unusual subcortical dendrospinal pTDP-43 pathology, and more prominent glial involvement in cortical pTDP-43 pathology than other two groups. Considering the patient survival time and severity of motor neuron loss in each group, transition from Type 1 to Type 2, or from Type 2a to Type 2b during the disease course appeared unlikely. Therefore, each of these three groups was regarded as an independent subtype. PMID:27338935

    We investigated the clinico-biological features, outcomes, and prognosis of 949 patients with chronic lymphocytic leukemia according to age. No biological differences (cytogenetics by fluorescent in situ hybridization, IGHV, ZAP-70, CD38, NOTCH1, SF3B1) were found across age groups. Elderly patients (>70 years; n=367) presented more frequently with advanced disease (Binet C/Rai III-IV: 10/12% versus 5/5%; P<0.001), were treated less frequently (23.8% versus 41.9% at 3 years; P<0.001) and in most cases did not receive highly effective regimens and thus had a lower overall response rate (49% with 14% having complete responses versus 69% with 31% having complete responses; P<0.001). The elderly patients also had a shorter overall survival (6.6 versus 13.3 years; P<0.001) and higher disease-unrelated mortality (34.9% versus 6.9% at 10 years; P<0.001). However, disease-attributable mortality was not significantly different between younger and older patients. A combination of Binet stage, ZAP-70 level, β2-microglobulin concentration and comorbidity identified two risk groups (low-risk: 0-1 parameters; high-risk: 2-4 parameters) with different overall survivals (median: 6.8 versus 11.4 years, P<0.001). In patients requiring treatment, comorbidity at treatment (Cumulative Illness Rating Scale-T>4; hazard ratio 2.2, P<0.001) and response (treatment failure versus response: hazard ratio 1.60, P<0.04) were the most important prognostic factors for overall survival. In conclusion, in our series, elderly patients with chronic lymphocytic leukemia did not present with any biological features distinct from those of younger patients, but did have a poorer clinical outcome. This study highlights the importance of comprehensive medical care, achieving response to therapy, and specific management strategies for elderly patients with chronic lymphocytic leukemia.

    We examined the data of 24 patients with Henoch-Schönlein purpura nephritis (HSPN) over a 5-year follow-up period. Proteinuria, sediment RBC and CRP significantly decreased between the time of diagnosis and the end of the 5-year period. In the steroid usage group (n = 16), proteinuria was significantly higher, and crescent formation was significant higher at the time of diagnosis than in the non-steroid usage group (n = 8). However, there was no significant difference in the decrease in eGFR from the baseline at the end of the 5-year period between the two groups. Furthermore, to clarify the factors influencing the risk of renal function deterioration, we divided the patients into two groups, the (delta eGFR/pre eGFR) <0.25 group (n = 13) and (delta eGFR/pre eGFR) >0.25 group (n = 11), and compared the clinico-pathophysiological characteristics between the two groups. In the (delta eGFR/pre eGFR) >0.25 group, the ratio of glomerular obsolescence at the time of diagnosis was significantly higher than in the (delta eGFR/pre eGFR) <0.25 group. Glomerular obsolescence was identified as an independent risk factor for renal function deterioration. In this study, the prognosis of HSPN was related to glomerular obsolescence rather than to the disease activity. It may be necessary to consider the decrease in nephrons, in accordance with non-immunological glomerular obsolescence, in addition to immunological treatment to clarify the prognosis. PMID:20166542

    Background: Recent studies have indicated that although malignant cells at the invasive tumor front, bare morphological resemblance to the cells at central portion of the tumor, their molecular character differs significantly. E-cadherin is a cell-cell adhesion molecule that connects epithelial cells. This study attempts to correlate the E-cadherin expression at the invasive tumor front with tumor differentiation along with its clinico-pathological parameters. Materials and Methods: Immunohistochemical staining with E-cadherin was carried out on archival cases of primary oral squamous cell carcinomas (n = 30). The E-cadherin expression at the invasive tumor front was analyzed and was linked to clinico-pathological parameters including patient prognosis. Results: The downregulation of E-cadherin expression at the invasive tumor edge when compared with patient's prognosis yielded a significant correlation (P = 0.041) but its correlation with the degree of differentiation determined was not significant (P = 0.27). Also, its association with tumor size and lymph node status was negative. Conclusions: Loss of E-cadherin expression at the invasive tumor front is an important event in the progression of oral squamous cell carcinomas. Tumors with a loss of expression of E-cadherin are those which had a poor prognosis PMID:25328302

    Introduction: Renal cell carcinoma (RCC) represents about 3% of adult malignancies in Ireland. Worldwide there is a reported increasing incidence and recent studies report a stage migration towards smaller tumours. We assess the clinico-pathological features and survival of patients with RCC in a surgically treated cohort. Methods: A retrospective analysis of all nephrectomies carried out between 1995 and 2012 was carried out in an Irish tertiary referral university hospital. Data recorded included patient demographics, size of tumour, tumour-node-metastasis (TNM) classification, operative details and final pathology. The data were divided into 3 equal consecutive time periods for comparison purposes: Group 1 (1995–2000), Group 2 (2001–2006) and Group 3 (2007–2012). Survival data were verified with the National Cancer Registry of Ireland. Results: In total, 507 patients underwent nephrectomies in the study period. The median tumour size was 5.8 cm (range: 1.2–20 cm) and there was no statistical reduction in size observed over time (p = 0.477). A total of 142 (28%) RCCs were classified as pT1a, 111 (21.9%) were pT1b, 67 (13.2%) were pT2, 103 (20.3%) were pT3a, 75 (14.8%) were pT3b and 9 (1.8%) were pT4. There was no statistical T-stage migration observed (p = 0.213). There was a significant grade reduction over time (p = 0.017). There was significant differences noted in overall survival between the T-stages (p < 0.001), nuclear grades (p < 0.001) and histological subtypes (p = 0.022). Conclusion: There was a rising incidence in the number of nephrectomies over the study period. Despite previous reports, a stage migration was not evident; however, a grade reduction was apparent in this Irish surgical series. We can demonstrate that tumour stage, nuclear grade and histological subtype are significant prognosticators of relative survival in RCC. PMID:24839483

    Visceral Leishmaniasis (VL) is an endemic parasitic disease and remains as a major health concern in southwestern Iran. The current study describes clinico-hematological, epidemiological and therapeutic features of VL cases, admitted to university-affiliated hospitals, during 1999-2014 in Fars province, southwestern Iran. A total of 380 VL cases were recorded during a 16 years period, giving an average annual admission of 23.75 cases/year in which 217 (57.1%) were male and 163 (42.9%) were female. Mean age of the patients was 3.7 years. The majority of the cases (91.5%) were ≤ 5 years old. Bone-marrow aspiration detected Leishmania amastigotes only in 26.6% of cases. Fever (98.1%), abdominal protrusion (65.1%) and hepatosplenomegaly (63.7%) were the most common clinical presentations of the patients. Pancytopenia was noted in 43.1, anemia in 87.3 and thrombocytopenia in 64% of cases. Increase in the level of AST (aspartate aminotransferase), ALT (alanine aminotransferase), alkaline phosphatase, LDH (lactate dehydrogenase) and CRP (C-Reactive Proteins) were seen in 84.9, 53.6, 44.4, 72.5 and 83.1% of cases, respectively. Mortality was noted in 5.3% of cases. Deranged haemato-biochemical parameters including total and direct bilirubin, PLT (platelet) and pancytopenia were significantly contributed to mortality from VL. Moreover, clinical features such as severe splenomegaly as well as bacterial infections were meaningfully contributed to death from VL. The majority of patients (74.9%) were treated with meglumine antimoniate. Amphotericin B was administrated in 59 of cases, 11 of them were initially treated with meglumine antimoniate with a shift to amphotericin B, because of treatment failure. Findings of the current study demonstrated that VL is present in southwest of Iran with a fairly continual rate during the last 16 years period. Deranged haemato-biochemical parameters along with severe splenomegaly contributed to mortality from VL.

    The present paper reports results of a study to evaluate clinico-pathologically the effects of calcium hydroxide eugenol preparations on exposed pulp tissues in permanent human teeth. The experiments were performed on 80 vital human teeth from patients ranging in age from 12 to 54 years. The experimental teeth were arbitrarily divided into the following 4 groups. Group CRCS: 20 cases treated with CRCS (Hygienic, Akron, Ohio, USA). Group KEZ: 20 cases treated with Dentalis KEZ (Neo Dental Chemical Products, Tokyo, Japan). Group CE: 20 cases treated with calcium hydroxide eugenol (positive control) Group E: 20 cases treated with pure eugenol (negative control). After local anesthesia, the experimental teeth were isolated with rubber dums or cotton rolls. Following preparation of Black's simple class 1 cavities with a diamond instrument mounted high-speed air turbine, the pulp was intentionally exposed by means of a steel bur mounted electric engine. The cavity and exposed pulp surface were cleaned with saline and dried on absorbent material. Then the experimental materials (agents) were applied to exposed pulp surface. The cavity was lined with gutta-percha temporally stopping, and the remainder was filled with silver amalgam. The teeth were clinically observed at various intervals from immediately to 530 days after treatment and then extracted under local anesthesia and prepared for histopathological study. Decalcified sections were stained with hematoxylin and eosin. 1) CLINICAL OBSERVATIONS: During the observation period, symptoms occurred in the following: Group CRCS: 4 (20%) out of 20 cases. Group KEZ: 4 (20%) out of 20 cases. Group CE: 6 (30%) out of 20 cases. Group E: None of 20 cases No spontaneous pain was observed in these groups. 2) Clinical evaluations Group: CRCS: 16 cases (80%) were good, 3 cases (15%) were satisfactory, and 1 cases (5%) were failure. Group KEZ: 16 cases (80%) were good, 1 cases (5%) were satisfactory, and 3 cases (15%) were failure

    In childhood, central nervous system (CNS) presentations associated with antibodies to voltage-gated potassium channel (VGKC) complex include limbic encephalitis, status epilepticus, epileptic encephalopathy, and autistic regression. We report the cases of two individuals (a 6-year-old male and an 11-year-old female) who presented with an acute-onset explosive seizure disorder with positive VGKC complex antibodies and bilateral basal ganglia changes on magnetic resonance imaging (MRI). Both patients made a complete clinical recovery, without immunotherapy, with resolution of the MRI changes and normalization of the antibody levels. Extended antibody testing, including testing for leucine-rich glioma-inactivated 1 (LGI1), contactin-associated protein 2, and contactin-2 was negative. This could suggest that the clinico-radiological phenotype in our patients may in fact be associated with a novel autoreactive target(s) within the VGKC complex, as may be the case in other children with VGKC complex-mediated CNS disorders.

    Japanese encephalitis (JE) is a major public health problem in Asia and worldwide and it is responsible mainly for viral acute encephalitis syndrome (AES). The sole etiologic agent of JE is Japanese encephalitis virus (JEV). Although JE/AES cases have been regarded traditionally as a disease of children, a growing number of patients with JE/AES cases are also seen in the adult age group every year in the state of West Bengal, India in spite of vaccination. Therefore, a systematic study was performed to differentiate and characterize the clinico-pathological parameters and viral diversity among the patients of different age groups. Viral diversity was also evaluated from the JE/AES cases, depending on their disease severity. A total of 441 JE/AES cases were included in this study. By MAC-ELISA, 111 samples were found JEV IgM positive and among the IgM negative cases, 26 samples were found RT-PCR positive against JEV infection. Neck rigidity, abnormal behavior, convulsion, protein in CSF, WBC in CSF, and aspartate transaminase in blood differed significantly among the patients of pediatric-adolescent and adult group in both IgM positive and RT-PCR positive cases. Viral diversity was increased significantly in the pediatric-adolescent group compared to adult patients. Interestingly, with the rise in disease severity the viral diversity was found to be increased among the patients, irrespective of their age distribution. Based on clinico-pathological parameters and analysis of viral diversity, it can be concluded that viral diversity which occurs naturally is likely to affect disease severity, especially in the patients of pediatric-adolescent group.

Mejorar el conocimiento del perfil clinicorradiologico de esta enfermedad. Pacientes y metodos. Estudio retrospectivo con inclusion de pacientes menores de 14 años ingresados en un hospital terciario en los ultimos 15 años con el diagnostico de EAD. Se revisaron antecedentes, signos clinicos de presentacion, datos analiticos en sangre/liquido cefalorraquideo y la semiologia radiologica. En 16 casos se realizo un seguimiento medio de 25 meses. Resultados. Se revisaron 20 pacientes, un 70% niños, con una edad media de 4,4 años. El 40% tuvo un episodio febril previo. El 85% presento fiebre o vomitos, y el 70%, afectacion del estado de consciencia. Predominaron los deficits motores (45%), las convulsiones (35%) y la afectacion de pares craneales (30%). Tres niños presentaron una evolucion recidivante, y otros tres, secuelas motoras. Los estudios de resonancia magnetica mostraron lesiones hiperintensas en secuencias T2, con patron de realce escaso o nulo, que predominaron en los talamos (70%), la medula (67%) y la sustancia blanca subcortical (50%). En dos pacientes se diagnostico EAD hemorragica. Conclusiones. La EAD representa una entidad con importante afectacion general y repercusion neurologica, que muestra un potencial secuelar considerable. Los datos clinicoanaliticos y la resonancia magnetica cerebral y medular son relevantes para el diagnostico inicial y seguimiento de pacientes con EAD.

    Background To date, no direct scientific evidence has been found linking tissue changes in multiple sclerosis (MS) patients, such as demyelination, axonal destruction or gliosis, with either steady progression and/or stepwise accumulation of focal CNS lesions. Tissue changes such as reduction of the retinal nerve fiber layer (RNFL) and the total macular volume (TMV), or brain- and spinal cord atrophy indicates an irreversible stage of tissue destruction. Whether these changes are found in all MS patients, and if there is a correlation with clinical disease state, remains controversial. The objective of our study was to determine, whether there was any correlation between the RNFL or TMV of patients with MS, and: (1) the lesion load along the visual pathways, (2) the ratios and absolute concentrations of metabolites in the normal-appearing white matter (NAWM), (3) standard brain atrophy indices, (4) disease activity or (5) disease duration. Methods 28 MS patients (RRMS, n = 23; secondary progressive MS (SPMS), n = 5) with moderately-high disease activity or long disease course were included in the study. We utilised: (1) magnetic resonance imaging (MRI) and (2) -spectroscopy (MRS), both operating at 3 Tesla, and (3) high-resolution spectral domain-OCT with locked reference images and eye tracking mode) to undertake the study. Results There was no consistency in the pattern of CNS metabolites, brain atrophy indices and the RNFL/TMV between individuals, which ranged from normal to markedly-reduced levels. Furthermore, there was no strict correlation between CNS metabolites, lesions along the visual pathways, atrophy indices, RNFL, TMV, disease duration or disability. Conclusions Based on the findings of this study, we recommend that the concept of ‘clinico-radiologico paradox’ in multiple sclerosis be extended to CROP–‘clinico-radiologico-ophthalmological paradox’. Furthermore, OCT data of MS patients should be interpreted with caution. PMID:26565967

    Walter Cannon and Richard Cabot inaugurated the clinico-pathological conference (CPC) at Harvard Medical School at the beginning of the twentieth century, but this approach to anatomo-clinical correlation was first introduced by Giovanni Battista Morgagni at the University of Padua in the eighteenth century. The CPC consists of the presentation of a clinical case, in which past and recent medical histories of the patient, with all relevant information about laboratory tests including biopsy results, therapy and, eventually in a fatal case, the autopsy, are discussed. This is done for an audience of trainees and all physicians involved in the care for the patient. The CPC is still in use in many academic hospitals, as a teaching tool not only for undergraduate and graduate medical trainees, but also for postgraduate continuous medical education, in spite of the progressively declining autopsy rate. CPCs represent the ideal occasion for fruitful discussion between the two "souls" of medicine, i.e., the clinical, with its focus on the patient, and the pathological, with its focus on understanding disease. To discontinue using them would be equal to denying that modern medicine originated in Morgagni's method. PMID:25989714

    To study the main clinico-biological characteristics and the outcome of patients with diffuse large B-cell lymphoma (DLBCL) according to the primary site (nodal vs. extranodal), we included 262 patients consecutively diagnosed with DLBCL in a single institution, 5 years before and after immunochemotherapy was considered as the standard treatment. Altogether 116 patients received CHOP (cyclophosphamide, adriamycin, vincristine, and prednisone) and 146 rituximab plus CHOP (R-CHOP). The primary site was the lymph node in 140 patients (53%), Waldeyer's ring (WR) in 22, gastrointestinal (GI) in 33, and other extranodal in 67. The addition of rituximab significantly improved the CR rate in nodal, but not in extranodal, lymphomas. Patients receiving R-CHOP showed higher OS than those treated with CHOP alone (5-year OS: 71% vs. 48%). This difference was maintained in primary nodal (5-year OS: 69% vs. 37%, p < 0.0001), but was not observed in primary extranodal (75% vs. 65%, p = 0.45) lymphomas. The IPI, treatment, and primary site were the main variables for OS in multivariate analysis. In nodal cases, IPI and treatment maintained value, whereas only IPI predicted OS in extranodal cases. In conclusion, immunochemotherapy treatment dramatically improved the outcome of patients with nodal DLBCL; however, its effect was less in primary extranodal cases, so the prognosis of patients with nodal and extranodal lymphomas has been equalized in the rituximab era.

    Serous neoplasms (SN) of the pancreas account for 1-2% of all pancreatic tumours. Six morphological variants of SN were previously recognized: serous microcystic (cyst)adenoma, serous macrocystic (cyst)adenoma, von Hippel-Lindau-associated serous cystic neoplasm, solid serous adenoma/neoplasm, mixed serous-neuroendocrine neoplasm and serous cystadenocarcinoma. It was recently postulated that SN shows a continuous spectrum of morphological patterns rather than distinct clinico-pathological subtypes. To address this issue, we performed a detailed review of 40 SN cases diagnosed at our institution between 1989 and 2011. We found 11 cases of serous microcystic (cyst)adenoma, 5 cases of serous macrocystic (cyst)adenoma, and a single case of von Hippel-Lindau-associated serous cystic neoplasm. Apart from that, we found 20 cases of SN which showed features of both microcystic and macrocystic (cyst)adenomas, 2 cases of small 'incipient' SN and a single case of a mixed microcystic and solid adenoma. In conclusion, we showed that 'borderline' lesions among SNs truly exist and are not rare. The reason for such a wide diversity of morphological patterns of SN remains unknown.

    Objectives: This study was primarily designed to determine the clinico-radiographic efficacy of platelet-rich fibrin (PRF) and beta-tri-calcium phosphate with collagen (β-TCP-Cl) in preserving extraction sockets. Materials and Methods: For Group I (PRF), residual sockets (n = 15) were filled with autologous PRF obtained from patients' blood; and for Group II (β-TCP-Cl), residual sockets (n = 15) were filled with β-TCP-Cl. For the sockets randomly selected for Group II (β-TCP-Cl), the reshaped Resorbable Tissue Replacement cone was inserted into the socket. Results: Clinically, there was a significantly greater decrease in relative socket depth, but apposition in midcrestal height in Group II (β-TCP-Cl) as compared to Group I (PRF), whereas more decrease in buccolingual width of Group I (PRF) than Group II (β-TCP-Cl) after 6 months. Radiographically, the mean difference in socket height, residual ridge, and width (coronal, middle, and apical third of socket) after 6 months was higher in Group I (PRF) as compared to Group II (β-TCP-Cl). The mean density (in Hounsfield Units) at coronal, middle, and apical third of socket was higher in Group I (PRF) as compared to Group II (β-TCP-Cl). There were statistically significant apposition and resorption for Group I (PRF) whereas nonsignificant resorption and significant apposition for Group II (β-TCP-Cl) in buccal and lingual/palatal cortical plate, respectively, at 6 months on computerized tomography scan. Conclusion: The use of either autologous PRF or β-TCP-Cl was effective in socket preservation. Results obtained from PRF were almost similar to β-TCP-Cl; therefore being autologous, nonimmune, cost-effective, easily procurable regenerative biomaterial, PRF proves to be an insight into the future biofuel for regeneration.

    Background and Objective: Dengue, an acute viral disease, transmitted by Aedes mosquitoes, has a variable clinical spectrum ranging from asymptomatic infection to life-threatening dengue hemorrhagic fever and dengue shock syndrome. However, neurological complications, in general, are unusual but have been observed more frequently in the recent past, and some studies highlighted varied neurological complications during the course of illness. Although dengue is classically considered a nonneurotropic virus, there is increasing evidence for dengue viral neurotropism. In this study, we have evaluated clinico-radiological profile and outcome of nine serologically confirmed dengue patients having varied manifestations of central nervous system (CNS) involvement. Materials and Methods: All the consecutive patients presented with neurological complications with positive serology for dengue infection (IgM positivity) in Department of Medicine, in a tertiary care hospital in Eastern India from August 2013 to October 2014 were included in the study. These patients were subjected to a detailed clinical evaluation, laboratory assessment including complete hemogram, coagulation profile, liver function test, serum electrolytes, and routine CSF (Cerebrospinal Fluid) study with the exclusion of other common neuroinvasive pathogens. Results: Out of 9 patients with neurological complications associated with confirmed dengue infection, 2 (22%) patients had dengue encephalopathy, 5 (56%) patients have dengue encephalitis, 1 (11%) patient had dengue meningitis, and 1 (11%) patient had postdengue immune-mediated CNS involvement. Conclusion: This case series reaffirms the occurrence of varied CNS manifestations in dengue virus infection and underlines the importance of inclusion of dengue in the differential diagnosis of acute encephalitis syndrome.

    The outcome of children and adults with acute lymphoblastic leukemia is markedly different. Since there is limited information on the distribution of clinico-biological variables in different age cohorts, we analyzed 5202 patients with acute lymphoblastic leukemia enrolled in the Italian multicenter AIEOP and GIMEMA protocols and stratified them in nine age cohorts. The highest prevalence of acute lymphoblastic leukemia was observed in children, although a second peak was recorded from the 4th decade onwards. Interestingly, the lowest incidence was found in females between 14–40 years. Immunophenotypic characterization showed a B-lineage in 85.8% of patients: a pro-B stage, associated with MLL/AF4 positivity, was more frequent in patients between 10–50 years. T-lineage leukemia (14.2%) was rare among small children and increased in patients aged 10–40 years. The prevalence of the BCR/ABL1 rearrangement increased progressively with age starting from the cohort of patients 10–14 years old and was present in 52.7% of cases in the 6th decade. Similarly, the MLL/AF4 rearrangement constantly increased up to the 5th decade, while the ETV6/RUNX1 rearrangement disappeared from the age of 30 onwards. This study shows that acute lymphoblastic leukemia in adolescents and young adults is characterized by a male prevalence, higher percentage of T-lineage cases, an increase of poor prognostic molecular markers with aging compared to cases in children, and conclusively quantified the progressive increase of BCR/ABL+ cases with age, which are potentially manageable by targeted therapies.

    2012-01-01

    Background Human cutaneous anthrax results from skin exposure to B. anthracis, primarily due to occupational exposure. Bangladesh has experienced a number of outbreaks of cutaneous anthrax in recent years. The last episode occurred from April to August, 2011 and created mass havoc due to its dreadful clinical outcome and socio-cultural consequences. We report here the clinico-demographic profile and treatment outcome of 15 cutaneous anthrax cases attended at the Dermatology Outpatient Department of Rajshahi Medical College Hospital, Bangladesh between April and August, 2011 with an aim to create awareness for early case detection and management. Findings Anthrax was suspected primarily based on cutaneous manifestations of typical non-tender ulcer with black eschar, with or without oedema, and a history of butchering, or dressing/washing of cattle/goat or their meat. Diagnosis was established by demonstration of large gram-positive rods, typically resembling B. anthracis under light microscope where possible and also by ascertaining therapeutic success. The mean age of cases was 21.4 years (ranging from 3 to 46 years), 7 (46.7%) being males and 8 (53.3%) females. The majority of cases were from lower middle socioeconomic status. Types of exposures included butchering (20%), contact with raw meat (46.7%), and live animals (33.3%). Malignant pustule was present in upper extremity, both extremities, face, and trunk at frequencies of 11 (73.3%), 2 (13.3%), 1 (6.7%) and 1 (6.7%) respectively. Eight (53.3%) patients presented with fever, 7 (46.7%) had localized oedema and 5 (33.3%) had regional lymphadenopathy. Anthrax was confirmed in 13 (86.7%) cases by demonstration of gram-positive rods. All cases were cured with 2 months oral ciprofloxacin combined with flucoxacillin for 2 weeks. Conclusions We present the findings from this series of cases to reinforce the criteria for clinical diagnosis and to urge prompt therapeutic measures to treat cutaneous anthrax

    We reviewed the clinico-pathological features of a series of 13 cases of benign spindle stromal tumors (BSSTs) of the breast relating to a basic common theme consisting of a well-circumscribed proliferation of vimentin+/CD34+/BCL-2+/CD99+ spindly to oval-epithelioid cells, variably arranged in haphazard to short fascicular growth pattern, with interspersed thick or thin collagen bands. Morphological variations included atypical mono- or multi-nucleated cells in five cases and a mature lipomatous tumor component, varying from focal to prominent, in eight cases. Based on morphological and immunophenotypical features, a distinction was made between two main subtypes of these tumors--fibroblastic and myofibroblastic. The former subtype included two cases respectively represented by a typical solitary fibrous tumor (SFT) and a neoplasm labeled "spindle-cell lipoma (SCL)-like tumor", closely reminiscent of soft tissue SCL. Both tumors had cells with fibroblastic-like appearance, haphazardly arranged and immunoreactive for vimentin, CD34, BCL-2, and CD99. The latter subtype, comprised nine cases exhibiting evidence of myofibroblastic differentiation (desmin and alpha-smooth muscle actin) which were classified as myofibroblastomas (MFBs). The remaining two cases were defined as "mixed BSSTs", having typical features of diverse neoplasms, respectively represented by a case of MFB with focal SFT and pleomorphic/SCL-like areas, and SFT with focal MFB-like component. The common basic morpho-immunophenotypical features, the possibility that both fibroblastic and myofibroblastic tumors may contain an additional mature lipomatous component, and the existence of hybrid stages (mixed BSSTs) strongly support the view that such tumors belong to the same category of lesions. We postulate that the precursor of all these neoplasms is the vimentin+/CD34+ cells of the mammary stroma, the well-known inherent plasticity of which to differentiate toward several mesenchymal lines, provides

    We present a clinical and histopathological study of 25 mucoceles of the oral cavity. Incidence was found to be greatest between age 10 and 20 (12 cases), with no significant differences in terms of sex. The lower lip was most frequently affected (17 cases), other locations being much less common. In 72% of cases there were etiological antecedents of traumatism. Mucocele size varied from 3 to 13 mm. although a great many of them were between 10 and 13 mm. Evolution period was 1-16 months, incidence being highest between 1 and 4 months. Finally, histology showed 95% to be due extravasation, the remaining 5% being the result of retention. Among the extravasation mucoceles, 11.7% were in the initial phase, another 11.7% in the reabsorption stage, and 76.4% in the final phase. PMID:2094260

    The Hamburg sexual counseling unit has been working since 1979 as a model project of the Federal Ministry of Youth, Family and Health. The therapeutic work done by the unit is based on the concept originally worked out by Master and Johnson, which was modified at the Department of Sex Research at Hamburg University in such a manner that it is both helpful and feasible as a treatment pattern for patients coming from all social classes. Basing on sexual symptoms, a problem definition is worked out which aims at underlining the subjective importance for the patient of the symptom concerned. The important factor is the ratio of stabilizing and destabilizing elements of a disturbance, in other words, the question as to the function of the sexual disturbance in the psychic or partnership balance either in the sense of rejecting desires for change or of reinforcing the "healthy" components of the symptom in the sense of prompting a motivation for change. In this regard, therapy is considered as one of many possibilities of effecting a change. Particularly successful has been the employment of couple therapy and group therapy for couples and for women.

Si tratta di uno studio prospettico randomizzato eseguito su 243 pazienti: 123 sottoposti alla procedura laparotomica CMNF e 120 pazienti trattati con la fundoplicatio totale laparoscopica. Gli esami pre- e postoperatori comprendono l’endoscopia, lo studio radiologico, un questionario da sottoporre al paziente (secondo lo schema GERD-HQRL) e lo studio clinico. Tutti i paziente sono stati controllati per un follow-up di 10 anni. Questo trial prospettico randomizzato ha mostrato risultati a lungo termine rispettivamente buoni ed eccellenti dopo chirurgia laparotomica e laparoscopica per GERD (92,7% vs 88,5% rispettivamente) (p=0,03). Dopo CMNF laparotomica si sono verificati tre casi di laparocele e 9 casi di modica disfagia. In nessun caso di è registrata una recidiva. Dopo approccio laparoscopico si sono osservati 7 casi di disfagia transitoria per i solidi, 3 casi di stenosi grave a livello cardiaco in rapporto alla plicatura. Vi sono stati due casi di recidiva, 3 casi di reflusso ed 1 caso di ernia epigastrica a livello del foro del trocar. Come nel resto del mondo, attualmente in Georgia la fundoplicatio totale per via laparoscopica rappresenta il metodo preferito di scelta per il trattamento della GERD. Esso presenta i migliori risultati estetici, il minor dolore ed i minori problemi a livello delle ferite, un più breve ricovero e un più precoce ritorno all’attività. Anche la procedura CMNF laparotomica è efficace e sicura. In essa si previene la sindrome da scivolamento ed è caratterizzata da un migliore controllo del reflusso ed

    We report clinical, radiological, and pathological features of three cases of macrodystrophia lipomatosa, which is characterized by progressive proliferation of all mesenchymal elements, with a disproportionate increase in fibroadipose tissue. The peculiarity in our report is the involvement of contralateral hand and feet in our 1st case in contrast to usual presentations of this rare condition, which is often unilateral. In our 2nd case, the lateral aspect of foot was involved as against the usual finding of involvement of medial aspect in lower limbs, also another surprising finding in this case is increase in the size of lesion after puberty. Coming to our 3rd case, enlargement of almost whole of an upper extremity with profound involvement of middle, ring and little finger along with total sparing of the thumb is in itself an extremely rare occurrence as in upper limb, mainly the lateral aspect of hand and related digits bear the burnt and more over involvement of whole limb is itself an unique phenomenon.

The historical significance and current epidemiology of typhus, including the reservoir of Rickettsia prowazekii in flying squirrels in the United States, are reviewed, and the clinical presentation, laboratory findings, and hospital course in the cases of 60 patients admitted with epidemic, louse-borne typhus to the St. Paul's Hospital in Addis Ababa, Ethiopia, are described. Treatment of this disease with oral doxycycline, tetracycline, or chloramphenicol prevents complications and results in prompt resolution of symptoms. PMID:1600020

    Oral exophytic lesions often have proven to be diagnostically challenging due to the varied clinical presentation. The exophytic growth of the oral lesions is due to the type of pathology and histological changes. Careful clinical interpretation with a better histological understanding of exophytic lesions may ease the diagnosis from the differential diagnosis panel. The purpose of proposing classification system is to categorize the exophytic lesions of interest under specific clinical and/or histological explanation; and this will eventually lead to better understanding of the pathological condition that is described. To the best of our knowledge, there is no such classification system available for oral exophytic lesions and hence proposal of classification system is attempted in this study. Further, proposing a new classification system is not just to influence the academic contribution, but also to assist at greatest extent for diagnosis during clinical practice. PMID:26501030

    Background: Odontomas are among the most common benign odontogenic tumors, which are mostly discovered in the first and second decades of life with no clear sex predilection. Materials and Methods: The present retrospective study reviews the clinical, radiological, and the histopathological characteristics of odontomas in 19 Libyan patients seen during the last 18 years in our department. Results: Most odontomas in our study were discovered when they obstruct a tooth from an eruption at its normal eruption time although a few cases were noticed on routine radiological examination of the region. Panoramic radiographs computed Tomography Scan of the area and the histopathological examination are helpful to elicit the diagnosis. Two cases in this series were found associating with dentigerous cyst and in another two cases the odontomas were seen erupting intraorally. Conclusion: Odontomas should be considered in the differential diagnosis of the mixed radioopaque radiolucent lesions, especially if they found obstructing the teeth from eruption. PMID:24348614

    1996-05-01

    Patients with spontaneous neck pain, headache, dizziness and/or pain to the upper limbs are frequently observed. Common cervicodynia, due to the involvement of arthromuscular structures of the cervical spine, was diagnosed in the patients with these symptoms in the absence of trauma or neurologic signs. The authors investigated the clinical-radiologic correlation in a series of 130 symptomatic patients and considered it a metameric disorder. The frequent association of many radiographic signs at the same level often prevents single radiographic signs from being assessed individually; therefore, the authors selected some patients with just one radiographic change per functional unit, to assess its relationship with clinical symptoms. The patients underwent anteroposterior, lateral and functional (flexion-extension) radiographs of the cervical spine. Vertebral rotation, detected on antero-posterior views as a spinous process deviation, was the most frequent isolated sign (79/130 cases) per metameric level, with strong clinical correlation (70/79 cases). Vertebral rotation was probably due to unilateral muscular stiffness. Other single radiologic signs per functional unit with strong clinical correlation follow: atloaxial rotation (13/130 with clinical-radiologic agreement of 12/13), functional blockage (13/130 with clinical-radiologic agreement of 11/13), angular flexion (21/130 with clinical-radiologic agreement of 19/21) and overall disc space thinning (12/130 with clinical-radiologic agreement of 10/12). Atloaxial rotation is represented as an asymmetry of the spaces between the odontoid and the lateral masses of the atlas; functional blockage consists of insufficient or lacking physiological width of the occipito-atlantoid or interspinous space in functional tests. Angular flexion consists of a single flexion angle of the cervical spine in functional tests; two or more angles indicate normal flexion of the cervical spine. This study confirmed the poorer clinical impact of degenerative changes, mostly interapophyseal arthrosis, than of other radiologic signs. Interapophyseal arthrosis alone was isolated in single functional units in 46/130 patients, mostly at C7-D1, with clinical-radiologic agreement in 19/46 patients. Clinical-radiologic correlation proved the high diagnostic value of anteroposterior, lateral and functional radiographs of the cervical spine in common cervicodynia, which make them a valuable tool for the clinician.

    Context: Nummular headache (NH) is a primary disorder characterized by head pain exclusively felt in a small-rounded area typically 2–6 cm in diameter. Aims: The aim of this review is to study the clinical and epidemiological features of NH in a patient population of South India and to compare this with that of described in the international literature. Settings and Design: A prospective, observational study conducted in a tertiary care center. Materials and Methods: Patients attending the medicine and neurology outpatient departments of a tertiary referral hospital in South India diagnosed to have NH as per the International Classification of Headache Disorders 3 beta (2013) criteria were studied over 30 months. All of the patients had a normal neurological examination. Neuroimaging findings were normal, except in one patient. Results: A total of 19 females and 10 males were studied. The mean age of onset was 47.62 years (range 36–60). The duration of headache varied from a minimum of 3 months to a maximum of 5 years, with a mean of 24.17 months. The site of headache was predominantly in the parietal area 15 (51.72%), followed by the occipital area 7 (24.13%). The mean diameter of the affected area was 3.23 cm. The intensity of the headache proved to be mild to moderate with a mean visual analog scale score of 5.03. The quality of pain was mainly felt as burning dysesthesia 12 (41.38%). In the majority of patients, i.e. 21 (72.41%), pain was chronic and continuous. None of the patients had any significant trophic change even though paresthesias, dysesthesias, and allodynia were reported by a significant minority of patients, i.e. 9 (31.03%). Only one (3.45%) patient gave a history of head injury. Ten (34.48%) out of 29 patients had other types of concurrent headaches; the majority of which proved to be migrainous, i.e. 7 (24.14%), 2 patients (6.89%) with tension headache, and 1 patient (3.45%) with trigeminal neuralgia. Conclusion: Our study proves the existence of the newly described primary headache syndrome called NH in South Indian population. In comparing our results with the international literature, the number of similarities is much greater than the differences. The etiology of pain in our series appeared to be primarily peripheral with a role for central pain sensitization in some cases due to a variety of concurrent central causes of head pain.

    Rapid advances in molecular technologies are continually re-shaping the way we view and understand the mechanisms driving oncogenesis. The last decade has witnessed unparalleled change in the biology and therapy of the myelodysplastic syndromes (MDS), a heterogeneous collection of clonal myeloid disorders characterised by ineffective haematopoiesis and susceptibility to acute leukaemia transformation. Pivotal studies demonstrating the positive effects of hypomethylating agents on clinical outcome have brought an 'epigenomics revolution' to this disease, emphasising the importance of epigenetic mechanisms to the underlying pathogenesis of MDS. One of the most important future challenges in the MDS field will be to determine whether epigenetic therapies can be made more 'targeted' through identification of biomarkers which define subsets of patients most likely to benefit from treatment. A wave of novel mutations have recently been reported in MDS and other myeloid disorders, several of which regulate endogenous methylation networks within cells (including TET2, DNMT3A, IDH and EZH2). The relevance of these lesions in being able to predict response to epigenetic modulators and their correlation with epigenetic signatures in MDS are beginning to emerge.

    18 patients with "primary empty sella" were reviewed for this study. In 3 of them the sellar enlargement was discovered occasionally by performing skull radiographs for other reasons. The galattorrhea-dismenorrhea or amenorrhea syndrome and obesity were the most common clinical features. Endocrinological tests were normal in ten patients and abnormal in eight. Slight elevation of serum PRL was the most common record. 12 patients had enlarging of the sella turcica; in 4, only the floor was asymmetric and in 2 the sella was quite normal. In 5 patients C.T. without intra-thecal contrast was sufficient to discover the E.S. In 13 patients we performed C.T. cysternography by injecting in the lumbar subarachnoid space 8-10 ml of Iopamidolo 200. This is an excellent and safe technique to perform C.T. cysternography.

    During the course of the smallpox eradication programme, a new eruptive disease clinically resembling smallpox was discovered in Zaire. The disease, which was named monkeypox after the virus, is a zoonosis occurring sporadically in countries of western and central Africa with tropical rain forest. The studies carried out in Zaire from 1980 through 1985 showed that monkeypox affects mainly children in relatively small remote villages whose population has traditionally frequent contacts with wild animals. Apart from the wildlife, the virus can be transmitted from man to man, but among other sources of infection sick persons did not exceed 20%. Presumed human transmission has occurred in 38 out of 61 outbreaks of human monkeypox and only once reached the third and once the fourth generation; the transmission in all affected villages under observation has extinguished itself. Considering the sporadic and relatively rare occurrence of the disease and expected complications following the immunization with vaccinia which protects from monkeypox, introduction of mass vaccination in the areas at risk is hardly justified at present.

    1986-08-01

    A series of 22 cases of unilateral condylar hyperplasia is presented with the emphasis on histopathological aspects. It is concluded that there are two types of condylar hyperplasia. The first manifests itself in the adolescent or the young adult and represents an exaggerated, normally proceeding growth and maturation process. The histological structure of the condyle in these cases is age-dependent as is shown by a conversion of hyaline growth cartilage into fibrocartilage occurring at about 20 years of age. The second type of condylar hyperplasia, seen in older people, probably represents reactive growth as a response to an eliciting agent that mostly can be identified. In these cases the histological architecture of the condyle is distorted by large masses of hyaline cartilage while there are concomitant degenerative changes in the form of arthrosis. In contrast to the patients suffering from the first type of condylar hyperplasia, the latter ones complain of additional joint symptoms, mostly pain. Moreover it is concluded that joint scintigraphy does not clearly discriminate between genuine condylar hyperplasia and reactive processes due to arthrosis, which may have clinical implications.

    Solitary trichoepithelioma of the eyelid is a very rare tumor, which needs to be differentiated from basaloid epithelioma and basal cell carcinoma. Diagnosis is based on clinical and histopathological examination. We present a case of an eyelid trichoepithelioma presenting as a long standing nodule with associated dermatochalasis. Although rare, this entity should be kept in the differential diagnosis of chronic, firm, nodular eyelid lesions. PMID:26180455

    A case of primary brainstem death in a man with surgically treated cerebellar haemorrhage is reported. Necropsy revealed extensive necrosis confined to the brainstem and cerebellum. The absence of diabetes insipidus and the persistence of electroencephalographic activity were the characteristic clinical features of the case. This differentiates the condition from so-called "whole brain death". Analysis of three further cases with acute vascular lesions of the brainstem or cerebellum, shown at necropsy, revealed that primary brainstem death with prolonged somatic survival can occur in specific circumstances after surgical intervension.

    Intestinal disorders in infants are determined in 96.9% of cases by the opportunistic flora with the predominance of Pr. mirabilis (25.5%), E. coli (19.1%), Enterobacter aerogenes (12.6%) and with the less frequent occurrence of Klebsiella (4.1%) and pathogenic staphylococci (5.8%). As a result of the unbased use of antibiotics, the majority of children demonstrate dysbacteriosis and the growth of the number of resistant hospital strains. It is suggested that in children with ARVI, the drugs containing lactic acid bacteria and lactose should be used on a wider basis to prevent dysbacteriosis and reduction of resistant strains.

    Psychopathologic and nosologic issues of acute paranoid and Kandinsky-Clerambault syndromes are discussed on the background of clinical studies of 225 schizophrenic patients with these syndromes being initial manifestations. The data on the syndromes typology, clinical value and prognosis of acute delirious disorders are presented. These are shown to be not confined to progredient schizophrenia, including its paranoid form. Rather, they can manifest a course of the disease unspecific for schizophrenia, the so-called schizophrenic reactions and phasic states thus reflecting the course of latent schizophrenia. A differentiated approach to clinical and psychopathological analysis of acute delirious syndromes in schizophrenia is essential for adequate choice of medicosocial measures and epidemiologic investigations.

    2015-09-01

    Oral exophytic lesions often have proven to be diagnostically challenging due to the varied clinical presentation. The exophytic growth of the oral lesions is due to the type of pathology and histological changes. Careful clinical interpretation with a better histological understanding of exophytic lesions may ease the diagnosis from the differential diagnosis panel. The purpose of proposing classification system is to categorize the exophytic lesions of interest under specific clinical and/or histological explanation; and this will eventually lead to better understanding of the pathological condition that is described. To the best of our knowledge, there is no such classification system available for oral exophytic lesions and hence proposal of classification system is attempted in this study. Further, proposing a new classification system is not just to influence the academic contribution, but also to assist at greatest extent for diagnosis during clinical practice. PMID:26501030

    Rescuer burn is a relatively newer terminology introduced to define the burns sustained by a person attempting to rescue a primary burn victim. Few studies have been published thus far on this peculiar type of burns. Due to the general neglect of the rescuer burns victim and discontinuation of treatment in most cases, once the primary victim dies, the rescuer often ends up in badly infected wounds and has a delayed return to work. A prospective study was conducted at the B J Medical College and Civil Hospital, Ahmedabad from January 2009 to December 2012 on the rescuer burns patients treated in its burns and plastic surgery department. 3074 patients of burns received treatment during the period of study. Of these, 48 patients gave the history of sustaining burns while trying to rescue a burns victim. Male to female ratio of rescuers was approximately 7:1. It was significantly higher as compared to the ratio of 1:0.8 of females to male burn victims observed at our centre (p≤0.01). Average age of the rescuers was higher in males as compared to females but the difference was not significant (p≥0.05). Of the 45 cases of female primary burns victims, male rescuer was husband of the primary victim in 41/45 cases (91.1%), mother was rescuer in three cases (6.6% cases) and sister was rescuer in one case. Though multiple people came to rescue a burns victim, in all cases, it was seen that it was the first rescuer who sustained burns himself or herself. None of the rescuers had any knowledge of the techniques and precautions to be taken while performing a rescue operation irrespective of their education status, indirectly pointing to the lack of any teaching on burns rescue in the school education curriculum.

    The results of clinical and x-ray investigations of 398 patients with disseminated pulmonary lesions were analyzed. Two groups were identified: patients with interstitial type of lesions (101) and patients with focal type of lesions (297). Proceeding from roentgeno-morphological correlations, the authors presented specified roentgeno-semiotics of 10 nosological entities with the syndrome of pulmonary dissemination. The possibilities of optimization of differential diagnosis of disseminated pulmonary lesions were shown basing on combined (clinical, functional and roentgenological) investigation.

    Context: Nummular headache (NH) is a primary disorder characterized by head pain exclusively felt in a small-rounded area typically 2–6 cm in diameter. Aims: The aim of this review is to study the clinical and epidemiological features of NH in a patient population of South India and to compare this with that of described in the international literature. Settings and Design: A prospective, observational study conducted in a tertiary care center. Materials and Methods: Patients attending the medicine and neurology outpatient departments of a tertiary referral hospital in South India diagnosed to have NH as per the International Classification of Headache Disorders 3 beta (2013) criteria were studied over 30 months. All of the patients had a normal neurological examination. Neuroimaging findings were normal, except in one patient. Results: A total of 19 females and 10 males were studied. The mean age of onset was 47.62 years (range 36–60). The duration of headache varied from a minimum of 3 months to a maximum of 5 years, with a mean of 24.17 months. The site of headache was predominantly in the parietal area 15 (51.72%), followed by the occipital area 7 (24.13%). The mean diameter of the affected area was 3.23 cm. The intensity of the headache proved to be mild to moderate with a mean visual analog scale score of 5.03. The quality of pain was mainly felt as burning dysesthesia 12 (41.38%). In the majority of patients, i.e. 21 (72.41%), pain was chronic and continuous. None of the patients had any significant trophic change even though paresthesias, dysesthesias, and allodynia were reported by a significant minority of patients, i.e. 9 (31.03%). Only one (3.45%) patient gave a history of head injury. Ten (34.48%) out of 29 patients had other types of concurrent headaches; the majority of which proved to be migrainous, i.e. 7 (24.14%), 2 patients (6.89%) with tension headache, and 1 patient (3.45%) with trigeminal neuralgia. Conclusion: Our study proves the existence of the newly described primary headache syndrome called NH in South Indian population. In comparing our results with the international literature, the number of similarities is much greater than the differences. The etiology of pain in our series appeared to be primarily peripheral with a role for central pain sensitization in some cases due to a variety of concurrent central causes of head pain.

    Background: The spectrum of pyoderma changes constantly, and so does the antibiotic susceptibility pattern. Aims: This study was done to assess the magnitude and clinical patterns of pyodermas, their causative micro-organisms, and the antibiotic susceptibility patterns. Materials and Methods: Five hundred consecutive, clinically diagnosed and untreated cases of pyoderma, attending the Dermatology OPD of RNT Medical College and MB Government Hospital, Udaipur, from October 2010 to September 2011 were the subjects of this study. A detailed clinical examination, and relevant investigations including bacterial culture and sensitivity, were carried out and recorded. Statistical Analysis: For statistical analysis of data, the software ‘EPI-INFO Version 6’ was used, and Chi-square (χ2) test was applied. Results: Of 19576 cases attending skin OPD during the study period, pyoderma was seen in 500 patients; the incidence being 2.55%. Males outnumbered females. The highest number of cases (109; 21.8%) was observed in 1st decade. Lower extremities were the commonest site of predilection. Primary pyodermas outnumbered secondary pyodermas. Furuncle (136; 27.2%) and infectious eczematoid dermatitis (62; 12.4%) were the commonest entities among primary and secondary pyoderma respectively. Staphylococcus aureus was the commonest causative agent in both primary and secondary pyoderma. It showed high susceptibility to amoxycillin + sulbactam, aminoglycosides and cefoperazone, moderate susceptibility to linezolid, while low susceptibility to fluoroquinolones and cephalexin. Conclusion: Such studies help to assess the changing trend of bacterial infections, their causative organisms and antibiotic susceptibility pattern. PMID:26538696

    Helicobacter pylori is a spiral Gram-negative bacterium with a relatively small genome and is known to be the most common human bacterial infection worldwide, infecting about half of the world's population. The bacterium represents one of the most successful human pathogens, inducing severe clinical symptoms only in a small subset of individuals, thus signifying a highly balanced degree of co-evolution of H. pylori and humans. The prevalence of Helicobacter pylori infection varies greatly among countries and among population groups within the same country, but is falling in most developed countries. The clinical course of H. pylori infection is highly variable and is influenced by both microbial and host factors including genetic susceptibility while the pattern and distribution of inflammation correlate strongly with the risk of clinical sequelae, namely duodenal or gastric ulcers, mucosal atrophy, gastric carcinoma, or gastric lymphoma. Cytokine gene polymorphisms directly influence inter-individual variation in the magnitude of cytokine response, and this clearly contributes to an individual's ultimate clinical outcome. Polymorphisms in genes coding for innate immune factors have also been incriminated in the pathogenesis of H. pylori related disease, while promoter hypermethylation of tumor suppressor genes is considered an important factor in carcinogenesis and known to be present in H. pylori associated gastric tumors. Functional genomics may fill many of the gaps in our understanding of the pathogenesis of H. pylori infection and accelerate the development of novel therapies, including H. pylori specific antimicrobial agents.

    Pulmonary alveolar microlithiasis (PAM) is a rare chronic lung disease characterized by deposition of intra alveolar calcium and phosphate in bilateral lung parenchyma with predominance in lower and mid zones. Etiology and pathogenesis is not fully understood. However, mutation in SLC34A2 gene that encodes a sodium phosphate co-transporter in alveolar type-II cells resulting in formation and accumulation of microliths rich in calcium phosphate due to impaired clearance is considered the cause of disease. Patients with PAM are asymptomatic till development of hypoxemia and cor pulmonale. It remains static, while in some it progresses to pulmonary fibrosis, respiratory failure and cor pulmonale. We report a case of 44 year old male patient presenting with progressive shortness of breath on exertion for one year in duration with dry cough, more since last six months. Chest radiograph showed dense micronodular opacities giving classical sandstorm appearance. High resolution computed tomography (HRCT) showed microcalcification, subpleural cystic changes and calcified pleura. Lung biopsy showed calcospherites within alveolar spaces. PMID:27200151

    Context: The dermatophytoses constitute a group of superficial fungal infections of keratinized tissues, namely, the epidermis, hair, and nails. The distribution and frequency of dermatophytosis and their etiologic agents vary according to the geographic region studied, the socio-economic level of the population, the time of study, the climatic variations, the presence of domestic animals, and age. Aims: The present study was undertaken to assess the clinical profile of dermatophytic infections and to identify the causative fungal species in the various clinical presentations. Settings and Design: This was a hospital-based observational study. Materials and Methods: One hundred and fifty clinically suspected cases of dermatophytosis attending the outpatient department of a tertiary care hospital were included in the study. History was taken, general physical and cutaneous examination was done and details of skin lesions noted. Direct microscopy in 10% KOH (40% KOH for nail) and fungal culture on SDA with 0.05% chloramphenicol and 0.5% cycloheximide was done in every case. Statistical Analysis Used: Statistical analysis was done using SPSS 17.0 software. Chi-square test and contingency coefficient test were used as significant tests for analysis. Results: Out of 150 patients studied, majority belonged to the age group of 21–30 years (22.7%). Male-to-female ratio was 1.63:1. Tinea corporis (24.7%) was the most common clinical type observed. The overall positivity by culture was 40% and by direct microscopy was 59.3%. Trichophyton mentagrophytes was the predominant species isolated (48.3%). Conclusions: The present study reveals the changing trend in the prevalence of dermatophyte species in this part of Karnataka. PMID:27559499

    Pyodermas are a common group of infectious dermatological conditions on which few studies have been conducted. This study aimed to characterise the clinical and bacteriological profile of pyodermas, and to determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) infection in primary pyodermas in a dermatology outpatient department in Kashmir. Methods We conducted a hospital based cross-sectional study in the outpatient Department of Dermatology, Sexually Transmitted Diseases and Leprosy of Shri Maharaja Hari Singh Hospital, Srinagar, Jammu and Kashmir, India. Patients presenting with primary pyodermas were included in the study. A detailed history and complete physical and cutaneous examination was carried out along with microbiological testing to find aetiological microorganisms and their respectiveantimicrobial susceptibility patterns. Antimicrobial susceptibility testing, including that for methicillin resistance, was carried out by standard methods as outlined in the current Clinical and Laboratory Standards Institute guidelines. Results In total, 110 patients were included; the age of the study population ranged from 3 to 65 years (mean age 28 years); 62% were male. Poor personal hygiene was noted in 76 (69%). Furunculosis (56; 51%) was the most common clinical presentation. Staphylococcus aureus was isolated in 89 (81%) of cases, and MRSA formed 54/89 (61%) of Staphylococcus aureus isolates. All MRSA strains were sensitive to vancomycin. Conclusion The prevalence of MRSA was high in this sample of communityacquired primary pyodermas. It is therefore important to monitor the changing trends in bacterial infection and their antimicrobial susceptibility patterns and to formulate a definite antibiotic policy which may be helpful in decreasing the incidence of MRSA infection.

    This study was designed to evaluate the significance and interrelationship of clinical parameters and their association with histologic changes in advanced destructive periodontitis. 158 patients with PDI greater than 4 (Ramfjord) were selected, evaluating the size, contouring, bleeding, consistency, colour and gingival pain. Epithelial ulceration of soft periodontal pockets were also evaluated. The results showed a statistically significant association between purplish colour and gingival fibrosis and advanced stage of the disease. Gingival bleeding on probing was the most important clinical parameter in advanced phases of the disease, either alone or in association with other parameters such as the presence of epithelial ulcerations. The Periodontal Disease Index (Ramfjord) has proven effective in the evaluation of generalized patterns of disease. PMID:2637055

    Introduction Determination of post-traumatic interval remains one of the foremost important goals of any forensic investigation related to human crimes. The estimation of time since injury in cases of subdural haemorrhage has been studied only by a few investigators on the histological and radiological front. Aim The purpose of this study was to determine the post-traumatic interval of Subdural Haemorrhage (SDH) based on Hounsfield Unit measurements (HU) on Computed Tomography (CT) in surviving victims of head injury. Materials and Methods The study included a total of 100 cases of closed head injury with subdural haemorrhage. The Post-traumatic Time Interval (PTI) varied from 0.5 hours to a maximum of 249 hours, with a mean of 54.2 hours. Results Statistically significant results were obtained between the HU measurements of the SDH and the post-traumatic intervals and were found to be statistically significant. A rough attempt was made to determine the effect of haematoma volume on attenuation and was found out to be statistically insignificant. Conclusion The density of the subdural haematoma decreases with increase in the post-traumatic interval that concurs with the limited number of studies being conducted in the past. We concluded that further sorting of cases could be done according to its age with additional research and uniformity in the methodology. PMID:27190831

    Traumatic brain injuries (TBIs) represent a problem of public health all over the world if we consider its incidence, mortality and the big social costs. The increase of road and train traffic, the development of industry, the growth of alcohol consumption, the emergence and increase of terrorist attacks have led to more frequent and severe TBIs. There were registered 3260 deaths at the Institute of Forensic Medicine in Craiova, Romania, between 2010 and 2014; they were the result of severe traumas, 622 (19.07%) being caused by TBIs. The most affected by TBIs were men (the men÷women ratio was of 3÷1) and the elderly, mainly in the rural area. The main risk factor was alcohol intake; about 44% of the deceased people were under alcohol influence. The forensic examination highlighted the severity of cerebral meningeal lesions, the most frequent being cerebral and vascular lesions. The histopathological and immunohistochemical examinations emphasized various microscopic changes in accordance with the severity of the trauma and the time passed from impact until death.

    Micropapillary components are located in distinct, empty spaces resembling lymphatic vessels and consist of clusters of cancer cells that adhere tightly to one another. These structures do not have a fibrovascular core. Invasive micropapillary components (IMPCs) exhibit reverse polarity, which results in a characteristic ‘inside-out’ structure. The aim of the present study was to examine the histological significance of the micropapillary component in colorectal carcinoma compared with conventional colorectal adenocarcinoma. Among 115 patients, 5 (4.3%) were diagnosed with a micropapillary colorectal component based on hematoxylin and eosin staining and immunohistochemical analysis. To exclude identification of poorly-differentiated clusters of adenocarcinoma cells in the lymphatic vessels, immunohistochemical analysis with D2-40 was performed, and epithelial membrane antigen was used to confirm the specific ‘inside-out’ structure of IMPCs. IMPCs were observed to positively correlate with histopathological type (P=0.001) and tumor invasion in venous vessels (P=0.033). Furthermore, the presence and number of lymph node metastases was greater in IMPC cases compared with conventional carcinoma cases; however, these differences were not statistically significant (P=0.087 and P=0.094, respectively). In addition, IMPC cases were not significantly associated with the presence of inflammatory infiltrate in the invasive front of the tumor (P=0.098). Therefore, the present study indicates that the IMPC serves a histopathological and prognostic role in the diagnosis of colorectal cancer due to its aggressive and invasive behavior. IMPC is rare in cases of colorectal cancer and remains a great diagnostic challenge in pathomorphology with further detailed investigation required in the future. PMID:27446411

    Autoimmune hepatitis (AIH) is an unresolving progressive liver disease of unknown etiology characterized by hypergammaglobulinemia, autoantibodies detection and interface hepatitis. Due to the absence of specific diagnostic markers and the large heterogeneity of its clinical, laboratory and histological features, AIH diagnosis may be potentially difficult. Therefore, in this in-depth review we summarize the substantial progress on etiopathogenesis, clinical, serological and histological phenotypes of AIH. AIH has a global distribution affecting any age, both sexes and all ethnic groups. Clinical manifestations vary from asymptomatic to severe or rarely fulminant hepatitis. Hypergammaglobulinemia with selective elevation of IgG is found in most cases. Autoimmune attack is perpetuated, possibly via molecular mimicry, and favored by the impaired control of T-regulatory cells. Histology (interface hepatitis, emperipolesis and hepatic rosette formation) and autoantibodies detection although not pathognomonic, are still the hallmark for a timely diagnosis. AIH remains a major diagnostic challenge. AIH should be considered in every case in the absence of viral, metabolic, genetic and toxic etiology of chronic or acute hepatitis. Laboratory personnel, hepato-pathologists and clinicians need to become more familiar with disease expressions and the interpretation of liver histology and autoimmune serology to derive maximum benefit for the patient.

    Our concept of the functional-psychotic mental deterioration of schizophrenia approximately characterizes the same point of view as Kraepelin's terminus "Dementia praecox". The first result of our psychological examination on 225 schizophrenic persons with defect psychotic symptoms was the statement of the deficit in achievement between the former school education (average IQ of the school-type) and the results of examination of intelligence during our research. The functional-psychotic mental deterioration as well appears as a decrease of memory and psychomotoric speed deficiency, furthermore as mental deconcentration and increase of psychoorganic signs in the Rorschach-Test. The psychometric results of this research were statisticly significant.

    A macular-sparing superior altitudinal hemianopia with no visuo-psychic disturbance, except impaired visual learning, was associated with bilateral ischaemic necrosis of the lingual gyrus and only partial involvement of the fusiform gyrus on the left side. It is suggested that bilateral destruction of the lingual gyrus alone is not sufficient to affect complex visual processing. The fusiform gyrus probably has a critical role in colour integration, visuo-spatial processing, facial recognition and corresponding visual imagery. Involvement of the occipitotemporal projection system deep to the lingual gyri probably explained visual memory dysfunction, by a visuo-limbic disconnection. Impaired verbal memory may have been due to posterior involvement of the parahippocampal gyrus and underlying white matter, which may have disconnected the intact speech areas from the left medial temporal structures.

In six cases showing no X-ray symptoms, the diagnosis could only be confirmed by scintigraphy. A new classification of stages was necessary for therapeutic reasons: I = early stage, II = acute/subacute stage, III = healing stage, IV = defective recovery. Modifications due to therapy were demonstrated early by 100 scintigraphic check-up examinations, whereas the evidence of such modifications in X-ray pictures was delayed. The study describes the X-ray morphology as well as the scintigraphic manifestations of the Sudeck syndrome. The study shows that scintigraphy is a valuable examination method. It is useful in diagnosing early stages often not detected in X-ray examination, in the assessment of the evolution of a disease, and in the classification of stages. PMID:2467419

    In order to evaluate the potential value of telethermography in the early diagnosis of Sudeck's disease, the authors examined 10 patients presenting with this condition. Mean disease duration was 3.2 months and algodystrophic lesions in all patients were localized in one of the lower extremities. Ten healthy subjects, with mean age and sex distribution similar to those of the patients with Sudeck, were chosen as controls. Clinical examination, laboratory tests and telethermography were performed every two weeks for three months; X-rays of the affected limbs were also performed at the beginning and at the end of the study. All patients with algodystrophy were treated with salmon calcitonin (100 U.I./die/i.m. during the first 2 months and 100 U.I. on alternate days during the last month). Clinical-therapeutic thermographic monitoring showed that the localized hyperthermic pattern, initially shown in all patients (temperature levels at least three centigrades above normal values), later underwent a progressive time-related reduction leading to normalization. These results enable the authors to confirm the potential value of telethermography in the early diagnosis of Sudeck's disease and in its clinical monitoring, particularly in relation to therapy.

    Enterovirus 71 infection causes hand, foot and mouth disease in children, and can produce diverse neurologic complications. Epidemics occurring in Korea between 2009 and 2012 resulted in the death of some patients. The present study aimed to clarify the correlation between clinical features and MRI findings in patients presenting with acute neurologic manifestations related to enterovirus 71 infection. Based on their clinical features, the patients were classified into four clinical groups: (1) brainstem encephalitis (n=17), characterized by myoclonus, tremor, ataxia, and autonomic dysregulation such as pulmonary hemorrhage; (2) aseptic meningitis (n=2); (3) encephalitis (n=2), characterized by decreased consciousness, seizure, and fever without myoclonus, tremor, ataxia, and autonomic dysregulation; and (4) acute flaccid paralysis (n=1). Thirteen of the 17 patients with brainstem encephalitis showed characteristic lesions in the dorsal brainstem and bilateral cerebellar dentate nuclei on brain MRI, whereas three had no abnormality. One of the two patients with meningitis had a small lesion in the left dorsal pons. Two patients with encephalitis had no apparent MRI abnormality. One patient with acute flaccid paralysis of the right leg had contrast-enhancement of the bilateral ventral nerve roots at the lumbar spine level on MRI. Five of 13 patients with lesions in the bilateral dentate nuclei of the cerebellum exhibited no cerebellar symptoms, while two with no cerebellar lesions developed ataxia. Although most patients presenting with neurologic manifestations of enterovirus 71 infection had characteristic clinical features together with typical MRI findings, the clinical features were not necessarily consistent with MRI findings.

    2009-01-01

    Background Eggplant (Solanum melongena L.) is known to cause food allergy in some Asian countries but detailed studies on eggplant allergy are lacking. Objective The objective is to investigate sensitization to different parts of eggplant fruit, and detection of the allergens. Methods Six eggplant-allergic subjects were assessed for sensitization to eggplant (peel/pulp, and raw/cooked) by skin prick test, allergen-specific IgE, and immunoblots. Allergens were analyzed for glycoprotein nature by staining/lectinoblots, and in vitro stability in simulated gastric fluid. Results All the eggplant-sensitized subjects showed positive skin prick test with peel, pulp, raw, and cooked eggplant extracts; allergen-specific IgE to all these was positive. Raw eggplant contains 5 allergens in the range 36-71 kD. Most allergens are localized in the eggplant peel (9 allergens; 26-71 kD range) than the pulp (3 allergens; 52-71 kD); among these, the 26, 28, 36, and 71 kD allergens seem to be heat-stable. The 43, 45, 64, and 71 kD allergens are detected as glycoproteins; the 26, 64, and 71 kD allergens are stable displaying retention of IgE-binding ability in simulated gastric fluid digestion. Conclusions Eggplant is a multiallergenic vegetable in the context of presence of allergens in all edible parts of eggplant having preponderance in the peel. PMID:23283148

    Background: Bacteremia frequently occurs after treatment procedures such as extractions, scaling, root planing, periodontal surgery. There is currently significant interest in the possibility that bacteremia with oral bacteria may play role in pathogenesis of atherosclerosis. There are well-conducted studies that have determined the frequency of passage of periodontal microorganisms to the bloodstream after periodontal treatment. There is scarce information related to the incidence of periodontopathic microorganisms during bacteremia induced by this procedure. Aim: The aim of this study was to establish the frequency of passage of periodontopathic microorganisms in peripheric blood after scaling and root planing in patients with periodontitis. Materials and Methods: Forty subjects with chronic periodontitis were included in the study. Blood samples were drawn from each patient at following intervals pre-treatment i.e., before SRP (P1), immediately after SRP (P2), and 30 minutes after SRP (P3). Following SRP, blood samples were analyzed for following microorganisms: Porphyromonasgingivalis, Tannerella. forysthus, Eikenellanella. corrodens, Campylobacter species, Micromonas. micros, and Prevotella. intermedia. Statistical Analysis Used: Chi-square test. Results: Bacteremia was found in 70% (28/40) immediately after SRP and after 30 min, it was reduced to 25% (10/40) and 7.5% (3/40) presented bacteremia before SRP. Conclusions: It was concluded that bacteremia frequently occurs immediately after SRP with P. gingivalis showing the highest frequency in blood. PMID:24554880

    A 64-year-old diabetic man was treated for neovascular glaucoma with a pump-shunt implant (seton) after maximal medical therapy was unsuccessful. The seton, with supplemental agents, maintained the intraocular pressure (IOP) within a therapeutic range for 6 months, until the time of death from cardiac complications. Histopathologic evaluation of the eye showed the inlet of the seton in the periphery of the anterior chamber, not in contact with a coexisting anterior chamber intraocular lens (IOL). There was no fibrosis of the intracameral portion of the device. The tissue tract containing the silicon outlet tube extended from peripheral Descemet's membrane, through the sclera, to exit in the episcleral tissue over the posterior pars plana. Fibrous tissue originating from the episclera encased the external chambers of the seton. The internal contours of the fistulous tract, i.e., that portion adjacent to the seton, were smooth. There was no gross tissue hiatus at the exit port of the seton. The posterior wall of the fibrous capsule surrounding the seton in this region was diaphanous and immediately anterior to an area of cystic tissue comprising an equatorially placed bleb. The bleb was characterized by an irregular internal surface and a cystic cavity crossed by collagenous columns, suggesting it was the sub-Tenon's reservoir of aqueous. The success of the seton in this particular case may be due to a lack of fibrous reaction in the anterior chamber and the establishment of a stable filtering bleb in the equatorial region of the eye.

    The present experiment was executed to determine the pathological effects induced by concurrent feeding of butachlor (chloroacetanilide herbicide) in male Japanese quail. For this purpose mature male quail about 4-5weeks of age were procured from the local market and randomly divided into six equal groups (A-F). Butachlor was mixed in corn oil and administered orally for 30days using crop tube. Four birds from each group were killed at day 10, 20 and 30 of the experiment and blood was collected with and without anticoagulant. The birds in groups (A-D) did not reveal any clinical and behavioral alterations. Clinical signs like watery droppings, dullness, ruffled feather, depression, decrease frequency of crowing, mounting with pen mates and foam production were observed. Maximum intensity of these clinical signs and behavioral alterations were observed in group F throughout the experiment. Significant lower values of erythrocytes, hematocrit percent and hemoglobin were recorded. Significantly increased numbers of erythrocytes with micronuclei, lobed and notched nuclei were observed. Histopathologically, enlarged intertubular space, fewer numbers of round spermatids, necrotic spermatids and admixture of dead spermatids were observed in testes. The results revealed significant increase in serum lactate dehydrogenase (LDH), aspartate transaminase (AST), alanine transaminase (ALT) and urea concentrations. The results of present experimental study indicated that butachlor induces hematobiochemical and testicular changes in birds.

The steroid and the cream base uniformly used in all preparations were applied to the backs of 20 volunteers over 4 weeks. Dome-shaped red papules developed in the third week of occlusive treatment, and were counted in an area of 16 cm2 at the maximum of their development and graded according to a scale. The degree of papulation under diflucortolone valerate 0.1% was 2.15+/-0.75. No differences were observed between fluocortin butylester 0.75% (0.2+/-0.42), hydrocortisone acetate and the cream base (0.15+/-0.37). PMID:146498

    Helicobacter pylori is a spiral Gram-negative bacterium with a relatively small genome and is known to be the most common human bacterial infection worldwide, infecting about half of the world's population. The bacterium represents one of the most successful human pathogens, inducing severe clinical symptoms only in a small subset of individuals, thus signifying a highly balanced degree of co-evolution of H. pylori and humans. The prevalence of Helicobacter pylori infection varies greatly among countries and among population groups within the same country, but is falling in most developed countries. The clinical course of H. pylori infection is highly variable and is influenced by both microbial and host factors including genetic susceptibility while the pattern and distribution of inflammation correlate strongly with the risk of clinical sequelae, namely duodenal or gastric ulcers, mucosal atrophy, gastric carcinoma, or gastric lymphoma. Cytokine gene polymorphisms directly influence inter-individual variation in the magnitude of cytokine response, and this clearly contributes to an individual's ultimate clinical outcome. Polymorphisms in genes coding for innate immune factors have also been incriminated in the pathogenesis of H. pylori related disease, while promoter hypermethylation of tumor suppressor genes is considered an important factor in carcinogenesis and known to be present in H. pylori associated gastric tumors. Functional genomics may fill many of the gaps in our understanding of the pathogenesis of H. pylori infection and accelerate the development of novel therapies, including H. pylori specific antimicrobial agents.

    Introduction Chronic inflammatory periodontal diseases i.e. gingivitis and periodontitis are one of the most common afflictions faced by human beings. Dental plaque, which is a pool of pathogenic microorganisms, remains to be current mainstay in etiopathogenesis. Dental calculus, which is a mineralized product of this plaque remains ignored and is considered merely as an ash heap of minor significance. However, the intriguing array in disease etiopathogenesis bulldozed researchers to suspect the role of calculus in disease chrysalis but still the viability of bacteria inside calculus and thus its pathogenicity remains an intricacy; the answer to which lies in the Pandora’s Box. Aim The present study was undertaken to investigate the viability of bacteria within dental calculus along with their identification. Also, to classify dental calculus on the basis of mineralization and to observe the variation of viable microflora found in dental calculus with the extent of mineralization and disease severity. Materials and Methods A total of 60 samples were obtained, by harvesting two samples of supragingival calculus from each patient having chronic inflammatory periodontal disease. These samples were divided into two groups (Group A and Group B). Samples of Group A were kept non-irradiated and samples of Group B were exposed to UV radiation. The samples were categorized into less, moderately and highly mineralized according to the force required for crushing them. All the crushed calculus samples were then divided into three parts. These were used for dark-field microscopy, gram staining and bacterial cultures. Bacterial identification of the cultures obtained was also carried out by performing various biochemical assays. Results The present study revealed the presence of motile spirochaetes within the samples under dark-field microscope. Gram staining revealed presence of numerous gram positive cocci and gram negative bacilli. Bacterial cultures showed growth of variety of aerobic and capnophilic microorganisms. Conclusion The present study concludes the presence of viable aerobic and capnophilic bacteria inside dental calculus which may reside within the lacunae and channels in the calculus.

    This study was designed to evaluate the significance and interrelationship of clinical parameters and their association with histologic changes in advanced destructive periodontitis. 158 patients with PDI greater than 4 (Ramfjord) were selected, evaluating the size, contouring, bleeding, consistency, colour and gingival pain. Epithelial ulceration of soft periodontal pockets were also evaluated. The results showed a statistically significant association between purplish colour and gingival fibrosis and advanced stage of the disease. Gingival bleeding on probing was the most important clinical parameter in advanced phases of the disease, either alone or in association with other parameters such as the presence of epithelial ulcerations. The Periodontal Disease Index (Ramfjord) has proven effective in the evaluation of generalized patterns of disease.

    Sirenomelia is a social curiosity, a medical and diagnostic challenge prenatally compounded by varied diagnostic difficulties. Prenatal diagnosis of sirenomelia was and continues to be a challenge although von klippel et al., described a case at 10 weeks of gestational age. However, they needed a second imaging at 12th week for confirmation. First trimester or early second trimester anatomic survey on ultrasound and MRI is accurate for the diagnosis thereby avoiding unnecessary complex pregnancy. We report a case of second trimester diagnosed sirenomelia, with detailed analysis of image findings on ultrasound and fetal MRI. PMID:27504380

    A description is presented of a new and simple procedure for ventricular volume determination by means of pressure fixation of the heart and preparation of plastic molds of the ventricles which can be used to displace water in a graduated cylinder to determine the volume of the mold. Correlations between postmortem ventricular volume as measured by this method and antemortem stroke volume or clinical cardiac status indicate that a large left ventricular volume is often correlated with a low cardiac output and cardiogenic shock.

    Introduction Verrucous plaques mimicking chromoblastomycosis are frequently seen in dermatology outpatient departments (OPD). However, no scientific evaluation has been carried out till date from eastern India. So this present endeavour is aimed at a thorough study of those cases to readdress the challenges in diagnosis and management in chromoblastomycosis from this part of the country. Aim The study is to observe the incidence of proved chromoblastomycosis cases from clinically mimicking conditions and to note therapeutic prospects by use of different antifungal agents. Materials and Methods Twenty clinically suspected cases attending dermatology OPD were included in this study. Relevant histories were taken. Apart from routine hematological and biochemical investigations, scrapings from lesions were examined by direct microscopy with KOH wet mount, calcoflour white mount and fungal culture. Histopatholgical examination was also done. Any fungal growth was identified by growth characteristics and morphological features. Results Sclerotic bodies were detected in five samples. Of them three were found to be culture positive. Two growths were identified as Fonsecaea pedrosoi and one as Cladosporium carrionii. Rest 12 cases were diagnosed as either lupus vulgaris (3 cases; 15%), atypical mycobacterial infections (3 cases, 15%), Hypertrophic lichen planus (2, 10%), Hypertrophic DLE plaque (2; 10%), Wart (1, 5%) or fixed cutaneous sporothricosis (1, 5%), zygomycosis (1, 5%). Three cases (15%) were lost in follow up. Cases of chromoblastomycosis were managed with prolonged use of antifungal alone or in combination with saturated solution of potassium iodide and/or debridement. They were followed up for at least six months post treatment. Conclusion A database comprising diagnostic clues and effective therapeutic intervention have been proposed for these rare subcutaneous mycoses. PMID:26816977

    Bacterial keratitis is an acute or chronic, transient or recurrent infection of the cornea with varying predilection for anatomical and topographical parts of the cornea like marginal or central. It is a potentially sight-threatening corneal infection in humans that is generally found in eyes with predisposing elements, the most common of which is contact lens wear. The epidemiological data reveals the universal occurrence of this disease. With advances in the understanding of its pathogenesis, laboratory investigations like immunohistochemistry, fluorescent microscopy, enzyme immunoassays and molecular biology, and the availability of fourth generation antibiotics, the overall visual outcome in bacterial keratitis has improved with time. Particular attention should be given to this condition as it can progress very rapidly with complete corneal destruction occurring within 24–48 hours. Early diagnosis, which is primarily clinical and substantiated largely by microbiological data, and prompt treatment are needed to minimise the possibility of permanent visual loss and reduce structural damage to the cornea.

    Amebic Meningoencephalitis (AM) and Primary Amebic Meningoencephalitis (PAM) are infectious diseases essentially confined to the Central Nervous System (CNS) and caused by free-living amebas of the genus Acanthamoeba (A.) and Naegleria (N.) respectively. AM due to A. sp. (Acanthamoeba castellanii and Acanthamoeba culbertsoni) have been reported in chronically ill debilitated individuals, some of them under immunosuppressive therapy, or in immunologically impaired patients without a history of recent swimming in contrast to cases due to N. sp. which usually occurs in healthy, young individuals with a recent history of swimming in man-made lakes or heated swimming pools. AM due to A.sp. is characterized by a subacute or chronic granulomatous meningoencephalitis involving mainly the midbrain, basal areas of the temporal and occipital lobes and posterior fossa structures. CNS lesions in AM are perhaps secondary and the portal of entry in humans is probably from the lower respiratory tract, genitourinary system or skin reaching the CNS by hematogenous spread. The predominant host reaction is usually composed of lymphocytes, plasma cells, monocytes and multinucleated foreign body giant cells. Necrosis is moderate and hemorrhage scant or absent. Cysts as well as trophozoites may be seen within the CNS lesions. PAM is due to Naegleria fowleri and is characterized by an hemorrhagic necrotizing meningoencephalities with an acute inflammatory response. Only trophozoites are found in lesions. The portal of entry is through the olfactory neuroepithelium. CNS tissues fixed in formalin may be used for further identification and taxonomical classification of the causative protoza using immunofluorescent antibody techniques (IFAT) and electron microscopic methods.

    Effective analgesia under conditions of emergency and disaster is still a problem which can be considered as unsolved. The i.m. administration of ketamine in subanaesthetic doses could be one step forward, particularly in regard to a possible application by paramedical personnel. In order to evaluate this hypothesis, we compared 2 groups of 6 patients each, who received either 0.5 mg/kg or 1 mg/kg ketamine respectively i.m. for p.o. pain relief after tonsillectomies. The analgesic efficacy, the levels of consciousness, the blood pressure values and the ketamine plasma levels demonstrated, that effective analgesia can be obtained within 10 min following either dose. The dosage of 1 mg/kg however was followed by a transient impairment of the levels of consciousness. The pharmacokinetic data may lead to the conclusion that analgesia starts above plasma levels of 100 ng/ml. Important side effects were not be observed in these few cases. A further study, which has almost been completed, will demonstrate whether the same results apply to emergency out-patients suffering from fractures, burns etc. PMID:6614421

    Objective: Tuberculosis (TB) is a major public health problem in Bangladesh since long. The present incidence and prevalence rates of all forms of TB are 227 and 404/100,000 population respectively. The aim of this study was to find out the clinical characteristics of involved cervical lymph nodes, demographic characteristics of the patients and response to treatment of Cervical Tuberculous Lymphadenitis (CTL) cases. Methods: A prospective study was performed in Shaheed Shamsuddin Ahmed Hospital, Sylhet, Bangladesh from June 2012 to June 2014. Total 65 patients having CTL attending outpatient department of the hospital were enrolled. Results: Age of the patients ranged from 5 to 60 years with a mean of 25.6 years. Two third (67.7%) of the patients were female. Male: Female ratio was 1:2.1. More than half of the patients came from rural areas (53.8%) and from low socio-economic conditions (58.5%). Most of the patients presented with unilateral (87.7%), multiple (82.3%), matted (68.6%) lymph nodes, <3cm diameter (54%), commonly in right side (57.9%). Abscess was found in 21.5% cases. Discharging sinus was found in 9.2% cases. Most commonly involved lymph node group was level V (59.4%) followed by level II (42.2%). Systemic features were found in 63.07% patients. Associated lung lesion was found in 3.1% cases. FNAC was found positive for tuberculosis in 83.9% cases. Most of the patients (78.46%) were cured with six months anti-tubercular chemotherapy. Conclusions: Early diagnosis and treatment is critical in reducing the overall prevalence. It is essential to have awareness regarding common presentations of cervical tuberculous lymphadenitis among the general population as well as healthcare professionals working in the resource poor primary and secondary level hospitals.

    Background Leptospirosis, a zoonosis associated with potentially fatal consequences, has long been a grossly underreported disease in India. There is no accurate estimate of the problem of leptospirosis in non-endemic areas such as north India. Methods/Principal Findings In order to understand the clinical spectrum and risk factors associated with leptospirosis, we carried out a retrospective study in patients with acute febrile illness in north India over the last 5 years (January 2004 to December 2008). There was increased incidence of leptospirosis (11.7% in 2004 to 20.5% in 2008) as diagnosed by IgM ELISA and microscopic agglutination titer in paired acute and convalescent sera. The disease showed a peak during the rainy season (August and September). We followed up 86 cases of leptospirosis regarding their epidemiological pattern, clinical features, laboratory parameters, complications, therapy, and outcome. Mean age of patients was 32.6 years (2.5 years to 78 years) and males (57%) outnumbered females (43%). Infestation of dwellings with rats (53.7%), working in farm lands (44.2%), and contact with animals (62.1%) were commonly observed epidemiological risk factors. Outdoor workers including farmers (32.6%), labourers (11.6%), para-military personnel (2.3%), and sweepers (1.2%) were commonly affected. Modified Faine's criteria could diagnose 76 cases (88.3%). Renal failure (60.5%), respiratory failure (20.9%), the neuroleptospirosis (11.6%), and disseminated intravascular coagulation (DIC) (11.6%) were the commonest complications. Five patients died, giving a case fatality rate of 5.9%. Conclusions/Significance There has been a rapid rise in the incidence of leptospirosis in north India. Severe complications such as renal failure, respiratory failure, neuroleptospirosis, and DIC are being seen with increasing frequency. Increased awareness among physicians, and early diagnosis and treatment, may reduce mortality due to leptospirosis. PMID:20084097

    Herpes Simplex Virus Type 1 (HSV-1) is a nuclear replicating enveloped virus, usually acquired through direct contact with infected lesions or body fluids (typically saliva). The prevalence of HSV-1 infection increases progressively from childhood, the seroprevalence being inversely related to socioeconomic background. Primary HSV-1 infections in children are either asymptomatic or following an incubation period of about 1 week gives rise to mucocutaneous vesicular eruptions. Herpetic gingivostomatitis typically affects the tongue, lips, gingival, buccal mucosa and the hard and soft palate. Most primary oro-facial HSV infection is caused by HSV-1, infection by HSV-2 is increasingly common. Recurrent infections, which occur at variable intervals, typically give rise to vesiculo-ulcerative lesions at mucocutaneous junctions particularly the lips (herpes labialis). Recurrent HSV-1 infection within the mouth is uncommon in otherwise healthy patients, although in immunocompromised patients, recurrent infection can be more extensive and/or aggressive. The diagnosis of common herpetic infection can usually be based upon the clinical history and presenting features. Confirmatory laboratory diagnosis is, however, required when patients are, or may be, immunocompromised.

    Sepsis is a common cause of death, but outcomes in individual patients are difficult to predict. Elucidating the molecular processes that differ between sepsis patients who survive and those who die may permit more appropriate treatments to be deployed. We examined the clinical features, and the plasma metabolome and proteome of patients with and without community-acquired sepsis, upon their arrival at hospital emergency departments and 24 hours later. The metabolomes and proteomes of patients at hospital admittance who would die differed markedly from those who would survive. The different profiles of proteins and metabolites clustered into fatty acid transport and β-oxidation, gluconeogenesis and the citric acid cycle. They differed consistently among several sets of patients, and diverged more as death approached. In contrast, the metabolomes and proteomes of surviving patients with mild sepsis did not differ from survivors with severe sepsis or septic shock. An algorithm derived from clinical features together with measurements of seven metabolites predicted patient survival. This algorithm may help to guide the treatment of individual patients with sepsis. PMID:23884467

    2014-01-01

    Background Intestinal schistosomiasis, caused by digenetic trematodes of the genus Schistosoma, is the most prevalent water related disease that causes considerable morbidity and mortality. Although prevalence of Schistosoma mansoni infection has been reported for the present study area, earlier studies have not estimated intensity of infections in relation to periportal fibrosis, which would have been crucial for epidemiological and clinical evaluations. Hence, a community based cross sectional study was conducted from December 2011 to March 2012 to assess prevalence of infection and schistosomal periportal fibrosis in Waja-Timuga, northern Ethiopia. Methods In a cross sectional study involving 371 randomly selected individuals, fresh stool samples were collected and processed by the Kato-Katz method and examined microscopically. Ultrasonography was used to determine status of schistosomal periportal fibrosis and to detect hepatomegaly and/or splenomegaly. Serum was collected for assay of hepatic activity. Statistical analysis was performed using STATA 11 statistical soft ware. P-value <0.05 was reported as statistically significant. Results The prevalence of S.mansoni infection was 73.9%, while the prevalence of schistosomal periportal fibrosis was 12.3% and mean intensity of infection was 234 eggs per gram of stool. Peak prevalence and intensity of S.mansoni infection was documented in the age range of 10–20 years. Among the study individuals, hepatomegaly was recorded in 3.7% and splenomegaly was recorded in 7.4% of the study individuals. Similarly, among the study individuals who had definite periportal fibrosis, 5.9% had elevated liver enzyme levels. Conclusion The high prevalence of Schistosoma mansoni infection and schistosomal periportal fibrosis observed in the study area calls for a periodic deworming program to reduce disease, morbidity and transmission. Preventive chemotherapy complemented with other control measures is highly required for sustainable control of schistosomiasis in the study area. PMID:24690404

    Due to the great amount of asthmatic patients presenting complications which could endanger their lives, a revision of the possible threatening factors is carried out. The factors concurring with the base pathologic mechanism are analyzed and it is demonstrated, that some of these factors intervene independently from bronchial asthma. The study is carried out on the basis of age, sex, hospital stay duration, clinical picture, blood gases analysis, complications and pathology findings: 1) Most of the deceased patients presented various pathologies besides bronchial asthma which contributed to the decease. 2) The physician should be alert in order to establish good therapeutic procedure in these patients which could carry other important complications; these complications are responsible for the fatal outcome in a great number of patients. A complication should always be searched for, e.g. pneumothorax. 3) The vast majority of patients who passed away in status were relatively young. 4) A female predominance was found. 5) All patients before entering our Center, presented asthma crisis at least three days prior to admission. 6) The predominant hospital stay duration was 24 hours. 7) The most common pathologic findings were: pulmonary fibroemphysema, acute bronchopneumonia, bronchial mucoid plugging, atelectasia and cerebral edema. 8) Cerebral edema and compression of the amygdale were common brain pathologic findings. 9) Bronchopneumonia was a common necropsy finding. 10) Based on these findings, ICU treatment is extremely important. 11) The critical status of the patient in the moment of admission, is due to the delay in bringing him to the hospital for proper medical surveyance. This justifies the interest of the Public Health Department in ample distribution of proper information to the asthmatic patients. PMID:1155315

    Introduction: There is a constant need to define the epidemiological and mycological characteristics of onychomycosis (OM) for optimal management strategies. Objectives: To define the epidemiological and mycological characteristics of patients with dermatophyte toenail OM in a tertiary care hospital. Materials and Methods: Hundred consecutive patients of KOH and culture-positive dermatophyte toenail OM were subjected to detailed history, clinical examination and investigations. Results: Maximum number of patients (40%) belonged to 31-45 years age group and there was a male preponderance (M:F = 6.7:1). The mean duration of disease was 54 months. Thirty-three patients had fingernail involvement in addition to the toenail OM and 37% had co-existent cutaneous dermatophyte infection. Discoloration was the most common symptom (98%). Ninety-four (94%) patients had distal lateral subungual onychomycosis (DSLO) while two had superficial onychomycosis (SO) and only one had proximal superficial onychomycosis (PSO). Trichophyton interdigitale was the most common etiological agent (61%) followed by Trichophyton rubrum and Trichophyton verrucosum. Conclusions: Toenail OM is more common in males. DSLO was the most common clinical variant and T. interdigitale the most common etiological fungus responsible for toenail OM in our region. The importance of early diagnosis and treatment is highlighted as long-standing toenail OM predisposes to fingernail onychomycosis and recurrent tinea pedis. PMID:25814703

  9. RET/PTC Translocations and Clinico-Pathological Features in Human Papillary Thyroid Carcinoma

    2012-01-01

    Thyroid carcinoma is the most frequent endocrine cancer accounting for 5–10% of thyroid nodules. Papillary histotype (PTC) is the most prevalent form accounting for 80% of all thyroid carcinoma. Although much is known about its epidemiology, pathogenesis, clinical, and biological behavior, the only documented risk factor for PTC is the ionizing radiation exposure. Rearrangements of the Rearranged during Transfection (RET) proto-oncogene are found in PTC and have been shown to play a pathogenic role. The first RET rearrangement, named RET/PTC, was discovered in 1987. This rearrangement constitutively activates the transcription of the RET tyrosine-kinase domain in follicular cell, thus triggering the signaling along the MAPK pathway and an uncontrolled proliferation. Up to now, 13 different types of RET/PTC rearrangements have been reported but the two most common are RET/PTC1 and RET/PTC3. Ionizing radiations are responsible for the generation of RET/PTC rearrangements, as supported by in vitro studies and by the evidence that RET/PTC, and particularly RET/PTC3, are highly prevalent in radiation induced PTC. However, many thyroid tumors without any history of radiation exposure harbor similar RET rearrangements. The overall prevalence of RET/PTC rearrangements varies from 20 to 70% of PTCs and they are more frequent in childhood than in adulthood thyroid cancer. Controversial data have been reported on the relationship between RET/PTC rearrangements and the PTC prognosis. RET/PTC3 is usually associated with a more aggressive phenotype and in particular with a greater tumor size, the solid variant, and a more advanced stage at diagnosis which are all poor prognostic factors. In contrast, RET/PTC1 rearrangement does not correlate with any clinical–pathological characteristics of PTC. Moreover, the RET protein and mRNA expression level did not show any correlation with the outcome of patients with PTC and no correlation between RET/PTC rearrangements and the expression level of the thyroid differentiation genes was observed. Recently, a diagnostic role of RET/PTC rearrangements has been proposed. It can be searched for in the mRNA extracted from cytological sample especially in case with indeterminate cytology. However, both the fact that it can be present in a not negligible percentage of benign cases and the technical challenge in extracting mRNA from cytological material makes this procedure not applicable at routine level, at least for the moment.

    Introduction Chronic inflammatory periodontal diseases i.e. gingivitis and periodontitis are one of the most common afflictions faced by human beings. Dental plaque, which is a pool of pathogenic microorganisms, remains to be current mainstay in etiopathogenesis. Dental calculus, which is a mineralized product of this plaque remains ignored and is considered merely as an ash heap of minor significance. However, the intriguing array in disease etiopathogenesis bulldozed researchers to suspect the role of calculus in disease chrysalis but still the viability of bacteria inside calculus and thus its pathogenicity remains an intricacy; the answer to which lies in the Pandora’s Box. Aim The present study was undertaken to investigate the viability of bacteria within dental calculus along with their identification. Also, to classify dental calculus on the basis of mineralization and to observe the variation of viable microflora found in dental calculus with the extent of mineralization and disease severity. Materials and Methods A total of 60 samples were obtained, by harvesting two samples of supragingival calculus from each patient having chronic inflammatory periodontal disease. These samples were divided into two groups (Group A and Group B). Samples of Group A were kept non-irradiated and samples of Group B were exposed to UV radiation. The samples were categorized into less, moderately and highly mineralized according to the force required for crushing them. All the crushed calculus samples were then divided into three parts. These were used for dark-field microscopy, gram staining and bacterial cultures. Bacterial identification of the cultures obtained was also carried out by performing various biochemical assays. Results The present study revealed the presence of motile spirochaetes within the samples under dark-field microscope. Gram staining revealed presence of numerous gram positive cocci and gram negative bacilli. Bacterial cultures showed growth of variety of aerobic and capnophilic microorganisms. Conclusion The present study concludes the presence of viable aerobic and capnophilic bacteria inside dental calculus which may reside within the lacunae and channels in the calculus. PMID:27630958

    Tibezonium iodide is a new drug having antibacterial activity for the therapy and the prevention of mouth infections. Before testing its therapeutic efficacy, its effect on the bacterial flora of the human saliva was verified as follows. Salivary samples, collected before and after the administration (double-blind, cross-over) to volunteers, were counted for bacteria. The drug reduced the bacterial count in the saliva with statistical significance in both the pharmaceutical forms. Subsequently the drug was tested in different dental or oral conditions. To 90 patients suffering from marginal paradentitis or other diseases with this type of complications tablets were administered. The results obtained in this group were satisfactory or almost satisfactory in 73.5% of the cases examined. The patients treated with bubble-gums were 70. All of them were suffering from the same kind of disease of the first group; a few of them had alveolitis following tooth extraction. The results in these subjects were satisfactory or almost satisfactory in 77% of the cases examined. Tibezonium proved to be particularly effective in marginal paradentitis and in piorrhoic paradontosis. Bubble-gums should not be used in subjects with dental mobile prosthesis. PMID:794686

    203 patients with juvenile angiofibroma of the base of the skull were assessed clinicoanatomically. In addition to a routine otorhinolaryngological examination 60 patients underwent computed tomography, radioangiography and thermography. Biopsy specimens obtained at operations were studied morphologically for 133 patients including application of histotopography in 15 cases and electron microscopy in 19 cases. Two clinicoanatomic forms of juvenile angiofibroma (JAF) have been revealed as well as 4 vascular types and variegation due to different combinations of vascular, cellular and fibrillar components. According to biologic nature of JAF it should be referred to fibromatoses.

    Both brachialis and biceps brachii are primary flexors of the arm and elbow from the biomechanical perspective. Numerous reports exist in anatomical literature regarding accessory heads of biceps brachii, although such accessory bellies in relation to brachialis muscle are less frequently elucidated. We report a unilateral case of a rare accessory muscle interposed between the biceps brachii and brachialis, having the musculocutaneous nerve (MCN) entrapped between the two. Furthermore, the muscle divided into two slips, upper slip was attached to biceps brachii and the other gained insertion to the brachial fascia. Innervation to this accessory muscle was derived from MCN. The embryological basis for such supernumerary muscle is discussed. Additionally, the case is considered under surgical and clinical perspective, highlighting the importance of familiarity with such variations. Anatomical variations of the brachial musculature may cause diagnostic perplexities while interpreting MRI or CT scans.

    Aims: To study the histological features on muscle biopsy and correlate them with clinical features, other laboratory data in adult patients to make a diagnosis of dermatomyositis (DM), applying the European Neuromuscular center (ENMC) criteria. Materials and Methods: Adult patients who fulfilled clinical, laboratory, and muscle biopsy findings according to ENMC criteria for DM during the period 2010–2013 were included in the study. Cryostat sections of muscle biopsy were reviewed with emphasis on Perifascicular atrophy (PFA), perivascular/endomysial inflammation. Muscular dystrophies and metabolic myopathies were excluded by appropriate immunohistochemistry and special stains. Results: The diagnosis of adult DM was made in 45 patients out of 170 clinically suspected idiopathic inflammatory myopathies. These included 33 definite, 4 probable, 7 possible sine dermatitis, and 1 amyopathic DM. All patients with definite DM had typical rash and proximal muscle weakness and muscle biopsy showed PFA with or without inflammation. Thirteen patients had quadriparesis, neck muscle weakness, dysphagia/dysphonia at presentation. Patients with probable DM had rash and showed perivascular/endomysial inflammation with no PFA. Possible DM sine dermatitis showed PFA with perivascular/endomysial infiltrates. One patient of amyopathic DM had typical heliotrope rash and characteristic skin biopsy. Conclusions: Histological features are important for the diagnosis of DM. Relying on PFA for diagnosis of definite DM underestimates the true frequency of DM. PMID:26019418

    Dengue is the fastest emerging arboviral infection and became a major public health concern in tropical and subtropical countries. Dengue infections can result in a wide spectrum of disease severities ranging between dengue fever (DF) to the life-threatening dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). This study was performed to find out the varied presentations and laboratory findings to put forward an overview about dengue syndrome in Bangladesh, in order to create better awareness and diagnostic skills among the health care providers. This hospital based observational study was conducted in the department of Medicine, Square Hospitals Ltd. during January, 2008 to December, 2010. A total of 262 adult subjects of both sexes having dengue syndrome were included in this study. Dengue syndrome was common in younger age group and the majority (72%) was below 45 years of age. All the patients had fever and the majority had malaise (96%), severe headache (72%) and musculoskeletal pain (65%). Skin rash (47%) was the commonest hemorrhagic manifestation while tourniquet test (49%) and low pulse pressure (37%) were the commonest clinical signs. All had thrombocytopenia (100%) and the majority had leukopenia (84%) and elevated liver transaminase (ALT-74%, AST-88%). Most of the subjects developed anti dengue antibody (IgM-92%, IgG -72%). All subjects survived.

    This cross-sectional study was carried out to explore the epidemiological and clinical features of dengue fever in Faisalabad, Pakistan during 2011 and 2012. During the study period, anti-dengue IgM positive cases were reported in the post-monsoon period during the months of August-December. Certain hotspots for the dengue infection were identified in the city that coincide with the clusters of densely populated urban regions of the city. Out of total 299 IgM positive patients (male 218 and female 81); there were 239 dengue fever (DF) and 60 dengue hemorrhagic fever (DHF) patients. There was decrease in the median age of dengue patients from 31 years in 2011 to 21.5 years in 2012 (p<0.001). Abdominal pain was seen in 35% DHF patients followed by nausea in 28.3%, epistaxis in 25% and rash in 20% patients (p<0.05). Patients reported to be suffering from high-grade fever for an average of 8.83 days in DHF as compared to 5.82 days in DF before being hospitalized. Co-morbidities were found to be risk factor for the development of DHF in dengue patients. Clinical and laboratory features of dengue cases studied could be used for the early identification of patients at risk of severe dengue fever.

    Neurological manifestations due to Dengue virus (DENV) infection are atypical and uncommon. Genomic information of clinically characterised, neurotrophic DENV in humans is extremely limited albeit their importance in deciphering the pathogenicity is substantial. Here, we report a rare case of fatal DENV-4 infection complicated with encephalitis and multi-organ failure. The clinical presentation was unusual due to its rapid onset of encephalitis despite a very low virus titre. Full genomes of serum and CSF-derived viruses shared 99.99% similarity, indicating the virus dissemination across blood-brain barrier. Even though virus genomes did not reveal any of the neurotrophic substitutions of DENV documented so far, case isolates possessed a combination of 8 novel amino acid alterations, predominantly distributed in non-structural genes of DENV-4.

    The present study included 201 adult patients presenting with exacerbation of chronic maxillary sinusitis. The presence of Chlamydia trachomatis and Chl. pneumoniae was verified by the direct immunofluorescencetechnique and polymerase chain reaction. The study material consisted of swipes und swabs from the mucous membrane of the middle nasal passage. The information from the patients was collected with the use of a questionnaire specially elaborated for the purpose of this study. The correlation relationships were established by means of gamma-statistics. The method is based on the calculation of the integral index characterizing the risk of development of chlamydial infection using the scoring scale for the evaluation of the clinical and anamnestic characteristics of the patients. The assessment of the risk of chlamydial colonization by the anamnestic method makes it possible to enhance the effectiveness of clinical diagnostics of chlamydial infection and thereby provides a basis for the prescription of the adequate anti-chlamydial treatment facilitating reduction of the frequency of complications and preventing dissemination of the causative factor of the disease. Moreover, this approach creates the conditions for the targeted selection of the patients to be referred to the laboratory verification of Chlamydia. Highoperating performance and effectiveness characteristics of the clinic-anamnestic diagnostics make it a method of choice for the wide application in the clinical practice. PMID:27500582

    Background: Saliva represents an increasingly useful tool of diagnosis. Several factors such as salivary flow rates (SFRs) (unstimulated and stimulated) (U and S), pH, buffering capacity and consistency can be altered due to several disease processes or medications prescribed for various diseases. Alterations of SFRs, pH, buffering capacity and various ion concentrations can influence the pathogenesis of some of the oral diseases. Aim: Evaluation of the effect of diuretics on oral health status with regard to SFRs (U and S), pH, buffering capacity, total protein content, various ion concentrations and oral mucosal lesions. Subjects and Methods: A total of 100 patients were categorized into test group and control group based on usage of diuretics. Unstimulated and stimulated saliva were collected and evaluated for flow rates. Salivary pH was measured using pH meter. Buffering capacity was measured using Aranha's technique. Salivary Na+, K+ and Cl− concentrations were measured using electrolyte analyzer CORNLEY ACCULYTE-3P in ion-selective electrode method. Salivary total protein content was measured by spectrophotometric method. Dental Caries and periodontal status were measured by using decayed, missing, filled teeth index and Russell's periodontal index respectively. Oral mucosal examination was carried out to identify the mucosal lesions. Results: The obtained results were subjected to statistical analysis using Statistical package for social sciences software (SPSS), version 16, IBM Company by Chi-square test and unpaired t-test. Highly significant P for alterations of SFR/U (P < 0.001), SFR/S (P < 0.001), pH (P < 0.001), Na+ concentration (P < 0.001), buffering capacity (P < 0.001) and moderate significance for Cl− concentration (P < 0.01) were found. Alterations of total protein (P = 0.14) and K+ (P = 0.65) concentrations were not statistically significant. High prevalence was found for caries (P < 0.01), periodontal status (P < 0.001) and mucosal lesions (P < 0.01). Conclusion: Our study shows that diuretic medication significantly reduces SFRs (xerostomia) and alters salivary composition which may have an impact on the incidence of dental caries, periodontal diseases and mucosal lesion formation.

    Extensor tendon injury is a frequent finding in clinical practice. During a routine dissection class of undergraduate medical students examining the extensor aspect of the right hand, they found an interesting pattern of extensor tendons. The extensor digitorum (ED) exhibited three tendons for the middle and ring fingers. The intermediate tendon of the ED was found to pass to the junctura connecting the tendons of the ring and middle fingers. Additionally the Extensor carpi ulnaris displayed two tendinus slips. The lateral slip was inserted on the base of fifth metacarpal as usual, whereas the medial slip divided into two strands- proximal and distal. Apart from the above findings in the current case specimen, there was an accessory muscle belly for the index finger and the extensor digiti minimi bifurcated into two tendinus slips which gained attachment to the dorsal digital expansion of the little finger. These accessory muscle bellies and tendons could possibly be utilized for tendon reconstructions such as repairs, tenoplasties or tendon transfers.

    Clinical and morphological comparisons were conducted in 31 patients with thrombosis and insufficiency of mitral valve prostheses. The morphology of these complications was studied on the basis of autopsy data in 19 cases, and in 12 reoperations. Prosthetic thrombosis was observed in 18 patients. The leading causes of the functional disorders in the prosthesis were septic complications, persisting hypotension in the early postoperative period, errors of anticoagulation therapy. The clinical manifestations of thrombosis of a prosthesis depend on the extent and localization of the thrombus. An important role in the diagnosis of such complications belongs to a dynamic observation, especially to repeated phonocardiographic examinations. A phonocardiographic semiotics of the complications is presented. The results of reoperations for thrombosis of a mitral valve prosthesis and its insufficiency are also presented. The rationale of secondary interventions is demonstrated.

This allows to study not only incidence of this tumor depending on the site, sex and age, but to give new data on its biology. The malignancy of all the three types of this tumor (of low, moderate and high grade) was confirmed by means of histologic, histochemical, electron-microscopic (EM) and EM-histochemical methods. The previous assumption on benign character of the low-grade variant of the tumor was not confirmed.

    We carried out a retrospective study on non-neoplastic enlargement of the salivary glands at the Oral Histopathology Diagnostic Center of the Autonomous Metropolitan University at Xochimilco (UAM-Xochimilco) in Mexico during a period of 24 years (1979-2003). From 5,625 biopsies received and analyzed, a total of 461 (8.2%) were non-neoplastic enlargement of the salivary glands; for each case, we registered demographic data as well as clinic characteristics. These lesions were characterized as a heterogeneous group of pathologic entities among which we included local, obstructive, infectious, and immunopathologic lesions. The most frequent lesion was the extravasation cyst in 341 (74%) cases, followed by chronic sialoadenitis and Sjögren's syndrome with 54 (11.7%) and 41 (8.8%) cases, respectively, and at a lesser percentage mucous retention cyst, sialosis, benign lymphoepithelial lesions and those related with sialolytes. Females were affected more frequently; mean age was second to third life decades. These lesions were most frequently localized on inferior labial mucosa.

    Gastric xanthoma has been associated with helicobacter pylori and chronic gastritis by many authors, some authors think the inflammation gives rise to them. This is a descriptive study in all cases of gastric xanthoma whose diagnosis was made during 1999 to June 2005, a simple statistical analysis was used. We found 26 cases, frequency peaked in those from 50-69 years of age (46.1%), gastric xanthoma was most frequently found in the antrum (69.5%), Helicobacter pylori was found in 11 cases (42.3%) and intestinal metaplasia was found in 10 (38.4%). Our results are similar to those obtained by others authors., we think chronic gastritis and gastric xanthoma share the same origin , but this affirmation must be confirmed by studies with greater statistical value.

    Two hundred and fifty cases of histologically proven Hodgkin's disease have been reviewed. These cases were classified according to the Rye Conference histological classification (Lukes et al., 1966a) and according to the Cross classification (Cross, 1969). Overall, both classifications were reasonably effective in predicting prognosis but that of Cross with its seven sub-groups proved more difficult to use than the simpler Rye classification. In all cases the follow-up period exceeded 5 years. A study was made of the influence of clinical symptoms on survival with particular reference to night sweats, fever, pruritus, anorexia, lassitude, weight loss, haematological abnormalities and splenic enlargement. The presence of these abnormalities adversely affected prognosis. The spread of the disease from one group of nodes to the next was also documented. Considering all cases the 5-year survival was 54%. The 5-year survivals according to histological type were: lymphocytic predominance 69%, nodular sclerosis 57%, mixed cellularity 41%, lymphocytic depletion 40%. The 10-year survival was 23% which, when corrected by the actuarial method (Berkson and Gage, 1950), rose to 36%. The importance of symptomatology as well as histological grading in the prognosis of Hodgkin's disease is confirmed.

    This cases series describes the profile of adult patients with acute promyelocytic leukaemia (APt) at a referral hospital in Qatar. Of 34 acute myeloid leukaemia (AML) cases diagnosed, 11(32%) were classified as APt. Disseminated intravascular coagulation was common at presentation (91%). Severe thrombocytopenia was seen in 73%, leukocytosis in 55% and severe anaemia in 45%. Only 2 patients were of the classic hypergranular type. In the remaining 9 patients, 3 morphological subtypes were recognized: microgranular variant (6 patients), hyperbasophilic (2 patients) and regular nuclear outline M3r (1 patient). Translocation t(15;17) was detected in 63% of cases. APL constitutes a high proportion of AML cases in Qatar, with considerable morphological heterogeneity and a oredominance of APL variants with unfavourable oresenting features. PMID:21218723

    Background: The dimensions of dentogingival junction have been evaluated from autopsy jaw specimens. Previous studies demonstrated variability in histologic biologic width (BW) in periodontal health and mild periodontitis. Few studies have been done on the measurement of clinical BW in periodontitis. BW variation provides implications for selection of surgical or nonsurgical approaches. The purpose of this study was to determine clinical BW in periodontal health and chronic generalized periodontitis and to compare it with histologic dimensions of BW. Materials and Methods: A total of 20 subjects with chronic generalized periodontitis and 20 subjects with healthy periodontium were included in the present study. Plaque index and community periodontal index of treatment needs were scored; moreover, probing depth (PD) and clinical attachment level were measured. Full mouth intraoral periapical radiographs were taken, and digitalized images were obtained to measure the crestal bone level using computerized software. Results: Clinical BW was significantly greater in both healthy and periodontitis groups than previously reported histologic BW of 2.04 mm (P < 0.001). The mean clinical BW was 3.98 mm. Conclusion: Mean clinical BW in both groups was significantly greater than histologic BW and sites with shallow PDs demonstrated greatest BW, suggesting that these sites may be at increased risk for losing significant attachment during surgical procedures.

    Introduction Clinically, subcoracoid impingement is characterized by pain at the anterior aspect of the shoulder that is induced by adduction, internal rotation and forward flexion. This position leads to narrowing of the Coraco-Humeral Interval (CHI)-that is, the space between the coracoid process and the lesser tuberosity of the humerus. Structures in the rotator interval are at greatest risk for impingement which includes the Subscorapularis tendon, tendon of the long head of the biceps, and the middle gleno-humeral ligament. This may result in Rotator interval pathologies such as subscapularis tear and long head of biceps tendon subluxation or fraying. Aim To study the prevalence of radiological evidence of reduced Coraco-Humeral Interval (CHI) in patients with clinically evident Subcoracoid impingement and to examine the presence of Subscapularis tears in these patients. Materials and Methods Twenty four patients (6 males, 18 females, average age 52.83 years) were included in this prospective study who were diagnosed to have rotator cuff tears clinically. Nine of these patients were clinically found to have concomitant subcracoid impingement. All patients were subjected to MRI of shoulder. Measurement of the CHI was done in images with humerus in maximal internal rotation. Presence of subscapularis tear was examined intraoperatively. Statistical evaluation of the data was performed using Student’s t-test and Fisher’s exact test and the results were applied to two cohorts of patients. One cohort consisted of patients who had a CHI value of less than 5.5mm and the other cohort had a CHI value greater than 5.5mm. Average CHI values in patients with and without a subscapularis tear were determined. Results Nine patients who had clinical subcoracoid impingement were found to have an average CHI of 5.33mm. All nine of them had an associated tear of subscapularis with long head of Biceps tendon subluxation and/or fraying. Remaining 15 patients had an average CHI of 10.48 and they did not have either signs of Subcracoid impingement or subscapularis tear but had a tear elsewhere (Supraspinatus or Infraspinatus). Difference between these two groups was found highly significant (p-value<0.001). All patients with a CHI value of equal to, or less than 5.5mm had a subscapularis tear, whereas only 11% of patients with a CHI value more than 5.5mm had a tear (p-value<0.001, highly significant). Conclusion Reduction in the CHI has a significant association with rotator interval pathologies such as subscapularis tears and subluxation or fraying of long head of biceps tendon. Treatment of such patients should include modalities such as coracoplasty or anterior shoulder stabilisation. We recommend that clinical evidence of subcoracoid impingement should lead to further Investigation in the form of MRI and estimation of CHI. A CHI of less than 5.5 mm may indicate subscapulais tear in Indian patients. PMID:27790534

    The effectivity of Betadine skin and mucosa disinfectant solution and Betadine hand disinfectant soap (MUNDIPHARMA A. G. and EGIS Pharmaceuticals has been examined in hospitalized patients and hospital employees. The history of the production of polyvynilpyrrolidone-iodine (PVP-Iodine) the mechanism of actions and the biological effects of these products have been discussed. Bacteriological samples were collected from the skin of four regions most frequently used for injection (fossa cubitalis, right and left hands and gluteal region, right and left sides) of 10 hospitalized patients before and after washing these regions with Betadine. The average of 68 microorganisms Colony Forming Unit (CFU) recorded before disinfection decreased below 1 CFU on average in the samples taken after disinfection. From both hands of 6 hospital employees 190 CFUs could be demonstrated following washing hands with the commonly used soap. After washing hands with Betadine soap a total of 1 CFU could be demonstrated. The hands of 44 hospital employees were infected with E. coli of non-pathogenous reference strain whereafter samples were collected. After the disinfection of the hands with Betadine liquid soap samples were taken again. In the samples taken before disinfection an average of 745 CFUs, in samples taken after disinfection an average total of 11 CFUs were found. The results prove the outstanding disinfectant action of the two examined Betadine products.

    The presence of depressive symptomatology in alcoholics has frequently been encountered in clinical practice, but the relationship running between the two pathologies remains a subject for discussion. The methodological difficulty of this evaluation is seen in a major discordance of reported data. Against this background, a group of subjects hospitalized in a neuropsychiatric environment has been assessed for incidence of alcoholic and depressive pathologies and their possible correlations. Of 428 hospitalizations for alcoholism, 350 (82%) presented a depressive pathology. These patients were distinguished by DSM III into three groups [a) adaptation disturbance with depressed mood; b) dysthymic disturbance; c) atypical depression]. Within these groups, the incidence of prior stress-inducing psychosocial events was assessed according to the criterion of growing seriousness of DSM III. The results after statistical processing are discussed and compared with reported data.

    Objective: Henoch-Schonlein purpura nephritis (HSPN) and IgA nephropathy (IgAN) are similar syndromes. We aimed to determine whether the crescent formation/immunocomplex in glomeruli is associated with the differences of the biochemical indexes between HSPN and IgAN. Methods: We investigated the medical records of 137 HSPN cases and 41 IgAN cases from January 2009 to April 2014 in Nanjing Children’s Hospital of Nanjing Medical University. The clinical and pathological data were analyzed and compared between HSPN and IgAN. Results: HSPN patients had markedly higher levels of blood white blood cell (WBC), hemoglobulin (Hb) and platelet (PLT), lower levels of hematuria, blood nitrogen (BUN) and C4 compared with IgAN cases. Crescents formation and C3 deposition in the kidney did not affect these differences. Significantly lower levels of hematuria, blood IgG, IgM and C4 in HSPN compared with IgAN cases were observed among patients with IgG deposition. Markedly higher levels of WBC and Hb, lower levels of hematuria, creatinine (Cr), C4 in HSPN compared with IgAN cases were observed among patients with IgM deposition. No marked differences of the biochemical indexes were noted between HSPN and IgAN cases among patients with C1q deposition. Markedly higher levels of WBC and Hb, lower level of blood C4 in HSPN compared with IgAN cases were observed among patients with fibrogen deposition. Conclusions: The different levels of biochemical indexes at presentation between HSPN and IgAN may be associated with the deposition of IgG, IgM, C1q and fibrogen in the kidney. PMID:26045740

    This study comprises a large psychological investigation of 10 patients with Posttraumatic Sympathetic Dystrophy of hands and compares the results with a control-group. It was found that a "psychosomatic disposition" with three factors completing each other occurs: a neurotic-depressive structure of personality including narcisistic problems, a posttraumatic disorder of adaptation with various emotional traits (as a reaction to the stress of the somatic trauma) and finally a less confidential style of interaction between the medical practitioner and the patient. A supporting psychotherapy is proposed, if necessary combined with a Tranquilizer. The behaviour of the medical practitioner has a prophylactic function. PMID:2474840

    Background: Chemokines are pro-inflammatory cells that can be induced during an immune response to recruit cells of the immune system to a site of infection. Aim: This study was conducted to detect the presence of chemokines, macrophage inflammatory protein-1α (MIP-1α), and 1β (MIP-1β) and estimate their levels in gingival crevicular fluid (GCF) in children with band and loop space maintainers. Materials and Methods: MIP-1α and MIP-1β levels were estimated in GCF samples from twenty healthy children and twenty children with band and loop space maintainers. Periodontal status was evaluated by measuring gingival index, plaque index, and Russell's periodontal index. The GCF samples were quantified by ELISA, and the levels of MIP-1α and MIP-1β were determined. Results: The mean MIP-1α concentrations in healthy children and those with space maintainers were 395.75 pg/µl and 857.85 pg/µl, respectively, and MIP-1β was 342.55 pg/µl and 685.25 pg/µl, respectively. MIP-1α and MIP-1β levels in GCF from children with space maintainers were significantly higher than in the healthy group, and statistically significant difference existed between these two groups. Conclusion: MIP-1α and MIP-1β can be considered as novel biomarkers in the biological mechanism underlying the pathogenesis of gingival inflammation in children with space maintainers. PMID:27630491

    Background: Oral pre cancer and oral cancer results in lipid peroxidation, and assessment of lipid peroxides in body fluids may give insights into the role of anti oxidants in its management. Aim: The study was conducted to discern the varying levels of lipid peroxides in saliva, serum and tissue in oral pre cancer and oral cancer and also various forms of tobacco usage with sex as an added parameter. Materials and Methods: The levels of lipid peroxides were measured in saliva, serum and tissue in a total of 50 patients, 20 belonging to control, and 30 study group in which 10 with oral leukoplakia and 20 with histologically proven oral squamous cell carcinoma (OSCC). The mean value of malondialdehyde (MDA) were also recorded in males and females among the patients with oral leukoplakia and OSCC. Among the study group patients, the levels of MDA were also recorded in habits of smoking and chewing tobacco. Statistical analysis used: Student’s independent t-test, one way ANOVA, Tukey HSD procedure. Results: Significantly elevated levels of lipid peroxides were seen in saliva, serum and tissue in oral leukoplakia and OSCC when compared to control patients. Among the study group, there were statistically significant increased levels of MDA in OSCC when compared to oral leukoplakia. There was also increase in MDA level in patients with smoking and chewing, but the variations seen in males and females were not very significant. Conclusion: The results clearly indicate the increase in lipid peroxidation in oral pre cancer and oral cancer with no significant difference between gender groups. The role of saliva as a relatively risk free and reliable, easy to obtain biofuid for diagnostic purposes has been highlighted. Also, since the levels of antioxidants are drastically decreased in carcinogenesis, the importance of anti oxidant supplements in the early stages of the disease has also been elucidated.

    The present investigation was conducted to study the effects of experimental Clostridium perfringens type D enterotoxaemia in teddy goats. Clinical signs started to appear after 30 min of experimental infection like anorexia, diarrhea, dehydration, frothing and dyspnea. Gross lesions consisted of severe congestion in tissues of varying intensity with enlarged mesenteric lymph nodes while histological examination revealed edema of lungs, kidney, and lymph nodes and to some extent in brain along with hemorrhages in lungs and intestines. Clostridium perfringens type D carrying alpha and epsilon toxin genes were amplified with amplicon size about 247 bp and 665 bp, respectively. Human erythrocytes showed the highest hemolysis, 68%, followed by mice, 57%, against culture supernatants. The percentage of hemolysis was significantly higher at 37°C as compared to 25°C except for rabbit and dog. PMID:27175159

    Non-syndromic pituitary gigantism can result from AIP mutations or the recently identified Xq26.3 microduplication causing X-linked acrogigantism (XLAG). Within Xq26.3, GPR101 is believed to be the causative gene, and the c.924G > C (p.E308D) variant in this orphan G protein-coupled receptor has been suggested to play a role in the pathogenesis of acromegaly.We studied 153 patients (58 females and 95 males) with pituitary gigantism. AIP mutation-negative cases were screened for GPR101 duplication through copy number variation droplet digital PCR and high-density aCGH. The genetic, clinical and histopathological features of XLAG patients were studied in detail. 395 peripheral blood and 193 pituitary tumor DNA samples from acromegaly patients were tested for GPR101 variants.We identified 12 patients (10 females and 2 males; 7.8 %) with XLAG. In one subject, the duplicated region only contained GPR101, but not the other three genes in found to be duplicated in the previously reported patients, defining a new smallest region of overlap of duplications. While females presented with germline mutations, the two male patients harbored the mutation in a mosaic state. Nine patients had pituitary adenomas, while three had hyperplasia. The comparison of the features of XLAG, AIP-positive and GPR101&AIP-negative patients revealed significant differences in sex distribution, age at onset, height, prolactin co-secretion and histological features. The pathological features of XLAG-related adenomas were remarkably similar. These tumors had a sinusoidal and lobular architecture. Sparsely and densely granulated somatotrophs were admixed with lactotrophs; follicle-like structures and calcifications were commonly observed. Patients with sporadic of familial acromegaly did not have an increased prevalence of the c.924G > C (p.E308D) GPR101 variant compared to public databases.In conclusion, XLAG can result from germline or somatic duplication of GPR101. Duplication of GPR101 alone is sufficient for the development of XLAG, implicating it as the causative gene within the Xq26.3 region. The pathological features of XLAG-associated pituitary adenomas are typical and, together with the clinical phenotype, should prompt genetic testing. PMID:27245663

At stage I discirculatory encephalopathy subjective complaints predominated, being caused by syndrome of thoracic outlet, steal syndrome, stenosing lesions of brachiocephalic arteries. Encountered more frequently in the middle-aged and elderly patients were affections of several major brain arteries. Specific weight of correlation between ultrasonic investigation and angiography in stenosing lesions of brachiocephalic arteries in patients with discirculatory encephalopathy constituted 84-100%. Therefore patients with discirculatory encephalopathy of atherosclerotic genesis require ultrasonic investigation of brachiocephalic arteries with the purpose of finding out exactly the pathological process and choosing the tactics of treatment.

    A group of 12 patients with recent acute hepatitis (8/86 with HVB and 4/22 with alcoholic hepatitis) had a rapid evolution (under 2 years) towards hepatic cirrhosis (early H.C.). The clinical-biological, immunological and morphological study made evident several characteristics, which became predictive markers of the early cirrhotic evolution of acute hepatitis. Clinically, a persistence of dyspeptic disorders and appearance of several systemic manifestations is noticed. Biologically, the maintenance of some increased transmainases, variable bilirubinemia and decrease of serinemia. Immunologically, the transfer of IgM towards increased IgM, the decrease of the total T lymphocyte and of T1 substrate, the increase of the active B and T lymphocyte. The morphologic exploration is decisive for specification of the diagnosis in the early hepatic cirrhosis. PMID:1982190

    Metastatic tumors involving salivary glands arising from the non-head and neck area are very rare. Renal cell carcinoma (RCC) is known for its high propensity for metastasis to unusual localizations. RCC metastasis to the maxillofacial area is an uncommon event (16%), but metastasis to salivary glands is extremely rare. We report a series of 9 such cases retrieved from two institutions. The group included 6 females and 3 males. The age at diagnosis ranged from 60 to 97 years (mean 72.6 years). The tumors involved the parotid gland in 7 cases, and the submandibular and small salivary gland of the oral cavity in 1 case each. The size of tumors ranged from 0.4 to 5 cm. Total parotidectomy with selective neck dissection was performed in 4 cases, while superficial parotidectomy was performed in 1 case and simple resection in 3 cases. Histologically, all the tumors were clear cell renal cell carcinomas, and therefore the differential diagnosis mainly included clear cell variants of salivary gland carcinomas. The parotid gland was the initial manifestation of renal malignancy in 4 of the cases, while in the remaining 5 cases a history of RCC had been known. The salivary gland involvement developed from 11 months to 13 years after the time of diagnosis of the primary tumor. In 2 cases it was the first site of dissemination. Pathologists need to maintain a high index of suspicion for the possibility of metastasis when confronted with oncocytic or clear cell neoplasms developing in salivary glands. RCC, although rare, should be included in this differential diagnosis. PMID:27179273

    Many studies have been made of pulpal reactions to pulp protection (lining) materials have always employed a smear layer between the dentin wall and the lining materials. In this study, the author has attempted to evaluate pulpal response without a smear layer and compared effects of pulp protection (lining) with and without smear layers. Materials and methods. The experiment employed 84 vital human teeth ranging in age from 14 to 54 years. The experimental teeth were divided into 4 groups for the purposes of histopathological studies and scanning electron microscope (SEM) observation. Group C: No EDTA-treatment and lining with gutta-percha temporary material, 10 cases for histopathological study and 4 cases for SEM observation. Group TC: EDTA-treatment and lining with gutta-percha temporary material, 10 cases for histopathological study and 4 cases for SEM observation. Group P: No EDTA-treatment and lining with Protect Cement. 20 cases for histopathological study and 8 cases for SEM observation. Group TP: EDTA-treatment and lining with Protect Cement. 20 cases for histopathological study and 8 cases for SEM observation. After local anesthesia, Black's simple class I cavities were made in the experimental teeth with a diamond instrument mounted on a high-speed air turbine at room temperature with a water spray coolant. In Groups TC and TP only, an aqueous solution of 0.5% EDTA (pH 7.4) 10 ml was applied from cavity floor to dentin for 60 seconds. All cavities were then washed with distilled water, and the dentin was dried with an air stream. The floor of cavities were lined with thin layers of the following materials: Group C and TC, gutta-percha temporary material (G-C Dental Industrial Co., Tokyo, Japan).

    Objectives: This study was conducted to assess the clinic-epidemiological profile of snakebite cases admitted at a Tertiary Care Centre in South India. Materials and Methods: A record based retrospective study was carried out at Kasturbha Medical College affiliated hospitals in Mangalore. All the snakebite cases admitted to the hospitals from January 2007 to December 2011 were included in the study. Data were collected using a pretested semi-structured questionnaire and analyzed using Statistical Package for Social Sciences (SPSS version 11.5). The results are expressed as percentages. Results: The study included 198 cases of snakebite victims. The majority of the cases were males (68.2%). The mean age of the study population was 34.8 years. Maximum numbers of snakebite cases were reported during the month of September to December (47.9%). The peak time of snakebite was between 18.01 and 24.00 h which was reported in 40.5% of the cases. Lower extremities were the most common site of bite in more than three-fourth of the cases (80.9%). The most common symptoms were a pain (45.9%) and swelling (44.9%). The case fatality rate was observed to be 3.0%. Conclusion: Snakebite still remains a major public health problem in this part of the world. Knowledge must be imparted regarding the prevention of snakebites through community health programs. Messages regarding prompt reporting of such cases and importance of effective treatment must be disseminated among people through mass media and role plays. PMID:26862263

    Aim: The present study was undertaken to study the pathology and control of sudden unexplained mortality in wistar rats. Materials and Methods: This study was conducted in a colony of 25 male wistar rats where there was mortality of nine rats. The dead rats were subjected to thorough post-mortem examination and necropsy samples were processed for hematoxylin and eosin staining for histopathological studies. Faecal samples of live rats were studied for the presence of parasitic eggs. Treatment with anthelmintics was given to manage the mortality and infections. Results: The investigation revealed a natural co-infection of Cysticercus fasciolaris and Hymenolepis diminuta in wistar rats, which were pathogenic enough to cause mortality. Typical lesions associated with the parasites were found in the dead rats. The mortality and infection were managed with common anthelmintics. Conclusion: C. fasciolaris and H. diminuta infection can cause mortality in wistar rats even when individually they cause asymptomatic infection. The mortality and infection can be managed with common anthelmintics. PMID:27047007

    RIASSUNTO. Scopo. Descrivere il management di un paziente con malattia di Marchiafava-Bignami (MBD) associata a lesioni frontali corticali, senza sintomi specifici al primo accesso in Pronto Soccorso, e insorgenza tardiva di sintomi psichiatrici atipici. Metodi. Descriviamo il caso di un paziente di 44 anni con storia di abuso cronico di alcol, a cui è stata diagnosticata la MBD. Risultati. La risonanza magnetica ha evidenziato lesioni nello splenio e corpo del corpo calloso e lesioni bilaterali della corteccia frontale. Il paziente ha sviluppato sintomi psichiatrici atipici a insorgenza tardiva, che sono risultati essere resistenti alle terapie farmacologiche impostate. Discussione. Il caso che descriviamo sembra supportare le attuali, ma ancora scarse evidenze che descrivono il coinvolgimento corticale nella MBD, suggerendone l'associazione con una prognosi peggiore. I sintomi psichiatrici possono risultare difficili da trattare a causa della resistenza alle terapie. Conclusione. Il coinvolgimento di psichiatri, radiologi e neurologi secondo un approccio di consultazione-liaison si è dimostrato di fondamentale importanza per la diagnosi e l'impostazione della terapia adeguata al paziente.

    Introduction: Tuberculosis (TB) is one of the leading causes of death and disease worldwide. Tobacco smoking has been linked as a risk factor for TB. This study was aimed to affirm the strength of association between smoking and pulmonary TB. Materials and Methods: Pulmonary TB patients aged between 18 and 65 years were enrolled and followed-up until treatment completion. Two consecutive sputum smears were examined from each patient for the presence of acid-fast bacilli (AFB) using Ziehl–Neelsen technique. Radiological severity of disease was assessed using guidelines of National TB Association of USA. Sputum smears for AFB were graded for positivity as per WHO Revised National TB Control Programme criteria. Response was determined in terms of sputum conversion at the end of intensive phase and final treatment outcomes. Results: Sputum smear grading of 3+ increased from 12.5% to 68.18% and 66.66% as smoking index increased from <100 to 100–299 and >300 (P < 0.05). In nonsmokers, 79.2% patients had minimal disease while only 4.2% had advanced disease as compared to smokers where 52.4% had moderate disease, 26.2% advanced disease, and 21.4% minimal disease (P < 0.01). Smokers had significantly lower treatment success rate (69%) as against nonsmokers and former smokers (93.8% and 90.9%, respectively, P = 0.001) owing to a higher default rate among smokers (28.5%) than nonsmokers (6.3%) and former smokers (9.1%). Conclusion: Smokers during initial presentation, as well as at end of the treatment demonstrate more radiological findings, cavitary disease, and worse sputum AFB smear grading. Smokers also have a poorer treatment success rate largely due to high percentage of default rate thus suggesting noncompliance as a main confounder to treatment success. Focus needs to be made to reduce defaulters which are more common among smokers.

    Some patients with immunoglobulin paraproteinemic neuropathy have intra-nerve deposits that morphologically mimick amyloid, but do no stain with Congo red. Patients with amyloid-like deposits were identified. The nerve amyloid-like aggregates were studied by laser microdissection and dual mass spectrometry. Three male patients, all with IgM gammopathy, and neuropathy were identified. Follow-up, disease duration was 5, 19, and 7 years, respectively. All had progressive asymmetric sensory-onset distal axonal polyneuropathy with late motor involvement. Autonomic symptoms occurred in only one after 13 years of symptoms. None had clinical cardio-renal involvement. One had skin papules with dermal amyloid-like deposits. Endoneurial amyloid-like deposits had granulo-fibrillar ultrastructure. Mass spectrometry of laser-dissected deposits identified IgM pentameric macroglobulin (heavy, light, and joining chains) without amyloid-associated proteins including absent apolipoprotein E and serum amyloid P-component. Amyloid-like neuropathy has distinct clinical, pathologic, and proteomic features which expand the spectrum of IgM neuropathies. Patients have favorable survival, relative absence of autonomic features, and distinct proteomic profiles of the infiltrative protein in nerve. PMID:22734903

    Introduction According to the World Health Organization (WHO), mental health disorders are one of the leading causes of disability worldwide and it is as common in children. Anywhere between one to three children may be suffering from psychiatric disorders at any point in time. Aim This study intended to find the pattern of psychiatric disorders and associated sociodemographic factors among children attending the psychiatric department in a tertiary care hospital in Southern India. Materials and Methods An analysis was conducted of patients who attended the psychiatric clinic from April 2012 to March 2013. Disorders were classified according to International Classification of Diseases, 10th edition (ICD-10) criteria. Data obtained was analysed by SPSS 11.5 version. Chi-square test was used to see association and p<0.05 was taken as significant. Results The mean age of the children was 10.9 years (SD=4.3). Predominance of males was noticed. It was seen that the male children, mostly suffered from Pervasive and specific developmental disorders (n=105; 31.1%). While in the female children, a prominence of anxiety, dissociative, stress-related, somatoform and other non-psychotic mental disorders was seen (n=52; 27.1%). Co-morbidity of psychiatric disorders was seen with intellectual disability and a seasonal predominance of psychiatric disorders was seen during autumn. Conclusion Children presenting with psychiatric disorders in the hospital showed a wide age range and among them, males outnumbered females. Psychiatric disorders showed seasonal variation and the types of disorder varied significantly with age, gender and religion. PMID:27134978

    Breast involvement by non-Hodgkin lymphomas is rare, and exceptional for T-cell lymphomas; we studied the morphologic, immunophenotypic, and clinical features of 11 patients with T-cell non-Hodgkin lymphomas involving the breast. Four cases fulfilled the definition criteria for primary breast lymphomas, 3 females and 1 male, with a median age of 51 years. One primary breast lymphomas was T-cell lymphoma unspecified, other was subcutaneous panniculitis-like T-cell lymphoma, and 2 cases were anaplastic large cell lymphomas. One of the anaplastic large cell lymphoma cases was found surrounding a silicone breast implant and presented as clinically as mastitis; whereas the other case occurred in a man. T-cell lymphoma secondarily involved the breast in 7 patients, all women and 1 bilateral, with a median age of 29 years. These secondary breast lymphomas occurred as part of widespread nodal or leukemic disease. Three patients had adult T-cell leukemia/lymphoma, including the patient with bilateral lesions, 3 others had precursor T-lymphoblastic lymphoma/leukemia, and the other presented with a peripheral-T-cell lymphoma non otherwise specified type. Breast T-cell lymphomas are very infrequent and are morphologically and clinically heterogeneous.

    In recent years it has become evident that ABC transporters fulfill important barrier functions in normal organs and during disease processes. Most importantly, resistance to drugs in cancer cells led to intense oncological and pharmacological investigations in which researchers were able to highlight important pharmacological interactions of chemotherapeuticals with ABC transporter function. Recently, the development of neurodegenerative diseases and the maintenance of neuronal stem cells have been linked to the activity of ABC transporters. Here, we summarize findings from cell culture experiments, animal models and studies of patients with Alzheimer’s disease. Furthermore, we discuss pharmacological interactions and computational methods for risk assessment. PMID:18690837

    Background: Pasteurella multocida a Gram-negative bacterium has been identified as the causative agent of many economically important diseases in a wide range of hosts. Hemorrhagic septicemia is a disease caused by P. multocida serotype B:2 and E:2. The organism causes acute, a highly fatal septicemic disease with high morbidity and mortality in cattle and more susceptible in buffaloes. Therefore, the aim of this study was to investigate the clinical signs, blood parameters, post mortem and histopathology changes caused by P. multocida Type B:2 infections initiated through the oral and subcutaneous routes. Methods: Nine buffalo heifers were divided equally into 3 treatment groups. Group 1 was inoculated orally with 10 ml of phosphate buffer saline; Groups 2 and 3 were inoculated with 10 ml of 1012 colony forming unit of P. multocida Type B:2 subcutaneously and orally respectively. Results: There was a significant difference (p<0.05) in temperature between the subcutaneous and the control group. The results revealed significant differences (p<0.05) in erythrocytes, hemoglobin, packed cell volume, leukocytes, monocytes, and A: G ratio between the subcutaneous and the control group. Furthermore, there were significant differences (p<0.05) in leukocytes, band neutrophils, segmented neutrophils, lymphocytes, eosinophils, basophils, thrombocytes, plasma protein, icterus index, gamma glutamyl tranferase and A: G ratio between the oral and the control group. The post mortem lesions of the subcutaneous group buffaloes showed generalized hyperemia, congestion and hemorrhage of the immune organs, gastro-intestinal tract organs and vital organs. The oral group buffaloes showed mild lesions in the lung and liver. Histologically, there were significant differences (p<0.05) in hemorrhage and congestion; necrosis and degeneration; inflammatory cells infiltration; and edema in between the groups. Conclusion: This study was a proof that oral route infection of P. multocida Type B:2 can be used to stimulate host cell responses where oral vaccine through feed can be developed in the near future.

    This prospective study was conducted on 15 animals (eight buffaloes and seven cows), diagnosed with late pregnancy indigestion. Ten buffaloes and 10 cows served as the control group. The animals were in advanced pregnancy and had partial or complete anorexia, reduced water intake, loss of defecation or scanty faecal output, and mild to moderate dehydration. Heart and respiration rates were increased and rumen motility was reduced. Five animals had persistent tympany and moderate distension of left abdomen, and two animals each had bilateral abdominal distension and papple shaped abdomen. Neutrophil and lymphocyte counts were significantly higher and lower than the control values. Total bilirubin, AST, total protein, globulin, BUN, glucose, and lactate were significantly higher, and chloride and calcium were significantly lower than the control values. Levels of ALP, GGT, albumin, creatinine, cholesterol, triglyceride, fibrinogen, fibrinogen ratio, sodium, potassium, phosphorus, and magnesium did not differ significantly from the control values. Rumen chloride concentration was higher than the reference range. Majority of animals were managed symptomatically until parturition. There was no effect on fetal survival or milk yield in current and subsequent lactation. So, late pregnancy indigestion causes clinical and hemato biochemical alterations which require special consideration when treating diseased animals.

    Analysis of the severity of the clinical course of tick-borne encephalitis (TBE) in the Maritime Territory, 1966-1983, showed a decline in the incidence of the disease by 20% in the group of subjects vaccinated against TBE, whereas the severity of the disease showed no statistically significant difference from that among nonvaccinated subjects. The causes of the poor protective effect of the liquid tissue culture vaccine produced by the Research Institute of Vaccines and Sera, Ministry of Health of the USSR, Tomsk, were demonstrated alongside with the advantages of the lyophilized concentrated vaccine manufactured by the Institute for Poliomyelitis and Viral Encephalitides of the USSR Academy of Medical Sciences, which should be used for prophylactic vaccinations of subjects working in forests who comprised 29% of the vaccines. In this way, TBE incidence in the region could be reduced considerably.

    Analysis of the data of the statistical accounting, mass examinations of the population, observation over the clinical course of the disease and review of the autopsy material attest to the high prevalence of AB and BA in the Southern and South-Eastern parts and the low one in the Western and Northern parts of the republic as well as to their greatest prevalence among the newcomers of the cities. In the newcomers, BA was characterized by its incidence among those over 45 years of age, by the rarity of ABA, predominance of the disease of medium gravity. Meanwhile among the indigenous population, the incidence of IABA, primarily grave course and BA incidence in persons of the young and mature ages were recorded. The lethal outcomes were mainly registered in winter and summer.

    Twelve cases of monomorphic adenoma of the salivary glands were histologically reclassified and their immunohistochemical reactivity for S-100 and cytokeratin was correlated. All patients underwent a benign clinical course. Individual tumors were well encapsulated and frequently showed a focal cystic change. Histologically, 9 cases were of the epithelial basaloid cell type and 3 cases were of the myoepithelioma variant. About one half of the epithelial type featured a mixture of trabecular and tubular patterns. The immunoreactivity to S-100 and cytokeratin varied. All basaloid cell adenomas were positive for cytokeratin, while S-100 positivity was found mostly in the stroma along with the varied reaction and intensity in the epithelial nests. In myoepitheliomas, cytokeratin was totally negative and S-100 was positive in 2 of 3 cases. The above findings suggest that the degree of participation of myoepithelial cells determines the phenotypic expression of monomorphic adenomas, and supports the hypothesis that the basaloid cell and myoepithelial types may be located on extreme ends of the same tumor spectrum with a wide range of pleomorphic adenoma in-between.

    Introduction Oral squamous cell carcinoma (OSCC) ranks 12th most common cancer in the world. Objective The aim of this study was to retrospectively evaluate the OSCC. Methods A retrospective study of 611 OSCC patients from January 2010 to December 2013 was carried out in Department of Surgical Oncology, King George's Medical University, Lucknow, India. Details of patient's sex, age, tobacco habit and site of cancer were noted. Data were analyzed by Student's t test and chi-squire (χ2) test. Results The prevalence of OSCC was significantly (p < 0.001) higher in males (75.9%) than females (24.1%). The mean age of female patients was higher than males (p < 0.001). In both the genders, the buccal mucosa and gingivobuccal sulcus were found to be the most affected sites. Moreover, the smokeless form of tobacco was found to be significantly associated with OSCC, especially in females. Conclusion The study concluded that OSCC is more common in men as compared to women, probably due to habit of tobacco consumption. Smokeless tobacco use is an important risk factor, especially in females. PMID:26937366

    Haemorrhagic septicaemia is a disease caused by Pasteurella multocida serotype B: 2 and E: 2. The organism causes acute, highly fatal septicaemic disease with high morbidity and mortality in cattle and more susceptible in buffaloes. Lipopolysaccharide can be found on the outer cell wall of the organism. Lipopolysaccharide is released during multiplication which leads to inflammatory reaction. It represents the endotoxin of P. multocida type B: 2 and responsible for toxicity in haemorrhagic septicaemia which plays an important role in the pathogenesis of the disease. Therefore, the aim of this study was to investigate the clinical signs, blood parameters, gross post mortem lesions and histopathology changes caused by P. multocida type B:2 immunogen lipopolysaccharide infections initiated through intravenous and oral routes of infection. 9 buffalo heifers were divided equally into 3 treatment groups. Group 1 was inoculated orally with 10 ml of phosphate buffer saline (PBS); Group 2 and 3 were inoculated with 10 ml of lipopolysaccharide broth intravenously and orally respectively. For the clinical signs, there were significant differences (p < 0.05) in temperature between the control, intravenous and oral group. In hematology and biochemistry findings, there were significant differences (p < 0.05) in erythrocytes, haemoglobin, PCV, MCV, lymphocytes, monocytes, eosinophils, GGT and albumin between the control, intravenous and oral group. However, there were no significant differences (p > 0.05) in the MCHC, leukocytes, band neutrophils, basophils, thrombocytes, plasma protein, icterus index, total protein, globulin and A:G ratio between intravenous and oral group. For Group 2 buffaloes, there were gross lesions in the lung, trachea, heart, liver, spleen, and kidney. In contrast, lesions were only observed in the lung, trachea and liver of Group 3 buffaloes. There were significant differences (p < 0.05) in hemorrhage and congestion; necrosis and degeneration; and inflammatory cells infiltration between experimental groups and control group. However, there were no significant differences (p > 0.05) in edema lesion between groups. In conclusion, this study is a proof that oral route infection of P. multocida type B:2 immunogen lipopolysaccharide can be used to stimulate host cell responses where oral vaccine through feed could be developed in the near future.

    Objectives: Wrightia antidysenterica Linn. (WA) is male variety Kutaja stated to be potent therapeutic emetic agent in skin disorders. Expulsion of doshas through oral route is termed as Vamana Karma (VK) (therapeutic emesis). However, so far, its utility for Vamana is not explored in detail, therefore there is a need to revalidate the utility of WA for Vamana. Hence, the above study was conducted to ascertain the efficacy as a therapeutic emetic agent (vamaka yoga) in the management of psoriasis along with quality control and standardization of this herb. Materials and Methods: The drug was standardized as per analytical procedures in Pharmacopeias. Thirty patients of psoriasis fulfilling inclusion criteria were taken for the study and Vamana with WA was conducted. Criteria were prepared to assess the signs and Symptoms of psoriasis. VK was assessed using the classical Lakshanas (features) such as Anthiki shudhi (Ending symptoms of emesis), Vaigiki shudhi (features of vomiting bouts), Maniki shudhi (Quantitative and qualitative purification), complications. Result: VK with WA showed significant relief in parameters of psoriasis such as scaling, itching, candle grease sign (P < 0.001), and psoriasis area and severity index score (P = 0.001). In VK with WA, mean number of Vegas (vomiting bouts) was 6.91. 66% patients showing quantitative purification between 301 and 600 ml. 73.33% showed all Symptoms of purification. 73.33% patients showed Kaphanta vamana (Moderate expulsion of desire humor). In the level of biopurification, 66.66% patients showed moderated purification. No complication was noted with moderate drug palatability. Conclusion: Pharmacopeial analytical study showed its standardized values for testing the drug used for the study. It is proved as potent therapeutic emetic agent with no complication showed its clinical benefits over skin disorder like psoriasis. SUMMARY Seeds of Wrightia antidysenterica (WA) Linn. free from any foreign matter were selected for the study. Loss on drying revealed 6.535% moisture content; total ash indicating of total inorganic content was found to be 5.12%; acid insoluble ash is the acid insoluble part of total ash, mainly silica, WA showed 0.393% acid insoluble ash; ethanol and water soluble extractive is indicative of percentage active constituents were found to be 25.66 and 20.854%, respectively. High-performance thin layer chromatography fingerprinting profiles of WA under 254 nm showed the presence of 7 spots (all in green) at Rf values ranging from 0.21 to 0.88. Under 366 nm there were 4 prominent spots (all in fluorescent) at Rf 0.49 to 0.82 and, when scanned under white light 620 nm following derivatization with vanillin sulfuric acid 6 spots (in different colors) were evident at Rf 0.28 to 0.58. Among these spot with Rf of 0.58 was common when visualized under all the three methods. Rf values by densitometric scan of WA showed 12 peaks at 254 nm and 5 peaks at 366 nm. However, in clinical trial, it was found to be a potent emetic agent without any complication.

    In recent years, stings of a lethal scorpion species were recorded from Jaffna Peninsula in the northern dry zone of Sri Lanka. This species was identified as Hottentotta tamulus (Scorpiones: Buthidae) which is the Indian red scorpion commonly found in Maharashtra, India. The Teaching Hospital, Jaffna recorded 84 H. tamulus stings over a year in 2012 and of them, 23 cases provided offending scorpions (proven cases). Three localities in Jaffna were recorded as hotspots of scorpion stings namely Palali, Achchuvali and Karainagar. Of the proven cases, 13 (57%) and 10 (43%) were males and females respectively and had a mean age of 30 years (SD ± 20 years). Among them, 5 (22%) were children below 12 years. In 13 (57%) patients stings occurred inside their houses including two children (40%). Six (26%) stings occurred at night when the victims were in sleep. Median time taken to arrive at the hospital from the time of stinging was 58 min (range 8-550 min). Signs of over activation of autonomic nervous system predominated the clinical picture-tachycardia in 14 (61%), high blood pressure in 11 (48%), excessive sweating in 9 (39%), excessive salivation in 5 (22%), hypotension in 4 (17%) and piloerection in 3 (13%). Children showed higher predilection to develop tachycardia - 4 (80%) and excessive salivation - 3 (60%). Priapism was not observed and 17 (74%) patients have developed intense pain at the site of sting. The commonest ECG change was tachycardia (73%) and occasional T wave inversion. Prazosin as a treatment was given to 22 (96%) patients. All patients made recovery and 13 (57%) patients left the hospital within two days. In future, there is a potential risk of spreading this species to elsewhere in the country and may disturb the ecological balance.

    Introduction Case reports pertaining to Magnetic Resonance Imaging (MRI) diagnosis of en-plaque tuberculoma are limited. To the best of our knowledge, descriptions about en-plaque tuberculoma are limited to few isolated case reports. This paper comprehensively depicts the clinical and radiological features in such patients and may serve not to miss this uncommon manifestation of a common central nervous system infection. Materials and Methods A descriptive documentation of the patient cohort with a detailed history and neurological examination were carried out in all the patients. All underwent MRI Brain which revealed en-plaque tuberculoma. Relevant investigations including Cerebrospinal Fluid (CSF) were done in all patients. CSF Polymerase Chain Reaction (PCR) was done in all. Results Eight adult patients (two women and six men) with MRI showing en-plaque CNS tuberculoma were seen during a period of five years. None had suffered from TB in the past nor had history of contact with tuberculosis. All patients demonstrated extra axial dural based lesions and none had cerebral ooedema, parenchymal lesions, mass effect or midline shift. The lesions were located in bilateral corresponding regions in two patients and the rest six had unilateral lesions. Seven patients had lesions located in the supratentorial compartment; one had lesion extending to the infratentorium along the tentorium cerebelli. Various patterns of enhancement were noted in our patients: thin peripheral (n=3), homogenous (n=3), varied enhancement (n=1) and open ring enhancement (n=1). CSF Polymerase Chain Reaction (PCR) was tested positive for tuberculosis in all of our patients. Conclusion While MRI provides an understanding of the topography of the lesion, PCR helped in establishing the diagnosis of tuberculosis in our patients. Awareness about en-plaque tuberculomas can heighten the index of suspicion and can thus prevent aggressive surgical resections and thereby reduce mortality and morbidity. PMID:27504326

    Diabetic foot infections (DFIs) constitute a major complication of diabetes mellitus. DFIs contribute to the development of gangrene and non-traumatic lower extremity amputations with a lifetime risk of up to 25%. The aim of the present study was to identify the presence of neuropathy and determine the ulcer grade, microbial profile and phenotypic and genotypic prevalence of the methicillin-resistance gene mecA and extended spectrum β-lactamase (ESBL)-encoding genes in bacterial isolates of DFI in patients registered at the Pakistan Institute of Medical Sciences (Islamabad, Pakistan). The results indicated that 46/50 patients (92%), exhibited sensory neuropathy. The most common isolate was Staphylococcus aureus (25%), followed by Pseudomonas aeruginosa (P. aeruginosa; 18.18%), Escherichia coli (16.16%), Streptococcus species (spp.) (15.15%), Proteus spp. (15.15%), Enterococcus spp. (9%) and Klebsiella pneumoniae (K. pneumoniae; 3%). The prevalence of the mecA gene was found to be 88% phenotypically and 84% genotypically. K. pneumoniae was shown to have the highest percentage of ESBL producers with a prevalence of 66.7% by double disk synergy test, and 100% by the cefotaxime + clavulanic acid/ceftazidime + clavulanic acid combination disk test. P. aeruginosa and K. pneumoniae had the highest (100%) proportion of metallo β-lactamase producers as identified by the EDTA combination disk test. The overall prevalence of β-lactamase (bla)-CTX-M, bla-CTX-M-15, bla-TEM, bla-OXA and bla-SHV genes was found to be 76.9, 76.9, 75.0, 57.7 and 84.6%, respectively, in gram-negative DFI isolates. The prevalence of mecA and ESBL-related genes was found to be alarmingly high in DFIs, since these genes are a major cause of antibiotic treatment failure. PMID:26998033

    The study included 52 patients after gastrectomy for carcinoma of the proximal part of the stomach. Endoscopic laser therapy was made in 32 patients to reduce inflammation in the anastomosis zone 2-3 weeks after surgery. Drug therapy was made in 20 patients within the same time period. Histochemical study of the biopsy material of esophageal and intestinal part of the anastomosis was carried out. It is revealed that application of copper vapor laser early after surgery reduces edema and inflammation in the anastomosis zone for 2 weeks as well as accelerates the growth of granulation tissue forming a delicate scar thus preventing formation of scar stenosis.

    A clinical and epidemiological study of opisthorchiasis foci in the Yamalo-Nenets Autonomous Okrug was carried out. 764 people were surveyed, including 473 aborigines of the north, 207 denizens, and 84 migrants. Opisthorchiasis infection rate in villages was 40.5-45.7%. The intensity of infection was lower than 200 eggs per g faeces. The modelling of opisthorchiasis prevalence performed after Muench showed the highest correlation with the "simple" and "reversible" models. Factors determining the infection spread and limiting its intensity and those influencing the effect of chemotherapy were defined. Theoretically determined radical suppressive low-dose praziquantel chemotherapy was carried out. The efficacy of the drug, 25, 30, 40 and 50 mg/kg, varied from 76.5 to 92.0% (mean 88.1%), and the decrease of the egg density was more than 60%. The incidence of side effects of the therapy averaged 45.3%.

    Background: One-stage nonsubmerged protocol which can achieve success rates comparable to implants placed in a two-staged submerged procedure also the preconditions for periimplant bone regeneration has lead to more refined concepts of implant loading. Materials and Methods: Twenty sites with single missing tooth were included in this study. Clinical parameters included sulcus bleeding index (sBI), probing pocket depth (PD), and papilla index (PI) and radiographic parameters included crestal bone level were assessed for a period of 9 months. Results: The crestal bone loss showed mean value ranging from baseline 0.25 ± 0.11 to 0.31 ± 0.08 at 3 weeks, to 0.67 ± 0.13 at 3 months, to 0.85 ± 0.09 at 6 months, and to 0.88 ± 0.12 at 9 months. Probing PD, the mean value for probing PD at 3 weeks 1.20 ± 0.83, 3 months 1.60 ± 1.1, at 6 months 1.40 ± 1.14, and at 9 months 1.20 ± 1.0. sBI, mean value for sBI at 3 weeks 0.00 ± 0.00, 3 months 0.3 ± 0.11, at 6 months 0.09 ± 0.25, and at 9 months 0.08 ± 0.24. PI, showed a significant difference among at different points of time with P = 0.000. Conclusion: The dental implants showed <1 mm of crestal bone loss at 9 months follow-up, clinically significant marginal bone loss occurred between the time of implant placement and 3 months. Subsequent to that, bone loss observed around the implant up to 9 months was minimal. The periimplant soft tissue maturity was maintained throughout the study. PMID:27041836

    Background: The peri-implant mucosa undergoes surgical and bacterial assaults in various stages of implant therapy, however, the literature on changes occurring in the peri-implant mucosa is minimal. This study was thus conducted to evaluate the change in the peri-implant mucosal thickness and its effect on the marginal bone levels around dental implants treated in a conventional two-stage implant therapy. Materials and Methods: A total of 36 implants were placed in 22 subjects. Two subjects dropped out. Thirty-three implants in 20 subjects were then evaluated. Initial mucosal thickness, marginal bone levels on radiographs, pain, and exudation were evaluated. All these parameters were recorded at the time of implant placement, at the time of cementation of final restoration, 6 months and 12 months post cementation/restoration. Results: The peri-implant mucosal thickness reduced from implant placement to second stage and till restorations and was statistically significant, in both the thick and thin biotypes, however, at 12 months there was a rebound of the tissue thickness, which was more in the thick biotype (P < 0.05). At 1-year follow-up, there was a reduction in the marginal bone levels, which was more in the thick biotype as compared to the thin biotype (P < 0.05). Conclusion: The mucosa at implant sites undergoes a reduction in thickness from the time of implant placement till the placement of final restorations. The placement of the final restorations and then end of active therapy leads to a rebound of the tissue thickness. Sites with thicker tissues preoperatively have a lesser bone loss and better rebound as compared to thinner tissues. PMID:26941514

    MRSA infection or colonization developed in eleven patients with neoplastic disease including malignant lymphoma (5 cases), soft tissue sarcoma (2 cases), acute myeloblastic leukemia (one), myelodysplastic syndrome (one), multiple myeloma (one), and mesothelioma (one) at our ward from October to December 1999. The infections were pneumonia (six cases), enteritis (three), bacteremia (one), and wound infection (one). Ten of 11 cases received antimicrobial agent (s) during one month before isolation of MRSA, suggesting selection of MRSA. Five cases improved and survived, but six cases died of infection. At the isolation of MRSA, the neutrophil count (NC) of the alive cases was 1, 500/microliter or more but the NC of five cases who died was less than 1,000/microliter, especially less than 100/microliter in three cases who had just received a cancer chemotherapy. Pulsed-field gel electrophoresis, performed in 9 cases, showed an identical DNA-pattern of MRSA in 7 cases, indicating a nosocomial infection. Our method to prevent spread of MRSA targeting solely the patients with MRSA infection was obviously unsatisfactory. We should target also the cases of MRSA colonization and make an effort to wash hands more vigorously. Furthermore, radical reformation such as increasing single sick-rooms drastically and increasing the number of nursing staff is also required.

    Gastric cancer (GC) is a major health problem worldwide and is one of the ten most commonly diagnosed cancers in Jordan. GC is usually diagnosed at late aggressive stages in which treatment options are limited. Recently, heat shock proteins (HSPs) found to be overexpressed in a wide range of malignancies have been considered as promising candidate biomarkers for GC. The aim of this study was to investigate pathogenic roles of a panel of cytosolic HSPs including HSP90, HSP70, HSP60 and HSP27 in GC. Immunohistochemistry was used to assess the level of expression of these proteins in archived tumor samples (N=87) representing various pathological characteristics of GC. HSP90, HSP60 and HSP27 were expressed abundantly in gastric tumors. On the other hand, HSP70 was reduced significantly and was also found to be associated with Helicobacter pylori infection in tissues collected from GC patients. Furthermore, HSP27 was found to be associated with the level of differentiation. Our findings indicate a role of HSP70 as a potential prognostic biomarker, patients harboring positive HSP70 expression displaying worse disease free survival than those with negative HSP70 expression. Differential expression of HSPs may play crucial roles in the initiation and progression of GC, and could be exploited as future therapeutic targets. PMID:27644641

    146 patients (62 female, 84 male) with chronic hepatitis B were regularly examined in 1 to 2 year intervals with an average follow-up period of 12 years (means). Each time patients were evaluated by physical examination, routine laboratory data, immunological and serological testing, ultrasonography, and laparoscopy and/or percutaneous liver biopsy. No patient of the study underwent immunosuppressive or antiviral treatment at any time. The average time data in years and months are given as the median value (mean). Frequency and date of seroconversion from HBeAg to anti-HBe after the first diagnosis of HBV-infection: in patients with chronic persistent hepatitis (CPH) in 79% of cases after 8 years, in patients with chronic active hepatitis (CAH) in 72% of cases after 7 years, and in patients with liver cirrhosis in 61% of cases after 9 years. The overall seroconversion rate in all patients with chronic hepatitis B amounted to 68% 8.5 years after the first diagnosis of HBV-infection. Clinical and prognostic significance: The seroconversion from HBeAg to anti-HBe mostly led to substantial and sustained biochemical and histologic resolution of liver disease activity. In patients with CPH in 100% of cases after 15 months, in patients with CAH in 87% of cases after 17 months, and in patients with liver cirrhosis in 64% of cases after 2.5 years. 80% of these patients with seroconversion and histologic recovery remained HBV-DNA (PCR)-positive.

    Fine-needle aspirationbiopsy (FNAB) is now widely accepted as a diagnostic modality for the treatment of hepatocellular carcinoma (HCC). The most common diagnostic problem in HCC is distinguishing it from a metastatic carcinoma. The literature from India on HCC is scanty. Hence, we studied the cytomorphological features of HCC and metastatic carcinoma. The study included 37 cases of space-occupying lesions (SOLs) of the liver as demonstrated by ultrasound or computed tomography (CT) scan. Cytomorphological features of these SOLs were analyzed in all subsequent to FNAB. Hepatitis B surface antigen (HBsAg), anti-hepatitis C virus antibody (anti-HCV) and alpha-fetoprotein (AFP) were determined in all the cases by enzyme-linked immunosorbent assay (ELISA). The cytopathological diagnosis was HCC in 22 and metastatic carcinoma of the liver in 15. The individual cytomorphological features and which helped to make a definite diagnosis of HCC were: a high nuclear cytoplasmic ratio (81.8%), predominantly trabecular pattern (63.6%) and atypical naked nuclei (100%). Other features were prominent multiple nucleoli (63.3%), hyperchromasia (100%) and moderate anisonucleosis (59%). AFP was elevated in 81.8% of the cases with a mean of 634.8+812.7 ng/ml. HBsAg by ELISA was found to be positive in 72.7% of cases while only 1 case (4.5%) was positive for anti-HCV. In 1 case (4.5%), there was dual infection due to hepatitis B virus (HBV) and HCV. No viral cause was found in 18.3% of cases. PMID:15682657

    2015-01-01

    Background: Malignant pleural effusion is a major clinical problem associated with primary and metastatic pleural malignancies. Pleural effusions from an unknown primary are responsible for 7-15% of all malignant pleural effusions. Presence of malignant pleural effusion puts the patient in advanced stage and renders the prognosis as poor. Aim: In this study we intend to find out the incidence of malignant pleural effusion, its aetiology and clinical course in patients attending a tertiary care teaching hospital. Results: A total of 308 patients were included in this study. A majority of the patients were in age group 50- 70 years (median age = 58.8 years; range 32- 85 yrs). Male to female ratio was 2.5:1. The major primary cancers were lung cancer (135), lymphoma (40), breast cancer (36), female genital tract (30) gastrointestinal (21), and others (8). In 38 cases primary remained unknown. The yields of pleural fluid cytology, blind pleural biopsy, CT/USG guided pleural biopsy and thoracoscopy were 60%, 49%, 76% and 91% respectively. Chemical pleurodesis yielded complete response in 80%, incomplete response in another 13% patients. Only 136 (44%) cases could be followed up for minimum of 6 months. A majority of them (95, 69.85%) died. Conclusion: We conclude that malignant pleural effusion is a commonly misdiagnosed medical entity. Lung cancer is the commonest cause. Despite all efforts, in about 15% of the cases, primary remains undiagnosed. Thoracoscopy/pleuroscopy is a cost effective measure for diagnosis. Chemical pleurodesis provides expected results but mortality remains high. PMID:26180380

    Background: Infections of the central nervous system (CNS) are common and routinely encountered. Our aim was to evaluate the neuroimaging features of the various infections of the CNS so as to differentiate them from tumoral, vascular, and other entities that warrant a different line of therapy. Aims: Our aim was to analyze the biochemical and magnetic resonance imaging (MRI) features in CNS infections. Settings and Design: This was a longitudinal, prospective study over a period of 1½ years. Subjects and Methods: We studied cerebrospinal fluid (CSF) findings and MRI patterns in 27 patients of 0–20 years age group with clinical features of CNS infections. MRI was performed on MAGNETOM Avanto 18 Channel 1.5 Tesla MR machine by Siemens India Ltd. The MRI protocol consisted of diffusion-weighted and apparent diffusion coefficient imaging, turbo spin echo T2-weighted, spin echo T1-weighted, fluid-attenuated inversion recovery (FLAIR), and gradient-echo in axial, FLAIR in coronal, and T2-weighted in sagittal plane. Contrast-enhanced T1-weighted sequence and MR spectroscopy were done whenever indicated. Results and Conclusions: We found that most of the children belong to 1–10 years age group. Fungal infections were uncommon, mean CSF adenosine deaminase values specific for tuberculosis and mean CSF glucose-lowered in pyogenic. Hemorrhagic involvement of thalamus with/without basal ganglia and brainstem involvement may indicate Japanese encephalitis or dengue encephalitis. Diffusion restriction or hemorrhage in not expected in the brainstem afflicted lesions of rabies. Congenital cytomegalovirus can cause cortical malformations. T1 hyperintensities with diffusion restriction may represent viral encephalitis. Lesions of acute disseminated encephalomyelitis (ADEM) may mimic viral encephalitis. Leptomeningeal enhancement is predominant in pyogenic meningitis. Basilar meningitis in the presence of tuberculomas is highly sensitive and specific for tuberculosis. PMID:27195033

    Vascular endothelial growth factor (VEGF) mediates neo-angiogenesis during tumour progression and is known to cooperate with the fibroblast growth factor (FGF) system to facilitate angiogenesis in a synergistic manner. In view of this, we have investigated VEGF expression in 67 cases of prostate cancer previously characterized for fibroblast growth factor-8 (FGF-8) expression. Cytoplasmic VEGF staining was detected in malignant cells in 45 out of 67 cases. Cytoplasmic staining was found in adjacent stromal cells in 32 cases, being particularly strong around nests of invasive tumour. Positive VEGF immunoreactivity in benign glands was restricted to basal epithelium. A significant association was observed between tumour VEGF and FGF-8 expression (P = 0.004). We identified increased VEGF immunoreactivity in both malignant epithelium and adjacent stroma and both were found to be significantly associated with high tumour stage (P = 0.0047 and P = 0.0002, respectively). VEGF expression also correlated with increased serum PSA levels (P = 0.01). Among positively stained tumours, VEGF expression showed a significant association with Gleason score (P = 0.04). Cases showing positive VEGF immunoreactivity in the stroma had a significantly reduced survival rate compared to those with negative staining (P = 0.037). Cases with tumours expressing both FGF-8 in the malignant epithelium and VEGF in the adjacent stroma had a significantly worse survival rate than those with tumours negative for both, or only expressing one of the two growth factors (P = 0.029). Cox multivariate regression analysis of survival demonstrated that stromal VEGF and tumour stage were the most significant independent predictors of survival. In conclusion, we report for the first time a correlation of both tumour and stromal VEGF expression in prostate cancer with clinical parameters as well as its correlation to FGF-8 expression. © 2001 Cancer Research Campaign http://www.bjcancer.com PMID:11506499

    Background: This study was performed to evaluate and compare the clinical and antimicrobial efficacy of subgingival irrigation with tetracycline and povidone-iodine as an adjunct to nonsurgical periodontal therapy. Materials and Methods: Twenty subjects with chronic moderate periodontitis were recruited in this split-mouth study with probing pocket depth of >3 and ≤5 mm and clinical attachment loss of 3-4 mm in relation to 16, 36, and 46. In each subject, three selected periodontal pockets were assigned to receive one out of three irrigants (1) sterile water (control) in 16; (2) tetracycline at 10 mg/ml in 36; (3) 2% povidone-iodine in 46, and these sites were designated as Group A, Group B, and Group C, respectively. Plaque score, gingival score, pocket probing depth, and clinical attachment level were evaluated before treatment and at 1 and 3 months posttreatment. Multiplex polymerase chain reaction was used to detect Porphyromonas gingivalis and Tannerella forsythensis which have been implicated as the major risk factors for periodontal disease. Subgingival plaque collected before treatment and at 1 and 3 months posttreatment. Data were analysed using ANOVA and repeated measure ANOVA. Results were considered significant if P < 0.05. Results: Clinical and microbiological parameters were reduced posttreatment, the reduction being significantly higher in Group B compared to Group C. Conclusion: It can be concluded that chemical and mechanical therapies were of slight benefit in the treatment of chronic moderate periodontitis, and there was an adjunctive effect of significance when scaling and root planing was combined with a single subgingival irrigation with tetracycline or povidone-iodine in lower concentration.

    2012-01-01

    Background and Objectives: The purpose of the present study was to clinically and radiographically assess the soft and hard tissue changes around the immediately loaded single tooth implants bioactivated with platelet-rich plasma (PRP), placed in the mandibular posterior region. Materials and Methods: A total of 11 patients having single tooth edentulous space in the mandibular posterior region were selected. An endosseous implant was placed after clinical and radiographic examination in each selected site using single stage surgical approach. The patients were followed up at 3, 6, 9, and at 12 months of post implant insertion. The patients were subjected to recording of clinical parameters like modified plaque index, modified gingival index, probing depth, and clinical implant mobility scale. Radiographs made at different intervals were subjected to assessment of bone level mesial and distal to each implant using computer assisted image analysis. Results: Scores for clinical parameters were minimal and comparable. The probing depth around the implant was measured during the follow-up period and the changes observed were statistically non-significant. None of the implants were clinically mobile during the follow-up period. Radiographically, the peri-implant bone resorption both on mesial and distal sides was within normal limit after one year of immediate loading. Finally, the overall success rate for the immediately loaded bioactivated implant placed in the mandibular posterior region was recorded as 100%. Interpretation and Conclusion: The use of platelet-rich plasma may lead to improved early bone apposition around the implant; and thus, results in increased rate of osseointegration. Single stage implant procedure with the adjunctive use of PRP enhances the ability of peri-implant healing tissue to create favorable soft and hard tissue relationships. It also gives the added advantage of psychological boost for the patient by getting fixed replacement of tooth within a short time period. PMID:22628970

    A study was made of gastric biopsy specimens withdrawn on repeated endoscopy in 35 patients with chronic gastric ulcers before and 2 weeks after the treatment by autohemotransfusion of hemosorbent-treated blood (AHTB). In 30 patients, the ulcer healed or reduced in size, in 5 patients, the effect was lacking. Morphologic and morphometric studies were carried out on cryostat sections stained by means of PAS and according to Romanovsky-Giemsa. They involved determination of the specific area of the gland and count of free cells of the stroma surrounding the gland followed by an analysis of correlations between effector cells of the immune system. A comprehensive estimation of the accumulation and distribution of the cells infiltrating m. mucosae of the stomach and of their interaction revealed the dependence on the use of AHTB.

    Comparison of clinical and autopsy findings of the cases studied between 1984 and 1988, were made at the Department of Pathology of the Instituto Nacional de la Nutricion Salvador Zubiran in Mexico City. The goal was to determine the accuracy of clinical diagnoses. The total number of cases was 429. A decreasing number of autopsies as a function of time was observed. Thus, in 1985, 34.65% of the deaths was autopsied, whereas in 1988, the number dropped to 21.16%, overall mean of 27.31%. In 229 autopsies (53.8%), 353 findings of clinical significance were found; of these, 86 were in the main diagnoses and 267 in the causes of death. There were 171 overdiagnoses with therapeutic implications, 38 in the main diagnoses and 133 in the causes of death. Overdiagnoses and underdiagnoses were most common in infectious diseases, followed by respiratory and digestive diseases, while endocrinologic and rheumatologic diseases had the highest diagnostic concordance. It was also found that the diagnostic accuracy did not improve with time of hospitalization. A brief analyses of the probable causes of the decrease in the number of autopsies is made. It is concluded that, in spite of the great advances in clinical and technological knowledge, the high frequency of disagreements between clinical and anatomical diagnoses, indicate that autopsy continues playing a key role in the quality control of medical practice. This justifies by itself the performance of necropsies.

    Aim: To evaluate the clinical and metabolic changes following nonsurgical periodontal therapy of type-2 diabetic patients and nondiabetic patients. Materials and Methods: Fifteen nondiabetics and fifteen type-2 diabetics with moderate to severe periodontitis were selected after meeting inclusion and exclusion criteria. Periodontal pocket probing was performed using a Williams graduated periodontal probe and comparisons of the clinical and biochemical parameters like plaque index, gingival index, probing depth, glycated hemoglobin, and lipid profile (total cholesterol, high density lipoprotein, low density lipoprotein, triglycerides and very low density lipoprotein) were done between and within two groups at baseline and 3 month. Results: A correlation was observed between clinical and biochemical parameters between and within two groups at baseline and 3 month. The P value of diabetic group was<0.001 in all clinical parameters (plaque index PI, Gingival index GI, and Probing Pocket Depth PPD) in diabetic and nondiabetic group, showed statistically highly significant difference in GI, PI, PPD, <.01 in Glycated Hemoglobulin (HbAlc1) in test group and<0.05 in control group showed statistically significant difference. The P value of test group was >0.05 in Lipid profile (total cholesterol, low density lipoprotein, high density lipoprotein, serum triglyceride, very low density lipoprotein) that showed no significant difference and in control group<0.05 in total Cholesterol, high density lipoprotein and <0.01 in Low density lipoprotein, Very Low Density Lipoprotein, and Serum Triglyceride, respectively, showed statistically significant in Total cholesterol, Low density lipoprotein, Very Low Density Lipoprotein, and Serum Triglyceride, not significant in high density lipoprotein. The P value >0.05 showed no statistical significance of correlation between the test and control groups. Conclusion: Both groups of patients showed an improvement in clinical and metabolic parameters assessed at 3 months after nonsurgical periodontal therapy. PMID:21731253

    We report a rare case of synchronous clear cell renal cell carcinoma and multilocular cystic renal cell neoplasia of low malignant potential in the same kidney. The tumors were seen incidentally in a 45-year-old man. Pathologic study revealed that the former tumor was nucleolar grade 2, and the multilocular cystic renal cell neoplasia of low malignant potential was nucleolar grade 1. At immunohistochemistry, the clear cells in both tumors were positive for CD10 and CA IX. Interestingly, these uncommon synchronous tumors showed a different KRAS/NRAS mutation analysis that was characterized by KRAS mutation at codon p.G12C in the clear cell renal cell carcinoma, while this mutation was not present in the case of multilocular cystic renal cell neoplasia of low malignant potential. NRAS mutation was not seen in any of the tumors. PMID:26874573

    Background: Heterogeneous groups of oral lesions are likely to develop among denture wearers. The objectives of this study were to determine the exact prevalence of oral lesions among denture wearers attending the clinics of the College of Dentistry, University of Dammam. Materials and Methods: All denture wearers attending the dental clinics in the period between January 2012 and April 2013 were included in this study. Of the total 210 patients, 166 (79%) were males and 44 (21%) were females. Comprehensive oral examination was performed for all patients. Any denture-induced lesion was biopsied. Data collected were analyzed using SPSS program. Results: Oral lesions were found in 20.5% of the cases under study (43 out of the total 210 denture wearers). Denture-induced fibrous hyperplasia was the most common type of lesion detected (41.9%). A significant correlation (P = 0.004) was found between the type of denture and oral lesions in this study. Conclusion: The prevalence of denture-induced oral lesions was found to differ significantly from that reported in other studies. The diversity of these lesions among different studies depends on the quality and materials of dentures delivered, the techniques used, and the methods of patients’ instructions adopted.

    A fully automated and three-dimensional (3D) segmentation method for the identification of the pulmonary parenchyma in thorax X-ray computed tomography (CT) datasets is proposed. It is meant to be used as pre-processing step in the computer-assisted detection (CAD) system for malignant lung nodule detection that is being developed by the Medical Applications in a Grid Infrastructure Connection (MAGIC-5) Project. In this new approach the segmentation of the external airways (trachea and bronchi), is obtained by 3D region growing with wavefront simulation and suitable stop conditions, thus allowing an accurate handling of the hilar region, notoriously difficult to be segmented. Particular attention was also devoted to checking and solving the problem of the apparent 'fusion' between the lungs, caused by partial-volume effects, while 3D morphology operations ensure the accurate inclusion of all the nodules (internal, pleural, and vascular) in the segmented volume. The new algorithm was initially developed and tested on a dataset of 130 CT scans from the Italung-CT trial, and was then applied to the ANODE09-competition images (55 scans) and to the LIDC database (84 scans), giving very satisfactory results. In particular, the lung contour was adequately located in 96% of the CT scans, with incorrect segmentation of the external airways in the remaining cases. Segmentation metrics were calculated that quantitatively express the consistency between automatic and manual segmentations: the mean overlap degree of the segmentation masks is 0.96 ± 0.02, and the mean and the maximum distance between the mask borders (averaged on the whole dataset) are 0.74 ± 0.05 and 4.5 ± 1.5, respectively, which confirms that the automatic segmentations quite correctly reproduce the borders traced by the radiologist. Moreover, no tissue containing internal and pleural nodules was removed in the segmentation process, so that this method proved to be fit for the use in the

    The multivariant approach offers best possibilities for assessment of liver function. The role of the different clinical, clinico-laboratory and combined clinical and clinicochemical indices in the prognosis of liver cirrhosis was studied in patient in ambulatory conditions. A step regressive mathematical model with the help of the program 2R of the statistical package BMDP was used. The regression of the clinical indices by 5 steps of the mathematical model showed that of greatest importance for the survival are the following indices: ascites, months since its onset, collaterals, anorexia and vascular nevi. By 4 steps of the regressive model of the clinico-chemical indices the following indices were chosen: prothrombin time, albumin, total bilirubin, cholesterol and alkaline phosphatase. The regression of the combined clinical and clinico-chemical indices pointed out as basic factors 3 clinical indices (ascites, months since its onset, collaterals) and 3 clinico-chemical indices related to the disturbed liver function (prothrombin time, total bilirubin, albumin).

    Background. Gli ambienti di apprendimento clinico sono definiti come una rete di fattori interagenti nel contesto, in grado di influenzare gli esiti dell’apprendimento degli studenti. La soddisfazione degli studenti è considerata un indicatore del raggiungimento degli esiti dell’apprendimento ed è determinante a partire dalla prima esperienza di tirocinio. Scopo. Analizzare l’esperienza di apprendimento clinico degli studenti infermieri del primo anno di corso dopo il primo tirocinio clinico ed identificare i principali determinanti della soddisfazione degli studenti. Metodo. Lo studio osservazionale è stato realizzato in cinque sedi universitarie italiane del Corso di Laurea in Infermieristica. 420 studenti hanno compilato la versione italiana della “Clinical Learning Environment, Supervision and plus Nurse Teacher (CLES+T) scale” al termine del primo tirocinio clinico. Risultati. I punteggi medi assegnati alle dimensioni della scala variano da 4.02 (clima di apprendimento) a 3.30 (relazione di tutorato). La maggior parte degli studenti è soddisfatto della propria esperienza di tirocinio (75.6%), ma sono emerse differenze in relazione alle diverse sedi di tirocinio clinico. Discussione. I principali determinanti della soddisfazione sono lo stile di leadership del coordinatore infermieristico e l’integrazione teoria-pratica nella relazione fra tutor clinico, universitario e studente. Conclusioni. I risultati dello studio contribuiscono alla comprensione della prima esperienza di tirocinio degli studenti. Tuttavia, sono necessarie ulteriori ricerche per determinare le variabili organizzative specifiche e i modelli tutoriali in grado di aumentare la soddisfazione degli studenti, per sviluppare strategie formative basate sull’integrazione tra tutor universitari e guide di tirocinio.

    Introduzione: Per divenire dei professionisti qualificati, gli studenti infermieri sperimentano diverse esperienze di tirocinio clinico. L’opinione dello studente può essere considerata un indicatore della qualità dell’insegnamento e una percezione positiva dell’esperienza di tirocinio si correla strettamente ad un apprendimento efficace. La scala CLES+T (Clinical Learning Environment and Supervision plus Nurse Teacher) è lo strumento psicometrico “gold standard” per valutare la qualità dell’ambiente di apprendimento clinico. Scopo: Valutare la qualità dell’ambiente di apprendimento clinico mediante la scala (CLES+T) ed evidenziare significative correlazioni inerenti le caratteristiche degli studenti, del modello tutoriale e dell’ambiente clinico. Metodo: Il 4 marzo 2013, durante una convocazione plenaria, è stata somministrata la scala CLES+T ai 242 studenti del 2° e 3° anno del Corso di Laurea in Infermieristica di Modena (Università di Modena e Reggio Emilia). Tutti i risultati sono stati statisticamente analizzati (Test della mediana). Risultati: Tutti i valori mediani si sono attestati ad un livello “4” (scala di Likert). La valutazione ottenuta dallo studente al termine del tirocinio clinico è l’unica variabile statisticamente correlata ai punteggi della scala, più il voto è basso peggiore risulta la valutazione dell’esperienza di tirocinio. In base all’opinione degli studenti le aree cliniche pediatriche e critiche hanno valutazioni più elevate. Conclusioni: Le valutazioni degli studenti erano uniformemente positive ed erano correlate al voto finale di tirocinio. Un clima di apprendimento positivo è stato considerato molto importante in questo studio. Questi risultati suggeriscono che un ambiente di apprendimento clinico favorevole e non ostile può influenzare gli esiti dell’apprendimento degli studenti. Concludiamo affermando che la scala CLES+T può essere uno strumento utile per esplorare il clima in tutte le

Aunque de manera general se habla de un diagnostico estable, se ha evidenciado la necesidad de profundizar mas en los factores que influyen en dicha estabilidad. Pacientes y metodos. Los participantes de la muestra fueron 142 menores con TEA (118 varones y 24 mujeres), con una mediana de 33 meses y un recorrido intercuartilico de 12 en la primera evaluacion, y con una mediana de 47 meses y un recorrido intercuartilico de 29 en el seguimiento. Los diagnosticos se realizaron con las siguientes pruebas: escala Merrill-Palmer revisada, escala de Leiter revisada, escala de inteligencia de Wechsler para preescolar y primaria III y escala de inteligencia de Wechsler para niños revisada y IV; ademas de la escala Vineland y la escala de observacion diagnostica del autismo generica (ADOS-G), basandose el diagnostico clinico en los criterios diagnosticos del Manual diagnostico y estadistico de los trastornos mentales, cuarta edicion, texto revisado (DSM-IV-TR), y quinta edicion (DSM-5). Para la evaluacion de la estabilidad diagnostica, se realizaron tablas de contingencia para las valoraciones del diagnostico en funcion del juicio clinico y los resultados de la ADOS-G. Resultados. El diagnostico clinico basado en los criterios del DSM-IV-TR, el DSM-5 y el juicio clinico se mantiene estable a traves del tiempo en un 96% de los casos. Si se valora la estabilidad diagnostica teniendo en cuenta los resultados del ADOS-G (n = 30), el 87% de los casos mantiene el diagnostico. El ANOVA muestra diferencias estadisticamente significativas para las medidas del factor intrasujeto del cociente intelectual y la edad social global, pero no para el diagnostico. Conclusiones.

    2008-01-01

    Objective: This article is a systematic review of various changes in the evolution of the contemporary clinico-pathological staging of transitional cell carcinoma (TCC). Materials and Methods: A thorough search of the literature was done by Medline and other internet references. Results: Accurate staging of TCC is necessary for designing optimal therapy in clinical practice. Further, the current emphasis on bladder conservation and improved long-term disease free survival (DFS) necessitates minimal errors in staging and it's predictability towards recurrence and progression. Traditionally, the staging of TCC revolves around clinical and pathological findings. The staging has evolved through the understanding of various clinico- pathological factors like tumor appearance, number, size, grade, depth of invasion, muscle substratification, lymphovascular invasion and has reached the standard TNM classification. Cystoscopy and transurethral resection still remain the mainstay of staging and noninvasive imaging techniques have further enhanced the accuracy. Conclusion: The TNM classification for bladder cancer is currently the gold standard for TCC. PMID:19468363

    The Italian physician Giovanni Battista Morgagni was the founder of the clinico-anatomical method. His masterpiece De sedibus, et causis morborum per anatomen indagatis represented a major breakthrough in the history of medicine. In the murals of Diego Rivera at the National Institute of Cardiology, Morgagni appears at the center of the fresco. With his left index finger points to the chest of a dying patient with a bulging pulsating aortic aneurysm below the left clavicle, and with his right hand, that holds a scalpel, shows the aneurysm found at the autopsy table. With this striking image the clinico-anatomical method is succinctly depicted. Professor Ignacio Chávez, the founder of the National Institute of Cardiology, gave the artist the elements to draw Morgagni, but the disposition and the importance of Morgagni in the fresco were due to the talent of Rivera.

    INTRODUCTION Mucinous cystic neoplasms (MCN) are uncommon tumors of the pancreatic corpus/tail occurring mostly in middle-aged women, with a variable clinico-biological behavior. On histology, MCNs concurrently show an epithelial mucosecreting component with ovarian-type stromal cells. PRESENTATION OF CASE This report describes the first case of a pancreatic MCN with no ovarian-type stroma in a patient with Turner syndrome (TS). DISCUSSION The mesenchymal component of MCN presumably results from the intra-pancreatic entrapment of ovarian stroma during embryogenesis. In our case, the absence of such stromal component may relate to the “dysgenetic” changes in the ovary involved in TS. CONCLUSION The present case of primary pancreatic MCN arising in a TS-patient triggers some original speculation on the morphogenesis of pancreatic MCN, also expanding the current clinico-pathological knowledge of this extremely rare entity.

    Breast calcifications are among the most common abnormal radiographic findings detected at screening mammography. This essay illustrates the clinico-pathological features of nine screen-detected breast carcinomas, which had benign-appearing macrocalcifications, as a radiographically dominant presenting feature. We aimed to demonstrate that benign-appearing calcifications within a breast lesion are not diagnostic of a benign process if the other imaging characteristics of the lesion are suspicious of malignancy.

    Solitary fibrous tumor is an uncommon neoplasm affecting adults and typically located in the pleura and can also occur in a large number of other extra thoracic sites. We present the case of a solitary fibrous tumor (SFT) of the retroperitoneum and describe their histopathological and immunohistochemical features. The identification of SFT in the retroperitoneum is of importance because its clinico-pathological behaviour is still unclear. The pathologist plays a fundamental role in establishing both the positive and differential diagnosis.

    Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological condition, generally observed in conjunction with severe and acute hypertension, that involves mainly the posterior head areas (occipital and temporal lobes) and anterior "watershed" areas. In this syndrome it is rare to observe a predominant involvement of the brainstem. We describe the clinical and radiological findings in a patient with brainstem involvement, discussing its pathophysiological features and possible differential diagnosis.

    1998-03-01

    A 9-year-old male German shepherd dog was evaluated for clinical and clinico-pathological changes that were suggestive of Addison's disease. On further investigation the basal plasma cortisol concentration was high, a normal cortisol response to ACTH stimulation occurred, plasma renin activity was elevated and low serum aldosterone concentration was present. A diagnosis of hyperreninaemic hypoaldosteronism was made. Replacement fludrocortisone resulted in complete normalisation of the electrolyte and fluid imbalances. Hyperreninaemic hypoaldosteronism has never been reported in the dog.

    Ossifying fibroma is a benign fibro-osseous lesion which occurs at various locations in maxillofacial region. A synchronous presentation of this lesion in both, the maxilla and the mandible is a rare occurrence. The present article reports a case of ossifying fibroma in a 45-year-old woman who manifested lesions in the right maxilla and mandible. The clinico-radiologic and histopathologic modalities of diagnosing this entity are evaluated and discussed. PMID:25838685

  19. Establishment and identification of a rabbit model of peritoneal carcinomatosis from gastric cancer

    PubMed Central

    2010-01-01

    Background Gastric cancer peritoneal carcinomatosis is a common clinical problem, but there are no suitable large animal models to study this problem. This study was to establish a stable rabbit peritoneal carcinomatosis model of gastric cancer using VX2 tumor, and analyze the clinico-pathological features. Methods VX2 tumor was implanted into 36 New Zealand rabbits by 3 methods: laparotomic orthotopic injection of cancer cells into the submucosal layer of the stomach (Group A), laparotomic implantation of tumor tissue into the greater omentum immediately beneath the gastric antrum (Group B), and percutaneous injection of tumor cells directly into the peritoneal cavity (Group C), 12 rabbits in each group. The animals were closely observed and detailed clinico-pathological studies were conducted. Results The success rates of peritoneal carcinomatosis formation were 100% (12/12), 91.7% (11/12) and 58.3% (7/12), respectively, for Groups A, B and C (P = 0.019, A versus C; P = 0.077, B versus C; P = 0.500, A versus B, Fisher's exact test). Two weeks after submucosal cancer cells injection in Group A, ulcerative gastric cancer with peritoneal carcinomatosis showed typical VX2 tumor pathology, with widespread intraperitoneal metastatic nodules, bloody ascites and perspicuous pulmonary metastases. The clinico-pathological progression pattern was very similar to patients of advanced gastric cancer with peritoneal carcinomatosis. Groups B and C showed similar pattern of cancer progression, but less aggressive. Conclusions First large animal model of peritoneal carcinomatosis from gastric cancer has been established by laparotomic orthotopic injection of VX2 cancer cells into the submucosal layer of the stomach, providing a more suitable model for surgical interventional studies. The clinico-pathological features of this model resemble human peritoneal carcinomatosis. PMID:20359350

    MRI in a 63-year-old male with isolated lateropulsion of the trunk disclosed an infarct in the inferior portion of the right cerebellar hemisphere, suggesting an end-zone type infarct in the lateral branch of the right posterior inferior cerebellar artery (1PICA) or a borderzone infarct between 1PICA and superior cerebellar artery. A close clinico-topographical relationship between isolated lateropulsion of the trunk and lesion in the territory of 1PICA was demonstrated.

    118 adult patients with respiratory, cardiovascular, digestive, urino-genital or endocrinological diseases have been observed. Kirlian diagnostics on palm finger radiation has been used along with common clinico-laboratory methods. Data comparison of these methods showed that Kirlian diagnostics can be used in clinical differential diagnostics as an supplementary method to determine the severity of the pathological process, its pathogenesis, functional state of compensatory reactions. It helps to determine preclinical and residual signs of a disease. PMID:15605819

    Subacute osteomyelitis (Brodie's abscess) is essentially a problem of diagnosis, and there may be considerable difficulty in distinguishing it from other benign and malignant bone lesions. Though reported in the metaphyseal region of the femur, Brodie's abscess is rarer in the femoral neck. The authors present a case of Brodie's abscess in the femoral neck, which clinico-radiologically simulated an osteoid osteoma. Retrospectively, the presence of a cortical sinus tract should have aroused suspicion.

El paciente moviliza el miembro sano frente a un espejo, de modo que mira el reflejo del movimiento del lado sano como si fuera el lado afectado. Objetivo. Analizar el efecto de la terapia de espejo en el paciente hemiplejico en cuanto a funcion sensitivomotora, heminegligencia y actividades de la vida diaria. Desarrollo. Se definio una estrategia de busqueda bibliografica en Medline, EMBASE, PEDro y Cochrane Central Register of Controlled Trials de ensayos clinicos aleatorizados llevados a cabo con pacientes hemiplejicos en los que se utilizara como intervencion rehabilitadora principal la terapia de espejo. Siete estudios cumplieron los criterios de inclusion con nivel medio-alto de calidad metodologica. La mayoria de los estudios valora el efecto de la terapia de espejo sobre el deficit motor, con mejorias significativas. Se encontraron tres ensayos clinicos aleatorizados que evaluan el efecto de la terapia de espejo sobre la heminegligencia, con beneficios tambien significativos. Conclusiones. La terapia de espejo combinada con una rehabilitacion convencional es efectiva sobre todo en la funcion motora y no tanto en la funcion sensitiva y en la funcionalidad global del paciente hemiplejico. En la heminegligencia se obtienen resultados tambien beneficiosos, aunque se basan en pocos ensayos clinicos aleatorizados y con muestras de pacientes reducidas, por lo que los resultados, aunque prometedores, son poco concluyentes.

    Introduccion. El sindrome de Gorlin (SG) es un trastorno de herencia autosomica dominante asociado a mutaciones en el gen PTCH1, cuya principal caracteristica es la aparicion de carcinomas basocelulares, unido a anomalias esqueleticas, queratoquistes odontogenicos y tumores intracraneales. Caso clinico. Niña de 3 años y 10 meses, ingresada por ataxia aguda. Destacan como antecedentes personales retraso psicomotor y como antecedentes familiares la sospecha de SG en la madre por quiste maxilar. En la exploracion, se aprecia macrocefalia con frente prominente e hipertelorismo, asi como nevo. Se solicita estudio genetico de SG, en el que se detecta la mutacion c.930delC en el exon 6 del gen PTCH1 en heterocigosis. Conclusiones. En el SG hay un aumento de la susceptibilidad al desarrollo de carcinomas basocelulares y es preciso un estrecho control dermatologico. Es necesario un seguimiento neurologico clinico y de imagen, mediante resonancia magnetica, para el diagnostico precoz de tumores intracraneales, fundamentalmente el meduloblastoma. Tambien son caracteristicos los queratoquistes odontogenicos, otras alteraciones cutaneas, fibromas cardiacos y ovaricos, asi como anomalias esqueleticas, que precisan controles clinicos y de imagen periodicos, y tratamiento en caso de ser necesarios, pero debe evitarse la radiacion. El SG es un trastorno poco frecuente, que se debe sospechar ante la presencia de alteraciones caracteristicas. Es necesario un seguimiento multidisciplinar, asi como establecer un protocolo de actuacion, para un temprano diagnostico y tratamiento de las complicaciones potencialmente graves derivadas de esta enfermedad.

    Introduccion. La paraplejia espastica hereditaria (PEH) representa un conjunto de cuadros clinicos neurodegenerativos que se caracteriza por perdida progresiva de fuerza en los miembros inferiores con espasticidad. Esto se debe a una lesion axonal en los haces corticoespinales. La de tipo 1, conocida como SPG1, es la forma mas comun de PEH ligada al cromosoma X. Esta se produce por una mutacion en el gen de la molecula de adhesion celular L1 (L1CAM). La SPG1 se manifiesta con el sindrome CRASH (corpus callosum hypoplasia, retardation, adducted thumbs, spasticity and hydrocephalus). Casos clinicos. Tres varones, dos hermanos y un primo (materno), con un cuadro clinico de discapacidad intelectual, paraparesia espastica, piramidalismo, dismorfias faciales y pulgares en aduccion. La neuroimagen mostro agenesia del cuerpo calloso y ventriculomegalia en los tres. Los estudios neurofisiologico y metabolico fueron normales. El estudio genetico evidencio en todos ellos una mutacion concreta en el gen L1CAM (Xq28). Conclusion. Se describen los hallazgos clinicorradiologicos de tres varones afectos de sindrome CRASH por mutacion c.516G>A en el exon 5 del gen L1CAM. Estos parecen ser los primeros casos descritos en España segun la bibliografia actual. Recomendamos sospechar este sindrome cuando se asocian paraparesia espastica, discapacidad intelectual y pulgares aductos.

    Introduccion. El mieloma multiple es la neoplasia de celulas plasmaticas mas frecuente. Al ser incurable, el tratamiento persigue obtener el mayor tiempo de supervivencia libre de clinica. Constituye una causa extremadamente rara de afectacion de los nervios craneales y es producido habitualmente por un plasmocitoma intracraneal. Presentamos un caso de mieloma multiple, que asociaba un plasmocitoma intracraneal y que comenzo clinicamente con paralisis aislada, completa y fluctuante del III nervio craneal. Caso clinico. Mujer de 63 años que acudio a urgencias por presentar un cuadro clinico oscilante, consistente en diplopia binocular horizontal y, posteriormente, cefalea. La exploracion neurooftalmologica revelo una paralisis completa del III nervio craneal derecho. Se solicito una tomografia axial computarizada craneal urgente, que revelo multiples lesiones osteoliticas diploicas, asociando una de ellas componente de partes blandas en la hendidura esfenoidal derecha. La paciente fue ingresada, y se le diagnostico posteriormente un mieloma multiple IgA-kappa. Tras recibir induccion quimioterapica y ser sometida a un trasplante autologo de progenitores hematopoyeticos, alcanzo la remision completa. Conclusiones. El mieloma multiple es un trastorno raro de los nervios craneales, una causa muy infrecuente de paralisis aislada y completa del III nervio craneal y menos aun fluctuante, y no se ha encontrado ningun caso publicado con este inicio clinico. Tener en cuenta las posibles manifestaciones neurooftalmologicas del mieloma multiple puede contribuir a un diagnostico precoz y a una incidencia positiva sobre el curso de esta enfermedad.

    Introduccion. El sindrome de encefalopatia posterior reversible (SEPR) es un sindrome clinico-radiologico de presentacion aguda o subaguda que se caracteriza por la presencia de cefalea, vomitos, crisis epilepticas, trastornos visuales y alteracion del nivel de conciencia asociado a lesiones localizadas fundamentalmente en la sustancia blanca de regiones posteriores cerebrales. Caso clinico. Mujer de 32 años que desarrollo un SEPR en el periodo posparto secundario a eclampsia tardia. La paciente presento 10 dias despues del parto un cuadro clinico consistente en cefalea, crisis epilepticas, ceguera y deterioro del nivel de conciencia. El estudio de imagen con resonancia magnetica confirmo la afectacion de la sustancia blanca de predominio posterior. Conclusiones. Aunque la eclampsia es una entidad tipica del embarazo y puerperio inmediato, es necesario recordar que tambien puede producirse de forma tardia tras el parto y que puede ser la causa de otros sindromes, como el SEPR. Aunque en estos casos el pronostico suele ser favorable, el tratamiento debe ser precoz, efectuando un rapido control de la tension arterial y las convulsiones con el fin de evitar un daño cerebral permanente. Es necesario considerar siempre este sindrome en mujeres con crisis epilepticas u otros sintomas neurologicos durante el posparto.

Esta poblacion presenta dos rasgos clinicos caracteristicos: la presencia de demencia con semiologia distinta a la enfermedad de Alzheimer tipica y deficits intelectuales previos que pueden confundir el diagnostico clinico. Existe una evidente necesidad de validar instrumentos especificos en castellano adaptados a esta poblacion. Objetivo. Adaptar y validar el Cambridge Examination for Mental Disorders of Older People with Down's Syndrome and Others with Intellectual Disabilities (CAMDEX-DS) en poblacion española. Pacientes y metodos. Se consideraron 146 pacientes con discapacidad intelectual (leve-moderada). Se realizo un estudio de validacion de tipo observacional, transversal y multicentrico. Se administraron los siguientes tests: CAMDEX-DS, test breve de inteligencia de Kaufman y Dementia Questionnaire for Persons with Mental Retardation. Se calculo la fiabilidad test-retest, la fiabilidad interjueces, la concordancia del CAMDEX-DS para el diagnostico clinico y la validez. Resultados. La fiabilidad test-retest e interjueces obtuvo un coeficiente kappa de 0,92 y 0,91, respectivamente. El indice kappa del CAMDEX-DS para el diagnostico clinico respecto al resto de los criterios clinicos utilizados fue alto: CAMDEX-DS frente a DSM-IV (kappa = 0,95; p < 0,001); CAMDEX-DS frente a Clasificacion Internacional de Enfermedades, decima revision (kappa = 0,97; p = 0,000). Todas las correlaciones item-test oscilaban entre 0,31 y 0,69. La fiabilidad interna calculada mediante el alfa de Cronbach fue de 0,93. Conclusiones. La version española del CAMDEX-DS es un instrumento valido, de alta aplicabilidad a personas con discapacidad intelectual, que muestra buenas propiedades psicometricas. El Cambridge Cognitive Examination for Older Adults with Down's Syndrome (CAMCOG-DS) permite establecer dos puntos de corte para la sospecha de deterioro

    Introduccion. El mosaicismo diploide/triploide es una alteracion cromosomica poco frecuente. La produce un fallo en la division poscigotica durante el desarrollo embrionario. Da lugar a la coexistencia de dos lineas celulares con diferente constitucion cromosomica (46,XX y 69,XXX) en un mismo individuo. Su fenotipo clinico es caracteristico. Las alteraciones pigmentarias con un patron de distribucion que sigue las lineas de Blaschko son el principal signo guia, asi como las alteraciones de otros tejidos derivados del ectodermo. Casos clinicos. Describimos las caracteristicas clinicas de tres pacientes afectos de mosaicismo diploide/triploide y realizamos una comparacion de su fenotipo clinico con el de los casos publicados previamente en la bibliografia. Las alteraciones observadas con mayor frecuencia fueron alteraciones cutaneas, discapacidad intelectual, obesidad troncular, talla baja, hemihipertrofia, y manos pequeñas y estrechas con clino y camptodactilia. Las caracteristicas fenotipicas de nuestros pacientes fueron similares a las de los casos comunicados previamente. Aunque no existe un fenotipo unico y especifico asociado al mosaicismo diploide/triploide, existen malformaciones caracteristicas que conforman un sindrome malformativo bien definido. El cariotipo realizado en linfocitos de sangre periferica en las tres pacientes fue normal, y se logro el diagnostico mediante cariotipo en fibroblastos cultivados tras biopsia de piel hipopigmentada. Conclusiones. La presencia de discapacidad intelectual asociada a obesidad troncular, talla baja, hemihipertrofia o clino y camptodactilia, ademas de las alteraciones cutaneas, debe hacer pensar en la posible existencia de un mosaicismo diploide/triploide. En la mayoria de los casos, es necesario el estudio del cariotipo en los fibroblastos para llegar al diagnostico.

    Introduccion. La epilepsia es una patologia cerebral que afecta tanto a niños como a adultos. Desde los años veinte, la dieta cetogenica ha ganado prestigio como otra opcion de tratamiento en pacientes con epilepsia refractaria. Sujetos y metodos. Se realiza una sintesis de la evidencia a traves de una revision sistematica de ensayos clinicos aleatorizados que hayan comparado una dieta cetogenica sola con otros tipos de dieta para el tratamiento de estos pacientes. Objetivo. Determinar la efectividad de la dieta cetogenica en la disminucion de los episodios de convulsiones en pacientes con epilepsia refractaria. La estrategia de busqueda incluyo ensayos clinicos aleatorizados y ensayos clinicos controlados. Las bases de datos usadas fueron: Medline, LILACS, Central y CINAHL. Resultados. Se obtuvieron seis articulos que cumplian con los criterios de elegibilidad. Conclusiones. Existe evidencia limitada de que la dieta cetogenica en comparacion con la dieta de trigliceridos de cadena media es mas efectiva en disminuir la frecuencia de las convulsiones. Existe evidencia moderada de que la dieta cetogenica clasica en comparacion con la dieta gradual (2,5:1 y 3:1) es mas efectiva para disminuir las crisis epilepticas. Existe evidencia moderada de que la dieta cetogenica clasica en comparacion con la dieta Atkins es mas efectiva para disminuir la frecuencia de convulsiones en tres meses. La decision de aplicar este tipo de dietas tambien debe basarse en costes, preferencias y seguridad del tratamiento. Ademas, debe considerarse la probabilidad de que algunos estudios, por problemas de indizacion, hayan quedado fuera de la revision.

    Introduccion. La enfermedad de Alzheimer (EA) es la causa mas frecuente de demencia en nuestro medio. En la mayoria de los pacientes, las manifestaciones iniciales consisten en una afectacion selectiva y progresiva de la memoria. Sin embargo, no se trata de un proceso homogeneo y, en algunos casos, el modo de presentacion puede ser atipico. La presentacion de la EA en forma de alteracion precoz de la personalidad, el comportamiento y las funciones ejecutivas se ha denominado variante frontal de la EA. En nuestro caso, su diagnostico definitivo solo fue posible mediante el estudio histologico, pues los criterios clinicos vigentes resultaron entonces insuficientes para el diagnostico de esta forma atipica de la EA. Casos clinicos. Dos pacientes, una mujer y un hombre de 60 y 52 años respectivamente, presentaron un cuadro progresivo de deterioro cognitivo con afectacion inicial de las funciones ejecutivas y cambio de personalidad, junto con alteraciones del estado de animo, por lo que se realizo el diagnostico inicial de probable demencia frontotemporal. No obstante, en ambos casos, la autopsia revelo datos compatibles con el diagnostico de EA, con una distribucion de la patologia que afectaba fundamentalmente a los lobulos frontales. Conclusiones. La EA tiene una forma heterogenea de presentacion, lo que puede originar errores en su diagnostico inicial, dado que los criterios clinicos actuales no recogen de modo suficiente esta variabilidad clinica. Por ello, consideramos importante prestar atencion a las formas atipicas de la EA con el objeto de desarrollar nuevos metodos diagnosticos que permitan diferenciar la EA del resto de procesos degenerativos.

    Introduccion. El sindrome de Aicardi-Goutieres es una rara encefalopatia subaguda progresiva de inicio precoz –generalmente en el primer año de vida– caracterizada por retraso psicomotor, microcefalia, alteraciones en la sustancia blanca cerebral, calcificaciones intracraneales, pleocitosis y niveles elevados de interferon alfa en el liquido cefalorraquideo. Asocia un incremento en la expresion de los genes estimulados por interferon en la sangre periferica, hecho conocido como interferon signature. Los niveles de genes estimulados por interferon se han postulado como un buen biomarcador, pues se mantienen elevados en la sangre periferica en el tiempo y son mas sensibles, en comparacion con las determinaciones de interferon alfa y neopterinas en el liquido cefalorraquideo, las cuales descienden a partir del año de vida. Hasta la fecha se han descrito mutaciones en siete genes que sobreestimulan la via del interferon alfa, y el ultimo en descubrirse ha sido el IFIH1 (interferon induced with helicase C domain 1), con un patron de herencia autosomico dominante. Caso clinico. Se presenta el primer caso descrito en la bibliografia hispana debido a mutacion de novo en el gen IFIH1. Se expone el cuadro clinico, los estudios realizados y la revision de los aspectos clinicos, neurorradiologicos y geneticos. Conclusiones. La herencia de las mutaciones descritas para el sindrome de Aicardi-Goutieres era clasicamente autosomica recesiva, pero estos hallazgos muestran que mutaciones autosomicas dominantes en el gen IFIH1 pueden causar la enfermedad. Como hallazgo de neuroimagen no descrito previamente, presenta una lesion de encefalomalacia quistica en la protuberancia.

    The ambiguity of facts on connection between glucocorticoid receptor gene (GR) Bcl1 polymorphism in rheumatoid arthritis (RA) and its activity as well as lack of facts on its association with serological variants of the desease, makes ir reasonable to investigate its connections between cyclic citrullinated peptide antibodiss (ACCP) concentration and clinico-laboratorial parameters of RA (DAS 28 desease activity score, C-reactive protein concentration (CRP) and erythrocyte sedimentation rate (ESR) level based on GR gene Bcl1 polymorphism. Study involved 161 RA patients aged over 40 as well as 96 healthy individuals. Routine examination of RA diagnostics, anthropometric and molecular genetic methods were used in the research. Statistical analysis of the results was performed using SPSS-17 program. It has been proved that there is no significant difference in GR gene Bcl1 polymorphism distribution based on DAS 28 RA desease activity score, ACCP concentration and ESR level. However, we have found out that G/G genotype bearers have positive correlation relationship between ACCP titre and RA activity by laboratorial parameters (CRP, ESR),DAS 28 score and rheumatoid factor (RF) which has not been found in C/C and C/G genotype bearing patients. The above indicates the association of G/G genotype by GR gene Bcl1 polymorphism with clinico-laboratorial parameters of RA inflammatory activity. In course of the study we have identified the existance of correlation relationship between ACCP concentration and DAS 28 score of RA activity, CRP concentration and ESR level in individuals bearing G/G gene by GR gene Bcl11 polymorphism gene. The association between GR gene Bcl1 polymorphism and clinico-laboratorial parameters of RA inflammatory activity has not been found. PMID:26483373

Objetivo. Estudiar las caracteristicas electroclinicas sugestivas de una evolucion atipica en la epilepsia rolandica. Pacientes y metodos. Se realizo una busqueda retrospectiva de 133 niños diagnosticados de epilepsia focal benigna atipica (EFBA), sindrome de Landau-Kleffner y epilepsia de punta-onda continua durante el sueño (POCS). Se seleccionaron nueve pacientes que, en el trascurso de su epilepsia rolandica, presentaron un cuadro clinico atipico y un patron electroencefalografico (EEG) de estado epileptico electrico durante el sueño (ESES). Resultados. El inicio de la epilepsia rolandica fue, en promedio, a los 5 años. Los pacientes presentaron un empeoramiento clinico y del EEG año y medio mas tarde en promedio. En tres pacientes se observaron caracteristicas de EFBA, y en seis, de POCS. No se encontraron casos de sindrome de Landau-Kleffner. El EEG en vigilia mostro una focalidad centrotemporal izquierda en seis pacientes, y derecha, en tres. Todos los pacientes presentaron un ESES en el EEG de sueño. En tres de ellos se observo un patron atipico de ESES regional. Ademas, se detectaron alteraciones cognitivas y conductuales por deficits en areas especificas del aprendizaje, como lenguaje, memoria, atencion e inquietud. Conclusiones. El inicio precoz de la epilepsia rolandica, la aparicion de nuevas crisis con un incremento en su frecuencia y una focalidad frontocentrotemporal en el EEG, que aumenta en frecuencia, tanto en vigilia como en sueño, son caracteristicas electroclinicas sugerentes de una evolucion atipica.

    Introduccion. La Children's Communication Checklist (CCC) de Bishop es una prueba util para la valoracion de la pragmatica verbal en los escolares. El objetivo del trabajo es comprobar la fiabilidad y la validez de esta escala en castellano. Sujetos y metodos. Se analiza la CCC contestada por los padres de 360 niños/as de 4-12 años, con inteligencia normal, 160 controles y 200 de cuatro grupos clinicos: trastorno por deficit de atencion/hiperactividad (n = 68), trastorno de aprendizaje no verbal procedimental (n = 77), trastorno de la comunicacion social (n = 25) y trastornos del espectro autista de nivel 1 (n = 30). Se realizan analisis: factorial para agrupar los items del cuestionario, de fiabilidad de las nuevas escalas y discriminante para comprobar si clasifica bien a los afectos de dificultades en el uso del lenguaje. Resultados. Se obtienen siete factores (Kaiser-Meyer-Olkin: 0,852) con moderada similitud a las de la CCC original: relaciones sociales, intereses y otros cinco que constituyen pragmatica (habilidades conversacionales, coherencia-comprension, compenetracion, comunicacion no verbal y pertinencia). La correlacion es significativa entre todos ellos, en el grupo control, y entre los cinco que configuran pragmatica, en los grupos clinicos (r de Pearson). La fiabilidad de las escalas es buena (alfa de Cronbach: 0,914). El cuestionario clasifica bien al 98,9% de los casos agrupados con y sin trastorno pragmatico; y al 78% de los participantes en sus correspondientes grupos clinicos. Ademas, permite diferenciar las patologias segun la presencia e intensidad de los sintomas. Conclusiones. Esta version española de la CCC es altamente valida y fiable. Los estadisticos aportados pueden utilizarse como valores de referencia.

    Introduccion. Las patologias relacionadas con la infiltracion de linfocitos y celulas inflamatorias se clasifican, segun su topografia, en patologia orbitaria idiopatica, paquimeningitis hipertrofica idiopatica, sindrome de Tolosa-Hunt e hipofisitis linfocitaria. Presentamos a una paciente que comenzo con una hipofisitis linfocitaria hace ocho años y ha presentado varios episodios de paquimeningitis hipertrofica variables en su localizacion. Caso clinico. Mujer de 55 años, en seguimiento por cefalea de dos meses de evolucion, que ingreso por empeoramiento clinico con paralisis del III par derecho completo, lagrimeo y rinorrea. Se realizo una resonancia magnetica cerebral que demostro la presencia de una lesion sellar compatible con hipofisitis linfocitaria. Se inicio tratamiento con corticoides con mejoria inicial, pero, tras dos años, la paciente presento empeoramiento clinico con cefalea y parestesias perioculares derechas. Se repitio la resonancia, donde se observaron varias lesiones extraaxiales, siendo el resto de estudios normales, por lo que se diagnostico paquimeningitis hipertrofica idiopatica y se inicio tratamiento de nuevo con corticoides. En el seguimiento posterior, la paciente presento nuevas lesiones en diferentes localizaciones y mal control algico, por lo que se añadio tratamiento inmunomodulador. Ante la asociacion de hipofisitis linfocitaria y paquimeningitis hipertrofica, se completo el estudio con determinacion de la IgG4 en el suero, que resulto negativa. Conclusiones. La asociacion de hipofisitis linfocitaria y paquimeningitis hipertrofica con las patologias relacionadas con la IgG4 se ha descrito recientemente. A pesar de que en nuestra paciente no se ha confirmado el diagnostico, se debe considerar esta relacion en aquellos casos idiopaticos y, sobre todo, si se asocian otras manifestaciones sistemicas.

    Introduccion. La efectividad y seguridad del fingolimod en pacientes con esclerosis multiple remitente recurrente (EMRR) se demostro en ensayos clinicos. Sin embargo, por las limitaciones de estos, es importante saber como se comporta en condiciones de practica clinica habitual. Asi, el objetivo de este estudio es evaluar la efectividad y seguridad del fingolimod despues de 12 meses de uso en la practica clinica en Galicia. Pacientes y metodos. Estudio retrospectivo y multicentrico (n = 8) de pacientes con EMRR y tratados con una o mas dosis de fingolimod, 0,5 mg/dia. Se evaluo la efectividad –tasa anualizada de brotes (TAB), cambio en la puntuacion de la escala expandida del estado de discapacidad (EDSS), porcentaje de pacientes libres de brotes, libres de progresion de discapacidad y libres de actividad en resonancia– para el total de pacientes y segun tratamiento previo. Se evaluo la seguridad a partir del porcentaje de pacientes que discontinuaron y que presentaron efectos adversos. Resultados. Despues de 12 meses de uso, el fingolimod redujo un 87% la TAB (de 1,7 a 0,23; p < 0,0001) y, en consecuencia, un 81% de pacientes estuvo libre de brotes. La puntuacion de la EDSS disminuyo un 9%. Un 91% de pacientes estuvo libre de progresion de discapacidad y un 72%, libre de actividad en resonancia. En el 43% de los pacientes no se evidenciaron signos de la actividad de la enfermedad. La mayoria de los beneficios del fingolimod difirieron segun el tratamiento previo. Alrededor de un tercio de los pacientes comunicaron efectos adversos, pero solo el 2% discontinuo debido a ellos. Conclusiones. La mayoria de los resultados de efectividad de los ensayos clinicos del fingolimod se observa durante los 12 primeros meses de tratamiento en la practica clinica. Se observo un mejor perfil de seguridad al comunicado en los ensayos clinicos.

    Epithelial ovarian cancer is one of the increasingly incident malignancies that is notorious because of its evasiveness for early diagnosis and high mortality rates. Epithelial ovarian cancers are highly dependent on pathologic vasculature and Vascular Endothelial Growth Factor is known to be one of the most efficient angiogenic factors. Polymorphisms of the VEGF gene, in this study, were assessed for association with the malignancy and other clinico-pathological factors. 300 case samples and 320 age and mensus status matched controls were inculcated into the study. rs699947, rs833061, rs1570360, rs2010963, rs1413711 and rs3025039 were the six single nucleotide polymorphisms that were scrutinized. Genotyping was carried out by polymerase chain reaction and restriction fragment length polymorphism. rs 3025039 showed immense promise as a marker for disease aggression and recurrence and a factor for poor prognosis. rs699947 showed least association with the disease and clinico-pathologic factors studied. rs833061, rs 1570360 showed significant association with some clinico-pathological factors such as bilateral affliction of ovaries and post operative CA-125 levels. rs2010963 associated with presence of ascites in higher volumes. The SNPs under consideration showed no formidable linkage in our study samples. A haplotype analysis (excluding rs699947 and rs1413711) revealed 5 frontrunners being present in >85% of the population with TGGC and CGCC associating significantly as protective and risk factors respectively. These haplotypes showed a dose dependent additive effect of their seeming functionality. This study is unique and a first of its kind carried out in the Indian population of South-east Asia.

    In this work we have demonstrated for the first time on the clinico-genetic material association between hereditary sick sinus node syndrome (SSNS) ADRA2B and eNOS genes polymorphisms. We have established predominance of homozygote genotype of more rare DD allele in patients with SSNS (28%) compared with subjects of control group (8.99%). We have found predominance of heterozygote genotype 4a/4b in patients with SSNS compared with subjects of control group (41.8 and 25.39%, respectively). The data obtained allow to suggest that eNOS gene polymorphism might be associated with SSNS.

    1975-10-27

    Infantile thalamic degeneration is a rare clinico-pathological entity. Restricted location of the lesion and peculiar cytopathological changes serve to distinguish this disorder from other common encephalopathies. Optical and ultrastructural studies demonstrate cytoplasmic calcopherules in previously viable cells. According to current concepts of acute cellular reactions to injury and mechanism of intracellular calcification, the cytological changes cannot be attributed to either hypoxic ischemic cell change or dystrophic calcification. By analogy to other human and pathological material, the most likely basis for nondystrophic calcopherule formation is toxic or infectious injury with local synthesis, or autophagic or phagolysosomal degradation of cellular debris of specific chemical composition favoring calcium deposition.

Under study there were groups of the addicts comparable in the age, form and duration of the disease, and the degree of personality degradation. The data obtained show that it is preferable to individualize the application of the psychotropic means and combinations with regard to the changes in the addicts' psychics, characteristics of their premorbid personality, and the course of the disease in each particular case.

    2016-01-01

    Abstract Skeletal dysplasias are a heterogeneous group of conditions associated with various abnormalities of the skeleton. Some of them are perinatally lethal and can be diagnosed at birth. Lethality is usually due to thoracic underdevelopment and lung hypoplasia. A correct diagnosis and typing of the skeletal disorder is essential for the prognosis as is genetic counseling of the family. A retrospective review of 12 cases of clinico-radiologic diagnosis of skeletal dysplasia, leading to thoracic insufficiency, was conducted. We aimed to make differential diagnosis with special emphasis on radiological findings, and to emphasize the importance of parental counseling. PMID:27057899

    Congenital rickets is a very rare entity in the spectrum of metabolic bone disease in children. The authors report an as yet unreported case of congenital rickets presenting with respiratory distress at birth. The radiographs of long bones and wrist showed generalized osteopenia with cupping and fraying of epiphyseal ends in the second week of life. The patient was managed with very high doses of vitamin D which led to clinico-radiological and biochemical improvement. More than being interesting for its extreme rarity, this report assumes importance as it brings forth the possibility of congenital rickets being a differential diagnosis for a newborn with respiratory distress.

    Ion-channel gene defects are associated with a range of paroxysmal disorders, including several monogenic epilepsy syndromes. Two autosomal dominant disorders present in the first year of life: benign familial neonatal seizures, which is associated with potassium-channel gene defects; and benign familial infantile seizures, for which no genes have been identified. Here, we describe a clinically intermediate variant, benign familial neonatal-infantile seizures, with mutations in the sodium-channel subunit gene SCN2A. This clinico-molecular correlation defines a new benign familial epilepsy syndrome beginning in early infancy, an age at which seizure disorders frequently have a sombre prognosis.

    Introducción: la respuesta inflamatoria causada por sepsis provoca cambios metabolicos que pueden provocar una perdida de masa magra significativa en pacientes septicos. Debido a ello, cuando el tracto digestivo es funcional la terapia nutricional (NT) debe iniciarse dentro de las 48 horas de tratamiento intensivo para reducir la perdida de proteina. Objetivo: evaluar la terapia nutricional enteral (TNE) en pacientes septicos adultos con TNE exclusivo para ≥ 72 horas y duracion de ≥ 7 dias de estancia en la Unidad de Cuidados Intensivos y su relacion con el pronostico clinico. Métodos: se analizaron prospectivamente la adecuacion de la nutricion enteral administrada, los factores asociados con la falta de conformidad, la tolerancia gastrointestinal y el resultado. Se utilizaron pruebas estadisticas de chi-cuadrado y la t de Student, asi como las correlaciones de Mann-Whitney y Spearman y Pearson (p < 0,05). Se ha realizado un modelo de regresion logistica multiple mediante el metodo paso a paso para evaluar la asociacion entre factores de prediccion de la evolucion clinica. Resultados: 53 pacientes, 67,9% hombres y 52,8% ancianos se inscribieron en este estudio. El tiempo promedio para el inicio de ENT fue de 30 (23,5) horas, y el 88,7% de los pacientes alcanzaron el objetivo nutricional en 48 horas. El volumen medio entregado en relacion con el prescrito fue 78,9%. Cuando la muestra se estratifico segun calorias prescritas/administradas, los pacientes que recibieron < 80% tenian una tasa de mortalidad mas alta (p = 0,001) y el consumo de calorias ≥ 80% fue el factor determinante en el pronostico clinico de los pacientes (p = 0,021). Conclusión: los pacientes septicos recibieron nutricion enteral precoz. El objetivo nutricional y el volumen medio entregado en relacion con el volumen prescrito cumplen las directrices de cuidados intensivos. El soporte nutricional se asocio con el resultado clinico y la ingesta calorica ≥ 80% para determinar el pronostico

    Breast cancer is a complex molecular disease comprising several biological subtypes. However, daily routine diagnosis is still based on a small set of well-characterized clinico-pathological variables. Here, we try to link the two worlds of surgical pathology and multilayered molecular profiling by analyzing the relationships between clinico-pathological phenotypes and mutational loads of breast cancer. We evaluated the number of mutated genes with somatic non-silent mutations in different subgroups of breast cancer based on clinico-pathological, including immunohistochemical and tumour characteristics. The analysis was performed for a cohort of 687 primary breast cancer patients with mutational profiling, gene expression and clinico-pathological data available from The Cancer Genome Atlas (TCGA) project. The number of mutated genes was strongly positively associated with higher tumour grade (p = 1.4e-14) and with the different immunohistochemical and PAM50 molecular subtypes of breast cancer (p = 1.4e-10 and p = 4.3e-10, respectively). We observed significant associations (|R| > 0.4) between the abundance of mutated genes and expression levels of genes related to proliferation in the overall cohort and hormone receptor positive cohort, including the Recurrence Score gene signature (e.g., MYBL2 and BIRC5). Specific mutated genes (TP53, NCOR1, NF1, PTPRD and RB1) were highly significantly associated with high loads of mutated genes. Multivariate analysis for overall survival (OS) revealed a worse survival for patients with high numbers of mutated genes (hazard ratio = 4.6, 95% CI: 1.0 - 20.0, p = 0.044). Here, we report a strong association of the number of mutated genes with immunohistochemical and PAM50 subtypes and tumour grade in breast cancer. We provide evidence that specific levels of the mutational load underlie different morphological and biological phenotypes, which collectively constitute the current basis of pathological diagnosis

    Duodenal ulcer cure, as a systemic gastroenterologic disease, can be achieved in some patients by the addition of the nootropic drug piracetam to current antisecretory and antihelicobacter therapy. Piracetam corrects vegetative and psychoemotional disorders in duodenal ulcer, normalizes gastric motility, has an antioxidant effect and improves cerebral circulation. An optimal effect on clinico-endoscopic manifestations of recurrent duodenal ulcer was achieved in combination of piracetam with current antisecretory (omeprazole) and antihelicobacter (de-nol, amoxicillin, metronidazole) medicines. Such combination improves both short- and long-term outcomes of duodenal ulcer treatment.

    This clinico-laboratory study showed that antihypoxant remaxol promoted normalization of lipid metabolism in acute peritonitis and significantly reduced membrane-destabilizing events. This resulted in rapid elimination of the inflammatory process in the abdominal cavity and lowering of the intensity of endogenous intoxication. This beneficial effect decreased the severity of myocardial lesions and resulted in the normalization of erythrocyte function. It is concluded that the regulatory action of remaxol on lipid metabolism is due to its ability to control free radicals in lipid peroxidation and reduce phospholipase A2 activity. PMID:23285765

    Ataxia is a common neurological syndrome resulting from cerebellar, vestibular or sensory disorders. The recognition and characterisation of sensory ataxia remains a challenge. Cerebellar ataxia is the more common and easier to identify; sensory ataxia is often mistaken for cerebellar ataxia, leading to diagnostic errors and delays. A coherent aetiological work-up is only possible if clinicians initially recognise sensory ataxia. We discuss ways to separate sensory from cerebellar ataxia, the causes of sensory ataxia and the clinico-neurophysiological syndromes causing the sensory ataxia syndromes. We summarise a logical tiered approach as a diagnostic algorithm.

    A clinico-electrophysiological study of motor-coordinatory impairments was carried out in 117 patients with infantile cerebral paralysis. The results obtained suggest a possibility of a slow rate of myelinization, inadequate development of the coordinatory systems due to early damage to the brain associated with the systemic localization of the defect, and the obligatory involvement of extrapyramidal impairments in the realization of pathological dyskinesias. The clinical and electrophysiological examination made it possible to sum up all clinical manifestations of the pathology under a heading "discoordinatory extrapyramidal dyskinesias". PMID:6506951

    Skeletal dysplasias are a heterogeneous group of conditions associated with various abnormalities of the skeleton. Some of them are perinatally lethal and can be diagnosed at birth. Lethality is usually due to thoracic underdevelopment and lung hypoplasia. A correct diagnosis and typing of the skeletal disorder is essential for the prognosis as is genetic counseling of the family. A retrospective review of 12 cases of clinico-radiologic diagnosis of skeletal dysplasia, leading to thoracic insufficiency, was conducted.We aimed to make differential diagnosis with special emphasis on radiological findings, and to emphasize the importance of parental counseling.

    As clinical skills improve and innovative diagnostic techniques become available in the field of dermatology and dermatopathology, new types or additional variants of malignant skin tumors are described. This article reviews the current nomenclature, clinico-pathological features, differential diagnosis, prognostic and therapeutic implications of some new dermato(patho)logical rare emerging skin tumors, including epithelial tumors (squamous cell carcinoma with mucinous metaplasia), adnexal tumors (endocrine mucin-producing sweat gland carcinoma), soft tissue tumors of vascular differentiation (pseudolymphomatous cutaneous angiosarcoma, pseudomyogenic hemangioendothelioma), hematopoietic tumors (blastic plasmacytoid dendritic cell neoplasm) and mixed epithelial/melanocytic tumor (squamomelanocytic tumor).

    Some uncertainties which impact on the quality of exclusive radiation therapy of carcinoma of the cervix and the operational procedures followed to lower treatment inaccuracies, are analyzed. In particular the following phase of radiation therapy are considered: prescription: indication for the dose and volume to be treated with external beam radiotherapy (ERT) or intracavitary brachytherapy (BRT) according to the different forms; planning: definition of procedures for ERT and BRT optimization; implementation: analysis of systems for checking reproducibility and treatment tolerance; follow-up: planning of clinico-instrumental controls of disease evolution and late toxicity.

    We examined the records of 33 patients who presented with the clinico-radiological diagnosis of solitary brain metastasis and no other evidence of tumor dissemination. Length of survival of patients and patterns of treatment failure were analyzed according to the treatment modalities that were used. Both groups were comparable regarding major parameters that affect response and survival in patients with brain metastasis. There did not appear to be any significant advantage to the use of irradiation following excision, at least at the doses employed in this study. We advocate the use of higher doses of irradiation in any curative attempt following total excision of a solitary brain metastasis.

    Antigens of I class HLA system (locus A and B) were investigated in 67 patients of Latvian nationality suffering from juvenile rheumatoid arthritis (JRA). Associations of HLA antigens with juvenile rheumatoid arthritis partially coincided with the ones revealed earlier. Typing established an increased incidence of antigen B27 (p less than 0.01) and gaplotype A2, B40 (p less than 0.01). Antigen B15 possessed a protective action with respect to JRA. Interlocus combinations demonstrated a closer association with the disease than a single antigen. The authors also revealed markers of various clinico-anatomical variants of JRA.

    A method of graphic registration of the length and diameter of vessels of basis cerebri is suggested. The registration is carried out on special cards--punch cards with due account of the structure of the circle of Willis, with subsequent collation of these indices with focal changes in the brain. The method is graphically clear and may be used in research work, as well as in the practice of a pathoanatomist in documentation of an autopsy report and for demonstrations in clinico-anatomical conferences.

    Elevated fractures of skull in pediatric age group are rarely reported in the literature. In view of rarity, we present a series of five cases of elevated skull fracture in pediatric age group. Over a period of 1-year, we operated on five such cases. In this article, we have discussed the mode, mechanism and extent of injury, its clinico-radiological findings, course of the disease, and the management outcome. Four out of five cases improved after surgery and did not suffer any complications. Early recognition and appropriate management of compound elevated fracture in pediatric age group comes with good outcome and prevents unwanted morbidity and mortality. PMID:26889296

    Neurocysticercosis is the most common parasitic infection of the central nervous system caused by larvae of Taenia solium. Spinal cysticercosis is an uncommon site of cysticercal infection, and isolated intramedullary involvement is even rarer. We present a case of 10-year-old girl who presented with gradual onset paraparesis with sensory loss and bowel and bladder incontinence. Magnetic resonance imaging (MRI) of spine revealed a cystic lesion with mural nodule (scolex) which was diagnostic for cysticercosis. Patient was treated with antihelminthic, which led to marked clinico-radiological improvement. PMID:21977090

Efficacy of a lymph node dissection (LND) on a D1 -D2 level was investigated. There was established, that regional lymph nodes affection in gastric carcinoma causes deterioration of indices of general and disease-free survival. In patients without regional metastases the operation conduction with LND D1 have promoted improvement of indices of general and a disease-free survival, and expansion of a LND up to the D2 level did not guarantee the treatment results improvement.

    A structural dynamic analysis of productive disorders in visual perception was attempted on the basis of psychological study of 344 patients. These disorders were studied according to the increasing degree of inadequacy (anisomorphia) of pathological images in respect to real stimula. Considering the differences of such phenomena according to the degree of discrepancy of their perceptive characteristics with the traits of real objects, some successively complicated pathological images were examined, including traditional false recognition, illusions and hallucinations, as well as interlapping intermediate structures. Some pathogenetical mechanisms in the formations of visual illusions are suggested. Clinico-psychopathological parallels are made between disorders of visual perception and disease entities.

    Breast cancer is a complex molecular disease comprising several biological subtypes. However, daily routine diagnosis is still based on a small set of well-characterized clinico-pathological variables. Here, we try to link the two worlds of surgical pathology and multilayered molecular profiling by analyzing the relationships between clinico-pathological phenotypes and mutational loads of breast cancer. We evaluated the number of mutated genes with somatic non-silent mutations in different subgroups of breast cancer based on clinico-pathological, including immunohistochemical and tumour characteristics. The analysis was performed for a cohort of 687 primary breast cancer patients with mutational profiling, gene expression and clinico-pathological data available from The Cancer Genome Atlas (TCGA) project. The number of mutated genes was strongly positively associated with higher tumour grade (p = 1.4e-14) and with the different immunohistochemical and PAM50 molecular subtypes of breast cancer (p = 1.4e-10 and p = 4.3e-10, respectively). We observed significant associations (|R| > 0.4) between the abundance of mutated genes and expression levels of genes related to proliferation in the overall cohort and hormone receptor positive cohort, including the Recurrence Score gene signature (e.g., MYBL2 and BIRC5). Specific mutated genes (TP53, NCOR1, NF1, PTPRD and RB1) were highly significantly associated with high loads of mutated genes. Multivariate analysis for overall survival (OS) revealed a worse survival for patients with high numbers of mutated genes (hazard ratio = 4.6, 95% CI: 1.0 - 20.0, p = 0.044). Here, we report a strong association of the number of mutated genes with immunohistochemical and PAM50 subtypes and tumour grade in breast cancer. We provide evidence that specific levels of the mutational load underlie different morphological and biological phenotypes, which collectively constitute the current basis of pathological diagnosis

    The positive expression of MMP-2 and TIMP-2 were found in esophageal cancer (EC) tissue and correlated with cancer stage and clinico-pathological features of tumor and patients' survival. However, little is known about serum levels of those proteins in EC patients. The aim of the present study was to investigate the diagnostic significance of MMP-2 and TIMP-2 serum levels in EC patients in relation to clinico-pathological features of cancer. The study included 53 EC patients and 92 healthy controls. The serum levels of MMP-2, TIMP-2 and classical tumor markers CEA (carcinoembryonic antigen) and SCC (squamous cell carcinoma antigen) were assayed. The prognostic values and diagnostic criteria for the biomarkers tested were defined. Serum levels of MMP-2, TIMP-2 in EC patients were significantly lower, whereas CEA and SCC significantly higher than in control group. The diagnostic sensitivity of TIMP-2 (57%) was higher than those for other biomarkers tested and increased in combination with SCC (70%). Area under ROC curve for TIMP-2 (0.8698) was larger than for other proteins. In Cox's univariate analysis only SCC serum levels were significant prognostic factors for EC patients' survival. The results suggest the limited value of serum analyses of MMP-2 for tumor staging and prognosis in EC and the better usefulness of TIMP-2 than MMP-2 as a tumor marker in the diagnosis of EC, especially in combined use with SCC.

    Solitary fibrous tumor (SFT) is a mesenchymal neoplasm that has been recognized to occur almost all along the organism. Since its description in 1996 at the meninges, a total of 59 cases of meningeal SFT have been reported. Different authors have emphasized the difficulties in the differential diagnosis with other more frequent meningeal neoplasms such as meningioma or hemangiopericytoma, as the clinico-radiological characteristics of this lesion seem to be non specific and the morphological features on pathological study may resemble other spindle cell neoplasms. The diffuse and strong reactivity for CD34 and the negativity for EMA and S-100 are data allowing the diagnosis of SFT. We report the case of a 50-year-old woman suffering from headache, in whom MRI study showed a tentorial lesion initially thought to be a meningioma. In spite of morphological similarities with a fibrous meningioma, inmunohistochemical study finally led to the diagnosis of SFT. As occurred in previous cases, the findings in our patient reflect the similarities in clinico-radiological and pathological characteristics between meningeal SFT and other spindle cell meningeal neoplasms, mainly fibrous meningioma. When a clear diagnosis cannot be done based on typical findings on conventional hematoxylin-eosin study, inmunohistochemical study should be performed in meningeal spindle cell lesions to exclude SFT.

En la mayoria de casos, el corea tiende a mejorar con la edad. Puede asociar hipotiroidismo y problemas respiratorios, como el sindrome de distres respiratorio alveolar neonatal o la enfermedad pulmonar intersticial, ya que TITF1 es un factor de transcripcion esencial para el desarrollo del cerebro, tiroides y pulmon. Casos clinicos. Presentamos el fenotipo clinico de una familia con corea, en la cual dos hermanas presentan hipotiroidismo congenito, y una de ellas, sindrome de distres respiratorio alveolar. En ambas se identifico una mutacion en TITF1 (c.825delC) y se observo mejoria clinica en respuesta al tratamiento con levodopa-carbidopa en dosis bajas. Conclusiones. El corea por mutacion de TITF1 es una causa infradiagnosticada de corea en ninos. Debido a la posibilidad de realizar diagnostico genetico, creemos indicado realizarlo siempre en casos familiares dominantes, teniendo en cuenta la penetrancia variable, asi como en pacientes que presenten afectacion concomitante de pulmon o hipotiroidismo. En casos esporadicos, puede ser recomendable en coreas de causa no filiada, lo que nos permitira evitar otras pruebas, dar un pronostico no degenerativo, permitir un consejo genetico, y hacer ensayos terapeuticos mas dirigidos y eficaces. Por el momento, la levodopa parece el tratamiento sintomatico de eleccion.

El tratamiento farmacologico es una de las opciones terapeuticas en el abordaje de pacientes con acufenos, aunque su eficacia es controvertida. Objetivo. Evaluar el nivel de evidencia que sustenta el uso de diferentes farmacos para reducir la intensidad de los acufenos. Desarrollo. Se han revisado varios grupos farmacologicos incluyendo anestesicos, antiepilepticos, antidepresivos, antihistaminicos, benzodiacepinas, diureticos, corticoides y otras sustancias. La lidocaina intravenosa parece ser eficaz aunque la breve duracion de su efecto y la aparicion de reacciones adversas han llevado a descartarla. La carbamacepina y la gabapentina no han mostrado eficacia frente a placebo, si bien podrian ser eficaces en algunos pacientes con compresion neurovascular o mioclonias. Los antidepresivos triciclicos no son mas eficaces que el placebo aunque pueden mejorar una depresion coexistente. La evidencia es insuficiente para evaluar la eficacia de los inhibidores selectivos de la recaptacion de serotonina y las benzodiacepinas. El acamprosato podria reducir la intensidad de los acufenos, aunque el nivel de evidencia es bajo. No disponemos de resultados consistentes para el tratamiento de los acufenos de la enfermedad de Meniere empleando gentamicina intratimpanica o corticoides. Conclusiones. La utilizacion de medicamentos para reducir la intensidad de los acufenos no esta bien apoyada por ensayos clinicos controlados, aleatorizados y prospectivos. Algunos farmacos son eficaces en algunos estudios, pero la evidencia es limitada. Se necesitan ensayos clinicos aleatorizados mas amplios.

    Background: Herpes zoster (HZ) is a dermatomal viral infection, caused by reactivation of varicella zoster virus (VZV) that persists in the posterior root ganglion. HZ is uncommonly reported in immunocompetent children. It may be due to intrauterine VZV infection or secondary to postnatal exposure to VZV at an early age. Aims: Our study was to review clinico-epidemiological data for HZ in children for early diagnosis and treatment to prevent complications. Materials and Methods: A prospective observational study was conducted from January 2013 to December 2014. Consecutive cases clinically diagnosed as HZ in the pediatric age group were taken up. Results: We report the clinico-epidemiological study of 26 cases of HZ, their benign course and recovery among children. Conclusions: HZ is a rare disease in childhood. Varicella in early childhood is a risk factor of HZ in immunocompromised and immunocompetent children. Childhood zoster occurs in either healthy or underlying immunodeficient children. The appearance of HZ in a young child does not always imply an underlying immunodeficiency or malignancy. But the identification of HZ with or without immunodeficiency is of prime importance from the treatment and prognostic point of view and should be considered in the differential diagnosis of vesicular eruptions. The prognosis is generally good in healthy children. PMID:27688444

    Breast cancers can metastasize via hematogenous and lymphatic routes, however in some patients only one type of metastases are detected, suggesting a certain proclivity in metastatic patterns. Since epithelial-mesenchymal transition (EMT) plays an important role in cancer dissemination it would be worthwhile to find if a specific profile of EMT gene expression exists that is related to either lymphatic or hematogenous dissemination. Our study aimed at evaluating gene expression profile of EMT-related markers in primary tumors (PT) and correlated them with the pattern of metastatic spread. From 99 early breast cancer patients peripheral blood samples (N = 99), matched PT (N = 47) and lymph node metastases (LNM; N = 22) were collected. Expression of TWIST1, SNAI1, SNAI2 and VIM was analyzed in those samples. Additionally expression of CK19, MGB1 and HER2 was measured in CTCs-enriched blood fractions (CTCs-EBF). Results were correlated with each other and with clinico-pathological data of the patients. Results show that the mesenchymal phenotype of CTCs-EBF correlated with poor clinico-pathological characteristics of the patients. Additionally, PT shared more similarities with LNM than with CTCs-EBF. Nevertheless, LNM showed increased expression of EMT-related markers than PT; and EMT itself in PT did not seem to be necessary for lymphatic dissemination. PMID:24217115

    2013-01-01

    Ameloblastomas and adenomatoid odontogenic tumors (AOTs) are common epithelial tumors of odontogenic origin. Ameloblastomas are clinico-pathologically classified into solid/multicystic, unicystic, desmoplastic, and peripheral types, and also divided into follicular, plexiform, acanthomatous, granular types, etc., based on their histological features. Craniopharyngiomas, derived from the remnants of Rathke's pouch or a misplaced enamel organ, are also comparable to the odontogenic tumors. The malignant transformation of ameloblastomas results in the formation of ameloblastic carcinomas and malignant ameloblastomas depending on cytological dysplasia and metastasis, respectively. AOTs are classified into follicular, extrafollicular, and peripheral types. Ameloblastomas are common, have an aggressive behavior and recurrent course, and are rarely metastatic, while AOTs are hamartomatous benign lesions derived from the complex system of the dental lamina or its remnants. With advances in the elucidation of molecular signaling mechanisms in cells, the cytodifferentiation of epithelial tumor cells in ameloblastomas and AOTs can be identified using different biomarkers. Therefore, it is suggested that comprehensive pathological observation including molecular genetic information can provide a more reliable differential diagnosis for the propagation and prognosis of ameloblastomas and AOTs. This study aimed to review the current concepts of ameloblastomas and AOTs and to discuss their clinico-pathological features relevant to tumorigenesis and prognosis. PMID:23837011

    Background This study aimed to clarify the Ki-67 distribution, p53 expression and their relationship with clinico-pathologic features of gastric B cell lymphoma from Northern African population. Methods Twenty paraffin blocks of gastric lymphoma were retrieved from the archival materials of Department of Pathology, Central University Hospital of Sidi Bel Abbes (Western Algeria) from 2007 to 2013. Four µm section specimens were stained by immunohistochemical (IHC) technique with Ki-67 and p53 tumor markers. P values <0.05 were considered statistically significant. Results Expression of p53 proteins and the mean proliferative index (PI) were compared between high grade gastric B cell lymphomas (DLBCL) and low grade gastric B cell lymphomas (gastric MALTs). p53 overexpression (P=0.007) and a high proliferation index Ki-67 (P=0.001) were significantly associated with gastric DLBCL. We found also a statistically significant correlation between p53 and Ki-67 (P=0.007) but no obvious relationships were found between Ki-67 PI and p53 expression as well as clinico-pathological features (age, sex, location, macroscopic type). Conclusions The IHC studies of Ki-67 and p53 expression in gastric B cell lymphoma can help in monitoring of patients at risk, and to give suitable treatment and management of patients.

La presencia de lesiones muy especificas en el polo ocular posterior permitio el diagnostico de EPPMPA complicada con ictus isquemico, probablemente por mecanismo vasculitico. Un amplio estudio etiologico fue negativo para identificar un factor desencadenante claro del proceso. Se inicio tratamiento corticoideo con buena evolucion clinica y radiologica. Conclusiones. La EPPMPA es una entidad rara que generalmente entrana buen pronostico; sin embargo, en algunos casos puede complicarse con afectacion del sistema nervioso central, y el ictus isquemico secundario a vasculitis es la complicacion mas grave. Ante un paciente joven con ictus que presente sintomatologia visual y lesiones coriorretinianas, debe considerarse la EPPMPA en su diagnostico etiologico.

  7. A Prospective Study of Herpes Zoster in Children

    Background: Herpes zoster (HZ) is a dermatomal viral infection, caused by reactivation of varicella zoster virus (VZV) that persists in the posterior root ganglion. HZ is uncommonly reported in immunocompetent children. It may be due to intrauterine VZV infection or secondary to postnatal exposure to VZV at an early age. Aims: Our study was to review clinico-epidemiological data for HZ in children for early diagnosis and treatment to prevent complications. Materials and Methods: A prospective observational study was conducted from January 2013 to December 2014. Consecutive cases clinically diagnosed as HZ in the pediatric age group were taken up. Results: We report the clinico-epidemiological study of 26 cases of HZ, their benign course and recovery among children. Conclusions: HZ is a rare disease in childhood. Varicella in early childhood is a risk factor of HZ in immunocompromised and immunocompetent children. Childhood zoster occurs in either healthy or underlying immunodeficient children. The appearance of HZ in a young child does not always imply an underlying immunodeficiency or malignancy. But the identification of HZ with or without immunodeficiency is of prime importance from the treatment and prognostic point of view and should be considered in the differential diagnosis of vesicular eruptions. The prognosis is generally good in healthy children.

  8. Vulvar endometriosis and Nuck canal.

    2014-12-29

    L’endometriosi è una patologia non ancora del tutto conosciuta che colpisce il 6-10% della popolazione femminile generare e il 35-50% della popolazione femminile affetta da dolore pelvico e infertilità. La sede più frequente di malattia è rappresentata dall’ovaio e ciò sostiene l’ipotesi patogenetica della mestruazione retrograda. Viene descritto un caso di non comune localizzazione vulvare di endometriosi riscontrata in una paziente precedentemente operata per una cisti di Nuck. La donna aveva notato da qualche mese l’insorgenza di una tumefazione nella regione vulvare che le causava dolore e dispareunia che si accentuavano nel periodo mestruale. Il sospetto clinico di endometriosi non aveva avuto conferma negli esami strumentali preoperatori che non avevano evidenziato alterazioni patognomoniche, nè differenze dei reperti in fase pre mestruale e mestruale. Solo l’esame istologico della neoformazione asportata ha confermato la diagnosi. Inoltre gli Autori con la presente nota desiderano sottolineare come nella patogenesi dell’endometriosi vulvare debba essere tenuta in considerazione la presenza della pervietà del dotto peritoneovaginale o dotto di Nuck. Nel caso clinico descritto, infatti, la paziente era stata sottoposta due anni prima ad asportazione di una cisti di Nuck con obliterazione del dotto peritoneovaginale. Tuttavia già in quella fase clinica poteva essersi determinato un impianto endometriosico, che si era poi evidenziato con la formazione del nodulo in sede vulvare asportato chirurgicamente.

    Sommario PREMESSA: L'ecografia del torace soltanto di recente ha assunto una sua completa dignità di metodica diagnostica: esperti ecografisti, con esperienza pneumologica, hanno, infatti, dimostrato la possibilità di una applicazione degli ultrasuoni in ambito toraco-polmonare, soprattutto in situazioni critiche, quali quelle emergenti in urgenza, in terapia intensiva o in ambito pediatrico o in corso di gravidanze. SCOPO: Da queste premesse si origina il lavoro, che si propone di individuare, se esistenti, gli aspetti ultrasonografici delle polmoniti interstiziali a genesi infettiva, e il ruolo di supporto (alla radiologia) degli ultrasuoni anche in questo ambito. MATERIALI E METODI: Sono stati studiati 55 soggetti afferiti, nel quinqennio 2001–2006, alla UOS di Ecografia toracica (UOC Pneumologia I) dell'Ospedale M. Santo e dell'UOS di Ecografia Internistica (UOC di Medicina Generale) dell'Ospedale di Rogliano dell'AO di Cosenza, perché affetti da sospetta patologia infettiva respiratoria virale o simil-virale. Tali pazienti sono stati valutati con indagini clinico-funzionali e strumentali (anamnesi + es. obiettivo + esami ematochimici + prove di funzionalità respiratoria + broncoscopia + Rx e HRTC del torace) e con esame ecografico, in cieco, del torace. RISULTATI: Dalla valutazione comparativa tra dati clinico-laboratoristico-strumentali e dati ecografici è emerso che i 55 soggetti studiati sono risultati affetti da polmonite interstiziale. In tali soggetti la diagnosi è stata formulata con l'ausilio delle comuni tecniche di studio, ma anche l'esame US ha permesso la individuazione di segni considerati diagnostici (Lichtenstein) di patologia interstiziale. Dei soggetti esaminati, infatti, 31 (56,36%) hanno mostrato all'ecografia la presenza di artefatti a coda di cometa (>5 per lato) nelle regioni anteriore e laterale del polmone (dato patognomico di patologia interstiziale) e 24 (46,64%) di “quadri misti” (aree di addensamento

  10. A lactate shuttle system between tumour and stromal cells is associated with poor prognosis in prostate cancer

    PubMed Central

    2014-01-01

    Background In a malignant tumour, cancer cells are embedded in stromal cells, namely cancer-associated fibroblasts (CAFs). These CAFs are now accepted as important players in cancer dynamics, being involved in tumour growth and progression. Although there are various reports on the interaction between tumour and stromal cells, the clinico-pathological significance of this cross-talk is still largely unknown. In this study, we aimed to characterise the expression of key metabolic proteins involved in glucose transport, pyruvate/lactate shuttle system, glycolytic metabolism and fatty acid oxidation in CAFs and tumour cells in different stages of malignant transformation. We further aimed to contextualise the clinico-pathological significance of these protein expression profiles with reference to known prognostic indicators, including biochemical recurrence in pT stage. Methods Prostate tissues were obtained from 480 patients with a median age of 64 years following radical prostatectomy with no previous hormonal therapy. Tissues were analysed for the expression of several key metabolism-related proteins in glands and surrounding fibroblasts by immunohistochemistry. Reliable markers of prognosis such as pT stage and biochemical recurrence were assessed for each case. Results We observed that prostate cancer cells did not rely mainly on glycolytic metabolism, while there was a high expression of MCT4 and CAIX - in CAFs. This corroborates the hypothesis of the “Reverse Warburg effect” in prostate cancer, in which fibroblasts are under oxidative stress and express CAIX, an established hypoxia marker. We found that alterations in the expression of metabolism-related proteins were already evident in the early stages of malignant transformation, suggesting the continuing alteration of CAFs from an early stage. Additionally, and for the first time, we show that cases showing high MCT4 expression in CAFs with concomitant strong MCT1 expression in prostate cancer (PCa

    The peculiarities of cytokines as compounds of immunogenesis are shown in the patients having acute (A) and chronic (Ch) pyelonephritis (PN). The combination of antibacterial therapy with Nukleinat and Galavit promotes the positive changes of cytokin-producing ability of immunocompetent cells and decrease in the level of proinflammation cytokines in blood and urine, secretory leucocyte protease inhibitor (SLPI) in urine. In children with PN and adult patients with diagnostically elevated titres of antibodies (IgG) to Herpes simplex virus, Cytomegalovirus are shown the positive effects of Kanephron® H and Proteflazidum, accordingly. Clinico-immunological effects of immunomodulators testify to the expediency of this usage in complex therapy with the aim to modulate the cytokine link of immunity for improvement of the effective treatment in APN and the protection against aggravation of kidney functioning in ChPN.

According to the most important variants of human contact with the environment abnormal with regard to the content of trace elements, the following types of diseases are distinguished: (1) natural, (2) technogenic, and (3) iatrogenic. In their turn, technogenic diseases are subdivided into industrial, neighbouring, transgressive. Among these diseases, monomicroelementoses and polymicroelementoses should be distinguished. The former include fluorosis, arsenosis, berilliosis, cadmium nephropathy, cobalt myocardiopathy, etc., the latter anemias of biogeochemical nature, endemic goiter, tooth caries, urolithiasis, selenium-deficient myocardiopathy, and others.

    This article narrates a multifaceted educational journey undertaken by a medical student through a weekly SCRAPS (surgery, clinical disciplines, radiology, anatomy, psychiatry and laboratory sciences) clinico-pathological meeting held in the College of Medicine & Health Sciences at Sultan Qaboos University in Muscat, Oman. Through a presentation titled ‘Unveiling Cancer’, the multidisciplinary and interprofessional audience witnessed a simulated interaction between a medical student, a technologist peer and tutors in medicine, pathology and radiology. The presentation was based on the complexities of presentation, diagnosis and management of a patient with anaplastic large cell lymphoma, a rare type of non-Hodgkin lymphoma, in the aftermath of a bone marrow transplantation. After describing the case, the student shared with the audience a spectrum of learning objectives, which included integration in the complex world of contemporary medicine, insight into the triumphs and travails of technology (immunohistochemistry) and peer collaboration, communication and mentorship.

    2013-01-01

    Osteochondroma (OC) of temporo mandibular joint is a rare, slow growing, benign tumor that causes a progressive enlargement of the condyle, usually resulting in facial asymmetry, temporo mandibular joint (TMJ) dysfunction, limited mouth opening and malocclusion. Pain is rarely associated with this tumor. OC is composed of cartilaginous and osseous tissues. Radiographically, there is unilaterally enlarged condyle usually with an exophytic outgrowth of the tumor from the condylar head. We present a rare case of osteochondroma of right mandibular condyle in a 45-year-old male who reported with painless swelling over TMJ area and progressive limited mouth opening. Panoramic radiograph and computed tomography (CT) was performed for better evaluation of the pathological condition. This paper describes the clinico-radiographic features and differential diagnosis of OC. PMID:24082753

    Health status, the way of life and nourishment of 84 vegans in Siberian village (Krasnoyarsk region) were studied and compared with those of 26 meat-eaters. The investigation included work with a questionnaire, clinico-diagnostic and laboratory research. It was shown that a vegetarian diet improves the serum lipid spectrum (cholesterol, LPLD, cholesterol of LPNP, atherogenic coefficient), normalizes weight and cardiovascular system. The vegans had normal levels of vitamin B12 and serum Fe but the calcium level in this group was lowered as compared with the control group. The pathology of internals (nephroptosis, lithic diathesis, tendency to lithogenesis) was observed. Apparently, the high serum Zn levels found in both groups aren't directly caused by the diet but by climate and geographic factors.

We report a new case of a 41-year-old woman with a suprasellar chordoid glioma with histological, immunohistochemical and ultrastructural studies. We discuss the differential diagnosis between chordoma, chordoid meningioma, germinoma and pituitary adenoma. Histologically, the tumour showed cords and lobules of isomorphic epithelioid cells in a vacuolated matrix with prominent multifocal lymphoplasmacytic infiltrates in which some histiocytes and isolated Touton-type giant cells were seen; cells were immunoreactive for glial fibrillary acidic protein but negative for epithelial membrane antigen. Ultrastructural examination revealed abundant intermediate filament but no desmosomes, microvilli nor cilia were seen.

Chondroblastoma of the calcaneum is uncommon and its association with secondary aneurysmal bone cyst is even rarer. Only two cases of calcaneal chondroblastoma associated with secondary aneurysmal bone cyst have been reported till date. A 22-year-old male presented to the department of orthopaedics with complains of pain and swelling in the left heel since the last 10 months. On clinico-radiological grounds differentials considered were giant cell tumour of bone and aneurysmal bone cyst. In view of the histopathological findings of bone curettage and results of special stain and immunohistochemical marker, final diagnosis of chondroblastoma with secondary aneurysmal bone cyst, left calcaneum was rendered. Although rare, chondroblastoma should always be considered in osteolytic lesions of calcaneum. The identification of secondary aneurysmal bone cyst component is important as it has higher chances of recurrence than usual chondroblastoma.

    The exposure of the human population to environmental contaminants is recognized as a significant contributing factor for the development of Parkinson’s disease (PD) and other forms of parkinsonism. While pesticides have repeatedly been identified as risk factors for PD, these compounds represent only a subset of environmental toxicants that we are exposed to on a regular basis. Thus, non-pesticide contaminants, such as metals, solvents, and other organohalogen compounds have also been implicated in the clinical and pathological manifestations of these movement disorders and it is these non-pesticide compounds that are the subject of this review. As toxic exposures to these classes of compounds can result in a spectrum of PD or PD-related disorders, it is imperative to appreciate shared clinico-pathological characteristics or mechanisms of action of these compounds in order to further delineate the resultant disorders as well as identify improved preventive strategies or therapeutic interventions.

    Ciliated foregut cyst of gallbladder is a very rare benign cystic lesion. A 39-year-old woman was referred to our hospital after abdominal ultrasonography revealed a cystic lesion of gallbladder. On abdominal ultrasonography and computed tomography, a unilocular cystic lesion was found at right upper quadrant with attachment to the gallbladder neck. The gallbladder with cystic lesion was resected through laparoscopic cholecystectomy. The cystic lesion revealed a unilocular cyst with ciliated cuboidal or columnar epithelium and abundant goblet cells. Pathologic examination is essential to distinguish from other cystic lesions of the gallbladder and avoid unnecessary additional treatment. In the current case report, we presented the clinico-pathologic findings of the ciliated foregut cyst of the gallbladder and review of literature. PMID:27212997

    A cervical disc herniation (CDH) is a frequently encountered pathology in primary care medicine. It may give rise to a compression of a nerve root (a radiculopathy, with or without sensory-motor deficit) or of the spinal cord (myelopathy). The majority of CDHs can be supported by means of a conservative treatment. When a radiculopathy is found and a clinico-radiological correlation is present, a moderate neurological deficit appears suddenly, or if it is progressive under conservative treatment or if pain is poorly controlled by well-conducted conservative treatment performed during 6 to 8 months, surgery is then recommended. A symptomatic cervical myelopathy is, by itself, an indication for a surgical treatment. PMID:26672182

    Oncology is undergoing a data-driven metamorphosis. Armed with new and ever more efficient molecular and information technologies, we have entered an era where data is helping us spearhead the fight against cancer. This technology driven data explosion, often referred to as "big data", is not only expediting biomedical discovery, but it is also rapidly transforming the practice of oncology into an information science. This evolution is critical, as results to-date have revealed the immense complexity and genetic heterogeneity of patients and their tumors, a sobering reminder of the challenge facing every patient and their oncologist. This can only be addressed through development of clinico-molecular data analytics that provide a deeper understanding of the mechanisms controlling the biological and clinical response to available therapeutic options. Beyond the exciting implications for improved patient care, such advancements in predictive and evidence-based analytics stand to profoundly affect the processes of cancer drug discovery and associated clinical trials.

    Objective: The aim of our study is to assess the clinico-electrophysiological profile of children with Guillain–Barré syndrome (GBS) in Upper Egypt and to compare the efficacy of plasmapheresis versus other treatment modalities. Patients and methods: This was a retrospective study of children from January 2010 to October 2014 diagnosed as GBS. It included 62 cases. Results: Acute inflammatory demyelinating polyradiculoneuropathy (AIDP) was the most prevalent type of GBS in our locality. As regards the treatment, 32 cases received plasmapheresis while 30 patients received intravenous immunoglobulin. We found a significant decrease in the duration of hospitalization and a significant increase in the number of children with complete recovery in cases treated with plasmapheresis. Conclusion: GBS is not uncommon in children of Upper Egypt, with AIDP the most prevalent type. Plasmapheresis is the best treatment modalities for GBS as it reduces the duration of hospital stay and hastens the recovery of those children. PMID:26788127

    Quantitative and qualitative differences were demonstrated in the amount of virus in a range of tissues from pigs infected with either the Weybridge or New South Wales (NSW) strains of hog cholera (HC) virus. The titre of the Weybridge strain in samples, as assessed by either virus titration in cell culture or by the density of specific fluorescing cells in tissue sections, was higher than that for the NSW strain. This correlated with the greater severity of the clinico-pathological syndrome induced by the Weybridge strain. The implications of the differences in the virus content of tissues in the diagnosis of HC is discussed as is the use of monoclonal antibodies to differentiate HC and bovine virus diarrhoea viruses.

Characteristic histopathology, immunohistochemistry in the tissue, protein chemistry, and raised serum IgG4 were supportive for the diagnosis. As this newly diagnosed disease has multi-organ affection and little is known about its pathogenesis particularly in eye and adnexa, the present case will open many challenges in clinico-pathological diagnosis and research in the future.

    A45-year previously known hypertensive lady presented with 2-year history of upper abdominal pain, heaviness, and weight loss. Her radiological assessment suggested the possibility of hepatoma or liver metastases. Considering her age, overall good health and absence of cirrhosis, a liver biopsy was taken which showed hepatic epithelioidhaemangioendothelioma (HEHE), a rare and unusual intermediate grade vascular tumor which can easily be confused with hepatoma or metastatic liver disease. To the best of their knowledge, the authors are most probably reporting the first ever case of HEHE from Pakistan with special emphasis on its clinical presentations, clinico-radiological diagnostic clues, and the management options in the light of the limited retrospective studies.

    Chlamydia trachomatis is considered a major aetiological agent of conjunctivitis in newborns. The objective of the present study was to determine the aetiology of neonatal conjunctivitis and clinico-epidemiological correlates of chlamydial ophthalmia neonatorum. Fifty-eight newborns with signs and symptoms of conjunctivitis were studied. Conjunctival specimens were subjected to Gram staining, routine bacteriological culture, culture for Neisseria gonorrhoeae and direct fluorescent antibody (DFA) staining for diagnosis of C. trachomatis infection. C. trachomatis was detected in 18 (31%) neonates. Findings suggest that since C. trachomatis is the most common cause of neonatal conjunctivitis, routine screening and treatment of genital C. trachomatis infection in pregnant women and early diagnosis and treatment of neonatal Chlamydial conjunctivitis may be considered for its prevention and control.

    A safe, moderately reactogenic and immunologically effective scheme of complex (combined) immunization against meningitis A, diphtheria, typhoid fever, viral hepatitis A and influenza has been developed as the result of experimental and clinico-immunological studies. Depending on the epidemiological situation, the newly developed scheme can be used in two variants. According to the first variant of this scheme, the following preparations are injected subcutaneously into three different sites: a mixture of group A meningococcal vaccine and diphtheria toxoid, typhoid vaccine and influenza vaccine. The second variant of the scheme differs from its first variant in using intramuscular injection of normal human immunoglobulin instead of injection of influenza vaccine. Moreover, in practical realization these variants may be altered by excluding vaccines, unnecessary under present conditions. The newly developed scheme of vaccinal prophylaxis is recommended for practical use. PMID:8067144

    Clinico-biological examination of 50 alcoholic patients was carried out. 30 patients were treated with lerivon (L) during 1 month. 15 control patients received amitriptylin for 1 month and 15 patients received relanium for 7 days. It was determined that L was quite effective in treatment of depression in alcoholic patients. The main L effects were anxiolytic, antidepressive and hypnotic. The drug also decreased alcohol addiction, had vegetostabilising and sedative effects. The conclusion was made on pathogenetic action of L in alcoholism: It influences upon dopaminergic mediation in catecholamine system. Administration of L permitted to normalize neurochemical processes underlying alcohol addiction and depression. L was well tolerated. Side effects complications, drug addiction were not registered.

    Postmortem studies of synapses in human brain are problematic due to the axial resolution limit of light microscopy and the difficulty preserving and analyzing ultrastructure with electron microscopy. Array tomography overcomes these problems by embedding autopsy tissue in resin and cutting ribbons of ultrathin serial sections. Ribbons are imaged with immunofluorescence, allowing high-throughput imaging of tens of thousands of synapses to assess synapse density and protein composition. The protocol takes approximately 3 days per case, excluding image analysis, which is done at the end of the study. Parallel processing for transmission electron microscopy (TEM) using a protocol modified to preserve structure in human samples allows complimentary ultrastructural studies. Incorporation of array tomography and TEM into brain banking is a potent way of phenotyping synapses in well-characterized clinical cohorts to develop clinico-pathological correlations at the synapse level. This will be important for research in neurodegenerative disease, developmental diseases, and psychiatric illness. PMID:23787894

    Actoprotectors are preparations that enhance body stability against physical loads without increasing oxygen consumption or heat production. Or, in short, actoprotectors are synthetic adaptogens with a significant capacity to improve physical performance. This paper explores the history of actoprotectors’development, their pharmacological properties, mechanism of action, and practical application to the improvement of mental and physical performance. A brief summary of the clinico-pharmacological characteristics of the main representatives of this class (bemitil and bromantane) is provided. Some other synthesized compounds, and even natural ones such as ginseng, also are regarded as potential actoprotectors, and these are treated herein as well. Actoprotectors, owing to their wide-ranging pharmacological activities, high efficiency and safety, can be applied under either normal or extreme conditions. PMID:24009833

    We report the case of a 13-year-old girl, with a cerebral venous thrombosis treated initially by heparin. In front of this early thrombocytopenia, in spite of the absence of preliminary treatment by heparin, the "heparin-dependent" anti-PF4 antibodies ELISA assay was realized and turned out to be strongly positive. In spite of the negativity of the specific functional tests, the heparinotherapy was substituted by a treatment by danaparoïd of sodium, allowing a clinico-biological improvement. Because of the low score of HIT imputability, we realized a specific antibodies anti-PF4 alone assay which was strongly positive. This specific positivity probably explains the positivity of the antibodies anti PF4 "heparin-dependent" assay. The originality of this case lies in the young age of the patient and in the probably pathogenic character of these unusual antibodies, in addition markers of an auto-immune disease. PMID:21159583

    High developmental dysplasia of the hip is commonly treated with total hip arthroplasty and shortening osteotomy. We present a two stage technique, consisting of progressive femoral lowering followed by total hip arthroplasty. The clinico-radiographic results of eleven patients (twelve hips) who were operated on with the two-stage technique were evaluated at a mean follow-up of 11 ± 5 years. At the final follow-up, ten patients (eleven hips) had a mean Harris hip score of 85 ± 5 points with no implant loosening. One patient (one hip) was revised at 5 years due to infection. No neurovascular complications were observed in any patients. With this technique, we could place the cup in the anatomical position and obtain complete limb symmetry with excellent clinical results at long-term. PMID:25599863

  1. RON is not a prognostic marker for resectable pancreatic cancer

    PubMed Central

    2012-01-01

    Background The receptor tyrosine kinase RON exhibits increased expression during pancreatic cancer progression and promotes migration, invasion and gemcitabine resistance of pancreatic cancer cells in experimental models. However, the prognostic significance of RON expression in pancreatic cancer is unknown. Methods RON expression was characterized in several large cohorts, including a prospective study, totaling 492 pancreatic cancer patients and relationships with patient outcome and clinico-pathologic variables were assessed. Results RON expression was associated with outcome in a training set, but this was not recapitulated in the validation set, nor was there any association with therapeutic responsiveness in the validation set or the prospective study. Conclusions Although RON is implicated in pancreatic cancer progression in experimental models, and may constitute a therapeutic target, RON expression is not associated with prognosis or therapeutic responsiveness in resected pancreatic cancer.

    We performed clinico-pathological evaluations of 11 wild Agassiz's desert tortoises (Gopherus agassizii) from a translocation project in the central Mojave Desert, California, USA. Group 1 consisted of nine tortoises that were selected primarily due to serologic status, indicating exposure to Mycoplasma testudineum (seven) or both M. agassizii and M. testudineum (two), and secondarily due to clinical signs of upper respiratory tract disease (URTD). Group 2 consisted of two tortoises that were antibody-negative for Mycoplasma and had no clinical signs of URTD, but did have other signs of illness. Of the Group 1 tortoises, M. testudineum, but not M. agassizii, was amplified by polymerase chain reaction and DNA fingerprinted from two tortoises. Using light microscopy, mild to severe pathologic changes were observed in one or more histologic sections of either one or both nasal cavities of each tortoise in Group 1. Our findings support a causal relationship between M. testudineum and URTD in desert tortoises.

    Sporadic cerebral amyloid angiopathy (CAA) is a cerebral small vessel disease in the elderly. Neuropathologically, it is characterized by deposition of amyloid-ß (Aß) in the wall of small to medium-sized arteries, capillaries and venules of the cerebral cortex and leptomeninges. Over the last years it was recognized as an important cause of spontaneous intracerebral hemorrhage and cognitive deficits in the elderly. The clinical and radiological manifestations are diverse ranging from acute onset focal neurological deficits due to intracerebral lobar hemorrhage to subacute progressive cognitive impairment due to Aß-mediated inflammation confluent subcortical edema. The wide clinico-radiological spectrum of CAA is a major challenge for the neurologist and stroke physician. This review provides a structured and detailed look at recent developments in CAA, and is illustrated with case studies. PMID:27607067

    Apoplexy in sellar metastasis is very rare with only a few case reports in literature. A case of apoplexy in sellar metastasis from follicular thyroid carcinoma is reported and the literature is briefly reviewed. The patient presented with sudden onset headache and bi-lateral loss of vision following thyroidectomy in a case of follicular carcinoma thyroid with proven sellar metastasis. CT scan showed hyperdense blood in sellar mass suggestive of apoplexy in sellar metastasis. The patient underwent early trans-sphenoidal decompression. Apoplexy in sellar metastasis, although very rare, can be clinico-radiologically indistinguishable from pituitary apoplexy and should be especially considered in the differential diagnosis of patients with known primary neoplastic disease. In view of similar patho-physiological mechanism, sellar metastasis with apoplexy should be managed in a similar manner as pituitary apoplexy. PMID:21534208

    Despite being one of the most common oral mucosal diseases and recognized as early as 1866, oral lichen planus (OLP) is still a disease without a clear etiology or pathogenesis, and with uncertain premalignant potential. More research is urgently needed; however, the research material must be based on an accurate diagnosis. Accurate identification of OLP is often challenging, mandating inclusion of clinico-pathological correlation in the diagnostic process. This article summarizes current knowledge regarding OLP, discusses the challenges of making an accurate diagnosis, and proposes a new set of diagnostic criteria upon which to base future research studies. A checklist is also recommended for clinicians to provide specific information to pathologists when submitting biopsy material. The diagnostic process of OLP requires continued clinical follow-up after initial biopsy, because OLP mimics can manifest, necessitating an additional biopsy for direct immunofluorescence study and/or histopathological evaluation in order to reach a final diagnosis.

El tratamiento quirurgico de la hidrocefalia es uno de los procedimientos quirurgicos mas habituales en la neurocirugia pediatrica, y las derivaciones ventriculoperitoneales constituyen una herramienta fundamental en el tratamiento de la hidrocefalia tanto infantil como del adulto. Las complicaciones de las valvulas son relativamente frecuentes, sobre todo en la poblacion pediatrica, y, entre estas, las mas habituales incluyen: las obstrucciones, las desconexiones, el hiperdrenaje y las infecciones. Caso clinico. Niña de 7,5 años, portadora de una valvula ventriculoperitoneal, que presentaba cefalea intermitente. Un estudio con tomografia computarizada demostro una lesion quistica temporal derecha. Tras la revision valvular, la tomografia computarizada evidencio la reduccion del quiste. Conclusiones. La formacion de una cavidad porencefalica es una complicacion poco frecuente. Se relaciona con problemas en el cateter distal en pacientes con ventriculos dilatados y de las que existen escasas referencias en la bibliografia.

    Invasive pulmonary aspergillosis (IPA) is a disease of immunocompromised patients, but its prevalence is increasing in immunocompetent persons. Patients usually present with non-specific symptoms, sometimes consistent with bronchopneumonia. We discuss the case of a 19-year-old boy who presented with constitutional respiratory symptoms along with signs of obstruction of the superior and inferior vena cava. A chest radiograph was suggestive of a thoracic mass raising suspicion of bronchogenic carcinoma/ benign mass, sarcoidosis and tuberculosis, but a diagnosis of invasive aspergillosis was established. The patient showed excellent clinico-radiological improvement with administration of voriconazole. Invasive pulmonary aspergillosis may also present with atypical findings and should be considered in differentials when investigating a case even if the patient does not have a risk factor.

    2014-01-01

    Gastrointestinal stromal tumors (GISTs) are the most frequent mesenchymal tumors of the gastrointestinal tract. The discovery that these tumors, formerly thought of smooth muscle origin, are indeed better characterized by specific activating mutation in genes coding for the receptor tyrosine kinases (RTKs) CKIT and PDGFRA and that these mutations are strongly predictive for the response to targeted therapy with RTK inhibitors has made GISTs the typical example of the integration of basic molecular knowledge in the daily clinical activity. The information on the mutational status of these tumors is essential to predict (and subsequently to plan) the therapy. As resistant cases are frequently wild type, other possible oncogenic events, defining other “entities,” have been discovered (e.g., succinil dehydrogenase mutation/dysregulation, insuline growth factor expression, and mutations in the RAS-RAF-MAPK pathway). The classification of disease must nowadays rely on the integration of the clinico-morphological characteristics with the molecular data. PMID:25593916

    We performed a clinico-statistical study of the maxillofacial fracture due to sports during the period of 15 years between 1977 and 1991. Eighty-nine patients were seen with injuries resulting from 21 different sports. The incidence of the fracture was most common in rugby, followed by ski, baseball and soccer. Males were shown to be more prone to maxillofacial fracture than females (5.4:1) and the highest incidence of injuries involved the 20-29 age group followed by the 10-19 age group. The major parts of the fracture were the mandible and the alveolar process. Conservative therapy such as maxillomandibular fixation was usually performed and the clinical course was good. It was suggested that the prevention of the sports-related fracture and the time of returning to sports after the fracture will require further study.

The clinical signs displayed by the affected animals were ataxia, lethargy, emaciation, hypertonia of the neck muscles, spastic paresis in the hind legs, abnormal postural reactions and death. The clinico-pathologic examination revealed that the affected animals were anemic and their serum level of aspartate aminotransferase was significantly increased. Cytoplasmic vacuolation in the Purkinje cells and pancreatic acinar cells was observed by histological examination. The neuronal lectin binding pattern showed a strong positive reaction to WGA (Triticum vulgaris), sWGA (succinylated T. vulgaris) and LCA (Lens culinaris). Although I. carnea is common in tropical regions, this is the first report of spontaneous poisoning in goats in Argentina. PMID:25728544

It is a chronic inflammatory condition of esophagus often characterized by refractory reflux symptoms in children and dysphagia in adults. It occurs as a result of Th2 inflammatory response to environmental triggers (food antigens) in genetically predisposed individuals. The diagnostic criteria include symptoms of esophageal dysfunction, esophageal eosinophilia (> 15/hpf), and a PPI trial (persistent eosinophilia after 8 weeks of PPI). Mainstay of treatment at present is topical steroids and dietary therapy. Maintenance treatment should be considered to prevent long term complications. PMID:27522734

    Il trattamento conservativo dei trauma splenici è ormai il “gold standard” per i bassi gradi di lesione splenica (III grado), mentre è ancora dibattuta la gestione dei traumi splenici severi (IV-V grado). Controversa rimane la gestione dei traumi splenici di III grado, che potrebbero beneficiare del trattamento conservativo, associato o meno ad angioembolizzazione dell’arteria splenica, in centri specializzati ed idonei alla gestione conservativa dei traumi degli organi parenchimatosi. Le ultime linee guida pubblicate dalla “Eastern Association of Surgery of Trauma” risalgono al 2012 e provvedono a dare solo delle raccomandazioni di livello II-III sulla gestioni dei traumi splenici. Il fattore che maggiormente influenza il successo del trattamento conservativo è la selezione dei pazienti che potrebbero beneficiare di tale gestione. Alla luce di ciò, l’obiettivo primario del nostro studio è di identificare i pazienti con lesioni spleniche post-traumatiche, che dovrebbero essere sottoposti a trattamento conservativo; l’obiettivo secondario è di confrontare il decorso clinico e la durata della degenza nei pazienti trattati conservativamente e in quelli sottoposti a splenectomia. Tutti i pazienti con trauma splenico, ricoverati presso l’U.O. di Chirurgia d’Urgenza dell’Azienda Ospedaliera- Universitaria Sant’Anna, Ferrara (Italia) tra Novembre 2010 (anno in cui è stata istituita l’U.O.) e Dicembre 2014, sono stati inclusi nello studio, per un totale di 54 pazienti. Di questi 54 pazienti, 29 (53.7%) sono stati immediatamente sottoposti ad intervento chirurgico di laparotomia esplorativa e splenectomia, mentre 25 (46.3%) sono stati sottoposti a trattamento conservativo. I pazienti sottoposti ad angioembolizzazione sono stati 9 su 25 (36%). Sono stati raccolti dati epidemiologici, dati riguardanti il decorso clinico e le indagini laboratoristiche e radiologiche a cui i pazienti sono stati sottoposti al momento dell’accesso in Pronto

The role of familial factors in the formation of neurotic states of children is emphasized. The authors consider the time during which the child was exposed to psychotraumatic circumstances and the relationship between the severity of epileptic process in parents and the development of neurotic disorders in their progeny. A conclusion has been made that the disease of the parents can exert both direct and indirect influence on the nervous system of the child, this leading to the development of different neurotic states. The prophylaxis of neurotic disturbances in children should include the creation of healthy psychic atmosphere in families where one of the parents suffers from epilepsy. PMID:3751410

    Epidermal cysts represent the most common cutaneous cysts. They arise following a localized inflammation of the hair follicle and occasionally after the implantation of the epithelium, following a trauma or surgery. Conventional epidermal cysts are about 5 cm in diameter; however, rare reports of cysts more than 5 cm are reported in the literature and are referred as “Giant epidermal cysts.” Epidermal cysts although common, can mimic other common benign lesions in the head and neck area. A thorough clinico-pathologic investigation is needed to diagnose these cutaneous lesions as they differ in their biologic behavior, treatment, and prognosis. We report a case of a giant epidermoid cyst in the scalp area of a young female patient which mimicked lipoma on clinical, as well as cyotological examination. We also present a brief review of epidermal cysts, their histopathological differential diagnosis, and their malignant transformation. PMID:26677303

    A fasting plasma lipid profile investigation was undertaken in 63 women who were on contraception with the 3-monthly intramuscular depo-provera injection for periods ranging from 3 to 30 months. Fifty nulliparous women, with no previous history of contraceptive therapy, matched for age, parity, height and socio-economic status, served as controls. History of clinico-physiological side effects was recorded. The results show reduced levels of fasting plasma cholesterol in patients on depo-provera compared to the control group but there was no significant change in fasting plasma phospholipid levels. Contrary to expectations, the patients on depo-provera had higher fasting plasma triglyceride levels than controls. Excessive weight gain and irregular heavy bleeding represent major reasons for withdrawal from depo-provera therapy. The findings suggest that the alterations in the plasma lipid profile, body weight and side effects experienced by women on depo-provera may be inversely related to the duration of effective therapy.

    A lumbar disc herniation (LDH) is a condition frequently encountered in primary care medicine. It may give rise to a compression of one or more nerve roots, which can lead to a nerve root irritation, a so-called radiculopathy, with or without a sensorimotor deficit. The majority of LDHs can be supported by means of a conservative treatment consisting of physical therapy, ergotherapy, analgetics, anti-inflammatory therapy or corticosteroids, which may be eventually administered by infiltrations. If a clinico-radiological correlation is present and moderate neurological deficit appears suddenly, if it is progressive under conservative treatment or if pain is poorly controlled by well-conducted conservative treatment performed during four to six months, surgery is then recommended.

    The oral cavity contains many organs and tissues compressed in a small area. Accordingly oral tumors have a wide variety of appearances. Reactive hyper-plastic lesions include epulis,morsicatio,traumatic ulcer or palatal hyperplasia. These benign lesions must be separated clinically and histologically from precancerous and neoplastic lesions. In leukoplakia,the individual risk can be estimated by clinical signs. Nevertheless histopathology is mandatory because precancerous lesions usually precede or accompany most oral cancers. Amalgam tattoo,oral nevi and melanoacanthoma have to be considered as differential diagnoses of oral melanoma. Accurate clinico-pathological diagnosis is mandatory to insure appropriate therapy. Oral soft tissue tumors such as Kaposi sarcoma and multiple mucosal neuromas in MEN 2b require interdisciplinary management. Diseases affecting the minor salivary glands which may be encountered by dermatologists include mucocele, necrotizing sialometa-plasia,and tumors such as pleomorphic adenoma.

    A clinico-pathologic and immunologic case study of a 57-year-old woman who has shown progressive lymphoid proliferations and lymphocyte dysfunction over the course of 10 years is presented. Early in the course of her disease, she presented with recurrent benign nasopharyngeal lymphoid tumors. She subsequently developed benign lymphoepithelial lesions involving both a submandibular and then a parotid salivary gland. She eventually underwent pneumonectomy for lymphocytic interstitial pneumonitis with marked cystic degeneration and lung destruction. Although frank malignancy has not been demonstrated review of her nasopharyngeal biopsies and of her pulmonary pathology shows a tendency toward distinct cellular uniformity with loss of follicles and germinal centers. Concurrently, immunologic studies have demonstrated abnormalities of cell mediated (T cell) function.

    We studied nine cases of oncocytic tumors of salivary gland type in order to evaluate their clinico-pathologic profiles and nuclear DNA patterns as criteria for the differential diagnosis between benign and malignant forms. The tumors were located at the parotid gland, palate, and orbit. The age of the patients ranged between 35 and 85 years and the sex ratio (F:M) was 1:0.8. Seven tumors were capsulated and had typical cytology: they were composed of polyhedrical cells with large, eosinophilic, and granular cytoplasm and dark nucleus. The remaining two tumors exhibited malignancy criteria for the oncocytic tumors: atypia, pleomorphism, and mitosis. The evaluation of the nuclear DNA content was also distinct: benign tumors had a DNA diploid pattern and the malignant neoplasms displayed a DNA aneuploid pattern. These observations point to DNA nuclear assessment as an additional criterion to discriminate neoplasms with divergent clinical behavior and prognosis.

    Clinico-pathological studies reveal that some elderly people with no cognitive impairment have high burdens of neurofibrillary tangles (NFTs), a pathology associated with Alzheimer's disease. We examined a total of 123 elderly participants without dementia and free of other neurological disorders or pathologies who at autopsy were classified as Braak NFT stages of I-V. We found that women were significantly more likely to have a high Braak score. Significant associations were found between high Braak scores and entorhinal cortex amyloid load, combined hippocampal and entorhinal cortex amyloid loads with perceptual speed in the low Braak group after adjusting for age, gender and apolipoprotein E ε4 status. Elderly with preserved cognitive function show a wide range of Braak scores and plaque pathology similar to that seen in prodromal and frank Alzheimer's disease at death. These data suggest that some older people with extensive NFT and plaque pathology demonstrate brain resilience or reserve leading to preserved cognitive function.

    Immunoglobulin G4 (IgG4-related diseases) affects various tissues and organs of the human body. Orbital, adnexal, and scleral inflammations were already reported in the medical literature. To the best of our knowledge, we report the first case of intraocular IgG4-associated inflammatory mass in the ciliary body mimicking as a melanoma in a 23-year-old female from Northeast India. Characteristic histopathology, immunohistochemistry in the tissue, protein chemistry, and raised serum IgG4 were supportive for the diagnosis. As this newly diagnosed disease has multi-organ affection and little is known about its pathogenesis particularly in eye and adnexa, the present case will open many challenges in clinico-pathological diagnosis and research in the future.

    In humans, brain connectivity implements a system for language and communication that spans from basic pre-linguistic social abilities shared with non-human primates to syntactic and pragmatic functions particular to our species. The arcuate fasciculus is a central connection in this architecture, linking regions devoted to formal aspects of language with regions involved in intentional and social communication. Here, we outline a new anatomical model of communication that incorporates previous neurofunctional accounts of language with recent advances in tractography and neuropragmatics. The model consists of five levels, from the representation of informative actions and communicative intentions, to lexical/semantic processing, syntactic analysis, and pragmatic integration. The structure of the model is hierarchical in relation to developmental and evolutionary trajectories and it may help interpreting clinico-anatomical correlation in communication disorders.

La neuromielitis optica (NMO) o enfermedad de Devic es un trastorno autoinmune, inflamatorio y desmielinizante del sistema nervioso central, que afecta principal y caracteristicamente al nervio optico y a la medula espinal. Los anticuerpos antiacuaporina-4 (AQ-4) son un biomarcador especifico de esta entidad y, desde su descubrimiento, se ha ampliado el numero de sintomas y datos radiologicos de la enfermedad y se ha definido el concepto de espectro clinico de NMO. Caso clinico. Mujer de 66 años diagnosticada de NMO por haber sufrido brotes de neuritis optica y mielitis de repeticion junto con anticuerpos AQ-4 positivos. Presento un cuadro de disminucion del nivel de conciencia, con resonancia magnetica cerebral que mostro multiples lesiones en la sustancia blanca, sin realce de contraste, que se resolvio sin tratamiento. Un mes despues, sufrio empeoramiento del estado general, sindrome confusional y ceguera. En la resonancia magnetica cerebral se observaron nuevas lesiones en la sustancia blanca y aumento del tamaño de otras ya existentes. Se emitio el diagnostico de encefalopatia en el contexto de NMO y se trato a la paciente con corticoides e inmunoglobulinas intravenosas, con lo que se produjo mejoria clinica y radiologica. Conclusiones. Desde el descubrimiento de los anticuerpos AQ-4, ha aumentado el numero de manifestaciones clinicas y radiologicas de la NMO mas alla de la afectacion del nervio optico y de la medula espinal, entre ellas las manifestaciones cerebrales. Reconocerlas es muy importante para hacer un diagnostico precoz, evitar pruebas complementarias no necesarias e instaurar el tratamiento adecuado.

    Una donna di 57 anni si sottoponeva ad trattamento odontoiatrico per una carie del secondo molare superiore di destra. Durante la visita odontoiatrica veniva utilizzato uno strumento ad aria compressa, secondo lo standard di cura. Improvvisamente, la paziente accusava deglutizione e difficoltà respiratorie ed un notevole gonfiore del viso che coinvolgeva il collo e parzialmente il volto. La paziente veniva pertanto trasportata d’urgenza al Pronto Soccorso con il sospetto di reazione allergica. L’esame clinico rivelava un crepitio palpabile a livello dei tessuti sottocutanei del volto, del collo e della regione pre- sternale senza però rilevare nessun segno di infiammazione, trisma o raccolta di liquidi. Una radiografia del torace prima ed una tomografia computerizzata successivamente confermavano la presenza d’aria nei tessuti molli delle regioni profonde dagli spazi peri-mandibolare e retro-mandibolari e nella zona sub-mascellare e latero –cervicale estendendosi lungo il solco vascolare e nello spazio retrofaringeo discendente fino a livello del mediastino. La paziente veniva quindi sottoposta ad osservazione clinica e monitoraggio respiratorio, e si cominciava la somministrazione endovenosa di antibiotici ad ampio spettro ed analgesici. Il successivo decorso ospedaliero risultava regolare e la paziente veniva dimessa in 5° giornata di ricovero dopo miglioramento del quadro clinico e radiologico. Tre mesi dopo la dimissione, la paziente risultava in buone condizioni cliniche in assenza di recidiva. Come risulta nel caso sopra riportato, l’enfisema sottocutaneo e lo pneumomediastino, sebbene raramente possono essere legati ad alcune manovre odontoiatriche che utilizzano sistemi ad immissione di aria ad alta pressione. Nonostante l’esordio acuto ed la sintomatologia spesso allarmante (al punto da poter essere erroneamente scambiata per una reazione allergica), si tratta di una condizione benigna e sostanzialmente ad auto-risoluzione pur necessitando

    Background: Primary CNS lymphoma (PCNSL), a rare form of aggressive extranodal non-Hodgkin's lymphoma (NHL), has increased in incidence during the last three decades and occurs in both immune compromised and immune competent hosts. It has an overall poor prognosis. Objective: This study attempts to further delineate the clinico-pathological, immunohistochemical and radiological profile of PCNSL at Jeddah to King Faisal Hospital and Research Center. Methods: Computerized search through the archives of King Faisal Hospital and Research Centre between July 2000- December 2012 identified 15 patients with pathologically confirmed PCNSL. These were analyzed retrospectively. Their clinico-pathological, immunohistochemical and radiological data were analyzed. Results: Of the 15 PCNSL patients, 8 (53.3%) were females and 7 (46.6%) were males. There was female predilection especially in the age group of 40-59 years. Mean age at diagnosis for all patients was 50.4 years. There was no patient in the pediatric age group. The most common location in the brain was the frontal region in 7 patients (46.6%), 7 (46.6%) had multiple intracranial masses; all 15 (100%) were Non Hodgkin B-cell lymphomas, among which 13 (86.6%) were diffuse large B-cell lymphomas. All 15 (100%) cases showed diffuse and strong positivity for CD 45, and CD 20. Fourteen patients were immune competent while one was immune compromised. Conclusions: PCNSL often occurs in middle-aged and aged patients. There is female predilection especially in the middle age. Frontal region is the most common location with diffuse large B-cell lymphoma being the predominant subtype. PMID:27366250

    Undergraduate teaching in clinical laboratory medicine is at the center of contemporary medical education. Students are expected to learn advanced laboratory medicine and basic diagnostic skills such as blood sampling, peripheral blood cell counting, blood typing, cross match test, urinalysis, electrocardiography, and bacteriological examinations through their training program. In our department, we have compulsory lectures, a basic practical training course and an advanced training course for the medical students. The compulsory lectures are programmed for the students in the fourth grade to obtain basic knowledge of clinical laboratory medicine and the patho-physiology of diseases. The teaching staff makes every effort to make their lectures exciting and interesting. As we experienced as medical students in the past, boring lectures give students nothing but a nap. For every senior teaching staff in our school, it is obligatory to be evaluated on their lectures by the students and other teaching staff every year to improve their teaching skills and materials. Teaching materials utilizing personal computers and the Internet are becoming more and more important. The basic practical training course is for the students in the fifth grade. The laboratory technicians help us teach students basic diagnostic skills in this program. The students in the advanced training course have to attend morning conferences in the department, including reverse clinico-pathological conferences and laboratory investigations. The reversed clinico-pathological conferences are popular among the students. Through our training programs, we hope that the students raise many questions that they solve themselves in the future, as well as learning established clinical laboratory medicine.

    Keeping an updated registry of bleeding disorders is crucial for planning care and documenting prevalence. We aimed to assess the prevalence of various bleeding disorders including rare inherited coagulation and platelet disorders concerning their clinico-epidemiological, diagnostic data and bleeding manifestations severity. Patients suffering from manifestations of bleeding or coagulation disorders presented to Hematology Clinic during 16 years were included and prospectively followed up. Demographics, clinical characteristics, complete blood count, bleeding, prothrombin and activated partial thromboplastin times, platelet aggregation tests and bone marrow aspiration were recorded. Overall 687 patients with bleeding disorders from total 2949 patients were identified. Inherited coagulation defects were found in 27.2%; hemophilia A (70.6%), hemophilia B (13.9%), factor I deficiency (2.3%), factor V deficiency (1.6%), factor X deficiency (4.2%), factor VII deficiency (2.6%), factor XIII deficiency (1.1%), combined factor deficiency (2.1%) and unclassified coagulation disorders in 1.6% of studied patients. Overall 72.7% had diagnosed with platelet disorders; immune thrombocytopenia was the commonest (74.8%), and inherited conditions represent (25.2%) in the following order: Glanzman's thrombasthenia (11.2%), von Willebrand disease (6.6%), Bernard-Soulier syndrome (1%) and Chediak Higashi in 0.4% and unclassified in 6%. Median age of diagnosis of coagulation and platelet disorders were 33 and 72 months. Presenting symptoms of coagulation disorders were: 25.1% post circumcision bleeding, 22.5% ecchymosis, 20.9% hemoarthrosis and 15% epistaxis. Symptoms of rare coagulation disorders were postcircumcision bleeding (20%), bleeding umbilical stump (20%), epistaxis (12%), hemoarthrosis (8%) and hematomas (4%). Presenting symptoms in rare inherited platelet disorders were purpura, ecchymosis, epistaxis and bleeding gums, respectively. Analysis of the clinico

    Introduccion. Las convulsiones febriles son una de las causas mas frecuentes de consulta. Hasta ahora, los pacientes con convulsiones febriles complejas (CFC) deben ingresar, dado el mayor porcentaje de epilepsia y complicaciones agudas descrito clasicamente. En la actualidad hay estudios que apoyan ser menos invasivos en el abordaje de estos pacientes. Objetivo. Describir las caracteristicas de los pacientes ingresados por CFC y proponer un nuevo protocolo de actuacion. Pacientes y metodos. Analisis retrospectivo de historias clinicas de ingresados por CFC (enero de 2010-diciembre de 2013). Se ofrecen datos epidemiologicos, clinicos, pruebas complementarias y evolucion. Resultados. Las CFC suponian un 4,2% de los ingresos de neuropediatria (n = 67). Edad media al evento: 25 meses. El 47% tenia antecedentes familiares patologicos, y el 31%, antecedentes personales de convulsion febril previa. En el 54% de los pacientes, la CFC duro menos de cinco minutos; hubo recurrencia, la mayoria con un total de dos crisis y durante el primer dia (las CFC por recurrencia son las mas frecuentes). De las pruebas complementarias realizadas, ninguna de ellas sirvio como apoyo diagnostico en el momento agudo. Durante su seguimiento, cinco pacientes presentaron complicaciones. Los pacientes con antecedentes familiares de convulsiones febriles presentan mayor riesgo de epilepsia o recurrencia (p = 0,02), sin diferencias significativas respecto a la edad, numero de crisis, intervalo de fiebre, estado epileptico o tipo de CFC. Conclusiones. Las CFC no asocian mayores complicaciones agudas; las exploraciones complementarias no permiten discriminar precozmente a los pacientes de riesgo. Su ingreso podria evitarse en ausencia de otros signos clinicos y limitarse a casos seleccionados.

    Introduccion. El virus linfotropo humano de celulas T tipo 1 (HTLV-1) es el agente causal de la paraparesia espastica tropical. Su prevalencia, elevada en determinadas areas tropicales, es baja en Europa y Norteamerica. Casos clinicos. Se describen dos casos de paraparesia espastica tropical en varones naturales y residentes en Galicia. Se realizaron estudios analiticos en la sangre y el liquido cefalorraquideo (LCR), examenes neurofisiologicos y resonancia magnetica craneal y medular. En ambos pacientes, la presentacion clinica fue la de una mielopatia cronica, con cuadro torpido y progresivo que evoluciono a paraparesia espastica. Un paciente desarrollo uveitis antes de la clinica neurologica. En los dos casos, el estudio del LCR demostro leve pleocitosis linfoide, ligera hiperproteinorraquia, bandas oligoclonales negativas y anticuerpos anti-HTLV-1 positivos. La reaccion en cadena de la polimerasa para HTLV-1 resulto positiva en ambos casos. La resonancia magnetica raquidea resulto normal en un paciente y mostro en el otro hiperseñal medular dorsal, que desaparecio tras el tratamiento. No se demostraron datos de polineuropatia periferica. Recibieron corticoides e interferon alfa, con leve mejoria y estabilizacion del cuadro clinico. La anamnesis dirigida revelo antecedentes de contactos sexuales de riesgo en regiones endemicas de HTLV-1. Conclusiones. La uveitis asociada a HTLV-1 podria ser predictora de paraparesia espastica tropical. Esta es probablemente una entidad infradiagnosticada (alto porcentaje de portadores asintomaticos, clinica insidiosa y bajo indice de sospecha en areas no endemicas). Debe considerarse su diagnostico en zonas no tropicales que reciben inmigrantes de areas endemicas y tambien en regiones con una tradicional emigracion a regiones tropicales.

La deficiencia de MCT8, o sindrome de Allan-Herndon-Dudley, es un trastorno ligado a X que, generalmente, se presenta como un cuadro neurologico grave de inicio precoz, con un perfil tiroideo caracteristico (aumento de T3 y disminucion de T4 y rT3). Objetivo. Se presenta el primer caso diagnosticado en España con este sindrome y se revisa la bibliografia publicada, las distintas formas de presentacion clinica, los avances geneticos, el diagnostico diferencial y las perspectivas terapeuticas, y se propone un algoritmo diagnostico. Caso clinico. Varon de 5 años con un cuadro clinico compatible con una enfermedad de Pelizaeus-Merzbacher. La secuenciacion del gen PLP1 no mostro alteraciones. Todos los estudios metabolicos y geneticos realizados fueron normales. Finalmente, un estudio completo del perfil tiroideo revelo alteraciones compatibles con una deficiencia del transportador MCT8. La secuenciacion del gen SLC16A2 (MCT8) mostro una mutacion en el exon 3 y el estudio celular confirmo que esta mutacion cambia las propiedades de la proteina. Conclusiones. En los ultimos años se han multiplicado las publicaciones sobre este sindrome, con la identificacion de mas de 50 familias en el mundo. Es importante conocer este sindrome y sospecharlo, porque el diagnostico es facil, economico y accesible (perfil tiroideo), y, aunque no tiene tratamiento especifico, el diagnostico precoz evita pruebas innecesarias y permite ofrecer consejo genetico a las familias afectadas.

    Missense mutations of the GJA1 gene encoding the gap junction channel protein connexin43 (Cx43) cause bone malformations resulting in oculodentodigital dysplasia (ODDD), while GJA1 null and ODDD mutant mice develop osteopenia. In this study we investigated Cx43 expression and channel functions in giant cell tumor of bone (GCTB), a locally aggressive osteolytic lesion with uncertain progression. Cx43 protein levels assessed by immunohistochemistry were correlated with GCTB cell types, clinico-radiological stages and progression free survival in tissue microarrays of 89 primary and 34 recurrent GCTB cases. Cx43 expression, phosphorylation, subcellular distribution and gap junction coupling was also investigated and compared between cultured neoplastic GCTB stromal cells and bone marow stromal cells or HDFa fibroblasts as a control. In GCTB tissues, most Cx43 was produced by CD163 negative neoplastic stromal cells and less by CD163 positive reactive monocytes/macrophages or by giant cells. Significantly less Cx43 was detected in α-smooth muscle actin positive than α-smooth muscle actin negative stromal cells and in osteoclast-rich tumor nests than in the adjacent reactive stroma. Progressively reduced Cx43 production in GCTB was significantly linked to advanced clinico-radiological stages and worse progression free survival. In neoplastic GCTB stromal cell cultures most Cx43 protein was localized in the paranuclear-Golgi region, while it was concentrated in the cell membranes both in bone marrow stromal cells and HDFa fibroblasts. In Western blots, alkaline phosphatase sensitive bands, linked to serine residues (Ser369, Ser372 or Ser373) detected in control cells, were missing in GCTB stromal cells. Defective cell membrane localization of Cx43 channels was in line with the significantly reduced transfer of the 622 Da fluorescing calcein dye between GCTB stromal cells. Our results show that significant downregulation of Cx43 expression and gap junction coupling in

Analisis descriptivo de una serie de MAV operadas por un neurocirujano. Pacientes y metodos. De un registro hospitalario se han seleccionado los casos de MAV cerebrales operados por el autor en el periodo 1990-mayo 2014, revisando los aspectos clinicos, demograficos y angiograficos, y los resultados clinicorradiologicos seis meses despues de la cirugia. Resultados. De los 400 pacientes tratados en el mismo periodo, 121 fueron intervenidos por el autor, con una media de edad de 34,3 años (rango: 5-75 años). El 61,7% de los pacientes se diagnostico por una hemorragia cerebral, y la segunda forma de presentacion mas frecuente, el 19,8%, por crisis epilepticas. La localizacion superficial supratentorial, en 97 casos (80,2%), fue la mas frecuente. Mas de la mitad de los enfermos presentaba una MAV de grados bajos, I-II, segun la escala de Spetzler y Martin. Doce pacientes (10%) tenian aneurismas no intranidales asociados. En la mayoria de los casos, 109 (90,1%), se realizo cirugia electiva. La reseccion completa de la MAV despues del ultimo examen angiografico se obtuvo en 118 pacientes (97,5%). Los resultados clinicos fueron buenos (buena recuperacion y moderada incapacidad) en 114 casos (95%), y malos (gran incapacidad y muerte), en seis (5%). Conclusiones. La cirugia para las MAV cerebrales, con un criterio de seleccion apropiado, es la mejor opcion terapeutica para muchos pacientes.

Disminuyo en los pacientes con fracaso del inmunomodulador (el 85,6% el primer año, p < 0,0001; el 88,9% el segundo año, p = 0,0039) y aumento de forma no significativa en los pacientes VJC+ en el primer año. El porcentaje de pacientes libres de brotes en la poblacion global aumento del 32,6 al 68,1% en el primer año (p < 0,0019) y al 82,6% en el segundo (p = 0,0215). Este aumento no se observo en los pacientes VJC+. Trece pacientes tuvieron efectos secundarios, que obligaron a la retirada del farmaco en dos de ellos. Conclusion. En la practica clinica de la provincia de Alicante, el fingolimod mostro una efectividad y una seguridad ligeramente superiores a las de los ensayos clinicos.

    Introduccion. La estimulacion de nervios occipitales (ENO) es un tratamiento preventivo de la migraña cronica refractaria que esta adquiriendo una importancia creciente en los ultimos años. Objetivo. Evaluar el mecanismo de accion, estudios clinicos, tecnica de implantacion y criterios de inclusion de la ENO en el tratamiento preventivo de la migraña. Desarrollo. Se realiza una revision no sistematica de la bibliografia sobre los aspectos anteriormente expuestos en la ENO como tratamiento para la migraña cronica. Esta patologia afecta aproximadamente al 2% de la poblacion y da lugar a una importante disminucion de la calidad de vida e interferencia con las actividades laborales y sociales. La ENO es una terapia emergente y prometedora para el tratamiento de la migraña cronica que ha demostrado una disminucion superior al 50% en el dolor en la mayoria de los estudios abiertos y ensayos clinicos publicados. Aunque el mecanismo de accion es desconocido, parece existir una neuromodulacion de la informacion nociceptiva trigeminal en el nucleo caudal del trigemino explicada mediante la teoria de la puerta de entrada de Melzack y Wall. La ENO es un tratamiento seguro y bien tolerado, y los efectos secundarios son habitualmente locales, como desplazamiento de los electrodos o infecciones de la herida quirurgica, que habitualmente no requieren su retirada. Conclusiones. La ENO es un tratamiento eficaz, bien tolerado y seguro en la prevencion de la migraña cronica, y supone una opcion util para aquellos pacientes con migraña cronica refractaria a los tratamientos medicos convencionales.

    Introduccion. El sindrome de Charles Bonnet (SCB) es un cuadro clinico que se caracteriza por la presencia de alucinaciones visuales, principalmente complejas, en pacientes con estado cognitivo conservado e importante deterioro de la vision. El incremento del SCB se debe al aumento de la esperanza de vida y al desarrollo de patologias asociadas al envejecimiento, como la degeneracion macular asociada a la edad. Pacientes y metodos. Se estudian las caracteristicas de una serie de 45 pacientes diagnosticados de SCB en la unidad de neurooftalmologia del Hospital Clinico San Carlos. Los pacientes procedian de las unidades de patologia macular, glaucoma, superficie ocular y urgencias, en las que fueron diagnosticados de SCB, que se confirmo en la unidad multidisciplinar formada por oftalmologia, neurologia y psiquiatria del mismo hospital. Resultados. El 66,66% eran mujeres, de mas de 80 anos (68,88%), principalmente con degeneracion macular asociada a la edad (37,77%). Las alucinaciones que los pacientes presentaban con mas frecuencia eran personas y caras (35,55%), en color (66,66%), en movimiento (80%), con un tiempo de evolucion de 6-12 meses (26,66%), frecuencia de tres episodios al dia (35,55%) y de 3-5 minutos de duracion (35,55%). Conclusiones. El SCB es un complejo sindrome cuya incidencia se esta incrementando en nuestras consultas y que precisa un abordaje multidisciplinar entre oftalmologos, neurologos y psiquiatras para evitar diagnosticos erroneos y proporcionar un tratamiento adecuado. Son necesarios nuevos estudios para un conocimiento mas profundo y adecuado del SCB.

    Introduction A number of cases of Leishmaniasis have been reported from non-endemic sub-himalayan regions of India. Due to low clinical suspicion and atypical presentation, cases may go undetected or there may be a delay in diagnosis. Aim The aim of the study was to evaluate clinico-haematological parameters and bone marrow findings so that a high degree of suspicion could be made in unsuspected cases of Visceral Leishmaniasis (VL) and Leishman Donovan (LD) body negative bone marrow smears. Materials and Methods A retrospective study was conducted at a tertiary care centre serving the kumaon region of Uttarakhand from 2010 to 2014. Forty bone marrow aspirates were included, which were sent on clinical suspicion of VL. Twenty cases were positive for LD bodies. Their clinico-haematological features including bone marrow findings were studied in detail and compared with rest of the 20 LD negative cases. Five LD negative cases were also positive for rk39. Results Twenty LD positive cases were evaluated. Splenomegaly was the most common sign present in 17 cases (85%). Anaemia, leucopenia and lymphocytosis were present in all the cases (100%). Pancytopenia was seen in 17 cases (85%). Microcytic hypochromic blood picture was the most common finding in 11 cases (55%). Bone marrow was normocellular in 7 cases (35%), hypercellular in 7 cases (35%). Erythropoesis was micro-normoblastic in 11 cases (55%). Overall, there were 25 cases of VL (20 LD positive, 5 LD negative). Increased plasma cells, lymphocytes and histiocytes were seen in 17 cases (68%) of VL. Conclusion In non-endemic region where clinical suspicion is low, bone marrow findings can be a strong indicator for VL even though marrow is negative for LD bodies. If required other ancillary investigations can also be ordered. This study also emphasizes the need for epidemiological work up in this region. PMID:27437230

    Objetivo: La diabetes mellitus tipo 2 (DM2) es uno de los principales problemas sociosanitarios a nivel mundial, para la que existen multitud de tratamientos. Recientemente, se ha aprobado el primer farmaco de una nueva familia de antidiabeticos orales (ADO): la dapagliflozina. Nuestro objetivo es revisar la evidencia cientifica disponible sobre la dapagliflozina, con el fin de analizar su eficacia, seguridad y coste y poder estimar su papel en la farmacoterapia actual de la DM2. Métodos: La eficacia y seguridad de la dapagliflozina se analizaron mediante una evaluacion de la evidencia cientifica. El coste de los diferentes ADO se calculo en base a sus dosis diarias definidas (DDD) y al precio de venta del laboratorio. Resultados: Se identificaron 7 ensayos clinicos aleatorizados: 2 en monoterapia (840 pacientes) y 5 en terapia combinada con otros antidiabeticos (3184 pacientes). En los 7 ensayos, la dapagliflozina redujo la concentracion de HbA1c; en todos se comparo con placebo, salvo en un estudio en terapia combinada que se comparo frente a farmaco activo (glipizida). Entre los efectos adversos mas frecuentes se detectaron infecciones genitourinarias e hipotension, aunque se debe prestar especial atencion al incremento del cancer de vejiga. Junto con los inhibidores de la DPP-4, la dapagliflozina es uno de los ADO de mayor coste (coste anual de DDD=729,3 euros). Conclusiones: La dapagliflozina no aporta ventajas respecto a la farmacoterapia de la DM2 ya existente. Su falta de experiencia de uso, la ausencia de importantes beneficios clinicos y su elevado coste hacen necesario restringir su utilizacion.

    CDC25A, CDC25B and CDC25C belong to a family of protein phosphatases which activate the cyclin-dependent kinase at different points of the cell cycle. According to accumulating evidence, CDC25A and CDC25B seem to possess oncogenic properties. We have analysed these expressions by immunohistochemistry, western blot and RT-PCR in a series of 100 patients with squamous cell carcinoma of the oesophagus. When compared with non-cancerous cells, CDC25A and CDC25B were strongly expressed in the cytoplasm of cancer cells, with positive (+) classification in 46% (46 cases) and 48% (48 cases), respectively. There was no significant correlation between CDC25A and CDC25B expression, nor was there any association with the expression of other cell cycle-regulating molecules, including cyclin D1, Rb, p16INK4, p27KIP1 and PCNA (proliferating cell nuclear antigen). CDC25A (+), as well as CDC25B (+), was more frequently found in patients with deeper tumour invasion and lymph node metastasis, while tumour size was correlated only with CDC25A expression. Postoperative survival was significantly poorer for CDC25A (+) patients than CDC25A (–) patients, but was not affected by the CDC25B status. Nuclear localization of CDC25A was observed in 51 cases (51%), regardless of its cytoplasmic expression, and was not associated with clinico-pathological factors or prognosis. Multivariate analysis revealed only the CDC25A status to be an independent significant prognostic factor among these biological and clinico-pathological factors. CDC25A but not CDC25B may be a new prognostic factor for squamous cell carcinoma of the oesophagus. Thus, regulation of the G1 checkpoint in the cell cycle may be important in oesophageal carcinogenesis, which may also involve many other oncogenes. © 2001 Cancer Research Campaign http://www.bjcancer.com PMID:11487274

    Medulloblastoma, the most common primary pediatric malignant brain tumor is a molecularly heterogeneous disease with different developmental origins, distinct phenotypes, diverse biological behaviour, and contrasting clinical outcomes. The current clinico-radiological risk-classification fails to take account of this heterogeneity and existent prognostic variability. It is widely accepted that dysregulation of normal developmental processes constitute a key mechanism of tumorigenesis in at least a subset of medulloblastomas. Several attempts at biological classification have successfully identified distinct subgroups with subgroup-specific gene signatures, demographics, histologic subtypes, and rates of metastases. Several research groups have classified medulloblastoma into molecular subgroups using a variety of different genomic approaches and platforms such as gene expression profiling, microRNA profiling and methylation arrays. Recently, a consensus has emerged that classifies medulloblastoma into four distinct molecular subgroups named as wingless (WNT), sonic hedgehog (SHH), Group 3 and Group 4 respectively. However, such integrative approaches have limited applicability in the clinic due to the need of fresh-frozen tissues and elaborate molecular biology tools. In parallel, some groups have proposed and validated traditional antibody-based approaches using immunohistochemistry on archival specimen for rapid and reliable molecular subgrouping to be applied in any basic neuropathology laboratory. Heterogeneity within each of these four consensus subgroups has also been demonstrated that needs to be considered in the design of future clinical trials. There is a compelling need to integrate molecular biomarkers with clinico-pathologic outcome indicators to refine risk-stratification as well as develop novel molecularly targeted agents for optimizing therapeutic index and personalizing therapy.

  7. Monocarboxylate transporter 4 (MCT4) and CD147 overexpression is associated with poor prognosis in prostate cancer

    PubMed Central

    2011-01-01

    Background Monocarboxylate transporters (MCTs) are transmembrane proteins involved in the transport of monocarboxylates across the plasma membrane, which appear to play an important role in solid tumours, however the role of MCTs in prostate cancer is largely unknown. The aim of the present work was to evaluate the clinico-pathological value of monocarboxylate transporters (MCTs) expression, namely MCT1, MCT2 and MCT4, together with CD147 and gp70 as MCT1/4 and MCT2 chaperones, respectively, in prostate carcinoma. Methods Prostate tissues were obtained from 171 patients, who performed radical prostatectomy and 14 patients who performed cystoprostatectomy. Samples and clinico-pathological data were retrieved and organized into tissue microarray (TMAs) blocks. Protein expression was evaluated by immunohistochemistry in neoplastic (n = 171), adjacent non-neoplastic tissues (n = 135), PIN lesions (n = 40) and normal prostatic tissue (n = 14). Protein expression was correlated with patients' clinicopathologic characteristics. Results In the present study, a significant increase of MCT2 and MCT4 expression in the cytoplasm of tumour cells and a significant decrease in both MCT1 and CD147 expression in prostate tumour cells was observed when compared to normal tissue. All MCT isoforms and CD147 were expressed in PIN lesions. Importantly, for MCT2 and MCT4 the expression levels in PIN lesions were between normal and tumour tissue, which might indicate a role for these MCTs in the malignant transformation. Associations were found between MCT1, MCT4 and CD147 expressions and poor prognosis markers; importantly MCT4 and CD147 overexpression correlated with higher PSA levels, Gleason score and pT stage, as well as with perineural invasion and biochemical recurrence. Conclusions Our data provides novel evidence for the involvement of MCTs in prostate cancer. According to our results, we consider that MCT2 should be further explored as tumour marker and both MCT4 and CD147 as

    Nonmuscle invasive (NMI) urothelial cancer (UC) is associated with varied biological potential. It is characterized by frequent recurrence and progression, which thus worsens the oncological outcome. Nearly three-quarters of NMI UCs recur within 5 years, whereas half can progress during follow-up. Progression is particularly seen in T1 and carcinoma in situ (CIS). Undoubtedly, NMI UC is one of the most expensive cancers to manage. The European Organisation for Research and Treatment of Cancer (EORTC) risk calculator is a commonly used tool for assessing the recurrence and progression potential of a newly diagnosed cancer. The parameters used in the assessment are tumor size and number, pathological stage and grade of the cancer, presence of CIS, and prior recurrence rate. The main advantages of the EORTC tool are its ease of use and the lack of need to run expensive molecular tests. However, reproducibility of pathologic stage and grade is modest, which is a concern to clinicians. Molecular markers have potential for predicting the clinical outcome of NMI UC, given that clinico-pathologic variables are not sufficient for prediction of prognosis in an individual. Significant work has been done in the past 2 decades in understanding the molecular biology of bladder cancer; however, the translational value of this knowledge remains poor. The role for molecular markers in predicting recurrence seems limited because multifocal disease and incomplete treatment are probably more important for recurrence than the molecular features of a resected tumor. Urinary markers have very limited value in prognostication of bladder cancer and are used (mainly as an adjunct to cytology) for detection and surveillance of urothelial cell cancer recurrence. Prediction of progression with molecular markers holds considerable promise. Nevertheless, the contemporary value of molecular markers over clinico-pathologic indexes is limited. PMID:26279824

    Targeting the PD-1/PD-L1 immune checkpoint signaling is a novel promising treatment strategy in several tumor entities, and it is suggested that PD-L1/PD-1 expression is predictive for a PD-1/PD-L1 checkpoint inhibitor treatment response. We investigated the expression of PD-L1 and PD-1 by immunohistochemistry in a large and well characterized gastric cancer (GC) cohort of Caucasian patients, consisting of 465 GC samples and 15 corresponding liver metastases. Staining results were correlated with clinico-pathological characteristics and survival. PD-L1 expression was found in tumor cells of 140 GCs (30.1%) and 9 liver metastases (60%) respectively in immune cells of 411 GCs (88.4%) and 11 liver metastases (73.3%). PD-1 was expressed in tumor infiltrating lymphocytes in 250 GCs (53.8%) and in 11 liver metastases (73.3%). PD-L1 expression was significantly more prevalent in men, GCs of the proximal stomach, unclassified, papillary, Her2/neu-positive, Epstein-Barr-virus-positive, microsatellite instable, and PIK3CA-mutated GCs. A high PD-L1/PD-1 expression was associated with a significantly better patient outcome, and PD-L1 turned out to be an independent survival prognosticator. The correlation of PD-L1/PD-1 expression with distinct clinico-pathological patient characteristics may serve as a surrogate marker of PD-L1-positive GCs and may direct the use of immune checkpoint treatment strategies.

    Sommario INTRODUZIONE: L’ecografia dell’addome sta acquistando un ruolo sempre maggiore nell’iter diagnostico del dolore addominale, tuttavia il suo ruolo nella diagnosi di alcuni importanti quadri di dolore addominale è ancora in corso di studio. Scopo del nostro studio è stato valutare il ruolo dell’ecografia nella diagnosi differenziale di dolore addominale in un reparto di medicina interna. Materiali e metodi: Abbiamo condotto un’analisi retrospettiva di 248 ecografie addominali eseguite per dolore addominale nel nostro centro. Per ogni esame, sono stati registrati i dati inseriti nel modulo di richiesta e i reperti ecografici che potevano essere considerati correlati a dolore addominale. Risultati: In 105 pazienti (42%) l’ecografia dell’addome ha rilevato un reperto ecografico rilevante ed è stata quindi considerata positiva. Un’alta percentuale di pazienti era anziana (>65 anni, 52%) e grande anziana (>80 anni, 24%): questi soggetti avevano percentuale significativamente maggiore di esami ecografici positivi. La percentuale di indagini positive non è risultata significativamente diversa tra quelle eseguite per dolore addominale localizzato e non localizzato. Specifiche localizzazioni di dolore addominale erano associate a determinati reperti ecografici, come masse epatiche, masse ovariche e calcolosi renale, mentre dolore addominale non localizzato era associato a reperti ecografici di versamento liquido addominale e anse intestinali distese da fluido. DISCUSSIONE: Un’alta percentuale di indagini ecografiche ha identificato condizioni che potrebbero causare dolore addominale. Il valore diagnostico dell’ecografia addominale è stato maggiore in pazienti anziani e grandi anziani. Quando viene richiesta un’ecografia addominale, l’esame dovrebbe sempre essere valutato nell’ambito nel contesto clinico. Il clinico dovrebbe essere consapevole della grande potenzialità dell’ecografia addominale nella diagnosi delle diverse cause di

    Background Breast cancer in very young patients represents a unique issue that needs more attention as the number of cases is increasing and it has special characteristics at presentation, diagnosis, and biologic behaviors which reflect on both treatment strategies and survival. The aim of the current study was to analyze and report the clinico-pathological characteristics and treatment procedures used for breast cancer in very young patients over the last decade in a single Egyptian cancer center. Patients and methods A retrospective study was conducted in the Oncology Center – Mansoura University, where the data of all breast cancer patients, between September 2006 and August 2015, were reviewed. Among 4,628 patients who were diagnosed with breast cancer during this period, only 300 patients aged ≤35 years had complete registry data. Clinico-pathological characteristics, therapeutic procedures, and survival outcome were reported. Results Three hundred and seventy-nine patients (8.19%) were aged ≤35 years at the time of presentation. The age ranged between 21 and 35 years, and the mean age was 31 years (±3 standard deviation). Positive family history of breast cancer was found in 12.3%, and metastatic presentation was seen in 4.7%. The rate of axillary lymph nodes involvement was 75.7%. The estrogen receptor-negative disease was found in 51%, and among 217 patients who did HER2 test, 82 patients (37.8%) were HER2 positive, while triple-negative subtype was found in 57 patients (26.4%). Ki 67 percentage ranged between 3% and 66% (median was 35%). The median disease-free survival was 61 months (95% confidence interval 44–78 months); the 3-year and 5-year disease-free survival were 58% and 50%, respectively. The 3-year and 5-year overall survival were 88% and 68%, respectively. Conclusion Very young Egyptian patients with breast cancer should be given focus and specially studied as the presentation has more aggressive biologic behavior at advanced stages, so

    Background Differences in the incidence and outcome of breast cancer among Hispanic women compared with white women are well documented and are likely explained by ethnic differences in genetic composition, lifestyle, or environmental exposures. Methodolgy/Principal Findings A population-based study was conducted in Galicia, Spain. A total of 510 women diagnosed with operable invasive breast cancer between 1997 and 2010 participated in the study. Data on demographics, breast cancer risk factors, and clinico-pathological characteristics were collected. The different breast cancer tumor subtypes were compared on their clinico-pathological characteristics and risk factor profiles, particularly reproductive variables and breastfeeding. Among the 501 breast cancer patients (with known ER and PR receptors), 85% were ER+/PR+ and 15% were ER-&PR-. Among the 405 breast cancer with known ER, PR and HER2 status, 71% were ER+/PR+/HER2- (luminal A), 14% were ER+/PR+/HER2+ (luminal B), 10% were ER−/PR−/HER2- (triple negative breast cancer, TNBC), and 5% were ER−/PR−/HER2+ (non-luminal). A lifetime breastfeeding period equal to or longer than 7 months was less frequent in case patients with TNBC (OR = 0.25, 95% CI = 0.08–0.68) compared to luminal A breast cancers. Both a low (2 or fewer pregnancies) and a high (3–4 pregnancies) number of pregnancies combined with a long breastfeeding period were associated with reduced odds of TNBC compared with luminal A breast cancer, although the association seemed to be slightly more pronounced among women with a low number of pregnancies (OR = 0.09, 95% CI = 0.005–0.54). Conclusions/Significance In case-case analyses with the luminal A cases as the reference group, we observed a lower proportion of TNBC among women who breastfed 7 or more months. The combination of longer breastfeeding duration and lower parity seemed to further reduce the odds of having a TNBC compared to a luminal A breast cancer. PMID

    Background We aimed to study the pathogenic roles of High-Mobility Group Box 1 (HMGB1) / Receptor-for-Advanced-Glycation-End-products (RAGE) signaling and pro-inflammatory cytokines in patients with active pulmonary tuberculosis (PTB). Methods A prospective study was conducted among non-HIV adults newly-diagnosed with active PTB at two acute-care hospitals (n = 80); age-and-sex matched asymptomatic individuals (tested for latent TB) were used for comparison (n = 45). Plasma concentrations of 8 cytokines/chemokines, HMGB1, soluble-RAGE, and transmembrane-RAGE expressed on monocytes/dendritic cells, were measured. Gene expression (mRNA) of HMGB1, RAGE, and inflammasome-NALP3 was quantified. Patients’ PBMCs were stimulated with recombinant-HMGB1 and MTB-antigen (lipoarabinomannan) for cytokine induction ex vivo. Results In active PTB, plasma IL-8/CXCL8 [median(IQR), 6.0(3.6–15.1) vs 3.6(3.6–3.6) pg/ml, P<0.001] and IL-6 were elevated, which significantly correlated with mycobacterial load, extent of lung consolidation (rs +0.509, P<0.001), severity-score (rs +0.317, P = 0.004), and fever and hospitalization durations (rs +0.407, P<0.001). IL-18 and sTNFR1 also increased. Plasma IL-8/CXCL8 (adjusted OR 1.12, 95%CI 1.02–1.23 per unit increase, P = 0.021) and HMGB1 (adjusted OR 1.42 per unit increase, 95%CI 1.08–1.87, P = 0.012) concentrations were independent predictors for respiratory failure, as well as for ICU admission/death. Gene expression of HMGB1, RAGE, and inflammasome-NALP3 were upregulated (1.2−2.8 fold). Transmembrane-RAGE was increased, whereas the decoy soluble-RAGE was significantly depleted. RAGE and HMGB1 gene expressions positively correlated with cytokine levels (IL-8/CXCL8, IL-6, sTNFR1) and clinico-/radiographical severity (e.g. extent of consolidation rs +0.240, P = 0.034). Ex vivo, recombinant-HMGB1 potentiated cytokine release (e.g. TNF-α) when combined with lipoarabinomannan. Conclusion In patients with active PTB, HMGB1/RAGE

    Chronic internal inflammation secondary to adiposity is a risk factor for sporadic breast cancer and Post-Menopausal Breast Cancer (PMBC) is largely defined as such. Adiposity is one of the clinical criteria for the diagnosis of Metabolic Syndrome (MetS) and is a risk factor for PMBC. We examined SNPs of eight genes implicated in adiposity, inflammation and cell proliferation in a Prospective-specimen-collection, Retrospective-Blinded-Evaluation (PRoBE) design approach. A total of 180 cases and 732 age-matched controls were identified from the MyCode prospective biobank database and then linked to the Clinical Decision Information System, an enterprise-wide data warehouse, to retrieve clinico-demographic data. Samples were analyzed in a core laboratory where the personnel were masked to their status. Results from multivariate logistic regression yielded one SNP (rs2922126) in the GHSR as protective against PMBC among homozygotes for the minor allele (A/A) (OR = 0.4, 95% CI 0.18-.89, P-value = .02); homozygosity for the minor allele (C/C) of the SNP (rs889312) of the gene MAP3K1 was associated with the risk of PMBC (OR = 2.41, 95% CI 1.25-4.63 P-value = .008). Advanced age was protective against PMBC (OR = 0.98, 95% CI 0.95-0.99, P-value = .02). Family history of breast cancer (OR = 2.22, 95% CI 1.14-4.43. P = .02), HRT (OR = 3.35; 95% CI 2.15-5.21, P < .001), and MetS (OR = 14.83, 95% CI 5.63-39.08, P < .001) and interaction between HRT and MetS (OR = 39.38, 95% CI 15.71-98.70, P < .001) were associated with the risk of PMBC. We did not detected significant interactions between SNPs or between the SNPs and the clinico-demographic risk factors. Our study further confirms that MetS increases the risk of PMBC and argues in favor of reducing exposure to HRT. Our findings are another confirmation that low penetrance genes involved in the inflammatory pathway, i.e. MAP3KI gene, may have a plausible causative role in

    Background Lung cancer is the leading cause of cancer deaths in the world, and more and more treatment modalities have been introduced in order to improve patients’ survival. For patients with advanced non-small cell lung cancer (NSCLC), survival prognosis is poor and multimodality neoadjuvant therapies are given to improve patients’ survival. However, the possibility of occult metastases may lead to discrepancy between clinical and pathologic staging and underestimation of the disease severity. This discrepancy could be the reason for poor survival prediction reported by previous studies which conducted their analysis from the point of view of clinical stage. The aim of this study was to analyze the relationship between clinico-pathologic factors and survival from the pathologic point of view and to try to identify survival prognostic factors. Methods From January 2005 to June 2011, 88 patients received neoadjuvant therapy because of initial locally advanced disease, followed by anatomic resection and mediastinal lymph node (LN) dissection. All their clinico-pathologic data were collected from a retrospective review of the medical records and subjected to further analysis. Results We found that total metastatic LN ratio (P=0.01) and tumor size (P=0.02) were predictive factors for disease free survival (DFS). We used these two prognostic factors to stratify all patients into four groups. Group 4 (tumor size ≤5, total metastatic LN ratio ≤0.065) had the best DFS curve, while the DFS curve progressively deteriorated across group 3 (tumor size ≤5, total metastatic LN ratio >0.065), group 2 (tumor size >5, total metastatic LN ratio ≤0.065) and group 1 (tumor size >5, total metastatic LN ratio >0.065). However, no definitive prognostic factor could be identified in this study. Conclusions In conclusion, tumor size greater than 5 cm and total metastatic LN ratio greater than 0.065 could predict the DFS of patients with advanced NSCLC after multimodality

    Chronic internal inflammation secondary to adiposity is a risk factor for sporadic breast cancer and Post-Menopausal Breast Cancer (PMBC) is largely defined as such. Adiposity is one of the clinical criteria for the diagnosis of Metabolic Syndrome (MetS) and is a risk factor for PMBC. We examined SNPs of eight genes implicated in adiposity, inflammation and cell proliferation in a Prospective-specimen-collection, Retrospective-Blinded-Evaluation (PRoBE) design approach. A total of 180 cases and 732 age-matched controls were identified from the MyCode prospective biobank database and then linked to the Clinical Decision Information System, an enterprise-wide data warehouse, to retrieve clinico-demographic data. Samples were analyzed in a core laboratory where the personnel were masked to their status. Results from multivariate logistic regression yielded one SNP (rs2922126) in the GHSR as protective against PMBC among homozygotes for the minor allele (A/A) (OR = 0.4, 95% CI 0.18-.89, P-value = .02); homozygosity for the minor allele (C/C) of the SNP (rs889312) of the gene MAP3K1 was associated with the risk of PMBC (OR = 2.41, 95% CI 1.25-4.63 P-value = .008). Advanced age was protective against PMBC (OR = 0.98, 95% CI 0.95-0.99, P-value = .02). Family history of breast cancer (OR = 2.22, 95% CI 1.14-4.43. P = .02), HRT (OR = 3.35; 95% CI 2.15-5.21, P < .001), and MetS (OR = 14.83, 95% CI 5.63-39.08, P < .001) and interaction between HRT and MetS (OR = 39.38, 95% CI 15.71-98.70, P < .001) were associated with the risk of PMBC. We did not detected significant interactions between SNPs or between the SNPs and the clinico-demographic risk factors. Our study further confirms that MetS increases the risk of PMBC and argues in favor of reducing exposure to HRT. Our findings are another confirmation that low penetrance genes involved in the inflammatory pathway, i.e. MAP3KI gene, may have a plausible causative role in

    I feocromocitomi bilaterali sono rari; nella maggior parte dei casi presentano origine ereditaria e sono legati a mutazioni germinali relative ai geni RET, VHL o SDHx, tuttavia in altri casi non viene ritrovata alcuna eziologia. A tal proposito riportiamo il caso clinico di una donna di 76 anni, giunta alla nostra osservazione per malessere generale sopravvenuto in concomitanza di crisi ipertensive responsabili di ospedalizzazione. Il profilo ormonale realizzato in tale occasione, era suggestivo di feocromocitoma (metanefrine plasmatiche ed urinarie 10 volte superiori al range di normalità). Gli esami radiologici (TC e RMN) rivelavano due lesioni surrenaliche bilaterali di diametro rispettivamente a destra di 47 mm ed a sinistra di 26 mm. Mentre la TC definiva le dimensioni di queste lesioni, il loro carattere eterogeneo e la loro ipervascolarizzazione oltre ai rapporti con gli organi adiacenti, la RMN si esprimeva già in favore di feocromocitoma bilaterale. La scintigrafia alla MIBG mostrava una iperfissazione a carico della lesione surrenalica destra mentre sulla surrenale controlaterale evidenziava una fissazione limitata, relativa alla midollare normale. Tenuto conto del forte sospetto di feocromocitoma bilaterale, veniva eseguita una TEP alla 18F-FDOPA che mostrava un intenso ipermetabolismo a carico della massa surrenalica destra, mentre controlateralmente una fissazione simile a quella del fegato e pertanto non sospetta, nonostante molti studi sostengano una sensibilità uguale o addirittura superiore della TEP alla 18-FDOPA rispetto alla scintigrafia MIBG nei pazienti con feocromocitoma o paraganglioma. In un primo tempo veniva eseguita una surrenalectomia destra per via laparoscopica. In fase post-operatoria, in seguito alla constatazione del persistente incremento delle metanefrine plasmatiche ed urinarie, veniva realizzata una TEP alla 18 FDG che confermava la presenza di un’area di ipermetabolismo intenso a carico della lesione surrenalica sinistra

  18. Co-evolution of cancer microenvironment reveals distinctive patterns of gastric cancer invasion: laboratory evidence and clinical significance

    PubMed Central

    2010-01-01

    Background Cancer invasion results from constant interactions between cancer cells and their microenvironment. Major components of the cancer microenvironment are stromal cells, infiltrating inflammatory cells, collagens, matrix metalloproteinases (MMP) and newly formed blood vessels. This study was to determine the roles of MMP-9, MMP-2, type IV collagen, infiltrating macrophages and tumor microvessels in gastric cancer (GC) invasion and their clinico-pathological significance. Methods Paraffin-embedded tissue sections from 37 GC patients were studied by Streptavidin-Peroxidase (SP) immunohistochemical technique to determine the levels of MMP-2, MMP-9, type IV collagen, macrophages infiltration and microvessel density (MVD). Different invasion patterns were delineated and their correlation with major clinico-pathological information was explored. Results MMP2 expression was higher in malignant gland compared to normal gland, especially nearby the basement membrane (BM). High densities of macrophages at the interface of cancer nests and stroma were found where BM integrity was destroyed. MMP2 expression was significantly increased in cases with recurrence and distant metastasis (P = 0.047 and 0.048, respectively). Infiltrating macrophages were correlated with serosa invasion (P = 0.011) and TNM stage (P = 0.001). MVD was higher in type IV collagen negative group compared to type IV collagen positive group (P = 0.026). MVD was related to infiltrating macrophages density (P = 0.040). Patients with negative MMP9 expression had better overall survival (OS) compared to those with positive MMP9 expression (Median OS 44.0 vs 13.5 mo, P = 0.036). Median OS was significantly longer in type IV collagen positive group than negative group (Median OS 25.5 vs 10.0 mo, P = 0.044). The cumulative OS rate was higher in low macrophages density group than in high macrophages density group (median OS 40.5 vs 13.0 mo, P = 0.056). Median OS was significantly longer in low MVD group than

    The study was based on the frequent occurrence of intermittent slow waves right-posterior accentuation (IRP) in the EEGs of psychiatric patients. With regard to the EEG-phenomenon we present a detailed morphological and functional description as well as an evaluation from a developmental point of view. According to case histories a clinico-psychopathological characterization of the patients with IRP is given. The IRP-phenomenon can be interpreted electrogenetically against the background of and in connection with the so-called slow alpha variant rhythms as well as the posterior slow waves characteristic of children and adolescents. These patterns have in common a certain tendency to right-sided accentuation. In accord with a hypothesis (which has been derived from other observations and considerations) of a "maturation gradient" which favours the left hemisphere, we try to explain the IRP-phenomenon as an expression of a maturation deficit. Whereas the slow alpha variant rhythms and the posterior slow waves characteristic of children and adolescents appear bilaterally for the most part, IRP by definition, limited to the right hemisphere, may be considered as a less pronounced form in comparison. Deriving from clinico-psychopathological assessment the relationships are as follows: Patients with IRP account for about 5% of the in-patients in our psychiatric hospital. The IRP phenomenon seems to be closely linked to the male sex. Although a clear relationship with nosological categories (ICD) could not be proved, it seems that patients suffering from schizophrenic psychoses (ICD No. 295) are more frequently represented among the patients with the IRP-phenomenon than others. For the group of schizophrenic patients with IRP we found in contrast to a control group of schizophrenics without IRP a tendency to earlier onset of their disease. Compared with the control group it is found that the IRP groups consists of younger patients at the time of conducting this study. The

    Ellis-van Creveld syndrome is an autosomal recessive disorder mainly characterized by a disproportionate limb dwarfism, chondroectodermal dysplasia, congenital heart disease, postaxial polydactyly, and dysplastic fingernails and teeth. Only 300 cases have been published worldwide. We report a 21-week fetus with rhizomelia and polydactyly detected. Gross photographs, radiologic studies and pathological study were performed leading to the clinico-pathological suspicion of EvC. DNA from fresh fetal tissue was extracted for sequencing the EVC and EVC2 genes. p.W215X and p.R677X mutations were identified in the EVC2 gene in the fetal sample. Parental sample analysis showed the p.W215X mutation to be inherited from the mother and the p.R677X mutation from the father. The clinical information is essential not only to arrive at a correct diagnosis in fetuses with pathologic ultrasound findings, but also to offer a proper genetic counseling to the parents and their relatives.

    The endothelial hybridoma (EAhy926) cell line was employed to clarify whether antiphospholipid antibodies (aPA) [lupus anticoagulant (LA), antiprothrombin antibody (aPT) and/or anticardiolipin antibody (aCL)] and anti-endothelial cell antibodies (AECA) are identical, and establish whether beta2-glycoprotein I (beta2-GPI) is needed for reactivity of aPA to endothelial cells. Ig-G AECA was positive in 9/30 SLE patients with aPA (30.0%) and 10/22 SLE patients negative for aPA (45.5%). Ig-M AECA was positive in one SLE patient with aPA and one SLE patient without aPA. AECA-positivity was not significantly different among unfixed, TNF-stimulated and fixed EAhy926. The influence of beta2-GPI on the reactivity of serum to EAhy926 was minimal, and absorption experiments of serum with cardiolipin-liposome/beta2-GPI or phosphatidylserine-liposome/prothrombin gave little evidence of cross-reactivity of aPA and AECA. The results of our study suggest that aPA and AECA may have partially cross-reacted, but were different antibodies. However, further study is needed to clarify the clinico-pathological significance of AECA. PMID:9136970

  2. The value of simple microbiological studies for on-site screening of acute neonatal conjunctivitis in Angola

    PubMed Central

    2014-01-01

    Background Neonatal conjunctivitis or ophthalmia neonatorum (ON) is an acute bacterial conjunctivitis contracted by newborns during delivery. In non-industrialized countries, detection of the etiological agent is difficult due to the unavailability of modern diagnostic resources. Therefore, we analyzed the effectiveness of Gram and methylene blue staining techniques, which are simple microbiological methods in suspecting the aetiology of ON in a maternity ward in Luanda, Angola. Findings Neonatal conjunctival smears (n = 95), maternal data, and perinatal factors were collected. Slides were air-dried and sent to the Microbiology Department of the Hospital Clinico Universitario, Valladolid, Spain, where trained personnel performed Gram and methylene blue staining methods. Findings were interpreted by two expert microbiologists. Ophthalmological examination of all children showed five newborns with clinical signs of ON. Fourteen mothers reported were suspected with vulvo-vaginitis, and 27 had a urinary infection during pregnancy. Gram staining revealed the presence of epithelial cells in 87.6% and leukocytes in 15% of the conjunctival smears. These values were significantly higher than those shown by methylene blue staining. No rods, cocci, or yeasts were identified by either staining method. Chlamydia trachomatis DNA was also undetected in a small sub-sample with clinical suspicion of ON. There was no correlation among the presence of ON, ON microbes, maternal data, or perinatal factors. Conclusions Basic microbiological techniques did not provide enough information for screening cases of ON in Angola. Therefore, the use of molecular biology or other techniques is warranted for this purpose. PMID:24460893

    Abstract Medical disputes in China are historically poorly documented. In particular, autopsy-based evaluation and its impact on medical malpractice claims remain largely unstudied. This study aims to document autopsy findings and medical malpractice in one of the largest cities of China, Wuhan, located in Hubei Province. A total of 519 autopsies were performed by the Department of Forensic Medicine, Wuhan University School of Medicine, Wuhan, China, over a 10-year period between 2004 and 2013. Of these cases, 190 (36.6%) were associated with medical malpractice claims. Joint evaluation by forensic pathologists and clinicians confirmed that 97 (51.1%) of the 190 claims were approved medical malpractice cases. The percentage of approved malpractice cases increased with patient age and varied according to medical setting, physician specialty, and organ system. The clinico-pathological diagnostic discrepancy was significantly different among various physician specialties (P = 0.031) and organ systems (P = 0.000). Of those cases involved in malpractice claims, aortic dissection, coronary heart disease, and acute respiratory infection were most common. Association between incorrect diagnosis and malpractice was significant (P = 0.001). This is the first report on China's medical malpractice and findings at autopsy which reflects the current state of health care services in one of the biggest cities in China. PMID:26559306

El ejercicio fisico ha demostrado beneficio en la rehabilitacion fisica de estos pacientes, pero su impacto en la funcion cognitiva no ha sido tan estudiado. Objetivo. Revisar los estudios que han evaluado el impacto del ejercicio fisico, especificamente del entrenamiento en fuerza/resistencia, sobre la mejora cognitiva en estos pacientes. Pacientes y metodos. Se realizo una busqueda en CENTRAL, Medline e ISI Web of Knowledge de estudios llevados a cabo en pacientes con ictus en los que se intervino con ejercicio fisico y se evaluo la funcion cognitiva tras la intervencion. Resultados. Se identificaron cinco estudios (93 pacientes). Los estudios identificados muestran una gran heterogeneidad en los tests usados para evaluar la funcion cognitiva y en los protocolos de ejercicio, y apoyan el impacto positivo del entrenamiento aerobico en la mejora en la funcion cognitiva. Los dos ultimos estudios publicados (50 pacientes) han evaluado de manera especifica la combinacion de entrenamiento aerobico y de fuerza/resistencia. Estos estudios sugieren que añadir fuerza/resistencia mejoraria en mayor medida la funcion cognitiva en general y la funcion ejecutiva en particular. Conclusiones. La actividad fisica constituye una estrategia prometedora para mejorar las funciones cognitivas tras el ictus. Se necesitan ensayos clinicos de mayor tamaño muestral y con mayor homogeneidad, tanto en los protocolos de ejercicio como en los tests usados para la funcion cognitiva, que confirmen estos resultados.

  5. Palmar spiny keratoderma associated with type IV hyperlipoproteinemia.

    We report the case of a 35-year-old man with acquired palmar spiny keratoderma (SK) in association with type IV hyperlipoproteinemia. Cutaneous lesions appeared 11 years before with no history of any previous skin conditions, topical medication or systemic treatment with Vitamin A-derived drugs, x-irradiation, arsenic poisoning or prolonged sun exposure. Family aggregation for SK or other disorders of keratinization was ruled out. Blood chemistries demonstrated hypertriglyceridemia (422 mg/dl) and elevation in plasma concentration of the pre-beta fraction (VLDL) of lipoproteins pattern compatible with a type IV hyperlipoproteinemia. Family aggregation for this metabolic defect was then confirmed. The histologic hallmark of the 'spine' lesion was a compact column of hyperparakeratotic cells (columnar hyperparakeratosis) continuous with a hypogranular layer, without further evidence of dyskeratotic or vacuolated keratinocytes and inflammatory cells in the corresponding dermis. SK represents a well-definite entity which fulfills precise clinico-histologic criteria. However, three main questions are related to SK: differential diagnosis with porokeratosis on histologic examination (columnar hyperparakeratosis or hyperorthokeratosis alone in SK vs. cornoid lamella accompanied by remarkable dermoepidermal changes in porokeratosis); classificative scheme (proper nomenclature to avoid misleading and confounding names); and nosological arrangement (probably two subsets exist: hereditary or benign; and acquired, or idiopathic, which may be paraneoplastic in about 50% of the patients). To the best of our knowledge this is the first case reporting the association between SK and a metabolic impairment although the real connections linking these conditions are still unclear.

    Introduccion. Durante los ultimos años se han descrito diversos tipos de congelacion de la marcha (CDM), definidos fundamentalmente por su respuesta o no al tratamiento con levodopa. El fenomeno de la CDM en la enfermedad de Parkinson es de presentacion muy variable de unos pacientes a otros, con sustrato fisiopatologico diverso. En algunos pacientes, el aumento del estimulo dopaminergico no solo no mejora, sino que puede empeorar este problema. Casos clinicos. Se presentan dos pacientes con enfermedad de Parkinson que fueron evaluados en situacion off, on y supra-on. Para la evaluacion motora se utilizo la Unified Parkinson's Disease Rating Scale III (bilateral) y el tapping test en las extremidades inferiores, y se cuantificaron los episodios de CDM que presentaban los pacientes en las tres situaciones. Ambos pacientes sufrian episodios de CDM en situacion off que no mejoraban significativamente durante el on. Al aumentar el estimulo dopaminergico, en un intento de mejorar la respuesta motora, empeoraron significativamente los episodios de CDM, hasta el punto de imposibilitar la marcha por graves bloqueos. Conclusiones. Los episodios de CDM no siempre son una mera consecuencia de la acinesia o la rigidez. En la fisiopatologia de la CDM podrian intervenir estructuras que desbordan la sustancia negra y el deficit dopaminergico, lo cual podria explicar la falta de respuesta adecuada al tratamiento e incluso el empeoramiento por desequilibrio de los neurotransmisores, en relacion con la sobreestimulacion dopaminergica, en otros nucleos implicados en el control postural y de la marcha.

    After about three decades, Chikungunya infection has re-emerged in India and the first cases were reported in December, 2005. The outbreak has currently affected about 8 states in the country. Although known to be commonly non fatal, since the present outbreak involved a large population, it has been raised as an issue of public health concern and also attracted wide media attention. The clinico-epidemiological and entomological review of the Chikungunya outbreak situation in Hyderabad and Nalgonda Districts of Andhra Pradesh, which started in December 2005, revealed that it is under control. However, preventive efforts need to continue and disease surveillance for early detection of potential outbreaks further strengthening. Given the significantly high House Index, all the three study areas remain at significant risk of outbreaks in the future if appropriate control measures are not put in place. Community support and participation is also crucial for the prevention of future outbreaks and improving the health and well being of population in the districts. PMID:21475442

    The constellation of clinico-pathological and laboratory findings including massive hepatomegaly, steatosis, and marked hypertriglyceridemia in infancy is extremely rare. We describe a child who is presented with the above findings, and despite extensive diagnostic testing no cause could be identified. Whole exome sequencing was performed on the patient and parents' DNA. Mutations in GPD1 encoding glycerol-3-phosphate dehydrogenase that catalyzes the reversible redox reaction of dihydroxyacetone phosphate and NADH to glycerol-3-phosphate (G3P) and NAD(+) were identified. The proband inherited a GPD1 deletion from the father determined using copy number analysis and a missense change p.(R229Q) from the mother. GPD1 protein was absent in the patient's liver biopsy on western blot. Low normal activity of carnitine palmitoyl transferases, CPT1 and CPT2, was present in the patient's skin fibroblasts, without mutations in genes encoding for these proteins. This is the first report of compound heterozygous mutations in GPD1 associated with a lack of GPD1 protein and reduction in CPT1 and CPT2 activity.

    Databases pertaining to various diseases provide valuable resources on particular genes of interest but lack the molecular subtype and epithelial-mesenchymal transition status. CSIOVDB is a transcriptomic microarray database of 3,431 human ovarian cancers, including carcinoma of the ovary, fallopian tube, and peritoneum, and metastasis to the ovary. The database also comprises stroma and ovarian surface epithelium from normal ovary tissue, as well as over 400 early-stage ovarian cancers. This unique database presents the molecular subtype and epithelial-mesenchymal transition status for each ovarian cancer sample, with major ovarian cancer histologies (clear cell, endometrioid, mucinous, low-grade serous, serous) represented. Clinico-pathological parameters available include tumor grade, surgical debulking status, clinical response and age. The database has 1,868 and 1,516 samples with information pertaining to overall and disease-free survival rates, respectively. The database also provides integration with the copy number, DNA methylation and mutation data from TCGA. CSIOVDB seeks to provide a resource for biomarker and therapeutic target exploration for ovarian cancer research. PMID:26549805

    The objective was to evaluate foodborne outbreaks of undetermined aetiology by comparing them to pathogen-specific epidemiologic profiles of laboratory-confirmed foodborne outbreaks. National foodborne outbreak data reported to CDC during 1982-9 were categorized by clinico-epidemiologic profiles based on incubation, duration, percent vomiting, fever and vomiting to fever ratio. From the pathogen-specific profiles, five syndromes were developed: a vomiting-toxin syndrome resembling Bacillus cereus and Staphylococcus aureus; a diarrhoea-toxin syndrome characteristic of Clostridium perfringens, a diarrhaeogenic Escherichia coli syndrome, a Norwalk-like virus syndrome, and a salmonella like syndrome. Of 712 outbreaks, 624 (87.6%) matched one of five syndromes; 340 (47.8%) matched the Norwalk-like syndrome and 83 (11.7%) matched the salmonella-like syndrome. After combining information on known pathogens and epidemiologic profiles, only 88 (12.4%) outbreaks remained unclassified. Norwalk-like virus outbreaks appear as common as salmonella-like outbreaks. We conclude that profiling can help classify outbreaks, guide investigations and direct laboratory testing to help detect new and emerging pathogens. PMID:11811869

    From a series of 5000 cases that had undergone extracorporeal shock wave lithotripsy at the Hospital Clinico Quirúrgico "Hermanos Ameijeiras" from March, 1986 to April, 1988, 220 cases that required percutaneous nephrostomy due to obstructive hydronephrosis from stone fragments were studied. We analyzed the clinical, radiological and ultrasound features of these cases, as well as the criteria for performing percutaneous nephrostomy. We identified the risk factors that made the procedure necessary, particularly urinary tract infection. No important complications ascribable to the foregoing procedure were observed. Performing the procedure early improved patient clinical course and reduced cost of treatment. To eliminate stone fragments completely, percutaneous nephrostomy was combined with other procedures in 198 cases (90%). The stone fragments were passed spontaneously in 10 cases (4.5%) following diversion. At 2 months 190 cases (86%) were completely stone free, 18 (8%) had residual stones and 12 (6%) required open surgery. The foregoing results show that percutaneous nephrostomy is a very useful procedure in septic-obstructive complications following extracorporeal shock wave lithotripsy and acquiring the skill to perform it is essential.

    Introduccion. La gastrosquisis es una malformacion de la pared abdominal que se corrige mediante cirugia y requiere cuidados hospitalarios especiales, como inmovilizacion, restriccion alimenticia y separacion de la madre durante tiempo variable, entre otros; para analizar las posibles repercusiones cognitivas se aplico la prueba de Bayley III a 14 niños. Sujetos y metodos. Siete casos (nacidos con gastrosquisis) y siete controles, en los hospitales civiles de Guadalajara, en el periodo enero-abril de 2013. Resultados. Los casos no evidenciaron retraso en las evaluaciones relacionadas con la cognicion, el lenguaje y la conducta motora, en tanto que en las asociadas a la conducta socioemocional y adaptativa las puntuaciones favorecieron al grupo control, lo que refleja que poseen mejores estrategias de adaptacion e interaccion respecto al grupo de casos. Conclusiones. La gastrosquisis no afectara el neurodesarrollo ulterior, por lo menos en este grupo que presento esta unica anormalidad y deficits explicables por sus circunstancias perinatales, sin que este pronostico pueda generalizarse a otros casos con un cuadro clinico mas grave, mayor duracion de la estancia hospitalaria y comorbilidad asociada. De cualquier forma, es importante informar a los padres desde la etapa prenatal respecto a las consecuencias esperadas de esta patologia.

    Introduccion. Los angioleiomiomas intracraneales son lesiones muy poco frecuentes. Solo se han descrito 22 casos en la bibliografia hasta la actualidad, unicamente tres de ellos de localizacion infratentorial. Caso clinico. Varon de 43 años con un angioleiomioma infratentorial descubierto de forma incidental tras la realizacion de una tomografia computarizada por hipoacusia. La resonancia magnetica mostro una tumoracion de 1,4 cm, descrita inicialmente como un meningioma, con un realce progresivo tras la administracion de gadolinio, un aumento del coeficiente de difusion aparente y un descenso generalizado de metabolitos en la espectroscopia. La lesion se reseco quirurgicamente mediante un abordaje suboccipital con buena evolucion y sin complicaciones postoperatorias. En el estudio histologico, la lesion presentaba un abundante componente vascular, y en la tincion inmunohistoquimica era positiva para actina y caldesmona. Dos años despues de la cirugia, el paciente no presentaba recurrencia en la resonancia magnetica de control. Conclusion. El diagnostico de los angioleiomiomas puede ser complejo, pero algunas de sus caracteristicas radiologicas pueden facilitarlo. Los angioleiomiomas son tumores benignos asociados con un resultado funcional favorable tras su reseccion completa, que en nuestro caso no presento un alto riesgo de sangrado.

    Diabetes mellitus type 2 is a metabolic disorder characterized by high blood glucose due to insulin deficiency or resistance. Alzheimer's disease (AD) is a complex neurodegenerative disease leading to irreversible loss of neurons, intellectual abilities, memory and reasoning. The worldwide prevalence of diabetes and AD in elderly population is a major public health concern. Interestingly, both health issues are unraveling the puzzling links. The clinico-pathological relationship between diabetes and AD has been reported at genomic and proteomic levels. The association of virus infection in type 2 diabetes mellitus and AD has been reported in few recent studies, some have shown direct evidence of virus infection in diabetes and AD while other have shown that diabetes increases the risk of developing AD. This review aims to summarize the association of few common viruses like Hepatitis C Virus and Herpes Simplex Virus-1 which affects both these two age-related devastating diseases. We also discuss the pathological links of Influenza virus, Cytomegalovirus, West Nile virus, Enterovirus, Herpes Simplex Virus-2, Hepatitis viruses in diabetes and Influenza virus, Picornavirus and Borna disease virus in AD. Establishing such relationships and defining their common pathogenesis and patho-physiological mechanisms may lead to new concepts and paths for developing novel preventive strategies and pharmacological treatment options for diabetes and AD. This study may aid in future for the identification of a single or a panel of likely blood-based viral biomarkers for early diagnosis of diabetes and AD with high sensitivity and specificity.

    Osteoblastoma (OB) is an uncommon benign bone-forming tumor accounting for <1% of all bone neoplasms. Unlike conventional OB, its small subset variant “Epithelioid osteoblastoma (EO)” is characterized by its propensity for local invasion and recurrent behavior. This rare variant of an uncommon tumor when occurs in an atypical site can lead to diagnostic problems more so due to ambiguous clinico-radiologic presentation. This was what faced in the present case of 18-year-old female with a swelling in upper jaw. OB is usually more common in males and involves primarily the posterior element of the spine and the sacrum (40–55%). Less frequently, long bones of limbs are involved. Clinical, radiological and histopathological correlation in this case guided us to reach at right diagnosis of EO which helped the patient in getting correct treatment which involves surgical excision over conventional curettage. The purpose behind this case presentation is to improve the awareness about this recurrent tumor variant which has many close differentials including well-differentiated osteoblastic osteosarcoma.

    RIASSUNTO. Lo scopo del presente studio è quello di esplorare le proprietà psicometriche di uno strumento di misurazione dell'affetto, la Scala di Esperienze Positive e Negative (SPANE), all'interno di una popolazione italiana. Gli esiti dell'analisi fattoriale confermativa comprovano l'attesa struttura a due fattori, sentimenti positivi e negativi. Le correlazioni con altre dimensioni (per es., ansia, depressione, affetto, aspettative future) confermano i risultati ottenuti con le precedenti versioni della scala: affetto negativo, ansia, depressione e aspettative future negative correlano positivamente con la subscala di esperienze negative e negativamente con la subscala di esperienze positive dello SPANE. In conclusione, i risultati del nostro studio dimostrano che la versione italiana dello SPANE presenta caratteristiche psicometriche simili a quelle mostrate dalla versione orginale e da successive validazioni dello strumento in altre lingue. La scala presenta, inoltre, affidabilità e validità fattoriale. Lo SPANE è un indice utile dal punto di vista clinico che può fornire informazioni rilevanti circa l'esperienza emotiva e il benessere della persona. Nonostante ulteriori studi siano necessari per confermare le caratteristiche psicometriche della scala, la presente validazione della versione italiana dello SPANE può contribuire ad ampliare la ricerca nell'ambito del benessere in una popolazione Italiana.

    The aqueous extract from Leonotis leonurus (L) R.Br. (Lamiaceae) shoots was evaluated in female rats for its acute, sub acute, and chronic toxicity together with hematological, biochemical, and histopathological changes. In the acute toxicity test, the extract caused death in animals receiving 3200 mg/kg dose. The extract also caused significant (P < 0.05) changes in red blood cells, packed cell volume, hemoglobin concentration, mean corpuscular volume, platelets, white blood cells and its differentials at doses of 1600 mg/kg in sub-acute toxicity and in as low as 200 mg/kg in chronic toxicity. In biochemical parameters, the extract caused a significant (P < 0.05) decrease in the levels of urea and creatinine at 1600 mg/kg dose and a significant (P < 0.05) reduction in urea, total bilirubin, total protein, albumin, globulin, glutamine transference gamma-glutamyl transferase (GGT), and alanine transminase in the 400 mg/kg dose in chronic toxicity. Changes were also noted in body weights, but no significant changes were observed in the levels of electrolytes (sodium, potassium, and chloride). Clinico-pathologically, starry hair coat, respiratory distress, and mortality were recorded. The extract also caused various histopathological changes in the organs. The study concluded that farmers need to exercise caution in the use of the plant for medicinal purposes. PMID:19244291

    The diagnosis of infectious bacterial neonatal syndrome (IBNS) was based on 3 arguments: --the suggestive anamnestic investigation of the mother; --clinical signs revealing the infection in the new-born child; --paraclinical data. The evoking anamnestic data during pregnancy and parturition are highly important. Of them, the most frequently met were: premature rupture of the membranes, modified amniotic liquid; with or without premature rupture of the membranes, urinary infections declared but not sufficiently treated, fever and pseudoinfluenza syndrome in the last term of the pregnancy etc. The clinical signs revealing the infection in the new-born are: disturbance in the behaviour and the proper clinical signs. Of the clinical data the authors followed the evolution of the hematologic data, the inflammatory test--serologic and bacteriologic (the greatest importance was given to the blood cultures and seeding in CSF). Therefore, IBNS transmitted through the mother-fetal route can be suspected only in the presence of conclusive anamnestic data. The clinical aspects, sometimes minor, corroborating the clinical evolution and the paraclinical data are of the greatest importance for the physician's decision. The clinical diagnosis based on serious clinico-anamnestic arguments should not be ignored by negative bacteriologic tests.

    L’appendicite acuta rappresenta la più comune patologia infiammatoria della cavità adddominale. Mc Burney ne ha per primo descritto il trattamento chirurgico utilizzando la classica incisione nel quadrante addominale inferiore destro. Tale approccio è stato considerato il trattamento standard della patologia appendicolare per più di un secolo, fino all’inizio dell’era video laparoscopica. I rapidi cambiamenti tecnici e gli innegabili vantaggi della procedura videolaparoscopica ha portato ad una ampia diffusione della metodica in ambito clinico. La chiusura del moncone appendicolare, durante l’appendicectomia video laparoscopica, rappresenta uno degli aspetti tecnici fondamentali della procedura per le gravi potenziali complicanze che possono derivare da un suo non appropriato trattamento. Gravi complicanze sono infatti rappresentate da deiscenza, fistole stercoracee e peritonite. La chiusura con endostapler, hem-o-look e legatura intracorporea rappresentano le metodiche più comunemente utilizzate. Tutte le alternative descritte presentano vantaggi e svantaggi e vanno rapportate ai diversi stadi clinici della patologia appendicolare. Va inoltre notato che le differenti metodiche di trattamento del moncone appendicolare non sono state testate in studi randomizzati. In base alla nostra esperienza si può affermare che il trattamento del moncone appendicolare con endoloop può essere utilizzato con sicurezza e dovrebbe essere considerata la metodica di scelta anche in relazione al rapporto costo-beneficio. Metodi alternativi di chiusura del moncone appendicolare andrebbero utilizzati in caso di appendicite flemmonosa o gangrenosa, ascesso peritiflitico e/o contemporaneo trattamento di diverticolo di Meckel.

    Introduccion. La neuralgia del trigemino es uno de los sindromes de dolor facial mas graves. La incidencia anual varia entre el 4-13% y altera de forma significativa la calidad de vida de los afectados. Cuando el dolor no puede controlarse con tratamiento farmacologico, existen diferentes opciones quirurgicas. La seleccion de la tecnica esta basada en estudios observacionales y su aplicacion depende de la experiencia de cada centro. Objetivos. Evaluar la efectividad y el nivel de evidencia del tratamiento farmacologico y quirurgico en la neuralgia del trigemino, y analizar el papel actual de las tecnicas percutaneas en el tratamiento de esta patologia. Desarrollo. El tratamiento inicial de la neuralgia del trigemino es el farmacologico y la carbamacepina es el unico farmaco con suficiente nivel de evidencia. Las tecnicas quirurgicas percutaneas son efectivas y de facil aplicacion, pero la tendencia a la recidiva conduce a la preferencia por la microdescompresion vascular. Sin embargo, no hay estudios comparativos que determinen la superioridad de alguna tecnica con buen nivel de evidencia. Se han revisado las tres tecnicas percutaneas mas utilizadas, la compresion con balon, la rizotomia con glicerol y la termocoagulacion por radiofrecuencia. Esta ultima es la que ha presentado mayor desarrollo en los ultimos años, con la aparicion de tecnicas neurofisiologicas que pueden optimizar los resultados. Conclusiones. La seleccion de una tecnica quirurgica en la neuralgia del trigemino no esta bien apoyada por ensayos clinicos aleatorizados. Los nuevos procedimientos en la aplicacion de la radiofrecuencia pueden mejorar las perspectivas del tratamiento de esta patologia.

    Databases pertaining to various diseases provide valuable resources on particular genes of interest but lack the molecular subtype and epithelial-mesenchymal transition status. CSIOVDB is a transcriptomic microarray database of 3,431 human ovarian cancers, including carcinoma of the ovary, fallopian tube, and peritoneum, and metastasis to the ovary. The database also comprises stroma and ovarian surface epithelium from normal ovary tissue, as well as over 400 early-stage ovarian cancers. This unique database presents the molecular subtype and epithelial-mesenchymal transition status for each ovarian cancer sample, with major ovarian cancer histologies (clear cell, endometrioid, mucinous, low-grade serous, serous) represented. Clinico-pathological parameters available include tumor grade, surgical debulking status, clinical response and age. The database has 1,868 and 1,516 samples with information pertaining to overall and disease-free survival rates, respectively. The database also provides integration with the copy number, DNA methylation and mutation data from TCGA. CSIOVDB seeks to provide a resource for biomarker and therapeutic target exploration for ovarian cancer research.

    We characterized the clinico-neurophysiological features of epileptic spasms, particularly focusing on high-voltage slow waves during ictal EEG. We studied 22 patients with epileptic spasms recorded during digital video-scalp EEG, including five individuals who still had persistent spasms after callosotomy. We analysed the duration, amplitude, latency to onset of electromyographic bursts, and distribution of the highest positive and negative peaks of slow waves in 352 spasms. High-voltage positive slow waves preceded the identifiable muscle contractions of spasms. The mean duration of these positive waves was 569±228 m, and the mean latency to electromyographic onset was 182±127 m. These parameters varied markedly even within a patient. The highest peak of the positive component was distributed in variable regions, which was not consistent with the location of lesions on MRI. The peak of the negative component following the positivity was distributed in the neighbouring or opposite areas of the positive peak distribution. No changes were evident in the pre- or post-surgical distributions of the positive peak, or in the interhemispheric delay between both hemispheres, in individuals with callosotomy. Our data imply that ictal positive slow waves are the most common EEG changes during spasms associated with a massive motor component. Plausible explanations for these widespread positive slow waves include the notion that EEG changes possibly reflect involvement of both cortical and subcortical structures.

    The objective was to determine the relationship between the mother's nutritional status and the newborn's gestational characteristics. A sample of 149 women with gestational diabetes was controlled in the High Risk Obstetric Unit of the Medical Specialties Public Health Center before delivery in the maternity ward of the Hospital Clinico Herminda Martín de Chillán, Chile in 2010. Data were obtained from the perinatal clinical history and the newborn's chart. The variables recorded for the mother were nutritional status, type of delivery, number of pregnancies, and metabolic control. Data for the newborn were weight, length, head circumference, and gestational diagnosis. These data were analyzed by ANOVA, Chi-square test, and Multiple Correspondence. Women with a normal nutritional status were multiparous with natural childbirth; the newborn had an adequate gestational age and normal head circumference. On the other hand, maternal obesity was related to a Cesarean; the newborn was large for gestational age and had a larger head circumference. Overweight women were primiparous and the newborn was small for gestational age with a smaller head circumference (p < 0.01). It was concluded that obesity in women with gestational diabetes explains variables such as type of delivery, number of gestations, and the newborn's diagnosis.

    Ever since the discovery of the first indigenous case in 1981, paragonimiasis has gained recognition as a significant food borne parasitic zoonosis in India. The data available on the occurrence of paragonimiasis, until today, may be just the tip of an iceberg as the study areas covered were restricted to Northeast Indian States. Nevertheless, the results of research on paragonimiasis in India have revealed valuable information in epidemiology, life cycle, pathobiology and speciation of Indian Paragonimus. Potamiscus manipurensis, Alcomon superciliosum and Maydelliathelphusa lugubris were identified as the crab hosts of Paragonimus. Paragonimus miyazakii manipurinus n. sub sp., P. hueit’ungensis, P. skrjabini, P. heterotremus, P. compactus, and P. westermani have been described from India. P. heterotremus was found as the causative agent of human paragonimiasis. Ingestion of undercooked crabs and raw crab extract was the major mode of infection. Pulmonary paragonimiasis was the commonest clinical manifestation while pleural effusion and subcutaneous nodules were the common extra-pulmonary forms. Clinico-radiological features of pulmonary paragonimiasis simulated pulmonary tuberculosis. Intradermal test, ELISA and Dot-immunogold filtration assay (DIGFA) were used for diagnosis and epidemiological survey of paragonimiasis. Phylogenitically, Indian Paragonimus species, although nested within the respective clade were distantly related to others within the clade. PMID:22960885

    Objective: To determine whether the preoperative lymphocyte-monocyte ratio (LMR) is a predictor of suboptimal cytoreduction in advanced-stage epithelial ovarian cancer (EOC). Methods: Preoperative clinico-pathologic and hematologic parameters were reviewed in a total of 154 patients with EOC submitted to primary cytoreductive surgery. Patients were categorized into two different groups according to the results of cytoreductive surgery: optimal and suboptimal cytoreduction. Continuous variables were categorized into two groups using the best cutoff points selected on the receiver operating characteristic (ROC) curve for suboptimal cytoreduction. Results: Based on data collected from the 154 patients, 133 (86.4%) and 21 (13.6%) patients presented with stage III and IV disease, respectively. One hundred seventeen (76.0%) patients had serous adenocarcinoma, and 92 (59.7%) had histologic tumor grade 3. The optimal and suboptimal cytoreduction groups included 96 (62.3%) and 58 patients (37.7%), respectively. The best LMR cutoff point for suboptimal cytoreduction was 3.75. On multivariate logistic regression analysis, age, cancer antigen 125, white blood cell count, and LMR were found to be the strongest predictors for suboptimal cytoreduction (P=0.0037, 0.0249, 0.0062, and 0.0015, respectively). Conclusion: Preoperative LMR is an independent predictor of suboptimal cytoreduction. It provides additional prognostic information beyond the biological parameters of the tumor. PMID:27698915

    Cerebrospinal fluid (CSF) concentrations of YKL-40 that serve as biomarker of neuroinflammation are known to be altered along the clinico-biological continuum of Alzheimer's disease (AD). The specific structural cerebral correlates of CSF YKL-40 were evaluated across the early stages of AD from normal to preclinical to mild dementia. Nonlinear gray matter (GM) volume associations with CSF YKL-40 levels were assessed in a total of 116 subjects, including normal controls and those with preclinical AD as defined by CSF Aβ < 500 pg/mL, mild cognitive impairment (MCI) due to AD, or mild AD dementia. Age-corrected YKL-40 levels were increased in MCIs versus the rest of groups and showed an inverse u-shaped association with p-tau values. A similar nonlinear relationship was found between GM volume and YKL-40 in inferior and lateral temporal regions spreading to the supramarginal gyrus, insula, inferior frontal cortex, and cerebellum in MCI and AD. These findings for YKL-40 remained unchanged after adjusting for p-tau, which was found to be associated with GM volumes in distinct anatomic areas. CSF YKL-40, a biomarker of glial inflammation, is associated with a cerebral structural signature distinct from that related to p-tau neurodegeneration at the earliest stages of cognitive decline due to AD.

Ademas, un ECA de buena calidad metodologica mostro que la educacion al paciente activo vias neurales inhibitorias descendentes del dolor. El analisis cualitativo muestra evidencia fuerte-moderada acerca de que la educacion al paciente, en combinacion con otras intervenciones de ejercicio terapeutico, ofrece resultados positivos en las variables de dolor, calidad de vida y funcionalidad. Conclusiones. La educacion al paciente por si sola no ha mostrado ser efectiva sobre el dolor, la calidad de vida ni la funcionalidad en pacientes con fibromialgia. Existe evidencia fuerte de la efectividad de la combinacion de educacion al paciente con ejercicio y estrategias activas de afrontamiento sobre el dolor, la calidad de vida y la funcionalidad a corto, medio y largo plazo en pacientes con fibromialgia.

    Clinico-instrumental criteria to reliably detect simulated vertigo remain to be defined. Computed dynamic posturography (Equitest) has been used to identify additional factors to distinguish simulated, from real vertigo. The present study population comprised 23 normal subjects and 16 patients with documented vestibular impairment. Normal subjects were also studied during a state of simulated vertigo. In malingerers, the Equilibrium Score and the Composite Equilibrium Score showed a statistically significant reduction in all test conditions as compared to normal subjects, patients and "non-malingerers". Upon Sensory Analysis, statistically significant differences were found for the somatosensory component between malingerers and "non-malingerers". In 20/23 cases, Strategy Score values recorded in malingerers were 2 Standard Deviations lower than the mean obtained in "non-malingerers" in at least one of the six test conditions. By combining the latter observation with Goebel's 1st criterion it was possible to differentiate malingerers from non-malingerers with 86.9% sensitivity and 89.7% specificity. The Equitest, therefore, in combination with conventional methods, provides the clinician with an important tool, in the identification of a state of simulated vertigo. PMID:15270427

    Pancytopenia is not a disease but an important clinico-haematological entity encountered in our day-to-day clinical practice with findings that may result from a number of disease processes. A total of 100 patients of pancytopenia admitted in medicine wards of Civil Hospital, Ahmedabad, Gujuarat, India, were studied. The most common cause of pancytopenia was megaloblastic anaemia (45%) followed by infections (20%) and hypersplenism (15%). As compared with other causes, megaloblastic anaemia was statistically significant cause (P < 0.01) of pancytopenia, in our study. The most common clinical presentation of patients with megaloblastic anaemia was lethargy (100%) and pallor (100%). In patients with megaloblastic anaemia, mean haemoglobin (Hb) was 5.6 ± 1.7 g/dl, mean white blood corpuscle (WBC) count was 2735 ± 4152 and mean platelet count was 52,250 ± 24,213. Mean corpuscular volume (MCV) was 101.2 ± 11 in patients of megaloblastic anaemia. Morphology of RBC was marocytic in 95% of patients with megaloblastic anaemia, whereas hypersegmented neutrophils and macrovalocytes were seen in 60-65% patients of megaloblastic anaemia.

    Introduccion. El dolor neuropatico es una entidad que no se conoce bien. Afecta a un porcentaje significativo de la poblacion. Su principal problema radica en que puede llegar a ser una patologia bastante invalidante. El tratamiento principal se basa fundamentalmente en dos farmacos: gabapentina y pregabalina. Otros farmacos, como los antidepresivos, los opioides o los antagonistas de receptores de N-metil D-aspartato tambien pueden utilizarse en combinacion con los farmacos principales. A pesar de esto, el tratamiento es poco satisfactorio. Ademas, debe considerarse que pueden existir pacientes que presenten alergia a los dos farmacos principales. Caso clinico. Mujer de 36 años, afecta de dolor neuropatico secundario a una cirugia de neurinoma del plexo braquial, cuyo tratamiento con gabapentina o pregabalina no era posible por tener antecedentes personales de alergia. Sin embargo, el tratamiento con otro farmaco (lacosamida) resulto muy efectivo, al presentar muy buena respuesta. Conclusion. La lacosamida es un farmaco antiepileptico de tercera generacion, eficaz, seguro y con pocos efectos secundarios. Se ha considerado una buena opcion terapeutica para el tratamiento del dolor neuropatico en pacientes alergicos a la pregabalina.

    Objective Giant cell tumor of bone (GCTB) is a locally aggressive primary bone tumor. Its malignant counterpart is quite rare. Rarely, a conventional GCTB shows marked nuclear atypia, referred to as symplastic/pseudoanaplastic change, which can mimic sarcomatous transformation. Recently, somatic driver mutations of histone H3.3 exclusively in H3F3A have been described in GCTB. We report a series of 9 cases of GCTB with symplastic/pseudoanaplastic change, along with analysis of H3F3A variants. Materials and methods Nine cases of GCTB with symplastic change were identified. Clinico-radiological features, morphological features, and immunohistochemical stain for Ki-67 stain were reviewed. H3F3A variants were also analyzed using Sanger sequencing. Results Histologically, conventional giant cell tumor areas with scattered foci of markedly atypical cells were seen in all of the cases and all showed rare if any Ki-67 labeling. One patient had received denosumab treatment and another radiation therapy. Radiological features were characteristic of conventional GCTB. Mutation in H3F3A (p.Gly34Trp [G34W]) was found in 6 of the 7 cases. Clinical follow-up ranged from 6 to 208 months. Local recurrences were seen in 4 cases (44 %). Conclusions GCTB with symplastic/pseudoanaplastic change is an uncommon variant of conventional GCTB, which can mimic primary sarcoma or sarcomatous transformation. These tumors possess the same missense mutation in histone H3.3 as conventional GCTB. PMID:27020452

    Vitamin D toxicity also known as hypervitaminosis D was previously believed to be rare. But with an increase in vitamin D supplementation several cases have been reported in literature. Fat soluble vitamins like Vitamin D, due to their ability to accumulate in the body, have a higher potential for toxicity than water soluble vitamins. The main clinical consequence of vitamin D toxicity is hypercalcemia. In this report we describe an adult female patient who developed very high serum Vitamin D levels (746 ng/mL, RI: 20 to 50) as a result of medication error. Inspite of such high serum concentrations the patient was without any clinical symptoms and had normal serum calcium. We critically discuss the mechanism of toxicity and hypothesize the possible molecular/metabolic factors which might have been responsible for this nontoxic presentation. This case study highlights the fact that physicians need to consider the risk of medication errors while prescribing Vitamin D therapy. Clinical trials to study Vitamin D toxicity in humans is not possible ethically. Thus the evidence base regarding the safety profile of Vitamin D supplementation in humans has been build through case reports. This review of the paradoxical clinico-laboratory manifestation of hypervitaminosis D could possibly contribute to existing literature. PMID:25918194

    Ovarian cancer is the most common cause of death among women with gynecologic cancer. We examined molecular profiles of fibroblasts from normal ovary and high-grade serous ovarian tumors to identify novel therapeutic targets involved in tumor progression. We identified 2,300 genes that are significantly differentially expressed in tumor-associated fibroblasts. Fibroblast expression of one of these genes, connective tissue growth factor (CTGF), was confirmed by immunohistochemistry. CTGF protein expression in ovarian tumor fibroblasts significantly correlated with gene expression levels. CTGF is a secreted component of the tumor microenvironment and is being pursued as a therapeutic target in pancreatic cancer. We examined its effect in in vitro and ex vivo ovarian cancer models, and examined associations between CTGF expression and clinico-pathologic characteristics in patients. CTGF promotes migration and peritoneal adhesion of ovarian cancer cells. These effects are abrogated by FG-3019, a human monoclonal antibody against CTGF, currently under clinical investigation as a therapeutic agent. Immunohistochemical analyses of high-grade serous ovarian tumors reveal that the highest level of tumor stromal CTGF expression was correlated with the poorest prognosis. Our findings identify CTGF as a promoter of peritoneal adhesion, likely to mediate metastasis, and a potential therapeutic target in high-grade serous ovarian cancer. These results warrant further studies into the therapeutic efficacy of FG-3019 in high-grade serous ovarian cancer. PMID:26575166

    Ovarian cancer is the most common cause of death among women with gynecologic cancer. We examined molecular profiles of fibroblasts from normal ovary and high-grade serous ovarian tumors to identify novel therapeutic targets involved in tumor progression. We identified 2,300 genes that are significantly differentially expressed in tumor-associated fibroblasts. Fibroblast expression of one of these genes, connective tissue growth factor (CTGF), was confirmed by immunohistochemistry. CTGF protein expression in ovarian tumor fibroblasts significantly correlated with gene expression levels. CTGF is a secreted component of the tumor microenvironment and is being pursued as a therapeutic target in pancreatic cancer. We examined its effect in in vitro and ex vivo ovarian cancer models, and examined associations between CTGF expression and clinico-pathologic characteristics in patients. CTGF promotes migration and peritoneal adhesion of ovarian cancer cells. These effects are abrogated by FG-3019, a human monoclonal antibody against CTGF, currently under clinical investigation as a therapeutic agent.

    SQLE encodes squalene epoxidase, a key enzyme in cholesterol synthesis. SQLE has sporadically been reported among copy-number driven transcripts in multi-omics cancer projects. Yet, its functional relevance has never been subjected to systematic analyses. Here, we assessed the correlation of SQLE copy number (CN) and gene expression (GE) across multiple cancer types, focusing on the clinico-pathological associations in breast cancer (BC). We then investigated whether any biological effect of SQLE inhibition could be observed in BC cell line models. Breast, ovarian, and colorectal cancers showed the highest CN driven GE among 8,783 cases from 22 cancer types, with BC presenting the strongest one. SQLE overexpression was more prevalent in aggressive BC, and was an independent prognostic factor of unfavorable outcome. Through SQLE pharmacological inhibition and silencing in a panel of BC cell lines portraying the diversity of SQLE CN and GE, we demonstrated that SQLE inhibition resulted in a copy-dosage correlated decrease in cell viability, and in a noticeable increase in replication time, only in lines with detectable SQLE transcript. Altogether, our results pinpoint SQLE as a bona fide metabolic oncogene by amplification, and as a therapeutic target in BC. These findings could have implications in other cancer types.

    2012-01-01

    During the last decade, gene expression profiling of breast cancer has revealed the existence of five molecular subtypes and allowed the establishment of a new classification. The basal subtype, which represents 15-25% of cases, is characterized by an expression profile similar to that of myoepithelial normal mammary cells. Basal tumors are frequently assimilated to triple-negative (TN) breast cancers. They display epidemiological and clinico-pathological features distinct from other subtypes. Their pattern of relapse is characterized by frequent and early relapses and visceral locations. Despite a relative sensitivity to chemotherapy, the prognosis is poor. Recent characterization of their molecular features, such as the dysfunction of the BRCA1 pathway or the frequent expression of EGFR, provides opportunities for optimizing the systemic treatment. Several clinical trials dedicated to basal or TN tumors are testing cytotoxic agents and/or molecularly targeted therapies. This review summarizes the current state of knowledge of this aggressive and hard-to-treat subtype of breast cancer. PMID:22082486

    Classic polyarteritis nodosa (PAN) that targets medium-sized muscular arteries and microscopic polyangiitis (MPA), characterized by inflammation of small-caliber vessels and the presence of circulating myeloperoxidase anti-neutrophil cytoplasmic antibodies (MPO-ANCA), are distinct clinicopathological entities of systemic vasculitis. A 66-year-old woman presented with fever, cholestasis and positive MPO-ANCA. Radiological examination showed a pancreatic mass compressing the bile duct. Therefore, we performed pancreatoduodenectomy. Histopathological examination revealed that necrotizing vasculitis predominantly affecting the medium-sized vessels, spared arterioles or capillaries in the pancreas, a finding consistent with PAN. Unexpectedly, renal biopsy revealed small-caliber vasculitis and glomerulonephritis, supporting MPA. The initial manifestation of a pancreatic mass associated with vasculitis has only been reported in 7 articles. Its diagnosis is challenging because no reliable clinico-radiological findings have been observed. Clinicians should be aware of such cases and early diagnosis followed by immunosuppression is mandatory. Our findings may reflect a polyangiitis overlap syndrome coexisting between pancreatic PAN and renal MPA.

    Laparoscopic colposacropexy has become a substitute for open surgery in the treatment of pelvic organ prolapse. In the same way, robotic assisted surgery is a new step in the evolution of the procedure. In this paper we intend to show our surgical technique and preliminary results. From November 2006 to date, 10 patients have undergone this procedure at the Hospital Clinico San Carlos. The main indication for the operation was existence of symptomatic pelvic prolapse. Both patients with or without hysterectomy have been operated, without making significant differences between them. Preoperative evaluation workout included: cystogram, urinary tract ultrasound and urodynamics in all cases; urinary tract MRI was performed only in selected cases. All patients underwent surgery under general anesthesia, with at least three robotic trocars (8 mm) and one conventional trocar for the assistant; 2 accessory trocars were necessary in some cases, mainly at the beginning of the series. Most procedures in our series were associated with a transobturator suburethral sling for the treatment of stress urinary incontinence or prevention of its appearance after prolapse repair. Our results are comparable to those reported in other larger series in terms of operative time, hospital stay and early or late complications. Pending an evaluation on the long term with larger series, we can include robot assisted colposacropexy among the therapeutic options for symptomatic pelvic floor prolapse repair.

    Introduccion. Las alucinaciones musicales son un tipo de alucinacion auditiva prevalente en la poblacion no psiquiatrica, pero escasamente comunicada en la bibliografia neurologica. Ocurren con mayor frecuencia en la poblacion anciana, del sexo femenino y con perdida de audicion, pero su fisiopatologia esta por desentrañar. Casos clinicos. Se presentan seis casos (cinco mujeres y un hombre) de alucinaciones musicales diagnosticados en una consulta de neurologia general en un lapso de tiempo de cinco años. En cinco de ellos concurria la hipoacusia en mayor o menor grado y uno estaba desencadenado por la pentoxifilina. En su mayoria, el contenido musical de las alucinaciones provenia de experiencias musicales vividas en la infancia y juventud. En los casos sometidos a tratamiento farmacologico la respuesta fue pobre; sin embargo, una vez explicada a los pacientes la benignidad del cuadro y su desvinculacion con patologia psicotica, el grado de aceptacion del sintoma fue bueno. Conclusiones. Las alucinaciones musicales son una patologia fronteriza entre la neurologia, la otorrinolaringologia y la psiquiatria poco conocida, que, con frecuencia, se vincula erroneamente a la enfermedad mental. Es fundamental explicar a pacientes y familiares el caracter no necesariamente psiquiatrico de este sintoma, asi como conocer la potencialidad que tienen algunos farmacos de uso comun para generarlo.

    Introduccion. Los gangliogliomas son tumores raros que afectan a pacientes jovenes, aparecen predominantemente en el lobulo temporal y suelen comenzar con crisis epilepticas. Histologicamente corresponden a un grado I de malignidad, con una forma anaplasica catalogada como de grado III en la clasificacion de la Organizacion Mundial de la Salud (OMS) de 2007. Sin embargo, existen tumores que no cumplen criterios de uno u otro grado y que presentan claras diferencias pronosticas respecto a los de grado I. Estos tumores corresponderian a gangliogliomas atipicos (grado II), no contemplados en la citada clasificacion. Desde el punto de vista molecular, la alteracion mas conocida en los gangliogliomas es la mutacion de BRAF V600E, que confiere peor pronostico a la lesion. La posibilidad de utilizar tratamientos dirigidos a esta proteina mutada otorga una especial relevancia a esta alteracion. Caso clinico. Varon de 21 años, intervenido de un ganglioglioma en dos ocasiones, en el que el examen neuropatologico objetivo caracteristicas histologicas compatibles con un grado de malignidad intermedio (grado II) con mutacion positiva a BRAF. Conclusiones. El caso presentado, junto con los descritos previamente en la bibliografia, reabre las controversias sobre la definicion de los gangliogliomas en la clasificacion de la OMS de 2007, y apoya el hecho de que la proxima clasificacion de la OMS deberia volver a incluir los gangliogliomas atipicos (grado II) e integrar posibles mutaciones geneticas y alteraciones moleculares.

    Background: Periorbital hyperpigmentation (POH) is a common hyperpigmentary problem of the face, which can be psychologically distressing and it can influence an individual's quality of life. However, this condition has received less attention in literature. Aims and Objectives: To study the clinico-etiological features and the effect of two therapeutic modalities on the quality of life in patients of POH before and after treatment. Materials and Methods: Fifty patients attending the outpatient clinic of Dermatology Department, with clinically evident POH were included. All patients were divided randomly into two groups of 25 each and one group was treated with 4% hydroquinone and another group with 30% salicylic acid for 12 weeks. Assessment with visual analog scale (VAS) was done at 4, 6, and 12 weeks, and outcome of the patients was analyzed statistically. Results: Majority of the cases, i.e. 26 (52%) were in the age group of 20–30 years. Females comprised 74% of the study population. On VAS, most of the patients showed mild improvement (10–30%) at 12 weeks of treatment in both the groups. Separately, both the treatments significantly improved the dermatological life quality index of the patients although there was no significant difference found between the two groups. Conclusion: POH is less responsive to standard treatments due to its multifactorial etiology and deposition of melanin in both dermis and epidermis. However, even the mild to moderate improvement in appearance can cause an improvement in the quality of life of the patients. PMID:27512187

    Objective The aim of this study was to evaluate renal arteriosclerotic lesions in patients with lupus nephritis and investigate their associations with clinical and pathological characteristics, especially cardio-vascular features. Design A retrospective cohort study. Participants Seventy-nine patients with renal biopsy-proven lupus nephritis, diagnosed between January 2000 and June 2008 from Peking University First Hospital. Results In clinico-pathological data, patients with arteriosclerosis had higher ratio of hypertension and more severe renal injury indices compared with patients with no renal vascular lesions. More importantly, patients with renal arteriosclerosis had worse cardiac structure and function under transthoracic echocardiographic examination. Patients with renal arteriosclerosis tend to have higher ratios of combined endpoints compared with those of no renal vascular lesions, although the difference didn’t reach statistical meanings (P = 0.104). Conclusion Renal arteriosclerotic lesion was common and associated with vascular immune complex deposits in lupus nephritis. It might have a certain degree of association with poor outcomes and cardiovascular events, which needs further explorations. PMID:26544865

    Introduccion. Durante el nacimiento, ocurren cambios fisiologicos en practicamente todos los organos del niño, incluyendo el sistema nervioso central. En esta fase de transicion, es posible un cierto grado de hipoxemia, en general bien tolerado por el neonato. Sin embargo, si la hipoxia neonatal es muy intensa y continuada, puede instalarse una encefalopatia neonatal, lo que caracteriza una situacion critica para el recien nacido. Su abordaje adecuado es imprescindible para garantizar un buen pronostico a largo plazo. Desarrollo. Se actualizan las informaciones acerca de la hipoxia neonatal y se revisan publicaciones recientes acerca de los avances en su abordaje a traves de la medicina basada en evidencias. Conclusiones. La encefalopatia neonatal se puede clasificar desde el punto de vista clinico en tres niveles de intensidad. Usualmente, los casos leves tienen un buen pronostico, los casos de intensidad moderada tienen un 30% de posibilidad de secuelas y los de intensidad grave tienen mas del 70% de mortalidad, pero practicamente todos los supervivientes tendran secuelas. Los avances ocurrieron en dos areas: en el diagnostico, con nuevas tecnicas de EEG y RM, y en el tratamiento, con la aparicion de la hipotermia terapeutica. Existe la posibilidad de un uso futuro para la terapia con celulas madre. El pronostico depende de la clasificacion clinica, de los datos de neuroimagen y del EEG.

La enfermedad celiaca es una enteropatia inducida por el gluten por mecanismos inmunes, que puede presentar afectacion sistemica y producir un amplio espectro de manifestaciones neurologicas, que van desde polineuropatia periferica, ataxia, epilepsia y migraña hasta encefalitis. El objetivo es informar de un caso de posible encefalitis refractaria por enfermedad celiaca. Caso clinico. Varon de 45 años con diagnostico histopatologico de enfermedad celiaca y anticuerpos anticeliaquia negativos que intercurre con encefalitis, manifestaciones del tronco encefalico y del sistema nervioso periferico, entre las que se incluyen deterioro cognitivo y convulsiones, diplopia y ataxia, y polirradiculopatia y polineuropatia, respectivamente; liquido cefalorraquideo inflamatorio y multiples lesiones corticosubcorticales supratentoriales y en el tronco encefalico con leve realce con contraste. Los deficits neurologicos progresan a pesar de una dieta libre de gluten y el tratamiento farmacologico inmunosupresor. Durante el curso de la enfermedad se estudian patologias con afectacion simultanea intestinal y del sistema nervioso, como sarcoidosis, lupus eritematoso sistemico, enfermedad de Sjogren, sindrome paraneoplasico, sida, enfermedad de Whipple y deficit de vitamina B12. Conclusion. La encefalitis es una manifestacion clinica infrecuente en la enfermedad celiaca, con pocos casos notificados a pesar de la alta prevalencia de la enfermedad. Los diagnosticos diferenciales son dificiles y exigen una alta sospecha diagnostica, por lo que es un reto terapeutico.

  5. Diagnosis and classification of juvenile idiopathic arthritis.

    2014-01-01

    In recent years, it has become increasingly clear that the term Juvenile Idiopathic Arthritis (JIA) comprises not one disease but several. Moreover, recent studies strongly suggest that some of these clinico-pathophysiologic entities appear to cross current diagnostic categories. The ultimate goal of the JIA classification is to facilitate development of better, more specific therapy for different forms of disease though improved understanding of pathophysiology. The past two decades have witnessed significant advances in treatment and improved outcomes for many children with chronic arthritis. However, understanding of the basic biologic processes underlying these diseases remains far from complete. As a result, even the best biologic agents of today represent "halfway technologies". Because they do not treat fundamental biologic processes, they are inherently expensive, need to be given for a long time in order to ameliorate the adverse effects of chronic inflammation, and do not cure the disease. Pediatric rheumatology is now entering an era in which diagnostic categories may need to change to keep up with discovery. A more precise, biologically based classification is likely to contribute to development of more specific and improved treatments for the various forms of childhood arthritis. In this review, we discuss how genetic, gene expression, and immunologic findings have begun to influence how these diseases are understood and classified.

    Dis-regulation of MAL (myelin and lymphocyte protein) has been implicated in several malignancies including esophageal, ovarian, and cervical cancers. The MAL protein functions in apical transport in polarized-epithelial cells, therefore its disruption may lead to loss of organized polarity characteristic of most solid malignancies. Bisulfite sequencing of the MAL promoter CpG island revealed hypermethylation in breast cancer cell lines and 69% of primary tumors analyzed compared to normal breast epithelial cells. Differential methylation between normal and cancer DNA was confined to the proximal promoter region. In a subset of breast cancer cell lines including T47D and MCF7 cells, promoter methylation correlated with transcriptional silencing that was reversible with the methylation inhibitor 5-Aza-2'-deoxycytidine. In addition, expression of MAL reduced motility and resulted in a redistribution of lipid raft components in MCF10A cells. MAL protein expression measured by immunohistochemistry revealed no significant correlation with clinico-pathologic features. However, in patients who did not receive adjuvant chemotherapy, reduced MAL expression was a significant predictive factor for disease-free survival. These data implicate MAL as a commonly altered gene in breast cancer with implications for response to chemotherapy. PMID:19208741

    Solitary fibrous tumor (SFT) is a neoplasm that can occur in the urogenital tract, and is also reported occurring in the spermatic cord, seminal vesicles, urinary bladder, prostate, and kidney. Furthermore, it is most important to consider its existence in the kidney, because it is usually diagnosed as renal cell carcinoma pre-operatively. To our knowledge, only 10 cases of SFT have been reported in the kidney to date. We report the clinico-pathological features of an intrarenal SFT occurring in a 31-year-old woman. The tumor, measuring 8.6 cm in its greatest diameter, completely replaced the cortex and the medulla of the middle region of the right kidney, compressing the pelvis. Radiological imaging was consistent with a renal cell carcinoma. Histologically, the tumor was composed of a proliferation of bland-looking vimentin+, CD34+, bcl2+ and CD99+ spindle cells exhibiting a haphazard to storiform growth pattern, pushing borders, and a low mitotic rate (2 mitoses x 10 HPF). We placed emphasis on the differential diagnostic problems, i.e., its differentiation from other primary monomorphous benign and malignant spindle cell tumors of the kidney, such as fibroma, benign fibrous histiocytoma, hemangiopericytoma, inflammatory myofibroblastic (pseudo-)tumor, leiomyoma, angiomyolipoma with predominant spindle cell smooth muscle component, benign peripheral nerve sheath tumors, renal mixed epithelial/stromal tumors, adult type mesoblastic nephroma, fibrous type monophasic synovial sarcoma, malignant peripheral nerve sheath tumors, fibrosarcoma, and low-grade fibromyxoid sarcoma.

    2012-01-01

    The nosology, classification and pathophysiology of ophthalmoplegic migraine (OM) remains complex and debatable. A recently proposed classification of OM leaves several caveats. A critical analysis of all reported cases of OM (1993–2010) has been made incorporating the authors’ own experience to arrive at a simple, unambiguous and easy to use diagnostic criteria and classification of OM. Between 2005 and 2010, 18 adult cases of OM had been seen whose clinical details are summarized. Most had sixth nerve palsies associated with migraine-like headaches lasting more than 4 days. Other possibilities were carefully excluded. All subjects responded to corticosteroids favorably. We prefer using the term ophthalmoplegia with migraine-like headache (OMLH) rather than OM. We classify OMLH as a migraine subtype (1.7) and into two groups—childhood-onset type (where third nerve palsies and nerve enhancement are common) and adult-onset type (where sixth nerve palsies are more common and nerve enhancement unusual). This clinico-radiological classification does not in any way hint at any difference in pathophysiology between the two groups. PMID:23024560

    To evaluate the clinico-pathological and survival characteristics in patients with bone metastasis. This cross-sectional study was conducted on patients with bone metastasis who referred to Shahid Ramezanzadeh radiation oncology center. For all of the patients studied, demographic and survival information was recorded. SPSS was used to analyze the data. In this study, 89 men (53.3%) and 78 women (46.7%) with bone metastasis were examined. Most of the patients were in the 66 to 87 age range. Breast cancer was the most common type of cancer in women and prostate cancer was the commonest in men. In most patients, pain was the first manifestation of the disease, and the spine has been most frequently involved areas. The disease was diagnosed by isotope bone scan in the most cases. The mean survival was 31.1 months for patients with breast cancer, 12.9 months for patients with prostate cancer, 13.7 months for patients with lung cancer and the overall survival was 22.5. There was only a meaningful correlation between sex, type of cancer, radiation dose, and survival in patients. We found that age was more effective than the variable of cancer type in survival of patients with bone metastasis. The prognosis of patients with bone metastasis in our center is fair. There was a significant correlation between sex, type of cancer, radiation dose, and survival. Cox proportional hazards model showed that age was a predictor of death.

    Existing reports on the frequencies of neurodegenerative diseases are typically based on clinical diagnoses. We sought to determine these frequencies in a prospectively-assessed, community-based autopsy series. Included subjects had normal cognitive and movement disorder assessments at study entry. Of the 119 cases meeting these criteria, 52% were female, median age of study entry was 83.5 years (range 67 to 99), and median duration from first visit until death was 4.3 years (range 0-10). At autopsy a clinico-neuropathological diagnosis was made in 30 cases (25%). Clinicopathological diagnoses included 20 (17%) with Alzheimer's disease (AD), 7 (6%) with vascular dementia, 4 (3%) with progressive supranuclear palsy, (1; 0.8%) with dementia with Lewy bodies, (1; 0.8%) with corticobasal degeneration and (1; 0.8%) with multiple system atrophy. Of those 87 subjects (73%) still clinically normal at death, 33 (38%) had extensive AD pathology (pre-clinical AD), 17 (20%) had incidental Lewy bodies and 4 (5%) had incidental pathology consistent with progressive supranuclear palsy. Diagnoses are not mutually exclusive. Although limited by a relatively small sample size, the neuropathological outcome of these initially normal elderly subjects represents a rough estimate of the incidence of these neurodegenerative conditions over a defined time period.

El sindrome de Pallister-Killian se caracteriza por discapacidad intelectual, hipotonia, retraso motor y un fenotipo caracteristico en el que destaca un aspecto facial tosco, alteraciones pigmentarias de la piel y alopecia bitemporal. Es frecuente que se asocie a crisis convulsivas y a malformaciones en otros organos y sistemas. Tiene como causa principal el mosaicismo para la tetrasomia del cromosoma 12p. Casos clinicos. Se presentan tres nuevos casos pediatricos afectos de esta rara entidad, se describen las caracteristicas clinicas y se realiza una revision de la bibliografia. Conclusiones. Debe resaltarse la importancia del conocimiento del sindrome para poder llevar a cabo su diagnostico, puesto que lo habitual es que, sin practicar la biopsia cutanea o el frotis de mucosa bucal, la anomalia cromosomica pasa desapercibida si se usan tecnicas citogeneticas clasicas. Hoy en dia, es posible realizar el diagnostico en sangre mediante array-CGH o array-SNP, si bien la posibilidad de encontrar la anomalia cromosomica depende del porcentaje de mosaicismo.

    Objective: To describe clinical, electrophysiological, and histopathological profile of vasculitic neuropathy in elderly subjects aged 65 years or more. Design: Retrospective chart review. Setting: Departments of Neurology and Neuropathology, National Institute of Mental Health and Neurosciences, Bengaluru, Karnataka, India. Patients and Methods: Elderly subjects, diagnosed vasculitic neuropathy by nerve biopsy over one decade, were studied. Results: The cohort consisted of 46 subjects. Symptom duration was 21.54 ± 33.53 months. Onset was chronic in majority (82.6%). Key features included paresthesias (89%), weakness (80%), sensory loss (70%), wasting (63%), and relapsing-remitting course (6.5%). Most Common clinico-electrophysiological patterns were distal symmetrical sensorimotor polyneuropathy - 19, mononeuritis multiplex - 9, and asymmetric sensorimotor neuropathy - 10. Diagnosis of vasculitis was not suspected before biopsy in 31 (67.3%). Nerve biopsy revealed definite vasculitis - 12, probable - 10, and possible - 24. Treatment included immunomodulatory agents (41), symptomatic medications only (9), and antiretroviral therapy (1). Twenty-four patients were followed up for mean period of 6.5 months. Outcome at last follow-up was improved (13), unchanged (8), and worsened (3). Conclusion: Vasculitis is an important, treatable cause of neuropathy in elderly. Nerve biopsy should be used judiciously for early diagnosis and appropriate treatment. PMID:27570382

    Aim: to investigate the events involved in the progression of myxoid liposarcoma (MLS). Gene expression profiling and immunohistochemical/biochemical analyses were applied to specimens representative of the opposite ends of the MLS spectrum: pure myxoid (ML) and pure round cell (RC) liposarcomas. The analyses revealed the involvement of both coding and non coding RNAs (SNORDs located in DLK1-DIO3 region) and support a model of stepwise progression mainly driven by epigenetic changes involving tumour vascular supply and tumoral cellular component. In this model, a switch in the vascular landscape from a normal to a pro-angiogenic signature and the silencing of DLK1-DIO3 region mark the progression from ML to RC in concert with the acquisition by the latter of the over-expression of YY1/C-MYC/HDAC2, together with over-expression of genes involved in cell proliferation and stemness: MKNK2, MSX1 and TRIM71. Taken together, these findings strongly suggest that to progress from ML to RC liposarcoma the cells have to overcome the epigenetic silencing restriction point in order to reset their new stem-like differentiation signature. Our findings provide a first attempt at identifying the missing links between ML and RC liposarcomas, that may also have broader applications in other clinico-pathological settings characterised by a spectrum of progression.

    Chronic lung disease (CLD) in children represents a heterogeneous group of many clinico-pathological entities with risk of adverse impact of chronic or intermittent hypoxia. So far, few researchers have investigated the cognitive function in these children, and the role of auditory P300 in the assessment of their cognitive function has not been investigated yet. This study was designed to assess the cognitive functions among schoolchildren with different chronic pulmonary diseases using both auditory P300 and Stanford-Binet test. This cross-sectional study included 40 school-aged children who were suffering from chronic chest troubles other than asthma and 30 healthy children of similar age, gender and socioeconomic state as a control group. All subjects were evaluated through clinical examination, radiological evaluation and spirometry. Audiological evaluation included (basic otological examination, pure-tone, speech audiometry and immittancemetry). Cognitive function was assessed by auditory P300 and psychological evaluation using Stanford-Binet test (4th edition). Children with chronic lung diseases had significantly lower anthropometric measures compared to healthy controls. They had statistically significant lower IQ scores and delayed P300 latencies denoting lower cognitive abilities. Cognitive dysfunction correlated to severity of disease. P300 latencies were prolonged among hypoxic patients. Cognitive deficits in children with different chronic lung diseases were best detected using both Stanford-Binet test and auditory P300. P300 is an easy objective tool. P300 is affected early with hypoxia and could alarm subtle cognitive dysfunction. PMID:27075686

    Extrapleural solitary fibrous tumors are uncommon mesenchymal neoplasms frequently observed in middle-aged adults and are classified, according to the WHO classification of soft tissue tumors, as part of the hemangiopericytoma tumor group. However, these two entities remain separated in the WHO classification of tumors of the central nervous system. In fact, meningeal solitary fibrous tumors are believed to be benign lesion and only in a minority of cases local relapses have been described, although detailed survival clinical studies on solitary fibrous tumors of meninges are rare. In contrast to hemangiopericytoma, which frequently shows distant extracranial metastases, such an event is exceptional in patients with meningeal solitary fibrous tumors and has been clinically reported in a handful of cases only and their histopathological features have not been investigated in detail. In this report, we describe the detailed clinico-pathological features of a meningeal solitary fibrous tumor presenting during a 17-year follow-up period, multiple intra-, extracranial relapses and lung metastases.

    Tuberous Sclerosis Complex (TSC) is a genetic hamartoma syndrome frequently associated with severe intractable epilepsy. In some TSC patients epilepsy surgery is a promising treatment option provided that the epileptogenic zone can be precisely delineated. TSC brain lesions (cortical tubers) contain dysmorphic neurons, brightly eosinophilic giant cells and white matter alterations in various proportions. However, a histological classification system has not been established for tubers. Therefore, the aim of this study was to define distinct histological patterns within tubers based on semi-automated histological quantification and to find clinically significant correlations. In total, we studied 28 cortical tubers and seven samples of perituberal cortex from 28 TSC patients who had undergone epilepsy surgery. We assessed mammalian target of rapamycin complex 1 (mTORC1) activation, the numbers of giant cells, dysmorphic neurons, neurons, and oligodendrocytes, and calcification, gliosis, angiogenesis, inflammation, and myelin content. Three distinct histological profiles emerged based on the proportion of calcifications, dysmorphic neurons and giant cells designated types A, B, and C. In the latter two types we were able to subsequently associate them with specific features on presurgical MRI. Therefore, these histopathological patterns provide consistent criteria for improved definition of the clinico-pathological features of cortical tubers identified by MRI and provide a basis for further exploration of the functional and molecular features of cortical tubers in TSC.

    Diabetes mellitus is a complex metabolic disorder characterized by chronic hyperglycemia, and associated with long-term damage and dysfunction of various organs. Management of diabetes is therefore vital and involves maintaining euglycemia as much as possible by reducing blood glucose and by increasing insulin sensitivity and peripheral glucose uptake. Ayurveda has promoted the management of diabetes by regulating carbohydrate metabolism using several medicinal herbs, one of which is Gymnema sylvestre (GS). GS has been used in parts of India as a hypoglycemic agent and the results have been encouraging. Accordingly, we planned a quasi-experimental study to investigate the efficacy of the herb among type 2 diabetics. Patients enrolled from free-living population were purposively assigned to experimental or control groups, based on their willingness to participate in the study. The experimental group was supplemented with 500 mg of the herb per day for a period of 3 months, and the efficacy of the herb was assessed through a battery of clinical and biochemical tests. Supplementation of the diet with GS reduced polyphagia, fatigue, blood glucose (fasting and post-prandial), and glycated hemoglobin and there was a favorable shift in lipid profiles and in other clinico-biochemical tests. These findings suggest a beneficial effect of GS in the management of diabetes mellitus.

    Abstract Psychosis has been recognized as a common feature in neurodegenerative diseases and a core feature of dementia that worsens most clinical courses. It includes hallucinations, delusions including paranoia, aggressive behaviour, apathy and other psychotic phenomena that occur in a wide range of degenerative disorders including Alzheimer’s disease, synucleinopathies (Parkinson’s disease, dementia with Lewy bodies), Huntington’s disease, frontotemporal degenerations, motoneuron and prion diseases. Many of these psychiatric manifestations may be early expressions of cognitive impairment, but often there is a dissociation between psychotic/behavioural symptoms and the rather linear decline in cognitive function, suggesting independent pathophysiological mechanisms. Strictly neuropathological explanations are likely to be insufficient to explain them, and a large group of heterogeneous factors (environmental, neurochemical changes, genetic factors, etc.) may influence their pathogenesis. Clinico-pathological evaluation of behavioural and psychotic symptoms (PS) in the setting of neurodegenerative and dementing disorders presents a significant challenge for modern neurosciences. Recognition and understanding of these manifestations may lead to the development of more effective preventive and therapeutic options that can serve to delay long-term progression of these devastating disorders and improve the patients’ quality of life. A better understanding of the pathophysiology and distinctive pathological features underlying the development of PS in neurodegenerative diseases may provide important insights into psychotic processes in general.

    There is a paucity of HIV autopsy data from South America and none that document the postmortem findings in patients with HIV/AIDS in Peru. The purpose of this autopsy study was to determine the spectrum of opportunistic infections and the causes of mortality in HIV-positive patients at a public hospital in Lima. Clinico-epidemiological information regarding HIV infection in Peru is also reviewed. Sixteen HIV-related hospital postmortems, performed between 1999 and 2004, were included in this retrospective analysis. The primary cause of death was established in 12 patients: one died of neoplasia and 11 of infectious diseases, including 3 from pulmonary infection, 7 from disseminated infection, and 2 from central nervous system infection (one case had dual pathology). Opportunistic infections were identified in 14 cases, comprising cytomegalovirus, histoplasmosis, cryptococcosis, toxoplasmosis, Pneumocystis pneumonia, aspergillosis, tuberculosis, varicella zoster virus, and cryptosporidiosis. Fourteen patients had at least one AIDS-related disease that had been neither clinically suspected nor diagnosed premortem. Moreover, 82% of the diagnoses considered to be of important clinical significance had not been suspected antemortem. The spectrum and frequency of certain opportunistic infections differed from other South American autopsy studies, highlighting the importance of performing HIV/AIDS postmortems in resource-limited countries where locally specific disease patterns may be observed.

    Phantom hCG refers to persistent mild elevations of hCG, leading physicians to unnecessary treatments whereas neither a true hCG nor a trophoblastic disease is present. We report the case of a 23-year-old woman with persistent low levels of serum hCG detected one month after miscarriage. As choriocarcinoma was suspected, a chemotherapy trial of methotrexate was prescribed, without any hCG reduction. Subsequently, laparoscopy ruled out a trophoblastic residue and the patient was referred to the Endocrine Unit for further investigations. While low levels of hCG were still detected in serum, no hCG was detected in the urine. In addition, when serum was processed in a HBT tube for revealing heterophilic antibodies, hCG was no longer detected. Such finding indicated the presence of phantom hCG due to heterophilic mouse antibodies interaction. This case raises the need of clinico-biological discussion to avoid inappropriate therapeutic decisions. Based on this case experience and after review of the literature, we suggest that current gynecological protocols for the diagnosis and treatment of trophoblastic disease should consider the inclusion of urinary hCG and/or a test for serum heterophilic antibodies when appropriate.

    In Creutzfeldt-Jakob disease (CJD), molecular typing based on the size of the protease resistant core of the disease-associated prion protein (PrP(Sc) ) and the M/V polymorphism at codon 129 of the PRNP gene correlates with the clinico-pathologic subtypes. Approximately 95% of the sporadic 129MM CJD patients are characterized by cerebral deposition of type 1 PrP(Sc) and correspond to the classic clinical CJD phenotype. The rare 129MM CJD patients with type 2 PrP(Sc) are further subdivided in a cortical and a thalamic form also indicated as sporadic fatal insomnia. We observed two young patients with MM2-thalamic CJD. Main neuropathological features were diffuse, synaptic PrP immunoreactivity in the cerebral cortex and severe neuronal loss and gliosis in the thalamus and olivary nucleus. Western blot analysis showed the presence of type 2A PrP(Sc) . Challenge of transgenic mice expressing 129MM human PrP showed that MM2-thalamic sporadic CJD (sCJD) was able to transmit the disease, at variance with MM2-cortical sCJD. The affected mice showed deposition of type 2A PrP(Sc) , a scenario that is unprecedented in this mouse line. These data indicate that MM2-thalamic sCJD is caused by a prion strain distinct from the other sCJD subtypes including the MM2-cortical form.

Los quistes oseos aneurismaticos espinales son lesiones osteoliticas benignas muy infrecuentes constituidas por cavidades hematicas limitadas por septos osteoconectivos y celulas gigantes tipo osteoclastos. Clinicamente se manifiestan con dolor local, sintomas neurologicos secundarios a compresion medular, asi como fracturas, deformidades e inestabilidad vertebral. Presentamos un caso de quiste oseo aneurismatico espinal dorsal con sintomatologia neurologica, tratado mediante una reseccion microquirurgica completa, sin secuelas neurologicas asociadas. Caso clinico. Mujer de 47 años, sin antecedentes traumaticos previos, valorada por presentar un cuadro de parestesias de los miembros inferiores de semanas de evolucion. El estudio radiologico de resonancia magnetica dorsal demostro la existencia de una lesion litica de bordes bien delimitados y esclerosis marginal en D4, con afectacion de los elementos posteriores vertebrales y compresion del cordon medular subyacente. La lesion fue extirpada en su totalidad, con desaparicion de la clinica sensitiva tras la intervencion. El diagnostico anatomopatologico definitivo fue quiste oseo aneurismatico espinal. Conclusion. A pesar de su baja incidencia, los quistes oseos aneurismaticos espinales deben considerarse, en el diagnostico diferencial de los tumores oseos espinales, como una posible causa de mielopatia compresiva subaguda o cronica. La reseccion tumoral completa se considera el tratamiento de eleccion, el cual con frecuencia es curativo y asocia un buen pronostico del paciente a largo plazo.

  7. Inflammatory markers of disease severity in acute pancreatitis.

    To date, CRP remains the single standard biochemical marker for predicting the severity of AP. Because the combination of clinico-physiological scores and CRP provides good information at 48 hours, research has focused on the predictive ability of various markers when applied in the initial 24 hours after admission to the hospital. After detailed review of the literature, the authors conclude that there is no single tool that serves as the optimal predictor of severity. There are, however, data supporting the use of certain tests to improve upon the clinician's early predictive ability on the subsequent course of AP. These include an APACHE II score greater than seven, IL-6 at the time of admission, and urine TAP, urine trypsinogen-2,and serum PMN-elastase at 24 hours (Box 1). These markers will only be able to help the clinician's predictive ability if they can be performed locally and if the results can be available in a timely manner. Future research should focus on markers such as procalcitonin, IL-8, IL-I ra, sTNFR,CAPAP, PLA-2, novel markers, and the combined use of more than one marker. The conventional research approach in predicting severity used in the last15 years has limitations and appears to have reached its maximal potential. Novel conceptions and approaches, such as identification of genetic polymorphisms that predispose to severe course and complications of AP, are needed for a quantum step forward.

    Sudden deaths in children due to acute encephalitis syndrome (AES) from a tribal dominated district of Malkangiri in Odisha, India, was reported during September-November, 2012. The investigation was carried out to search for the possible viral aetiology that caused this outbreak. Clinico-epidemiological survey and seromolecular investigation were carried out to confirm the viral aetiology. Two hundred seventy two suspected cases with 24 deaths were observed. The patients presented with low to moderate grade fever (87%), headache (43%), vomiting (27%), cold (18%), cough (17%), body ache (15%), joint pain (15%), rash (15%), abdomen pain (9%), lethargy (5%), altered sensorium (8%), convulsion (2%), diarrhoea (3%), and haematemesis (3%). Laboratory investigation showed Japanese encephalitis virus (JEV) IgM in 13.8 per cent (13/94) in blood samples and JEV RNA in one of two cerebrospinal fluid (CSF) samples. Paddy fields close to the houses, high pig to cattle ratio, high density (33 per man hour density) of Culex vishnui mosquitoes, low socio-economic status and low health awareness in the tribal population were observed. This report confirmed the outbreak of JEV infection in Odisha after two decades. PMID:26905239

    2013-01-01

    Pompe disease is a recessively inherited and often fatal disorder caused by the deficiency of acid α-glucosidase, an enzyme encoded by the GAA gene and needed to break down glycogen in lysosomes. This glycogen storage disease type II has been reported also in Swedish Lapphund dogs. Here we describe the genetic defect in canine Pompe disease and show that three related breeds from Scandinavia carry the same mutation. The affected dogs are homozygous for the GAA c.2237G>A mutation leading to a premature stop codon at amino acid position 746. The corresponding mutation has previously been reported in humans and causes infantile Pompe disease in combination with a second fully deleterious mutation. The affected dogs from both the Finnish as well as the Swedish breed mimic infantile-onset Pompe disease genetically, but also clinico-pathologically. Therefore this canine model provides a valuable tool for preclinical studies aimed at the development of gene therapy in Pompe disease. PMID:23457621

    Clinico-epidemiological and molecular studies have established the casual link between Human Papillomavirus (HPV) infection and cervical cancer as also association of HPV infection with several other cancers. In India, cervical cancer is a leading cancer among women and almost all cases of cervical cancer show prevalence of High Risk (HR)-HPV infection. HPV has been also detected in a significant proportion of oral, esophageal, anal, vaginal, vulvar, and penile cancer and in a small percentage of lung, laryngeal, and stomach cancer in India. Due to lack of organized HPV screening program, insufficient infrastructure and trained manpower and inadequacy in cancer registries, there are not much data available on the countrywide HPV prevalence and its type distribution in different cancers in India. Forthcoming introduction of recently developed HPV vaccines in India given a new urgency to know the prevalence and distribution of various HPV types in different organ sites for the management and monitoring of vaccination program and its impact on prevalence of other cancers. This review, summarizes studies on the prevalence of HPV infection in cancers of different organ sites in India.

    In the thyroid, primary neuroendocrine tumors encompass medullary thyroid carcinoma (MTC) and, rarely, other tumors such as paragangliomas. MTCs are derived from C-cells and express calcitonin and neuroendocrine markers. Besides classic MTC, some reports have documented thyroid neuroendocrine tumors, which show no calcitonin expression and raise difficult diagnostic problems. A 76-year-old man presented with a mass in the left thyroid with neither serological calcitonin elevation nor familial history. A thorough clinico-laboratorial study did not disclose any other mass elsewhere. A left hemithyroidectomy was performed, and the histological examination revealed a neuroendocrine carcinoma resembling a paraganglioma-like MTC displaying unequivocal signs of vascular invasion. Immunohistochemically, the tumor cells showed reactivity for chromogranin A, synaptophysin, thyroid transcription factor-1 (TTF-1), paired box gene 8 (PAX8), cytokeratins (AE1/AE3 and CK8/18), and calcitonin gene-related peptide (CGRP) and negativity for calcitonin, carcinoembryonic antigen, TTF-2, thyroperoxidase, and thyroglobulin. In situ hybridization showed that the tumor cells lacked expression for calcitonin and thyroglobulin mRNA. Genetic analysis did not disclose any RET mutation. A diagnosis of C-cell-derived primary neuroendocrine carcinoma of the thyroid without calcitonin expression was made, and the patient remains free of metastasis or recurrence 18 months after surgery.

    Autosomal-dominant optic atrophy (ADOA) is the most common inherited optic neuropathy, due to mutations in the optic atrophy 1 gene (OPA1) in about 60%-80% of cases. At present, the clinical heterogeneity of patients carrying OPA1 variants renders genotype-phenotype correlations difficulty. Since 2005, when we published the first locus-specific database (LSDB) dedicated to OPA1, a large amount of new clinical and genetic knowledge has emerged, prompting us to update this database. We have used the Leiden Open-Source Variation Database to develop a clinico-biological database, aiming to add clinical phenotypes related to OPA1 variants. As a first step, we validated this new database by registering several patients previously reported in the literature, as well as new patients from our own institution. Contributors may now make online submissions of clinical and molecular descriptions of phenotypes due to OPA1 variants, including detailed ophthalmological and neurological data, with due respect to patient anonymity. The updated OPA1 LSDB (http://opa1.mitodyn.org/) should prove useful for molecular diagnoses, large-scale variant statistics, and genotype-phenotype correlations in ADOA studies.

    2004-09-01

    An extraordinary case of encapsulated fat necrosis characterized by its large size, diffuse formation of pseudomembranes, and tendency to recur after excision is reported. A 67-year-old Caucasian woman suffering from morbid obesity was admitted for diagnosis and surgical treatment of a soft tissue mass showing a longest diameter of 14 cm and lying adjacently to the scar from previous appendicectomy. Histopathologic features were consistent with a nodular-cystic encapsulated fat necrosis with diffuse pseudomembranous transformation. Eight months after surgery, a new larger mass (longest diameter of 18 cm) sharing identical histopathologic features appeared in the same location. Encapsulated fat necrosis is a well-defined entity even though several names have been proposed for this condition, including mobile encapsulated lipoma, encapsulated necrosis, or nodular-cystic fat necrosis. Its pathogenesis seems to be related to ischemic changes secondary to previous trauma. It may occasionally show degenerative changes, including dystrophic calcifications and presence of pseudomembranes. To our knowledge, these are the first reported cases of encapsulated fat necrosis presenting as lesions of such size and showing diffuse formation of pseudomembranes; these particular features made diagnosis difficult and led to consideration of a wide range of potential diagnostic possibilities. This case expands the clinico-pathologic spectrum of membranocystic fat necrosis, including the potential ability of this subcutaneous fatty tissue abnormality to recur after surgical excision.

    Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare subtype of leukemia/lymphoma, whose diagnosis can be difficult to achieve due to its clinical and biological heterogeneity, as well as its overlapping features with other hematologic malignancies. In this study we investigated whether the association between the maturational stage of tumor cells and the clinico-biological and prognostic features of the disease, based on the analysis of 46 BPDCN cases classified into three maturation-associated subgroups on immunophenotypic grounds. Our results show that blasts from cases with an immature plasmacytoid dendritic cell (pDC) phenotype exhibit an uncommon CD56− phenotype, coexisting with CD34+ non-pDC tumor cells, typically in the absence of extramedullary (e.g. skin) disease at presentation. Conversely, patients with a more mature blast cell phenotype more frequently displayed skin/extramedullary involvement and spread into secondary lymphoid tissues. Despite the dismal outcome, acute lymphoblastic leukemia-type therapy (with central nervous system prophylaxis) and/or allogeneic stem cell transplantation appeared to be the only effective therapies. Overall, our findings indicate that the maturational profile of pDC blasts in BPDCN is highly heterogeneous and translates into a wide clinical spectrum -from acute leukemia to mature lymphoma-like behavior-, which may also lead to variable diagnosis and treatment.

    Among 65 patients admitted to the hospital for chronic obstructive lung disease, the following pulmonary tests were systematically performed : spirometric vital capacity and total lung capacity, FEV1, functional residual capacity and total lung capacity measured by body plethysmography, airway resistance and specific conductance, CO diffusion capacity measured by single-breath test, N2 clearance by single breath oxygen dilution, and blood gases. The patients were divided into bronchitics, emphysematous and broncho-emphysematous, according to the clinical and radiological Nash's score, and to another personal score derived from the former. The simple and multiple correlations between the clinico-radiological score and the functional results are low. The clustering analysis groups the 65 patients into four clouds of points, around two principal axes : the volume axis and the overinflation axis. This study indicates that the most suggestive results for emphysema diagnosis are increased FRC and TLC and low Tlco/V'a. The clinical score is not dominant for the clustering of the patients into the dynamic clouds. Beneath the bronchitic, the broncho-emphysematous and the emphysematous groups, the clustering analysis individualizes a fourth group of cases characterized by chronic asthma, and which were not isolated by Nash's score.

    RIASSUNTO. Lo scopo del presente studio è quello di esplorare le proprietà psicometriche di uno strumento di misurazione dell'affetto, la Scala di Esperienze Positive e Negative (SPANE), all'interno di una popolazione italiana. Gli esiti dell'analisi fattoriale confermativa comprovano l'attesa struttura a due fattori, sentimenti positivi e negativi. Le correlazioni con altre dimensioni (per es., ansia, depressione, affetto, aspettative future) confermano i risultati ottenuti con le precedenti versioni della scala: affetto negativo, ansia, depressione e aspettative future negative correlano positivamente con la subscala di esperienze negative e negativamente con la subscala di esperienze positive dello SPANE. In conclusione, i risultati del nostro studio dimostrano che la versione italiana dello SPANE presenta caratteristiche psicometriche simili a quelle mostrate dalla versione orginale e da successive validazioni dello strumento in altre lingue. La scala presenta, inoltre, affidabilità e validità fattoriale. Lo SPANE è un indice utile dal punto di vista clinico che può fornire informazioni rilevanti circa l'esperienza emotiva e il benessere della persona. Nonostante ulteriori studi siano necessari per confermare le caratteristiche psicometriche della scala, la presente validazione della versione italiana dello SPANE può contribuire ad ampliare la ricerca nell'ambito del benessere in una popolazione Italiana.

  17. Eosinophilic esophagitis: New insights in pathogenesis and therapy.

    PubMed

    Guarino, Michele Pier Luca; Cicala, Michele; Behar, Jose

    2016-02-01

    Eosinophilic esophagitis (EoE) is a clinico-pathological entity with esophageal symptoms and dense esophageal eosinophilic infiltration throughout the esophagus that may persist despite treatment with proton pump inhibitors. This eosinophilic infiltration is usually absent in the stomach, small intestine and colon, although there are a number of reports of patients with a multi-organ involvement. EoE is associated with abnormalities involving TH2-dependent immunity, with multiple environmental factors strongly contributing to disease expression. The layer of the esophagus affected by the eosinophilic infiltration causes the specific symptoms. Esophageal involvement results mostly in dysphagia for solids that can be severe enough to cause recurrent esophageal obstruction with typical endoscopic features suggesting esophageal remodeling and pathological changes of eosinophilic infiltration of the mucosa, sub-epithelial fibrosis and muscle hypertrophy. This disease is frequently associated with other allergic conditions such as allergic asthma, allergic dermatitis and eosinophilia. The treatment of patients with EoE depends on the severity of the symptoms and of the inflammatory process as well as to their response to a gradual step-up treatment. The first line of treatment consists of steroid containing local inhalers. If unresponsive they are then treated with oral steroids. Intravenous interleukin blockers seem to have a consistent positive therapeutic effect. PMID:26855813

    Introduzione: La competenza è un elemento fondamentale quando si misura la capacità di infer- mieri o studenti di fornire assistenza infermieristica, ma non vi è consenso su ciò che realmente sia la competenza. Questo studio si propone di indagare i significati e i modelli di competenza infermieristica. Metodo: L’overview delle revisioni della letteratura e delle concept analysis è stata effettuata attraverso una ricerca su Pubmed, Cinahl e PsychINFO dal gennaio 2005 a settembre 2014, che includeva parole chiave come: Modello di competenza; Competenza professionale; Competenza infermieristica; Competenza. Risultati: Sono stati inclusi un totale di 14 articoli, provenienti dalla letteratura infermieristica sia in ambito formativo che clinico. È stato possibile individuare alcuni temi comuni negli arti- coli inclusi: la descrizione dei determinanti di competenza; la confusione intorno al concetto di competenza; la carenza nella valutazione delle competenze; la carenza nell’operazionalizzare il concetto di competenza. Conclusioni: I risultati forniscono una panoramica che, arricchita dalla letteratura proveniente dagli studi organizzativi, costituiscono la base concettuale di un modello integrato di compe- tenza infermieristica. Ulteriore ricerca empirica è necessaria per verificare le assunzioni teoriche.

    The following communication summarizes the proceedings of a 1-day Workshop of the International Melanoma Pathology Study Group, which was devoted to thin melanoma. The definitions and histologic criteria for thin melanoma were reviewed. The principal differential diagnostic problems mentioned included the distinction of thin melanoma from nevi, especially from nevi of special site, irritated nevi, inflamed and regressing nevi, and dysplastic nevi. Histologic criteria for this analysis were discussed and the importance of clinico-pathologic correlation, especially in acral sites, was emphasized. Criteria for the minimal definition of invasion were also discussed. In addition, a new technique of m-RNA expression profiling with 14 genes was presented and facilitated the distinction of thin melanomas from nevus in histologically obvious cases. However, for particular nevi, it was not obvious why the results indicated a malignant lesion. Despite many molecular and other ancillary investigations, Breslow thickness remains the most important prognostic factor in thin melanoma. The prognostic significance of radial (horizontal) and vertical growth phases, Clark level, regression, and mitotic rate were also discussed. Because of the increasing frequency of thin melanomas, there is a great need to develop more refined predictors of thin melanomas with worse clinical outcome. PMID:26645459

    Introduccion. La cefalea en racimos es una cefalea primaria de origen trigeminoautonomico cuyo inicio en la infancia es infrecuente. Se presentan cuatro casos en los que el inicio de la sintomatologia se produjo entre los 2 y los 13 años. Casos clinicos. Se incluyen tres varones y una niña con inicio a los 2, 7, 13 y 12 años, respectivamente. Los cuatro pacientes cumplen los criterios propuestos por la tercera edicion de la Clasificacion Internacional de las Cefaleas ICHD-III (beta). Conclusiones. A pesar de ser poco frecuente durante la edad pediatrica, la cefalea en racimos debe formar parte del diagnostico diferencial de un niño que consulta por cefalea. Subrayamos la importancia de conocer sus criterios diagnosticos para evitar el retraso diagnostico que se ha descrito con frecuencia. En nuestros pacientes, el tratamiento con verapamilo resulto mas eficaz que el tratamiento con flunaricina. Los tratamientos con mejor respuesta en fase aguda fueron la oxigenoterapia y los triptanes.

    African countries can concentrate mainly on operational and problem-solving type of medical research using as a basis routine diagnostic laboratory parasitology which can be elevated to research level by incorporating all relevant techniques backed by statistically-based programming. Because of high incidence of parasitic infections and the peculiar host-parasite relationship, co-operation between all departments of any major hospital will be required to deal with the diseases due to them. Longitudinal studies on some parasites will enable generalisation and specific views to be formed on some infections. Multiplicity and wide variety of available techniques offer several research possibilities of clinico-pathological and epidemiological significance. Routine laboratory-based research offers the right environment for training various types of laboratory workers from technicians to medical parasitologists, through on-the-job training on techniques, investigative studies and research, backed by formal lectures and practicals at various levels. Trainee medical parasitologists can obtain higher degrees locally or abroad. The research can be organised around micro and mini research units. This approach is cost-beneficial because it minimises administrative difficulties and so avoids wastage. The results can be used to monitor impact of national development on parasitic infection prevalence and to formulate a policy on parasitic disease management.

    Introduccion. Las celulas madre constituyen una alternativa terapeutica que se encuentra en fase de experimentacion para el infarto cerebral. Objetivo. Mostrar la evidencia cientifica existente sobre el potencial terapeutico de las celulas madre de la medula osea en esta enfermedad. Desarrollo. El infarto cerebral representa el 80% de las enfermedades cerebrovasculares. La trombolisis constituye la unica terapia aprobada, pero, por su estrecha ventana terapeutica, solo se aplica a un bajo porcentaje de los pacientes. De manera alternativa, los tratamientos neurorrestauradores, como el de celulas madre, pueden aplicarse en periodos mas prolongados. Por esta razon se efectuo una busqueda bibliografica en PubMed con el empleo de las palabras clave 'stem cells', 'bone marrow derived mononuclear cells' y 'stroke'. Se encontraron evidencias de seguridad y eficacia de dichas celulas en diferentes momentos evolutivos del infarto cerebral. Se identificaron estudios que en clinica y preclinica las recolectaron por puncion medular y en sangre periferica, y las trasplantaron directamente en el area infartada o por via intravascular. El efecto terapeutico se relaciona con sus propiedades de plasticidad celular y liberacion de factores troficos. Conclusiones. El concentrado de celulas mononucleares autologas, obtenido en sangre periferica o por puncion de la medula osea, y trasplantado por via intravenosa, es una factible opcion metodologica que permitira rapidamente incrementar el numero de ensayos clinicos en diferentes etapas evolutivas del infarto cerebral. Esta terapia muestra seguridad y eficacia; sin embargo, deben ampliarse las evidencias que avalen su generalizacion en humanos.

    Introduccion. El botulismo es un sindrome causado por la toxina del bacilo Clostridium botulinum. La toxina actua bloqueando las terminaciones colinergicas presinapticas de la placa motora y del sistema nervioso parasimpatico, y ocasiona una paralisis flacida y un fallo parasimpatico. El modo mas habitual de adquisicion de la enfermedad es por ingesta de toxina preformada presente en las conservas caseras mal esterilizadas, aunque otros mecanismos son posibles. Su incidencia actual en Espana es muy baja. Casos clinicos. Se describen tres miembros convivientes de una familia que presentaron un cuadro de botulismo alimentario. Las manifestaciones clinicas iniciales mostraron predileccion por la paresia ocular y por sintomatologia disautonomica de escasa especificidad, y la agregacion familiar fue el indicio fundamental que sugirio el diagnostico. Posteriormente, los pacientes empeoraron y dos de ellos presentaron afectacion de la funcion respiratoria y precisaron ingreso prolongado en la unidad de cuidados intensivos. Los tres pacientes convalecieron y se recuperaron sin secuelas. Se consiguio detectar la toxina botulinica por bioensayo en los restos de alimentos, lo que confiere al caso la categoria diagnostica de confirmado. Conclusiones. La microepidemia familiar presentada constituye un caso de afectacion inicial predominantemente ocular y disautonomica. Asimismo, ilustra varios aspectos tipicos de la enfermedad: la sospecha diagnostica ante pacientes convivientes que acuden simultaneamente por clinica similar, las complicaciones caracteristicas del proceso y su tratamiento, el diagnostico de laboratorio y su historia natural hacia la resolucion.

Caso clinico. Niño de 11 años con complejo esclerosis tuberosa y epilepsia refractaria del lobulo frontal izquierdo, evaluado en el contexto de un programa de cirugia de la epilepsia pediatrica. La zona epileptogena se relaciono con un tuber epileptogeno localizado en el giro frontal inferior del hemisferio izquierdo. Los efectos de altas dosis de zonisamida mimetizaron una afectacion de la corteza elocuente en la zona epileptogena y un impacto de las crisis no controladas en el funcionamiento cognitivo asociado al hemisferio dominante para el lenguaje. La retirada del farmaco mejoro significativamente, mas alla de los efectos de practica, el cociente intelectual total, el indice intelectual de comprension verbal y habilidades cognitivas especificas sustentadas en el lenguaje. Conclusiones. La diferenciacion entre los efectos cognitivos de los farmacos y la existencia de un deficit funcional por afectacion de la corteza elocuente en el area epileptogena puede ser crucial para la toma de decisiones en cirugia de la epilepsia.

Se presentan tres casos manifestados de forma muy diferente y tratados con terapia enzimatica sustitutiva (TES), con evolucion favorable. Casos clinicos. Caso 1: varon de 3 meses, con debilidad y rechazo de la alimentacion, hepatomegalia leve, ligera macroglosia e hipotonia, y aumento de las enzimas musculares. Caso 2: varon de 5 meses, con retraso del desarrollo motor, sordera neurosensorial grave, trastornos respiratorios de repeticion de evolucion torpida, hipotonia y leve elevacion de la creatincinasa. Caso 3: varon de 22 años con disnea progresiva, con antecedentes de elevacion de la creatincinasa y las transaminasas, e hipercolesterolemia. Sufrio insuficiencia respiratoria grave que preciso intubacion endotraqueal. La biopsia muscular presento depositos de glucogeno sugestivos de la enfermedad. En los tres casos, el estudio electromiografico dio un patron caracteristico, con descargas pseudomiotonicas, y se confirmo el deficit de AGA en los linfocitos. Se encontro una mutacion en un caso y dos mutaciones en los otros dos. Todos recibieron TES con evolucion favorable: desaparicion de las alteraciones cardiacas en el caso 1, mejoria en los hitos motores en los dos casos infantiles y retirada del respirador en el caso 3. Conclusion. La enfermedad de Pompe tiene una amplia variabilidad en la expresion clinica. La TES consigue una buena respuesta, especialmente en las formas infantiles. La supervivencia a largo plazo de las formas infantiles tratadas permitira conocer mas aspectos del curso de la enfermedad.

La fractura craneal evolutiva, tambien llamada absorcion osea postraumatica o quiste leptomeningeo, es una rara complicacion de los traumatismos craneoencefalicos y ocurre de forma casi exclusiva en ninos menores de 3 anos. Caso clinico. Nino de 6 meses que presentaba, dos meses despues de un traumatismo craneal aparentemente banal, persistencia de cefalohematoma temporooccipital izquierdo sin otros signos. El estudio de ecografia transfontanelar revelo un defecto oseo con herniacion cerebral, y la tomografia computarizada y la resonancia magnetica confirmaron, ademas, una fractura evolutiva. Se realizo reseccion del quiste encefalomeningeo, cierre dural y reparacion del defecto oseo con placas y material de lactato. Tres meses despues de la intervencion, presentaba persistencia de coleccion liquida y se confirmo recidiva de la fractura evolutiva. Tras la reintervencion, se coloco casco ortesico para evitar nuevas recidivas. Un ano despues del traumatismo, el paciente continua asintomatico. Conclusiones. Todo nino menor de 3 anos con cefalohematoma postraumatico deberia ser revisado de forma periodica hasta comprobar la resolucion de la coleccion, en particular si presenta fractura craneal. La presencia de un cefalohematoma persistente mas de dos semanas despues de un traumatismo craneoencefalico debe hacernos sospechar un proceso de fractura creciente, y son necesarias la reparacion de la duramadre y una craneoplastia para su tratamiento. La colocacion de material reabsorbible permite su remodelacion con el crecimiento craneal del paciente, pero su fragilidad conlleva riesgo de recidiva. La colocacion de un casco ortesico tras la intervencion podria prevenir complicaciones.

    Purpose The tumor suppressor p53 is known to be inactivated frequently in various cancers. In addition, germline polymorphisms in TP53 are known to affect protein function and influence risk of developing different types of cancers. In this study, we analyzed the association of TP53 Pro72Arg polymorphism with squamous cell carcinoma of oral tongue (SCCOT) and esophagus (ESCC) in India. Methods We assessed the distribution of TP53 Pro72Arg polymorphism in one hundred and fifteen and eighty two SCCOT and ESCC patients, respectively, with respect to one hundred and ten healthy controls from the same population. In addition, we analyzed association of the polymorphism with several clinico-pathological and molecular parameters. Results Pro72 allele was significantly enriched in SCCOT patients compared to the healthy control group but neither allele was enriched in ESCC. Interestingly, Pro72 allele was preferentially mutated in ESCC which was confirmed by analysis of samples heterozygous for Pro72Arg. Conclusions Our study revealed the association of Pro72 allele with SCCOT suggesting the effect of this polymorphism on SCCOT risk. Preferential mutation of Pro72 allele exclusively in ESCC indicates the need for further studies to understand the tissue specific effect of p53 polymorphism. PMID:25436609

    There is a paucity of HIV autopsy data from South America and none that document the postmortem findings in patients with HIV/AIDS in Peru. The purpose of this autopsy study was to determine the spectrum of opportunistic infections and the causes of mortality in HIV-positive patients at a public hospital in Lima. Clinico-epidemiological information regarding HIV infection in Peru is also reviewed. Sixteen HIV-related hospital postmortems, performed between 1999 and 2004, were included in this retrospective analysis. The primary cause of death was established in 12 patients: one died of neoplasia and 11 of infectious diseases, including 3 from pulmonary infection, 7 from disseminated infection, and 2 from central nervous system infection (one case had dual pathology). Opportunistic infections were identified in 14 cases, comprising cytomegalovirus, histoplasmosis, cryptococcosis, toxoplasmosis, Pneumocystis pneumonia, aspergillosis, tuberculosis, varicella zoster virus, and cryptosporidiosis. Fourteen patients had at least one AIDS-related disease that had been neither clinically suspected nor diagnosed premortem. Moreover, 82% of the diagnoses considered to be of important clinical significance had not been suspected antemortem. The spectrum and frequency of certain opportunistic infections differed from other South American autopsy studies, highlighting the importance of performing HIV/AIDS postmortems in resource-limited countries where locally specific disease patterns may be observed.

    Introduccion. La encefalitis asociada a anticuerpos antirreceptores de N-metil-D-aspartato (NMDA) es una patologia neurologica autoinmune documentada en la poblacion pediatrica de manera creciente en los ultimos años. Se presentan dos casos de nuestra experiencia con clinica similar. Casos clinicos. Caso 1: niña de 5 años que inicia un cuadro de convulsiones y alteracion de conciencia, asociando trastornos del movimiento y regresion de habilidades previamente adquiridas que evoluciona a autismo. Caso 2: niña de 13 años que presenta hemiparesia izquierda, movimientos anomalos, trastorno de conducta y disautonomia. En ambos casos se obtienen anticuerpos antirreceptores de NMDA positivos en el liquido cefalorraquideo y se diagnostican de encefalitis antirreceptor de NMDA. En el primer caso se inicia el tratamiento con perfusion intravenosa de corticoides e inmunoglobulinas y es necesario asociar rituximab. En el segundo, corticoides e inmunoglobulinas. La evolucion fue favorable en ambas pacientes, con una leve alteracion del lenguaje como secuela en el primer caso y una recaida en el segundo caso, con resolucion completa. Conclusion. La encefalitis antirreceptor de NMDA es un trastorno tratable y es importante el diagnostico y tratamiento precoz, ya que mejora el pronostico y disminuye las recaidas.

    In this study, we evaluated whether the presence of genetic alterations detected by next generation sequencing may define outcome in a prognostically-selected and histology-restricted population of resected gastric cancer (RGC). Intestinal type RGC samples from 34 patients, including 21 best and 13 worst prognostic performers, were studied. Mutations in 50 cancer-associated genes were evaluated. A significant difference between good and poor prognosis was found according to clinico-pathologic factors. The most commonly mutated genes in the whole population were PIK3CA (29.4%), KRAS (26.5%), TP53 (26.5%) MET (8.8%), SMAD4 (8.8%) and STK11 (8.8%). Multiple gene mutations were found in 14/21 (67%) patients with good prognosis, and 3/13 (23%) in the poor prognosis group. A single gene alteration was found in 5/21 (24%) good and 6/13 (46%) poor prognosis patients. No mutation was found in 2/21 (9.5%) and 4/13 (31%) of these groups, respectively. In the overall series, ß-catenin expression was the highest (82.4%), followed by E-Cadherin (76.5%) and FHIT (52.9%). The good prognosis group was characterized by a high mutation rate and microsatellite instability. Our proof-of-principle study demonstrates the feasibility of a molecular profiling approach with the aim to identify potentially druggable pathways and drive the development of customized therapies for RGC.

Los efectos neuroprotectores de los analogos del GLP-1 se han puesto de manifiesto en estudios recientes y han abierto nuevos campos de investigacion en trastornos neurodegenerativos como la enfermedad de Alzheimer (EA), entre otros. Objetivo. Revision sistematica de los estudios experimentales y ensayos clinicos en humanos que demuestran las propiedades neuroprotectoras de los analogos del GLP-1 en la EA. Desarrollo. Los estudios experimentales que se han llevado a cabo en modelos de roedores con EA demuestran las propiedades neuroprotectoras de los analogos del GLP-1 sobre el sistema nervioso central que reducen las placas de beta-amiloide, el estres oxidativo y la respuesta inflamatoria cerebral. Recientemente se han puesto en marcha estudios con analogos del GLP-1 en humanos con deterioro cognitivo y EA. Conclusiones. Los analogos del GLP-1 presentan propiedades neuroprotectoras. Al considerarse la diabetes tipo 2 un factor de riesgo para el deterioro cognitivo y la demencia, deben considerarse los beneficios de los analogos del GLP-1 sobre la cognicion. Del mismo modo, los analogos del GLP-1 suponen un tratamiento prometedor en la EA.

    Introduccion. El natalizumab es un farmaco utilizado en la esclerosis multiple (EM), cuyo principal efecto adverso es el desarrollo de una leucoencefalopatia multifocal progresiva (LMP). Como esta es potencialmente mortal o discapacitante, el tratamiento debe suspenderse inmediatamente ante su sospecha, teniendo en cuenta el posible desarrollo posterior de un sindrome de reconstitucion inmune o rebrote de la EM. Caso clinico. Se describe un caso de LMP, inicialmente asintomatico, en el contexto del tratamiento con natalizumab en una paciente con EM. Como factores de riesgo se determinaron titulos altos de anticuerpos contra el virus John Cunningham (VJC) y mas de dos años de tratamiento. La reaccion en cadena de la polimerasa para el VJC en el liquido cefalorraquideo resulto negativa en dos determinaciones. El periodo entre el diagnostico radiologico y el inicio de la clinica fue de dos meses. Durante el curso de la enfermedad, la paciente desarrollo un sindrome inflamatorio de reconstitucion inmune y rebrotes de su EM. Presento una buena respuesta tras el inicio de tratamiento con fingolimod, una vez estabilizada la LMP. Conclusion. Este caso ilustra la importancia de una estrecha vigilancia clinicorradiologica en pacientes con EM tratados con natalizumab, sobre todo cuando presentan factores de riesgo para el desarrollo de LMP, asi como su potencial incidencia en la supervivencia y estado funcional final.

    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

    Age at onset (AAO) has been shown to influence the phenotype of Alzheimer's disease (AD), but how it affects atypical presentations of AD remains unknown. Posterior cortical atrophy (PCA) is the most common form of atypical AD. In this study, we aimed to investigate the effect of AAO on cortical thickness and cognitive function in 98 PCA patients. We used Freesurfer (v5.3.0) to compare cortical thickness with AAO both as a continuous variable, and by dichotomizing the groups based on median age (58 years). In both the continuous and dichotomized analyses, we found a pattern suggestive of thinner cortex in precuneus and parietal areas in earlier-onset PCA, and lower cortical thickness in anterior cingulate and prefrontal cortex in later-onset PCA. These cortical thickness differences between PCA subgroups were consistent with earlier-onset PCA patients performing worse on cognitive tests involving parietal functions. Our results provide a suggestion that AAO may not only affect the clinico-anatomical characteristics in AD but may also affect atrophy patterns and cognition within atypical AD phenotypes.

    Both sheep and goat pox are contagious viral diseases and affect small ruminants and are caused by sheep pox virus and goat pox virus respectively that belong to genus Capripoxvirus of Poxviridae family. Huge economic losses emanating from the disease outbreaks are the results of the wool and hide damage, subsequent production losses and also the morbidities and mortalities associated with the disease. This communication highlights clinico-epidemiological observations from the two sheep pox and one goat pox outbreaks. Grossly, multisystemic nodular lesions, mucopurulent nasal discharges and respiratory symptoms were observed in the affected animals. The morbidity, mortality and case fatality rates were 5.18%, 2.45% and 32.37%, respectively. Histopathological, haematological, molecular and serological techniques and also isolation of virus in embryonated chicken eggs were used for the diagnosis of the diseases. The spatial distribution of the disease signifies the role of common pasturelands used for grazing the animals while temporally all three outbreaks occurred in winters and were probably associated with cold stress and fodder scarcity. This is the first recorded report of Capripoxvirus infection in recent times and it highlights the disease as one of the emerging diseases in the northern state of Himachal Pradesh in India.

    Background: The epidermal growth factor receptor-targeted monoclonal antibody cetuximab (Erbitux) was recently introduced for the treatment of metastatic colorectal cancer. Treatment response is dependent on Kirsten-Ras (K-Ras) mutation status, in which the majority of patients with tumour-specific K-Ras mutations fail to respond to treatment. Mutations in the oncogenes B-Raf and PIK3CA (phosphoinositide-3-kinase) may also influence cetuximab response, highlighting the need for a sensitive, accurate and quantitative assessment of tumour mutation burden. Methods: Mutations in K-Ras, B-Raf and PIK3CA were identified by both dideoxy and quantitative pyrosequencing-based methods in a cohort of unselected colorectal tumours (n=102), and pyrosequencing-based mutation calls correlated with various clinico-pathological parameters. Results: The use of quantitative pyrosequencing-based methods allowed us to report a 13.7% increase in mutation burden, and to identify low-frequency (<30% mutation burden) mutations not routinely detected by dideoxy sequencing. K-Ras and B-Raf mutations were mutually exclusive and independently associated with a more advanced tumour phenotype. Conclusion: Pyrosequencing-based methods facilitate the identification of low-frequency tumour mutations and allow more accurate assessment of tumour mutation burden. Quantitative assessment of mutation burden may permit a more detailed evaluation of the role of specific tumour mutations in the pathogenesis and progression of colorectal cancer and may improve future patient selection for targeted drug therapies.

    Primary mediastinal B-cell lymphoma (PMBL) seems to be reliably distinguished from diffuse large B-cell lymphoma (DLBCL) with microarray technology. We measured expression of Fcer2, Pdl2 and Blk genes using real-time quantitative polymerase chain reaction (RTqPCR) on formalin fixed, paraffin embedded material (FFPE) and suggested a formula to discriminate PMBL from DLBCL. For 39/82 included patients the diagnosis of PMBL was expected clinico-pathologically. Diagnosis of 10/39 and 2/43 of clinically considered PMBLs and DLBCLs, respectively, was not genetically confirmed. Compared to confirmed PMBLs, unconfirmed ones showed clinical features similar to DLBCLs, e.g. spleen infiltration (p=0,028) and decreased invasiveness in pericardium (p=0,045). They tended to have more common infradiaphragmatic involvement, less often tumor sclerosis or fluidothorax. There were no immunohistochemical differences between genetically confirmed and unconfirmed PMBLs. New approach of distinguishing PMBL and DLBCL is presented. It is based on expression of three genes in routinely available FFPE material using RTqPCR. PMID:20568899

    The significance of many BRCA unclassified variants (UVs) has not been evaluated. Classification of these variations as neutral or pathogenic presents a significant challenge and has important implications for breast and ovarian cancer genetic counseling. Here we report a combined molecular and computational approach to classify BRCA UVs missense variations. By using the LOH (Loss of heterozygosity) analysis at the BRCA1/BRCA2 loci, five bioinformatics approaches namely fathmm, PhD-SNP, SNAP, MutationTaster and Human Splicing Finder and the association with the clinico-pathological characteristics related to BRCA tumors, we were able to classify the R2787H (in BRCA2 gene) variant as pathogenic. Then, to investigate the functional role of the R2787H variation in altering BRCA2 structure, the homology model of this variant was constructed using the Rattus norvegicus BRCA2 (PDB ID: 1IYJ) as a template. The predicted model was then assessed for stereochemical quality and side chain environment. Furthermore, docking and binding free energy simulations were performed to investigate the ssDNA-BRCA2 complex interaction. Binding energy value calculation proves that this substitution affects the complex stability. Moreover, this alteration was not found in one hundred healthy controls. These findings suggest that R2787H variant could have potential functional impact. Our approach might be useful for evaluation of BRCA unclassified variants. However additional functional analyzes may provide appropriate assessment to classify such variants. PMID:27211102
